title: Anxiety in Malaysian children and adolescents: validation of the Screen for Child Anxiety Related Emotional Disorders (SCARED)

description: Abstract Objective Use of the Screen for Child Anxiety Related Emotional Disorders (SCARED) has increased significantly since its publication. Although the validity of the SCARED is well established, most of the samples investigated primarily comprised Caucasian children and, where available, people from Asian cultures such as China. Furthermore, the instrument’s utility for screening use in community samples has yet to be validated, although it is commonly advocated for this use. The present study addressed the psychometric properties of the SCARED in a community sample of Malaysian children and adolescents. Method A total of 386 participants from an urban area, aged between 8 and 17, completed the 41-item SCARED. Confirmatory factor analysis and exploratory factor analysis were performed to investigate the factor structure of the SCARED. Results Internal consistency ratings for the SCARED’s total and subscale scores were good, except for School Avoidance. The validity of the SCARED was further demonstrated through a significant correlation with the Internalizing subscale of the Strength and Difficulties Questionnaire (SDQ). In contrast with the five-factor structure proposed for primarily Caucasian samples, factor analysis revealed a four-factor structure for this Malaysian sample. Conclusions These research findings support the validity of the SCARED and its utility as a screening tool in a community sample of Malaysian children and adolescents.

title: Between emergency, submersion, and silence: LGBT as a research category in Administration

description: Abstract This article discusses the adoption of the abbreviation LGBT (lesbian, gay, bisexual, transvestite, and transsexual), questioning the representativeness of the groups contained in this acronym in Administration research. Some authors in Brazil state that, although there is the intention to construct a field of research on the subject, the agenda is mostly aimed at research on gay people (CARRIERI, SOUZA and AGUIAR, 2014). Therefore, the research question is: Is it possible to treat identity categories that are so different under the same prism? The article is grounded on (1) a historical version of the constitution of LGBT groups, showing how they are organized and fragmented in Brazil (FACCHINI, 2005); (2) a discussion on the adoption of the LGBT acronym as a universal category, based on the debate about contingent identities (BUTLER, 1998); (3) a literature review of Brazilian Administration using the SPELL database. A total of 34 articles approaching LGBT groups were found. Research on gays predominates while groups of lesbians, transvestites, and transsexuals are underrepresented. It is perceived that, although there are similarities from the point of view that all the identity categories are targets of discrimination and violence (which is justified because they are categories considered deviant), the articles mark the differences between them. It is in these differences that there are possibilities for Administration research to question the adoption of acronyms, such as LGBT, as a universally representative and unified concept.

title: Estimating the productivity of radiologists in Brazil: the search for a benchmark

description: Abstract Objective: To determine the average productivity of radiologists, as measured by number of reports issued per 6-h shift, evaluating variables that could affect the results. Materials and Methods: This was a study utilizing an online questionnaire sent to radiologists affiliated with the Brazilian College of Radiology and Diagnostic Imaging. The questions were related to the demographic profile and professional practice characteristics (form of remuneration, primary imaging method employed, and subspecialty) of the radiologists, as well as their individual productivity (average personal productivity) and the productivity considered reasonable in a 6-h shift. The association between productivity and the practice characteristics of the radiologists was determined by using Poisson regression to calculate the prevalence ratio. Results: A total of 510 radiologists completed the questionnaire. The great majority of the respondents (84%) reported that their remuneration is directly related to their productivity. The productivity varied according to the subspecialty, work environment, and remuneration model. Conclusion: We demonstrated that the productivity of radiologists is associated with the characteristics of their employment. We hope that this study will encourage other studies aimed at evaluating the productive capacity of the radiologists in Brazil, addressing the various functions they perform in their daily routine, including activities other than issuing reports.

title: HIV and syphilis infections and associated factors among patients in treatment at a Specialist Alcohol, Tobacco, and Drugs Center in São Paulo’s “Cracolândia”

description: Abstract Introduction This study describes the epidemiological scenario of human immunodeficiency virus (HIV) and syphilis at the biggest specialist drug addiction center in Brazil. The great challenge is to find strategies to reduce the impact of inequality and discrimination and develop policies to protect individuals living with – or at risk of – infections. Methods During the period from January 1 to May 31, 2016, a cross-sectional study was conducted on which all patients (N = 806) seeking inpatient treatment were enrolled. A structured diagnostic interview and rapid tests were conducted initially, and diagnoses were confirmed by tests conducted at a venereal disease research laboratory (VDRL). Results HIV and syphilis rates were 5.86% and 21.9%, respectively. Women were nearly 2.5 times more likely to have syphilis. HIV infection was associated with unprotected sex (odds ratio [OR]: 3.27, p = 0.003, 95% confidence interval [95%CI]: 1.51-7.11), and suicidal ideation (OR: 6.63, p = 0.001, 95%CI: 3.37-14.0). Although only 1.86% reported injecting drugs at any point during their lifetimes, this variable was associated with both HIV and syphilis. Elevated rates of HIV and syphilis were observed in the context of this severe social vulnerability scenario. Conclusion The risk factors identified as associated with HIV and syphilis should be taken into consideration for implementation of specific prevention strategies including early diagnosis and treatment of sexually transmitted infections (STI) to tackle the rapid spread of STIs in this population.

title: Activated Sludge Model No. 1 (ASM1) applicability for simulation of sanitary sewage and landfill leachate co-treatment in aerated lagoons

description: ABSTRACT The growing necessity for alternative landfill leachate treatment and disposal is a reality in Brazil, mainly when the advancements of the National Policy on Solid Wastes (2010) established goals for replacing dumping grounds with landfills. Due to its simplicity, a usual alternative is to perform co-treatment of municipal sewage and landfill leachate in wastewater treatment plants (WWTPs). This study assessed the applicability of the Activated Sludge Model No 1 (ASM1) to aerated lagoons promoting sewage and leachate co-treating. The simulated scenarios consisted of increasing proportions of leachate addition to the system, ranging from 0 to 10%, and for each of them the development of heterotrophic and autotrophic biomass, COD consumption in different fractions, nitrification, oxygen consumption and alkalinity were evaluated. The simulation results showed that the model was optimistic regarding the treatment system startup and microbial communities adaptation when exposed to increasingly aggressive conditions due to leachate addition. However, it correctly represented the detrimental effects on effluent quality due to recalcitrant organic matter and the issues with maintaining proper nitrification regarding aeration capacity and alkalinity demands. ASM1 has good applicability, therefore, as a tool to qualitatively assess the behavior of WWTP when receiving leachate for co-treatment and corroborates the risks associated with this alternative, however, requiring further modifications and details to optimize real systems.

title: Physical and physiological quality of seeds of Campo Grande Stylosanthes coated with different binder materials

description: ABSTRACT: The binder materials used in seed coating provide adherence of the filler materials onto the seeds. Adequate concentrations of the binder promote good physical characteristics of coating while not impairing seed physiological characteristics. Thus, the objective of this study was to evaluate the type and the concentration of binder materials that allow the best physical and physiological characteristics in coated seeds of Campo Grande Stylosanthes. Seed coating was carried out in a coating pan, using sand as the filling material. The treatments consisted of 2 types of binders mixed in 3 ratios (PVA glue and gum arabic glue, diluted in water, 3:1, 2:1, and 1:1), and uncoated seeds as control. The coated seeds were evaluated for physical and physiological characteristics. The laboratory and greenhouse experiments were arranged in a completely randomized design. Results showed that at the different concentrations used this study, neither the PVA glue nor the gum arabic glue had any effect on the physiological quality of Campo Grande Stylosanthes seeds. However, PVA glue in the ratio of 2:1 provided the greatest surface area, maximum diameter, minimum diameter, and sphericity to coated seeds.

title: Configural Reasoning and Geometric Workspace in the Proof's Problem Resolution

description: Abstract The transition from the first justifications of geometric properties in the school environment to the mathematic proof in a deductive context is an issue widely studied. From the Theory of Paradigms and Geometric Workspace, which provides a framework regarding the institutional environment in which the geometric activity is developed, we use the model of Configural Reasoning to study the resolver's geometric workspace when facing a task of proving a geometric property. We describe the discourse organization of high school students' responses to a four-task questionnaire in which they were asked to prove a geometric property, and we determine the configural reasoning that led them to those responses. This analysis allows us to provide evidence on the transition that students must undergo from their first experimental justifications in Natural Geometry to the valid mathematical reasoning proper of Natural Axiomatic Geometry. The Configural Reasoning is shown as a theoretical model with a great capacity for addressing the articulation between visualization and reasoning.

title: Perspectives of Mathematics Teachers about Humour and its Educational Value

description: Abstract At present, humour has an increasing acceptance and appreciation, because we recognize the positive contributions to the well-being of people in contexts as diverse as health, business, and entertainment. What happens in Education and, in particular, in Mathematics teaching? To answer this question, we designed this quantitative study with a sample of 1088 Iberian mathematics teachers (Portuguese and Spanish), that teach from the early years through to higher education. Through the use of a questionnaire, we seek to find out if Portuguese and Spanish teachers who teach Mathematics, throughout the various levels of education, appreciate humor, what perspective they have of it and its educational value, and if they use it in teaching the discipline. The study also sought to determine if the teaching level in which teachers teach mathematics has an influence on the perception and use of humor for instructional purposes. The study also investigates if there are any significant differences between Portuguese and Spanish teachers in relation to these aspects. The results show that the overwhelming majority of teachers, at all levels of teaching, recognize the meaning of humor, consider that they have a sense of humor, justify its use in mathematics teaching and have already seen it being used or used it in their classes, with the goal of creating a good learning environment and making students think. The study reveals differences among teachers at different levels of teaching, indicating that there is a greater predisposition of teachers in the initial years, in comparison to other years, to value and use humor in mathematics teaching. The study also reveals differences between Portuguese and Spanish teachers, with Portuguese presenting a higher average agreement in most items.

title: The Interface Between the Cognitive Processing Speed and Arithmetic and Reading Performance of 5th and 7thYear Elementary School Students

description: Abstract The literature investigating the interface between cognitive processing speed (PS) and learning mathematics and reading suggests that PS plays a crucial role in this interface. However, controversial results still characterize this field of investigation and, therefore, it is necessary to research for a better understanding of the associations between PS and academic achievement, as well as the relationship between PS and working memory (WM), another fundamental cognitive domain. In order to contribute to this debate, the present study aimed to verify the occurrence of correlation (Spearman) between PS and the following variables: a) numerical competence performance (arithmetic and number sense); b) reading performance; c) working memory (central executive component); d) frequency in the use of arithmetic-fact retrieval strategies; e) number of correct fact retrievals. The research involved 60 students, in the 5th and 7thyears of Elementary School, with average and low performance in arithmetic and reading. The results showed significant and negative associations (less time = higher speed) between the variables, so that PS is associated with both numerical and reading competence, as well as with WM and with the variables related to the fact retrieval strategy. These data indicate that a weakness in PV may become a risk factor for the development of difficulties in those areas. Some educational implications are highlighted as well as the need for more evidence relating the interventions in PS and WM and the performance in arithmetic and reading.
