Destination attributes,satisfaction, and the cruise visitor's intent to revisit and recommend

The cruise industry has seen its revenues more than double since the year 2000. Hence, it has become even more important for planners and managers to pinpoint those destination attributes that make a difference in satisfying cruise ship passengers. This is especially crucial since the extant literature established that visitors' overall satisfaction with the destination strongly influences intent to return or recommend the destination to others. The purpose of this paper is to explore how the satisfaction of cruise visitors regarding various destination attributes may relate to their satisfaction with the destination and how this may influence declared intent of repeat visits or intent to recommend the destination to those within their social and professional networks. This study is based on the data collected for the island of Oahu in 2013 in Honolulu, Hawaii. Our analysis makes use of the logistic regression, and our results indicate that distance deters passengers from repeat visits, whereas the influence of satisfaction with the destination is positive not only for revisits, but also for word-of-mouth recommendations. Satisfaction with attributes such as transportation, safety and prices strongly influences satisfaction with the destination, whereas satisfaction with other attributes such as on-shore activities or sightseeing tours were found not to be as influential. The results delineate the factors planners and managers should focus on in their efforts to increase visitor satisfaction with a destination and thereby increase the likelihood of repeat visits and positive word of mouth.     

Optimal Control of Structures under Earthquakes Including Soil-Structure Interaction

It is well known that the soil-structure interaction (SSI) changes the dynamic response of a structure supported on flexible soil. The analysis of optimally controlled SSI systems has certain difficulties due to the nature of the SSI and the optimal control problem. In this paper, a two-step iteration-based numerical algorithm is proposed to handle optimally controlled SSI systems under earthquakes. First, the optimal control forces are obtained by using a fixed-base system. Then, the optimal control forces are converted to the frequency domain by the Fourier transform technique to be used in the equations of the SSI system. The lateral displacement and the rocking of the foundation are obtained from the equations of the SSI system containing the optimal control forces in the frequency domain. The lateral displacement and rocking of the foundation are then converted to the time domain by the inverse Fourier transform technique, and the lateral accelerations and the rocking accelerations of the foundation are obtained by the forward finite difference method. During the second step, the optimal control forces are calculated again by using the lateral acceleration and the rocking acceleration of the foundation along with the earthquake ground motion. Using the method explained above, the optimal control forces obtained in the time domain are used in the equations of the soil-structure system from which the behavior of foundation and structure is obtained. In the final section of the paper, a numerical study is conducted for a controlled structure supported on flexible soil.     

Dead missionaries,wild Sentinelese: An anthropological review of a global media event

This article aims to shed light on the background to a media event that occupied the world press, and even more the digital media, for a few weeks at the end of last year. The trope of the violent ‘murder’ of a white missionary by one of the last ‘uncontacted tribes’ is likely to evoke a variety of Western projections. Ultimately, it is about power over images, interpretations and how we want to behave towards isolated groups of people in today’s world: leave them alone? Protect them from the culture of violence at the fringe of their territories or contact them now and support them in the long term? An anthropological reading of the case does not lead to a simple answer to this question, but it might help in getting a more informed perspective on a complex subject matter.     

Social decision-making driven by artistic explore–exploit tension

We studied social decision-making in the rule-based improvisational dance There Might Be Others, where dancers make in-the-moment compositional choices. Rehearsals provided a natural test-bed with communication restricted to non-verbal cues. We observed a key artistic explore–exploit tension in which the dancers switched between exploitation of existing artistic opportunities and riskier exploration of new ones. We investigated how the rules influenced the dynamics using rehearsals together with a model generalized from evolutionary dynamics. We tuned the rules to heighten the tension and modelled nonlinear fitness and feedback dynamics for mutation rate to capture the observed temporal phasing of the dancers' exploration-versus-exploitation. Using bifurcation analysis, we identified key controls of the tension and showed how they could shape the decision-making dynamics of the model much like turning a ‘dial’ in the instructions to the dancers could shape the dance. The investigation became an integral part of the development of the dance.     

Some Discussions on Data-Driven Testing of Ground-Motion Prediction Equations under the Turkish Ground-Motion Database

Data-driven testing of ground-motion prediction equations (GMPEs) can help researchers in the ranking and selection of GMPEs for seismic hazard assessment. This paper presents and discusses the details of the major features of well-known testing methods which employ likelihood and Euclidean distance concepts. A set of local, regional, and global GMPEs are assessed under a ground-motion database. The data-driven testing of GMPEs is supported by thorough residual analyses under the database, providing valuable insights into the testing of GMPEs. The researchers are advised to evaluate all options together instead of focusing on a specific tool to build well-structured ground-motion logic trees.     

The Yenikapı 12 Shipwreck,a 9th‐Century Merchantman from the Theodosian Harbour in Istanbul,Turkey: construction and reconstruction

Shipwreck Yenikap? 12 was discovered in Yenikap?, Istanbul, Turkey in 2007 during rescue excavations carried out by Istanbul Archaeological Museums. The majority of the bottom of the shipwreck, found within the sediment‐filled Theodosian Harbour, is intact and part of the cargo was found in situ. According to the results of reconstruction studies, YK12 was a small merchantman working coastal waters, approximately 9.24m in length and 2.64m in breadth. The shipwreck is dated to the 9th century AD and was built with a mixed construction using the shell‐based method for the lower hull.     

The philosophy of westernisation: Ahmet Ağaoğlu on civilisation and culture

This article seeks to explore Ahmet A?ao?lu's understanding of the concepts of ‘civilisation’ and ‘culture’ and his approach to the question of Westernisation, with the aim of shedding light on the intellectual background of the westward transformation of Turkey. A?ao?lu attempted to define and describe these concepts at a time when a nation-building process was taking place in Turkey. The study traces the evolution of, and the relationship between, A?ao?lu's later Westernist and nationalist ideas which were in constant interplay with each other, and concludes that A?ao?lu saw a symbiotic relationship between one's changing civilisation and cultural enrichment.
