Mindfulness Training and Classroom Behavior Among Lower-Income and Ethnic Minority Elementary School Children

This field intervention trial evaluated the effect of a 5-week mindfulness-based curriculum on teacher-ratings of student classroom behavior at a Richmond, CA public elementary school, and examined if the addition of more sessions provided added benefit to student outcomes. Seventeen teachers reported on the classroom behaviors of 409 children (83 % enrolled in a California free lunch program and 95.7 % ethnic minority) in kindergarten through sixth grade at pre-intervention, immediate post-intervention, and 7 weeks post-intervention. Results showed that teachers reported improved classroom behavior of their students (i.e., paying attention, self-control, participation in activities, and caring/respect for others) that lasted up to 7 weeks post-intervention. Overall, improvements were not bolstered by the addition of extra sessions, with the exception of paying attention. The implications of this study are limited due to the lack of a mindfulness program-naïve control group, yet findings suggest that mindfulness training might benefit teacher-based perceptions of improved classroom behavior in a public elementary school, which has practice implications for improving the classroom learning environment for lower-income and ethnically-diverse children.     

Estructura social y conductas de saludo en dos especies de babuinos

Resumen

Independientemente de la proximidad taxonómica, dentro del género Papio existen distintas formas de estructura social. Al mismo tiempo se encuentran diferencias cuantitativas y cualitativas en los repertorios de conducta de las dos especies estudiadas (P. hamadryas y P. cynocephalus), concretamente en los movimientos de salutación.

Se buscó una relación entre dichas estructuras sociales y los respectivos movimientos de saludo que aparecían como característicos de cada especie. La estructura social podría modificarse rápidamente por las presiones ambientales, por lo que serían necesarios nuevos repertorios conductuales en consonancia con el cambio y al mismo tiempo que éste.

Al menos en niveles tan altos de la escala evolutiva, los individuos son capaces de organizar sus conductas según su posición respecto al conjunto del grupo y adecuarlas para acceder a los distintos nichos sociales. Por tanto, no es posible adscribir a la conducta una función exclusiva, sino que dependería de la idiosincrasia individual y de los distintos escalones sociales característicos de una determinada estructura social.     

Cross-cultural generalizability of the Personality and Role Identity Structural Model (PRISM): Implications for trait and cultural psychology

The cross-cultural generalizability of the Personality and Role Identity Structural Model (PRISM; Wood & Roberts, 2006) was tested in the United States, Mexico, Malaysia, China, and Japan. Participants rated their general and role identities, as defined by the PRISM, using Big Five trait adjectives, then rated their personality states (i.e., role experiences) in various roles in multiple daily interactions for 14 days. Structural predictions based on the PRISM were supported in all five cultures. Cultural differences were limited and did not reflect cultural differences in individualism–collectivism, dialecticism, or cultural tightness. The results supported the cross-cultural generalizability of the PRISM and the merits of contextualized trait measures in the prediction of role experiences. Implications for trait and cultural psychology are discussed.     

Larger plantar flexion torque variability implies less stable balance in the young: An association affected by knee position

The present study examined the association between plantar flexion torque variability during isolated isometric contractions and during quiet bipedal standing. For plantar flexion torque measurements in quiet stance (QS), subjects stood still over a force plate. The mean plantar flexion torque level exerted by each subject in QS (divided by 2 to give the torque due to a single leg) served as the target torque level for right leg force-matching tasks in extended knee (KE) and flexed knee (KF) conditions. Muscle activation levels (EMG amplitudes) of the triceps surae and mean, standard deviation and coefficient of variation of plantar flexion torque were computed from signals acquired during periods with and without visual feedback. No significant correlations were found between EMG amplitudes and torque variability, regardless of the condition and muscle being analyzed. A significant correlation was found between torque variability in QS and KE, whereas no significant correlation was found between torque variability in QS and KF, regardless of vision availability. Therefore, torque variability measured in a controlled extended knee plantar flexion contraction is a predictor of torque variability in the anterior-posterior direction when the subjects are in quiet standing. In other words, larger plantar flexion torque variability in KE (but not in KF) implies less stable balance. The mechanisms underlying the findings above are probably associated with the similar proprioceptive feedback from the triceps surae in QS and KE and poorer proprioceptive feedback from the triceps surae in KF due to the slackening of the gastrocnemii. An additional putative mechanism includes the different torque contributions of each component of the triceps surae in the two knee angles. From a clinical and research standpoint, it would be advantageous to be able to estimate changes in balance ability by means of simple measurements of torque variability in a force matching task.     

Syndromes or symptoms in the assessment of aphasic patients?

The procedure generally used to diagnose aphasic patients consists of classifying them in one of the classic syndromes on the basis of the analysis of their symptoms. However, this taxonomy has several important problems, the main one being that it does not take into account the variability of aphasic patients, as there are many more disorder profiles than those included in the syndromes. In order to test the homogeneity of a sample of patients diagnosed with the classic taxonomy, 15 aphasic patients (5 Broca, 5 Wernicke and 5 Conduction) and 5 healthy controls were tested with nine comprehension and production tasks. Participants were aged 38 to 81 years old. The results indicate the existence of great variability in patients labeled with the same diagnosis, as revealed by the differences in within-group scores in each task, and a limited adjustment to the expected profile, with some patients showing symptoms allegedly corresponding to other syndromes. Our results call attention to the need to study each patient individually and interpret their disorders regardless of the syndromes.     

Professional Journeys of International Medical Graduates in Quebec: Recognition,Uphill Battles,or Career Change

In Quebec and Canada, immigration policies are designed to attract “the best and the brightest.” Once migration occurs, however, the “brain waste” is challenging. This research focuses on the professional trajectories of international medical graduates (IMG) who migrate to Quebec. The main goal is to understand why certain individuals of a similar occupational group can easily access the doctoral profession while others cannot. Following a qualitative approach, and stemming from IMGs’ perspectives, this article explores the interplay of economic, social, and symbolic resources in a context of highly fragmented institutional resources and protectionism. We are critical of the individual-centered approaches that ignore social norms and constraints. If migrants are free to choose their paths and manner of integration, the “human capital” approach is limited in explaining the heterogeneous pathways within the same professional group. The current structure for professional recognition places unusual constraints on IMGs, whereby some encounter more obstacles than others. The “battle” for professional recognition takes shape in a highly competitive context, one which—although presented as a neutral process—is underlain with ideological, relational, and subjective currents.     

From an Existentialist God to the God of Existence. The Theological Conjectures of Hans Jonas

Hans Jonas developed in ‘Past and Truth’ (1991) a demonstration of the existence of God based on the ‘truth of past things’. And in ‘The Concept of God after Auschwitz’ (1984) he created a new myth of divine self-alienation in order to take away God’s responsibility for human misery. Both these texts were conceived as an alternative to a more Hegelian, objective idealist perspective on theology. This article shows that Jonas’s alternative does not fully succeed in this respect because his arguments bring him back to an idealist perspective. His proof of God is revisited and explained using new insights recently developed by Robert Spaemann, whose interpretation of the proof makes it clear that many important critics of Jonas are too quick to reject his claims. The arguments of Jonas now seem to show a new strength even though they still fail to give an alternative to an objective idealist theological framework.     

Relational and imageric recall in young and older adults under conditions of high task demand

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction, has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively circumscribed and specific. This research was supported by grant AG11605 from the National Institute on Aging, and by a grant from the College of Science and Mathematics, California State University.     

The use of indigenous interviewers in a study of latino men who have sex with men: A research note

The use of indigenous researchers has long been practiced in ethnographic research; a similar use of indigenous personnel has not been as commonly undertaken in interview studies of men who have sex with men (MSM). This research note reports on the use of indigenous interviewers in a study of Latino MSM’s perceptions about sexual relationships and behaviors. The full study explores sexual relationships among Latino MSM, and HIV risk behaviors undertaken by a population of MSM residing in a community in southern California. This research note describes both the strengths and limitations that arise from employing indigenous interviewers for improving the overall quality of sensitive data. Benefits discussed include improved access to an otherwise highly restricted group, enhanced rapport-building capabilities, and greater understanding of language unique to the study population. Limitations discussed include the use of previously untrained interview personnel and age and gender issues.     

Intra-amygdala ZIP injections impair the memory of learned active avoidance responses and attenuate conditioned taste-aversion acquisition in rats

We have investigated the effect of protein kinase Mzeta (PKMζ) inhibition in the basolateral amygdala (BLA) upon the retention of a nonspatial learned active avoidance response and conditioned taste-aversion (CTA) acquisition in rats. ZIP (10 nmol/μL) injected into the BLA 24 h after training impaired retention of a learned avoidance-jumping response assessed 7 d later when compared with control groups injected with scrambled-ZIP. Nevertheless, a retraining session applied 24 h later indicated no differences between the groups. Additionally, a similar ZIP injection into the BLA during the conditioned stimulus-unconditioned stimulus (CS-US) interval attenuated CTA acquisition. These findings support the BLA PKMζ role in various forms of memory.
