Quantum projections on conceptual subspaces: A deeper dive into methodological challenges and opportunities

In alignment with the distributional hypothesis of language, the work "Quantum Projections on Conceptual Subspaces" (Martínez-Mingo A, Jorge-Botana G, Martinez-Huertas JÁ, et al. Quantum projections on conceptual subspaces. Cogn Syst Res 2023; 82: 101154) proposed a methodology for generating conceptual subspaces from textual information based on previous work (Martinez-Mingo A, Jorge-Botana G and Olmos R. Quantum approach for similarity evaluation in LSA vector space models. 2020). These subspaces enable the utilization of the quantum model of similarity put forth by Pothos and Busemeyer (Pothos E, Busemeyer J. A quantum probability explanation for violations of symmetry in similarity judgments. In Proceedings of the annual meeting of the cognitive science society, 2011, Vol. 33, No. 33), allowing for the empirical examination of the violations of assumptions concerning symmetry and triangular inequality (Tversky A. Features of similarity. Psychol Rev 1977; 84: 327-352; Yearsley JM, Barque-Duran A, Scerrati E, et al. The triangle inequality constraint in similarity judgments. Prog Biophys Mol Biol 2017; 130: 26-32), as well as the diagnosticity effect (Tversky A. Features of similarity. Psychol Rev 1977; 84: 327-352; Yearsley JM, Pothos EM, Barque-Duran A, et al. Context effects in similarity judgments. J Exp Psychol Gen 2022; 151: 711-717), within a data-driven environment. These psychological biases, deeply studied by authors such as Tversky and Kahneman, inform us about the limitations of modeling psychological similarity measures using tools from classical geometry. This commentary aims to offer methodological clarifications, discuss theoretical and practical implications, and speculate on future directions in this field of research. Concretely, it aims to propose the use of different contours (conceptual or contextual) to generate the subspaces, which lead to subspaces of terms or contexts. Once these contours are defined, a differentiation is proposed between Aggregated Terms Subspaces (ATSs), Aggregated Contexts Subspaces (ACSs), and Aggregated Features Subspaces (AFSs) depending on whether we define the subspaces by grouping the terms or contexts within the contour, or from the latent dimensions of the semantic space obtained in the contour window. Finally, new data is provided on the violation of the triangular inequality assumption through the application of the quantum similarity model to ATSs.

Are valence and arousal related to the development of amodal representations of words? A computational study

In this study, we analyzed the relationship between the amodal (semantic) development of words and two popular emotional norms (emotional valence and arousal) in English and Spanish languages. To do so, we combined the strengths of semantics from vector space models (vector length, semantic diversity, and word maturity measures), and feature-based models of emotions. First, we generated a common vector space representing the meaning of words at different developmental stages (five and four developmental stages for English and Spanish, respectively) using the Word Maturity methodology to align different vector spaces. Second, we analyzed the amodal development of words through mixed-effects models with crossed random effects for words and variables using a continuous time metric. Third, the emotional norms were included as covariates in the statistical models. We evaluated more than 23,000 words, whose emotional norms were available for more than 10,000 words, in each language separately. Results showed a curve of amodal development with an increasing linear effect and a small quadratic deceleration. A relevant influence on the amodal development of words was found only for emotional valence (not for arousal), suggesting that positive words have an earlier amodal development and a less pronounced semantic change across early lifespan.

Detection of blaCTX-M-15 in an integrative and conjugative element in four extensively drug-resistant Haemophilus parainfluenzae strains causing urethritis

Haemophilus parainfluenzae is a commensal organism with rising numbers of multidrug-resistant (MDR) strains. This pathogen is of increasing clinical relevance in urogenital infection. The aim of this work was to identify and characterise the molecular mechanisms of resistance associated with four cephalosporin-resistant H. parainfluenzae strains collected from patients with urethritis. Antimicrobial resistance was determined by microdilution following European Committee on Antimicrobial Susceptibility Testing criteria. Strains were then analysed by whole-genome sequencing to determine clonal relationship and the molecular basis of antimicrobial resistance. Finally, a phylogenetic analysis was performed on all urogenital MDR strains of H. parainfluenzae previously isolated in our hospital. All strains were resistant to β-lactams, macrolides, tetracycline, fluoroquinolones, chloramphenicol, cotrimoxazole, and aminoglycosides. The resistance profile was compatible with the presence of an extended-spectrum β-lactamase (ESBL). Whole-genome sequencing detected blaCTX-M-15 that conferred high minimum inhibitory concentrations to cephalosporins in two novel integrative and conjugative elements (ICEHpaHUB6 and ICEHpaHUB7) that also harboured a blaTEM-1 β-lactamase. This study shows a novel blaCTX-M-15 ESBL carried in an integrative conjugative element in four extensively drug-resistant H. parainfluenzae strains. This resistance determinant could be transmitted to other sexually transmitted pathogens and this is a cause for concern.

A mixed methods study using case studies prepared by nursing students as a clinical practice evaluation tool

AIM

To identify the presence of variability in the evaluation of case studies prepared by nursing students during their primary care rotations based on the existing evaluation rubric. To explore the difficulties experienced by link lecturers and students in preparing and evaluating case studies.

DESIGN

A mixed methods study.

METHODS

The scores for the rubric items and the final grades for the case studies were collected from a sample of 132 cases. Qualitative information was collected by conducting open-ended interviews with lecturers and a focus group session with students.

RESULTS

Statistically significant differences were identified between the lecturers' mean final grades [F(5.136) = 3.984, p = 0.002] and a variety of items in the evaluation rubric (p < 0.05). In addition, effect sizes [η2 (≈0.14)] of considerable magnitude were found. Two themes emerged from the qualitative data: (1). the challenge of preparing the case studies and (2). the variable nature of the evaluations.

Intimate partner violence among adolescents: Prevalence rates after one decade of research

INTRODUCTION

Intimate partner violence research and intervention strategies have grown substantially over the last two decades. However, little research has examined whether the intimate partner prevalence has changed or remained stable over time in Spain. Moreover, few studies have analyzed whether intimate partner violence prevalence rates among genders and age groups have fluctuated similarly or not.

METHOD

The aim of this study was to analyze the trends observed in intimate partner violence perpetration and victimization rates among adolescents in three sample cohorts from Spain interviewed in 2006, 2010, and 2016 (4591 Spanish adolescents; 53.6% girls and 46.2% boys). ANCOVA was used to compare the population means between the cohorts: sex, age, and the type of intimate partner violence, for example, verbal, physical, and sexual.

RESULTS

The results showed a significant decrease in intimate partner violence rates from 2006 to 2016, which was more noticeable within the first half of this decade. Throughout the decade, the girls perpetrated more verbal and mild physical assaults, while the boys perpetrated more sexual assaults. However, these results suggest a clear bidirectional intimate partner violence dynamic between the genders. Additionally, late adolescence reported a higher prevalence of aggressions.

CONCLUSIONS

The results highlight the need to adapt current prevention strategies considering the differences in the intimate partner violence trajectories based on sex and age, with the aim of regaining the marked rate of decline in aggression observed up to 2010.

Recovering crossed random effects in mixed-effects models using model averaging

Random effects contain crucial information to understand the variability of the processes under study in mixed-effects models with crossed random effects (MEMs-CR). Given that model selection makes all-or-nothing decisions regarding to the inclusion of model parameters, we evaluated if model averaging could deal with model uncertainty to recover random effects of MEMs-CR. Specifically, we analyzed the bias and the root mean squared error (RMSE) of the estimations of the variances of random effects using model averaging with Akaike weights and Bayesian model averaging with BIC posterior probabilities, comparing them with two alternative analytical strategies as benchmarks: AIC and BIC model selection, and fitting a full random structure. A simulation study was conducted manipulating sample sizes for subjects and items, and the variance of random effects. Results showed that model averaging, especially Akaike weights, can adequately recover random variances, given a minimum sample size in the modeled clusters. Thus, we endorse using model averaging to deal with model uncertainty in MEMs-CR. An empirical illustration is provided to ease the usability of model averaging.

Model Selection and Model Averaging for Mixed-Effects Models with Crossed Random Effects for Subjects and Items

A good deal of experimental research is characterized by the presence of random effects on subjects and items. A standard modeling approach that includes such sources of variability is the mixed-effects models (MEMs) with crossed random effects. However, under-parameterizing or over-parameterizing the random structure of MEMs bias the estimations of the Standard Errors (SEs) of fixed effects. In this simulation study, we examined two different but complementary perspectives: model selection with likelihood-ratio tests, AIC, and BIC; and model averaging with Akaike weights. Results showed that true model selection was constant across the different strategies examined (including ML and REML estimators). However, sample size and variance of random slopes were found to explain true model selection and SE bias of fixed effects. No relevant differences in SE bias were found for model selection and model averaging. Sample size and variance of random slopes interacted with the estimator to explain SE bias. Only the within-subjects effect showed significant underestimation of SEs with smaller number of items and larger item random slopes. SE bias was higher for ML than REML, but the variability of SE bias was the opposite. Such variability can be translated into high rates of unacceptable bias in many replications.

Synchronous bilateral laparoscopic adrenalectomy: Surgical technique and perioperative results of a 13-years' experience

INTRODUCTION AND OBJECTIVES

Laparoscopic surgery is the standard approach for the treatment of adrenal glands. Bilateral synchronous adrenalectomy is rarely performed, and evidence about this procedure is limited. Our objective is to report our 13-year experience with synchronous laparoscopic bilateral adrenalectomy, evaluating its feasibility, safety, and perioperative outcomes.

PATIENTS AND METHODS

A total of 23 consecutive patients undergoing synchronous bilateral laparoscopic adrenalectomy between 2007 and 2020 in a single academic center were included. Variables evaluated were operative time, estimated blood loss, conversion to open surgery, postoperative complications, mortality, and postoperative length of stay.

RESULTS

Mean operative time was 189.3 ± 48.9 min. Mean estimated blood loss was 163.0 ± 201.3 mL. There were no conversions to open surgery. Five patients had postoperative complications, three of those were major. No patient died in the perioperative period. Median postoperative length of stay was three days (range 1-30). At pathology analysis, 15 patients had bilateral adrenal hyperplasia, 2 unilateral adrenal hyperplasia and a contralateral benign tumor, 1 unilateral adrenal hyperplasia and a normal contralateral gland, 1 unilateral adenoma, 3 bilateral pheochromocytomas and 1 bilateral myelolipoma.

CONCLUSION

Synchronous bilateral laparoscopic adrenalectomy is a feasible and safe technique. A multidisciplinary and experienced team involving anesthesiologists and endocrinologists is required.

Dementia Family Caregivers’ Ambivalent Feelings and Cardiovascular Risk: Longitudinal Correlates

Cross-sectional data show that caregivers’ ambivalent feelings are associated with psychological distress. The association of ambivalent feelings with caregivers’ cardiovascular risk has not been studied. For this purpose we analyzed preliminary data from the Spanish Longitudinal Caregiving Spanish Longitudinal Study (CUIDA-LONG). One-year follow-up data were available for 96 dementia family caregivers. The following variables were assessed: sociodemographics, body mass index (BMI), disruptive behaviors, ambivalence, depressive symptomatology and cardiovascular risk with the inflammatory biomarker C-reactive protein (CRP). A hierarchical regression model was tested. Sociodemographic variables and change over time in stressors, ambivalence and depression were entered as predictors of change in CRP. 27% of the variance in CRP was explained through the model. More time since being a caregiver, higher BMI and greater increase in ambivalence contributed significantly to an increase in CRP. Ambivalent feelings contribute significantly to the cardiovascular risk of those who care for a relative with dementia.

The development of selective stopping: Qualitative and quantitative changes from childhood to early adulthood

Although progress has been made in elucidating the behavioral and neural development of global stopping across the lifespan, little is known about the development of selective stopping. This more complex form of inhibitory control is required in real-world situations where ongoing responses must be inhibited to certain stimuli but not others, and can be assessed in laboratory settings using a stimulus selective stopping task. Here we used this task to investigate the qualitative and quantitative developmental changes in selective stopping in a large-scale cross-sectional study with three different age groups (children, preadolescents, and young adults). We found that the ability to stop a response selectively to some stimuli (i.e., use a selective strategy) rather than non-selectively to all presented stimuli (i.e., use a global, non-selective strategy) is fully mature by early preadolescence, and remains stable afterwards at least until young adulthood. By contrast, the efficiency or speed of stopping (indexed by a shorter stop-signal reaction time or SSRT) continues to mature throughout adolescence until young adulthood, both for global and selective implementations of stopping. We also provide some preliminary findings regarding which other task variables beyond the strategy and SSRT predicted age group status. Premature responding (an index of "waiting impulsivity") and post-ignore slowing (an index of cognitive control) were among the most relevant predictors in discriminating between developmental age groups. Although present results need to be confirmed and extended in longitudinal studies, they provide new insights into the development of a relevant form of inhibitory control.

Stress, cognitive fusion and comorbid depressive and anxiety symptomatology in dementia caregivers

Comorbid depression and anxiety is linked to worse outcomes such as increased impairment, distress, and morbidity, as well as worse treatment outcomes. Transdiagnostic variables such as cognitive fusion are considered potential factors for explaining comorbidity. The aim of this study was to analyze the differences between symptom profiles of caregivers (comorbid, depressive, anxiety, and subclinical) in terms of demographic and contextual factors, stress variables, and cognitive fusion. Individual interviews were conducted with 553 caregivers of a relative with dementia. Sociodemographic variables, stressors, cognitive fusion, and depressive and anxiety symptoms were assessed. Caregivers were grouped into four symptom profiles, comorbid (n = 303), depressed (n = 40) anxiety (n = 86), and subclinical (n = 124), based on their depressive and anxiety symptoms. The likelihood of presenting a comorbid profile relative to the subclinical profile was higher in female caregivers. In addition, higher frequency of disruptive behaviors of the care recipient was a risk factor for presenting a comorbid profile relative to the other three profiles, and higher scores in cognitive fusion were a risk factor of comorbidity relative to the other profiles (anxiety, depressive, and subclinical). The findings suggest that the likelihood of presenting comorbid symptomatology is higher for female caregivers and those reporting higher levels of cognitive fusion and higher frequency of disruptive behaviors. These characteristics may describe a vulnerable profile of dementia family caregivers. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Emotional Valence Precedes Semantic Maturation of Words: A Longitudinal Computational Study of Early Verbal Emotional Anchoring

We present a longitudinal computational study on the connection between emotional and amodal word representations from a developmental perspective. In this study, children's and adult word representations were generated using the latent semantic analysis (LSA) vector space model and Word Maturity methodology. Some children's word representations were used to set a mapping function between amodal and emotional word representations with a neural network model using ratings from 9-year-old children. The neural network was trained and validated in the child semantic space. Then, the resulting neural network was tested with adult word representations using ratings from an adult data set. Samples of 1210 and 5315 words were used in the child and the adult semantic spaces, respectively. Results suggested that the emotional valence of words can be predicted from amodal vector representations even at the child stage, and accurate emotional propagation was found in the adult word vector representations. In this way, different propagative processes were observed in the adult semantic space. These findings highlight a potential mechanism for early verbal emotional anchoring. Moreover, different multiple linear regression and mixed-effect models revealed moderation effects for the performance of the longitudinal computational model. First, words with early maturation and subsequent semantic definition promoted emotional propagation. Second, an interaction effect between age of acquisition and abstractness was found to explain model performance. The theoretical and methodological implications are discussed.

Reciprocal relation between health and academic performance in children through autoregressive models

This study assessed the reciprocal predictive relation between multiple domains of health and academic performance (AP) in elementary schoolchildren through autoregressive models. A school-based longitudinal observational study was carried out, with a baseline measurement in 2014 and a follow-up at 12 and 24 months, in an Argentine sample of 533 children aged 9-13 years. Health was measured by self-administration of the KIDSCREEN-52 child version in the classroom, which evaluates 10 dimensions of health. AP was established with the final grades in language and mathematics obtained from the school records. Other variables collected were sex, mother's educational level, socioeconomic status, and intellectual capability. To examine the interdependencies between different health domains and AP, autoregressive and cross-lag coefficients between adjacent time points were calculated with structural equation modeling. A substantial portion of AP individual differences was explained by AP in the previous wave (β above .790). Conversely, health measures were not as stable between different waves (β around .400). Cross-lag path coefficients showed a significant dependence on health of previous-year AP, as can be seen in the physical well-being, psychological well-being, school environment, and social acceptance dimensions of health. AP also was influenced by previous-year health, as occurs with the self-perception, mood and emotions, and school environment health dimensions that significantly predict the next AP. These results are consistent with a positive two-way association between health and AP in childhood. This analysis is important to identify priority areas of intervention that could to improve both children's AP and well-being. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Development and Validation of the AdT-Physio Scale: A Tool to Assess Adherence and Perception of Physical Therapist Intervention in Patients With Cystic Fibrosis

OBJECTIVE

The purpose of this study was to develop a scale to measure patient adherence to physical therapist intervention and to report psychometric properties in patients with cystic fibrosis (CF).

METHODS

This observational, multicenter, qualitative, and cross-sectional study was divided into 2 phases: development of scale items (content validity) and assessment of psychometric properties (construct validity, reliability, and convergent/discriminant validity). Recruited were 121 patients with CF (aged ≥16 years). Sociodemographic characteristics, lung function testing, Coping with Stress Self-Efficacy, brief Coping Orientation to Problems Experienced inventory, and the scale of Adherence to Treatment of Physiotherapy (AdT-Physio) scale were evaluated.

RESULTS

The final version of the AdT-Physio scale consists of 15 items distributed across 2 subscales: compliance and beliefs about treatment/therapist. The scale showed high internal consistency (Cronbach α = .897; 95% CI = 0.868-0.922) and subscales above 0.800. The 2-factor confirmatory factor analysis model fitted the data reasonably well: χ2 (76) = 111.96, comparative fit index = 0.982, Tucker-Lewis index = 0.978, root mean square error of approximation = 0.063, 95% CI = 0.036 to 0.086, and weighted root mean square residual = 0.720. No floor or ceiling effects were identified. There was a positive, significant, and moderate-low magnitude correlation with the total Coping Orientation to Problems Experienced inventory (r = .360) and Coping with Stress Self-Efficacy subscale efficacy expectations scores (r = .304). For discriminant validity, there was a positive, significant, and moderate correlation between the total and the age of the patients (r = .354).

CONCLUSIONS

The AdT-Physio scale is psychometrically valid and reliable for use in the clinic for the assessment of adherence to physical therapy in patients with CF.

IMPACT

Ultimately, the authors propose this documentary instrument to assess the evaluation of the therapeutic alliance in a valid and objective manner. The AdT-Physio scale provides us with a greater degree of understanding of the problems behind noncompliance with treatment to advance person-centered decisions in physical therapy and thereby enhance the effectiveness of care.

Cultural aging stereotypes in European Countries: Are they a risk to Active Aging?

A growing body of literature acknowledges the association between negative stereotypes and individual components of active aging, but very few studies have tested this association, at both individual and population levels. The Stereotypes Content Model (SCM) states that the cultural aging stereotyping of higher warmth than competence (called paternalistic or ambivalent prejudice) is universal. Our aims in this study are to test the extent to which the universality of this stereotype is confirmed in European Countries as well as how far "positive", "negative" or "ambivalent" views towards older people, and other negative attitudes such as prejudice and behaviours such as discrimination, predict active aging assessed both at individual and population levels. We have analyzed data from the European Social Survey-2008 (ESS-2008), containing SCM stereotypical and other appraisal items (such as direct prejudice and perceived discrimination) about adults aged over-70 from 29 European countries. First, SCM cultural stereotypes about older adults ("friendly", "competent", and "ambivalent") were calculated; secondly, after developing a typology of countries based on their "negative", "ambivalent" and "positive" views about older adults, the universality of cultural stereotypes was tested; thirdly, taking into consideration ESS data of those older persons (over 70s) who self-reported indicators of active aging (health, happiness, satisfaction and social participation), multilevel analyses were performed, taking our inter-individual measure of active aging as dependent variable and our stereotypical classification (positive/negative/ambivalent), direct prejudice and perceived discrimination as predictors; finally, relationships between stereotypical and appraisal items on older adults were examined at population level with country data from Active Aging Indexes. Our results show cultural stereotypes about older people (more friendly than competent) are widespread in most European countries, and negative cultural views of older adults are negatively associated with active aging both at individual and population level, supporting that negative cultural views of older adults could be considered as a threat to active aging.

Measuring familism in dementia family caregivers: the revised familism scale

Objectives: Familism is a cultural value that has been shown to be important for understanding the dementia caregiving process. The aim of this study is to analyze the psychometric properties of the Revised Familism Scale (RFS).Method: Face-to-face assessments were done with 199 dementia family caregivers. Exploratory factor analysis, discriminant validity, and reliability analyses of the RFS were carried out.Results: The results suggest that the RFS has good psychometric properties and is composed of three factors: "Familial interconnectedness", "Familial obligations", and "Extended family support".Conclusion: The RFS seems to be a reliable measure of familism, a multidimensional construct measuring a relevant cultural value for dementia family caregivers.

Stress and Blood Pressure in Dementia Caregivers: The Moderator Role of Mindfulness

Objective: Dementia caregiving has been described as a chronically stressful situation with adverse cardiovascular effects. Psychological resources such as mindfulness may reduce the impact of stress on caregivers' cardiovascular health. The objective of this study was to analyze the moderating effect of trait mindfulness on the relationship between frequency of disruptive behaviors of the care recipient and blood pressure (BP) in dementia caregivers. Method: Participants were 110 dementia family caregivers. Two hierarchical regressions (for systolic and diastolic BP) were conducted to analyze whether mindfulness moderates the relationship between disruptive behaviors and BP after controlling for known predictors of cardiovascular outcomes. Results: A significant moderator effect of mindfulness was found between the frequency of disruptive behaviors and diastolic BP (β = -.195, p < .05). Among those caregivers reporting low levels of mindfulness, the relationship between frequency of disruptive behaviors and diastolic BP was relatively stronger than among those reporting high mindfulness levels. Conclusions: The results suggest that a high level of trait mindfulness may have protective effect on BP when caregivers face high levels of stress. Clinical Implications: Mindfulness seems to be an important variable with potential for buffering the effects of caregiving stressors on caregivers' blood pressure.

Bridging the theoretical gap between semantic representation models without the pressure of a ranking: some lessons learnt from LSA

In recent years, latent semantic analysis (LSA) has reached a level of maturity at which its presence is ubiquitous in technology as well as in simulation of cognitive processes. In spite of this, in recent years there has been a trend of subjecting LSA to some criticisms, usually because it is compared to other models in very specific tasks and conditions and sometimes without having good knowledge of what the semantic representation of LSA means, and without exploiting all the possibilities of which LSA is capable other than the cosine. This paper provides a critical review to clarify some of the misunderstandings regarding LSA and other space models. The historical stability of the predecessors of LSA, the representational structure of word meaning and the multiple topologies that could arise from a semantic space, the computation of similarity, the myth that LSA dimensions have no meaning, the computational and algorithm plausibility to account for meaning acquisition in LSA (in contrast to others models based on online mechanisms), the possibilities of spatial models to substantiate recent proposals, and, in general, the characteristics of classic vector models and their ease and flexibility to simulate some cognitive phenomena will be reviewed. The review highlights the similarity between LSA and other techniques and proposes using long LSA experiences in other models, especially in predicting models such as word2vec. In sum, it emphasizes the lessons that can be learned from comparing LSA-based models to other models, rather than making statements about "the best."

MCCB cognitive profile in Spanish first episode schizophrenia patients

The objective of the study was to examine the cognitive profile of Spanish patients with a first episode of schizophrenia (FESz) and to compare that to the profile of patients with a chronic schizophrenia (CSz) and non-psychiatric (NP) control subjects. The study included 106 FESz, 293 CSz, and 210 NP, assessed with the Spanish version of the MATRICS Consensus Cognitive Battery (MCCB). The MCCB cognitive profile in a Spanish sample of FESz was similar to the cognitive profile of CSz with some discrepancies in select domains. The scores of both patient samples were about 1-2 SD below the scores of non-psychiatric control subjects.

A training intervention to reduce paternalistic care and promote autonomy: a preliminary study

Introduction

Paternalism, assuming control of aged care, is a widespread orientation in older adults care. Paternalistic attitudes and practices are commonly understood as a threat to the freedom and autonomy of a person, making patients more dependent. Therefore, the reduction of these attitudes and behaviors is a primary goal for any older adult health and social care situation. The aim of this preliminary study is to develop a behavioral intervention to decrease paternalistic behaviors in formal caregivers and to increase those care behaviors which promote autonomy at post-intervention (1 week) and at follow-up (14 weeks).

Methods

A sample of 118 professional caregiver volunteers working in day care centers and nursing homes were assigned to quasi-experimental (N=47) and control (N=71) conditions. The intervention consisted of 3 weekly group sessions. Individual and contextual measures were collected: 1) the primary outcome variable was the type of care (paternalistic versus autonomist) measured through the self-report Paternalist/Autonomist Care Assessment (PACA); 2) A 10-item caregiver self-register of paternalistic behaviors was carried out, 3) Finally, in order to assess the potential effects on observed behavior both in caregiver and older adult functioning at a contextual level, the five institutions were assessed through the SERA-RS.

Results

Compared with the control group, caregivers in the behavioral intervention group displayed significantly lower paternalistic appraisals at posttest and follow-up. Regarding the intervention group, caregivers at posttest and follow-up showed significantly greater occurrence of autonomist behaviors being promoted and lower paternalistic appraisal. The results regarding the effect on the institutions showed better personnel performance and older adult functioning.

Conclusion

Caregivers who followed the intervention learned to better identify older adult needs; although we did not find significant differences in autonomy occurrence compared with the control group, a behavioral intervention may promote more autonomist environments and, therefore, better personnel and older adult functioning.

Development and validation of a paternalism and autonomist care assessment

AIM

There is a need for a validated instrument to measure the type of care (paternalism or person-centred) provided for older adults. Since paternalism and person-centred care are the most important caregiving styles in the field of care and as they are usually opposed, the study aims to develop and establish psychometrics data of an instrument to identify paternalistic and autonomist behaviours in older adults care contexts, which can help to enhance care practice.

DESIGN

Instrument development.

METHODS

After observing and standardizing behaviours in formal care contexts in 2016, an instrument was developed and proceeding to a first validation using standard validation techniques among caregivers in two care settings during 2016-2017: senior citizen centres and older adult day care centres.

RESULTS

The Paternalist/Autonomist Care Assessment (PACA) is a 30-item, behaviour-based instrument which measures both the appraisal of caregivers on elements of care (Care Appraisal Scale- PACA-Appraisal) and the occurrence of behaviours (Occurrence of Care in Context- PACA-Occurrence). The Paternalist/Autonomist Care Assessment (PACA) was validated in 160 professional caregivers and was able to discriminate two factors: paternalistic or overprotective behaviours and autonomist behaviours. However, these factors were not fully dichotomous and were shown to coexist to some degree.

CONCLUSION

The instrument displayed good psychometric properties to measure paternalism and autonomy in older adult care. Moreover, it showed that the two types of care are not antagonistic and can coexist, with overprotective behaviours being more frequent in contexts of care for more dependent persons.

IMPACT

There are no validated instruments to measure paternalism and person-centred behaviour in care contexts. The two measures yielded by the PACA show good construct and concurrent empirical validity, internal consistency, and convergent and discriminant validity.

Metacomprehension skills depend on the type of text: An analysis from Differential Item Functioning

BACKGROUND

Metacomprehension skills determine an individual reader's ability to judge their degree of learning and text comprehension and have considerable importance in their ability to learn from reading. Given that many comprehension processes are influenced by text characteristics, the aim of the present study was to analyze whether different types of text have significant impact on metacomprehension skills at two different points in primary education.

METHOD

A total of 823 students (4th and 6th years of primary school, 9 to 11 years old) read three different texts (narrative, expository and discontinuous texts) taken from ECOM-PLEC.Pri, a standardized Spanish test for reading comprehension (León, Escudero, & Olmos, 2012). Students were classified by their metacomprehension skills. A Differential Item Functioning (DIF) analysis was conducted in order to analyze whether the underlying reading comprehension and metacomprehension processes differed across text types.

RESULTS

Results showed a considerable divergence of performance for reading narrative texts as opposed to expository and discontinuous texts. These differences were related to academic level.

CONCLUSION

Text characteristics such as the type of text can have a great impact on metacomprehension skills and, consequently, on learning.

Cultural stereotypes in care contexts

INTRODUCTION

The main goal of the present study was to examine the stereotype content model (SCM) assumption for universality and to test whether the mediating role of cultural views about older adult caregivers is maintained in other health care contexts.

METHODS

One hundred and sixty professionals and volunteers who worked with older adults in day care centers (DCCs) and senior citizen centers (SCCs) and 1,151 participants from a representative sample of the Spanish population were examined using the SCM questionnaire; older adult and personnel functioning were assessed through an observation procedure with two subscales of the Evaluation Scale from the Sistema de Evaluación de Residencias de Ancianos.

RESULTS

The results showed that the context does not seem to influence the cultural views about older adults held by caregivers. All results support the cultural stereotype pattern in which members of the older adult group are viewed with high warmth (HW) and low competence (LC) as posited by the SCM model. With respect to the mediation of cultural stereotypes on caregivers/older adult functioning, this has not been supported in this study. Neither cultural views of warmth (predicted by the SCM) nor views of competence (from our previous studies) influence either caregiver functional behaviors or older adult functioning.

CONCLUSION

Two post hoc hypotheses can be inferred: 1) there is more variability in competence and warmth in DCCs and SCCs and 2) although we did not find significant differences in the pattern of competence and warmth in perceived cultural stereotypes about older adults, more healthy environments could reduce the influence of cognitive views on behavior.

Assessing aging stereotypes: Personal stereotypes, self-stereotypes and self-perception of aging

BACKGROUND

There is a broad semantic network of aging stereotypes; where different concepts and their measurement are confused: personal stereotypes, self-stereotypes and self-perception of aging.

METHOD

First, we analyze the translated version of the Image of Aging Scale (IAS) measurement model through exploratory and confirmatory factor analysis, with two representative sub-samples of the Spanish population aged over eighteen (N = 1,105) and in a sample of gerontologists and geriatricians (N = 325). Second, in an effort to disentangle the theoretical relationships between personal stereotypes, self-stereotypes and self-perception of aging, both the IAS (with different instructions) and Lawton&rsquo;s 5-item scale were administered to a representative sample of Spanish people over 50.

RESULTS

Our results indicate that the Spanish version of the IAS has a similar psychometric structure to that proposed by the authors. Furthermore, the factorial structure (equal form and metric invariance) is replicated in both samples, but latent means and factor correlations were higher in the professional group.

CONCLUSIONS

We discuss Levy&rsquo;s theoretical assumptions about personal-stereotypes and the self-stereotype measured with IAS and their relationship to self-perception of ageing.

Word maturity indices with latent semantic analysis: why, when, and where is Procrustes rotation applied?

The aim of this paper is to describe and explain one useful computational methodology to model the semantic development of word representation: Word maturity. In particular, the methodology is based on the longitudinal word monitoring created by Kirylev and Landauer using latent semantic analysis for the representation of lexical units. The paper is divided into two parts. First, the steps required to model the development of the meaning of words are explained in detail. We describe the technical and theoretical aspects of each step. Second, we provide a simple example of application of this methodology with some simple tools that can be used by applied researchers. This paper can serve as a user-friendly guide for researchers interested in modeling changes in the semantic representations of words. Some current aspects of the technique and future directions are also discussed.

The role of perceived discrimination on active aging

Among older adults, perceived age discrimination is highly associated with unhealthy outcomes and dissatisfaction. Active aging is a multidimensional concept described by a set of characteristics, particularly health, positive mood and control; most importantly, active aging is currently at the core of public policies. The aim of the present study was to test to what extent perceived discrimination influences active aging. Methods A total of 2005 older adults in three representative samples from regions of Germany, Mexico and Spain participated; they were tested on active aging and perceived discrimination. First, active aging was defined as high reported health, life satisfaction and self-perception of aging. Second, authors introduced the assumption that, in the total sample, structural equation modelling would confirm the hypothesis of a direct negative link between perceived age discrimination and active aging. Finally, multiple group comparison performed through structural equation modelling also provided support for the negative association between perceived discrimination and active aging proposed. In spite of the differences found among the three countries in both active aging variables and age discrimination perception, multiple group comparison indicates that regardless of the culture, perceived discrimination is a negative predictor of active aging.

Inconsistencies in Reported p-Values in Spanish Journals of Psychology

Abstract. Correlation analysis is one of the most widely used methods to test hypotheses in social and health sciences; however, its use is not completely error free. We have explored the frequency of inconsistencies between reported p-values and the associated test statistics in 186 papers published in four Spanish journals of psychology (1,950 correlation tests); we have also collected information about the use of one- versus two-tailed tests in the presence of directional hypotheses, and about the use of some kind of adjustment to control Type I errors due to simultaneous inference. Reported correlation tests (83.8%) are incomplete and 92.5% include an inexact p-value. Gross inconsistencies, which are liable to alter the statistical conclusions, appear in 4% of the reviewed tests, and 26.9% of the inconsistencies found were large enough to bias the results of a meta-analysis. The election of one-tailed tests and the use of adjustments to control the Type I error rate are negligible. We therefore urge authors, reviewers, and editorial boards to pay particular attention to this in order to prevent inconsistencies in statistical reports.

15 THERMORESISTANCE SPERM TEST FOR EPIDIDYMAL STALLION SPERM FROZEN WITH TWO CRYOPROTECTANTS

The Peruvian Paso Horse has become a flagship product of Peru, for which it is very important to work on promoting and preserving their genetic material through semen. The objective of this study was to evaluate the thermoresistance of epididymal sperm of stallion frozen with 2 cryoprotectants (dimethylformamide and glycerol). The testes with the epididymides (n = 16) of 8 adult stallions in good health condition were obtained in the slaughter house and transport at isothermal conditions (30°C). Spermatozoa from the epididymis were recovered and incubated with lactated ringer's solution (Hartman solution) for 30 min, centrifuged at 2000 RPM for 15 min, and resuspended with an extender based on sucrose (7%) and egg yolk (3%) with different levels of cryoprotectants: dimethylformamide-DMF (T4%), glycerol-GLI (4%), and a combination of dimethylformamide-DMF (2%) + glycerol-GLI (2%) with an equilibrium time of 20 min at 5°C. The final dilution was 160 million motile spermatozoa placed on 0.5-mL straws. These straws were kept over liquid nitrogen fumes for 15 min over a tripod stand. After cryopreservation, the straws were stored in liquid nitrogen tanks (–196°C). The thawing process of the straws was initiated at 75°C for 7 s, immediately followed by an evaluation of sperm motility at 4 times 0, 30, 60, and 90 min in which sperm was incubated on water bath at 37°C (thermoresistance test). The data was evaluated (ANOVA) with the SAS 9.12 program (SAS Institute Inc., Cary, NC, USA) and, for the media, Tukey's test was carried out. The results showed an effect of the treatment on the motility of the frozen-thawed semen; dimethylformamide, the cryoprotectant, had the best performance.

Evaluation by SPECT-CT of an incidental finding of a thymoma and breast cancer in a myocardial perfusion SPECT with 99mTc-MIBI

We present a case of a 78-year-old female with effort angina. A myocardial perfusion SPECT (MPS) showed increased tracer uptake in two synchronic tumor lesions, a thymoma and a breast cancer. This case highlights the contribution of SPECT-CT in the characterization of these findings and its essential role in rapid decision-making. The patient underwent surgery of both lesions that had gone undetected prior to the conduction of the MPS.

SPECT-CT in the localization of an ectopic retropharyngeal parathyroid adenoma as a cause for persistent primary hyperparathyroidism

A common cause for surgical failure of primary hyperparathyroidism (pHPT) is the non-detection of an ectopic adenoma during the intervention. We present a case of a patient with pHPT in whom an ectopic gland was found in the right retropharyngeal space by means of a double phase (99m)Tc-methoxy-isobutyl-isonitrile ((99m)Tc-MIBI) scintigraphy and early SPECT-CT after several surgeries and imaging tests. The addition of a tomography to the planar scintigraphy increases its sensitivity and improves pathological parathyroid glands localization. The hybrid imaging is sometimes essential to obtain surgical success, as in the case of ectopic adenomas.

Assessing short summaries with human judgments procedure and latent semantic analysis in narrative and expository texts

In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries, summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence text). A total of 390 Spanish middle and high school students (14-16 years old) and six experts read a narrative or expository text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository, and LSA correlated more with human content ratings thanwith hu mancoherence ratings. Finally, theholistic methods were found to be more reliable than the componential methods analyzed in this study.
