A Reusable Scripting Engine for Automating Cinematics and Cut-Scenes in Video Games

Storytelling can play a critical role in the success of modern video games. Unfortunately, it can often be quite difficult for storytellers to directly craft content for games, typically requiring them to work with programmers to implement story elements. This needlessly complicates the development process, straining scarce resources while potentially hampering creativity and story quality at the same time. As a result, supports and tools are necessary to enable storytellers to generate story content for games directly, with minimal programming or programmer assistance required, if any. This paper introduces a Reusable Scripting Engine to automate the generation of cinematics and cut-scenes in video games. This approach allows storytellers to provide their stories in a well-defined, structured format, which is then interpreted by our engine, along with supplemental graphic and audio content, to produce an animated presentation of the story in an automated fashion. This paper presents the design of our Reusable Scripting Engine, and discusses a prototype implementation of this design, as well as initial experiences with using this prototype system to date

Campaigning During COVID-19: How Texas Republicans Navigated the 2020 Election

The COVID-19 pandemic caused major disruptions to political campaigns during the 2020 election. There was a stark contrast between how the two major parties approached campaigning during COVID-19, including the election in Texas, a deep red state that some thought might present opportunities for Democratic Party candidates. Using interviews with 13 campaign operatives, this study examines how Republican candidates in Texas navigated their campaigns in the context of a pandemic. Our results suggest the unique context of campaigning during COVID-19 gave Republicans key advantages over Democrats. Decisions to embrace a more organic, bottom-up approach led to more flexible campaign strategies. Democratic Party candidates followed the lead of Joe Biden’s presidential campaign and mostly refrained from direct voter contact, like door knocking. Through experimentation, many Republican campaigns felt comfortable embracing a ground game and deployed complete field operations. Consultants argued this played an important role in helping Texas Republicans exceed expectations

An in-depth phenomenological study of the effect that knowledge of Human Givens has within executive coaching

This study explores the use of Human Givens ideas within the field of executive coaching. The research was undertaking using a phenomenological approach which sought to understand the lived experience of six executive coaches who had employed some of the Human Givens ideas during their work as executive coaches. Unstructured interviews were conducted and findings suggest overall that the Human Givens ideas could usefully inform coaching practice, but that they should not ultimately define it

Selenate-enriched urea granules are a highly effective fertilizer for selenium biofortification of paddy rice grain

Chittleborough. “Selenate-Enriched Urea Granules Are a Highly Effective Fertilizer for Selenium Biofortification of Paddy Rice Grain.” Journal of Agricultural and Food Chemistry 60, no. 23 (June 13, 2012): 6037–44. https://doi.org/10.1021/jf3005788.We examined the effects of applied selenium (Se) species, time of application, method of application and soil water management regime on accumulation of Se in rice plants. Plants were grown to maturity in a temperature- and humidity-controlled growth chamber using three water management methods: field capacity (FC), submerged until harvest, and submerged and drained two weeks before harvest; two Se species: selenate (SeO[subscript 4] ˉ²) and selenite (SeO[subscript 3]ˉ²) applied at a rate equivalent to 30 g haˉ¹; and four application methods: i) Se applied at soil preparation, ii) Se-enriched urea granules applied to floodwater at heading iii) foliar Se applied at heading and iv) fluid fertilizer Se applied to soil or floodwater at heading. Total Se concentrations in rice grains, husks, leaves, culms and roots were measured, as well as Se speciation in grains from the Se-enriched urea granule treatment. Highest Se concentrations in the grain occurred with SeO[subscript 4] ˉ² and with fertilizer applied at heading stage; SeO[subscript 4]ˉ²-enriched urea granules applied at heading increased grain Se concentrations 5 to 6 fold (by 450-600 μg kgˉ¹) compared to the control (no fertilizer Se applied) in all water treatments. Under paddy conditions other Se fertilization strategies were much less effective. Drainage before harvesting caused Se to accumulate in/on rice roots, possibly through adsorption onto iron plaque on roots. Rice grains contained Se mainly in the organic form as selenomethionine (SeM) which comprised over 90 % of the total grain Se in treatments fertilized with SeO[subscript 4]ˉ² -enriched urea granules. The results of this study clearly show of the fertilizer strategies tested that biofortification of Se in rice grains can best be achieved in lowland rice by broadcast application of SeO[subscript 4]ˉ² -enriched urea granules to floodwater at heading stage

Leaf-applied sodium chloride promotes cadmium accumulation in durum wheat grain

Cadmium (Cd) accumulation in durum wheat grain is a growing concern. Among the factors affecting Cd accumulation in plants, soil chloride (Cl) concentration plays a critical role. The effect of leaf NaCl application on grain Cd was studied in greenhouse-grown durum wheat (Triticum turgidum L. durum, cv. Balcali-2000) by immersing (10 s) intact flag leaves into Cd and/or NaCl-containing solutions for 14 times during heading and dough stages. Immersing flag leaves in solutions containing increasing amount of Cd resulted in substantial increases in grain Cd concentration. Adding NaCl alone or in combination with the Cd-containing immersion solution promoted accumulation of Cd in the grains, by up to 41%. In contrast, Zn concentrations of grains were not affected or even decreased by the NaCl treatments. This is likely due to the effect of Cl complexing Cd and reducing positive charge on the metal ion, an effect that is much smaller for Zn. Charge reduction or removal (CdCl2 0 species) would increase the diffusivity/lipophilicity of Cd and enhance its capability to penetrate the leaf epidermis and across membranes. Of even more significance to human health was the ability of Cl alone to penetrate leaf tissue and mobilize and enhance shoot Cd transfer to grains, yet reducing or not affecting Zn transfer

Bayesian Activity Estimation and Uncertainty Quantification of Spent Nuclear Fuel Using Passive Gamma Emission Tomography

In this paper, we address the problem of activity estimation in passive gamma emission tomography (PGET) of spent nuclear fuel. Two different noise models are considered and compared, namely, the isotropic Gaussian and the Poisson noise models. The problem is formulated within a Bayesian framework as a linear inverse problem and prior distributions are assigned to the unknown model parameters. In particular, a Bernoulli-truncated Gaussian prior model is considered to promote sparse pin configurations. A Markov chain Monte Carlo (MCMC) method, based on a split and augmented Gibbs sampler, is then used to sample the posterior distribution of the unknown parameters. The proposed algorithm is first validated by simulations conducted using synthetic data, generated using the nominal models. We then consider more realistic data simulated using a bespoke simulator, whose forward model is non-linear and not available analytically. In that case, the linear models used are mis-specified and we analyse their robustness for activity estimation. The results demonstrate superior performance of the proposed approach in estimating the pin activities in different assembly patterns, in addition to being able to quantify their uncertainty measures, in comparison with existing methods

Improving the efficacy of selenium fertilizers for wheat biofortification

© 2019, The Author(s). Increasing the selenium (Se) concentration of staple crops by fertilization is a valuable pathway to increase Se in the human diet, thus preventing Se deficiency. A pot trial was set up to investigate whether the application of 3.33 µg kg−1 of Se (equivalent to 10 g ha−1) to wheat can be made more efficient by its co-application with macronutrient carriers, either to the soil or to the leaves. In the soil, Se was applied either on its own (selenate only) or as a granular, Se-enriched macronutrient fertilizer supplying nitrogen, phosphorus, potassium or sulfur. Selenium was also applied to leaves at head emergence with, or without, 2% w/v N fertilizers. With grain Se concentrations varying from 0.13–0.84 mg kg−1, soil application of selenate-only was 2–15 times more effective than granular Se-enriched macronutrient fertilizers in raising grain Se concentrations. Co-application of foliar Se with an N carrier doubled the Se concentration in wheat grains compared to the application of foliar Se on its own, the majority of which was in the highly bioavailable selenomethionine fraction. Results from this study demonstrate the possibility of improving the efficacy of Se fertilizers, which could enrich crops with Se without additional application costs in the field
