PBIS Implementation and Sustainability: Primary Educatorsâ Perspectives of Success
Today the school-wide behavior management program, Positive Behavioral Interventions and Supports, or PBIS, follows the Multi-Tiered Systems of Support (MTSS) framework when addressing students with behavior challenges in general education classrooms. PBIS provides a collaborative framework of problem solving and evidence-based strategies, thus proactively meeting studentsâ overall needs. The purpose of this study is to fill a gap in the literature pertaining to teacher perspectives of using PBIS practices in their classroom across this framework. This dissertation further details implications for training and professional development concerning school-wide PBIS as well as the organizational structures necessary for success in the classroom. As a result, this study analyzes teacher perspectives of PBIS classroom implementation, challenges, and successes, taking place in one K-8 school. Administrative and problem solving teams support and professional development were examined across three primary educators. Meaningful data was then generated describing how teachers perceive the PBIS processes implemented in their classrooms.

Total synthesis and biological evaluation of the tetramic acid based natural product harzianic acid and its stereoisomers
Financial support for this project was provided by Cancer Research UK (Grant No. C21383/A6950)The bioactive natural product harzianic acid was prepared for the first time in just six steps (longest linear sequence) with an overall yield of 22%. The identification of conditions to telescope amide bond formation and a Lacey-Dieckmann reaction into one pot proved important. The three stereoisomers of harzianic acid were also prepared, providing material for comparison of their biological activity. While all of the isomers promoted root growth, improved antifungal activity was unexpectedly associated with isomers in the enantiomeric series opposite that of harzianic acid.Publisher PDFPeer reviewe
Redescription of Cervidellus vexilliger (de Man, 1880) Thorne, 1937 (Nematoda : Cephalobidae) and taxonomical consequences
#Cervidellus vexilliger, actuellement espÚce type du genre #Ypsylonellus, est redécrit et un néotype est désigné parmi les spécimens d'un échantillon collecté dans la localité type : Haagse Bos, Pays-Bas. Une autre espÚce trÚs proche, correspondant à la diagnose de #C. neftasiensis, était également présente dans cet échantillon. La description originale de #C. vexilliger et les nouveaux spécimens provenant de la localité type suggÚrent que #C. vexilliger est conspécifique de #C. serratus. #C. serratus est donc synonymisé avec #C. vexilliger et #Ypsilonellus est synonymisé avec #Cervidellus. Des diagnoses différentielles et une classification provisoire sont proposées pour les genres #Cervidellus et #Stegelletina. (Résumé d'auteur

A multistep continuous flow synthesis machine for the preparation of pyrazoles via a metal-free amine-redox process
A versatile multistep continuous flow setup is reported for the four-step conversion of anilines into
pyrazole products. The synthesis machine incorporates the use of amine-redox chemistry through diazotization and a metal-free vitamin C mediated reduction. The machine can be used for the synthesis of an array of analogues or the scale up of an individual target
Expression profiling of snoRNAs in normal hematopoiesis and AML
Key Points
A subset of snoRNAs is expressed in a developmental- and lineage-specific manner during human hematopoiesis. Neither host gene expression nor alternative splicing accounted for the observed differential expression of snoRNAs in a subset of AML.</jats:p
Molecular epidemiologic investigations of Mycoplasma gallisepticum conjunctivitis in songbirds by random amplified polymorphic DNA analyses.
An ongoing outbreak of conjunctivitis in free-ranging house finches (Carpodacus mexicanus) began in 1994 in the eastern United States. Bacterial organisms identified as Mycoplasma gallisepticum (MG) were isolated from lesions of infected birds. MG was also isolated from a blue jay (Cyanocitta cristata) that contracted conjunctivitis after being housed in a cage previously occupied by house finches with conjunctivitis, and from free-ranging American goldfinches (Carduelis tristis) in North Carolina in 1996. To investigate the molecular epidemiology of this outbreak, we produced DNA fingerprints of MG isolates by random amplification of polymorphic DNA (RAPD). We compared MG isolates from songbirds examined from 1994 through 1996 in 11 states, representing three host species, with vaccine and reference strains and with contemporary MG isolates from commercial poultry. All MG isolates from songbirds had RAPD banding patterns identical to each other but different from other strains and isolates tested. These results indicate that the outbreak of MG in songbirds is caused by the same strain, which suggests a single source; the outbreak is not caused by the vaccine or reference strains analyzed; and MG infection has not been shared between songbirds and commercial poultry
Making intelligent cities in Europe climate-neutral: About the necessity to integrate technical and socio-cultural innovations
Smart urban futures are currently being tested and promoted in Europe using innovative and intelligent urban technologies at different spatial scales, in individual sectors such as energy or transport, or by using specific technological innovations. However, the great transformation, though often called for and widely advocated, is yet to come. This paper discusses the necessity of promoting integrative approaches that go beyond technology-centered solutions with the aim of opening up paths towards urban climate neutrality: Precisely because urban futures are hardly predictable due to diverse and partly still hidden influencing factors, it is important to include especially socio-cultural innovations, as well as resilient technical solutions. The considerations developed in this regard conclude with a presentation of the contributions in this TATuP special topic.Smarte urbane ZukĂŒnfte werden derzeit in Europa unter dem Einsatz innovativer und intelligenter urbaner Technologien auf unterschiedlichen rĂ€umlichen Skalierungsebenen, in einzelnen Sektoren wie Energie oder Verkehr bzw. anhand spezifischer technologischer Erneuerungen erprobt und vorangetrieben. Allerdings steht die vielfach beschworene groĂe Transformation in den StĂ€dten noch aus. Dieser Beitrag diskutiert die Notwendigkeit, ĂŒber technikzentrierte Lösungen hinausgehende integrative AnsĂ€tze zu fördern, um Wege hin zur urbanen KlimaneutralitĂ€t zu eröffnen: Gerade weil urbane ZukĂŒnfte angesichts vielfĂ€ltiger und teils noch verborgener Einflussfaktoren kaum vorhersagbar sind, gilt es, neben resilienten technischen Lösungen, insbesondere soziokulturelle Innovationen einzubeziehen. Die hierzu entwickelten Ăberlegungen schlieĂen mit einer Vorstellung der BeitrĂ€ge in diesem TATuP-Thema ab
