Chitra Banerjee Divakaruni: A Bibliographic Review of Resources for Teachers
As a poet, short story writer, novelist and essayist, Divakaruni has gained a wide national and international audience. Her writing in multiple genres addresses cross-cultural complexities of self-identity, family relationships and community values. Most notable has been her continuing concern with these issues in connection with the experiences of Indian and Indian American women. Reviews of her work emphasize her boldly imaginative style of story-telling, poetic sensibility, creativity in genre crossing, and commitment to breaking down boundaries between serious and popular literature
Identifying and improving the fibre-degrading activity of rumen microbe-derived fibrolytic bacteria : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, Manawatū, New Zealand
The dairy industry is extremely important to the New Zealand (NZ) economy, and it accounts for approximately $16.6 billion in exports each year. In NZ, traditional feedstock for cattle, such as grass and hay, consists of cellulose-based fibrous material that have limited nutritional value due to their inherent resistance to degradation. As commercially available feed treatments that use fibrolytic enzymes (FEs) from aerobic fungi are not currently available in NZ, it is possible that pre-treatment of such foodstuffs with rumen microbe-derived FEs could enhance fibre degradation, boosting animal performance and productivity as such enzymes should be better suited to the anaerobic conditions of the rumen.
The main aim of this thesis was to identify effective fibre-degrading rumen bacteria and
attempt to improve their fibre-degrading, or fibrolytic, activity using non-genetically modified methods. This was carried out by culturing 15 different rumen bacterial isolates on five separate fibrous substrates, which resulted in 46 strain/substrate combinations that were screened for fibrolytic activity.
The fibrolytic activity of each strain/substrate combination was assessed using two distinct
biochemical assays: 1) degradation of oat spelt xylan (OSX) or filter paper (FP), and 2) degradation of para-nitrophenol-conjugated substrates that represent major biochemical
linkages in the plant cell wall. Three candidate strains were chosen based on these results to
improve fibrolytic activity further using mutagenesis and positive selection, and of these, two strains showed a statistically significant increase in fibrolytic activity after 31 subcultures on ryegrass (RG). The secretomes of these two strains was then investigated using proteomic
methods, which included 1D SDS PAGE, in-gel trypsin digest and mass spectrometry.
The overall results from this research serve as a foundation for the development of a feed treatment to be used in NZ, which could provide financial benefit not only to dairy farmers, but the NZ economy as well
The Consequences of Structural Racism, Concentrated Poverty, and Violence on Young Men and Boys of Color
Defining violence broadly as "systemic injury directed against a group or geographic area," this research brief describes the scope of violence that black young men and boys face as a result of structural conditions. It recommends policy for addressing both the root causes of violence and the trauma that people are facing right now
