Low-Cost Cloud-Based Design of Smart Rural Energy Device in Microgrid: Perspective India An Energy-On-Demand Service for Rural India

In this paper we present a combination of technologies to provide an Energy-on-Demand (EoD) service to enable low cost innovation suitable for microgrid networks. The system is designed around the low cost and simple Rural Energy Device (RED) Box which in combination with Short Message Service (SMS) communication methodology serves as an elementary proxy for Smart meters which are typically used in urban settings. Further, customer behavior and familiarity in using such devices based on mobile experience has been incorporated into the design philosophy. Customers are incentivized to interact with the system thus providing valuable behavioral and usage data to the Utility Service Provider (USP). Data that is collected over time can be used by the USP for analytics envisioned by using remote computing services known as cloud computing service. Cloud computing allows for a sharing of computational resources at the virtual level across several networks. The customer-system interaction is facilitated by a third party Telecom Service provider (TSP). The approximate cost of the RED Box is envisaged to be under USD 10 on production scale.

Os efeitos da cidade digital: o direito à privacidade e à liberdade de informação

O presente trabalho analisa a formação da cidade digital nas relações sociais, ressaltando os efeitos da garantia do direito à privacidade no ambiente dos navegantes de sites e redes sociais, em função das repercussões jurídicas do vazamento de informações da vida pessoal dos usuários da rede, e do tratamento dos dados coletados pelos prestadores de serviço. Através do ciberespaço formam-se comunidades virtuais que ultrapassam a necessidade de localidade e sociabilidade, criando um isolamento social e abandonando as interações face a face em ambientes reais, originando uma sociabilidade baseada no individualismo. Avaliamos os novos padrões de interação que se originam nesta nova formatação de coletividade informacional e suas repercussões no âmbito do direito. Em uma perspectiva mais detalhada, esse estudo indica quais as hipóteses de responsabilidade civil dos provedores na Internet em decorrência de atos ilícitos cometidos por terceiros e as alternativas de um sistema de tutela da privacidade à proteção de dados, face à lesão no ambiente informacional. O levantamento das possíveis situações de responsabilização civil foi efetuado através da análise da jurisprudência e da doutrina dominante, ressaltando os aspectos fáticos que caracterizam sua formatação. Esse modelo se impõe, através de uma relação hierárquica a uma multiplicidade de indivíduos, criando um encarceramento perfeito através do exercício do biopoder. Tais papéis são reforçados por uma cultura consumista e a sociedade do espetáculo, que transforma o indivíduo em mercadoria levantando perfis de usuários conectados em rede, propiciando uma categorização dos consumidores. Nesse contexto, apresentamos os riscos de uma sociedade de vigilância que se apresenta factível como um produto das relações de mercado, que possibilita dispor livremente de um conjunto crescente de informações. Esta constante vigilância invade todos os espaços, custodiando nosso comportamento independente do tempo, com uma implacável memória no âmbito das comunicações eletrônicas, tornando nosso passado eternamente visível e fazendo surgir situações constrangedoras a nos assombrar.

O direito humano de acesso à internet

O tema da dissertação é o direito humano de acesso à internet. O primeiro capítulo busca afirmar a existência desse direito e seu caráter essencial. Para isso, são apresentados fundamentos de quatro espécies. O primeiro é de direito internacional dos direitos humanos e baseia-se na análise de três documentos da Organização das Nações Unidas. O segundo é material e procura demonstrar que a internet tornou-se um instrumento indispensável à realização de diversos deveres e direitos, muitos deles humanos. Dessa forma, o acesso deve ser considerado um direito em si, dotado do mesmo status jurídico dos direitos dele dependentes. O terceiro fundamento é filosófico. Ressalta-se o aspecto comunitário da internet e demonstra-se que há um cidadão virtual que é titular de direitos e deveres na rede. Nesse momento, com base na lição de Hannah Arendt, é afirmado que se há uma dimensão digital da cidadania, deve haver um direito a adquiri-la, o que se dá pelo direito de acesso à internet. O quarto fundamento é positivo e direciona-se especificamente ao reconhecimento de um direito fundamental de acesso à internet na ordem constitucional brasileira, decorrente e não escrito. Após, é feito um estudo de direito comparado, analisando-se como a questão tem sido tratada pela lei e pela jurisprudência de diversos países. Ao final do primeiro capítulo, são apresentadas e refutadas as objeções mais comuns ao reconhecimento do direito humano de acesso à internet, incluindo a questão dos custos do direito. Afirmada a existência do direito, o segundo capítulo analisa seu conteúdo e seus limites jurídicos. Inicialmente, o direito é subdividido em uma dimensão de acesso à infraestrutura física e uma dimensão de acesso ao conteúdo. São apresentadas as principais políticas públicas brasileiras que visam a concretizar ambas as dimensões. Em um segundo momento, são estudadas hipóteses de violação do direito. Uma hipótese de lesão é a ausência do serviço em certas localidades. Outra hipótese é a censura virtual, que é dividida em função do método utilizado, se pelo hardware ou pelo software, e em função do agente que a realiza, se estatal ou privado. É analisada a constitucionalidade de penas de desconexão, perpétuas ou temporárias, e de medidas de interrupção total do serviço, em conjunto com a Lei 12.737/2012. São apresentados requisitos para que as filtragens de conteúdo na rede sejam lícitas. Coteja-se o estudado com o Projeto de Lei 2.126/2011, o chamado marco civil da internet. Por fim, é estudada a exigibilidade do direito com relação às duas dimensões.

Management Driven Hybrid Multicast Framework for Content Aware Networks

The need for better adaptation of networks to transported flows has led to research on new approaches such as content aware networks and network aware applications. In parallel, recent developments of multimedia and content oriented services and applications such as IPTV, video streaming, video on demand, and Internet TV reinforced interest in multicast technologies. IP multicast has not been widely deployed due to interdomain and QoS support problems; therefore, alternative solutions have been investigated. This article proposes a management driven hybrid multicast solution that is multi-domain and media oriented, and combines overlay multicast, IP multicast, and P2P. The architecture is developed in a content aware network and network aware application environment, based on light network virtualization. The multicast trees can be seen as parallel virtual content aware networks, spanning a single or multiple IP domains, customized to the type of content to be transported while fulfilling the quality of service requirements of the service provider.

Service quality and reliability assessment of mobile communication infrastructure

The service quality of any sector has two major aspects namely technical and functional. Technical quality can be attained by maintaining technical specification as decided by the organization. Functional quality refers to the manner which service is delivered to customer which can be assessed by the customer feed backs. A field survey was conducted based on the management tool SERVQUAL, by designing 28 constructs under 7 dimensions of service quality. Stratified sampling techniques were used to get 336 valid responses and the gap scores of expectations and perceptions are analyzed using statistical techniques to identify the weakest dimension. To assess the technical aspects of availability six months live outage data of base transceiver were collected. The statistical and exploratory techniques were used to model the network performance. The failure patterns have been modeled in competing risk models and probability distribution of service outage and restorations were parameterized. Since the availability of network is a function of the reliability and maintainability of the network elements, any service provider who wishes to keep up their service level agreements on availability should be aware of the variability of these elements and its effects on interactions. The availability variations were studied by designing a discrete time event simulation model with probabilistic input parameters. The probabilistic distribution parameters arrived from live data analysis was used to design experiments to define the availability domain of the network under consideration. The availability domain can be used as a reference for planning and implementing maintenance activities. A new metric is proposed which incorporates a consistency index along with key service parameters that can be used to compare the performance of different service providers. The developed tool can be used for reliability analysis of mobile communication systems and assumes greater significance in the wake of mobile portability facility. It is also possible to have a relative measure of the effectiveness of different service providers.

Métodos de análisis de las comunidades de clientes mediante la relación estratégica comunitaria y el marketing.

En este proyecto analizaremos como las organizaciones se relacionan con el medio y marketing. La idea es determinar cuáles son los métodos de análisis de las comunidades de clientes mediante la relación estratégica comunitaria y el marketing. Por medio del mercadeo se puede conocer el entorno y determinar qué métodos de análisis utilizar para conocer a la comunidad de clientes. Las personas de mercadeo se ocupan de todo lo que ocurre en el entorno, de estar al tanto para saber cuándo hay oportunidades que puedan ser provechosas para la organización o por otro lado cuando hay amenazas de las que debe tener cuidado. Dependiendo del entorno, la organización diseña sus actividades de mercadeo enfocadas en satisfacer las necesidades del consumidor. Las actividades del consumidor se conceptualizan en producto, precio, promoción y plaza que se definen y diseñan basados en la comunidad en la que este inmersa la organización. Es importante buscar información confiable sobre el grupo objetivo al cual se le va ofrecer el producto o servicio, ya que toca analizarlos y comprender a estas personas para diseñar una buena oferta que satisfaga sus necesidades y deseos. Esta persona que recibe el producto o servicio por parte de la organización es el cliente. Los clientes son las personas que llegan a una organización en búsqueda de satisfacer necesidades a través de los bienes y servicios que las empresas ofrecen. Es esencial determinar que los clientes viven en comunidad, es decir comparten ideas por la comunicación tan estrecha que tienen y viven en conjunto bajo las mismas costumbres. Debido a estos es que hoy en día, los consumidores se conglomeran en comunidades de clientes, y para saberles llegar a estos clientes, toca analizarlos por medio de diversos métodos. El uso de las estrategias comunitarias es necesario ya que por medio del marketing se analiza el entorno y se buscan los métodos para analizar a la comunidad de clientes, que comparten características y se analizan en conjunto no por individuo. Es necesario identificar los métodos para relacionarse con la comunidad de clientes, para poder acercarnos a estos y conocerlos bien, saber sus necesidades y deseos y ofrecerles productos y servicios de acuerdo a éstos. En la actualidad estos métodos no son muy comunes ni conocidos, es por esto que nuestro propósito es indagar e identificar estos métodos para saber analizar a las comunidades. En este proyecto se utilizara una metodología de estudio tipo teórico-conceptual buscando las fuentes de información necesarias para llevar a cabo nuestra investigación. Se considera trabajar con El Grupo de Investigación en Perdurabilidad Empresarial y se escogió la línea de gerencia ya que permite entrar en la sociedad del conocimiento, siendo capaces de identificar oportunidades gerenciales en el entorno. Es interesante investigar sobre estos métodos, ya que los clientes esperan un servicio excelente, atento y que se preocupe por ellos y sus necesidades.

The impact of broadband quality standards on internet services market structure in Colombia

This paper develops a structural model which allows estimating the impact of regulatory decisions looking for the setting of download-speed standards on market structure and performance. We characterize a setting under which quality standards improve both service quality and availability. As to quality, we evaluate the impact of quality standards on the performance of local demand from a detailed database of broadband internet subscribers, discriminated by the main attributes of an internet subscription contract as location, supplier, monthly-fee, download- and upload-speed features. From these results, we are able to identify the effect of quality regulation on the behavior of internet providers in a differentiated product market approach. As a consequence, we are able to assert that the response of internet service providers to quality regulation is a more intense product differentiation that contributes to demand expansion and therefore to improve broadband penetration indicators.

Accidentes con riesgo biológico en una población afiliada a una ARL, 2014, Colombia

Introducción: Existen condiciones que definen la gravedad de accidentes laborales de tipo riesgo biológico como el contacto con una fuente conocida o desconocida, tipo de exposición según el fluido de contacto, el elemento causante y el tipo de lesión que causa. Objetivo: Describir e identificar la ocurrencia de los accidentes de trabajo con riesgo biológico que tienen la población trabajadora del sector salud y afines, afiliados a una ARL reportados durante el año 2014, suministradas en una base de datos de la IPS encargada del manejo de los eventos, con el fin de destacar su impacto y métodos de prevención de los mismos a través de la ARL. Materiales y métodos: Se realizó un estudio de corte transversal en el que se analizaron datos secundarios procedentes de una base de datos que incluyo los eventos sobre riesgo biológico reportados a una ARL entre el 1 de febrero del 2014 y el 31 de diciembre de 2014, se reportaron 1806 accidentes de tipo riesgo biológico donde se analizaron características sociodemográficas, tipo de fluido, tipo de fuente, tipo de accidente y tipo de elemento.

El sitio de mayor frecuencia de ocurrencia de los accidentes fue el intrahospitalario con 89.5%. La mayor accidentalidad se relacionó con el contacto con sangre y se presentó en trabajadores con nivel universitario (89.8%), seguido por los técnicos (84.6%) y auxiliares (67.3%). Se observó una ocurrencia de accidentes entre trabajadores con nivel primaria y secundaria con un porcentaje de 95.7% y 91.6% respectivamente, quienes además tienen mayor riesgo a tener accidentes con fuentes desconocidas, mientras que los técnicos (68.5%) y los universitarios (80.1%) fueron con fuente conocida. Dentro del grupo de auxiliares se destaca accidentes con fuente desconocida con 53.4%. Debido a la manipulación de elementos cortopunzantes con las manos, los dedos fueron la parte anatómica más afectada (84.1%) con elementos de alto riesgo y específicamente con sangre (77.1%). Conclusiones: El personal del área de la salud fue el más afectado dado el contacto directo con pacientes. Las auxiliares de servicios de salud fueron las más afectadas por tener contacto directo en la manipulación de elementos cortopunzantes con fluidos de alto riesgo como la sangre, y los dedos la parte anatómica más afectada con fuente conocida.

The tenant as a customer: can good service improve real estate performance?

Customer Relationship Management (CRM) theory suggests that good customer service results in satisfied customers, who in turn are more likely to remain loyal and recommend the service provider to others. Proponents of good customer service for tenants claim that landlords should see a return on any investment in their customer service, in the form of enhanced real estate performance. This paper begins by reviewing research on customer service returns in other industries. Through consideration of the characteristics of real estate markets, the paper explains how factors such as (inter alia) lease terms, property market cycles, and property type, might determine the relationship between customer service and real estate performance. The paper concludes that further research is needed to isolate specific aspects of customer service that are most appreciated by customers. It suggests that the financial returns which accrue to landlords adopting a customer-focused approach might indeed be quantified, and suggests an appropriate method for such future research.

Collaboration model for SSMEnetUK: a service science perspective

This paper aims to design a collaboration model for a Knowledge Community - SSMEnetUK. The research identifies SSMEnetUK as a socio-technical system and uses the core concepts of Service Science to explore the subject domain. The paper is positioned within the concept of Knowledge Management (KM) and utilising Web 2.0 tools for collaboration. A qualitative case study method was adopted and multiple data sources were used. In achieving that, the degree of co-relation between knowledge management activities and Web 2.0 tools for collaboration in the scenario are pitted against the concept of value propositions offered by both customer/user and service provider. The proposed model provides a better understanding of how Knowledge Management and Web 2.0 tools can enable effective collaboration within SSMEnetUK. This research is relevant to the wider service design and innovation community because it provides a basis for building a service-centric collaboration platform for the benefit of both customer/user and service provider.

Treating the Tenant as a Customer: can good service improve real estate performance?

Customer Relationship Management (CRM) theory suggests that good customer service results in satisfied customers, who in turn are more likely to remain loyal and recommend the service provider to others. Applied to real estate, this theory implies that landlords should see a return on any investment in the service they give to tenants, in the form of increased lease renewal rates and fewer void periods, achieved without compromising rents. This paper examines determinants of occupier satisfaction, and investigates the relationship between occupier satisfaction and property performance, using measures such as capital growth, income return, lease renewal rates and total return. The analysis is based upon a pilot study using occupier satisfaction responses from around 2500 interviewees based in multi-tenanted offices, shopping centres and retail warehouses on out-of-town retail parks in the UK. The analysis is being extended to cover a larger sample for the author’s PhD. Part 1 of the analysis examines occupier satisfaction, whilst Part 2 considers its impact on property performance.

Intercultural service encounters : an exploratory study of customer experiences

Intercultural contact occurs on a daily basis across all facets of life, and is reflective of Australia’s multicultural society. This trend is observed in many Western industrialised nations and has contributed to a growing body of research and literature in the field of managing cultural diversity. While much of this research is focused on the internal context of the workplace, relatively little attention has been given to the impact of culture on the service provider and customer interface. In an effort to shed some light on the service experiences of culturally diverse customers, a series of exploratory interviews were conducted. The findings suggest that on the basis of service provider behaviors (both verbal and nonverbal), culturally diverse customers perceive they are the recipients of inequitable service and consequently experience low levels of satisfaction.

A reputation-based grid information service

In a large-scale wide-area system such as the Grid, trust is a prime concern. The current generation of grid information services lack the ability to determine how trustworthy a particular grid service provider or grid customer is likely to be. In this paper, we propose a grid information service with reputation management facility and its underlying algorithm for computing and managing reputation in service-oriented grid computing. Our reputation management service is based on the concept of dynamic trust and reputation adaptation based on community experiences. The working model and functionality offered by the proposed reputation management service is discussed.

Satisfaction, complaining behaviour and repurchase: an empirical study of a subscription service

The aims of this research were to examine the relationships between customer satisfaction, customer complaint behaviour, service recovery and the intention to repurchase in the Australian Pay TV industry. A survey of 171 respondents suggested that overall customer satisfaction was the main driver of the likelihood of disconnection from the Pay TV service. Those respondents who reported having a problem but not complaining directly about it were significantly more likely to have the intention to disconnect in the future than those who complained directly to their Pay TV service provider. However, there was no significant difference in terms of perceptions of overall satisfaction between those who had a problem and complained and those who had a problem and chose not to complain.
