Chapter 6, “A Deeper Layer of Reality,” describes my path to quarks, relating events starting as a graduate student in the spring of 1963 through the summer of 1964 when my work on quarks was essentially completed. A way of judging improbable theories is presented that, when applied to the quark model, pits the a priori likelihood that quarks exist against the difficulty of explaining the experimental data in a theory without quarks.
After a preliminary discussion of symmetry as applied to particle classification, and the constraints it places on the wave functions of particles, a detailed discussion of constituent quarks with spin is presented, based on my 1964 Erice Summer School Lectures. This takes place at two levels, first to capture the main ideas, then, with more detail, to enable the reader to decide if they would have believed that a fundamental theory based on quarks would eventually explain the strong interactions. Selection rules governing the change of strangeness in weak decays, and their relation to the change in charge of the strongly interacting particles, are derived. A graphical calculus based on quarks for calculating hadron couplings is introduced.
This chapter clarifies the difference between changes in levels of cost versus growth of cost and focuses on the latter. This is because increases in spending may be good if we are getting something for that growth; it all depends whether it is going toward “waste” or if we are obtaining value for that spending in the form of health outcomes – a return on investment. Four targets of cost containment are outlined: administrative costs, competition, state-based spending targets, and value-based payment. It is acknowledged that administrative costs are high in the US in part because consumers have choice over plans, benefits, providers, and networks (as opposed to once centralized system); with this choice comes coordination, information, and standardization costs. Excessive market power due to consolidation may also lead to the extraction of high prices from consumers beyond what would be possible with improved market-level competition. The chapter concludes by addressing the recent flattening in medical spending growth and what might happen in the future.
As soon as one comes to terms with Origen’s historiographically and literarily sensitive criteria for how to read and understand the Gospel narratives, one may realize that the Gospels have simultaneously formed his vision of what history itself is by presenting this life to us “under the form of history” and “in figures” they reveal that history is itself a “sign of something.” Thus, for Origen, when one finally reaches into the “depths of the evangelical mind” and discerns “the naked truth of the figures therein,” one discovers a “spiritual Gospel,” yes, but one breaks through the “shell” of these historical narratives only to find history anew, even one’s very own, transfigured and “taken up into the Gospel” – the eternal Gospel – whose sacrament is the glorified Son of Man.
Chapter 5 focuses on Murray Gell-Mann who dominated particle physics for more than a decade starting in the mid-1950s. His perspective, style, and major contributions to physics, while I knew him, are described. A comparison of Feynman and Gell-Mann’s views on how to practice physics, and what they valued concludes this chapter.
A succession of toy field theories of increasing generality are described, the final one, missing all strong interactions, is based on mathematical quarks from which equal-time commutation relations of the weak and electromagnetic currents are abstracted. The Eightfold way and the Gell-Mann—Okubo mass formula are discussed, and Gell-Mann’s view of quarks is described in some detail. Examples of a darker side -- his pattern of inadequate attribution, that I only fully realized while writing this book -- are also given.
Chapter 6 transitions to the case of the Philippines to provide a comparative analysis of regime complex effectiveness. The chapter begins with a political economy analysis of the domestic actors and interests involved in the energy sector in the Philippines, then delves into the history of geothermal development with an analysis of the impacts of the clean energy regime complex actors on barriers to geothermal development over time. The major findings of this chapter indicate that early domestic political support for geothermal development under the Marcos and Ramos regimes was a response to the exogenous shocks of energy crises. This response to exogenous shocks opened pathways of change that were key in catalyzing geothermal development in the country that later placed the Philippines as the world’s second largest producer for several decades. In the Philippines, an embrace of the energy transition enabled the positive impact of the clean energy regime complex on geothermal development. In Indonesia, domestic political resistance to the energy transition limited regime complex effectiveness.
The book concludes in Chapter 8 with a summary of the major theoretical and empirical findings on the clean energy regime complex’s emergence and effectiveness across Indonesia and the Philippines, and a discussion of the theory’s broader generalizability, further research opportunities, and policy implications and recommendations for fostering energy transitions in a world of complex governance.
Post-Northian institutional economics has been predicated on the socially extended and enactivist concept of cognitive institution. It has recently been suggested that this framework should include North’s definition of institutions as ‘rules of the game’. In this paper, we agree with this normative turn but take issue with the mental-model framework in which it is proposed. Retaining both shared mental models and rules of the game remains too ‘Northian’, even if complemented with enactivist dynamic principles of mental-model change. We propose an alternative enactivist concept of norm that entirely avoids mental models. We base it on an alternative social ontology that considers norms as located in the relation between agents and institutions. The implications of this relational ontology for the norms (or principles) of rationality are also discussed. We argue that a truly relational framework requires abandoning the adaptationist norm of rationality in favour of coordinative rationality principles.
Understanding biotic responses to environmental changes will help identify extinction risks and direct conservation efforts to mitigate negative effects associated with anthropogenic-induced environmental changes. Here we use the Quaternary fossil record of mole salamanders (Ambystoma) from the southwestern United States and northern Mexico to reveal geographic patterns of extirpation since the Pleistocene. Ambystoma are known to have previously inhabited regions of central Texas on the Edwards Plateau; however, they are largely absent from the region today. We used a well-dated fossil record of Ambystoma from Hall’s Cave combined with other fossil sites in the region to deduce why Ambystoma was ultimately extirpated from the Edwards Plateau and to test hypotheses related to temperature-driven body-size changes in line with the temperature–size rule. We propose that Ambystoma was likely extirpated from the region due to changing temperature and precipitation regimes that caused increased mortality and disruptions to breeding and larval development. We found some support for decreased body size in Ambystoma with increased temperature during the late Pleistocene, suggesting that body size may be an important feature to monitor in modern populations of Ambystoma as salamanders become subjected to increasingly hotter temperatures in the coming decades.
This chapter brings together the threads of Chapters 8 and 9 to advance an alternative theoretical foundation for international organizations. First, it explains why we should understand the state as an artificial rather than as a natural construct, even for the purposes of international law. It traces states’ emergence back to a national community’s capacity for self-description through socially grounded rules of transformative re-description. Doing so, this chapter unveils the inherent openness of international law to admitting any other institutions that can also be traced back to this capacity. Thus, it recasts the state as just one institution among a family of such entities. All these entities, including international organizations, are equally admissible by default in international law without the need for any legislative intervention to that effect.
A closer look at changes in women’s education, age of marriage, employment, and the reasons for the enduring value of women’s skilled domestic work. Women’s postrevolutionary legal position as second-class citizens exists in tandem with gains in women’s social status indicators: improvements in women’s literacy, later and more egalitarian age of marriage, lower fertility rates, and improved indicators of basic household consumption. Women’s stubbornly low contemporary participation rate in formal employment is complicated by the prerevolutionary prevalence of child labor, and postrevolutionary improvements in girls’ school attendance. Low rates of formal employment also mask women’s crucial contributions to household economies through social labor. Local food culture and the premium attached to women’s skilled home cooking provide the basis for social and economic networks that bypass state control. The common value of local food culture provides a foundation for social identity and a recognizable form of capital that offsets the frustrations associated with limited the opportunities of the formal market.
Gay and Meier asked if a trisection diagram for the Gluck twist on a spun or twist-spun 2-knot in $S^4$ obtained by a certain method is standard. In this paper, we show that the trisection diagram for the Gluck twist on the spun $(p+1,p)$-torus knot is standard, where p is any integer greater than or equal to 2.
Garra gotyla is a benthopelagic freshwater cyprinid fish native to Asia, valued for both food and ornamental purposes; nevertheless, its parasitic diseases are poorly understood. The present study investigated the presence and ecological indices (prevalence and intensity) of monogenean parasites infecting G. gotyla in Mizoram, northeast India. Additionally, the study aimed to assess the phylogenetic relationships among three closely related dactylogyrid genera: Dactylogyrus, Dogielius, and Dactylogyroides. Monogeneans were initially identified based on the comparative morphology of their sclerotised haptoral and reproductive structures, followed by BLASTn comparisons of their partial 28S rRNA gene sequences. Two dactylogyrid species, Dactylogyrus labro sp. n. and Dogielius salpinx sp. n., were recovered and are described herein as new to science. Dactylogyrus labro was found to infect all examined fish, whereas D. salpinx had a slightly lower prevalence, ranging from 76.5% to 83.3% across different sampling sites. The phylogenetic insights from these species presented in this study highlight the complex evolutionary relationships within these three genera. Further, this study provides the first confirmed molecular data for a Dogielius species, allowing for much-needed phylogenetic studies on the genus and filling a gap in sequencing data for Indian monogeneans. Since all monogeneans are potentially hazardous parasites, more studies are needed to map their diversity and effects on host fishes in this region.
This article introduces the artistic and community practice of Treehouse Shakespeare Ensemble (2022–2023) as emblematic of an ensemble-based MFA training model. Drawing on scholarship on community theatre, the article argues that a grassroots training model has the potential to bridge the theoretical division between university theatre and community partner.
This chapter analyses the failure of numerous ‘popish mortgage bills’ in late eighteenth-century Ireland. It contextualizes these legislative efforts not only within the histories of the penal laws and Catholic emancipation, but also within the histories of mortgage law in Ireland, England, and other parts of the British Empire. The bills demonstrated Irish lawmakers’ interest in guaranteeing sources of credit for landowners, and indicated at least some confidence in the protections that would be afforded Protestant debtors by the core doctrine of the equity of redemption. The widespread testing of that doctrine, however, raised new questions about creditor power that informed fears about Catholic power, and these became central to legal and political debate. The failure of these bills reflected common concerns about predation and fraud in credit relations, and particular unease about the ways in which mortgage law might contribute to constitutional change, undermining Ireland’s Protestant ascendancy.
In A Midsummer Night’s Dream, competing approaches to timekeeping raise questions not only about the nature of time, but about who has influence over whom, why and when. This article explores overlooked intersections between time-practices and politics of place, empire, class and technology which preoccupy Shakespeare in Dream.
In 1796, as Britain fought endless wars within Europe and overseas, one of the three leading theorists of the picturesque, Uvedale Price, contemplated the ideal relationship between landscapes and visual arts:
Every place, and every scene that are worth observing, must have something of the sublime, the beautiful, or the picturesque; and every man will allow that he would wish to preserve and to heighten, certainly not to destroy, their prevailing character. The most obvious method of succeeding in the one, and of avoiding the other, is by studying their causes and effects … and sure I am, that he who studies the various effects and characters of form, colour, and light and shadow, and examines and compares those characters and effects, the manner in which they are combined and disposed, both in pictures and in nature,—will be better qualified to arrange, certainly to enjoy, his own and every scenery, than he who has only thought of the most fashionable arrangement of objects; or has looked at nature alone, without having acquired any just principles of selection.
Living through the French Revolution and its aftermath, Price here suggests that the only semblance of stability could be found in the vindication of the established order. This is evident in his advocacy of the preservation and heightening of the features of a given landscape. The result is a blend of politics and aesthetic choices that necessitates framing one correctly in order to truly appreciate the other.
