A qualitative study to explore the value of videotaped perceptions of research participants and stakeholders for use in analysing evidence for policy-making in the Gambia.Untitled Item
No full textThis the dissertation
of Jamie Guth, submitted in partial fulfilment of the requirements for the
degree of Master of Public Health, University of Liverpool, August 2017.
Background
The field of
evidence-informed policy-making (EIPM) is limited and has often missed valuable
types of evidence not included in these theories. Policymakers want to know how
the target user or community feels about an innovation, and to see and hear how
involved and committed they are. A study in the Gambia offered the opportunity
to test videotaped interviews of research participants as a way of sharing
local context at a policy panel discussion of the research results.
Aim
To explore
the acceptability and value of videotaped interviews of study participants as
an additional tool to provide research results to policy-makers and
practitioners.
Methods
This
qualitative study used semi-structured, in-depth interviews to explore policymakers’
views on the use of videotaped interviews. Purposive sampling led to the recruitment
of all 16 individuals who met inclusion criteria from the sample.
Results
The
participants found that the video provided credibility and reliability to
research; context and community acceptance; and clarification of barriers and
access issues. Their experience also led to recommendations on video length and
depth of content for future use, and how a deliberative discussion can increase
understanding of the issues.
Conclusion
This study
provides the first analysis of video for this purpose. The video provided
unique information to the panel members that strengthened memory and
understanding of the findings, as well as commitment to taking up the research
findings.</p
Polynomial methods in combinatorics
No full textThis book explains some recent applications of the theory of polynomials and algebraic geometry to combinatorics and other areas of mathematics. One of the first results in this story is a short elegant solution of the Kakeya problem for finite fields, which was considered a deep and difficult problem in combinatorial geometry. The author also discusses in detail various problems in incidence geometry associated to Paul Erdős's famous distinct distances problem in the plane from the 1940s. The proof techniques are also connected to error-correcting codes, Fourier analysis, number theory, and differential geometry. Although the mathematics discussed in the book is deep and far-reaching, it should be accessible to first- and second-year graduate students and advanced undergraduates. The book contains approximately 100 exercises that further the reader's understanding of the main themes of the book. Some of the greatest advances in geometric combinatorics and harmonic analysis in recent years have been accomplished using the polynomial method. Larry Guth gives a readable and timely exposition of this important topic, which is destined to influence a variety of critical developments in combinatorics, harmonic analysis and other areas for many years to come. -Alex Iosevich, University of Rochester, author of "The Erdős Distance Problem" and "A View from the Top" It is extremely challenging to present a current (and still very active) research area in a manner that a good mathematics undergraduate would be able to grasp after a reasonable effort, but the author is quite successful in this task, and this would be a book of value to both undergraduates and graduates. -Terence Tao, University of California, Los Angeles, author of "An Epsilon of Room I, II" and "Hilbert's Fifth Problem and Related Topics"
Polarization in the Sunyaev-Zeldovich effect
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2003.Includes bibliographical references (p. 121-125).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.A novel covariant formalism for the treatment of the transfer and Compton scattering of partially polarized light is presented. In this approach, the polarization state of a light beam is described by a tensor constructed from the time average of quadratic products of the electric field components in a local observer frame. This leads naturally to a covariant description which is ideal for calculations involving the boosting of polarized light beams between Lorentz frames, and is more flexible than the traditional Stokes parameter approach in which a separate set of polarization basis vectors is required for each photon. The covariant kinetic equation for Compton scattering of partially polarized light by relativistic electrons is obtained in the tensor formalism by a heuristic semi-classical line of reasoning. The kinetic equation is derived first in the electron rest frame in the Thomson limit, and then is generalized to account for electron recoil and allow for scattering from an arbitrary distribution of electrons. This formalism is applied to a calculation of the relativistic corrections to the spectral distortions imprinted in the intensity and polarization of the cosmic microwave background radiation (CMB) by inverse Compton scattering in clusters of galaxies (the Sunyaev-Zeldovich effects). We develop a Monte Carlo method for simulating these effects, based on the tensor formalism and kinetic equation. We also consider the use of the polarization signal generated by scattering of the CMB from distant clusters as a probe of cosmological perturbations.(cont.) Such observations allow an indirect measure of the CMB quadrupole as seen on the last scattering surfaces of observers at nonzero redshift. The statistical properties of this signal in a simple cosmological model are derived. We demonstrate that measurements of this signal would yield more information than is available from observations of the CMB anisotropies on our sky, and would potentially allow more precise measurement of cosmological parameters and the primordial power spectrum of density fluctuations.by Jamie Portsmouth.Ph.D

No full textSuzie Guth : Aktualität von W. F. Whyte. Ordnung und Unordnung in den Stadtviertelbanden.
Der Text will die Stellung von W. F. Whyte untersuchen, dem Verfasser von "Street corner society", im Vergleich zur Chicagoschule. Dazu wurden die persönlichen Archiven und Schriften des Autors untersucht, und besonders das von ihm nach seiner Doktordissertation verfasste Manuskript, das vom Prüfungsausschuss im Jahre 1942 verlangt wurde. Hier Stellt sich die Frage, warum er diese Zugehörigkeit und das Konzept der "sozialen Desorganisation" widerlegt. Es werden die von Whyte zitierten Autoren konfrontiert und die von ihm dazu verfasste Analyse. Die einseitige Interpretation der sozialen Desorganisation und die Furcht vor der Stigmatisierung der Slumsbewohner verleiten Whyte dazu, die Auswirkungen der sozialen Auflösung zu mindern und den Vorrang der Solidarität in der sozialen Ordnung der Strasse zu bekräftigen.Suzie Guth : Actuality of W. F. Whyte. Order and disorder in street district.
The purpose of this text is to examine the position of W. F. Whyte, author of "Street corner society", in relation to the Chicago school, by consulting the author's written work and personal archives, in particular the handwritten work following his thesis examination, requested by the jury in 1942. The question is to understand why he refuted his adherence to this sociology and its concept of "social disorganization". The authors quoted by W. F. Whyte are confronted together with the analyses he made. The unilateral interpretation of social disorganization, the fear of stigmatizing those who live in slums, led W. F. Whyte to minimize the effects of social recomposition and to affirm the preeminence of solidarity in the street social order.Le texte a pour objet d'examiner la position de W.F. Whyte, auteur de "Street corner society", par rapport à l'École de Chicago. Pour ce faire, on a consulté les écrits et les archives personnelles de l'auteur, essentiellement le manuscrit rédigé après la soutenance de sa thèse, exigé par le jury en 1942. La question est posée de savoir pourquoi il réfute cette appartenance, ainsi que le concept de « désorganisation sociale ». On confronte les auteurs cités par W.F. Whyte et l'analyse qu'il en a fait. L'interprétation unilatérale de la désorganisation sociale, la crainte d'une stigmatisation des habitants des "slums" entraînent W.F. Whyte à minorer les effets de recomposition sociale et à affirmer la prééminence de la solidarité dans l'ordre social de la rue.Suzie Guth : Actualidad de W. F. Whyte.

La interpretación unilateral de la desorganización social, el temor de una estigmatización de los habitantes de los slums obligan a W. F.

particleShear: Discrete Python particle simulation with digital rheology and stress tensor evaluation
No full textparticleShear: Python package for particle shear simulation
This package provides a discrete particle simulation kit for having multiple spheres interacting. The spheres (i.e. 2D circles) interact by mutual elastic repulsion and tangential friction upon contact, but can also be crosslinked together. In addition to the elementary implementation of the interacting particles, it is also possible to define rheological experiments where the spheres are exposed to sinusoidally varying displacement conditions on the boundaries. We paid particular attention to avoid pitfalls that generate asymmetric stress tensors.
Acknowledgement: Thanks from the author go to Fabien Bonini and Joé Brefie-Guth for package testing, and to Daniel Lyobenov for initial help with simulation setup.
This repository archives the releases of the source code hosted at https://github.com/tbgitoo/particleShear. The package is available through the Python package server (see https://pypi.org/project/particleShear/1.0.2/). It can be installed automatically in python via
pip3 install particleShear
In some installations, the command may also be pip install particleShear; the minimal version of Python is 3.
Egyptian Humour and Satire in Mona Prince’s The Life and Adventures of Professor M.
No full textAlthough it may seem absurd, it is no exaggeration to say that humour is a very serious matter in Egypt, where dozens of intellectuals have analysed this phenomenon, often linking it to their national identity. This article presents various opinions on Egyptian satire to introduce a 2015 novel by Mona Prince, one of the Egyptian writers of the 1990s generation. In 2012, the author published a memoir of the January 25 Revolution. This study tries to explain the relationship between her political activism and her literary career; the role of humour in her œuvre; and how she deals with gender and religious issues in her 2015 work, which is also autobiographic. Moreover, since the novelist wrote the text between 2008 and 2014, this article offers some notes on satiric literature in pre- and post-2011 Egypt
al-Rawiyat de Maha Hasan: métamorphose et réincarnation comme dernière tentative pour préserver la vie
No full textAl-Rawiyat (The Storytellers) is a metafictional novel written by Syrian author Maha Hasan in 2014. The text contains two intertwined levels: the first is the inner monologue of a woman who is writing a novel; the second is represented by the stories of the characters she creates and that become themselves storytellers. In this text Maha Hasan explores the art of storytelling through multiple stories and many female characters. Ḥasan’s storytellers often live in parallel and imaginary worlds, in a permanent state of metamorphosis and perpetual reincarnation. The stories they live and narrate represent their last attempt to preserve life in an inhuman time that changes at a spasmodic rhythm and generates simultaneous events with contradictory effects. This novel translates into fiction the rapid changes of the present period, which—as affirmed by Rosi Braidotti in her Metamorphoses—does not truncate the brutality of power relations, but at deeper view, intensifies them to their point of implosion
