The Correlation of Outflow Kinematics with Star Formation Rate. VI. Gas Outflows in AGNs
Authors: Woo Jong-Hak , Son Donghoon , Rakshit Suvendu 
Published: September 2020

Abstract
We investigate the connection between ionized gas outflows and star formation activity using a large sample of type 1 and 2 active galactic nuclei (AGNs) with far-infrared detections or star formation rate (SFR) estimates. The strength of ionized gas outflows, measured by the velocity dispersion and velocity shift of the [O iii] emission line, clearly shows a correlation with SFR. The connection between specific star formation rate (sSFR) and [O iii] gas velocity dispersion indicates that AGNs with stronger outflows are hosted by galaxies with higher SFR. Compared with star-forming galaxies in the main sequence, both type 1 and type 2 AGNs show sSFRs similar to that of non-AGN galaxies, indicating no instantaneous AGN feedback, while sSFR is higher (lower) for AGNs with stronger (weaker) outflows than that of main-sequence galaxies. These results are consistent with a delayed AGN feedback scenario. However, it is also possible that a decease/increase of gas fraction may cause the correlation without AGN feedback.
Termination Shock as a Source of Unusual Solar Radio Bursts
Authors: Fomichev Valery , Chernov Gennady 
Published: September 2020

Abstract
Using centimeter-wave and decimeter-wave solar radio spectral observations of the flares of 2003 November 18 and 2004 September 12, we have discussed two type-II-like bursts at the meter waves. The radio bursts show that the ordinary frequency drift from high to low frequencies slows down and stops, and a frequency drift from low to high frequencies appears. An analysis of all data on the corresponding flares provides evidence of the formation of quasi-standing fast-mode shocks (termination shocks, TSs). TSs are able to generate energetic electrons, responsible for the appearance of new sources of hard X-ray radiation and generation of fast radio bursts (spikes), fibers, and zebra structures. The sources of the radio emission bands with the unusual frequency drift are situated above the top of the post-flare loops (lower TS) or are connected with the erupting prominence or coronal mass ejection (upper TS). Estimations of the critical Mach numbers for the ordinary plasma parameters in the solar flares give the values M
cr = 1.1–1.3 easily realized in the flare events. The conditions necessary for the generation of unusual radio bursts are likely to occur in the helmet-shaped magnetic structures in the solar corona.
The Role of Peak Temperatures in Solar X-Ray Flare Associations with CME Speeds and Widths and in Flare Size Distributions
Authors: Kahler S. W. , Ling A. G. 
Published: September 2020

Abstract
Recently, we reported that solar X-ray flares with relatively low peak (0.05–0.3 nm)/(0.1–0.8 nm) ratios R, a proxy for peak flare temperature T, were preferentially associated not only with solar energetic (E > 10 MeV) particle (SEP) events, but also with fast (V
cme ≥ 1000 km s−1) coronal mass ejections (CMEs) that produce the SEP events. Flares associated with a characteristic CME speed V
cme range from small and cool to large and hot, and cooler X-ray flares were preferentially associated with broader CME widths. Here we increase the list of analyzed Geostationary Operational Environmental Satellite flares from the previous 450 to 588 and validate the earlier results with flare peak X-ray temperatures T from the TEBBS (Temperature and Emission measure-based Background Subtraction) method catalog. Power-law size distributions of flare peak fluxes F
p are increasingly steeper for X-ray flares with (1) fast (V
cme ≥ 1000 km s−1); (2) slow (V
cme < 1000 km s−1); and (3) no CMEs; in each case flares of larger F
p are characteristically hotter. The power-law size distribution of SEP event peak intensities I
p is flatter than any of the X-ray F
p distributions or a distribution formed from the product of the steep SEP I
p dependence on V
cme and the V
cme number distributions.

Abstract
We present photometry and spectroscopy of four hydrogen-poor luminous supernovae discovered during the 2-month long science commissioning and early operations of the Zwicky Transient Facility (ZTF) survey. Three of these objects, SN 2018bym (ZTF18aapgrxo), SN 2018avk (ZTF18aaisyyp), and SN 2018bgv (ZTF18aavrmcg), resemble typical SLSN-I spectroscopically, while SN 2018don (ZTF18aajqcue) may be an object similar to SN 2007bi experiencing considerable host galaxy reddening, or an intrinsically long-lived, luminous, and red SN Ic. We analyze the light curves, spectra, and host galaxy properties of these four objects and put them in context of the population of SLSN-I. SN 2018bgv stands out as the fastest-rising SLSN-I observed to date, with a rest-frame g-band rise time of just 10 days from explosion to peak—if it is powered by magnetar spin-down, the implied ejecta mass is only ≃1 M
⊙. SN 2018don also displays unusual properties—in addition to its red colors and comparatively massive host galaxy, the light curve undergoes some of the strongest light-curve undulations postpeak seen in an SLSN-I, which we speculate may be due to interaction with circumstellar material. We discuss the promises and challenges of finding SLSNe in large-scale surveys like ZTF given the observed diversity in the population.
Probing Dark Low-mass Halos and Primordial Black Holes with Frequency-dependent Gravitational Lensing Dispersions of Gravitational Waves
Authors: Oguri Masamune , Takahashi Ryuichi 
Published: September 2020

Abstract
We explore the possibility of using amplitude and phase fluctuations of gravitational waves due to gravitational lensing as a probe of the small-scale matter power spectrum. The direct measurement of the small-scale matter power spectrum is made possible by making use of the frequency dependence of such gravitational lensing dispersions originating from the wave optics nature of the propagation of gravitational waves. We first study the small-scale behavior of the matter power spectrum in detail taking the so-called halo model approach, including the effects of baryons and subhalos. We find that the matter power spectrum at the wavenumber k ∼ 106
hMpc−1 is mainly determined by the abundance of dark low-mass halos with mass

and is relatively insensitive to baryonic effects. The matter power spectrum at this wavenumber is probed by gravitational lensing dispersions of gravitational waves at frequencies of f ∼ 0.1–1 Hz with predicted signals of

. We also find that primordial black holes (PBHs) with M
PBH ≳ 0.1 M
⊙ can significantly enhance the matter power spectrum at k ≳ 105
hMpc−1 due to both the enhanced halo formation and the shot noise from PBHs. We find that gravitational lensing dispersions at f ∼ 10–100 Hz are particularly sensitive to PBHs and can be enhanced by more than an order of magnitude depending on the mass and abundance of PBHs.
Laisser le pétrole sous terre
Authors: Le Quang Matthieu 
Published: September 2020

Laisser le pétrole sous terre. Cette revendication de nombreuses organisations écologistes dans le monde pour lutter contre les émissions de gaz à effet de serre a été reprise par le gouvernement équatorien en mai 2007 pour en faire une des politiques publiques les plus innovantes contre le réchauffement climatique. Cette politique était complexe à mettre en œuvre, d’autant plus dans un pays dont l’économie dépend de l’exploitation et de l’exportation du pétrole, mais aussi à cause du mode de financement qui la livrait à la bonne volonté des autres États, principalement du Nord.
Lettre aux Gilets jaunes
Authors: Rozenholc Anita , Dessendier Emmanuel 
Published: September 2020

Repartant de l’analyse faite dans notre précédent numéro du mouvement des Gilets jaunes 1 , Anita Rozenholc y ajoute une clé de lecture « spinoziste ». L’autrice fait le pari que celle-ci, en ancrant la réflexion dans le vécu des Gilets jaunes, est de nature à emmener le plus grand nombre sur les voies de l’écologie politique, celles que dessinent Murray Bookchin, André Gorz, Félix Guattari ou encore Ivan Illich.
Partir des besoins à partir d’André Gorz
Authors: Gianinazzi Willy 
Published: September 2020

Le livre de Razmig Keucheyan sur les « besoins artificiels » et sur la façon de s’en passer mérite plus qu’une recension : il invite à la discussion et a toute sa place dans cette rubrique dédiée aux études « gorziennes ». En partant des travaux d’André Gorz et d’Ágnes Heller qui ont pour socle les prémisses théoriques de Karl Marx, il fournit un cadre détaillé des formes d’aliénation, mais aussi des nouveaux besoins et revendications que suscite la croissance, c’est-à-dire la mainmise du capitalisme sur la consommation .
Le deuil des corps disparus dans la communauté afro-colombienne au Nord Chocó
Authors: Castillo Grandas Angela Maria 
Published: September 2020

Ce travail de recherche qualitative exploratoire, réalisé dans le cadre du diplôme universitaire « Médecines et Soins transculturels » de l’Université de Bordeaux, a pour objectif d’investiguer la façon dont les communautés afro-colombiennes du Chocó réalisent des rituels de mort lorsqu’il n’y a pas de corps. Nous avons mené des entretiens semi-structurés avec cinq femmes afro-colombiennes. Les thèmes suivants ressortent particulièrement des entretiens : la situation au Chocó après l’accord de paix avec les FARC ; les massacres, la disparition et les croyances sur la mort ; la bonne mort où comment faire son deuil sans avoir vu le corps ; la transformation du sens des rites mortuaires en raison de la guerre. Nous constatons que la guerre modifie le travail de deuil et l’essence de la personne.
La transition énergétique de la Chine est-elle soutenable ? Une analyse centrée sur l’absorption du surplus de travail
Authors: Berthaud Pierre , Fontana Yann 
Published: September 2020

La transition énergétique chinoise s'opère depuis 2010 sur un fond de transition économique. La relation entre ces deux processus est appréhendée ici par un cadre d’analyse de changement structurel à la Lewis. Le mode de développement mis en œuvre par la Chine jusqu’à la fin des années 2000 a certes été très impactant pour l’environnement, mais il a aussi mis en place des conditions favorables à une transition énergétique ambitieuse, en résorbant le surplus de travail agricole. Cette absorption constitue une condition nécessaire quoique non suffisante à la réussite du processus de transition.
Pharmaceutical supply chain transformation through application of the Lean principle: A literature review
Authors: Argiyantari Berty , Simatupang Togar M , Hasan Basri Mursyid 
Published: September 2020

Purpose: This study aims to review the previous literature on the topic contained in the title in order to identify gaps in the existing research relating to lean supply chain-related issues within the pharmaceutical industry since limited attention has been devoted to this sector. Design/methodology/approach: This study presents a systematic literature review that proposes an analysis and classification of the previous literature as falling within one of four categories, namely; the supply chain area, research approach, research objective, and lean supply chain elements.Findings: The results of this study indicate that most attention was focused on manufacturing, while upstream suppliers, downstream activities and the entire supply chain process have received comparatively scant consideration. Similarly, the issues of information technology management, supplier management, customer relations, and logistics management as well as practitioner involvement represent inadequately developed topics. Future research should address these omissions, in addition to the integration of quality compliance and digital innovation as they relate to pharma 4.0.Practical implications: This article serves as a guide to acquiring sufficient knowledge of the pharmaceutical supply chain prior to implementing lean supply chain management. Moreover, it is anticipated that the research it contains will contribute to eradicating the knowledge gap by expanding the existing limited body of literature on the adoption of lean approach in the PSC.Originality/value: This study is one of a limited number of literature analyses potentially helpful in developing a roadmap of lean principle application to the pharmaceutical supply chain
Assistive Mobile Application for Visually Impaired People
Authors: Nayak Sriraksha , C B Chandrakala 
Published: September 2020

According to the World Health Organization estimation, globally the number of people with some visual impairment is estimated to be 285 million, of whom 39 million are blind. The inability to use features such as sending and reading of email, schedule management, pathfinding or outdoor navigation, and reading SMS is a disadvantage for blind people in many professional and educational situations. Speech or text analysis can help improve support for visually-impaired people. Users can speak a command to perform a task. The spoken command will be interpreted by the Speech Recognition Engine (SRE) and can be converted into text or perform suitable actions. In this paper, an application that allows schedule management, emailing, and SMS reading completely based on voice command is proposed, implemented, and validated. The System hopes to provide blind people to simply speak the desired functionality and be guided thereby the system’s audio instructions. The proposed and designed app is implemented to support three languages which are English, Hindi, and Kannada.
Dynamic Roles for IL-2–STAT5 Signaling in Effector and Regulatory CD4+ T Cell Populations
Authors: Jones Devin M. , Read Kaitlin A. , Oestreich Kenneth J. 
Published: September 2020

Abstract
CD4+ Th cells are responsible for orchestrating diverse, pathogen-specific immune responses through their differentiation into a number of subsets, including TH1, TH2, TH9, T follicular helper, T follicular regulatory, and regulatory T cells. The differentiation of each subset is guided by distinct regulatory requirements, including those derived from extracellular cytokine signals. IL-2 has emerged as a critical immunomodulatory cytokine that both positively and negatively affects the differentiation of individual Th cell subsets. IL-2 signals are propagated, in part, via activation of STAT5, which functions as a key regulator of CD4+ T cell gene programs. In this review, we discuss current understanding of the mechanisms that allow IL-2–STAT5 signaling to exert divergent effects across CD4+ T cell subsets and highlight specific roles for this pathway in the regulation of individual Th cell differentiation programs.

Los eventos cardiovasculares representan la mayor complicación de la diabetes. La evidencia sugiere que la metformina mejora los resultados cardiovasculares en pacientes con diabetes, especialmente en el United Kingdom Prospective Diabetes Study (UKPDS) y otros estudios posteriores, por distintos mecanismos.Hay pocos estudios de seguridad cardiovascular para sulfonilureas aunque no tendrían un perfil seguro a este nivel. La gliclazida parece ser la de mejor performance de las drogas de este grupo. Algo similar ocurre con las meglitinidas, para las cuales los datos indican que no aumentarían el riesgo pero tampoco mejorarían la incidencia de eventos cardiovasculares.Las tiazolidinodionas son las drogas más cuestionadas, aunque los estudios y metaanálisis son contradictorios no habría dudas que aumentan el riesgo de insuficiencia cardíaca. Los inhibidores de la DPPIV mostraron resultados neutros a excepción de saxagliptina que aumentaría el riesgo de internación por insuficiencia cardiaca.Existen datos convincentes que los inhibidores de los receptores SGLT-2 a nivel renal y los análogos del GLP-1 intestinal tienen efectos positivos a nivel cardiovascular, con algunas diferencias entre los integrantes de esta familia.En cuanto a las insulinas, los estudios sugieren que tanto los análogos lentos como rápidos tendrían un mejor perfil cardiovascular, ligado principalmente a la menor incidencia de hipoglucemias severas, que insulina NPH y regular respectivamente.

Published: September 2020

A pesquisa qualitativa que balizou a produção desse artigo objetivou analisar os artigos publicados no GDP EA no contexto escolar do ano de 2017. A análise de conteúdo foi utilizada para categorização dos seguintes significados emergentes da análise: partícipes da pesquisa: professores e estudantes da escola básica são os principais investigados. Investigações englobando toda comunidade escolar e local ainda são incipientes; natureza e tipo da pesquisa: a abordagem qualitativa é predominante; coleta de dados: a utilização de multimétodos de análise aparece em minoria; e análise de dados: na sua maioria a metodologia não indica o método de análise. A discussão sobre vias de inserção da EA na escola é ainda um aspecto bastante presente e com predomínio da macrotendência pedagógica crítica.
horta escolar como caminho para a agroecologia escolar
Authors: Riguetto Nunes Letícia , Rotatori Camila , Cosenza Angélica 
Published: September 2020

O presente artigo surge a partir de entrecruzamentos de dados de um projeto de iniciação científica, desenvolvido entre os anos de 2016 e 2019, e de uma dissertação de mestrado defendida em 2019. O artigo objetiva discutir dados sobre estruturas físicas e pedagógicas de hortas de escolas públicas de uma cidade no estado de Minas Gerais, além de discutir suas implicações à agroecologia e à educação ambiental a partir da problematização de discursos docentes. Por meio da imersão nas escolas mapeadas e de um curso de formação, realizamos entrevistas semi-estruturadas com os/as responsáveis pelas hortas escolares e as analisamos, a partir dos pressupostos da Análise Crítica do Discurso. As práticas pedagógicas relacionadas à horta escolar se relacionam à uma Educação Ambiental que pouco discute temáticas sociocríticas, entretanto destacamos o potencial contra-hegemônico do trabalho pedagógico, já que as professoras entrevistadas enunciam a natureza como direito de ser e existir ao trabalhar e discutir conteúdos que permeiam seu cotidiano, possibilitando estreitar laços entre comunidade e escola, assim como a ressignificação da relação entre sociedade, natureza e alimento.

An Analysis of an Organization’s Budgetary Control System and its Link with Performance Management and Decision Making
Authors: Choge Grace 
Published: September 2020

Purpose: the purpose of this study was to analyze the impact of an organization’s budgetary control system on performance management and decision making.Methodology: The study population consisted of top management and middle level management of SDV Transami in Kenya. The choice of the top management and middle level management was because budgetary control is mostly influenced by these two management levels. The study sample was 46 departmental heads. A census methodology was taken since the population was small enough. Primary and secondary data were collected. Secondary data sources were used to supplement primary data to enable the researcher get in-depth information concerning the topic of research. The information was mined from scholarly works on budgetary control found in text books, magazines, management reports, operations guidelines and previous researches. Statistical Package for Social Sciences (SPSS) was used to generate the descriptive statistics and also to generate inferential results. Regression and correlation analysis was used to demonstrate the relationship between the variables. The results were presented in form of charts, graphs and tables.Results: Results show that the managers rely on budgets to make decisions and further went to indicate that budgetary control was highly important in making managerial decisions. Budgetary control also influenced decision making in the organization in regards to decision on performance indicators. Trend analysis reveals that budgetary control affects decision making positively. Correlation and regression results revealed that there is a positive and significant relationship between budgetary control and decision making.Unique contribution to theory, practice and policy: Since a positive and significant relationship was found to exist between budgetary control and performance management and decision making, it is recommended that budgetary control should be upheld. In addition, there should be involvement of staff in coming up with budgets. Furthermore, the organization should ensure that it continues with the practice of involving top management in coming up with budgets.
