A Internet é uma tecnologia que revolucionou o mundo, criando novas formas de interação entre pessoas, organizações e negócios. O setor hoteleiro é um segmento que muito tem se beneficiado dos serviços suportados pela Internet. O objetivo do estudo é identificar os diferentes fatores que influenciam ao uso da Internet sob três dimensões: individual, organizacional e ambiental. Um modelo conceitual foi postulado contendo nove variáveis independentes sobre duas variáveis dependentes, relativas ao padrão de uso da Internet. Os dados foram coletados junto a 52 hotéis localizados no litoral do Recife – PE. O resultado da análise inferencial dos dados mostrou um padrão diferenciado de uso da Internet nos hotéis de pequeno, médio e grande porte e como os fatores acima descritos podem ser mais bem explorados a fim de se atingir um eficiente padrão de uso, aumentando suas posições competitivas. Baseadas na análise e resultados obtidos do estudo, são esboçadas algumas recomendações e implicações para futuras pesquisas. ABSTRACT:The Internet technology has revolutionized the world, creating new forms of interaction among people, organizations and businesses. The hotel sector has reaped many benefits from services supported by the Internet. The object of this study is to explore different factors that influence the adoption of the Internet in three areas: individual, organizational and environment. A conceptual framework was advanced containing nine independent variables and two dependent variables related to the usage of the Internet. Data was collected from 52 hotels located along the coast of Recife, PE, Brazil. Analysis of the data has demonstrated the Internet use in small, medium and large size hotels. Some attributes of the Internet usage could be better utilized by owners and managers in order to achieve a more efficient pattern of use, improving their competitive position. Based on the findings obtained from the study, some recommendations and implications for future research are advanced

The state of Rio Grande do Norte presents a great potentiality for the production of ceramic tiles because of having natural raw material in quantity and quality making its economical exploration possible, beyond the great energetic differential of the state, the natural gás. This works aims to study the influence of the dolomite and granulometry concentration and calcinations temperature in the obtaining of formulations for porous coverings which have to be coherent to the project,s specifications. The experiments have involved the physical-chemical and mineralogical characterizations of raw materials and mechanical tests in the dry and burnt proof bodies preceding a mixture experiment planning with the use of the response surface methodology, in order to get the best raw materials combinations to produce a ceramic mass with specific properties. The twelve ceramic masses studied in this work were prepared by the via dry process, characterized, shaped by uniaxial pressing and sinterized in the temperatures of 940ºC, 1000ºC, 1060ºC, 1120ºC and 1180ºC, using a fast burning cycle. The crystalline phases formed during the sintering in the temperatures in study have revealed the presence of anorthite and diopside beyond quartz with a remaining phase. These phases were the main responsible ones by the physical- mechanical properties of the sinterized proof bodies. The proof bodies after the sintering stage have presented water absorption higher than 10% and a good dimensional stability in all studied temperatures. However, the flexural breaking strength results in the temperatures of 940ºC, 1000ºC and 1060ºC, under the temperature zone of the vitrification of ceramic whiteware do not reach the flexural breaking strength specific for the porous wall tile (15 MPa), but in the temperature of 1120ºC next to the vitrification temperature zone, some whiteware ceramic (formulations) has reached the specified value for the porous wall tile. The results of this work have showed that the studied raw materials have great importance for used in the production of porous wall tiles (BIII)
