To present a new direct solution method for the Boltzmann‐Poisson system for simulating one‐dimensional semiconductor devices.

Abstract

Purpose

To present a new direct solution method for the Boltzmann‐Poisson system for simulating one‐dimensional semiconductor devices.

Design/methodology/approach

A combination of finite difference and finite element methods is applied to deal with the differential operators in the Boltzmann transport equation. By taking advantage of a piecewise polynomial approximation of the electron distribution function, the collision operator can be treated without further simplifications. The finite difference method is formulated as a third order WENO approach for non‐uniform grids.

Findings

Comparisons with other methods for a well‐investigated test case reveal that the new method allows faster simulations of devices without losing physical information. It is shown that the presented model provides a better convergence behaviour with respect to the applied grid size than the Minmod scheme of the same order.

Research limitations/implications

The presented direct solution methods provide an easily extensible base for other simulations in 1D or 2D. By modifying the boundary conditions, the simulation of metal‐semiconductor junctions becomes possible. By applying a dimension by dimension approximation models for two‐dimensional devices can be obtained.

Practical implications

The new model is an efficient tool to acquire transport coefficients or current‐voltage characteristics of 1D semiconductor devices due to short computation times.

Originality/value

New grounds have been broken by directly solving the Boltzmann equation based on a combination of finite difference and finite elements methods. This approach allows us to equip the model with the advantages of both methods. The finite element method assures macroscopic balance equations, while the WENO approximation is well‐suited to deal with steep gradients due to the doping profiles. Consequently, the presented model is a good choice for the fast and accurate simulation of one‐dimensional semiconductor devices.

Abstract

Purpose

The purpose of this publication is to present a didactic concept with the targeted impact of a positive future vision. This paper reflects the effect of local educational action on the development of regionally optimised visions in rural regions of a European industrial state, compared with a rural region in the developing country of Senegal.

Design/methodology/approach

An assessment and analysis of two conceptual approaches to education and technology is conducted with a view to participating in a future multicultural participatory design process, and identifying the chances that communities have to build future‐oriented structures that support local roots and development.

Findings

In the short‐term, the technological and material results are the targeted localisation of a windmill in the (physical and cultural) countryside. In the long‐term, educative and social results are expected to strengthen local civil society, which is initiated by empowering students through their self‐responsibility in the Alpine region of Greifenburg, Austria. The “windmill” in the region is a publicly visible sign and a technology‐based icon in the landscape, based on local consensus on several levels and inspiring further regional consensus on energy, climate protection and its active creation through entrepreneurship in civil society.

Originality/value

Technology serves as a catalyst to trigger social cohesion among multiple cultures in a region and to enhance conviviality.

Abstract

Purpose

Education for equity in global development and cultural diversity calls for professional capacity building to perceive diverse perspectives on complex procedures of globalisation. The discipline of human geography is such a “provider of perspectives”. The purpose of this paper is to propose a historic series of how theories of geography and human development have emerged.

Design/methodology/approach

This paper contributes to education and training by proposing a historic series of how theories of geography and human development have emerged.

Findings

The outcomes of this analysis of geographic paradigms offer options for the management of multicultural education in development. A critical synopsis and a combination of various paradigms on global development seem most promising for a holistic and comprehensive understanding of globalisation.

Research limitations/implications

In particular, recent developments in human geography exhibit rapidly changing paradigms (ironically called “the Latin America of sciences”) and are hence difficult to systematise.

Practical implications

Spaces are understood to be communicational spaces, the substrate of which is enabling communication technologies. The theoretical contemplations of this paper permit to design learning environments, learning styles and related technologies.

Social implications

Perception and understanding of contradicting theories on global (economic and human) development facilitate education fostering multiple cultures of understanding. The author's own professional experience shows that only esteem for all paradigms can provide the full picture. Success means “collective production of meaning”.

Originality/value

Understanding history frees us to reach future consensus.

Abstract

Purpose

Prior research in ingredient branding (IB) has identified several important decision variables consumers use when evaluating IB alliances. This exploratory research aims to investigate the relationship between these variables and consumers’ buying likelihood of the IB alliance and the relative importance of these variables for low- vs high-involvement product categories.

Design/methodology/approach

A study with the participation of 458 mTurkers was conducted and the data were analyzed using random forests.

Findings

Findings reveal relative importance of different variables for an IB alliance and that these differ for low- vs high-involvement categories.

Research limitations/implications

Being exploratory in nature, this research has several limitations, such as using only one high- and one low-involvement categories.

Practical implications

Results of this research will help brand managers as they make decisions entering an IB alliance as well as with investing their budget on different aspects of their brand, and tailoring their marketing activities for low- vs high-involvement product categories.

Originality/value

To the best of authors’ knowledge, this paper is the first to discuss the relative importance of different decision variables in an IB context empirically.

Abstract

Purpose

The purpose of the present paper is to describe a web-based consensus-finding procedure, resulting in an agreement among the group of participants representing global stakeholders regarding the interdisciplinary topic in a university master's seminar on “Global Studies”. The result of the collectively elaborated solution pertains to the forward-looking and jointly agreed topic of migration policies.

Design/methodology/approach

The core part of the web-based negotiation game “Surfing Global Change” utilised here is a controversial group discussion. A subsequent step creates an agreement among discussants. The group of participants, in this case co-authors of this paper, developed a final agreement on possible future political adaptations and guidelines to improve current standards in the global management of refugee and migration issues.

Findings

The findings offer several political possibilities for European and African states including structural recommendations as well as cooperative development policies.

Social implications

The result is a catalogue of tentative recommendations to improve international policies relating to current migration problems, here focused on migration between Africa and Europe.

Originality/value

Considering the creativity of the entire procedural structure combined with an ordered scientific methodology, the outcome could promise an interdisciplinary result. Effects of group dynamics, cooperation, scientific research and diplomacy are integrated into consensus building.

Abstract

Purpose

The purpose of this paper is to encourage a discourse aiming to better understand the “psycho-social situation” of many people – from a global perspective. The following “first hypotheses” are formulated; pointing to crucial “hidden agendas” which shall be “named” in order to focus attention towards these phenomena (“taming”).

Design/methodology/approach

Following the news and the “official” comments in Europe and America allow – almost demand – the formulation of “suspicions” with regard to “silent” (unconscious) shifts in the “loud” societies.

Findings

The present economic regime is broadening the division between rich and poor worldwide, as is known. However, there are also other, more hidden divisions emerging, especially between “official” (e.g. administration-announced) and “common” opinions and attitudes, despite a growing globalisation of information (access-wise and content-wise, not necessarily reaching out to all milieus).

Research limitations/implications

Formulating hypotheses can bring important issues to the forefront of attention within social science (e.g. starting a precautionary process also with regard to information).

Practical implications

This paper aims to deepen the understanding of the social structure of the (now almost) worldwide interconnected social communication network (including “scars”).

Social implications

Multicultural connectivity (understanding and exchange) is needed in order to solve (first perceive) the worldwide problems ahead of us.

Originality/value

Naming agendas of global dimensions that are perhaps largely hidden and not yet perceived (“named”).

Abstract

Purpose

On the educational level, this paper aims to show a practical case of dialogic web‐based learning. It has provided a consensus during a web‐based negotiation game between four different parties on poverty and inequality. On a multicultural level, this paper seeks to offer diverse cultures of argumentation on global poverty.

Design/methodology/approach

The methodology is a web‐based and real life negotiation game, namely “Surfing Global Change” which includes structured online review processes on literature‐based research and reflection.

Findings

The paper provides the consensus of four different parties on global development and poverty, and a new system of scaling development based on democratic decisions through a round table for all countries from the global north and the global south.

Research limitations/implications

The presented dialog and consensus‐finding process concentrates on poverty and inequality from the point of view of the G‐8, NGOs, the global rich and the global poor.

Originality/value

This research, based on literature, is formed through a dialog and consensus finding between four different parties (G‐8, NGOs, the rich and the poor).
