Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo Dec 2021

Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo

Tanzania Journal of Science

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin

Meaning-Making Dynamics Of Job Interview Performances, Jacquelyn K. Bertman Dec 2021

Meaning-Making Dynamics Of Job Interview Performances, Jacquelyn K. Bertman

Graduate Masters Theses

Behavioral interviewing has become a popular technique used across fields to assess the fitness of job seekers (Roulin & Bangerter, 2012; Powers, 2000). This particular style of interviewing calls on the interviewee to narrate their prior experiences in the workforce, with the idea that past behavior on the job is prelude to future job performance. The answers (stories) follow a specific format in order to be considered successful, one that adheres to the style and organization of the dominant Discourse (Gee, 1989). However, storytelling is a culturally situated practice and candidates from diverse backgrounds may construct their narratives outside of …


Long Term Predictive Modeling On Big Spatio-Temporal Data, Yong Zhuang Dec 2021

Long Term Predictive Modeling On Big Spatio-Temporal Data, Yong Zhuang

Graduate Doctoral Dissertations

In the era of massive data, one of the most promising research fields involves the analysis of large-scale Spatio-temporal databases to discover exciting and previously unknown but potentially useful patterns from data collected over time and space. A modeling process in this domain must take temporal and spatial correlations into account, but with the dimensionality of the time and space measurements increasing, the number of elements potentially contributing to a target sharply grows, making the target's long-term behavior highly complex, chaotic, highly dynamic, and hard to predict. Therefore, two different considerations are taken into account in this work: one is …

Spanish Guitarists In Nineteenth-Century São Paulo, Flavia Prando

Soundboard Scholar

This article explores the presence and activities of guitarists in nineteenth-century São Paulo. Drawing on reviews written by the pianist Alexandre Levy in 1890, I analyze concerts by Martínez Toboso and Gil-Orozco, two Spanish guitarists whose duo seems to have been the first to perform formal concerts in São Paulo. I also investigate Gil-Orozco’s subsequent work in São Paulo, where he lived for seventeen years (1890–1907), playing an essential role in the guitar’s development in the city.
