The West End's East
The West End’s East End Practices, relations and aspirations among youth in Hovseter and Røa Helle Dyrendahl Staven Master’s thesis, Sociology Department of Sociology and Human Geography Faculty of Social Sciences UNIVERSITY OF OSLO Spring 2020 © Helle Dyrendahl Staven 2020 The West End’s East End. Practices, relations and aspirations among youth in Hovseter and Røa. http://www.duo.uio.no/ Trykk: Reprosentralen, University of Oslo II Abstract This aim of this thesis is to explore how youth life unfolds in Hovseter and Røa, two neighbouring areas characterised by social and spatial contrasts. Located in Oslo’s affluent West End, Hovseter stands out in this social and spatial landscape of detached and semi-detached houses and upper-middle-class ethnic majority residents due to its higher share of working-class and ethnic minority residents, tall apartment blocks, and social housing apartments. Policies on social mix in the Norwegian welfare state constitute the context for the thesis, in which policymakers aim to counter segregation and encourage social and cultural integration by promoting a diversity of social groups within neighbourhoods. Through the urban area programme Hovseterløftet, a youth club was initiated in order to promote social mixing and social bonds between working-class minority ethnic youths from Hovseter and upper-middle- class majority ethnic youths from Røa. This aim was in line with policies on social mix, in which policymakers assume that youth with less social and economic resources will benefit from creating social relationships with more resourceful peers. It was this particular context that motivated me to ask how social and spatial differences materialised in the daily lives of youths from Hovseter and Røa, how these differences influenced social interactions and relations, and lastly, how they affected the youths’ perceptions of school and their educational aspirations. -

(The DSB was published in 14 vol- umes in 1970–76, edited by C. C. Gillispie, New York: Charles Scribner's Sons.) I was later asked to write two more entries: for Parseval and Emil Leon Post. The entry for Post had to be done very quickly, and I could not have finished it without the generous help of one of his relatives. By the time the last of these articles was published in 1976, that for Giovanni Vailati, I had come out publicly as a homosexual and was involved in the gay liberation movement. But my article on Vailati was still discreet. If I had written it later, I would probably have included evidence of his homosexuality. The seven articles for the Dictionary of Scientific Biography have a uniform appear- ance. (The exception is the article on Burali-Forti, which I present here as I originally wrote it—with reference footnotes. -
Grade 6 Math Circles Working with an Abacus What Is an Abacus?
Faculty of Mathematics Waterloo, Ontario N2L 3G1 Grade 6 Math Circles Working with an Abacus February 12/13, 2013 What is an Abacus? An abacus is a mathematical tool used for computing large numbers quickly. The first abacuses were used over 4000 years ago by the Mesopotamians and are still used today by many merchants worldwide. Ancient Egyptians, Romans, Greeks, Chinese, Japanese, Russians and Native Americans also used abacuses, however each culture had a different name and its own unique version of the abacus. The Chinese Suanpan, is an abacus which makes addition, subtraction, multiplication, and division by hand very quick. The Suanpan is the type of abacus we will focus on. Making an Abacus An abacus is a box frame which usually has four to fourteen rods with seven beads on each rod. There is a separator beam which divides the rods into the upper deck and the lower deck. Ensure there are two beads in the upper deck and five beads in the lower deck. Rod Separator Upper Beam Deck Lower Deck Bead 1 Instructions for making your own abacus can be found at http://www.ee.ryerson.ca/~elf/abacus/popsicle/ Abacus Basics 1. Place the abacus so it lies flat on a desk. Make sure the lower deck is close to you and the upper deck is further from you. 2. Gently tilt the abacus up so that the upper beads rest on the separator beam and the lower beads rest at the base of the abacus, then lie the abacus flat again. This process is known as resetting the abacus. -
Proclus on the Elements and the Celestial Bodies
PROCLUS ON THE ELEMENTS AND THE CELESTIAL BODIES PHYSICAL TH UGHT IN LATE NEOPLAT NISM Lucas Siorvanes A Thesis submitted for the Degree of Doctor of Philosophy to the Dept. of History and Philosophy of Science, Science Faculty, University College London. Deuember 1986 - 2 - ABSTRACT Until recently, the period of Late Antiquity had been largely regarded as a sterile age of irrationality and of decline in science. This pioneering work, supported by first-hand study of primary sources, argues that this opinion is profoundly mistaken. It focuses in particular on Proclus, the head of the Platonic School at Athens in the 5th c. AD, and the chief spokesman for the ideas of the dominant school of thought of that time, Neoplatonism. Part I, divided into two Sections, is an introductory guide to Proclus' philosophical and cosmological system, its general principles and its graded ordering of the states of existence. Part II concentrates on his physical theories on the Elements and the celestial bodies, in Sections A and B respectively, with chapters (or sub-sections) on topics including the structure, properties and motion of the Elements; light; space and matter; the composition and motion of the celestial bodies; and the order of planets. The picture that emerges from the study is that much of the Aristotelian physics, so prevalent in Classical Antiquity, was rejected. The concepts which were developed instead included the geometrization of matter, the four-Element composition of the universe, that of self-generated, free motion in space for the heavenly bodies, and that of immanent force or power. -

An EM Construal of the Abacus
An EM Construal of the Abacus 1019358 Abstract The abacus is a simple yet powerful tool for calculations, only simple rules are used and yet the same outcome can be derived through various processes depending on the human operator. This paper explores how a construal of the abacus can be used as an educational tool but also how ‘human computing’ is illustrated. The user can gain understanding regarding how to operate the abacus for addition through a constructivist approach but can also use the more informative material elaborated in the EMPE context. 1 Introduction encapsulates all of these components together. The abacus can, not only be used for addition and 1.1 The Abacus subtraction, but also for multiplication, division, and even for calculating the square and cube roots of The abacus is a tool engineered to assist with numbers [3]. calculations, to improve the accuracy and the speed The Japanese also have a variation of the to complete such calculations at the same time to abacus known as the Soroban where the only minimise the mental calculations involved.

However, the latter analogy may be less accurate as an electronic calculator would compute an answer when a series of buttons are pressed and requires less human input to perform the calculation compared to an abacus. -
Transnational Mathematics and Movements: Shiing- Shen Chern, Hua Luogeng, and the Princeton Institute for Advanced Study from World War II to the Cold War1

It argues that Chern’s and Hua’s motivations and choices in regard to their transnational movements between China and the US were more nuanced and multifaceted than what is presented in existing accounts, and that socio-political factors combined with professional-personal ones to shape their decisions. The paper further uses their experiences to demonstrate the importance of transnational scientific interactions for the development of science in China, the US, and elsewhere in the twentieth century.

Definitions and Nondefinability in Geometry 475 2
Definitions and Nondefinability in Geometry1 James T. Smith Abstract. Around 1900 some noted mathematicians published works developing geometry from its very beginning. They wanted to supplant approaches, based on Euclid’s, which han- dled some basic concepts awkwardly and imprecisely. They would introduce precision re- quired for generalization and application to new, delicate problems in higher mathematics. Their work was controversial: they departed from tradition, criticized standards of rigor, and addressed fundamental questions in philosophy. This paper follows the problem, Which geo- metric concepts are most elementary? It describes a false start, some successful solutions, and an argument that one of those is optimal. It’s about axioms, definitions, and definability, and emphasizes contributions of Mario Pieri (1860–1913) and Alfred Tarski (1901–1983). By fol- lowing this thread of ideas and personalities to the present, the author hopes to kindle interest in a fascinating research area and an exciting era in the history of mathematics. 1. INTRODUCTION. Around 1900 several noted mathematicians published major works on a subject familiar to us from school: developing geometry from the very beginning. They wanted to supplant the established approaches, which were based on Euclid’s, but which handled awkwardly and imprecisely some concepts that Euclid did not treat fully. They would present geometry with the precision required for general- ization and applications to new, delicate problems in higher mathematics—precision beyond the norm for most elementary classes. Work in this area was controversial: these mathematicians departed from tradition, criticized previous standards of rigor, and addressed fundamental questions in logic and philosophy of mathematics.2 After establishing background, this paper tells a story about research into the ques- tion, Which geometric concepts are most elementary? It describes a false start, some successful solutions, and a demonstration that one of those is in a sense optimal. -
Models in Geometry and Logic: 1870-1920 ∗
Models in Geometry and Logic: 1870-1920 ∗ Patricia Blanchette University of Notre Dame 1 Abstract Questions concerning the consistency of theories, and of the independence of axioms and theorems one from another, have been at the heart of logical investigation since the beginning of logic. It is well known that our own contemporary methods for proving independence and consistency owe a good deal to developments in geometry in the middle of the nineteenth century, and especially to the role of models in estab- lishing the consistency of non-Euclidean geometries. What is less well understood, and is the topic of this essay, is the extent to which the concepts of consistency and of independence that we take for granted today, and for which we have clear techniques of proof, have been shaped in the intervening years by the gradual de- velopment of those techniques. It is argued here that this technical development has brought about significant conceptual change, and that the kinds of consistency- and independence-questions we can decisively answer today are not those that first motivated metatheoretical work. The purpose of this investigation is to help clarify what it is, and importantly what it is not, that we can claim to have shown with a modern demonstration of consistency or independence.1 ∗This is the nearly-final version of the paper whose official version appears in Logic, Methodology, and Philosophy of Science - proceedings of the 15th International Congress, edited by Niiniluoto, Sepp¨al¨a,Sober; College Publications 2017, pp 41-61 1Many thanks to the organizers of CLMPS 2015 in Helsinki, and also to audience members for helpful comments.
