Presenting and discharge diagnoses of hospitalized patients may differ as a result of patient complexity, diagnostic dilemmas, or errors in clinical judgment at the time of primary assessment. When diagnoses at admission and discharge are not in agreement, this discrepancy may indicate more complex processes of care and resultant costs. It is unclear whether surrogate measures reflecting quality of care are impacted by discrepant diagnoses. To assess whether an association exists between admitting and discharge International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes and other quality markers including hospital length of stay, total cost of care, and 30-day readmission rate. This was a retrospective, cross-sectional analysis of general internal medicine patients aged 18 years and older. Diagnosis discrepancy was defined as a difference between the 3-digit ICD-9 diagnosis code at admission and the principal 3-digit ICD-9 diagnosis code at discharge. Sixty-eight percent of patients had a diagnosis discrepancy. Diagnosis discrepancy was associated with a 0.41-day increase in length of stay (P < .001), $663 increase in direct costs (P < .001), and a 1.55 times greater odds of readmission within 30 days (P < .001). Diagnosis discrepancy was associated with hospital quality outcome measures. This finding likely reflects variations in patients' diagnostic complexity.

Research suggests that masculine socialization processes contribute to the perpetration of intimate partner violence (IPV) by men. Although this research has traditionally focused on men who strongly adhere to traditional gender norms, men who negatively evaluate themselves as falling short of these norms (a construct termed masculine discrepancy stress) have proven to be at increased risk of IPV perpetration. Likewise, men experiencing problems with emotion regulation, a multidimensional construct reflecting difficulties in effectively experiencing and responding to emotional states, are also at risk of IPV perpetration. In the present research, we tested the hypothesis that the link between discrepancy stress and IPV perpetration is mediated via difficulties in emotion regulation. Three hundred fifty-seven men completed online surveys assessing their experience of discrepancy stress, emotion-regulation difficulties, and history of IPV perpetration. Results indicated that discrepancy-stressed men's use of physical IPV was fully mediated by emotion-regulation difficulties. In addition, emotion-regulation difficulties partially mediated the association between discrepancy stress and sexual IPV. Findings are discussed in terms of the potential utility of emotion-focused interventions for modifying men's experience and expression of discrepancy stress and reducing perpetration of IPV.

Discrepancy stress, stress about being perceived to not conform to one's gender role (i.e., gender role discrepancy), has demonstrated effects on risky sexual and violent behaviors. However, evidence of these effects has been limited to men and boys, neglecting the impact gender role discrepancy and discrepancy stress may have on girls. In addition, no study to date, has assessed the mental health correlates of gender role discrepancy and discrepancy stress. In the current study, we sought to elucidate the relationship between perceived feminine discrepancy and feminine discrepancy stress and psychosocial maladjustment while controlling for trauma symptoms stemming from the potential repercussions of feminine discrepancy. Maladjustment was measured by creating a second-order latent factor derived from four first-order latent constructs: sexual behavior, substance use, mood disorder symptoms, and hopelessness. Data are drawn from a cross-sectional sample of female students in middle and high school (N = 643) who completed self-report questionnaires. Using structural equation modeling, we found girls reporting feminine discrepancy (i.e., less feminine than the average girl) were more likely to report feminine discrepancy stress and trauma symptomatology. Controlling for feminine discrepancy and trauma symptoms, the relationship between discrepancy stress and maladjustment was positive and significant. Additionally, girls reporting feminine discrepancy scored higher on trauma symptomatology, and trauma demonstrated a strong direct effect on psychosocial maladjustment. These data suggest that developing trauma focused prevention strategies that incorporate social norms around gender socialization may have an impact on multiple behavioral and mental health problems.

En Route to Depression: Self-Esteem Discrepancies and Habitual Rumination.

Phillips, Wendy J; Hine, Donald W

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.

2010-11-01

Studies on cognitive aspects of science education, especially how students achieve conceptual change, have been a focus of interest for many years. Researchers of student learning and conceptual change have developed several easily applicable teaching strategies. One of these strategies is known as discrepant events. Discrepant events are very powerful ways to stimulate interest, motivate students to challenge their covert science misconceptions, and promote higher-order thinking skills. The key point is that directly challenging students' naive ideas will lead to more quality science learning going on in the classroom. In this paper, we summarize the research-based role of discrepant events in conceptual change and we share several highly successful discrepant events we use in our own classes.

2018-05-15

Correlates of receptive-expressive vocabulary size discrepancies may provide insights into why language development in children with autism spectrum disorder (ASD) deviates from typical language development and ultimately improve intervention outcomes. We indexed receptive-expressive vocabulary size discrepancies of 65 initially preverbal children with ASD (20-48 months) to a comparison sample from the MacArthur-Bates Communicative Development Inventories Wordbank (Frank, Braginsky, Yurovsky, & Marchman, 2017) to quantify typicality. We then tested whether attention toward a speaker and oral motor performance predict typicality of the discrepancy 8 months later. Attention toward a speaker correlated positively with receptive-expressive vocabulary size discrepancy typicality. Imitative and nonimitative oral motor performance were not significant predictors of vocabulary size discrepancy typicality. Secondary analyses indicated that midpoint receptive vocabulary size mediated the association between initial attention toward a speaker and end point receptive-expressive vocabulary size discrepancy typicality. Findings support the hypothesis that variation in attention toward a speaker might partially explain receptive-expressive vocabulary size discrepancy magnitude in children with ASD. Results are consistent with an input-processing deficit explanation of language impairment in this clinical population. Future studies should test whether attention toward a speaker is malleable and causally related to receptive-expressive discrepancies in children with ASD.

Research on gender roles suggests that men who strongly adhere to traditional masculine gender norms are at increased risk for the perpetration of violent and abusive acts toward their female intimate partners. Yet, gender norms alone fail to provide a comprehensive explanation of the multifaceted construct of intimate partner violence (IPV) and there is theoretical reason to suspect that men who fail to conform to masculine roles may equally be at risk for IPV. In the present study, we assessed effect of masculine discrepancy stress, a form of distress arising from perceived failure to conform to socially-prescribed masculine gender role norms, on IPV. Six-hundred men completed online surveys assessing their experience of discrepancy stress, masculine gender role norms, and history of IPV. Results indicated that masculine discrepancy stress significantly predicted men’s historical perpetration of IPV independent of other masculinity related variables. Findings are discussed in terms of potential distress engendered by masculine socialization as well as putative implications of gender role discrepancy stress for understanding and intervening in partner violence perpetrated by men.

2015-01-01

Background and aims There is increasing clinical and legal interest in discrepancies between decision-making ability and cognition in old age, a stage of life when decisions have major ramifications. We investigated the frequency and correlates of such discrepancies in non-demented older adults participating in a large community-based cohort study of aging, the Rush Memory and Aging Project. Methods Participants [n = 689, mean age 81.8 (SD 7.6), mean education 15.2 (SD 3.1), 76.8 % female and 93.3 % white] completed a measure of financial and healthcare decision making (DM) and a battery of 19 neuropsychological tests from which a composite measure of global cognition (COG) was derived. Results Results indicated that 23.9 % of the sample showed a significant discrepancy between DM and COG abilities. Of these, 12.9 % showed DM < COG, while 11.0 % showed DM > COG. Logistic regression models showed older age, being non-white, greater temporal discounting, and greater risk aversion were associated with higher odds of being in the DM < COG group. Being male was associated with higher odds of being in the DM > COG group. Education, income, depressive symptoms, and impulsivity were not associated with a discrepancy. Only demographic associations (age, sex, and race) remained significant in a fully adjusted model with terms included for all factors. Conclusion These results support the consideration of decision making and cognition as potentially separate constructs. PMID:25995167

The objective of this study was to compare cervical high-grade squamous intraepithelial lesions subcategorized as cervical intraepithelial neoplasia-3 (CIN-3)-positive after a negative cytology result but positive for high-risk human papillomavirus (HR-HPV) testing to those with a negative HR-HPV test but positive cytology (atypical squamous cells of undetermined significance [ASCUS]-positive/HPV-negative) and to assess reasons for discrepancies. The authors retrospectively analyzed women who underwent screening with cytology and HPV testing from 2010 through 2013. After a review of surgical specimens and cytology, discrepancies were classified as sampling or interpretation error. Clinical and pathologic findings were compared. In total, 15,173 women (age range, 25-95 years; 7.1% were aged < 30 years) underwent both HPV and cytologic testing, and 1184 (8.4%) underwent biopsy. Cytology was positive in 19.4% of specimens, and HPV was positive in 14.5%. Eighty-four CIN-3-positive specimens were detected, including 55 that tested ASCUS-positive/HPV-positive, 11 that tested negative for intraepithelial lesion or malignancy (NILM)/HPV-positive, 10 that tested ASCUS-positive/HPV-negative, 3 that tested NILM/HPV-negative, and 5 tests that were unsatisfactory. There was no significant difference between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3 in terms of size, time to occurrence, the presence of a cytopathic effect, screening history, race, or age. Six of 11 NILM/HPV-positive cases were reclassified as ASCUS, indicating an interpreting error of 55% and a sampling error of 45%. No ASCUS-positive/HPV-negative cases were reclassified. Seven cases of CIN-3 with positive cytology were HPV-negative. There are no significant clinical or pathologic differences between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3-positive specimens. Cytologic sampling or interpretation remains the main reason for discrepancies. However, HPV-negative CIN-3 with positive

Intraoperative pulse oximetry: frequency and distribution of discrepant data.

Pan, P H; Gravenstein, N

To determine the types of discrepant data during intraoperative pulse oximetry and their frequency and duration. Prospective study. University medical center. 46 consecutive ASA physical status I-III patients undergoing general anesthesia for elective surgical operations. With an integrated computer algorithm on the pulse oximeter and another computer linked to it, data were screened and the frequency and distribution of the following oximeter signals recorded: absent; low quality or interrupted, as detected by the pulse oximeter algorithm; nonphysiologic, identified by the personal computer as a heart rate change greater than 10 beats per minute within 2 consecutive 2-second samples, with no similar abrupt change reported simultaneously on ECG. The number of episodes per hour of discrepant oximeter data and the duration of the episodes were recorded by phase of anesthesia: induction, maintenance, and emergence. Discrepant data occurred most frequently and lasted longest during emergence (p < 0.05); the majority of episodes of discrepant data during emergence lasted less than 12 seconds. Excluding discrepant data that lasted less than 12 seconds decreased the frequency of discrepant data by 63% and excluding those that lasted less than 30 seconds decreased the frequency of discrepant data by 93%. Pulse oximeters frequently report discrepant data intraoperatively, most frequently during emergence from anesthesia. An alarm delay triggered by discrepant data and lasting 12 to 30 seconds would keep most discrepant data from becoming false alarms and, thus, may reduce distracting sound pollution in the operating room.

Huntington's disease results from a CAG repeat expansion within the Huntingtin gene; this is measured routinely in diagnostic laboratories. The European Huntington's Disease Network REGISTRY project centrally measures CAG repeat lengths on fresh samples; these were compared with the original results from 121 laboratories across 15 countries. We report on 1326 duplicate results; a discrepancy in reporting the upper allele occurred in 51% of cases, this reduced to 13.3% and 9.7% when we applied acceptable measurement errors proposed by the American College of Medical Genetics and the Draft European Best Practice Guidelines, respectively. Duplicate results were available for 1250 lower alleles; discrepancies occurred in 40% of cases. Clinically significant discrepancies occurred in 4.0% of cases with a potential unexplained misdiagnosis rate of 0.3%. There was considerable variation in the discrepancy rate among 10 of the countries participating in this study. Out of 1326 samples, 348 were re-analysed by an accredited diagnostic laboratory, based in Germany, with concordance rates of 93% and 94% for the upper and lower alleles, respectively. This became 100% if the acceptable measurement errors were applied. The central laboratory correctly reported allele sizes for six standard reference samples, blind to the known result. Our study differs from external quality assessment (EQA) schemes in that these are duplicate results obtained from a large sample of patients across the whole diagnostic range. We strongly recommend that laboratories state an error rate for their measurement on the report, participate in EQA schemes and use reference materials regularly to adjust their own internal standards.

Mother-son discrepant reporting on parenting practices: The contribution of temperament and depression.

PubMed

Shishido, Yuri; Latzman, Robert D

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.

Bolton's ratios help in estimating overbite, overjet relationships, the effects of contemplated extractions on posterior occlusion, incisor relationships and identification of occlusal misfit produced by tooth size discrepancies. To determine any difference in tooth size discrepancy in anterior as well as overall ratio in different malocclusions and comparison with Bolton's study. After measuring the teeth on all 100 patients, Bolton's analysis was performed. Results were compared with Bolton's means and standard deviations. The results were also subjected to statistical analysis. Results show that the mean and standard deviations of ideal occlusion cases are comparable with those Bolton but, when the mean and standard deviation of malocclusion groups are compared with those of Bolton, the values of standard deviation are higher, though the mean is comparable.

Parents influence urban youths’ violence-related behaviors. To provide effective guidance, parents should understand how youth perceive conflict, yet little empirical research has been conducted regarding parent and youth perceptions of conflict. The aims of this paper were to: (1) report on the nature of discrepancies in attribution of fault, (2) present qualitative data about the varying rationales for fault attribution, and (3) use quantitative data to identify correlates of discrepancy including report of attitudes towards violence, parental communication, and parents’ messages about retaliatory violence. Interviews were conducted with 101 parent/adolescent dyads. The study population consisted of African American female caretakers (n= 92; i.e., mothers, grandmothers, aunts) and fathers (n=9) and their early adolescents (mean age=13.6). A total of 53 dyads were discrepant in identifying instigators in one or both videos. When discrepancy was present, the parent was more likely to identify the actor who reacted to the situation as at fault. In the logistic regression models, parental attitudes about retaliatory violence were a significant correlate of discrepancy, such that as parent attitudes supporting retaliatory violence increased the odds of discrepancy decreased. The results suggest that parents and adolescents do not always view conflict situations similarly, which may inhibit effective parent-child communication, parental advice, and discipline. Individuals developing and implementing family-based violence prevention interventions need to be cognizant of the complexity of fault attribution and design strategies to promote conversations around attribution of fault and effective conflict management.

Understanding Yield Anomalies in ICF Implosions via Fully Kinetic Simulations

NASA Astrophysics Data System (ADS)

Taitano, William

2017-10-01

In the quest towards ICF ignition, plasma kinetic effects are among prime candidates for explaining some significant discrepancies between experimental observations and rad-hydro simulations. To assess their importance, high-fidelity fully kinetic simulations of ICF capsule implosions are needed. Owing to the extremely multi-scale nature of the problem, kinetic codes have to overcome nontrivial numerical and algorithmic challenges, and very few options are currently available. Here, we present resolutions of some long-standing yield discrepancy conundrums using a novel, LANL-developed, 1D-2V Vlasov-Fokker-Planck code iFP. iFP possesses an unprecedented fidelity and features fully implicit time-stepping, exact mass, momentum, and energy conservation, and optimal grid adaptation in phase space, all of which are critically important for ensuring long-time numerical accuracy of the implosion simulations. Specifically, we concentrate on several anomalous yield degradation instances observed in Omega campaigns, with the so-called ``Rygg effect'', or an anomalous yield scaling with the fuel composition, being a prime example. Understanding the physical mechanisms responsible for such degradations in non-ignition-grade Omega experiments is of great interest, as such experiments are often used for platform and diagnostic development, which are then used in ignition-grade experiments on NIF. In the case of Rygg's experiments, effects of a kinetic stratification of fuel ions on the yield have been previously proposed as the anomaly explanation, studied with a kinetic code FPION, and found unimportant. We have revisited this issue with iFP and obtained excellent yield-over-clean agreement with the original Rygg results, and several subsequent experiments. This validates iFP and confirms that the kinetic fuel stratification is indeed at the root of the observed yield degradation.

To evaluate the consistency of reporting of trials that are registered in the ClinicalTrials.gov results database and published in the literature. ClinicalTrials.gov results database and matched publications identified through ClinicalTrials.gov and a manual search of 2 electronic databases. 10% random sample of phase 3 or 4 trials with results in the ClinicalTrials.gov results database, completed before 1 January 2009, with 2 or more groups. One reviewer extracted data about trial design and results from the results database and matching publications. A subsample was independently verified. Of 110 trials with results, most were industry-sponsored, parallel-design drug studies. The most common inconsistency was the number of secondary outcome measures reported (80%). Sixteen trials (15%) reported the primary outcome description inconsistently, and 22 (20%) reported the primary outcome value inconsistently. Thirty-eight trials inconsistently reported the number of individuals with a serious adverse event (SAE); of these, 33 (87%) reported more SAEs in ClinicalTrials.gov. Among the 84 trials that reported SAEs in ClinicalTrials.gov, 11 publications did not mention SAEs, 5 reported them as zero or not occurring, and 21 reported a different number of SAEs. Among 29 trials that reported deaths in ClinicalTrials.gov, 28% differed from the matched publication. Small sample that included earliest results posted to the database. Reporting discrepancies between the ClinicalTrials.gov results database and matching publications are common. Which source contains the more accurate account of results is unclear, although ClinicalTrials.gov may provide a more comprehensive description of adverse events than the publication.

The apsidal motion of the eccentric eclipsing binary DI Herculis (HD 175227) is determined from an analysis of the available observations and eclipse timings from 1959 to 1984. Least squares solutions to the primary and secondary minima extending over an 84-yr interval yielded a small advance of periastron omega dot of 0.65 deg/100 yr + or - 0.18/100 yr. The observed advance of the periastron is about one seventh of the theoretical value of 4.27 deg/100 yr that is expected from the combined relativistic and classical effects. The discrepancy is about -3.62 deg/100 yr, or a magnitude of about 20 sigma. Classical mechanisms which explain the discrepancy are discussed, together with the possibility that there may be problems with general relativity itself.

Medication discrepancies are defined as unexplained differences among regimens across different sites of care. The problem of medication discrepancies that occur during the entire care pathway from hospital admission to a local care setting discharge (namely all types of settings dedicated to formal care other than hospitals) has received little attention in the medical literature. The present study aims to (1) determine the prevalence of medication discrepancies that occur during the entire care pathway from hospital admission to local care setting discharge, (2) describe the discrepancy and medication type, and (3) identify potential risk factors for experiencing medication discrepancies in patient care transitions. Evidence from an integrated health care system, such as the Italian one, may explain results from other studies in different healthcare systems. A retrospective longitudinal cohort study of patients admitted from July 2015 to July 2016 to the Giovanni Bosco Hospital serving Turin, Italy and its surrounding territory was performed. Discrepancies were recorded at the following four care transitions: T1: Hospital admission; T2: Hospital discharge; T3: Admission into local care settings; T4: Discharge from local care settings. All evaluations were based on documented regimens and were performed by a team (doctor, nurse and pharmacists). Of 366 included patients, 25.68% had at least one discrepancy. The most frequent type of discrepancy was from medication omission (N = 74; 71.15%). Only discharge from a long-stay care setting (T4) was significantly associated with the onset of discrepancies (p = 0.045). When considering a lack of adequate documentation, not as missing data but as a discrepancy, 43.72% of patients had at least one discrepancy. This study suggests that an integrated health care system, such as Italian system, may influence the prevalence of discrepancies, thus highlighting the need for structured multidisciplinary and, if possible

ABSTRACT Regards and Tribute: Late Dr Narender Hasija was a mentor and visionary in the light of knowledge and experience. We pay our regards with deepest gratitude to the departed soul to rest in peace. Bolton’s ratios help in estimating overbite, overjet relationships, the effects of contemplated extractions on posterior occlusion, incisor relationships and identification of occlusal misfit produced by tooth size discrepancies. Aim: To determine any difference in tooth size discrepancy in anterior as well as overall ratio in different malocclusions and comparison with Bolton’s study. Materials and methods: After measuring the teeth on all 100 patients, Bolton’s analysis was performed. Results were compared with Bolton’s means and standard deviations. The results were also subjected to statistical analysis. Results show that the mean and standard deviations of ideal occlusion cases are comparable with those Bolton but, when the mean and standard deviation of malocclusion groups are compared with those of Bolton, the values of standard deviation are higher, though the mean is comparable.

Large electroweak penguin contribution in B{yields}K{pi} and {pi}{pi} decay modes

2004-11-01

We discuss a possibility of large electroweak penguin contribution in B{yields}K{pi} and {pi}{pi} from recent experimental data. The experimental data may be suggesting that there are some discrepancies between the data and theoretical estimation in the branching ratios of them. In B{yields}K{pi} decays, to explain it, a large electroweak penguin contribution and large strong phase differences seem to be needed. The contributions should appear also in B{yields}{pi}{pi}. We show, as an example, a solution to solve the discrepancies in both B{yields}K{pi} and B{yields}{pi}{pi}. However the magnitude of the parameters and the strong phase estimated from experimental data are quite largemore » compared with the theoretical estimations. It may be suggesting some new physics effects are included in these processes. We will have to discuss about the dependence of the new physics. To explain both modes at once, we may need large electroweak penguin contribution with new weak phases and some SU(3) breaking effects by new physics in both QCD and electroweak penguin-type processes.« less

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

PubMed

Brown, Christina M; McConnell, Allen R

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.

To assess the association between maternal and fetal characteristics and discrepancy between last normal menstrual period and early (<20 weeks) ultrasound-based gestational age and the association between discrepancies and pregnancy outcomes. Hospital-based cohort study. Montreal, Canada. A total of 46,514 women with both menstrual- and early ultrasound-based gestational age estimates. Positive (last normal menstrual period > early ultrasound, i.e. menstrual-based gestational age is higher than early ultrasound-based gestational age, so that the expected date of delivery is earlier with the menstrual-based gestational age) discrepancies > or =+7 days, mean birthweight, low birthweight, stillbirth and in-hospital neonatal death. Multiparous mothers and those with diabetes, small stature or high pre-pregnancy body mass index were more likely to have positive discrepancies. The proportion of women with discrepancies > or =+7 days was significantly higher among chromosomally malformed and female fetuses. The mean birthweight declined with increasingly positive differences. The risk of low birthweight was significantly higher for positive differences. Associations with fetal growth measures were more plausible with early ultrasound estimates. Although most discrepancies between last normal menstrual period- and early ultrasound-based gestational age are attributable to errors in menstrual dating, our results suggest that some positive differences reflect early growth restriction.

This work presents the Australian Clinical Dosimetry Service's (ACDS) findings of an investigation of systematic discrepancies between treatment planning system (TPS) calculated and measured audit doses. Specifically, a comparison between the Anisotropic Analytic Algorithm (AAA) and other common dose-calculation algorithms in regions downstream (≥2cm) from low-density material in anthropomorphic and slab phantom geometries is presented. Two measurement setups involving rectilinear slab-phantoms (ACDS Level II audit) and anthropomorphic geometries (ACDS Level III audit) were used in conjunction with ion chamber (planar 2D array and Farmer-type) measurements. Measured doses were compared to calculated doses for a variety of cases, with and without the presence of inhomogeneities and beam-modifiers in 71 audits. Results demonstrate a systematic AAA underdose with an average discrepancy of 2.9 ± 1.2% when the AAA algorithm is implemented in regions distal from lung-tissue interfaces, when lateral beams are used with anthropomorphic phantoms. This systemic discrepancy was found for all Level III audits of facilities using the AAA algorithm. This discrepancy is not seen when identical measurements are compared for other common dose-calculation algorithms (average discrepancy -0.4 ± 1.7%), including the Acuros XB algorithm also available with the Eclipse TPS. For slab phantom geometries (Level II audits), with similar measurement points downstream from inhomogeneities this discrepancy is also not seen. Crown Copyright © 2015. Published by Elsevier Ltd.

Gender Role Discrepancy Stress, High-Risk Sexual Behavior, and Sexually Transmitted Disease.

2016-02-01

Nearly 20 million new sexually transmitted infections occur every year in the United States. Traditionally, men have demonstrated much greater risk for contraction of and mortality from STDs perhaps because they tend to engage in a number of risky sexual activities. Research on masculinity suggests that gender roles influence males' sexual health by encouraging risk-taking behavior, discouraging access to health services, and narrowly defining their roles as partners. However, despite the propensity of highly masculine men to engage in high-risk sexual behavior, there is reason to suspect that men at the other end of the continuum may still be driven to engage in similar high-risk behaviors as a consequence of gender socialization. Discrepancy stress is a form of gender role stress that occurs when men fail to live up to the ideal manhood derived from societal prescriptions (i.e., Gender Role Discrepancy). In the present study, we surveyed a national sample of 600 men via Amazon Mechanical Turk to assess perceived gender role discrepancy, experience of discrepancy stress, and the associations with risky sexual behavior and potential contraction of STDs. Results indicated that men who believe they are less masculine than the typical man (i.e., gender role discrepancy) and experience distress stemming from this discrepancy (i.e., discrepancy stress) engage in high-risk sexual behavior and are subsequently diagnosed with more STDs. Findings are discussed in relation to implications for primary prevention strategies.

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.

An extensive body of research has explored the effects of parental monitoring on adolescent outcomes, but studies consistently find substantial discrepancies between parent and adolescent reports of different monitoring behaviors. Little research has examined whether parents and adolescents are more or less discrepant when reporting on parents' rules or solicitation for different adolescent problem and health risk behaviors and few studies have explored potential explanatory variables to explicate individual variability in parent-adolescent discrepant reporting. To address this gap in the literature, the current study examined discrepancies in mother-adolescent reports of family rules and solicitation across five distinct adolescent behaviors: personal behaviors and four different risk behaviors (alcohol-related, cyber, over- and under-eating). Participants were 143 mother-adolescent dyads (Adolescent M age  = 14.42, SD = 1.73, range = 12-18, 81 % white, 60 % female). Mean-level discrepancies between maternal and adolescent reports significantly differed by category of adolescent behavior and also varied as a function of reported parental monitoring behavior (rules vs. solicitation). Discrepancies in mother-adolescent reports of behavior-specific rules and solicitation were positively associated with discrepancies in mother and adolescent judgments of the harmfulness of the activities. The results demonstrate that discrepancies in mother-adolescent reports of family process differ by category of adolescent behavior and may be undergirded by differences in mother and adolescent informational assumptions about the potential harm involved with different activities.

An atlas-based multimodal registration method for 2-dimension images with discrepancy structures was proposed in this paper. Atlas was utilized for complementing the discrepancy structure information in multimodal medical images. The scheme includes three steps: floating image to atlas registration, atlas to reference image registration, and field-based deformation. To evaluate the performance, a frame model, a brain model, and clinical images were employed in registration experiments. We measured the registration performance by the squared sum of intensity differences. Results indicate that this method is robust and performs better than the direct registration for multimodal images with discrepancy structures. We conclude that the proposed method is suitable for multimodal images with discrepancy structures. Graphical Abstract An Atlas-based multimodal registration method schematic diagram.

Abstract Aim: The purpose of the study was to assess the marginal adaptation and discrepancy of SSC’s. Differences in adaptation and discrepancy between the four surfaces (mesial, lingual, distal, and buccal) were evaluated. Methods: The placement of stainless steel crowns were completed on a phantom head in accordance with the clinical technique. The ideal tooth preparation was made and this ‘master tooth’ duplicated to achieve a sample size of 15. The stainless steel crowns were placed, trimmed, and cemented as per the clinical technique. The cemented stainless crowns were analyzed under 100× stereomicroscope magnification. The marginal adaptation and discrepancy of each specimen was measured every 2 µm. Results: All the specimens showed marginal adaptation and discrepancy. The lingual margin had a significantly better adaptation (p < .0001) over the other surfaces. The buccal surface was the only surface that had an appropriate supra-CEJ level with a significance of p < .0001. Conclusion: The marginal discrepancies occur during the trimming procedure and assessment of the gingival approximation of the SSC margin. The inspection of stainless steel crown adaptation and discrepancy is an essential clinical step. PMID:29536024

The ED at Catawba Valley Medical Center in Hickory, NC, has improved its responses to radiology discrepancies by redesigning its process and giving ownership of that process to two nurses. Here are some of the key aspects of the process: every day the coordinators check the computer system, into which discrepancies are entered by radiology. Diagnosis and treatment are reviewed with one of the ED physicians. If the patient has been discharged, the coordinator will contact the patient via phone or follow-up letter.

To determine whether specific design interventions (changes in the user interface (UI)) of an electronic health record (EHR) medication module are associated with an increase or decrease in the incidence of contradictions between the structured and narrative components of electronic prescriptions (internal prescription discrepancies). We performed a retrospective analysis of 960,000 randomly selected electronic prescriptions generated in a single EHR between 01/2004 and 12/2011. Internal prescription discrepancies were identified using a validated natural language processing tool with recall of 76% and precision of 84%. A multivariable autoregressive integrated moving average (ARIMA) model was used to evaluate the effect of five UI changes in the EHR medication module on incidence of internal prescription discrepancies. Over the study period 175,725 (18.4%) prescriptions were found to have internal discrepancies. The highest rate of prescription discrepancies was observed in March 2006 (22.5%) and the lowest in March 2009 (15.0%). Addition of "as directed" option to the dropdown decreased prescription discrepancies by 195 / month (p = 0.0004). An non-interruptive alert that reminded providers to ensure that structured and narrative components did not contradict each other decreased prescription discrepancies by 145 / month (p = 0.03). Addition of a "Renew / Sign" button to the Medication module (a negative control) did not have an effect in prescription discrepancies. Several UI changes in the electronic medication module were effective in reducing the incidence of internal prescription discrepancies. Further research is needed to identify interventions that can completely eliminate this type of prescription error and their effects on patient outcomes.

Discrepancy Between ASTER- and MODIS- Derived Land Surface Temperatures: Terrain Effects

2009-01-01

The MODerate resolution Imaging Spectroradiometer (MODIS) and the Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) are onboard the same satellite platform NASA TERRA. Both MODIS and ASTER offer routine retrieval of land surface temperatures (LSTs), and the ASTER- and MODIS-retrieved LST products have been used worldwide. Because a large fraction of the earth surface consists of mountainous areas, variations in elevation, terrain slope and aspect angles can cause biases in the retrieved LSTs. However, terrain-induced effects are generally neglected in most satellite retrievals, which may generate discrepancy between ASTER and MODIS LSTs. In this paper, we reported the terrain effects on the LST discrepancy with a case examination over a relief area at the Loess Plateau of China. Results showed that the terrain-induced effects were not major, but nevertheless important for the total LST discrepancy. A large local slope did not necessarily lead to a large LST discrepancy. The angle of emitted radiance was more important than the angle of local slope in generating the LST discrepancy. Specifically, the conventional terrain correction may be unsuitable for densely vegetated areas. The distribution of ASTER-to-MODIS emissivity suggested that the terrain correction was included in the generalized split window (GSW) based approach used to rectify MODIS LSTs. Further study should include the classification-induced uncertainty in emissivity for reliable use of satellite-retrieved LSTs over relief areas. PMID:22399955

Discrepancy and Disliking Do Not Induce Negative Opinion Shifts

PubMed Central

Flache, Andreas; Mäs, Michael

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. PMID:27333160

Recent work on dating Copernican-aged craters, using Lunar Reconnaissance Orbiter (LRO) Camera data, re-encountered a curious discrepancy in crater size-frequency distribution (CSFD) measurements that was observed, but not understood, during the Apollo era. For example, at Tycho, Copernicus, and Aristarchus craters, CSFDs of impact melt deposits give significantly younger relative and absolute model ages (AMAs) than impact ejecta blankets, although these two units formed during one impact event, and would ideally yield coeval ages at the resolution of the CSFD technique. We investigated the effects of contrasting target properties on CSFDs and their resultant relative and absolute model ages for coeval lunar impact melt and ejecta units. We counted craters with diameters through the transition from strength- to gravity-scaling on two large impact melt deposits at Tycho and King craters, and we used pi-group scaling calculations to model the effects of differing target properties on final crater diameters for five different theoretical lunar targets. The new CSFD for the large King Crater melt pond bridges the gap between the discrepant CSFDs within a single geologic unit. Thus, the observed trends in the impact melt CSFDs support the occurrence of target property effects, rather than self-secondary and/or field secondary contamination. The CSFDs generated from the pi-group scaling calculations show that targets with higher density and effective strength yield smaller crater diameters than weaker targets, such that the relative ages of the former are lower relative to the latter. Consequently, coeval impact melt and ejecta units will have discrepant apparent ages. Target property differences also affect the resulting slope of the CSFD, with stronger targets exhibiting shallower slopes, so that the final crater diameters may differ more greatly at smaller diameters. Besides their application to age dating, the CSFDs may provide additional information about the

False consensus and adolescent peer contagion: examining discrepancies between perceptions and actual reported levels of friends' deviant and health risk behaviors.

Adolescents' perceptions of their friends' behavior strongly predict adolescents' own behavior, however, these perceptions often are erroneous. This study examined correlates of discrepancies between adolescents' perceptions and friends' reports of behavior. A total of 120 11th-grade adolescents provided data regarding their engagement in deviant and health risk behaviors, as well as their perceptions of the behavior of their best friend, as identified through sociometric assessment. Data from friends' own report were used to calculate discrepancy measures of adolescents' overestimations and estimation errors (absolute value of discrepancies) of friends' behavior. Adolescents also completed a measure of friendship quality, and a sociometric assessment yielding measures of peer acceptance/rejection and aggression. Findings revealed that adolescents' peer rejection and aggression were associated with greater overestimations of friends' behavior. This effect was partially mediated by adolescents' own behavior, consistent with a false consensus effect. Low levels of positive friendship quality were significantly associated with estimation errors, but not overestimations specifically.

A newly identified calculation discrepancy of the Sunset semi-continuous carbon analyzer

Zheng, G.; Cheng, Y.; He, K.; Duan, F.; Ma, Y.

2014-01-01

Sunset Semi-Continuous Carbon Analyzer (SCCA) is an instrument widely used for carbonaceous aerosol measurement. Despite previous validation work, here we identified a new type of SCCA calculation discrepancy caused by the default multi-point baseline correction method. When exceeding a certain threshold carbon load, multi-point correction could cause significant Total Carbon (TC) underestimation. This calculation discrepancy was characterized for both sucrose and ambient samples with three temperature protocols. For ambient samples, 22%, 36% and 12% TC was underestimated by the three protocols, respectively, with corresponding threshold being ~0, 20 and 25 μg C. For sucrose, however, such discrepancy was observed with only one of these protocols, indicating the need of more refractory SCCA calibration substance. The discrepancy was less significant for the NIOSH (National Institute for Occupational Safety and Health)-like protocol compared with the other two protocols based on IMPROVE (Interagency Monitoring of PROtected Visual Environments). Although the calculation discrepancy could be largely reduced by the single-point baseline correction method, the instrumental blanks of single-point method were higher. Proposed correction method was to use multi-point corrected data when below the determined threshold, while use single-point results when beyond that threshold. The effectiveness of this correction method was supported by correlation with optical data.

Background Healthcare institutions are often faced with challenges and accreditation requirements for improving treatment quality, reducing waste, and avoiding diversion of drugs, particularly controlled substances. Many automated systems have replaced manual systems but may be fraught with challenges, especially when multiple users are involved. Objective To describe the characteristics of controlled substance discrepancies observed in a Level I trauma hospital for Medicare. Methods Discrepancy data were captured for each user involved in a transaction for a controlled substance at the Level I trauma hospital (in Ben Taub Hospital, Houston, TX), and the information was stored in a computerized database repository. Data for the 1-year study period (from January 1 through December 31, 2013) were collected for Medicare beneficiaries, using an Excel 2013 spreadsheet, and were analyzed according to basic discrepancy characteristics and descriptive statistics. Results During the 12-month study period, 114,000 controlled substance discrepancies were found for 100,000 Medicare patients at this Level I trauma hospital. Vending activities accounted for the majority (52.6%) of these discrepancies. Discrepancies were most likely to occur on Wednesdays, and the medications involved most frequently were combination drugs of hydrocodone and acetaminophen. Conclusion Approximately 1 (1.14) discrepancy involving a controlled substance occurred for each Medicare patient treated at the study facility. Healthcare institutions need to improve their efforts to ensure high-quality care and prevent diversion of drugs. PMID:27606038

Shared temporoparietal dysfunction in dyslexia and typical readers with discrepantly high IQ.

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.

Tooth-size discrepancy: A comparison between manual and digital methods

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.

First, to investigate the prevalence and types of drug therapy problems and medication discrepancies among super-utilizers, and associated patient characteristics. Second, to examine the outcomes of pharmacist recommendations and estimated cost avoidance through care transitions support focused on medication management. Retrospective analysis of the pharmacist-led interventions as part of the SafeMed Program. A large nonprofit health care system serving the major medically underserved areas in Memphis, Tennessee. Three hundred seventy-four super-utilizing SafeMed participants with multiple chronic conditions and polypharmacy. Comprehensive medication review, medication therapy management, enhanced discharge planning, home visits, telephone follow-up, postdischarge medication reconciliation, and care coordination with physicians. Types of drug therapy problems, outcomes of pharmacist recommendations, estimated cost avoided, medication discrepancies, and self-reported medication adherence. Prevalence of drug therapy problems and postdischarge medication discrepancies was 80.7% and 75.4%, respectively. The most frequently occurring drug therapy problems were enrollee not receiving needed medications (33.4%), underuse of medications (16.9%), and insufficient dose or duration (11.2%). Overall 50.8% of the pharmacist recommendations were accepted by physicians and patients, resulting in an estimated cost avoidance of $293.30 per drug therapy problem identified. Multivariate analysis indicated that participants with a higher number of comorbidities were more likely to have medication discrepancies (odds ratio 1.23 [95% CI 1.05-1.44]). Additional contributors to postdischarge medication discrepancies were difficulty picking up and paying for medications and not being given necessary prescriptions before discharge. Drug therapy problems and medication discrepancies are common in super-utilizers with multiple chronic conditions and polypharmacy during transitions of care

Parent-adolescent discrepancies in family functioning play an important role in HIV risk behaviors among adolescents, yet longitudinal research with recent immigrant Hispanic families remains limited. This study tested the effects of trajectories of parent-adolescent family functioning discrepancies on HIV risk behaviors among recent-immigrant Hispanic adolescents. Additionally, we examined whether and to what extent trajectories of parent-adolescent family functioning discrepancies vary as a function of gender. We assessed family functioning of 302 Hispanic adolescents (47 % female) and their parent (70 % female) at six time points over a three-year period and computed latent discrepancy scores between parent and adolescent reports at each timepoint. Additionally, adolescents completed measures of sexual risk behaviors and alcohol use. We conducted a confirmatory factor analysis to determine the feasibility of collapsing parent and adolescent reported family functioning indicators onto a single latent discrepancy variable, tested model invariance over time, and conducted growth mixture modeling (GMM). GMM yielded a three-class solution for discrepancies: High-Increasing, High-Stable, and Low-Stable. Relative to the Low-Stable class, parent-adolescent dyads in the High-Increasing and High-Stable classes were at greater risk for adolescents reporting sexual debut at time 6. Additionally, the High-Stable class was at greater risk, relative to the Low-Stable class, in terms of adolescent lifetime alcohol use at 30 months post-baseline. Multiple group GMM indicated that trajectories of parent-adolescent family functioning trajectories did not vary by gender. Implications for future research and practice are discussed.

Objective To examine the relationship of mother-father informant discrepancies regarding diabetes management to diabetes-specific family conflict and glycemic control. Methods 136 mothers and fathers of youth with type 1 diabetes reported on the youth's diabetes management, diabetes-specific family conflict, and amount of paternal involvement in diabetes care. Glycosylated hemoglobin A1c (HbA1c) was used to measure glycemic control. Results As hypothesized, mother-father discrepancies regarding diabetes management were positively associated with frequency of diabetes-specific family conflict. Contrary to hypotheses, mother-father discrepancies regarding diabetes management predicted poorer glycemic control for youth with less involved fathers only. Conclusions Results highlight the importance of caregivers being consistent about pediatric illness management and support the idea that informant discrepancies represent an important window into the functioning of the family system.

Impact of a pharmacy technician-centered medication reconciliation program on medication discrepancies and implementation of recommendations

PubMed Central

2016-01-01

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.

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.

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. PMID:28839415

The purpose of this study was to test the validity of dynamic leg length discrepancy (DLLD) during gait as a radiation-free screening method for measuring anatomic leg length discrepancy (ALLD). Thirty-three subjects with mild leg length discrepancy walked along a walkway and the dynamic leg length discrepancy (DLLD) was calculated using a motion analysis system. Pearson correlation and paired Student t -tests were applied to calculate the correlation and compare the differences between DLLD and ALLD (α = 0.05). The results of our study showed DLLD is not a valid method to predict ALLD in subjects with mild limb discrepancy.

The Attitude-Behavior Discrepancy in Medical Decision Making

2014-01-01

Background: In medical practice, the dissatisfaction of patients about medical decisions made by doctors is often regarded as the fuse of doctor-patient conflict. However, a few studies have looked at why there are such dissatisfactions. Objectives: This experimental study aimed to explore the discrepancy between attitude and behavior within medical situations and its interaction with framing description. Patients and Methods: A total of 450 clinical undergraduates were randomly assigned to six groups and investigated using the classic medical decision making problem, which was described either in a positive or a negative frame (2) × decision making behavior\\attitude to risky plan\\attitude to conservative plan (3). Results: A discrepancy between attitude and behavior did exist in medical situations. Regarding medical dilemmas, if the mortality rate was described, subjects had a significant tendency to choose a conservative plan (t = 3.55, P < 0.01) yet if the survival rate was described, there was no such preference (t = -1.48, P > 0.05). However, regardless of the plan chosen by the doctor, the subjects had a significant opposing attitude (P < .05). Framing description had a significant impact on both decision making behavior and attitude (t behavior = -3.24, P < 0.01；t attitude to surgery = 4.08，P < 0.01；t attitude to radiation = -2.15，P < 0.05). Conclusions: A discrepancy of attitude-behavior does exist in medical situations. The framing of a description has an impact on medical decision-making. PMID:25763230

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.

Yield Hardening of Electrorheological Fluids in Channel Flow

2016-06-01

Electrorheological fluids offer potential for developing rapidly actuated hydraulic devices where shear forces or pressure-driven flow are present. In this study, the Bingham yield stress of electrorheological fluids with different particle volume fractions is investigated experimentally in wall-driven and pressure-driven flow modes using measurements in a parallel-plate rheometer and a microfluidic channel, respectively. A modified Krieger-Dougherty model can be used to describe the effects of the particle volume fraction on the yield stress and is in good agreement with the viscometric data. However, significant yield hardening in pressure-driven channel flow is observed and attributed to an increase and eventual saturation of the particle volume fraction in the channel. A phenomenological physical model linking the densification and consequent microstructure to the ratio of the particle aggregation time scale compared to the convective time scale is presented and used to predict the enhancement in yield stress in channel flow, enabling us to reconcile discrepancies in the literature between wall-driven and pressure-driven flows.

Body self-discrepancies and women's social physique anxiety: the moderating role of the feared body.

Woodman, Tim; Steer, Rebecca

2011-05-01

We explored ideal, ought, and feared body image self-discrepancies as predictors of social physique anxiety within Carver, Lawrence, and Scheier's and Woodman and Hemmings' interaction frameworks. One hundred women completed actual, ideal, ought, and feared body self-discrepancy visual analogue scales, the Social Physique Anxiety Scale and the Beck Depression Inventory-II. Moderated hierarchical regression analyses indicated that the relationship between ought body fat discrepancies and social physique anxiety was moderated by proximity to the feared fat self. Specifically, the positive relationship between ought fat discrepancies and social physique anxiety was stronger when women were far from their feared body self. The results highlight the importance of considering the feared self in order to more fully understand the relationship between body image and social physique anxiety. ©2010 The British Psychological Society.

2017-07-01

Formal nutrition training in medical schools and residencies is lacking and needed. Registered dietitians (RDs) are formally trained in nutrition support and considered experts in the nutrition field. Our purpose was to examine prescribing and recommending discrepancies of parenteral nutrition macronutrients between medical residents (MRs) and RDs and compare results with the ASPEN clinical care guidelines. We also looked at discrepancies among obese patients, due to their increased risk of mortality. The primary end point of this retrospective review was discrepancies in nonprotein calories (NPCs) and grams of protein (PRO) between MRs and RDs. The secondary end point was discrepancies in NPCs and PRO between MRs and RDs among patients stratified by body mass index category. MRs prescribed 300 NPCs more versus RDs ( P < .001). When compared with RDs, MRs prescribed fewer NPCs for underweight patients and more for obese patients ( P < .001). The same analysis found that the PRO discrepancies significantly varied by body mass index classification as well ( P = .022). When these results were compared with the ASPEN clinical care guidelines, RDs adhered closer to the guidelines than did MRs in terms of permissive underfeeding of obese patients. It is widely accepted that MRs are in need of increased formal training, and the results of our study confirm this need and suggest a short-term solution of increasing order-writing privileges for the RD. RDs with this privilege may adhere more closely to clinical care guidelines and therefore increase patient safety.

The proceedings handbook of abstracts from scientific meetings aims to provide meeting attendees with an accurate summary of scientific presentations. Given that posters are prepared closer to the meeting than the abstracts for the proceedings book, we hypothesized that there is a high rate of inconsistency between abstracts in the proceedings handbook and the corresponding posters. We compared the poster abstracts printed in the proceedings handbook with the actual posters at the 71st annual meeting of the American Academy of Orthopaedic Surgeons in 2004. Our comparison included all 50 trauma posters and 52 adult reconstruction knee posters. This comparison revealed discrepancies in 76% of the presented posters. These changes were detected in all parts of the posters including titles (33%), authorship (49%), methods (8%), results (30%), and conclusions (2%). The sample size changed in 15% of the studies. Discrepancies between the trauma posters versus the adult reconstruction knee posters were similar. Our findings suggest that discrepancies between the poster abstracts in the proceedings handbook and actual poster presentations are common, but changes in conclusions are rare. Meeting attendees should not assume that the proceedings handbook provides an accurate reflection of poster presentations. Visiting the poster section is recommended.

Medication Reconciliation leads to quick detection of drug-related problems, studies in ambulatory care are scarce. The recently introduced Medication Plan in Germany serves as an ideal basis for Medication Reconciliation. The study aim was to provide accurate data on the magnitude of discrepancy between the prescription and the actually taken medicine. Clinical relevance of discrepancies was assessed to estimate the impact on medication safety. Patients were assessed at home, data was reconciled with the physician's documentation. Discrepancies were analyzed and stratified. Risk for hospitalization, risk for falls and the potential for drug-drug interactions was estimated based on literature. Drugs were tested for its origin and grouped to indication clusters. Detected DRPs at a Medication Review were linked to the results at Medication Reconciliation. Medication of 142 elderly patients from 12 practices was reconciled. 1498 drugs were found at the home assessment, 1099 (73.4%) of which were detected in the physician's documentation. 94.4% of the patients were affected by discrepancies. A total of 2.8 ± 2.4 drugs was undocumented per patient. 26.6% of missing drugs were prescribed by medical specialists, 42.5% of drugs of unknown origin were prescription drugs. 53.9% of the patients used a undocumented drug, which carried a high risk for hospitalization. 23.1% of the drugs not covered were used for treatment of cardiovascular diseases. 65.8% of the differing drugs caused at least one DRP. A high discrepancy between the drugs used by the patient and the medication documented by the primary care physician could be found. Relating drugs had a profound systemic effect and were particular relevant to medication safety. Many drugs were prescription drugs. The majority of differing drugs caused DRPs. A collaborative Medication Reconciliation as part of a Medication Management could compile the entire medication and increase patient safety. Copyright © 2017 Elsevier Inc

Discrepancies in medication entries between anesthetic and pharmacy records using electronic databases.

Vigoda, Michael M; Gencorelli, Frank J; Lubarsky, David A

2007-10-01

Accurate recording of disposition of controlled substances is required by regulatory agencies. Linking anesthesia information management systems (AIMS) with medication dispensing systems may facilitate automated reconciliation of medication discrepancies. In this retrospective investigation at a large academic hospital, we reviewed 11,603 cases (spanning an 8-mo period) comparing records of medications (i.e., narcotics, benzodiazepines, ketamine, and thiopental) recorded as removed from our automated medication dispensing system with medications recorded as administered in our AIMS. In 15% of cases, we found discrepancies between dispensed versus administered medications. Discrepancies occurred in both the AIMS (8% cases) and the medication dispensing system (10% cases). Although there were many different types of user errors, nearly 75% of them resulted from either an error in the amount of drug waste documented in the medication dispensing system (35%); or an error in documenting the medication in the AIMS (40%). A significant percentage of cases contained data entry errors in both the automated dispensing and AIMS. This error rate limits the current practicality of automating the necessary reconciliation. An electronic interface between an AIMS and a medication dispensing system could alert users of medication entry errors prior to finalizing a case, thus reducing the time (and cost) of reconciling discrepancies.

A newly identified calculation discrepancy of the Sunset semi-continuous carbon analyzer

2014-07-01

The Sunset semi-continuous carbon analyzer (SCCA) is an instrument widely used for carbonaceous aerosol measurement. Despite previous validation work, in this study we identified a new type of SCCA calculation discrepancy caused by the default multipoint baseline correction method. When exceeding a certain threshold carbon load, multipoint correction could cause significant total carbon (TC) underestimation. This calculation discrepancy was characterized for both sucrose and ambient samples, with two protocols based on IMPROVE (Interagency Monitoring of PROtected Visual Environments) (i.e., IMPshort and IMPlong) and one NIOSH (National Institute for Occupational Safety and Health)-like protocol (rtNIOSH). For ambient samples, the IMPshort, IMPlong and rtNIOSH protocol underestimated 22, 36 and 12% of TC, respectively, with the corresponding threshold being ~ 0, 20 and 25 μgC. For sucrose, however, such discrepancy was observed only with the IMPshort protocol, indicating the need of more refractory SCCA calibration substance. Although the calculation discrepancy could be largely reduced by the single-point baseline correction method, the instrumental blanks of single-point method were higher. The correction method proposed was to use multipoint-corrected data when below the determined threshold, and use single-point results when beyond that threshold. The effectiveness of this correction method was supported by correlation with optical data.

Local linear regression for function learning: an analysis based on sample discrepancy.

PubMed

Cervellera, Cristiano; Macciò, Danilo

2014-11-01

Local linear regression models, a kind of nonparametric structures that locally perform a linear estimation of the target function, are analyzed in the context of empirical risk minimization (ERM) for function learning. The analysis is carried out with emphasis on geometric properties of the available data. In particular, the discrepancy of the observation points used both to build the local regression models and compute the empirical risk is considered. This allows to treat indifferently the case in which the samples come from a random external source and the one in which the input space can be freely explored. Both consistency of the ERM procedure and approximating capabilities of the estimator are analyzed, proving conditions to ensure convergence. Since the theoretical analysis shows that the estimation improves as the discrepancy of the observation points becomes smaller, low-discrepancy sequences, a family of sampling methods commonly employed for efficient numerical integration, are also analyzed. Simulation results involving two different examples of function learning are provided.

Algorithms in Discrepancy Theory and Lattices

NASA Astrophysics Data System (ADS)

Ramadas, Harishchandra

This thesis deals with algorithmic problems in discrepancy theory and lattices, and is based on two projects I worked on while at the University of Washington in Seattle. A brief overview is provided in Chapter 1 (Introduction). Chapter 2 covers joint work with Avi Levy and Thomas Rothvoss in the field of discrepancy minimization. A well-known theorem of Spencer shows that any set system with n sets over n elements admits a coloring of discrepancy O(√n). While the original proof was non-constructive, recent progress brought polynomial time algorithms by Bansal, Lovett and Meka, and Rothvoss. All those algorithms are randomized, even though Bansal's algorithm admitted a complicated derandomization. We propose an elegant deterministic polynomial time algorithm that is inspired by Lovett-Meka as well as the Multiplicative Weight Update method. The algorithm iteratively updates a fractional coloring while controlling the exponential weights that are assigned to the set constraints. A conjecture by Meka suggests that Spencer's bound can be generalized to symmetric matrices. We prove that n x n matrices that are block diagonal with block size q admit a coloring of discrepancy O(√n . √log(q)). Bansal, Dadush and Garg recently gave a randomized algorithm to find a vector x with entries in {-1,1} with ∥Ax∥infinity ≤ O(√log n) in polynomial time, where A is any matrix whose columns have length at most 1. We show that our method can be used to deterministically obtain such a vector. In Chapter 3, we discuss a result in the broad area of lattices and integer optimization, in joint work with Rebecca Hoberg, Thomas Rothvoss and Xin Yang. The number balancing (NBP) problem is the following: given real numbers a1,...,an in [0,1], find two disjoint subsets I1,I2 of [ n] so that the difference |sumi∈I1a i - sumi∈I2ai| of their sums is minimized. An application of the pigeonhole principle shows that there is always a solution where the difference is at most O √n/2

Whole season compared to growth-stage resolved temperature trends: implications for US maize yield

NASA Astrophysics Data System (ADS)

Butler, E. E.; Mueller, N. D.; Huybers, P. J.

2014-12-01

The effect of temperature on maize yield has generally been considered using a single value for the entire growing season. We compare the effect of temperature trends on yield between two distinct models: a single temperature sensitivity for the whole season and a variable sensitivity across four distinct agronomic development stages. The more resolved variable-sensitivity model indicates roughly a factor of two greater influence of temperature on yield than that implied by the single-sensitivity model. The largest discrepancies occur in silking, which is demonstrated to be the most sensitive stage in the variable-sensitivity model. For instance, whereas median yields are observed to be only 53% of typical values during the hottest 1% of silking-stage temperatures, the single-sensitivity model over predicts median yields of 68% whereas the variable-sensitivity model more correctly predicts median yields of 61%. That the variable sensitivity model is also not capable of capturing the full extent of yield losses suggests that further refinement to represent the non-linear response would be useful. Results from the variable sensitivity model also indicate that management decisions regarding planting times, which have generally shifted toward earlier dates, have led to greater yield benefit than that implied by the single-sensitivity model. Together, the variation of both temperature trends and yield variability within growing stages calls for closer attention to how changes in management interact with changes in climate to ultimately affect yields.

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.

Endoscopic forceps biopsy (EFB) is a major diagnostic procedure for gastric epithelial neoplasia (GEN). However, discrepancy between the result of EFB and endoscopic resection (ER) is not uncommon. Thus, there is controversy over whether specimens obtained by EFB are optimal for diagnosis of GEN. We investigated the discrepancy between EFB and ER in the diagnosis of GEN. A total of 1,850 GEN cases were histologically diagnosed with EFB, including 954 low-grade dysplasias (LGDs), 315 high-grade dysplasias (HGDs), and 581 carcinomas. Following diagnosis with EFB, all patients were treated with ER. We retrospectively reviewed the pathologic findings and patient characteristics and analyzed predictors for the discrepancy between the two procedures (largest diameter, number of biopsy fragments, number of biopsy fragments/largest diameter, location, macroscopic type, color, surface unevenness, and erosion). The overall discrepancy rate between EFB and ER was 31.7 % (587/1,850). Among the discordant group, 440 (23.9 %) cases showed a higher grade of disease after ER; 229 of the 954 LGDs (24.0 %) were diagnosed as HGD or carcinoma, 166 of the 315 HGDs (52.7 %) as carcinoma, and 45 of the 581 differentiated carcinomas (7.7 %) as undifferentiated carcinoma. In the LGD group with EFB, the largest diameter (≥1.8 cm; P < 0.001), surface unevenness (P = 0.014), and depressed macroscopic type (P < 0.001) were factors associated with discrepancy. In the carcinoma group with EFB, flat macroscopic type (P = 0.043) was the only significant factor. In the HGD group with EFB, there were no significant factors for discrepancy. EFB can be insufficient for diagnosing GENs, and ER can be considered not only as treatment but also as a diagnostic modality in GEN. It is especially pertinent to all cases of HGD regardless of their endoscopic features and to cases of LGDs with the largest lesion diameter ≥1.8 cm, surface unevenness, or a depressed macroscopic type.

To determine the usefulness of autopsy findings in the quality improvement of patients care. An observational study. Departments of Pathology and Medicine, Combined Military Hospital (CMH) Kharian, a tertiary care hospital, from January 2001 to December 2003. 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. This study showed the usefulness of autopsy findings in the quality improvement of the diagnosis and management of the disease by showing only a minority of cases with discrepant diagnosis of the cause of death.

Adrenocorticotropic hormone (ACTH) stimulation is recommended in adrenal vein sampling (AVS) for primary aldosteronism (PA) to improve the AVS success rate. However, this method can confound the subtype diagnosis. Gene mutations or pathological characteristics may be related to lateralization by AVS. This study aimed to compare the rate of diagnostic discrepancy by AVS pre- versus post-ACTH stimulation and to investigate the relationship between this discrepancy and findings from immunohistochemical and genetic analyses of PA. We evaluated 195 cases of AVS performed in 2011–2017. All surgical specimens were analyzed genetically and immunohistochemically. Based on the criteria, AVS was successful in 158 patients both pre- and post-ACTH; of these patients, 75 showed diagnostic discrepancies between pre- and post-ACTH. Thus, 19 patients underwent unilateral adrenalectomy, of whom 16 had an aldosterone-producing adenoma (APA) that was positive for CYP11B2 immunostaining. Of them, 10 patients had discordant lateralization between pre- and post-ACTH. In the genetic analysis, the rate of somatic mutations was not significantly different between APA patients with versus without a diagnostic discrepancy. In the immunohistochemical analysis, CYP11B2 levels and the frequency of aldosterone-producing cell clusters (APCCs) in APAs were almost identical between patients with versus without a diagnostic discrepancy. However, both the number and summed area of APCCs in APAs were significantly smaller in patients with concordant results than in those whose diagnosis changed to bilateral PA post-ACTH stimulation. In conclusion, lateralization by AVS was affected by APCCs in the adjacent gland, but not by APA-related factors such as somatic gene mutations. PMID:29899838

The purpose of this study is to quantify the clinical impact of resident-attending discrepancies at a tertiary referral academic radiology residency program by assessing rates of intervention, discrepancy confirmation, recall rate, and management change rate; furthermore, a discrepancy categorization system will be assessed. Retrospective review of the records was performed for n = 1482 discrepancies that occurred in the 17-month study period to assess the clinical impact of discrepancies. Discrepancies were grouped according to a previously published classification system. Management changes were recorded and grouped by severity. The recall rate was estimated for discharged patients. Any confirmatory testing was reviewed to evaluate the accuracy of the discrepant report. Categorical variables were compared to the chi-square test. The 1482 discrepancies led to management change in 661 cases (44.6%). The most common management change was follow-up imaging. Procedural interventions including surgery occurred in 50 cases (3.3%). The recall rate was 2.6%. Management changes were more severe with computed tomography examinations, inpatients, and when the discrepancy was in the chest and abdomen subspecialty. Also, management changes correlated with the discrepancy category assigned by the attending at the time of review. Resident-attending discrepancies do cause management changes in 44.6% of discrepancies (0.62% overall); the most frequent change is follow-up imaging. The discrepancy categorization assigned by the attending correlated with the severity of management change. Copyright © 2018 The Association of University Radiologists. Published by Elsevier Inc.

Medication reconciliation is a part of the medication management process and facilitates improved patient safety during care transitions. The aims of the study were to evaluate how medication reconciliation has been conducted and how medication discrepancies have been classified. We searched MEDLINE, EMBASE, CINAHL, PubMed, International Pharmaceutical Abstracts (IPA), and Web of Science (WOS), in accordance with the PRISMA statement up to April 2016. Studies were eligible for inclusion if they evaluated the types of medication discrepancy found through the medication reconciliation process and contained a classification system for discrepancies. Data were extracted by one author based on a predefined table, and 10% of included studies were verified by two authors. Ninety-five studies met the inclusion criteria. Approximately one-third of included studies (n = 35, 36.8%) utilized a 'gold' standard medication list. The majority of studies (n = 57, 60%) used an empirical classification system and the number of classification terms ranged from 2 to 50 terms. Whilst we identified three taxonomies, only eight studies utilized these tools to categorize discrepancies, and 11.6% of included studies used different patient safety related terms rather than discrepancy to describe the disagreement between the medication lists. We suggest that clear and consistent information on prevalence, types, causes and contributory factors of medication discrepancy are required to develop suitable strategies to reduce the risk of adverse consequences on patient safety. Therefore, to obtain that information, we need a well-designed taxonomy to be able to accurately measure, report and classify medication discrepancies in clinical practice. © 2016 The British Pharmacological Society.

Autologous bone marrow-derived stem cell therapy in heart disease: discrepancies and contradictions.

Autologous bone marrow stem cell therapy is the greatest advance in the treatment of heart disease for a generation according to pioneering reports. In response to an unanswered letter regarding one of the largest and most promising trials, we attempted to summarise the findings from the most innovative and prolific laboratory. Amongst 48 reports from the group, there appeared to be 5 actual clinical studies ("families" of reports). Duplicate or overlapping reports were common, with contradictory experimental design, recruitment and results. Readers cannot always tell whether a study is randomised versus not, open-controlled or blinded placebo-controlled, or lacking a control group. There were conflicts in recruitment dates, criteria, sample sizes, million-fold differences in cell counts, sex reclassification, fractional numbers of patients and conflation of competitors' studies with authors' own. Contradictory results were also common. These included arithmetical miscalculations, statistical errors, suppression of significant changes, exaggerated description of own findings, possible silent patient deletions, fractional numbers of coronary arteries, identical results with contradictory sample sizes, contradictory results with identical sample sizes, misrepresented survival graphs and a patient with a negative NYHA class. We tabulate over 200 discrepancies amongst the reports. The 5 family-flagship papers (Strauer 2002, STAR, IACT, ABCD, BALANCE) have had 2665 citations. Of these, 291 citations were to the pivotal STAR or IACT-JACC papers, but 97% of their eligible citing papers did not mention any discrepancies. Five meta-analyses or systematic reviews covered these studies, but none described any discrepancies and all resolved uncertainties by undisclosed methods, in mutually contradictory ways. Meta-analysts disagreed whether some studies were randomised or "accepter-versus-rejecter". Our experience of presenting the discrepancies to journals is that readers may

Subjective-objective sleep discrepancy among older adults: associations with insomnia diagnosis and insomnia treatment.

Discrepancy between subjective and objective measures of sleep is associated with insomnia and increasing age. Cognitive behavioural therapy for insomnia improves sleep quality and decreases subjective-objective sleep discrepancy. 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 < 0.001 for all. Study of sleep discrepancy patterns may guide more targeted treatments for late-life insomnia. © 2014 European Sleep Research Society.

Parent-Child Discrepancy on Children's Body Weight Perception: The Role of Attachment Security.

PubMed

Uccula, Arcangelo; Nuvoli, Gianfranco

2017-01-01

The discrepancies between parents and their children on the description of the behavior and representations of their children have been shown in various studies. Other researchers have reported the parents' difficulty in correctly identifying the weight status of their children. The purpose of our study was to investigate the parent's attributional accuracy on their children's body weight perception in relation to the children attachment security. It was hypothesized that insecure children's parents have a greater discrepancy with their children compared to secure children with their parents. The research participants were 217 children, aged between 5 and 11 years of both genders, and their parents. The attachment pattern was measured by the SAT of Klagsbrun and Bowlby, with the Italian version of Attili. The children were also shown a set of figure body-drawings with which to measure the perception of their weight status. Parents answered a questionnaire to find out the parental attribution of their children's perception. The results show that the body weight perception of insecure children's parents have a greater discrepancy with their children's body weight perception compared with parentally secure children. In particular, parents of insecure children tend to underestimate the perception of their children. This result is most evident in disorganized children. In addition, the perception of insecure children's parents show a greater correlation with children's actual weight rather than with their children's perception. These results suggest that the discrepancies on the perception of children's body weight between parents and children may be influenced by the poor parental attunement to their children's internal states, which characterizes the insecure parent-child attachment relationship.

Although changes to self-identity or self-discrepancy are common after severe traumatic brain injury (TBI), the mechanisms underlying these changes are poorly understood. This study aimed to examine the influence of personality characteristics and cognitive appraisals on self-discrepancy. Participants were 51 adults (74% male) with severe TBI (M age = 36.22 years; SD = 12.65) who were on average 34 months (SD = 40.29) post-injury. They completed self-report measures of personality style (optimism and defensiveness), cognitive appraisals (threat appraisals, rumination and reflection and perceived coping resources), and self-discrepancy (Head Injury Semantic Differential Scale - III). Correlation analyses identified that higher levels of optimism, defensiveness and perceived coping resources were significantly associated with more positive self-discrepancy (r = .29-.47, p < .05), whereas higher threat appraisals and rumination were significantly related to more negative self-discrepancy (r = -.50-.57, p < .001). After controlling for personality characteristics, cognitive appraisals significantly accounted for self-discrepancy (R 2 change = .15). Moreover, rumination significantly mediated the relationship between optimism and self-discrepancy. In summary, cognitive appraisals were found to be related to self-discrepancy, independent of personality characteristics. Rumination in particular may be an important target of psychological intervention for individuals experiencing negative self-discrepancy.

Parent-Adolescent Discrepancies in Perceived Parenting Characteristics and Adolescent Developmental Outcomes in Poor Chinese Families.

Leung, Janet T Y; Shek, Daniel T L

2014-01-01

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.

To investigate the relationship between industry- vs nonindustry-funded publications comparing the efficacy of topical prostaglandin analogs by evaluating the correspondence between the statistical significance of the publication's main outcome measure and its abstract conclusions. Retrospective, observational cohort study. English publications comparing the ocular hypotensive efficacy between any or all of latanoprost, travoprost, and bimatoprost were searched from the MEDLINE database. Each article was reviewed by three independent observers and was evaluated for source of funding, study quality, statistically significant main outcome measure, correspondence between results of main outcome measure and abstract conclusion, number of intraocular pressure outcomes compared, and journal impact factor. Funding was determined by published disclosure or, in cases of no documented disclosure, the corresponding author was contacted directly to confirm industry funding. Discrepancies were resolved by consensus. The main outcome measure was correspondence between abstract conclusion and reported statistical significance of the publications' main outcome measure. Thirty-nine publications were included, of which 29 were industry funded and 10 were nonindustry funded. The published abstract conclusion was not consistent with the results of the main outcome measure in 18 (62%) of 29 of the industry-funded studies compared with zero (0%) of 10 of the nonindustry-funded studies (P = .0006). Twenty-six (90%) of the industry-funded studies had proindustry abstract conclusions. Twenty-four percent of the industry-funded publications had a statistically significant main outcome measure; however, 90% of the industry-funded studies had proindustry abstract conclusions. Both readers and reviewers should scrutinize publications carefully to ensure that data support the authors' conclusions.

The purpose of this bibliometric study was to assess the discrepancies between plastic surgery meeting abstracts and subsequent full-length manuscript publications. Abstracts presented at the Brazilian Congress of Plastic Surgery from 2010 to 2011 were compared with matching manuscript publications. Discrepancies between the abstract and the subsequent manuscript were categorized as major (changes in the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes in the title and authorship) variations. The overall discrepancy rate was 96 %, with at least one major (76 %) and/or minor (96 %) variation. There were inconsistencies between the study title (56 %), authorship (92 %), purpose (6 %), methods (20 %), study design (36 %), sample size (51.2 %), statistical analysis (14 %), results (20 %), and conclusions (8 %) of manuscripts compared with their corresponding meeting abstracts. As changes occur before manuscript publication of plastic surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts' content. This journal requires that authors assign a level of evidence to each article.

2016-10-01

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.

Masculine Discrepancy Stress, Teen Dating Violence, and Sexual Violence Perpetration Among Adolescent Boys

2018-01-01

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.

Measurement error: Implications for diagnosis and discrepancy models of developmental dyslexia.

PubMed

Cotton, Sue M; Crewther, David P; Crewther, Sheila G

2005-08-01

The diagnosis of developmental dyslexia (DD) is reliant on a discrepancy between intellectual functioning and reading achievement. Discrepancy-based formulae have frequently been employed to establish the significance of the difference between 'intelligence' and 'actual' reading achievement. These formulae, however, often fail to take into consideration test reliability and the error associated with a single test score. This paper provides an illustration of the potential effects that test reliability and measurement error can have on the diagnosis of dyslexia, with particular reference to discrepancy models. The roles of reliability and standard error of measurement (SEM) in classic test theory are also briefly reviewed. This is followed by illustrations of how SEM and test reliability can aid with the interpretation of a simple discrepancy-based formula of DD. It is proposed that a lack of consideration of test theory in the use of discrepancy-based models of DD can lead to misdiagnosis (both false positives and false negatives). Further, misdiagnosis in research samples affects reproducibility and generalizability of findings. This in turn, may explain current inconsistencies in research on the perceptual, sensory, and motor correlates of dyslexia.

2017-12-21

After-hours radiologic interpretation by nonradiology attendings or resident radiologists introduces the risk of discrepancies. Clinical outcomes following radiologic discrepancies among pediatric emergency department (ED) patients are poorly described. In particular, children with special healthcare needs (CSHCN), have more opportunities for discrepancies and potential consequences than non- CSHCN. Our objective was to determine the rates and types of radiologic discrepancies, and to compare CSHCN to non-CSHCN. From July 2014 to February 2015, all children who underwent a diagnostic imaging study at a free-standing children's ED were included. Data collected included radiologic studies - type and location - and clinical details - chief complaint and CSHCN type. Differences between preliminary reads and final pediatric radiology attending reads were defined as discrepancies, and categorized by clinical significance. Descriptive statistics, z-tests, and chi-square were used. Over 8months, 8310 visits (7462 unique patients) had radiologic studies (2620 CSHCN, 5690 non-CSHCN). A total of 198 (2.4%) radiologic discrepancies [56 (28.3%) CSHCN, 142 (71.7%) non-CSHCN] were found. Chief complaints for CSCHN were more often within the cardiac, pulmonary and neurologic systems (p<0.001 for each), whereas non-CSHCN presented with more trauma (p<0.001). The rates of discrepancies (CSHCN 2.1%, non- CSHCN 2.5%, p=0.3) and severity of clinical consequences (p=0.6) were not significantly different between CSHCN and non-CSHCN. Though the frequency and type of radiologic studies performed between CSHCN and non-CSHCN were different, we found no significant difference in the rate of radiologic discrepancies or the rate of clinically significant radiologic discrepancies.

To examine the relationship of mother-father informant discrepancies regarding diabetes management to diabetes-specific family conflict and glycemic control. One hundred thirty-six mothers and fathers of youth with Type 1 diabetes reported on the youth's diabetes management, diabetes-specific family conflict, and amount of paternal involvement in diabetes care. Glycosylated hemoglobin A1c (HbA1c) was used to measure glycemic control. As hypothesized, mother-father discrepancies regarding diabetes management were positively associated with frequency of diabetes-specific family conflict. Contrary to hypotheses, mother-father discrepancies regarding diabetes management predicted poorer glycemic control for youth with less involved fathers only. Results highlight the importance of caregivers being consistent about pediatric illness management and support the idea that informant discrepancies represent an important window into the functioning of the family system.

An electronic medication reconciliation tool was previously developed by another research team to aid provider-patient communication for medication reconciliation. To evaluate the usability of this tool, we integrated artificial safety probes into standard usability methods. The objective of this article is to describe this method of using safety probes, which enabled us to evaluate how well the tool supports users' detection of medication discrepancies. We completed a mixed-method usability evaluation in a simulated setting with 30 participants: 20 healthcare professionals (HCPs) and 10 patients. We used factual scenarios but embedded three artificial safety probes: (1) a missing medication (i.e., omission); (2) an extraneous medication (i.e., commission); and (3) an inaccurate dose (i.e., dose discrepancy). We measured users' detection of each probe to estimate the probability that a HCP or patient would detect these discrepancies. Additionally, we recorded participants' detection of naturally occurring discrepancies. Each safety probe was detected by ≤50% of HCPs. Patients' detection rates were generally higher. Estimates indicate that a HCP and patient, together, would detect 44.8% of these medication discrepancies. Additionally, HCPs and patients detected 25 and 45 naturally-occurring discrepancies, respectively. Overall, detection of medication discrepancies was low. Findings indicate that more advanced interface designs are warranted. Future research is needed on how technologies can be designed to better aid HCPs' and patients' detection of medication discrepancies. This is one of the first studies to evaluate the usability of a collaborative medication reconciliation tool and assess HCPs' and patients' detection of medication discrepancies. Results demonstrate that embedded safety probes can enhance standard usability methods by measuring additional, clinically-focused usability outcomes. The novel safety probes we used may serve as an initial, standard

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.

Analysis of F-16 radar discrepancies

NASA Astrophysics Data System (ADS)

Riche, K. A.

1982-12-01

One hundred and eight aircraft were randomly selected from three USAF F-16 bases and examined. These aircraft included 63 single-seat F-16As and 45 two-seat F-16Bs and encompassed 8,525 sorties and 748 radar system write-ups. Programs supported by the Statistical Package for the Social Sciences (SPSS) were run on the data. Of the 748 discrepancies, over one-third of them occurred within three sorties of each other and half within six sorties. Sixteen percent of all aircraft which had a discrepancy within three sorties had another write-up within the next three sorties. Designated repeat/recurring write-ups represented one-third of all the instances in which the write-up separation interval was three sorties or less. This is an indication that maintenance is unable to correct equipment failures as they occur, most likely because the false alarm rate is too high and maintenance is unable to duplicate the error conditions on the ground for correct error diagnosis.

On the Yield Strength of Oceanic Lithosphere

NASA Astrophysics Data System (ADS)

Jain, Chhavi; Korenaga, Jun; Karato, Shun-ichiro

2017-10-01

The yield strength of oceanic lithosphere determines the mode of mantle convection in a terrestrial planet, and low-temperature plasticity in olivine aggregates is generally believed to govern the plastic rheology of the stiffest part of lithosphere. Because, so far, proposed flow laws for this mechanism exhibit nontrivial discrepancies, we revisit the recent high-pressure deformation data of Mei et al. (2010) with a comprehensive inversion approach based on Markov chain Monte Carlo sampling. Our inversion results indicate that the uncertainty of the relevant flow law parameters is considerably greater than previously thought. Depending on the choice of flow law parameters, the strength of oceanic lithosphere would vary substantially, carrying different implications for the origin of plate tectonics on Earth. To reduce the flow law ambiguity, we suggest that it is important to establish a theoretical basis for estimating macroscopic stress in high-pressure experiments and also to better utilize marine geophysical observations.

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

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

Performing both propensity score and instrumental variable analyses in observational studies often leads to discrepant results: a systematic review.

Laborde-Castérot, Hervé; Agrinier, Nelly; Thilly, Nathalie

2015-10-01

Propensity score (PS) and instrumental variable (IV) are analytical techniques used to adjust for confounding in observational research. More and more, they seem to be used simultaneously in studies evaluating health interventions. The present review aimed to analyze the agreement between PS and IV results in medical research published to date. Review of all published observational studies that evaluated a clinical intervention using simultaneously PS and IV analyses, as identified in MEDLINE and Web of Science. Thirty-seven studies, most of them published during the previous 5 years, reported 55 comparisons between results from PS and IV analyses. There was a slight/fair agreement between the methods [Cohen's kappa coefficient = 0.21 (95% confidence interval: 0.00, 0.41)]. In 23 cases (42%), results were nonsignificant for one method and significant for the other, and IV analysis results were nonsignificant in most situations (87%). Discrepancies are frequent between PS and IV analyses and can be interpreted in various ways. This suggests that researchers should carefully consider their analytical choices, and readers should be cautious when interpreting results, until further studies clarify the respective roles of the two methods in observational comparative effectiveness research.

The aims of the study are to identify factors contributing to preliminary interpretive discrepancies on overnight radiology resident shifts and apply this data in the context of known literature to draw parallels to attending overnight shift work schedules. Residents in one university-based training program provided preliminary interpretations of 18,488 overnight (11 pm–8 am) studies at a level 1 trauma center between July 1, 2013 and December 31, 2014. As part of their normal workflow and feedback, attendings scored the reports as major discrepancy, minor discrepancy, agree, and agree--good job. We retrospectively obtained the preliminary interpretation scores for each study. Total relative value units (RVUs) per shift were calculated as an indicator of overnight workload. The dataset was supplemented with information on trainee level, number of consecutive nights on night float, hour, modality, and per-shift RVU. The data were analyzed with proportional logistic regression and Fisher's exact test. There were 233 major discrepancies (1.26 %). Trainee level (senior vs. junior residents; 1.08 vs. 1.38 %; p < 0.05) and modality were significantly associated with performance. Increased workload affected more junior residents' performance, with R3 residents performing significantly worse on busier nights. Hour of the night was not significantly associated with performance, but there was a trend toward best performance at 2 am, with subsequent decreased accuracy throughout the remaining shift hours. Improved performance occurred after the first six night float shifts, presumably as residents acclimated to a night schedule. As overnight shift work schedules increase in popularity for residents and attendings, focused attention to factors impacting interpretative accuracy is warranted.

Reporter Discrepancies Among Parents, Adolescents, and Peers: Adolescent Attachment and Informant Depressive Symptoms as Explanatory Factors

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

Orthodontic patients show high prevalence of tooth-size discrepancy. This study investigates the possible association between arch form, clinically significant tooth-size discrepancy, and sagittal molar relationship. Pretreatment orthodontic casts of 230 Saudi patients were classified into one of three arch form types (tapered, ovoid, and square) using digitally scanned images of the mandibular arches. Bolton ratio was calculated, sagittal molar relationship was defined according to Angle classification, and correlations were analyzed using ANOVA, chi-square, and t-tests. No single arch form was significantly more common than the others. Furthermore, no association was observed between the presence of significant Bolton discrepancy and the sagittal molar relationship or arch form. Overall Bolton discrepancy is significantly more prevalent in males. Arch form in a Saudi patient group is independent of gender, sagittal molar relationship, and Bolton discrepancy.

Precise spectroscopic information on the fast neutron induced fission of the 238U(n,f) reaction was recently gained using a new technique which involved coupling of the Miniball high resolution y-ray spectrometer and the LICORNE directional neutron source. The experiment allowed measurement of the isotopic fission yields for around 40 even-even nuclei at an incident neutron energy of around 2 MeV where yield data are very sparse. In addition spectroscopic information on very neutron-rich fission products was obtained. Results were compared to models, both the JEFF-3.1.1 data base and the GEF code, and large discrepancies for the S1 fission mode in the Sn/Mo isotope pair were discovered. This suggests that current models are overestimating the role played by spherical shell effects in fast neutron induced fission. In late 2017 and 2018 the nu-ball hybrid spectrometer will be constructed at the IPN Orsay to perform further experimental investigations with directional neutrons coupled to a powerful hybrid Ge/LaBr3 detector array. This will open up new possibilities for measurements of fission yields for fast-neutron-induced fission using the spectroscopic technique and will be complimentary to other methods being developed.

Histopathological Diagnostic Discrepancies in Soft Tissue Tumours Referred to a Specialist Centre: Reassessment in the Era of Ancillary Molecular Diagnosis

Thway, Khin; Mubako, Taka

2014-01-01

Introduction. Soft tissue tumour pathology is a highly specialised area of surgical pathology, but soft tissue neoplasms can occur at virtually all sites and are therefore encountered by a wide population of surgical pathologists. Potential sarcomas require referral to specialist centres for review by pathologists who see a large number of soft tissue lesions and where appropriate ancillary investigations can be performed. We have previously assessed the types of diagnostic discrepancies between referring and final diagnosis for soft tissue lesions referred to our tertiary centre. We now reaudit this 6 years later, assessing changes in discrepancy patterns, particularly in relation to the now widespread use of ancillary molecular diagnostic techniques which were not prevalent in our original study. Materials and Methods. We compared the sarcoma unit's histopathology reports with referring reports on 348 specimens from 286 patients with suspected or proven soft tissue tumours in a one-year period. Results. Diagnostic agreement was seen in 250 cases (71.8%), with 57 (16.4%) major and 41 (11.8%) minor discrepancies. There were 23 cases of benign/malignant discrepancies (23.5% of all discrepancies). 50 ancillary molecular tests were performed, 33 for aiding diagnosis and 17 mutational analyses for gastrointestinal stromal tumour to guide therapy. Findings from ancillary techniques contributed to 3 major and 4 minor discrepancies. While the results were broadly similar to those of the previous study, there was an increase in frequency of major discrepancies. Conclusion. Six years following our previous study and notably now in an era of widespread ancillary molecular diagnosis, the overall discrepancy rate between referral and tertiary centre diagnosis remains similar, but there is an increase in frequency of major discrepancies likely to alter patient management. A possible reason for the increase in major discrepancies is the increasing lack of exposure to soft tissue

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.

Medical error is a significant problem in the United States, and pathologic diagnoses are a significant source of errors. Prior studies have shown that second-opinion pathology review results in clinically major diagnosis changes in approximately 0.6% to 5.8% of patients. The few studies specifically on head and neck pathology have suggested rates of changed diagnoses that are even higher. Objectives .- To evaluate the diagnostic discrepancy rates in patients referred to our institution, where all such cases are reviewed by a head and neck subspecialty service, and to identify specific areas with more susceptibility to errors. Five hundred consecutive, scanned head and neck pathology reports from patients referred to our institution were compared for discrepancies between the outside and in-house diagnoses. Major discrepancies were defined as those resulting in a significant change in patient clinical management and/or prognosis. Major discrepancies occurred in 20 cases (4% overall). Informative follow-up material was available on 11 of the 20 patients (55.0%), among whom, the second opinion was supported in 11 of 11 cases (100%). Dysplasia versus invasive squamous cell carcinoma was the most common (7 of 20; 35%) area of discrepancy, and by anatomic subsite, the sinonasal tract (4 of 21; 19.0%) had the highest rate of discrepant diagnoses. Of the major discrepant diagnoses, 12 (12 of 20; 60%) involved a change from benign to malignant, one a change from malignant to benign (1 of 20; 5%), and 6 involved tumor classification (6 of 20; 30%). Head and neck pathology is a relatively high-risk area, prone to erroneous diagnoses in a small fraction of patients. This study supports the importance of second-opinion review by subspecialized pathologists for the best care of patients.

Salary discrepancies between male and female physicians are well documented; however, gender-based salary differences among clinically practicing physician assistants (PAs) have not been studied since 1992 (Willis, 1992). Therefore, the objectives of the current study are to evaluate the presence of salary discrepancies between clinically practicing male and female PAs and to analyze the effect of gender on income and practice characteristics. Using data from the 2009 American Academy of Physician Assistants' (AAPA) Annual Census Survey, we evaluated the salaries of PAs across multiple specialties. Differences between men and women were compared for practice characteristics (specialty, experience, etc) and salary (total pay, base pay, on-call pay, etc) in orthopedic surgery, emergency medicine, and family practice. Men reported working more years as a PA in their current specialty, working more hours per month on-call, providing more direct care to patients, and more funding available from their employers for professional development (p < .001, all comparisons). In addition, men reported a higher total income, base pay, overtime pay, administrative pay, on-call pay, and incentive pay based on productivity and performance (p < .001, all comparisons). Multivariate analysis of covariance and analysis of variance revealed that men reported higher total income (p < .0001) and base pay (p = .001) in orthopedic surgery, higher total income (p = .011) and base pay (p = .005) in emergency medicine, and higher base pay in family practice (p < .001), independent of clinical experience or workload. These results suggest that certain salary discrepancies remain between employed male and female PAs regardless of specialty, experience, or other practice characteristics. Copyright © 2012.

Sexual Closeness Discrepancies: What They Are and Why They Matter for Sexual Well-Being in Romantic Relationships.

Frost, David M; McClelland, Sara I; Dettmann, Miranda

2017-11-01

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.

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.

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, 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). Conclusion 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

A Discrepancy in Comprehension and Production in Early Language Development in ASD: Is it Clinically Relevant?

This study examined the extent to which a discrepant comprehension-production profile (i.e., relatively more delayed comprehension than production) is characteristic of the early language phenotype in autism spectrum disorders (ASD) and tracked the developmental progression of the profile. Our findings indicated that a discrepant comprehension-production profile distinguished toddlers (30 months) with ASD from late talkers without ASD (91% sensitivity, 100% specificity) in groups that were comparable on expressive language, age, and socioeconomic status. Longitudinal data for children with ASD revealed that the discrepant profile steadily decreased from 30 to 44 months until there was no significant comprehension-production difference at 66 months. In conclusion, results suggest that lower comprehension than production may be an age-specific marker of toddlers with ASD.

Associations between test-day milk yield and positive milk cultures for Staphylococcus aureus, Streptococcus spp., and other mastitis pathogens or a negative milk culture for mastitis pathogens were assessed in quarter milk samples from randomly sampled cows selected without regard to current or previous udder health status. Staphylococcus aureus was dichotomized according to sparse (< or =1,500 cfu/mL of milk) or rich (>1,500 cfu/mL of milk) growth of the bacteria. Quarter milk samples were obtained on 1 to 4 occasions from 2,740 cows in 354 Norwegian dairy herds, resulting in a total of 3,430 samplings. Measures of test-day milk yield were obtained monthly and related to 3,547 microbiological diagnoses at the cow level. Mixed model linear regression models incorporating an autoregressive covariance structure accounting for repeated test-day milk yields within cow and random effects at the herd and sample level were used to quantify the effect of positive milk cultures on test-day milk yields. Identical models were run separately for first-parity, second-parity, and third-parity or older cows. Fixed effects were days in milk, the natural logarithm of days in milk, sparse and rich growth of Staph. aureus (1/0), Streptococcus spp. (1/0), other mastitis pathogens (1/0), calving season, time of test-day milk yields relative to time of microbiological diagnosis (test day relative to time of diagnosis), and the interaction terms between microbiological diagnosis and test day relative to time of diagnosis. The models were run with the logarithmically transformed composite milk somatic cell count excluded and included. Rich growth of Staph. aureus was associated with decreased production levels in first-parity cows. An interaction between rich growth of Staph. aureus and test day relative to time of diagnosis also predicted a decline in milk production in third-parity or older cows. Interaction between sparse growth of Staph. aureus and test day relative to time of

EXOSIMS is an open-source simulation tool for parametric modeling of the detection yield and characterization of exoplanets. EXOSIMS has been adopted by the Exoplanet Exploration Programs Standards Definition and Evaluation Team (ExSDET) as a common mechanism for comparison of exoplanet mission concept studies. To ensure trustworthiness of the tool, we developed a validation test plan that leverages the Python-language unit-test framework, utilizes integration tests for selected module interactions, and performs end-to-end crossvalidation with other yield tools. This paper presents the test methods and results, with the physics-based tests such as photometry and integration time calculation treated in detail and the functional tests treated summarily. The test case utilized a 4m unobscured telescope with an idealized coronagraph and an exoplanet population from the IPAC radial velocity (RV) exoplanet catalog. The known RV planets were set at quadrature to allow deterministic validation of the calculation of physical parameters, such as working angle, photon counts and integration time. The observing keepout region was tested by generating plots and movies of the targets and the keepout zone over a year. Although the keepout integration test required the interpretation of a user, the test revealed problems in the L2 halo orbit and the parameterization of keepout applied to some solar system bodies, which the development team was able to address. The validation testing of EXOSIMS was performed iteratively with the developers of EXOSIMS and resulted in a more robust, stable, and trustworthy tool that the exoplanet community can use to simulate exoplanet direct-detection missions from probe class, to WFIRST, up to large mission concepts such as HabEx and LUVOIR.

Marginal discrepancy influenced by the choice of processing material used for the ceramic laminate veneers needs to be explored further for better clinical application. This study aimed to evaluate the amount of cervical and incisal marginal discrepancy associated with different ceramic laminate veneering materials. This was an experimental, single-blinded, in vitro trial. 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. ANOVA and post hoc Tukey honest significant difference (HSD) tests were used for statistical analysis. 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. 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.

Discrepancies between implicit and explicit motivation and unhealthy eating behavior.

Many people change their eating behavior as a consequence of stress. One source of stress is intrapersonal psychological conflict as caused by discrepancies between implicit and explicit motives. In the present research, we examined whether eating behavior is related to this form of stress. Study 1 (N=53), a quasi-experimental study in the lab, showed that the interaction between the implicit achievement motive disposition and explicit commitment toward an achievement task significantly predicts the number of snacks consumed in a consecutive taste test. In cross-sectional Study 2 (N=100), with a sample of middle-aged women, overall motive discrepancy was significantly related to diverse indices of unsettled eating. Regression analyses revealed interaction effects specifically for power and achievement motivation and not for affiliation. Emotional distress further partially mediated the relationship between the overall motive discrepancy and eating behavior.

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. PMID:29016602

Predictors of Nightly Subjective-Objective Sleep Discrepancy in Poor Sleepers over a Seven-Day Period

This study sought to examine predictors of subjective/objective sleep discrepancy in poor sleepers. Forty-two individuals with insomnia symptoms (mean age = 36.2 years, 81% female) were recruited to take part in a prospective study which combined seven days of actigraphy with daily assessment of sleep perceptions, self-reported arousal, sleep effort, and mood upon awakening. A high level of intra-individual variability in measures of sleep discrepancy was observed. Multilevel modelling revealed that higher levels of pre-sleep cognitive activity and lower mood upon awakening were significantly and independently predictive of the underestimation of total sleep time. Greater levels of sleep effort predicted overestimation of sleep onset latency. These results indicate that psychophysiological variables are related to subjective/objective sleep discrepancy and may be important therapeutic targets in the management of insomnia. PMID:28282912

The Symptoms and Functioning Severity Scale (SFSS): Psychometric Evaluation and Discrepancies among Youth, Caregiver, and Clinician Ratings over Time

Athay, M. Michele; Riemer, Manuel; Bickman, Leonard

2012-01-01

This paper describes the development and psychometric evaluation of the Symptoms and Functioning Severity Scale (SFSS), which includes three parallel forms to systematically capture clinician, youth, and caregiver perspectives of youth symptoms on a frequent basis. While there is widespread consensus that different raters of youth psychopathology vary significantly in their assessment this is the first paper that specifically investigates the discrepancies among clinician, youth, and caregiver ratings in a community mental health setting throughout the treatment process. Results for all three respondent versions indicate the SFSS is a psychometrically sound instrument for use in this population. Significant discrepancies in scores exist at baseline among the three respondents. Longitudinal analyses reveal the youth-clinician and caregiver-clinician score discrepancies decrease significantly over time. Differences by youth gender exist for caregiver-clinician discrepancies. The average youth-caregiver score discrepancy remains consistent throughout treatment. Implications for future research and clinical practice are discussed. PMID:22407556

2017-01-01

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.

Discrepancy between earthquake rates implied by historic earthquakes and a consensus geologic source model for California

We examine the difference between expected earthquake rates inferred from the historical earthquake catalog and the geologic data that was used to develop the consensus seismic source characterization for the state of California [California Department of Conservation, Division of Mines and Geology (CDMG) and U.S. Geological Survey (USGS) Petersen et al., 1996; Frankel et al., 1996]. On average the historic earthquake catalog and the seismic source model both indicate about one M 6 or greater earthquake per year in the state of California. However, the overall earthquake rates of earthquakes with magnitudes (M) between 6 and 7 in this seismic source model are higher, by at least a factor of 2, than the mean historic earthquake rates for both southern and northern California. The earthquake rate discrepancy results from a seismic source model that includes earthquakes with characteristic (maximum) magnitudes that are primarily between M 6.4 and 7.1. Many of these faults are interpreted to accommodate high strain rates from geologic and geodetic data but have not ruptured in large earthquakes during historic time. Our sensitivity study indicates that the rate differences between magnitudes 6 and 7 can be reduced by adjusting the magnitude-frequency distribution of the source model to reflect more characteristic behavior, by decreasing the moment rate available for seismogenic slip along faults, by increasing the maximum magnitude of the earthquake on a fault, or by decreasing the maximum magnitude of the background seismicity. However, no single parameter can be adjusted, consistent with scientific consensus, to eliminate the earthquake rate discrepancy. Applying a combination of these parametric adjustments yields an alternative earthquake source model that is more compatible with the historic data. The 475-year return period hazard for peak ground and 1-sec spectral acceleration resulting from this alternative source model differs from the hazard resulting from the

Laser flash photolysis of ozone - O/1D/ quantum yields in the fall-off region 297-325 nm

1980-01-01

The wavelength dependence of the quantum yield for O(1D) production from ozone photolysis has been determined between 297.5 nm and 325 nm in order to resolve serious discrepancies among previous studies. The results of this investigation are compared to earlier work by calculating atmospheric production rate constants for O(1D). It is found that for the purpose of calculating this rate constant, there is now good agreement among three studies at 298 K. Furthermore, it appears that previous data on the temperature dependence of the O(1D) quantum yield fall-off is adequate for determining the vertical profile of the O(1D) production rate constant. Several experimental difficulties associated with using NO2(asterisk) chemiluminescence to monitor O(1D) have been identified.

2010-12-01

Actual-ideal discrepancies are associated with adolescent emotional distress and there is evidence that the size of discrepancies matters. However, the direction of discrepancies has not been examined, perhaps due to limitations of widely used self-discrepancy measures. Two hundred and twelve 7th, 9th and 11th grade students (59% female) in a public school in Jamaica described their actual and ideal selves in several different domains--friendship, dating, schoolwork, family, sports, and religion/spirituality--using a Pie measure. Students also completed measures of depressive symptoms, self-esteem, and academic achievement. Discrepancies favoring the ideal self and those favoring the actual self were linked to depressive symptoms, low self-esteem, and poor school grades in the domains of friendship, dating, and schoolwork. Effects were stronger among older adolescents than among younger adolescents. Theories of actual/ideal self-discrepancies have focused on problems arising when the ideal self overshadows the actual self; however, the present study finds that self-discrepancies, regardless of their direction, are a liability. Implications for self-discrepancy measurement, adolescent development, and clinical practice are discussed.

Medication discrepancy: a concordance problem between dialysis patients and caregivers.

PubMed

Lindberg, Magnus; Lindberg, Per; Wikström, Björn

2007-01-01

Extensive drug utilization, and non-concordance between the patient and the caregiver about prescriptions and actual medicine intake, are associated with the risk of non-adherence to medication as well as medication-related illness. To achieve reliable estimates of drug use, it is important to consider the patient's self-reported drug utilization as well as to consult his/her medical record. The present multicentre study was conducted with the aim of examining the self-reported drug consumption of dialysis patients and its congruence with medical records. Consumption of pharmaceutical agents was recorded by 204 patients undergoing haemo- or peritoneal dialysis at 10 Swedish clinics. Drug record discrepancies were identified by comparing the self-reported use of prescribed medicines with the subsequently obtained medication lists. The median drug intake was 11 prescribed medicines and by including on-demand drugs this increased to 12. Discrepancies between the self-reported use of prescribed drugs and the medical record were prevalent in 80.4% of cases, with a median of three discrepancies per patient. Dialysis patients have an extensive need for medication but there is an undesirable deviation between consumption and prescription. A single medication list, accessible for the patient and for all prescribers, is a possible solution to achieve concordance but other measures, such as analysis of the reasons for discrepancy and tailored measures, would also benefit concordant medicine-taking.

National agencies such as USDA Foreign Agricultural Service (FAS), Production Estimation and Crop Assessment Division (PECAD) work specifically to analyze and generate timely crop yield estimates that help define national as well as global food policies. The USDA/FAS/PECAD utilizes a Decision Support System (DSS) called CADRE (Crop Condition and Data Retrieval Evaluation) mainly through an automated database management system that integrates various meteorological datasets, crop and soil models, and remote sensing data; providing significant contribution to the national and international crop production estimates. The "Sinclair" soybean growth model has been used inside CADRE DSS as one of the crop models. This project uses Sinclair model (a semi-mechanistic crop growth model) for its potential to be effectively used in a geo-processing environment with remote-sensing-based inputs. The main objective of this proposed work is to verify, validate and benchmark current and future NASA earth science research results for the benefit in the operational decision making process of the PECAD/CADRE DSS. For this purpose, the NASA South American Land Data Assimilation System (SALDAS) meteorological dataset is tested for its applicability as a surrogate meteorological input in the Sinclair model meteorological input requirements. Similarly, NASA sensor MODIS products is tested for its applicability in the improvement of the crop yield prediction through improving precision of planting date estimation, plant vigor and growth monitoring. The project also analyzes simulated Visible/Infrared Imager/Radiometer Suite (VIIRS, a future NASA sensor) vegetation product for its applicability in crop growth prediction to accelerate the process of transition of VIIRS research results for the operational use of USDA/FAS/PECAD DSS. The research results will help in providing improved decision making capacity to the USDA/FAS/PECAD DSS through improved vegetation growth monitoring from high

To describe the number of medication discrepancies associated with subsequent medication reconciliations by a clinical pharmacist in an ambulatory family medicine clinic and the proportion of subsequent medication reconciliation visits that were associated with hospital discharge, long-term anticoagulation management, or both. Data on medication reconciliations were collected over a 2-year time period in an ambulatory family medicine clinic for patients taking 10 or more medications. Medication reconciliation was performed 752 times for 500 patients. A total of 5,046 discrepancies were identified, with more than one-half deemed clinically important. A mean (± SD) of 6.7 ± 4.6 discrepancies per visit (3.5 ± 3.2 clinically important) were identified. The findings showed that the distribution of total discrepancies identified by pharmacist-performed medication reconciliation was significantly different over the course of subsequent medication reconciliations. However, the distribution of clinically important discrepancies was not significantly different; important discrepancies were as likely to be found in later reconciliations as in earlier ones. As subsequent medication reconciliation visits were performed, an increasing proportion consisted of post-hospital discharge visits, long-term anticoagulation managed by a clinical pharmacist, or both. Patients with a recent hospital discharge, on long-term anticoagulation management, or both, were more likely to have multiple sessions with a clinical pharmacist for medication reconciliation. These findings can help identify patients for whom medication reconciliation is warranted.

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.

Postmortem CT versus forensic autopsy: frequent discrepancies of tracheobronchial content findings.

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 < 30) in mismatching cases. The majority of causes of death were cardiac related in the matching cases and skull/brain trauma in the mismatching cases. In mismatching cases, frequency of pulmonary edema was significantly higher than in matching cases. It can be concluded that discrepancies in tracheobronchial contents observed between PMCT and routine forensic 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.

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.

Purpose This study aimed to establish 1) whether a group difference exists in the motor competence of preschool children at risk for developmental delays with intelligence quotient discrepancy (IQD; refers to difference between verbal intelligence quotient [VIQ] and performance intelligence quotient [PIQ]) and 2) whether an association exists between IQD and motor competence. Methods Children’s motor competence and IQD were determined with the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers and Wechsler Preschool and Primary Scale of Intelligence™ – Fourth Edition. A total of 291 children were included in three groups: NON-IQD (n=213; IQD within 1 standard deviation [SD]), VIQ>PIQ (n=39; VIQ>PIQ greater than 1 SD), and PIQ>VIQ (n=39; PIQ>VIQ greater than 1 SD). Results The results of one-way analysis of variance indicated significant differences among the subgroups for the “Gross and fine motor” subdomains of the Comprehensive Developmental Inventory for Infants and Toddlers, especially on the subtests of “body-movement coordination” (F=3.87, P<0.05) and “visual-motor coordination” (F=6.90, P<0.05). Motor competence was significantly worse in the VIQ>PIQ group than in the NON and PIQ>VIQ groups. Significant negative correlations between IQD and most of the motor subtests (r=0.31–0.46, P<0.01) were found only in the VIQ>PIQ group. Conclusion This study demonstrates that 1) IQD indicates the level of motor competence in preschoolers at risk for developmental delays and 2) IQD is negatively associated with motor competence in preschoolers with significant VIQ>PIQ discrepancy. The first finding was that preschoolers with VIQ>PIQ discrepancy greater than 1 SD performed significantly worse on motor competence than did preschoolers without significant IQD and preschoolers with PIQ>VIQ discrepancy greater than 1 SD. However, preschoolers with significant PIQ>VIQ discrepancy performed better on motor competence than

How binarity affect the abundance discrepancy in planetary nebulae

The discrepancy between chemical abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major unresolved problem in nebular astrophysics, with significant implications for the determination of chemical abundances throughout the Universe. In planetary nebulae (PNe), a common explanation of this discrepancy is that two different gas phases coexist: a hot component with standard metallicity, and a much cooler plasma with a highly enhanced content of heavy elements. This dual nature is not predicted by mass loss theories, and observational support for it is still weak. We present recent findings which show that the largest abundance discrepancies (ADs) are reached in PNe with close binary central stars. Our last long-slit spectroscopic studies as well as direct imaging of the gas in the faint O II ORLs and high spatial resolution IFU spectroscopy support the fact that probably two different gas phases coexist in these nebulae and that high ADs should be explained in a framework of binary evolution. Although the exact scenario is still not understood, a promising proposal is that nova-like ejecta have a crucial role in the strong ORL emission in these objects.

Discrepancies between implicit and explicit self-esteem among adolescents with social anxiety disorder.

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.

Explaining the discrepancy between forced fold amplitude and sill thickness.

NASA Astrophysics Data System (ADS)

Hoggett, Murray; Jones, Stephen M.; Reston, Timothy; Magee, Craig; Jackson, Christopher AL

2017-04-01

Understanding the behaviour of Earth's surface in response to movement and emplacement of magma underground is important because it assists calculation of subsurface magma volumes, and could feed into eruption forecasting. Studies of seismic reflection data have observed that the amplitude of a forced fold above an igneous sill is usually smaller than the thickness of the sill itself. This observation implies that fold amplitude alone provides only a lower bound for magma volume, and an understanding of the mechanism(s) behind the fold amplitude/sill thickness discrepancy is also required to obtain a true estimate of magma volume. Mechanisms suggested to explain the discrepancy include problems with seismic imaging and varying strain behaviour of the host rock. Here we examine the extent to which host-rock compaction can explain the fold amplitude/sill thickness discrepancy. This mechanism operates in cases where a sill is injected into the upper few kilometres of sedimentary rock that contain significant porosity. Accumulation of sediment after sill intrusion reduces the amplitude of the forced fold by compaction, but the sill itself undergoes little compaction since its starting porosity is almost zero. We compiled a database of good-quality 2D and 3D seismic observations where sill thickness has been measured independently of forced fold geometry. We then backstripped the post-intrusion sedimentary section to reconstruct the amplitude of the forced fold at the time of intrusion. We used the standard compaction model in which porosity decays exponentially below the sediment surface. In all examples we studied, post-sill-emplacement compaction can explain all of the fold amplitude/sill thickness discrepancy, subject to uncertainty in compaction model parameters. This result leads directly to an improved method of predicting magma volume from fold amplitude, including how uncertainty in compaction parameters maps onto uncertainty in magma volume. Our work implies

What to do? The effects of discrepancies, incentives, and time on dynamic goal prioritization.

PubMed

Schmidt, Aaron M; DeShon, Richard P

2007-07-01

This study examined factors that influence the dynamic pursuit of multiple goals over time. As hypothesized, goal-performance discrepancies were significantly related to subsequent time allocation. Greater distance from a given goal resulted in greater time subsequently allocated to that goal. In addition, the incentives offered for goal attainment determined the relative influence of discrepancies for each goal. When the incentives for each goal were equivalent, progress toward each goal exhibited equal influence, with greater time allocated to whichever goal was furthest from completion at the time. However, with an incentive available for only 1 of the 2 goals, time allocation was largely determined by progress toward the rewarded goal. Likewise, when incentives for each task differed in their approach-avoidance framing, progress toward the avoidance-framed goal was a stronger predictor of subsequent allocation than was progress toward the approach-framed goal. Finally, the influence of goal-performance discrepancies differed as a function of the time remaining for goal pursuit. The implications for future work on dynamic goal prioritization and the provision of performance incentives are discussed.

2012-04-01

When individuals grow up with autonomy-thwarting parents, they may be prevented from exploring internally endorsed values and identities and as a result shut out aspects of the self perceived to be unacceptable. Given the stigmatization of homosexuality, individuals perceiving low autonomy support from parents may be especially motivated to conceal same-sex sexual attraction, leading to defensive processes such as reaction formation. Four studies tested a model wherein perceived parental autonomy support is associated with lower discrepancies between self-reported sexual orientation and implicit sexual orientation (assessed with a reaction time task). These indices interacted to predict anti-gay responding indicative of reaction formation. Studies 2-4 showed that an implicit/explicit discrepancy was particularly pronounced in participants who experienced their fathers as both low in autonomy support and homophobic, though results were inconsistent for mothers. Findings of Study 3 suggested contingent self-esteem as a link between parenting styles and discrepancies in sexual orientation measures. (c) 2012 APA, all rights reserved.

Weight discrepancy and body appreciation among women in Poland and Britain.

Taylor, Donna; Szpakowska, Ilona; Swami, Viren

2013-09-01

Previous studies have suggested that the process of transmigration has detrimental effects on the body image of migrants relative to women in the country of origin. In the present work, we examined the body image of Polish migrants in Britain (n=153), Polish women in Poland (n=153), and a comparison group of British White women (n=110). Participants completed a measure of actual-ideal weight discrepancy and the Body Appreciation Scale (BAS). Contrary to hypotheses, our results showed that Polish women in Poland had significantly higher weight discrepancy than their counterparts in Britain. Further analyses showed that the BAS reduced to two dimensions among Polish participants, with Polish participants in Poland having significantly lower body appreciation than Polish migrants. We suggest that the sociocultural changes that have taken place in Eastern Europe may place women in that region at relatively high risk for developing negative body image.

Implicit and Explicit Self-Esteem Discrepancies, Victimization and the Development of Late Childhood Internalizing Problems.

PubMed

Leeuwis, Franca H; Koot, Hans M; Creemers, Daan H M; van Lier, Pol A C

2015-07-01

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.

Medication reconciliation is a safety practice to identify medication order discrepancies when patients' transitions between settings. In nursing homes, registered nurses (RNs) and licensed practical nurses (LPNs), each group with different education preparation and scope of practice responsibilities, perform medication reconciliation. However, little is known about how they differ in practice when making sense of medication orders to detect discrepancies. Therefore, the purpose of this study was to describe differences in RN and LPN sensemaking when detecting discrepancies. We used a qualitative methodology in a study of 13 RNs and 13 LPNs working in 12 Midwestern United States nursing homes. We used both conventional content analysis and directed content analysis methods to analyze semi-structured interviews. Four resident transfer vignettes embedded with medication order discrepancies guided the interviews. Participants were asked to describe their roles with medication reconciliation and their rationale for identifying medication order discrepancies within the vignettes as well as to share their experiences of performing medication reconciliation. The analysis approach was guided by Weick's Sensemaking theory. RNs provided explicit stories of identifying medication order discrepancies as well as examples of clinical reasoning to assure medication order appropriateness whereas LPNs described comparing medication lists. RNs and LPNs both acknowledged competing demands, but when performing medication reconciliation, RNs were more concerned about accuracy and safety, whereas LPNs were more concerned about time. Nursing home nurses, particularly RNs, are in an important position to identify discrepancies that could cause resident harm. Both RNs and LPNs are valuable assets to nursing home care and keeping residents safe, yet RNs offer a unique contribution to complex processes such as medication reconciliation. Nursing home leaders must acknowledge the differences

Objective 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. Setting A general teaching hospital in Tilburg, the Netherlands. Method 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. Main outcome measure The primary endpoint was the frequency of prescription errors in the discharge medication and medication discrepancies after discharge combined. Results 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)). Conclusion 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.

2011-01-01

To determine the initial compensation, preoperative decompensation, and postoperative compensation of the lower incisors according to the skeletal anteroposterior discrepancy and vertical type in skeletal Class III patients. The samples consisted of 68 skeletal Class III patients treated with two-jaw surgery and orthodontic treatment. Lateral cephalograms were taken before preoperative orthodontic treatment (T0) and before surgery (T1) and after debonding (T2). According to skeletal anteroposterior discrepancy/vertical type (ANB, criteria  =  -4°; SN-GoMe, criteria  =  35°) at the T0 stage, the samples were allocated into group 1 (severe anteroposterior discrepancy/hypodivergent vertical type, N  =  17), group 2 (moderate anteroposterior discrepancy/hypodivergent vertical type, N  =  17), group 3 (severe anteroposterior discrepancy/hyperdivergent vertical type, N  =  17), or group 4 (moderate anteroposterior discrepancy/hyperdivergent vertical type, N  =  17). After measurement of variables, one-way analysis of variance with Duncan's multiple comparison test, crosstab analysis, and Pearson correlation analysis were performed. At T0, groups 3 and 2 exhibited the most and least compensated lower incisors. In group 2, good preoperative decompensation and considerable postoperative compensation resulted in different values for T0, T1, and T2 (IMPA, T0 < T2 < T1; P < .001). However, group 3 did not show significant changes in IMPA between stages. Therefore, groups 2 and 3 showed different decompensation achievement ratios (P < .05). Group 3 exhibited the worst ratios of decompensation and stability (24% and 6%, respectively, P < .001). Anteroposterior discrepancy/vertical type (ANB: P < .01 at T0 and T1, P < .001 at T2; SN-GoMe: P < .01, all stages) were strongly correlated with relative percentage ratio of IMPA to norm value. Skeletal anteroposterior discrepancy/vertical type results in differences in the amount and pattern of initial

Medication discrepancy is a concept often used in discussions about medication safety but has neither been fully explained nor clearly defined in the literature. This article explores medication discrepancy as it relates to patient safety and population health in the management of medications. Literature review reveals 2 main aspects of discrepancies in medication management; prescribing issues and patient adherence to regimens. Further development of the concept of medication discrepancy can be beneficial to the theorist, researcher, or clinician. Conceptual clarity about the various aspects of medication discrepancy in the context of patient safety has the potential to enhance quality improvement efforts and patient outcomes to improve population health.

Discrepancy in Motivation for Weight Loss and Exercise in Rural Patients.

2017-11-01

We explored the extent to which discrepancy between motivation for weight loss and exercise is related to obesity among rural patients with chronic disease, and identified the psychosocial correlates of this discrepancy. 497 patients with diabetes and/or hypertension were recruited from a network of Federally Qualified Health Centers in the rural South and completed a battery of assessments. Most persons in the sample (83.1%) were overweight and 65.0% were obese. For motivation for change, 70.8% reported being in the Action stage or higher for weight loss, whereas only 24.9% reported being in the Action stage or higher for motivation for exercise. When controlling for age, education level, income, sex, and race/ethnicity, individuals who were motivated for weight loss but not exercise were twice as likely to be obese (p = .005). Race and sex were significantly associated with this discrepancy, with African-American patients 1.7 times as likely (p = .05) and women 2.3 times as likely to be discrepant (p = .001). Findings underscore the importance of focusing not simply on weight loss among rural patients with chronic disease, but rather to incorporate specific activities designed to build simultaneous motivation for engaging in exercise.

Discrepancies in parental and self-appraisals of prosocial characteristics predict emotional problems in adolescents.

Taylor, Peter J; Wood, Alex M

2013-09-01

Parental appraisals of an adolescent may have an effect upon the adolescent's well-being and likelihood of emotional problems. However, the impact of these parental appraisals is likely to be partly determined by the young person's self-appraisal. It was predicted that a discrepancy in self- and parent appraisals of positive, prosocial qualities would be associated with an increased risk of emotional problems. The study employed a cross-sectional design within a large sample of adolescent and caregiver dyads (N = 3,976, aged 11-17 years), drawn from the 'Mental health of children and young people in Great Britain, 2004' survey. Two separate measures of prosociality were used to ensure that effects were not specific to one measure. The analysis explored the discrepancy in parent and self-ratings on these measures via interactions within a logistic regression framework. Potential confounds, including gender, parental mental health, conduct and hyperkinetic problems were controlled for in the analysis. The logistic regression analyses demonstrated significant interactions between self- and parent ratings of prosocial qualities in predicting the odds of emotional disorder (i.e., depression and anxiety). This effect occurred across both measures of prosocial qualities whilst controlling for confounds. The pattern of the interactions suggested that low parental appraisals had a more detrimental effect on well-being when self-appraisals were highly positive. The results suggest that moderately high self-appraised positive traits may carry a cost of leaving young people more vulnerable to discrepant, negative parental appraisals. This has important implications for the meaning attributed to self-appraised positive traits in clinical contexts. Clinicians should be aware that the association between parental perceptions of a child's prosociality and emotional disorder may be influenced by the adolescents' self-perceptions. Clinicians should therefore endeavour to assess both

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

Unintended Medication Discrepancies Associated with Reliance on Prescription Databases for Medication Reconciliation on Admission to a General Medical Ward

2009-01-01

Background: In a recent study, 50% of the patients who were admitted to a hospital’s general medicine ward had at least one error in medication orders at the time of admission related to inaccuracies in the medication history. The use of computerized prescription databases has been suggested as a way to improve medication reconciliation at the time of admission. Objective: To quantify and describe unintended discrepancies between a best possible medication history and medications ordered on admission to the general medicine ward in a hospital with routine access to a provincial outpatient prescription database (British Columbia’s PharmaNet). Methods: This prospective study involved 20 patients who were regularly using at least 4 prescription medications before admission to hospital. The best possible medication history for each patient (based on a review of the medical chart and the PharmaNet record and an interview with the patient) was compared with the physician’s admission orders to identify any discrepancies. The frequency and perceived severity of discrepancies, graded independently by 3 physicians, were compared with observations from a similar study conducted at a hospital where a prescription database was not available. Results: The 20 patients were recruited between September 2005 and January 2006. For 8 patients (40%), information in the PharmaNet database was consistent with the prescription medication list obtained during the best possible medication history at the time of admission. For the other 12 patients, a total of 30 unintended discrepancies were identified, 13 (43%) of which were classified as having potential for moderate or severe harm. The proportion of patients with unintended discrepancies was similar to that for the comparison cohort (60% versus 54%). Although the percentage of discrepancies involving omissions was lower than in the comparison population (37% versus 46%), these results were offset by a higher proportion of

In medical practice, the dissatisfaction of patients about medical decisions made by doctors is often regarded as the fuse of doctor-patient conflict. However, a few studies have looked at why there are such dissatisfactions. This experimental study aimed to explore the discrepancy between attitude and behavior within medical situations and its interaction with framing description. A total of 450 clinical undergraduates were randomly assigned to six groups and investigated using the classic medical decision making problem, which was described either in a positive or a negative frame (2) × decision making behavior\\attitude to risky plan\\attitude to conservative plan (3). A discrepancy between attitude and behavior did exist in medical situations. Regarding medical dilemmas, if the mortality rate was described, subjects had a significant tendency to choose a conservative plan (t = 3.55, P < 0.01) yet if the survival rate was described, there was no such preference (t = -1.48, P > 0.05). However, regardless of the plan chosen by the doctor, the subjects had a significant opposing attitude (P < .05). Framing description had a significant impact on both decision making behavior and attitude (t behavior = -3.24, P < 0.01；t attitude to surgery = 4.08，P < 0.01；t attitude to radiation = -2.15，P < 0.05). A discrepancy of attitude-behavior does exist in medical situations. The framing of a description has an impact on medical decision-making.

A study of preservice elementary teachers enrolled in a discrepant-event-based physical science class

NASA Astrophysics Data System (ADS)

Lilly, James Edward

This research evaluated the POWERFUL IDEAS IN PHYSICAL SCIENCE (PIiPS) curriculum model used to develop a physical science course taken by preservice elementary teachers. The focus was on the evaluation of discrepant events used to induce conceptual change in relation to students' ideas concerning heat, temperature, and specific heat. Both quantitative and qualitative methodologies were used for the analysis. Data was collected during the 1998 Fall semester using two classes of physical science for elementary school teachers. The traditionally taught class served as the control group and the class using the PIiPS curriculum model was the experimental group. The PIiPS curriculum model was evaluated quantitatively for its influence on students' attitude toward science, anxiety towards teaching science, self efficacy toward teaching science, and content knowledge. An analysis of covariance was performed on the quantitative data to test for significant differences between the means of the posttests for the control and experimental groups while controlling for pretest. It was found that there were no significant differences between the means of the control and experimental groups with respect to changes in their attitude toward science, anxiety toward teaching science and self efficacy toward teaching science. A significant difference between the means of the content examination was found (F(1,28) = 14.202 and p = 0.001), however, the result is questionable. The heat and energy module was the target for qualitative scrutiny. Coding for discrepant events was adapted from Appleton's 1996 work on student's responses to discrepant event science lessons. The following qualitative questions were posed for the investigation: (1) what were the ideas of the preservice elementary students prior to entering the classroom regarding heat and energy, (2) how effective were the discrepant events as presented in the PIiPS heat and energy module, and (3) how much does the "risk taking

The aim of our study was to determine the incidence and causes of ABO typing discrepancies among patients and blood donors at our centre. An accurate interpretation of the ABO blood group of an individual is of utmost importance to ensure patient safety and good transfusion practices. A retrospective observational study was carried out in the Department of Transfusion Medicine in our hospital from March 2013 to December 2015. Records of all patient and blood donor samples were retrieved and analysed for ABO typing discrepancies. In total, 135 853 patient and 62 080 donor samples were analysed for ABO typing discrepancies. The incidence among patients and blood donors was found to be 0·1% (138/135853) and 0·02% (14/62080), respectively. The mean age for patients and blood donors was 48·4 and 29·2 years, respectively. The most common cause of ABO typing discrepancies was due to cold autoantibodies among the patients (50·7%) and blood donors (57%) causing discrepant results in reverse typing. The various other causes of reverse typing discrepancies among patients were weak/missing antibody (25·4%), cold-reacting alloantibody (4·3%), warm autoantibody (2·2%), anti-A1 antibody (2·2%), Bombay phenotype (1·5%), transplantation (0·7%) and rouleaux (0·7%), whereas in blood donors, the causes were cold-reacting antibody (7%) and weak antibody (7%). The major cause of forward typing discrepancies among patients (12·3%) and blood donors (29%) was ABO subgroups. The resolution of ABO typing discrepancy is essential to minimise the chance of transfusion of ABO-incompatible blood. © 2018 British Blood Transfusion Society.

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. 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. 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. A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

Empirical models are frequently applied to produce landslide susceptibility maps for large areas. Subsequent quantitative validation results are routinely used as the primary criteria to infer the validity and applicability of the final maps or to select one of several models. This study hypothesizes that such direct deductions can be misleading. The main objective was to explore discrepancies between the predictive performance of a landslide susceptibility model and the geomorphic plausibility of subsequent landslide susceptibility maps while a particular emphasis was placed on the influence of incomplete landslide inventories on modelling and validation results. The study was conducted within the Flysch Zone of Lower Austria (1,354 km2) which is known to be highly susceptible to landslides of the slide-type movement. Sixteen susceptibility models were generated by applying two statistical classifiers (logistic regression and generalized additive model) and two machine learning techniques (random forest and support vector machine) separately for two landslide inventories of differing completeness and two predictor sets. The results were validated quantitatively by estimating the area under the receiver operating characteristic curve (AUROC) with single holdout and spatial cross-validation technique. The heuristic evaluation of the geomorphic plausibility of the final results was supported by findings of an exploratory data analysis, an estimation of odds ratios and an evaluation of the spatial structure of the final maps. The results showed that maps generated by different inventories, classifiers and predictors appeared differently while holdout validation revealed similar high predictive performances. Spatial cross-validation proved useful to expose spatially varying inconsistencies of the modelling results while additionally providing evidence for slightly overfitted machine learning-based models. However, the highest predictive performances were obtained for

The Discrepancy between Einstein Mass and Dynamical Mass for SIS and Power-law Mass Models

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.

Introduction Marginal discrepancy severely affects the long term success of All ceramic complete veneer crowns. The precise role of resin luting agents influencing this phenomenon needs to be explored further. Aim To estimate and compare the marginal discrepancy in CAD/CAM processed All ceramic complete veneer crowns prior and following luting with resin bonded luting agents. Materials and Methods Extracted human maxillary first premolars were randomly allocated into four groups of 27 samples each Viz., Group I-Resin Modified Glass Ionomer Cement (GIC) (RelyX), Group II-Bis-GMA based dual cure resin cement (Variolink II), Group III-PMMA based resin cement (Superbond), Group IV- Urethane Dimethacrylate resin cement (Calibra). Following tooth preparation, CAD/CAM All ceramic complete veneer crowns were fabricated and sectioned and marginal discrepancy was evaluated using a scanning electron microscope (TESCAN, Magnification power-1,00,000x) prior and after luting with the experimental resin cements. Results The vertical and horizontal discrepancy before and after cementation with Group I [270.08±103.10μm, 165.3±53.00μm and 270.86±102.70μm, 166.62±54.96μm respectively]; Group II [254.21±79.20μm, 117.75±24.29μm and 234.81±79μm, 116.89±18.22μm respectively]; Group III [272.47±86.25μm, 142.08±50.83μm and 251.82±62.69μm, 136.07±44.95μm respectively]; Group IV were [260.28±64.81μm, 116.98±17.71μm and 233.08±69.44μm, 116.58±21.13μm respectively]. ANOVA inferred a statistically significant difference between the four test specimen with regards to vertical and horizontal marginal discrepancy after cementation (F=9.092, p<0.001), (F=10.97, p<0.001). Tukey HSD Post-hoc test observed significant differences in vertical and horizontal marginal discrepancies between the resin modified glass ionomer and resin cements (p<0.05). Conclusion Resin cements exhibited a greater reduction in the marginal discrepancy than the resin modified glass ionomer

This study aimed to establish 1) whether a group difference exists in the motor competence of preschool children at risk for developmental delays with intelligence quotient discrepancy (IQD; refers to difference between verbal intelligence quotient [VIQ] and performance intelligence quotient [PIQ]) and 2) whether an association exists between IQD and motor competence. Children's motor competence and IQD were determined with the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers and Wechsler Preschool and Primary Scale of Intelligence™ - Fourth Edition. A total of 291 children were included in three groups: NON-IQD (n=213; IQD within 1 standard deviation [SD]), VIQ>PIQ (n=39; VIQ>PIQ greater than 1 SD), and PIQ>VIQ (n=39; PIQ>VIQ greater than 1 SD). The results of one-way analysis of variance indicated significant differences among the subgroups for the "Gross and fine motor" subdomains of the Comprehensive Developmental Inventory for Infants and Toddlers, especially on the subtests of "body-movement coordination" (F=3.87, P<0.05) and "visual-motor coordination" (F=6.90, P<0.05). Motor competence was significantly worse in the VIQ>PIQ group than in the NON and PIQ>VIQ groups. Significant negative correlations between IQD and most of the motor subtests (r=0.31-0.46, P<0.01) were found only in the VIQ>PIQ group. This study demonstrates that 1) IQD indicates the level of motor competence in preschoolers at risk for developmental delays and 2) IQD is negatively associated with motor competence in preschoolers with significant VIQ>PIQ discrepancy. The first finding was that preschoolers with VIQ>PIQ discrepancy greater than 1 SD performed significantly worse on motor competence than did preschoolers without significant IQD and preschoolers with PIQ>VIQ discrepancy greater than 1 SD. However, preschoolers with significant PIQ>VIQ discrepancy performed better on motor competence than did preschoolers without significant IQD, though the

Parent-child acculturation discrepancy has been considered a risk factor for child maladjustment. The current study examined parent-child acculturation discrepancy as an ongoing risk factor for delinquency, through the mediating pathway of parental knowledge of the child's daily experiences relating to contact with deviant peers. Participants were drawn from a longitudinal project with 4 years between data collection waves: 201 Chinese immigrant families participated at Wave 1 (123 girls and 78 boys) and 183 families (110 girls and 73 boys) participated at Wave 2. Based on the absolute difference in acculturation levels (tested separately for Chinese and American orientations) between adolescents and parents, one parent in each family was assigned to the "more discrepant" group of parent-child dyads, and the other parent was assigned to the "less discrepant" group of parent-child dyads. To explore possible within-family variations, the mediating pathways were tested separately among the more and less discrepant groups. Structural equation modeling showed that the proposed mediating pathways were significant only among the more discrepant parent-adolescent dyads in American orientation. Among these dyads, a high level of parent-child acculturation discrepancy is related to adolescent perceptions of less parental knowledge, which is related to adolescents having more contact with deviant peers, which in turn leads to more adolescent delinquency. This mediating pathway is significant concurrently, within early and middle adolescence, and longitudinally, from early to middle adolescence. These findings illuminate some of the dynamics in the more culturally discrepant parent-child dyad in a family and highlight the importance of examining parent-child acculturation discrepancy within family systems.

Informative Disagreements: Associations Between Relationship Distress, Depression, and Discrepancy in Interpersonal Perception Within Couples.

Knobloch-Fedders, Lynne M; Critchfield, Kenneth L; Staab, Erin M

2017-06-01

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.

Discrepancy between subjective autobiographical reliving and objective recall: The past as seen by Alzheimer's disease patients.

PubMed

El Haj, Mohamad; Antoine, Pascal

2017-03-01

This paper investigated whether Alzheimer's disease (AD) patients may demonstrate a discrepancy between subjective autobiographical reliving and objective recall. To this end, 31 AD patients and 35 controls were asked to retrieve three autobiographical memories. For each memory, participants were asked to rate its subjective characteristics (e.g., reliving, travel in time, visual imagery…). Besides this subjective assessment, we analyzed recall objectively with regard to specificity. Results showed poorer subjective autobiographical reliving and objective recall in AD patients than in controls. A discrepancy (i.e., higher level of subjective reliving than of objective recall) was observed in AD but not in control participants. Despite a compromise in their objective recall, AD patients seemed to attribute a high value to their subjective autobiographical experience. This discrepancy can be attributed to a potential genuine consciousness experience in which mild AD patients can, to some extent, experience some subjective features of the past.

2011-01-01

The present study addressed convergence between self-report and indirect approaches to assessing dependency. The study was moderately successful in validating an implicit measure, which was found to be reliable, orthogonal to two self-report instruments, and predictive of external criteria. This study also examined discrepancies between scores on self-report and implicit measures, and has implications for their significance. The possibility that discrepancies themselves are pathological was not supported, although discrepancies were associated with particular personality profiles. Finally, this study offered additional evidence for the relation between dependency and depressive symptomatology, and identified implicit dependency as contributing unique variance in predicting past major depression.

Kim, Kyungmin; Zarit, Steven H; Birditt, Kira S; Fingerman, Karen L

2014-04-01

Using data from 929 parent-child dyads nested in 458 three-generation families (aged 76 for the oldest generation, 50 for the middle generation, and 24 for the youngest generation), this study investigated how discrepancies in reports of support that parents and their adult offspring exchanged with one another vary both within and between families, and what factors explain variations in dyadic discrepancies. We found substantial within- and between-family differences in dyadic discrepancies in reports of support exchanges. For downward exchanges (from parents to offspring), both dyad-specific characteristics within a family (e.g., gender composition, relative levels of relationship quality, and family obligation) and shared family characteristics (e.g., average levels of relationship quality) showed significant effects on dyadic discrepancies. For upward exchanges (from offspring to parents), however, only dyad-specific characteristics (e.g., gender composition, coresidence, relative levels of positive relationship quality, and family obligation) were significantly associated with discrepancies. Discrepancies in support exchanges were mainly associated with dyad-specific characteristics, but they also appeared to be influenced by family emotional environments. The use of multiple informants revealed that families differ in discrepancies in reports of exchanges, which has implications for quality of family life as well as future exchanges.

2018-01-01

Purpose 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. Methods 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. Results 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%). Conclusion 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. PMID:29510608

When do self-discrepancies predict negative emotions? Exploring formal operational thought and abstract reasoning skills as moderators.

2014-01-01

Individual differences in higher-order cognitive abilities may be an important piece to understanding how and when self-discrepancies lead to negative emotions. In the current study, three measures of reasoning abilities were considered as potential moderators of the relationship between self-discrepancies and depression and anxiety symptoms. Participants (N = 162) completed measures assessing self-discrepancies, depression and anxiety symptoms, and were administered measures examining formal operational thought, and verbal and non-verbal abstract reasoning skills. Both formal operational thought and verbal abstract reasoning were significant moderators of the relationship between actual:ideal discrepancies and depressive symptoms. Discrepancies predicted depressive symptoms for individuals with higher levels of formal operational thought and verbal abstract reasoning skills, but not for those with lower levels. The discussion focuses on the need to consider advanced reasoning skills when examining self-discrepancies.

Computerized follow-up of discrepancies in image interpretation between emergency and radiology departments.

PubMed

Siegel, E; Groleau, G; Reiner, B; Stair, T

1998-08-01

Radiographs are ordered and interpreted for immediate clinical decisions 24 hours a day by emergency physicians (EP's). The Joint Commission for Accreditation of Health Care Organizations requires that all these images be reviewed by radiologists and that there be some mechanism for quality improvement (QI) for discrepant readings. There must be a log of discrepancies and documentation of follow up activities, but this alone does not guarantee effective Q.I. Radiologists reviewing images from the previous day and night often must guess at the preliminary interpretation of the EP and whether follow up action is necessary. EP's may remain ignorant of the final reading and falsely assume the initial diagnosis and treatment were correct. Some hospitals use a paper system in which the EP writes a preliminary interpretation on the requisition slip, which will be available when the radiologist dictates the final reading. Some hospitals use a classification of discrepancies based on clinical import and urgency, and communicated to the EP on duty at the time of the official reading, but may not communicate discrepancies to the EP's who initial read the images. Our computerized radiology department and picture archiving and communications system have increased technologist and radiologist productivity, and decreased retakes and lost films. There are fewer face-to-face consultants of radiologists and clinicians, but more communication by telephone and electronic annotation of PACS images. We have integrated the QI process for emergency department (ED) images into the PACS, and gained advantages over the traditional discrepancy log. Requisitions including clinical indications are entered into the Hospital Information System and then appear on the PACS along with images on readings. The initial impression, time of review, and the initials of the EP are available to the radiologist dictating the official report. The radiologist decides if there is a discrepancy, and whether it

Objectives Discrepancies between leaders' self-ratings and follower 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 may be important for evidence-based practice implementation in mental health. Methods A total of 593 supervisors (i.e., leaders, n=80) and clinical service providers (i.e., followers, n=513) completed surveys including 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. Results 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 (i.e., “humble leaders”). Conclusions 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 evidence-based practice implementation and sustainment in mental health and other allied health settings.

2012-01-01

Background Medication discrepancies may occur on admission, transfer, or discharge from hospital. Therapeutic interchange within a drug class is a common practice in hospitals, and orders for specific proton pump inhibitors (PPIs) are often substituted with the hospital’s formulary PPI through therapeutic interchange protocols. Rabeprazole is the PPI on the formulary of the British Columbia PharmaCare program. However, different PPIs may appear on the formularies of the province’s hospitals. This misalignment and use of therapeutic interchange may lead to increased rates of medication discrepancies at the time of discharge. Objective To evaluate the effect of formulary misalignment for PPIs between St Paul’s Hospital in Vancouver and the British Columbia PharmaCare program and use of therapeutic interchange on the occurrence of medication discrepancies at discharge. Methods A cohort chart review was performed to compare discharge discrepancy rates for PPI orders between 2 periods: June 2006 to June 2008, when the same PPI appeared on the hospital and provincial formularies, and July 2008 to July 2010, when the designated PPIs differed between the hospital and provincial formularies. Data for the first study period were used to establish the baseline discharge discrepancy rate, and data for the later period represented the discharge discrepancy rate in the presence of misalignment between the hospital and PharmaCare formularies. Results The discharge discrepancy rate for PPIs was 27.3% (24/88) when the 2 formularies were aligned and 49.1% (81/165) when the formularies were misaligned. This represents an absolute increase of 21.8 percentage points in the risk of discharge discrepancies (95% confidence interval 9.8–33.9 percentage points; p < 0.001) when the hospital and provincial formularies were misaligned and the hospital’s therapeutic interchange protocol was used. Conclusions Misalignment between the PPIs specified in the hospital and provincial

Analysis of discrepancies observed between digital and analog images during a clinical trial of IRIS

A clinical trial of an Integrated Radiological Information System (IRIS) was conducted at the Ottawa Civic Hospital with the Department of Emergency Medicine and the Department of Radiological Sciences between April 4, and May 12, 1989. During the trial, 319 active Emergency Department cases (905 films) were processed using IRIS. Radiologists examined the digital images on the image screen to formulate a diagnosis, then before dictating a report, they examined the analog films. In 30 cases there was a discrepancy between the information obtained while viewing the digital images on IRIS and the information obtained from the analog films. These anomalous cases were used in an independent study of the discrepancies. In the study, each case was reviewed in both digital and analog form by three physicians who provided a comparative rating of diagnostic quality. Any perceived differences between the digital and analog media were noted. Particular attention was paid to rating the relevance of the IRIS enhancement capabilities. Although ratings for digital images were high, the comparative ratings for the film are in general better. An analysis of the individual cases shows that: (i) most of the discrepancies probably resulted from physician inexperience in reading radiographs in digital form, (ii) the IRIS enhancement facilities significantly increase the ratings of satisfaction or perceived quality of digital images and (iii) an appropriate choice of enhancement may make visible the required diagnostic features for cases where some reviewers did not find the image/digital discrepant.

The purpose of this investigation is to evaluate marginal discrepancy and fracture resistance of two veneering materials using two preparation designs. Two veneer preparation designs (full and traditional) were restored with leucite-reinforced ceramic (ProCAD, Ivoclar Vivadent, Amherst, NY) milled by CAD/CAM (Cerec 3D milling system, Serona Dental Systems), and conventional sintered feldspathic porcelain (Noritake Super Porcelain EX3, Noritake Dental Supply Co). Forty-eight specimens were analysed with a sample size of n=12 per group. The thickness of each veneer was measured on four specific surfaces. Marginal discrepancy was evaluated with a replica technique and cross-sectional view using a digital microscope. The fracture resistance of veneers cemented on standardised composite resin dies was evaluated using a universal testing machine. Results were analysed with ANOVA, Tukey-Kramer post hoc testing, and linear regression. The results of this investigation revealed no correlation between the thickness and marginal discrepancy of the veneers. The full preparation design with ProCAD and the traditional preparation design with feldspathic porcelain manifested smaller gap. Fracture resistance was decreased for the full preparation design with feldspathic porcelain. In terms of marginal discrepancy and fracture resistance, the most favourable combination was a traditional veneer preparation design with conventional sintered feldspathic porcelain. For the full veneer preparation, a stronger ceramic material such as ProCAD is suggested. Published by Elsevier Ltd.

In this study, we examined the internal consistency of informant discrepancies in reports of youth behavior and emotional problems and their unique relations with youth, caregiver, and family characteristics. In a heterogeneous multisite clinic sample of 420 youths (ages 11 to 17 years), high internal consistency estimates were observed across measures of informant discrepancies. Further, latent profile analyses identified systematic patterns of discrepancies, characterized by their magnitude and direction (i.e., which informant reported greater youth problems). Additionally, informant discrepancies systematically and uniquely related to informants' own perspectives of youth mood problems, and these relations remained significant after taking into account multiple informants' reports of informant characteristics widely known to relate to informant discrepancies. These findings call into the question the prevailing view of informant discrepancies as indicative of unreliability and/or bias on the part of informants' reports of youths' behavior. PMID:21229442

The Change Request (CR) assessment process is essential in the display development cycle. The assessment process is performed to ensure that the changes stated in the description of the CR match the changes in the actual display requirements. If a discrepancy is found between the CR and the requirements, the CR must be returned to the originator for corrections. Data will be gathered from each of the developers to determine the type of discrepancies and the amount of time spent assessing each CR. This study will determine the most common types of discrepancies and the amount of time spent assessing those issues. The results of the study will provide a foundation for future improvements as well as a baseline for future studies.

Summary Objectives: To determine the influence of maxillary posterior discrepancy on upper molar vertical position and dentofacial vertical dimensions in individuals with or without skeletal open bite (SOB). Materials and methods: Pre-treatment lateral cephalograms of 139 young adults were examined. The sample was divided into eight groups categorized according to their sagittal and vertical skeletal facial growth pattern and maxillary posterior discrepancy (present or absent). Upper molar vertical position, overbite, lower anterior facial height and facial height ratio were measured. Independent t-test was performed to determine differences between the groups considering maxillary posterior discrepancy. Principal component analysis and MANCOVA test were also used. Results: No statistically significant differences were found comparing the molar vertical position according to maxillary posterior discrepancy for the SOB Class I group or the group with adequate overbite. Significant differences were found in SOB Class II and Class III groups. In addition, an increased molar vertical position was found in the group without posterior discrepancy. Limitations: Some variables closely related with the individual’s intrinsic craniofacial development that could influence the evaluated vertical measurements were not considered. Conclusions and implications: Overall maxillary posterior discrepancy does not appear to have a clear impact on upper molar vertical position or facial vertical dimensions. Only the SOB Class III group without posterior discrepancy had a significant increased upper molar vertical position. PMID:26385786

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.

The Change Request (CR) assessment process is essential in the display development cycle. The assessment process is performed to ensure that the changes stated in the description of the CR match the changes in the actual display requirements. If a discrepancy is found between the CR and the requirements, the CR must be returned to the originator for corrections. Data was gathered from each of the developers to determine the type of discrepancies and the amount of time spent assessing each CR. This study sought to determine the most common types of discrepancies, and the amount of time required to assessing those issues. The study found that even though removing discrepancy before an assessment would save half the time needed to assess an CR with a discrepancy, the number of CR's found to have a discrepancy was very small compared to the total number of CR's assessed during the data gathering period.

Longitudinal Associations Between Parental Monitoring Discrepancy and Delinquency: An Application of the Latent Congruency Model.

2016-12-01

Studies have shown that discrepancies (relative concordance or discordance) between parent and adolescent ratings are predictive of problem behaviors; monitoring, in particular, has been consistently linked to them. The current study tested whether discrepancies in perceptions of maternal monitoring, rated by mothers and youth at age 12, foretold delinquency (rule breaking) at age 15, and whether parental closeness and conflict predicted higher discrepancies, and indirectly, higher delinquency. The final study sample used the NICHD longitudinal dataset with N = 966 youth (50.1 % female) and their mothers (80.1 % European American, 12.9 % African American, 7 % other ethnicity). The analytic approach consisted of an extension and application of the Latent Congruency Model (LCM) to estimate monitoring discrepancies as well as age 15 delinquency scores. Findings showed that age 12 monitoring discrepancy was predictive of age 15 delinquency for both boys and girls based on youth reports, but not for maternal reports. Age 11 closeness predicted age 12 monitoring discrepancy, which served as a mediator for its effect on age 15 adolescent-reported delinquency. Thus, based on the rigorous LCM analytic approach which seeks to minimize the effects by competing explanations and to maximize precision in providing robust estimates, rates of perceived discordance in parenting behaviors during early adolescence matter in understanding variability in adolescent delinquency during middle adolescence.

Imaging the elusive H-poor gas in planetary nebulae with large abundance discrepancy factors

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.

The Relationship of Explicit-Implicit Evaluative Discrepancy to Exercise Dropout in Middle-Aged Adults.

Berry, Tanya R; Rodgers, Wendy M; Divine, Alison; Hall, Craig

2018-06-19

Discrepancies between automatically activated associations (i.e., implicit evaluations) and explicit evaluations of motives (measured with a questionnaire) could lead to greater information processing to resolve discrepancies or self-regulatory failures that may affect behavior. This research examined the relationship of health and appearance exercise-related explicit-implicit evaluative discrepancies, the interaction between implicit and explicit evaluations, and the combined value of explicit and implicit evaluations (i.e., the summed scores) to dropout from a yearlong exercise program. Participants (N = 253) completed implicit health and appearance measures and explicit health and appearance motives at baseline, prior to starting the exercise program. The sum of implicit and explicit appearance measures was positively related to weeks in the program, and discrepancy between the implicit and explicit health measures was negatively related to length of time in the program. Implicit exercise evaluations and their relationships to oft-cited motives such as appearance and health may inform exercise dropout.

Diagnostic data routinely collected for hospital admitted patients and used for case-mix adjustment in care provider comparisons and reimbursement are prone to biases. We aim to measure discrepancies, variations and associated factors in recorded chronic morbidities for hospital admitted patients in New South Wales (NSW), Australia. Of all admissions between July 2010 and June 2014 in all NSW public and private acute hospitals, admissions with over 24 hours stay and one or more of the chronic conditions of diabetes, smoking, hepatitis, HIV, and hypertension were included. The incidence of a non-recorded chronic condition in an admission occurring after the first admission with a recorded chronic condition (index admission) was considered as a discrepancy. Poisson models were employed to (i) derive adjusted discrepancy incidence rates (IR) and rate ratios (IRR) accounting for patient, admission, comorbidity and hospital characteristics and (ii) quantify variation in rates among hospitals. The discrepancy incidence rate was highest for hypertension (51% of 262,664 admissions), followed by hepatitis (37% of 12,107), smoking (33% of 548,965), HIV (27% of 1500) and diabetes (19% of 228,687). Adjusted rates for all conditions declined over the four-year period; with the sharpest drop of over 80% for diabetes (47.7% in 2010 vs. 7.3% in 2014), and 20% to 55% for the other conditions. Discrepancies were more common in private hospitals and smaller public hospitals. Inter-hospital differences were responsible for 1% (HIV) to 9.4% (smoking) of variation in adjusted discrepancy incidences, with an increasing trend for diabetes and HIV. Chronic conditions are recorded inconsistently in hospital administrative datasets, and hospitals contribute to the discrepancies. Adjustment for patterns and stratification in risk adjustments; and furthermore longitudinal accumulation of clinical data at patient level, refinement of clinical coding systems and standardisation of comorbidity

Background Most publications about selective reporting in clinical trials have focussed on outcomes. However, selective reporting of analyses for a given outcome may also affect the validity of findings. If analyses are selected on the basis of the results, reporting bias may occur. The aims of this study were to review and summarise the evidence from empirical cohort studies that assessed discrepant or selective reporting of analyses in randomised controlled trials (RCTs). Methods and Findings A systematic review was conducted and included cohort studies that assessed any aspect of the reporting of analyses of RCTs by comparing different trial documents, e.g., protocol compared to trial report, or different sections within a trial publication. The Cochrane Methodology Register, Medline (Ovid), PsycInfo (Ovid), and PubMed were searched on 5 February 2014. Two authors independently selected studies, performed data extraction, and assessed the methodological quality of the eligible studies. Twenty-two studies (containing 3,140 RCTs) published between 2000 and 2013 were included. Twenty-two studies reported on discrepancies between information given in different sources. Discrepancies were found in statistical analyses (eight studies), composite outcomes (one study), the handling of missing data (three studies), unadjusted versus adjusted analyses (three studies), handling of continuous data (three studies), and subgroup analyses (12 studies). Discrepancy rates varied, ranging from 7% (3/42) to 88% (7/8) in statistical analyses, 46% (36/79) to 82% (23/28) in adjusted versus unadjusted analyses, and 61% (11/18) to 100% (25/25) in subgroup analyses. This review is limited in that none of the included studies investigated the evidence for bias resulting from selective reporting of analyses. It was not possible to combine studies to provide overall summary estimates, and so the results of studies are discussed narratively. Conclusions Discrepancies in analyses between

Parent-Child Discrepancies in Reports of Parental Monitoring and Their Relationship to Adolescent Alcohol-Related Behaviors.

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.

Real-time estimated longevity has been reported in pacemakers for several years, and was recently introduced in implantable cardioverter-defibrillators (ICDs). We sought to evaluate the accuracy of this longevity estimate in St. Jude Medical (SJM) ICDs, especially as the device battery approaches depletion. Among patients with SJM ICDs who underwent generator replacements due to reaching elective replacement indicator (ERI) at our institution, we identified those with devices that provided longevity estimates and reviewed their device interrogations in the 18 months prior to ERI. Significant discrepancy was defined as a difference of more than 12 months between estimated and actual longevity at any point during this period. Forty-six patients with Current/Promote devices formed the study group (40 cardiac resynchronization therapy [CRT] and 6 single/dual chamber). Of these, 34 (74%) had significant discrepancy between estimated and actual longevity (28 CRT and all single/dual). Longevity was significantly overestimated by the device algorithm (mean maximum discrepancy of 18.8 months), more in single/dual than CRT devices (30.5 vs. 17.1 months). Marked discrepancy was seen at voltages ≥2.57 volts, with maximum discrepancy at 2.57 volts (23 months). The overall longevity was higher in the discrepant group of CRT devices than in the nondiscrepant group (67 vs. 61 months, log-rank P = 0.03). There was significant overestimation of longevity in nearly three-fourths of Current/Promote SJM ICDs in the last 18 months prior to ERI. Longevity estimates of SJM ICDs may not be reliable for making clinical decisions on frequency of follow-up, as the battery approaches depletion. © 2017 Wiley Periodicals, Inc.

Brain dead or not? CT angiogram yielding false-negative result on brain death confirmation.

We describe a case of severe traumatic brain injury with multiple facial and skull fractures where CT angiogram (CTA) failed to yield a definite result of brain death as an ancillary test. A 28-year-old man was admitted following a road traffic accident with a Glasgow Coma Score (GCS) of 3/15 and fixed pupils. CT brain revealed uncal herniation and diffuse cerebral oedema with associated multiple facial and skull fractures. 72 h later, his clinical condition remained the same with high intracranial pressure refractory to medical management. Clinical confirmation on brain death was not feasible owing to facial injuries. A CTA, performed to determine brain perfusion, yielded a 'false-negative' result. Skull fractures have possibly led to venous prominence in the cortical and deep venous drainage system. This point needs to be borne in mind while considering CTA as an ancillary test to confirm brain death.

Soft tissue vascular malformations are generally diagnosed clinically, according to the International Society for the Study of Vascular Anomalies (ISSVA) classification. Diagnostic histopathologic examination is rarely performed. We sought to evaluate the validity of the current diagnostic workup without routinely performed diagnostic histopathology. We retrospectively determined whether there were discrepancies between clinical and histopathologic diagnoses of patients with clinically diagnosed vascular malformations undergoing therapeutic surgical resections in our center (2000-2015). Beforehand, a pathologist revised the histopathologic diagnoses according to the ISSVA classification. Clinical and histopathologic diagnoses were discrepant in 57% of 142 cases. In these cases, the pathologist indicated the diagnosis was not at all a vascular malformation (n = 24; 17%), a completely different type of vascular malformation (n = 26; 18%), or a partially different type with regard to the combination of vessel-types involved (n = 31; 22%). Possible factors associated with the discrepancies were both clinician-related (eg, diagnostic uncertainty) and pathology-related (eg, lack of immunostaining). Retrospective analysis of a subgroup of patients undergoing surgery. The large discrepancy between clinical and histopathologic diagnoses raises doubt about the validity of the current diagnostic workup for vascular malformations. Clear clinical and histopathologic diagnostic criteria might be essential for a uniform diagnosis. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

To (1) examine whether reducing discrepancies between goal importance and goal attainability is an adaptive predictor of well-being, (2) investigate intrusion, awareness, optimism, and pessimism as determinants of reducing discrepancies between goal importance and goal attainability, and (3) explore how goal progress is involved in reducing discrepancies between goal importance and goal attainability during two major periods after a colorectal cancer diagnosis. Prospective design. Newly diagnosed colorectal cancer patients (n = 120) were interviewed three times: within a month, 7 months (treatment period), and 18 months (follow-up period) post-diagnosis. Data were analysed using multiple regressions. Results showed that (1) reducing discrepancies enhances well-being, (2) optimism and pessimism are predictors of reducing discrepancies during the treatment period but not during the follow-up period, while intrusion and awareness do not predict reducing discrepancies in either period, and (3) goal progress is a predictor of reducing discrepancies during the follow-up period, but no evidence for a moderating or mediating role of goal progress in the relation between psychological characteristics and reducing discrepancies was found. Reducing discrepancies between goal importance and goal attainability could benefit colorectal cancer patients' well-being. Optimism, pessimism, and goal progress appear to influence cancer patients' ability to reduce discrepancies. Providing assistance in improving goal progress to those who are less optimistic and highly pessimistic may be a suitable training for cancer patients to prevent deterioration in well-being. Statement of contribution What is already known on this subject? More discrepancy between goal importance and goal attainability is associated with lower levels of well-being. People are able to change evaluations of importance and attainability, but it is unknown whether this positively impacts well-being. Underlying

The Longitudinal Association between Multiple Substance Use Discrepancies and Marital Satisfaction

AIMS 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 seven years of marriage. METHODS 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 year of marriage. RESULTS After controlling for key sociodemographic 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. CONCLUSIONS 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.

Cross-modal discrepancies in coarticulation and the integration of speech information: the McGurk effect with mismatched vowels.

PubMed

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.

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.

Data on fission yields and isomeric yield ratios (IYR) are tools to study the fission process, in particular the generation of angular momentum. We use the IGISOL facility with the Penning trap JYFLTRAP in Jyväskylä, Finland, for such measurements on 232Th and natU targets. Previously published fission yield data from IGISOL concern the 232Th(p,f) and 238U(p,f) reactions at 25 and 50 MeV. Recently, a neutron source, using the Be(p,n) reaction, has been developed, installed and tested. We summarize the results for (p,f) focusing on the first measurement of IYR by direct ion counting. We also present first results for IYR and relative yields for Sn and Sb isotopes in the 128-133 mass range from natU(n,f) based on γ-spectrometry. We find a staggering behaviour in the cumulative yields for Sn and a shift in the independent fission yields for Sb as compared to current evaluations. Plans for the future experimental program on fission yields and IYR measurements are discussed.

At teaching hospitals, radiology residents give preliminary reports for imaging studies requested from the Emergency Department (ED). Discrepancy rates between preliminary and final reports represent an important performance indicator. To present a system for feedback and follow-up of discrepancies, identify the variables associated with the rate and severity of such discrepancies, target the weaknesses, and suggest the need of a standard reference value for comparison among institutions. A monitoring and communication system between the Department of Diagnostic Radiology and Emergency Department was initiated to mark and follow all studies from the ED for which the official reading was different than the preliminary interpretation. Data analysis was performed on all studies from 1 June 2011 to 31 May 2012, based on the severity of the discrepancy, imaging modality, resident training level, and organ system. The distribution of the number of discrepancies among the different resident levels and imaging modalities was determined, as well as the distribution of three severity scores in correlation with other variables. The overall discrepancy rate was 1.62%. The discrepancy rate was higher for first and second year residents (1.62% and 1.96%) than for third and fourth year residents (1.35% and 1.24%). It was higher for computed tomography (2.13%) than for radiographs (1.29%) and ultrasound (0.8%) (P value < 0.01), and higher for musculoskeletal (1.61%) than non-musculoskeletal (0.99%) radiographs (P value = 0.0003). Discrepancies with severity score one constituted 35.5% of the total discrepancies, those with severity scores two and three constituted 22.9% and 41.6%, respectively. We have demonstrated a system for follow-up of discrepancy in interpreting emergency radiology studies, and recorded the discrepancy rate, with further analysis based on different variables. In terms of quality assurance, a periodical analysis might help to reduce the number of discrepant

To meet growing global food demand with limited land and reduced environmental impact, agricultural greenhouse gas (GHG) emissions are increasingly evaluated with respect to crop productivity, i.e., on a yield-scaled as opposed to area basis. Here, we compiled available field data on CH4 and N2 O emissions from rice production systems to test the hypothesis that in response to fertilizer nitrogen (N) addition, yield-scaled global warming potential (GWP) will be minimized at N rates that maximize yields. Within each study, yield N surplus was calculated to estimate deficit or excess N application rates with respect to the optimal N rate (defined as the N rate at which maximum yield was achieved). Relationships between yield N surplus and GHG emissions were assessed using linear and nonlinear mixed-effects models. Results indicate that yields increased in response to increasing N surplus when moving from deficit to optimal N rates. At N rates contributing to a yield N surplus, N2 O and yield-scaled N2 O emissions increased exponentially. In contrast, CH4 emissions were not impacted by N inputs. Accordingly, yield-scaled CH4 emissions decreased with N addition. Overall, yield-scaled GWP was minimized at optimal N rates, decreasing by 21% compared to treatments without N addition. These results are unique compared to aerobic cropping systems in which N2 O emissions are the primary contributor to GWP, meaning yield-scaled GWP may not necessarily decrease for aerobic crops when yields are optimized by N fertilizer addition. Balancing gains in agricultural productivity with climate change concerns, this work supports the concept that high rice yields can be achieved with minimal yield-scaled GWP through optimal N application rates. Moreover, additional improvements in N use efficiency may further reduce yield-scaled GWP, thereby strengthening the economic and environmental sustainability of rice systems. © 2013 John Wiley & Sons Ltd.

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

Size effects resolve discrepancies in 40 years of work on low-temperature plasticity in olivine

The strength of olivine at low temperatures and high stresses in Earth’s lithospheric mantle exerts a critical control on many geodynamic processes, including lithospheric flexure and the formation of plate boundaries. Unfortunately, laboratory-derived values of the strength of olivine at lithospheric conditions are highly variable and significantly disagree with those inferred from geophysical observations. We demonstrate via nanoindentation that the strength of olivine depends on the length scale of deformation, with experiments on smaller volumes of material exhibiting larger yield stresses. This “size effect” resolves discrepancies among previous measurements of olivine strength using other techniques. It also corroborates the most recent flow law for olivine, which proposes a much weaker lithospheric mantle than previously estimated, thus bringing experimental measurements into closer alignment with geophysical constraints. Further implications include an increased difficulty of activating plasticity in cold, fine-grained shear zones and an impact on the evolution of fault surface roughness due to the size-dependent deformation of nanometer- to micrometer-sized asperities.

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

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hwang, HL

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 Highwaymore » 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.« less

Parents’ and children’s autonomy and relatedness behaviors are associated with a wide range of child outcomes. Yet, little is known about how parents and children’s autonomy and relatedness behaviors jointly influence child outcomes. The current study captured this joint influence by exploring the longitudinal trajectory of mother–child discrepancies in autonomy and relatedness behaviors and its association with child problem behaviors. The effects of a family systems intervention on the trajectory of mother–child discrepancies were also examined. The sample included 183 substance using mothers and their children (M age = 11.54 years, SD = 2.55, range 8–16; 48 % females). Both the mother and child completed an assessment at baseline, 6- and 18-month post-baseline. A person-centered analysis identified subgroups varying in mother–child discrepancy patterns in their autonomy and relatedness behaviors. The results also showed that participation in the family systems therapy was associated with decreased mother–child discrepancies, and also a synchronous increase in mother’s and child’s autonomy and relatedness. Additionally, increased mother–child discrepancies and mother–child dyads showing no change in autonomy and relatedness was associated with higher levels of children’s problem behaviors. The findings reveal a dynamic process of mother–child discrepancies in autonomy and relatedness behaviors related to child outcomes. The findings also support the effectiveness of the family systems therapy, and highlight the importance of understanding the complexities in family interactions when explaining children’s problem behaviors.

A Class Il malocclusion is the most frequent sagittal skeletal disharmony presenting for orthodontic treatment. A transverse interarch discrepancy ITID) may be considered as a possible functional cause of a Class 11 relationship. The purpose of the present study was to determine transverse interarch width dimensions before and after orthodontic therapy and their possible relationship with increased mandibular projection following treatment. The sample included 40 adolescent patients who were divided into two groups, one possessing and one without a transverse discrepancy. Interarch width differences (including ICWD, IPWD, IMWD, IAWD) were measured before and after treatment, and Pogonion (Pog) to Nasion (NJ perpendicular was similarly measured in each group. The differences in arch and alveolar width dimensions between the two groups (including ICWD, IPWDI, IPWDII, IMWD, IAWD) before treatment were statistically significant (p < 0.05). A comparison of Pog to N perpendicular between the two groups showed that mandibular protrusion after treatment in the transverse discrepancy group was 2.6 ± 1.3 mm, while mandibular protrusion after treatment in the group without a transverse discrepancy was 0.6 ±0.3 mm. The statistical comparison showed that the differences were significant (p < 0.01). A transverse interarch discrepancy may have a functional relationship with mandible retrusion. If a transverse discrepancy is corrected via orthodontic treatment, the mandible may spontaneously protrude.

The mass discrepancy acceleration relation in a ΛCDM context

The mass discrepancy acceleration relation (MDAR) describes the coupling between baryons and dark matter (DM) in galaxies: the ratio of total-to-baryonic mass at a given radius anticorrelates with the acceleration due to baryons. The MDAR has been seen as a challenge to the Λ cold dark matter (ΛCDM) galaxy formation model, while it can be explained by Modified Newtonian Dynamics. In this Letter, we show that the MDAR arises in a ΛCDM cosmology once observed galaxy scaling relations are taken into account. We build semi-empirical models based on ΛCDM haloes, with and without the inclusion of baryonic effects, coupled to empirically motivated structural relations. Our models can reproduce the MDAR: specifically, a mass-dependent density profile for DM haloes can fully account for the observed MDAR shape, while a universal profile shows a discrepancy with the MDAR of dwarf galaxies with M⋆ < 109.5 M⊙, a further indication suggesting the existence of DM cores. Additionally, we reproduce slope and normalization of the baryonic Tully-Fisher relation (BTFR) with 0.17 dex scatter. These results imply that in ΛCDM (I) the MDAR is driven by structural scaling relations of galaxies and DM density profile shapes, and (II) the baryonic fractions determined by the BTFR are consistent with those inferred from abundance-matching studies.

Parent–child acculturation discrepancy has been considered a risk factor for child maladjustment. The current study examined parent–child acculturation discrepancy as an ongoing risk factor for delinquency, through the mediating pathway of parental knowledge of the child’s daily experiences relating to contact with deviant peers. Participants were drawn from a longitudinal project with 4 years between data collection waves: 201 Chinese immigrant families participated at Wave 1 (123 girls and 78 boys) and 183 families (110 girls and 73 boys) participated at Wave 2. Based on the absolute difference in acculturation levels (tested separately for Chinese and American orientations) between adolescents and parents, one parent in each family was assigned to the “more discrepant” group of parent–child dyads, and the other parent was assigned to the “less discrepant” group of parent–child dyads. To explore possible within-family variations, the mediating pathways were tested separately among the more and less discrepant groups. Structural equation modeling showed that the proposed mediating pathways were significant only among the more discrepant parent–adolescent dyads in American orientation. Among these dyads, a high level of parent–child acculturation discrepancy is related to adolescent perceptions of less parental knowledge, which is related to adolescents having more contact with deviant peers, which in turn leads to more adolescent delinquency. This mediating pathway is significant concurrently, within early and middle adolescence, and longitudinally, from early to middle adolescence. These findings illuminate some of the dynamics in the more culturally discrepant parent–child dyad in a family and highlight the importance of examining parent–child acculturation discrepancy within family systems.

Recent Results from Lohengrin on Fission Yields and Related Decay Properties

The Lohengrin mass spectrometer is one of the 40 instruments built around the reactor of the Institute Laue-Langevin (France) which delivers a very intense thermal neutron flux. Usually, Lohengrin was combined with a high-resolution ionization chamber in order to obtain good nuclear charge discrimination within a mass line, yielding an accurate isotopic yield determination. Unfortunately, this experimental procedure can only be applied for fission products with a nuclear charge less than about 42, i.e. in the light fission fragment region. Since 2008, a large collaboration has started with the aim of studying various fission aspects, mainly in the heavy fragment region. For that, a new experimental setup which allows isotopic identification by γ-ray spectrometry has been developed and validated. This technique was applied on the 239Pu(nth,f) reaction where about 65 fission product yields were measured with an uncertainty that has been reduced on average by a factor of 2 compared with what was that previously available in nuclear data libraries. The same γ-ray spectrometric technique is currently being applied to the study of the 233U(nth,f) reaction. Our aim is to deduce charge and mass distributions of the fission products and to complete the experimental data that exist mainly for light fission fragments. The measurement of 41 mass yields from the 241Am(2nth,f) reaction has been also performed. In addition to these activities on fission yield measurements, various new nanosecond isomers were discovered. Their presence can be revealed from a strong deformed ionic charge distribution compared to a 'normal' Gaussian shape. Finally, a new neutron long-counter detector designed to have a detection efficiency independent of the detected neutron energy has been built. Combining this neutron device with a Germanium detector and a beta-ray detector array allowed us to measure the beta-delayed neutron emission probability Pn of some important fission products for reactor

Objective To identify the most common areas for discrepancy in retinopathy of prematurity (ROP) classification between experts. Design Prospective cohort study. Subjects, Participants, and/or Controls 281 infants were identified as part of a multi-center, prospective, ROP cohort study from 7 participating centers. Each site had participating ophthalmologists who provided the clinical classification after routine examination using binocular indirect ophthalmoscopy (BIO), and obtained wide-angle retinal images, which were independently classified by two study experts. Methods Wide-angle retinal images (RetCam; Clarity Medical Systems, Pleasanton, CA) were obtained from study subjects, and two experts evaluated each image using a secure web-based module. Image-based classifications for zone, stage, plus disease, overall disease category (no ROP, mild ROP, Type II or pre-plus, and Type I) were compared between the two experts, and to the clinical classification obtained by BIO. Main Outcome Measures Inter-expert image-based agreement and image-based vs. ophthalmoscopic diagnostic agreement using absolute agreement and weighted kappa statistic. Results 1553 study eye examinations from 281 infants were included in the study. Experts disagreed on the stage classification in 620/1553 (40%) of comparisons, plus disease classification (including pre-plus) in 287/1553 (18%), zone in 117/1553 (8%), and overall ROP category in 618/1553 (40%). However, agreement for presence vs. absence of type 1 disease was >95%. There were no differences between image-based and clinical classification except for zone III disease. Conclusions The most common area of discrepancy in ROP classification is stage, although inter-expert agreement for clinically-significant disease such as presence vs. absence of type 1 and type 2 disease is high. There were no differences between image-based grading and the clinical exam in the ability to detect clinically-significant disease. This study provides

Estimation of corn yield using multi-temporal optical and radar satellite data and artificial neural networks

Fieuzal, R.; Marais Sicre, C.; Baup, F.

2017-05-01

The yield forecasting of corn constitutes a key issue in agricultural management, particularly in the context of demographic pressure and climate change. This study presents two methods to estimate yields using artificial neural networks: a diagnostic approach based on all the satellite data acquired throughout the agricultural season, and a real-time approach, where estimates are updated after each image was acquired in the microwave and optical domains (Formosat-2, Spot-4/5, TerraSAR-X, and Radarsat-2) throughout the crop cycle. The results are based on the Multispectral Crop Monitoring experimental campaign conducted by the CESBIO (Centre d'Études de la BIOsphère) laboratory in 2010 over an agricultural region in southwestern France. Among the tested sensor configurations (multi-frequency, multi-polarization or multi-source data), the best yield estimation performance (using the diagnostic approach) is obtained with reflectance acquired in the red wavelength region, with a coefficient of determination of 0.77 and an RMSE of 6.6 q ha-1. In the real-time approach the combination of red reflectance and CHH backscattering coefficients provides the best compromise between the accuracy and earliness of the yield estimate (more than 3 months before the harvest), with an R2 of 0.69 and an RMSE of 7.0 q ha-1 during the development of the central stem. The two best yield estimates are similar in most cases (for more than 80% of the monitored fields), and the differences are related to discrepancies in the crop growth cycle and/or the consequences of pests.

Photogrammetric determination of discrepancies between actual and planned position of dental implants

Forlani, G.; Rivara, F.

2014-05-01

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.

This study investigated the relationship between perceived mate value discrepancy (i.e., the difference between an individual's mate value and their partner's mate value) and perceived frequency of mate retention performed by an individual relative to his or her partner. In two studies, participants in long-term, exclusive, sexual, heterosexual relationships reported their own, and their partner's, mate value and mate retention. Samples included 899 community members (Study 1) and 941 students and community members (Study 2). In Study 1, we documented that individuals with higher self-perceived short-term mate value, and who perceive their partner to have lower (vs. higher) short-term mate value, perform less frequent Benefit-Provisioning mate retention, controlling for the partner's Benefit-Provisioning mate retention. In Study 2, we documented that individuals who perceive that they could less easily replace their partner, and who perceive their partner could more (vs. less) easily replace them, perform more frequent mate retention (Benefit-Provisioning and Cost-Inflicting), controlling for the partner's mate retention. These results highlight the importance of assessing perceived discrepancies in mate value (notably, regarding the replaceability of self and partner with another long-term mate) and perceived mate retention behaviors of self, relative to partner, between men and women in long-term relationships. © 2016 Wiley Periodicals, Inc.

Parents and children and adolescents commonly disagree in their perceptions of a variety of behaviors, including the family relationship and environment, and child and adolescent psychopathology. To this end, numerous studies have examined to what extent increased discrepant perceptions-particularly with regard to perceptions of the family relationship and environment-predict increased child and adolescent psychopathology. Parents' and children and adolescents' abilities to decode and identify others' emotions (i.e., emotion recognition) may play a role in the link between discrepant perceptions and child and adolescent psychopathology. We examined parents' and adolescents' emotion recognition abilities in relation to discrepancies between parent and adolescent perceptions of daily life topics. In a sample of 50 parents and adolescents ages 14-to-17 years (M = 15.4 years, 20 males, 54 % African-American), parents and adolescents were each administered a widely used performance-based measure of emotion recognition. Parents and adolescents were also administered a structured interview designed to directly assess each of their perceptions of the extent to which discrepancies existed in their beliefs about daily life topics (e.g., whether adolescents should complete their homework and carry out household chores). Interestingly, lower parent and adolescent emotion recognition performance significantly related to greater parent and adolescent perceived discrepant beliefs about daily life topics. We observed this relation whilst accounting for adolescent age and gender and levels of parent-adolescent conflict. These findings have important implications for understanding and using informant discrepancies in both basic developmental psychopathology research and applied research in clinic settings (e.g., discrepant views on therapeutic goals).

2004-03-01

We recently found documentation discrepancies in 60% of resident daily-progress notes with respect to patient weight, medications, or vascular lines. To what extent information systems can decrease such discrepancies is unknown. To determine whether a point-of-care personal digital assistant (PDA)-based patient record and charting system could reduce the number of resident progress-note documentation discrepancies in a neonatal intensive care unit (NICU). We conducted a before-and-after trial in an academic NICU. Our intervention was a PDA-based patient record and charting system used by all NICU resident physicians over the study period. We analyzed all resident daily-progress notes from 40 randomly selected days over 4 months in both the baseline and intervention periods. Using predefined reference standards, we determined the accuracy of recorded information for patient weights, medications, and vascular lines. Logistic and Poisson regression were used in analyses to control for potential confounding factors. A total of 339 progress notes in the baseline period and 432 progress notes in the intervention period were reviewed. When controlling for covariates in the regression, there were significantly fewer documentation discrepancies of patient weights in notes written by using the PDA system (14.4%-4.4% of notes; odds ratio [OR]: 0.29; 95% confidence interval [CI]: 0.15-0.56). When using the PDA system, there were no significant changes in the numbers of notes with documentation discrepancies of medications (27.7%-17.1% of notes; OR: 0.63; 95% CI: 0.35-1.13) or vascular lines (33.6%-36.1% of notes; OR: 1.11; 95% CI: 0.66-1.87). The use of our PDA-based point-of-care patient record and charting system showed a modest benefit in reducing the number of documentation discrepancies in resident daily-progress notes. Further study of PDAs in information systems is warranted before they are widely adopted.

We examined whether intra-family discrepancies in perceptions of the adolescent’s competence and independence were associated with autonomy and also well-being for adolescents and parents. The latent discrepancy model was used to examine the ways that mothers and fathers consistently differed from their adolescent across measures of independence and competence regarding type 1 diabetes, a stressful context for families. One-hundred and eighty-five mothers, fathers, and adolescents (M age= 12.5 SD= 1.3) completed measures of the adolescent’s independence in completing diabetes tasks, problems with diabetes management, adherence to the medical regimen, measures of well-being, and metabolic control. The latent discrepancy model was conducted via structural equation modeling that generated latent discrepancies from the adolescent for mothers and fathers. Both mothers and fathers viewed the adolescent’s competence more negatively than did the adolescent. These discrepancies related to more parental encouragement of independence and adolescent autonomy, but also poorer metabolic control, and poorer parental psychosocial well-being. The results are interpreted within a developmental perspective that views discrepancies as reflecting normative developmental processes of autonomy, but associated with disruptions in well-being in the short term.

This study examined whether intrafamily discrepancies in perceptions of the adolescent's competence and independence were associated with autonomy and well-being for adolescents and parents. The ways in which mothers and fathers consistently differed from their adolescent across measures of independence and competence regarding Type 1 diabetes, a stressful context for families, were examined with the latent discrepancy model. A sample of 185 adolescents (mean age = 12.5 years, SD = 1.3), their mothers, and participating fathers completed measures of the adolescent's independence in completing diabetes tasks, problems with diabetes management, adherence to the medical regimen, measures of well-being, and metabolic control. The latent discrepancy model was conducted via structural equation modeling that generated latent discrepancies from the adolescent for mothers and fathers. Both mothers and fathers viewed the adolescent's competence more negatively than did the adolescent. These discrepancies related to more parental encouragement of independence and adolescent autonomy but also to poorer metabolic control and poorer parental psychosocial well-being. The results are interpreted within a developmental perspective that views discrepancies as reflecting normative developmental processes of autonomy but as being associated with disruptions in well-being in the short term.

Because crowns with open margins are a well-known problem and can lead to complications, it is important to assess the accuracy of margins resulting from the use of a new technique. Currently, data regarding the marginal fit of computer-aided design and computer-aided manufacturing (CAD-CAM) technology to fabricate a complete gold crown (CGC) from a castable acrylate resin polymer block are lacking. The purpose of this in vitro study was to compare marginal discrepancy widths of CGCs fabricated by using either conventional hand waxing or acrylate resin polymer blocks generated by using CAD-CAM technology. A plastic model of a first mandibular molar was prepared by using a 1-mm, rounded chamfer margin on the entire circumference of the tooth. The master die was duplicated 30 times, and 15 wax patterns were fabricated by using a manual waxing technique, and 15 were fabricated by using CAD-CAM technology. All patterns were invested and cast, and resulting CGCs were cemented on their respective die by using resin-modified glass ionomer cement. The specimens were then embedded in acrylic resin and sectioned buccolingually. The buccal and lingual marginal discrepancies of each sectioned portion were measured by using microscopy at ×50 magnification. Data were subjected to repeated measures 2-way ANOVA, by using the Tukey post hoc pairwise comparison test (α=.05). The factor of "technique" had no significant influence on marginal discrepancy measurement (P=.431), but a significant effect of "margin location" (P=.019) was noted. The confounding combination of factors was found to be significantly lower marginal discrepancy dimensions of the lingual margin discrepancy than on the buccal side by using CAD-CAM technology. The marginal discrepancy of CAD-CAM acrylate resin crowns was not significantly different from those made with a conventional manual method; however, lingual margin discrepancies present from CAD-CAM-prepared crowns were significantly less than those

Introduction 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. Aim To assess the correlation between dermatoglyphic patterns and sagittal skeletal discrepancies. Materials and Methods 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. Results A significant association was observed between the dermatoglyphic pattern exhibited by eight fingers and the sagittal skeletal discrepancies (p<0.05). An increased distribution of whorl pattern was observed in the skeletal Class II with maxillary excess group and skeletal Class II with mandibular deficiency group while an increased distribution of loop pattern was seen in the skeletal Class III with mandibular excess group and skeletal Class III with maxillary deficiency group. Higher mean of total ridge count was also seen in the groups of skeletal Class II with maxillary excess and skeletal Class II with mandibular deficiency. Multinomial regression predicting skeletal pattern with respect to the fingerprint pattern showed that the left thumb impression fits the best model for predicting the skeletal pattern. Conclusion There was a

Replacement of the Faces subtest by Visual Reproductions within Wechsler Memory Scale-Third Edition (WMS-III) visual memory indexes: implications for discrepancy analysis.

Within discrepancy analysis differences between scores are examined for abnormality. Although larger differences are generally associated with rising impairment probabilities, the relationship between discrepancy size and abnormality varies across score pairs in relation to the correlation between the contrasted scores in normal subjects. Examinee ability level also affects the size of discrepancies observed normally. Wechsler Memory Scale-Third Edition (WMS-III) visual index scores correlate only modestly with other Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) and WMS-III index scores; consequently, differences between these scores and others have to be very large before they become unusual, especially for subjects of higher intelligence. The substitution of the Faces subtest by Visual Reproductions within visual memory indexes formed by the combination of WMS-III visual subtests (creating immediate recall, delayed recall, and combined immediate and delayed index scores) results in higher correlation coefficients, and a decline in the discrepancy size required to surpass base rate thresholds for probable impairment. This gain appears not to occur at the cost of a diminished sensitivity to diverse pathologies. New WMS-III discrepancy base rate data are supplied to complement those currently available to clinicians.

Marginal discrepancy is key to evaluating the accuracy of fixed dental prostheses. An improved method of evaluating marginal discrepancy is needed. The purpose of this in vitro study was to evaluate the absolute marginal discrepancy of ceramic crowns fabricated using conventional and digital methods with a digital method for the quantitative evaluation of absolute marginal discrepancy. The novel method was based on 3-dimensional scanning, iterative closest point registration techniques, and reverse engineering theory. Six standard tooth preparations for the right maxillary central incisor, right maxillary second premolar, right maxillary second molar, left mandibular lateral incisor, left mandibular first premolar, and left mandibular first molar were selected. Ten conventional ceramic crowns and 10 CEREC crowns were fabricated for each tooth preparation. A dental cast scanner was used to obtain 3-dimensional data of the preparations and ceramic crowns, and the data were compared with the "virtual seating" iterative closest point technique. Reverse engineering software used edge sharpening and other functional modules to extract the margins of the preparations and crowns. Finally, quantitative evaluation of the absolute marginal discrepancy of the ceramic crowns was obtained from the 2-dimensional cross-sectional straight-line distance between points on the margin of the ceramic crowns and the standard preparations based on the circumferential function module along the long axis. The absolute marginal discrepancy of the ceramic crowns fabricated using conventional methods was 115 ±15.2 μm, and 110 ±14.3 μm for those fabricated using the digital technique was. ANOVA showed no statistical difference between the 2 methods or among ceramic crowns for different teeth (P>.05). The digital quantitative evaluation method for the absolute marginal discrepancy of ceramic crowns was established. The evaluations determined that the absolute marginal discrepancies were

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.

Verbal-spatial discrepancies are common in healthy individuals and in those with neurodevelopmental disorders associated with cognitive control deficits including: Autism Spectrum Disorder, Non-Verbal Learning Disability, Fragile X, 22q11 deletion, and Turner Syndrome. Previous data from healthy individuals suggest that the magnitude of the difference between verbal IQ (VIQ) and performance IQ (PIQ) scores (the VIQ>PIQ discrepancy) is associated with reduced thickness in frontal and parietal cortices (inferior frontal, anterior cingulate, inferior parietal lobule, and supramarginal gyrus) that support cognitive control. Unknown is whether the VIQ>PIQ discrepancy is associated with functional deficits in these areas in healthy or ill children and adolescents. We assessed the effects of the VIQ>PIQ discrepancy on fMRI BOLD response during the resolution of cognitive conflict in 55 healthy children and adolescents during performance of a Simon Spatial Incompatibility task. As the magnitude of the VIQ>PIQ discrepancy increased, activation of fronto-striatal, limbic, and temporal regions decreased during conflict resolution (p < .05, corrected). In exploratory analyses, the VIQ>PIQ discrepancy was associated with reduced functional connectivity from right inferior frontal gyrus to right thalamus and increased functional connectivity to right supramarginal gyrus (ps < .03, uncorrected). The VIQ>PIQ discrepancy may be an important aspect of an individual's cognitive profile and likely contributes to, or is associated with, deficient cognitive control processes characteristic of many childhood disorders. © 2017 John Wiley & Sons Ltd.

Coparenting in immigrant Chinese Canadian families: the role of discrepancies in acculturation and expectations for adolescent assistance.

PubMed

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.

Identifying children with specific reading disabilities from listening and reading discrepancy scores.

PubMed

Spring, C; French, L

1990-01-01

A method of identifying children with specific reading disabilities by identifying discrepancies between their reading and listening comprehension scores was validated with disabled and nondisabled readers in Grades 4, 5, and 6. The method is based on a modification of the reading comprehension subtest of the Peabody Individual Achievement Test (Dunn & Markwardt, 1970). In this modification, even-numbered sentences are read by subjects, and odd-numbered sentences are read by the test administrator as subjects listen. The features of this test that reduce demands on working memory, thereby making it suitable for the detection of a discrepancy between reading and listening comprehension in readers with disabilities, are discussed. A significant group-by-modality interaction was obtained. Children with reading disabilities scored significantly lower on reading than on listening comprehension, while nondisabled readers scored slightly higher, but not significantly so, on reading than on listening comprehension. The appropriateness of this method as a substitute for the traditional method, which is based on the detection of a discrepancy between intelligence and reading and which has recently been proscribed in certain school districts, is discussed. Issues concerning the listening comprehension skills of disabled readers are also discussed.

Specific yield: compilation of specific yields for various materials

USGS Publications Warehouse

Johnson, A.I.

1967-01-01

Specific yield is defined as the ratio of (1) the volume of water that a saturated rock or soil will yield by gravity to (2) the total volume of the rock or soft. Specific yield is usually expressed as a percentage. The value is not definitive, because the quantity of water that will drain by gravity depends on variables such as duration of drainage, temperature, mineral composition of the water, and various physical characteristics of the rock or soil under consideration. Values of specific yields nevertheless offer a convenient means by which hydrologists can estimate the water-yielding capacities of earth materials and, as such, are very useful in hydrologic studies. The present report consists mostly of direct or modified quotations from many selected reports that present and evaluate methods for determining specific yield, limitations of those methods, and results of the determinations made on a wide variety of rock and soil materials. Although no particular values are recommended in this report, a table summarizes values of specific yield, and their averages, determined for 10 rock textures. The following is an abstract of the table. [Table

Acid soil infertility effects on peanut yields and yield components

Blamey, F.P.C.

1983-01-01

The interpretation of soil amelioration experiments with peanuts is made difficult by the unpredictibility of the crop and by the many factors altered when ameliorating acid soils. The present study was conducted to investigate the effects of lime and gypsum applications on peanut kernel yield via the three first order yield components, pods per ha, kernels per pod, and kernel mass. On an acid medium sandy loam soil (typic Plinthustult), liming resulted in a highly significant kernel yield increase of 117% whereas gypsum applications were of no significant benefit. As indicated by path coefficient analysis, an increase in the numbermore » of pods per ha was markedly more important in increasing yield than an increase in either the number of kernels per pod or kernel mass. Furthermore, exch. Al was found to be particularly detrimental to pod number. It was postulated that poor peanut yields resulting from acid soil infertility were mainly due to the depressive effect of exch. Al on pod number. Exch. Ca appeared to play a secondary role by ameliorating the adverse effects of exch. Al.« less

Context This invitro study was conducted to compare and evaluate marginal discrepancy in two types of tooth colored self cure provisional restorative materials {DPI&UNIFAST TRAD} before and after reinforcement of glass beads. Aim The aim of the present study was to evaluate and compare marginal discrepancy in two types of provisional restorative materials (DPI and UNI FAST TRAD) before and after reinforcement with Glass beads. Materials and Methods Tooth shaped resin copings were fabricated on custom made brass metal die. A total of 60 resin copings were fabricated in which 30 samples were prepared with DPI and 30 samples with UNIFAST material. Each group of 30 samples were divided in to two sub groups in which 15 samples were prepared with glass bead reinforcement and 15 samples without reinforcement. The marginal discrepancy was evaluated with photomicroscope {Reichet Polyvar 2 met} by placing the resin copings on custom made brass resin coping holder. Results Measurements obtained were statistically analysed by unpaired t-test to know any significance between two variables. Unreinforced DPI specimens had shown lower marginal discrepancy (442.82) than reinforced specimens (585.77). Unreinforced UNIFAST specimens have shown high values of marginal discrepancy (592.83) than reinforced specimens (436.35). p-value between reinforced and unreinforced specimens of DPI (p=0.0013) and UNIFAST (p= 0.0038) has shown statistical significance. Conclusion This in-vitro study revealed that unreinforced DPI specimens have shown lower marginal discrepancy than reinforced specimens and unreinforced UNIFAST specimens have shown higher values of marginal discrepancy than reinforced specimens.

Marginal and axial discrepancies of metal ceramic restorations are key to their long-term success. Little information is available for metal ceramic restorations fabricated with soft metal milling and laser sintering technologies. The purpose of this in vitro study was to compare the marginal, axial, and occlusal discrepancies in single-unit metal ceramic restorations fabricated with new production techniques with those in a single-unit restoration fabricated using a conventional technique. After the artificial tooth was prepared, impressions were made, and 40 dies were obtained. Dies were randomly divided into 4 groups (n=10). Cobalt-chromium (Co-Cr) cast (C), hard metal milled (HM), laser sintered (LS), and soft metal milled (SM) copings were fabricated. Marginal, axial, and occlusal discrepancies of these copings were measured using the silicone replica technique before and after the application of veneering ceramic. Data were analyzed with repeated measurements 2-way ANOVAs and Bonferroni post hoc tests (α=.05). Significant differences were found in the increase of marginal discrepancy after the application of veneering ceramic in the LS group (P=.016). However, no significant differences in marginal discrepancy were found whether veneering ceramic was applied to copings before or after in the other groups (P>.05). With regard to marginal and occlusal discrepancies, significant differences were found among the production techniques (P<.001 and P<.05, respectively). No significant differences in axial discrepancies were found among the groups (P>.05). This in vitro study showed that metal ceramic restorations produced with HM and newly introduced SM techniques exhibited better marginal adaptations than those produced with the LS or C technique.

2015-01-01

Background If delusions serve as a defense mechanism in schizophrenia patients with paranoia, then they should show normal or high explicit self-esteem and low implicit self-esteem. However, the results of previous studies are inconsistent. One possible explanation for this inconsistency is that there are two types of paranoia, “bad me” (self-blaming) paranoia and “poor me” (non-self-blaming) paranoia. We thus examined implicit and explicit self-esteem and self-blaming tendency in patients with schizophrenia and schizoaffective disorder. We hypothesized that patients with paranoia would show lower implicit self-esteem and only those with non-self-blaming paranoia would experience a discrepancy between explicit and implicit self-esteem. Methods Participants consisted of patients with schizophrenia and schizoaffective disorder recruited from a day hospital (N=71). Participants were assessed for psychotic symptoms, using the Brief Psychiatric Rating Scale (BPRS), and self-blaming tendency, using the brief COPE. We also assessed explicit self-esteem, using the Rosenberg Self-Esteem Scale (RSES), implicit self-esteem, using Brief Implicit Association Test (BIAT), and discrepancy between explicit and implicit self-esteem. Results Contrary to our hypothesis, implicit self-esteem in paranoia and nonparanoia showed no statistical difference. As expected, only patients with non-self-blaming paranoia experienced a discrepancy between explicit and implicit self-esteem; other groups showed no such discrepancy. Conclusion These results suggest that persecutory delusion plays a defensive role in non-self-blaming paranoia. PMID:25565849

Knowledge vs. Action: Discrepancies in University Students' Knowledge about and Self-Reported Use of Self-Regulated Learning Strategies.

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.

Adaptive elements of aging: Self-image discrepancy, perfectionism, and eating problems.

PubMed

Landa, Carrie E; Bybee, Jane A

2007-01-01

Age-related changes in personality variables that may contribute to the reduction of symptoms of eating disorders with adult development were examined. Undergraduate sorority women (n = 52; mean age = 19.85 years) were compared with alumnae of the same sorority (n = 34; mean age = 33.74 years). Eating pathology was correlated with greater discrepancy between the real (current) and the ideal (desired) self-image and with perfectionism. Both self-image discrepancy and perfectionism were markedly lower among the alumnae. Variance in these variables together accounted for the lowered level of eating pathology among the older participants. Specific content domains of the real and ideal self-image and different facets of perfectionism showed distinctive age-related changes and differential relationships with eating pathology.

2015-01-01

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.

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.

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.

Understanding factors related to girls' body image discrepancy, which is the difference between self-perceived current or actual and ideal body size, is important for addressing body-related issues and preventing adverse sequelae. Two aims were to: 1) examine demographic differences in body image discrepancy; and 2) determine the association of body image discrepancy with weight status, percent body fat, physical activity, sedentary behavior, and cardiovascular (CV) fitness among young adolescent girls. The cross-sectional study included a secondary analysis of baseline data from a group randomized controlled trial including 1519 5th-8th grade girls in 24 U.S. schools. Girls completed physical activity and sedentary behavior surveys. To indicate perceived current/actual and ideal body image, girls selected from nine body figures the one that represented how they look now and another showing how they want to look. Girls wore accelerometers measuring physical activity. Height, weight, and percent body fat were assessed. The Progressive Aerobic CV Endurance Run was used to estimate CV fitness. Independent t-test, one- and two-way ANOVA, correlational analyses, and hierarchical linear regressions were performed. The majority (67.5%; n = 1023) chose a smaller ideal than current/actual figure. White girls had higher body image discrepancy than Black girls (p = .035). Body image discrepancy increased with increasing weight status (F 3,1506  = 171.32, p < .001). Moderate-to-vigorous physical activity (MVPA) and vigorous physical activity were negatively correlated with body image discrepancy (r = -.10, p < .001; r = -.14, p < .001, respectively), but correlations were not significant after adjusting for race and body mass index (BMI), respectively. Body image discrepancy was moderately correlated with CV fitness (r = -.55, p < .001). After adjusting for demographics, percent body fat, but not CV fitness or MVPA, influenced body

Marginal discrepancy severely affects the long term success of All ceramic complete veneer crowns. The precise role of resin luting agents influencing this phenomenon needs to be explored further. To estimate and compare the marginal discrepancy in CAD/CAM processed All ceramic complete veneer crowns prior and following luting with resin bonded luting agents. Extracted human maxillary first premolars were randomly allocated into four groups of 27 samples each Viz., Group I-Resin Modified Glass Ionomer Cement (GIC) (RelyX), Group II-Bis-GMA based dual cure resin cement (Variolink II), Group III-PMMA based resin cement (Superbond), Group IV- Urethane Dimethacrylate resin cement (Calibra). Following tooth preparation, CAD/CAM All ceramic complete veneer crowns were fabricated and sectioned and marginal discrepancy was evaluated using a scanning electron microscope (TESCAN, Magnification power-1,00,000x) prior and after luting with the experimental resin cements. The vertical and horizontal discrepancy before and after cementation with Group I [270.08±103.10μm, 165.3±53.00μm and 270.86±102.70μm, 166.62±54.96μm respectively]; Group II [254.21±79.20μm, 117.75±24.29μm and 234.81±79μm, 116.89±18.22μm respectively]; Group III [272.47±86.25μm, 142.08±50.83μm and 251.82±62.69μm, 136.07±44.95μm respectively]; Group IV were [260.28±64.81μm, 116.98±17.71μm and 233.08±69.44μm, 116.58±21.13μm respectively]. ANOVA inferred a statistically significant difference between the four test specimen with regards to vertical and horizontal marginal discrepancy after cementation (F=9.092, p<0.001), (F=10.97, p<0.001). Tukey HSD Post-hoc test observed significant differences in vertical and horizontal marginal discrepancies between the resin modified glass ionomer and resin cements (p<0.05). Resin cements exhibited a greater reduction in the marginal discrepancy than the resin modified glass ionomer following luting in All ceramic complete veneer crowns. Hence

Reliability of Beta angle in assessing true anteroposterior apical base discrepancy in different growth patterns

PubMed Central

Sundareswaran, Shobha; Kumar, Vinay

2015-01-01

Introduction: Beta angle as a skeletal anteroposterior dysplasia indicator is known to be useful in evaluating normodivergent growth patterns. Hence, we compared and verified the accuracy of Beta angle in predicting sagittal jaw discrepancy among subjects with hyperdivergent, hypodivergent and normodivergent growth patterns. Materials and Methods: Lateral cephalometric radiographs of 179 patients belonging to skeletal Classes I, II, and III were further divided into normodivergent, hyperdivergent, and hypodivergent groups based on their vertical growth patterns. Sagittal dysplasia indicators - angle ANB, Wits appraisal, and Beta angle values were measured and tabulated. The perpendicular point of intersection on line CB (Condylion-Point B) in Beta angle was designated as ‘X’ and linear dimension XB was evaluated. Results: Statistically significant increase was observed in the mean values of Beta angle and XB distance in the vertical growth pattern groups of both skeletal Class I and Class II patients thus pushing them toward Class III and Class I, respectively. Conclusions: Beta angle is a reliable indicator of sagittal dysplasia in normal and horizontal patterns of growth. However, vertical growth patterns significantly increased Beta angle values, thus affecting their reliability as a sagittal discrepancy assessment tool. Hence, Beta angle may not be a valid tool for assessment of sagittal jaw discrepancy in patients exhibiting vertical growth patterns with skeletal Class I and Class II malocclusions. Nevertheless, Class III malocclusions having the highest Beta angle values were unaffected. PMID:25810649

Beyond general behavioral theories: structural discrepancy in young motorcyclist's risky driving behavior and its policy implications.

PubMed

Chung, Yi-Shih; Wong, Jinn-Tsai

2012-11-01

While many studies examine the mean score differences of psychological determinants between heterogeneous driver groups, this study reveals a structural discrepancy in a causal behavioral framework. Using young motorcyclists (ages 18-28) as subjects, this study investigates the various roles of key influential factors in determining risky driving behavior. Multi-group analysis of structural equation modeling shows that age and gender are two factors that can effectively distinguish heterogeneous driver groups exhibiting different decision-making mechanisms in shaping their risky driving behaviors. When encountering undesirable traffic conditions, road rage can immediately increase male motorcyclists' intentions to engage in risky driving behaviors; on the other hand, young female motorcyclists further calculate their perceived risk to determine whether to engage in risky driving behaviors. This result shows that there is a significant link between risk perception and traffic condition awareness for experienced drivers (ages 25-28), but not for younger drivers (ages 18-24). This finding shows that while well-developed theories such as planned behavior and risk homeostasis provide general frameworks to explain risky driving behavior, heterogeneous driver groups may exhibit structural discrepancies that reflect their various decision-making mechanisms. This suggests that, in addition to mean differences, understanding structural discrepancies among heterogeneous groups could help researchers identify effective intervention strategies.

What Students Think They Feel Differs from What They Really Feel – Academic Self-Concept Moderates the Discrepancy between Students’ Trait and State Emotional Self-Reports

PubMed Central

Bieg, Madeleine; Goetz, Thomas; Lipnevich, Anastasiya A.

2014-01-01

This study investigated whether there is a discrepancy pertaining to trait and state academic emotions and whether self-concept of ability moderates this discrepancy. A total of 225 secondary school students from two different countries enrolled in grades 8 and 11 (German sample; n = 94) and grade 9 (Swiss sample; n = 131) participated. Students’ trait academic emotions of enjoyment, pride, anger, and anxiety in mathematics were assessed with a self-report questionnaire, whereas to assess their state academic emotions experience-sampling method was employed. The results revealed that students’ scores on the trait assessment of emotions were generally higher than their scores on the state assessment. Further, as expected, students’ academic self-concept in the domain of mathematics was shown to partly explain the discrepancy between scores on trait and state emotions. Our results indicate that there is a belief-driven discrepancy between what students think they feel (trait assessment) and what they really feel (state assessment). Implications with regard to the assessment of self-reported emotions in future studies and practical implications for the school context are discussed. PMID:24647760

Subjective-Objective Sleep Discrepancy Is Associated With Alterations in Regional Glucose Metabolism in Patients With Insomnia and Good Sleeper Controls.

2017-11-01

Sleep discrepancies are common in primary insomnia (PI) and include reports of longer sleep onset latency (SOL) than measured by polysomnography (PSG) or "negative SOL discrepancy." We hypothesized that negative SOL discrepancy in PI would be associated with higher relative glucose metabolism during nonrapid eye movement (NREM) sleep in brain networks involved in conscious awareness, including the salience, left executive control, and default mode networks. PI (n = 32) and good sleeper controls (GS; n = 30) completed [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) scans during NREM sleep, and relative regional cerebral metabolic rate for glucose (rCMRglc) was measured. Sleep discrepancy was calculated by subtracting PSG-measured SOL on the PET night from corresponding self-report values the following morning. We tested for interactions between group (PI vs. GS) and SOL discrepancy for rCMRglc during NREM sleep using both a region of interest mask and exploratory whole-brain analyses. Significant group by SOL discrepancy interactions for rCMRglc were observed in several brain regions (pcorrected < .05 for all clusters). In the PI group, more negative SOL discrepancy (self-reported > PSG-measured SOL) was associated with significantly higher relative rCMRglc in the right anterior insula and middle/posterior cingulate during NREM sleep. In GS, more positive SOL discrepancy (self-reported < PSG-measured SOL) was associated with significantly higher relative rCMRglc in the right anterior insula, left anterior cingulate cortex, and middle/posterior cingulate cortex. Although preliminary, these findings suggest regions of the brain previously shown to be involved in conscious awareness, and the perception of PSG-defined states may also be involved in the phenomena of SOL discrepancy. © Sleep Research Society 2017.

Application of new WAIS-III/WMS-III discrepancy scores for evaluating memory functioning: relationship between intellectual and memory ability.

PubMed

Lange, Rael T; Chelune, Gordon J

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.

An emerging literature suggests that not only do parent and child perceptions of parent-child relationship quality independently predict children's adjustment, but also that the discrepancy between parent and child perceptions of the relationship also carries predictive power. In the current study, we examine discrepancies in mother and children's we-talk, which is thought to reveal the degree to which members of a dyad conceive of problems affecting just one of the members as shared. We anticipate that discrepancies in which the mother expresses a greater sense of we-ness than the child would be particularly toxic during this developmental phase, when youth's strivings for independence ought to near their apex. Using an ethnically and socioeconomically diverse sample of school-aged children and their mothers (N = 106, 49.1 % female; 43 % Non-Hispanic White, 21 % African American, 21 % Hispanic, 10 % Asian, and 5 % of another ethnic category or mixed race; 48 % reported an annual income of <$60,000), we expose children to a standardized failure task that their mothers observe and then interview both members of the dyad regarding the task-we-talk is derived from these interviews. We examine the discrepancy between child and mother we-talk as a predictor of children's cortisol reactivity and mothers' behavioral overcontrol during the failure task. We also examine whether the discrepancy in mother-child we-talk predicts children's trait rumination. The interaction between child and mother we-talk was significantly associated with all three outcomes. Children's cortisol reactivity and rumination were highest when mothers used high and children used low levels of we-talk. A three-way interaction of children's we-talk, mothers' we-talk and child age emerged, suggesting that the association of discrepancies in we-talk with maternal overcontrol depended on child age, with significant effects emerging among older children. We discuss our results in terms of their

The purpose of this study was to quantitatively evaluate the effects of experimental leg length discrepancies on body posture and dental occlusion. Thirty asymptomatic subjects (15 males and 15 females, ages 19-33, mean age 25.6 years) were included in this study and randomly assigned to one of two groups based on a table of random numbers. The only difference between group A and group B was the sequence of testing. Experimental leg length discrepancies were provided by using ten types of insoles with heights ranging from one to ten mm at one mm intervals, placed under both feet. The MatScan (Nitta Corp., Osaka, Japan) system was used to measure changes in body posture (center of foot pressure: COP) while subjects maintained the following three postural positions: 1. natural standing posture (control); 2. control with a heel lift under the right foot; or 3. control with a heel lift under the left foot. The T-Scan II system (Nitta Corp., Osaka, Japan) was used to analyze the results of changes in dental occlusion (center of occlusal force: COF) in the above-mentioned three postural positions. When subjects used a heel lift of six mm or more under the right foot, lateral weight distribution (LWD) shifted to the right side compared to the control (p<0.05). When a heel lift of four mm or more was used under the left foot, LWD shifted to the left side compared to the control (p<0.05). When subjects used a heel lift of eight mm or more under the right foot, occlusal force shifted to the right side compared to the control (p<0.05). When subjects used a heel lift of seven mm or more under the left foot, occlusal force shifted to the left side compared to the control (p<0.05). Based on these findings, it was concluded that leg length discrepancy affected body posture and dental occlusion.

Discrepancies between self and observer ratings of depression. The relationship to demographic, clinical and personality variables.

2000-10-01

The observer-rated Hamilton depression scale (HamD) and the self-report Beck Depression Inventory (BDI) are among the most commonly used rating scales for depression, and both have well demonstrated reliability and validity. However, many depressed subjects have discrepant scores on these two assessment methods. The present study evaluated the ability of demographic, clinical and personality factors to account for the discrepancies observed between BDI and HamD ratings. The study group consisted of 94 SCID-diagnosed outpatients with a current major depressive disorder. Subjects were rated with the 21-item HamD and completed the BDI and the NEO-Five Factor Inventory. Younger age, higher educational attainment, and depressive subtype (atypical, non-melancholic) were predictive of higher BDI scores relative to HamD observer ratings. In addition, high neuroticism, low extraversion and low agreeableness were associated with higher endorsement of depressive symptoms on the BDI relative to the HamD. In general, these predictive variables showed a greater ability to explain discrepancies between self and observer ratings of psychological symptoms of depression compared to somatic symptoms of depression. The study does not determine which aspects of neuroticism and extraversion contribute to the observed BDI/HamD discrepancies. Depression ratings obtained with the BDI and HamD are frequently discordant and a number of patient characteristics robustly predict the discrepancy between these two rating methods. The value of multi-modal assessment in the conduct of research on depressive disorders is re-affirmed.

The fission fragment yield distribution has been measured in the 239Pu(nth,f ) reaction in the mass region of A =126 to 150 using the Lohengrin recoil-mass spectrometer. Three independent experimental campaigns were performed, allowing a significant reduction of the uncertainties compared to evaluated nuclear data libraries. The long-standing discrepancy of around 10% for the relative yield of A =134 reported in JEF-2.2 and JEFF-3.1.1 data libraries is finally solved. Moreover, the measured mass distribution in thermal neutron-induced fission does not show any significant dip around the shell closure (A =136 ) as seen in heavy-ion fission data of 208Pb(18O, f ) and 238U(18O, f ) reactions. Lastly, comparisons between our experimental data and the predictions from Monte Carlo codes (gef and fifrelin) are presented and discussed.

Self-discrepancy and regulatory fit in avatar-based exergames.

PubMed

Jin, Seung-A Annie

2012-12-01

Drawing from Higgins's self-discrepancy theory and regulatory focus theory, this study examined the use of activated selves and regulatory foci in health games. Utilizing the Wii's avatar-creating and exergaming features, a 2 (activated self: actual self versus ideal self) x 2 (regulatory focus: promotion versus prevention) x 2 (efficacy appeals: self-efficacy versus response-efficacy) between-subjects experiment tested the interactions of activated selves, regulatory foci, and efficacy appeals on low-calorie dieting intentions after health game playing. Results from an experiment with 156 participants demonstrated that a fit between regulatory focus and efficacy appeals induced greater dieting intentions when the actual self was activated while the opposite effect occurred when the ideal self was activated. Theoretical contributions to basic and applied social psychology as well as managerial implications for consumer behavior research are considered.

The discrepancy between risky and riskless utilities: a matter of framing?

PubMed

Stalmeier, P F; Bezembinder, T G

1999-01-01

Utilities differ according to whether they are derived from risky (gamble) and riskless (visual analog scale, time-tradeoff) assessment methods. The discrepancies are usually explained by assuming that the utilities elicited by risky methods incorporate attitudes towards risk, whereas riskless utilities do not. In (cumulative) prospect theory, risk attitude is conceived as consisting of two components: a decision-weight function (attentiveness to changes in, or sensitivity towards, chance) and a utility function (sensitivity towards outcomes). The authors' data suggest that a framing effect is a hitherto unrecognized and important factor in causing discrepancies between risky and riskless utilities. They collected risky evaluations with the gamble method, and riskless evaluations with difference measurement. Risky utilities were derived using expected-utility theory and prospect theory. With the latter approach, sensitivity towards outcomes and sensitivity towards chance are modeled separately. When the hypothesis that risky utilities from prospect theory coincide with riskless utilities was tested, it was rejected (n = 8, F(1,7) = 132, p = 0.000), suggesting that a correction for sensitivity towards chance is not sufficient to resolve the difference between risky and riskless utilities. Next, it was assumed that different gain/loss frames are induced by risky and riskless elicitation methods. Indeed, identical utility functions were obtained when the gain/loss frames were made identical across methods (n = 7), suggesting that framing was operative. The results suggest that risky and riskless utilities are identical after corrections for sensitivity towards chance and framing.

Discrepancies between patients' and partners' perceptions of unsupportive behavior in chronic obstructive pulmonary disease.

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.

Two-Player Partnered Exergame for Obesity Prevention: Using Discrepancy in Players’ Abilities as a Strategy to Motivate Physical Activity

PubMed Central

Feltz, Deborah L.; Irwin, Brandon; Kerr, Norbert

2012-01-01

Background 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. Method 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. Results 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

Comparison of Anaerobic Susceptibility Results Obtained by Different Methods

1979-01-01

Susceptibility tests using 7 antimicrobial agents (carbenicillin, chloramphenicol, clindamycin, penicillin, cephalothin, metronidazole, and tetracycline) were run against 35 anaerobes including Bacteroides fragilis (17), other gram-negative bacilli (7), clostridia (5), peptococci (4), and eubacteria (2). Results in triplicate obtained by the microbroth dilution method and the aerobic modification of the broth disk method were compared with those obtained with an agar dilution method using Wilkins-Chalgren agar. Media used in the microbroth dilution method included Wilkins-Chalgren broth, brain heart infusion broth, brucella broth, tryptic soy broth, thioglycolate broth, and Schaedler's broth. A result differing by more than one dilution from the Wilkins-Chalgren agar result was considered a discrepancy, and when there was a change in susceptibility status this was termed a significant discrepancy. The microbroth dilution method using Wilkins-Chalgren broth and thioglycolate broth produced the fewest total discrepancies (22 and 24, respectively), and Wilkins-Chalgren broth, thioglycolate, and Schaedler's broth had the fewest significant discrepancies (6, 5, and 5, respectively). With the broth disk method, there were 15 significant discrepancies, although half of these were with tetracycline, which was the antimicrobial agent associated with the highest number of significant discrepancies (33), considering all of the test methods and media.

Resolving Discrepancies Between Observed and Predicted Dynamic Topography on Earth

NASA Astrophysics Data System (ADS)

Richards, F. D.; Hoggard, M.; White, N. J.

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

Quasirandom geometric networks from low-discrepancy sequences

NASA Astrophysics Data System (ADS)

Estrada, Ernesto

2017-08-01

We define quasirandom geometric networks using low-discrepancy sequences, such as Halton, Sobol, and Niederreiter. The networks are built in d dimensions by considering the d -tuples of digits generated by these sequences as the coordinates of the vertices of the networks in a d -dimensional Id unit hypercube. Then, two vertices are connected by an edge if they are at a distance smaller than a connection radius. We investigate computationally 11 network-theoretic properties of two-dimensional quasirandom networks and compare them with analogous random geometric networks. We also study their degree distribution and their spectral density distributions. We conclude from this intensive computational study that in terms of the uniformity of the distribution of the vertices in the unit square, the quasirandom networks look more random than the random geometric networks. We include an analysis of potential strategies for generating higher-dimensional quasirandom networks, where it is know that some of the low-discrepancy sequences are highly correlated. In this respect, we conclude that up to dimension 20, the use of scrambling, skipping and leaping strategies generate quasirandom networks with the desired properties of uniformity. Finally, we consider a diffusive process taking place on the nodes and edges of the quasirandom and random geometric graphs. We show that the diffusion time is shorter in the quasirandom graphs as a consequence of their larger structural homogeneity. In the random geometric graphs the diffusion produces clusters of concentration that make the process more slow. Such clusters are a direct consequence of the heterogeneous and irregular distribution of the nodes in the unit square in which the generation of random geometric graphs is based on.

this observational study aimed to describe the discrepancies identified during medication reconciliation on patient admission to cardiology units in a large hospital. the medication history of patients was collected within 48 hours after admission, and intentional and unintentional discrepancies were classified as omission, duplication, dose, frequency, timing, and route of drug administration. most of the patients evaluated were women (58.0%) with a mean age of 59 years, and 75.5% of the patients had a Charlson comorbidity index score between 1 and 3. Of the 117 discrepancies found, 50.4% were unintentional. Of these, 61.0% involved omission, 18.6% involved dosage, 18.6% involved timing, and 1.7% involved the route of drug administration. this study revealed a high prevalence of discrepancies, most of which were related to omissions, and 50% were unintentional. These results reveal the number of drugs that are not reincorporated into the treatment of patients, which can have important clinical consequences. este estudo observacional teve como objetivo descrever discrepâncias encontradas na realização de conciliação medicamentosa de pacientes admitidos em unidades de cardiologia de um hospital de grande porte. a história de medicação dos pacientes foi coletada dentro de 48h após a admissão, e as discrepâncias, identificadas como intencionais ou não intencionais, foram classificadas como de: omissão, duplicidade, dose, frequência, intervalo e via. a maioria dos pacientes incluídos pertençia ao sexo feminino (58,0%), com idade média de 59 anos, e com índice de comorbidades de Charlson entre 1 e 3 (75,5% dos casos).

Objective To assess surgical team members’ differences in perception of non-technical skills. Design Questionnaire design. Setting Operating theatres (OTs) at one university hospital, three teaching hospitals and one general hospital in the Netherlands. Participants Sixty-six surgeons, 97 OT nurses, 18 anaesthetists and 40 nurse anaesthetists. Methods All surgical team members, of five hospitals, were asked to complete a questionnaire and state their opinion on the current state of communication, teamwork and situation awareness at the OT. Results Ratings for ‘communication’ were significantly different, particularly between surgeons and all other team members (P ≤ 0.001). The ratings for ‘teamwork’ differed significantly between all team members (P ≤ 0.005). Within ‘situation awareness’ significant differences were mainly observed for ‘gathering information’ between surgeons and other team members (P < 0.001). Finally, 72–90% of anaesthetists, OT nurses and nurse anaesthetists rated routine team briefings and debriefings as inadequate. Conclusions This study shows discrepancies on many aspects in perception between surgeons and other surgical team members concerning communication, teamwork and situation awareness. Future research needs to ascertain whether these discrepancies are linked to greater risk of adverse events or to process as well as systems failures. Establishing this link would support implementation and use of complex team interventions that intervene at multiple levels of the healthcare system. PMID:21242160

Management of organ donors in the intensive care unit is an emerging subject in critical care and transplantation. This study evaluates organ yield outcomes for a large number of patients managed by the Indiana Organ Procurement Organization. This is a retrospective review of intensive care unit records from 2008-2012. Donor demographic information and seven donor management parameters (DMP) were recorded at admission, consent, 12 h after consent, and before procurement. Three study groups were created: donors meeting 0-3, 4, or 5-7 DMP. Active donor Organ Procurement Organization management began at consent; so, data analysis focuses on the 12-h postconsent time point. Outcomes included organs transplanted per donor (OTPD) and transplantation of individual solid organs. Complete records for 499 patients were reviewed. Organ yield was 1415 organs of 3992 possible (35%). At 12 h, donors meeting more DMP had more OTPD: 2.2 (0-3) versus 3.0 (4) versus 3.5 (5-7) (P < 0.01). Aggregate DMP met was significantly associated with transplantation of every organ except intestine. Oxygen tension, vasopressor use, and central venous pressure were the most frequent independent predictors of organ usage. There were significantly more organs transplanted for donors meeting all three of these parameters (4.5 versus 2.7, P < 0.01). Initial DMP met does not appear to be a significant prognostic factor for OTPD. Aggregate DMP is associated with transplantation rates for most organs, with analysis of individual parameters suggesting that appropriate management of oxygenation, volume status, and vasopressor use could lead to more organs procured per donor.

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.

A probable stellar solution to the cosmological lithium discrepancy.

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.

Relationship and significance of gait deviations associated with limb length discrepancy: A systematic review.

Khamis, Sam; Carmeli, Eli

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.

2009-01-01

Prior work has not tested the basic theoretical notion that informant discrepancies in reports of children's behavior exist, in part, because different informants observe children's behavior in different settings. We examined patterns of observed preschool disruptive behavior across varying social contexts in the laboratory and whether they…

Enhancing DSN Operations Efficiency with the Discrepancy Reporting Management System (DRMS)

NASA Technical Reports Server (NTRS)

Chatillon, Mark; Lin, James; Cooper, Tonja M.

2003-01-01

The DRMS is the Discrepancy Reporting Management System used by the Deep Space Network (DSN). It uses a web interface and is a management tool designed to track and manage: data outage incidents during spacecraft tracks against equipment and software known as DRs (discrepancy Reports), to record "out of pass" incident logs against equipment and software in a Station Log, to record instances where equipment has be restarted or reset as Reset records, and to electronically record equipment readiness status across the DSN. Tracking and managing these items increases DSN operational efficiency by providing: the ability to establish the operational history of equipment items, data on the quality of service provided to the DSN customers, the ability to measure service performance, early insight into processes, procedures and interfaces that may need updating or changing, and the capability to trace a data outage to a software or hardware change. The items listed above help the DSN to focus resources on areas of most need.

Affective Evaluations of Exercising: The Role of Automatic-Reflective Evaluation Discrepancy.

PubMed

Brand, Ralf; Antoniewicz, Franziska

2016-12-01

Sometimes our automatic evaluations do not correspond well with those we can reflect on and articulate. We present a novel approach to the assessment of automatic and reflective affective evaluations of exercising. Based on the assumptions of the associative-propositional processes in evaluation model, we measured participants' automatic evaluations of exercise and then shared this information with them, asked them to reflect on it and rate eventual discrepancy between their reflective evaluation and the assessment of their automatic evaluation. We found that mismatch between self-reported ideal exercise frequency and actual exercise frequency over the previous 14 weeks could be regressed on the discrepancy between a relatively negative automatic and a more positive reflective evaluation. This study illustrates the potential of a dual-process approach to the measurement of evaluative responses and suggests that mistrusting one's negative spontaneous reaction to exercise and asserting a very positive reflective evaluation instead leads to the adoption of inflated exercise goals.

Parent-child acculturation discrepancy is a risk factor in the development of children in immigrant families. Using a longitudinal sample of Chinese immigrant families, the authors of the current study examined how unsupportive parenting and parent-child sense of alienation sequentially mediate the relationship between parent-child acculturation discrepancy and child adjustment during early and middle adolescence. Acculturation discrepancy scores were created using multilevel modeling to take into account the interdependence among family members. Structural equation models showed that during early adolescence, parent-child American orientation discrepancy is related to parents' use of unsupportive parenting practices; parents' use of unsupportive parenting is related to increased sense of alienation between parents and children, which in turn is related to more depressive symptoms and lower academic performance in Chinese American adolescents. These patterns of negative adjustment established in early adolescence persist into middle adolescence. This mediating effect is more apparent among father-adolescent dyads than among mother-adolescent dyads. In contrast, parent-child Chinese orientation discrepancy does not demonstrate a significant direct or indirect effect on adolescent adjustment, either concurrently or longitudinally. The current findings suggest that during early adolescence, children are more susceptible to the negative effects of parent-child acculturation discrepancy; they also underscore the importance of fathering in Chinese immigrant families.

Mountainous regions are increasingly vulnerable to food insecurity because of limited arable land, growing population pressure, and climate change. Development of sustainable mountain agriculture will require an increased understanding of the effects of environmental factors on grain and climatic yields. The objective of this study was to explore the relationships between actual grain yield, climatic yield, and environmental factors in a mountainous region in China. We collected data on the average grain yield per unit area in 119 counties in Yunnan province from 1985 to 2012, and chose 17 environmental factors for the same period. Our results showed that actual grain yield ranged from 1.43 to 6.92 t·ha-1, and the climatic yield ranged from -0.15 to -0.01 t·ha-1. Lower climatic yield but higher grain yield was generally found in central areas and at lower slopes and elevations in the western and southwestern counties of Yunnan province. Higher climatic yield but lower grain yield were found in northwestern parts of Yunnan province on steep slopes. Annual precipation and temperature had a weak influence on the climatic yield. Slope explained 44.62 and 26.29% of the variation in grain yield and climatic yield. The effects of topography on grain and climatic yields were greater than climatic factors. Slope was the most important environmental variable for the variability in climatic and grain yields in the mountainous Yunnan province due to the highly heterogeneous topographic conditions. Conversion of slopes to terraces in areas with higher climatic yields is an effective way to maintain grain production in response to climate variability. Additionally, soil amendments and soil and water conservation measures should be considered to maintain soil fertility and aid in sustainable development in central areas, and in counties at lower slopes and elevations in western and southwestern Yunnan province.

Marginal discrepancies of zirconia posterior fixed dental prostheses (FDPs) fabricated using various systems have been assessed to determine the quality of the restorations and facilitate clinical use; however, studies are limited and results are ambiguous because of the sample sizes and measurement methods. The purpose of this in vitro study was to compare changes in marginal fit of posterior fixed dental prostheses of 3 zirconia systems manufactured using CAD/CAM technology and metal ceramic posterior fixed dental protheses fabricated with the conventional lost-wax technique, before and after cementation. Forty standardized master steel dies with 2 abutments simulating first mandibular premolars were fabricated to receive a posterior 3-unit FDP (from first molar to first premolar) and divided into 4 groups (n=10): Lava All-Ceramic System, Procera Bridge Zirconia, VITA In-Ceram 2000 YZ, and metal ceramic (control group). All FDPs were prepared for an internal space of 50 microm. The external marginal gap of the restorations was investigated by measuring 30 points in the middle of the buccal and lingual surfaces; therefore, 60 measurements per abutment were recorded. Measurements were made with an image analysis program on the master steel model before and after conventional cementation with a glass ionomer agent (Ketac Cem Easymix). The data obtained were statistically analyzed using 1-way ANOVA, Duncan's multiple range post hoc test, and Student's paired t test (alpha=.05). No significant differences in the vertical marginal fit before and after cementation were recorded for the analyzed groups. The marginal discrepancy of Procera abutments before and after cementation (9 +/-10 microm and 12 +/-9 microm, respectively) was less than that of the other groups. Significant differences (P=.001) were observed in marginal adaptation between Procera Bridge Zirconia and the other groups. The results of this study showed that cementation did not cause a significant

Inflow, Outflow, Yields, and Stellar Population Mixing in Chemical Evolution Models

Andrews, Brett H.; Weinberg, David H.; Schönrich, Ralph; Johnson, Jennifer A.

2017-02-01

Chemical evolution models are powerful tools for interpreting stellar abundance surveys and understanding galaxy evolution. However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar initial mass function, the SN Ia delay time distribution, stellar yields, and stellar population mixing. Using flexCE, a flexible one-zone chemical evolution code, we investigate the effects of and trade-offs between parameters. Two critical parameters are SFE and the outflow mass-loading parameter, which shift the knee in [O/Fe]-[Fe/H] and the equilibrium abundances that the simulations asymptotically approach, respectively. One-zone models with simple star formation histories follow narrow tracks in [O/Fe]-[Fe/H] unlike the observed bimodality (separate high-α and low-α sequences) in this plane. A mix of one-zone models with inflow timescale and outflow mass-loading parameter variations, motivated by the inside-out galaxy formation scenario with radial mixing, reproduces the two sequences better than a one-zone model with two infall epochs. We present [X/Fe]-[Fe/H] tracks for 20 elements assuming three different supernova yield models and find some significant discrepancies with solar neighborhood observations, especially for elements with strongly metallicity-dependent yields. We apply principal component abundance analysis to the simulations and existing data to reveal the main correlations among abundances and quantify their contributions to variation in abundance space. For the stellar population mixing scenario, the abundances of α-elements and elements with metallicity-dependent yields dominate the first and second principal components, respectively, and collectively explain 99% of the variance in the model. flexCE is a python package available at https://github.com/bretthandrews/flexCE.

Although patients with medullary thyroid cancer are known to present with paraneoplastic hormone production, this is much less common with papillary thyroid cancer. We present a patient with the cribriform morular variant of papillary thyroid cancer in association with familial adenomatous polyposis who developed a positive pregnancy test in the absence of known pregnancy. The patient had developed vaginal bleeding, and her laboratory testing was characterized by elevated serum human chorionic gonadotropin (β-hCG) concentrations, but negative qualitative urine results. After a thorough gynecological evaluation to exclude unexpected normal, ectopic, or molar pregnancy, we pursued an evaluation for other sources of β-hCG production. We showed that the elevated serum β-hCG concentrations were not the result of heterophile antibody interferences, and ultimately we proved that her recurrent tumor produced the ectopic β-hCG. This is the first report of β-hCG production by papillary thyroid cancer. Thus, the possibility of ectopic production of β-hCG by papillary thyroid cancer needs to be included in the differential diagnosis of elevated hCG concentration in the absence of pregnancy. This study of an unusual paraneoplastic syndrome highlights the importance of investigating discrepancies in the clinical laboratory. Copyright © 2014 Elsevier B.V. All rights reserved.

Discrepant feeling rules and unscripted emotion work: women coping with termination for fetal anomaly.

PubMed

McCoyd, Judith L M

2009-10-01

The sociology of emotion is rapidly evolving and has implications for medical settings. Advancing medical technologies create new contexts for decision-making and emotional reaction that are framed by "feeling rules." Feeling rules guide not only behavior, but also how one believes one should feel, thereby causing one to attempt to bring one's authentic feelings into line with perceived feeling rules. Using qualitative data, the theoretical existence of feeling rules in pregnancy and prenatal testing is confirmed. Further examination extends this analysis: at times of technological development feeling rules are often discrepant, leaving patients with unscripted emotion work. Data from a study of women who interrupted anomalous pregnancies indicate that feeling rules are unclear when competing feeling rules are operating during times of societal and technological change. Because much of this occurs below the level of consciousness, medical and psychological services providers need to be aware of potential discrepancies in feeling rules and assist patients in identifying the salient feeling rules. Patients' struggles ease when they can recognize the discrepancies and assess their implications for decision-making and emotional response. (c) 2009 APA, all rights reserved.

2009-06-01

The authors conducted a study with 500 parent-child dyads. The sample comprised 254 boys and 246 girls. The children were grouped into 5 age groups (1 group for each age from 7 to 11 years), with each group comprising 100 children. The survey regards discrepancies between children and their parents on attitudes toward TV advertising to determine how TV commercials affect children's developmental stages and, particularly, their credence, behavioral intentions, and TV enjoyment. Regarding enjoyment and purchase dimensions, the group of 7-year-old children claimed that they enjoyed and are influenced in their consumer attitude more than did the groups of 8-11-year-old children. Credence decreased significantly with age. This study showed that parents tended to undervalue TV advertising's influence on their children. Parents' conformity was a significant predictor of children's attitude toward TV advertising. Results indicated that a high level of parental conformity was linked to the number of brands children claimed to possess.

Background Home smoking bans significantly reduce the likelihood of secondhand smoke exposure among children and non-smoking adults. The purpose of this study was to examine national trends in a) the adoption of home smoking bans; b) discrepancies in parental smoking ban reports; and c) household and parental correlates of home smoking bans among households with underage children from 1995 to 2007. Methods We used data from the 1995/1996, 1998/1999, 2001/2002, 2003 and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey to estimate prevalence rates and logistic regression models of parental smoking ban reports by survey period. Results Overall, the prevalence of a complete home smoking bans increased from 58.1% to 83.8% (p<0.01), while discrepancies in parental reports decreased from 12.5% to 4.6% (p<0.01) from 1995 to 2007. Households with single parent, low income, one or two current smokers, parents with less than a college education, or without infants were consistently less likely to report a home smoking ban over this period (p<0.05). Conclusion Despite general improvements in the adoption of home smoking bans and a reduction on parental discrepancies, disparities in the level of protection from secondhand smoke have persisted over time. Children living in households with single parents, low income, current smoker parents, less educated parents, or without infants are less likely to be protected by a home smoking ban. These groups are in need of interventions promoting the adoption of home smoking bans to reduce disparities in tobacco-related diseases. PMID:21813487

Background and Objectives: In orthodontic diagnosis and treatment planning, assessment of anteroposterior discrepancy is of importance to the orthodontist. Both angular and linear measurements have been incorporated into various cephalometric analyses to help the clinician diagnose anteroposterior discrepancies and establish the most appropriate treatment plan. Hence the present study is designed to establish the norms of Beta angle to assess the sagittal discrepancy for Nellore district population. Materials and Methods: The sample was screened from the old records of the Orthodontic department of Narayana Dental College and Hospital. One hundred and fifty pretreatment cephalometric radiographs (50 each of Class I, II, and III) were subdivided based on ANB, Wits appraisal, and Beta angle into skeletal Class I, II, III. The same cephalograms were again classified into skeletal Class I, II, and III based purely on Beta angle. Each group was again divided into 2 subgroups consisting of 25 male and 25 female subjects with a mean age limit between 15 and 45 years old. Results: The Newman-keuls post hoc test and ANOVA showed that the 3 groups were significantly different (P ≤ 0.001). The Newman-keuls post hoc test also found the groups to be significantly different. Conclusions: There was statistically significant difference for, the mean values and the standard deviation for Beta angle within the three skeletal patterns (Class I, Class II and Class III skeletal patterns). There was no statistically significant difference among the mean values of beta angle between Nellore district population and Caucasian norms and between male and female sex groups. PMID:24082742

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 profiles may aid both

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.

Predicting paddlefish roe yields using an extension of the Beverton–Holt equilibrium yield-per-recruit model

Equilibrium yield models predict the total biomass removed from an exploited stock; however, traditional yield models must be modified to simulate roe yields because a linear relationship between age (or length) and mature ovary weight does not typically exist. We extended the traditional Beverton-Holt equilibrium yield model to predict roe yields of Paddlefish Polyodon spathula in Kentucky Lake, Tennessee-Kentucky, as a function of varying conditional fishing mortality rates (10-70%), conditional natural mortality rates (cm; 9% and 18%), and four minimum size limits ranging from 864 to 1,016mm eye-to-fork length. These results were then compared to a biomass-based yield assessment. Analysis of roe yields indicated the potential for growth overfishing at lower exploitation rates and smaller minimum length limits than were suggested by the biomass-based assessment. Patterns of biomass and roe yields in relation to exploitation rates were similar regardless of the simulated value of cm, thus indicating that the results were insensitive to changes in cm. Our results also suggested that higher minimum length limits would increase roe yield and reduce the potential for growth overfishing and recruitment overfishing at the simulated cm values. Biomass-based equilibrium yield assessments are commonly used to assess the effects of harvest on other caviar-based fisheries; however, our analysis demonstrates that such assessments likely underestimate the probability and severity of growth overfishing when roe is targeted. Therefore, equilibrium roe yield-per-recruit models should also be considered to guide the management process for caviar-producing fish species.

Adolescence is a critical period for the development of depressive symptoms. Lower quality of the parent-adolescent relationship has been consistently associated with higher adolescent depressive symptoms, but discrepancies in perceptions of parents and adolescents regarding the quality of their relationship may be particularly important to consider. In the present study, we therefore examined how discrepancies in parents' and adolescents' perceptions of the parent-adolescent relationship were associated with early adolescent depressive symptoms, both concurrently and longitudinally over a 1-year period. Our sample consisted of 497 Dutch adolescents (57 % boys, M age = 13.03 years), residing in the western and central regions of the Netherlands, and their mothers and fathers, who all completed several questionnaires on two occasions with a 1-year interval. Adolescents reported on depressive symptoms and all informants reported on levels of negative interaction in the parent-adolescent relationship. Results from polynomial regression analyses including interaction terms between informants' perceptions, which have recently been proposed as more valid tests of hypotheses involving informant discrepancies than difference scores, suggested the highest adolescent depressive symptoms when both the mother and the adolescent reported high negative interaction, and when the adolescent reported high but the father reported low negative interaction. This pattern of findings underscores the need for a more sophisticated methodology such as polynomial regression analysis including tests of moderation, rather than the use of difference scores, which can adequately address both congruence and discrepancies in perceptions of adolescents and mothers/fathers of the parent-adolescent relationship in detail. Such an analysis can contribute to a more comprehensive understanding of risk factors for early adolescent depressive symptoms.

2012-09-01

The aim of this study was to examine the associations between women's actual:ideal weight-related self-discrepancies and experiences of weight-related shame, guilt, and authentic pride using self-discrepancy (Higgins, 1987) and self-conscious emotion (Tracy & Robins, 2004) theories as guiding frameworks. Participants (N=398) completed self-report questionnaires. Main analyses involved polynomial regressions, followed by the computation and evaluation of response surface values. Actual and ideal weight self-states were related to shame (R2 = .35), guilt (R2 = .25), and authentic pride (R2 = .08). When the discrepancy between actual and ideal weights increased, shame and guilt also increased, while authentic pride decreased. Findings provide partial support for self-discrepancy theory and the process model of self-conscious emotions. Experiencing weight-related self-discrepancies may be important cognitive appraisals related to shame, guilt, and authentic pride. Further research is needed exploring the relations between self-discrepancies and a range of weight-related self-conscious emotions. Copyright © 2012 Elsevier Ltd. All rights reserved.

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. PMID:26368911

Economic barriers to implementation of innovations in health care: is the long run-short run efficiency discrepancy a paradox?

PubMed

Adang, Eddy M M; Wensing, Michel

2008-12-01

Favourable cost-effectiveness of innovative technologies is more and more a necessary condition for implementation in clinical practice. But proven cost-effectiveness itself does not guarantee successful implementation. The reason for this is a potential discrepancy between long run efficiency, on which cost-effectiveness is based, and short run efficiency. Long run and short run efficiency is dependent upon economies of scale. This paper addresses the potential discrepancy between long run and short run efficiency of innovative technologies in healthcare, explores diseconomies of scale in Dutch hospitals and suggests what strategies might help to overcome hurdles to implement innovations due to that discrepancy.

Actual-desired discrepancies in people's self-concepts represent structural incongruities in their self-representations that can lead people to experience subjective conflict. Theory and research suggest that structural incongruities predict susceptibility to subtle influences like priming and conditioning. Although typically examined for their motivational properties, we hypothesized that because self-discrepancies represent structural incongruities in people's self-concepts, they should also predict susceptibility to subtle influences on people's active self-views. Across three studies, we found that subtle change inductions (self-evaluative conditioning and priming) exerted greater impact on active self-perceptions and behavior as actual-desired self-discrepancies increased in magnitude. Exploratory analyses suggested that these changes occurred regardless of the compatibility of the change induction with individuals' desired self-views. © 2016 by the Society for Personality and Social Psychology, Inc.

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.

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.

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 (P<.05). Within the limitation of this in vitro study, all tested CAD-CAM systems produced monolithic zirconia restorations with clinically acceptable marginal discrepancies; however, the CAD-CAM system with the 5-axis milling unit produced the best marginal fit.

Discrepancy between mRNA and protein abundance: Insight from information retrieval process in computers

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.

Model simulations and proxy-based reconstructions are the main tools for quantifying pre-instrumental climate variations. For some metrics such as Northern Hemisphere mean temperatures, there is remarkable agreement between models and reconstructions. For other diagnostics, such as the regional response to volcanic eruptions, or hemispheric temperature differences, substantial disagreements between data and models have been reported. Here, we assess the potential sources of these discrepancies by comparing 1000-year hemispheric temperature reconstructions based on real-world paleoclimate proxies with climate-model-based pseudoproxies. These pseudoproxy experiments (PPE) indicate that noise inherent in proxy records and the unequal spatial distribution of proxy data are the key factors in explaining the data-model differences. For example, lower inter-hemispheric correlations in reconstructions can be fully accounted for by these factors in the PPE. Noise and data sampling also partly explain the reduced amplitude of the response to external forcing in reconstructions compared to models. For other metrics, such as inter-hemispheric differences, some, although reduced, discrepancy remains. Our results suggest that improving proxy data quality and spatial coverage is the key factor to increase the quality of future climate reconstructions, while the total number of proxy records and reconstruction methodology play a smaller role.

Pollock, Nira R.

2010-01-01

Purpose: To assess the frequency and spectrum of abnormalities on routine screening chest radiographs in the pre-employment evaluation of health care workers with positive tuberculin skin test (TST) results. Materials and Methods: The institutional review board approved this HIPAA-compliant retrospective study and waived the need for written informed patient consent. Chest radiographic reports of all 2586 asymptomatic individuals with positive TST results who underwent pre-employment evaluation between January 1, 2003, and December 31, 2007, were evaluated to determine the frequency of detection of evidence of active tuberculosis (TB) or latent TB infection (LTBI) and the spectrum of imaging findings. All chest radiographs interpreted as positive were reviewed by an experienced board-certified radiologist. If there was a discrepancy between the two readings, a second experienced radiologist served as an independent and final arbiter. Any follow-up chest radiographs or computed tomographic images that had been acquired by employee health services or by the employee’s private physician as a result of a suspected abnormality detected at initial screening were also evaluated. Results: Of the 159 (6.1%) chest radiographic examinations that yielded abnormal results, there were no findings that were consistent with active TB. There were 92 cases of calcified granulomas, calcified lymph nodes, or both; 25 cases of apical pleural thickening; 16 cases of fibrous scarring; and 31 cases of noncalcified nodules. All cases of fibrous scarring involved an area smaller than 2 cm2. All noncalcified nodules were 4 mm in diameter or smaller, with the exception of one primary lung malignancy and one necrotizing granuloma (negative for acid-fast bacilli) that grew Mycobacterium kansasii on culture. Conclusion: Universal chest radiography in a large pre-employment TB screening program was of low yield in the detection of active TB or increased LTBI reactivation risk, and it provided

Discrepancy between experimental and theoretical excitation transfer rates in LH2 bacteriochlorophyll-protein complexes of purple bacteria.

Discrepancy is revealed between the values of excitation transfer times measured experimentally, and those calculated, for the atomic structures of B800 --> B850 bacteriochlorophylls within the LH2 light-harvesting pigment-protein complex of the purple bacterium Rhodopseudomonas acidophila. The value 2.9-3.2 ps for the B800 --> B850 excitation transfer, calculated on the basis of atomic structure of LH2, is about 4-times longer than that measured for this bacterium (0.7 ps). This discrepancy appears common in at least two purple bacteria. Possible sources responsible for this discrepancy are discussed. It may either signify some drawback/s/ in our notions about the precise in vivo structure of LH2 complexes, for example, possible changes of LH2 structure during crystallization, or it may reflect our ignorance of some mechanisms involved in excitation migration.

Inflow, Outflow, Yields, and Stellar Population Mixing in Chemical Evolution Models

DOE Office of Scientific and Technical Information (OSTI.GOV)

Andrews, Brett H.; Weinberg, David H.; Schönrich, Ralph

Chemical evolution models are powerful tools for interpreting stellar abundance surveys and understanding galaxy evolution. However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar initial mass function, the SN Ia delay time distribution, stellar yields, and stellar population mixing. Using flexCE, a flexible one-zone chemical evolution code, we investigate the effects of and trade-offs between parameters. Two critical parameters are SFE and the outflow mass-loading parameter, which shift the knee in [O/Fe]–[Fe/H] and the equilibrium abundances that the simulations asymptotically approach, respectively. One-zone models with simple star formation histories follow narrow tracksmore » in [O/Fe]–[Fe/H] unlike the observed bimodality (separate high- α and low- α sequences) in this plane. A mix of one-zone models with inflow timescale and outflow mass-loading parameter variations, motivated by the inside-out galaxy formation scenario with radial mixing, reproduces the two sequences better than a one-zone model with two infall epochs. We present [X/Fe]–[Fe/H] tracks for 20 elements assuming three different supernova yield models and find some significant discrepancies with solar neighborhood observations, especially for elements with strongly metallicity-dependent yields. We apply principal component abundance analysis to the simulations and existing data to reveal the main correlations among abundances and quantify their contributions to variation in abundance space. For the stellar population mixing scenario, the abundances of α -elements and elements with metallicity-dependent yields dominate the first and second principal components, respectively, and collectively explain 99% of the variance in the model. flexCE is a python package available at https://github.com/bretthandrews/flexCE.« less

To determine the influence of maxillary posterior discrepancy on upper molar vertical position and dentofacial vertical dimensions in individuals with or without skeletal open bite (SOB). Pre-treatment lateral cephalograms of 139 young adults were examined. The sample was divided into eight groups categorized according to their sagittal and vertical skeletal facial growth pattern and maxillary posterior discrepancy (present or absent). Upper molar vertical position, overbite, lower anterior facial height and facial height ratio were measured. Independent t-test was performed to determine differences between the groups considering maxillary posterior discrepancy. Principal component analysis and MANCOVA test were also used. No statistically significant differences were found comparing the molar vertical position according to maxillary posterior discrepancy for the SOB Class I group or the group with adequate overbite. Significant differences were found in SOB Class II and Class III groups. In addition, an increased molar vertical position was found in the group without posterior discrepancy. Some variables closely related with the individual's intrinsic craniofacial development that could influence the evaluated vertical measurements were not considered. Overall maxillary posterior discrepancy does not appear to have a clear impact on upper molar vertical position or facial vertical dimensions. Only the SOB Class III group without posterior discrepancy had a significant increased upper molar vertical position. © The Author 2015.

Two-player partnered exergame for obesity prevention: using discrepancy in players' abilities as a strategy to motivate physical activity.

Feltz, Deborah L; Irwin, Brandon; Kerr, Norbert

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).

Although legally anchored, there are no empirical results from German second opinion programs. In this study, various aspects within a population of a second opinion program are examined. In this study patients were analyzed who sought a second opinion in the period from August 2011 to December 2016. Differences in patient characteristics, differentiated by agreement of first and second opinion, were analyzed using multivariate logistic regression. Patients' satisfaction and quality of life were examined one, three and six months after obtaining the second opinion. In total, 1,414 patients sought a second opinion. Most frequent medical indications were the knee (38.7 %), the back (26.8 %), the hip (11.7 %), and the shoulder (10.2 %). Except for the indication (p=0.035), no patient characteristic had influence on the conformation of the second opinion. Approximately two out of three initial recommendations were not confirmed by the specialists. 89 % of the patients were satisfied or very satisfied with the second opinion and the service offered. The second opinion offers patients the opportunity to seek an additional independent medical opinion and thus provide support for decision making. Further research is needed to examine the reasons for the high discrepancies between the first and second opinions. Copyright © 2018. Published by Elsevier GmbH.

Large sample area and size are needed for forest soil seed bank studies to ensure low discrepancy with standing vegetation.

A large number of small-sized samples invariably shows that woody species are absent from forest soil seed banks, leading to a large discrepancy with the seedling bank on the forest floor. We ask: 1) Does this conventional sampling strategy limit the detection of seeds of woody species? 2) Are large sample areas and sample sizes needed for higher recovery of seeds of woody species? We collected 100 samples that were 10 cm (length) × 10 cm (width) × 10 cm (depth), referred to as larger number of small-sized samples (LNSS) in a 1 ha forest plot, and placed them to germinate in a greenhouse, and collected 30 samples that were 1 m × 1 m × 10 cm, referred to as small number of large-sized samples (SNLS) and placed them (10 each) in a nearby secondary forest, shrub land and grass land. Only 15.7% of woody plant species of the forest stand were detected by the 100 LNSS, contrasting with 22.9%, 37.3% and 20.5% woody plant species being detected by SNLS in the secondary forest, shrub land and grassland, respectively. The increased number of species vs. sampled areas confirmed power-law relationships for forest stand, the LNSS and SNLS at all three recipient sites. Our results, although based on one forest, indicate that conventional LNSS did not yield a high percentage of detection for woody species, but SNLS strategy yielded a higher percentage of detection for woody species in the seed bank if samples were exposed to a better field germination environment. A 4 m2 minimum sample area derived from power equations is larger than the sampled area in most studies in the literature. Increased sample size also is needed to obtain an increased sample area if the number of samples is to remain relatively low.

Volume calculation of CT lung lesions based on Halton low-discrepancy sequences

NASA Astrophysics Data System (ADS)

Li, Shusheng; Wang, Liansheng; Li, Shuo

2017-03-01

Volume calculation from the Computed Tomography (CT) lung lesions data is a significant parameter for clinical diagnosis. The volume is widely used to assess the severity of the lung nodules and track its progression, however, the accuracy and efficiency of previous studies are not well achieved for clinical uses. It remains to be a challenging task due to its tight attachment to the lung wall, inhomogeneous background noises and large variations in sizes and shape. In this paper, we employ Halton low-discrepancy sequences to calculate the volume of the lung lesions. The proposed method directly compute the volume without the procedure of three-dimension (3D) model reconstruction and surface triangulation, which significantly improves the efficiency and reduces the complexity. The main steps of the proposed method are: (1) generate a certain number of random points in each slice using Halton low-discrepancy sequences and calculate the lesion area of each slice through the proportion; (2) obtain the volume by integrating the areas in the sagittal direction. In order to evaluate our proposed method, the experiments were conducted on the sufficient data sets with different size of lung lesions. With the uniform distribution of random points, our proposed method achieves more accurate results compared with other methods, which demonstrates the robustness and accuracy for the volume calculation of CT lung lesions. In addition, our proposed method is easy to follow and can be extensively applied to other applications, e.g., volume calculation of liver tumor, atrial wall aneurysm, etc.

Mountain erosion over decades and millennia: New insights from sediment yields and cosmogenic nuclides

NASA Astrophysics Data System (ADS)

Callahan, R. P.; Riebe, C. S.; Ferrier, K.

2017-12-01

For more than two decades, cosmogenic nuclides have been used to quantify catchment-wide erosion rates averaged over tens of thousands of years. These rates have been used as baselines for comparison with sediment yields averaged over decades, leading to insights on how human activities such as deforestation and agriculture have influenced the production and delivery of sediment to streams and oceans. Here we present new data from the southern Sierra Nevada, California, where sediment yields have been measured over the last ten years using sediment trapping and gauging methods. Cosmogenic nuclides measured in stream sediment reveal erosion rates that are between 13 and 400 (average = 94) times faster than erosion rates inferred from annual accumulations in sediment traps. We show that the discrepancy can be explained by extremely low sediment trapping efficiency, which leads to bias in the short-term rates due to incomplete capture of suspended sediment. Thus the short-term rates roughly agree with the long-term rates, despite intensive timber harvesting in the study catchments over the last century. This differs from results obtained in similar forested granitic catchments of Idaho, where long-term rates are more than ten times greater than short-term rates because large, rare events do not contribute to the short-term averages. Our analysis of a global database indicates that both the magnitude and sign of differences between short- and long-term average erosion rates are difficult to predict, even when the history of land use in known.

Power and violence: the relation between communication patterns, power discrepancies, and domestic violence.

This study hypothesized that power discrepancies in the marital relationship, where the husband is subordinate, serve as risk factors for husband-to-wife violence. The construct of marital power was assessed from 3 power domains operationalized by discrepancies in economic status, decision-making power, communication patterns, and communication skill. Three groups of married couples (N = 95) were compared: domestically violent (DV), maritally distressed/nonviolent (DNV), and maritally happy/nonviolent (HNV). DV couples were more likely than the 2 nonviolent groups to engage in husband demand/wife withdraw interactions. Within the DV group, husbands who had less power were more physically abusive toward their wives. Thus, violence may be compensatory behavior to make up for husbands' lack of power in other arenas of marriage. Difficulties in assessing marital power and future direction for the study of power and violence are discussed.

Yield: it's now an entitlement

NASA Astrophysics Data System (ADS)

George, Bill

1994-09-01

Only a few years ago, the primary method of cost reduction and productivity improvement in the semiconductor industry was increasing manufacturing yields throughout the process. Many of the remarkable reliability improvements realized over the past decade have come about as a result of actions that were originally taken primarily to improve device yields. Obviously, the practice of productivity improvement through yield enhancement is limited to the attainment of 100% yield, at which point some other mechanism must be employed. Traditionally, new products have been introduced to manufacturing at a point of relative immaturity, and semiconductor producers have relied on the traditional `learning curve' method of yield improvement to attain profitable levels of manufacturing yield. Recently, results of a survey of several fabs by a group of University of California at Berkeley researchers in the Competitive Semiconductor Manufacturing Program indicate that most factories learn at about the same rate after startup, in terms of both line yield and defectivity. If this is indeed generally true, then the most competitive factor is the one that starts with the highest yield, and it is difficult to displace a leader once his lead has been established. The two observations made above carry enormous implications for the semiconductor development or manufacturing professional. First, one must achieve very high yields in order to even play the game. Second, the achievement of competitive yields over time in the life of a factory is determined even before the factory is opened, in the planning and development phase. Third, and perhaps most uncomfortable for those of us who have relied on yield improvement as a cost driver, the winners of the nineties will find new levers to drive costs down, having already gotten the benefit of very high yield. This paper looks at the question of how the winners will achieve the critical measures of success, high initial yield and utilization

Examining the influence of actual-ideal self-discrepancies, depression, and escapism, on pathological gaming among massively multiplayer online adolescent gamers.

This study examined whether actual-ideal self-discrepancy (AISD) is related to pathological gaming through escapism as a means of reducing depression for adolescent massively multiplayer online gamers. A Discrepancy-reduction Motivation model of pathological video gaming was tested. A survey was conducted on 161 adolescent gamers from secondary schools. Two mediation effects were tested using path analysis: (a) depression would mediate the relationship between AISDs and escapism, and (b) escapism would mediate the relationship between depression and pathological gaming. Results support the hypotheses stated above. The indirect effects of both AISD and depression were significant on pathological gaming. AISD and escapism also had direct effects on pathological gaming. The present study suggests that pathological behaviors may be over-regulated coping strategies of approaching the ideal self and avoiding the actual self.

Exponentially growing, fed plateau, and unfed plateau cells in cell culture as well as small and large subcutaneous or intramuscular tumors were investigated. Large single doses of radiation followed by variable repair times as well as graded doses of radiation to generate survival curves immediately after irradiation or after full repair were investigated. All repair-promoting conditions studied in vitro (delayed subculture, exposure of cells to depleted growth medium after irradiation) increased surviving fraction after a single dose.

The most logical explanation of these data and information on radiocurability of this neoplasm is that PLD repair, which is so frequently demonstrated in vitro, may not be a major factor in the radioresponse of this tumor when left in situ.« less

Brazilian Soybean Yields and Yield Gaps Vary with Farm Size

2017-12-01

Understanding the farm size-specific characteristics of crop yields and yield gaps may help to improve yields by enabling better targeting of technical assistance and agricultural development programs. Linking remote sensing-based yield estimates with property boundaries provides a novel view of the relationship between farm size and yield structure (yield magnitude, gaps, and stability over time). A growing literature documents variations in yield gaps, but largely ignores the role of farm size as a factor shaping yield structure. Research on the inverse farm size-productivity relationship (IR) theory - that small farms are more productive than large ones all else equal - has documented that yield magnitude may vary by farm size, but has not considered other yield structure characteristics. We examined farm size - yield structure relationships for soybeans in Brazil for years 2001-2015. Using out-of-sample soybean yield predictions from a statistical model, we documented 1) gaps between the 95th percentile of attained yields and mean yields within counties and individual fields, and 2) yield stability defined as the standard deviation of time-detrended yields at given locations. We found a direct relationship between soy yields and farm size at the national level, while the strength and the sign of the relationship varied by region. Soybean yield gaps were found to be inversely related to farm size metrics, even when yields were only compared to farms of similar size. The relationship between farm size and yield stability was nonlinear, with mid-sized farms having the most stable yields. The work suggests that farm size is an important factor in understanding yield structure and that opportunities for improving soy yields in Brazil are greatest among smaller farms.

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.

Fite, Paula J.; Wynn, Porche’; Pardini, Dustin A.

2010-01-01

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.

Plant roots growing underground are critical for soil resource acquisition, anchorage and plant-environment interactions. In wheat ( Triticum aestivum ), however, the target root traits to improve yield potential still remain largely unknown. This study aimed to identify traits of seedling root system architecture (RSA) associated with yield and yield components in 226 recombinant inbred lines (RILs) derived from a cross between the bread wheat Triticum aestivum 'Forno' (small, wide root system) and spelt Triticum spelta 'Oberkulmer' (large, narrow root system). A 'pouch and wick' high-throughput phenotyping pipeline was used to determine the RSA traits of 13-day-old RIL seedlings. Two field experiments and one glasshouse experiment were carried out to investigate the yield, yield components and phenology, followed by identification of quantitative trait loci (QTLs). There was substantial variation in RSA traits between genotypes. Seminal root number and total root length were both positively associated with grains m -2 , grains per spike, above-ground biomass m -2 and grain yield. More seminal roots and longer total root length were also associated with delayed maturity and extended grain filling, likely to be a consequence of more grains being defined before anthesis. Additionally, the maximum width of the root system displayed positive relationships with spikes m -2 , grains m -2 and grain yield. Ten RILs selected for the longest total roots exhibited the same effects on yield and phenology as described above, compared with the ten lines with the shortest total roots. Genetic analysis revealed 38 QTLs for the RSA, and QTL coincidence between the root and yield traits was frequently observed, indicating tightly linked genes or pleiotropy, which concurs with the results of phenotypic correlation analysis. Based on the results from the Forno × Oberkulmer population, it is proposed that vigorous early root growth, particularly more seminal roots and longer total

The debate on the relative benefits of conventional and organic farming systems has in recent time gained significant interest. So far, global agricultural development has focused on increased productivity rather than on a holistic natural resource management for food security. Thus, developing more sustainable farming practices on a large scale is of utmost importance. However, information concerning the performance of farming systems under organic and conventional management in tropical and subtropical regions is scarce. This study presents agronomic and economic data from the conversion phase (2007-2010) of a farming systems comparison trial on a Vertisol soil in Madhya Pradesh, central India. A cotton-soybean-wheat crop rotation under biodynamic, organic and conventional (with and without Bt cotton) management was investigated. We observed a significant yield gap between organic and conventional farming systems in the 1(st) crop cycle (cycle 1: 2007-2008) for cotton (-29%) and wheat (-27%), whereas in the 2(nd) crop cycle (cycle 2: 2009-2010) cotton and wheat yields were similar in all farming systems due to lower yields in the conventional systems. In contrast, organic soybean (a nitrogen fixing leguminous plant) yields were marginally lower than conventional yields (-1% in cycle 1, -11% in cycle 2). Averaged across all crops, conventional farming systems achieved significantly higher gross margins in cycle 1 (+29%), whereas in cycle 2 gross margins in organic farming systems were significantly higher (+25%) due to lower variable production costs but similar yields. Soybean gross margin was significantly higher in the organic system (+11%) across the four harvest years compared to the conventional systems. Our results suggest that organic soybean production is a viable option for smallholder farmers under the prevailing semi-arid conditions in India. Future research needs to elucidate the long-term productivity and profitability, particularly of cotton and

Few studies have examined the frequency and survival implications of clinicopathologic stage discrepancy in oral cavity squamous cell carcinoma (SCC). Oral cavity SCC cases with full pathologic staging information were identified in the National Cancer Database (NCDB). Clinical and pathologic stages were compared. Multivariate logistic regressions were performed to identify factors associated with stage discrepancy. There were 9110 cases identified, of which 67.3% of the cases were stage concordant, 19.9% were upstaged, and 12.8% were downstaged. The N classification discordance (28.5%) was more common than T classification discordance (27.6%). In cases of T classification discordance, downstaging is more common than upstaging (15.4% vs 12.1% of cases), but in cases of N classification discordance, the reverse is true; upstaging is much more common than downstaging (20.1 vs 8.4% of cases). Clinicopathologic stage discrepancy in oral cavity SCC is a common phenomenon that is associated with a number of clinical factors and has survival implications. © 2018 Wiley Periodicals, Inc.

Production of N(+)-asterisk from N2 + hnu - Effective EUV emission yields from laboratory and dayglow data

Photodissociative ionization of N2 into the unbound N2(+) H 2Sigma-g(+) state is identified as the parentage of a number of N(+) and N-excited states that contribute to the u.v. dayglow. Yields have been obtained for the production of extreme ultraviolet emission lines of N(+) and N from a laboratory experiment using a broadband synchrotron radiation source with fluorescence spectroscopy. The yields are termed 'effective', in that they are constant percentages of the H state cross section. These are compared wih effective yields needed to reproduce N II 1085 and 916 A lines from four dayglow observations using a model of solar energy deposition and photoelectron production and loss in the earth's thermosphere. The 1085 A effective yield measured in the laboratory (18 percent) agrees with that from the dayglow data (average of 17 percent) to well within experimental uncertainties. Thus, it is concluded that photodissociative ionization of N2 is the primary source of the N II 1085 A dayglow. However, there is an order of magnitude discrepancy among the various dayglow observations of the 1085/916 intensity ratio, only one of which is consistent with the laboratory observation of 4.4. Neither contamination by other dayglow features nor atmospheric extinction can account for the disparities. Laboratory measurements of N2 and O2 absorption cross sections at these wavelengths are also reported.

Calculation of cytostatic dose is typically based on body surface area (BSA) regardless of body composition. The aim of this study was to assess the discrepancy between BSA and low fat-free mass (FFM) by investigating the prevalence of low FFM with regard to BSA in 630 cancer patients. First, BSA was calculated according to DuBois and DuBois. Patients were divided into 6 categories with respect to their BSA. Each BSA category was further divided into 3 groups according to FFM: low (<-1 SD of mean FFM), normal (-0.99 and 0.99 SD of mean FFM) or high (>1 SD of mean FFM), which was derived through bioelectric impedance analysis. FFM was reduced in 15.7% of patients, 69% had normal and 15.2% had high FFM. In patients with low FFM (i.e., more than-1 SD lower than the mean FFM within their BSA group), body mass index and fatigue were higher whereas functional status was reduced. Moreover, in the subcohort of patients receiving chemotherapy, absolute FFM [Hazard ratio (HR) = 0.970, P = 0.026] as well as the allocation to the low FFM group (HR = 1.644, P = 0.025) emerged as predictors of increased 1-yr mortality. In conclusion, there was a large discrepancy between FFM and BSA. Particularly women were affected by low FFM.

Large discrepancies observed in theoretical studies of ion-impact ionization of the atomic targets at large momentum transfer

Ghorbani, Omid; Ghanbari-Adivi, Ebrahim

2017-12-01

A full quantum mechanical version of the three-body distorted wave-eikonal initial state (3DW-EIS) theory is developed to study of the single ionization of the atomic targets by ion impact at different momentum transfers. The calculations are performed both with and without including the internuclear interaction in the transition amplitude. For 16 \\text{Mev} \\text{O}7+ \\text{-He}~(1s2 ) and 24 \\text{Mev} \\text{O}8+\\text{-Li}~(2s ) collisions, the emission of the active electron into the scattering plane is considered and the fully differential cross-sections (FDCSs) are calculated for a fixed value of the ejected electron energy and a variety of momentum transfers. For both the specified collision systems, the obtained results are compared with the experimental data and with the cross-sections obtained using the semi-classical continuum distorted wave-eikonal initial state (CDW-EIS) approach. For 16 \\text{Mev} \\text{O}7+ \\text{-He}~(1s^2) , we also compared the results with those of a four-body three-Coulomb-wave (3CW) model. In general, we find some large discrepancies between the results obtained by different theories. These discrepancies are much more significant at larger momentum transfers. Also, for some ranges of the electron emission angles the results are much more sensitive to the internuclear interaction to be either turned on or off.

Assessment of discrepancies between bottom-up and regional emission inventories in Norwegian urban areas

2017-04-01

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

Summary Background In spite the instinct social&financial impact of Leg Length Discrepancy (LLD), controversial and conflicting results still exist regarding a reliable assessment/correction method. For proper management it’s essential to discriminate between anatomical&functional Leg Length Discrepancy (FLLD). With the newly invented NPoS (New Postural Solution), under the umbrella of the collaboration of PRM Department, Tor Vergata University with Baro Postural Instruments srl, positive results were observed in both measuring& compensating the hemi-pelvic antero-medial rotation in FLLD through personalized bilateral heel raise using two NPoS components: Foot Image System (FIS) and Postural Optimizer System (POS). This led our research interest to test the validity of NPoS as a preliminary step before evaluating its implementations in postural disorders. Methods After clinical evaluation, 4 subjects with FLLD have been assessed by NPoS. Over a period of 2 months, every subject was evaluated 12 times by two different operators, 48 measurements in total, results have been verified in correlation to BTS GaitLab results. Results Intra-Operator&inter-operator variability analysis showed statistically insignificant differences, while inter-method variability between NPoS and BTS parameters expressed a linear correlation. Conclusion Results suggest a significant validity of NPoS in assessment&correction of FLLD, with high degree of reproducibility with minimal operator dependency. This can be considered a base for promising clinical implications of NPoS as a reliable cost effective postural assessment/corrective tool. Level of evidence V. PMID:29264341

Discrepancy between photodynamic injuries and pheophorbide A accumulation in digestive tissues

This report describes the discrepancy between pheophorbide A (PH-A) localization and photodynamically induced necrosis for the digestive tract. After an IV 9 mg/Kg-1 sensitization, the dye was caught by the whole digestive tract and its inherent vessels, as shown by fluorescence microscopy. The dye fluorescence disappeared within 24 h from the stomach and the jejunum. It remained high in the pancreas, the portal vein, the bile duct, the arteries and the duodenal mucosae. A light dose, 660 nm, 100 J/cm-2, 24 h after Ph-A sensitization, induced a necrosis of the duodenal mucosae. The pancreas and the hepatic pedicle were relatively unaffected by photodynamic therapy (PDT). The duodenal response to PDT results logically from its selective PH-A retention. But hepatic pedicule and pancreas immunities for PDT involve either protecting singlet oxygen scavengers or photosensitizer quenchers.

To thine own self be true? Clarifying the effects of identity discrepancies on psychological distress and emotions.

After many years of research across disciplines, it remains unclear whether people are more motivated to seek appraisals that accurately match self-views (self-verification) or are as favorable as possible (self-enhancement). Within sociology, mixed findings in identity theory have fueled the debate. A problem here is that a commonly employed statistical approach does not take into account the direction of a discrepancy between how we see ourselves and how we think others see us in terms of a given identity, yet doing so is critical for determining which self-motive is at play. We offer a test of three competing models of identity processes, including a new "mixed motivations" model where self-verification and self-enhancement operate simultaneously. We compare the models using the conventional statistical approach versus response surface analysis. The latter method allows us to determine whether identity discrepancies involving over-evaluation are as distressing as those involving under-evaluation. We use nationally representative data and compare results across four different identities and multiple outcomes. The two statistical approaches lead to the same conclusions more often than not and mostly support identity theory and its assumption that people seek self-verification. However, response surface tests reveal patterns that are mistaken as evidence of self-verification by conventional procedures, especially for the spouse identity. We also find that identity discrepancies have different effects on distress and self-conscious emotions (guilt and shame). Our findings have implications not only for research on self and identity across disciplines, but also for many other areas of research that incorporate these concepts and/or use difference scores as explanatory variables.

Estimation of rice yield affected by drought and relation between rice yield and TVDI

2016-12-01

Impact of climate change is not only seen on food production but also on food security and sustainable development of society. Adaptation to climate change is a pressing issue throughout the world to reduce the risks along with the plans and strategies for food security and sustainable development. As a key adaptation to the climate change, agricultural insurance is expected to play an important role in stabilizing agricultural production through compensating the losses caused by the climate change. As the adaptation, the Government of Indonesia has launched agricultural insurance program for damage of rice by drought, flood and pest and disease. The Government started a pilot project in 2013 and this year the pilot project has been extended to 22 provinces. Having the above as background, we conducted research on development of new damage assessment method for rice using remote sensing data which could be used for evaluation of damage ratio caused by drought in West Java, Indonesia. For assessment of the damage ratio, estimation of rice yield is a key. As the result of our study, rice yield affected by drought in dry season could be estimated at level of 1 % significance using SPOT 7 data taken in 2015, and the validation result was 0.8t/ha. Then, the decrease ratio in rice yield about each individual paddy field was calculated using data of the estimated result and the average yield of the past 10 years. In addition, TVDI (Temperature Vegetation Dryness Index) which was calculated from Landsat8 data in heading season indicated the dryness in low yield area. The result suggests that rice yield was affected by irrigation water shortage around heading season as a result of the decreased precipitation by El Nino. Through our study, it becomes clear that the utilization of remote sensing data can be promising for assessment of the damage ratio of rice production precisely, quickly and quantitatively, and also it can be incorporated into the insurance procedures.

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.

Climate Effects on Corn Yield in Missouri(.

Hu, Qi; Buyanovsky, Gregory

2003-11-01

Understanding climate effects on crop yield has been a continuous endeavor aiming at improving farming technology and management strategy, minimizing negative climate effects, and maximizing positive climate effects on yield. Many studies have examined climate effects on corn yield in different regions of the United States. However, most of those studies used yield and climate records that were shorter than 10 years and were for different years and localities. Although results of those studies showed various influences of climate on corn yield, they could be time specific and have been difficult to use for deriving a comprehensive understanding of climate effects on corn yield. In this study, climate effects on corn yield in central Missouri are examined using unique long-term (1895 1998) datasets of both corn yield and climate. Major results show that the climate effects on corn yield can only be explained by within-season variations in rainfall and temperature and cannot be distinguished by average growing-season conditions. Moreover, the growing-season distributions of rainfall and temperature for high-yield years are characterized by less rainfall and warmer temperature in the planting period, a rapid increase in rainfall, and more rainfall and warmer temperatures during germination and emergence. More rainfall and cooler-than-average temperatures are key features in the anthesis and kernel-filling periods from June through August, followed by less rainfall and warmer temperatures during the September and early October ripening time. Opposite variations in rainfall and temperature in the growing season correspond to low yield. Potential applications of these results in understanding how climate change may affect corn yield in the region also are discussed.

Discrepancies in Data Reporting for Rabies, Africa

PubMed Central

2013-01-01

Human rabies is an ancient disease but in modern times has primarily been associated with dog rabies–endemic countries of Asia and Africa. From an African perspective, the inevitable and tragic consequences of rabies require serious reflection of the factors that continue to drive its neglect. Established as a major disease only after multiple introductions during the colonial era, rabies continues to spread into new reservoirs and territories in Africa. However, analysis of reported data identified major discrepancies that are indicators of poor surveillance, reporting, and cooperation among national, international, and global authorities. Ultimately, the absence of reliable and sustained data compromises the priority given to the control of rabies. Appropriate actions and changes, in accordance to the One Health philosophy and including aspects such as synchronized, shared, and unified global rabies data reporting, will not only be necessary, but also should be feasible.

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.

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.

Self-reported sleep efficiency may not precisely reflect objective sleep patterns. We assessed whether psychosocial factors and affective responses are associated with discrepancies between subjective reports and objective measures of sleep efficiency. Participants were 199 working women aged 20 to 61 years. Standardized questionnaires were used to assess psychosocial characteristics and affect that included work stress, social support, happiness, and depressive symptoms. Objective measures of sleep were assessed on one week and one leisure night with an Actiheart monitor. Self-reported sleep efficiency was derived from the Jenkins Sleep Problems Scale. Discrepancies between self-reported and objective measures of sleep efficiency were computed by contrasting standardized measures of sleep problems with objectively measured sleep efficiency. Participants varied markedly in the discrepancies between self-reported and objective sleep measures. After adjustment for personal income, age, having children, marital status, body mass index, and negative affect, overcommitment (p = .002), low level of social support (p = .049), and poor self-rated heath (p = .02) were associated with overreporting of sleep difficulties and underestimation of sleep efficiency. Self-reported poor sleep efficiency was more prevalent among those more overcommitted at work (p = .009) and less happy (p = .02), as well as among those with lower level of social support (p = .03) and more depressive symptoms (p = .048), independently of covariates. Objective sleep efficiency was unrelated to psychosocial characteristics or affect. The extent to which self-reported evaluations of sleep efficiency reflect objective experience may be influenced by psychosocial characteristics and affect. Unless potential moderators of self-reported sleep efficiency are taken into account, associations between sleep and psychosocial factors relevant to health may be overestimated.

AIM: To investigate histological characteristics of gastric polyps in the Korean population. METHODS: We reviewed endoscopic photographs and medical records of patients with gastric polyps who underwent endoscopic mucosal resection from April 1996 through February 2003. RESULTS: A total of 85 gastric polyps from 74 patients were reviewed. Male-to-female ratio was 1:1.96. Mean age was 59.9 ± 10.8 years. Multiple polyps were observed in 10.8%. Gastric polyps occurred most frequently in the antrum (58.8%). Pathological results on resected specimens were as follows: tubular adenoma 45.9%, hyperplastic polyp 31.8%, inflammatory polyp 9.4%, hamartoma 3.5%, fundic gland polyp 2.4%, tubulovillous adenoma 2.4%, adenocarcinoma 2.4%, dysplasia 1.1%, and mucosal pseudolipomatosis 1.1%. Discrepancy rate between endoscopic biopsy and pathology of resected specimens was 27.1%. There was no relationship between the size of the polyp and concordance rate. CONCLUSION: There is considerable discrepancy in histologic findings between endoscopic forceps biopsy and resected specimens. Approaches to review of the histology of an entire polyp should be performed, especially when an adenoma is suspected. PMID:16810753

The aim of this study was to investigate and compare the marginal fit of posterior fixed dental prostheses (FDPs) made of monolithic and veneered computer-aided design/computer-assisted manufacture (CAD/CAM) zirconia ceramic with metal-ceramic posterior FDPs. Thirty standardized steel dies were prepared to receive posterior three-unit FDPs. Specimens were randomly divided into three groups (n = 10): (1) metal-ceramic (control group), (2) veneered zirconia, and (3) monolithic zirconia. All FDPs were cemented using a glass-ionomer cement. The specimens were subjected to thermal cycling (5°C to 55°C). A scanning electron microscope (SEM) with a magnification of ×500 was used for measurements. The data were statistically analyzed using one-way analysis of variance and paired t test. Both zirconia groups showed similar vertical marginal discrepancies, and no significant differences (P = .661) in marginal adaptation were observed among the groups. No differences were observed in either group in marginal discrepancies between surfaces or abutments. Monolithic zirconia posterior FDPs exhibit similar vertical marginal discrepancies to veneered zirconia posterior FDPs. No influence of localization measurements was observed.

A greenhouse experiment was conducted at the Indian Institute of Horticultural Research (IIHR), Bangalore to study the interaction effect between phosphorus (P) and zinc (Zn) on the yield and yield attributes of the medicinal plant stevia. The results show that the yield and yield attributes have been found to be significantly affected by different treatments. The total yield in terms of biomass production has been increased significantly with the application of Zn and P in different combinations and methods, being highest (23.34 g fresh biomass) in the treatment where Zn was applied as both soil (10 kg ZnSO4/ha) and foliar spray (0.2% ZnSO4). The results also envisaged that the different yield attributes viz. height, total number of branches, and number of leaves per plant have been found to be varied with treatments, being highest in the treatment where Zn was applied as both soil and foliar spray without the application of P. The results further indicated that the yield and yield attributes of stevia have been found to be decreased in the treatment where Zn was applied as both soil and foliar spray along with P suggesting an antagonistic effect between Zn and P.

Discrepancies in military middle-school adolescents' and parents' perceptions of family functioning, social support, anger frequency, and concerns.

PubMed

Crow, Janet R; Seybold, Amanda K

2013-02-01

Previous literature suggests that adolescents' and parents' perceptions of family functioning are typically quite disparate and that perceptual discrepancies increase when a family is under stress. During the years of deployments to Iraq and Afghanistan adolescents in military families have faced uniquely stressful circumstances which may exacerbate difficulties commonly experienced during adolescence. For this study 91 middle-school adolescent-parent dyads from U.S. Army families were surveyed about their perceptions of family functioning, social support, the adolescent's frequency of anger, and the adolescent's concerns. Findings indicated significant differences in parents' and adolescents' matched ratings for all variables except adolescent concerns. Adolescent-parent perceptual discrepancies were greatest for families who had never experienced deployment and during or following the first deployment. The results of this study may be useful to those supporting military families as they develop strategies to help family members understand the others' perceptions and learn to communicate and solve problems despite the differences.

A possible explanation for the population size discrepancy in tuna (genus Thunnus) estimated from mitochondrial DNA and microsatellite data.

PubMed

Qiu, Fan; Kitchen, Andrew; Beerli, Peter; Miyamoto, Michael M

2013-02-01

A recent study using both mitochondrial DNA (mtDNA) and microsatellite data reported on a population size discrepancy in the eastern tiger salamander where the effective population size (N(e)) estimate of the former exceeded that of the latter. That study suggested, among other hypotheses, that homoplasy of microsatellite alleles is responsible for the discrepancy. In this investigation, we report 10 new cases of a similar discrepancy in five species of tuna. These cases derive from our Bayesian inferences using data from Pacific Bluefin Tuna (Thunnus orientalis) and Yellowfin Tuna (Thunnus albacares), as well as from published estimates of genetic diversity for additional populations of Yellowfin Tuna and three other tuna species. Phylogenetic character analyses of inferred genealogies of Pacific Bluefin and Yellowfin Tuna reveal similar reduced levels of mtDNA and microsatellite homoplasy. Thus, the discrepancy between inferred population sizes from mtDNA and microsatellite data in tuna is most likely not an artifact of the chosen mutation models used in the microsatellite analyses, but may reflect behavioral differences between the sexes such as female-biased philopatry and male-biased dispersal. This explanation now warrants critical testing with more local populations of tuna and with other animal and plant groups that have different life histories. Copyright © 2012 Elsevier Inc.

To examine child factors and parental characteristics as predictors of discrepancies between parents' ratings of externalizing and internalizing behavior problems in a sample of preschool children with ADHD and behavior problems and in a nonclinical sample. We investigated correspondence and discrepancies between parents' ratings on the externalizing and internalizing behavior problems broadband scales of the Child Behavior Checklist version for preschool children (CBCL/1.5-5). Parents of 152 preschool children, with ADHD and behavior problems (n = 72) and nonclinical children (n = 80), aged between 28 and 72 months (M = 47.26, SD = 12.7), completed the CBCL/1.5-5. Candidate predictors of discrepancy included the child's age and sex, and parents' levels of parenting stress, depressive mood, attention-deficit and disruptive behavior. Hierarchical multiple regression analyses were conducted. Correspondence between parents, both for ratings on internalizing and externalizing behavior problems, was high (r = .63-.77). In the clinical sample, mothers rated the severity of externalizing behavior problems significantly higher than did fathers (p = < .001). Discrepancy between fathers and mothers on externalizing behavior problems was not predicted by child factors or interparental differences in psychopathology, but it was predicted by interparental differences in parenting stress (R 2  = .25, p < .001). This effect was significantly larger in the nonclinical sample (ΔR 2  = .06, p < .001). When parents disagree on the severity level of preschool children's externalizing behavior problems, the clinician should take into consideration that differences in parenting stress might be involved.

Nut crop yield records show that budbreak-based chilling requirements may not reflect yield decline chill thresholds

Warming winters due to climate change may critically affect temperate tree species. Insufficiently cold winters are thought to result in fewer viable flower buds and the subsequent development of fewer fruits or nuts, decreasing the yield of an orchard or fecundity of a species. The best existing approximation for a threshold of sufficient cold accumulation, the "chilling requirement" of a species or variety, has been quantified by manipulating or modeling the conditions that result in dormant bud breaking. However, the physiological processes that affect budbreak are not the same as those that determine yield. This study sought to test whether budbreak-based chilling thresholds can reasonably approximate the thresholds that affect yield, particularly regarding the potential impacts of climate change on temperate tree crop yields. County-wide yield records for almond ( Prunus dulcis), pistachio ( Pistacia vera), and walnut ( Juglans regia) in the Central Valley of California were compared with 50 years of weather records. Bayesian nonparametric function estimation was used to model yield potentials at varying amounts of chill accumulation. In almonds, average yields occurred when chill accumulation was close to the budbreak-based chilling requirement. However, in the other two crops, pistachios and walnuts, the best previous estimate of the budbreak-based chilling requirements was 19-32 % higher than the chilling accumulations associated with average or above average yields. This research indicates that physiological processes beyond requirements for budbreak should be considered when estimating chill accumulation thresholds of yield decline and potential impacts of climate change.

Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long-term experimental catchments across Canada and the United States over 5-year cool and warm periods. Using the theoretical framework of the Budyko curve, we calculated the effects of climate warming on the annual partitioning of precipitation (P) into evapotranspiration (ET) and water yield. Deviation (d) was defined as a catchment's change in actual ET divided by P [AET/P; evaporative index (EI)] coincident with a shift from a cool to a warm period - a positive d indicates an upward shift in EI and smaller than expected water yields, and a negative d indicates a downward shift in EI and larger than expected water yields. Elasticity was defined as the ratio of interannual variation in potential ET divided by P (PET/P; dryness index) to interannual variation in the EI - high elasticity indicates low d despite large range in drying index (i.e., resilient water yields), low elasticity indicates high d despite small range in drying index (i.e., nonresilient water yields). Although the data needed to fully evaluate ecosystems based on these metrics are limited, we were able to identify some characteristics of response among forest types. Alpine sites showed the greatest sensitivity to climate warming with any warming leading to increased water yields. Conifer forests included catchments with lowest elasticity and stable to larger water yields. Deciduous forests included catchments with intermediate elasticity and stable to smaller water yields. Mixed coniferous/deciduous forests included catchments with highest elasticity and stable water yields. Forest type appeared to influence the resilience of catchment water yields to climate warming, with conifer and deciduous catchments more susceptible to

This invitro study was conducted to compare and evaluate marginal discrepancy in two types of tooth colored self cure provisional restorative materials {DPI&UNIFAST TRAD} before and after reinforcement of glass beads. The aim of the present study was to evaluate and compare marginal discrepancy in two types of provisional restorative materials (DPI and UNI FAST TRAD) before and after reinforcement with Glass beads. Tooth shaped resin copings were fabricated on custom made brass metal die. A total of 60 resin copings were fabricated in which 30 samples were prepared with DPI and 30 samples with UNIFAST material. Each group of 30 samples were divided in to two sub groups in which 15 samples were prepared with glass bead reinforcement and 15 samples without reinforcement. The marginal discrepancy was evaluated with photomicroscope {Reichet Polyvar 2 met} by placing the resin copings on custom made brass resin coping holder. Measurements obtained were statistically analysed by unpaired t-test to know any significance between two variables. Unreinforced DPI specimens had shown lower marginal discrepancy (442.82) than reinforced specimens (585.77). Unreinforced UNIFAST specimens have shown high values of marginal discrepancy (592.83) than reinforced specimens (436.35). p-value between reinforced and unreinforced specimens of DPI (p=0.0013) and UNIFAST (p= 0.0038) has shown statistical significance. This in-vitro study revealed that unreinforced DPI specimens have shown lower marginal discrepancy than reinforced specimens and unreinforced UNIFAST specimens have shown higher values of marginal discrepancy than reinforced specimens.

Studies evaluating the marginal adaptation of available computer-aided design and computer-aided manufacturing (CAD-CAM) noble alloys for metal-ceramic prostheses are lacking. The purpose of this in vitro study was to evaluate the vertical marginal adaptation of cast, milled, and direct metal laser sintered (DMLS) noble metal-ceramic 3-unit fixed partial denture (FDP) frameworks before and after fit adjustments. Two typodont teeth were prepared for metal-ceramic FDP abutments. An acrylic resin pattern of the prepared teeth was fabricated and cast in nickel-chromium (Ni-Cr) alloy. Each specimen group (cast, milled, DMLS) was composed of 12 casts made from 12 impressions (n=12). A single design for the FDP substructure was created on a laboratory scanner and used for designing the specimens in the 3 groups. Each specimen was fitted to its corresponding cast by using up to 5 adjustment cycles, and marginal discrepancies were measured on the master Ni-Cr model before and after laboratory fit adjustments. The milled and DMLS groups had smaller marginal discrepancy measurements than those of the cast group (P<.001). Significant differences were found in the number of adjustments among the groups, with the milled group requiring the minimum number of adjustments, followed by the DMLS and cast groups (F=30.643, P<.001). Metal-ceramic noble alloy frameworks fabricated by using a CAD-CAM workflow had significantly smaller marginal discrepancies compared with those with a traditional cast workflow, with the milled group demonstrating the best marginal fit among the 3 test groups. Manual refining significantly enhanced the marginal fit of all groups. All 3 groups demonstrated marginal discrepancies within the range of clinical acceptability.

Objectification in Virtual Romantic Contexts: Perceived Discrepancies between Self and Partner Ideals Differentially affect Body Consciousness in Women and Men

Overstreet, Nicole M.; Quinn, Diane M.; Marsh, Kerry L.

2015-01-01

The current study examined whether exposure to sexually objectifying images in a potential romantic partner's virtual apartment affects discrepancies between people's perception of their own appearance (i.e., self-perceptions) and their perception of the body ideal that is considered desirable to a romantic partner (i.e., partner-ideals). Participants were 114 heterosexual undergraduate students (57 women and 57 men) from a northeastern U.S. university. The study used a 2 (Participant Gender) x 2 (Virtual Environment: Sexualized vs. Non-Sexualized) between-subjects design. We predicted that women exposed to sexually objectifying images in a virtual environment would report greater discrepancies between their self-perceptions and partner-ideals than men, which in turn would contribute to women's body consciousness. Findings support this hypothesis and show that perceived discrepancies account for the relationship between exposure to sexually objectifying images and body consciousness for women but not men. We also found gender asymmetries in objectification responses when each component of perceived discrepancies, i.e., self-perceptions versus perceptions of a romantic partner's body ideal, were examined separately. For men, exposure to muscular sexualized images was significantly associated with their self-perceptions but not their perceptions of the body size that is considered desirable to a romantic partner. For women, exposure to thin sexualized images was significantly associated with their perceptions that a romantic partner preferred a woman with a smaller body size. However, exposure to these images did not affect women's self-perceptions. Implications for gender asymmetries in objectification responses and perceived discrepancies that include a romantic partner's perceptions are discussed. PMID:26594085

Yield surface evolution for columnar ice

Zhou, Zhiwei; Ma, Wei; Zhang, Shujuan; Mu, Yanhu; Zhao, Shunpin; Li, Guoyu

A series of triaxial compression tests, which has capable of measuring the volumetric strain of the sample, were conducted on columnar ice. A new testing approach of probing the experimental yield surface was performed from a single sample in order to investigate yield and hardening behaviors of the columnar ice under complex stress states. Based on the characteristic of the volumetric strain, a new method of defined the multiaxial yield strengths of the columnar ice is proposed. The experimental yield surface remains elliptical shape in the stress space of effective stress versus mean stress. The effect of temperature, loading rate and loading path in the initial yield surface and deformation properties of the columnar ice were also studied. Subsequent yield surfaces of the columnar ice have been explored by using uniaxial and hydrostatic paths. The evolution of the subsequent yield surface exhibits significant path-dependent characteristics. The multiaxial hardening law of the columnar ice was established experimentally. A phenomenological yield criterion was presented for multiaxial yield and hardening behaviors of the columnar ice. The comparisons between the theoretical and measured results indicate that this current model is capable of giving a reasonable prediction for the multiaxial yield and post-yield properties of the columnar ice subjected to different temperature, loading rate and path conditions.

Macroclumping as solution of the discrepancy between Hα and P v mass loss diagnostics for O-type stars

Context. Recent studies of O-type stars have demonstrated that discrepant mass-loss rates are obtained when different diagnostic methods are employed. Fitting the unsaturated UV resonance lines (e.g., P v) gives drastically lower values than obtained from the Hα emission. Wind inhomogeneity (so-called "clumping") may be the main cause of this discrepancy. Aims: In a previous paper, we presented 3D Monte-Carlo calculations for the formation of scattering lines in a clumped stellar wind. In the present paper we select five O-type supergiants (from O4 to O7) and test whether the reported discrepancies can be resolved this way. Methods: In the first step, the analyses started with simulating the observed spectra with Potsdam Wolf-Rayet (PoWR) non-LTE model atmospheres. The mass-loss rates are adjusted to fit to the observed Hα emission lines best. For the unsaturated UV resonance lines (i.e., P v) we then applied our 3D Monte-Carlo code, which can account for wind clumps of any optical depths ("macroclumping"), a non-void interclump medium, and a velocity dispersion inside the clumps. The ionization stratifications and underlying photospheric spectra were adopted from the PoWR models. The properties of the wind clumps were constrained by fitting the observed resonance line profiles. Results: Our results show that with the mass-loss rates that fit Hα (and other Balmer and He ii lines), the UV resonance lines (especially the unsaturated doublet of P v) can also be reproduced with no problem when macroclumping is taken into account. There is no need to artificially reduce the mass-loss rates or to assume a subsolar phosphorus abundance or an extremely high clumping factor, unlike what was claimed by other authors. These consistent mass-loss rates are lower by a factor of 1.3 to 2.6, compared to the mass-loss rate recipe from Vink et al. Conclusions: Macroclumping resolves the previously reported discrepancy between Hα and P v mass-loss diagnostics. Based on

The agreement between Italian and Japanese endoscopists and pathologists on endoscopic and histopathological diagnoses of superficial gastric lesions is verified with the use of Paris and Vienna classifications. The correlations between Paris endoscopic types and Vienna histopathological categories is high in both the independent Italian and Japanese evaluations. However, the agreement between Italian and Japanese endoscopists is moderate due to the difficult evaluation of the height of the lesions, in particular when they are mixed. The agreement on the size of the lesions is fairly good. The probability of the same allocation to the Vienna categories of a single case is 87 per cent, disagreements remaining in dysplasia grading, between dysplasia, not only high-grade but also low-grade, and in situ carcinoma, and on cancer invasion of the lamina propria. The results indicate that use of the Paris and Vienna classifications has reduced the discrepancies between Western and Japanese endoscopists and pathologists in the diagnosis of these lesions.

Although research often relies on retrospective affect self-reports, little is known about personality's role in retrospective reports and how these converge or deviate from affect reported in the moment. This micro-longitudinal study examines personality (Neuroticism, Extraversion) and emotional salience (peak and recent affect) associations with retrospective-momentary affect report discrepancies over different time frames. Participants were 179 adults aged 20-78 (M = 48.7 years; 73.7% Caucasian/White) who each provided up to 60 concurrent affect reports over 10 days, then retrospectively reported overall intensity of each affective state after 1 day and again after 1-2 months. Multilevel models revealed that individuals retrospectively overreported or underreported various affective states, exhibiting peak associations for high arousal positive and negative affect, recency associations for low arousal positive affect, and distinct personality profiles that strengthened over time. Individuals high in both Extraversion and Neuroticism exaggerated high arousal positive and negative affect and underreported low arousal positive affect, high Extraversion/low Neuroticism individuals exaggerated high arousal positive affect and underreported low arousal positive affect, and low Extraversion/high Neuroticism individuals exaggerated high and low arousal negative affect. This study is the first to identify arousal-specific retrospective affect report discrepancies over time and suggests retrospective reports also reflect personality differences in affective self-knowledge. © 2016 Wiley Periodicals, Inc.

This study examined the effect of the threat aroused by the perception of thin-ideal images combined with beliefs about the malleability of the body on perceived/objective, ideal/objective and ought/objective body image self-discrepancies. An experimental computer program enabled women (N=82) to artificially increase or decrease the shape of their own body (previously photographed) in response to questions about their "actual", "ideal" and "ought" body self-perceptions. As predicted, results showed that women had greater body self-discrepancies when confronted with threatening thin ideals, regardless of their body mass index. The size of this trend depended on the way they were made to think of their body (malleable vs. fixed). Findings also suggested a possible relationship between body self-representations and eating behaviors or intentions. The impact of thin-ideal threats and body malleability beliefs on body perception is discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

To study discrepancies between (i) the prescribed current treatment stated by patients with congestive heart failure (CHF) compared with patients with other chronic diseases, (ii) the data in the medication list (ML) in the electronic medical record and (iii) the data in the prescription list (PL) on the prescriptions stored in the national prescription repository in Sweden, to determine current, noncurrent, duplicate and missing prescriptions. At one healthcare centre, a random sample of patients 18 years and older with a diagnosis of CHF, diabetes mellitus (DM) or osteoarthritis (OA) provided written informed consent to participate. Participants were interviewed by telephone on the prescribed current treatment. Of 161 invited patients (61 CHF, 50 DM and 50 OA), 66 patients were included. More than 80% of the patients had at least one discrepancy, a noncurrent, a duplicate or a missing prescription, in the ML and PL. The overall congruence for unique prescriptions on current treatment between the ML and the PL was only 55%. Patients with CHF had overall more discrepancies and patients with DM fewer discrepancies in the ML. Prescriptions for noncurrent treatment, duplicates and missing prescriptions are common in both the ML in the electronic medical record and the list on prescriptions stored in the Swedish National Prescription Repository. Patients with CHF had more discrepancies in the ML. The risk for medication errors in primary care due to incorrect information on prescribed treatment may be substantial.

[The value of horizontal discrepancy on the subgingival position of the tooth crown].

Marginal adaptation of the crown edge has been considered as primary and significant factor of prevention of secondary caries and periodontal disease on carryig tooth. There has been a clear dependence between hunting the periodontal tissue and the quality of edge closing of the crown. If we position subgingivaly the crown which clinically shows a good adoptiveness marginally and at the same time we position marginal crease in the ginguival sucus that should rush the accumulation of the plaque. The bacteries in the plaque would cause the inflammation of ginguive. The end of the crown edge in gingival sucus would cause chronic inflammation at ginguival tissue. The existence of transit zone that includes the crown edge, prepared tooth and dental cement became important if the crown edge has been positioned subgingivaly. If the crown edge ends in the ginguival sucus, the tooth meat is constantly being irritated that results with different degrees of inflammations. In many cases it causes ginguival dislocation. The possibility of clinical control of marginal positioning of subgingivaly positioned crown edge on demarcation line does not exist in terminal phase of cementing. The crown cement can be substratum of bacterial receptiveness and the plaque accumulation in the ginguival sucus. The procedure of cementing is an important cause of incomplete edge closing of the crown on the demarcation line. The form of demarcation line determine the form and the width of crown. They are favorising and degrading the level of marginal adaptations. The existing of horizontal discrepancy at the relation of based tooth--the crown edge is unavoidable. The question is if the amount of this discrepancy fits the assumed biological optimum.

Purpose: Intensity modulated radiation therapy (IMRT) poses a number of challenges for properly measuring commissioning data and quality assurance (QA). Understanding the limitations and use of dosimeters to measure these dose distributions is critical to safe IMRT implementation. In this work, we used Monte Carlo simulations to investigate the possible sources of discrepancy between our measurement with 2D array system and our dose calculation using our treatment planning system (TPS). Material and Methods: MCBEAM and MCSIM Monte Carlo codes were used for treatment head simulation and phantom dose calculation. Accurate modeling of a 6MV beam from Varian trilogy machine wasmore » verified by comparing simulated and measured percentage depth doses and profiles. Dose distribution inside the 2D array was calculated using Monte Carlo simulations and our TPS. Then Cross profiles for different field sizes were compared with actual measurements for zero and 90° gantry angle setup. Through the analysis and comparison, we tried to determine the differences and quantify a possible angular calibration factor. Results: Minimum discrepancies was seen in the comparison between the simulated and the measured profiles for the zero gantry angles at all studied field sizes (4×4cm{sup 2}, 10×10cm{sup 2}, 15×15cm{sup 2}, and 20×20cm{sup 2}). Discrepancies between our measurements and calculations increased dramatically for the cross beam profiles at the 90° gantry angle. This could ascribe mainly to the different attenuation caused by the layer of electronics at the base behind the ion chambers in the 2D array. The degree of attenuation will vary depending on the angle of beam incidence. Correction factors were implemented to correct the errors. Conclusion: Monte Carlo modeling of the 2D arrays and the derivation of angular dependence correction factors will allow for improved accuracy of the device for IMRT QA.« less

With an increasing and increasingly affluent population, there has been tremendous effort to examine strategies for sustainably increasing agricultural production to meet this surging global demand. Before developing new solutions from scratch, though, we believe it is important to consult our recent agricultural history to see where and how agricultural production changes have already taken place. By utilizing the newly created temporal M3 cropland datasets, we can for the first time examine gridded agricultural yields and area, both spatially and temporally. This research explores the historical drivers of agricultural production changes, from 1965-2005. The results will be presented spatially at the global-level (5-min resolution), as well as at the individual country-level. The primary research components of this study are presented below, including the general methodology utilized in each phase and preliminary results for soybean where available. The complete assessment will cover maize, wheat, rice, soybean, and sugarcane, and will include country-specific analysis for over 200 countries, states, territories and protectorates. Phase 1: The first component of our research isolates changes in agricultural production due to variation in planting decisions (harvested area) from changes in production due to intensification efforts (yield). We examine area/yield changes at the pixel-level over 5-year time-steps to determine how much each component has contributed to overall changes in production. Our results include both spatial patterns of changes in production, as well as spatial maps illustrating to what degree the production change is attributed to area and/or yield. Together, these maps illustrate where, why, and by how much agricultural production has changed over time. Phase 2: In the second phase of our research we attempt to determine the impact that area and yield changes have had on agricultural production at the country-level. We calculate a production
