Basic Counseling Techniques Training: The Differential Effects of Two Models on Skill Development and Fully Functioning

The purpose of this study is to examine the effects of two models of basic counseling skill training on the development of fully functioning, and the frequency of basic skill utilization as assessed at the end of the course. Two groups of students were taught using the Carkhuff Human Resource Development model (1971) and Egan’s Skilled Helper model (2002). They were then given the Strathclyde inventory to assess fully functioning early and at the end of the semester, and skill frequency count was conducted on all participants. Mann-Whitney-Wilcoxon tests were conducted to determine difference between groups in both measures. Additionally, inter-rater reliability was established on the skill frequency count. Analysis demonstrated that change occurred over the course of the semester for both groups in terms of fully functioning, with the group based on Carkhuff’s Human Resource Development showing more change. Analysis also demonstrated a larger frequency of empathic responses with the group taught from the Carkhuff model

High-Frequency Electron-Spin-Resonance Study of the Octanuclear Ferric Wheel CsFe8_8

High-frequency ($f$ = 190 GHz) electron paramagnetic resonance (EPR) at magnetic fields up to 12 T as well as Q-band ($f$ = 34.1 GHz) EPR were performed on single crystals of the molecular wheel CsFe$_8$. In this molecule, eight Fe(III) ions, which are coupled by nearest-neighbor antiferromagnetic (AF) Heisenberg exchange interactions, form a nearly perfect ring. The angle-dependent EPR data allow for the accurate determination of the spin Hamiltonian parameters of the lowest spin multiplets with $S \leq$ 4. Furthermore, the data can well be reproduced by a dimer model with a uniaxial anisotropy term, with only two free parameters $J$ and $D$. A fit to the dimer model yields $J$ = -15(2) cm$^{-1}$ and $D$ = -0.3940(8) cm$^{-1}$. A rhombic anisotropy term is found to be negligibly small, $E$ = 0.000(2) cm$^{-1}$. The results are in excellent agreement with previous inelastic neutron scattering (INS) and high-field torque measurements. They confirm that the CsFe$_8$ molecule is an excellent experimental model of an AF Heisenberg ring. These findings are also important within the scope of further investigations on this molecule such as the exploration of recently observed magnetoelastic instabilities.Comment: 21 pages, 8 figures, accepted for publication in Inorganic Chemistr

Comparison And Validation Of Modelling Methods For Non-Homogenous Walls Incorporating Vacuum Insulation Panels

As of 2012, space heating accounted for 62% of Canada’s secondary residential energy use, the most significant category by a large margin. New strategies and policies to reduce overall energy consumption, with a focus on reducing space heating energy. Voluntary performances standards have been developed for new homes including R-2000, LEED Canada for Homes and Passive House. These standards add a series of performance criteria, in addition to conventional building code, in an effort to reduce a home’s energy consumption and include a limit on energy and water consumption, and prescribe minimum levels of insulation, ventilation, etc. Generally, extensive modelling, proof of concept and/or builder training are required to obtain the energy efficiency designation. A common method of maintaining a home within the constrained energy budget is to increase the overall air tightness and insulation in the dwelling above conventional construction standards through additional sealing and insulation. The typical industry practice for increasing the insulation value involves simply adding more insulation. However, this practice is not always possible or favorable. For example, adding thickness to the walls will either increase the dwelling’s footprint or reduce the usefulfloor space within the home. As a consequence, many studies are being performed on vacuum insulated panels (VIPs), which offer a high thermal resistance per unit thickness when compared to conventional materials. VIPs consist of a metallic enclosure and a vacuum maintained inside, effectively eliminating the conduction through the center of panel, however a thermal bridge will occur along the edges. There are concerns about whether the fragility and the non-homogenous nature of the panels will cause problems within residential dwellings, as well as how to model VIPs within building assemblies effectively. Currently, there is no method of efficiently modelling the non-homogenous nature of the panels in building applications to meet requirements prescribed in performance standards, hinders the widespread adoption of VIPs. This paper compares two methods of modelling the steady-state heat transfer across a composite, non-homogenous wall assembly containing VIPs validated against measured experimental data. Method 1 is the typical practice used by industry experts and involves creating a thermal model for each unique 2D profile within the wall assembly independently. The effective thermal conductivity (U-value) for the assembly was calculated using weighted averages method based on proportional coverage area of each profile and involves multiplying the U-value by the ratio of profile height to the overall height of the wall. In method 2, a single profile was created based on the wall composition, coverage area, and layout of non-homogenous sections to represent the entire assembly then modelled in THERM. The results of both methods were compared to an empirically calculated thermal resistance based on measured heat flux across five points in a representative assembly under steady-state conditions in a guarded hot box. The feasibility of using either modelling method to find the thermal resistance of wall assemblies incorporating VIPs and if a single representative profile can accurately determine thermal resistance to avoid modelling all profiles included within the wall was examined

"The dirty hand in the latex glove": a study of hand hygiene compliance when gloves are worn.

Wearing of gloves reduces transmission of organisms by healthcare workers' hands but is not a substitute for hand hygiene. Results of previous studies have varied as to whether hand hygiene is worse when gloves are worn. Most studies have been small and used nonstandardized assessments of glove use and hand hygiene. We sought to observe whether gloves were worn when appropriate and whether hand hygiene compliance differed when gloves were worn

The Amyloid Fibril-Forming β-Sheet Regions of Amyloid β and α-Synuclein Preferentially Interact with the Molecular Chaperone 14-3-3ζ.

14-3-3 proteins are abundant, intramolecular proteins that play a pivotal role in cellular signal transduction by interacting with phosphorylated ligands. In addition, they are molecular chaperones that prevent protein unfolding and aggregation under cellular stress conditions in a similar manner to the unrelated small heat-shock proteins. In vivo, amyloid β (Aβ) and α-synuclein (α-syn) form amyloid fibrils in Alzheimer's and Parkinson's diseases, respectively, a process that is intimately linked to the diseases' progression. The 14-3-3ζ isoform potently inhibited in vitro fibril formation of the 40-amino acid form of Aβ (Aβ40) but had little effect on α-syn aggregation. Solution-phase NMR spectroscopy of 15N-labeled Aβ40 and A53T α-syn determined that unlabeled 14-3-3ζ interacted preferentially with hydrophobic regions of Aβ40 (L11-H21 and G29-V40) and α-syn (V3-K10 and V40-K60). In both proteins, these regions adopt β-strands within the core of the amyloid fibrils prepared in vitro as well as those isolated from the inclusions of diseased individuals. The interaction with 14-3-3ζ is transient and occurs at the early stages of the fibrillar aggregation pathway to maintain the native, monomeric, and unfolded structure of Aβ40 and α-syn. The N-terminal regions of α-syn interacting with 14-3-3ζ correspond with those that interact with other molecular chaperones as monitored by in-cell NMR spectroscopy

An integrative study of motivation and goal regulation processes in subclinical anxiety, depression and hypomania

Research has implicated motivation and goal regulation in susceptibility to mood disorders. We studied for the first time key facets of motivation and goal regulation concurrently in relation to affective symptoms. The cross-national sample comprised 510 university students from the United States (n = 279) and United Kingdom (n = 231). Participants completed self-report measures of motivation, conditional goal setting, urgency, depression, anxiety, and mania risk. Structural Equation Modeling results found that behavioral activation system scores correlated negatively with depression and positively with mania risk, but were unrelated to anxiety. High conditional goal setting correlated uniquely with higher depression but not to anxiety or mania risk. Urgency correlated with higher anxiety, depression, and mania risk. Behavioral inhibition system scores correlated negatively with mania risk but unexpectedly did not correlate with anxiety in the multivariate model. The behavioral activation, behavioral inhibition, conditional goal setting, and urgency results showed shared and distinct patterns of relationships with depression, anxiety and mania risk. Our findings indicate unique and common risk vulnerabilities in depressive, anxious, and manic syndromes and extend an integrative knowledge of these syndromes in relation to goal regulation
