Digital markedsføring før og etter covid-19
Authors: Lervik-Olsen Line , Gustafsson Anders
Published: November 2023

Litt enkelt sagt dreier digital markedsføring seg om alle former for markedsføring som foregår på digitale enheter, på digitale plattformer, i digitale medier, ved bruk av digitale data og ikke minst ved bruk av digital teknologi. Digital markedsføring er langt fra noe nytt: Allerede før covid-19-pandemien oppstod og Norge stengte ned 12. mars 2020, hadde de fleste selskaper og organisasjoner, store som små, en form for markedsføring i digitale kanaler. I første omgang var den drevet fram av intensivert konkurranse, rask teknologisk utvikling og nye forretningsmodeller. Mye tyder likevel på at covid-19-pandemien forandret den digitale markedsføringsarenaen og førte til at aktiviteten her skjøt fart.
Utfordringer med helsekommunikasjon i helseprofesjonspraksis: En pedagogisk-didaktisk analyse av helsekompetanse og den sosiale konteksten
Authors: Larsen Kristian , Pettersen Kjell Sverre
Published: November 2023

Patients have various challenges with health communication and health literacy that constitute personal health risk. Many have language difficulties and limited ability to critically evaluate various health claims. In addition, healthcare personnel also have challenges in explaining themselves, understanding and assessing health knowledge. On the basis of a Norwegian questionnaire survey (2019) on general and digital health competence (N = 373) involving respondents with health education and without, similarities and differences within and between the two groups are described and analysed. Through a critical pedagogical-didactic analysis, health competence is criticised, as health ideals are not universal facts. They are historical and contemporary constructions, and there are cultural differences in body and health ideals as well as unequal access to health knowledge and technologies. Healthcare services and professions must be attentive to these differences and inequalities, and respect the diversity of health ideals and practices. They can better serve vulnerable groups by aspiring to culturally sensitive health communication.

Masterutdannede i barnehagens profesjonsutøvelse – om utdanning, kunnskap og profesjonell praksis
Authors: Kasin Olav
Published: November 2023

I dette kapitlet undersøker jeg hva slags betydning masterutdanning kan ha som kunnskapsbase for praksis i barnehagen. Dette spørsmålet behandles med utgangspunkt i kjennetegn ved profesjonskunnskap, slik det kommer fram i noen utvalgte profesjonsteoretiske og kunnskapsteoretiske arbeider. Disse kjennetegnene knyttes til særpreg ved barnehagelærerprofesjonen, til at barnas behov for omsorg, lek, læring og danning ses i sammenheng, og til at det jobbes for en barnesentrert pedagogikk. I drøftingen av hva slags betydning masterutdanningen kan ha i barnehagens praksis, trekker jeg fram materiale fra intervjuer med tolv masterutdannede barnehagelærere. Her legger jeg vekt på hva de sier om sin egen profesjonsutøvelse i barnehagen, slik som å komme tett på barna og pedagogikken og hvordan faglig trygghet innebærer bruk av fagspråk og litteratur, at de reflekter over hvorfor de gjør det de gjør, og at de har en selvbevissthet i møte med eksterne aktørers ønsker om å påvirke barnehagens mål og arbeidsmåter. Betydningen av utdanningen knytter jeg til hvordan de utøver profesjonalitet i det jeg kaller et kunnskapssosiologisk handlingsrom, det vil si at de har en reflektert tilstedeværelse i selve arbeidet, der ulike former for kunnskap artikuleres, diskuteres, kritiseres og endres.
En kandidatuddannet pædagogs positionering i praksis
Authors: Due Sisse , Rothuizen Jan Jaap
Published: November 2023

Hvordan kan komplekse sammenhænge mellem person, akademisk uddannelse, pædagogisk faglighed og institutionspraksis forstås? I den aktuelle undersøgelse følges fire pædagoger med en akademisk overbygning, som selv havde et ønske om at vende tilbage til den pædagogiske hverdagspraksis gennem halvandet år. De oplever selv, at deres videreuddannelse har bidraget til deres pædagogiske faglighed, men at de i praksis må undersøge, hvordan den kan bringes i spil. Lottes erfaringer er grundlag for en fyldig beretning, der viser de komplekse sammenhænge, der opstår, når livshistoriske erfaringer, akademisk uddannelse, pædagogisk faglighed og institutionspraksis mødes og brydes. Der er således på ingen måde tale om et en-til-en-forhold mellem de forskellige faktorer, snarere om spændingsfelter og dynamikker, heldige sammentræf og forstemtheder. Til sidst tematiseres 1) forholdet mellem akademisk viden og pædagogisk hverdagspraksis, 2) hvilke forventninger man kunne have til en akademisk videreuddannelse, der skal være relevant for den pædagogiske hverdagspraksis og 3) hvordan feltet tager imod og tilbyder positioner til pædagoger med en akademisk videreuddannelse.
Masterutdannede profesjonsutøvere i barnehagens kollegiale fellesskap
Authors: Ivarson Kristina Axelsen
Published: November 2023

Med utgangspunkt i intervjuer med barnehagelærere med masterutdanning forsøker forfatteren i dette kapitlet å belyse hvem barnehagelærere med masterutdanning er som profesjonsutøvere, og hvilken rolle de har eller tar i det kollegiale fellesskapet. Det er de transkriberte intervjuene som danner grunnlaget for analysene og diskusjonen som føres i kapitlet. Det som kommer frem i intervjuene, er at masterutdanning har bidratt med større trygghet og har gitt barnehagelærerne større mot til å ytre seg kritisk til og stille spørsmål ved den pedagogiske praksisen i barnehagen. Det kommer også frem at det kan oppleves utfordrende å være en kritisk profesjonsutøver sammen med andre. Barnehagelærerne forteller om hvordan de etter masterutdanningen møter utfordringer på en annen måte, og at de justerer rollen sin for å kunne være den profesjonsutøveren de selv ønsker å være, og som de identifiserer seg med.

Published: November 2023

Abstract — To maintain battery performance, it is necessary to have a battery monitoring system that functions to determine several parameters in the battery, such as voltage, current, capacitance and battery capacity. The technology for knowing battery capacity is often known as state of charge (SOC). State of charge (SOC) is the ratio of the remaining energy to the maximum energy capacity of the battery. State of charge values ​​are often expressed in percentage form, 0 percent -100 percent. Estimating the value of the state of charge is quite important in battery monitoring technology. The lead acid battery testing process is carried out for 10 hours or 36000 seconds, both in the condition of discharging and charging the battery. In this study, the initial State of Charge (SOC) value for the battery is given, namely the upper limit and lower limit. The upper limit value for the initial State of Charge (SOC) is 100 percent, while the lower limit value is 20 percent. In the process of discharging the lead acid battery, it can be seen that the current value when discharging is stable at 1.2 Amperes. The charging current value is very constant, namely at 0.425 A. Meanwhile, the charging voltage value is also constant at 12.215 V.

Published: November 2023

Abstract — This paper proposes self tuning Proportional-Integral/Proportional gain controller parameter in a Two Degree of Freedom (2DoF) using fuzzy logic method for speed control of permanent magnet synchronous motor. The self tuning method can automatically determine the PI-P parameters using a fuzzy logic control system. Speed control of the 3-phase permanent magnet synchronous motor is carried out by changing the 3-phase system (a-b-c) to a 2-phase system (direct-quadrature) using the vector control method. SVPWM method is used to modulate six switches on a 3 phase inverter. The results obtained using MATLAB Simulink show that by using a self-tuning fuzzy logic control system, high motor performance results are obtained, where the speed response of the permanent magnet synchronous motor shows that the step response and disturbance response are close to the ideal response.

Published: November 2023

This study aims to simulate power quality analysis using fuzzy logic to increase the efficiency of the power system. Poor power quality can cause disturbances in the electric power system and reduce the efficiency of the energy used. Therefore, improving power quality is one of the main focuses in the electric power industry.The fuzzy logic method is used in this study to evaluate power quality based on relevant parameters, such as voltage, current, frequency and harmonics. Fuzzy logic is able to overcome the uncertainty and complexity of data related to electric power systems, and provide more adaptive and intelligent solutions. In this study, simulations were carried out using special software that implements fuzzy logic to analyze power quality. The input data obtained from the electric power system is used to build a fuzzy logic model. Then, the simulation results are used to identify existing power quality problems and propose appropriate improvement strategies.The simulation results show that the use of fuzzy logic can significantly increase the efficiency of the power system by minimizing disturbances and optimizing power quality. In addition, fuzzy logic also provides the ability to predict the future conditions of the electric power system and take the necessary precautions. This research has important practical implications in the field of power systems. By using fuzzy logic in power quality analysis, power companies and grid operators can optimize power system operations, reduce power losses, improve energy efficiency, and ensure reliable electricity supply to consumers.

We live in a world that is changing at an unprecedented rate in all areas of life. Technology, automation and artificial intelligence will be the deciding factors of major changes in the global socio-economic picture by 2030. Because the road to a sustainable economy is unquestionably challenging, the onset of the Covid 19 has slowed this progress, and in some countries, especially low-income countries, it has even declined. In this context, the reality of recent months has shown humanity that we are still very vulnerable to the danger posed by military wars, with weapons and tanks, as we no longer thought possible in the context of the current explosion of information and technology, AI and VR. Unfortunately, we cannot oppose the evolution of humanity, with or without wars, including economic ones, with the major risk that things will “go crazy”, especially if the technology becomes a tool against humanity.

Published: November 2023

Plagiarisme atau tindakan plagiat merupakan sebuah aksi yang dilakukan secara sengaja maupun tidak sengaja untuk mendapatkan sebuah keuntungan seperti nilai dalam tugas dengan mengambil sebagian serta seluruhnya karya tulis orang lain tanpa mencantumkan nama pengarang atau sumber karya. Praktik plagiarisme sering terjadi di universitas dan biasanya dilakukan oleh mahasiswa. Plagiarisme dapat dibedakan berdasarkan cara penerapannya, yaitu Word Switch Plagiarism, Style Plagiarism, Metaphor Plagiarism, Idea Plagiarism, dan Self Plagiarism. Para mahasiswa mengetahui secara sadar apa itu plagiarisme dan banyak juga yang melakukan plagiarisme padahal mengetahui bahwa plagiarisme termasuk tindakan kejahatan. Alasan para mahasiswa melakukan plagiarisme ialah karena kurangnya pemahaman materi atau tugas yang diberikan, malas mencari informasi, terlalu cepat waktu pengumpulan tugas, dan keinginan mendapatkan nilai yang terbaik. Para mahasiswa menyarankan solusi untuk menanggulangi tindakan plagiarisme seperti diadakannya sosialisasi terkait peraturan plagiarisme, dimulai pemberlakuan penggunaan Turnitin, dan para tenaga pendidik dapat membuat prasyaratan untuk tugas. Plagiarisme dapat mempengaruhi nama baik universitas. Peraturan plagiarisme yang dibentuk oleh pemerintah berada di pada Peraturan Menteri Pendidikan Nasional Republik Indonesia Nomor 17 Tahun 2010. Pihak universitas sangat berpengaruh besar dalam mengurangi tindakan plagiarisme dilingkungan universitas. Universitas harus memiliki buku panduan dan peraturan plagiarisme serta memberikan sanksi terhadap pelaku plagiarisme. Universitas juga harus menanamkan kejujuran serta berpikir kreatif dalam diri para mahasiswa.

Listening to the depths of coral reefs in French Polynesia: deciphering the whoot
Authors: Raick Xavier
Published: November 2023

Les paysages acoustiques englobent des sons d’origine biologique, anthropique et géophysiques. Le monitoring par acoustique passive des écosystèmes marins utilise ces sons pour obtenir des informations sur ces environnements. Les récifs coralliens tropicaux profonds, également connus sous le nom de mésophotiques, sont des habitats peu explorés qui abritent une grande diversité d'espèces de poissons. Les poissons récifaux émettent une variété de sons, dont certains restent encore peu compris. Dans le cadre de cette étude, des enregistrements acoustiques ont été réalisés dans les récifs coralliens mésophotiques de Polynésie française. L'objectif était de caractériser le cycle jour/nuit d’un son particulier préalablement découvert, appelé whoot. L'expédition « Under The Pole III » a offert l’opportunité de collecter des données à l'aide d’enregistreurs acoustiques couplés à des hydrophones, positionnés à différentes profondeurs (−60 m et −120 m) à Bora-Bora, Mangareva, Moorea, Rangiroa, Raroia et Tikehau. Les enregistrements ont ensuite été analysés afin de détecter et de caractériser le cycle jour/nuit du son whoot. Des différences entre les deux profondeurs étudiées et entre les différentes îles étudiées ont été mises en évidence. En général, ce son était principalement présent en début et en fin de nuit, mettant ainsi en évidence son caractère nocturne acoustique chez l’espèce produisant les whoots. Ce résultat devrait contribuer à l’identification de l’espèce de poisson responsable de ce son caractéristique de la scène musicale sous-marine profonde polynésienne, et aider à une meilleure compréhension des populations de poissons des récifs coralliens mésophotiques par l’acoustique passive.

Modified messenger RNA (mRNA) represents a rapidly emerging class of therapeutic drug product. Development of robust stability indicating methods for control of product quality are therefore critical to support successful pharmaceutical development. This paper presents an ion-pair reversed-phase liquid chromatography (IP- RPLC) method to characterise modified mRNA exposed to a wide set of stress-inducing conditions, relevant for pharmaceutical development of an mRNA drug product. The optimised method could be used for separation and analysis of large RNA, sized up to 1000 nucleotides. Column temperature, mobile phase flow rate and ion-pair selection were each studied and optimised. Baseline separations of the model RNA ladder sample were achieved using all examined ion-pairing agents. We established that the optimised method, using 100 mM Triethylamine, enabled the highest resolution separation for the largest fragments in the RNA ladder (750/1000 nucleotides), in addition to the highest overall resolution for the selected modified mRNA compound (eGFP mRNA, 996 nucleotides). The stability indicating power of the method was demonstrated by analysing the modified eGFP mRNA, upon direct exposure to heat, hydrolytic conditions and treatment with ribonucleases. Our results showed that the formed degradation products, which appeared as shorter RNA fragments in front of the main peak, could be well monitored, using the optimised method, and the relative stability of the mRNA under the various stressed conditions could be assessed

Boron nitride (BN) is a promising two-dimensional material as well as a potential wide-bandgap semiconductor. Chemical vapor deposition (CVD) is commonly used to deposit single layers or thin films of BN, but the deposition process is insufficiently understood at an atomic scale. We study the CVD of BN using two boron precursors, the organoboranes, triethylborane and trimethylborane. Using high resolution (scanning) transmission electron microscopy and electron energy loss spectroscopy we show that hexagonal-BN (h-BN) nucleates and grows epitaxially for ~4 nm before it either polytype transforms to rhombohedral-BN (r-BN), turns to less ordered turbostratic-BN or is terminated by a layer of amorphous carbon. We propose that the carbon in the organoboranes deposits on the epitaxially growing h-BN surface and this either leads to the polytype transition to r-BN, the transition to less ordered BN growth or complete surface poisoning with carbon terminating BN growth. Our results question the use of organoboranes in CVD of epitaxial BN films, and the polytype stability of h-BN growing on graphene.
Application of enzyme-like MnO2 nanoparticles as cathode materials for Li-ion batteries
Authors: Hormozi Jangi Saeed Reza
Published: November 2023

In this study, the enzyme-like manganese dioxide nanoparticles with high peroxidase-like activity were synthesized and then characterized. The experimental studies proved the high Li-electroactivity of the as-prepared nanoparticles which makes these nanozymes for applying as cathode materials for Li-ion batteries. To determine the redox peaks of Mn4+/Mn3+ against Li anode, the cyclic voltammetry was used, revealed that the enzyme-like manganese dioxide nanoparticles as cathode materials can receive the Li(I) ions and then give it back to the anode. The charge-discharge tests were performed for several successive operational cycles. The results showed that the capacity of enzyme-like manganese dioxide nanoparticles is as high as 164.9 mAhg−1 at 30 mAg−1 while at 1000 mAg−1 the capacity was found to be about 46 mAhg−1.
Simulation of Aqueous Solutes Using the Adaptive Solvent-Scaling (AdSoS) Scheme

The Adaptive Solvent-Scaling (AdSoS) scheme [J. Chem. Phys. 155 (2021) 094107] is an adaptive-resolution approach for performing simulations of a solute embedded in a fine- grained (FG) solvent region surrounded by a coarse-grained (CG) solvent region, with a continuous FG↔CG switching of the solvent resolution across a buffer layer. Instead of relying on a distinct CG solvent model, AdSoS is based on CG models defined by a dimensional scaling of the FG solvent by a factor s, accompanied by the s-dependent modulation of its mass and interaction parameters. The latter changes are designed to achieve an isomorphism between the dynamics of the FG and CG models, and to preserve the dispersive and dielectric solvation properties of the solvent with respect to a solute at FG resolution. As a result, the AdSoS scheme minimizes the thermodynamic mismatch between the different regions of the adaptive-resolution system. The present article generalizes the scheme initially introduced for a pure atomic liquid in slab geometry to more practically relevant situations involving: (i) a molecular dipolar solvent (e.g. water); (ii) a radial geometry (i.e. spherical rather than planar layers); and (iii) the inclusion of a solute (e.g. water molecule, dipeptide, ion or ion pair).

We report on anomalous transport of ions in solution through macroscopic arrays of vertically aligned, surface-charged boron-nitride nanotubes (BNNTs). The 3- and 12nm-diameter BNNTs revealed two atypical transport phenomena: (i) ultra-fast cation-selective diffusion under concentration gradients that exceeded Fickian diffusion by up to 31-fold and (ii) anomalous relative diffusion rates and ionic conductances for alkali-metal ions (K+, Na+, and Li+) that were opposite to the ordering of their bulk mobilities in solution, and also different from that observed in carbon nanotubes and 2D boron-nitride (BN) nanochannels. The enhanced diffusive transport is shown to result from diffusio-osmosis at the charged BN walls, with the enhancement scaling inversely with pore diameter. The anomalous relative diffusivities for different cations is seen to arise from ion-specific interactions with the charged surface of the BNNTs. These unusual transport phenomena, as well as the flexible and scalable membrane-fabrication process, may enable ion-selective membranes optimized for “blue” energy conversion, lithium recovery, and other molecular separations. As an example, macroscopic arrays of aligned BNNTs in a salt-concentration gradient produced per-pore osmotic-power densities up 15,300 W/m2, with energy-conversion efficiencies approaching the theoretical maximum of 50%.

Uso de crack, experiência espacial e sentimentos: a lugaridade fugaz entre euforia e ressentimento no Centro Histórico de Belém
Authors: Pereira Dias Alan
Published: November 2023

O artigo versa sobre cenas abertas de uso de crack e/ou similares, aglomerações e apropriações de fragmentos do espaço público que gravitam em torno dessas substâncias psicoativas. Ancorado em um referencial geográfico e fenomenológico-existencial, objetivou-se analisar o papel dos sentimentos na constituição de imagens e sentidos de lugar por pessoas que habitam cenas de uso no Centro Histórico de Belém, de maneira a esboçar uma geografia emocional. A partir de trabalhos de campo e entrevistas, identificou-se um contexto de vulnerabilidade e desfiliação social, onde os sujeitos estão em situação de rua ou evitam voltar para o lar. Assim, suas lugaridades são marcadas por um embaralhamento de imagens topofílicas (afetivas) e topofóbicas (negativas) em relação à cena, atravessadas pela euforia fugaz da droga, o ressentimento em torno do uso e as implicações negativas do contexto.
O sangue estampado - menstruação, antropologia das emoções e design em um projeto inspirado no livro de Lara Owen
Authors: Pelúcio Larissa Maués , Aires Ramos Helena Trevizan
Published: November 2023

Este artigo apresenta e discute um conjunto de estampas que foram concebidas a partir dos arquétipos menstruais propostos por Lara Owen, em seu livro Seu Sangue é Ouro. Os desenhos foram pensados como linguagem de resistência e ressignificação das emoções em torno do ciclo menstrual associado, pelas pessoas que participaram da pesquisa, à vergonha, ao medo e, por vezes, ao desejo de ter nascido com outro corpo. O ciclo menstrual é discutido a partir de aportes críticos dos estudos feministas pós-estruturalistas, da antropologia das emoções contextualista e do design emocional. Tencionamos as abordagens biologizantes em torno da menstruação e das emoções propondo-nos, por meio dos desenhos estampados em camisetas, provocar outros olhares e politizar as emoções em torno da menstruação.

Emoções e Moralidades constituíram-se como rubricas acadêmicas e metaconceitos que apontam para esforços contemporâneos (de 1970 para cá) de repensar teórico-metodologicamente o exercício socioantropológico. Entretanto, muitas das discussões que fazem parte da agenda de alguns dos clássicos da sociologia e da antropologia, que direta ou indiretamente tocaram nesse temas, podem ser compreendidas como debates em torno das Emoções e Moralidades para o entendimento do Indivíduo, do Social e da Cultura.
