Sample records for model-measurement discrepancy ensuring

  1. Toward resolving model-measurement discrepancies of radon entry into houses

    1994-10-01

    Analysis of the literature indicated that radon transport models significantly and consistently underpredict the advective entry into houses of soil-gas borne radon. Advective entry is the dominant mechanism resulting in high concentrations of radon indoors. The author investigated the source of the model-measurement discrepancy via carefully controlled field experiments conducted at an experimental basement located in natural soil in Ben Lomond, California. Early experiments at the structure confirmed the existence and magnitude of the model-measurement discrepancy, ensuring that it was not merely an artifact of inherently complex and poorly understood field sites. The measured soil-gas entry rate during structure depressurization was found to be an order of magnitude larger than predicted by a current three-dimensional numerical model of radon transport. The exact magnitude of the discrepancy depends on whether the arithmetic or geometric mean of the small-scale measurements of permeability is used to estimate the effective permeability of the soil. This factor is a critical empirical input to the model and was determined for the Ben Lomond site in the typical fashion using single-probe static depressurization measurements at multiple locations. The remainder of the dissertation research tests a hypothesis to explain the observed discrepancy: that soil permeability assessed using relatively small-scale probe measurements does not reflect bulk soil permeability for flows that is likely to occur at larger scales of several meters or more in real houses and in the test structure. The idea is that soil heterogeneity is of a nature that, as flows occur over larger scales, larger scales of heterogeneity are encountered that facilitate larger flux rates, resulting in a scale dependence of effective soil permeability

    We show that the modular transformations for one point functions on the torus, S(n), satisfy the polynomial equations derived by Moore and Seiberg, provided the duality property of the model is ensured. The formula for S(n) is derived by us previously and should be valid for any conformal field theory. As a consequence, the full consistency conditions for modular invariance at higher genus are completely guaranteed by duality of the theory on the sphere. (orig.)

    Discrepancies in blood typing is one of the major reasons in eliciting a transfusion reaction. These discrepancies can be avoided through detailed analysis for the blood typing. Here, we report a subgroup of blood group type-B in the ABO system. Donor's blood was analyzed by employing commercial antisera for blood grouping. The results of forward (known antisera) and reverse (known antigen) reaction were not complimentary. A detailed analysis using the standard protocols by American Association of Blood Banking revealed the blood type as a variant of blood group-B instead of blood group-O. This is suggestive of the fact that blood group typing should be performed with extreme care and any divergence, if identified, should be properly resolved to avoid transfusion reactions. Moreover, a major study to determine the blood group variants in Pakistani population is needed. (author)

The subject of in-depth consideration is the problem related to ensuring food safety. A critical review and analysis of major regulations in the field of food safety is made, including in the implementation of sanitary and epidemiological surveillance. The necessity of the expansion of measures to improve the statistics of food poisoning is grounded. The basic reasons for the spread of management practices of production and sale of food products that pose a threat to human life are revealed. The factors of unhindered penetration of local markets in the cities and the surrounding countrysides with counterfeiting, smuggling and production of global junk food manufacturers and consumer goods are defined. A systematic view is put on the problems of food production in the private farms, ways to limit direct access to the market of food and food raw materials, which production was not controlled and who have not passed state registration, are suggested. One of these problems is creation of independent industrial structures that link production and sales of small-scale sector goods.

    Medication errors most commonly occur at the time of medication prescribing and particularly at the moment of the transitions of care. The objectives of this study were to identify and characterize the discrepancies between the physicians' discharge medication orders and the medication lists at admission obtained by an internal medicine specialist physician in a general internal medicine service. This descriptive, retrospective, study was carried out at a tertiary care university teaching hospital in Spain. It was based on the review of non selected, consecutive, hospital discharge reports. Discrepancies were identified, categorized and characterized through the analysis of the information (medication lists, laboratory tests results, diagnosis, and clinical evolution) contained in them. We analyzed 954 discharge reports. In the medication reconciliation process, we find discrepancies in 832 (87.2%) of them. Justified discrepancies were found in 828 (86.8%) reports and unjustified discrepancies in 52 (5.4%). Omission of a medication was the most frequent medication error detected in 86.4% of cases, followed by incomplete prescription (9.6%). The number of diagnosis, the length of hospital stay and the number of permanent medications at admission were the characteristics of cases associated with medication discrepancies in multivariate linear regression (Pmedication errors detected in our study. Appropriate routines to ensure an accurate medication history collection and a methodical elaboration of the medication list at discharge, when performed by trained internists, are important for an adequate medication reconciliation process.

    Introduction Leg length discrepancy (LLD) causes pelvic obliquity in the frontal plane and lumbar scoliosis with convexity towards the shorter extremity. Leg length discrepancy is observed in 3-15% of the population. Unequalized lower limb length discrepancy leads to posture deformation, gait asymmetry, low back pain and discopathy. Material and methods In the years 1998-2006, 369 children, aged 5 to 17 years (209 girls, 160 boys) with LLD-related functional scoliosis were treated. An external or internal shoe lift was applied. Results Among 369 children the discrepancy of 0.5 cm was observed in 27, 1 cm in 329, 1.5 cm in 9 and 2 cm in 4 children. During the first follow-up examination, within 2 weeks, the adjustment of the spine to new static conditions was noted and correction of the curve in 316 examined children (83.7%). In 53 children (14.7%) the correction was observed later and was accompanied by slight low back pain. The time needed for real equalization of limbs was 3 to 24 months. The time needed for real equalization of the discrepancy was 11.3 months. Conclusions Leg length discrepancy equalization results in elimination of scoliosis. Leg length discrepancy < 2 cm is a static disorder; that is why measurements should be performed in a standing position using blocks of adequate thickness and the position of the posterior superior iliac spine should be estimated.

    Reproductive division of labour is a characteristic trait of social insects. The dominant reproductive individual, often the queen, uses chemical communication and/or behaviour to maintain her social status. Queens of many social insects communicate their fertility status via cuticle-bound substances. As these substances usually possess a low volatility, their range in queen-worker communication is potentially limited. Here, we investigate the range and impact of behavioural and chemical queen signals on workers of the ant Temnothorax longispinosus. We compared the behaviour and ovary development of workers subjected to three different treatments: workers with direct chemical and physical contact to the queen, those solely under the influence of volatile queen substances and those entirely separated from the queen. In addition to short-ranged queen signals preventing ovary development in workers, we discovered a novel secondary pathway influencing worker behaviour. Workers with no physical contact to the queen, but exposed to volatile substances, started to develop their ovaries, but did not change their behaviour compared to workers in direct contact to the queen. In contrast, workers in queen-separated groups showed both increased ovary development and aggressive dominance interactions. We conclude that T. longispinosus queens influence worker ovary development and behaviour via two independent signals, both ensuring social harmony within the colony.

    Over 25 million people in the USA have limited English proficiency (LEP). Interpreters are often used to facilitate communication with health care providers. Little is currently known about interpreter quality. To explore the quality of telephone interpretation during medication consultations between Hmong clients and their pharmacists. This descriptive study analyzed transcripts from videos of consultations between six triads of Hmong patients, pharmacy students and interpreters. Analysis was divided into two segments: (1) pharmacy: communication from student pharmacist the interpreter to patient and (2) patient: communication from patient to interpreter to student pharmacist. Researchers coded transcripts separately then compared codes. The six encounters yielded 496 communications with 275 discrepancies including omissions, additions, and word substitutions. Pharmacy to patient communications included, 45% (118/262) of omissions, 27.5% (72/262) of substitutions, and 15.6% (41/262) of additions. The patient to provider communications included, 8.1% (19/234) of omissions, 6.0% (14/234) of substitutions, and 4.2% (10/234) of word additions. Some omissions, additions, and substitutions in the pharmacy to patient communications were classified as potentially clinically relevant. Significantly, substantial discrepancies between the student pharmacists' comments and the interpretation to patients had potential for hindering relationship building between patients and their providers. Pharmacists may assume that the presence of an interpreter ensures accurate communication from pharmacist to patient and from patient to pharmacist. This study confirms that those assumptions may not be valid. These findings highlight the need to improve pharmacy education and interventions to improve pharmacist communication with LEP patients. © 2015 Royal Pharmaceutical Society.

    Full Text Available The purpose of this research was to reveal the level of implementation of authentic assessment in the pragmatics course at the English Education Department of a university. Discrepancy Evaluation Model (DEM was used. The instruments were questionnaire, documentation, and observation. The result of the research shows that respectively, the effectiveness of definition, installation, process, and production stages in logits are -0.06, -0.14, 0.45, and 0.02 on its aspect of the assessment methods’ effectiveness in uncovering students’ ability. Such values indicate that the level of implementation fell respectively into ‘very high’,’high’, ‘low’, and ‘very low’ categories.  The students’ success rate is in ‘very high’ category with the average score of 3.22. However, the overall implementation of the authentic assessment fell into a ‘low’ category with the average score of 0.06. Discrepancies leading to such a low implementation are the unavailability of the assessment scheme, that of scoring rubric, minimal (only 54.54% diversification of assessment methods, infrequency of the lecturer’s feedback on the students’ academic achievement, and the non-use of portfolio assessment.

    2014-01-01

    © 2014 Society for Industrial and Applied Mathematics. We propose the use of the Kantorovich-Rubinstein norm from optimal transport in imaging problems. In particular, we discuss a variational regularization model endowed with a Kantorovich- Rubinstein discrepancy term and total variation regularization in the context of image denoising and cartoon-texture decomposition. We point out connections of this approach to several other recently proposed methods such as total generalized variation and norms capturing oscillating patterns. We also show that the respective optimization problem can be turned into a convex-concave saddle point problem with simple constraints and hence can be solved by standard tools. Numerical examples exhibit interesting features and favorable performance for denoising and cartoon-texture decomposition.

  1. Phase coupling gravity and astronomical mass discrepancies

    International Nuclear Information System (INIS)

    Sanders, R.H.

    1988-01-01

    A previous author has proposed a new theory of gravity in which an additional long-range force is associated with a complex scalar field. The unique aspect of the theory is that only the phase of the complex scalar field couples to matter; hence, the designation 'phase coupling gravity'. The scalar field Lagrangian density contains a self-interaction potential which, in original form, depends upon the sixth power of the scalar amplitude because then the resulting weak field phenomenology is similar to that of MOND, the empirically motivated modification of Newton's law in the limit of low accelerations previously suggested in order to account for the observed mass discrepancies in large astronomical systems. In the present paper I explore versions of phase coupling gravity with alternative forms for the scalar self-interaction. (author)

  2. Discrepancy between Clambda and Csub(E)

    International Nuclear Information System (INIS)

    Williams, P.C.

    1977-01-01

    The conversion factors Clambda and Csub(E) are used in relating ionization chamber readings (M) to absorbed dose in water for measurements made in phantoms irradiated with photons of quality lambda and electrons of mean energy - E respectively. New calculations of Clambda (Nahum, A.E., and Greening, J.R., 1976, Phys. Med. Biol., vol.21, 862) have yielded values which differ by up to 5% from those quoted by ICRU (ICRU, 1969, Report 14, ICRU Publications, P.O. Box 30165, Washington, DC 20014). Nahum and Greening have also pointed out that the recommended values of Clambda and Csub(E) for radiations of approximately the same primary electron energy should be the same, but differ by approximately 4%. Alternative explanations are offered for these discrepancies. If the ICRU values are corrected for the perturbation of the electron flux in the phantom by the introduction of a cavity, the ionization chamber, into the phantom, then the resulting values are in good agreement with those quoted by Nahum and Greening. The discrepancy between Clambda and Csub(E) is the result of inconsistent definitions. The ICRU definition of Csub(E) leads to a dose conversion factor which is dimensionally correct but is based on the assumption that the product M.Nsub(c), where Nsub(c) is the exposure calibration factor for the ionization chamber at the calibration quality, 2MV, can be identified as exposure, whereas this is only true at the calibration quality. More accurate definitions of Clambda and Csub(E) are therefore proposed. (U.K.)

    Bernard, Mark M; Gebauer, Jochen E; Maio, Gregory R

    2006-01-01

    Study 1 examined whether cultural estrangement arises from discrepancies between personal and societal values (e.g., freedom) rather than from discrepancies in attitudes toward political (e.g., censorship) or mundane (e.g., pizza) objects. The relations between different types of value discrepancies, estrangement, subjective well-being, and need for uniqueness also were examined. Results indicated that personal-societal discrepancies in values and political attitudes predicted estrangement, whereas mundane attitude discrepancies were not related to estrangement. As expected, value discrepancies were the most powerful predictor of estrangement. Value discrepancies were not related to subjective well-being but fulfilled a need for uniqueness. Study 2 replicated the relations between value discrepancies, subjective well-being, and need for uniqueness while showing that a self-report measure of participants' values and a peer-report measure of the participants' values yielded the same pattern of value discrepancies. Together, the studies reveal theoretical and empirical benefits of conceptualizing cultural estrangement in terms of value discrepancies.

    Full Text Available The aim of the systematic ensuring of knowledge continuity is the continuity of an organisation’s development, the quality of managerial positions and the continuity of decision-making. By ensuring knowledge continuity, organisations may gain a performance-enhancing factor. The objective of the article is to identify the level of impact of decisive internal factors determining knowledge continuity ensuring and contributing to the efficiency of the organisations. Knowledge continuity ensuring as an internal force, however, can together with the right employees, help adapt more quickly to external conditions that organisations can hardly control. Monitoring and ensuring knowledge continuity can contribute to a higher quality of processes in general, in particular processes exploiting knowledge, and thus help improve the level of management. The first part of the article presents theoretical views on the aspects of knowledge continuity ensuring in organisations while the second part analyses the findings of the surveys carried out among managers in organisations in the Czech Republic. Based on the summary of the outcomes obtained it is possible to say that internal factors influence knowledge continuity ensuring in organisations, however, the level of impact of individual factors is determined by their size. The findings regarding the impact of each of the factors show that the most significant barriers to knowledge continuity ensuring are those associated with the human factor.

  9. Discrepancy between mRNA and protein abundance: insight from information retrieval process in computers.

    2008-12-01

    Discrepancy between the abundance of cognate protein and RNA molecules is frequently observed. A theoretical understanding of this discrepancy remains elusive, and it is frequently described as surprises and/or technical difficulties in the literature. Protein and RNA represent different steps of the multi-stepped cellular genetic information flow process, in which they are dynamically produced and degraded. This paper explores a comparison with a similar process in computers-multi-step information flow from storage level to the execution level. Functional similarities can be found in almost every facet of the retrieval process. Firstly, common architecture is shared, as the ribonome (RNA space) and the proteome (protein space) are functionally similar to the computer primary memory and the computer cache memory, respectively. Secondly, the retrieval process functions, in both systems, to support the operation of dynamic networks-biochemical regulatory networks in cells and, in computers, the virtual networks (of CPU instructions) that the CPU travels through while executing computer programs. Moreover, many regulatory techniques are implemented in computers at each step of the information retrieval process, with a goal of optimizing system performance. Cellular counterparts can be easily identified for these regulatory techniques. In other words, this comparative study attempted to utilize theoretical insight from computer system design principles as catalysis to sketch an integrative view of the gene expression process, that is, how it functions to ensure efficient operation of the overall cellular regulatory network. In context of this bird's-eye view, discrepancy between protein and RNA abundance became a logical observation one would expect. It was suggested that this discrepancy, when interpreted in the context of system operation, serves as a potential source of information to decipher regulatory logics underneath biochemical network operation.

    Full Text Available Objectives: The relationship between the presence of bone defects (fenestrations and dehiscences observed in lateral slices in computerized axial tomography (CAT images and maxillomandibular transverse discrepancies was determined. Methods: The sample was composed of 160 CAT scan files, corresponding to 9-25-year-old patients, which had been taken prior to orthodontic treatment at a radiology center in Guadalajara, México, from 2009 to 2012. They were grouped by age, and we identified bone defects in maxillary teeth (first and second premolars and first molars. The maxillary (JL-JR and mandibular (GA-AG widths were measured, and the maxillomandibular discrepancy ([GA-AG]-[JL-JR] was calculated. Chi-square and t-tests were performed. Results: The values of maxillomandibular discrepancies increased with the age of the patient. There was no association between the magnitude of the maxillomandibular discrepancy and the presence of bone defects. The gender of the individual was not a decisive factor in whether bone defects were present. Conclusion: Bone defects occur in the vast majority of patients pretreatment regardless of the magnitude of the maxillomandibular discrepancy.

    The energy of a system which is described by a Hamiltonian which includes at most two-particle interactions can be expressed in terms of the second order reduced density matrix. However, for the 2-matrix to have proper symmetry is a weaker condition than requiring that the wavefunction be antisymmetric, which is called the N-representability problem, a problem of long term interest. Coleman [Reduced Density Matrices: Coulson's Challenge, Springer, New York, 2000] however, proposed an algorithm which ensures N-representability. In this Letter we examine the algorithm and show its connection to the full configuration interaction method and the contracted Schroedinger equation.

  17. Attempt to explain the uranium 238 resonance integral discrepancy

    For light water reactor physics, studies on uranium 238 resonance integral discrepancy were carried out. It was shown that using recently published resonance parameters and substituting a multilevel formalism to the usual Breit and Wigner formula reduced the well known discrepancy between two values of the uranium 238 effective resonance integral: the value calculated with the nuclear data and the one deduced from critical experiments. Since the cross section computed with these assumptions agrees quite well with the Oak Ridge transmission data, it was used to obtain the self-shielding effect and the capture rate in light water lattices. The multiplication factor calculated with this method is found very close to the experimental value. Preliminary results for a set of benchmarks relative to several types of thermal neutron reactors lead to very low discrepancies. The reactivity loss is only 130 x 10 -5 instead of 650 x 10 -5 in the case of the usual libraries and the single level formula

    Self-discrepancy describes the distance between an ideal and the actual self. Research suggests that self-discrepancy and dietary restraint are related, causing a significant impact on the person's well-being. However, this relationship has been mostly reported in female and mixed populations. In order to further explore dietary behaviors and their relations to self-discrepancy and well-being-related variables in men, a survey was applied to a non-probabilistic sample of 119 male students from five Chilean state universities (mean age=21.8, SD=2.75). The questionnaire included the Revised Restraint Scale (RRS) with the subscales weight fluctuations (WF) and diet concern (DC), the Satisfaction with Life Scale (SWLS), the Satisfaction with Food-Related Life Scale (SWFL), the Nutrition Interest Scale (NIS), and the Self-discrepancy Index (SDI). Questions were asked about socio-demographic characteristics, eating and drinking habits, and approximate weight and height. A cluster analysis applied to the Z-scores of the RRS classified the following typologies: Group 1 (22.7%), men concerned about weight fluctuations; Group 2 (37.0%), men concerned about diet and weight fluctuations; Group 3 (40.3%), unconcerned about diet and weight fluctuations. The typologies differed in their SDI score, restriction on pastry consumption and reported body mass index (BMI). Students with higher DC and WF scores had a higher BMI, and tended to report high self-discrepancy not only on a physical level, but also on social, emotional, economic and personal levels. This study contributes to the literature on subjective well-being, dietary restraint and self-discrepancy in men from non-clinical samples. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A current medication plan was identified as important patient safety factor. Information is needed on how many patients possess such a plan and what problems can be identified with its use. This study tried to define factors that influence accuracy of medication plans and to detect discrepancies from planned and actually administered medication in polypharmacy patients. Participants of the 'Apo-AMTS' course in Germany evaluated medication plans from their patients during performing medication reviews in community pharmacies. Discrepancies were defined as additional or missing drugs and deviations in dosage and drug names for Rx drugs and missing or additional self-medication. Eighty per cent of the patients possessed a medication plan mainly written by general practitioners. Only 6.5% of the plans showed no discrepancies. Most discrepancies were seen on medication plans written by medical specialists and general practitioners, mainly name aberrations (41%) followed by additional drugs taken (30%) and prescribed drugs no longer taken (18%). Dosage variance was seen in 11% of all discrepancies. Deviations from the plan were observed frequently with antihypertensives (31.4%), analgesics (11.3%) and antidepressants/hypnotics as well as lipid-lowering drugs (6.7%). Four hundred thirty-three OTC drugs were not listed, mainly analgesics, mineral supplements and laxatives. Many patients possess a medication plan but most of these plans showed discrepancies which limits the use as patient safety indicator. Community pharmacies offering medication reviews have an essential position to use the medication plan as a central link between patients and their prescribers, and therefore improve patient safety. © 2015 John Wiley & Sons, Ltd.

    Ancilla Systems, Inc., Elk Grove Village, Il, developed a mission-based performance evaluation program to provide tangible evidence of mission fulfillment and ensure the provision of high-quality healthcare. the program--Characteristics of Service--translates the language of healthcare action and evaluates corporate culture to ensure that it fulfills the expectations of its sponsor. The nine Characteristics of Service are: Respect for the dignity of all persons. Orientation toward the family unit. Quality and personalized services. Local health systems with a spectrum of services responsive to the unique needs of the community. Formal and informal partnerships with physicians. Active participation and collaboration with related community service agencies and other healthcare providers. Faithfulness to Catholic identity through close relationships with Church and religious institute resources. Effective political advocacy through education. Research and development of innovative approaches to healthcare. In establishing the behavior standards that would exemplify the characteristics, program developers used terms that correspond to specific, observable, measurable performance. All healthcare facilities are evaluated on how well they meet the behavior standards. The evaluation process includes data collection, analysis, and a final report. Data collection begins with a review of regular hospital-conducted surveys, which provide quantifiable information to measure performance against key expected behaviors. Additional data are derived from medical staff development plans and the monthly quality assurance audit. On-site surveys fill information gaps that remain after all written reports are collected.

    Every pediatrician would want to satisfy their patients and their parents to sustain good practice, earn name and fame and simultaneously to avoid litigation in this era of consumer protection act. This can be achieved only by use of good communication skills. Today the patients demand time, information and want their questions to be answered. They expect politeness, empathy and human touch from doctors. Time constraints, arrogance, telephone calls, language barriers and cultural insensitivity are the important barriers to good communication. Research has shown that doctor, who undergoes training to acquire good communication skills, can better satisfy his patients. Good communication skill is an art which can be acquired or improved by putting conscious efforts in day to day practice. Such skills should also be incorporated as part of medical teaching curriculum. Asking open ended questions, effective listening, appropriate praise, providing enough information as part of advice and finally checking their understanding, are the key areas of communication during medical interview. During this process pediatrician should ensure to address the parental concerns, should empathize with parents and involve parents in decision making. This will not only ensure satisfaction of parents but also their adherence to the therapy and to the pediatrician.

    Full Text Available Relevance of the topic is determined by the need for sustainable development of the country’s banking system, capable of ensuring the process of raising funds to producers and the public for their projects. One of the implementation of this objective is to discourage unfair behavior in financial markets. Trust is a key factor in the development of financial markets, therefore it is necessary to suppress the appearance of unfair practices and participants – black creditors, falsification of financial statements, trading on insider information and market manipulation. It requires a whole range of activities, and above all ensuring the inevitability and proportionality of punishment for unscrupulous players, the introduction of requirements for the business reputation of the management of financial institutions.The article is devoted to structuring legal violations in the lending sphere. The analysis of indicators of credit organizations in Russia was conducted to fulfill this aim. This analysis revealed the causes of sustainable growth of overdue accounts payable – job cuts in enterprises, violations in the financial sector, various errors in the credit granting / raising. The authors carry out the systematization and classification of offenses in the area of lending, provide examples, as well as factual material illustrating the violations in the lending process having the characteristics of a fraud. The article substantiates the obligations of employees of the credit institution, in the result of which risks of granting credit to fraudsters can be reduced. The methods of fraud prevention should include the identified methods of protection against fraud in the area under consideration – exchange of information by banks associated with the criminal intentions of customers; technology development and technical support, training, and personnel responsibilities.

    The research in this thesis focuses on the impacts of and adaptation to present variations in climate and to projected future changes. The research has dealt with different levels, i.e. household/community, national/policymaking, and sectoral level, to show different perspectives of the implications of climate variability and change to development. In particular, it focuses on how present variations in rainfall patterns affect rural households, ways to strengthen households' resilience to climate variability, and the costs and benefits of adaptation measures. The research attempts to contribute to the knowledge that informs the development community and national governments for policy-making on the implications of climate change on development planning and strategies. It is argued in the thesis that it is essential for sustainable development to mainstream climate change into strategies and planning where relevant. To do this a knowledge of the costs and benefits of diverse adaptation measures is essential. Fluctuations in annual and seasonal rainfall, both in terms of modest and excessive rains, are found to cause negative shocks to rural household incomes in the Kagera a region of Tanzania. An analysis of rainfall and household data for the region shows large local discrepancies in the distribution of rainfall, as well as in households reporting shocks to income caused by harvest failure. It is also evident from the research results that the timing of rainfall seems to play a greater role than the level of annual precipitation. The coping strategies that households report following subsequent to a harvest failure further show local divergence in the choice of, for example, taking casual employment and relying on support from others in the form of informal networks. These results support earlier work which points in the same direction and emphasizes that policies should be targeted to local specificities. This provides a great motivation for targeted

    2017-02-01

    Errors and discrepancies in radiology practice are uncomfortably common, with an estimated day-to-day rate of 3-5% of studies reported, and much higher rates reported in many targeted studies. Nonetheless, the meaning of the terms "error" and "discrepancy" and the relationship to medical negligence are frequently misunderstood. This review outlines the incidence of such events, the ways they can be categorized to aid understanding, and potential contributing factors, both human- and system-based. Possible strategies to minimise error are considered, along with the means of dealing with perceived underperformance when it is identified. The inevitability of imperfection is explained, while the importance of striving to minimise such imperfection is emphasised. • Discrepancies between radiology reports and subsequent patient outcomes are not inevitably errors. • Radiologist reporting performance cannot be perfect, and some errors are inevitable. • Error or discrepancy in radiology reporting does not equate negligence. • Radiologist errors occur for many reasons, both human- and system-derived. • Strategies exist to minimise error causes and to learn from errors made.

    Selective outcome reporting of either interesting or positive research findings is problematic, running the risk of poorly-informed treatment decisions. We aimed to assess the extent of outcome and other discrepancies and possible selective reporting between registry entries and published reports among leading medical journals. Randomized controlled trials published over a 6-month period from July to December 31st, 2013, were identified in five high impact medical journals: The Lancet, British Medical Journal, New England Journal of Medicine, Annals of Internal Medicine and Journal of American Medical Association were obtained. Discrepancies between published studies and registry entries were identified and related to factors including registration timing, source of funding and presence of statistically significant results. Over the 6-month period, 137 RCTs were found. Of these, 18% (n = 25) had discrepancies related to primary outcomes with the primary outcome changed in 15% (n = 20). Moreover, differences relating to non-primary outcomes were found in 64% (n = 87) with both omission of pre-specified non-primary outcomes (39%) and introduction of new non-primary outcomes (44%) common. No relationship between primary or non-primary outcome change and registration timing (prospective or retrospective; P = 0.11), source of funding (P = 0.92) and presence of statistically significant results (P = 0.92) was found. Discrepancies between registry entries and published articles for primary and non-primary outcomes were common among trials published in leading medical journals. Novel approaches are required to address this problem.

    the operability of the machine and tractor aggregates is ensured by processes which occur in machine units and considered as technical systems. In order to develop theoretical understanding of the processes in technical systems as the basis and purpose of the repairserving actions, the author's concept is presented which relies on on the basic concepts of "processes in technical systems", "maintenance and repair of performers", "maintenance and repair of technology" "objectives of the maintenance and repair". Analysis of the basic concepts of "processes in technical systems" made possible to distinguishing four types of relations: of order, stipulation, exactingness, and non-contradiction. It is shown that the implementation of maintenance and repair of technology should be conducted according to the assessment of the effectiveness of processes in technical systems, revealed in complex diagnosis. The perfection of the design of the machine in terms of its technical operation can be estimated according to the degree of consistency of processes in technical systems, purposes of maintenance and repair. In order to increase the efficiency of the lubrication system,the modernised design of the centrifugal oil filter with permanent control of its cleaning power is offered, which allows changing the technology of the maintenance of engine lubrication system by separating the operations of crankcase oil replacement and the rotor filter cleaning.

  16. Surgical treatment for obesity: ensuring success.

    Andris, Deborah A

    2005-01-01

    In the United States, obesity has reached epidemic proportions. Serious medical complications, impaired quality of life, and premature mortality are all associated with obesity. Medical conditions such as type 2 diabetes mellitus, hypertension, hyperlipidemia, or sleep apnea can improve or be cured with weight loss. Medical treatment programs focused on diet, behavior modification, and/or pharmacologic intervention have met with limited long-term success. Although surgical treatments for obesity have become popular in recent years, they should only be used as a last resort for weight loss. Not all patients can be considered appropriate candidates for surgery; therefore, guidelines based on criteria from the National Institutes of Health should be used preoperatively to help identify suitable persons. Most individuals who opt for weight-loss surgery have usually struggled for many years with losing weight and keeping it off, but surgery alone will not ensure successful weight loss. Patient education is imperative for long-term success. Moreover, any such educational regimen should include information on diet, vitamin and mineral supplementation, and lifestyle changes, as well as expected weight-loss results and improvements in comorbid conditions. Patients must be willing to commit to a long-term follow-up program intended to promote successful weight loss and weight maintenance and to prevent metabolic and nutritional complications.

    The aim of this study was to evaluate professional socialization of nurses and its association with assurance of practice activity. The study was carried out in randomly selected Lithuanian health care institutions from January to June 2007. A total of 1300 nurses, enrolled in the study, were divided into three groups according to the position held by participants: general practice nurses, 77.8%; senior nurses and leaders, 10.7%; and 4th-year students of general nurse education program, 11.5%. A questionnaire-based survey was carried out. The data were processed with SPSS 15.0 statistical software. Descriptive and multidimensional statistical methods were applied in the study. The matrix model, integrating characteristics of nurses' professional socialization and dimensions of practice activity and disclosing parameters and indicators of assurance of these processes, was applied for data analysis. The respondents favorably evaluated the aspects ensuring professional socialization and practice activity such as "professional activity," "motivators of professional activity," "professional characteristic," "system of professional values," and "professional behavior." The respondents unfavorably evaluated the following parameters: "security of professional self-expression and self-education," "professional development," "professional expectations," and "implementation of institution strategies." For the evaluation of nurses' professional socialization and practice activity, a theoretical model was created, and nine diagnostic criteria, integrating the characteristics of professional socialization and dimensions of practice activity, were formulated. A significant positive correlation was determined among the majority of the diagnostic criteria of the intercorrelation matrix of theoretical model. Having summarized the attitude of nurses toward professional socialization and the provision of practice activity, both favorable and unfavorable aspects of assessment

    According to Harter (1985a), global self-worth (GSW) can be predicted from the relationship between perceptions of competence and importance ratings. In this study, we employed Harter's (1985b) Importance Rating Scale (IRS) and Self-Perception Profile for Children (SPPC) to examine importance ratings, discrepancy scores, and domain-specific perceptions of competence as predictors of GSW. Children (N = 130, 62 boys and 68 girls) aged 8-12 years were categorized into high (HMC; n = 62) and low motor coordination (LMC; n = 68) groups according to their scores on a motor proficiency battery (McCarron, 1982). Regression analyses using domain-specific perceptions of competence, importance, and discrepancy scores confirmed that self-perception ratings were the best predictors of GSW. For both groups, perceptions of physical appearance, social acceptance, and behavioral conduct contributed significantly to prediction of GSW. By contrast, perceived athletic competence increased prediction of GSW for the HMC group but not the LMC group.

    2016-01-01

    Both classical social psychological theories and recent formal models of opinion differentiation and bi-polarization assign a prominent role to negative social influence. Negative influence is defined as shifts away from the opinion of others and hypothesized to be induced by discrepancy with or disliking of the source of influence. There is strong empirical support for the presence of positive social influence (a shift towards the opinion of others), but evidence that large opinion differences or disliking could trigger negative shifts is mixed. We examine positive and negative influence with controlled exposure to opinions of other individuals in one experiment and with opinion exchange in another study. Results confirm that similarities induce attraction, but results do not support that discrepancy or disliking entails negative influence. Instead, our findings suggest a robust positive linear relationship between opinion distance and opinion shifts.

    Full Text Available Objective: To determine the prevalence of tooth size discrepancy (TSD in a representative orthodontics population, to explore how many millimeters of TSD is clinically significant and to determine the ability of simple visual inspection to detect such a discrepancy. Materials and Methods: The sample comprised 150 pretreatment study casts with fully erupted and complete permanent dentitions from first molar to first molar, which were selected randomly from records of the orthodontic patients. The mesiodistal diameters of the teeth were measured at contact points using digital calipers and the Bolton′s analysis was carried out on them. Simple visual estimation of Bolton discrepancy was also performed. Results: In the sample group, 24% of the patients had anterior tooth width ratios and 8% had total arch ratios greater than ±2 standard deviation (SD from Bolton′s means. For the anterior analysis, correction greater than ±2 mm was required for 24% of patients in the upper arch or 14% in the lower arch. For the total arch analysis, correction greater than ±2 mm was required for 36% of patients in the upper arch or 32% in the lower arch. Conclusion: Bolton′s analysis should be routinely performed in all orthodontic patients and the findings should be included in orthodontic treatment planning. 2 mm of the required tooth size correction is an appropriate threshold for clinical significance. Visual estimation of TSD has low sensitivity and specificity. Careful measurement is more frequently required in clinical practice than visual estimation would suggest.

    process; and the reductions in wind tunnel testing requirements within the largest consumer of ATP wind tunnel test time, the Aeronautics Research Mission Directorate (ARMD). Retirement of the Space Shuttle Program and recent perturbations of NASA's Constellation Program will exacerbate this downward trend. Therefore it is crucial that ATP periodically revisit and determine which of its test capabilities are strategically important, which qualify as low-risk redundancies that could be put in an inactive status or closed, and address the challenges associated with both sustainment and improvements to the test capabilities that must remain active. This presentation will provide an overview of the ATP vision, mission, and goals as well as the challenges and opportunities the program is facing both today and in the future. We will discuss the strategy ATP is taking over the next five years to address the National aeronautics test capability challenges and what the program will do to capitalize on its opportunities to ensure a ready, robust and relevant portfolio of National aeronautics test capabilities.

    In B(A) phenotype, an autosomal dominant phenotype, there is a weak A expression on group B RBCs. We herein report a case of a probable B(A) phenotype in a first time 20-year old male donor. The cell and serum grouping were done using tube technique and also with blood grouping gel card (Diaclone, ABD cards for donors, BioRad, Switzerland). The antisera used were commercial monoclonal IgM type. To check for the weak subgroup of A, cold adsorption and heat elution was performed. The cell grouping was A weak B RhD positive while the serum grouping was B. There was no agglutination with O cells and the autologous control was also negative. It was a group II ABO discrepancy with or without group IV discrepancy. Results for both the eluate and last wash were negative. Hence, the possibility of weak subgroup of A was unlikely. Blood grouping gel card also showed a negative reaction in the anti-A column. One lot of anti-A was showing 'weak +' agglutination while the other lot was showing 'negative' reaction with the donor RBCs by tube technique. There was no agglutination observed with anti-A1 lectin. Our case highlights the serological characteristics of a B(A) phenotype. This case emphasizes the vital role of cell and serum grouping in detecting such discrepancies especially in donors which can lead to mislabeling of the blood unit and may be a potential risk for the transfusion recipient if not resolved appropriately.

    2017-12-01

    Compilations of well-resolved oceanic residual depth measurements suggest that present-day dynamic topography differs from that predicted by geodynamic simulations in two significant respects. At short wavelengths (λ ≤ 5,000 km), much larger amplitude variations are observed, whereas at long wavelengths (λ > 5,000 km), observed dynamic topography is substantially smaller. Explaining the cause of this discrepancy with a view to reconciling these different approaches is central to constraining the structure and dynamics of the deep Earth. Here, we first convert shear wave velocity to temperature using an experimentally-derived anelasticity model. This relationship is calibrated using a pressure and temperature-dependent plate model that satisfies age-depth subsidence, heat flow measurements, and seismological constraints on the depth to the lithosphere-asthenosphere boundary. In this way, we show that, at short-wavelengths, observed dynamic topography is consistent with ±150 ºC asthenospheric temperature anomalies. These inferred thermal buoyancy variations are independently verified by temperature measurements derived from geochemical analyses of mid-ocean ridge basalts. Viscosity profiles derived from the anelasticity model suggest that the asthenosphere has an average viscosity that is two orders of magnitude lower than that of the underlying upper mantle. The base of this low-viscosity layer coincides with a peak in azimuthal anisotropy observed in recent seismic experiments. This agreement implies that lateral asthenospheric flow is rapid with respect to the underlying upper mantle. We conclude that improved density and viscosity models of the uppermost mantle, which combine a more comprehensive physical description of the lithosphere-asthenosphere system with recent seismic tomographic models, can help to resolve spectral discrepancies between observed and predicted dynamic topography. Finally, we explore possible solutions to the long

  5. A reflection on radiographic cephalometry: the evaluation of sagittal discrepancy.

    2014-09-01

    A critical review is presented of the basic properties and applications of cephalometry as a clinical tool with a focus on the evaluation of sagittal discrepancy. Diagnostic cephalometric assessments are subjective and not based on evidence. To assess individual skeletal and/or facial soft tissue form subjectively, selected norms are used. Norms have been developed for various ethnical groups to improve clinical applicability, but subjectivity remains. That subjectivity precludes application of a modern review system, making the present review a personal account. The cephalometric evaluation of sagittal discrepancy finds its historic origin in the Angle classification. Recent publications try to improve accuracy in classifying sagittal discrepancy. It remains unclear in what sense such efforts influence treatment decisions and/or treatment effect. Almost all selected landmarks are located on or dependent upon periosteal/endosteal bone image contours. Their homology is based on circumstantial reasoning and stability over time, which is implicitly assumed. However, implant growth studies and histological investigations show most landmarks to be unstable, as they are involved in displacement and bone remodelling. These landmarks are therefore heterologous when used for individual evaluation of change over time. Notwithstanding the above-indicated limitations, diagnostic cephalometric assessments are clinically useful and help to develop perceptions of balance and harmony and communication between colleagues and patients. There is no evidence-based method to prefer one particular diagnostic method. Landmark location accuracy and geometric issues do not play a decisive role. The subjective characteristic of diagnostic evaluations limits their power to size/shape comparisons. Structural superimposition is the valid biologically evidence-based method to provide advanced insight in individual growth and/or treatment changes and their variations. © 2014 British Orthodontic

    Ehrlich, Katherine B.; Cassidy, Jude; Dykas, Matthew J.

    2010-01-01

    The issue of informant discrepancies about child and adolescent functioning is an important concern for clinicians, developmental psychologists, and others who must consider ways of handling discrepant reports of information, but reasons for discrepancies in reports have been poorly understood. Adolescent attachment and informant depressive symptoms were examined as two explanations for absolute and directional discrepancies about adolescent symptoms, relationships, and social behavior in a sample of 189 eleventh-grade students (mean age = 16.5 years). Adolescent attachment predicted absolute discrepancies, with greater attachment coherence associated with fewer discrepancies in reports of adolescent depressive symptoms, parent-adolescent conflict, and adolescent externalizing behavior. Parents’ but not adolescents’ depressive symptoms sometimes predicted absolute discrepancies. Mothers’ depressive symptoms and adolescent attachment predicted the direction of discrepancies for mother-peer reports only. PMID:21410916

    Scientific literature can contain errors. Discrepancies, defined as two or more statements or results that cannot both be true, may be a signal of problems with a trial report. In this study, we report how many discrepancies are detected by a large panel of readers examining a trial report containing a large number of discrepancies. We approached a convenience sample of 343 journal readers in seven countries, and invited them in person to participate in a study. They were asked to examine the tables and figures of one published article for discrepancies. 260 participants agreed, ranging from medical students to professors. The discrepancies they identified were tabulated and counted. There were 39 different discrepancies identified. We evaluated the probability of discrepancy identification, and whether more time spent or greater participant experience as academic authors improved the ability to detect discrepancies. Overall, 95.3% of discrepancies were missed. Most participants (62%) were unable to find any discrepancies. Only 11.5% noticed more than 10% of the discrepancies. More discrepancies were noted by participants who spent more time on the task (Spearman's ρ = 0.22, P < 0.01), and those with more experience of publishing papers (Spearman's ρ = 0.13 with number of publications, P = 0.04). Noticing discrepancies is difficult. Most readers miss most discrepancies even when asked specifically to look for them. The probability of a discrepancy evading an individual sensitized reader is 95%, making it important that, when problems are identified after publication, readers are able to communicate with each other. When made aware of discrepancies, the majority of readers support editorial action to correct the scientific record. © The Author 2015.

  17. Relationship of functional leg-length discrepancy to abnormal pronation.

    Science.gov (United States)

    Rothbart, Brian A

    2006-01-01

    The objective of this study was to determine whether a correlation exists between abnormal pronation and functional leg-length discrepancies. Visual assessment and a pelvic thrust maneuver were used to identify the functionally short leg in 56 indigenous Mexicans (20 males and 36 females; mean age, 33 years; mean weight, 59 kg; and mean height, 1.60 m). The Foot Posture Index was used with a modified stance position to identify the more pronated foot. The posterosuperior iliac spines were used to identify the "relative" position of the innominate bones. The raw data obtained from this study were evaluated using the McNemar test for paired proportions. A significant positive correlation was found between abnormal pronation and hip position and between hip position and functional leg-length discrepancy. These results are consistent with a theoretical ascending dysfunctional pelvic model: Abnormal pronation pulls the innominate bones anteriorly (forward); anterior rotation of the innominate bones shifts the acetabula posteriorly and cephalad (backward and upward); and this shift in the acetabula hyperextends the knees and shortens the legs, with the shortest leg corresponding to the most pronated foot.

  18. Exploration of Quantum Interference in Document Relevance Judgement Discrepancy

    2016-04-01

    Full Text Available Quantum theory has been applied in a number of fields outside physics, e.g., cognitive science and information retrieval (IR. Recently, it has been shown that quantum theory can subsume various key IR models into a single mathematical formalism of Hilbert vector spaces. While a series of quantum-inspired IR models has been proposed, limited effort has been devoted to verify the existence of the quantum-like phenomenon in real users’ information retrieval processes, from a real user study perspective. In this paper, we aim to explore and model the quantum interference in users’ relevance judgement about documents, caused by the presentation order of documents. A user study in the context of IR tasks have been carried out. The existence of the quantum interference is tested by the violation of the law of total probability and the validity of the order effect. Our main findings are: (1 there is an apparent judging discrepancy across different users and document presentation orders, and empirical data have violated the law of total probability; (2 most search trials recorded in the user study show the existence of the order effect, and the incompatible decision perspectives in the quantum question (QQ model are valid in some trials. We further explain the judgement discrepancy in more depth, in terms of four effects (comparison, unfamiliarity, attraction and repulsion and also analyse the dynamics of document relevance judgement in terms of the evolution of the information need subspace.

    The measurement of the cosmic microwave background has strongly constrained the cosmological parameters of the Universe. When the measured density of baryons (ordinary matter) is combined with standard Big Bang nucleosynthesis calculations, the amounts of hydrogen, helium and lithium produced shortly after the Big Bang can be predicted with unprecedented precision. The predicted primordial lithium abundance is a factor of two to three higher than the value measured in the atmospheres of old stars. With estimated errors of 10 to 25%, this cosmological lithium discrepancy seriously challenges our understanding of stellar physics, Big Bang nucleosynthesis or both. Certain modifications to nucleosynthesis have been proposed, but found experimentally not to be viable. Diffusion theory, however, predicts atmospheric abundances of stars to vary with time, which offers a possible explanation of the discrepancy. Here we report spectroscopic observations of stars in the metal-poor globular cluster NGC 6397 that reveal trends of atmospheric abundance with evolutionary stage for various elements. These element-specific trends are reproduced by stellar-evolution models with diffusion and turbulent mixing. We thus conclude that diffusion is predominantly responsible for the low apparent stellar lithium abundance in the atmospheres of old stars by transporting the lithium deep into the star.

  20. Discrepancies in normative data between Lunar and Hologic DXA systems.

    1996-01-01

    Many studies have shown the high correlation between Lunar and Hologic DXA bone mineral density (BMD) measurements despite differences in absolute calibration. However, in clinical practice, raw BMD values (in g/cm2) are not normally used for assessing skeletal status and fracture risk. Instead, the BMD values are expressed in terms of the number of standard deviations above or below the young normal value (commonly referred to as the T-score). If the normative populations of the various systems are consistent, the standard deviation scores should also be consistent. For this reason, the World Health Organization (WHO) recently established diagnostic criteria for osteoporosis based on T-scores and not BMD. However, few studies have compared the instruments in terms of their standard deviation scores. In this study, we used linear regression to compare T-scores in 83 women at L1-4 and 120 women at the femoral neck obtained on a Lunar DPX and a Hologic QDR-1000/W system. patient BMD and T-score measurements were highly correlated between the two systems (r > 0.95). No clinically significant difference in L1-4 T-scores was seen (less than 0.1 SD). However, linear regression analysis confirmed a systematic difference of 0.9 SD between the femoral neck T-scores. This discrepancy is caused by: (1) differences in the normal populations, and (2) differences in statistical models used to determine the young normal mean and standard deviation. In an attempt to correct the discrepancy, the female young normal mean and standard deviation were recalculated for the femoral neck using published epidemiological data from NHANES and existing DXA cross-calibration equations. The Hologic young normal value (mean +/- SD) was redefined as 0.85 +/- 0.11 g/cm2, while the Lunar value was redefined as 1.00 +/- 0.11 g/cm2. When the femoral neck T-scores for the study population were recalculated on the basis of these new values, the results were equivalent between manufactures, effectively

    To understand and ultimately prevent injury and behavioural health outcomes associated with masculinity, we assessed the influence of masculine discrepancy stress (stress that occurs when men perceive themselves as falling short of the traditional gender norms) on the propensity to engage in stereotypically masculine behaviours (eg, substance use, risk taking and violence) as a means of demonstrating masculinity. Six-hundred men from the USA were recruited via Amazon’s Mechanical Turk (MTurk) online data collection site to complete surveys assessing self-perceptions of gender role discrepancy and consequent discrepancy stress, substance use/abuse, driving while intoxicated (DWI) and violent assaults. Negative binomial regression analyses indicated significant interactive effects wherein men high on gender role discrepancy and attendant discrepancy stress reported significantly more assaults with a weapon (B=1.01; SE=0.63; IRR=2.74; p=0.05) and assaults causing injury (B=1.01; SE=0.51; IRR=2.74; p<0.05). There was no association of discrepancy stress to substance abuse, but there was a protective effect of gender role discrepancy for DWI among men low on discrepancy stress (B=−1.19, SE=0.48; IRR=0.30; p=0.01). These findings suggest that gender role discrepancy and associated discrepancy stress, in particular, represent important injury risk factors and that prevention of discrepancy stress may prevent acts of violence with the greatest consequences and costs to the victim, offender and society.

    Full Text Available The aim of this workshop and paper is to provide a conceptual framework that will develop skills in the areas of observation, cognition/meta-cognition with emphasis on critical thinking, decision making and problem solving. Simultaneously, this endeavour is designed to stimulate one‟s curiosity and thereby provide motivation to learn. These are accomplished through the learning style methodology with emphasis on interactive instructional resources addressing a multi-modality approach to teaching and learning. It will be shown that discrepant events impact thinking with respect to problem solving. The aforementioned is demonstrated with the use of gravity, molecular structure and optical illusions. The workshop presenters will show how cognitive dissonance, precipitated within each of these constituents, fosters curiosity and therefore provides an ideal motivational component for exploration.

    To compute the self shielding coefficient, it is necessary to know the point-wise cross-sections. In the unresolved resonance region, we do not know the parameters of each level but only the average parameters. Therefore we simulate the point-wise cross-section by random sampling of the energy levels and resonance parameters with respect to the Wigner law and the X 2 distributions, and by computing the cross-section in the same way as in the resolved regions. The result of this statistical calculation obviously depends on the initial parameters but also on the method of sampling, on the formalism which is used to compute the cross-section or on the weighting neutron flux. In this paper, we will survey the main phenomena which can induce discrepancies in self shielding computations. Results are given for typical dilutions which occur in nuclear reactors. 8 refs

    Full Text Available Leg length discrepancy (LLD is a biomechanical impediment, which is a potential factor in affecting musculoskeletal disorders in the rest of life, such as scoliosis, osteoarthritis and muscle tightness, or even tenderness in lumbar and pelvic area. Athletes who have developed LLD have symptoms in gait, running, standing posture. Skeletal regions related to the disorder are the lumbar spine, ilium, hip joint, greater trochanter and knee, or even ankle and plantar region. Muscles involved in these areas are numeous. In osteopathic management, the manual practitioner can use a lot of basic techniques to handle these dysfunctions. To cope with musculoskeletal problems, osteopathic manipulation techniques would be an ideal modality to alleviate the LLD syndrome. An overview of the mentioned topics of concern will be discussed in the review.

    Using a diamond-anvil cell (DAC) phase transformation and room temperature Equation of State (EOS) for some actinides and lanthanides were studied to multimegabar (megabar = 100 GPa) pressures. Experimental data are compared with the theoretically predicted crystal structural changes and the pressure-volume relationships. There is a general agreement between theory and experiment for the structural changes in the lighter actinides, however in detail there are some discrepancies still. A generalized trend for the phase transformations in the lanthanides can be seen, which again has broad agreement with theory. We conclude that an accurate and robust theoretical base for predicting the phase transformations in the f-electron metals can be developed by incorporating the DAC data

    One of the most important concerns of the postindustrial societies lies on the specification and quantification of risk, the Risk Assesment. However, the efforts and resources devoted to such goal have not avoided a growing worry about both the environmental conditions and the situations that potentially threaten it, generating an intense social debate about risks. In this framework, discrepancies between experts and public evaluations risks leaded to the study of social Risk perception. Several theoretical scopes have tried to characterize the phenomenon. A worthy conclusion of the empirical studies carried out on this issue is that all of them, experts and public, are influence by some factors which, in turns, affect their risk perception,. Specially striking is the fact that perception of risk among experts is also modulated by qualitative, personal and social factors. Social Risk Perception, through the process of Communication and Social Participation, has been configurated as a critical tool for both risk prevention and management

    Full Text Available A 14-year-old boy reported with a complaint of severe irregularity of lower teeth and forwardly placed upper teeth. History revealed snoring as an occasional complaint. The case was diagnosed as mild class II skeletally with increased lower anterior face height, bimaxillary transverse discrepancy leading to severe crowding in the lower arch, V-shaped upper arch with increased overjet and deep bite. Three phase treatment was planned. In the first phase, bimaxillary expansion with mid-symphyseal distraction osteogenesis and rapid maxillary expansion was carried out. After this phase of treatment, the episodes of snoring vanished. The second phase was 1 year of orthodontics to produce symmetric well-aligned arches in good function and aesthetics. Third, the treatment concluded with reduction-advancement genioplasty for correction of vertical excess and surgical camouflage.

    It was found by Hung, Myers and Smolkin that there is entropy discrepancy for the CFTs in 6-dimensional space–time, between the field theoretical and the holographic analyses. Recently, two different resolutions to this puzzle have been proposed. One of them suggests to utilize the anomaly-like entropy and the generalized Wald entropy to resolve the HMS puzzle, while the other one initiates the use of the entanglement entropy which arises from total derivative terms in the Weyl anomaly to explain the HMS mismatch. We investigate these two proposals carefully in this note. By studying the CFTs dual to Einstein gravity, we find that the second proposal cannot solve the HMS puzzle. Moreover, the Wald entropy formula is not well-defined on horizon with extrinsic curvatures, in the sense that, in general, it gives different results for equivalent actions.

    1999-06-01

    The orthodontic therapeutic sequence used in cases with dento-dental discrepancy for reduced mesiodistal size and congenital absent lateral upper incisors, is described. The importance of correct conoid tooth replacement in the programmed space between the other teeth and its restorative treatment in order to obtain the best biomechanical control is stressed. The contemporaneous presence of the form and volume anomaly of the 12th and the missing 22nd due to agenesia demanded an interdisciplinary approach. For the restoration of the conoid tooth the authors used a microhybrid composite for the alloy properties with the grain size of the inorganic particles. In fact this type of composite responds well to mechanical stress and has a high shining capacity and good aesthetical rendering. Meanwhile the temporary dental prothesis solution of the 22nd in this case has suggested the application of the artificial element on the superior Hawley holding plaque.

    2015-09-01

    The purpose of the present study was to analyse professional fingerprint examiners' investigative practices in the context of discrepancy decisions concerning challenging latents during fingerprint analysis and identification. The participants were fingerprint experts from the Forensic Laboratory of the Finnish National Bureau of Investigation. The data were from five audio-recorded "discrepancy meetings" where two examiners were discussing the rationale and justification for their differing interpretations of challenging and distorted fingerprint evidence. The meetings were chaired by the quality manager of the fingerprint group, who also in the first author of this article. The research questions addressed were as follows: What does the examiner see in the latent fingerprints? What does the examiner actively do with the latents? How were decisions made during the investigative process? In accordance with Goodwin's professional vision framework, the results revealed how the participants used partial and limited information in making judgments about the difficult and distorted latents. The examiners appeared to be involved in active, constructive efforts, mentally, to repair poor latents by supplementing with missing information. They also highlighted various aspects of latents by colour coding as well as manipulated fingerprint images in several ways so as to make the significant patterns easier to recognize. Because the methods and practices of characterizing latents were only vaguely specified, the examiners used locally developed ad hoc practices to facilitate their investigations, ending up with different interpretations. It is concluded in the article that the fingerprint community in Finland should make strong efforts to develop the methods of fingerprint investigation and determine clearer criteria for decision making and documentation practices. Furthermore, the interpretations made by fingerprint experts should be made more transparent to the customers

    Planktic foraminifera faunal assemblages have been used in the reconstruction of past oceanic states (e.g. the Last Glacial Maximum, the mid-Piacenzian Warm Period). However these reconstruction efforts have typically relied on inverse modeling using transfer functions or the modern analog technique, which by design seek to translate foraminifera into one or two target oceanic variables, primarily sea surface temperature (SST). These reconstructed SST data have then been used to test the performance of climate models, and discrepancies have been attributed to shortcomings in climate model processes and/or boundary conditions. More recently forward proxy models or proxy system models have been used to leverage the multivariate nature of proxy relationships to their environment, and to "bring models into proxy space". Here we construct ecological models of key planktic foraminifera taxa, calibrated and validated with World Ocean Atlas (WO13) oceanographic data. Multiple modeling methods (e.g. multilayer perceptron neural networks, Mahalanobis distance, logistic regression, and maximum entropy) are investigated to ensure robust results. The resulting models are then driven by a Late Pliocene climate model simulation with biogeochemical as well as temperature variables. Similarities and differences with previous model-proxy comparisons (e.g. PlioMIP) are discussed.

This study describes differences between older adults with insomnia and controls in sleep discrepancy, and tests the hypothesis that reduced sleep discrepancy following cognitive behavioural therapy for insomnia correlates with the magnitude of symptom improvement reported by older adults with insomnia. Participants were 63 adults >60 years of age with insomnia, and 51 controls. At baseline, participants completed sleep diaries for 7 days while wearing wrist actigraphs. After receiving cognitive behavioural therapy for insomnia, insomnia patients repeated this sleep assessment. Sleep discrepancy variables were calculated by subtracting actigraphic sleep onset latency and wake after sleep onset from respective self-reported estimates, pre- and post-treatment. Mean level and night-to-night variability in sleep discrepancy were investigated. Baseline sleep discrepancies were compared between groups. Pre-post-treatment changes in Insomnia Severity Index score and sleep discrepancy variables were investigated within older adults with insomnia. Sleep discrepancy was significantly greater and more variable across nights in older adults with insomnia than controls, P ≤ 0.001 for all. Treatment with cognitive behavioural therapy for insomnia was associated with significant reduction in the Insomnia Severity Index score that correlated with changes in mean level and night-to-night variability in wake after sleep onset discrepancy, P treatments for late-life insomnia. © 2014 European Sleep Research Society.

    Brain opioid peptide systems are known to play an important role in motivation, emotion, attachment behaviour, the response to stress and pain, and the control of food intake. Opioid peptides within the ventral striatum are thought to play a key role in the latter function, regulating the affective response to highly palatable, energy-dense foods such as those containing fat and sugar. It has been shown previously that stimulation of mu opiate receptors within the ventral striatum increases intake of palatable food. In the present study, we examined enkephalin peptide gene expression within the striatum in rats that had been given restricted daily access to an energy-dense, palatable liquid food, chocolate Ensure(R). Rats maintained on an ad libitum diet of rat chow and water were given 3-h access to Ensure(R) daily for two weeks. One day following the end of this period, preproenkephalin gene expression was measured with quantitative in situ hybridization. Compared with control animals, rats that had been exposed to Ensure(R) had significantly reduced enkephalin gene expression in several striatal regions including the ventral striatum (nucleus accumbens), a finding that was confirmed in a different group with Northern blot analysis. Rats fed this regimen of Ensure(R) did not differ in weight from controls. In contrast to chronic Ensure(R), acute ingestion of Ensure(R) did not appear to affect enkephalin peptide gene expression. These results suggest that repeated consumption of a highly rewarding, energy-dense food induces neuroadaptations in cognitive-motivational circuits.

    We explored self-discrepancy in men with body dysmorphic disorder (BDD) concerned about penis size, men without BDD but anxious about penis size, and controls. Men with BDD (n=26) were compared to those with small penis anxiety (SPA; n=31) and controls (n=33), objectively (by measuring) and investigating self-discrepancy: actual size, ideal size, and size they felt they should be according to self and other. Most men under-estimated their penis size, with the BDD group showing the greatest discrepancy between perceived and ideal size. The SPA group showed a larger discrepancy than controls. This was replicated for the perceptions of others, suggesting the BDD group internalised the belief that they should have a larger penis size. There was a significant correlation between symptoms of BDD and this discrepancy. This self-actual and self-ideal/self-should discrepancy and the role of comparing could be targeted in therapy.

    Online social media such as Twitter are widely used for mining public opinions and sentiments on various issues and topics. The sheer volume of the data generated and the eager adoption by the online-savvy public are helping to raise the profile of online media as a convenient source of news and public opinions on social and political issues as well. Due to the uncontrollable biases in the population who heavily use the media, however, it is often difficult to measure how accurately the online sphere reflects the offline world at large, undermining the usefulness of online media. One way of identifying and overcoming the online-offline discrepancies is to apply a common analytical and modeling framework to comparable data sets from online and offline sources and cross-analyzing the patterns found therein. In this paper we study the political spectra constructed from Twitter and from legislators' voting records as an example to demonstrate the potential limits of online media as the source for accurate public opinion mining, and how to overcome the limits by using offline data simultaneously.

    Full Text Available Everyone has experienced the potential discrepancy between what one judges as morally acceptable and what one actually does when a choice between alternative behaviors is to be made. The present study explores empirically whether judgment and choice of action differ when people make decisions on dilemmas involving moral issues. 240 participants evaluated 24 moral and non-moral dilemmas either by judging (Is it acceptable to… or reporting the choice of action they would make (Would you do…. We also investigated the influence of varying the number of people benefiting from the decision and the closeness of relationship of the decision maker with the potential victim on these two types of decision. Variations in the number of beneficiaries from the decision did not influence judgment nor choice of action. By contrast, closeness of relationship with the victim had a greater influence on the choice of action than on judgment. This differentiation between evaluative judgments and choices of action argues in favor of each of them being supported by (at least partially different psychological processes.

    2018-03-22

    Due to the difficulty of collecting labeled images for hundreds of thousands of visual categories, zero-shot learning, where unseen categories do not have any labeled images in training stage, has attracted more attention. In the past, many studies focused on transferring knowledge from seen to unseen categories by projecting all category labels into a semantic space. However, the label embeddings could not adequately express the semantics of categories. Furthermore, the common semantics of seen and unseen instances cannot be captured accurately because the distribution of these instances may be quite different. For these issues, we propose a novel deep semisupervised method by jointly considering the heterogeneity gap between different modalities and the correlation among unimodal instances. This method replaces the original labels with the corresponding textual descriptions to better capture the category semantics. This method also overcomes the problem of distribution difference by minimizing the maximum mean discrepancy between seen and unseen instance distributions. Extensive experimental results on two benchmark data sets, CU200-Birds and Oxford Flowers-102, indicate that our method achieves significant improvements over previous methods.

    Discrepancies (i.e., a subjective sense of falling short of one's own standards) are a key part of the perfectionism construct. Theory suggests discrepancies confer vulnerability to depressive symptoms. Since most research in this area is cross-sectional, longitudinal research is needed to disentangle directionality of relationships and to permit stronger causal inferences. Determining whether discrepancies are an antecedent of depressive symptoms, a consequence of depressive symptoms, or both is critical to understanding the discrepancies-depressive symptoms relationship. Knowledge about the temporal stability of discrepancies is also only starting to emerge, and it is unclear whether discrepancies predict incremental variance in depressive symptoms above and beyond neuroticism (i.e., a dispositional tendency to experience negative emotional states). The present study tested relationships among discrepancies, neuroticism, and depressive symptoms in 127 1st-year undergraduates using a 3-wave longitudinal design. Results suggest discrepancies may be understood as a trait-state where people are both highly consistent in their rank order on discrepancies and fluctuate somewhat in the level of discrepancies they experience at a particular point in time. As hypothesized, discrepancies predicted increases in depressive symptoms, even after controlling for neuroticism. Contrary to hypotheses, depressive symptoms did not predict changes in discrepancies. This study extends a long tradition of theory noting the depressing consequences of believing that one has fallen short of one's own standards. Harsh self-criticism and unobtainable self-expectations involving a strong sense of imperfection may be part of the premorbid personality of people vulnerable to depressive symptoms.

    Medication discrepancies occur in 70% of hospital patients, especially during discharge. In community settings, bag medication reconciliation events have demonstrated effectiveness in evaluating current medication use and identifying medication discrepancies. A bag medication reconciliation process was implemented in the hospital setting to decrease medication discrepancies by encouraging evaluation of medication adherence, side effects, and monitoring at posthospitalization follow-up. After implementation, a 7% decrease in reportable errors was noted.

    Borderline personality disorder (BPD) involves disordered self-conceptions, along with dysphoria and anxiety. The present study examined the role of actual-ideal (AI) and actual-ought (AO) self-discrepancies, and self-complexity as predictors of borderline personality features in a student population. AI and AO self-discrepancy magnitudes across all self-domains were assessed, along with self-complexity, idiographically and nomothetically. Borderline personality features were assessed using subscales of the Minnesota Multiphasic Personality Inventory (MMPI-2). Both AI and AO self-discrepancies were directly related to BPD personality features, in that those with larger self-discrepancies of both types reported more features. Self-complexity had no direct relationship to BPD personality features; rather, it moderated the relationship between AI, but not AO, self-discrepancies and BPD personality features. For individuals low in self-complexity, a stronger relationship between AI self-discrepancies and BPD personality features existed. This study is novel in its consideration of the impact of features of the self-system on BPD personality features. It highlights the important role that AO self-discrepancies, and the combined role of AI self-discrepancies and self-complexity, have in increasing vulnerability to BPD. The findings suggest that different pathways might be involved in the vulnerability to BPD, depending on self-discrepancy type and level of self-complexity.

    2012-01-01

    For many decades, models that can explain the behaviour of measurement condenser microphones have been proposed in the literature. These devices have an apparently simple working principle, a charged capacitor whose charge varies when one of its electrodes, the diaphragm, moves as a result of sound...... waves. However, measurement microphones must be manufactured very carefully due to their sensitivity to small changes of their physical parameters. There are different elements in a microphone, the diaphragm, the gap behind it, a back cavity, a vent for pressure equalization and an external medium. All...... visco-thermal losses is used to model measurement condenser microphones. The models presented are fully coupled and include a FEM model of the diaphragm. The behaviour of the acoustic variables in the gap and the effect of the pressure equalization vent are discussed, as well as the practical difficulty...

    The ATLAS Collaboration is engaged in precision measurement of fundamental Standard Model parameters, such as the W boson mass, the weak-mixing angle or the strong coupling constant. In addition, the production cross-sections of a large variety of final states involving high energetic jets, photons as well as single and multi vector bosons are measured multi differentially at several center of mass energies. This allows to test perturbative QCD calculations to highest precision. In addition, these measurements allow also to test models beyond the SM, e.g. those leading to anomalous gauge couplings. In this talk, we give a broad overview of the Standard Model measurement campaign of the ATLAS collaboration, where selected topics will be discussed in more detail.

    Boosted topologies allow to explore Standard Model processes in kinematical regimes never tested before. In such LHC challenging environments, standard reconstruction techniques quickly hit the wall. Targeting hadronic final states means to properly reconstruct energy and multiplicity of the jets in the event. In order to be able to identify the decay product of boosted objects, i.e. W bosons, $t\\bar{t}$ pairs or Higgs produced in association with $t\\bar{t}$ pairs, ATLAS experiment is currently exploiting several algorithms using jet grooming and jet substructure. This contribution will mainly cover the following ATLAS measurements: $t\\bar{t}$ differential cross section production and jet mass using the soft drop procedure. Standard Model measurements offer the perfect field to test the performances of new jet tagging techniques which will become even more important in the search for new physics in highly boosted topologies.”

    Congo red-stained sections of amyloid may show various colours between crossed polariser and analyser. The aims were to see how papers described the colours, to compare descriptions with illustrations, and to explain the colours. In 160 papers on Congo red-stained amyloid, the commonest descriptions were 'green birefringence' and 'apple-green birefringence'. In 191 figures in 82 papers, 59 (31%) showed a pure green colour, 62 (32%) showed green and yellow or blue and yellow, 38 (20%) showed green and a colour other than yellow, mostly red, and 32 (17%) showed other colours. Discrepancies between colours reported and illustrated were noted in 127 figures (66%). Most (77) were between green alone in descriptions and green and another colour in figures, and 30 were between green in descriptions and no green at all in figures. Pure green can be seen in ideal conditions, but more often there are green and yellow, explained by strain birefringence, and green and red or other combinations, explained by uncrossing of polariser and analyser. These other anomalous colours are just as characteristic of amyloid as the pure green colour. Many papers on Congo red-stained amyloid appear to describe what is expected theoretically rather than what is actually seen.

    Full Text Available Objectives: Medication errors are considered among the most common causes of morbidity and mortality in hospital setting. Among these errors are discrepancies identified during transfer of patients from one care unit to another, from one physician care to another, or upon patient discharge. Thus, the aims of this study were to identify the prevalence and types of medication discrepancies at the time of hospital admission to a tertiary care teaching hospital in Jordan and to identify risk factors affecting the occurrence of these discrepancies. Methods: A three months prospective observational study was conducted at the department of internal medicine at Jordan university hospital. During the study period, 200 patients were selected using convenience sampling, and a pre-prepared data collection form was used for data collection. Later, a comparison between the pre-admission and admission medication was conducted to identify any possible discrepancies, and all of these discrepancies were discussed with the responsible resident to classify them into intentional (documentation errors or unintentional. Linear regression analysis was performed to assess risk factors associated with the occurrence of unintentional discrepancies. Results: A total of 412 medication discrepancies were identified at the time of hospital admission. Among them, 144 (35% were identified as unintentional while the remaining 268 (65% were identified as intentional discrepancies. Ninety-four patients (47% were found to have at least one unintentional discrepancy and 92 patients (46% had at least one documentation error. Among the unintentional discrepancies, 97 (67% were found to be associated with a potential harm/deterioration to the patients. Increasing patients’ age (beta = 0.195, p-value = .013 and being treated by female residents (beta = 0.139, p-value = .045 were significantly associated with higher number of discrepancies. Conclusion: The prevalence of

    To compare the frequency of discrepancies in retracted reports of clinical trials with those in adjacent unretracted reports in the same journal. Blinded case-control study. Journals in PubMed. 50 manuscripts, classified on PubMed as retracted clinical trials, paired with 50 adjacent unretracted manuscripts from the same journals. Reports were randomly selected from PubMed in December 2012, with no restriction on publication date. Controls were the preceding unretracted clinical trial published in the same journal. All traces of retraction were removed. Three scientists, blinded to the retraction status of individual reports, reviewed all 100 trial reports for discrepancies. Discrepancies were pooled and cross checked before being counted into prespecified categories. Only then was the retraction status unblinded for analysis. Total number of discrepancies (defined as mathematically or logically contradictory statements) in each clinical trial report. Of 479 discrepancies found in the 100 trial reports, 348 were in the 50 retracted reports and 131 in the 50 unretracted reports. On average, individual retracted reports had a greater number of discrepancies than unretracted reports (median 4 (interquartile range 2-8.75) v 0 (0-5); Pretracted than those without a discrepancy (odds ratio 5.7 (95% confidence interval 2.2 to 14.5); Pretracted than unretracted reports: factual discrepancies (P=0.002), arithmetical errors (P=0.01), and missed P values (P=0.02). Results from a retrospective analysis indicated that citations and journal impact factor were unlikely to affect the result. Discrepancies in published trial reports should no longer be assumed to be unimportant. Scientists, blinded to retraction status and with no specialist skill in the field, identify significantly more discrepancies in retracted than unretracted reports of clinical trials. Discrepancies could be an early and accessible signal of unreliability in clinical trial reports. © Cole et al 2015.

    To assess the discrepancy rate for the interpretation of abdominal and pelvic computed tomography (CT) examinations among experienced radiologists. Ninety abdominal and pelvic CT examinations reported by three experienced radiologists who specialize in abdominal imaging were randomly selected from the radiological database. The same radiologists, blinded to previous interpretation, were asked to re-interpret 60 examinations: 30 of their previous interpretations and 30 interpreted by others. All reports were assessed for the degree of discrepancy between initial and repeat interpretations according to a three-level scoring system: no discrepancy, minor, or major discrepancy. Inter- and intrareader discrepancy rates and causes were evaluated. CT examinations included in the investigation were performed on 90 patients (43 men, mean age 59 years, SD 14, range 19-88) for the following indications: follow-up/evaluation of malignancy (69/90, 77%), pancreatitis (5/90, 6%), urinary tract stone (4/90, 4%) or other (12/90, 13%). Interobserver and intraobserver major discrepancy rates were 26 and 32%, respectively. Major discrepancies were due to missed findings, different opinions regarding interval change of clinically significant findings, and the presence of recommendation. Major discrepancy of between 26 and 32% was observed in the interpretation of abdominal and pelvic CT examinations. (orig.)

    2018-02-01

    Parents and adolescents often have discrepant views of parenting which pose challenges for researchers regarding how to deal with information from multiple informants. Although recent studies indicate that parent-adolescent discrepancies in reports of parenting can be useful in predicting adolescent outcomes, their findings are mixed regarding whether discrepancies relate to more positive or more negative adolescent outcomes. This study examined the longitudinal implications of parent-adolescent discrepancies in reports of parenting (warmth, monitoring, and reasoning) on adolescent behavioral, psychological, academic, and physical health outcomes among Mexican immigrant families in the United States. Participants were 604 adolescents (54% female, M age.wave1  = 12.41 years) and their parents. Taking a person-centered approach, this study identified distinct patterns of parent-adolescent discrepancies in parenting and their different associations with later adolescent outcomes. Adolescents' more negative perceptions of parenting relative to parents were associated with more negative adolescent outcomes, whereas adolescents' more positive perceptions relative to parents related to more positive adolescent outcomes. There were also variations in discrepancy patterns and their associations with adolescent outcomes between mother-adolescent vs. father-adolescent dyads. Findings of the current study highlight individual variations of discrepancies among parent-adolescent dyads and the importance of considering both the magnitude and direction of discrepancies regarding their associations with adolescent well-being.

    This study investigated risk factors for discrepant reporting of physical and sexual abuse among 172 homeless young adults. Discrepant reporting includes situations in which a respondent denies experiencing abuse in general but reports being a victim of specific forms of maltreatment. The results revealed that discrepant reporting rates tended to be highest for minor physical assault and for noncontact sexual abuse. Multivariate results revealed that demographic characteristics were important correlates of both discrepant physical and sexual abuse reporters. Family background characteristics also played a role in discrepant reporting for physical abuse. Overall, some young people with abuse histories are not adequately labeling their maltreatment experiences and, as a result, may not be receiving the necessary treatment.

    2005-01-01

    Results from a study to identify and characterize discrepancies between validation tests and high-fidelity analyses of compression-loaded panels are presented. First, potential sources of the discrepancies in both the experimental method and corresponding high-fidelity analysis models were identified. Then, a series of laboratory tests and numerical simulations were conducted to quantify the discrepancies and develop test and analysis methods to account for the discrepancies. The results indicate that the discrepancies between the validation tests and high-fidelity analyses can be attributed to imperfections in the test fixture and specimen geometry; test-fixture-induced changes in specimen geometry; and test-fixture-induced friction on the loaded edges of the test specimen. The results also show that accurate predictions of the panel response can be obtained when these specimen imperfections and edge conditions are accounted for in the analysis. The errors in the tests and analyses, and the methods used to characterize these errors are presented.

  7. Discrepancy-based and anticipated emotions in behavioral self-regulation.

    2011-10-01

    Discrepancies between one's current and desired states evoke negative emotions, which presumably guide self-regulation. In the current work we evaluated the function of discrepancy-based emotions in behavioral self-regulation. Contrary to classic theories of self-regulation, discrepancy-based emotions did not predict the degree to which people engaged in self-regulatory behavior. Instead, expectations about how future self-discrepancies would make one feel (i.e., anticipated emotions) predicted self-regulation. However, anticipated emotions were influenced by previous discrepancy-based emotional experiences, suggesting that the latter do not directly motivate self-regulation but rather guide expectations. These findings are consistent with the perspective that emotions do not necessarily direct immediate behavior, but rather have an indirect effect by guiding expectations, which in turn predict goal-directed action.

    It has been argued that memories that are inconsistent with one's self would differ from those that are consistent with the self. The present study addresses retrieval, phenomenology, rehearsal and narrative characteristics of autobiographical memories that are consistent versus discrepant with one's self. One hundred participants were asked to recall one self-consistent and one self-discrepant memory as well as an episode of telling these memories to others. They also filled out the Autobiographical Memory Questionnaire and the Centrality of Event Scale for each memory. Results showed no difference between self-consistent and self-discrepant memories in retrieval time, specificity or phenomenology. However, self-discrepant memory narratives contained more meaning-making statements and less autonomy than self-consistent memories. Compared to self-consistent memories, self-discrepant memories were told to fewer people, and listener responses were more negative when they were told. Results are discussed in relation to the functions these memories serve.

    Full Text Available This paper assessed factors that influence the internal controls in ensuring good corporate governance in financial institutions in developing economies with special reference to Zimbabwe. The research paper assessed how lack of internal controls affected good corporate governance and aimed to bring out elements of good corporate governance. It emerged that failure to effectively implement internal controls contributed significantly to poor corporate governance. The study discovered that internal control system overrides and the issue of “fact cat” directors also contributed to poor corporate governance. The study recommended that there is need for the board of directors to guarantee an organizational structure that clearly defines management responsibilities, authority and reporting relationships. There is also need to ensure that delegated responsibilities are effectively carried out to ensure compliance with internal controls of the financial institution concerned.

    2011-01-01

    The impacts of trade liberalization and open markets on global, regional, and local economies are a key consideration for those involved in government, business, and financial sectors. However, their impacts on health and social well-being of populations are not well-evidenced acknowledged within the health sector, let alone the impact on developing countries. As free trade becomes an inevitable outcome for many developing nations, the full implications of trade on economies, environments, and population health needs to be better articulated in order to ensure fully informed trade negotiations that support equitable outcomes. This article takes a broad look at the key issues for Papua New Guinea (PNG) in trade and how these translate to discrepancies in economic, health, and social benefits for its population. Despite its active trading and high GDP, only 10% of the population experience better economic and social outcomes. The bulk of PNG's population lives in poverty, challenged by geographical, cultural, and political barriers to better income, education, and health. Progress needs to be made to minimize these barriers and to allow more of PNG's population to experience the economic benefits generated through trade activities. A balance needs to be maintained between the desire of developed countries to broaden their markets, and the efforts of developing countries to promote and protect the health and well-being of their populations through increasing participation in global markets. PACER Plus presents an opportunity for pursuing alternative models of trade agreements that support and develop Pacific health.

    2011-04-01

    The topic of ensuring quality and compliance is and must be a top priority in the conduct of clinical trials, as warranted by regulatory guidelines as well as the inherent responsibility of the professionals conducting such research. Fast-growing emerging clinical geographies such as India demand special attention due to rapid growth and associated factors that may put study quality at risk. In this paper, we used the basic principle of PDCA (Plan, Do, Check, and Adjust) to structure the processes of a clinical trial from protocol to final analysis in order to highlight the interactive nature of involved people and processes required to ensure quality of data and site functioning.

    To determine the usefulness of autopsy findings in the quality improvement of patients care. The clinical and necropsy findings of all the cases, who died in hospital and had undergone autopsy examination at CMH, Kharian, from January 2001 to December 2003, were retrieved from record of clinical case sheet data and autopsy record of the hospital. The two were analyzed and compared according to the discrepancy classification. The exclusion and inclusion criteria, the international classification of disease (ICD) to code deaths, the global burden of disease (GBD) system to classify and group diseases, and the Goldman discrepancy classification to compare clinical and autopsy diagnosis and classify the discrepancies, were used as described. The death rate varied from 0.94% to 1.29% and autopsy rate from 4.69% to 10.10% annually between January 2001 and December 2003. The number of cases classified according to GBD system was 3 (5%) in Group 1, 26 (43.33 %) in Group 2 and 31 (51.66 %) in Group 3. The discrepancy classes included 9 (15 %) class I major discrepancies and 3 (5 %) class II major discrepancies. Non-discrepant diagnosis was seen in 37 cases (61.66 %) and 11 cases (18.32 %) were non classifiable. (author)

    2016-02-01

    Dual-process models of cognitive vulnerability to depression suggest that some individuals possess discrepant implicit and explicit self-views, such as high explicit and low implicit self-esteem (fragile self-esteem) or low explicit and high implicit self-esteem (damaged self-esteem). This study investigated whether individuals with discrepant self-esteem may employ depressive rumination in an effort to reduce discrepancy-related dissonance, and whether the relationship between self-esteem discrepancy and future depressive symptoms varies as a function of rumination tendencies. Hierarchical regressions examined whether self-esteem discrepancy was associated with rumination in an Australian undergraduate sample at Time 1 (N = 306; M(age) = 29.9), and whether rumination tendencies moderated the relationship between self-esteem discrepancy and depressive symptoms assessed 3 months later (n = 160). Damaged self-esteem was associated with rumination at Time 1. As hypothesized, rumination moderated the relationship between self-esteem discrepancy and depressive symptoms at Time 2, where fragile self-esteem and high rumination tendencies at Time 1 predicted the highest levels of subsequent dysphoria. Results are consistent with dual-process propositions that (a) explicit self-regulation strategies may be triggered when explicit and implicit self-beliefs are incongruent, and (b) rumination may increase the likelihood of depression by expending cognitive resources and/or amplifying negative implicit biases. © 2014 Wiley Periodicals, Inc.

    2017-06-01

    Despite low to moderate convergent correlations, assessment of youth typically relies on multiple informants for information across a range of psychosocial domains including parenting practices. Although parent-youth informant discrepancies have been found to predict adverse youth outcomes, few studies have examined contributing factors to the explanation of informant disagreements on parenting practices. The current study represents the first investigation to concurrently examine the role of mother and son's self-reported affective dimensions of temperament and depression as pathways to informant discrepancies on parenting practices. Within a community sample of 174 mother-son dyads, results suggest that whereas mother's self-reported temperament evidenced no direct effects on discrepancies, the association between the product term of mother's negative and positive temperament and discrepancies on positive parenting was fully mediated by mother's depression (a mediated moderation). In contrast, son's self-reported temperament evidenced both direct and indirect effects, partially mediated by depression, on rating discrepancies for positive parenting. All told, both son's self-reported affective dimensions of temperament and depression contributed to the explanation of discrepant reporting on parenting practices; only mother's self-reported depression, but not temperament, uniquely contributed. Results highlight the importance of considering both parent and youth's report in the investigation of informant discrepancies on parenting practices.

    2017-07-01

    The role of leadership in the management and delivery of health and allied health services is often discussed but lacks empirical research. Discrepancies are often found between leaders' self-ratings and followers' ratings of the leader. To our knowledge no research has examined leader-follower discrepancies and their association with organizational culture in mental health clinics. The current study examines congruence, discrepancy, and directionality of discrepancy in relation to organizational culture in 38 mental health teams (N = 276). Supervisors and providers completed surveys including ratings of the supervisor transformational leadership and organizational culture. Polynomial regression and response surface analysis models were computed examining the associations of leadership discrepancy and defensive organizational culture and its subscales. Discrepancies between supervisor and provider reports of transformational leadership were associated with a more negative organizational culture. Culture suffered more where supervisors rated themselves more positively than providers, in contrast to supervisors rating themselves lower than the provider ratings of the supervisor. Leadership and leader discrepancy should be a consideration in improving organizational culture and for strategic initiatives such as quality of care and the implementation and sustainment of evidence-based practice.

    Full Text Available Background. The ability of safety technologies to decrease errors, harm, and risk to patients has yet to be demonstrated consistently. Objective. To compare discrepancies between medication and intravenous fluid (IVF orders and bedside infusion pump settings within a pediatric intensive care unit (PICU before and after implementation of an interface between computerized physician order entry (CPOE and pharmacy systems. Methods. Within a 72-bed PICU, medication and IVF orders in the CPOE system and bedside infusion pump settings were collected. Rates of discrepancy were calculated and categorized by type. Results were compared to a study conducted prior to interface implementation. Expansion of PICU also occurred between study periods. Results. Of 455 observations, discrepancy rate decreased for IVF (p=0.01 compared to previous study. Overall discrepancy rate for medications was unchanged; however, medications infusing without an order decreased (p<0.01, and orders without corresponding infusion increased (p<0.05. Conclusions. Following implementation of an interface between CPOE and pharmacy systems, fewer discrepancies between IVF orders and infusion pump settings were observed. Discrepancies for medications did not change, and some types of discrepancies increased. In addition to interface implementation, changes in healthcare delivery and workflow related to ICU expansion contributed to observed changes.

    2012-11-01

    Four experiments examined the hypothesis that individuals who hold discrepant implicit and explicit self-esteem possess relatively strong self-image concerns. As a result, they may act irrationally when expressing sexual health attitudes. In support of the hypothesis, Experiments 1a and 1b demonstrate that large self-esteem discrepancy participants possess strong implicit self-image ambivalence relative to small self-esteem discrepancy participants. In Experiments 2 and 3, participants who varied in self-esteem discrepancies received either negative or positive (or no) feedback on an intelligence test, and then they were given an opportunity to express implicit and explicit attitudes toward condoms. Large self-esteem discrepancy participants who received a self-threat responded irrationally and expressed relatively strong negative implicit (but not explicit) attitudes toward condoms. However, this detrimental effect was completely reversed following a self-affirmation to large discrepancy participants. The implicit and explicit attitudes toward condoms of small discrepancy participants were unaffected by a self-threat or a self-affirmation.

    2013-04-01

    Experiences of closeness in romantic relationships are associated with heightened levels of relational well-being and mental health. However, individuals differ in the degree of closeness they desire in their relationships. This study used the construct of inclusion of other in self (IOS) to analyze discrepancies between individuals' actual and ideal levels of closeness in their relationships and the implications of these discrepancies for relational well-being and mental health. A longitudinal survey of partnered individuals demonstrated that optimal levels of relational well-being and mental health existed when individuals had minimal discrepancies between actual and ideal IOS, regardless of their actual levels of IOS. Individuals whose actual levels of IOS moved closer to their ideal levels over a 2-year period reported improved relational well-being and mental health. Individuals with little to no discrepancies between actual and ideal IOS were also less likely to break-up with their partners over time.

    Science.gov (United States)

    Alexander, M J; Higgins, E T

    1993-12-01

    Why do some people suffer from becoming a parent, whereas others do not? New parents' actual selves were related to their own hopes for themselves (ideal self) and to their spouse's sense of their responsibilities (ought self). Prebirth actual-ideal discrepancies predicted increased sadness or dejection after birth (especially for couples in longer marriages), whereas prebirth actual-ought discrepancies predicted decreased nervousness or agitation after birth (especially for mothers and couples with a less "easy" child). Becoming a parent introduces new demands that both interfere with attaining one's own hopes (increasing dejection in parents high in ideal [own] discrepancy) and shift attention to the new parenting role (decreasing agitation in parents high in ought [spouse] discrepancy).

    The discrepancy between abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major, unresolved problem with significant implications for the determination of chemical abundances throughout the Universe. In planetary nebulae (PNe), the most common explanation for the discrepancy is that two different gas phases coexist: a hot component with standard metallicity, and a much colder plasma enhanced in heavy elements. This dual nature is not predicted by mass loss theories, and direct observational support for it is still weak. In this work, we present our recent findings that demonstrate that the largest abundance discrepancies are associated with close binary central stars. OSIRIS-GTC tunable filter imaging of the faint O ii ORLs and MUSE-VLT deep 2D spectrophotometry confirm that O ii ORL emission is more centrally concentrated than that of [Oiii] CELs and, therefore, that the abundance discrepancy may be closely linked to binary evolution.

    In this era of ubiquitous information, patient record exchange among hospitals still has technological and individual barriers including resistance to information sharing. Most research on user attitudes has been limited to one type of user or aspect. Because few analyses of attitudes toward electronic patient records (EPRs) have been conducted, understanding the attitudes among different users in multiple aspects is crucial to user acceptance. This proof-of-concept study investigated the attitudes of users toward the inter-hospital EPR exchange system implemented nationwide and focused on discrepant behavioral intentions among three user groups. The system was designed by combining a Health Level 7-based protocol, object-relational mapping, and other medical informatics techniques to ensure interoperability in realizing patient-centered practices. After implementation, three user-specific questionnaires for physicians, medical record staff, and patients were administered, with a 70 % response rate. The instrument showed favorable convergent construct validity and internal consistency reliability. Two dependent variables were applied: the attitudes toward privacy and support. Independent variables comprised personal characteristics, work characteristics, human aspects, and technology aspects. Major statistical methods included exploratory factor analysis and general linear model. The results from 379 respondents indicated that the patients highly agreed with privacy protection by their consent and support for EPRs, whereas the physicians remained conservative toward both. Medical record staff was ranked in the middle among the three groups. The three user groups demonstrated discrepant intentions toward privacy protection and support. Experience of computer use, level of concerns, usefulness of functions, and specifically, reason to use electronic medical records and number of outpatient visits were significantly associated with the perceptions. Overall, four

    Medication discrepancies are medication-related problems (MRPs) that frequently occur when patients are transferred between settings of care. Older patients are at high risk for several reasons, including high consumption of medicines, and physical and cognitive deficiencies that can impair the communication process. Most previous studies that have evaluated medication discrepancies used instruments designed for clinical practice, but a well-validated and reliable instrument for clinical research is still lacking. The aims of this study were to (i) develop an instrument to characterize medication discrepancies that fulfils quality requirements for classification of MRPs related to continuity of care and (ii) assess its content validity and inter-rater reliability. The instrument was developed based on three main inputs: (i) a literature review to collect information about the quality requirements of instruments to characterize MRPs; (ii) another literature review to identify existing instruments to characterize MRPs and, more specifically, medication discrepancies; and (iii) previous experience from a pilot study on Belgian patients discharged from surgical and medical wards. Content validity was assessed using a modified Delphi technique with 11 healthcare professionals. Content validity indexes were calculated. For inter-rater reliability, three pharmacists (one experienced and two naive) were asked to identify and categorize (type and cause of) unintentional medication discrepancies for 21 patients discharged from hospital into the community. The intra-class correlation coefficient was calculated to compare the number of discrepancies identified, and a paradox-resistant index (AC1) was used to determine the inter-rater reliability for the type and cause of the discrepancy. The instrument had 54 items classified in three sections (type of discrepancy, cause and intervention), with detailed specifications on how to use it. All evaluations relative to content

    Full Text Available With the rapid growth of network technologies, users are used to accessing various services with their mobile devices. To ensure security and privacy in mobility networks, proper mechanisms to authenticate the mobile user are essential. In this paper, a mobility network authentication scheme based on elliptic curve cryptography is proposed. In the proposed scheme, a mobile user can be authenticated without revealing who he is for user anonymity, and a session key is also negotiated to protect the following communications. The proposed mobility network authentication scheme is analyzed to show that it can ensure security, user anonymity, and convenience. Moreover, Burrows-Abadi-Needham logic (BAN logic is used to deduce the completeness of the proposed authentication scheme.

    Tamura, Shinsuke; Yanase, Tatsuro; Nishi, Naoya

    This paper discusses a mechanism to ensure safe behaviors of HMSs (Holonic Manufacturing Systems). The change from low-variety high-volume to high-variety low-volume production requires highly flexible and adaptive manufacturing systems. Multi agent systems, in which decisions are made through cooperation among autonomous and cooperative elements, fulfill these requirements by exploiting full abilities of individual elements while eliminating various bottlenecks that exist in conventional systems. However, highly adaptive features induce non-deterministic behaviors of systems, and make it difficult to adopt multi agent systems as primary bases of manufacturing systems. In order to apply these systems to large and complicated applications, mechanisms that make their behaviors more predictable are essential. HMSs are a kind of multi agent systems, and an HMS safety ensuring mechanism proposed here is one of the attempts to make behaviors of multi agent systems more predictable.

    Progress in science is dependent on a strong foundation of reliable results. The publish or perish paradigm in research, coupled with an increase in retracted articles from the peer-reviewed literature, is beginning to erode the trust of both the scientific community and the public. The NIH is combating errors by requiring investigators to follow new guidelines addressing scientific premise, experimental design, biological variables, and authentication of reagents. Herein, we discuss how implementation of NIH guidelines will help investigators proactively address pitfalls of experimental design and methods. Careful consideration of the variables contributing to reproducibility helps ensure robust results. The NIH, investigators, and journals must collaborate to ensure that quality science is funded, explored, and published. Copyright © 2018 American Society for Investigative Pathology.

    Johnson, Kain; Sully, Andrew; Anthenat, Bruce

    2014-01-01

    The safety and effectiveness of customized formulations have always been priorities for compounding pharmacists, perhaps even more so since a tragic outbreak of meningitis in 2012 was traced to preparations from the New England Compounding Center in Framingham, Massachusetts. Since that time, pharmaceutical compounding in the U.S. has been the focus of renewed interest from the public and from government organizations and regulatory bodies created to ensure patient safety. As a result, responsible compounders have responded to ensure--to even greater levels--the purity and safety of the formulations they prepare. One tool useful in doing so is the mechanical vial washer, which can produce cleaner vials (and/or ampules, syringes, and cartridges, depending on the washer model) more consistently than does washing vessels by hand. In this article, several such washers appropriate for use in a compounding pharmacy are profiled, and a pharmacist's experience in using one of those models is described.

    2016-06-01

    The use of qualitative research methodology is well established for data generation within healthcare research generally and clinical pharmacy research specifically. In the past, qualitative research methodology has been criticized for lacking rigour, transparency, justification of data collection and analysis methods being used, and hence the integrity of findings. Demonstrating rigour in qualitative studies is essential so that the research findings have the "integrity" to make an impact on practice, policy or both. Unlike other healthcare disciplines, the issue of "quality" of qualitative research has not been discussed much in the clinical pharmacy discipline. The aim of this paper is to highlight the importance of rigour in qualitative research, present different philosophical standpoints on the issue of quality in qualitative research and to discuss briefly strategies to ensure rigour in qualitative research. Finally, a mini review of recent research is presented to illustrate the strategies reported by clinical pharmacy researchers to ensure rigour in their qualitative research studies.

    With putting in operation the first digital TELEPERM XS I and C systems for functions important to safety in nuclear power plants, ensuring long-term availability and reliable operation of TELEPERM XS systems gains increasing importance. On the one hand, the modular structure of TELEPERM XS has already been optimized during system development such that the application-specific functions are independent of the version of hardware components and system software. On the other hand, hardware-independent, tool-based engineering procedures ensure that the application software of installed I and C systems can be flexibly adapted to modified plant requirements while at the same time the very high software quality is retained. Quality-assured procedures and an actively organized configuration management guarantee that the functionality and the availability of the I and C systems keep their qualified standard. This paper discusses aspects of the configuration management for TELEPERM XS I and C systems. (author)

    Rote, Wendy M; Smetana, Judith G

    2016-10-01

    Parent-child discrepancies pervade the family literature; they appear in reports of relationship dynamics (e.g., conflict; Laursen et al. 1998), parent and child behaviors (e.g., monitoring; De Los Reyes et al. 2010), and individual family members' beliefs (e.g., parental legitimate authority; Smetana 2011). Discrepancies are developmentally normative (Steinberg 2001) but also may be indicators of relationship and adjustment problems for teens (Ohannessian 2012). Because of this variation, it is important to consider the extent to which parent-child discrepancies are a function of both the dyad and the family construct considered. The present study contributed to our understanding of informant discrepancies in family relationships by considering the patterning, consistency, and correlates of mother-adolescent discrepancies across three family constructs that vary in their objectivity. Using person-centered analyses, discrepancies in adolescents' and mothers' ratings of parents' right to know about teens' activities, mothers' knowledge of them, and positive mother-adolescents relationships were examined in 167 middle class, primarily European American mother-adolescent dyads (M teen age = 15.68 years, SD = .64, 53 % female). Each construct was best described by three profiles, one where adolescents' standardized ratings were consistently higher than mothers', one showing the reverse, and one revealing little disagreement. Adolescent-reported problem behavior (but not depression), behavioral and psychological control, and mothers' wellbeing significantly predicted profile membership. Most dyads maintained consistent membership in a discrepancy profile across at least two family constructs. Results contribute to understanding the different sources of discrepancies in views of the family.

    Many young adolescents are dissatisfied with their body due to a discrepancy between their ideal and actual body size, which can lead to weight cycling, eating disorders, depression, and obesity. The current study examined the associations of parental and peer factors with fifth-graders’ body image discrepancy, physical self-worth as a mediator between parental and peer factors and body image discrepancy, and how these associations vary by child’s sex. Body image discrepancy was defined as the difference between young adolescents’ self-perceived body size and the size they believe a person their age should be. Data for this study came from Healthy Passages, which surveyed 5,147 fifth graders (51 % females; 34 % African American, 35 % Latino, 24 % White, and 6 % other) and their primary caregivers from the United States. Path analyses were conducted separately for boys and girls. The findings for boys suggest father nurturance and getting along with peers are related negatively to body image discrepancy; however, for girls, fear of negative evaluation by peers is related positively to body image discrepancy. For both boys and girls, getting along with peers and fear of negative evaluation by peers are related directly to physical self-worth. In addition, mother nurturance is related positively to physical self-worth for girls, and father nurturance is related positively to physical self-worth for boys. In turn, physical self-worth, for both boys and girls, is related negatively to body image discrepancy. The findings highlight the potential of parental and peer factors to reduce fifth graders’ body image discrepancy. PMID:23334988

  16. KEY ASPECTS OF ENSURING ENERGY EFFICIENCY OF BUILDINGS AND STRUCTURES

    2017-06-01

    Full Text Available The paper is based on the review of the foreign and national academic literature and intended to emphasize the issues of ensuring energy efficiency of buildings and structures applicable to all the countries as for reconstruction of existing buildings as for erection of new ones . The author highlights the key aspects of the provision of energy efficiency of buildings and structures in some foreign countries. The conclusion is made that the studies are mainly aimed at discovering new heat insulation materials, whereby polystyrene insulation is found to be the most widespread wall insulation material in a number of countries. At the same time, it is observed that the ongoing research is focused on solutions to optimize the structure of walling systems in terms of both insulant thickness and the number and sequence of insulation layers in the walling structure. A conclusion is made that hyper insulation of external walls leads to considerable expenses arising due to cooling during the summer season. The use of prefabricated vacuum panels as a heat insulation layer and off-the-shelf single-layer structures, subject to their heat insulation characteristics, appears a more constructive way to meet the energy efficiency requirements, as the arrangement of ideal air space in multilayered walls proves a significant challenge today. One of the most promising ways to ensure energy efficiency is the use of multifunctional polyvalent walls and provision of polyvalent heat supply from renewable energy sources. Since energy efficiency depends on the spatial arrangement of buildings, construction must ensure a minimum ratio of the area of enclosing structures to the overall building volume (by adding on new facilities in case of reconstruction. It is noted that a systemic approach to ensuring energy efficiency of buildings is impossible without proper regard to the environmental parameters of heat insulation materials.

  20. Cep63 and cep152 cooperate to ensure centriole duplication.

    Directory of Open Access Journals (Sweden)

    Nicola J Brown

    Full Text Available Centrosomes consist of two centrioles embedded in pericentriolar material and function as the main microtubule organising centres in dividing animal cells. They ensure proper formation and orientation of the mitotic spindle and are therefore essential for the maintenance of genome stability. Centrosome function is crucial during embryonic development, highlighted by the discovery of mutations in genes encoding centrosome or spindle pole proteins that cause autosomal recessive primary microcephaly, including Cep63 and Cep152. In this study we show that Cep63 functions to ensure that centriole duplication occurs reliably in dividing mammalian cells. We show that the interaction between Cep63 and Cep152 can occur independently of centrosome localisation and that the two proteins are dependent on one another for centrosomal localisation. Further, both mouse and human Cep63 and Cep152 cooperate to ensure efficient centriole duplication by promoting the accumulation of essential centriole duplication factors upstream of SAS-6 recruitment and procentriole formation. These observations describe the requirement for Cep63 in maintaining centriole number in dividing mammalian cells and further establish the order of events in centriole formation.

    Full Text Available The article considers evolution of development of the paradigm of ensuring competitive advantages of an enterprise. Foreign and domestic scientists focus on individual directions of development of competitive advantages and pay insufficient attention to new management concepts – development of the information society, knowledge economy and dynamism of integration processes. The goal of the study is formation of the modern paradigm of ensuring competitive advantages of an enterprise with consideration of tendencies of development of the knowledge economy, information society and integration processes. Enterprise competitiveness is a synergetic characteristic, which reflects enterprise capability of dynamic response to changes of the market situation with the aim of keeping predominance over other economic subjects. Management of the future, on the basis of the management 2.0 concept, should take into account interests not only of top management and shareholders but also employees, local communities and territories and meet requirements of the society in general, individual groups of consumers and tendencies of development of managerial and information technologies. The paradigm of the modern theory of ensuring competitive advantages should include models of keeping competitive advantages in the existing markets and models of development of future markets; strategy of development of enterprise competitiveness, human capital development and efficient enterprise management.

  2. Physics-informed machine learning approach for reconstructing Reynolds stress modeling discrepancies based on DNS data

    2017-03-01

    Turbulence modeling is a critical component in numerical simulations of industrial flows based on Reynolds-averaged Navier-Stokes (RANS) equations. However, after decades of efforts in the turbulence modeling community, universally applicable RANS models with predictive capabilities are still lacking. Large discrepancies in the RANS-modeled Reynolds stresses are the main source that limits the predictive accuracy of RANS models. Identifying these discrepancies is of significance to possibly improve the RANS modeling. In this work, we propose a data-driven, physics-informed machine learning approach for reconstructing discrepancies in RANS modeled Reynolds stresses. The discrepancies are formulated as functions of the mean flow features. By using a modern machine learning technique based on random forests, the discrepancy functions are trained by existing direct numerical simulation (DNS) databases and then used to predict Reynolds stress discrepancies in different flows where data are not available. The proposed method is evaluated by two classes of flows: (1) fully developed turbulent flows in a square duct at various Reynolds numbers and (2) flows with massive separations. In separated flows, two training flow scenarios of increasing difficulties are considered: (1) the flow in the same periodic hills geometry yet at a lower Reynolds number and (2) the flow in a different hill geometry with a similar recirculation zone. Excellent predictive performances were observed in both scenarios, demonstrating the merits of the proposed method.

    We examined the relationships between parent-adolescent discrepancies in perceived parenting characteristics (indexed by parental responsiveness, parental demandingness, and parental control) and adolescent developmental outcomes (indexed by achievement motivation and psychological competence) in poor families in Hong Kong. A sample of 275 intact families having at least one child aged 11-16 experiencing economic disadvantage were invited to participate in the study. Fathers and mothers completed the Parenting Style Scale and Chinese Parental Control Scale, and adolescents completed the Social-Oriented Achievement Motivation Scale and Chinese Positive Youth Development Scale in addition to paternal and maternal Parenting Style Scale and Chinese Parental Control Scale. Results indicated that parents and adolescents had different perceptions of parental responsiveness, parental demandingness, and paternal control, with adolescents generally perceived lower levels of parenting behaviors than did their parents. While father-adolescent discrepancy in perceived paternal responsiveness and mother-adolescent discrepancy in perceived maternal control negatively predicted adolescent achievement motivation, mother-adolescent discrepancy in perceptions of maternal responsiveness negatively predicted psychological competence in adolescents experiencing economic disadvantage. The present findings provided support that parent-child discrepancies in perceived parenting characteristics have negative impacts on the developmental outcomes of adolescents experiencing economic disadvantage. The present study addresses parent-child discrepancies in perceived parental behaviors as "legitimate" constructs, and explores their links with adolescent psychosocial development, which sheds light for researchers and clinical practitioners in helping the Chinese families experiencing economic disadvantage.

    We investigate the discrepancy between the two-dimensional projected lensing mass and the dynamical mass for an ensemble of 97 strong gravitational lensing systems discovered by the Sloan Lens ACS Survey, the BOSS Emission-Line Lens Survey (BELLS), and the BELLS for GALaxy-Lyα EmitteR sYstems Survey. We fit the lensing data to obtain the Einstein mass and use the velocity dispersion of the lensing galaxies provided by the Sloan Digital Sky Survey to get the projected dynamical mass within the Einstein radius by assuming the power-law mass approximation. The discrepancy is found to be obvious and quantified by Bayesian analysis. For the singular isothermal sphere mass model, we obtain that the Einstein mass is 20.7% more than the dynamical mass, and the discrepancy increases with the redshift of the lensing galaxies. For the more general power-law mass model, the discrepancy still exists within a 1σ credible region. We suspect the main reason for this discrepancy is mass contamination, including all invisible masses along the line of sight. In addition, the measurement errors and the approximation of the mass models could also contribute to the discrepancy.

    Do men and women have different ideals for their friendships? What do men and women experience when their actual friendship experiences fall short of their ideals? The authors of the current study investigated gender differences in real-ideal same-sex best friendships and friendship discrepancy scores. Correlates of friendship discrepancies were also examined. For this purpose, a sample of 382 college students completed the McGill Friendship Questionnaire (M. J. Mendelson & F. E. Aboud, 1999), the Friendship Conflict Scale (M. Demir & L. A. Weitekamp, 2007), the Need Satisfaction Scale (J. G. La Guardia, R. M. Ryan, C. E. Couchman, & E. L. Deci, 2000), and the PANAS (D. Watson, L. A. Clark, & A. Tellegen, 1988). Results showed that (a) the real and ideal best friendships of women were higher in quality and lower in conflict when compared to those of men; and (b) men's discrepancy scores for friendship quality were significantly higher when compared to women, whereas no differences were obtained on friendship conflict discrepancy scores. Findings also revealed that for both women and men, discrepancy scores were negatively related to friendship satisfaction, happiness, and satisfaction of basic psychological needs. The authors discuss the findings in light of theory, highlight ways to address relationship discrepancies, and make suggestions for future research.

    This study examined whether body image self-discrepancy was a correlate of depressive symptoms among 556 early adolescents (45% girls; M age  = 11.65, SD = .94 years). Participants completed self-report measures of their self-perceived actual and ideal body shapes and depressive symptoms. Sex-stratified polynomial regressions were used to examine the associations between depressive symptoms and (1) agreement (i.e., similar actual and ideal body shapes); (2) discrepancy (i.e., different actual and ideal body shapes); (3) direction of discrepancy (i.e., actual > ideal or actual self-perceptions are). For both sexes, depressive symptoms were more frequent when the direction of the discrepancy was such that participants perceived their actual body was larger than their ideal body. Furthermore, depressive symptoms were more frequent when the degree of the discrepancy between actual and ideal body shape perceptions was larger. Based on these findings, body image self-discrepancy may be a risk factor for depressive symptoms among early adolescents. Copyright © 2016 Society for Adolescent Health and Medicine.

    Background No methodological standards are available for researchers and clinicians to examine medication discrepancies between health care settings. Systematic methods of examining medication discrepancies will allow researchers and clinicians to better understand factors driving medication discrepancies, to better measure effects of medication reconciliation interventions, and to compare findings across studies. Objective This article proposes a four-phase approach for systematically collecting medication data and measuring medication discrepancies between a hospital and community pharmacies. Methodologic considerations related to studying medication discrepancies in health services research are also discussed. Methods A multi-disciplinary study team developed a four-phase systematic approach to improve quality of data and study rigor: 1) operationalization of a medication discrepancy, 2) acquiring medication data, 3) abstraction of medication data and creation of dataset, and 4) measuring and reporting medication discrepancies. Results Using this phase-based approach, the study team successfully identified and reported medication discrepancies between a hospital and community pharmacies at the patient, medication, and community pharmacy units of analyses. Conclusions Systematically measuring medication discrepancies that occur in the care transitions process is a critical step as researchers, clinicians, and other stakeholders work to improve health care quality and patient outcomes. This article detailed how a phase-based approach can be used in research to examine medication discrepancies as well as address the complexity of collecting medication data and analyzing medication discrepancies. Such methods should be considered when developing, conducting, and reporting research on medication discrepancies. PMID:26781670

Canada, the USA, and UK have incorporated medication reconciliation as a priority area for national patient safety initiatives and goals. The UK national guidance excludes the pediatric population. The aim of this review was to explore the occurrence of medication discrepancies in the pediatric population. The primary objective was to identify studies reporting the rate and clinical significance of the discrepancies and the secondary objective was to ascertain whether any specific interventions have been used for medication reconciliation in pediatric settings. The following electronic bibliographic databases were used to identify studies: PubMed, OVID EMBASE (1980 to 2012 week 1), ISI Web of Science, ISI Biosis, Cumulative Index to Nursing and Allied Health Literature, and OVID International Pharmaceutical Abstracts (1970 to January 2012). Primary studies were identified that observed medication discrepancies in children under 18 years of age upon hospital admission, transfer and discharge, or had reported medication reconciliation interventions. Two independent reviewers screened titles and abstracts for relevant articles and extracted data using pre-defined data fields, including risk of bias assessment. Ten studies were identified with variances in reportage of stage and rate of discrepancies. Studies were heterogeneous in definitions, methods, and patient populations. Most studies related to admissions and reported consistently high rates of discrepancies ranging from 22 to 72.3 % of patients (sample size ranging from 23 to 272). Seven of the studies were low-quality observational studies and three studies were 'grey literature' non-peer reviewed conference abstracts. Studies involving small numbers of patients have shown that medication discrepancies occur at all transitions of care in children. Further research is required to investigate and demonstrate how

    We examine the relationships between work-to-family conflict, time allocation across work activities, and the outcomes of work satisfaction, well-being, and salary in the context of self-regulation and self-discrepancy theories. We posit work-to-family conflict is associated with self-discrepant time allocation such that employees with higher levels of work-to-family conflict are likely to allocate less time than preferred to work activities that require greater self-regulatory resources (e.g., tasks that are complex, or those with longer term goals that delay rewards and closure) and allocate more time than preferred to activities that demand fewer self-regulatory resources or are replenishing (e.g., those that provide closure or are prosocial). We suggest this self-discrepant time allocation (actual vs. preferred time allocation) is one mechanism by which work-to-family conflict leads to negative employee consequences (Allen, Herst, Bruck, & Sutton, 2000; Mesmer-Magnus & Viswesvaran, 2005). Using polynomial regression and response surface methodology, we find that discrepancies between actual and preferred time allocations to work activities negatively relate to work satisfaction, psychological well-being, and physical well-being. Self-discrepant time allocation mediates the relationship between work-to-family conflict and work satisfaction and well-being, while actual time allocation (rather than the discrepancy) mediates the relationship between work-to-family conflict and salary. We find that women are more likely than men to report self-discrepant time allocations as work-to-family conflict increases. (c) 2015 APA, all rights reserved.

    Full Text Available Objective: Evaluate side-to-side discrepancies in children with hemiplegic cerebral palsy (HCP, and investigate associations of these discrepancies with patients’ age at initiation of physical therapy, motor and cognitive function, and degree of activities and social participation. Method: We obtained eight side-to-side measurements from 24 HCP children with mean age 49.3±5.2 months. Results: Early initiation of physical therapy was associated with lower discrepancy in hand length (p=0.037. Lower foot length discrepancy was associated with lower requirement for caregiver assistance in activities related to mobility. Increased side-to-side discrepancy was associated with reduced wrist extension and increased spasticity. Discrepancy played a larger role in children with hemineglect and in those with right involvement. Conclusion: Increased discrepancy in HCP children was associated with reduced degree of activity/social participation. These results suggest an association between functional use of the extremities and limb growth.

    The work conditions often may compromise a company ability to supply their employees with adequate, hot meals. For heavy labor workers and some office employees it is important to restore energy and nutrients with food, balanced in nutrients. The lack of adequate nutritive support can give a negative impact on different organs functions. One of the main principles of healthy nutrition is - diet must be balanced in nutrients. Which is easy to say, but difficult to implement, especially on some industries. Complete and balanced liquid and ready-to-use nutrition is new trend in nutrition of healthy people who cannot consume optimal diet, and in people with the risk of nutrient deficiencies. One-two packs of Ensure daily can significantly improve a worker ration. 2 and more packs could serve as a real complete and balanced lunch (>or=780 kcal). Also Ensure is easy to store and to deliver in distant places of work and can be recommended for use as a convenient, complete and balanced nutrition on work.

    Objective To investigate the consistency of autobiographical memory of people seeking asylum, in light of the assumption that discrepancies in asylum seekers' accounts of persecution mean that they are fabricating their stories. Design Repeated interviews. Setting England, 1999 and 2000. Participants Community sample of 27 Kosovan and 12 Bosnian refugees. Main outcome measures Discrepancies in repeated descriptions of one traumatic and one non-traumatic event, including specific details, rated as central or peripheral to the event. Self report measures of post-traumatic stress disorder and depression. Results Discrepancies between an individual's accounts were common. For participants with high levels of post-traumatic stress, the number of discrepancies increased with length of time between interviews. More discrepancies occurred in details peripheral to the account than in details that were central to the account. Conclusion The assumption that inconsistency of recall means that accounts have poor credibility is questionable. Discrepancies are likely to occur in repeated interviews. For refugees showing symptoms of high levels of post-traumatic stress, the length of the application process may also affect the number of discrepancies. Recall of details rated by the interviewee as peripheral to the account is more likely to be inconsistent than recall of details that are central to the account. Thus, such inconsistencies should not be relied on as indicating a lack of credibility. What is already known on this topicDiscrepancies between accounts of an event are often used to judge the credibility of asylum seekersWhat this study addsDiscrepancies arise between two accounts of the same event even when there is no reason for fabricationRefugees with high levels of post-traumatic stress are more likely to give inconsistent accounts if they have a long time to wait between interviewsInterviewees are more likely to be inconsistent in details that they rate as peripheral

    To evaluate the discrepancies between clinical and autopsy diagnoses in patients who died in the pediatric intensive care units (PICUs) of a tertiary care university hospital. A prospective study of all consecutive autopsies discussed at monthly mortality conferences over 5 years. Discrepancies between premortem and autopsy diagnoses were classified according to modified Goldman et al criteria. From January 1, 2011, to December 31, 2015, a total of 2,679 children were admitted to the two PICUs of our hospital; 257 (9.6%) died, 150 (58.4%) underwent autopsy, and 123 were included. Complete concordance between clinical and postmortem diagnoses was observed in 86 (69.9%) patients; 20 (16.3%) had a class I discrepancy, and eight (6.5%) had a class II discrepancy. Comparing 2011 and 2015, the rate of major discrepancies decreased from 31.6% to 15%. Our results emphasize the importance of autopsy to clarify the cause of death and its potential contribution to improvement of team performance and quality of care. © American Society for Clinical Pathology, 2016.

    The thrombus length may be overestimated on early arterial computed tomography angiography (CTA) depending on the collateral status. We evaluated the value of a grading system based on the thrombus length discrepancy on dual-phase CT in outcome prediction. Forty-eight acute ischemic stroke patients with M1 occlusion were included. Dual-phase CT protocol encompassed non-contrast enhanced CT, CTA with a bolus tracking technique, and delayed contrast enhanced CT (CECT) performed 40s after contrast injection. The thrombus length discrepancy between CTA and CECT was graded by using a three-point scale: G0 = no difference; G1 = no difference in thrombus length, but in attenuation distal to thrombus; G2 = difference in thrombus length. Univariate and multivariate analyses were performed to define independent predictors of poor clinical outcome at 3 months. The thrombus discrepancy grade showed significant linear relationships with both the collateral status (P = 0.008) and the presence of antegrade flow on DSA (P = 0.010) with good interobserver agreement (κ = 0.868). In a multivariate model, the presence of thrombus length discrepancy (G2) was an independent predictor of poor clinical outcome [odds ratio = 11.474 (1.350-97.547); P =0.025]. The presence of thrombus length discrepancy on dual-phase CT may be a useful predictor of unfavourable clinical outcome in acute M1 occlusion patients. (orig.)

    Because loneliness is a subjective experience, it is often examined using self-reports. Yet, researchers have started to use other-reports to examine loneliness. As previous research suggests that discrepancies between self- and other views might have important implications for adolescents' mental health, the current study examines discrepancies in multi-informant reports on adolescents' loneliness in relation with prosocial behavior, aggression, and adolescents' parent-related loneliness. The sample consisted of 374 mother-adolescent dyads and 318 father-adolescent dyads (41.80% male, M age  = 15.67 years, SD = 1.25). Results indicated that informants used different reference points to assess adolescents' peer-related loneliness, but were otherwise comparable. Moreover, informant discrepancies were associated with greater adolescents' reported parent-related loneliness. The current study did not provide evidence that discrepancies were related to prosocial or aggressive behavior. The current study adds to the notion that other-reports on loneliness show substantial convergence with self-reports. In addition, this study indicates that the discrepancy between other- and self-reports on loneliness holds valuable information for adolescent socio-emotional adjustment.

    Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Boys who experience stress about being perceived as "sub-masculine" may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential "threats" to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

    A new, Mandel–Paule-type procedure for statistical processing of one-parameter discrepant experimental data is described. The procedure enables one to estimate a contribution of unrecognized experimental errors into the total experimental uncertainty as well as to include it in analysis. A definition of discrepant experimental data for an arbitrary number of measurements is introduced as an accompanying result. In the case of negligible unrecognized experimental errors, the procedure simply reduces to the calculation of the weighted average and its internal uncertainty. The procedure was applied to the statistical analysis of half-life experimental data; Mean half-lives for 20 actinides were calculated and results were compared to the ENSDF and DDEP evaluations. On the whole, the calculated half-lives are consistent with the ENSDF and DDEP evaluations. However, the uncertainties calculated in this work essentially exceed the ENSDF and DDEP evaluations for discrepant experimental data. This effect can be explained by adequately taking into account unrecognized experimental errors. - Highlights: ► A new statistical procedure for processing one-parametric discrepant experimental data has been presented. ► Procedure estimates a contribution of unrecognized errors in the total experimental uncertainty. ► Procedure was applied for processing half-life discrepant experimental data. ► Results of the calculations are compared to the ENSDF and DDEP evaluations.

    Disinhibited eating (i.e., the tendency to overeat, despite intentions not to do so, in the presence of palatable foods or other cues such as emotional stress) is strongly linked with obesity and appears to be associated with both implicit (automatic) and explicit (deliberative) food attitudes. Prior research suggests that a large discrepancy between implicit and explicit food attitudes may contribute to greater levels of disinhibited eating; however this theory has not been directly tested. The current study examined whether the discrepancy between implicit and explicit attitudes towards chocolate could predict both lab-based and self-reported disinhibited eating of chocolate. Results revealed that, whereas neither implicit nor explicit attitudes alone predicted disinhibited eating, absolute attitude discrepancy positively predicted chocolate consumption. Impulsivity moderated this effect, such that discrepancy was less predictive of disinhibited eating for those who exhibited lower levels of impulsivity. The results align with the meta-cognitive model to indicate that attitude discrepancy may be involved in overeating. © 2013.

    To understand and ultimately prevent injury and behavioural health outcomes associated with masculinity, we assessed the influence of masculine discrepancy stress (stress that occurs when men perceive themselves as falling short of the traditional gender norms) on the propensity to engage in stereotypically masculine behaviours (eg, substance use, risk taking and violence) as a means of demonstrating masculinity. Six-hundred men from the USA were recruited via Amazon's Mechanical Turk (MTurk) online data collection site to complete surveys assessing self-perceptions of gender role discrepancy and consequent discrepancy stress, substance use/abuse, driving while intoxicated (DWI) and violent assaults. Negative binomial regression analyses indicated significant interactive effects wherein men high on gender role discrepancy and attendant discrepancy stress reported significantly more assaults with a weapon (B=1.01; SE=0.63; IRR=2.74; p=0.05) and assaults causing injury (B=1.01; SE=0.51; IRR=2.74; pviolence with the greatest consequences and costs to the victim, offender and society.

    Commercial, industrial, and research interests in the Arctic are expanding rapidly. Potentials are numerous and exciting, giving rise to the need for guidelines to ensure interactions among waterway users do not conflict. Of particular concern is the potential for adverse impacts to U.S. Arctic coastal communities that rely on living marine resources for nutritional and cultural health, through subsistence hunts from small craft, ice edges, and shore. Recent events raised concerns over research surveys potentially interfering with subsistence hunts in the Bering, Chukchi, and Beaufort Seas. Incidents led to calls by Native Alaskan communities to restrict science activities with a mixed response from the scientific community (i.e., some sympathetic, some defensive). With a common goal of wanting to mitigate this potential interaction, Federal agencies made a commitment in the National Strategy for the Arctic Region to coordinate and consult with Alaska Natives and also to pursue responsible Arctic stewardship, with understanding through scientific research and traditional knowledge. The effort to create a "Standard of Care" for research surveys incorporates years of experience by subsistence hunters working to mitigate impacts of other anthropogenic activities in the region, as well as best practices by many in the research community. The protocols are designed to ensure potential conflicts between the scientific research community and subsistence hunters are avoided and to encourage mutual assistance and collaboration between researchers and hunters. The guidelines focus on enhancing communication between researchers and subsistence hunters before, during, and after research occurs. The best management practices outlined in the Standard of Care assist those overseeing and funding scientific research in making decisions about how best to accomplish the goals of the research while ensuring protection of the Alaska subsistence lifestyle. These protocols could also be

    Full Text Available Summary. At the present stage of development of economy by the main criterion of its efficiency competitiveness is. In process of involvement of Russia in world economic communications the accent in questions of competitiveness moves on the enterprises of small innovative business and to large economic entities. In this article the typology of ensuring competitiveness of small innovative and large business on the basis of forms of their interaction as one of competitiveness methodology elements is considered. The classifications of the competition and competitiveness offered by various authors that is obvious from the material given in article, have something in common with each other. Formation of the competitive relations promotes creation of the developed, civilized market that includes various spheres of managing. Thanks to active interest in problems of increase of competitiveness of subjects of small innovative and large business who arose in a consequence of development of the market relations, there was a large number of the development directed on the solution of this methodological problem. The typology of researches is one of the key moments of methodology of research. Researches can be different. It is necessary to see and understand this variety to choose the ensuring competitiveness of small innovative and large business, most suitable to process. It is possible to order all set of the most various types of researches in the table of the typological analysis. It represents dichotomizing representation of various types of ensuring competitiveness allocated by various criteria. Criteria reflect the main characteristics of research and its practical requirements. In conclusion of consideration of historical prerequisites to formation of ideas of the competition we will note that ideas of the competition evolved owing to complication of the social economic relations in society. Thus, now in social and economic space it is possible to

  7. Using Emotionally Focused Therapy to Treat Sexual Desire Discrepancy in Couples.

    2017-11-17

    Couples in committed relationships encounter a multitude of issues. According to Metz and McCarthy (2010), when couples report high sexual satisfaction, it accounts for 15% to 20% of their overall relationship satisfaction. However, when couples report low sexual satisfaction, it contributes 50% to 70% of their overall satisfaction with their partner. Issues of sexual desire, currently referred to as sexual desire discrepancy, are among the most difficult to treat. Although there are many factors contributing to the issue of sexual desire discrepancy, current literature highlights the importance of emotional intimacy as an outcome and predictor of increased sexual desire. Given the complex nature of sexual desire, clinicians often lack the understanding and treatment options that are systemic. By viewing sexual desire discrepancy as a relational problem that can be treated using emotionally focused therapy, clinicians are better equipped to work with emotional and sexual factors that impact desire and couple distress.

    Analysis of the discrepancy between intellectual functioning and memory ability has received some support as a useful means for evaluating memory impairment. In recent additions to Wechlser scale interpretation, the WAIS-III General Ability Index (GAI) and the WMS-III Delayed Memory Index (DMI) were developed. The purpose of this investigation is to develop base rate data for GAI-IMI, GAI-GMI, and GAI-DMI discrepancy scores using data from the WAIS-III/WMS-III standardization sample (weighted N = 1250). Base rate tables were developed using the predicted-difference method and two simple-difference methods (i.e., stratified and non-stratified). These tables provide valuable data for clinical reference purposes to determine the frequency of GAI-IMI, GAI-GMI, and GAI-DMI discrepancy scores in the WAIS-III/WMS-III standardization sample.

    Prior research established that simultaneously holding discrepant explicit (deliberate, controlled) and implicit (automatic, uncontrolled) self-esteem gives rise to self-enhancing behaviours. Given that individuals tend to enhance their self-concepts with brands that are associated with positive identities, this study examined whether self-esteem discrepancy was related to the extent to which individuals developed connections with brands that are associated with their in-groups. Findings from an adolescent sample (ages 16-18) indicated that adolescents with larger discrepancies between explicit and implicit self-esteem were more likely to construct their self-concepts using in-group-linked brands. © 2016 International Union of Psychological Science.

    It is currently believed that reading disability (RD) should be defined by reading level without regard to broader aptitude (IQ). There is debate, however, about how to classify individuals who read in the typical range but less well than would be expected by their higher IQ. We used functional magnetic resonance imaging (fMRI) in 49 children to examine whether those with typical, but discrepantly low reading ability relative to IQ, show dyslexia-like activation patterns during reading. Children who were typical readers with high-IQ discrepancy showed reduced activation in left temporoparietal neocortex relative to two control groups of typical readers without IQ discrepancy. This pattern was consistent and spatially overlapping with results in children with RD compared to typically reading children. The results suggest a shared neurological atypicality in regions associated with phonological processing between children with dyslexia and children with typical reading ability that is substantially below their IQ.

    With the diversification and internationalization of the food industry and the increased focus on health from a majority of consumers, food safety policies are being implemented based on scientific evidence. Risk analysis represents the most useful scientific approach for making food safety decisions. Total diet study (TDS) is often used as a risk assessment tool to evaluate exposure to hazardous elements. Many countries perform TDSs to screen for chemicals in foods and analyze exposure trends to hazardous elements. TDSs differ from traditional food monitoring in two major aspects: chemicals are analyzed in food in the form in which it will be consumed and it is cost-effective in analyzing composite samples after processing multiple ingredients together. In Korea, TDSs have been conducted to estimate dietary intakes of heavy metals, pesticides, mycotoxins, persistent organic pollutants, and processing contaminants. TDSs need to be carried out periodically to ensure food safety.

    CMS utilizes a distributed infrastructure of computing centers to custodially store data, to provide organized processing resources, and to provide analysis computing resources for users. Integrated over the whole system, even in the first year of data taking, the available disk storage approaches 10 petabytes of space. Maintaining consistency between the data bookkeeping, the data transfer system, and physical storage is an interesting technical and operations challenge. In this paper we will discuss the CMS effort to ensure that data is consistently available at all computing centers. We will discuss the technical tools that monitor the consistency of the catalogs and the physical storage as well as the operations model used to find and solve inconsistencies.

While UN Guidelines and the IADC Guidelines encourage national governments and agencies to promote debris mitigation design and operation, the ISO standards will help the global space industry promote and sustain its space-related business. In this paper the scope and status of each ISO standard is discussed within an overall framework. A comparison with international guidelines is also provided to demonstrate the level of consistency. Finally, as a case study, the ISO standards are applied to a CubeSat mission, thus demonstrating their usability on a relatively recent and popular class of satellite.

    Full Text Available A central authentication service to EPC (Electronic Product Code system architecture is proposed in our previous work. A challenge for a central service always arises that how it can ensure a certain level of delay while processing emergent data. The increasing data in the EPC system architecture is tags data. Therefore, authenticating increasing number of tag in the central authentication service with a deterministic time response is investigated and a distributed authentication service is designed in a layered approach. A distributed design of tag searching services in SOA (Service Oriented Architecture style is also presented. Using the SOA architectural style a self-adaptive authentication service over Cloud is also proposed for the central authentication service, that may also be extended for other applications.

    Patient-derived stem cells enable promising regenerative strategies, but display heterogenous cardiac reparative proficiency, leading to unpredictable therapeutic outcomes impeding practice adoption. Means to establish and certify the regenerative potency of emerging biotherapies are thus warranted. In this era of clinomics, deconvolution of variant cytoreparative performance in clinical trials offers an unprecedented opportunity to map pathways that segregate regenerative from non-regenerative states informing the evolution of cardio-regenerative quality systems. A maiden example of this approach is cardiopoiesis-mediated lineage specification developed to ensure regenerative performance. Successfully tested in pre-clinical and early clinical studies, the safety and efficacy of the cardiopoietic stem cell phenotype is undergoing validation in pivotal trials for chronic ischemic cardiomyopathy offering the prospect of a next-generation regenerative solution for heart failure.

    Most medicinal products dispensed to patients have marketing authorization (MA) to ensure high quality of the product, safety, and efficacy. However, in daily practice, to treat patients adequately, there is a medical need for drugs that do not hold MA. To meet this medical need, medicinal products are used in clinical care without MA (unlicensed), such as products prepared by (local) pharmacies: the pharmaceutical preparations. Three types of pharmaceutical preparations are distinguished: (i) reconstitution in excess of summary of product characteristics; (ii) adaptation of a licensed medicinal product (outside its official labeling); (iii) medicinal products from an active pharmaceutical ingredient. Although unlicensed, patients may expect the same quality for these unlicensed pharmaceutical preparations as for the licensed medicinal products. To assure this quality, a proper risk-benefit assessment and proper documentation in (centralized) patient registries and linking to a national pharmacovigilance database should be in place. Based on a risk assessment matrix, requirements for quality assurance can be determined, which has impact on the level of documentation of a pharmaceutical preparation. In this paper, the approach for good documentation including quality assurance and benefit-risk assessment will be discussed and possibilities for patient registries are described to make these crucial preparations available for regular patient care. KEY POINTS Ensuring pharmaceutical quality and performing a proper benefit-risk assessment will guarantee safe use of pharmaceutical preparations. Good documentation of (ultra-)orphan treatments can be collected in centralized patient registries and should be combined with existing information in (inter)national databases and self-reflection of patients. Linking patient registries to a centralized database for adverse drug events is highly recommended as it increases safety control of the (ultra) orphan pharmaceutical

  20. Ensuring grid code harmonic compliance of wind farms

    2012-07-01

    The prevalence of cabled infrastructure associated with wind farms, combined with the surge in power-electronic interfaces in wind turbines and reactive power plant, has highlighted the pervasive nature of harmonics on electricity networks. Insufficient consideration is given to the effects of harmonics through the low prioritisation of power quality in the Front-End Engineering and Design (FEED) and a lack of awareness of the obligations of the respective parties involved. The resulting designs are incompatible with the requirements of the relevant Grid Codes. This can lead to delays, commercial exposure, restricted network access and subsequent loss of revenue. The obligations of the Transmission Owner (TO), System Operator (SO), and wind farm developer are discussed with respect to Grid Code requirements and the responsibilities of each party in ensuring compliance. The technical aspects of accessing harmonic compliance are described in the context of the design considerations which are made at the various stages of the project development. These include the shift in resonances within the host network, the modification of existing harmonic distortion, and the propagation of injected harmonics into the network and through to the EHV, HV and MV substations. The ensuing challenges associated with ensuring compliance through filter design are discussed in the context of relevant international standards, including UK ER G5/4-1, IEEE 519, EN 50160 and IEC 61000-3-6. The results indicate that shifts in resonances are more problematic to resolve, compared to the propagation of injected harmonics: Injected harmonics are readily absorbed through local filtering and thus the emissions are typically low; in contrast, the affects of shifts in resonances must be transferred back to the point of common coupling, resulting in complex local filtering. Early selection by the developer of appropriate transmission infrastructure and technology can lower the filtering requirement

    Heart failure patients are regularly admitted to hospital and frequently use multiple medication. Besides intentional changes in pharmacotherapy, unintentional changes may occur during hospitalisation. The aim of this study was to investigate the effect of a clinical pharmacist discharge service on medication discrepancies and prescription errors in patients with heart failure. A general teaching hospital in Tilburg, the Netherlands. An open randomized intervention study was performed comparing an intervention group, with a control group receiving regular care by doctors and nurses. The clinical pharmacist discharge service consisted of review of discharge medication, communicating prescribing errors with the cardiologist, giving patients information, preparation of a written overview of the discharge medication and communication to both the community pharmacist and the general practitioner about this medication. Within 6 weeks after discharge all patients were routinely scheduled to visit the outpatient clinic and medication discrepancies were measured. The primary endpoint was the frequency of prescription errors in the discharge medication and medication discrepancies after discharge combined. Forty-four patients were included in the control group and 41 in the intervention group. Sixty-eight percent of patients in the control group had at least one discrepancy or prescription error against 39% in the intervention group (RR 0.57 (95% CI 0.37-0.88)). The percentage of medications with a discrepancy or prescription error in the control group was 14.6% and in the intervention group it was 6.1% (RR 0.42 (95% CI 0.27-0.66)). This clinical pharmacist discharge service significantly reduces the risk of discrepancies and prescription errors in medication of patients with heart failure in the 1st month after discharge.

  2. A STUDY OF THE DISCREPANCY BETWEEN FEDERAL AND STATE MEASUREMENTS OF ON-HIGHWAY FUEL CONSUMPTION

    Energy Technology Data Exchange (ETDEWEB)

    2003-08-11

    Annual highway fuel taxes are collected by the Treasury Department and placed in the Highway Trust Fund (HTF). There is, however, no direct connection between the taxes collected by the Treasury Department and the gallons of on-highway fuel use, which can lead to a discrepancy between these totals. This study was conducted to determine how much of a discrepancy exists between the total fuel usages estimated based on highway revenue funds as reported by the Treasury Department and the total fuel usages used in the apportionment of the HTF to the States. The analysis was conducted using data from Highway Statistics Tables MF-27 and FE-9 for the years 1991-2001. It was found that the overall discrepancy is relatively small, mostly within 5% difference. The amount of the discrepancy varies from year to year and varies among the three fuel types (gasoline, gasohol, special fuels). Several potential explanations for these discrepancies were identified, including issues on data, tax measurement, gallon measurement, HTF receipts, and timing. Data anomalies caused by outside forces, such as deferment of tax payments from one fiscal year to the next, can skew fuel tax data. Fuel tax evasion can lead to differences between actual fuel use and fuel taxes collected. Furthermore, differences in data collection and reporting among States can impact fuel use data. Refunds, credits, and transfers from the HTF can impact the total fuel tax receipt data. Timing issues, such as calendar year vs. fiscal year, can also cause some discrepancy between the two data sources.

    Studies, mostly from the operations/management literature, have shown that the rate of human error increases with task complexity. What is not known is how many errors make it into the published literature, given that they must slip by peer-review. By identifying paired, dependent values within text for reported calculations of varying complexity, we can identify discrepancies, quantify error rates and identify mitigating factors. We extracted statistical ratios from MEDLINE abstracts (Hazard Ratio, Odds Ratio, Relative Risk), their 95% confidence intervals (CIs), and their p-values. We re-calculated the ratios and p-values using the reported CIs. For comparison, we also extracted percent-ratio pairs, one of the simplest calculation tasks. Over 486,000 published values were found and analyzed for discrepancies, allowing for rounding and significant figures. Per reported item, discrepancies were less frequent in percent-ratio calculations (2.7%) than in ratio-CI and p-value calculations (5.6% to 7.5%), and smaller discrepancies were more frequent than large ones. Systematic discrepancies (multiple incorrect calculations of the same type) were higher for more complex tasks (14.3%) than simple ones (6.7%). Discrepancy rates decreased with increasing journal impact factor (JIF) and increasing number of authors, but with diminishing returns and JIF accounting for most of the effect. Approximately 87% of the 81,937 extracted p-values were ≤ 0.05. Using a simple, yet accurate, approach to identifying paired values within text, we offer the first quantitative evaluation of published error frequencies within these types of calculations. N/A.

    2017-01-01

    Full Text Available Context: Marginal discrepancy influenced by the choice of processing material used for the ceramic laminate veneers needs to be explored further for better clinical application. Aims: This study aimed to evaluate the amount of cervical and incisal marginal discrepancy associated with different ceramic laminate veneering materials. Settings and Design: This was an experimental, single-blinded, in vitro trial. Subjects and Methods: Ten central incisors were prepared for laminate veneers with 2 mm uniform reduction and heavy chamfer finish line. Ceramic laminate veneers fabricated over the prepared teeth using four different processing materials were categorized into four groups as Group I - aluminous porcelain veneers, Group II - lithium disilicate ceramic veneers, Group III - lithium disilicate-leucite-based veneers, Group IV - zirconia-based ceramic veneers. The cervical and incisal marginal discrepancy was measured using a scanning electron microscope. Statistical Analysis Used: ANOVA and post hoc Tukey honest significant difference (HSD tests were used for statistical analysis. Results: The cervical and incisal marginal discrepancy for four groups was Group I - 114.6 ± 4.3 μm, 132.5 ± 6.5 μm, Group II - 86.1 ± 6.3 μm, 105.4 ± 5.3 μm, Group III - 71.4 ± 4.4 μm, 91.3 ± 4.7 μm, and Group IV - 123.1 ± 4.1 μm, 142.0 ± 5.4 μm. ANOVA and post hoc Tukey HSD tests observed a statistically significant difference between the four test specimens with regard to cervical marginal discrepancy. The cervical and incisal marginal discrepancy scored F = 243.408, P < 0.001 and F = 180.844, P < 0.001, respectively. Conclusion: This study concluded veneers fabricated using leucite reinforced lithium disilicate exhibited the least marginal discrepancy followed by lithium disilicate ceramic, aluminous porcelain, and zirconia-based ceramics. The marginal discrepancy was more in the incisal region than in the cervical region in all the groups.

    Green, K P; Gerdeman, A

    1995-12-01

    Two experiments examined the impact of a discrepancy in vowel quality between the auditory and visual modalities on the perception of a syllable-initial consonant. One experiment examined the effect of such a discrepancy on the McGurk effect by cross-dubbing auditory /bi/ tokens onto visual /ga/ articulations (and vice versa). A discrepancy in vowel category significantly reduced the magnitude of the McGurk effect and changed the pattern of responses. A 2nd experiment investigated the effect of such a discrepancy on the speeded classification of the initial consonant. Mean reaction times to classify the tokens increased when the vowel information was discrepant between the 2 modalities but not when the vowel information was consistent. These experiments indicate that the perceptual system is sensitive to cross-modal discrepancies in the coarticulatory information between a consonant and its following vowel during phonetic perception.

    This review highlights the role of laboratory professionals and the strategies to be promoted in strict cooperation with clinicians for auditing, monitoring and improving the appropriateness of test request. The introduction of local pathways and care maps in agreement with international and national guidelines as well as the implementation of reflex testing and algorithms have a central role in guiding test request and in correcting the overuse/misuse of tests. Furthermore, removing obsolete tests from laboratory menu and vetting of restricted tests is recommended to increase cost-effectiveness. This saves costs and permits to introduce new biomarkers with increased diagnostic accuracy with a better impact on patient outcome. An additional issue is concerning the periodicity of (re)testing, accounting that only a minority of tests may be ordered as often as necessary. In the majority of cases, a minimum retesting interval should be introduced. The availability of effective computerised order entry systems is relevant in ensuring appropriate test requests and in providing an aid by automated rules that may stop inappropriate requests before they reach the laboratory.

  8. Robust mitotic entry is ensured by a latching switch

    Directory of Open Access Journals (Sweden)

    Cell cycle events are driven by Cyclin dependent kinases (CDKs and by their counter-acting phosphatases. Activation of the Cdk1:Cyclin B complex during mitotic entry is controlled by the Wee1/Myt1 inhibitory kinases and by Cdc25 activatory phosphatase, which are themselves regulated by Cdk1:Cyclin B within two positive circuits. Impairing these two feedbacks with chemical inhibitors induces a transient entry into M phase referred to as mitotic collapse. The pathology of mitotic collapse reveals that the positive circuits play a significant role in maintaining the M phase state. To better understand the function of these feedback loops during G2/M transition, we propose a simple model for mitotic entry in mammalian cells including spatial control over Greatwall kinase phosphorylation. After parameter calibration, the model is able to recapture the complex and non-intuitive molecular dynamics reported by Potapova et al. (Potapova et al., 2011. Moreover, it predicts the temporal patterns of other mitotic regulators which have not yet been experimentally tested and suggests a general design principle of cell cycle control: latching switches buffer the cellular stresses which accompany cell cycle processes to ensure that the transitions are smooth and robust.

    2009-01-01

    The life extension of the power plants is considered whereas EDF must face an acceleration of the retirement rates due to the fact that the first generations of the baby-boom are ageing 60 years, now. Between 2000 and 2006, EDF gradually set up a system of management of competencies. On the one hand, EDF moved from logic of relatively standardized training to a more individualized logic of acquisition of competencies. In addition, the objective of maintenance of internat competencies defined in 2000 was supplemented in 2003 by a prospective dimension intended to anticipate the departures in inactivity. Then in 2006 competencies of sub-contractors were taken into account. During this period I.R.S.N. has assessed 3 times this system of management. This article briefly presents the principal lessons driven from these evaluations. It accounts for the undeniable effort made by EDF to ensure the maintenance of its competencies. However, it stresses that a high level of vigilance is still needed because it is not stabilized already. (author)

    Egg shell sanitizing practices are necessary to improve microbiological safety of fresh eggs. In this work, fifteen fresh eggs samples of each (Balady, White and Brown eggs) were collected from different local supermarkets to evaluate their microbiological quality. The results indicated that Balady eggs were higher in microbial population in comparison with the two other varieties. Salmonella spp. was detected in 9 (60%) samples of Balady eggs. The effect of gamma irradiation at dose of 0, 2, 3 and 4 kGy on microbiological quality of Balady eggs during storage at 4±1 degree C for 35 days was studied. The effects of irradiation and storage on total cholesterol, and total carotenoids contents in Balady eggs were also investigated. The results showed that irradiation at 3 kGy reduced total aerobic bacterial counts. Coliform bacteria, E. coli and Salmonella spp. were completely eliminated. Total cholesterol and total carotenoids were decreased in yolk egg as a result of irradiation. Treated Balady eggs with irradiation dose of 3 kGy were efficient and sufficient for ensuring safety, maintain quality and extend shelf-life.

  11. Failure assessment techniques to ensure shipping container integrity

    International Nuclear Information System (INIS)

    McConnell, P.

    1986-02-01

    This report discusses several methodologies which may be used to ensure the structural integrity of containment systems to be used for the transport and storage of high-level radioactive substances. For economic reasons, shipping containers constructed of ferritic materials are being considered for manufacture by vendors in the US and Europe. Ferritic show an inherent transition from a ductile, high energy failure mode to a brittle, low energy fracture mode with decreasing temperature. Therefore, formal consideration of means by which to avoid unstable brittle fracture is necessary prior to the licensing of ferritic casks. It is suggested that failure of a shipping container wall be defined as occurring when a flaw extends through the outer wall of the containment system. Crack initiation which may lead to unstable brittle crack growth should therefore be prevented. It is suggested that a fundamental linear elastic fracture mechanics (lefm) approach be adopted on a case-by-case basis, applied perhaps by means of appropriate modifications to ASMA Section III or Section XI. A lefm analysis requires information concerning service temperatures, loading rates, flaw sizes, and applied stresses. Tentative judgments regarding these parameters for typical shipping containers have been made

  13. Role of primary health care in ensuring access to medicines.

    2010-06-01

    To examine ways of ensuring access to health services within the framework of primary health care (PHC), since the goal of PHC to make universal health care available to all people has become increasingly neglected amid emerging themes of globalization, trade, and foreign policy. From a public health point of view, we argue that the premise of PHC can unlock barriers to health care services and contribute greatly to determining collective health through the promotion of universal basic health services. PHC has the most sophisticated and organized infrastructure, theories, and political principles, with which it can deal adequately with the issues of inequity, inequality, and social injustice which emerge from negative economic externalities and neo-liberal economic policies. Addressing these issues, especially the complex social and political influences that restrict access to medicines, may require the integration of different health initiatives into PHC. Based on current systems, PHC remains the only conventional health delivery service that can deal with resilient public health problems adequately. However, to strengthen its ability to do so, we propose the revitalization of PHC to incorporate scholarship that promotes human rights, partnerships, research and development, advocacy, and national drug policies. The concept of PHC can improve access; however, this will require the urgent interplay among theoretical, practical, political, and sociological influences arising from the economic, social, and political determinants of ill health in an era of globalization.

    2013-09-01

    Full Text Available The field of qualitative scientific inquiry employs a fast-growing variety of approaches, whose traditions, procedures, and structures vary, depending on the type of study design and methodology (i.e., phenomenological, ethnographic, grounded theory, case study, action research, etc.. With the interpretive approach, researchers do not utilize the same measures of validity used in positivist approaches to scientific inquiry, since there is "...no one standard or accepted structure as one typically finds in quantitative research" (Creswell, 2007. With the absence of a single standard, how, then, is it possible for qualitative researchers to know whether or not their study was done with rigor, that it has validity, that it is ready to submit to their peers? The research literature is sprinkled with references to quality in qualitative inquiry, which helps to construe a study's validity. Markula (2008 suggests that we validate our study's findings by assuring readers that it was done "in the best possible way." While each research tradition has its own set of criteria for judging quality, we present here general concepts drawn from the literature. We hope this article will provide a framework from which qualitative researchers can judge their work before submitting it to their peers¸ one which will help ensure that their study was done "in the best possible way."

    2016-01-01

    In their daily forensic casework, the authors experienced discrepancies of tracheobronchial content findings between postmortem computed tomography (PMCT) and autopsy to an extent previously unnoticed in the literature. The goal of this study was to evaluate such discrepancies in routine forensic cases. A total of 327 cases that underwent PMCT prior to routine forensic autopsy were retrospectively evaluated for tracheal and bronchial contents according to PMCT and autopsy findings. Hounsfield unit (HU) values of tracheobronchial contents, causes of death, and presence of pulmonary edema were assessed in mismatching and matching cases. Comparing contents in PMCT and autopsy in each of the separately evaluated compartments of the respiratory tract low positive predictive values were assessed (trachea, 38.2%; main bronchi, 40%; peripheral bronchi, 69.1%) indicating high discrepancy rates. The majority of tracheobronchial contents were viscous stomach contents in matching cases and low radiodensity materials (i.e., HU autopsy occur in a considerable number of cases. Discrepancies may be explained by the runoff of contents via nose and mouth during external examination and the flow back of tracheal and main bronchial contents into the lungs caused by upright movement of the respiratory tract at autopsy.

    Full Text Available Determination of hepatitis C virus (HCV genotypes plays an important role in the direct-acting agent era. Discrepancies between HCV genotyping and serotyping assays are occasionally observed. Eighteen samples with discrepant results between genotyping and serotyping methods were analyzed. HCV serotyping and genotyping were based on the HCV nonstructural 4 (NS4 region and 5′-untranslated region (5′-UTR, respectively. HCV core and NS4 regions were chosen to be sequenced and were compared with the genotyping and serotyping results. Deep sequencing was also performed for the corresponding HCV NS4 regions. Seventeen out of 18 discrepant samples could be sequenced by the Sanger method. Both HCV core and NS4 sequences were concordant with that of genotyping in the 5′-UTR in all 17 samples. In cloning analysis of the HCV NS4 region, there were several amino acid variations, but each sequence was much closer to the peptide with the same genotype. Deep sequencing revealed that minor clones with different subgenotypes existed in two of the 17 samples. Genotyping by genome amplification showed high consistency, while several false reactions were detected by serotyping. The deep sequencing method also provides accurate genotyping results and may be useful for analyzing discrepant cases. HCV genotyping should be correctly determined before antiviral treatment.

    Full Text Available This study aimed to characterize dieting and non-dieting university students by gender, based on their satisfaction with life and their food-related life, self-discrepancy, food behavior and health-related aspects. A non-probabilistic sample of 305 students from five Chilean state universities responded a questionnaire that included the Revised Restraint Scale, the Satisfaction with Life Scale, the Satisfaction with Food-related Life Scale, the Health-related Quality of Life Index, the Nutrition Interest Scale and the Self-Discrepancy Index. Socio-demographic characteristics, food behavior, and approximate weight and height were also enquired. Chronic dieters and non-dieters were distinguished according to the median score of the Revised Restraint Scale. 51.1% of women and 55.5% of men classified as chronic dieters, sharing characteristics such as nutrition concern, mental health problems, higher body mass index, and physical and economic self-discrepancy. Women dieters reported lower life satisfaction and satisfaction with food-related life, more health problems and health-related restriction of food, while men dieters showed higher social and emotional self-discrepancy.

    On the basis of an extension of Self-Discrepancy Theory (SDT) to the social aspect of the self (A. Bizman, Y. Yinon, & S. Krotman, 2001), the authors examined the relationships between social self-discrepancies from own and other standpoints and collective self-esteem. The authors assessed perceptions of actual, ideal, and ought attributes of Israelis from own and other standpoints; perceived importance of others' evaluation of Israel; and the Collective Self-Esteem Scale (CSES) among 114 Israelis. The results revealed that the association of the discrepancy between actual Israelis and ideal Israelis from the other standpoint with the public Collective Self-Esteem (CSE) subscale was negative among participants with high perceived importance and positive among those with low perceived importance. In addition, the discrepancy between actual and ideal Israelis from the own standpoint was related to the private, public, and membership CSE subscales. Overall, the findings suggest that the SDT distinction between the own and other standpoints on the self is applicable to the social self.

    Developing discrepancy between one's values and behaviors is theoretically important in motivating change; however, existing studies lack a validated measure of value-behavior discrepancy for alcohol misuse. The current studies aimed to modify Wilson & DuFrene (2008) Valued Living Questionnaire (VLQ) to assess consistency of alcohol use with important values. In Study 1, the initial factor structure and test-retest reliability of the VLQ for Alcohol Use (VLQ-A) was tested in a sample of college students who regularly drink alcohol (N = 150). Results guided modifications to the measure. In Study 2, the revised measure's factor structure and predictive validity were tested with a second sample of college students who drink alcohol (N = 222). In both studies, exploratory factor analysis supported a unidimensional factor structure. Perceived discrepancy between alcohol use and important values predicted greater readiness to change, while perceived consistency between alcohol use and important values predicted more frequent heavy episodic drinking. Certain values were more useful in predicting outcomes than others. Alcohol use (heavy vs. moderate drinking) did not moderate outcomes. The VLQ-A is a brief and reliable self-report measure of perceived discrepancy between drinking behaviors and important values that may increase readiness to change. Future research examining the generalizability of findings to various samples and the efficacy of the VLQ-A as a supplement to brief interventions is warranted.

    The literature on chronic diseases indicates that partner support, as perceived by patients, contributes to well-being of patients in either a positive or a negative way. Previous studies indicated that patients' and partners' perceptions of unsupportive partner behavior are only moderately related. Our aim was (1) to investigate whether discrepancies between patients' and partners' perceptions of two types of unsupportive partner behavior-overprotection and protective buffering-were associated with the level of distress reported by patients with chronic obstructive pulmonary disease (COPD) and (2) to evaluate whether the direction of the differences between patients' and partners' perceptions was associated with distress (i.e., whether patient distress was associated with greater patient or greater partner reports of unsupportive partner behavior). A cross-sectional study was performed using the data of a sample of 68 COPD patients and their spouses. Distress was assessed using the Hopkins Symptom Checklist-25. Patients' and partners' perceptions of unsupportive partner behavior were assessed with a questionnaire measuring overprotection and protective buffering. Distress was independently associated with patients' perceptions of protective buffering and discrepancies in spouses' perceptions of overprotection. Regarding the direction of the discrepancy, we found that greater partner reports of overprotection as compared with patient reports were related to more distress in COPD patients. Our study showed that patients' distress was associated not only with patients' perceptions, but also with discrepancies between patients' and partners' perceptions of unsupportive partner behavior.

    2003-01-01

    This study examines possible parent-child discrepancies in the reporting of post-traumatic stress reactions in children after a traffic accident. Sixteen children exposed to the same traffic accident were interviewed about post-traumatic stress reactions at 5 weeks and at 6 months after the event, utilizing the Child Posttraumatic Stress Reaction Index (CPTS-RI). Independently, the parents' reported their child's degree of post-traumatic stress reactions on the CPTS-RI: Parent questionnaire, at the same two times. Clinicians also assessed the children's level of general functioning on the Children's Global Assessment Scale. The children reported significantly more post-traumatic stress reactions than observed by their parents 4 weeks after the accident. The parent-child discrepancy was more pronounced among younger children. The level of children's self-reported post-traumatic stress reactions decreased significantly from the first to the second assessment. At the second assessment, 6 months after the accident, there was no significant parent-child discrepancy observed. The children showed a normal level of functioning despite their post-traumatic stress reactions. The reported parent-child discrepancy indicates that information about children's post-traumatic stress reactions after an accident is best obtained directly from the children.

    2010-08-01

    Recurrent pain not only has an impact on disability, but on the long term it may become a threat to one's sense of self. This paper presents a cross-sectional study of patients with work-related upper extremity pain and focuses on: (1) the role of self-discrepancies in this group, (2) the associations between self-discrepancies, pain, emotions and (3) the interaction between self-discrepancies and flexible-goal adjustment. Eighty-nine participants completed standardized self-report measures of pain intensity, pain duration, anxiety, depression and flexible-goal adjustment. A Selves Questionnaire was used to generate self-discrepancies. A series of hierarchical regression analyses showed relationships between actual-ought other, actual-ought self, actual-feared self-discrepancies and depression as well as a significant association between actual-ought other self-discrepancy and anxiety. Furthermore, significant interactions were found between actual-ought other self-discrepancies and flexibility, indicating that less flexible participants with large self-discrepancies score higher on depression. This study showed that self-discrepancies are related to negative emotions and that flexible-goal adjustment served as a moderator in this relationship. The view of self in pain and flexible-goal adjustment should be considered as important variables in the process of chronic pain.

    To examinehow study volume affects discrepancy rates for on-call radiology residents. Inparticular, we studied how both total shift volume and volume at a particularpoint in time might effect performance. Weretrospectively analyzed 518 weekend call shifts at our institution. The totalnumber of computed tomography (CT) studies per shift was recorded. For everyabdomen-pelvis (AP) or chest-abdomen-pelvis (CAP) CT, preliminary and finalreports were compared for possible discrepancy and rated (by effect on short-termmanagement). We also developed "peristudy volume," defined as CTs read within ±30minutes of a given CT, an estimate of how busy a resident might be at a giventime. We performed logistic regressions to determine whether overall shiftvolume or peristudy volume were predictors of discrepancies. CTvolume/day increased from 58.1 ± 10.1 in 2011 to 75.3 ± 12.5 in 2015(p<0.001). 4695 AP (or CAP) CTs were reviewed, with 145 discrepancies thatcould affect short-term management (3.1%). When reading a study during a shift with≥51 total CTs,residents had increased odds of an error compared to reading a study during ashift with ≤30 studies (OR: 2.97, CI: 1.19-6.46) (p=0.01). When reading a CTwith a peristudy volume of ≥6, residents had increased odds of an error comparedto reading a study with ≤5 peristudy CTs (OR: 1.6, CI: 1.1-2.3) (p=0.01). Whenon-call residents interpret AP CT during high volume shiftsor during busy time-points, odds of discrepancies increase. Awareness of thesedata may inform residency programs in staffing decisions.

    Mathematics is associated with anxiety for many students; an emotion linked to lower well-being and poorer learning outcomes. While findings typically show females to report higher trait math anxiety than males, no gender differences have to date been found in state (i.e., momentary) math anxiety. The present diary study aimed to replicate previous findings in investigating whether levels of academic self-concept was related to this discrepancy in trait vs. state anxiety measures. Additionally, mathematics-related gender stereotype endorsement (mathematics is a male domain) was investigated as an additional predictor of the trait-state discrepancy. The sample included 755 German 9th and 10th graders who completed self-report measures of trait math anxiety, math self-concept, and gender stereotype endorsement, in addition to state measures of anxiety after math classes by use of a standardized diary for 2-3 weeks (N within = 6207). As expected, females reported higher trait math anxiety but no gender differences were found for state math anxiety. Also in line with our assumptions, multilevel analyses showed the discrepancy between trait and state anxiety to be negatively related to students' self-concept (i.e., a lower discrepancy for students with higher self-concepts). Furthermore, gender stereotype endorsement differentially predicted the trait-state discrepancy: When controlling for self-concept in mathematics, females who endorsed the gender stereotype of math being a male domain more strongly overestimated their trait math anxiety as compared to their state anxiety whereas this effect was not significant for males. The present findings suggest that gender stereotype endorsement plays an important role in explaining gender differences in math anxiety above and beyond academic self-concept. Implications for future research and educational practice are discussed.

  5. The amplitude of the Love-Rayleigh discrepancy created by small-scale heterogeneities

    2002-07-01

    At global as well as at regional scale, the lithosphere appears faster to Love waves than to Rayleigh waves. This Love-Rayleigh discrepancy can be modelled by introducing transverse isotropy in the upper mantle. In some regions however, it is so large that the question arises as to whether part of it could be an artefact related to the presence of heterogeneities in the lithosphere. Using a multiple-scattering scheme to model surface waves in 3-D structures, we analyse the influence of small-scale heterogeneities in the lithosphere on the Love-Rayleigh discrepancy in the period range 25 to 60 s. Small-scale heterogeneities tend to lower the apparent phase velocity of the surface waves, and have a larger effect on the Love waves than on the Rayleigh waves. This is not due to mode-coupling, which plays a negligible role here, but to the interference of the primary field with the one backscattered twice. For models with S-wave velocity variations of rms 2.5 per cent, and spatial correlations at distances of 20 to 100 km, we find that the Love waves are on average and at most 0.1 per cent slower than the Rayleigh waves. This apparent Love-Rayleigh discrepancy varies linearly with the variance of S-wave velocity variation in the structure. We conclude that small-scale heterogeneities do not contribute significantly to the large Love-Rayleigh discrepancies of 4 to 9 per cent observed in some regions, since they produce an apparent discrepancy which is negligible in comparison, and which even has the opposite sign.

    2015-02-01

    From July to August 2014, Epilepsia conducted an online survey seeking opinions that explained the discrepancy between the incidence and prevalence of epilepsy in lower income countries. Data on cumulative incidence suggest a higher rate of active epilepsy than reported in lifetime prevalence surveys. This study reports the findings of that poll addressing the proposal in our Controversy in Epilepsy series that it could be from increased death rates. The survey consisted of a question addressing possible reasons to explain the discrepancy between the incidence and prevalence of epilepsy. Another four questions addressed demographic information. There were 34 responders who completed the survey. Half (50%) of the responders felt that the discrepancy between cumulative incidence and lifetime prevalence was due to lack of uniform definitions and misclassification of patients in study design, 23.5% said the discrepancy was due to a higher mortality from diseases and conditions such as trauma and infections associated with epilepsy, 23.5% indicated that the stigma of epilepsy prevented people from acknowledging their disease in prevalence surveys, and 2.9% felt it was from poor access to qualified medical personal and utilization of medical treatments that increased death rates directly related to epilepsy. Within the limitations of sample size, the results of this survey support that the discrepancy between the incidence and prevalence of epilepsy in lower income regions of the world is due to problems in acquiring the data and stigma rather than higher mortality from diseases associated with epilepsy and repeated seizures.

    Purpose Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Methods Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Results Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Conclusions Boys who experience stress about being perceived as “sub-masculine” may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential “threats” to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

    Full Text Available Indian health system is characterized by a vast public health infrastructure which lies underutilized, and a largely unregulated private market which caters to greater need for curative treatment. High out-of-pocket (OOP health expenditures poses barrier to access for healthcare. Among those who get hospitalized, nearly 25% are pushed below poverty line by catastrophic impact of OOP healthcare expenditure. Moreover, healthcare costs are spiraling due to epidemiologic, demographic, and social transition. Hence, the need for risk pooling is imperative. The present article applies economic theories to various possibilities for providing risk pooling mechanism with the objective of ensuring equity, efficiency, and quality care. Asymmetry of information leads to failure of actuarially administered private health insurance (PHI. Large proportion of informal sector labor in India′s workforce prevents major upscaling of social health insurance (SHI. Community health insurance schemes are difficult to replicate on a large scale. We strongly recommend institutionalization of tax-funded Universal Health Insurance Scheme (UHIS, with complementary role of PHI. The contextual factors for development of UHIS are favorable. SHI schemes should be merged with UHIS. Benefit package of this scheme should include preventive and in-patient curative care to begin with, and gradually include out-patient care. State-specific priorities should be incorporated in benefit package. Application of such an insurance system besides being essential to the goals of an effective health system provides opportunity to regulate private market, negotiate costs, and plan health services efficiently.

    Self-esteem (SE), or one's sense of competence and worth, is reduced in many mental and physical disorders. Low SE is associated with perceived stigma and disability and poor treatment outcomes. The present study examined implicit and explicit SE (automatic and deliberate views about the self) in people with epilepsy and people with psychogenic nonepileptic seizures (PNESs). Discrepancies between implicit SE and explicit SE have been found to correlate with psychological distress in disorders often associated with PNESs but are relatively unexplored in PNESs. We hypothesized that, compared with epilepsy, PNESs would be associated with lower self-reported SE and greater discrepancies between implicit SE and explicit SE. Thirty adults with PNESs, 25 adults with epilepsy, and 31 controls without a history of seizures were asked to complete the Rosenberg Self-esteem Scale as a measure of explicit SE and an Implicit Relational Assessment Procedure as a measure of implicit SE. The State-Trait Anxiety Inventory and Patient Health Questionnaire-15 (a somatic symptom inventory) were also administered. We found significant group differences in explicit (p<0.001) but not implicit SE. Patients with PNESs reported lower SE than the other groups. No group differences were found in implicit SE. Implicit-explicit SE discrepancies were larger in the group with PNESs than in the other groups (p<0.001). Higher frequency of PNESs (but not epileptic seizures) was associated with lower explicit SE (rs=-.83, p<0.01) and greater SE discrepancies (i.e., lower explicit relative to implicit SE; rs=.65, p<0.01). These relationships remained significant when controlling for anxiety and somatization. Patients with PNESs had lower explicit SE than those with epilepsy or healthy controls. In keeping with our expectations, there were greater discrepancies between implicit SE and explicit SE among patients with PNESs than in the other groups. Our results, including the strong relationship between

    Describe the types of medication discrepancies that persist despite pharmacist-led medication reconciliation using the primary care electronic medical record (EMR). Observational case series study of established patients from an urban, indigent care clinic. Medication reconciliation was conducted immediately prior to the physician visit at baseline and return visit. Main outcome measures included: frequency, types, and reasons for discrepancies, patient knowledge, and adherence. There was a 14.5% reduction in the number of patients with a discrepancy and the frequency of discrepancies was reduced by 7.3%. The rate of medication discrepancies in the chart was reduced by 31.3%. The most common type of discrepancy that persisted at follow up were medications listed on the chart that the patient stopped taking. Discrepancies were more likely to persist in Caucasian subjects when compared to African Americans. While pharmacist led medication reconciliation appears effective at reducing the likelihood of a medication discrepancy in the EMR, challenges persist in maintaining this accuracy specifically as it relates to patient driven changes to the medication regimen.

  20. Global Uranium Supply Ensured for Long Term, New Report Shows

    International Nuclear Information System (INIS)

    2012-01-01

    Full text: Uranium resources and production are on the rise with the security of uranium supply ensured for the long term, according to a new report by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). Uranium 2011: Resources, Production and Demand, commonly referred to as the ''Red Book'', shows that total identified uranium resources have grown 12.5% since 2008. However, the costs of production have also increased, leading to reductions in lower cost category resources. These figures, which reflect the situation as of 1 January 2011, mean that total identified resources are sufficient for over 100 years of supply based on current requirements. Global uranium mine production increased by over 25% between 2008 and 2010 because of significantly increased production in Kazakhstan, currently the world's leading producer. The increased resource base has been achieved thanks to a 22% increase in uranium exploration and mine development expenditures between 2008 and 2010, which in 2010 totalled over $2 billion. Demand for uranium is expected to continue to rise for the foreseeable future. Although the Fukushima Daiichi nuclear accident has affected nuclear power projects and policies in some countries, nuclear power remains a key part of the global energy mix. Several governments have plans for new nuclear power plant construction, with the strongest expansion expected in China, India, the Republic of Korea and the Russian Federation. The speed and magnitude of growth in generating capacity elsewhere is still to be determined. By the year 2035, according to the joint NEA-IAEA Secretariat, world nuclear electricity generating capacity is projected to grow from 375 GWe net (at the end of 2010) to between 540 GWe net in the low demand case and 746 GWe net in the high demand case, increases of 44% and 99% respectively. Accordingly, world annual reactor-related uranium requirements are projected to rise from 63 875 tonnes of uranium metal

  1. Discrepancy between self- and observer ratings of performance in social phobics.

    1992-11-01

    Twenty-eight subjects meeting Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; American Psychiatric Association, 1987) criteria for social phobia and without a comorbid affective disorder and 33 nonclinical controls were asked to present a brief, impromptu speech to a small audience. Speakers themselves, as well as members of the audience, rated each speaker on a public speaking questionnaire that included both specific items (e.g., voice shook) and global items (e.g., appeared confident). For global items, no significant difference was indicated between the two groups on observers' ratings of public speaking performance. However, social phobics rated their own performance worse than did nonclinical controls, and there was a significantly greater discrepancy between self and other ratings for social phobics than controls. Fear of negative evaluation was the only significant predictor of the self-other discrepancy on global items.

    Computer-aided design and computer-aided manufacturing (CAD-CAM) high-density polymers (HDPs) have recently been marketed for the fabrication of long-term interim implant-supported fixed prostheses. However, information regarding the precision of fit of CAD-CAM HDP implant-supported complete-arch screw-retained prostheses is scarce. The purpose of this in vitro study was to evaluate the marginal discrepancy of CAD-CAM HDP complete-arch implant-supported screw-retained fixed prosthesis frameworks and compare them with conventional titanium (Ti) and zirconia (Zir) frameworks. A screw-retained complete-arch acrylic resin prototype with multiunit abutments was fabricated on a typodont model with 2 straight implants in the anterior region and 2 implants with a 30-degree distal tilt in the posterior region. A 3-dimensional (3D) laboratory laser scanner was used to digitize the typodont model with scan bodies and the resin prototype to generate a virtual 3D CAD framework. A CAM milling unit was used to fabricate 5 frameworks from HDP, Ti, and Zir blocks. The 1-screw test was performed by tightening the prosthetic screw in the maxillary left first molar abutment (terminal location) when the frameworks were on the typodont model, and the marginal discrepancy of frameworks was evaluated using an industrial computed tomographic scanner and a 3D volumetric software. The 3D marginal discrepancy at the abutment-framework interface of the maxillary left canine (L1), right canine (L2), and right first molar (L3) sites was measured. The mean values for 3D marginal discrepancy were calculated for each location in a group with 95% confidence limits. The results were analyzed by repeated-measures 2-way ANOVA using the restricted maximum likelihood estimation and the Satterthwaite degrees of freedom methods, which do not require normality and homoscedasticity in the data. The between-subjects factor was material, the within-subjects factor was location, and the interaction was

    During the recent entry of the Mars Science Laboratory (MSL), the heat shield was equipped with thermocouple stacks to measure in-depth heating of the thermal protection system (TPS). When only convective heating was considered, the derived heat flux from gauges in the stagnation region was found to be underpredicted by as much as 17 W/sq cm, which is significant compared to the peak heating of 32 W/sq cm. In order to quantify the contribution of radiative heating phenomena to the discrepancy, ground tests and predictive simulations that replicated the MSL entry trajectory were performed. An analysis is carried through to assess the quality of the radiation model and the impact to stagnation line heating. The impact is shown to be significant, but does not fully explain the heating discrepancy.

    This study examined the association between relationship adjustment and discrepant alcohol use among lesbian women and their same-sex intimate partners after controlling for verbal and physical aggression. Lesbian women ( N = 819) who were members of online marketing research panels completed an online survey in which they reported both their own and same-sex intimate partner's alcohol use, their relationship adjustment, and their own and their partner's physical aggression and psychological aggression (i.e., verbal aggression and dominance/isolation). Partners' alcohol use was moderately correlated. Discrepancy in alcohol use was associated with poorer relationship adjustment after controlling for psychological aggression and physical aggression. Results are discussed in terms of the similarity and differences with previous literature primarily focused on heterosexual couples.

    The Jknun (Jk-3) phenotype, attributable to null or silenced alleles, has predominantly been found in persons of Polynesian descent. With the increased use of molecular genotyping, many new silencing mutations have been identified in persons of other ethnic backgrounds. To date, only two JK null alleles have been reported in African Americans, JK*01N.04 and JK*OlN.OS.A comparative study was undertaken to determine whether JK mutations were present in the regional African American population. Results of donor genotyping were compared with previously recorded results of serologic tests, and discrepant results were investigated. Although the two previously identified polymorphisms were not detected in the discrepant samples, a novel allele (191G>A) was identified and was assigned the ISBT number JK*02N.09. This study illustrates a limitation of using single-nucleotide polymorphisms for prediction of blood group antigens.

    Body dissatisfaction, the negative subjective evaluation of one's body, is associated with many negative psychological and physical health consequences. One conceptualization of body dissatisfaction includes an experience of discrepancy between perceived actual and ideal body shapes. This paper reviews the literature on three facets of body dissatisfaction from the framework of self-discrepancy theory: perceptions of current weight, ideal body weight, and the relative importance of conforming to ideals. We review components of body dissatisfaction among healthy individuals and eating-disordered individuals. We also address the conceptualization's relationship among body dissatisfaction, weight history, and dieting to expand the impact of body dissatisfaction research and to provide more information on the nature and treatment of eating disorders.

  8. Facts and Findings on the Statistical Discrepancies of the Korean Balance of Payments

    Directory of Open Access Journals (Sweden)

    2000-03-01

    Full Text Available The Korea experienced drastic increases in the statistical discrepancy in balance of payments since 1997. In general, the expansion and complexity of external transactions induced by contributing capital account liberalization has contributed to this fact. The abolition of the export/import approval system seems to have accelerated the mismeasurement and omissions in external transactions. Of course, the influence of currency crisis occurred cannot be ruled out. Among economic factors, Won/dollar exchange rate volatility is found to have significant explanatory power on the magnitude of statistical discrepancy, while exchange rate returns have not. WE interpret this as the demand for relatively safe currency rising in presence of the uncertainty in domestic currency values.

    This article examined the role of caregiver messages about violence and exposure to neighborhood violence on adolescent aggression in light of research regarding discrepancies between parents and their children. Drawing upon data from an urban African American sample of 144 caregiver/early adolescent dyads (M = 12.99; SD = 0.93; 58.7 % female) we examined covariates of discrepancies between caregiver and adolescent reports of perceptions of violence as well as their association with adolescent aggression. Analyses suggested that concordance in perceptions of violence was associated with children's attitudes about violence and caregivers' perceptions of family communication. Structural equation modeling indicated a unique role for individual perceptions and suggested that agreement in awareness of neighborhood violence could be protective for early adolescent involvement in aggression.

    We apply two different methods to the calculation of the triply differential cross section (TDCS) for double ionization of helium. In one method, the 3C method, the final state is described by a product of 3 Coulomb continuum wave functions, while in the other method, the 2SC method, the final state is described by a product of 2 {ital screened} Coulomb wave functions employing effective charges. We present results at the energies and geometries covered in the recent experiment by Lablanquie {ital et} {ital al}. [Phys. Rev. Lett. {bold 74}, 2192 (1995)]. There are substantial discrepancies. We also comment on a recent measurement of the {ital absolute} TDCS by Schwarzkopf and Schmidt [J. Phys. B {bold 28}, 2847 (1995)]. The measured result, as originally reported, is a factor of two smaller than the value for the absolute TDCS calculated using the 2SC method. We discuss this discrepancy. {copyright} {ital 1996 The American Physical Society.}

    Discrepancies between implicit and explicit self-esteem have been linked with internalizing problems among mainly adolescents and adults. Longitudinal research on this association in children is lacking. This study examined the longitudinal link between self-esteem discrepancies and the development of internalizing problems in children. It furthermore examined the possible mediating role of self-esteem discrepancies in the longitudinal link between experiences of peer victimization and internalizing problems development. Children (N = 330, M(age) = 11.2 year; 52.5 % female) were followed over grades five (age 11 years) and six (age 12 years). Self-report measures were used annually to test for victimization and internalizing problems. Implicit self-esteem was assessed using an implicit association test, while explicit self-esteem was assessed via self-reports. Self-esteem discrepancies represented the difference between implicit and explicit self-esteem. Results showed that victimization was associated with increases in damaged self-esteem (higher levels of implicit than explicit self-esteem. Additionally, damaged self-esteem at age 11 years predicted an increase in internalizing problems in children over ages 11 to 12 years. Furthermore, damaged self-esteem mediated the relationship between age 11 years victimization and the development of internalizing problems. No impact of fragile self-esteem (lower levels of implicit than explicit self-esteem) on internalizing problems was found. The results thus underscore that, as found in adolescent and adult samples, damaged self-esteem is a predictor of increases in childhood internalizing problems. Moreover, damaged self-esteem might explain why children who are victimized develop internalizing problems. Implications are discussed.

    Previous studies have found high implicit self-esteem (ISE) to prevail concurrently with low explicit self-esteem (ESE) in socially anxious adults. This suggests that self-esteem discrepancies are associated with social anxiety disorder (SAD). Given that the onset of SAD often occurs in adolescence, we investigated self-esteem discrepancies between ISE and ESE in adolescents suffering from SAD. Two implicit measures (Affect Misattribution Procedure, Implicit Association Test) were used both before and after a social threat activation in 20 adolescents with SAD (14-20 years), and compared to 20 healthy adolescents who were matched for age and gender. The Rosenberg Self-Esteem Scale, the Social Cognitions Questionnaire and Beck Depression Inventory were administered as explicit measures. We expected discrepant self-esteem (high ISE, low ESE) in adolescents with SAD, in comparison to congruent self-esteem (positive ISE, positive ESE) in healthy controls, after social threat activation. Both the patient and control groups exhibited high positive ISE on both implicit measures, before as well as after social threat induction. Explicitly, patients suffering from SAD revealed lower levels of ESE, compared to the healthy adolescents. This study is the first to examine ISE and ESE in a clinical sample of adolescent patients with SAD. Our results suggest that SAD is associated with a discrepancy between high ISE and low ESE, after a social-threat manipulation. The findings are discussed in relation to other studies using implicit measures in SAD and may provide a more comprehensive understanding of the role of self-esteem in adolescent SAD.

    2017-09-01

    Controversy still exists as to the clinical significance of leg length discrepancy (LLD) in spite of the fact that further evidence has been emerging regarding the relationship between several clinical conditions and LLD. The objectives of our study were to review the available research with regard to LLD as a cause of clinically significant gait deviations, to determine if there is a relationship between the magnitude of LLD and the presence of gait deviations and to identify the most common gait deviations associated with LLD. In line with the PRISMA guidelines, a literature search was carried out throughout the Medline, CINAHL and EMBASE databases. Twelve articles met the predetermined inclusion criteria and were included in the review. Quality assessment using the Methodological Index for Non-Randomized Studies (MINORS) scale was completed for all included studies. Two main methodologies were found in 4 studies evaluating gait asymmetry in patients or healthy participants with anatomic LLD and 8 studies evaluating gait deviations while simulating LLD by employing artificial lifts of 1-5cm on healthy subjects. A significant relationship was found between anatomic LLD and gait deviation. Evidence suggests that gait deviations may occur with discrepancies of >1cm, with greater impact seen as the discrepancy increases. Compensatory strategies were found to occur in both the shorter and longer limb, throughout the lower limb. As the discrepancy increases, more compensatory strategies occur. Sagittal plane deviations seem to be the most effective deviations, although, frontal plane compensations also occur in the pelvis, hip and foot. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study examines the frequency of discrepancy between Kt/V urea and creatinine clearance (Ccr) measurements in patients on peritoneal dialysis (PD) and the reasons for this discrepancy. Nonrandomized, retrospective data analysis. Single PD unit of a university teaching hospital. All adult patients receiving PD at our center from January 1995 to December 1996. Actual (a) and desired (d) body weight (BW) were used to calculate urea volume of distribution (V) and body surface area (BSA). Patients were divided into four groups based upon their total small solute clearances (Kt/V and Ccr, normalized by actual weight) and three additional groups based upon actual/desired (a/d) body weight ratio. An additional analysis was performed for the subset of anuric patients. Data collected for all patients included the following: total Kt, total Ccr, 4-hour dialysate/ plasma (D/P) creatinine, serum albumin concentration, duration of PD, actual body weight, age, and height. Twenty-three percent of the clearance measurements in our study were discrepant, defined as having values for either Kt/V or Ccr (but not both) above the accepted targets of Kt/V > or = 2.0/wk and Ccr > or = 60 L/wk/ 1.73 m2. Patients with both values above target are more likely to have higher residual renal function. Patients who are significantly less than BWd and patients on PD for a longer time are more likely to have adequate Kt/V but not Ccr. Furthermore, patients who are less than 90% or greater than 110% of BWd have markedly different values for Kt/V and Ccr when BWa versus BWd values are used. Kt/V and Ccr values are frequently discrepant; a number of factors affect these two measurements to varying degrees, including weight, degree of residual renal function, and duration of PD.

In order to explore the scope of their deficits, it is of great interest to compare the different interpersonal skills and executive functions of ASD subjects to those of children with typical development. Assessing these skills usually involves a large variety of informants (parents, teachers, other family members) and of measures, with frequent discrepancies between direct performance measures and indirect measures (third-party report). Different explanations of this mismatch between measures have been addressed in previous studies. We wish to analyze whether there are differences between children with ASD and children with typical development on several direct performance measures of interpersonal and neurocognitive skills and one third-party report on real-life performance of interpersonal skills; we also want to look at whether discrepancies appear between the two types of measurements in the two groups of participants. A total of 68 Spanish children between the ages of 7 and 12 years participated; 34 were children with ASD, and 34 showed typical development. All participants were tested for recognition of emotions, solving interpersonal conflicts, and executive function. Significant differences between the two groups were not found on most of the direct performance measures, but they did appear in the report by third parties, in favor of the group with typical development. There was also a significant association between neurocognitive and social variables in the latter group. There were intergroup differences and discrepancies between the direct performance and indirect measures in children with ASD, and these must be explained. For this reason, future studies could seek to explain the cause of these discrepancies with a greater number of measures for each of the skills.

    The underlying neural determinants of general intelligence have been studied intensively, and seem to derive from the anatomical and functional characteristics of a frontoparietal network. Little is known, however, about the underlying neural correlates of domain-specific cognitive abilities, the other factors hypothesized to explain individual performance on intelligence tests. Previous preliminary studies have suggested that spatially distinct neural structures do not support domain-specific cognitive abilities. To test whether differences between abilities that affect performance on verbal and performance tasks derive instead from the morphological features of a single anatomical network, we assessed in two independent samples of healthy human participants (N=83 and N=58; age range, 5-57 years) the correlation of cortical thickness with the magnitude of the verbal intelligence quotient (VIQ)-performance intelligence quotient (PIQ) discrepancy. We operationalized the VIQ-PIQ discrepancy by regressing VIQ onto PIQ (VIQ-regressed-on-PIQ score), and by regressing PIQ onto VIQ (PIQ-regressed-on-VIQ score). In both samples, a progressively thinner cortical mantle in anterior and posterior regions bilaterally was associated with progressively greater (more positive) VIQ-regressed-on-PIQ scores. A progressively thicker cortical mantle in anterior and posterior regions bilaterally was associated with progressively greater (more positive) PIQ-regressed-on-VIQ scores. Variation in cortical thickness in these regions accounted for a large portion of the overall variance in magnitude of the VIQ-PIQ discrepancy. The degree of hemispheric asymmetry in cortical thickness accounted for a much smaller but statistically significant portion of variance in VIQ-PIQ discrepancy.

    Recently, a device called MammoSite, consisting of a balloon and a catheter, was developed to perform partial-breast irradiation using a high-dose-rate (HDR) brachytherapy unit with ease and reproducibility. However, the actual dose to the skin does not agree well with the calculated dose by the treatment planning system because of the difference between the calculation condition and the real treatment condition (i.e., homogeneous water and full scatter condition vs contrast solution and lack of full scatter condition). In this study, the authors experimentally estimated dose discrepancies due to contrast and lack of full scatter in breast HDR brachytherapy with MammoSite. Using metal-oxide-semiconductor field-effect transistor detectors and a breast phantom, the dose discrepancies between the calculation and the treatment conditions were measured according to contrast concentration (10% and 20% volume ratios), balloon size (35 and 60 cm 3 ), and source to detector distance ranging from 25 to 50 mm. The source was an Ir-192 isotope from Nucletron HDR unit. The dose discrepancies from the calculation condition due to both contrast and lack of full scatter combined ranged from about -1.4±2.5% to -18.2±2.0% in the studied cases (error bound is in two sided confidence interval of 80% based on Student's t distribution). In all cases, the effect of lack of full scatter was dominant to that of contrast and significant dose discrepancies existed between the calculation and the real treatment conditions, indicating that the actual skin dose is less than that which is currently calculated.

    The majority of studies on parent-child discrepancies in the assessment of adolescent emotional and behavioral problems have been conducted in Western countries. It is believed that parent-adolescent agreement would be higher in societies with a strong culture of familism. We examined whether parent-adolescent discrepancies in the rating of adolescent emotional and behavioral problems are related to parental and family factors in Taiwan. Participants included 1,421 child-parent pairs of 7th-grade students from 12 middle schools in Northern Taiwan and their parents. We calculated Pearson's correlation coefficients to assess the relationship between parental (Child Behavior Checklist, CBCL) and adolescent (Youth Self Report, YSR) report of emotional/behavioral problem syndromes. Regression models were used to assess parent-adolescent differences in relation to parental psychopathology and family factors. We found that parent-adolescent agreement was moderate (r = 0.37). Adolescents reported higher symptom scores than their parents (Mean Total Problem Score: CBCL: 20.79, YSR: 33.14). Parental psychopathology was related to higher parental ratings and better informant agreement. Parents with higher socioeconomic status (SES) tended to report lower scores for adolescent problem syndromes, resulting in higher levels of disagreement. Greater maternal care was related to higher parent-adolescent agreement. Based on our study findings, we conclude that familism values do not seem to improve parent-child agreement in the assessment of adolescent problem syndromes. The finding that higher SES was related to increased discrepancies speaks to the need to explore the culture-specific mechanisms giving rise to informant discrepancies.

    This study shows the capabilities of a benchmarking system to identify inconsistencies in emission inventories, and to evaluate the reason behind discrepancies as a mean to improve both bottom-up and downscaled emission inventories. Fine scale bottom-up emission inventories for seven urban areas in Norway are compared with three regional emission inventories, EC4MACS, TNO_MACC-II and TNO_MACC-III, downscaled to the same areas. The comparison shows discrepancies in nitrogen oxides (NOx) and particulate matter (PM2.5 and PM10) when evaluating both total and sectorial emissions. The three regional emission inventories underestimate NOx and PM10 traffic emissions by approximately 20-80% and 50-90%, respectively. The main reasons for the underestimation of PM10 emissions from traffic in the regional inventories are related to non-exhaust emissions due to resuspension, which are included in the bottom-up emission inventories but are missing in the official national emissions, and therefore in the downscaled regional inventories. The benchmarking indicates that the most probable reason behind the underestimation of NOx traffic emissions by the regional inventories is the activity data. The fine scale NOx traffic emissions from bottom-up inventories are based on the actual traffic volume at the road link and are much higher than the NOx emissions downscaled from national estimates based on fuel sales and based on population for the urban areas. We have identified important discrepancies in PM2.5 emissions from wood burning for residential heating among all the inventories. These discrepancies are associated with the assumptions made for the allocation of emissions. In the EC4MACs inventory, such assumptions imply high underestimation of PM2.5 emissions from the residential combustion sector in urban areas, which ranges from 40 to 90% compared with the bottom-up inventories. The study shows that in three of the seven Norwegian cities there is need for further improvement of

    Extreme discrepancies in abilities are more common among the most and least able students than among average ability children. Therefore, procedures for identifying gifted children that deliberately or inadvertently rely on a composite score that averages across ability domains will exclude many children who reason exceptionally well in particular symbol systems.

    We report inelastic electron tunneling spectroscopy (IETS) of multilayer molecular junctions with and without incorporated metal nano-particles. The incorporation of metal nanoparticles into our devices leads to enhanced IET intensity and a modified line-shape for some vibrational modes. The enhancement and line-shape modification are both the result of a low lying hybrid metal nanoparticle-molecule electronic level. These observations explain the apparent discrepancy between earlier IETS mea...

    Full Text Available Introduction: Tooth size, occlusal traits, and ethnicity are closely interrelated, and their impact on desirable orthodontic treatment outcome cannot be underestimated. This study was undertaken to assess the occlusal characteristics and ethnic variations in occlusion of Malaysian orthodontic patients and evaluate their correlation with Bolton's tooth size discrepancy. Materials and Methods: On 112 pretreatment study models of orthodontic patients, molar relationship, overjet, overbite, spacing, crowding, midline shift, and Bolton's ratios were assessed. ANOVA, one-sample t-test, Chi-squared test, and Spearman's rho correlation coefficient were used for statistical analysis. Results: Significant difference between anterior ratio of our study and Bolton's ideal values was found, for the entire study sample and Chinese ethnic group. Differences between races and malocclusion groups were not statistically significant (P > 0.05. Significant correlations were found as follows – in Angle's Class I malocclusion between 1 anterior ratio and overbite, 2 overall ratio and maxillary crowding and spacing; in Angle's Class II malocclusion between 1 anterior ratio and overjet and midline shift, 2 overall ratio and mandibular crowding; in Angle's Class III malocclusion between 1 anterior ratio and mandibular crowding and both maxillary and mandibular spacing 2 overall ratio and mandibular crowding. Conclusions: Significant differences in anterior ratio and Bolton's ideal values for the Malaysian population were found, indicating variations in anterior tooth size as compared to Caucasians. Statistically significant correlations existed between Bolton's ratios and occlusal traits. These findings can be applied clinically in diagnosis and treatment planning by keeping in mind the specific discrepancies that can occur in certain malocclusions and addressing them accordingly.

    We investigated the prevalence and correlates of discrepancies between self-reported sleep quality (Pittsburgh Sleep Quality Index) and objective sleep efficiency (actigraphy) in older adults with mild cognitive impairment (MCI) and subsyndromal depression. This was a secondary analysis of a clincial trial with 59 adults aged 60 years and older with MCI and subsyndromal depression. We included baseline data on participants' subjective sleep quality, objective sleep efficiency, depressive symptoms, insomnia diagnosis, and cognitive functioning. Pittsburgh Sleep Quality Index subjective sleep quality and actigraphy-measured sleep efficiency were not significantly correlated ( r = -.06; P = .64), with 61% of participants having subjective-objective sleep discrepancies. Correlates of subjective-objective sleep discrepancy included the presence of an insomnia diagnosis and impaired memory, particularly delayed memory. These findings are important because subjective underestimation of symptoms in older adults with memory impairments may result in sleep disturbances going unrecognized in clinical practice; on the other hand, an insomnia disorder may be a possible remediable contribution to subjective overestimation of sleep disturbances.

    This study evaluated the associations between relationship distress, depression symptoms, and discrepancy in interpersonal perception within couples. After completing a series of discussion tasks, couples (N = 88) rated their behavior using the circumplex-based Structural Analysis of Social Behavior Model (SASB; Benjamin, 1979, 1987, 2000). Overall, couple members were strikingly similar in their interpersonal perceptions, and tended to see themselves as friendly, reciprocal in their focus, and balanced between connection and separateness. As hypothesized, however, perceptual discrepancy was related to relationship distress and depression. Relationship distress was associated with discrepancy regarding transitive behavior focused on the partner, while depression was associated with disagreement about intransitive, self-focused behavior. Analysis of affiliation and autonomy revealed that relationship distress was associated with seeing oneself as reacting with more hostility than the partner sees, and perceiving one's partner as more hostile, more controlling, and less submissive than he or she does. Partners of depressed individuals viewed themselves as more controlling than their mate did. Men's depression was associated with disagreement between partners regarding men's self-focused behavior. Results underscore the importance of considering interpersonal perception when conceptualizing relationship distress and depression within intimate relationships. © 2015 Family Process Institute.

    2012-01-01

    Active and nonlinear microrheology experiments involve a colloidal probe that is forced to move within a material, with the goal of recovering the nonlinear rheological response properties of the material. Various mechanisms cause discrepancies between the nonlinear rheology measured microrheologically and macroscopically, including direct probe-bath collisions, the Lagrangian unsteadiness experienced by the material elements, and the spatially inhomogeneous and rheologically mixed strain field set up around the probe. Here, we perform computational nonlinear microrheology experiments, in which a colloidal probe translates through a dilute suspension of Brownian ellipsoids, whose results we compare against analogous computational experiments on the macroscopic shear rheology of the same model material. The quantitative impact of each of the mechanisms for micro-macro-discrepancy can thus be computed directly, with additional computational experiments performed where the processes in question are ‘turned off’. We show that all three discrepancy mechanisms impact the microrheological measurement quantitatively, and that none can be neglected. This motivates a search for microrheological probes whose geometry or forcing is optimized to minimize these impacts, which we present in a companion article.

    Full Text Available INTRODUCTION: Technological advances in Dentistry have emerged primarily in the area of diagnostic tools. One example is the 3D scanner, which can transform plaster models into three-dimensional digital models. OBJECTIVE: This study aimed to assess the reliability of tooth size-arch length discrepancy analysis measurements performed on three-dimensional digital models, and compare these measurements with those obtained from plaster models. MATERIAL AND METHODS: To this end, plaster models of lower dental arches and their corresponding three-dimensional digital models acquired with a 3Shape R700T scanner were used. All of them had lower permanent dentition. Four different tooth size-arch length discrepancy calculations were performed on each model, two of which by manual methods using calipers and brass wire, and two by digital methods using linear measurements and parabolas. RESULTS: Data were statistically assessed using Friedman test and no statistically significant differences were found between the two methods (P > 0.05, except for values found by the linear digital method which revealed a slight, non-significant statistical difference. CONCLUSIONS: Based on the results, it is reasonable to assert that any of these resources used by orthodontists to clinically assess tooth size-arch length discrepancy can be considered reliable.

    Investigators over years have been fascinated by dermatoglyphic patterns which has led to the development of dermatoglyphics as a science with numerous applications in various fields other than being the best and most widely used method for personal identification. To assess the correlation between dermatoglyphic patterns and sagittal skeletal discrepancies. A total of 180 patients, aged 18-40 years, were selected from those who attended the outpatient clinic of the Deparment of Orthodontics and Dentofacial Orthopedics, Mar Baselios Dental College, Kothamangalam, Kerala, India. The fingerprints of both hands were taken by ink and stamp method after proper hand washing. The patterns of arches, loops and whorls in fingerprints were assessed. The total ridge count was also evaluated. Data was also sent to the fingerprint experts for expert evaluation. The sagittal jaw relation was determined from the patient's lateral cephalogram. The collected data was then statistically analyzed using Chi-square tests, ANOVA and Post-hoc tests and a Multinomial regression prediction was also done. A significant association was observed between the dermatoglyphic pattern exhibited by eight fingers and the sagittal skeletal discrepancies (pdermatoglyphic patterns and sagittal skeletal discrepancies. Dermatoglyphics could serve as a cost effective screening tool of these craniofacial problems.

    The present research sought to provide the initial development, validation and reliability for a measure (WEIGHTCOPE) to assess the variation in how women, who are currently trying to lose or maintain weight, cope with common, perceived weight-related discrepancies. To this end, two studies were conducted to 1) develop an initial list of coping responses to common weight-related triggers, 2) create an initial measurement model through exploratory factor analysis (study 1; n = 470), and 3) provide initial validation for the measure through confirmatory factor analysis (study 2; n = 310). Results support the initial validity and reliability of a 38-item, 10-factor structure: Physical Activity, Healthy Eating, Suppressed Eating, Supplement Use, Self-Regulation, Positive Reframing, Social Support, Disengagement, Camouflage, and Comfort Food. The present findings reiterate individual variation in coping choice in response to a perceived weight-related discrepancy, and its prospective assessment with the WEIGHTCOPE. The WEIGHTCOPE can be an integral tool for public health and clinical practice, where triggers are common, and interventions are employed to enhance the use of more positive forms of weight control behaviors and/or avoid negative consequences of weight- and fat-related discrepancies. Future research can use the WEIGHTCOPE to help guide theoretical and pragmatic approaches to various triggering events and potential moderators of coping.

Osteotomy of the tibia, excision of fibrosis, and decortications were carried out. After a latency period of 5 days, the lengthening started at a rate of 1 mm per day.Results: The pseudarthrosis healed and the gained correction was 21.73%. The index consolidation was 49 days/cm. Minor complications were reported.Discussion: Osteomyelitis of long bones is a common poverty-related disease in Africa. The disease usually is diagnosed at an advanced stage with complications. In these conditions, treatment is much more difficult. Most surgical procedures treating this condition use the Ilizarov device. The most common reported surgical complications are refractures and recurrence of infection.Conclusion: This technique should be popularized in countries with limited resources because it would be an attractive alternative to the amputations that are sometimes performed.Keywords: Limb length discrepancy (LLD, bone gap, Ilizarov device

    Background and aims Nowadays centric relation is defined as a musculoskeletal stable position, with the condyles forward, as far upward as possible, centered transversely and with the articular disc properly interposed. On the other hand, centric occlusion or maximum intercuspidation is a dental determined position. The purpose of this pilot study is to evaluate the direction, frequency and magnitude of the discrepancy between centric occlusion and centric relation in all three axial directions, in a muscular non-deprogrammed population, before the beginning of orthodontic treatment. Methods The study group was represented by 40 symptomatic and asymptomatic patients seeking orthodontic treatment in a private dental office in Cluj-Napoca, Romania between 2014 and 2015. All patients had full records and articulator mounted models. All measurements were analyzed three-dimensionally. Results 85% of the patients had vertical and 87.5% had horizontal CO-CR discrepancy for both condyles. 87.5% of the cases have had a significant condylar displacement in at least one of the three planes. Conclusions We should be aware of the dental occlusion determined by the dental contacts and the occlusion dictated by the musculoskeletal stable position of the condyles. The bigger the discrepancy between these two positions at the level of the condyles, the greater the chances to have either a patient who will develop a form of TMD before/during or after the orthodontic or prosthetic treatment, or a patient suffering already, but poorly diagnosed.

    The paper describes the design and testing of a photogrammetric measurement protocol set up to determine the discrepancies between the planned and actual position of computer-guided template-based dental implants. Two moulds with the implants positioned in pre- and post- intervention are produced and separately imaged with a highly redundant block of convergent images; the model with the implants is positioned on a steel frame with control points and with suitable targets attached. The theoretical accuracy of the system is better than 20 micrometers and 0.3-0.4° respectively for positions of implants and directions of implant axes. In order to compare positions and angles between the planned and actual position of an implant, coordinates and axes directions are brought to a common reference system with a Helmert transformation. A procedure for comparison of positions and directions to identify out-of-tolerance discrepancies is presented; a numerical simulation study shows the effectiveness of the procedure in identifying the implants with significant discrepancies between pre- and post- intervention.

For secondary outcomes, 2% were upgraded to primary, 12.5% were omitted and 30.9% were newly introduced in the publication. Overall, 45.4% of reviews had at least one discrepancy when compared to the protocol; these were reported in 14.5% reviews. The number of review updates appears to be associated with discrepancies between final review and protocol (OR: 3.18, 95% CI: 1.77, 5.74, p<0.001. The risk of reporting significant results was lower for both downgraded outcomes [RR: 0.52, 95% CI: 0.17, 1.58, p = 0.24] and upgraded or newly introduced outcomes [RR: 0.77, 95% CI: 0.36, 1.64, p = 0.50] compared to outcomes with no discrepancies. The risk of reporting significant results was higher for upgraded or newly introduced outcomes compared to downgraded outcomes (RR = 1.19, 95% CI: 0.65, 2.16, p = 0.57. None of the comparisons reached statistical significance.While no evidence of selective outcome reporting was found in this study, based on the present analysis of SRs published within COHG systematic reviews, discrepancies between outcomes in pre-published protocols and final reviews continue to be common. Solutions such as the use of standardized outcomes to reduce the prevalence of this issue may need to be explored.

    Discrepancies, or perceptual distance, between leaders' self-ratings and followers' ratings of the leader are common but usually go unrecognized. Research on discrepancies is limited, but there is evidence that discrepancies are associated with organizational context. This study examined the association of leader-follower discrepancies in Implementation Leadership Scale (ILS) ratings of mental health clinic leaders and the association of those discrepancies with organizational climate for involvement and performance feedback. Both involvement and performance feedback are important for evidence-based practice (EBP) implementation in mental health. A total of 593 individuals-supervisors (leaders, N=80) and clinical service providers (followers, N=513)-completed surveys that included ratings of implementation leadership and organizational climate. Polynomial regression and response surface analyses were conducted to examine the associations of discrepancies in leader-follower ILS ratings with organizational involvement climate and performance feedback climate, aspects of climate likely to support EBP implementation. Both involvement climate and performance feedback climate were highest where leaders rated themselves low on the ILS and their followers rated those leaders high on the ILS ("humble leaders"). Teams with "humble leaders" showed more positive organizational climate for involvement and for performance feedback, contextual factors important during EBP implementation and sustainment. Discrepancy in leader and follower ratings of implementation leadership should be a consideration in understanding and improving leadership and organizational climate for mental health services and for EBP implementation and sustainment in mental health and other allied health settings.

    Full Text Available Objectives: To evaluate the impact of a pharmacy-technician centered medication reconciliation (PTMR program by identifying and quantifying medication discrepancies and outcomes of pharmacist medication reconciliation recommendations. Methods: A retrospective chart review was performed on two-hundred patients admitted to the internal medicine teaching services at Cooper University Hospital in Camden, NJ. Patients were selected using a stratified systematic sample approach and were included if they received a pharmacy technician medication history and a pharmacist medication reconciliation at any point during their hospital admission. Pharmacist identified medication discrepancies were analyzed using descriptive statistics, bivariate analyses. Potential risk factors were identified using multivariate analyses, such as logistic regression and CART. The priority level of significance was set at 0.05. Results: Three-hundred and sixty-five medication discrepancies were identified out of the 200 included patients. The four most common discrepancies were omission (64.7%, non-formulary omission (16.2%, dose discrepancy (10.1%, and frequency discrepancy (4.1%. Twenty-two percent of pharmacist recommendations were implemented by the prescriber within 72 hours. Conclusion: A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

    To investigate the influence of cardiovascular risk factors, including fasting plasma glucose (FPG), on the association between electrocardiographic (ECG) and echocardiographic left ventricular hypertrophy (LVH) in an elderly population. We tested cross-sectional associations between electrocardiographic and echocardiographic LVH, defining LVH according to the Sokolow-Lyon voltage combination, Cornell voltage-duration product, or left ventricular mass index (LVMI). Differences between standardized LVMI and Sokolow-Lyon voltage combination or Cornell voltage-duration product (absolute value/cut-off value for LVH) were used as outcome variables in order to identify explanatory variables associated with diagnostic discrepancies between ECG and echocardiography. Of the 1382 subjects included, 77% did not display any signs of LVH, 6% had LVH defined by ECG only, 13% had LVH defined by echocardiography only, and 5% had LVH on both ECG and echocardiography. Older subjects and those with higher blood pressure and RWT were more likely to have a relatively greater LVMI on echocardiography than that predicted on ECG (odds ratio: 1.65 per 10 years (95% confidence interval (CI): 1.27-2.15), p = .0002, odds ratio: 1.17 per 10 mmHg (95% CI: 1.09-1.25), p < .0001, and odds ratio: 1.21 per 0.10 (95% CI: 1.02-1.42), p = .03). In addition, discrepancy was also seen in females and subjects receiving antihypertensive medication (odds ratio: 1.41 (95% CI: 1.04-1.89), p = .03 and odds ratio: 1.41 (95% CI: 1.06-1.87), p = .02), but FPG did not independently influence discrepancy between ECG and echocardiography. Age, blood pressure, female sex, greater RWT and use of antihypertensive medication were associated with a greater risk of non-consistency between LVH determined by ECG and echocardiography.

    Background: Sonographic size of suspicious thyroid lesions is an essential parameter in the evaluation of thyroid nodules, determining the need for needle biopsy and has impact on the extent of surgery. Limited data is available on the correlation between the size of the thyroid nodule on sonography and the actual size measured during histological examination. The aim of the present study was to compare these two modalities and to discuss the potential clinical implications of the findings in the study population. Methods: The database of Rabin Medical Center was reviewed for all patients with histologically proven papillary carcinoma of the thyroid treated by thyroid surgery between 2005 and 2010. Results: 292 patients with papillary thyroid carcinoma were included. The mean sonographic size of the nodule was 2.19 ± 1.15 cm. The mean pathological diameter was 1.69 ± 1.09 cm. Discrepancies between tumor histological diameter and the sonographically measurement were more prominent in tumors larger than 1.5 cm. Nonetheless, 18.8% of thyroid nodules that were measured by US as larger than 1 cm, were found to be smaller than 1 cm on final pathology. Similarly, 7.2% of nodules evaluated by sonography were determined as being larger than 4 cm, while their definitive size was smaller than 4 cm. Conclusions: We noted a significant discrepancy between the preoperative sonographic and the pathologic size measurements for papillary thyroid carcinoma. The sonographic evaluation misclassifies both patients with small and large thyroid tumors, and consequently exposes them to unnecessary workup and more extensive operation. This discrepancy between the ultrasound findings and actual tumor size should be taken into account in clinical practice and help guide the evaluation and treatment of patients with thyroid nodules.

    In Japan and elsewhere, ABO genotyping is frequently used in forensic practice for identification of a decomposed body. However, the phenotype deduced from the genotyping data is occasionally inconsistent with the real phenotype. In this paper, we report a simple ABO genotyping method in which five single nucleotide polymorphism at nps 220, 261, 796, 802, and 803 are analyzed simultaneously to avoid discrepancies between genetic and serological determinations in ABO*A204, *O303, *O207, *cis-AB01 and *cis-AB02 alleles. This method can be used for the genotyping of badly decomposed remains or old bloodstains.

    Introduction Anisomelia is a condition of leg length discrepancy. It is often treated with epiphysiodesis of the growth plate to inhibit growth. Epiphysiodesis has become the most commonly used procedure for leg length equalization. Current techniques involve opening cortical windows, usage...... ablation sites (lateral and medial) identified at the proximal tibia growth plate using x-ray. Under general anesthesia, a probe was inserted and the ablation performed. T1, T2 and water content MR images were performed right after the procedure, 12 weeks later for 6 animals, and 6 months later...

    Full Text Available Background and Aim: An important criterion for success assessment of implant-supported prostheses is marginal fit. Vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. Despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. The aim of this study was to evaluate the marginal gap and overhang in three casting methods with two different alloys in ITI implants.Materials and Methods: In this experimental in vitro study 48 analog abutments were randomly divided into six groups as follows: 1 burn out cap + BegoStar, 2 impression cap + BegoStar, 3 conventional wax up + BegoStar, 4 burn out cap + Verabond2, 5 impression cap + Verabond2, 6 conventional wax up + Verabond2. Waxing was done in 0.7 mm thickness verified by a digital gauge and a putty index was made for all groups. Reamer was used for correction of the finish line after casting in all groups. Castings were seated on analog abutments and embedded in acrylic resin. Specimens were sectioned by isomet instrument and polished and cleaned by ultrasonic cleaner for 10 min. The marginal gap and overextended margins of castings were examined under a  Scanning Electron Microscope (SEM (X200. The mean gap and margin overextension were calculated for each group. Data were analyzed by multivariate analysis and Bonferroni post-hoc test with p<0.05 as the level of significance.Results: No significant difference in gap size was observed among the three casting methods with two alloys (P=0.056. The marginal gap was not different in the studied casting methods (P=0.092. Gold alloy crowns showed lower marginal gaps compared to base metal alloy crowns (P<0.001. No significant difference in overhang size was observed among casting methods with two alloys (P=0.093. Base metal alloy crowns showed less overhang compared to gold alloy crowns (P<0.001.

    We report inelastic electron tunneling spectroscopy (IETS) of multilayer molecular junctions with and without incorporated metal nanoparticles. The incorporation of metal nanoparticles into our devices leads to enhanced IET intensity and a modified line shape for some vibrational modes. The enhancement and line-shape modification are both the result of a low lying hybrid metal nanoparticle-molecule electronic level. These observations explain the apparent discrepancy between earlier IETS measurements of alkane thiolate junctions by Kushmerick et al. [Nano Lett. 4, 639 (2004)] and Wang et al. [Nano Lett. 4, 643 (2004)].

    Body image (BI) is a multidimensional construct that includes perceptual, attitudinal, behavioural components, and feedback from other people's perception of oneself. The feedback from others and the degree to which one accepts or rejects it can determine self evaluation and perception. Body weight perception is a strong determinant of nutritional habits and weight management among adolescents. One of the barriers to reducing rise in obesity prevalence could be its cultural acceptability in some developing countries. To explore the gender influences on perception of self- and opposite-sex body images (BI), perceived body weight and the actual body weight categories at which discrepancies occur among the perceived BIs in undergraduates. This was a survey of perceptual dimension of BI, perceived body weight and actual body weight carried out in 121 undergraduates aged 21-29 years. Discrepancies occurred between self-perceived BI and each of actual body weight (p= 0.00 at 0.00-0.02 confidence interval (CI)), perceived body weight (p= 0.01 at 0.000-0.02 CI) and self-ideal BI (p= 0.03 at 0.000-0.05 CI) of normal-weight males. Self-perceived BI and perceived body weight also differed in normal-weight females (p= 0.02 at 0.000-0.04 CI). Discrepancies (p= 0.02 at 0.00-0.04 CI) occurred between self-perceived BI and self-ideal BI, and between self-perceived BI and desired BI (p= 0.02 at 0.00-0.04 CI) in overweight females. Gender differences occurred for self-ideal BI (p= 0.00 at 0.00-0.02 CI), ideal image for the opposite sex (IBIOS) (p= 0.02 at 0.00-0.04 CI) and desired BI (p= 0.00 at 0.00-0.02 CI). Normal-weight males perceived their BI differently from their actual body weight, perceived body weight and self-ideal BI whereas normal-weight females perceived their BI differently from only their perceived body weight. Discrepancies occur between self-ideal BI and self-perceived BI, and between self-perceived BI and desired BI in overweight females. There are differential

    Chance, Lauren J; Costigan, Catherine L; Leadbeater, Bonnie J

    2013-12-01

    For immigrant families, differential acculturation between mothers and fathers may present challenges to parenting adolescents. The current study investigated the concurrent relations among discrepancies in parental acculturation, discrepancies in parental expectations for adolescents, and coparenting quality with a sample of 162 married immigrant Chinese Canadian couples with adolescents (mean age = 14.94 years; SD = 1.73). Acculturation was assessed as parents' behavioral involvement in both Canadian and Chinese cultures. As predicted, mother-father differences in acculturation (in relation to both cultures) were related to discrepant expectations for how much adolescents should assist the family. Further, mother-father differences in Chinese acculturation were related to fathers' perceptions of a poorer coparenting relationship. Finally, this relation was partially mediated by discrepant parental expectations for adolescent assistance. Implications for parenting roles, enculturation, family dynamics, and intervention are considered.

  20. The influence of discrepancies between adolescent and parent ratings of family dynamics on the well-being of adolescents.

    Science.gov (United States)

    Stuart, Jaimee; Jose, Paul E

    2012-12-01

    The present study examined whether discrepancies between adolescent and parent ratings of family dynamics predict adolescent well-being over time. Self-report data from 972 adolescent-parent dyads collected at two time points separated by one year were analyzed. Both adolescents and parents rated a variety of family dynamics (e.g., cohesion), and adolescents reported on their levels of well-being (confidence, purpose in life, and positive relations with others). Significant discrepancies between adolescents' and parents' perceptions of family functioning were found for all positive family dynamics, but not for family conflict. Furthermore, discrepancies increased over time and larger discrepancies were noted for older adolescents. Results from the residualized path model showed that discrepancies were bidirectionally related to adolescent well-being. In addition, age was found to moderate the predictive model. Specifically, 14-15 year olds (year 10) were found to be more stable in their well-being over time than younger adolescents. Also, results indicate that well-being is a significantly stronger negative predictor of discrepancies over time for the 14-15 year olds (year 10) than the for 10-11 year olds (year 6). The authors suggest that future research would benefit from investigations of the relationship between divergent perspectives of family members and adjustment outcomes of adolescents.

  1. Relationship between parenting stress and informant discrepancies on symptoms of ADHD/ODD and internalizing behaviors in preschool children.

    Directory of Open Access Journals (Sweden)

    Yu-Chi Chen

    Full Text Available Parent and teacher ratings of child behaviors are often discrepant, and these discrepancies may be correlated with parenting stress. The present study explored whether various parenting stress factors are associated with discrepancies between parent and teacher ratings of attention-deficit/hyperactivity disorder and oppositional defiant disorder (ODD as well as internalizing symptoms in preschool children. We recruited 299 Taiwanese preschool children (aged 4-6 years from the community or via clinical referrals. A structural equation modeling was used to analyze the relationships among three factors derived from the Parenting Stress Index-Short Form and informant discrepancies on symptoms of inattention, hyperactivity/impulsivity, ODD, and internalizing behaviors. Scores reported by parents were higher for each of the symptoms examined than those reported by teachers, and the degree of agreement between informants ranged from low to moderate. The parental distress factor of parenting stress was associated only with parent ratings, whereas other factors of parenting stress-parent-child dysfunctional interaction and parents' stress resulted from their child's temperament-were correlated with both parent and teacher ratings. Only parental distress factor predicted informant discrepancies for all behavioral symptoms assessed. Our findings suggest that parental distress should be considered when parent rating scores show significant discrepancies from that of teacher rating scores.

    This study examined the impact of sexual closeness on sexual well-being. We developed a nuanced and multifaceted conceptualization of sexual closeness in the form of a constellation of ideal sexual closeness with a partner, actual sexual closeness, and the discrepancy between the two. Data were obtained from a diverse sample of N = 619 participants who took part in the Lives and Relationships Study: A longitudinal survey of men and women in relationships living in the U.S. and Canada. Increases in sexual closeness discrepancies over a period of 1 year predicted concomitant decreases in two indicators of sexual well-being: sexual satisfaction and orgasm frequency evaluations. Decreases in sexual closeness discrepancies resulted in improvement in sexual well-being. Individuals who reported no sexual closeness discrepancies and experienced no changes in sexual closeness discrepancies tended to have the highest levels of sexual well-being. Importantly, sexual closeness discrepancies were robust predictors of sexual well-being, above and beyond individuals' actual sexual closeness, general relationship closeness, and other demographic and relationship characteristics known to be associated with sexual well-being. The present findings demonstrate that how close people feel sexually to their relationship partners is part of a general constellation of factors related to relationship closeness that, only when considered together, sufficiently explain the ways in which experiences of closeness impact sexual well-being in romantic relationships.

  3. Degree and Direction of Sexual Desire Discrepancy are Linked to Sexual and Relationship Satisfaction in Couples Transitioning to Parenthood.

    Many new parents are concerned that they have different levels of interest in sex than their partner. Understanding the role of desire discrepancies in their sexual and relationship satisfaction could help promote adjustment. In community couples, larger desire discrepancies have been inconsistently linked to lower sexual and relationship satisfaction. However, these studies rarely accounted for both the degree and direction (e.g., which partner has higher desire) of the discrepancy. We surveyed 255 mixed-sex new parent couples to assess their sexual desire, sexual satisfaction, and relationship satisfaction. Using polynomial regression with response surface analysis (RSA), we found that desire discrepancies between partners (i.e., when partners were more mismatched as opposed to matched on their levels of sexual desire) were associated with lower sexual (but not relationship) satisfaction for both partners. However, the direction of desire discrepancy mattered: Parents felt less satisfied when mothers were the higher-desire partner compared to when fathers were the higher-desire partner. In addition, when partners' level of sexual desire was in agreement, they were more sexually and relationally satisfied if both partners reported higher compared to lower desire. Results demonstrate the important role of both the magnitude and direction of desire discrepancies in new parent couples.

    The objective of this work was to examine the relation between patterns of substance use among newly married couples and marital satisfaction over time. In particular, this work examined if differences between husbands' and wives' heavy alcohol use and cigarette smoking, rather than simply use per se, predicted decreases in marital satisfaction over the first 7 years of marriage. Married couples (n = 634 couples) were assessed on a variety of substance use and relationship variables at the time of marriage and again at the first, second, fourth and seventh years of marriage. After controlling for key socio-demographic variables, discrepancies in husband and wife cigarette smoking and heavy alcohol use were related to significant reductions in marital satisfaction. Importantly, couples who were discrepant on both substances experienced the greatest declines in marital satisfaction over time. Patterns of substance use among newly married couples are important predictors of changes in marital functioning over time. It was not simply the heavy alcohol use or cigarette smoking that predicted dissatisfaction but, rather, differences between husbands' and wives' substance use that impacted the relationship.

  5. Explaining discrepancies in arrest rates between Black and White male juveniles.

    2009-10-01

    The authors investigated discrepancies in arrest rates between Black and White male juveniles by examining the role of early risk factors for arrest. Two hypotheses were evaluated: (a) Disproportionate minority arrest is due to increased exposure to early risk factors, and (b) a differential sensitivity to early risk factors contributes to disproportionate minority arrest. The study included 481 Black and White boys who were followed from childhood to early adulthood. A higher incidence of early risk factors accounted for racial differences related to any juvenile arrest, as well as differences in violence- and theft-related arrests. However, increased exposure to early risk factors did not explain race differences in drug-related arrests. Minimal support was found for the hypothesis that a differential sensitivity to risk factors accounts for disproportionate rate of minority male arrests. In sum, most racial discrepancies in juvenile male arrests were accounted for by an increased exposure to childhood risk factors. Specifically, Black boys were more likely to display early conduct problems and low academic achievement and experience poor parent-child communication, peer delinquency, and neighborhood problems, which increased their risk for juvenile arrest.

  6. Impedance computations and beam-based measurements: A problem of discrepancy

    Science.gov (United States)

    Smaluk, Victor

    2018-04-01

    High intensity of particle beams is crucial for high-performance operation of modern electron-positron storage rings, both colliders and light sources. The beam intensity is limited by the interaction of the beam with self-induced electromagnetic fields (wake fields) proportional to the vacuum chamber impedance. For a new accelerator project, the total broadband impedance is computed by element-wise wake-field simulations using computer codes. For a machine in operation, the impedance can be measured experimentally using beam-based techniques. In this article, a comparative analysis of impedance computations and beam-based measurements is presented for 15 electron-positron storage rings. The measured data and the predictions based on the computed impedance budgets show a significant discrepancy. Three possible reasons for the discrepancy are discussed: interference of the wake fields excited by a beam in adjacent components of the vacuum chamber, effect of computation mesh size, and effect of insufficient bandwidth of the computed impedance.

    The herniated nucleus pulposus (HNP) is a major cause of low back pain and sciatica. High resolution computed tomography is the most accurate diagnostic tool to define a HNP, because it provides a complete in vivo analysis of bony framework of lumbar spine as well as the supporting soft tissue structures and neural elements. But the discrepancy between neurologic findings and CT findings is often confusing. From May 1983 to August 1986, sixty patients with HNP who had both CT and surgical intervention at Pusan National University Hospital were analyzed. The feasibility of the neurologic examination on HNP and the effect of HNP on nerve root were evaluated on the basis of CT findings. The results were as follows : 1. Thirty-four cases (56.7%) of clinical impression were matched to CT findings in determining level of HNP and affected nerve root. 2. In evaluation of affected level, there was high trend to cause discrepancy between neurologic findings and CT findings in multiple disc involvement than in single involvement. 3. There was no correlation between degree of nerve root compression determined by CT and pattern of neurologic signs (motor weakness, sensory deficit, and reflex change)

    To have the capability for long-term prediction of stratospheric ozone (O3), chemistry-climate models have often been tested against observations on decadal time scales. A model-observation discrepancy in the tropical O3 response to the 11-year solar cycle, first noted in 1993, persists for more than 20 years: While standard photochemical models predict a single-peak response in the stratosphere, satellite observations show an unexpected double-peak structure. Various studies have explored uncertainties in photochemistry and dynamics but there has not been compelling evidence of model biases. Here we suggest that decadal satellite orbital drifts relative to the diurnal cycle could be the primary cause of the discrepancy. We show that the double-peak structure can be reproduced by adding the AM/PM diurnal difference to the single-peak response predicted by the standard photochemistry. This work illustrates the importance of a synergistic and iterative process involving observations and theory in search of robust climate signals.

    Both the FRAX and Garvan calculators are used to estimate absolute risk of fracture, but they sometimes produce different estimates. We sought to determine which patient characteristics contribute to these discrepancies. Ten-year hip fracture risk was estimated for 122 women, using both FRAX and Garvan with bone mineral density (BMD). Differences in estimates of hip fracture were assessed, both in absolute terms and with respect to a treatment threshold of 3%. Garvan estimates were higher than FRAX estimates across the range of ages and BMDs studied. A history of falls or of multiple fractures increased risk calculated by Garvan 3-6-fold, but did not account for all differences between calculators. Discrepancies around a 3% treatment threshold occurred in 31/122 (25%). Women aged 70-74 years, and women with osteopenia were most likely to have discordant estimates. Most discordant estimates (29/31) had a Garvan estimate ≥ 3% and FRAX calculator, use of the other calculator should be considered to help guide treatment decisions.

    Folate assays by use of radiolabeled folate provide obvious practical advantages over the standard microbiological assay, but remain incompletely tested. We therefore compared results for 415 sera with a kit involving 3 H-labeled folate and the Lactobacillus casei microbiological method. We examined the patients' data when there were discrepancies between the two methods. Although the correlation overall was satisfactory, results were discrepant in 25% of cases. In 74% of the latter, the radioassay result appeared to be the correct one, primarily because L. casei results were suppressed by antibiotics being taken by the patient. The radioassay occasionally gave falsely high values for patients with liver disease and falsely low ones for patients who had received isotopes for scanning purposes. Several assay kits that make use of 125 I- or 75 Se-labeled folate were also tested. Although these results correlated with the results of 3 H-labeled folate assay, various problems appeared, including the possible need for serum-supernate control tubes in one kit. Answers to these and other questions and careful clinical correlation of results are needed for any folate radioassays before their adoption for routine clinical use

    Full Text Available http://dx.doi.org/10.5007/1980-0037.2008v10n2p189 After a brief review of the literature on the effects of creatine supplementation on high-intensity intermittent exercise performance, the main aim of this study was to discuss methodological differences between studies which could explain the discrepancies observed in the literature. The effects of creatine supplementation on high-intensity intermittent exercise performance have been investigated in depth. Although the results of much research demonstrates the effi cacy of this supplement, there is just as much evidence that does not support this ergogenic effect. The explanation for this divergence appears to be multifactorial, although it is always linked to methodological characteristics. Study design (crossover or parallel groups, individual variability of muscular creatine content, chronic high meat intake, sample size, exercise protocol characteristics (body weight dependence and time between series, and gender and age all differ between studies and are potentially the variables responsible, to differing extents, for the discrepancies observed in the literature. Studies involving young males, with parallel group design, adequate statistical power, control of the incorporation of creatine into muscles, food intake assessment and intermittent exercise protocols in which performance is independent of body weight and with rest-recovery intervals of 1 to 6 minutes, usually produce positive results. The many methodological factors which can contribute to divergence on the ergogenic effects of creatine should be considered in futures studies, as well as when prescribing creatine supplementation.

    In daily life, people make decisions not only for themselves but also on behalf of others. There may be differences in terms of the endowment effect when making decisions in these two situations. In Study 1, this question was investigated with an existing dataset exploring the traditional endowment effect, in which 86 students (M age = 20.8 years, SD = 5.0) at Harvard University were asked to make a decision on selling or buying a coffee mug for themselves or for others as brokers. When making decisions for the self, the average price demanded by sellers was much higher than that offered by buyers; while making decisions for others, the price discrepancy disappeared. In Study 2, a similar study was conducted with a sample of 42 Chinese university students (M age = 22.3 years, SD = 2.5), and a similar pattern of results was obtained. Further analysis indicated that when making decisions for others, only buyers increased their valuations, therefore mitigating the seller-buyer price discrepancy. Finally, the findings were interpreted from the perspective of Construal Level Theory. © The Author(s) 2016.

    Full Text Available Abstract Background Ideally, the distribution of research funding for different types of cancer should be equitable with respect to the societal burden each type of cancer imposes. These burdens can be estimated in a variety of ways; “Years of Life Lost” (YLL measures the severity of death in regard to the age it occurs, "Disability-Adjusted Life-Years" (DALY estimates the effects of non-lethal disabilities incurred by disease and economic metrics focus on the losses to tax revenue, productivity or direct medical expenses. We compared research funding from the National Cancer Institute (NCI to a variety of burden metrics for the most common types of cancer to identify mismatches between spending and societal burden. Methods Research funding levels were obtained from the NCI website and information for societal health and economic burdens were collected from government databases and published reports. We calculated the funding levels per unit burden for a wide range of different cancers and burden metrics and compared these values to identify discrepancies. Results Our analysis reveals a considerable mismatch between funding levels and burden. Some cancers are funded at levels far higher than their relative burden suggests (breast cancer, prostate cancer, and leukemia while other cancers appear underfunded (bladder, esophageal, liver, oral, pancreatic, stomach, and uterine cancers. Conclusions These discrepancies indicate that an improved method of health care research funding allocation should be investigated to better match funding levels to societal burden.

    The purpose of this study was to categorize surgery-related medical terminologies used in South and North Korea and to compare and analyze discrepancies observed in the terms. This study collected medical terminology used in the North Korean medical book "Surgery" and compared it to medical terminology found in the medical glossary of South Korea. The order of the subtitle was described according to the Instruction to Authors. In total, there were 2,168 individual medical terms, of which only 1,004 words (46.3%) were identical to South Korean medical terms. There were 581 similar terms (26.8%), 265 different terms (12.2%), and 318 terms that are nonexistent in South Korea (14.7%). Less than half of the medical terms used in North Korea match those used in South Korea. It is expected that the prolongation of the current division of South and North Korea will only worsen this discrepancy. Further efforts to bridge the gap through academic exchange between South Korea and North Korea are required in preparation for an era of reunification.

    Cemented crowns are increasingly being used on dental implants instead of on screw-retained prostheses because of the reliability of internal Morse taper implant-abutment connections. However, there is a lack of information on the fit of metal ceramic and premachined alumina infrastructures. Therefore, the aim of this study was to evaluate the marginal and internal fits of different metal and alumina infrastructures cemented on universal post abutments. A total of 45 abutments (6 mm in height and 3.3 mm in diameter) were divided into five groups on the basis of their infrastructure material: cobalt-chromium (CoCr), nickel-chromium (NiCr), nickel-chromium-molybdenum-titanium (NiCrMoTi), gold (Au), and premachined alumina. The alumina group showed marginal overextension, and the Au group showed the highest discrepancy in marginal fit among the metal alloys. The CoCr and alumina groups showed the lowest discrepancies in internal fit. In conclusion, the alumina cylinders exhibited the best internal fit, despite their horizontal overextension. Among the metal alloys, CoCr exhibited the best fit at critical regions, such as the cervical and occlusal areas. © 2015 Eur J Oral Sci.

  17. Ensuring survival.

    The global population growth rate has been 1.7% since 1975, while for developing countries it is 2.1%. UN projections are for population to grow from 5.5 billion in 1992 to 10 billion by 2050. Sustainable development is only possible when population growth is balanced with available resources. UN medium population projections of 7.8 billion by 2050 can be reached with 187 million more couples practicing family planning (FP) by the year 2000. Within the past 20 years, 1 billion people, mostly from developed countries, have enjoyed economic growth, but have contributed polluting technologies, excessive waste, and environmentally dangerous economic practices. The generations to come will be affected by the continuance of these practices by the 1 billion affluent population. The bottom billion are mired in poverty and high population growth and survival, needs that hinder their country's economic development, upset fragile ecosystems, and destroy the balance between human beings and the environment. International migration on a large scale could be the by-product of population growth. Progress has been made since the 1974 UN Conference on Population in Bucharest. There are still, however, vulnerable populations, the poorest households, the landless and small-holder families, urban squatters and slum dwellers, those living in low lying deltas and along coasts, and women. Women control family resources and their micro environment. Sustainable development is not possible without the elimination of prejudice against women. Reproductive freedom for women must be a priority. High quality, readily available FP services are also needed for those desiring this. The difficulty is in providing FP services that conform to a woman's social and cultural background and personal needs; success is dependent on involving women in the process and holding men more responsible for FP. Development means allowing for the legitimate aspirations of the majority not just the specialized concerns of the destitute. The environmental cost of development must be reduced and there must be a more equitable distribution of benefits. Borders do not confine problems and governments must work together. 1 billion of the global budget of 4.5 billion dollars is contributed by developed countries, and that amount needs to be increased by 50%. Population aid should be 4% not 2% of all assistance.

    Aim: To evaluate the discrepancy rate among specialist registrars (SPR) to assess whether seniority had a bearing on the discrepancy rate. To investigate which were the commonly missed abnormalities and the consequences for teaching purposes. To investigate the role of a specialist consultant neuroradiologist in reporting paediatric head computed tomography examinations. Materials and methods: The study was carried out over a 9-month period at the regional paediatric hospital during which time 270 CT head examinations were reported. Reporting in the department is carried out by one of the five general paediatric radiologists (GR) and also a specialist paediatric neuroradiologist (NR). The NR was considered the reference standard, who corroborated in areas of discrepancy with a second senior NR for this study. Of the 270 examinations, 260 were reported by the paediatric NR, 160 were reported by the SPR, GR, and NR, and 51 were reported by an SPR and the NR. In addition, four were reported by the GR and the NR, 45 by the NR only, seven by the GR only, and three cases were reported by the GR and an SPR. The discrepancy rates were calculated for GR versus NR, and SPR versus NR. All the discrepancies were re-evaluated by a second senior NR and confirmed in all cases. The reports of the SPR were further scrutinized. The trainees of training years 1-3 were considered junior and 4-5 were considered senior. Results: There was a discrepancy in 26/164 cases (15.9%) reported by the GR and NR. There was a discrepancy in 59/211 cases (28%) reported by an SPR and NR. The chi-squared test (two-sided) showed a significant difference (p = 0.005) between the two groups. There was a discrepancy in 36/118 cases (30.5%) reported by the junior SPR and NR. There was a discrepancy in 23/93 cases (24.7%) reported by a senior SPR and NR. The chi-squared test (two-sided) showed a non-significant difference (p = 0.353) between the two groups. Conclusion: The performance of the SPR was

    Full Text Available Bridging the gap between the predictions of coarse-scale climate models and the fine-scale climatic reality of species is a key issue of climate change biology research. While it is now well known that most organisms do not experience the climatic conditions recorded at weather stations, there is little information on the discrepancies between microclimates and global interpolated temperatures used in species distribution models, and their consequences for organisms' performance. To address this issue, we examined the fine-scale spatiotemporal heterogeneity in air, crop canopy and soil temperatures of agricultural landscapes in the Ecuadorian Andes and compared them to predictions of global interpolated climatic grids. Temperature time-series were measured in air, canopy and soil for 108 localities at three altitudes and analysed using Fourier transform. Discrepancies between local temperatures vs. global interpolated grids and their implications for pest performance were then mapped and analysed using GIS statistical toolbox. Our results showed that global interpolated predictions over-estimate by 77.5 ± 10% and under-estimate by 82.1 ± 12% local minimum and maximum air temperatures recorded in the studied grid. Additional modifications of local air temperatures were due to the thermal buffering of plant canopies (from -2.7 °K during daytime to 1.3 °K during night-time and soils (from -4.9 °K during daytime to 6.7 °K during night-time with a significant effect of crop phenology on the buffer effect. This discrepancies between interpolated and local temperatures strongly affected predictions of the performance of an ectothermic crop pest as interpolated temperatures predicted pest growth rates 2.3-4.3 times lower than those predicted by local temperatures. This study provides quantitative information on the limitation of coarse-scale climate data to capture the reality of the climatic environment experienced by living organisms. In highly

    Gestational age is estimated by ultrasound using fetal size as a proxy for age, although variance in early growth affects reliability. The aim of this study was to identify characteristics associated with discrepancies between last menstrual period-based (EDD-LMP) and ultrasound-based (EDD-US) estimated delivery dates. We identified all singleton births (n = 1 201 679) recorded in the Swedish Medical Birth Register in 1995-2010, to assess the association between maternal/fetal characteristics and large negative and large positive discrepancies (EDD-LMP earlier than EDD-US and 10th percentile in the discrepancy distribution vs. EDD-LMP later than EDD-US and 90th percentile). Analyses were adjusted for age, parity, height, body mass index, smoking, and employment status. Women with a body mass index >40 kg/m 2 had the highest odds for large negative discrepancies (-9 to -20 days) [odds ratio (OR) 2.16, 95% CI 2.01-2.33]. Other factors associated with large negative discrepancies were: diabetes, young maternal age, multiparity, body mass index between 30 and 39.9 kg/m 2 or +1 SD), and unemployment. Several maternal and fetal characteristics were associated with discrepancies between dating methods. Systematic associations of discrepancies with maternal height, fetal sex, and partly obesity, may reflect an influence on the precision of the ultrasound estimate due to variance in early growth. © 2016 The Authors.

    Preoperative histology is a major component in the perioperative selective lymph node (LN) dissection decision process. Discrepancy between preoperative endometrial sampling and final specimen histopathology is generally accepted. The goals of this project are to determine if discrepancy of histopathology is associated with alteration of adjuvant treatment or outcome. We performed a retrospective cross-sectional analysis of all patients undergoing surgery for endometrial cancer at a single institution from 2010 to 2014. All patients had preoperative endometrial sampling. Histopathology discrepancy was evaluated for potential in variation of perioperative LN dissection. Criteria for not performing LN dissection was defined as preoperative endometrioid histology, grade 1 or 2 lesion, myometrial invasion of 50% or less, and primary tumor diameter 2 cm or less. A total of 352 patients were identified; 44 were excluded because of no preoperative pathology or no residual disease on final pathology. Discrepancy of histopathology was noted in 64/308 (20.8%; 95% confidence interval [CI], 16.2%-25.3%) patients. Preoperative endometrioid histology was noted in 272 patients, and 17/272 (6.3%; 95% CI, 3.4%-9.1%) had preoperative sampling reviewed as a grade 1 or 2 endometrioid lesion and final specimen was upgraded to grade 3. Downstaging occurred in 3/272 (1.1%; 95% CI, 0%-2.3%) patients with preoperative grade 3 lesion and final specimen demonstrated grade 1 or 2 disease. All 3 patients' primary tumor diameter was greater than 2 cm and therefore received LN dissection. Histopathological discrepancy that would alter perioperative LN dissection decision based on the aforementioned criteria occurred in 2/272 (0.7%; 95% CI, 0%-1.8%). Despite a 20% discrepancy of preoperative and postoperative histopathology, discrepancy that would alter a perioperative decision for LN dissection occurs in only 0.7% of cases in this retrospective single-institutional experience.

    We investigated 1) the impact of differences in intelligence quotient discrepancy (IQD) on motor skills of preschool-aged children with autism spectrum disorders (ASD); 2) the relationships between IQD and motor skills in preschool-aged children with ASD. A total of 127 ASD preschool-aged children were divided into three groups according to the size of the IQD: IQD within 1 standard deviation (1SD; EVENIQ; n=81), discrepantly higher verbal intelligence quotient (VIQ; n=22; VIQ>performance intelligence quotient [PIQ] above 1SD [≥15 points]), and discrepantly higher PIQ (n=24; PIQ>VIQ above 1SD [≥15 points]). Children's IQD and motor skills were determined with the Wechsler Preschool and Primary Scale of Intelligence™ - Fourth Edition and the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT), respectively. One-way analysis of variance revealed significant group differences for the fine motor domain of the CDIIT and the visual-motor coordination subtest ( F =3.37-4.38, p <0.05). Children with discrepantly higher PIQ were associated with better fine motor skills than were children with even IQD and those with discrepantly higher VIQ, and vice versa. IQD (PIQ - VIQ) had significant positive correlations with the fine motor domain and fine motor subtests of the CDIIT ( r =0.18-0.29, p <0.05). The IQD can identify different levels of fine motor skills in preschool-aged children with ASD. This study suggests important implications for clinicians, therapists, and researchers: discrepantly higher PIQ could be related to better visual-motor coordination, and discrepantly higher VIQ could be related to poor visual-motor coordination. Furthermore, the results support that when therapists are working with preschool-aged children with ASD who are developing fine motor skills or undertaking fine motor tasks related to visual-motor coordination, they may need to pay attention to the children's IQD.

    Women are twice as likely as men to develop major depressive disorder (MDD) and, while the neurobiological factors underlying this discrepancy are yet to be identified, estrogen almost certainly plays a role. MDD can be precipitated or exacerbated by exposure to stress and there is substantial evidence to suggest that estrogen can interact with stress systems to produce unique stress effects in females. This review integrates current research in animal models regarding estrogen-stress interactions in three areas of the brain known to be relevant to MDD: the hippocampus, the amygdala and the prefrontal cortex. The results from these studies are discussed in the context of MDD, and their implications for future treatment of MDD in women are explored.

    2006-01-01

    This study examined how female undergraduate students anticipated they would approach a friend or family member with disordered eating and what kinds of support they believed to be helpful. The relationship between eating disorder symptomatology and anticipated approaches also was examined. Participants read vignettes depicting scenarios involving a friend or family member with disordered eating and described their anticipated approach. They also rated the helpfulness of various support attempts, and completed the EDI-2. Although collaborative approaches were rated more favorably than controlling approaches, 76% of responses generated by participants fell into the latter category. Reasons for the discrepancy between support attempts offered and those that are believed to be most helpful and the implications of these findings to the treatment and prevention of eating disorders are addressed.

    We revisit the `two-component virial theorem' (2VT) in the light of recent theoretical and observational results related to the `dark matter problem'. This modification of the virial theorem offers a physically meaningful framework to investigate possible dynamical couplings between the baryonic and dark matter components of extragalactic systems. In particular, we examine the predictions of the 2VT with respect to the `acceleration-discrepancy relation' (ADR). Considering the combined data (composed of systems supported by rotation and by velocity dispersion), we find the following: (i) The overall behaviour of the 2VT is consistent with the ADR. (ii) The 2VT predicts a nearly constant behaviour in the lower acceleration regime, as suggested in recent data on dwarf spheroidals. We also briefly comment on possible differentiations between the 2VT and some modified gravity theories.

    SYNOPSIS Objective This study examines relations between adolescents’ and their mothers’ perceptions of the family and adolescent anxiety symptomatology. Design Surveys were administered to 145 15- to 18-year-old adolescents and their mothers. Results Adolescents viewed the family more negatively than did their mothers. In addition, adolescent girls’ perceptions of the family (satisfaction and communication) negatively predicted later adolescent anxiety symptomatology. Significant interactions between adolescent and mother reports of family satisfaction and communication also were found for girls, but not for boys. For girls, discrepant family perceptions with their mothers appeared to protect them from anxiety if their mothers had negative perceptions of the family. Conclusions Understanding the similarities and differences among family members’ perspectives yields useful predictive information that cannot be obtained from studying these perspectives in isolation from one another.

    Using a diamond-anvil cell (DAC) phase transformation and equation of state (EOS) at room temperature for some lanthanides and actinides were studied to multimegabar (megabar = 100 GPa) pressures. Experimental data are compared with the theoretically predicted crystal structural changes and the pressure-volume relationships. A generalized trend for the phase transformations in the lanthanides can be seen, which has broad agreement with theory. There is a general agreement between theory and experiment for the structural changes in the lighter actinides, however in detail there are some discrepancies still. We conclude that an accurate and robust theoretical base for predicting the phase transformations in the f-electron metals can be developed by incorporating the DAC data as markers for fine tuning the theory.

    The purpose of the present study was to examine whether the association between explicit self-esteem and relationship outcomes was moderated by implicit self-esteem. This was accomplished by asking 210 undergraduates who were currently involved in romantic relationships to complete measures of their explicit self-esteem, implicit self-esteem, mate retention strategies, and likelihood of future infidelity. Implicit self-esteem was found to moderate the association between high explicit self-esteem and relationship outcomes for male participants such that men with discrepant high self-esteem (i.e., high explicit self-esteem but low implicit self-esteem) reported less use of mate retention strategies and perceived a greater likelihood of future infidelity in their relationships during the next year. These findings provide additional support for the idea that fragile self-esteem may have consequences for the manner in which individuals perceive their relationships.

    Social support can buffer against stressors often associated with having family members with autism spectrum disorder. This study included 112 parents and typically developing siblings of children with autism spectrum disorder. Relations between self-reported typically developing sibling emotional and behavioral problems and discrepancy between social support frequency and importance were examined via polynomial regression with response surface analysis. Typically developing siblings who described social support as frequent and important reported relatively few problems. Typically developing siblings who reported social support as highly important but infrequent exhibited the highest emotional and behavioral difficulties. Thus, typically developing siblings with little support who view support as highly important may be particularly responsive to social support improvement efforts.

    Full Text Available Abstract The family is one of the most important socializing agents in adolescent sex education. However, multiple barriers to communication within families have been identified. Therefore, this study aimed to characterize and understand the processes by which parents and their adolescent children communicate about sexuality. Two questionnaires were completed by 711 fathers/mothers and 566 male/female students in 21 schools in Cali (Colombia, and 15 discussion groups were formed. The results showed that conversations about sexuality focused on protection for women and on sexuality promotion for men. Furthermore, it was found that greater fluency exists in father/son and mother/daughter conversations. The largest discrepancy between parents and teenagers was the adults' belief that it is sufficient to mention certain topics in a directive manner and the children's expectations that parents will discuss the value and dynamics of the sexual experience. Embarrassment and lack of communication tools hinder communication processes.

    We present spatially and velocity-resolved echelle spectroscopy for NGC 7009 obtained with the UVES spectrograph at the European Southern Observatory's Very Large Telescope. Our objective is to analyze the kinematics of emission lines excited by recombination and collisions with electrons to determine whether similarities or differences could be useful in elucidating the well-known abundance discrepancy derived from them. We construct position-velocity maps for recombination, fluorescence, charge transfer, and collisionally excited lines. We find a plasma component emitting in the C II, N II, O II, and Ne II recombination lines whose kinematics are discrepant: they are incompatible with the ionization structure derived from all other evidence and the kinematics derived from all of these lines are unexpectedly very similar. We find direct evidence for a recombination contribution to [N II] {lambda}5755. Once taken into account, the electron temperatures from [N II], [O III], and [Ne III] agree at a given position and velocity. The electron densities derived from [O II] and [Ar IV] are consistent with direct imaging and the distribution of hydrogen emission. The kinematics of the C II, N II, O II, and Ne II lines does not coincide with the kinematics of the [O III] and [Ne III] forbidden emission, indicating that there is an additional plasma component to the recombination emission that arises from a different volume from that giving rise to the forbidden emission from the parent ions within NGC 7009. Thus, the chemical abundances derived from either type of line are correct only for the plasma component from which they arise. Apart from [N II] {lambda}5755, we find no anomaly with the forbidden lines usually used to determine chemical abundances in ionized nebulae, so the abundances derived from them should be reliable for the medium from which they arise.

  13. Resolving the discrepancy in the mass determination from the gravitational redshift of Sirius B

    White dwarfs (WDs) are the remnants of stars with initial masses less than 8Msol. Many studies make use of WDs as tools to help in other areas of astronomy, for example, to determine the ages of stellar populations. The white dwarf mass-radius relation is a foundation of many studies which are only possible because the WD mass-radius relation allows us to calculate these parameters when they cannot be independently observed.Despite its well accepted theoretical basis, the white dwarf mass-radius relation has been difficult to test observationally due to the difficulty of making observations of sufficient precision. We propose STIS observations of Sirius B, which is the nearest WD, to obtain the spectrum of the H alpha absorption line which can be used to measure the mass of the WD through the gravitational redshift method. Previous HST observations of Sirius B have allowed us to measure the mass to a high level of precision. However this has uncovered a significant unexplained discrepancy between the mass calculated using the gravitational redshift method and the astrometrically determined mass. Our aim is to resolve this discrepancy by using the traditional method of measuring the gravitational red shift of the WD relative to the luminous primary, in this case Sirius A. We will measure the wavelengths of the H-alpha lines in both Sirius B and A using the same STIS G750M grating during the same visit. This will remove many of the systematic uncertainties affecting previous observations. This will either allow us to confirm the validity of this fundamental method and the mass-radius relationship, or it may uncover a gap in our understanding which needs to be addressed.

Interobserver reproducibility of 2D-SWE was evaluated, and the relationship between interobserver difference in LS and related factors was analyzed using linear regression analyses. We considered age, sex, alanine transaminase, cholesterol, body mass index (BMI, and waist circumference as clinical factors, and the mean value of standard deviation (SDM, its difference between two examiners, mean diameter of the regions of interest (ROIM, and its difference in the elasticity map as investigation factors. The cut-off value for significant factors to predict interobserver discrepancies in LS-based fibrosis stage was also inspected.In total, 176 patients were enrolled. The intraclass correlation coefficient between the two examiners was 0.784. In the univariate analysis, SDM and ROIM were independently associated with interobserver differences in LS as well as BMI, waist circumference, and the difference of ROI, but SDM and ROIM were the only ones significantly related in multivariate analysis (p<0.001 and p = 0.021, respectively. The best cut-off value for SDM in predicting interobserver discrepancy in LS-based fibrosis stage was 1.4.Interobserver reproducibility of 2D-SWE for measuring LS was good and SDM was the most significantly associated factor with interobserver differences in LS and interobserver discordance in LS-based fibrosis stage.

    Inconsistent global/basin ocean heat content (OHC) changes were found in different ocean subsurface temperature analyses, especially in recent studies related to the slowdown in global surface temperature rise. This finding challenges the reliability of the ocean subsurface temperature analyses and motivates a more comprehensive inter-comparison between the analyses. Here we compare the OHC changes in three ocean analyses (Ishii, EN4 and IAP) to investigate the uncertainty in OHC in four major ocean basins from decadal to multi-decadal scales. First, all products show an increase of OHC since 1970 in each ocean basin revealing a robust warming, although the warming rates are not identical. The geographical patterns, the key modes and the vertical structure of OHC changes are consistent among the three datasets, implying that the main OHC variabilities can be robustly represented. However, large discrepancies are found in the percentage of basinal ocean heating related to the global ocean, with the largest differences in the Pacific and Southern Ocean. Meanwhile, we find a large discrepancy of ocean heat storage in different layers, especially within 300-700 m in the Pacific and Southern Oceans. Furthermore, the near surface analysis of Ishii and IAP are consistent with sea surface temperature (SST) products, but EN4 is found to underestimate the long-term trend. Compared with ocean heat storage derived from the atmospheric budget equation, all products show consistent seasonal cycles of OHC in the upper 1500 m especially during 2008 to 2012. Overall, our analyses further the understanding of the observed OHC variations, and we recommend a careful quantification of errors in the ocean analyses.

    Lonely adolescents report that they have poor social skills, but it is unknown whether this is due to an accurate perception of a social skills deficit, or a biased negative perception. This is an important distinction, as actual social skills deficits require different treatments than biased negative perceptions. In this study, we compared self-reported social skills evaluations with peer-reported social skills and meta-evaluations of social skills (i.e., adolescents' perceptions of how they believe their classmates evaluate them). Based on the social skills view, we expected negative relations between loneliness and these three forms of social skills evaluations. Based on the bias view, we expected lonely adolescents to have more negative self- and meta-evaluations compared to peer-evaluations of social skills. Participants were 1342 adolescents (48.64 % male, M age  = 13.95, SD = .54). All classmates rated each other in a round-robin design to obtain peer-evaluations. Self- and meta-evaluations were obtained using self-reports. Data were analyzed using polynomial regression analyses and response surface modeling. The results indicated that, when self-, peer- and meta-evaluations were similar, a greater sense of loneliness was related to poorer social skills. Loneliness was also related to larger discrepancies between self- and peer-evaluations of loneliness, but not related to the direction of these discrepancies. Thus, for some lonely adolescents, loneliness may be related to an actual social skills deficit, whereas for others a biased negative perception of one's own social skills or a mismatch with the environment may be related to their loneliness. This implies that different mechanisms may underlie loneliness, which has implications for interventions.

    The present study examines discrepancies between self- and adult-perceptions of social competence in children with attention deficit-hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and possible co-morbid disruptive behaviour disorders (DBD). Self-reported questionnaires were collected from multiple informants at the baseline of a multi-systemic family intervention programme for children (aged 5-12) with ADHD, ASD and possible co-morbid DBD. In total, out of the 154 families eligible for the study, information was received concerning children from 124 families (children n = 121; mothers n = 117; fathers n = 86; teachers n = 97). In addition to this, a comparison community sample of 318 school-aged children (approximately 10 years old) was utilized to examine the perceptions of children's social competence across intervention and population groups in more detail. Children's self-perceptions in the prosocial dimension of social competence (i.e. cooperating skills, empathy) did not differ between the intervention and comparison groups. Interestingly, the children in the intervention sample expressed more impulsivity and disruptiveness - the antisocial dimension of social competence - when compared with the children in the comparison sample. Adult ratings demonstrated that mothers, fathers and teachers reported decreased prosocial behaviour and increased antisocial behaviour across overall dimensions and sub-dimensions when compared with adults' ratings of elementary school children. Informant discrepancies between self-ratings and adult ratings across intervention groups yielded significant effect sizes (eta-squared) across all domains of social competence ranging from .09 to .25. Children's positive self-ratings of social competence relative to adult ratings increased within intervention sample when compared with population sample. The intervention sample children appeared to acknowledge their social competence deficits, yet self

    To explore the discrepancy between sleep diary and actigraphic measures of sleep in adolescents and to ascertain whether these discrepancies may vary according to characteristics of the participant. Participants were 385 adolescents aged 13-18years (X=15.6, standard deviation [SD]=0.95; 60% male) from eight high schools in South Australia. Adolescents completed the School Sleep Habits Survey and Pediatric Daytime Sleepiness Scale during class time, followed by an 8-day sleep diary and wrist actigraphy. The Flinders Fatigue Scale was completed on the final day of the study. Parents completed a sleep, medical, education, and family history survey. Actigraphic estimates of wake after sleep onset (WASO) were substantially greater than sleep diary estimates (74min actigraphy vs. 7min sleep diary) and actigraphic estimates of total sleep time were substantially less than sleep diary and parent report (6h 51min actigraphy vs. 8h 16min sleep diary vs. 8h 51 parent report). Actigraphy displayed no significant relationship with daytime functioning and weak relationships with concomitantly recorded sleep diary variables. Sex and puberty-related differences in actigraphic scoring were found, with more WASO and less sleep scored in boys compared to girls and more WASO scored amongst pubertally-mature boys than boys of less advanced pubertal development. There may be differences in the sleep of adolescents that result in less actigraphic total sleep scored than perceived, particularly in boys, possibly because of increased sleep motor activity in adolescents that actigraphic algorithms score as wake. This is a significant concern that requires further examination with polysomnography. Copyright © 2012 Elsevier B.V. All rights reserved.

    The objectives of our study were to describe the vaccination recommendations by general practitioners (GPs) for their patients and practices for their children, and to identify any discrepancies between them. Applying multiple correspondence analysis and agglomerative hierarchical cluster analysis to data from a 2014 cross-sectional survey of a national sample of GPs, we constructed a typology based on the patterns of associations between GPs' vaccine recommendations to their patients and practices to their own children's vaccinations. This study includes the 1038 GPs who reported that they had at least one child aged 2-25 years. Nearly half (47%, 482/1021) reported that all of their children were vaccinated against hepatitis B but that they did not always recommend that vaccine to patients; the same discordance was observed among 36% (369/1027) for the measles-mumps-rubella vaccine, 19% (194/1013) to 28% (290/1019) for routine and catch-up meningococcal C vaccination, and 27% (136/496) for the human papillomavirus vaccine. Cluster analysis showed that 37% (95% CI 33%-39%) of GPs reported an above-average rate of systematic vaccine recommendations for their patients, and most reported that all their children were vaccinated (low level of discordance), whereas 60% (95% CI 58%-64%) had a high level of discordance, that is, most reported that their children were vaccinated, but did not always recommend the same vaccines to their patients. Many GPs do not report the same attitude concerning the vaccination of their children and their patients. The reasons underlying these discrepancies, possibly including vaccine hesitancy, should be investigated. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

    2006-05-01

    Analysis of the discrepancy between memory and intellectual ability has received some support as a means for evaluating memory impairment. Recently, comprehensive base rate tables for General Ability Index (GAI) minus memory discrepancy scores (i.e., GAI-memory) were developed using the WAIS-III/WMS-III standardization sample (Lange, Chelune, & Tulsky, in press). The purpose of this study was to evaluate the clinical utility of GAI-memory discrepancy scores to identify memory impairment in 34 patients with Alzheimer's type dementia (DAT) versus a sample of 34 demographically matched healthy participants. On average, patients with DAT obtained significantly lower scores on all WAIS-III and WMS-III indexes and had larger GAI-memory discrepancy scores. Clinical outcome analyses revealed that GAI-memory scores were useful at identifying memory impairment in patients with DAT versus matched healthy participants. However, GAI-memory discrepancy scores failed to provide unique interpretive information beyond that which is gained from the memory indexes alone. Implications and future research directions are discussed.

    Although more individuals are adopting yoga into their lives, little research has examined practitioners' expectations and experiences of their yoga instructor's behavior. Discrepancies between real and ideal behaviors of yoga instructors may lead to unsatisfactory experiences and decrease the potential impact of yoga practice. This study investigated differences between yoga practitioners' real and ideal perceptions of their yoga teacher's behavior and the relationship between discrepant beliefs and students' symptoms of depression, anxiety,and stress. The Perceptions of Yoga Teacher Questionnaire (PYTQ), a recently developed survey of student attitudes regarding yoga teachers' behavior, was administered ina national online survey of yoga students and teachers. Greater discrepancy between real and idea yoga teacher behavior was anticipated to be positively associated with practitioners' symptoms of depression, anxiety, and stress. Pearson correlations corrected for multiple comparisons revealed that yoga students and teachers are generally satisfied with their teacher's behaviors. Significant discrepancies between real and ideal teacher behavior were found for both groups. Higher discrepancy scores were associated with symptoms of stress and anxiety but not depression for students, but not for teachers. These preliminary findings provide insight into the relationship between expectancies and real yoga teacher behaviors and their links to student emotional adjustment.More research in this area is warranted.

    2014-01-01

    A common perception is that increased on-call workload leads to increased resident mistakes. To test this, we evaluated whether increased imaging volume has led to increased errors by residents. A retrospective review was made of all overnight neuroradiology CT exams with a primary resident read from 2006-2010. All studies were over-read by staff neuroradiologists next morning. As the volume is higher on Friday through Sunday nights, weekend studies were examined separately. Discrepancies were classified as either minor or major. "Major" discrepancy was defined as a discrepancy that the staff radiologist felt was significant enough to potentially affect patient care, necessitating a corrected report and phone contact with the ordering physician and documentation. The total number of major discrepancies was recorded by quarter. In addition, the total number of neuroradiology CT studies read overnight on-call was noted. The mean number of cases per night during the weekday increased from 3.0 in 2006 to 5.2 in 2010 (pneuroradiology exam volumes, there continues to be a low major discrepancy rate for primary resident interpretations. While continued surveillance of on-call volumes is crucial to the educational environment, concern of increased major errors should not be used as sole justification to limit autonomy.

    Purpose We investigated 1) the impact of differences in intelligence quotient discrepancy (IQD) on motor skills of preschool-aged children with autism spectrum disorders (ASD); 2) the relationships between IQD and motor skills in preschool-aged children with ASD. Methods A total of 127 ASD preschool-aged children were divided into three groups according to the size of the IQD: IQD within 1 standard deviation (1SD; EVENIQ; n=81), discrepantly higher verbal intelligence quotient (VIQ; n=22; VIQ>performance intelligence quotient [PIQ] above 1SD [≥15 points]), and discrepantly higher PIQ (n=24; PIQ>VIQ above 1SD [≥15 points]). Children’s IQD and motor skills were determined with the Wechsler Preschool and Primary Scale of Intelligence™ – Fourth Edition and the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT), respectively. Results One-way analysis of variance revealed significant group differences for the fine motor domain of the CDIIT and the visual–motor coordination subtest (F=3.37–4.38, pmotor skills than were children with even IQD and those with discrepantly higher VIQ, and vice versa. IQD (PIQ – VIQ) had significant positive correlations with the fine motor domain and fine motor subtests of the CDIIT (r=0.18–0.29, pmotor skills in preschool-aged children with ASD. This study suggests important implications for clinicians, therapists, and researchers: discrepantly higher PIQ could be related to better visual–motor coordination, and discrepantly higher VIQ could be related to poor visual–motor coordination. Furthermore, the results support that when therapists are working with preschool-aged children with ASD who are developing fine motor skills or undertaking fine motor tasks related to visual–motor coordination, they may need to pay attention to the children’s IQD.

    The fat talk literature is meager in terms of offering theoretical explanations for women's self-disparaging communication. The research presented here sought to establish a relationship between three prominent body image theories - self-discrepancy theory, social comparison theory, and objectification theory - and fat talk by proposing body dissatisfaction as a potential mediating mechanism. Young adult women (N=201) completed an online questionnaire. As predicted, results revealed that body dissatisfaction significantly mediated the relationships between weight discrepancy, upward comparison, body surveillance and fat talk. Effect size estimates indicated that the size of each indirect effect was medium in magnitude. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Effects of creatine supplementation on high-intensity intermittent exercise: discrepancies and methodological appraisals

    Full Text Available After a brief review of the literature on the effects of creatine supplementation on high-intensity intermittent exercise performance, the main aim of this study was to discuss methodological differences between studies which could explain the discrepancies observed in the literature. The effects of creatine supplementation on high-intensity intermittent exercise performance have been investigated in depth. Although the results of much research demonstrates the effi cacy of this supplement, there is just as much evidence that does not support this ergogenic effect. The explanation for this divergence appears to be multifactorial, although it is always linked to methodological characteristics. Study design (crossover or parallel groups, individual variability of muscular creatine content, chronic high meat intake, sample size, exercise protocol characteristics (body weight dependence and time between series, and gender and age all differ between studies and are potentially the variables responsible, to differing extents, for the discrepancies observed in the literature. Studies involving young males, with parallel group design, adequate statistical power, control of the incorporation of creatine into muscles, food intake assessment and intermittent exercise protocols in which performance is independent of body weight and with rest-recovery intervals of 1 to 6 minutes, usually produce positive results. The many methodological factors which can contribute to divergence on the ergogenic effects of creatine should be considered in futures studies, as well as when prescribing creatine supplementation. Resumo Após breve revisão da literatura existente acerca dos efeitos da suplementação de creatina no rendimento em atividades intermitentes de alta intensidade, o objetivo principal dessa revisão foi discutir diferenças metodológicas dos estudos que possam explicar a divergência encontrada na literatura.

    Full Text Available Background: Medication reconciliation is a major component of safe patient care. One of the main problems in the implementation of a medication reconciliation process is the lack of human resources. With limited resources, it is better to target medication reconciliation resources to patients who will derive the most benefit from it. Objective: The primary objective of this study was to determine the frequency and types of medication reconciliation errors identified by pharmacists performing medication reconciliation at admission. Each medication error was rated for its potential to cause patient harm during hospitalization. A secondary objective was to determine risk factors associated with medication reconciliation errors. Methods: This was a prospective, single-center pilot study conducted in the internal medicine and surgical wards of a tertiary care teaching hospital in the Eastern province of Saudi Arabia. A clinical pharmacist took the best possible medication history of patients admitted to medical and surgical services and compared with the medication orders at hospital admission; any identified discrepancies were noted and analyzed for reconciliation errors. Multivariate logistic regression was performed to determine the risk factors related to reconciliation errors. Results: A total of 328 patients (138 in surgical and 198 in medical were included in the study. For the 1419 medications recorded, 1091 discrepancies were discovered out of which 491 (41.6% were reconciliation errors. The errors affected 177 patients (54%. The incidence of reconciliation errors in the medical patient group was 25.1% and 32.0% in the surgical group (p<0.001. In both groups, the most frequent reconciliation error was the omission (43.5% and 51.2%. Lipid-lowering (12.4% and antihypertensive agents were most commonly involved.

    Full Text Available Abstract Background Clinician training deficits and a low and declining autopsy rate adversely impact the quality of death certificates in the United States. Self-report and records data for the general population indicate that proximate mental and physical health of minority suicides was at least as poor as that of white suicides. Methods This cross-sectional mortality study uses data from Multiple Cause-of-Death (MCOD public use files for 1999–2003 to describe and evaluate comorbidity among black, Hispanic, and white suicides. Unintentional injury decedents are the referent for multivariate analyses. Results One or more mentions of comorbid psychopathology are documented on the death certificates of 8% of white male suicides compared to 4% and 3% of black and Hispanic counterparts, respectively. Corresponding female figures are 10%, 8%, and 6%. Racial-ethnic discrepancies in the prevalence of comorbid physical disease are more attenuated. Cross-validation with National Violent Death Reporting System data reveals high relative underenumeration of comorbid depression/mood disorders and high relative overenumeration of schizophrenia on the death certificates of both minorities. In all three racial-ethnic groups, suicide is positively associated with depression/mood disorders [whites: adjusted odds ratio (AOR = 31.9, 95% CI = 29.80–34.13; blacks: AOR = 60.9, 95% CI = 42.80–86.63; Hispanics: AOR = 34.7, 95% CI = 23.36–51.62] and schizophrenia [whites: AOR = 2.4, 95% CI = 2.07–2.86; blacks: AOR = 4.2, 95% CI = 2.73–6.37; Hispanics: AOR = 4.1, 95% CI = 2.01–8.22]. Suicide is positively associated with cancer in whites [AOR = 1.8, 95% CI = 1.69–1.93] and blacks [AOR = 1.8, 95% CI = 1.36–2.48], but not with HIV or alcohol and other substance use disorders in any group under review. Conclusion The multivariate analyses indicate high consistency in predicting suicide-associated comorbidities across racial-ethnic groups using MCOD data

    The purpose of this study was to evaluate the effects of the rapid palatal expansion (RPE) on posture and gait analysis in subjects with maxillary transverse discrepancies. Forty-one patients between 6 and 12 years were divided into 3 groups: 10 control subjects (Cs), 16 patients with unilateral posterior crossbite (CbMono), 15 patients with maxillary transverse discrepancy and no crossbite (Nocb). Every subject underwent gait analysis and posturographic examination in order to evaluate the presence of balance alterations before (T0) and after (T4) RPE application. The examinations were performed through a six-cameras stereophotogrammetric system (60-120Hz, BTS S.p.A.) synchronized with two force plates (FP4060, Bertec Corp.). Romberg test was performed on a force plate, and the statokinesiogram and joint kinematics were evaluated. One-way Anova was performed among the variables after evidence of normal distribution (Levene's test for equality of variances) and Kruskal-Wallis test (P<0.05), in order to compare the three groups of subjects. While paired t-test was performed, or Kruskal-Wallis test, instead when comparing pre- and post-RPE application within the same group of subjects (P<0.05). Tamane T2 or Bonferroni correction was applied where needed. The posturographic analysis reveal significant differences across the 3 population: 95% power frequency in medio-lateral and antero-posterior direction in T0, median frequency in medio-lateral direction in T0, mean power frequency in medio-lateral direction in T0. Significant differences were also registered in the three-dimensional joints kinematics variables, mainly between Cs and Cbmono in T0 and T4 and between Cbmono and Nocb in T4. A detectable correlation between dental occlusion and body posture is shown in this study that confirms another benefit of the RPE. This was mainly revealed in the dynamic posture where modifications at the mandibular level affect the whole body. Copyright © 2018. Published by

    2017-06-01

    It is now well established that motor fluency affects cognitive processes, including memory. In two experiments participants learned a list of words and then performed a recognition task. The original feature of our procedure is that before judging the words they had to perform a fluent gesture (i.e., typing a letter dyad). The dyads comprised letters located on either the right or left side of the keyboard. Participants typed dyads with their right or left index finger; the required movement was either very small (dyad composed of adjacent letters, Experiment 1) or slightly larger (dyad composed of letters separated by one key, experiment 2). The results show that when the gesture was performed in the ipsilateral space the probability of recognizing a word increased (to a lesser extent it is the same with the dominant hand, experiment 2). Moreover, a binary regression logistic highlighted that the probability of recognizing a word was proportional to the speed by which the gesture was performed. These results are discussed in terms of a feeling of familiarity emerging from motor discrepancy.

    School climate has been linked with improved academic achievement and reduced discipline problems, and thus is often a target of school improvement initiatives. However, few studies have examined the extent to which student and teacher perceptions vary as a function of individual, classroom, and school characteristics, or the level of congruence between teachers' and their students' perceptions of school climate. Using data from 1881 fifth-grade students and their 90 homeroom teachers, we examined parallel models of students' and teachers' perceptions of overall school climate and academic emphasis. Two additional models were fit that assessed the congruence between teacher and student perceptions of school climate and academic emphasis. Multilevel analyses indicated that classroom-level factors were more closely associated with teachers' perceptions of climate, whereas school-level factors were more closely associated with the students' perceptions. Further analyses indicated an inverse association between student and teacher ratings of academic emphasis, and no association between student and teacher ratings of overall climate. Teacher ratings were more sensitive to classroom-level factors, such as poor classroom management and proportion of students with disruptive behaviors, whereas student ratings were more influenced by school-level factors such as student mobility, student-teacher relationship, and principal turnover. The discrepancy in ratings of academic emphasis suggests that while all of the respondents may have shared objectively similar experiences, their perceptions of those experiences varied significantly. These results emphasize the importance of assessing both student and teacher perceptions in future research on school climate.

    The current study aimed to (1) offer a large-scale enumeration of college students' lifetime sexual behaviors and sexual behaviors at last event, and (2) apply a gender discrepancy lens to college students' sexual behaviors in order to examine potential gender differences in heterosexual college students' experiences. Nine-hundred and seventy college students between the ages of 18 and 27 from two large universities in the United States participated in the current study. Participants filled out a paper-pencil questionnaire during the last 30 min of class. Measures of lifetime sexual behaviors and engagement in behaviors at last sexual event were replicated from the National Survey of Sexual Health Behavior. Most college students engaged in some form of sexual behavior (manual, oral, vaginal-penile, anal). Men more frequently reported engaging in receptive sexual behaviors (e.g., receiving oral sex) where as women were more likely to engage in performative sexual behaviors (e.g., performing oral sex). At most recent sexual event, men were more likely than women to report being the sexual initiator. Findings highlight gender differences in sexual behavior and provide a foundation for social norms interventions. Holistic sexual health promotion for young adults includes acknowledging and discouraging sites of disparity in equity and pleasure. Therefore, college-level sexual health educators should pay attention to the potential pleasure gap between men and women in heterosexual encounters, and to see pleasure as an important part of sexual health that should be included in social norms campaigns.

    The aim of this study was to evaluate the influence of intramedullary (IM) alignment used in combination with external fixation on the healing index (HI) and lengthening index (LI) in the treatment of congenital and acquired leg length discrepancies (LLD). We compared duration of the external fixator application, LLD, HI and LI between two groups of children: children in Group I underwent limb lengthening by the conventional llizarov technique, and children in Group II underwent a combination of Ilizarov technique and intramedullary alignment with Kirschner wires. Two types of LLDs were treated: congenital and acquired. We found significant differences between the two groups for duration of external fixator application and HI. Significant differences were also noted in the duration of the external fixator application, HI and LI, between patients with congenital and acquired LLDs. We also noted significant differences between Group I and Group II regarding duration of external fixator application for patients with congenital LLD and also regarding HI for both congenital and acquired types of LLD.

    We investigated the implicit preference in terms of food portion in obesity using the affective priming paradigm. Primes representing different portions of fast food (small, medium and large) were used to assess participants' readiness to respond to a positive or negative target word. A self-reported affective rating scale of food portion and a portion judgment task were administered to determine the explicit preference for food portion and portion misperception, respectively. The results of the affective priming paradigm showed an implicit preference for large food portions in the obese group. No implicit preference in terms of food portion was found in the non-obese group. The explicit preference measure of food portion demonstrated a rather negative attitude for large portions in the obese group, whereas the non-obese group reported no explicit preference in terms of food portion. Thus, unlike the non-obese group, the obese group showed clear discrepancies between implicit and explicit preferences in terms of food portion: obese participants demonstrated an implicit, but not an explicit preference for large food portions. These results could not be attributed to a misperception of food portion, as revealed by the portion judgment task. The current findings suggest that social desirability might conceal self-reported preference in terms of food portion and/or that obese individuals are less aware of their internal preferences.

    Determining the differences in the perception of risks between experts who are regularly exposed to radiation, and lay people provides important insights into how potential hazards may be effectively communicated to the public. In the present study we examined lay people's (N = 1020) and experts' (N = 332) perception of five different radiological risks: nuclear waste, medical x-rays, natural radiation, an accident at a nuclear installation in general, and the Fukushima accident in particular. In order to link risk perception with risk communication, media reporting about radiation risks is analysed using quantitative and qualitative content analyses. The results showed that experts perceive radiological risks differently from the general public. Experts' perception of medical X-rays and natural radiation is significantly higher than in general population, while for nuclear waste and an accident at a nuclear installation, experts have lower risk perception than the general population. In-depth research is conducted for a group of workers that received an effective dose higher than 0.5 mSv in the year before the study; for this group we identify predictors of risk perception. The results clearly show that mass media don't use the same language as technical experts in addressing radiological risks. The study demonstrates that the discrepancy in risk perception and the communication gap between the experts and the general population presents a big challenge in understanding each other

    To evaluate the validity (accuracy) and reliability of 2 commonly used clinical methods, 1 indirect (lifts) and 1 direct (tape measure), for assessment of leg length discrepancy (LLD) in comparison to radiograph. Twenty subjects suspected of having LLD participated in this study. Two clinical methods, 1 direct using a tape measure and 1 indirect using lifts, were standardized and carried out by 4 examiners. Difference in height of the femoral heads on standing pelvic radiograph was measured and served as the gold standard. The intraclass correlation coefficient assessing interobserver reliability was 0.737 for lifts and 0.477 for tape measure. The remainder of the analysis is based on the average of the measurements by the 4 examiners. Pearson correlation coefficients were 0.93 for the lifts and 0.75 for the tape measure method. Paired sample t tests showed difference in means of 2 mm (p = 0.051) for lifts and -5 mm (p = 0.007) for tape measure compared with radiograph. Sensitivity and specificity were 55% and 89% for lifts and 45% and 56% for tape measure, respectively, using > 5 mm as the definition for LLD. The wrong leg was identified as being shorter in 1 out of 20 subjects using lifts versus 7 out of 20 using tape measure. The indirect standing method of LLD measurement using lifts had superior validity, interobserver reliability, and specificity in comparison with radiograph over the direct supine method using tape measure. Both clinical methods underestimated LLD compared with radiograph.

    Using a sample of continuously-married individuals (793 women and 847 men) and their spouses drawn from the first two waves of the NSFH, we examine change in individuals' attitudes about mothers' employment. We investigate hypotheses derived from three models of attitude change: the exposure model, the interest-based model, and the control model. We find support for hypotheses derived from all three. Consistent with exposure hypotheses, the adoption of fundamentalist beliefs reduces egalitarianism, while spouses' egalitarianism and spouses' education are positively related to individuals' own egalitarianism. As predicted in both exposure and interest hypotheses, women's entry into employment is positively related to women's egalitarianism, while wives' occupational prestige is positively related to men's egalitarianism. Congruent with the interest model, the presence of a young child is positively associated with women's egalitarianism. Consistent with the exposure model, the number of children in the home reduces men's egalitarianism, and a traditional division of housework decreases women's egalitarianism. Finally, consistent with the gender ideology discrepancy hypothesis, derived from the control model, individuals whose background, work, and family life are inconsistent with their gender ideology at wave 1 shift their gender ideology at wave 2 in a direction that is more compatible with their background, work, and family life: egalitarians with traditional life patterns at wave 1 are more traditional in their gender ideology at wave 2, and traditionals with egalitarian life patterns at wave 1 are more egalitarian at wave 2. We discuss the implications of these patterns for larger scale change in gender ideology.

    Nonadherence to immunosuppressive medication after kidney transplantation is a behavioral issue and as such it is important to understand the psychological factors that influence this behavior. The aim of this study was to investigate the extent to which goal cognitions, illness perceptions, and treatment beliefs were related to changes in self-reported immunosuppressive medication adherence up to 18 months after transplantation. Interviews were conducted with patients in the outpatient clinic 6 weeks (T1; n=113), 6 months (T2; n=106), and 18 months (T3; n=84) after transplantation. Self-reported adherence was measured using the Basel Assessment of Adherence to Immunosuppressive Medications Scale Interview. Psychological concepts were measured using the Brief Illness Perceptions Questionnaire, Beliefs about Medicines Questionnaire, and questions on the importance of adherence as a personal goal, conflict with other goals, and self-efficacy for goal attainment. Nonadherence significantly increased over time to 31% at T3. Perceived necessity of medication, perceived impact of transplant on life (consequences) and emotional response to transplantation significantly decreased over time. Participants who reported low importance of medication adherence as a personal goal were more likely to become nonadherent over time. Illness perceptions can be described as functional and supportive of adherence which is inconsistent with the pervasive and increasing nonadherence observed. There appears therefore to be a discrepancy between beliefs about adherence and actual behavior. Promoting (intrinsic) motivation for adherence goals and exploring the relative importance in comparison to other personal goals is a potential target for interventions.

  11. The discrepancy between food plant preferance and suitability in the moth Dysauxes ancilla

    Full Text Available Growth responses to and preference for different food plants were studied in larvae of the geographically isolated Swedish population of the moth Dysauxes ancilla. Laboratory rearing of D. ancilla larvae showed that, besides a mixed diet, four species from different plant families supported development to the adult moth. There was a significant suitability order among these species according to higher female adult weight and shorter development time; mixed diet and Calluna vulgaris > Hieracium pilosella > Thymus serpyllum > Brachytecium sp. However, these species were not top ranked in preference trials by the larvae. Instead larvae preferred Rumex acetosella, a plant that did not support development to adult moth as a single food source. This discrepancy between larval performance and preference may be explained by advantages from food mixing by the polyphagous larvae; an improved nutrient balance, a possibility of diluting toxic secondary substances and of switching foods to fit changing physiological needs. In Nature other factors such as microclimatic conditions, predators and parasitoids probably also influence the foraging behaviour of D. ancilla larvae.

    retrospective study examined the OR turnaround data of 875 elective surgery cases scheduled at the Marienhospital, Vechta, Germany, between July and October 2014. The frequency distributions of planned and actual OR turnaround times were compared and correlations between turnaround times and various factors were established, including the time of day of the procedure, patient age and the planned duration of the surgery. Results: There was a significant difference between mean planned and actual OR turnaround times (0.32 versus 0.64 hours; P <0.001. In addition, significant correlations were noted between actual OR turnaround times and the time of day of the surgery, patient age, actual duration of the procedure and staffing changes affecting the surgeon or the medical specialty of the surgery (P <0.001 each. The quotient of actual/planned OR turnaround times ranged from 1.733–3.000. Conclusion: Significant discrepancies between planned and actual OR turnaround times were noted during the study period. Such findings may be potentially used in future studies to establish a tool to improve OR planning, measure OR management performance and enable benchmarking.

    Patients with Turner syndrome (TS) frequently show short stature and skeletal deformities, such as kyphosis and scoliosis. However, to the best of our knowledge, limb length discrepancy (LLD) has not yet been reported in patients with TS. The case of a 12-yr-old girl with 45,X/47,XXX mosaic TS showing LLD is herein presented. She was on GH therapy for short stature and was noted to have scoliosis in the standing position at a regular examination; however, the scoliosis became less evident in the supine position, which is indicative of LLD. The length of the left leg was 5.0 cm shorter than that of the right leg when measured. She was referred to orthopedics and underwent right distal femoral and right proximal tibial staple epiphysiodesis to shorten the abnormally long limb at 10 yr 6 mo of age. One year after the operation, the LLD decreased from 5.0 to 1.5 cm. During this period, GH was continued. LLD is a rare complication in TS, but when patients with TS show scoliosis in the standing position, re-evaluation for scoliosis in the supine position should be performed and the lengths of both legs should be measured.

  14. The Hiroshima/Nagasaki Survivor Studies: Discrepancies Between Results and General Perception

    2016-01-01

    The explosion of atom bombs over the cities of Hiroshima and Nagasaki in August 1945 resulted in very high casualties, both immediate and delayed but also left a large number of survivors who had been exposed to radiation, at levels that could be fairly precisely ascertained. Extensive follow-up of a large cohort of survivors (120,000) and of their offspring (77,000) was initiated in 1947 and continues to this day. In essence, survivors having received 1 Gy irradiation (∼1000 mSV) have a significantly elevated rate of cancer (42% increase) but a limited decrease of longevity (∼1 year), while their offspring show no increased frequency of abnormalities and, so far, no detectable elevation of the mutation rate. Current acceptable exposure levels for the general population and for workers in the nuclear industry have largely been derived from these studies, which have been reported in more than 100 publications. Yet the general public, and indeed most scientists, are unaware of these data: it is widely believed that irradiated survivors suffered a very high cancer burden and dramatically shortened life span, and that their progeny were affected by elevated mutation rates and frequent abnormalities. In this article, I summarize the results and discuss possible reasons for this very striking discrepancy between the facts and general beliefs about this situation. PMID:27516613

    According to the CaRFAX model, rumination is one of the key underlying mechanisms of overgeneral autobiographical memory (OGM). The association between rumination and OGM is well established in clinical populations, but this relationship is not robust in nonclinical samples. A series of null findings is reported in the current paper. Additionally we followed up on recent findings suggesting that a state of rumination needs to be active in order to detect a relationship between trait-rumination and OGM. Secondary school students (N= 123) completed questionnaires assessing trait-rumination and depressive symptoms as well as two autobiographical memory tests (AMTs), one before and one after a self-discrepancy induction. This induction should trigger state-rumination, which would subsequently promote the retrieval of general rather than specific memories. Trait-rumination failed to predict increases in OGM. We did find, however, that higher BDI-II scores were positively related to an increase in OGM following the induction. This adds to the growing body of evidence that OGM reactivity might be more important than baseline memory specificity.

    The explosion of atom bombs over the cities of Hiroshima and Nagasaki in August 1945 resulted in very high casualties, both immediate and delayed but also left a large number of survivors who had been exposed to radiation, at levels that could be fairly precisely ascertained. Extensive follow-up of a large cohort of survivors (120,000) and of their offspring (77,000) was initiated in 1947 and continues to this day. In essence, survivors having received 1 Gy irradiation (∼1000 mSV) have a significantly elevated rate of cancer (42% increase) but a limited decrease of longevity (∼1 year), while their offspring show no increased frequency of abnormalities and, so far, no detectable elevation of the mutation rate. Current acceptable exposure levels for the general population and for workers in the nuclear industry have largely been derived from these studies, which have been reported in more than 100 publications. Yet the general public, and indeed most scientists, are unaware of these data: it is widely believed that irradiated survivors suffered a very high cancer burden and dramatically shortened life span, and that their progeny were affected by elevated mutation rates and frequent abnormalities. In this article, I summarize the results and discuss possible reasons for this very striking discrepancy between the facts and general beliefs about this situation.

    The terrestrial carbon and water cycles are intimately linked: the carbon cycle isdriven by photosynthesis, while the water balance is dominated by transpiration,and both fluxes are controlled by plant stomatal conductance. The link betweenthese two cycles can be characterised by the water-use efficiency (WUE, mol C mol-1H2O), the rate at which plants exchange water for carbon. An understanding of thespatial and temporal variability in WUE provides fundamental insights into thebehaviour of the terrestrial biosphere and is essential for prediction of terrestrialcarbon and water budgets under global change. WUE can be estimated usingseveral techniques operating at different scales. Leaf gas exchange indicatesinstantaneous leaf WUE; stable isotope 13C discrimination indicates WUEintegrated over time; and eddy flux indicates whole-ecosystem instantaneous WUE.Here we compare global compilations of data for each of these three techniques. Weuse a model of stomatal conductance to define a measure of WUE (g1, kPa0.5) that iscomparable across datasets, and use this measure to examine whether the threeglobal datasets indicate consistent patterns of variation in WUE. Our comparisonhighlights important discrepancies among the three datasets. These discrepanciesmust be resolved if we are to have confidence in our use of these datasets tounderstand and model the terrestrial biosphere.

    The "double demotivation" hypothesis that pay discrepancies decrease work motivation among both lower and higher paid groups was tested in two experiments. In experiment 1, 70 Australian undergraduates received either $1 or $2 to work on an intrinsically rewarding puzzle, with or without knowledge of what amount other participants were receiving. A comparison of participants with a no-payment control showed that participants exhibited significantly reduced intrinsic motivation (seconds spent interacting with the puzzle during a free-choice period) when they knew that they were being under- or overpaid. In experiment 2, 126 occupationally matched Australian workers receiving wages equal to, lower than, or higher than those of counterparts reported their level of job satisfaction and whether they would stay on the job, change jobs, or retire, if given the financial opportunity. Compared with equitably paid workers, employees who felt they were being under- or overpaid reported lower job satisfaction and greater readiness to change jobs. The results provide experimental support for double demotivation, which is relevant not only to international development cooperation but also to Western enterprise bargaining, merit pay, and minority groups in the multicultural workplace.

    The goal of this study was to investigate the level of agreement between tumor sizes measured on ultrasonography (US) and in pathological specimens of papillary thyroid carcinomas (PTCs) and to identify the US characteristics contributing to discrepancies in these measurements. We retrospectively reviewed the US findings and pathological reports of 490 tumors in 431 patients who underwent surgery for PTC. Agreement was defined as a difference of <20% between the US and pathological tumor size measurements. Tumors were divided by size into groups of 0.5-1 cm, 1-2 cm, 2-3 cm, and ≥3 cm. We compared tumors in which the US and pathological tumor size measurements agreed and those in which they disagreed with regard to the following parameters: taller-than-wide shape, infiltrative margin, echogenicity, microcalcifications, cystic changes in tumors, and the US diagnosis. The rate of agreement between US and the pathological tumor size measurements was 64.1% (314/490). Statistical analysis indicated that the US and pathological measurements significantly differed in tumors <1.0 cm in size (P=0.033), with US significantly overestimating the tumor size by 0.2 cm in such tumors (P<0.001). Cystic changes were significantly more frequent in the tumors where US and pathological tumor size measurements disagreed (P<0.001). Thyroid US may overestimate the size of PTCs, particularly for tumors <1.0 cm in size. This information may be helpful in guiding decision making regarding surgical extent.

    Mate value discrepancy (MVD) between heterosexual partners is an important factor influencing relationship satisfaction which, in turn, has an effect on the quality and the stability of the relationship. Therefore, partners' involvement in mate retention behaviours, such as controlling behaviours, can be related to MVD and our study aims to determine whether such an association exists. In order to do so, we analysed female perception of MVD and their opinion regarding the intensity of controlling behaviours performed by themselves as well as their romantic partners. Female perception of the intensity of controlling behaviours performed by both partners was the highest in couples where a woman assesses her own mate value (MV) as higher than her partner's MV and significantly different than in relationships where male MV exceeded those of the female. Our study also indicates that MVD should be taken into account when analysing sex differences in intensities of mate retention behaviours. Finally, we provide evidence supporting the significance of the relationship length for controlling behaviour intensity. Findings are discussed within an evolutionary perspective.

    There are 4 levels 95NB below the decay energy in the Adopted Levels of the 93 micro 08 evaluation that are not reported in this decay scheme: these are 730 6 (5/2+), 799 5 (3/2), 1011 8 (5/2), and 1088keV. These levels have only been reported in reaction studies and their lemma decay modes are not known the 730 level would be fed fed by and allowed beta decay, so this evaluator suggests it is actually the 724 level and the J* assignment is incorrect. The failure to observe decays to the possible 799 and 1011 levels is surprising since these would be 1st forbidden decays and from beta decay systematics (73Ra10) could have branches of several percent. Therefore, one must rely on the fact that other lemda rays have not been reported to support the completeness of this scheme. If one leaves the values of 65F102 in the data set, it is desirable to use either the RAJEVAL or Normalized Residual method to treat this discrepancy. The RAJEVAL method increase the uncertainty for the 65F102 value from 0.2 to 0.88 and gives the resulting value of 64.032(6) while the Normalized Residual method increase this uncertainty to 0.58 and give a result of 64.032(6). So, the adopted value is the same for each of these three methods. (author)

    Comprehensive diagnosis and treatment planning are essential in a successful orthodontic practice. The purpose of this study is to determine and compare intermaxillary tooth size discrepancy (IMTSD) using traditional digital caliper (DC) measurement on plaster dental models and stereomicroscopic digital dental models (SM). The samples were randomly selected from different states of Pakistan. Total 7168 variables were measured on plaster dental casts (128) and SM digital dental models (128) according to the selection criteria. For IMTSD, the 6 variable measured as for anterior tooth size (maxilla, mandibular), overall tooth size (maxilla, mandibular), Bolton's anterior ratios (BAR), and Bolton's overall ratios (BOR). The independent t-test and ANOVA were used for statistical analyses. Significant sexual disparities in the sum of anterior tooth size and overall tooth size via DC and SM methods. No significant sexual disparities for BAR and BOR. No statistically significant differences were found in BAR and BOR between DC and SM. No significant differences were found on IMTSD ratio among different arch length and arch perimeters groups. Norms were developed based on DC and SM for IMTSD. Sexual disparities were observed in the sum of teeth size. However, no significant differences in BAR and BOR for IMTSD between the two methods.

    In their nuclear tables Audi and Wapstra have pointed out a serious mass discrepancy between their extrapolated values for the mercury isotopes and those from a direct measurement by the Manitoba group. The values deviate by as much as 85 ppb from each other with claimed uncertainties of about 16 and 7 ppb, respectively. In order to decide which values are correct the masses of the 198 Hg and 204 Hg isotopes have been measured in the Stockholm Penning trap mass spectrometer SMILETRAP using 52+ ions. This charge state corresponds to a filled Ni electron configuration for which the electron binding energy can be accurately calculated. The mass values obtained are 197.966 768 44(43) u for 198 Hg and 203.973 494 10(39) u for 204 Hg. These values agree with those measured by the Manitoba group, with a 3 times lower uncertainty. This measurement was made possible through the implementation of a cooling technique of the highly charged mercury ions during charge breeding in the electron beam ion source used for producing the Hg 52+ ions

    A good method for solving the nonlinear Vlasov equation is the semi-Lagrangian algorithm, in which the phase space density is represented by its values on a fixed Cartesian grid with interpolation to off-grid points. At each time step, orbits are followed backward from grid points. Since this method is expensive with phase space dimension D > 2, we seek a more efficient discretization of the density. Taking a cue from the theory of numerical quadrature in high dimensions, we explore the idea of replacing the grid by scattered data sites from a low-discrepancy (quasirandom) sequence. We hope to see a reduction in the required number of sites, especially for D > 2. In our first implementation we follow forward orbits rather than backward, and work only with D = 2. We are able to reduce the number of sites by a factor of 8, at least for a limited time of integration. A much bigger reduction is expected in higher dimensions.

    Full Text Available Introduction: Several studies have attempted to demonstrate that the Thrombolysis in Myocardial Infarction (TIMI risk score has the ability to risk stratify emergency department (ED patients with potential acute coronary syndromes (ACS. Most of the studies we reviewed relied on trained research investigators to determine TIMI risk scores rather than ED providers functioning in their normal work capacity. We assessed whether TIMI risk scores obtained by ED providers in the setting of a busy ED differed from those obtained by trained research investigators. Methods: This was an ED-based prospective observational cohort study comparing TIMI scores obtained by 49 ED providers admitting patients to an ED chest pain unit (CPU to scores generated by a team of trained research investigators. We examined provider type, patient gender, and TIMI elements for their effects on TIMI risk score discrepancy. Results: Of the 501 adult patients enrolled in the study, 29.3% of TIMI risk scores determined by ED providers and trained research investigators were generated using identical TIMI risk score variables. In our low-risk population the majority of TIMI risk score differences were small; however, 12% of TIMI risk scores differed by two or more points. Conclusion: TIMI risk scores determined by ED providers in the setting of a busy ED frequently differ from scores generated by trained research investigators who complete them while not under the same pressure of an ED provider.

    Full Text Available BACKGROUND: Autopsy rates in Western countries consistently decline to an average of <5%, although clinical autopsies represent a reasonable tool for quality control in hospitals, medically and economically. Comparing pre- and postmortal diagnoses, diagnostic discrepancies as uncovered by clinical autopsies supply crucial information on how to improve clinical treatment. The study aimed at analyzing current diagnostic discrepancy rates, investigating their influencing factors and identifying risk profiles of patients that could be affected by a diagnostic discrepancy. METHODS AND FINDINGS: Of all adult autopsy cases of the Charité Institute of Pathology from the years 1988, 1993, 1998, 2003 and 2008, the pre- and postmortal diagnoses and all demographic data were analyzed retrospectively. Based on power analysis, 1,800 cases were randomly selected to perform discrepancy classification (class I-VI according to modified Goldman criteria. The rate of discrepancies in major diagnoses (class I was 10.7% (95% CI: 7.7%-14.7% in 2008 representing a reduction by 15.1%. Subgroup analysis revealed several influencing factors to significantly correlate with the discrepancy rate. Cardiovascular diseases had the highest frequency among class-I-discrepancies. Comparing the 1988-data of East- and West-Berlin, no significant differences were found in diagnostic discrepancies despite an autopsy rate differing by nearly 50%. A risk profile analysis visualized by intuitive heatmaps revealed a significantly high discrepancy rate in patients treated in low or intermediate care units at community hospitals. In this collective, patients with genitourinary/renal or infectious diseases were at particularly high risk. CONCLUSIONS: This is the current largest and most comprehensive study on diagnostic discrepancies worldwide. Our well-powered analysis revealed a significant rate of class-I-discrepancies indicating that autopsies are still of value. The identified risk

    Following from previous research on intensity bias and the accessibility model of emotional self-report, the present study examined the role of emotional exhaustion in explaining the discrepancy in teachers' reports of their trait (habitual) versus state (momentary, "real") emotions. Trait reports (habitual emotions, exhaustion) were assessed via trait questionnaires, and state reports (momentary emotions) were assessed in real time via the experience sampling method by using personal digital assistants (N = 69 high school teachers; 1,089 measures within teachers). In line with our assumptions, multi-level analyses showed that, as compared to the state assessment, teachers reported higher levels of habitual teaching-related emotions of anger, anxiety, shame, boredom, enjoyment, and pride. Additionally, the state-trait discrepancy in self-reports of negative emotions was accounted for by teachers' emotional exhaustion, with high exhaustion levels corresponding with a greater state-trait discrepancy. Exhaustion levels did not moderate the state-trait discrepancy in positive emotions indicating that perceived emotional exhaustion may reflect identity-related cognitions specific to the negative belief system. Implications for research and educational practice are discussed.

    While conventional wisdom suggests that parents and their adolescent offspring will often disagree, the nature of discrepancies in informant reports of parenting behaviors is still unclear. This article suggests testing measurement invariance in an effort to clarify if discrepancies in informant scores reflect true differences in perspectives on the same construct, or if the instrument is simply not measuring the same construct across parents and youth. The study provides an example by examining invariance and discrepancy across child, adolescent, and parent reports on the Alabama Parenting Questionnaire. The sample for this study was 255 youth (51.4 % male) aged 6-17 years (M age  = 12.3 years) and an accompanying parent. A five-factor model of the measure was found to provide approximately equivalent measurement across four participant groups (children under 12 years, adolescents aged 12-18 years, and parents of each group, respectively). Latent mean levels of reported parenting constructs varied greatly across informants. Age moderated the association between reports of two subscales, Parental Involvement and Positive Parenting, such that adolescents were more consistent with parents. The findings highlight the utility of testing measurement invariance across informants prior to evaluating differences in their reports, and demonstrate the benefits of considering invariance in the larger conversation over informant discrepancies.

    The aim of this study was to examine relations among missing and discrepant data on the Eating Disorders Examination Questionnaire (EDE-Q; Fairburn & Beglin, 1994) and individual demographic factors and eating disorder symptoms. Data from 3968 men and women collected in five independent studies were examined. Descriptive statistics were used to detect the quantity of missing and discrepant data, as well as independent samples t-tests and chi-square analyses to examine group differences between participants with and without missing or discrepant data. Results indicated significant differences in data completeness by participant race/ethnicity and severity of eating disorder symptoms. White participants were most likely to provide complete survey responses, and Asian American participants were least likely to provide complete survey responses. Participants with incomplete surveys reported greater eating disorder symptoms and behaviors compared with those with complete surveys. Similarly, those with discrepant responses to behavioral items reported greater eating disorder symptoms and behaviors compared with those with congruent responses. Practical implications and recommendations for reducing and addressing incomplete data on the EDE-Q are discussed. Copyright © 2016. Published by Elsevier Ltd.

  18. Possible origin of the gamma-ray discrepancy in the summation calculations of fission product decay heat

    1999-01-01

    In order to identify the origin of the ubiquitous and long-standing discrepancy seen in the γ-ray component of the FP decay heat in the cooling time range 300-3,000 s, a comprehensive analysis of the differences between the summation calculations and the experiments has been carried out. There may be some missing of the β-strength in the high energy region of the FPs in the mass region A=100-110. Especially, 102 Tc, 104 Tc, 105 Tc and 108 Rh are potentially responsible for the γ-ray discrepancy seen in the three major fissioning nuclides, 235 U, 238 U and 239 Pu, systematically. The β-strength functions are theoretically calculated in order to validate this possibility. It is proved that the chance for finding the additional β-strength required to solve the discrepancy is not so large but still exists, and the exact β-feed from Tc to the highly excited levels in Rb should be identified experimentally. Finally, the impact of the γ-ray discrepancy on the reactor-core decay heat is evaluated quantitatively for the first time. It may introduce 0.5-1% underestimation of the total FP decay heat from 1 to 2,000 s after reactor shutdown, and the underestimation may reach 3% at the maximum when the γ-ray component of the decay heat is separately taken into consideration.

    Background: Inconsistencies between mitotic index (MI) and Ki67 measures have been identified in many breast tumour samples. The aim of this study was to describe the prognosis of hormone receptor-positive (HR+) HER2− tumours having discrepant MI and Ki67. Methods: We included a cohort of breast cancer patients initially treated by surgery between 2001 and 2005 in the Institut Curie. Breast cancer-specific survival (BCSS) and disease-free survival (DFS) were analysed according to three proliferation groups: high MI/high Ki67 (MI=3, Ki67>20%), low MI/low Ki67 (MIKi67⩽20%) and discrepant (high MI/low Ki67 or low MI/high Ki67). Results: Among the 1430 patients, 19.6% had discrepant Ki67 and MI, 11.6% had high markers and 68.8% had low markers. The 5-year BCSS was 95.8%, 95% CI (0.93–0.98) in the discrepant group, 99.3%, 95% CI (0.993–0.999) in the low-proliferation group and 91.8%, 95% CI (0.88–0.96) in the high-proliferation group. In multivariate analysis, the survival of the discrepant group was lower than that of the low-proliferation group: BCSS hazard ratio (HR)=3.01 (1.32–6.84; P=0.008) and DFS HR=2.07, 95% CI (1.31–3.26; P=0.002). Among grade 2 tumours in multivariate analysis, DFS of the discrepant group was lower than that of the low MI/low Ki67 group: HR=1.98, 95% CI (1.14–3.46), P=0.02. Regarding BCSS, the obtained results were similar. Conclusion: The prognosis of patients with discrepant MI and Ki67 appears intermediate between that of low MI/low Ki67 and high MI/high Ki67 groups. These markers should be jointly analysed to clarify prognosis. PMID:26379080

    To determine discrepancies between knowledge and practice of childhood motor vehicle restraints (CMVRs) and vehicle seating position amongst parents within the province of Nova Scotia. Random telephone survey. The Canadian province of Nova Scotia. Four hundred and twenty-six households with at least one child under the age of 12 years, totaling 723 children. The proportion of parents whose children who should be in a specific stage of CMVR and sitting in the rear seat of the vehicle, and who demonstrate correct knowledge of that restraint system and seating position, yet do not use that restraint system/seating position for their child (demonstrate practice discrepant from their knowledge). Awareness of what restraint system to use is good (>80%). However, knowledge of when it is safe to graduate to the next stage is low (30-55%), most marked for when to use a seatbelt alone. Awareness of the importance of sitting in the rear seat of a vehicle was universal. Discrepancies between knowledge and practice were most marked with booster seats and rear-seating of older children. Factors influencing incorrect practice (prematurely graduated to a higher-level restraint system than what is appropriate for age and weight) included lower household income, caregiver education level, and knowledge of when to graduate from forward-facing car seats and booster seats. Incorrect practice was also more commonly observed amongst children of weight and/or age approaching (but not yet reaching) recommended graduation parameters of the appropriate CMVR. Discrepancies between knowledge and practice are evident through all stages of CMVRs, but most marked with booster seats. The roles of lower socioeconomic status and gaps in CMVR legislation, in influencing discrepant practice, must be acknowledged and suggest the need for targeted education concurrent with development of comprehensive all-stages CMVR policies.

    Introduction: Victimization and rejection expectations predict mental health problems in gay and bisexual men. Furthermore, it was shown that victimization predicts rejection expectations. Nevertheless, the levels of these two variables do not necessarily correspond as indicated by low inter-correlations, resulting in the question "How do discrepancies in the two variables relate to mental health problems?" This study tests if non-corresponding levels of victimization and rejection expectations in gay and bisexual men relate to mental health problems differently than corresponding levels of victimization and rejection expectations. It furthermore tests for linear and curvilinear relationships between victimization, rejection expectations, and mental health problems. Methods: Data from N = 1423 gay and bisexual men were obtained online. Victimization and rejection expectations were tested for discrepant values (differing 0.5 SD or more) and those that were in agreement (differing less than 0.5): 33.7% of participants were in agreement, 33.0% reported higher rejection expectations than victimization, and 33.3% v.v. Then, a polynomial regression and a surface analysis were conducted. Results: Discrepant values in victimization and rejection expectations or the direction of the discrepancy did not relevantly predict mental health problems. Findings indicate that victimization and rejection expectations predict mental health problems linearly as well as convexly (upward curving) in gay and bisexual men. Discussion: This study replicates findings that gay and bisexual men with more experiences of victimization and rejection expectations demonstrated more mental health problems. Furthermore, this study is the first one to find a convex relationship between these predictors and mental health problems, implicating that disproportionally high mental health problems exist in those gay and bisexual men with high levels of victimization and rejection expectations.

    Covariate measurement error occurs commonly in survival analysis. Under the proportional hazards model, measurement error effects have been well studied, and various inference methods have been developed to correct for error effects under such a model. In contrast, error-contaminated survival data under the additive hazards model have received relatively less attention. In this paper, we investigate this problem by exploring measurement error effects on parameter estimation and the change of the hazard function. New insights of measurement error effects are revealed, as opposed to well-documented results for the Cox proportional hazards model. We propose a class of bias correction estimators that embraces certain existing estimators as special cases. In addition, we exploit the regression calibration method to reduce measurement error effects. Theoretical results for the developed methods are established, and numerical assessments are conducted to illustrate the finite sample performance of our methods.

    Key place in this paper takes the study of political speech in the Republic of Croatia and their impact on voters, or which keywords are in political speeches and public appearances of politicians in Croatia that their voting body wants to hear. Given listed below we will define the research topic in the form of a question - is there a discrepancy in the perception of the public-political speech in Croatia, and which keywords are specific to the two main regions in Croatia and that inhabitant these regions respond. Marcus Tullius Cicero, the most important Roman orator, he used a specific associative mnemonic technique that is called "technique room". He would talk expound on keywords and conceptual terms that he needed for the desired topic and join in these make them, according to the desired order, in a very creative and unique way, the premises of the house or palace, which he knew well. Then, while holding the speech intended to pass through rooms of the house or palace and then put keywords and concepts come to mind, again according to the desired order. Given that this is a specific kind of research political speech that is relatively recent in Croatia, it should be noted that there is still, this kind of political communication is not sufficiently explored. Particularly the emphasis on the impact and use of keywords specific to the Republic of Croatia, in everyday public and political communication. The paper will be analyzed the political, campaign speeches and promises several winning candidates, and now Croatian MEPs, specific keywords related to: economics, culture, science, education and health. The analysis is based on comparison of the survey results on the representation of key words in the speeches of politicians and qualitative analysis of the speeches of politicians on key words during the election campaign.

    Previous studies have shown depression-like sleep abnormalities in borderline personality disorder (BPD). However, findings in BPD are not unequivocal for REM dysregulation, as well as for a decrement of slow wave sleep and sleep continuity disturbances. Earlier findings in sleep EEG abnormalities in BPD may have been confounded by concomitant depressive symptoms. Twenty unmedicated female BPD patients without current comorbid major depression and 20 sex- and age-matched control subjects entered the study. Conventional polysomnographic parameters and for the first time sleep EEG spectral power analysis was performed on two sleep laboratory nights. Subjective sleep parameters were collected by sleep questionnaires in order to assess the relationship between objective and subjective sleep measurements. BPD patients showed a tendency for shortened REM latency and significantly decreased NonREM sleep (stage 2). Spectral EEG analysis showed increased delta power in total NREM sleep as well as in REM sleep in BPD patients. Subjective ratings documented drastically impaired sleep quality in BPD patients for the two weeks before the study and during the two laboratory nights. Not-depressed BPD patients only showed tendencies for depression-like REM sleep abnormalities. Surprisingly, BPD patients displayed higher levels of delta power in the sleep EEG in NREM sleep than healthy control subjects. There was a marked discrepancy between objective and subjective sleep measurements, which indicates an altered perception of sleep in BPD. The underlying psychological and neurobiological mechanisms of these alterations are still unclear and need to be clarified in future studies including interventions on a pharmacological and cognitive-behavioral level.

    Full Text Available We present a case of fetoplacental discrepancy in a second-trimester fetus with normal karyotype in amniotic fluid and two different Robertsonian translocations in placenta. A 41-year-old woman of Middle-Eastern origin, gravida 2, para 1, underwent amniocentesis at 16-week gestation because of advanced maternal age. Amniotic fluid karyotype showed a normal 46,XX karyotype with a homozygous inv(9. Parental chromosome analysis showed both parents to be carriers of inv(9 and the parents are not consanguineous. Fetal ultrasound was normal. The mother presented to the clinic 4 weeks later with intrauterine fetal demise. Chromosome analysis from the placenta showed two different cell lines: a balanced (15;21 Roberstonian translocation in 11 cells and an unbalanced (21;21 Robertsonian translocation in 9 cells. The karyotype was interpreted as mos 45,XX,inv(9(p11q13x2,der(15;21(q10;q10[11]/46,XX,inv(9(p11q13x2,+21,der(21;21(q10;q10. Mother was a carrier for the Cystic Fibrosis (delta F508, Factor V Leiden mutations, HbD-Los Angeles and HbQ-India variants. She also had a sibling with term stillbirth. Her husband’s history was unremarkable. Our case appears to be another example of confined placental mosaicism (CPM with normal fetal karyotype. However, we could not confirm the possibility that CPM contributed to the IUFD in our case given the complex medical history of the mother.

    Despite the availability of population-based cancer survival data from the developed and developing countries, comparisons remain very few. Such comparisons are important to assess the magnitude of survival discrepancies and to disentangle the impact of ethnic background and health care access on cancer survival. Using the SEER 13 database and databases from the Manila and Rizal Cancer Registries in the Philippines, a 5-year relative survival for 9 common cancers in 1998-2002 of Filipino-American cancer patients were compared with both cancer patients from the Philippines, having the same ethnicity, and Caucasians in the United States, being exposed to a similar societal environment and the same health care system. Survival estimates were much higher for the Filipino-Americans than the Philippine resident population, with particularly large differences (more than 20-30% units) for cancers with good prognosis if diagnosed and treated early (colorectal, breast and cervix), or those with expensive treatment regimens (leukaemias). Filipino-Americans and Caucasians showed very similar survival for all cancer sites except stomach cancer (30.7 vs 23.2%) and leukaemias (37.8 vs 48.4%). The very large differences in the survival estimates of Filipino-Americans and the Philippine resident population highlight the importance of the access to and utilisation of diagnostic and therapeutic facilities in developing countries. Survival differences in stomach cancer and leukaemia between Filipino-Americans and Caucasians in the United States most likely reflect biological factors rather than the differences in access to health care.

    Previous studies applying automatic preprocessing methods on Structural Magnetic Resonance Imaging (sMRI) report inconsistent neuroanatomical abnormalities in Autism Spectrum Disorder (ASD). In this study we investigate inter-method differences as a possible cause behind these inconsistent findings. In particular, we focus on the estimation of the following brain volumes: gray matter (GM), white matter (WM), cerebrospinal fluid (CSF), and total intra cranial volume (TIV). T1-weighted sMRIs of 417 ASD subjects and 459 typically developing controls (TDC) from the ABIDE dataset were estimated using three popular preprocessing methods: SPM, FSL, and FreeSurfer (FS). Brain volumes estimated by the three methods were correlated but had significant inter-method differences; except TIVSPM vs. TIVFS, all inter-method differences were significant. ASD vs. TDC group differences in all brain volume estimates were dependent on the method used. SPM showed that TIV, GM, and CSF volumes of ASD were larger than TDC with statistical significance, whereas FS and FSL did not show significant differences in any of the volumes; in some cases, the direction of the differences were opposite to SPM. When methods were compared with each other, they showed differential biases for autism, and several biases were larger than ASD vs. TDC differences of the respective methods. After manual inspection, we found inter-method segmentation mismatches in the cerebellum, sub-cortical structures, and inter-sulcal CSF. In addition, to validate automated TIV estimates we performed manual segmentation on a subset of subjects. Results indicate that SPM estimates are closest to manual segmentation, followed by FS while FSL estimates were significantly lower. In summary, we show that ASD vs. TDC brain volume differences are method dependent and that these inter-method discrepancies can contribute to inconsistent neuroimaging findings in general. We suggest cross-validation across methods and emphasize the

    Gender discrepancy in the cardiovascular diseases has been evaluated in several studies. We studied the impact of gender disparity on the presentation and outcome of diabetic heart failure (DHF) patients. A retrospective analysis was conducted including all DHF patients admitted to the Heart Hospital between 1991 and 2013. Patients' demographics, presentation, management, and hospital outcomes were analyzed and compared based on gender and age. Out of 8266 HF patients, 4684 (56.7%) were diabetic, of whom 1817 (39%) were females. Mean age was comparable in both genders. DHF female patients were more likely to be hypertensive (79% vs. 65%, P = 0.001) and obese (13% vs. 4.6%, P = 0.001). DHF females were less likely to receive beta-blockers and angiotensin-converting-enzyme inhibitors/angiotensinogen-receptor blockers (25% vs. 30%, P = 0.001, 54% vs. 57%, P = 0.01, respectively), but were more likely to be on insulin therapy (21% vs. 16%, P = 0.001). In-hospital atrial fibrillation (P =0.90), ventricular tachycardia (P = 0.07), stroke (P = 0.45), and cardiac arrest (P = 0.26) were comparable. Overall in-hospital mortality was comparable in both genders (P = 0.83). In age ≤50 years, male gender was associated with a 3-fold increase in death (13% vs. 4%, P = 0.01), however, this mortality difference disappeared in DHF patients aged >50 years (P = 0.62). In DHF, female gender is characterized by having a high prevalence of metabolic syndrome components. Also, females are more likely to have better Left ventricular ejection fraction but less likely to receive cardiovascular evidence based medications. There is no significant difference in the overall hospital mortality between both genders, however, in the younger age; males have a significantly higher mortality.

  15. On the discrepancy in measurement of Q using surface waves and normal modes

    2012-12-01

    We revisit the decade-old unsolved problem of why measurements of the quality factor (Q) for fundamental mode propagating Rayleigh waves differs by up to 20% from that measured using normal modes, in the frequency band where both approaches are possible. Surface wave measurements consistently yield lower Q values than modes. Since it is unclear which measurement is more accurate, this is currently a limitation on the resolution of 1D average Q profiles in the Earth, compounded by the fact that the measurement bias may not only affect the region of the spectrum where both methods are available but every Q measurement that is based upon one or the other of the mentioned techniques. We investigate the effect of elastic focussing and defocussing on long time series using a spectral element method that we have shown to be accurate enough for the relevant period ranges and the necessarily long time series. While previous investigations are based upon approximate methods that are only valid for smooth 3D models and weak heterogeneities, the SEM allows us to estimate the effect of more realistic distributions of heterogeneities on amplitude measurements, and therefore Q. Our investigations show a bias towards lower Q in the first arriving surface wave trains and a bias towards higher Q in later arrivals which could explain the mode surface-wave discrepancy. Heuristically this can be explained by the fact that energy that has been scattered off the great circle path is brought back into the great circle after multiple-orbits, leading to increased amplitude in late arrivals. Further we reinvestigate the effects of noise that predominantly influences the later part of the seismogram, the effect of post-processing as well as mode amplitude modulations that could potentially bias the measurements. We plan to present preliminary results on applying our insights to debias real data and reduce the error bounds on 1D Q models from normal modes and surface waves.

    A noninvasive computer-aided-theragnosis (CAT) system was developed for the early therapeutic cancer response assessment in patients with locally advanced breast cancer (LABC) treated with neoadjuvant chemotherapy. The proposed CAT system was based on multi-parametric quantitative ultrasound (QUS) spectroscopic methods in conjunction with advanced machine learning techniques. Specifically, a kernel-based metric named maximum mean discrepancy (MMD), a technique for learning from imbalanced data based on random undersampling, and supervised learning were investigated with response-monitoring data from LABC patients. The CAT system was tested on 56 patients using statistical significance tests and leave-one-subject-out classification techniques. Textural features using state-of-the-art local binary patterns (LBP), and gray-scale intensity features were extracted from the spectral parametric maps in the proposed CAT system. The system indicated significant differences in changes between the responding and non-responding patient populations as well as high accuracy, sensitivity, and specificity in discriminating between the two patient groups early after the start of treatment, i.e., on weeks 1 and 4 of several months of treatment. The proposed CAT system achieved an accuracy of 85%, 87%, and 90% on weeks 1, 4 and 8, respectively. The sensitivity and specificity of developed CAT system for the same times was 85%, 95%, 90% and 85%, 85%, 91%, respectively. The proposed CAT system thus establishes a noninvasive framework for monitoring cancer treatment response in tumors using clinical ultrasound imaging in conjunction with machine learning techniques. Such a framework can potentially facilitate the detection of refractory responses in patients to treatment early on during a course of therapy to enable possibly switching to more efficacious treatments.

  17. Emergence of the mass discrepancy-acceleration relation from dark matter-baryon interactions

    2018-03-01

    The observed tightness of the mass discrepancy-acceleration relation (MDAR) poses a fine-tuning challenge to current models of galaxy formation. We propose that this relation could arise from collisional interactions between baryons and dark matter (DM) particles, without the need for modification of gravity or ad hoc feedback processes. We assume that these interactions satisfy the following three conditions: (i) the relaxation time of DM particles is comparable to the dynamical time in disk galaxies; (ii) DM exchanges energy with baryons due to elastic collisions; (iii) the product between the baryon-DM cross section and the typical energy exchanged in a collision is inversely proportional to the DM number density. As a proof of principle, we present an example of a particle physics model that gives a DM-baryon cross section with the desired density and velocity dependence. For consistency with direct detection constraints, our DM particles must be either very light (m ll mb) or very heavy (mgg mb), corresponding respectively to heating and cooling of DM by baryons. In both cases, our mechanism applies and an equilibrium configuration can in principle be reached. In this exploratory paper, we focus on the heavy DM/cooling case because it is technically simpler, since the average energy exchanged turns out to be approximately constant throughout galaxies. Under these assumptions, we find that rotationally-supported disk galaxies could naturally settle to equilibrium configurations satisfying a MDAR at all radii without invoking finely tuned feedback processes. We also discuss issues related to the small scale clumpiness of baryons, as well as predictions for pressure-supported systems. We argue in particular that galaxy clusters do not follow the MDAR despite being DM-dominated because they have not reached their equilibrium configuration. Finally, we revisit existing phenomenological, astrophysical and cosmological constraints on baryon-DM interactions in light

  18. FABP4 dynamics in obesity: discrepancies in adipose tissue and liver expression regarding circulating plasma levels.

    Directory of Open Access Journals (Sweden)

    María Isabel Queipo-Ortuño

    Full Text Available BACKGROUND: FABP4 is predominantly expressed in adipose tissue, and its circulating levels are linked with obesity and a poor atherogenic profile. OBJECTIVE: In patients with a wide BMI range, we analyze FABP4 expression in adipose and hepatic tissues in the settings of obesity and insulin resistance. Associations between FABP4 expression in adipose tissue and the FABP4 plasma level as well as the main adipogenic and lipolytic genes expressed in adipose tissue were also analyzed. METHODS: The expression of several lipogenic, lipolytic, PPAR family and FABP family genes was analyzed by real time PCR. FABP4 protein expression in total adipose tissues and its fractions were determined by western blot. RESULTS: In obesity FABP4 expression was down-regulated (at both mRNA and protein levels, with its levels mainly predicted by ATGL and inversely by the HOMA-IR index. The BMI appeared as the only determinant of the FABP4 variation in both adipose tissue depots. FABP4 plasma levels showed a significant progressive increase according to BMI but no association was detected between FABP4 circulating levels and SAT or VAT FABP4 gene expression. The gene expression of FABP1, FABP4 and FABP5 in hepatic tissue was significantly higher in tissue from the obese IR patients compared to the non-IR group. CONCLUSION: The inverse pattern in FABP4 expression between adipose and hepatic tissue observed in morbid obese patients, regarding the IR context, suggests that both tissues may act in a balanced manner. These differences may help us to understand the discrepancies between circulating plasma levels and adipose tissue expression in obesity.

    Nonheterosexual youth are at greater risk for mental and physical health problems than heterosexual youth. Definitions of nonheterosexual youth, however, are not consistent between studies, variably including sexual identity, attraction, and/or behavior. This study's objective was to describe the concordance and discrepancy between sexual identification, attraction, and behavior in adolescents. A total of 1,951 students aged 14 and older from 14 high schools in Montreal, Quebec, were surveyed anonymously using the Quebec Youth Risk Behaviour Survey. The survey included three items assessing sexual orientation (sexual identity, sexual attraction, sexual behavior). Twelve percent of adolescents (n=237) endorsed at least one measure of nonexclusive heterosexuality. A total of 3.4% reported gay/lesbian or bisexual (GLB) identity (another 3.4% were unsure), 9.0% reported same-gender attraction, and 4.0% same-gender behavior. There was no consistent pattern of overlap between the three measures, and no single dimension effectively captured this population. The question about attraction identified 71%; identity identified 52%; and behavior only 31%. In raw numbers, more heterosexually identified students reported same-gender attraction (n=95) or same-gender behavior (n=33) than GLB-identified students (n=44 and 29, respectively). "Nonheterosexual" youth are a heterogeneous group that cannot be identified accurately using a single question. In both research and clinical settings, the best way to assess sexual orientation, consistent with American Academy of Pediatrics, is to ask multiple questions that address the dimensions of identity, attraction, and behavior. All youth who endorse any combination of nonexclusively heterosexual identity, behavior, or attraction are potentially at risk for the ill effects of direct and indirect discrimination.

  20. Quantifying mRNA and microRNA with qPCR in cervical carcinogenesis: a validation of reference genes to ensure accurate data.

    Directory of Open Access Journals (Sweden)

    Maria da Conceição Gomes Leitão

    Full Text Available A number of recent studies have catalogued global gene expression patterns in a panel of normal, tumoral cervical tissues so that potential biomarkers can be identified. The qPCR has been one of the most widely used technologies for detecting these potential biomarkers. However, few studies have investigated a correct strategy for the normalization of data in qPCR assays for cervical tissues. The aim of this study was to validate reference genes in cervical tissues to ensure accurate quantification of mRNA and miRNA levels in cervical carcinogenesis. For this purpose, some issues for obtaining reliable qPCR data were evaluated such as the following: geNorm analysis with a set of samples which meet all of the cervical tissue conditions (Normal + CIN1 + CIN2 + CIN3 + Cancer; the use of individual Ct values versus pooled Ct values; and the use of a single (or multiple reference genes to quantify mRNA and miRNA expression levels. Two different data sets were put on the geNorm to assess the expression stability of the candidate reference genes: the first dataset comprised the quantities of the individual Ct values; and the second dataset comprised the quantities of the pooled Ct values. Moreover, in this study, all the candidate reference genes were analyzed as a single "normalizer". The normalization strategies were assessed by measuring p16INK4a and miR-203 transcripts in qPCR assays. We found that the use of pooled Ct values, can lead to a misinterpretation of the results, which suggests that the maintenance of inter-individual variability is a key factor in ensuring the reliability of the qPCR data. In addition, it should be stressed that a proper validation of the suitability of the reference genes is required for each experimental setting, since the indiscriminate use of a reference gene can also lead to discrepant results.

    Physical inactivity is associated with obesity and type 2 diabetes. A key obstacle to physical activity is lack of motivation. Although some interactive exercise games (i.e., exergames--video games that require physical exertion in order to play) motivate players to exercise more, few games take advantage of group dynamics to motivate players' duration of exercise. In a test of the Köhler motivation gain effect, this study varied the ability level of a virtually presented partner in an interactive exergame that focused on abdominal strength to identify effects on a subject's (S') persistence with the task. Male (n = 63) and female (n = 72) undergraduate students were randomly assigned to one of four conditions (individual control or low-, moderate-, or high- partner discrepancy) in a conditions × gender factorial design and tested on a series of isometric abdominal exercises using PlayStation 2 EyeToy: Kinetic software. They performed the first series of five exercises alone (trial block 1), and after a rest period, those in the partner conditions performed remaining trials (trial block 2) with a same-sex virtually presented partner whom they could observe during their performance, while those in the individual control condition performed the remaining trials alone. In the partner conditions, the partner's performance was manipulated to be always better than the S's, the exact difference depending on the discrepancy condition. The partnered tasks were conjunctive; that is, success in the game depended on the performance of the weaker team member. Persistence, the outcome measure for this study, consisted of the total number of seconds the S held the exercise position. Using planned orthogonal contrasts on difference scores between blocks 1 and 2, results showed that persistence was significantly (p < .001) greater in all experimental conditions with a virtually presented partner (M = 33.59 s) than in the individual control condition (M = -49.04 s).

    INTRODUCTION: Telemedicine is often seen as the solution to the challenge of providing health care for an increasing number of people with chronic conditions. Projects are often organised locally and based on the involvement of stakeholders with a wide range of backgrounds. It can be challenging...... to ensure that projects are based on previous experience and that they do not repeat previous studies. To better understand these challenges and current practice, we examined telemedicine projects funded in the 2008-2010 period to explore where, how and to what extent results from the projects were....... The investigators should ensure proper documentation and dissemination of changes both during and after the projects in order to ensure transparency, and national or international organisations should establish a database with relevant data fields. FUNDING: not relevant. TRIAL REGISTRATION: not relevant....

    2016-12-01

    Full Text Available The forelimbs and hindlimbs of vertebrates are bilaterally symmetric. The mechanisms that ensure symmetric limb formation are unknown but they can be disrupted in disease. In Holt-Oram Syndrome (HOS, caused by mutations in TBX5, affected individuals have left-biased upper/forelimb defects. We demonstrate a role for the transcription factor Tbx5 in ensuring the symmetric formation of the left and right forelimb. In our mouse model, bilateral hypomorphic levels of Tbx5 produces asymmetric forelimb defects that are consistently more severe in the left limb than the right, phenocopying the left-biased limb defects seen in HOS patients. In Tbx hypomorphic mutants maintained on an INV mutant background, with situs inversus, the laterality of defects is reversed. Our data demonstrate an early, inherent asymmetry in the left and right limb-forming regions and that threshold levels of Tbx5 are required to overcome this asymmetry to ensure symmetric forelimb formation.

    Wireless technologies as part of the data communication infrastructure of modern hospitals are being rapidly introduced. Even though there are concerns about problems associated with wireless communication security, the demand is remarkably large. Herein we discuss security countermeasures that must be taken and issues concerning availability that must be considered to ensure safe hospital/business use of wireless LAN systems, referring to the procedures introduced at a university hospital. Security countermeasures differ according to their purpose, such as preventing illegal use or ensuring availability, both of which are discussed. The main focus of the availability discussion is on signal reach, electromagnetic noise elimination, and maintaining power supply to the network apparatus. It is our hope that this information will assist others in their efforts to ensure safe implementation of wireless LAN systems, especially in hospitals where they have the potential to greatly improve information sharing and patient safety.

    This study tested the reciprocal relationships between automatic thoughts about eating and the actual-ideal weight discrepancies, and their role in the formation and maintenance of eating disorders (ED) symptoms in a non-clinical sample of adolescents. In particular, we investigated whether thoughts about eating mediated the effects of weight discrepancies on ED formation and whether weight discrepancies mediated the effects of thoughts about eating on ED formation were investigated. Data were collected three times, with a 2-month interval between Time 1 (T1) and Time 2 (T2), and a 9-month interval between T2 and Time 3 (T3). Adolescents (N = 55) aged 15-18 filled out the SCOFF Questionnaire, assessing eating disorders symptoms, and the Eating Disorder Thoughts Questionnaire, evaluating automatic thoughts. To assess weight discrepancies questions about actual (subjectively reported) and ideal body weight were asked followed by objective measurement of height and weight. Negative thoughts about eating (T2) mediated the relation between weight discrepancies (T1) and symptoms of anorexia and bulimia (T3). In addition, the association between negative thoughts (T1) and eating disorders symptoms (T3) was mediated by weight discrepancies (T2). The negative thoughts and the actual (both subjectively reported and objectively measured)-ideal weight discrepancies constitute a vicious cycle, related to higher ED symptoms. Prevention of eating disorders should be directed to adolescents who manifest large weight discrepancies or high levels of negative thoughts about eating, as they are at risk for developing eating disorder symptoms.

    To ensure the highest standards for publication, AGU has begun screening manuscript submissions using CrossCheck (http://www.crossref.org/crosscheck.html) for possible verbatim use of previously published material. Water Resources Research and Geophysical Research Letters have tested this technology since summer 2010. It has proven very useful in ensuring the highest integrity in publication standards and compliance with the AGU dual publication policy (http://www.agu.org/pubs/authors/policies/dualpub_policy.shtml). According to Barbara Major, assistant director of journals, other AGU journals will adopt this screening process in the near future.

    Research in younger adults suggests sleep discrepancy (objective/subjective measurement difference) is a consistent pattern that primarily occurs within individuals with insomnia. To examine whether older adults exhibit a similar pattern, this study compared night-to-night inconsistency in sleep discrepancy between older adults with and without sleep complaints. Older adults (N = 103; mean age = 72.81, SD = 7.12) wore an Actiwatch-L® (24 hr per day) and concurrently completed sleep diaries for 14 days. Sleep discrepancy = diary (sleep onset latency [SOL] or wake [time] after sleep onset [WASO]) - actigraphy (SOL or WASO). Both groups exhibited sleep discrepancy, but complainers exhibited significantly more night-to-night variability. Sleep discrepancy was a variable behavior that was not limited to insomnia, but instead manifested by degree throughout our older sample. Greater attention to variability in sleep research and clinical practice is warranted.

    To compare the filling out of the prenatal care card of pregnant women at a school-service and other services, as well as to verify the concordance between these records and verbal information provided by the puerperae. A two-stage epidemiological, cross-sectional study was performed with stratified sampling, proportional to number of births. In the first stage, the information recorded on the prenatal care card in the school-service was compared to that recorded in units not linked to higher health education in Recife (PE). In the second stage, the information about prenatal care was collected with a semi-structured questionnaire applied to women during the puerperal period. A total of 262 puerperae older than 19 years, who had a prenatal care card at the time of delivery were included in the study from May to July 2008. Data were analyzed statistically by the χ(2) test, Student's t-test or Mann-Whitney test, all one-sided to the right, with the level of significance set at 5%. The information more often recorded on the prenatal care card in the school-service was: schooling (86.5 versus 70.3%; p=0.002), marital status, (83.7 versus 70.9%; p=0.01), weight prior to pregnancy (72.1 versus 46.8%; p<0.001), height (62.5 versus 45.6%; p=0.007), and educational practices (76.9 versus 11.4%; p<0.001) and, at other services, only birth weight <2,500 g (15.4 versus 27.2% at the school-service; p=0.02). There were significant discrepancies between data obtained by verbal information and the prenatal care records of the pregnant women. At the school-service, 40.3% of pregnant women received adequate prenatal care versus 20.3% at other units. In all services, there was a predominance of recorded information directly related to delivery, while information about actions with preventive characteristics during prenatal care was neglected.

    Liquid water flow in snowpacks is a complicated process to measure or to simulate in snowpack models, although it is important for assessing, for example, soil moisture variations, streamflow discharge or wet snow avalanche formation. The measurement site Weissfluhjoch (WFJ) is equipped with instruments recording meteorological conditions and snowpack properties, including a snow lysimeter and an upward looking ground penetrating radar (upGPR). The upGRP, among other capabilities, is able to track the progress of the melt water front through the seasonal snowpack at WFJ, whereas the snow lysimeter only records liquid water runoff from the snowpack. The 1 dimensional physics-based snowpack model SNOWPACK has recently been extended with a solver for Richards equation, which provides a demonstrable improvement in simulating snowpack runoff, especially on the hourly time scale, when compared to a simpler bucket-type approach. Here, we compare the two measurement methods and the two snowpack simulations for four snow seasons with respect to the progress of the melt water front through the snowpack and snowpack runoff. We show that in the studied period, snowpack runoff in the melt season starts before the arrival of the melt water front at the bottom of the snowpack as detected by the upGPR. This discrepancy is in the order of several days to 1-2 weeks. The agreement between measured and modeled snowpack runoff is higher, although modeled snowpack runoff is still lagging several days from observed runoff, depending on the used water transport scheme. This demonstrates that the early start of snowpack runoff is likely associated with the existence of preferential flow paths. The modeled progress of the melt water front is faster than observed in the upGPR data. This contributes to a better predicition of the onset of snowpack runoff, but may have consequences for the representation of the internal snowpack in the model. The study highlights the extreme difficulties in

    Full Text Available Abstract Background Anopheles gambiae M and S molecular forms, the major malaria vectors in the Afro-tropical region, are ongoing a process of ecological diversification and adaptive lineage splitting, which is affecting malaria transmission and vector control strategies in West Africa. These two incipient species are defined on the basis of single nucleotide differences in the IGS and ITS regions of multicopy rDNA located on the X-chromosome. A number of PCR and PCR-RFLP approaches based on form-specific SNPs in the IGS region are used for M and S identification. Moreover, a PCR-method to detect the M-specific insertion of a short interspersed transposable element (SINE200 has recently been introduced as an alternative identification approach. However, a large-scale comparative analysis of four widely used PCR or PCR-RFLP genotyping methods for M and S identification was never carried out to evaluate whether they could be used interchangeably, as commonly assumed. Results The genotyping of more than 400 A. gambiae specimens from nine African countries, and the sequencing of the IGS-amplicon of 115 of them, highlighted discrepancies among results obtained by the different approaches due to different kinds of biases, which may result in an overestimation of MS putative hybrids, as follows: i incorrect match of M and S specific primers used in the allele specific-PCR approach; ii presence of polymorphisms in the recognition sequence of restriction enzymes used in the PCR-RFLP approaches; iii incomplete cleavage during the restriction reactions; iv presence of different copy numbers of M and S-specific IGS-arrays in single individuals in areas of secondary contact between the two forms. Conclusions The results reveal that the PCR and PCR-RFLP approaches most commonly utilized to identify A. gambiae M and S forms are not fully interchangeable as usually assumed, and highlight limits of the actual definition of the two molecular forms, which might

    This study examined convergence between indicators of infant temperament derived via parent-report and those obtained in the context of structured laboratory observations. Discrepancies between scores resulting form these methodological approaches were examined in an attempt to explain these differences by considering multiple reporter (i.e., parent) characteristics. Convergence between the two sources of information was hypothesized; however, discrepancies were also expected. This study was aimed at examining whether increased maternal depression and low parenting self-efficacy were related to higher levels of infant fear and decreased positive affectivity, as reported by mothers, relative to the scores derived from the laboratory procedure. Results indicated that the fear scores based on parent-report and structured observations, respectively, were significantly correlated; however, the correlation for smiling and laughter scores did not reach statistical significance. Furthermore, parents higher in negative affect reported a higher level of fear for their infants, relative to the results of the laboratory observation. PMID:18082892

    Studies have suggested associations between personality dimensions and body image constructs, but these have not been conclusively established. In two studies, we examined direct associations between the Big Five dimensions and two body image constructs, actual-ideal weight discrepancy and body appreciation. In Study 1, 950 women completed measures of both body image constructs and a brief measure of the Big Five dimensions. In Study 2,339 women completed measures of the body image constructs and a more reliable measure of the Big Five. Both studies showed that Neuroticism was significantly associated with actual-ideal weight discrepancy (positively) and body appreciation (negatively) once the effects of body mass index and social status had been accounted for. These results are consistent with the suggestion that Neuroticism is a trait of public health significance requiring attention by body image scholars. © 2012 The Authors.

    GPS availability and signal strength originally specified for users on or near surface of Earth with transmitted power levels specified at edge-of-Earth, 14.3 degrees. Prior to the SSV specification, on-orbit performance of GPS varied from block build to block build (IIA, IIRM, IIF) due to antenna gain and beam width variances. Unstable on-orbit performance results in significant risk to space users. Side-lobe signals, although not specified, were expected to significantly boost GPS signal availability for users above the constellation. During GPS III Phase A, NASA noted significant discrepancies in power levels specified in GPS III specification documents, and measured on-orbit performance. To stabilize the signal for high altitude space users, NASA DoD team in 2003-2005 led the creation of new Space Service Volume (SSV) definition and specifications.

    Dental laboratories use different computer-aided design and computer-aided manufacturing (CAD-CAM) systems to fabricate fixed prostheses; however, limited evidence is available concerning which system provides the best marginal discrepancy. The purpose of this in vitro study was to evaluate the marginal fit of 5 different monolithic zirconia restorations milled with different CAD-CAM systems. Thirty monolithic zirconia crowns were fabricated on a custom-designed stainless steel die and were divided into 5 groups according to the type of monolithic zirconia crown and the CAD-CAM system used: group TZ, milled with an MCXL milling machine; group CZ, translucent zirconia milled with a motion milling machine; group ZZ, zirconia milled with a dental milling unit; group PZ, translucent zirconia milled with a zirconia milling unit; and group BZ, solid zirconia milled using an S1 VHF milling machine. The marginal fit was measured with a binocular microscope at an original magnification of ×100. The results were tabulated and statistically analyzed with 1-way ANOVA and post hoc surface range test, and pairwise multiple comparisons were made using Bonferroni correction (α=.05). The type of CAD-CAM used affected the marginal fit of the monolithic restoration. The mean (±SD) highest marginal discrepancy was recorded in group TZI at 39.3 ±2.3 μm, while the least mean marginal discrepancy was recorded in group IZ (22.8 ±8.9 μm). The Bonferroni post hoc test showed that group TZI was significantly different from all other groups tested (Pzirconia restorations with clinically acceptable marginal discrepancies; however, the CAD-CAM system with the 5-axis milling unit produced the best marginal fit.

    The relationship between filial piety and depressive symptoms has been widely discussed, but limited research focused on the gap between filial expectations and filial receipt. This study aims to investigate the association between filial discrepancy and depressive symptoms. Data were derived from the Population Study of Chinese Elderly (PINE), a community-engaged, population-based epidemiological study of U.S. Chinese older adults aged 60 and older in the greater Chicago area. Depressive symptoms were measured by the Patient Health Questionnaire-9. Overall filial discrepancy was evaluated by filial receipt minus expectations. Levels of overall filial discrepancy divided older adults into four groups based on the medium value of filial expectations and receipt. Logistic regression analyses were performed. Older adults with greater filial receipt than expectations were more likely to have lower risk of depressive symptoms (odds ratio [OR], 0.95 [0.92-0.97]). The group with high expectations and low receipt has the highest risk of depressive symptoms among the four groups (OR, 1.51 [1.07-2.13]). Greater receipt than expectations in care (OR, 0.83 [0.76-0.92]), make happy (OR, 0.77 [0.69-0.86]), greet (OR, 0.88 [0.79-0.97]), obey (OR, 0.76 [0.68-0.86]), and financial support (OR, 0.80 [0.71-0.89]) was associated with lower risk of depressive symptoms. This study goes beyond previous research by examining the association between filial discrepancy domains and depressive symptoms. Cultural relevancy of health interventions is important in the context of Chinese communities. Health care professionals are suggested to be aware of the depressive symptoms of U.S. Chinese older adults with high filial expectations and low receipt. © The Author 2017.

    Full Text Available Abstract Background Discrepancies between parents and children in their assessment of children's mental health affect the evaluation of need for services and must be taken seriously. This article presents the differences between parents' and children's reports of the children's symptoms and social impairment, based on the results of the Strengths and Difficulties Questionnaire (SDQ. The interrelationship between relational aspects and socio-demographic factors with patterns of disagreement are explored. Methods Differences in the prevalence and means of SDQ symptom and impact scores were obtained from 8,154 primary school children, aged between 10 and 13 years, and their parents. Agreement between matched pairs was measured using Pearson's and Spearman's rho correlations. Socio-demographic variables, communication patterns and parental engagement were analysed as possible correlates of informant discrepancies using bivariate and multivariate logistic regression models. Results In general, although children reported more symptoms, they reported less impact of perceived difficulties than parents. The parents were more consistent in their evaluation of symptoms and impact than were the children. Exploration of highly discrepant subgroups showed that, when children reported the most symptoms and impact, qualitative aspects of the parent-child relationship and family structure seemed to be more powerful predictors of disagreement than were gender of the child and socio-demographic variables. When parents reported the most symptoms and impact, low parental educational level, low income and male gender of the child played an additional role. Conclusions Our findings underline the importance of paying attention to child reports of emotional-behavioural difficulties, particularly when parents do not identify these problems.

    University students are supposed to be autonomous learners, able to adapt to an educational environment significantly less guided than school. Entering higher education poses a challenge of self-regulation, in which beginning students are often not prepared with self-regulation strategies needed. Since there are many studies assessing self-regulated learning (SRL) via classical self-reports, we know a lot about how students generally self-assess their SRL strategies. However, SRL and performance do not always correlate highly in these studies. The aim of the present study is to determine whether there are discrepancies between students' knowledge about SRL and their action in applying adequate SRL strategies in relevant learning situations. We also want to know whether such discrepancies generalize across domains and what the reasons for discrepancies are. The situation-specific Self-Regulated Learning Questionnaire for Action and Knowledge (SRL-QuAK) was used in a sample of 408 psychology and economic sciences students. Descriptive data analysis was conducted to determine potential discrepancies between SRL knowledge and action and differences between the study domains in an explorative way. The reasons for not using SRL-strategies were derived via qualitative content analysis. The results showed that although students had quite advanced knowledge of SRL strategies, they did not put this knowledge into action. This dissonance between SRL knowledge and action was found in both domains. In terms of reasons, students stated that they (a) lacked the time to use SRL strategies, (b) would not benefit from SRL strategies in the given situation, (c) would not be able to put the strategies to use effectively or (d) found it too arduous to use SRL strategies. The implications of these results will be discussed, e.g., the consequences for measures to overcome students' dissonance between knowledge and action and therefore to promote academic performance and well-being.

    Following from previous research on intensity bias and the accessibility model of emotional self-report, the present study examined the role of emotional exhaustion in explaining the discrepancy in teachers' reports of their trait (habitual) versus state (momentary, "real") emotions. Trait reports (habitual emotions, exhaustion) were assessed via trait questionnaires, and state reports (momentary emotions) were assessed in real time via the experience sampling method by using personal digital...

    We sought to compare maximal left ventricular (LV) wall thickness (WT) measurements as obtained by routine clinical practice between echocardiography and cardiac magnetic resonance (CMR) and document causes of discrepancy. One-hundred and ninety-five patients with hypertrophic cardiomyopathy (median age, 52.8±15.1 years) who underwent echocardiography and CMR imaging within 6 months (median, 41 days; interquartile range, 16-97 days) were included. LVWT was assessed in parasternal long and short axis by 2-dimensional echocardiography and in short axis by CMR. By Bland-Altman plot, mean maximal LVWT difference between echocardiography and CMR was 0.5 mm (95% confidence interval, -6.9, 7.8) with equal distribution of discrepancy along the full range of LVWT. Ninety-seven patients (49.7%) were identified to have intermodal measurement discrepancies ≥10%. In 7 patients (7.2%), reported measurement by CMR was inaccurate because of interpretation error. In 90 patients (92.8%), echocardiography underestimated (n=32; 33.0%) or overestimated (n=58; 59.8%) maximal LVWT. Underestimation was because of focal LV hypertrophy (n=10; 10.3%) or poor acoustic windows (n=22; 22.7%) while overestimation resulted from inclusion of right ventricular myocardium (n=37; 38.1%), LV trabeculations (n=5; 5.2%), papillary muscle (n=3; 3.1%), and apical-septal bundle (n=1; 1.0%), as well as imaging plane obliquity (n=7; 12.5%). In 31 (15.9%) patients, measurement discrepancy occurred at diagnostic or prognostic cut-offs. Although maximal LVWT by echocardiography in general measured similar to CMR, discordance because of limitations in echocardiography technique was present in a significant subset of patients. As measurement of LVWT impacts diagnosis and sudden death management, CMR should be considered as part of routine evaluation of all patients with hypertrophic cardiomyopathy. © 2017 American Heart Association, Inc.

    Discrepancies between parents and children in their assessment of children's mental health affect the evaluation of need for services and must be taken seriously. This article presents the differences between parents' and children's reports of the children's symptoms and social impairment, based on the results of the Strengths and Difficulties Questionnaire (SDQ). The interrelationship between relational aspects and socio-demographic factors with patterns of disagreement are explored. Differences in the prevalence and means of SDQ symptom and impact scores were obtained from 8,154 primary school children, aged between 10 and 13 years, and their parents. Agreement between matched pairs was measured using Pearson's and Spearman's rho correlations. Socio-demographic variables, communication patterns and parental engagement were analysed as possible correlates of informant discrepancies using bivariate and multivariate logistic regression models. In general, although children reported more symptoms, they reported less impact of perceived difficulties than parents. The parents were more consistent in their evaluation of symptoms and impact than were the children. Exploration of highly discrepant subgroups showed that, when children reported the most symptoms and impact, qualitative aspects of the parent-child relationship and family structure seemed to be more powerful predictors of disagreement than were gender of the child and socio-demographic variables. When parents reported the most symptoms and impact, low parental educational level, low income and male gender of the child played an additional role. Our findings underline the importance of paying attention to child reports of emotional-behavioural difficulties, particularly when parents do not identify these problems.

    Aim: To assess the effect on radiologist participation in learning from discrepancy meetings (LDMs) in a multisite radiology department by establishing virtual LDMs using OsiriX (Pixmeo). Materials and methods: Sets of anonymised discrepancy cases were added to an OsiriX database available for viewing on iMacs in all radiology reporting rooms. Radiologists were given a 3-week period to review the cases and send their feedback to the LDM convenor. Group learning points and consensus feedback were added to each case before it was moved to a permanent digital LDM library. Participation was recorded and compared with that from the previous 4 years of conventional LDMs. Radiologist feedback comparing the two types of LDM was collected using an anonymous online questionnaire. Results: Numbers of radiologists attending increased significantly from a mean of 12±2.9 for the conventional LDM to 32.7±7 for the virtual LDM (p<0.0001) and the percentage of radiologists achieving the UK standard of participation in at least 50% of LDMs annually rose from an average of 18% to 68%. The number of cases submitted per meeting rose significantly from an average of 11.1±3 for conventional LDMs to 15.9±5.9 for virtual LDMs (p<0.0097). Analysis of 35 returned questionnaires showed that radiologists welcomed being able to review cases at a time and place of their choosing and at their own pace. Conclusion: Introduction of virtual LDMs in a multisite radiology department improved radiologist participation in shared learning from radiological discrepancy and increased the number of submitted cases. - Highlights: • Learning from error is an important way to improve patient safety. • Consultant attendance at learning from discrepancy meetings (LDMs) was persistently poor in a large, multisite Trust. • Introduction of a ‘virtual’ LDM improved consultant participation and increased the number of cases submitted.

    ABO blood typing in pre-transfusion testing is a major component of the high workload in blood banks that therefore requires automation. We often experienced discrepant results from an automated system, especially weak serum reactions. We evaluated the discrepant results by the reference manual method to confirm ABO blood typing. In total, 13,113 blood samples were tested with the AutoVue system; all samples were run in parallel with the reference manual method according to the laboratory protocol. The AutoVue system confirmed ABO blood typing of 12,816 samples (97.7%), and these results were concordant with those of the manual method. The remaining 297 samples (2.3%) showed discrepant results in the AutoVue system and were confirmed by the manual method. The discrepant results involved weak serum reactions (serum reactions, samples from patients who had received stem cell transplants, ABO subgroups, and specific system error messages. Among the 98 samples showing ≤1+ reaction grade in the AutoVue system, 70 samples (71.4%) showed a normal serum reaction (≥2+ reaction grade) with the manual method, and 28 samples (28.6%) showed weak serum reaction in both methods. ABO blood tying of 97.7% samples could be confirmed by the AutoVue system and a small proportion (2.3%) needed to be re-evaluated by the manual method. Samples with a 2+ reaction grade in serum typing do not need to be evaluated manually, while those with ≤1+ reaction grade do.

  15. Parametric model measurement: reframing traditional measurement ideas in neuropsychological practice and research.

    Brown, Gregory G; Thomas, Michael L; Patt, Virginie

    Neuropsychology is an applied measurement field with its psychometric work primarily built upon classical test theory (CTT). We describe a series of psychometric models to supplement the use of CTT in neuropsychological research and test development. We introduce increasingly complex psychometric models as measurement algebras, which include model parameters that represent abilities and item properties. Within this framework of parametric model measurement (PMM), neuropsychological assessment involves the estimation of model parameters with ability parameter values assuming the role of test 'scores'. Moreover, the traditional notion of measurement error is replaced by the notion of parameter estimation error, and the definition of reliability becomes linked to notions of item and test information. The more complex PMM approaches incorporate into the assessment of neuropsychological performance formal parametric models of behavior validated in the experimental psychology literature, along with item parameters. These PMM approaches endorse the use of experimental manipulations of model parameters to assess a test's construct representation. Strengths and weaknesses of these models are evaluated by their implications for measurement error conditional upon ability level, sensitivity to sample characteristics, computational challenges to parameter estimation, and construct validity. A family of parametric psychometric models can be used to assess latent processes of interest to neuropsychologists. By modeling latent abilities at the item level, psychometric studies in neuropsychology can investigate construct validity and measurement precision within a single framework and contribute to a unification of statistical methods within the framework of generalized latent variable modeling.

  16. Memory score discrepancies by healthy middle-aged and older individuals: the contributions of age and education.

    The aim of this study was to examine discrepancies between immediate/delayed recall and recall/working memory in middle-aged and older persons by age and education. Participants were 322 healthy individuals from the community who were stratified into three age and three education groups. Immediate and delayed recall distributions of WMS-III Logical Memory (LM) scores approximated normal curves, and LM savings scores showed a significant, but small, effect of age. LM (immediate, delayed) and Letter-Number Sequencing (LNS) discrepancies varied as a function of age and education. The difference between LM and LNS was not significant in the younger and less educated participants, but increased with age in the most educated group, and in the oldest group LNS exceeded LM (immediate and delayed). The results indicate deterioration in encoding and retrieval, rather than storage, with age, and show a differential, but small, effect of age and education on the memory measures. Working memory was resistant to age-related decline relative to immediate and delayed recall in the oldest, most educated group. Delayed recall-working memory discrepancy is relatively stable with age and education and may be a useful index of the onset of memory pathology across different ages and levels of education.

    Psychosocial factors, such as gender role norms, may impact how social anxiety disorder (SAD) is experienced and expressed in different social contexts for women. However to date, these factors have not been examined via experimental methodology. This was a cross-sectional, quasi-experimental controlled study. The current study included 48 highly socially anxious (HSA) women (70.9% meeting criteria for SAD) and examined the relationships among psychosocial factors (i.e. gender role self-discrepancies and self-perceived physical attractiveness), self-perceived social performance, and state anxiety, across two in vivo social tasks (i.e. conversation and opinion speech). On average, participants reported belief that they ought to be less feminine for the speech task and more masculine for both the conversation and speech tasks. Also, for the conversation task, only lower self-rated attractiveness predicted poorer self-perceived performance and greater post-task state anxiety, above gender role self-discrepancies and confederate gender. For the speech task, only greater self-discrepancy in prototypical masculine traits predicted poorer performance ratings, and it was related to greater state anxiety in anticipation of the task. For HSA women, psychosocial factors may play different roles in social anxiety across social contexts.

  18. The Porter-Whitesides Discrepancy: Revisiting Odd-Even Effects in Wetting Properties of n-Alkanethiolate SAMs

    Full Text Available This review discusses the Porter-Whitesides discrepancy in wetting properties of n-alkanethiolate self-assembled monolayers (SAMs. About 25 years ago, Whitesides and coworker failed to observe any odd-even effect in wetting, however, Porter and his coworker did, albeit in select cases. Most previous studies agreed with Whitesides’ results, suggesting the absence of the odd-even effect in hydrophobicity of n-alkanethiolate SAMs. Recent reports have, however, found the odd-even effect in hydrophobicity of n-alkanethiolate SAMs on smooth substrates, indicating that hydrophobicity, and analogous interfacial properties, of n-alkanethiolate SAMs significantly depends on the properties of substrate. Unfortunately, the Whitesides and Porter papers do not report on the quality of the surfaces used. Based on recent work, we inferred that the original discrepancy between Whitesides and Porter can be attributed to the quality of the surface. Odd-even effect of SAMs in charge transport, capacitance, friction, and SAM structure are also discussed in this review to inform the general discussion. The discrepancy between Porter's group and Whitesides’ group could be due to surface roughness, morphology, oxidation, and adventitious contaminants.

    Identification of a blood-based biomarker that can detect early cognitive decline presents a significant healthcare challenge. We prepared peripheral blood mononuclear cells (PBMCs) from individuals who had a poorer than predicted performance in their delayed recall performance on the Logical Memory II Subtest of the Wechsler Memory Scale (WMS) relative to their IQ estimated by the National Adult Reading Test (NART); we described these individuals as IQ-discrepant, compared with IQ-consistent, individuals. Stimulation with Aβ + LPS increased production of TNFα to a greater extent in cells from IQ-discrepant, compared with IQ-consistent, individuals. This was associated with a shift towards glycolysis and the evidence indicates that 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase (PFKFB)3 plays a role in driving glycolysis. A similar shift towards glycolysis was observed in MDMs prepared from IQ-discrepant, compared with IQ-consistent, individuals. The important finding here is that we have established an increased sensitivity to Aβ + LPS stimulation in PBMCs from individuals that under-perform on a memory task, relative to their estimated premorbid IQ, which may be an indicator of early cognitive decline. This may be a useful tool in determining the presence of early cognitive dysfunction. Copyright © 2018 Elsevier B.V. All rights reserved.

    Discrepancies between parents and adolescents regarding parenting behaviors have been hypothesized to represent a deficit in the parent-child relationship and may represent unique risk factors for poor developmental outcomes. The current study examined the predictive utility of multiple methods for characterizing discrepancies in parents’ and adolescents’ reports of parental monitoring on youth alcohol use behaviors in order to inform future study design and predictive modeling. Data for the current study came from a prospective investigation of alcohol initiation and progression. The analyzed sample consisted of 606 adolescents (6th – 8th grade; 54% female) and their parents were surveyed at baseline, with youth followed up 12 months later. A series of hierarchical logistic regressions were performed for each monitoring-related construct examined (parental knowledge, parental control, parental solicitation, and child disclosure). The results showed that adolescents’ reports were more closely related to outcomes than parents’ reports, while greater discrepancies were frequently found to be uniquely associated with greater likelihood of alcohol use behaviors. Implications for future work incorporating parents’ and adolescents’ reports are discussed. PMID:24964878
