Abstract: objectives: to compare surgical morbidity and time, as well as anatomical outcomes between vaginal histerectomy and uterine preservation in the treatment of uterine prolapse using a mesh kit (nazca ?). methods: randomized controled trial with 31 women with uterine prolapse pop-q stage 3 or 4 pelvic organ prolapse who underwent vaginal surgery using tipe i polypropilene mesh (nazca ?). they were randomized in two groups: group hv: hysterectomy and pelvic reconstruction floor with mesh (n=15); group hp: hysteropexy and pelvic reconstruction floor with mesh (n=16). race, miccional urgency, intestinal constipation, sacral pain were assessed as well as the amount of bleeding and time of operation. results: median follow-up was nine months on both groups. no difference was observed on complication rates and functional outcomes. operation time was 120 minutes on group hv, versus 58.9 minutes on group hp (x2 = 17.613*, p < 0.001 ) and intraoperative blood loss was 120 ml on group hv versus 20 ml on group hp (x2 = 19.425*; p < 0.001). there was no differences in relationship to anatomical cure rates. objective success rate was 86.67% to group hv and 75% to group hp (p=0,667) at nine months of follow-up. the anatomical results were similar between the two groups. conclusion: the anatomic results between histeropexy and hysterectomy were similar. however, surgical time and blood loss were greater in group with histerectomies. the erosion rate were also similar. vaginal surgery using mesh is an effective procedure for pelvic organ prolapse.

Abstract: RESUMO Assim como diversas outras organiza es de servi os, algumas institui es de ensino superior investem em propaganda impressa para atrair candidatos para seus cursos. A literatura sobre comunica o de servi os sugere que a utiliza o de estímulos como fotografias das instala es e testemunhais de alunos e ex-alunos s o formas de tangibilizar a oferta como de servi os t o fortemente intangíveis quanto os educacionais. Neste trabalho, é investigado o impacto de dois tipos de argumento usados em anúncios de servi os educacionais, sobre as atitudes do público de institui es de ensino superior. A defini o dos dois tipos de argumento foi feita com base no “paradigma das pistas”, cue paradigm (OLSON; JACOBY, 1972). Os argumentos usados foram fotografias das instala es (uma pista intrínseca, segundo o paradigma das pistas) e testemunhos de alunos (uma pista extrínseca). Foi conduzido um experimento para avaliar n o apenas o efeito dos quatro níveis de tipo de argumento (ausência de pistas, somente intrínsecas, somente extrínsecas, intrínsecas e extrínsecas combinadas) sobre atitudes do público, mas também o efeito do nível de envolvimento do público com institui es de ensino em cada uma das quatro condi es do experimento. Resultados mostram que, embora n o tenham sido detectadas diferen as entre efeitos dos quatro tipos de argumento sobre atitudes dos públicos, os respondentes com baixo nível de envolvimento na dimens o valores/auto-imagem demonstraram atitudes mais favoráveis em rela o à inten o de matrícula quando expostos a testemunhal (pista extrínseca). ABSTRACT Just like other services organizations, some higher education institutions have invested in printed advertising to attract applicants. The services management literature suggests that using stimuli such as pictures of the facilities and alumni testimonials may help to turn tangible the offer of services so strongly intangible as higher education. In the present work, the impact of two different types of cue on prospects’ attitudes is investigated. The cue paradigm (Olson & Jacoby 1972) has been used to select the two types of cue: intrinsic (facilities pictures), and extrinsic (testimonials). An experiment has been conducted not only to assess the effect of the impact of four levels of presence of cues (absent, only intrinsic, only extrinsic, both) on prospects’ attitudes, but also the effect of prospects’ involvement level with higher education organizations on each of the four conditions. Results show that although there were no differences detected between the effects of four types o
COMPARING PERCEPTIONS OF SERVICE QUALITY IN BRAZIL AND UK

Abstract: This paper investigates whether the SERVPERF model developed by Cronin andTaylor (1992) can be applied in the same industry (retail banks) in two different countriesBrazil and UK. We find differences between the countries in the perception of the serviceprovided by retail banks. We also find differences between the countries in the relationshipbetween the service provided and (i) the overall perception of service quality, (ii) customersatisfaction and (iii) future purchase intentions. Factor analysis of the data identified differentdimensional structures for Brazilian and British samples. The Brazilian sample presentsalmost the same structure of Parasuraman et alii (1988) SERVQUAL. The UK samplepresented a different three-factor dimensional structure which shows that the dimensionalstructure does not travel well into other cultures.Also, as this study stands, the differencesfound between the two samples cannot yet be attributed to cultural differences between UKand Brazil. These differences may be related to the service provided by the banks.
CDS Evaluation Model with Neural Networks  [PDF]
Eliana Angelini, Alessandro Ludovici

Abstract: This paper provides a methodology for valuing credit default swaps (CDS). In these financial instruments a sequence of payments is promised in return for protection against the credit losses in the event of default. Given the widespread use of credit default swaps, one major concern is whether the credit risk has been priced accurately. Credit risk assessment of counterparty is an area of renewed interest due to the present financial crises. This article proposes a non parametric model for estimating pricing of the CDS, using learning networks, based on the structural approach pioneered by Merton [1] as regards the independent variables; he proposed a model for as-sessing the credit risk of a company by characterizing the company’s equity as a call option on its assets. The model that we are introducing turns out peculiar not only for the use of the neural network, but also for the use of the implied volatility of one-year options written on the shares of the analyzed companies, instead of historical volatility: this leads to a higher capability of getting the signals launched by the market about the future creditworthiness of the firm (historic volatility, being a medium value, brings in temporal lags in the evaluation). Besides, our analysis differs from the structural approach for the fact that it considers the 30-month mean-reverting historical series for CDS spreads, and this turns out to be one of the main advantages of our forward-looking model.
Between two worlds: an ethnographic study of gay consumer culture in Rio de Janeiro

Abstract: it is not easy to study socially marginalized groups such as gays, ethnic minorities, and others. this is, however, an extremely relevant topic in the consumer behavior area since the status of members of a modern consumer society is largely denied to stigmatized social groups (barbosa, 2006). the objective of this work is to shed light on how gay men in rio de janeiro use the discourse associated with their possessions to build and maintain the symbolic and hierarchical boundaries between the gay and heterosexual worlds, as well as to investigate the role consumption plays in this boundary setting. an ethnographic observation of a group of gay men in rio de janeiro was conducted, along with 20 semi-structured interviews with openly gay men between 2005 and 2008. the results suggest that: (a) the world culturally built by gays seems to be divided into a gay world and a heterosexual world, where the division between these two worlds not only happens in their minds, but also in their possessions and purchasing decisions; (b) the meaning of gay mens' places of consumption range from profane to sacred along their lives; and (c) in the gay world, the body is seen both as a cultural construction and as an asset.
