    Near Vertical Incidence Skywave propagation measurements duplicated in Spain and The Netherlands

    (Report on a completed Short-Term Scientific Mission (STSM) funded by EurAAP) The ionosphere – under influence of the earth magnetic field – splits linearly polarized waves into two circularly polarized waves with opposite rotation sense [1]: magneto-ionic propagation. Our previous empirical NVIS research [2-4] has shown that that two orthogonal (physical) propagation channels can be created using dual circular polarization antennas, potentially doubling channel capacity. All previous measurements where performed on a 110 km long North-South path in The Netherlands (53ºN). To prove that the concept is not limited to specific azimuth angles and distances, the following experiment was designed: Multiple (4-8) beacon transmitters are set-up at random azimuth angles and random distances between 50 and 200 km around a single receiver site, the transmitters operating at a frequency around 7 MHz. Each beacon switches between Right Hand Circular Polarization (RHCP), Left hand Circular Polarization (LHCP) and linear polarization every 12 seconds. The signal of all beacons is recorded using a high-end digital receiver with 2 coherent antenna inputs, connected to two orthogonal dipoles. From this raw data, simultaneous reception of RHCP, LHCP and linear polarizations can be created. Isolation between the LHCP and RHCP channels will be calculated for each instant in time. The experiment is considered successful when more than 20 dB isolation is achieved. Possible improvement with adaptive elliptical polarization will be studied. Also the fading on the RHCP, LHCP and linearly polarized signals will be characterized and compared. The vertical angle of the earth’s magnetic field – which depends on the latitude of the location – is of influence on the magneto-ionic propagation. To prove that the experiment latitude is not critical to our earlier results, the experiment is first performed in The Netherlands (53ºN), then duplicated in Spain (41ºN), with the assistance of experts of the La Salle Ramon Llull University of Barcelona. Travel and lodging costs for this cooperation are sponsored by the European Association on Antennas and Propagation (EurAAP) through their Short-Term Scientific Mission (STSM) program, which stimulates cooperation between propagation experts of different European countries

    It Will Take a Global Movement to Curb Corruption in Health Systems; Comment on “We Need to Talk About Corruption in Health Systems”

    Corruption in health systems is a problem around the world. Prior research consistently shows that corruption is detrimental to population health. Yet public health professionals are slow to address this complicated issue on a global scale. In the editorial entitled “We Need to Talk About Corruption in Health Systems” concern with the general lack of discourse on this topic amongst health professionals is highlighted. In this invited commentary three contributing factors that hamper public dialogue on corruption are discussed. These include (i) corrupt acts are often not illegal, (ii) government and medical professionals continued acceptance of corruption in the health systems, and (iii) lack of awareness within the general public on the extent of the problem. It is advocated that a global movement that is fully inclusive needs to occur to eradicate corruption

    The impact of virtual learning on health literacy: lessons from a virtual townhall held by the Lamar University Recovery and Resilience Academy

    Background: The COVID-19 pandemic shut down the entire world. This caused universities and addiction recovery programs to get creative on how to reach community needs. Many professors found themselves teaching online for the first time. Apps for mental health and addiction recovery programs grew exponentially. Information on how adequate virtual programs perform are mixed. We investigate the extent to which a virtual program can increase health literacy. To accomplish this, the professors of the sociology program launched the Recovery and Resilience Academy (RnR Academy). The aim of RnR Academy is to serve as an outreach and educational center for the people of Southeast Texas who want to learn how to be better prepared to overcome adversity. Methods: In March 2022, the Mayor of Beaumont, TX along with professors from the sociology program at Lamar University led a virtual townhall. The aim of the townhall was to teach the community about invisible illnesses. Invisible illnesses are related to sicknesses that are not visible to the human eye. For example, chronic pain, mental health and addictions are some of the many illnesses that fall under the invisible illness category. In the townhall held by RnR Academy, health topics included mental health, chronic Lyme disease, long COVID, and health related problems from living in mold invested housing. The townhall was 100% virtual. Members of the local community were invited to complete a pre-test (n=48), following this they watched four 10-minute presentations, and after the presentations completed a post-test (n=33). Results: Results for all health indicators suggest that health literacy slightly increased. For example, results showed that before community members watched the presentations, only 77.1% had ever heard of long COVID. After watching the presentation, 100% report knowing that COVID-19 can last more than 1-year. Conclusions: Preliminary findings suggest that even though people are historically accustomed to face-to-face instruction, virtual learning can produce positive outcomes. Rural communities and other hard to reach populations that cannot attend face-to-face meetings might benefit from virtual health education programs. Given that many local programs in rural communities have small numbers or limited access to larger refined programs, launching a virtual education program could be a huge win for addiction recovery programs and initiatives aimed at reducing health disparities
