Business Leadership in Global Climate Change Responses
Authors: Esty Daniel C. , Bell Michelle L. 
Published: April 2018

In the 2015 Paris Climate Change Agreement, 195 countries committed to reducing greenhouse gas emissions in recognition of the scientific consensus on the consequences of climate change, including substantial public health burdens. In June 2017, however, US president Donald Trump announced that the United States would not implement the Paris Agreement.We highlight the business community’s backing for climate change action in the United States. Just as the US federal government is backing away from its Paris commitments, many corporate executives are recognizing the need to address the greenhouse gas emissions of their companies and the business logic of strong environmental, social, and governance practices more generally.We conclude that climate change could emerge as an issue on which the business and public health communities might align and provide leadership.

Core IdeasExplored the impact of variables selected by different means on mapping at a watershed scale area.Identified influential topographic variables with appropriate scales for mapping soil properties.Finding the appropriate scales of local attributes is helpful for mapping soil properties accurately.Local attribute scale helped map accuracy vs. use of local and regional attributes at single scale.The influential environmental variables and their appropriate scales for mapping different soil properties are usually different. Comparisons between variables selected using machine learning and knowledge‐based approaches and their impacts for soil mapping are necessary to provide guidelines on selecting environmental variables. This study compared topographic variables with single and multiple scales selected for five soil properties (topsoil clay content, sand content, silt content, topsoil organic matter content (SOM), and soil depth) using a recursive feature elimination (RFE) algorithm and variables selected based on expert knowledge on mapping. One hundred and seventy‐three variables were generated including five single‐scale variables derived with a 3 × 3 neighborhood size and seven multi‐scale variables with various neighborhood sizes. Subsets 1 and 2 were selected from single‐scale variables (Pool 1) and all variables (Pool 2), respectively. A reference Subset 3 was selected based on soil pedogenesis knowledge. Results showed that variables in Subset 1 included both local and regional terrain attributes, but were considerably different to the reference variables. When considering scales, local variables at specific scales became the most important variables. Mapping accuracies using Subset 2 were the highest for all soil properties. This indicates that finding the appropriate scales of local attributes and using common local attributes with appropriate scales is more helpful than using both local and regional attributes at single scale for mapping soil properties accurately. The RFE approach is efficient for selection of variables. Also, the input environmental variables for selection determine whether the selected variables perform better than all input variables without selection for predicting soil properties.
New insights in morphological analysis for managing activated sludge systems

Published: April 2018

Abstract
In activated sludge (AS) process, the impact of the operational parameters on process efficiency is assumed to be correlated with the sludge properties. This study provides a better insight into these interactions by subjecting a laboratory-scale AS system to a sequence of operating condition modifications enabling typical situations of a wastewater treatment plant to be represented. Process performance was assessed and AS floc morphology (size, circularity, convexity, solidity and aspect ratio) was quantified by measuring 100,000 flocs per sample with an automated image analysis technique. Introducing 3D distributions, which combine morphological properties, allowed the identification of a filamentous bulking characterized by a floc population shift towards larger sizes and lower solidity and circularity values. Moreover, a washout phenomenon was characterized by smaller AS flocs and an increase in their solidity. Recycle ratio increase and COD:N ratio decrease both promoted a slight reduction of floc sizes and a constant evolution of circularity and convexity values. The analysis of the volume-based 3D distributions turned out to be a smart tool to combine size and shape data, allowing a deeper understanding of the dynamics of floc structure under process disturbances.

AbstractThis review is based on the adsorption characteristics of sorghum (Sorghum bicolor) for removal of heavy metals from aqueous media. Different parameters like pH, temperature of the medium, sorghum concentration, sorghum particle size, contact time, stirring speed and heavy metal concentration control the adsorption efficiency of sorghum biomass for heavy metal ions. Sorghum biomass showed maximum efficiency for removal of heavy metal ions in the pH range of 5 to 6. It is an agricultural waste and is regarded as the cheapest biosorbent, having high adsorption capacity for heavy metals as compared to other reported adsorbents, for the treatment of heavy metal polluted wastewater. Adsorption of heavy metal ions onto sorghum biomass follows pseudo second order kinetics. Best fitted adsorption isotherm models for removal of heavy metal ions on sorghum biomass are Langmuir and Freundlich adsorption isotherm models. Thermodynamic aspects of heavy metal ions adsorption onto sorghum biomass have also been elaborated in this review article. How adsorption efficiency of sorghum biomass can be improved by different physical and chemical treatments in future has also been elaborated. This review article will be highly useful for researchers working in the field of water treatment via biosorption processing. The quantitative demonstrated efficiency of sorghum biomass for various heavy metal ions has also been highlighted in different sections of this review article.
Veterans’ Perspectives on Fitbit Use in Treatment for Post-Traumatic Stress Disorder: An Interview Study
Authors: Ng Ada , Reddy Madhu , Zalta Alyson K , Schueller Stephen M 
Published: April 2018

BackgroundThe increase in availability of patient data through consumer health wearable devices and mobile phone sensors provides opportunities for mental health treatment beyond traditional self-report measurements. Previous studies have suggested that wearables can be effectively used to benefit the physical health of people with mental health issues, but little research has explored the integration of wearable devices into mental health care. As such, early research is still necessary to address factors that might impact integration including patients' motivations to use wearables and their subsequent data.ObjectiveThe aim of this study was to gain an understanding of patients’ motivations to use or not to use wearables devices during an intensive treatment program for post-traumatic stress disorder (PTSD). During this treatment, they received a complementary Fitbit. We investigated the following research questions: How did the veterans in the intensive treatment program use their Fitbit? What are contributing motivators for the use and nonuse of the Fitbit?MethodsWe conducted semistructured interviews with 13 veterans who completed an intensive treatment program for PTSD. We transcribed and analyzed interviews using thematic analysis.ResultsWe identified three major motivations for veterans to use the Fitbit during their time in the program: increase self-awareness, support social interactions, and give back to other veterans. We also identified three major reasons certain features of the Fitbit were not used: lack of clarity around the purpose of the Fitbit, lack of meaning in the Fitbit data, and challenges in the veteran-provider relationship.ConclusionsTo integrate wearable data into mental health treatment programs, it is important to understand the patient’s perspectives and motivations in using wearables. We also discuss how the military culture and PTSD may have contributed to our participants' behaviors and attitudes toward Fitbit usage. We conclude with possible approaches for integrating patient-generated data into mental health treatment settings that may address the challenges we identified.

Este trabalho buscou identificar as memórias e as identidades que vendedores de farinha em feiras do bairro do Guamá, na cidade de Belém (PA), apresentam sobre os processos de produção, comercialização e consumo desse produto. O caminho metodológico percorrido se estabeleceu por meio de uma abordagem qualitativa, com pesquisas bibliográficas, documentais e de campo. Mediante uma aproximação etnográfica, foram realizadas observações sistemáticas, conversas informais, registros fotográficos, aplicação de formulários e de entrevistas. Os dados coletados revelam que, mais do que a importância econômica, a farinha é conferida como um elemento essencial no universo cultural paraense, visto que contribui na composição das identidades e memórias do paraense. Contudo, devido aos reajustes intensos no preço da farinha, houveram muitas reclamações dos consumidores e até substituição da farinha por outros produtos. Esse cenário, que está a se desenhar sobre as práticas ligadas à farinha, têm provocado significativas perdas nas memórias e crises na identidade do paraense.Palavras-chave: Memória. Identidade.

Published: April 2018

O objetivo do presente texto será mostrar a “pesquisadora” em seu campo de trabalho, numa etnografia marcada por dois instantes e contextos diferentes: Brasil e Portugal. Num primeiro instante a pesquisa foi realizada com muçulmanos no Brasil, onde foram analisados os processos de “conversão” dos brasileiros ao Islã. Posteriormente, a investigação se estendeu às práticas religiosas dos “convertidos”, bem como as suas inserções entre os grupos muçulmanos no Brasil e em Portugal, resultando num trabalho comparativo entre os dois países. Foram, ambas as pesquisas, marcadas pelas “diferenças”, que transformaram-se em motivação, limitações e reflexões. O “pesquisado” e “pesquisador” encontraram-se numa etnografia, ou numa “viagem”, que implicou ambiguidades e deixou marcas e sentimentos gravados. Cheiros e sensações que ficaram guardados como lembranças dos momentos em campo.Palavras Chave: Islã. Muçulmanos. Conversão.Work field: ethnographic reportsAbstractThis paper shows the "researcher" in his field into an ethnography pointed by two moments and contexts: Brazil and Portugal. At the first moment the research was with Muslims in Brazil. It analyzes the "conversion" from Brazilians to Islam. Later, the investigation was extended to the religious practices of "converted", and their inserts between Muslim groups both in Brazil and Portugal what resulted in a comparative study between the two countries. Both surveys were marked by the "differences" which turned into motivation, limitations and reflections. The "researched" and "researcher" met themselves into an ethnography, or a "trip", which implied ambiguities and left marks and feelings.

Redecriar moeda flor: tempos de trabalho social na Ilha das Flores (Porto Alegre, RS, Brasil)
Authors: Jaeger Foresti Andréa 
Published: April 2018

O artigo refere-se ao relato de uma mestranda de Engenharia Civil da UFRGS que estabelece um diálogo interdisciplinar com a Antropologia, expondo sua experiência como gestora de uma Organização Não-Governamental que desenvolve projetos socioambientais. Na busca de reflexões sobre as estratégias de intervenção social, realizadas por meio da ONG no Delta do Jacuí, uma área caracterizada como Unidade de Conservação mista na capital gaúcha - Porto Alegre - RS, o relato da experiência com um grupo de moradores de áreas precárias em situação de risco de inundação na Ilha das Flores é examinado com base em conceitos antropológicos. As reflexões fundamentadas na Teoria da Dádiva, de Marcel Mauss, permitiram avaliar a necessidade de se pensar numa reconfiguração da sociedade. Essa reconfiguração pressupõe o reconhecimento das necessidades de cada cidadão em pequenos núcleos comunitários, e que esse reconhecimento se propague de forma local, iniciando com o estímulo à participação comunitária e se expanda geograficamente, em rede, até alcançar dimensões globais. Palavras-chave: Moeda; participação; ONG.Redecriar and the “flower-coin”: the times of social work at Ilha das Flores (Porto Alegre, RS, Brazil)AbstractThe article refers to the report of a master student of Civil Engineering Graduate Program at the Federal University of Rio Grande do Sul that establishes an interdisciplinary dialogue with Anthropology, exposing her experience as manager and founder of a Non-Governmental Organization that develops social and environmental projects. In search of reflections on the social intervention strategies carried out by the NGO in the Jacuí Delta, an area characterized as mixed conservation area in the metropolitan region of Porto Alegre, RS, the account of the experience with a group of residents living in poor areas in flood risk of Flores Island is examined on the basis of anthropological concepts. The reflections based on the Gift Theory by Marcel Mauss made possible to take in consideration the need of thinking a new configuration of the society. This reconfiguration implies the recognition of the needs of every citizen in small community centers, and that this recognition spreads locally, starting with the encouragement of community participation and expanding geographically, in a network, to achieve global dimensions.Key words: Currency, participation, NGOs.
Envelhecer na invisibilidade: tempo e narrativa na Ponta Oeste da Ilha do Mel, Paraná, Brasil
Authors: Harder Eduardo , De Castro Freitas Ana Elisa 
Published: April 2018

Os sentidos do tempo na Ponta Oeste da Ilha do Mel despontam nas narrativas de pessoas cuja vida é conjugada no pretérito. Nesta antiga coletividade de pescadores artesanais, localizada no complexo estuarino lagunar de Iguape, Cananéia e Paranaguá, o futuro perdeu seu elo com as novas gerações. Encravada entre o mar e a unidade de conservação da natureza de proteção integral Estação Ecológica da Ilha do Mel, a história da Ponta Oeste, narrada por seus moradores, revela os impactos de três décadas de políticas conservacionistas e restrição territorial pelo Estado. O tempo se dilui e reconfigura no espaço da existência de sujeitos que se percebem simultaneamente na invisibilidade e em processo de envelhecimento. As rupturas e continuidades do pertencimento ao território tecem uma fina narrativa, em que a mobilização pela vida futura busca os fios de sua trama na memória e nas imagens do tempo passado. Palavras-chave: Ponta Oeste da Ilha do Mel. Paisagens Culturais. Memória. Narrativa. Conservação da naturezaAging in invisibility: time and narrative in the Ponta Oeste da Ilha do Mel, Paraná, Brazil.AbstractThe sense of time in the Ponta Oeste of Ilha do Mel emerges in the narratives of people whose lives are conjugated in the past tense. This ancient community of artisanal fishermen, located in the estuarine lagoon complex of Iguape, Cananéia and Paranaguá, the future has lost its link with the new generations. Nestled between the sea and the protected area of the strictly protected nature of Ilha do Mel Ecological Station, the history of Ponta Oeste, narrated by its inhabitants, reveals the impact of three decades of conservation policies and territorial restriction by the state. The time diluted in space and reconfigures the existence of subjects who perceive both invisibility and the aging process. The ruptures and continuities of belonging to the territory weave a thin narrative, in which the mobilization for the afterlife search the threads of his plot in memory and the images of the past time.Key words: Ponta Oeste of Ilha do Mel.
