This paper discusses distribution and the historical phases of capitalism. It assumes that technical progress and growth are taking place, and, given that, its question is on the functional distribution of income between labor and capital, having as reference classical theory of distribution and Marx’s falling tendency of the rate of profit. Based on the historical experience, it, first, inverts the model, making the rate of profit as the constant variable in the long run and the wage rate, as the residuum; second, it distinguishes three types of technical progress (capital-saving, neutral and capital-using) and applies it to the history of capitalism, having the UK and France as reference. Given these three types of technical progress, it distinguishes four phases of capitalist growth, where only the second is consistent with Marx prediction. The last phase, after World War II, should be, in principle, capital-saving, consistent with growth of wages above productivity. Instead, since the 1970s wages were kept stagnant in rich countries because of, first, the fact that the Information and Communication Technology Revolution proved to be highly capital using, opening room for a new wage of substitution of capital for labor; second, the new competition coming from developing countries; third, the emergence of the technobureaucratic or professional class; and, fourth, the new power of the neoliberal class coalition associating rentier capitalists and financiers

Nos últimos anos, o mundo vem assistindo a um maior número de mobilizações sociais, que ocorrem em todo o espectro de regimes de governo e níveis de desenvolvimento econômico: de países tradicionalmente democráticos e desenvolvidos, a países em desenvolvimento sob regimes autoritários. Tais mobilizações vêm ocorrendo simultaneamente a uma expansão acelerada das Tecnologias da Informação e Comunicação (TIC), mais notadamente o avanço da Internet e dos telefones celulares (ITU, 2014; CETIC, 2013), tornando mais rápido e fácil o acesso e difusão de informações sem o intermédio dos meios de comunicação de massa tradicionais; há os que defendem que o contexto de cada nação é o grande responsável por tais manifestações, enquanto outros citam a importância tanto das TIC quanto dos fatores contextuais como influenciadores. O objetivo desta pesquisa é identificar as variáveis explicativas da ocorrência de protestos, considerando aspectos tecnológicos, sociais e políticos, por meio da construção de modelos utilizando dados em painel. Para tal são utilizados dados do Banco Mundial, Fórum Econômico Mundial e ITU, desenvolvendo uma amostra de 124 países. O resultado desta análise revela que o percentual de usuários de Internet influencia positivamente a ocorrência de protestos e que países desenvolvidos possuem maior a chance de apresentarem manifestações.

O desafio de ofertar infraestrutura de serviços públicos nas regiões menos desenvolvidas do Brasil, geralmente mais afastadas dos grandes centros urbanos, mobiliza setores da sociedade na busca de abordagens novas e criativas que possam diminuir as grandes disparidades inter-regionais. Uma das carências vivenciadas por parte da população brasileira é a falta de acesso ao sistema financeiro, comprometendo a capacidade de plena participação dessas pessoas na economia, dificultando a geração e acúmulo de riqueza, situação essa presente na Ilha de Marajó, no estado do Pará, cuja maioria de seus dezesseis municípios apresenta Índice de Desenvolvimento Humano (IDH) baixo ou muito baixo. Para mudar essa realidade, uma iniciativa inovadora é a agência bancária itinerante instalada em barco, para atendimento a populações ribeirinhas de regiões com vasta extensão territorial, baixa densidade demográfica, dificuldades de transporte e limitações na oferta de tecnologia da informação e comunicação (TIC). Assim, essa pesquisa, com propósito exploratório e descritivo, tem como objetivo principal identificar, sob o ponto de vista das TIC, como os indicadores de inclusão financeira são influenciados pela atuação da Agência Barco na Ilha de Marajó. Além do estudo teórico, foi realizada investigação empírica, por meio de observação direta e entrevistas semiestruturadas com clientes e funcionários da Agência Barco, realizadas ao longo de quatro dias, em duas cidades da Ilha de Marajó. Para análise dos dados, foram aplicadas técnicas de análise de conteúdo às entrevistas, com objetivo de identificar a presença de elementos de inclusão financeira, transpondo os resultados para um modelo heurístico de infoinclusão dinâmica (2iD), o qual foi adaptado para contemplar constructos de inclusão financeira. O resultado da pesquisa demonstra que a Agência Barco consegue suprir as necessidades de acesso a serviços e produtos financeiros pela população da Ilha de Marajó, ao mesmo tempo em que se identifica oportunidades para ampliação de aspectos relacionados à educação financeira, possibilitando fortalecer os componentes dinâmicos do processo de inclusão financeira, com aumento da conscientização e consequente aumento da demanda por serviços e produtos financeiros.

O mercado de telecomunicações mundial, em geral e brasileiro em particular, passou por mudanças significativas ao longo dos últimos dez anos, tanto em âmbito concorrencial, como regulatório. O modelo de serviço único prestado por empresas distintas foi transformado pela convergência de indústrias, com a criação de novas ofertas e proposições de valor a partir de um portfólio diversificado e complementar de serviços aos consumidores. Estes fatos criaram para as empresas que operam no setor a necessidade de revisão de suas cadeias de valor para adequarem-se à nova dinâmica da indústria. Ainda que esse processo venha ocorrendo ao longo dos últimos anos, há poucos estudos que procurem endereçar os impactos para a realidade brasileira. O propósito desse trabalho é o de avaliar os efeitos para a configuração da cadeia de valor que a convergência de indústrias no setor de telecomunicações brasileiro trouxe para o estudo de caso. Para endereçar a resposta à pergunta de pesquisa, primeiro é conduzida uma revisão teórica sobre a definição do setor de TICs (FRANSMAN, 2010), a relação com a indústria de telecomunicações e os aspectos que marcam o caso brasileiro. Em segundo, é feita a revisão teórica para as definições constitutivas relacionadas à convergência de indústrias (HACKLIN, F. et al., 2009), cadeia de valor (PORTER, 1985) e rede de valor (PIL e HOLWEG, 2006; MÖLLER e RAJALA, 2007; PARTANEN e MÖLLER, 2012). A partir da constituição teórica e a análise dos dados qualitativos pretende-se aplicar os conceitos ao estudo de caso brasileiro e verificar se há alguma configuração da cadeia de valor que seja referência para melhor lidar com os efeitos da convergência de indústrias. Como ferramenta de coleta de dados serão feitas entrevistas para constituir os aspectos mais relevantes das mudanças causadas pela convergência de indústrias e entender as transformações consequentes para as cadeias de valor.

Since some years, mobile technologies in healthcare (mHealth) stand for the transformational force to improve health issues in low- and middle-income countries (LMICs). Although several studies have identified the prevailing issue of inconsistent evidence and new evaluation frameworks have been proposed, few have explored the role of entrepreneurship to create disruptive change in a traditionally conservative sector. I argue that improving the effectiveness of mHealth entrepreneurs might increase the adoption of mHealth solutions. Thus, this study aims at proposing a managerial model for the analysis of mHealth solutions from the entrepreneurial perspective in the context of LMICs. I identified the Khoja–Durrani–Scott (KDS) framework as theoretical basis for the managerial model, due to its explicit focus on the context of LMICs. In the subsequent exploratory research I, first, used semi-structured interviews with five specialists in mHealth, local healthcare systems and investment to identify necessary adaptations to the model. The findings of the interviews proposed that especially the economic theme had to be clarified and an additional entrepreneurial theme was necessary. Additionally, an evaluation questionnaire was proposed. In the second phase, I applied the questionnaire to five start-ups, operating in Brazil and Tanzania, and conducted semi-structured interviews with the entrepreneurs to gain practical insights for the theoretical development. Three of five entrepreneurs perceived that the results correlated with the entrepreneurs' expectations of the strengths and weaknesses of the start-ups. Main shortcomings of the model related to the ambiguity of some questions. In addition to the findings for the model, the results of the scores were analyzed. The analysis suggested that across the participating mHealth start-ups the ‘behavioral and socio-technical’ outcomes were the strongest and the ‘policy’ outcomes were the weakest themes. The managerial model integrates several perspectives, structured around the entrepreneur. In order to validate the model, future research may link the development of a start-up with the evolution of the scores in longitudinal case studies or large-scale tests.

The Participatory Democracy is disseminated throughout the Principle of Popular Sovereignty. Since it spurs the participation of the people in the exercise of political power, it emerges as a conciliatory alternative to the Representative Regime - one of questionable legitimacy in account of the distortion it causes on the will of the public. It does so specially vis-à-vis the legislative, where the law is created. It s known that our Constitution (arts. 1º e 14, CF/88) provides for the means through which the members of the public may take part in the political process of the country, for it consecrates the plebiscite, the referendum and the popular initiative, all of them incipiently regulated by the Lei nº 9.709/98. It s our task, thus, to inquire, through deductive reasoning as well as the legal exegeses, the enforceability of the Popular Initiative as a means of popular emancipation, given that it enables the citizens to conscientiously participate in the public sphere. It has also an educational ethos which builds the capacity of individual to act, and, therefore, through thoughtful choices, enhance the legal system. Furthermore, the Lei da Ficha Limpa (LC nº 135/2010) surely represents a milestone in the Brazilian political history, since it accrued from a new way of social interaction allowed by the usage of communication technology on the pursuit of political morality. As a matter of fact, this bill is a clear example of how a legal act was legitimately proposed through Public Initiative. Hence, it s beneficial to actually make use of the Public Initiative, under the influence of the New Constitutional Hermeneutics, with a view to supporting social claims and promoting a dialogical relationship with the State in order to help it in the decisionmaking process. Thereat, we can achieve important civic spaces through which the fundamental right to democracy shall be materialized, tearing apart the old paradigms of inequality and, thus, promoting social justice

One of the best examples of the Information and Communication Technology (ICT) evolutions is on the high capability of storing and processing data into smaller devices, creating a new business condition, the mobility . This mobility in a deeper analysis proposes a business remodeling in many different areas (business segmentations), through the Internet anywhere at any time, allowing managers and researchers to think again their actual models that work nowadays in companies and public institutions, modifying the way internal and external clients can be attended. This thesis analyzes issues on mobile business adoption, technological evolutions and the impacts caused by this new reality the access to information anywhere at any time . This research is exploratory and shows a compilation of similar papers and thesis describing how was conducted the survey within 50 companies in the states of Rio Grande do Norte, Pernambuco and Ceará. The statistics analysis showed the different level of mobile technology usage from simple voice communications to wide band data transmission. The analysis pointed that canonic correlation was the most effective type of analysis to describe the relations among all groups of variables showing which of them are relevant, or not, for mobile technology adoption

This Masters degree dissertation presents a research that aims at analyzing the activities regarding within a hotel managers work in Natal/RN - Brazil, This Masters degree dissertation presents the research that aims at analyzing the activities regarding the hotel managers work in Natal / RN - Brazil, performing diagnosis of their activities and relating the aspects that impact the quality and productivity of hotel services and managers occupational health. This research is characterized as a case study with a qualitative approach, taking the method of Ergonomic Work Analysis which is the analysis of the managers work activity as a reference to the focus; and combining the use of observational and interactional methods. Ergonomics and macroergonomics are used in this study not only to understand the physical, cognitive and organizational constraints of the manager s duties, but also to characterize the work organizational architecture and design of that hotel. High workload, accumulation of tasks and diversion of functions performed by managers were noticed, increasing thereby the physical and psychological suffering for them. It was found that the activity of managers is characterized by the ambivalence of power, limited autonomy, cooperation, interdependence between managers and the fear of incompetence. It was also noticed that managers devote more time to the day job (37%), another time to sleep (30%), while only 33% of the rest of the day are meant for activities like taking care of health, family, social life and study. Although there are few studies addressing the health and safety of hotel managers, this research revealed that 84% of the surveyed hotel managers complain of musculoskeletal pain which 50% are obese and are 100% sedentary. It was also observed that managers adopt unsuitable postures for carrying out the work activities that contribute to becoming injured or work-related musculoskeletal disorders in the near future. Ergonomic measures were recommended as an investment in the skills and the training of managers, encouraging cooperative work, appropriateness of workload, limiting overtime, preserving the enjoyment of breaks during work and weekly holidays, changing the layout of the work sector , usage of communication technology to prevent displacement, compensatory physical activities, furniture adaptation, among others

The greater part of monitoring onshore Oil and Gas environment currently are based on wireless solutions. However, these solutions have a technological configuration that are out-of-date, mainly because analog radios and inefficient communication topologies are used. On the other hand, solutions based in digital radios can provide more efficient solutions related to energy consumption, security and fault tolerance. Thus, this paper evaluated if the Wireless Sensor Network, communication technology based on digital radios, are adequate to monitoring Oil and Gas onshore wells. Percent of packets transmitted with successful, energy consumption, communication delay and routing techniques applied to a mesh topology will be used as metrics to validate the proposal in the different routing techniques through network simulation tool NS-2

Considering the following conditions: (1) the fluency demands of students in an undergraduate program in Languages and Literatures/English in the Amazon region; (2) the listening and speaking needs of pre-service teachers of English as a Foreign Language (EFL); (3) my continuing education as a professor of EFL and my academic literacy as a teacher-researcher and pre-service-teacher trainer, this study, which is based on Narrative Inquiry, reports on a teacher experience of working didactically with oral genres through podcasting an activity that emerged with the advent of Information and Communication Technology (ICT). Through this process, I engage with some theorists who promote teaching as a process that is driven by a concept of language as social practice. Subsequently, I make use of the notions of context of culture and context of situation, derived from Systemic Functional Linguistics, as well as the concept of genre and register derived from the perspective of this theory. Based on these principles and beliefs, the Amazon region constitutes the register (situation) of the genres used in this study. These principles also provide, opportunities for building learning strategies appropriate to this local context, and also to teach listening and speaking skills from a task-based approach. During the experience, based on the reflective teacher-education model, the participants produced narratives about the process, which I then analyzed according to Ely, Vinz, Downing and Anzul (2001), who propose possibilities of composing meanings in Narrative Inquiry. Based on this perspective, I discuss the following topics, which were highly emphasized in the participants narratives: the lack of didactic activities using oral genres; the relevance of context within teacher education; and collaborative work as a strategy to overcome gaps in digital literacy, language fluency and teaching skills. The meanings I thereby compose point to a paradigm shift in English language teaching within this context. I also argue for a pedagogical practice that is engaged with historical and socio-cultural issues, and with the development of language skills, also one that promotes the implementation of ICTs at the very start of teacher training programs, adopting teaching and learning strategies that correspond to the demands of fluency in this particular context, and deficiencies imposed by geographical isolation

This research aims to understand the relationship between media, capitalism and ownership of free time for leisure practices in industrial societies and postindustrial. Searching is thus a conceptual framework that takes into account the kind of ideology that naturalizes the relationship of leisure with the foundations of contemporary media, and the media only with leisure, forgetting their insertion in the labor and industrial relations in society. We intend to demonstrate that every mode of production, in the capitalist system, entails a mode of reproduction. Methodologically, this is a first approximation, from theoretical concerns already performed, constituting a theoretical research, bibliographic and descriptive character. The results of the text drives us to the conclusion that the work and leisure spheres tend to be less and less differentiated, since both remain as activities of product management with the same intellective protocols, based on information and communication technology, and that accordingly, the media favors an expansion of productive activity even during leisure time

The increase of higher education offer is a basic need of developed and emerging countries. It requires increasing and ongoing investments. The offer of higher education, by means of Distance Learning, based on the Internet, is one of the most efficient manners for the massification of this offer, as it allows ample coverage and lower costs. In this scenario, we highlight Moodle, an open and low-cost environment for Distance Learning. Its utilization may be amplified through the adoption of an emerging Information and Communication Technology (ICT), Cloud Computing, which allows the virtualization of Moodle sites, cutting costs, facilitating management and increasing its service capacity. This article diffuses a public tool, opened and free, for automatic conversion of Moodle sites, such that these may be hosted on Azure: the Cloud Computing environment of Microsoft.
