Authors: Findik Ali , Pinarer Ozgun , Turhan Sultan
Published: January 2022

Central Sterilization Units (MSU) in our country are insufficient in terms of planning, operation, management, infrastructure design and technological aspects. This negatively affects the work of health institutions and causes the spread of hospital infections threatening public health. A business plan to be adopted throughout the country is standardized by supporting the operation processes of MSUs which have an important place in terms of the health of the health institutions in our work in terms of community health, with the technological infrastructure. In this report, a smart system model is presented in order to improve the productivity of the business processes belonging to the Central Sterilization Unit of health institutions and to improve their performance. With the new process model unveiled, standardization is realized in the processes applied in the MSUs. In this direction, firstly the functioning of the MSU of a medium-sized health institution was examined, the causes of the inefficiency in the current operation were determined, and a new process modelling was carried out to improve the system. In the second stage of the project, the center's productivity and performance changes were measured if an information system was included in the operation of the MS. Business processes and writing processes are reconfigured in line with the outputs obtained and made suitable for the health institution. In addition, with the barcode-optical reader system added to the information system, the error-free and efficient operation of the system has been ensured by minimizing the user interaction in line with the internet principles of the objects.

Published: January 2022

Microstrip reflectarray antennas (RAs) are able to provide equivalent performance of a traditional parabolic reflector, but with simple and light electromagnetic and mechanical structures; this can be achieved by an effective control of the phase response of each microstrip element on the reflecting surface. Thus the main problem is the fast and accurate modelling of the unit microstrip patch to be used in the array optimization. Since using simulators in the optimization procedure is computationally very ineffective, herein artificial intelligence is used as a rapid and accurate tool for characterization of the reflection angle of the microstrip unit element in terms of its geometry, substrate parameters and frequency. For this purpose, modelling of Omega shaped patch within the X-band is considered using Multilayer Perceptron (MLP) neural network trained the 3D CST microwave Studio simulator data. Validation of the MLP model is also worked out successfully with the 3D CST data. Thus a continuous function is obtained for the reflection angle in the geometry, substrate and frequency domain of the microstrip patch unit element that ensures the reflectarray optimization procedure as fast as using the analytical functions and as accurate as the 3D simulators. In the paper, full-wave simulation- based MLP modelling of the omega shaped microstrip patch is given in details.

Published: January 2022

In this study, a data set containing normal and different heart beat types recorded by the Massachusetts Institute of Technology-Beth Israel Hospital (MIT-BIH) was used for the detection of cardiac dysfunctions. In this data set, features were extracted using the LabVIEW Biomedical Workbench from the normal heartbeat and six different arrhythmia types. Obtained signals were evaluated by using Artificial Neural Network multiple classification method. Classification performances were compared before extracting the feature on the same data set. Classifier performances were evaluated by accuracy, sensitivity and selectivity performances criteria of classification. In the classifier performances, the "Normal" beat rate was found to be 99% accurate with the highest success compared to other arrhythmia types. As a result, both analysis methods are successful, but when the LabVIEW Biomedical Workbench is used, the classification results have achieved higher success.

Published: January 2022

Kondisi darurat yang diakibatkan oleh pandemi Covid-19 menuntut perlunya respon pemerintah, baik aspek kebijakan keuangan maupun pelaksanaannya secara cepat. Penelitian ini bertujuan untuk mengidentifikasi penerapan kebijakan keuangan dalam penanganan Covid-19 dan melakukan tinjauan terhadap siklus pelaksanaan anggaran belanja Pemerintah Daerah Kabupaten “ABC” untuk penanganan pandemi Covid-19. Pengumpulan data dilakukan melalui studi kepustakaan dan metode studi lapangan berupa wawancara serta observasi dalam pengumpulan data pada Badan Keuangan Daerah Kabupaten “ABC” untuk kemudian diolah dan dianalisis secara kualitatif dengan metode interaktif. Hasil penelitian menunjukkan bahwa kebijakan keuangan Pemerintah Daerah Kabupaten “ABC” terhadap pandemi Covid-19 terdiri atas percepatan refocusing/realokasi anggaran, dan rasionalisasi anggaran pendapatan, serta optimalisasi penggunaan belanja tidak terduga yang dianggarkan terpusat pada SKPKD. Rangkaian aktivitas yang dilakukan dalam siklus pelaksanaan anggarannya melibatkan PPKD dan pengelola kegiatan dan/atau keuangan pada SKPD yang terkait dengan penangan Covid-19. Tahapan dalam siklus hampir sama dengan proses belanja non penanganan Covid-19, tetapi berbeda dalam hal penyiapan penyesuaian dokumen pelaksanaan, dan percepatan dalam pencairan dana. Hasil penelitian dapat menjadi pembelajaran dalam mengantisipasi keadaan yang mendesak/darurat.
The emergency conditions caused by the Covid-19 pandemic require the government to respond, both in terms of financial policy and its implementation quickly. This study aims to identify the application of financial policies in handling Covid-19 and to review the implementation cycle of the "ABC" Regency Regional Government budget for handling the Covid-19 pandemic. Data collection was carried out through literature study and field study methods in the form of interviews and observations in data collection at the "ABC" Regency Regional Finance Agency to then be processed and analyzed qualitatively with interactive methods. The results showed that the "ABC" District Government's financial policy towards the Covid-19 pandemic consisted of accelerating budget refocusing/reallocation, and rationalizing the revenue budget, as well as optimizing the use of unexpected expenditures that were budgeted centered on SKPKD. The series of activities carried out in the budget implementation cycle involve PPKD and activity and/or financial managers at SKPD related to Covid-19 handling. The stages in the cycle are almost the same as the non-Covid-19 spending process, but differ in terms of preparing the adjustment of implementation documents, and in accelerating the disbursement of funds. The results of the research can be a lesson in anticipating urgent/emergency situations.

Co znaczy i co oznacza śmiech? O metonimicznych źródłach wieloznaczności czasownika śmiać się
Authors: BANASIAK DAGMARA
Published: January 2022

Artykuł wpisuje się w nurt badań nad walencją i semantyką polskich czasowników nawiązujących do
modelu struktur predykatowo-argumentowych autorstwa Stanisława Karolaka. Głównymi zadaniami
pracy są repartycja i opis znaczeń polisemicznego kształtu językowego śmiać się. Zebrany materiał badawczy
pokazuje, że predykat ten konstytuuje w polszczyźnie kilka różnych konstrukcji składniowych:
[ktoś] śmieje się, że_, [ktoś] śmieje się z [kimś] z tego, że_, [ktoś] śmieje się do [kogoś], [ktoś] śmieje się
z [siebie], że_, [ktoś] śmieje się z [kogoś/czyjegoś], że_, [ktoś] śmieje się z tego, że_, których struktury
formalne, semantyczne i pojęciowe są rezultatem rozszerzeń metonimicznych opartych na mechanizmie
polisemii radialno-łańcuchowej. Autorka podejmuje analizę procesów metonimicznych kształtujących
gniazdo leksykalne utworzone wokół czasownika śmiać się oraz zwraca uwagę na kwestię, jak za ich
sprawą do wtórnych znaczeń tego leksemu przenikają treści pochodzące ze sfery kultury.
What does laughter mean from a linguistic and extralinguistic perspective? On metonymy as a source of polysemy
of the Polish verb śmiać się (to laugh)
Summary: This paper investigates the main syntactic and semantic features of the Polish polysemous predicate śmiać
się (to laugh) within the theory of Semantic Syntax (Karolak 1984, 2002). The analysis shows that the verb
forms several predicate-argument structures, e.g.: 1) [ktoś] śmieje się z [kimś] z tego, że_, ([somebody]
laughs with [somebody] + SENT), 2) [ktoś] śmieje się do [kogoś] ([somebody] laughs to [somebody],
which means ‘to grin’), 3) [ktoś] śmieje się z [siebie], że_ ([somebody] laughs at [oneself] + SENT), 4) [ktoś] śmieje się z [kogoś/czyjegoś], że_ ([somebody] laughs at [somebody / something that belongs to somebody] + SENT), which are different in terms of the number, status and semantic roles of their arguments, reference and type of humour incorporated in the act of laughter. The source of this variety of meanings of the predicate śmiać się (to laugh) lies in metonymic extensions which fit into the pattern of radial and chain polysemy. The article also outlines how the semiotic (cultural) meaning of laughter is reflected in the semantics of the verb śmiać się (to laugh) through the mechanism of metonymy.

Published: January 2022

The Coronavirus disease 2019 (Covid-19) has led all countries around the world to the unpredicted situation. It is such a crucial to investigate novel approaches in predicting the future behaviour of the outbreak. In this paper, Google trend analysis will be employed to analyse the seek pattern of Covid-19 cases. The first method to investigate the seek information behaviour related to Covid-19 outbreak is using lag-correlation between two time series data per regional data. The second method is used to encounter the cause-effect relation between time series data. We apply statistical methods for causal inference in epidemics. Our focus is on predicting the causal-effect relationship between information-seeking patterns and Google search in the Covid-19 pandemic. We propose the using of Granger Causality method to analyse the causal relation between incidence data and Google Trend Data.
Seismic Anisotropy in the Northern Sumatra Region from Shear Wave Splitting
Authors: Candra Arya Dwi , Santosa Bagus Jaya
Published: January 2022

The northern Sumatra consists of several tectonic segments, such as subduction zone, the Sumatra and Mentawai faults. An analysis that can be used to identify the tectonic segments, located beneath the northern Sumatra, is shear wave- splitting. The purpose of the analysis of shear-wave splitting is to monitor the anisotropic characteristics of the structure of the earth layers located beneath the northern Sumatra. The monitoring data were collected from 4 BMKG stations with the magnitude was more than 6.3 Mw and the the range of the epicentral distance was about 85̊-140̊. The data analysis was conducted by using Splitlab program based on rotation-correlation method. The result of the shear-wave splitting analysis shows that there are two anisotropic layers. The delay time found in the first layer is about 0,5-0,9 s, which is assumed that it occurs due to the Sumatran fault. Meanwhile, the delay time found in the second layer is about 1,4-1,8 s, which is assumed that it occurs due to the subduction plate movement on the upper mantle layer. The results of TPTI, TSI and TRSI stations has shown congruence, that is the polarization direction is parallel to the Sumatra fault on the upper layer and the polarization direction is perpendicular to the Sumatra fault on the lower layer. The PSI station shows the polarization direction is different from the other stations, in which they show the polarization direction is perpendicular to the Sumatra fault on the upper layer and the polarization direction is parallel to the Sumatra fault on the lower layer. The difference of the data processing in the PSI station, we assume, is caused by the presence of a complex layer beneath Toba caldera.

Published: January 2022

Rayleigh-Taylor instability phenomena were encountered in science world, both on a small scale and large scale (interstellar gas). Rayleigh-Taylor instability is the interpenetration of material that occurs when a fluid is above the other fluid with smaller mass density. The fluid which was originally located in the upper part will continuously broke down and the void is filled by a fluid which was originally located in lower part, so it looks like a bubble. In computational fluid dynamic field, this phenomenon is one of the benchmarks used to test the performance of buoyancy force on a numerical method. On the particle method, particularly, the Rayleigh-Taylor instability has been successfully simulated using Moving Particle Semi-implicit (MPS) method. Similar to the MPS, on this study, the Rayleigh-Taylor instability between the silicon oil and water which driven by buoyancy force was simulated using finite volume particle (FVP) method. From the simulation results it can be concluded that the shape of the bubble produced in the present calculation is similar to the results observed in the experiments and methods of MPS.

Published: January 2022

In 2015, the Institute Teknologi Bandung (ITB) signed a Memorandum of Understanding with Sangyou Kyoto University (KSU). One realization of collaboration between ITB and KSU is observational program of Novae using a compact spectrograph NEO-R1000 (Novae and Emission line Objects with Resolution of 1000). This spectrograph is mounted at the Celestron C-11 (F/10.0) reflector and supported by a Losmandy G-11 equatorial mounting inside the GAO-ITB sliding roof building, Bosscha observatory, Lembang. The unique configuration of this spectrograph is the employment of mirror collimator and camera lens with focal length ratio of 3:1. This makes it has high speed characteristics. A slit width of 6.5 μm (4.7” @ C-11 reflector ) is combined with a fixed transmission grating of 600 grooves/mm and equipped with a ST-8 XME CCD camera (9 μm per pixel, 1530 × 1024 pixels), resulting in a resolution of R≈ 1000 at a wavelength of 5800 Å with effective spectrum wavelength coverage Δl 4000-8000 Å. NEO-R1000 spectrograph has additional peripherals such as a Fe-Ne-Ar hollow cathode tube (HTC) which is used as a comparison source. We take flat-field spectrum by using an acrylic board and a halogen lamp. The main primary aim of this spectrograph is to observe the Classical Novae in the southern sky as part of Collaborative Spectroscopic Observations for the Detection of Molecules in Classical Novae. This spectrograph can also be used to observe other emission line objects such as Planetary Nebulae, Comets, P Cygni star type, WR stars and Be stars. In June 2015, this spectrograph was successfully used to observe Nova Sgr 2015 no 2.

Further developments of this spectrograph includes constructing a rotator to be attached to the flange of telescope to ensure high flexibility in observation of extended objects. In the future, a fiber optic connecting output pupil with the entrance slit of the spectrograph will be deployed to improve observational effectivity while reducing the load of spectrograph on telescope.

Published: January 2022

The orbital dynamic of small objects is an n-body problem that can not be solve by analitically, it is needed to use numerical integration to find the solution instead. This work is about orbital dynamic of asteroid 1566 Icarus under Classical Newtonian gravitation and if thermal effect (Yarkovsky effect) is included. Yarkovsky Effect is a thermal radiation force resulted from time span of small rotating objects to receive heat from the Sun and then re-radiates it. The Yarkovsky Effect is working optimum for objects with diameter from 10 cm up to 10 km, and now is implemented to Asteroid 1566 Icarus with diameter 1.3 km which are member of Apollo and Earth crosser object. This Asteroid is called Earth crosser due to its orbit is crossing Earth’s orbit. With semi major axis a  1.078 au and eccentricity e  0.827, asteroid 1566 Icarus has perihelion distance q = 0.18674 au or less than semi major axis of Mercury. Due to that reason, Yarkovsky effect was considered to be applied on the orbital dynamics of asteroid 1566 Icarus. Due to sensitivity in input-data of numerical integration for n-body, one hundred simulation preliminary data were made as input in numerical integration process, therefore, 100 clones of Asteroid 1566 Icarus are gathered. Cloning process was conducted by using random number from Asteroid 1566 Icarus orbital elements at epoch 2456800.5 (23 May 2014) to standard deviation . The integration then later conducted within 105 years time span from the epoch. The result shown that the orbital dynamics of asteroid 1566 Icarus with Yarkovsky effect is still within the range of 100 clones of asteroid 1566 Icarus. Thereby, within 105 years, Yarkovsky effect does not change the orbital dynamic of asteroid 1566 Icarus globally, except for two phenomenon between close encounter with planet.

Published: January 2022

Surface deformation is a natural occurrence on the surface of the earth. The deformation can be in the form of subsidence or uplifting of the land surface. In this research, an time-lapse microgravity method will be applied to monitor surface deformation that occurs in Central Lombok and East Lombok Districts. The method of time-lapse microgravity is repetitive gravity measurement at the same point with a certain time interval, the measured magnitude is a change in the value of the acceleration of gravity and the microGal scale. Measurements were made in August 2016, April 2018, and June 2019. The measured value of the change in gravitational acceleration is the superposition of the changes caused by subsurface and surface sources. Separation of the two values is carried out using striping filter, which takes into account the ratio of density, thickness, and depth of the surface and subsurface layers. Land subsidence occurred during the period August 2016 to April 2018 and land uplifting occurred during the April 2018 to June 2019 period. This land subsidence occurred due to natural compacting and minor tectonic activity (small earthquakes that were not felt) while land uplifting was occurred due to major tectonic activities, in the form of the Lombok Earthquake in July to September 2018.

Authors: Rohiman Asep , Arifin Agus Saiful
Published: January 2022

The composition of chemical elements in rock samples can be used as a tool for classifying rock types, predicting the depositional environment, rock age, and the tectonic environment in which the rock is formed. X-Ray Fluorescence (XRF) is one of the instruments used to analyze rock samples. The advantage of using XRF analysis is that the analysis process can be done more quickly, easily, accurately, and does not damage the sample. However, before measurements are made using the XRF instrument it needs to be supported by an appropriate sample preparation process. In this study, optimal conditions in the standard (CRM) rock sample preparation of GBW 07105 and JR-1 have been studied. The parameters studied were variations in the composition ratio of Cellulose Mycro Crystalin (CMC) with standard (CRM) samples, namely 1: 4 and 1: 3. The technique of mixing the sample is done by using a mortar grinder and a shaker. Optimization of sample preparation was carried out using pressed powder pellet and fused glass bead techniques. Based on the data obtained from the analysis results the best ratio of binders to standard samples is 1: 3. The pressed powder pellet preparation technique is the best technique in analyzing samples using the X-Ray Fluorescence method. Further studies also need to be carried out to analyze minor elements and traces (REEs).

Authors: Fauzi Umar
Published: January 2022

The Lattice Boltzmann Method is one of the computational fluid dynamics methods that can be applied to simulate fluid based on the microscopic and kinetic theory of gases. In this study, earth mantle convection is simulated by combining the concept of lid-driven cavity simulation and natural convection using the Lattice Boltzmann method in a two-dimensional system (D2Q9). The results of the lid-driven cavity and natural convection simulation are comparable to previous works. This study shows that at a certain lid velocity, the direction of the moving plume is changed. This earth mantle convection simulation will give better and more reliable results by considering more complicated boundary conditions and adequate simulation systems.

Theoretical Equations for the Ratio of Undrained Shear Strength to Vertical Effective Stress for Normally Consolidated Saturated Cohesive Soils
Authors: Krisnanto Sugeng
Published: January 2022

Abstract
Two theoretical equations are developed to calculate the ratio of undrained shear strength to the vertical effective stress (the ratio of (su/sv’)) for normally consolidated saturated cohesive soils. The effective stress approach is used as the basis in the development of the theoretical equations. The theoretical equations are developed by relating the total and the effective stress paths. The development of the excess pore-water pressure is quantified using Skempton A and B pore-water pressure parameters. The theoretical equations are developed for two initial stress conditions: (i) an initially hydrostatic condition and (ii) an initially Ko (non-hydrostatic) condition. The performance of the theoretical equations of this study is compared with field and laboratory measurement data obtained from the literature. The close results between the theoretical equations and the measurements show that the theoretical equations of this study can compute the ratio of (su/sv’) well. Using the theoretical equations, the values of the ratio of (su/sv’) commonly used in engineering practice can be explained from the soil mechanics framework.
Keywords: Saturated cohesive soils, c/p ratio, normally consolidated soil, undrained shear strength, effective shear strength, theoretical equation.

Published: January 2022

Objective: Male genital tract infections have been associated with infertility, and Escherichia coli has drawn increasing attention as an important bacterium in this context. This investigation aimed to characterize and compare the distributions of O-antigen serogroups of E. coli in the semen samples of fertile and infertile men. Methods: In this case-control study, semen samples were collected from 618 fertile and 1,535 infertile men. The E. coli-positive samples were evaluated in terms of concentration, morphology, viability, and motility parameters according to the World Health Organization 2010 guidelines. Finally, different serogroups of E. coli were identified by multiplex polymerase chain reaction targeting the O-antigen variations of the bacterium.Results: The prevalence of E. coli among fertile men was significantly higher than among infertile men (p<0.001). The sperm morphology, viability, and motility in the E. coli-positive fertile group were significantly higher than in the E. coli-positive infertile group (p<0.001). E. coli O6 was the most prevalent serogroup found in both groups. However, there was no significant difference in the frequency of different serogroups of E. coil between the two groups (p=0.55). Conclusion: Despite the higher prevalence of E. coli among fertile men, E. coli had more detrimental effects on semen parameters in infertile men. There was no significant difference in E. coli serogroups between the fertile and infertile groups.

Objective: The present study was to investigate the extraction conditions of dietary fiber from dried cassava pulp (DCP) and cassava distiller’s dried grains (CDG) under different NaOH concentrations, and the Fourier transform infrared (FTIR) was used to determine the dietary fiber components.Methods: The dried samples (DCP and CDG) were treated with various concentrations of NaOH at levels of 2%, 4%, 6%, and 8% using a completely randomized design with 4 replications of each. After extraction, the residual DCP and CDG dietary fiber were dried in a hot air oven at 55°C to 60°C. Finally, the oven dried extracted dietary fiber was powdered to a particle size of 1 mm. Both extracted dietary fibers were analyzed for their chemical composition and determined by FTIR.Results: The DCP and CDG treated with NaOH linearly or quadratically or cubically (p< 0.05) increased the total dietary fiber (TDF) and insoluble fiber (IDF). The optimal conditions for extracting dietary fiber from DCP and CDG were under treatment with 6% and 4% NaOH, respectively, as these conditions yielded the highest TDF and IDF contents. These results were associated with the FTIR spectra integration for a semi-quantitative analysis, which obtained the highest cellulose content in dietary fiber extracted from DCP and CDG with 6% and 4% NaOH solution, respectively. The principal component analysis illustrated clear separation of spectral distribution in cassava pulp extracted dietary fiber (DFCP) and cassava distiller’s dried grains extracted dietary fiber (DFCDG) when treated with 6% and 4% NaOH, respectively.Conclusion: The optimal conditions for the extraction of dietary fiber from DCP and CDG were treatment with 6% and 4% NaOH solution, respectively. In addition, FTIR spectroscopy proved itself to be a powerful tool for fiber identification.

This paleochemical study explores the differences and similarities in weaning practices between two colonist populations buried in Montreal and its environs: the rural village cemetery of Pointe-aux-Trembles (PT, 1709–1843) and the urban Notre-Dame cemetery (ND, 1691–1796). Forty-six teeth (or individuals) were microsampled in both crown and root parts of the dentine (one to four and four to six sampling sites for deciduous and permanent teeth, respectively), totaling 56 microsamples for PT (seven M1, seven m1, and three m2) and 102 for ND (22 M1 and seven m1). For both sites, a general decrease of 1.3‰ in δ15N (ranging from 0.5‰ to 2.6‰) was observed between the first and last samples for permanent teeth (PT: five out of seven individuals; ND: 14 out of 22), and weaning seems to end around 2 years of age. As expected, in both parishes, weaning was mainly gradual (80%: PT; 86%: ND). An introduction of complementary food was also identified after 6 months of age (73%: PT; 81%: ND). The variation in δ15N profiles suggested other scenarios such as introduction of complementary foods just after birth (four PT and four ND), absence of breastfeeding (three PT and nine ND), and abrupt weaning (three ND). Environmental and socioeconomic factors might explain these individual variations, as infant feeding practices might have changed over time in these two growing and closely related parishes.
 
Cette étude paléochimique explore les différences et les similitudes dans les pratiques de sevrage entre deux populations de colons enterrées à Montréal et ses environs : le cimetière rural du village de Pointe-aux-Trembles (PT, 1709–1843) et le cimetière urbain de Notre-Dame (ND, 1691–1796). Quarante-six dents (ou individus) ont été micro-échantillonnées dans la dentine de la couronne et des racines (1 à 4 et 4 à 6 sites d'échantillonnage pour les dents de lait et les dents permanentes respectivement), totalisant 56 micro-échantillons pour PT (7 M1, 7 m1 et 3 m2) et 102 pour ND (22 M1 et 7 m1). Pour les deux sites, une diminution du d 15N d’une moyenne de 1,3‰ (allant de 0,5 à 2,6‰) a été observé entre le premier et le dernier micro-échantillon pour les dents permanentes (PT : 5 sur 7 individus ; ND : 14 sur 22), et le sevrage semble se terminer vers l'âge de deux ans. Comme attendu, dans les deux paroisses, le sevrage a été principalement progressif (80 % : PT ; 86 % : ND). Une introduction d'aliments complémentaires a également été identifiée après l'âge de six mois (73 % : PT ; 81 % : ND). La variation des profils des valeurs de δ15N permet également de suggérer d'autres scénarios tels que : l'introduction d'aliments complémentaires juste après la naissance (4 PT et 4 ND), l'absence d'allaitement (3 PT et 9 ND) et un sevrage abrupt (3 ND). Des facteurs environnementaux et socio-économiques pourraient expliquer ces variations individuelles, car les pratiques d'alimentation des nourrissons pourraient avoir changé au fil du temps dans ces deux paroisses en pleine croissance et étroitement liées.
Postmortem Animal Interference in an Indigenous Burial (Lanzarote, Canary Islands)

Published: January 2022

This article addresses the study of an indigenous burial at Mina Mountain (Lanzarote), dating from cal A.D. 1300 to 1402. Pre-European funerary contexts in Lanzarote are scarce, resulting in a particular historical situation for a population that lived on the island for at least 1,400 years, whose dead people and burial sites are virtually unknown. We analyze the available data on mortuary practices of the native population, adding a new example to the limited existing evidence. This is the first archaeological study carried out on the island that focuses on a funerary context, providing clear evidence for canine scavenging on a corpse placed in a pit and the subsequent rearrangement of the disarticulated skeletal remains in a secondary hollow. The study advances bioanthropological description and specific taphonomic data of bone modifications as evidence of the events that took place at the site, providing data to interpret this singular burial. In addition, the chronological framework,  together with the references of the narrative sources describing the Franco-Norman conquest of the island in 1402, allows us to propose a potential scenario explaining this unique site.

 

Se aborda el estudio de un enterramiento indígena en Montaña Mina (Lanzarote), datado entre el 1300-1402 d. C. Los contextos funerarios en Lanzarote son escasos, reflejando una situación histórica peculiar en la que no se conocen donde están los muertos de una población que arraigó en la isla durante 1400 años. En este trabajo se analiza la información disponible sobre las prácticas funerarias indígenas, aportando un nuevo caso al limitado repertorio de sitios mortuorios. Se trata del primer estudio arqueológico sobre un contexto funerario con claras evidencias de carroñeo. El enterramiento corresponde a una fosa en la que el cadáver fue alterado por la intervención de perros, lo que provocó una reubicación posterior de los restos humanos dentro de la misma fosa. A partir del análisis bioantropológico y tafónomico de las evidencias óseas se establece la secuencia de los hechos que allí tuvieron lugar. Asimismo, atendiendo al marco cronológico del entierro y la información recogida en las crónicas de la conquista normanda de la isla en 1402, se propone un posible escenario para le explicación de este caso único.
Peso, mídia e preconceito
Authors: Arruda Agnes de Sousa
Published: January 2022

O Jornalismo tem sido crucial ao oferecer à população brasileira informações apuradas sobre o Coronavírus em um contexto de negação da ciência por parte das autoridades públicas. Apesar disso, não está isento da reprodução de preconceitos, nem na cobertura da pandemia. Este trabalho demonstra a relação entre gordofobia e mídia, de forma geral, e cobertura jornalística de forma específica, uma vez que essa recorre aos estereótipos das pessoas gordas e seus corpos para falar sobre a Covid, o período de quarentena e a busca por uma vacina em suas pautas. Usa-se pesquisa bibliográfica, exploratória, netnográfica e análise de conteúdo, em uma proposta de monitoramento de cobertura jornalística e crítica de mídia com foco em saúde.
A epidemia de Zika Vírus pelo olhar da imprensa
Authors: Honorato Johanna Inácia , Goveia Fábio Gomes
Published: January 2022

Esse trabalho analisa as imagens que circularam durante a epidemia de Zika Vírus nos perfis de mídia dentro da rede social Twitter. Para tanto coletamos 6 milhões de publicações de março de 2015 a fevereiro de 2016, dos quais coletamos as imagens publicadas pelos principais perfis de mídia do Brasil entre 22/11/15 e 29/02/16. As 3.308 imagens resultantes foram estudadas a partir de método quali-quanti. A análise resultou nas seguintes categorias: Causa/vetor, Vítimas, Autoridades Oficiais e Cura. No estudo analisamos as duas primeiras, que equivale a 70% (2305) das imagens. Concluímos que a imprensa reforça a uma narrativa que culpabiliza a população pela epidemia, já que o mosquito é o maior vilão, desconsiderando questões como a falta de saneamento básico.

Published: January 2022

Na pesquisa que aqui consideramos, realizamos análise de conteúdo das notícias jornalísticas sobre neurociência de um jornal impresso de grande circulação no Brasil, a Folha de S. Paulo, em três períodos consecutivos entre 1986 e 2015. Observamos que de 12 categorias temáticas identificadas, nove delas evidenciaram os enquadramentos: “biologização do social” e/ou “criação de doentes crônicos”. A partir da análise dos resultados e de uma revisão da literatura, fizemos uma discussão sobre o papel da mídia e dos cientistas na construção do discurso e dos enquadramentos propostos, indicando a urgência em se promover uma maior aproximação entre esses atores.
A Retórica de Aristóteles e Perelman na propaganda eleitoral negativa
Authors: Tesseroli Ricardo , Panke Luciana
Published: January 2022

O presente trabalho se propõe a criar uma metodologia para categorização de argumentos para a classificação da propaganda eleitoral negativa, baseada nas técnicas argumentativas apresentadas por Chaïm Perelman e Lucie Olbrechts-Tyteca na obra Tratado da Argumentação: a Nova Retórica. Para isso, partimos dos conceitos clássicos de Retórica e Persuasão de Aristóteles, e de estudos a sobre Propaganda Eleitoral Negativa ou de Desqualificação para fazer uma ponte com a obra que trata da Nova Retórica. Desta forma, chegamos a classificação de dez técnicas argumentativas:  Argumento de autoridade; Comparação; Divisão do todo em partes; Exemplo; Grupo e seus membros; Inclusão da parte no todo; Justiça; Pessoa e seus atos; Probabilidade e do argumento baseado no Ridículo. Essas técnicas foram analisadas e adaptadas à análise da propaganda eleitoral com o intuito de colaborar e aprofundar os estudos em comunicação eleitoral e posteriormente aplicá-las às tentativas de desqualificação dos candidatos a seus adversários na propaganda eleitoral, entre elas no HGPE.
Construção social e mídia
Authors: Fabris Carolina
Published: January 2022

O social é construído através de processos mediados tecnologicamente e por infraestruturas de comunicação, o modo como o mundo social muda é fundamentalmente entrelaçado com a mídia. Este artigo, tendo esse princípio como pano de fundo, faz uma revisão de autores que já exploraram as mudanças no capitalismo, como essas mudanças representam alterações na gestão das empresas e como isso é evidenciando em uma mídia específica, a mídia de negócios. Como objeto de análise, é explorado a revista HSM Management através das capas e dos editoriais de 4 edições. Os resultados evidenciam a relação da mídia e do social, da mídia de negócios brasileira e americana, o reforço de determinadas práticas a partir de um discurso pregado por “gurus” e como algumas mudanças na gestão, que representam mudanças de capitalismo, aparecem nesses materiais.
Citizens and the European Union since 1950
Authors: KAELBLE Hartmut
Published: January 2022

The article covers the relationship of the citizens with the European Union and its predecessors since the beginnings of the European integration in the 1950s. It dis­tinguishes the period of the unquestioned citizen during the 1950s and 1960s, the period of the questioned and mobilized citizen since the 1970s and the period of the active citizen since around the turn the of century, in looking at European elec­tions, referendums, European movements, interest organizations, regular European opinion polls, complaints by citizens at the European Parliament, at the European Commission and at the European ombudsman and legal proceedings by citizens at the European Court in Luxemburg. In addition, the article looks at the change be­tween periods of trust and periods of distrust by citizens in the European institu­tions since the 1950s. It argues that the trend towards the mobilized and active citi­zen includes an eventual strong rise of distrust in periods of crisis, but also by a return of trust by the citizens even in difficult periods such as the recent Covid19 pandemic.
