The objective of this paper is to prove that the sea wave height is not a Gaussian process. This is contrary to the common belief, as the height of a sea wave is generally considered a Gaussian process. With this aim in mind, an empirical study of the buoys along the US coast at a random day is pursued. The analysis differs from those in the literature in that we study the Gaussianity of the process as a whole and not just of its one-dimensional marginal. This is done by making use of random projections and a variety of tests that are powerful against different types of alternatives. The study has resulted in a rejection of the Gaussianity in over 96% of the studied cases.

This chapter assesses the accusation that immigrants, particularly undocumented immigrants, take advantage of societal resources at the expense of native-born citizens. Between 2002 and 2009, immigrants paid an estimated $115.2 billion more into Medicare than they used. Meanwhile, a 2018 Health Affairs study used data from the Medical Expenditure Panel Survey (MEPS) to measure both premiums and expenditures from private health insurance. Both documented and undocumented immigrant groups had positive net contributions, meaning they paid more toward their private insurance coverage than they spent in receiving health services. In contrast, US natives had a negative net contribution, meaning that, per capita, their expenditures on health care were greater than their premiums. Thus, these findings upend the common belief that immigrants are a drain on the US health care system. In reality, immigrants who contribute to Medicare and to private health insurers are subsidizing the health care of US citizens.

There has been a common belief that the presence of classical Chinese elements may be an important characteristic of the written style in modern Chinese. An empirical study employing the multi-feature, multi-dimensional framework for studying register variation (Biber 1988) and the statistical method of correspondence analysis confirms that there is indeed a classical dimension in modern written Chinese; but it is only one of two dimensions. The quantitative results further show that the classical dimension is not the primary dimension. The more important dimension is that of ‘literate vs. non-literate’, which has not received as much attention. The separation of the classical from the literate dimension makes it possible to account for the fact that registers having more classical Chinese elements are not necessarily more literate and vice versa. Another intriguing finding from the study is that classical Chinese elements are not monolithic; there seem to be four different types, which are distributed differently along the literate as well as the classical dimension. The difference in word length and integrability is hypothesized to account for the different types.

Non-replicating bacteria are known to be (or at least commonly thought to be) refractory to antibiotics to which they are genetically susceptible. Here, we explore the sensitivity to killing by bactericidal antibiotics of three classes of non-replicating populations of planktonic bacteria; (1) stationary phase, when the concentration of resources and/or nutrients are too low to allow for population growth; (2) persisters, minority subpopulations of susceptible bacteria surviving exposure to bactericidal antibiotics; (3) antibiotic-static cells, bacteria exposed to antibiotics that prevent their replication but kill them slowly if at all, the so-called bacteriostatic drugs. Using experimental populations of Staphylococcus aureus Newman and Escherichia coli K12 (MG1655) and respectively 9 and 7 different bactericidal antibiotics, we estimate the rates at which these drugs kill these different types of non-replicating bacteria. Contrary to the common belief that bacteria that are non-replicating are refractory to antibiotic-mediated killing, all three types of non-replicating populations of these Gram-positive and Gram-negative bacteria are consistently killed by aminoglycosides and the peptide antibiotics, daptomycin and colistin, respectively. This result indicates that non-replicating cells, irrespectively of why they do not replicate, have an almost identical response to bactericidal antibiotics. We discuss the implications of these results to our understanding of the mechanisms of action of antibiotics and the possibility of adding a short-course of aminoglycosides or peptide antibiotics to conventional therapy of bacterial infections.

American Catholicism has long adapted to US liberal institutions. Progressive Catholicism has taken the liberal values of democratic participation and human rights and made them central to its interpretation of Catholic social teaching. This chapter explores in detail the thought of David Hollenbach, S.J., a leading representative of progressive Catholicism. Hollenbach has proposed an ethical framework for an economy aimed at the common good, ensuring that the basic needs of all are met and that all are able to participate in economic life. The chapter also looks at the US Catholic bishops’ 1986 pastoral letter Economic Justice for All, which emphasizes similar themes while also promoting collaboration between the different sectors of American society for the sake of the common good.

This commentary discusses three challenges for the promising and ambitious research agenda outlined in the volume. First, it interrogates the volume’s attempts to differentiate political communities of legitimation, which may vary widely in composition, power, and relevance across institutions and geographies, with important implications not only for who matters, but also for what gets legitimated, and with what consequences. Second, it examines avenues to overcome possible trade-offs from gains in empirical tractability achieved through the volume’s focus on actor beliefs and strategies. One such trade-off is less attention to evolving norms and cultural factors that may underpin actors’ expectations about what legitimacy requires. Third, it addresses the challenge of theory building that can link legitimacy sources, (de)legitimation practices, audiences, and consequences of legitimacy across different types of institutions.

This work challenges the common belief that Aristotle’s virtue ethics is founded on an appeal to human nature, an appeal that is thought to be intended to provide both substantive ethical advice and justification for the demands of ethics. It is argued that it is not Aristotle’s intent, but the view is resisted that Aristotle was blind to questions of the source or justification of his ethical views. Aristotle’s views are interpreted as a ‘middle way’ between the metaphysical grounding offered by Platonists and the scepticism or subjectivist alternatives articulated by others. The commitments implicit in the nature of action figure prominently in this account: Aristotle reinterprets Socrates’ famous paradox that no one does evil willingly, taking it to mean that a commitment to pursuing the good is implicit in the very nature of action. This approach is compared to constructivism in contemporary ethics.

Numerous claims have been made by a wide range of commentators that punk is somehow “a folk music” of some kind. Doubtless there are several continuities. Indeed, both tend to encourage amateur music-making, both often have affiliations with the Left, and both emerge at least partly from a collective/anti-competitive approach to music-making. However, there are also significant tensions between punk and folk as ideas/ideals and as applied in practice. Most obviously, punk makes claims to a “year zero” creativity (despite inevitably offering re-presentation of at least some existing elements in every instance), whereas folk music is supposed to carry forward a tradition (which, thankfully, is more recognized in recent decades as a subject-to-change “living tradition” than was the case in folk’s more purist periods). Politically, meanwhile, postwar folk has tended more toward a socialist and/or Marxist orientation, both in the US and UK, whereas punk has at least rhetorically claimed to be in favor of “anarchy” (in the UK, in particular). Collective creativity and competitive tendencies also differ between the two (perceived) genre areas. Although the folk scene’s “floor singer” tradition offers a dispersal of expressive opportunity comparable in some ways to the “anyone can do it” idea that gets associated with punk, the creative expectation of the individual within the group differs between the two. Punk has some similarities to folk, then, but there are tensions, too, and these are well worth examining if one is serious about testing out the common claim, in both folk and punk, that “anyone can do it.”

This article engages with how religion and economy relate to each other in faith-based businesses. It also elaborates on a recurrent idea in theological literature that reflections on different visions of time can advance theological analyses of the relationship between Christianity and capitalism. More specifically, this article brings results from an ethnographic study of two faith-based businesses into conversation with the ethicist Luke Bretherton’s presentation of different understandings of the relationship between Christianity and capitalism. Using Theodore Schatzki’s theory of timespace, the article examines how time and space are constituted in two small faith-based businesses that are part of the two networks Business as Mission (evangelical) and Economy of Communion (catholic) and how the different timespaces affect the religious-economic configurations in the two cases and with what moral implications. The overall findings suggest that the timespace in the Catholic business was characterized by struggling caused by a tension between certain ideals on how religion and economy should relate to each other on the one hand and how the practice evolved on the other hand. Furthermore, the timespace in the evangelical business was characterized by confidence, caused by the business having a rather distinct and achievable goal when it came to how they wanted to be different and how religion should relate to economy. There are, however, nuances and important resemblances between the cases that cannot be explained by the businesses’ confessional and theological affiliations. Rather, there seems to be something about the phenomenon of tension-filled and confident faith-based businesses that causes a drive in the practices towards the common good. After mapping the results of the empirical study, I discuss some contributions that I argue this study brings to Bretherton’s presentation of the relationship between Christianity and capitalism.
