Addressing Challenges to the Reliable, Large-Scale Implementation of Effective School Health Education

The long-held priority of teaching young people the knowledge and skills needed for healthy living has recently been diminished in many preK-12 schools. Driven by federal and state priorities, laws, and policies associated with high-stakes testing, instruction in untested subjects has been reduced or eliminated in most schools in order to devote more attention to tested subjects, like reading, math, writing, and science. This article proposes a pathway to ensure that all children are able to learn what society knows about health. To that end, four challenges to the reliable, large-scale implementation of effective school health education are identified: (1) establishing school health education as an undeniable social and cultural priority through improved advocacy; (2) strengthening educational institutions’ capacities to reliably deliver large-scale, high-quality, school-based health education; (3) collaboratively coordinating efforts of health-promoting governmental and nongovernmental organizations that generate thought leadership for school health education; and (4) creating multidisciplinary research capacities for solving problems associated with the implementation of reliable, large-scale, effective school health education. By implementing specific strategies associated with each challenge, health educators can promote the social and system-level conditions required to support, elevate, and ensure delivery of effective health education to every student in every school every year

Attitudes of Graduating Health Practitioners Toward Older Persons in Ghana

Purpose: This study examined attitudes of graduating medical and nursing students toward older persons in Ghana. The association between the overall quality of students’ experiences with older persons and their attitudes was also examined to identify educational interventions to increase interest in geriatrics. Materials and Methods: A sample of 135 final year medical and nursing students from a public institution in Ghana participated in a cross-sectional study by completing a web-based self-administered questionnaire consisting of the 14-item University of California at Los Angeles Geriatric Attitudes (UCLA-GA) scale and demographic questions. Data analysis involved a two-sample t-test and a one-way ANOVA. Results: Overall, most participants (82.2%) held positive attitudes towards older persons. Medical students had significantly more positive attitudes toward older persons (3.50 ± 0.44) than nursing students (3.26 ± 0.38) (t [133] = 3.257, p = .001). The association between students’ attitudes and the quality of their experiences with older persons was significant (F [2, 132] = 7.062, p = .001). Students whose experiences with older persons were negative had the least positive attitudes. Conclusion: Considering the impact of previous experiences with older persons on medical and nursing students’ attitude in Ghana, training to increase interest in geriatrics should include positive clinical and community-based exposure

Mammography Social Support for Women Living in a Midwestern City: Toward Screening Promotion via Social Interactions

Notwithstanding recommendations and interventions, the percentage of 50 – 74-year-old U.S. women who reported having had a mammography in the past two years remained below target coverage. Social interactions may influence mammography rates. To measure characteristics of social interactions in a Midwestern city as they relate to social support for mammography received by women older than 40 years of age. A cross-sectional study was conducted in Bloomington, Indiana, sending mail surveys to 3,000 telephone directory addresses selected by simple random sampling. An anonymous, self-administered, closed-ended, questionnaire with eight checklist items (for demographics) and six multipart semantic differential scale items (for social support), derived from validated instruments, was used. Social support for mammography in women who had undergone regular screening was analyzed using chi-square test and logistic regression. Of 450 respondents with valid responses, 91% were white; 47% were older than 80; 92% had good health insurance coverage; and 82% had undergone regular mammography. Healthcare workers provided the highest support, followed by children, siblings, and relatives. Friends, neighbors, and co-workers were least supportive. In social interactions, emotional support was the most prominent, followed by informational, appraisal, and instrumental supports. Having higher income and being married were associated with receiving greater support. Although mammography provides limited benefits after age 74, women older than 80 years of age received the highest support. Identifying the structural and functional characteristics of social interactions is important for: 1) designing interventions that enhance social support, and 2) expanding breast cancer screening via personalized approaches using existing social interactions

Global Perspectives for Strengthening Health Education: A Mixed-Methods Study

This study aimed to identify the knowledge, experiences, and attitudes about current practices of health education (HE) among government-affiliated high-profile health administrators in developed and developing nations. Respondents (N = 21) were purposively selected based on their affiliation as a health administrator at the national level, with roles in high-profile decision-making for devising policies/programs and allocating funding or advocating strategies to advance HE. Information was gathered using a web-based cross-sectional survey in 5 languages, consisting of 14 closed-ended and 8 open-ended questions. A majority were males (70%) and spoke English (57%), 45% had postgraduate degrees, and 57% were from high-income countries. Participants recognized the importance of HE in their countries and estimated percentages of adults who received health information through various sources. Participants also rated population subgroups that benefit from HE. They highly rated these health issues for HE: control/prevention of communicable diseases, nutrition, physical activity, mental health, and tobacco and other drugs. Only 40% reported having enough resources and funding available for HE. For the qualitative questions, irrespective of being from developed or developing countries, most respondents identified the need for invigorating HE that could be categorized into seven key areas: HE program evaluation, actions to strengthen HE, organizations responsible for identifying HE priorities, job titles of health educators, how ministry collects information on HE needs, high priority health issues and ensuring equity, and ways nongovernmental organizations can strengthen HE. Findings were helpful to identify: high priority HE issues across countries; status of HE programs among government entities; status of funding for HE programs; and how countries can provide more effective program outcomes. Further studies with higher response rate are needed to address these specific issues

Untying the Gordian Knot: The Development of an Immunization Information Exchange

Legislative mandates require the sharing of immunization information among multiple stakeholders. This in turn requires the implementation of interoperable systems across various information systems. A key challenge to system interoperability is the need to integrate healthcare information and processes across different settings. This paper reports work in progress on the development of a student immunization Health Information Exchange (HIE). The system builds on a commercially available platform, appropriately modified on both front and backend, to meet the needs of school health professionals and other stakeholders involved in the production and maintenance of immunization information. We describe the situated change perspective as well as the iterative and incremental development process adopted for the project, and examine some of the lessons learned throughout

Detection of bearing damage by statistic vibration analysis

The condition of bearings, which are essential components in mechanisms, is crucial to safety. The analysis of the bearing vibration signal, which is always contaminated by certain types of noise, is a very important standard for mechanical condition diagnosis of the bearing and mechanical failure phenomenon. In this paper the method of rolling bearing fault detection by statistical analysis of vibration is proposed to filter out Gaussian noise contained in a raw vibration signal. The results of experiments show that the vibration signal can be significantly enhanced by application of the proposed method. Besides, the proposed method is used to analyse real acoustic signals of a bearing with inner race and outer race faults, respectively. The values of attributes are determined according to the degree of the fault. The results confirm that the periods between the transients, which represent bearing fault characteristics, can be successfully detected

Charged-Particle Multiplicity in Proton-Proton Collisions

This article summarizes and critically reviews measurements of charged-particle multiplicity distributions and pseudorapidity densities in p+p(pbar) collisions between sqrt(s) = 23.6 GeV and sqrt(s) = 1.8 TeV. Related theoretical concepts are briefly introduced. Moments of multiplicity distributions are presented as a function of sqrt(s). Feynman scaling, KNO scaling, as well as the description of multiplicity distributions with a single negative binomial distribution and with combinations of two or more negative binomial distributions are discussed. Moreover, similarities between the energy dependence of charged-particle multiplicities in p+p(pbar) and e+e- collisions are studied. Finally, various predictions for pseudorapidity densities, average multiplicities in full phase space, and multiplicity distributions of charged particles in p+p(pbar) collisions at the LHC energies of sqrt(s) = 7 TeV, 10 TeV, and 14 TeV are summarized and compared.Comment: Invited review for Journal of Physics G -- version 2: version after referee's comment

Entanglement demonstration on board a nano-satellite

Global quantum networks for secure communication can be realized using large fleets of satellites distributing entangled photon pairs between ground-based nodes. Because the cost of a satellite depends on its size, the smallest satellites will be most cost-effective. This Letter describes a miniaturized, polarization entangled, photon-pair source operating on board a nano-satellite. The source violates Bell’s inequality with a Clauser–Horne–Shimony–Holt parameter of 2.60±0.06. This source can be combined with optical link technologies to enable future quantum communication nano-satellite missions

SpooQy-1: The First Nano-Satellite to Demonstrate Quantum Entanglement in Space

SpooQy-1 is a 3-unit nanosatellite that was launched into a Low Earth Orbit from the International Space Station on the 17th of June 2019. The spacecraft hosts a scientific payload capable of producing entangled photon-pairs and measuring their polarization in orthogonal bases to perform a Bell test. Since launch, SpooQy-1 has routinely demonstrated the generation and detection of polarization entangled photon-pairs in Space, something that has previously only been demonstrated by the 630kg Micius mission by the Chinese Academy of Sciences. The measured entanglement correlations can violate Bell\u27s inequality with a CHSH parameter value of 2.60±0.06, over operating temperatures of 16 °C to 21.5 °C. These results demonstrate that quantum entanglement can be generated in space on highly resource-constrained platforms. A follow-on 12U mission, developed in partnership with RAL space,will build on this to demonstrate space-to-ground entanglement distribution, which is required for space-based nodes to support global quantum communication networks
