The relationship between the search problem and entropy identified by Pierce is used to show that the entropy maximization technique can also be applied to the data distribution problem. An immediate result is that a previously validated entropy model for the data distribution problem can now be more formally developed.

A framework based on the database entropy concept developed for characterizing the learning process of a database is applied to the dynamic measurement of the promptness and coherence of a distributed database. The results can be of great value in the design and implementation of self‐adaptive distributed databases.

A framework based on the entropy concept for characterizing the learning process of a database is developed. Such a framework can prove to be useful not only in analyzing existing databases and the design of self‐adaptive databases, but also in providing a basis for a unified approach to tackling a variety of related database problems.

Traditional Chinese medicine (TCM) had a long history and has been widely practiced worldwide. TCM includes acupunctures, herbal medicine and chiropractic. However, limited studies examined the relationship between knowledge, attitude, utilisation and satisfaction of TCM among the Hong Kong general public. This study has developed a research model which aims to examine the relationship between knowledge, attitude, utilisation and satisfaction of TCM in Hong Kong by using partial least square structural equation model.

An online-based questionnaire was distributed by using convenience sampling. The questionnaire consisted of five parts to collect the data regarding the knowledge, attitude, utilisation and satisfaction of TCM of respondents. The reflective measurement model and structural model were examined with SmartPLS 3.0 statistical software.

A total of 131 respondents completed the survey, and all data were valid after data screening and cleaning. Around 60% of the participants received TCM information from their friends and family members, and 42% from the internet. Likewise, there is positive relationship from the knowledge of TCM to the utilisation, from the attitude to the utilisation and from the utilisation of TCM to the satisfaction. However, the positive relationship of knowledge regarding TCM and attitude is not proven. A t-test and one-way analysis of variance showed no significant differences between gender and age groups on each measurement items.

This paper provides insights for researchers and policymakers to understand the significance of attitude and perception of the benefits of treatments in the use of TCM. The positive experience of TCM from other people is essential for enhancing the willingness to use TCM while education is also fundamental in promoting TCM to the public.

This study is a theory-building effort to extend the risk perception attitude (RPA) framework by considering an organization-related factor. Specifically, this study examined how an organization-related factor, namely safety climate, and individual-related factors, namely risk perception and efficacy belief, jointly influence flight attendants’ occupational health and safety (OHS) information seeking intent.

About 486 flight attendants from an international air carrier, based in Hong Kong, participated in an online survey. Hierarchical regression was employed to examine the three-way interaction of risk perception, efficacy belief, and safety climate.

Results showed that safety climate moderated the effect of efficacy belief on the relationship between risk perception and OHS information seeking intent. For flight attendants who perceived a high safety climate, those who felt more efficacious had a higher intent for OHS information seeking than those who felt less efficacious. In contrast, for flight attendants who perceived a low safety climate, when they perceived a high level of risk, those with low efficacy had a higher information seeking intent than those with high efficacy.

Although the RPA framework has shown its potential to explicate how individual employees engage in OHS information seeking behavior, the framework has largely overlooked the importance of organization-related factors as an influential shaping force of individual employees’ behavior. To fill this research gap, this study extends the RPA framework by examining how safety climate moderates the relationship between risk perception and efficacy belief on flight attendants’ OHS information seeking intent. Safety climate also plays an important role in segmenting audience groups for OHS promotion.

Racialized minority and newcomer communities are over-represented in positive HIV cases in Canada. Stigma has been identified as one of the barriers to HIV prevention, testing, and treatment. Faith, media, and social justice sectors have historically served a vital role in promoting health issues in these communities. However, they have been relatively inactive in addressing HIV-related issues. The purpose of this paper is to report on the results of an exploratory study that engaged faith, media, and social justice leaders in the African-Caribbean, Asian, and Latino communities in Toronto.

This study used a qualitative interpretive design and focus groups to explore the challenges and opportunities in addressing HIV stigma. A total of 23 people living with HIV and 22 community leaders took part in seven focus groups. Intersectionality was used as an analytical lens to examine the social processes that perpetuate HIV stigma.

This paper focuses on the perspectives of community leaders. Five themes were identified: misconception of HIV as a gay disease; moralistic religious discourses perpetuate HIV stigma; invisibility of HIV reinforces community denial; need to promote awareness and compassion for people with HIV; and the power of collective community efforts within and across different sectors.

Although affected communities are faced with many challenges related to HIV stigma, effective change may be possible through concerted efforts championed by people living with HIV and community leaders. One important strategy identified by the participants is to build strategic alliances among the HIV, media, faith, social justice, and other sectors. Such alliances can develop public education and HIV champion activities to promote public awareness and positive emotional connections with HIV issues, challenge HIV stigma and related systems of oppression, and engage young people in HIV championship.

This study aims to improve disaster management. Social media, particularly microblog, has become a new platform for public opinion dissemination. However, few studies have been conducted to explore the structure of public opinions, the approaches for facilitating the spread of public opinions and the results of public opinion dissemination in the context of mobile internet for the purpose of improving disaster management.

This paper chooses Ebola as the research topic and extracts 14,735 Ebola-related data items from Sina Microblogs to examine the information nodes of public opinion and the characteristics of propagation paths on mobile internet. Particularly, nodes of public opinion between mobile terminals and non-mobile terminals are compared.

The results of this paper reveal the characteristics of public opinion propagation on mobile internet and verify the effectiveness of public opinion propagation on mobile internet. This study shows that public opinions propagate quickly, widely and efficiently and further generate great impacts on mobile internet.

The methods used in this study can be useful for the government agencies and other relevant organizations to monitor public opinions, identify issues and problems proactively and develop strategies in a more efficient manner to improve disaster management.

The results of this paper are helpful for related departments to monitor public opinions and to further improve disaster management.

This paper explores the mechanism of public opinion dissemination on mobile internet and further investigates how to improve disaster management through a case study related to Ebola.

The purpose of this paper is to study how project-level performance mediates the effect of project management assets on firm-level performance by examining the direct and mediated relationships between the project management process characteristics: valuable, rare, inimitable and organizationally supported on project-level and firm-level performance outcomes.

This paper analyzes data from an online survey completed by 198 North American Project Management Institute® members. Linear regression and Sobel Tests are used to examine the relationships between nine factors extracted from an exploratory factor analysis that comprise project management asset characteristics, one factor that comprises project-level performance outcomes, and one factor that comprises firm-level performance outcomes.

Not only does project-level performance positively and significantly affect firm-level performance, but project-level performance also significantly mediates the effect of project management asset characteristics (for all nine factors) on firm performance.

Limitations of this study include sample size and self-report bias, calling for a larger sample in ongoing research.

This study contributes to the stream of literature on project management assets as sources of competitive advantage and makes the case for sustained organizational investments in the project management process.

This paper contributes to the limited, but increasing interest in applying the resource-based view of the firm to project management capabilities as a source of competitive advantage.

This research seeks to simultaneously test the effect of attitude towards the behavior of following the “Stay at Home” policy, subjective norm, perceived behavioral control, perceived susceptibility and perceived severity on people's intention to follow the “Stay at Home” policy during COVID-19 pandemic.

The data were collected through an online survey with 148 respondents in the Greater Area of Jakarta, Indonesia. The data were then analyzed using multiple regressions.

The findings show that attitude towards the behavior, subjective norm and perceived behavioral control positively and significantly affect intention to follow “Stay at Home” during the COVID-19 pandemic. However, perceived susceptibility and perceived severity of COVID-19 do not significantly influence the intention to follow “Stay at Home” during the COVID-19 pandemic.

This research was limited to the Greater Area of Jakarta, Indonesia. Furthermore, sampling was done through convenience sampling. Therefore, future research should be conducted in a different context to test the generalization of this research's findings.

To encourage citizens' adherence to the stay-at-home policy during the COVID-19 pandemic, they must be directed to have positive attitudes toward the policy. Financial and non-financial supports are critical to ensure citizens' ability to sufficiently observe the policy sufficiently. Another important aspect is the influence of leaders and public figures to consistently call for obedience consistently.

This is the first research that studies citizens' behavior related to the “Stay at Home” policy requisitioned by the government to hinder the spread of COVID-19.

The aim of this paper is to examine the links between project management process characteristics and project-level and firm-level performance outcomes to test the hypotheses that project management assets being valuable, rare, inimitable and having organizational support leads to competitive advantage.

This paper analyzes data from responses to an online survey by 198 North American Project Management Institute® members. Regression analysis is used to examine the relationship between six factors extracted from an exploratory factor analysis that comprise the three project management asset characteristics – valuable, rare and inimitable, three factors that comprise organizational support for the project management process, and two factors that comprise project management performance outcomes – project-level and firm-level performance.

Organizational support for the project management process, specifically project management integration, was found to significantly contribute to both project-level and firm-level performance. Of the asset factors examined, valuable project management knowledge was found to contribute to project-level and firm-level performance, though information technology (IT) tools did not. Inimitable proprietary tangible assets were found to contribute to both project-level and firm-level performance, and inimitable embedded intangible assets were also found to contribute to firm-level performance. Rare knowledge sharing tools and techniques were found to negatively contribute to project-level performance.

Limitations of this study include sample size, response rate and self-report bias, calling for a larger sample in ongoing research.

This study draws managerial attention to project management assets as sources of competitive advantage, highlighting the need to have organizational support for the project management process through organizational integration, and emphasizing the importance of valuable project management knowledge-based assets and inimitable project management assets that are proprietary and tangible as well as those that are embedded and intangible.

Few papers have applied the resource-based view of the firm to examine project management capabilities as a source of competitive advantage. This paper contributes to the literature on the resource-based view of the firm and to an improved understanding of project management as a source of competitive advantage.
