Abstract Strength, softness, and absorbency have been identified as the key attributes for disposable consumer products such as tissue, towel and diapers. These attributes are generally evaluated subjectively by users. Although subjective evaluation may be necessary for developing such consumer products, it is time-consuming and expensive. More importantly, it seldom provides guidance or direction regarding process control or product development. The main reason is because subjective evaluation is performed after the fact (ex post facto), not before the event (not ex ante). Accordingly, it has been desirable to develop physical test methods to predict in-use performance of a consumer product. In developing physical test methods to link with subjective evaluation, reliable and relevant subjective data is necessary. Developing physical test methods for softness of hygiene paper has been extremely challenging. The objective of this paper is to demonstrate a feasibility of developing physical test methods which can be highly related to subjective evaluation. To this end, it is hypothesized that tissue softness mainly consists of bulk softness and surface softness. It is assumed that the bulk softness should be determined from bulk stiffness which is defined as the slope between the two specified points in a load-elongation curve from tensile testing. It is also assumed that the surface softness should be determined from the surface properties (roughness and friction) from a surface tester (e. g., Model: KES-SESRU. Kato Tech, Japan). It is suggested that the principles used here for developing physical test methods for tissue softness should be also applicable to other physical properties such as strength and absorbency.

Este artigo apresenta um estudo de caso ex-post-facto do projeto Sustainability Maker Brazil, onde foi possível analisar criticamente a participação de uma empresa do setor moveleiro com relação às práticas e às diretrizes da pro­dução distribuída. Para tanto, além de uma Revisão Bibliográfica Sistemática através da qual foi possível conhecer e esta­belecer estas práticas e diretrizes, também foram analisados os relatórios do projeto SuM/BR e suas referentes etapas no desenvolvimento de um novo produto. Como resultado, é possível observar que o Crowd-Design pode ser considerado como uma opção para a produção distribuída.ABSTRACT This paper presents an ex-post-facto study case made at Sustainability Maker Brazil's project. It was possible to critically analyze the participation of a furniture company with regard to practices and guidelines of distributed production. To this end, in addition to a Systematic Literature Review through which it was possible to meet and establish these practices and guidelines, were also analyzed the SuM/BR project reports and know the product development phases. As a result, it is possible to observe that the Crowd-design can be considered as an option for distributed production.

The issues of entrepreneurial ex-ante determination and managerial intent are discussed as applied to the ex-post organizational result. Possible errors in over-attribution of success to the celebrity-entrepreneur and the tendency to disregard the impact of endogenous market conditions, randomness on success due to creative destruction free-market mechanisms are discussed.Humans inherently look for correlation as correlations produce useful knowledge. Specifically, investors seek to create cause-effect knowledge in order to enhance returns. Students and researchers of business also attempt to tie causation to effects. Fundamental attribution error psychology posits a tendency to over-weight personality-based explanations and under-value situational factors when assessing what factors are responsible for the ex-post-facto outcome of an organization. In the field of entrepreneurship, this trait of human psychology may manifest in the tendency to credit the leader him/herself of a successful organization vis-a-vis more important external factors which contributed to success such as the temporal status of market demand conditions.The existence of fundamental attribution error may likewise lead to over-weight emphasis of a leaders input to organizational failure, however, the sample of entrepreneurs linked to successful organizations is self-selected as the unsuccessful entrepreneurs are usually not locatable. Therefore, stakeholders show strong tendencies to link the focus-entrepreneur with a resultant successful enterprise. This tendency is observable in the general culture as most students of entrepreneurship believe the knowledge and actions of Ray Kroc were a prime factor in the economic success of McDonalds. The question explored within the present study is to what extent is such ex-post-facto success attributable to the ex-ante entrepreneurial intent appropriate?Most people familiar with business strongly identify; Steve Jobs with Apple, Thomas Watson with IBM, Dave Thomas with Wendys, Bill Gates with Microsoft, Howard Schultz with Starbucks, Harland Sanders with KFC, and Fred Smith with FedEX. Instructors of entrepreneurship teach with these stories. More importantly, researchers of entrepreneurship use these leaders and their associated knowledge and behavior as independent variables when regressing these variables onto the ex-post dependent outcome of the organization. The investing and finance community also correlate these success story celebrity-entrepreneurs with the resulting rate of return on equity. This paper explores a series of archive-based recollections of the entrepreneurs ex-ante thoughts to demonstrate that many legendary-business entrepreneurs did not expect the organizations extraordinary rates of growth and the ex-post-facto market successes. Hence, cause-effect attribution questions arise.One important research question addressed within is; if the entrepreneur did not know of, or expect growth before the growth, then the resulting growth may not be fully attributed to the person as valid intent. More generally, then to what extent can the resulting organizational success be attributed to the identified behavior of entrepreneurship? Are the successes normally attributed to individual-entrepreneurs really organizational successes or even random-walk phenomenon? Are fundamental attribution errors over-weighing the construct of entrepreneurship and obscuring other, organizational-based, effective causes of economic success?The rise of the media-driven, celebrity-entrepreneur leads to a recent strengthening of attribution of organizational success to that leader. Conclusions within the current study lead to a more distinct focus on the time-limited tasks of entrepreneurship that are very limited in proportional impact to a firms total life-span and resulting economic value. We then can attribute much more of the resulting economic value to the impact of organizational dynamics and organizational development.

<p>This study seeks to determine the impact of sales promotions on sales turnover in the airlines industry in Nigeria. Ex post facto and survey research design were adopted. Secondary data on average monthly passenger turnover covering a period of 25 years (1991-2015) were collected from the records of airport authority. A questionnaire was also administered to 450 air travellers to ascertain the extent to which sales promotions incentives stimulate them to travel by air within Nigeria. Frequency analysis, regression and t-Test methods of analysis were applied. The results show that sales promotions incentives significantly impacted sales turnover in the airlines industry; and air travellers prefer non-monetary sales promotional offers and off-line incentives to monetary and online offers. The study, therefore, recommends that the management of the airlines need to be more innovative in making promotion offers to air travellers so as to optimize the opportunity. Non-monetary and offline incentives offerings should be emphasized to meet the preference of air travellers. For future research, the study suggests that the focus can be on identifying other salient factors that motivate passengers to travel by air so as to boost industry sales.</p>

This chapter explores the relationship between private law and common law. Both private law and the common law fit awkwardly into the dominant theoretical models of law, which emphasize regulation and social control by the state. Thus, the common law has long been criticized for failing to comply with the model of clearly articulated rules that are announced ex ante and applied ex post. The private law, for its part, contains numerous features that make it a poor candidate for a well-designed regulatory regime. The chapter then argues that developments in private law theory suggest a convergence between private law and the common law that responds to these issues, rendering the law both intelligible and providing an answer to the common objection that the common law involves ex post facto lawmaking. In addition, a recovery of this classical common law theory is both conceptually feasible and offers solutions to problems left currently unanswered by neoformalism.

“This is an evaluation of the therapeutic effect of sex reassignment surgery on 36 female-to-male transsexuals and 105 male-to-female transsexuals in the Netherlands. Data were collected by means of structured interviews. The evaluation was made on the basis of subjective data only, that is on what the persons themselves reported on their gender identity, gender role, and physical condition. Allowing for the restrictive methodology of the (ex post facto) study, it is concluded that there is no reason to doubt the therapeutic effect of sex reassignment surgery. No specific differences were found between those who were still in medical treatment and those who had completed treatment. The findings obtained in the female-to-male transsexuals compare favourably with those obtained in male-to-female transsexuals. Finally, the conclusion is drawn that more attention ought to be paid to psychosocial guidance in addition to medical guidance.”
