Software ecosystems (SECOs) and open innovation processes have been claimed as a way forward for the software industry. A proper understanding of requirements is as important for SECOs as for more traditional ones. This article presents a mapping study on the issues of RE and quality aspects in SECOs. Our findings indicate that among the various phases or subtasks of RE, most of the SECO specific research has been accomplished on elicitation, analysis, and modeling. On the other hand, requirement selection, prioritization, verification, and traceability has attracted few published studies. Among the various quality attributes, most of the SECOs research has been performed on security, performance and testability. On the other hand, reliability, safety, maintainability, transparency, usability attracted few published studies. The article provides a review of the academic literature about SECO-related RE activities, modeling approaches, and quality attributes, positions the source publications in a taxonomy of issues and identifies gaps where there has been little research.

Usability is one of the most relevant quality aspects in Web applications. A Web application is usable if it provides a friendly, direct and easy to understand interface. Many Usability Inspection Methods (UIMs) have been proposed as a cost effective way to enhance usability. However, many companies are not aware of these UIMs and consequently, are not using them. A secondary study can identify, evaluate and interpret all data that is relevant to the current knowledge available regarding UIMs that have been used to evaluate Web applications in the past few decades. Therefore, we have extended a systematic mapping study about Usability Evaluation Methods by analyzing 26 of its research papers from which we extracted and categorized UIMs. We provide practitioners and researches with the rationale to understand both the strengths and weaknesses of the emerging UIMs for the Web. Furthermore, we have summarized the relevant information of the UIMs, which suggested new ideas or theoretical basis regarding usability inspection in the Web domain. In addition, we present a new UIM and a tool for Web usability inspection starting from the results shown in this paper.

Two issues were raised in the article entitled „Dishes at Nasidien’s feast (Horatius, Saturae II 8) and Apicius’ De re coquinaria”. First, comparison of dishes the description of which Horace included in Saturae II 8 with heir analog­ical recipes for these from Apicius’ De re coquinaria. These comparisons lead to the conclusion that, even in Augustan times, developing the culinary art had its supporters and that the chefs were trying to surprise symposium participants with new ideas, which made them experiment in this area all the time. An example of such efforts, among the others, is the method of making a sauce which was used to put on Nasidien’s moray, or wild pigeons whose croups had been cut off. On the other hand, on the example of De re coquinaria we can observe the evolution of culinary art which attached more and more importance to various kinds of spices used in more and more sophisticated sauces which gave a proper taste to diverse dishes of fish, poultry and game. The other issue, which is still present, is proper understanding and interpretation of these fragments of Horace’s Saturae II 8 where the poet gives us a description of dishes prepared by Nasidien’s chefs. Among the others, attention was drawn to the fact that the notion of faecula Coa (Saturae II. 8. 9) shall not be understood, as assumed before, as dried powdered yeast or wine grounds but rather as a substitute for grape honey described by Isidor (Etymologiae XX 3, 13: „Faecula uva pinguis, decocta usque ad crassitu­dinem mellis, ac refrigata, utilis stomacho”). This understanding of faecula Coa lets us read differently 6-9 verses in Saturae II 8 where the wild boar served by Nasidien was poured over by cheap substitutes, i.e. so called allec sauce (instead of liquamen) and faecula Coa (instead of honey). The Horace’s description, thus, has, in this place an ironic implication. It was also suggested that the 51-53 verses in Saturae II 8, where Nasidien boasts that he was the first one with the idea of boiling eruca sativa (rucola) with inula helenium, should be linked with previous verses which give the description of the sauce used for pouring over moray as eruca sativa boiled with inula helenium did not form a new dish but it was an ingredient of the mentioned sauce. Information about liver of a white goose fed with figs in Saturae II 8, 88 deserves special attention. We cannot find this dish recipe in Apicius’ De re coquinaria. However, we learn from the Plinius’ account that it was Apicius who invented a new method of preparing goose liver (Plinius, Historia naturalis VIII 209: Adhibetur et ars iecori feminarium sicut anserum, inventum M. Apici, fico arida saginatis ac satie necatis repente mulsi potu dato). This method involved feeding those birds with figs before they were killed. This way ensured that goose liver had a right taste and later wine with honey was add­ed to it. However, according to Horace’s information, which cannot be shaken, the custom of feeding geese with figs had been known before Apicius. As, on the basis of preserved records on Apicius’ life, it is difficult to confirm that he lived in Horace’s times it seems necessary to correct the account of Pilnius and to interpret it in the way that the innovation of Apicius involved only serving liver with some wine with honey (muslum), not feeding geese with figs as this practice had been done much earlier.

This article relates relevant aspects of business: logistics, innovation, female participation and multicriteria models. One issue that is paying close attention is the participation of women in different social spheres, including business. On the other hand, logistics is related to practically all areas of an organization, which can be visualized, when studying it supported, in the Logistics Model Based on Positions (MoLoBaC). There are other models that interest this work, such as multicriteria models, in particular the multiattribute models with multiplicative factors (MMcFm). Also, companies maintain and prosper thanks to their ability to manage innovation. The confluence of these four fields of knowledge generates the general objective of this research: Use of the different areas of the logistics model based on positions to measure, through a multiattribute model, the female participation in logistics, having as a thread the innovation processes.

This chapter examines Plato’s views on theology. Plato inherited Socrates’s conviction that a proper understanding of the divine nature is essential to human virtue and happiness. Hence, god’s essential goodness is the thesis that runs most prominently through all his theological arguments. Since this supreme goodness is manifested above all in the cosmic structures created by divine intelligence, it is understandable if Plato turns out to stick resolutely to his insistence that, for all its appearances of imperfection, from a global perspective ours is the best physical world that could ever have been created, even by a supremely powerful being. On the other hand, Plato shows less interest than Socrates did in the idea of divine intervention in individual human lives. To that extent his work in theology points forward to Aristotle, who would insulate god entirely from concern with the sublunary world.
