Scaling ideas in the theory of the quantum Hall effect are fundamentally based on topological principles in Anderson localization theory. These concepts have a very general significance and are not limited to replica field theory or disordered systems alone. In this chapter, we will discuss these ideas in several distinctly different physical contexts. We start with a brief overview that spans two and a half decades of experimental research on quantum criticality in strong magnetic fields. Secondly, we address the new understanding of universality that has emerged from the theory of Anderson localization and interaction phenomena. In the last part we show how the experimentally observed quantum phenomena fundamentally alter the way in which strong coupling problems in theoretical physics are perceived.

The essay investigates the phenomenon of laziness by first analyzing the opposition between laziness and the good. Both utility and the good make reference to labor. This opposition between labor and laziness is pivotal in Oblomov, Ivan Goncharov’s famous novel written in 1859. It marks a radical transition from a feudal paradigm to a capitalistic one. The two main characters in the novel are Ilya Ilyich Oblomov, a Russian, and Andrey Ivanovich Stolz, a German, who together seem to personify the contradiction between laziness and labor. But the purpose of the essay is to deconstruct that opposition. In this connection, one can cite Kazimir Malevich, who maintained that laziness is the Mother of Perfection and is always unconsciously inherent in the conscious intent to work. Analysis of the Latin concepts of otium and negotium indicates that the laziness/labor opposition may be deconstructed as a dialectic between labor and its opposite. In other words, laziness does not stand in contradiction to labor but is instead its inseparable dialectical other. In the last part of the essay, the article considers the thinking of Anatoly Peregud, a poet who spent almost all his life in a psychiatric hospital. According to Peregud, Lenin derived his pseudonym from the Russian linguistic root “len” (laziness) in order to make laziness central to communism. For his part, Lenin saw Oblomov as an emblem of the main obstacle standing in the way of communism.

One of the most impressive features of Anna Karenina is the way in which Tolstoy draws the reader's imagination beyond the literal level of the narrative into generalizations that seem mythical in a manner difficult to articulate. With Dostoevsky or Melville, one sees immediately a propensity for exploiting the symbolic value of things. With Tolstoy, things try, as it were, to resist conversion: they strive to maintain their “thingness” as empirical entities. A character in Dostoevsky is usually only half man; the other half is Christ or Satan. Moby Dick is obviously only half whale; the other half is Evil or some principle of Nature. But Anna Karenina is emphatically Anna Karenina. Like almost all of Tolstoy's characters, she has a proficiency in the husbandry of identity; she jealously hoards her own unique reality, so that it becomes difficult to say of her that she is a “type” of nineteenth-century Russian lady or a “symbol” of modern woman or an “archetypical” Eve or Lilith.

Artificial intelligence (AI) has continued to disrupt the way tasks are being carried out, finding its way into almost all facets of human existence, and advancing the development of human society. The AI revolution has made huge and significant inroad into diverse industries like health, energy, transport, retail, advertising, et cetera. AI has been found to assist in carrying out tasks more quickly and efficiently too. Tasks which were hitherto difficult have been simplified significantly through the use of AI. Slow adoption in judiciary has however been reported, compared to other sectors. A lot of factors have been attributed to this, with AI bias being an issue of concern. Decisions emanating from courts have a significant impact on an individual’s private and professional life. It is thus imperative to identify and deal with bias in any judicial AI system in order to avoid delivering a prejudiced and inaccurate decision, thereby possibly intensifying the existing disparities in the society. This paper therefore surveys judicial artificial intelligence bias, paying close attention to types and sources of AI bias in judiciary. The paper also studies the trust-worthy AI, the qualities of a trust-worthy artificial intelligence system and the expectations of users as it is being deployed to the judiciary, and concludes with recommendations in order to mitigate the AI bias in Judiciary.

Due to the continuous research and development activities taking place in almost all the disciplines, information overload and information explosion has occurred, which in turn poses a challenge to the user community to keep up with the knowledge in their discipline. The dynamic nature of information has forced the users to change the way of seeking information. Hence, there is an immediate need for the information professionals to update the services and facilities of the library. He/she should act as a ultimate search engine and satisfy the information needs of the users. This chapter highlights the changing approach to information by the user community in the present scenario and also provides the solutions to information professionals to tackle the information expectations of the users. This chapter has been written based on the observation of library users and the way they seek information for their business requirements and research and development activities.

This chapter claims to understand the implications of Cloninger´s psychobiological model of temperament in the people behaviour on social networking sites. This study uses secondary information as well as primary data. The author collected and analyzed an online survey with a sample of 365 individuals. The study contributed to bridging the research gap of the correlation between the Cloninger´s psychobiological model of temperament and people behaviour on SNSs. The main findings show that clear correlation exists between Cloninger´s psychobiological temperament dimensions and the way people interacts on Facebook. Mainly, temperament is affecting in almost all the areas that have been tested; Facebook affinity uses of Facebook, motives and barriers of using Facebook.

One of the concerns linked to ERP implementation is alignment. Indeed, ERP systems affect almost all business processes and even some strategic choices of a firm. That is why many studies focus on alignment concerns when studying ERP implementation. Nevertheless, firms are more and more interested in switching toward cloud ERP. This involves great challenges for business-IT alignment of an enterprise. Also, with cloud ERP, data and applications are provider-hosted. So, the way ERP is managed may be redefined and achieving alignment might be more challenging. Thus, this chapter aims to expose the major challenges and issues linked to ERP systems alignment. Some tendencies and best practices are also proposed for firms to overcome the alignment challenges, mainly in a cloud environment.

Feminist philosophy is philosophy that is aimed at understanding and challenging the oppression of women. Feminist philosophy examines issues that are traditionally found in practical ethics and political philosophy, metaphysics, epistemology and philosophy of language. In fact, feminist concerns can appear in almost all areas of traditional philosophy. Feminist philosophy is thus not a kind of philosophy; rather, it is unified by its focus on issues of concern to feminists. Feminist philosophers question the structures and institutions that regulate our lives. When Mary Wollstonecraft was writing in 1792, the institutions excluded and subordinated women explicitly. Wollstonecraft, as the title of her book (A Vindication of the Rights of Woman) makes clear, was extending the enlightenment idea that men have basic human rights, to women. Wollstonecraft argued that women should not be seen as importantly different from men: there may be differences due to different upbringing, but, Wollstonecraft argues, there is no reason to think men and women differ in important ways, and women should be given the same education and opportunities as men. What seemed radical in 1792 may not seem radical now. Yet gender inequality persists. Thus philosophers must look beyond the formal rules and laws to the underlying structures that cause and perpetuate oppression. The feminist philosopher is always asking, ‘is there some element of this practice that depends on gender in some way?’ Feminist philosophers examine and critique the way we structure our families and reproduction, the cultural practices we engage in, such as prostitution and pornography, the way we think, and speak and value each other as knowers and thinkers. In order to examine these issues the feminist philosopher may need an improved conceptual toolbox: we need to understand such complex concepts as intersectionality, false consciousness, and of course, gender itself. Is gender biologically determined – is it something natural and immutable, or is it socially constructed? As Simone de Beauvoir puts it, ‘one is not born, but rather becomes, a woman’. Feminist philosophers tend to argue that gender is all (or mostly) socially constructed, that it is something we invent rather than discover. Gender is nonetheless an important part of our world, and feminist philosophy aims to understand how it works.

Cosmology can mean many different things to different people. Sandage (1970) once described it as “the search for two numbers” (Ho and qo). At the other end of the spectrum, it may comprise almost all the interesting bits of astronomy and physics that bear on how the universe got to be the way it is. Supernovae can probe many of these bits because they are bright, have been going on for a long time, and contribute directly to the chemical and, perhaps, dynamical evolution of structure in the universe.
