Measurement of the inelastic proton-proton cross-section at √s = 7 TeV with the ATLAS detector
2011
The dependence of the rate of proton–proton interactions on the centre-of-mass collision energy, √s, is of fundamental importance for both hadron collider physics and particle astrophysics. The dependence cannot yet be calculated from first principles; therefore, experimental measurements are needed. Here we present the first measurement of the inelastic proton–proton interaction cross-section at a centre-of-mass energy, √s, of 7 TeV using the ATLAS detector at the Large Hadron Collider. Events are selected by requiring hits on scintillation counters mounted in the forward region of the detector. An inelastic cross-section of 60.3±2.1 mb is measured for ξ>5×10[superscript −6], where ξ is ca…
Spillovers from the oil sector to the housing market cycle
2017
We assess the spillovers from the oil sector to the housing market cycle using quarterly data for 20 net oil-exporting and -importing industrial countries, and employing continuous- and discrete-time duration models. We do not uncover a statistically significant difference in the average duration of booms and normal times in the housing markets of those net oil-importers and net oil-exporters. Similarly, the degree of exposure to commodity price fluctuations does not seem to significantly affect the housing market cycle. However, we find that housing booms are shorter when oil prices increase than housing busts when oil prices decrease. We also show that the net oil-importers are more vulne…
Residencia para la especialización en la docencia hospitalaria: Reflexiones sobre cuestiones curriculares en el posgrado en Educación y Salud
2019
Este artículo, trae a discusión la implementación de un curso de especialización para la formación de profesores para la atención escolar hospitalaria de alumnos gravemente enfermos. Tiene como contexto empírico el curso que se desarrolla en la modalidad de residencia realizado en una universidad pública en la ciudad de San Pablo, Brasil. Nuestro objetivo es identificar y analizar evidencias que surgen durante este proceso de implementación esperando contribuir con la reflexión de trayectorias curriculares posibles durante la formación del profesorado, relacionadas y articuladas con las prácticas y producción de saberes en la frontera de Educación y Salud. En síntesis, considerando la abund…
Obstáculos à produtividade científica de professoras universitárias da área de Ciências da Saúde
2013
To discover the features associated with personal and professional lives of university teachers, in the area of health sciences in the “Comunidad Valenciana” for the period 2003-2007, to learn if they contribute to a greater or lesser scientific productivity. Were interviewed in depth 30 teachers aged between 30 and 60 years in order to identify factors that hamper productivity. Have more difficulties to publish scientific papers, teachers less productive. Represent obstacles: the labor problems, the difficulty to obtain science projects and to publish in certain journals, to balance teaching and research, care work in hospitals, the maternity and children. Although the two groups of large …
Bourdieu en la educación científica: consecuencias para la enseñanza y la investigación
2012
Over the last decades, the development and establishment of a sociocultural approach to science education have led to an increasing interest in other theoretical frameworks such as the sociology of science and the sociology of education of Pierre Bourdieu (1930-2002). With the purpose of contributing to the advancement of the appropriation of Bourdieu’s work by research in science education, this paper presents some of the most important ideas of this author and discusses their implications for science education and research. A lo largo de las últimas décadas, el desarrollo y la consolidación de un abordaje sociocultural a la educación científica han dado lugar a un creciente interés por re…
Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the…
2013
A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb[superscript −1] of pp collision data at s√ = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of various simplified supersymmetry-inspired models where gluinos are pair produced, as well as an mSUGRA/CMSSM model.

Incremental-Entity Personal Conceptions of Intelligence and Individualism-Collectivism in Italian Students
2015
This article examines the relationship between Incremental-Entity personal conceptions of intelligence and the cultural dimension of Individualism-Collectivism in Italian students attending high school. Four types of individualism and collectivism were investigated: 1) Vertical-Individualism, characterized by independent and different self; 2) Horizontal-Individualism, characterized by independent and similar self; 3) Vertical-Collectivism, characterized by interdependent and different self; and 4) Horizontal-Collectivism, characterized by interdependent and similar self. The sample includes 250 students,3th and 5th graders. A battery of tests including a Sociodemographic Questionnaire, the…
Mild cognitive decline. A position statement of the Cognitive Decline Group of the European Innovation Partnership for Active and Healthy Ageing (EIP…
2016
Introduction: Mild cognitive impairment (MCI) is a term used to describe a level of decline in cognition which is seen as an intermediate stage between normal ageing and dementia, and which many consider to be a prodromal stage of neurodegeneration that may become dementia. That is, it is perceived as a high risk level of cognitive change. The increasing burden of dementia in our society, but also our increasing understanding of its risk factors and potential interventions, require diligent management of MCI in order to find strategies that produce effective prevention of dementia. Aim: To update knowledge regarding mild cognitive impairment, and to bring together and appraise evidence abou…
Quality of life of abused older women: moderating influence of coping mechanisms
2019
In 2002, the World Health Organization (WHO) brought global attention to elder abuse and the need for prevention in issuing the Toronto Declaration. With the rise in the proportion of people aged 60 and over, but also the spectacular demographic projections for people aged 80 years and older (globally the number of persons aged 80 and over is expected to triple by 2050), how we age, and how well we age is of great concern. Furthermore, there will be a growing need to protect the most vulnerable older people from harm. For the development of policies and interventions, more insight into this complex phenomenon is required. Therefore, the current chapter examines the effect of abuse on the qu…
