Comparison of serum immunoglobulin G half-life in dairy calves fed colostrum, colostrum replacer or administered with intravenous bovine plasma.
In calves, passive immunity of immunoglobulins can be acquired through ingestion of colostrum or colostrum replacers. Plasma can been used to supplement immunoglobulins in healthy or sick calves. Serum half-life of colostral derived immuglobulin G (IgG) is estimated to be 20 days. Half-life of IgG is important in determining response to antigens and timing of vaccination in calves. To date studies evaluating half-life of colostrum replacer or plasma derived IgG are lacking. The objectives of this study were to compare the serum half-life of IgG derived from colostrum, colostrum replacer and plasma in dairy calves reared up to 35 days of age. Thirty Jersey calves were randomly assigned to receive colostrum or colostrum replacer by oroesophageal tubing or plasma by intravenous administration. Serum samples were collected at 2, 5, 7, 10, 14, 21, 28 and 35 days. Serum IgG concentrations were determined by radial immunodiffusion. The results indicated that half-life for IgG in colostrum fed (28.5 days) or plasma transfused calves (27.3 days) was longer than colostrum replacer fed calves (19.1 days). Further studies are required to evaluate pathogen specific immunoglobulins in order to recommend vaccination timing in calves fed colostrum replacers
Survey study of the relationship between parents\u27 and teachers\u27 perceptions of what constitutes effective school -to -home communications
Even though guidelines at a suburban elementary school in Georgia were in place for teachers regarding frequency and methods of parent communication, it was unclear if these methods were being used consistently and effectively. Research has shown that effective communication increases student achievement, but there is a lack of research examining communication preferences of teachers and parents. Therefore, this study evaluated current practices by comparing parents\u27 and teachers\u27 perceptions of what constitutes effective school-to-home communications. The researcher administered questionnaires to a random sample of teachers and parents of 3rd, 4th, and 5th grade students to compare their perceptions of the communication methods currently used between school and home, and to expose any need for modification to current practices. Data analysis using a t-test for independent measures was used to compare the teachers\u27 and parents\u27 mean scores computed from the Likert-scaled survey. Based on the results of the independent samples t-test, there was a significant difference between teachers and parents in communication scores for all parts of the survey instruments. Specifically, teachers rated themselves higher than the parents rated the teachers\u27 practices. The results of this current study will be shared with the school\u27s leadership team to determine the need for modifications to the current practices in order to communicate more effectively. A future qualitative study could examine the particular preferences of parents regarding communication. This study highlights the need to educate teachers about adapting their communication practices to meet parents\u27 needs. The overall implications for social change include using this information to strengthen the partnership between school and home to increase overall student academic performance

Translingual literature: The bone people and Borderlands
This thesis proposes that by producing and existing within a translingual text, the ethnofeminist has found a way to subvert others\u27 construction of her and redefine her identity. In particular, the ethnofeminist uses code switching to select and reinvent meaning from the language system of the dominant culture while maintaining the language system of the marginal group. In combining two (or more) language systems within a literature she has created her own language
Supporting Children\u27s Language and Literacy Through Collaborative Shared Book Reading
Language and literacy skills are critical for academic success. Shared book reading is an evidence-based practice for improving a range of language and literacy skills in young children, including those with or at risk for learning disabilities. The aim of this paper is to describe how teachers and speech-language pathologists (SLPs) can collaborate to support young childrenās learning through shared book reading. An overview of shared book reading is presented, followed by a description of the collaboration, implementation of the shared book reading sessions, as well as instruction that can take place after the reading. By collaborating through shared book reading, teachers and SLPs can enhance their overall instructional quality to more effectively support the language and literacy needs of children with or at risk for learning disabilities
Motion Capture: Drawing and the Moving Image. Curated by Ed KrÄma and Matt Packer, Lewis Glucksman Gallery, Cork, 26 July-4 November 2012
The desire to record bodies in motion, regardless of technological capabilities, has been inherent in the visual arts for as long as they have been in existence. This is manifest in Werner Herzogās Cave of Forgotten Dreams (2010), in which the director is granted rare access to the Chauvet caves in southern France. The caves contain rock drawings, mainly of animals, that are thought to be 32,000 years old. Contemplating drawings of horses running, in which the movement is captured by several images overlaid on each other, so as to suggest motion, Herzog remarks that they resemble āproto-cinemaā
Dark fragments: contrasting corporealities in Pasolini's La ricotta
The short film La ricotta (Pier Paolo Pasolini, 1963) tells the story of Stracci, an extra working on a film of the life of Christ, which is presented in part via tableaux vivants of Mannerist paintings. Pasoliniās film is replete with formal, stylistic and narrative binaries. In this article, I examine a particularly emphatic binary in the film in the form of the abstract, ethereal corporeality of the Mannerist paintings versus the raw and bawdy corporeality of Stracci. I show that through the reenactment of the paintings and their literal embodiment, Pasolini creates a rapprochement and, ultimately, a reversal between the divine forms created by the Mannerists and Stracciās unremitting immanence, which, I argue, is allied to the carnivalesque and the cinematic body of Charlie Chaplinās Little Tramp. I examine how Pasolini gradually deposes the Mannerists, and thus the art-historical excesses and erotic compulsion he feels towards the crucifixion, substituting in their place the corporeal form of Stracci in all its baseness and profanity
