title: Hospitality crisis management practices: The case of Indian luxury hotels

authors: Israeli, Aviad A.

subjects: hospitality

abstract: This study examines hospitality crisis management practices within the context of the Indian hospitality industry. The study is a replication of a study previously conducted in Israel. The study employs a questionnaire that evaluates the importance and usage of four themes of practices: marketing, hotel maintenance, human resources and governmental assistance. The findings illustrate which practices managers consider important and which practices managers actually use during a crisis. The paper concludes with recommendations for future research and management of crises.

title: Aerodynamics of two-dimensional sail wings

authors: Bundock, Michael Stephen

subjects: Aerodynamics

abstract: The purpose of this work is to obtain the exact solution for the profile and characteristics of a two-dimensional sail, immersed in an inviscid incompressible fluid. An experimental investigation was also performed and results are compared with theoretical predictions. 

The sail was assumed to be an infinitely flexible, non-porous membrane of zero thickness, fixed at the leading and trailing edges, and stretched under a constant tension T in the sail surface. An aerofoil model was considered where the airflow remains smoothly attached over the entire profile. 

All known previous studies have also used the inviscid fluid approximation, but made the further assumptions of small angle of attack and negligible profile slopes. These assumptions enable the use of thin aerofoil theory predictions for pressure distribution and linearisation of the sail equation.

In contrast this investigation obtains the exact solution. An iterative numerical method is devised whereby an initial estimate is made for the profile using thin aerofoil theory. The pressure distribution is then determined using Theodorsen's method and the profile recalculated using the full sail equation, so that tension and pressure forces are balanced. The cycle of redetermining the pressure distribution and profile is repeated until a convergent solution is obtained.

Results are shown for the profile, lift coefficient and centre of pressure, for various angles of attack and states of tension. For sails with non-negligible camber, values of lift coefficient and centre of pressure are found to differ significantly from those predicted by the linear approximations. Previous researchers have established the existence of a critical tension state where the tension force is unable to contain the pressure forces acting on the sail, and predicted that the value of this state (KTc) was independent of angle of attack. However this study indicates that KTc increases with increasing angle of attack. Centre of pressure calculations, for various angles of attack and states of tension, indicate that two-dimensional sails may possess either static longitudinal stability or instability, depending on the tension state. Experimental results for the profile, KTc, lift coefficient and centre of pressure are compared with theory, and areas of agreement and disagreement discussed. Experimental values for the drag coefficient and the lift to drag ratio were obtained and are discussed in detail.

title: Māori and Pacific traditional caregiving practices: Voices from the community

authors: Glasgow, Ali

abstract: Increasing numbers of Māori and Pacific infants are enrolled in early childhood services in Aotearoa/New Zealand. This phenomenon is part of a larger societal trend in which mother return to the workforce within months of their infant’s birth. This development has significant impacts on early childhood service provision, particularly in relation to addressing the cultural needs of infants. A major concern is that Māori and Pacific infants are at risk of cultural deprivation within these services. According to the research reported in this chapter, there is a call within Māori and Pacific communities for Māori and Pacific infants to be raised in culturally responsive ways in early childhood services children’s home language, culture and identity are promoted and maintained. In Aotearoa/ New Zelanad, infant caregiving theory is largely based on Western European theory and principles that promote individualism and independence, and this will be elaborated upon in the chapter. This chapter outlines findings from a nationwide Aotearoa/ New Zealand online survey conducted with Māori and Polynesian Pacific “language nest” teachers on traditional cultural practices for Māori and Polynesian infants. The language nest philosophies and programmes promote culture, language and traditional practices. Respondents expressed the desire for autonomy in providing culturally authentic caregiving practices, and frustration with educational theory and government policies that did not align, or ran contrary to, modern cultural practice. Research findings revealed Māori and Polynesian Pacific traditional cultural values, beliefs and practices, and from this common base is an emerging Polynesian theoretical model of infant caregiving practices. It is anticipated that a Polynesian theory of infant caregiving will guide Aotearoa/ New Zealand’s early childhood education services and government policy, ensuring culturally responsive practices for Māori and Polynesian Pacific infants and their families.
