Problem-Based Teacher-Mentor Education: Fostering Literacy Acquisition in Multicultural Classrooms

We designed a professional development (PD) teacher-mentor program that used problem-based learning (PBL) to accomplish two goals. First, teachers explored how PBL could be used effectively in their classrooms to change the way they think about teaching to include literacy development in content areas. Second, PBL was the basis for PD training to help them improve their own knowledge of PBL, become mentors to other teachers, and implement PBL in their schools across content areas. Educators in the United States are challenged to teach linguistically and culturally diverse (LCD) students with differing literacy levels. The demographics of U.S. classrooms require a rigorous attempt to engage LCD students through collaborative, active learning opportunities (McGroarty, 1998; U.S. Department of Education, 2015). Research shows that literacy learning for all students improves in classroom settings that take a cooperative, student-centered approach (McGroarty, 1988, 1989; NCSS, 1991; Shumway, Saunders, Stewardson, & Reeve, 2001). PBL provides opportunities for students to engage in active learning and allows students with multiple learning styles to negotiate contextualized meaning through a variety of collaborative tasks. PBL has also been shown to be an effective method for teaching learners to be self-directed problemsolvers. However, in the absence of PD and ongoing support, teachers are often resistant to the implementation of PBL. In our program, we used PBL to help teachers learn more about literacy and PBL while providing opportunities for PD and support. As a result, the teacher reflections, discussions, presentations, and self-evaluations demonstrated how, by using PBL in their classrooms while immersing themselves in evidence-based content, they observed enhanced student collaboration. Teachers felt that they were better able to foster a learning environment in their classrooms that would allow students to develop literacy skills in a content-rich context both because of the incorporation of PBL and because of the support they provided for each other. This idea can be easily adapted to foster teacher development and mentoring programs in other fields

Memes as Means: Using Popular Culture to Enhance the Study of Literature

Artistic response is the process by which readers create concrete representations of their transactions with a text through artistic means, including visual arts (e.g. drawing, sculpture, and painting), drama, and music. Research has shown that artistic response helps students form meaningful relationships with texts, as it is a tool that encourages students to enter, explore, make connections, and enjoy stories and characters. In this article we describe an artistic response strategy that we developed and implemented. Recognizing that today’s students often know and interact with the world through social media and memes, we draw on this cultural tool to leverage the power of this platform and its familiarity and appeal to our student

Ceftaroline fosamil monotherapy for methicillin-resistant Staphylococcus aureus bacteremia: a comparative clinical outcomes study

OBJECTIVES: Vancomycin is the treatment of choice for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia; however, its use has been subject to scrutiny due to failure in severe infections. Ceftaroline fosamil (CPT-F) is approved for MRSA acute bacterial skin and skin structure infections, but not for bloodstream infections. The clinical outcomes of treatment with CPT-F in patients with MRSA bacteremia were evaluated. METHODS: Patients diagnosed with MRSA bacteremia at Henry Ford Hospital in Detroit, Michigan, USA, involving isolates with a vancomycin minimum inhibitory concentration ≥1.0mg/l and susceptible in vitro to CPT-F, were systematically reviewed retrospectively. Ceftaroline fosamil-treated patients were matched with at least two vancomycin- and/or one daptomycin-treated control patient based on age-patients age 65 years or greater or less than 65 years of age. Outcomes evaluated included the duration of hospitalization, duration of therapy, adverse events, relapse, hospital readmission, and death. RESULTS: Thirty consecutive cases of MRSA bacteremia treated with CPT-F during the period May 2011 to June 2013 were identified; these patients were matched to 56 MRSA bacteremia patients treated with vancomycin and 46 MRSA bacteremia patients treated with daptomycin. The primary source of MRSA bacteremia in the cohort treated with CPT-F was endocarditis (n=7, 23%), skin/wound (n=9, 30%), and bone/joint (n=8, 27%). The MRSA bacteremia in those treated with CPT-F was community-acquired in 43% of cases, healthcare-associated in 43%, and hospital-acquired in 13%. The mean length of hospital stay for these patients was 22 days. The overall 30-day mortality rate was 13% (n=4) in CPT-F patients versus 24% (n=11) in daptomycin patients and 11% (n=6) in vancomycin patients (p=0.188). CONCLUSIONS: CPT-F demonstrated comparable clinical outcomes in MRSA bacteremia patients compared with the other agents, especially as salvage therapy

Pds5p regulates the maintenance of sister chromatid cohesion and is sumoylated to promote the dissolution of cohesion

Pds5p and the cohesin complex are required for sister chromatid cohesion and localize to the same chromosomal loci over the same cell cycle window. However, Pds5p and the cohesin complex likely have distinct roles in cohesion. We report that pds5 mutants establish cohesion, but during mitosis exhibit precocious sister dissociation. Thus, unlike the cohesin complex, which is required for cohesion establishment and maintenance, Pds5p is required only for maintenance. We identified SMT4, which encodes a SUMO isopeptidase, as a high copy suppressor of both the temperature sensitivity and precocious sister dissociation of pds5 mutants. In contrast, SMT4 does not suppress temperature sensitivity of cohesin complex mutants. Pds5p is SUMO conjugated, with sumoylation peaking during mitosis. SMT4 overexpression reduces Pds5p sumoylation, whereas smt4 mutants have increased Pds5p sumoylation. smt4 mutants were previously shown to be defective in cohesion maintenance during mitosis. These data provide the first link between a protein required for cohesion, Pds5p, and sumoylation, and suggest that Pds5p sumoylation promotes the dissolution of cohesion

Carbon dioxide and ocean acidification observations in UK waters. Synthesis report with a focus on 2010–2015

Key messages: 1.1 The process of ocean acidification is now relatively well-documented at the global scale as a long-term trend in the open ocean. However, short-term and spatial variability can be high. 1.2 New datasets made available since Charting Progress 2 make it possible to greatly improve the characterisation of CO2 and ocean acidification in UK waters. 3.1 Recent UK cruise data contribute to large gaps in national and global datasets. 3.2 The new UK measurements confirm that pH is highly variable, therefore it is important to measure consistently to determine any long term trends. 3.3 Over the past 30 years, North Sea pH has decreased at 0.0035±0.0014 pH units per year. 3.4 Upper ocean pH values are highest in spring, lowest in autumn. These changes reflect the seasonal cycles in photosynthesis, respiration (decomposition) and water mixing. 3.5 Carbonate saturation states are minimal in the winter, and lower in 7 more northerly, colder waters. This temperature-dependence could have implications for future warming of the seas. 3.6 Over the annual cycle, North-west European seas are net sinks of CO2. However, during late summer to autumn months, some coastal waters may be significant sources. 3.7 In seasonally-stratified waters, sea-floor organisms naturally experience lower pH and saturation states; they may therefore be more vulnerable to threshold changes. 3.8 Large pH changes (0.5 - 1.0 units) can occur in the top 1 cm of sediment; however, such effects are not well-documented. 3.9 A coupled forecast model estimates the decrease in pH trend within the North Sea to be -0.0036±0.00034 pH units per year, under a high greenhouse gas emissions scenario (RCP 8.5). 3.10 Seasonal estimates from the forecast model demonstrate areas of the North Sea that are particularly vulnerable to aragonite undersaturation
