    We present a pilot study investigating the use of mobile technology to augment live performance dance. An augmented performance was created and viewed through an tablet device then analysed from a technical and audience standpoint. Low complexity augmentations were found to be very effective, however the device placed restrictions on higher complexity augmentations, the performance length and the stage/audience spatial arrangements. A low-number audience test indicated that augmentation of live performance was a credible concept, though there are some clear challenges to be overcome specifically around speed of technology and weight of device

    Stoichiometric regulation in micro- and mesozooplankton

    Aquatic ecosystems experience large natural variation in elemental composition of carbon (C), nitrogen (N) and phosphorus (P), which is further enhanced by human activities. Primary producers typically reflect the nutrient ratios of their resource, whose stoichiometric composition can vary widely in conformity to environmental conditions. In contrast, C to nutrient ratios in consumers are largely constrained within a narrow range, termed homeostasis. In comparison to crustacean zooplankton, less is known about the ability of protozoan grazers and rotifer species to maintain stoichiometric balance. In this study, we used laboratory experiments with a primary producer (Nannochloropsis sp.), three different species of protozoan grazers and one mesozooplankton species: two heterotrophic dinoflagellates (Gyrodinium dominans and Oxyrrhis marina), a ciliate (Euplotes sp.) and a rotifer (Brachionus plicatilis) to test the stoichiometric response to five nutrient treatments. We showed that the dependency of zooplankton C:N:P ratios on C: nutrient ratios of their food source varies among species. Similar to the photoautotroph, the two heterotrophic dinoflagellates weakly regulated their internal stoichiometry. In contrast, the strength of stoichiometric regulation increased to strict homeostasis in both the ciliate and the rotifer, similar to crustacean zooplankton. Our study further shows that ciliate and rotifer growth can be constrained by imbalanced resource supply. It also indicates that these key primary consumers have the potential to trophically upgrade poor stoichiometric autotrophic food quality for higher trophic levels

    Understanding dynamics on ultrafast timescales enables unique and new insights into important processes in the materials and life sciences. In this respect, the fundamental pump-probe approach based on ultra-short photon pulses aims at the creation of stroboscopic movies. Performing such experiments at one of the many recently established accelerator-based 4th-generation light sources such as free-electron lasers or superradiant THz sources allows an enormous widening of the accessible parameter space for the excitation and/or probing light pulses. Compared to table-top devices, critical issues of this type of experiment are fluctuations of the timing between the accelerator and external laser systems and intensity instabilities of the accelerator-based photon sources. Existing solutions have so far been only demonstrated at low repetition rates and/or achieved a limited dynamic range in comparison to table-top experiments, while the 4th generation of accelerator-based light sources is based on superconducting radio-frequency technology, which enables operation at MHz or even GHz repetition rates. In this article, we present the successful demonstration of ultra-fast accelerator-laser pump-probe experiments performed at an unprecedentedly high repetition rate in the few- hundred-kHz regime and with a currently achievable optimal time resolution of 13 fs (rms). Our scheme, based on the pulse-resolved detection of multiple beam parameters relevant for the experiment, allows us to achieve an excellent sensitivity in real-world ultra-fast experiments, as demonstrated for the example of THz-field-driven coherent spin precession

    This initial stage paper focuses on the Virtual Reality (VR) experience of the [pain]Byte ballet. The live and VR experience debut October 1st 2017, as part of the Brighton digital festival. Specifically, the development of the VR environment to compliment live performance by using the same choreography to create an option capture element of the VR story telling experience. Reviewing Virtual & Alternative reality gaming & storytelling works and the use of VR for chronic pain management (Chen, Win). Does the VR experience compare to that of the live theatre for the audience? The data visualisations and VR environment will be continuations of the Network Simulator, [data]Storm 2015. We are visualising and comparing the pain pathway system to that of a social network. Linking pain signals to viral/negative messaging for some of the visuals. The main purpose of the pieces links to how “we" present ourselves online, these better or veiled versions of ourselves. For chronic pain sufferers, this can be daily activity in the real world. The paper concludes by identifying some future directions for the research project. The Ballet: [pain]Byte is a data driven dance classical ballet performance and VR (virtual reality) experience. [pain]Byte, is about chronic pain and biomedical engineering, in particular the use of implanted technology - neuromodulation (Al-Kaisey et al). Using data as a medium for storytelling, what it means to be in chronic pain. The live augmented theatre and VR experience research focuses on how an audience’s exposure and understanding are impacted by the difference mediums used for [pain]byte

    Translation and Psychometric Testing of the Hägerbäumer Presenteeism Scale in English

    Purpose Interest in presenteeism has increased in research. Presenteeism is a behaviour of going to work despite illness. It has been predominantly measured using single items, which introduce limitations to validity. To overcome these limitations, Hägerbäumer developed a German multi item presenteeism scale. Methods The aim of the study was to provide an English translation and psychometric testing of the scale. This was conducted in two phases with native English-speaking employed adults. Phase 1 includes translation and cognitive debriefing, phase 2 testing construct validity and internal consistency reliability. Results Cognitive debriefing with 10 employees revealed no problems with understanding or answering the translated items. In total, 487 employed adults participated in the study, of which data from 287 were included in the analysis. For structural validity, the goodness-of-fit indicators all reached their thresholds (TLI = 0.98, CFI = 0.99, RMSEA = 0.07, SRMR = 0.02). The scale does not show differences between sexes and age groups but between sectors (F6,70.95 = 5.53, p < 0.001). The internal consistency reliability was satisfactory with α = 0.89 (CI 95%, 0.87–0.91). Conclusion The translated multidimensional scale for measuring presenteeism at the behavioural level demonstrated good psychometric properties in an initial validation. Further psychometric testing is required before using this scale in cross-national comparison in research and international companies

    Формирование городской идентичности как способ развития туристского потенциала г.Томска

    Следствием глобализации становится унификация современных городов. Происходит нивелирование их уникальных черт: их культурной, социальной и визуальной идентичности. Процесс постепенной утраты уникальности и традиций города неизбежно влечет за собой снижение его привлекательности для туристов. Город, без ярко выраженного "лица": узнаваемого визуального образа и устойчивых смысловых ассоциаций, неизбежно, сдает свои позиции на современном высоко конкурентном рынке туристских услуг.The consequence of globalization is the unification of modern cities. There is a leveling of their unique features: their cultural, social and visual identity. The process of gradual loss of uniqueness and traditions. The city, without a pronounced "face": a recognizable visual image and stable semantic associations, inevitably, surrenders its positions in the modern highly competitive market of tourist services

    Combining GAL4 GFP enhancer trap with split luciferase to measure spatiotemporal promoter activity in Arabidopsis.

    In multicellular organisms different types of tissues have distinct gene expression profiles associated with specific function or structure of the cell. Quantification of gene expression in whole organs or whole organisms can give misleading information about levels or dynamics of expression in specific cell types. Tissue- or cell-specific analysis of gene expression has potential to enhance our understanding of gene regulation and interactions of cell signalling networks. The Arabidopsis circadian oscillator is a gene network which orchestrates rhythmic expression across the day/night cycle. There is heterogeneity between cell and tissue types of the composition and behaviour of the oscillator. In order to better understand the spatial and temporal patterns of gene expression, flexible tools are required. By combining a Gateway®-compatible split luciferase construct with a GAL4 GFP enhancer trap system, we describe a tissue-specific split luciferase assay for non-invasive detection of spatiotemporal gene expression in Arabidopsis. We demonstrate the utility of this enhancer trap-compatible split luciferase assay (ETSLA) system to investigate tissue-specific dynamics of circadian gene expression. We confirm spatial heterogeneity of circadian gene expression in Arabidopsis leaves and describe the resources available to investigate any gene of interest
