Is the deinstitutionalisation of alternative care a ‘wicked problem’? A qualitative study exploring the perceptions of child welfare practitioners and policy actors in Thailand
This study examined deinstitutionalisation in Thailand. Qualitative interviews were conducted with a total of 27 child welfare practitioners and policy actors to explore their perceptions of Thai alternative care provision. Findings show that participants perceive deinstitutionalisation as a complex policy challenge. Some felt that the institutions were necessary in order to meet demand, while others felt that cultural barriers prevent a shift to family-based approaches, such as foster care. However, data suggest that it would be difficult to characterise deinstitutionalisation as a ‘wicked policy problem’ as participants were hopeful for change, citing increased family- strengthening policies alongside efforts to implement foster care
An Observational Overview of Solar Flares
We present an overview of solar flares and associated phenomena, drawing upon
a wide range of observational data primarily from the RHESSI era. Following an
introductory discussion and overview of the status of observational
capabilities, the article is split into topical sections which deal with
different areas of flare phenomena (footpoints and ribbons, coronal sources,
relationship to coronal mass ejections) and their interconnections. We also
discuss flare soft X-ray spectroscopy and the energetics of the process. The
emphasis is to describe the observations from multiple points of view, while
bearing in mind the models that link them to each other and to theory. The
present theoretical and observational understanding of solar flares is far from
complete, so we conclude with a brief discussion of models, and a list of
missing but important observations.Comment: This is an article for a monograph on the physics of solar flares,
inspired by RHESSI observations. The individual articles are to appear in

High-energy X-rays and gamma-rays from solar flares were discovered just over
fifty years ago. Since that time, the standard for the interpretation of
spatially integrated flare X-ray spectra at energies above several tens of keV
has been the collisional thick-target model. After the launch of the Reuven
Ramaty High Energy Solar Spectroscopic Imager (RHESSI) in early 2002, X-ray
spectra and images have been of sufficient quality to allow a greater focus on
the energetic electrons responsible for the X-ray emission, including their
origin and their interactions with the flare plasma and magnetic field. The
result has been new insights into the flaring process, as well as more
quantitative models for both electron acceleration and propagation, and for the
flare environment with which the electrons interact. In this article we review
our current understanding of electron acceleration, energy loss, and
propagation in flares. Implications of these new results for the collisional
thick-target model, for general flare models, and for future flare studies are
discussed.Comment: This is an article from a monograph on the physics of solar flares,
