Sleep Knowledge, Attitudes, and Behaviors of Professional Male Rugby League Athletes : Does Knowledge Translate Into Practice?
(2026-05-18) Sharples, Alice; Fullagar, Hugh H.K.; Hulin, Billy; Duffield, Rob; Department of Sport Science
OBJECTIVE: To describe sleep behaviors of male rugby league athletes and examine the association with self-reported sleep behaviors, attitudes, and knowledge. METHODS: Twenty-two rugby league athletes completed 7 consecutive nights of sleep monitoring using wrist-worn ActiGraphy, with the Sleep Practices and Attitudes Questionnaire completed at the commencement of the monitoring period. ActiGraphy measures included time in-bed (hh:mm), time out-of-bed (hh:mm), duration in bed (minutes), sleep duration (minutes), sleep efficiency (percentages), sleep onset latency (minutes), wake after sleep onset (minutes), and number of awakenings. The Sleep Practices and Attitudes Questionnaire assessed self-reported sleep behaviors, sleep hygiene practices, and sleep knowledge. Linear regressions determined associations between objective sleep measures and subjective self-reported sleep behaviors, sleep knowledge, and sleep attitudes. RESULTS: Sleep behaviors showed mean bedtime at 10:25 PM (45) minutes and wake time 6:30 AM (25) minutes, with 484 (41) minutes in bed. Sleep efficiency was 73% (5%), resulting in a sleep duration of 355 (42) minutes. In contrast, subjective data reported sleep duration as 7.5 (1.0) hours. A small association was observed between lower objective sleep efficiency and longer subjective sleep duration (P < .05, r2 = .21). Earlier bedtimes related to better coping with chronic insomnia (r2 = .23, P = .02) but showed small associations with greater in-bed activities (r2 = .25, P < .05). Longer time in bed and increased sleep duration had small associations with poorer coping with chronic insomnia strategies (r2 = .25 and r2 = .24, respectively; P < .05). No associations existed between sleep behaviors and sleep knowledge (P < .05). CONCLUSIONS: Suboptimal sleep duration (<8 h) and efficiency (<85%) exist in this cohort of players, despite high sleep knowledge. Therefore, sleep education needs to consider influencing factors on sleep behaviors when designing sleep education programs.

Beyond one-system thinking exploring design methods for understanding the digital work environment
(2026-08-11) Larusdottir, Marta; Cajander, Åsa; Department of Computer Science
Modern IT systems often fail to adequately support users’ everyday work, negatively affecting both performance and well-being. A key reason is that system development typically focuses on one system rather than considering how users interact with multiple systems at work. This paper argues that digitalisation efforts must move beyond traditional, system-bounded design to explicitly address the whole digital work environment. This synthesis study examines three design methods aimed at improving understanding of digital work environments: Contextual Personas and Contextual Think-Aloud, applied in student software projects, and the Vision Seminars method, used in a large-scale, realistic software project. All three methods seek to help IT professionals gain deeper insights into how users work across multiple systems. A qualitative meta-analysis study of six empirical studies is conducted, assessing the strengths, weaknesses, opportunities, and threats of each design method. The findings indicate that the design methods support a better understanding of users’ digital work environments, incorporating not only technical aspects but also well-being and psychological and social dimensions. Identified weaknesses involve risks of stereotyping, challenges for some users during evaluation, and high resource demands. Overall, the paper concludes that designing systems aligned with real digital work environments is both necessary and achievable.
The Cascading Effects of Policy Reforms: Curriculum, Knowledge and Equal Opportunities
(University of Iceland, School of Education, Faculty of Subject Teacher Education, 2026-10-08) Jónasdóttir, María; Elsa Eiríksdóttir og Guðrún Ragnarsdóttir; Faculty of Subject Teacher Education (UI); Deild faggreinakennslu (HÍ); School of Education (UI); Menntavísindasvið (HÍ)
This thesis examines how recent policy, governance and curriculum reforms have reshaped the conditions under which Icelandic upper secondary academic education operates, and how these changes influence students’ opportunities to access disciplinary knowledge that prepares them for higher education. Focusing on Iceland as a case, the study analyses the effects of decentralisation, competency-based curriculum policy, market-oriented governance and a reform that reduced the time of academic programs from four years to three, on curriculum structures and study pathways. Drawing on critical policy analysis and social realist curriculum theory, the thesis adopts a system-level perspective on curriculum organisation. Rather than examining the content of individual subjects or pedagogy, the analysis focuses on the structural and institutional conditions that shape epistemic access.
Using three empirical articles, the study investigates variations in programme structures, credit allocation, levels of advancement, and the availability and stability of progression pathways across school types and locations. The findings reveal substantial structural fragmentation in upper secondary academic education. As responsibility for curriculum-making has been redistributed to individual schools operating under uneven institutional conditions, access to cumulative disciplinary pathways has become increasingly dependent on local capacity, including enrolment size, staffing and funding incentives. These conditions particularly affect subjects organised around hierarchical knowledge structures, such as mathematics and natural sciences, where stable sequencing and progression are essential for cumulative learning, as well as foreign languages. Interpreted through a social realist lens, the findings indicate a weakening of key curriculum principles, including classification, sequencing, and progression. This weakening undermines students’ epistemic access by producing uneven opportunities for cumulative disciplinary learning. From a distributional justice perspective, the study demonstrates that inequality emerges not primarily from individual choice or ability, but from structurally patterned differences in curricular access.
The thesis contributes to research on curriculum, education policy and governance, and educational equity by showing how system-level arrangements shape the conditions for disciplinary knowledge. It argues that ensuring equitable preparation for higher education requires renewed attention to curriculum coherence, institutional capacity, and the role of the state in guaranteeing students’ entitlement to knowledge.
Synthesis, characterization and biological activity of the Cu (II)-1,3-PDTA [(Cu (II) (PDTA)] complex for the control of Erwinia chrysanthemi (soft rot) in the parsley manioc (Arracacia xanthorrhiza Bancroft)
(2025-01) de Almeida Teixeira, Cristiane Freitas; Carvalho, Claudio Teodoro; Zárate, Néstor Antonio Heredia; Fonseca, Gustavo Graciano; de Arruda, Eduardo Jose; Faculty of Natural Resource Sciences
Synthesis, characterization and biological activity of the Cu(II)-1,3-PDTA complex was performed by two synthetic routes: sodium and carbonate pathways. The Cu (II)-1,3-PDTA complex can be easily produced by the 1,3-PDTA binder, commercially available as Trilon F (BASF) which is available as sodium or acid salt for the coordination of Cu (II). The biological activity of the Cu (II)-1,3-PDTA [Cu (II)-PDTA] complex was performed to analyze the activity against the bacterium Erwinia chrysanthemi Bancroft. The bacterium is the causative agent of soft rot in the parsley maniac (Arracacia xanthorrhiza Bancroft). The bacterium was isolated from parsley manioc infected with soft rot. The metal complex sensitivity tests were performed by diffusion antibiogram. The mean values of the halos and standard deviations of the zones of inhibition were obtained for the [Cu (II) (PDTA)] and Streptomycin complexes. The concentrations of the complexes evaluated were 10-3, 10-2 and 10-1 M (equivalent to 36.3 g L-1 (3.63%), 3.63 g L-1 (0.363%) and 0.363 g L-1 (0.0363%), respectively). The halos were 25.0 ± 1.2 mm for control. For [Cu (II) (PDTA)] complexes, the obtained values were 9.5 ± 0.6, 15.0 ± 0.8 and 24.0 ± 0.8 via sodium and 12.0 ± 1.6, 25.0 ± 0.8 and 31.0 ± 1.9 via carbonate, for 10-3, 10-2 and 10-1 M, respectively. The results showed that the bactericidal activity of the Cu (II)-1,3-PDTA complex obtained by the two synthetic routes are adequate for the control of Erwinia chrysanthemi Bancroft.
