Abstract

Purpose

Fused deposition modelling (FDM) is increasingly being explored as a commercial fabrication method due to its ability to produce net or near-net shape parts directly from a computer-aided design model. Other benefits of technology compared to conventional manufacturing include lower cost for short runs, reduced product lead times and rapid product design. High-performance polymers such as polyetherimide, have the potential for FDM fabrication and their high-temperature capabilities provide the potential of expanding the applications of FDM parts in automotive and aerospace industries. However, their relatively high glass transition temperature (215 °C) causes challenges during manufacturing due to the requirement of high-temperature build chambers and controlled cooling rates. The purpose of this study is to investigate the mechanical properties of ULTEM 1010, an unfilled polyetherimide grade.

Design/methodology/approach

In this research, mechanical properties were evaluated through tensile and flexural tests. Analysis of variance was used to determine the significance of process parameters to the mechanical properties of the specimens, their main effects and interactions. The fractured surfaces were analysed by scanning electron microscopy and optical microscopy and porosity was assessed by X-ray microcomputed tomography.

Findings

A range of mean tensile and flexural strengths, 60–94 MPa and 62–151 MPa, respectively, were obtained highlighting the dependence of performance on process parameters and their interactions. The specimens were found to fracture in a brittle manner. The porosity of tensile samples was measured between 0.18% and 1.09% and that of flexural samples between 0.14% and 1.24% depending on the process parameters. The percentage porosity was found to not directly correlate with mechanical performance, rather the location of those pores in the sample.

Originality/value

This analysis quantifies the significance of the effect of each of the examined process parameters has on the mechanical performance of FDM-fabricated specimens. Further, it provides a better understanding of the effect process parameters and their interactions have on the mechanical properties and porosity of FDM-fabricated polyetherimide specimens. Additionally, the fracture surface of the tested specimens is qualitatively assessed.

This paper aims to present a conceptual framework for the emerging field of green energy platform economics.

Abstract

Purpose

This paper aims to present a conceptual framework for the emerging field of green energy platform economics.

Design/methodology/approach

The authors develop a conceptual framework based on a careful review of the existing literature, and research into the current provider landscape and insights from academic and industry experts. The authors also examine the implications for the energy sector’s value chain and derive a research agenda based on those areas where research still needs to be pursued.

Findings

The framework combines the spatial characteristics of platform models (residential/mobile) with the different types of platform business model (B2C/C2C/C2Grid). Using this framework, the authors illustrate how green energy platforms can fundamentally disrupt the conventional electricity value chain by enabling prosumers to market their assets, creating new arenas for trading and collaboration, and by increasing transparency and competition in the sector. The authors also identify areas where more research is required, particularly empirical studies into energy forms other than electricity and analyses of currently underrepresented aspects such as user interfaces and social interactions.

Social implications

Green energy platforms have the potential to contribute meaningfully to the energy sector’s decarbonization, digitalization and decentralization, and hence to the deceleration of climate change.

Originality/value

This paper is among the first to provide a holistic perspective on platformization in the energy sector. It also offers a new perspective on platform economics in general that is based on the unique characteristics of energy as an economic good (intangibility, homogeneity, credence good).

Abstract

Purpose

To explain how the components of attraction theory work in unison to prompt students to take an initial stimulus and progress through critical thinking processes and into knowledge acquisition, organization, and synthesis.

Design/methodology/approach

Although schema theory has an important role in understanding knowledge acquisition, it does not provide directives for how to plan instruction so students can build their understandings and comprehension of subject matter. This chapter outlines a pedagogical approach to the implementation of a new theory of learning that builds on cognitive science, affect, and interest.

Findings

Students can become re-attracted to learning through effective teaching inclusive of a jolt, curiosity, retrieving explanations, counterexamples, clarifications, and embedding that information within schemata.

Practical implications

Proactive investigations and continued research on attraction theory can enrich our understanding of teaching and learning, provide answers for what works in the classroom, and equip us with tools from which to select for unique classroom circumstances.

Abstract

Purpose – The author examines the implementation and characteristics of teacher evaluation and explores their associations with improvement in teachers’ practice of constructivist instruction.Methodology – This quantitative study uses statewide longitudinal Teachers’ Opportunity to Learn survey data collected in 2009 and 2010 from middle school mathematics teachers in Missouri and estimates a series of value-added models with two-level Hierarchical Linear Modeling.Findings – Teachers in this study were mainly evaluated by principals who conducted classroom observations and held face-to-face meetings to evaluate teaching practice and professional development activities. The study provides empirical evidence and support for the use of multiple evaluators with multiple evaluation data and outcomes in teacher evaluation. Additionally, it highlights the potential benefits of focusing on teachers’ instructional data instead of student achievement in teacher evaluation in order to improve their teaching practice.Research limitations – This study focused on middle school mathematics teachers in a single state in the United States. Whether these findings can be generalized to teachers of other subject areas or grades, or to states with different policy contexts, or to countries with country-specific structural, cultural, and social differences is unknown.Value – This study is the first effort to systematically examine teacher evaluation practices across a single state and provide empirical evidence on the relationships between the implementation characteristics of teacher evaluation and improvement in teachers’ instructional practice. Findings of this study provide school, district, state, federal, and international policymakers and administrators with important, up-to-date information on teacher evaluation at the middle-school level in the United States.

The purpose of this paper is to establish the relationship of emotional intelligence with the cultural quotient (CQ) and change readiness of Indian managers in the service sector.

Abstract

Purpose

The purpose of this paper is to establish the relationship of emotional intelligence with the cultural quotient (CQ) and change readiness of Indian managers in the service sector.

Design/methodology/approach

Using purposive sampling, data were collected from 109 middle-level managers of the Indian service sector, comprising of top five contributing industries to the GDP of India (retail, real estate, banking and insurance, information technology and tourism). Emotional quotient (EQ) was measured by using the Emotional Intelligence Scale by Singh (2004), Cultural Intelligence Scale by Ang and Dyne (2008) was used to calculate CQ, and for measuring change readiness, Change Readiness Questionnaire developed by Kriegel and Brandt (1996) was used.

Findings

EQ has a significant and positive relationship with CQ (r=0.537) and the subscales of CQ are positively related with EQ. EQ is significantly positively related with change readiness (r=0.513) and the subscales of change readiness are also positively related with EQ.

Research limitations/implications

The research is limited to only 109 middle-level Indian managers of the service sector.

Originality/value

Training of managers on Emotional Intelligence can lead to better handling of conflict and erase misunderstandings because of cultural diversities and could also help managers to deal with change more effectively and appropriately.

Abstract

Purpose

There is a growing trend in higher education institutions to develop multi-disciplinary approaches to education for sustainable development and to implement student-centered and problem-based methodologies to increase student engagement and satisfaction. This paper aims to present an innovative methodology to increase student awareness about the effects of economic decisions on sustainability.

Design/methodology/approach

This method uses a videogame and two board games to simulate three spheres of economic interaction, namely, local, national and international. For every sphere, three key economic sectors and their relationships with fundamental sustainable development goals (SDGs) are addressed. This study uses pre- and post-simulation data to analyze the students’ perceptions regarding the usefulness of the simulations and their awareness about the effects of economic decisions on sustainability.

Findings

The implementation of this teaching and learning method demonstrated not only that active learning can effectively increase student awareness about the potential social and environmental consequences of economic decisions but also that students perceive games and simulations as useful teaching and learning tools.

Social implications

Students in these areas need to learn not only how to transform original ideas into successful projects but also to align financial results with social and environmental objectives. The methodology presented in this research allows to enhance learning from a multi-disciplinary perspective, helping the students to analyze different economic sectors and their connection with a number of SDGs through the lens of public economics.

Originality/value

The outbreak of the COVID-19 virus has shown the effects of a global pandemic at the economic, social and environmental levels. This paper presents an innovative active learning framework to increase sustainability awareness among students of economics, business and management.

Abstract

Purpose

The purpose of this paper is to focus on the building of consumer–brand identification through the use of two themes (underdog and topdog) in the design of brand storytelling. It proposes that the underdog theme is superior because it is more effective in immersing readers in the story and generates higher emotional responses. The moderating effect of consumers’ implicit mindsets is also explored.

Design/methodology/approach

An experimental study with a single-factorial design is conducted with 301 consumers assigned at random to one of two brand storytelling conditions: underdog theme or topdog theme.

Findings

The results show a full mediating effect of the underdog (vs topdog) theme on brand identification through reader immersion and empathic feelings.

Research limitations/implications

The use of a fictitious brand and a specific product category may limit the generalizability of the results.

Practical implications

Placing the brand in a story with an underdog plot is more effective in catching consumers’ attention than using a topdog brand story. In particular, using an underdog theme is a good approach for targeting consumers who have a growth mindset.

Originality/value

This study explains the persuasiveness of brand storytelling in terms of the characteristics of the storytelling itself rather than the individual characteristics of consumers (e.g. their own underdog dispositions). The results also suggest that the implicit mindset of the individual plays a role.
