    The communication industry in Colombia has promoted over the last decade a process of transformation and design of new proposals in both traditional media and digital natives, a range of operational strategies to distribute textual, sound, and visual formats through the social networks, adapting the content to the particularities and attributes of each one of them. The irruption of the implementation of the peace accords, the pandemic and citizen nonconformity taken to the streets have served to verify the real dimension of this reconfiguration, as well as its effectiveness in terms of credibility and scope in the face of an unprecedented scenario that has transformed the social and cultural interaction of citizens through technology. This research focuses on the response of Colombian journalistic agents to the demand for information during the period 2019, 2020 and 2021, from a mixed quantitative-descriptive methodology that allows identifying, quantifying, and assessing the relationship between newspapers, radio stations and television channels with the new platforms. The corpus of the study is made up of the publications on social networks of the Colombian media with the greatest circulation according to the Colombian Association for Media Research: two newspapers (El tiempo and El espectador), five radio stations (Caracol radio, W radio, Blu radio, RCN radio and La FM) and the news from the two television networks with the highest audience (Noticias Caracol and Noticias RCN). The results of the study show a reinforcement of the brand of the journalistic company as a reference for information and credibility, however, the current situation has not served to legitimize the role of journalists in social networks and has underlined the fragility of a media ecosystem highly exposed to polarization, manipulation, and mistrust. Resumen La industria de la comunicación en Colombia ha impulsado a lo largo de la última década un proceso de transformación y diseño de nuevas propuestas tanto en medios tradicionales como en nativos digitales, gama de estrategias operativas para distribuir formatos textuales, sonoros y visuales a través de las redes sociales, adaptando los contenidos a las particularidades y atributos de cada una de ellas. La irrupción de la implementación de los acuerdos de paz, la pandemia y el inconformismo ciudadano llevado a las calles han servido para constatar la dimensión real de esa reconfiguración, así como su efectividad en términos de credibilidad y alcance ante un escenario inédito que ha transformado la interacción social y cultural de los ciudadanos a través de la tecnología. Esta investigación centra su atención en la respuesta de los agentes periodísticos colombianos a la demanda de información durante el periodo 2019, 2020 y 2021, desde una metodología mixta cuantitativo-descriptiva que permite identificar, cuantificar y valorar la relación entre periódicos, emisoras de radio y canales de televisión con las nuevas plataformas. El corpus del estudio está compuesto por las publicaciones en redes sociales de los medios colombianos con mayor difusión según la Asociación Colombiana de Investigación de Medios: dos periódicos (El tiempo y El espectador), cinco cadenas de radio (Caracol radio, W radio, Blu radio, RCN radio y La FM) y los informativos de las dos cadenas televisivas de mayor audiencia (Noticias Caracol y Noticias RCN). Los resultados del estudio evidencian un refuerzo de la marca de la empresa periodística como referente de información y credibilidad, no obstante, la coyuntura del momento no ha servido para legitimar el papel de los periodistas en las redes sociales, y ha subrayado la fragilidad de un ecosistema mediático muy expuesto a la polarización, la manipulación y la desconfianza.

    The current COVID-19 global pandemic has amplified the pressure on the agriculture sector, inciting the need for sustainable agriculture more than ever. Thus, in this review, a sustainable perspective of the use of remotely piloted aircraft (RPA) or drone technology in the agriculture sector is discussed. Similarly, the types of cameras (multispectral, thermal, and visible), sensors, software, and platforms frequently deployed for ensuring precision agriculture for crop monitoring, disease detection, or even yield estimation are briefly discoursed. In this regard, vegetation indices (VIs) embrace an imperative prominence as they provide vital information for crop monitoring and decision-making, thus a summary of most commonly used VIs is also furnished and serves as a guide while planning to collect specific crop data. Furthermore, the establishment of significant applications of RPAs in livestock, forestry, crop monitoring, disease surveillance, irrigation, soil analysis, fertilization, crop harvest, weed management, mechanical pollination, crop insurance and tree plantation are cited in the light of currently available literature in this domain. RPA technology efficiency, cost and limitations are also considered based on the previous studies that may help to devise policies, technology adoption, investment, and research activities in this sphere.

    Digital Transformation has generated much research and curiosity recently, with the COVID-19 global pandemic accelerating its pace across all industry sectors. Current literature has not adequately provided a comprehensive understanding of Digital Transformation Leadership (DTL). The objective of this research is to explore the characteristics of DTL by undertaking a comprehensive review of Information Systems literature using a systematic procedure of identifying and coding 87 research papers, resulting in 600 coded excerpts, capturing the ‘who’ and ‘what’ of DTL. Our analysis identifies eight DTL characteristics, namely: digital strategist, digital culturalist, digital architect, customer centrist, organisational agilist, data advocate, business process optimiser and digital workplace landscaper. We discuss mapping the DTL characteristics to c-suite roles, presenting a taxonomy from the literature, of interest to both academics and practitioners. This research raises the awareness of the concept of DTL characteristics, especially amongst those in positions of leadership and decision making authority. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

    During the southern summer of 2020, large phytoplankton blooms were detected using satellite technology in Chile (western Patagonia), where intensive salmonid aquaculture is carried out. Some harvesting sites recorded massive fish mortalities, which were associated with the presence of the dinoflagellate species Cochlodinium sp. The bloom included other phytoplankton species, as Lepidodinium chlorophorum, which persistently changed the colour of the ocean to green. These blooms coincided with the government-managed emergency lockdown due to the COVID-19 pandemic. Local in situ sampling was slowed down. However, imagery from the Copernicus programme allowed operational monitoring. This study shows the benefits of both Sentinel-3 and Sentinel-2 satellites in terms of their spectral, spatial and temporal capabilities for improved algal bloom monitoring. These novel tools, which can foster optimal decision-making, are available for delivering early alerts in situations of natural catastrophes and blockages, such as those occurred during the global COVID-19 lockdown. Highlights • Copernicus programme provides crucial data during the COVID-19 lockdown in Chile. • Sentinel-2/3 satellites allow monitoring an algal bloom harmful for the aquaculture. • A dinoflagellates bloom produces massive salmonid mortalities in the harvesting sites. • Mesoscale and high-resolution satellite data detect precise location of the HAB. • Early alarm during pandemic or catastrophic events can advance optimal decision-making.

    This thesis addresses the reflection of how Portuguese healthcare sector route to a digital transformation during the first wave of Covid-19 pandemics (from march to July of 2020), which caught the world by surprise. Governments were obliged to apply contingencies measures that forced social distance. And technology was the key to support the effective adaptation of companies across all sectors. Focusing on the changes occurring in the Portuguese healthcare sector and the expectation for the future of this sector, it will be observed the main different solutions implemented considering the observation stages (Prevention & Diagnosis; Treatment and Aftercare & Monitorization).

    För ungefär två år sedan fick hela världen och därmed vi i Sverige förändra våra livsstilar markant från vad vi var vana vid. Coronapandemin och sjukdomen covid-19 spred sig snabbt och allt för många omkom till följd av smittan. För att bromsa och försöka stoppa smittan ställde vi om, där det var möjligt, till distansarbete. Skolor fick på rekordkort tid ställa om till distans och lärare fick hålla undervisningen genom digitala program som Zoom och Microsoft teams. Övergången från undervisning samt arbete på distans påverkade, och påverkar fortfarande, både barn och vuxna runtom i världen. Att studera hemifrån för barn innebär en markant ökning av eget ansvar vilket kan vara påfrestande. Att studera hemifrån innebär vidare att den miljön många barn är vana att arbeta i förändrats. Alla barn blir på ett eller annat sätt påverkade av att arbetsmiljön rör sig från skolan till hemmet. Det kan vara både i positiv och negativ riktning. Det som dock händer är att barn som lever i osäkra och olämpliga hemmamiljöer blir påverkade i större utsträckning av digitaliseringen än andra barn med trygga hemmiljöer. Det är därför viktigt att ta hänsyn i dessa tider till principen om barnets bästa. Med hänsyn till den snabba digitaliseringen som skett är det viktigt att hänsyn tas till SoL, LVU och principen om barnets bästa. Till följd av digitaliseringen förlorar barn skolan som sin fristad och hälsan hos utsatta barn riskerar därmed att påverkas i negativ riktning. Till följd av en ökande psykisk och fysisk ohälsa är det viktigt att bland annat socialtjänsten vet i vilken utsträckning de kan använda sig utav digitala medel för att intervjua barn. Detta då både SoL, LVU och barnkonventionen är omfattande regleringar. Det är, som en lärare på universitet påpekade under en föreläsning, att vi måste se utöver lagen. Med detta menade han att det är riktiga personer bakom besluten och inte enbart något teoretiskt i text. I praktiken har det visat sig att det föreligger osäkerheter när barn blir intervjuade eller samtalar med vuxna på distans. I ett fall använde sig mamman av en radiointervju för att samtala med ett barn. I ett annat fall försökte mamman vid samtal över telefon övertala sitt barn att det inte trivdes i familjehemmet och att det ville komma hem till mamman. Det finns därmed osäkerheter när socialtjänsten inte fysiskt på plats kan samtala med barnet. Det är därför viktigt att veta när och om det överhuvudtaget är lämpligt att intervjua barn på distans. Det finns idag inget som hindrar socialarbetare från att intervjua och samtala med barn på distans. Det är därmed viktigt att reda ut hur dessa former av samtal med barn borde ske. Vid e-mailkonversationer med kommuner framkom det att de varken hade riktlinjer eller handböcker. När jag mejlade Socialstyrelsen fick jag till en början inget svar. Efter att ha vidarebefordrat samma mejl till dem fick jag som svar att jag skulle vända mig till landets kommuner för riktlinjer. För att sammanfatta det hela behöver en utarbetning av riktlinjer och handböcker ske så att myndigheter och kommuner har samma utgångspunkt i frågan. Barn ska inte få olika möjligheter på grund av digitaliseringen och att olika aktörer arbetar på olika sätt. About two years ago the whole world and therefore Sweden had to change it’s lifestyles remarkably from what we were used to. The corona pandemic and the disease covid-19 was spreading at a rapid pace and too many people died because of the virus. Countries had to change to remote work where it was possible. This also applied to schools which had to, at a record speed, change to distance learning through digital programs like Zoom and Microsoft teams. The transition to remote work and distance learning affected, and still does, both children and adults around the world. For a child to study from home means a significant increase of self responsibility which for some can be stressful. To study from home also means that their usual work enviroment for studying changes. Every child is affected in one way or another when the work enviroment changes from school to home. This can be in both a negative and positive direction. The digitlisation and corona pandemic affected children with worse home enviroments to a greater extent than those with safe ones. Therefore it is important that we take the principle of the best interests of the child into consideration. In light of the rapid digitalisation that has happened it is important to take the Social Services Act (SoL), the Care of Young Person (Special Provisions) act (LVU) and the principle of the best interests of the child into consideration. Children lose the school as their sanctuary due to the digitalisation and corona pandemic which risks to impact on them negatively. Due to an increased psychological and physical ill health, it is important that the social services know to which extend they can use digital means to interview children. A teacher at the university once told me that we have to look beyond the law. He meant that there are actual people behind the decisions we make and not just something theoretical. It has shown in practice that there are uncertainties revolving around remote interviews between children and adults. There is one case where the mother used radiointerviews to interview her child. In another case the mother tried, over the phone, to convince her child that it wanted to come back home to her instead of staying in its current family home. Therefore, uncertainties exist when the social services can’t interview children in person. It is for these reasons important to know when and if it is appropriate to conduct remote interviews with children. There is nothing today that restrains social workers from conducting remote interviews with children. For this reason it is important that we sort out how these forms of interviews should take place. When I emailed different municipalties it turned out that they did not have guidelines or handbooks on how to conduct remote interviews with children. When I emailed the National Board of Health and Welfare they told me to reach out to the municipalties in Sweden for guidelines. To summarise, we need to formulate guidelines and handbooks for the authorities and municipalties so they have the same starting point. Children should not get different opportunites because of the digitalisation or that the authorities have different work procedures.

    Abstract This paper argues that there is an emergent digital culture in the art and cultural sector in Hanoi, which is producing a paradigm shift in the nature of work for cultural professionals, the way of preserving and displaying art collections, as well as the nature of international connections. The advent of the “fourth industrial revolution” in Vietnam has brought about advances in digitization. While this transition is crucial in achieving national sustainable development goals, Vietnam remains at a disadvantage on a global scale due to country-specific challenges in digitization that include lack of human, technical, and financial resources. These challenges are hindering the pace and quality of the digitization process and impeding the ability of cultural professionals to utilize digital platforms. In addition, the global digital divide is having impacts on access, inclusion, and representation. This shows that the challenges faced in the digitization process are not only about access to technology but also about much more deep-seated issues related to culture, history, and social inequalities. This is especially pertinent during the Covid-19 pandemic, which has highlighted inequalities in access and inclusion. The research draws on 20 semi-structured interviews with cultural professionals across Hanoi. The interviews were carried out during the Covid-19 pandemic and addressed its impact on digitization projects and the use of digital technologies for work. The findings show how geopolitical and socioeconomic factors can suppress the ability to adopt new digital technologies, which is hindering the ability to exploit the opportunities of digitization. Yet, the Covid-19 pandemic has allowed more time to focus on digitization projects and to utilize digital tools and platforms, especially with free open-source software or platforms such as Facebook. This has become one route toward exploiting the opportunities of digitization for increased exposure, creation of digital resources, and rebalancing the discourse and amount of content circulating online regarding Vietnamese art and culture.

    The COVID-19 brings back the debate about the impact of disease outbreaks in economies and financial markets. The error correction terms (ECT) and cointegration processing tools have been applied in studies for identifying possible transmission mechanisms between distinct time series. This paper adopts the vector error correction model (VECM) to investigate the dynamic coupling between the pandemics (e.g., the COVID-19, EBOLA, MERS and SARS) and the evolution of key stocks exchange indices (e.g., Dow-Jones, S&P 500, EuroStoxx, DAX, CAC, Nikkei, HSI, Kospi, S&P ASX, Nifty and Ibov). The results show that the shocks caused by the diseases significantly affected the markets. Nonetheless, except for the COVID-19, the stock exchange indices reveal a sustained and fast recovering when an identical length time window of 79 days is analyzed. In addition, our findings contribute to point a higher volatility for all financial indices during the COVID-19, a strong impact over the Ibov-Brazil and its poor recover when compared to the other indices.

    The daily life of people is changing due to the increase in climate change effects. In the times of historic Covid-19 pandemic event, by the precautions like stay at home, people tried to obey those cautions. This kind of protections decreased the CO2 gas emissions by 17%, obtaining the world returned to 2006 gas emissions values. The air became more breathable and the nature began to repair itself without the touch of people. As the population grows, feeding this population became a separate problem. People started to destroy forest areas because more agriculture was needed for more nutrition. Of course, this destruction also had a direct impact on climate change. Humanity once again saw that it had to develop with nature, not against nature. This eye-opening process will force people to act quickly on what needs to be done for climate change. Even though the relatively less emission comes from the agriculture, this sector has to transform itself by new technologies due to its strategical position. Vertical farming alternative is a candidate for this conversion process. Many methods in vertical farming are handled in this chapter. Some cultivation methods as hydroponic, aeroponic and aquaponic systems are dealt also. Energy and water consumption, yield, and scalability criteria are examined for the vertical farming under climate effects. In addition, some newly technologies like artificial intelligence applied to vertical farming are presented in this study. To see the benefit of this agricultural method a feasibility and economic analysis had to be made, so it’s done with real data. Interesting results and inferences have been obtained and presented at the end of the study.
