ECONOMIC FEASIBILITY OF USING BRUSH CONTROL TO ENHANCE OFF-SITE WATER YIELD

A feasibility study of brush for off-site water yield was undertaken in 1998 on the North Concho River near San Angelo, Texas. Subsequently, studies were conducted on eight additional Texas watersheds. Economic analysis was based on estimated control costs of the different options compared to the estimated rancher benefits of brush control. Control costs included initial and follow-up treatments required to reduce brush canopy to between 3 and 8%, and maintain it at the reduced level for 10 years. The state cost-share was estimated by subtracting the present value of rancher benefits from the present value of the total cost of the control program. The total cost of additional water was determined by dividing the total state cost-share if all eligible acreage were enrolled by the total added water estimated to result from the brush control program. This procedure resulted in present values of total control costs per acre ranging from $33.75 to$159.45. Rancher benefits, based on the present value of the improved net returns to typical cattle, sheep, goat, and wildlife enterprises, ranged from $8.95 to$52.12 per acre. Present values of the state cost-share per acre ranged from $21.70 to$138.85. The cost of added water estimated for the eight watersheds ranged from $16.41 to$204.05 per acre-foot averaged over each watershed.Resource /Energy Economics and Policy,

Teaching Tone: Utilizing Writing Center Coaching in First-Year Composition Peer Review

Many first-year writing students represent writing assignments as distinct moments or “discreet units,” as described by composition scholar N. Sommers (2013, p. 10). In these cases, the comments provided on the papers by teachers, classmates, or tutors are applicable only to that one instance of fixing the paper as opposed to being applied to the student writer’s past, present, and future writing occasions. Because of this tendency to isolate writing occasions, teachers must work to make instruction stick for the long run and be a “bridge” to other writing assignments, as opposed to only applying the material to the one instance of the paper (p. 10). This IRB-approved study examines qualitative survey data about peer review from one semester of a first-year writing class and the partnering writing center. Results indicate that students connected peer review to error hunting, which implies that feedback is about a single paper, rather than about developing general writing skills. Recommendations based on this study include shifting peer review to include “encouraging tone” and commentary outside of the paper itself, which can result in developing confidence for student writers (p. 6)

Leadership for Emergence: Exploring organisations through a living system lens

In this article, we outline a research project with adolescent-focused NGOs (non-government organisations) in Christchurch, New Zealand. This project involved 25 managers who used appreciative inquiry process methodology to explore their leadership practices, beliefs, and values. Throughout the article, we construct a conceptual leadership frame for fostering the emergence of adaptive, innovative and responsive organisational capacity that allows organisations to more readily adapt to the complex and changing conditions in which they operate. We describe this frame as a living system lens that is based on viewing organisations as complex adaptive systems of the kind readily found in the natural world. We go on to outline the leaders’ reflections as they drew strong connections between the dynamics found in complex adaptive systems and their own organisations. Proactive mentoring, fostering interaction and shared learning, strategies for distributing power and decentralising control, and exploration and articulation of deeply held values emerged as the key leadership enactments that these leaders implemented in their roles

Reasoned action approach and compliance with recommended behaviours to prevent the transmission of the SARS‐CoV‐2 virus in the UK

Objectives To examine associations between demographics, people’s beliefs, and compliance with behaviours recommended by the UK government to prevent the transmission of the SARS‐CoV‐2 virus that causes COVID‐19. Design A two‐wave online survey conducted one week apart during the national lockdown (April, 2020). Measures A sample of 477 UK residents completed baseline measures from the reasoned action approach (experiential attitudes, instrumental attitudes, injunctive norms, descriptive norms, capacity, autonomy, and intention) and perceived susceptibility for each of the following recommended behaviours: limiting leaving home, keeping at least 2 m away from other people when outside and when inside shops, not visiting or meeting friends or other family members, and washing hands when returning home. Self‐reported compliance with each of the recommended behaviours was assessed one week later. Results Rates of full compliance with the recommended behaviours ranged from 31% (keeping at least 2 m away from other people when inside shops) to 68% (not visiting or meeting friends or other family members). Capacity was a significant predictor of compliance with each of the five recommended behaviours. Increasing age and intentions were also predictive of compliance with three of the behaviours. Conclusions Interventions to increase compliance with the recommended behaviours to prevent the transmission of the SARS‐CoV‐2 virus, especially those relating to social distancing, need to bolster people’s intentions and perceptions of capacity. This may be achieved through media‐based information campaigns as well as environmental changes to make compliance with such measures easier. Such interventions should particularly target younger adults

Transcriptome Analysis of Gene Expression Provides New Insights into the Effect of Mild Therapeutic Hypothermia on Primary Human Cortical Astrocytes Cultured under Hypoxia

Hypothermia is increasingly used as a therapeutic measure to treat brain injury. However, the cellular mechanisms underpinning its actions are complex and are not yet fully elucidated. Astrocytes are the most abundant cell type in the brain and are likely to play a critical role. In this study, transcriptional changes and the protein expression profile of human primary cortical astrocytes cultured under hypoxic conditions for 6 h were investigated. Cells were treated either with or without a mild hypothermic intervention 2 h post-insult to mimic the treatment of patients following traumatic brain injury (TBI) and/or stroke. Using human gene expression microarrays, 411 differentially expressed genes were identified following hypothermic treatment of astrocytes following a 2 h hypoxic insult. KEGG pathway analysis indicated that these genes were mainly enriched in the Wnt and p53 signaling pathways, which were inhibited following hypothermic intervention. The expression levels of 168 genes involved in Wnt signaling were validated by quantitative real-time-PCR (qPCR). Among these genes, 10 were up-regulated and 32 were down-regulated with the remainder unchanged. Two of the differentially expressed genes (DEGs), p38 and JNK, were selected for validation at the protein level using cell based ELISA. Hypothermic intervention significantly down-regulated total protein levels for the gene products of p38 and JNK. Moreover, hypothermia significantly up-regulated the phosphorylated (activated) forms of JNK protein, while downregulating phosphorylation of p38 protein. Within the p53 signaling pathway, 35 human apoptosis-related proteins closely associated with Wnt signaling were investigated using a Proteome Profiling Array. Hypothermic intervention significantly down-regulated 18 proteins, while upregulating one protein, survivin. Hypothermia is a complex intervention; this study provides the first detailed longitudinal investigation at the transcript and protein expression levels of the molecular effects of therapeutic hypothermic intervention on hypoxic human primary cortical astrocytes. The identified genes and proteins are targets for detailed functional studies, which may help to develop new treatments for brain injury based on an in-depth mechanistic understanding of the astrocytic response to hypoxia and/or hypothermia

Simulation support for internet-based energy services

The rapidly developing Internet broadband network offers new opportunities for deploying a range of energy, environment and health-related services for people in their homes and workplaces. Several of these services can be enabled or enhanced through the application of building simulation. This paper describes the infrastructure for e-services under test within a European research project and shows the potential for simulation support for these services

Selling your Design Ideas: 45 Seconds or Less

Fashion companies are using social media and other quick communication tools to promote merchandise, share ideas and create a following among customers. With the rapid means to share ideas and visuals considered to be normal and expected, we need to help our students learn to promote their ideas and themselves this way. To help students train for using the quick promotion technique, we reduced their product line presentation time from the traditional three to five minute presentations using Prezi©, or PowerPoint© to 30 to 45 second sound bites. When the assignment was first given several students did not think it was possible to get across all the information they wanted to in such a short time, and felt they needed more time to share about their work. During the in-class presentation times, we listened, learned, and were informed through short stories, poems, and several radio-like short \u27jingles.\u2

Moderating effects of pro-environmental self-identity on pro-environmental intentions and behaviour: a multi-behaviour study

Self-identity is considered as a useful additional predictor in the theory of planned behaviour (TPB). However, previous research generally assessed the impact of pro-environmental self-identity in relation to single behaviours and no studies considered its potential role in moderating the impact of other predictors on behaviour. The present research used a within-persons approach to examine effects across behaviours and a longitudinal design to assess the moderating role of self-identity in the prediction of intentions and behaviours, controlling for past behaviour. Participants (N = 240) completed Time 1 questionnaires measuring TPB constructs in relation to five different pro-environmental behaviours. Two weeks later, participants (N = 220) responded to a questionnaire assessing self-reports of these behaviours during the intervening two-week period. Across pro-environmental behaviours the findings showed that pro-environmental self-identity significantly moderated the impact of perceived behavioural control on intentions and the effect of past behaviour on both intentions and behaviours
