Mindfulness-based meditation practices involve various attentional skills, including the ability to sustain and focus ones attention. During a simple mindful breathing practice, sustained attention is required to maintain focus on the breath while cognitive control is required to detect mind wandering. We thus hypothesized that regular, brief mindfulness training would result in improvements in the self-regulation of attention and foster changes in neuronal activity related to attentional control. A longitudinal randomized control group EEG study was conducted. At baseline (T1), 40 meditation naïve participants were randomized into a wait list group and a meditation group, who received three hours mindfulness meditation training. Twenty-eight participants remained in the final analysis. At T1, after eight weeks (T2) and after 16 weeks (T3), all participants performed a computerized Stroop task (a measure of attentional control) while the 64-channel EEG was recorded. Between T1 and T3 the meditators were requested to meditate daily for 10 min. Event-related potential (ERP) analysis highlighted two between group effects that developed over the course of the 16-week mindfulness training. An early effect at left and right posterior sites 160–240 ms post-stimulus indicated that meditation practice improved the focusing of attentional resources. A second effect at central posterior sites 310–380 ms post-stimulus reflects that meditation practice reduced the recruitment of resources during object recognition processes, especially for incongruent stimuli. Scalp topographies and source analyses (Variable Resolution Electromagnetic Tomography, VARETA) indicate relevant changes in neural sources, pertaining to left medial and lateral occipitotemporal areas for the early effect and right lateral occipitotemporal and inferior temporal areas for the later effect. The results suggest that mindfulness meditation may alter the efficiency of allocating cognitive resources, leading to improved self-regulation of attention.
In a world where information technology is both important and imperfect, organizations and individuals are faced with the ongoing challenge of determining how to use complex, fragile systems in dynamic contexts to achieve reliable outcomes. While reliability is a central concern of information systems practitioners at many levels, there has been limited consideration in information systems scholarship of how firms and individuals create, manage, and use technology to attain reliability. We propose that examining how individuals and organizations use information systems to reliably perform work will increase both the richness and relevance of IS research. Drawing from studies of individual and organizational cognition, we examine the concept of mindfulness as a theoretical foundation for explaining efforts to achieve individual and organizational reliability in the face of complex technologies and surprising environments. We then consider a variety of implications of mindfulness theories of reliability in the form of alternative interpretations of existing knowledge and new directions for inquiry in the areas of IS operations, design, and management.

Researchers are increasingly exploring how neighborhood greenness, or vegetation, may affect health behaviors and outcomes. Greenness may influence health by promoting physical activity and social contact; decreasing stress; and mitigating air pollution, noise, and heat exposure. Greenness is generally measured using satellite-based vegetation indices or land-use databases linked to participants’ addresses. In this review, we found fairly strong evidence for a positive association between greenness and physical activity and a less consistent negative association between greenness and body weight. Research suggests greenness is protective against adverse mental health outcomes, cardiovascular disease, and mortality, though most studies were limited by cross-sectional or ecological design. There is consistent evidence that greenness exposure during pregnancy is positively associated with birth weight, though findings for other birth outcomes are less conclusive. Future research should follow subjects prospectively, differentiate between greenness quantity and quality, and identify mediators and effect modifiers of greenness-health associations.

Various arguments are reviewed about the claim that language development is critically connected to the development of theory of mind. The different theories of how language could help in this process of development are explored. A brief account is provided of the controversy over the capacities of infants to read others' false beliefs. Then the empirical literature on the steps in theory of mind development is summarized, considering studies on both typically developing and various language-delayed children. Suggestions are made for intervention by speech language pathologists to enhance the child's access to understanding the minds of others.
Far-reaching changes to the structure and function of the Earth's natural systemsrepresent a growing threat to human health. And yet, global health has mainly improved
as these changes have gathered pace. What is the explanation? As a Commission, we
are deeply concerned that the explanation is straightforward and sobering: we have
been mortgaging the health of future generations to realise economic and development
gains in the present. By unsustainably exploiting nature's resources, human civilisation
has flourished but now risks substantial health effects from the degradation of nature's
life support systems in the future.

Sangye Gyatso played a major role in the politics of 17th century Tibet, and was the originator of the medical paintings that encompassed the full scope of Tibetan medicine.The depictions became an important aid in medical education, and was heavily influenced by Buddhist thinking. The paintings arose in a visual culture dominated by religious art.
<p>The article gives an account of shamanism in Nepal, particularly among the Tamang. The major social functions of the shaman in Tamang society is the diagnosis and treatment of illness. This article's main purposes are to investigate the indigenous categories of illness and examine the unique relationship that exists between modern medicine and shamanism in the Kathmandu valley of Nepal. It discusses the traditional categories of illness, like Lagu, and healing rituals, such as puja. It discusses the socio-psychology of the healing ritual practiced by Tamang shamans. The author argues that the shaman can even come to help spread medical aid in as much as they already recognize their own limitations in the treating of certain illness and take an active part in getting their clients to seek such treatment. Shamanism is not inherently antithetical to modern medicine. (Rajeev Ranjan Singh 2007-01-17)</p>
Mindfulness meditation is thought to lead to positive changes in cognitive and affective functioning. However, the mechanisms underlying these changes are not well understood. One reason for this is that so far only very few studies considered the effects of specific meditation practices. We thus investigated the effects of engaging in one specific form of mindfulness meditation for a brief time period on behavioral and neural indicators of inhibitory control and metacognition. Performance on the Go/No-Go task and concurrent neural activity (EEG) was assessed before and after participants engaged in 3 weeks of mindful breath awareness meditation. Compared to a waitlist control group, meditation training enhanced the N2 event-related potential in No-Go trials and the error-related negativity (ERN) after error responses. As these two components reflect conflict and response monitoring, respectively, our results support the notion that mindfulness meditation improves metacognitive processes. The changes in the ERN were correlated with the accumulated amount of meditation time, highlighting the importance of meditation practice. Furthermore, meditation improved a behavioral marker of impulsive responding, indicating the relevance of mindfulness-based approaches for supporting health-related behaviors that are associated with deficits in impulsive control, such as substance abuse or over-eating. This study demonstrated that investigating one particular meditation practice rather than complex mindfulness-based interventions can contribute to a deeper understanding of mindfulness meditation mechanisms.
This article draws on a study which investigated the interpretation and use of Social and Emotional Aspects of Learning (SEAL) in primary schools in the UK (the authors gratefully acknowledge Studentship funding from the Economic and Social Research Council for this study). The paper focuses on school staff members' perceptions about the intentions and purposes of the scheme. The testimonies of head teachers, management staff, teachers, teaching assistants, welfare assistants and pastoral staff members illustrated how the interpretation and use of SEAL was influenced by their perceptions about the pupils' parents and, in particular, parental ability to develop 'appropriate' social, emotional and behavioural skills in their children. In schools where parenting was positively appraised, SEAL was used to complement parenting practices; whilst in schools where parents were negatively appraised, SEAL was used to counter their endeavours. The scheme was also used to compensate for certain inadequacies that were deemed to be taking place in the home. These differing perceptions of parents were linked to social class, with the scheme being used to complement the practices of middle-class parents and to counter those of minority-ethnic and working-class people. We contend that this interpretation and use of the scheme helped to re-affirm the practices of the dominant culture whilst serving to marginalise the values of the less powerful groups in society. Implications of the study's findings are discussed and recommendations for staff, schools and policy are made.
A key challenge for 21st-century schools, families, and communities is to develop knowledgeable, responsible, and caring students who are able to work well with others from diverse backgrounds in socially and emotionally skilled ways. This case study tells the story of one middle school's journey through the implementation of a social and emotional learning (SEL) initiative. The study highlights key factors that contributed to the program's initiation, successes and challenges, lessons learned, and implications for school, district, and community leaders. Teacher acceptance, creative scheduling, ongoing evaluation, and leadership support were all important components of program implementation. Although not a panacea, the authors believe it is time for more schools, especially middle schools, to accentuate SEL and embrace a culture that emphasizes the whole child.
The need for improved well-being of children in Britain has been highlighted in a raft of reports both nationally and internationally. In this paper, I aim to explore some of the practicalities experienced by schools that, in response, have implemented social and emotional learning (SEL) interventions as a means to improve child well-being. I make the case that the discourses of emotions inherent within such schemes, and the various supranational publications, are susceptible to exploitation and manifestation. The study employed a mixed methodological approach, utilising a combination of quantitative and qualitative strategies with primary school staff members including head teachers, teachers, teaching assistants, welfare staff, other support staff, etc. Three phases of study--questionnaires, focus groups and individual interviews--were administered as a means of creating an insight into the interpretation and use of SEL in these settings. The findings demonstrate a propensity for staff to conflate social and emotional aspects of self with more moralistic constructs of identity, revealing how SEL schemes have the potential to act as tools of cultural imperialism by marginalising and/or endorsing certain values, norms and behaviours. After maintaining that such realisations of these schemes may impede rather than improve the lived experiences of children, that are fundamental to their social and emotional well-being and mental health, I make the case for alternative approaches to SEL in schools.

Physical inactivity is an important risk factor for cardiovascular mortality and morbidity. Exercise is considered an acceptable method for improving and maintaining physical and emotional health. Although yoga is historically a spiritual discipline, a growing body of evidence supports the belief that yoga benefits physical and mental health. The objective of this study was to evaluate heart rate variability which reflects autonomic control of heart among yoga practitioners, athletes and individuals with sedentary lifestyle. The study was carried out in the departments of physiology at MAMC Agroha, Hisar and Pt. BD Sharma PGIMS Rohtak, Haryana. The study group comprised of 1200 healthy male volunteers of 16 to 55 years of age. The study group was divided into four age groups: Group A of age 16 to 25 years; Group B of age 26 to 35 years; Group C of age 36 to 45 years and Group D of age 46 to 55 years. All age groups were further divided into three categories i.e athlete (runner), yoga (yoga practitioners) and sedentary in which individuals with sedentary life style were included. The basal recording of ECG in lead II was done for 5 minutes. The Polyrite-D ECG data was used for analysis of heart rate variability by frequency domain method. Two spectral components were recorded namely high frequency (HF) component (0.15-0.4 Hz), an indicator of vagal efferent activity and low frequency (LF) component (0.04-.15 Hz), replicator of composite sympatho-vagal interplay. HF component in normalized unit was found significantly high in age group B and C in yoga practitioners and athletes as compared to sedentary individuals and in age group D significantly high in yoga practitioners as compared to athletes and sedentary individuals. Significantly decreased LF/HF ratio was found in age group B and C in yoga and athlete subjects as compared to sedentary individuals and in age group D in yoga practitioners as compared to athletes and sedentary individuals. This indicates that parasympathetic activity is substantially greater in yoga practitioners.
INTRODUCTION: Post-traumatic stress disorder (PTSD) is a debilitating, highly prevalent condition. Current clinical practice guidelines recommend trauma-focused psychotherapy (eg, cognitive processing therapy; CPT) as the first-line treatment for PTSD. However, while these treatments show clinically meaningful symptom improvement, the majority of those who begin treatment retain a diagnosis of PTSD post-treatment. Perhaps for this reason, many individuals with PTSD have sought more holistic, mind-body, complementary and integrative health (CIH) interventions. However, there remains a paucity of high-quality, active controlled efficacy studies of CIH interventions for PTSD, which precludes their formal recommendation.METHODS AND ANALYSES: We present the protocol for an ongoing non-inferiority parallel group randomised controlled trial (RCT) comparing the efficacy of a breathing meditation intervention (Sudarshan Kriya Yoga [SKY]) to a recommended evidence-based psychotherapy (CPT) for PTSD among veterans. Assessors are blinded to treatment group. The primary outcome measure is the PTSD Checklist-Civilian Version and a combination of clinical, self-report, experimental and physiological outcome measures assess treatment-related changes across each of the four PTSD symptom clusters (re-experiencing, avoidance, negative cognitions or mood and hyperarousal/reactivity). Once the RCT is completed, analyses will use both an intent-to-treat (using the 'last observation carried forward' for missing data) and a per-protocol or 'treatment completers' procedure, which is the most rigorous approach to non-inferiority designs.
ETHICS AND DISSEMINATION: To the best of our knowledge, this is this first non-inferiority RCT of SKY versus CPT for PTSD among veterans. The protocol is approved by the Stanford University Institutional Review Board. All participants provided written informed consent prior to participation. Results from this RCT will inform future studies including larger multi-site efficacy RCTs of SKY for PTSD and other mental health conditions, as well as exploration of cost-effectiveness and evaluation of implementation issues. Results will also inform evidence-based formal recommendations regarding CIH interventions for PTSD.
