title: Return on roller coasters: A model to guide investments in theme park attractions

authors: van Oest, Rutger

subjects: entertainment industry

abstract: Despite the economic significance of the theme park industry and the huge investments needed to set up new attractions, no marketing models exist to guide these investment decisions. This study addresses this gap in the literature by estimating a response model for theme park attendance. The model not only determines the contribution of each attraction to attendance, but also how this contribution is distributed within and across years. The model accommodates saturation effects, which imply that the impact of a new attraction is smaller if similar attractions are already present. It also captures reinforcement effects, meaning that a new attraction may reinforce the drawing power of similar extant attractions, especially when these were introduced recently. The model is calibrated on 25 years of weekly attendance data from the Efteling, a leading European theme park. Our return on investment calculations show that it is more profitable to invest in multiple smaller attractions than in one big one. This finding is in remarkable contrast with the current "arms race" in the industry. Furthermore, even though thrill rides tend to be more effective than theme rides, there are conditions under which one should consider to switch to the latter.

title: Drawing diagrams in TEX documents

authors: Rogers, Bill

abstract: The typesetting language TEX [Knuth (1984)] is now available on a range of computers from mainframes to micros. It has an unequalled ability to typeset mathematical text, with its many formatting features and fonts. TEX has facilities for drawing diagrams using the packages tpic and PiCTEX. This paper describes a TEX preprocessor written in Pascal which allows a programmer to embed diagrams in TEX documents. These diagrams may involve straight or curved lines and labelling text. The package is provided for people who either do not have access to tpic or PiCTEX or who prefer to program in Pascal.

title: My responsibility in the face of mass extinction

authors: Gray-Sharp, Katarina

subjects: autoethnography

abstract: Extinction is the “irreversible condition of a species or other group of organisms having no living representatives in the wild, which follows the death of the last surviving individual of that species or group” (Hine and Martin 2015g, para. 1). Mass extinctions are extinctions of the greatest magnitude, occurring “when many diverse groups of organisms become extinct over short periods of time” (Condie 2011, 250). These “are not step-events but rather a step into a prolonged alternative global ecosystem state” (Hull 2015, R941). Five mass extinctions have previously been recorded. A sixth has begun. Humans are the cause of the latest episode.

This thesis develops an Indigenous, non-agential conception of responsibility for considering an ethical problem of wide consequence. Founded in mātauranga Māori and recalling the work of Emmanuel Levinas, it applies Kaupapa Māori autoethnography, narrative, and conceptual analyses alongside exegeses and a replication study. Investigations of responsibility across various positions are encountered: those found in place and polity, those made as visitor and the commanded, those gifted as inherited erudition and in the suffering-with. Now facing the last structural violence, what is my responsibility?
