Applying TLC (a Targeted Learning Community) to Transform Teaching and Learning in Science

This article describes the development of a Targeted Learning Community (TLC) that supports first-year science students enrolled in a General Chemistry course. Drawing on student feedback and knowledge and expertise in their respective disciplines, four faculty members from two colleges at Kennesaw State University came together to develop a learning community that would prevent early attrition in the science majors and increase student metacognition. In this paper, the design of the TLC is presented, and the effect it had on faculty vitality is discussed. Ruth A. Goldfine is Chair of the Department of First-Year and Transition Studies at Kennesaw State University in Kennesaw, GA. Hillary H. Steiner (Assistant Professor of Educational Psychology) and Stephanie M. Foote (Associate Professor of Education and Director of the Master of Science in First Year Studies) are also members of the Department of First-Year and Transition Studies at Kennesaw State University.

Impact of Age at Pediatric Stroke on Long-term Cognitive Outcome.

OBJECTIVES To investigate the impact of age at pediatric arterial ischemic stroke on long-term cognitive outcome in order to identify patients particularly at risk for the development of cognitive long-term cognitive sequelae. METHODS This cross-sectional study included patients in the chronic phase of stroke (> 2 years after stroke) previously diagnosed with neonatal or childhood arterial ischemic stroke and a control group. Participants with active epilepsy, severe learning difficulties, or behavioral problems hindering the cognitive assessment were excluded. Several cognitive domains, including intelligence, executive functions (working memory, inhibition, and cognitive flexibility), processing speed, memory, letter fluency, and visual-motor skills were assessed with neuropsychological tests. Cognitive long-term outcome was compared across patients after neonatal stroke (stroke between 0 and 28 days of life), early childhood stroke (stroke between 29 days and < 6 years) and late childhood stroke (stroke between ≥ 6 and < 16 years). RESULTS 52 patients after neonatal or childhood arterial ischemic stroke (median age: 15.3 years, IQR = 10.6 - 18.7) and 49 healthy controls (median age: 13.6 years, IQR = 9.8 - 17.2) met the inclusion criteria. Cognitive outcome was significantly worse in the pediatric stroke group compared to the control group. A non-linear effect of age at stroke (irrespective of lesion size and lesion location) was found for cognitive flexibility, processing speed, and verbal learning with early childhood stroke (29 days to < 6 years) showing significantly worse cognitive outcome compared to neonatal or late childhood stroke (p < .05, FDR-corrected). CONCLUSION Age at stroke is an important factor for post-stroke recovery and modulates long-term cognitive outcome irrespective of lesion size and lesion location. Children after early childhood stroke are at particular risk for alterations of long-term cognitive functions

Characterization of site-specific vegetation activity in Alaskan wet and dry tundra as related to climate and soil state

We present discrete (2-h resolution) multi-year (2008–2017) in situ measurements of seasonal vegetation growth and soil biophysical properties from two sites on Alaska\u27s North Slope, USA, representing dry and wet sedge tundra. We examine measurements of vertical active soil layer temperature and soil moisture profiles (freeze/thaw status), woody shrub vegetation physiological activity, and meteorological site data to assess interrelationships within (and between) these two study sites. Vegetation phenophases (cold de-hardening start, physiological function start, stem growth start, stem growth end, physiological function end, cold hardening completion) were found to have greater interannual day of year (DOY) occurrence variability at the dry site compared with the wet site. At the dry site, vegetation activity begins on average ~7 days earlier and ends ~11 days earlier. The mean active stem growth window lasts ~54 days for the dry site and ~51 days for the wet site. Vegetation, in both tundra environments, began cold de-hardening functions (warm season prep) prior to atmospheric temperatures warming above 0°C. Similar results were found related to the critical soil freeze/thaw/transition dates; the dry site had a DOY phenophase occurrence range that was 8 days larger than that of the wet site. A longer continuous summer thaw period was captured at the wet site by ~26 days throughout the active layer. In addition, the dry site was measured to have longer spring and fall soil isothermal conditions than the wet site by ~9 and 5 days throughout the active layer. These results show that the dry site\u27s willow shrub vegetation physiology and soil condition phenology is more variable than the wet site. Alongside the in situ data, a remote sensing product from NASA\u27s MEaSUREs program was utilized; our research indicates that the AMSR-derived satellite product is more precise over the wet tundra site with critical date alignment between remote sensing observations and in situ measurements ranging from ~4 to 11 days. Furthermore, the AMSR product was shown to preemptively estimate land surface condition change during the spring transition for both tundra types while lagging during the fall transition and freeze-up periods

Enhanced clarity and holism: The outcome of implementing the ICF with an acute stroke multidisciplinary team in England

This article is made available through the Brunel Open Access Publishing Fund.Purpose: Although it is recommended that the ICF (International Classification of Functioning, Disability and Health) should be implemented to aid communication within multidisciplinary stroke services, there is no empirical evidence to demonstrate the outcomes of such implementation. Working with one stroke service, this project aimed to address this gap and sought to evaluate the outcomes of implementing an ICF-based clinical tool into practice. Method: Using an action research framework with mixed methods, data were collected from individual interviews, a focus group, questionnaires, email communications, minutes from relevant meetings and field notes. Thematic analysis was undertaken, using immersion and crystallisation, to define overall themes. Descriptive statistics were used to analyse quantitative data. Data from both sources were combined to create key findings. Results: Three findings were determined from the data analysis. The ICF (1) fosters communication within and beyond the multidisciplinary stroke team; (2) promotes holistic thinking; and (3) helps to clarify team roles. Conclusions: The ICF enhanced clarity of communication and team roles within the acute stroke multidisciplinary team as well as with other clinicians, patients and their relatives. In addition, the ICF challenged stroke clinicians to think holistically, thereby appropriately extending their domain of concern beyond their traditional remit. Implications for Rehabilitation: (1) The ICF is a globally accepted framework to describe functioning and is in use in a variety of clinical settings. Yet, the outcomes of using it in clinical practice have yet to be fully explored. (2) This study found that the ICF enhanced clarity of communication and team roles within an acute stroke multidisciplinary team and to others beyond the team, including clinicians, patients and their relatives. (3) Using the ICF also challenged clinicians to think holistically about patient needs following a stroke.The Elizabeth Casson Trus

Organizing Online Events

This is a compilation of over 100 slides which were presented in different block courses on Organizing Online Events that were attended by colleagues and members of The Africa Multiple Cluster of Excellence at the University of Bayreuth. Each of them was tailored for different events and attendees – from new student assistants to professors of partner institutions. We used Zoom Meetings and Zoom Webinars, but also administrative platforms and OBS and Restream for streaming onto other platforms. Most courses were structured into eight modules, comprising Basics, Installation of Zoom Webinars/Meetings, Recording, Streaming, Mixed Formats, (internal) Administrative Tasks, Problem Management, and After the Event. Some modules are designed for beginners, some for experienced colleagues

Cu2ZnSn(S,Se)4 from CuxSnSy nanoparticle precursors on ZnO nanorod arrays

Solar cells with Cu2ZnSnS4 absorber thin films have a potential for high energy conversion efficiencies with earth-abundant and non-toxic elements. In this work the formation of CZTSSe from CuxSnSy nanoparticles (NPs) deposited on ZnO nanorod (NR) arrays as precursors for zinc is investigated. The NPs are prepared using a chemical route and are dispersed in toluene. The ZnO NRs are grown on fluorine doped SnO2 coated glass substrates by electro deposition method. A series of samples are annealed at different temperatures between 300 °C and 550 °C in selenium containing argon atmosphere. To investigate the products of the reaction between the precursors the series is analyzed by means of X-ray diffraction (XRD) and Raman spectroscopy. The morphology is recorded by scanning electron microscopy (SEM) images of broken cross sections. The XRD measurements and the SEM images show the disappearing of ZnO NRs with increasing annealing temperature. Simultaneously the XRD and Raman measurements show the formation of CZTSSe. The formation of secondary phases and the optimum conditions for the preparation of CZTSSe is discusse

Adherence to the Mediterranean Diet and Incidence of Pre-Frailty and Frailty in Community-Dwelling Adults 70+: The 3-Year DO-HEALTH Study

The Mediterranean diet has been associated with many health benefits. Therefore, we investigated whether the degree of adherence to the Mediterranean diet at baseline, or changes in adherence over time, were associated with the incidence of pre-frailty or frailty in generally healthy older adults. This study used the DO-HEALTH trial data. We evaluated Mediterranean diet adherence with Panagiotakos’ MedDietScore at baseline and at 3-year follow-up; frailty was assessed annually with the Fried frailty phenotype. We used minimally and fully adjusted mixed logistic regression models to estimate the exposure–disease relationship. We included 1811 participants without frailty at baseline (mean age 74.7 years; 59.4% women). Baseline adherence, as reflected by the MedDietScore, was not associated with becoming pre-frail [OR(95%CI) = 0.93 (0.83–1.03) for five-point greater adherence] or frail [OR(95%CI) = 0.90 (0.73–1.12) for five points]. However, a five-point increase in the MedDietScore over three years was associated with lower odds of becoming pre-frail [OR(95%CI) = 0.77 (0.68–0.88)] and frail [OR(95%CI) = 0.77 (0.64–0.92)]. In generally healthy and active older adults, baseline adherence to the Mediterranean diet was not associated with the incidence of pre-frailty or frailty over a 3-year follow-up. However, improved adherence to the Mediterranean diet over time was associated with significantly lower odds of becoming pre-frail or frail
