" I'd rather play than look at statues ": The Experiences of Children with Art Works and Interactive Devices at an Art Exhibition

Young children have been largely neglected in research dedicated to the art museum experience. The art exhibition "Tête à tête" ("Face-to-Face"), designed for 5-12 year olds, became an opportunity to bring an exploratory contribution to three research issues: the relationship that the young child has with works of art and interactive devices, the role the adult plays in this relationship and the benefits derived from the visit. Building on observation and interviews, the article shows that children's attention is clearly drawn more towards interactive devices than art works, yet at the same time, the hypothesis that interactive devices are directly detrimental to children's reception of art works could not be confirmed. The results also emphasize the limited role that adults play in guiding the children towards the art. In the end, both adults and children appear to be satisfied overall with the playful and interactive dimension of their experience. Following this, art museums should questions themselves on how to specifically help families to better guide the young child's perspective towards the art works themselves, and also rely on the adult to encourage, in the child, a more active approach to the art work.Art exhibitions; child; family; museum experience; interactive devices; learning; interpretation; interpretation aids

Closing the Loop: Engaging in a Sustainable and Continuous Cycle of Authentic Assessment to Improve Library Instruction

This study demonstrates how a team of librarians sustained authentic assessment across multiple studies in order to inform changes to an information literacy curriculum. It demonstrates the cyclical and action-based nature of assessment, including closing one loop only to reopen another and begin the assessment process again, emphasizing the importance of sustainability and making changes that increase student learning. Researchers analyzed 79 English composition papers for evidence of information literacy skills, expanding upon a previous study which established information literacy skill benchmarks. Findings from the previous study led to the development of new library instruction lessons, which targeted skills students struggled with – mainly topic refinement and information synthesis. To measure the impact of the modifications, the authors used two rubrics as well as a citation analysis to identify shifts in student learning. Findings indicate that the new lessons contribute to student improvements in synthesis, topic refinement, and source variety. This study illustrates the importance of engaging in an ongoing cycle of assessment and continually making improvements to instruction practices while implementing evidence-based decisions

Need for Early Interventions in the Prevention of Pediatric Overweight: A Review and Upcoming Directions

Childhood obesity is currently one of the most prevailing and challenging public health issues among industrialized countries and of international priority. The global prevalence of obesity poses such a serious concern that the World Health Organization (WHO) has described it as a “global epidemic.” Recent literature suggests that the genesis of the problem occurs in the first years of life as feeding patterns, dietary habits, and parental feeding practices are established. Obesity prevention evidence points to specific dietary factors, such as the promotion of breastfeeding and appropriate introduction of nutritious complementary foods, but also calls for attention to parental feeding practices, awareness of appropriate responses to infant hunger and satiety cues, physical activity/inactivity behaviors, infant sleep duration, and family meals. Interventions that begin at birth, targeting multiple factors related to healthy growth, have not been adequately studied. Due to the overwhelming importance and global significance of excess weight within pediatric populations, this narrative review was undertaken to summarize factors associated with overweight and obesity among infants and toddlers, with focus on potentially modifiable risk factors beginning at birth, and to address the need for early intervention prevention

Rock Glacier Characteristics Under Semiarid Climate Conditions in the Western Nyainqêntanglha Range, Tibetan Plateau

Abstract Rock glaciers are receiving increased attention as a potential source of water and indicator of climate change in periglacial landscapes. They consist of an ice‐debris mixture, which creeps downslope. Although rock glaciers are a wide‐spread feature on the Tibetan Plateau, characteristics such as its ice fraction are unknown as a superficial debris layer inhibits remote assessments. We investigate one rock glacier in the semiarid western Nyainqêntanglha range (WNR) with a multi‐method approach, which combines geophysical, geological and geomorphological field investigations with remote sensing techniques. Long‐term kinematics of the rock glacier are detected by 4‐year InSAR time series analysis. The ice content and the active layer are examined by electrical resistivity tomography, ground penetrating radar, and environmental seismology. Short‐term activity (11‐days) is captured by a seismic network. Clast analysis shows a sorting of the rock glacier's debris. The rock glacier has three zones, which are defined by the following characteristics: (a) Two predominant lithology types are preserved separately in the superficial debris patterns, (b) heterogeneous kinematics and seismic activity, and (c) distinct ice fractions. Conceptually, the studied rock glacier is discussed as an endmember of the glacier—debris‐covered glacier—rock glacier continuum. This, in turn, can be linked to its location on the semiarid lee‐side of the mountain range against the Indian summer monsoon. Geologically preconditioned and glacially overprinted, the studied rock glacier is suggested to be a recurring example for similar rock glaciers in the WNR. This study highlights how geology, topography and climate influence rock glacier characteristics and development.Plain Language Summary Climate change has begun to impact all regions of our planet. In cold regions, such as high‐mountain areas, rising temperatures lead to massive melting of glaciers. Besides this evident loss of ice, permafrost, a long‐term ice resource hidden in the subsurface, has started to thaw. Rock glaciers as visible permafrost‐related landforms consist of an ice‐debris mixture, which makes them creep downslope. Due to this movement and their recognizable shape, rock glaciers are permafrost indicators in high‐mountain areas. We investigate one rock glacier in the western Nyaingêntanglha Range (Tibetan Plateau) using field and remote sensing methods to understand its development and to know the current state of its ice core. Our main outcome is, that the heterogeneous creeping behavior, the properties of the debris cover as well as the internal distribution of ice are the results of a continuous development from a glacier into today's rock glacier. In particular, the high ice content in particular sections points to such a glacial precondition. The debris layer covering the internal ice attenuates the effect of climate warming. This makes the rock glacier and similar rock glaciers found in the northern part of the mountain range important future water resources for the semiarid region.Key Points Geophysical and remote sensing methods in concert reveal the morphostructure, ice fraction, and kinematics of the studied rock glacier Rock glacier characteristics are controlled by geology, topography and climate on the Tibetan Plateau The studied rock glacier is conceptually interpreted as the endmember of a glacier—debris‐covered glacier—rock glacier continuu

Qualification sanitaire des troupeaux, représentations du risque selon les acteurs et les disciplines

La qualification sanitaire vise à établir de manière objective et fiable le statut sanitaire d'un animal ou d'un ensemble d'animaux au regard d'une maladie infectieuse. Concevoir une qualification sanitaire repose sur des connaissances biologiques concernant l'agent pathogène, ses voies de transmission et les moyens de détection de la maladie. Les modèles mathématiques et les outils statistiques et probabilistes permettent d'intégrer ces connaissances tout en prenant en compte l'incertitude et la variabilité des données biologiques. Les sciences humaines apportent un éclairage sur les enjeux, les perceptions et les logiques des individus et des collectifs, afin d'étudier la demande et l'acceptabilité de la qualification sanitaire. Chaque discipline apporte ainsi son point de vue sur la notion de risque sous-jacente à la démarche de qualification. Cette approche interdisciplinaire nécessite une coconstruction de la recherche, qui doit dépasser les différences culturelles et épistémologiques entre disciplines. Elle n'obéit pas à un seul type de rationalité, scientifique ou juridico-administrative ; elle mobilise nécessairement des connaissances savantes et des savoirs empiriques et dépend de nombreuses décisions pouvant engendrer convergences ou contradictions.
