description: The purpose of this study was to investigate the specific characteristics of literacy training programs of selected utility companies in the metropolitan Washington, D.C., area. The study analyzed these characteristics: curriculum, instruction, program administration, and career development. The case study methodology, using two utility companies, was chosen for data collection. Data were gathered from these sources: (a) structured interviews with students, instructors, program administrators, and company supervisors; (b) classroom observations; and (c) analysis of company and employee records. The significant findings for each of the characteristics studied indicated: (a) curriculum was designed by PLAN, INC., a nonprofit consulting firm, choosing both job-related and general literacy materials; (b) instructional activities were determined by the consultant and emphasized small group teaching based on students' test scores; (c) administrative issues were mainly the responsibility of company officials, but evaluation was managed jointly by company and consultant; and (d) career development was determined by company officials. As a result of the findings, it was concluded that: (1) No single, clear model of literacy development was followed; (2) An eclectic approach to instruction was used; (3) Literacy training provided on the job site, with time shared by the employer, was effective; (4) Participants improved their job-related literacy skills; (5) Literacy training improved general organizational effectiveness and affected employee job mobility; (6) Literacy training improved morale and motivation of participants; (7) Planning and developing literacy training were jointly shared between company and consultant. The findings of the research suggested recommendations for practice and for future research. For the practitioner, it was recommended that (a) professional trade associations establish industry-wide committees to address literacy issues; (b) the human resource staff understand the difference between general training and literacy training; (c) corporate literacy programs focus on specific job-related literacy skills which are reinforced through planned on-the-job experiences; and (d) needs assessments, including a job and task analysis, be conducted to determine the literacy needs of employees.

description: Objectives: The study aims to investigate occupational exposure to carbon fibers impregnated with epoxy resins (carbon fiber reinforced [CFR]) in workers at an airplane fuselage section construction plant, by environmental and biological monitoring. Materials and methods: Determination of airborne CFR was done by environmental sampling with active samplers, 11 of which were stationary and 19 personal samplings. The subsequent analyses were performed in the scanning electron microscope fitted with an X-ray microanalysis system (SEM-EDXA). Biological monitoring was carried out by determining CFR in exhaled breath condensate (EBC) collected from 19 male workers who wore personal environmental samplers (exposed workers) and from 10 male workers at the same factory who had no occupational exposure to CFR (internal controls). CFR analysis was done by SEM, applying the method used for determining asbestos fibers in aqueous samples. Results: The airborne CFR concentrations were found to be significantly higher (p = 0.03) at personal samplings (median value 7.01 ff/L, range 1.24–11.16 ff/L) than stationary samplings (median value 1.93 ff/L, range 0.55–10.09 ff/L). The aerodynamic diameters calculated starting from the length and geometric diameter of the sampled CFRs were always higher than 20 µm. CFR was not found in any of the EBC samples collected from the exposed workers and controls. Conclusions: Despite the evidence of occupational exposure to low concentrations of CFR, the absence of such fibers in the EBC in the exposed workers confirms their non-respirability, as expected based on their aerodynamic diameter.

"WHAT'S A DEVELOPING COUNTRY?": FIELD TRIALS AND REVISIONS OF A DEVELOPMENT EDUCATION PROGRAM FOR ADULT AMERICANS
Creators: name: Swing, Nancy
Publisher: name: American University
Year: 2023

description: The United States and the Third World are interdependent economically, politically, environmentally, culturally, and socially. Yet indications are that U.S. citizens have little understanding of, and poor attitudes about, that interdependence. Development education helps people better understand and appreciate the international development issues which affect their daily lives. Responding to this perceived need for development education, Communications for Development (CFD), a non-profit coalition of development and media professionals, has produced a broad-based, multi-media learning package entitled "What's a Developing Country?". This development education package consists of a series of exercises supported by handouts, a slide-tape presentation, and a 100-page facilitator's manual, including an annotated bibliography. "What's a Developing Country?" is designed to be used by teachers and facilitators with high school-age and older participants in a variety of settings. This dissertation research focused on the field trials conducted for formative evaluation of "What's a Developing Country?". The purposes of the field trials were to gather information about the ability of the learning program to achieve desired results and to discover what improvements, if any, were needed in the program. Field trials were conducted with three representative groups: high school students, university students, and an adult education group. Formative evaluation data were gathered via pre-/post-tests, standardized feedback forms, standardized observer forms, and facilitators' journals. The field trials had three chief results. First, the program was validated in terms of the achievement of learning objectives and in terms of basic design, content, materials and methodology. Second, the field trials provided a rich source of recommendations for improving program effectiveness. Third, the field trials served to highlight unresolved issues which indicate the need for further data collection and analysis. "What's a Developing Country?" is the first in a series of development education materials planned by Communications for Development. The design and production of these future materials have also benefited from the field trials of "What's a Developing Country?". A basic model has been developed and validated, and lessons learned in the field trials can be applied to future development education packages.

description: In confronting the global spread of the coronavirus disease COVID-19 pandemic we must have coordinated medical, operational, and political responses. In all efforts, data is crucial. Fundamentally, and in the possible absence of a vaccine for 12 to 18 months, we need universal, well-documented testing for both the presence of the disease as well as confirmed recovery through serological tests for antibodies, and we need to track major socioeconomic indices. But we also need auxiliary data of all kinds, including data related to how populations are talking about the unfolding pandemic through news and stories. To in part help on the social media side, we curate a set of 2000 day-scale time series of 1- and 2-grams across 24 languages on Twitter that are most 'important' for April 2020 with respect to April 2019. We determine importance through our allotaxonometric instrument, rank-turbulence divergence. We make some basic observations about some of the time series, including a comparison to numbers of confirmed deaths due to COVID-19 over time. We broadly observe across all languages a peak for the language-specific word for 'virus' in January 2020 followed by a decline through February and then a surge through March and April. The world's collective attention dropped away while the virus spread out from China. We host the time series on Gitlab, updating them on a daily basis while relevant. Our main intent is for other researchers to use these time series to enhance whatever analyses that may be of use during the pandemic as well as for retrospective investigations.

description: We present sub-millimeter statistical detections of galaxies discovered in the 5'x5' Spitzer Early Release Observations (to 4-15 microJy 5 sigma at 3.6-8 microns, 170 microJy at 24 microns) through a stacking analysis of our reanalysed SCUBA 8mJy survey maps, and a Spitzer identification of a new sub-millimeter point source in the 8mJy survey region. For sources detected at 5.8 or 8 microns (154 and 111 sources respectively), we detect positive skews in the sub-millimeter flux distributions at 99.2-99.8% confidence using Kolmogorov-Smirnov tests, at both 850 microns and 450 microns. We also marginally detect the Spitzer 24 micron galaxies at 850 microns at 97% confidence, and place limits on the mean sub-millimeter fluxes of the 3.6 and 4.5 micron sources. Integrating the sub-millimeter fluxes of the Spitzer populations, we find the 5.8 micron galaxies contribute 0.12 +/- 0.05 nW/m^2/sr to the 850 micron background, and 2.4 +/- 0.7 nW/m^2/sr to the 450 micron background; similar contributions are made by the 8 micron-selected sample. We infer that the populations dominating the 5.8 and 8 micron extragalactic background light also contribute around a quarter of the 850 micron background and the majority of the 450 micron background.

description: The projected reach of direct electroweakino searches at the HL-LHC ($\sqrt{s}=14~{\rm TeV}, ~3000~{\rm fb^{-1}}$ LHC) in the framework of simplified models with R-parity violating (RPV) operators: $λ_{112}^{\prime \prime}u^{c}d^{c}s^{c}$ and $λ_{113}^{\prime\prime}u^{c}d^{c}b^{c}$, is studied. Four different analysis channels are chosen: $Wh$ mediated $1l+2b+jets+\rm E{\!\!\!/}_T$, $Wh$ mediated $1l+2γ+jets+\rm E{\!\!\!/}_T$, $WZ$ mediated $3l+jets+\rm E{\!\!\!/}_T$ and $WZ$ mediated $3l+2b+jets+\rm E{\!\!\!/}_T$ and the projected exclusion/discovery reach of direct wino searches in these channels is analyzed by performing a detailed cut based collider analysis. The projected exclusion contour reaches up to $600-700~{\rm GeV}$ for a massless bino-like $χ_{1}^{0}$ from searches in the $Wh$ mediated $1l+2b+jets+\rm E{\!\!\!/}_T$, $Wh$ mediated $1l+2γ+jets+\rm E{\!\!\!/}_T$ and $WZ$ mediated $3l+jets+\rm E{\!\!\!/}_T$ channels, while the $WZ$ mediated $3l+2b+jets+\rm E{\!\!\!/}_T$ search channel is found to have a projected exclusion reach up to $600~{\rm GeV}$ for $150~{\rm GeV} < M_{χ_{1}^{0}} < 250~{\rm GeV}$. The baryon number violating simplified scenario considered in this work is found to furnish a weaker projected reach (typically by a factor of $\sim 1/2$) than the R-parity conserving (RPC) case. The projected reach at the HL-LHC in these four channels is also recast for realistic benchmark scenarios.

description: This research studied the tensile properties of glass fiber reinforced unsaturatedpolyester with different fiber volume fraction Vf, and angle of fibers for coarse andfine woven fibers reinforcement. The composite specimens were prepared by handlay-up technique and cutting according to (ASTM D – 638) for tensile test to obtainmodulus of elasticity, ultimate tensile strength and elongation percentage of thecomposite specimens. Mathematical models were done by using statistical analysiswhich shows the tensile properties of the composite specimens as a function ofvolume fraction and fiber angle.The results show that the maximum value of the modulus of elasticity was (11.5GPA) and the maximum value of ultimate tensile strength was (240 MPa) whichhapped at (11% VF) for fine woven fibers and for (0º/90º) fibers angle, and vice versafor percentage elongation was (2.5%).

description: Using density functional molecular dynamics simulations, we analyze the broken chemical order in a GeS$_2$ glass and its impact on the dynamical properties of the glass through the in-depth study of the vibrational eigenvectors. We find homopolar bonds and the frequencies of the corresponding modes are in agreement with experimental data. Localized S-S modes and 3-fold coordinated sulfur atoms are found to be at the origin of specific Raman peaks whose origin was not previously clear. Through the ring size statistics we find, during the glass formation, a conversion of 3-membered rings into larger units but also into 2-membered rings whose vibrational signature is in agreement with experiments.

description: The identification of individual and institutional drivers regarding ecological transition of individual behaviors has been widely studied in the literature. However, few studies report the specific case of private gardening practices, even though it is particularly relevant when discussing lifestyle habits and ecological transition, due to the wide range of positive and negative environmental externalities private gardens may generate. Using a European database (Eurobarometer 83.4), we estimate individual and institutional drivers of sustainable gardening practices. Our econometric approach takes the specificities of our data into account, by using a two-step approach combining a generalized Heckman model and a meta-regression, and allows us to highlight the importance of the accessibility to biodiversity-related information in the adoption of environmentally friendly behaviors. Differentiated trends between European countries are tested using indicators on economic development, social capital and environmental performances. In conclusion, we provide some recommendations in terms of public policies.

EFFECTS OF DIDACTIC LECTURE, NOVICE AND EXPERT MODELS, AND SELF-OBSERVATION VIA VIDEOTAPE, ON THE ACQUISITION OF BASIC THERAPY SKILLS (PSYCHOTHERAPY, TRAINING, SUPERVISION, MODELING, MICROCOUNSELING)
Creators: name: Baum, Barbara E.
Publisher: name: American University
Year: 2023

description: Four methods of teaching minimal encourages, open-ended questions, and reflective statements were compared for effectiveness both in increasing the use of the skills and improving confidence and anxiety levels of the trainee. Subjects were 48 female psychology students with no prior training in counseling. They were randomly divided into four groups, which differed only as to which training tape they viewed: (1) an experienced therapist lecturing on the use of the skills, (2) an experienced therapist modeling the skills in a client interview, (3) a trainee attempting to use the skills with a client, or (4) the tape of the subject's own pretest interview. All groups also read a manual describing the three skills. Subjects interviewed one mock client before training and one after. Videotapes of the pretest and posttest interviews were compared for change in the use of the target skills. The Session Evaluation Questionnaire, State-Trait Anxiety Inventory A-State Scale, and a Subject Questionnaire designed for this study were completed by subjects after each interview and compared for changes in feelings during the interview and for satisfaction with training. From pretest to posttest, each group improved (p < .004) in use of listening skills. No groups improved significantly on any of the feelings measures. Although differences among groups did not reach the criterion set for significance, several trends emerged. Those observing the expert model showed greatest improvement of all groups in use of listening skills and reduction of anxiety. Those watching videotapes of their own work improved least of the four groups on all measures of both skill and feelings during the interviews. In contrast, they reported the most positive feelings about being videotaped and about the experiment. These findings cast some doubt on the claims made in the literature in praise of self-observation on videotape as a training tool for therapists, since it is clear that praise of the method does not necessarily coincide with improvement in either skill or confidence. The results support more widespread use of expert modeling than the literature indicates is currently done.

THE EFFECTS OF TEACHER SEX EQUITY AND EFFECTIVENESS TRAINING ON CLASSROOM INTERACTION AT THE UNIVERSITY LEVEL (EXCELLENCE, INVOLVEMENT, SALIENT, SILENT STUDENTS)
Creators: name: Long, Joan Elizabeth
Publisher: name: American University
Year: 2023

description: This Static-Group Comparison Study provides a data-based analysis for determining if the independent variable, training of college professors in sex equitable and effective interaction skills, significantly changes the nature of teacher-student interaction in the experimental classrooms as compared to a matched control group. Total sample size was 46 professors and classrooms at an urban university. Twenty-three experimental professors participated in a 2 1/2-day training workshop which focused on (1) the elimination of sex-biased teacher-student interactions in the classroom; and (2) the distribution, precision, and quality of teacher responses to students' verbal behavior. Each classroom was observed three times resulting in 138 (45-minute) observations. The INTERSECT Observation Instrument was used by five trained observers to code classroom interactions for each observation. Significant differences between the experimental and control groups were found in the frequency of teacher-student interaction. Training increased interaction by 38%, reduced the percentage of salient students who monopolize interaction, and also reduced the percentage of silent or non-participating students. More students participated more equitably in the classrooms of the trained group. Training increased the range and precision of professor reactions to student responses. Over half of the control professors' reactions were in the acceptance category (a non-evaluative, diffuse response such as "uh huh" or "OK"). They used acceptance more often than praise, remediation, and criticism combined. Trained professors used more praise, remediation, and criticism, which give more precise and helpful feedback to students. In investigating gender bias at the postsecondary level, this study revealed significant bias in favor of male students in the control group, while the experimental group approached equity. In summary, the provision of training to college professors in sex equitable and effective interaction skills contributes to the overall goal of excellence in higher education. This training increased classroom interaction, including students' participation, as well as the range and precision of professor reactions to all students. It reduced gender bias in the quantity and quality of interactions.

description: We study particle production in the tachyon condensation process as described by different effective actions for the tachyon. By making use of invariant operators, we are able to obtain exact results for the density of produced particles, which is shown to depend strongly on the specific action. In particular, the rate of particle production remains finite only for one of the actions considered, hence confirming results previously appeared in the literature.

Trained professors used more praise, remediation, and criticism, which give more precise and helpful feedback to students. In investigating gender bias at the postsecondary level, this study revealed significant bias in favor of male students in the control group, while the experimental group approached equity. In summary, the provision of training to college professors in sex equitable and effective interaction skills contributes to the overall goal of excellence in higher education. This training increased classroom interaction, including students' participation, as well as the range and precision of professor reactions to all students. It reduced gender bias in the quantity and quality of interactions.

description: During the summer of 2010 once again National and Regional Design and Technology (D&T), Science, Technology, Engineering, and Maths (STEM) organisations joined forces to present the North West Design and Technology Festival, a free conference for design and technology teachers. Hosted by the Science & Technology Facilities Council (STFC) at the Daresbury Laboratories, Warrington, the original event was the brain child of Paul Abbot whose concept was to provide a provide a forum where achievements of both pupils and teachers from across the North West could be recognised. This article presents the highlights from the festival and showcases some of the curriculum innovation on display from participating schools.

description: Dissociation is a lack of the normal integration of thoughts, feelings, and experiences into the stream of consciousness and memory. The phenomenon occurs to some degree in mentally normal individuals and is thought to be more prevalent in persons with major mental illnesses. The Dissociative Experiences Scale (DES) has been developed to offer a means of reliably measuring dissociation in normal and clinical populations. Scale items were developed using clinical data and interviews, scales involving memory loss, and consultations with dissociation experts. Pilot testing was done to refine the wording and the format of the scale so that it would be more comprehensible to subjects. The scale is a 28 item, self-report questionnaire. Subjects were asked to make slashes on 100 mm lines to indicate where they fall on a continuum for each question. In addition, demographic information (age, sex, occupation, and level of education) was collected so that the connection between these variables and scale scores could be examined. The mean of all item scores ranges from 0 to 100 and is called the DES score. The scale was administered to between 10 and 39 subjects in each of the following populations: normal adults, normal late adolescent college students, and persons suffering from alcoholism, agoraphobia, phobic-anxious disorders, post-traumatic stress disorder, schizophrenia, and multiple personality disorder. Reliability testing of the scale showed that the scale had good test-retest reliability and good split-half reliability. Item-scale score correlations were all significant, indicating good internal consistency. A Kruskal-Wallis test and post-hoc comparisons of the scores of the eight populations gave evidence of the scale's criterion-referenced validity. The scale was able to distinguish fairly well between subjects with dissociative disorders (i.e. multiple personality) and all other subjects. A cutting score of 37 maintained the false positive error rate at 5% while correctly identifying 75% of the subjects with dissociative disorders.

description: After many years of neglect, there is a renewed interest in agricultural mechanization in Africa. Since government initiatives to promote mechanization, e.g., by importing and subsidizing tractors, are confronted with major governance challenges, private-sector initiatives offer a promising alternative. This paper analyzes an initiative of the agricultural machinery manufacturer John Deere and its dealership partner AFGRI to promote smallholder mechanization in Zambia through a contractor model. The analysis focuses on the impact of this initiative on smallholder farmers who receive tractor services and on the demand for hired labor. The analysis is based on a survey of 250 smallholders and focus group discussions using Participatory Impact Diagrams. The results of a Propensity Score Matching (PSM) analysis indicate that farmers who access tractor services for land preparation can almost double their income by cultivating a much larger share of the land that they own. The analysis also suggests that the increased income is used for children’s education and for purchasing more food, but does not result in increased food diversity. The findings indicate that the demand for hired labor increases due to the expansion of the cultivated area and due to a shift from family labor, including that of children, to hired labor. Questions that require further investigation are identified, including policies and strategies to increase the incentives of tractor owners to provide services to smallholders, to use mechanization more effectively to increase land productivity, and to avoid new forms of dependency of agricultural laborers that may result.

description: We present results of a systematic study of the c axis lattice dynamics in single layer Bi2Sr2CuO6 (Bi2201), bilayer Bi2Sr2CaCu2O8 (Bi2212) and trilayer Bi2Sr2Ca2Cu3O10 (Bi2223) cuprate superconductors. Our study is based on both experimental data obtained by spectral ellipsometry on single crystals and theoretical calculations. The calculations are carried out within the framework of a classical shell model, which includes long-range Coulomb interactions and short-range interactions of the Buckingham form in a system of polarizable ions. Using the same set of the shell model parameters for Bi2201, Bi2212 and Bi2223, we calculate the frequencies of the Brillouin-zone center phonon modes of A2u symmetry and suggest the phonon mode eigenvector patterns. We achieve good agreement between the calculated A2u eigenfrequencies and the experimental values of the c axis TO phonon frequencies which allows us to make a reliable phonon mode assignment for all three Bi-based cuprate superconductors. We also present the results of our shell model calculations for the Gamma-point A1g symmetry modes in Bi2201, Bi2212 and Bi2223 and suggest an assignment that is based on the published experimental Raman spectra. The superconductivity-induced phonon anomalies recently observed in the c axis infrared and resonant Raman scattering spectra in trilayer Bi2223 are consistently explained with the suggested assignment.
