Eating Disorders: Prevention, Identification and Treatment in Elementary and Secondary Schools
This study was designed to examine the responses of elementary and secondary school counselors to students with symptoms of eating disorders. A survey was sent to 1000 school counselors in the upper Midwest (Iowa, Minnesota, North Dakota, South Dakota and Wisconsin) during the spring of 2000. The survey contained 1 of 4 vignettes which describe either a male or female student presenting with/without symptoms suggestive of disordered eating patterns. The gender of the student in the vignette was randomly assigned. School counselors were asked to report the classification they would designate, assessment procedures they would utilize, and interventions that they would implement with the student in the vignette. The survey also collected demographic information about the counselors, the schools at which they are employed, and the presence of an eating disorder prevention program. Two hundred sixty-three school counselors returned the survey resulting in a response rate of 26%. Results indicated that school counselors were likely to involve parents and psychologists in the treatment of the eating disordered individual. In addition, the likelihood of having eating disorders prevention program components in place varied by state. The manner in which school counselors respond to students with eating disorders is an important issue as they are likely to be the first mental health professional to come in contact with students with disordered eating patterns. School counselors can play an important role in the prevention, early identification, and treatment of students with disordered eating patterns. Implications of the results of this study are discussed with this in mind
Monitoring of Eschericia. Coli O157 From Raw Cow's Milk in the Storage Tank in Sleman District, YOGYAKARTA
Escherichia coli O157 is a member of Enterobacteriaceae which has somatic antigen O157. E. coli O157 isassociated with life threatening diseases such as hemorrhagic colitis (HC), hemolytic uremic syndrome(HUS) and thrombotic thrombocytopenic purpura (TTP). Raw milk is considered a high risk food as it ishighly nutritious and serves as an ideal medium for bacterial growth. The aim of this study was to monitorE. coli O157 contamination in the storage tank before distribution in Sleman district, Yogyakarta. Totalof 30 raw milk samples were collected from the storage tank in Sleman district. Tryptic Soy Broth (TSB)media added with novobiocin was used as enrichment medium, while Chromocult Coliform Agar (CCA)and Chromagar O157 medium for screening test. Additional analysis including serologic and moleculartest of isolates obtained. Based on the screening result, 11,428 colonies were considered as E. coli O157 suspectthat produced red colour in CCA medium. Further screening employing Chromagar O157 mediumresulted in 3 potential colonies which produce mauve colour. These colonies were later tested with LatexTest O157 for serological reason, showing that none were E. coli O157. Molecular analysis with primer pairsfor detection of Stx1 and Stx2 genes confirm that none of the suspected strains have genes that encodedthe toxin, Stx1 and Stx2. These results showed that the presence of STEC (Shiga toxin E. coli) hasn't foundin the tested samples of raw cow's milk
WFPC2 Observations of NGC 454: an Interacting Pair of Galaxies
We present WFPC2 images in the F450W, F606W and F814W filters of the
interacting pair of galaxies NGC 454. Our data indicate that the system is in
the early stages of interaction. A population of young star-clusters has formed
around the late component, and substantial amounts of gas have sunk into the
center of the earlier component, where it has not yet produced significant
visible star formation or nuclear activity. We have photometric evidence that
the star-clusters have strong line emission, which indicate the presence of a
substantial component of hot, massive stars which formed less than 5-10 Myrs
ago.Comment: 14 pages, 4 figures, Latex (AAS macros), ApJL in pres
Cooperation and development for academic language skills in the university context
Abstract
This paper analyses the learning process of students of a Master's course in Cooperation and Development (C&D) who attend classes in English for Academic Writing at the University of Calabria, and their awareness of competences achieved. The language objectives are to expand students' knowledge of the main elements of spoken and written discourse in English in academic contexts with focus on specialized language in the fields of C&D. The study evaluates the ability of students to improve their competences and assess their language development using the self-assessment grid of academic language competences included in the European Language Portfolio created at the Università della Calabria, Italy. Specifically, this version of the ELP focuses on academic language and contains descriptors aimed at evaluating learners' language competences in academic contexts. A group of 25 students participated in this didactic experience, in the second semester of the academic year 2018. Students' oral production, interaction and academic writing skills were monitored. For the written examination students were required to write a Research Proposal (RP) showing competence in text cohesion and content coherence, appropriate use of terminology and accurate use of language structures. Following on from the acceptance of the RP, students delivered an oral presentation on the topic presented, showing ability in answering questions and expressing opinions on issues presented by other students. The concepts of autonomous learning are crucial in order to monitor students' improvement and commitment. A contrastive analysis of data from students' first self-assessment to the final evaluation of competences achieved by the end of the academic year was conducted

RR LYRAE VARIABLE STARS: PULSATIONAL CONSTRAINTS RELEVANT TO THE OOSTERHOFF CONTROVERSY
A solution to the old Oosterhoff controversy is proposed on the basis of a
new theoretical pulsational scenario concerning RR Lyrae cluster variables
(Bono and coworkers). We show that the observed constancy of the lowest
pulsation period in both Oosterhoff type I (OoI) and Oosterhoff type II (OoII)
prototypes (M3, M15) can be easily reproduced only by assuming the canonical
evolutionary horizontal-branch luminosity levels of these Galactic globular
clusters and therefore by rejecting the Sandage period shift effect (SPSE).Comment: postscript file of 7 pages and 2 figures; one non postcript figure is

Antisense reduction of thylakoidal ascorbate peroxidase in Arabidopsis enhances Paraquat-induced photooxidative stress and Nitric Oxide-induced cell death
The production and characterization of Arabidopsis plants containing a transgene in which the Arabidopsis tAPX is inserted in antisense orientation, is described. tAPX activity in these transgenic tAPX plants is around 50% of control level. The tAPX antisense plants are phenotypically indistinguishable from control plants under normal growth conditions; they show, however, enhanced sensitivity to the O 2- -generating herbicide, Paraquat. Interestingly, the tAPX antisense plants show enhanced symptoms of damage when cell death is triggered through treatment with the nitric oxide-donor, SNP. These results are in accordance with the ones recently obtained with transgenic plants overexpressing tAPX; altogether, they suggest that tAPX, besides the known ROS scavenging role, is also involved in the fine changes of H 2O2 concentration during signaling events
Gaia's Cepheids and RR Lyrae Stars and Luminosity Calibrations Based on Tycho-Gaia Astrometric Solution
Gaia Data Release 1 contains parallaxes for more than 700 Galactic Cepheids
and RR Lyrae stars, computed as part of the Tycho-Gaia Astrometric Solution
(TGAS). We have used TGAS parallaxes, along with literature () photometry and spectroscopy, to calibrate the zero point
of the Period-Luminosity and Period-Wesenheit relations of classical and type
II Cepheids, and the near-infrared Period-Luminosity,
Period-Luminosity-Metallicity and optical Luminosity-Metallicity relations of
RR Lyrae stars. In this contribution we briefly summarise results obtained by
fitting these basic relations adopting different techniques that operate either
in parallax or distance (absolute magnitude) space.Comment: 5 pages, 4 figures, proceedings for the 22nd Los Alamos Stellar
