How to Define Games and Why We Need to
2019
This article provides guidelines on how to make useful game definitions and discusses when that is a worthwhile undertaking. It examines a recent article attempting to define videogames (Bergonse in Comput Games J 6(4):239–255, 2017. https://doi.org/10.1007/s40869-017-0045-4), and uses it as an example to discuss game definitions in general. It concludes with reasons why making a final definition of games is not possible and why we need to continue to define games. peerReviewed
Differences in Immaterial Details: Dimensional Conversion and Its Implications for Protecting Digital Designs Under EU Design Law
2021
AbstractThe paper considers three main questions: the legal status of digital designs from the perspective of EU design law, whether the protection is tied to the reproduction of physical products, and whether the scope of protection covers dimensional conversion such as using a 3D design in 2D form or vice versa. There are two sets of views regarding dimensional conversion: the “abstract” and the “concrete” view. These two different attitudes towards the scope of protection influence the manner in which the protectability of digital designs is assessed. In the “abstract” protection, it would not matter whether a product only exists as a digital image and not as a physical shape. In the “co…
The Rotary Aero Engine from 1908 to 1918
2012
The rotary aero engine is a special type of air-cooled radial engine, where the cylinders are arranged like the spokes of a wheel and turn around the crankshaft. The propeller is connected to the cylinders, while the crankshaft is fixed to the frame. The rotary aero engine, developed in 1908, set new standards of power and light weight within the aircraft industry. It was adopted by many pioneer aviators and widely used to set records of endurance, speed and height. Many aero engine manufacturers produced different models and variants of this type of engine, which was extensively used until the end of the First World War. The latest evolution of the rotary engine was the counter-rotary arra…
Decacyclene as complexation manifold: synthesis, structure and properties of its Fe2 and Fe4 slipped triple-decker complexes.
2006
Reaction of [(eta(5)-Me4EtC5)Fe(II)Cl(tmeda)] (tmeda = N,N,N'N'-tetramethylethylenediamine) with a polyanion solution of decacyclene (1) results in the formation of the triple-deckers [{(eta(5)-Me4EtC5)Fe}2-mu2-(eta(6):eta(6)-decacyclene)] (3) and [{(eta(5)-Me4EtC5)Fe}4-mu4-(eta(6):eta(6):eta(6):eta(6)-decacyclene)] (4). Metal complexation in 3 and 4 occurs on opposite faces of the pi perimeter in an alternating mode. The decacyclene ring adopts a gently twisted molecular propeller geometry with twofold crystallographic symmetry (C2). Complex 4 crystallizes in the chiral space group C222(1); the investigated crystal only contains decacyclene rings with M chirality. The handedness can be ass…
Establishing Video Game Genres Using Data-Driven Modeling and Product Databases
2015
Establishing genres is the first step toward analyzing games and how the genre landscape evolves over the years. We use data-driven modeling that distils genres from textual descriptions of a large collection of games. We analyze the evolution of game genres from 1979 till 2010. Our results indicate that until 1990, there have been many genres competing for dominance, but thereafter sport-racing, strategy, and action have become the most prevalent genres. Moreover, we find that games vary to a great extent as to whether they belong mostly to one genre or to a combination of several genres. We also compare the results of our data-driven model with two product databases, Metacritic and Mobyga…
“Cute Goddess is Actually an Aunty”: The Evasive Middle-Aged Woman Streamer and Normative Performances of Femininity in Video Game Streaming
2022
In this paper the focus is on the representations of “middle-aged” or “aging” women streamers in western media. I analyze discussions in Western online media around a case of Chinese DouYu live-streamer. “Qiaobiluo Dianxia,” as her streamer name goes, became a topic in Western media after a glitch in her live stream revealed her to be a middle-aged woman, rather than young woman she was assumed to be. The discussions are analyzed with critical discourse analysis. It is argued that the aging bodies of women, both their presence and absence, should be read and understood through toxic gaming culture and geek masculinity and the hegemonic discourse they constitute.
Associations between Sports Videogames and Physical Activity in Children
2022
Abstract Objective: The aim of the study was to examine the associations of sports video gaming behaviour in the sociological concept of Physical Activity Relationships (PAR) and to see if sports video gaming differs by gender. Methods: A convenience sample of children between 11–12 years of age (n = 114) from three Finnish regions completed a questionnaire on perceptions of their video gaming and physical activity habits. Differences by gender were tested by contingency tables, and blockwise binary logistic regressions were used to examine the strength of association with physical activity behaviour in PAR. Results: Almost all girls had low importance to video gaming and over two thirds (7…
Sapropel as a Binder: Properties and Application Possibilities for Composite Materials
2015
Recent development trends largely look for possibilities of a wider use of natural materials and local resources. In this perspective, the use of organic rich lake sediment - sapropel - as a binding material in line with other environmentally friendly filling materials can be considered as a challenge. Sapropel itself is a valuable resource with multiple areas of application, for example, medicine, veterinary, agriculture, livestock farming, balneology, cosmetic applications, construction, and its application options have been widely studied in the 20th century in the Baltic countries, Ukraine and Russia. Birch wood fibre and sanding dust, hemp shives, 'Aerosil' are used as a filler and thr…
Reventilation Episodes During the Sapropel S1 Deposition in the Eastern Mediterranean Based on Holococcolith Preservation
2019
Organic-rich layers (sapropels), preserved in eastern Mediterranean marine sediment records, represent pronounced perturbations to thermohaline circulation and environmental conditions in the basin, in response to enhanced African monsoon activity and subsequent massive freshwater discharge. During the most recent event, Sapropel S1 formed between 10.8 and 6.1 ka, when freshwater-driven stratification caused seafloor anoxia below ~1,800-m depth, as a result of both failure of deep water formation and enhanced productivity. Here we analyze coccolith assemblages from the open eastern Mediterranean that form a west-east transect across the basin and provide insights on past environmental chang…
