Ecology of disjunct cloud forest sugar maple populations (Acer saccharum subsp. skutchii) in North and Central America

The cloud forest sugar maple, Acer saccharum subsp. skutchii, occurs as five disjunct populations, four in Mexico and one in Guatemala. I assessed the current status, distribution, and environmental relations of forests containing these populations, and I compared the species composition of these forests with other temperate and cloud forests in North and Central America. I gave special emphasis to a recently discovered population in Talpa de Allende, Jalisco, Mexico, by assessing its tree richness and generic composition in a continental context. In the five studied cloud forest sugar maple populations, basal area of all trees ¡Ý1 cm DBH varied between 25.7-52.2 m2ha-1, and density ranged from 990-2929 trees per ha. A. saccharum subsp. skutchii represented 7-43% of the total basal area and 1-16% of the tree stems. Bray & Curtis ordination of cloud forest sugar maple populations indicated that most of the variation in relative tree abundance could be explained by soil characteristics and presence of canopy gaps. More cloud forest sugar maples occurred in sites with higher soil moisture (r=0.716). In contrast, a NMS ordination indicated that the majority of the variance in community composition of all temperate and cloud forests analyzed was related to latitude, elevation, and precipitation. Tree species richness of Talpa de Allende and 14 other temperate and cloud forests around the world was significantly different (F=27.53, p=\u3c0.0001). Species richness of forest in Asia and Talpa de Allende did not differ. In addition, generic composition was similar for forests in Asia and Talpa. Based on NMS ordination and Ward&39;s classification, I hypothesize that six forest sites in Jalisco, Tamaulipas, Veracruz, and Hidalgo (Mexico) contain a unique and ancient flora, were connected and shared species before the Pleistocene, and currently function as tree refuges of that ancient flora. Based on the limited distribution of cloud forest sugar maple and its small number of extant populations I propose the inclusion of A. saccharum subsp. skutchii in the IUCN Red List Catalog and as Endangered in the Guatemalan Species Red List. In addition, I propose the creation of a 56,394.9 ha Biosphere Reserve in Talpa de Allende

The association between eating disorders and substance abuse

The goal of this study was to explore the prevalence rates of substance abuse in women that are at risk of eating disorders. At the present time there are no formal treatment programs that address the unique needs of clients with both eating disorders and substance abuse problems. Most agenices will treat these disorders separately

Delivering Information about Retirement Saving among Hispanic Women: Two Facebook Experiments

We conducted two Facebook experiments (the first one during July 21–25, 2016, and the second during April 22–25, 2018) to determine what type of message related to injunctive norms is more effective in getting Hispanic women interested in learning about financial planning for retirement. We also explore how social media tools could be used in future interventions to promote retirement saving among Hispanic women. In both experiments, we found that a message centered on peer influence may be more successful than a message centered on familism in getting Hispanic women interested in learning more about financial planning for retirement. When we disaggregate our data by age and state, we find that click-through rates were higher among Hispanic women between 45 and 55 years old, and the largest number of impressions were among Hispanic women in California and Texas. When we disaggregate our data by device, we find that most study participants were reached through an Android smartphone

Sua taxa de reprovação é, em média, maior que 50%. Nesse contexto, foram instauradas as monitorias da disciplina com os objetivos de: melhorar o seu índice de aprovação; permitir o acesso dos estudantes ao laboratório de informática em horários distintos das aulas para a prática da disciplina; e prover mais um meio para o aluno sanar as dúvidas da disciplina. As monitorias foram ministradas de acordo com o cronograma da disciplina, trabalhando tópicos semanais na ordem das listas de exercícios disponibilizadas pelo professor na plataforma URI Online Judge. Durante o desenvolvimento da monitoria foi preparado e revisado o material de estudo e os conteúdos, foram realizadas atividades de orientação e foram feitos atendimentos nos laboratórios. As monitorias de programação de computadores são fundamentais para apoiar o ensino de uma disciplina com complexidade considerável e com uma alta taxa de reprovaçã

Combining mobile-health (mHealth) and artificial intelligence (AI) methods to avoid suicide attempts: the Smartcrises study protocol

The screening of digital footprint for clinical purposes relies on the capacity of wearable technologies to collect data and extract relevant information’s for patient management. Artificial intelligence (AI) techniques allow processing of real-time observational information and continuously learning from data to build understanding. We designed a system able to get clinical sense from digital footprints based on the smartphone’s native sensors and advanced machine learning and signal processing techniques in order to identify suicide risk. Method/design: The Smartcrisis study is a cross-national comparative study. The study goal is to determine the relationship between suicide risk and changes in sleep quality and disturbed appetite. Outpatients from the Hospital Fundación Jiménez Díaz Psychiatry Department (Madrid, Spain) and the University Hospital of Nimes (France) will be proposed to participate to the study. Two smartphone applications and a wearable armband will be used to capture the data. In the intervention group, a smartphone application (MEmind) will allow for the ecological momentary assessment (EMA) data capture related with sleep, appetite and suicide ideations. Discussion: Some concerns regarding data security might be raised. Our system complies with the highest level of security regarding patients’ data. Several important ethical considerations related to EMA method must also be considered. EMA methods entails a non-negligible time commitment on behalf of the participants. EMA rely on daily, or sometimes more frequent, Smartphone notifications. Furthermore, recording participants’ daily experiences in a continuous manner is an integral part of EMA. This approach may be significantly more than asking a participant to complete a retrospective questionnaire but also more accurate in terms of symptoms monitoring. Overall, we believe that Smartcrises could participate to a paradigm shift from the traditional identification of risks factors to personalized prevention strategies tailored to characteristics for each patientThis study was partly funded by Fundación Jiménez Díaz Hospital, Instituto de Salud Carlos III (PI16/01852), Delegación del Gobierno para el Plan Nacional de Drogas (20151073), American Foundation for Suicide Prevention (AFSP) (LSRG-1-005-16), the Madrid Regional Government (B2017/BMD-3740 AGES-CM 2CM; Y2018/TCS-4705 PRACTICO-CM) and Structural Funds of the European Union.

The importance of games in e – Learning.

Along last decades it has been developed didactic strategies. They have been helped with games’ computer by teaching- learning process. They have been diffused trough of TICs on Line with many educate viewpoints. In this case it has helped in social-cultural theories that have proposed starting and promoting of educative competences, trough e-Learning tools, which there have incorporate Social networks. Do a balance of e-Learning’s game be able to develop in open access, founded specially in 2015 years ago. Documental review with transversal cut which rescues pedagogical view points and research finding implies ludic activities and his relationship games-competences together. Proposing to apply social historic cultural theory in Learning’s game with competences activation trough Web 2.0.The game, imagination, fantasy, simulating, as part or entertainment, are unique aspects in humans learning throughout the lifeli ne. Constitute a part of the personality, start from the common sense knowledge and can be an engine of development to reach metacognition. Today, with the advancement of information and communication technologies, ICT and learning technology and knowledge, CT scans, there is a huge amount of games creations in differe nt platforms which accumulate thousands of them and new applications that allow people to transform themselves while they go away from their reality. The games are diverse, but in this article we are interested in talking about those which were made with a didacti

Averaged Nystr\"om interpolants for the solution of Fredholm integral equations of the second kind

Fredholm integral equations of the second kind that are defined on a finite or infinite interval arise in many applications. This paper discusses Nystr\"om methods based on Gauss quadrature rules for the solution of such integral equations. It is important to be able to estimate the error in the computed solution, because this allows the choice of an appropriate number of nodes in the Gauss quadrature rule used. This paper explores the application of averaged and weighted averaged Gauss quadrature rules for this purpose. New stability properties of the quadrature rules used are shown.Comment: 26 pages, 2 figure
