Adaptability, Engagement, and Degree Completion:A Longitudinal Investigation of University Students

© 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. University entry and the passage through university is a time of great change. The extent to which students are able to adjust to successfully navigate this change (adaptability) is likely to influence their academic outcomes. Prior research has identified a link between university students’ adaptability and academic achievement via behavioural engagement. The current longitudinal study extends this research by examining whether university students’ adaptability predicts degree completion via behavioural engagement. Undergraduate students (N = 186) were surveyed for their adaptability and behavioural engagement at degree commencement. Their completion status was extracted from the University Records System at the end of the degree. Findings showed that adaptability predicts both positive and negative behavioural engagement, and that negative (but not positive) behavioural engagement predicts degree completion. Adaptability was also found to influence degree completion indirectly via negative behavioural engagement. These findings hold important theoretical and practical implications for educators and researchers seeking to understand how students manage the transition to university and the extent to, and mechanisms by which students’ adaptability is associated with university degree completion

Exposure to depleted uranium does not alter the co-expression of HER-2/neu and p53 in breast cancer patients

<p>Abstract</p> <p>Background</p> <p>Amongst the extensive literature on immunohistochemical profile of breast cancer, very little is found on populations exposed to a potential risk factor such as depleted uranium. This study looked at the immunohistochemical expression of HER-2/neu (c-erbB2) and p53 in different histological types of breast cancer found in the middle Euphrates region of Iraq, where the population has been exposed to high levels of depleted uranium.</p> <p>Findings</p> <p>The present investigation was performed over a period starting from September 2008 to April 2009. Formalin-fixed, paraffin-embedded blocks from 70 patients with breast cancer (62 ductal and 8 lobular carcinoma) were included in this study. A group of 25 patients with fibroadenoma was included as a comparative group, and 20 samples of normal breast tissue sections were used as controls. Labeled streptavidin-biotin (LSAB+) complex method was employed for immunohistochemical detection of HER-2/neu and p53.</p> <p>The detection rate of HER-2/neu and p53 immunohistochemical expression were 47.14% and 35.71% respectively in malignant tumors; expression was negative in the comparative and control groups (p < 0.05).</p> <p>HER-2/neu immunostaining was significantly associated with histological type, tumor size, nodal involvement, and recurrence of breast carcinoma (<it>p </it>< 0.05), p53 immunostaining was significantly associated with tumor size, nodal involvement and recurrence of breast cancer (<it>p </it>< 0.05). There was greater immunoexpression of HER-2/neu in breast cancer in this population, compared with findings in other populations.</p> <p>Both biomarkers were positively correlated with each other. Furthermore, all the cases that co-expressed both HER-2/neu and p53 showed the most unfavorable biopathological profile.</p> <p>Conclusion</p> <p>P53 and HER-2/neu over-expression play an important role in pathogenesis of breast carcinoma. The findings indicate that in regions exposed to high levels of depleted uranium, although p53 and HER-2/neu overexpression are both high, correlation of their expression with age, grade, tumor size, recurrence and lymph node involvement is similar to studies that have been conducted on populations not exposed to depleted uranium. HER-2/neu expression in breast cancer was higher in this population, compared with results on non-exposed populations.</p

Development of a culturally anchored qualitative approach to conduct and analyze focus group narratives collected in diné (Navajo) communities to understand the impacts of the gold king mine spill of 2015

The Gold King Mine Spill (Spill) occurred in August 2015 upstream from Silverton, Colorado and released three million gallons of contaminated water into the Animas River, a tributary to the San Juan River that flows across the Navajo Nation. Using principles of community-engaged re-search, the Gold King Mine Spill Diné Exposure Project co-developed a culturally anchored approach to conduct focus groups and analyze narratives collected in three Diné (Navajo) communities along the San Juan River within 9 months of the Spill. Focus group questions were designed to document the socio-cultural impacts of the Spill. This paper: (1) outlines the partnerships and approvals; (2) describes focus group design, training, data collection and analysis; and (3) reflects on the use of a culturally anchored approach in Indigenous, specifically Diné-centered research. Diné social and cultural etiquette and concepts of relationality were used to adapt standard (non-Indigenous) qualitative methods. Findings describe community perceptions of short-term impacts of the disaster, as well as past and present injustices, communication related to the Spill, and concerns of persistent threats to Diné lifeways. The culturally anchored approach was critical in fostering trust with Diné participants and aligned with the candor of the discussions. © 2021 by the authors.
