Pesquisa em Sistemas de Informação no Brasil: 27 Anos sob uma Ótica Internacional

Compreendendo que conhecer o passado é importante para planejar o futuro, neste artigo buscamos resgatar a história de sistemas de informação no Brasil, tendo como marco inicial o ano de 1988, quando a área de administração da informação (ADI) surge pela primeira vez de forma independente em um dos principais congressos de administração do Brasil, o EnANPAD. Como marco final, o ano de 2014, que representa a comemoração dos 20 anos da AMCIS (Americas Conference on Information System), evento que é referência na área de ADI, e que incitou um chamado para um olhar sobre a história de ADI através da área Celebrating the 20th Anniversary of AMCIS: Examining IS History. Para analisar estes 27 anos brasileiros frente à comunidade internacional, foram classificados 1.335 artigos de ADI publicados nos eventos da ANPAD nas áreas da AMCIS, trazendo um olhar longitudinal ao período. Como resultados, identificou-se que a área de Gestão de Projetos apresenta a maior tendência de crescimento. Ainda, apresenta-se um panorama de evolução e estado atual das pesquisas em SI no Brasil, bem como principais autores, instituições e temáticas trabalhadas ao longo do tempo.

Student's perception of school bullying and its impact on academic performance: A longitudinal look.

Bullying among peers has immediate and long-term consequences, as it affects children's health-related quality of life. The aim was to examine the association between the frequency, type and dynamics of children's involvement in bullying situations and their academic performance over the school year. Longitudinal study conducted in 2015 in 9 to 12 year-olds in schools of Bahía Blanca, Argentina. Outcome measures: children's involvement in bullying situations, frequency of participation in bullying and academic performance. Bullying categories were obtained through the Preconceptions of Bullying and Intimidation Among Peers (PRECONCIMEI) questionnaire and academic performance as reflected by each child's school grades. The survey included 375 children, of which 22.1% (83/375) were repeatedly involved and 30.12% (113/375) were occasionally involved in bullying situations (20.27% [76/375] reported having participated by the year end but not at the beginning, and 9.85% [37/375] showed the opposite behavior). No statistically significant differences were found, regardless of the course subject analyzed. Grades were found to have improved by school year-end, in all groups assessed. No association was found between bullying and academic performance.

A Longitudinal Look at Habit Strength as a Measure of Success in Decreasing Prolonged Occupational Sitting: An Evidence-Based Public Health Initiative

Background: Sitting to perform desk-based work is considered to be a habit. To test this hypothesis, desk-based workers volunteered to be part of a yearlong pilot study utilising an e-health intervention designed to interrupt prolonged workplace sitting with movement breaks. Methods: Participants in a passive-prompt group had to engage with an e-health software programme on an hourly basis during work hours, while participants in an active-prompt group were allowed to postpone the prompt each hour. Daily adherence data and self-reported sitting habit strength were measured every 13 weeks for one year. A mixed design ANOVA was used to determine significant differences at the p < 0.05 level. Results: Passive-prompt participants reported significant improvements in reducing sitting habit strength over time, compared to active-prompt participants who actually reported increased sitting habit strength. Conclusions: This study provided preliminary evidence that changing desk-based workers’ sitting habits might be more difficult than previously estimated and that passive-based interventions could be one solution.

A Bibliometric Analysis of the Knowledge Exchange Patterns Between Major Technology and Innovation Management Journals (1999–2013)

This essay takes a longitudinal look at the knowledge flow patterns between major technology and innovation management (TIM) journals and the effect on their impact factors. We analyze the flow of 29,776 citations from 4171 articles published in the top six dedicated TIM journals between 1999 and 2013. Findings indicate one subset of journals becoming more firmly rooted in the TIM domain, while the others becoming increasingly insulated from it. JPIM displays peculiar knowledge flow patterns, suggesting a broadening of its knowledge base and impact. Our bibliometric analysis provides one of the most comprehensive and detailed year‐by‐year looks at the intradomain knowledge exchange patterns over a 15‐year period.

The attractive concept of simplicity in environmental impact assessment: Perceptions of outcomes in southeastern Brazil

Pressures are mounting for the simplification of environmental impact assessment (EIA). This phenomenon is drawing increasing scholarly attention, but studies have not gone far beyond speculating what could happen as a result of recently implemented or proposed regulatory changes. This paper takes a more longitudinal look at simplified EIAs. The main objective was to analyze the perceived outcomes of a number of simplified EIA processes, using Brazil as the empirical context. More specifically, this paper aimed at understanding: 1) how simplified EIAs have been conceptualized and implemented in southeastern Brazil; and 2) how developers and civil servants in that region perceive the outcomes of simplified EIAs. This study adopted a sequential mixed method research approach. Data was collected through literature reviews, 261 telephone-based interviews and 10 face-to-face interviews. Degrees of EIA simplification can vary significantly within and across jurisdictions. In any case, simplification is often framed as a win-win solution to EIA ineffectiveness, through which regulatory and procedural changes are made to ease the process, while, at the same time, maintaining or providing better environmental protection. This approach is more frequently applied to potentially low-impact processes. Chi-square tests of the data collected through telephone interviews in the Brazilian state of Minas Gerais indicated that developers tend to perceive EIA processes as difficult and slow regardless of how simplified it is. Most civil servants, who were directly involved in the implementation of simplified EIAs in state environmental agencies, argued that simplified EIAs are driven mostly by environmental agencies, as these institutions have long been unable to cope with an ever-increasing load of license applications. Policy outcomes of simplified EIAs in the territory are not sufficiently monitored by state agencies. Civil servants revealed concerns about the potential long term effects of EIA simplification on the ground, as they have had limited resources for audits and inspections.

Voter Turnout and Bureaucrats across Time: A Further Examination of the Bureau Voting Model in the United States

Due to questions concerning the historical application of the economic theory of voting to the bureau voting model, this study takes a longitudinal look at the relationship between government employment and voter turnout in the United States. Probit and OLS models are used to examine data from the American National Election Study covering sixteen elections from 1982 to 2012. Contrary to previous findings, government employment is not shown to have an effect on voter turnout. These results suggest that the bureau voting model may need to be refined if it is to be used in future studies.

Espacio-Escolar en los proyectos de la Unesco para América Latina

The article seeks to describe and analyze the School-Space produced in the Prelac (1980-2000), EPT / Prelac (2002-2017) and EPT (1990-2015) projects of Unesco-UN for Latin America. A technical refinement in the propositions of the projects is evidenced, orienting for a centralization of the actions and objects on a single world axis, perceived this in the longitudinal look. We present a discussion on the interstate system represented in Unesco-UN, to then account for the projects for the Latin American region, we discussed the School-Space proposed in the projects. Finally, some comments are posted. &nbsp

Provider-Offered Medicare Advantage Plans: Recent Growth And Care Quality.

Hospitals and health systems are increasingly offering their own insurance products, a type of consolidation known as "vertical integration." The relationship between plan-provider vertical integration and quality of care has not been examined extensively or over time. We created a new data set of all vertically integrated Medicare Advantage contracts operating in the period 2011-15 and tracked their characteristics and quality over time. While the percentage of vertically integrated contracts increased slightly between 2011 and 2015, the percentage of all Medicare Advantage enrollees in them declined from 24.4percent to 22.0percent. Vertically integrated contracts generally were of higher quality than other contracts, with the largest differences related to enrollee satisfaction. These findings provide the first detailed, longitudinal look at vertically integrated Medicare Advantage plan enrollment and quality.

Abstract P2-11-02: A longitudinal look at toxicity management within a platform trial: Lessons from the I-SPY 2 TRIAL

Abstract Background: I-SPY 2 is a multicenter, phase 2 trial using response-adaptive randomization within biomarker subtypes to evaluate a series of investigational agents or regimens when added to standard neoadjuvant therapy for women with high-risk stage II/III breast cancer - investigational agent (I) +paclitaxel (T) qwk, doxorubicin &amp; cyclophosphamide (AC) q2-3 wk x 4 vs. T+/-HP/AC (control arm(s)). Although the primary endpoint is pathologic complete response (pCR) at surgery, a key secondary aim is to evaluate the toxicity profiles of these investigational agents. Distinct aspects of safety monitoring in a platform trial, as well as the specificities of safety management in a potentially curative population make the experiences from I-SPY 2 valuable to the community. Methods: Inclusion and exclusion criteria are uniformly applied to all women in I-SPY 2. When a new investigational agent/regimen is planned for the trial, agent specific laboratory/hematologic limits or additional required tests are added, as needed. Eligibility criteria remain in the trial for its duration and apply to all investigational and control arms. Laboratory and adverse event data are collected and monitored in real time. The lead investigator of the investigational agent/regimen who chaperones a specific agent/regimen through the trial (“Agent Chaperone”), Medical Monitor, I-SPY 2 Agents Committee, CRO safety group, and an active DSMB that meets monthly oversee the management of toxicities within each investigational agent/regimen of the trial. Toxicity profiles for an investigational agent/regimen are compared to their relevant control. Safety analyses are intention to treat. Results: From March 2010-May 2016, eleven (11) investigational agents/regimens have opened (and 6 have completed evaluation) and 973 women have been randomized. These agents/regimens span a variety of mechanisms of action including targeted therapies such as small molecule inhibitors and antibodies, as well as immunotherapies. Additions to the trial's eligibility criteria have been made with new investigational arms. Adverse events of special interest have been monitored for each investigational arm and specific toxicities treated uniformly when applicable. A risk-based monitoring plan has been implemented that focuses on the collection and review of the trial's most critical data elements including serious adverse events and drug specific safety issues, allowing for a more efficient and focused effort. Safety issues have been quickly addressed and requirements updated, when needed, given the importance of limiting (or avoiding) long-term safety complications within this neoadjuvant patient population. Accrual to the trial has (been) maintained over time and the safety of trial participants has been well managed. Conclusion: A platform trial requires an evolving, and focused safety-monitoring process that adapts as new investigational agents are included. I-SPY 2's infrastructure and team science approach has created a system to manage patients across multiple arms with different risk profiles. These practices will support the safe evaluation of additional new combinations and regimens and serves as a guide for safety management within standing platform trials.

The meaningful identity: A longitudinal look at the interplay between identity and meaning in life in adolescence.

Identity formation in adolescence is closely linked to searching for and acquiring meaning in one's life. To date little is known about the manner in which these 2 constructs may be related in this developmental stage. In order to shed more light on their longitudinal links, we conducted a 3-wave longitudinal study, investigating how identity processes and meaning in life dimensions are interconnected across time, testing the moderating effects of gender and age. Participants were 1,062 adolescents (59.4% female), who filled in measures of identity and meaning in life at 3 measurement waves during 1 school year. Cross-lagged models highlighted positive reciprocal associations between (a) commitment processes and presence of meaning and (b) exploration processes and search for meaning. These results were not moderated by adolescents' gender or age. Strong identification with present commitments and reduced ruminative exploration helped adolescents in having a clear sense of meaning in their lives. We also highlighted the dual nature of search for meaning. This dimension was sustained by exploration in breadth and ruminative exploration, and it positively predicted all exploration processes. We clarified the potential for a strong sense of meaning to support identity commitments and that the process of seeking life meaning sustains identity exploration across time.

Assessing successive bilinguals in two languages: A longitudinal look at English-speaking children in France

This study examines longitudinal standardized test scores in both languages of a group of successive bilinguals with L1 English acquiring L2 French. Participants included 22 native English-speaking children living in France. French was evaluated using a standardized receptive vocabulary test, as well as tests of phonology and morphosyntax. English was evaluated using the Core Language Score subtests from the CELF-4-UK. The children varied in age (6;9–12;7) and length of exposure (0;11–3;9) to French and were tested twice at 12-month intervals. At T1, 7 children scored below norms in both languages, while only 3 did so at T2. Two out of these 3 were arguably not typically developing children. Length of exposure to French emerged as an important factor only at T1, when a number of children were in early stages of acquisition (≤18months of exposure). English scores varied by age and weekly use of English. In successive bilingual children, language performance on L2 standardized tests can be expected to be (well) below norms during the first 18 months of exposure. English scores revealed that weak L1 performance is part of typical development in this bilingual context, but that L1 retention is also a possibility. Learning outcomesThe reader will be able to: (1) describe challenges associated with language assessment of successive bilingual children, (2) describe the impact that age and length of exposure can have on language performance in bilinguals, and (3) understand how assessing successive bilinguals using monolingual norms can lead to underestimation of language abilities.

Data Analytics to Improve School Libraries

To improve programs, school librarians can analyze and apply data. Standards can help with the process, such as California’s model school library standards. To meet those standards, it is important to recognize and focus on variables to improve library programs. Data analytics can help librarians identify which data to collect, how to organize and analyze the data, and make informed recommendations for library improvement. Data analytics based on the California school library survey offer a predictive model for school library program effectiveness. Data analytics based on the American Association of School Librarians survey offers a longitudinal look at school library programs. A sample scenario that addresses one of the key variables provides the basis for employing data analytics to improve services.

Is Prepartying a Cause of Heavy Drinking and Consequences Rather Than Just a Correlate? A Longitudinal Look at the Relationship Between Prepartying, Alcohol Approval, and Subsequent Drinking and Consequences

ABSTRACTBackground: Prepartying, or drinking before an event where more alcohol may or may not be consumed, has been positioned in the literature as a behavior engaged in by heavy drinkers. However, recent findings suggest that prepartying may confer distinct risks, potentially causing students to become heavier drinkers over time. Objectives: The goals of this study were to disentangle the longitudinal relationships between prepartying, general and episodic alcohol consumption, and alcohol-related consequences by investigating (1) whether prepartying is associated with future consequences above and beyond current alcohol consumption habits and (2) whether augmentations in approval for alcohol and related increases in drinking mediate this relationship. Methods: One-hundred and ninety-five undergraduates completed online questionnaires at baseline, 6 months, and 12 months later. Results: Prepartying frequency was more strongly related to alcohol-related consequences one year later than was overall or episodic drinking. In addition, a path mediation model confirmed our hypothesis that this relationship is due to gradual increases in drinking which occur as a result of more approving attitudes toward alcohol brought on by exposure to prepartying. Conclusion/Importance: Findings suggest a new model for conceptualizing the relationship between prepartying, drinking, and consequences whereby students who get involved in prepartying may witness slow increases in their approval for alcohol use and, as a result, consumption. Importantly, results suggest that the increases in drinking displayed by prepartiers over the course of a year may account for the strong relationship between prepartying and later consequences. Prevention and intervention initiatives may benefit from directly targeting prepartying as a means of tempering risky alcohol use trajectories during one’s college tenure.

Psychological distress leads to reduced physical activity and fitness in children: the Australian longitudinal LOOK study.

Stress and depression can affect an individual's level of physical activity and fitness, which may place them at risk of developing cardiovascular disease. This study investigates the longitudinal effects of stress and depression on physical activity and cardiorespiratory fitness among youth. Six hundred and seventy-six children, initially aged 8years, from the LOOK study completed a modified version of the Children's Depression Inventory, the Children's Stress Questionnaire, and objective physical activity and cardiorespiratory fitness assessments on three occasions, every 4years. Depressive symptoms had a direct effect (longitudinal) on the cardiorespiratory fitness of girls, with a similar trend for boys. In cross-sectional analyses, a child who identified with more symptoms of depression and stress was likely to be less fit and less physically active, which in girls extended to less moderate-to-vigorous physical activity. Our findings, that both physical activity and fitness are impacted by depression and stress may contribute to strategies directed towards achieving enhanced physical activity and reductions in obesity.

Abstract P4-10-10: The City of Hope breast cancer survivorship study: A longitudinal look at symptoms

Abstract BACKGROUND: Breast cancer survivors report many symptoms post treatment. However, longitudinal data, including pre-treatment measures, are scarce making it difficult to accurately attribute symptoms, as patients experience many changes; hormonal fluctuation, chemotherapy, additive endocrine therapy. Therefore, we undertook this longitudinal study to distinguish the impact of these different treatments along the survivorship time course, starting with time at diagnosis. METHODS: Female, breast cancer survivors completed symptom questionnaires (Qx) pre-treatment (pre-tx), at 6-months follow-up (during-tx) and 12-months (post-tx) follow-up. Women rated symptoms in the past week as not at all, a little bit, somewhat, quite a bit, and very much. Symptoms included, hot flashes, vaginal discharge, vaginal itching, vaginal dryness, pain during intercourse, loss of interest in intercourse, weight gain, dizziness, vomiting diarrhea, headaches, abdominal bloating, breast sensitivity, mood swings, irritability, and joint pain. Additional measures included view of overall health, overall pain in the past month, and average fatigue in the past week. Chi-square tests were conducted across time points and stratified by menopausal status and type of treatment. Symptom changes from baseline, clustered by subject, were entered into a generalized estimating equation (GEE) models. RESULTS: Of the 237 breast cancer survivors (median pre-tx age: 53 years, range: 24-70), who completed the pre-tx Qx, 112 completed the 6-month Qx and 95 completed the 12-month Qx. Women reported an increase in hot flashes from pre-tx to 6-months (p&amp;lt;0.001) and pre-tx to 12-months (p=0.04), with a slight decrease from 6 to 12 months (p=0.19). An increase in vomiting was observed from pre-tx to 6-months (p=0.04). Women reported an increase in vaginal discharge from pre-tx to 12-months (p=0.04), and a decrease in average fatigue in the past week from pre-tx to 12-months (p=0.04). Both overall pain in the past month and joint pain in the past week increased from pre-tx to 6-months and then decreased below pre-tx levels at 12-months (p=0.03 and p=0.12, respectively). Changes in hot flashes, vaginal dryness, pain during intercourse and weight gain were only observed among premenopausal women, while changes in vaginal discharge were only observed among postmenopausal women. GEE modeling showed associations between the use of endocrine therapy and increased hot flashes (Odds Ratio [OR]: 2.60, 95% Confidence Interval [CI]: 1.97-3.42), vaginal discharge (1.38; 1.15-1.66), pain during intercourse (1.34; 1.05-1.72), weight gain (1.61; 1.22-2.12) and joint pain (1.90; 1.48-2.45). By 12-months, severity of all symptoms decreased, except for vaginal discharge. Associations were observed between the use of chemotherapy and decreased weight gain (OR: 0.66, 95% CI: 0.48-0.91) and decreased breast sensitivity (0.67; 0.49-0.93). CONCLUSIONS: Several symptoms thought to be related to treatment may actually be present at time of diagnosis and many treatment-related symptoms appear to decrease by 12-months. Severity appears to be modified by menopausal status and type of treatment. Our results give crucial insight for the development of effective symptom-based management and intervention along the treatment time course.

Are we there yet?: A longitudinal look at e-books through students’ eyes

ABSTRACTStarting in summer 2011, two librarians at Wesleyan University annually interviewed and directed usability studies with undergraduate students to determine how students interact with academic e-books. In 2014, the librarians used a campuswide quantitative survey to supplement these longitudinal qualitative findings. While students are increasingly using e-books as resources, their facility with them has not increased at the same rate. Students continue to encounter issues with interface designs as well as the ability to easily control and manipulate their own copies. These quantitative and qualitative findings have proven important in local collection development practices as well as library instruction initiatives.

The Effect of Racial and Ethnic Composition on Neighborhood Economic Change: A Multilevel and Longitudinal Look

This article examines the relationship between racial/ethnic composition and neighborhood economic change in a multilevel and longitudinal framework. I employ multilevel modeling to examine how neighborhood minority composition is associated with change in neighborhood relative economic status from 1970 to 2010 in the largest 100 metropolitan areas of the USA. In the multilevel framework, the empirical analysis shows that the shares of black and Hispanic residents are consistently negatively related to neighborhood economic gain even when metropolitan-level factors are taken into account. This study also finds that the negative effect of neighborhood minority composition on neighborhood economic gain is differentiated by deindustrialization and minority composition at the metropolitan level. In the longitudinal framework, the findings show that the negative effect of neighborhood minority composition on neighborhood economic gain has declined over time.

Toward a Usable Academic Library Web Site: A Case Study of Tried and Tested Usability Practices

Usability testing is an important element when designing useful, usable academic library Web sites. Since 2001, members of the Florida International University Libraries Web team have worked toward establishing a process that identifies user needs through usability testing. Starting with the libraries’ first Web site redesign project in 2001, the team has taken an active part in improving Web site user experience. After engaging in multiple redesign efforts, the Web team has developed a process that supports awareness of user experience through continual usability testing and feedback gathering. This article presents strategies and practices to measure Web site user experience, including classic usability testing methods (e.g., card sorting activities, focus groups, and task-based user testing), as well as the team's latest effort to assess Web site analytics and content to identify Web site usage patterns and areas of concern. A history of the Florida International University Libraries’ Web site redesign process is presented to illustrate lessons learned and best practices to facilitate future redesign and testing efforts. Taking a longitudinal look at usability testing at one institution, the study aims to inform the development of an effective strategy for user research and content management.
