Since late Mar. 2020, many universities halted normal operations due to the Coronavirus Disease 2019 (COVID-19) pandemic. Although extension uses many different techniques to educate consumers, it has been slow to grasp the power of social media. Faced with a dilemma of using digital methods instead of in-person field days, short courses, and workshops, Twitter was a viable alternative, especially for broad audience engagement. Tweet threads were posted on Twitter every Monday morning from 6 Apr. to 8 June 2020. Each thread consisted of 10 tweets. A hashtag #YardFruits was used to start the thread and for later reference. For the first nine threads only one fruit species was discussed per thread. The final thread consisted of single tweets of several species. Engagement percentage did not differ over time but did differ among the crop species. Tweets that did not include a photo received less engagement (2.7%) than those that did include a photo (4.7%). My Twitter account saw a 6.5% increase in followers during the series. Grape (Vitis sp.), passion fruit (Passiflora sp.), fig (Ficus carica), and pear (Pyrus communis) threads had the least engagement and were different from the Other Fruits thread. All other threads were similar. Extension educators can grow their influence by using well-targeted, focused tweets and tweet threads, especially those that use hashtags and photos.

Purpose Social media has become a vital part of any institute’s marketing plan. Social networks benefit businesses by allowing them to interact with their clients, grow brand exposure through offers and promotions and find new leads. It also offers vital information concerning the general emotions and sentiments directly connected to the welfare and security of the online community involved with the brand. Big organizations can make use of their social media data to generate planned and operational decisions. This paper aims to look into the conversion of sentiments and emotions over time. Design/methodology/approach In this work, a model called sentiment urgency emotion detection (SUED) from previous work will be applied on tweets from two different periods of time, one before the start of the COVID-19 pandemic and the other after it started to monitor the conversion of sentiments and emotions over time. The model has been trained to improve its accuracy and F1 score so that the precision and percentage of correctly predicted texts is high. This model will be tuned to improve results (Soussan and Trovati, 2020a; Soussan and Trovati, 2020b) and will be applied on a general business Twitter account of one of the largest chains of supermarkets in the UK to be able to see what sentiments and emotions can be detected and how urgent they are. Findings This will show the effect of COVID-19 pandemic on the conversions of the sentiments, emotions and urgencies of the tweets. Originality/value Sentiments will be compared between the two periods to evaluate how sentiments and emotions vary over time taking into consideration the COVID-19 as an affective factor. In addition, SUED will be tuned to enhance results and the knowledge that is mined when turning data into decisions is crucial because it will aid stakeholders handling the institute to evaluate the topics and issues that were mostly emphasized.

Flowering Intensity

The relationship between intensity of flowering and various aspects of cropping are reviewed for fruit species. Relatively light flowering can limit yield in most fruit species. This commonly occurs in young trees that have not achieved full production and in “off” years for varieties that display alternate bearing. When trees mature, many species will carry fruit numbers that exceed commercially desired levels, resulting in excessively small fruit and accentuating alternate bearing. The economic disadvantages of excess cropload have resulted in considerable research on fruit thinning and widespread commercial application of this practice. Heavy flowering intensity in some crop species results in economic disadvantages beyond the problems of excessive cropload and resultant small fruit size. Many species flower profusely and have initial fruit set that greatly exceeds tree capacity, resulting in abscission of numerous flowers and fruitlets. Abscised organs can represent a substantial amount of carbohydrates and nutrients, compromising availability of these materials at critical periods in flower and fruit development. The potential implications of this process are best exemplified in `Navel' orange [Citrus sinensis (L.) Osbeck], where an increase in flowering beyond intermediate intensity results in a reduction in both initial fruit set and final fruit yield at harvest. In several species, there is evidence that fruit size may be reduced by excessive flowering, even when cropload is quickly adjusted to an acceptable level. These data suggest that further research on the advantages of controlling flowering intensity is warranted.

Background: Patient education is a fundamental aspect of self-management of diabetes. The aim of this study was to understand whether a social media platform is a viable method to deliver education to people with diabetes and understand if people would engage and interact with it. Methods: Education sessions were provided via 3 platforms in a variety of formats. “Tweetorials” and quizzes were delivered on the diabetes101 Twitter account, a virtual conference via Zoom and video presentations uploaded to YouTube. Audience engagement during and after the sessions were analyzed using social media metrics including impressions and engagement rate using Twitter analytics, Tweepsmap, and YouTube Studio. Results: A total of 22 “tweetorial” sessions and 5 quizzes with a total of 151 polls (both in tweetorial and quiz sessions) receiving a total of 21,269 votes took place. Overall, the 1-h tweetorial sessions gained 1,821,088 impressions with an engagement rate of 6.3%. The sessions received a total of 2,341 retweets, 2,467 replies and 10,060 likes. The quiz days included 113 polls receiving 16,069 votes. The conference covered 8 topics and was attended live by over 100 people on the day. The video presentations on YouTube have received a total of 2,916 views with a watch time of 281 h and 8,847 impressions. Conclusion: Despite the limitations of social media, it can be harnessed to provide relevant reliable information and education about diabetes allowing people the time and space to learn at their own pace.

Social media offer the potential to facilitate two-way conversations needed for effective science communication; however, research communicators often struggle to reach lay audiences on these media. In this study, the Twitter and Instagram activity of four individual scientists in North America and Europe, acting as recognized science communicators, was compared with the activity of three marine-focused non-governmental organizations (NGOs), particularly paying attention to the strategies that encourage audience engagement in two-way conversations. The results show that a combination of interpersonal communication strategies can have an important effect on the level of lay user engagement in two-way conversations over time.

Material Identity

Accurate and reliable cultivar identification of crop species is essential to ensure plant material identity for registration and for cultivar protection. In this article, we proposed six simple sequence repeat (SSR) loci as a sufficient tool to characterize fig (Ficus carica L.) germplasm in Morocco maintained in an ex situ collection. A set of 17 microsatellite loci was used to characterize 75 accessions representing eight caprifigs, 51 local accessions, 11 foreign accessions, and five accessions of unknown origin. Eighty-five alleles with a mean number of six alleles per locus were observed in 62 distinct genotypes. Suspected synonyms and homonyms were confirmed, some of which maybe resulted from somatic mutation. Based on genetic criteria, including linkage disequilibrium, discrimination power, and molecular criteria as polymerase chain reaction conditions of loci multiplexing, we proposed a key identification set using six microsatellite markers to discriminate all genotypes present in the ex situ collection. Our selected SSR loci set can be used for larger genetic studies of fig germplasm, and a similar approach can be adopted for other fruit species.

This study is a systematic literature review of research on social media and political communication from political parties or politicians in parliament. The literature review is narrowed down further to focus on European studies. The review sorts studies into three thematic categories: political sender, citizen engagement and public actors. The study finds that papers are mostly pessimistic about the democratic influence of social media. This might be because studies have been looking for a social media revolution rather than slow evolution over time. The paper goes on to divide studies according to digital methods using digital trace data or traditional methods or a combination of both. The literature review presents the advantages of each approach and further highlights the potential of mixed and multiple methods. Finally, the literature review highlights recent issues with collecting data through platform API and argues that the field should be careful about relying too heavily on this collection approach in the future as social media platforms are starting to restrict access to digital trace data.

Encoding Genes

Date palm (Phoenix dactylifera) is one of the most widespread fruit crop species and can tolerate drastic environmental conditions that may not be suitable for other fruit species. Excess UV-B stress is one of the greatest concerns for date palm trees and can cause genotoxic effects. Date palm responds to UV-B irradiation through increased DEG expression levels and elaborates upon regulatory metabolic mechanisms that assist the plants in adjusting to this exertion. Sixty-day-old Khalas date palm seedlings (first true-leaf stage) were treated with UV-B (wavelength, 253.7 nm; intensity, 75 μW cm−2 for 72 h (16 h of UV light and 8 h of darkness). Transcriptome analysis revealed 10,249 and 12,426 genes whose expressions were upregulated and downregulated, respectively, compared to the genes in the control. Furthermore, the differentially expressed genes included transcription factor-encoding genes and chloroplast- and photosystem-related genes. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to detect metabolite variations. Fifty metabolites, including amino acids and flavonoids, showed changes in levels after UV-B excess. Amino acid metabolism was changed by UV-B irradiation, and some amino acids interacted with precursors of different pathways that were used to synthesize secondary metabolites, i.e., flavonoids and phenylpropanoids. The metabolite content response to UV-B irradiation according to hierarchical clustering analysis showed changes in amino acids and flavonoids compared with those of the control. Amino acids might increase the function of scavengers of reactive oxygen species by synthesizing flavonoids that increase in response to UV-B treatment. This study enriches the annotated date palm unigene sequences and enhances the understanding of the mechanisms underlying UV-B stress through genetic manipulation. Moreover, this study provides a sequence resource for genetic, genomic and metabolic studies of date palm.

Investigations at sites across northwestern Honduras—inside and outside the Maya area—have revealed diverse food activities and ingredients. Paralleling the evidence from durable artifact assemblages, we see transformation over time in materials and practices, as well as the movement of elements across the landscape. Botanical evidence points toward a dynamic overlap between northern and southern societies, with northwestern Honduras serving as a sort of regional crossroads. In this article, we compare cuisines from several ancient communities in northwestern Honduras, using microbotanical and macrobotanical residues. We briefly address the political and historic context of the region and provide abridged biographies of several culinary taxa. Of particular interest are milpa annual crops such as maize and squash, managed and cultivated palm species, wild and managed herbaceous species, edible fruit species, and root and tuberous crops such as lerén, sweet potato, and manioc.

In the small demonstration orchard of the College Faculty of Horticulture at Kecskemét the blooming time, the flower density and the honeybee activity was observed at a number of cultivars of 20 flower species during four consecutive years. Fruit crop species were in flower during 3-4 months altogether. The blooming period of them was classified into five groups as early (almond, apricot, gooseberry), middle early (sweet cherry, red currant, currant-gooseberry, black currant, white currant, peach, plum, sour cherry), middle late (pear, strawberry, apple), late (black elder, quince, medlar, raspberry, blackberry-raspberry) and very late blooming period (blackberry). The blooming period of the members of the groups of early and medium early blooming often coincided partly and the same happened between the medium and the medium late as well as between fruits of late and very late flowering. The flower density of some fruit species is extremely variable (currant-gooseberry, medlar), while at others it is fairly stable and evenly dense in consecutive years (sour cherry, sweet cherry, strawberry). At other fruit species it is moderately changeable. Some fruit species tended to attract more honeybees than others (plum, apple, quince, medlar) and some of them tended to attract much less (black elder, pear) but most species can be regarded as of medium attractivity. On the flowers of some fruit species (pear, strawberry, quince) honeybees gathered pollen predominantly. At most fruit species however pollen and nectar gathering behaviour seemed to be gradually changing during the season. Namely most honeybees tended to gather pollen at the flowers of the early blooming fruit species, but on the other hand typical foraging behaviour gradually shifted to nectar gathering at the flowers of fruit species of moderate and late blooming periods.

Med afsæt i henholdsvist den amerikanske offentlighedssociologi fra den første halvdel af det 20. Århundrede – samt den vigtigste litteratur indenfor digitale metoder – vil denne artikel fremføre to argumenter. Det første argument er, at offentligheder ikke kan begrebsliggøres isoleret fra de materielle omstændigheder, der giver dem synlighed for sig selv og andre. Det andet argument er, at infrastrukturen omkring digitale spor og digitale metoder åbner for muligheden af at synliggøre – og dermed også begrebsliggøre – den offentlige debat ud fra et mere relationelt of processuelt perspektiv end f.eks. spørgeskemaundersøgelsen. Med afsæt i disse to argumenter introducerer artiklen fire principper, der kan være med til at guide anvendelsen af digitale metoder til at forstå offentlighedsdannelser i en digitalt medieret tid. De fire principper er a) at følge sagsdrevne offentligheder, b) se distinktioner nede fra de symboler, der udveksles af disse offentligheder, c) tage borgeres netværkspositioner med i vurderingen af deres meningers effekt og d) at være opmærksom på temaers intensitet og omskiftelighed over tid. Den praktiske konsekvenser af at følge disse principper vises gennem empiriske erfaringer fra et nyligt overstået datasprint med Teknologirådet. ENGELSK ABSTRACT: Anders Koed Madsen: Data­Publics – reflections on digital methods in the light of early American pragmatism This article introduces two arguments concerning discussions of digital methods. They are based on US public sociology from the first half of the 20th century and the most important literature within the field of digital methods. The first argument is that publics cannot be understood in isolation from the material conditions that give them visibility both for themselves (intra-public visibility) and for others. The second argument posits that the infrastructure of digital traces and digital methods affords visualizing and conceptualizing public debate from a relational and procedural perspective rather than from employing a questionnaire survey. The article introduces four principles that can help guide the use of digital methods to understand publics in a digitally mediated era. They are: a) follow issue publics, b) use the analytical distinctions from the symbols exchanged by these publics, c) take into account the network positions of citizens when assessing the impact of their opinion, and d) be aware of the intensity and interchangeability of themes over time. The practical consequences following these principles are shown through empirical experiences from a recently held data sprint with the Danish Board of Technology. Keywords: Digital methods, pragmatism, Chicago-school, publics, surveys, Lazarsfeldt.
