    Get PDF
    The authors analyzed the narrative writings of four counselors-in-training in practicum using directed content analysis. Developmental themes corresponded to current theories of counselor development. Narratives and supervisor responses are sequentially provided to aid new counselors and supervisors in understanding the complexities of counselor developmental and counselor supervision

    Test Anxiety and Relaxation Training in Third-Grade Students

    As testing becomes an achievement marker for elementary school children, test anxiety would naturally follow for these children. This study looks at test anxiety in third grade students, as well as relaxation training as a treatment modality to deal with that anxiety. One hundred and four third grade students participated in this study. Those students that received relaxation training experienced less test anxiety after the treatment. Students in the control group showed no changes in test anxiety. The use of relaxation training among third grade students may be a beneficial method for teachers to reduce anxiety in their students

    Adaptation of the Child - Parent Relationship Therapy Model for Use With Senior Citizen Volunteers in School Settings: A Pilot Study

    Get PDF
    This study provides a proposal for crucial volunteer services to fill the gap for overburdened school counselors when parents are unable to engage in Child-Parent Relationship Therapy (CPRT), a highly effective intervention for childhood problems. CPRT has been successfully adapted for use with individuals other than the child’s parents. The researcher in this pilot study adapted CPRT for use with senior citizen volunteers who often possess untapped abilities and talents. Seniors received several weeks of training, and then met with children for 1/2 hour supervised, video-taped play sessions for several weeks. Childhood adjustment problems were assessed before and after the intervention using the Child Behavior Checklist (CBCL) and Teacher Report Form (TRF). Seniors’ responses were measured before and after with the Older Adult Self-Report and qualitative interviews. Although no significant differences were noted on pre versus posttest measures for the children (CBCL and TRF), anecdotal reports suggest potential effectiveness of this volunteer intervention for school counselors to utilize. In addition, senior citizens reported their own benefits from working with the children. Suggestions for future research in this area are offered

    Regional to Global Assessments of Phytoplankton Dynamics From The SeaWiFS Mission

    Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary biological property retrieved from SeaWiFS, have traditionally been used as a metric for phytoplankton abundance and its distribution largely reflects patterns in vertical nutrient transport. On regional to global scales, chlorophyll concentrations covary with sea surface temperature (SST) because SST changes reflect light and nutrient conditions. However, the oceanmay be too complex to be well characterized using a single index such as the chlorophyll concentration. A semi-analytical bio-optical algorithm is used to help interpret regional to global SeaWiFS chlorophyll observations from using three independent, well-validated ocean color data products; the chlorophyll a concentration, absorption by CDM and particulate backscattering. First, we show that observed long-term, global-scale trends in standard chlorophyll retrievals are likely compromised by coincident changes in CDM. Second, we partition the chlorophyll signal into a component due to phytoplankton biomass changes and a component caused by physiological adjustments in intracellular chlorophyll concentrations to changes in mixed layer light levels. We show that biomass changes dominate chlorophyll signals for the high latitude seas and where persistent vertical upwelling is known to occur, while physiological processes dominate chlorophyll variability over much of the tropical and subtropical oceans. The SeaWiFS data set demonstrates complexity in the interpretation of changes in regional to global phytoplankton distributions and illustrates limitations for the assessment of phytoplankton dynamics using chlorophyll retrievals alone

    Effects of Relaxation and Deep-Breathing on High School Students: ACT Prep

    Get PDF
    The purpose of this study was to relieve test anxiety in high school juniors preparing to take the ACT: a high-stakes, college admissions, standardized test. Participants included 81 eleventh grade students (25 males, 56 females) from a Midwestern public high school. Results demonstrated that relaxation training in the experimental group significantly lowered student’s perceptions of test anxiety from pre-test to post-test. Further research regarding systematic deep breathing and relaxation techniques is needed

    Pre-Conceptual Design of a Fluoride-Salt-Cooled Small Modular Advanced High Temperature Reactor (SmAHTR)

    Get PDF
    This document presents the results of a study conducted at Oak Ridge National Laboratory during 2010 to explore the feasibility of small modular fluoride salt-cooled high temperature reactors (FHRs). A preliminary reactor system concept, SmATHR (for Small modular Advanced High Temperature Reactor) is described, along with an integrated high-temperature thermal energy storage or salt vault system. The SmAHTR is a 125 MWt, integral primary, liquid salt cooled, coated particle-graphite fueled, low-pressure system operating at 700 C. The system employs passive decay heat removal and two-out-of-three , 50% capacity, subsystem redundancy for critical functions. The reactor vessel is sufficiently small to be transportable on standard commercial tractor-trailer transport vehicles. Initial transient analyses indicated the transition from normal reactor operations to passive decay heat removal is accomplished in a manner that preserves robust safety margins at all times during the transient. Numerous trade studies and trade-space considerations are discussed, along with the resultant initial system concept. The current concept is not optimized. Work remains to more completely define the overall system with particular emphasis on refining the final fuel/core configuration, salt vault configuration, and integrated system dynamics and safety behavior

    The Liganding of Glycolipid Transfer Protein Is Controlled by Glycolipid Acyl Structure

    Get PDF
    Glycosphingolipids (GSLs) play major roles in cellular growth and development. Mammalian glycolipid transfer proteins (GLTPs) are potential regulators of cell processes mediated by GSLs and display a unique architecture among lipid binding/transfer proteins. The GLTP fold represents a novel membrane targeting/interaction domain among peripheral proteins. Here we report crystal structures of human GLTP bound to GSLs of diverse acyl chain length, unsaturation, and sugar composition. Structural comparisons show a highly conserved anchoring of galactosyl- and lactosyl-amide headgroups by the GLTP recognition center. By contrast, acyl chain chemical structure and occupancy of the hydrophobic tunnel dictate partitioning between sphingosine-in and newly-observed sphingosine-out ligand-binding modes. The structural insights, combined with computed interaction propensity distributions, suggest a concerted sequence of events mediated by GLTP conformational changes during GSL transfer to and/or from membranes, as well as during GSL presentation and/or transfer to other proteins
