Prediction of Shooting Events in Soccer Videos Using Complete Bipartite Graphs and Players’ Spatial-Temporal Relations
Authors: Goka Ryota , Moroto Yuya , Maeda Keisuke , Ogawa Takahiro , Haseyama Miki
Published: May 2023

In soccer, quantitatively evaluating the performance of players and teams is essential to improve tactical coaching and players’ decision-making abilities. To achieve this, some methods use predicted probabilities of shoot event occurrences to quantify player performances, but conventional shoot prediction models have not performed well and have failed to consider the reliability of the event probability. This paper proposes a novel method that effectively utilizes players’ spatio-temporal relations and prediction uncertainty to predict shoot event occurrences with greater accuracy and robustness. Specifically, we represent players’ relations as a complete bipartite graph, which effectively incorporates soccer domain knowledge, and capture latent features by applying a graph convolutional recurrent neural network (GCRNN) to the constructed graph. Our model utilizes a Bayesian neural network to predict the probability of shoot event occurrence, considering spatio-temporal relations between players and prediction uncertainty. In our experiments, we confirmed that the proposed method outperformed several other methods in terms of prediction performance, and we found that considering players’ distances significantly affects the prediction accuracy.

Published: May 2023

This paper explores how group preferences develop among children living in the post-conflict context of Kosovo and how this development shapes children’s willingness to be close to their outgroup peers among the segregated majority (ethnic Albanian) and minority (ethnic Serb) members. The study was conducted in four ethnically divided primary schools, with 220 participants aged 6–10. Children played a series of games and tasks which measured ethnic ingroup preference, preference for the Kosovar flag, and willingness to be close to ethnic outgroup children. Children in this context where a new national Kosovar identity is developing following independence display very high ethnic ingroup preferences. Kosovar Serb children showed low willingness to engage with outgroup members and remained constant with age, while Kosovar Albanian children’s willingness to engage with the outgroup was present among younger children but diminished with age. Results add to the literature on the underlying process by which identity develops among segregated majority and minority who have little or no opportunities to interact. Lack of intergroup contact hinders the development of more positive intergroup relations. To build a peaceful coexistence, programs which connect the segregated schools and facilitate intergroup contact, especially among the younger age groups, are recommended.

Published: May 2023

During the COVID-19 pandemic, higher education students were reported as one of the most affected in terms of wellbeing. In the current study, we explored higher education students’ self-perceptions on why and how their mental wellbeing was affected by the COVID-19 pandemic and its related measures. Focus group discussions with potentially vulnerable university student groups, as well as university staff, revealed that the students described the pandemic as a period of reduced mental wellbeing. Overall, students identified two main reasons for this: the lingering aspect of the pandemic and restricted social contact and support. Moreover, we identified several underlying factors of specific student groups’ vulnerability in terms of wellbeing: entering the university during the COVID-19 pandemic and students’ living situation, employment status, financial stress, and home environment. Moreover, as a potential mitigating factor, the availability of university facilities during the COVID-19 pandemic emerged as beneficial for students’ mental wellbeing. Our results indicate the importance of universities acting as social spaces that facilitate connection and peer support and, thus, working preventively towards the improved mental wellbeing of students. Furthermore, university support in providing facilities to increase inclusivity should be organized or improved.

Published: May 2023

This paper deals with COVID-19-hit Kenyan slums and the numerous interventions civil society organizations implemented during the first waves of the pandemic since it was initially detected in March 2020. As part of a comprehensive project using mixed methodology, including desk research and key informant interviews, community-based organizations and non-governmental organizations, together with other stakeholders of their collaborative networks, were investigated regarding the roles that they played, the projects they carried out, and the interventions they were involved in in the mitigation of the negative impacts of COVID-19. This paper investigates how COVID-19 actually hit Kenyan slums and how it affected civil society organizations during the pandemic.
The Optimal Deployment Strategy of Mega-Constellation Based on Markov Decision Process
Authors: Wang Xuefeng , Zhang Shijie , Zhang Hongzhu
Published: May 2023

LEO satellite mega-constellation projects have been proposed by many countries or commercial organizations in recent years. With more than 2000 satellites launched by SpaceX to configure the Starlink system, the orbital resources are more constrained given the existence of spacecrafts and countless orbital debris. Due to this, the operating environment is full of uncertainty and information symmetry is absent for designers and stakeholders during the process of project deployment. The flux model of space debris on orbit has been built for assessing the LEO operation environment. Based on the orbital debris flux model, the collision probability can be calculated, which is an important variable of the state space. Given the condition that tge number of satellites decreases due to collision between satellites and debris, the Markov decision model has been built for optimal deployment strategy and decision-making. In order to assure that the mega-constellation system could provide services when satellites have failed, additional satellites need to be launched. The optimal deployment is the decision to launch a moderate number of satellites to maximize the benefit and minimize the cost. Assuming that at least 30 satellites need to be operated, 4 deployment scenarios are considered and the optimal deployment strategies can be obtained.

Herein, male juvenile rats (23th postnatal days (PND)) were exposed to chlorpyrifos (CPS) (7.5 mg/kg b.wt) and/or iprodione (IPD) (200 mg IPD /kg b.wt) until the onset of puberty (60th day PND). Our results demonstrated that IPD and/or CPS exposure considerably reduced locomotion and exploration. However, CPS single exposure induced anxiolytic effects. Yet, neither IPD nor IPD + CPS exposure significantly affected the anxiety index. Of note, IPD and/or CPS-exposed rats showed reduced swimming time. Moreover, IPD induced significant depression. Nonetheless, the CPS- and IPD + CPS-exposed rats showed reduced depression. The individual or concurrent IPD and CPS exposure significantly reduced TAC, NE, and AChE but increased MDA with the maximum alteration at the co-exposure. Moreover, many notable structural encephalopathic alterations were detected in IPD and/or CPS-exposed rat brain tissues. The IPD + CPS co-exposed rats revealed significantly more severe lesions with higher frequencies than the IPD or CPS-exposed ones. Conclusively, IPD exposure induced evident neurobehavioral alterations and toxic reactions in the brain tissues. IPD and CPS have different neurobehavioral effects, particularly regarding depression and anxiety. Hence, co-exposure to IPD and CPS resulted in fewer neurobehavioral aberrations relative to each exposure. Nevertheless, their simultaneous exposure resulted in more brain biochemistry and histological architecture disturbances.

Published: May 2023

Chromium (Cr) is an expression toxic metal and is seriously released into the soil environment due to its extensive use and mining. Basalt is an important Cr reservoir in the terrestrial environment. Cr in paddy soil can be enriched by chemical weathering. Therefore, basalt-derived paddy soils contain extremely high concentrations of Cr and can enter the human body through the food chain. However, the water management conditions’ effect on the transformation of Cr in basalt-derived paddy soil with high geological background values was less recognized. In this study, a pot experiment was conducted to investigate the effects of different water management treatments on the migration and transformation of Cr in a soil–rice system at different rice growth stages. Two water management treatments of continuous flooding (CF) and alternative wet and dry (AWD) and four different rice growth stages were set up. The results showed that AWD treatment significantly reduced the biomass of rice and promoted the absorption of Cr in rice plants. During the four growth periods, the root, stem and leaf of rice increased from 11.24–16.11 mg kg−1, 0.66–1.56 mg kg−1 and 0.48–2.29 mg kg−1 to 12.43–22.60 mg kg−1, 0.98–3.31 mg kg−1 and 0.58–2.86 mg kg−1, respectively. The Cr concentration in roots, stems and leaves of AWD treatment was 40%, 89% and 25% higher than CF treatment in the filling stage, respectively. The AWD treatment also facilitated the potential bioactive fractions conversion to the bioavailable fraction, compared with the CF treatment. In addition, the enrichment of iron-reducing bacteria and sulfate-reducing bacteria with AWD treatment also provided electron iron for the mobilization of Cr, thus affecting the migration and transformation of Cr in the soil. We speculated that the reason for this phenomenon may be the bioavailability of Cr was affected by the biogeochemical cycle of iron under the influence of alternating redox. This indicates that AWD treatment may bring certain environmental risks in contaminated paddy soil with high geological background, and it is necessary to be aware of this risk when using water-saving irrigation to plant rice.
Communication Interventions and Assessment of Drivers for Hendra Virus Vaccination Uptake
Authors: Kropich-Grant Jessica N. , Wiley Kerrie E. , Manyweathers Jennifer , Thompson Kirrilly R. , Brookes Victoria J.
Published: May 2023

Hendra virus disease (HeVD) is an emerging zoonosis in Australia, resulting from the transmission of Hendra virus (HeV) to horses from Pteropus bats. Vaccine uptake for horses is low despite the high case fatality rate of HeVD in both horses and people. We reviewed evidence-based communication interventions to promote and improve HeV vaccine uptake for horses by horse owners and conducted a preliminary evaluation of potential drivers for HeV vaccine uptake using the Behavioural and Social Drivers of Vaccination (BeSD) framework developed by the World Health Organization. Six records were eligible for review following a comprehensive search and review strategy of peer-reviewed literature, but evidence-based communication interventions to promote and improve HeV vaccine uptake for horses were lacking. An evaluation of potential drivers for HeV vaccine uptake using the BeSD framework indicated that horse owners’ perceptions, beliefs, social processes, and practical issues are similar to those experienced by parents making decisions about childhood vaccines, although the overall motivation to vaccinate is lower amongst horse owners. Some aspects of HeV vaccine uptake are not accounted for in the BeSD framework (for example, alternative mitigation strategies such as covered feeding stations or the zoonotic risk of HeV). Overall, problems associated with HeV vaccine uptake appear well-documented. We, therefore, propose to move from a problems-focused to a solutions-focused approach to reduce the risk of HeV for humans and horses. Following our findings, we suggest that the BeSD framework could be modified and used to develop and evaluate communication interventions to promote and improve HeV vaccine uptake by horse owners, which could have a global application to promote vaccine uptake for other zoonotic diseases in animals, such as rabies.

Published: May 2023

Lipid nanoparticles (LNPs) are widely used as delivery systems for mRNA vaccines. The stability and bilayer fluidity of LNPs are determined by the properties and contents of the various lipids used in the formulation system, and the delivery efficiency of LNPs largely depends on the lipid composition. For the quality control of such vaccines, here we developed and validated an HPLC-CAD method to identify and determine the contents of four lipids in an LNP-encapsulated COVID-19 mRNA vaccine to support lipid analysis for the development of new drugs and vaccines.
BBIBP-CorV Vaccination against the SARS-CoV-2 Virus Affects the Gut Microbiome

Published: May 2023

Several observational studies have confirmed that the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) might substantially affect the gastrointestinal (GI) system by replicating in human small intestine enterocytes. Yet, so far, no study has reported the effects of inactivated SARS-CoV-2 virus vaccines on gut microbiota alterations. In this study, we examined the effects of the BBIBP-CorV vaccine (ChiCTR2000032459, sponsored by the Beijing Institute of Biological Products/Sinopharm), on gut microbiota. Fecal samples were collected from individuals whoreceived two doses of intramuscular injection of BBIBP-CorV and matched unvaccinated controls. DNA extracted from fecal samples was subjected to 16S ribosomal RNA sequencing analysis. The composition and biological functions of the microbiota between vaccinated and unvaccinated individuals were compared. Compared with unvaccinated controls, vaccinated subjects exhibited significantly reduced bacterial diversity, elevated firmicutes/bacteroidetes (F/B) ratios, a tendency towards Faecalibacterium-predominant enterotypes, and altered gut microbial compositions and functional potentials. Specifically, the intestinal microbiota in vaccine recipients was enriched with Faecalibacterium and Mollicutes and with a lower abundance of Prevotella, Enterococcus, Leuconostocaceae, and Weissella. Microbial function prediction by phylogenetic investigation of communities using reconstruction of unobserved states (PICRUSt) analysis further indicated that Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways involved in carbohydrate metabolism and transcription were positively associated with vaccine inoculation, whereas capacities in neurodegenerative diseases, cardiovascular diseases, and cancers were negatively affected by vaccines. Vaccine inoculation was particularly associated with gut microbiota alterations, as was demonstrated by the improved composition and functional capacities of gut microbiota.

The Community Preventive Services Task Force endorses vaccination programs in schools to increase access to vaccinations. However, implementing a school-based approach requires substantial coordination, planning, and resources. All for Them (AFT) is a multilevel, multicomponent approach to increase HPV vaccination among adolescents attending public schools in medically underserved areas in Texas. AFT comprised a social marketing campaign, school-based vaccination clinics, and school nurse continuing education. Process evaluation metrics and key informant interviews to understand experiences with AFT program implementation informed lessons learned. Lessons emerged in six domains: strong champion, school-level support, tailored and cost-effective marketing approaches, mobile provider collaboration, community presence, and crisis management. Strong support at district and school levels is vital for gaining principal and school nurse buy-in. Social marketing strategies are integral to program implementation and should be adjusted to maximize their effectiveness in motivating parents to vaccinate children against HPV, which also can be achieved through increased community presence of the project team. Preparing contingency plans and flexibility within the program can facilitate appropriate responses to provider restrictions in mobile clinics or in the event of unforeseen crises. These important lessons can offer useful guidelines for the development of prospective school-based vaccination programs.
COVID-19 Vaccine Coverage in India: A District-Level Analysis
Authors: Agarwal Sandip K. , Naha Maharnab
Published: May 2023

India implemented the largest COVID-19 vaccination drive in the world, through which it vaccinated the majority of its population. Lessons from the Indian COVID-19 vaccination experience can be invaluable for other LMICs as well as for preparedness for future outbreaks. Our study is designed to explore the factors associated with COVID-19 vaccination coverage in India at the district level. We used data from COVID-19 vaccination in India combined with several other administrative data to create a unique data set that facilitated a spatio–temporal exploratory analysis by uncovering the factors associated with vaccination rates across different vaccination phases and districts. We found evidence that past reported infection rates were positively correlated with COVID-19 vaccination outcomes. Past cumulative COVID-19 deaths as a proportion of district populations were associated with lower COVID-19 vaccination, but the percentage of past reported infection was positively correlated with first-dose COVID-19 vaccination, which might indicate a positive role of higher awareness created by a higher reported infection rate. Districts that on average had a higher population burden per health centre were likely to have lower COVID-19 vaccination rates. Vaccination rates were lower in rural areas relative to urban areas, whereas the association with literacy rate was positive. Districts with a higher percentage of children with complete immunisation were associated with higher COVID-19 vaccination, whereas low vaccination was observed in districts that had higher percentages of wasted children. COVID-19 vaccination was lower among pregnant and lactating women. Higher vaccination was observed among populations with higher blood pressure and hypertension (which were a few of the co–morbidities associated with COVID-19 infection).

Published: May 2023

Pruritic models in healthy dogs utilizing intravenous administration of interleukin 31 (IL-31) bypass the “natural” itch sensation in AD, which is initiated by pruriceptive primary afferent neurons in the skin. This study aimed to evaluate the immediate/delayed pruritus responses and the pruritic behaviors observed in an intradermal IL-31-induced pruritic model of healthy dogs and the anti-pruritic effect of oclacitinib on said model. In Phase 1, all the dogs were randomized and video-recorded for 300 min after intradermal canine recombinant IL-31 injections (1.75 µg/kg) and vehicle (phosphate-buffered saline) injections. In Phase 2, all the dogs received oral oclacitinib (0.4–0.6 mg/kg, twice daily for 4 consecutive days and once daily on day 5), with the intradermal IL-31 injection performed on day 5. Two blinded investigators reviewed the pruritic behaviors in all the video recordings. Intradermal IL-31 administration to healthy dogs caused a significant increase in the total (p = 0.0052) and local (p = 0.0003) seconds of pruritic behavior compared to the vehicle control. Oral oclacitinib administration significantly reduced the total (p = 0.0011) and local (p = 0.0156) intradermal IL-31-induced pruritic seconds; there was no significant difference in pruritic seconds between the vehicle and oclacitinib within the IL-31 groups. Significant delayed pruritic responses at 150–300 min after IL-31 injections were observed, and intradermal IL-31 failed to induce acute itch (first 30 min). Intradermal injection of IL-31 induces delayed itch responses in dogs that are diminished by the effect of oclacitinib, an oral JAK inhibitor.

At present, there are no data on the presence of bacteria in healthy canine and feline pregnancies at term. Here, we investigated the uterine microbiome in bitches (n = 5) and queens (n = 3) undergoing elective cesarean section in two facilities. Samples included swabs from the endometrium, amniotic fluid, and meconium, and environmental swabs of the surgical tray as controls. Culture and 16S rRNA gene sequencing were used to investigate the presence of bacteria. Culture was positive for 34.3% of samples (uterus n = 3, amniotic fluid n = 2, meconium n = 4, controls n = 0), mostly with low growth of common contaminant bacteria. With sequencing techniques, the bacterial abundance was significantly lower than in environmental controls (p < 0.05). Sequencing results showed a species-specific pattern, and significant differences between canine and feline bacterial populations were found at order, family, and genus level. No differences were found in alpha and beta diversities between feto-maternal tissues and controls (p > 0.05). Dominant phyla were Bacteroidetes, Firmicutes, and Proteobacteria in different proportions based on tissue and species. Culture and sequencing results suggest that the bacterial biomass is very low in healthy canine and feline pregnancies at term, that bacteria likely originate from contamination from the dam’s skin, and that the presence of viable bacteria could not be confirmed most of the time.

Published: May 2023

In creative work, happy findings sometimes happen. They appear unconsciously, which is characteristic of art. Music for a composer is an opportunity to record the listener’s mood in notes and convey it with music. The creation of the song "Green Jackets" took place when feeling the romance of the Far East. Every summer, students from various universities of the country filled the Far Eastern construction sites and made an unusual atmosphere of creativity and creative environment. The author of this article worked at the higher educational institution and was among the students. At that time, he himself had recently graduated from the conservatory majoring in composition. It was the beginning of a creative path and youth, which is capable of much. The student song "Green Jackets" was written in 1968. It was dedicated to the 50th anniversary of the Komsomol and the All-Union movement of student construction teams. In student construction teams, 800,000 students wore green jackets every summer. They did a huge amount of construction work. This was especially important for remote and sparsely populated areas of the Far East. The song "Green Jackets" turns 55 this year. It is known that there are people, students of the 1960s and 1970s, who gather together and still sing it. This means only one thing: the song sunk into the soul. The authors managed to capture the special atmosphere of the time in words and music. The specificity of the creative process and the process of creating a work are revealed in this article.
The Ministry of Industry and Trade proposed to expand the list of labeled clothing
Authors:   Rostest Ural CA, Kurbatova E.D.
Published: May 2023

The Ministry of Industry and Trade of the Russian Federation has made a proposal to significantly expand the list of light industry goods subject to labeling. It is mandatory to label clothes made of artificial fur, as well as jackets and other products, it is planned from 01.06.2023. The operator of the CRPT, which ensures the operation of the IS "Honest SIGN", believes that there is a need to expand the list of marked clothing, due to repeated appeals from representatives of well-known business communities associated with the production of this product category. The reason is that the Russian market regularly faces the problem of illegal turnover of light industry products. One of such illegal actions is the importation of natural fur products by importers to Russia under the guise of artificial fur products.

Published: May 2023

Background:

Preference-concordant care is a cornerstone of high-quality medical decision-making, yet the prevalence and correlates of preference-concordant care have not been well-studied in patients receiving dialysis. We surveyed hospitalized people receiving maintenance dialysis to estimate the prevalence and correlates of preference-concordant care among this population.

Methods:

We assessed preference concordance by asking participants (223/380, 59% response rate), “How strongly do you agree or disagree that your current treatment plan meets your preference?” We assessed treatment plan preference by asking if patients preferred a plan that focused on (a) extending life, or (b) relieving pain and discomfort. We assessed shared dialysis decision-making using the 9-item Shared Decision-Making Questionnaire (SDM-Q-9). We examined the differences between those reporting lack of preference-concordant care to those reporting receipt of preference-concordant care using chi-square analyses. We also studied whether patients’ treatment plan preferences or shared dialysis decision-making scores were correlated with their likelihood of receiving preference-concordant care.

Results:

Of the 213 respondents who provided data on preference-concordance, 90 (42.3%) reported that they were not receiving preference-concordant care. Patients who preferred pain and discomfort relief over life extension were less likely {OR 0.15 (95% CI 0.08, 0.28) P =<0.0001} to report receiving preference-concordant care; patients with higher shared decision-making scores were more likely {OR 1.02 [95% CI 1.01, 1.03], P=0.02} to report preference-concordant care.

Conclusions:

A substantial proportion of this sample of hospitalized people receiving maintenance dialysis reported not receiving preference-concordant care. Efforts to improve symptom management and enhance patient engagement in dialysis decision-making may improve the patients’ perceptions of receiving preference-concordant care.
Interações medicamentosas em pacientes idosos polimedicados

Published: May 2023

Este estudo tem como objetivo abordar as interações medicamentosas causadas pela polifarmácia em pacientes idosos. As interações medicamentosas são modificações dos efeitos de um ou mais fármacos, podendo levar a uma diminuição da eficácia do tratamento e o aparecimento de efeitos indesejáveis. Alguns fatores contribuem para que ocorram as interações medicamentosas em pacientes idosos, como fatores fisiológicos e patológicos, uma vez que o organismo do idoso apresenta alterações farmacocinéticas nos níveis de absorção, distribuição, metabolização, e principalmente de eliminação dos fármacos, o que pode acarretar acúmulo de metabolitos tóxicos para o paciente e efeitos colaterais, podendo levar a hospitalização ou morte. Também podem ocorrer alterações farmacodinâmicas, seja por um efeito sinérgico, onde o medicamento tem sua ação potencializada interagindo com um outro medicamento, ou efeito antagônico diminuindo o efeito do fármaco, ou inibindo a sua ação total. Dessa forma, a análise da prescrição e intervenção farmacológica é importantíssima e consiste numa avaliação sistemática dos riscos e benefícios potenciais de cada fármaco, visto a vulnerabilidade dos pacientes idosos acometidos pela polifarmácia.

A demanda por novos materiais torna necessário o desenvolvimento de métodos de análise microestrutural para avaliar as propriedades dos materiais. O objetivo deste trabalho é o desenvolvimento de um software que, por intermédio da aquisição e do tratamento de dados, correlaciona a condutividade elétrica e a microestrutura de um material. Para isso, foi construído um software em LabVIEW que recebe tanto as informações geométricas da amostra quanto sobre as medidas de tensão obtidas por um voltímetro de alta precisão, a fim de transformar esses dados em medidas de condutividade elétrica. Para avaliar o software, foi realizada a preparação, análise metalográfica e a medição da condutividade elétrica de duas amostras de aço livre de intersticiais (IF): laminada e tratada termicamente. A partir das micrografias obtidas pelo microscópio óptico e dos valores de condutividade encontrados pelo software, observou-se que a condutividade calculada estava coerente com a microestrutura das amostras.

O morango é um dos frutos mais consumidos mundialmente e possui atributos químicos que influenciam em suas características organolépticas. Foram analisados seis cultivares de morangueiro comumente consumidos no Brasil (Albion, Aromas, Camarosa, Camino Real, Monterey, Sweet Charlie) cultivados sob as mesmas condições em solo na área de Olericultura da Universidade Estadual do Centro Oeste, localizado na cidade de Guarapuava/Paraná, e posteriormente quantificados em relação a teores de doçura, acidez total titulável e pH em triplicata, totalizando a análise com18 frutos. O estudo foi dividido em delineamento inteiramente casualizados (DBC), e os dados submetidos a teste ANOVA para análise de variância e as médias comparadas pelo teste Tukey a 5% de probabilidade. Pode-se observar de que o cultivar Sweet Charlie se destacou frente aos demais cultivares, em relação a todos as características analisadas, contudo o cultivar o Albion apresentou menor doçura de fruto, e o cultivar Aromas menores valores em relação ao pH e acidez total titulável.

The aim of this research was to study water absorption and dimensional stability of shoe insoles. The dimensional stability was indicated by swelling, increase in size of the sample, and shrinkage. Tests were performed ac­cording to the relevant ISO standards. Eight shoe insoles with different compositions were used in the experiment. The experimental results have shown that the water absorption ability of insoles is influenced by the composition and structure of insole components. The statistical analysis of the experimental results has shown a positive linear correlation between water absorption of insole and their swelling, and a negative linear correlation between swelling and increase in size of the samples. The shrinkage of all eight insoles was less than 1%.
A Case Study of YouTuber’s use of Twitter for Consumer Engagement
Authors: Zhang Hantian
Published: May 2023

Twitter as a popular social media site has become a widely used platform for brands to establish consumer engagement (CE), a connection between firms and consumers beyond product consumption and purchase. CE is important for brands to build a long-standing relationship with consumers, leading to positive marketing outcomes. Meanwhile, famous YouTubers, who have obtained large fanbases also use Twitter to connect with their viewers beyond the YouTube platform, as a part of their self-branding process. Existing studies found various strategies brands use to engage consumers on Twitter. Studies on individual users and other celebrities also found that they implement similar factors as brands for engaging their followers, suggesting the application of CE from organisations to individual bases on Twitter. However, while it can be argued that as personal brands, YouTubers also implement similar CE strategies as traditional brands on Twitter to engage their viewers as their consumers, little research has explicitly explored the CE factors implemented by YouTubers on Twitter. Therefore, by adapting the concept of CE, this research explores “How do YouTubers use Twitter for consumer engagement?”.  The research implemented a qualitative case study on UK beauty vlogger Zoe Sugg (Zoella)’s Twitter account. In the study, a qualitative content analysis was performed on over 3000 tweets collected from Sugg’s Twitter via API to identify strategies implemented by Sugg that can be seen as CE factors that are also used by brands. The results show that like other brands, Sugg uses various CE factors, including interaction, information offers, topical messages, rewards, and visual elements on Twitter to engage her viewers. The research proposes that CE strategies that are used by traditional brands are also implemented by YouTubers and similar online personalities for engaging audiences on Twitter. The research contributes to understanding the building of YouTube-viewer relationships from the perspective of achieving CE on social media sites beyond YouTube.
Resale HDB Price Prediction Considering Covid-19 through Sentiment Analysis
Authors: Anbu Durai Srinaath
Published: May 2023

Twitter sentiment has been used as a predictor to predict price values or trends in both the stock market and housing market. The pioneering works in this stream of research drew upon works in behavioural economics to show that sentiment or emotions impact economic decisions. Latest works in this stream focus on the algorithm used as opposed to the data used. A literature review of works in this stream through the lens of data used shows that there is a paucity of work that considers the impact of sentiments caused due to an external factor on either the stock or the housing market. This is despite an abundance of works in behavioural economics that show that sentiment or emotions caused due to an external factor impact economic decisions. To address this gap, this research studies the impact of Twitter sentiment pertaining to the Covid-19 pandemic on resale Housing Development Board (HDB) apartment prices in Singapore. It leverages SNSCRAPE to collect tweets pertaining to Covid-19 for sentiment analysis, lexicon-based tool, VADER, is used for sentiment analysis, Granger Causality is used to examine the relationship between Covid-19 cases and the sentiment score, and neural networks are leveraged as prediction models. Twitter sentiment pertaining to Covid-19 as a predictor of HDB price in Singapore is studied in comparison with the traditional predictors of housing prices i.e., the structural and neighbourhood characteristics. The results indicate that using Twitter sentiment pertaining to Covid-19 leads to better prediction than using only the traditional predictors and performs better as a predictor compared to two of the traditional predictors. Hence, Twitter sentiment pertaining to an external factor should be considered as important as traditional predictors. In a micro sense, this paper demonstrates the use of sentiment analysis of Twitter data in urban economics. In a macro sense, the paper demonstrates the extent to which social media is able to capture the behavioral economic cues of a population.
