The purpose of this chapter is to provide a baseline understanding of the scope of youth employment in tourism and hospitality. The chapter begins by defining youth employment in tourism and hospitality. Following the provision of the commonly accepted statistical definition of youth as it applies to labour markets, attention turns to the concept of youth employment whereby it will become apparent that what counts as youth employment will depend on societal context. The chapter then returns to the measurement of tourism employment and some of the difficulties associated with this, which have implications for understanding youth employment in the sector. Key statistics relating to youth employment in tourism and hospitality are then presented and discussed, drawing on governmental and non-governmental data.

The Taguchi robust design concept is combined with the multi-objective deterministic optimization method to overcome single point design problems in Aerodynamics. Starting from a statistical definition of stability, the method finds, Nash equilibrium solutions for performance and its stability simultaneously.

Abstract A major hurricane [96+ knots (kt; 1 kt = 0.51 m s–1) of maximum sustained wind] has not made landfall in the United States since Wilma (2005). Recent elegant stochastic–statistical modeling estimates the return period of a 9-yr streak for this metric as 177 yr, suggesting extraordinary rarity, especially in the context of the length of the record (1851–2014). Current awareness of the drought is increased given that the 2015 hurricane season is expected to be suppressed from El Niño and the recent anniversaries of several noteworthy landfalls. Yet, here we show that the significance or even existence of the current 9-yr drought is highly dependent on the metric used. Acknowledging that wind intensity estimates are binned every 5 kt and have approximate 10-kt uncertainty, we examine the same record using landfall thresholds of 95–105 kt. Using 105-kt landfall, 1993–2003 becomes a previously unreported yet more remarkable 11-yr drought and 1981–88 becomes an 8-yr drought. Further, landfall minimum sea level pressure is more reliably estimated than maximum sustained wind speed. For landfall intensities stronger than 960 hPa (a climatological threshold for 100 kt), the current drought disappears because of Irene (2011) and Sandy (2012). A coastline-independent yet nearby proximity metric is tested and reveals a nonexistent drought. Accordingly, this study suggests the following: 1) Caution is advised when identifying a hurricane drought and its historical significance. 2) Using hurricane landfall statistics to infer a climate signal is fraught with issues (threshold, coastline, and potentially nonscientific contributions), regardless of intensity metric. 3) From a societal context, human and financial losses matter most, and Irene [2011; $8 billion (U.S. dollars)] and Sandy (2012; $88 billion) occurred during the current drought.

Independent Behavior

Human habits are considered to be an important root of societal problems. The significance of habits has been demonstrated for a variety of behaviors in different domains, such as work, transportation, health, and ecology, suggesting that habits have a pervasive impact on human life. Studying and changing habits in societal context requires a broad view of behavior, which poses a challenge for applying basic models to complex human habits. We address the conceptualization and operationalization of habits in the current literature and note that claims about the role of habits in societal context rarely agree with the basic definition of habits as goal-independent behavior. We consider future directions that are important for making progress in the study of habit change in societal context.
