Reading Strategies in Content Area Math

Since the introduction of the CCSS, expectations in math have placed greater responsibility for problem-solving on students. No longer is computation the primary focus of elementary math instruction; instead the goal has shifted to student understanding of the mathematical contexts. The aim of this action research study, guided by Vygotsky’s theory of social constructivism, was to determine the effectiveness of integrating reading and content area math, while deepening students’ skills in vocabulary, journaling, and visualizing. Nine fifth-grade students receiving Tier 2 math intervention were selected to participate in the study. Data collection consisted of pre and post measures including criterion-referenced math assessment in problem-solving, aligned with the common core. Results showed that from pre to posttesting participants’ mean score increased from 68% correct to 80%, indicating that the integration of reading strategies into math content instruction is effective way for students to increase skill in word problem-solving

Perceptions of Unintended Adolescent Pregnancy: Associations with College Students’ Neoliberal Beliefs and Type of Contraceptive Problem

The purpose of this study was to explore perceptions of unintended adolescent pregnancy as associated with level of neoliberal beliefs and type of contraceptive problem. Northeastern U.S. undergraduate college students (N = 72) completed a measure of neoliberal beliefs and were randomly assigned to read about a couple that became pregnant after contraceptive non-adherence or a contraceptive accident. As expected, observers with greater neoliberal beliefs perceived an unintended adolescent pregnancy as more controllable than those with lesser neoliberal beliefs. Additionally, a pregnancy following a contraceptive accident was perceived as less controllable and elicited more sympathy than a pregnancy following contraceptive non-adherence. These findings suggest perceptions of unintended adolescent pregnancy are both context-dependent and related to the observer’s level of neoliberal beliefs. This knowledge can be applied to promote the well-being of pregnant and parenting adolescents in social service, clinical, and school settings through increased awareness and improved attitudes toward these individuals

Validated Sandwich ELISA for the Quantification of von Willebrand Factor in Rabbit Plasma

von Willebrand Factor (vWF) is a multimeric plasma protein important for platelet plug formation. As part of its haemostatic role, it is released from endothelial cells during vascular stress or injury and is considered an excellent biomarker of endothelial function. Currently, there are no validated kits available to measure vWF in rabbits. We developed a sensitive and reproducible sandwich enzyme-linked immunosorbent assay (ELISA) for detection of vWF in rabbit plasma using commercially available antibodies and reagents. Purified human vWF was used as a calibrator standard with a dynamic range of 1.56–100 ng/mL. The Minimum Required Dilution for rabbit plasma was 1:100. When plasma was spiked with 3.76 or 10 ng/mL vWF, recovery was 108 ± 2% and 93 ± 2%, respectively. Intra- and inter-assay precision for 8 rabbit plasma samples were 3% and 4%, respectively. The Minimum Detectable Concentration was 254 pg/mL for purified human vWF and 1:10,700 dilution of cholesterol-fed rabbit plasma, and the Reliable Detection Limits were 457 pg/mL and 1:5940. Three freeze-thaw cycles significantly decreased vWF concentrations for purified human vWF and 2 of 3 plasma samples assayed. This ELISA provides sensitive and reproducible measurements of rabbit plasma vWF, which is an important biomarker for cardiovascular research

The social ecology of water in a Mumbai slum: failures in water quality, quantity, and reliability

Background: Urban slums in developing countries that are not recognized by the government often lack legal access to municipal water supplies. This results in the creation of insecure “informal” water distribution systems (i.e., community-run or private systems outside of the government’s purview) that may increase water-borne disease risk. We evaluate an informal water distribution system in a slum in Mumbai, India using commonly accepted health and social equity indicators. We also identify predictors of bacterial contamination of drinking water using logistic regression analysis. Methods: Data were collected through two studies: the 2008 Baseline Needs Assessment survey of 959 households and the 2011 Seasonal Water Assessment, in which 229 samples were collected for water quality testing over three seasons. Water samples were collected in each season from the following points along the distribution system: motors that directly tap the municipal supply (i.e., “point-of-source” water), hoses going to slum lanes, and storage and drinking water containers from 21 households. Results: Depending on season, households spend an average of 52 to 206 times more than the standard municipal charge of Indian rupees 2.25 (US dollars 0.04) per 1000 liters for water, and, in some seasons, 95% use less than the WHO-recommended minimum of 50 liters per capita per day. During the monsoon season, 50% of point-of-source water samples were contaminated. Despite a lack of point-of-source water contamination in other seasons, stored drinking water was contaminated in all seasons, with rates as high as 43% for E. coli and 76% for coliform bacteria. In the multivariate logistic regression analysis, monsoon and summer seasons were associated with significantly increased odds of drinking water contamination. Conclusions: Our findings reveal severe deficiencies in water-related health and social equity indicators. All bacterial contamination of drinking water occurred due to post-source contamination during storage in the household, except during the monsoon season, when there was some point-of-source water contamination. This suggests that safe storage and household water treatment interventions may improve water quality in slums. Problems of exorbitant expense, inadequate quantity, and poor point-of-source quality can only be remedied by providing unrecognized slums with equitable access to municipal water supplies

The Health and Economic Costs of Violence against Women and Girls on Survivors, Their Families, and Communities in Ghana

Violence against women and girls (VAWG) is a worldwide phenomenon. Globally, 35% of women have experienced physical or sexual intimate partner violence (IPV) or non-partner sexual violence in their lives. VAWG is estimated to cost the global economy about US$ eight trillion. Most studies on violence in Ghana discuss domestic violence or some forms of sexual violence but lack a comprehensive view of VAWG and its costs and impacts on communities, businesses, and the national economy. Our international consortium undertook a mixed-methods study to estimate the economic and non-economic losses caused by VAWG. We surveyed 2002 women and 805 male and female employees and conducted 24 in-depth interviews (IDIs) and 8 focus group discussions (FGDs). The study finds that costs of VAWG are high and multi-fold. It estimates costs to health, social relationships, and productivity for individuals, their families, and communities. Individual well-being and capabilities are impacted through absenteeism or missed care work and mental health issues. VAWG deepens household poverty by out-of-pocket expenditures that arise to address medical and legal issues that result from violence. Additionally, VAWG affects the vibrancy of communities as women’s participation and leadership decline. These costs accumulate to have profound effects on the Ghanaian economy and society

Meeting Report: The 2nd Annual Argonne Soils Workshop, Argonne National Laboratory, Chicago Illinois, USA, October 6-8, 2010

This report summarizes the proceedings of the 2nd Annual Argonne Soils Workshop held at Argonne National Laboratory October 6–8, 2010. The workshop assembled a diverse group of soil ecologists, microbiologists, molecular biologists, and computational scientists to discuss the challenges and opportunities related to implementation of metagenomics approaches in soil microbial ecology. The overarching theme of the workshop was “designing ecologically meaningful soil metagenomics research”, which encouraged presentations on both ecological and computational topics. The workshop fostered valuable cross-discipline communication and delivered the message that soil metagenomics research must be based on an iterative process between biological inquiry and bioinformatics tools

Brief Report: Just-in-Time Visual Supports to Children with Autism via the Apple Watch:® A Pilot Feasibility Study

Using augmented input might be an effective means for supplementing spoken language for children with autism who have difficulties following spoken directives. This study aimed to (a) explore whether JIT-delivered scene cues (photos, video clips) via the Apple Watch® enable children with autism to carry out directives they were unable to implement with speech alone, and (b) test the feasibility of the Apple Watch® (with a focus on display size). Results indicated that the hierarchical JIT supports enabled five children with autism to carry out the majority of directives. Hence, the relatively small display size of the Apple Watch does not seem to hinder children with autism to glean critical information from visual supports

Evidence Collection for the Unconscious and Unconsented Patient

Forensic nurses are faced with making an ethical decision when an unconscious patient presents with signs of sexual assault. If the patient is unable to consent, the nurses need to decide whether or not to perform a forensic exam. Hospitals have policies in place regarding consent for emergency care, but not all of them consider the collection of forensic evidence. The window of opportunity for forensic collection may disappear before contacts are made or proper consent is established.\ud Ethical, legal, and policy considerations that complicate this scenario are discussed

Characteristics of Internet Addiction/Pathological Internet Use in U.S. University Students: A Qualitative-Method Investigation

Studies have identified high rates and severe consequences of Internet Addiction/Pathological Internet Use (IA/PIU) in university students. However, most research concerning IA/PIU in U.S. university students has been conducted within a quantitative research paradigm, and frequently fails to contextualize the problem of IA/PIU. To address this gap, we conducted an exploratory qualitative study using the focus group approach and examined 27 U.S. university students who self-identified as intensive Internet users, spent more than 25 hours/week on the Internet for non-school or non-work-related activities and who reported Internet-associated health and/or psychosocial problems. Students completed two IA/PIU measures (Young’s Diagnostic Questionnaire and the Compulsive Internet Use Scale) and participated in focus groups exploring the natural history of their Internet use; preferred online activities; emotional, interpersonal, and situational triggers for intensive Internet use; and health and/or psychosocial consequences of their Internet overuse. Students’ self-reports of Internet overuse problems were consistent with results of standardized measures. Students first accessed the Internet at an average age of 9 (SD = 2.7), and first had a problem with Internet overuse at an average age of 16 (SD = 4.3). Sadness and depression, boredom, and stress were common triggers of intensive Internet use. Social media use was nearly universal and pervasive in participants’ lives. Sleep deprivation, academic under-achievement, failure to exercise and to engage in face-to-face social activities, negative affective states, and decreased ability to concentrate were frequently reported consequences of intensive Internet use/Internet overuse. IA/PIU may be an underappreciated problem among U.S. university students and warrants additional research
