Item type:Item, Rapport sommaire : Apprentissage expérientiel et résultats des diplômés universitaires du Nouveau-Brunswick(DataNB, 2026-02-27) Afolabi, Sophia; McDonald, Ted; Miah, PabloL'apprentissage par l'expérience (EL) est devenu un domaine d'intérêt majeur au Nouveau-Brunswick, alors que la province multiplie les initiatives visant à renforcer l'engagement des étudiants et à soutenir le développement de la main-d'œuvre. Dans ce contexte, une étude menée par DataNB analyse la participation à l'EL chez les étudiants de premier cycle inscrits dans les quatre universités publiques du Nouveau-Brunswick entre 2015 et 2022. À l’aide de données administratives couplées provenant des programmes d’EL, des dossiers étudiants des établissements et du registre de l’assurance-maladie, l’étude compare les taux de participation à l’EL entre les groupes démographiques et académiques et examine la rétention des diplômés dans la province un et trois ans après la fin du programme. Les résultats montrent des variations importantes dans la participation à l’EL selon les établissements et les domaines d’études, en partie dues aux différences dans les pratiques de collecte de données et les exigences des programmes. La participation aux programmes EL est corrélée à une plus forte rétention des diplômés, en particulier chez les étudiants provenant de l’extérieur du Nouveau-Brunswick, bien que l’ampleur de ces différences soit modeste et largement influencée par la composition de la population étudiante. Les résultats de la régression indiquent que les participants aux programmes EL ont moins de chances de quitter la province après l’obtention de leur diplôme, tandis que l’intensité de la participation aux programmes EL ne présente qu’une association limitée avec la rétention. L’étude souligne l’intérêt des données couplées pour comprendre les parcours des étudiants et note que les résultats reflètent des corrélations plutôt que des effets de causalité.Item type:Item, Apprentissage expérientiel et résultats des diplômés universitaires du Nouveau-Brunswick(DataNB, 2026-02-27) Afolabi, Sophia; McDonald, Ted; Miah, PabloL'apprentissage par l'expérience (EL) est devenu un domaine d'intérêt majeur au Nouveau-Brunswick, alors que la province multiplie les initiatives visant à renforcer l'engagement des étudiants et à soutenir le développement de la main-d'œuvre.

Within this context, research by DataNB analyzes EL participation among undergraduate students enrolled in New Brunswick’s four public universities between 2015 and 2022. Using linked administrative data from EL programs, institutional student records, and Medicare registry data, the study compares EL participation rates across demographic and academic groups and examines graduate retention in the province one and three years after program completion. Findings show substantial variation in EL participation across institutions and fields of study, shaped in part by differences in data collection practices and program requirements. EL participation is correlated with higher graduate retention, particularly among students from outside New Brunswick, although the magnitude of these differences is modest and largely influenced by student composition. Regression results indicate that EL participants have lower odds of leaving the province after graduation, while EL intensity shows limited association with retention. The study highlights the value of linked data for understanding student pathways and notes that results reflect correlations rather than causal effects.Item type:Item, Linking declining Atlantic salmon (Salmo salar) populations with multidecadal changes in their marine foraging ecology(University of New Brunswick, 2026-02) Weigum, Emily; Samways, Kurt; Hayden, BrianAtlantic salmon (Salmo salar) populations have declined considerably, largely attributed to low marine survival linked to large-scale changes in oceanographic conditions. Yet the link between marine environmental change and Atlantic salmon growth, diet, and distribution remains poorly understood. Using stable isotope analysis of archived scales, this thesis examines spatial and temporal trends in salmon marine resource use and trophic ecology over the last 50 years. Carbon and nitrogen isotope ratios of salmon scale collagen revealed significant shifts in marine resource use by salmon foraging off West Greenland, coinciding with major ecosystem regime changes in the Northwest Atlantic. Amino acid δ15N-based trophic position estimates remained relatively stable through time, though high within-year variability suggests diverse foraging strategies among individuals. These results indicate that, although salmon trophic ecology has not undergone major secular shifts through time, salmon are likely influenced by bottom-up controls and prey availability. Comparisons of δ13C and δ15N from returning adults showed that one-sea-winter (1SW) and multi-sea-winter (MSW) salmon from the Outer Bay of Fundy and Southern Upland populations occupy distinct summer foraging areas, whereas both life histories from the Inner Bay of Fundy share a common but separate area. Isotopic enrichment of returning salmon and individuals caught in the Northwest Atlantic further supports population-specific differences in foraging. Correlations between δ¹³C and sea surface temperature offer promising insight into foraging locations, though their utility remains limited in coastal environments. Growth rate estimates from scale measurements revealed a long-term decline in marine growth, most evident in the first marine summer and varying across regions and life histories. In addition to temporal trends, spatial and individual-level variation highlighted trade-offs between freshwater size and early marine performance, including evidence of compensatory growth. Divergent growth trajectories between 1SW and MSW salmon point to distinct resource allocation strategies and potential genetic influences. Overall, this work highlights the value of long-term biological archives and stable isotope approaches for assessing migratory species’ responses to shifting marine ecosystems. The findings demonstrate that Atlantic salmon do not respond uniformly to environmental change, underscoring the importance of conservation and management strategies tailored to specific populations, life histories, and regions.Item type:Item, Cellulosic material derived hydrogels for self-powered sensing applications(University of New Brunswick, 2026-02) Wang, Baobin; Ni, YonghaoTENG derived self-powered sensor research has gained popularity due to the low cost, great availability, and easy fabrication in the new era of AIoT. Hydrogels with tunable structure and versatile properties can fulfill the requirement of self-powered sensors. Cellulosic materials have attracted much attention to the fabrication of multifunctional hydrogels due to unique physiochemical properties. In this thesis, a series of nanocellulose composite hydrogels via various network engineering were developed and their potential applications as self-powered sensors were investigated. A universal materials platform by synergistically integrating nanocellulose (in forms of CNCC, CNF, and CNC) was incorporated with structure engineering into various polymer networks (PAM, PVA, PAA). Specifically, electrostatic interactions between cationic nanocellulose and anionic g-C3N4, MXene and CNF, and multiple hydrogen bonds from tannic acid-functionalized nanoparticles were introduced. These strategies successfully overcome the classic trade-off between mechanical robustness and functionality, yielding materials with exceptional stretchability, high toughness, adhesiveness, and autonomous self-healing capabilities. The tailored compositions further endowed the hydrogels with high ionic conductivity, anti-freezing properties, and additional functionalities like UV-blocking and potent antibacterial activity. These attributes made them ideal for constructing high-performance strain sensors with high sensitivity and high durability, capable of detecting motions from large-scale joint movements to subtle physiological signals like pulse and exhalation. Furthermore, the hydrogels served as excellent electrode materials in single-electrode mode triboelectric nanogenerators (TENGs). The resulting self-powered devices efficiently converted biomechanical energy into electricity, achieving outputs up to 89.2 V, 1.8 µA, and a power density of 69.97 mW·m-2. A proof-of-concept demonstration validated their application as a self-powered communication interface for aphasia patients using Morse code, highlighting their potential in assistive healthcare and human-computer interaction. The preparation strategies and insights presented herein pave the way for next-generation wearable technologies that are more intelligent, adaptive, and seamlessly integrated with the human body.
