Developmental Trend of Subjective Well-Being of Weibo Users During COVID-19: Online Text Analysis Based on Machine Learning Method

Currently, the coronavirus disease 2019 (COVID-19) pandemic experienced by the international community has increased the usage frequency of borderless, highly personalized social media platforms of all age groups. Analyzing and modeling texts sent through social media online can reveal the characteristics of the psychological dynamic state and living conditions of social media users during the pandemic more extensively and comprehensively. This study selects the Sina Weibo platform, which is highly popular in China and analyzes the subjective well-being (SWB) of Weibo users during the COVID-19 pandemic in combination with the machine learning classification algorithm. The study first invokes the SWB classification model to classify the SWB level of original texts released by 1,322 Weibo active users during the COVID-19 pandemic and then combines the latent growth curve model (LGCM) and the latent growth mixture model (LGMM) to investigate the developmental trend and heterogeneity characteristics of the SWB of Weibo users after the COVID-19 outbreak. The results present a downward trend and then an upward trend of the SWB of Weibo users during the pandemic as a whole. There was a significant correlation between the initial state and the development rate of the SWB after the COVID-19 outbreak (r = 0.36, p < 0.001). LGMM results show that there were two heterogeneous classes of the SWB after the COVID-19 outbreak, and the development rate of the SWB of the two classes was significantly different. The larger class (normal growth group; n = 1,229, 93.7%) showed a slow growth, while the smaller class (high growth group; n = 93, 6.3%) showed a rapid growth. Furthermore, the slope means across the two classes were significantly different (p < 0.001). Therefore, the individuals with a higher growth rate of SWB exhibited stronger adaptability to the changes in their living environments. These results could help to formulate effective interventions on the mental health level of the public after the public health emergency outbreak.

The Evolution of Ethnic Preferential Policies in the 21st Century

Ethnic preferential policies for gaokao—the national college entrance examination—are important for students of ethnic minorities to be included in the tertiary education system in China. While these policies promote educational inclusiveness and guarantee the right to higher education for students of ethnic minority, evidence has indicated that these students are struggling to acquire equal higher education opportunities compared to their mainstream counterparts. Referring to Bourdieu's concept of cultural capital, this chapter contributes a new perspective to the existing discussion of ethnic preferential policies. The chapter examines Chinese ethnic preferential policies and relevant supporting policies in this century. It identifies the evolution of these policies, indicating the developmental trend and arguing that the inclusiveness of ethnic minority students should comprise more than adjusting the admission score. Instead, a more comprehensive approach should be taken to acknowledge and legitimise the existing cultural capital of ethnic minority students.

EXPRESS: Consonant and vowel transpositions effects during reading development: a study on Italian children and adults

Recently, Colombo, Spinelli, and Lupker (2020), using a masked transposed letter (TL) priming paradigm, investigated whether consonant/vowel (CV) status is important early in orthographic processing. In four experiments with Italian and English adults, they found equivalent TL priming effects for CC, CV, and VC transpositions. Here, we investigated that question with younger readers (age 7 to 10) and adults, as well as whether masked TL priming effects might have a phonological basis. That is, because young children are likely to use phonological recoding in reading, the question was whether they would show TL priming that is affected by CV status. In Experiment 1, target words were preceded by primes in which two letters (either CV, VC, or CC) were transposed versus substituted (SL). We found significant TL priming effects, with an increasing developmental trend, but, again, no letter type by priming interaction. In Experiment 2 the transpositions/substitutions involved only pairs of vowels with those vowels having either diphthong or hiatus status. The difference between these vowel clusters is only phonological, thus the question was would TL priming interact with this factor. TL priming was again found with an increasing trend with age, but there was no vowel cluster by priming interaction. There was, however, an overall vowel cluster effect (slower responding to words with hiatuses) which decreased with age. The results suggest that TL priming only taps the orthographic level, and that CV status only becomes important at a later phonological level.

Review: Radionuclide Molecular Imaging Targeting HER2 in Breast Cancer with a Focus on Molecular Probes into Clinical Trials and Small Peptides

As the most frequently occurring cancer worldwide, breast cancer (BC) is the leading cause of cancer-related death in women. The overexpression of HER2 (human epidermal growth factor receptor 2) is found in about 15% of BC patients, and it is often associated with a poor prognosis due to the effect on cell proliferation, migration, invasion, and survival. As a result of the heterogeneity of BC, molecular imaging with HER2 probes can non-invasively, in real time, and quantitatively reflect the expression status of HER2 in tumors. This will provide a new approach for patients to choose treatment options and monitor treatment response. Furthermore, radionuclide molecular imaging has the potential of repetitive measurements, and it can help solve the problem of heterogeneous expression and conversion of HER2 status during disease progression or treatment. Different imaging probes of targeting proteins, such as monoclonal antibodies, antibody fragments, nanobodies, and affibodies, are currently in preclinical and clinical development. Moreover, in recent years, HER2-specific peptides have been widely developed for molecular imaging techniques for HER2-positive cancers. This article summarized different types of molecular probes targeting HER2 used in current clinical applications and the developmental trend of some HER2-specific peptides.

Institutional and regional features of organized second home development in Russia

The article studies the features of second home land development in Russia. Basing on the data of the All-Russian agricultural censuses, the author shows that organized second home development is represented by two quantitatively and qualitatively different processes, namely: development of residential dachas, observed in horticultural non-profit partnerships (HNP) with dominant residential, recreational and agricultural functions, and development of agricultural dachas (vegetable gardens), observed in gardening non-profit partnerships (GNP), performing only an agricultural function. Despite regional differentiation, the general developmental trend might be described as gradual strengthening of the recreational and residential functions of the HNPs, which is facilitated by institutional regulation. The absolute and relative scales of the GNPs extension are gradually decreasing, but due to the unique localization and long-term traditions of subsidiary gardening, they remain relevant, especially during periods of crisis. Therefore, in some regions, their share in the total land of garden and dacha formations substantially exceeds the national average. The desire of the owners to supplement the functions of the GNPs with a permit for the construction of houses leads to the transfer of gardening lands to other categories, but in the absence of such an opportunity, Russian GNPs remain an analogue of foreign «allotment gardens», where one cannot spend the night, but can do gardening.

Comparison of the Development of TikTok and Bilibili

According to the comparison between TikTok and Bilibili in five aspects, TikTok is far more than Bilibili in terms of user flow and business model. However, TikTok still has some disadvantages, such as the failure to provide high-quality short videos or the lack of development prospects for creators. TikTok and Bilibili are two related but different video platforms. Through the comparison between them, we can intuitively understand the problems faced by the two companies and predict the developmental trend of the two in the future. People can clearly understand the development and future trend of entertainment video platforms through the comparison between the two. The author thinks, TikTok will continue to generate high revenue with high traffic, and if Bilibili continues to produce high-quality videos and tries to break into the market, it will be able to gain a foothold like Youtube.

Using Visual Representations to Demonstrate Complexity in Mixed Emotional Development Across Childhood

Previous studies have shown a developmental trend in mixed emotional understanding. As children develop throughout childhood, they begin to recognise simultaneity of positive and negative emotions. However, previous studies have limited ecological validity as they assessed emotion choice using only a single positive and single negative emotion. Therefore, the present study aims to broaden the understanding of mixed emotional development by allowing a wider emotion choice. Mixed emotions were measured using the analogue emotions scale (AES) which allows both intensity of the emotional responses and time to be captured. In the present study, 211 children aged 4–10 were divided into one of three protagonist conditions (self, peer and adult) and read a vignette about the protagonist moving house. Choosing from seven emotions (happy, calm, surprise, sad, worry, fear and anger), they plotted the intensity and duration of each emotion they thought was represented in the vignette. The present study replicated the developmental trend that younger children are more likely than older children to choose a single emotion, and older children are more likely to perceive more simultaneity of emotion than younger children. This trend was demonstrated in the number of emotions chosen, and also the complexity of the AES pattern plotted. Additionally, the present study extended previous research by demonstrating that by broadening the emotion choice, the emotion interaction is more complex than previous studies were able to show.

TYPES OF AGGRESSIVE BEHAVIOR AMONG LEARNERS WITH MODERATE INTELLECTUAL DISABILITY IN NIGERIA AS PERCEIVED BY TEACHERS

This study examined aggressive behavior (verbal aggression, physical assault, socially unacceptable and destructive behavior) among learners with moderate intellectual disability in south-western Nigeria, through teachers’ perceptions. The study used a descriptive survey design. Convenient sampling technique was used to select respondents (87 teachers of pupils with intellectual ability in private and public schools in south West Nigeria). The aggressive behavior scale (ABS) was used to elicit responses. Data retrieved was analysed using descriptive and inferential statistics. Results showed that teachers’ perception of the developmental trend of aggressive behavior among learners with moderate intellectual disability was significant (T = 44.385, Mean Difference = 3.115 while p < .05). Also, there was no significant gender difference in verbal aggressive (F=0.997, p>.05), physical aggressive (F=3.628, p>.05), socially unacceptable aggressive (F=1.233, p>.05), and destructive behavior (F=0.571, p>.05). Interventions should be in line with these.

PROPOSED COPING SUGGESTIONS AND STRATEGIES TO SOLVE THE TRUST DEFICIT FOR THE INDIANS AND CHINESE MEDIA IN THE POSTCOVID-19 ERA

The rise of India and China is a major historical developmental trend that has led to peaceful India-China media cooperation. From a long-term strategic point of view, the Indian and Chinese media platforms should seek common ground while overcoming differences and increasing mutual trust. The governments of India and China should grasp the dominant power of public opinion in traditional media, new media and self-media platforms. We must increase the number of each other's reporting stations and media branches to promote the "opposite column" in the content of the mainstream media. Meanwhile both sides should strengthen the training of reporters and journalist, thus improve the existing India-China media cooperation systems and gradually cut mutual misunderstandings by building friendly provinces, sister cities, and cultural and tourism exchange projects to jointly serve the two countries' national strategy for the smooth realization of a peaceful rise.

The Development of the Rank-Order Stability of the Big Five Across the Life Span

Several studies have suggested that the rank-order stability of personality increases until midlife and declines later in old age. However, this inverted U-shaped pattern has not consistently emerged in previous research; in particular, a recent investigation implementing several methodological advances failed to support it. To resolve the matter, we analyzed data from two representative panel studies and investigated how certain methodological decisions affect conclusions regarding the age trajectories of stability. The data came from Australia (N = 15,465; Study 1) and Germany (N = 21,777; Study 2), and each study included four waves of personality assessment. We investigated the life span development of the rank-order stability of the Big Five for 4-, 8-, and 12-year intervals. Whereas Study 1 provided strong evidence for an inverted U-shape with rank-order stability declining past age 50, Study 2 provided more mixed results that nonetheless generally supported the inverted U-shape. This developmental trend held for single personality traits as well as for the overall pattern across traits; and it held for all three retest intervals—both descriptively and in formal tests. Additionally, we found evidence that health-related changes accounted for the decline in rank-order stability in older age. This suggests that if analyses are implicitly conditioned on health (e.g., by excluding participants with missing data on later waves), the decline in stability in old age will be underestimated or even missed. Our results provide further evidence for the inverted U-shaped age pattern in personality stability development but also extend knowledge about the underlying processes.
