Serious Games: Video Game Design Techniques for Academic and Commercial Communication

Serious Games: Video game design techniques for academic and commercial communication, by Christian Bull-Hansen, Department of Informatics, University of Oslo, Norway. Traditional academic and commercial communication sources, like schools and television, are losing ground to video games. People of all ages spend increasingly more time engaged in virtual worlds and on the Internet, and are becoming used to actively pursuing the information they want to know more about, while rejecting the old passive communication channels where information is presented, but not requested. The result is a generation in need of new ways of informing. This thesis aims to provide ways for academic and commercial communication to exist in commercially popular video games while retaining the entertainment value of the games. Thus making students learn while gaming, as well as provide means for commercial interests to reach the gamer audience. The thesis provides information and analysis of game culture, player-types, social structures, game design techniques, and how knowledge of this information can be used to create and improve academic and commercial communication in video games. The thesis utilizes a custom made prototype, “The Renaissance Prototype”, designed for the purpose of researching and test the theories presented in this thesis

Bilanzierung und Quantifizierung des Chlorbiphenyl-Eintrages in das Oderhaff

Under the EC sponsored research project ODER (Oder Discharge-Environmental Response) first investigations have been carried out to estimate the chlorinated biphenyls (CB) input into Oderhaff via the Oder river. For this purpose, vertical profiles of CB content and composition were analysed on samples of three sediment cores. In two water samples, the content of suspended particulate material as weil as the particulate CB content and congener-specific composition were measured. In the Oderhaff the CB concentrations of particulate material were between 700 to 800 pg/dm3. Significant differences in the composition of the components were not observed. In sediments, CB contents were as high as 17 to 24 ngig dry weight in near surface sediment layers. They decreased with increasing sediment depth and were below detection limits at 15 to 21 cm depth. Based on the size of the 49 accumulation area and related hydrographic conditions, we estimated an input of 95 kg into the Oderhaff for the last 65 years since the onset of CB production. Applying the present prevailing conditions, we calculated an average transport of about 825 kg CB by the Oder river during this period. Comparing these two estimates, we observed that at least 15 % of the CB transported by the Oder river was deposited in the Oderhaff. The remaining 85 % (-730 kg), have been further transported into the South Pomeranian Bight and Southern Baltic Sea

Ikonoklasme

Encyclopedia of Religion (Apostolos-Cappadona 2005:4279), definerer ikonoklasme som intensjonell desekrering eller ødeleggelse av kunst, og særlig den som avbilder mennesket, på bakgrunn av religiøse prinsipper eller tro. Ordet kommer fra det greske eikon, som betyr bilde (ofte et hellig bilde, et ikon), og klasma, som betyr brudd. Begrepet har sitt opphav i den bysantinske bildedebatten, og er historisk nært knyttet til vestlig monoteisme og særlig den bysantinske og proteístantiske billedstorm. Begrepet kan i dag imidlertid også brukes analytisk om bildeødeleggelse generelt, som på ingen måte er et fenomen avgrenset til den kristne eller religiøse sfære

Reversible photoswitching of isolated ionic hemiindigos with visible light

Indigoid chromophores have emerged as versatile molecular photoswitches, offering efficient reversible photoisomerization upon exposure to visible light. Here we report synthesis of a new class of permanently charged hemiindigos (HIs) and characterization of photochemical properties in gas phase and solution. Gas-phase studies, which involve exposing mobility-selected ions in a tandem ion mobility mass spectrometer to tunable wavelength laser radiation, demonstrate that the isolated HI ions are photochromic and can be reversibly photoswitched between Z and E isomers. The Z and E isomers have distinct photoisomerization response spectra with maxima separated by 40–80 nm, consistent with theoretical predictions for their absorption spectra. Solvation of the HI molecules in acetonitrile displaces the absorption bands to lower energy. Together, gas-phase action spectroscopy and solution NMR and UV/Vis absorption spectroscopy represent a powerful approach for studying the intrinsic photochemical properties of HI molecular switches

Galega orientalis – a new persistant plant as fodder crop and substrate for biogas production

In einem langjährig angelegten Anbauversuch soll das jährliche Ertragspotential der ausdauernden Leguminose Galega orientalis (Lam.) in Mecklenburg-Vorpommern ermittelt werden. In den ersten vier Anbaujahren belief sich der jährliche Trockenmasseertrag auf durchschnittlich 100 dt/ha. Die Leguminosenart erwies sich als sehr winterhart. Sie reagierte auf Trockenheit mit verringertem Wachstum, aber ohne die Gefahr des Absterbens. Krankheiten oder Schädlinge wurden nicht beobachtet. Die Pflanzen gelangten sicher zur Samenreife. Im Laborversuch konnte nachgewiesen werden, dass Galega­substrat unter Beachtung der üblichen Silierregeln erfolgreich siliert werden kann. Die durchgeführten Gärversuche im Batch-Betrieb wiesen eine Eignung der Galega für eine Biogasgewinnung nach. Die Ergebnisse belegen, dass Galega unter den natürlichen Bedingungen von Mecklenburg-Vorpommern anbauwürdig ist.    A long-term cultivation trial was established to estimate the agricultural potential of the perennial legume Galega orientalis (Lam.) in Mecklenburg-Western Pomerania. Herbage productivity was monitored for four years. The average annual dry-matter yield of fodder galega was about 10 t ha–1. This legume species was found to be very resistant to frost. Drought induces reduced growth, however there is no danger of dead loss. Diseases or pests were not observed. The plants reliably accomplished seed maturity. Laboratory experiments demonstrated that galega can be ensiled successfully according to the common principles of ensiling. The fermentation batch tests demonstrated the suitability for bio-energy production. Our results indicate that galega is suitable for cultivation under the natural conditions of Mecklenburg-Western Pomerania.   &nbsp

How important is the land use mix measure in understanding walking behaviour? Results from the RESIDE study

<p>Abstract</p> <p>Background</p> <p>Understanding the relationship between urban design and physical activity is a high priority. Different representations of land use diversity may impact the association between neighbourhood design and specific walking behaviours. This study examined different entropy based computations of land use mix (LUM) used in the development of walkability indices (WIs) and their association with walking behaviour.</p> <p>Methods</p> <p>Participants in the RESIDential Environments project (RESIDE) self-reported mins/week of recreational, transport and total walking using the Neighbourhood Physical Activity Questionnaire (n = 1798). Land use categories were incrementally added to test five different LUM models to identify the strongest associations with recreational, transport and total walking. Logistic regression was used to analyse associations between WIs and walking behaviour using three cut points: any (> 0 mins), ≥ 60 mins and ≥ 150 mins walking/week.</p> <p>Results</p> <p>Participants in high (vs. low) walkable neighbourhoods reported up to almost twice the amount of walking, irrespective of the LUM measure used. However, different computations of LUM were found to be relevant for different types and amounts of walking (i.e., > 0, ≥ 60 or ≥ 150 mins/week). Transport walking (≥ 60 mins/week) had the strongest and most significant association (OR = 2.24; 95% CI:1.58-3.18) with the WI when the LUM included 'residential', 'retail', 'office', 'health, welfare and community', <it>and </it>'entertainment, culture and recreation'. However, any (> 0 mins/week) recreational walking was more strongly associated with the WI (OR = 1.36; 95% CI:1.04-1.78) when land use categories included 'public open space', 'sporting infrastructure' and 'primary and rural' land uses. The observed associations were generally stronger for ≥ 60 mins/week compared with > 0 mins/week of transport walking and total walking but this relationship was not seen for recreational walking.</p> <p>Conclusions</p> <p>Varying the combination of land uses in the LUM calculation of WIs affects the strength of relationships with different types (and amounts) of walking. Future research should examine the relationship between walkability and specific types and different amounts of walking. Our results provide an important first step towards developing a context-specific WI that is associated with recreational walking. Inherent problems with administrative data and the use of entropy formulas for the calculation of LUM highlight the need to explore alternative or complimentary measures of the environment.</p

The influence of urban design on neighbourhood walking following residential relocation : longitudinal results from the RESIDE study

The design of urban environments has the potential to enhance the health and well-being of residents by impacting social determinants of health including access to public transport, green space and local amenities. Commencing in 2003, RESIDE is a longitudinal natural experiment examining the impact of urban planning on active living in metropolitan Perth, Western Australia. Participants building homes in new housing developments were surveyed before relocation (n = 1813; 34·6% recruitment rate); and approximately 12 months later (n = 1437). Changes in perceived and objective neighbourhood characteristics associated with walking following relocation were examined, adjusted for changes in demographic, intrapersonal, interpersonal and baseline reasons for residential location choice. Self-reported walking was measured using the Neighbourhood Physical Activity Questionnaire. Following relocation, transport-related walking declined overall (p &lt; 0.001) and recreational walking increased (p &lt; 0.001): access to transport- and recreational destinations changed in similar directions. However, in those with increased access to destinations, transport-related walking increased by 5.8 min/week for each type of transport-related destination that increased (p = 0.045); and recreational walking by 17.6 min/week for each type of recreational destination that increased (p = 0.070). The association between the built environment and recreational walking was partially mediated by changes in perceived neighbourhood attractiveness: when changes in ‘enjoyment’ and ‘attitude’ towards local walking were removed from the multivariate model, recreational walking returned to 20.1 min/week (p = 0.040) for each type of recreational destination that increased. This study provides longitudinal evidence that both transport and recreational-walking behaviours respond to changes in the availability and diversity of local transport- and recreational destinations, and demonstrates the potential of local infrastructure to support health-enhancing behaviours. As neighbourhoods evolve, longer-term follow-up is required to fully capture changes that occur, and the impact on residents. The potential for using policies, incentives and infrastructure levies to enable the early introduction of recreational and transport-related facilities into new housing developments warrants further investigation

The cost of changing physical activity behaviour: Evidence from a "physical activity pathway" in the primary care setting

Copyright @ 2011 Boehler et al.BACKGROUND: The ‘Physical Activity Care Pathway’ (a Pilot for the ‘Let’s Get Moving’ policy) is a systematic approach to integrating physical activity promotion into the primary care setting. It combines several methods reported to support behavioural change, including brief interventions, motivational interviewing, goal setting, providing written resources, and follow-up support. This paper compares costs falling on the UK National Health Service (NHS) of implementing the care pathway using two different recruitment strategies and provides initial insights into the cost of changing physical activity behaviour. METHODS: A combination of a time driven variant of activity based costing, audit data through EMIS and a survey of practice managers provided patient-level cost data for 411 screened individuals. Self reported physical activity data of 70 people completing the care pathway at three month was compared with baseline using a regression based ‘difference in differences’ approach. Deterministic and probabilistic sensitivity analyses in combination with hypothesis testing were used to judge how robust findings are to key assumptions and to assess the uncertainty around estimates of the cost of changing physical activity behaviour. RESULTS: It cost £53 (SD 7.8) per patient completing the PACP in opportunistic centres and £191 (SD 39) at disease register sites. The completer rate was higher in disease register centres (27.3% vs. 16.2%) and the difference in differences in time spent on physical activity was 81.32 (SE 17.16) minutes/week in patients completing the PACP; so that the incremental cost of converting one sedentary adult to an ‘active state’ of 150 minutes of moderate intensity physical activity per week amounts to £ 886.50 in disease register practices, compared to opportunistic screening. CONCLUSIONS: Disease register screening is more costly than opportunistic patient recruitment. However, additional costs come with a higher completion rate and better outcomes in terms of behavioural change in patients completing the care pathway. Further research is needed to rigorously evaluate intervention efficiency and to assess the link between behavioural change and changes in quality adjusted life years (QALYs).This article is available through the Brunel Open Access Publishing Fund
