Pelecehan seksual dapat berupa komentar verbal, gerakan tubuh atau kontak fisik yang bersifatseksual yang dilakukan seseorang dengan sengaja, dan tidak dikehendaki atau tidak diharapkan olehkorban. Sedangkan Pelecehan di ruang publik diambil dari kata “street harassment” yang diartikanpelecehan di jalan atau ruang publik. Maraknya kasus pelecehan seksual yang terjadi di ruang publikdan banyak diberitakan di media massa dan media sosial, membuat masyarakat khususnya parawanita menyadari tentang bahayanya pelecehan seksual. Mereka memahami bahwa pelecehanseksual dapat terjadi dalam berbagai bentuk, kapan saja dan dimana saja. Para korban yang pernahmenjadi korban pelecehan seksual di ruang publik kini lebih waspada dan berhati-hati ketikaberaktivitas di luar rumah dan ketika berhadapan dengan orang asing. Mereka menjadi lebih pekaakan hal-hal ganjil yang terjadi pada atau di sekitar mereka. Pelecehan seksual di ruang publik dapatditekan dengan memberikan pendidikan seks dini kepada anak-anak di bawah umur dan penerapanhukum yang tegas pada pelaku pelecehan serta adanya pemikiran terbuka dari masyarakat terhadapkasus pelecehan seksual untuk membantu pemulihan trauma korban.
Mitos Dalam Film Si Kabayan Berjudul "TARUHAN" Karya Didi Petet
Authors: Ridwan Iwan Muhammad
Published: August 2020

The research entitled "Myths in the Si Kabayan Film Titled Didi Petet's Betting" aims to uncover a number of myths that actually occur in Sundanese society and analyze them about Roland Barthes's semiotic approach to the meaning of denotation and connotation. In the film Si Kabayan: Bet there are a number of myths which are a blend of myths that have lived in society and myths that were created by Si Kabayan's ingenuity. Si Kabayan's figure is always identified with the character of silly, lazy, but a lot of sense that can often defeat the antagonist he faces. Likewise, this film was produced in 1991. The Kabayan can fool the characters who become antagonists for himself with a number of myths he made. Even so, interpreting the myths that are found in the film Si Kabayan: Bets are needed interpretations from the people who live in Si Kabayan's living environment, because a number of these myths are mostly special myths that are rarely heard in real life. Some myths can also be broken by Si Kabayan himself.

Published: August 2020

The article presents the results of a study on the cerebral hemodynamics of residents of the Volgograd region (165 respondents: 18–35 years old; 50–55 years; 56–60 years and over 61 years), making it possible to identify the parameters that are the most informative for assessing of blood supply disorders of the brain.

Objective: to study the age features of cerebral blood circulation connected with breath phases.

Evaluation of the functional state of the cerebral hemodynamics was carried out on the basis of comprehensive studies of blood supply to the brain (rest and against the background of respiratory test) using the method of reoencephalography.

The reoencephalographic examination was performed in 4 leads (FM, OM left hemisphere; FM, OM right hemisphere). Indicators were registered: integral index of pulse filling, amplitude-frequency index, rheographic index, time of propagation of the rheographic wave, average vessel filling rate, venous outflow, dicrotic index, diastolic index.

Decrease in total pulse blood filling of the brain at respondents of 50–55 years is revealed. In the dynamics of respiratory test myogenic reactions of vasoconstriction of resistive arteries of the brain in people of older age (50–55 years and older) are slightly expressed. The limit of vasoconstrictor reactions caused by the aging of the body is the cause of deterioration of the conditions of regional blood outflow.

The inconsistency of the ratio of regional blood flow to its outflow is a marker of the reduction of adaptive reactions of the circulatory system of people over 50 years of age with an increase in venous pressure in the upper vena cava system.

The information value, efficiency and safety of the reographic study at rest and against the background of respiratory test allows it to be recommended for inclusion in the plan of dispensary observations, especially those over 50 years of age.

La acumulación de plomo en el ambiente es una causa de problemas de salud en humanos. La dosis letal media reportada en mg/kg para Pb, Pb (NO3)2 y PbO es de 400, 2250 y 2000, respectivamente. Debido a la alta toxicidad del plomo metálico con respecto al nitrato de plomo se ha desarrollado una metodología para transformar el plomo residual a nitrato de plomo, cuya toxicidad es cinco veces menor que el plomo metálico. Por otra parte, el nitrato de plomo puede ser precursor para la síntesis de materiales con potencial aplicación industrial. La síntesis del Pb (NO3)2 se realiza mezclando el plomo metálico residual y ácido nítrico 15.7 molar en una proporción de reactivos [1:4]. Posteriormente, la mezcla se somete a agitación magnética hasta disolver el plomo y formar un precipitado blanco, se seca a 110 °C durante 1 h obteniendo un rendimiento experimental del 99 %. El material sintetizado se caracteriza por difracción de rayos–X, microscopía electrónica de barrido y espectroscopia por dispersión de energía. Así mismo, esta metodología tiene un impacto favorable en los ecosistemas, ya que la contaminación por plomo se verá disminuida.
Recovered Media in Argentina: An Inclusive Digital Movement
Authors: Escudero Carolina
Published: August 2020

The basis for this paper is the recovered factories movement, which began in Argentina in 2001, and which has grown over the past decade to include media companies, transcending digital inequalities and turning them into opportunities for journalists and media outlets. Just like elsewhere, the situation for journalists in Argentina is precarious, with technological barriers increasing digital inequalities and a lack of respect for workers’ rights, particularly when political processes such as changes in government lead to new economic plans and market instability. This situation of great uncertainty for the press has given rise to a movement on the increase in recent years, known as “recuperated or recovered media” or “workers’ co-ops”. Between 2016 and 2017, at least six media outlets were recuperated by their workers after being closed down or abandoned by their owners, including La Nueva Mañana, in Córdoba; El Ciudadano of Rosario; La Portada, of Esquel; and the Tiempo Argentino newspaper and online news site Infonews, both based in Buenos Aires. Tiempo Argentino is the only national newspaper supported by its readership, contributing 70% of revenue, which has made it one of the few independent voices of dissent in Argentina at a time of high media concentration and domination. The Tiempo Argentino newspaper was one of the winners of the first Latin American Google News Initiative (GNI), illustrating how this movement has transcended politico-social difficulties and transformed digital inequalities into digital inclusion/opportunities. The GNI is an initiative that fosters innovation aiming to improve the sustainability of journalism in a digital era by developing open source software, so as to improve user experience on the Web and optimize internal management procedures for members. Once the software is finalized, the co-op will develop a prototype to be made available to other self-managed media outlets in order to strengthen their membership model. Hence, this exploratory study seeks to analyze the phenomenon of the recovered media in Argentina, focusing on the experience of Tiempo Argentino as the newspaper and its workers face a new digital challenge. At the end of 2001, Argentina’s political and economic crisis was the main theme in world news coverage. At this period and in response to the economic crisis, workers seized control of many abandoned factories. The rise of these “recuperated/recovered businesses”
The Gaia–Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age
Authors: Berger Travis A. , Huber Daniel , Gaidos Eric , van Saders Jennifer L. , Weiss Lauren M.
Published: August 2020

Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the Gaia Data Release 2 by Berger et al., we recompute Kepler planet radii and incident fluxes and investigate their distributions with stellar mass and age. We measure the stellar mass dependence of the planet radius valley to be

/

, consistent with the slope predicted by a planet mass dependence on stellar mass (0.24–0.35) and core-powered mass loss (0.33). We also find the first evidence of a stellar age dependence of the planet populations straddling the radius valley. Specifically, we determine that the fraction of super-Earths (1–1.8

) to sub-Neptunes (1.8–3.5

) increases from 0.61 ± 0.09 at young ages (<1 Gyr) to 1.00 ± 0.10 at old ages (>1 Gyr), consistent with the prediction by core-powered mass loss that the mechanism shaping the radius valley operates over Gyr timescales. Additionally, we find a tentative decrease in the radii of relatively cool (F
p < 150

) sub-Neptunes over Gyr timescales, which suggests that these planets may possess H/He envelopes instead of higher mean molecular weight atmospheres. We confirm the existence of planets within the hot sub-Neptunian “desert” (2.2 R
⊕ < R

, F
p > 650

) and show that these planets are preferentially orbiting more evolved stars compared to other planets at similar incident fluxes. In addition, we identify candidates for cool (F
p < 20

) inflated Jupiters, present a revised list of habitable zone candidates, and find that the ages of single and multiple transiting planet systems are statistically indistinguishable.
Hidden Worlds: Dynamical Architecture Predictions of Undetected Planets in Multi-planet Systems and Applications to TESS Systems
Authors: Dietrich Jeremy , Apai Dániel
Published: August 2020

Multi-planet systems produce a wealth of information for exoplanet science, but our understanding of planetary architectures is incomplete. Probing these systems further will provide insight into orbital architectures and formation pathways. Here we present a model to predict previously undetected planets in these systems via population statistics. The model considers both transiting and non-transiting planets, and can test the addition of more than one planet. Our tests show the model’s orbital period predictions are robust to perturbations in system architectures on the order of a few percent, much larger than current uncertainties. Applying it to the multi-planet systems from the Transiting Exoplanet Survey Satellite (TESS) provides a prioritized list of targets, based on predicted transit depth and probability, for archival searches and for guiding ground-based follow-up observations hunting for hidden planets.
Modeling the Chronologies and Size Distributions of Ceres and Vesta Craters
Authors: Roig F. , Nesvorný D.
Published: August 2020

We infer the crater chronologies of Ceres and Vesta from a self-consistent dynamical model of asteroid impactors. The model accounts for planetary migration/instability early in the history of our solar system and tracks asteroid orbits over 4.56 Gyr. It is calibrated on the current population of the asteroid belt. The model provides the number of asteroid impacts on different worlds at any time throughout the solar system's history. We combine the results with an impactor-crater scaling relationship to determine the crater distribution of Ceres and Vesta and compare these theoretical predictions with observations. We find that: (i) The Ceres and Vesta chronologies are similar, whereas they significantly differ from the lunar chronology. Therefore, using the lunar chronology for main belt asteroids, as often done in previous publications, is incorrect. (ii) The model results match the number and size distribution of large (diameter >90 km) craters observed on Vesta, but overestimate the number of large craters on Ceres. This implies that large crater erasure is required for Ceres. (iii) In a model where planetary migration/instability happens early, the probability to form the Rheasilvia basin on Vesta during the last 1 Gyr is 10%, a factor of ∼1.5 higher than for the late instability case and ∼2.5 times higher than found in previous studies. Thus, while the formation of the Rheasilvia at ∼1 Gyr ago (Ga) would be somewhat unusual, it cannot be ruled out at more than ≃1.5σ. In broader context, our work provides a self-consistent framework for modeling asteroid crater records.
Modeling Radial Velocity Data of Resonant Planets to Infer Migration Histories
Authors: Hadden Sam , Payne Matthew J.
Published: August 2020

A number of giant-planet pairs with period ratios ≲2 discovered by the radial velocity (RV) method may reside in mean motion resonances. Convergent orbital migration and resonant capture at the time of formation would naturally explain the present-day resonant orbital configurations of these systems. Planets that experience smooth migration and eccentricity-damping forces due to a protoplanetary disk should not only be captured into mean motion resonances but also end up in a specific dynamical configuration within the resonance, sometimes referred to as apsidal corotation resonance (ACR). Here we develop a method for testing the hypothesis that a planet pair resides in an ACR by directly fitting RV data. The ACR hypothesis strongly restricts the number of free parameters describing the RV signal, and we compare fits using this highly restricted model to fits using a more conventional two-planet RV model by using nested sampling simulations. We apply our method to HD 45364 and HD 33844, two systems hosting giant-planet pairs in 3:2 and 5:3 resonances, respectively. The observations of both systems are consistent with ACR configurations, which are formally preferred based on the Bayes factors computed from nested sampling simulations. We use the results of our ACR model fits to constrain the possible migration histories of these systems.
Search for Alignment of Disk Orientations in Nearby Star-forming Regions: Lupus, Taurus, Upper Scorpius, ρ Ophiuchi, and Orion
Authors: Aizawa Masataka , Suto Yasushi , Oya Yoko , Ikeda Shiro , Nakazato Takeshi
Published: August 2020

Spatial correlations among protoplanetary disk orientations carry unique information on physics of multiple-star formation processes. We select five nearby star-forming regions that comprise a number of protoplanetary disks with spatially resolved images with ALMA and Hubble Space Telescope, and we search for the mutual alignment of the disk axes. Specifically, we apply the Kuiper test to examine the statistical uniformity of the position angle (PA: the angle of the major axis of the projected disk ellipse measured counterclockwise from the north) distribution. The disks located in the star-forming regions, except the Lupus clouds, do not show any signature of the alignment, supporting the random orientation. Rotational axes of 16 disks with spectroscopic measurement of PA in the Lupus III cloud, a subregion of the Lupus field, however, exhibit a weak and possible departure from the random distribution at a 2σ level, and the inclination angles of the 16 disks are not uniform as well. Furthermore, the mean direction of the disk PAs in the Lupus III cloud is parallel to the direction of its filament structure and approximately perpendicular to the magnetic field direction. We also confirm the robustness of the estimated PAs in the Lupus clouds by comparing the different observations and estimators based on three different methods, including sparse modeling. The absence of the significant alignment of the disk orientation is consistent with the turbulent origin of the disk angular momentum. Further observations are required to confirm/falsify the possible disk alignment in the Lupus III cloud.

We present an overview of the CMZoom survey and its first data release. CMZoom is the first blind, high-resolution survey of the Central Molecular Zone (CMZ; the inner 500 pc of the Milky Way) at wavelengths sensitive to the pre-cursors of high-mass stars. CMZoom is a 550 hr Large Program on the Submillimeter Array that mapped at 1.3 mm all of the gas and dust in the CMZ above a molecular hydrogen column density of 1023 cm−2 at a resolution of ∼3″ (0.1 pc). In this paper, we focus on the 1.3 mm dust continuum and its data release, but also describe CMZoom spectral line data which will be released in a forthcoming publication. While CMZoom detected many regions with rich and complex substructure, its key result is an overall deficit in compact substructures on 0.1–2 pc scales (the compact dense gas fraction: CDGF). In comparison with clouds in the Galactic disk, the CDGF in the CMZ is substantially lower, despite having much higher average column densities. CMZ clouds with high CDGFs are well-known sites of active star formation. The inability of most gas in the CMZ to form compact substructures is likely responsible for the dearth of star formation in the CMZ, surprising considering its high density. The factors responsible for the low CDGF are not yet understood but are plausibly due to the extreme environment of the CMZ, having far-reaching ramifications for our understanding of the star formation process across the cosmos.
Optimizing Numerical Simulations of Colliding Galaxies. II. Comparing Simulations to Astronomical Observations
Authors: Ogden Matthew , West Graham , Wallin John , Sinkala Zachariah , Smith William
Published: August 2020

Our research focuses on determining the dynamical orbital parameters associated with galaxy collisions. We are accomplishing this by optimizing numerical models of galactic interactions with astronomical observations of colliding galaxies and measuring the uncertainty in the parameter space of these models. This paper will focus on how we compare our numerical models to observed colliding galaxies. We create gravitational n-body models that capture the tidal distortions from galaxy collisions. The final particle positions are then processed to create model images that have realistic intensity profiles and resolutions. We compare the model’s output with the astronomical images to obtain an objective machine score that should reflect the fitness of the model. To test our scoring methods, we then compare our machine scores to the human-scores obtained from the citizen science project Galaxy Zoo: Mergers.

Introduction: The mother plays a fundamental role in the constitution and regulation of her child's healthy microbiota, however, preterm newborns are separated from their mothers soon after birth and transferred to Neonatal Intensive Care Units, being exposed the constant risk for the development of multidrug-resistant microorganisms’ infections. The aim of this study was to explore the multidrug-resistant microorganism colonization of hospitalized babies and their mothers in the neonatal unit context.

Methodology: A prospective case study conducted with hospitalized babies and their mothers in the Neonatal Unit at a university hospital. The sample was composed of 433 binomials (mother-child). Colonization culture samples were taken at the moment of the baby’s discharge, via two swabs in the oral, nasal, axillary, inguinal, and rectal regions.

Results: The colonization incidence among the binomials, 30 (6.9%) were both colonized by multi-resistant microorganisms. Mothers of colonized babies (24.4%) demonstrated a higher chance of colonization in comparison to mothers of non-colonized babies (11.9%) (p = 0.002). Relationships were drawn between baby colonization and prematurity, extremely low birth weight, and non-exclusive maternal breastfeeding (p<0.05). ESBL-producing Gram-negative microorganisms were more frequent in the cultures of the binomials, with 35.9% of the babies colonized with Klebsiella spp. ESBL and 42.0% of the mothers with Escherichia coli ESBL. Furthermore, 50% of the binomials were colonized with E. coli ESBL.

Conclusion: The prematurity, extremely low birth weight, and non-exclusive breastfeeding at hospital discharge were associated with baby colonization by multidrug-resistant microorganism. Furthermore, mothers of colonized children presented higher chances of colonization.

Introduction: Staphylococci are the most important agents associated with bovine mastitis. This study aimed at characterizing resistance factors to antimicrobials in Staphylococcus spp. isolated from the milk of cows with subclinical mastitis.

Methodology: In vitro resistance of 243 Staphylococcus spp. isolates to antimicrobials commonly used in clinical practice was evaluated. The detection and expression of genes encoding resistance mecA (gene encoding penicillin binding protein 2a) mecALGA251 (mecA homologue), blaZ (gene encoding penicillin resistance), femA and femB (genes encoding essential factors - A and B - for the expression of methicillin resistance) and aacA-aphD (gene encoding for a bifunctional enzyme that confers resistance to gentamicin) using PCR and RT-PCR was investigated.

Results: One or more genes encoding resistance to different antimicrobials were detected in 184 Staphylococcus spp. samples. The femA and femB genes were the most frequent. Regarding the variables’ detection (N = number of strains) and expression (% of strains), the following results were obtained: blaZ (N = 40 – 82.5%), femA (N = 147 – 47.6%), aacAaphD (N = 30 – 43.3%), femB (N = 138 – 29.7%), mecA (N = 33 – 27.3%), mecALGA251 (N = 01 – 0.0%). There was a higher occurrence of phenotypic resistant strains for amoxicillin, ampicillin and penicillin in isolates positive for detection and/or expression of blaZ gene when compared with the other genes.

Conclusions: The present study provides new information on genotypic traits of Staphylococcus isolates from bovine subclinical mastitis especially regarding the evaluation of expression of genes associated with antimicrobial resistance in Staphylococcus spp. using molecular tools.

The COVID-19 pandemic has affected 187 countries, representing a global public health problem. The increasing number of critically ill patients and deaths have fueled a desperate search for treatments that can halt the course of the disease. Currently, there are several experimental therapies with demonstrated in vitro activity against COVID-19 used in clinical practice, including hydroxychloroquine, remdesivir, interleukin-6 pathway inhibitors, and convalescent plasma; however, to date no agent has proven efficacy against COVID-19. In the case of convalescent plasma, this therapy consists in obtaining neutralizing antibodies from previously infected individuals by plasmapheresis and administering them to patients with severe disease. Recently, the use of convalescent plasma has shown promising results in preliminary studies, with case series reporting a decrease in temperature, and viral load, as well as improvement in clinical parameters among patients receiving this treatment. However, there are still unmet needs regarding the safety profile, tolerability, dosage, and timing this therapy should be given. Based on this, the objective of our study was to develop and propose a practical approach for the compassionate use of convalescent plasma for the treatment of patients with severe COVID-19, given the constrains and limitations of developing countries. We encourage health professionals in developing countries to use the current evidence and approaches to experimental treatments for patients with COVID-19, adapting them to their conditions, and always based on a thorough risk-benefit evaluation for each patient, and whenever possible to design and promote the much needed research in this field.

Introduction: The numbers of people infected with SARS-CoV-2 in Indonesia especially in Jakarta as the epicenter continue to rise. Limited published clinical data, scarcity and long turn over time of diagnostic testing put clinician in dilemma to make diagnosis.

Methodology: This is an observational case series study from confirmed COVID-19 patient in our hospital from first case admission on 17 March 30 April, 2020. We collected patient’s demography, symptoms, comorbidities, therapy, laboratory, chest x-ray and ECG consecutively.

Results: Between 17 March 2020 and 30 April 2020, there were 30 confirmed COVID-19 cases, 16 (53.3%) were male. Clinical symptoms were dyspnea in 22 (73.3%) and dry cough 16 (53.3%). Comorbidities were diabetes in 14 (46.6%), hypertension 10 (33.3%) and Coronary Artery Disease (CAD) in 10 (33.3%) patients respectively. Laboratory findings showed lymphopenia in 21 (70%) patients, increased inflammation marker in Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP) and Lactate Dehydrogenase (LDH) 21 (70%), 23 (76.6%) and 12 (40%) patients respectively. Twenty-seven (90%) cases had abnormal Chest X-Ray (CXR) and mostly severe 18 (60%). Descriptive finding for images included consolidation 16 (53.3%) and Ground Glass Opacities (GGO) in 10 (33.3%) patients.

Conclusions: Based on our findings, most cases of COVID-19 admitted in secondary referral hospital were already in moderate to severe stages. This is most likely due to late referral from primary care and unspecific clinical features resemblance of other infectious diseases. Inflammation marker and CXR are cost effective findings and can be used as marker to determine further referral.
The The risk of public mobility from hotspots of COVID-19 during travel restriction in Bangladesh
Authors: Ghosh Probir , Mollah Mohammad Manir
Published: August 2020

Bangladesh reported the first three laboratory-confirmed COVID-19 cases on March 8, 2020 in Dhaka and Narayanganj cities. As of April 8, 2020, 218 confirmed cases across the country, they have mostly detected from Dhaka (56.4%) and Narayanganj (21%) cities where the hotspots of an outbreak of COVID-19 disease. There were 6 cases in Dhaka district excluding metropolitan areas and rest of 43 (20%) cases in the 19 other regions. Local government-enforced completely shut down the hotspots areas on April 8 2020. However, peoples from hotspots travelled openly to the other districts.

We aimed to understand the risk of open movement from hotspots. We studied 40 individuals who were infected with SARS-CoV-2 virus later at their destination. We developed a route map and density maps using Geographic Information System (GIS). Among the studied people, the average distance was 140.1 (75.1) kilometers (Km), and the range of distance was from 20.3 to 321.7 kilometers. Among them, 42.5% traveled <100 Km, 40.0% traveled between 100 and 200 Km and 17.5% traveled above 200 Km. Case numbers were increased 13.5 times more on April 20 than the cases as of April 8, 2020.

Our analysis suggests that relaxed travel restriction could play an important role to spread COVID-19 transmission domestically. To reduce further spread of COVID-19, the government should closely monitor the public health intervention to stop the casual movement.

Introduction: The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 (COVID-19). First COVID-19 case was detected in March, 10, 2020 in Turkey and as of May, 18, 2020 148,067 cases have been identified and 4096 citizens have died. Tuberculosis (TB) is a worldwide public health concern, incidence of tuberculosis (per 100,000 people) in Turkey was reported at 14, 1 in 2018. During pandemic COVID-19 was the main concern in every clinic and as we discuss here overlapping respiratory diseases may result in delaying of the diagnosis and treatment.

Methodology: There were 4605 respiratory samples examined between March 23 and May 18 for COVID-19 and 185 samples for Mycobacterium tuberculosis in our laboratory. The Xpert Ultra assay was performed for the diagnosis of pulmonary tuberculosis; SARS-CoV-2 RNA was determined by real-time PCR (RT-PCR) analysis in combined nasopharyngeal and deep oropharyngeal swabs of suspected cases of COVID-19.

Results: Both of SARS-CoV-2 and M. tuberculosis tests were requested on the clinical and radiological grounds in 30 patients. Here we discussed 2 patients who were both COVID-19 and TB positive. One patient already diagnosed with tuberculosis become COVID-19 positive during hospitalization and another patient suspected and treated for COVID-19 received the final diagnosis of pulmonary TB and Human Immunodeficiency Virus infection.

Conclusions: We want to emphasize that while considering COVID-19 primarily during these pandemic days, we should not forget one of the “great imitators”, tuberculosis within differential diagnoses.

To investigate fungi from the Qilian Mountains in Gansu Province, ascomycetous specimens were collected and hypocrealean fungi were examined. Eighteen species belonging to six genera in the families Hypocreaceae and Nectriaceae were identified, including 11 species of Hypomyces and Trichoderma in Hypocreaceae and seven species of Nectria, Stylonectria, Thelonectria, and Thyronectria in Nectriaceae. Among them, Stylonectria qilianshanensis and Trichoderma gansuanum are new to science. DNA sequence analyses of combined ACL1, ITS, RPB2, and TEF1 regions confirmed their taxonomic placements. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces tremellicola is reported for the first time in China.

Here we present a multi-taxa inventory of naturalized alien species recorded on continental Chile and adjacent marine habitats, including eight taxonomic groups. We identified 1,122 species. These comprise 790 vascular plants (terrestrial and aquatic); 31 nonvascular plants [Bryophyta (mosses), Marchantiophyta (liverworts) and Anthocerotophyta (hornworts)]; 18 marine and freshwater macro and micro algae; 71 fungi; 39 terrestrial vertebrates (amphibians, reptiles, mammals and birds); 108 insects; 37 marine and freshwater invertebrates and vertebrates (6 polychaetes, 3 mollusks and 28 Pisces); and 28 terrestrial gastropods. For all taxonomic groups, naturalized species were found to mainly be distributed in regions with Mediterranean and temperate climates, with few at either extreme of the country. The invasion curves show that naturalized species first underwent a positive increment, followed by an apparent plateau phase, mainly in vascular plants, insects and vertebrates. In fungi, marine and freshwater macro and microalgae, vertebrates and invertebrates, the cumulative number of naturalized species increased sharply starting in the early 20th century; the lack of collections before 1900 is also evident. When considering naturalized species as a whole, this inventory highlights that the rate of new naturalizations consistently increased after 1950, especially for some taxonomic groups such as insects, fungi, and vascular plants. This multi-taxa inventory of naturalized species provides a platform for national reporting on biodiversity indicators and highlights areas where Chile must invest resources to manage biological invasions.
Les ruses de la raison budgétaire
Authors: Brissaud Constantin , Juven Pierre-André
Published: August 2020

Cet article revient sur la production, par une organisation internationale – l’OCDE – d’un rapport sur les prix des médicaments « innovants ». Confrontant deux principes historiquement fondateurs de l’engagement de l’OCDE en matière de santé – limiter les dépenses publiques et introduire des « mécanismes de marché » dans des secteurs obéissant à d’autres logiques sociales – l’expertise sur le prix des « médicaments innovants » est prise dans une tension idéologique et un jeu de contraintes structurales que l’article éclaire. D’un côté, les États-Unis, les représentants de l’industrie à l’OCDE (BIAC) et le Département des affaires économiques défendent une lecture « pro-marché », dans laquelle des prix élevés financent l’innovation pharmaceutique. De l’autre, les rédacteurs et rédactrices du rapport principalement membres de la Direction des affaires sociales, plusieurs pays européens, des ONG, et la représentation des syndicats à l’OCDE (TUAC) contestent l’approche économique standard, et remettent en cause les modalités de construction des prix des médicaments « innovants ». En revenant sur le processus de rédaction du rapport et en éclairant les luttes d’intérêt et d’influence à l’œuvre, l’article met au jour les asymétries de position et de ressources entre les deux groupes. Il donne à voir les modalités concrètes de neutralisation de la critique et la tenaille dans laquelle l’OCDE est prise alors que l’extrême profitabilité du secteur pharmaceutique vient heurter l’idéologie de contrôle des dépenses publiques de santé.
