Uma pesquisa sobre a opinião pública sobre incentivos financeiros para doação de óvulos no Brasil

Objective: The objective of this study was to assess the opinions of the Brazilian population about incentives for oocyte donation. Methods: A cross-sectional descriptive approach was used to consult the Brazilian public. The data collection involved the use of a structured questionnaire about legal and ethical issues surrounding oocyte donation. Individuals were randomly selected from the general population using different e-mail lists. Potential participants were contacted by e-mail and invited to participate in the study by completing an online web survey. Results: A total of 1,565 people completed the survey, including 1,284 women(82%) and 281 men(18%). Among the respondents, 1,309(83.6%) were university graduates, 1,033(66%) had a personal income ≥1,250 US dollars/month, 1,346(86%) considered themselves to be religious and 518 (33.1%) were health professionals. While many participants believed that women may donate their oocytes for altruistic reasons, the majority believed that a lack of oocyte donations is due to the prohibition of payments(64.3%) and that incentives would facilitate the decision to donate oocytes(84.7%). The majority of the participants(65.3%) agreed that a financial incentive(i.e., paying the donor) would be the most practical solution for increasing the number of oocyte donations. These results tended to be independent of gender, age, income, religion, education level and profession. Conclusion: While the Brazilian Federal Council of Medicine prohibits payments for oocyte donation, the majority of study participants had no objection to compensating oocyte donors. Moreover, most of the participants agreed that a financial incentive is the most practical solution to increasing the number of oocyte donations.

Bilevel approach for optimal location and contract pricing of distributed generation in radial distribution systems using mixed-integer linear programming

In this study, a novel approach for the optimal location and contract pricing of distributed generation (DG) is presented. Such an approach is designed for a market environment in which the distribution company (DisCo) can buy energy either from the wholesale energy market or from the DG units within its network. The location and contract pricing of DG is determined by the interaction between the DisCo and the owner of the distributed generators. The DisCo intends to minimise the payments incurred in meeting the expected demand, whereas the owner of the DG intends to maximise the profits obtained from the energy sold to the DisCo. This two-agent relationship is modelled in a bilevel scheme. The upper-level optimisation is for determining the allocation and contract prices of the DG units, whereas the lower-level optimisation is for modelling the reaction of the DisCo. The bilevel programming problem is turned into an equivalent single-level mixed-integer linear optimisation problem using duality properties, which is then solved using commercially available software. Results show the robustness and efficiency of the proposed model compared with other existing models. As regards to contract pricing, the proposed approach allowed to find better solutions than those reported in previous works. © The Institution of Engineering and Technology 2013.
