Preterm birth (gestational age < 37 weeks) is associated with delays in the development of executive functions and their precursors, including controlling attention and retaining task-relevant information. In the current study, we aim to examine the potential therapeutic effects of a novel cognitive tablet game, Dino Island (DI), and its implementation through a parent-delivered intervention program on cognitive development in preterm children.
Participants and Methods:
In total, 34 participants (M = 4.99 years old) were recruited from a perinatal follow-up clinic or through the community in Calgary, AB. Participants were randomly assigned to either the DI intervention (n = 20) or tablet-based educational control games (C; n = 14). Parents completed a 2-hour training program that included information about how to support their child through the intervention using behavioural supports and metacognitive strategies. Neuropsychological assessment was done prior to beginning the intervention and after 12 weeks of intervention. Various tests were used to assess near transfer measures of sustained attention, shifting attention, executive function, verbal working memory and inhibition, and to assess far transfer measures of language skills and early numeracy. Families tracked weekly progress using journals, with the goal of 3-4 30-minute sessions per week. Multiple ANCOVA analyses were run to analyze quantitative data using the pre-test score as a covariate.
Results:
A total of 21 participants completed the 12 weeks of intervention (DI: n = 11 and C: n = 10). Those who did not complete the intervention withdrew from the study or were unable to make a follow-up assessment due to COVID-19 restrictions. Groups did not significantly differ in age (DI: M = 4.92, C: M = 4.61), sex (DI: Female = 6, C: Female = 6), or in weeks preterm (DI: M = 29.49 weeks, C: M = 32.7 weeks).
Multiple ANCOVAs were run to determine the effect of either the DI or Control intervention on the cognitive measures after controlling for the pre-intervention score of participants. As compared to the Control group, the DI intervention group showed near transfer gains in sustained attention (F(1,7) = 5.1, p = 0.043), and executive functions (F(2,18) = 5.41, p = 0.014), as well as far transfer gains in phonetic awareness (F(2,16) = 11.63, p = 0.001), vocabulary and oral language skills (F(2,7) = 5.54, p = 0.014), and number identification fluency (F(2,17) = 11.37, p = 0.001). Detailed analyses will be discussed in the poster.
Conclusions:
This study provides preliminary support for the potential efficacy of the DI intervention when delivered by parents to children born preterm. Pre-post testing after 12 weeks of intervention indicated both near and far transfer gains. These results highlight the benefits of utilizing a tablet game format to facilitate collaborative parent-child interactions in cognitive intervention. This intervention provides a potential affordable and engaging alternative to existing cognitive interventions. Further investigation with a larger and more diverse sample is required.
This review considers current evidence on physical activity and dietary behaviours in the context of prostate cancer prevention and survivorship outcomes. Prostate cancer is the second most common cancer amongst men, with over 1⋅4 million newly diagnosed cases globally each year. Due to earlier detection via screening and advances in treatments, survival rates are amongst the highest of all cancer populations. However, hormone treatments (i.e. androgen deprivation therapy) can lead to undesirable body composition changes, increased fatigue and reduced health-related quality of life, which can impair the overall wellbeing of men living with and beyond prostate cancer. Existing research has only provided limited evidence that physical activity and nutrition can impact a man's risk of prostate cancer but cohort studies suggest they can influence survival outcomes after diagnosis. Additionally, data from observational and intervention studies suggest that habitual physical activity (or structured exercise) and healthy diets can help to ameliorate hormone-related treatment side-effects. Current physical activity guidelines state that prostate cancer patients should complete at least three sessions of moderate-intensity aerobic exercise per week, along with two resistance exercise sessions, but dietary guidelines for prostate cancer patients are less well defined. In conclusion, regular physical activity and nutritional interventions may improve survival outcomes and attenuate some adverse side-effects of hormone treatments in men with prostate cancer. However, further research is required to improve our understanding of the health impacts of physical activity (including structured exercise) and nutrition in relation to prostate cancer prevention and survivorship.
On January 13, 2018, a false ballistic missile alert that lasted 38 minutes was issued across Oahu, Hawaii, United States. As a result of a system failure, an erroneous text message was sent that stated, “Ballistic missile threat inbound to Hawaii. Seek immediate shelter.”
Aim:
The research team wanted to know the degree of reported anxiety triggered by the event and if knowledge, attitudes, or behaviors for individual/family emergency preparedness (EP) changed post-event.
Methods:
A 50-question survey that asked about individual and family EP pre- and post-event, and the level of anxiety triggered by the event, was administered to a convenience sample of full-time adult residents of Oahu. The study was conducted over a 6-8 week period post-event. Statistical analysis was used to identify factors associated with an increasing level of EP post-event and reported event-triggered anxiety.
Results:
209 participants completed the survey (29% male, 71% female) with about one half living with children. One third were essential workers. Key factors that correlate with increasing various areas of EP post-event include higher educational, receipt of electronic emergency alerts, prior emergency training, and higher reported connectedness to community. Those with higher event anxiety were more likely to develop and practice an EP plan post-event, encourage EP with friends, and report a higher level of community connectedness. The elderly were more likely to have higher levels of EP before and after the event but were less likely to receive emergency alert notifications or have EP training.
Discussion:
While the event was very unfortunate, it did seem to stimulate citizen disaster EP among some groups. Additional research should explore the utility of increasing EP education for communities immediately after disasters, tailoring this education for groups, and targeting the elderly for participation in the emergency alert system.
A fine-grained, up to 3-m-thick tephra bed in southwestern Saskatchewan, herein named Duncairn tephra (Dt), is derived from an early Pleistocene eruption in the Jemez Mountains volcanic field of New Mexico, requiring a trajectory of northward tephra dispersal of ~1500 km. An unusually low CaO content in its glass shards denies a source in the closer Yellowstone and Heise volcanic fields, whereas a Pleistocene tephra bed (LSMt) in the La Sal Mountains of Utah has a very similar glass chemistry to that of the Dt, supporting a more southerly source. Comprehensive characterization of these two distal tephra beds along with samples collected near the Valles caldera in New Mexico, including grain size, mineral assemblage, major- and trace-element composition of glass and minerals, paleomagnetism, and fission-track dating, justify this correlation. Two glass populations each exist in the Dt and LSMt. The proximal correlative of Dt1 is the plinian Tsankawi Pumice and co-ignimbritic ash of the first ignimbrite (Qbt1g) of the 1.24 Ma Tshirege Member of the Bandelier Tuff. The correlative of Dt2 and LSMt is the co-ignimbritic ash of Qbt2. Mixing of Dt1 and Dt2 probably occurred during northward transport in a jet stream.
Enacting high expectations for all students in the classroom is a complex undertaking. Underlying, out-of-awareness assumptions may lead to actions, behaviours or pedagogic choices that do not support these high expectations beliefs and intentions. For Indigenous education, this is compounded by public and professional discourses around deficit positioning, and by historical conditioning, where many Indigenous students do not see achieving in school as part of their cultural identity. High expectations are usually considered as a performance agenda — in terms of effort, learning and achievement. In this paper, we introduce the concept of high-expectations relationships where viewing and enacting high expectations through a relational lens equips educators with strategies to support such performance outcomes. We describe this relational lens where fair, socially just relating establishes a relational space of trust, thus enabling both student motivation and the firm, critically reflective relating necessary for quality learning. Using the voices of educators, we describe how high-expectations relationships can promote collegiate staff environments, strong teacher–student relationships and trusting and supportive relationships with parents and carers. We show how these positive educational attributes of any school community, seeded through a focus on high-expectations relationships, work to support the performance outcomes of a high-expectations educational agenda.
In this paper we describe methods for finding very small maximal subgroups of very large groups, with particular application to the subgroup 47:23 of the Baby Monster. This example is completely intractable by standard or naïve methods. The example of finding 31:15 inside the Thompson group $\text{Th}$ is also discussed as a test case.
The theory of representations of finite simple groups of Lie type in defining characteristic is somewhat advanced. The representations arise from those of the associated algebraic groups, and so some familiarity with the theory of algebraic groups is necessary in order to understand it. For an introduction to this theory see, for example, the survey article by Humphreys [51]. The enthusiastic reader may wish to consult Jantzen [58] for a more detailed exposition. Humphrey's classic book [50] provide a general exposition of the theory of algebraic groups and their representations, whilst Malle and Testerman's book [91] gives an excellent introduction to the general theory, subgroup structure, and representation theory of the finite and algebraic groups of Lie type, including a fuller discussion of all of the introductory material in this chapter.
In many respects, the study of the J2-candidates is easier than that of the J1-candidates, simply because there are far fewer of them: we just need to know about the representations in dimensions up to 12, and to be able to determine some of their properties, such as forms preserved and their behaviour under the actions of group and field automorphisms. Fortunately it is possible to extract this information starting from a superficial familiarity with the main results of the theory, principally the Steinberg Tensor Product Theorems. These theorems, together with the tables in [84], suffice to determine the representations.
