A comprehensive analysis of evolution and underlying connections of water research themes in the 21st century.

This work aimed to reflect the advancements in water-related science, technology, and policy and shed light on future research opportunities related to water through a systematic overview of Water Research articles published in the first 21.5 years of the 21st century. Specific bibliometric analyses were performed to i) reveal the temporal and spatial trends of water-related research themes and ii) identify the underlying connections between research topics. The results showed that while top topics including wastewater (treatment), drinking water, adsorption, model, biofilm, and bioremediation remained constantly researched, there were clear shifts in topics over the years, leading to the identification of trending-up and emerging research topics. Compared to the first decade of the 21st century, the second decade not only experienced significant uptrends of disinfection by-products, anaerobic digestion, membrane bioreactor, advanced oxidation processes, and pharmaceuticals but also witnessed the emerging popularity of PFAS, anammox, micropollutants, emerging contaminants, desalination, waste activated sludge, microbial community, forward osmosis, antibiotic resistance genes, resource recovery, and transformation products. On top of the temporal evolution, distinct spatial evolution existed in water-related research topics. Microplastics and Covid-19 causing global concerns were hot topics detected, while metagenomics and machine learning were two technical approaches emerging in recent years. These consistently popular, trending-up and emerging research topics would most likely attract continuous/increasing research input and therefore constitute a major part of the prospective water-related research publications.

Data on media use and mental health during the outbreak of COVID-19 in China.

The Coronavirus disease (COVID-19) spread rapidly in China in beginning of 2020. Self-quarantine was suggested by Chinese government to block the spread of the COVID-19. During the self-quarantine, the media played an indispensable role in acquisition of information about the disease. And it could also impact on people's mental health. Therefore, it is necessary to study the psychological outcome resulted from media use during the outbreak of COVID-19. The data in this article could help researchers to explore the mechanism between media use and mental health, and to have a deeper comprehension of the impact of media use on mental health during a public health emergency. The dataset provided in this article included 917 participants recruited from different provinces all over China. Among the participants, there were 304 males and 613 females, with an average age of 28.6 and a standard deviation of 9.5. They took Media Use Questionnaire (MUQ), Empathy-Sympathy Questionnaire (ESQ), Positive and Negative Affect Scale (PANAS), Death Anxiety Questionnaire (DAQ), Meaning in Life Questionnaire (MLQ), State boredom Questionnaire (SBQ), and Depression Anxiety Stress Scale-21 (DASS-21) to assess their media use and mental health during the outbreak of COVID-19. All these instruments for data collection were Chinese versions. In addition, a .csv file consists of major variables we used are included as a supplementary material. Descriptive statistics and hierarchical regression had been conducted with these data. For a discussion of the findings based on the dataset please see the article: Media use and acute psychological outcomes during COVID-19 outbreak in China [1] and Psychological distress and state boredom during the COVID-19 outbreak in China: the role of meaning in life and media use [2].

The Relationship Between Media Involvement and Death Anxiety of Self-Quarantined People in the COVID-19 Outbreak in China: The Mediating Roles of Empathy and Sympathy.

The COVID-19 outbreak put health threat to people globally, and self-quarantine was suggested by the Chinese government to contain the outbreak. In self-quarantine, media was the most important way to get information about the outbreak. However, the relationship between media involvement and death anxiety, and the underlying mechanism are poorly understood. We conducted an online survey of 917 participants to assess the media involvement and other potential factors (empathy, sympathy and affect) which might affect death anxiety. Correlation analysis and mediation models were conducted to examine the relationship between media involvement and death anxiety, and the possible mediating roles of empathy, sympathy, and affect. It was found that media involvement was positively associated with death anxiety. Empathy, sympathy, and negative affect played mediating roles between them. However, empathy and sympathy act differently in the association, as empathy could lead to the increase of negative affect, while sympathy did not.

Psychological distress and state boredom during the COVID-19 outbreak in China: the role of meaning in life and media use.

BACKGROUND: Epidemics are associated with increased burden of psychological distress. However, the role of boredom on mental health during epidemic periods has seldom been explored. OBJECTIVE: This study attempted to examine the effect of state boredom on psychological outcomes, and the role of media use and meaning in life among the indirectly exposed Chinese adults in the initial phase of the COVID-19 outbreak. METHOD: An online survey was administered to 917 Chinese adults on 28 January 2020 (1 week after the official declaration of person-to-person transmission of the coronavirus). Self-report questionnaires were used to assess state boredom, anxiety, depression, stress, media use and meaning in life. Moderated mediation analysis was conducted. RESULTS: Our results indicated that the effect of state boredom on anxiety and stress, but not depression, were mediated by media use and that sense of meaning in life modified this association. Meaning in life served as a risk factor, rather than a protective factor for the negative psychological outcomes when people experienced boredom. The association between boredom and media use was significant for high but not low meaning in life individuals. CONCLUSION: These findings demonstrated that boredom and media use were associated with an increased burden or psychological distress in the sample. It is important to pay attention to the possible negative impact of boredom and media use during COVID-19, and find more ways to cope with boredom, especially those with high presence of meaning in life.

Antecedentes: Las epidemias están asociadas con aumento de la carga de malestar psicológico. Sin embargo, el papel del aburrimiento en la salud mental durante periodos de epidemia ha sido rara vez explorado.Objetivo: Este estudio intentó examinar el efecto del estado de aburrimiento en las consecuencias psicológicas y el papel del uso de los medios y significado en la vida entre los adultos chinos indirectamente expuestos en la fase inicial del brote de COVID-19.Método: Se administró una encuesta online a 917 adultos chinos el 28 de Enero del 2020 (una semana después de la declaración oficial de la transmisión del coronavirus persona a persona). Se usaron cuestionarios de auto-reporte para evaluar el estado de aburrimiento, ansiedad, depresión, estrés, uso de medios y significado en la vida. Se realizó un análisis de mediación moderado.Resultados: Nuestros resultados indicaron que el efecto del estado de aburrimiento sobre la ansiedad y el estrés, pero no depresión, estuvieron mediados por el uso de los medios y que el sentido de significado en la vida modificó esta asociación. El significado en la vida sirvió como factor de riesgo, más que como un factor protector para las consecuencias psicológicas negativas cuando la gente experimentó aburrimiento. La asociación entre aburrimiento y uso de los medios fue significativa para el significado alto pero no bajo en la vida en los individuos.Conclusiones: Estos hallazgos demostraron que, en la muestra, el aburrimiento y el uso de los medios estuvieron asociados con un aumento de la carga o malestar psicológico. Es importante poner atención acerca del posible impacto negativo del aburrimiento y el uso de los medios durante el COVID-19, y encontrar más formas de lidiar con el aburrimiento, especialmente aquellos con presencia alta de significado en la vida.
