Summary Linguistic historiography analyzes how linguistic knowledge has been acquired, stored, used and diffused. This article examines what can happen if linguists rely on copies of source data rather than the source data itself. It takes as a case study linguistic data from Siraya, a now-extinct Formosan language. Documents compiled in the seventeenth century by Dutch missionaries in Taiwan form a significant source of data for Siraya. One such document, a wordlist known as the Utrecht Manuscript (UM), is the principal source for the lexicon of one variety of Siraya, “Siraya Proper”. It has been published three times. Each edition, however, contains many errors. These editions, rather than the manuscript, have been used by scholars investigating Siraya. This article aims to correct errors in the editions and secondary literature on the UM with my readings of the manuscript itself. It therefore presents a more accurate record of the lexicon of “Siraya Proper” as well as illustrating the importance of using primary rather than secondary sources of linguistic data. Finally, it introduces an online edition of the UM, which will provide scholars and language revivalists with a useful resource for this lexicon.

The first in-depth study of the society and culture of Roman and late antique Egypt that uses everyday artefacts as its principal source of evidence, this book transforms our understanding of many aspects of its society and culture. It represents a fundamental reference work for scholars, with much new and essential information on a wide range of artefacts, many of which are found not only in Egypt, but also in the wider Roman and late antique world. It also sets out a new interpretation of everyday life and aspects of social relations in Egypt in the period under study. By taking a social archaeology approach, it contributes substantial insights into everyday practices and their social meanings in the past. Artefacts from UCL’s Petrie Museum of Egyptian Archaeology are the principal source of evidence. Most of these objects have not been the subject of any previous research. The book integrates the close study of artefact features with other sources of evidence, including papyri and visual material. There are two principal parts to the book, Part I: ‘Exploring the Social Functions of Dress Objects’, and Part II: ‘The Domestic Realm and Everyday Experience’. An important theme is the life course, and how both dress-related artefacts and ordinary functional objects construct age and gender-related status, and facilitate appropriate social relations and activities. There is also a particular focus on wider social experience in the domestic context. Other topics covered include economic and social changes across the period studied.

Self-propelled flapping foils with distinct locomotion-enabling kinematic restraints exhibit a remarkably similar Strouhal number ( $St$ )-Reynolds number ( $Re$ ) dependence. This similarity has been hypothesized to pervade diverse forms of oscillatory self-propulsion and undulatory biolocomotion; however, its genesis and implications on the energetic cost of locomotion remain elusive. Here, using high-resolution simulations of translationally free and restrained foils that self-propel as they are pitched, we demonstrate that a generality in the $St$ - $Re$ relationship can emerge despite significant disparities in thrust generation mechanics and locomotory performance. Specifically, owing to a recoil reaction induced passive heave, the fluid's inertial response to the prescribed rotational pitch, the principal source of thrust in unidirectionally free and towed configurations, ceases to produce thrust in a bidirectionally free configuration. Rather, the thrust generated from the leading edge suction mechanics self-propels a bidirectionally free pitching foil. Owing to the foregoing distinction in the thrust generation mechanics, the $St$ - $Re$ relationships for the bidirectionally and unidirectionally free/towed foils are dissimilar and pitching amplitude dependent, but specifically for large reduced frequencies, converge to a previously reported unified power law. Importantly, to propel at a given mean forward speed, the bidirectionally free foil must counteract the out-of-phase passive heave through a more intense rotational pitch, resulting in an appreciably higher power consumption over the range $10 \leq Re \leq 10^3$ . We highlight the critical role of thrust in introducing an offset in the $St$ - $Re$ relation, and through its amplification, being ultimately responsible for the considerable disparity in the locomotory performance of differentially constrained foils.

The very first verse revealed to the Prophet of Islam ﷺ, namely ﴾ Read in the name of your Lord ﴿ implied the concept of knowledge that corresponds with the intellectual attestation of the first article of Islamic faith, that is, the belief in the unity of God, which for its part requires a specific kind of knowledge related to the Divine. With the same token, the Revelation continued to provide the Prophet ﷺ with the intellectual and spiritual insights that he ﷺ perfectly transformed into the nucleus based on which the first Islamic state known as the Madīnian polity was firmly established. Hence, in this paper, the analysis will cover the intellectual dimensions of the Madīnian polity portrayed here in three essential aspects: the revelation as the principal source of knowledge, the affirmation as the intellectual and practical application of knowledge, and the manifestation as the individual and communal reflection of knowledge. I will argue that the said aspects as they were displayed in the Madīnian polity are the core factors that underpin the Islamic governance as such.

Polycyclic aromatic hydrocarbons (PAHs), even at low concentrations, have been shown to trigger changes in life cycles and provoke abnormal behaviors in numerous marine organisms. From May 2019 to September 2020, particulate and dissolved PAH concentrations were analyzed on the surface water of West Nanao Bay, Japan, to determinate their levels, emission sources, environmental pathways, and ecological risks at this remote but semi-enclosed bay. The 14 targeted PAHs were analyzed by HPLC-fluorescence detector. Mean total PAH concentrations were lower than 20.0 ng L−1 for most samples. Based on fluoranthene (Flu) to pyrene (Pyr) ([Flu]/[Flu + Pyr]) and benzo[a]anthracene (BaA) to chrysene (Chr) ([BaA]/[BaA + Chr]) isomeric ratios and a varimax rotated PCA, it was established that biomass combustion was the principal source in the particulate phase and that liquid fossil fuel combustion was the principal source in the dissolved phase. From salinity and turbidity distribution, riverine discharges were determined to be the major and continuous transportation pathway of particulate PAHs. It was observed that rain events had a role in the transport of dissolved PAHs. The risk quotients (RQ∑14 PAHs (NCs): 0–84.53) indicated that PAHs represented a very low to low acute environmental risk. The results of this study will contribute to filling the paradigm gap of ecotoxicological studies in remote areas, working as a booster for future in-lab studies of non-lethal implications of endocrine disruptors such as PAHs.

There have been frequent calls in the literature for a more comprehensive understanding of marketing impact on long-term firm performance. Retail scanner data has been the principal source of empirical evidence in this strategic domain, but it cannot explain the behavioural shifts that underpin the sales dynamics it reports. With the availability of far larger and extended household panels, it is now possible to observe the effects of accumulating penetration on brand and category buying over many years. This type of data nevertheless presents theoretical and methodological challenges to researchers. In this article, we discuss an approach to extending established marketing theory to long-run repeat buying and then outline the inherent constraints of long-term panels. We illustrate these challenges using one-, five- and 10-year panel datasets and present a research agenda to progress explanatory theories of long-run brand building and category growth in this new but so far mostly untapped resource.

Vision loss causes dramatic changes in brain function which are thought to facilitate behavioral adaptation. One interesting prospect is that the cholinergic signals are involved in this blindness-induced plasticity. Critically, the nucleus basalis of Meynert is the principal source of the cholinergic signals, however, no studies have yet investigated whether the nucleus basalis of Meynert is altered in blindness. Therefore, here we examined its structure, cerebrovascular response, and the resting-state functional connectivity in blind individuals. We found that the global signal of the nucleus basalis of Meynert as well as its network connectivity with the visual, language, and default mode network is significantly enhanced in early blind individuals. On the other hand, its structure and cerebrovascular response remain unchanged in early blind individuals. Further, we observed that less visual experience predicts stronger global and network connectivity of the nucleus basalis of Meynert. These results suggest that the nucleus basalis of Meynert develops a stronger neuromodulatory influence on the cortex of blind individuals at both global and network levels.

The Prologue sets the scene by describing the book’s protagonist on his deathbed in the late spring of 1797 and the thoughts that may well have come into his mind concerning his life before and, especially, during the French Revolution. It describes the principal source on which the study is based, the extensive correspondence from Colson to his friend, almost miraculously preserved in the archives of a small town in Central France. It also introduces some of the major themes to be examined. It argues that the life of Colson is important, first, as it throws light on the beliefs and behavior of the whole community of his neighbors on a small street in central Paris, many of whom would come to describe themselves as “sans-culottes”; second, as it illuminates his relations with the noble family for whom he worked as lawyer and financial accountant; and third, as it provides the example of a relatively elderly citizen in the Revolution—who was sixty-two years old in 1789. It concludes with a rapid overview of the chapters in the book.

The transfer of technology has been mainly subject to the North-South dichotomy where the North is regarded as the principal source of technical knowledge to the South. Nevertheless, as new economic powers emerge in the South, the scene of international technology transfer is changing rapidly. Many South-South endeavors on transfer of technology are on the rise. Thus, a new model of transfer of technology is gaining momentum, in particular the South-South Model of transfer of technology. This paper aims to look at this issue by attempting to answer the following questions: How did South-South cooperation in the field of transfer of technology evolve? How did the rise of the South affect the North-South conflict in the context of transfer of technology? What is the impact of the South-South cooperation in the field of technology transfer on the North?

The Public Order Act 1986 is the principal source of public order offences. These are riot, violent disorder and affray, along with inducing fear of violence and behaviour likely to cause harassment, alarm or distress. Some of the offences in the 1986 Act may be committed in private, but their public order foundations are paramount and these offences should not be treated as merely additional offences against the person. This chapter deals with offences against public order. It also considers harassment, alarm or distress, racially aggravated public order offences and acts intended or likely to incite racial or religious hatred and hatred on the grounds of sexual orientation. The chapter concludes by looking at public nuisance and vicarious liability.
