The Impact of Second Step Implementation on Students’ Social-Emotional Skills in an Elementary School Setting

A positive classroom and a positive school environment are needed to best support students, especially those students with major behavioral concerns. The implementation of the Second Step curriculum is one way to support positive student behavior. This study examined the impact of Second Step implementation methods on students’ emotion management skills. Peer-to-peer, small-group teacher intervention, and whole-group implementation groups in kindergarten and fifth-grade classrooms were studied. Data collection methods included observational checklists, a district created formative assessment, and pre- and post-tests created by the Second Step curriculum. The data collected indicated that many students had an accurate understanding of social-emotional learning skills, but they did not implement emotion-management skills consistently. However, students participating in peer-to-peer emotion management teaching were more self-aware and applied emotion management skills more frequently when compared to students receiving small-group and whole-group instruction. Based on these results, peer-to-peer instruction methods are recommended to strengthen Second Step emotion management skill instruction and student self-awareness

Yeast phosphatidylinositol 4-kinase, Pik1, has essential roles at the Golgi and in the nucleus

Phosphatidylinositol 4-kinase, Pik1, is essential for viability. GFP-Pik1 localized to cytoplasmic puncta and the nucleus. The puncta colocalized with Sec7-DsRed, a marker of trans-Golgi cisternae. Kap95 (importin-β) was necessary for nuclear entry, but not Kap60 (importin-α), and exportin Msn5 was required for nuclear exit. Frq1 (frequenin orthologue) also is essential for viability and binds near the NH(2) terminus of Pik1. Frq1-GFP localized to Golgi puncta, and Pik1 lacking its Frq1-binding site (or Pik1 overexpressed in frq1Δ cells) did not decorate the Golgi, but nuclear localization was unperturbed. Pik1(Δ10-192), which lacks its nuclear export sequence, displayed prominent nuclear accumulation and did not rescue inviability of pik1Δ cells. A Pik1-CCAAX chimera was excluded from the nucleus and also did not rescue inviability of pik1Δ cells. However, coexpression of Pik1(Δ10-192) and Pik1-CCAAX in pik1Δ cells restored viability. Catalytically inactive derivatives of these compartment-restricted Pik1 constructs indicated that PtdIns4P must be generated both in the nucleus and at the Golgi for normal cell function

U.S. official forecasts of Group of Seven economic performance, 1976-90

In this paper, we evaluate the accuracy of the U.S. Treasury Department forecasts of real growth and inflation from 1976 to 1990 for the Group of Seven (G-7) economies. The accuracy of these forecasts is measured against the standard of actual real world growth and inflation as subsequently published in the Treasury's World Economic Outlook (WEO). The primary comparison is to forecasts made by the OECD for each of the G-7 nations, but for the United States and Canada, we compare the forecasts to those made by the Blue Chip consensus and the Federal Reserve 'Greenbook'.Group of Seven countries ; Inflation (Finance)

Assessing a forestry education: The Northern Arizona University experience

In an attempt to provide students with a strong generalist education, the faculty at Northern Arizona University\u27s School of Forestry has presented its undergraduate forestry education in a unique, integrated, team-taught approach for over 20 years. Over this same period of time, higher education has experienced profound changes. Within the discipline, the technical knowledge expected of undergraduates has expanded greatly. Simultaneously the demand for accountability in higher education has increased. Students, parents, state legislators, governing boards, and taxpayers alike have questioned the importance, relevance, and value of higher education. The so-called student-as-consumer model in higher education is but one manifestation of this increased demand for accountability. A fundamental question arises: How well does the forestry program at NAU prepare students educationally as foresters? Assessing student academic achievement with respect to educational outcomes provides one way of answering this question. Such a process can help determine how well students master a set of defined skills, knowledges, and competencies. Such an approach requires a defined set of desired educational outcomes

Естественная радиоактивность кольчугинской серии отложений Ленинского геолого-экономического района Кузбасса

Рассматриваются на основании исследования 1435 образцов горных пород естественные радиоактивные свойства мелко- и крупнозернистого алевролитов и мелкозернистого песчаника, а также каменных углей. Отмечается различие по естественной радиоактивности между основными литологическими разностями пород, слагающих кольчугинскую серию. Естественная радиоактивность пород закономерно уменьшается от алевролитов к песчаникам и к углям. Угли по естественной радиоактивности резко отличаются от вмещающих пород

Neural Plasticity in Moderate to Severe Chronic Stroke Following a Device-Assisted Task-Specific Arm/Hand Intervention

Currently, hand rehabilitation following stroke tends to focus on mildly impaired individuals, partially due to the inability for severely impaired subjects to sufficiently use the paretic hand. Device-assisted interventions offer a means to include this more severe population and show promising behavioral results. However, the ability for this population to demonstrate neural plasticity, a crucial factor in functional recovery following effective post-stroke interventions, remains unclear. This study aimed to investigate neural changes related to hand function induced by a device-assisted task-specific intervention in individuals with moderate to severe chronic stroke (upper extremity Fugl-Meyer < 30). We examined functional cortical reorganization related to paretic hand opening and gray matter (GM) structural changes using a multimodal imaging approach. Individuals demonstrated a shift in cortical activity related to hand opening from the contralesional to the ipsilesional hemisphere following the intervention. This was driven by decreased activity in contralesional primary sensorimotor cortex and increased activity in ipsilesional secondary motor cortex. Additionally, subjects displayed increased GM density in ipsilesional primary sensorimotor cortex and decreased GM density in contralesional primary sensorimotor cortex. These findings suggest that despite moderate to severe chronic impairments, post-stroke participants maintain ability to show cortical reorganization and GM structural changes following a device-assisted task-specific arm/hand intervention. These changes are similar as those reported in post-stroke individuals with mild impairment, suggesting that residual neural plasticity in more severely impaired individuals may have the potential to support improved hand function

METHOTREXATE ACTION IN RHEUMATOID ARTHRITIS: STIMULATION OF CYTOKINE INHIBITOR AND INHIBITION OF CHEMOKINE PRODUCTION BY PERIPHERAL BLOOD MONONUCLEAR CELLS

This open label study examines whether methotrexate (MTX) treatment modulates ex vivo synthesis of interleukin-1 receptor antagonist (IL-lra), soluble tumour necrosis factor receptors(sTNFR p55 and p75), interleukin-1β (IL-1β), tumour necrosis factor α(TNF-α), interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) by peripheral blood mononuclear cells (PBMC} and whether changes reflect clinical response. Significant stimulation of IL-lra and sTNFR p75 as well as inhibition of IL-8 production of PBMC were associated with clinical improvement observed in patients treated with MTX. When defining the characteristics of patients at study entry retrospectively in responders and non-responders a significantly lower ratio of IL-lra :IL-1β production before and its increase upon treatment was associated with clinical response in 13 patients compared to five patients not responding to MTX. In addition, clinical improvement was associated with decreased synthesis of IL-1β, TNF-α and IL-8 induced by bacterial lipopolysaccharide, IL-1α and IL-1β in PBMC in vitro. These findings suggest that MTX therapy reverses the inflammatory type of rheumatoid arthritis (RA) blood mononuclear cells by stimulating cytokine inhibitor production while inhibiting inflammatory cytokine release at the same time. This may explain the powerful anti-inflammatory properties of low-dose MTX as observed in most RA patients. Pretreatment determination of the IL-lra: IL-1β ratio in PBMC may be predictive with regard to a favourable therapeutic response and therefore may be useful for the selection of RA patients to be treated with MT

Improving Hand Function of Severely Impaired Chronic Hemiparetic Stroke Individuals Using Task-Specific Training With the ReIn-Hand System: A Case Series

Purpose: In this study, we explored whether improved hand function is possible in poststroke chronic hemiparetic individuals with severe upper limb motor impairments when they participate in device-aided task-specific practice.Subjects: Eight participants suffering from chronic stroke (>1-year poststroke, mean: 11.2 years) with severely impaired upper extremity movement (Upper Extremity Subscale of the Fugl-Meyer Motor Assessment (UEFMA) score between 10 and 24) participated in this study.Methods: Subjects were recruited to participate in a 20-session intervention (3 sessions/7 weeks). During each session, participants performed 20–30 trials of reaching, grasping, retrieving, and releasing a jar with the assistance of a novel electromyography-driven functional electrical stimulation (EMG-FES) system.This EMG-FES system allows for Reliable and Intuitive use of the Hand (called ReIn-Hand device) during multi-joint arm movements. Pre-, post-, and 3-month follow-up outcome assessments included the UEFMA, Cherokee McMaster Stroke Assessment, grip dynamometry, Box and Blocks Test (BBT), goniometric assessment of active and passive ranges of motion (ROMs) of the wrist and the metacarpophalangeal flexion and extension (II, V fingers), Nottingham Sensory Assessment–Stereognosis portion (NSA), and Cutaneous Sensory Touch Threshold Assessment.Results: A nonparametric Friedman test of differences found significant changes in the BBT scores (χ2 = 10.38, p < 0.05), the passive and active ROMs (χ2 = 11.31, p < 0.05 and χ2 = 12.45, p < 0.01, respectively), and the NSA scores (χ2 = 6.42, p < 0.05) following a multi-session intervention using the ReIn-Hand device.Conclusions: These results suggest that using the ReIn-Hand device during reaching and grasping activities may contribute to improvements in gross motor function and sensation (stereognosis) in individuals with chronic severe UE motor impairment following stroke

Surface and Sub-Surface Composition and Properties of Ion-Bombarded Lithium Alloys

Lithium-bearing alloys such as Si-Li, Al-Li and Cu-Li are of importance in a variety of technological applications, many of them depending on the fact that the surface composition of these alloys differs significantly from that of the bulk, both at thermal equilibrium and under ion bombardment. During ion sputtering, these materials exhibit a variety of phenomena which affect the surface composition and concentration depth profile in a complex manner. We present here experimental measurements of the surface and near-surface composition profiles of sputtered Cu-Li and Al-Li alloys. The experimental results are interpreted in terms of surface loss and radiation-induced segregation processes. Emphasis is placed on the use of these materials for use as plasma-interactive components in magnetic-confinement fusion applications
