Women in the age of andromation : challenges for feminisms in the fourth industrial revolution

Industrial automation poses challenges to policymakers as it could lead to long-term unemployment and rising inequality. Due to occupational segregation, mainly women work in the productive sectors most at risk of becoming robotized. International institutions, including the United Nations’ International Labor Organization, the Commission on the Status of Women, and the World Economic Forum have outlined policy proposals to curtail the adversities that automation poses for women...La automatización industrial posa desafíos de gobernanza por su capacidad de producir desempleo y desigualdad a largo plazo. La segregación ocupacional por género sitúa a las mujeres en los sectores productivos con mayor riesgo de ser robotizados. Instituciones internacionales como la Organización Internacional del Trabajo, la Comisión de las Naciones Unidas por el Estatus de las Mujeres, y el Foro Económico Mundial han formulado propuestas de política pública para mitigar las adversidades que la automatización podría producir para las mujeres..

Evaluation of Daylight Parameters on the Basis Simulation Model For the Tropical Climate

Use of natural daylight in the building is energy saving with respect to illumination levels and health benefits. However in, the hot and dry climatic zone increase in daylight availability may result into thermal ingress. This might lead to excess energy conservation. The aim of this paper is to evolve the methodology which could be used as a pre design tool for assessing the lighting provisions and thermal performance of spaces within buildings adopted by designers during the design process. The field measurements were conducted on the liveable spaces of a dwelling unit of the Nagpur region. Simulation studies using Ecotect Analysis 2011 was conducted for both illumination and thermal energy. The field measurements were compared with the simulated results. It has been found that the percentage difference (PD) between the Ecotect measurements (EM) and field measurements (FM) for both thermal loads and an illuminance level was less than 15%, the simulated model was considered precise for further study. The result imply that the simulated model would be ample for designers to evaluate the parameters associated to wall to window ratio, shading devices with respect to orientation of the building which helps to achieve the optimum useful daylight index

Assessment of Daylight into the Residential Building According to the Floor Levels for Hot and Dry Climatic Zone

It is very important to use the daylight in the building design, which is allowed by the windows into the buildings, to reduce the energy consumption. However, on the other hand, the performance of daylight varies according to the floor levels of the building. This research focused on the investigation of the correlation between the performance of daylight and window areas according to floor levels through field measurements and simulation experiments in the residential building. The aim of this research is to derive the adequate window areas according to the floor levels with respect to the orientation of the residential building to achieve the optimum level of daylight and indoor temperature in the livable areas of a residential building. The case selected is residential building from Nagpur region, of Central India. It has a hot and dry climate. The evaluation of daylight level has been done with selected parameters like percentages of Carpet Area to Window Ratio (CAWR) and Orientation by using daylight metrics, namely Useful Daylight Illuminance (UDI) (with Daysim and Radiance analysis tools plug-in Ecotect 2011 software). The findings of this research are the adequate area of window according to floor levels with respect to the orientation in the livable areas of the residential building

Effects of microwave heating on the thermal states of biological tissues

A mathematical analysis of microwave heating equations in one-dimensional multi-layer model has been discussed. Maxwell's equations and transient bioheat transfer equation were numerically calculated by using finite difference method to predict the effects of thermal physical properties on the transient temperature of biological tissues. This prediction of the temperature evolution in biological bodies can be used as an effective tool for thermal diagnostics in medical practices. Key words: Microwave heating, Maxwell's equations, bioheat, multi layer. African Journal of Biotechnology Vol.2(11) 2003: 453-45

Hall current and joule heating effects on peristaltic flow of a sisko fluid with mild stenosis through a porous medium in a tapered artery with slip and convective boundary conditions

This work is arranged to investigate the Hall current and Joule heating effects on peristaltic flow of a Sisko fluid through a porous medium. The streaming is through tapered artery with mild stenosis. The influences of radiative heat transfer and chemical reactions are taken in consideration. Convective conditions are considered for heat and mass transfer. However, the slip conditions are adopted for the velocity distribution. The combined effects of viscous dissipation and radiation in energy expression are presented. Soret and Dufour features produce the coupled differential systems. The presumptions of the long wavelength and low Reynolds number are adopted to examine the governing equations of motion. The analytical solutions of these equations are given by two methods. The first one uses regular perturbation technique, which based on small wave number for small artery. The second one is based on utilizing the Homotopy perturbation technique. The approximate analytical solutions of the pressure rise and friction force are predestined along a numerical integration. The influences of various physical parameters of the problem are debated and depicted graphically through a set of figures. It is found that the axial velocity increases with the increase of Hall current parameter and with the decrease of Hartmann number. Also, it can be observed that the Brickmann number and Dufour number give rise to the fluid temperature. Meanwhile, reverse effect is observed towards concentration for both Schmidt number and chemical reaction number. Furthermore, the stream lines are graphically shown

Magnetohydrodynamic Peristaltic motion with heat and mass transfer of a Jeffery fluid in a tube through porous medium

The effects of radiation on the unsteady flow of an incompressible non-Newtonian (Jeffrey) fluid through porous medium have been discussed. The thermal diffusion and diffusion thermo effect are taken to our consideration. The non-linear partial differential equations which govern this problem are simplified by making the assumptions of long wave length approximation. The analytical formula of the velocity, temperature and concentration have been obtained. In addition, it has been illustrated graphically for significant various parameters such as, magnetic parameter, permeability parameter, and thermal parameters

Contribution of Lexico-Semantic Processes to Verbal Short-Term Memory Tasks: A Pet Activation Study

peer reviewedRecent studies have demonstrated the intervention of long-term memory processes in verbal STM tasks and several cognitive models have been proposed to explain these effects. A PET study was performed in order to determine whether supplementary cerebral areas are involved when subjects have to execute short-term memory tasks for items having representations in long-term memory (in comparison to items without such representations: words vs non-words). Results indicate that verbal STM for words specifically involves the left middle temporal gyrus (BA 21) and temporo-parietal junction (BA 39). These areas can be associated with lexical and semantic processes. These results are in agreement with cognitive models that postulate the simultaneous influence of lexical and semantic long-term representations on verbal STM processes and/or a lexico-semantic buffer

A Personalized Intervention to Increase Environmental Health Literacy and Readiness to Change in a Northern Nevada Population: Effects of Environmental Chemical Exposure Report-Back.

BACKGROUND: Interventions are needed to help people reduce exposure to harmful chemicals from everyday products and lifestyle habits. Report-back of individual exposures is a potential pathway to increasing environmental health literacy (EHL) and readiness to reduce exposures. OBJECTIVES: Our objective was to determine if report-back of endocrine-disrupting chemicals (EDCs) can reduce EDC exposure, increase EHL, and increase readiness to change (i.e., to implement EDC exposure-reduction behaviors). METHODS: Participants in the Healthy Nevada Project completed EHL and readiness-to-change surveys before (n = 424) and after (n = 174) a report-back intervention. Participants used mail-in kits to measure urinary biomarkers of EDCs. The report-back of results included urinary levels, information about health effects, sources of exposure, and personalized recommendations to reduce exposure. RESULTS: EHL was generally very high at baseline, especially for questions related to the general pollution. For questions related to chemical exposures, responses varied across several demographics. Statistically reliable improvements in EHL responses were seen after report-back. For readiness to change, 72% were already or planning to change their behaviors. Post-intervention, women increased their readiness (p = 0.053), while men decreased (p = 0.007). When asked what challenges they faced in reducing exposure, 79% cited not knowing what to do. This dropped to 35% after report-back. Participants with higher propylparaben were younger (p = 0.03) and women and participants who rated themselves in better health had higher levels of some phthalates (p = 0.02-0.003 and p = 0.001-0.003, respectively). After report-back, monobutyl phthalate decreased among the 48 participants who had valid urine tests before and after the intervention (p < 0.001). CONCLUSIONS: The report-back intervention was successful as evidenced by increased EHL behaviors, increased readiness to change among women, and a decrease in monobutyl phthalate. An EHL questionnaire more sensitive to chemical exposures would help differentiate high and low literacy. Future research will focus on understanding why men decreased their readiness to change and how the intervention can be improved for all participants
