The Impact

A great deal of attention has recently been paid to the semi-empirical modelling, nonlinear response prediction and estimation of stress and fatigue damage of marine risers undergoing vortex-induced vibrations (VIV). This is because when as the offshore industry move into deeper waters, the impact of VIV caused by ocean currents becomes detrimental being one of great concerns for offshore operators and riser engineers. For computational efficiency in time domain, the van der Pol wake oscillator, coupled with the structural equation of motion, has been an attractive approach. However, wake oscillator models rely on empirical coefficients, which have uncertainties whose effect on the fatigue reliability is not well understood. This study focusses on the wake oscillator proposed by Skop and Balasubramanian (1997). Using a top-tensioned riser model, a sensitivity study is performed on several random variables to determine their influence on the uncertainty of the fatigue damage. These variables include the maximum vibration amplitude, frequency ratio, damping ratio and lift coefficient. In addition, Monte Carlo simulations are conducted to predict the probability of failure.

The Impact

Purpose – The purpose of this paper is to extend research on employer branding in the recruitment context. The authors develop a model that integrates research from employer branding, social identity theory, and person-organization fit in order to investigate the impact of company reputation and identity congruency between organizations and their job applicants on the attractiveness of an employer brand. Design/methodology/approach – An online survey was conducted to test the theoretical model in a recruitment context in the Norwegian offshore industry. Structural equation modelling is employed in the data analysis. Findings – A key finding is that a company’s reputation and identity congruence between applicants’ self-identities and their perceived organization identity affect job applicants’ job pursuit intentions through mediation of cognitive social identity. Moreover, identity congruence predicts applicants’ cognitive identification with the company. Practical implications – The study suggests that managers should try to map and understand central characteristics that describe job applicants’ identities and strive to provide applicants with access to necessary information about the company to form cognitive identification with the company. Originality/value – The authors extend research on employer branding by incorporating social identity and attitude as mediators between symbolic and instrumental attributes of an employer brand and its attractiveness. This study also deepens research on social identity by including explicitly a comparison process between applicants’ self-identities and their perceived organizational identity, which leads to applicants’ identification with the company.

The Impact

The Swiss Armed Forces (SAF), as part of a democratic system, depends on legitimacy. Democracy, legitimacy and the public are closely connected. In the public sphere the SAF need to be visible; it is where they are controlled and legitimated by the citizens, as part of a deliberative discussion in which political decisions are communicatively negotiated. Considering this, the meaning of political communication, including the SAF’s communication, becomes obvious as it forms the most important basis for political legitimation processes. Social media provide a new way for the SAF to communicate and interact directly with the population. The SAF’s social media communication potentially brings it closer to the people and engages them in a dialogue. The SAF can become more transparent and social media communication may increase its reputation and legitimacy. To measure the effects of social media communication, a survey of the Swiss internet population was conducted. Based on this data, a structural equation model was defined, the effects of which substantiate the assumption that the SAF benefits from being on social media in terms of broadening its reach and increasing legitimacy values.

The Relationship

There is continuous debate on the impact of house quality on residents’ health and well-being. Good living environment improves health, and fear of crime is recognised as a mediator in the relationship between physical environment and health. Since minimal studies have investigated the relationship, this study aims to examine the impact of the house quality on fear of crime and health. A total of 230 households from a residential neighbourhood in Malaysia participated in the study. Using structural equation modelling, the findings indicate that housing quality and fear of crime can account for a proportion of the variance in residents’ self-rated health. However, there is no significant relationship between housing quality and fear of crime. Results also show that fear of crime does not mediate the relationship between housing quality and health. This study suggests that the environment-fear relationship should be re-examined theoretically.

The Impact

This study aims to investigate the impact of parental career behaviors on undergraduate student’s career exploration and the mediating role of career self-efficacy. In the literature it is suggested that some social and individual factors facilitate students’ career exploration. Therefore, parental career behaviors and career self-efficacy is considered as predictors of student’s career exploration attitudes within the scope of the study. In this respect, data which are collected from 405 undergraduate students having an education on tourism and hotel management field by the survey method are analyzed by using the structural equation modeling. The results of the study indicate that parental career behaviors which are addressed support; interference and lack of engagement have a significant effect on student’s career exploration behaviors such as intended-systematic exploration, environment exploration and self-exploration. In addition, it has been found that one of the dimensions of parental career behaviors addressed as a lack of engagement has a significant effect on career self-efficacy levels of students. However, research results indicate that student’s career self-efficacy has a significant effect on only the self-exploration dimension. On the other hand, career self-efficacy has a partial mediating role between lack of engagement attitudes of parents and career exploration behaviors of students.

This paper aims to explore the impact of a hotel’s reward system on strengthening: positiverelationships and communication among employees; the creation of a change-friendlyorganisational climate and cultural change barriers, within the context of a cultural changeprocess in a hotel. Quantitative data were collected from a proportionally stratified,representative sample of 207 Greek five-star hotels’ senior executives and analysed with theprincipal component method of extraction and Structural Equation Modelling. This led to thecreation and validation of three prototype second-order latent variable models, whichhighlight and depict the impact of individual variables and their importance for a rewardsystem creating an organisational climate for or against cultural change in hotels. Theoriginality of the paper lays on both theoretical and practical levels. On a theoretical level, thepaper’s findings manage to fill a knowledge gap through a novel modelling of a rewardsystem on a hotel’s organisational climate in times of cultural change. On a practical level, thepaper findings enable hotels’ executives to focus on specific variables of a reward system thatcan enhance and/or prevent a cultural change initiative.

The Impact

This research explores the impact of service satisfaction, relational satisfaction, price satisfaction, and commitment on customer loyalty in logistics outsourcing relationships in Indian scenario. 254 users of logistics services from India were selected for investigating the potential linkages among the aforementioned satisfaction aspects and loyalty. Structural equation modeling (SEM) was employed to test the reliability and validity of the measurement and structural model developed to study the relationship among the linkages. Findings from the study supports that logistics service satisfaction, price satisfaction, relational satisfaction and commitment do influence loyalty positively. The analysis suggests that service satisfaction is the most important antecedent having primary influence in the formation of customer loyalty. Service satisfaction also has secondary influence on loyalty by acting as a strong driver in both relational satisfaction and commitment aspects of the service dimensions. Price satisfaction though positively been driven by service satisfaction, was found to have less significant effect as a predictor of loyalty in this context. The present study suggests that relational satisfaction is the second major predictor of loyalty which also drives commitment. This research is not an end-point but an attempt to establish the linkages and the effect among the antecedents driving the building and retention of good buyer-seller relationship in logistics outsourcing.
