An International Service Learning Guide for Occupational Therapy Students and Clinicians
We ourselves feel that what we are doing is just a drop in the ocean. But the ocean would be less because of that missing drop -Mother Teresa
Increased diversity within the U.S. demands the education of occupational therapy clinicians who can deliver culturally responsive care. The number of immigrants to the U.S. is at an all-time high and the African-American and Hispanic populations are expected to double by mid-century (U.S. Census Bureau, 2008). Occupational therapy students and entry-level clinicians have identified the need for more information, resources, and experience with people from different cultures (Murden et aI., 2008). Service learning and cultural immersion were identified as educational methods that may facilitate the development of cultural competence and lead to culturally sensitive care (Bonder, Martin & Miracle, 2002a; Iwama, 2009; O\u27Grady, 2000; Price et aI., 2005).
This scholarly project culminated in a guide, which is intended to provide occupational therapy students and clinicians with the framework necessary to develop and complete an international service learning experience for the promotion of cultural competence. Guided by the Canadian Model of Occupational Performance and Engagement (CMOP-E), the model of service learning, and adult learning theory, this guide addresses the emotional, intellectual, financial, physical, and social elements of service learning to achieve both learner and client goals. The guide is intended for use in planning an international service learning project in a developing country, but may be adapted for use in local or regional areas of the U.S
Determinação do pH de formação do complexo [Fe(o-fen)3]2+
We suggest this research to find the better complexation's pH of [Fe(o-fen)3]2+ complex. The literature says only that this complex is quantitative since pH 2,0 until 9,0. We verify that at pH 9,2 the complex has the largest absorbance, showing that it is the largest pH complexation.We conclude that 9,2 is the ideal pH for the complexation of Fe(lI) with 1, 10-phenantroline, when this complex is free of interferents. Neste trabalho são apresentadas evidências sobre o melhor pH de complexação do complexo [Fe (o-fen)3]2+. A literatura cita que este complexo é quantitativo desde pH=2,0 até 9,0. Verificamos que a pH=9,2 o complexo tem a maior absorbância, demonstrando que este é o pH de maior complexação. Conclui-se que o pH ideal para a comlexação de Fe (II) com o-fenantrolina, quando este complexo encontra-se livre de interferentes, é 9,2
A unified model for holistic power usage in cloud datacenter servers
Cloud datacenters are compute facilities formed by hundreds and thousands of heterogeneous servers requiring significant power requirements to operate effectively. Servers are composed by multiple interacting sub-systems including applications, microelectronic processors, and cooling which reflect their respective power profiles via different parameters. What is presently unknown is how to accurately model the holistic power usage of the entire server when including all these sub-systems together. This becomes increasingly challenging when considering diverse utilization patterns, server hardware characteristics, air and liquid cooling techniques, and importantly quantifying the non-electrical energy cost imposed by cooling operation. Such a challenge arises due to the need for multi-disciplinary expertise required to study server operation holistically. This work provides a unified model for capturing holistic power usage within Cloud datacenter servers. Constructed through controlled laboratory experiments, the model captures the relationship of server power usage between software, hardware, and cooling agnostic of architecture and cooling type (air and liquid). An exciting prospect is the ability to quantify the amount of non-electrical power consumed through cooling, allowing for more realistic and accurate server power profiles. This work represents the first empirically supported analysis and modeling of holistic power usage for Cloud datacenter servers, and bridges a significant gap between computer science and mechanical engineering research. Model validation through experiments demonstrates an average standard error of 3% for server power usage within both air and liquid cooled environments

Forest Drought Response Index (ForDRI): A New Combined Model to Monitor Forest Drought in the Eastern United States
Monitoring drought impacts in forest ecosystems is a complex process because forest ecosystems are composed of different species with heterogeneous structural compositions. Even though forest drought status is a key control on the carbon cycle, very few indices exist to monitor and predict forest drought stress. The Forest Drought Indicator (ForDRI) is a new monitoring tool developed by the National Drought Mitigation Center (NDMC) to identify forest drought stress. ForDRI integrates 12 types of data, including satellite, climate, evaporative demand, ground water, and soil moisture, into a single hybrid index to estimate tree stress. The model uses Principal Component Analysis (PCA) to determine the contribution of each input variable based on its covariance in the historical records (2003–2017). A 15-year time series of 780 ForDRI maps at a weekly interval were produced. The ForDRI values at a 12.5km spatial resolution were compared with normalized weekly Bowen ratio data, a biophysically based indicator of stress, from nine AmeriFlux sites. There were strong and significant correlations between Bowen ratio data and ForDRI at sites that had experienced intense drought. In addition, tree ring annual increment data at eight sites in four eastern U.S. national parks were compared with ForDRI values at the corresponding sites. The correlation between ForDRI and tree ring increments at the selected eight sites during the summer season ranged between 0.46 and 0.75. Generally, the correlation between the ForDRI and normalized Bowen ratio or tree ring increment are reasonably good and indicate the usefulness of the ForDRI model for estimating drought stress and providing decision support on forest drought management

Constructive Hybrid Games
Hybrid games are models which combine discrete, continuous, and adversarial
dynamics. Game logic enables proving (classical) existence of winning
strategies. We introduce constructive differential game logic (CdGL) for hybrid
games, where proofs that a player can win the game correspond to computable
winning strategies. This is the logical foundation for synthesis of correct
control and monitoring code for safety-critical cyber-physical systems. Our
contributions include novel static and dynamic semantics as well as soundness
and consistency.Comment: 60 pages, preprint, under revie

Will Brazilian city dwellers actively engage in urban conservation? A case study with the charismatic neotropical Blue-and-yellow macaw (Ara ararauna)
The Blue-and-yellow macaw (Ara ararauna) is a charismatic and easily recognized species. While they are classified as being of “least concern” in the International Union for Conservation of Nature (IUCN) Red List, their populations are declining. In Brazil, the accelerated destruction of one of its key habitats, the Cerrado biome, is a principal cause of their decreasing abundance. As with other species affected by loss of the Cerrado, active conservation measures are required. While usually rare in urban ecosystems, Ara ararauna occurs and breeds in small numbers in the city of Rondonópolis, a medium-sized city located in Mato Grosso, Central-West Region of Brazil. Blue-and-yellow macaw pairs nest in the tops of dead palm trees, but as the macaws are nest-site limited and suitable dead trees are scarce in urban areas, the installation of artificial nest sites in domestic backyards could help that urban population to thrive. To investigate whether local people would be willing to engage with conservation efforts and in particular to support macaw conservation, we surveyed the attitudes of Rondonópolis residents to measure: (1) citizens’ preferences among the bird species that occur in the city; (2) the average area of their yards, and (3) the willingness of residents to: (a) plant fruit trees to attract macaws to their yards and (b) to install artificial nests in their yards. Larger and more colorful birds (Ara ararauna, the Red-and-green macaw Ara chloropterus and Toco toucan Ramphastos toco) were the bird species most valued across all socio-economic groups, suggesting that the charismatic species would be more likely to be supported by urbanites. Overall, people had good biodiversity knowledge, with respondents being able to identify half of our sample of local bird species, on average, and almost half had seen a nest site. The great majority were willing to plant fruit trees (78%) and provide nest sites (70%) for macaws. This willingness to engage was not affected by socioeconomic differences. These data indicate that a municipal macaw conservation program could be successful in Rondonópolis, and we argue that macaws could be a flagship species which would benefit wider efforts to engage Brazilian urbanites in active engagement with nature
