From the early days of slag metal reaction studies in the 1950?s to the mid 1980s, a generation of metallurgists contributed much to the theory of slags and their reactions. These workers showed us the importance of charge transfer in slags. They demonstrated that the reaction interface could change dramatically under the influence of reaction and many questions were asked about the specific reaction mechanisms. This paper will review work in slag metal reactions since the mid 1980s and examine our progress in answering some of the questions raised by the early pioneers. The author will focus on recent work from his own laboratory as well as labs from around the World. Finally the author will make some suggestions regarding future directions in this field.

Within English language teaching (ELT), critical scholarship has paid ever-increasing attention to identity, experience and (in)equity, and thus to privilege-marginalization: where it comes from, how and why it manifests, who (potentially) experiences it, and what might be done to address inequity in (and potentially beyond) the profession. This dialogue is intertwined with broader attempts in the field to account for the complexity of identity and interaction in settings around the globe. In this article, I discuss how categorical apprehensions of identity, experience and privilege-marginalization, and approaches to (in)equity, have framed discourse within critical scholarship. I then survey how more recent work has called into question many of the critical “assumptions” (Pennycook, 2001) both shaping and shaped by such theory and inquiry. This scholarship contends that critical lenses predicated upon categories of being, while calling attention to idealized nativeness embedded in ELT, fail to account for the contextualized, sociohistorical negotiation of privilege-marginalization within and transcending communities around the globe. Next, in order to contextualize and unpack these divergent lenses, I provide a review of critical dialogue attending to Japan, both in and beyond ELT, noting in conclusion how privilege-marginalization within ELT is intertwined with the sociohistorical negotiation of “selfhood” and “otherness” pertaining both to Japanese society and Japan and “the world beyond.” I close by briefly commenting on future directions for critical scholarship in ELT, and the challenges facing, and yet to be faced by, its stakeholders.

The international dimension of science and engineering education is of paramount importance and merits serious consideration of the coherent skill set that is required to allow scientists and engineers more readily to transport themselves and their work to other locations in the world.

Wellbeing science is the scientific investigation of wellbeing, its’ antecedents and consequences. Alongside growth of wellbeing science is significant interest in wellbeing interventions at individual, organizational and population levels, including measurement of national accounts of wellbeing. In this concept paper, we propose the capability model of wellbeing literacy as a new model for wellbeing science and practice. Wellbeing literacy is defined as a capability to comprehend and compose wellbeing language, across contexts, with the intention of using such language to maintain or improve the wellbeing of oneself, others or the world. Wellbeing literacy is underpinned by a capability model (i.e., what someone is able to be and do), and is based on constructivist (i.e., language shapes reality) and contextualist (i.e., words have different meanings in different contexts) epistemologies. The proposed capability model of wellbeing literacy adds to wellbeing science by providing a tangible way to assess mechanisms learned from wellbeing interventions. Moreover, it provides a framework for practitioners to understand and plan wellbeing communications. Workplaces and families as examples are discussed as relevant contexts for application of wellbeing literacy, and future directions for wellbeing literacy research are outlined.

In their editorial for the first issue of Tourist Studies, Adrian Franklin and Mike Crang made us aware that tourism research had shifted to an exploration of the extraordinary everyday where ‘more or less everyone now lives in a world rendered or reconfigured as interesting, entertaining and attractive – for tourists’. From our standpoint 20 years later, we suggest this particular departure point has important insights to offer our understanding of a quintessential tourism event, that of the festival, which now intervenes in daily life in all manner of ways. In this commentary, we present a reflective commentary on recent scholarship that advocates for more rigour in festival studies, with greater theory development and testing within the festival context, and how this work is suggestive of future directions for festival research. We present several areas that are ripe for further research, particularly given the tumultuous nature of the world we are living in, such as the challenges of climate change and how we might socialise in a post-Covid world. Much has changed in the 20 years since the inception of Tourist Studies, but festivals remain resilient – they will re-emerge in future, perhaps not unscathed but with a renewed sense of purpose.

Analysis Quality

Understanding program behaviors is important to verify program properties or to optimize programs. Static analysis is a widely used technique to approximate program behaviors via abstract interpretation. To evaluate the quality of static analysis, researchers have used three metrics: performance, precision, and soundness. The static analysis quality depends on the analysis techniques used, but the best combination of such techniques may be different for different programs. To find the best combination of analysis techniques for specific programs, recent work has proposed parametric static analysis . It considers static analysis as black-box parameterized by analysis parameters , which are techniques that may be configured without analysis details. We formally define the parametric static analysis, and we survey analysis parameters and their parameter selection in the literature. We also discuss open challenges and future directions of the parametric static analysis.

В статье рассмотрен вопрос идентифицируемости математической модели кинетики химической реакции. В процессе решения обратной задачи по оценке параметров модели, характеризующих процесс, нередко возникает вопрос неединственности решения. На примере конкретной реакции продемонстрирована необходимость проводить анализ идентифицируемости модели перед проведением численных расчетов по определению параметров модели химической реакции. The identifiability of the mathematical model of the kinetics of a chemical reaction is investigated in the article. In the process of solving the inverse problem of estimating the parameters of the model, the question arises of the non-uniqueness of the solution. On the example of a specific reaction, the need to analyze the identifiability of the model before carrying out numerical calculations to determine the parameters of the reaction model was demonstrated.

Ethylidene dibutyrate and heptylidene diacetate decompose in the vapor state at temperatures between 200° and 300 °C. to form an aldehyde and an anhydride. The reactions are homogeneous, unimolecular, and complete. The activation energy is the same as that previously found for other members of this homologous series. Ethylidene dibutyrate decomposes at the same rate as ethylidene diacetate, and thus provides further evidence that the specific reaction velocity is independent of the size of the anhydride radicals. Heptylidene diacetate decomposes at the same rate as butylidene diacetate. This indicates that after the aldehyde radical has attained a certain size (three or four carbon atoms) the addition of –CH2− groups leaves the specific reaction velocity unchanged. The velocity constants are given by the equations[Formula: see text]
