O poder de barganha político chinês e o reordenamento político e ecônomico global: a macro estratégia e a inversão de habilidades no caso das terras raras
Authors: Leite Alexandre César Cunha , Araújo Mércia Cristina Gomes de , Pautasso Diego
Published: October 2019

Pretende-se com esse ensaio realizar uma análise do poder de barganha política logrado pela China no contexto de ascensão do seu mercado de commodities, tratando-se de modo particular sobre os Elementos Terras Raras (ETR). Considera-se não apenas a posição de liderança de mercado alcançada, mas também a posição política oriunda da ação econômica alcançada pelo Estado chinês no atual cenário. Trata-se adicionalmente da macroestratégia chinesa que resulta nas escolhas operacionais internas que dão suporte natural a sua economia. Grosso modo, salienta-se a primazia de suas decisões internas, sobretudo no tangente a sua política industrial e desenvolvimento econômico nacional, e argumenta-se que com o monopólio absoluto dos minérios estratégicos a China passou a ser vista no setor como uma eminente ameaça comercial a muitos outros países, desenvolvidos ou em desenvolvimento. Metodologicamente a pesquisa adquire uma roupagem bibliográfica e caráter indutivo.

Abstract: The aim of this essay is to conduct an analysis of the political bargaining power achieved by China in the context of the rise of its commodity market, regarding to Rare Earth Elements (ETRs). It is considered not only the market position achieved in the current leadership but also the political position stemming from economic action on the elements achieved by the Chinese state in the current scenario. It is additionally the Chinese macro strategy that results in the internal operational choices that give natural support to its economy. The primacy of its domestic decisions, particularly in terms of its industrial policy and national economic development, is accentuated, and it is argued that with the absolute monopoly of strategic ores China has come to be seen in the sector as an eminent commercial threat to many other countries, developed or developing. Methodologically the research acquires a bibliographical and inductive character.
Keywords: Bargaining power. Elements of Rare Earths. China.

The BRICS Group and Global Economic Governance
Authors: Montoute Annita Deloris
Published: October 2019

Bolstered by the 2008 global financial crisis, and the BRICS’ increased economic weight, the latter has called for change to global economic governance. The BRICS critique and proposals are towards a re-structuring of global economic governance to reflect their increasing weight in the global political economy rather than replacing the principles and philosophy (ideas)—explicitly or implicitly—undergirding the neoliberal economic order. The changes being proposed can be likened to Hall’s first and second order change which simply re-arranges existing policy without bringing about radical changes. The paper argues that the conditions necessary for third order change - radical policy change or a paradigm shift - do not exist to provide the BRICS with a framework for challenging global economic governance. These include: (a) the lack of expert consensus on the cause of the crisis and the absence of a sufficiently coherent and unified body of ideas to form an alternative model; and (b) asymmetries in elements of the research process between those which support the neo liberal agenda and those which provide counter perspectives.   

Key words: BRICS; global economic governance; neoliberalism; paradigm maintenance; ideas; policy adjustments.

As relações entre Brasil e Cuba: das vantagens econômicas à retração política
Authors: Bressan Regiane Nitsch
Published: October 2019

O trabalho apresenta a evolução da relação bilateral entre Brasil e Cuba entre 2008 e 2016, superando a distância entre os países. A política externa do governo de Lula foi propositiva às relações regionais, fomentou integração latino-americana a partir da CELAC, que inclui Cuba no diálogo regional, e efetuou aproximação política, econômica e ideológica entre os dois países. A política externa de Rousseff sucedeu-se em termos pragmáticos, assegurando ganhos a ambos os países. Entre eles: os investimentos brasileiros na modernização do Porto de Mariel e a construção da Zona Econômica; o crescimento singular do comércio bilateral e instalação de empresas brasileiras na ilha; além da cooperação na área da saúde, o recrutamento de 11.429 médicos para atuarem em áreas carentes do território brasileiro. A densidade e natureza pragmática desta relação foram fundamentais para a consolidação da política entre Brasil e Cuba, mas enfrenta entraves do governo de Michel Temer, cuja política externa é guinada aos países do Norte, sendo possível identificar retrocesso no empenho brasileiro nos projetos regionais, estremecendo as relações com os países latino-americanos, inclusive com Cuba.

Palavras-Chaves: Brasil; Cuba; Relações Internacionais; América Latina.  

 

 

Abstract: This paper gives an overview of the evolution of bilateral relations between Brazil and Cuba from 2008 to 2016, overcoming the distance that separates the countries. The foreign policy pursued by the Lula government (2003-2011) focused on strengthening regional relations and promoting Latin American integration through CELAC, which includes Cuba in the regional dialogue, and establishing political, economic and ideological links between the two countries. Rousseff's foreign policy continued on a pragmatic course, ensuring gains for both countries. Examples of this are the Brazilian investments in the Mariel seaport modernisation and Special Economic Zone project, the growth of bilateral trade, and the installation of Brazilian companies on the island. Furthermore, cooperation was established in the health sector, involving the recruitment of 11.429 Cuban physicians to work in underdeveloped regions of Brazil. The density and pragmatic nature of this relationship have been fundamental for the consolidation of the bilateral relations between Brazil and Cuba, but faces the constraints of the recent Temer government, whose foreign policy is more directed to the northern countries and a decrease in Brazil's commitment to regional relations and integration projects can be observed, including those with Cuba.

Key words: Brazil; Cuba; International Relations; Latin America.

A gestão da crise financeira de 2008 pela China: o papel do Estado na implementação de políticas anticíclicas e desafios subsequentes
Authors: Marcussi Pontes Rúbia
Published: October 2019

O caráter sistêmico da crise financeira e econômica de 2008 demandou que rápidas políticas fossem implementadas pelos Estados para contrabalancear o alto nível de incerteza, a iliquidez e a queda na demanda agregada. Nesse sentido, a atuação da República Popular da China é considerada um caso extremamente relevante de estudo a partir do conjunto de medidas anticíclicas adotadas principalmente a partir de uma política fiscal ativa. O presente artigo busca, portanto, investigar o papel do Estado chinês na gestão da crise recente a partir da perspectiva Minskyana, reforçando a importância do big government e do big bank para a rápida recuperação econômica chinesa – embora não sem novos desafios.

Palavras-chave: crise financeira e econômica, China, políticas públicas anticíclicas, big government, big bank.

 

 

Abstract: The systemic effects of the financial and economic crisis of 2008 required the quick implementation of public polices to counterbalance the high level of uncertainty, illiquidity and the fall in the aggregate demand. The response of the Popular Republic of China is considered unique and worthy of investigation regarding the implementation of anti-cyclical public polices, with highlight to the role of its active fiscal police. Therefore, this articles aims to investigate the role of the Chinese state in the crisis management within Minsky’s perspective, recalling the importance of the big government and of the big bank for the quick economical response of China – although not without upcoming challenges.

Keywords: financial and economic crisis, China, anti-cyclical public policies, big government, big bank.

Nordeste Asiático como Eixo das Disputas Hegemônicas: competição e desestruturação da ordem regional
Authors: Brites Pedro Vinícius Pereira
Published: October 2019

A região do Nordeste Asiático destaca-se por sua singularidade geopolítica. É uma região na qual predominam atores cujas ações possuem alcance global, mesmo quando se trata da Coreia do Norte, o país mais pobre da região. Além da Coreia do Norte, as interações entre China, Rússia, Japão, Coreia do Sul, e Estados Unidos como potência extrarregional com presença militar na região, afetam a distribuição de poder no Sistema Internacional. A consolidação da China como Grande Potência reconfigurou a região e tem evidenciado o papel crucial que esse subsistema regional exerce para a polaridade no século XXI. Nos últimos anos, a consolidação do programa nuclear norte-coreano, a ascensão de Xi Jinping na China, a busca por reafirmação japonesa, a chegada de Donald Trump ao poder, reorientam as relações regionais. O presente artigo procura discutir as transformações na ordem regional no Nordeste Asiático desde o final da Guerra Fria até seus desdobramentos recentes e seus efeitos sobre as disputas hegemônicas. Assim, avaliam-se os processos que vêm ampliando a tendência à militarização e competição na região e o papel que a dissuasão nuclear exerce como fator determinante para o balanço regional.

 

 

Abstract: The region of Northeast Asia stands out for its geopolitical singularity. It is a region dominated by actors whose actions are global in scope, even when it comes to North Korea, the region's poorest country. In addition to North Korea, interactions between China, Russia, Japan, South Korea, and the United States as an extra-regional power with military presence in the region affect the distribution of power in the International System. The consolidation of China as a Great Power has reconfigured the region and has highlighted the crucial role that this regional subsystem plays in polarity in the twenty-first century. In recent years, the consolidation of North Korea's nuclear program, the rise of Xi Jinping in China, the search for Japanese reaffirmation, reorient regional relations. This article discusses the transformations in the regional order in Northeast Asia from the end of the Cold War until its recent unfolding and its effects on the hegemonic disputes. Thus, are evaluated the processes that have been increasing the tendency towards militarization and competition in the region and the role that nuclear deterrence plays as a determining factor for the regional balance.

Keywords: Northeast Asia; Hegemonic Recomposition; Regionalism.

Hierarquia Organizacional: uma Crítica de Poder e Interdependência
Authors: Estre Felipe Bernardo
Published: October 2019

O artigo faz uma crítica de Poder e interdependência, publicada em 1977 por Robert Keohane e Joseph Nye, com o objetivo de desvelar o teor normativo da obra. Argumenta-se que, ao contrário do que os autores afirmam, os novos processos políticos que caracterizam a política internacional desde o início do século XX não necessariamente resultaram na diminuição da hierarquia no sistema internacional. Pelo contrário, as organizações internacionais permitem a articulação de outras formas de discriminação entre os Estados que não podem ser resumidas a fatores econômicos ou assimetrias de poder. O cerne da discussão sobre a hierarquia na obra de Keohane e Nye está no próprio conceito de interdependência complexa, o qual divide o sistema internacional entre os “avançados” e aqueles que não podem fazer parte desse grupo. As organizações internacionais, portanto, não seriam fatores que diminuiriam a hierarquia no sistema internacional, mas reproduziriam discriminações por meio da atribuição de “capacidades dependentes de organizações”.

 

 

Abstract: The article is a critic Power and Interdependence, published in 1977 by Robert Keohane and Joseph Nye, with the goal of exposing the normative content of the book. It is argued that, contrary to what the authors say, the new political processes that characterize international politics since the beginning of the twentieth century did not result necessarily in the decrease of international hierarchy. On the contrary, international organizations allow the articulation of other forms of discrimination among the states that cannot be reduced to economic factors or asymmetries of power. The core discussion about hierarchy in the work of Keohane and Nye is on the very concept of complex interdependence, which divides the international system between the "advanced" and those that cannot join this group. Therefore, international organizations would not be factors that decrease the hierarchy in the international system but reproduce discrimination through the allocation of “organizationally dependent capabilities”.

Key words: Interdependence; hierarchy; international order.

De Copenhagen a Paris: a evolução do BASIC no complexo de Regime de Mudanças Climáticas
Authors: Silveira Mariana Balau
Published: October 2019

O fracasso do Protocolo de Kyoto em desenvolver uma estrutura de governança climática eficaz e inclusiva provocou um movimento de multiplicação de agrupamentos no âmbito do Regime Internacional de Mudanças Climáticas (RIMC), como o BASIC. A mudança e gradual fragmentação do regime evidencia o seu caráter não-hierárquico e não-integrado – podendo ser denominado, portanto, um “complexo de regime”. A iminência de reforma na estrutura institucional, com a COP 21 como marco importante, porém, representa a transição de uma estratégia top-down anterior para uma abordagem bottom-up cujo foco reside na contribuição nacional dos países. O principal argumento do presente artigo, a partir de uma análise comparativa longitudinal das COPs, é de que esse movimento indicaria uma fragmentação gradual do BASIC enquanto coalizão de negociação política, ao mesmo tempo em que sugere novos rumos para o regime.

 

 

 

Abstract: The failure of the Kyoto Protocol in developing an effective and inclusive climate governance structure caused the multiplication of groups, such as the BASIC countries, under the International Climate Change Regime (UNFCCC).  Its gradual fragmentation shows the non-hierarchical character of this “regime complex”. The imminent reform of the institutional framework, with COP 21 as an important landmark, however, represents the transition from a previous top-down strategy to a bottom-up approach where the focus lies in national contributions rather than a broader accord. The main argument of this article, based on a longitudinal comparative analysis of the COPs, is that this movement would indicate a gradual fragmentation of BASIC as a political bargaining coalition, while suggesting new directions for the UNFCCC.

Key-words: BASIC, Climate Change, Paris Agreement.

The liberal peace and its contesting universal values: a theoretical approach to the development of hybrid forms of political order in post conflict societies
Authors: Pereira Mariana Morena
Published: October 2019

The Liberal Peace can be understood as a discourse and a framework which is constantly used by western countries in order to promote political stability in post-conflict societies. Embedded in the peacebuilding/peacekeeping operations, some liberal values are assumed to be the “only deal in town” to assist war-torn societies reaching political order. The present essay aims to analyze what are the theoretical principles embedded in the Liberal Peace assumptions and bring a critical approach which contests these universal values of implementing peace in transitioning societies. That being said, we can affirm that many values regarded as “universal” do not have much meaning to local societies in post-conflict states. The essay hence tries to look to an alternative perspective to build the peace in post-conflict societies: the hybrid peace. The Hybrid Peace assumption is an important approach which assumes that the local agency is a relevant actor on the promotion of peace in their respective communities, mainly in post-colonial states. Thus, the local actors have legitimacy and recognition of the society and can, therefore, promote and build peace along international interveners. The main objective of the present essay is to present a new approach to understand the peacebuilding projects and also recognize that different contexts need distinct approaches.

Kaum Milenial & Kebudayaan Nias
Authors: Telaumbanua Tuhoni
Published: October 2019

This article is intended to explicate how to assist the millennial generation of Ono Niha not to be uprooted from the Nias identity amid globalization and encourage them to participate in preserving Niasan culture. Through the social-historical analysis, this article appeals to the millennial generation not to be alienated from their own culture but participate in cultural conservation. Therefore, it is crucial to conduct a dialogue with millennials by presenting their origins, strengthening the family as a cultural home. Through formal education, the young generation is educated to recognize their cultural values and local wisdom as cultural heritage. Empowering them as subjects and objects of culture is one of the practices to understand local wisdom in the context of Nias. Moreover, increasing institutional roles in preserving various cultural elements are part of the way to increase the interest of millennial to learn their existence, identity, and culture.

Synthesis of novel sulfide-based cyclic peptidomimetic analogues to solonamides
Authors: Brango-Vanegas José , Martinho Luan A , Bessa Lucinda J , Vasconcelos Andreanne G , Plácido Alexandra , Pereira Alex L , Leite José R S A , Machado Angelo H L
Published: October 2019

Eight new sulfide-based cyclic peptidomimetic analogues of solonamides A and B have been synthesized via solid-phase peptide synthesis and SN2’ reaction on a Morita–Baylis–Hillman (MBH) residue introduced at the N-terminal of a tetrapeptide. This last step takes advantage of the electrophilic feature of the MBH residue and represents a new cyclization strategy occurring. The analogues were prepared in moderate overall yields and did not show toxic effects on Staphylococcus aureus growth and were not toxic to human fibroblasts. Two of them inhibited the hemolytic activity of S. aureus, suggesting an interfering action in the bacterial quorum sensing similar to the one already reported for solonamides.
A taxonomic revision of Phyllanthus subgenus Macraea (Phyllanthaceae)
Authors: Verwijs J.I.M. , Bouman R.W. , van Welzen P.C.
Published: October 2019

Within the morphologically diverse pantropical genus Phyllanthus, many subgenera, sections and subsections are recognized. While most taxonomic revisions often focus on local floras, closely related and often resembling species are not always treated in full. Subgenus Macraea
is here revised for the first time over its whole distribution, including an identification key and descriptions of its species with distributions, ecology, uses and vernacular names. The currently acknowledged varieties of Phyllanthus distichus are rejected due to inadequate morphological
differences. Phyllanthus panayensis is synonymized with P. lancifolius. Phyllanthus alpestris has now become a variety of P. glaucophyllus because of the resemblance in morphology and distribution. The species complex around Phyllanthus virgatus remains taxonomically
difficult, but Phyllanthus virgatus var. gardnerianus and Phyllanthus virgatus var. hirtellus are here recognized on the species level as P. gardnerianus, stat nov. and P. tararae, stat & nom. nov. A new species from the Philippines,
Phyllanthus ridsdalei, is described.
Subphotospheric Turbulence as a Heating Mechanism in Gamma-Ray Bursts
Authors: Zrake Jonathan , Beloborodov Andrei M. , Lundman Christoffer
Published: October 2019

We examine the possible role of turbulence in feeding the emission of gamma-ray bursts (GRBs). Turbulence may develop in a GRB jet as the result of hydrodynamic or current-driven instabilities. The jet carries dense radiation and the turbulence cascade can be damped by Compton drag, passing kinetic fluid energy to photons through scattering. We identify two regimes of turbulence dissipation: (1) “Viscous”—the turbulence cascade is Compton-damped on a scale

greater than the photon mean free path

. Then turbulence energy is passed to photons via bulk Comptonization by smooth shear flows on scale

. (2) “Collisionless”—the cascade avoids Compton damping and extends to microscopic plasma scales much smaller than

. The collisionless dissipation energizes plasma particles, which radiate the received energy; how the dissipated power is partitioned between particles needs further investigation with kinetic simulations. We show that the dissipation regime switches from viscous to collisionless during the jet expansion, at a critical value of the jet optical depth, which depends on the amplitude of turbulence. Turbulent GRB jets are expected to emit nonthermal photospheric radiation. Our analysis also suggests revisions of turbulent Comptonization in black hole accretion disks discussed in previous works.
Modeling the Observations of GRB 180720B: from Radio to Sub-TeV Gamma-Rays

Published: October 2019

Early and late multiwavelength observations play an important role in determining the nature of the progenitor, circumburst medium, physical processes, and emitting regions associated with the spectral and temporal features of bursts. GRB 180720B is a long and powerful burst detected by a large number of observatories at multiple wavelengths that range from radio bands to sub-TeV gamma-rays. The simultaneous multiwavelength observations were presented over multiple periods of time beginning just after the trigger time and extending to more than 30 days. The temporal and spectral analysis of Fermi Large Area Telescope (LAT) observations suggests that it presents similar characteristics to other bursts detected by this instrument. Coupled with X-ray and optical observations, the standard external shock model in a homogeneous medium is favored by this analysis. The X-ray flare is consistent with the synchrotron self-Compton (SSC) model from the reverse-shock region evolving in a thin shell and previous LAT, X-ray, and optical data with the standard synchrotron forward-shock model. The best-fit parameters derived with Markov chain Monte Carlo simulations indicate that the outflow is endowed with magnetic fields and that the radio observations are in the self-absorption regime. The SSC forward-shock model with our parameters can explain the LAT photons beyond the synchrotron limit as well as the emission recently reported by the HESS Collaboration.
Stages of Reionization as Revealed by the Minkowski Functionals
Authors: Chen Zhaoting , Xu Yidong , Wang Yougang , Chen Xuelei
Published: October 2019

We study the evolution of the hydrogen ionization field during the epoch of reionization (EoR) using seminumerical simulations. By calculating the Minkowski functionals (MFs) of the 21 cm brightness temperature field, which provides a quantitative description of topology of the neutral and ionized regions, we find that the reionization process can be divided into five stages, each with different topological structures, corresponding to isolated ionized regions (“bubbles”); connected ionized regions (“ionized fibers”) that percolate through the cosmic volume; a sponge-like configuration with intertwined neutral and ionized regions after the overlap of bubbles; connected neutral regions (“neutral fibers”), when the ionized region begins to surround the remaining neutral region; and isolated neutral regions (“islands”), before the whole space is ionized except for the rare dense clumps in galaxies and minihalos and the reionization process is completed. We use the MFs and the size statistics on the ionized or neutral regions to distinguish these different stages and find the neutral fractions at which the transitions of the different stages occur. At the later stages of reionization the neutral regions are more isolated than the ionized regions; this is the motivation for the island model description of reionization. We compare the late-stage topological evolution in the island model and the bubble model, showing that in the island model the neutral fibers are more easily broken into multiple pieces owing to the ionizing background.
Thermodynamic Properties of Mirror Structures in the Magnetosheath: MMS Observations and Double-polytropic MHD Simulations
Authors: Teh Wai-Leong , Zenitani Seiji
Published: October 2019

Mirror structures are manifested as a wave train of magnetic peaks and/or dips, which are anticorrelated with plasma density. The evolution behavior of the ion temperatures perpendicular and parallel to the local magnetic field, T
⊥ and T
∥, in the magnetic peaks and dips is rare to be theoretically studied. In this paper, the thermodynamic properties of mirror structures are investigated using two-dimensional magnetohydrodynamic simulations with double-polytropic laws. Two polytropic exponents, γ
∥ and γ
⊥, are used as parameters to describe various thermodynamic conditions in the anisotropic plasma—for example, γ
∥ = 1, γ
⊥ = 1 for double-isothermal and γ
∥ = 3, γ
⊥ = 2 for double-adiabatic. Using empirical values of γ
∥ = 1.14 and γ
⊥ = 0.94 for magnetosheath plasma, the variations of T
∥ and T
⊥ in the magnetic dips and peaks observed by the Magnetospheric Multiscale Mission in the Earth’s magnetosheath can be reproduced. This consistent result cannot be achieved by use of γ
∥ = 3, γ
⊥ = 2 and γ
∥ = 0.5, γ
⊥ = 2, where the latter exponents can lead to the same mirror instability threshold as kinetic theory. In magnetic dips, T
∥ is found to be increased for γ
∥ > 1 but decreased for γ
∥ < 1, while T
⊥ is decreased for γ
⊥ > 1 but increased for γ
⊥ < 1. For magnetic peaks, the variation features of T
∥ and T
⊥ are opposite to that of the magnetic dips. It is concluded that the thermodynamic properties of mirror structures are further from double-adiabatic but closer to double-isothermal conditions.
Threshold Dissociation of the 1-ethynylpyrene Cation at Internal Energies Relevant to H i Regions
Authors: Rouillé Gaël , Steglich Mathias , Hemberger Patrick , Jäger Cornelia , Henning Thomas
Published: October 2019

Photoelectron–photoion coincidence spectroscopy has been used to measure the threshold photoelectron (TPE) spectrum of 1-ethynylpyrene and to obtain the breakdown graph describing the dissociation of the 1-ethynylpyrene cation. The TPE measurement has allowed us to improve the determination of the ionization energy of 1-ethynylpyrene at 7.391 ± 0.005 eV. Concerning the main dissociation channels, the analysis of the breakdown graph has given 3.70 ± 0.60 eV as the activation energy for the loss of one H atom and 2.98 ± 1.80 eV for the loss of a second independent H atom. The corresponding entropies of activation are affected by large errors as observed in similar studies of other polycyclic aromatic hydrocarbon (PAH) cations. Minor dissociation channels were also detected and identified as the loss of the C2H group and the loss of a C2H2 unit and/or that of an H atom plus the C2H group. The activation energies and the entropies of activation of these minor pathways could not be derived from the measurements. It is found that the cation of 1-ethynylpyrene behaves like that of pyrene and is consequently more photostable than that of 1-methylpyrene. We conclude that photodissociation is not the leading cause of the low abundance, if not the absence, of ethynyl-substituted PAH species in the interstellar medium.
The Formation of Subdwarf A-type Stars
Authors: Yu Jinlong , Li Zhenwei , Zhu Chunhua , Wang Zhaojun , Liu Helei , Guo Sufen , Han Zhanwen , Chen Xuefei , Lü Guoliang
Published: October 2019

Subdwarf A-type stars (sdAs) are objects that have hydrogen-rich spectra with surface gravity similar to that of hot subdwarf stars but effective temperature below the zero-age horizontal branch. They are considered to be metal-poor main-sequence (MS) stars or extremely low-mass white dwarfs (ELM WDs). In this work, using the stellar evolution code Modules for Experiments in Stellar Astrophysics, we investigate the sdAs formed both by the evolution of (pre-)ELM WDs in double-degenerate systems and metal-poor MS stars with single evolution models. We find that both of the evolutionary tracks of ELM WDs and metal-poor MS stars can explain the observation properties of sdAs. However, the proportions between these two populations are uncertain. In this work, we adopt the method of binary population synthesis of both ELM WDs in the disk and metal-poor MS stars in the halo to obtain their populations at different stellar population ages and calculate their proportions. We find that the proportion of metal-poor MS stars to sdAs for a stellar population of 10 Gyr is ∼98.5%, which is consistent with the conclusion that most sdAs (>95%) are metal-poor MS stars. And the proportion of ELM WDs (metal-poor MS stars) to sdAs increases (decreases) from 0.1% (99.9%) to 20% (80%) with stellar population ages from 5 to 13.7 Gyr.
Species delimitation of crab-eating frogs (Fejervarya cancrivora complex) clarifies taxonomy and geographic distributions in mainland Southeast Asia
Authors: Yodthong Siriporn , Stuart Bryan L. , Aowphol Anchalee
Published: October 2019

The taxonomy and geographic distributions of species of crab-eating frogs (Fejervarya cancrivoracomplex) in mainland Southeast Asia have been highly uncertain. Three taxonomic names are used in recent literature (F. cancrivora,F. raja, andF. moodiei) but the applications of these names to localities has been inconsistent, especially owing to the lack of available molecular data forF. raja. Morphometric and mitochondrial DNA variation was examined in these frogs, including name-bearing types and topotypes of all three species. Findings corroborate evidence for the existence of two species in coastal mainland Southeast Asia, withF. moodieihaving a wide geographic distribution andF. cancrivorasensu stricto occurring only in extreme southern Thailand and peninsular Malaysia.Fejervarya rajais shown to be only a large-bodied population ofF. cancrivorasensu stricto and is synonymized with that species.

Le « je n’en veux rien savoir » de Lacan
Authors: Porge Erik
Published: October 2019

On ne peut qu’être surpris de l’affirmation de Lacan qui ouvre Le Séminaire Encore et selon laquelle ce qui a constitué son cheminement était « de l’ordre du “je n’en veux rien savoir” ». Affirmation d’autant plus surprenante qu’il la mesure au ne rien vouloir savoir propre à l’analysant et que l’écart serait une raison d’interrompre l’analyse. Le texte initie un commentaire de l’assertion de Lacan, pour autant qu’elle concerne chaque analysant devenant analyste.

Donald Trump et les « Cinq de la Rust Belt »
Authors: High Steven , Mak Ariane
Published: October 2019

Partout dans le monde désindustrialisé, le désespoir silencieux durant des décennies a laissé place à une révolte ouverte à l’encontre des élites politiques et culturelles. Aux États-Unis du moins, un débat agite les progressistes – définis au sens large comme les «  liberal centrists  » et les «  social democrats  » – sur les causes profondes de ce phénomène. Cet article propose de répondre à ces questions en mobilisant le champ interdisciplinaire des deindustrialization studies et en examinant ce que celui-ci peut nous apprendre des racines historiques et des causes sous-jacentes de l’ascension de Donald Trump. Les leçons politiques que nous serons amenés à tirer de l’histoire récente constituent un enjeu de taille.
Perceptions of Mobile Technology for Heart Failure Education and Self-Management Among Middle-Aged and Older Adults
Authors: Tarte Valerie P. , Amirehsani Karen A.
Published: October 2019

Mobile technology is a promising educational platform for chronic disease management. Patients with heart failure (HF) have high rates of hospitalization and complications. The goal of the current cross-sectional study was to determine if middle-aged and older adults were using or willing to use technology for HF education and self-management. A convenience sample of 37 patients with HF were recruited from an outpatient HF clinic. Participants were asked to complete a 23-item paper survey. Male participants comprised 59.5% of the sample and 54.1% of the sample reported being age ≥65. Most participants (60%) described using text messaging and Facebook

, 78.3% reported believing technology could help with HF management, and 70.3% of participants indicated willingness to use technology. Findings indicate that incorporating mobile technology into HF education and self-management is of interest to middle-aged and older adults. These findings have important implications for designing HF patient education programs. [

Examining the Impact of Board-Certified Registered Nurses in Skilled Nursing Facilities Using National and State Quality and Clinical Indicators
Authors: Keeler Heidi , Baier Rosa R. , Kosar Cyrus , Culross Beth , Cramer Mary E.
Published: October 2019

A convenience sample of skilled nursing facilities was selected from a sample of graduates of an online training program for RNs who subsequently achieved board certification in gerontological nursing (RN-BC). Facilities that employed one or more RN-BC were pair-matched using 11 organizational characteristics with facilities that did not employ a RN-BC. Facility data were collected at two time points, and differences between time points and between facility type (RN-BC versus non-RN-BC) were analyzed. Findings showed that there were no statistically significant differences between RN-BC and non-RN-BC facilities with respect to quality ratings and nurse sensitive clinical indicators (e.g., restraint use, urinary tract infections, falls, antipsychotic medication use) between the two time periods; however, in the second time period, RN-BC facilities showed greater improvement versus non-RN-BC facilities in seven of nine outcomes, achieving significance in Overall (4.10 vs. 3.55,
p
< 0.01) and Survey (3.48 vs. 2.86,
p
< 0.01) 5-Star ratings. [

Une interprétation fonctionnelle des habitats rubanés
Authors: Berrio Laura , Blouet Vincent , Wiethold Julian
Published: October 2019

L’étude de la répartition pondérée des microvestiges et des macrorestes végétaux issus du remplissage du négatif des poteaux du bâtiment M5 de Marainville permet de préciser l’architecture et la fonction des différentes parties de cette habitation. Des occurrences similaires sont observables, avec quelques variantes, sur les autres bâtiments de Marainville, et la méthode met en évidence une évolution chronologique intra-site. Cet article montre l’intérêt de la généralisation de ce type d’études et de la constitution de séries significatives qui devraient permettre de mieux cerner l’évolution et les éventuels particularismes régionaux des habitats rubanés. Le développement de cette méthodologie nécessiterait ainsi la mise en place d’un protocole normalisé pour le prélèvement et le tamisage du remplissage des poteaux.
World of the Dye

Published: October 2019

The textile sector is 14% of total industrial production in India and contributes to about 4% of the gross domestic product and earns about 27% of India's total foreign exchange. Worldwide, up to 10,000 dyes are available and their annual production is above 7×105 metric tons, which are being used not only in textile sector but also applied in paper, food, and pharmaceutical industries. Textile industries in India have been consuming more than 100 L of water to process 1 kg of textiles and have contributed heavily in polluting surface and ground water resources in many regions of the country. The toxic and carcinogenic effect of untreated textile effluent is well understood. The decolorization and detoxification of industrial dye effluents is the most important aspect and is a major concern to meet environmental regulations. This chapter presents a review of literature on the significance of bioremediation technologies over other physicochemical methods for efficient removal of textile dyes from industrial waste effluents to improve the fragile ecosystems in different regions of the world.
Impact of Synthetic Dyes on Human Health and Environment
Authors: Srivastava Ruchi , Sofi Irfan Rashid
Published: October 2019

Colour is the most important part to make any fabric attractive, but its use for dying has become a major environmental hazard. Colloidal particles present with color increases the turbidity, gives bad appearance, foul odour, and obstructs the penetration of sunlight into water bodies required for the photosynthesis process, which interferes with the oxygen flow mechanism and hence marine life. So, it is essential to remove such pollutants from the waste water before its final disposal into water bodies. Photocatalysis is one of the advance oxidation processes, mainly carried out in the presence of light and suitable photocatalytic materials for the degradation of dyes. This chapter outlines the background of dye chemistry, the application areas, and the impact of dyeing effluents in the environment and on living beings.
Enabling Policies for Advancing Sustainability of Electricity Access Programs
Authors: Bhattacharyya Subhes C. , Palit Debajit
Published: October 2019

As 1.3 billion people lack access to electricity globally, the challenge of ensuring universal electricity access in accordance with the Sustainable Energy for All initiative remains herculean. This chapter maps policy linkages, identifies the gaps in policies and recommends options for developing the enabling environment. The chapter suggests that the policy environment governing electricity access at present is weak and that improvements are required to deliver a sustainable outcome. Although grid extension remains the preferred mode of electrification in many countries, it is not the least-cost option in remote areas where decentralized off-grid solutions may be required. Successful promotion of off-grid solutions would require a clear regulatory environment, a non-discriminatory support mechanism for various stages of a project, financing options, policy co-ordination and linkage with other economic activities for rural development. The chapter concludes that capacity remains weak and non-transparent policy lobbying can distort the development of an enabling environment.
Efficient Control Strategies to Optimize Electricity Cost and Consumer Satisfaction
Authors: Minhas Daud Mustafa , Hussain Sajjad
Published: October 2019

Increasing consumer demand of electricity is difficult for the conventional power system network to handle, regarding both cost and infrastructure. Instead of expanding the expensive infrastructure, power engineers are now focusing on improving efficiencies and effectiveness of existing power networks. This chapter specifically focuses on low cost electricity supply, by introducing the novel concept of digital energy management system in hybrid AC/DC micro-grid. It is assumed that grid is partially powered by time varying renewable resources. The concept of minimizing time average electricity cost is introduced by efficient utilization of these renewable resources and by making the load demands more flexible to operate while taking converter losses into account. Real time pricing model is introduced to elaborate the advantage of time-of-use pricing. Control decisions will be achieved by proposing a load scheduling and hybrid switching (LSHS) algorithm. This algorithm will be capable of supplying low cost electricity while serving the load demands under specific delay bounds.

Authors: Sukholthaman Pitchayanin , Shirahada Kunio
Published: October 2019

Knowledge management (KM) is a key factor to increase effectiveness of management system. There have been researches of KM on many environmental services. Unfortunately, only a few researches have focused on sustainable service for Municipal Solid Waste (MSW). There are evidences of ineffective waste management causing socio-economic and environmental problems, especially in urban areas of developing countries. Humans live in service economy and knowledge society. Waste management is one of the most important public services that all residents should receive while knowledge is needed to make service run smoothly and sustainably. This paper combines concepts of sustainable service and KM to clarify the importance and how these concepts have impacts on societal well-being. Literature reviews and questionnaire surveys are main analysis methods of this paper. Sustainable service with KM roles will be described and co-created values are identified.
