Traditional Male Role Norms and Sexual Prejudice in Sport Organizations: A Focus on Italian Sport Directors and Coaches

Despite the common belief that sport is an excellent instrument to promote social inclusion, distal minority stressors, such as homophobic slurs and insulting or degrading comments, are frequently reported in sport contexts. The aim of this contribution was to expand previous knowledge on negative attitudes toward sexual minorities (gay and lesbian people) in sport-related contexts, by examining how staff employed in organizational sport contexts scored on three different dimensions of sexual prejudice toward sexual minority athletes: open rejection (i.e., blatant prejudice), denial of visibility (i.e., negative attitudes toward the coming out), and gendering performance (i.e., gender stereotypes about sport performance and skills). Furthermore, we examined the relationship between traditional norms of masculinity and dimensions of sexual prejudice. The sample consisted of 178 Italian sport directors and coaches who were asked to complete an online survey (70 women and 108 men, mostly aged from 38 to 65 years old). A repeated-measures ANOVA revealed that participants scored higher on denial of visibility, with respect to open rejection and gendering performance, independently of gender and sport role. The structural equation model showed that endorsing traditional male role norms was significantly associated with open rejection and gendering performance, whereas no significant association was found with denial of visibility. The findings provide further evidence that sexual prejudice is prevalent in sport organizations, supporting the importance of raising awareness among sports personnel about prejudiced beliefs that may lead minority people to experience severe stress-inducing situations

Osteoblastoma-like Osteosarcoma of the Cuboid: A Case Report

Osteosarcoma most commonly arises in the long bones of the skeleton, and rarely develops in the bones of the foot. We describe a patient who presented with left foot pain, whose radiographic evaluation revealed a lytic destructive mass in the cuboid bone. A biopsy showed an osteoblastoma-like variant of osteosarcoma and the patient was treated with preoperative chemotherapy and amputation. Osteosarcoma of the foot is uncommon and the literature reveals that it is often associated with a delay in diagnosis

The volumetric star formation law in the Milky Way

Several open questions on galaxy formation and evolution have their roots in the lack of a universal star formation law that could univocally link the gas properties, such as its density, to the star formation rate (SFR) density. In a recent paper we used a sample of nearby disc galaxies to infer the volumetric star formation (VSF) law, a tight correlation between the gas and the SFR volume densities derived under the assumption of hydrostatic equilibrium for the gas disc. However, due to the dearth of information about the vertical distribution of the SFR in these galaxies, we could not find a unique slope for the VSF law, but two alternative values. In this paper, we use the scale height of the SFR density distribution in our Galaxy adopting classical Cepheids (age less than or similar to 200 Myr) as tracers of star formation. We show that this latter is fully compatible with the flaring scale height expected from gas in hydrostatic equilibrium. These scale heights allowed us to convert the observed surface densities of gas and SFR into the corresponding volume densities. Our results indicate that the VSF law rho(SFR) proportional to rho(alpha)(gas)rho SFR proportional to rho gas alphaSFR is valid in the Milky Way as well as in nearby disc galaxies

Low-grade extraskeletal osteosarcoma of the chest wall: case report and review of literature

<p>Abstract</p> <p>Background</p> <p>Low-grade extraskeletal osteosarcomas (ESOS) are extremely rare.</p> <p>Case presentation</p> <p>We present the first case of low-grade ESOS of the chest wall, which occurred in a 30-year-old man. Because of initial misdiagnosis and patient's refusal of surgery, the diagnosis was done after a 4-year history of a slowly growing mass in soft tissues, leading to a huge (30-cm diameter) calcified mass locally extended over the left chest wall. Final diagnosis was helped by molecular analysis of <it>MDM2 </it>and <it>CDK4 </it>oncogenes. Unfortunately, at this time, no surgical treatment was possible due to loco-regional extension, and despite chemotherapy, the patient died one year after diagnosis, five years after the first symptoms.</p> <p>Conclusion</p> <p>We describe the clinical, radiological and bio-pathological features of this unique case, and review the literature concerning low-grade ESOS. Our case highlights the diagnostic difficulties for such very rare tumours and the interest of molecular analysis in ambiguous cases.</p

Khirbet al-Batrawy ceramics. A systematic mineralogical and petrographic study for investigating the material culture

The present paper reports the results of a mineralogical and petrographic study focused on the archaeometric characterization of Early Bronze Age pottery from the archaeological site of Khirbet al-Batrawy (Jordan), dated between 3000 and 2000 BC. Optical microscopy (OM) and X-ray powder diffraction (XRPD) analyses are used to define the nature of the raw material, the technology of the ceramic production and their developing during the centuries. The results allow us to identify 12 petrographic fabrics in which the nature of the inclusions is consistent with the geological surrounding of Khirbet al-Batrawy. The variability observed in the fabrics suggests a technological evolution during the centuries, characterized by a first start-up phase in the ceramic production, followed by a diffuse experimentation in the choice of the starting raw material and a last standardization phase. The co-occurrence of primary calcite, illite, gehlenite and diopside allows hypothesizing a firing temperature lower than 950 °C. A moderate increasing in the firing temperature is observed in the last phases of Batrawy history, suggesting a development of knowledge connected to the firing process

Runoff-generated debris flows: Observation of initiation conditions and erosion–deposition dynamics along the channel at Cancia (eastern Italian Alps)

In the Dolomitic region, abundant coarse hillslope sediment is commonly found at the toe of rocky cliffs. Ephemeral channels originate where lower permeability bedrock surfaces concentrate surface runoff. Debris flows initiate along such channels following intense rainfall and determine the progressive erosion and deepening of the channels. Sediment recharge mechanisms include rock fall, dry ravel processes and channel-bank failures. Here we document debris flow activity that took place in an active debris flow basin during the year 2015. The Cancia basin is located on the southwestern slope of Mount Antelao (3264 m a.s.l.) in the dolomitic region of the eastern Italian Alps. The 2.5 km2 basin is incised in dolomitic limestone rocks. The data consist of repeated topographic surveys, distributed rainfall measurements, time-lapse (2 s) videos of two events and pore pressure measurements in the channel bed. During July and August 2015, two debris flow events occurred, following similarly intense rainstorms. We compared rainfall data to existing rainfall triggering thresholds and simulated the hydrological response of the headwater catchment with a distributed model in order to estimate the total and peak water discharge. Our data clearly illustrate how debris entrainment along the channel is the main contributor to the overall mobilized volume and that erosion is dominant when the channel slope exceeds 16°. Further downstream, sediment accumulation and depletion occurred alternately for the two successive events, indicating that sediment availability along the channel also influences the flow behaviour along the prevailing-transport reach. The comparison between monitoring data, topographical analysis and hydrological simulation allows the estimation of the average solid concentration of the two events and suggests that debris availability has a significant influence on the debris flow volume. © 2020 John Wiley &amp; Sons, Ltd

Fibroma desmoplásico, reporte de un caso y revisión de la literatura

ResumenEl fibroma desmoplásico es una lesión neoplásica relativamente rara. Se considera un tumor primario de hueso, que se presenta comúnmente en la región mandibular. Se define como un tumor benigno caracterizado por la formación de abundante matriz y fibras colágenas. En marzo de 2004 se presenta el caso de un paciente de 15 años, varón, con aumento gradual en la región derecha de la mandíbula de 4 meses de evolución. Se manifiesta asintomático, con aumento de volumen, con una apariencia radiográfica y tomográfica bien delimitada radiolúcida. A la exploración se observa un infiltrado a través de la cortical lingual. La lesión es similar a las descritas en la literatura de fibroma desmoplásico.AbstractDesmoplastic fibroma (fibromatosis) is rarely seen a primary tumor of bone. Its occurrence as a central lesion in the jaws is even more uncommon. It is rare tumor of bone, especially in the mandibule. In march 2004, a 15 year-old boy presented, with a 4 month history of gradual enlargement of the right mandibule. Painless intraoral and extraoral swelling, the cortical plate of bone overlying the lesions is expanded with thinning, erosion, and infiltration into the surrounding tissues. The lesion is similar to the one described on the articule
