Food practices and nutrition of children and adolescents in residential care: A scoping review.

Food practices of children and adolescents have thus far been researched mainly regarding families and schools. However, there are children and adolescents who live outside of their families of origin in various forms of residential accommodation together with other young people and staff. It can be assumed that food practices and eating habits are central and challenging topics in everyday life in these institutions. Therefore, this paper aimed to provide an overview of the empirical research on food practices in residential care for children and adolescents. We identified 11 studies presented in 19 publications. These studies examined data from 479 children and adolescents, as well as 187 staff members, from 48 residential care units in 8 countries. Due to the interdisciplinary research field, the included studies showed great heterogeneity in the examination of food. In summary, the main foci have been the meaning of food practices in residential care, food practices and forced migration, biopolicy, and nutrition and health. A major topic is the social dimension of food, especially the symbolic meaning in terms of providing care and "making a family". Nutritional or health aspects have been mainly analyzed in terms of eating disorders or providing enough food. Future research on food practices in residential care homes should also pay attention to quantitative designs that include a broader understanding of food, including its social and emotional facets.

Fine structure of the anterior median eyes of the funnel-web spider Agelena labyrinthica (Araneae: Agelenidae).

Only few electron microscopic studies exist on the structure of the main eyes (anterior median eyes, AME) of web spiders. The present paper provides details on the anatomy of the AME in the funnel-web spider Agelena labyrinthica. The retina consists of two separate regions with differently arranged photoreceptor cells. Its central part has sensory cells with rhabdomeres on 2, 3, or 4 sides, whereas those of the ventral retina have only two rhabdomeres on opposite sides. In addition, the rhabdomeres of the ventral retina are arranged in a specific way: Whereas in the most ventral part they form long tangential rows, those towards the center are detached and are arranged radially. All sensory cells are wrapped by unpigmented pigment cell processes. In agelenid spiders the axons of the sensory cells exit from the middle of the cell body; their fine structure and course through the eye cup is described in detail. In the central part of the retina efferent nerve fibres were found forming synapses along the distal region of the receptor cells. A muscle is attached laterally to each eye cup that allows mainly rotational movements of the eyes. The optical performance (image resolution) of these main eyes with relatively few visual cells is discussed.
