Impact of COVID-19 restrictions on the research environment and motivation of researchers in Japan

The environment surrounding researchers has changed significantly in the face of COVID-19 restrictions. An online self-reported questionnaire was completed by 10,557 participants between June 15 and 19, 2020. The impact on work/research activities and harassments under COVID-19 conditions was higher among researchers (1963) compared to non-researchers (8572). We further examined the effect of COVID-19 restrictions on 300 researchers. Women were significantly more likely to report being harassed than males. The overall “decrease in research motivation” was higher in women. The restrictions on research activities because of COVID-19 restrictions caused future anxiety and a decrease in research motivation.


Introduction
The novel coronavirus disease (COVID-19)-which emerged in Wuhan, China, in November 2019-has grown into a global threat and was eventually declared a global pandemic [1]. It has seriously impacted the lives of many and caused numerous deaths. On April 7, 2020, the Japanese Head of the Novel Coronavirus Response Headquarters declared a state of emergency for seven regions including Tokyo [2]; by April 16, the state of emergency expanded across the country [3]. The Japanese government had asked for people to reduce their contact with one another by at least 70% and ideally 80% [2]; business operations and schools were also requested to be temporarily ceased [4]. Entertainment events and meetings were suspended or postponed; the 2020 Summer Olympic Games (scheduled to be held in Tokyo) were no exception [5]. During this period, staying at home and to avoiding unnecessary outings were advisable; several companies also adopted remote and working-from-home strategies. Several industries-such as accommodations, food and beverage services, travel, and amusement services-have suffered significant financial losses because of the suspension of "non-essential" services during the state of emergency to prevent the transmission of the disease [6,7].
For combating COVID-19, Japan implemented social distancing as one of the models; it comprised the "3 Cs" signifying awareness of the following: 1. Closed spaces with insufficient ventilation, 2. Crowded situations, and 3. Conversations held at a short distance [2,4]. In educational settings such as schools, face-to-face lectures are banned as part of the 3 Cs; as a result of these measures, online lectures and classes in Japan are expected to improve [8,9]. Although lockdown and selfrestraint (as caused by  have induced functional changes in the style of attending class (described above), it is feared that this may have a negative effect on the mental health of the students by restricting their activities both outside and on campus [10][11][12]. A survey of 66 Chinese college students found that the act of recognizing the threat posed by COVID-19 could lead to negative emotions as a result of poor sleep quality [10]. In a survey of 1000 Greek university students, many participants complained of anxiety and depression because of the COVID-19 quarantine [11]. Moreover, because of the COVID-19 quarantine, there was a 2.5-to 3.0-fold increase in depression, and an almost 8.0fold increase in suicidal ideation, when compared to the prevalence in the general population [11]. These findings highlight the importance of supporting the mental health of students and to reconsider students' Progress in Disaster Science 8 (2020) 100128 school life activities during the current measures against COVID-19, and to further prepare against the next wave.
The fight against COVID-19 has also affected research activities at universities and institutes, with many scientists having had to stop or limit their research during the pandemic [13]. Research using experimental equipment and reagents so-called wet-lab experimentation cannot be replicated in remote working conditions. Even if scientists can conduct experiments in a laboratory, the threat of the "3 Cs" occurring in the laboratory may increase the risk of novel coronavirus infection. Researchers around the world (including Japan) are always in competition because of the results-based system in which they operate [14] as such, delays in research (because of the restrictive countermeasures applied by governments in battling COVID-19) may lead to greater emotional strain on scientists, manifesting as anxiety and frustration. However, the truth on the matter remains unknown, as there is no survey report focusing on the issue. For a definitive picture, it is necessary to compare the situation before and after the COVID-19 pandemic, but COVID-19 continues to spread without any sign of an end. Therefore, the purpose of this study was to clarify the impact of COVID-19 measures on the research environment and motivation of Japanese scientists during the current pandemic.

Materials and methods
The questionnaire survey was outsourced to Cross Marketing Inc. (Tokyo, Japan). Survey targets were extracted from members registered in a monitor member database of Cross Marketing, and the questionnaire survey was conducted by accessing the survey web site of Cross Marketing. For this study, the questionnaire was completed by approximately 10,000 people; in total, we obtained responses from 300 researchers from the 10,000 initial respondents. The survey was conducted for five daysfrom Monday, June 15, to Friday, June 19, 2020. The questionnaires were filled out anonymously. Documents for obtaining the participants' consent are shown in the Supplementary document. The Ethics Committee of the International Research Institute of Disaster Science, Tohoku University, approved the research protocol of this survey (No. 2020-006). Microsoft Excel (Microsoft Corporation, Redmond, WA, USA) was used to collect and manage the data obtained. Cross Finder 2 (Cross Marketing, Tokyo, Japan) was used for cross-tabulation. A chi-squared test via StatView ver. 5.0 (SAS Institute Inc., USA) was used for comparison between the groups.

Results
The questionnaire was collected from 10,557 participants. The questions, along with the number of responses from these participants, are summarized in Fig. 1. The number of people who reported that their work has been negatively affected by measures in combating COVID-19 is 4479 (45.3%) (Fig. 1D). Further, 1325 (12.6%) of respondents felt (at the time of answering) that they had received harassment, while 287 (2.7%) felt that they had been responsible for harassing someone (Fig. 1E). Among the 10,557 respondents, 1963 people replied "Yes" to the question "Do you do 'research'?"; 8572 replied with a "No," while 22 answered "Other" (Fig. 1F). In this study, the person who answered "Yes" is defined as a researcher and is further compared to the person who answered "No," the non-researcher group. Table 1 summarizes the factors with significant differences in this comparison. The number of females in the researcher group was relatively low when compared to the non-researcher group ( Table 1). The number of researchers who had their research or working activities affected by COVID-19 countermeasures was higher than that of non-researchers (Table 1). Regarding harassment, the ratio of both those who received it and those who gave it was high among the researchers' group (Table 1). The study also conducted a further detailed survey of 300 of the 1963 researchers. The questions to participants and the number of responses are summarized in Fig. 2. Tables 2 to 7 show the comparisons between groups in which significant differences were recognized. Various comparisons were made with questions other than those provided in Tables 1 and Tables 2 to 7, but no significant relationship was found in any of them. expressing that they "Strongly felt" that they had been harassed, in comparison to male respondents ( Table 2). Although many women reported that their motivation was (at the time of questioning) "Slightly decreased," male researchers reported a higher rate of feeling that their motivation was "Significantly decreased" ( Table 2). Table 3 summarizes the factors in which significant differences were observed in response to the following question: "How much of an impact (or damage) did the combating of COVID-19 have on (or cause to) your research/ work environment?" In the group who had their research environment impacted by COVID-19 measures, a high percentage of respondents reported having been harassed and that there was a presence of a negative atmosphere within their laboratories (Table 3). Conversely, in the groups that were seriously affected by COVID-19 measures, the proportion of those who felt a positive atmosphere in their laboratories is low ( Table 3). The group affected by COVID-19 measures reported high rates of anxiety over their future research activities and a decrease in motivation to conduct research (Table 3). Table 4 summarizes the factors to which significant differences are observed in response to the following question: "Have you ever felt that you were the victim, or perpetrator, of some kind of harassment in the face of a new coronavirus infection?" Among the groups that felt harassed in the face of COVID-19 measures, a high proportion reported feeling a negative atmosphere, anxiety, and decreased motivation for their research (Table 4a). There were only four researchers who felt they perpetrated harassment in the face of COVID-19 measures. All these researchers felt a negative atmosphere in the laboratory. In contrast, regarding their motivation for research, none of them were "Significantly decreased," and all were "Slightly decreased" (Table 4b). The factor associated with the research area is shown in Table 5. The proportion of researchers who felt that they had received harassment was higher than the other areas in the life sciences-related faculty ( Table 5). Table 6 summarizes the factors with significant observed differences to the following questions: "Was there a negative atmosphere, exemplified by questions such as 'Should we continue research in this situation?'" (Table 6a) and "There was a positive atmosphere, exemplified by statements such as 'We should continue research precisely because we are in such a situation'" (Table 6b). The Negative Feeling Group and the Positive Feeling Group exhibited an opposite relationship (Table 6a). The Negative Feeling Group felt that, under COVID-19 measures, their research activities were reduced, along with the quality thereof (Table 6a). The Negative Feeling Group further reported a high rate of anxiety concerning their future research activities, as well as a decrease in motivation to conduct research (Table 6a). The Positive Feeling Group, however, was more likely to choose to increase the quantity and quality of the research they conducted, as well as reporting an increase in their motivation (Table 6b). The group that often-felt the presence of a positive atmosphere also has a higher ratio of respondents who did not feel any anxiety concerning their future research activity particularly when compared to other groups, including the group that sometimes-felt the presence of a positive atmosphere (Table 6b). Table 7 summarizes the factors with observable and significant differences to the following question: "Has your research activity, in regard to the quantity (Table 7a) quality (Table 7b) thereof, changed under the measures for the combating of COVID-19?" Under the COVID-19 measures, the group who felt a decrease in research amount or quality had a higher rate of anxiety concerning their future research activities (Table 7a,b). The group who felt a decrease in their research amount or quality also had a high rate of decreased research motivation, while the group who felt an increase in the research amount and quality had a high ratio of increased motivation (Table 7a,b). There is a positive relationship between changes in research amount and quality (Table 7a).
In the free description regarding the harassment present under COVID-19 conditions, some academic harassment was pointed out. Among the 300 researchers, 169 were free to comment; of these, 122 were considered to be meaningful. There were cases in which respondents were blamed for their unfamiliarity with teleworking or remote lectures (10 cases, 8.2%). There were also some cases in which employees were forced to work on-site, even if remote work was possible; some were forced to work or conduct research in a situation strictly warned against by the "3 Cs" of social distancing (7 cases, 5.7%). Some researchers found that the restrictions on research and travel (for attending academic conferences) were harassment, even though these restrictions were known to be measures against the spread of infection (7 cases, 5.7%). Conversely, many researchers who did not feel they were being harassed cite that contact with the harassers has been reduced or eliminated because of being able to work from home (13 cases, 10.7%). Some respondents were comfortable with remote work, employment at their discretion, and the lack of direct supervision under the measures for combating COVID-19 (6 cases, 4.9%). In the free description concerning anxiety about their future research, among the 300 researchers, 183 were free to comment; of them, 179 were considered to be meaningful. Many researchers expressed concern over how long their research activities may be restricted (23 cases, 12.8%). These researchers were worried about reducing their own research activities, the reduction in research funds (including both competitive grants and school public funds) (30 cases, 16.8%), and increased difficulty in securing posts (17 cases, 9.5%). Researchers conducting field work and face-to-face research were also worried that they would not be able to conduct their research (11 cases, 6.1%). In terms of research which makes use of library materials and on-campus databases, activity was significantly affected by working from home due to the campus lockdown (12 cases, 6.7%). Researchers further expressed their concern that communication among researchers would be reduced due to the restrictions in business trips abroad and participation in academic conferences (32 cases, 17.9%). Some researchers in charge of classes were apprehensive about their own research time being lost because of the time spent dealing with the new remote and on-demand lecture styles (15 cases, 8.4%). The status of participants and research fields are also biased, and the number of participants was small for subgroup analysis. Therefore, it was difficult to statistically evaluate the respondents' comments in this survey.

Discussion
In this study, we focused on the impact of the influence of the ongoing COVID-19 pandemic on researchers. We obtained important information to understand the current situation of researchers in Japan under COVID-19 measures. However, to clarify their effects, the situation of three phases (i.e. before, during, and after the COVID-19 pandemic) must be compared.
In addition, future studies should investigate the "quality," "quantity," and "harassment" of research more concretely and quantitatively. This study reveals that researchers are more likely to be involved in harassment (either as recipients or perpetrators) than other populations during the period of restrictions in combating COVID-19 (Table 1). Some researchers reported being forced to work in the lab, despite governmentled encouragement to work from home to avoid the risk of infection. In contrast, in the comments to the free description, it was noted that because of the nature of remote work, some researchers had less contact with harassers and had a relatively more comfortable time.
Laboratories in academia are characterized by "strong hierarchies" [15,16] and "small, globally-interconnected specialized communities," which may lead to various types of harassment [16]. Since the occupations of other populations have not been clarified in this study, it is necessary to further examine these occupational areas. Furthermore, across the 300 researchers surveyed, the ratio of those who received harassment was higher among the field of life science research (26.0%) than other academic fields (9.7-16.6%) ( Table 5). It was further reported in a previous study that medical-related science departments were less recognize that "Harassment in organization" and "pressuring to fabricate, falsify, or plagiarize research outputs" were academic harassment than other departments surveyed in Japanese private university [16]. This finding is suggested to be a result of the differences in the organizational structure wherein faculty members of humanities departments in Japan tend to conduct research and education independently; in the medical science lab, several staff members are engaged in both research and medical care [17]. It has been suggested that the concept of pandemics may move to an interdisciplinary science with an integrated approach of life sciences, information technology, artificial intelligence, meteorology, ecology and so on [18]. Further studies are awaited about the differences of each research field. Various types of harassment, typified by sexual harassment, are wellrecognized to affect more women than men [19][20][21][22]. It has been previously reported (via a survey of Japanese private university staff) that women have a higher prevalence of experiencing all forms of harassment-sexual, gender-related, and academic-than men [18]. There is a causal relationship between the existence of academic harassment and impaired academic motivation [23]. It has been pointed out that decreased academic motivation can potentially lead to poor academic performance and the reason for drop-out [23]. Several studies have raised concerns about the occurrence of discrimination against women during COVID-19 countermeasures [24][25][26]. However, for women's harassment, it was necessary to compare during COVID-19 with peacetime. In this survey, women (24.1%) are observed to be more likely to be harassed and less motivated during the COVID-19 restrictions than men (11.4%) ( Table 2). The free descriptive answer texts in this survey did not, at least, include a direct description of sexual harassment. Further verification, including detailed deciphering of free descriptions, is necessary to determine whether this finding was unique to the situation faced by researchers under COVID-19 countermeasures.
In this survey, 41 out of 300 (13.7%) researchers responded that they were harassed, but only four (1.3%) felt they had perpetrated harassment (Table 4). It is considered, thus, that this finding is because of the low levels of awareness had by perpetrators of harassment on their actions [27]. In contrast, it is very interesting that these four perpetrators also all felt the presence of a negative atmosphere in the lab environment, as well as reporting that their motivation had decreased (Table 4). It is necessary to devise a wet-lab that avoids the "3C"-s by strict online schedule management and enhance online communication between researchers. It is important to hold online lab meetings on a regular basis, and it is the responsibility of the principal investigator and lab manager to listen not only to the research progress of junior researchers or students but also to their mental state. Regarding harassment countermeasures, it is necessary to conduct continuous investigations and activities by the harassment countermeasures committee and the consultation desk even during the COVID-19 pandemic [24]. We believe that the problems and anxieties that  In this study, we divided laboratory situations into two distinct atmospheres: "negative atmosphere: Should we continue to conduct research in this situation?" and "positive atmosphere: We should continue to conduct research precisely because we are in such a situation." The researchers whose research progress was affected by COVID-19 recognized a negative atmosphere within their labs and were worried about their own future research activity (Table 3). It is suggested that those feelings described above might have led to a decrease in research motivation. The rate of the decreased motivation of those who had an effect (was lower than that of those who had no effect on research activities (Serious impact, 39.2%; Some impact, 26.7%; Nothing, 8.1%) ( Table 3). The lab's negative atmosphere was associated with negative factors such as reduced research volume and quality, anxiety, and reduced motivation (Table 6a). The lab's positive atmosphere resulted in the opposite of that identified in negative atmospheres (Table 6b). It is considered important to maintain a positive atmosphere in a lab setting, even in the face of a disaster. Among the group that experienced a positive atmosphere, only 1.7% (1/60) of respondents did not sympathize with the atmosphere (Fig. 2L). Conversely, in the  Have you ever felt that you were the victim, or perpetrator, of some kind of harassment in the face of a new coronavirus infection? P values were calculated by chi-square test.

It was also pointed out that communication with researchers from inside and outside the country via the society of academics was reduced. Utilizing online communication methods during normal times will further help prevent researchers from being isolated during a disaster. Changes in the quantity and quality of the research conducted during the COVID-19 restrictions were positively associated with changes in motivation and anxiety ( Table 7). The quality and amount of research are considered to be important indicators for researchers to be evaluated. However, it is necessary to investigate the contents more concretely to formulate future measures. In addition, although "very anxious" is thought to lead to "Significantly decreased motivation," the relationship between them could not be clarified in this study. Many Japanese researchers are funded by the governmentsuch as KAKENHI (The Ministry of Education, Culture, Sports, Science and Technology or Japan Society for the Promotion of Science) [28]. In addition, public disclosure of research results such as "scholarly papers," "presentations at conferences," and "writing of books" is adopted as an evaluation item for academic staff at most universities or institutes [29]. Researchers are worried that research results will be required as usual, despite the delays in their research (because of work restrictions faced while society combats COVID-19). Some researchers are further worried that these issues may affect the acquisition, and maintenance, of academic positions in the future as such, it is hoped that the policy for researchers working through the COVID-19 crisis will be promptly decided upon. In addition, it has been reported that Japanese university teachers are exhausted from adapting to the new style of taking classes class [30]. In this survey, researchers displayed fear concerning the time that would be needed to be spent on preparing for the new on-demand or remote lecture patterns. It is known that researchers who are obliged to both teach and conduct research have lower levels of well-being related to demands and control than those who are obliged to do either one or the other [16]. One of the researchers' concerns was that library materials and databases were no longer available because of campus lockdowns. As such, it is expected that the development of online facilities at Japanese universities will be promoted multilaterally in response to taking social measures against COVID-19 [8,9].
One study reported that many students cannot imagine an academic career because research at the university level is highly competitive, keeping a balance with family life appears difficult, and wages are low [31]. A survey of over 6000 graduate students revealed that they were anxious [32]. While most of the respondents were satisfied with pursuing a Ph.D., more than one-third needed help with anxiety and depression caused by their Ph.D. research [32]. Therefore, students and young scientists are considered to already be worried about their research activity regardless of the "Has your research activity, in regard to the quantity and quality thereof, changed under the measures for the combating of COVID-19". P values were calculated by chi-square test.
presence of a disaster (such as . These feelings of anxiety may be heightened and resurface by greater instability within the research environment in the face of disasters. Nature Research surveyed the activities of research leaders or mentors in 2019. 1 The demand for support measures for "securing research time" and "reducing clerical work" was remarkable. Due to the huge amounts of miscellaneous affairs and clerical work, research and paper writing time which should be the center of original work activities is being cut off. In this survey, which had a relatively high ratio of professors (39.0%) and associate professors (31.7%) (Fig. 2H), it was not possible to clarify the characteristics of each position. It will be necessary to clarify the differences between positions for example: "professors and students," and "senior and junior researchers" to prepare for the lab procedure for conducting research in the event of a disaster. Enhancing communication between researchers through webinars and online conferences, as well as casual participation will sustain researchers' motivation [33,34]. In gene expression research, open databases can be used to verify the data obtained previously and identify new research targets. When researchers are unable to do research, they will be able to spend time working online with lab members to plan future projects [34]. From this pandemic experience, it is necessary to build sustainable research, that is, a new normal research environment.

Conclusion
The impact of disasters (and the response to them) on researchers' motivation has not been clarified. Researchers, especially young ones, are always experiencing instability in their careers. They are exposed to a variety of unique concerns that are different from non-researchers, such as obtaining research funding, pressure on the demand for research results, and securing a position. There is concern that the anxiety caused by these excessively competitive environments will erupt because of the suppression of activities by COVID-19. Therefore, it is important to have an online community in peacetime to keep researchers from being isolated. Moreover, the government should understand the psychology of researchers when research activities are hindered, and respond through measures against COVID-19. In addition, lab leaders such as professors and principal investigators will need to plan lab operations in case of disaster. To clarify the psychology of researchers concerning disasters, further comparative studies between disasters and normal situations are required.
