Some astrophysical implications of dark matter and gas profiles in a new galaxy cluster model

Recently, Rasia et al. (2004, MNRAS, 531, 237) proposed a new dynamical model for the mass density profile of clusters of galaxies as a result of a set of high resolution hydrodynamical simulations of structure formation. We investigate the lensing properties of this model evaluating the deflection angle, the lensing potential and the amplification of the images. We give particular attention to the structure and position of the critical curves to see whether this model is able to produce radial and tangential arcs. With this aim we also investigate the effect of taking into account the brightest cluster galaxy in the lensing potential and the deviations from spherical symmetry mimicked by an external shear. We also analyze the implication of the gas density and temperature profiles of the Rasia et al. (2004) model for the properties of the X-ray emission and the comptonization parameter that determines the CMBR temperature decrement due to the Sunyaev-Zel'dovich effect.
Pilot study of 68Ga-DOTA-F(ab′)2-trastuzumab in patients with breast cancer

Objective68Ga-1,4,7,10-Tetraazacyclododecane-N,N′,N′′,N′′′-tetraacetic acid (DOTA)-F(ab′)2-trastuzumab [68Ga-DOTA-F(ab′)2-trastuzumab] has been developed at our institution as a positron imaging reagent for assessing human epidermal growth factor receptor 2 (HER2) expression status by in-vivo imaging. Initial studies on animals demonstrated promising results in the monitoring of treatment response to heat shock protein 90-targeted drugs that inhibit the client protein HER2. We report here our initial clinical experience in the assessment of the toxicity, pharmacokinetics, biodistribution, and dosimetry profile of 68Ga-DOTA-F(ab′)2-trastuzumab with PET/computed tomography using a mean of 236 MBq/5 mg administered intravenously. Materials and methodsA group of 16 women with breast cancer were enrolled in this study. The one patient who did not receive 68Ga-DOTA-F(ab′)2-trastuzumab was excluded from analysis. Both HER2-negative (n=7) and HER2-positive (n=8) cases were studied. Among the latter, seven had undergone trastuzumab treatment previously and one had not. ResultsIt was determined that 68Ga-DOTA-F(ab′)2-trastuzumab was well tolerated, with a T½ of ∼3.6±0.9 h; the critical organ was the kidney, with a mean dose of 0.383 cGy/37 MBq; and tumor targeting was seen in 4/8 patients with HER2-positive disease. ConclusionThe reagent is safe, and assessments through additional studies in a better-defined group of patients, using larger administered masses of antibodies, with a better immunoreactive fraction are needed.
Impact of shelf life on content of primary and secondary metabolites in apple (Malus domestica Borkh.).

In this study, we evaluated the changes in apple fruit quality during shelf life. After a month of cold storage, apples of cultivars "Jonagold" and "Golden Delicious" were exposed to ambient temperatures for 21 d, with subsequent sampling every 3 or 4 d. Fruit firmness, changes in amounts of sugars, malic acid, and phenolics were observed during shelf life. Chemical analyses were done with HPLC-PDA system. An interchange between various sugars was noticed, but in general, the sum of sugars remained at the same level. The content of malic acid remained stable or dropped, resulting in sweeter fruit. Levels of phenolics were more constant in the pulp of both cultivars analyzed, while in the peel, the changes were more pronounced. In the pulp, a peak in the content of hydroxycinnamic acids and flavanols was noticed on the 2nd or 3rd sampling and afterwards, the amounts remained constant. In the peel an initial decrease of all analyzed phenolic groups was observed in both cultivars, however it was more pronounced in "Jonagold. " It can be concluded that changes in primary and secondary metabolites are not the main reason for the lower quality of fruit exposed to ambient temperatures. On the other hand, fruit firmness might be the limiting factor for shelf life duration.
Teacher–child interaction quality as a function of classroom age diversity and teachers’ beliefs and qualifications

ABSTRACT Data from 332 teachers who participated in the National Center for Research on Early Childhood Education study were used to examine the implications of classroom age diversity in preschool programs for teacher interactions with students in areas of instructional and emotional support, and classroom organization. Teachers in early childhood classrooms with greater age diversity within a school year and who experienced an increase in age diversity across years exhibited less optimal teacher–child interactions. The negative effects of age diversity for teacher–child interactions were only noticeable among teachers with fewer years of education and experience, and among teachers whose views of children were less child-centered. When taken together, results indicate that closer attention should be paid to the consequences of classroom age diversity in preschool and that a multi-year perspective on teachers’ classroom experiences would allow for a more nuanced understanding of the quality of teacher–child interactions.
Bilingual Performance on the Boston Naming Test: Preliminary Norms in Spanish and English

A total of 100 young educated bilingual adults were administered the Boston Naming Test (BNT) (Kaplan, Goodglass, & Weintraub, 1983) in both Spanish and English. Three group performance scores were obtained: English only, Spanish only, and a composite score indicating the total number of items correctly named independent of language. The scores for the entire group were significantly greater in English than in Spanish. An additional set of analyses explored individual differences in picture naming performance across the two languages as measured by the BNT. For a subset of the larger group (n = 25) there were significant differences in composite over single language scoring, but no significant differences between Spanish and English. Item analyses of correct responses were conducted in both languages to explore the construct validity of the standardized administration of the BNT with this population. There was much greater variability in responses over the Spanish items for this bilingual group. The results of a correlation analysis of information obtained from the initial questionnaire with the BNT scores in each language is also reported. The practical implications of this preliminary bilingual BNT normative data are discussed.
Hire me: Computational Inference of Hirability in Employment Interviews Based on Nonverbal Behavior

Understanding the basis on which recruiters form hirability impressions for a job applicant is a key issue in organizational psychology and can be addressed as a social computing problem. We approach the problem from a face-to-face, nonverbal perspective where behavioral feature extraction and inference are automated. This paper presents a computational framework for the automatic prediction of hirability. To this end, we collected an audio-visual dataset of real job interviews where candidates were applying for a marketing job. We automatically extracted audio and visual behavioral cues related to both the applicant and the interviewer. We then evaluated several regression methods for the prediction of hirability scores and showed the feasibility of conducting such a task, with ridge regression explaining 36.2% of the variance. Feature groups were analyzed, and two main groups of behavioral cues were predictive of hirability: applicant audio features and interviewer visual cues, showing the predictive validity of cues related not only to the applicant, but also to the interviewer. As a last step, we analyzed the predictive validity of psychometric questionnaires often used in the personnel selection process, and found that these questionnaires were unable to predict hirability, suggesting that hirability impressions were formed based on the interaction during the interview rather than on questionnaire data.
An instrument for broadened risk assessment in antenatal health care including non-medical issues

Introduction Growing evidence on the risk contributing role of non-medical factors on pregnancy outcomes urged for a new approach in early antenatal risk selection. The evidence invites to more integration, in particular between the clinical working area and the public health domain. We developed a non-invasive, standardized instrument for comprehensive antenatal risk assessment. The current study presents the application-oriented development of a risk screening instrument for early antenatal detection of risk factors and tailored prevention in an integrated care setting. Methods A review of published instruments complemented with evidence from cohort studies. Selection and standardization of risk factors associated with small for gestational age, preterm birth, congenital anomalies and perinatal mortality. Risk factors were weighted to obtain a cumulative risk score. Responses were then connected to corresponding care pathways. A cumulative risk threshold was defined, which can be adapted to the population and the availability of preventive facilities. A score above the threshold implies multidisciplinary consultation between caregivers. Results The resulting digital score card consisted of 70 items, subdivided into four non-medical and two medical domains. Weighing of risk factors was based on existing evidence. Pilot-evidence from a cohort of 218 pregnancies in a multi-practice urban setting showed a cut-off of 16 points would imply 20% of all pregnant women to be assessed in a multidisciplinary setting. A total of 28 care pathways were defined. Conclusion The resulting score card is a universal risk screening instrument which incorporates recent evidence on non-medical risk factors for adverse pregnancy outcomes and enables systematic risk management in an integrated antenatal health care setting.
Microscopic Investigations of the Terahertz and the Extreme Nonlinear Optical Response of Semiconductors

In this highly nonperturbative regime, the band dispersion characteristically modifies the response of semiconductor quantum wells and wires. ©2006 Optical Society of America OCIS codes: (190.5970) Semiconductor nonlinear optics including MQW; (190.7110) Ultrafast nonlinear optics
MM--Past, Present, Future

One of the most productive days in my life was the day in 1956 when it was agreed that Merton Miller—then a shy and retiring young man (would you believe it! )—would sit in my graduate course in "Money and Macroeconomics" at Carnegie Institute of Technology. It was an exciting course with excellent students. It took a broad view of the subject. One issue that was covered was the cost of capital as a determinant of the rate of investment. I had been intrigued by the subject ever since attending a National Bureau conference on Business Finance at which I gave a (fairly conventional) paper (Modigliani and Ziman, 1952). But mostly I listened to a paper by David Durand (1952) in which the possibility that financial structure would not affect the market valuation or the cost of capital was suggested, only to be rejected as not relevant to the actual capital markets. In preparing my lecture dealing with the cost of capital, I was able to provide (for a world of no taxes) a sort of proof of Proposition I, based on arbitrage. I reported the result to my class the next day, adding that I didn't really believe my result and there probably was something wrong. But Miller was instantly captured by the result because, he said, he knew of a recent paper (Allen, 1954) which provided empirical support for the result, even though it lacked a convincing rationale. We thus formed,
Development of a WHO growth reference for school-aged children and adolescents.

OBJECTIVE To construct growth curves for school-aged children and adolescents that accord with the WHO Child Growth Standards for preschool children and the body mass index (BMI) cut-offs for adults. METHODS Data from the 1977 National Center for Health Statistics (NCHS)/WHO growth reference (1-24 years) were merged with data from the under-fives growth standards' cross-sectional sample (18-71 months) to smooth the transition between the two samples. State-of-the-art statistical methods used to construct the WHO Child Growth Standards (0-5 years), i.e. the Box-Cox power exponential (BCPE) method with appropriate diagnostic tools for the selection of best models, were applied to this combined sample. FINDINGS The merged data sets resulted in a smooth transition at 5 years for height-for-age, weight-for-age and BMI-for-age. For BMI-for-age across all centiles the magnitude of the difference between the two curves at age 5 years is mostly 0.0 kg/m(2) to 0.1 kg/m(2). At 19 years, the new BMI values at +1 standard deviation (SD) are 25.4 kg/m(2) for boys and 25.0 kg/m(2) for girls. These values are equivalent to the overweight cut-off for adults (> or = 25.0 kg/m(2)). Similarly, the +2 SD value (29.7 kg/m(2) for both sexes) compares closely with the cut-off for obesity (> or = 30.0 kg/m(2)). CONCLUSION The new curves are closely aligned with the WHO Child Growth Standards at 5 years, and the recommended adult cut-offs for overweight and obesity at 19 years. They fill the gap in growth curves and provide an appropriate reference for the 5 to 19 years age group.
Alternative Glycerol Balance Strategies among Saccharomyces Species in Response to Winemaking Stress

Production and balance of glycerol is essential for the survival of yeast cells in certain stressful conditions as hyperosmotic or cold shock that occur during industrial processes as winemaking. These stress responses are well-known in S. cerevisiae, however, little is known in other phylogenetically close related Saccharomyces species associated with natural or fermentation environments such as S. uvarum, S. paradoxus or S. kudriavzevii. In this work we have investigated the expression of four genes (GPD1, GPD2, STL1, and FPS1) crucial in the glycerol pool balance in the four species with a biotechnological potential (S. cerevisiae; S. paradoxus; S. uvarum; and S. kudriavzevii), and the ability of strains to grow under osmotic and cold stresses. The results show different pattern and level of expression among the different species, especially for STL1. We also studied the function of Stl1 glycerol symporter in the survival to osmotic changes and cell growth capacity in winemaking environments. These experiments also revealed a different functionality of the glycerol transporters among the different species studied. All these data point to different strategies to handle glycerol accumulation in response to winemaking stresses as hyperosmotic or cold-hyperosmotic stress in the different species, with variable emphasis in the production, influx, or efflux of glycerol.
Evaluation of the Quality of Learning Objects in the Health Care Area

In Brazil, distance education plays an important role in the training of human resources in the health area. In this context, learning objects, understood as modular digital resources used to support learning, are widely used tools in the process of knowledge construction, although not all are valid resources. To date, the literature does not have a specific instrument in Portuguese to evaluate the quality of learning objects in the health area. In order to fill this gap, this paper describes the search for evidence of validity of internal structure and convergent validity of Equalis-OAS: Scale to evaluate the quality of learning objects in the health area. For the study, Equalis-OAS was applied to professionals and undergraduate students from the different areas of Health Sciences, all participants taking a continuing education health course about Food and Nutrition in Primary Health Care. One thousand and sixty-nine volunteers participated in the study. An Exploratory Factor Analysis revealed that the instrument, which has as its construct “Quality of learning objects for the health area”, covers three dimensions: “Intrinsic Concepts of Learning Objects in the Health Area”, “Educational Characteristics” and “Presentation”. The final instrument consisted of 41 items, which explained 66.8% of the total variance of the scores. The scale had excellent internal consistency indexes (overall scale: α = 0.979; “Intrinsic Concepts of Learning Objects”: α = 0.927; “Educational”: α = 0.947; “Presentation”: α = 0.977). Regarding convergent validation, Pearson’s correlation indicated that Equalis-OAS had a moderate correlation (r=0.59, p<0.01) with LORI version 2.0, translated into Portuguese, an instrument for the evaluation of learning objects in general (i.e., not specific to the health area). These results indicate that Equalis-OAS is an instrument that presents good evidence of validity, indicating its use in the context of health education and research.
Using Multimedia Instruction and Performance Feedback to Improve Preservice Teachers’ Vocabulary Instruction

High-quality, effective vocabulary instruction is essential for supporting all students’ academic success, and it is particularly important for students with disabilities. Teacher preparation programs are faced with the challenge of not only training preservice teachers to provide effective vocabulary instruction across grades and content areas, but also to prepare them to teach students with disabilities. This randomized control trial included 200 preservice teachers. We tested the effects that a combination of multimedia instruction and performance feedback on evidence-based practices for effective vocabulary instruction had on participants’ knowledge and application of those practices. Compared with participants who received traditional lecture and text-based instruction and subjective feedback, we found that the group that received multimedia instruction and performance feedback implemented more of the practices, more frequently and for a longer duration. Implications for research and teacher preparation are discussed.
Exploring the experiences of adolescent students attending a virtual school

In the past 20 years distance education has evolved rapidly. The accessibility to online learning or virtual schools has become a viable option for many students. Virtual schools offer students instructional flexibility regarding time, place, and pace. Improvements in distance education fostered rapid growth of online learning. The number of online learners grew nearly ten-fold from 2001 to 2015 (Clark, 2001; Watson et al., 2015). However, Watson (2016) estimated only 10% of online learners represented full-time virtual school students. Although face-to-face instruction is preferred by most K-12 learners, some learners argued their needs were best met by virtual schools (Green, 2013; Kenyon, 2007; Nehr, 2009; Pleau, 2012; Rice, 2006). Little is known about the lived experiences of public virtual school students. The obscure nature of virtual schools may be related to the private home-based settings and having significantly fewer enrollments compared to supplemental online programs and traditional schools. The purpose of this study was to explore the personal meanings and motivational aspects of being an adolescent middle school student in a particular virtual school. Two phenomenological methods were administered. First, the Descriptive Phenomenological Method in Psychology (Giorgi, 2009) revealed 10 commons essences of being a virtual student in a particular virtual school. Three descriptive themes related to (1) the mutual needs of family members, (2) teacher-directed learning with parental assistance, and (3) selective socialization. The descriptive study led to personal meanings expressed in psychological terms. Secondly, Interpretive Phenomenological Analysis (Smith et al., 2012) was administered to interpret satisfactions and dissatisfactions of the five adolescent virtual student participants. A single theme emerged from the interpretive study relating to student freedoms, guided choices and a sense of self-control. Selfdetermination theory was applied to 10 randomly selected experiences to provide further insight into the motivation of each participant. The support for autonomy, competence, and relatedness was identified along with the students’ levels of self-regulation. The detailed and rich descriptions of lived experiences and self-regulation capabilities were expected to improve the readers understanding of virtual school preference for a small number of adolescent students and their parents.
