Asset Growth

The last 35 years have seen an increase in the scale, diversification, and distribution of assets between households in Dlonguébougou (DBG). Poor economic statistics added to outward signs suggest nothing has changed in villages like DBG, but a more careful look shows major investment in livestock, wells, shops, solar panels, mobile phones, sewing machines, and motorbikes. Most people say they are better off now, having combined migration earnings, crop returns, and livestock sales over the last 35 years to achieve asset growth. A positive interplay of household size and the ability to take risks and reap higher returns means larger households gain higher returns to reinvest in further domestic growth. Will education of children be the next step in the cycle of investment?

Abstract Alloys with gallium, antimony and zinc, whose elements, metal constituent WEEE (they are specified for mobile phones) are particularly important for developing photoelectron devices, simple reproductive methods of producing p-n structures GaSb, also for production and construction of photo-wave cells in solar panels and they are also processes which develop ceramic semiconductors. In addition, these alloys represent possible substitute for standard lead-tin seam. For the complete definition of the properties of the ternary Ga-Sb-Zn system there were performed many researches of the alloys. The microstructures of the alloys were investigated by usage of SEM with EDS and optic microscopy. By usage of CALPHAD method there was detected the isothermal cross-section at 25ºC. The GaSb has similarities in the properties and behaviour with GaAs, and it is a potential material for the construction of the p-n diode, the photo-wave and thermo-photo-wave cells in solar panels and LCDs. Newly developed materials have been recommended as an adequate replacement for lead and arsenic, which are very dangerous and harmful metals.

Significance Home solar panels are providing electricity to households in sub-Saharan Africa (SSA) that otherwise may not link to grids in the near-to-medium term. Just as households managed to bypass formal financial penetration through the introduction of mobile money and landline telephones by the proliferation of mobile phones, home solar systems are poised to offer affordable electricity as costs drop. Impacts Off-grid solar power will improve the health of households that move away from burning fuels for energy. Growth in electricity could improve economic growth while also providing benefits not captured by GDP. While home solar panels could reduce carbon emissions, large-scale power projects will play a bigger role in overall emissions.

Hybrid Portable Universal Adapter is very efficient and new technology which has capable of taking DC and AC input both and can provide constant DC output. This paper presents renewable energy like Solar panels as DC source and normal AC (230V RMS) source. It has controlled circuit incorporated in it to step down AC voltage without using transformer. This model can give constant DC output of 5v. This circuit has parallel converter circuit which converts AC to DC and DC to DC as well. This adapter can be carried easily and we can use it to charge our mobile phones or any power bank

In the present study we link self-report-data on personality to behavior recorded on the mobile phone. This new approach from Psychoinformatics collects data from humans in everyday life. It demonstrates the fruitful collaboration between psychology and computer science, combining Big Data with psychological variables. Given the large number of variables, which can be tracked on a smartphone, the present study focuses on the traditional features of mobile phones – namely incoming and outgoing calls and SMS. We observed N = 49 participants with respect to the telephone/SMS usage via our custom developed mobile phone app for 5 weeks. Extraversion was positively associated with nearly all related telephone call variables. In particular, Extraverts directly reach out to their social network via voice calls.

Convenience Sampling

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.
