title: Sheep as a large animal model for cochlear implantation

description: Abstract Introduction In surgical training, large animal models are more suitable as their anatomy is more similar to humans. In otology, there have been relatively few studies about large animal models for surgical training. Objective In this study, we aimed to do a neuroradiologic evaluation and surgical insertion of a cochlear implant electrode array on a sheep head model. Methods Twenty cadaveric sheep heads were studied. A computed tomography scan and neuroradiologic evaluation was performed on each head, obtaining measurements of the inner ear for each sheep. Sheep measurements were compared to those from temporal bone computed tomography scans from 20 female humans. Surgical procedures were first trained with 13 of the sheep temporal bones, after which cochlear implantation was performed on the remaining 7 temporal bones. The position of the inserted electrode array insertion was confirmed by computed tomography scan after the procedure. Results Neuroradiologic evaluation showed that, relative to the 20 female humans, the mean ratio for sheep was 0.60 for volume of cochlea, 0.70 for height of cochlea, 0.73 for length of cochlea; ratios for other metrics were &gt;0.80. For the surgical training, the round window was found in all 20 sheep temporal bones. Computed tomography scans confirmed that electrode insertions were fully complete; the mean value of electrode array insertion was 18.3 mm. Conclusion The neuroradiologic and surgical training data suggest that the sheep is a realistic animal model to train cochlear implant surgery and collection of perilymph samples, but less so for surgical training of mastoidectomy due to pneumatization of the mastoid.

title: Public and private schools: social representations of teachers

description: ABSTRACT The objective of this research is to identify the social representations of teachers about public and private schools. Questionnaires with closed and open questions were applied to 87 teachers who work in formal education institutions in the metropolitan region of São Paulo. Data were analyzed with the support of the Descending Hierarchical Classification. The results pointed to representational elements regarding the public school about the lack of commitment of the parents, the imposition and lack of government support, lack of resources and investments, free education, and teacher devaluation. Regarding the private school, these teachers indicated the existence of institutional and parental support, of financial conditions, of paid teaching and learning, of apostilled content and knowledge for the labor market. It is hoped that discussions of these results will contribute to thinking about effective educational policies for both segments.

title: Enrichment activities experienced by students with high abilities/giftedness

description: ABSTRACT Students with high abilities/giftedness stand out for their superior intelligence or special talent in different areas of knowledge, requiring specialized care. Enrichment activities are educational alternatives planned to serve this public. The aim of this research was to describe the enrichment activities experienced by students with high abilities/giftedness, based on the reports of students themselves, their families, and teachers. Questionnaires and specific protocols were developed and applied for each group of informants. As a result, it was found that students attended few enrichment activities, most of which available in laboratories of a university. They often consisted of exploratory activities, without considering the students’ interest and abilities, not reaching type II and III enrichments, according to reports from all segments.

title: Telework and women: perceptions of work and family life balance

description: Abstract This research discusses the satisfaction and conciliation of professional and family life of women who work in the General Management of Ports, Airports, Borders, and Customs Areas (GGPAF) of the National Health Surveillance Agency (Anvisa). We chose Anvisa for its pioneering role in implementing teleworking, adopted at the institution in 2016. It is a health-related institution, and a high proportion of women work remotely in the Management department - the focus point of the study. Although women working at Anvisa accumulated roles and domestic responsibilities during the pandemic, they opted for the potential of telework. The methodology that underpins the results presented in this article can be characterized as a qualitative approach based on semi-structured interviews. During the analysis, five key categories gained substantial attention: quality of life, family life, productivity and motivation, personal organization, and perception of satisfaction with telework. After transcribing the interviews, we analyzed the data using content analysis. Results showed that women are satisfied with teleworking and perceive benefits and gains in quality of life with teleworking despite the disadvantages of social distancing and the accumulation of household tasks and obligations. The study offers a significant contribution to building the field of knowledge about teleworking before and during the COVID-19 pandemic. Also, the research may help to formulate people management policies that consider the importance of women in the world of work, focusing on the work and family life balance.

title: Perception of calling and turnover intention: the moderating role of perceived mobility

description: Abstract This research aimed to analyze the existence of positive, negative, direct, and indirect relationships (via job satisfaction and self-efficacy) between perceiving a calling and turnover intention, as well as the moderating role of perceived mobility. We used a quantitative approach and data collection from 230 employees. The analysis was conducted using structural equation modeling. The results show a direct and negative effect between perceiving a calling and turnover intention, and between job satisfaction and turnover intention. We identified a direct and positive effect between perceiving a calling and job satisfaction and between perceiving a calling and self-efficacy. Job satisfaction partially mediates the relationship between perceiving a calling and turnover intention. There is no significant effect between self-efficacy and turnover intention in the analyzed sample. The moderating effect of perceived mobility on the relationship between job satisfaction and self-efficacy with turnover intention was not significant.

title: Etiology of early hearing loss in Brazilian children

description: Abstract Introduction Hearing loss etiology depends on the population studied as well as on the ethnicity and the socio-economic condition of the analyzed region. Etiological diagnosis contributes to the improvement of preventive measures and to the early identification of this deficiency. Objective To identify the etiological factors of hearing loss and its prevalence in a tertiary hospital in southern Brazil, to verify the frequency of mutations in GJB2 and GJB6 genes, and to correlate the degree of hearing loss with the etiological factors of deafness. Methods This prevalence study involved 140 children with bilateral sensorineural or mixed hearing loss. Medical history, physical examination, audiometry, and evoked auditory brainstem response were conducted. Imaging and genetic examinations were also performed. Results Etiologies and their prevalence were as follows: (a) indeterminate causes, 31.4%; (b) conditions related to neonatal period, 22.1%; (c) genetic, 22.1%; (d) auditory neuropathy, 10%; (e) other factors (cortical malformation, intracranial hemorrhage, and internal ear malformations), 7.9% and (f) congenital infections, 6.4%. Within the genetic cases, ten homozygous and seven heterozygotes of the 35delG mutation were identified, besides two cases of rare variants of GJB2: p.Try172* and p.Arg184Pro. One case with homozygosis of del(GJB6-D13S1830) was found. Regarding severity of hearing loss, in 78.6% of the cases the degree of hearing loss was profound and there were no significant differences when comparing between etiologies. Conclusion The number of indeterminate etiologies is still high and congenital CMV infection may be a possible cause of undiagnosed etiology for hearing loss. The predominance of etiologies related to neonatal conditions and infectious causes are characteristic of developing countries. The most prevalent mutation was 35delG, the main GJB2 gene, probably because of the European influence in the genotype of our population.

title: The material turn in organizational studies: contributions from “On Justification”

description: Abstract This essay aims to contribute to the debate on the so-called “material turn” in social sciences, more specifically, to sociomateriality in organizational studies, including spatiality. We advocate the proposition of the theory of justification that states that the moments of dispute experienced in organizations are not limited to speeches but use objects and spaces to reaffirm their action logic. The theory of justification is approached considering its application in organizational studies, emphasizing the engagement of objects, things, and spaces that are activated in moments of dispute or test situations in organizations, contributing to the advances of this perspective of analysis. The study offers a perspective that adds to existing research on sociomateriality in organizational studies at different levels of analysis. After discussing the theory of justification, its moral logics, sociomateriality, and space in organizational studies, we show correlated studies and point out paths and reflections for a research agenda on the subject. The debate helps to understand the interaction of materiality with cognition, discourse, and behavior in different organizational dynamics.

title: The effect of anatomical variations of the sinonasal region on maxillary sinus volume and dimensions: a three-dimensional study

description: Abstract Introduction Anatomical variations in the sinonasal region are remarkably common and these variations may have an impact on maxillary sinus development due to their close anatomical adjacency. Objective The aim of this study was to investigate the effect of anatomical variations of the sinonasal region on the width, height, length, and volume of the maxillary sinus. Methods Cone beam computed tomography records of 120 patients were evaluated. Nasal septum deviation angle was measured for each patient and patients were divided into three groups as mild, moderate, and severe. Sinonasal variations such as nasal septum deviation direction, septal spur, concha bullosa, uncinate process pneumatization, middle concha hypertrophy, inferior concha hypertrophy, paradoxical middle concha and presence of septa in the maxillary sinus were registered. Cone beam computed tomography images were transferred to the SimPlant software thus right and left maxillary sinus volumes and dimensions were measured separately. Results There was a negative and statistically significant relationship between age and left maxillary sinus width (p= 0.015). The relationships between gender and maxillary sinus volumes and dimensions were statistically significant (p&lt; 0.05). Although there were significant relationships between the nasal septum deviation severity, middle concha hypertrophy, inferior concha hypertrophy, paradoxical middle concha, and presence of septa and maxillary sinus dimensions; there was no significant relationship between septal spur, nasal septum deviation direction, concha bullosa, uncinate process pneumatization, and maxillary sinus dimensions. No statistically significant relationship could be determined between maxillary sinus volume and anatomical variations of the sinonasal region. Conclusion According to our findings, while certain the variations were found to affect the sinus dimensions; none of the variations was found to be related to the maxillary sinus volume.
