In Her Husband’s Family: A Newly Wed Woman’s Expectations and Her New Family’s Attitudes in Rural Assam, India

From the introduction: Until recently, living in a joint family system was typical among Hindus and members of other religious groups in India. Living in an extended joint family was also a common practice. However, joint family groups and extended joint family living are now relatively rare, due to India’s economic and social developments over the past four decades or so. Currently, the most common family arrangement is that of the nuclear family, comprised of a father, mother and their children. In rural areas, this nuclear family unit operates within a number of more traditional expectations and arrangements, however. Within a rural Hindu family, for example, a woman’s status varies according to factors such as her age, her marital status, her relationship to different members of her family, her ability to bear children and her status as a mother. A young, newly wed woman may be treated differently by her in-laws than by her own parents; a young widow living in her husband’s family may be treated differently by her new family than she would be were her husband still alive; a daughter-in-law from a poor family may be received differently than she would be received were she from a wealthier family. Similarly, a young unmarried woman living with her natal family may face a degree of hostility from a stepmother that she would not face from her natural mother

Sensory organ like response determines the magnetism of zigzag-edged honeycomb nanoribbons

We present an analytical theory for the magnetic phase diagram for zigzag edge terminated honeycomb nanoribbons described by a Hubbard model with an interaction parameter U . We show that the edge magnetic moment varies as ln U and uncover its dependence on the width W of the ribbon. The physics of this owes its origin to the sensory organ like response of the nanoribbons, demonstrating that considerations beyond the usual Stoner-Landau theory are necessary to understand the magnetism of these systems. A first order magnetic transition from an anti-parallel orientation of the moments on opposite edges to a parallel orientation occurs upon doping with holes or electrons. The critical doping for this transition is shown to depend inversely on the width of the ribbon. Using variational Monte-Carlo calculations, we show that magnetism is robust to fluctuations. Additionally, we show that the magnetic phase diagram is generic to zigzag edge terminated nanostructures such as nanodots. Furthermore, we perform first principles modeling to show how such magnetic transitions can be realized in substituted graphene nanoribbons.Comment: 5 pages, 5 figure

Broad Band Optical Polarimetric Study of IC 1805

We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled and subtracted the foreground dust contribution from the maximum polarization (P_{max}) and colour excess (E_{B-V}). The mean value of the P_max for intracluster medium and the foreground are found to be 5.008 +/-0.005 % and 4.865 +/-0.022 % respectively. Moreover, the mean value of the wavelength of maximum polarization (lambda_{max}) for intracluster medium is 0.541 +/- 0.003 micro m, which is quite similar as the general interstellar medium (ISM). The resulting intracluster dust component is found to have negligible polarization efficiency as compared to interstellar dust. Some of the observed stars in IC 1805 have shown the indication of intrinsic polarization in their measurements.Comment: 8 pages, 7 figures, Accepted for publication in MNRA
