    This paper emphasizes the pedagogical contributions that drove the political awareness and action of Black and Brown youth in Chicago from 1966-1975. The critical education of the Communiversity on the Southside and the Chicago Young Lords Organization (ChYLO) on the Northside addressed deficiencies in educational institutions and aided urban youth in combating the post-industrial, socio-political, and economic challenges of Chicago communities. Through a critical analysis of interview and archival data of ChYLO and Communiversity, we highlight their significant contributions to the field of education. In this article, we frame these formations as the work of critical pedagogy. Our analysis of these youth/student organizations uncovers frameworks that contribute to the work of educators and youth via: 1) examination of educational topics rooted in community concerns, 2) the study of texts that promote critical understandings and analysis of unjust structures and systems at local, national and global levels, and 3) pedagogical practices that account and adjust for the living and learning conditions of poor Black and Brown communities

    Methylated DNA changes associated with the initiation and maintenance of Vitis vinifera in vitro shoot and callus cultures: A possible mechanism for age-related changes

    Tissue culture technologies are an important aspect of the genetic modification of grapevine (Vitis vinifera). The molecular basis of this phenomenon is not well understood, however, the extent of DNA methylation is recognised as a factor in the control of gene expression. This study explores the possibility that DNA methylation may have a role in grapevine culture responses. DNA methylation profiles were constructed for Vitis vinifera, cv. Sultanina, during plantlet micropropagation, callus induction and proliferation. Methylation of genomic DNA and ribosomal RNA genes (rDNA) was found in glasshouse-grown plants, micropropagated plantlets and callus cultures. An analysis of rDNA showed that glasshouse-grown plants had 74.6% of the recognition sequences for Hpa II methylated at the internal cytosine position CmCGG, whereas 7.7% of the recognition sequences appeared to be methylated at the external cytosine (mCmCGG). The rDNA profiles of micropropagated subcultures S0 (initial subcultures) and S4 (fourth subcultures), representing one year of in vitro growth, showed that the percentage of recognition sequences containing a methylated external cytosine increased from 7.7% in glasshouse-grown plants to 64.5% for S-0 and 72.5% for the S4 subculture. The implications of these findings for the in vitro manipulation of grapevine used in genetic modifications are discussed

    We Try to Create the World That We Want : Intentional Communities Forging Livable Lives in St. Louis

    Get PDF
    This paper analyzes ethnographic research conducted in five intentional communities in the St. Louis region. Intentional communities have long been formed and entered into by people seeking to create more ideal, more livable lives. Our research focused on the demographic and socioeconomic characteristics of the members of the five communities, the motivations of members for joining, and the benefits and shortcomings they experience. In reporting these findings we summarize common themes that help us to better understand why people join intentional communities, how those communities work, and the values and goals that underpin conceptions of quality of life there. We also draw from our data a set of recommendations related to policy obstacles and opportunities that are present in municipalities like St. Louis that facilitate or obstruct the formation of intentional communities and their endeavors to create more livable lives

    Unravelling Soil Fungal Communities from Different Mediterranean Land-Use Backgrounds

    Fungi strongly influence ecosystem structure and functioning, playing a key role in many ecological services as decomposers, plant mutualists and pathogens. The Mediterranean area is a biodiversity hotspot that is increasingly threatened by intense land use. Therefore, to achieve a balance between conservation and human development, a better understanding of the impact of land use on the underlying fungal communities is needed.We used parallel pyrosequencing of the nuclear ribosomal ITS regions to characterize the fungal communities in five soils subjected to different anthropogenic impact in a typical Mediterranean landscape: a natural cork-oak forest, a pasture, a managed meadow, and two vineyards. Marked differences in the distribution of taxon assemblages among the different sites and communities were found. Data analyses consistently indicated a sharp distinction of the fungal community of the cork oak forest soil from those described in the other soils. Each soil showed features of the fungal assemblages retrieved which can be easily related to the above-ground settings: ectomycorrhizal phylotypes were numerous in natural sites covered by trees, but were nearly completely missing from the anthropogenic and grass-covered sites; similarly, coprophilous fungi were common in grazed sites.Data suggest that investigation on the below-ground fungal community may provide useful elements on the above-ground features such as vegetation coverage and agronomic procedures, allowing to assess the cost of anthropogenic land use to hidden diversity in soil. Datasets provided in this study may contribute to future searches for fungal bio-indicators as biodiversity markers of a specific site or a land-use degree

Neuroimaging has informed our understanding of the neurobiology of anxiety disorders, but research has been limited by small sample sizes and low statistical power, as well as heterogenous imaging methodology. The ENIGMA-Anxiety Working Group has brought together researchers from around the world, in a harmonized and coordinated effort to address these challenges and generate more robust and reproducible findings. This paper elaborates on the concepts and methods informing the work of the working group to date, and describes the initial approach of the four subgroups studying generalized anxiety disorder, panic disorder, social anxiety disorder, and specific phobia. At present, the ENIGMA-Anxiety database contains information about more than 100 unique samples, from 16 countries and 59 institutes. Future directions include examining additional imaging modalities, integrating imaging and genetic data, and collaborating with other ENIGMA working groups. The ENIGMA consortium creates synergy at the intersection of global mental health and clinical neuroscience, and the ENIGMA-Anxiety Working Group extends the promise of this approach to neuroimaging research on anxiety disorders
