“But who will guard the guardians?” I revisit this age-old question under the following assumptions: (i) guardians are devoid of ethical motives and have quasilinear preferences, (ii) guardians monitor one another through a monitoring chain, and (iii) any two consecutive guardians in the chain can bargain away “inefficient” punishments through corruptive arrangements. Under these assumptions, monitoring is impossible unless rewards or punishments are unbounded. When material incentives are bounded and local corruption is feasible, the answer to the initial question is “no one.”

Abstract Objective In this study we compare the amino acid and codon sequence of SARS-CoV-2, SARS-CoV and MERS-CoV using different statistics programs to understand their characteristics. Specifically, we are interested in how differences in the amino acid and codon sequence can lead to different incubation periods and outbreak periods. Our initial question was to compare SARS-CoV-2 to different viruses in the coronavirus family using BLAST program of NCBI and machine learning algorithms. Results The result of experiments using BLAST, Apriori and Decision Tree has shown that SARS-CoV-2 had high similarity with SARS-CoV while having comparably low similarity with MERS-CoV. We decided to compare the codons of SARS-CoV-2 and MERS-CoV to see the difference. Though the viruses are very alike according to BLAST and Apriori experiments, SVM proved that they can be effectively classified using non-linear kernels. Decision Tree experiment proved several remarkable properties of SARS-CoV-2 amino acid sequence that cannot be found in MERS-CoV amino acid sequence. The consequential purpose of this paper is to minimize the damage on humanity from SARS-CoV-2. Hence, further studies can be focused on the comparison of SARS-CoV-2 virus with other viruses that also can be transmitted during latent periods.

Abstract Background Juvenile idiopathic arthritis (JIA) requires some form of lifelong management, with at least one third of children symptomatic in adulthood. Therefore, empowering children to competently self-manage their health and wellbeing across the lifecourse is logical, while supporting families in their shared-management role during childhood. However, there was a limited theoretical basis to the self- and shared-management of JIA across the lifecourse. The objective is to explore the factors facilitating the self- and shared-management of JIA using a realist approach to evaluation. Methods Guided by the Individual and Family Self-management Theory, a three-stage realist approach to evaluation was undertaken: 1) initial JIA self- and shared-management question theories were elicited from literature reviews and stakeholder insights [1]; 2) seven initial question theories were tested using teacher-learner cycle interviews with 20 participants; 3) findings were analysed using a theory-driven approach to thematic analysis, using deductive, inductive, and retroductive reasoning to extend or refute the initial question theories, in order to identify demi-regularities in the data. Results Six refined JIA self- and shared-management question theories emerged: 1) meaningful and bespoke self-management support across the life course for children and young people with JIA; 2) recognised and valued shared-management support for the families of children and young people with JIA, with autonomy in mind; 3) individual healthcare plans as a shared management communication tool to facilitate optimal management of JIA; 4) consistent recognition, value, and encourage of self- and shared-management support from the paediatric rheumatology multi-disciplinary team and associated professionals; 5) child, young-person, and family-focused paediatric rheumatology care and support services across the lifecourse; and 6) bespoke and inclusive approaches by education providers to enable children and young people with JIA to feel safe, supported, and able to fulfil their potential. Conclusion There is an increasing recognition of the importance of self- and shared-management of JIA and other paediatric-onset chronic conditions. However, there is a lack of an overall, cohesive approach to self- and shared-management between healthcare providers, education providers, and patient/parent organisations. The findings from this study illuminate the factors facilitating JIA self- and shared-management at individual, interpersonal, institutional and infrastructural levels, bearing relevance to individuals and organisations involved in caring for, and supporting children with JIA and their families.

we’ve installed the foundation piles and are ready to start building Mirror worlds. In this chapter we discuss (so to speak) the basement, in the next chapter we get to the attic, and the chapter after that fills in the middle region and glues the whole thing together. The basement we are about to describe is filled with lots of a certain kind of ensemble program. This kind of program, called a Trellis, makes the connection between external data and internal mirror-reality. The Trellis is, accordingly, a key player in the Mirror world cast. It’s also a good example of ensemble programming in general, and, I’ll argue, a highly significant gadget in itself. The hulking problem with which the Trellis does battle on the Mirror world’s behalf is a problem that the real world, too, will be confronting directly and in person very soon. Floods of data are pounding down all around us in torrents. How will we cope? what will we do with all this stuff? when the encroaching electronification of the world pushes the downpour rate higher by a thousand or a million times or more, what will we do then? Concretely: I’m talking about realtime data processing. The subject in this chapter is fresh data straight from the sensor. we’d like to analyze this fresh data in “realtime”—to achieve some understanding of data values as they emerge. Raw data pours into a Mirror world and gets refined by a data distillery in the basement. The processed, refined, one-hundredpercent pure stuff gets stored upstairs in the attic, where it ferments slowly into history. (In the next chapter we move upstairs.) Trellis programs are the topic here: how they are put together, how they work. But there’s an initial question that’s too important to ignore. we need to take a brief trip outside into the deluge, to establish what this stuff is and where it’s coming from. Data-gathering instruments are generally electronic. They are sensors in the field, dedicated to the non-stop, automatic gathering of measurements; or they are full-blown infomachines, waiting for people to sit down, log on and enter data by hand.

The question considered in this chapter is whether decentralization is likely to hurt or help national unity in “countries at risk.” We begin with a literature review, focusing on three particular questions: the size and number of nations; the determinants of decentralization; and, finally, and bearing most directly on our topic, the links between decentralization and political outcomes. We next set out in capsule form some of the very mixed stories of linkages between decentralization and national unity found in Europe and the Middle East and North Africa (MENA) region, before considering more closely the ongoing discussions of secession in three European countries – Belgium, Spain and the United Kingdom. We conclude that the impact of decentralization on national unity is so complex and context-sensitive that no general answers to our initial question emerge: in some instances, decentralization may be an inducement for regions to stay in a country; in others, however, it may prove to be only a way station on the road to the exit.

In this engaging book, David Galenson formulates a complex question about modern art that he tries to answer with statistics, analysis, and exposition, enlivened with a rich sprinkling of well-chosen quotes. Posing an initial question “At what stage of their lives have modern painters normally done their best work?,” he finds that this age varies widely from artist to artist. This leads to the central problem: “is it by chance that some have made their greatest contributions early in their careers, and others late in theirs, or is there some general explanation that accounts for the variation?” (p. 4).

An excellent introduction to the metric theory of diophantine approximation is provided by [19], where, in chapter 1·7, the reader may find a discussion of the first two problems considered in this paper. Our initial question concerns the number of solutions of the inequalityfor almost all α(in the sense of Lebesgue measure on ℝ). Here ∥ ∥ denotes distance to a nearest integer, {βr}, {ar} are given sequences of reals and distinct integers respectively, and f is a function taking values in [0, ½] and with Σf(r) divergent (for convenience we write ℱ for the set of all such functions). It is reasonable to expect that, for almost all α and with some additional constraint on f, the number of solutions of (1) is asymptotically equal toas k tends to infinity.

This chapter offers a framework for legal research that concerns or applies ‘international law’ concepts, perspectives, and methodologies to intellectual property (IP). The idea is to discuss how research questions related to IP can be framed from the standpoint of international law. This begs an initial question: what do we mean by ‘international law’ and how does this relate to IP? Section I tackles these questions by offering a range of possible views on the notion of international IP Law. Section II then considers how a multidimensional conception of international law can serve to frame research questions on IP. It also gives some more concrete examples of the diversity in adopting an international law approach to IP.

AbstractsEstablishing and maintaining a quality management program (QMP) is easy in theory but difficult in practice. It requires considerable time, energy, and the full commitment of everyone involved, starting with the program management. The time involved in establishing a QMP varies in terms of time, depending on the scope of your system and the starting point. The initial question you need to ask is, “What standards, knowledge, do we already have?” In almost every case, the answer is “a considerable amount!” These days many hospitals already have accreditations or certifications like Joint Commission International (JCI), International Organization for Standardization (ISO), standards issued by the government and institutions and professional organizations. The most important pool of knowledge, however, is the education and experience of staff. All standards are initially created by colleagues in the field and, at least for FACT-JACIE, also further developed in a 3-year review cycle.

Abstract It is more than 20 years since Marysia Zalewski and feminist scholars posed ‘the man question’ in International Relations, repositioning the gaze from female subjectivities to a problematization of the subjecthood of man. The field of masculinity studies has developed this initial question to a deep interrogation of the relationship between maleness and violence. Yet public and policy discourse often reduce the complexity of masculinities within extremism to issues of crisis and toxicity. Governments have prioritized the prevention of extremism, particularly violent Islamism, and in so doing have produced as ‘risk’ particular racialized and marginalized men. This article asks, what are the effects of the toxic masculinity discourse in understanding the British radical right? It argues that current understandings of extremism neglect the central aim of Zalewski's ‘man’ question to destabilize the field and deconstruct patriarchy. They instead position Islamophobia—which is institutionalized in state discourse—as the responsibility of particular ‘extreme’ and ‘toxic’ groups. In particular, the article outlines two ways in which ‘toxic masculinity’ is an inadequate concept to describe activism in the anti-Islam(ist) movement the English Defence League (EDL). First, the term ‘toxic masculinity’ occludes the continuities of EDL masculinities with wider patriarchal norms; second, it neglects the role of women as significant actors in the movement. Using an ethnographic and empathetic approach to this case-study, the article explores how Zalewski's theoretical position offers a route to analysis of the ways in which masculinities and patriarchy entwine in producing power and violence; and to a discussion of masculinities that need not equate manhood with threat.
