An increasing percentage of US waste methane (CH4) emissions come from wastewater treatment (10% in 1990 to 14% in 2019), although there are limited measurements across the sector, leading to large uncertainties in current inventories. On behalf of all authors, the corresponding author states that there is no conflict of interest. The concerns about distance learning and its future applications (topic 2) gained importance in the latter stages of 2021, while the first and third topics, which were ranked highly at first, started a steep descent in the last part of the period.

Sentiment analysis of Arabic tweets regarding distance learning in Saudi Arabia during the COVID-19 pandemic. 2 second following time and distance (minimum when conditions are ideal and you are paying close attention. Illustration showing longitude convergence. The stemming algorithms that aggressively reduce words to a common base even if these words actually have different meanings are not considered here. Psychol. 4 seconds is proven to be the adequate distance to prevent crashes,. By using topic numbers k ranging from 2 to 10, we initialized the LDA models and calculated the model coherence. As a part of the probabilistic topic model class, the dynamic model can explain how various tweet themes evolve. 4) for all regions except for Umbria (\(+\) 0.10), Sardinia (\(+\) 0.07) and Veneto ( 0.06), which slightly exceed the neutrality thresholds. Therefore, the VADER and nrc methods are not comparable in terms of the number of tweets and polarity categories. 4-month full-time program; Med. = 15 ? The choice of 4 or 7 topic numbers would lead to a nonuniform distribution on primer component analysis (PCA), which means that there is not a high degree of independence for each topic. With the aim of studying the opinions and emotions of Italians regarding distance learning, we collected tweets on this issue and carried out a sentiment analysis using the VADER and syuzhet packages.

It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero. This paper presents a review of the research progress and practical application of emergency plan construction in China over the past two decades by using the literature analysis method and the case analysis method. Using this mathematical notation, the hypotheses can now be evaluated using statistical tools. & Lafferty, J. Psychol. when you are preparing to slow down you should check for traffic behind you.

Overall, the probability of a document (or tweet, in our case) \(\mathbf {w}\) containing words can be described as: Finally, the probability of the corpus of M documents \(D=\{\mathbf{w}_\mathbf{1},\ldots ,\mathbf{w}_\mathbf{M}\}\) can be expressed as the product of the marginal probabilities of each single document \(D_m\), as shown in (2). J. Ment. Knowl. People confronted with negative peer pressure often find it difficult to: Say no without the fear of hurting others.

Particularly in LDA models, the generation of documents within a corpus follows the following process: A mixture of k topics, \(\theta\), is sampled from a Dirichlet prior, which is parameterized by \(\alpha\); A topic \(z_n\) is sampled from the multinomial distribution, \(p(\theta \mid \alpha )\) that is the document topic distribution which models \(p(z_{n}=i\mid \theta )\) ; Fixed the number of topics \(k=1 \ldots ,K\), the distribution of words for k topics is denoted by \(\phi\) ,which is also a multinomial distribution whose hyper-parameter \(\beta\) follows the Dirichlet distribution; Given the topic \(z_n\), a word, \(w_n\), is then sampled via the multinomial distribution \(p(w \mid z_{n};\beta )\). Distance learning solutions. Youth Serv. The latent Dirichlet allocation (LDA) model is one of the most popular topic modeling methods; it is a probabilistic model for expressing a corpus based on a three-level hierarchical Bayesian model. The 4 second rule is essentially the same technique as the 2 second rule, except 4 seconds are used due to weather / road conditions. Electronics and Mobile Communication Conference (IEMCON) 2019. https://doi.org/10.1109/IEMCON.2019.8936139 (IEEE, 2019). The Richter magnitude scale is determined by the amplitudes of the P- and S-waves at a distance of _____ km from the center of the earthquake. Both start from point A at . In the topic related to digital support, the relevance of words such as family and support remained stable, while the importance of the term difficulty decreased in the later stages of the period. So s = 0.5. Whenever an individual stops drinking, the BAL will ________________. AAAI Conf. In the subsequent months, distance learning gradually moved to integrated digital learning3, which combined remote (virtual classroom) and in-person (traditional classroom) instruction.

Do not completely stop in the middle of the road to increase distance, gradually slow down. While distance learning has generated and still generates fears and concerns, integrated digital learning has already proven itself more effective than traditional teaching. Over the last two decades, China has rapidly advanced from a middle stage to a mature stage of urbanization, and has entered a spatial development pattern dominated by metropolitan areas (CPC Central Committee and State Council, 2014).Metropolitan areas are the result of advanced urbanization, and they play an important role in national and regional economies.
