Not Small Technicalities: Gender's Impact on Choosing Careers in Science, Technology, Engineering and Mathematics

Indiana University-Purdue University Indianapolis (IUPUI)This exploratory study looks at the underrepresentation of certain groups, especially women, in science, technology, engineering and math (STEM) occupations. Using longitudinal data, it investigates the impact of math and technical abilities as well as social status measures such as sex, race/ethnicity and household income on STEM career choice, arguing that social status variables have an important influence apart from abilities, with an emphasis on gender. Results show significant impacts of sex, race/ethnicity, income and both math and technical skills on STEM career choice; however, only sex, math and technical skill have statistically significant impacts when controlling for all other variables, with technical skill having the strongest impact in all tests. Implications of these findings are discussed, confirming previous studies but also setting the groundwork for inclusion of technical skill in research on STEM areas. Future efforts are argued to focus on technical ability, as well as gender and mathematical adroitness

Manganese evolution in Omega Centauri: a clue to the cluster formation mechanisms?

We model the evolution of manganese relative to iron in the progenitor system of the globular cluster Omega Centauri by means of a self-consistent chemical evolution model. We use stellar yields that already reproduce the measurements of [Mn/Fe] versus [Fe/H] in Galactic field disc and halo stars, in Galactic bulge stars and in the Sagittarius dwarf spheroidal galaxy. We compare our model predictions to the Mn abundances measured in a sample of 10 red giant members and six subgiant members of ω Cen. The low values of [Mn/Fe] observed in a few, metal-rich stars of the sample cannot be explained in the framework of our standard, homogeneous chemical evolution model. Introducing cooling flows that selectively bring to the cluster core only the ejecta from specific categories of stars does not help to heal the disagreement with the observations. The capture of field stars does not offer a viable explanation either. The observed spread in the data and the lowest [Mn/Fe] values could, in principle, be understood if the system experienced inhomogeneous chemical evolution. Such an eventuality is qualitatively discussed in this paper. However, more measurements of Mn in ω Cen stars are needed to settle the issue of Mn evolution in this cluste

Separaxion anxiety in pediatric migraine without aura: A pilot study

Background: Separation anxiety (SA) can be defined as the fear reaction and protest manifested by children when the main caregivers move away from him/her or in front of unfamiliar person. SA near eight months may be considered as an important and normal phase of the correct and typical social neurodevelopment. Aims of the present pilot study is assessing the prevalence of separation anxiety in a population of patients with migraine without aura (MwA). Materials and methods: 119 children (69 males) suffering from MwA (mean age 1.78 ± 7:59) were consecutively recruited. The control population consisted of 231 (114 males) healthy subjects similar for age (7.64 ± 1:34; p = 0.768) and gender (p=0.987) The Screen for child anxiety related emotional disorders (SCARED) test was used to assess the prevalence of separation anxiety among MwA children. Results: Healthy individuals are on average less affected (mean 4.72 ± 0:32) of the Separation Anxiety Disorder respect of MwA children (mean 6.83 ± 0.97; p < 0.001) (Figure 1). Conclusion. MwA presents many psychiatric comorbidities and among ones separation anxiety may be considered in the clinical and therapeutic management of pediatric primary headache

Il Barocco e l’antico.: Roma e i suoi monumenti antichi nell’età barocca.

This study aims to analyse the use of Roman antiquities, (ancient buildings, monuments and works of art) in the definition of the urban space of the city of Rome during the Baroque period, and the influence that these antiquities had on the design and realisation of the architectural and artistic works of the main exponents of Baroque taste, especially Bernini, Borromini and Petro da Cortona. Divided in the dispute between the Classical and Baroque currents, which was very strong especially in Rome, many artists of the two factions had as a starting point precisely the study of antiquities, as evidenced by their biographical notes, the study of preparatory drawings of artworks and architectural projects.  This basic study of antiquities would later be developed through the individual creative process of the sculptors/architects/painters and lead to the birth and realisation of what is known as Baroque Rome.Questo studio vuole analizzare l’utilizzo delle antichità romane, (edifici antichi, monumenti e opere d’arte) nella definizione dello spazio urbano della città di Roma durante il periodo barocco, e l’influenza che queste antichità ebbero nella progettazione e nella realizzazione delle opere architettoniche e artistiche dei principali esponenti del gusto barocco, Bernini, Borromini e Pietro da Cortona. Divisi nella contesa tra corrente classica e quella barocca, molto forte soprattutto a Roma, molti artisti delle due fazioni ebbero come punto di partenza proprio lo studio delle antichità, come evidenziano le loro notizie biografiche, lo studio dei disegni preparatori delle opere e dei progetti architettonici.  Questo studio di base delle antichità verrà poi sviluppato attraverso il processo creativo individuale degli scultori/architetti/pittori e porterà alla nascita e alla realizzazione di quella che viene definita Roma Barocca

The definitive version was published in Molecular Ecology Notes 5 (2005): 567-568, doi:10.1111/j.1471-8286.2005.00996.x.Interest in bay scallop conservation has resulted in organized stock enhancement efforts and increased attention to fisheries management issues. Genetic markers can facilitate the monitoring of enhancement efforts, characterization of wild populations, and optimize hatchery practices. We have identified eight polymorphic simple sequence repeat markers including one dinucleotide, six trinucleotide and one compound dinucleotide repeats, in expressed sequence tags generated from multiple bay scallop cDNA libraries. The numbers of alleles range from two to five. The expected and observed heterozygosities range from 0.093 to 0.720 and 0.095 to 0.600, respectively.This project was supported by National Research Initiative Competitive Grant no. 2003-35206-12834 from the USDA Cooperative State Research, Education, and Extension Service and by a grant from the County of Barnstable Massachusetts, USA (both to SBR)

Use of cinacalcet in nephrolithiasis associated with normocalcemic or hypercalcemic primary hyperparathyroidism: Results of a prospective randomized pilot study

OBJECTIVES: To evaluate, by means of a prospective randomized study, the efficacy of cinacalcet in the forms of nephrolithiasis associated with primary hyperparathyroidism in both the hypercalcemic and normocalcemic variant. MATERIALS AND METHODS: Ten patients suffering from active nephrolithiasis associated with primary hyperparathyroidism (4 hypercalcemics and 6 normocalcemics), equally divided between males and females, were randomly but not blindly addressed to treatment with potassium citrate and allopurinol, or to the same therapeutic regimen in combination with cinacalcet. The dosage of cinacalcet was optimized for each patient in order to obtain a reduction of parathyroid hormone (PTH) within normal limits while enabling the maintenance of adequate calcemic values. All study participants were given the same diet based on a reduction in sodium intake, oxalate-rich foods and animal protein with standardized intake of calcium and an increase in hydration. After a follow up period of 10 months , cinacalcet was associated to standard therapy and diet in patients who were not taken it, conversely cinacalcet was withdrawn in the remaining patients who remained on standard therapeutic regimen and diet. Follow up was continued for a second period of observation of the same duration of the first. RESULTS: At the end of the period of treatment with cinacalcet, for both variants of hyperparathyroidism, a statistically significant reduction in the overall number and in the diameter of renal stones was found. CONCLUSIONS: This prospective randomized study shows the effectiveness of cinacalcet used in combination with a diet with normalized calcium intake, in reducing the number and size of urinary stones in hypercalemic and normocalcemic forms of primary hyperparathyroidism

Changes in dietary preferences: new challenges for sustainability and innovation

The transformations in dietary habits that have occurred over recent decades draw attention to important issues concerning the relationship between lifestyles, diet and health, and open up new challenges for operators in the agricultural and food sector. This study intends to analyse these evolutions, comparing the dietary preferences of generation X in 2001 with its dietary preferences in 2011, and those of the following generation, the so-called generation Y. The analysis was conducted by applying latent class clustering to the food spending of a representative sample of Italian consumers. It has enabled us to identify the prevalent food patterns in 2001 and 2011 and to analyse their transformations, interpreting them in the light of social, cultural and economic changes. The comparison of food pattern characteristics over this period highlights the emergence of trends that move in two different directions. The first of these is the rise of a new dietary sensitivity towards a healthy diet rich in fruits, vegetables and fish. The other concerns food patterns that are more vulnerable to diseases related to an unhealthy diet. These trends should draw the attention of public operators to the need for communication campaigns that target specific segments and aim to direct food habits towards healthier behaviours. A change in supply could also help improve the diet, especially if aimed at products with a high level of service provision and at establishments that serve food. Finally, the birth of a niche of consumers particularly drawn towards healthy eating opens the way for the industry to propose a series of innovative products. </jats:p
