    Gender, Networks and Mexico-U.S. Migration

    In this paper, we examine whether the causes and patterns of Mexican rural female migration differ significantly from rural male migration. A number of hypotheses are discussed to explain why female migration may differ from male migration, with a particular emphasis on the role of migrant networks. Using data from a national survey of rural Mexican households in the ejido sector, significant differences between the determinants of male and female migration are found. While evidence suggests that networks play an important role in female migration, we find that, contrary to case study evidence, female networks are not more influential than male networks in female migration. In fact, female and male networks are found to be substitutes, suggesting they serve similar functions in female migration. Although female migrant networks do not play a special role in the female migration decision, the destination of female migrants is strongly influenced by the location of female network migrants.migration, networks, gender, Mexico, Labor and Human Capital,

    Updating the (Supermassive Black Hole Mass) - (Spiral Arm Pitch Angle) Relation: A Strong Correlation for Galaxies with Pseudobulges

    We have conducted an image analysis of the (current) full sample of 44 spiral galaxies with directly measured supermassive black hole (SMBH) masses, MBHM_{\rm BH}, to determine each galaxy's logarithmic spiral arm pitch angle, ϕ\phi. For predicting black hole masses, we have derived the relation: log(MBH/M)=(7.01±0.07)(0.171±0.017)[ϕ15deg]\log({M_{\rm BH}/{\rm M_{\odot}}}) = (7.01\pm0.07) - (0.171\pm0.017)[|\phi|-15\deg]. The total root mean square scatter associated with this relation is 0.43 dex in the logMBH\log{M_{\rm BH}} direction, with an intrinsic scatter of 0.33±0.080.33\pm0.08 dex. The MBHM_{\rm BH}-ϕ\phi relation is therefore at least as accurate at predicting SMBH masses in spiral galaxies as the other known relations. By definition, the existence of an MBHM_{\rm BH}-ϕ\phi relation demands that the SMBH mass must correlate with the galaxy discs in some manner. Moreover, with the majority of our sample (37 of 44) classified in the literature as having a pseudobulge morphology, we additionally reveal that the SMBH mass correlates with the large-scale spiral pattern and thus the discs of galaxies hosting pseudobulges. Furthermore, given that the MBHM_{\rm BH}-ϕ\phi relation is capable of estimating black hole masses in bulge-less spiral galaxies, it therefore has great promise for predicting which galaxies may harbour intermediate-mass black holes (IMBHs, MBH<105M_{\rm BH}<10^5 M{\rm M_{\odot}}). Extrapolating from the current relation, we predict that galaxies with ϕ26.7deg|\phi| \geq 26.7\deg should possess IMBHs.Comment: 18 pages, 9 figures, and 4 tables. Accepted July 13.
