Indigenous female entrepeneurship: a qualitative studies in the context of Bolivia

Indigenous entrepreneurship and the gender approach to entrepreneurship are areas that have grown in interest in the entrepreneurship literature in recent years. This paper combines both research streams with the aim of analysing the social and individual factors affecting indigenous quechua female entrepreneurs of Bolivia. Based on the analysis of qualitative data from forty-two face-to-face interviews to indigenous entreprenerurs (female and male), the specific characteristics of these entrepreneurs, the barriers and the facilitators of entrepreneurial activities by women, as well as the role of social capital were extracted. The existence of a sexist and patriarchal culture has been found. However, regarding production, family becomes the production unit; the woman and the man have specific and complementary roles. In addition, there is growing individualism that results in a loss of indigenous values

Acceleration of an unpolarized proton along a uniform magnetic field: Casimir momentum of leptons

Producción CientíficaIt has been recently shown that a chiral molecule accelerates linearly along a spatially uniform magnetic field, as a result of the parity-time symmetry breaking induced in its QED self-interaction. In this work we extend that result to fundamental particles which present EW self-interaction, in which case parity is violated by the EW interaction itself. In particular, we demonstrate that, in a spatially uniform and adiabatically timevarying magnetic field, an unpolarized proton coupled to the leptonic vacuum acquires a kinetic momentum antiparallel to the magnetic field, whereas virtual leptons gain an equivalent Casimir momentum in the opposite direction. That momentum is proportional to the magnetic field and to the square of Fermi’s constant. We prove that the kinetic energy of the proton is a magnetic energy which constitutes a Doppler-shift correction to its EW self-energy

Novel Ruthenium-Silver PTA-Based Polymers and Their Behavior in Water

New coordination polymers based on two metal-containing moieties Ru–Ag are synthesized: Na[RuCpX(PTA)-μ-(PTA)-1κP:2κ2N-AgX2]∞ (X = Cl (1), Br (2), I (3)). Characterization is performed by NMR, UV-visible and FT-IR spectroscopy, optical-electron microscopy, and elemental analyses (C, H, N, S). Light scattering is employed to characterize the colloidal particles growth by polymer self-assembling. These structures are stable over a broad range of pH and exhibit thermally-driven swelling, thus resembling a typical thermosensitive hydrogel
