Community Perspectives on Access to and Availability of Healthy Food in Rural, Low-Resource, Latino Communities.

IntroductionAttention has focused on the food environment as a result of the growing concern with obesity rates among Latinos in rural areas. Researchers have observed associations between a lack of physical access to affordable produce in areas where supermarkets and grocery stores are limited and poor dietary intake and obesity; these associations are high in rural, low-resource neighborhoods with a high population of Latino residents. We aimed to engage residents of low-resource, Latino-majority neighborhoods in discussions of food access in a rural yet agricultural community setting, which is typically described as a "food desert."MethodsWe used a mixed-methods approach and conducted 3 focus groups (n = 20) and in-depth interviews (n = 59) and surveys (n = 79) with residents of a rural yet agricultural community. We used thematic analysis to explore residents' perceptions of access to healthy foods.ResultsResidents (n = 79; mean age, 41.6 y; 72% female; 79% Latino; 53% Spanish-speaking) reported that dollar and discount stores in this agricultural area provided access to produce; however, produce at retail stores was less affordable than produce at nonretail outlets such as fruit and vegetable stands. Gifts and trades of fruits and vegetables from neighbors and community organizations supplied no-cost or low-cost healthy foods. Residents' suggestions to improve food access centered on lowering the cost of produce in existing retail outlets and seeking out nonretail outlets.ConclusionOur findings contribute to understanding of the food environment in low-resource, rural yet agricultural areas. Although such areas are characterized as "food deserts," residents identified nonretail outlets as a viable source of affordable produce, while indicating that the cost of retail produce was a concern. Innovative policy solutions to increase healthy food consumption must focus on affordability as well as accessibility, and consider alternate, nonretail food outlets in agricultural areas

CARACTERIZACIÓN DE LA FORMACIÓN CIUDADANA PARA EL RECONOCIMIENTO DE LA IDENTIDAD SOCIOCULTURAL LOCAL

El presente artículo tiene como propósito acercar al lector-investigador a que analice y profundice en el tema de la Formación Ciudadana en el contexto actual colombiano a partir de la presente caracterización que desde nuestro entorno laboral, escolar y pedagógico hemos logrado detectar. Según Freire, como el mundo está siendo, la Formación del sujeto está en constante construcción; por tanto, la realidad social no es algo acabado que marcha en un único sentido y si el poder se construye, podemos comprender que la construcción de un mundo diferente, un mundo inclusivo, globalizado pero no mercantilizado ni estandarizado, que no elimine los rasgos particulares, es posible. En esa dirección, el contexto social es creado por la propia praxis a través de la concreción de patrones de conductas colectivas cotidianas; por lo que la identidad es un factor de cohesión que permite estructurar las comunidades desde el sentimiento de pertenencia y la solidaridad recíproca. Las identidades son puntos de inclusión que proporcionan seguridad, empatía, autoestima e intercambio colectivo. Teniendo en cuenta la situación social colombiana por la que casi la mayoría de los niños y niñas sufren a diario, se ubica nuestro problema de investigación dentro del debate político, social y pedagógico del quehacer docente en miras de Formar Ciudadanos desde el reconocimiento de la identidad sociocultural local. En Colombia la educación cívica fue una preocupación muy temprana de nuestra historia, y los estudiantes han debido aprender, desde hace casi 200 años, en buena parte como un catecismo que se memoriza, las reglas de conducta cívica, mientras las prácticas reales en la escuela o la sociedad contradecían esas reglas. Desde ese fin: el de Formar Ciudadanos, el problema de investigación lo formulamos de la siguiente manera: ¿Cuál es la caracterización de la enseñanza y el aprendizaje de la formación ciudadana para el reconocimiento de la identidad sociocultural local en el curso novecientos uno de educación básica secundaria, de las instituciones educativas Carlos Ramón Repizo Cabrera de San Agustín y Jesús María Aguirre Charry de Aipe en el departamento del Huila? Y establecidos tres momentos los puntos de convergencia entre el marco teórico y la información hallada se ha podido caracterizar el problema de investigación en a través de la técnica: “triangulación de la información”. El primer momento, corresponde a la etapa descriptiva de la investigación, en el segundo se hará referencia al aspecto metodológico del análisis y, en un tercer momento se caracteriza desde los hallazgos, cómo está la situación de la formación ciudadana en nuestras instituciones educativas en las que trabajamos y así dar luces de cuáles podrían ser los fines, los contenidos y las estrategias para pensar en una Formación para la ciudadanía desde el reconocimiento de la identidad sociocultural local. This article is intended to bring the reader and researcher to analyze and delve into the topic of Citizenship Education in the current Colombian from this characterization from our workplace, school and teaching have been detected. According to Freire, as the world is, the formation of the subject is under constant construction, so the social reality is not finished marching in one direction and if the power is built, we understand that building a different world, an inclusive world, but not commercialized globalized and standardized, do not delete the particular features, is possible. In this sense, the social context is created by the very practice through the realization of collective daily behavior patterns, so that identity is a cohesive factor for structuring communities from the feeling of belonging and mutual solidarity. Identities are points included that provide security, empathy, self-esteem and collective exchange. Taking into account the social situation in Colombia for almost most of the children suffer every day, lies our problem of research within the political debate, social and pedagogical teaching work in order to train citizens from the recognition of identity sociocultural. In Colombia, civic education was a concern early in our history, and students have had to learn, for almost 200 years, largely as a catechism to be memorized, the rules of civic behavior, while actual practices in school society or contradicted those rules. From this purpose: to train citizens, the research problem formulated as follows: What is the characterization of teaching and learning of citizenship education for the recognition of socio-cultural identity in the course of nine hundred and one education basic secondary educational institutions Repizo Carlos Ramon Cabrera of St. Augustine and Jesus Maria Aguirre of AipeCharry in the department of Huila And set the points of convergence between the theoretical and the information found has been able to characterize the research question three times through the technique: "triangulation of information." The first moment corresponds to the descriptive phase of research, the second will refer to the methodological aspect of the analysis and, in a third stage is characterized from the findings, what is the situation of civic education in our educational institutions in we work and thus shed light on what might be the purpose, content and strategies to think of a training for citizenship since the recognition of cultural identity. &nbsp

Revised fission yeast gene and allele nomenclature guidelines for machine readability

Standardized nomenclature for genes, gene products, and isoforms is crucial to prevent ambiguity and enable clear communication of scientific data, facilitating efficient biocuration and data sharing. Standardized genotype nomenclature, which describes alleles present in a specific strain that differ from those in the wild-type reference strain, is equally essential to maximize research impact and ensure that results linking genotypes to phenotypes are Findable, Accessible, Interoperable, and Reusable (FAIR). In this publication, we extend the fission yeast clade gene nomenclature guidelines to support the curation efforts at PomBase (www.pombase.org), the Schizosaccharomyces pombe Model Organism Database. This update introduces nomenclature guidelines for noncoding RNA genes, following those set forth by the Human Genome Organisation Gene Nomenclature Committee. Additionally, we provide a significant update to the allele and genotype nomenclature guidelines originally published in 1987, to standardize the diverse range of genetic modifications enabled by the fission yeast genetic toolbox. These updated guidelines reflect a community consensus between numerous fission yeast researchers. Adoption of these rules will improve consistency in gene and genotype nomenclature, and facilitate machine-readability and automated entity recognition of fission yeast genes and alleles in publications or datasets. In conclusion, our updated guidelines provide a valuable resource for the fission yeast research community, promoting consistency, clarity, and FAIRness in genetic data sharing and interpretation

Retinoic acid degradation shapes zonal development of vestibular organs and sensitivity to transient linear accelerations

Each vestibular sensory epithelium in the inner ear is divided morphologically and physio- logically into two zones, called the striola and extrastriola in otolith organ maculae, and the central and peripheral zones in semicircular canal cristae. We found that formation of striolar/central zones during embryogenesis requires Cytochrome P450 26b1 (Cyp26b1)- mediated degradation of retinoic acid (RA). In Cyp26b1 conditional knockout mice, formation of striolar/central zones is compromised, such that they resemble extrastriolar/peripheral zones in multiple features. Mutants have deficient vestibular evoked potential (VsEP) responses to jerk stimuli, head tremor and deficits in balance beam tests that are consistent with abnormal vestibular input, but normal vestibulo-ocular reflexes and apparently normal motor performance during swimming. Thus, degradation of RA during embryogenesis is required for formation of highly specialized regions of the vestibular sensory epithelia with specific functions in detecting head motions

High Resolution Esophageal Manometry in Patients with Chagas Disease : A Cross-Sectional Evaluation

Gastrointestinal involvement affects 30-40% of the patients with chronic Chagas disease. Esophageal symptoms appear once the structural damage is established. Little is known about the usefulness of high resolution manometry to early identification of esophageal involvement. We performed a cross-sectional study at the Vall d'Hebron University Hospital (Barcelona, Spain) between May 2011 and April 2012. Consecutive patients diagnosed with Chagas disease in the chronic phase were offered to participate. All patients underwent a structured questionnaire about digestive symptoms, a barium esophagogram (Rezende classification) and an esophageal high resolution manometry (HRM). A control group of patients with heartburn who underwent an esophageal HRM in our hospital was selected. 62 out of 73 patients that were included in the study fulfilled the study protocol. The median age of the Chagas disease group (CG) was 37 (IQR 32-45) years, and 42 (67.7%) patients were female. Twenty-seven (43.5%) patients had esophageal symptoms, heartburn being the most frequent. Esophagogram was abnormal in 5 (8.77%). The esophageal HRM in the CG showed a pathological motility pattern in 14 patients (22.6%). All of them had minor disorders of the peristalsis (13 with ineffective esophageal motility and 1 with fragmented peristalsis). Hypotonic lower esophageal sphincter was found more frequently in the CG than in the control group (21% vs 3.3%; p<0.01). Upper esophageal sphincter was hypertonic in 22 (35.5%) and hypotonic in 1 patient. When comparing specific manometric parameters or patterns in the CG according to the presence of symptoms or esophagogram no statistically significant association were seen, except for distal latency. The esophageal involvement measured by HRM in patients with chronic Chagas disease in our cohort is 22.6%. All the patients with esophageal alterations had minor disorders of the peristalsis. Symptoms and esophagogram results did not correlate with the HRM results. Chagas disease is a parasitic disease mainly transmitted to humans by blood-sucking insects. The disease was endemic in Latin America, but it is now a global disease due to migratory movements. The disease can affect the heart and the digestive system (mainly esophagus and colon). Classically, esophageal assessment in Chagas disease is performed by X-ray and self-reported symptoms. However, they lack accuracy and detect only advanced stage of the disease. Recently, new tools, such as esophageal high resolution manometry, provide more detailed information about the motility disorders of the esophagus. We assessed the esophageal involvement in patients with Chagas disease by means of high resolution manometry and compared the findings with the X-ray and self-reported symptoms. We found a low rate of mild severity motility disorders. We did not find an association between X-ray assessment and symptoms with the high resolution manometry findings. The assessment of esophageal involvement in patients with Chagas disease may benefit from early diagnosis by high resolution manometry, although more research is needed

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Family Businesses and Adaptation: A Dynamic Capabilities Approach

The main objective of this research was to propose a framework centred on the dynamic capabilities approach, and to be applied in the context of family businesses’ adaption to their changing business environment. Data were gathered through interviews with ten FBs operating in Western Australia. Based on the findings, the clusters of activities, sensing, seizing, and transforming emerged as key factors for firms’ adaptation, and were reinforced by firms’ open culture, signature processes, idiosyncratic knowledge, and valuable, rare, inimitable and non-substitutable attributes. Thus, the usefulness of the proposed framework was confirmed. Implications and future research opportunities are presented. © 2018, The Author(s)
