Value Network Dynamics in 3G-4G Wireless Communications: a System Thinking approach to the Strategic Value Assessment Model
No full textThis article develops a map to analyze the dynamic forces that influence the structure and development of 3G (third generation) wireless communications value networks. The analysis builds on the Strategic Value Assessment Model (Fine, et al. 2002) and
utilizes a qualitative System Dynamics mapping approach. The map focuses on the driving forces affecting user adoption of 3G services, focusing on customer dynamics, competitive dynamics, and technology dynamics. To analyze adoption of 3G services by customers, the articles maps the dynamics of (1) network investment and user population, (2) entry of service innovators as well as price competitors, (3) the effects of positive network externalities arising from a larger user population, (4) price compression as lower willingness-to-pay users adopt 3G services, (5) scale economies in terminal costs and prices, and (6) new content development as a draw to new users. Applying inductive systems diagrams hypotheses are integrated into a causal loop map and tested with data collected at 15 communications-industry workshops attended by 190 participants in Europe. The map aims to deepen the understanding of the possible evolutionary paths of the 3G wireless value network. The article seeks also to assess which future scenarios are plausible and what dynamic triggers might make them likely

Measurement of spatial and temporal fine sediment dynamics in a small river
No full textEmpirical measurements on fine sediment dynamics and fine sediment infiltration and accumulation have been conducted worldwide, but it is difficult to compare the results because the applied methods differ widely. We compared common methods to capture temporal and spatial dynamics of suspended sediment (SS), fine sediment infiltration and accumulation and tested them for their suitability in a small, canalized river of the Swiss Plateau. Measurement suitability was assessed by data comparison, relation to hydrological data and in the context of previously published data. SS concentration and load were assessed by optical backscatter (OBS) sensors and SS samplers. The former exhibit a better temporal resolution, but were associated with calibration problems. Due to the relatively low cost and easy mounting of SS samplers, they can provide a higher spatial distribution in the river’s cross section. The latter resulted in a better correlation between sediment infiltration and SS load assessed by SS samplers than SS concentrations measured with OBS sensors. Sediment infiltration baskets and bed loadtraps capture the temporal and spatial distribution of fine sediment infiltration. Data obtained by both methods were positively correlated with water level and SS. In contrast, accumulation baskets do not assess the temporal behaviour offine sediment, but the net accumulation over a certain time period. Less fine sediment accumulated in upwelling zonesand within areas of higher mean water level due to scouring of fine sediments. Even though SS and sediment infiltration assessed with the bedload traps increased from up- to downstream, less fine sediment accumulated downstream. This is probably also attributable to more scouring downstream

God, Fine-Tuning, and the Problem of Old Evidence
No full textThe fundamental constants that are involved in the laws of physics which describe our universe are finely-tuned for life, in the sense that if some of the constants had slightly different values life could not exist. Some people hold that this provides evidence for the existence of God. I will present a probabilistic version of this fine-tuning argument which is stronger than all other versions in the literature. Nevertheless, I will show that one can have reasonable opinions such that the fine-tuning argument doesn’t lead to an increase in one’s probability for the existence of God

Western attraction: theming the postcolonial dark ride
No full textThis project involves the conceptualization, design, construction and staging of -tzintlán, the world’s first postcolonial theme park. This support paper provides a broad understanding of the core concepts, theories, material considerations and historical background for the project. The paper hybridizes academic writing forms with second-person narrative, itself an immersive experience that transforms the paper into a ride. In this way the paper reflects its own content, demonstrating how story, narrative and thought are embodied, affective, sensory, and somatic experiences. This approach allows for a critical examination of theming, immersive technologies, and multi-layered spaces, for the purpose of developing decolonial, Indigenous/Chicanx futurist strategies for worldbuilding and self-conceptualizing. The paper addresses -tzintlán as a space-maker for the exhibiting of site-specific works, a blend between artistic and curatorial practice. The paper guides the reader through questions of fidelity, time, ephemeral, liminal, inverted, and subverted spaces as they pertain to the construction of -tzintlán. Attention is given to major influences on the thinking behind the park, including Disneyland and Aztlán, two multilayered territories which have shaped the artist’s own worldviews, imaginaries, and cultural spheres. It also provides examples of other art-centered carnivals and theme parks which have influenced -tzintlán. Details on the process of designing and creating -tzintlán are given, along with information on each component within the park.
