Abstract

Purpose

This study aims to understand master’s students’ experiences of service-learning, following their participation in a workshop with local social innovators whose activities had contributed to combating poverty in East Africa and to determine how this participation affected work on the students’ theses. The authors also explored possible gender differences in this context.

Design/methodology/approach

The study was based on pretest–posttest mixed methods research design. Data were collected from master’s students within the social sciences and science, technology, engineering and mathematics (STEM) disciplines, respectively, in Kenya and Uganda, via surveys and interviews before the workshop, immediately afterwards and six months later.

Findings

Students’ immediate experience was that the workshop contributed to increased critical awareness, adoption of transdisciplinary community-serving approaches and strengthened self-confidence. Six months later, most had related their projects to social problems (e.g. poverty) in their communities. Moreover, the results motivated integration of gender-sensitive curricula based on service-learning in East Africa.

Practical implications

Based on the results, the authors suggest a framework for gender-sensitive curriculum development that can stimulate service-learning in master’s students. Implementation of such a curriculum could eventually contribute to community development, including, e.g. poverty reduction.

Originality/value

Studies on service-learning are rare in Africa, especially in postgraduate education. Gender-sensitive studies on service-learning are generally scarce and the same holds for studies on encouraging STEM students to integrate social innovation into their thesis work. By combining these aspects, this study presents an original contribution to existing research.

Abstract

Purpose

The purpose of this paper is to provide a theoretical framework for conceptualizing critical and creative thinking within doctoral study and to illuminate the connecting and diverging points between the two phenomena in a way that clarifies their developmental relationships.

Design/methodology/approach

The conceptual framework is founded in a synthesized understanding of both new and established theories on critical and creative thinking, and worked out through a reconstruction and expanded re‐conceptualization of the Four C Model of Creativity.

Findings

The results show that responsible scholars are moved by both critical and creative thinking, which is conceptualized as critical creativity. The authors introduce the ECC‐model which illustrates how different Expressions of Critical Creativity (CC) is manifested in scholarship: Experiential CC (in cognition), Experimental CC (in action), Enunciated CC (in speech), and Eulogized CC (in recognition). Whereas Experiential, Experimental and Enunciated CC constitute important fields of developmental practice in doctoral education, Eulogized CC is a possible outcome of the completed doctorate. It appears that Enunciated CC especially seems to be a field of urgent need for further development.

Originality/value

The paper offers a conceptual framework for new ways of understanding critical creativity in doctoral education by outlining how critical creativity is manifested in an educational context. Thereby the authors provide a valuable tool for supporting doctoral students in becoming professional scholars through a pedagogy that is reflective, integrative and deliberate.

Abstract

Purpose

The purpose of this paper is to investigate the diffusion dynamics of electric and hybrid commercial vans and its enabling factors in the city logistics (CL) contexts. The case of parcel delivery in Torino, Italy, is considered. Attention is paid to the influence on the choice of low impact vehicles of not only public strategies but also operational aspects characterizing urban freight distribution systems.

Design/methodology/approach

A System Dynamics model based on the Bass diffusion theory computes the number of adopters of low-emission vehicles together with the quantity of vans required and the associated economic savings. The model includes variables about freight demand, delivery frequency, van carrying capacity, routes, stops, distances traveled, and vehicle charging stations. A sensitivity analysis has been completed to identify the main diffusion levers. The focus is on advertising and other drivers, such as public contributions, taxes traditional polluting vehicles are subjected to, as well as on routing optimization strategies.

Findings

Advertising programs, green image, and word-of-mouth drive market saturation, although in a long time period. In fact, low-impact vehicles do not offer any economic advantage over traditional ones requiring higher investment and operating costs. Public incentives to purchase both green vehicles and charging stations, together with carbon taxes and a congestion charge affecting polluting vehicles, are able to shorten the adoption time. In particular, public intervention reveals to be effective only when it unfolds through a number of measures that both facilitate the use of environmentally friendly vehicles and discourage the adoption of traditional commercial vans. Route optimization also hastens the complete market saturation.

Research limitations/implications

This work fosters research about the mutual relationships between the diffusion of low-emission commercial vehicles and the operational and contextual CL factors. It provides a structured approach for investigating the feasibility of innovative good vehicles that might be part of assessments of CL measures and requirements. Finally, the model supports studies about the cooperation among stakeholders to identify effective commercial vehicle fleets.

Practical implications

This study fosters collaboration among CL players by providing a roadmap to identify the key factors for the diffusion of environmentally friendly freight vehicles. It also enables freight carriers to assess the operational and economic feasibility of adopting low-impact vehicles. Finally, it might assist public authorities in capturing the effects of new urban transportation policies prior to their implementation.

Originality/value

Most of the current CL literature defines policies and analyzes their effects. Also, there are several contributions on the diffusion of low emission cars. The present study is one of the first works on the diffusion of low-impact commercial vehicles in urban areas by considering the associated key operational factors. A further value is that the proposed model combines operational variables with economic and environmental issues.

Abstract

Purpose

The purpose of this paper is to obtain high-temperature-resistant material with high density and to conduct microstructural investigations of 3D-printed Ni-based alloy 713C specimens.

Design/methodology/approach

High-density specimens of Ni-based alloy 713C were obtained by the optimizing selective laser melting (SLM) process parameters and an X-ray diffraction (XRD) analysis confirmed the occurrence of γ and γ′ phases and the presence of carbides in the SLM-manufactured Ni-based alloy 713C. The analysis of electron backscatter diffraction (EBSD) studies suggested a preferred 〈100〉 direction orientation and low angle misorientation for the SLM specimens.

Findings

The high-density specimens of Ni-based alloy 713C were obtained by the optimized SLM process parameters. XRD analysis confirmed the presence of γ and γ′ phases and carbides in the SLM-manufactured Ni-based alloy 713C. Analysis of EBSD studies suggested a preferred 〈100〉 direction orientation and low angle misorientation for the SLM specimen.

Originality/value

In this study, 3D-printed Ni-based alloy 713C with a high density of 99% was obtained for the first time, to the best of the authors’ knowledge.
