The Higher Education Option for Poor Women with Children

Postsecondary education is the key to exiting from poverty permanently. Yet, the PRWORA allows women only up to 12 months of vocational training while on welfare. This paper focuses on bringing back the importance of investing in the education of poor women, particularly the postsecondary education of poor women with children, to the forefront of the welfare debate. In this paper we review federal and state level welfare policies toward postsecondary education of poor women with children. Some states are interpreting federal welfare policy strictly and allowing only up to 12 months of vocational training while on welfare. Other states allow poor women attending postsecondary education to count class hours and homework hours toward the work participation requirement. Support services-childcarea nd transportation-tow omen attending college vary from state to state. Services for welfare mothers who wish to go on to college are severely inadequate. We argue that federal and state policies should be designed to encourage poor women to complete two- and fouryear college degrees because education of women is associated with better economic and social returns for women, children, families and society at large. We propose that welfare policies should encourage women\u27s college education by providing support services and by stopping the five-years clock for those attending college. In addition, programs such as Individual Development Accounts (IDAs) and AmeriCorps should be expanded to increase postsecondary education opportunities for poor women

Neural encoding of the speech envelope by children with developmental dyslexia.

Developmental dyslexia is consistently associated with difficulties in processing phonology (linguistic sound structure) across languages. One view is that dyslexia is characterised by a cognitive impairment in the "phonological representation" of word forms, which arises long before the child presents with a reading problem. Here we investigate a possible neural basis for developmental phonological impairments. We assess the neural quality of speech encoding in children with dyslexia by measuring the accuracy of low-frequency speech envelope encoding using EEG. We tested children with dyslexia and chronological age-matched (CA) and reading-level matched (RL) younger children. Participants listened to semantically-unpredictable sentences in a word report task. The sentences were noise-vocoded to increase reliance on envelope cues. Envelope reconstruction for envelopes between 0 and 10Hz showed that the children with dyslexia had significantly poorer speech encoding in the 0-2Hz band compared to both CA and RL controls. These data suggest that impaired neural encoding of low frequency speech envelopes, related to speech prosody, may underpin the phonological deficit that causes dyslexia across languages.Medical Research Council (Grant ID: G0902375)This is the final version of the article.

The Factory and The Beehive I. Rotation Periods For Low-Mass Stars in Praesepe

Stellar rotation periods measured from single-age populations are critical for investigating how stellar angular momentum content evolves over time, how that evolution depends on mass, and how rotation influences the stellar dynamo and the magnetically heated chromosphere and corona. We report rotation periods for 40 late-K to mid-M stars members of the nearby, rich, intermediate-age (~600 Myr) open cluster Praesepe. These rotation periods were derived from ~200 observations taken by the Palomar Transient Factory of four cluster fields from 2010 February to May. Our measurements indicate that Praesepe's mass-period relation transitions from a well-defined singular relation to a more scattered distribution of both fast and slow rotators at ~0.6 Msun. The location of this transition is broadly consistent with expectations based on observations of younger clusters and the assumption that stellar-spin down is the dominant mechanism influencing angular momentum evolution at 600 Myr. However, a comparison to data recently published for the Hyades, assumed to be coeval to Praesepe, indicates that the divergence from a singular mass-period relation occurs at different characteristic masses, strengthening the finding that Praesepe is the younger of the two clusters. We also use previously published relations describing the evolution of rotation periods as a function of color and mass to evolve the sample of Praesepe periods in time. Comparing the resulting predictions to periods measured in M35 and NGC 2516 (~150 Myr) and for kinematically selected young and old field star populations suggests that stellar spin-down may progress more slowly than described by these relations.Comment: To appear in the ApJ. 18 pages, 12 figures; version with higher resolution figures available at http://www.astro.columbia.edu/~marcel/papers/praesepe.pdf.

Perception of Filtered Speech by Children with Developmental Dyslexia and Children with Specific Language Impairments.

Here we use two filtered speech tasks to investigate children's processing of slow (<4 Hz) versus faster (∼33 Hz) temporal modulations in speech. We compare groups of children with either developmental dyslexia (Experiment 1) or speech and language impairments (SLIs, Experiment 2) to groups of typically-developing (TD) children age-matched to each disorder group. Ten nursery rhymes were filtered so that their modulation frequencies were either low-pass filtered (<4 Hz) or band-pass filtered (22 - 40 Hz). Recognition of the filtered nursery rhymes was tested in a picture recognition multiple choice paradigm. Children with dyslexia aged 10 years showed equivalent recognition overall to TD controls for both the low-pass and band-pass filtered stimuli, but showed significantly impaired acoustic learning during the experiment from low-pass filtered targets. Children with oral SLIs aged 9 years showed significantly poorer recognition of band pass filtered targets compared to their TD controls, and showed comparable acoustic learning effects to TD children during the experiment. The SLI samples were also divided into children with and without phonological difficulties. The children with both SLI and phonological difficulties were impaired in recognizing both kinds of filtered speech. These data are suggestive of impaired temporal sampling of the speech signal at different modulation rates by children with different kinds of developmental language disorder. Both SLI and dyslexic samples showed impaired discrimination of amplitude rise times. Implications of these findings for a temporal sampling framework for understanding developmental language disorders are discussed.Medical Research Council (Grant ID: G0400574)This is the final version of the article.

ExpiSf™: A chemically-defined baculovirus-based expression system for enhanced Protein production in Sf9 cells

The Baculovirus Expression Vector System (BEVS) is one of the major platforms for recombinant protein production and the last decade has become a preferred platform for vaccine development. Unlike mammalian expression systems that have long since transitioned to serum-free, chemically-defined culture media, relatively little innovation has taken place in insect expression systems, with insect cells continuing to rely on undefined, yeastolate-containing culture media that can exhibit significant lot-to-lot variability in terms of both cell growth and protein expression. Here, we present the development of a novel Sf9-based Baculovirus expression system based on a high-density, chemically-defined culture medium, a high-expressing Sf9 cell line, improved transfection reagent to faster generation of baculoviruses and expression enhancer that allow for consistent production of recombinant proteins with two-fold or greater improvements in protein titers compared to traditional BEVS workflows

Navigating Social and Emotional Learning from the Inside Out: ?????????????????????Looking Inside and Across 33 leading SEL Programs: A Practical Resource for Schools and OST Providers

The field of social and emotional learning (SEL) is rapidly expanding, as educators bring a sharper focus to helping children build skills beyond academic knowledge. School climate initiatives, anti-bullying work, positive behavior supports and other SEL efforts are now steering programs in schools and out-of-school-time (OST) settings across the country. Building children's SEL skills has taken on even more urgency in the wake of the COVID-19 pandemic.This updated and expanded guide to evidence-based SEL programs offers detailed information on 33 pre-K through elementary school programs, encompassing curricular content and program highlights. Practitioners from schools, early childhood education (ECE) providers and out-of-school time (OST) can use this resource to look "inside and across" programs to better understand program content and assess program fit with their district or community needs.New chapters in the 2021 edition include recommendations for achieving equitable SEL (including common barriers and best practices) and guidance on trauma-informed or trauma-sensitive approaches to SEL, which includes principles, practices and recommendations for integrating SEL into regular practice

Genome-to-genome analysis highlights the effect of the human innate and adaptive immune systems on the hepatitis C virus

Outcomes of hepatitis C virus (HCV) infection and treatment depend on viral and host genetic factors. Here we use human genome-wide genotyping arrays and new whole-genome HCV viral sequencing technologies to perform a systematic genome-to-genome study of 542 individuals who were chronically infected with HCV, predominantly genotype 3. We show that both alleles of genes encoding human leukocyte antigen molecules and genes encoding components of the interferon lambda innate immune system drive viral polymorphism. Additionally, we show that IFNL4 genotypes determine HCV viral load through a mechanism dependent on a specific amino acid residue in the HCV NS5A protein. These findings highlight the interplay between the innate immune system and the viral genome in HCV control

Atypical genomic cortical patterning in autism with poor early language outcome.

Cortical regionalization develops via genomic patterning along anterior-posterior (A-P) and dorsal-ventral (D-V) gradients. Here, we find that normative A-P and D-V genomic patterning of cortical surface area (SA) and thickness (CT), present in typically developing and autistic toddlers with good early language outcome, is absent in autistic toddlers with poor early language outcome. Autistic toddlers with poor early language outcome are instead specifically characterized by a secondary and independent genomic patterning effect on CT. Genes involved in these effects can be traced back to midgestational A-P and D-V gene expression gradients and different prenatal cell types (e.g., progenitor cells and excitatory neurons), are functionally important for vocal learning and human-specific evolution, and are prominent in prenatal coexpression networks enriched for high-penetrance autism risk genes. Autism with poor early language outcome may be explained by atypical genomic cortical patterning starting in prenatal development, which may detrimentally affect later regional functional specialization and circuit formation

The Effects of Methylphenidate on the Neural Signatures of Sustained Attention

BACKGROUND: Although it is well established that methylphenidate (MPH) enhances sustained attention, the neural mechanisms underpinning this improvement remain unclear. We examined how MPH influenced known electro-physiological precursors of lapsing attention over different time scales
