This study aims to examine the effects of different dimensions of national culture on corporate social responsibility (CSR) activities of hospitality firms, including lodging, casino and restaurant firms.

This study performs a panel regression analysis to examine the effect of Hofstede’s national culture dimensions on the total CSR score, positive CSR score and negative CSR of the sampled hospitality firms. The sample period spans fiscal years 1993 to 2011and 365 firm-year observations are used for the study’s analysis.

This study finds a positive and significant effect of uncertainty avoidance on the total CSR score. Further, the study’s results show a positive and significant effect of power distance both on positive and negative CSR scores, while individualism appears to have a negative and significant effect both on positive and negative CSR scores. Masculinity reveals a negative and significant effect on the positive CSR score.

Although the study’s results may not be generalizable to private or non-hospitality firms, according to the findings, multinational hospitality firms are encouraged to conceive a CSR portfolio consisting of localized CSR strategies that consider the effects of national culture on CSR.

This study contributes to the body of hospitality literature by filling the void regarding the relationship between national culture and CSR. At the same time, the findings of this study serve as guidelines for multinational hospitality firms’ implementing CSR activities.

This paper reports on the design of a knowledge base for an automatic classification in the library science field, by using the facet classification principles of colon classification (CC). To do so, by designing and constructing a knowledge base that is able to be classified automatically, and by inputting titles or key words of volumes into the computer, it aims to create class numbers automatically through automatic subject recognition and processing of key words in titles through the facet combination method of CC. Especially, the knowledge base for classification was designed along with the principle of globe and cylinder, automatic classification which can be possible.

The purpose of this study is to investigate the moderating role of CEO duality on the geographic diversification–firm performance relationship in the US lodging industry.

To examine the individual effect of geographic diversification and the moderating effect of CEO duality, this study adopts random effects regression. Additionally, to appropriately address the endogeneity issue, this study uses random effects regression with the instrumental variable method. The sample period spans 1990-2015 and 258 firm-year observations are included.

This study finds that geographic diversification has a positive and significant effect on firm performance. Also, the result shows a positive and significant moderating role of CEO duality, which implies that the magnitude of the impact of geographic diversification on firm performance is significantly greater when CEO duality exists.

Although it has a limitation of applying the results of this study to privately held lodging firms in other countries, US public lodging firms are encouraged to consider a corporate governance structure incorporating CEO duality to maximize the effect of geographic diversification on firm performance.

This study contributes to the hospitality literature by providing a unique dimension that the influence of geographic diversification is contingent on the adoption of CEO duality. And, the results of this study provide practical guidelines for the lodging firms’ implementation of geographic diversification.

This study argues that the literature on public‐private distinction has failed to distinguish among different types of organizational culture found in the public sector, while recognizing other important differences. Drawing upon a distinctive bureaucratic culture in South Korea, this study seeks to examine Korean public and private managers' perceptual and attitudinal differences associated with their levels of organizational commitment. Influenced by Confucian values and experience with past military regimes, Korean public managers score higher on their perceived job prestige and perceived centralization than do their counterparts in the private sector. No significant differences are found in the dimensions of commitment to stay, job satisfaction, and perceived inequity between the two sectors. This study also reveals that one of the powerful antecedents of organizational commitment in the Korean public sector is the job prestige perceived by public managers. Finally, implications are discussed.

In the past few years, HB-like protocols have gained much attention in the field of lightweight authentication protocols due to their efficient functioning and large potential applications in low-cost radio frequency identification tags, which are on the other side spreading so fast. However, most published HB protocols are vulnerable to man-in-the-middle attacks such as GRS or OOV attacks. The purpose of this research is to investigate security issues pertaining to HB-like protocols with an aim of improving their security and efficiency.

In this paper, a new and secure variant of HB family protocols named HB-MP* is proposed and designed, using the techniques of random rotation. The security of the proposed protocol is proven using formal proofs. Also, a prototype of the protocol is implemented to check its applicability, test the security in implementation and to compare its performance with the most related protocol.

The HB-MP* protocol is found secure against passive and active adversaries and is implementable within the tight resource constraints of today’s EPC-type RFID tags. Accordingly, the HB-MP* protocol provides higher security than previous HB-like protocols without sacrificing performance.

This paper proposes a new HB variant called HB-MP* that tries to be immune against the pre-mentioned attacks and at the same time keeping the simple structure. It will use only lightweight operations to randomize the rotation of the secret.

The current adverse changes in climatic conditions have necessitated innovative nature-based solutions like blue-green roofs to ensure sustainable built environments. The use of blue-green roofs in combating climate change issues has continued to grow, and its benefits are showcased in many countries' studies. However, there is an absence of reports on the use of this approach in South Africa. Therefore, in ensuring a sustainable built environment through nature-based solutions, this study explored the built environment professional’s knowledge of blue-green roofs, the hindrances to their use and motivations for much wider use of blue-green roofs in the country.

Based on the nature of the study, a quantitative design was adopted and data were obtained from professionals within the built environment through a questionnaire. Data analyses were conducted using the Cronbach alpha test, Kruskal–Wallis H-Test, exploratory factor analysis and fuzzy synthetic evaluation.

The findings revealed a growing knowledge of blue-green roofs, albeit its slow adoption in the country. Also, five critical clusters of hindrances affecting the use of blue-green roofs were identified. These are understanding the blue-green roof concepts, technical, economic, regulation and client hindrances. Furthermore, the ability to manage stormwater properly, provide climate change adaptation and deliver sustainable buildings were the key motivating factors that could drive the use of this innovative solution.

This study offers actionable insights for built environment professionals and stakeholders to address the hindrances to using blue-green roofs in South Africa. Strategies such as improved education, financial incentives and policy development can help overcome some notable hindrances and promote the widespread adoption of blue-green roofs.

The slow adoption of blue-green roofs and the scant nature of research within the built environment required adequate attention to which this current research contributes. Theoretically, being one of the foremost studies in South Africa to explore blue-green roofs, the findings offer a foundation for future studies seeking to explore this roofing system in the country further.
