The purpose of this paper is to examine the issue of at‐risk students in a rural district in Midwestern USA.

This field‐based research study used a qualitative embedded case study of a middle and high school informed by an appreciative inquiry theoretical research perspective to identify a positive core of teacher and administrator experiences related to at‐risk students. At‐risk students are those who under‐perform in mandated academic assessments as well as school‐related academic achievement. Social capital and appreciative inquiry served as theoretical perspectives. Focus groups, semi‐structured interviews, and an online survey were the primary data‐gathering methods.

Three findings illustrated the gap between present practice and the ideal state. The research team concluded that there was a foundation of positive core experiences from which to build on the espoused theory of caring professed by teachers and administrators.

The study's results can further teachers' and administrators' understanding of their problem‐based language that emphasizes the deficits of at‐risk students and their parents.

This study aims to review the recent advancements in high entropy alloys (HEAs) called high entropy materials, including high entropy superalloys which are current potential alternatives to nickel superalloys for gas turbine applications. Understandings of the laser surface modification techniques of the HEA are discussed whilst future recommendations and remedies to manufacturing challenges via laser are outlined.

Materials used for high-pressure gas turbine engine applications must be able to withstand severe environmentally induced degradation, mechanical, thermal loads and general extreme conditions caused by hot corrosive gases, high-temperature oxidation and stress. Over the years, Nickel-based superalloys with elevated temperature rupture and creep resistance, excellent lifetime expectancy and solution strengthening L12 and γ´ precipitate used for turbine engine applications. However, the superalloy’s density, low creep strength, poor thermal conductivity, difficulty in machining and low fatigue resistance demands the innovation of new advanced materials.

HEAs is one of the most frequently investigated advanced materials, attributed to their configurational complexity and properties reported to exceed conventional materials. Thus, owing to their characteristic feature of the high entropy effect, several other materials have emerged to become potential solutions for several functional and structural applications in the aerospace industry. In a previous study, research contributions show that defects are associated with conventional manufacturing processes of HEAs; therefore, this study investigates new advances in the laser-based manufacturing and surface modification techniques of HEA.

The AlxCoCrCuFeNi HEA system, particularly the Al0.5CoCrCuFeNi HEA has been extensively studied, attributed to its mechanical and physical properties exceeding that of pure metals for aerospace turbine engine applications and the advances in the fabrication and surface modification processes of the alloy was outlined to show the latest developments focusing only on laser-based manufacturing processing due to its many advantages.

It is evident that high entropy materials are a potential innovative alternative to conventional superalloys for turbine engine applications via laser additive manufacturing.

Additive manufacturing (AM) has the potential to transform the organisation of all the activities carried out by firms. The growing diffusion of these technologies is increasingly challenging multinational enterprises to reinvent their businesses. Accordingly, many scholars argue that AM may reduce countries’ participation in global value chains (GVCs) or, at least, affect GVCs’ geography, length and further developments. However, so far, the lack of available data on the real worldwide diffusion of these technologies has precluded the possibility to study this phenomenon from an empirical standpoint.

This study investigates AM technologies, with a particular focus on their possible impact on GVCs, in the framework of the current debate in international business. In order to examine this relationship and overcome the lack of adoption data, the authors identify a potential proxy of AM diffusion – that is, patenting activity. Coherently, the authors employ this proxy and a country-level measure of GVC participation (i.e., the Share of Re-Exported Inputs on Total Imported Inputs) to empirically investigate the role of AM in influencing countries’ participation to GVCs. This country-level analysis is focussed on three specific industries and the aggregate economy in 58 countries for the period 2000–2014.

The results show that AM decreases a country’s participation in GVCs, both at the country level and, in particular, in the sectors which are more likely to be affected by AM technologies. This evidence suggests that this phenomenon might be induced by a decreasing reliance on intermediates processed abroad, hence an increasing importance of domestic goods, manufactured via AM.

This chapter elucidates how digital citizenship regimes may be rescaling nation-states. In order to shed light on this phenomenon, the chapter introduces and answers three main research questions to unfold the content of this book as follows: (1) How will nation-states in Europe evolve in the aftermath of the emerging digital citizenship regimes? (2) Against the backdrop of the COVID-19, will the urban age reconfigure the technopolitics of European nation-states through new digital citizenship regimes (Moisio, 2018)? (3) And ultimately, will Europe evolve towards a post-national technopolity from a platform of established nation-states headed for a city-regionalised federal network of nations determined voluntarily and democratically through blockchain (Bauböck & Orgad, 2019; Calzada, 2018a, 2022; Calzada & Bustard, 2022; De Filippi & Lavayssiére, 2020; De Filippi, Mann, & Reijers, 2020; Keating, 2017; Keating, Jordana, Marx, & Wouters, 2019; Orgad & Bauböck, 2018)?

This paper aims to examine the link between information systems (IS) agility, HR performance management systems and job satisfaction using organizational information processing theory. The objective of this study answers the following questions: How does use of different IS agility impact HR systems and job satisfaction? What are the connecting pathways by which IS agility affects HR systems and job satisfaction?

The authors developed a theoretical framework based on the organizational information processing theory and collected primary data through an online-based questionnaire. Following these procedures, the authors analyzed the data using structural equation modeling (SEM).

SEM analysis of the data from 150 respondents supports the organizational information processing theory. The authors proposed eight hypotheses, and only one was rejected.

The data were collected from South Africa only, which is an emerging economy, and these cross-sectional data were gathered from the perspectives of the respondents.

The present paper empirically tests the conceptual model through the lens of organizational information processing theory.

Trade and investment flows into less-advanced economies could bring about important technological spillovers that could boost firm-level productivity and bolster their long-term economic growth. However, learning by doing and various forms of innovation activities are typically underprovided in a laissez faire policy environment. This brief paper outlines some of the motivations for public sector interventions to support learning by doing and stronger technological spillovers. The paper aims to discuss these issues.

To accomplish this, the paper provides a brief discussion of three key areas for policy attention, covering: the features that make international production networks fertile platforms for these spillovers; the opportunities for technology spillovers in the services sector; and the challenges associated with policies to link SMEs into these sectors that are fertile ground for technology spillovers and innovation.

This paper concludes by presenting a few possible guidelines on innovation and technology policy based on the lessons of industrialization attempts in the last several decades. A key insight tying these strategies together is that of creating incentives to compete and innovate, and ensuring that support is outcome oriented and temporary.

This paper contributes to the literature and practitioner-oriented scholarship by providing a clear framework for thinking about how to promote technology spillovers from trade and investments, as part of new industrial policies.

The examination of products of aqueous and non aqueous corrosion is carried out to obtain information about one of a combination of aspects such as composition, hardness, stress level, adhesion to basis metal and other mechanical properties (figure 1). A number of techniques are avialable to investigate corrosion products and some of these techniques have found greater application with products of aqueous corrosion and some with products of gaseous corrosion. This paper presents the technqiues available for obtaining information about the various aspects mentioned above and discusses the main characteristics, nature of data obtainable, advantages and limitations of some of the less know techniques.

Polymer Structure. A number of articles describe basic research on polymers of interest to the paint industry. Thus Sperling [Journal of Polymer Science, Macromolecular Reviews, 12 (1977) p. 141] describes interpenetrating polymer networks as structures which result when a crosslinked polymer is swelled by a monomer which contains also a crosslinking or polymerising agent. The monomer is thus polymerised in situ, presumably in the voids and intersticies provided by the initial crosslinked polymer. In this way, Sperling describes the morphology and mechanical properties of interpenetrating polymer networks.
