Opportunities & Possibilities: Posttraumatic Growth in Research & Practice milfamln
In this presentation, Richard Tedeschi, Ph.D. will discuss the theoretical model and research basis of posttraumatic growth, the process by which trauma survivors often find valuable changes in how they live life in the aftermath of trauma. He will outline a framework for therapeutic interventions that facilitate posttraumatic growth through a way of relating called expert companionship. This approach to practice incorporates a broad view of what constitutes trauma, including many experiences that are not typically considered traumatic in our current diagnostic system, but which are traumatic to people because they challenge core beliefs about oneself, other people, the future, and the kind of world in which we live. The attention paid to possibilities for transformation of individuals and their relationships does not preclude working on typical symptoms of trauma, but recognizes that symptoms are better understood, tolerated, and reduced when traumatic suffering can have meaning and purpose.

2. Discover at least three ways to create opportunities for children to communicate during everyday routines
3. Learn how to coach families to embed strategies during their daily routines and activities
From Communication to Conversations: Expanding Language Development in the E...milfamln
Children’s language use grows dramatically throughout the toddler and preschool years. Words and phrases expand daily and children begin to form sentences that go beyond sharing their preferences. Their speech sounds continue to develop and include both predictable, and sometimes adorable, error patterns. Pre-literacy skills also emerge during this developmental window and lay the foundation for academic success as children approach elementary school. In this webinar, the presenters will discuss decontextualized language, early developing morphemes, timelines for phonological processes, and preliteracy achievements during the preschool years as well as when to worry that a child’s speech and language doesn’t seem to be progressing as expected.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

6. Assessing Energy Needs - RMR
• Indirect calorimetry
• Mifflin-St. Jeor
– Males: RMR = 10W + 6.25H – 5A +5
– Females: RMR = 10W + 6.25H – 5A – 161
• Cunningham
– RMR = 370 + 21.6FFM
• Owen
– Female athletes: RMR = 50.4 + 21.1W
Where W is weight in kg, H is height in cm, A is age, and FFM is fat free mass in kg
6
7. Assessing Energy Needs - TDEE
• Use Physical Activity Levels (PAL) to
account for normal daily activities
• Utilize Metabolic Equivalents (METs) to
account for exercise
7
8. METs
• Ratio of working metabolic rate to resting
metabolic rate
– Oxygen uptake in ml/kg/min
– 1 MET = 3.5 ml/kg/min O2 = 1 kcal/kg/hour
• Does not account for body composition,
age, sex, environment, etc.
– Not a perfect estimate of energy cost

9. Using METs
MET x kg x hr
75 kg patient who spends 30 minutes running
7.5 mph
–METs: 11.8 kcal/kg/hr
–11.8 kcal/kg/hr x 75 kg x 0.5 hr = 443 kcal

10. Using METs
MET x kg x hr
65 kg patient completing an Army Physical
Fitness Test (14 min 2 mile)
–METs: 8 kcal/kg/hr (calisthenics); 12.3 kcal/kg/hr (run)
–8 kcal/kg/hr x 65 kg x 0.05 = 25 kcal
–12.3 kcal/kg/hr x 65 x 0.23 = 184 kcal
–25 kcal + 184 kcal = 209 kcal

11. Assessing Macronutrient Needs
Protein
•1.2-1.4 g/kg for endurance
•1.4-1.7 g/kg for strength
•1.5-2 g/kg for weight loss or
injury
Fat
•1 g/kg for most athletes
•2 g/kg for endurance
•3 g/kg for ultraendurance
Carbohydrate
•3-5 g/kg for light training
•5-7 g/kg for moderate training
•6-10 g/kg for 1-3 hours
moderate- to high-intensity
•8-12 g/kg for 4+ hours
moderate- to high-intensity
11
13. Macronutrient Timing
Carbohydrates
Adequate intake benefits both endurance and
stop-and-go sports
•1-4 g/kg 1-4 hours prior to prolonged activity
•1-2 hr → 30 g/hr, 2-3 hr → 60 g/hr, 2.5+ hr → ≤90 g/hr
•Replenish with 1-1.2 g/kg/hr for 4 hours after activity if
multiple daily activity sessions
– Meeting goal daily CHO intake is adequate for one session a day

15. Assessing Micronutrient Needs
15
• Typically similar to non-athlete needs
• Vitamin D >40 ng/ml may be associated with
better performance
• Sweating may increase electrolyte needs
– Cl, Na, K, Ca, Mg
– May use sweat patch to assess
• Iron deficiency is a risk for females
• Some nutrient needs increase at altitude
Licensed by J Chilek from AdobeStock
16. Alcohol
• Metabolism
– Impairs glycogen storage
– Decreases muscle protein
synthesis
• Thermoregulation
– Delays rehydration
– Increases peripheral vasodilation
• Skills/balance
– Impaired motor skills & strength/power
up to 72 hours after intake
• Injury/illness
– Depresses immune function & delays
healing

18. Dietary Trends - Paleo
• Diet modeled after foods available for Paleolithic humans
– Include grass-fed meat/organs, seafood, most fresh
fruits/veggies, eggs, nuts/seeds, certain oils
– Exclude grains, legumes, dairy, refined sugar, potatoes,
processed food, refined vegetable oils, salt
– Hard to find consistent definition/rules
• Many health claims
– Short-term may have health benefits;
risk of deficiency long-term
• Expensive
• Lack of research in athletes
18
Licensed by J Chilek from AdobeStock
19. Dietary Trends – IIFYM
• Freedom to eat whatever fits into your daily
macronutrient needs
• Can be high-effort
• Risk of nutrient deficiency
• Ensure appropriate macronutrient distribution
19
20. Dietary Trends - IF
• Limit intake or fasting for a period (16-24+
hours) with refeed periods
– Ramadan most frequently studied
• Does result in energy restriction for most
• May require strategic fueling for some
athletes
20
21. Dietary Trends - Ketogenic
• Diet focused on fueling from fats rather than carbs
– High fat, adequate protein, low carb (4:1 fat to
protein+carb)
• Many health claims
– Short-term changes in arteries, lipid panel
• Requires time commitment to “adapt”; cannot cheat
• Drastic weight fluctuations when starting/stopping
• No performance benefit/performance decrements
– May make calorie intake easier for some athletes
– Inadequate protein for strength athletes
• Future research: gut flora

performance benefit from intensified training in elite race walkers. The Journal of Physiology. 2017;595(9):2785-2807.
21
Licensed by J Chilek from AdobeStock
22. Dietary Trends – Train Low
• Exercising in a glycogen-depleted state to enhance
fat oxidation
– 2-a-days, training fasted, training without exogenous
CHO
• Perform glycogen-reducing activity followed by
higher intensity activity
• Designed for endurance training (<70%VO2 max) –
not high intensity or resistance exercise
• Results in metabolic changes but limited
performance changes

cardio 20 min 3x/week (5.3 METs)
– Goal of gaining muscle mass/strength with limited body fat gain
• Desk job with some walking (PAL ~ 1.5)
• RMR: 1730 kcal (BodPod), 1805 (Cunningham), 1610
(Mifflin St. Jeor), 1670 (HB)
• Nutrition Rx: 3100-3200 kcal, 360-506 g carbohydrate,
101-123 g protein, 72 g fat
– Nutrition Rx from “nutritionist”: 250 g carbohydrate, 250 g protein, 60 g fat
• Back-check to make sure macros fit into calorie needs
