Mothers Leading By Example: Maternal Influence On Female Leadership In Kenya, Catherine Chege

Antioch University Dissertations & Theses

This qualitative research aimed to study the experiences of Kenyan female leaders and explore Kenyan maternal influence in their lived experiences. It examined how maternal influence shapes female leadership in Kenya by embodying relational and transformational leadership qualities and proves that maternal influence makes women congruent with leadership roles. Despite global advances recognizing the principle of women’s political, economic, and social equality, Kenyan women continue to be marginalized in many areas of society, especially in leadership and decision making. Kenyan women also continue to rank very low in their communities’ social hierarchy, yet they play a critical role in their …

Background: Hip-worn accelerometers are commonly used, but data processed using the 100 counts per minute cut point do not accurately measure sitting patterns. We developed and validated a model to accurately classify sitting and sitting patterns using hip-worn accelerometer data from a wide age range of older adults. Methods: Deep learning models were trained with 30-Hz triaxial hip-worn accelerometer data as inputs and activPAL sitting/nonsitting events as ground truth. Data from 981 adults aged 35–99 years from cohorts in two continents were used to train the model, which we call CHAP-Adult (Convolutional Neural Network Hip Accelerometer Posture-Adult). Validation …

the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study. Dietary intake was assessed using a 74-item validated Food Frequency Questionnaire. Perceived stress domains …

Development Of A Food Composition Database For Assessing Nitrate And Nitrite Intake From Animal-Based Foods, Liezhou Zhong, Alex H. Liu, Lauren C. Blekkenhorst, Nicola P. Bondonno, Marc Sim, Richard J. Woodman, Kevin D. Croft, Joshua R. Lewis, Jonathan M. Hodgson, Catherine P. Bondonno

Research outputs 2022 to 2026

Scope:

Nitrate and nitrite are approved food additives in some animal-based food products. However, nitrate and nitrite in foods are strictly regulated due to health concerns over methaemoglobinaemia and the potential formation of carcinogenic nitrosamines. In contrast, plants (like leafy vegetables) naturally accumulate nitrate ions; a growing body of research reveals beneficial metabolic effects of nitrate via its endogenous conversion to nitric oxide. To refine the association of dietary nitrate and nitrite intake with health outcomes, reliable measures of nitrate and nitrite intake from dietary food records are required. While a vegetable nitrate content database has been developed, there is …
