“There Is No (Where a)FaceLike Home”: Recognition and Appraisal Responses to Masked FacialDialectsof Emotion in Four Different National Cultures
2021
The theory of universal emotions suggests that certain emotions such as fear, anger, disgust, sadness, surprise and happiness can be encountered cross-culturally. These emotions are expressed using specific facial movements that enable human communication. More recently, theoretical and empirical models have been used to propose that universal emotions could be expressed via discretely different facial movements in different cultures due to the non-convergent social evolution that takes place in different geographical areas. This has prompted the consideration that own-culture emotional faces have distinct evolutionary important sociobiological value and can be processed automatically, and …
“If you compress the spring, it will snap back hard”: The Ukrainian crisis and the balance of threat theory
2014
The narrative of an aggressive and neo-imperialist Russia that has dominated analyses of the 2014 Ukrainian crisis lacks theoretical rigour. We argue that a sustainable transformation of the Ukrainian crisis requires an accurate analysis of the context of the conflict, which should include an understanding of Moscow’s perception of the threats to its interests. This policy brief develops a theoretical understanding of the Ukrainian crisis through the lens of Stephen M. Walt’s balance of threat theory. We conclude that a realist analysis will help to explain Russian actions.
Corrigendum: Quality of the Physical Education Teacher's Instruction in the Perspective of Self-Determination
2021
The teacher’s instructions in physical education class have important implications for the psychological well-being of their students. The aim of this study was to analyze, under the postulates of the Self-Determination Theory (SDT), a model with the following sequence: the perception of the quality of the instructions (task presentation, amount of corrective feedback, and its legitimate perception) generated by the physical education teacher, the satisfaction of the three basic psychological needs and the subjective vitality in young students. The participants were 890 students (462 males and 428 females) of primary level from the metropolitan area of Monterrey, Mexico, between ages 11 and…
Students’ Perceptions of Teachers’ Corrective Feedback, Basic Psychological Needs and Subjective Vitality: A Multilevel Approach
2020
The way students perceive corrective feedback has repercussions on what they learn and think. Based on the self-determination theory, the aim of this study is to test a model of multilevel mediation that examines the relationships between the perception of corrective feedback with its degree of acceptance (perceived legitimacy) at the team level and the subjective vitality of students at the individual level, mediated by the satisfaction of the three psychological needs, in the context of physical education. The participants were 742 students aged between 10 and 13 years old (52.6% men, 47.4% women) in 29 physical education groups. The results of the multilevel structural equation modeling …
19F-MRI of perflubron for measurement of oxygen partial pressure in porcine lungs during partial liquid ventilation
2001
A method for in vivo measurement of oxygen partial pressure (pO2) in porcine lungs during partial liquid ventilation (PLV) with perflubron (PFOB) was developed. A pulse sequence for high-resolution MRI of the distribution of PFOB in the lung after intratracheal administration was developed as well. Moreover, quantitative measurements of longitudinal relaxation time T(1) of (19)F resonances for assessment of regional pO2 are described. Due to the need to acquire data during a single expiratory breathhold, only low SNRs were achieved in vivo. Therefore, simulations were performed to investigate the influence of background noise on T(1) values calculated from data with low SNR. Based on these …
Self-reported symptoms in women with diastasis rectus abdominis: A systematic review
2021
Abstract Introduction Diastasis rectus abdominis (DRA) diagnosis via clinical examination is well defined, however, the assessment of symptoms has been less investigated. Currently, there is also scant knowledge on the consequences of DRA. The aim of this review is to identify the relevant self-reported variables in the study of DRA in women. Methods We performed a systematic review of observational studies through Medline, Embase, and Cochrane Library databases. Studies evaluating the link between DRA and self-reported symptoms were searched using the following terms: "Diastasis rectus abdominis", "Diastasis recti", "Abdominis Rectus Muscle Diastasis", "Questionnaire", "Scale", "Survey", "…
Outcome comparison among working adults with centralizing low back pain: Secondary analysis of a randomized controlled trial with 1-year follow-up
2009
Our purpose was to examine if adults with centralizing pain might achieve better treatment outcomes when treated by individually designed therapy than “given advice only to stay active”. One hundred and nineteen working adults with first or a recurrent episode of low back pain (LBP) were classified as centralizers and were randomly allocated to orthopaedic manual therapy (OMT; n=42), the McKenzie (n=48) or “advice only to stay active” (Advice-only; n=29) groups. Back and leg pain were assessed by the visual analogue scale, disability with the Roland–Morris questionnaire and functional status with an activities of daily living (ADL) index. Immediately after the treatment period, LBP decrease…
Emergency surgery in a patient with large spontaneous spinal epidural hematoma determining excellent neurological recovery: Review of the literature
2014
Study design: Case report. Objectives: We report a case of a 75-year-old woman suffering from voluminous idiopathic spontaneous spinal epidural hematoma (SSEH) that was rapidly diagnosed and successfully treated. Methods: Clinical presentation was characterized by sudden and intense back pain that rapidly evolved into plegia of the right leg and severe paresis of the left leg. Hypoesthesia below T6 and urinary retention were also present. Magnetic resonance imaging showed a significant posterior spinal compression from T6 through L3 caused by an epidural hematoma that involved 10 metameric levels, extending for ∼20 cm, with a maximum thickness of 1.6 cm from T12 to L1. Results: Within 12 h,…
