Integrating the Transtheoretical Model: A Quantitative Analysis in the Area of Sun Exposure
The constructs involved in the Transtheoretical Model (TTM) have been shown to have similar relationships to the Stages of Change across a variety of behaviors. While much work has been done investigating the way the constructs interact cross-sectionally and longitudinally, a completely integrated look at all the constructs of the TTM has not yet been successful. This study integrated all constructs of the TTM related to increase of sun protective behavior across three time points.
The sample used in this study is a portion of a sample collected for three larger, multiple behavior intervention studies. Assessments were collected at baseline, 6-, and 12-month intervals. At baseline, these larger samples included 1472 people in worksites, 1816 parents, and 3875 physician patients at risk for sun exposure. Of these, 341 worksite, 4 31 parent, and 1012 physician had data at all three time points with all necessary variables.
Structural equation modeling was utilized to evaluate panel designs involving seven TTM constructs at baseline, 6-, and 12-month time points. Different models were run within each pre-action Stage of Change. Due to the complexity of the model, a step approach was taken to evaluate the relationships among the constructs.
The Precontemplation group showed relationships between Experiential Processes, Pros and sun protective behavior. The Contemplation and Preparation samples both showed important relationships between Cons and Confidence with behavior. There were more significant paths in the Preparation model indicating greater variance possibly due to more stage movement at follow-up time points.
While not all paths found confirm expectations based on the TTM, there was strong support for the theory. Additional work needs to be done to further investigate these relationships among individual stage transitions or transition groups. A better understanding of the empirical relationships between these constructs will help further understanding of the theory and improve interventions based on the TTM
Intrarater and Interrater Reliability of the Soong Classification for Distal Radius Volar Locking Plate Placement
Background: The purpose of this study was to analyze the intrarater and interrater reliability of the Soong classification for volar locking plate placement on a randomly selected, consecutive series of radiographs. Our hypothesis was that the classification would be reliable. Methods: Six physicians of differing levels of training (orthopedic surgery intern to fellowship-trained upper extremity staff) were asked to review 40 radiographs in a random order on 2 separate occasions, 4 weeks apart. All observers graded each image (0, 1, or 2) based on the corresponding Soong grade. A weighted κ was used to determine the intrarater agreement. The interrater agreement was determined using an intraclass coefficient: Results: The intrarater reliability using a weighted κ ranged from 0.229 (95% confidence interval [CI]: 0.048-0.411) to 0.946 (95% CI: 0.840-1.051). The interrater intraclass coefficient for Randomization 1 was 0.944 (95% 0.912-0.967) and Randomization 2 was 0.877 (95% CI: 0.797-0.930). Conclusion: The Soong classification is a reliable tool, both interrater and intrarater, for assessing distal radius volar locking plate placement. The classification system remained reliable despite a randomly selected, consecutive series of images and physician observers of varying levels of training

Hundred photon microwave ionization of Rydberg atoms in a static electric field
We present analytical and numerical results for the microwave excitation of
nonhydrogenic atoms in a static electric field when up to 1000 photons are
required to ionize an atom. For small microwave fields, dynamical localization
in photon number leads to exponentially small ionization while above quantum
delocalization border ionization goes in a diffusive way. For alkali atoms in a
static field the ionization border is much lower than in hydrogen due to
internal chaos.Comment: revtex, 4 pages, 5 figure
Le développement professionnel des enseignants et ses effets positifs sur les apprentissages des élèves
En Nouvelle-Zélande, une attention grandissante a été portée par les décideurs politiques au développement professionnel des enseignants et à la façon dont il améliorait les résultats des élèves. Cette approche permet de développer des pratiques d’enseignement collaboratives, en plaçant les enseignants dans une position d’enquêteur de leurs propres pratiques. Les programmes de développement professionnel ont des effets réels sur l’amélioration de la réussite des élèves dans le domaine de la littératie, notamment en lecture. Ils permettent aux enseignants de mieux identifier leurs besoins de formation à travers une analyse des difficultés des élèves et la mise en œuvre de procédures d’évaluation efficaces.In New Zealand, decision makers are more and more focusing on teachers’ professional development and the way it improves student learning. This approach allows to develop collaborative teaching practices, asking teachers to inquire about their own practices. Professional development programmes have real effects on the improvement of students’ assessments in information literacy and particularly reading. They allow teachers to better identify their professional training needs from an analyses of their students’ difficulties and by setting up efficient assessment procedures.En Nueva Zelanda, los responsables políticos otorgaron una atención cada vez más importante al desarrollo profesional de los docentes así como lo hicieron respecto a la manera mediante la cual éste mejoraba los resultados de los alumnos. Este enfoque permite desarrollar prácticas de enseñanza colaborativas, poniendo a los docentes en una postura de investigadores sobre sus propias prácticas. Los programas de desarrollo profesional tienen verdaderos efectos en la mejora de los logros de los alumnos en el ámbito de la literacia, en particular en la lectura.

The Need for Laboratory Measurements and Ab Initio Studies to Aid Understanding of Exoplanetary Atmospheres
We are now on a clear trajectory for improvements in exoplanet observations
that will revolutionize our ability to characterize their atmospheric
structure, composition, and circulation, from gas giants to rocky planets.
However, exoplanet atmospheric models capable of interpreting the upcoming
observations are often limited by insufficiencies in the laboratory and
theoretical data that serve as critical inputs to atmospheric physical and
chemical tools. Here we provide an up-to-date and condensed description of
areas where laboratory and/or ab initio investigations could fill critical gaps
in our ability to model exoplanet atmospheric opacities, clouds, and chemistry,
building off a larger 2016 white paper, and endorsed by the NAS Exoplanet
Science Strategy report. Now is the ideal time for progress in these areas, but
this progress requires better access to, understanding of, and training in the
production of spectroscopic data as well as a better insight into chemical
reaction kinetics both thermal and radiation-induced at a broad range of
temperatures. Given that most published efforts have emphasized relatively
Earth-like conditions, we can expect significant and enlightening discoveries
as emphasis moves to the exotic atmospheres of exoplanets.Comment: Submitted as an Astro2020 Science White Pape
Oviposition Cues for a Specialist Butterfly–Plant Chemistry and Size
The oviposition choice of an insect herbivore is based on a complex set of stimuli and responses. In this study, we examined the effect of plant secondary chemistry (the iridoid glycosides aucubin and catalpol) and aspects of size of the plant Plantago lanceolata, on the oviposition behavior of the specialist butterfly Melitaea cinxia. Iridoid glycosides are known to deter feeding or decrease the growth rate of generalist insect herbivores, but can act as oviposition cues and feeding stimulants for specialized herbivores. In a previous observational study of M. cinxia in the field, oviposition was associated with high levels of aucubin. However, this association could have been the cause (butterfly choice) or consequence (plant induction) of oviposition. We conducted a set of dual- and multiple-choice experiments in cages and in the field. In the cages, we found a positive association between the pre-oviposition level of aucubin and the number of ovipositions. The association reflects the butterfly oviposition selection rather than plant induction that follows oviposition. Our results also suggest a threshold concentration below which females do not distinguish between levels of iridoid glycosides. In the field, the size of the plant appeared to be a more important stimulus than iridoid glycoside content, with bigger plants receiving more oviposition than smaller plants, regardless of their secondary chemistry. Our results illustrate that the rank of a cue used for oviposition may be dependent on environmental context
Vetting of 384 TESS Objects of Interest with TRICERATOPS and Statistical Validation of 12 Planet Candidates
We present TRICERATOPS, a new Bayesian tool that can be used to vet and
validate TESS Objects of Interest (TOIs). We test the tool on 68 TOIs that have
been previously confirmed as planets or rejected as astrophysical false
positives. By looking in the false positive probability (FPP) -- nearby false
positive probability (NFPP) plane, we define criteria that TOIs must meet to be
classified as validated planets (FPP < 0.015 and NFPP < 10^-3), likely planets
(FPP 10^-1).
We apply this procedure on 384 unclassified TOIs and statistically validate 12,
classify 125 as likely planets, and classify 52 as likely nearby false
positives. Of the 12 statistically validated planets, 9 are newly validated.
TRICERATOPS is currently the only TESS vetting and validation tool that models
transits from nearby contaminant stars in addition to the target star. We
therefore encourage use of this tool to prioritize follow-up observations that
confirm bona fide planets and identify false positives originating from nearby
stars.Comment: Accepted to A
A framework to move forward on the path to eco-innovation in the construction industry: implications to improve firms´ sustainable orientation
This paper examines key aspects in the innovative behavior of the
construction firms that determine their environmental orientation while innovating.
Structural equation modeling was used and data of 222 firms retrieved from the
Spanish Technological Innovation Panel (PITEC) for 2010 to analyse the drivers of
environmental orientation of the construction firms during the innovation process.
The results show that the environmental orientation is positively affected by the
product and process orientation of construction firms during the innovation process.
Furthermore, the positive relation between the importance of market information
sources and environmental orientation, mediated by process and product orientation,
is discussed. Finally, a model that explains these relations is proposed and validated.
Results have important managerial implications for those companies worried about
their eco-innovative focus as the types of actions and relations within firms most
suitable for improving their eco-innovative orientation are highlighted.The authors would like to thank the Spanish Economy and Competitiveness Ministry for its support through the research project (EC02011-27369) and also the Universitat Politecnica de Valencia (SP20140647).Segarra Oña, MDV.; Peiró Signes, A.; Cervelló Royo, RE.
