Authors: Seviani DN , Rahayu Gayuh , Hidayat Iman 
Published: June 2020

Produktivitas tanaman pangan dan hortikultura seperti kedelai, sorgum manis, cabai, dan Chinese cabbage diduga dapat ditingkatkan melalui simbiosis dengan cendawan endofit. Cendawan endofit koleksi IPB Culture Collection strain IYT30, IYT50, IYT64, IYT65, dan IYT102 belum diketahui potensi endosimbiosisnya. Oleh sebab itu penelitian ini bertujuan untuk menguji potensi simbiosis cendawan endofit tersebut terhadap tanaman pangan dan hortikultura yaitu kedelai, sorgum manis, cabai, dan Chinese cabbage pada sistem interaksi kultur aksenik. Endosimbiosis diamati dengan adanya kolonisasi cendawan endofit pada jaringan akar, serta pertumbuhan tanaman inangnya (tinggi tajuk, jumlah daun, panjang akar,
dan bobot kering biomassa). Hasil penelitian menunjukkan akar kedelai dan sorgum manis tidak dapat bersimbiosis dengan cendawan endofit pada kondisi uji. Oleh sebab itu pertumbuhan tanaman lebih dipengaruhi faktor-faktor selain simbiosis. Pada akar cabai dan Chinese cabbage, kolonisasi hanya mencapai ruang antar sel jaringan korteks, kecuali pada
perlakuan IYT64 pada tanaman cabai dimana kolonisasi sampai ke dalam sel. Tanaman yang diinteraksikan dengan cendawan menunjukkan respon yang tidak konsisten pada semua parameter pertumbuhan.

Published: June 2020

O conceito de imagem corporal está baseado a partir de um construto multidimensional, formado das representações sobre o tamanho e aparência do corpo. Objetivou-se a verificar de forma sistematizada a literatura estudos que apresentassem a relação entre satisfação da imagem corporal e variáveis sexuais. Os resultados demonstraram que a área que estuda a percepção da imagem corporal em bailarinos ainda não percebeu a importância de outras dimensões como identidade de gênero, orientação sexual e os esquemas de gênero do autoconceito, que podem ter maior impacto do que apenas o critério sexo biológico. O sexo biológico ainda é a principal variável de controle na comparação nos estudos entre os bailarinos, sendo urgente a necessidade de outras dimensões da identidade a serem incorporadas nos próximos estudos, como as citadas acima, para ampliar a capacidade de explicarmos a satisfação corporal humana.

Esta pesquisa tem como objetivo analisar como está sendo implementada a lei 10.639/2003 pelos professores de educação física no município de Tucuruí/PA. A metodologia utilizada caracteriza-se como uma pesquisa de campo que constitui-se de uma abordagem quali- quanti com caráter exploratório e descritivo. Como instrumento de coleta de dados utilizamos o questionário estruturado com sete questões fechadas relacionadas ao tema para professores de educação física das três escolas selecionadas para este estudo, todos de acordo com a legislação assinaram o termo de consentimento livre e esclarecido (TCLE). Os resultados mostraram que referente ao saber da lei 10.639/2003, apenas 20% dos participantes afirmaram conhecer esta lei, 95% acreditam que o PPP da escola não comtempla a discursão desta temática, fator que contribui para o preconceito racial na educação básica, que teve 70% de reconhecimento a existência no cotidiano das escolas brasileiras. Diante da pesquisa realizada, constatou-se que a lei 10.639/2003 vem sendo pouco ministrada no cotidiano das escolas municipais contempladas. Os trabalhos realizados que abrangem a presente temática são abordados apenas na semana da consciência negra. Este estudo teve como referência artigos publicados em revistas cientificas, Google acadêmico e sites de pesquisa acadêmica.
The fate of O+ ions observed in the plasma mantle: particle tracing modelling and cluster observations

Published: June 2020

Abstract. Ion escape is of particular interest for studying the evolution of the
atmosphere on geological timescales. Previously, using Cluster-CODIF data,
we investigated the oxygen ion outflow from the plasma mantle for different
solar wind conditions and geomagnetic activity. We found significant
correlations between solar wind parameters, geomagnetic activity
(Kp index), and the O+ outflow. From
these studies, we suggested that O+ ions observed in the plasma
mantle and cusp have enough energy and velocity to escape the magnetosphere
and be lost into the solar wind or in the distant magnetotail. Thus, this
study aims to investigate where the ions observed in the plasma mantle end
up. In order to answer this question, we numerically calculate the
trajectories of O+ ions using a tracing code to further test this
assumption and determine the fate of the observed ions. Our code consists
of a magnetic field model (Tsyganenko T96) and an ionospheric potential
model (Weimer 2001) in which particles initiated in the plasma mantle
region are launched and traced forward in time. We analysed
131 observations of plasma mantle events in Cluster data between 2001
and 2007, and for each event 200 O+ particles were launched with
an initial thermal and parallel bulk velocity corresponding to the
velocities observed by Cluster. After the tracing, we found that 98 % of
the particles are lost into the solar wind or in the distant tail. Out of
these 98 %, 20 % escape via the dayside magnetosphere.
Annual dynamics of global land cover and its long-term changes from 1982 to 2015

Published: June 2020

Abstract. Land cover is the physical material at the surface of the Earth. As the cause and result of global environmental change, land cover
change (LCC) influences the global energy balance and biogeochemical cycles.
Continuous and dynamic monitoring of global LC is urgently needed. Effective
monitoring and comprehensive analysis of LCC at the global scale are rare.
With the latest version of GLASS (Global Land Surface Satellite) CDRs
(climate data records) from 1982 to 2015, we built the first record of
34-year-long annual dynamics of global land cover (GLASS-GLC) at 5 km
resolution using the Google Earth Engine (GEE) platform. Compared to earlier
global land cover (LC) products, GLASS-GLC is characterized by high consistency, more
detail, and longer temporal coverage. The average overall accuracy for the
34 years each with seven classes, including cropland, forest, grassland,
shrubland, tundra, barren land, and snow/ice, is 82.81 % based on 2431
test sample units. We implemented a systematic uncertainty analysis and
carried out a comprehensive spatiotemporal pattern analysis. Significant
changes at various scales were found, including barren land loss and
cropland gain in the tropics, forest gain in the Northern Hemisphere, and
grassland loss in Asia. A global quantitative analysis of human factors
showed that the average human impact level in areas with significant LCC was
about 25.49 %. The anthropogenic influence has a strong correlation with
the noticeable vegetation gain, especially for forest. Based on GLASS-GLC,
we can conduct long-term LCC analysis, improve our understanding of global
environmental change, and mitigate its negative impact. GLASS-GLC will be
further applied in Earth system modeling to facilitate research on global
carbon and water cycling, vegetation dynamics, and climate change. The
GLASS-GLC data set presented in this article is available at

Catchment export of base cations: improved mineral dissolution kinetics influence the role of water transit time

Published: June 2020

Abstract. Soil mineral weathering is one of the major sources of
base cations (BC), which play a dual role in forest ecosystems: they
function as plant nutrients and buffer against the acidification of
catchment runoff. On a long-term basis, soil weathering rates
determine the highest sustainable forest productivity that does not cause
acidification. It is believed that the hydrologic residence time plays a key
role in determining the weathering rates at the landscape scale. The PROFILE weathering model has been used for almost 30 years to calculate
weathering rates in the rooting zone of forest soils. However, the mineral
dissolution equations in PROFILE are not adapted for the saturated zone, and
employing these equations at the catchment scale results in a significant
overprediction of base cation release rates to surface waters. In this
study, we use a revised set of PROFILE equations which, among other features,
include retardation due to silica concentrations. Relationships between the
water transit time (WTT) and soil water concentrations were derived for each
base cation, by simulating the soil water chemistry along a one-dimensional
flow path, using the mineralogy from a glacial till soil. We show how the
revised PROFILE equations are able to reproduce patterns in BC and
silica concentrations as well as BC ratios (Ca2+/BC, Mg2+/BC and
Na+/BC) that are observed in the soil water profiles and catchment runoff. In contrast to the original set of PROFILE equations, the revised set of
equations could reproduce the fact that increasing WTT led to a decreasing Na+/BC ratio and increasing Ca2+/BC and Mg2+/BC ratios. Furthermore, the total
release of base cations from a hillslope was calculated using a mixing
model, where water with different WTTs was mixed according to an externally
modeled WTT distribution. The revised set of equations gave a 50 % lower
base cation release (0.23 eq m−2 yr−1) than the
original PROFILE equations and are in better agreement with mass balance
calculations of weathering rates. Thus, the results from this study
demonstrate that the revised mineral dissolution equations for PROFILE are a
major step forward in modeling weathering rates at the catchment scale.
What Ayn Never Told Us
Authors: Hardin Dennis C. 
Published: June 2020

Abstract
Understanding Objectivism was Leonard Peikoff's first major teaching endeavor following Ayn Rand's death in 1982. Like Nathaniel Branden's 1971 book The Disowned Self—written after his break with Rand—the lectures addressed complaints reported by students of the philosophy, subject matter Rand may not have approved. Peikoff faults the common mistake of looking at Objectivism through the lens of traditional philosophy. He clarifies the distinct nature of objective methodology and shows how traditional philosophy is hostage to the pernicious mind-body dichotomy. Despite Peikoff's gracious display of empathy, the promise of a more benign nascent Objectivist vanguard was short-lived.
Misguided Arguments
Authors: Gordon David 
Published: June 2020

Abstract
In their book, Equal Is Unfair, Watkins and Brook argue that equality of income and wealth is not needed in order to engage in the creative work required for human flourishing. One can live a successful life even though others have more resources and opportunities. It is contended here that this argument is convincing, but contrary to Watkins and Brook, it does not suffice to rule out all justifications for redistribution.
Ayn Rand and Posthumanism
Authors: Camplin Troy 
Published: June 2020

Abstract
If we humans are truly facing a posthuman future, the shape of that future will in no small part be a consequence of the writings of Ayn Rand. This is the fundamental claim of Ben Murnane in Ayn Rand and the Posthuman— a claim that he supports while discussing the benefits and problems of such a likely Randian future. From seasteading to technologically enhanced humans, the future, it seems, belongs to Ayn Rand and the pioneers of technology she has most influenced.
Violencia percibida por trabajadores de la salud de parte de los usuarios del Servicio de Salud Talcahuano en Lirquén, Chile, 2017
Authors: Vega-Pinochet Hugo 
Published: June 2020

La violencia en los centros de salud, que históricamente afectaba a algunos puestos de trabajo,
actualmente es generalizada. La alta exposición de los trabajadores a agresiones repercute negativamente en su seguridad y salud. Objetivo: Describir la violencia percibida por los trabajadores de la salud de parte de los usuarios del Servicio de Salud Talcahuano en Lirquén, Chile. Métodos: Se realizó en 2017 un estudio descriptivo transversal, en lo cual participaron 155 trabajadores de dos centros de salud pertenecientes al Servicio de Salud Talcahuano.
Los participantes, quienes dieron su consentimiento informado, contestaron un instrumento validado, de autoaplicación, anónimo y confidencial. El análisis se presenta con tablas de distribución, promedios y datos de dispersión. Resultados: Se encontró que el 70,3% de los trabajadores reporta haber sufrido violencia por parte de los usuarios, tratándose en el 85,3% de violencia verbal. Los más afectados son médicos, odontólogos y enfermeros. Los actos de violencia ocurrieron preferentemente en la mañana, durante la espera de su hora o en medio de una atención sanitaria. Las principales causas identificadas fueron el tiempo de espera y la salud mental del usuario. El perfil del agresor corresponde a un paciente adulto sin distinción de sexo. Finalmente, sólo el 9,2% de las agresiones se notificó formalmente; un 30% de los trabajadores considera que el registro es inútil, y un 72,5% considera que la frecuencia de la violencia se mantiene igual o va en aumento. Conclusiones: La violencia de los usuarios afecta a la mayoría de los trabajadores de la salud. Existe mínima notificación formal y escaso registro de las agresiones. Es necesario capacitar a los trabajadores para prevenir y manejar las agresiones.
De eigenzinnige burgerwacht

The self-willed vigilante – normative practices as a basis for evaluation
Citizen engagement in public safety is increasing rapidly. This trend, also known as responsibilisation, causes new dilemmas for (local) goverments. This article is based on a case study on a local group in the Dutch municipality Neder-Betuwe. These vigilantes arrest suspects by using extensive and professional equipment. By using the theory of normative practices this article compares the practices of the vigilantes and the local police. Their attitude to themes as safety, community values and the core values of the Dutch rule of law differs. This puts pressure on cooperation between vigilantes and police officers.
Is digitale buurtpreventie een goed instrument voor burgeropsporing?
Authors: Zoutendijk Jossian , Schram Krista 
Published: June 2020

Do digital neighbourhood watch groups actually contribute to crime reduction?
It is often assumed that digital neighbourhood watch groups lead to more emergency calls and more arrests by the police. This article revolves around the question whether or not these groups actually contribute to reducing crime in the Netherlands. It does so by looking at recent studies and the results of researchers’ own ‘realist evaluation’ of the city of Rotterdam’s policy on digital neighbourhood watch. The latter includes a reconstruction of the program theory and ten case studies with different types of groups. The reconstruction of program theory revealed two main routes to crime reduction: 1) more emergency calls and more arrests by the police and 2) more social control. Chat histories have been studied and moderators, participants, non-participants and professionals were interviewed on their perception of active mechanisms and on the efficacy of their group. None of the respondents believed their group led to an increased number of arrests, but interviews and chat histories show that crime can be reduced by means of social control. Social control by neighbours limits the opportunity for crime and disturbs criminal acts. Other studies in the Netherlands support this finding. The article closes by putting digital neighbourhood watch in a citizen’s perspective with suggestions to improve the efficacy of digital neighbourhood watch groups and the notion that for citizens, crime reduction is not the only or principal goal.

Compreender a avaliação conduzida em um Núcleo de Ensino de uma Unidade de Internação Socioeducativa do DF constitui objetivo de pesquisa discutida neste artigo. Por meio de estudo de caso do tipo etnográfico, utilizou-se para levantamento de dados: observação, questionários, entrevistas semiestruturadas e grupos focais. Fundamentadas no materialismo histórico-dialético, as análises consideraram as categorias metodológicas apontadas por Cury (1985) e as conceituais emersas das significações (AGUIAR e OZELLA, 2006 e 2013; AGUIAR, SOARES e MACHADO, 2015) constituídas por interlocutores. O estudo indicou a necessidade de espaços-tempos coletivos e democráticos que viabilizem uma prática avaliativa com condições de contribuir para a instauração de uma política educacional intersetorial favorável à articulação do trabalho realizado pelo Núcleo de Ensino e demais setores da Unidade de Internação. Avaliar e planejar conjuntamente o processo formativo dos jovens internos concorreria para o enfrentamento de desafios que obstaculizam o direito de aprender, legalmente assegurado a todos os socioeducandos.

Published: June 2020

In this work, we have studied a magnetohydrodynamic, Casson fluid flow with velocity slip over an inclined nonlinearly stretching surface in Non-Darcy porous medium, numerically. In the mathematical model, we have transformed the momentum equation, energy equation and mass concentration equations to non-dimensional ordinary differential equations using similarity variables. We have solved the equations numerically by bvp4c using MATLAB for the numerical computation, and took and axes so that figures are clearly visible. We have discussed and analysed the magnitude of the velocity, temperature, concentration, Local Skin friction, Local Nusselt number and Local Sherwood number using their representative parameters and the effects of these parameters on the respective boundary layer regions using graphs, figures and tables.
Effects of environmental synchrony and density‐dependent dispersal on temporal and spatial slopes of Taylor's law
Authors: Saitoh Takashi 
Published: June 2020

AbstractTaylor's law (TL) is an empirical rule that describes an approximate relationship between the variance and mean of population density: log10(variance) ≈ log10(a) + b × log10(mean). Population synchrony is another prevailing feature observed in empirical populations. This study investigated the effects of environmental synchrony and density‐dependent dispersal on the temporal (bT) and spatial (bS) slopes of TL, using an empirical dataset of gray‐sided vole populations and simulation analyses based on the second‐order autoregressive (AR) model. Eighty‐five empirical populations satisfied the temporal and spatial TLs with bT = 1.943 (±SE 0.143) and bS = 1.579 (±SE 0.136). The pairwise synchrony of population was 0.377 ± 0.199 (mean ± SD). Most simulated populations that obeyed the AR model satisfied the form of the temporal and spatial TLs without being affected by the environmental synchrony and density‐dependent dispersal; however, those simulated slopes were too steep. The incorporation of environmental synchrony resulted in reduced simulated slopes, but those slopes, too, were still unrealistically steep. By incorporating density‐dependent dispersal, simulated slopes decreased and fell within a realistic range. However, the simulated populations without environmental synchrony did not exhibit an adequate degree of density synchrony. In simulations that included both environmental synchrony and density‐dependent dispersal, 92.7% of the simulated datasets provided realistic values for bT, bS and population synchrony. Because the two slopes were more sensitive to the variation of density‐dependent dispersal than that of environmental synchrony, density‐dependent dispersal may be the key to the determination of bT and bS.
