Strategies to Promote Oral Motor Skills and Progression of Foods for Infants and Young Children with Feeding Concerns

Eating is a primary occupation for individuals from birth through adulthood. However, some infants and young children experience difficulty and frustration as they begin to eat and transition to foods with texture. Field, Garland, and Williams (2003) determined that up to 80% of children with developmental disabilities experienced problems with feeding. There is a need for providing education and support for the families of these children (White-Traut & Norr, 2009). Pilkington (2006) conveyed that supporting and building the parent\u27s capacity for caring for their child resulted in enhanced outcomes for the infant or child. Current resources may not be parent-friendly or may not provide appropriate, detailed strategies that apply to a child with feeding difficulties. In order to address this issue, the goal of this scholarly project was to create a manual that occupational therapists could use to educate and support parents and caregivers. The primary methodology used to create this product included an extensive review of the literature, including research articles, textbooks, and resources currently available to families and caregivers. The Ecological Model of Occupation primarily guided the development of the resource manual based on the relationship between person, context, and the task, and the impact that these variables have on performance. This resource manual contains research-based educational materials that offer useful strategies that occupational therapists can use when providing interventions to promote advancement of feeding skills and assist with the progression of foods for infants and toddlers with feeding difficulties. Areas of focus include the role of the occupational therapist and the role of the parent in teaching their child to eat. Typical feeding skill development is outlined to assist parents in understanding sequential steps to feeding development. Environmental factors and positioning strategies are addressed for infants and toddlers. A variety of treatment interventions and recommendations to assist in improving feeding for infants and young children are also provided

How Do Tor Users Interact With Onion Services?

Onion services are anonymous network services that are exposed over the Tor network. In contrast to conventional Internet services, onion services are private, generally not indexed by search engines, and use self-certifying domain names that are long and difficult for humans to read. In this paper, we study how people perceive, understand, and use onion services based on data from 17 semi-structured interviews and an online survey of 517 users. We find that users have an incomplete mental model of onion services, use these services for anonymity and have varying trust in onion services in general. Users also have difficulty discovering and tracking onion sites and authenticating them. Finally, users want technical improvements to onion services and better information on how to use them. Our findings suggest various improvements for the security and usability of Tor onion services, including ways to automatically detect phishing of onion services, more clear security indicators, and ways to manage onion domain names that are difficult to remember.Comment: Appeared in USENIX Security Symposium 201

Chapter Welfare and demography in the time of Malthus. Regional and local variations in poor relief and population developments in Flanders, c. 1750-1810

Flanders represents a particularly interesting region for research that aims to investigate the development of socio-economic inequalities at the local and regional level. The relationship between and effects of structural socio-economic characteristics on the one hand and micro-level variations on the other hand remain unclear. The data collected by the STREAM project (streamproject.ugent.be) together with its tailored geographical information system (GIS) allow us to explore these relationships for the rural parishes of early modern Flanders. In this chapter we examine spatial patterns in poor relief and demographic behaviour and how these were interrelated

Language maintenance in friendships: second-generation German, Greek, and Vietnamese migrants

Our contribution explores the language maintenance (LM) patterns of children of migrants (second-generation) to Australia from three ethnolinguistic groups — German, Greek, and Vietnamese — in their same-age peer friendships. Focusing on the affective social relationship of “friendship” imagined as a dynamic fluid site of independence and a locale for identity formation, we scrutinize it as a pressure point for LM. The macro survey trends indicate that languages other than English (LOTE) are used in the friendship domain but with differing participations. Follow-up in-depth interviews reveal subtleties and complexities for LM practices. Co-presence of bilingual others in friendships proves to be a minimum but not sufficient condition for LM, particularly for German men and Greek women. Hyphenated belongings — for example, Vietnamese-, Greek-, German-Australians — construct varying LM alignments that reflect shared histories and authenticities (the migration experience) and the localizing of settlement (Australia)

Differences in collagen prolyl 4-hydroxylase assembly between two Caenorhabditis nematode species despite high amino acid sequence identity of the enzyme subunits

The collagen prolyl 4-hydroxylases (P4Hs) are essential for proper extracellular matrix formation in multicellular organisms. The vertebrate enzymes are α2β2 tetramers, in which the β subunits are identical to protein disulfide isomerase (PDI). Unique P4H forms have been shown to assemble from the <i>Caenorhabditis</i> <i>elegans</i> catalytic α subunit isoforms PHY-1 and PHY-2 and the β subunit PDI-2. A mixed PHY-1/PHY-2/(PDI-2)<sub>2</sub> tetramer is the major form, while PHY-1/PDI- 2 and PHY-2/PDI-2 dimers are also assembled but less efficiently. Cloning and characterization of the orthologous subunits from the closely related nematode <i>Caenorhabditis</i> <i>briggsae</i> revealed distinct differences in the assembly of active P4H forms in spite of the extremely high amino acid sequence identity (92-97%) between the <i>C. briggsae</i> and <i>C. elegans</i> subunits. In addition to a PHY-1/PHY-2(PDI-2)<sub>2</sub> tetramer and a PHY-1/PDI-2 dimer, an active (PHY- 2)<sub>2</sub>(PDI-2)<sub>2</sub> tetramer was formed in <i>C. briggsae</i> instead of a PHY-2/PDI-2 dimer. Site-directed mutagenesis studies and generation of inter-species hybrid polypeptides showed that the N-terminal halves of the <i>Caenorhabditis</i> PHY-2 polypeptides determine their assembly properties. Genetic disruption of <i>C. briggsae phy-1</i> (<i>Cb-dpy-18</i>) via a <i>Mos1</i> insertion resulted a small (short) phenotype that is less severe than the dumpy (short and fat) phenotype of the corresponding <i>C. elegans</i> mutants (<i>Ce-dpy-18</i>). <i>C. briggsae</i> <i>phy-2</i> RNA interference produced no visible phenotype in the wild type nematodes but produced a severe dumpy phenotype and larval arrest in <i>phy-1</i> mutants. Genetic complementation of the <i>C. briggsae</i> and <i>C. elegans</i> <i>phy-1</i> mutants was achieved by injection of a wild type <i>phy-1</i> gene from either species

Flexible batch electrodialysis for low-cost solar-powered brackish water desalination

Globally, 1.6 billion people in rural regions face water scarcity. Expanding freshwater access via brackish groundwater desalination can provide additional resources to address this challenge. In this study, we have developed a time-variant electrodialysis reversal (EDR) technology that flexibly uses available solar energy for desalination. Our proposed photovoltaic-powered desalination system can vary pumping and EDR power to match the availability of intermittent solar power, maximizing the desalination rate. Our results show improved system performance with the direct use of 77% of available solar energy—91% more than in conventional systems—and a 92% reduction in battery reliance. In a village-scale desalination case study in India, these system improvements lead to a 22% reduction in water cost, making the technology competitive with the currently used on-grid, village-scale reverse osmosis systems that are mainly powered by fossil fuels. Future advances could further reduce costs, providing an improved, sustainable solution to water scarcity in remote areas
