The contemporary landscape of fuel poverty research

A key aim of this special issue has been to showcase the breadth of approaches to fuel poverty research emanating from a growing international community of fuel poverty researchers and in doing so, to promote awareness of the range of disciplinary areas influencing contemporary fuel poverty research. Overcoming established disciplinary and methodological siloes represents a considerable challenge for the future of the field and may be key to offering those in policy and practice the clarity and comprehensive insights that they need to fully understand and respond effectively to the problem

Gyrotropic impact upon negatively refracting surfaces

Surface wave propagation at the interface between different types of gyrotropic materials and an isotropic negatively refracting medium, in which the relative permittivity and relative permeability are, simultaneously, negative is investigated. A general approach is taken that embraces both gyroelectric and gyromagnetic materials, permitting the possibility of operating in either the low GHz, THz or the optical frequency regimes. The classical transverse Voigt configuration is adopted and a complete analysis of non-reciprocal surface wave dispersion is presented. The impact of the surface polariton modes upon the reflection of both plane waves and beams is discussed in terms of resonances and an example of the influence upon the Goos–Hänchen shift is given

Addressing Food Insecurity During COVID-19: A Role for Rural Federally Qualified Health Centers

In rural communities, existing food insecurity, chronic diseases, and an aging population create a complex environment that has the potential to strain health systems despite lower overall COVID-19 case counts. Past pandemics have revealed that populations served by the primary care safety net require resources beyond federal and state aid programs. At our federally qualified health center (FQHC), we have adapted our food prescription program for patients with chronic diseases to a home delivery service, which leverages existing relationships between care coordinators and patients. Such efforts may fill underlying gaps in food supply and distribution through cross-sector collaboration with farms and non-governmental agencies. The current pandemic highlights an opportunity for FQHCs to proactively engage with communities and build upon existing outreach efforts to address issues of nutrition and food access. Prompt and targeted interventions can establish partnerships within community food systems and advance long-term program implementation.https://deepblue.lib.umich.edu/bitstream/2027.42/155450/1/Suresh_Barkatullah_Boardman_PrePrint_Final.pd

Social networks : the future for health care delivery

With the rapid growth of online social networking for health, health care systems are experiencing an inescapable increase in complexity. This is not necessarily a drawback; self-organising, adaptive networks could become central to future health care delivery. This paper considers whether social networks composed of patients and their social circles can compete with, or complement, professional networks in assembling health-related information of value for improving health and health care. Using the framework of analysis of a two-sided network – patients and providers – with multiple platforms for interaction, we argue that the structure and dynamics of such a network has implications for future health care. Patients are using social networking to access and contribute health information. Among those living with chronic illness and disability and engaging with social networks, there is considerable expertise in assessing, combining and exploiting information. Social networking is providing a new landscape for patients to assemble health information, relatively free from the constraints of traditional health care. However, health information from social networks currently complements traditional sources rather than substituting for them. Networking among health care provider organisations is enabling greater exploitation of health information for health care planning. The platforms of interaction are also changing. Patient-doctor encounters are now more permeable to influence from social networks and professional networks. Diffuse and temporary platforms of interaction enable discourse between patients and professionals, and include platforms controlled by patients. We argue that social networking has the potential to change patterns of health inequalities and access to health care, alter the stability of health care provision and lead to a reformulation of the role of health professionals. Further research is needed to understand how network structure combined with its dynamics will affect the flow of information and potentially the allocation of health care resources
