The perception of brazilian researchers concerning the factors that influence the citation of their articles: A study in the field of sustainability

With growing institutional pressure from the Brazilian government to increase the impact of research that it funds, Brazilian researchers are increasingly interested in discovering factors that affect the citation of their articles. The aim of the present article was to assess the perceptions of Brazilian sustainability researchers to identify factors that influence the impacts of their research. A survey was conducted with researchers in the field of sustainability and 89 questionnaires were completed. All of those researchers have articles or research projects in the field of sustainability (mixing environmental, social and/or economical) recorded in the Scielo or Lattes Curriculum Brazilian databases. Results suggest four factors that may explain the impact of article citations: (1) prestige of the author and the research network; (2) prestige of the means of publication and indexing; (3) accessibility and quality characteristics of the article; and (4) international nature of communication and scope of the study. Surprisingly, such factors were not statistically significant in explaining the citations of the participating researchers. These results show the need to consider other factors that can explain the impact of research, discovering the missing links. © 2013 Elsevier Inc.

Influence of spacing in the upper lateral incisor area on the perception of smile esthetics among orthodontists and laypersons

Background: The aim of this study was to determine the perception of smile esthetics among orthodontists and laypeople with respect to the presence of diastemas in the upper lateral incisor in the mesial, distal, and both surfaces using an oblique smile analysis. Methods: Two standardized oblique photos of pleasant smiles from two white women were selected. Images were digitally altered to create diastemas in the lateral incisor, in 0.5-mm increments, in the mesial, distal, or both surfaces. Final images were randomly assembled in a photo album, which was given to 120 judgesd60 orthodontists and 60 laypersons. Each rater was asked to evaluate the attractiveness of the images on a visual analog scale. The data collected were submitted to statistical analysis by the means of one-way ANOVA with the Tukey post hoc test and the unpaired Student’s t test. Results: The most attractive smile was the one without spacing, and the presence of diastemas was considered unattractive by both groups of raters, following a pattern: the greater and the more mesially located, the more unattractive was the smile. Conclusions: The results of this study suggest that diastemas in the upper lateral incisor area were considered unattractive, following a pattern: the greater and the more mesially located, the more unattractive was the smile.

Perception of Risk of Musculoskeletal Disorders Among Brazilian Dental Students

The aim of this study was to compare the mean scores of perceived risk factors for the development of musculoskeletal disorders in dental students presently pursuing work/study, according to gender, course series, and the presence of pain/discomfort. The participants were 348 students from the undergraduate course in dentistry at a Brazilian public university. The instrument on work-related factors that could contribute to osteomuscular symptoms and part of the Nordic questionnaire were used. The psychometric properties of the first instrument were estimated. A multivariate analysis of variance (MANOVA) revealed that the instrument had a tri-factorial structure (s2 retained: 62.72 percent). The retained factors were repetitiveness, work posture, and external factors. The internal consistency and reproducibility were adequate (α=0.746 to 0.873; p=0.729 to 0.940). Lower mean scores of perceived external factors were observed for the male participants, as well as lower scores in the three dimensions of the instrument for first-year students of the course and for those who did not report pain/discomfort in the neck, feet, and ankles. The authors concluded that the perception of risk factors for musculoskeletal disorders reported in the work/study environment of dental students was significantly related to gender, the course series, and the presence of pain/discomfort.

Perception of brazilian citizens about Darwinism and the (Non) Influence of God in the evolutionary process

The current context is unique in relation to the teaching of evolution in Brazil and the population's perception of evolution. On the one hand, it is said often about Darwinism in various media, especially due to the relatively recent commemoration of the two hundred years of the birth of Charles Darwin and one hundred and fifty years of the launch of the book The Origin of Species. On the other hand, it is clear, in recent years, a timid movement, more worryingly, in favor of equitable approach of creationist and evolutionist theories in the classroom. This article is a part of a research whose goal is to raise the design that Brazilian respondents have about the Darwinian view (which disregards the divine influence in the evolution of the species). The instrument used for data collection is a questionnaire, type Likert scale, which consists of a series of statements in which respondents must express their degree of agreement or disagreement with each statement. In this study, we present the results of the statement. "The thought of Darwin, which does not consider God as a participant in the process of evolution, is...". Analysis correlated with data on religion and education of the respondents are also held. The results point to a tendency of respondents not to accept the Darwinian view that disregards God's interference in the evolutionary process. The data also show that respondents' choices are influenced by religion and education. The frequency of responses that tend to accept the Darwinian view (which disregards the divine participation in the evolution of the species) is higher among respondents with higher levels of education. Adherents to religions "evangelical" tend to deny this view more often than followers of other religions. Given the potential risks of inserting creationist approaches in school education, it is necessary a discussion of the possible impacts of this rejection of Darwin's thinking (which does not consider God as a participant in the evolutionary process), indicated here, in the teaching of evolution.

Care to terminal patients. Perception of nurses from the intensive care unit of a hospital

Objective. To identify the perception of nurses with regard to the process of providing care to patients in the context of hospice care. Method. Qualitative study using the methodological framework Collective Subject Discourse. A total of 18 nursing professionals of the adult intensive care unit of a public hospital in São Paulo, Brazil were interviewed between June and August 2012. Results. The process of providing care to terminal patients is permeated by negative, conflictive and mixed feelings. As regards communication, while the participants acknowledge its importance as a therapeutic resource, they also admit a lack of professional qualification. Conclusion. The interviewees have difficulties to deal with care provided to terminal patients. The qualification of these professionals needs to be improved, starting in the undergraduate program.

Perception of the informed consent form by participants in clinical trials

To understand the perception of the participants in controlled clinical trials (CCTs) about the informed consent and describe the meaning of their participation in the research. Qualitative study using the focus group technique. The sample was composed of 19 patients who participated in clinical trials about hypertension and coronary disease in a specialized cardiologic hospital located in the city of Sao Paulo. The methodological framework used was the content analysis. Some of the participants were aware of the real objective of these studies while others had misperceptions. The reading of the informed consent is not always done and, when it is done, the patient does not understand it. The lack of understanding about the term ''placebo'' was mentioned by some participants. The motivation to participate was the personal benefit. This study shows that obtaining the informed consent in CCTs is complex and that there is the need to adapt the structure and application of this document, in order to protect the participants and improve the quality of clinical trials performed in the country.

Medicinal plants in pregnancy and lactation: perception of the health risk and practical educational group in Araraquara, São Paulo State, Brazil

The use of medicinal plants among pregnant women and lactating is a common practice in diverse countries. However, many medicinal plants are contraindicated during pregnancy and lactating, due to various adverse effects, such as teratogenic, embryotoxic and abortive effects, exposing these women, their fetus and babies to health unknown risks. Thus, the purpose of this commentary, was to analyze the perception about the use of medicinal plants by pregnant women and lactating registered in the "baby on board" NGO, Araraquara, São Paulo state, Brazil, between 2010 at 2013. The group was constituted by 48 women, between the first and last trimester of pregnancy or whilst breastfeeding. Information was collected during group meetings by oral interview, using a questionnaire, as script. The nature of the study was a qualitative analysis. The results were based on reports about the use of medicinal plants by pregnant women during group meetings: use, indication of use, knowledge about risks. All participants received written and oral information about the study and they gave a written informed consent. The use of medicinal plants is a reality among pregnant and lactating women of the "baby on board" NGO. They reported that they feel that "natural" products are not harmful for their health. The primary information sources for the majority of women about medicinal plants during pregnancy are family, neighbors and herbalists. The plants most cited (in popular name in Brazil) were: senna, chamomile, boldo, lemon balm, lemon grass. They were used mainly for: nausea, heartburn, indigestion, flatulence, intestinal and abdominal pain, anxiety, intestinal constipation and low milk production. The pregnant and lactating women lacked knowledge about the health risks of the use of medicinal plants and herbal medicines in pregnancy and lactation. They also reported difficulties in clarifying some questions about the use of medicinal plants with their doctors. The results of the present study showed that educative actions about the rational use of medicinal plants in pregnancy and breastfeeding could be part of the operating protocols to promote the maternal and child health programs in Araraquara. Thus, our results also suggest the importance of creating institutionalized places, to the implementation of continued education programs about rational use of medicinal plants in pregnancy and lactation. These targeted programs are not only for health professionals, but also for community members, pregnant women and breastfeeding. Our results pointed out the importance of guidance of doctors and healthcare professionals on the scientific studies about medicinal plants and herbal medicines and the risk/benefit of using herbs during pregnancy. Finally, it is noted the importance of the health professionals to inform women of childbearing on risks to their health, as well as on possibilities of utilization of herbs during fertile period, giving special attention to the potential risk of self-medication.

Influence of door handles design in effort perception: accessibility and usability

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with different door handles by Portuguese subjects of both genders and different ages. This transversal study agreed with ethical aspects. 180 subjects of both genders pertaining to three age groups have participated. Five door handles with different shapes were evaluated. A subjective numeric rating scale of 5 levels was used to evaluate the effort. For statistical analysis it was applied the Friedman non-parametric test. The results have showed no significant differences of effort perception in door handles "A" and "B"; "A" and "D"; and "D" and "C". Door handle "E" presented the lowest values of all. In general, there's an inverse relationship between the results of biomechanical studies and the effort perception of the same task activity. This shows that door handles design influence directly these two variables and can interfere in the accessibility and usability of these kinds of products.

Health surveys and use of maternal and child health care services in three municipalities within the São Paulo metropolitan area

Objectives. To describe the changes in the use of maternal and child health care services by residents of three municipalities-Embu, Itapecerica da Serra, and Taboao da Serra-in the São Paulo metropolitan area, 12 years after the implementation of the Unified Health System (SUS) in Brazil, and to analyze the potential of population-based health care surveys as sources of data to evaluate these changes.Methods. Two population-based, cross-sectional surveys were carried out in 1990 and 2002 in municipalities located within the São Paulo metropolitan area. For children under 1 year of age, the two periods were compared in terms of outpatient services utilization and hospital admission; for the mothers, the periods were compared in terms of prenatal care and deliveries. In both surveys, stratified and multiple-stage conglomerate sampling was employed, with standardization of interview questions.Results. The most important changes observed were regarding the location of services used for prenatal care, deliveries, and hospitalization of children less than 1 year of age. There was a significant increase in the use of services in the surrounding region or hometown, and decrease in the utilization of services in the city of São Paulo (in 1990, 80% of deliveries and almost all admissions for children less than 1 year versus 32% and 46%, respectively, in 2002). The use of primary care units and 24-hour walk-in clinics also increased. All these changes reflect care provided by public resources. In the private sector, there was a decrease in direct payments and payments through company-paid health insurance and an increase in payments through self-paid health insurance.Conclusions. The major changes observed in the second survey occurred simultaneous to the changes that resulted from the implementation of the SUS. Population-based health surveys are adequate for analyzing and comparing the utilization of health care services at different times.

Quality of life and stimulus perception in patients' rehabilitated with complete denture

The objective of this study was to evaluate and correlate quality of life (QoL), and stimulus perception of complete denture users, before and after the insertion of new prostheses. We selected 60 patients using bimaxillary complete conventional dentures who needed to replace their prostheses. During anamnesis, we collected demographic data and applied the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) questionnaire and stimulus perception questionnaire (PERCEPTION). Before installation of new prostheses, the patients responded to OHIP-EDENT questionnaire, and on the day of installation, they responded to PERCEPTION questionnaire. At the patients 3-month follow-up, we re-administered the OHIP-EDENT and PERCEPTION questionnaires. The Wilcoxon and MacNemar tests were used to compare patient responses between the time points analysed. Most of the OHIP-EDENT items showed a highly significant impact of the new prostheses on oral health (P = 0.003). The PERCEPTION questionnaire data indicated that the patients experienced significant improvements (P < 0.05) in terms of their sensations with the new prostheses. Cross-lagged data analysis did not show any causality between the OHIP-EDENT and PERCEPTION questionnaires (ZPF test, P = 0.772). We concluded that the treatment was effective with respect to the patients QoL and their adaptation to the new prostheses.

Access of children to the oral health service

Dental caries still affect a considerable proportion of children, however the epidemiological profile of oral diseases is changing, social inequalities cause different disease patterns. The same problems occur for the use of services, which damage those who are more susceptible to oral diseases in numerous ways. To verify the association between the variables: socioeconomic condition, oral health and access to dental services providing oral health care for preschool children. The study population consisted of 2,759 children up to 6 years-old. The clinical exams followed the World Health Organization (WHO) criteria. The data were collected using a self-applied questionnaire, answered by the carers of children, with questions about socioeconomic variables and access to dental services. In terms of social class, a majority of the subjects came from the middle socioeconomic level (babies, 84.7%; children, 82.8%). Babies who had caries, 48.4% and 67.2% of the children that had decayed teeth had access to dental service. There was a association between the variables: the reason for the last dental appointment and the parent's perception of the treatment need of their children (babies p=0.0004 and children p < 0.0001); the parent's perception of the treatment need of their children and the oral health condition (babies p=0.0008 and children p < 0.0001); access to dental services and oral health condition (babies p=0.0021 and children p < 0.0001). The majority of the population studied sought care from public dental service and was from the middle class.
