Matthew Baird Journal

Matthew Baird, born in Baltimore, Maryland in 1839 and the oldest child of George W. Baird and Mary Eliza Merrill, was a confederate soldier during the Civil War. He joined the 3rd Infantry, Company E in Grand Rapids, Michigan on May 13, 1861 and reported for duty on June 10, 1861.

Continued Progress: Promising Evidence on Personalized Learning

The findings are grouped into four sections. The first section on student achievement finds that there were positive effects on student mathematics and reading performance and that the lowest-performing students made substantial gains relative to their peers. The second section on implementation and the perceptions of stakeholders finds that adoption of personalized learning practices varied considerably. Personalized learning practices that are direct extensions of current practice were more common, but implementation of some of the more challenging personalized learning strategies was less common. The third section relates implementation features to outcomes and identifies three elements of personalized learning that were being implemented in tandem in the schools with the largest achievement effects. Finally, the fourth section compares teachers' and students' survey responses to a national sample and finds some differences, such as teachers' greater use of practices that support competency-based learning and greater use of technology for personalization in the schools in this study with implementation data

Breaking Bad? Gangs, masculinities and murder in Trinidad

The murder rate in Port of Spain, Trinidad, rose dramatically around the turn of the millennium, driven overwhelmingly by young men in gangs in the city’s poor neighborhoods. The literature frequently suggests a causal relationship between gang violence and rising transnational drug flows through Trinidad during this period. However, this is only part of a complex picture and misses the crucial mediating effect of evolving male identities in contexts of pronounced exclusion. Using original data, this article argues that historically marginalized “social terrains” are particularly vulnerable to violence epidemics when exposed to the influence of transnational drug and gun trafficking. When combined with easily available weapons, contextually constructed male hegemonic orders that resonate with the past act as catalysts for contemporary gang violence within those milieus. The study contributes a new empirical body of work on urban violence in Trinidad and the first masculinities-specific analysis of this phenomenon. We argue that contemporary gang culture is a historically rooted, contextually legitimated, male hegemonic street project in the urban margins of Port of Spain

Translating Standardized Effects of Education Programs Into More Interpretable Metrics

Evaluators report effects of education initiatives as standardized effect sizes, a scale that has merits but obscures interpretation of the effects’ practical importance. Consequently, educators and policymakers seek more readily interpretable translations of evaluation results. One popular metric is the number of years of learning necessary to induce the effect. We compare years of learning to three other translation options: benchmarking against other effect sizes, converting to percentile growth, and estimating the probability of scoring above a proficiency threshold. After enumerating the desirable properties of translations, we examine each option’s strengths and weaknesses. We conclude that years of learning performs worst, and percentile gains performs best, making it our recommended choice for more interpretable translations of standardized effects

Formalizing artisanal and small-scale gold mining : A grand challenge of the Minamata Convention

Artisanal and small-scale gold mining (ASGM) is the world's largest source of anthropogenic mercury emissions and releases. These have devastating consequences for miners' health and the environment. Most of the >20 million ASGM miners worldwide are not officially recognized, registered, regulated, or protected by state laws. Formalization-the process of organizing, registering, and reforming ASGM-is mandated by the Minamata Convention on Mercury. Previous attempts to reduce mercury emissions from ASGM have largely failed. Our perspective argues that signatories to the Convention will only succeed in reducing ASGM mercury emissions and releases with comprehensive bottom-up formalization approaches centered around working with miners, and significant external funding from consumers, large mining corporations, and governments. The approximate global 5-year cost of this approach could be US$355 million (upper and lower estimate bounds: US$213-742 million) if scaled per country, or US$808 million (US$248 million-US$2.17 billion) if scaled per miner.Peer reviewe

The Anisakis Transcriptome Provides a Resource for Fundamental and Applied Studies on Allergy-Causing Parasites.

BACKGROUND: Food-borne nematodes of the genus Anisakis are responsible for a wide range of illnesses (= anisakiasis), from self-limiting gastrointestinal forms to severe systemic allergic reactions, which are often misdiagnosed and under-reported. In order to enhance and refine current diagnostic tools for anisakiasis, knowledge of the whole spectrum of parasite molecules transcribed and expressed by this parasite, including those acting as potential allergens, is necessary. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we employ high-throughput (Illumina) sequencing and bioinformatics to characterise the transcriptomes of two Anisakis species, A. simplex and A. pegreffii, and utilize this resource to compile lists of potential allergens from these parasites. A total of ~65,000,000 reads were generated from cDNA libraries for each species, and assembled into ~34,000 transcripts (= Unigenes); ~18,000 peptides were predicted from each cDNA library and classified based on homology searches, protein motifs and gene ontology and biological pathway mapping. Using comparative analyses with sequence data available in public databases, 36 (A. simplex) and 29 (A. pegreffii) putative allergens were identified, including sequences encoding 'novel' Anisakis allergenic proteins (i.e. cyclophilins and ABA-1 domain containing proteins). CONCLUSIONS/SIGNIFICANCE: This study represents a first step towards providing the research community with a curated dataset to use as a molecular resource for future investigations of the biology of Anisakis, including molecules putatively acting as allergens, using functional genomics, proteomics and immunological tools. Ultimately, an improved knowledge of the biological functions of these molecules in the parasite, as well as of their immunogenic properties, will assist the development of comprehensive, reliable and robust diagnostic tools.This work was supported by a ‘Collaborations Across Boundaries’ grant and a seed grant from the Centre of Biodiscovery and Molecular Development of Therapeutics, James Cook University (FJB and CC).
