Prima Facie: four facets of gender bias in personnel selection.

Recent findings have highlighted a ‘perfection bias’, that is women being evaluated on more criteria than men in the workplace (Moscatelli et al., 2020; Prati et al., 2019). However, these studies have not considered faces as stimuli, even if facial first impressions can affect several real-world outcomes (Todorov et al., 2015). On this basis, the present research aimed to verify the presence of a perfection bias at face perception level, employing for the first time all the four facets of the fundamental dimensions of social judgments (i.e., competence, dominance, morality, sociability; Abele et al., 2016) and attractiveness (Hosoda et al., 2003) as evaluation criteria of applicants’ hireability. Four experiments were conducted (total N = 645), employing a gender-neutral position (Study 1) as well as managerial positions (Study 2, 3, 4) and recruiting Italian and British students (Study 1, 2) as well as British workers (Study 3, 4). Results of Study 1 confirmed that male applicants were evaluated only on their facial competence, while female applicants were evaluated on all the other facial traits. However, the other three studies showed a different and unexpected pattern: besides facial attractiveness and competence considered equally important for both male and female applicants, facial dominance was considered as more important in evaluating women, while facial morality and sociability were considered as more important in evaluating men. Hence, results highlighted a sort of ‘deficit bias’, so that counter stereotypic traits in which men and women are believed weak (Fiske, 1998) were more relevant for their hireability.

Aviation English: una lingua per volare Analisi linguistica della comunicazione in aviazione civile

La tesi si propone l'obiettivo di esaminare le caratteristiche della lingua dell'aviazione, il cosiddetto Aviation English (AE), rivolgendo un'attenzione particolare alle dinamiche delle interazioni verbali che avvengono tra piloti e controllori del traffico aereo. A partire da un breve excursus sui diversi tipi di linguaggi, da quelli specialistici alle lingue controllate, si cercherà di fornire una chiara definizione dell'AE, delineando gli aspetti che lo rendono una vera e propria lingua e non una semplice varietà di inglese. La tesi passerà in rassegna tutte le convenzioni e le regole che compongono questa lingua e che rendono la comunicazione in volo efficace a livello internazionale. Si vedrà anche come la comunicazione in aviazione sia suscettibile a molti fattori linguistici (e non), il che comporta per gli operatori del settore, l'obbligo di conoscerla a fondo, più della loro stessa lingua madre. In conclusione, si eseguirà un'analisi conversazionale di una comunicazione terra-bordo-terra realmente avvenuta in un'emergenza. Più precisamente, si tratta dell'estratto del volo US Airways 1549, diventato famoso come "il miracolo dell'Hudson". Questo permetterà di mettere in risalto le regole dell'AE, applicate in un caso concreto, quanto singolare, e notare come queste siano efficaci nel gestire, a livello comunicativo e operativo, gli imprevisti.

Liquid biofuels for aviation: valorisation of the by-product biochar

Biochar is a carbonaceous material produced through pyrolysis of biomass. One promising application of biochar is phosphorus recovery from wastewater. Phosphorus is a vital nutrient for plant growth, but its use in fertilizers often leads to runoff or leaching. Wastewater treatment plants discharge large amounts of phosphorus-rich wastewater, contributing to eutrophication and ecological harm. Biochar can sorb phosphorus, retaining it in solid form. In this thesis, two composites made of biomass and dolomite or shells exhibited superior phosphate sorption compared to biochar alone, reaching up to 100% sorption. Biochar also finds use in soil remediation, specifically in cleaning up contaminated soil. Polycyclic aromatic hydrocarbons (PAHs), which can be carcinogenic and toxic, can be present in soil. Biochar adsorb PAHs, preventing their leakage or bioaccumulation. Hetero-PAHs, a subclass of PAHs with nitrogen, sulfur, or oxygen atoms in their ring structures, are particularly challenging to degrade. Little is known about their behavior or sorption onto biochar. In this thesis, biochar and activated carbon were effective in immobilizing PAHs and hetero-PAHs in real soils, with rates of immobilization reaching 100%. Biochar performed equally or better than activated carbon, offering a cost-effective alternative due to its lower price. Biochar reduce of metal(loid)s mobility in soil. Metal(loid)s like lead, zinc, and arsenic can contaminate soil through industrial sources, agricultural runoff, and other pollution, and are toxic to plants and animals, rendering the soil unsuitable for agriculture. When biochar is added to contaminated soil, it binds to metal(loid)s, preventing leaching into the environment. A biomass-dolomite composite was compared to activated carbon for immobilizing metal(loid)s in contaminated soils. The composite generally outperformed activated carbon and exhibited the ability to immobilize arsenic. In summary, biochar shows promise for phosphorus recovery, soil remediation, and reducing the mobility of heavy metals, offering cost-effective and sustainable solutions to these environmental challenges.

Advancing Bag-of-visual-words Representations For Lesion Classification In Retinal Images.

Diabetic Retinopathy (DR) is a complication of diabetes that can lead to blindness if not readily discovered. Automated screening algorithms have the potential to improve identification of patients who need further medical attention. However, the identification of lesions must be accurate to be useful for clinical application. The bag-of-visual-words (BoVW) algorithm employs a maximum-margin classifier in a flexible framework that is able to detect the most common DR-related lesions such as microaneurysms, cotton-wool spots and hard exudates. BoVW allows to bypass the need for pre- and post-processing of the retinographic images, as well as the need of specific ad hoc techniques for identification of each type of lesion. An extensive evaluation of the BoVW model, using three large retinograph datasets (DR1, DR2 and Messidor) with different resolution and collected by different healthcare personnel, was performed. The results demonstrate that the BoVW classification approach can identify different lesions within an image without having to utilize different algorithms for each lesion reducing processing time and providing a more flexible diagnostic system. Our BoVW scheme is based on sparse low-level feature detection with a Speeded-Up Robust Features (SURF) local descriptor, and mid-level features based on semi-soft coding with max pooling. The best BoVW representation for retinal image classification was an area under the receiver operating characteristic curve (AUC-ROC) of 97.8% (exudates) and 93.5% (red lesions), applying a cross-dataset validation protocol. To assess the accuracy for detecting cases that require referral within one year, the sparse extraction technique associated with semi-soft coding and max pooling obtained an AUC of 94.2 ± 2.0%, outperforming current methods. Those results indicate that, for retinal image classification tasks in clinical practice, BoVW is equal and, in some instances, surpasses results obtained using dense detection (widely believed to be the best choice in many vision problems) for the low-level descriptors.

Micromorphological and hardness analyses of human and bovine sclerotic dentin: a comparative study

The purpose of this study was to test the hypothesis that both human and bovine sclerotic dentin have similar hardness properties, in addition to similar micromorphological characteristics. Sixteen teeth (8 human and 8 bovine) exhibiting exposed dentin in the incisal edge and showing characteristics typical of sclerosis were used. Vickers surface microhardness testing was conducted. Three areas of the dentin surface of each specimen were selected. All teeth were processed for scanning electron microscopy in order to estimate the amount (in percentage) of solid dentin on the sclerotic dentin surface. The data were compared by Student's t test (α = 0.05). The micromorphological and microhardness data were compared by Pearson's linear correlation test (α = 0.05). The mean percentages of solid dentin of human and bovine sclerotic dentin were similar (human 90.71 ± 0.83 and bovine 89.08 ± 0.81, p = 0.18). The mean microhardness value (VHN) of human sclerotic dentin was significantly higher than that of bovine sclerotic dentin (human 45.26 ± 2.92 and bovine 29.93 ± 3.83, p = 0.006). No correlation was found between the microhardness values and the amount of solid dentin in the sclerotic dentin, irrespective of the species considered (human R² = 0.0240, p = 0.714; bovine R² = 0.0017, p = 0.923; and combined R² = 0.038, p = 0.46). We concluded that although both bovine and human sclerotic dentin present a similar amount of solid tissue, human sclerotic dentin presents higher microhardness than bovine sclerotic dentin.

Comparison between cone-beam and multislice computed tomography for identification of simulated bone lesions

There are many studies that compare the accuracy of multislice (MSCT) and cone beam (CBCT) computed tomography for evaluations in the maxillofacial region. However, further studies comparing both acquisition techniques for the evaluation of simulated mandibular bone lesions are needed. The aim of this study was to compare the accuracy of MSCT and CBCT in the diagnosis of simulated mandibular bone lesions by means of cross sectional images and axial/MPR slices. Lesions with different dimensions, shape and locularity were produced in 15 dry mandibles. The images were obtained following the cross sectional and axial/MPR (Multiplanar Reconstruction) imaging protocols and were interpreted independently. CBCT and MSCT showed similar results in depicting the percentage of cortical bone involvement, with great sensitivity and specificity (p < 0.005). There were no significant intra- or inter-examiner differences between axial/MPR images and cross sectional images with regard to sensitivity and specificity. CBCT showed results similar to those of MSCT for the identification of the number of simulated bone lesions. Cross sectional slices and axial/MPR images presented high accuracy, proving useful for bone lesion diagnosis.

Risk indicators for aggressive periodontitis in an untreated isolated young population from Brazil

This study aimed to assess the prevalence of aggressive periodontitis (AgP), and to investigate the association between demographic, socioeconomic and behavioral risk indicators with AgP in an untreated and isolated young population in Southeastern Brazil. For this cross-sectional survey, 134 subjects aged 12-29 years were selected by a census. Of those eligible, 101 subjects received a full-mouth clinical examination, and were interviewed using a structured written questionnaire. Cases were defined as individuals with 4 or more teeth with attachment loss > 4 mm or > 5 mm in the age groups 12-19 and 20-29, respectively. Overall, 9.9% of the subjects presented AgP (10.3% of the 12-19-year-olds and 9.7% of the 20-29-year-olds). The only risk indicator significantly associated with AgP in this isolated population was a high proportion of sites (> 30%) presenting supragingival calculus [OR = 23.2]. Having experienced an urgency dental treatment was a protective factor for AgP [OR = 0.1]. The authors concluded that this isolated and untreated population from Brazil presented a high prevalence of AgP. Local plaque-retaining factors played a major role in the prevalence of AgP in this isolated population, and should be included in further studies evaluating this destructive periodontal disease form.

Formação de profissionais de saúde no Brasil: uma análise no período de 1991 a 2008

Estudo conduzido com o objetivo de contribuir para o planejamento e implementação de políticas de qualificação profissional no campo da saúde. Foram analisados 14 cursos de graduação da área da saúde: biomedicina, ciências biológicas, educação física, enfermagem, farmácia, fisioterapia, fonoaudiologia, medicina, medicina veterinária, nutrição, odontologia, psicologia, serviço social e terapia ocupacional, no período de 1991 a 2008. Dados sobre número de ingressantes, taxa de ocupação de vagas, distribuição de concluintes por habitante, gênero e renda familiar foram coletados a partir dos bancos do Ministério da Educação. Para o curso de medicina, a relação foi de 40 candidatos por vaga nas instituições públicas contra 10 nas privadas. A maioria dos ingressantes era composta por mulheres. A região Sudeste concentrou 57% dos concluintes, corroborando o desequilíbrio de distribuição regional das oportunidades de formação de profissionais de saúde e indicando a necessidade de políticas de incentivo à redução dessas desigualdades.

Etiology of cutaneous leishmaniasis and anthropophilic vectors in Juruti, Pará State, Brazil

In a preliminary study in Juruti, a mining municipality in western Pará State, Brazil, 12 out of 21 patients suspected of presenting cutaneous leishmaniasis showed positive PCR (SSUrDNA and G6PD): Leishmania (Viannia) braziliensis (9/12; 75%) and L. (V.) sp. (3/12; 25%). Entomological studies in the same location revealed the presence of 12 different phlebotomine species (n =105). One of the most common species was Lutzomyia (Psychodopygus) complexa (17%) which is both highly anthropophilic and a known vector of L. (V.) braziliensis in other regions of Pará. These preliminary findings should serve to guide future epidemiological surveillance in Juruti.
