    Get PDF
    Pay parity for early childhood educators is critical to reducing turnover, improving job quality, and achieving an equitable child care system. This publication explores compensation reform nationwide and offers ideas for local and state financing options to better support the early childhood workforce and New York families.https://educate.bankstreet.edu/bsec/1013/thumbnail.jp

    Green Polymer Chemistry: Investigating the Mechanism of Radical Ring-Opening Redox Polymerization (R3P) of 3,6-Dioxa-1,8-octanedithiol (DODT)

    The mechanism of the new Radical Ring-opening Redox Polymerization (R3P) of 3,6-dioxa-1,8-octanedithiol (DODT) by triethylamine (TEA) and dilute H2O2 was investigated. Scouting studies showed that the formation of high molecular weight polymers required a 1:2 molar ratio of DODT to TEA and of DODT to H2O2. Further investigation into the chemical composition of the organic and aqueous phases by 1H-NMR spectroscopy and mass spectrometry demonstrated that DODT is ionized by two TEA molecules (one for each thiol group) and thus transferred into the aqueous phase. The organic phase was found to have cyclic disulfide dimers, trimers and tetramers. Dissolving DODT and TEA in water before the addition of H2O2 yielded a polymer with Mn = 55,000 g/mol, in comparison with Mn = 92,000 g/mol when aqueous H2O2 was added to a DODT/TEA mixture. After polymer removal, MALDI-ToF MS analysis of the residual reaction mixtures showed only cyclic oligomers remaining. Below the LCST for TEA in water, 18.7 °C, the system yielded a stable emulsion, and only cyclic oligomers were found. Below DODT/TEA and H2O2 1:2 molar ratio mostly linear oligomers were formed, with \u3c20% cyclic oligomers. The findings support the proposed mechanism of R3P. http://dx.doi.org/10.3390/molecules2004650

    A Snapshot of ECE Apprenticeship Programs

    This publication offers a closer look at the key features of existing apprenticeship programs across the United States—such as the diversity and range of approaches to credentials, partnership models, funding, and how programs deliver quality mentoring and/or coaching support—to reimagine how program quality can be strengthened to deepen learning for participants.https://educate.bankstreet.edu/bsec/1012/thumbnail.jp

    Caudal Polymorphism and Cephalic Morphology among First-Stage Larvae of \u3ci\u3eParelaphostrongylus odocoilei\u3c/i\u3e (Protostrongylidae: Elaphostrongylinae) in Dall’s Sheep from the Mackenzie Mountains, Canada

    We demonstrate polymorphism in the structure of the tail among first-stage larvae of Parelaphostrongylus odocoilei (Protostrongylidae). Two distinct larvae, both with a characteristic dorsal spine, include (1) a morphotype with a kinked conical tail marked by three distinct transverse folds or joints and a symmetrical terminal tail spike and (2) a morphotype with a digitate terminal region lacking folds or joints and with an asymmetrical, subterminal tail spike. These divergent larval forms had been postulated as perhaps representing distinct species of elaphostrongyline nematodes. Application of a multilocus approach using ITS-2 sequences from the nuclear genome and COX-II sequences from the mitochondrial genome confirmed the identity of these larvae as P. odocoilei. Additionally, based on scanning electron microscopy (low-temperature field emission), the cephalic region of these larvae consisted of a cuticular triradiate stoma surrounded by six single circumoral papillae of the inner circle, ten papillae of the outer circle (four paired and two single), and two lateral amphids. Ours is the first demonstration of structural polymorphism among larval conspecifics in the Metastrongyloidea and Strongylida. The basis for this polymorphism remains undetermined, but such phenomena, if discovered to be more widespread, may contribute to continued confusion in discriminating among first-stage larvae for species, genera, and subfamilies within Protostrongylidae

    Research-Practice Partnerships as Community-Engaged Learning: Lessons Learned from a Collaborative Project with Youth Development Programs

    Get PDF
    To bridge the gap between community-engaged learning and research-practice partnerships, we describe our experiences in a project jointly conceptualized and implemented by undergraduate students and youth development practitioners over the course of two academic semesters. The project offered students the opportunity to apply the skills they learned through coursework in a way that also supported the needs of community practitioners, providing both groups with opportunities to learn from each other. In this paper we describe the collaborative project, our process, the challenges we faced, and the impact of the project on the student researchers and the youth development practitioners. Written by representatives of both the student researchers and the practitioner collaborators, we hope this paper will inspire others to incorporate students in research-practice partnerships and that our reflections on the strengths and challenges of this process will facilitate more effective implementation of community-engaged scholarship in the future

    Trichinella pseudospiralis in a wolverine (Gulo gulo) from the Canadian North

    Get PDF
    Species of Trichinella are a globally distributed assemblage of nematodes, often with distinct host ranges, which include people, domestic, and wild animals. Trichinella spp. are important in northern Canada, where dietary habits of people and methods of meat preparation (drying, smoking, fermenting as well as raw) increase the risk posed by these foodborne zoonotic parasites. Outbreaks in the arctic and subarctic regions of Canada and the United States are generally attributed to T. nativa (T2) or the T6 genotype, when genetic characterization is performed. We report the discovery of Trichinella pseudospiralis (T4), a non-encapsulated species, in a wolverine (Gulo gulo) from the Northwest Territories of Canada. This parasite has been previously reported elsewhere from both mammals and carnivorous birds, but our findings represent new host and geographic records for T. pseu- dospiralis. Multiplex PCR and sequencing of fragments of Cytochrome Oxidase Subunit I (COI) and D3 rDNA confirmed the identification. Phylogenetically, Canadian isolates linked with each other and others derived from Palearctic or Neotropical regions, but not elsewhere in the Nearctic (continental USA). We suggest that mi- gratory birds might have played a role in the dispersal of this pathogen 1000\u27s of km to northwestern Canada. Wolverines are not typically consumed by humans, and thus should not pose a direct food safety risk for tri- chinellosis. However, the current finding suggests that they may serve as an indicator of a broader distribution for T. pseudospiralis. Along with infection risk already recognized for T. nativa and Trichinella T6, our observa- tions emphasize the need for further studies using molecular diagnostics and alternative methods to clarify if this is a solitary case, or if T. pseudospiralis and other freeze susceptible species of Trichinella (such as T. spiralis) circulate more broadly in wildlife in Canada, and elsewhere

    Promoting general practice in medical schools. Where are we now?

    Get PDF
    In November 2016, the Medical Schools Council and Health Education England published a joint report chaired by Professor Val Wass: ‘By choice – not by chance’ to raise the profile of general practice as a positive career choice for medical students. We sought to evaluate the impact of the report by firstly, asking the views of Heads of GP teaching at UK medical schools whether and how the report has supported them in raising the profile of general practice and secondly, describing the initiatives developed by medical schools in a national survey. There was a perception reported by heads of GP teaching that the report has been highly influential in facilitating the promotion of general practice as a career to medical students. We describe multiple specific initiatives developed in response to the report’s recommendations. The national survey confirmed that whilst there is significant variation across medical schools in their response to the specific recommendations in the report, definite progress is being made. A number of areas that need particular consideration have been highlighted and we would recommend that future surveys are completed at appropriate time intervals to review further progress
