Educating the whole child for the whole world
At the dawn of the twenty-first century, we are living in a global era, yet schooling systems remain generally reactive and slow to adapt to shifting economic, technological, demographic, and cultural terrains. There is a growing urgency to create, evaluate, and expand new models of education that are better synchronized with the realities of today's globally linked economies and societies.Educating the Whole Child for the Whole World examines one such model: the ethos and practices of the Ross Schools and their incubation, promotion, and launching of new ideas and practices into public education. Over the last two decades Ross has come to articulate a systematic approach to education consciously tailored for a new era of global interdependence.In this volume, world-renowned scholars from a variety of disciplines, as well as veteran teachers, administrators, and students, come together to examine some of the best practices in K-12 education in the context of an increasingly interconnected world. Together they explore how the Ross model of education, which cultivates in students a global perspective, aligns with broader trends in the arts, humanities, and sciences in the new millennium.Contributors: Nick Appelbaum, Ralph Abraham, Antonio M.

Metabolomic study of marine Streptomyces sp.: Secondary metabolites and the production of potential anticancer compounds
Resorting to a One Strain Many Compounds (OSMAC) approach, the marine Streptomyces sp. BRB081 strain was grown in six different media settings over 1, 2, 3 or 7 days. Extractions of mycelium and broth were conducted separately for each media and cultivation period by sonication using methanol/acetone 1:1 and agitation with ethyl acetate, respectively. All methanol/acetone and ethyl acetate crude extracts were analysed by HPLC-MS/MS and data treatment was performed through GNPS platform using MZmine 2 software. In parallel, the genome was sequenced, assembled and mined to search for biosynthetic gene clusters (BGC) of secondary metabolites using the AntiSMASH 5.0 software. Spectral library search tool allowed the annotation of desferrioxamines, fatty acid amides, diketopiperazines, xanthurenic acid and, remarkably, the cyclic octapeptides surugamides. Molecular network analysis allowed the observation of the surugamides cluster, where surugamide A and the protonated molecule corresponding to the B-E isomers, as well as two potentially new analogues, were detected. Data treatment through MZmine 2 software allowed to distinguish that the largest amount of surugamides was obtained by cultivating BRB081 in SCB medium during 7 days and extraction of culture broth. Using the same data treatment, a chemical barcode was created for easy visualization and comparison of the metabolites produced overtime in all media. By genome mining of BRB081 four regions of biosynthetic gene clusters of secondary metabolites were detected supporting the metabolic data. Cytotoxic evaluation of all crude extracts using MTT assay revealed the highest bioactivity was also observed for extracts obtained in the optimal conditions as those for surugamides production, suggesting these to be the main active compounds herein. This method allowed the identification of compounds in the crude extracts and guided the selection of best conditions for production of bioactive compounds.

First-Order General-Relativistic Viscous Fluid Dynamics
We present the first generalization of Navier-Stokes theory to relativity that satisfies all of the following properties: (a) the system coupled to Einstein’s equations is causal and strongly hyperbolic; (b) equilibrium states are stable; (c) all leading dissipative contributions are present, i.e., shear viscosity, bulk viscosity, and thermal conductivity; (d) nonzero baryon number is included; (e) entropy production is non-negative in the regime of validity of the theory; (f) all of the above hold in the nonlinear regime without any simplifying symmetry assumptions. These properties are accomplished using a generalization of Eckart’s theory containing only the hydrodynamic variables, so that no new extended degrees of freedom are needed as in Müller-Israel-Stewart theories. Property (b), in particular, follows from a more general result that we also establish, namely, sufficient conditions that when added to stability in the fluid’s rest frame imply stability in any reference frame obtained via a Lorentz transformation All of our results are mathematically rigorously established. The framework presented here provides the starting point for systematic investigations of general-relativistic viscous phenomena in neutron star mergers.

Touching the audience: musical haptic wearables for augmented and participatory live music performances
This paper introduces the musical haptic wearables for audiences (MHWAs), a class of wearable devices for musical applications targeting audiences of live music performances. MHWAs are characterized by embedded intelligence, wireless connectivity to local and remote networks, a system to deliver haptic stimuli, and tracking of gestures and/or physiological parameters. They aim to enrich musical experiences by leveraging the sense of touch as well as providing new capabilities for creative participation. The embedded intelligence enables the communication with other external devices, processes input data, and generates music-related haptic stimuli. We validate our vision with two concert-experiments. The first experiment involved a duo of electronic music performers and twenty audience members. Half of the audience used an armband-based prototype of MHWA delivering vibro-tactile feedback in response to performers’ actions on their digital musical instruments, and the other half was used as a control group. In the second experiment, a smart mandolin performer played live for twelve audience members wearing a gilet-based MHWA, which provided vibro-tactile sensations in response to the performed music. Overall, results from both experiments suggest that MHWAs have the potential to enrich the experience of listening to live music in terms of arousal, valence, enjoyment, and engagement. Nevertheless, results showed that the audio-haptic experience was not homogeneous across participants, who could be grouped as those appreciative of the vibrations and those less appreciative of them. The causes for a lack of appreciation of the haptic experience were mainly identified as the sensation of unpleasantness caused by the vibrations in certain parts of the body and the lack of the comprehension of the relation between what was felt and what was heard. Based on the reported results, we offer suggestions for practitioners interested in designing wearables for enriching the musical experience of audiences of live music via the sense of touch. Such suggestions point towards the need of mechanisms of personalization, systems able to minimize the latency between the sound and the vibrations, and a time of adaptation to the vibrations.

Impacts of forestation and deforestation on local temperature across the globe
Changing forest cover is a key driver of local climate change worldwide, as it affects both albedo and evapotranspiration (ET). Deforestation and forestation are predicted to have opposing influences on surface albedo and ET rates, and thus impact local surface temperatures differently. Relationships between forest change, albedo, ET, and local temperatures may further vary regionally, as the strengths of warming by albedo effects and cooling by ET effects vary with latitude. Despite these important relationships, the magnitude of forest cover effects on local surface temperature across the globe remains unclear. Using recently-released global forest change data, we first show that forestation and deforestation have pervasive and opposite effects on LST, ET and albedo worldwide. Deforestation from 2000 to 2010 caused consistent warming of 0.38 ± 0.02 (mean ± SE) and 0.16 ± 0.01°C in tropical and temperate regions respectively, while forestation caused cooling in those regions of -0.18 ± 0.02 and -0.19 ± 0.02°C. Tropical forests were particularly sensitive to the climate effects of forest change, with forest cover losses of ~50% associated with increased LST of 1.08 ± 0.25°C, whereas similar forest cover gains decreased LST by -1.11 ± 0.26°C. Secondly, based on a new structural equation model, we show that these changes on LST were largely mediated by changes in albedo and ET. Finally, based on this model, we show that predicted forest changes in Brazil associated with a business-as-usual land use scenario through 2050 may increase LST up to 1.45°C. Our results contribute to a better understanding of the mechanistic inter-relationships between forest change and changes in albedo, ET and LST, and provide additional evidence that forestation has the potential to reverse deforestation impacts on local climate, especially in tropical and temperate regions.
