This study aimed to examine (1) whether confidence in political and health authorities predicted intention to adopt recommended health-protective behaviours and (2) whether age, gender and education level moderated the relationship between confidence in political and health authorities and health protective-behaviours (download the COVIDSafe app, wear a face mask and stay at home).

This study assessed 1,206 Australians using an online survey. Participants answered questions regarding their confidence in political and health authorities and intention to adopt health-protective measures.

Confidence in health and political authorities predicted intention to stay home and intention to download the COVIDSafe app, but not to wear a face mask in public spaces. Age moderated the relationship between confidence in authorities and intention to stay home (i.e. among respondents with less than 54 years old, confidence in authorities was associated with higher intention to stay home). Further, age and education level moderated the relationship between confidence in authorities and intention to download the COVIDSafe app (i.e. among older respondents and those with a university degree or higher, confidence in authorities was more strongly associated with higher intention to download the COVIDSafe app). The interaction between confidence and education predicted adoption of mask-wearing (i.e. among participants with a university degree or higher, more confidence in authorities was associated with higher intention to wear a mask in public spaces).

Our findings can inform the development of targeted communications to increase health-protective behaviours at early stages of future pandemics.

The purpose of this paper is to provide empirical evidence of a causal nature about the relationship between wages and churning (“excessive” worker turnover).

Matched employer‐employee panel data from Portugal, covering the period 1986‐2000 are used in the study. Econometric methods are also used, including random effects tobit models, fixed effects and instrumental variables.

Unlike in previous research (which typically does not consider causal relationships), the paper presents evidence that wages do not necessarily decrease the amount of churning. If employers are forced to increase pay, they may respond by hiring different workers. Detailed evidence about the nature of job and worker flows and churning levels across industries is presented.

Future research should examine the paths of workers whose wages are affected by collective bargaining.

The paper provides additional evidence that effort may not be particularly sensitive to wages in some industries/occupations. The should be a better understanding of role of wages in personnel policies.

This paper is probably the first that seeks to examine the causal relationship between wages and churning. The results will be of interest to labour economists and human resource management experts.

Studies wage dispersion across firms and time in a specific industry that exhibits competitive features – the Portuguese clothing industry in the 1991‐1994 period. By drawing on a large matched employer‐employee panel, obtains the following results: the workers' firm affiliation plays an important role in wage determination; there is a sizeable and persistent dispersion of firm‐fixed effects, which is also similar for workers of different tenure levels and occupations; workers in high‐turnover firms are generally paid less. It is believed that these findings are not consistent with a simple competitive labour market model.

With an ever-expanding focus on reading and mathematics, many elementary schools have chosen to reduce time previously reserved for social studies. Elementary teachers who understand both the relevance of social studies content and the effectiveness of interdisciplinary teaching regularly incorporate applicable history-based children’s tradebooks in their curricula. Locating developmentally appropriate books is simple. Teaching history using children’s literature can be effective. It can be counterproductive, however, if the selected book is replete with historical misrepresentations. Teaching historical thinking in elementary school is problematic no matter what the teaching tool, and there are few methodological roadmaps for elementary teachers. Here, I first suggest ways for teachers to nurture elementary students’ historical thinking using anecdotes from everyday activities and literature with themes germane to history and multiculturalism. Then, I suggest ways for elementary educators to locate and develop engaging, age-appropriate, and historically accurate curricular supplements. Using literature on Christopher Columbus as a reference point to facilitate young students’ historical thinking, I propose an interdisciplinary approach, discipline-specific historical literacy strategies, and history-themed authentic assessments.

The aim of this paper is to analyze relationships of cooperation and conflict between a mining company and the involved communities, focusing on the presence of the mining company (MSX) in Cerro de San Pedro, Mexico.

The paper focuses on the co‐operation and conflict between firms, communities, new social movements and the role of government.

The presence of the mining company has caused a severe social conflict among the inhabitants of San Pedro, Soledad y San Luis, alerting all who are concerned with historic heritage, cultural and environmental issues. At the center of the controversy is the cheap and efficient technology. Federal and state laws were violated. It is quite evident that there was a lack of sensitivity of foreign mining companies toward the consequences of their activities upon the communities and environment. This case also shows the lack of negotiation between firms, communities, new social movements and governments. Information about externalities and future costs of company activities is crucial but more crucial is formulation and implementation of more sensitive policies to avoid damage to the environment, biodiversity and health of the population. Governmental institutions must be aware that their decisions may affect the quality of life of present and future generations for the sake of a small increment in economic growth and large increase in private benefits of a small group of investors. More informed citizens tend to be more active protestors, such as the case of the students in San Luis. Contact between informed individuals of diverse groups and organizations helps to exchange experiences and create public opinion in favor of mobilization. Community participation and involvement in decision‐making of community development planning is quite limited by the lack of critical information. This fact is critical when the local government cannot provide the right information because there are other interests affecting the process.

The paper highlights the lack of sensitivity of foreign mining companies towards local communities.

The purpose of this study is to identify the relationship between collaborative innovation and the financial performance of information technology (IT) firms through the mediating role of strategic agility and absorptive capacity. Customer knowledge management capability (CKMC) is also explored as a potential moderator.

Data were collected from 300 respondents working in different small to medium IT enterprises operating in different cities around Portugal. The simple random sampling method was used for data collection, and Smart partial least squares-structural equation modeling (Smart PLS-SEM version 3.2.8) was used to test the hypotheses.

The findings demonstrate that collaborative innovation contributes significantly to the financial performance of IT firms in Portugal. The results also indicate that absorptive capacity and strategic agility both positively and significantly affect the relationship between collaborative innovation and firms’ financial performance. However, while the moderating role of CKMC has a positive and significant effect on the relation between collaborative innovation and strategic agility, CKMC insignificantly moderates the relation between collaborative innovation and absorptive capacity.

Few studies have explicitly connected collaborative innovation with firms’ financial performance; this study attempts to fill that gap. Moreover, this research investigates the mediating role of strategic agility and absorptive capacity in the relationship between collaborative innovation and financial performance. Finally, by discussing the moderating effect of CKMC, which leads to enhanced financial performance, this study proposes that when complex and unpredictable situations occur, managers should focus on customer-oriented strategies and innovation at the same time to outpace their competitors.

The purpose of this paper is to know which hotels mostly rely on Booking.com, investigating the level of presence on Booking.com around the world by country, hotel size, hotel category and managerial form. Neither the company nor the hotels provide this information, so the authors use the number of reviews as an indicator of estimated sales.

Data from 33,996 hotels worldwide are downloaded from Booking.com using a Web browser automatically controlled, developed in Python, that simulated a user navigation (clicks and selections). The comparison between independent hotels and hotels belonging to a chain is performed by a Student’s t distribution test and the comparison of hotel categories and hotel size is analyzed by a one-way ANOVA test.

The results show that three factors clearly influence the usage level of Booking.com: independent vs chain hotels, small vs large hotels and low vs high category hotels worldwide. The authors also observe that hotels from Europe are the ones that rely more on Booking.com.

The originality of this research is to identify the factors that make hotels to have a greater (lesser) dependence on Booking.com within each destination and geographical area. Moreover, the use of big data from hotels worldwide allows the authors to know the level of use of Booking.com in dozens of countries, especially those with the highest tourist activity. This work expands the capabilities of big data in the hospitality industry research, and with a simple ratio, this study counteracts the lack of public data on hotel sales through Booking.com. This new approach could be extended to the analysis of other online travel agencies (OTAs), which use similar review systems.

This article aims to present aspects related to women’s personal life and work illustrated in the TV series Most Beautiful Thing (Coisa Mais Linda, in Portuguese).

To this end, a film analysis was carried out considering the first season of the TV series Most Beautiful Thing, and to analyze the data, qualitative content analysis was used according to Bardin (2006).

The analysis showed that women’s struggles were and are distinct. While white women are fighting for the right to work - concomitantly reconciling their roles as mother, wife and housewife -, black and poor women fight for survival and dignity. As result, the film analysis showed that women’s search for a different social position is related to an inherent cultural aspect. It is relevant to mention herein that this struggle remains up to the present; such struggle is characterized by the occultation of the social role played by women.

As a limitation, there are few studies that address the theme of white and black women during the period reported in the series.

The main contribution of this article is the use of a filming product that portrays the 1950s, but bringing current discussions on the role of women in society, especially regarding the labor market, the patriarchal domination of men, prejudice, racial, and class discrimination.

The purpose of this paper is to improve the surface finish and, therefore, the fatigue resistance of some endodontic files by electrochemical polishing; the influence of applying an autoclave’s sterilising cycle to the endodontic files under study was also assessed during the research herein presented.

In total, 22 Ni-Ti endodontic instruments of two sizes, namely, ref. Hyflex 0.04/20 and 0.06/20 (taper: 0.04; 0.06 and tip diameter: 0.20 mm, respectively), were submitted to rotational bending tests at 500 rpm; the radius and the angle of curvature imposed to the endodontic instruments during the experimental tests were equal to 4.7 mm and 45°, respectively. In addition, 18 endodontic files (out of the 22) were subjected to electrochemical polishing before in vitro fatigue tests had been carried out. Several combinations of electrochemical parameters were considered during the preliminary experiments involving electrolyte, voltage, flow rate and duration. The endodontic files under study were weighted using a high-precision balance before and after polishing, and mass variation was determined. Also, a sterilising cycle was applied to six polished endodontic instruments, which were placed inside an autoclave at 134°C, for 30 min, and under a pressure of 2.16 bar.

The fatigue resistance of as-received endodontic files ref. 0.04/20 is much larger (+480 per cent) than the fatigue strength of endodontic files ref. 0.06/20. The weight variation due to electropolishing was comprehended between 0.53 mg and 1.01 mg, and the fatigue resistance of all polished endodontic instruments increased between 30 per cent (0.06/20) and 80 per cent (0.04/20) when compared with the fatigue resistance of the as-received files. The application of an autoclave’s sterilisation cycle had a negative impact on the fatigue resistance of instruments ref. 0.04/20 and a positive impact on the durability of instruments ref. 0.06/20.

The application of an electrochemical polishing process increased the fatigue resistance of the endodontic files under study significantly, and the values for the variables of the electrochemical process were never published elsewhere. The surface finish improvement was obtained by immersing the endodontic files in a Struers’ Electrolyte (ref. E2) for 3 s while applying 30 volts and a flow rate of 1.

The interest on leader humor styles is recent. By applying a trustworthiness framework, the authors examine (1) how leader humor styles contribute to performance and deviance via trust in the supervisor and (2) who benefits/suffers the most from different leader humor styles.

The authors tested their hypotheses in a sample of 428 employee–supervisor dyads from 19 organizations operating in the services sector.

Affiliative and self-enhancing leader humor styles are particularly beneficial for employees with low core-self-evaluations, helping them develop trust in the supervisor and consequently improving their performance. An aggressive leader humor style, via decreased trust in the supervisor, reduces performance, regardless of employees' core self-evaluations. Self-enhancing and self-defeating leader humor styles also present significant relationships with organizational deviance.

Limitations include the cross-sectional design and the limited number of mechanisms examined.

Organizations need to train leaders in the use of humor and develop a culture where beneficial humor styles are endorsed, while detrimental humor styles are not tolerated.

These findings contribute to the literatures on trust and humor, by showing that the use of humor is not as trivial as one could initially think, particularly for those with low core self-evaluations, and by expanding our knowledge of the mechanisms by which different leader humor styles may influence performance and deviance.
