The formal solutions of Diophantine equation agy = bx + c. Heliyon 2024; 10:e24766. [PMID: 38322917 PMCID: PMC10844102 DOI: 10.1016/j.heliyon.2024.e24766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 12/29/2023] [Accepted: 01/14/2024] [Indexed: 02/08/2024] Open
Abstract
We develop a novel method to completely solve the 3-term partial exponential Diophantine equation that represents a generalization of the standard discrete logarithm problem. Our method not only reveals the internal structure of the equation's solution and yields a numerical algorithm to solve it systematically, but also provides an alternative approach to the discrete logarithm problem.

The Patient Experience: The Relationship Between Vocal Handicap, Congruency, Perceived Present Control, and Mood Across Four Voice Disorders. J Voice 2024; 38:244.e15-244.e27. [PMID: 34615615 DOI: 10.1016/j.jvoice.2021.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 08/19/2021] [Accepted: 08/25/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The potential for negative sequalae in psychosocial well-being presents clinical importance to the assessment of voice disorders. Despite the impairment voice disorders cause in the psychosocial domain, the clinical assessment of these disorders relies heavily on visual perceptual judgments of the larynx, audio-perceptual, as well as acoustic and aerodynamic measures. While these measures aid in accurate diagnosis and are necessary for standard of care, they present little insight into the patient experience of having a voice disorder. DESIGN Retrospective between-subject, non-experimental design. METHODS Data from 335 patients from the University of Pittsburgh Voice Center were collected from scores of the Voice Handicap Index-10 (VHI-10) and two recent questionnaires, the Voice Present Perceived Control scale (VPPC), and the Vocal Congruency Scale (VCS). Examining how these voice-specific scales related to three mental health screeners for stress (Perceived Stress Scale-4), anxiety (Generalized Anxiety Disorder-7) and depression (Patient Health Questionnaire-9) were also examined. Patient diagnoses included primary muscle tension dysphonia (pMTD), unilateral vocal fold paralysis (UVFP), vocal fold atrophy, and mid membranous vocal fold lesions. RESULTS There were significant differences in scores from the voice-specific scales between diagnostic groups with UVFP being the highest (worst) in VHI-10 and UVFP being the lowest (worst) in VCS compared to healthy controls. There was no significant difference in VPPC scores between diagnostic groups. Results showed statistically significant inverse relationships between the VHI-10 and the VPPC and between the VHI-10 and VCS for all diagnostic groups. A significant direct relationship was found between the VPPC and the VCS for patients diagnosed with MTD, UVFP and Lesions. In sum, patients with UVFP presented with the most frequent and sometimes strongest relationships between voice and mental health measures. DISCUSSION This study marks an initial investigation into the nuanced patient experience of having a voice disorder. Three theoretically unrelated voice constructs: handicap, perceived control, and sense of self, were measured via self-report. Results from this study describe the patient experience correlating to these constructs with weak correlations to stress, anxiety, and depression. Findings also clearly suggest that patient experience varies among diagnostic groups, as well as varying constructs. Measures of multiple constructs of patient perception provide valuable insight into a patient's experience of their voice disorder, guidance on the direction of voice treatment, and justification for such treatments.

Beyond the biomedical, towards the agentic: A paradigm shift for population health science. Soc Sci Med 2023; 326:115950. [PMID: 37148746 PMCID: PMC10154061 DOI: 10.1016/j.socscimed.2023.115950] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 04/02/2023] [Accepted: 05/02/2023] [Indexed: 05/08/2023]
Abstract
Life expectancy in the United States is decreasing. Health disparities are widening. Growing evidence for and integration of social and structural determinants into theory and practice has not yet improved outcomes. The COVID-19 pandemic reinforced the fact. In this paper, we argue that the biomedical model and its underlying scientific paradigm of causal determinism, which currently dominate population health, cannot meet population health needs. While criticism of the biomedical model is not new, this paper advances the field by going beyond criticism to recognize the need for a paradigm shift. In the first half of the paper, we present a critical analysis of the biomedical model and the paradigm of causal determinism. In the second half, we outline the agentic paradigm and present a structural model of health based on generalizable, group-level processes. We use the experience of the COVID-19 pandemic to illustrate the practical applications of our model. It will be important for future work to investigate the empirical and pragmatic applications of our structural model of population health.

Testing the effects of congruence in adult multilingual acquisition with implications for creole genesis. Cognition 2023; 235:105387.

Abstract
Linguists from across sub-disciplines have noted that congruence (i.e., form-function mapping) across languages in contact seems to affect acquisition and play a role in language emergence (e.g. Creole genesis). However, because congruence is often confounded with other variables (e.g., frequency, language type, speakers' proficiency levels, perceptual salience, semantic transparency), it remains unclear whether congruence per se benefits learners. In this paper, we provide an experimental test of the effects of congruence on acquisition through an artificial language-learning experiment involving English (L1) and two artificial languages (Flugerdu and Zamperese). English-speakers who identified as "native" (i.e., first-language) speakers (N = 163) were randomly assigned to one of four conditions, varying which of the three languages expressed negation with congruent forms: all three languages; only Flugerdu and Zamperese; only English and Flugerdu; or none. Our findings show that participants better acquired the negation morpheme when the form was congruent with negation in English but not when the two artificial languages alone shared a congruent form. We likewise found unanticipated spillover effects in which participants better acquired the vocabulary and grammar of the artificial languages when all three languages had congruent negation forms. These findings provide insight into the effects of congruence on language acquisition in multilingual environments and Creole language formation.

Motivated reasoning: Election integrity beliefs, outcome acceptance, and polarization before, during, and after the 2020 U.S. Presidential Election. MOTIVATION AND EMOTION 2023; 47:177-192. [PMID: 36188156 PMCID: PMC9513018 DOI: 10.1007/s11031-022-09983-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/03/2022] [Indexed: 11/25/2022]
Abstract
The 2020 U.S. Presidential Election required voters to not only form opinions of leading candidates, Donald Trump and Joe Biden, but also to make judgments about the integrity of the election itself and what-if anything-to do about it. However, partisan motivated reasoning theory (Leeper and Slothuus, Political Psychology, 35(Suppl 1): 129-156; Lodge and Taber, The rationalizing voter, Cambridge University Press, 2013) suggests judgments are often strongly influenced toward affectively desirable conclusions. Before, during, and after election projections were announced, partisan supporters of Trump and Biden rated: judgments about voter fraud and foreign interference, their acceptance of the results, and their support for recourse against the outcome (e.g., legal challenges, legislative overhauls, violence). Before the election, partisans were mildly concerned about election integrity but willing to accept the outcome without recourse. However, during vote counting, and especially after Biden was projected to be the winner, partisans dramatically changed their judgments in opposite directions, consistent with the affectively desirable conclusions relevant to each group. Biden supporters affirmed the election's integrity and accepted the results whereas Trump supporters disputed the integrity, rejected the results, and began to support recourse against the outcome. Data are consistent with partisan motivated reasoning. Discussion highlights the practical implications.

Outcomes of oblique supramalleolar osteotomy without fibular osteotomy for congruent- and incongruent-type medial ankle arthritis. Foot Ankle Surg 2022; 28:603-609. [PMID: 34226096 DOI: 10.1016/j.fas.2021.06.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/09/2021] [Accepted: 06/28/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Although high talar tilt and ankle mortise incongruence are risk factors for supramalleolar osteotomy (SMO), no study on lateral talofibular joint congruence exists. We aimed to evaluate the outcomes of oblique SMO without fibular osteotomy for medial ankle arthritis and compare them according to the lateral talofibular joint congruity. METHODS Forty-eight ankles were retrospectively reviewed and divided according to preoperative talofibular joint congruity (congruent, 22 [45.8%] vs. incongruent, 26 [54.2%]). RESULTS The mean VAS score, AOFAS score, and modified Takakura stage were significantly improved. No significant differences were noted in clinical outcomes, but the mean postoperative tibiotalar angle and difference between the upper and lower talofibular gaps were significantly different in both groups (p = 0.004 and p = 0.009, respectively). The mean Takakura stage at 1 and 2 years after surgery was higher in the incongruent group (p = 0.013, p = 0.012). CONCLUSION This procedure was effective against early- to mid-stage medial ankle arthritis. Radiographic arthritic grade changed according to the talofibular joint congruity.

What drives Taobao live streaming commerce? The role of parasocial relationships, congruence and source credibility in Chinese consumers' purchase intentions. Heliyon 2022; 8:e09676. [PMID: 35756134 PMCID: PMC9213714 DOI: 10.1016/j.heliyon.2022.e09676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 11/10/2021] [Accepted: 05/31/2022] [Indexed: 11/23/2022] Open
Abstract
The year 2021 is one of the most significant years for live streaming commerce, since numerous sectors and businesses have begun to sell their items in the form of live broadcast influence. Especially in China, Taobao live streaming often promotes an event by inviting internet celebrities to cooperate with brands to broadcast the products. For many brands, that is a very successful technique for increasing conversion rates. Researchers have lately grown interested in investigating the factors influencing the purchase decisions of Chinese consumers in the context of Taobao live streaming commerce with online celebrities. The present study is the first to theoretically combine three primarily literature-based disciplines, including source credibility, match-up hypothesis, and parasocial relationship theory, into a unified framework to bridge the research gaps. In this study, the quantitative method was employed through the use of partial least square structural equation modeling (PLS-SEM). The SmartPLS 3.0 software was applied to examine the proposed model. The data were obtained from 454 Chinese consumers who have ever purchased a cosmetic product from a famous internet celebrity on Taobao live streaming. The results indicated that the positive impact of a celebrity endorsers' perceived expertise was the powerful antecedent that affected purchase intentions, while celebrity endorsers' perceived attractiveness and trustworthiness had no significant effect. A good match-up between celebrity and product can improve the celebrity endorsers' perceived attractiveness, trustworthiness, and expertise. Moreover, it was found that the celebrity endorsers’ perceived expertise acted as a mediator of the relationship between celebrity-product congruence and purchase intentions. Finally, the findings showed that parasocial relationships have vital mediating effects on increasing purchase intentions.

Whole mitochondrial genome phylogeny of Drosophilidae. Mitochondrial DNA A DNA Mapp Seq Anal 2022; 33:1-9.

Abstract
A total of 241 mitochondrial genomes were assembled and annotated from the SRA database to reconstruct a mtDNA genome phylogeny for the genus Drosophila, the family Drosophilidae, and close relatives. The resulting mtDNA genome phylogeny is largely congruent with previous higher-level analyses of Drosophila species with the exception of the relationships between the melanogaster, montium, anannassae, saltans and obscura groups. Although relationships within these species groups are congruent between nuclear and mtDNA studies, the mtDNA genome phylogeny of the groups is different when compared to earlier studies. Monophyly of known species groups within the genus Drosophila are highly supported and, as in previous work, the genera Lordiphosa, Hirtodrosophila, Zaprionus and Scaptomya are all imbedded within the genus Drosophila. Incongruence and partitioned support analyses indicate that DNA sequences are better at resolving the phylogeny than their translated protein sequences. Such analyses also indicate that genes on the minus strand of the circular molecule (Lrrna, Srrna, ND4, ND4L and ND5) provide most of the support for the overall phylogenetic hypothesis.

Abstract
Emotional stimuli are better remembered than neutral stimuli. Music, as an emotional stimulus, modulates memory; it can change the mood and improves memory of material congruent with it (congruence hypothesis). The aim of this work is to study the effect of activating and relaxing music on emotional verbal memory in young adults, and to analyze the effect of mood congruence on the type of material remembered. 33 adults listened to a list of positive, negative and neutral words. Activating and relaxing positive music, or white noise, was used as a post-learning treatment. Mood was measured. We performed an immediate recall task. The results indicated better recall of total and negative words in free recall in subjects exposed to activating music. The activating and relaxing music generated a decrease in anxiety, while the control condition generated an increase in hostility. These results support the idea that music can be used as a treatment to modulate verbal memories, although no effect of congruence with mood was found.

Abstract
OBJECTIVES The aim of the study was to investigate and compare the preferences that citizens of four Visegrad countries hold concerning the communication between patient and provider. METHODS The patient-practitioner orientation scale was used on a general population in our research, which consists of the Sharing and Caring subscales and assesses patient-centered or doctor-centered orientation toward communication. The statistical analysis included 4000 respondents of citizens from the Czech Republic, Slovakia, Poland and Hungary. When comparing the various demographic data and the four countries with each other univariate and multivariate logistic regressions were performed. RESULTS Being female, middle aged, having a higher education and a poor health status were associated with significantly higher Sharing and Caring scores. Also, Hungarian citizens had a significantly higher Caring score compared to the other three countries. CONCLUSIONS Key demographic variables were identified that affect how citizens perceive the communication between patient and provider. With the exception of Caring among Hungarian citizens, no differences were observed among the Visegrad countries. PRACTICE IMPLICATIONS These findings have potential implications for understanding the preferences of the citizens and thus better promote a more patient-centered communication.

Abstract
PURPOSE This cross-sectional study evaluated congruence in pain assessment among Black cancer patients taking opioids for pain and their family caregivers and the effects of patient-reported depressive symptoms and cognitive complaints on the congruence. METHODS Patient-reported pain scores (current, average, and worst pain severity and pain interference) and caregiver proxy scores were independently assessed (Brief Pain Inventory). Patient-reported depressive symptoms (Patient Health Questionnaire-8) and cognitive complaints (Cognitive Difficulties Scale) were also assessed. Paired t-test, intraclass correlation coefficient (ICC), and Bland-Altman (BA) plots were used to evaluate group and dyad level congruence in pain assessment. The influence of patient depressive symptoms and cognitive complaints on congruence was examined using bivariate analyses and BA plots. RESULTS Among 50 dyads, 62% of patients and 56% of caregivers were female. Patients were older than caregivers (57 vs. 50 years, p = .008). Neither statistically significant (t-test) nor clinically relevant mean differences in pain severity and interference were found at a group level. At the dyad level, congruence was poor in pain now (ICC = 0.343) and average pain severity (ICC = 0.435), but moderate in worst pain severity (ICC = 0.694) and pain interference (ICC = 0.603). Results indicated better congruence in pain severity between patients with depressive symptoms and their caregivers, compared to patients without depressive symptoms. Patient CDS scores had no significant correlations with score differences between patients and caregivers in any pain variables. CONCLUSION Congruence varied depending on how the analysis was done. More information is needed to understand pain assessment between patients and caregivers.

Abstract
BACKGROUND Several factors may influence the validity of self-report. In this study, we aimed to assess the validity of self-reported drug use compared to urine testing among treatment-seeking patients with opioid use disorder (OUD). METHODS This cross-sectional study recruited 293 patients with OUD, referred to the Iranian National Center for Addiction Studies (INCAS) clinic, from November 2015 to June 2017. The study compared self-reported opioid use in the past 72 h with the results of urinalysis, using immunoassay technique. We estimated sensitivity, negative predictive value, percent agreement, positive percent agreement, and Cohen's kappa statistics for those with OUD. RESULTS The sensitivity of self-reported opioid use was 85.9%. Percent agreement, positive percent agreement, and Cohen's Kappa statistics between self-reported opioid use and urine testing for morphine in the first month were 88.5%, 78.1%, and 77.0, respectively. Multilevel logistic regression showed that longer treatment duration (OR = 1.21, 95%CI: 1.07-1.37, p-value = 0.002) was significantly associated with the agreement of self-reported opioid use with urine testing. CONCLUSION Self-report can be used as a reliable method for monitoring treatment adherence combined with random urine tests.

Abstract
Together with J. Paseka we introduced so-called sectionally pseudocomplemented lattices and posets and illuminated their role in algebraic constructions. We believe that-similar to relatively pseudocomplemented lattices-these structures can serve as an algebraic semantics of certain intuitionistic logics. The aim of the present paper is to define congruences and filters in these structures, derive mutual relationships between them and describe basic properties of congruences in strongly sectionally pseudocomplemented posets. For the description of filters in both sectionally pseudocomplemented lattices and posets, we use the tools introduced by A. Ursini, i.e., ideal terms and the closedness with respect to them. It seems to be of some interest that a similar machinery can be applied also for strongly sectionally pseudocomplemented posets in spite of the fact that the corresponding ideal terms are not everywhere defined.

Does taxonomic and numerical resolution affect the assessment of invertebrate community structure in New World freshwater wetlands? ECOLOGICAL INDICATORS 2021; 125:107437.

Abstract
The efficiency of biodiversity assessments and biomonitoring studies is commonly challenged by limitations in taxonomic identification and quantification approaches. In this study, we assessed the effects of different taxonomic and numerical resolutions on a range of community structure metrics in invertebrate compositional data sets from six regions distributed across North and South America. We specifically assessed the degree of similarity in the metrics (richness, equitability, beta diversity, heterogeneity in community composition and congruence) for data sets identified to a coarse resolution (usually family level) and the finest taxonomic resolution practical (usually genus level, sometimes species or morphospecies) and by presence-absence and relative abundance numerical resolutions. Spearman correlations showed highly significant and positive associations between univariate metrics (richness and equitability) calculated for coarse- and finest-resolution datasets. Procrustes analysis detected significant congruence between composition datasets. Higher correlation coefficients were found for datasets with the same numerical resolutions regardless of the taxonomic level (about 90%), while the correlations for comparisons across numerical resolutions were consistently lower. Our findings indicate that family-level resolution can be used as a surrogate of finer taxonomic resolutions to calculate a range of biodiversity metrics commonly used to describe invertebrate community structure patterns in New World freshwater wetlands without significant loss of information. However, conclusions on biodiversity patterns derived from datasets with different numerical resolutions should be critically considered in studies on wetland invertebrates.

Abstract
INTRODUCTION The Covid-19 crisis continues to profoundly impact on radiotherapy practice in the UK. We explore the views of therapeutic radiographer students on entering their first post in unique circumstances as a means to evaluate the support that may minimise negative impacts on their transition to practitioners. METHOD Focus groups were conducted outside of students' final year educational programme and immediately prior to them starting work. Qualitative data were analysed using a framework analysis. RESULTS Emergent themes from the eleven participants were: Covid-19 as a layer on top of underlying anxieties; Degree of readiness for imminent psychological, emotional and practical challenges; Feeling valued as a health professional/radiographer at this time; A mixed student and qualified staff professional identity as HCPC temporary registrants. CONCLUSION Uncertainties related to Covid-19 were seen to add a destabilising component to existing anxieties and challenges. In this context, there are significant risks of impaired professional socialisation due to incongruence between students' expectations and the reality in clinical departments. IMPLICATIONS FOR PRACTICE Informed academic support and flexible clinical preceptorship that address anxieties and congruence barriers are vital to guide new practitioners through a health crisis that presents significant challenges but also opportunity for professional development.

Congruence of cancer pain experience between patients and family caregivers and associated factors: a multicenter cross-sectional study in China. Support Care Cancer 2021; 29:5983-5990.

Abstract
PURPOSE The purposes of this study were to determine whether there were differences in the cancer pain experience between patients and family caregivers (FCGs) and to explore the associated factors that influence cancer pain experience congruence. METHODS A multicenter cross-sectional study was conducted. A total of 410 patient-family caregiver dyads completed face-to-face surveys, including information about basic characteristics, the Patient Pain Questionnaire (PPQ), and the Family Pain Questionnaire (FPQ). The difference in cancer pain experience between patients and family caregivers was analyzed using a paired t test. Indicators for the congruence of cancer pain experience were analyzed using the chi-square test and two independent-sample t tests for bivariate analysis and multivariate binary logistic regression analysis. RESULTS Of the patients, 57.1% were men, and 60.7% perceived moderate performance status. The majority of the family caregivers was female (54.9%). The mean (SD) score on the pain experience subscale was 4.82 (1.66) for 410 patients and 5.02 (1.66) for 410 family caregivers. The difference was significant (P < 0.01). Additionally, 87 (21.2%) dyads were in the congruent group, and 323 (78.8%) dyads were in the incongruent group. Patients' self-perceived moderate performance status (OR = 2.983, P < 0.01) and family caregivers' pain knowledge (OR = 1.171, P < 0.05) were the main factors influencing the congruence of cancer pain experience. CONCLUSION The findings of this study indicate that family caregivers reported significantly worse cancer pain experiences than patients. Family caregivers' pain knowledge was a primary influencing factor. It is suggested that educational interventions aimed at teaching family caregivers and patients how to communicate their pain experience and improving the knowledge of family members regarding pain and its management may help in aligning their perceptions and thereby contribute to better quality of life and pain management outcomes.

A multisite, assessor-blinded, intent-to-treat, parallel-group, randomized controlled clinical trial in five hospital-based HIV clinics enrolled 449 participants aged 22 to 77 years during October 2013-March 2017. Patients living with HIV/family dyads were randomized at 2:1 ratio to 2 weekly ~ 60-min sessions either ACP (n = 155 dyads)-(1) ACP facilitated conversation, (2) Advance directive completion; or Control (n = 68 dyads)-(1) Developmental/relationship history, (2) Nutrition/exercise tips. ACP families/surrogates were more likely to accurately report patients' treatment preferences at Time 1 (T1) and 12 months post-intervention (T2) compared to controls, experiencing high congruence longitudinally (high→high transition), [63·6% vs 37·7% (difference = 25·9%, 95% CI: 11·3%, 40·4%, χ2 = 11·52, p = 0·01)], even as patients' preferences changed over time. ACP families/surrogates had eight times the odds of controls of having an excellent understanding of patients' treatment preferences (Adjusted Odds Ratio 7.91, 95%CI: 3.08, 20.3). Conversations matter.

Polarities influence implicit associations between colour and emotion. Acta Psychol (Amst) 2020; 209:103143. [PMID: 32731010 DOI: 10.1016/j.actpsy.2020.103143] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 05/26/2020] [Accepted: 07/15/2020] [Indexed: 10/23/2022] Open
Abstract
Colours are linked to emotional concepts. Research on the effect of red in particular has been extensive, and evidence shows that positive as well as negative associations can be salient in different contexts. In this paper, we investigate the impact of the contextual factor of polarity. According to the polarity-correspondence principle, negative and positive category poles are assigned to the binary response categories (here positive vs. negative valence) and the perceptual dimension (green vs. red) in a discrimination task. Response facilitation occurs only where the conceptual category (valence) and the perceptual feature (colour) share the same pole (i.e., where both are plus or both are minus). We asked participants (n = 140) to classify the valence of green and red words within two types of blocks: (a) where all words were of the same colour (monochromatic conditions) providing no opposition in the perceptual dimension, and (b) where red and green words were randomly mixed (mixed-colour conditions). Our results show that red facilitates responses to negative words when the colour green is present (mixed-colour conditions) but not when it is absent (monochromatic conditions). This is in line with the polarity-correspondence principle, but colour-specific valence-affect associations contribute to the found effects.

Mindful medical practice: An innovative core course to prepare medical students for clerkship. PERSPECTIVES ON MEDICAL EDUCATION 2020; 9:256-259. [PMID: 32504447 PMCID: PMC7459040 DOI: 10.1007/s40037-020-00591-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
BACKGROUND Medical students show a decline in empathy and ethical reasoning during medical school that is most marked during clerkship. We believe that part of the problem is that students do not have the skills and ways of being and relating necessary to deal effectively with the overwhelming clinical experience of clerkship. APPROACH At McGill University in Montreal, starting in January 2015, we have taught a course on mindful medical practice that combines a clinical focus on the combination of mindfulness and congruent relating that is aimed at giving students the skills and ways of being to function effectively in clerkship. The course is taught to all medical students in groups of 20, weekly for 7 weeks, in the 6 months immediately prior to clerkship, a time when students are very open to learning the skills they need to take effective care of patients. EVALUATION The course has been well accepted by students as evidenced by their engagement, their evaluations, and their comments in the essays that they write at the end of the course. In a follow-up session at the simulation centre one year later students remember clearly and enact what they were taught in the course. REFLECTION The next steps will be to conduct a formal evaluation of the effect of our teaching that will involve a combination of qualitative methods to clarify the nature of the impact on our students and a quantitative assessment of the difference the course makes to students' experience and performance in clerkship.

Congruence between Meshes and Library Files of Implant Scanbodies: An In Vitro Study Comparing Five Intraoral Scanners. J Clin Med 2020; 9:jcm9072174.

Abstract
Purpose. To compare the reliability of five different intraoral scanners (IOSs) in the capture of implant scanbodies (SBs) and to verify the dimensional congruence between the meshes (MEs) of the SBs and the corresponding library file (LF). Methods. A gypsum cast of a fully edentulous maxilla with six implant analogues and SBs screwed on was scanned with five different IOSs (PRIMESCAN®, CS 3700®, MEDIT i-500®, ITERO ELEMENTS 5D®, and Emerald S®). Ten scans were taken for each IOS. The resulting MEs were imported to reverse engineering software for 3D analysis, consisting of the superimposition of the SB LF onto each SB ME. Then, a quantitative and qualitative evaluation of the deviations between MEs and LF was performed. A careful statistical analysis was performed. Results. PRIMESCAN® showed the highest congruence between SB MEs and LF, with the lowest mean absolute deviation (25.5 ± 5.0 μm), immediately followed by CS 3700® (27.0 ± 4.3 μm); the difference between them was not significant (p = 0.1235). PRIMESCAN® showed a significantly higher congruence than MEDIT i-500® (29.8 ± 4.8 μm, p < 0.0001), ITERO ELEMENTS 5D® (34.2 ± 9.3 μm, p < 0.0001), and Emerald S® (38.3 ± 7.8 μm, p < 0.0001). CS 3700® had a significantly higher congruence than MEDIT i-500® (p = 0.0004), ITERO ELEMENTS 5D® (p < 0.0001), and Emerald S® (p < 0.0001). Significant differences were also found between MEDIT i-500® and ITERO ELEMENTS 5D® (p < 0.0001), MEDIT i-500® and Emerald S® (p < 0.0001), and ITERO ELEMENTS 5D® and Emerald S® (p < 0.0001). Significant differences were found among different SBs when scanned with the same IOS. The deviations of the IOSs showed different directions and patterns. With PRIMESCAN®, ITERO ELEMENTS 5D®, and Emerald S®, the MEs were included inside the LF; with CS 3700®, the LF was included in the MEs. MEDIT i-500® showed interpolation between the MEs and LF, with no clear direction for the deviation. Conclusions. Statistically different levels of congruence were found between the SB MEs and the corresponding LF when using different IOSs. Significant differences were also found between different SBs when scanned with the same IOS. Finally, the qualitative evaluation revealed different directions and patterns for the five IOSs.

Biodiversity patterns across taxonomic groups along a lake water-depth gradient: Effects of abiotic and biotic drivers. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 686:1262-1271. [PMID: 31412522 DOI: 10.1016/j.scitotenv.2019.05.381] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 05/24/2019] [Accepted: 05/24/2019] [Indexed: 06/10/2023]
Abstract
Understanding biodiversity patterns and the role of biotic attributes in governing these patterns remains one of the most important challenges in ecology. Here, taking water depth in Lake Lugu as a typical geographical gradient, we studied how these different taxa, that is bacteria, diatoms and chironomids, respond to the water depth and environmental gradients using molecular and morphological methods. We further evaluated the relative importance of water depth, environmental variables and biotic attributes in explaining biological characteristics, such as biomass, species richness, and community composition. The biomass of chironomids and the richness of bacteria and chironomids showed a nonlinearly decreasing pattern associated with increased water depth, while biomass and species richness of diatoms showed U-shaped and hump-shaped patterns, respectively. The three taxonomic groups all showed increasing dissimilarity with water depth changes, and there was clear cross-taxon congruence among the variations in community composition. Abiotic variables were pivotal in structuring biological characteristics; however, the biotic attributes also explained a unique portion of their variations. This suggests that biotic interactions significantly influenced the patterns of biomass, species richness, and community compositions along the water depth gradient for the three taxonomic groups studied. Our results provide new evidence that biotic attributes could help in predicting the biodiversity of aquatic communities along geographical gradients, such as water depth.

Abstract
AIMS The aim of this study was to determine and compare the congruency of the articular surface contact area of the patellofemoral joint (PFJ) during both active and passive movement of the knee with the use of an MRI mapping technique in both the stable and unstable PFJ. PATIENTS AND METHODS A prospective case-control MRI imaging study of patients with a history of PFJ instability and a control group of volunteers without knee symptoms was performed. The PFJs were imaged with the use of an MRI scan during both passive and active movement from 0° through to 40° of flexion. The congruency through measurement of the contact surface area was mapped in 5-mm intervals on axial slices. In all, 40 patients were studied. The case group included 31 patients with symptomatic patellofemoral instability and the control group of nine asymptomatic volunteers. The ages were well matched between the case and control groups. The mean age was 25 years (16 to 42; sd 6.9) in the case group and 26 years (19 to 32; sd 5.1) in the control group. There were 19 female and 12 male patients in the case group. RESULTS The unstable PFJs were demonstrably less congruent than the stable PFJs throughout the range of knee movement. The greatest mean differences in congruency between unstable and stable PFJ's were observed between 11° and 20° flexion (1.73 cm2 vs 4.00 cm2; p < 0.005). CONCLUSION The unstable PFJ is less congruent than the stable PFJ throughout the range of knee movement studied. This approach to mapping PFJ congruency produces a measurable outcome and will allow the assessment of pre- and postoperative results following surgical intervention. This may facilitate the design of new procedures for patients with PFJ instability. If a single axial series is to be obtained on MRI scan, the authors recommend 11° to 20° of tibiofemoral flexion, as this was shown to have the greatest difference in contact surface area between the case and control groups.

Abstract
Sporting events can be announced using sports posters and by disseminating advertisements on the internet, on the street and in print media. But until now, no prior research has measured the effectiveness of sponsorship in sporting event posters. This study uses eye tracking to measure the effectiveness of sporting event posters and proposes considering the level of the viewer's attention as an indicator. This research involves a factorial experiment based on the following variables: congruence, the number of sponsors, and placement of the sponsor's advertisement in a sporting event poster. The results indicate that sponsors positioned in the poster's area of action receive more attention. However, we were unable to prove that congruent sponsors receive more attention, as claimed in the literature. This result could be due to a situation of blindness towards the sponsor. The conclusion section of this paper discusses theoretical conclusions and potential managerial actions.

Species turnover in plants does not predict turnover in flower-visiting insects. PeerJ 2019; 6:e6139.

Abstract
Congruence between plant and insect diversity is considered possibly useful in conservation planning, as the better known plants could be surrogates for the lesser known insects. There has been little quantification of congruence across space, especially in biodiversity rich areas. We compare here species richness, and turnover relationships between plants and flower-visiting insects across space (0.5-80 km) in natural areas of a biodiversity hotspot, the Greater Cape Floristic Region, South Africa. A total of 22,352 anthophile individuals in 198 species and 348 plant species were sampled. A comparison between the plants and anthophiles suggest significant concordance between the two assemblages. However, turnover was weaker in plants than in anthophiles. Plant turnover decreased with greater geographical distance between plot pairs. In contrast, insect turnover remained high with increasing geographical distance between plot pairs. These findings suggest that while patterns of plant diversity and distribution shape flower-visiting insect assemblages, they are not reliable surrogates. The conservation significance of these results is that specialist mutualisms are at greatest risk, and that set-asides on farms would help improve the functional connectivity leading to the maintenance of the full range of mutualisms.

Do Reports on Personal Preferences of Persons with Dementia Predict Their Responses to Group Activities? Dement Geriatr Cogn Disord 2018; 46:100-108.

Abstract
BACKGROUND We examine the utility of individualizing activities for persons with dementia (PwD) on the basis of congruence with preferences. Previous studies demonstrated only limited evidence of individualization of activity content to improve response, tended not to consider group activities, or were inconclusive. METHODS Participants were 90 PwD residing in a nursing home or attending a day center. After family and staff caregivers rated preferences for music, exercise, reading, brain games, and baking, group activities were conducted, and the impact on mood and engagement was monitored. We tested whether participants showed more engagement and better mood when group activities were related to topics they liked, in comparison to topics they did not like (within-person analysis), and whether persons who liked certain topics showed better outcomes in comparison to persons who did not like those topics (between-person analyses). RESULTS Within-person analysis found a relationship between the report of liking the topic and engagement and mood during the group activity, confirming the benefit of individualizing activities to persons' preferences. Between-person analyses were statistically significant only when based on staff preference ratings. CONCLUSION Despite the fact that each topic represents a wide range of possible activities, individualizing group activities based on participants' preferences can optimize the impact.

Novel Approaches for Phylogenetic Inference from Morphological Data and Total-Evidence Dating in Squamate Reptiles (Lizards, Snakes, and Amphisbaenians). Syst Biol 2018; 66:38-56. [PMID: 28173602 DOI: 10.1093/sysbio/syw068] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2015] [Revised: 07/12/2016] [Accepted: 07/20/2016] [Indexed: 02/04/2023] Open
Abstract
Here, I combine previously underutilized models and priors to perform more biologically realistic phylogenetic inference from morphological data, with an example from squamate reptiles. When coding morphological characters, it is often possible to denote ordered states with explicit reference to observed or hypothetical ancestral conditions. Using this logic, we can integrate across character-state labels and estimate meaningful rates of forward and backward transitions from plesiomorphy to apomorphy. I refer to this approach as MkA, for “asymmetric.” The MkA model incorporates the biological reality of limited reversal for many phylogenetically informative characters, and significantly increases likelihoods in the empirical data sets. Despite this, the phylogeny of Squamata remains contentious. Total-evidence analyses using combined morphological and molecular data and the MkA approach tend toward recent consensus estimates supporting a nested Iguania. However, support for this topology is not unambiguous across data sets or analyses, and no mechanism has been proposed to explain the widespread incongruence between partitions, or the hidden support for various topologies in those partitions. Furthermore, different morphological data sets produced by different authors contain both different characters and different states for the same or similar characters, resulting in drastically different placements for many important fossil lineages. Effort is needed to standardize ontology for morphology, resolve incongruence, and estimate a robust phylogeny. The MkA approach provides a preliminary avenue for investigating morphological evolution while accounting for temporal evidence and asymmetry in character-state changes.

Audio-visual interaction in visual motion detection: Synchrony versus Asynchrony. JOURNAL OF OPTOMETRY 2017; 10:242-251.

Abstract
OBJECTIVE Detection and identification of moving targets is of paramount importance in everyday life, even if it is not widely tested in optometric practice, mostly for technical reasons. There are clear indications in the literature that in perception of moving targets, vision and hearing interact, for example in noisy surrounds and in understanding speech. The main aim of visual perception, the ability that optometry aims to optimize, is the identification of objects, from everyday objects to letters, but also the spatial orientation of subjects in natural surrounds. To subserve this aim, corresponding visual and acoustic features from the rich spectrum of signals supplied by natural environments have to be combined. METHODS Here, we investigated the influence of an auditory motion stimulus on visual motion detection, both with a concrete (left/right movement) and an abstract auditory motion (increase/decrease of pitch). RESULTS We found that incongruent audiovisual stimuli led to significantly inferior detection compared to the visual only condition. Additionally, detection was significantly better in abstract congruent than incongruent trials. For the concrete stimuli the detection threshold was significantly better in asynchronous audiovisual conditions than in the unimodal visual condition. CONCLUSION We find a clear but complex pattern of partly synergistic and partly inhibitory audio-visual interactions. It seems that asynchrony plays only a positive role in audiovisual motion while incongruence mostly disturbs in simultaneous abstract configurations but not in concrete configurations. As in speech perception in hearing-impaired patients, patients suffering from visual deficits should be able to benefit from acoustic information.

Abstract
Impaired analysis of signal conflict and congruence may contribute to diverse socio-emotional symptoms in frontotemporal dementias, however the underlying mechanisms have not been defined. Here we addressed this issue in patients with behavioural variant frontotemporal dementia (bvFTD; n = 19) and semantic dementia (SD; n = 10) relative to healthy older individuals (n = 20). We created auditory scenes in which semantic and emotional congruity of constituent sounds were independently probed; associated tasks controlled for auditory perceptual similarity, scene parsing and semantic competence. Neuroanatomical correlates of auditory congruity processing were assessed using voxel-based morphometry. Relative to healthy controls, both the bvFTD and SD groups had impaired semantic and emotional congruity processing (after taking auditory control task performance into account) and reduced affective integration of sounds into scenes. Grey matter correlates of auditory semantic congruity processing were identified in distributed regions encompassing prefrontal, parieto-temporal and insular areas and correlates of auditory emotional congruity in partly overlapping temporal, insular and striatal regions. Our findings suggest that decoding of auditory signal relatedness may probe a generic cognitive mechanism and neural architecture underpinning frontotemporal dementia syndromes.

Pregnancy termination for fetal abnormality: are health professionals' perceptions of women's coping congruent with women's accounts? BMC Pregnancy Childbirth 2017; 17:60.

Abstract
Background Pregnancy termination for fetal abnormality (TFA) may have profound psychological consequences for those involved. Evidence suggests that women’s experience of care influences their psychological adjustment to TFA and that they greatly value compassionate healthcare. Caring for women in these circumstances presents challenges for health professionals, which may relate to their understanding of women’s experience. This qualitative study examined health professionals’ perceptions of women’s coping with TFA and assessed to what extent these perceptions are congruent with women’s accounts. Methods Fifteen semi-structured interviews were carried out with health professionals in three hospitals in England. Data were analysed using thematic analysis and compared with women’s accounts of their own coping processes to identify similarities and differences. Results Health professionals’ perceptions of women’s coping processes were congruent with women’s accounts in identifying the roles of support, acceptance, problem-solving, avoidance, another pregnancy and meaning attribution as key coping strategies. Health professionals regarded coping with TFA as a unique grieving process and were cognisant of women’s idiosyncrasies in coping. They also considered their role as information providers as essential in helping women cope with TFA. The findings also indicate that health professionals lacked insight into women’s long-term coping processes and the potential for positive growth following TFA, which is consistent with a lack of aftercare following TFA reported by women. Conclusions Health professionals’ perceptions of women’s coping with TFA closely matched women’s accounts, suggesting a high level of understanding. However, the lack of insight into women’s long-term coping processes has important clinical implications, as research suggests that coping with TFA is a long-term process and that the provision of aftercare is beneficial to women. Together, these findings call for further research into the most appropriate ways to support women post-TFA, with a view to developing a psychological intervention to better support women in the future.

Abstract
Van Hooft and Born (Journal of Applied Psychology 97:301-316, 2012) presented data challenging both the correctness of a congruence model of faking on personality test items and the relative merit (i.e., effect size) of response latencies for identifying fakers. We suggest that their analysis of response times was suboptimal, and that it followed neither from a congruence model of faking nor from published protocols on appropriately filtering the noise in personality test item answering times. Using new data and following recommended analytic procedures, we confirmed the relative utility of response times for identifying personality test fakers, and our obtained results, again, reinforce a congruence model of faking.

Abstract
BACKGROUND Osteoarthritic progression of the lateral compartment remains a leading indication for medial unicompartmental knee arthroplasty (UKA) revision. Therefore, the purpose of this study was to evaluate the alterations of the lateral compartment congruence and joint space width (JSW) following medial UKA. METHODS Retrospectively, lateral compartment congruence and JSW were evaluated in 174 knees (74 females, 85 males, mean age 65.5years; SD±10.1) preoperatively and six weeks postoperatively, and compared to 41 healthy knees (26 men, 15 women, mean age 33.7years; SD±6.4). Congruence (CI) was calculated using validated software that evaluates the geometric relationship between surfaces and calculates a congruence index (CI). JSW was measured on three sides (inner, middle, outer) by subdividing the lateral compartment into four quarters. RESULTS The CI of the control group was 0.98 (SD±0.01). The preoperative CI was 0.88 (SD±0.01), which improved significantly to 0.93 (SD±0.03) postoperatively (p<0.001). In 82% of knees, CI improved after surgery, while in 18% it decreased. The preoperative significant JSW differences of the inner (p<0.001) and outer JSW (p<0.001) were absent postoperatively. CONCLUSION Our data suggests that a well-conducted medial UKA not only resurfaces the medial compartment but also improves congruence and restores the JSW of the lateral compartment.

Abstract
Longitudinal patterns of identity formation were analyzed in a representative cohort group of Finnish men and women born in 1959 across ages 27, 36, 42, and 50. The data were drawn from the Jyväskylä Longitudinal Study of Personality. Identity status (diffused, moratorium, foreclosed, achieved) from all four ages was available for 172 participants (54% females). Marcia's Identity Status Interview used in this research included five domains: religious beliefs, political identity, occupational career, intimate relationships, and lifestyle. The findings indicated great variability in identity status across domains at each age level, and the identity trajectories fluctuated from age 27 to 50. The developmental trend from age 27 to 50 was moderately progressive (toward achievement) for the five domains and for overall identity, with the exception of a slightly regressive trend in male religious identity. Remaining stable in the same status category across the four measurements was rare and emerged only for diffusion in the ideological domains. Women generally outnumbered men in identity achievement at earlier ages, but the gender differences diminished in most domains at age 50, except in religious identity. In women overall diffusion decreased over time, but in men it remained at about 20% at ages 42 and 50.

Abstract
Youth with perinatally-acquired HIV infection (PHIV) routinely survive into adulthood requiring transition to adult care. Research underscores the importance of assessing transition perspective congruence between adolescents and guardians. Interviews focused on transition decisions were conducted with 18 adolescents with PHIV and their guardians recruited from a southeastern US pediatric infectious disease clinic. Transcribed responses were coded as congruent or divergent. Adolescents and guardians held congruent views that the transition process had not started. Fewer dyads agreed upon the level of adolescent and guardian involvement in transition decisions. Providers should assess congruence of adolescent and guardian perspectives regarding transition-related decisions.

Abstract
Comparative genomics based on whole genome sequencing (WGS) is increasingly being applied to investigate questions within evolutionary and molecular biology, as well as questions concerning public health (e.g., pathogen outbreaks). Given the impact that conclusions derived from such analyses may have, we have evaluated the robustness of clustering individuals based on WGS data to three key factors: (1) next-generation sequencing (NGS) platform (HiSeq, MiSeq, IonTorrent, 454, and SOLiD), (2) algorithms used to construct a SNP (single nucleotide polymorphism) matrix (reference-based and reference-free), and (3) phylogenetic inference method (FastTreeMP, GARLI, and RAxML). We carried out these analyses on 194 whole genome sequences representing 107 unique Salmonella enterica subsp. enterica ser. Montevideo strains. Reference-based approaches for identifying SNPs produced trees that were significantly more similar to one another than those produced under the reference-free approach. Topologies inferred using a core matrix (i.e., no missing data) were significantly more discordant than those inferred using a non-core matrix that allows for some missing data. However, allowing for too much missing data likely results in a high false discovery rate of SNPs. When analyzing the same SNP matrix, we observed that the more thorough inference methods implemented in GARLI and RAxML produced more similar topologies than FastTreeMP. Our results also confirm that reproducibility varies among NGS platforms where the MiSeq had the lowest number of pairwise differences among replicate runs. Our investigation into the robustness of clustering patterns illustrates the importance of carefully considering how data from different platforms are combined and analyzed. We found clear differences in the topologies inferred, and certain methods performed significantly better than others for discriminating between the highly clonal organisms investigated here. The methods supported by our results represent a preliminary set of guidelines and a step towards developing validated standards for clustering based on whole genome sequence data.

The rubber hand illusion depends on a congruent mapping between real and artificial fingers. Acta Psychol (Amst) 2014; 152:34-41. [PMID: 25103418 DOI: 10.1016/j.actpsy.2014.07.012] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2013] [Revised: 07/16/2014] [Accepted: 07/18/2014] [Indexed: 12/01/2022] Open
Abstract
The rubber hand illusion (RHI), in which a visible artificial hand is touched (or moves) synchronously with the participant's unseen own hand, indicates that body representations can undergo rapid changes. While several constraints for this illusion have been described, some reports highlight a remarkable flexibility of body representations, even contradicting a priori assumptions regarding body appearance and anatomy (e.g., the subjective embodiment of a third arm). Here we examine the impact of congruence between touches at (or movements of) the real and the artificial hand, as well as the role of predictability of touches (or movements). We implemented two versions of the RHI paradigm, based on passive tactile stimulation and active voluntary movements. The results show that (a) predictability does not modulate perceived embodiment, and that (b) congruent mapping between real and artificial fingers is a necessary condition for both the tactile and the motor RHI. Together with previously reported constraints for bodily illusions, these results are reduced to four principles, which determine subjective embodiment: temporal synchrony, congruence of mapping between real and artificial body parts, body unity and body shape.

Student nurses' views on respect towards service users - an interpretative phenomenological study. NURSE EDUCATION TODAY 2014; 34:474-479. [PMID: 23806192 DOI: 10.1016/j.nedt.2013.05.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2013] [Revised: 05/07/2013] [Accepted: 05/20/2013] [Indexed: 06/02/2023]
Abstract
AIM To explore student nurses' understanding and behaviours of respect towards patients in order to inform educational strategies to optimise respectful care. BACKGROUND There is a causal relationship between the perception of being treated with respect and patient satisfaction. Concerns over standards of care prompted a commissioned report into the quality of nurse education in the United Kingdom. DESIGN A hermeneutic phenomenological interview study was used to identify and interpret student nurses' behaviours and understanding of respect towards patients. SETTING University health and social care faculty in the north-west of England, United Kingdom. PARTICIPANTS Eight third-year student nurses (adult branch), on different university sites, with practice placements across different healthcare trusts. METHODS Interviews about their understanding of respect and their behavioural intentions of respect towards patients were recorded and transcribed, then analysed using interpretative phenomenological analysis (IPA) to produce themes from the data. FINDINGS Three themes of relevance to nurse education were identified. Respect is a complex concept that is difficult to apply in practice. Students are not always aware of incongruence between their feelings of respect towards patients and their behaviours towards them. Role-modelling of respectful care is variable, and essential care is often learned from healthcare assistants. DISCUSSION Awareness of emotional responses and their relationship to patient perceptions of respect should be facilitated in theory and practice. Rehearsal of the application of respect involving emotional labour, and reflection in and on the practice of respectful care, are needed to address student learning needs. The theory-practice gap in relation to respect, variation in professional practice and the under-recognised importance of healthcare assistants in student nurse education, are barriers to the learning of respect to patients. CONCLUSIONS Interactive education experiences are important to develop self-awareness and insight into respectful care. Mentorship in practice should encourage reflection in and on the practice of respect towards patients.

Global patterns of freshwater species diversity, threat and endemism. GLOBAL ECOLOGY AND BIOGEOGRAPHY : A JOURNAL OF MACROECOLOGY 2014; 23:40-51.

Abstract
AIM Global-scale studies are required to identify broad-scale patterns in the distributions of species, to evaluate the processes that determine diversity and to determine how similar or different these patterns and processes are among different groups of freshwater species. Broad-scale patterns of spatial variation in species distribution are central to many fundamental questions in macroecology and conservation biology. We aimed to evaluate how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species. LOCATION Global. METHODS We compiled geographical range data on 7083 freshwater species of mammals, amphibians, reptiles, fishes, crabs and crayfish to evaluate how species richness, richness of threatened species and endemism are distributed across freshwater ecosystems. We evaluated how congruent these measures of diversity were among taxa at a global level for a grid cell size of just under 1°. RESULTS We showed that although the risk of extinction faced by freshwater decapods is quite similar to that of freshwater vertebrates, there is a distinct lack of spatial congruence in geographical range between different taxonomic groups at this spatial scale, and a lack of congruence among three commonly used metrics of biodiversity. The risk of extinction for freshwater species was consistently higher than for their terrestrial counterparts. MAIN CONCLUSIONS We demonstrate that broad-scale patterns of species richness, threatened-species richness and endemism lack congruence among the six freshwater taxonomic groups examined. Invertebrate species are seldom taken into account in conservation planning. Our study suggests that both the metric of biodiversity and the identity of the taxa on which conservation decisions are based require careful consideration. As geographical range information becomes available for further sets of species, further testing will be warranted into the extent to which geographical variation in the richness of these six freshwater groups reflects broader patterns of biodiversity in fresh water.

Incongruent object/context relationships in visual scenes: where are they processed in the brain? Brain Cogn 2013; 84:34-43. [PMID: 24280445 DOI: 10.1016/j.bandc.2013.10.008] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2013] [Revised: 10/25/2013] [Accepted: 10/28/2013] [Indexed: 11/18/2022]
Abstract
Rapid object visual categorization in briefly flashed natural scenes is influenced by the surrounding context. The neural correlates underlying reduced categorization performance in response to incongruent object/context associations remain unclear and were investigated in the present study using fMRI. Participants were instructed to categorize objects in briefly presented scenes (exposure duration=100ms). Half of the scenes consisted of objects pasted in an expected (congruent) context, whereas for the other half, objects were embedded in incongruent contexts. Object categorization was more accurate and faster in congruent relative to incongruent scenes. Moreover, we found that the two types of scenes elicited different patterns of cerebral activation. In particular, the processing of incongruent scenes induced increased activations in the parahippocampal cortex, as well as in the right frontal cortex. This higher activity may indicate additional neural processing of the novel (non experienced) contextual associations that were inherent to the incongruent scenes. Moreover, our results suggest that the locus of object categorization impairment due to contextual incongruence is in the right anterior parahippocampal cortex. Indeed in this region activity was correlated with the reaction time increase observed with incongruent scenes. Representations for associations between objects and their usual context of appearance might be encoded in the right anterior parahippocampal cortex.
