This study aims to characterize the suitability of a direct extrusion process in the fused layer manufacturing (FLM)-method under processing of granulated plastics.

Abstract

Purpose

This study aims to characterize the suitability of a direct extrusion process in the fused layer manufacturing (FLM)-method under processing of granulated plastics.

Design/methodology/approach

In this paper, a granulate-based direct extrusion system in the FLM method is presented. This system is characterized with respect to the strand deposition mechanism and resulting component properties (geometrically and mechanically).

Findings

The extruder output could be identified as a linear relation between the applied extruder speed and the resulting mass flow. A developed model for the material and temperature-dependent strand deposition process was validated under experimental investigations. Further, it was possible to define process windows to realize desired strand widths and strand heights. In addition, analyses were conducted to determine the tensile strength transversely to the orientation of the layer plane.

Research limitations/implications

The extrusion system was characterized under the processing of materials ABS Magnum 8434 and PLA Ingeo 4043D. Due to the restricted choice of materials, further investigations are planned under an extension of the test materials. Furthermore, the degree of the geometric complexity of the test components should be increased to finally characterize the process.

Originality/value

By means of the characterization of the direct extrusion system, it is possible for users to classify the process and to use the process in specific application areas. In comparison to filament-based extrusion systems, significant advantages can be achieved by means of direct extrusion. These include, for example, the use of less expensive work materials (by factor >10), the use of existing test certificates and the advantage of higher mechanical properties. This makes it possible to meet modern product requirements and to produce competitive components.

Abstract

Purpose

This study aims to investigate the ways affective intensities arise in the intra-actions within an assemblage (three Black girls, objects such as computers and hoodies, institutionalized discourse associated with race and successful participation in schools) as the girls create multimodal responses to literature. This paper shows how the intra-actions among the girls and material objects produce affective intensities or new ways of being and becoming through which youth reauthor themselves as central and peripheral participants.

Design/methodology/approach

The authors present an illustrative case of the ways girls’ embodied literacy identities emerge when Jillian, Isa, and Rhianna intra-act with materials in an assemblage that includes their material-discursive positionings through qualitative and multimodal interaction analysis.

Findings

The analysis describes the ways the girls agentively participate through play, composing and moments of becoming (fluid subjectivities) that include emotive acts such as acts of solidarity, loving connectedness and possible frustration that inform who counts and who can be successful in the classroom.

Research limitations/implications

This single case study gives a descriptive, in-depth analysis of the ways affective intensities emerge as three girls respond to literature to understand their embodied and discursive practices within the composing process.

Originality/value

To fully understand agency and the students’ emergent subjectivities, the authors combine embodiment and material-discursive analysis to understand affective intensities that evolve during three Black girls’ composing processes and the ways the girls’ subjectivities shift within the intra-actions.

Abstract

Purpose

Literacy research exploring multimodal composition and justice-oriented children’s literature each have rich landscapes and histories. This paper aims to add to both of these bodies of scholarship through the emerging assemblage of Studio F, a fifth-grade classroom. The authors share poststructural analytic encounters with attention to the unexpected multimodal relationships and the justice-oriented talk and texts that emerged, as well as the classroom conditions that produce them.

Design/methodology/approach

The authors think with assemblage theory to examine the newness that emerged as one small group of students wrestled with the emerging instances of racism present in Freedom Summer by Deborah Wiles.

Findings

Together, the living arrangement of bodies, materials and discourses created openings for students’ explorations of race and racism.

Originality/value

This paper offers teachers and researchers space to rethink what is possible in the literacy classroom when the authors re-envision classrooms as vibrant assemblages, support emergent multimodal composing processes and follow students’ critical encounters toward justice-oriented literacies.

North America is both geographically large and demographically diverse, which makes a discussion about globalization in North America difficult to distinguish from globalization

Abstract

North America is both geographically large and demographically diverse, which makes a discussion about globalization in North America difficult to distinguish from globalization writ large. This chapter attempts to do so nonetheless by examining tangible, virtual, and envisioned versions of the globalization of education in North America specific to trends in immigration (and migration), identity, and imagination. A brief explanation of theories of globalization that intersect in the North American context includes world systems, neo-institutionalism, cosmopolitanism, neoliberalism, and post-colonialism, but could include many more. This chapter also suggests that the globalization of education in North America is not limited to the continent of North America due to the many external or global educational entanglements that North Americans have with other countries and regions worldwide.

Abstract

As an interruption to existing nationalistic and neoliberal frames, teachers are beginning to embrace cosmopolitanism to ground literacy instruction. The purpose of this chapter is to explore the possibilities and tensions of using a cosmopolitan approach to literacy instruction. This chapter presents a qualitative study of interviews with 24 educators from the United States, Belize, and China to examine curricular and instructional choices educators report using to promote students' global meaning-making and cosmopolitan worldviews. Findings include three themes: situated relevance, glocal connections, and intercultural collaboration. Participants reported that creating a welcoming environment and promoting equality in the local classroom is foundational to teaching students at the local or global level. Teaching global literacies included teaching about similarities and differences locally and internationally and making local–global connections on issues of importance to the students. Also, participants reported that for students to engage in global meaning-making, they needed to dialogue and collaborate with people from different countries. While the findings present possibilities, the discussion approaches the data through the lens of potential challenges. Some participants reported first helping students move beyond ethnocentric thinking and stereotypes through reflexive exercises so that students could constructively interact with peers cross-culturally. However, not all participants taught reflexivity or with a critical lens. This study may bring awareness to educators as to curricular choices and instructional processes that hold promise for promoting students' global meaning-making.

Abstract

Purpose

Since few studies have explored and advanced on the development of measures of knowledge waste, the purpose of this paper is to develop and validate a scale for measuring the waste of knowledge.

Design/methodology/approach

A research was carried out in Higher Education Institutions (HEIs) divided into five distinct stages, three qualitative and two quantitative. For the quantitative steps, a sample of 223 responses was obtained for the exploratory part and another sample of 614 responses for the confirmatory part of the study. Data analysis procedures involved Exploratory and Confirmatory Factor Analysis to test and validate the proposed scale.

Findings

A fifteen-item scale divided into four constructs was obtained after refinement of the proposed scale and validation procedures (convergent and discriminant validity). The scale also has satisfactory levels of reliability.

Research limitations/implications

The resulting scale was validated in a single institutional culture environment (HEIs in Southern Brazil). So it still should be tested in different organizational contexts and cross-culturally in different countries. The scale may be useful for decision-making improvement about knowledge management and waste reduction.

Practical implications

A scale with a practical and quick application is provided. Additionally, a classification of the waste of knowledge level was developed and it could be easily applied in different sectors or organizations.

Originality/value

The literature on waste of knowledge is limited and often confused with knowledge loss. This study provides a clear distinction between these topics, and it advances on the explanation and definition of knowledge waste. Also, it is the first study to offer a scale to measure the elements of knowledge waste.

Abstract

Chester Whitney Wright (1879–1966) received his A.B. in 1901, A.M. in 1902 and Ph.D. in 1906, all from Harvard University. After teaching at Cornell University during 1906–1907, he taught at the University of Chicago from 1907 to 1944. Wright was the author of Economic History of the United States (1941, 1949); editor of Economic Problems of War and Its Aftermath (1942), to which he contributed a chapter on economic lessons from previous wars, and other chapters were authored by John U. Nef (war and the early industrial revolution) and by Frank H. Knight (the war and the crisis of individualism); and co-editor of Materials for the Study of Elementary Economics (1913). Wright’s Wool-Growing and the Tariff received the David Ames Wells Prize for 1907–1908, and was volume 5 in the Harvard Economic Studies. I am indebted to Holly Flynn for assistance in preparing Wright’s biography and in tracking down incomplete references; to Marianne Johnson in preparing many tables and charts; and to F. Taylor Ostrander, as usual, for help in transcribing and proofreading.

Abstract

Purpose

This study employs the Social Identity Theory to examine the differential effects of personal and social dimensions of fear of missing out (FOMO) on sustainable food consumption (SFC) practices.

Design/methodology/approach

An online survey-based empirical study was conducted with 395 respondents. The data were analysed using structural equation modelling and Hayes process Macro in SPSS.

Findings

SFC was found to be positively influenced by personal FOMO. Contrary to expectations, social FOMO had a negative correlation with SFC. Social influence and social identity were shown to be positively correlated, whilst the social influence-SFC relationship was favourable. This approach was aided by social identity.

Research limitations/implications

The study supports personal FOMO as an SFC-influencing factor. It evaluates the differential effects of FOMO’s personal and social dimensions on SFC. It also demonstrates that social FOMO negatively affects SFC, contrary to expectations.

Practical implications

The study advises sustainable food firms to reduce personal FOMO via advertising and messaging.

Originality/value

This research is amongst the first to segregate the differential effects of social and personal FOMO regarding SFC behaviour. Research has examined FOMO as a higher-order construct involving social and personal aspects. Second, FOMO is often associated with negative behaviours including social media addiction and substance abuse. This FOMO-related research analyses a desired behaviour.

Abstract

Purpose

The purpose of this article is to analyze the optimization process in depth, elaborating on the components of the entire process and the techniques used. Researchers have been drawn to the expanding trend of optimization since the turn of the century. The rate of research can be used to measure the progress and increase of this optimization procedure. This study is phenomenal to understand the optimization process and different algorithms in addition to their application by keeping in mind the current computational power that has increased the implementation for several engineering applications.

Design/methodology/approach

Two-dimensional analysis has been carried out for the optimization process and its approaches to addressing optimization problems, i.e. computational power has increased the implementation. The first section focuses on a thorough examination of the optimization process, its objectives and the development of processes. Second, techniques of the optimization process have been evaluated, as well as some new ones that have emerged to overcome the above-mentioned problems.

Findings

This paper provided detailed knowledge of optimization, several approaches and their applications in civil engineering, i.e. structural, geotechnical, hydraulic, transportation and many more. This research provided tremendous emerging techniques, where the lack of exploratory studies is to be approached soon.

Originality/value

Optimization processes have been studied for a very long time, in engineering, but the current computational power has increased the implementation for several engineering applications. Besides that, different techniques and their prediction modes often require high computational strength, such parameters can be mitigated with the use of different techniques to reduce computational cost and increase accuracy.
