In order to develop weather-based yield prediction models for rice and grass pea in coastal saline zone of West Bengal, the experiments were conducted with rice (cv. CR 1017) and grass pea (cv. Bio L 212) in the rainy and winter seasons, respectively of 2016-17 and 2017-18. Rice was sown in nursery bed on six different dates starting from June 15 to July 19 at weekly interval in both rainy seasons in two different land situations viz. medium upland and medium lowland. Likewise, grass pea was sown on six different dates just before harvesting of rice. It was observed that both early sown rice and grass pea resulted in higher grain yield and took more time to mature under medium lowland situation irrespective of sowing dates. Correlation study revealed that air temperature during sowing to transplanting phase exhibited significant positive correlation with grain of rice in medium upland (Tmax = 0.76**, Tmin = 0.69*) and medium lowland (Tmax = 0.93**, Tmin = 0.81**) situations. On the other hand, maximum temperature and total solar radiation during 100% emergence to 100% flowering stage were negatively associated with the grain yield of grass pea in both medium upland (Tmax = -0.69*, Accumulated solar radiation = -0.73**) and medium lowland (Tmax = -0.74**, Acc. solar radiation = -0.77**) situations. Grain yield of rice and grass pea could be predicted with 94.4% and 87.4% predictability. Pre-harvest forecasting of grain yield was possible with 77.3% for rice and 83.8% for grass pea.

Studies on wheat-weather relationship were carried out at Pusa (25.98 oN, 85.67 oE, 52 m), Bihar situated in middle Gangetic plains of India, with three popular wheat cultivars viz. RW 3711, HD 2824 and HD273, grown under five fixed dates of sowing viz. 15 November, 25 November, 5 December, 15 December and 25 December, for five consecutive rabi seasons from 2011-12 to 2015-16. Thresholds of maximum temperature (Tmax), minimum temperature (Tmin) and bright sunshine hours (BSH), associated with higher productivity, occurring at different phenophases, were determined. Results revealed that temperature played a crucial role in achieving higher grain yield of wheat. Both Tmax and Tmin during flowering to milking and flowering to maturity phases increased with delayed sowing dates beyond 25 November with consequent reductions in grain yield. During 50 % flowering to milk stage, Tmax and Tmin above 24.6 oC and 11.6 oC, respectively, reduced grain yield below 4000 kg ha-1; significant reduction in grain yield was also noted beyond maximum temperature of 26.9 oC. During flowering to milk and flowering to maturity phases, Tmax and Tmin exhibited highly significant negative correlation with grain yield, indicating higher temperatures causing lower grain yield. With delayed sowing, sensitive phases of the crop experienced higher air temperatures which led to reduction in grain yield. An increase of Tmax from 29.2 to 32.1 oC during flowering to maturity phases reduced the wheat productivity drastically in this region of Indo-Gangetic plains. Grain yield declined by 399 kg ha-1 per 1 oC rise in Tmax during 50 % flowering to maturity stage. Considering grain yield vis-à-vis temperature regimes during flowering to maturity stage, the most important recommendation for the farmers of the region would be to finish wheat sowing before 25 November in order to enable them to escape terminal heat stress in wheat and thereby realizing higher grain yield. The anthesis-time management by manipulating sowing dates could be a realistic adaptation strategy for attaining optimum grain yield under changing climate scenario.

The impact of climate change on agriculture is well studied yet there is scope for improvement as crop specific and location specific impacts need to be assessed realistically to frame adaptation and mitigation strategies to lessen the adverse effects of climate change. Many researchers have tried to estimate potential impact of climate change on wheat yields using indirect crop simulation modeling techniques. Here, this study estimated the potential impact of climate change on wheat yields using a crop specific panel data set from 1981 to 2010,for six major wheat producing states. The study revealed that 1°C increase in average maximum temperature during the growing season reduces wheat yield by 3 percent. Major share of wheat growth and yield (79%) is attributed to increase in usage of physical inputs specifically fertilizers, machine labour and human labour. The estimated impact was lesser than previously reported studies due to the inclusion of wide range of short-term adaptation strategies to climate change. The results reiterate the necessity of including confluent factors like physical inputs while investigating the impact of climate factors on crop yields.

Neste trabalho é proposta a aplicação dos conceitos de energia e densidade de movimento em sistemas inteligentes de tráfego urbano, usados como ferramenta para modelagem e atuação em uma rede de tráfego urbano. A principal contribuição está relacionada com a metodologia de modelagem que, ao adotar a quantidade de movimento como variável de estado de modelo, reduz sua estrutura e consequentemente facilita a utilização para um controle de tráfego por região. Foram coletados dados reais da BHTrans de cinco regiões do centro da cidade de Belo Horizonte, e obtidas métricas que associam a velocidade média e o tamanho das filas de veículos para o cálculo da densidade de movimento. Testes foram feitos utilizando um simulador de tráfego e os resultados foram comparados com dados reais das vias.
BAG SKÆRMEN PÅ EN DIGITAL PLATFORM

Published: December 2021

I denne artikel undersøges det manuelle og algoritmiske arbejde, der foregår bag skærmen på en digital platform, som er designet til at afhjælpe og forebygge ensomhed. Platformen udbydes til kommuner af en privat virksomhed og finansieres af kommunerne via et abonnement, som giver kommunens borgere fuld adgang til at oprette sig som brugere og benytte platformen gratis. Baseret på en etnografisk undersøgelse af virksomheden, kommuner og brugere ser vi nærmere på det omfattende og usynlige arbejde, der foregår bag skærmen på Venskabsportalens brugergrænseflade og viser, hvordan dette arbejde artikuleres og mobiliseres manuelt såvel som digitalt via algoritmer. Konkret viser dette arbejde sig gennem et omfattende manuelt og digitalt screeningsarbejde samt online og offline promoveringen af platformen. Vi viser, hvordan det er en krævende og omfattende proces, som er rettet mod, at brugere er aktive på platformen, at de får svar, at de har tillid til den, samt at kommunerne forbliver tilfredse med samarbejdet. Hermed udfordres forståelsen af platformen som neutral, automatisk og teknisk, og den fremstår i stedet som en skrøbelig anordning af forbindelser mellem mennesker og teknologi, som kontinuerligt skal vedligeholdes for ikke at bryde sammen. Vi viser, hvordan der opstår et paradoksalt forhold til teknologien, når Venskabsportalen på den ene side mobiliserer en forestilling om platformen som en teknologi, der er i stand til at fungere automatisk, og på den anden side må indgå i et krævende usynligt integrationsarbejde for at få den til at indfri de forventninger, kommunerne har til platformen. Hermed opretholdes forestillingen om teknologien som et teknisk og neutralt værktøj, som på ironisk vis både udgør en forudsætning og en mulig trussel for virksomhedens forretningsmodel. Herudover peger vi på, at der er et tillidsparadoks iboende i platformen, hvor screening og justering af indhold på en og samme tid er afgørende for at opretholde platformen som et trygt rum, hvor brugerne ikke oplever negative reaktioner på deres sårbarhed og åbenhed, men at virksomheden samtidig risikerer at bryde den tillid ved at redigere for meget i indholdet og hermed blive for synlig over for brugere og kommuner.

Published: December 2021

Artiklen omhandler et makerspace i Vancouver, Canada. Gennem empiriske eksempler fra eget feltarbejde i efteråret 2017 udforsker jeg, hvilke betydninger værktøj har for brugere af Vancouver Tool Library. Jeg argumenterer for, at værktøj foruden at være en fysisk teknologi også fremstår som en social teknologi, idet brugerne anvender det til at skabe mening og selverkendelse. Jeg konkluderer, at værktøjet, der lånes i Vancouver Tool Library, bliver tillagt særlig værdi, fordi det har forbindelse til makerspacet, og at dette har indflydelse på, hvordan brugerne forstår det. Værktøjet indgår herigennem i et hverdagspolitisk projekt, som brugerne løbende engagerer sig i gennem deres engagement i makerspacet.

METODER FOR EN FLERARTSANTROPOLOGI
Authors: Swanson Heather Anne 
Published: December 2021

Denne artikel argumenterer for, at flerartsantropologiens fokus på ikke-mennesker udgør en „mindre antropologi“, som udfordrer eksisterende antropologiske kategorier, men også disciplinens metoder. Med reference til mit studie af stillehavslaks undersøger jeg, hvordan og hvorfor antropologer kan og bør udforske de måder, hvorpå laks i samarbejde med naturvidenskabelige forskere „konstituerer“ verdener. I samarbejde med biologer undersøger jeg både lakseskæl og otolitter (øresten), hvis krystalliseringsmønstre fungerer som en slags dagbog, der materialiserer laksens vandringer og relationer. Med et antropologisk blik spørger jeg til, hvordan man kan bruge analysen af fiskeskæl og otolitter til at lære om, hvordan forskellige arter mødes på måder, som den klassiske etnografi ofte overser. Endelig viser jeg, hvordan antropologer kan engagere sig med naturvidenskabelige metodiske værktøjer, samtidig med at de bevarer en kritisk indstilling til, hvad disse værktøjer betyder for vores måder at skabe viden på.

Background
Invasive gibel carp, Carassius gibelio (Bloch, 1782) has become well-established in the Hungarian waters and now are spreading in the European waters. On major concern now is the potential hybridization between gibel carp and the other invasive species in the Carassius auratus complex (CAC), which may further accelerate the spread of the whole invasive species complex. The identification of gibel carp and their hybrids is difficult because of its morphological similarity to the other species in CAC. Here we carry out a genomic assessment to understand the history of gibel carp invasion and its phylogenetic relationship with the other species in CAC. Three loci of the mitochondrial genome (D-loop, CoI, Cytb) were used to determine the phylogenetic origin of individuals and relarionship among six gibel carp populations and the other species in the CAC.

Methodolgy
A total of 132 gibel carp samples from six locations in Southern Transdanubia (Hungary) were collected after phenotypic identification to measure the genetic diversity within and among gibel carp populations of Southern Transdanubia (Hungary). The genetic background was examined by the sequences of the mitochondrial genome: D-loop, Cytochrome c oxidase I (CoI) and Cytochrome b (Cytb). Mitochondrial genetic markers are excellent tools for phylogenetic studies because they are maternally inherited. Successfully identified haplotypes were aligned and with reference sequences in nucleotide databases (i.e., NCBI-BLAST: National Centre for Biotechnology Information and BOLD: Barcode of Life Data System). The phylogenetic relationships among gibel carp populations were then analyzed together with the reference sequences to understand the relationship and the level of hybridization with the species in CAC.

Results
Among the 132 aligned D-loop sequences 22 haplotypes were identified. Further examination of representative individuals of the 22 haplotypes, six Cytb and four CoI sequences were detected. The largest number of haplotypes of all three loci were found in Lake Balaton, the largest shallow lake in Central Europe. Based on the NCBI-BLAST alignment of the D-loop, haplotypes of Carassius auratus auratus and Carassius a. buergeri in CAC were identified in the C. gibelio samples. Further analysis of haplotypes with the other two mitochondrial markers confirmed the occurrence of intragenus hybridization of C. gibelio in the Hungarian waters.

Conclusion
By using three mitochondrial markers (D-loop, Cytb, CoI), we genomically characterized a gibel carp-complex in Hungarian waters and assessed the C. gibelio phylogenetic status between them. Hybrid origin of locally invasive Carassius taxon was detected in Hungary. It points out that invasive species are not only present in Hungary but reproduce with each other in the waters, further accelerating their spread.
Factors associated with psychosocial problems in Korean nursing and non-nursing students during the COVID-19 pandemic
Authors: Ha Jeongmin , Park Dahye 
Published: December 2021

Background
The coronavirus disease 2019 (COVID-19) pandemic has changed our lives in many ways, including school closures and social distancing practices. These abrupt life changes may have led to psychosocial problems in college students. This study aimed to identify the factors associated with psychosocial problems in South Korean nursing and non-nursing students.

Methods
This descriptive cross-sectional survey was conducted with 139 nursing and 147 non-nursing students (N = 286) between August 6 and October 30, 2020. We investigated participants’ general characteristics (that is, sociodemographic and health-promoting behaviors), sensitivity to COVID-19 infection, COVID-19 pandemic response indicators, and psychosocial problems. The factors associated with psychosocial problems were determined using multiple regression analysis.

Results
Among the COVID-19 pandemic response indicators, perceived health status during the COVID-19 pandemic was verified as a factor associated with psychosocial problems in nursing (β = − 5.831, p < .001) and non-nursing students (β = − 8.513, p < .001). Perceived stress (β = 1.263, p = .045), trust in policy (β = .892, p < .001), and religion (β = − 1.424, p = .004) were verified as correlates of psychosocial problems in non-nursing students.

Conclusion
As the COVID-19 pandemic continues, the stakeholders can use our study results to identify students experiencing psychosocial problems and subsequently as a theoretical background for developing intervention programs for those at a high risk of psychosocial problems. Additionally, it can be used as primary data for future research and practice regarding COVID-19 guidelines among students.

ObjectivePatients with rheumatoid arthritis (RA) are at an increased risk of acquiring infections owing to immunologic dysfunction and use of potent immunomodulatory medications; however, few data are available on their risk of COVID‐19. We estimated the rate of COVID‐19 among RA participants and compared it with that of the general population.MethodsUsing the Health Improvement Network, we identified RA patients before February 2020 and followed them to September 2020. We calculated the rate of COVID‐19 among participants with RA and compared it with that of the general population using a Cox proportional hazards model, adjusting for potential confounders using overlap weighting of exposure score. We repeated the same analysis among participants with osteoarthritis, a nonautoimmune rheumatic disease, as a negative control exposure.ResultsWe identified 225 cases of suspected and confirmed COVID‐19 among 17,268 RA patients, and 14,234 cases among 1,616,600 participants in the general population (1.4 versus 0.9/1,000 person‐months), with the adjusted hazard ratio (HRadj) being 1.19 (95% confidence interval [95% CI] 1.04–1.36). Confirmed COVID‐19 cases developed in 46 RA participants and in 2,249 in the general population (0.3 versus 0.1/1,000 person‐months), with the HRadj being 1.42 (95% CI 1.01–1.95). No statistically significant difference was observed for suspected and confirmed (HR 1.00 [95% CI 0.93–1.07]) or confirmed (HR 1.08 [95% CI 0.92–1.27]) COVID‐19 rates between participants with osteoarthritis and the general population.ConclusionRA, but not osteoarthritis, was associated with an increased risk of COVID‐19. Our findings provide timely evidence to support recommendations that booster vaccines and priority access to anti–SARS–CoV‐2 monoclonal antibody treatments should be encouraged for RA patients.

Published: December 2021

AbstractHydrogel‐based wearable electronic devices have received increasing attention. However, the construction of underwater strain sensors remains a significant challenge because of the swelling of hydrogels in an aquatic environment. This work presents the fabrication of an anti‐swellable hydrogel composed of polyvinyl alcohol (PVA), a copolymer of [2‐(methacryloyloxy) ethyl]dimethyl‐(3‐sulfopropyl) ammonium hydroxide (SBMA) and 2‐hydroxyethyl methacrylate. Interestingly, facile switch of the SBMA moiety from neutral to positively charged status at a low pH value leads to reduced osmotic pressure of the hydrogel for electrostatic repulsion‐driven elimination of water molecules and anti‐swelling. The resulting anti‐swellable hydrogel exhibits high toughness (518 kJ m−3) and compressive modulus (8.12 Mpa), ionic conductivity (up to 4.58 S m−1), and anti‐swelling behavior (equilibrium swelling ratio of 9% in water for 30 days). An underwater strain sensor based on this anti‐swellable hydrogel is further developed to monitor the movements of underwater sports. High sensitivity is achieved to identify multidirectional motions, including raising the head, swinging the arm, bending the elbow, knee and finger. Therefore, this study offers a facile strategy to generate hydrogel‐based sensors that can be adopted in an underwater environment as well as expands the potential applications of wearable electronic devices.
Mineral Hydrogel from Inorganic Salts: Biocompatible Synthesis, All‐in‐One Charge Storage, and Possible Implications in the Origin of Life

AbstractThis study reports a novel hydrogel synthesized using only water and the inorganic salts of FeCl3.6H2O and (NH4)6Mo7O24.4H2O, which offers a stable host for various ions (including Li+, Na+, Mg2+, Zn2+, Mn2+, or Ca2+), affording high ionic conductivity. More interestingly, the redox pair Fe2+/Fe3+ of the gel renders considerable pseudo‐capacitance, delivering a high volumetric energy density (4.8 mWh cm−3, based on the one‐piece half‐cell) and cycling stability. This simple one‐piece approach is convenient and effective—by pairing the mineral gel‐based half‐cell with another matching electrode, a novel type of charge storage device is formed, with the gel serving as one electroactive material, the electrolyte, and the membrane separator. Furthermore, the mineral hydrogel reported here is of low cytotoxicity, self‐bondable and healable, and highly resistant against swelling and disintegrating, with no collapse or volume expansion observed even after being soaked in water for 60 days. To our knowledge, this is the first time that mineral hydrogels have been synthesized from all‐inorganic agents in a fully biocompatible setting, which also sheds light on the myth‐ridden topic of pre‐cell evolution in the prebiotic age.
