Cenários de Contaminação da Água Subterrânea por Atividades Agrícolas
Authors: Ribeiro Maria Lúcia , Lourencetti Carolina , Teixeira Denilson 
Published: November 2017

As águas subterrâneas são utilizadas em muitos países como água potável e vem apresentando acréscimo no seu consumo devido à boa qualidade e baixo custo de tratamento comparado ao da água superficial. Por estarem localizadas em reservatórios que apresentam, em alguns casos, vulnerabilidade natural à contaminação, as mesmas podem apresentar sua qualidade alterada devido ao uso inadequado do solo. A atividade agrícola é umas das atividades que podem ocasionar prejuízos à qualidade dessas águas. Esse fato pode ser observado pela ocorrência de contaminantes inorgânicos e orgânicos em amostras de águas subterrâneas de diversos países. Medidas preventivas devem ser tomadas com o objetivo de minimizar e até mesmo eliminar esse risco de contaminação. Esse trabalho apresenta uma revisão dos principais cenários referentes à contaminação e proteção das águas subterrâneas, discutindo particularmente os potenciais contaminantes gerados pelas atividades agrícolas.

RANCANGAN MODEL PENGEMBANGAN KEWIRAUSAHAAN PADA MAHASISWA DITINJAU DARI PERSEPSI, MINAT DAN KOMPETENSI KEWIRAUSAHAAN
Authors: Prajogo Uke 
Published: November 2017

Pengelolaan sumber daya alam belum maksimal, ketersediaan lapangan pekerjaan juga belum bisa menampung angkatan kerja yang ada. Yang lebih memprihatinkan lagi adalah sedikitnya jumlah wirausahawan, padahal untuk menjadi sebuah bangsa maju dan mandiri suatu negara harus mempunyai sedikitnya 2% wirausahawan dari jumlah penduduk. Indonesia sampai saat ini hanya memiliki 0,18% wirausaha, artinya masih sangat sedikit masyarakat Indonesia yang memiliki mental kreatif, inovatif dan tidak mengandalkan hidupnya dengan mencari pekerjaan. Perlu dibangun masyarakat yang memiliki mental pencipta lapangan pekerjaan, salah satunya bisa didorong dengan mengembangkan program pendidikan entrepreneurship (kewirausahaan) yang dimulai pada usia dini.
Tujuan penelitian ini adalah untuk mencari model pengembangan kewirausahaan pada mahasiswa yang didasarkan pada 1) persepsi mahasiswa terhadap kewirausahaan, 2) minat mahasiswa terhadap kewirausahaan, 3) kompetensi yang dibutuhkan mahasiswa dalam hal kewirausahaan. Mengambil lokasi penelitian di Malang, dengan informan dari tiga perguruan tinggi besar yang ada, diharapkan bisa mewakili karakter mahasiswa pada umumnya. Menggunakan metode deskriptif kualitatif, penelitian ini menghasilkan model-model pengembangan kewirausahaan pada mahasiswa yang didasarkan pada persepsi, minat dan kompetensi yang dimiliki saat ini.

Cadre juridique imprécis, niveau d’exigence faible : quelle place pour l’efficacité de l’action ?
Authors: Buffet Jacky , Camous David-André 
Published: November 2017

La coopération décentralisée s’est historiquement construite autour d’un document juridique unique – la convention de coopération – au contenu flou et peu contraignant. Alors que la montée en puissance de l’action internationale des collectivités territoriales françaises aurait pu militer en faveur d’un document plus exigeant en termes d’engagement et de responsabilités, le législateur a préféré s’orienter vers une formule plus souple en le rendant facultatif, voire en le supprimant. Cet article interroge les motivations d’une telle évolution et envisage ses conséquences éventuelles en termes d’« asymétrie » entre « prestataires » et « bénéficiaires », de faibles incitations à la recherche d’efficacité des actions menées et finalement de responsabilité morale et juridique molle face aux bilans contrastés susceptibles d’en découler. De telles évolutions ne suggèrent-elles pas la construction d’un modèle « libertaire » de coopération ?
De la coopération décentralisée à l’action internationale des collectivités : un paradigme économique ?
Authors: Rozier Hadrien 
Published: November 2017

L’action internationale des territoires s’était affirmée sur la base d’une pratique solidaire de la coopération décentralisée. Poursuivant des objectifs de rayonnement, les collectivités investissent aujourd’hui l’international dans l’intérêt de leur développement économique. L’observation de plusieurs acteurs appréhendant l’avènement d’un paradigme est-elle pour autant pertinente ? Un changement de paradigme intervient lorsqu’un schéma ne parvient plus à résoudre les anomalies rencontrées, amenant l’idée d’un nouveau modèle à suivre. Si l’idée d’une rupture soudaine ne peut être généralisée, quatre dynamiques marquent une évolution vers de nouveaux principes d’action de l’AICT, acquis au développement local : des territoires plus compétents et responsables sur le plan économique, l’intégration des structures économiques locales dans un système mondialisé, l’appropriation de ces enjeux par les élus et les techniciens, les limites mêmes de la coopération décentralisée.
L’internationalisme municipal comme vecteur de démocratisation
Authors: Kuokštyt˙ Ringail˙ 
Published: November 2017

L’article s’intéresse à la ville lituanienne de Kaunas, capitale de la Lituanie pendant l’entre-deux-guerres. Cette période fut un moment historique pour le pays, devenu indépendant, et pour les résidents de Kaunas tout particulièrement : la ville se développe en rapport avec la modernité occidentale pour devenir une ville européenne, y compris grâce à l’action extérieure de la municipalité. Malgré des apports techniques et disciplinaires, l’internationalisme municipal permet à la ville de Kaunas de développer, en dépit de tendances centralisatrices, une dynamique locale propre de démocratisation, illustrée par l’importance dont se dote progressivement le rapport, entendu en termes d’ouverture, de la municipalité à la presse. Cette évolution, même si non intentionnée, comporte une signification empirique importante : elle modifie la logique d’interaction entre les autorités municipales et ses administrés et se veut politique.
The Social Life of Policy Reports
Authors: Jamar Astrid 
Published: November 2017

Adopting a Latourian approach, this article examines the social role played by policy reports, which are produced and used in the everyday implementation of transitional justice, using the Gacaca Courts in Rwanda as a case study. As glossy end products, transitional justice reports create the image of more efficient processes unaffected by difficult politics. The article traces the journey of Gacaca policy reports and the shift from their envisioned role to their actual performed functions: considered as technical safeguards, reports become central tools in the transitional justice battlefield – almost as if reports were used as weapons while arguing about the past and the nature of the transition. Since transitional justice processes mostly culminate in the production of reports which presume to clarify and make accountable complex legacies of violence, such an analysis contributes significantly to addressing the construction of transitional justice narratives critically. Given the ubiquity of reports in aid-dependent policy implementation, this article draws attention to often glossed-over aspects of complex politics and to the contentious role played by international aid organisations. By doing so, the paper encourages discussions about the materiality of international aid and its social consequences.

Newfoundland & Labrador: Rolling Blackouts, The Liberty Reports, & The Role of Reliability in Energy Provision
Authors: Kind Sydni 
Published: November 2017

Newfoundland’s electrical system experienced significant outage periods in January 2013 and January 2014 that left a large portion of the Island population without power for days at a time. The inability of the electric system to maintain operations, even considering record winter weather occurrences, raised concerns with consumers and the government about the ability of the system to survive long-term. Newfoundland’s energy sector operates as a monopoly system, partially owned and operated by the Crown. Lacking a connection to the mainland system on the Island portion of the province, there is a level of self-reliance placed on the system that is uncommon in North America. The paper discusses the Board of Commissioners of Public Utilities’ authority to commence an investigation and the resulting Liberty Consulting Group report that analyzed the system and its areas of improvement. The Newfoundland system’s lack of reliability standards is compared to the standards of the North America Electric Reliability Corporation, as well as the Ontario and Alberta systems. It concludes with the forward-looking consideration of the Muskrat Falls Development and its potential to positively impact the Newfoundland electrical system.
Exceptional Air Mass Transport and Dynamical Drivers of an Extreme Wintertime Arctic Warm Event

Published: November 2017

AbstractAt the turn of the years 2015/2016, maximum surface temperature in the Arctic reached record‐high values, exceeding the melting point, which led to a strong reduction of the Arctic sea ice extent in the middle of the cold season. Here we show, using a Lagrangian method, that a combination of very different airstreams contributed to this event: (i) warm low‐level air of subtropical origin, (ii) initially cold low‐level air of polar origin heated by surface fluxes, and (iii) strongly descending air heated by adiabatic compression. The poleward transport of these warm airstreams occurred along an intense low‐level jet between a series of cyclones and a quasi‐stationary anticyclone. The complex 3‐D configuration that enabled this transport was facilitated by continuous warm conveyor belt ascent into the upper part of the anticyclone. This study emphasizes the combined role of multiple transport processes and transient synoptic‐scale dynamics for establishing an extreme Arctic warm event.

ObjectiveTo identify patient demographic and clinical characteristics associated with osteoarthritis (OA) treatment use.MethodsThis was a secondary data analysis of 3 clinical trials among patients with hip or knee OA conducted in Duke Primary Care practices, the Durham Veterans Affairs (VA) Health Care System, and the University of North Carolina–Chapel Hill (UNC). At baseline, participants reported sociodemographic characteristics, OA‐related pain and function, and OA treatment use, including oral analgesics, topical creams, joint injections, and physical therapy. Separate, multivariable logistic models (adjusted for clustering of clinics and providers for the Duke and VA cohorts) were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the associations between participant characteristics and each type of OA treatment.ResultsOral analgesic use was reported by 70–82% of participants across the 3 cohorts. Physical therapy, knee injections, and topical creams were used by 39–52%, 55–60%, and 25–39% of Duke, VA, and UNC participants, respectively. In multivariable models, worse pain, stiffness, and function, per 5‐unit increase, were associated with greater odds of using any oral analgesic for the cohorts from Duke (OR 1.18 [95% CI 1.08–1.28]) and UNC (OR 1.14 [95% CI 1.05–1.24]), but not for the VA cohort (OR 1.04 [95% CI 0.95–1.14]). For all 3 cohorts, nonwhites had higher odds of using topical creams compared to whites.ConclusionResults suggest potential underutilization of therapies other than oral analgesics. Patient characteristics may affect OA treatment use, and understanding the relationship between these factors and OA treatment preferences may improve adherence to OA treatment guidelines.
Robust centralized and weighted measurement fusion white noise deconvolution estimators for multisensor systems with mixed uncertainties
Authors: Liu Wen‐Qiang , Wang Xue‐Mei , Deng Zi‐Li 
Published: November 2017

SummaryEstimating the input signal of a system is called deconvolution or input estimation. The white noise deconvolution has important applications in oil seismic exploration, communications, and signal processing. This paper addresses the design of robust centralized fusion (CF) and weighted measurement fusion (WMF) white noise deconvolution estimators for a class of uncertain multisensor systems with mixed uncertainties, including uncertain‐variance multiplicative noises in measurement matrix, missing measurements, and uncertain‐variance linearly correlated measurement and process white noises. By introducing the fictitious noise, the considered system is converted into one with only uncertain noise variances. According to the minimax robust estimation principle, based on the worst‐case system with the conservative upper bounds of uncertain noise variances, the robust CF and WMF time‐varying white noise deconvolution estimators (predictor, filter, and smoother) are presented in a unified framework. Applying the Lyapunov equation approach, their robustness is proved in the sense that their actual estimation error variances are guaranteed to have the corresponding minimal upper bounds for all admissible uncertainties. Using the information filter, their equivalence is proved. Their accuracy relations are proved. The computational complexities are analyzed and compared. Compared with the CF algorithm, the WMF algorithms can significantly reduce the computational burden when the number of sensors is larger. The corresponding robust fused steady‐state white noise deconvolution estimators are also presented. A simulation example with respect to the multisensor IS‐136 communication systems shows the effectiveness and correctness of the proposed results.

AbstractRenal‐clearable nanoparticles have made it possible to overcome the toxicity by nonspecific accumulation in healthy tissues/organs due to their highly efficient clearance characteristics. However, their tumor uptake is relatively low due to the short blood circulation time and rapid body elimination. Here, this problem is addressed by developing renal‐clearable nanoparticles by controlled coating of sub‐6 nm CuS nanodots (CuSNDs) on doxorubicin ladened mesoporous silica nanoparticles (pore size ≈6 nm) for multimodal application. High tumor uptake of the as‐synthesized nanoparticles (abbreviated as MDNs) is achieved due to the longer blood circulation time. The MDNs also show excellent performance in bimodal imaging. Moreover, the MDNs demonstrated a photothermally sensitive drug release and pronounced synergetic effects of chemo‐photothermal therapy, which were confirmed by two different tumor models in vivo. A novel key feature of the proposed synthesis is the use of renal‐clearable CuSNDs and biodegradable mesoporous silica nanoparticles which also are renal‐clearable after degradation. Therefore, the MDNs would be rapidly degraded and excreted in a reasonable period in living body and avoid long‐term toxicity. Such biodegradable and clearable single‐compartment theranostic agents applicable in highly integrated multimodal imaging and multiple therapeutic functions may have substantial potentials in clinical practice.

AbstractA novel small‐molecule acceptor, (2,2′‐((5E,5′E)‐5,5′‐((5,5′‐(4,4,9,9‐tetrakis(5‐hexylthiophen‐2‐yl)‐4,9‐dihydro‐s‐indaceno[1,2‐b:5,6‐b′]dithiophene‐2,7‐diyl)bis(4‐(2‐ethylhexyl)thiophene‐5,2‐diyl))bis(methanylylidene)) bis(3‐hexyl‐4‐oxothiazolidine‐5,2‐diylidene))dimalononitrile (ITCN), end‐capped with electron‐deficient 2‐(3‐hexyl‐4‐oxothiazolidin‐2‐ylidene)malononitrile groups, is designed, synthesized, and used as the third component in fullerene‐free ternary polymer solar cells (PSCs). The cascaded energy‐level structure enabled by the newly designed acceptor is beneficial to the carrier transport and separation. Meanwhile, the three materials show a complementary absorption in the visible region, resulting in efficient light harvesting. Hence, the PBDB‐T:ITCN:IT‐M ternary PSCs possess a high short‐circuit current density (Jsc) under an optimal weight ratio of donors and acceptors. Moreover, the open‐circuit voltage (Voc) of the ternary PSCs is enhanced with an increase of the third acceptor ITCN content, which is attributed to the higher lowest unoccupied molecular orbital energy level of ITCN than that of IT‐M, thus exhibits a higher Voc in PBDB‐T:ITCN binary system. Ultimately, the ternary PSCs achieve a power conversion efficiency of 12.16%, which is higher than the PBDB‐T:ITM‐based PSCs (10.89%) and PBDB‐T:ITCN‐based ones (2.21%). This work provides an effective strategy to improve the photovoltaic performance of PSCs.
