During the first half of 2019, many provinces of Iran were affected by floods, which claimed the lives of 82 people. The present study aimed to investigate the behavioral, health related and demographic risk factors associated with deaths due to floods. We measured the odds ratio and investigated the contribution and significance of the factors in relation to mortality. This case-control study was conducted in the cities affected by flood in Iran. Data were collected on the flood victims using a questionnaire. Survivors, a member of the flood victim’s family, were interviewed. In total, 77 subjects completed the survey in the case group, and 310 subjects completed the survey in the control group. The findings indicated that factors such as the age of less than 18 years, low literacy, being trapped in buildings/cars, and risky behaviors increased the risk of flood deaths. Regarding the behavioral factors, perceived/real swimming skills increased the risk of flood deaths although it may seem paradoxical. This increment is due to increased self confidence in time of flood. On the other hand, skills and abilities such as evacuation, requesting help, and escape decreased the risk of flood deaths. According to the results, the adoption of support strategies, protecting vulnerable groups, and improving the socioeconomic status of flood-prone areas could prevent and reduce the risk of flood deaths.

Diseases from food of animal origin are common health problems in Ethiopia. A cross-sectional study was carried out to estimate health and economic burden, and to identify demographic factors associated with community awareness of foodborne zoonotic diseases in Amhara region, Ethiopia. Data was collected from 435 households in three towns: Gondar, Lalibela and Debark. A retrospective data was also collected from health records in each town. The health burden due to zoonotic diseases was estimated at 0.2, 0.1 and 1.3 DALYs per household per year and at 73.2, 146.6 and 1,689.5 DALYs out of 100,000 populations per year in Gondar, Lalibela and Debark, respectively. The overall health burden due to foodborne zoonotic diseases (aggregated over the 435 households in the three towns) was estimated to be 89.9 DALYs per 100,000 populations per year. The economic impact of foodborne zoonotic diseases in the three towns of Amhara regional state was 278.98 Ethiopian Birr (ETB) (1ETB = 0.025 US Dollar) per household per year and 121,355.68 ETB per year. Costs of preventive measures followed by costs of patients’ time made the highest contribution while costs of diagnosis made the lowest contribution to the total economic burden of foodborne zoonotic diseases. From a total of 435 respondents, 305 (70.1%) had known the presence of zoonotic diseases. Level of education, number of families in the house and income were highly associated with awareness of zoonosis. Although majority of respondents had known zoonotic diseases exists (70.1%) and disease can be acquired from animal source food (63.2%), the health and economic burden associated to foodborne zoonotic diseases are still high. Therefore, changing mindset and practical training aiming in controlling foodborne zoonotic diseases may be suggested to the community in the health improvement extension service.

Introduction

Child mortality has been linked to infectious diseases, malnutrition and lack of access to essential health services. We investigated possible predictors for death and patients lost to follow up (LTFU) for paediatric patients at the inpatient department (IPD) and inpatient therapeutic feeding centre (ITFC) of the Anka General Hospital (AGH), Zamfara State, Nigeria, to inform best practices at the hospital.

Methods

We conducted a retrospective cohort review study using routinely collected data of all patient admissions to the IPD and ITFC with known hospital exit status between 2016 and 2018. Unadjusted and adjusted rate ratios (aRR) and respective 95% confidence intervals (95% CI) were calculated using Poisson regression to estimate the association between the exposure variables and mortality as well as LTFU.

Results

The mortality rate in IPD was 22% lower in 2018 compared to 2016 (aRR 0.78; 95% CI 0.66–0.93) and 70% lower for patients coming from lead-affected villages compared to patients from other villages (aRR 0.30; 95% CI 0.19–0.48). The mortality rate for ITFC patients was 41% higher during rainy season (aRR 1.41; 95% CI 1.2–1.6). LTFU rates in ITFC increased in 2017 and 2018 when compared to 2016 (aRR 1.6; 95% CI 1.2–2.0 and aRR 1.4; 95% CI 1.1–1.8) and patients in ITFC had 2.5 times higher LTFU rates when coming from a lead-affected village.

Conclusions

Our data contributes clearer understanding of the situation in the paediatric wards in AGH in Nigeria, but identifying specific predictors for the multifaceted nature of mortality and LTFU is challenging. Mortality in paediatric patients in IPD of AGH improved during the study period, which is likely linked to better awareness of the hospital, but still remains high. Access to healthcare due to seasonal restrictions contributes to mortalities due to late presentation. Increased awareness of and easier access to healthcare, such as for patients living in lead-affected villages, which are still benefiting from an MSF lead poisoning intervention, decreases mortalities, but increases LTFU. We recommend targeted case audits and qualitative studies to better understand the role of health-seeking behaviour, and social and traditional factors in the use of formal healthcare in this part of Nigeria and potentially similar settings in other countries.

Background

Colorectal cancer (CRC) is a leading cause of cancer-related deaths, with a 5% 5-year survival rate for metastatic disease, yet with limited therapeutic advancements due to insufficient understanding of and inability to accurately capture high-risk CRC patients who are most likely to recur. We aimed to improve high-risk classification by identifying biological pathways associated with outcome in adjuvant stage II/III CRC.

Methods and findings

We included 1062 patients with stage III or high-risk stage II colon carcinoma from the prospective three-arm randomized phase 3 AVANT trial, and performed expression profiling to identify a prognostic signature. Data from validation cohort GSE39582, The Cancer Genome Atlas, and cell lines were used to further validate the prognostic biology. Our retrospective analysis of the adjuvant AVANT trial uncovered a prognostic signature capturing three biological functions—stromal, proliferative and immune—that outperformed the Consensus Molecular Subtypes (CMS) and recurrence prediction signatures like Oncotype Dx in an independent cohort. Importantly, within the immune component, high granzyme B (GZMB) expression had a significant prognostic impact while other individual T-effector genes were less or not prognostic. In addition, we found GZMB to be endogenously expressed in CMS2 tumor cells and to be prognostic in a T cell independent fashion. A limitation of our study is that these results, although robust and derived from a large dataset, still need to be clinically validated in a prospective study.

Conclusions

This work furthers our understanding of the underlying biology that propagates stage II/III CRC disease progression and provides scientific rationale for future high-risk stratification and targeted treatment evaluation in biomarker defined subpopulations of resectable high-risk CRC. Our results also shed light on an alternative GZMB source with context-specific implications on the disease’s unique biology.
Community media’s role in changing centre–periphery relations through participatory, not-for-profit journalism
Authors: Doliwa Urszula , Purkarthofer Judith
Published: December 2021

Traditional notions of journalism focus exclusively on professionals, often embedded in media outlets and publishing houses. However, preceding decades have seen transformations in the understanding of journalism. This contribution sets out to explore the role of community media in working towards the recognition of participatory, not-for-profit journalism, more diverse discourses and enhanced participation, especially in relation to minorities. This research draws on policy documents at the European level, reports from European projects with community media involvement as well as on interviews with community media activists and journalists. As a result, we can show strategies of bringing peripheral actors to the centre by using community media based on access and participation, social inclusion, giving a voice and media literacy development. The study proposes a model of the role of community media in shifting peripheral actors to more central positions.
The ‘other’ in the bowels of the hegemon: US media portrayals of Guam during the United States–North Korea tension
Authors: Fabregat Eduard , Kperogi Farooq A.
Published: December 2021

This article explores how America’s mainline institutional media portrayed Guam, an unincorporated US territory in the Pacific Ocean that is home to important American military bases, in a time of heightened tensions between the United States and North Korea. Guamanians represent marginal racial ‘others’ who are nonetheless ensconced in a consequential part of the US military architecture. Using a combination of topic modelling and network analysis, our study analysed 2480 articles from 44 different mainstream newspapers in the United States between April 2017 and June 2018 in order to examine the contradictory depiction of an ‘other’ that is simultaneously foreign and domestic. Our results present evidence of a hegemonic portrayal of Guam as an intrinsic part of the US as well as a depiction of the threat to Guam as an attack on the US without acknowledging the marginality of Guam and its inhabitants in US politics.

La copia de documentos diplomáticos fue uno de los medios que las primeras embajadas permanentes emplearon para llevar a cabo su misión de recopilación de información de las relaciones diplomáticas de otras formaciones políticas. En el presente estudio observaremos cómo esta práctica fue desarrollada por la primera embajada permanente de la Monarquía Hispánica, la delegación enviada por los Reyes Católicos a Inglaterra entre 1487 y 1508 bajo el liderazgo de Rodrigo González de Puebla, un personaje tan polémico como innovador en las prácticas de recopilación y transmisión de información. A pesar de conocer con mayor detalle algunas de sus novedades, como el uso de la criptografía como medio para ocultar las comunicaciones, otras han pasado más desapercibidas, como la copia de documentación diplomática. Con tal fin analizaremos los restos de esta actividad conservados en el Archivo General de Simancas y los pondremos en contexto con otras evidencias de las relaciones anglocastellanas en esa etapa
Comparison of enzyme-linked immunosorbent assay and Fassisi® bovine immunoglobulin G (IgG) immunoassay for quantification of bovine IgG in neonatal calf serum
Authors: Hampe Marian , Söllner-Donat Stefanie , Failing Klaus , Wehrend Axel
Published: December 2021

Background and Aim: Rapid tests are routinely used to estimate serum immunoglobulin G (IgG) concentrations in diagnosing a failure of passive transfer (FPT) in calves. The study aimed to compare the Fassisi® Bovine IgG (FB-IgG) immunoassay and an enzyme-linked immunosorbent assay for quantifying bovine IgG in neonatal calf serum.

Materials and Methods: A total of 277 calves of 1-10 days of age were used in this study. Blood samples were obtained, and serum was extracted by centrifuging the samples at 2740× g for 5 min at 20°C. The serum was analyzed using the FB-IgG according to the manufacturer's specifications. Serum IgG concentrations were also determined by enzyme-linked immunosorbent assay (ELISA-IgG). FPT was defined as a serum IgG concentration <10 mg/mL.

Results: The mean ELISA-IgG serum concentration was 8.40 mg/mL (SD=7.02, range=0.10-47.50 mg/mL). FPT prevalence based on the ELISA measurements was 66.8%. The prevalence of partial and full FPT based on the FB-IgG was 54.5%. The ELISA-IgG and FB-IgG results were subjected to correlation and regression analysis. Overall sensitivity and specificity of the FB-IgG were 61.1% and 58.7%, respectively. A statistically significant dependence on age was identified in the results.

Conclusion: Our findings suggest that the FB-IgG rapid method is less accurate and provides no other advantages over established methods.

Published: December 2021

Personality is defined as the mix of features and qualities that make up an individual's particular character, including thoughts, feelings, and behaviors. With the rapid development of technology, personality computing is becoming a popular research field by providing users with personalization. Many researchers have used social media data to automatically predict personality. This research uses a public dataset from Kaggle, namely the Myers-Briggs Personality Type Dataset. The purpose of this study is to predict the accuracy and F1-score values so that the performance for predicting and classifying Myers–Briggs Type Indicator (MBTI) personality can work optimally by using attributes from the MBTI dataset, namely posts and types. Predictive accuracy analysis was carried out using the Long Short-Term Memory (LSTM) algorithm with random oversampling technique with the Imblearn library for MBTI personality type prediction and comparing the performance of the method proposed in this study with other popular machine learning algorithms. Experiments show that the LSTM model using the RMSprop optimizer and learning speed of 10-3 provides higher performance in terms of accuracy while for the F1-score the LSTM model using the RMSprop Optimizer and learning speed of 10-2 gives a higher value than the proposed machine learning algorithm so that the model MBTI dataset using LSTM with random oversampling can help in identifying the MBTI personality type.

COVID-19, which has become a global pandemic since March 2020, has tremendously affected human life globally. The negative impact of COVID-19 affects societies in almost all aspects. Implementing quarantine monitoring, also social distancing, and contact tracing are a series of processes that can suppress the new infected COVID-19 cases in various countries. Prior works have proposed different monitoring systems to assist the monitoring of individuals in quarantines, as well as many methods are offered for social distancing and contact tracing. These methods focus on one function to provide a reliable system. In this paper, we propose IoT-based quarantine monitoring by implementing a geofence equipped with social distancing features to offer an integrated system that provides more benefits than one system carrying one particular function. We propose a system consisting of a low cost, low complexity, and reusable wristband design and mobile apps to support the quarantine monitoring system. For the geofencing, we propose a GPS-based geofence system that was developed by taking advantage of the convenience offered by the Traccar application. Meanwhile, we add the notification for social distancing feature with adaptive distance measurement RSSI-based set up in the android application. Based on the experiment we did to validate the system, in terms of wristband-to-smartphone communication, scanning interval in smartphone and advertising interval in wristband is best to set in 7 s for both. For social distancing notification and geofence, we measure the system performance through precision, recall, accuracy, and F-measure.
Microcontroller-Based Lead-Acid Battery Balancing System for Electric Vehicle Applications
Authors: Rospawan Ali , Simatupang Joni Welman
Published: December 2021

In application of lead-acid batteries for electrical vehicle applications, 48 V of four 12 V batteries in a series configuration are required. However, the battery stack is repeatedly charged and discharged during operation. Hence, differences in charging and discharging speeds may result in a different state-of-charge of battery cells. Without proper protection, it may cause an excessive discharge that leads to premature degradation of the battery. Therefore, a lead-acid battery requires a battery management system to extend the battery lifetime. Following the LTC3305 balancing scheme, the battery balancing circuit with auxiliary storage can employ an imbalance detection algorithm for sequential battery. It happens by comparing the voltage of a battery on the stack and the auxiliary storage. In this paper, we have replaced the function of LTC3305 by a NUCLEO F767ZI microcontroller, so that the balancing process, the battery voltage, the drawn current to or from the auxiliary battery, and the surrounding temperature can be fully monitored. The prototype of a microcontroller-based lead-acid battery balancing system for electrical vehicle application has been fabricated successfully in this work. The batteries voltage monitoring, the auxiliary battery drawn current monitoring, the overcurrent and overheat protection system of this device has also successfully built. Based on the experimental results, the largest voltage imbalance is between battery 1 and battery 2 with a voltage imbalance of 180 mV. This value is still higher than the target of voltage imbalance that must be lower than 12.5 mV. The balancing process for the timer mode operation is faster 1.5 times compared to the continuous mode operation. However, there were no overcurrent or overtemperature occurred during the balancing process for both timer mode and continuous mode operation. Furthermore, refinement of this device prototype is required in the future to improve the performance significantly.

This paper presents the design, simulation, realization and analysis of flexible microstrip patch antenna for S-band applications. The proposed design also adopts the conformal structure by utilizing flexible substrate. Conformal or flexible structure allows the antenna to fit with any specified shape as desired. The antenna patch dimensions is 43 mm × 25 mm without SMA connector. The patch is etched on the flexible dielectric substrate, pyralux FR 9111, with a relative dielectric constant of εr = 3 and the thickness of substrate, h = 0.025 mm. The antenna is designed to resonate at 3.2 GHz. The return loss (RL) of the simulation is -35.80 dB at the center frequency of 3.2 GHz. The fabricated antenna prototype was measured at different bending angles scenarios including 0º, 30º, 60º, and 90º. The measurement of antenna prototype shows that the center frequency is shifted to the higher frequency of 3.29 GHz, compared to the simulation result. Among these scenarios, measurement at bending angle of 90º gives the best performance with RL = - 31.38 dB at 3.29 GHz, the bandwidth is 80 MHz, and the impedance ZA = 48.36 + j2.04 Ω. Despite a slight differences from simulation results, the designed antenna still performs well as expected.

Published: December 2021

In this study, an antenna system that could cover the 360ᵒ detection area using the microstrip method was created. The antenna design proposed uses the franklin collinear method with the addition of an array of arms to the left and right of the antenna and the addition of reflectors as a gain enhancer. The four antenna array units are combined using a power divider (combiner) as a unifying antenna. Antenna design with end fire radiation pattern cannot be used in receiving the ADS-B antenna system, because it works only in certain sectors with certain beamwidth, so it needs to be modified by adding an array of 4 units that make up 360◦ radiation of directional diagrams. The addition of the reflector is done by testing the optimum width. The most optimum width is obtained by the width of the side addition on the side of the antenna aperture cross section width of 80 mm. Based on the results of experiments that have been carried out for the design of receiver antennas for ADS-B applications that are required in the form of a radiation pattern in all directions using the reflector technique, the most appropriate gain increase is to use a phase difference for the antennas that are closest both left and right by 90o in ¼ λ conditions in the integration process using a 4 way power combiner. Response return loss at frequency 1.0752 GHz and 1.109 GHz is -15 dB, it means antenna has 33.8 MHz bandwidth with maximum response return loss at -23.22 dB and gain of 7.586 dBi, this antenna design is very suitable for use in the ADS-B application. Design and simulation at this antenna used CST software.

Published: December 2021

The electric motor is one of the technological developments which can support the production process. DC motor has some advantages compared to AC motor especially on the easier way to control its speed or position as well as its widely adjustable range. The main issue in the DC motor is controlling the angular speed with uncertainty and disturbance. The alternative solution of a control method with simple, easy to design, and implementable in a multi-input multi-output system is integral state feedback such as linear quadratic Gaussian (LQG). It is a combination between linear quadratic regulator and Kalman filter. One of the advantages of this method is the usage of fewer sensors compared with the original linear quadratic regulator method which uses sensors as many as the state in the system model. The design, simulation, and experimental study of the application of LQG as state feedback control in a DC-drive system have been done. Both performance and energy were analyzed and compared with conventional proportional integral derivative (PID). The gain of LQG was determined by trial whereas the PID gain is determined from MATLAB autotuning without fine-tuning. The load test and tracking test were carried out in the experiment. Both simulation and hardware tests showed the same result which LQG is superior in integral absolute error (IAE) by up to 74.37 % in loading test compared to PID. On the other side, LQG needs more energy, it consumes higher energy by 6.34 % in the load test.

Microwave imaging, such as images for radiological inspection in the medical profession, is one of the applications utilized in ultra-wideband (UWB) frequency ranges. The Vivaldi antenna is one of the most popular antennas for this purpose. The antenna is utilized because of its simple, lightweight, and compact design, as well as its excellent efficiency and gain capabilities. In this work, we present a high-gain Vivaldi antenna for microwave imaging applications. The proposed Vivaldi antenna is designed using a double-slot structure method with the addition of corrugated edges and a semicircle director aimed at improving the gain. The antenna is designed to operate at frequencies ranging from 3.1 to 10.6 GHz. Based on the modeling findings, the suggested antenna attain a bandwidth of 7.5 GHz with operating frequencies from 3.1 GHz to 10.6 GHz for a VSWR of less than two. In comparison to a typical single slot antenna, the suggested antenna provides a substantial boost in gain performance. The increase in gain is proportional to the frequency of operation. The constructed antenna has a lower bandwidth than the simulated one, with operating frequencies of 3.5 GHz – 3.75 GHz and 4.25 – 10.89 GHz, respectively, and useable bandwidths of 250 MHz and 6.64 GHz. All these results suggest that the antenna is suitable for microwave imaging applications.

Published: December 2021

Indonesia is rich in endemic species of flora and fauna. One of them is Ornithoptera croesus butterfly, which is endemic to North Maluku. Habitat degradation and trade of this species have caused the populations to decline. To avoid the collection of butterfly specimens from nature and to preserve their habitat and population in nature, a semi-natural butterfly breeding practice at Bacan Island was initiated in 2013. This research was conducted to assess the breeding approach for O. croesus lydius using a qualitative descriptive method. The assessment was based on these variables: the specific ecology of the butterfly; the suitability of the breeding site and development model; the utilization of larval host plants and butterfly nectar plants; and the establishment of the birdwing population at the site. The observations and results are presented here. Based on the assessment, the in-situ semi-natural breeding approach is one of the solutions for sustainable use of this protected species.

Published: December 2021

Troides helena and Pachliopta adamas utilize the same food plant species: Aristolochia acuminata. For the purpose of captive breeding and conservation, it is desirable to find out whether they can co-exist in captivity. Captive breeding research was conducted on the butterfly species within the period of October 2016 to September 2019. In total, 1,361 individuals were observed. Data on adult emergence of the species is presented to show population trends. Both species co-existed poorly at the facility when food plants were limited.  It took 45.9 days for T. helena helena and 32.6 days for Pc. adamas adamas from egg to imago stage. Habitat enrichment can encourage the species to come and establish the population.
DIVERSITY OF THE CLOSED-NESTED HONEY BEES (APIDAE: APIS SPP.) AND THE TRADITIONAL HONEY COLLECTING AND BEEKEEPING IN FOUR ISLANDS OF INDONESIA
Authors: Kahono Sih , Peggie Djunijanti , Sulistyadi Eko
Published: December 2021

The closed-nested honey bees are an important group that has been successfully bred traditionally and in a modern way. The traditional honey beekeeping practices are still favorable by local people living near natural habitats. Many rural areas in Indonesia are well known as producers of honey from the traditional honey collecting and traditional honey beekeeping of the closed-nested honey bees. However, there is limited information on the diversity of the honey bees that had supported the honey productions and their traditional honey beekeeping. This research was to provide an overview of the diversity of the honey bee species that are used in the wild honey collecting and their traditional honey beekeeping in four selected study sites in the islands of Java, Bawean, Kalimantan, and Peleng. We recorded three species of closed-nested native honey bees in the traditional honey collecting and traditional honey beekeeping, namely Apis cerana, A. koschevnikovi, and A. nigrocincta. We observed that traditional beekeeping of A. cerana was carried out in Tasikmalaya and Bawean Island, and that of A. cerana and A. koschevnikovi were carried out in Kayan Hilir. On Peleng Island, people do not do beekeeping but collect honey directly from the forest. Honey collecting and beekeeping practices are related to changes in the seasons of the flowering period in their habitats. The knowledge of the flowering period is needed to know the seasonal movement of honey bees from forest to village and vice versa.

carbonitrile (CPHPC) ligand and its 3d-metal(II) complexes has been synthesized (where [M = Co(II),
Ni(II) and Cu(II)]. The physico-chemical, analytical data, UV-Vis, FT-IR, 1H NMR and ESR spectrum
methods were used to characterize all of the synthesized complexes. Spectral investigations of metal(II)
complexes revealed that the metal ion is surrounded by an octahedral geometry. Low conductance
values indicated that the metal(II) complexes behave as non-electrolyte. The cytotoxic activity on
lung cancer cell lines and hepatic cancer cell lines A549 and HepG2, respectively, with the ligand and
their metal complexes were tested with MTT assay. The ligand and its metal complexes were tested
for diverse harmful bacterial strains using the agar well diffusion method on Gram-negative bacteria
such as Pseudomonas desmolyticum, Escherichia coli and Klebsiella aerogenes, as well as Gram-positive
bacteria Staphylococcus aureus.

were characterized by various spectroscopic and analytical techniques such as FT-IR, UV-Vis, 1H
NMR, 13C NMR, ESI-Mass, ESR, elemental analysis and magnetic susceptibility. Spectral data revealed
octahedral geometry for cobalt(II), nickel(II), copper(II) complexes and tetrahedral geometry for zinc(II)
complex. All the metal(II) complexes along with the Schiff base ligand were screened for their anticancer
activities. The CT-DNA binding studies revealed high binding propensity for metal complexes with
Kb values 1.50 × 104 M-1 for 1; 3.62 × 104 M-1 for 2; 2.53 × 104 M-1 for 3 and 1.8 × 104 M-1 for 4,
respectively. Anticancer studies against A549 & MCF-7 demonstrated excellent antiproliferative activity
with IC50 values in the range 17.62-48.82 μM. A standard drug cisplatin was employed to compare the
activity of metal complexes. The complexes exhibited remarkable antitumour activity due to their
high binding ability with DNA. It is interesting to observe that the complexes did not produce any
cytotoxicity towards the normal cell lines.

Human experts are integral to the success of computational earth observation. They perform various visual decision-making tasks, from selecting data and training machine-learning algorithms to interpreting accuracy and credibility. Research concerning the various human factors which
affect performance has a long history within the fields of earth observation and the military. Shifts in the analytical environment from analog to digital workspaces necessitate continued research, focusing on human-in-the-loop processing. This article reviews the history of human-factors
research within the field of remote sensing and suggests a framework for refocusing the discipline's efforts to understand the role that humans play in earth observation.
Examining the Integration of Landsat Operational Land Imager with Sentinel-1 and Vegetation Indices in Mapping Southern Yellow Pines (Loblolly, Shortleaf, and Virginia Pines)
Authors: Akumu Clement E. , Amadi Eze O.
Published: December 2021

The mapping of southern yellow pines (loblolly, shortleaf, and Virginia pines) is important to supporting forest inventory and the management of forest resources. The overall aim of this study was to examine the integration of Landsat Operational Land Imager (OLI ) optical data withSentinel-1microwave C-band satellite data and vegetation indices in mapping the canopy cover of southern yellow pines. Specifically, this study assessed the overall mapping accuracies of the canopy cover classification of southern yellow pines derived using four data-integration scenarios: Landsat OLI alone; Landsat OLI andSentinel-1; Landsat OLI with vegetation indices derived from satellite data—normalized difference vegetation index, soil-adjusted vegetation index, modified soil-adjusted vegetation index, transformed soil-adjusted vegetation index, and infrared percentage vegetation index; and 4) Landsat OLI withSentinel-1and vegetation indices. The results showed that the integration of Landsat OLI reflectance bands withSentinel-1backscattering coefficients and vegetation indices yielded the best overall classification accuracy, about 77%, and standalone Landsat OLI the weakest accuracy, approximately 67%. The findings in this study demonstrate that the addition of backscattering coefficients fromSentinel-1and vegetation indices positively contributed to the mapping of southern yellow pines.
EFEITO MODERADOR DA ALAVANCAGEM OPERACIONAL NA RELAÇÃO ENTRE INVESTIMENTO CORPORATIVO E RENTABILIDADE DA FIRMA

Published: December 2021

Objetivo: analisar de que forma a alavancagem operacional modera a relação entre investimento corporativo e rentabilidade de empresas listadas na B3.
Método: A amostra foi composta por 114 empresas ativas na B3. Para análise dos dados foi usada regressão com dados em painel compreendendo o período de 2008 a 2018. Foram usados modelos estáticos e dinâmicos, com estimação FGLS e PCSE.
Resultados: Os resultados principais mostraram que a alavancagem operacional modera a relação entre investimento corporativo e rentabilidade, de forma que quanto maior a alavancagem operacional e maior o investimento, maior a rentabilidade.
Contribuições: Fornecer evidências empíricas de que uma maior alavancagem operacional tem o potencial de aumentar a rentabilidade da firma não apenas quando do aumento nas vendas, mas também dependendo do nível de investimento corporativo no período anterior. A implicação é que uma maior alavancagem operacional é vantagem para empresas que apresentam oportunidade de crescimento e não atingiram o ponto de superinvestimentos. Uma explicação econômica para esse efeito foi a variação negativa no investimento (desinvestimento) em seis dos onze períodos analisados e períodos com quedas nas vendas, provavelmente devido às crises política e econômica vivenciadas, o que pode ter contribuído para que a maior AO promovesse o investimento ao invés de inibir, contrariando os achados de Jiao et al. (2019).

Slum settlement is one of the significant global problems which requires special concern in the discussion agenda of Sustainable Development Goals (SDGs) of 2016-2030. The Sustainable Development Summit held in New York in September 2015 formulated that one of SDGs goals is to build inclusive, safe, resilient, and sustainable cities and settlements. In Indonesia, the achievement of this goal is stated in National Medium-Term Development Plan 2015-2019, i.e. creating 0% urban slum settlement which is supported by policies expected to accommodate the achievement of national development targets. Semarang Mayor Decree No. 050/801/2014 concerning the Determination of the Location of Housing Environment and Slum Settlements in Semarang City has been issued as the basis to identify slum settlements scattered throughout Semarang city, in terms of location, physical condition, and social conditions. This study was conducted by case studies on slum settlements in Trimulyo Village and Mangkang Wetan Village, Semarang city, Central Java Province, Indonesia, to formulate a slum upgrading model based on the resilience level of coastal communities towards climate change. The analysis included identifying the characteristics of slum settlements, scoring analysis to determine the resilience level possessed by coastal communities, and analysis of pentagon assets used to formulate slum upgrading models. The results of the study showed that these two research areas had a moderate level of vulnerability, with several different characteristics of asset ownership, particularly those related to human and social assets. Increasing the quality of human resources and social relations in the community was more intensified in the environment and community in Trimulyo, while improving the physical quality of the environment through housing improvements was carried out in Mangkang Wetan.

Temperature Acquisition System for Real Time Application of First Velocity Correction by EDM (Electronic Distance Measurement)
Authors: Carvajal Rodriguez Felipe Andrés , Koenig Veiga Luis Augusto , Alcântara Soares Wilson
Published: December 2021

The first velocity correction is used to correct the measured distance affected by the velocity variation of the electromagnetic wave propagation in a medium. This correction depends on the refractive index of the propagation medium and reference refractive index. The influence of the temperature in the medium refractive index is critical; some estimates establish that variation 1°C causes 1ppm of error in distances. In the measuring processes with total stations, the temperature is usually collected at only one point, for example, in the position where the measuring instrument is setup. However, the wave propagates in a medium of non-constant temperature, where the extremes of the line can present variations and thus this measurement in only one point could be non-representative. In this context, it was developed a low-cost real-time temperature acquisition system. This system provides the temperature values in different locations allowing their monitoring through the time. Experiments realized during the geodetic monitoring of a dam, show variations up to 8°C among geodetic points on the dam and around it. An analysis was development to evaluate the influence of temperature variations on monitoring distances and geodetic coordinate of a 2d network with different approaches (temperature modeling).  The results shows different values for distances (1.0 mm) and coordinates (0.5 mm) depending of the approach choose.
Przez kwasową psychiatrię do kwasowego komunizmu. Renesans psychodeliczny w psychiatrii jako szansa na zmianę paradygmatu
Authors: Stupak Radosław
Published: December 2021

Mark Fisher wrote „the task of repoliticizing mental illness is an urgent one if the left wants to challenge capitalist realism.” This paper attempts to develop this thought and show how the repoliticization of issues defined as mental illnesses that could have an emancipatory potential and undermine capitalist realism could look like and how it could be related to the contemporary phenomenon of „psychedelic renaissance”. This repoliticization could constitute the first step towards acid communism – a step that would enable a comprehensive formulation of the project, the imagining of both acid communism itself as well as the road towards it. Even though psychedelics could provide an impulse for the change of the dominant psychiatric paradigm and the reorganization of mental health services, the process of the interception of these substances by the alienating and commodificating orders of psychiatry and capitalism can already be observed, so that both of the intertwined and mutually supporting orders can in fact be strengthened. From this perspective the institution of psychiatry becomes a key element preserving the status quo, which makes the imagining of the end of capitalism impossible. Politicization of mental health, that could question capitalist realism, needs to be connected with the deconstruction of the ideology of psychiatry.
Kwasowy komunizm. Nieukończone wprowadzenie
Authors: Fisher Mark , Kaczmarski Paweł
Published: December 2021

Artykuł stanowi nieukończone przez autora wprowadzenie do książki, którą zmarły filozof Mark Fisher projektował pod koniec życia i której nigdy nie napisał. Przedstawia w nim zarys koncepcji kwasowego komunizmu, czyli myślowej prowokacji wskazującej na potrzebę przemyślenia dziedzictwa kultury radykalnych ruchów lat 60. i 70., zwłaszcza istniejącego w nich napięcia między indywidualizmem a kolektywizmem. Istotną inspiracją myśli Fishera pozostają zwłaszcza prace Herberta Marcusego.
