The purpose of this paper is to analyze the impacts of Portfolio size effect due to scaling issues in the outcome obtained in a project portfolio selection for an electricity company in Brazil, focusing on improving business strategic performance.

The study uses a web-based decision support system (DSS), in which scaling issues are considered, incorporating results of previous work. The study evaluates 32 projects from the electricity company and compared the possible results when considering different scales. Additionally, a sensitivity analysis was conducted to analyze the robustness of the case, using the web-based DSS.

The results for an interval scale context showed a portfolio with 21 projects, contrasting with the correct solution of a portfolio containing 23 projects. The latter is related to a ratio scale context, with the proper transformation of weights, which was found to be robust with a sensitivity analysis using Monte Carlo simulation. This demonstrates that only appropriate models for selecting projects can improve the contribution to the company’s permanent strategies of increasing productivity, considering its constraints to achieve optimal results.

Additive value functions approach imposes certain requirements on the measurement scales used for the items in a portfolio that should not be ignored, once they have significant impact on the general portfolio results, which are directly related to the business strategic performance and the facilities of doing that with a web-based DSS.

The great difficulties which attach to the fixing of legal standards of composition for food products have now to be grappled with by the Departmental Committee appointed by the Board of Agriculture to consider and determine what regulations should be made by the Board, under Section 4 of the Sale of Food and Drugs Act, 1899, with respect to the composition of butter. As we predicted in regard to the labours of the Milk and Cream Standards Committee, so we predict now that the Butter Committee will be unable to do more than to recommend standards and limits, which, while they will make for the protection of the public against the sale of grossly adulterated articles, will certainly not in any way insure the sale of butter of really satisfactory, or even of fair, composition. Standards and limits established by law for the purposes of the administration of criminal Acts of Parliament must of necessity be such as to legalise the sale of products of a most inferior character, to which the term “genuine” may still by law be applied as well as to legalise the sale of adulterated and sophisticated products so prepared as to come within the four corners of the law. It is, of course, an obvious necessity that official standards and limits should be established, and the Board of Agriculture are to be congratulated upon the manner in which they are endeavouring to deal with these extremely knotty problems; but it is important that misconception on the part of the public and the trade with respect to the effect of the regulations to be made should be as far as possible prevented. All that can be hoped for is that the conclusions at which the Committee may find themselves compelled to arrive will not be such as to place too high and too obvious a premium upon the sale of those inferior and scientifically‐adulterated products which are placed in such enormous quantities on the food market.

This chapter traces the origin of racism and reviews the historical and contemporary debates around race and racialisation in western thought. There are persistent disagreements surrounding the origin and nature of racism. Because of the evolution of racist ideas, behaviours and institutional practices and policies, there are various views about the meaning and analytical application of racism. This chapter explores how ideas of race – understood as innate and immutable human differences that can be classified and ranked hierarchically based on race – has emerged in western history and evolved over time. It examines how this has influenced social and political practices and associated policies across the evolution of modernity. The chapter specifically discusses the Atlantic slave trade and how it shaped the historical development of race and racism within the context of colonialism. It concludes with a discussion and critical review of some of the racist systems and policies which have been enforced across different multiracial countries.
