Building Migrant Civil Society: Indigenous Mexicans in the US

Mexican migrants in the United States are still widely assumed to be an ethnically homogeneous population. Historically, most Mexican migrants did share many common characteristics, coming primarily from rural communities in the central-western part of the country. Over the last two decades, however, the Mexican migrant population has diversified dramatically, both socially and geographically

Mexican Migrant Civic and Political Participation in the U.S.: The Case of Hometown Associations in Los Angeles and Chicago

Mexican migration to the United States is increasingly debated in the public arena, mainly as a result of its sustained high-density flow and vast distribution nationwide. While this growing population has been negatively portrayed in several political and media campaigns, the grassroots organizations forged by these migrants have received less attention. This article examines the increasing civic and political participation of Mexican migrants organized through hometown associations (HTAS), the most prevalent form of voluntary-sector activity among first-generation Mexican migrants in the United States. It focuses on two metropolitan areas, Los Angeles and Chicago, the two major cities with the highest concentrations of Mexican migrants and HTAS in the United States. The article assesses Mexican migrant participation in U.S. politics and civic life through membership in HTAS, showing that these organizations have been a powerful force for social support for their members in the United States, as well as an important mechanism for philanthropic work in Mexico.La migración de mexicanos hacia Estados Unidos se ha convertido en un asunto de creciente debate público, debido principalmente a la alta densidad y permanencia de estos flujos de población y su vasta distribución en Estados Unidos. Mientras que esta población en crecimiento ha sido negativamente representada a través de varias campañas políticas y de medios, las organizaciones comunitarias de base formadas por estos migrantes han recibido menos atención. Este artículo examina la creciente participación cívica y política de los migrantes mexicanos que se organizan en asociaciones de oriundos (HTAs por sus siglas en inglés), que es la forma más común de organización entre los migrantes mexicanos de primera generación en el sector de asociaciones de beneficencia en Estados Unidos. Este artículo se enfoca en dos áreas metropolitanas, Los Ángeles y Chicago, las dos ciudades más importantes que tienen las concentraciones más altas de migrantes mexicanos y asociaciones de oriundos en Estados Unidos. El artículo evalúa la participación de los migrantes mexicanos en la vida política y cívica estadunidense a través de su membresía en asociaciones de oriundos, y revela que estas organizaciones han sido tanto una poderosa fuerza de apoyo social para sus miembros en Estados Unidos como un mecanismo importante de trabajo filantrópico en México

The secretome of bone marrow mesenchymal stem cells-conditioned media varies with time and drives a distinct effect on mature neurons and glial cells (primary cultures)

Transplantation of bone marrow mesenchymal stem cells (BM-MSCs) has been shown to ameliorate the injured central nervous system (CNS). Although these effects were initially attributed to the putative differentiation of MSCs towards the neural lineage, it is now known that most of them are mediated by the secretome. Up to now most in vitro reports have dealt with the effects of the secretome on neural stem cells and their differentiation. Consequently, there is a lack of information regarding the role of the secretome on the viability and survival of pre-existent matured differentiated cell populations. Moreover, it is also not known how the time points of conditioned media (CM) collection affect such parameters. In the present study, primary cultures of hippocampal neurons and glial cells were incubated with CM obtained from MSCs. To determine how the temporal profiles of CM collection impact on post-natal neurons and glial cells, we collected MSCs CM at 24, 48, 72 and 96 h of conditioning. MTS test revealed that for the hippocampal cultures the incubation with CM increased cell viability for all time points, with significant increases in the percentage of neurons in culture incubated with CM 24 h. For glial cells only the later time point of CM collection (96 h) increased cell viability. Fluorescence microscopy observations also revealed that CM 48 h and 72 h increased astrocytes percentages, while CM 24 h decreased microglial cell and oligodendrocytes values. These results revealed that post-natal neuronal and glial cells respond differently to MSCs CM; moreover, there are specific temporal variations in the composition of the CM of MSCs collected at different time points that trigger different effects on mature neurons and the distinct glial cell populations (astrocytes, oligodendrocytes and microglial cells).Fundação Calouste de Gulbenkia

Exploring perceptions of alcohol consumption in unlicensed public places among individuals aged 40 and over: A qualitative study across socioeconomically diverse neighbourhoods in Madrid, Spain

Alcohol consumption in unlicensed public places has become a topic of intense debate in Spain due to its negative impact on health and social outcomes, and the inefficiency of current alcohol policies. This research aimed to explore the perceptions of individuals aged 40 and over regarding alcohol consumption in unlicensed public places in socioeconomically diverse neighbourhoods in Madrid. 37 semi-structured interviews and 29 focus groups were conducted in three neighbourhoods with different socioeconomic statuses. The analysis drew on Corbin and Strauss's grounded theory coding strategies. The findings of the study showed that people aged 40 and over problematised alcohol consumption in unlicensed public places, such as parks and squares. The problematisation followed a two-step process. Initially, non-compliance with current restrictions on alcohol sales during the night-time in convenience stores, including the sale of alcohol to minors, was identified as an issue. This, in turn, led to alcohol consumption in unlicensed public places, which was associated with negative outcomes such as alcohol-related litter, noise nuisance, and violence. These consequences were disproportionally perceived in the least affluent neighbourhood. To address the disproportionate impact of alcohol-related behaviours in the least affluent neighbourhoods, reinforcing existing alcohol sales policies is warranted. This may reduce alcohol consumption in unlicensed public places and its related negative outcomes

Qualitative examination of the perceived effects of a comprehensive smoke-free law according to neighborhood socioeconomic status in a large

Smoke-free legislations aim to protect non-smokers from second-hand smoke (SHS) exposure and improve population health outcomes. The aim of this study was to explore residents' perceptions to understand how people living in distinctive SES neighborhoods are differently affected by comprehensive smoke-free laws in a large city like Madrid, Spain. We conducted a qualitative project with 37 semi-structured interviews and 29 focus group discussions in three different SES neighborhoods within the city of Madrid. Constructivist grounded theory was used to analyze the transcripts. One core category arose in our analyses: Neighborhood inequalities in second-hand smoke (SHS) exposure in outdoor places. The enactment of the comprehensive smoke-free law resulted in unintended consequences that affected neighborhoods differently: relocation of smokers to outdoor setting, SHS exposure, noise disturbance and cigarette butt littering. Changes in the urban environment in the three neighborhoods resulted in the denormalization of smoking in outdoor public places, which was more clearly perceived in the high SES neighborhood. Changes in the built environment in outdoor areas of hospitality venues were reported to actually facilitate smoking. Comprehensive smoke-free laws resulted in denormalization of smoking, which might be effective in reducing SHS exposure. Extending smoking bans to outdoor areas like bus stops and hospitality venues is warranted and should include a public health inequalities perspective
