Extracting Personal Behavioral Patterns from Geo-Referenced Tweets

This paper presents an exploratory study of the potential of geo-referenced Twitter data for extracting knowledge about significant personal places, behaviors and potential interests of people. The study was done analysing two months’ worth of tweets from residents of the greater Seattle area

Shuttle/spacelab MMAP/electromagnetic environment experiment phase B definition study

Progress made during the first five months of the Phase B definition study for the MMAP/Electromagnetic Environment Experiment (EEE) was described. An antenna/receiver assembly has been defined and sized for stowing in a three pallet bay area in the shuttle. Six scanning modes for the assembly are analyzed and footprints for various antenna sizes are plotted. Mission profiles have been outlined for a 400 km height, 57 deg inclination angle, circular orbit. Viewing time over 7 geographical areas are listed. Shuttle interfaces have been studied to determine what configuration the antenna assembly must have to be shared with other experiments of the Microwave Multi-Applications Payload (MMAP) and to be stowed in the shuttle bay. Other results reported include a frequency plan, a proposed antenna subsystem design, a proposed receiver design, preliminary outlines of the experiment controls and an analysis of on-board and ground data processing schemes

Victor or victim? Foregrounding the independent escort experience outside of the polarised debate

The sex worker as a sociocultural ‘phenomenon’ occupies a liminal space, simultaneously absent from sociopolitical acceptability yet ever present in often inflammatory, ‘condemn/celebrate’ discourses. In this paper we aim to contribute to a destabilising of the dichotomisation of these representations by referring to the lived experience of independent escorts. In addition we attempt to contextualize the sex worker in consumer capitalism through which notions of choice and exploitation, that arise from both sides of the ‘condemn’/’celebrate’ debate, are rendered oblique. We draw upon the author’s own experience of being an escort as well as accounts from a popular escort internet forum1 to illustrate the issues escorts share with women as a wider social demographic, including violence and abuse, appearance pressures, and economic hardship. By situating escorting as a form of self-employment labour, within the practical reality of neoliberal, consumer capitalism, we aid in the nuancing of the debate, foregrounding the escort experience over prior, moral ideologies. We also promote the merging of the academic debate surrounding the sex work industry, with the grassroots debate that forum member escorts have on a daily basis. We conclude it is important to demystify and destigmatise escorts so they are not regarded as 'victims or victors' or other grotesque parodies, but a real, diverse people and members of a labour force

A New 5 Flavour NLO Analysis and Parametrizations of Parton Distributions of the Real Photon

New, radiatively generated, NLO quark (u,d,s,c,b) and gluon densities in a real, unpolarized photon are presented. We perform three global fits, based on the NLO DGLAP evolution equations for Q^2>1 GeV^2, to all the available structure function F_2^gamma(x,Q^2) data. As in our previous LO analysis we utilize two theoretical approaches. Two models, denoted as FFNS_{CJK}1 & 2 NLO, adopt the so-called Fixed Flavour-Number Scheme for calculation of the heavy-quark contributions to F_2^gamma(x,Q^2), the CJK NLO model applies the ACOT(chi) scheme. We examine the results of our fits by a comparison with the LEP data for the Q^2 dependence of the F_2^gamma, averaged over various x-regions, and the F_2,c^gamma. Grid parametrizations of the parton densities for all fits are provided.Comment: 49 pages, 27 postscript figures; FORTRAN programs available at http://www.fuw.edu.pl/~pjank/param.htm

The appearance potency of gay and straight men’s websites

Gay men's greater body dissatisfaction compared to straight men has been explained as a result of gay men’s more 'appearance potent' subculture. This study aimed to critically appraise this explanation by assessing images of men and women for their physical characteristics and objectification across 8 popular gay and straight men's dating and porn websites. 1,415 images of men and 715 images of women across the website’s main pages were coded. Results showed that the gay men's websites featured more images of men that were appearance-ideal, nude, and sexualized in comparison to the straight men's websites. With the converse true for straight men’s websites. These results highlight the continuing need to develop and provide interventions that critique the appearance potency of popular media, particularly so for gay men

Optoelectronic comb generation and cross-injection locking of photonic integrated circuit for millimetre-wave generation

We demonstrate how a monolithically integrated heterodyne source was used for a 33.6 GHz signal generation using an optical solution by a combination of cross-optical injection locking inside the chip and electrical injection locking at the RF signal 7th sub-harmonic

Light except Lupita: The representation of Black women in magazines

Psychology is dominated by White Westerners. Subsequently researchers have minimised or ignored Black women’s body dissatisfaction. This study sought to account for the intersection of racism and body dissatisfaction by coding the representation of Black women, the number of appearance adverts and articles across 8 issues of mainstream women’s magazines (Elle, Vogue) and Black women’s magazines (Essence and Ebony) from 2015/16. The majority of Black women featured in the magazines (N = 539) were young (83 per cent) slim (62 per cent), had light skin (66 per cent) and straight hair (60 per cent). Compared to the Black women’s magazines, Black women were rarely represented in the mainstream women’s magazines (N = 64, 11 per cent) and when they were represented generally had straighter hair, narrow noses and lighter skin tones. This study underscores the need for psychology, including body dissatisfaction researchers, to recognise (and challenge) the intersections of racism with other impacts to wellbeing including body dissatisfaction

"Peeling property" for linearized gravity in null coordinates

A complete description of the linearized gravitational field on a flat background is given in terms of gauge-independent quasilocal quantities. This is an extension of the results from gr-qc/9801068. Asymptotic spherical quasilocal parameterization of the Weyl field and its relation with Einstein equations is presented. The field equations are equivalent to the wave equation. A generalization for Schwarzschild background is developed and the axial part of gravitational field is fully analyzed. In the case of axial degree of freedom for linearized gravitational field the corresponding generalization of the d'Alembert operator is a Regge-Wheeler equation. Finally, the asymptotics at null infinity is investigated and strong peeling property for axial waves is proved.Comment: 27 page
