Review of Reading Strategies for Students with Learning Disabilities

The purpose of this paper is to examine a sampling of research on reading disabilities and intervention strategies. Five articles were reviewed and a summary and analysis of each is included. A plethora of information exists in education claiming to be the one stop solution for students with reading difficulties. It is important to recognize that many well researched methods have been around for a number of years and continue help students make gains. In other words it is important for educators not to abandon proven methods and change pedagogy every time a new idea surfaces. The paper will conclude with a discussion of the common themes found in the research and the implications for school leaders faced with choices and challenges related to students with difficulties in the area of reading

Kinder Camp Provides Reading Ramp : A Study to Examine the Effects of Summer Learning Loss on Beginning Readers

This study was designed to determine if twenty days of reading intervention would have an impact on preventing summer learning loss for students entering first grade. Research indicates that while all students show some losses each summer, students with limited resources, commonly referred to as economically disadvantaged, suffer greater losses. This study showed evidence of reducing summer learning loss for students in the participant group at an urban school district in central Virginia. The data in this study supports the body of literature that indicates that summer quality programming is important and can have an impact on reducing summer learning loss for students, especially students in poverty

Variación estacional de la biomasa y abundancia del mesozooplancton y herbivoría de copépodos en el Cantábrico central (Sur del Golfo de Vizcaya)

Size fractionated mesozooplankton biomass, abundance and copepod grazing were investigated over an annual cycle (1998) at two stations off Cudillero (central Cantabrian Sea). Mesozooplankton biomass was higher in summer/early autumn, reaching ~3000 mg dw m-2 in September. Copepods were the most abundant taxonomic group, representing 91 and 81% of the total mesozooplankton abundance in the coastal and shelf-break station respectively. Copepod gut contents were higher in summer at the coastal station, while the shelf-break station showed maximum gut contents in April. Gut contents were linearly related to integrated chlorophyll, except in the case of large animals at the shelf break station. Copepod community carbon ingestion was higher from June to September at both stations, reaching a maximum value of ~165 mg C m-2 day-1. Calculated grazing rates translates into an average daily consumption values of 8.7% (coast) and 5.25% (shelf-break) of total chlorophyll stock, or 20% (shelf-break) of total primary production.A lo largo del año 1998, se estudió la biomasa y abundancia del mesozooplancton (en distintas fracciones de tamaño) así como la ingestión de la comunidad de copépodos en dos estaciones cercanas a Cudillero (Mar Cantábrico). La biomasa del mesozooplancton presentó sus valores más elevados en verano y a principios del otoño, alcanzando máximos de ~3000 mg Peso Seco m-2 en Septiembre. Los copépodos fueron el grupo taxonómico más abundante, representando el 91% y el 81% de la abundancia total del mesozooplancton en las estaciones de costa y talud respectivamente. El contenido estomacal de los copépodos en la estación costera fue más elevado durante el verano, mientras que en la estación situada sobre el talud, el contenido estomacal más elevado se encontró en el mes de Abril. Se encontró una relación lineal entre el contenido estomacal de los copépodos y el valor de clorofila integrado en la columna de agua, excepto en el caso de los copépodos grandes en la estación de talud. La ingestión de carbono de la comunidad de copépodos fue más elevada entre Junio y Septiembre en ambas estaciones, alcanzando valores máximos de ~165 mg C m-2 día-1. La ingestión de la comunidad de copépodos representa un consumo diario del 8.7 % (costa) y 5.25 % (talud) de la clorofila total, y un 20 % (talud) de la producción primaria total

Multispectral Recovery of a Fragment of Richard FitzRalph’s Summa de Questionibus Armenorum from University of Rochester, D.460 1000-03

Multispectral imaging—the process of obtaining image data from a range of both visible and invisible wavelengths—is a new frontier in medieval studies, raising the possibility of recovering damaged or palimpsested texts that have been illegible for centuries. In this paper we show the remarkable results of applying this technology to University of X, MS D.460 1000-003, a previously unidentified single-folio fragment that was gifted to the university in 1968. Formerly used as a limp vellum binding for a seventeenth-century volume, the text has become so worn that it is all but completely unreadable to the naked eye. The fragment has consequently received little scholarly attention prior to our investigation. Our team recovered nearly all of the lost text and identified the fragment as an excerpt from Richard FitzRalph’s Summa de Questionibus Armenorum. Although this text survives in 45 other manuscripts and fragments, our discovery is highly significant because the Rochester fragment is the only copy of any of FitzRalph’s works in a non-European collection. Moreover, the fragment, whose handwriting dates to no later than 1370, may be the oldest extant copy of the Summa by at least half a decade. We present the process of this discovery, our conclusions about the text, and the potential for multispectral imaging to unlock new information hidden in known but understudied fragments held in archival collections around the world

Initial clinical experience with Myxo-ETlogix∗∗Myxo-ETlogix is a trade name of Edwards Lifesciences LLC, Irvine, Calif. mitral valve repair ring

ObjectiveComplexity of mitral valve repair for myxomatous disease has led to low adoption. We report initial experience with a new ring designed specifically for myxomatous disease, the Myxo-ETlogix (Edwards Lifesciences LLC, Irvine, Calif).MethodsFrom March 15, 2006, through November 19, 2007, 129 patients underwent mitral valve surgery for pure myxomatous disease, and 124 valves (96.1%) were repaired. The Myxo-ETlogix ring was used in 100 cases and the Physio ring (Edwards) in 24. The Myxo-ETlogix design includes a 3-dimensional shape to reduce systolic anterior motion and a larger orifice to accommodate elongated leaflets and decrease need for sliding plasty. Direct mitral valve measurements were made. Sizing was based on A2 height, and choice of ring type was based on unresected leaflet heights.ResultsThere was no operative mortality or lasting perioperative morbidity. The Myxo-ETlogix group had taller A2, P1, P2, and P3 leaflet segments than the Physio group (P ≤ .003). Only 1 sliding plasty was performed for asymmetry in the Myxo-ETlogix group. Predischarge and follow-up echocardiograms (n = 338 in 124 patients) disclosed transient nonobstructive chordal systolic anterior motion in 3 echocardiograms in 3 patients. No patients had 2+ or greater mitral regurgitation. At discharge, 5.7% had 1+ mitral regurgitation; this proportion was 17.3% at last follow-up (mean 6.1 ± 4.4 months).ConclusionIn initial experience with the Myxo-ETlogix ring, nonobstructive systolic anterior motion has been rare and obstructive systolic anterior motion not observed. Ongoing prospective echocardiographic and clinical studies will elucidate the role of this etiology-specific ring

Why marine phytoplankton calcify

Calcifying marine phytoplankton - coccolithophores - are some of the most successful yet enigmatic organisms in the ocean, and are at risk from global change. In order to better understand how they will be affected we need to know 'why' coccolithophores calcify. Here we review coccolithophorid evolutionary history, cell biology, and insights from recent experiments to provide a critical assessment of the costs and benefits of calcification. We conclude that calcification has high energy demands, and that coccolithophores might have calcified initially to reduce grazing pressure, but that additional benefits such as protection from photo-damage and viral-bacterial attack further explain their high diversity and broad spectrum ecology. The cost-versusbenefit of these traits is illustrated by novel ecosystem modeling, although conclusive observations are still limited. In the future ocean, the trade-off between changing ecological and physiological costs of calcification and their benefits will ultimately decide how this important group is affected by ocean acidification and global warming

Multicentre, prospective, open study to evaluate the safety and efficacy of hylan G-F 20 in knee osteoarthritis subjects presenting with pain following arthroscopic meniscectomy

The aim of the study was to evaluate the safety and efficacy of viscosupplementation with hylan G-F 20 in patients with mild to moderate osteoarthritis (OA) presenting with persistent knee pain 4–12 weeks after arthroscopic meniscectomy. A prospective, multi-centre, open study was carried out in patients with pain due to OA of the knee, not resolved by simple analgesics, 4–12 weeks after undergoing arthroscopic meniscectomy. To be eligible, patients had to score ≥50 mm and ≤90 mm on both walking pain and patient global assessment visual analogue scales (VAS; 0–100 mm) at baseline and be radiologically diagnosed pre-operatively with OA grade I or II on the Kellgren-Lawrence scale, with <50% joint space narrowing. Patients received three intra-articular, 2 ml injections of hylan G-F 20 in the target knee with an interval of 1 week between injections, and were followed for 52 weeks. The primary efficacy endpoint was the change from baseline in the walking pain VAS score at 26 weeks. Secondary outcome measures were the walking pain VAS scores at all other time points, the WOMAC Index at all time points, and patient and physician global assessment at all time points. The safety of the treatment was assessed using adverse event (AE) reports. A total of 62 patients (mean age 55.4 years, 52% male) were enrolled. The mean walking pain VAS score decreased by 36.8 mm from baseline at 26 weeks (P < 0.0001), and also showed statistically significant decreases (P < 0.0001) at all other time points. The change in WOMAC total and subscale scores from baseline were statistically significant (P < 0.0001) at all time points, as were the decreases in the physician and patient global assessment VAS scores. There were 18 target knee AEs (mostly pain and/or swelling and/or effusion) in 12 patients (19%) considered to be at least possibly related to treatment. The majority of these (78%) were mild or moderate in intensity. One patient (1.6%) experienced a serious adverse event (synovitis) in the target knee that was considered possibly related to study treatment. Hylan G-F 20 provides effective pain relief and improves stiffness and physical function in patients with mild to moderate OA presenting with persistent osteoarthritic pain 4–12 weeks after arthroscopic meniscectomy. Symptomatic efficacy was maximised at 12 weeks and maintained at 26 and 52 weeks. The type (pain and/or swelling and/or effusion) and the intensity (mostly mild/moderate) of AEs reported in this study are similar to those reported in other trials in different patient populations, but the incidence was higher (19%). The risk/benefit of hylan G-F 20 in this particular population of patients is favourable

SeaWiFS Postlaunch Technical Report Series

This report documents the scientific activities on board the Royal Research Ship (RRS) James Clark Ross (JCR) during the fifth Atlantic Meridional Transect (AMT-5), 14 September to 17 October 1997. There are three objectives of the AMT Program. The first is to derive an improved understanding of the links between biogeochemical processes, biogenic gas exchange, air-sea interactions, and the effects on, and responses of, oceanic ecosystems to climate change. The second is to investigate the functional roles of biological particles and processes that influence ocean color in ecosystem dynamics. The Program relates directly to algorithm development and the validation of remotely-sensed observations of ocean color. Because the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) instrument achieved operational status during the cruise (on 18 September), AMT-5 was designated the SeaWiFS Atlantic Characterization Experiment (SeaACE) and was the only major research cruise involved in the validation of SeaWiFS data during the first 100 days of operations. The third objective involved the near-real time reporting of in situ light and pigment observations to the SeaWiFS Project, so the performance of the satellite sensor could be determined

Salp contributions to vertical carbon flux in the Sargasso Sea

We developed a one-dimensional model to estimate salp contributions to vertical carbon flux at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic subtropical gyre for a 17-yr period (April 1994 to December 2011). We based the model parameters on published rates of salp physiology and experimentally determined sinking and decomposition rates of salp carcasses. Salp grazing was low during non-bloom conditions, but routinely exceeded 100% of chlorophyll standing stock and primary production during blooms. Fecal pellet production was the largest source of salp carbon flux (78% of total), followed by respiration below 200 m (19%), sinking of carcasses (3%), and DOC excretion below 200 m (\u3c 0.1%). Thalia democratica, Salpa fusiformis, Salpa aspera, Wheelia cylindrica, and Iasis zonaria were the five highest contributors, accounting for 95% of total salp-mediated carbon flux. Seasonally, salp flux was higher during spring-summer than fall-winter, due to seasonal changes in species composition and abundance. Salp carbon export to 200 m was on average 2.3 mg C m(-2) d(-1) across the entire time series. This is equivalent to 11% of the mean 200 m POC flux measured by sediment traps in the region. During years with significant salp blooms, however, annually-averaged salp carbon export was the equivalent of up to 60% of trap POC flux at 200 m. Salp carbon flux attenuated slowly, and at 3200 m the average modeled carbon from salps was 109% of the POC flux measured in sediment traps at that depth. Migratory and carcass carbon export pathways should also be considered (alongside fecal pellet flux) as facilitating carbon export to sequestration depths in future studies. Published by Elsevier Ltd
