Global Migrations and Imagined Citizenship: Examples From Slavery, Chinese Exclusion, and When Questioning Birthright Citizenship

These theoretical approaches motivate this Essay to ask the following about legal citizenship determinations: (a) what is the global movement in persons that leads to the citizenship question?; and (b) what is the imagined community articulated by the legal determination of citizenship? From these questions, a legal inquiry into national identity and citizenship gains historical, global, and cultural perspectives. The next three sections briefly describe the examples of slavery, Dred Scott, and citizenship; Chinese migration to the U.S., Chinese Exclusion measures, and citizenship; and citizenship as seen from a migration experience of U.S.-pull and Mexico-push. For each of the cases their respective sections, Sections II through IV, present these legal citizenship determinations and then identify relevant global migration and imagined community contexts

Potencial bioquímico de metano de desechos agrícolas como fuente renovable alternativa para la producción de energía eléctrica en Cuba

The present Cuban economic model focuses on renewable sources of energy production, according to sustainable development strategies for 2030. However, the strategies do not consider biogas (or methane) due to, among other reasons, a lack of knowledge of its actual potential. Following the methodology of the batch anaerobic digestion process, the study shows the biomethane potential contained in the most critical agricultural solid wastesgenerated in Cuba, i.e., rice straw, cane straw, corn straw, bean straw, banana straw (leaves), coffee husk, and parchment coffee. Biochemical Methane Potential (BMP) was assayed by lab-scale (585 ml) batch reactors, using the pig manure anaerobic sludge as inoculum under mesophilic conditions (35 ± 2 °C). Physicochemical parameters (total volatile solids, pH, alkalinity, volatile fatty acid concentration, and alkalinity ratio) were determined for processstability, quantifying the biogas production daily. Subsequently, the BMP was calculated for all substrates. The results showed that corn straw (0.42 l CH4 per gram of volatile solids) contained the highest biomethane potential. Stability on all systems was obtained, demonstrating the viability of the inoculum used to start digesters that treat this waste.The total potential methane obtained was 1258 106 m3/year, which is enough to generate 3,750 GWh of power per year—equivalent to 18 % of the total annual electricity generation in the country.El modelo económico cubano actual se centra en las fuentes renovables de producción de energía, de acuerdo con las estrategias de desarrollo sostenible para 2030, pero dichas estrategias no consideran el biogás, debido, entre otras causas, al poco conocimiento de su potencial real. Siguiendo la metodología del proceso de digestión anaeróbica en lote, el estudio muestra el potencial del biometano contenido en los residuos sólidos agrícolas másimportantes que se generan en Cuba, es decir, paja de arroz, paja de caña, paja de maíz, paja de frijol, paja de plátano (hojas), cáscara y café pergamino. El potencial bioquímico del metano se ensayó mediante reactores discontinuos a escala de laboratorio (585 ml), utilizando como inóculo un lodo anaeróbico de estiércol de cerdo en condicionesmesófilas (35 ± 2 °C). Se determinaron los parámetros fisicoquímicos (sólidos volátiles totales, pH, alcalinidad, concentración de ácidos grasos volátiles) para evaluar la estabilidad del proceso, y se cuantificó la producción diaria de biogás; posteriormente, se calculó el potencial bioquímico del metano para todos los sustratos. Los resultados mostraron que la paja de maíz (0,42 l CH4 por gramo de sólidos volátiles) contenía el mayor potencial de biometano. Se obtuvo estabilidad en todos los sistemas y se demostró la viabilidad del inóculo utilizado para poner en marcha los digestores que tratan estos residuos. El potencial total de metano obtenido fue de 1258 106 m3/año, lo suficiente para generar 3750 GWh de energía por año, equivalente al 18 % de la generación total de electricidad anual del país

Biomass Accumulation and Carbon Storage in Pinus maximinoi, Quercus robur, Quercus rugosa, and Pinus patula from Village- Forests of Chiapas, Mexico

The Frailesca region (Chiapas, Mexico) presents a lack of forest studies and its environmental contribution. This chapter displays a first case study with preliminary research information regarding the identification of main forest trees and rural villages with best potential for biomass production and carbon storage management. Twenty two plots of 500 m2 were selected in 11 villages of the region, in order to identify the main and dominant forest trees species and then to estimate the biomass production and carbon storage in pine (Pinus maximinoi), oak (Quercus robur), holm oak (Quercus rugosa) and Mexican weeping pine (Pinus patula) species. This study shows that the largest accumulation of both biomass and carbon occurred in the pine forests and the lowest in the oak forests. Pine trees showed carbon storage of 516.75 Mg ha−1, followed by holm oaks, with 297.21 Mg ha−1; the species with the lowest value was oak, with 75.02 Mg ha−1. The forests of the 24 de Febrero villages had the highest potential for carbon storage. Deep studies are being conducted in relation to the aboveground biomass, carbon contents in trees stem, branches and leaves, and the relation to biomass dynamics and carbon stocks and other ecological aspects of village-forests

NeuroBoricuas: a novel approach for incorporating neuroscience education in schools of Puerto Rico

[EN] Puerto Rico is in dire need of transforming its education system to counter the current economic recession and ensure a future with talented Puerto Ricans at the forefront of scientific research and technology development.  Here we present a group of neuroscientists and educators, the NeuroBoricuas, committed to revolutionize the scientific culture of Puerto Rico by incorporating neuroscience research training and inquiry-based activities in public and private schools. We carry out our vision through diverse methods, such as community outreach activities, where we promote neuroscience literacy using diverse learning activities. In parallel, we are designing a neuroscience course and textbook with educators to be implemented in schools. We also established neuroscience laboratories in K-12 schools and trained science teachers to manage such laboratories, using equipment from the company “Backyard Brains”. These laboratory experiences are integrated into the academic curriculum in high schools and the equipment is also available for students interested in designing their independent research projects. Lastly, we are expanding a network of committed scientists who partner with educators to help nurture future neuroscientists early in their academic endeavors. Here, we describe our trajectory and our approach to transform scientific education in Puerto Rico.We thank Dr. Gregory J. Quirk, Dr. Daniel Colon-Ramos and Dr. Mark Miller for their support. We thank Tim Marzullo, from Backyard Brains, for supporting NeuroBoricuas. We also thank Palabreria, Digi-Serv and Puerto Rico 4.0 for their constant support. We thank all the NeuroBoricuas that selflessly work hard for a better Puerto Rico.

Wastewater monitoring of a community COVID-19 outbreak in a Spanish municipality

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) wastewater surveillance has become an increasingly important tool since the initial moments of the coronavirus disease (COVID-19) pandemic, mainly conducted at a large population scale. However, the large-sized sewersheds may not provide suitable information for monitoring localized outbreaks. After the declaration of a community COVID-19 outbreak in two neighborhoods of Castellón (Spain), SARS-CoV-2 RNA levels were monitored in wastewater samples. Moreover, genomic sequencing was performed. Thirty-three samples were collected in 2020, distributed over three points of the sewage network, two of which were close to the areas where the cases were declared. The third point was located at the inlet of the municipal wastewater treatment plant (WWTP). The samples were analyzed by RT-qPCR, using specific N1 and N2 target regions. The sum of confirmed cases, with the date of symptoms onset within the 3 weeks before each sampling day, was calculated. SARS-CoV-2 RNA was detected on most days in the two sampling points at neighborhood level, and the detection became negative when the number of cases with symptoms onset during the last 21 days in the study areas decreased to 0 or 1 case. The genomic sequencing performed for RNA from wastewater and clinical samples showed the same variant. The detection of SARS-CoV-2 and the subsequent non-detection provided the epidemiologists in charge of controlling the outbreak with useful information to confirm its closure, complementing the clinical and epidemiological data. Our findings illustrate the value of wastewater surveillance for localized outbreaks, especially in situations of low incidence of COVID-19 at the broader community level

Oseltamivir-Resistant Pandemic (H1N1) 2009 Virus, Mexico

During May 2009–April 2010, we analyzed 692 samples of pandemic (H1N1) 2009 virus from patients in Mexico. We detected the H275Y substitution of the neuraminidase gene in a specimen from an infant with pandemic (H1N1) 2009 who was treated with oseltamivir. This virus was susceptible to zanamivir and resistant to adamantanes and oseltamivir

Towards precision medicine: defining and characterizing adipose tissue dysfunction to identify early immunometabolic risk in symptom-free adults from the GEMM family study

Interactions between macrophages and adipocytes are early molecular factors influencing adipose tissue (AT) dysfunction, resulting in high leptin, low adiponectin circulating levels and low-grade metaflammation, leading to insulin resistance (IR) with increased cardiovascular risk. We report the characterization of AT dysfunction through measurements of the adiponectin/leptin ratio (ALR), the adipo-insulin resistance index (Adipo-IRi), fasting/postprandial (F/P) immunometabolic phenotyping and direct F/P differential gene expression in AT biopsies obtained from symptom-free adults from the GEMM family study. AT dysfunction was evaluated through associations of the ALR with F/P insulin-glucose axis, lipid-lipoprotein metabolism, and inflammatory markers. A relevant pattern of negative associations between decreased ALR and markers of systemic low-grade metaflammation, HOMA, and postprandial cardiovascular risk hyperinsulinemic, triglyceride and GLP-1 curves was found. We also analysed their plasma non-coding microRNAs and shotgun lipidomics profiles finding trends that may reflect a pattern of adipose tissue dysfunction in the fed and fasted state. Direct gene differential expression data showed initial patterns of AT molecular signatures of key immunometabolic genes involved in AT expansion, angiogenic remodelling and immune cell migration. These data reinforce the central, early role of AT dysfunction at the molecular and systemic level in the pathogenesis of IR and immunometabolic disorders

Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
