Locating authenticity in artworks that are remade (all or in part) or re-performed over time presents a unique challenge for art conservators, whose activities have traditionally been oriented toward caring for the material aspects of art objects. The paper offers a brief overview of perspectives on authenticity and discusses various theoretical models that have been developed to conceptualize how media, installation, and performance artworks are displayed and cared for over time. These include the score/performance model, the concepts of autographicity and allographicity, the concept of iteration, and authenticity as a practice. The author proposes a theoretical model based on the ritual aspects of presenting artworks, arguing that authenticity, repetition, and community participation can be reconciled within a ritual context.

AbstractVery/extremely premature infants often experience glycaemic dysregulation, resulting in abnormally elevated (hyperglycaemia) or low (hypoglycaemia) blood glucose (BG) concentrations, due to prematurity, stress, and illness. STAR-GRYPHON is a computerised protocol that utilises a model-based insulin sensitivity parameter to directly tailor therapy for individual patients and their changing conditions, unlike other common insulin protocols in this cohort. From January 2013 to January 2015, 13 patients totalling 16 hyperglycaemic control episodes received insulin under STAR-GRYPHON. A significant improvement in control was achieved in comparison to a retrospective cohort, with a 26% absolute improvement in BG within the targeted range and no hypoglycaemia. This improvement was obtained predominantly due to the reduction of hyperglycaemia (%BG>10.0 mmol/l: 5.6 vs. 17.7%, p<0.001), and lowering of the median per-patient BG [6.9 (6.1–7.9) vs. 7.8 (6.6–9.1) mmol/l, p<0.001, Mann-Witney U test]. While cohort-wide control results show good control overall, there is high intra-patient variability in BG behaviour, resulting in overly conservative treatments for some patients. Patient insulin sensitivity differs between and within patients over time, with some patients having stable insulin sensitivity, while others change rapidly. These results demonstrate the trade-off between safety and performance in a highly variable and fragile cohort.

The issue of the green development of industrial enterprises has become the focus of attention of all parties. However, the driving factors of green development behavior and performance in industrial enterprises remains unexplored. What are the driving factors of green development behavior and performance in industrial enterprises? How does the theoretical model of green development behavior and performance in industrial enterprises work? In order to reveal the driving factors of green development behavior and performance in industrial enterprises, this paper develops a theoretical model and tests the model through the evidence of Chinese industrial enterprises. Based on the further study of in-depth interview materials from 52 employees in industrial enterprises, this paper takes industrial enterprises as the research object and constructs a theoretical model by using a grounded theory method. The results show that 40 initial concepts, 10 initial categories, four main categories and three core categories are obtained through the coding step of grounded theory. The study found the following three conclusions: (1) The green development of industrial enterprise exists in the organization in the form of specific behavioral expressions; (2) The green development of industrial enterprise caused the occurrence of green development behavior of industrial enterprises. The external factors of industrial enterprise green development consist of the environment of policy and institutional, market environment and public supervision. The internal factors of industrial enterprise green development are composed of tangible and intangible resources of enterprises; (3) The occurrence of industrial enterprise green development behavior has led to the consequence of green development of industrial enterprises. The consequence is embodied in the green development performance of industrial enterprises, including corporate financial performance, corporate environmental performance and corporate social performance. In addition, some management implications are presented based on the research findings. This research enriches the field of green development theory, business development theory and green behavior research. This study also provides a reference for exploring theoretical models of industrial enterprise green development in other countries and regions of the world.

The Pavement ME transverse joint faulting model incorporates mechanistic theories that predict development of joint faulting in jointed plain concrete pavements (JPCP). The model is calibrated using the Long-Term Pavement Performance database. However, the Mechanistic-Empirical Pavement Design Guide (MEPDG) encourages transportation agencies, such as state departments of transportation, to perform local calibrations of the faulting model included in Pavement ME. Model calibration is a complicated and effort-intensive process that requires high-quality pavement design and performance data. Pavement management data—which is collected regularly and in large amounts—may present higher variability than is desired for faulting performance model calibration. The MEPDG performance prediction models predict pavement distresses with 50% reliability. JPCP are usually designed for high levels of faulting reliability to reduce likelihood of excessive faulting. For design, improving the faulting reliability model is as important as improving the faulting prediction model. This paper proposes a calibration of the Pavement ME reliability model using pavement management system (PMS) data. It illustrates the proposed approach using PMS data from Pennsylvania Department of Transportation. Results show an increase in accuracy for faulting predictions using the new reliability model with various design characteristics. Moreover, the new reliability model allows design of JPCP considering higher levels of traffic because of the less conservative predictions.

Over Time

Knitted electrodes are a key component to many electronic textiles including sensing devices, such as pressure sensors and heart rate monitors; therefore, it is essential to assess the electrical performance of these knitted electrodes under different mechanical loads to understand their performance during use. The electrical properties of the electrodes could change while deforming, due to an applied load, which could occur in the uniaxial direction (while stretched) or multiaxial direction (while compressed). The properties and performance of the electrodes could also change over time when rubbed against another surface due to the frictional force and generated heat. This work investigates the behavior of a knitted electrode under different loading conditions and after multiple abrasion cycles.

Advances in technology call for a parallel evolution in the software. New techniques are needed to support this dynamism, to track and guide its evolution process. This applies especially in the field of embedded systems, and certainly in Wireless Sensor Networks (WSNs), where hardware platforms and software environments change very quickly. Commonly, operating systems play a key role in the development process of any application. The most used operating system in WSNs is TinyOS, currently at its TinyOS 2.1.2 version. The evolution from TinyOS 1.x and TinyOS 2.x made the applications developed on TinyOS 1.x obsolete. In other words, these applications are not compatible out-of-the-box with TinyOS 2.x and require a porting action. In this paper, we discuss on the porting of embedded system (i.e., Wireless Sensor Networks) applications in response to operating systems’ evolution. In particular, using a model-based approach, we report the porting we did of Agilla, a Mobile-Agent Middleware (MAMW) for WSNs, on TinyOS 2.x, which we refer to as Agilla 2. We also provide a comparative analysis about the characteristics of Agilla 2 versus Agilla. The proposed Agilla 2 is compatible with TinyOS 2.x, has full capabilities and provides new features, as shown by the maintainability and performance measurement presented in this paper. An additional valuable result is the architectural modeling of Agilla and Agilla 2, missing before, which extends its documentation and improves its maintainability.
