Building application of solar energy. Study no. 4: Scenarios for the utilization of solar energy in southern California buildings, change 1

Plausible future market scenarios for solar heating and cooling systems into buildings in the area served by the Southern California Edison Company. A range of plausible estimates for the number of solar systems which might be installed and the electrical energy which might be displaced by energy from these systems are provided. The effect on peak electrical load was not explicitly calculated but preliminary conclusions concerning peak load can be inferred from the estimates presented. Two markets are investigated: the single family market and the large power commercial market

Gamma-ray bursts and X-ray melting of material as a potential source of chondrules and planets

The intense radiation from a gamma-ray burst (GRB) is shown to be capable of melting stony material at distances up to 300 light years which subsequently cool to form chondrules. These conditions were created in the laboratory for the first time when millimeter sized pellets were placed in a vacuum chamber in the white synchrotron beam at the European Synchrotron Radiation Facility (ESRF). The pellets were rapidly heated in the X-ray and gamma-ray furnace to above 1400 C melted and cooled. This process heats from the inside unlike normal furnaces. The melted spherical samples were examined with a range of techniques and found to have microstructural properties similar to the chondrules that come from meteorites. This experiment demonstrates that GRBs can melt precursor material to form chondrules that may subsequently influence the formation of planets. This work extends the field of laboratory astrophysics to include high power synchrotron sources.Comment: 8 pages, 10 figures. Proceedings of the 5th INTEGRAL Workshop, Munich 16-20 February 2004.

Moving image production and the pedagogical development of media literacy

The chapter focuses on the film Perfect World (2005), a practice-as-research project undertaken by Kayla Parker and Stuart Moore: see entry listed in Compositions. Watch Perfect World, music video with ecological message: http://vimeo.com/1026553 Book: http://www.c-s-p.org/Flyers/Lights---Camera---Action-and-the-Brain--The-Use-of-Film-in-Education1-4438-3657-5.htmThis chapter states the case for the pedagogical value of moving image production in the development of media literacy. In the context of this chapter, the concept of media literacy is extended to encompass not just the ability to critically 'read' media texts but also involves the practices of 'making' media products and artefacts. Drawing on the experiences of two of the authors' involvement with the Bristol Natural History Consortium's Wild Ideas DVD as a case study, this chapter illustrates the pedagogical value of using media technologies to enable the learning of critical abilities, competencies and skills through the active production of media texts. In concluding, we propose that moving image production work not only contributes to the development of media literacy (a valuable life skill in its own right) but also contributes to personal and social development as well as potentially fostering other transferable skills and competencies for employability and citizenship

Finite-element nonlinear transient response computer programs PLATE 1 and CIVM-PLATE 1 for the analysis of panels subjected to impulse or impact loads

Two computer programs are described for predicting the transient large deflection elastic viscoplastic responses of thin single layer, initially flat unstiffened or integrally stiffened, Kirchhoff-Lov ductile metal panels. The PLATE 1 program pertains to structural responses produced by prescribed externally applied transient loading or prescribed initial velocity distributions. The collision imparted velocity method PLATE 1 program concerns structural responses produced by impact of an idealized nondeformable fragment. Finite elements are used to represent the structure in both programs. Strain hardening and strain rate effects of initially isotropic material are considered

PREDICTORS OF SHS’ CHOICE ON TVL TRACK

Career choice for senior high school programs is a crucial stage among junior high school Filipino students. The purpose of this study is to determine the predictors of Senior High School students’ career choices on Technical-Vocational Livelihood (TVL) in Davao del Sur, Philippines. Adopted survey questionnaires were given to a sample of N=405 grade 10 students from public secondary schools in the Division of Davao Del Sur. The questionnaire was validated by experts contextualizing in the local setting. Mean, Pearson chi-squared and logistic regression were used to determine the predictors of Senior High School students’ career choices on Technical vocational Livelihood track. The results show that the mother’s educational attainment significantly affects the student’s intention to enroll in a Technical-Vocational program. Also, classmates will enroll in the same program show a positive relationship with the students’ enrollment intention. This was followed by a flexible class schedule and various accreditations. School career counselors need to intensify students’ awareness in the career selection process to generate ideas and career alignment, and encourage student’s preferences. Career counseling will provide students with a strong sense of direction and help students determine their strengths, values, passion, and areas of interest.Article visualizations

Psychodynamic psychotherapy for children and adolescents: an updated narrative review of the evidence-base

While the evidence base for psychodynamic therapy with adults is now quite substantial, there is still a lack of research evaluating the effectiveness of psychodynamic therapies with children and young people. Those studies that have been carried out are also not widely known in the field. To help address the second point, in 2011, we carried out a review of the evidence base for psychodynamic psychotherapy for children and adolescents, which identified 35 studies which together provided some preliminary evidence for this treatment for a range of childhood disorders. The present study is an updated review, focusing on research published between March 2011 and November 2016. During this period, 23 additional studies were published, of which 5 were reports on randomised controlled trials, 3 were quasi-experimental controlled studies and 15 were observational studies. Although most studies covered children with mixed diagnoses, there were a number of studies examining specific diagnostic groups, including children with depression, anxiety and disruptive disorders. whilst the quality of studies was mixed, some were well-designed and reported, and overall indicated promising findings. Nevertheless, further high-quality research is needed in order to better understand the effectiveness of psychodynamic psychotherapy across a range of different disorders, and to ensure that services can provide a range of evidence-based treatments for children and young people

Similarities in the temporal properties of gamma-ray bursts and soft gamma-ray repeaters

Magnetars are modelled as sources that derive their output from magnetic energy that substantially exceeds their rotational energy. An implication of the recent polarization measurement of GRB 021206 is that the emission mechanism may be dominated by a magnetic field that originates in the central engine. Similarities in the temporal properties of SGRs and GRBs are considered in light of the fact that the central engine in GRBs may be magnetically dominated. The results show that 1) the time intervals between outbursts in SRG 1806-20 and pulses in GRBs are consistent with lognormal distributions and 2) the cumulative outputs of SGRs and GRBs increase linearly with time. This behaviour can be successfully modelled by a relaxation system that maintains a steady state situation.Comment: To appear in the proceedings of the 2003 GRB Conference, Santa Fe, 4 pages, 4 figure

Feasibility of a self-completed history questionnaire in women requesting repeat combined hormonal contraception.

OBJECTIVE: To measure agreement between the client's and the clinician's responses to questions regarding client history as answered on a questionnaire based on the UK Medical Eligibility Criteria for Contraceptive Use (UKMEC) for combined hormonal contraception (CHC). METHODS: Clients aged 18 years and over, attending a central London community contraceptive clinic requesting a repeat supply of CHC, completed a history questionnaire and an evaluation form. Clinicians then completed their copy of the same questionnaire during the consultation. Percentage agreement and the Kappa statistic were used to assess the level of client-clinician agreement. RESULTS: Data from 328 client-clinician pairs were analysed. Agreement was above 93% for all identified risk factors. There was complete agreement for thrombosis, diabetes, stroke, cancer and liver problems. Least agreement was noted in the recording of migraine and abnormal bleeding. For all risk factors except smoking, the proportion of clients reporting a risk factor was more than the proportion of clinicians reporting a risk factor. No clinically important information relevant to a particular client's use of CHC was missed and none of them would have been wrongly prescribed the CHC based just on their self-completed questionnaires. Most women (97%) were happy with this method of history taking. CONCLUSIONS: A self-completed history questionnaire is acceptable to women and can potentially replace traditional routine medical history taking for continuing CHC. Women completed the questionnaire with a high degree of reliability. There was complete client-clinician agreement on UKMEC Category 4 criteria. Overall, clients reported more risk factors than clinicians, which increases the safety of the questionnaire
