A methodology for producing an elevated-temperature tension stiffening model is presented.

The energy-based stress–strain model of plain concrete developed by Bažant and Oh (1983) was extended to the elevated-temperature domain by developing an analytical formulation for the temperature-dependence of the fracture energy G_f. Then, an elevated-temperature tension stiffening model was developed based on the modification of the proposed elevated-temperature tension softening model.

The proposed tension stiffening model can be used to predict the response of composite floor slabs exposed to fire with great accuracy, provided that the global parameters TS and K_res are adequately calibrated against global structural response data.

In a finite element analysis of reinforced concrete, a tension stiffening model is required as input for concrete to account for actions such as bond slip and tension stiffening. However, an elevated-temperature tension stiffening model does not exist in the research literature. An approach for developing an elevated-temperature tension stiffening model is presented.

Effectiveness of message tactics in social marketing projects often varies across groups of individuals, which suggests the importance of tailoring communication approaches to maximize the success of promotional strategies. This study aims to contribute in this direction by using an innovative approach to promote targeted human papillomavirus vaccination, applying conjoint analysis to understand parental preferences for social media content features.

An online purpose-built quantitative survey was administered to a group of parents meeting eligibility criteria. The survey questions were designed based on inputs from formative qualitative research conducted in a previous phase of the study.

In the overall sample of 285 parents, responses show that image was the most important feature of social media posts overall, followed by source and text. Cluster analysis identified eight segments in the sample based on parental preferences for content features. Significant differences across segments were identified in terms of need for cognition, vaccine hesitancy, parental gender, concerns around side effects, trust in medical providers, information sharing behaviors on social media and information seeking online.

The application of conjoint analysis to promotional content allows to assess which features of the content are most important in persuading different individuals and provide insights on how people process the information, ultimately to inform targeted promotion based on preferences. Conjoint analysis has been widely used in consumer research to explore audience preferences for products or services, but only a few applications of conjoint analysis to the design and testing of promotional content are found in the literature.

Racialization is an important concept when looking at structural mechanisms that perpetuate racial inequalities. The State, and its various organizational spaces of action, is often seen as a site for race to be enacted. Policy sectors such as housing, education, taxation, and immigration have been ripe areas of research that reflect this. However, media policy research has not effectively engaged with this critical conception. Media policy research has been driven by political economy perspectives within the field of Mass Communication and Media Studies, and can benefit from an approach that analyzes it in relation to social science perspectives that focus on processes which constitute, or are constituted by, actors, groups, and organizations. Our hope is that future researchers will find this volume useful in further developing critical studies of media policy that take into account race as a social force.

This conversation presents the reflections from six international disaster scholars on how disaster capitalism manifested in very different ways in different countries, including Japan, Chile, Brazil, Colombia, India and South Africa, during the COVID-19 pandemic. The purpose of this paper is to address this issue.

This paper is based on the conversations that took place on Disasters: Deconstructed Podcast livestream on the September 15, 2020.

The prominent themes in this conversation include profiteering, oppression and the politics of disasters.

The conversation contributes to the ongoing discussions around disaster capitalism and disaster risk creation.

Leadership has been deeply studied in the literature; however, little research exists studying the role of volunteer peer leaders in non-formalized leadership roles in membership-based organizations. This phenomenological study was designed to explore the experience of beef industry leaders in leadership roles. Twelve active beef industry volunteer leaders were interviewed and described their experience as leaders. Industry leadership was defined from study themes as a role fulfilled by someone who is willing to serve their industry, with the best of the industry in mind and taking on the responsibility and challenges that come along with making decisions to serve and speak for their peers with integrity. Seven themes identified the central phenomenon and seven traits of beef industry leaders were identified. This study offers significance to the field of leadership; to the beef industry; and to agricultural organizations that may guide developing future leaders.

In the competitive retailing environment, retailers who provide service experiences that stand out from the competition can gain a competitive advantage. Increasingly, an important aspect of the service experience involves product returns, in particular, the fairness of returns policies and procedures. Previous research studies support that interpersonal justice and informational justice relate positively to consumer attitudes and behaviors. In this paper, the authors examine the relative effects of interpersonal justice and informational justice on return satisfaction, positive word-of-mouth (PWOM) and trust. Additionally, the authors examine the moderating effects of returns process convenience and returns policy restrictiveness as indicators of procedural justice.

A scenario-based experiment methodology was used to test the relationships of interest.

Results support that the effects of interpersonal justice on the outcome variables are stronger than the effects of informational justice. There is also support for a moderating effect of returns process convenience on the relationships between interpersonal justice and each outcome variable, as well as partial support for the moderating effect of returns policy restrictiveness on the relationship between interpersonal justice and PWOM.

The research extends previous work on the effects of justice on customer outcomes. Results support the importance of retailers treating customers with fairness during the returns experience and further support the benefits of providing a convenient returns experience.

To explore the cultural context of Indigenous family entrepreneurs and to apply to them the concept of n-Culturals, thus contributing to validating the concept.

Interview data collected from Wayuu entrepreneurs in La Guajira region of Colombia and from Māori entrepreneurs in the Rotorua region of New Zealand were analyzed qualitatively. The analysis primarily focused on Wayuu entrepreneurs, with the results for Māori entrepreneurs used for comparison, to help to interpret the Wayuu data.

For Wayuu entrepreneurs, family members play a range of crucial roles in enterprise operations, with the family and the kin-centered local Indigenous community emerging as an informal organization surrounding the enterprise. Family is the source of Indigenous culture, while the mainstream culture is centered on global Western business culture, rather than the culture of the country. The Indigenous entrepreneurs integrate the values of the two cultures in managing their enterprises, thus acting as n-Cultural. Māori entrepreneurs who managed enterprises with a strong Indigenous character were similar in this respect to Wayuu entrepreneurs.

As n-Culturals integrating the values of Indigenous culture and the mainstream culture, Indigenous entrepreneurs develop valuable traits, becoming a valuable component of the human capital in their regions, even when their enterprises fail.

Existing research on multicultural individuals is largely limited to immigrants and expatriates. By characterizing Indigenous family entrepreneurs as n-Culturals, the present study contributes to validating the concept and opens the way for further research on how Indigenous entrepreneurs manage their multicultural identities.

This paper aims to analyze the publication structure of academic research on green innovation (GI) between 2000 and 2019.

Bibliographic data on GI are extracted from the Scopus database, and then they were analyzed through VOSviewer software.

This paper analyzes 653 publications on GI from 2000 to 2019. For so doing, the study identifies the most productive countries, universities, authors, journals and the most prolific publications in GI. Besides, the study uses VOSviewer software to visualize the mapping based on co-citation, bibliographic coupling (BC) and co-occurrence of keywords.

The main contribution of the study is that it provides an overview of the trends and trajectories of GI, which may help the researchers and the practitioners to comprehend the trends and future research directions.
