Avaliação do poder adsortivo da palma forrageira (opuntia tuna mill) para uso em remoção de contaminantes hidrogenocarbonados em copos d'água.
Authors:   , Tavares Débora
Published: July 2023

Compostos orgânicos tais como óleos lubrificantes, são poluentes de difícil degradação e liberados constantemente em efluentes como resultado de diversas atividades industriais. A adsorção é uma das operações unitárias que tem apresentado eficiência na remoção deste tipo de contaminante dos efluentes. A busca por adsorventes de menor custo tem apresentado as biomassas vegetais como opções eficientes, econômicas e sustentáveis. O objetivo deste trabalho foi avaliar a eficiência adsortiva da biomassa palma forrageira (Opuntia tuna Mill), obtida a partir de dois processos de secagem convectiva (secagem em secador de leito fixo e secagem natural), quando utilizada para remoção de óleo lubrificante usado ou contaminado presente em águas de descarte de lava-jatos automotivos. Na metodologia utilizada, para a obtenção da biomassa na forma particulada, após cada etapa de secagem, a palma passa por cominuição à forma de pó para seleção granulométrica das partículas. Seguiu-se com o estudo da cinética de adsorção, em que foram avaliados os tempos de 5 a 60 minutos (com intervalos de 5 min.) e o equilíbrio, cujas concentrações de contaminante variaram de 5 a 60% (com taxa de variação de 5%). Como resultado observou-se que a cinética de adsorção foi rápida, com a eficiência adsortiva sendo maior nos primeiros minutos do experimento para a palma obtida por meio dos dois processos de secagem. O equilíbrio foi alcançado, com valores de adsorção baixos e próximos entre si. A isoterma de Langmuir ajustou-se melhor aos dados de adsorção da palma seca ao natural. O maior valor de adsorção de contaminante obtido a partir da palma seca a 70°C foi 4,164 g.g-1. Para a palma seca ao natural a maior quantidade foi de 3,865 g.g-1 no equilíbrio. Portanto, os dois processos de secagem podem ser utilizados para obtenção de palma forrageira para uso como adsorvente. A palma caracteriza-se como uma importante alternativa para remoção de contaminantes de efluentes com baixas concentrações de óleo lubrificante contaminado.

Den politiska visionens retorik
Authors: Viklund Jon
Published: July 2023

Artikeln diskuterar visionens retorik i samtida svensk politik. Visionen är en viktig samtida politisk diskurs där partier formulerar hur de vill att framtiden ska se ut, med utrymme för såväl konkreta politiska mål som mera abstrakta ideella värden. Som exempel analyseras den svenska regeringens projekt Sverige – det nya matlandet, en vision om att Sverige ska bli Europas ledande matnation, ett mål som i reella politiska termer i första hand handlar om att gynna företagsamheten i livsmedelsektorn och att skapa nya jobb. Visionen lanserades av landsbygdsministern Eskil Erlandsson 2008. Artikeln analyserar visionens uppkomst och lansering, dess argumentation och konceptuella utformning. Analysen lyfter fram den visionära diskursen som en form av symbolisk handling varigenom kommunikationen blir ett sätt att förverkliga visionen.
Retorisk rekonstruksjon av politisk diskurs
Authors: Sandvik Margareth
Published: July 2023

Den offentlige, medierte debatten har en etablert posisjon i valgkampen, og særlig tv-debattene trekker seere. Om det er disse debattene som mobiliserer velgerne til å bruke stemmeretten på valgdagen, skal det ikke spekuleres i, men valgdeltakelsen i Norge er synkende, og bekymringen økende for at store deler av befolkningen ikke deltar ved valget. Dette er bakgrunnen for å spørre seg om valgkampdiskursen fungerer etter sin hensikt, nemlig å mobilisere velgere og opplyse dem om partipolitiske kampsaker og skillelinjer. Denne formuleringen av valgkampdiskursens hensikt, vil fungere som en vurderingsnorm i en retorisk analyse av valgkamp sendinger. Artikkelen henter eksempler fra norsk valgkamp i perioden 1991-2009.
Argumentationens retning. Direction of fit som definerende perspektiv på retorisk argumentation
Authors: Bommelund Houby Johan
Published: July 2023

Direction of fit – det sprogfilosofiske begreb for ytringers forhold til den omgivende virkelighed – undersøges i denne artikel som et muligt defi - nerende perspektiv på retorisk argumentation. Standpunktet er at det er muligt at identificere retoriske momenter i en given argumentation ved at se på tekstens overordnede direction of fit (Searle). Dette eksemplificeres ved en kort analyse af Putins Krim-tale fra 18. marts 2014, der som et klart eksempel på deliberativ retorik kan bruges til at vise hvordan ytringer på lokalt plan kan adskille sig fra talens samlede argumentative orientering. Hernæst diskuteres ideen i forhold til andre definerende perspektiver med Kocks domænebaserede definition som udgangspunkt. Målet er at etablere et argumentationssyn der afspejler den praktiske argumentations dynamik. Fokus rettes væk fra teoretisk orienterede definitioner og hen mod et mere praksisorienteret udgangspunkt.
Derfor skal du læse denne artiklen
Authors: Nygaard Blom Jonas , Reinecke Hansen Kenneth
Published: July 2023

I denne artikel kortlægges og analyseres de stilistiske greb, journalister bruger for at vække læsernes interesse på nettet. Her er konkurrerende historier kun et gratis klik væk, og rubrikkens form bruges derfor i udtalt grad til at fange og fastholde læserne. Analyserne viser, at journalister bruger en bred vifte af retorisk-stilistiske virkemidler for at pirre nysgerrigheden, bryde forventningen, aktivere forestillingsevnen og stimulere symmetrisk tænkning. Nogle af grebene er gamle kendinge fra antikke beskrivelser af ornatus, andre er nyere og mere mediespecifikke, heriblandt kataforer, der skaber spænding ved at tilbageholde information. Artiklen positionerer sig normativt ved kritisk at diskutere konsekvenserne af en sådan sproglig strategi, der sælger historien ved at sløre indholdet i rubrikken. Samtidig fremhæves en række fyndige alternativer, hvor rubrikkens form fremmer forståelsen og lever op til retorikkens klassiske stildyder, virtutes elocutionis.
Velkomst og afstandtagen – Ethos, humor og retoriske manøvrer når ordet gives videre
Authors: Barnholdt Hansen Jette , Isager Christine , Rønlev Rasmus
Published: July 2023

At introducere en taler er en så konventionel retorisk opgave inden for den epideiktiske genre, at den er tilbøjelig til at blive overset både i retorisk teori og kritik. Netop den høje grad af konventionalisering gør imidlertid, at formatet ofte udfordres i retorisk praksis på måder, der fortjener kritisk opmærksomhed. Med særligt fokus på humor og fremførelse undersøges det, hvordan introducerende værter og introducerede retorer forhandler og fordeler ethos i relation til deres publikum, når de henholdsvis giver og tager ordet. Et ældre og to mere aktuelle eksempler analyseres: Biskop Lovis Henry Ford, der som vært for præsident Bill Clinton i Memphis Church of God in Christ, USA, i november 1993 lægger kimene til en særligt kraftfuld tale; dernæst danske Radio24syvs kanalchefer Michael Bertelsen og Mads Brügger, der agerer ubehjælpsomme værter for viljestærke medarbejdere i en prisbelønnet reklamekampagne; og endelig komikeren Ricky Gervais, der som vært ved uddeling af Golden Globe-filmpriserne bryder eklatant med sin værtsrolle ved at ekskludere de talere, han introducerer, frem for at byde dem velkommen. Tilsammen illustrerer analyserne introduktioners store retoriske potentiale som anledning til retorisk manøvrering i Kendall Philllips’ forstand; det tilsyneladende så trivielle ritual kan tjene til midlertidigt at destabilisere en talesituation og åbne op for refleksion og forhandling af et fællesskabs selvforståelse.
Debatt om lederlønn i egalitære mediesamfunn
Authors: Ihlen Øyvind , Lie Einar
Published: July 2023

Toposteori gir gode verktøy for både å forstå og utøve virksomhets­retorikk. I denne artikkelen poengteres hvordan slik retorikk må ta hensyn til doxa og ikke minst arenaen som en eventuell debatt utspiller seg på. Gjennom en caseanalyse av en debatt om lederlønn viser vi hvordan noen topoi er vanskeligere å få gjennomslag for enn andre. I et egalitært samfunn vil ikke topoi hentet fra økonomisk teori ha like gode kår som topoi som tar utgangspunkt i likhet, moral og rettferdighet. Når debatten dessuten utspiller seg på mediearenaen, blir de sistnevnte topoi enda ­viktigere.
Känslans platser. Topikerna för pathos i Aristoteles Retoriken
Authors: Lindqvist Janne
Published: July 2023

Vår förståelse av Aristoteles Retoriken är på många sätt stympad. I synnerhet gäller det analysen av de specifika topikerna för pathos som utgör en stor del av textens andra bok. Trots att denna är nästan dubbelt så omfattande som analysen av de allmänna topikerna har den nästan inte intresserat tidigare forskare – i varje fall inte som exempel på just topiker – och de som sökt en förståelse för topikerna som sådana har ofta förbigått de känslomässiga topikerna med tystnad. Syftet med denna artikel är att lägga grunden för en sådan undersökning. Resultatet är först en distinktion mellan två typer av specifika topiker som här ges beteckningen schematiska respektive konkreta specifika topiker. Med utgångspunkt i dessa urskiljs tre generella topiker för pathos: subjekt, stimulus och agent. Dessa tre känslomässiga topiker är – om analysen är riktig – lika användbara på väg in i 2000-talets tredje decennium som de var i 400-talets Aten.
Den populistiske retoriks potentiale. En undersøgelse af Donald Trumps valgkampagne 2016

Populistiske bevægelser har succes i Vesten, mens etablerede partier og institutioner som menneskerettighedskonventioner, frihandelsaftaler, EU og NATO bliver dyrket som folkelige fjendebilleder. Men hvad er populisme, og hvad kendetegner populistisk retorik? Gennem en læsning af Donald Trumps valgkampagne og de samtidige reaktioner på den udvikler denne artikel en topik over den populistiske retoriks kendetegn, herunder den populistiske retoriks særlige potentiale for at skabe uforudsigelig retorisk agency.
Retorisk konstituering af en sag. Den græske tradition
Authors: Madsen Carsten
Published: July 2023

Denne artikel forfølger Maurice Charlands antagelse om, at modellen for konstitutiv retorik kan spores tilbage til sofisterne. Gennem en fremstilling af de væsentligste begrebslige og ontologiske sammenhænge mellem logos, tale, og eris, strid, er hensigten at vise, hvordan talen om fred og konflikt er underordnet en definition af retorik som den kunst at konstituere en sag. Artiklen henviser til Hesiod, Heraklit, Protagoras, Gorgias og Aristoteles og søger gennem inddragelse af Heidegger, Gadamer og Grassi at løsne retorik fra den almindelige forståelse, at den skulle være rettet mod en sag som noget på forhånd givet. Det er på den baggrund målet at uddybe Charlands redegørelse for den konstitutive retoriks konstruktion af et “folk” som en historisk bestemt identitet ved at klargøre, hvordan en konstitueret sag beror på tilsløringen af en forudgående konstituerende strid, og kort vise, at en retorik om “folkets sag” blot er et særtilfælde af konstitutiv retorik.
Hovets sofister: Diplomati, retorik och representationens problem
Authors: Stagnell Alexander
Published: July 2023

Retoriken och diplomatin delar något vi kan kalla representationens problem och som springer ur svårigheterna att någonsin på ett korrekt sätt representera någonting. Föreliggande artikel tar sig an detta gemensamma problem genom att undersöka de olika lösningar som erbjudits genom historien, något som tar oss från Platons och Aristoteles kritik av sofisterna, via Demosthenes och Aeschines ansträngningar att mäkla fred med Filip den II av Makedonien, till Rousseau, Kant och det samtida studiet av diplomatisk retorik. I Kants idé om den eviga freden och Perlmans begrepp om det universella auditoriet finner vi också något som framstår som modernitetens svar på detta antika problem, accepterandet av vad vi med Hegel skulle kunna kalla språkets och fredens dåliga oändlighet. Slut ligen diskuterar artikeln Lacans förståelse av diplomaten som representant och de möjligheter som erbjuds att undkomma den oändliga dialektiken mellan försöket och dess misslyckande.
Att göra många till en – om populismens logik
Authors: Lalér Theodor , Sundby Martin
Published: July 2023

Den här artikeln introducerar Ernesto Laclaus teori om populism för den skan-dinaviska retorikforskningen i syfte att adressera en beﬁntlig brist på begrepps liga resurser för att analysera populistiska artikulationer. Laclaus teori om populism syftar till att förklara de retoriska processer inneboende i varje politisk kamp såväl som att förstå konﬂiktdimensionen som konstitutiv för demokratisk politik som sådan. Detta perspektiv på populism är relevant för retorikforskare intresserade av politisk retorik i allmänhet eftersom den popu-listiska logiken – att göra många till en – genomkorsar själva essensen av det politiska. Därmed kan Laclaus perspektiv användas för att analysera en myriad av politiska fenomen och praktiker, inte enbart de som antas beﬁnna sig i poli-tikens ytterkanter. Artikeln består av tre delar. För det första, en litteratur -genomgång av populismstudier, för det andra en presentation av Laclaus populismteori och, för det tredje, en exempelanalys som illustrerar använd-ningen av teorins begrepp
Antimilitaristisk retorik og metaforisk transcendens – Viggo Hørup og Carsten Jensens kritik af dansk krigspolitik.
Authors: Roer Hanne
Published: July 2023

Artiklen belyser dansk antimilitaristisk retorik med eksempler fra journalist og politiker Viggo Hørup og forfatteren Carsten Jensen. Hørup kæmpede i slutningen af 1800-tallet mod en militaristisk politik der var grundlaget for Estrup-regeringens konstante indskrænkninger af den demokratiske forfatning fra 1848 (hvorved kong Christian IX ﬁk fornyet magt). Jensen har i ﬂere årtier kritiseret dansk kulturliv, fremmedfjendskhed og, siden 2003, dansk deltagelse i krigene i Afghanistan og Irak. Både Hørup og Jensen er eksempler på dissident-retorik, retorik der søger at nedbryde stivnede modsætningspar og afsløre manipulerende argumentation. Robert Ivies teori om dissident-strategier og metaforiske taktikker anven-des i analysen af Hørup og Jensens metafortunge retorik, der trods mere end 100 års tidlig afstand minder slående om hinanden. Det skyldes at de begge søger at nedbryde og ombryde en dikotomisk argumentation i en re-approprierende bevægelse. Hvor kritikernes modsvar på militaristiske strategier minder ganske meget om hinanden, har krigen fuldstændig ændret karakter; dette kommer til udtryk i Jensens roman Den første sten fra 2015.
‘How dare you!’ – anklager og mot-anklager på Facebook knyttet til Greta Thunbergs FN-tale 23. ­september 2019
Authors: Elgesem Dag , Kronstad Felde Andrea
Published: July 2023

I dette bidraget analyserer vi anklager på offentlige Facebook-sider i Danmark, Norge og Sverige i tilknytning til Greta Thunbergs tale i FN 23. september 2019. Disse anklagene er av tre typer: 1. anklager som forsterker og gjentar Thunbergs anklage i FN-talen, 2. anklager mot Thunberg og hennes støttespillere, 3. anklager mot dem som hetser Thunberg og hennes tilhengere på nettet. Ingen av anklagene er imidlertid det første trekk i en apologetisk diskurs. Vi argumenterer for at de retoriske funksjonene til slike anklager har to sentrale kjennetegn: 1. de tildeler ansvar til den som anklages gjennom å uttrykke en reaktiv holdning til ham eller henne, 2. anklagene uttrykker en vurdering av at den anklagede har gjort noe klanderverdig. Vi analyserer Facebook-anklagene knyttet talen til Thunberg i dette perspektivet, og karakteriserer de ulike retoriske funksjonene til de tre typene av anklager i materialet
En medieprovokatør bliver til: Personakonstruktioner og -transformationer i Eva Selsings retorik
Authors: Bengtsson Mette , Rønlev Rasmus
Published: July 2023

Med begrebet medieprovokatør, en personificering af Olivier Driessens’ begreb medieprovokation, peger vi på debattører, der i kraft af provo­kerende retorik og cirkulation på sociale medier opnår en prominent taleposition i traditionelle, journalistiske massemedier. I en nærlæsning af tre udvalgte tekster af Eva Selsing, som vi opfatter som en paradigmatisk case, viser vi, hvordan Selsing konstruerer og transformerer sin provo­kerende persona på tværs af journalistiske genrer og dermed etablerer sig som medieprovokatør i et hybridt mediesystem. På den baggrund disku­terer vi, hvordan provokerende stil kan fungere som en katalysator for retorisk handlekraft for medieprovokatører, de medier, de arbejder for, og potentielt den bredere offentlighed. Offentlighedens handlekraft er dog, som vi ser det, afhængig af, at publicistiske medier ikke blot tilbyder medieprovokatører en platform og bestyrker provokatørernes selv­iscenesættelse; publicistiske massemedier må også tage ansvar for og ­spille en aktiv rolle som kuratorer af den debat, der opstår i kølvandet på medie­provokatørernes retorik.

Simulation-Based Origin-Destination Matrix Reduction: A Case Study of Helsinki City Area
Authors: Bochenina Klavdiya , Taleiko Anton , Ruotsalainen Laura
Published: July 2023

Estimation of a travel demand in a form of origin-destination (OD) matrix is a necessary step in a city-scale simulation of the vehicular mobility. However, an input data on travel demand in OD matrix may be available only for a specific set of traffic assignment zones (TAZs). Thus, there appears a need to infer OD matrix for a region of interest (we call it ‘core’ area) given OD matrix for a larger region (we call it ‘extended’ area), which is challenging as trip counts are only given for zones of the initial region. To perform a reduction, we explicitly simulate vehicle trajectories for the extended area and supplement trip values in ‘core’ TAZs based on the recorded trajectories on the border of core and extended areas. To keep validation results consistent between extended and core simulations, we introduce edge-based origin-destination assignment algorithm which preserves properties of traffic flows on the border of the core area but also keeps randomness in instantiating simulation for the core area.
The experimental study is performed for Helsinki city area using Simulation of Urban MObility (SUMO) tool. The validation was performed using DigiTraffic data from traffic counting stations within the city area for workdays of autumn 2018. Validation results show that the reduced OD matrix combined with edge-based OD assignment algorithm keeps the simulated traffic counts in good agreement with results from the extended area simulation with average MAPE between observed and simulated traffic counts equal to 34%. Simulation time after reduction is equal to 20 minutes compared to 6 hours for the extended OD.
Development, Calibration, and Validation of a Large-Scale Traffic Simulation Model: Belgium Road Network
Authors: Bamdad Mehrabani Behzad , Sgambi Luca , Maerivoet Sven , Snelder Maaike
Published: July 2023

Development of large-scale traffic simulation models have always been challenging for transportation researchers. One of the essential steps in developing traffic simulation models, which needs lots of resources, is travel demand modeling. Therefore, proposing travel demand models that require less data than classical travel demand models is highly important, especially in large-scale networks. This paper first presents a travel demand model named as probabilistic travel demand model, then it reports the process of development, calibration and validation of Belgium traffic simulation model. The probabilistic travel demand model takes cities' population, distances between the cities, yearly vehicle-kilometer traveled, and yearly truck trips as inputs. The extracted origin-destination matrices are imported into the SUMO traffic simulator. Mesoscopic traffic simulation and the dynamic user equilibrium traffic assignment are used to build the base case model. This base case model is calibrated using the traffic count data. Al-so, the validation of the model is performed by comparing the real (extracted from Google Map API) and simulated travel times between the cities. The validation results ensure that the model is a superior representation of reality with a high level of accuracy. The model will be helpful for road authorities, planners, and decision-makers to test different scenarios, such as the im-pact of abnormal conditions or the impact of connected and autonomous vehicles on the Belgium road network.
Coping with Randomness in Highly Complex Sys-tems Using the Example of Quantum-Inspired Traffic Flow Optimization
Authors: Haberland Maria , Hohmuth Lars
Published: July 2023

Developing new solutions to complicated large-scale problems typically requires large-scale numerical simulation. Therefore, traffic simulations often run against randomized simulations instead of real-world traffic situations. This paper demonstrates a method to calculate the statistical significance of numerical simulations and optimizations in the presence of numerous random variables in complex systems using one-sided paired t-tests. While the paper covers a specific Fujitsu traffic-optimization project which uses SUMO for simulating the traffic situation, the method can be applied to many similar projects where a complete investigation of the solution space is not feasible due to the size of the solution space.
Technical Concept for sensor-based Traffic Flow Optimization on connected real-world intersections via a SUMO Feature Gap Analysis
Authors: Trautwein Ingo , Freymann Andreas , Reichsöllner Emanuel , Schöps Kraus Jessica , Sonntag Mirco , Schrodi Thomas
Published: July 2023

Traffic within cities has increased in the last decades due to increasing mobility, changing mobility behavior and new mobility offerings. These accelerating changes make it increasingly difficult for responsible authorities or other stakeholders to predict mobility behavior, to configure traffic rules or to size roads, bridges and parking lots.
Traffic simulations are a powerful tool for estimating and evaluating current and future mobility, upcoming traffic services and automated functionalities in the domain of traffic management. For being able to simulate a complex real-world traffic environment and traffic incidents, the simulation environment needs to fulfill requirements from real-world scenarios related to sensor-based data processing. In addition, it must be possible to include latest advancements of technology in the simulation environment, for instance, (1) connected intersections that communicate with each other, (2) a complex and flexible set of rules for traffic sign control and traffic management or a well-defined data processing of relevant sensor data. In this paper we therefore define requirements for a traffic simulation based on a complex real-world scenario in Germany. The project addresses major urban challenges and aims at demonstrating the contribution that the upcoming 5G mobile generation can make to solving real-time traffic flow optimization.
In a second step, we investigate in detail if the simulation environment SUMO (Simulation of Urban Mobility) fulfills the postulated requirements. Thirdly, we propose a technical concept to close the gap of the uncovered requirements for later implementation.
SUMO Simulations for Federated Learning in Communicating Autonomous Vehicles
Authors: Alekszejenkó Levente , Dobrowiecki Tadeusz
Published: July 2023

In transportation, a vehicle's route is one of the most private information. However, to mutually learn some phenomena in a city, for example, parking lot occupancies, we might have to reveal information about it. In this paper, we focus on assessing the privacy loss in a vehicular federated machine learning system. For the analysis, we used the Monaco SUMO Traffic Scenario (MoST). We also used the simulation inputs as statistical data to calculate privacy loss metrics. Results show that a vehicular federated machine learning system may pose a smaller privacy threat than individual learning, but its performance is lower compared to a centralized learning approach.
Due to the vast amount of data and processing time, we also describe a method to build a Docker image of SUMO together with a software client-server architecture for SUMO-based learning systems on multiple computers.
Generating and Calibrating a Microscopic Traffic Flow Simulation Network of Kyoto
Authors: Keler Andreas , Sun Wenzhe , Schmöcker Jan-Dirk
Published: July 2023

Microscopic traffic flow simulations as tools for enabling detailed insights on traffic efficiency and safety gained numerous popularity among transportation researchers, planners and engineers in the first to decades of the 21st century. By implementing a test bed for simulation scenarios of complex urban transportation infrastructure it is possible to inspect specific effects of introducing small infrastructural changes related to the built environment and to the introduction of advanced traffic control strategies. The possibility of reproducing present problems or the transportation services, such as the ones of public bus services is a key motivation of this work. In this research, we reproduce the road network of the city of Kyoto for observing specific travel patterns of public buses such as the bus bunching phenomena. Therefore, a selection of currently available data sets is used for calibrating a cutout of the Kyoto road network of a relatively large extent. After introducing a method for geodata extraction and conversion, we approach the calibration by introducing virtual detectors representing present inductive loops and make use of historical traffic count records. Additionally, we introduce bus routes partially contributed by volunteer mappers (OSM project). First simulation outcomes show numerous familiar (local knowledge) flow patterns.

Analisis Fundamental untuk Memperoleh Nilai Wajar Saham SMDR dengan Metode Free Cash Flow to Equity dan Price Earning Ratio
Authors: Yauwanta Yudha Suntara
Published: July 2023

Investors or parties who invest in shares, so far have faced obstacles in assessing the fair price of the stock to be purchased. The main cause lies in the limited knowledge or insight in conducting basic or fundamental analysis of the stocks to be purchased. The consequences that are often experienced are investing overvalued, price distortions, rushing to sell back shares so that the investment does not get optimal results. The objective of this paper contributes to analyze the fairness of SMDR's stock (PT. Samudera Indonesia, Tbk.) using the Free Cash Flow To Equity (FCFE) method and the Price Earning Ratio (PER) method, assuming constant economic growth and calculating intrinsic value using a comparison of the two methods. This research is a descriptive study using a quantitative approach. The object of this research is the stock of PT. Samudera Indonesia, Tbk (SMDR). In analyzing, the author will make a financial model with projections for the next 10 years and compare it with the current share price, to find out whether the company's shares (SMDR) are considered fairvalued, undervalued or overvalued. The use of FCFE will be more prominent as of this writing, using a discounted cash flow valuation framework. This research in the form of a fundamental analysis of SMDR shares will be conducted based on published audited financial reports for the years 2016 – 2021. The theoretical benefit of this research is to assist investors in assessing a company's shares, using the FCFE method, in determining investment decisions (buy/hold/sell).

Published: July 2023

In the past five years, people are becoming more accustomed to online purchases especially due to health measures taken as a response to the 2020 pandemic. Indonesia led all other ASEAN countries in terms of online purchases. In this study, we examined the relationship between external stimuli and impulse buying behaviour on e-commerce platforms. We conducted an online survey and found that quality of information, and e-wallet use have a positive influence on driving impulsive buying behaviour. For e-commerce business owners, these findings are helpful to determine areas to focus on when improving e-commerce. The theories underlying this research are Technology Acceptance Model Modified I introduced by Venkatesh and Davis (1996) and the concept of Impulse Buying Behavior by Gulfraz et al (2022). The research design was mainly developed from previous research by Kimigiari and Malafe (2021).

Published: July 2023

Indonesia is one of the countries that has carried out personnel reform by implementing open recruitment and selection for Primary High Leadership Positions (JPT) which are currently being carried out openly using a merit system. The National Archives of the Republic of Indonesia as a non-ministerial government institution has also implemented this policy in conducting open recruitment and selection by implementing a merit system. The purpose of this study is to analyze how the implementation of and problems with policy implementation in filling recruitment and open selection for Primary High Leadership Positions (JPT) in personnel management in Indonesia, especially in the National Archives of the Republic of Indonesia. The research method in this paper is qualitative using a post-positivism approach. Data obtained through observation obtained from journals, documentation and interviews were analyzed descriptively in a relevant and accurate manner. The results of the study show that the implementation of the implementation of open selection at the Pratama High Leadership Position (JPT) has not fully gone well so it is necessary to take steps to be able to make strategic improvements in an effort to implement effective bureaucratic reform so that the practice of KKN (Corruption, Collusion and Nepotism) can be avoided. Thus, it is necessary to improve the practice of civil service reform in Indonesia, especially in the implementation of open selection so that it can provide public services in a selective, objective and better supervisory manner based on applicable policies and regulations.

Published: July 2023

The construction of the “double tutor system” is a crucial link in promoting the comprehensive reform of professional master’s degree postgraduate education, and it is also a comprehensive work that involves the interests of primary stakeholders such as universities, enterprises and industry departments, tutors inside and outside the school, and postgraduate students. During the implementation of the “Double Tutor System”, due to the different interest demands of the main stakeholders and the mutual game between them, the contradictions between academic logic and market logic, internal development law of education and external development environment, personal value and social value are typical. Therefore, the Double Tutor of higher education has become the inevitable trend of education development in colleges and universities in today’s society, which is also a new type of school-enterprise joint training mode. A questionnaire survey was conducted for the master’s group as the research target. It also analyzes the relevant questions of the questionnaire, puts forward relevant feasible suggestions, and solves the relevant problems of the double tutor system for postgraduates in China and Belarus, to promote the training path of professional masters and promote the rapid development of new higher education models.

This article presents the main ethical challenges faced by social work professionals in Spain during the "first wave" of COVID-19 in 2020. The pandemic had a serious impact not only on the health sector, but also in the field of social work. During this time, social workers had to address serious ethical questions regarding issues such as confidentiality breaches, how to fairly distribute available resources, the lack of personal contact and emotional connection with the service users, the difficulties of working in isolation and online, doubts about the reliability of the information they were handling and the difficulty of making proper diagnoses. An international research group led by Dr. Sara Banks conducted a broader research project in collaboration with the International Federation of Social Workers, which collected information through an online questionnaire aimed at social workers from various countries. In this article we analyse the results related to the main ethical challenges faced by social workers in Spain. The research group identified two types of ethical challenges that they have separated into two sections: the first section is related to direct intervention with users, which includes topics such as the lack of emotional support, reliability, use of technology, the appropriate care, compliance with the highest professional standards, confidentiality, vulnerability, and the fair distribu-tion of resources. The other section is related to the ethical challenges around the daily work within social entities, which involved dealing with issues such as the e-social work and coordination difficulties, the management of pressure in social bodies and changes in the intervention methodology.

Published: July 2023

Introduction: Guillain-Barré syndrome (GBS) is an acute inflammatory peripheral neuropathy that occurs after infection or immunization. Wernicke’s encephalopathy (WE) is caused by thiamine deficiency that classically presents with altered mental status, ataxic gait and ophthalmoplegia. Case report: Male, 64 years old, presented with diarrhea, vomiting and hyporexia. Three weeks later, he developed concomitant acute tetraparesis and cognitive impairment. On examination, he presented with persecutory delusions, hallucinations, tetraparesis with global areflexia. The cerebrospinal fluid analysis showed important albuminocytological dissociation. Treatment with intravenous immunoglobulin associated with thiamine was started. The electroneuromyography was compatible with demyelinating sensorimotor polyneuropathy. Brain Magnetic resonance imaging showed FLAIR (Fluid-Attenuated Inversion Recovery) hyperintensities in mamillary bodies and periaqueductal gray matter. The patient was diagnosed with GBS and WE. He was discharged after two weeks with complete resolution of the cognitive impairment and improvement of tetraparesis. Altered mental status in a patient with GBS is not common. There are some reports of patients who presented cognitive disturbances related to autonomic dysfunction and more severe cases, which developed a few days after the onset of the motor condition. The reported patient had a change in mental status concomitantly with a motor condition, reported prolonged gastrointestinal symptoms, in addition to having received intravenous glucose. WE may occur after a short period of thiamine absorption/intake deficiency and may be precipitated by glucose administration. The patient showed rapid cognitive improvement after thiamine supplementation, and had typical EW changes on the brain MRI confirming the diagnosis of WE. Conclusions: We must be aware of changes in mental status as this may indicate thiamine deficiency. The case elucidates the importance of thiamine replacement in patients at risk of vitamin deficiency.

Coenzyme Q10 (CoQ10) biosynthesis defects may lead to primary CoQ10 deficiency. This rare inherited metabolic disorder has been associated with a heterogeneous genetic basis, including rare pathogenic variants in the COQ7 gene. CoQ10 deficiency leads to dysfunction of mitochondrial energy, resulting in several distinct neuromuscular phenotypes, such as myopathy, axonal and demyelinating chronic polyneuropathy and hereditary motor neuronopathy. Herein, we present the first clinical association of COQ7 pathogenic variants with Juvenile Amyotrophic Lateral Sclerosis. A 38-year-old Brazilian man started at age 11 years with a slowly progressive history of distal lower extremity weakness that evolved to the proximal segment, distal extremities of upper limbs and speech disorders. His parents were first degree cousins. His father and brother had similar motor symptoms. Neurological examination disclosed dysarthria, lower limb and distal-dominant quadriparesis, global amyotrophy with dominant distal involvement, and brisk tendon reflexes in the lower limbs. Neuroimaging studies were unremarkable, as well as cerebrospinal fluid analysis. Needle electromyography disclosed diffuse chronic denervation involving cervical, thoracic, and lumbosacral myotomes, and acute denervation (positive sharp waves and fibrillation) in the four limbs; preserved sensory neuroconduction studies. Broad next-generation sequencing-based gene panel testing disclosed the homozygous pathogenic variant c.1A>G in the COQ7 gene. This description expands the pathophysiological basis associated with JALS. COQ7 variants should be included in the differential diagnosis of juvenile-onset motor neuron disease.

Published: July 2023

Introduction: Neurofunctional rehabilitation often employs various approaches to enhance recruitment and muscle strength through overflow, a phenomenon that amplifies the motor response of homologous muscles in the contralateral segment. overflow has been well documented in the literature, particularly in techniques like FNP and cross-education. The phenomenon of overflow is known to facilitate muscle activity in muscles that are not actively stimulated, resulting in unintentional contractions during a resisted isometric activity. Objectives: The objective of this study was to investigate the overflow mechanisms of non-homologous contralateral muscles of the lower limb during an instructed handgrip task. Methods: A total of 90 individuals, with a motor preference for their right upper limb (RUL), were divided into control (CG) and resisted isometry group (RIG) and underwent a protocol involving three maximal hand grip contractions with their RUL and LUL. In assessment 2, the CG performed the same protocol as baseline, while the RIG group performed three maximal isometric contractions of left hip flexion with three maximal contractions of hand flexion with their RUL. statistical analysis was conducted by a multiple comparison analysis of variance with P < 0.05. Results: Observing the data from evaluation 1, both the CG and RIG showed a reduction in strength between the third and first attempt for both the left and right upper limbs (F = 1.07, F = 0.68, respectively). In evaluation 2, the decrease occurred only for the CG in both upper limbs (F = 0.15, F = 1.29, respectively). Conclusion: Our study revealed that maximal muscle strength was maintained in RIG individuals during assessment 2, indicating the existence of overflow when performing an isometric hip flexion task concomitantly with the palmar grip.
