Neurodevelopmental Effects of Early Deprivation in Postinstitutionalized Children

The neurodevelopmental sequelae of early deprivation were examined by testing ( N  =   132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized settings showed neuropsychological deficits on tests of visual memory and attention, as well as visually mediated learning and inhibitory control. Yet, these children performed at developmentally appropriate levels on similar tests where auditory processing was also involved and on tests assessing executive processes such as rule acquisition and planning. These findings suggest that specific aspects of brain-behavioral circuitry may be particularly vulnerable to postnatal experience.     

The Knowledgebase at the Center of the Universe

ABSTRACT

Since its advent more than 15 years ago, the knowledgebase has quietly deposed the catalog as the center of the library management and discovery universe. Knowledgebases provide libraries with an inventory of their e-resources holdings and describe the materials that a library has purchased at a more granular level than the traditional bibliographic record. Knowledgebases power key tools such as link resolvers and unified search platforms, support management needs across the e-resources lifecycle, and more recently have evolved to intersect with areas such as linked open data, community contribution models, and next-generation library management platforms. They have truly become the hub from which our most vital services operate. This report will provide an overview of “The Knowledgebase at the Center of the Universe,” an American Library Association Technology Report assessing the state of knowledgebase technology. Topics covered will include an overview of the current product landscape, an exploration of new directions, and case studies from libraries and vendors using knowledgebases in innovative ways.     

Effect of a global alteration of running technique on kinematics and economy

In this study, we examined the consequences of a global alteration in running technique on running kinematics and running economy in triathletes. Sixteen sub-elite triathletes were pre and post tested for running economy and running kinematics at 215 and 250?m?·?min^?1. The members of the treatment group (n = 8) were exposed to 12 weeks of instruction in the “pose method” of running, while the members of the control group (n = 8) maintained their usual running technique. After the treatment period, the experimental group demonstrated a significant decrease in mean stride length (from 137.25?±?7.63?cm to 129.19?±?7.43?cm; P <?0.05), a post-treatment difference in vertical oscillation compared with the control group (6.92?±?1.00 vs. 8.44?±?1.00?cm; P <?0.05) and a mean increase in submaximal absolute oxygen cost (from 3.28?±?0.36?l?·?min^?1 to 3.53?±?0.43?l?·?min^?1; P <?0.01). The control group exhibited no significant changes in either running kinematics or oxygen cost. The global change in running mechanics associated with 12 weeks of instruction in the pose method resulted in a decrease in stride length, a reduced vertical oscillation in comparison with the control group and a decrease of running economy in triathletes.     

Effect of attending to a ball during a side-cut maneuver on lower extremity biomechanics in male and female athletes

Many sports associated with anterior cruciate ligament (ACL) injury require athletes attend to a ball during participation. We investigated effects of attending to a ball on lower extremity mechanics during a side-cut maneuver and if these effects are consistent for males and females. Sagittal and frontal plane hip and knee kinematics and joint moments were measured during side-cut maneuvers in 19 male and 19 female National Collegiate Athletic Association division III basketball players. Participants also experienced two side-cut conditions that required attention to a ball. Our results did not indicate that the effect of attention varies with gender. However, during side-cut conditions while attending to a ball, internal knee adductor moment was 20% greater (p = 0.03) and peak knee flexion angle was 4° larger (p < 0.01). Females demonstrated 5° less hip flexion (p = 0.046), 12° less knee flexion (p < 0.01), and 4° more knee abduction (p = 0.026) at initial contact during all side-cut conditions than males. Attention to a ball may affect lower extremity mechanics relevant to ACL injury. The validity of laboratory studies of lower extremity mechanics for sports that include attention to a ball may be increased if participants are required to attend to a ball during the task.     

Gifted education policy and advocacy: Perspectives for school psychologists

Education laws and policies serve to guide the way programs and services are implemented in schools. The transition from law or policy to implementation can be fraught with complications that impact the education system across many levels. According to Viennet and Pont (2017), one of the areas that can either hinder or support the transition from policy to practice is “inclusive stakeholder engagement” (p. 3). School psychologists are an important stakeholder in the education system thus they should have familiarity with gifted education policy to ensure students are being served appropriately—both academically and socio-emotionally. This article will introduce school psychologists to (a) federal and state laws impacting gifted students, (b) the role litigation, due process, and research has in shaping policy, and (c) relevant gifted education policy considerations.

Childbirth education for multiple pregnancy: part 2: intrapartum and postpartum considerations

Women with a multiple pregnancy can expect a different labor and birth course than those with a singleton pregnancy. While the postpartum period is similar to that of families with a singleton, it is likely to be more hectic in families with multiple infants. In addition, a multiple pregnancy increases both maternal and neonatal risks; therefore, women with a multiple pregnancy may experience slight differences in care due to these potential risks, including additional monitoring and treatment. This article discusses the intrapartum and postpartum considerations families with a multiple pregnancy/birth may experience. This information is provided so that the childbirth educator can incorporate this content into courses, as appropriate, and assist families with a multiple pregnancy to anticipate a realistic birth and postpartum experience.     

Understanding The Impact of an Apprenticeship-Based Scientific Research Program on High School Students’ Understanding of Scientific Inquiry

The purpose of this study was to understand the impact of an apprenticeship program on high school students’ understanding of the nature of scientific inquiry. Data related to seventeen students’ understanding of science and scientific inquiry were collected through open-ended questionnaires. Findings suggest that although engagement in authentic scientific research helped the participants to develop competency in experimentation methods it had limited impact on participants’ learning of the implicit aspects of scientific inquiry and NOS. Discussion focuses on the importance of making the implicit assumptions of science explicit to the students in such authentic scientific inquiry settings through structured curriculum.

Intimate partner violence and child maltreatment: understanding intra- and intergenerational connections

OBJECTIVE: The purpose of this study is to assess the extent to which intimate partner violence and different forms of child maltreatment occur within and across childhood and adulthood for a high-risk group of women. METHOD: Low-income adult women were interviewed, retrospectively, regarding their experiences with intimate partner violence and child maltreatment in childhood and adulthood, and intra- and intergenerational relationships between multiple forms of family violence were identified. RESULTS: Analyses demonstrated weak to moderate associations between various forms of violence within generations. Only weak support was found for the transmission of violence hypothesis that maltreated children are more likely to grow up to maltreat their own children. Stronger support was found for the theory of learned helplessness, whereby children maltreated or witness to violence during childhood are more likely to be victimized as an adult. CONCLUSION: The results from this study suggest that interventions with children who are identified for one form of victimization should be assessed for other forms of victimization, and interventions should also address learned behaviors or beliefs associated with continued or future victimization.
