Early Pattern Formation

The processes of development form a continuum that begins with gametogenesis and ends only with the death of the individual organism. It is therefore artificial to try to define separate phases and stages of these processes, just as it is artificial to try to separate the structural history of the embryo into a series of discrete forms through time with discrete and definable properties (let alone trying to match such artifacts to putative phylogenetic stages). But at the same time, the sequence of mechanisms of development is hierarchically organized. The major early event is the transfer of control over development itself from the purely maternal factors inherited within the egg and particularly in the egg cytoplasm, to the switching on of the zygotic genome and transfer to zygotic control of cell function, interaction and differentiation, morphogenesis and cytodifferentiation. This transfer does not occur at a single instant, nor is it easy to generalize about it even with a single group of organisms. Other landmarks are harder to find, especially ones that can be compared consistently over a range of different organisms. However, one can roughly divide the processes of development, for the purpose of organizing a discussion at least, into two main phases: early and late pattern formation phases. Early pattern formation can be defined as that part of the developmental sequence in which all the major mechanisms that control the shaping of the embryo, both its morphogenesis and cytodifferentiation, are set into place. In a vertebrate, early pattern formation would be everything from gametogenesis up to and including gastrulation, by which time all the essential elements of tissue interaction that will cause the morphogenesis of the embryo have not only been regionally defined and correctly positioned, but have started to function. Late pattern formation comprises the stages of morphogenesis and cytodifferentiation. As we will see, morphogenesis itself can be divided into two stages, early and late: roughly speaking, in the earlier part, morphogenetic pattern-controlling mechanisms are set in place, and in later stages their results are expressed.

Abstract Much attention has been given to the pioneering achievements of the Christian Hebraists of the sixteenth century in transcribing the essential elements of traditional Torah chant into Western musical notation. One of these transcriptions, however, is unique. Johannes Reuchlin’s De Accentibus et Orthographia Linguae Hebraicae of 1518 contains not only the ‘accents of biblical recitation’ themselves, but also a complete four-part harmonization of these tropes by one of Reuchlin’s students, Christoph Schilling, in the German choral style of the period. Although Schilling’s arrangement of the individual accents has been mentioned in passing by numerous scholars, it has never been published in a modern edition, nor applied to the actual practice of chanting biblical texts. In this article, I discuss some of the general background to cantillation, accentuation, and the role of the German Humanists in preserving this oral tradition in written form. Comparisons between sixteenth-century and twentieth-century biblical chant are made in relation to the melodic and harmonic characteristics of Schilling’s notation, and this leads to an assessment of some of the problems concerning the realization of these raw materials for ‘live’ performance. Three short extracts from the Pentateuch are then presented as working examples based upon Schilling’s arrangement. In conclusion, the possible motives and intentions behind this intercultural phenomenon will be considered, as will its significance in the long history of Judeo-Christian syncretism in music.

A methodological discussion of the value and use of parallels from the history of religion retains its value, especially to-day, when the ‘religionsgeschichtliche Methode’ is rejected even by some scholars of genuine insight.Deissner,a conservative theologian, recognizes in principle the justification of the method, and aims to set the New Testament in its relation to the history of civilization and of religion. He holds the comparison of Christian traditions with kindred non-christian facts to be indispensable, but criticizes the usual method, as employed for instance by Bousset, on the ground that it pays too much attention to the connection of the New Testament with the world of religion outside and too little to the specific nature of Christianity itself. To him, comparison with other religions is a means for determining the connection and contact of the New Testament with the world at large (for example, in the field of language) with the object of showing how incomparable is the New Testament, how underived, real, original — dogmatically speaking, of showing its supernatural character, built up of elements which the conception of a purely immanent cause leaves unexplained. His book is intended to be conciliatory, and formulates in detail various sound principles, such as the distinction between adopting alien religious terminology and filling it with new and distinctive contents. He errs in making the problem too simple and trying to solve it by a dogma. The relations of primitive Christianity to the development of religion in general are too complicated to be covered by the mere distinction between form and contents. It is also a mistake to identify the individual and distinctive with the essential. To the essential elements of primitive Christian tradition belong in fact those which find complete analogy in syncretism and Judaism, and it is dangerous to rest the character of Christianity as revelation on those elements only which a scholar thinks not to be derivative or to have no analogies. Others may think differently, or the missing analogies may be found to-morrow! (See also Bultmann, ThLZ, 1922, no. 10.)

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

The nineteenth century introduced developments in science and medicine that made the eradication of pain conceivable for the first time. This new understanding of pain brought with it a complex set of moral and philosophical dilemmas. If pain serves no obvious purpose, how do we reconcile its existence with a well-ordered universe? Examining how writers of the day engaged with such questions, this book offers a compelling new literary and philosophical history of modern pain. The book provides close readings of novelists Charlotte Brontë and Thomas Hardy and political and natural philosophers John Stuart Mill, Harriet Martineau, and Charles Darwin, as well as a variety of medical, scientific, and popular writers of the Victorian age. The book explores how discussions of pain served as investigations into the status of persons and the nature and parameters of social life. No longer conceivable as divine trial or punishment, pain in the nineteenth century came to seem instead like a historical accident suggesting little or nothing about the individual who suffers. A landmark study of Victorian literature and the history of pain, the book shows how these writers came to see pain as a social as well as a personal problem. Rather than simply self-evident to the sufferer and unknowable to anyone else, pain was also understood to be produced between persons—and even, perhaps, by the fictions they read.

This article offers an analysis of the identity work of a black transgender woman through life history research. Identity work pertains to the ongoing effort of authoring oneself and positions the individual as the agent; not a passive recipient of identity scripts. The findings draw from three life history interviews. Using thematic analysis, the following themes emerge: institutionalisation of gender norms; gender and sexuality unintelligibility; transitioning and passing; and lastly, gender expression and public spaces. The discussion follows from a poststructuralist conception of identity, which frames identity as fluid and as being continually established. The study contends that identity work is a complex and fragmented process, which is shaped by other social identities. To that end, the study also acknowledges the role of collective agency in shaping gender identity.

The study of Aramaic Bible translations (Targumim) continues to be a valuable source of information, not only for uncovering the history of biblical interpretation but also for providing insights for the study of linguistics and translation techniques. In comparison with work done on the Pentateuchal Targumim and Targum Former Prophets, research on the individual books of Targum Minor Prophets has been scant. By providing an overview of selected source material this review seeks (i) to provide incentives for more focussed studies in the field of Targum Minor Prophets and (ii) to motivate new integrated research approaches which are now made possible with the assistance of highly developed software programmes.

Geographic distribution and habitat preferences of Saxicola rubicola rubicola (Linnaeus, 1766), S. maurus variegatus (S.G. Gmelin, 1774), and S. m. armenicus (Stegman, 1935) inhabiting the Caucasian Isthmus and adjacent areas are described in detail. We examined the individual, sexual, age, seasonal and geographical variations of seven main diagnostic features of both plumage and morphometrics (exactly, the length of wing and tail) using 381 skin specimens. Substantially improved diagnoses of S. m. variegatus and S. m. armenicus are provided. After a thorough examination of the materials and history of the expedition of Samuel Gmelin in 1768–1774, and his description of Parus variegatus, it was concluded that the type locality of this taxon was the vicinity of Shamakhi in Azerbaijan not Enzeli in North-Western Turkey. It is also shown the fallacy of the recently proposed attribution of the holotype of the northern subspecies S. m. variegatus to the southern taxon S. m. armenicus and synonymisation of these names, as well as the replacement of the name S. m. variegatus by its junior synonym S. m. hemrichii Ehrenberg, 1833 for the northern subspecies.

Songkhla Lake Basin has a long history of at least 6,000 years and has a wide variety of tourism resources including nature, history, beliefs, culture and various traditions of the local people. It covers 3 provinces, the whole area of Phatthalung, 12 districts of Songkhla and 2 districts of Nakhon Si Thammarat Province. It has an area of approximately 8,727 square kilometers. There are many tourist attractions because the basin has a long history through different eras, natural, historic, ancient sites, and the culture of the local people. In 2018, both Thai and foreign tourists visited Songkhla and Phatthalung, which is the main area of Songkhla Lake Basin. The total number of tourists that came was 7,628,813 and 1,641,841 and an income of 68,252.64 and 3,470.96 million baht was generated from each province, respectively (Ministry of Tourism and Sports, 2020). Although Songkhla Lake Basin has various tourist attractions, the promotion of tourism with the involvement of government agencies in the past mainly focused on promoting tourism along with the tourist attractions rather than encouraging tourists to experience and learn the culture of the people living in the area; the culture that reflects the uniqueness of the people in the south. This study, therefore, aims to find creative tourism activities in SLB in order to increase the value of tourism resources, create tourism activities that are aligned with the resources available in the community and increase the number of tourists in the area. Data for this study were collected using a secondary source of data collection method. It was done through a literature review of related documents, texts, magazines, and research which focus on Songkhla Lake Basin as a guideline for designing tourism activities. The field survey was done through twelve community-based tourism sites in SLB to find creative tourism activities. Data on each activity were collected in detail by interviewing the tourism community leaders and the local people. Content analysis was used to describe the individual open-ended questions by focusing on the important issues and the information obtained was presented as a narrative. Keywords: Songkhla Lake Basin, Creative Tourism, Local Wisdom

Accounting educators no doubt agree that diversity is an important and much neglected part of accounting education. They further recognize that it is difficult to incorporate this important topic into the accounting curriculum. This paper describes the efforts of various professors to expose business and accounting students to the evolution of diversity issues related to the accounting profession by using the book A White-Collar Profession [Hammond, 2002]. A White-Collar Profession: African-American CPAs Since 1921 is a seminal work which presents a history of the profession as it relates to African-American CPAs and documents the individual struggles of many of the first one hundred blacks to become certified. This paper describes efforts of faculty at four different colleges to utilize this book in their teaching of accounting. Instructors found that students not only developed an enhanced awareness about the history of the accounting profession, but that other educational objectives were advanced, such as improved communication and critical thinking skills, increased social awareness, and empathy for others. African-American students, in particular, embraced the people in the book as role models, while most every student saw the characters as heroic in a day when the accounting profession is badly in need of role models and heroes. This is encouraging given the profession's concern with diversity and the attention and resources directed at increasing the number of minorities entering the profession.

This chapter examines the classical Hindu life-cycle rites, the term saṃskāra and its history, and the main sources (Gṛhyasūtras and Dharma texts). It presents a history of the traditional saṃskāras and variants in local contexts, especially in Nepal. It describes prenatal, birth and childhood, initiation, marriage, old-age, death, and ancestor rituals. Finally, it analyzes the transformational process of these life-cycle rituals in the light of general theories on rites of passage. It proposes, in saṃskāras, man equates himself with the unchangeable and thus seems to counteract the uncertainty of the future, of life and death, since persons are confronted with their finite existence. For evidently every change, whether social or biological, represents a danger for the cohesion of the vulnerable community of the individual and society. These rituals then become an attempt of relegating the effects of nature or of mortality: birth, teething, sexual maturity, reproduction, and dying.
