A Snapchat Marketing Perspective: Examining the Personality Traits and Motives that Predict Attitudes Toward and Engagement with Non-Sponsored and Sponsored Content in Snapchat.

Social networking sites (SNS) have revolutionized the communication between consumers and brands, publishers, and marketers. These platforms have become a way for advertisers to communicate directly and engage users with content that is innovative and less intrusive. The aim of this research is to examine the personality traits and motives (based on the uses and gratifications theory) that predict attitudes toward and engagement with non-sponsored and sponsored content in Snapchat. An online survey with 606 participants showed that the main motives of using Snapchat were social information seeking, entertainment, and impression management. Multiple regression analyses were used to determine what personality traits predict the motives for using Snapchat. Finally, hierarchical multiple regressions were used to examine the models that predict attitudes toward the non-sponsored and sponsored features in Snapchat as well as the engagement with them. Recommendations for practitioners were given to help them develop marketing strategies in Snapchat

Acolhimento institucional: alternativas e desafios para os (des)acolhidos.

TCC (Graduação) - Universidade Federal de Santa Catarina. Centro Socioeconômico. Serviço Social.O presente estudo refere-se à problematização sobre o processo de desligamento dos adolescentes em uma Instituição de Acolhimento. A saída da instituição é um momento de descobertas, onde o novo não é apenas o que está além dos muros, mas também o que surge no interior de cada indivíduo. Esta fase provoca medos e, ao mesmo tempo, gera expectativas. Assim, faz-se necessário preparar a criança e o adolescente para o desligamento desde à sua chegada na instituição. Neste sentido, a pesquisa voltou-se para a percepção dos sujeitos sobre as ações desenvolvidas no processo de desligamento institucional dos adolescentes ao atingirem a maioridade, tendo como objetivo geral: analisar a perspectiva dos adolescentes sobre o processo de desligamento de um serviço de acolhimento institucional. Os objetivos específicos foram: identificar o processo de desligamento dos adolescentes no serviço de acolhimento com ênfase na percepção dos sujeitos (Des)Acolhidos; Conhecer a dinâmica de vida dos adolescentes dentro do espaço Institucional; Caracterizar o processo de preparação para o desligamento institucional; Possibilitar aos adolescentes a expressão de seus anseios e perspectivas de futuro. Quanto à metodologia da pesquisa pautou-se na abordagem qualitativa, por meio da análise de informações de aspectos subjetivos e objetivos, utilizandose a técnica de entrevista semiestruturada com aplicação de questionário como instrumento de coleta de dados. A entrevista foi realizada com três adolescentes: Rita e Maria e Caetano (nomes fictícios) em processo de desligamento numa Instituição de Acolhimento no Município de Florianópolis- SC. Os resultados se deram em duas ordens: quanto à equipe, evidencia-se a necessidade de investir constantemente em práticas formativas que para esteja preparada a realizar um desligamento que atenda às necessidades psicossociais destes. Também se destaca a necessidade de ampliação do quadro de profissionais, bem como o fomento da atuação interdisciplinar e intersetorial para garantir o acesso dos adolescentes a bens e serviços que vislumbrem sua autonomia, bem como seu amparo no período pósdesligamento. No que se refere aos adolescentes, observa-se que todos os entrevistados relataram boa acolhida pelos profissionais na instituição. Destacaram confiança, diálogo, bons vínculos e tratamento igualitário dentro do espaço institucional. No entanto, podem-se perceber, em suas falas, lacunas institucionais e ausências de esclarecimentos no momento da acolhida. Por isso, é importante destacar a necessidade de um acolhimento em que a criança seja ouvida e que seja capaz de compreender o que está acontecendo de maneira a construir o processo de aceitação da realidade vivida. Quanto ao processo de desligamento da instituição, a maioria das falas demonstra sentimentos contraditórios de incerteza, felicidade, angústia, desamparo.Nota-se que os entrevistados compreendem que a saída da instituição implica em todas as responsabilidades que essa independência acarretará. Por isso,é importante estimular e garantir o acesso dos adolescentes aos cursos profissionalizantes e programas formativos como “jovem-aprendiz”. Para isso, é salutar que acorra uma articulação intersetorial, para que possam ter acesso a bens e serviços que possibilitem sua autonomia digna. Por fim, espera-se que este trabalho, de alguma forma, possa contribuir com o Serviço Social e equipes interdisciplinares que atuam junto a este segmento.This study refers to the problematization of the process of adolescent dismissal in a Welcoming Institution. The exit of the institution is a moment of discovery, where the new is not only what is beyond the walls, but also what arises within each individual. This phase causes fears and at the same time generates expectations. Thus, it is necessary to prepare the child and the adolescent for the shutdown since their arrival in the institution. In this sense, the research turned to the perception of the subjects and the actions developed in the process of institutional disconnection of adolescents when they reached adulthood, with the general objective: analyze adolescents' perspective on the process of disconnection from an institutional care service. The specific objectives were: to identify the process of detachment of adolescents in the host service with emphasis on the perception of the (host) subjects; To know the dynamics of life of adolescents within the Institutional space; To characterize the process of preparation for institutional disengagement; To enable adolescents to express their aspirations and perspectives for the future. The methodology of the research was based on the qualitative approach, through the analysis of information on subjective and objective aspects, using the semi-structured interview technique with the application of a questionnaire as an instrument for data collection. The interview was conducted with three adolescents: Rita and Maria and Caetano (fictitious names) in the process of being disconnected from a Welcoming Institution in the city of Florianópolis-SC. The results were given in two orders: regarding the team, it is evident the need to invest constantly in training practices that are prepared to perform a shutdown that meets the psychosocial needs of these. It also highlights the need to expand the professional staff, as well as the promotion of interdisciplinary and intersectoral actions to ensure access for adolescents to goods and services that glimpse their autonomy, as well as their support in the post-retirement period. Regarding adolescents, it is observed that all interviewees reported good reception by the professionals of the institution. They highlighted trust, dialogue, good ties and equal treatment within the institutional space. However, one can notice, in his speeches, institutional gaps and absence of clarifications at the time of the reception. Therefore, it is important to highlight the need for a welcome in which the child is heard and able to understand what is happening in order to build the process of accepting the lived reality. As for the process of detachment from the institution, most of the speeches show contradictory feelings of uncertainty, happiness, anguish, helplessness. It is noted that the interviewees understand that leaving the institution implies in all the responsibilities that this independence will entail. Therefore, it is important to encourage and guarantee access for adolescents to vocational courses and training programs as "young apprentice". For this, it is salutary that there is an intersectoral articulation, so that they can have access to goods and services that enable their dignified autonomy. Finally, it is hoped that this work, in some way, can contribute to the Social Service and interdisciplinary teams that work together in this segment

Physical, chemical and mineralogical characterization of a Brucutu iron ore sample.

A caracteriza??o de um min?rio permite a previsibilidade do seu comportamento frente aos processos de concentra??o. Apenas dados granuloqu?micos nem sempre s?o suficientes, sendo o reconhecimento das esp?cies minerais, suas propor??es, forma de gr?os e liberabilidade tamb?m fundamentais. Neste trabalho ? apresentada a caracteriza??o f?sica, qu?mica e mineral?gica de um min?rio de ferro da mina de Brucutu/Quadril?tero Ferr?fero-MG. Foram realizadas an?lises granulom?tricas por peneiramento e granul?metro a laser, qu?micas por fluoresc?ncia de raios X e mineral?gica por microscopia ?ptica e difra??o de raios X. Baseado nos resultados obtidos, o min?rio foi classificado como fri?vel, com teor global de Fe igual a 42,9% e SiO2 de 36,1%. Os minerais de ferro identificados foram hematita e goethita e, o principal mineral de ganga o quartzo. Na fra??o +1,0 mm o quartzo ocorre majoritariamente em part?culas mistas com os gr?os de hematita e goethita. Abaixo desta granulometria, o mesmo ocorre como part?culas livres. Acima de 0,15 mm a hematita ? predominantemente porosa, e abaixo de 0,15 mm granular. A goethita encontra-se associada ? hematita granular em todas as fra??es granulom?tricas.The characterization of an ore allows the predictability of its behavior in relation to the concentration methods. Only size and chemical analyses are not always sufficient, and the recognition of mineral species, their proportions, grain form, and liberability are also fundamental. In this work the physical, chemical and mineralogical characteristics of an iron ore from Brucutu mine in Quadril?tero Ferr?fero is presented. Particle size analyses were carried out by sieve and laser granulometer, chemistry by X-ray fluorescence and mineralogical by optical microscopy and X-ray diffraction. Based on the results obtained, the ore was classified as friable, with an overall Fe content of 42.9% and SiO2 of 36.1%. The iron minerals identified were hematite and goethite, and the main gangue mineral was quartz. In the fraction +1.0 mm the quartz occurs mainly in mixed particles with the hematite and goethite grains. Below this size, the same occurs as free particles. Above 0.15 mm the hematite is predominantly porous, and below 0.15 mm granular. Goethite is associated with granular hematite in all size distribution

A flota??o ? um processo de concentra??o, usualmente, empregado no beneficiamento do min?rio de ferro. O presente trabalho teve como objetivo avaliar a influ?ncia de vari?veis no processo de flota??o em bancada utilizando a t?cnica de an?lise de componentes principais. Para isso, realizou-se uma an?lise estat?stica com o aux?lio do software R, onde foram estudados os teores de s?lica e ferro na alimenta??o, no concentrado e no rejeito, teores dos contaminantes na alimenta??o (lama, ?xido de c?lcio e ?xido de magn?sio), perda por calcina??o e dosagem de amina. Por meio da an?lise foi poss?vel concluir que as duas primeiras componentes explicaram juntas aproximadamente 45% da variabilidade total da matriz de dados. A primeira componente explicou em torno de 25% da vari?ncia, sendo relacionada com a perda de seletividade do processo de flota??o. J? a segunda componente explicou cerca de 20% da vari?ncia e descreveu a inefici?ncia do processo. Atrav?s dos estudos realizados, foi poss?vel observar que a t?cnica de an?lise de componentes principais pode ser utilizada para melhor entendimento das vari?veis dos processos de flota??o em bancada.Flotation is a process of concentration, usually, employed in iron ore processing. The present work aimed to evaluate the influence of variables in the flotation process in the bench-scale using the principal components analysis technique. For this purpose, a statistical analysis by using the software R was carried out, studying the silica and the iron contents in the feed, in the concentrate and in the tailings as well as the contaminants (mud, calcium oxide and magnesium oxide) in the feed and also the loss on ignition and amine dosing. The analysis has allowed to conclude that the first two components together account for approximately 45% of the total variability of the data matrix. The first component explained about 25% of the variance, related to the loss of selectivity of the flotation process. The second component explained about 20% of the variance and described the inefficiency of the process. The conducted studies have shown that the principal components analysis technique can be used to a better understanding of the variables of the bench-scale flotation processes

Programa de P?s-Gradua??o em Engenharia Mineral. Departamento de Engenharia de Minas, Escola de Minas, Universidade Federal de Ouro Preto.A produ??o de rejeitos provenientes do setor m?nero-metal?rgico ? um dos fatores de contamina??o ambiental e tem despertado a aten??o no sentido de seu reaproveitamento. Durante o processo de fabrica??o de ferro-ligas de mangan?s ? gerada grande quantidade de rejeitos inerentes ao processo, dentre estes, o lodo dos tanques de decanta??o que recebem os efluentes l?quidos. O processo de fabrica??o das pe?as artesanais de pedra-sab?o tamb?m gera uma grande quantidade de res?duos, como os finos, dispostos muitas vezes pr?ximo ?s oficinas sem nenhuma forma de controle. Este trabalho teve como objetivo caracterizar o lodo proveniente de tanques de decanta??o de uma usina de fabrica??o de ferro-ligas de mangan?s da regi?o de Ouro Preto - MG. Posteriormente, foram confeccionados e caracterizados corpos de prova cer?micos com substitui??o de parte da massa argilosa por lodo e avaliada a efici?ncia da incorpora??o na fabrica??o de cer?mica. Com a utiliza??o de t?cnicas de planejamento estat?stico de experimentos foram avaliadas se as vari?veis press?o de compacta??o (14 e 28MPa), substitui??o do solo por res?duo (5 e 10%) e temperatura de queima (850 e 1000oC) t?m influ?ncia nas propriedades de retra??o linear de secagem e queima, absor??o de ?gua, massa espec?fica aparente e resist?ncia ? compress?o dos corpos queimados. Como trabalhos anteriores com substitui??o somente por finos de pedra-sab?o demonstraram resultados satisfat?rios, realizou-se substitui??o do solo por lodo e esteatito em um mesmo corpo de prova, na melhor condi??o analisada, a fim de se obter uma resposta otimizada do processo. Baseado nas investiga??es foi poss?vel concluir que o lodo ? composto por quartzo, calcita, muscovita e caulinita, com presen?a de liga de mangan?s e esc?ria. Analisando os resultados com substitui??o do solo por lodo do tanque de decanta??o, observou-se que a melhor condi??o para fabrica??o de cer?mica seria com temperatura de queima de 1000oC, press?o de compacta??o de 28MPa e substitui??o de 5%. Em rela??o aos corpos de prova com substitui??o do solo por lodo e esteatito, percebeu-se que com a adi??o de esteatito ocorreu uma melhora nas propriedades de retra??o linear de secagem e queima e absor??o de ?gua. Os melhores resultados foram obtidos para os corpos de prova com substitui??o de solo por lodo e esteatito, com forma??o das novas fases cristalinas, espin?lio e enstatita, sendo que os par?metros analisados se apresentaram dentro do estabelecido para aplica??es tecnol?gicas. O res?duo do corpo de prova foi classificado como n?o perigoso e n?o inerte.The production of waste from the mining-metallurgical sector is one of the factors of environmental contamination and has aroused the attention of its reuse. In the production units of ferromanganese alloys are generated a large amount of waste, for example, the sludge formed in the settling tanks that receive the liquids effluents. The process of manufacturing the soapstone handmade pieces also generates a great amount of waste generated during the process, such as soapstone powder, that are normally discarded in inadequate places, without any form of control. The aim of this work was to characterize the sludge from settling tanks of a ferromanganese alloy manufacturing plant in Ouro Preto region. Subsequently, ceramic bricks were prepared and characterized with replacement of part of the clay mass by sludge and the efficiency of the incorporation in the ceramic production was evaluated. It was designed a factorial experimental design for the ceramics bricks prepared with composition of clay plus sludge to investigate whether the variables: replacement of soil for sludge (5 and 10%), compaction pressure (14 and 28MPa) and firing temperature (850 and 1000oC) had an influence on the responses (linear shrinkage, water absorption, firing specific weight and compressive strength). As previous work with replacement by soapstone powder showed satisfactory results, tests were carried out with replacement of part of the clay mass by sludge and steatite in the same brick, in the best condition analyzed, in order to obtain an optimized response of the process. Based on the investigations, it was possible to conclude that the sludge is composed of quartz, calcite, muscovite and kaolinite, with the presence of manganese alloy and slag. It can be seen that the best condition for ceramic production would be with a firing temperature of 1000oC, compaction pressure of 28MPa and 5% of replacement. In relation to the bricks with soil replacement by sludge and steatite, it was observed that with the addition of steatite an improvement in the linear shrinkage of drying and firing and water absorption properties. The best results were obtained for the bricks with soil replaced by sludge and steatite, with formation of the new crystalline phases, spinel and enstatite. The parameters analyzed were within the established for technological applications. The residue was classified as non-hazardous and not inert
