De forma crescente, uma das estratégias que as empresas estão descobrindo para melhor aproveitá-lo se traduz na construção de programas de marketing boca-a-boca, que nada mais é do que a gestão de recomendações provocadas pela organização, via incentivo a um grupo de participantes. Essas iniciativas suscitam novas abordagens e questionamentos, considerando possíveis problemas éticos sobre a credibilidade deste tipo de recomendação, bem como trazendo o foco dos estudos sobre boca-a-boca para seu receptor, ao contrário do extenso corpo de pesquisa sobre seus antecedentes. Para tentar preencher estas lacunas de conhecimento do que faz alguém aceitar uma recomendação e qual o impacto dela fazer parte de um programa incentivado de marketing boca-a-boca é que esta tese se apresenta. Objetivando conhecer e mensurar as fontes de influência para a aceitação de uma recomendação boca-a-boca, este estudo, após revisão de pesquisas sobre o tema, propôs um modelo capaz de relacionar e mensurar o impacto de um conjunto de elementos influenciadores para a aceitação de uma recomendação, bem como o efeito específico da participação em programa incentivado de marketing boca-a-boca. Após investigação qualitativa, com 12 entrevistas em profundidade para compreensão e refinamento dos elementos, uma survey foi aplicada a 350 participantes, público em geral. O instrumento de coleta de dados aplicado continha uma abordagem retrospectiva - inquirindo sobre recomendações passadas recebidas - e uma apresentação de cenário hipotético - inquirindo sobre a participação da recomendação em programa incentivado de marketing boca-a-boca. Como resultados do modelo, destaca-se a expertise de quem recomenda, bem como a similaridade que este possui com quem recebe a recomendação, os elementos mais relacionados à mensagem recomendada e sua consequente predisposição a aceitá-la. Ainda, foi possível identificar que o incentivo não anula a predisposição de aceitação da recomendação, no entanto, provoca sua redução, sugerindo cautela em sua utilização. Outros resultados do estudo ainda foram discutidos, bem como suas implicações para a academia e comunidade empresarial. / Considered over the last decades as a sociological phenomenon, word-of-mouth (WOM) has been used as a marketing tool for information diffusion, persuasion and customer winning. One of the growing company strategies due to these activities are the word-of-mouth marketing programs, which offer a group of current customers incentives to talk positively about their products/services to others. Such initiatives raise new approaches and concerns, considering possible ethical dilemmas about WOM credibility and also changing its focus from WOM givers to those who receive it. Hence, this dissertation is presented in order to fulfill the knowledge gaps of what makes someone accept a WOM recommendation and the impact of it coming from a company organized marketing program. Aiming to identify and measure sources of influence for WOM recommendation acceptance, the present study proposes, after literature review, a relational model able to correlate and measure the impact of a group of elements on WOM acceptance willingness as well as the particular effect of it being part of a company designed marketing campaign. So as to identify new and refine theoretical elements, a qualitative inquiry of 12 in-depth interviews was held which results conveyed input to a survey applied to 350 interviewees. Data collection questionnaire presented a retrospective design – inquiring about past received recommendations – and also a hypothetical scenario presentation – implying the recommendation being part of a company designed marketing program. Main model results indicate provider’s expertise as well as its similarity with receiver most related elements to WOM message and its resultant acceptance willingness. Still, findings could show company incentive does not annul recommendation acceptance willingness, however causes its reduction, suggesting caution on its usage. More detailed findings were discussed in the study, as well as its implications to academy and business community.

No presente trabalho serão apresentadas as diretrizes e os testes necessários para a implantação de um programa de controle de qualidade para o Eclipse 7.3.10 da Varian no Hospital das Clínicas da Faculdade de Medicina da USP, de acordo com a mais recente publicação da AIEA o TRS 430. Os testes recomendados pelo TRS 430 são basicamente divididos em testes de aceitação, comissionamento (testes dosimétricos e não dosimétricos), e testes rotineiros. O documento da AIEA está sendo implementado para o Eclipse no HC para os feixes de fótons de dois aceleradores lineares da Varian, Clinac 600C e Clinac 2100C. Os testes de aceitação verificaram parâmetros de \"hardware\"; integração do sistema \"network\"; transferência de dados, e \"softwares\". Os resultados obtidos mostraram boa concordância com as especificações do fabricante. Para os testes dosimétricos de comissionamento, foram realizadas medidas de dose absoluta para diversos arranjos experimentais. Esses valores foram comparados com os valores de dose gerados pelo SPTC. A grande maioria dos testes apresentou cerca de 90% a 80% dos pontos comparados, dentro dos níveis de tolerância, ou seja, uma boa concordância entre os valores experimentais e os valores gerados pelo SPTC. Somente arranjos de campos assimétricos apresentaram discordâncias grosseiras, mostrando a necessidade de uma investigação mais apurada para esses casos. Os testes de comissionamento não dosimétricos também apresentaram resultados excelentes, com praticamente todas as ferramentas e desempenho geral do sistema de acordo com as recomendações estipuladas no TRS 430. Foram aplicados também critérios de aceitabilidade para a comparação entre os valores de UMs gerados pelo sistema e os valores de UMs calculados manualmente. Os feixes no Eclipse foram caracterizados com dados transferidos do CadPlan e com dados provenientes do recomissionamento dos aceleradores, assim sendo, para esses testes encontrou- se uma diferença de até 3% para campos conformacionados para os dados de feixe provenientes do recomissionamento dos aceleradores, e de até 4% para os dados de feixe transferidos do CadPlan, sendo que o nível de tolerância estabelecido pelo TRS 430 para o arranjo era de 3%. / This work presents the guidelines and necessary tests tom implement a quality assurance program for Eclipse 7.3.10 from Varian at Hospital das Clinicas, Sao Paulo University School of Medicine - Brazil, in accordance with the new IAEA publication TRS 430. The recommended tests for the TRS 430 air mainly classified into acceptance tests, commissioning (dosimetric and non-dosimetric tests), and routine tests. The IAEA document\'s recommendations are being implemented at the hospital for two Varian linear accelerators - Clinac 600C e Clinac 2100C. The acceptance tests verified \'hardware\', integration of network systems, data transfer and \'software\' parameters. The results obtained are in a good agreement with the manufacturer\'s specifications. Measurements of absolute dose in several set-ups were made for the commissioning dosimetric tests. These data were compared to the absolute doses determined by the TPS. The great majority of the tests showed 90% to 80% of the analyzed data in acceptance levels, with a good agreement between the experimental data and the data determined by the TPS. Only settings with asymmetric fields presented significant discords, showing the need for a more detailed inquiry for these settings. The non-dosimetric commissioning tests have also presented excellent results, with virtually all the system tools and general performance in compliance with TRS 430. The acceptance criteria have been applied for a comparison between the values of MUs generated by TPS and the calculated manually ones. The beams have been characterized for Eclipse with data transferred from CadPlan and with data from recommissioning of accelerators, so for these tests it was found a difference of at least 3% for the conformal field shape for the data originated in the beams of recommissioning and at least 4% for the data proceeded from CadPlan. The tolerance level established by TRS 430 for this setting was 3%.

Porém, nenhum deles usou de crowdsourcing para recomendação de centros clínicos de saúde. Segundo Chatzimilioudis crowdsourcing refere-se "a um modelo distribuído de solução de problemas em que uma multidão de tamanho indefinido é contratada para resolver um problema complexo através de um convite aberto". Neste âmbito, este trabalho apresenta um modelo de sistema de recomendação de centros clínicos de saúde, chamado CrowdHealth. A principal contribuição do modelo de sistema de recomendação de centros clínicos é possibilitar a criação de uma relação ganha-ganha entre seus usuários que podem ser cidadãos, médicos ou ainda entidades ligadas ao governo. Na literatura encontramos alguns trabalhos que carecem a abordagem do uso de crowdsourcing como fonte de dados para recomendação de centros clínicos de saúde. Nós desenvolvemos um protótipo de aplicação baseada no modelo de sistema de recomendação de centros clínicos de saúde para proporcionar uma visão do que seria uma aplicação baseada no modelo de sistema de recomendação de centros clínicos de saúde. Para avaliar o nosso modelo, apresentamos um cenário hipotético baseado numa possível aplicação para mensurar a percepção dos usuários quanto a utilidade dos centros clínicos de saúde. Os cenários descritos levavam em consideração os seguintes critérios: (1) a distância entre do usuário ao centro clinico, (2) a avaliação dos usuários em relação ao atendimento recebido nos centros clínicos e (3) o tempo de atendimento informado pelos usuários. Desta forma realizamos uma simulação de requisições de recomendações de usuários usando um dataset real contendo informações do Foursquare. O arquivo do dataset possuia 227428 check-in’s na cidade de Nova Iorque, EUA. O arquivo, foi dividido em duas partes, onde a primeira representava os check-in’s realizados pelos usuários nos centros clínicos, e a segunda representava usuários requisitando por recomendações de centros clínicos em outros locais. Assim, foram criadas funções para simular os processos de cálculo do tempo de atendimento e avaliação dos centros clínicos por parte dos usuários. Também simulou-se usuários requisitando por recomendações de centros clínicos em outros locais. Então, medimos precisão e recuperação dos centros clínicos de saúde sugeridos para cada usuário. Obtivemos valores médios de 57,5% e 61,33% para precisão e recuperação, respectivamente. Com isso, nossa avaliação retrata que centros clínicos de saúde recomendados por uma aplicação baseada no CrowdHealth poderiam aumentar beneficamente a utilidade de centros clínicos de saúde recomendados para os usuários. / With the emergence of crowdsourcing with the worldwide spread of smartphones recent efforts and important research on the use of crowdsourcing in health or smart-health are intended to assist in improving health habits, construction of historical long-term medical personnel, medical analysis and data review, control diets, stress management, analysis and comparison of information and real-time assistance for disasters. However, none of them used the crowdsourcing for recommendation clinical health centers. In this context, this paper presents a model of clinical health centers recommendation system called CrowdHealth. The main contribution of clinical health centers recommendation system model is possible to create a win-win relationship between its users that can be citizens, doctors or entities linked to the government. In the literature we find some papers that require the use of crowdsourcing as a data source for recommendation clinical health centers approach. We have developed a prototype application based on clinical health centers recommendation system model to provide a vision of what would be an application based on the clinical health centers recommendation system model. To evaluate our model, we present a hypothetical scenario based on a possible application to measure the perception of users and the utility of clinical health centers. The scenarios described took into consideration the following criteria: (1) the distance from the user to the clinical center, (2) the evaluation of other users on the service received in the clinical centers and (3) the time of service reported by users. Thus we performed a simulation of user requests recommendations using a real dataset containing information of Foursquare. The file dataset haved 227428 check in’s in New York City, USA. The file was divided into two parts, where the first represented the textit check in ’s performed by users in clinical centers, and the second represented by requesting users polyclinics recommendations elsewhere. Thus, functions were created to simulate service time calculation and evaluation processes of polyclinics by users. Also users was simulated by ordering polyclinics recommendations elsewhere. So we measure precision and recall of health clinical centers suggested for each user. Average values obtained from 57.5 % and 61.33 % for precision and recall, respectively. Thus, our assessment that portrays clinical health centers recommended by an application based on CrowdHealth could increase beneficially the usefulness of clinical health centers recommended for users.

Alcohol is the cause of 3.3 million deaths per year. The Members of WHO are forced to adopt these recommendations because its binding character; a fact that was ruled by Brazil, culminating in the PNA (acronym for Alcohol National Policies). However, to accomplish empirically each guideline, Brazil is far from achieving its national and international goals and is also responsible for international violations of human rights by omission on reducing the harmful consumption of alcoholic beverages. / O tema versa sobre as políticas públicas da OMS, que recomendou na 63ª Assembleia Geral de Saúde dez diretrizes para reduzir o consumo abusivo de bebidas alcoólicas, causa de 3,3 milhões de mortes anuais. Por tratar-se de uma recomendação advinda de uma Organização internacional, entende-se o caráter vinculante desta, obrigando seus Estados-Membros a aplicarem as referidas diretrizes, que inclusive foi normatizada pelo Brasil, culminando na PNA. Contudo, ao depararmos com o estudo realizado de forma empírica sobre cada diretriz (10 ao todo), constatou-se que o Brasil está longe de alcançar os objetivos internacionais e nacionais, tornando-se responsável por violar o direito humano à saúde devido à sua omissão na redução do consumo indevido de bebidas alcoólicas.

Background: Hearing aid prescriptive recommendations for hearing losses having a conductive component have received less clinical and research interest than for losses of a sensorineural nature; as a result, much variation remains among current prescriptive methods in their recommendations for conductive and mixed hearing losses (Johnson and Dillon, 2011). Purpose: The primary intent of this brief clinical note is to demonstrate differences between two algebraically equivalent expressions of hearing loss, which have been approaches used historically to generate a prescription for hearing losses with a conductive component. When air and bone conduction thresholds are entered into hearing aid prescriptions designed for nonlinear hearing aids, it was hypothesized that that two expressions would not yield equivalent amounts of prescribed insertion gain and output. These differences are examined for their impact on the maximum power output (MPO) requirements of the hearing aid. Subsequently, the MPO capabilities of two common behind-the-ear (BTE) receiver placement alternatives, receiver-in-aid (RIA) and receiver-in-canal (RIC), are examined. Study Samples: The two expressions of hearing losses examined were the 25% ABG + AC approach and the 75% ABG + BC approach, where ABG refers to air-bone gap, AC refers to air-conduction threshold, and BC refers to bone-conduction threshold. Example hearing loss cases with a conductive component are sampled for calculations. The MPO capabilities of the BTE receiver placements in commercially-available products were obtained from hearing aids on the U.S. federal purchasing contract. Results: Prescribed gain and the required MPO differs markedly between the two approaches. The 75% ABG + BC approach prescribes a compression ratio that is reflective of the amount of sensorineural hearing loss. Not all hearing aids will have the MPO capabilities to support the output requirements for fitting hearing losses with a large conductive component particularly when combined with significant sensorineural hearing loss. Generally, current RIA BTE products have greater output capabilities than RIC BTE products. Conclusions: The 75% ABG + BC approach is more appropriate than the 25% ABG + AC approach because the latter approach inappropriately uses AC thresholds as the basis for determining the compression ratio. That is, for hearing losses with a conductive component, the AC thresholds are not a measure of sensorineural hearing loss and cannot serve as the basis for determining the amount of desired compression. The Australian National Acoustic Laboratories has been using the 75% ABG + BC approach in lieu of the 25% ABG + AC approach since its release of the National Acoustic Laboratories—Non-linear 1 (NAL-NL1) prescriptive method in 1999. Future research may examine whether individuals with conductive hearing loss benefit or prefer more than 75% restoration of the conductive component provided adequate MPO capabilities to support such restoration.

In spite of a 2009 memorandum from senior Air Force leaders calling for civilian employees to participate in nonresident Professional Military Education (PME) courses, employees' PME completion rates have remained low. This qualitative study investigated the perceptions of nonresident PME held by 12 employees at an installation with a nonresident PME completion rate of less than 3% in 2013. The theories of reasoned action and planned behavior guided the 5 main questions that asked participants to describe their familiarity with nonresident PME course content, availability, and structure; as well as their perceptions of organizational support for PME course participation, their capacity to complete PME courses, the role of nonresident PME in their leadership development, and the importance of PME completion for attaining their career goals. The data were manually coded and organized according to the emergent themes and subthemes. None of the participants identified any external barriers to nonresident PME completion, but factors such as supervisor support, prior participation in enlisted PME, personal interest in PME course content, and inconsistent hiring practices influenced participants' perceptions of nonresident PME for their professional development and career progression. The findings and prior research suggest the Air Force should educate PME eligible civilians regarding the benefits of nonresident PME, conduct focus groups to discover employees' specific learning needs, and assist supervisors in establishing effective mentoring relationships. These actions have the potential to enhance employee motivation, to align employee development with organizational goals and objectives, and to increase supervisor-subordinate collaboration.

Background: The value of stock recommendations have been debated for a century andthe debate has escalated since Alfred Cowles (1933) published his research in “Can StockMarket Forecasters Forecast”? As of late, savings in stocks has increased and the householdsare managing their savings more actively. The consequence of the increased interestin stocks has resulted in a growing market for stock recommendations. Not just financialmedia but daily newspapers have embraced this new found interest, hence stock recom-mendations can be found in almost all large newspapers in Sweden. Furthermore, this phe-nomenon has also lead to intensified research within stock recommendations. Researchers have under the 20th and 21st century investigated a wide number of issues concerning stock recommendations. The most common issue with different angles has been whether stockrecommendations generate abnormal returns or not? Earlier research on this issue havehowever mostly been based on the American stock market. According to us, not enoughnational research has been done on whether stock recommendations generate abnormal returnsor not on the Swedish stock market. Further we think that there is a lack of research with regards to a short time span. Purpose: The purpose of the study is to investigate whether stock recommendations on Nasdaq OMXSLarge-Mid-Small CAP, First North and Aktietorget generate abnormal returns? Central for the study is to investigate if stock recommendation generates abnormal returns in the short-term. Secondary the study will also investigate stock recommendations effect on stock prices in the long run. Method: First step was to create databases from high frequency data, 10 minute OHLCVbars, and from closing prices. Thereafter use these as a base for statistical calculations. Conclusion: The results from this study show that analysts have succeeded with generat-ing significant abnormal returns with their recommendations. Above all it is the business journals buy recommendations that generate the highest abnormal return. Sell recommen-dations didn’t give high significant results in our measurements. Our results also show thatabnormal returns from buy recommendations are sufficiently high and the transaction costsare sufficiently low so that investors can capitalize on the analyses. We found that buy recommendations effect companies noted on Small Cap etc to a higher extent than companies noted on Large- and Mid-Cap because of the lower degree of transparency in the smaller companies. Our results also indicate that the weekly magazines generate approximatelyequal abnormal returns. The monthly generates the lowest abnormal returns in our study. In our research we also found that buy recommendations that are published when thestock market has a positive momentum perform better than when the stock market has anegative momentum. We also found that investor should closely monitor the information flow before the recommendation is published, since a positive information flow can have afavorable outcome on the size of the abnormal return. Last but not least, we observe a correlationbetween the numbers of investors the recommendation reaches and the magnitudeof the observed abnormal return. / Bakgrund: Värdet av aktierekommendationer har debatterats i snart ett sekel, och debat-ten har eskalerat ända sedan Alfred Cowles (1933) publicerade sin forskning ”Can StockMarket Forecasters Forecast?" De senaste åren har sparandet i aktier ökat och hushållenblir allt aktivare i sitt pensionssparande. Konsekvensen av det ökade intresset för sparande iaktier har resulterat i en växande marknad för aktierekommendationer. Inte bara finansiellmedia utan också dagliga tidskrifter har tagit till sig detta ökade intresse och nästan samtligastörre dagstidningar publicerar numera aktierekommendationer. Vidare har detta fenomen också lett till att forskningen kring aktierekommendationer intensifierats de senaste decennierna.Forskare har under 1900-talet och 2000-talet undersökt en mängd olika problem-ställningar kring aktierekommendationer. Varav den vanligaste problemställningen med varierandevinklar, har varit huruvida aktierekommendationer genererar överavkastning ellerej? Tidigare forskning har dock framförallt baserats på den amerikanska aktiemarknaden. I vår mening råder det brist på nationell forskning som visar huruvida aktierekommendatio-ner genererar överavkastning på bolag noterade på svenska marknadsplatser. Vidare råderdet brist på forskning som tar hänsyn till det korta tidsperspektivet. Syfte: Syftet med studien är att undersöka huruvida aktierekommendationer på Nasdaq OMXS Large-Mid-Small CAP och First North samt Aktietorget genererar överavkastning? Centralt för studien är attundersöka om aktierekommendationer är kursdrivande på kort sikt, Sekundärt kommer också studienundersöka aktierekommendationers inverkan på aktiekurser på lång sikt. Metod: Första steget var att konstruera databaser från högfrekvensdata, 10M OHLCVbars, och stängningskurser. Därefter använda dessa som grund för statistiska beräkningar. Slutsats: Resultat från vår studie visar att ekonomijournalister har lyckats med att genererasignifikant överavkastning med deras rekommendationer. Framför allt är det affärstidskrifternasköprekommendationer som genererar högst överavkastning. Säljrekommendationergav ett lägre signifikant utslag i våra mätningar. Våra resultat indikerar också på att överavkastningen från köprekommendationer är tillräckligt hög och transaktionskostnaderna tillräckligtlåga för att investerare skall kunna kapitalisera på rekommendationerna. Vi finneratt köprekommendationer är mer kursdrivande på Small Cap etc. än bolag noterade på Lar-ge- och Mid Cap på grund av den lägre graden av transparens i de mindre bolagen. Våra resultatpekar också på att Affärsvärlden, Börsveckan & Veckans affärer genererar ungefärlika stor överavkastning. Aktiespararen & Privata Affärer genererar den lägsta överavkastningeni våra mätningar. I våra efterforskningar ser vi också en stark tendens för att aktiersom rekommenderas när börsen har ett positivt momentum presterar bättre än aktier somrekommenderas när börsen har ett negativt momentum. Vi finner också att investerare börbeakta informationsflödet innan rekommendationstidpunkten då ett positivt informations-flöde kan får en gynnsam effekt på överavkastningens storlek. Sist men inte minst observe-rar vi en korrelation mellan antalet investerare rekommendationen når och magnituden påden observerade överavkastningen.

Two hundred and fifty-four University of South Florida students were used in this study. The majority of these participants were undergraduate, psychology majors, female, and between the ages of 17 and 23. Participants were given statements describing a teacher's performance and were asked to evaluate the professor on citizenship and overall performance and recommend them for rewards. No support was found for the hypothesis that men would have a stronger relationship than women between citizenship and overall performance. No support was found for the hypothesis that men would have a stronger relationship than women between citizenship performance and reward recommendations. Scale type was not found to influence these relationships. / ABSTRACT: These results are not consistent with the shifting standards model. Numerous suggestions are made for changes to the experiment, including performing a field study instead of a lab study. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

This paper explores public health campaigns as they relate to tweens and their use of technology. After considering how this demographic utilizes both traditional and new media, further examination was done on general health problems that affect this group. Three major health issues were then chosen for analysis. A relevant campaign for each issue was also evaluated, as were its overall marketing and communication efforts. The health problems and corresponding campaigns chosen include childhood obesity and the “Let’s Move” campaign, electronic aggression and the “Stop Bullying” campaign and youth suicide and the “WeCanHelpUs” campaign. From these analyses, recommendations for ways to improve each campaign were provided, as were general conclusions for reaching this demographic more efficiently and effectively. / text
