title: INVESTIGATING ONLINE RESPONSE STRATEGIES FOR ADDRESSING NEGATIVE WORD OF MOUTH

description: ABSTRACT The digital age has transformed how brands communicate and interact with their customers. One consequence is that the effect of negative word of mouth on a brand’s reputation has intensified. This study investigates various response strategies employed to protect organizations’ reputations in the online environment. Accordingly, it collected data through two methods. First, 10 semi-structured interviews were conducted with brand managers to identify the strategies that they used to minimize negative word of mouth in social media. Second, the social media interventions of different brands under management by agencies were collected to complement the interviews, and determine whether any additional strategies could be identified. The results showed that, when negative word of mouth events occurred, companies preferred to either apologize, hide the original message, respond in private rather than in public, or simply ignore the negative comments from customers.

title: Inverse Design of Tapers by Bio-Inspired Algorithms

description: Abstract The efficiency of optical power transferred between two bidimensional waveguides, continuous waveguide and periodic subwavelength waveguide has been designed and optimized by using a taper composed by variable length segments (0.03 − 0.27 µm). Waveguides with variable width (270 − 330 nm) have been considered and the number of segments on the taper region has been varied from 10 to 15. The optimized taper was efficiently designed using bio-inspired algorithms based on the genetic algorithms and the artificial immune system. The power coupled has been computed using the frequency domain finite element method. The best solution is 20% shorter than previously existent tapers with coupling light efficiency above 90% over a broadband interval of frequencies and it exhibits high fabrication error tolerances.

title: Characterization of the Dielectric Properties of the Tommy Atkins Mango

description: Abstract This paper presents the characterization of dielectric properties (dielectric permittivity and dielectric loss factor) of Tommy Atkins mango (Mangifera indica L), a fruit produced in several regions of Brazil, of great economic importance. The fruits were characterized according to their maturation index, by probe method, and identified by the yellowish tone in their bark. The results allowed correlating the dielectric characteristics of the fruit with the physicochemical transformations that occurred in the maturation process of the mango Tommy. It was also verified a greater variation in the frequencies below 1 GHz, with the maturation indicated by the dielectric signature on the fifth day after the harvest. From these results, we can observe the use of electromagnetic materials and techniques in the solution and optimization of processes in agriculture can improve the quality of products consumed or suggesting best practices to the productive sector.

title: Human papillomavirus type 18 E5 oncoprotein cooperates with E6 and E7 in promoting cell viability and invasion and in modulating the cellular redox state

description: BACKGROUND High-risk human papillomaviruses (HR-HPVs) are the etiological agents of cervical cancer. Among them, types 16 and 18 are the most prevalent worldwide. The HPV genome encodes three oncoproteins (E5, E6, and E7) that possess a high transformation potential in culture cells when transduced simultaneously. In the present study, we analysed how these oncoproteins cooperate to boost key cancer cell features such as uncontrolled cell proliferation, invasion potential, and cellular redox state imbalance. Oxidative stress is known to contribute to the carcinogenic process, as reactive oxygen species (ROS) constitute a potentially harmful by-product of many cellular reactions, and an efficient clearance mechanism is therefore required. Cells infected with HR-HPVs can adapt to oxidative stress conditions by upregulating the formation of endogenous antioxidants such as catalase, glutathione (GSH), and peroxiredoxin (PRX). OBJECTIVES The primary aim of this work was to study how these oncoproteins cooperate to promote the development of certain cancer cell features such as uncontrolled cell proliferation, invasion potential, and oxidative stress that are known to aid in the carcinogenic process. METHODS To perform this study, we generated three different HaCaT cell lines using retroviral transduction that stably expressed combinations of HPV-18 oncogenes that included HaCaT E5-18, HaCaT E6/E7-18, and HaCaT E5/E6/E7-18. FINDINGS Our results revealed a statistically significant increment in cell viability as measured by MTT assay, cell proliferation, and invasion assays in the cell line containing the three viral oncogenes. Additionally, we observed that cells expressing HPV-18 E5/E6/E7 exhibited a decrease in catalase activity and a significant augmentation of GSH and PRX1 levels relative to those of E5, E6/E7, and HaCaT cells. MAIN CONCLUSIONS This study demonstrates for the first time that HPV-18 E5, E6, and E7 oncoproteins can cooperate to enhance malignant transformation.

title: Potential of parents and hybrids experimental of the yellow melon

description: ABSTRACT: Melon or muskmelon (Cucumis melo L.) is of considerable economic importance in Brazil. Nearly all the cultivars currently grown are hybrids. Heterosis has been used to advantage in the melon plant, and the use of uniform hybrids is one of the reasons for successful cultivation. The aim of the present study was to evaluate the agronomic potential of yellow melon lines and hybrids. An experiment was conducted in randomized blocks with three replications to evaluate 24 hybrids generated by crosses among three elite lines used as female parents (AF-01, AF-02, and AF-03) and eight lines used as male parents (LAM-01, LAM-02, LAM-03, LAM-04, LAM-05, LAM-06, LAM-07, and LAM-08). Yield and fruit quality traits were evaluated. Partial diallel analysis was carried out to estimate general combining ability and specific combining ability. Additive and non-additive effects were observed for the yield, mean fruit weight, and pulp thickness traits. The lines AF-02, LAM-02, and LAM-03 are the most promising as parents as they more frequently have favorable alleles. The most prominent hybrids in diallel analysis were AF-02 x LAM-02, AF-02 x LAM-03, AF-02 x LAM-04, and AF-03 x LAM-06.

title: Antibiotic and Art: an Innovative Approach in Medical Education

description: Abstract: Introduction: To stimulate the practice of critical thinking and creativity and considering the complexity associated with antibiotic learning, the Antimicrobial Artistic Sensitivity Test (TSaA) was created, which is an innovative activity in antimicrobial teaching that evaluates knowledge and clinical reasoning through artistic presentations. Since the second semester of 2014 (2014.2), TSaA has proven to be an integrative practice in antimicrobial teaching for fifth-semester medical students of the University of Fortaleza/CE (UNIFOR). The objectives of this study were to analyze TSaA as a methodology of antimicrobial teaching / learning and students’ satisfaction with this practice. Methods: Fifth-semester medical students were divided into eight groups, each one with twelve participants. Students were challenged to show their knowledge of one class of antimicrobial drug using art as the communication tool. Each group was assigned to work with a specific class of antibiotic, which was previously randomly selected. Two teachers simultaneously evaluated the presentation, using a specific form to carry out this evaluation. In the end of the activity, students were invited to answer a questionnaire, with objective and subjective questions, addressing their perceptions of the activity, the benefits on antibiotic learning and identified difficulties. Results: A total of 92 students participated in the study. The methodology used to carry out the TSaA activity was considered adequate by 82% of the participants. Staging performance and music were the most frequently chosen forms of presentation. The majority of the participants indicated TSaA as a valuable strategy to facilitate antimicrobial learning. The association between antibiotic study and art was considered an amusing way of content learning. According to students’ perception, this practice also stimulated teamwork. In the students’ opinion, there was indeed a greater content learning with this activity. Conclusion: The Antimicrobial Artistic Sensitivity Test facilitated antimicrobial learning, stimulating the creativity and critical/logical thinking of fifth-semester medical students.

title: Health Empathy Map: Creation of an Instrument for Empathy Development

description: Abstract: Introduction: Empathy is a multidimensional construct that requires the ability to perceive and understand the others’ perspectives, as well as feel their emotional state. It is an intellectual skill to be learned and represents one of the domains of emotional intelligence. The aim of this study was to create an instrument for the teaching and practice of empathy skills in medical education scenarios, called the “Health Empathy Map” (HEM). Method: This is a qualitative and descriptive study, aimed at developing the Health Empathy Map. The study had 3 phases: (1) Adaptation of the empathy map for medical education scenarios (2) Adequacy of the instrument content performed by teachers from the Outpatient Clinic of José do Rosário Vellano University, during teacher training (3) Assessment of content and feasibility of the instrument, first performed using the focal group technique and then by third-year medical students during outpatient clinic practice and in the tutorial group. Results: The adequacy of the instrument for medical education teaching scenarios was based on conceptual aspects of empathy: perspective-taking, emotional sharing and empathetic concern, as well as suggestions from the outpatient clinic teachers, focal group participants and medical students. All suggestions were debated and accepted, after a consensus that indicated advances and improvements of the instrument, in order to allow its use by students in health learning scenarios. Conclusion: The final version of the HEM was considered by participants of different phases of the study, as an educational instrument with great instructional potential, in terms of stimulating the development of empathy, with a broad use in medical education scenarios.

title: Economic analysis of the risk of replacing corn grains (Zea mays) with pearl millet grains (Pennisetum glaucum) in the diet of feedlot cattle

description: ABSTRACT: The goal of the present study was to assess the economic viability relating to the risk of replacing corn with pearl millet in diets with 80% concentration for feedlot cattle confined for 89 days. Replacement levels were: 0, 33, 66, and 100%. The risk was estimated using Monte Carlo simulation, Spearman’s rank correlation test between input variables, stochastic dominance, and analysis of sensitivity. The expected average values ± standard deviation for net present value (R$/animal) were ± 71.74 ± 283.32, 91.23 ± 285.18, 196.05 ± 273.79, and 223.80 ± 267.96 for diets containing 0, 33, 66, and 100% of pearl millet, respectively. The probability of ≥0 net present value was 63.4, 66.1, 78.4, and 82.4%, respectively. The net present values were statistically different (P&lt;0.05), and the higher levels dominated the lower values. The items that most influenced the net present values were, in descending order, prices of unfinished and finished cattle, initial and final weights, prices of concentrate and forage, concentrate and forage consumption. Based on the results of the simulation, diet of 100% pearl millet exhibited the best economic viability.
