The Open Secret Of Male Prostitution In The Philippines: A Descriptive Phenomenological Study

This study attempts to describe the lived experiences of the male teenager and adult sex workers of Cebu City, Philippines in terms of their attitude and behavior, reasons for indulging in prostitution, clientele, challenges, and coping mechanisms. A descriptive phenomenological design with personal interviews and a naturalistic paradigm were used to gather data from the purposely chosen participants. Triangulation was carried to validate the participants’ responses. Results show that male teenagers and adult sex workers tend to be covert of their work, neglectful of others’ judgment about prostitution, and view prostitution as any other job. Poverty, lack of parental guidance and support, early exposure to pornography, peer pressure, unemployment due to poor educational attainment were their reasons for indulging in prostitution. They catered to random bisexual and transgender clients. They encountered various problems such as awkwardness with their partner, financial instability, public distress, and fear of HIV transmission. Getting motivation from the money as payment, sustaining their own and family‘s needs were their means of coping up. Resorting into prostitution is a story to tell. Male teenagers and adult sex workers experienced poverty as their common denominator of indulging in prostitution. Though they are condemned by society for entering prostitution they intend to provide and suffice their needs. Prostitution, therefore, is a means to survive amidst living in poverty

Prolongation of overall treatment time as a cause of treatment failure in early breast cancer: an analysis of the UK START (Standardisation of Breast Radiotherapy) trials of radiotherapy fractionation

AbstractBackgroundTests of tumour treatment time effect in patients prescribed post-operative radiotherapy for early breast cancer have focussed on time to start of radiotherapy rather than overall treatment time. The START randomised trials of radiotherapy fractionation provide an opportunity to directly estimate the effect of treatment acceleration.MethodsBetween 1986 and 2002, a total of 5861 women with early breast cancer were recruited into the UK START pilot (START-P), START-A and START-B randomised trials. START-P and START-A tested 13 fractions of 3.0–3.3Gy against 25 fractions of 2.0Gy with a fixed treatment duration of 5weeks for all schedules; START-B tested 15 fractions of 2.67Gy in 3weeks against 25 fractions of 2.0Gy over 5weeks. Estimates of the effect of length of treatment for local–regional relapse and for a measure of late normal tissue effects (change in photographic breast appearance, for patients following breast conserving surgery) were obtained from Cox proportional hazards regression analyses stratified according to trial.ResultsAt a median follow-up of 10years, 444/5831 (7.6%) patients with data available had a local–regional relapse, and 1135/3185 (35.6%) had mild or marked change in photographic breast appearance by 5years. Adjusting for prognostic factors, the estimate of the overall treatment time effect for local–regional relapse was 0.60Gy/day (95%CI 0.10 to 1.18Gy/day, p=0.02), and 0.14Gy/day (95%CI −0.09 to 0.34Gy/day, p=0.29) for change in photographic breast appearance.ConclusionsCombined analysis of the START trials generates the hypothesis that overall treatment time is a significant determinant of local cancer control after adjuvant whole breast radiotherapy, with approximately 0.6Gy per day ‘wasted’ in compensating for tumour cell proliferation

A Gyrochronology and Microvariability Survey of the Milky Way's Older Stars Using Kepler's Two-Wheels Program

Even with the diminished precision possible with only two reaction wheels, the Kepler spacecraft can obtain mmag level, time-resolved photometry of tens of thousands of sources. The presence of such a rich, large data set could be transformative for stellar astronomy. In this white paper, we discuss how rotation periods for a large ensemble of single and binary main- sequence dwarfs can yield a quantitative understanding of the evolution of stellar spin-down over time. This will allow us to calibrate rotation-based ages beyond ~1 Gyr, which is the oldest benchmark that exists today apart from the Sun. Measurement of rotation periods of M dwarfs past the fully-convective boundary will enable extension of gyrochronology to the end of the stellar main-sequence, yielding precise ages ({\sigma} ~10%) for the vast majority of nearby stars. It will also help set constraints on the angular momentum evolution and magnetic field generation in these stars. Our Kepler-based study would be supported by a suite of ongoing and future ground-based observations. Finally, we briefly discuss two ancillary science cases, detection of long-period low-mass eclipsing binaries and microvariability in white dwarfs and hot subdwarf B stars that the Kepler Two-Wheels Program would facilitate.Comment: Kepler white pape

Charge and Spin Transport Anisotropy in Nanopatterned Graphene

Anisotropic electronic transport is a possible route towards nanoscale circuitry design, particularly in two-dimensional materials. Proposals to introduce such a feature in patterned graphene have to date relied on large-scale structural inhomogeneities. Here we theoretically explore how a random, yet homogeneous, distribution of zigzag-edged triangular perforations can generate spatial anisotropies in both charge and spin transport. Anisotropic electronic transport is found to persist under considerable disordering of the perforation edges, suggesting its viability under realistic experimental conditions. Furthermore, controlling the relative orientation of perforations enables spin filtering of the transmitted electrons, resulting in a half-metallic anisotropic transport regime. Our findings point towards a co-integration of charge and spin control in a two-dimensional platform of relevance for nanocircuit design. We further highlight how geometrical effects allow finite samples to display finite transverse resistances, reminiscent of Spin Hall effects, in the absence of any bulk fingerprints of such mechanisms, and explore the underlying symmetries behind this behaviour.Comment: 11 pages, 6 figure

A cross-sectional study of physical activity and sedentary behaviours in a Caribbean population: combining objective and questionnaire data to guide future interventions

Abstract Background Current understanding of population physical activity (PA) levels and sedentary behaviour in developing countries is limited, and based primarily on self-report. We described PA levels using objective and self-report methods in a developing country population. Methods PA was assessed in a cross-sectional, representative sample of the population of Barbados (25–54 years), using a validated questionnaire (RPAQ) and individually calibrated combined heart rate and movement sensing monitors. The RPAQ collects information on recalled activity in 4 domains: home, work, transport, and leisure. Physical inactivity was defined according to World Health Organization (WHO) guidelines; sedentary lifestyle was defined as being sedentary for 8 h or more daily; PA overestimation was defined as perceiving activity to be sufficient, when classified as ‘inactive’ by objective measurement. Results According to objective estimates, 90.5 % (95 % CI: 83.3,94.7) of women and 58.9 % (48.4,68.7) of men did not accumulate sufficient activity to meet WHO minimum recommendations. Overall, 50.7 % (43.3,58.1) of the population was sedentary for 8 h or more each day, and 60.1 % (52.8,66.9) overestimated their activity levels. The prevalence of inactivity was underestimated by self-report in both genders by 28 percentage points (95 % CI: 18,38), but the accuracy of reporting differed by age group, education level, occupational grade, and overweight/obesity status. Low PA was greater in more socially privileged groups: higher educational level and higher occupational grade were both associated with less objectively measured PA and more sedentary time. Variation in domain-specific self-reported physical activity energy expenditure (PAEE) by educational attainment was observed: higher education level was associated with more leisure activity and less occupational activity. Occupational PA was the main driver of PAEE for women and men according to self-report, contributing 57 % (95 % CI: 52,61). The most popular leisure activities for both genders were walking and gardening. Conclusions The use of both objective and self-report methods to assess PA and sedentary behaviour provides important complementary information to guide public health programmes. Our results emphasize the urgent need to increase PA and reduce sedentary time in this developing country population. Women and those with higher social economic position are particularly at risk from low levels of physical activity

Biochemical Changes of Chickpea Genotypesbefore and After Infestation of Pulse Beetle, Callosobruchus Chinensis L. (Coleoptera: Bruchidae) During Storage

The pulse beetle is a field-to-store pest as its infestation on pulses often begins in the field itself as adults lay eggs on mature pods and when such seed is harvested and stored, the pest population increases rapidly and results in total destruction within a short period of 3-4 months. Keeping in view,varietal screening of fifty chickpea genotypes was carried outin the storage laboratory, Department of Entomology, OUAT, BBSR and the performance of the genotypes was assessed based on various biological parameters of test insect, damage and infestation by C. chinensis. The results indicated that none of the genotypes was completely resistant to pest attack whereas 4 genotypes (Himachal Chana 1, Dheera (NBeG-47), JG-14 and Dilaji) were found moderately resistant, 8 genotypes (Phule Vikram, JG 11, ICCV-181108, ICCV-181107, ICCV-181605, C-18203, C-18205 and C-18252) were moderately susceptible,11 genotypes (RVG-204, RVG-203, JAKI-9218, Pratap Chana, Bharati, ICCC 4, ICCV-181106, ICCV-181612, C-18206, ICCV-181101 and Radhey) were susceptible and 27 genotypes (NBeG-49, Himachal Chana 2, JG-16, JG-130, CO 4, Vishal, Kranthi, NBeG-3, ICCV-14102, ICCV-171117, C-18175, ICCV-181611,ICCV-14106, Kalahandi Local, ICC 3137, ICCL 86111, C-19162, C-19168,GNG 2207, BG 3043, GG 3, Birsa Chana 3, C 19199, RSG 963, C 19200, KPG 59and NBeG 119) were noticed to be highly susceptible. The bio-chemicalconstituents analyzed in the present studies viz., protein, phenol, ash and fibre contents of the genotypes contributed to the resistance / susceptibility of C. chinensis. Among the biochemical parameters, protein exerted significant positive effect whereas phenol, ash and fibre contents exhibited negative influence on pest infestation and development
