Immigrants and the Community: Farmworkers with Families

Second in a series based on the research project ?Integrating the Needs of Immigrant Workers and Rural Communities,? which attempts to inform New York communities about the nature and consequences of increasing immigrant settlement.America's hired farm workforce has changed considerably in the last decade. The most apparent change has been its "latinization" during the past two decades. This is largely a consequence of large numbers of Mexicans coming to the United States to work. Although Mexican immigrants work in numerous industries across the American landscape, they are especially important in agriculture. There has been a growing tendency of farmworkers to settle in rural communities together with their immediate family. But how and to what extent does community integration occur? How do foreigners who have little familiarity with American culture become integrated into the community? Answers to these questions have practical importance to farmers interested in retaining their workforce, service providers working to improve farmworker well-being and communities interested in helping the new residents contribute to community development. To help us understand the factors that both promote and limit the integration of immigrants into rural communities, we chose for study five New York agricultural communities in different economic and social contexts that have relied heavily on hired farm labor. Each community has a minority population of some significance and a history of immigrant farmworkers settling there

Usefulness of Bayesian networks in epidemiological studies

Introduction: Bayesian networks are a form of statistical modelling, which has been widely used in fields like clinical decision, systems biology, human immunodeficiency virus (HIV) and influenza research, analyses of complex disease systems, interactions between multiple diseases and, also, in diagnostic diseases. The present study aimed to show the usefulness of Bayesian networks (BNs) in epidemiological studies. Material and Methods: 3,993 subjects (men 1,758, women 2,235) belonging to the public productive sector from the Balearic Islands (Spain), which were active workers, constitute the data set. Results: A BN was built from a dataset composed of twelve relevant features in cardiovascular disease epidemiology. Furthermore, the structure and parameters were learnt with GeNIe 2.0 tool. Taking into account the main topological properties some features were optimized, obtaining a hypothesized scenario where the likelihoods of the different features were updated and the adequate conclusions were established. Conclusions: Bayesian networks allow us to obtain a hypothetical scenario where the probabilities of the different features are updated according to the evidence that is introduced. This fact makes Bayesian networks a very attractive tool.Introducción: Las redes Bayesianas son una forma de modelización estadística, las cuales han sido ampliamente utilizadas en campos como la decisión clínica, biología de sistemas, virus de inmunodeficiencia humana (VIH) e investigación en influenza, análisis de sistemas de enfermedades complejos, interacciones entre múltiples enfermedades y, también, en enfermedades de diagnóstico. Este estudio tiene como objetivo mostrar la utilidad de las redes Bayesianas en estudios epidemiológicos. Material y Métodos: 3,993 individuos (hombres 1,758, mujeres 2,235) pertenecientes al sector productivo público de las Islas Baleares (España), los cuales eran trabajadores activos, constituyen la base de datos. Resultados: Una red Bayesiana se ha obtenido a partir de una base de datos compuesta de doce características relevantes de la epidemiología de la enfermedad cardiovascular. Por otra parte, la estructura y los parámetros se han obtenido con la herramienta Genie 2.0. Teniendo en cuenta las principales propiedades topológicas algunas características fueron optimizadas. Conclusiones: Las redes Bayesianas permiten obtener un escenario hipotético donde las probabilidades de las diferentes características se van actualizando de acuerdo con la evidencia introducida. Este hecho hace de las redes Bayesianas una herramienta muy atractiva, además permite establecer diversas conclusiones

ESTIMATING ENVIRONMENTAL KUZNETS CURVE: THE IMPACT OF ENVIRONMENTAL TAXES AND ENERGY CONSUMPTION IN CO2 EMISSIONS OF OECD COUNTRIES

The objective of the paper is to estimate the relationship between CO2 emissions per capita, GDP per capita, energy consumption and environmental taxes for OECD countries in the period 1994-2014. To perform the above, we estimated a static and dynamic panel data models. The results show that the Environmental Kuznets Curve is verified for OECD countries, and environmental taxes have a negative impact on CO2 emissions (static model). On the other hand, the consumption of energy from fossil fuels has a positive impact on CO2 emissions. We conclude that while the Environmental Kuznets Curve is met, government plays an important role in improving the environment, because environmental taxes have a negative impact on CO2 emissions

Educational applications of a pico-processor design

Knowledge of the internal structure and operating mechanism of microprocessors is a very important part in for engineers in electronics and computer science. This knowledge can be deepened with experiences of processor design, which also meet many aspects linked to other basic skills. However, due to its complexity, the design of commercial processors is not effective from an educational point of view. In this communication we present a VHDL design experience of a very simple processor that shows multiple learning posed to the student

Prognostic Value of Microvascular Density in Dukes A and B (T1–T4, N0, M0) Colorectal Carcinomas

Background. Aproximatelly 30% of patients operated on for colorectal cancer (CRC), with an expectedly favourable prognosis (Dukes A-B/T1–T4, N0, M0) suffer recurrence and/or die. Method. In order to determine if tumor microvascular density (MVD) is a prognostic factor in CRC, samples from tumors of 104 Dukes A-B CRC patients were retrospectively studied. Immunohistochemistry was performed for anti-CD34 antibody to visualize tumor vascularisation. MVD was expressed as the total number of vessels and as the percentage of microvascular area. We calculated MVD with a morphometry program and performed descriptive, bivariate, and survival statistics. Results. The mean number of vessels was 37.37/200x field, and the mean vascular area was the 3.972%. 30% of the patients with < 37 vessels/field, and 21% of the patients with > 37 vessels/field, experienced recurrence/death. The 35% of patients with < 4% of vascular area died following recurrence, compared with 14% of patients with ≥4% of vascular area. These differences in % of vascular area were statistically significant. Conclusion. MVD expressed as the total number of vessels had no a statistically significant influence on the evolution of CRC. However, neoplasias with a greater % of vascular were associated to a better outcome

Demersal and epibenthic communities of sedimentary habitats in the Avilés Canyon System, Cantabrian Sea (NE Atlantic)

The aim of this study was to describe the epibenthic and demersal communities of the Avilés Canyon System (ACS) in relation to the environmental variables that characterize their biotope. ACS (Cantabrian Sea, NE Atlantic) was recently included in the Natura 2000 network as a Site of Community Importance (SCI). Data of faunal biomass derived from 6 surveys carried out using beam trawl and otter trawls in 2009 and 2010 within INDEMARES and ERDEM projects. Data were divided into two groups to obtain information about the two ecological compartments: benthic and demersal. The total number of species used in this analysis ascended to 116 in the case of benthic organisms and 110 in the case of demersal. Hierarchical clustering analysis was applied to obtain groups of samples similar in terms of species composition for the two ecological components. Depth was the main discriminating factor for grouping hauls, showing high consistency of bathymetric range independently from the compartment examined. Six groups were identified by depth as follows: medium shelf (∼100–200 m), external shelf (∼150–300m), shelf break (∼300–400 m), upper-slope (∼500–700 m), upper middle-slope (∼700–1100 m), and lower-middle-slope (1200–1500 m). SIMPER analysis on biomass values was performed to determine the structure of the faunal assemblages observed for each group in both compartments. Using biomass values for the analysis allowed for the exploration of groups playing important roles in ecosystem functioning and energy fluxes taking place on the sedimentary bottom of this SCI. Finally, CCA analysis revealed that the main environmental drivers were depth, broad scale bathymetric position index (BPI), near-bottom salinity, sedimentary type, and dynamics related variables (Q50 phy and So). This study gives an inventory of the soft bottom assemblages along a very wide depth range (100–1500 m) inside a SCI, linking both epibenthic and demersal communities with the biotope preferences. This study contributes to fundamental knowledge on soft-bottom communities as a pre-requisite, necessary for the next steps in terms of management framework in the SCI

Lamb–Shaffer syndrome: 20 Spanish patients and literature review expands the view of neurodevelopmental disorders caused by SOX5 haploinsufficiency

Lamb–Shaffer Syndrome (LSS; OMIM #616803; ORPHA #313892; ORPHA #313884) is an infrequent genetic disorder that affects multiple aspects of human development especially those related to the development of the nervous system. LSS is caused by variants in the SOX5 gene. At the molecular level, SOX5 gene encodes for a transcription factor containing a High Mobility Group (HMG) DNA-Binding domain with relevant functions in brain development in different vertebrate species. Clinical features of Lamb–Shaffer syndrome may include intellectual disability, delayed speech and language development, attention deficits, hyperactivity, autism spectrum disorder, visual problems and seizures. Additionally, patients with the syndrome may present distinct facial dimorphism such as a wide mouth with full lips, small chin, broad nasal bridge, and deep-set eyes. Other physical features that have been reported in some patients include short stature, scoliosis, and joint hypermobility. Here, we report the clinical and molecular characterization of a Spanish LSS cohort of new 20 patients and review all the patients published so far which amount for 111 patients. The most frequent features included developmental delay, intellectual disability, visual problems, poor speech development and facial dysmorphic features. Strikingly, pain insensitivity and hypermetropia seems to be more frequent than previously reported, based on the frequency seen in the Spanish cohort. Eighty-three variants have been reported so far, single nucleotide variants (SNV) and copy number variants represent 47% and 53%, respectively, from the total of variants reported. Similarly to previous reports, the majority of the SNVs variants of the novel patients reported herein fall in the HMG domain of the protein. However, new variants, affecting other functional domains, were also detected. In conclusion, LLS is a rare genetic disorder mostly characterized by a wide range of developmental and neurological symptoms. Early diagnosis would allow to start of care programs, clinical follow up, prospective studies and appropriate genetic counseling, to promote clinical and social improvement to have profound lifelong benefits for patients and their families. Further research is needed to better understand the underlying mechanisms of the syndrome related to SOX5 haploinsufficiency.European Regional Development Fund;Instituto de Salud Carlos III, Grant/AwardNumbers: PI20/01053, PMP22/00049,PMP21/0006

A multiproxy study distinguishes environmental change from diagenetic alteration in the recent sedimentary record of the inner Cadiz Bay (SW Spain)

In this study, we reconstruct the recent environmental evolution of the inner Cadiz Bay using sedimentary records reaching back as far as AD 1700. We report lithological descriptions of the sediments and extensive mineralogical and geochemical analyses. An extraction technique that identifies different Fe phases provides an assessment of diagenetic alteration, which allows an estimation of the original organic matter inputs to the inner Cadiz Bay. Downcore variations in Corg/N ratios, δ13Corg and δ15N are related to changes in organic matter sources and the trophic state of the water column. The downcore records of selected trace metals (e.g. Pb, Zn and Cu) are interpreted to reflect changes in heavy metal pollution in the bay, while records of other elements (e.g. Mn and P) are likely overprinted by diagenetic alteration. Major environmental shifts took place during the 20th century, when the population around Cadiz Bay increased exponentially. Increases in sediment accumulation rates, organic matter inputs and heavy metal contents, in parallel with increases in δ13Corg and δ15N over this period, are interpreted as direct effects of the increasing anthropogenic influence in the area. The results of this study suggest that multiproxy approaches and detailed consideration of diagenetic overprinting are required to reconstruct past environmental conditions from coastal sediments
