Attention, and Why it Matters
No full textIn this episode, where both of us find ourselves away from our usual recording studios, we first chat about Oliver\u27s missionary trip to Canada. Then we move to discuss the essential topic of attention, including the effect of attention economies, what attention is, how it connects to meaningful living, how, conversely, its fragmentation has numerous deleterious effects, how the Scriptures put a premium on the proper nurturing of attention, and how for Paul a life of contentment tracks our ability to direct our thoughts to subjects that matter most
Multimodal Analysis of Secondary Cerebellar Alterations after Pediatric Traumatic Brain Injury
No full textImportance: Traumatic brain injury (TBI) is known to cause widespread neural disruption in the cerebrum. However, less is known about the association of TBI with cerebellar structure and how such changes may alter executive functioning. Objective: To investigate alterations in subregional cerebellum volume and cerebral white matter microstructure after pediatric TBI and examine subsequent changes in executive function. Design, Setting, and Participants: This retrospective cohort study combined 12 data sets (collected between 2006 and 2020) from 9 sites in the Enhancing Neuroimaging Genetics Through Meta-Analysis Consortium Pediatric TBI working group in a mega-analysis of cerebellar structure. Participants with TBI or healthy controls (some with orthopedic injury) were recruited from trauma centers, clinics, and institutional trauma registries, some of which were followed longitudinally over a period of 0.7 to 1.9 years. Healthy controls were recruited from the surrounding community. Data analysis occurred from October to December 2022. Exposure: Accidental mild complicated-severe TBI (msTBI) for those in the TBI group. Some controls received a diagnosis of orthopedic injury. Main Outcomes and Measures: Volume of 18 cerebellar lobules and vermal regions were estimated from 3-dimensional T1-weighted magnetic resonance imaging (MRI) scans. White matter organization in 28 regions of interest was assessed with diffusion tensor MRI. Executive function was measured by parent-reported scores from the Behavior Rating Inventory of Executive Functioning. Results: A total of 598 children and adolescents (mean [SD] age, 14.05 [3.06] years; range, 5.45-19.70 years; 386 male participants [64.5%]; 212 female participants [35.5%]) were included in the study, with 314 participants in the msTBI group, and 284 participants in the non-TBI group (133 healthy individuals and 151 orthopedically injured individuals). Significantly smaller total cerebellum volume (d = -0.37; 95% CI, -0.52 to -0.22; P \u3c.001) and subregional cerebellum volumes (eg, corpus medullare; d = -0.43; 95% CI, -0.58 to -0.28; P \u3c.001) were observed in the msTBI group. These alterations were primarily seen in participants in the chronic phase (ie, \u3e6 months postinjury) of injury (total cerebellar volume, d = -0.55; 95% CI, -0.75 to -0.35; P \u3c.001). Smaller cerebellum volumes were associated with higher scores on the Behavior Rating Inventory of Executive Functioning Global Executive Composite score (β = -208.9 mm3; 95% CI, -319.0 to -98.0 mm3; P =.008) and Metacognition Index score (β = -202.5 mm3; 95% CI, -319.0 to -85.0 mm3; P =.02). In a subset of 185 participants with longitudinal data, younger msTBI participants exhibited cerebellum volume reductions (β = 0.0052 mm3; 95% CI, 0.0013 to 0.0090 mm3; P =.01), and older participants slower growth rates. Poorer white matter organization in the first months postinjury was associated with decreases in cerebellum volume over time (β=0.52 mm3; 95% CI, 0.19 to 0.84 mm3; P =.005). Conclusions and Relevance: In this cohort study of pediatric msTBI, our results demonstrated robust cerebellar volume alterations associated with pediatric TBI, localized to the posterior lobe. Furthermore, longitudinal cerebellum changes were associated with baseline diffusion tensor MRI metrics, suggesting secondary cerebellar atrophy. These results provide further understanding of secondary injury mechanisms and may point to new opportunities for intervention.
Following Jesus: Stories of Discipleship and Devotional Life
No full text“Dr. Scott Ward shares principles and experiences that will inspire you. The testimonies contained in this book will empower you as you consider your ministry calling and practices.” – Dr. Tracy Wood (Youth & Young Adult Ministries Director, North American Division of Seventh-day Adventists)
“Dr. Ward writes in an authentic and practical style that puts the reader at ease like we’ve just sat down in a conversation together. It is an easy read, packed full of practical examples that teachers and principals can immediately apply. But more deeply, the transparency found within the plethora of rich stories feels like rare and honest insights that remind us of how human we are. What I appreciate most are the psychosocial developmental stages for adolescents that Dr. Ward applies to discipleship. He brilliantly demonstrates the necessity for creating your ministry within a youth’s need for autonomy, belonging, and purpose.” – Angela White (Superintendent of School Growth, Oregon Conference of Seventh-day Adventists)
Scott R. Ward is a 30-year youth and young adult ministry veteran currently serving as Assistant Professor and Chair of the Department of Discipleship and Lifespan Education at the Seventh-day Adventist Theological Seminary at Andrews University. Dr. Ward is passionate about the discipleship opportunities that campus-based ministry provides— both at church schools and at public schools. Dr. Ward believes campus ministry is vital for teaching students how to apply their faith to real life.

Predator-Prey Dynamics of Bald Eagles and Glaucous-Winged Gulls
No full textIn this chapter we use a modification of the classic Lotka-Volterra predator-prey ordinary differential equation model to test whether rebounding bald eagle numbers were primarily responsible for declining numbers of gulls nesting on Protection Island, Washington
A Model of Cannibalism and Reproductive Synchrony
No full textMotivated by the empirical findings in Chaps. 7 – 9 that egg-laying synchrony is adaptive in the presence of egg cannibalism in gulls, we now extend the proof-of-concept cannibalism model in Chap. 11 to include the possibility of reproductive synchrony
Predicting Haul-Out Behavior by Harbor Seals
No full textIn this chapter we apply the differential equation-based modeling techniques developed in Chap. 1 to a marine mammal behavioral system. This research demonstrated that the same modeling techniques developed for bird behavior can be applied more broadly to other organisms. James Hayward, Shandelle Henson, and Brian Dennis, with undergraduate students Clara Logan, Catherine Parris, and Matthew Meyer, carried out this study which was initially reported in the Journal of Applied Ecology in 2005 [10]
