Reframing Behaviour to Foster Safe and Supporting Schools

This Organizational Improvement Plan (OIP) examines educator support to students who present with chronically challenging behaviours. Educators are experiencing an increase in the frequency and severity of interfering student behaviours affecting classroom learning, school climate, and educator mental well-being (RRDSB, 2018a, 2019b; Santor et al., 2019). Educators frequently disengage from these students and their discipline is managed by administration (RRDSB, 2019b). These students, often already members of marginalized communities (Bailey, 2015), are further marginalized by the use of exclusionary, punitive measures. This mandates a social justice framework that benefits from the moral dialogue evoked by transformative leadership (Shields, 2018). In conjunction, an ecological systems (Bronfenbrenner, 1977) approach that highlights student environment, in contrast to the culture of power and privilege of most educators (Delpit, 1988), is required. Nadler and Tushman’s (1989) Congruence Model highlights the gap between Board system values and lived experiences in schools. Reframing the faulty notion that challenging behaviour is a student choice (Greene, 2014b, 2016; Levinsky, 2016) and reframing the purpose of education as human development (Tranter et al., 2018) for a socially just world (Weiner, 2003) is foundational to implementation. The OIP uses the Change Path Model (Cawsey et al., 2016) as the blueprint upon which to layer a plan that addresses educator mindset and skill development. The use of Hord et al.’s (1987) Concerns Based Adoption Model to value educator emotion and fidelity of practice compliments an authentic and adaptive leadership approach

ForestSim model of impacts of smallholder dynamics: forested landscapes of the Upper Peninsula of Michigan

Many forested landscapes in the United States contain a large number of small private landowners (smallholders). The individual decisions of these smallholders can collectively have a large impact on the structure, composition, and connectivity of forests. While models have been developed to try to understand this large-scale collective impact, few models have incorporated extensive information from individual decision-making. Here we introduce an agent-based model, infused with sociological data from smallholders, overlaid on a GIS layer to represent individual smallholders, and used to simulate the impact of thousands of harvesting decisions. Our preliminary results suggest that certain smallholder characteristics (such as relative smallholder age and education level as well as whether a smallholder is resident or absentee) and information flow among owners can radically impact forests at the landscape scale. While still in its preliminary stages, this modeling approach is likely to demonstrate in detail the consequences of decision-making due to changing smallholder demographics or new policies and programs. This approach can help estimate the effectiveness of programs based on landscape-scale programmatic goals and the impact of new policy initiatives

Enrollment decision-making in U.S. forestry and related natural resource degree programs

This article investigates enrollment decision-making trends among students currently enrolled in forestry and related natural resource (FRNR) degree programs in the United States. We conducted an online survey administered to all student participants attending the Society of American Foresters (SAF) National Convention in Salt Lake City, UT, in 2014 to obtain our enrollment decision-making data. Students were asked to rank the enrollment factors they considered most important to their decision to enroll, and factors that caused them to hesitate when enrolling in their degree program. We found that the “typical” FRNR enrollee was a person who enjoyed being outdoors and had an affinity toward nature, while being attracted to the idea of working outdoors on subject material that pertained to nature in general. We also found that there were many important differences between the “typical” FRNR enrollee and their minority counterparts. For example, women were found to be significantly more hesitant about enrolling in a FRNR program than males (the dominant demographic of FRNR students). In addition to these differences, we found critical differences between degree program and specialty that also crossed gender lines. We report the results of these findings and discuss the implications for future recruitment efforts geared toward both boosting FRNR enrollment overall as well as increasing FRNR student diversity

Enrollment Decision-Making by Students in Forestry and Related Natural Resource Degree Programmes Globally

A survey of 396 undergraduate and graduate students from 51 countries on 5 continents currently enrolled in Forestry or Related Natural Resource (FRNR) degree programmes was conducted of attendees to the International Union of Forest Research Organizations\u27 (IUFRO) conference in Salt Lake City, Utah, 2014. These perspectives come from some of the most active students in their respective fields. We explored the motivating reasons for enrolling in their current FRNR programme, and conversely why they may have been hesitant to do so. Results indicate that enjoyment of nature was the most important factor on average driving the decision to enroll, closely followed by job satisfaction, concern for the environment, enjoyment of outdoor recreation, being outdoors, and an interest in subject material. Hesitancy factors included earning potential, availability of funding/scholarships, and politically contentious issues. A number of significant differences were found across demographic categories. Of particular note was the greater hesitancy on the part of women and people of color to enroll in FRNR degree programmes compared to their white male counterparts. We discuss the limitations of our study arising from its international scope and imbalance of responses among countries and regions. HIGHLIGHTS Forestry and Related Natural Resources (FRNR) students from 51 countries report that enjoyment of nature was the most important factor driving their decision to enroll. Decision factors that caused hesitation included earning potential, availability of funding, and political issues. Importance factors differed significantly between genders, race/ethnicity, academic standing, world region, and social background (i.e. urban vs rural). Women and people of color from multiple world regions had a greater hesitancy to enroll in an FRNR programme than their white male counterparts. Implications for recruitment and retention include the need for continual diversity and inclusion efforts and a balance between personal preferences and employability

The development of 3-D, in vitro, endothelial culture models for the study of coronary artery disease

The response of the vascular endothelium to wall shear stress plays a central role in the development and progression of atherosclerosis. Current studies have investigated endothelial response using idealized in vitro flow chambers. Such cell culture models are unable to accurately replicate the complex in vivo wall shear stress patterns arising from anatomical geometries. To better understand this implication, we have created both simplified/tubular and anatomically realistic in vitro endothelial flow models of the human right coronary artery. A post-mortem vascular cast of the human left ventricular outflow tract was used to create geometrically accurate silicone elastomer models. Straight, tubular models were created using a custom made mold. Following the culture of human abdominal aortic endothelial cells within the inner lumen, cells were exposed to steady flow (Re = 233) for varying time periods. The resulting cell morphology was analyzed in terms of shape index and angle of orientation relative to the flow direction. In both models a progressive elongation and alignment of the endothelium in the flow direction was observed following 8, 12, and 24 hours. This change, however, was significantly less pronounced in the anatomical model (as observed from morphological variations indicative of localized flow features). Differences were also observed between the inner and outer walls at the disease-prone proximal region. Since morphological adaptation is a visual indication of endothelial shear stress activation, the use of anatomical models in endothelial genetic and biochemical studies may offer better insight into the disease process

Influence of Sacubitril/Valsartan (LCZ696) on 30-day readmission after heart failure hospitalization

Background: Patients with heart failure (HF) are at high risk for hospital readmission in the first 30 days following HF hospitalization. Objectives: This study sought to determine if treatment with sacubitril/valsartan (LCZ696) reduces rates of hospital readmission at 30-days following HF hospitalization compared with enalapril. Methods: We assessed the risk of 30-day readmission for any cause following investigator-reported hospitalizations for HF in the PARADIGM-HF trial, which randomized 8,399 participants with HF and reduced ejection fraction to treatment with LCZ696 or enalapril. Results: Accounting for multiple hospitalizations per patient, there were 2,383 investigator-reported HF hospitalizations, of which 1,076 (45.2%) occurred in subjects assigned to LCZ696 and 1,307 (54.8%) occurred in subjects assigned to enalapril. Rates of readmission for any cause at 30 days were 17.8% in LCZ696-assigned subjects and 21.0% in enalapril-assigned subjects (odds ratio: 0.74; 95% confidence interval: 0.56 to 0.97; p = 0.031). Rates of readmission for HF at 30-days were also lower in subjects assigned to LCZ696 (9.7% vs. 13.4%; odds ratio: 0.62; 95% confidence interval: 0.45 to 0.87; p = 0.006). The reduction in both all-cause and HF readmissions with LCZ696 was maintained when the time window from discharge was extended to 60 days and in sensitivity analyses restricted to adjudicated HF hospitalizations. Conclusions: Compared with enalapril, treatment with LCZ696 reduces 30-day readmissions for any cause following discharge from HF hospitalization

Relation of vertebral deformities to bone density, structure, and strength.

Because they are not reliably discriminated by areal bone mineral density (aBMD) measurements, it is unclear whether minimal vertebral deformities represent early osteoporotic fractures. To address this, we compared 90 postmenopausal women with no deformity (controls) with 142 women with one or more semiquantitative grade 1 (mild) deformities and 51 women with any grade 2-3 (moderate/severe) deformities. aBMD was measured by dual-energy X-ray absorptiometry (DXA), lumbar spine volumetric bone mineral density (vBMD) and geometry by quantitative computed tomography (QCT), bone microstructure by high-resolution peripheral QCT at the radius (HRpQCT), and vertebral compressive strength and load-to-strength ratio by finite-element analysis (FEA) of lumbar spine QCT images. Compared with controls, women with grade 1 deformities had significantly worse values for many bone density, structure, and strength parameters, although deficits all were much worse for the women with grade 2-3 deformities. Likewise, these skeletal parameters were more strongly associated with moderate to severe than with mild deformities by age-adjusted logistic regression. Nonetheless, grade 1 vertebral deformities were significantly associated with four of the five main variable categories assessed: bone density (lumbar spine vBMD), bone geometry (vertebral apparent cortical thickness), bone strength (overall vertebral compressive strength by FEA), and load-to-strength ratio (45-degree forward bending ÷ vertebral compressive strength). Thus significantly impaired bone density, structure, and strength compared with controls indicate that many grade 1 deformities do represent early osteoporotic fractures, with corresponding implications for clinical decision making

An improved continuous compositional-spread technique based on pulsed-laser deposition and applicable to large substrate areas

A new method for continuous compositional-spread (CCS) thin-film fabrication based on pulsed-laser deposition (PLD) is introduced. This approach is based on a translation of the substrate heater and the synchronized firing of the excimer laser, with the deposition occurring through a slit-shaped aperture. Alloying is achieved during film growth (possible at elevated temperature) by the repeated sequential deposition of sub-monolayer amounts. Our approach overcomes serious shortcomings in previous in-situ implementations of CCS based on sputtering or PLD, in particular the variations of thickness across the compositional spread and the differing deposition energetics as function of position. While moving-shutter techniques are appropriate for PLD-approaches yielding complete spreads on small substrates (i.e. small as compared to distances over which the deposition parameters in PLD vary, typically about 1 cm), our method can be used to fabricate samples that are large enough for individual compositions to be analyzed by conventional techniques, including temperature-dependent measurements of resistivity and dielectric and magnetic and properties (i.e. SQUID magnetometry). Initial results are shown for spreads of (Sr,Ca)RuO$_3$.Comment: 6 pages, 8 figures, accepted for publication in Rev. Sci. Instru
