Exploring Living-Learning Communities as a Venue for Men’s Identity Construction.

THIS QUALITATIVE STUDY EXPLORED how male undergraduate students experienced living-learning community environments. Findings revealed that living-learning communities provided men a safe haven from rigid gender role expectations, offered a plethora of involvement opportunities, and fostered relationships with faculty and peers. The findings highlight the potential of living-learning communities to provide men with the support they need to reject rigid gender expectations and develop a healthy identity. Recommendations for practice are discussed

The Role of Social Justice Living-Learning Communities in Promoting Students Understanding of Social Justice and LLC Involvement

In this qualitative, multiple-case study, we explored 30 students\u27 experiences across three social justice living-learning communities (LLC) to understand their conception of social justice and LLC involvement. Moreover, we examined the community elements that advanced these outcomes. Despite similar goals across communities, students demonstrated variation in their understanding of and commitment to involvement in social justice initiatives. We advance a typology describing patterns of involvement and social justice understanding in which we categorize students into four quadrants, including informed activist, informed bystander, uninformed volunteer, and uninformed bystander. Further, we describe contextual elements that influenced these patterns, discussing implications for practice

Metalinguistic Language Development and Literacy Success in First Grade Children with Language Impairment

Purpose. This study explores how the development of meaning (morphology), spelling patterns (orthography), and sound patterns (phonology) are related to literacy success in young elementary school children with and without language impairment. Significance. Young school-age children with language impairment (LI) are at risk for experiencing a literacy deficit (Catts, Adlof, Hogan & Weismer, 2005). The basic foundational skills required to read and write language are also those required to understand and produce spoken language. Phonological awareness is one language skill that is highly predictive of literacy success (Catts, Fey, Zhang, & Tomblin, 2001), however, it is not the only skill that affects reading and writing development. Recently, the language abilities of orthographic knowledge and morphological awareness were found related to literacy success in children with and without LI (e.g., Wolter & Apel, 2010; Wolter, Wood, & D’zatko, 2009). Orthographic knowledge refers to the ability to actively, store, and access complete letter patterns/representations of written words in memory. Morphological awareness can be defined as the conscious awareness of the meaningful units of words (e.g., base word / suffix). Thus, this research sought to determine whether these skills uniquely influence reading and spelling abilities in elementary children with and without LI and whether differences exist between these groups of children. Methodology. Children in kindergarten and 1st-grade with and without LI completed measures of phonological, morphological, and orthographic awareness as well as a battery of reading and writing tests. Statistical analyses revealed the children with LI performed significantly different than those with typical language on orthographic knowledge or morphological awareness measures. In addition, phonological awareness, orthographic knowledge, and morphological awareness appeared to be related to reading and spelling in both groups of children. Future research and clinical implications will be discussed

Characterization of Soil Water Content Variability and Soil Texture Using GPR Groundwave Techniques

Accurate characterization of near-surface soil water content is vital for guiding agricultural management decisions and for reducing the potential negative environmental impacts of agriculture. Characterizing the near-surface soil water content can be difficult, as this parameter is often both spatially and temporally variable, and obtaining sufficient measurements to describe the heterogeneity can be prohibitively expensive. Understanding the spatial correlation of near-surface soil water content can help optimize data acquisition and improve understanding of the processes controlling soil water content at the field scale. In this study, ground penetrating radar (GPR) methods were used to characterize the spatial correlation of water content in a three acre field as a function of sampling depth, season, vegetation, and soil texture. GPR data were acquired with 450 MHz and 900 MHz antennas, and measurements of the GPR groundwave were used to estimate soil water content at four different times. Additional water content estimates were obtained using time domain reflectometry measurements, and soil texture measurements were also acquired. Variograms were calculated for each set of measurements, and comparison of these variograms showed that the horizontal spatial correlation was greater for deeper water content measurements than for shallower measurements. Precipitation and irrigation were both shown to increase the spatial variability of water content, while shallowly-rooted vegetation decreased the variability. Comparison of the variograms of water content and soil texture showed that soil texture generally had greater small-scale spatial correlation than water content, and that the variability of water content in deeper soil layers was more closely correlated to soil texture than were shallower water content measurements. Lastly, cross-variograms of soil texture and water content were calculated, and co-kriging of water content estimates and soil texture measurements showed that geophysically-derived estimates of soil water content could be used to improve spatial estimation of soil texture

Sodium intercalation into α- and β-VOSO4

Received: 12.02.2019. Accepted: 19.03.2019. Published: 29.03.2019.Na-ion battery is one of the best alternatives to Li-ion battery. Abundance of sodium on earth is three orders of magnitude higher than lithium, which should make Na-ion battery technology cheaper. But alkaline-ion battery prices, which tend to increase because of the massive world demand, also depend on the choice of electrode materials. Therefore, cost-effective electrode development remains an important subject of research because this will allow Na-ion battery to be even more competitive. Electrochemical performances of anhydrous VOSO4 as electrode for Na-ion battery are reported in this letter. Two anhydrous phases of vanadyl sulfate have been studied. The first one, α-VOSO4, shows that up to 0.8 sodium per formula unit (Na/f.u.) can be intercalated in this phase, and a reversible intercalation of 0.4 Na/f.u. has been observed with a strong polarization. The second one, β-VOSO4, can intercalate up to 0.9 Na/f.u. with a reversible inter- calation of 0.4 Na/f.u. leading to a reversible capacity of 64 mAh/g
