    Ecology and systematics of mangrove crabs of the genus <i>Perisesarma</i> (Crustacea: Brachyura: Sesarmidae) from East Africa

    East Africa has a reduced mangrove crab species richness when compared to Asian mangroves. To date, only one species of Perisesarma de Man, 1895 has been reported in East Africa, despite more than 30 years of mangrove research in this region. Based on morphology, colour, mtDNA and behaviour, we describe a new species of Perisesarma from Kenya, P. samawati sp. nov. Surprisingly, when comparing molecular data from other species within this genus,P. samawati sp. nov. and the sympatric P. guttatum (A. Milne Edwards, 1869) are not sister species. Some aspects of the ecology of P. guttatum and P. samawati sp. nov. are compared and the differences discussed. Additionally, we compare P. samawati sp. nov. with the ecological literature of a possible sister species P. eumolpe de Man, 1895 from Malaysian mangroves. Our findings suggest that the new species is an ecologically important species in East African mangroves

    Reading: A Preprimer for Parents

    Get PDF
    The purpose of this project is to plan a booklet for parents which will provide them with some background information on the reading process and methods and approaches to reading instruction, along with some specific suggestions of ways they can help their children learn to read. Also included is a teacher\u27s supplement for directions and suggested implementation. The booklet is designed for parents of students in the primary grades who are beginning readers. It is intended to be used in conjunction with a parent-teacher conference or a small group meeting of parents and teacher. It is hoped that the meeting would provide for clarification of any questions, serve as a motivator to parents, and allow them to exchange ideas and suggestions for utilizing this booklet. More personal situations concerning students would be discussed at follow-up parent-teacher conferences

    The Effectiveness of an Anesthesia Handoff Tool: An Electronic Health Record Application to Enhance Patient Safety

    Perioperative patient care handoffs are complex and multidimensional and require accurate attention to detail. Communication failures among healthcare providers increase the risk of morbidity and mortality. Utilizing a standardized handoff tool located within the electronic anesthesia record formalizes the handoff process and improves patient safety. Prior to the introduction of the Electronic Anesthesia Handoff Tool, 82 patient care transfer observations were conducted; subsequent to the launch of the tool, 75 patient care transfer observations were conducted, and then before and after comparisons were made. Descriptive statistics, a two-tailed t-test, and Spearman’s correlations were conducted. Alpha level was set at p \u3c 0.05. There were significantly (p\u3c .05) fewer errors made in all categories of patient information following the introduction of the Electronic Anesthesia Handoff Tool. Though there were trends towards more omissions occurring after 3:00 p.m., the difference in most patient information categories was not significant (p\u3c .05). In addition, there were no differences in omissions related to the severity of patient co-morbidities based on patients’ American Society of Anesthesiologists physical status classification. This study provided information regarding the incidence of patient information inaccuracies and omissions during patient care transfer before and after implementation of an electronic patient care transfer tool

    The Effect of Misinformation on the Delay of Climate Legislation; Economic and Environmental Solutions to Make Environmental Progress in the Absence of Political Support

    Get PDF
    The scientific community has come to a consensus that climate change is anthropogenic yet the American public is lagging in understanding and acceptance. While the scientific community has tried to spread this information to the public, scientific misinformation propels a narrative that climate science is untrustworthy and inaccurate, and portrays an overrepresented side of climate change deniers to the climate debate. Misinformation is spread by harming scientist\u27s reputations, curating fake science, lobbying, investing in organizations that have prominent and previously trusted names, and most importantly, by spreading doubt about scientific findings. Because misinformation (coupled with lobbying) motivates an anti-environmental policy mindset in our elected officials, bills are challenging to pass. We must work without this legislation by promoting environmental solutions that also have economic benefits that attract the support of investors as well as elected officials. These solutions include the promotion of individual investment in renewable energy, an increase in green employment, and an increase in carbon capture and other technologies that utilize released carbon to make profitable products. These solutions have the potential to strengthen our economy while working towards a green economy

    Assessing elemental ratios as a paleotemperature proxy in the calcite shells of patelloid limpets

    Get PDF
    Archaeological shell and fish middens are rich sources of paleoenvironmental proxy data. Patelloid limpet shells are common constituents in archaeological middens found along European, African, and South American coastlines. Paleotemperature reconstructions using oxygen isotope ratios of limpet shells depend on the ability to constrain the oxygen isotope ratio of seawater; therefore, alternative proxies are necessary for coastal localities where this is not possible. The study evaluates whether Mg/Ca, Sr/Ca, Li/Ca, Li/Mg, and Sr/Li ratios are reliable proxies of sea surface temperature (SST) in the calcite layer of shells of the patelloid limpets, Patella vulgata and Nacella deaurata. We compare Mg/Ca, Sr/Ca, Li/Ca, Li/Mg, and Sr/Li ratios to the seasonal variations in contemporaneous δ18Oshell values, which primarily record seasonal changes in SST. Elemental ratios (Mg/Ca, Sr/Ca, Li/Ca, Li/Mg, and Sr/Li) show no significant correlations with reconstructed SST in P. vulgata and N. deaurata shells, nor do they show sinusoidal cycles expected from a SST proxy. In addition, shell δ13C values show no significant ontogenetic trends, suggesting that these limpets exhibit little change in metabolic carbon incorporation into the shell with increasing ontogenetic age. Although shell growth rate exhibits a logarithmic decrease with age based on calculated linear extension rates, growth rate does not correlate with elemental profiles in these limpets. Overall, ele
