Cutting words: Priming self-objectification increases the intention to pursue cosmetic surgery

We examined whether subtle exposure to sexually objectifying cues increases women’s intentions to have cosmetic surgery. Undergraduate women (N = 116) were randomly assigned to a condition in which they unscrambled sentences containing words associated with sexual objectification, non-self-objectifying physicality, or neutral content. Following a manipulation check of these primes, participants reported their body shame and intentions to have cosmetic surgery in the future. Results revealed that priming a state of self-objectification, compared to the two non-self-objectifying conditions, increased both body shame and intentions to have cosmetic surgery. In a mediational model, the link between self-objectification and intentions to have cosmetic surgery was partially mediated by body shame. Controlling for other key intrapersonal and social motives linked to interest in cosmetic surgery did not alter these patterns. These findings highlight the potential for the consumption of cosmetic surgery to stand as another harmful micro-level consequence of self-objectification that may be perpetuated via subtle exposure to sexually objectifying words, even in the absence of visual depictions or more explicit encounters of sexual objectification

Business Cycles, Core and Periphery in Monetary Unions: Comparing Europe and North America

We compare Europe with the USA and Canada as regards business cycle synchronization and core-periphery patterns. A long sample (1950-2005) makes it possible to study how these aspects have evolved over time. Results support the economic viability of EMU. Average cyclical correlations among European countries have risen significantly, reaching levels close to, or even higher than, those of North American regions. Applying fuzzy clustering to the analysis of core-periphery issues, we find Europe to actually outperform North America: the core-periphery divide is milder, and peripheral status seems generally less protracted.European Union, Canada, United States, Monetary Unions, Business Cycles, Fuzzy Clustering.

Modelling the exposure to Cronobacter sakazakii by consumption of a cocoa-milk-based beverage processed by pulsed electric fields

peer-reviewedM.C. Pina-Pérez is grateful to CSIC for providing a DOCTOR contract linked to the INNPACTO project IPT-2011-1724-060000. This study was carried out with funds from BISOSTAD project PSE-060000-2009-003, Generalitat Valenciana I+D+I emergent research groups GV/2010/064 and CYCIT project AGL2010-22206-C02-01.Infants’ exposure (Nf ) to Cronobacter sakazakii via the consumption of infant-rich-inpolyphenols cocoa-milk-based beverages (CCX-M) treated with high-intensity pulsed electric fields (PEF) was evaluated. Monte Carlo simulation enabled the prediction of the variability in C. sakazakii load in beverages at the time of consumption to be estimated. Different scenarios (initial contamination levels; PEF treatment conditions; and time-temperature combinations of CCX-M beverages storage after treatment) were simulated. Cocoa addition and PEF treatment resulted in the most influential input factors to control bacterial final load. Cronobacter spp. exposure risk was reduced by a maximum of 100 times at 95% of iterations due to addition of cocoa at 5 g/100 mL, corresponding to scenario 3 (PEF: 15 kV/cm–3,000 μs; storage 120 h at 8 °C). Moreover, the probability of illness for a healthy population was reduced from 2.15 × 10-8, in the baseline scenario, to 4.78 × 10-10 due to cocoa addition and application of 15 kV/cm–3,000 μs PEF treatment.BISOSTAD projec

La investigación cooperativa

La "Collaborative Research" (Investigación cooperativa) se presenta como una alternativa del diseño "R and D" en Educación y una de las modalidades de la "Action Research". Puede considerarse a E.E.U.U. como país pionero de sus más importantes realizaciones. El artículo intenta presentar una síntesis de la evolución histórica de este tipo de investigación, deteniéndose especialmente en sus orígenes, vinculados a la "Action Research"; la crisis de esta ultima; la creación de los diseños interactivos IR and DT de Tikunoff, Ward y Griffin en 1975 (Interactive Research and Development on teaching) en un contexto internacional favorable al resurgimiento de la Action Research y explicitado en diversidad de corrientes y movimientos orientados a potenciar el cambio educativo y social a través de la investigación; finalmente, su expansión actual. Del estudio de las obras de sus representantes principales (Griffin, Oja, Pine, Smulyan, Tikunoff, Ward, etc.), se extraen los elementos que podemos considerar claves para una definición de la Collaborative Research, los procesos y diseños de investigación empleados y las condiciones requeridas para que pueda llevarse a cabo. A partir de este análisis se ofrece una reflexión sobre los problemas concretos vinculados a este tipo de investigación: los que surgen al inicio de la misma; los que se dan en torno al proceso de comunicación y, sobre todo los relacionados con la producción real de conocimiento científico, señalando en cada uno de estos apartados posibles vías de soluci6n, apuntadas desde los nuevos enfoques de la investigación educativa. * Profesora Catedrática del Departamento de Métodos de Investigación y Diagnóstico en Educación.The Collaborative Research to wants to be as an alternative of the design ((R and D)) in Education and one of some kinds of the Action Research. E.E.U.U. can be considerates as the first country in these works. The article wishes to do a short exposition of the historic evolution of this way of Research for to considerer its beginnings in relation at the Action Research and its last crisis; the establishment of the interactive design IR and DT (Interactive Research and Development on Teaching) of Tikunnoff Ward and Griffin in nineteen seventy five in a international favourable contex for a resurgence of the Action Research for to give a stronger at the educative and social change by the way of the Research; finishment its present. Of the study of the works of their principals figures (Griffin, Oja, Pine, Smulyan, Tikunnoff, Ward, etc.) we can take the elements which we can look as Keys for a definition of the Collaborative Research; the ways and designs of Research useds and the conditions for that the process can be done. After of this, we can think about of the specific problems in relation at this way of Research: those that to come at the beginning of itself; those that are given around of the process of communication, and very much those that are connected with the trust"worthiness of the scientific knowledge showing in every one of these possible ways of solution showeds since the news kinds of the Educational Research

Polyhexamethylene Biguanide and Nadifloxacin Self-Assembled Nanoparticles: Antimicrobial Effects against Intracellular Methicillin-Resistant Staphylococcus aureus

The treatment of skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA) remains a challenge, partly due to localization of the bacteria inside the host’s cells, where antimicrobial penetration and efficacy is limited. We formulated the cationic polymer polyhexamethylene biguanide (PHMB) with the topical antibiotic nadifloxacin and tested the activities against intracellular MRSA in infected keratinocytes. The PHMB/nadifloxacin nanoparticles displayed a size of 291.3 ± 89.6 nm, polydispersity index of 0.35 ± 0.04, zeta potential of +20.2 ± 4.8 mV, and drug encapsulation efficiency of 58.25 ± 3.4%. The nanoparticles killed intracellular MRSA, and relative to free polymer or drugs used separately or together, the nanoparticles displayed reduced toxicity and improved host cell recovery. Together, these findings show that PHMB/nadifloxacin nanoparticles are effective against intracellular bacteria and could be further developed for the treatment of skin and soft tissue infections

Masers and the Massive Star Formation Process: New Insights Through Infrared Observations

Our mid-infrared and near-infrared surveys over the last five years have helped to strengthen and clarify the relationships between water, methanol, and OH masers and the star formation process. Our surveys show that maser emission seems to be more closely associated with mid-infrared emission than cm radio continuum emission from UC HII regions. We find that masers of all molecular species surveyed trace a wide variety of phenomena and show a proclivity for linear distributions. The vast majority of these linear distributions can be explained by outflows or shocks, and in general do not appear to trace circumstellar disks as was previously thought. Some water and methanol masers that are not associated with radio continuum emission appear to trace infrared-bright hot cores, the earliest observable stage of massive stellar life before the onset of a UC HII region.Comment: 6 pages, 3 figures, to appear in the proceedings of IAU Symposium 227: "Massive Star Birth: A Crossroads of Astrophysics", version with full-resolution images available at http://www.ctio.noao.edu/~debuize

Objectification theory predicts college women’s attitudes toward cosmetic surgery

This study investigated cosmetic surgery attitudes within the framework of objectification theory. One hundred predominantlyWhite, British undergraduate women completed self-report measures of impression management, global selfesteem, interpersonal sexual objectification, self-surveillance, body shame, and three components of cosmetic surgery attitudes. As expected, each of the objectification theory variables predicted greater consideration of having cosmetic surgery in the future. Also, as expected, sexual objectification and body shame uniquely predicted socialmotives for cosmetic surgery, whereas self-surveillance uniquely predicted intrapersonal motives for cosmetic surgery. These findings suggest that women’s acceptance of cosmetic surgery as a way to manipulate physical appearance can be partially explained by the degree to which they view themselves through the lenses of sexual and self-objectification
