The Poses for Equine Research Dataset (PFERD).

Studies of quadruped animal motion help us to identify diseases, understand behavior and unravel the mechanics behind gaits in animals. The horse is likely the best-studied animal in this aspect, but data capture is challenging and time-consuming. Computer vision techniques improve animal motion extraction, but the development relies on reference datasets, which are scarce, not open-access and often provide data from only a few anatomical landmarks. Addressing this data gap, we introduce PFERD, a video and 3D marker motion dataset from horses using a full-body set-up of densely placed over 100 skin-attached markers and synchronized videos from ten camera angles. Five horses of diverse conformations provide data for various motions from basic poses (eg. walking, trotting) to advanced motions (eg. rearing, kicking). We further express the 3D motions with current techniques and a 3D parameterized model, the hSMAL model, establishing a baseline for 3D horse markerless motion capture. PFERD enables advanced biomechanical studies and provides a resource of ground truth data for the methodological development of markerless motion capture.

Mediating role of splitting in relation to attachment styles and shopping addiction.

Introduction: Shopping can provide a sense of satisfaction and pleasure; however, if a person's excessive involvement in this behavior starts to negatively impact other aspects of their life, similar to other addictive behaviors like excessive internet use, gaming, and gambling, it may be classified as pathological. Given the lack of agreement regarding the classification of excessive shopping tendencies as a separate mental health condition or addictive behavior, taking a socio-emotional approach to explore the psychological factors that precede this behavior, may offer a better comprehension of it. Methods: The purpose of this study was to examine the relationship between attachment styles and excessive shopping behavior, as well as to investigate the potential mediating effect of defense mechanisms like splitting on this relationship. Using convenience sampling, a group of 457 stock market employees (116 female, 341 male) between the ages of 24 and 60 were recruited. The researchers utilized a set of validated psychological questionnaires to assess the employees attachment styles, shopping addiction, and splitting tendencies. Results: The results obtained from both the mediation model and path analysis suggest that attachment styles do not have a direct relationship with shopping addiction. Nonetheless, the study supports the impact of insecure anxious and avoidan attachment styles on splitting. Furthermore, the findings confirm that splitting has a mediating effect on the relationship between attachment styles and splitting. Discussion: The present study enhanced our comprehension of the subconscious mechanisms underlying shopping tendencies. Specifically, the findings suggest that excessive tendencies towards shopping can be considered a maladaptive response resulting from insecure attachment styles and the unconscious utilization of the splitting defense mechanism.

Investigation of wavy microchannel ability on electronic devices cooling with the case study of choosing the most efficient microchannel pattern.

A numerical study was conducted to investigate the ability of wavy microchannels to damp the temperature fluctuations generates in electronic devices. Five wavy patterns are considered with the amplitude and wavelength in the ranges of 62.5 to 250 µm and 1250 to 5000 µm, respectively to study the effect of governing phenomena of flow within wavy patterns on thermal-hydraulic performance. The flow regime is laminar and the Reynolds number is in the range of 300 to 900, and a relatively high heat flux of 80 W/cm2 is applied to the microchannels substrate. Also, variable flux condition is studied for heat fluxes of 80, 120, 160, 200, and 240 W/cm2 and for the most efficient wavy and straight microchannels. Results showed that the geometries with larger amplitude to wavelength ratio have a lower radius of curvature and larger Dean number, and as a result of transverse flow (secondary flow) amplification, they have enhanced heat transfer. Also, by comparing the ratio of the transverse velocity components to the axial component, it was found that by decreasing the radius of curvature and increasing the Dean number, transverse velocity increases, which intensifies the heat transfer between the wall and the fluid. The appraisement of the performance evaluation criterion (PEC) illustrates that the wavy case with an amplitude of 250 µm and wavelength of 2500 µm is the best geometry from the thermal-hydraulic point of view in the studied range. Finally, with variable flux condition, the wavy microchannel has responded well to the temperature increase and has created a much more uniform surface temperature compared to straight pattern. The proposed wavy pattern ensures that there are no hotspots which could damage the electronic chip. Presented wavy patterns can be used in heat sinks heat transfer enhancement to allow the chip to run in higher heat fluxes.

Recollections of Childhood Sexual Abuse: Complexities of Religious Coping and Muslim Religious and Psychological Adjustment in Afghanistan.

Religious coping is a double-edged sword. Clarification of the psychological benefits for positive religious coping requires statistical controls for negative religious coping and vice versa. This study sought to further explore the complexities of Muslim religious coping by extending the analysis to Afghans who coped with the sufferings associated with recollections of childhood and adolescent sexual abuse. Two hundred Dari Persian-speaking Afghan university students (122 identified having experience of childhood sexual abuse) self-reported on variables that measure religious orientation, religious coping, Muslim experiential religiousness, mental health, and child abuse. Results showed that negative religious coping interfered with the possibly beneficial effects of positive religious coping on mental health and child abuse. After controlling for negative religious coping, the associations of positive religious coping became obvious. In addition, Muslim spirituality moderated the associations of religious coping with mental health outcomes and child abuse: for people with higher Muslim spirituality, positive religious coping associated with better mental health, and negative religious coping associated with less child abuse. Implications for religious coping and combating trauma in a religious context are discussed.

Exploring the mediating role of integrative self-knowledge in the relationship between mindfulness and well-being in the context of a mindfulness-based stress reduction program.

Mindfulness-based stress reduction (MBSR) is an effective program for improving well-being. A growing body of studies is exploring the mechanisms mediating its beneficial effects. Integrative self-knowledge (ISK) is the construct of focus in this study. The primary goal of the current study was to investigate the mediating role of ISK in the relationship between improved mindful observing (MO), non-judging inner experience (NJ), and well-being following an MBSR program with an Iranian sample. Participants (n = 118) enrolled in MBSR and completed depression, anxiety, stress (DASS), Bartone Symptoms Checklist (BSC), Five-Facet Mindfulness Questionnaire, and ISK scale before and after the program. Results showed significant reductions in BSC, DASS, and improvements in MO, NJ, and ISK at the end of the program. Mediation analyses revealed that changes in ISK significantly mediated the relationship between changes in MO and NJ and symptoms (MO indirect effect on DASS: ß = 0.11, confidence interval [CI] [0.003, 0.29]; NJ indirect effect on DASS: ß = 0.12, CI [-0.16, 0.45]; MO indirect effect on BSC: ß = 0.08, CI [0.001, 0.27]; NJ indirect effect on BSC: ß = 0.09, CI [0.01, 0.22]). Improvements in MO and NJ may provide a pathway to cultivating ISK in MBSR, which may lead to enhanced well-being.

A bias of self-reports among repressors: Examining the evidence for the validity of self-relevant and health-relevant personal reports.

Studies have shown that repressors tend to respond to self-report tools in a positive fashion which distorts the findings of studies based on questionnaires. The present study aimed to examine the way repressors respond to "Self-relevant" scales (which assess variables related to adaptive self-function) in comparison to "Health-relevant" scales (which assess physical and psychological health). Iranian university students (N = 271) responded to the Weinberger Adjustment Inventory (to differentiate between repressors and self-assured individuals), Mindful Attention and Awareness Scale, Self-control Scale, Integrative Self-knowledge Scale and Self-compassion Scale (to measure self-relevant variables), Bartone Symptoms checklist and the Depression and Anxiety Subscales of Depression, Anxiety and Stress Subscale (DASS-21) (to measure health-relevant variables). Based on responses to the Weinberger Adjustment Inventory, 101 participants fell into two groups, including repressors and self-assured individuals, and their data were further analysed. Multivariate analysis of variance showed no difference in repressors' scores in health-relevant scales compared to the self-assured group (healthy individuals), but they reported higher scores in adaptive self-relevant scales compared to the self-assured individuals. This study provides new evidence that compared to self-assured individuals, repressors differ in the way they respond to self-relevant versus health-relevant scales.

Examining the factor structure of the Self-Compassion Scale in 20 diverse samples: Support for use of a total score and six subscale scores.

This study examined the factor structure of the Self-Compassion Scale (SCS) using secondary data drawn from 20 samples (N = 11,685)-7 English and 13 non-English-including 10 community, 6 student, 1 mixed community/student, 1 meditator, and 2 clinical samples. Self-compassion is theorized to represent a system with 6 constituent components: self-kindness, common humanity, mindfulness and reduced self-judgment, isolation and overidentification. There has been controversy as to whether a total score on the SCS or if separate scores representing compassionate versus uncompassionate self-responding should be used. The current study examined the factor structure of the SCS using confirmatory factor analyses (CFA) and Exploratory Structural Equation Modeling (ESEM) to examine 5 distinct models: 1-factor, 2-factor correlated, 6-factor correlated, single-bifactor (1 general self-compassion factor and 6 group factors), and 2-bifactor models (2 correlated general factors each with 3 group factors representing compassionate or uncompassionate self-responding). Results indicated that a 1- and 2-factor solution to the SCS had inadequate fit in every sample examined using both CFA and ESEM, whereas fit was excellent using ESEM for the 6-factor correlated, single-bifactor and correlated 2-bifactor models. However, factor loadings for the correlated 2-bifactor models indicated that 2 separate factors were not well specified. A general factor explained 95% of the reliable item variance in the single-bifactor model. Results support use of the SCS to examine 6 subscale scores (representing the constituent components of self-compassion) or a total score (representing overall self-compassion), but not separate scores representing compassionate and uncompassionate self-responding.

Self-Compassion and Cultural Values: A Cross-Cultural Study of Self-Compassion Using a Multitrait-Multimethod (MTMM) Analytical Procedure.

Self-compassion is natural, trainable and multi-faceted human capacity. To date there has been little research into the role of culture in influencing the conceptual structure of the underlying construct, the relative importance of different facets of self-compassion, nor its relationships to cultural values. This study employed a cross-cultural design, with 4,124 participants from 11 purposively sampled datasets drawn from different countries. We aimed to assess the relevance of positive and negative items when building the self-compassion construct, the convergence among the self-compassion components, and the possible influence of cultural values. Each dataset comprised undergraduate students who completed the "Self-Compassion Scale" (SCS). We used a confirmatory factor analysis (CFA) approach to the multitrait-multimethod (MTMM) model, separating the variability into self-compassion components (self-kindness, common humanity, mindfulness), method (positive and negative valence), and error (uniqueness). The normative scores of the Values Survey Module (VSM) in each country, according to the cultural dimensions of individualism, masculinity, power distance, long-term orientation, uncertainty avoidance, and indulgence, were considered. We used Spearman coefficients (r s) to assess the degree of association between the cultural values and the variance coming from the positive and negative items to explain self-compassion traits, as well as the variance shared among the self-compassion traits, after removing the method effects produced by the item valence. The CFA applied to the MTMM model provided acceptable fit in all the samples. Positive items made a greater contribution to capturing the traits comprising self-compassion when the long-term orientation cultural value was higher (r s = 0.62; p = 0.042). Negative items did not make significant contributions to building the construct when the individualism cultural value was higher, but moderate effects were found (r s = 0.40; p = 0.228). The level of common variance among the self-compassion trait factors was inversely related to the indulgence cultural value (r s = -0.65; p = 0.030). The extent to which the positive and negative items contribute to explain self-compassion, and that different self-compassion facets might be regarded as reflecting a broader construct, might differ across cultural backgrounds.

Religious and Psychological Implications of Positive and Negative Religious Coping in Iran.

This study examined the religious and psychological implications of religious coping in Iran. University students (N = 224) responded to the Brief Positive and Negative Religious Coping Scales along with measures of Religious Orientation, Integrative Self-Knowledge, Self-Control, Mindfulness, Self-Compassion, Self-Esteem, Guilt, Shame, and Self-Criticism. As in previous research elsewhere, Positive Religious Coping was stronger on average than Negative Religious Coping, and Positive and Negative Religious Coping predicted adjustment and maladjustment, respectively, In addition, this study demonstrated that direct relationships between Positive and Negative Religious Coping appeared to be reliable in Iran; that Positive Religious Copings was broadly compatible with, and Negative Religious Coping was largely irrelevant to, Iranian religious motivations; and that Negative Religious Coping obscured linkages of Positive Religious Coping with religious and psychological adjustment.

Integrative self-knowledge and marital satisfaction.

Married Iranian couples (N = 210) responded to the Integrative Self-Knowledge Scale along with a measure of marital satisfaction, the International Personality Item Pool (IPIP) Big Five, and an index of interpersonal problems. Integrative self-knowledge correlated positively with marital satisfaction, positively with all but the extraversion Big Five traits, and negatively with three indices of interpersonal problems. Integrative self-knowledge also mediated a number of personality relationships with marital satisfaction. Spouse-ratings of personality confirmed the adaptive implications of integrative self-knowledge for marriage. Linkages with questionnaire response styles supported the description of integrative self-knowledge as a measure of both self-insight and self-development. Results confirmed the potential of integrative self-knowledge for studying self-regulatory processes and suggested that the enhancement of self-knowledge may be a useful goal in efforts to strengthen marriages.

A multi-process model of self-regulation: influences of mindfulness, integrative self-knowledge and self-control in Iran.

Self-regulation presumably rests upon multiple processes that include an awareness of ongoing self-experience, enduring self-knowledge and self-control. The present investigation tested this multi-process model using the Five-Facet Mindfulness Questionnaire (FFMQ) and the Integrative Self-Knowledge and Brief Self-Control Scales. Using a sample of 1162 Iranian university students, we confirmed the five-factor structure of the FFMQ in Iran and documented its factorial invariance across males and females. Self-regulatory variables correlated negatively with Perceived Stress, Depression, and Anxiety and positively with Self-Esteem and Satisfaction with Life. Partial mediation effects confirmed that self-regulatory measures ameliorated the disturbing effects of Perceived Stress. Integrative Self-Knowledge and Self-Control interacted to partially mediate the association of Perceived Stress with lower levels of Satisfaction with Life. Integrative Self-Knowledge, alone or in interaction with Self-Control, was the only self-regulation variable to display the expected mediation of Perceived Stress associations with all other measures. Self-Control failed to be implicated in self-regulation only in the mediation of Anxiety. These data confirmed the need to further examine this multi-process model of self-regulation.

Mindfulness and integrative self-knowledge: relationships with health-related variables.

This study examined how mindfulness and integrative self-knowledge were related to health-related issues. Men in general population (n = 103) and coronary heart disease samples (n = 101) completed the Mindful Attention Awareness Scale, the Integrative Self-knowledge Scale, the Type 2 subscale of the Interpersonal Reactions Inventory, the Perceived Stress Scale, and the Anxiety and Depression Scales. In both samples, there was a moderate positive correlation between mindfulness and integrative self-knowledge and they were negatively correlated with all health-related variables. However, only integrative self-knowledge explained independent variance in health-related variables. Specifically, in both samples, the relationship between mindfulness and health-related variables was mediated by integrative self-knowledge. Mindfulness and integrative self-knowledge are related domains of self-awareness that are associated with a range of health-related variables. These relationships are robust across samples drawn from general population and patients with coronary heart disease. The finding that integrative self-knowledge explained additional variance in the health-related variables after the contribution of mindfulness had been accounted for suggests that reflective self-awareness in integrative self-knowledge may make a unique contribution to the explanation of individual differences in health variables.

Comparative analysis of integrative self-knowledge, mindfulness, and private self-consciousness in predicting responses to stress in Iran.

Previous research has established that awareness of self-experience is a stress resistance resource. The present study conducted an analysis of measures that record different aspects of self-awareness (private self-consciousness, mindfulness, and integrative self-knowledge) to explain this stress-resistance effect in a sample of Iranian university students (N = 186). These students responded to Mindfulness Attention Awareness, Private Self-Consciousness, Integrative Self-Knowledge, and Perceived Stress Scales just before the stress of a 20-day final examination period, and they then responded to Symptom Checklist and Vitality measures at four-day intervals during the final examinations. Prior to final examinations, the three self-awareness variables correlated positively with each other and negatively with perceived stress. Regression analyses of the data obtained during final examinations identified mindfulness to be a better operationalization of this stress-resistance resource than private self-consciousness. Specifically, mindfulness but not private self-consciousness was a positive predictor of vitality and a negative predictor of symptoms. Hierarchical regression analyses also demonstrated that mindfulness and integrative self-knowledge both explained resistance to physical symptoms, while integrative self-knowledge functioned as a protective factor toward one's vitality. These data confirm the positive impact that self-awareness has during stress and highlight the importance of considering both mindfulness and integrative self-knowledge in understanding stress-resistance processes.

Integrative Self-Knowledge Scale: correlations and incremental validity of a cross-cultural measure developed in Iran and the United States.

The authors used Iranian (N = 723) and American (N = 900) samples to develop an Integrative Self-Knowledge Scale for measuring a temporally integrated understanding of processes within the self. They administered this new instrument, the Mindfulness Scale (K. W. Brown & R. M. Ryan, 2003), the Reflective and Experiential Self-Knowledge Scales (N. Ghorbani, M. N. Bing, P. J. Watson, H. R. Davison, & D. L. Lebreton, 2003), and additional sample-specific measures to 3 separate groups of university students in each society. The Integrative Self-Knowledge Scale displayed internal reliability and measurement equivalence, along with convergent, criterion, discriminant, and incremental validity. This new instrument may be useful in promoting cross-cultural research in positive psychology.

Relationship of perceived stress with depression: complete mediation by perceived control and anxiety in Iran and the United States.

This study sought to clarify the importance and cross-cultural relevance of associations between generalized perceived stress and depression. Also tested was the hypothesis that perceived stress would correlate more strongly with anxiety than with depression, whereas control would be more predictive of depression than of anxiety. Relationships between perceived stress, anxiety, depression, and perceived control were examined in samples of Iranian (n = 191) and American (n = 197) undergraduates. Correlations among these variables were generally similar across the two societies. Perceived stress did predict anxiety better than depression, but perceptions of control predicted depression significantly better than anxiety only in the United States. Best fitting structural equation models revealed that anxiety and perceived control completely accounted for the linkage between perceived stress and depression in both societies. An equally acceptable and more parsimonious model described perceived stress as a consequence rather than as an antecedent of anxiety and perceived control. Structural equation models were essentially identical across the two cultures except that internal control displayed a significant negative relationship with anxiety only in Iran. This result seemed to disconfirm any possible suggestion that a supposedly individualistic process like internal control could have no noteworthy role within a presumably more collectivistic Muslim society like Iran. Overall, these data documented the importance of anxiety and perceived control in explaining the perceived stress-depression relationship cross-culturally and therefore questioned the usefulness of perceived stress in predicting depression. Whether this understanding of the stress-depression relationship deserves general acceptance will require additional studies that measure the frequency of stressful life events and that utilize a longitudinal design.

Relationship of self-reported mysticism with depression and anxiety in Iranian Muslims.

This study examined relationships of self-reported Mysticism with dispositional Depression and Anxiety in Iranian Muslims. The sample contained 80 women and 51 men undergraduates who volunteered to participate (M age=20.5 yr., SD= 2.0). Participants responded to the Hood Mysticism Scale and to the Costello and Comrey Depression and Anxiety Scales. Scores on the Religious Interpretation dimension of mystical experience correlated negatively with those on Depression, explained a similar relationship observed for Extrovertive Mysticism, and moderated the otherwise positive relationship between Introvertive Mysticism and Anxiety. Moderation occurred when Introvertive Mysticism correlated negatively rather than positively with Anxiety in those who scored high on Religious Interpretation and very high on the Introvertive factor. These data suggested possibilities for reconciling conflicts that have appeared between philosophical interpretations of Introvertive Mysticism and previous self-report data.

Validity of Experiential and Reflective Self-knowledge Scales: relationships with basic need satisfaction among Iranian factory workers.

This study examined the validity of Experiential and Reflective Self-knowledge Scales in a sample of Iranian factory workers. Both scales were administered to 321 male and 12 female workers (M age= 35.6 yr., SD= 8.9) along with the Basic Need Satisfaction at Work Scales, the Work Climate Questionnaire, and measures of Perceived Stress and Self-esteem. Scores on the two self-knowledge measures correlated with all other variables consistent with the claim of Self-determination Theory that self-insight is associated with a more complete satisfaction of basic needs. In a number of multiple regression analyses, Reflective and Experiential Self-knowledge combined to explain variance in other measures. These data further supported the validity of the two new Self-knowledge Scales.

Relationships of Experiential and Reflective Self-Knowledge with Trait Meta-Mood Scale, constructive thinking inventory, and the Five Factors in Iranian managers.

The purpose of this study was to examine the validity and the incremental validity of recently developed Reflective and Experiential Self-knowledge Scales. Along with measures of the Five Factors and of psychological adjustment, 201 male Iranian managers responded to the Self-knowledge Scales along with tests relevant to emotional intelligence, including the Trait Meta-mood Scale and the Constructive Thinking Inventory. As hypothesized, Self-knowledge Scales predicted greater self-reported emotional intelligence. Multiple regression also confirmed the incremental validity of these scales, showed each explained a separate source of variance, and supported the presumed temporal dynamics that theoretically underlie these constructs.

Hardiness scales in Iranian managers: evidence of incremental validity in relationships with the five factor model and with organizational and psychological adjustment.

This study examined the incremental validity of Hardiness scales in a sample of Iranian managers. Along with measures of the Five Factor Model and of Organizational and Psychological Adjustment, Hardiness scales were administered to 159 male managers (M age = 39.9, SD = 7.5) who had worked in their organizations for 7.9 yr. (SD=5.4). Hardiness predicted greater Job Satisfaction, higher Organization-based Self-esteem, and perceptions of the work environment as being less stressful and constraining. Hardiness also correlated positively with Assertiveness, Emotional Stability, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness and negatively with Depression, Anxiety, Perceived Stress, Chance External Control, and a Powerful Others External Control. Evidence of incremental validity was obtained when the Hardiness scales supplemented the Five Factor Model in predicting organizational and psychological adjustment. These data documented the incremental validity of the Hardiness scales in a non-Western sample and thus confirmed once again that Hardiness has a relevance that extends beyond the culture in which it was developed.

Constructive thinking inventory: evidence of validity among Iranian managers.

This study examined the validity and incremental validity of the Constructive Thinking Inventory in a sample of Iranian managers. These 159 men were 39.9 yr. old (SD=2.5) and volunteered to participate in a project in which they responded to the Constructive Thinking Inventory, the Big Five Factors, the Costello and Comrey Depression and Anxiety Scales, and the Perceived Stress Scale. Numerous findings confirmed the validity of the Constructive Thinking Inventory, and the Global Constructive Thinking subscale displayed incremental validity. These data supported the validity of the Constructive Thinking Inventory and its associated theoretical assumptions in a sample of Iranian managers.
