Tomada de decisões em sistemas financeiros utilizando algoritmos de aprendizado de máquina supervisionado / Decision making in financial systems using supervised machine learning algorithms

Otte Júnior, Luís Carlos 17 October 2018 (has links)
Embora existam soluções para sistemas de cobrança e telecomunicações que apresentem relatórios para auxílio à cobrança de clientes, ambas carecem de informações que apoiem a tomada de decisões, nas análises estratégicas e na propensão de pagamento. Desse modo, o objetivo deste projeto é implementar ferramentas e soluções inteligentes a fim de reduzir o desperdício de tempo e aumentar a produtividade do gestor, decorrentes da necessidade da análise e cruzamento de todos os dados para tomar qualquer ação durante os processos de cobrança e gestão de custos. / Although there are solutions for billing and telecommunications systems to present reports to support debt collection, both lack information to support decision making in strategic analysis and propensity to pay. Thus, the goal of this project is to implement intelligent tools and solutions taht are able to increase their productivity and reduce waste of managers time, due to the need of analyzing and crossing all the data to take action during the collection processes and cost management.

Lived Experiences of Six High School Graduates Who Received Assistance from Graduation Coach Facilitation

Gragg, Gayle A 01 May 2015 (has links)
The purpose of this study was to understand the obstacles faced as well as strategies used by 6 graduates of a small rural high school in Southern Middle Tennessee. Specifically, this study was an examination of the life experiences of 6 graduates, identifying the major obstacles faced and the successful strategies used to complete the requirements for a high school diploma. Qualitative methodology guided this study. This approach allowed for the lived experiences to be examined and the voices of 6 participants be heard. Data collected included participant stories using semistructured interviews conducted using an interview protocol, drawing of a concept map, and prioritization of influences according to their perspective regarding their diploma completion. Other valuable data included researcher field notes and graduation coach file notes. Findings are presented in 6 themes pertaining directly to the interview questions regarding key elements—circumstances leading to a relationship with a graduation coach, discussions during grad coach sessions, nongrad parent influences, parent expectations, grade retention, and strategies implemented by the graduation coach. After the collection and analysis of all data, the researcher coded the data to determine emerging themes. Much of the researcher’s work consisted of processing the data to discover categories and patterns among the stories told by the 6 graduate participants, as presented in the qualitative narrative analysis methodology. Through the narrative inquiry method of this study, the examination of the stories of 6 graduates reveals that a relationship with at least 1 caring adult in the high school setting is imperative to successful high school completion. This adult may offer assistance through a variety of ways such as developing an academic plan of action, building confidence, arranging tutoring sessions, or tracking progress.

Summer Credit Recovery and Middle Grade Students

Sharp, James C. 01 December 2013 (has links) (PDF)
The purpose of this study was to examine the difference in student success by retained students who participate in the Hamblen County (Tennessee) Credit Recovery Program [HCCRP] in the year prior and following their participation. HCCRP is an alternative intervention for students who have been retained in the middle grades of Hamblen County School System. Student success was defined and assessed in the areas of academic proficiency, discipline, and student absenteeism. Student information regarding each area was obtained from the Hamblen County School System, coded, and analyzed through quantitative testing. This study was guided by 8 research questions and 8 corresponding null hypotheses. Five of the null hypotheses were tested for significance using a paired sample t tests, 2 were tested using a chi square testing, and 1 was tested using a single sample t test. The population of this study was 94 students who had participated in the HCCRP in the 2010- 2012 school years. The analysis of data showed no significant difference in student science scores, number of discipline referrals, or absenteeism in comparing the year prior and the year following the students’ participation in HCCRP. The paired sample t test did reveal significant increases in both student math and reading/language arts scores. A chi squared test showed a significant number of low socioeconomic students within the population. Additionally, a single sample t test showed a significantly higher number of days students missed prior to attending HCCRP and the acceptable level of absenteeism. The result of this study indicates that students who have attended HCCRP as an alternative to grade level retention benefited academically in math and reading/language arts.

A Qualitative Analysis of African American Female High School Graduates' Perceptions of Participating in an Asynchronous Credit Recovery Program

Waters, Eric Leftwich January 2010 (has links)
Asynchronous online credit recovery programs have been implemented in public schools across the United States for a variety of reasons. In this case, African American female students who are deficient in course credits towards high school graduation have taken advantage of this relatively new e-programming mechanism as a means to capture course credits that were lost during the course of a student's high school career. Female enrollees in the asynchronous credit recovery program are lacking in course credits due to course failure for reasons such as truancy, excessive absences, maternity, incarceration, employment, health associated and domestic related demands outside of school. Beyond the aforementioned, the school climate in terms of organization, discipline, safety, and supportive relationships plays a significant role towards student success or failure. Because African American females are positioned at the bottom of the ethno-gender stratum, concentration on African American females is vital to ensuring academic success in addition to their well being. The purpose of this qualitative study is to investigate and ultimately understand the perceptions, attitudes, and behaviors of a group of African American female graduates while enrolled in an asynchronous credit recovery program. The study was guided by the following research questions: How does enrollment in an asynchronous credit recovery program affect non-traditional African American female's perceptions of education? How does enrollment in an asynchronous credit recovery program affect the lives of non-traditional African American female student participants? What are the factors that contribute to the success of the non-traditional African American female student participants? Data were collected through semi-structured interviews, intense site immersion and observation, and thorough review of school district and student records. At the culmination of the data collection process, data analysis was conducted using the constant comparison method. Results from the data analysis revealed a reinvigorated perception of education as well as a reversal of lowered expectations, behaviors, standards, and attitudes while enrolled in the asynchronous credit recovery program. Enrollment in the asynchronous credit recovery program assuredly fostered academic success and strengthened the independent nature and identity formation of the African American female participants. Several of the implications for practice are: strengthening adult/student relationships; culturally relevant professional development exercises; consideration of a female centered curriculum; address the at-risk student population as early as elementary school; and continuing research on the effectiveness of asynchronous credit recovery programs. / Educational Administration

The Impact of Online Credit Recovery Programs on the On Time Graduation Rate in Virginia School Divisions

Wyatt, Wendy Sue 02 June 2017 (has links)
The choice to drop out of high school often follows a progression of disengagement from school (Bridgeland, Dilulio, and Morison, 2006). Students often begin this process as a result of attendance challenges, disciplinary consequences, and persistent failure in traditional learning environments (Bridgeland et al., 2006; Fenning et al., 2012; Foley and Pang, 2006). School divisions face federal and state mandates to improve graduation rates and are under pressure to reform educational practices in an effort to lower the dropout rate (Picciano, Seaman, Shea, and Swan, 2012). School districts around the country have sought to diminish dropout rates through a variety of strategies. The collective goal in all of the initiatives is to redefine the high school experience for students who do not fit the traditional model, connecting them with alternative learning opportunities so as to best meet individual needs (Ferdig, 2010; Carver, Lewis, and Tice, 2010). Online credit recovery programs have the potential to re-connect students at risk of dropping out of high school through technological interactivity, personalization, and immediate feedback (Ferdig, 2010; Watson and Gemin, 2008). This study identified 97 Virginia school divisions offering online credit recovery programs to students identified as at-risk. This dissertation examined the relationship between the use of online credit recovery programs and on-time graduation rates in the Virginia and found an increase in the on-time graduation rates in the school divisions that implemented this strategy. The researcher also examined the various models used throughout the Commonwealth and found a variety of implementation strategies used by school divisions. However data indicated no significant difference in the Virginia on-time graduation rates when comparing the different program implementation measures. / Ed. D.

Returning student characteristics, reasons for reentry, and effective program practices in a selected Texas alternative education program

Wilkinson, Herlinda Aguilar, 1958- 11 March 2014 (has links)
The purpose of this research was to ascertain the characteristics of dropouts, their rationale for reentry, and what constituted effective practices within a Texas alternative education program (AEP). While, a number of studies have been conducted to explain why students drop out of school, more research was needed in the area of students that reenter to complete their studies (Fernandez, Paulsen & Hiranko-Nakanishi, 1996; Krashen, 1998; NCES, 1981; Pirog & Magee, 1997; Ramsey, 1988; Rumberger, 1995; Warren, 1996; White & Kaufman, 1997). The study utilized qualitative methodology with a case-study approach by utilizing small groups within the context of an organization (Miles and Huberman, 1994). The study site was purposely selected (Kuzel, 1992; Morse, 1989) using low-socio-economic criteria, ethnic representation, an AEIS rating of Commended, and a high graduation rate. Site participant selection included comprehensive sampling (Goetz and LeCompte, 1984) of the AEP personnel and random sampling of the student participants and their respective parents. The primary data was collected using a modified three-interview method (Dolbeare and Schuman, 1982) with corroborating document review and focus groups. Findings indicated that research participants could identify seventeen different characteristics for returning high school students. Some of the characteristics describing these students also reflect their motivation or rationale for returning back to complete their high school studies. The study revealed four major practices within the AEP that supported the program and its students towards their mission of graduating. These were: hiring the right personnel, monitoring academic progress, providing student support services, and maintaining a safe school climate. A resultant theme indicated that there was a need to promote a positive image of the value of the AEP. Since only ten participants and five students were included in the study, the findings can only be tentatively generalized. Finally, suggestions are made for AEP programs to be designed to entice students not only to return back to school, but to remain until their goal to graduate is realized. / text

The Effect of Parental Support and Selected Variables on the Effectiveness of a Credit Recovery Program as It Relates to Successful Completion of Graduation Credits

Headd, Andrew C 27 February 2017 (has links)
The recent interest in graduation rates (a phrase sometimes used interchangeably and incorrectly with attainment rates and completion rates) began with the Commission on the Future of Higher Education, also known as the Spellings Commissions, which called for “dramatic” changes in higher education to address the “persistent gap between the college attendance and graduation rates of low-income Americans and their more affluent peers” (Cook & Hartle, 2011, p. 1). As educators, we should strive to make sure that the students we serve receive a quality education, one that will prepare them to be college or career ready. In recent years, the national graduation rate does not ensure that educators are preparing their students for life after high school. This study analyzed the findings from a specific credit recovery and how, when implemented with a strong parental involvement, a credit recovery can have a positive impact on the graduation rate. From the administering of a student survey and parent interview/questionnaire, it was determined that parental involvement and student motivation have the greatest impact on student achievement for students who participate in credit recovery. When students have consistent access to Georgia Virtual School, then their motivation is the strongest. The findings in this study imply that parental support impacts the academic success of students. If parents said they were informed about the credit recovery procedures, this implies that there is a high level of communication between the school and home. Educational leaders should focus on areas or predictors within the family, society, or individual circumstances of the child, as well as in the academic surroundings and materials in order to meet the diverse needs of the students.
