Countries: Deciding on an Offshore Location
Published in Johann Rost, The Insider’s Guide to Outsourcing Risks and Rewards, 2016
Do not think that land in emerging countries is necessarily cheap: in 2006 a construction site in a good position in Bucharest, Romania cost more than $2000 per square meter. The price for a five-star hotel ranged beyond $200 per night.
Do Electronic Word-of-Mouth and Elaboration Likelihood Model Influence Hotel Booking?

It is widely stated in psychology literature that a person’s demographic may predict human behavior [17]. By using chi-square test, Qi et al. [68] discovered substantial differences between on-line and off-online five-star hotel booking in terms of age, gender, education and income. However, Qi et al. [68] did not examine the effects of the demographic profile on booking intention. Therefore, in this study we would like to include age, gender, education and monthly income as the possible predictors. We anticipate that there will be differences due to disparities in gender, age, monthly income and education level. Hotel patrons who are older may have less booking intention compared to the younger ones who are more IT savvy. Besides that, there may also be gender differences as females may have higher booking intention than males since they are the ones who are in charge of planning for accommodation most of the time. With higher level in education, we expect that the tendency to have high propensity in online hotel booking to be greater as it may need more IT skills. Last but not the least, there is great possibility that consumers from higher monthly income will be more inclined to book hotel online compared to those from lower income. Therefore, with the above justifications, we proposed the subsequent research model (Figure 3).
Quantifying the nationwide HVAC energy savings in large hotels: the role of occupant-centric controls

Carle (2014) conducted a case study to instigate the energy savings of HVAC OCC for hotel guestrooms in a five-star hotel in the Middle East. The actual energy use and costs of two rooms, of which one had standalone occupant-centric controls and the other did not, showed that the occupancy presence sensor could bring an energy-saving ratio of 35%. The calculated Return on Investment (ROI) was about 3.5 years, and the Internal Rate of Return (IRR) over six years was 18.9%.

To extend the availability of outdoor swimming pools in the winter, advanced heating systems have been developed. One popular way is to use solar collectors. For instance, Yadav and Tiwari (1987) analysed the performance of a heating system using solar collectors with heat exchangers. It was concluded that increasing the water flowrate and solar collector area could increase the water temperature. Rakopoulos and Vazeos (1987) used experimental data to validate the reliability of an analytical model of a heating system using solar collectors. A similar study was conducted by Haaf, Luboschik, and Tesche (1994). Molineaux, Lachal, and Guisan (1994a) conducted a performance analysis of a system with solar collectors for heating five different swimming pools in Switzerland. The experimental study in research by Croy and Peuser (1994) indicated that a heating system with solar collectors had a better economic performance than a conventional heating system. Dang (1986) concluded that the energy efficiency of solar collectors could reach up to 53.3% when they were used in a swimming pool in India. Another popular method is to use heat pumps. For instance, Greyvenstein and Meyer (1991) concluded that using heat pumps might be more economically beneficial than using solar collectors because the initial cost of heat pumps may be lower than that of solar collectors. Lam and Chan (2001, 2003) used heat pumps to provide heat for a five-star hotel in Hong Kong and concluded that the energy performance of the system was considerable in comparison with that of conventional heating systems. Waste-heat-recovery technologies have also been developed to heat outdoor swimming pools. For instance, Borge et al. (2011) concluded that using the waste heat from air-conditioning systems could not only reduce a swimming pool’s heating demand, but also improve the energy efficiency of the air-conditioning systems. Harrington and Modera (2013) found that the energy consumption of an air-conditioning system could be reduced by 25% to 30% when its waste heat was provided to a swimming pool. Geothermal energy technologies have been developed to heat outdoor swimming pools as well. For instance, Somwanshi, Tiwari, and Sodha (2013) presented a simulation study to analyse the performance of a system using geothermal plants and they found that the pool water temperature could be maintained between 22°C and 27°C when the proposed system was used. Some scholars have investigated using biomass boilers to heat outdoor swimming pools. Katsaprakakis (2015) concluded that the operating costs of a system could be effectively reduced when the proposed system with biomass boilers was used.
