The social institution of sport reflects a society that presupposes the values, mores, norms, and standards of the majority and subsequently determines who can participate in sport and who can be identified as an athlete. Recognizing the growing importance of disability sport to people with disabilities, the purpose of this study was to use the construct of symbolic interactionism to examine the identity development of adolescent girls with physical disabilities who participate in organized wheelchair sports with a specific focus on athletic identity development. An understanding of how the girls' interaction with various socializing agents through a wheelchair sport program to develop an athletic identity was developed through interviews. Results are presented utilizing Keliber's framework for identity development through leisure participation, including sport.
A comparative analysis of the composition of milk produced during the first 14 days of lactation by mothers who deliver prematurely and those who deliver at term is described and these values are contrasted with the composition of donor milk specimens. Twenty-four-hour milk collections (days 3, 7, and 14 postpartum) were obtained from nine mothers delivered between 37 to 42 wk gestation (term) and from 14 mothers who delivered between 28 to 36 wk gestation (preterm). A single spot milk collection was obtained from nine mothers who were 6 to 10 months postpartum (donor). Term and preterm milk was compared on specific postpartum days using an analysis of covariance controlling for 24-h milk volume. The protein, carbohydrate, fat, and energy content varied in a similar fashion in term and preterm milk over the 14 postpartum days studied. Furthermore, there was no significant difference between the two milk groups on any single postpartum day evaluated in terms of protein, carbohydrate, fat, or energy concentration. The milk volumes were significantly greater from the mothers delivered at term on days 7 and 14 (p less than 0.01) and the protein content of both term and preterm milk was negatively correlated with milk volume (r = -0.6 or more on each day studied). The nutrient and energy composition of spot donor milk was highly variable and frequently quite different from either term or preterm 24-h milk collections. These data indicate that milk from mothers who deliver prematurely does not contain significantly different concentrations of nutrients or energy than milk from mothers delivered at term and suggest that the differences previously noted between the two groups may be related to 24-h milk volume.
A comprehensive understanding of common diseases of backyard poultry flocks is important to providing poultry health information to flock owners, veterinarians, and animal health officials. We collected autopsy reports over a 3-y period (2015-2017) from diagnostic laboratories in 8 states in the United States; 2,509 reports were collected, involving autopsies of 2,687 birds. The primary cause of mortality was categorized as infectious, noninfectious, neoplasia or lymphoproliferative disease, or undetermined. Neoplasia or lymphoproliferative disease was the most common primary diagnosis and involved 42% of the total birds autopsied; 63% of these cases were diagnosed as Marek's disease or leukosis/sarcoma. Bacterial, parasitic, and viral organisms were commonly detected, involving 42%, 28%, and 7% of the birds autopsied, respectively, with 2 or more organisms detected in 69% of birds. Our findings demonstrate the importance of educating flock owners about disease prevention and biosecurity practices. The detection of zoonotic bacteria including paratyphoid salmonellae, Campylobacter spp., Listeria monocytogenes, and Mycobacterium avium, and the detection of lead and other heavy metals, indicate public health risks to flock owners and consumers of backyard flock egg and meat products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
