The present chapter is intended as a lightweight introduction to ubiquitous computing as a whole, in preparation for the more specific book parts and chapters that cover selected aspects. This chapter thus assumes the preface of this book to be prior knowledge. In the following, a brief history of ubiquitous computing (UC) is given first, concentrating on selected facts considered as necessary background for understanding the rest of the book. Some terms and a few important standards are subsequently mentioned that are considered necessary for understanding related literature. For traditional standards like those widespread in the computer networks world, at least superficial knowledge must be assumed since their coverage is impractical for a field with such diverse roots as UC. In the last part of this chapter, we will discuss two kinds of reference architectures, explain why they are important for the furthering of Ubiquitous Computing and for the reader’s understanding, and briefly sketch a few of these architectures by way of example.

Public maritime law dealing with safety issues is mostly recognised as a contemporary branch of maritime law. In contrast to public maritime law, the history of private maritime law referred to as shipping law is very well described in related literature. But also maritime safety arrangements can be found in the ancient as well medieval collections of laws. Article aims to analyse the ancient roots of contemporary legal institutions referring to maritime safety law.

The paper concerns the ideological profile of urban movements in Poland. In the first part, the author definesthe concept of urban movement based on the related literature and outlines the history of the urban matterin Poland. Then, attempts are made to reconstruct the ideological profile of urban activism. This is done onthe basis of an analysis that includes the main ideas to which urban activists refer (right to the city, idea ofparticular narratives, city-view) as well as the urban theses that include the postulations developed by theCongress of Urban Movements being the effect of consolidation activities in the Polish urban movements’environment. In conclusion, the key groups of postulations formulated by activists in Polish cities are analysedthrough the perspective of the views contained in the main contemporary political doctrines.

AbstractA group K is said to be a B-group if every permutation group containing K as a regular subgroup is either imprimitive or 2-transitive. In the second edition of his influential textbook on finite groups, Burnside published a proof that cyclic groups of composite prime-power degree are B-groups. Ten years later, in 1921, he published a proof that every abelian group of composite degree is a B-group. Both proofs are character-theoretic and both have serious flaws. Indeed, the second result is false. In this paper we explain these flaws and prove that every cyclic group of composite order is a B-group, using only Burnside’s character-theoretic methods. We also survey the related literature, prove some new results on B-groups of prime-power order, state two related open problems and present some new computational data.

With respect to African Americans, the history of racial discrimination in the imposition of the death penalty is well-known, and the persistence of racial disparities in the modern era of capital punishment is well-documented. In contrast, the influence of Latino ethnicity on the imposition of the death penalty has been studied very little. A review of the limited literature reveals evidence of discrimination against Latinos. Archival studies generally find ethnicity-of-victim discrimination, and some of those studies find ethnicity-of-defendant discrimination disadvantaging Latino defendants; these findings parallel the findings of the much more robust literature investigating bias against African American defendants and victims. The controlled experimental studies generally show both ethnicity-of-defendant and ethnicity-of-victim discrimination disadvantaging Latinos. Related literature investigating stereotypes, animosity, and discrimination in other criminal justice decisions further suggests the likelihood of ethnicity discrimination in the imposition of capital punishment, as well as the need for further research.

Although peer prediction markets are widely used in crowdsourcing to aggregate information from agents, they often fail to reward the participating agents equitably. Honest agents can be wrongly penalized if randomly paired with dishonest ones. In this work, we introduce selective and cumulative fairness. We characterize a mechanism as fair if it satisfies both notions and present FaRM, a representative mechanism we designed. FaRM is a Nash incentive mechanism that focuses on information aggregation for spontaneous local activities which are accessible to a limited number of agents without assuming any prior knowledge of the event. All the agents in the vicinity observe the same information. FaRM uses (i) a report strength score to remove the risk of random pairing with dishonest reporters, (ii) a consistency score to measure an agent's history of accurate reports and distinguish valuable reports, (iii) a reliability score to estimate the probability of an agent to collude with nearby agents and prevents agents from getting swayed, and (iv) a location robustness score to filter agents who try to participate without being present in the considered setting. Together, report strength, consistency, and reliability represent a fair reward given to agents based on their reports.

Krebs's unusual monograph demonstrates that the writing of pure music theory remains an essential enterprise—particularly in the relatively neglected rhythmic domain—but only if the reader undertakes active reading and has prior knowledge of how the music goes. Within the monograph, perpetuation of the image of the misunderstood and suffering artist as a clue to the extramusical meaning Schumann associated with metrical dissonance leads to biased results. This essay's supplementary analysis of the first movement of Schumann's Symphony No. 3, informed by the history of ideas, proposes that in this movement metrical dissonance is used to reinterpret an emblem of the past so as to convey a vision of the future.

This article is entitled “Nurcholish Madjid and Harun Nasution”, two Indonesian figures and Islamic thinkers who had strong and broad influences in the history of Islamic intellectualism in Indonesia. Their thinking broadly impacted various aspects of the Islamic life in Indonesia, especially in education, their ideas supported a variety of related literature and even became a reference and orientation for Indonesian Muslim intellectuals. One proof of the strong influence of Cak Nur is that he succeeded in developing intellectual discourse among Islamic societies in a modern, open, and democratic way. Likewise is the mindset developed by Harun Nasution, a contemporary Islamic theologian characterized by rational thinking. Abstrak: Artikel ini berjudul Nurcholish Madjid dan Harun Nasution yang merupakan dua tokoh Indonesia sekaligus pemikir Islam yang mempunyai pengaruh kuat dan luas dalam sejarah intelektualisme Islam yang ada di Indoneia. Pemikirannya membawa dampak yang amat luas dalam kehidupan keagamaan Islam di Indonesia dari bergagai kalangan, terutama sekali dalam dunia akedemisi karena berbagai gagasan dari meraka menjadi pendukung dalam berbagai literature yang berkaitan, dan lebih dari itu ia bahkan menjadi rujukan serta kiblat kaum intelektual Muslim Indonesia.

Recurring themes and traditions within the biblical corpus have attracted much scholarship. This article uses P. T. Anderson’s Magnolia (1999) as a test case for the ways traditions may or may not interact, and what that means for ‘tradition history.’ While the film has many features which strike many viewers as biblical, the author-director denies prior knowledge of these connections. The film is analyzed in terms of structure, Anderson’s claimed sources, the American cultural context of the 1990s, and its biblical resonances. After assessing the import of these observations, the tradition history of Magnolia is compared to the tradition history of the exodus in the Hebrew Bible. Within the framework of attention to media contexts, the article concludes by noting the importance of authority, canon, and multiple lines of transmission. In so doing, our understanding of the transmission of traditions is problematized, and a broader, less text-centric paradigm is called for.

Subject. This article examines whether there is a dependence of the leveraged buyout returns on the transaction strategy. Objectives. Based on the refinement of leveraged buyout (LBO) strategies, the article aims to analyze their impact on the profitability of financial sponsors and identify trends in the development of leveraged buyout transactions. Methods. For the study, I used the methods of correlation analysis, comparison, the abstract-logical method, and a subject-related literature review. Results. Based on the analysis of data on public-private LBOs completed in the period from 1996 to 2018, the article determines the dependence of the leveraged buyout efficiency on the applied LBO strategy and tactics of cash flow allocation in the LBO process. The article emphasizes the importance of the company's full history of cash flows to and from the LBO sponsor not only during the transaction period, but until its actual completion, as well, to analyze the LBO returns. The article also shows the trends in the development of LBO transactions. Relevance. The results of the study can contribute to a deeper understanding of the factors affecting the level of LBO transaction profitability, and the further development of business acquisition leveraged transactions.
