Effects of meditation experience on functional connectivity of distributed brain networks

This study sought to examine the effect of meditation experience on brain networks underlying cognitive actions employed during contemplative practice. In a previous study, we proposed a basic model of naturalistic cognitive fluctuations that occur during the practice of focused attention meditation. This model specifies four intervals in a cognitive cycle: mind wandering (MW), awareness of MW, shifting of attention, and sustained attention. Using subjective input from experienced practitioners during meditation, we identified activity in salience network regions during awareness of MW and executive network regions during shifting and sustained attention. Brain regions associated with the default mode were active during MW. In the present study, we reasoned that repeated activation of attentional brain networks over years of practice may induce lasting functional connectivity changes within relevant circuits. To investigate this possibility, we created seeds representing the networks that were active during the four phases of the earlier study, and examined functional connectivity during the resting state in the same participants. Connectivity maps were then contrasted between participants with high vs. low meditation experience. Participants with more meditation experience exhibited increased connectivity within attentional networks, as well as between attentional regions and medial frontal regions. These neural relationships may be involved in the development of cognitive skills, such as maintaining attention and disengaging from distraction, that are often reported with meditation practice. Furthermore, because altered connectivity of brain regions in experienced meditators was observed in a non-meditative (resting) state, this may represent a transference of cognitive abilities “off the cushion” into daily life

Building equitable literate futures : home and school computer-mediated literacy practices and disadvantage

This paper examines the complex connections between literacy practices, the use of information and communication technologies (ICTs) and disadvantage. It reports the findings of a year-long study which investigated the ways in which four families use ICTs to engage with formal and informal literacy learning in home and school settings. The research set out to explore what it is about computer-mediated literacy practices at home and at school in disadvantaged communities that make a difference in school success. The findings demonstrate that the \u27socialisation\u27 of the technology - its appropriation into existing family norms, values and lifestyles - varied from family to family. Having access to ICTs at home was not sufficient for the young people and their families to overcome the so-called \u27digital divide\u27. Clearly, we are seeing shifts in the meaning of \u27disadvantage\u27 in a globalised world mediated by the use of new technologies. New definitions of disadvantage that take account not only of access to the new technologies but also include calibrated understandings of what constitutes the access are required. The article concludes that old inequalities have not disappeared, but are playing out in new ways in the context of the networked society.<br /

Chicago Music City

Chicago Music City compares the strength and vitality of music industries and scenes across the United States. Sociologists, urban planners, and real-estate developers point to quality of life and availability of cultural amenities as important indicators of the health and future success of urban areas. Economic impact studies show the importance of music to local economies. This publication compares Chicago's musical strength with the 50 largest metropolitan areas in the U.S., focusing on 11 comparison cities: Chicago and its demographic peers, New York and Los Angeles, and eight other cities with strong musical reputations -- Atlanta, Austin, Boston, Las Vegas, Memphis, Nashville, New Orleans and Seattle

The US Supreme Court’s Rulings on Large Business and Health Care Worker Vaccine Mandates: Ramifications for the COVID-19 Response and the Future of Federal Public Health Protection

On January 13, 2022, the Supreme Court issued 2 landmark rulings on the federal government’s power to mandate COVID-19 vaccinations. The Court curtailed the government’s ability to respond to the pandemic and may have also severely limited the authority of federal agencies to issue health and safety regulations. In National Federation of Independent Business v Department of Labor, the Court blocked an Occupational Safety and Health Administration (OSHA) emergency temporary standard (ETS) requiring vaccination, subject to religious or disability accommodations, or weekly testing and masking in businesses with 100 or more employees. In Biden v Missouri, the Court upheld a Centers for Medicare & Medicaid Services (CMS) regulation mandating health worker vaccinations, subject to the same accommodations. What do these decisions reveal about the future of federal protection of public health and safety

Validating the Psychological Climate Scale in Voluntary Child Welfare

Objective: Organizational climate has emerged as an important factor in understanding and addressing the complexities of providing services in child welfare. This research examines the psychometric properties of each of the dimensions of Parker and colleagues’ Psychological Climate Survey in a sample of voluntary child welfare workers. Methods: Confirmatory factor analysis was utilized to analyze data on 640 child welfare workers providing services directly to children and families. Results: Strong models were developed for each dimension. Each validated model was more parsimonious than in the original instrument but supported the theoretical underpinnings of each. Discussion and Applications to Social Work: Psychological climate in voluntary child welfare agencies can be assessed along each of four dimensions identified by Parker and colleagues: job, role, organization, and supervision. Those wishing to examine psychological climate in voluntary child welfare settings should consider using the models identified in the current research

Evidence-informed process to identify policies that will promote a healthy food environment in the Pacific Islands

Objective: To implement a systematic evidence-informed process to enable Fiji and Tonga to identify the most feasible and targeted policy interventions which would have most impact on diet-related non-communicable diseases.Design: A multisectoral stakeholder group of policy advisers was formed in each country. They used participatory approaches to identify the problem policies and gaps contributing to an unhealthy food environment. Potential solutions to these problems were then identified, and were assessed by them for feasibility, effectiveness, cost-effectiveness and side-effects. Data were gathered on the food and policy environment to support the assessments. A shortlist of preferred policy interventions for action was then developed.Results: Sixty to eighty policy problems were identified in each country, affecting areas such as trade, agriculture, fisheries and pricing. Up to 100 specific potential policy solutions were then developed in each country. Assessment of the policies highlighted relevant problem areas including poor feasibility, limited effectiveness or cost-effectiveness and serious side-effects. A shortlist of twenty to twenty-three preferred new policy options for action in each country was identified.Conclusions: Policy environments in these two countries were not conducive to supporting healthy eating. Substantial areas of potential action are possible, but some represent better choices. It is important for countries to consider the impact of non-health policies on diets.<br /

The Impact of Gallium Content on Degradation, Bioactivity, and Antibacterial Potency of Zinc Borate Bioactive Glass

Zinc borate glasses with increasing gallium content (0, 2.5, 5, 10, and 15 Wt % Ga) were synthesized and their degradation, bioactivity in simulated body fluid (SBF), and antibacterial properties were investigated. ICP measurements showed that increased gallium content in the glass resulted in increased gallium ion release and decreased release of other ions. Degradability declined with the addition of gallium, indicating the formation of more symmetric BO3 units with three bridging oxygens and asymmetric BO3 units with two bridging oxygens in the glass network as the gallium content in the series increased. The formation of amorphous Ca-P on the glass surface after 24 h of incubation in SBF was confirmed by SEM, XRD, and FTIR analyses. Finally, antibacterial evaluation of the glasses using the agar disc-diffusion method demonstrated that the addition of gallium increased the antibacterial potency of the glasses against P. aeruginosa (Gram-negative) while decreasing it against S. epidermidis (Gram-positive); considering the ion release trends, this indicates that the gallium ion is responsible for the glasses\u27 antibacterial behavior against P. aeruginosa while the zinc ion controls the antibacterial activity against S. epidermidis. The statistical significance of the observed trends in the measurements were confirmed by applying the Kruskal-Wallis H Test. © 2017 Wiley Periodicals, Inc.
