Resolving the Fe XXV triplet with Chandra in Centaurus X-3
2005
We present the results of a 45 ks Chandra observation of the high-mass X-ray binary Cen X-3 at orbital phases between 0.13 and 0.40 (in the eclipse post-egress phases). Here we concentrate on the study of discrete features in the energy spectrum at energies between 6 and 7 keV, that is, on the iron K alpha line region, using the High Energy Transmission Grating Spectrometer (HETGS) on board the Chandra satellite. We clearly see a K alpha neutral iron line at similar to 6.40 keV and were able to distinguish the three lines of the Fe xxv triplet at 6.61, 6.67, and 6.72 keV, with equivalent widths of 6, 9, and 5 eV, respectively. The equivalent width of the Ka neutral iron line is 13 eV, an or…
On the Rock Partridge in the painting “Saint Jerome in the study” by Antonello da Messina.
2012
Pictorial work of Antonello da Messina during the Sicilian period (1455-60) is considered less fruitful and less mature than during his stay in Venice (ca 1474-1476). While some art critics consider the painting “Saint Jerome in the study” a work of the first period, others believe that it was produced during the Venice period. The Authors analysed the plumage characters of the Rock Partridge, Alectoris graeca, depicted with symbolic significance in the painting, to try the identification of the population which the subject used as model could belong to. However, they conclude that the identification as a Sicilian as well as an Alpine Rock Partridge is doubtful and in this case the plumage …
Ingroup Identification Increases Differentiation in Response to Egalitarian Ingroup Norm under Distinctiveness Threat
2017
Previous findings suggest that high identifiers show their group loyalty by deviating from group norms that do not allow the group to react in an adaptive manner towards a threatening outgroup (i.e., when the ingroup norm is egalitarian). In this study, using natural groups (French and North Africans), we aimed at extending our understanding of such loyalty conflict by examining the relationship between ingroup identification and intergroup differentiation (stereotyping and prejudice) as a function of distinctiveness threat and ingroup norms. Results showed a positive relationship between identification and prejudice both in the discriminatory norm condition when intergroup similarity was l…
Drifting through Basic Subprocesses of Reading: A Hierarchical Diffusion Model Analysis of Age Effects on Visual Word Recognition
2016
International audience; Reading is one of the most popular leisure activities and it is routinely performed by most individuals even in old age. Successful reading enables older people to master and actively participate in everyday life and maintain functional independence. Yet, reading comprises a multitude of subprocesses and it is undoubtedly one of the most complex accomplishments of the human brain. Not surprisingly, findings of age-related effects on word recognition and reading have been partly contradictory and are often confined to only one of four central reading subprocesses, i.e., sublexical, orthographic, phonological and lexico-semantic processing. The aim of the present study…
Association Between Group Identification at School and Positive Youth Development: Moderating Role of Rural and Urban Contexts.
2020
These studies are framed within Social Identity Theory and the Positive Youth Development approach. The aim is: (1) to analyze the relationship between group identification at school and key positive development variables (such as self-esteem, self-efficacy, assertiveness, empathy, alexithymia, satisfaction with life, and academic performance); and (2) examine the moderator role of context (rural or urban areas of residence) and sex in these relationships. The samples were composed of 246 adolescents from a rural context (Study 1) and 156 students from rural and urban contexts (Study 2). As proposed in our hypotheses, the results show statistically significant relationships between group id…
Reduction of Gender Identity Stigma and Improvements in Mental Health Among Transgender Women Initiating HIV Treatment in a Trans-Sensitive Clinic in…
2021
Purpose: Stigma toward transgender women (TGW) increases psychosocial vulnerability, leading to poor mental health and affecting access and retention in HIV care. Trans-sensitive health care (TSHC) has the potential to mitigate this adverse impact. This study aimed to describe baseline characteristics in gender identity stigma (GIS), mental health, and substance use among TGW living with HIV initiating antiretroviral treatment and to analyze changes after 6 months in HIV care in a TSHC clinic in Argentina. Methods: Sixty-one TGW living with HIV responded to the following questionnaires at baseline and after 6 months in TSHC: sociodemographic, experiences of GIS (in health care, police, etc.…
Testicular cancer and viral infections: A systematic literature review and meta-analysis
2013
In 1984, Newell and coworkers were the first to suggest that testicular cancer might have a viral etiology since it showed similar characteristics to Hodgkin's lymphoma. A systematic literature review and meta-analysis was conducted to investigate a possible association between viral infections (EBV, CMV, Parvovirus B19, HPV, and HIV) and testicular cancer. Articles published from 1985 through June 2010 were located from MEDLINE and EMBASE databases, 21 articles were finally included in the review. For infection with EBV, CMV, Parvovirus B19, and HIV the pooled OR were 4.80 (95% CI 0.98–23.54), 1.85 (95% CI 0.92–3.70), 2.86 (95% CI 0.35–23.17), and 1.79 (95% CI 1.45–2.21) respectively. No p…
An Iranian booklet: non destructive examination by Energy Dispersive X-Ray Diffractometry and Micro-Raman Spectroscopy
2009
Energy Dispersive X-Ray Diffractometry was used in combination with micro-Raman Spectroscopy to study an undated illuminated Iranian booklet. In both cases, no preliminary preparation of the samples was needed: the data were acquired in a non-destructive way in a natural environment. The book is of particular interest because of the unusual presence of miniatures on some pages. The two techniques were used to collect data from small areas of the pages and in different regions of the miniature in order to identify inks and pigments and to attempt chronological assignment. Raman spectra were affected by strong background fluorescence. In spite of this, different peaks were detected and identi…
Serological and molecular identification of Legionella spp. isolated from water and surrounding air samples in Italian healthcare facilities
2016
Abstract Background Legionella is an intracellular microorganism living in natural and artificial aquatic environments. Although its transmission to humans is linked to the inhalation of contaminated aerosols, there is no validated air sampling method for the control and prevention of the disease. The aim of the present study was to provide more information on the distribution of Legionella spp. in indoor environments and to determine whether the same Legionella strains are isolated from air and water samples. Methods Ten healthcare facilities located in seven regions of Italy were enrolled. The serological typing of Legionella spp. from water samples and the surrounding air by active and p…
Coppie miste in Italia e in Spagna. Uno studio sui fattori che favoriscono il senso di comunità dei partner stranieri
2013
Lo scopo del presente contributo è stato quello di analizzare come l’identificazione etnica (ingroup ed outgroup) e la discriminazione percepita (come straniero o come partner di coppia mista) siano legati al senso di comunità (SdC) dei partner stranieri delle famiglie interculturali residenti in Spagna e in Italia. I risultati mostrano che in entrambi i gruppi l’identificazione con il proprio gruppo etnico-culturale non è associata al SdC. Inoltre, l’aumento della discriminazione percepita come coppia mista porta ad una diminuzione del senso di comunità e della soddisfazione di vita. The aim of this paper was to analyze how ethnic identification (ingroup and outgroup) and perceived discrim…
