Structural and spectroscopic studies of a commercial glassy carbon

NASA Astrophysics Data System (ADS)

Parker, Stewart F.; Imberti, Silvia; Callear, Samantha K.; Albers, Peter W.

2013-12-01

Glassy carbon is a form of carbon made by heating a phenolic resin to high temperature in an inert atmosphere. It has been suggested that it is composed of fullerene-like structures. The aim of the present work was to characterize the material using both structural (neutron diffraction and transmission electron microscopy) and spectroscopic (inelastic neutron scattering, Raman and X-ray photoelectron spectroscopies) methods. We find no evidence to support the suggestion of fullerene-like material being present to a significant extent, rather the model that emerges from all of the techniques is that the material is very like amorphous carbon, consisting of regions of small graphite-like basic structural units of partly stacked but mismatched structure with the edges terminated by hydrogen or hydroxyls. We do find evidence for the presence of a small quantity of water trapped in the network and suggest that this may account for batch-to-batch variation in properties that may occur.

Myositis ossificans circumscripta (MOC) is a rare benign neoplasm located in soft tissues that, most of the time, appears after a local trauma. The positive diagnosis of MOC may be challenging on CT or MRI findings. We report on an atypical case of a spontaneous nontraumatic MOC in a 54-year-old man, located in the longus supinatus muscle diagnosed with MRI and F-18 FDG PET/CT findings. Rarely described F-18 FDG PET/CT features in MOC are presented. Pattern of avid FDG focus on PET/CT, that may wrongly suggest osteosarcoma, is presented.

Imaging Findings of Ulceroglandular Tularemia.

Anand, Neil; Deochand, Osmani; Murphy, Robyn

2017-01-01

Francisella tularensis, the causative organism in Tularemia, is a relatively rare disease. There are a few radiological clues to elucidate its presence when suspicion arises. There should be strong consideration for Tularemia in the differential of any patient with its classic symptoms, diffuse cervical lymphadenopathy with evidence of necrosis, and enlarged adenoids. Ultrasound may demonstrate suppurative lymphadenopathy suggestive of infection, as in the case presented. CT often will demonstrate the extent of lymphadenopathy. On chest radiography, tularemia pneumonia is often the presenting finding, which may demonstrate bilateral or lobar infiltrates. Additionally, hilar lymphadenopathy and pleural effusions are often associated findings. Cavitary lesions may be present, which are better delineated on CT scan. We present a case of a 7-year-old male who presented with a painful right-sided palpable neck mass for 9 days, who was diagnosed with Tularemia after numerous admissions.

Ancient wolf genome reveals an early divergence of domestic dog ancestors and admixture into high-latitude breeds.

PubMed

Skoglund, Pontus; Ersmark, Erik; Palkopoulou, Eleftheria; Dalén, Love

2015-06-01

The origin of domestic dogs is poorly understood [1-15], with suggested evidence of dog-like features in fossils that predate the Last Glacial Maximum [6, 9, 10, 14, 16] conflicting with genetic estimates of a more recent divergence between dogs and worldwide wolf populations [13, 15, 17-19]. Here, we present a draft genome sequence from a 35,000-year-old wolf from the Taimyr Peninsula in northern Siberia. We find that this individual belonged to a population that diverged from the common ancestor of present-day wolves and dogs very close in time to the appearance of the domestic dog lineage. We use the directly dated ancient wolf genome to recalibrate the molecular timescale of wolves and dogs and find that the mutation rate is substantially slower than assumed by most previous studies, suggesting that the ancestors of dogs were separated from present-day wolves before the Last Glacial Maximum. We also find evidence of introgression from the archaic Taimyr wolf lineage into present-day dog breeds from northeast Siberia and Greenland, contributing between 1.4% and 27.3% of their ancestry. This demonstrates that the ancestry of present-day dogs is derived from multiple regional wolf populations. Copyright © 2015 Elsevier Ltd. All rights reserved.

Predictive validity of childhood oppositional defiant disorder and conduct disorder: implications for the DSM-V.

PubMed

Burke, Jeffrey D; Waldman, Irwin; Lahey, Benjamin B

2010-11-01

Data are presented from 3 studies of children and adolescents to evaluate the predictive validity of childhood oppositional defiant disorder (ODD) and conduct disorder (CD) as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; American Psychiatric Association, 1994) and the International Classification of Diseases, Version 10 (ICD-10; World Health Organization, 1992). The present analyses strongly support the predictive validity of these diagnoses by showing that they predict both future psychopathology and enduring functional impairment. Furthermore, the present findings generally support the hierarchical developmental hypothesis in DSM-IV that some children with ODD progress to childhood-onset CD, and some youth with CD progress to antisocial personality disorder (APD). Nonetheless, they reveal that CD does not always co-occur with ODD, particularly during adolescence. Importantly, the present findings suggest that ICD-10 diagnostic criteria for ODD, which treat CD symptoms as ODD symptoms when diagnostic criteria for CD are not met, identify more functionally impaired children than the more restrictive DSM-IV definition of ODD. Filling this "hole" in the DSM-IV criteria for ODD should be a priority for the DSM-V. In addition, the present findings suggest that although the psychopathic trait of interpersonal callousness in childhood independently predicts future APD, these findings do not confirm the hypothesis that callousness distinguishes a subset of children with CD with an elevated risk for APD.

2009-01-01

Objective To describe atypical phenotypes associated with the retinoschisis (X-linked, juvenile) 1 mutation (RS1). Methods Seven patients with multiple fine white dots at the macula and reduced visual acuity were evaluated. Six patients underwent pattern and full-field electroretinography (ERG). On-off ERG, optical coherence tomography, and fundus autofluorescence imaging were performed in some patients. Mutational screening of RS1 was prompted by the ERG findings. Results Fine white dots resembling drusenlike deposits and sometimes associated with retinal pigment epithelial abnormalities were present in the maculae. An electronegative bright-flash ERG configuration was present in all patients tested, and abnormal pattern ERG findings confirmed macular dysfunction. A parafoveal ring of high-density autofluorescence was present in 3 eyes; 1 patient showed high-density foci concordant with the white dots. Optical coherence tomography did not show foveal schisis in 3 of 4 eyes. All patients carried mutations in RS1, including 1 with a novel 206T→C mutation in exon 4. Conclusions Multiple fine white dots at the macula may be the initial fundus feature in RS1 mutation. Electrophysiologic findings suggest dysfunction after phototransduction and enable focused mutational screening. Autofluorescence imaging results suggest early retinal pigment epithelium involvement; a parafoveal ring of high-density autofluorescence has not previously been described in this disorder.

The cost of parallel consolidation into visual working memory.

PubMed

Rideaux, Reuben; Edwards, Mark

2016-01-01

A growing body of evidence indicates that information can be consolidated into visual working memory in parallel. Initially, it was suggested that color information could be consolidated in parallel while orientation was strictly limited to serial consolidation (Liu & Becker, 2013). However, we recently found evidence suggesting that both orientation and motion direction items can be consolidated in parallel, with different levels of accuracy (Rideaux, Apthorp, & Edwards, 2015). Here we examine whether there is a cost associated with parallel consolidation of orientation and direction information by comparing performance, in terms of precision and guess rate, on a target recall task where items are presented either sequentially or simultaneously. The results compellingly indicate that motion direction can be consolidated in parallel, but the evidence for orientation is less conclusive. Further, we find that there is a twofold cost associated with parallel consolidation of direction: Both the probability of failing to consolidate one (or both) item/s increases and the precision at which representations are encoded is reduced. Additionally, we find evidence indicating that the increased consolidation failure may be due to interference between items presented simultaneously, and is moderated by item similarity. These findings suggest that a biased competition model may explain differences in parallel consolidation between features.

The Swedish Hayling task, and its relation to working memory, verbal ability, and speech-recognition-in-noise.

Stenbäck, Victoria; Hällgren, Mathias; Lyxell, Björn; Larsby, Birgitta

2015-06-01

Cognitive functions and speech-recognition-in-noise were evaluated with a cognitive test battery, assessing response inhibition using the Hayling task, working memory capacity (WMC) and verbal information processing, and an auditory test of speech recognition. The cognitive tests were performed in silence whereas the speech recognition task was presented in noise. Thirty young normally-hearing individuals participated in the study. The aim of the study was to investigate one executive function, response inhibition, and whether it is related to individual working memory capacity (WMC), and how speech-recognition-in-noise relates to WMC and inhibitory control. The results showed a significant difference between initiation and response inhibition, suggesting that the Hayling task taps cognitive activity responsible for executive control. Our findings also suggest that high verbal ability was associated with better performance in the Hayling task. We also present findings suggesting that individuals who perform well on tasks involving response inhibition, and WMC, also perform well on a speech-in-noise task. Our findings indicate that capacity to resist semantic interference can be used to predict performance on speech-in-noise tasks. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Article retracted, but the message lives on.

PubMed

Greitemeyer, Tobias

2014-04-01

The retraction of an original article aims to ensure that readers are alerted to the fact that the findings are not trustworthy. However, the present research suggests that individuals still believe in the findings of an article even though they were later told that the data were fabricated and that the article was retracted. Participants in a debriefing condition and a no-debriefing condition learned about the scientific finding of an empirical article, whereas participants in a control condition did not. Afterward, participants in the debriefing condition were told that the article had been retracted because of fabricated data. Results showed that participants in the debriefing condition were less likely to believe in the findings than participants in the no-debriefing condition but were more likely to believe in the findings than participants in the control condition, suggesting that individuals do adjust their beliefs in the perceived truth of a scientific finding after debriefing-but insufficiently. Mediational analyses revealed that the availability of generated causal arguments underlies belief perseverance. These results suggest that a retraction note of an empirical article in a scientific journal is not sufficient to ensure that readers of the original article no longer believe in the article's conclusions.

A comparison of bilateral versus unilateral target and distractor presentation in the remote distractor paradigm.

PubMed

Benson, Valerie

2008-01-01

The remote distractor effect (RDE) is a robust finding of an increase in saccade onset latencies (20-40 ms) when a distractor is presented simultaneously with a target, compared to when a target is presented on its own (Walker, Deubel, Schneider, & Findlay, 1997). Distractors presented at fixation produce the largest RDE and the effect decreases as distractors are moved into the periphery. Data from two experiments that contrast with these standard findings are reported. Under bilateral target presentation, larger RDE magnitudes occurred for peripheral than for central distractors, whereas under unilateral presentation, the pattern reversed. The findings are discussed with reference to discrimination processes, attentional factors and current models of oculomotor control. It is suggested that in bilateral target presentation the competition between the distractor and the target results in the programming of a saccade to the distractor, as well as a saccade to the target. Time taken to cancel the saccade to the distractor produces the increased saccade latency for peripheral distractors in that condition.

Social skills, friendship and happiness: a cross-cultural investigation.

Demir, Melikşah; Jaafar, Jas; Bilyk, Nicholas; Ariff, Mohammad Raduan Mohd

2012-01-01

The present study investigated the associations between social skills, friendship quality, and happiness, and tested a mediational model positing that friendship quality would mediate the relationship between social skills and happiness among American and Malaysian college students. Although American students reported significantly higher levels of psychosocial well-being than Malaysian students, the study variables were positively associated with each other in both cultures. More importantly, findings supported the proposed model in both groups. Results suggest that part of the reason why social skills are associated with positive psychological well-being is because of friendship experiences. Overall, the findings of the present study reinforce, extend and cross-culturally generalize the presumed benefits of social skills in positive well-being elaborated by Segrin and Taylor (2007). The authors also provided suggestions for future research.

A role for descending auditory cortical projections in songbird vocal learning

PubMed Central

Mandelblat-Cerf, Yael; Las, Liora; Denisenko, Natalia; Fee, Michale S

2014-01-01

Many learned motor behaviors are acquired by comparing ongoing behavior with an internal representation of correct performance, rather than using an explicit external reward. For example, juvenile songbirds learn to sing by comparing their song with the memory of a tutor song. At present, the brain regions subserving song evaluation are not known. In this study, we report several findings suggesting that song evaluation involves an avian 'cortical' area previously shown to project to the dopaminergic midbrain and other downstream targets. We find that this ventral portion of the intermediate arcopallium (AIV) receives inputs from auditory cortical areas, and that lesions of AIV result in significant deficits in vocal learning. Additionally, AIV neurons exhibit fast responses to disruptive auditory feedback presented during singing, but not during nonsinging periods. Our findings suggest that auditory cortical areas may guide learning by transmitting song evaluation signals to the dopaminergic midbrain and/or other subcortical targets.

Bartter syndrome (BS) I–IV is a rare autosomal recessive disorder affecting salt reabsorption in the thick ascending limb of the loop of Henle. This report highlights clinicopathological findings and genetic studies of classic BS in a 22-year-old female patient who presented with persistent mild proteinuria for 2 years. A renal biopsy demonstrated a mild to moderate increase in the mesangial cells and matrix of most glomeruli, along with marked juxtaglomerular cell hyperplasia. These findings suggested BS associated with mild IgA nephropathy. Focal tubular atrophy, interstitial fibrosis, and lymphocytic infiltration were also observed. A genetic study of the patient and her parents revealed a mutation of the CLCNKB genes. The patient was diagnosed with BS, type III. This case represents an atypical presentation of classic BS in an adult patient. Pathologic findings of renal biopsy combined with genetic analysis and clinicolaboratory findings are important in making an accurate diagnosis. PMID:26755355

Reward Devaluation: Dot-Probe Meta-Analytic Evidence of Avoidance of Positive Information in Depressed Persons

PubMed Central

Winer, E. Samuel; Salem, Taban

2015-01-01

Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. PMID:26619211

We report three patients with hemiconvulsion-hemiplegia-epilepsy syndrome who presented acutely and were shown to have striking neuroimaging findings suggestive of diffuse cytotoxic edema confined to one hemisphere, including extensive diffusion-weighted imaging abnormalities in two cases. Two patients subsequently developed progressive and extensive atrophy of the involved hemisphere. These findings are consistent with earlier descriptions of the classic neuroradiologic features of this syndrome and are helpful in the differential diagnosis of acute infantile hemiplegia. Further, the findings support the previously proposed pathogenetic mechanism of neuronal injury caused by status epilepticus.

The pros and cons of masked priming.

PubMed

Forster, K I

1998-03-01

Masked priming paradigms offer the promise of tapping automatic, strategy-free lexical processing, as evidenced by the lack of expectancy disconfirmation effects, and proportionality effects in semantic priming experiments. But several recent findings suggest the effects may be prelexical. These findings concern nonword priming effects in lexical decision and naming, the effects of mixed-case presentation on nonword priming, and the dependence of priming on the nature of the distractors in lexical decision, suggesting possible strategy effects. The theory underlying each of these effects is discussed, and alternative explanations are developed that do not preclude a lexical basis for masked priming effects.

Incidental findings in genomic data have been studied in great detail in the recent years, especially from population-scale data sets. However, little is known about the frequency of such findings in ethnic groups, specifically the Middle East, which were not previously covered in global sequencing studies. The availability of whole exome and genome data sets for a highly consanguineous Arab population from Qatar motivated us to explore the incidental findings in this population-scale data. The sequence data of 1005 Qatari individuals were systematically analyzed for incidental genetic variants in the 59 genes suggested by the American College of Medical Genetics and Genomics. We identified four genetic variants which were pathogenic or likely pathogenic. These variants occurred in six individuals, suggesting a frequency of 0.59% in the population, much lesser than that previously reported from European and African populations. Our analysis identified a variant in RYR1 gene associated with Malignant Hyperthermia that has significantly higher frequency in the population compared to global frequencies. Evaluation of the allele frequencies of these variants suggested enrichment in sub-populations, especially in individuals of Sub-Saharan African ancestry. The present study thereby provides the information on pathogenicity and frequency, which could aid in genomic medicine. To the best of our knowledge, this is the first comprehensive analysis of incidental genetic findings in any Arab population and suggests ethnic differences in incidental findings.

2018-01-01

In this talk, I will present my latest results on the clustering and dark matter halo (DMH) mass properties of ~7000 narrowband-selected [OIII] and [OII] emitters. I will briefly describe the past work that has been done with our samples (e.g., luminosity functions, evolution of equivalent widths) as motivation of using [OIII] and [OII] emitters to study clustering/halo properties. My talk will focus on our findings regarding the line luminosity and stellar mass dependencies with DMH mass. We find strongly increasing and redshift-independent trends between line luminosity and DMH mass with evidence for a shallower slope at the bright end consistent with halo masses of ~ 1012.5-13 M⊙. Similar, but weaker, trends between stellar mass and halo mass have also been found. We investigate the inter-dependencies of these trends on halo mass and find that the correlation with line luminosity is stronger than with stellar mass. This suggest that active galaxies may be connected with their host DMHs simply based on their emission line luminosity. If time permits, I will briefly present our most recent results using our sample of ~4000 Lyα emitters, where we find similar trends to that seen with the [OIII] and [OII] samples, as well as previous Hα measurements, which suggests galaxies selected based on emission lines may be tracing the same subpopulation of star forming galaxies. I will conclude my talk with an interpretation of this connection and suggest that the shallower slope seen for the brightest emitters is evidence for a transitional halo mass as suggested in models where quenching mechanisms truncate star formation activity and reduce the fraction of star forming galaxies with increasing halo mass.

Frequency of verb use in young children who stutter.

PubMed

Wagovich, Stacy A; Bernstein Ratner, Nan

2007-01-01

Several recent studies have suggested that young children who stutter (CWS) tend to show depressed lexical performance relative to peers. Given the developmental literature as well as several studies of verb processing in individuals who stutter, verbs may pose a particular challenge for this group. The purpose of the present study was to examine verb use in CWS. In theory, if young CWS differ in their production of verbs, this finding would partially explain the findings of studies that probed conversational vocabulary skills more generally. Fifteen CWS and 15 children who do not stutter (CWNS) participated in a play-based conversational sample with a parent. Samples were analyzed for the total number of verbs, the number of different verbs, and the proportion of general all-purpose (GAP) verbs within the samples. CWS produced significantly fewer different verbs and total verbs than the CWNS. However, previously reported near-significant differences in utterance length between groups would appear to temper the robustness of this finding. The groups did not differ in the proportion of GAP verbs used, suggesting that the CWS did not over-rely on GAP verbs in conversational language production but rather used these verbs to the same extent as their peers. As a result of this activity, the participant will be able to: (1) relate the purpose and rationale for examining verb use in children who stutter (CWS); (2) summarize the procedures used to assess verb use and GAP verb use in the present study; (3) explain the findings of the present study; (4) relate findings to the extant literature on lexical diversity in CWS.

Is Accessing of Words Affected by Affective Valence Only? A Discrete Emotion View on the Emotional Congruency Effect

PubMed Central

Chen, Xuqian; Liu, Bo; Lin, Shouwen

2016-01-01

This paper advances the discussion on which emotion information affects word accessing. Emotion information, which is formed as a result of repeated experiences, is primary and necessary in learning and representing word meanings. Previous findings suggested that valence (i.e., positive or negative) denoted by words can be automatically activated and plays a role in many significant cognitive processes. However, there has been a lack of discussion about whether discrete emotion information (i.e., happiness, anger, sadness, and fear) is also involved in these processes. According to the hierarchy model, emotions are considered organized within an abstract-to-concrete hierarchy, in which emotion prototypes are organized following affective valence. By controlling different congruencies of emotion relations (i.e., matches or mismatches between valences and prototypes of emotion), the present study showed both an evaluative congruency effect (Experiment 1) and a discrete emotional congruency effect (Experiment 2). These findings indicate that not only affective valences but also discrete emotions can be activated under the present priming lexical decision task. However, the present findings also suggest that discrete emotions might be activated at the later priming stage as compared to valences. The present work provides evidence that information about discrete emotion could be involved in word processing. This might be a result of subjects’ embodied experiences. PMID:27379000

The purpose of this study was to determine the yield of acutely abnormal findings on head CT scans in patients presenting to the emergency department with dizziness, near-syncope, or syncope and to determine the clinical factors that potentially predicted acutely abnormal head CT findings and hospital admission. We retrospectively reviewed the electronic medical records of all patients presenting to an HMO emergency department between July 1, 2012, and December 31, 2012, who underwent head CT for a primary complaint of dizziness, syncope, or near-syncope. The primary outcomes were head CT scans with acutely abnormal findings and hospital admission. Binary logistic regression was used to assess the association between clinical variables and acute head CT findings and between clinical variables and hospital admission. Of the 253 patients who presented with dizziness, 7.1% had head CT scans with acutely abnormal findings, and 18.6% were admitted. Of the 236 patients who presented with syncope or near-syncope, 6.4% had head CT scans with acutely abnormal findings, and 39.8% were admitted. The following three clinical factors were found to be significantly correlated with acutely abnormal head CT findings: a focal neurologic deficit (p = 0.003), age greater than 60 years (p = 0.011), and acute head trauma (p = 0.026). Our results suggest that most patients presenting with syncope or dizziness to the emergency department may not benefit from head CT unless they are older, have a focal neurologic deficit, or have a history of recent head trauma.

Movement and Other Neurodegenerative Syndromes in Patients with Systemic Rheumatic Diseases

2015-01-01

Abstract Patients with rheumatic diseases can present with movement and other neurodegenerative disorders. It may be underappreciated that movement and other neurodegenerative disorders can encompass a wide variety of disease entities. Such disorders are strikingly heterogeneous and lead to a wider spectrum of clinical injury than seen in Parkinson's disease. Therefore, we sought to stringently phenotype movement and other neurodegenerative disorders presenting in a case series of rheumatic disease patients. We integrated our findings with a review of the literature to understand mechanisms which may account for such a ubiquitous pattern of clinical injury. Seven rheumatic disease patients (5 Sjögren's syndrome patients, 2 undifferentiated connective tissue disease patients) were referred and could be misdiagnosed as having Parkinson's disease. However, all of these patients were ultimately diagnosed as having other movement or neurodegenerative disorders. Findings inconsistent with and more expansive than Parkinson's disease included cerebellar degeneration, dystonia with an alien-limb phenomenon, and nonfluent aphasias. A notable finding was that individual patients could be affected by cooccurring movement and other neurodegenerative disorders, each of which could be exceptionally rare (ie, prevalence of ∼1:1000), and therefore with the collective probability that such disorders were merely coincidental and causally unrelated being as low as ∼1-per-billion. Whereas our review of the literature revealed that ubiquitous patterns of clinical injury were frequently associated with magnetic resonance imaging (MRI) findings suggestive of a widespread vasculopathy, our patients did not have such neuroimaging findings. Instead, our patients could have syndromes which phenotypically resembled paraneoplastic and other inflammatory disorders which are known to be associated with antineuronal antibodies. We similarly identified immune-mediated and inflammatory markers of injury in a psoriatic arthritis patient who developed an amyotrophic lateral sclerosis (ALS)-plus syndrome after tumor necrosis factor (TNF)-inhibitor therapy. We have described a diverse spectrum of movement and other neurodegenerative disorders in our rheumatic disease patients. The widespread pattern of clinical injury, the propensity of our patients to present with co-occurring movement disorders, and the lack of MRI neuroimaging findings suggestive of a vasculopathy collectively suggest unique patterns of immune-mediated injury.

Applying a social identity paradigm to examine the relationship between men's self-esteem and their attitudes toward men and women.

PubMed

Maltby, John; Day, Liza

2003-02-01

The authors used a psychometrically robust measure of attitudes toward men in applying a social identity framework to obtain a better understanding of the previous finding of a significant positive relationship, among men, between self-esteem and attitudes toward men. Two studies of that issue are reported. Northern Irish university students (N = 106 men) participated in the 1st study, and 56 English university students participated in a replication. In both studies, participants completed measures of attitudes toward men and women before and after an experimental intervention that was designed to produce a threat to self-esteem regarding their identity as men. The findings suggested that, following such a threat, men with a high positive regard toward men will have enhanced self-regard toward men and will tend to view women more negatively. The present findings also suggested that the application of social identity theory and the method used in the present research in investigating that theory are very relevant to the understanding of the relationship between men's self-esteem and their attitudes toward men and women.

Impossible is nothing: 5:3 and 4:3 multi-frequency bimanual coordination.

Kovacs, Attila J; Buchanan, John J; Shea, Charles H

2010-03-01

The present findings demonstrate that when participants are provided a Lissajous display with cursor indicating the position of the limbs and a template illustrating the desired movement pattern they can rapidly (10 min) and effectively (continuous relative phase errors and variability ~10 degrees ) tune in a difficult 5:3 bimanual coordination pattern and without additional practice re-tune their responding to an equally difficult 4:3 coordination pattern. The findings indicate the extreme difficulty associated with producing complex polyrhythms in previous experiments has been due to split attention when Lissajous feedback has been provided and inability of the participant to detect and correct coordination errors when only provided vision of the limbs. Effective transfer to the 4:3 polyrhythm without previous practice suggests that the perception-action system's capabilities are extensive. The present findings when viewed in the context of recent experiments using similar protocols suggest that much, but not all, of the difficulty associated with producing a variety of bimanual coordination tasks should be viewed in terms of perceptual constraints imposed by the testing environment.

Reward devaluation: Dot-probe meta-analytic evidence of avoidance of positive information in depressed persons.

PubMed

Winer, E Samuel; Salem, Taban

2016-01-01

Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. (c) 2015 APA, all rights reserved).

Use of Lumbar Punctures in the Management of Ocular Syphilis.

Ocular syphilis has become rare in the developed world, but is a common presentation to ophthalmology departments in South Africa. We investigated the proportion of patients diagnosed with ocular syphilis who went on to receive lumbar punctures, and determined the fraction of these who had cerebrospinal fluid findings suggestive of neurosyphilis. We aimed to determine whether the use of lumbar punctures in ocular syphilis patients was beneficial in picking up cases of neurosyphilis. Retrospective study of case notes of patients admitted to two district hospitals in Durban, South Africa, with ocular syphilis over a 20-month period. A total of 31 of 68 ocular syphilis patients underwent lumbar puncture, and of these, eight (25.8%) had findings suggestive of neurosyphilis. Lumbar puncture in ocular syphilis patients should continue to be a routine part of the investigation of these patients; a large proportion of ocular syphilis patients show cerebrospinal fluid findings suggestive of neurosyphilis, are at risk of the complications of neurosyphilis, and should be managed accordingly.

Paying substance abusers in research studies: where does the money go?

Festinger, David S; Dugosh, Karen Leggett

2012-01-01

Research involving substance-abusing participants is often hindered by low rates of recruitment and retention. Research suggests that monetary payment or remuneration can be an effective strategy to overcome these obstacles. This article provides a brief overview of these issues and provides data reflecting how substance-abusing participants in several of our studies used their baseline and follow-up payments. We also present research findings related to how the mode of payment (i.e., cash, check, gift card) may affect how payments are used. Overall, our findings suggest that participants use their research payments in a responsible and safe manner. Limitations and recommendations for future research are discussed.

Influence of multiple categories on the prediction of unknown properties

PubMed Central

Verde, Michael F.; Murphy, Gregory L.; Ross, Brian H.

2006-01-01

Knowing an item's category helps us predict its unknown properties. Previous studies suggest that when asked to evaluate the probability of an unknown property, people tend to consider only an item's most likely category, ignoring alternative categories. In the present study, property prediction took the form of either a probability rating or a speeded, binary-choice judgment. Consistent with past findings, subjects ignored alternative categories in their probability ratings. However, their binary-choice judgments were influenced by alternative categories. This novel finding suggests that the way category knowledge is used in prediction depends critically on the form of the prediction. PMID:16156183

This paper reports progress in developing a computer model of language acquisition in the form of (1) a generative grammar that is (2) algorithmically learnable from realistic corpus data, (3) viable in its large-scale quantitative performance and (4) psychologically real. First, we describe new algorithmic methods for unsupervised learning of generative grammars from raw CHILDES data and give an account of the generative performance of the acquired grammars. Next, we summarize findings from recent longitudinal and experimental work that suggests how certain statistically prominent structural properties of child-directed speech may facilitate language acquisition. We then present a series of new analyses of CHILDES data indicating that the desired properties are indeed present in realistic child-directed speech corpora. Finally, we suggest how our computational results, behavioral findings, and corpus-based insights can be integrated into a next-generation model aimed at meeting the four requirements of our modeling framework.

The effect of social dominance orientation on perceptions of corporal punishment.

PubMed

Hess, Chelsie A; Gray, Jennifer M; Nunez, Narina L

2012-09-01

Previous research has suggested the use of corporal punishment is widely endorsed in our society (Straus, 2000; Straus & Stewart, 1999). Furthermore, perceptions of what constitutes corporal punishment vary. The present study examined social dominance orientation (SDO) and age of child as potential factors that may influence perceptions of what is viewed as corporal punishment versus physical abuse. The sample consisted of 206 undergraduate students enrolled at a Rocky Mountain University. A series of regressions were used to examine the relationships between SDO and six forms of punishment. Findings suggest, higher levels of SDO are significantly related to more ratings of physical punishment versus physical abuse. The primary findings of the present study showed SDO was significantly related to how an individual perceives corporal punishment. These results have important implications by serving as a stepping-stone into further understanding what factors may have an influence on perceptions of corporal punishment.

Distal 11q deletion, previously known as Jacobsen syndrome, is caused by segmental aneusomy for the distal end of the long arm of chromosome 11. Typical clinical features include facial dysmorphism, mild-to-moderate psychomotor retardation, trigonocephaly, cardiac defects, and thrombocytopenia. There is a significant variability in the range of clinical features. We report herein a five-year-old girl with severe ophthalmological findings, facial dysmorphism, and psychomotor retardation with normal platelet function, in whom a de novo 11q23 deletion was detected, suggesting that distal 11q monosomy should be kept in mind in patients presenting with dysmorphic facial features and psychomotor retardation even in the absence of hematological findings.

Radiological findings of gastric adenomyoma in a neonate presenting with gastric outlet obstruction.

2013-03-01

Gastric adenomyoma is a rare tumour-like lesion composed of glandular components and smooth muscle bundles. We report a case of gastric adenomyoma in a 1-week-old neonate who presented with gastric outlet obstruction. To the best of our knowledge, this is the youngest child reported with gastric adenomyoma and a unique case demonstrating radiological findings of gastric adenomyoma in a young infant. At US, the lesion was seen as an asymmetrical mass-like wall-thickening of the pylorus. Upper gastrointestinal series showed findings similar to those seen in a case of hypertrophic pyloric stenosis. We suggest that gastric adenomyoma should be included in the causes of gastric outlet obstruction in neonates even though it is rare in young children.

Optimization of a Small Scale Linear Reluctance Accelerator

NASA Astrophysics Data System (ADS)

Barrera, Thor; Beard, Robby

2011-11-01

Reluctance accelerators are extremely promising future methods of transportation. Several problems still plague these devices, most prominently low efficiency. Variables to overcoming efficiency problems are many and difficult to correlate how they affect our accelerator. The study examined several differing variables that present potential challenges in optimizing the efficiency of reluctance accelerators. These include coil and projectile design, power supplies, switching, and the elusive gradient inductance problem. Extensive research in these areas has been performed from computational and theoretical to experimental. Findings show that these parameters share significant similarity to transformer design elements, thus general findings show current optimized parameters the research suggests as a baseline for further research and design. Demonstration of these current findings will be offered at the time of presentation.

Out of Control!? How Loss of Self-Control Influences Prosocial Behavior: The Role of Power and Moral Values

PubMed Central

Joosten, Anne; van Dijke, Marius; Van Hiel, Alain; De Cremer, David

2015-01-01

Lack of self-control has been suggested to facilitate norm-transgressing behaviors because of the operation of automatic selfish impulses. Previous research, however, has shown that people having a high moral identity may not show such selfish impulses when their self-control resources are depleted. In the present research, we extended this effect to prosocial behavior. Moreover, we investigated the role of power in the interaction between moral identity and self-control depletion. More specifically, we expected that power facilitates the externalization of internal states, which implies that for people who feel powerful, rather than powerless, depletion decreases prosocial behavior especially for those low in moral identity. A laboratory experiment and a multisource field study supported our predictions. The present finding that the interaction between self-control depletion and moral identity is contingent upon people’s level of power suggests that power may enable people to refrain from helping behavior. Moreover, the findings suggest that if organizations want to improve prosocial behaviors, it may be effective to situationally induce moral values in their employees. PMID:26024380

We are presenting a rare case of toxoplasma lymphadenopathy with hyper viscosity syndrome due to polyclonal gammopathy. A 30 year old female presented with generalized lymphadenopathy. Lymph node biopsy findings suggestive of toxoplasmosis were confirmed on serology. Bone marrow aspiration showed 50 % plasma cells. On serum electrophoresis broad, diffuse band noted, indicative of polyclonal gammopathy. M band was absent. The patient was immunocompetent and presented with hyper viscosity syndrome masking the symptoms of underlying toxoplasmosis.

The purpose of the present paper is to provide an integrated overview of the research methodology and key findings from a decade of research on family meals as part of Project EAT (Eating Among Teens), a large, population-based study of adolescents. Focus groups conducted with 141 middle-school and high-school adolescents suggested the importance of family meals in influencing adolescents' food choices. These findings led to the inclusion of questions on family meals in the Project EAT-I survey, completed by 4746 middle-school and high-school students, and in the Project EAT-II longitudinal survey, completed by 2516 of the original participants five years later. A subset of 902 parents also participated in telephone interviews as part of Project EAT-I. Findings indicate that many adolescents and parents view family meals in a positive light, but there is great diversity in the context and frequency of family meal patterns in the homes of adolescents. Findings further suggest that family meals may have benefits in terms of dietary intake, disordered eating behaviours, substance use and psychosocial health. Findings from Project EAT, in conjunction with other research studies on family meals, suggest the importance of working with families to increase the frequency and improve the quality of family meals. Further research is needed in order to elucidate the pathways that underpin the relationships between family meals and health outcomes. Suggestions for a future research agenda based on what was learned from Project EAT are provided.

A 2-year-old boy with Martin-Bell syndrome was referred for molecular testing and found to have a large deletion of FMRI. His mother was found to have two FMR-1 alleles in the normal range for CGG repeats. DNA probes located both proximal and distal to FRAXA were used to delineate the approximation location of the deletion endpoints. Proximal to the fragile site, DXS312 (pX135) was absent but DXS98 (4D8) was present. Distal to the fragile site, DXS296 (VK21) was absent but DXS304 (U6.2) was present. Our patient does not appear to have clinical findings other than those typically associated with fragilemore » X syndrome suggesting that the deletion does not remove other contiguous genes, e.g., IDS. The deletion in this patient is larger than the patient reported by Gedeon et al., in whom approximately 2.5 megabases were estimated to be deleted. Using the physical map of Schlessinger et al., the physical extent of the deletion can be estimated to be at least 3 megabases. This patient may be useful in physical mapping of the chromosomal region near FMR-1. Continued long-term evaluation of this patient may uncover clinical findings suggestive that the deletion removes other genes near to FMR-1 or, alternatively, no findings atypical of the fragile X syndrome suggesting that no other genes lie in the deletion interval.« less

Training-Dependent Associative Learning Induced Neocortical Structural Plasticity: A Trace Eyeblink Conditioning Analysis

Chau, Lily S.; Prakapenka, Alesia V.; Zendeli, Liridon; Davis, Ashley S.; Galvez, Roberto

2014-01-01

Studies utilizing general learning and memory tasks have suggested the importance of neocortical structural plasticity for memory consolidation. However, these learning tasks typically result in learning of multiple different tasks over several days of training, making it difficult to determine the synaptic time course mediating each learning event. The current study used trace-eyeblink conditioning to determine the time course for neocortical spine modification during learning. With eyeblink conditioning, subjects are presented with a neutral, conditioned stimulus (CS) paired with a salient, unconditioned stimulus (US) to elicit an unconditioned response (UR). With multiple CS-US pairings, subjects learn to associate the CS with the US and exhibit a conditioned response (CR) when presented with the CS. Trace conditioning is when there is a stimulus free interval between the CS and the US. Utilizing trace-eyeblink conditioning with whisker stimulation as the CS (whisker-trace-eyeblink: WTEB), previous findings have shown that primary somatosensory (barrel) cortex is required for both acquisition and retention of the trace-association. Additionally, prior findings demonstrated that WTEB acquisition results in an expansion of the cytochrome oxidase whisker representation and synaptic modification in layer IV of barrel cortex. To further explore these findings and determine the time course for neocortical learning-induced spine modification, the present study utilized WTEB conditioning to examine Golgi-Cox stained neurons in layer IV of barrel cortex. Findings from this study demonstrated a training-dependent spine proliferation in layer IV of barrel cortex during trace associative learning. Furthermore, findings from this study showing that filopodia-like spines exhibited a similar pattern to the overall spine density further suggests that reorganization of synaptic contacts set the foundation for learning-induced neocortical modifications through the different neocortical layers.

Comparing the MMPI-2 scale scores of parents involved in parental competency and child custody assessments.

PubMed

Resendes, John; Lecci, Len

2012-12-01

MMPI-2 scores from a parent competency sample (N = 136 parents) are compared with a previously published data set of MMPI-2 scores for child custody litigants (N = 508 parents; Bathurst et al., 1997). Independent samples t tests yielded significant and in some cases substantial differences on the standard MMPI-2 clinical scales (especially Scales 4, 8, 2, and 0), with the competency sample obtaining higher clinical scores as well as higher scores on F, FB, VRIN, TRIN, and L, but lower scores on K, relative to the custody sample. Despite the higher scores in the competency sample, MMPI-2 mean scores did not exceed the clinical cutoff (T > 65). Moreover, the present competency sample essentially replicates the MMPI-2 scores of a previously published competency sample, suggesting that the present findings are representative of that population. The present findings suggest that separate reference groups be used when conducting child custody vs. parental competency evaluations, as these appear to be distinct populations despite there being similarities in the testing circumstances.

The Role of Task-Related Learned Representations in Explaining Asymmetries in Task Switching

PubMed Central

Barutchu, Ayla; Becker, Stefanie I.; Carter, Olivia; Hester, Robert; Levy, Neil L.

2013-01-01

Task switch costs often show an asymmetry, with switch costs being larger when switching from a difficult task to an easier task. This asymmetry has been explained by difficult tasks being represented more strongly and consequently requiring more inhibition prior to switching to the easier task. The present study shows that switch cost asymmetries observed in arithmetic tasks (addition vs. subtraction) do not depend on task difficulty: Switch costs of similar magnitudes were obtained when participants were presented with unsolvable pseudo-equations that did not differ in task difficulty. Further experiments showed that neither task switch costs nor switch cost asymmetries were due to perceptual factors (e.g., perceptual priming effects). These findings suggest that asymmetrical switch costs can be brought about by the association of some tasks with greater difficulty than others. Moreover, the finding that asymmetrical switch costs were observed (1) in the absence of a task switch proper and (2) without differences in task difficulty, suggests that present theories of task switch costs and switch cost asymmetries are in important ways incomplete and need to be modified.

Encoding instructions and stimulus presentation in local environmental context-dependent memory studies.

Markopoulos, G; Rutherford, A; Cairns, C; Green, J

2010-08-01

Murnane and Phelps (1993) recommend word pair presentations in local environmental context (EC) studies to prevent associations being formed between successively presented items and their ECs and a consequent reduction in the EC effect. Two experiments were conducted to assess the veracity of this assumption. In Experiment 1, participants memorised single words or word pairs, or categorised them as natural or man made. Their free recall protocols were examined to assess any associations established between successively presented items. Fewest associations were observed when the item-specific encoding task (i.e., natural or man made categorisation of word referents) was applied to single words. These findings were examined further in Experiment 2, where the influence of encoding instructions and stimulus presentation on local EC dependent recognition memory was examined. Consistent with recognition dual-process signal detection model predictions and findings (e.g., Macken, 2002; Parks & Yonelinas, 2008), recollection sensitivity, but not familiarity sensitivity, was found to be local EC dependent. However, local EC dependent recognition was observed only after item-specific encoding instructions, irrespective of stimulus presentation. These findings and the existing literature suggest that the use of single word presentations and item-specific encoding enhances local EC dependent recognition.

Prostate carcinoma mimicking a sphenoid wing meningioma

2015-01-01

Introduction We report here on a rare case of a large, lateral sphenoid wing tumor with radiographic and intraoperative findings highly suggestive of meningioma, yet pathology was in fact consistent with metastatic prostate adenocarcinoma. Presentation of case An 81 year-old male presented with expressive dysphasia, right-sided weakness and headaches. Imaging revealed a heterogeneously-enhancing lesion based on the left lateral sphenoid wing. The presumed diagnosis was strongly in favor of meningioma, and the patient underwent complete resection of the dural-based lesion. Final pathology confirmed the unexpected finding of a metastatic prostate adenocarcinoma. Although he tolerated surgery well, the patient was subsequently referred for palliative therapy given findings of widespread systemic disease. Discussion Intracranial metastases may involve the dura, at times presenting with rare radiographic features highly suggestive for meningioma, as in our case here. This makes differentiation, at least based on imaging, a challenge. Elderly patients presenting with neurological deficits secondary to a newly-diagnosed, dural-based lesion should thus be considered for metastasis, prompting additional imaging studies (including body CT, MRI or PET) to rule out a primary lesion elsewhere. In some cases, this may affect the overall decision to proceed with surgical resection, or alternatively, to proceed directly to palliative therapy (the latter decision made in the context of widespread metastatic disease). Conclusion We conclude that dural-based metastatic lesions may mimic meningiomas, warranting thorough pre-operative work-up to exclude the possibility of metastasis. In certain cases, identification of widespread disease might preclude surgery and favor palliation, instead. PMID:26318129

Brief report: Representational momentum for dynamic facial expressions in pervasive developmental disorder.

Uono, Shota; Sato, Wataru; Toichi, Motomi

2010-03-01

Individuals with pervasive developmental disorder (PDD) have difficulty with social communication via emotional facial expressions, but behavioral studies involving static images have reported inconsistent findings about emotion recognition. We investigated whether dynamic presentation of facial expression would enhance subjective perception of expressed emotion in 13 individuals with PDD and 13 typically developing controls. We presented dynamic and static emotional (fearful and happy) expressions. Participants were asked to match a changeable emotional face display with the last presented image. The results showed that both groups perceived the last image of dynamic facial expression to be more emotionally exaggerated than the static facial expression. This finding suggests that individuals with PDD have an intact perceptual mechanism for processing dynamic information in another individual's face.

We present two siblings with identical clinical findings that seem to represent a previously unreported familial syndrome. Major findings involve three systems: pulmonary arterial hypertension, cardiac abnormalities including secundum-type atrial septal defect, and the hematopoietic system with intermittent neutropenia, lymphopenia, monocytosis, and anemia. The siblings also shared several minor abnormalities: pectus carinatum, long fingers, proximally placed thumb, broad nasal bridge, and high-arched palate. The male proband also had bilateral inguinal hernias and undescended testes. The same findings in two siblings suggest a genetic cause--either an autosomal recessive disorder or germline mosaicism in one parent for a dominant mutation. Investigations revealed a bone morphogenetic protein receptor 2 polymorphism in intron 4 in only one sibling, which was also present in unaffected maternal relatives.

Paying Substance Abusers in Research Studies: Where Does the Money Go?

2013-01-01

Research involving substance abusing participants is often hindered by low rates of recruitment and retention. Research suggests that monetary payment or remuneration can be an effective strategy to overcome these obstacles. This paper provides a brief overview of these issues and provides data reflecting how substance abusing participants in several of our studies used their baseline and follow-up payments. We also present research findings related to how the mode of payment (i.e.., cash, check, gift card) may affect how payments are used. Overall, our findings suggest that participants use their research payments in a responsible and safe manner. Limitations and recommendations for future research are discussed. PMID:22185328

New daily persistent headache: clinical and serological characteristics in a retrospective study.

2004-10-01

We present a retrospective clinical study of 18 cases of new daily persistent headache (NDPH), a rare chronic headache, included in the fourth chapter of the II IHS classification; the pathophysiology of NDPH is unknown but a link with viral infections (especially Epstein-Barr virus (EBV)) has been suggested. Comparing our series with the other two published until now, we did not find any particular difference, as regards to clinical aspects. However, our laboratory tests show a recent herpes simplex virus infection in 42% and cytomegalovirus in 11% of cases; moreover we could not find any EBV infection. Our data suggest that viruses other than EBV can play a role in NDPH.

We present analysis results of high-energy observations of the extreme mass-ratio black-widow millisecond pulsar binary PSR J1311-3430. Our studies in the UV, X-ray, and gamma-ray bands confirm the orbital modulation in the gamma-ray band as suggested previously. In addition, we find that the modulation is stronger in the high-energy band. In the lower-energy UV and X-ray bands, we detect flares which were observed previously and attributed to magnetic activities. We find that the optical flares are associated with the X-ray flares, suggesting common origin. We explore possible connections of the variabilities with the intrabinary shock (IBS) and magnetic activity on the low mass companion.

Parasystole due to re-entry as the possible mechanism of ventricular parasystole with second-degree entrance block.

Kinoshita, Shinji; Katoh, Takakazu; Yoshida, Hiroshi

2010-05-01

In 1974, Kinoshita reported a case of 'irregular parasystole' due to type I second-degree entrance block. Since then, many cases of such 'irregular' parasystole have been reported by us. To explain the mechanism of 'irregular' parasystole, two theories have been suggested, namely, 'electrotonic modulation' by Jalife and Moe, and 'type I second-degree entrance block' by us. On the contrary, in 1960, Kinoshita et al. reported a case of concealed bigeminy for the first time. The electrocardiographic findings in concealed bigeminy have suggested that there are dual re-entrant pathways with markedly long effective refractory periods in the re-entrant pathway. We have suggested that parasystole may be caused by re-entry in such re-entrant pathways. In this article, attempts are made to explain the mechanism of all the electrocardiographic findings in our cases of parasystole by 'parasystole due to re-entry'. Using 24 studies on parasystole and 21 studies on concealed extrasystoles that we have reported over 50 years, as well as three exemplary cases in this article, attempts are made to explain all electrocardiographic findings in parasystole by 'parasystole due to re-entry'. The electrocardiographic findings in our previous clinical cases of parasystole and concealed extrasystoles, as well as exemplary cases and diagrams in the present article, strongly suggest 'parasystole due to re-entry' as the mechanism of ventricular parasystole with second-degree entrance block.

Changes in adolescents' conflict responses associated with consecutive presentation of hypothetical conflict situations.

The advantages of using hypothetical situations are one reason they have been widely used to examine adolescents' responses to conflict situations. One frequently used research protocol involves presenting several conflict scenarios to participants during a single session. However, in real-life situations multiple conflicts rarely occur within short periods of time, and the nature of this presentation may be associated with changes in adolescents' reports of conflict behaviors. Trend analyses of emotional, conflict goal, and conflict tactic responses from grade 8, 10, 12, and college students to consecutively presented conflict situations showed that responses were associated with presentation of the hypothetical situations. Findings revealed an increase in reports of assertive conflict behaviors and a decrease in reports of constructive conflict behaviors with successive situation presentation. Results from the current study suggest that researchers must consider trends in responses when examining findings from successive situation presentation methodologies because adolescent reports of conflict behavior may change as situation presentation proceeds.

Endemic PCs and high incidence of malignant mesothelioma from household use of asbestos have been reported in Metsovo in northwestern Greece ('Metsovo lung'). In the present study, we present similar findings in six more areas of Greece. Like Metsovo, all these areas are located within ophiolite belts. Like Metsovo, material similar to 'Metsovo whitewash' has been used for various domestic uses. Asbestos fibers (chrysotile, antigorite and tremolite) were found in three of the six areas. Also, in two, MPM has been diagnosed. These findings suggest that 'Metsovo lung' occurs in several areas of Greece and has similar etiology and epidemiology.

Dysphagia is commonly attributed to disorders arising from dysfunction of the oesophageal mucosa or oesophageal motility. Mediastinal structures causing compression of the oesophagus remain a rare presenting cause of dysphagia. We report a case of a woman presenting with dysphagia to solid foods and associated symptoms of weight loss. Traditional evaluation for dysphagia was unrevealing until cross-sectional imaging suggested a mediastinal obstructive process. The finding of a mediastinal granuloma, distinct from mediastinal fibrosis, as the aetiology of dysphagia is a rare finding, with specific treatment implications. The patient was treated with itraconazole antifungal therapy with an improvement in her symptoms. 2016 BMJ Publishing Group Ltd.

Spontaneous Trait Inferences on Social Media.

PubMed

Levordashka, Ana; Utz, Sonja

2017-01-01

The present research investigates whether spontaneous trait inferences occur under conditions characteristic of social media and networking sites: nonextreme, ostensibly self-generated content, simultaneous presentation of multiple cues, and self-paced browsing. We used an established measure of trait inferences (false recognition paradigm) and a direct assessment of impressions. Without being asked to do so, participants spontaneously formed impressions of people whose status updates they saw. Our results suggest that trait inferences occurred from nonextreme self-generated content, which is commonly found in social media updates (Experiment 1) and when nine status updates from different people were presented in parallel (Experiment 2). Although inferences did occur during free browsing, the results suggest that participants did not necessarily associate the traits with the corresponding status update authors (Experiment 3). Overall, the findings suggest that spontaneous trait inferences occur on social media. We discuss implications for online communication and research on spontaneous trait inferences.

Clarification of the memory artefact in the assessment of suggestibility.

PubMed

Willner, P

2008-04-01

The Gudjonsson Suggestibility Scale (GSS) assesses suggestibility by asking respondents to recall a short story, followed by exposure to leading questions and pressure to change their responses. Suggestibility, as assessed by the GSS, appears to be elevated in people with intellectual disabilities (ID). This has been shown to reflect to some extent the fact that people with ID have poor recall of the story; however, there are discrepancies in this relationship. The aim of the present study was to investigate whether a closer match between memory and suggestibility would be found using a measure of recognition memory rather than free recall. Three modifications to the procedure were presented to users of a learning disabilities day service. In all three experiments, a measure of forced-choice recognition memory was built into the suggestibility test. In experiments 1 and 2, the GSS was presented using either divided presentation (splitting the story into two halves, with memory and suggestibility tests after each half) or multiple presentation (the story was presented three times before presentation of the memory and suggestibility tests). Participants were tested twice, once with the standard version of the test and once with one of the modified versions. In experiment 3, an alternative suggestibility scale (ASS3) was created, based on real events in a learning disabilities day service. The ASS3 was presented to one group of participants who had been present at the events, and a second group who attended a different day service, to whom the events were unfamiliar. As observed previously, suggestibility was not closely related to free recall performance: recall was increased equally by all three manipulations, but they produced, respectively, no effect, a modest effect and a large effect on suggestibility. However, the effects on suggestibility were closely related to performance on the forced-choice recognition memory task: divided presentation of the GSS2 had no effect on either of these measures; multiple presentation of the GSS2 produced a modest increase in recognition memory and a modest decrease in suggestibility; and replacing the GSS with the ASS3 produced a large increase in recognition memory and a large decrease in suggestibility. The results support earlier findings that the GSS is likely to overestimate how suggestible a person will be in relation to a personally significant event. This reflects poor recognition memory for the material being tested, rather than increased suggestibility per se. People with ID may in fact be relatively non-suggestible for well-remembered events, which would include personally significant events, particularly those witnessed recently.

Attitudes toward hiring applicants with mental illness and criminal justice involvement: the impact of education and experience.

Batastini, Ashley B; Bolanos, Angelea D; Morgan, Robert D

2014-01-01

Individuals with mental health diagnoses, as well as those involved in the criminal justice system, experience a number of barriers in the recovery and reintegration progress, including access to stable, prosocial employment opportunities. Employment for these populations is important for establishing financial security, reducing unstructured leisure time, increasing self-worth, and improving interpersonal skills. However, research has demonstrated that individuals with psychiatric and/or criminal backgrounds may experience stigmatizing attitudes from employers that impede their ability to find adequate work. This study aimed to evaluate stigmatizing beliefs toward hypothetical applicants who indicated a mental health history, a criminal history, or both, as well as the effectiveness of psychoeducation in reducing stigma. Participants consisted of 465 individuals recruited from a large university who completed a series of online questions about a given applicant. Results of this study varied somewhat across measures of employability, but were largely consistent with extant research suggesting that mental illness and criminal justice involvement serve as deterrents when making hiring decisions. Overall, psychoeducation appeared to reduce stigma for hiring decisions when the applicant presented with a criminal history. Unfortunately, similar findings were not revealed when applicants presented with a psychiatric or a psychiatric and criminal history. Implications and limitations of these findings are presented, along with suggestions for future research. Copyright © 2014 Elsevier Ltd. All rights reserved.

On the relationship between emotional state and abnormal unfairness sensitivity in alcohol dependence.

PubMed

Brevers, Damien; Noël, Xavier; Hanak, Catherine; Verbanck, Paul; Kornreich, Charles

2015-01-01

Recent empirical findings suggest that alcohol dependence is characterized by heightened sensitivity to unfairness during social transactions. The present study went a step further and aimed to ascertain whether this abnormal level of sensitivity to unfairness is underlined by an increased emotional reactivity. Twenty-six recently abstinent alcohol-dependent (AD) individuals and 32 controls performed an ultimatum game (UG), in which participants had to respond to take-it-or-leave-it offers, ranging from fair to unfair and made by a fictive proposer. Emotional state was recorded during UG offers presentation and was indexed by the amplitude of skin conductance response (SCR). Results showed that AD decided to reject unfair offers more frequently than their controls, confirming previous data. The proportion of rejected unfair UG offers was correlated with SCR, in the AD but not in the control group. This finding suggests that deciding to accept or reject unfair UG offers is influenced by arousal-affective activity in AD, but not in controls. Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent. An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions. Future studies are needed in order to examine whether-emotional and behavioral-reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD.

Practice increases procedural errors after task interruption.

PubMed

Altmann, Erik M; Hambrick, David Z

2017-05-01

Positive effects of practice are ubiquitous in human performance, but a finding from memory research suggests that negative effects are possible also. The finding is that memory for items on a list depends on the time interval between item presentations. This finding predicts a negative effect of practice on procedural performance under conditions of task interruption. As steps of a procedure are performed more quickly, memory for past performance should become less accurate, increasing the rate of skipped or repeated steps after an interruption. We found this effect, with practice generally improving speed and accuracy, but impairing accuracy after interruptions. The results show that positive effects of practice can interact with architectural constraints on episodic memory to have negative effects on performance. In practical terms, the results suggest that practice can be a risk factor for procedural errors in task environments with a high incidence of task interruption.

Using Art For Health Promotion: Evaluating an In-School Program Through Student Perspectives.

PubMed

McKay, Fiona H; McKenzie, Hayley

2017-09-01

The value of incorporating arts-based approaches into health promotion programs has long been recognized as useful in affecting change. Such approaches have been used in many schools across Australia and have been found to promote general well-being and mental health. Despite these positive findings, few programs have used or evaluated an integrated arts-based approach to achieve health and well-being goals. This article presents the findings of an evaluation of an integrated arts-based program focused on creativity and improving well-being in students. The findings of this evaluation suggest that students who took part in the program were more interested in art and music at the end of the program and had gained an overall increase in awareness and mindfulness and a positivity toward leisure activities. This evaluation provides some evidence to suggest that this type of program is a promising way to promote well-being in schools.

“Don’t Think Paralysis Takes Away Your Womanhood”: Sexual Intimacy After Spinal Cord Injury

PubMed Central

Dillaway, Heather; Lysack, Cathy L.

2015-01-01

Sexuality and intimacy are important components of health and well-being. Issues surrounding sexuality and intimacy are equally important for men and women living with physical disabilities, including spinal cord injury (SCI). Yet, women’s sexuality after SCI remains largely unexamined. This article presents the findings from an in-depth qualitative investigation of the sexual and reproductive health experiences of 20 women with SCI in or around Detroit, MI. Findings echo existing literature documenting the sexual consequences of life after SCI and suggest new areas of inquiry important for better addressing sexual concerns across the lifespan. Specifically, findings suggest a need to consider the variable effects of SCI on sexual intimacy in relation to a person’s developmental trajectory, the appropriate timing of sexual education, the need to expand conceptualizations of sexual intimacy, and the ways SCI may affect sexuality in later life.

Evidence for Deficits in the Temporal Attention Span of Poor Readers

PubMed Central

Visser, Troy A. W.

2014-01-01

Background While poor reading is often associated with phonological deficits, many studies suggest that visual processing might also be impaired. In particular, recent research has indicated that poor readers show impaired spatial visual attention spans in partial and whole report tasks. Given the similarities between competition-based accounts for reduced visual attention span and similar explanations for impairments in sequential object processing, the present work examined whether poor readers show deficits in their “temporal attention span” – that is, their ability to rapidly and accurately process sequences of consecutive target items. Methodology/Principal Findings Poor and normal readers monitored a sequential stream of visual items for two (TT condition) or three (TTT condition) consecutive target digits. Target identification was examined using both unconditional and conditional measures of accuracy in order to gauge the overall likelihood of identifying a target and the likelihood of identifying a target given successful identification of previous items. Compared to normal readers, poor readers showed small but consistent deficits in identification across targets whether unconditional or conditional accuracy was used. Additionally, in the TTT condition, final-target conditional accuracy was poorer than unconditional accuracy, particularly for poor readers, suggesting a substantial cost arising from processing the previous two targets that was not present in normal readers. Conclusions/Significance Mirroring the differences found between poor and normal readers in spatial visual attention span, the present findings suggest two principal differences between the temporal attention spans of poor and normal readers. First, the consistent pattern of reduced performance across targets suggests increased competition amongst items within the same span for poor readers. Second, the steeper decline in final target performance amongst poor readers in the TTT condition suggests a reduction in the extent of their temporal attention span. PMID:24651313

Consumer Health Information and the Demand for Physician Visits.

PubMed

Schmid, Christian

2015-12-01

The present study empirically investigates the effect of consumer health information on the demand for physician visits. Using a direct information measure based on questions from the Swiss Health Survey, we estimate a Poisson hurdle model for office visits. We find that information has a negative effect on health care utilization, contradicting previous findings in the literature. We consider differences in the used information measures to be the most likely explanation for the different findings. However, our results suggest that increasing consumer health information has the potential to reduce health care expenditures. Copyright © 2014 John Wiley & Sons, Ltd.

2017-04-01

The present study compares depressive symptoms in adolescents from three countries: Mumbai, India; Seattle, United States; and Melbourne, Australia measured using the Short Moods and Feelings Questionnaire (SMFQ). The study cross nationally compares SMFQ depressive symptom responses by age and gender. Data from a cross-nationally matched survey were used to compare factorial and measurement characteristics from samples of students from Grade 7 and 9 in Mumbai, India (n=3268) with the equivalent cohorts in the Washington State, USA (n=1907) and Victoria, Australia (n=1900). Exploratory Structural Equation Modelling (ESEM) was used to cross-nationally examine factor structure and measurement invariance. A number of reports suggesting that SMFQ is uni-dimensional were not supported in findings from any country. A model with two factors was a better fit and suggested a first factor clustering symptoms that were affective and physiologically based symptoms and a second factor of self-critical, cognitive symptoms. The two-factor model showed convincing cross national configural invariance and acceptable measurement invariance. The present findings revealed that adolescents in Mumbai, India, reported substantially higher depressive symptoms in both factors, but particularly for the self-critical dimension, as compared to their peers in Australia and the USA and that males in Mumbai report high levels of depressive symptoms than females in Mumbai. the cross sectional study collected data for adolescents in Melbourne and Seattle in 2002 and the data for adolescents in Mumbai was obtained in 2010-2011 CONCLUSIONS: These findings suggest that previous findings in developed nations of higher depressive symptoms amongst females compared to males may have an important cultural component and cannot be generalised as a universal feature of adolescent development.

Emotions in cognitive conflicts are not aversive but are task specific.

PubMed

Schacht, Annekathrin; Dimigen, Olaf; Sommer, Werner

2010-09-01

It has been suggested that cognitive conflicts require effortful processing and, therefore, are aversive (Botvinick, 2007). In the present study, we compared conflicts emerging from the inhibition of a predominant response tendency in a go/no-go task with those between incompatible response activations in a Simon task in a within-subjects design, using the same type of stimuli. Whereas no-go trials elicited reduced skin conductance and pupillometric responses, but prolonged corrugator muscle activity, as compared with go trials, incompatible and compatible Simon trials were indistinguishable with respect to these parameters. Furthermore, the conflict-sensitive N2 components of the event-related brain potential were similar in amplitude, but showed significantly different scalp distributions, indicating dissociable neural generator systems. The present findings suggest the involvement of different emotional and cognitive processes in both types of cognitive conflicts-none being aversive, however. In addition, the N2 findings call into question claims of common monitoring systems for all kinds of cognitive conflicts.

Freestanding lipid bilayers were challenged with 15 nm Au nanospheres either coated by a citrate layer or passivated by a protein corona. The effect of Au nanospheres on the bilayer morphology, permeability and fluidity presents strong differences or similarities, depending on the observation length scale, from the colloidal to the molecular domains. These findings suggest that the interaction between nanoparticles and lipid membranes should be conveniently treated as a multiscale phenomenon.Freestanding lipid bilayers were challenged with 15 nm Au nanospheres either coated by a citrate layer or passivated by a protein corona.

[The effect of self-reflection on depression mediated by hardiness].

PubMed

Nakajima, Miho; Hattori, Yosuke; Tanno, Yoshihiko

2015-10-01

Previous studies have shown that two types of private self-consciousness result in opposing effects on depression; one of which is self-rumination, which leads to maladaptive effect, and the other is self-reflection, which leads to an adaptive effect. Although a number of studies have examined the mechanism of the maladaptive effect of self-rumination, only a few studies have examined the mechanism of the adaptive effect of self-reflection. The present study examined the process of how self-reflection affected depression adaptively, Based on the previous findings, we proposed a hypothetical model assuming that hardiness acts as a mediator of self-reflection. To test the validity of the model, structural equation modeling analysis was performed with the cross-sectional data of 155 undergraduate students. The results. suggest that the hypothetical model is valid. According to the present results and previous findings, it is suggested that self-reflection is associated with low levels of depression and mediated by "rich commitment", one component of hardiness.

Cross-Field Comparison of Ethics Education: Golden Rules and Particulars.

Mulhearn, Tyler J; Watts, Logan L; Torrence, Brett S; Todd, E Michelle; Turner, Megan R; Connelly, Shane; Mumford, Michael D

2017-01-01

Research misconduct negatively impacts the scientific community and society in general. Providing training in the responsible conduct of research (RCR) to researchers is one viable approach to minimizing research misconduct. Although recent evidence suggests ethics training can indeed be effective, little empirical work has examined the similarities and differences across fields. In the present study, we analyzed 62 empirical studies in engineering, biomedical science, social science, and mixed fields. The findings suggest certain instructional principles, or "golden rules," apply generally to all fields. These golden rules include maintaining a field-specific or field-general approach and emphasizing processes in training. The findings also suggest that content areas contributing to instructional effectiveness vary as a function of field. Generally, it appears that all fields may benefit from taking a multi-pronged approach to ethics education wherein the salient field issues are covered. Implications for RCR education are discussed.

Inoculating against eyewitness suggestibility via interpolated verbatim vs. gist testing.

PubMed

Pansky, Ainat; Tenenboim, Einat

2011-01-01

In real-life situations, eyewitnesses often have control over the level of generality in which they choose to report event information. In the present study, we adopted an early-intervention approach to investigate to what extent eyewitness memory may be inoculated against suggestibility, following two different levels of interpolated reporting: verbatim and gist. After viewing a target event, participants responded to interpolated questions that required reporting of target details at either the verbatim or the gist level. After 48 hr, both groups of participants were misled about half of the target details and were finally tested for verbatim memory of all the details. The findings were consistent with our predictions: Whereas verbatim testing was successful in completely inoculating against suggestibility, gist testing did not reduce it whatsoever. These findings are particularly interesting in light of the comparable testing effects found for these two modes of interpolated testing.

Prostitution advertisements suggest association of transvestism and masochism.

PubMed

Chivers, M; Blanchard, R

1996-01-01

Previous research and clinical observation have suggested that the sexual interest of many transvestites include involvement in sadomasochistic sexual acts. Through data gathered via prostitution advertisements in print media, we tested the hypothesis that prostitutes welcoming cross-dressing client would be primarily those describing themselves as dominant. The specialty of the prostitute was recorded by coding the advertisements for the presence or absence of the features of dominance, submissiveness, acceptance of cross-dressing clients, and whether the prostitute was a biological male presenting as a woman or quasi-woman. The findings showed that 20% of prostitutes describing themselves as dominant welcomed cross-dressing clients, whereas none of the other subgroups of prostitutes mentioned cross-dressing clients in their advertisements. These findings reinforce other lines of indirect evidence suggesting that, in heterosexual men, the presence of masochism increases the likelihood of transvestism, and vice versa.

Knowing who's boss: implicit perceptions of status from the nonverbal expression of pride.

PubMed

Shariff, Azim F; Tracy, Jessica L

2009-10-01

Evolutionary theory suggests that the universal recognition of nonverbal expressions of emotions functions to enhance fitness. Specifically, emotion expressions may send survival-relevant messages to other social group members, who have the capacity to automatically interpret these signals. In the present research, we used 3 different implicit association methodologies to test whether the nonverbal expression of pride sends a functional, automatically perceived signal about a social group member's increased social status. Results suggest that the pride expression strongly signals high status, and this association cannot be accounted for by positive valence or artifacts of the expression such as expanded size due to outstretched arms. These findings suggest that the pride expression may function to uniquely communicate the high status of those who show it. Discussion focuses on the implications of these findings for social functions of emotion expressions and the automatic communication of status.

Cognitive dysfunction in schizophrenia: convergence of gamma-aminobutyric acid and glutamate alterations.

PubMed

Lewis, David A; Moghaddam, Bita

2006-10-01

Impairments in certain cognitive functions mediated by the dorsolateral prefrontal cortex, such as working memory, are core features of schizophrenia. Convergent findings suggest that these disturbances are associated with alterations in markers of inhibitory gamma-aminobutyric acid and excitatory glutamate neurotransmission in the dorsolateral prefrontal cortex. Specifically, reduced gamma-aminobutyric acid synthesis is present in the subpopulation of gamma-aminobutyric acid neurons that express the calcium-binding protein parvalbumin. Despite presynaptic and postsynaptic compensatory responses, the resulting impaired inhibitory regulation of pyramidal neurons contributes to a reduction in the synchronized neuronal activity that is required for working memory function. Several lines of evidence suggest that these changes may be either secondary to or exacerbated by impaired signaling via the N-methyl-d-aspartate class of glutamate receptors. These findings suggest specific targets for therapeutic interventions to improve cognitive function in individuals with schizophrenia.

Numerous eosinophilic globules (skeinoid fibers) in a duodenal stromal tumor: an exceptional case showing smooth muscle differentiation.

PubMed

Matsukuma, S; Doi, M; Suzuki, M; Ikegawa, K; Sato, K; Kuwabara, N

1997-11-01

A unique case of duodenal stromal tumor in a 51-year-old man is reported. The tumor histologically showed spindle cell proliferation and numerous eosinophilic globules. Most globules were composed of tangled 45 nm thick fibrils, which were ultrastructurally identical to 'skeinoid fibers'. The presence of glycogen granules in the tumor cells and the immunoreactivity for alpha-smooth muscle actin suggested smooth muscle differentiation. Focal ultrastructural findings also supported the smooth muscle nature of this tumor. There were no immunohistochemical and ultrastructural features indicating neural differentiation. In previous studies, the presence of such 'skeinoid fibers' was suggested to be a histological marker for neural differentiation in gastrointestinal stromal tumor. However, the findings in the present case suggest that numerous 'skeinoid fibers' can be identified in duodenal stromal tumor with smooth muscle differentiation, although this condition may be rare.

Reexamining the Relationship between Verbal Knowledge Background and Keyword Training for Vocabulary Acquisition

PubMed

Hogben; Lawson

1997-07-01

The literature on keyword training presents a confusing picture of the usefulness of the keyword method for foreign language vocabulary learning by students with strong verbal knowledge backgrounds. This paper reviews research which notes the existence of conflicting sets of findings concerning the verbal background-keyword training relationship and presents the results of analyses which argue against the assertion made by McDaniel and Pressley (1984) that keyword training will have minimal effect on students with high verbal ability. Findings from regression analyses of data from two studies did not show that the relationship between keyword training and immediate recall performance was moderated by verbal knowledge background. The disparate sets of findings related to the keyword training-verbal knowledge relationship and themes emerging from other research suggest that this relationship requires further examination.

False-positive psychology: undisclosed flexibility in data collection and analysis allows presenting anything as significant.

PubMed

Simmons, Joseph P; Nelson, Leif D; Simonsohn, Uri

2011-11-01

In this article, we accomplish two things. First, we show that despite empirical psychologists' nominal endorsement of a low rate of false-positive findings (≤ .05), flexibility in data collection, analysis, and reporting dramatically increases actual false-positive rates. In many cases, a researcher is more likely to falsely find evidence that an effect exists than to correctly find evidence that it does not. We present computer simulations and a pair of actual experiments that demonstrate how unacceptably easy it is to accumulate (and report) statistically significant evidence for a false hypothesis. Second, we suggest a simple, low-cost, and straightforwardly effective disclosure-based solution to this problem. The solution involves six concrete requirements for authors and four guidelines for reviewers, all of which impose a minimal burden on the publication process.

A Meta-Synthesis of Qualitative Findings About Dance/Movement Therapy for Individuals With Trauma.

PubMed

Levine, Brooklyn; Land, Helen M

2016-02-01

The therapeutic potential of using dance/movement therapy is being increasingly recognized. Preliminary interdisciplinary research findings suggest engaging the body in trauma treatment might reduce the length of treatment by addressing the connections among thoughts, feelings, neurobiology, and somatic responses in the survivor. Unfortunately, empirical research investigating its effectiveness as a psychotherapeutic intervention has been limited due to the lack of a clear manual for mental health care practitioners. The present study aims to synthesize findings from the existing qualitative literature in a qualitative meta-synthesis. Our findings will contribute to the development of a body-oriented intervention for mental health care practitioners to use for trauma. © The Author(s) 2015.

A 37-year-old man with a known history of neurofibromatosis 1 (NF1) presented within 2 days of diarrhoeal illness followed by encephalopathy, facial twitching, hypoglycaemia, hypotension, tachycardia and low-grade fever. Examination showed multiple café-au-lait spots and neurofibromas over the trunk, arms and legs and receptive aphasia with right homonymous hemianopia, which resolved. Workup for cardiac, inflammatory and infectious aetiologies was unrevealing. A brain MRI showed gyral swelling with increased T2 fluid-attenuated inversion recovery signal and diffusion restriction in the left cerebral cortex. Neuroendocrine findings suggested panhypopituitarism with centrally derived adrenal insufficiency. Supportive treatment, hormone supplementation, antibiotics, antivirals and levetiracetam yielded clinical improvement. A follow-up brain MRI showed focal left parieto-occipital atrophy with findings of cortical laminar necrosis. In conclusion, we describe a case of NF1-associated panhypopituitarism presenting as hypoglycaemic seizures and stroke-like findings, hitherto unreported manifestations of NF1. Prompt recognition and treatment of these associated conditions can prevent devastating complications. 2015 BMJ Publishing Group Ltd.

Hyperthyroid dementia: clinicoradiological findings and response to treatment.

PubMed

Fukui, T; Hasegawa, Y; Takenaka, H

2001-02-15

Dementia associated with hyperthyroidism is less well documented than is hypothyroid dementia. Therapeutic response of hyperthyroid dementia and associated cerebral circulatory and/or metabolic abnormalities has not been elucidated. We described a patient with hyperthyroid dementia and clinicoradiological response to treatment. Single photon emission computed tomographic (SPECT) study was repeated and analyzed semiquantitatively. A 67-year-old man experienced progressive impairments of attention, memory, constructive skills and behavior as well as hand tremor and weight loss of two-year duration. Laboratory findings were compatible with Graves' disease. The initial SPECT showed diffuse tracer uptake defect with an accentuation in the bilateral temporoparietal regions. Clinical and SPECT findings both suggested concurrent "possible" Alzheimer's disease. However, initial treatment with a beta-blocker improved behavior and attention-related cognitive functions as well as tracer uptake in the frontal lobes. Subsequent treatment with additional methimazole then improved memory and constructive abilities when a euthyroid state was established. Uptake defect in the temporoparietal regions also responded gradually to the medication. We suggest that the present patient represent hyperthyroid dementia, which responds favorably to treatment with regard to clinical symptoms and SPECT findings. We also suggest that thyroid function be measured in patients with "possible" Alzheimer's disease because treatable hyperthyroid dementia may not be identified.

Dentinogenesis imperfecta associated with short stature, hearing loss and mental retardation: a new syndrome with autosomal recessive inheritance?

2005-08-01

The follow-up history and oral findings in two brothers from consanguineous parents suggest that the association of dentinogenesis imperfecta (DI), delayed tooth eruption, mild mental retardation, proportionate short stature, sensorineural hearing loss and dysmorphic facies may represent a new syndrome with autosomal recessive inheritance. Histological examination of the dentin matrix of a permanent molar from one of the siblings reveals morphological similarities with defective dentinogenesis as presenting in patients affected with Osteogenesis Imperfecta (OI), a condition caused by deficiency of type I collagen. A number of radiographic and histological characteristics, however, are inconsistent with classical features of DI. These findings suggest that DI may imply greater genetical heterogeneity than currently assumed.

Social media interruption affects the acquisition of visually, not aurally, acquired information during a pathophysiology lecture.

2018-06-01

Poor academic performance from extensive social media usage appears to be due to students' inability to multitask between distractions and academic work. However, the degree to which visually distracted students can acquire lecture information presented aurally is unknown. This study examined the ability of students visually distracted by social media to acquire information presented during a voice-over PowerPoint lecture, and to compare performance on examination questions derived from information presented aurally vs. that presented visually. Students ( n = 20) listened to a 42-min cardiovascular pathophysiology lecture containing embedded cartoons while taking notes. The experimental group ( n = 10) was visually, but not aurally, distracted by social media during times when cartoon information was presented, ~40% of total lecture time. Overall performance among distracted students on a follow-up, open-note quiz was 30% poorer than that for controls ( P < 0.001). When the modality of presentation (visual vs. aural) was compared, performance decreased on examination questions from information presented visually. However, performance on questions from information presented aurally was similar to that of controls. Our findings suggest the ability to acquire information during lecture may vary, depending on the degree of competition between the modalities of the distraction and the lecture presentation. Within the context of current literature, our findings also suggest that timing of the distraction relative to delivery of material examined affects performance more than total distraction time. Therefore, when delivering lectures, instructors should incorporate organizational cues and active learning strategies that assist students in maintaining focus and acquiring relevant information.

The clinical characteristics of esophageal eosinophilia (EE), which is essential for diagnosis of eosinophilic esophagitis (EoE), have not been fully clarified in a Japanese population. The aim of this study was to analyze the reliability of symptoms and endoscopic findings for diagnosing EE in Japanese individuals. We prospectively enrolled subjects who complained of esophageal symptoms suggesting EoE and/or those with endoscopic findings of suspected EoE at the outpatient clinics of 12 hospitals. Diagnostic utility was compared between the EE and non-EE groups using logistic regression analysis. A total of 349 patients, including 319 with symptoms and 30 with no symptoms but endoscopic findings suggesting EoE were enrolled. Of those with symptoms, 8 (2.5%) had EE, and 3 were finally diagnosed with EoE. Of those without symptoms but endoscopic findings, 4 had EE. Among 8 symptomatic patients, 7 had abnormal endoscopic findings suspicious of EoE. Although dysphagia was a major symptom in EE, none of the presenting symptoms was useful for diagnosis of EE. Among the endoscopic findings, linear furrow was the most reliable (OR = 41.583). EE is uncommon among patients with esophageal symptoms in Japanese individuals. The most useful endoscopic finding for diagnosis of EE was linear furrow, whereas subjective symptoms were not supportive. © 2014 S. Karger AG, Basel.

Damage evaluation and repair methods for prestressed concrete bridge members

1980-11-01

The types of accidental damage occurring and the severity and frequency of their occurrence are summarized. Practices and equipment used for assessing damage and making repairs are presented and evaluated. Guidelines for inspection, assessing damage, and selection of repair methods are given. Methods of repair includes adding external prestress, a metal sleeve splice, and splicing broken strands or rods. The findings of this study suggest that in some instances better repair techniques should be used. The findings of this study also indicate that proper selection of repair methods may reduce the number of damaged girders presently being replaced. Plausible methods of repair requiring additional research are identified and techniques for testing are outlined.

The aim of the present study was to investigate the factorial validity of the Brunel Mood Scale for use with Malaysian athletes. Athletes (N = 1485 athletes) competing at the Malaysian Games completed the Brunel of Mood Scale (BRUMS). Confirmatory Factor Analysis (CFA) results indicated a Confirmatory Fit Index (CFI) of .90 and Root Mean Squared Error of Approximation (RMSEA) was 0.05. The CFI was below the 0.95 criterion for acceptability and the RMSEA value was within the limits for acceptability suggested by Hu and Bentler, 1999. We suggest that results provide some support for validity of the BRUMS for use with Malaysian athletes. Given the large sample size used in the present study, descriptive statistics could be used as normative data for Malaysian athletes. Key pointsFindings from the present study lend support to the validity of the BRUMS for use with Malaysian athletes.Given the size of the sample used in the present study, we suggest descriptive data be used as the normative data for researchers using the scale with Malaysian athletes.It is suggested that future research investigate the effects of cultural differences on emotional states experienced by athletes before, during and post-competition.

Cytologic findings of toxoplasmic lymphadenitis (TL) have been only sporadically reported. Intramammary lymph node is an extremely rare site for TL. A 47-year-old, healthy, female presented with a breast tumor, which was aspirated. The cytomorphologic features were interpreted as suggestive of TL. Histopathology of the excisional biopsy specimen and subsequent serologic examination confirmed the diagnosis. We obtained several characteristic findings in aspiration of TL. Of these, epithelioid cell clusters and monocytoid cells were the most diagnostic.

Imaging in the evaluation of renovascular disease

PubMed Central

Roebuck, Derek J.; McLaren, Clare A.; Marks, Stephen D.

2009-01-01

Renovascular disease (RVD) is an important cause of hypertension in children, as it often is amenable to potentially curative treatment. Imaging aimed at finding RVD therefore needs to have high sensitivity so as not to miss important findings. Digital subtraction angiography is the gold standard investigation. Doppler ultrasonography, computed tomography (CT) angiography and magnetic resonance (MR) angiography can all be helpful, but none has, at present, high enough sensitivity to rule out RVD in a child with a suggestion of that diagnosis.

A rare but possibly underreported urological emergency is penile fracture which results from tear in the tunica albuginea of the penis. The proposed etiology is forceful manipulation of an erect penis or secondary to blunt trauma. We would like to report a case of young patient presenting with large penile shaft hematoma and deformity. The patient did not provide obvious history of trauma or sexual intercourse. The ultrasound of penis was performed which suggested the diagnosis of penile fracture and ultrasound findings were correlated with peroperative findings.

A case of temporal lobe epilepsy with improvement of clinical symptoms and single photon emission computed tomography findings after treatment with clonazepam.

PubMed

Ide, M; Mizukami, K; Suzuki, T; Shiraishi, H

2000-10-01

A 26-year-old female presented psychomotor seizures, deja vu and amnestic syndrome after meningitis at the age of 14 years. Repeated electroencephalograms (EEG) demonstrated occasional spikes localized in the right temporal region in addition to a considerable amount of theta waves mainly in the right fronto-temporal region. Single photon emission computed tomography (SPECT) showed a marked hypoperfusion corresponding to the region in which the EEG showed abnormal findings, although magnetic resonance imaging (MRI) demonstrated no abnormal findings associated with the clinical features. Treatment with clonazepam in addition to sodium valproate resulted in a remarkable improvement of clinical symptoms (i.e. psychomotor seizures and deja vu), as well as of the EEG and SPECT findings. The present study suggests that SPECT is a useful method not only to determine the localization of regions associated with temporal lobe epilepsy but also to evaluate the effect of treatment in temporal lobe epilepsy.

Ageing and feature binding in visual working memory: The role of presentation time.

PubMed

Rhodes, Stephen; Parra, Mario A; Logie, Robert H

2016-01-01

A large body of research has clearly demonstrated that healthy ageing is accompanied by an associative memory deficit. Older adults exhibit disproportionately poor performance on memory tasks requiring the retention of associations between items (e.g., pairs of unrelated words). In contrast to this robust deficit, older adults' ability to form and temporarily hold bound representations of an object's surface features, such as colour and shape, appears to be relatively well preserved. However, the findings of one set of experiments suggest that older adults may struggle to form temporary bound representations in visual working memory when given more time to study objects. However, these findings were based on between-participant comparisons across experimental paradigms. The present study directly assesses the role of presentation time in the ability of younger and older adults to bind shape and colour in visual working memory using a within-participant design. We report new evidence that giving older adults longer to study memory objects does not differentially affect their immediate memory for feature combinations relative to individual features. This is in line with a growing body of research suggesting that there is no age-related impairment in immediate memory for colour-shape binding.

A Note on Trader Sharpe Ratios

PubMed Central

Coates, John M.; Page, Lionel

2009-01-01

Traders in the financial world are assessed by the amount of money they make and, increasingly, by the amount of money they make per unit of risk taken, a measure known as the Sharpe Ratio. Little is known about the average Sharpe Ratio among traders, but the Efficient Market Hypothesis suggests that traders, like asset managers, should not outperform the broad market. Here we report the findings of a study conducted in the City of London which shows that a population of experienced traders attain Sharpe Ratios significantly higher than the broad market. To explain this anomaly we examine a surrogate marker of prenatal androgen exposure, the second-to-fourth finger length ratio (2D∶4D), which has previously been identified as predicting a trader's long term profitability. We find that it predicts the amount of risk taken by traders but not their Sharpe Ratios. We do, however, find that the traders' Sharpe Ratios increase markedly with the number of years they have traded, a result suggesting that learning plays a role in increasing the returns of traders. Our findings present anomalous data for the Efficient Markets Hypothesis. PMID:19946367

Portuguese validation of the Internet Addiction Test: An empirical study

PubMed Central

PONTES, HALLEY M.; PATRÃO, IVONE M.; GRIFFITHS, MARK D.

2014-01-01

Background and aims: Research into Internet addiction (IA) has increased greatly over the last decade. Despite its various definitions and general lack of consensus regarding its conceptualisation amongst researchers, instruments for measuring this phenomenon have proliferated in a number of countries. There has been little research on IA in Portugal and this may be partly due to the absence of standardised measurement tools for assessing IA. Methods: This study attempted to address this issue by adapting a Portuguese version of the Internet Addiction Test (IAT) via a translation-back translation process and Confirmatory Factor Analysis in a sample of 593 Portuguese students that completed a Portuguese version of the IAT along with questions related to socio-demographic variables. Results: The findings suggested that the IAT appears to be a valid and reliable instrument for measuring IA among Portuguese young adults as demonstrated by its satisfactory psychometric properties. However, the present findings also suggest the need to reword and update some of the IAT’s items. Prevalence of IA found in the sample was 1.2% and is discussed alongside findings relating to socio-demographic correlates. Limitations and implications of the present study are also discussed. Conclusions: The present study calls for a reflection of the IAT while also contributing to a better understanding of the basic aspects of IA in the Portuguese community since many health practitioners are starting to realise that Internet use may pose a risk for some individuals.

The predictive value of physical examination findings in patients with suspected acute heart failure syndrome.

PubMed

Jang, Timothy B; Aubin, Chandra; Naunheim, Rosanne; Lewis, Lawrence M; Kaji, Amy H

2012-06-01

It can be difficult to differentiate acute heart failure syndrome (AHFS) from other causes of acute dyspnea, especially when patients present in extremis. The objective of the study was to determine the predictive value of physical examination findings for pulmonary edema and elevated B-type natriuretic peptide (BNP) levels in patients with suspected AHFS. This was a secondary analysis of a previously reported prospective study of jugular vein ultrasonography in patients with suspected AHFS. Charts were reviewed for physical examination findings, which were then compared to pulmonary edema on chest radiography (CXR) read by radiologists blinded to clinical information and BNP levels measured at presentation. The predictive value of every sign and combination of signs for pulmonary edema on CXR or an elevated BNP was poor. Since physical examination findings alone are not predictive of pulmonary edema or an elevated BNP, clinicians should have a low threshold for using CXR or BNP in clinical evaluation. This brief research report suggests that no physical examination finding or constellation of findings can be used to reliably predict pulmonary edema or an elevated BNP in patients with suspected AHFS.

We present subarcsecond 1.3 mm continuum ALMA observations toward the Orion Molecular Cloud 1 South (OMC-1S) region, down to a spatial resolution of 74 au, which reveal a total of 31 continuum sources. We also present subarcsecond 7 mm continuum VLA observations of the same region, which allow further study of fragmentation down to a spatial resolution of 40 au. By applying a method of “mean surface density of companions” we find a characteristic spatial scale at ∼560 au, and we use this spatial scale to define the boundary of 19 “cores” in OMC-1S as groupings of millimeter sources. We find an additional characteristic spatial scale at ∼2800 au, which is the typical scale of the filaments in OMC-1S, suggesting a two-level fragmentation process. We measured the fragmentation level within each core and find a higher fragmentation toward the southern filament. In addition, the cores of the southern filament are also the densest cores (within 1100 au) in OMC-1S. This is fully consistent with previous studies of fragmentation at spatial scales one order of magnitude larger, and suggests that fragmentation down to 40 au seems to be governed by thermal Jeans processes in OMC-1S.

Positive and Negative Affect During Sexual Activity: Differences Between Homosexual and Heterosexual Men and Women, With and Without Sexual Problems.

PubMed

Peixoto, Maria Manuela; Nobre, Pedro

2016-01-02

Empirical research suggests that emotional response during sexual activity discriminates between sexually functional and dysfunctional heterosexual men and women, with clinics presenting lower positive and higher negative affect. However, there is no evidence about the role of emotions in gay men and lesbian women with sexual problems. The present study analyzed affective states during sexual activity in homosexual and heterosexual men and women, with and without sexual problems. Participants in this study were 156 men and 168 women. A 2 (group) × 2 (sexual orientation) multivariate analysis of variance was performed. Participants completed a web-survey assessing sexual functioning and the Positive Affect-Negative Affect Scale. Findings indicated a main effect of group, with groups with sexual problems reporting significantly more negative and lower positive affect compared with men and women without sexual problems, regardless of sexual orientation. However, findings have also shown an interaction effect in the male sample with gay men, contrary to heterosexual men, reporting similar affective responses regardless of having a sexual dysfunction or not. Overall, findings emphasize the role of affective responses during sexual activity in men and women with sexual problems, suggesting the importance of addressing emotional responses in assessment and treatment of sexual problems in individuals with different sexual orientations.

We present Chandra and XMM-Newton X-ray observations of the Abell 3391/Abell 3395 intercluster filament. It has been suggested that the galaxy clusters Abell 3395, Abell 3391, and the galaxy group ESO-161 -IG 006 located between the two clusters, are in alignment along a large-scale intercluster filament. We find that the filament is aligned close to the plane of the sky, in contrast to previous results. We find a global projected filament temperature kT = {4.45}-0.55+0.89 keV, electron density {n}e={1.08}-0.05+0.06× {10}-4 cm‑3, and {M}gas}={2.7}-0.1+0.2 × {10}13 M ⊙. The thermodynamic properties of the filament are consistent with that of the intracluster medium (ICM) of Abell 3395 and Abell 3391, suggesting that the filament emission is dominated by ICM gas that has been tidally disrupted during an early stage merger between these two clusters. We present temperature, density, entropy, and abundance profiles across the filament. We find that the galaxy group ESO-161 may be undergoing ram-pressure-stripping in the low-density environment at or near the virial radius of both clusters, due to its rapid motion through the filament.

To analyze factors associated with progression of an original scientific presentation at the American Society of Pediatric Otolaryngology (ASPO) Annual Meeting to publication in a peer-reviewed journal. A dataset of presenters was created to enable prospective follow-up to assess early impressions regarding publication success with longer-term publication outcomes. Prior to the Annual ASPO meeting in 2013, a survey consisting of 10 questions was e-mailed to all 59 presenters. Questions were designed to assess presenter expectations on publication, barriers to publishing, and experience in presenting, publishing and clinical practice. A second survey was sent 12 months later to those respondents of the first survey who were amenable to follow-up. Overall, 46 of 59 (78%) presenters responded to the initial survey prior to their ASPO 2013 presentation. Of these, 34 agreed to participate in a longer-term follow-up of their presentation to publication experience. Of these 34, there were 17 who participated in the follow-up survey 1 year later. Just under half of the original respondents were residents (46%). All presenters (100%) planned to re-submit a revised manuscript if initially rejected. However, 35% of follow-up respondents did not make initial submission to a peer-reviewed journal. Results of a descriptive analysis suggest that more experienced researchers expect their submitted manuscript to be accepted for publication within a shorter time frame than those that have published fewer papers. Time was ranked as the greatest barrier to publication (60%) of those surveyed both in the initial prospective survey and for those who did not publish a paper in the follow-up survey (83%). This study suggests a strong desire and expectation of publishing ASPO presentations. Despite this expectation, past research and this data set suggest this expectation often does not materialize. "Time constraints" were the most commonly identified barrier to publication. To enhance dissemination of new findings from ASPO meetings, institutions and individuals should examine methods that facilitate and incentivize publication of findings in peer-reviewed publications.

Prior research suggests that reducing font clarity can cause people to consider printed information more carefully. The most famous demonstration showed that participants were more likely to solve counterintuitive math problems when they were printed in hard-to-read font. However, after pooling data from that experiment with 16 attempts to replicate it, we find no effect on solution rates. We examine potential moderating variables, including cognitive ability, presentation format, and experimental setting, but we find no evidence of a disfluent font benefit under any conditions. More generally, though disfluent fonts slightly increase response times, we find little evidence that they activate analytic reasoning. (c) 2015 APA, all rights reserved).

Vocational interests and career indecision among psychosis-prone college students.

Poreh, A M; Schullen, C

1998-10-01

This study investigated the relationship between scores on scales that purport to measure psychosis-proneness and scores on vocational interests, identity, and differentiation scales in a sample of 233 college students who completed the Perceptual Aberration and Magical Ideation scales, the Strong Campbell Interest Inventory, and the Career Decision Scale. The present findings are consistent with prior work indicating a sex-related association of scores on measures of psychosis-proneness and vocational interests. A positive correlation between scores on vocational indecision and measures of psychosis-proneness was also found, suggesting that both men and women who score high on psychosis-proneness find it difficult to formulate long-term career goals. Finally, there was no significant correlation between scores on measures of psychosis-proneness and Holland's Vocational Differentiation Index. Present results are discussed in light of previously reported sex differences among psychosis-prone adults and diagnosed schizophrenics. The implications of the findings for vocational counselors are also addressed.

Conservation and Evolutionary Dynamics of the agr Cell-to-Cell Communication System across Firmicutes▿ †

2008-01-01

We present evidence that the agr cell-to-cell communication system is present across firmicutes, including the human pathogen Clostridium perfringens. Although we find that the agr system is evolutionarily conserved and that the general functions which it regulates are similar in different species, the individual regulated genes are not the same. This suggests that the regulatory network controlled by agr is dynamic and evolves rapidly. PMID:17933897

2013-09-01

The evolutionary and biogeographic history of West Indian boid snakes (Epicrates), a group of nine species and 14 subspecies, was once thought to be well understood; however, new research has indicated that we are missing a clear understanding of the evolutionary relationships of this group. Here, we present the first multilocus, species-tree based analyses of the evolutionary relationships, divergence times, and historical biogeography of this clade with data from 10 genes and 6256 bp. We find evidence for a single colonization of the Caribbean from mainland South America in the Oligocene or early Miocene, followed by a radiation throughout the Greater Antilles and Bahamas. These findings support the previous suggestion that Epicrates sensu lato Wagler is paraphyletic with respect to the anacondas (Eunectes Wagler), and hence we restrict Epicrates to the mainland clade and use the available name Chilabothrus Duméril and Bibron for the West Indian clade. Our results suggest some diversification occurred within island banks, though most species divergence events seem to have occurred in allopatry. We also find evidence for a remarkable diversification within the Bahamian archipelago suggesting that the recognition of another Bahamian endemic species C. strigilatus is warranted.

The effect of morphological complexity on verbal working memory: results from Arabic speaking children.

2013-06-01

To examine the role of morphology in verbal working memory. Forty nine children, all native speakers of Arabic from the same region and of the same dialect, performed a Listening Word Span Task, whereby they had to recall Arabic uninflected words (i.e., base words), inflected words with regular (possessive) morphology, or inflected words with irregular (broken plural) morphology. Each of these words was at the end of a sentence (henceforth, target word). The participant's task was to listen to a series of sentences and then recall the target words. Recall of inflected words was significantly poorer than uninflected words, and recall of words with regular morphology was significantly poorer than recall of words with irregular morphology. These findings, albeit preliminary, suggest a role of morphology in verbal working memory. They also suggest that, at least in Arabic, regular morphological forms are decomposed into their component elements and hence impose an extra load on the central executive and episodic buffer components of working memory. Furthermore, in concert with findings from other studies, they suggest that the effect of morphology on working memory is probably language-specific. The clinical implications of the present findings are addressed.

Diffuse Lewy body disease: clinical features in 15 cases.

Byrne, E J; Lennox, G; Lowe, J; Godwin-Austen, R B

1989-01-01

Fifteen cases of diffuse Lewy body disease were diagnosed on pathological grounds during a single year in one health district. The range and frequency of clinical features contrast strikingly with previous reports. The majority of cases presented with classical levodopa-responsive Parkinson's disease either alone (6 cases) or with mild cognitive impairment (3 cases); the remaining 6 cases presented with cognitive impairment alone. In time almost all patients developed both dementia and Parkinsonism. The dementia was cortical in type, but unusual in that most (12 cases) showed day-to-day fluctuation in severity at some point in their illness. These findings suggest that diffuse Lewy body disease is not rare, and that it presents in a range of ways from dementia with subsequent Parkinsonism to Parkinson's disease with subsequent dementia. The latter mode of presentation suggests that it should be considered as a significant pathological substrate of dementia in Parkinson's disease. Images PMID:2545827

Lateralization of event-related potential effects during mental rotation of polygons.

PubMed

Pellkofer, Julia; Jansen, Petra; Heil, Martin

2012-07-11

Numerous studies have shown that there is an amplitude modulation of the late positivity depending on the angular disparity during mental rotation performance. However, almost all of these studies used characters as stimulus material, whereas studies with different stimuli are rare. In the present experiment, 35 participants were instructed to rotate polygons mentally. Most importantly, with this stimulus material, the well-known event-related potential effects were also present at posterior electrode leads. Interestingly, the amplitude modulation were found to be larger and more reliable over left than over right posterior electrode leads, a finding reported previously for characters as stimuli, although not consistently. Thus, the present data suggest that the left lateralization of event-related potential effects during mental rotation of characters might not be because of their 'verbal nature', but might suggest a stronger involvement of the left parietal cortex during mental rotation per se, a suggestion that needs to be addressed with methods providing a higher spatial resolution.

Improvement of nonsuicidal self-injury following treatment with antipsychotics possessing strong D1 antagonistic activity: evidence from a report of three cases.

PubMed

Wollweber, Bastian; Keck, Martin E; Schmidt, Ulrike

2015-08-01

There is no drug treatment for nonsuicidal self-injury (NSSI), a highly prevalent and burdensome symptom of several psychiatric diseases like posttraumatic stress disorder (PTSD), personality disorders, and major depression (MD). Here, we present a retrospective series of three patients demonstrating a persistent remission in MD-associated NSSI in response to treatment with antipsychotics possessing marked D1 receptor antagonistic activity. To the best of the authors' knowledge, the case series presented is only the second clinical paper suggesting a role for D1 antagonists in NSSI drug therapy. Together with previously published data from rodent models, the findings suggest a role for D1 antagonists in NSSI drug therapy and hence for the D1 receptor in NSSI pathogenesis. This conclusion is limited by the facts that the patients presented here received polypharmacy and that the D1 receptor antagonistic antipsychotics suggested here as effective 'anti-auto-aggressants' do not address D1 receptors only but multiple neurotransmitter receptors/systems.

Acquisition of generic memory in amnesia.

PubMed

Verfaellie, M; Cermak, L S

1994-06-01

Amnesic patients' ability to acquire generic, semantic information was assessed relative to their own level of episodic memory. Patients studied a list of words in which some items were presented twice and others once. Upon each presentation, the words were tagged episodically by presenting them in a unique color. Recall of the colors in which words were presented suggested that individual presentations of repeated items were less likely to be recalled than presentations of nonrepeated items; however, actual recall of repeated items exceeded that of nonrepeated items. This outcome demonstrated that amnesics can recall some items generically without recalling either of their individual presentations. However, amnesics' recall of twice-presented items remained far below that of the control group, even when their recall of once-presented items was matched by testing the control group after a delay. This finding suggests that amnesic patients can acquire new generic knowledge but do so much less efficiently than do normal individuals. Furthermore, this deficit occurs independently of the amnesics' episodic memory impairments, reflecting instead a disruption in semantic learning per se.

Hemispheric asymmetries in discourse processing: evidence from false memories for lists and texts.

PubMed

Ben-Artzi, Elisheva; Faust, Miriam; Moeller, Edna

2009-01-01

Previous research suggests that the right hemisphere (RH) may contribute uniquely to discourse and text processing by activating and maintaining a wide range of meanings, including more distantly related meanings. The present study used the word-lists false memory paradigm [Roediger, H. L., III, & McDermott, K. B. (1995). Creating false memories: Remembering words not presented in lists. Journal of Experimental Psychology: Learning, Memory, and Cognition, 21, 803-814.] to examine the hypothesis that difference between the two cerebral hemispheres in discourse processing may be due, at least partly, to memory representations for implicit text-related semantic information. Specifically, we tested the susceptibility of the left hemisphere (LH) and RH to unpresented target words following the presentation of semantically related words appearing in either word lists or short texts. Findings showed that the RH produced more false alarms than the LH for unpresented target words following either word lists or texts. These findings reveal hemispheric differences in memory for semantically related information and suggest that RH advantage in long-term maintenance of a wide range of text-related word meanings may be one aspect of its unique contribution to the construction of a discourse model. The results support the RH coarse semantic coding theory [Beeman, M. (1998). Coarse semantic coding and discourse comprehension. In M. Beeman & C. Chiarello (Eds.), Right hemisphere language comprehension: Perspectives from cognitive neuroscience (pp. 255-284). Mahwah, NJ: Erlbaum.] and suggest that hemispheric differences in semantic processing during language comprehension extend also to verbal memory.

The present study examined influences of 6 th grade student-reported parent educational involvement on early adolescent peer group affiliations at 7 th and 8 th grade. In addition, student gender and ethnicity were explored as possible moderators. Drawn from a large effectiveness trial, participants in this study were 5,802 early adolescents across twenty middle schools in the Northwest region of the United States. Findings suggested that specifically parent's educational involvement in 6 th grade predicted increases in positive peer affiliation, when controlling for a general score of parent monitoring practices. The relation between parent educational involvement and peer affiliation varied by student ethnicity but not by gender. Findings suggest the social benefits of parent's engagement with the school context on early adolescent development.

Decision processes in choice overload: a product of delay and probability discounting?

PubMed

Kaplan, Brent A; Reed, Derek D

2013-07-01

Recent research in the behavioral decision making literature has demonstrated that humans hyperbolically discount the subjective value of options as the number of options increases (Reed et al., 2012). These findings provide a cognitive-behavioral synthesis of the "choice overload" phenomenon, also known as the "paradox of choice." Specifically, these findings suggest that temporal discounting may serve as the underlying process contributing to this effect. As an extension, this study examined the effects of reward magnitude sizes had on rates temporal and options discounting. This manipulation was conducted to determine what role temporal discounting plays in discounting of options. The present results suggest that temporal discounting may not be the only process contributing to the choice overload effect. Copyright © 2013 Elsevier B.V. All rights reserved.

Cognitions and distress in caregivers after their child's sexual abuse disclosure.

Runyon, Melissa K; Spandorfer, Ellen D; Schroeder, Christine M

2014-01-01

The impact of child sexual abuse on children is well documented, but few studies have examined the impact of a child's sexual abuse disclosure on maternal caregivers. The studies that have been conducted suggest that parental response postdisclosure is variable. The present study examined the association between maternal attributions and abuse-specific cognitions with depression and trauma symptoms postdisclosure. Participants included 68 nonoffending maternal caregivers of children between the ages of 3 and 17 years who experienced child sexual abuse. Findings indicated that caregivers' abuse-specific cognitions were the best predictor of self-reported symptoms of depression after controlling for general negative attributions. These findings suggest that in order to reduce caregivers' distress and to enhance their support of their children, it is important to assess and treat caregivers' abuse-specific cognitions.

Interrogative suggestibility in opiate users.

1996-09-01

The present study investigated interrogative suggestibility in opiate users. A group of patients undergoing a methadone detoxification programme in an in-patient drug treatment unit (Detox group, n = 21), and a group of residents who had come off drugs and were no longer suffering from withdrawal syndrome (Rehab group, n = 19) were compared on interrogative suggestibility and various other psychological factors. Significant differences were found between the two groups, with the Detox group having more physical and psychological problems, and a higher total suggestibility score in comparison with the Rehab group. These findings are discussed in relation to the context of police interrogations and the reliability of confessions made by suspects and witnesses dependent on opiates.

Simple pebble tools, ephemeral cultural features, and the remains of maritime and terrestrial foods are present in undisturbed Late Pleistocene and Early Holocene deposits underneath a large human-made mound at Huaca Prieta and nearby sites on the Pacific coast of northern Peru. Radiocarbon ages indicate an intermittent human presence dated between ~15,000 and 8000 calendar years ago before the mound was built. The absence of fishhooks, harpoons, and bifacial stone tools suggests that technologies of gathering, trapping, clubbing, and exchange were used primarily to procure food resources along the shoreline and in estuarine wetlands and distant mountains. The stone artifacts are minimally worked unifacial stone tools characteristic of several areas of South America. Remains of avocado, bean, and possibly cultivated squash and chile pepper are also present, suggesting human transport and consumption. Our new findings emphasize an early coastal lifeway of diverse food procurement strategies that suggest detailed observation of resource availability in multiple environments and a knowledgeable economic organization, although technologies were simple and campsites were seemingly ephemeral and discontinuous. These findings raise questions about the pace of early human movement along some areas of the Pacific coast and the level of knowledge and technology required to exploit maritime and inland resources.

Common and distinct neural mechanisms of the fundamental dimensions of social cognition.

PubMed

Han, Mengfei; Bi, Chongzeng; Ybarra, Oscar

2016-01-01

In the present study, we used a valence classification task to investigate the common and distinct neural basis of the two fundamental dimensions of social cognition (agency and communion) using functional magnetic resonance imaging (fMRI). The results showed that several brain areas associated with mentalizing, along with the inferior parietal gyrus in the mirror system, showed overlap in response to both agentic and communal words. These findings suggest that both content categories are related to the neural basis of social cognition; further, several areas in the default mode network (DMN) showed similar deactivations between agency and communion, reflecting task-induced deactivation (TID). In terms of distinct activations, the findings indicated greater deactivations for communal than agentic content in the ventral anterior cingulate (vACC) and medial orbitofrontal cortex (mOFC). Communion also showed greater activation in some visual areas compared to agentic content, including occipital gyrus, lingual gyrus, and fusiform gyrus. These activations may reflect greater allocation of attentional resources to visual areas when processing communal content, or inhibition of cognitive activity irrelevant to task performance. If so, this suggests greater attention and engagement with communion-related content. The present research thus suggests common and differential activations for agency- versus communion-related content.

Clarifying the relation between spirituality and well-being.

PubMed

Migdal, Lori; MacDonald, Douglas A

2013-04-01

Koenig (J Nerv Ment Dis 196:349-355, 2008) and others have asserted that measures of spirituality used to investigate its association with health seem to present a misleading picture of the relationship because of evidence suggesting that spirituality has become conceptually confounded with well-being. To evaluate this claim, the present study used a sample of 247 university students to explore the relation of a multidimensional model of spirituality with several different forms of well-being and the association of both with a two-factor model of social desirability. Correlational and regression analyses revealed that, although there is some evidence of an association, it is generally of low effect size and seems to differ as a function of how spirituality is defined. More importantly, however, there was the finding that existential well-being, a concept often incorporated into definitions of spirituality and a part of the measurement model used in this study, is virtually uncorrelated with explicitly spiritual and religious variables but shows a pattern of association with measures of well-being and social desirability, which suggests that it would be better conceptualized as a form of well-being and not spirituality. The article concludes with a discussion of the meaning of the findings for understanding the spirituality-health literature and suggestions for future research.

The neural basis of cultural differences in delay discounting

PubMed Central

Kim, Bokyung; Sung, Young Shin; McClure, Samuel M.

2012-01-01

People generally prefer to receive rewarding outcomes sooner rather than later. Such preferences result from delay discounting, or the process by which outcomes are devalued for the expected delay until their receipt. We investigated cultural differences in delay discounting by contrasting behaviour and brain activity in separate cohorts of Western (American) and Eastern (Korean) subjects. Consistent with previous reports, we find a dramatic difference in discounting behaviour, with Americans displaying much greater present bias and elevated discount rates. Recent neuroimaging findings suggest that differences in discounting may arise from differential involvement of either brain reward areas or regions in the prefrontal and parietal cortices associated with cognitive control. We find that the ventral striatum is more greatly recruited in Americans relative to Koreans when discounting future rewards, but there is no difference in prefrontal or parietal activity. This suggests that a cultural difference in emotional responsivity underlies the observed behavioural effect. We discuss the implications of this research for strategic interrelations between Easterners and Westerners. PMID:22271781

Finding Your Literature Match - A Physics Literature Recommender System

2010-03-01

A recommender system is a filtering algorithm that helps you find the right match by offering suggestions based on your choices and information you have provided. A latent factor model is a successful approach. Here an item is characterized by a vector describing to what extent a product is described by each of N categories, and a person is characterized by an ``interest'' vector, based on explicit or implicit feedback by this user. The recommender system assigns ratings to new items and suggests items this user might be interested in. Here we present results of a recommender system designed to find recent literature of interest to people working in the field of solid state physics. Since we do not have explicit feedback, our user vector consists of (implicit) ``usage.'' Using a system of N keywords we construct normalized keyword vectors for articles based on the keywords of that article and its bibliography. The normalized ``interest'' vector is created by calculating the normalized frequency of keyword occurrence in the papers cited by the papers read.

Re-thinking HIV-Related Stigma in Health Care Settings: A Qualitative Study.

PubMed

Gagnon, Marilou

2015-01-01

People living with HIV (PLWH) continue to endure stigma and discrimination in the context of health care. This paper presents the findings of a qualitative study designed to (a) describe stigmatizing and discriminatory practices in health care settings, and (b) explore both symbolic and structural stigma from the perspectives of PLWH. For the purpose of this qualitative study, 21 semi-structured in-depth interviews were conducted in the province of Quebec, Canada. The data were analyzed following the principles of thematic analysis. During analysis, three themes were identified, and relations between these themes were delineated to reflect the experiences of participants. The findings suggest that HIV-related stigma in health care settings is episodic in nature. The findings also suggest that HIV-related stigma is experienced through interactions with health care providers (symbolic stigma) and, finally, that it is applied systematically to manage risk in the context of health care (structural stigma).

Nursing clinical developments units--A strategy to promote the relationship between practice and academia.

Happell, Brenda

2006-05-01

Bridging the theory-practice gap has historically been acknowledged as a priority for the nursing profession. Enhancing nurses' attitudes regarding the relevance of theory to practice has been considered as crucial in order that the relationship between theory and practice becomes strong and complimentary. A review of the literature suggests that strategies such as joint clinical and academic positions have not had a significant impact in this respect. Nursing Clinical Development Units (NCDUs) were introduced in the United Kingdom as an initiative to promote the recognition and utilisation of research findings as an inherent component of nursing practice. However, there is limited literature addressing the impact of NCDUs on relationships between academia and the clinical field. The aim of this paper is to present the findings of a qualitative evaluation conducted with participants (n=14) of an NCDU program in Victoria, Australia. The findings suggest that this initiative can significantly enhance relationships with, and attitudes towards, academia.

Getting older, feeling less? A cross-sectional and longitudinal investigation of developmental patterns in experiential well-being

PubMed Central

Hudson, Nathan W.; Lucas, Richard E.; Donnellan, M. Brent

2016-01-01

A large body of previous research suggests that people’s global evaluations of their well-being tend to increase as a function of age. Fewer studies, however, have examined the extent to which people’s in vivo experiences of well-being (e.g., felt emotions) vary as a function of age—and the existing findings are mixed. The present study used an approximately nationally representative sample of more than 2,500 Germans to evaluate developmental patterns in both experiential and global well-being using cross-sectional and longitudinal analyses. The cross-sectional and longitudinal findings converged on the idea that affect—whether positive or negative, global or experiential—decreases as a function of age and time. In contrast, life satisfaction appears to remain consistent, or perhaps decline across midlife before rebounding in old age. These findings suggest that affective well-being may develop in a nuanced way across adulthood: Negative affect appears to ebb with age—but so does positive affect. PMID:27929340

Many children show negative emotions related to mathematics and some even develop mathematics anxiety. The present study focused on the relation between negative emotions and arithmetical performance in children with and without developmental dyscalculia (DD) using an affective priming task. Previous findings suggested that arithmetic performance is influenced if an affective prime precedes the presentation of an arithmetic problem. In children with DD specifically, responses to arithmetic operations are supposed to be facilitated by both negative and mathematics-related primes (= negative math priming effect ).We investigated mathematical performance, math anxiety, and the domain-general abilities of 172 primary school children (76 with DD and 96 controls). All participants also underwent an affective priming task which consisted of the decision whether a simple arithmetic operation (addition or subtraction) that was preceded by a prime (positive/negative/neutral or mathematics-related) was true or false. Our findings did not reveal a negative math priming effect in children with DD. Furthermore, when considering accuracy levels, gender, or math anxiety, the negative math priming effect could not be replicated. However, children with DD showed more math anxiety when explicitly assessed by a specific math anxiety interview and showed lower mathematical performance compared to controls. Moreover, math anxiety was equally present in boys and girls, even in the earliest stages of schooling, and interfered negatively with performance. In conclusion, mathematics is often associated with negative emotions that can be manifested in specific math anxiety, particularly in children with DD. Importantly, present findings suggest that in the assessed age group, it is more reliable to judge math anxiety and investigate its effects on mathematical performance explicitly by adequate questionnaires than by an affective math priming task.

Ocular manifestations of sarcoidosis in children are the second most common occurrence after hilar adenopathy and pulmonary abnormalities. We present the case history of a 14-year-old black boy who presented with redness of the left eye, blurred vision, and decreased visual acuity. He was subsequently diagnosed as having sarcoidosis. All patients with uveitis or ocular findings suggestive of sarcoidosis should have a through medical examination and a chest x-ray. Those suspected of or proven to have sarcoidosis should have a complete ophthalmological examination. Sarcoidosis in children appears to be more frequent than previously estimated.

Electromagnetic compatibility and safety design of a patient compliance-free, inductive implant charger.

This article presents the design of a domestic, radiofrequency induction charger for implants toward compliance with the Federal Communications Commission safety and electromagnetic compatibility regulations. The suggested arrangement does not impose any patient compliance requirements other than the use of a designated bed for night sleep, and therefore can find a domestic use. The method can be applied to a number of applications; a rechargeable pacemaker is considered as a case study. The presented work has proven that it is possible to realize a fully compliant inductive charging system with minimal patient interaction, and has generated important information for consideration by the designers of inductive charging systems. Experimental results have verified the validity of the theoretical findings.

Unusual MRI findings in an immunocompetent patient with EBV encephalitis: a case report

PubMed Central

2011-01-01

Blackground It is well-known that Epstein-Barr virus (EBV) can affect the central nervous system (CNS). Case presentation Herein the authors report unusual timely Magnetic Resonance Imaging (MRI) brain scan findings in an immunocompetent patient with EBV encephalitis. Diffusion weighted MRI sequence performed during the acute phase of the disease was normal, whereas the Fast Relaxation Fast Spin Echo T2 image showed diffuse signal intensity changes in white matter. The enhancement pattern suggested an inflammatory response restricted to the brain microcirculation. Acyclovir and corticosteroid therapy was administered. After three weeks, all signal intensities returned to normal and the patient showed clinical recovery. Conclusion This report demonstrates that EBV in an immunocompetent adult can present with diffuse, reversible brain white matter involvement in the acute phase of mononucleosis. Moreover, our case suggests that a negative DWI sequence is associated with a favorable improvement in severe EBV CNS infection. More extensive studies are needed to assess what other instrumental data can help to distinguish viral lesions from other causes in the acute phase of disease. PMID:21435249

Taxonomic and ad hoc categorization within the two cerebral hemispheres.

PubMed

Shen, Yeshayahu; Aharoni, Bat-El; Mashal, Nira

2015-01-01

A typicality effect refers to categorization which is performed more quickly or more accurately for typical than for atypical members of a given category. Previous studies reported a typicality effect for category members presented in the left visual field/right hemisphere (RH), suggesting that the RH applies a similarity-based categorization strategy. However, findings regarding the typicality effect within the left hemisphere (LH) are less conclusive. The current study tested the pattern of typicality effects within each hemisphere for both taxonomic and ad hoc categories, using words presented to the left or right visual fields. Experiment 1 tested typical and atypical members of taxonomic categories as well as non-members, and Experiment 2 tested typical and atypical members of ad hoc categories as well as non-members. The results revealed a typicality effect in both hemispheres and in both types of categories. Furthermore, the RH categorized atypical stimuli more accurately than did the LH. Our findings suggest that both hemispheres rely on a similarity-based categorization strategy, but the coarse semantic coding of the RH seems to facilitate the categorization of atypical members.

Dynamic scaling in natural swarms

NASA Astrophysics Data System (ADS)

Cavagna, Andrea; Conti, Daniele; Creato, Chiara; Del Castello, Lorenzo; Giardina, Irene; Grigera, Tomas S.; Melillo, Stefania; Parisi, Leonardo; Viale, Massimiliano

2017-09-01

Collective behaviour in biological systems presents theoretical challenges beyond the borders of classical statistical physics. The lack of concepts such as scaling and renormalization is particularly problematic, as it forces us to negotiate details whose relevance is often hard to assess. In an attempt to improve this situation, we present here experimental evidence of the emergence of dynamic scaling laws in natural swarms of midges. We find that spatio-temporal correlation functions in different swarms can be rescaled by using a single characteristic time, which grows with the correlation length with a dynamical critical exponent z ~ 1, a value not found in any other standard statistical model. To check whether out-of-equilibrium effects may be responsible for this anomalous exponent, we run simulations of the simplest model of self-propelled particles and find z ~ 2, suggesting that natural swarms belong to a novel dynamic universality class. This conclusion is strengthened by experimental evidence of the presence of non-dissipative modes in the relaxation, indicating that previously overlooked inertial effects are needed to describe swarm dynamics. The absence of a purely dissipative regime suggests that natural swarms undergo a near-critical censorship of hydrodynamics.

Conservative cricoid surgery for chondrosarcoma: a case report.

PubMed

Gaio, Elena; Maggiore, Giandomenico; Canesso, Alessandra; Artico, Riccardo

2014-02-01

We present the case of a 39-year-old man who presented with hoarseness and progressively worsening dyspnea. Findings on laryngoscopy and computed tomography strongly suggested the presence of a chondrosarcoma. The patient underwent open surgery for removal of the lesion with wide margins. Reconstruction was carried out with two segments of costal cartilage. Laryngeal chondrosarcomas are rare, malignant, usually well-differentiated neoplasms that should be treated with conservative surgery. Recurrences should be treated more aggressively.

Recombinative Generalization: An Exploratory Study in Musical Reading

PubMed Central

Perez, William Ferreira; de Rose, Julio C

2010-01-01

The present study aimed to extend the findings of recombinative generalization research in alphabetical reading and spelling to the context of musical reading. One participant was taught to respond discriminatively to six two-note sequences, choosing the corresponding notation on the staff in the presence of each sequence. When novel three- and four-note sequences were presented, she selected the corresponding notation. These results suggest the generality of previous research to the context of musical teaching.

Domestic violence and mental health in older adults.

PubMed

Knight, Lucy; Hester, Marianne

2016-10-01

Domestic violence affects every age group and is present throughout the life span, but, while the mental health impact of domestic violence is clearly established in working age adults, less is known about the nature and impact of domestic violence among older adults. This review, therefore, aimed to synthesize findings on the prevalence, nature, and impact of domestic violence among older adults, and its identification and management. Electronic searches were conducted of Medline, PsycINFO, Cinahl, and Embase to identify studies reporting on the mental health and domestic violence in older adults. Findings suggested that, although prevalence figures are variable, the likely lifetime prevalence for women over the age of 65 is between 20-30%. Physical abuse is suggested to decrease with age, but rates of emotional abuse appear to be stable over the lifespan. Among older adults, domestic violence is strongly associated with physical and mental health problems, and the scarce research comparing the impact of domestic violence across the age cohorts suggests that the physical health of older victims may be more severely affected than younger victims. In contrast, there is evidence that older victims may experience less psychological distress in response to domestic violence than younger victims. Internationally, evidence on the management of domestic violence in older adults is sparse. Findings suggest, however, that identification of domestic violence is poor among older adults, and there are very limited options for onwards referral and support.

Fossil Find on Svalbard Highlights the Natural History of the Polar Bear (Ursus maritimus)

NASA Astrophysics Data System (ADS)

Ingolfsson, O.; Wiig, O.

2007-12-01

During recent fieldwork on Svalbard a well preserved subfossil left ramus of a polar bear (Ursus maritimus) mandible was discovered. A 14C age determination shows that it is older than 45 ka (kilo-years), and an OSL (Optical Stimulated Luminescence) age determination together with the stratigraphic position of the bone suggests that it is of Eemian-Early Weichselian/Wisconsinan age, 150-80 ka old. This puts the find among the oldest fossil remains of a polar bear ever discovered. Osteological study of the mandible suggests that it comes from a fully grown female. The fossil record suggests that polar bears may have developed from brown bears during the early part of the last glacial cycle, some 100 ka ago. The present interglacial might be the first such that the species has to endure. This underlines the potential status of the polar bears as an endangered species if the current warming trend and diminishing of sea ice cover in the Arctic continues.

Differentiated thyroid carcinoma with functional autonomy.

PubMed

Yaturu, Subhashini; Fowler, Marjorie R

2002-01-01

To present a case of papillary carcinoma in an autonomously hyperfunctioning thyroid nodule. We chronicle the clinical and laboratory findings in a patient with a painless neck mass, with a particular focus on the pathologic findings after surgical removal of the right thyroid lobe. A 39-year-old woman had an enlarging nodule of the right thyroid lobe. Results of thyroid function tests suggested subclinical hyperthyroidism. Two months later, the patient complained of increasing swelling in the neck (but still had no symptoms suggestive of hyperthyroidism). Thus, resection of the right thyroid lobe was performed. Pathologic analysis disclosed low-grade papillary thyroid carcinoma within the nodule, with a small rim of compressed inactive-appearing thyroid tissue surrounding the nodule. Subsequently, she underwent total thyroidectomy and follow-up care for thyroid carcinoma. Although solitary hyperfunctioning nodules of the thyroid gland are usually considered benign, the current case suggests that the diagnosis of autonomous thyroid nodules does not preclude thyroid carcinoma in a functioning nodule.

Memory for product sounds: the effect of sound and label type.

PubMed

Ozcan, Elif; van Egmond, René

2007-11-01

The (mnemonic) interactions between auditory, visual, and the semantic systems have been investigated using structurally complex auditory stimuli (i.e., product sounds). Six types of product sounds (air, alarm, cyclic, impact, liquid, mechanical) that vary in spectral-temporal structure were presented in four label type conditions: self-generated text, text, image, and pictogram. A memory paradigm that incorporated free recall, recognition, and matching tasks was employed. The results for the sound type suggest that the amount of spectral-temporal structure in a sound can be indicative for memory performance. Findings related to label type suggest that 'self' creates a strong bias for the retrieval and the recognition of sounds that were self-labeled; the density and the complexity of the visual information (i.e., pictograms) hinders the memory performance ('visual' overshadowing effect); and image labeling has an additive effect on the recall and matching tasks (dual coding). Thus, the findings suggest that the memory performances for product sounds are task-dependent.

Implicit theories of a desire for fame.

PubMed

Maltby, John; Day, Liz; Giles, David; Gillett, Raphael; Quick, Marianne; Langcaster-James, Honey; Linley, P Alex

2008-05-01

The aim of the present studies was to generate implicit theories of a desire for fame among the general population. In Study 1, we were able to develop a nine-factor analytic model of conceptions of the desire to be famous that initially comprised nine separate factors; ambition, meaning derived through comparison with others, psychologically vulnerable, attention seeking, conceitedness, social access, altruistic, positive affect, and glamour. Analysis that sought to examine replicability among these factors suggested that three factors (altruistic, positive affect, and glamour) neither display factor congruence nor display adequate internal reliability. A second study examined the validity of these factors in predicting profiles of individuals who may desire fame. The findings from this study suggested that two of the nine factors (positive affect and altruism) could not be considered strong factors within the model. Overall, the findings suggest that implicit theories of a desire for fame comprise six factors. The discussion focuses on how an implicit model of a desire for fame might progress into formal theories of a desire for fame.

Laryngeal juvenile xanthogranuloma: Imaging finding.

PubMed

Wang, L M; Chen, Q H; Zhang, Y X; Fang, Y Q

2010-08-01

Laryngeal juvenile xanthogranuloma is rare and there were only four cases have been reported previously in English literature. We report a case of isolated JXG of larynx in the superglottic region. The mass was well-defined and homogeneous hypoechoic in ultrasonography while presented indistinct boundary and soft tissue density in Computed Tomography images. Radiological findings are nonspecific but could help to understand the extent of the lesion. We suggest that JXG should be considered as differential diagnosis for laryngeal stridor. Laryngeal ultrasound is safe and reliable, which could be considered a useful diagnostic tool for supplementing laryngoscopy.

2017-10-01

I will present results from the 1.5Ms XMM-Newton observing campaign on the most X-ray variable AGN, IRAS 13224-3809. We find a series of nine absorption lines with a velocity of 0.24c from an ultra-fast outflow. For the first time, we are able to see extremely rapid variability of the UFO features, and can link this to the X-ray variability from the inner accretion disk. We find a clear flux dependence of the outflow features, suggesting that the wind is ionized by increasing X-ray emission.

Early data from clinical studies suggest that intracoronary injection of autologous progenitor cells may beneficially affect postinfarction remodeling and perfusion. Beyond intracoronary infusion of autologous bone marrow mononuclear CD34+ cells (MNCCD34+), mobilization of stem cells by G-CSF has recently attracted attention because of various advantages such as the noninvasive nature of MNCCD34+ mobilization by subcutaneous injections. It is the aim of the present work to give an overview about the current experimental and clinical findings of G-CSF treatment in acute myocardial infarction.

Pai syndrome is a rare disorder characterized by congenital nasal or facial polyp, midline cleft lip, pericallosal lipoma, ocular anomalies, and normal neuropsychological development. Here, we report on three patients with Pai syndrome and atypical findings: temporal triangular alopecia, posterior lenticonus, bilateral palatal pits, bifid uvula, hypospadias, sacral dimple, true tracheal bronchus, and epilepsy. Thirty-three cases of Pai syndrome have been described so far. We present a review of the previously reported cases and suggest modified diagnostic criteria for Pai syndrome.

This paper presents literature reviews that show variety of techniques to develop parallel feature extractor and finding its correlation with noise reduction approaches for low light intensity images. Low light intensity images are normally displayed as darker images and low contrast. Without proper handling techniques, those images regularly become evidences of misperception of objects and textures, the incapability to section them. The visual illusions regularly clues to disorientation, user fatigue, poor detection and classification performance of humans and computer algorithms. Noise reduction approaches (NR) therefore is an essential step for other image processing steps such as edge detection, image segmentation,more » image compression, etc. Parallel Feature Extractor (PFE) meant to capture visual contents of images involves partitioning images into segments, detecting image overlaps if any, and controlling distributed and redistributed segments to extract the features. Working on low light intensity images make the PFE face challenges and closely depend on the quality of its pre-processing steps. Some papers have suggested many well established NR as well as PFE strategies however only few resources have suggested or mentioned the correlation between them. This paper reviews best approaches of the NR and the PFE with detailed explanation on the suggested correlation. This finding may suggest relevant strategies of the PFE development. With the help of knowledge based reasoning, computational approaches and algorithms, we present the correlation study between the NR and the PFE that can be useful for the development and enhancement of other existing PFE.« less

Leave Her out of It: Person-Presentation of Strategies is Harmful for Transfer.

Riggs, Anne E; Alibali, Martha W; Kalish, Charles W

2015-11-01

A common practice in textbooks is to introduce concepts or strategies in association with specific people. This practice aligns with research suggesting that using "real-world" contexts in textbooks increases students' motivation and engagement. However, other research suggests this practice may interfere with transfer by distracting students or leading them to tie new knowledge too closely to the original learning context. The current study investigates the effects on learning and transfer of connecting mathematics strategies to specific people. A total of 180 college students were presented with an example of a problem-solving strategy that was either linked with a specific person (e.g., "Juan's strategy") or presented without a person. Students who saw the example without a person were more likely to correctly transfer the novel strategy to new problems than students who saw the example presented with a person. These findings are the first evidence that using people to present new strategies is harmful for learning and transfer. Copyright © 2015 Cognitive Science Society, Inc.

Three-year-olds obey the sample size principle of induction: the influence of evidence presentation and sample size disparity on young children's generalizations.

PubMed

Lawson, Chris A

2014-07-01

Three experiments with 81 3-year-olds (M=3.62years) examined the conditions that enable young children to use the sample size principle (SSP) of induction-the inductive rule that facilitates generalizations from large rather than small samples of evidence. In Experiment 1, children exhibited the SSP when exemplars were presented sequentially but not when exemplars were presented simultaneously. Results from Experiment 3 suggest that the advantage of sequential presentation is not due to the additional time to process the available input from the two samples but instead may be linked to better memory for specific individuals in the large sample. In addition, findings from Experiments 1 and 2 suggest that adherence to the SSP is mediated by the disparity between presented samples. Overall, these results reveal that the SSP appears early in development and is guided by basic cognitive processes triggered during the acquisition of input. Copyright © 2013 Elsevier Inc.

Hypnotic suggestibility predicts the magnitude of the imaginative word blindness suggestion effect in a non-hypnotic context.

PubMed

Parris, Benjamin A; Dienes, Zoltan

2013-09-01

The present study investigated how the magnitude the word blindness suggestion effect on Stroop interference depended on hypnotic suggestibility when given as an imaginative suggestion (i.e. not post-hypnotic suggestion) and under conditions in which hypnosis was not mentioned. Hypnotic suggestibility is shown to be a significant predictor of the magnitude of the imaginative word blindness suggestion effect under these conditions. This is therefore the first study to show a linear relationship between the imaginative word blindness suggestion effect and hypnotic suggestibility across the whole hypnotizability spectrum. The results replicate previous findings showing that highs respond to the word blindness suggestion to a greater extent than lows but extend previous work by showing that the advantage for those higher on the hypnotizability spectrum occurs even in a non-hypnotic context. Negative attitudes about hypnosis may not explain the failure to observe similar effects of the word blindness suggestion in less hypnotizable individuals. Copyright © 2013 Elsevier Inc.

Global pathways to men's caregiving: mixed methods findings from the International Men and Gender Equality Survey and the Men Who Care study.

2014-01-01

Promoting men's participation in unpaid care work is part of the Programme of Action for the International Conference on Population and Development. However, men's involvement in care work does not mirror the advances women have made in paid work outside the home. This mixed method study explores which men are more involved in caregiving, and what childhood and adulthood factors influence their level of involvement. Quantitative research presents findings from 1169 men across six countries with children aged 0-4, and a qualitative study presents findings from in-depth interviews with 83 men engaged in atypical caregiving practices. Survey research finds that being taught to care for children, witnessing one's father take care of one's siblings, respondents' present attitudes about gender equality and having outside help (or none, in some cases) were all also associated with men's higher level of involvement. Qualitative research reveals that men's experiences of violence, the normalisation of domestic work as children and life circumstances rather than greater-than-average beliefs in gender equality all propelled them into care work. Findings suggest that engaging more men into care work implies changes to policies and structural realities in the workplace coupled with changing gender attitudes. These insights inform policy and practice aimed at promoting greater involvement in care work by men.

Declining Orangutan Encounter Rates from Wallace to the Present Suggest the Species Was Once More Abundant

Meijaard, Erik; Welsh, Alan; Ancrenaz, Marc; Wich, Serge; Nijman, Vincent; Marshall, Andrew J.

2010-01-01

Background Bornean orangutans (Pongo pygmaeus) currently occur at low densities and seeing a wild one is a rare event. Compared to present low encounter rates of orangutans, it is striking how many orangutan each day historic collectors like Alfred Russel Wallace were able to shoot continuously over weeks or even months. Does that indicate that some 150 years ago encounter rates with orangutans, or their densities, were higher than now? Methodology/Principal Findings We test this hypothesis by quantifying encounter rates obtained from hunting accounts, museum collections, and recent field studies, and analysing whether there is a declining trend over time. Logistic regression analyses of our data support such a decline on Borneo between the mid-19th century and the present. Even when controlled for variation in the size of survey and hunting teams and the durations of expeditions, mean daily encounter rates appear to have declined about 6-fold in areas with little or no forest disturbance. Conclusions/Significance This finding has potential consequences for our understanding of orangutans, because it suggests that Bornean orangutans once occurred at higher densities. We explore potential explanations—habitat loss and degradation, hunting, and disease—and conclude that hunting fits the observed patterns best. This suggests that hunting has been underestimated as a key causal factor of orangutan density and distribution, and that species population declines have been more severe than previously estimated based on habitat loss only. Our findings may require us to rethink the biology of orangutans, with much of our ecological understanding possibly being based on field studies of animals living at lower densities than they did historically. Our approach of quantifying species encounter rates from historic data demonstrates that this method can yield valuable information about the ecology and population density of species in the past, providing new insight into species' conservation needs.

Interaction of prime and target in the subliminal affective priming effect.

2003-04-01

It has been found that an emotional stimulus such as a facial expression presented subliminally can affect subsequent information processing and behavior, usually by shifting evaluation of a subsequent stimulus to a valence congruent with the previous stimulus. This phenomenon is called subliminal affective priming. The present study was conducted to replicate and expand previous findings by investigating interaction of primes and targets in the affective priming effect. Two conditions were used. Prime (subliminal presentation 35 msec.) of an angry face of a woman and a No Prime control condition. Just after presentation of the prime, an ambiguous angry face or an emotionally neutral face was presented above the threshold of awareness (500 msec.). 12 female undergraduate women judged categories of facial expressions (Anger, Neutral, or Happiness) for the target faces. Analysis indicated that the Anger primes significantly facilitated judgment of anger for the ambiguous angry faces; however, the priming effect of the Anger primes was not observed for neutral faces. Consequently, the present finding suggested that a subliminal affective priming effect should be more prominent when affective valence of primes and targets is congruent.

Community Peer-Led Falls Prevention Presentations: What Do the Experts Suggest?

Falls among older adults are a major problem. Despite considerable progress in falls prevention research, older adults often show low motivation to engage in recommended preventive strategies. Peer-led falls prevention education for older adults may have potential for bridging the research evidence-practice gap, thereby promoting the uptake of falls prevention strategies. We evaluated peer educators' presentations of falls prevention education to community-dwelling older adults in regard to established criteria that were consistent with adult learning principles, the framework of health behaviour change, falls prevention guidelines, and recommendations for providing falls prevention information. We conducted a within-stage mixed model study using purposive and snowball sampling techniques to recruit 10 experts to evaluate video recordings of the delivery of three peer-led falls prevention presentations. Each expert viewed three videos and rated them using a questionnaire containing both open-ended and closed items. There was a good level of expert agreement across the questionnaire domains. Though the experts rated some aspects of the presentations highly, they thought that the presentations were mainly didactic in delivery, not consistently personally relevant to the older adult audience, and did not encourage older adults to engage in the preventive strategies that were presented. Based on the experts' findings, we developed five key themes and recommendations for the effective delivery of peer-led falls prevention presentations. These included recommending that peer educators share falls prevention messages in a more interactive and experiential manner and that uptake of strategies should be facilitated by encouraging the older adults to develop a personalised action plan. Findings suggest that if peer-led falls prevention presentations capitalise on older adults' capability, opportunity, and motivation, the older adults may be more receptive to take up falls prevention messages.

Is evaluative conditioning really resistant to extinction? Evidence for changes in evaluative judgements without changes in evaluative representations.

PubMed

Gawronski, Bertram; Gast, Anne; De Houwer, Jan

2015-01-01

Evaluative conditioning (EC) is defined as the change in the evaluation of a conditioned stimulus (CS) due to its pairing with a positive or negative unconditioned stimulus (US). Although several individual studies suggest that EC is unaffected by unreinforced presentations of the CS without the US, a recent meta-analysis indicates that EC effects are less pronounced for post-extinction measurements than post-acquisition measurements. The disparity in research findings suggests that extinction of EC may depend on yet unidentified conditions. In an attempt to uncover these conditions, three experiments (N = 784) investigated the influence of unreinforced post-acquisition CS presentations on EC effects resulting from simultaneous versus sequential pairings and pairings with single versus multiple USs. For all four types of CS-US pairings, EC effects on self-reported evaluations were reduced by unreinforced CS presentations, but only when the CSs had been rated after the initial presentation of CS-US pairings. EC effects on an evaluative priming measure remained unaffected by unreinforced CS presentations regardless of whether the CSs had been rated after acquisition. The results suggest that reduced EC effects resulting from unreinforced CS presentations are due to judgement-related processes during the verbal expression of CS evaluations rather than genuine changes in the underlying evaluative representations.

Sex and hemisphere differences when mentally rotating meaningful and meaningless stimuli.

PubMed

Rilea, Stacy L

2008-05-01

The purpose of the current study was to investigate the influence of stimulus type and sex on strategy use and hemispheric processing during the mental rotation task. Participants included 67 right-handed men and women who completed three mental rotation tasks, all presented bilaterally. Participants rotated human stick figures, alphanumeric stimuli, and a two-dimensional (2D) meaningless object. No hemispheric differences were observed when rotating human stick figures, suggesting that men and women may rely on the same strategy. A left hemisphere advantage was observed in women when rotating alphanumeric stimuli, suggesting they may be relying on a verbal strategy, whereas no hemispheric differences were observed for men. Finally, inconsistent with predictions, no hemisphere differences were observed when rotating two-dimensional objects. The findings from the current study suggest that both the meaningfulness and the type of stimulus presented may influence strategy use differently for men and women.

Syndromic odontogenic keratocyst: A case report and review of literature

2016-01-01

Odontogenic keratocysts (OKCs) may occur in two different forms, either as solitary (nonsyndromic OKCs) or as multiple OKCs (syndromic OKCs). Multiple OKCs usually occur as one of the findings in Gorlin–Goltz syndrome with other features such as skin carcinomas and rib, eye, and neurologic abnormalities. We report a rare case of Gorlin–Goltz syndrome in a 20-year-old male patient who presented with a slow growing swelling on lower right and left back teeth region since 2 months. Apart from these, other findings were frontal bossing, depressed nasal bridge, ocular hypertelorism, prominent supra orbital ridge, and mild mandibular prognathism. Excision was done and microscopic study revealed OKC and the follow-up could not be carried out for the complete management. We also presented a review of its pathogenesis, criterion, and differences between syndromic and nonsyndromic OKCs and suggest to thoroughly examine any patient who presents with multiple OKCs to rule out syndromic variety.

The work of Galileo and conformation of the experiment in physics

It is very frequent to find comments and references to Galileo's work suggesting that he based his affirmations on a logic thought and not on observations. In this paper we present an analysis of some experiments that he realized and were unknown in the XVI and XVII centuries; in they we find a clear description of the methodology that Galileo follows in order to reach the results that he presents in his formal work, particularly in Discorsi. In contrast with the Aristotelian philosophy, in these manuscripts Galileo adopt a methodology with which he obtain great contributions for the modem conformation of the experimental method, founding so a methodology for the study of the movement. We use this analysis as an example of the difficulties that are present in the conformation of the modem experimentation and we point out the necessity to stress the importance of the scientific methodology in the teaching of physics.

Reduction and elimination of format effects on recall.

2008-01-01

Two experiments investigated whether the recall advantage of pictures and spoken words over printed words in working memory (Foos & Goolkasian, 2005; Goolkasian & Foos, 2002) could be reduced by manipulating letter case and sequential versus simultaneous presentation. Participants were required to remember 3 or 6 items presented in varied presentation formats while verifying the accuracy of a sentence. Presenting words in alternating uppercase and lowercase improved recall, and presenting words simultaneously rather than successively removed the effect of presentation format. The findings suggest that when forcing participants to pay attention to printed words you can make them more memorable and thereby diminish or remove any disadvantage in the recall of printed words in comparison with pictures and spoken words.

Hallermann-Streiff syndrome with hypopituitarism contributing to growth failure.

A 35-month-old black boy with Hallermann-Streiff syndrome (HSS) was evaluated for anterior hypopituitarism when he presented with ketotic hypoglycemia, microgenitalia, and short stature. Endocrine evaluation showed a low T4 and TSH levels, suggesting hypothalamic hypothyroidism; this was confirmed by TRH stimulation. Metyrapone test confirmed ACTH deficiency as a contributing factor to the ketotic hypoglycemia. A superagonist GnRH test suggested hypothalamic GnRH deficiency. Growth hormone provocative testing conclusively demonstrated complete growth hormone deficiency. MRI investigation of the brain suggested hypopituitarism. Although facial findings were not completely classical of the HSS, we suggest these may be somewhat altered due to his racial back-ground. We recommend endocrine evaluation of HSS patients with manifestations suggesting hypopituitarism since treatment of this condition will improve the quality of life of these patients.

Replicable effects of primes on human behavior.

[Correction Notice: An Erratum for this article was reported online in Journal of Experimental Psychology: General on Oct 31 2016 (see record 2016-52334-001). ] The effect of primes (i.e., incidental cues) on human behavior has become controversial. Early studies reported counterintuitive findings, suggesting that primes can shape a wide range of human behaviors. Recently, several studies failed to replicate some earlier priming results, raising doubts about the reliability of those effects. We present a within-subjects procedure for priming behavior, in which participants decide whether to bet or pass on each trial of a gambling game. We report 6 replications (N = 988) showing that primes consistently affected gambling decisions when the decision was uncertain. Decisions were influenced by primes presented visibly, with a warning to ignore the primes (Experiments 1 through 3) and with subliminally presented masked primes (Experiment 4). Using a process dissociation procedure, we found evidence that primes influenced responses through both automatic and controlled processes (Experiments 5 and 6). Results provide evidence that primes can reliably affect behavior, under at least some conditions, without intention. The findings suggest that the psychological question of whether behavior priming effects are real should be separated from methodological issues affecting how easily particular experimental designs will replicate.

Hematological malignancies (HM) are highly amenable targets for immunotherapeutic intervention and may be effectively treated by antigen-specific T-cell based treatment. Recent studies demonstrate that physiologically occurring anti-cancer T-cell responses in certain HM entities target broadly presented non-mutated epitopes. HLA ligands are thus implied as prime targets for broadly applicable and antigen-specific off-the-shelf compounds. With the aim of assessing the presence of common targets shared among different HM which may enable addressing a larger patient collective we conducted a meta-analysis of 83 mass spectrometry-based HLA peptidome datasets (comprising 40,361 unique peptide identifications) across four major HM (19 AML, 16 CML, 35 CLL, and 13 MM/MCL samples) and investigated similarities and differences within the HLA presented antigenic landscape. We found the cancer HLA peptidome datasets to cluster specifically along entity and lineage lines, suggesting that the immunopeptidome directly reflects the differences in the underlying (tumor-)biology. In line with these findings, we only detected a small set of entity-spanning antigens, which were predominantly characterized by low presentation frequencies within the different patient cohorts. These findings suggest that design of T-cell immunotherapies for the treatment of HM should ideally be conducted in an entity-specific fashion. PMID:28159928

A 73-year-old woman was referred to our hospital due to epigastralgia and jaundice. The radiological findings showed a stone-like tumor in the extrahepatic bile duct. The patient was initially thought to have adenocarcinoma of the bile duct based on the findings of a pathological examination of the bile duct biopsy specimen and underwent pancreaticoduodenectomy; the final diagnosis of the lesion was so-called carcinosarcoma of the extrahepatic bile duct. She died of liver metastasis six months after the surgery. This case suggests that surgical resection is not adequate for achieving a radical cure, and the optimal treatment for extrahepatic bile duct carcinosarcoma should be established immediately.

In models of affect and cognition, it is held that positive affect broadens the scope of attention. Consistent with this claim, previous research has indeed suggested that positive affect is associated with impaired selective attention as evidenced by increased interference of spatially distant distractors. However, several recent findings cast doubt on the reliability of this observation. In the present study, we examined whether selective attention in a visual flanker task is influenced by positive mood induction. Across three experiments, positive affect consistently failed to exert any impact on selective attention. The implications of this null-finding for theoretical models of affect and cognition are discussed.

Theoretical Re-evaluations of Scaling Relations between SMBHs and Their Host Galaxies - 2. Importance of AGN Feedback Suggested by Stellar Age - Velocity Dispersion Relation

We present the galactic stellar age - velocity dispersion relation obtained from a semi-analytic model of galaxy formation. We divide galaxies into two populations: galaxies which have over-massive/under-massive black holes (BHs) against the best-fitting BH mass - velocity dispersion relation. We find that galaxies with larger velocity dispersion have older stellar ages. We also find that galaxies with over-massive BHs have older stellar ages. These results are consistent with observational results obtained from Martin-Navarro et al. (2016). We tested the model with weak AGN feedback and find that galaxies with larger velocity dispersion have a younger stellar age.

Prostate carcinoma mimicking a sphenoid wing meningioma.

2015-01-01

We report here on a rare case of a large, lateral sphenoid wing tumor with radiographic and intraoperative findings highly suggestive of meningioma, yet pathology was in fact consistent with metastatic prostate adenocarcinoma. An 81 year-old male presented with expressive dysphasia, right-sided weakness and headaches. Imaging revealed a heterogeneously-enhancing lesion based on the left lateral sphenoid wing. The presumed diagnosis was strongly in favor of meningioma, and the patient underwent complete resection of the dural-based lesion. Final pathology confirmed the unexpected finding of a metastatic prostate adenocarcinoma. Although he tolerated surgery well, the patient was subsequently referred for palliative therapy given findings of widespread systemic disease. Intracranial metastases may involve the dura, at times presenting with rare radiographic features highly suggestive for meningioma, as in our case here. This makes differentiation, at least based on imaging, a challenge. Elderly patients presenting with neurological deficits secondary to a newly-diagnosed, dural-based lesion should thus be considered for metastasis, prompting additional imaging studies (including body CT, MRI or PET) to rule out a primary lesion elsewhere. In some cases, this may affect the overall decision to proceed with surgical resection, or alternatively, to proceed directly to palliative therapy (the latter decision made in the context of widespread metastatic disease). We conclude that dural-based metastatic lesions may mimic meningiomas, warranting thorough pre-operative work-up to exclude the possibility of metastasis. In certain cases, identification of widespread disease might preclude surgery and favor palliation, instead. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Elevated Arc/Arg 3.1 protein expression in the basolateral amygdala following auditory trace-cued fear conditioning.

PubMed

2013-11-01

The underlying neuronal mechanisms of learning and memory have been heavily explored using associative learning paradigms. Two of the more commonly employed learning paradigms have been contextual and delay fear conditioning. In fear conditioning, a subject learns to associate a neutral stimulus (conditioned stimulus; CS), such as a tone or the context of the room, with a fear provoking stimulus (unconditioned stimulus; US), such as a mild footshock. Utilizing these two paradigms, various analyses have elegantly demonstrated that the amygdala plays a role in both fear-related associative learning paradigms. However, the amygdala's involvement in trace fear conditioning, a forebrain-dependent fear associative learning paradigm that has been suggested to tap into higher cognitive processes, has not been closely investigated. Furthermore, to our knowledge, the specific amygdala nuclei involved with trace fear conditioning has not been examined. The present study used Arc expression as an activity marker to determine the amygdala's involvement in trace fear associative learning and to further explore involvement of specific amygdalar nuclei. Arc is an immediate early gene that has been shown to be associated with neuronal activation and is believed to be necessary for neuronal plasticity. Findings from the present study demonstrated that trace-conditioned mice, compared to backward-conditioned (stimulation-control), delay-conditioned and naïve mice, exhibited elevated amygdalar Arc expression in the basolateral (BLA) but not the central (CeA) or the lateral amygdala (LA). These findings are consistent with previous reports demonstrating that the amygdala plays a critical role in trace conditioning. Furthermore, these findings parallel studies demonstrating hippocampal-BLA activation following contextual fear conditioning, suggesting that trace fear conditioning and contextual fear conditioning may involve similar amygdala nuclei. Together, findings from this study demonstrate similarities in the pathway for trace and contextual fear conditioning, and further suggest possible underlying mechanisms for acquisition and consolidation of these two types of fear-related learning.

Giant serous cystadenoma arising from an accessory ovary in a morbidly obese 11-year-old girl: a case report.

2008-01-18

Ectopic ovarian tissue is an unusual entity, especially if it is an isolated finding thought to be of embryological origin. An 11-year-old, morbidly obese female presented with left flank pain, nausea, and irregular menses. Various diagnostic procedures suggested a large ovarian cyst, and surgical resection was performed. Histologically, the resected mass was not of tubal origin as suspected, but a serous cystadenoma arising from ovarian tissue. The patient's two normal, eutopic ovaries were completely uninvolved and unaffected. A tumor arising from ectopic ovarian tissue of embryological origin seems the most likely explanation. We suggest refining the descriptive nomenclature so as to more precisely characterize the various presentations of ovarian ectopia.

Systematic reviews represent one of the most important tools for knowledge translation but users often struggle with understanding and interpreting their results. GRADE Summary-of-Findings tables have been developed to display results of systematic reviews in a concise and transparent manner. The current format of the Summary-of-Findings tables for presenting risks and quality of evidence improves understanding and assists users with finding key information from the systematic review. However, it has been suggested that additional methods to present risks and display results in the Summary-of-Findings tables are needed. We will conduct a non-inferiority parallel-armed randomized controlled trial to determine whether an alternative format to present risks and display Summary-of-Findings tables is not inferior compared to the current standard format. We will measure participant understanding, accessibility of the information, satisfaction, and preference for both formats. We will invite systematic review users to participate (that is clinicians, guideline developers, and researchers). The data collection process will be undertaken using the online 'Survey Monkey' system. For the primary outcome understanding, non-inferiority of the alternative format (Table A) to the current standard format (Table C) of Summary-of-Findings tables will be claimed if the upper limit of a 1-sided 95% confidence interval (for the difference of proportion of participants answering correctly a given question) excluded a difference in favor of the current format of more than 10%. This study represents an effort to provide systematic reviewers with additional options to display review results using Summary-of-Findings tables. In this way, review authors will have a variety of methods to present risks and more flexibility to choose the most appropriate table features to display (that is optional columns, risks expressions, complementary methods to display continuous outcomes, and so on).

From molecule to market: steroid hormones and financial risk-taking.

Coates, John M; Gurnell, Mark; Sarnyai, Zoltan

2010-01-27

Little is known about the role of the endocrine system in financial decision-making. Here, we survey research on steroid hormones and their cognitive effects, and examine potential links to trader performance in the financial markets. Preliminary findings suggest that cortisol codes for risk and testosterone for reward. A key finding of this endocrine research is the different cognitive effects of acute versus chronic exposure to hormones: acutely elevated steroids may optimize performance on a range of tasks; but chronically elevated steroids may promote irrational risk-reward choices. We present a hypothesis suggesting that the irrational exuberance and pessimism observed during market bubbles and crashes may be mediated by steroid hormones. If hormones can exaggerate market moves, then perhaps the age and sex composition among traders and asset managers may affect the level of instability witnessed in the financial markets.

Selective attention to signs of success: social dominance and early stage interpersonal perception.

PubMed

Maner, Jon K; DeWall, C Nathan; Gailliot, Matthew T

2008-04-01

Results from two experiments suggest that observers selectively attend to male, but not female, targets displaying signs of social dominance. Participants overestimated the frequency of dominant men in rapidly presented stimulus arrays (Study 1) and visually fixated on dominant men in an eyetracking experiment (Study 2). When viewing female targets, participants attended to signs of physical attractiveness rather than social dominance. Findings fit with evolutionary models of mating, which imply that dominance and physical attractiveness sometimes tend to be prioritized preferentially in judgments of men versus women, respectively. Findings suggest that sex differences in human mating are observed not only at the level of overt mating preferences and choices but also at early stages of interpersonal perception. This research demonstrates the utility of examining early-in-the-stream social cognition through the functionalist lens of adaptive thinking.

Final Syllable Lengthening (FSL) has been extensively examined in infant vocalizations in order to determine whether its basis is biological or learned. Findings suggest there may be a U-shaped developmental trajectory for FSL. The present study sought to verify this pattern and to determine whether vocal maturity and deafness influence FSL. Eight normally hearing infants, aged 0;3 to 1;0, and eight deaf infants, aged 0;8 to 4;0, were examined at three levels of prelinguistic vocal development: precanonical, canonical, and postcanonical. FSL was found at all three levels suggesting a biological basis for this phenomenon. Individual variability was, however, considerable. Reduction in the magnitude of FSL across the three sessions provided some support for a downward trend for FSL in infancy. Findings further indicated that auditory deprivation can significantly affect temporal aspects of infant speech production.

Public voices in pharmaceutical deliberations: negotiating "clinical benefit" in the FDA's Avastin Hearing.

Teston, Christa B; Graham, S Scott; Baldwinson, Raquel; Li, Andria; Swift, Jessamyn

2014-06-01

This article offers a hybrid rhetorical-qualitative discourse analysis of the FDA's 2011 Avastin Hearing, which considered the revocation of the breast cancer indication for the popular cancer drug Avastin. We explore the multiplicity of stakeholders, the questions that motivated deliberations, and the kinds of evidence presented during the hearing. Pairing our findings with contemporary scholarship in rhetorical stasis theory, Mol's (2002) construct of multiple ontologies, and Callon, Lascoumes, and Barthe's (2011) "hybrid forums," we demonstrate that the FDA's deliberative procedures elides various sources of evidence and the potential multiplicity of definitions for "clinical benefit." Our findings suggest that while the FDA invited multiple stakeholders to offer testimony, there are ways that the FDA might have more meaningfully incorporated public voices in the deliberative process. We conclude with suggestions for how a true hybrid forum might be deployed.

Pain, dissociation and subliminal self-representations.

PubMed

Bob, Petr

2008-03-01

According to recent evidence, neurophysiological processes coupled to pain are closely related to the mechanisms of consciousness. This evidence is in accordance with findings that changes in states of consciousness during hypnosis or traumatic dissociation strongly affect conscious perception and experience of pain, and markedly influence brain functions. Past research indicates that painful experience may induce dissociated state and information about the experience may be stored or processed unconsciously. Reported findings suggest common neurophysiological mechanisms of pain and dissociation and point to a hypothesis of dissociation as a defense mechanism against psychological and physical pain that substantially influences functions of consciousness. The hypothesis is also supported by findings that information can be represented in the mind/brain without the subject's awareness. The findings of unconsciously present information suggest possible binding between conscious contents and self-functions that constitute self-representational dimensions of consciousness. The self-representation means that certain inner states of own body are interpreted as mental and somatic identity, while other bodily signals, currently not accessible to the dominant interpreter's access are dissociated and may be defined as subliminal self-representations. In conclusion, the neurophysiological aspects of consciousness and its integrative role in the therapy of painful traumatic memories are discussed.

Longitudinal assessment of neuropsychological function in major depression.

PubMed

Douglas, Katie M; Porter, Richard J

2009-12-01

Neuropsychological impairment is a core component of major depression, yet its relationship to clinical state is unclear. The aims of the present review were to determine which neuropsychological domains and tasks were most sensitive to improvement in clinical state in major depression and to highlight the methodological issues in such research. Studies that included a baseline and at least one follow-up neuropsychological testing session in adults with major depression were identified using MEDLINE, Web of Science and ScienceDirect databases. Thirty studies were included in the review. Findings in younger adult populations suggested that improvement in mood was most strongly related to improved verbal memory and verbal fluency, while measures of executive functioning and attention tended to remain impaired across treatment. In late-life major depression, improved psychomotor speed was most closely related to treatment response, but there was much inconsistency between study findings, which may be due to methodological issues. In major depression, particular neuropsychological domains are more strongly related to clinical state than others. The findings from the present review suggest that the domains most sensitive to clinical state are verbal learning and memory, verbal fluency and psychomotor speed. In contrast, measures of attention and executive functioning perhaps represent more trait-like markers of major depression. With further methodologically sound research, the changes in neuropsychological function associated with treatment response may provide a means of evaluating different treatment strategies in major depression.

Decreased reward value of biological motion among individuals with autistic traits.

PubMed

Williams, Elin H; Cross, Emily S

2018-02-01

The Social Motivation Theory posits that a reduced sensitivity to the value of social stimuli, specifically faces, can account for social impairments in Autism Spectrum Disorders (ASD). Research has demonstrated that typically developing (TD) individuals preferentially orient towards another type of salient social stimulus, namely biological motion. Individuals with ASD, however, do not show this preference. While the reward value of faces to both TD and ASD individuals has been well-established, the extent to which individuals from these populations also find human motion to be rewarding remains poorly understood. The present study investigated the value assigned to biological motion by TD participants in an effort task, and further examined whether these values differed among individuals with more autistic traits. The results suggest that TD participants value natural human motion more than rigid, machine-like motion or non-human control motion, but this preference is attenuated among individuals reporting more autistic traits. This study provides the first evidence to suggest that individuals with more autistic traits find a broader conceptualisation of social stimuli less rewarding compared to individuals with fewer autistic traits. By quantifying the social reward value of human motion, the present findings contribute an important piece to our understanding of social motivation in individuals with and without social impairments.

Experimental support that ocular tremor in Parkinson's disease does not originate from head movement.

PubMed

Gitchel, George T; Wetzel, Paul A; Qutubuddin, Abu; Baron, Mark S

2014-07-01

Our recent report of ocular tremor in Parkinson's disease (PD) has raised considerable controversy as to the origin of the tremor. Using an infrared based eye tracker and a magnetic head tracker, we reported that ocular tremor was recordable in PD subjects with no apparent head tremor. However, other investigators suggest that the ocular tremor may represent either transmitted appendicular tremor or subclinical head tremor inducing the vestibulo-ocular reflex (VOR). The present study aimed to further investigate the origin of ocular tremor in PD. Eye movements were recorded in 8 PD subjects both head free, and with full head restraint by means of a head holding device and a dental impression bite plate. Head movements were recorded independently using both a high sensitivity tri-axial accelerometer and a magnetic tracking system, each synchronized to the eye tracker. Ocular tremor was observed in all 8 PD subjects and was not influenced by head free and head fixed conditions. Both magnetic tracking and accelerometer recordings supported that the ocular tremor was fully independent of head position. The present study findings support our initial findings that ocular tremor is a fundamental feature of PD unrelated to head movements. Although the utility of ocular tremor for diagnostic purposes requires validation, current findings in large cohorts of PD subjects suggest its potential as a reliable clinical biomarker.

A case of neurofibromatosis type II in a 19-year-old man is described with clinical and neuroimaging (MRI) findings. The diagnostic criteria of neurofibromatosis type I (NF1) and type II (NF2) and the optimal management options are still controversial. The authors suggest that this patient fulfills criteria of neurofibromatosis type II as well as partially neurofibromatosis type I. At present, without molecular analysis of DNA, this assumption can not be verified.

Many disease processes lead to chronic liver disease, however, progress has been made regarding common findings amongst these disease processes that may suggest a path forward for treatment. In particular, common alterations in the intestinal microflora of patients with different etiologies of liver disease may provide a clue as to the pathogenesis of these disorders as well a potential therapy. Data is still scant at this point, however, what is available suggests a promising opportunity for future studies to expand upon what has been demonstrated.

SemanticFind: Locating What You Want in a Patient Record, Not Just What You Ask For

PubMed Central

Prager, John M.; Liang, Jennifer J.; Devarakonda, Murthy V.

2017-01-01

We present a new model of patient record search, called SemanticFind, which goes beyond traditional textual and medical synonym matches by locating patient data that a clinician would want to see rather than just what they ask for. The new model is implemented by making extensive use of the UMLS semantic network, distributional semantics, and NLP, to match query terms along several dimensions in a patient record with the returned matches organized accordingly. The new approach finds all clinically related concepts without the user having to ask for them. An evaluation of the accuracy of SemanticFind shows that it found twice as many relevant matches compared to those found by literal (traditional) search alone, along with very high precision and recall. These results suggest potential uses for SemanticFind in clinical practice, retrospective chart reviews, and in automated extraction of quality metrics. PMID:28815139

High spatial validity is not sufficient to elicit voluntary shifts of attention.

PubMed

Pauszek, Joseph R; Gibson, Bradley S

2016-10-01

Previous research suggests that the use of valid symbolic cues is sufficient to elicit voluntary shifts of attention. The present study interpreted this previous research within a broader theoretical context which contends that observers will voluntarily use symbolic cues to orient their attention in space when the temporal costs of using the cues are perceived to be less than the temporal costs of searching without the aid of the cues. In this view, previous research has not addressed the sufficiency of valid symbolic cues, because the temporal cost of using the cues is usually incurred before the target display appears. To address this concern, 70%-valid spatial word cues were presented simultaneously with a search display. In addition, other research suggests that opposing cue-dependent and cue-independent spatial biases may operate in these studies and alter standard measures of orienting. After identifying and controlling these opposing spatial biases, the results of two experiments showed that the word cues did not elicit voluntary shifts of attention when the search task was relatively easy but did when the search task was relatively difficult. Moreover, the findings also showed that voluntary use of the word cues changed over the course of the experiment when the task was difficult, presumably because the temporal cost of searching without the cue lessened as the task got easier with practice. Altogether, the present findings suggested that the factors underlying voluntary control are multifaceted and contextual, and that spatial validity alone is not sufficient to elicit voluntary shifts of attention.

No Evidence for a Saccadic Range Effect for Visually Guided and Memory-Guided Saccades in Simple Saccade-Targeting Tasks

PubMed Central

Vitu, Françoise; Engbert, Ralf; Kliegl, Reinhold

2016-01-01

Saccades to single targets in peripheral vision are typically characterized by an undershoot bias. Putting this bias to a test, Kapoula [1] used a paradigm in which observers were presented with two different sets of target eccentricities that partially overlapped each other. Her data were suggestive of a saccadic range effect (SRE): There was a tendency for saccades to overshoot close targets and undershoot far targets in a block, suggesting that there was a response bias towards the center of eccentricities in a given block. Our Experiment 1 was a close replication of the original study by Kapoula [1]. In addition, we tested whether the SRE is sensitive to top-down requirements associated with the task, and we also varied the target presentation duration. In Experiments 1 and 2, we expected to replicate the SRE for a visual discrimination task. The simple visual saccade-targeting task in Experiment 3, entailing minimal top-down influence, was expected to elicit a weaker SRE. Voluntary saccades to remembered target locations in Experiment 3 were expected to elicit the strongest SRE. Contrary to these predictions, we did not observe a SRE in any of the tasks. Our findings complement the results reported by Gillen et al. [2] who failed to find the effect in a saccade-targeting task with a very brief target presentation. Together, these results suggest that unlike arm movements, saccadic eye movements are not biased towards making saccades of a constant, optimal amplitude for the task. PMID:27658191

A reappraisal of the uncanny valley: categorical perception or frequency-based sensitization?

PubMed Central

Burleigh, Tyler J.; Schoenherr, Jordan R.

The uncanny valley (UCV) hypothesis describes a non-linear relationship between perceived human-likeness and affective response. The “uncanny valley” refers to an intermediate level of human-likeness that is associated with strong negative affect. Recent studies have suggested that the uncanny valley might result from the categorical perception of human-like stimuli during identification. When presented with stimuli sharing human-like traits, participants attempt to segment the continuum in “human” and “non-human” categories. Due to the ambiguity of stimuli located at a category boundary, categorization difficulty gives rise to a strong, negative affective response. Importantly, researchers who have studied the UCV in terms of categorical perception have focused on categorization responses rather than affective ratings. In the present study, we examined whether the negative affect associated with the UCV might be explained in terms of an individual's degree of exposure to stimuli. In two experiments, we tested a frequency-based model against a categorical perception model using a category-learning paradigm. We manipulated the frequency of exemplars that were presented to participants from two categories during a training phase. We then examined categorization and affective responses functions, as well as the relationship between categorization and affective responses. Supporting previous findings, categorization responses suggested that participants acquired novel category structures that reflected a category boundary. These category structures appeared to influence affective ratings of eeriness. Crucially, participants' ratings of eeriness were additionally affected by exemplar frequency. Taken together, these findings suggest that the UCV is determined by both categorical properties as well as the frequency of individual exemplars retained in memory. PMID:25653623

Chylous ascites associated with intestinal obstruction from volvulus due to Petersen's hernia: report of a case.

Chylous ascites is an uncommon finding which is usually associated with recent abdominal/oncologic or retroperitoneal surgery. It is not usually seen in cases of acute obstruction. A patient who had previously undergone a laparoscopy-assisted distal gastrectomy with Roux-en-Y reconstruction for early gastric cancer presented with acute abdominal pain and epigastric fullness. Computed tomography suggested small bowel obstruction due to volvulus. We were able to reduce the volvulus and close a Petersen's hernia without resecting the bowel; a large amount of chylous ascites was an incidental finding. We present a case of chylous ascites occurring in a setting of small bowel obstruction due to Petersen's hernia, 3 years after successful distal gastrectomy for early gastric cancer, with no evidence of tumor recurrence.

Acute Disseminated Encephalomyelitis: A Gray Distinction.

PubMed

Abu Libdeh, Amal; Goodkin, Howard P; Ramirez-Montealegre, Denia; Brenton, J Nicholas

2017-03-01

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated, inflammatory acquired demyelinating syndrome predominantly affecting the white matter of the central nervous system. We describe a three-year-old boy whose clinical presentation was suspicious for ADEM but whose initial imaging abnormalities were confined to the deep gray matter (without evidence of white matter involvement). His clinical course was fluctuating and repeat imaging one week after presentation demonstrated interval development of characteristic white matter lesions. Treatment with adjunctive intravenous immunoglobulin and high-dose corticosteroids resulted in significant clinical improvement. Isolated deep gray matter involvement can precede the appearance of white matter abnormalities of ADEM, suggesting that repeat imaging is indicated in individuals whose findings are clinically suspicious for ADEM but who lack characteristic imaging findings.

2009-01-01

We present the case of a young adult who developed acute encephalopathy with severe status epilepticus and rapid deterioration to vegetative state and death within 6 weeks. Although the clinical picture, MRI and EEG findings were atypical, the hypothesis of subacute sclerosing panencephalitis (SSPE) was suggested by markedly increased intrathecal IgG synthesis in the cerebrospinal fluid, and diagnosis was confirmed by the presence of high antimeasles antibodies in cerebrospinal fluid and brain biopsy findings. Acute SSPE is an exceptionally rare and little-known form of SSPE with protean symptomatology, and this case is to our knowledge the first observation of SSPE presenting with status epilepticus in adults. Our case reinforces the need to include, even in developed countries, SSPE as a diagnostic possibility in unexplained acute encephalopathies. PMID:21686559

Influences of emotion on context memory while viewing film clips.

PubMed

Anderson, Lisa; Shimamura, Arthur P

2005-01-01

Participants listened to words while viewing film clips (audio off). Film clips were classified as neutral, positively valenced, negatively valenced, and arousing. Memory was assessed in three ways: recall of film content, recall of words, and context recognition. In the context recognition test, participants were presented a word and determined which film clip was showing when the word was originally presented. In two experiments, context memory performance was disrupted when words were presented during negatively valenced film clips, whereas it was enhanced when words were presented during arousing film clips. Free recall of words presented during the negatively valenced films was also disrupted. These findings suggest multiple influences of emotion on memory performance.

Selective attention modulates visual and haptic repetition priming: effects in aging and Alzheimer's disease.

Ballesteros, Soledad; Reales, José M; Mayas, Julia; Heller, Morton A

2008-08-01

In two experiments, we examined the effect of selective attention at encoding on repetition priming in normal aging and Alzheimer's disease (AD) patients for objects presented visually (experiment 1) or haptically (experiment 2). We used a repetition priming paradigm combined with a selective attention procedure at encoding. Reliable priming was found for both young adults and healthy older participants for visually presented pictures (experiment 1) as well as for haptically presented objects (experiment 2). However, this was only found for attended and not for unattended stimuli. The results suggest that independently of the perceptual modality, repetition priming requires attention at encoding and that perceptual facilitation is maintained in normal aging. However, AD patients did not show priming for attended stimuli, or for unattended visual or haptic objects. These findings suggest an early deficit of selective attention in AD. Results are discussed from a cognitive neuroscience approach.

Location of CDC in the matter of network on Supply Chain is becoming on the high concern these days. Present status of methods on CDC has been mainly based on the calculation manually by the spread sheet to achieve the goal of minimum logistics cost. This study is focused on the development of new processing algorithm to overcome the limit of present methods, and examination of the propriety of this algorithm by case study. The algorithm suggested by this study is based on the principle of optimization on the directive GRAPH of SCM model and suggest the algorithm utilizing the traditionally introduced MST, shortest paths finding methods, etc. By the aftermath of this study, it helps to assess suitability of the present on-going SCM network and could be the criterion on the decision-making process for the optimal SCM network building-up for the demand prospect in the future.

Three UK bred Border collie puppies were presented for investigation of pyrexia and severe lameness with associated joint swelling. Investigations revealed neutropenia, radiographic findings suggesting metaphyseal osteopathy, and polyarthritis and all dogs were subsequently confirmed with trapped neutrophil syndrome. Clinical improvement was seen after treatment with prednisolone and antibiotics and the dogs all survived to adulthood with a good short- to medium-term outcome. Trapped neutrophil syndrome is an important differential diagnosis for young Border collie dogs in the UK presenting with pyrexia, neutropenia and musculoskeletal signs. © 2013 British Small Animal Veterinary Association.

An analysis of online messages about probiotics

PubMed Central

2013-01-01

Internet websites are a resource for patients seeking information about probiotics. We examined a sample of 71 websites presenting probiotic information. We found that descriptions of benefits far outnumbered descriptions of risks and commercial websites presented significantly fewer risks than noncommercial websites. The bias towards the presentation of therapeutic benefits in online content suggests that patients are likely interested in using probiotics and may have unrealistic expectations for therapeutic benefit. Gastroenterologists may find it useful to initiate conversations about probiotics within the context of a comprehensive health management plan and should seek to establish realistic therapeutic expectations with their patients.

Purpose - The purpose of this paper is to reflect on the findings of this special issue and discusses the future challenges for policy, research and society. The findings suggest that challenges emerge as a result of legitimacy deficits of both consensus and contestatory modes of public involvement in health priority setting. Design/methodology/approach - The paper draws on the discussions and findings presented in this special issue. It seeks to bring the country experiences and case studies together to draw conclusions for policy, research and society. Findings - At least two recurring themes emerge. An underlying theme is the importance, but also the challenge, of establishing legitimacy in health priority setting. The country experiences suggest that we understand very little about the conditions under which representative, or authentic, participation generates legitimacy and under which it will be regarded as insufficient. A second observation is that public participation takes a variety of forms that depend on the opportunity structures in a given national context. Given this variety the conceptualization of public participation needs to be expanded to account for the many forms of public participation. Originality/value - The paper concludes that the challenges of public involvement are closely linked to the question of how legitimate processes and decisions can be generated in priority setting. This suggests that future research must focus more narrowly on conditions under which legitimacy are generated in order to expand the understanding of public involvement in health prioritization.

Transfer of memory retrieval cues in rats.

PubMed

Briggs, James F; Fitz, Kelly I; Riccio, David C

2007-06-01

Two experiments using rats were conducted to determine whether the retrieval of a memory could be brought under the control of new contextual cues that had not been present at the time of training. In Experiment 1, rats were trained in one context and then exposed to different contextual cues immediately, 60 min, or 120 min after training. When tested in the shifted context, rats that had been exposed shortly after training treated the shifted context as if it were the original context. The control that the previously neutral context had over retrieval disappeared with longer posttraining delays, suggesting the importance of an active memory representation during exposure. Experiment 2 replicated the basic finding and demonstrated that the transfer of retrieval cues was specific to the contextual cues present during exposure. These findings with rats are consistent with findings from infant research (see, e.g., Boller & Rovee-Collier, 1992) that have shown that a neutral context can come to serve as a retrieval cue for an episode experienced elsewhere.

We also find good agreement between the mass map and the distribution of massive galaxy clusters identified using a red-sequence cluster finder. Potential candidates for superclusters and voids are identified using these maps. We measure the cross-correlation between the mass map and a magnitude-limited foreground galaxy sample and find a detection at the 6.8σ level with 20 arc min smoothing.more » These measurements are consistent with simulated galaxy catalogs based on N-body simulations from a cold dark matter model with a cosmological constant.

Delayed visual attention caused by high myopic refractive error.

Winges, Kimberly M; Zarpellon, Ursula; Hou, Chuan; Good, William V

2005-06-01

Delayed visual maturation (DVM) is usually a retrospective diagnosis given to infants who are born with no or poor visually-directed behavior, despite normal acuity on objective testing, but who recover months later. This condition can be organized into several types based on associated neurodevelopmental or ocular findings, but the etiology of DVM is probably complex and involves multiple possible origins. Here we report two infants who presented with delayed visual maturation (attention). They were visually unresponsive at birth but were later found to have high myopic errors. Patient 1 had -4 D right eye, -5 D left eye. Patient 2 had -9 D o.u. Upon spectacle correction at 5 and 4 months, respectively, both infants immediately displayed visually-directed behavior, suggesting that a high refractive error was the cause of inattention in these patients. These findings could add to knowledge surrounding DVM and the diagnosis of apparently blind infants. Findings presented here also indicate the importance of prompt refractive error measurement in such cases.

Phase I Design for Completely or Partially Ordered Treatment Schedules

Wages, Nolan A.; O’Quigley, John; Conaway, Mark R.

2013-01-01

The majority of methods for the design of Phase I trials in oncology are based upon a single course of therapy, yet in actual practice it may be the case that there is more than one treatment schedule for any given dose. Therefore, the probability of observing a dose-limiting toxicity (DLT) may depend upon both the total amount of the dose given, as well as the frequency with which it is administered. The objective of the study then becomes to find an acceptable combination of both dose and schedule. Past literature on designing these trials has entailed the assumption that toxicity increases monotonically with both dose and schedule. In this article, we relax this assumption for schedules and present a dose-schedule finding design that can be generalized to situations in which we know the ordering between all schedules and those in which we do not. We present simulation results that compare our method to other suggested dose-schedule finding methodology. PMID:24114957

Predicting Heavy Alcohol Use in College Students: Interactions Among Socialization of Coping, Alcohol Use Onset, and Physiological Reactivity.

PubMed

Stanger, Sarah; Abaied, Jamie; Wagner, Caitlin

2016-05-01

Early age at onset of alcohol use is a risk factor for later heavy alcohol use, but some individuals are buffered from this risk. To better understand this process, this study investigated the interactive contributions of parental coping suggestions, skin conductance level reactivity (SCLR), and age at onset of alcohol use on heavy alcohol use in college students. College students (N = 146, 77% female) reported their age at onset of alcohol use, frequency of recent heavy alcohol use, and their parents' coping suggestions; SCLR was monitored as participants completed a laboratory challenge task. In addition, students' parents (N = 73, 77% mothers) reported on their coping suggestions. Results indicated that in the presence of physiological risk only (blunted SCLR, late age at onset of alcohol use), higher frequencies of engagement and disengagement parental coping suggestions were protective against heavy alcohol use in college students. However, if both risk factors were present (blunted SCLR, early age at onset of alcohol use), more engagement suggestions predicted more heavy alcohol use among college students. These findings extend previous findings on the impact of parenting on heavy alcohol use among college students and provide novel evidence for the moderating role of sympathetic stress reactivity.

Multiple context mere exposure: Examining the limits of liking.

PubMed

de Zilva, Daniel; Newell, Ben R; Mitchell, Chris J

2016-01-01

Recent evidence suggests that increased liking of exposed stimuli-a phenomenon known as the mere exposure effect-is dependent on experiencing the stimuli in the same context at exposure and test. Three experiments extended this work by examining the effect of presenting target stimuli in single and multiple exposure contexts. Target face stimuli were repeatedly paired with nonsense words, which took the role of contexts, across exposure. On test, the mere exposure effect was found only when the target face stimuli were presented with nonsense word cues (contexts) with which they had been repeatedly paired. The mere exposure effect was eliminated when exposure to target face stimuli with the nonsense word cues (contexts) was minimal, despite the overall number of exposures to the target face being equated across single- and multiple-context exposure conditions. The results suggest that familiarity of the relationship between stimuli and their context, not simply familiarity of the stimuli themselves, leads to liking. The finding supports a broader framework, which suggests that liking is partly a function of the consistency between past and present experiences with a target stimulus.

Feature binding and attention in working memory: a resolution of previous contradictory findings.

Allen, Richard J; Hitch, Graham J; Mate, Judit; Baddeley, Alan D

2012-01-01

We aimed to resolve an apparent contradiction between previous experiments from different laboratories, using dual-task methodology to compare effects of a concurrent executive load on immediate recognition memory for colours or shapes of items or their colour-shape combinations. Results of two experiments confirmed previous evidence that an irrelevant attentional load interferes equally with memory for features and memory for feature bindings. Detailed analyses suggested that previous contradictory evidence arose from limitations in the way recognition memory was measured. The present findings are inconsistent with an earlier suggestion that feature binding takes place within a multimodal episodic buffer Baddeley, ( 2000 ) and support a subsequent account in which binding takes place automatically prior to information entering the episodic buffer Baddeley, Allen, & Hitch, ( 2011 ). Methodologically, the results suggest that different measures of recognition memory performance (A', d', corrected recognition) give a converging picture of main effects, but are less consistent in detecting interactions. We suggest that this limitation on the reliability of measuring recognition should be taken into account in future research so as to avoid problems of replication that turn out to be more apparent than real.

The relationship between suggestibility and anxiety among suspects detained at police stations.

Gudjonsson, G H; Rutter, S C; Clare, I C

1995-07-01

The present study investigated the relationship between anxiety, as measured by the State-Trait Inventory (Spielberger, 1983) and interrogative suggestibility, as measured by the Gudjonsson Suggestibility Scale (GSS 2, Gudjonsson, 1987). One hundred and sixty-one suspects detained at two English police stations for questioning were assessed prior to being interviewed by the police. Unexpectedly, trait anxiety correlated more consistently with suggestibility than did state anxiety. The correlations were consistently higher among the Caucasian than the Afro-Caribbean subjects and the Afro-Caribbean subjects were significantly more suggestible than the Caucasian subjects even after their GSS 2 memory and IQ scores had been controlled for. The main practical implications of the findings are that interrogative suggestibility cannot be easily evaluated from the person's self-reported anxiety and the situation in which people are assessed may influence the relationship between these psychological variables.

It's not just lunch: extra-pair commensality can trigger sexual jealousy.

Do people believe that sharing food might involve sharing more than just food? To investigate this, participants were asked to rate how jealous they (Study 1)--or their best friend (Study 2)--would be if their current romantic partner were contacted by an ex-romantic partner and subsequently engaged in an array of food- and drink-based activities. We consistently find--across both men and women--that meals elicit more jealousy than face-to-face interactions that do not involve eating, such as having coffee. These findings suggest that people generally presume that sharing a meal enhances cooperation. In the context of romantic pairs, we find that participants are attuned to relationship risks that extra-pair commensality can present. For romantic partners left out of a meal, we find a common view that lunch, for example, is not "just lunch."

1983-12-01

In an attempt to extend the findings of previous research and to investigate the hypothesis of a link between exhibitionism and pedophilia, samples of Australian offenders undergoing presentence psychiatric assessment were compared on a number of variables. The data suggested that the exhibitionists and pedophiles in the sample represented different populations: the exhibitionists were younger, tended to come from more stable and harmonious families, and had superior school and work records. The common assumption of disinhibition as a feature of exhibitionism was questioned on the basis of the finding that almost no exhibitionists were intoxicated at the time of their offense.

Information wa obtained from a 59-question instrument aimed at exploring: Sociodemographic aspects, alcohol ingestion-abstention patterns; interpersonal, family and labor relationships, autodiagnosis, and evaluation of the treatment program. During the 3-week inpatient treatment, a psychosocial treatment was administered to all subjects. Owing to the substantial changes patients evidenced in the above mentioned areas, findings suggest that the objectives were fulfilled satisfactorily enough.

An adult male reticulated giraffe (Giraffa camelopardalis reticulata) was presented for postmortem examination. During radiologic examination of the hindlimbs, osseous cyst-like lesions were detected in both medial femoral condyles. These lesions were subsequently examined macroscopically and histologically. The gross appearance suggested a diagnosis of bilateral osteochondrosis that was confirmed with histopathologic examination. This finding has not previously been reported in giraffes. Macroscopic visualization of the major limb joints, including the femorotibial joints, is therefore encouraged in future postmortem examinations of giraffes (Giraffa camelopardalis), and further assessment of clinical significance is required.

Classroom management of situated group learning: A research study of two teaching strategies

Smeh, Kathy; Fawns, Rod

2000-06-01

Although peer-based work is encouraged by theories in developmental psychology and although classroom interventions suggest it is effective, there are grounds for recognising that young pupils find collaborative learning hard to sustain. Discontinuities in collaborative skill during development have been suggested as one interpretation. Theory and research have neglected situational continuities that the teacher may provide in management of formal and informal collaborations. This experimental study, with the collaboration of the science faculty in one urban secondary college, investigated the effect of two role attribution strategies on communication in peer groups of different gender composition in three parallel Year 8 science classes. The group were set a problem that required them to design an experiment to compare the thermal insulating properties of two different materials. This presents the data collected and key findings, and reviews the findings from previous parallel studies that have employed the same research design in different school settings. The results confirm the effectiveness of social role attribution strategies in teacher management of communication in peer-based work.

Childhood callous-unemotional traits moderate the relation between parenting distress and conduct problems over time.

2014-01-01

The present short-term longitudinal study examines the bidirectional effects among paternal-reported and maternal-reported involvement, distress and conduct-problems (CP) in children ages 7–12 years with callous-unemotional (CU) traits as a potential moderator. Latent profile analysis revealed four groups: high, moderate, decreasing, and low on CU traits. Findings suggested that children high on CU traits were at higher risk to exhibit CP and were more likely to experience low parental-involvement and high parental-distress compared to children with low, decreasing, and moderate CU traits. Findings from the cross-lagged structural equation model suggested that high levels of CP predicted increases in parenting distress, and this was shown for youth with high levels of CU traits. In turn, parental-reported distress predicted increases in CP for children in the low and decreasing CU groups. A negative bidirectional association between maternal-involvement and CP was also identified. Findings extend cross-sectional research showing parents become distressed by CP behaviors, particularly when accompanied by high CU traits.

[Depressive realism: happiness or objectivity].

PubMed

Birinci, Fatih; Dirik, Gülay

2010-01-01

Realism is described as objective evaluations and judgments about the world; however, some research indicates that judgments made by "normal" people include a self-favored, positive bias in the perception of reality. Additionally, some studies report that compared to normal people, such cognitive distortions are less likely among depressive people. These findings gave rise to the depressive realism hypothesis. While results of several studies verify the notion that depressive people evaluate reality more objectively, other studies fail to support this hypothesis. Several causes for these inconsistent findings have been proposed, which can be characterized under 3 headings. One proposed explanation suggests that what is accepted as "realistic" in these studies is not quite objective and is in fact ambiguous. According to another perspective, the term "depressive" used in these studies is inconsistent with the criteria of scientific diagnostic methods. Another suggests that the research results can only be obtained under the specific experimental conditions. General negativity and limited processing are popular approaches used for explaining the depressive realism hypothesis. Nowadays, the debate over this hypothesis continues. The present review focuses on frequently cited research related to depressive realism and discusses the findings.

Why do employees have better family lives when they are highly engaged at work?

Past research on the effects of work engagement on the family has demonstrated contrasting effects, with some suggesting that work engagement is beneficial for family life whereas others suggesting that it may be detrimental. In this research, using a sample of 125 employees who responded to daily surveys both at work and at home for 2 consecutive weeks, the authors present a multilevel examination of the relationships of work engagement to family outcomes aimed at elucidating such work-family effects. Their findings revealed that employees' daily work engagement experiences related positively, within individuals, to work-family interpersonal capitalization, which in turn, related positively to daily family satisfaction and to daily work-family balance. The findings also indicate that both the relationship between daily work engagement and work-family interpersonal capitalization and the indirect effects of daily work engagement on the family outcomes were stronger for employees with higher intrinsic motivation than for those with lower intrinsic motivation. The authors discuss theoretical and practical implications of the findings and offer directions for future research. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

2017-01-01

There has been a rapid growth of studies focused on selection and socialization processes of peer groups, mostly due to the development of stochastic actor-based models to analyze longitudinal social network data. One of the core assumptions of these models is that individuals have an accurate knowledge of the dyadic relationships within their network (i.e., who is and is not connected to whom). Recent cross-sectional findings suggest that elementary school children are very inaccurate in perceiving their classmates’ dyadic relationships. These findings question the validity of stochastic actor-based models to study the developmental dynamics of children and carry implications for future research as well as for the interpretation of past findings. The goal of the present study was thus to further explore the adequacy of the accuracy assumption, analysing data from three longitudinal samples of different age groups (elementary school children and adolescents). Our results support the validity of stochastic actor-based models to study the network of adolescents and suggest that the violation of the accuracy assumption for elementary school children is not as severe as previously thought.

Does Encouragement Matter in Improving Gender Imbalances in Technical Fields? Evidence from a Randomized Controlled Trial

Unkovic, Cait; Sen, Maya; Quinn, Kevin M.

2016-01-01

Does encouragement help address gender imbalances in technical fields? We present the results of one of the first and largest randomized controlled trials on the topic. Using an applied statistics conference in the social sciences as our context, we randomly assigned half of a pool of 3,945 graduate students to receive two personalized emails encouraging them to apply (n = 1,976) and the other half to receive nothing (n = 1,969). We find a robust, positive effect associated with this simple intervention and suggestive evidence that women responded more strongly than men. However, we find that women’s conference acceptance rates are higher within the control group than in the treated group. This is not the case for men. The reason appears to be that female applicants in the treated group solicited supporting letters at lower rates. Our findings therefore suggest that “low dose” interventions may promote diversity in STEM fields but may also have the potential to expose underlying disparities when used alone or in a non-targeted way.

Intelligence related upper alpha desynchronization in a semantic memory task.

Recent evidence shows that event-related (upper) alpha desynchronization (ERD) is related to cognitive performance. Several studies observed a positive, some a negative relationship. The latter finding, interpreted in terms of the neural efficiency hypothesis, suggests that good performance is associated with a more 'efficient', smaller extent of cortical activation. Other studies found that ERD increases with semantic processing demands and that this increase is larger for good performers. Studies supporting the neural efficiency hypothesis used tasks that do not specifically require semantic processing. Thus, we assume that the lack of semantic processing demands may at least in part be responsible for the reduced ERD. In the present study we measured ERD during a difficult verbal-semantic task. The findings demonstrate that during semantic processing, more intelligent (as compared to less intelligent) subjects exhibited a significantly larger upper alpha ERD over the left hemisphere. We conclude that more intelligent subjects exhibit a more extensive activation in a semantic processing system and suggest that divergent findings regarding the neural efficiency hypotheses are due to task specific differences in semantic processing demands.

Evidence of Reduced Global Processing in Autism Spectrum Disorder.

PubMed

Booth, Rhonda D L; Happé, Francesca G E

2018-04-01

Frith's original notion of 'weak central coherence' suggested that increased local processing in autism spectrum disorder (ASD) resulted from reduced global processing. More recent accounts have emphasised superior local perception and suggested intact global integration. However, tasks often place local and global processing in direct trade-off, making it difficult to determine whether group differences reflect reduced global processing, increased local processing, or both. We present two measures of global integration in which poor performance could not reflect increased local processing. ASD participants were slower to identify fragmented figures and less sensitive to global geometric impossibility than IQ-matched controls. These findings suggest that reduced global integration comprises one important facet of weak central coherence in ASD.

Ethnic identity and mentoring among Latinas in professional roles.

Gonzáles-Figueroa, Evelyn; Young, Angela M

2005-08-01

This study examined ethnic identity and mentoring (a known strategy to promote career success and advancement) in a sample of 103 Latina women with professional roles in the areas of business, academia, policy, and politics. Other variables examined included traditional gender roles and perceptions of professional success. Findings indicated that the women's ethnic identity was consistent with a bicultural profile; some received mentoring and, if given a choice, would prefer to be mentored by someone of similar ethnicity. This finding is critical and can allow researchers, service providers, and policy developers to apply culturally responsive strategies in communities and in organizations. Other hypotheses were not supported. A discussion of the findings, implications, and suggestions for future research are presented. (c) 2005 APA

Whorfian effects on colour memory are not reliable.

PubMed

Wright, Oliver; Davies, Ian R L; Franklin, Anna

2015-01-01

The Whorfian hypothesis suggests that differences between languages cause differences in cognitive processes. Support for this idea comes from studies that find that patterns of colour memory errors made by speakers of different languages align with differences in colour lexicons. The current study provides a large-scale investigation of the relationship between colour language and colour memory, adopting a cross-linguistic and developmental approach. Colour memory on a delayed matching-to-sample (XAB) task was investigated in 2 language groups with differing colour lexicons, for 3 developmental stages and 2 regions of colour space. Analyses used a Bayesian technique to provide simultaneous assessment of two competing hypotheses (H1-Whorfian effect present, H0-Whorfian effect absent). Results of the analyses consistently favoured H0. The findings suggest that Whorfian effects on colour memory are not reliable and that the importance of such effects should not be overestimated.

Shared conceptualizations and divergent experiences of counseling among African American and white older adults.

PubMed

Joo, Jin Hui; Wittink, Marsha; Dahlberg, Britt

2011-08-01

Research findings suggest that older adults prefer counseling for depression treatment; however, few older adults use counseling services. In this article we present the results of our analysis of semistructured interviews with 102 older adults to explore conceptualizations of counseling and impediments to use among African American and White older adults. We found that older adults believe counseling is beneficial; however, use was hindered in multiple ways. Older adults were skeptical about establishing a caring relationship with a professional. African American older adults did not mention social relationships to facilitate depression care, whereas White older adults described using personal relationships to navigate counseling services. African American older men were least familiar with counseling. Our findings suggest that African American and White older adults share a strong cultural model of counseling as beneficial; however, significant impediments exist and affect older adults differentially based on ethnicity.

Chiral fermions in asymptotically safe quantum gravity

Meibohm, J.; Pawlowski, J. M.

2016-05-01

We study the consistency of dynamical fermionic matter with the asymptotic safety scenario of quantum gravity using the functional renormalisation group. Since this scenario suggests strongly coupled quantum gravity in the UV, one expects gravity-induced fermion self-interactions at energies of the Planck scale. These could lead to chiral symmetry breaking at very high energies and thus to large fermion masses in the IR. The present analysis which is based on the previous works (Christiansen et al., Phys Rev D 92:121501, 2015; Meibohm et al., Phys Rev D 93:084035, 2016), concludes that gravity-induced chiral symmetry breaking at the Planck scale is avoided for a general class of NJL-type models. We find strong evidence that this feature is independent of the number of fermion fields. This finding suggests that the phase diagram for these models is topologically stable under the influence of gravitational interactions.

Complete pancreatic heterotopia of gallbladder with hypertrophic duct simulating an adenomyoma

Pilloni, Luca; Cois, Alessandro; Uccheddu, Alessandro; Ambu, Rossano; Coni, Pierpaolo; Faa, Gavino

2006-01-01

The gallbladder is an unusual location of pancreatic heterotopia, defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the main body of the gland. A 28-year-old man presented with anorexia, nausea and pain in the right upper abdomen. On physical examination, the abdomen was tender to palpation and Murphy sign was positive. The patient underwent a cholecystecomy. This case, in our opinion, is very interesting since it permits to consider a controversial issue in the pathology of the gallbladder. The histological appearance of ductal structure in pancreatic heterotopia resembles the histological picture of both Aschoff-Rokitansky (AR) sinuses and adenomyomas. This finding suggests that these lesions are linked by a common histogenetic origin. We suggest that the finding of an adenomyoma in the gallbladder should prompt an extensive sampling of the organ in order to verify the coexistence of pancreatic rests. PMID:16586554

From molecule to market: steroid hormones and financial risk-taking

Coates, John M.; Gurnell, Mark; Sarnyai, Zoltan

2010-01-01

Little is known about the role of the endocrine system in financial decision-making. Here, we survey research on steroid hormones and their cognitive effects, and examine potential links to trader performance in the financial markets. Preliminary findings suggest that cortisol codes for risk and testosterone for reward. A key finding of this endocrine research is the different cognitive effects of acute versus chronic exposure to hormones: acutely elevated steroids may optimize performance on a range of tasks; but chronically elevated steroids may promote irrational risk-reward choices. We present a hypothesis suggesting that the irrational exuberance and pessimism observed during market bubbles and crashes may be mediated by steroid hormones. If hormones can exaggerate market moves, then perhaps the age and sex composition among traders and asset managers may affect the level of instability witnessed in the financial markets.

Survival Processing Enhances Visual Search Efficiency.

PubMed

Cho, Kit W

2018-05-01

Words rated for their survival relevance are remembered better than when rated using other well-known memory mnemonics. This finding, which is known as the survival advantage effect and has been replicated in many studies, suggests that our memory systems are molded by natural selection pressures. In two experiments, the present study used a visual search task to examine whether there is likewise a survival advantage for our visual systems. Participants rated words for their survival relevance or for their pleasantness before locating that object's picture in a search array with 8 or 16 objects. Although there was no difference in search times among the two rating scenarios when set size was 8, survival processing reduced visual search times when set size was 16. These findings reflect a search efficiency effect and suggest that similar to our memory systems, our visual systems are also tuned toward self-preservation.

The influence of music-elicited emotions and relative pitch on absolute pitch memory for familiar melodies.

Jakubowski, Kelly; Müllensiefen, Daniel

2013-01-01

Levitin's findings that nonmusicians could produce from memory the absolute pitches of self-selected pop songs have been widely cited in the music psychology literature. These findings suggest that latent absolute pitch (AP) memory may be a more widespread trait within the population than traditional AP labelling ability. However, it has been left unclear what factors may facilitate absolute pitch retention for familiar pieces of music. The aim of the present paper was to investigate factors that may contribute to latent AP memory using Levitin's sung production paradigm for AP memory and comparing results to the outcomes of a pitch labelling task, a relative pitch memory test, measures of music-induced emotions, and various measures of participants' musical backgrounds. Our results suggest that relative pitch memory and the quality and degree of music-elicited emotions impact on latent AP memory.

Parallel functional category deficits in clauses and nominal phrases: The case of English agrammatism

PubMed Central

Wang, Honglei; Yoshida, Masaya; Thompson, Cynthia K.

2015-01-01

Individuals with agrammatic aphasia exhibit restricted patterns of impairment of functional morphemes, however, syntactic characterization of the impairment is controversial. Previous studies have focused on functional morphology in clauses only. This study extends the empirical domain by testing functional morphemes in English nominal phrases in aphasia and comparing patients’ impairment to their impairment of functional morphemes in English clauses. In the linguistics literature, it is assumed that clauses and nominal phrases are structurally parallel but exhibit inflectional differences. The results of the present study indicated that aphasic speakers evinced similar impairment patterns in clauses and nominal phrases. These findings are consistent with the Distributed Morphology Hypothesis (DMH), suggesting that the source of functional morphology deficits among agrammatics relates to difficulty implementing rules that convert inflectional features into morphemes. Our findings, however, are inconsistent with the Tree Pruning Hypothesis (TPH), which suggests that patients have difficulty building complex hierarchical structures. PMID:26379370

Perspective on the prospects of a carrier multiplication nanocrystal solar cell.

PubMed

Nair, Gautham; Chang, Liang-Yi; Geyer, Scott M; Bawendi, Moungi G

2011-05-11

This article presents a perspective on the experimental and theoretical work to date on the efficiency of carrier multiplication (CM) in colloidal semiconductor nanocrystals (NCs). Early reports on CM in NCs suggested large CM efficiency enhancements. However, recent experiments have shown that CM in nanocrystalline samples is not significantly stronger, and often is weaker, than in the parent bulk when compared on an absolute photon energy basis. This finding is supported by theoretical consideration of the CM process and the competing intraband relaxation. We discuss the experimental artifacts that may have led to the apparently strong CM estimated in early reports. The finding of bulklike CM in NCs suggests that the main promise of quantum confinement is to boost the photovoltage at which carriers can be extracted. With this in mind, we discuss research directions that may result in effective use of CM in a solar cell.

Focal extra-axial hemorrahagic mass with subdural hemorrhage secondare to extramedullary hematopoiesis in idiopathic myelodysplastic sindrome.

2007-03-01

Idiopathic myelodysplastic syndrome is a disease characterized by a clonal stem cell disorder in which megacaryocitic and granulocytic lineages are mainly involved; extramedullary myeloid metaplasia is due to abnormal location of myeloid tissue in other organs than bone marrow. Rarely the central nervous system is involved. When it happens, it is typical to find masses around the brain and pachymeningeal thickening, but it is very rare to find it associated with subdural haemorrhage, as in the case we describe in the present article. Considering our case and the literature we can suggest that radiological images associated with the clinical history of the patient suggestive for extramedullary hematopoiesis can be sufficient for a correct diagnosis and for a radiotherapy treatment, demanding surgery in the case of diagnostic doubts, massive hemorrahages or neurological decifits caused by the focal lesions.

The Parsec-Scale Morphology of Southern GPS Sources

NASA Astrophysics Data System (ADS)

Edwards, P. G.; Tingay, S. J.

2016-12-01

Multi-frequency, multi-epoch ATCA observations of a sample of AGN resulted in the identification of nine new candidate Giga-hertz Peaked Spectrum sources. Here, we present Long Baseline Array observations at 4.8 GHz of the four candidates with no previously published VLBI image, and consider these together with previously published VLBI images of the other five sources. We find core-jet or compact double morphologies dominate, with further observations required to distinguish between these two possibilities for some sources. One of the nine candidates, PKS 1831-711, displays appreciable variability, suggesting its GPS spectrum is more ephemeral in nature. We focus in particular on the apparent relationship between a narrow spectral width and `compact double' parsec-scale morphology, finding further examples, but also exceptions to this trend. An examination of the VLBI morphologies high-redshift (z > 3) sub-class of GPS sources suggests that core-jet morphologies predominate in this class.

Experiment K-6-07. Metabolic and morphologic properties of muscle fibers after spaceflight

The present study demonstrates that the general capability of skeletal muscle to maintain its proteins decreases rapidly in response to space flight. The present findings suggest further that the magnitude of enzymatic and cell volumes changes in response to space flight depend on several factors including the muscle and its fiber type composition. It appears that in order to associate physiological relevance to the observed enzymatic changes, cell volume should be considered also. Although it remains unclear as to the stimulus, or lack of stimulus, that triggers the rapid changes in muscle proteins in response to space flight, ground-based models of muscle atrophy suggest that the reduction in mechanical loading of muscle may be more important than the total amount of activation over a 24-hr period.

Cultural effect on perspective taking in Chinese-English bilinguals.

PubMed

Luk, Kevin K S; Xiao, Wen S; Cheung, Him

2012-09-01

Some recent evidence has suggested that perspective taking skills in everyday life situations may differ across cultural groups. In the present study, we investigated this effect via culture priming in a group of Chinese-English bilingual adults in the context of a communication game. Results showed that the participants made more perspective taking errors when interpreting the game instruction under the Western than the Chinese primes. The findings suggest that the ability to assume others' mental states not only can be used strategically but is also influenced by the currently active cultural frame in the mind of the bilingual. The present study provides the first evidence for a cultural effect on perspective taking using a within-sample approach via culture priming. Copyright © 2012 Elsevier B.V. All rights reserved.

Increased anxiety but normal fear and safety learning in orexin-deficient mice.

Khalil, Radwa; Fendt, Markus

2017-03-01

The loss of orexin neurons in humans leads to the disease narcolepsy, characterized by daytime sleepiness and cataplexy. Recent data suggest that orexin is also involved in emotional processing. The goal of the present study was to evaluate fear and safety learning as well as unconditioned fear (anxiety) in orexin-deficient animals. Orexin-deficient mice are an established animal model used to investigate the neuropathology and potential treatments for narcolepsy. Here, we present novel data showing that orexin-deficient mice express increased anxiety in the open field, light-dark box test and carnivore odor-induced avoidance, but are normal in fear and safety learning. These findings suggest an important role of orexin in brain areas involved in anxiety. Copyright © 2016 Elsevier B.V. All rights reserved.

Stopping the past from intruding the present: Social anxiety disorder and proactive interference.

PubMed

Moore, Harry T A; Gómez-Ariza, Carlos J; Garcia-Lopez, Luis-Joaquín

2016-04-30

It has recently been suggested that social anxiety disorder (SAD) entails a deficit in downregulating unwanted (even non-threatening) memories. In the present study we test this hypothesis by comparing a sample of young adults diagnosed with SAD and healthy controls in their ability to resist proactive interference in a working memory task. Where participants performed similarly in the control condition of the memory task, participants with SAD were more susceptible to interference in the experimental condition than the healthy controls. This finding is in line with previous studies that show anxiety to be associated with impoverished executive control and, specifically, suggests that SAD entails a reduced ability to get rid of interfering memories. Clinical implications are discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Early False-Belief Understanding.

PubMed

Scott, Rose M; Baillargeon, Renée

2017-04-01

Intense controversy surrounds the question of when children first understand that others can hold false beliefs. Results from traditional tasks suggest that false-belief understanding does not emerge until about 4 years of age and constitutes a major developmental milestone in social cognition. By contrast, results from nontraditional tasks, which have steadily accumulated over the past 10 years, suggest that false-belief understanding is already present in infants (under age 2 years) and toddlers (age 2-3 years) and thus forms an integral part of social cognition from early in life. Here we first present an overview of the findings from nontraditional tasks. We then return to traditional tasks and argue that processing difficulties, rather than limitations in false-belief understanding, account for young children's failure at these tasks.

Schwab, Nicholas G; Cullum, Jerry C; Harton, Helen C

2016-01-01

The present study investigated the potential clustering of worry appraisals within college social networks. Participants living in campus residence buildings responded to online surveys across the course of several months. Worry appraisals were measured 10 weeks into the fall semester and again approximately 6 months later. Analysis of sociometric data suggests that the majority of participants' social interactions occurred within their respective residence building floors, indicating that proximity strongly influenced the development of social network ties and sources of social influence. Further, significant clustering of worry appraisals occurred across time, and more importantly, within residence building floors. The present findings compliment previous work suggesting that several physical and psychological states appear to spread and cluster within social networks. Implications for the study of emotional appraisals and future research are discussed.

Oedema of the abductor digiti quinti muscle due to subacute denervation: report of two cases.

PubMed

Chimutengwende-Gordon, Mukai; O'Donnell, Paul; Cullen, Nicholas; Singh, Dishan

2014-03-01

The clinical presentation of abductor digiti quinti (ADQ) denervation is often non-specific. The diagnosis is generally clinical and may be easily missed. This case report of two patients describes the magnetic resonance imaging (MRI) finding of unilateral oedema and fatty infiltration isolated to the ADQ. A 36-year old woman who presented with laterally located left foot pain was initially diagnosed as having plantar fasciitis. An MRI scan arranged due to the unusual site of the pain showed increased signal intensity within the ADQ muscle on T1 and T2 images indicating fatty infiltration. Short tau inversion recovery (STIR) images showed hyperintensity of the ADQ indicating oedema. The MRI scan of a 45-year old man who presented with a three month history of left heel pain revealed similar findings. These MRI appearances indicate subacute denervation, which, when involving solely the ADQ muscle suggests entrapment of the first branch of the lateral plantar nerve. Consideration of this imaging finding when examining MRI scans of patients with non-specific heel pain has the potential to facilitate diagnosis. Copyright © 2013 European Foot and Ankle Society.

Examining the role of interrogative suggestibility in Miranda rights comprehension in adolescents.

PubMed

McLachlan, Kaitlyn; Roesch, Ronald; Douglas, Kevin S

2011-06-01

This study aimed to further clarify the association between interrogative suggestibility and Miranda rights comprehension in adolescents; in particular, we examined whether intellectual ability (IQ) serves as a mediator of this relationship. Participants completed Grisso's Miranda Instruments, the Wechsler Abbreviated Scale of Intelligence, and the Gudjonsson Suggestibility Scale. Many youth demonstrated poor comprehension of their rights, particularly younger and less intellectually capable adolescents. Both yield and shift components of interrogative suggestibility were inversely related to rights comprehension; however, IQ fully mediated these relationships. Neither demographic variables (gender, ethnicity, socio-economic status after controlling for IQ, and English as a second language (ESL) status) nor previous police experience were significantly associated with rights comprehension in the present sample. The implications of these findings are discussed.

Across 3 exploratory and 2 confirmatory preregistered experiments we examined whether impulsive food choice can be trained. Participants were cued to make motor responses upon the presentation of, among others, healthy and sustainable food items. They subsequently selected these food items more often for actual consumption when they needed to make their choices impulsively as a result of time pressure. This effect disappeared when participants were asked to think about their choices, merely received more time to make their choices, or when choosing required attention to alternatives. Participants preferred high to low valued food items under time pressure and without time pressure, suggesting that the impulsive choices reflect valid preferences. These findings demonstrate that it is possible to train impulsive choices for food items while leaving deliberative choices for these items unaffected, and connect research on attention training to dual-process theories of decision making. The present research suggests that attention training may lead to behavioral change only when people behave impulsively. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This article reviews existing research at the intersection of genetics and economics, presents some new findings that illustrate the state of genoeconomics research, and surveys the prospects of this emerging field. Twin studies suggest that economic outcomes and preferences, once corrected for measurement error, appear to be about as heritable as many medical conditions and personality traits. Consistent with this pattern, we present new evidence on the heritability of permanent income and wealth. Turning to genetic association studies, we survey the main ways that the direct measurement of genetic variation across individuals is likely to contribute to economics, and we outline the challenges that have slowed progress in making these contributions. The most urgent problem facing researchers in this field is that most existing efforts to find associations between genetic variation and economic behavior are based on samples that are too small to ensure adequate statistical power. This has led to many false positives in the literature. We suggest a number of possible strategies to improve and remedy this problem: (a) pooling data sets, (b) using statistical techniques that exploit the greater information content of many genes considered jointly, and (c) focusing on economically relevant traits that are most proximate to known biological mechanisms.

The present findings suggest that the trend toward greater diversification of hospital services is likely to be most strongly influenced by state Medicaid policies and certain hospital characteristics. Increasing Medicaid eligibility and payment levels is likely to have a positive effect on services diversification. Growth in the number of inpatient services provided and a more severe case mix are also likely to be involved with greater service diversification. Affiliation with a not-for-profit hospital system is likely to be associated with more diversified hospital services but not affiliation with an investor-owned system. There is also some indication that the overall portfolio of services which a hospital offers in regard to market share and market growth characteristics influences diversification. Specifically, a low market share portfolio is likely to be associated with less diversification. Competition is likely to be associated with more diversification; particularly for hospitals belonging to systems. The effect of competition on hospital strategy and services diversification is a particularly important area for further investigation. Increasing Medicaid payment and eligibility levels are also likely to have a positive effect on the provision of services which are usually unprofitable. Raising such levels is likely to be particularly beneficial to inner-city hospitals who are already providing a greater number of such services. However, the present data suggest that investor-owned hospitals are least likely to provide such services. Increasing Medicaid eligibility levels is also likely to be associated with fewer services for which charity care has to be provided. State regulation in the form of rate review and certificate of need is likely to be associated with more services for which hospitals provide some charity care. But such policies alone do not deal with the larger issue of how to finance care for the medically indigent. Present data suggest the charity care issue may be particularly salient in markets characterized by a relatively high degree of competition. Finally, investor-owned hospitals provide as many services involving charity care as not-for-profit system hospitals, although investor-owned system hospitals provide fewer such services than not-for-profit freestanding hospitals. Throughout, the findings indicate the importance of distinguishing between ownership and system affiliation. Previous research has failed to make a distinction between ownership form and system affiliation, thus attributing to ownership form differences which, as present findings suggest, appear to be more associated with system affiliation.(ABSTRACT TRUNCATED AT 400 WORDS)

Validity of a test of children's suggestibility for predicting responses to two interview situations differing in their degree of suggestiveness.

In the present study the relative contributions of internal and external sources of variation in children's suggestibility in interrogative situations were examined. One hundred and eleven children (48 4- to 5-year-olds and 63 7- to 8-year-olds) were administered a suggestibility test (BTSS) and the most suggestible (N=36) and the least suggestible (N=36) children were randomly assigned to either an interview condition containing several suggestive techniques or to one containing only suggestive questions. The effects of internal sources of variation in suggestibility were compared with the effects of the interview styles on the children's answers. The former did influence the children, but the external sources of variation in suggestibility had a stronger impact. Influences of cognitive, developmental factors could be found, but not when abuse-related questions were asked and high pressured interview methods were used. These findings indicate that individual assessment of suggestibility can be of some assistance when interviewing children, but diminishing suggestive influences in interrogations must be given priority.

Search asymmetry and eye movements in infants and adults.

PubMed

Adler, Scott A; Gallego, Pamela

Search asymmetry is characterized by the detection of a feature-present target amidst feature-absent distractors being efficient and unaffected by the number of distractors, whereas detection of a feature-absent target amidst feature-present distractors is typically inefficient and affected by the number of distractors. Although studies have attempted to investigate this phenomenon with infants (e.g., Adler, Inslicht, Rovee-Collier, & Gerhardstein in Infant Behavioral Development, 21, 253-272, 1998; Colombo, Mitchell, Coldren, & Atwater in Journal of Experimental Psychology: Learning, Memory and Cognition, 19, 98-109, 1990), due to methodological limitations, their findings have been unable to definitively establish the development of visual search mechanisms in infants. The present study assessed eye movements as a means to examine an asymmetry in responding to feature-present versus feature-absent targets in 3-month-olds, relative to adults. Saccade latencies to localize a target (or a distractor, as in the homogeneous conditions) were measured as infants and adults randomly viewed feature-present (R among Ps), feature-absent (P among Rs), and homogeneous (either all Rs or all Ps) arrays at set sizes of 1, 3, 5, and 8. Results indicated that neither infants' nor adults' saccade latencies to localize the target in the feature-present arrays were affected by increasing set sizes, suggesting that localization of the target was efficient. In contrast, saccade latencies to localize the target in the feature-absent arrays increased with increasing set sizes for both infants and adults, suggesting an inefficient localization. These findings indicate that infants exhibit an asymmetry consistent with that found with adults, providing support for functional bottom-up selective attention mechanisms in early infancy.

In 2016, gay, bisexual, and other men who have sex with men (MSM) comprise more than half of all new HIV diagnoses in the United States, with the primary mode of infection being condomless anal sex (CAS). While studies report an association between use of Internet-based social networking sites and increased CAS, the research on the relationship between cell phone mobile applications (e.g., Grindr, Scruff, Jack'd) and CAS is much less developed. The present study examines whether the manner in which gay, bisexual, and other MSM find sexual partners predicts an increase in likelihood of engaging in CAS in an urban, noncoastal U.S. city. Conducting a secondary data analysis of the 2011 National HIV Behavioral Surveillance survey for Denver ( N = 546), the authors performed binary logistic regression analyses to assess the models that predict how MSM find sexual partners, and the odds of engaging in CAS. While the results suggest that age and race are associated with the mode of finding sexual partners, using the Internet or a mobile app to find sexual partners was not predictive of CAS ( Z Wald = .41, p = .52; Z Wald = .80, p = .37). In terms of HIV prevention, these findings suggest a need for intervention to address HIV prevention on multiple levels (e.g., individual, group, community).

Emotion Induced Blindness Is More Sensitive to Changes in Arousal As Compared to Valence of the Emotional Distractor

PubMed Central

Singh, Divita; Sunny, Meera M.

2017-01-01

Emotion Induced Blindness (EIB) refers to the impairment in the identification of a neutral target image that follows a threatening or fearful distractor image. It has been suggested that valence plays a significant role in driving the perceptual impairment in EIB. Recent findings from the literature suggest that arousal has a very important role in biasing early cognitive functions. Hence, in the present study, we systematically investigate the role of valence (Experiment 1) and arousal (Experiment 2) in determining the impairment in EIB. The results suggest that when valence is controlled for, the stimuli with higher arousal level lead to greater impairment in target detection. Moreover, under high arousal condition, both positive and negative stimuli lead to significantly greater impairment in target detection. Present study suggests that impairment in EIB is sensitive to the arousal component of the emotional image as compared to valence. The arousal biased competition account that explains the effect of arousal on cognitive processing can sufficiently explains the current results. PMID:28861017

Reproductive ambition predicts partnered, but not unpartnered, women's preferences for masculine men.

PubMed

Watkins, Christopher D

2012-08-01

Changing circumstances alter the costs and benefits of choosing different mates and are thought to be reflected in women's mate preferences. Indeed, several lines of reasoning, and some prior studies, suggest that individual differences in women's preferences for cues of men's underlying health will be more apparent among partnered women than among unpartnered women. The current study shows that preferences for male faces with masculine shape cues, characteristics that are thought to signal men's underlying health, are positively correlated with partnered, but not unpartnered, women's reported reproductive ambition (i.e., their desire to become pregnant). These findings (1) present new evidence for systematic variation in women's mating strategies, (2) suggest that partnership status may be important for potentially adaptive variation in women's mate preferences, and (3) suggest that reproductive ambition may influence women's mate preferences. Alternative explanations for these findings, focusing on the possible effects of a range of variables that may be correlated with reproductive ambition in partnered women and influence their masculinity preferences, are also discussed. ©2011 The British Psychological Society.

Objective The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5%) patients (mean age, 50.9 years; age range, 42-58 years; 42% female). Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

Impact of problem finding on the quality of authentic open inquiry science research projects

Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

Learned perceptual associations influence visuomotor programming under limited conditions: kinematic consistency.

PubMed

Haffenden, Angela M; Goodale, Melvyn A

2002-12-01

Previous findings have suggested that visuomotor programming can make use of learned size information in experimental paradigms where movement kinematics are quite consistent from trial to trial. The present experiment was designed to test whether or not this conclusion could be generalized to a different manipulation of kinematic variability. As in previous work, an association was established between the size and colour of square blocks (e.g. red = large; yellow = small, or vice versa). Associating size and colour in this fashion has been shown to reliably alter the perceived size of two test blocks halfway in size between the large and small blocks: estimations of the test block matched in colour to the group of large blocks are smaller than estimations of the test block matched to the group of small blocks. Subjects grasped the blocks, and on other trials estimated the size of the blocks. These changes in perceived block size were incorporated into grip scaling only when movement kinematics were highly consistent from trial to trial; that is, when the blocks were presented in the same location on each trial. When the blocks were presented in different locations grip scaling remained true to the metrics of the test blocks despite the changes in perceptual estimates of block size. These results support previous findings suggesting that kinematic consistency facilitates the incorporation of learned perceptual information into grip scaling.

Samples were collected in 2011 from tomato plants exhibiting typical tomato leaf curl disease symptoms in the vicinity of Komae, Japan. PCR mediated amplification, cloning and sequencing of all begomovirus components from two plants from different fields showed the plants to be infected by Tomato yellow leaf curl virus (TYLCV) and Ageratum yellow vein virus (AYVV). Both viruses have previously been shown to be present in Japan, although this is the first identification of AYVV on mainland Japan; the virus previously having been shown to be present on the Okinawa Islands. The plant harboring AYVV was also shown to contain the betasatellite Tomato leaf curl Java betasatellite (ToLCJaB), a satellite not previously shown to be present in Japan. No betasatellite was associated with the TYLCV infected tomato plants analyzed here, consistent with earlier findings for this virus in Japan. Surprisingly both plants were also found to harbor an alphasatellite; no alphasatellites having previously been reported from Japan. The alphasatellite associated with both viruses was shown to be Sida yellow vein China alphasatellite which has previously only been identified in the Yunnan Province of China and Nepal. The results suggest that further begomoviruses, and their associated satellites, are being introduced to Japan. The significance of these findings is discussed.

Previous findings suggest that negative emotions could influence abnormal sensory perception in burning mouth syndrome (BMS). However, few studies have investigated the underlying neural mechanisms associated with BMS. We examined activation of brain regions in response to intraoral tactile stimuli when modulated by angry facial expressions. We performed functional magnetic resonance imaging on a group of 27 BMS patients and 21 age-matched healthy controls. Tactile stimuli were presented during different emotional contexts, which were induced via the continuous presentation of angry or neutral pictures of human faces. BMS patients exhibited higher tactile ratings and greater activation in the postcentral gyrus during the presentation of tactile stimuli involving angry faces relative to controls. Significant positive correlations between changes in brain activation elicited by angry facial images in the postcentral gyrus and changes in tactile rating scores by angry facial images were found for both groups. For BMS patients, there was a significant positive correlation between changes in tactile-related activation of the postcentral gyrus elicited by angry facial expressions and pain intensity in daily life. Findings suggest that neural responses in the postcentral gyrus are more strongly affected by angry facial expressions in BMS patients, which may reflect one possible mechanism underlying impaired somatosensory system function in this disorder.

Axillary lymph node metastasis from an occult breast carcinoma is a rare occurrence. We report this condition in a 59-year-old woman who presented with a swelling in the right axilla. No breast mass was clinically evident. Mammography, ultrasonography and multiple random fine-needle breast biopsies yielded no pathological findings. No extramammary primary lesions were present. Axillary sampling was performed and histological examination revealed the presence of metastatic adenocarcinoma in three of the 12 dissected lymph nodes. Estrogen receptors were positive and immunohistochemistry pointed to a breast origin. All these data were suggestive of occult breast cancer. The patient refused any further treatment but accepted clinical and radiological follow-up. Eight years later mammography revealed in the same breast a 10-mm nodule containing microcalcifications, which was not evident at physical examination. The patient underwent a lumpectomy. Intraoperative histology was positive for breast carcinoma and complete axillary clearance was performed. Histological examination revealed a lobular invasive breast carcinoma and the presence of micrometastasis in one of the 23 removed lymph nodes. The patient was given radiotherapy to the breast and axilla and tamoxifen. At present, one year after the appearance of the primary tumor, she is free of disease. Based on this case report we suggest an eclectic approach in the management of patients with axillary metastasis from occult breast cancer, depending on the clinical, pathological and biological findings.

Approximately 1.7 million children have parents who are incarcerated in prison in the United States, and possibly millions of additional children have a parent incarcerated in jail. Many affected children experience increased risk for developing behavior problems, academic failure, and substance abuse. For a growing number of children, incarcerated parents, caregivers, and professionals, parent-child contact during the imprisonment period is a key issue. In this article, we present a conceptual model to provide a framework within which to interpret findings about parent-child contact when parents are incarcerated. We then summarize recent research examining parent-child contact in context. On the basis of the research reviewed, we present initial recommendations for children's contact with incarcerated parents and also suggest areas for future intervention and research with this vulnerable population.

Recent findings show that people with dyslexia have an impairment in serial-order memory. Based on these findings, the present study aimed to test the hypothesis that people with dyslexia have difficulties dealing with proactive interference (PI) in recognition memory. A group of 25 adults with dyslexia and a group of matched controls were subjected to a 2-back recognition task, which required participants to indicate whether an item (mis)matched the item that had been presented 2 trials before. PI was elicited using lure trials in which the item matched the item in the 3-back position instead of the targeted 2-back position. Our results demonstrate that the introduction of lure trials affected 2-back recognition performance more severely in the dyslexic group than in the control group, suggesting greater difficulty in resisting PI in dyslexia.

Meta-analyses confirm a negative relationship between aggressive behavior and empathy, that is, the ability to understand and share the feelings of others. Based on theoretical considerations, it was, therefore, hypothesized that a lack of empathic responsiveness may be characteristic for cyberbullies in particular. In the present study, 2.070 students of Luxembourg secondary schools completed an online survey that included a cyberbullying questionnaire(4) and a novel empathy short scale. According to the main hypothesis, analyses of variances indicated that cyberbullies demonstrated less empathic responsiveness than non-cyberbullies. In addition, cyberbullies were also more afraid of becoming victims of cyberbullying. The findings confirm and substantially extend the research on the relationship between empathy and aggressive behavior. From an educational point of view, the present findings suggest that training of empathy skills might be an important tool to decrease cyberbullying.

To describe a case of unilateral comeal keloid and present the clinical and histopathological findings and the management. A 23-year-old Asian male patient was examined for a white spot on the left cornea that had been present since birth. On biomicroscopic examination, a well-demarcated vascularized comeal mass was found located nasal to the center. The pupil was displaced superiorly, and gonioscopic examination showed peripheral iridocomeal adhesion at 12 o'clock. The patient underwent penetrating keratoplasty. Histopathologic study showed a variously thickened epithelial layer, an absence of Bowman's layer, subepithelial fibrovascular hyperplasia, and an absence of dermal elements. These histopathologic findings suggested a congenital comeal keloid. The central graft comea remained clear at 18 months after surgery and the patient was satisfied with the result. Penetrating keratoplasty may be an effective surgical option for congenital keloids in young adult patients.

Leigh syndrome, which is a common phenotype of pediatric mitochondrial disease, is a progressive neurodegenerative disease. The typical neuroimaging findings of Leigh syndrome include bilateral symmetric lesions in the basal ganglia and/or the brainstem. However, there are a few reports on spinal cord involvement in patients with Leigh syndrome. In the present case, magnetic resonance imaging (MRI) obtained during infancy revealed symmetric lesions in the substantia nigra of a patient with Leigh syndrome with an NDUFA1 mutation; lesions of the bilateral putamen and brainstem were subsequently observed. Additionally, our patient presented large and extended spinal cord lesions. Therefore, this case is suggesting that we should consider the occurrence of spinal cord lesions as an atypical finding in Leigh syndrome. Copyright © 2018 The Japanese Society of Child Neurology.

Neural signatures of conscious and unconscious emotional face processing in human infants.

PubMed

Jessen, Sarah; Grossmann, Tobias

2015-03-01

Human adults can process emotional information both with and without conscious awareness, and it has been suggested that the two processes rely on partly distinct brain mechanisms. However, the developmental origins of these brain processes are unknown. In the present event-related brain potential (ERP) study, we examined the brain responses of 7-month-old infants in response to subliminally (50 and 100 msec) and supraliminally (500 msec) presented happy and fearful facial expressions. Our results revealed that infants' brain responses (Pb and Nc) over central electrodes distinguished between emotions irrespective of stimulus duration, whereas the discrimination between emotions at occipital electrodes (N290 and P400) only occurred when faces were presented supraliminally (above threshold). This suggests that early in development the human brain not only discriminates between happy and fearful facial expressions irrespective of conscious perception, but also that, similar to adults, supraliminal and subliminal emotion processing relies on distinct neural processes. Our data further suggest that the processing of emotional facial expressions differs across infants depending on their behaviorally shown perceptual sensitivity. The current ERP findings suggest that distinct brain processes underpinning conscious and unconscious emotion perception emerge early in ontogeny and can therefore be seen as a key feature of human social functioning.

Evaluation of Oral Anticoagulant-Associated Intracranial Parenchymal Hematomas Using CT Findings.

Gökçe, E; Beyhan, M; Acu, B

2015-06-01

Intracranial hemorrhage (ICH) is one of the most serious and lethal complications of anticoagulants with a reported incidence of 5-18.5 %. Computed tomographic (CT) findings, should be carefully studied because early diagnosis and treatment of oral anticoagulant use-associated hematomas are vitally important. In the present study, CT findings of intraparenchymal hematomas associated with anticoagulant and antihypertensive use are presented. This study included 45 patients (25 men, 20 women) under anticoagulant (21 patients) or antihypertensive (24 patients) treatment who had brain CT examinations due to complaints and findings suggesting cerebrovascular disease during July 2010-October 2013 period. CT examinations were performed to determine hematoma volumes and presence of swirl sign, hematocrit effect, mid-line shift effect, and intraventricular extension. The patients were 40-89 years of age. In four cases, a total of 51 intraparenchymal hematomas (42 cerebral, 7 cerebellar and 2 brain stem) were detected in multiple foci. Hematoma volumes varied from 0.09 to 284.00 ml. Swirl sign was observed in 87.5 and 63.0 % of OAC-associated ICHs and non-OAC-associated ICHs, respectively. In addition, hematocrit effect was observed in 41.6 % of OAC-associated and in 3.7 % of non-OAC-associated ICHs. Volume increases were observed in all 19 hematomas where swirl sign was detected, and follow-up CT scanning was conducted. Mortality of OAC-associated ICHs was correlated with initial volumes of hematoma, mid-line shift amount, and intraventricular extension. Detection of hematocrit effect by CT scanning of intracranial hematomas should be cautionary in oral anticoagulant use, while detection of swirl sign should be suggestive of active hemorrhage.

Abnormal immune system development and function in schizophrenia helps reconcile diverse findings and suggests new treatment and prevention strategies.

Extensive research implicates disturbed immune function and development in the etiology and pathology of schizophrenia. In addition to reviewing evidence for immunological factors in schizophrenia, this paper discusses how an emerging model of atypical immune function and development helps explain a wide variety of well-established - but puzzling - findings about schizophrenia. A number of theorists have presented hypotheses that early immune system programming, disrupted by pre- and perinatal adversity, often combines with abnormal brain development to produce schizophrenia. The present paper focuses on the hypothesis that disruption of early immune system development produces a latent immune vulnerability that manifests more fully after puberty, when changes in immune function and the thymus leave individuals more susceptible to infections and immune dysfunctions that contribute to schizophrenia. Complementing neurodevelopmental models, this hypothesis integrates findings on many contributing factors to schizophrenia, including prenatal adversity, genes, climate, migration, infections, and stress, among others. It helps explain, for example, why (a) schizophrenia onset is typically delayed until years after prenatal adversity, (b) individual risk factors alone often do not lead to schizophrenia, and (c) schizophrenia prevalence rates actually tend to be higher in economically advantaged countries. Here we discuss how the hypothesis explains 10 key findings, and suggests new, potentially highly cost-effective, strategies for treatment and prevention of schizophrenia. Moreover, while most human research linking immune factors to schizophrenia has been correlational, these strategies provide ethical ways to experimentally test in humans theories about immune function and schizophrenia.

Evolved Minimal Frustration in Multifunctional Biomolecules.

PubMed

Röder, Konstantin; Wales, David J

2018-05-25

Protein folding is often viewed in terms of a funnelled potential or free energy landscape. A variety of experiments now indicate the existence of multifunnel landscapes, associated with multifunctional biomolecules. Here, we present evidence that these systems have evolved to exhibit the minimal number of funnels required to fulfil their cellular functions, suggesting an extension to the principle of minimum frustration. We find that minimal disruptive mutations result in additional funnels, and the associated structural ensembles become more diverse. The same trends are observed in an atomic cluster. These observations suggest guidelines for rational design of engineered multifunctional biomolecules.

Caffeine-induced psychiatric manifestations: a review.

The association between caffeine consumption and various psychiatric manifestations has long been observed. We present two cases that show the ability of caffeine to induce psychotic and manic symptoms, and we also review the extant literature on caffeine-induced psychiatric manifestations. On the basis of our own and others' findings, we suggest that caffeine may be related to not only de-novo psychotic or mood symptoms but also to aggravation of pre-existing psychotic or mood disorders. We therefore suggest that caffeine consumption among patients with mood or psychotic symptoms should be assessed carefully in clinical practice as part of routine psychiatric evaluations.

Sensitization and histamine release by cells of the sand dollar, Mellita quinquiesperforata.

PubMed

Smith, S L; Smith, A C

The coelomic fluid of the sand dollar, Mellita quinquiesperforata, contains cells (coelomocytes) that release red granules when the animal is stressed. Preliminary evidence suggests that the red pigment is protective, but its release from the coelomocytes is similar to that of allergy-inducing mediators from mammalian basophils and mast cells. The present study revealed further links with allergy, e.g., the coelomocytes can be sensitized to foreign proteins and release histamine on challenge. These and other findings suggest that the coelomocyte stress response may be an evolutionary precursor to the mammalian allergic response.

Four young patients who presented with pain over the anterior compartment of the legs, gave a recent athletic history suggesting stress fractures. Although radiographs were initially normal in all four cases, the bone scintigrams were positive. The individual findings, however, were quite different. In one there was a single focal area of increased radioactivity in each of the tibias; the second patient had uneven uptake of radiotracer and several foci of accumulation in the fibulas; the third showed diffuse linear tibial uptake suggesting periosteal lesions; and the fourth case revealed uptake in the lateral malleolus and in bones of the foot.

Primary headaches among children and adolescents have a substantial impact on quality of life, daily activities, social interaction, and school performance in combination with psychopathological symptoms. The main purpose of the present paper is to summarize clinical and epidemiological evidence for psychiatric comorbidity among children and adolescents with headaches, to describe how evidence in headache research suggest different pathways involved in the development and maintenance of these comorbid conditions, and finally suggest some elements professionals may find helpful to assess the scope of complaints, related functional impairment, and potential precipitating factors in planning of more targeted treatments.

The aim of this study was to analyze the clinical, pathological, and CT-enterography findings of small bowel adenocarcinomas in Crohn disease patients. Clinical, histopathological, and imaging findings were retrospectively evaluated in seven Crohn disease patients with small bowel adenocarcinoma. CT-enterography examinations were reviewed for morphologic features and location of tumor, presence of stratification, luminal stenosis, proximal dilatation, adjacent lymph nodes, and correlated with findings at histological examination. The tumor was located in the terminal (n = 6) or distal (n = 1) ileum. On CT-enterography, the tumor was visible in five patients, whereas two patients had no visible tumor. Four different patterns were individualized including small bowel mass (n = 2), long stenosis with heterogeneous submucosal layer (n = 2), short and severe stenosis with proximal small bowel dilatation (n = 2), and sacculated small bowel loop with irregular and asymmetric circumferential thickening (n = 1). Stratification, fat stranding, and comb sign were present in two, two, and one patients, respectively. Identification of a mass being clearly visible suggests strongly the presence of small bowel adenocarcinoma in Crohn disease patients but adenocarcinoma may be completely indistinguishable from benign fibrotic or acute inflammatory stricture. Knowledge of these findings is critical to help suggest the diagnosis of this rare but severe complication of Crohn disease.

Standard 12-lead electrocardiography is used to diagnose acute myocardial infarctions in patient presenting with ST elevation. The specificity of ST segment elevation for the corresponding area is more than 90 percent. It has been suggested that ST-segment elevation in lead aVR may indicate left main disease. We will present a patient who had an ST segment elevation in this lead. We will review the current data about this finding, as well as the significance of ST segment elevation in other leads.

On Multiple-Layered Vortices

2011-01-01

As part of an ongoing effort to find ways to make vortex flow fields decompose more quickly, photographs and observations are presented of vortex flow fields that indicate the presence of multiple layers of fluid rotating about a common axis. A survey of the literature indicates that multiple-layered vortices form in waterspouts, tornadoes and lift-generated vortices of aircraft. An explanation for the appearance of multiple-layered structures in vortices is suggested. The observations and data presented are intended to improve the understanding of the formation and persistence of vortex flow fields.

Pathological Laughing: Brain SPECT Findings.

We present the case of a 40-year-old man consulting for uncontrollable episodes of laughing related to emotional lability and not systematically linked to feelings of happiness. Seven months earlier he had presented a pontine ischemic stroke related to an occlusion of the basilar and left vertebral arteries. No epileptic activity or new MRI brain lesions were found. Brain perfusion SPECT performed showed marked hypoperfusion in the right frontal inferior and temporoinsular regions, suggesting a diaschisis phenomenon caused by pontine lesions and highlighted laughing regulation pathways. The patient was successfully treated with a serotonergic reuptake inhibitor, fluoxetine.

Ophthalmic manifestations of mucoceles.

Two patients with mucoceles are described. The first case had exophthalmos, and the second had visual loss suggestive of retrobulbar optic neuritis. Possible ocular manifestations of mucoceles are discussed, and the computed tomography findings of these are shown. The treatment of mucoceles is reviewed, and it is stressed that a team approach involving ophthalmology, otorhinolaryngology, and radiology is essential for accurate diagnosis and treatment. Paranasal sinus mucoceles can present with a multitude of different symptoms. The type of presentation is usually determined by the original site of the mucocele, whether it be frontal, ethmoidal, or sphenoidal.

Positive health practices and temporal perspective in low-income adults.

Thompson, Cheryl W; Fitzpatrick, Joyce J

2008-07-01

The purpose of this study was to describe health-promoting behaviours and temporal perspective in low-income adults. Positive health practices represent a broad range of health-promoting behaviours. The ability to adopt positive health practices may be influenced by many factors, one of which is temporal perspective, the perceived relationship between past, present and future times. This exploratory study was conducted in a south central Pennsylvania community with a convenience sample of individuals who were eligible for a subsidized low-income housing programme. Positive health practices were measured using the Personal Lifestyle Questionnaire. Temporal perspective was measured with the Circles Test. The sample consisted of 75 subjects, 61 women (81%) and 14 men (19%). Positive health practices were relatively high (mean = 70 out of a possible score of 96). Forty three per cent of the subjects expressed future temporal dominance and 80% of the subjects in this study expressed non-continuous temporal relatedness. Health-promoting behaviours in this low-income sample were similar to those reported in other samples in middle-class adult samples. The percentage of subjects who expressed future dominance was similar to findings in other samples. The percentage of subjects who expressed non-continuous temporal relatedness was different from findings reported in other samples, suggesting that perception of the relationship of past, present and future times is different in this low-income sample compared with other samples. The temporal relatedness findings suggest that low-income individuals may not believe that adopting positive health practices will influence future health.

Do neural correlates of face expertise vary with task demands? Event-related potential correlates of own- and other-race face inversion

PubMed Central

Wiese, Holger

2013-01-01

We are typically more accurate at remembering own- than other-race faces. This “own-race bias” has been suggested to result from enhanced expertise with and more efficient perceptual processing of own-race than other-race faces. In line with this idea, the N170, an event-related potential correlate of face perception, has been repeatedly found to be larger for other-race faces. Other studies, however, found no difference in N170 amplitude for faces from diverse ethnic groups. The present study tested whether these seemingly incongruent findings can be explained by varying task demands. European participants were presented with upright and inverted European and Asian faces (as well as European and Asian houses), and asked to either indicate the ethnicity or the orientation of the stimuli. Larger N170s for other-race faces were observed in the ethnicity but not in the orientation task, suggesting that the necessity to process facial category information is a minimum prerequisite for the occurrence of the effect. In addition, N170 inversion effects, with larger amplitudes for inverted relative to upright stimuli, were more pronounced for own- relative to other-race faces in both tasks. Overall, the present findings suggest that the occurrence of ethnicity effects in N170 for upright faces depends on the amount of facial detail required for the task at hand. At the same time, the larger inversion effects for own- than other-race faces occur independent of task and may reflect the fine-tuning of perceptual processing to faces of maximum expertise.

Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an active pharmaceutical ingredient (API) when immediate-release as well as extended-release formulations were on the market together (fourth quarter of 2011 to second quarter of 2016). Tapentadol (API) was compared with tramadol, hydrocodone, morphine, oxycodone, hydromorphone, and oxymorphone across Poison Center, Drug Diversion, and Treatment Center Programs Combined data streams from the Researched Abuse, Diversion and Addiction-Related Surveillance system. Findings suggest the public health burden related to tapentadol to date is low, but present. Event rates of abuse per population-level denominators were significantly lower than all other opioids examined. However, when adjusted for drug availability, event rates of abuse were lower than most Schedule II opioids studied, but were not the lowest. Disentangling these 2 sets of findings further by examining various opioid formulations, such as extended-release and the role of abuse-deterrent formulations, is warranted. This article presents the results from an examination of tapentadol API across the Researched Abuse, Diversion and Addiction-Related Surveillance System: a broad and carefully designed postmarketing mosaic. Data to date from Poison Center, Drug Diversion, and Treatment Centers combined suggest a low, but present public health burden related to tapentadol. Copyright © 2018. Published by Elsevier Inc.

Using future thinking to reduce temporal discounting: Under what circumstances are the medial temporal lobes critical?

PubMed

Palombo, D J; Keane, M M; Verfaellie, M

2016-08-01

The capacity to envision the future plays an important role in many aspects of cognition, including our ability to make optimal, adaptive choices. Past work has shown that the medial temporal lobe (MTL) is necessary for decisions that draw on episodic future thinking. By contrast, little is known about the role of the MTL in decisions that draw on semantic future thinking. Accordingly, the present study investigated whether the MTL contributes to one form of decision making, namely intertemporal choice, when such decisions depend on semantic consideration of the future. In an intertemporal choice task, participants must select either a smaller amount of money that is available in the present or a larger amount of money that would be available at a future date. Amnesic individuals with MTL damage and healthy control participants performed such a task in which, prior to making a choice, they engaged in a semantic generation exercise, wherein they generated items that they would purchase with the future reward. In experiment 1, we found that, relative to a baseline condition involving standard intertemporal choice, healthy individuals were more inclined to select a larger, later reward over a smaller, present reward after engaging in semantic future thinking. By contrast, amnesic participants were paradoxically less inclined to wait for a future reward following semantic future thinking. This finding suggests that amnesics may have had difficulty "tagging" the generated item(s) as belonging to the future. Critically, experiment 2 showed that when the generated items were presented alongside the intertemporal choices, both controls and amnesic participants shifted to more patient choices. These findings suggest that the MTL is not needed for making optimal decisions that draw on semantic future thinking as long as scaffolding is provided to support accurate time tagging. Together, these findings stand to better clarify the role of the MTL in decision making. Published by Elsevier Ltd.

When language gets emotional: irony and the embodiment of affect in discourse.

PubMed

Filik, Ruth; Hunter, Christian Mark; Leuthold, Hartmut

2015-03-01

Although there is increasing evidence to suggest that language is grounded in perception and action, the relationship between language and emotion is less well understood. We investigate the grounding of language in emotion using a novel approach that examines the relationship between the comprehension of a written discourse and the performance of affect-related motor actions (hand movements towards and away from the body). Results indicate that positively and negatively valenced words presented in context influence motor responses (Experiment 1), whilst valenced words presented in isolation do not (Experiment 3). Furthermore, whether discourse context indicates that an utterance should be interpreted literally or ironically can influence motor responding, suggesting that the grounding of language in emotional states can be influenced by discourse-level factors (Experiment 2). In addition, the finding of affect-related motor responses to certain forms of ironic language, but not to non-ironic control sentences, suggests that phrasing a message ironically may influence the emotional response that is elicited.

Neural correlates of HIV risk feelings.

Häcker, Frank E K; Schmälzle, Ralf; Renner, Britta; Schupp, Harald T

2015-04-01

Field studies on HIV risk perception suggest that people rely on impressions they have about the safety of their partner. The present fMRI study investigated the neural correlates of the intuitive perception of risk. First, during an implicit condition, participants viewed a series of unacquainted persons and performed a task unrelated to HIV risk. In the following explicit condition, participants evaluated the HIV risk for each presented person. Contrasting responses for high and low HIV risk revealed that risky stimuli evoked enhanced activity in the anterior insula and medial prefrontal regions, which are involved in salience processing and frequently activated by threatening and negative affect-related stimuli. Importantly, neural regions responding to explicit HIV risk judgments were also enhanced in the implicit condition, suggesting a neural mechanism for intuitive impressions of riskiness. Overall, these findings suggest the saliency network as neural correlate for the intuitive sensing of risk. © The Author (2014). Published by Oxford University Press.

The Relationships of Working Memory, Secondary Memory, and General Fluid Intelligence: Working Memory is Special

Shelton, Jill Talley; Elliott, Emily M.; Matthews, Russell A.; Hill, B. D.; Gouvier, Wm. Drew

2010-01-01

Recent efforts have been made to elucidate the commonly observed link between working memory and reasoning ability. The results have been inconsistent, with some work suggesting the emphasis placed on retrieval from secondary memory by working memory tests is the driving force behind this association (Mogle, Lovett, Stawski, & Sliwinski, 2008), while other research suggests retrieval from secondary memory is only partly responsible for the observed link between working memory and reasoning (Unsworth & Engle, 2006, 2007b). The present study investigates the relationship between processing speed, working memory, secondary memory, primary memory, and fluid intelligence. Although our findings show all constructs are significantly correlated with fluid intelligence, working memory, but not secondary memory, accounts for significant unique variance in fluid intelligence. Our data support predictions made by Unsworth and Engle, and suggest that the combined need for maintenance and retrieval processes present in working memory tests makes them “special” in their prediction of higher-order cognition.

Contextual modulation of attention in human category learning.

PubMed

George, David N; Kruschke, John K

2012-12-01

In a category-learning experiment, we assessed whether participants were able to selectively attend to different components of a compound stimulus in two distinct contexts. The participants were presented with stimulus compounds for which they had to learn categorical labels. Each compound comprised one feature from each of two dimensions, and on different trials the compound was presented in two contexts, X and Y. In Context X, Dimension A was relevant to the solution of the categorization task and Dimension B was irrelevant, whereas in Context Y, Dimension A was irrelevant and Dimension B was relevant. The results of transfer tests to novel stimuli suggested that people learned to attend selectively to Dimension A in Context X and Dimension B in Context Y. These findings contribute to the growing body of evidence that people can learn to selectively attend to particular dimensions of stimuli dependent on the context in which the stimuli are presented. Furthermore, the findings demonstrate that context-dependent changes in attention transfer to other categorization tasks involving novel stimuli.

Gender Difference of Unconscious Attentional Bias in High Trait Anxiety Individuals

2011-01-01

By combining binocular suppression technique and a probe detection paradigm, we investigated attentional bias to invisible stimuli and its gender difference in both high trait anxiety (HTA) and low trait anxiety (LTA) individuals. As an attentional cue, happy or fearful face pictures were presented to HTAs and LTAs for 800 ms either consciously or unconsciously (through binocular suppression). Participants were asked to judge the orientation of a gabor patch following the face pictures. Their performance was used to measure attentional effect induced by the cue. We found gender differences of attentional effect only in the unconscious condition with HTAs. Female HTAs exhibited difficulty in disengaging attention from the location where fearful faces were presented, while male HTAs showed attentional avoidance of it. Our results suggested that the failure to find attentional avoidance of threatening stimuli in many previous studies might be attributed to consciously presented stimuli and data analysis regardless of participants' gender. These findings also contributed to our understanding of gender difference in anxiety disorder. PMID:21647221

The role of self-esteem in the misinformation effect.

PubMed

Saunders, Jo

2012-01-01

Previous research using the Gudjonnson suggestibility scale has suggested a role for self-esteem in suggestibility, with participants low in self-esteem being more suggestible than participants high in self-esteem. Four experiments are presented examining the role of self-esteem in the misinformation effect and whether enhanced suggestibility effects in participants low in self-esteem reflect genuine memory impairment. In Experiments 1 and 4 participants completed a standard recognition test. In Experiment 2 participants completed the modified recognition test. In Experiment 3 participants completed a free recall test. In Experiments 1 and 4 participants low in self-esteem demonstrated greater misinformation effects than participants high in self-esteem. In Experiment 3 a 3-day retention interval was employed with the modified test and no differences were found between the two groups on the reporting of the new item. The findings suggest that participants low in self-esteem are particularly sensitive to demand characteristics and post-event suggestion but do not suffer from genuine memory impairment.

KILT syndrome is a rare condition composing the triad of kidney and inferior vena cava anomaly and extensive venous thrombosis. We present a case of newly diagnosed KILT syndrome in a 41-years-old gentleman presenting with loin pain and fever. Reviewing previous case reports, KILT syndrome is usually an incidental finding on imaging studies and there is a wide scope of initial clinical presentations. However, recent evidence suggests IVC anomaly may have caused subsequent renal hypoplasia. Identification of the underlying etiology may be helpful in planning early vascular intervention to treat the condition.
