Authors: Morency Jamme , Lyons Kathleen , Root Lynn , Caldon Kate , Hayes Christi , Brighton Susan
Published: September 2020

Date Presented 03/28/20

HSCT is a lengthy and debilitating cancer treatment. Caregivers of HSCT recipients report distress and reductions in their own self-care. A caregiver wellness intervention based on behavioral activation was developed and implemented in order to assess its feasibility and acceptability. Future research will explore the efficacy of the intervention, which is well-suited for delivery by OTs working in cancer rehabilitation.

Effectiveness of Occupational Therapy as a Nonpharmacologic, Multicomponent Intervention in the Treatment of Delirium in Hospitalized Patients
Authors: Monaghan Emma , Rajan Ashna , Blanchard Gary
Published: September 2020

Date Presented 03/28/20

A novel care model was created to assess the effectiveness of OT as a nonpharmacologic, multicomponent intervention in the prevention and treatment of delirium in hospitalized patients. Given that “only 12 to 35% of delirium cases are recognized,” patients with “altered mental status” received priority evaluation from OT (Ramirez, 2014). Preliminary research has been promising and indicates benefits of OT utilization as an effective discipline in the treatment of delirium.

Primitivismo digital. Tinder y la cosmología neoliberal en la captura del amor romántico
Authors: Gómez Gabriel Núria
Published: September 2020

A partir del caso de estudio de la aplicación de citas online Tinder, nos preguntamos acerca de cómo la ideología del Big Data actualiza ciertas referencias arcaicas de las artes adivinatorias. En la cosmología neoliberal de nuestro presente, vivimos un resurgimiento de los sistemas de interpretación de la influencia de los astros que nos habla de una fascinación ancestral por el cielo nocturno y la necesidad de explicar nuestro origen y destino; pero que sobre todo nos habla de una maquinaria de explotación de estas necesidades y de un sistema ávido de explotarlas para sacar un rendimiento económico en base a las características propias del tiempo actual. En el universo computacional del capitalismo digital los algoritmos funcionan como oráculos: tienen la capacidad de determinar el futuro de los usuarios conectados en red según sus patrones de consumo. Los algoritmos ya no son simplemente instrucciones para ser ejecutadas, sino que se han convertido en entidades escénicas que seleccionan, evalúan y transforman las infraestructuras urbanas y las formas de vida.
Conversando con cajas negras; sobre la aparición de los interfaces conversacionales
Authors: Tabarés Gutiérrez Raúl
Published: September 2020

En los últimos años hemos asistido a la aparición casi simultánea de diferentes interfaces conversacionales impulsadas por diversos representantes del capitalismo digital. Dichos interfaces han sido implementados en una variedad de dispositivos y objetos con la finalidad de facilitar la interacción entre humanos y computadoras. Sin embargo, dichas interfaces plantean nuevas problemáticas que están íntimamente asociadas con los modelos de negocio que guían su desarrollo tecnológico, a través de la denominada como “economía de las plataformas”. En el presente texto se hace una revisión de la literatura en torno a dichas plataformas que impulsan el capitalismo digital, prestando especial atención a la aparición de los nuevos interfaces conversacionales. Asimismo, se presta especial atención al proyecto CALO, financiado por la DARPA, y que constituye el germen de muchas de estas innovaciones. En el artículo se argumenta que la introducción de este tipo de interfaces conversacionales facilita la introducción de nuevas desigualdades y amenazas en el espacio online para las comunidades más minoritarias y menos empoderadas por las tecnologías digitales.

Treatment of Kitchen Wastewater using Aerobic Biological Method and Sand-Bed Filtration
Authors: Uwidia Ita E.
Published: September 2020

Increased global demand for freshwater far exceeds the quantity available for human sustenance. Wastewater recycling processes are necessary and capable of producing large volumes of water for reuse. In this study, raw kitchen wastewater was analyzed for physicochemical and microbiological characteristics before and after biological treatment and sand-bed filtration. The results revealed a reduction in the mean values of the following parameters: turbidity (from 6.9 to 6 NTU, a 13.04% reduction), conductivity (365 to 311 µS/cm, a 14.79% reduction), total dissolved solids (141 to 121 mg/L, a 14.18% reduction), total suspended solids (5 to 2 mg/L, a 60% reduction), biochemical oxygen demand (5.5 to 1.82 mg/L, a 66.9% reduction), chemical oxygen demand (36 to 32 mg/L, an 11.11% reduction), and total bacterial count (286 x 10-4 to 16 x 10-4 CFU, a 94.41% reduction). The kitchen wastewater was suitable for non-potable reuse. Biological treatment and sand-bed filtration rendered the kitchen wastewater useful for secondary applications such as irrigation.

Published: September 2020

Pig farming is considered one of the activities with the greatest environmental impact due to the erroneous disposal of swine waste. The present work aimed to produce an organic compost using waste from pig production and evaluate its chemical characteristic, corn yield under doses of this organic compost and soil nutritional quality before and after the experiment implementation. The Corn was fertilized at sowing and 30 days after plant germination using organic compost from pig waste at the doses: 0, 2, 3, 4 and 5 t ha-1. The Corn used was CATIVERDE 02 and were seeded at 1.0 m spacing between rows and 0.40 m between plants, in a total area of 240 m2. The experimental design was randomized blocks with four replications and five doses of organic compost. The parameters evaluated for corn were: plant height, stem diameter, weight and corncob length. Fertilization with swine organic compost increases in soil P, K, Ca, even after the corn harvest. The best treatment was with a dose of 5 t ha-1, as it resulted in higher plant height (1.85 m) and corn cob weight (261 g).

Published: September 2020

Camu-camu is an Amazonian fruit that has high levels of vitamin C, however, there is a need to expand knowledge to carry out systematic and consistent studies in the various fields of knowledge, and those related to mineral nutrition. The objective of this work was to evaluate the nutritional and growth status of camu-camu by the missing element technique and the use of liming, using as substratum a dystrophic Yellow Latosol of central Amazonian texture. The experimental design was a randomized block design with four replications and 15 treatments: complete, liming omission, individual omission of N, P, K, Ca, Mg, S, Zn, Mn, Cu, B, Cl and Mo. of the witness (natural soil). The characteristics evaluated were: height, neck diameter, leaf, stem, shoot, root and total dry matter, relative growth, shoot and root ratio, and nutrient accumulation of shoot (leaf) dry matter. All data evaluated were statistically significant. Liming and fertilization were necessary for acidic and low natural soils when comparing the complete with the control. Ca and P were the most limiting nutrients, while omission of N reduced the growth of seedlings. Based on total dry matter, the nutritional requirement of camu-camu was in decreasing order: Ca > P > S > Cl > Cu > Mg > Z > K > Mo > Mn > B > N.

Published: September 2020

In on-farm trials, the foliolar severity of Asian soybean rust was evaluated in 44 areas, in three regions of Mato Grosso sown in December (2019) and February (2020). Several susceptible cultivars were used in different crop systems; insect pests and weeds were controlled with different management systems by the farmers. Forty soybean leaflets from four plots replications, demarcated at random in each field were taken. In laboratory foliolar severity was appraised. For rust control in the trials conducted in February, fungicides with efficiency greater than 60% were used consisting of DMIs, QoIs and SDHIs in double or triple mixtures, always adding multisites (chlorothalonil, mancozeb, copper oxychloride). The severity was greater in the fields sown in December (4.84% than in February 0.68%). The number of fungicides spraying/ha in December was 6.4 and February 4.6. It is discussed that through the use of multisites fungicides, the mutation potential in Phakopsora pachyrhizi is reduced and that the spores from areas cultivated in February, probably due to unfavorable environment, do not survive during the soybean free-period. Our results indicate that the sowing period can be changed from the end of December to February, since multisites fungicides are always used.

Wheat productivity is compromised by the number of diseases that affect it. The diseases control is basically effected by the use of fungicides, however, biological control has become important due especially to the demand for foods free of chemical compounds. The objective of this work was to evaluate the efficiency of yeasts in reducing diseases through the treatment of wheat seeds and the spraying of plants in the field. The tests were carried out in the field and laboratory, with the yeasts Candida albicans, Cryptococcus laurentii, Pichia guilliermondii, Rhodotorula glutinis, Zygoascus hellenicus and Saccharomyces cerevisiae compared with fungicide (carbendazim) and control with water. In the laboratory, seed health, germination, germination speed index, cold test and accelerated aging were analyzed. In the field, seed treatment and aerial application were carried out when the flag leaf was emitted and the occurrence of diseases, chlorophyll content, production components, productivity and production quality was evaluated. For the variables of production and quality of the wheat in field, the yeast Z. hellenicus was efficient for productivity resembling the fungicide. For the severity of diseases in field, parameters related to germination and seed health, yeasts were not efficient.

Published: September 2020

With intensive cultivation and the lack of crop rotation, the no-tillage system has been showing compacted areas. For its reduction, mechanical scarification and crop rotation has been recommended. Thus, the present study aimed to evaluate in a no-tillage system the effect of mechanical scarification and crop rotation systems on soil porosity and density after 18 months. The experimental design used was randomized blocks in a split-plot scheme, with four replications. The main plots consisted of maintaining the no-tillage system and minimal soil preparation with a chisel, carried out before the cultivation of cover plants. The subplots were composed of different plant species grown in winter: wheat, consortium of forage pea + black oat and consortium of black oat + forage turnip. Both were succeeded by cultivation of soy and lupin. Macroporosity, microporosity, total porosity and bulk density were evaluated. After 18 months, the scarified soil showed a higher bulk density (0.10-0.15 m layer) when compared to the no-tillage system, demonstrating that this isolated decompression alternative does not improve the physical properties of the soil. The area in succession to oat + turnip/soybean/lupin showed lower bulk density.
Effect of Different Honey Concentrations on Survival, Longevity and Reproduction of Trichospilus pupivorus (Hymenoptera: Eulophidae), a Parasitoid of Coconut Black-Headed Caterpillar, Opisina arenosella (Lepidoptera: Oecophoridae)

Published: September 2020

Many coconut producing countries in Asia are facing a serious infestation of Opisina arenosella (Lepidoptera: Oecophoridae) or commonly called the coconut black-headed caterpillar. Recently, the pest has been detected in the coconut (Cocos nucifera) planting area in Pahang, Malaysia. Thus, an initiative to manage the pest by using parasitoids has been started with a study on the effects of diet on survival, longevity and reproduction of naturally occurred parasitoid known as Trichospilus pupivorus (Hymenoptera: Eulophidae). The aim of this study was to identify suitable concentrations of honey that can be used in developing its rearing technique. Two independent experiments were conducted, i.e., a) survival and longevity study; and b) reproduction study. In each study, different honey concentrations were tested on ten (eight replications) and one (five replications) female parasitoids respectively. 30% honey concentrations resulted in high survival rate of the adult during early life with relatively prolonged longevity up to 6.0±0.19 days and significantly produced the highest number of progenies (105.4±0.81). The lowest survival rate was given by 60% honey and significant longevity up to 6.5±0.33 days with no progenies. Further studies on other plausible factors affecting the reproduction and fitness of progenies should also be investigated to ensure efficient rearing techniques.
Selling Wind
Authors: Kakhbod Ali , Ozdaglar Asuman , Schneider Ian
Published: September 2020

We investigate the strategic behavior of wind producers in the presence of uncertain wind resource availability, where wind availability is correlated across firms. We study how the level of correlation between different firms’ wind resources impacts strategy and market outcomes. The main insight of our analysis is that increasing heterogeneity in resource availability improves social welfare, as a function of its effects both on improving diversification and on reducing withholding by firms. We show that this insight is robust for common assumptions regarding electricity demand. The model is also used to analyze the effect of wind resource heterogeneity on firm profits and opportunities for collusion. Finally, we analyze the impacts of improving public information and weather forecasting; enhanced public forecasting increases welfare, but it is not always in the best interests of strategic producers.
Suicide and the Media: From Werther to Papageno Effects – A Selective Literature Review
Authors: Niederkrotenthaler Thomas , Till Benedikt
Published: September 2020

Et betydelig antall studier har vist at sensasjonspregete skildringer av selvmord i media kan utløse imitasjonsselvmord; dette er ofte omtalt som «Werther-effekten». For å forhindre skadelige medieeffekter, har nasjonale og internasjonale organisasjoner utviklet anbefalinger for omtale av selvmord i mediene for å endre praksis i hvordan selvmord beskrives og for å styrke fokuset på selvmordsforebyggende aspekter. I løpet av det siste tiåret har man fått mer kunnskaper som viser at visse typer medieomtale av selvmord kan ha forebyggende effekt. Særlig medie- saker som beskriver personlige erfaringer med selvmords- tanker og hvordan man kan overvinne og takle vanskelige livssituasjoner, har vist seg å redusere suicidalitet i enkelte grupper. Denne beskyttende effekten har blitt kalt Papageno-effekten. I denne artikkelen gir vi en selektiv oversikt over aktuell litteratur om Werther- og Papagenoeffektene for forskjellige typer medier, og legger særlig vekt på nye kunnskaper om Papageno-effekten generert fra randomisert kontrollerte studier. Vi viser hvordan disse effektene kan utnyttes i selvmordsforebyggende arbeid ved samarbeid med media, og peker på fortsatte mangler i kunnskapene som må fokuseres i fremtidig forskning.

Published: September 2020

I 2017 skjedde det uvanleg mange sjølvmord og sjølvmordsforsøk både i Trondheim og i Lillehammer. Trondheim kommune set sjølvmordsåtferda i samanheng med tv-serien 13 Reasons Why. Sjølvmord er eit tema som vekker sterke kjensler, og mange er bekymra for å gjere noko som fører til potensiell smitte. Denne artikkelen er ei usystematisk litteraturgjennomgang som belyser tema smitte, og eg forsøkjer å svare på spørsmålet «Er det noko med tv-serien 13 Reasons Why som potensielt kan fremme sjølvmordståferd hos ungdom?» i lys av forskingslitteraturen. Artikkelen viser òg til verktøy ein kan nytte for å førebyggje smitte og følgje opp ungdom ein er bekymra for.

SVÆRT MANGE AV OSS har en eller annen gang tatt førstehjelpskurs i hjerte-lungeredning i regi av speideren, Røde Kors, Norsk Folkehjelp eller en av de mange andre organisasjonene eller institusjonene som har gitt slik opplæring i Norge de siste 50–100 år. Ideen bak førstehjelp er, som kjent, å gi livreddende behand- ling der og da, før kyndige helsearbei- dere kan overta ansvaret. Dette har reddet utallige liv og er like viktig i dag som i tidligere tider. Den samme ideen ligger bak det å gi førstehjelp ved selvmordsfare. Dessverre har vi ikke like godt utbygget opplæring for denne typen førstehjelpsferdigheter. Det var derfor en milepæl da Vivat Selvmordsforebygging ble etablert for drøye 20 år siden. Siden den gang har Vivat gitt mer enn 50 000 lærere, sykepleiere, politifolk, prester, offiserer og leger (for å nevne noen av de mange gruppene) i alle deler av landet opplæring i hvordan opp- dage selvmordsfare og gi førstehjelp. I dette nummeret av Suicidologi bringer vi artikler om utviklingen av Vivats arbeid og hvilke erfaringer utdanningsprogrammet har bygd opp gjennom to tiår. Suicidologi gratulerer Vivat og det dyktige teamet av lærere og kursledere med jubileet og innsatsen! Siden selvmord berører så å si alle mennesker i samfunnet, trenger også de fleste å ha noe kunnskap om hva de kan gjøre for å hindre at noen skal ta sitt eget liv. Det gjør oppgaven med å spre slik kunnskap formidabel og det er derfor gledelig at også Norges Røde Kors har engasjert seg på dette området i løpet av de siste par årene. I dette nummeret bringer vi stoff om hvordan opplæring av frivillige i Røde Kors har ført til endringer i holdninger, kunnskaper og ferdigheter i møte med personer i selvmordsfare. Vi trenger å nå lenger ut i befolkningen med kunnskaper som kan føre til endring. Vi trenger at folk får øynene opp for det store samfunnsproblemet selvmord og innser at det kan forebygges!

Das Zeitalter der Interdependenz
Authors: Deuerlein Martin
Published: September 2020

Sozialwissenschaftliche Debatten über globale Verflechtungen zwischen den 1960er und den 1980er Jahren.

Ab den späten 1960er Jahren diskutierten Zeitgenossen intensiv über globale Verflechtungen in Weltpolitik und Weltwirtschaft. Mehr als ein Jahrzehnt vor dem Einsetzen der Globalisierungsdebatte erklärten sie ihre Gegenwart zum »Zeitalter der Interdependenz«.

Martin Deuerlein untersucht für die USA und die Sowjetunion erstmals umfassend solche globalistischen Gegenwartsdiagnosen in den Sozialwissenschaften und ihre Wechselwirkungen mit der internationalen Politik. Der Autor zeigt, wie das im 19. Jahrhundert etablierte Verständnis von Interdependenz als Verflechtung nationaler Einheiten ab den 1960er Jahren hinterfragt wurde. Die Zunahme von Welthandel und Finanzströmen, »globale Probleme« wie Hunger und Umweltverschmutzung und die neue Bedeutung multinationaler Unternehmen und anderer transnationaler Akteure ließen Beobachter an bisherigen Annahmen zweifeln. Vor dem Hintergrund des Ost-West- und des Nord-Süd-Konflikts wirkte globale Verflechtung zunehmend bedrohlich und schien neue politische Ansätze zu erfordern. Wie eine den gewandelten Rahmenbedingungen angepasste Weltordnung jedoch aussehen sollte, war heftig umstritten - eine Frage, die bis heute nichts von ihrer Relevanz verloren hat.

Fisheries in Araguari river is an alternative income for families that depend on exploitation of natural resources. This study evaluates fisheries production in high and medium Araguari river to determine the bioeconomic reference points of fishery activities. Logbooks of fisheries were used from Fishermen Colony Z-16 from 2003 to 2010. The Maximum Sustainable Yield (MSY) and Effort at Maximum Sustainable Yield (fmsy) was: MSYSchaefer = 11246 kg and fmsy = 754 fisheries/year, and MSYFox = 11478 kg and fmsy = 1214 fisheries/year and at Bioeconomic Equilibrium (Eebe) Eebe = 10712 kg and Effort at Bioeconomic Equilibrium (febe) febe = 918 fisheries/year. The status of fisheries from Araguari River was declared as overfishing and in this study, we found the same results. The Maximum Economic Yield (MEY) was reached too, as the fisheries were at Bioeconomic Equilibrium (EBE). The fishery mortality (Fyear/Fmsy) and fishery effort (fyear/fmsy) trends show that from 2003 to 2009 the values were sustainable. In 2010 those trends became unsustainable, and the Maximum Economic Yield (MEY) for all years is unsustainable too. It is required this study be considered in future management agreements.

This paper brings a discussion linked to the development of a doctoral research, which aims to know the spaces of Financial Education in Mathematics Degree courses offered by a federal public institution of São Paulo and seek directions for their promotion in these environments. This is a qualitative research, whose data production was through documentary research, interviews and, in particular, the engagement of a group of teacher educators, through a collaborative work practice. The group met during 2018 in a virtual environment to share experiences, share knowledge and broaden understanding on how to promote financial education in initial education courses. In the first phase of the investigation, the teaching plans of subjects focused on financial education of undergraduates were analyzed. The presence of digital technologies was observed in some cases and later discussed within the group of trainers. We share here what the produced data bring about the role of these technologies in shaping the financial education of future mathematics teachers, in dialogue with the contributions of research in mathematics education and digital technologies.
Formulações espectrais para solução de problemas de transporte de partículas

Published: September 2020

In this work, a deterministic approach to the solution of the integro differential linear Boltzmann equation, in one and twodimensional media, is presented. Explicit solutions, in terms of the spatial variables, for the discrete ordinates approximation of the original model are obtained from a spectral formulation. A relevant feature of the methodology is the reduced order of the eigenvalue problems, which is given as half of the number of the discrete directions. Such aspect, along with the use of arbitrary quadrature schemes to represent the integral term of the equation, are fundamental to provide fast, concise and accurate solutions to several problems of interest. In particular, the solutions here are derived for models associated with two different applications: rarefied gas dynamics and neutron transport. Mathematical aspects present in the solution of the two models are emphasized and extensions of the formulation to other applications are commented and referenced.
Eucalyptus forestry in Brazilian Pampa biome: between developmental illusion and sustainable inefficacy
Authors: Rocha Jefferson Marçal da , Rocha Nájila Souza da , Käfer Pâmela Suélen , Cruz Rafael Cabral
Published: September 2020

The objective of this article is to analyze how the strategy for the implementation of eucalyptus monoculture in the Brazilian pampa Biome had repercussions on economic, social and environmental aspects. It makes a historical rescue of the formation of the economic development of the region, noting that the forestry project for the region has not escaped the expectations of other strategies imposed on the region in the past, the concentration of wealth of the agrarian elite has never been threatened. Extensive livestock farming, until the beginning of the 20th century, grain monoculture, after World War II, and from the 2000s, forestry, have always been linked to a single logic: the accumulation of capital in the hands of the bourgeoisie. The most aggravating factor in eucalyptus production is the mischaracterization of the Pampa biome, which the richness of this ecosystem, even though it requires better studies, is not taken into account in the policy of forestry expansion. For a legitimate development process is necessary to find endogenous mechanisms to promote development compatible with the improvement of the poorest population and the maintenance of the wealth of the Pampa biome. Factors disregarded in the developmental alternatives proposed for the region to date.
Existence and decay rates for a semilinear dissipative fractional second order evolution equation
Authors: Charão Ruy Coimbra , Horbach Jaqueline Luiza
Published: September 2020

In this work we study the existence and uniqueness of solutions and decay rates to the total energy and the L2-norm of solution for a semilinear second order evolution equation with fractional damping term and under effects of a generalized rotational inertia term in the case of plate equation. This system also includes equations of Boussinesq type that model hydrodynamic problems. We show decay rates depend- ing on the fractional powers of the operators and using an asymptotic expansion of the solution to the linear problem, we prove for some cases depending on the exponents of the operators, the optimality of the decay rates.
Impacto do uso do filtro “velocidade de fricção” em estimativas anuais de carbono sobre ecossistemas de pastagem natural

Published: September 2020

Annual carbon estimation of the most diverse ecosystems is a recurring theme in meetings that address climate change mitigation, as it is essential to have a realistic inventory of carbon stock in the biosphere and the ability to assimilate atmospheric carbon. Measurements of CO2 flux over ecosystems after being taken undergo rigorous post-processing to remove spurious and unrealistic data. In addition, a correction for low turbulence situations, where the eddy-covariance technique may be underestimated, is to take the friction velocity (u*) as a threshold to establish valid measurements, especially at night. This method, although widely used by the scientific community, is not unanimous. Especially since u* is itself a flow and consequently its value correlates with the time scale used for the analysis. This paper presents the annual carbon estimate of a natural pasture ecosystem, Pampa biome, in an experimental site established in Santa Maria - RS. We evaluated three distinct situations in the annual carbon estimate (NEP): i) without a u* filter; ii) with a fixed filter u* for all evaluated years and; iii) with the filter u* varying seasonally. The methodology used to estimate u* is the same as that used by Papale et al. (2006). The results show a total annual carbon sequestration variability of up to 10% depending on the methodology employed. The ecosystem in question, regardless of the method used, proved to be a carbon sink. However, the use of one methodology or another in ecosystem situations that are close to carbon assimaltion neutral should be closely scrutinized for an accurate annual balance.
Índices termodinâmicos durante a campanha GOAmazon2014/5 e comparação com dados da reanálise ERA-Interim
Authors: Silva Matheus Tolentino da , Barbosa Henrique De Melo Jorge , Pauliquevis Júnior Theotonio Mendes
Published: September 2020

The thermodynamic indexes LCL, LFC, CINE and CAPE characterize atmospheric instability, and allow the study of cloud formation and convection, important phenomena for the hydrologic cycle and the radiative balance. For this reason, this work makes a seasonal analysis of these thermodynamic indexes computed from radiosondes released during the GOAmazon2014/5 experiment. A comparison was made with ERA-Interim reanalysis for both these indexes and the temperature and relative humidity profiles. Analysis of radiosonde data shows that the median vertical profile of relative humidity in the dry season was lower in 2015 when compared to 2014, resulting in higher LCL (~50 hPa at 18 Z) and lower CAPE (~50% lower). The difference stems from a more severe dry season in 2015 when compared with 2014. The comparison with the reanalysis reveals that modeled LCL values are only compatible with observed ones at 18 Z (mean bias -10 hPa). On the other hand, CAPE values are always incompatible (mean bias -750 j/kg). Results indicate that ERA Interim poorly represents the thermodynamic conditions over the Amazon rainforest.
Estimativa da altura da camada limite planetária no Centro de Lançamento de Alcântara

Published: September 2020

Sea and land breeze circulation and the internal boundary layer are some aspects that make it difficult to determine the coastal Planetary Boundary Layer (PBL) height (h). This paper evaluates the h estimation for the Alcantara Launch Center (CLA) in Maranhão state using 14 months of remote measurements obtained by a ceilometer and by the ERA5 reanalysis. This response depends on the concentration of aerosols and atmospheric humidity present. Mean results indicated that dry months (September to November, with  = 637  488 m) tend to have less hourly and seasonal variability of h compared to wet months (March to May, with  = 770  912 m). A higher mean error in the wet season was obtained with ERA5 PBL h (h = 708  53 m over the land; e h = 648  46 m over the ocean) than in the dry season (h = 18  89 m; e h = 46  77 m). The greater amount of atmospheric humidity during the rainy season increases the estimation uncertainty. This condition was more frequent at night due to typical rainfall in the place.

The objective of this work was to present a preliminary methodology that is able to identify some characteristics of the relationship between the sea breeze circulation and the Amazonian squalline, aiming to understand a little more of the necessary conditions for the deepening of the associated cloudiness. The wavelet transform was applied to the wind and divergence data of ERA5 reanalysis, and a classification was afterwards developed to highlight exclusively the days considered the ideal active period to formation and intensification of the sea breeze circulation and initiation of the Amazonian squalline. The results showed that the relationship between the sea breeze circulation and the Amazonian squalline may be related to the influence of wind at 800 hPa and divergence at 200 hPa. The analysis of average field of the active period days ideal for formation and intensification of the sea breeze circulation and initiation of the Amazonian squalline was able to represent important wind-related characteristics (low level jet between 850 and 750 hPa) and divergence at 200 hPa, indicating that these characteristics, before being directly related to the Amazonian squalline, may first influence the sea breeze circulation performance and intensification.

The total above-ground thermal energy storage rate (S) over an area of a “terra firme” forest site in central Amazonia, Brazil, were estimated through of the direct measurements of heat flux componentes (S Obs) as well as through methodologies proposed by Michiles (2009), in which numerical analysis (S Num) and simple harmonic functions (S Mod) were applied, this last one, due to heterogeneity and biodiversity of the Amazon rainforest, of difficulties and errors related with measurement, a limited range of data were used. Were determined, during dry season of 2003, a set of forest information and meteorological variables measured through systems installed in a micrometeorological tower, assembled at Reserva Biológica do Cuieiras. In this period, days without rainfall and with little atmospheric disturbances were selected. In the daily average maximum behavior, S  Obs showed the highest magnitudes, reaching up to 200 W m-2, while S  Mod and S  Num remained with lower values, about 62 and 108 W m-2, respectively. About 5 and 6 pm (local time), the energy release process was started, with all rates becoming negative and the daily average minimum behavior reached values between -45 and -67 W m-2.

A new module has been developed by the limited area model BRAMS to parameterize a wind farm power plant. BRAMS is developed to be a system for numerical weather prediction, and it is currently employed for operational environmental prediction by the CPTEC/INPE. The new module was able to simulate the impact from a set of wind turbines. The additional drag from turbines changes the turbulent kinetic energy (TKE). Some simulations were carried out considering wind power plant installed on the Brazilian territory.

The current study explores the effects of physical spacing within mathematical expressions on student performance. A total of 2,152 students in 5th-12th grade were randomly assigned to one of four conditions within an online problem set, with terms in algebraic expressions spaced 1) neutrally, with no spaces in the expression, 2) congruent with the order of precedence through grouping terms, 3) incongruent with the order of precedence, or 4) mixed, a combination of the previous conditions. Results show that students who viewed incongruent problems made more errors and had to solve more problems to complete the assignment than those who viewed congruent or neutrally spaced problems. Additionally, students who viewed problems with mixed spacing had to solve more problems to complete the assignment than students who viewed congruent problems. These findings suggest that viewing expressions with spacing that is incongruent with the order of precedence presents challenges for students. Overall, these results replicate prior research in perceptual learning in a natural homework environment and support the claim that physical spacing between terms does influence student performance on order of precedence problems.
Mediação, Formação e Políticas Públicas nos Anos de 1990 na Cidade de Jacareí
Authors: Oliveira Ronaldo Alexandre de
Published: September 2020

O estudo apresentado neste artigo é uma reflexão sobre uma série de atividades educativas desenvolvidas a partir de exposições de artes visuais, organizadas pela Secretaria Municipal de Educação da cidade de Jacareí/São Paulo, na década de 1990, que se traduziram como ações mediadoras entre a arte e os diferentes públicos envolvidos. Ao recuar no tempo, o artigo toma uma das dezessete exposições realizadas e catalogadas, e, por meio de uma descrição analítica, busca compreender os propósitos que gestaram estes projetos, os modos como os mesmos foram planejados e construídos, o seu alcance e impacto, além de reverberações, ao longo do tempo, para o ensino de arte. Sendo assim, o principal objetivo é analisar o sentido de mediação atrelado à formação, de maneira mais abrangente. Para tal análise, tomamos materiais, tais como documentos oficiais e narrativas de pessoas que estiveram envolvidos neste processo, de modo a oferecer uma avaliação crítica das políticas públicas de então.

Les médias : un reflet de la relation entre homogénéité et hétérogénéité sociale
Authors: Gervais Roger
Published: September 2020

Par l’entremise des idées diffusées par les médias écrits, cet article étudie la manifestation de la relation entre l’homogénéité et l’hétérogénéité sociales. Notre échantillon, composé de 11 020 articles provenant d’hebdomadaires et de quotidiens canadiens et français, permet d’observer comment deux cultures différentes, une canadienne et l’autre française, peuvent partager des idées similaires, tout en maintenant leur individualité. Si les phénomènes de l’homogénéité et de l’hétérogénéité sont souvent perçus comme contradictoires, cet article mettra cette perception au défi.

Bu çalışmanın amacı, lise öğrencilerinin “yapıcı yurtseverlik” ve “kör yurtseverlik” tutumlarını betimlemektir. Yurtseverlik, eğitim politikası olarak okullarda aktarılan önemli bir duygudur; bir gruba bağlanma, ülkesine karşı duyduğu
sevgi, sadakat, gurur, adanmışlık ve bağlılık duygularını ifade eder. Aile çevresi gibi okul da çocuklara yurtseverlik tutumlarının kazandırılmasında en etkili sosyalleşme ortamıdır. Başarılı sosyalleşmenin göstergesi ülkesine
bağlılıktır. Etkili yurttaşlık, ancak yapıcı yurtseverlik ile birleştirildiğinde işlevsel olacaktır. Bu çalışmada yapıcı ve kör yurtseverlik ile cinsiyet, okul türü, okunan kitap türü ve okuma sıklığı arasında anlamlı bir farklılaşma
olup olmadığına bakılmıştır. Bunun için nicel araştırma yöntemlerinden betimsel tarama deseni kullanılmıştır. Araştırmaya Sivas İl Milli Eğitim Müdürlüğüne bağlı 10 farklı liseden 866 öğrenci katılmıştır. Verilerin toplanmasında
Yazıcı ve Yazıcı (2010) tarafından Türkçeye uyarlanan “Yurtseverlik Tutum Ölçeği” kullanılmıştır. Verilerin analizinde SPSS-24 paket programı kullanılmıştır. Araştırma sonucunda kız ve erkek öğrenciler arasında yapıcı yurtseverlik
tutumları açısından anlamlı bir farklılık görülmezken erkek öğrencilerin kör yurtseverlik tutumları yüksek çıkmıştır. Fen Lisesi öğrencilerinin yapıcı, İmam Hatip Lisesi öğrencilerinin ise kör yurtseverlik puanlarının yüksek çıkmıştır.
Kitap okuyanların sayısı arttıkça yapıcı yurtseverlik puanları yükselirken az kitap okuyan, hatta hiç kitap okumayanların kör yurtseverlik tutumları yüksektir. Tarih ve dini kitap okuyan öğrencilerin kör yurtseverlik tutumları
yüksek çıkarken felsefe türü kitap okuyanların yapıcı yurtseverlik tutumları yüksek çıkmıştır.
Scale of Labelling the Refugees: Validity and Reliability Study

Mülteci sorunu başta Türkiye olmak üzere, hem savaş bölgelerine sınırları olan ve hem ekonomik gelişmişliğe sahip ülkelerin yaşadıkları başlıca sıkıntılardandır. Göç akını, tek taraflı olarak sadece göç edilen ülkenin sorunu olarak
kalmamaktadır. Savaş ve doğal afet gibi büyük sorunlardan kaçan mülteciler, gittikleri ülkede başka sorunlarla karşılaşabilmektedir. Başta ideolojik olmak üzere birçok nedenle tam sosyal kabulden men edilebilen mülteciler, önce
ırksal önyargıya, devamında da suçlayıcı etiketlemelere maruz kalabilmektedirler. Etiketlemenin toplumsal kabul görmesiyle birlikte, mültecilerin toplumun huzuru ve güvenliği için bir tehdit unsuru olduğu algısı yerleşik hale gelebilmektedir.
Bu algının; muhtemel çatışmalara neden olmaması için politika yapıcıların önlem alabilmesi açısından, yerel halkın mültecilere yönelik suçlayıcı etiketleme tutumlarının ölçülebilmesine ihtiyaç vardır. Bu kapsamda oluşturulan 8
maddelik ve tek boyutlu ölçme aracı 439 kişiden elde edilen verilerle güvenirlik ve geçerlik testlerine tabi tutulmuştur. Kaiser-Meyer-Olkin (KMO) değerinin, .89 ile ‘çok iyi’ olduğu ve Barlett küresellik testinin anlamlı olduğu
tespit edilmiştir. Toplam varyasın % 58.066’sı açıklama yeteneğine sahip ölçeğin, ölçülmek isteneni ayırt etme özelliğine sahip olduğu görülmüştür. Doğrulayıcı Faktör Analizi sonucu elde edilen değerlerin ise ‘iyi uyum’ gösterdiği,
dolayısıyla da yapı geçerliliğinin doğrulandığı anlaşılmıştır. Bu çalışma Bingöl Üniversitesi Bilimsel Araştırma ve Yayın Etik Kurul Başkanlığı’nın 26.12.2018 tarihli ve karar numarası 58 olan izni ile yapılmıştır.
