Post-Plea Appeal of Dispositive Issues: There’s Glory for You

Denna studies syfte var att undersöka hur rektorer, trä- och metallslöjdlärare och hem- och konsumentkunskapslärare tar sig an utmaningen ”hållbar utveckling” i skolan och i respektive ämne. För att ta reda på detta har jag utgått från en kvalitativ metodansats där jag intervjuat fyra rektorer och sex lärare i ämnena trä- och metallslöjd och hem- och konsumentkunskap. Rektorer och lärare delade med sig om sina tankar kring begreppet ”hållbar utveckling” och vad begreppet betydde för dem personligen. Ambitionen är hög hos samtliga att hinna med allt som ska hinnas med inom de ramar de har på skolorna, men rektorer och lärare är dåligt insatta i vad läroplanen, lgr 11, säger om ”hållbar utveckling”. Rektorer och lärare nämner tidsbrist, ekonomi och brist på inspiration som anledning till att det inte arbetas med området. Lärarna i hem- och konsumentkunskap arbetar mer aktivt med miljöarbetet än lärarna i trä- och metallslöjd trots att båda ämnena har lika stora möjligheter att göra detta. Samtliga lärare vill ha mer stöd i form av utbildning i ämnet ”hållbar utveckling” och även ekonomiskt stöd för att kunna utföra sitt uppdrag i att ge eleverna, men ber inte om stöd eftersom de inte tror sig kunna få något stöd

Innovation Adoption and Diffusion in Synchronous Tutoring Owls: A Cross-Contextual Case Study Using Diffusion of Innovations Theory

Synchronous online tutoring shares many attributes with face-to-face tutoring such as real-time, document collaboration, and conversational cues provided by audio and video, yet writing center professionals know seemingly little about synchronous tutoring OWLs due to the lack of formal publications about synchronous online tutoring coupled with the prevailing paradigm that seeks to transfer face-to-face tutoring practices to online synchronous tutoring, which overshadows the innovation processes taking place in synchronous OWLs. The purpose of this study was to document emergent practices in the use of two different synchronous tutoring technologies and the processes by which those practices were adopted and implemented in each OWL, using the theoretical framework of Diffusion of Innovations (DOI). A qualitative, case-study methodology was used to explore the contextual-based knowledge of tutors and writing center directors within each case. Several DOI principles emerged to explain the relationship between the prevailing face-to-face paradigm and the selection, reinvention, and adoption of each synchronous tutoring technology and its related tutoring practices. The findings suggest that writing center professionals could benefit from enhancing their understanding of DOI’s social system concept and its symbiotic relationship with the established roles of metaphor and previous experience in synchronous tutoring innovations

The effects of a community-facilitated reinforcement system on barking in shelter dogs

Behavioral problems are one of the most prevalent causes of dogs entering animal shelters. The current rate of euthanasia in shelters in the United States, 670,000 euthanasia-caused deaths per year, is influenced by undesirable behaviors. The behaviors the animals engage in while at the shelter also play a role in whether or not potential adopters will find the animals desirable or undesirable. Unfortunately, dogs who exhibit socially inappropriate behavior are more likely to be subjected to euthanasia than dogs who behave in ways that are socially acceptable. Analyses of shelter dog behavior has focused on increasing adoptability by teaching socially appropriate responses. However, research is lacking for treatments aimed at reducing the problem behavior of dogs; more specifically, barking. Shelter environmental alteration programs, respondent conditioning procedures, and functional analyses of the targeted problem behavior of these animals have all been conducted. However, minimal research exists for the reduction of barking in shelter dogs. This proposed study looked to bridge the gap between the literature by conducting an empirical analysis of a community-facility reinforcement system aimed at reducing barking levels in the kennel area of a local animal shelter. The results indicated that baseline during the by Appointment Only phase was the most effective at decreasing barking. Furthermore, adoption rates from the baseline in the by Appointment Only phase were the highest of all the phases. Implications of the findings and future research are discussed

Effect of Rooibos and Honeybush Tea Extracts Against Botrytis cinerea

Green tea extracts from the indigenous South African rooibos (Aspalathus linearis) and honeybush (Cyclopia species)plants were evaluated as potential antifungal agents against the plant pathogen Botrytis cinerea. When applied at 10mg/ml, the tea extracts stimulated biomass production in B. cinerea by more than 3-fold after 24 hrs. This inductioncould not be linked directly to the presence of selected micro- and macronutrients or antioxidants in the extracts,suggesting a complex set of yet unidentified factors that may act synergistically to enhance cell growth. However,when applied at 100 mg/ml, the A. linearis and C. genistoides extracts reduced spore germination of B. cinerea by33.3% and 16.7%, respectively. This suggests that the tea extracts contain active compounds that should be furtherinvestigated for their potential as natural anti-fungal agents

The synergistic and neuroprotective effects of alcohol–antioxidant treatment on blood–brain barrier endothelial cells

Background: Alcohol (EtOH) is reported to adversely affect one of the most crucial roles of the blood–brain barrier (BBB), the regulation of its permeability, thereby compromising the stability of the homeostatic environment of the brain. The central component of the BBB, endothelial cells (ECs), regulates BBB transcellular transport, while their paracellular pathways are made virtually impermeable by molecular structures called tight junctions (TJs). These TJs are composed of proteins, such as claudin-5, a protein involved in the regulation of paracellular permeability and of key interest in this study. Methods and Results: The working hypothesis of this study postulated that the high levels of antioxidants (AOs) in the fermented Aspalathus linearis (Rooibos; Rf) tincture may protect the ECs of the BBB against oxidative stress induced by EtOH exposure. Cells were exposed for 24 hours to selected concentrations of EtOH (25 and 100 mM), Rf (containing an antioxidant equivalence of 1.9 nM Aspalathin), and cotreatments of EtOH and Rf. Cell viability, live cell number, and toxicity were analyzed using the trypan blue exclusion assay. RT-qPCR was implemented to quantify claudin-5 transcription. In addition, permeability (Transepithelial Electrical Resistance) of bEnd5 monolayers was measured. The experimental timeline for the above-mentioned parameters was 24 and 48 hours. Conclusions: Our study showed that simultaneous exposure of Rf and EtOH was able to negate the effects of EtOH on cell viability and cell proliferation, but was not able to reverse or reduce the effects of EtOH on claudin-5 transcription and paracellular permeability. Furthermore, a novel finding in this study suggests that very low concentrations of AOs in tinctures such as Rooibos tea could profoundly alter the redox status of brain ECs
