Genomic transformation and social organization during the Copper Age-Bronze Age transition in southern Iberia.

The emerging Bronze Age (BA) of southeastern Iberia saw marked social changes. Late Copper Age (CA) settlements were abandoned in favor of hilltop sites, and collective graves were largely replaced by single or double burials with often distinctive grave goods indirectly reflecting a hierarchical social organization, as exemplified by the BA El Argar group. We explored this transition from a genomic viewpoint by tripling the amount of data available for this period. Concomitant with the rise of El Argar starting ~2200 cal BCE, we observe a complete turnover of Y-chromosome lineages along with the arrival of steppe-related ancestry. This pattern is consistent with a founder effect in male lineages, supported by our finding that males shared more relatives at sites than females. However, simple two-source models do not find support in some El Argar groups, suggesting additional genetic contributions from the Mediterranean that could predate the BA.

El criterio del azar vs. la ponderación en la asignación de recursos sanitarios escasos ante emergencias sanitarias / Chance vs. weighting criteria in allocating scarce health resources to health emergencies / O critério da casualidade versus a ponderação na atribuição de recursos sanitários escassos diante de emergências sanitárias

Resumen Cuando suceden eventos como una pandemia, en donde hay que velar por la salud de toda una población, el enfoque se centra en la salud pública. Aunque existen varios criterios con los cuales se pueden tomar estas decisiones, conviene profundizar más sobre la ponderación que va más allá de la simple consideración de factores a primera vista visibles. Se propone la ponderación como mecanismo en lugar del azar ya que, dada la unidad sustancial de la persona y su intrínseca dignidad, su destino no puede quedar sujeto a nada menos que la aplicación del juicio inteligible propio de la razón humana.

Abstract When events such as a pandemic occur, and the entire population's health must be ensured, the focus is on public health. Despite several criteria for decision-making, it is advisable to delve into the weighting beyond the mere consideration of plainly visible factors. We propose weighting as a mechanism instead of chance since, given the person's substantial unity and intrinsic dignity, their destiny cannot be subject to anything less than the exercise of intelligible judgment inherent to human reason.

Resumo Quando ocorrem eventos como uma pandemia, em que se é necessário garantir a saúde de toda uma população, o foco centra-se na saúde pública. Ainda que existam vários critérios com os quais se podem tomar essas decisões, convém aprofundar mais sobre a ponderação que vai além da simples consideração de fatores à primeira vista visíveis. Propõe-se a ponderação como mecanismo em vez da casualidade já que, dada a unidade substancial da pessoa e sua intrínseca dignidade, seu destino não pode ficar sujeito a nada menos que a aplicação do julgamento inteligível próprio da razão humana.

The European tomato market. An approach by export competitiveness maps.

Most empirical studies examining the export competitiveness of a country in a target market are undertaken by focusing on supply, only analysing the group of competing countries. In addition, if the target market to be analysed is extensive, like the European Union, it is generally analysed as a whole. This study presents an evaluation of the tomato export competitiveness, from a differentiated demand perspective, analysing its main customers markets in the context of European Union. The methodological framework is implemented through Constant Market Share to analyze variations in exports, allowing the portion attributable to competitiveness and segregation into general or specific competitiveness to be quantified. The Constant Market Share was adapted to focus on the differentiated demand so as to observe the influence of the worldwide crisis (2007/08) on the European tomato market. This study allows the analysis of profile changes into the competitor exporting economies. As a contribution to the methodology, this study presents a new graphical way of representing the results of Constant Market Share methodology by means of export competitiveness maps in the European tomato market for the group for each main competitor in each European client market. According to our results, Spain and Belgium are candidate countries to be competitive in the main European markets.

Environmental and socioeconomic risk factors associated with visceral and cutaneous leishmaniasis: a systematic review.

We performed a systematic review of the literature published since 1900 about leishmaniasis a neglected vector-borne disease, focused on environmental and social risk factors for visceral (VL) and cutaneous leishmaniasis (CL) to better understand their impact on the incidence of disease. The search terms were "leishmaniasis" AND "risk factors" using Google Scholar, PudMed, and Scielo. We reviewed 177 articles, 95 studies for VL, 75 for CL, and 7 on both forms. We identified 14 categories of risk factors which were divided into three groups: socioeconomic (7), environmental (5), and climate (2) variables. Socioeconomic factors were also associated with disease incidence in vulnerable human populations of arid and tropical developing regions. Environmental and climate factors showed significant associations with the incidence of VL and CL in all the studies that considered them. Proximity to natural vegetation remnants increased disease risk in both the New and Old World while the climate conditions favorable for disease transmission differed among regions. We propose a common conceptual framework for both clinical forms that highlights networks of interaction among risk factors. In both clinical forms, the interplay of these factors played a major role in disease incidence. Although there are similarities in environmental and socioeconomic conditions that mediate the transmission cycle of tropical, arid, and Mediterranean regions, the behavior of vector and reservoirs in each region is different. Special attention should be given to the possibility of vector adaptation to urban environments in developing countries where populations with low socioeconomic status are particularly vulnerable to the disease.

Strategic approaches to restoring ecosystems can triple conservation gains and halve costs.

International commitments for ecosystem restoration add up to one-quarter of the world's arable land. Fulfilling them would ease global challenges such as climate change and biodiversity decline but could displace food production and impose financial costs on farmers. Here, we present a restoration prioritization approach capable of revealing these synergies and trade-offs, incorporating ecological and economic efficiencies of scale and modelling specific policy options. Using an actual large-scale restoration target of the Atlantic Forest hotspot, we show that our approach can deliver an eightfold increase in cost-effectiveness for biodiversity conservation compared with a baseline of non-systematic restoration. A compromise solution avoids 26% of the biome's current extinction debt of 2,864 plant and animal species (an increase of 257% compared with the baseline). Moreover, this solution sequesters 1 billion tonnes of CO2-equivalent (a 105% increase) while reducing costs by US$28 billion (a 57% decrease). Seizing similar opportunities elsewhere would offer substantial contributions to some of the greatest challenges for humankind.

Coping Strategies and Social Support in a Mobile Phone Chat App Designed to Support Smoking Cessation: Qualitative Analysis.

BACKGROUND: Smoking is one of the most significant factors contributing to low life expectancy, health inequalities, and illness at the worldwide scale. Smoking cessation attempts benefit from social support. Mobile phones have changed the way we communicate through the use of freely available message-oriented apps. Mobile app-based interventions for smoking cessation programs can provide interactive, supportive, and individually tailored interventions. OBJECTIVE: This study aimed to identify emotions, coping strategies, beliefs, values, and cognitive evaluations of smokers who are in the process of quitting, and to analyze online social support provided through the analysis of messages posted to a chat function integrated into a mobile app. METHODS: In this descriptive qualitative study, informants were smokers who participated in the chat of Tobbstop. The technique to generate information was documentary through messages collected from September 2014 through June 2016, specifically designed to support a smoking cessation intervention. A thematic content analysis of the messages applied 2 conceptual models: the Lazarus and Folkman model to assess participant's experiences and perceptions and the Cutrona model to evaluate online social support. RESULTS: During the study period, 11,788 text messages were posted to the chat by 101 users. The most frequent messages offered information and emotional support, and all the basic emotions were reported in the chat. The 3 most frequent coping strategies identified were physical activity, different types of treatment such as nicotine replacement, and humor. Beliefs about quitting smoking included the inevitability of weight gain and the notion that not using any type of medications is better for smoking cessation. Health and family were the values more frequently described, followed by freedom. A smoke-free environment was perceived as important to successful smoking cessation. The social support group that was developed with the app offered mainly emotional and informational support. CONCLUSIONS: Our analysis suggests that a chat integrated into a mobile app focused on supporting smoking cessation provides a useful tool for smokers who are in the process of quitting, by offering social support and a space to share concerns, information, or strategies.

Efficacy of a smoking prevention programme in Catalan secondary schools: a cluster-randomized controlled trial in Spain.

AIMS: To evaluate the efficacy of a school-based educational programme in reducing the incidence and prevalence of smoking in secondary school students (compulsory secondary education: CSE) in Catalonia (Spain). DESIGN: Cluster-randomized controlled trial. SETTING: Schools in the Tarragona Health Care Region of Spain. PARTICIPANTS: All students enrolled in the first year of CSE during the 2007-08 school year in the 29 participating schools (n = 2245); 1583 students completed the follow-up over the 4-year study period (804 and 779 in the control and intervention groups, respectively). MEASURES: Self-reported questionnaires were administered during the first quarter of the 2007, 2008, 2009 and 2010 school years. A smoker was defined as 'smoking cigarettes daily or occasionally within the past 30 days'. Multi-level logistic regression analysis was conducted to analyse the prevalence and incidence of smoking between the intervention and control groups. INTERVENTION: A school-based educational programme comprising seven modules, each with a different approach to smoking habits. Each module included activities, work-shops and/or class sessions. FINDINGS: The initial prevalence of smokers in the control and intervention groups who completed the follow-up was 3.9% and 4.2%, respectively. At the end of the study, the prevalence of smokers was 24.4% in the control group and 19.9% in the intervention group. The accumulated incidence of new smokers was 230.57/1000 in the control group and 183.65/1000 in the intervention group. The adjusted odds ratio (OR) comparing the intervention group with the control group was 0.75 [95% confidence interval (CI) = 0.49, 1.15] for smoking prevalence, and 0.74 (95% CI = 0.48, 1.14) for smoking incidence. CONCLUSIONS: A school-based educational intervention for secondary school students in Catalonia, Spain was not found to lead to a statistically significant reduction of smoking prevalence and incidence.

Justicia y escasez: el problema bioético de la distribución de recursos para la salud / Justice and scarcity: the bioethical problem of resource allocation for health care

La salud es el resultado de múltiples factores que rodean a individuos y a poblaciones por lo que no debe ser entendida en sentido único. Uno de los factores que determinan el estado de salud de las personas es el económico; así, la pobreza será determinante para la conservación, mejoría o deterioro de la salud. En el texto se discute la importancia de generar estrategias transversales que ataquen las causas paralelas a la pobreza para fomentar la promoción de la salud tanto individual como comunitaria.

Health is the result of multiple factors that surround individuals and populations so it should not be considered in only one way. One of the factors that most determine it is the economical; poverty is crucial for the conservation, improvement or deterioration of health. This text discusses the importance of generating crossing strategies that attack the causes of poverty and so, induce the promotion of health individually and in community.
