title: App adoption and switching behavior: applying the extended tam in smartphone app usage

description: ABSTRACT The increasing use of mobile applications have been escalating with the increasing use of smartphones. In the present study, we examine (a) the adoption behavior of mobile apps using the extended TAM framework, and (b) whether adoption leads to subsequent use behavior and switching intentions. Based on data collected from two surveys in India we test the conceptual model of extended TAM and the effects of behavior on switching intentions using factor analysis and structural equation modeling. The major findings indicate a significant effect of most predictor variables on the perceived usefulness and perceived ease of use of apps. Further, we found a significant effect of behavioral intention on use behavior and subsequent switching intentions to apps from computers/laptops.

title: Evaluation of artificial monoradicular teeth used for endodontic training

description: Abstract Introduction It is a challenge of pre-clinical teaching in Endodontics to provide students with artificial teeth that reproduce the internal and external morphology of human teeth. Objective To compare the internal and external morphology of single-rooted artificial teeth with data from the literature on human teeth. Material and method The artificial teeth were donated from two companies: Fábrica de Sorrisos, company A, (n=20) and IM do Brasil Ltda, company B (n=20). Measurement of total tooth length, root, height, buccal-palatal and mesio-distal crown dimensions with digital caliper was performed. The morphological description of the roots, crown and pulp chamber was performed, the last one only after access. The topographic location of the main apical foramen was evaluated after canal exploration with a K #15 endodontic instrument until it visually reached the root apex. The data were arranged in a spreadsheet and statistical analysis was performed (ANOVA, followed by the Tukey post-test (α=5%)). Result Regarding the morphometric parameters, the upper canine sample from company B presented all variables within the standards described in the literature. Regarding internal and external morphology, the sample of upper lateral incisors from Company A was the only one to present all variables within the standards described in the literature. Regarding the foraminal topographic location, the teeth of Company A, as well as the lower canine of company B, showed a tendency to the distalized and centralized position, in line with the literature. Conclusion none of the artificial teeth studied showed total morphological and morphometric similarity with the control, differing in at least one of the variables, and a review of their models is indicated to the manufacturers.

title: Evaluation of the Residency Programs of the Federal University of Rio Grande do Sul from the residents’ view

description: Abstract Introduction The multi-professional residencies in the Health area started to improve after the Law n° 11.129 of 2005. They are a modality of Latu-sensu graduate education, with the purpose of training professionals to work in the National Unified Health System (SUS). Objective This study aimed to investigate the current situation, from a perspective of satisfaction with the training in Residency courses, with the residents of the Federal University of Rio Grande do Sul. Material and method It is a study with a mixed-methods approach. The quantitative section was conducted through the application of a questionnaire to all residents participating in the UFRGS Residency Programs in 2018. The qualitative part was conducted using the focus group technique. Result There were 81 participants in the quantitative component, and 14 residents of the Oral Health program participated in the focus groups. The quantitative results showed that residents received little or no guidance at the beginning of the program. The qualitative results showed questions that allow inferences about residents' dissatisfaction and lack of knowledge about the functioning of the Programs. Conclusion Residents recognize that there are still issues with program administration to be improved, and more especially, the recognition of the importance of the Residency Programs within the University.

title: Influence of photobiomodulation on pain perception during initial orthodontic tooth movement

description: Abstract Introduction Laser in low intensity (LLI) has been used to reduce the discomfort and pain that is triggered by the forces applied during orthodontic treatment. Objective To evaluate the effect of LLI application in the pain perception of periodontal ligament initial compression, during orthodontic tooth movement; and to compare the effect of this therapy between men and women. Material and method The sample consisted of 30 volunteers, who needed orthodontic band placement on mandibular first molars. After insertion of the elastic separators, LLI was applied to the mesial and distal apical region (wavelength 808nm, energy 2J, time 20s and fluency of 8.32J/cm2) and at three points on the root region (wavelength 808nm, energy 1J, time 10s and fluency of 4.16J/cm2) of the first molar (irradiated side) and compared to the contralateral first molar (non-irradiated side), in three time intervals: 0hs, 24hs and 48hs. Pain perception was evaluated by the Visual Analog Scale (VAS), at 0hs, 24hs and 48hs after insertion, with significance of 5%. Result The pain level was observed to be significantly lower (p&lt;0.05) on the irradiated side, irrespective of gender and time. Women presented a significantly higher pain level (p&lt;0.05) than men, irrespective of time and side. There were no significant differences between the time intervals (p&gt;0.05). Conclusion It was concluded that LLI reduced the perception of initial pain in patients in whom compression of the periodontal ligament was promoted by elastic separation, and that women had a greater perception of pain sensitivity in the time intervals studied.

title: EXPLORING THE FACTORS THAT HAVE IMPACT ON CONSUMERS’ TRUST IN MOBILE PAYMENT SYSTEMS IN AUSTRALIA

description: Abstract Trust plays a vital role in the adoption of a new payment system in so far as people need to trust that the prevailing currency, or in other words, money, is recognised by all stakeholders. With the evolution of the payment methods, shifting from paper-based to electronic-based, building consumer trust has become a vital element for the success of businesses involved in the mobile payment systems sector. In this context, the aim of this study was to delve deeper into the factors that have impact on consumers trust in mobile payment systems (MPS) in Australia. A quantitative approach through a questionnaire survey was conducted to measure the data collected. The data of 200 participants were gathered using SurveyMonkey and the Excel spreadsheets was imported into SPSS (Statistical Package for the Social Sciences) system, where the data were organised. Besides, this study adopted the Partial Least Square Structural Equation Modeling (PLS-SEM), where the data analysis took place. The findings of PLS-SEM analysis pointed out that behavioural factors and organisational factors have significant impact on consumers’ trust, and this, as a consequence, have influence on MPS adoption. On the other hand, this research found that the technological factors, governmental factors and personal factors have no significant impact on Australian consumers’ trust and this, as a result, has no influence on MPS adoption.

title: THE POLITICS OF DATA PORTALS IN INTER- AND TRANSDISCIPLINARY RESEARCH

description: Abstract In this paper, we argue that the ongoing processes of datafication and dataism are constraining initiatives to construct open data portals contributing to inter- and transdisciplinary research. The former overvalues quantitative data, whereas the latter reinforces the belief that ‘raw data’ is neutral and apolitical, ignoring how data is processed. Based on the case study of an open data portal being developed at an inter- and transdisciplinary research institute, we argue that datafication and dataism are highly problematic trends, because they marginalize qualitative data employed in critical, constructivist, and other interpretive methods, thereby limiting the possibility of complementing and extending each other. Nonetheless, we also maintain that these trends are not technologically determined but are modifiable, based on the design of data portals. Accordingly, we conclude by offering suggestions for constructing data portals, such as opening up the design process and democratizing standards.

title: FACTORS THAT INFLUENCE THE ADOPTION AND IMPLEMENTATION OF PUBLIC DIGITAL ACCOUNTING ACCORDING TO THE EVALUATION BY MANAGERS OF BRAZILIAN COMPANIES

description: ABSTRACT This study aims to identify the factors that influence the adoption and implementation of the Public Digital Accounting System (Sistema Público de Escrituração Digital, or SPED) according to the evaluation of managers of Brazilian companies, expressed in response to a survey, based on the criteria established by the TOE framework, considering technological, organizational and environmental dimensions. The results show that although other factors influence decisions about the adoption and implementation of the SPED, government requirement, as a component of the environmental dimension, is the main factor driving those decisions. This seems to result from the fact that the government is a major, if not the main, actor in the regulatory environment. We also identified big expectations of companies regarding the possibility of reducing the volume of ancillary tax obligations (record-keeping and reporting obligations). The ranking generated from the survey is a contribution to the improvement of strategies for implementation of e-government projects, both by governments and companies.

title: SOMOTE_EASY: AN ALGORITHM TO TREAT THE CLASSIFICATION ISSUE IN REAL DATABASES

description: ABSTRACT Most classification tools assume that data distribution be balanced or with similar costs, when not properly classified. Nevertheless, in practical terms, the existence of database where unbalanced classes occur is commonplace, such as in the diagnosis of diseases, in which the confirmed cases are usually rare when compared with a healthy population. Other examples are the detection of fraudulent calls and the detection of system intruders. In these cases, the improper classification of a minority class (for instance, to diagnose a person with cancer as healthy) may result in more serious consequences that incorrectly classify a majority class. Therefore, it is important to treat the database where unbalanced classes occur. This paper presents the SMOTE_Easy algorithm, which can classify data, even if there is a high level of unbalancing between different classes. In order to prove its efficiency, a comparison with the main algorithms to treat classification issues was made, where unbalanced data exist. This process was successful in nearly all tested databases

title: ECONOMIC RESILIENCE AND CROWDSOURCING PLATFORMS

description: ABSTRACT The increased interdependence and complexity of modern societies have increased the need to involve all members of a community into solving problems. In times of great uncertainty, when communities face threats of different kinds and magnitudes, the traditional top-down approach where government provides solely for community wellbeing is no longer plausible. Crowdsourcing has emerged as an effective means of empowering communities with the potential to engage individuals in innovation, self-organization activities, informal learning, mutual support, and political action that can all lead to resilience. However, there remains limited resource on the topic. In this paper, we outline the various forms of crowdsourcing, economic and community resilience, crowdsourcing and economic resilience, and a case study of the Nepal earthquake. his article presents an exploratory perspective on the link can be found between crowdsourcing and economic resilience. It introduces and describes a framework that can be used to study the impact of crowdsourcing initiatives for economic resilience by future research. An initial a set of indicators to be used to measure the change in the level of resilience is presented.

title: CRITICAL FACTORS IN THE IMPLEMENTATION PROCESS OF INTEGRATED MANAGEMENT SYSTEMS

description: This study is the result of research whose purpose was to study the implementation process of integrated management systems, called ERP Enterprise Resource Planning in the business environment. This study, more specifically, tried to identify the variables in this process and that, somehow, made it easy or caused some type of difficulty implementing the system. Based on the mixed method approach (Creswell, 2003), the study was performed by means of the content analysis of technical and scientific publications about this theme and by means of a field research for data collection from primary sources. The content analysis was based on the per mile procedure by Bardin (1977), making it possible to identify critical factors that may be found in the implementation of ERP system projects. Primary data was collected from structured interviews with the managers in charge of the implementation of the system, in each of the 12 companies in different sectors of the economy and based in Brazil. Based on this information, it was possible to test the factors extracted from the content analysis and then develop a list of factors that may effectively influence the implementation process of the system. In order to recognize the possible relations between the selected factors, the Spearman (rsp) correlation coefficient was applied and the multiple regression analysis was performed by means of the stepwise procedure. The purpose of the regression analysis was to determine the relation of the “Assessment of the Implementation” dependent variable with other dependent variables in the selected categories. The results of these analyses showed that the support of the top management, the communication process for the clear evidence of this support, the technical support of the ERP program provider together with the project team expertise, training and qualification processes of the team in the system operation are significantly correlated and relevant factors for a successful implementation of the project.

title: Technological innovation projects: proposal for an integrative model between project management and knowledge management in a customer-supplier perspective

description: In face of strong competition, companies in Brazil have increased their financial investments in automation, offering new products and services and reducing operating costs. These companies are focusing their efforts on core competencies and, therefore, they often lack the internal expertise to implement new projects, especially those that bring technological innovation. For this reason, we use the processes of outsourcing or subcontracting to help implement such projects. The unit of analysis in this study is the project and the object of the study to analyze the process of knowledge transfer from a provider to a customer during the duration of the project, which involves new technologies. The main motivation of this work is to address the acquisition and retention of new knowledge related to projects designed for business customers. We have developed a study of three cases of multiple financial firms that buy new technologies and two suppliers of information technology. As a practical result, a management model of knowledge transfer and retention of knowledge in client companies is proposed and incorporated into project management.

title: Information technology governance in public organizations: how perceived effectiveness relates to three classical mechanisms

description: Information technology (IT) governance has received a lot of attention lately, with a growing strategic importance currently being given to IT by both public and private organizations. This justifies the existence of a body of scientific literature on IT governance, to which this paper belongs and makes an attempt to contribute to. Towards that end, an empirical study was performed involving 57 public organizations of the Brazilian federal administration, examining the relationship between three governance mechanisms – IT steering committee, IT solution manager, and IT investment portfolio management process and IT governance effectiveness. Based on the literature review, a conceptual model was developed to express the causal relations that these constructs were expected to hold with one another. Through a custom-designed questionnaire submitted to over 180 federal public employees, the causal model was tested using mediation analysis and mostly confirmed. Results indicate that Portfolio Management should always be taken into account for analyses that aim to evaluate the effects of IT steering committees and solution managers on IT governance effectiveness. This means that a nonexistent or an underperforming Portfolio Management Process can lead to a reduction or cancellation of the potential positive contributions of the other two mechanisms to IT governance. By informing decision makers and public managers at some of the main federal public organizations in the country on how to plan and deploy IT to promote a more effective governance, the conclusions presented herein fill a previous knowledge gap in the complementarity and the joint effectiveness of three IT governance mechanisms on the IT dynamics of key public organizations.

title: WHAT INFLUENCES INFORMATION SECURITY BEHAVIOR? A STUDY WITH BRAZILIAN USERS

description: ABSTRACT The popularization of software to mitigate Information Security threats can produce an exaggerated notion about its full effectiveness in the elimination of any threat. This situation can result reckless users behavior, increasing vulnerability. Based on behavioral theories, a theoretical model and hypotheses were developed to understand the extent to which human perception of threat, control and disgruntlement can induce responsible behavior. A self-administered questionnaire was created and validated. The data were collected in Brazil, and complementary results regarding similar studies conducted in USA were found. The results show that there is an influence of information security orientations provided by organizations in the perception about severity of the threat. The relationship between threat, effort, control and disgruntlement, and the responsible behavior towards information security was verified through linear regression. The results also point out the significant influence of the analyzed construct on Safe Behavior. The contributions involve relatively new concepts in the field and a new research instrument as well. For the practitioners, this study highlights the importance of Perceived Severity and Perceived Susceptibility in the formulation of the content of Information Security awareness guidelines within organizations. Moreover, users' disgruntlement with the organization, colleagues or superiors is a factor to be considered in the awareness programs.

title: State of the art: integrating services for mega events

description: This paper describes the state of the art of a simplified model for integration of services in mega events. The project context, which was financed by the National Research Council – CNPq, is divided into six major areas or functional groups: Urban Mobility, Tourism, Airports, Security, Energy and Telecommunications. The proposal is described in layers, as an infrastructure model of integration and services evaluation, describing its main layers and interaction processes. The proposal described in this paper is restricted to the telecommunication subproject; however, in the modeling of the scenario for the study case, it was necessary to consider requirements and variables that are common to all subprojects. In the specification process of these requirements, we noticed important processes that interact with some sectors in the city of São Paulo; however, in the mean time, we noticed some failures regarding the integration and collaboration performed by administrative elements of stadiums as a main focus in the mega event and part of our case study. Currently, the proposal is in its first version as open software for the evaluation of the services quality and the mega event infrastructure through the use of performance indicators.
