Predictors of Behavioral Competence and Self-Esteem: A Study Assessing Impact in a Basic Public Speaking Course

As evaluation in higher education receives increasing attention, the assessment of the impact of basic oral communication instruction is becoming more important. This study examines the impact of a public speaking course on undergraduates\u27 affective and behavioral competence. Using a pre- and posttest model, assessment was based on administration of the Communication Competency Assessment Instrument and the Rosenberg Self-Esteem Scale at the beginning and end of the course. Communication competence and self-esteem were measured as a function of communication apprehension, gender, age, and ethnicity. Results indicated that the course generally impacted similarly on students regardless of their level of communication apprehension, gender, age or ethnicity

Predictors of Self-Perceptions of Behavioral Competence, Self-Esteem, and Willingness to Communicate: A Study Assessing Impact in a Basic Interpersonal Communication Course

Considering the emergent role of evaluation in higher education, it is important that assessment procedures be developed for all communication courses. Courses such as public speaking already have well established assessment programs while other courses are in need of additional attention. This article describes an assessment program that examines the impact of an interpersonal course on undergraduates\u27 self-perceived behavioral and affective competence. Using a pre- and post-test model, assessment was based on administration of the Communication Behaviors Inventory, the Rosenberg Self-Esteem Scale, and the Willingness to Communicate Scale. These outcomes were measured as a function of gender, age, and ethnicity. Results indicated that the course impacted similarly on students regardless of these predictor variables, with significant improvement being demonstrated for all groups of students. The article provides a description of the interpersonal course and its assessment procedures. The results of analyses of data are presented with a discussion of future directions for assessment in this course

Why Communication is Important: A Rationale for the Centrality of the Study of Communication

This article defends the importance of studying communication. Academic disciplines in higher education are routinely called upon to explain and justify their role in the educational enterprise. Some academic fields such as history and philosophy are more central in the pursuits of liberal arts, while others such as business administration and engineering are more related to career development. The discipline of communication is fairly unique as it crosses these boundaries. As a result, a need exists to provide a rationale for the study of communication. The National Communication Association, in response to requests from communication departments and administrators for evidence supporting the centrality of their discipline, has collected and annotated nearly 100 articles, commentaries, and publications which call attention to the importance of the study of communication in contemporary society. Four of five major themes in the bibliography provide support for the importance of communication education to: the development of the whole person; the improvement of the educational enterprise; being a responsible citizen of the world, both socially and culturally; and, succeeding in one\u27s career and in the business enterprise. A fifth theme highlights the need for communication education to be provided by those who are specialists in its study

The Basic Communication Course at U.S. Colleges and Universities: VI

This is the sixth in a series of investigations of the basic communication course, begun in 1968 by members of the Undergraduate Speech Instruction Interest Group of the Speech Association of America. This study was replicated in 1974, 1980, 1985, and 1990. Each of these studies gathered and reported information on instructional practices and administrative issues in the basic course at two- and four-year colleges and universities. In this study, the survey instrument from 1990 was revised to reflect contemporary concerns and mailed to the National Communication Association mailing list of 1500 schools. Data were analyzed and presented from 292 responding schools covering institutional demographics and (1) general approach and orientation to the basic course, (2) pedagogy (which subsumes seven sub-categories), (3) enrollment description and dynamics, and (4) administrative concerns. Comparisons to past and studies indicate the basic communication course is thriving and growing, but some of the same problems continue today that beset the course in the past

A New Heavy Flavor Program for the Future Electron-Ion Collider

The proposed high-energy and high-luminosity Electron-Ion Collider (EIC) will provide one of the cleanest environments to precisely determine the nuclear parton distribution functions (nPDFs) in a wide $x$-$Q^{2}$ range. Heavy flavor production at the EIC provides access to nPDFs in the poorly constrained high Bjorken-$x$ region, allows us to study the quark and gluon fragmentation processes, and constrains parton energy loss in cold nuclear matter. Scientists at the Los Alamos National Laboratory are developing a new physics program to study heavy flavor production, flavor tagged jets, and heavy flavor hadron-jet correlations in the nucleon/nucleus going direction at the future EIC. The proposed measurements will provide a unique way to explore the flavor dependent fragmentation functions and energy loss in a heavy nucleus. They will constrain the initial-state effects that are critical for the interpretation of previous and ongoing heavy ion measurements at the Relativistic Heavy Ion Collider and the Large Hadron Collider. We show an initial conceptual design of the proposed Forward Silicon Tracking (FST) detector at the EIC, which is essential to carry out the heavy flavor measurements. We further present initial feasibility studies/simulations of heavy flavor hadron reconstruction using the proposed FST.Comment: 6 pages, 5 figures, proceedings for the XLIX International Symposium on Multiparticle Dynamics (ISMD2019) (9-13 September 2019) conferenc

Thyroid-Hormone–Disrupting Chemicals: Evidence for Dose-Dependent Additivity or Synergism

Endocrine disruption from environmental contaminants has been linked to a broad spectrum of adverse outcomes. One concern about endocrine-disrupting xenobiotics is the potential for additive or synergistic (i.e., greater-than-additive) effects of mixtures. A short-term dosing model to examine the effects of environmental mixtures on thyroid homeostasis has been developed. Prototypic thyroid-disrupting chemicals (TDCs) such as dioxins, polychlorinated biphenyls (PCBs), and poly-brominated diphenyl ethers have been shown to alter thyroid hormone homeostasis in this model primarily by up-regulating hepatic catabolism of thyroid hormones via at least two mechanisms. Our present effort tested the hypothesis that a mixture of TDCs will affect serum total thyroxine (T(4)) concentrations in a dose-additive manner. Young female Long-Evans rats were dosed via gavage with 18 different polyyhalogenated aromatic hydrocarbons [2 dioxins, 4 dibenzofurans, and 12 PCBs, including dioxin-like and non-dioxin-like PCBs] for 4 consecutive days. Serum total T(4) was measured via radioimmunoassay in samples collected 24 hr after the last dose. Extensive dose–response functions (based on seven to nine doses per chemical) were determined for individual chemicals. A mixture was custom synthesized with the ratio of chemicals based on environmental concentrations. Serial dilutions of this mixture ranged from approximately background levels to 100-fold greater than background human daily intakes. Six serial dilutions of the mixture were tested in the same 4-day assay. Doses of individual chemicals that were associated with a 30% TH decrease from control (ED(30)), as well as predicted mixture outcomes were calculated using a flexible single-chemical-required method applicable to chemicals with differing dose thresholds and maximum-effect asymptotes. The single-chemical data were modeled without and with the mixture data to determine, respectively, the expected mixture response (the additivity model) and the experimentally observed mixture response (the empirical model). A likelihood-ratio test revealed statistically significant departure from dose additivity. There was no deviation from additivity at the lowest doses of the mixture, but there was a greater-than-additive effect at the three highest mixtures doses. At high doses the additivity model underpredicted the empirical effects by 2- to 3-fold. These are the first results to suggest dose-dependent additivity and synergism in TDCs that may act via different mechanisms in a complex mixture. The results imply that cumulative risk approaches be considered when assessing the risk of exposure to chemical mixtures that contain TDCs

Development of membranes for hydrogen separation: Pd-coated V-10Pd

Numerous Group IVB and VB alloys were prepared and tested as potential membrane materials but most of these materials were brittle or exhibited cracking during hydrogen exposure. One of the more ductile alloys, V-10Pd (at. %), was fabricated into a thin (107-{micro}m thick) composite membrane coated with 100 nm of Pd on each side. The material was tested for hydrogen permeability, resistance to hydrogen embrittlement, and long term hydrogen flux stability. The hydrogen permeability, {phi}, of the V-10Pd membrane was 3.86 x 10{sup -8} mol H{sub 2} m{sup -1} s{sup -1} Pa{sup -0.5} (avg. of three different samples) at 400 C, which is slightly higher than the permeability of Pd-23Ag at that temperature. A 1400 h hydrogen flux test at 400 C demonstrated that the rate of metallic interdiffusion was slow between the V-10Pd foil and the 100-nm-thick Pd coating on the surface. However, at the end of testing the membrane cracked at 118 C because of hydrogen embrittlement

Downregulation of IRF8 in Alveolar Macrophages by G-CSF Promotes Metastatic Tumor Progression

Tissue-resident macrophages (TRMs) are abundant immune cells within pre-metastatic sites, yet their functional contributions to metastasis remain incompletely understood. Here, we show that alveolar macrophages (AMs), the main TRMs of the lung, are susceptible to downregulation of the immune stimulatory transcription factor IRF8, impairing anti-metastatic activity in models of metastatic breast cancer. G-CSF is a key tumor-associated factor (TAF) that acts upon AMs to reduce IRF8 levels and facilitate metastasis. Translational relevance of IRF8 downregulation was observed among macrophage precursors in breast cancer and

Perceptions of clinical pharmacy specialists' contributions in mental health clinical teams

Introduction: Mental health (MH) clinical pharmacy specialists (CPS) are increasingly functioning as integral providers in MH care teams. MH providers may delegate many medication management tasks to the CPS. As there is a shortage of primary care and specialist MH providers, CPS are increasingly being utilized in MH care clinics. We assess provider and CPS perceptions of the contributions of CPS to MH clinical teams in the Veterans Health Administration. Methods: We examined the roles and functions of CPS in MH clinics through surveys (n=374) and semistructured interviews (n=16) with MH CPS and other members of MH clinical teams (psychiatrists, nurse practitioners, registered nurses, social workers) to gain insight into how CPS were integrated in these settings. We assessed perceptions of CPS contributions to MH teams, interactions between CPS and other providers, and challenges of integrating CPS into MH clinical teams. Results: Contributions of CPS in MH were received positively by clinical team members. Clinical pharmacy specialists providing comprehensive medication management were especially valuable in the management of clozapine. The knowledge and training of CPS reassured providers who frequently referred to them with questions about medication and medication therapy management. MH CPS were also perceived to be received well by patients. Discussion: The integration of MH CPS into MH teams was well received by team members and patients alike. The MH CPS have become important members of the MH team and are widely viewed as being able to improve access, quality, and workflow

National Network of Depression Centers\u27 Recommendations on Harmonizing Clinical Documentation of Electroconvulsive Therapy

Electroconvulsive therapy (ECT) is a highly therapeutic and cost-effective treatment for severe and/or treatment-resistant major depression. However, because of the varied clinical practices, there is a great deal of heterogeneity in how ECT is delivered and documented. This represents both an opportunity to study how differences in implementation influence clinical outcomes and a challenge for carrying out coordinated quality improvement and research efforts across multiple ECT centers. The National Network of Depression Centers, a consortium of 26+ US academic medical centers of excellence providing care for patients with mood disorders, formed a task group with the goals of promoting best clinical practices for the delivery of ECT and to facilitate large-scale, multisite quality improvement and research to advance more effective and safe use of this treatment modality. The National Network of Depression Centers Task Group on ECT set out to define best practices for harmonizing the clinical documentation of ECT across treatment centers to promote clinical interoperability and facilitate a nationwide collaboration that would enable multisite quality improvement and longitudinal research in real-world settings. This article reports on the work of this effort. It focuses on the use of ECT for major depressive disorder, which accounts for the majority of ECT referrals in most countries. However, most of the recommendations on clinical documentation proposed herein will be applicable to the use of ECT for any of its indications
