Fintech and Web 3.0 represent two important constructs for an emerging web experience that is decentralized, social, and immersive. When integrating fintech solutions into digital projects, understanding market performance and impact from shocks can inform decisions around integrations as businesses and creators move towards Web 3.0 and emerging use cases that leverage NFTs, smart contracts, extended reality, and blockchain to deliver value. Additionally, fintech and Web 3.0 create new challenges for established firms where peer-to-peer value exchanges happen in real-time without the need for intermediaries and thus provide greater access to resources for disruptors, small enterprises, and creators. This proposal outlines a mixed methods research study that examines fintech performance and how it has responded to market shocks to answer the research question: What is the level of financial performance for fintech? The study is followed by an examination of how technology can power an immersive, decentralized digital experience that transcends borders and device platforms to answer the research question: What is the relationship between fintech and Web 3.0? The ability of fintech to increase banking inclusion and access to capital would be valuable as a facilitator of transactions between brands and peers (P2P) in a Web 3.0 ecosystem. Hence, understanding fintech performance and its relationship to a decentralized Web 3.0 will inform business leaders, creators, and researchers in identifying new use cases that combine both constructs building a more inclusive global value exchange ecosystem. While there is a growing body of knowledge on fintech, much less has been written about Web 3.0 and even less literature exists on the relationship between the two constructs. / Business Administration/Management Information Systems

In response to an invitation made by the researcher in a public school and a private school, six youths, four males and two females, with ages ranging from 10 to 15 years old, as well as their parents, volunteered to participate in the study. The criteria for participation in the study were: 1) The youth should be practicing less than 30 minutes of physical activity during most of weekdays, after school; 2) One of the parents be willing to participate, at any given moment of the research, for at least 30 daily minutes of physical activity with his/her child, and 3) Parent and child be able to meet with the researcher every three days, on average. The measurement of the physical activity involved a pedometer utilized by the youths throughout the week after school. The youths were instructed to complete a questionnaire daily, registering the type of physical activity performed, the time registered by the pedometer, the time spent in front of the screens, and parental participation in those activities. The participants were split into two groups in order to be submitted to the two sequences of conditions with the objective of evaluating a possible order effect. The results obtained during weekdays were analyzed separately from those obtained during weekends. All participants increased the amount of time spent on physical activity in relation to the Baseline, on both conditions of the research, independently of the order in which they occurred, and independently of the time spent in front of screens, which remained very high throughout the study. It was also observed that, except when the researcher gave special instructions, parental participation only occurred on weekends, generally facilitating their children s access to places where physical activities were most likely to occur. In the follow-up the levels of physical activity returned to basic levels for all participants / O objetivo da presente pesquisa foi verificar a influência dos pais em relação à prática de atividade física, quer desempenhando a função de um modelo que também se exercita, quer reforçando tal prática através de um sistema de fichas, trocáveis por pequenos brindes. Participaram do estudo seis jovens, quatro do sexo masculino e dois do sexo feminino com idades entre 10 e 15 anos e seus pais que se apresentaram como voluntários em resposta a um convite feito pelo pesquisador em uma escola particular e uma escola pública. Os critérios de inclusão no estudo foram: 1) o jovem praticar menos que 30 minutos de atividade física na maioria dos dias da semana, no período extra escola, 2) um dos pais se dispor a participar, em algum momento da pesquisa, por no mínimo 30 minutos diários de atividade física junto com o filho e 3) pai e filho terem disponibilidade para se reunir com o pesquisador, em média, a cada três dias. A mensuração da atividade física envolveu o uso de um pedômetro que foi usado, pelos jovens, todos os dias da semana no período extra escola. Os jovens foram instruídos a preencher um questionário diariamente no qual registravam o tipo de atividade física que praticavam, o tempo registrado pelo pedômetro, o tempo gasto diante de telas e a participação dos pais nessas atividades. Os participantes foram divididos em dois grupos de modo que fossem submetidos a diferentes sequências de condições com o objetivo de avaliar um possível efeito de ordem. Os resultados obtidos nos dias de semana foram analisados separadamente daqueles dos fins de semana. Para todos os participantes, houve aumento do tempo gasto em atividade física, em relação à Linha de Base, nas duas condições da pesquisa, independentemente da ordem em que ocorreram, sem relação com o tempo gasto diante de telas que se manteve muito alto no decorrer do estudo. Observou-se também que, exceto quando o pesquisador forneceu instruções específicas, a participação dos pais na atividade física de seus filhos ocorreu apenas nos fins de semana, geralmente, facilitando o acesso dos filhos a locais com maior probabilidade de ocorrerem atividades físicas. No Seguimento, os níveis de atividade física dos jovens retornaram aos níveis basais para todos os participantes

Classroom management is a common challenge in middle schools. Class-wide Function-Related Intervention Teams (CW-FIT) is a multi-tiered intervention designed to decrease problem behaviors at the classroom level (Wills et al., 2010). It is comprised of evidence-based practices such as teaching classroom expectations, increasing teacher praise, and using positive reinforcement in an interdependent group contingency. CW-FIT has shown promise in a variety of school settings, but it has not been tested in middle school art classrooms. This was initial investigation examining the effects of CW-FIT using a single-subject ABAB design in two middle school art classrooms. Results indicated that class on-task behavior increased by more than 25% and teacher praise-to-reprimand ratios more than doubled during CW-FIT implementation, compared to baseline levels. Results also indicated that on-task behavior for students identified as at-risk for emotional/behavioral disorders improved by more than 18% during the intervention. Teachers and students found the intervention to be socially valid. Results indicate promising implications for using CW-FIT in other middle school art classrooms.

Two male youngsters aged 10 and 11 years old and an adolescent girl aged 15 years old participated in the research, all of whom where above the desired weight and sought a non-profitable organization aimed at treating childhood obesity and their mothers. The researcher lent a movie camera to the participants and asked that P1 filmed lunch and dinner five times a week and asked that P2 and P3 filmed breakfast, lunch and dinner every day of the week. The videos were delivered weekly to the researcher, who categorized the adherence to the food orientation provided by the nutritionist from the non-profitable organization in three classes: total adherence, partial adherence and non-adherence. An independent observer categorized 20% of each participant s videos to calculate the agreement between the researchers. Initially, it was only taken observation and register of the adherence to the nutritional orientation for all the participants. Besides the video analysis, the researcher interviewed the participants three times a week, asking about the quality and quantity of the food and number of meals made on the day before. After the adherence to the nutritional orientation reached stability in lunch and dinner for P1, eventually reaching stability on the three filmed meals for P2 and P3, their mothers received instruction to give tokens to their children when they served themselves according to the nutritional orientation then exchanging the tokens for tangible items preferred by de youngsters. After P1 adhered to the nutritional orientation, his mother received instruction to give tokens for the adherence to the morning and afternoon snacks according to the Multiple Base Line design and to suspend the tokens in the lunch and dinner. P1 s mother suspended their participation in the study before it was possible to observe any weight loss. P2 and P3 were submitted to the Base Line and Reinforcement phase of the adherence to the nutritional orientation in breakfast, lunch and dinner. The results showed a better quality of food consumption for all participants after the token delivery for the adherence to the nutritional orientation. Despite that, P1 gained weight during the study, remaining in the obesity classification. P2 lost weight but not enough to abandon the obese classification. P3 was the participant who lost the largest amount of weight, reaching a normal weight for his age. The intra-subject applied also showed the necessity to create a individualized procedure, considering the idiosyncrasies of the participants. The data also showed the importance of the family, offering adequate food, avoiding excessive caloric food and with low nutritional quality and reinforcing healthy feeding behavior / O objetivo da presente pesquisa foi avaliar um programa de economia de fichas para modificar o comportamento de crianças obesas. Participaram do estudo dois jovens do sexo masculino com idades de 10 e 11 anos uma adolescente com 15 anos, todos apresentavam peso excessivo para a idade e freqüentavam uma ONG voltada para o tratamento da obesidade infantil e suas mães. A pesquisadora emprestou uma filmadora para os participantes e solicitou que P1 filmasse o almoço e o jantar cinco vezes por semana e P2 e P3 filmassem o café da manhã, almoço e jantar todos os dias da semana. Os filmes eram entregues semanalmente à pesquisadora que categorizava a adesão ao plano alimentar elaborado pela nutricionista da ONG em três classes: adesão total, adesão parcial ou não aderiu. Um observador independente categorizou 20% das filmagens de cada participante para calcular a concordância com a pesquisadora. Primeiramente, ocorreu apenas a observação e o registro da adesão ao plano alimentar para todos os participantes. Além de analisar os filmes, a pesquisadora entrevistava-os, três vezes por semana, questionando a respeito da qualidade e da quantidade de alimento e do número de refeições feitas no dia anterior. Depois que a adesão ao plano alimentar atingiu a estabilidade no almoço e no jantar para P1, vindo a atingir também a estabilidade nas três refeições filmadas para P2 e P3, as mães passaram a receber instrução para fornecer fichas para os filhos quando se serviam de acordo com o plano alimentar e depois trocá-las por itens preferidos pelos jovens. Após P1 passar a aderir ao plano alimentar, sua mãe recebeu instrução para fornecer-lhe fichas pela adesão aos lanches da manhã e da tarde segundo o delineamento de Linha de Base Múltipla e suspender o fornecimento de fichas no almoço e no jantar. A mãe de P1 interrompeu a participação no estudo antes que pudesse ter sido observada uma perda de peso dele. P2 e P3 foram submetidos apenas às fases de Linha de Base e Reforçamento da adesão ao plano alimentar no café, almoço e jantar. Os resultados mostraram que para todos os participantes houve melhora na qualidade da alimentação após o fornecimento de fichas para a adesão ao plano alimentar. Apesar disso, P1 ganhou peso durante o estudo, mantendo-se dentro da classificação de obesidade. P2 perdeu peso, porém não o suficiente para deixar de ser considerada obesa. P3 foi o participante que mais perdeu peso, atingindo um peso considerado normal para a sua idade. O delineamento intrasujeito empregado evidenciou a necessidade de criar um procedimento individualizado, considerando as idiossincrasias dos participantes. Os dados também apontaram a importância da família, disponibilizando alimentos adequados, evitando alimentos excessivamente calóricos e com baixa qualidade nutricional e reforçando os comportamentos alimentares saudáveis

The token economy is a widely used and versatile motivational system within applied behavior analysis. Moreover, token reinforcement procedures have been shown to be highly effective in the treatment of children with autism spectrum disorder (ASD). In the experimental analysis of behavior, token reinforcement contingencies are conceptualized as three interconnected schedule components: (1) the token-production schedule, (2) the exchange-production schedule, and (3) the token-exchange schedule. Basic work with nonhuman subjects has demonstrated that the exchange-production schedule is the primary driver of performance in these arrangements, and that variable-ratio exchange-production results in reduced pre-ratio pausing and greater overall rates of responding relative to fixed-ratio exchange-production schedules. However, little applied research has been conducted to assess the generality of these findings within applied settings. The purpose of this study was to determine if fixed- and variable-ratio token exchange-production schedules would exert differential effects on pre-ratio pausing and overall rates of responding for three children with ASD during a free-operant sorting task. The results showed that pre-ratio pausing and overall rates of responding were not differentially effected by the fixed- and variable-ratio exchange-production schedules. Discrepancies between the experimental work and the current study are discussed along with additional limitations.

Feedback is discussed in many disciplines. In behavior analysis, it has been discussed in terms of its functions, many coming to different conclusions. The present study evaluated whether therapists' preferred temporal and format of feedback shifted or changed during acquisition or maintenance of skills implementing a tact program using a token economy system after a brief exposure to all possible feedback combinations. Three participants completed a questionnaire before they were exposed to a feedback sampling phase and preferred feedback phase. Preferred way of recieving feedback was asked at the beginning of each session. Two out of three participants switched preferences after achieving mastery of task. Task mastery may make feedback delivered at the end of a session more desirable while task acquisition may make feedback delivered at the end of a trial more valuable. Limitations and future research were discussed.
