Selling goods or providing services in public spaces is one of the most accessible occupations for many individuals living in poverty in today’s world. However, most street vendors conduct their businesses by disobeying laws that prohibit this kind of work. Drawing on field data on street vendors in the city of Bogotá, Colombia, this article ethnographically explores vendors’ ideas, perceptions, a

We study the operation of an 8.5 mu m quantum cascade laser based on GaInAs/AlInAs lattice matched to InP using three different simulation models based on density matrix (DM) and non-equilibrium Green's function (NEGF) formulations. The latter advanced scheme serves as a validation for the simpler DM schemes and, at the same time, provides additional insight, such as the temperatures of the sub-ba

Athletes constantly report experiences of momentum during athletic contests, and they consider momentum as being an important factor for the outcome of a competition. However, researchers trying to capture momentum with quantitative methods see themselves confronted with inconclusive results. To explain this gap between athletes’ belief and results from quantitative data, it is hypothesised that m

Inter-comparison of results from two kinds of aerosol systems in the CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on a Instrument Container) passenger aircraft based observatory, operating during intercontinental flights at 9-12 km altitude, is presented. Aerosol from the lowermost stratosphere (LMS), the extra-tropical upper troposphere (UT) and the tropical mid t

Summary The CAG repeat in the androgen receptor (AR) has been widely studied in association with male infertility, but the results are conflicting. In a recent meta-analysis, infertile men had <1 repeat longer CAG stretch than fertile men when analysed in a linear regression model assuming that AR function diminishes with increasing CAG length. However, in vitro, a non-linear activity pattern was

Binding of platelet-derived growth factor (PDGF) to its receptors leads to the activation of members of the Src family of protein tyrosine kinases. We show here that Fyn, a member of the Src family, is phosphorylated on Tyr28 in the unique N-terminal part of the molecule after interaction with the intracellular domain of the PDGF beta-receptor. Activated Fyn furthermore undergoes autophosphorylati

Healthy human skeletal muscles are composed of two distinguishable types of fibre, apparently randomly arranged within fascicles (bundles of fibres surrounded by connective tissue). Large groups of fibres of the same type indicate a neurogenic muscle disorder. An objective method for detecting nonrandom arrangements of fibres could improve the diagnosis of such disorders, particularly at an early

An area of considerable interest in second language (L2) acquisition is the difficulties learners face with the acquisition of articles. This article examines the role of prosody in the acquisition of articles by an endstate L2 English speaker focusing on the free morphemes the and a. In order to analyse the articles produced by a Turkish speaker named SD, we used the Praat (Boersma and Weenink, 2

OBJECTIVE: To investigate a marker of tumor proliferation, Ki-67, and telomerase expression in glioblastoma multiforme and to compare the results of different mainly quantitative assessments, in relation to age and survival rates. METHODS: Immunohistochemical stainings of Ki-67 and hTERT were evaluated in 39 formaldehyde-fixed, paraffin-embedded surgical samples of glioblastoma multiforme diagnose

The Zn-61(30)31 isotope has been produced at the Oak Ridge National Laboratory in the fusion-evaporation reaction Ca-40(Mg-24, 2pn)Zn-61 at 104 MeV. The experimental set-up allowed gamma-rays to be detected in the CLARION Ge detector array in coincidence with the detection of recoiling nuclei in the focal plane at the end of the recoil mass spectrometer. This provides a unique identification of ga

All natural populations fluctuate in abundance and age structure through time; understanding why they do so is a critical step towards their effective management and conservation. However, the long-term data sets needed for such an understanding are rarely available, especially for tropical organisms. A 17-year capture-mark–recapture study yielded detailed information on the demography of water py

We examine strategic self-ignorance—the use of ignorance as an excuse to overindulge in pleasurable activities that may be harmful to one’s future self. Our model shows that guilt aversion provides a behavioral rationale for present-biased agents to avoid information about negative future impacts of such activities. We then confront our model with data from an experiment using prepared, restaurant

Målet med detta arbete var att studera de termodynamiska och strukturella egenskaperna hos polyetylenglykol genom att tillämpa en kombination av experiment och datorsimuleringar. Den experimentella huvudtekniken var membran osmometri och datorsimuleringarna baserades på Monte Carlo metoden. Polyetylenglykol även förkortat PEG är en neutral linjär polymer med amfifilisk karaktär, vilket menas attThe aim of this thesis was to evaluate the accuracy of a one-parameter non-virial scaling equation of state (EOS) for polyethylene glycol in water by Cohen et al. through osmotic pressure measurements using membrane osmometry and Monte Carlo simulations. PEG20 was set as the reference system and the polymer chain length effect was investigated through simulations of PEG10 and PEG35. For PEG35 expe

dis thesis attempts to use qualitative research and sociological analysis to explore how demilitarization, which TEMPhas lasted for decades, may TEMPhas an impact on development in recent years. Mainly based on literature review and data analysis, dis thesis chose Costa Rica as teh background, for revealing national education status - as teh research object - to speculate on how demilitarization T

This chapter analyses humour from an emotion sociological perspective, linking humour to power, status, and group solidarity. It draws from about 300 observed trials and interviews with 43 judges and 41 prosecutors from four Swedish districts courts. Humour is sometimes skilfully used as a strategy to ease tension, relieve boredom or to reprimand. It is initiated/allowed by the judge, but high-staThis chapter analyses humour from an emotion sociological perspective, linking humour to power, status, and group solidarity.

There is a widespread perception among scholars and policymakers that a link exists between entrepreneurship and GDP growth. Based on data from 33 OECD countries between 2001 and 2011, this essay aims to empirically investigate the impact of entrepreneurship on economic growth. More specifically, this essay seeks to analyze how entrepreneurship contributes to different types of economic growth. In

Populärvetenskaplig sammanfattning ”Byggnader och anläggningar ska lokaliseras och utformas på ett miljöanpassat sätt…”, så lyder riksdagens defintion av miljökvalitetsmålet God bebyggd miljö (Miljömål, 2016a). Företag som Boklok är en viktig del av utvecklingen mot en god bebyggd miljö i Sverige. En god vardagsmiljö utgör en av delarna i miljökvalitetsmålet vilket bland annat innefattar ett variHousing today stands for 40 % of Swedens total energy use and therefore the industry has a big environmental impact (Miljömål, 2016a). This is not only an important issue due to the environmental impact, it also has a high importance for the society due to the current housing shortage that is prevailing in Sweden. It is important to find a way to be able to industrialize house building with the lo

This thesis examines the ideologies and moral values regarding sexuality and gender within the United States national realm of Sexual and Reproductive Health and Rights (SRHR); and furthermore what how these ideologies and morals are translated into development policy. Through the method interrogative insertion, I have explored in the U.S. President´s Emergency Plan for AIDS Relief (PEPFAR). And t
