Cruise tourism is a dynamic, growing segment of tourism that has long ceased to represent a mere niche and is slowly but steadily entering the domain of mainstream tourism. Yet, cruise tourism represents a minor fraction of tourism-related literature and research (Papathanassis and Beckmann, 2011). This study aims to examine the main trends and state-of-the-art developments in cruise tourism. The intension is to provide a starting point, a basis for non-specialists in this area, for further interdisciplinary research.

Using the author’s previous research and expertise over the past decade, this paper aims at providing a concise overview of the key perspectives and concepts in cruise tourism, whilst highlighting the current and future challenges faced by the sector and its stakeholders.

In this context, the potential of information and communication technologies for cruise tourism development and research (e-cruising) is underlined.

Finally, this paper offers a comprehensive systemic definition of cruise tourism and the corresponding Cruise Entities, inter-Relationships and Themes (CruisERT) framework, highlighting relevant areas and questions for further research.

This paper aims to conduct a review on cruise shipping and the cruise shipping industry. The current trends are analyzed for the industry, showing that this industry is still young and has great potential to boom. Meanwhile, the Asia market is the fastest growth region among the global, to which increasing cruise ships are repositioned by major cruise lines. However, for such a promising industry, the literature review on some state-of-the-art research works suggests that the research works that have been conducted for the cruise shipping are quite limited, and the majority of the works belongs to empirical and descriptive studies, which does not provide optimization-based quantitative analysis on some operation planning problems.

This paper conducts a review on cruise shipping and the cruise shipping industry.

In reality, there are some important operation planning problems faced by cruise lines or cruise ships, and four of them are addressed in this paper in response to the fast growing trend. The addressed operation planning problems are cruise fleet management, cruise ship deployment, cruise itinerary design and cruise service planning.

The importance and the attention for the research on the problems are also elaborated in the paper.

The very large number of books at present being issued relating to, or connected with the War, conclusively shows to what a great extent the intellectual as well as the material strength of the nation is engrossed by the terrible struggle in which we are engaged. But without abating any of our own interest in the supreme events now taking place, we may well pause to remember that things will not always be thus, and consider carefully before we crowd our shelves with works that are in many cases of very ephemeral value.

The main purpose of this study was to determine the basic aerodynamic characteristics of the airliner Tu-154M at the wide range of the overcritical angles of attack and sideslip angles, i.e. α = −900° ÷ 900° and β = −900° ÷ 900°.

Wind tunnel tests of the Tu-154M aircraft model at the scale 1:20 were performed in a low-speed wind tunnel T-3 by using a six-component internal aerodynamic balance. Several model configurations were also investigated.

The results of the presented studies showed that at the wide range of the overcritical angles of attack and sideslip angles, i.e. α = −900° ÷ 900° and β = −900° ÷ 900°, the Tu-154M aircraft flap deflection affected the values of the drag and lift coefficients and generally had no major effect on the values of the side force and pitching moment coefficients.

The model vibration which was the result of flow separation at high angles of attack was the wind tunnel test limitation.

Studies of the airliner aerodynamic characteristics at the wide range of the overcritical angles of attack and sideslip angles allow assessment of the aircraft aerodynamic properties during possible unexpected situations when the passenger aircraft is found to have gone beyond the conventional flight envelope.

There are no social implications of this study to report.

The presented wind tunnel test results of the airliner aerodynamic characteristics at overcritical angles of attack and sideslip angles is an original contribution to the existing not-too-extensive database available in the literature.

To examine how shareholding affects optimal profits, R&D innovation, NEV market scale and social welfare in two supply chain models with partial and cross ownership patterns.

The gradual retreat of government subsidies has directly weakened the financial support available to the stakeholders of new energy vehicles (NEVs). In this context, upstream and downstream enterprises of NEV are constantly seeking new business models of cooperation to achieve possible win-wins. NEV supply chain shareholding is an emerging new practice for such explorations. However, its performance in the NEV supply chain is seldom investigated. In this paper, we employ a Stackelberg game model to investigate how partial and cross-ownership affect the optimal decisions in a NEV supply chain.

Results showed that: (1) Compared with the unilateral shareholding model, the battery supplier will benefit from cross-ownership in the supply chain, while the NEV manufacturer will not necessarily benefit from it. At the same time, cross-ownership will bring the greatest incentive for battery R&D (2) Supply chain downstream competition will not necessarily lead to the improvement of the total consumption of NEVs or the level of battery design. Pareto improvement can be brought only when one of the manufacturers holds less than a certain equity threshold. In addition, downstream competition will also not necessarily bring more benefits to the battery supplier.

At present, NEV supply chain management has attracted widespread attention from scholars from all walks of life. Previous studies have been carried out that covers topics such as pricing strategies and optimal profits and the role of NEV in the sustainable development of the automotive industry supply chain, or disparate impacts of government subsidies and carbon emission regulation on supply chain members. However, as far as the authors know, compared with the new emerging NEV corporate practice, the shareholding phenomenon between upstream and downstream in the supply chain of NEV has not been studied in the existing studies.

The purpose of this paper is to investigate, through metaphor analysis, the complex nature of the work undertaken by waiters and pursers on-board cruise ships. This is an under-researched field and empirical research has produced some interesting perceptions that these groups of workers have of themselves, of others, and of the world in which they work and live.

A total of 20 semi-structured interviews were conducted over the telephone from a sample of international participants. The data were analysed using a metaphor analysis.

There were three clusters of metaphorical illustration found: metaphors of the ship, metaphors of the environment, and metaphors of their occupation. The metaphors of the environment were split into two sub-clusters. One explored how participants understood the ship's space or work setting, and the second identified the strategies used as participants negotiated their way through their working and social lives. The stories collected from the workers have produced a very different but realistic perspective of the working lives of waiters and pursers.

Metaphors can only offer a partial view of a social phenomenon, rather than an all-encompassing view, which are furthermore specific to the research setting. Notably, for half of all participants English was not their first language, and consequently this may have had an impact upon their use of metaphors.

This research highlights the socio-employment relationship and complexities of working on cruise ships. In particular, it recognises behavioural learning practices and organisational bureaucratic utilities, which the industry relies upon for managing employees.

This study contributes new knowledge in an under-researched context exploring the sociological lives of hospitality cruise ship workers. The use of metaphor analysis has provided an interesting and useful route to extend understanding of cruise ship work.

LIBRARIES are not a first priority in the building programme of the nation. It would be difficult to make them so. The Library Association Council, we are assured, have this matter under consideration continually and will lose no opportunity to urge the need for extensions of old buildings and for new ones. The demand for libraries grows, in the face of other needs, at a pace which is both a pleasure and an embarassment to librarians. Some authorities have made provision for new libraries this year in budgets which come under consideration this month, and we hope the Ministry concerned will allow some of these projects to be realized.

The purpose of this study is to provide the description of a computational methodology to model the combined propulsive systems of hydrogen propelled air-breathing scramjet vehicles and to evaluate the pollutant and climate-changing emissions.

Emissions indexes of nitrogen oxide (EINO) and water vapour released by the air turbo rocket (ATR) and dual mode ramjet (DMR) engines of the STRATOFLY air-breathing, hypersonic scramjet vehicle, propelled by hydrogen/air were evaluated. ATR engine operation was assessed for several cruise conditions in both subsonic and supersonic flight regimes in Ecosimpro software, which is an object-oriented thermodynamic design and simulation platform. ATR combustor inlet flow conditions play a key role in the computation of species mass fractions, and these conditions are highly dependent on turbomachinery performance and engine flight regime. A propulsive operational database was created by varying mass flow rates of fuel and flight conditions such as cruise speed and altitude to investigate possible engine operations. The all-inlet conditions in this map are provided to the Cantera-Python chemical/combustion chemistry solver implementing a specially designed and formulated 0D kinetic-thermodynamic methodology successfully used to model and simulate the electric spark ignition required to activate the combustion process of the reacting mixture in the ATR combustion chambers, whereas the coupled aero-thermodynamic/aero-propulsive 0D/1D code i.e. Scramjet PREliminary Aerothermodynamic Design (SPREAD), designed and developed by the Italian Aerospace Research Centre (CIRA) was used for DMR calculations. Results show low emissions of NO according to the optimized design of the ATR; on the other hand, a tuning of operational conditions is needed for DMR, with its complete re-design to be more conclusive. Analogously, the released amount of water vapour is in good agreement with the required combustion efficiency and the expected propulsive performance.

The purpose of this paper is to present a prospective study of sustainable mobility in the framework of a supporting energy management systems (EMS). Technological advances are still required, namely electric vehicles (EV) endowed with improved EMS in order to increase their performance by making the most of available energy storage technologies. As EVs may be seen as a special domestic load, EMS are proposed based on demand-sensitive pricing strategies such as the Energy Box discussed in this paper.

The study presents an overview of electric mobility and an urban EV project, with special focus on the utilization of its energy sources and their relation with the energy demand of a typical urban driving cycle. Results based on the ECE 15 standard driving cycle for different free market electricity tariffs are presented.

The analysis based on present Portuguese power and energy tariffs reveals that it is highly questionable whether the resulting profit will be enough to justify the potential inconveniences to the vehicle user, as well as those resulting from the increased use of batteries.

The conclusions indicate that more studies on the trade-offs between grid to vehicle and vehicle to grid schemes and electricity pricing mechanisms are needed in order to understand how the utilization of EVs can become more attractive in the end-users’ and utilities’ perspectives.

The paper proposes an approach for future electricity tariff behavior that could be applied to EVs in order to understand whether or not their grid integration in charge and discharge situations would be beneficial for end-users and utilities, in the framework of smart energy management technologies.
