Decreasing energy demand due to improved building standards requires the development of new biomass combustion technologies to be able to provide individual biomass heating solutions. The purpose of this paper is, therefore, the development of a pellet water heating stove with minimal emission at high thermal efficiency.

The single components of a 10 kW water heating pellet stove are analysed and partly redesigned considering the latest scientific findings and experimental know‐how in combustion engineering. The outcome of this development is a 12 kW prototype which is subsequently down‐scaled to a 6 kW prototype. Finally, the results of the development are evaluated by testing of an accredited institute.

Based on an existing pellet water heating stove, the total excess air ratio was reduced, a strict air staging was implemented and the fuel supply was homogenized. All three measures improved the operating performance regarding emissions and thermal efficiency. The evaluation of the development process showed that the CO emissions are reduced by over 90 per cent during full load and by 30‐60 per cent during minimum load conditions. Emissions of particulate matter are reduced by 70 per cent and the thermal efficiency increased to 95 per cent.

The result represents a new state of technology in this sector for minimal emissions and maximal thermal efficiency, which surpasses the directives of the Eco label “UZ37” in Austria and “Blauer Engel” in Germany, which are amongst the most stringent performance requirements in the European Union. Hence this design possesses a high potential as heating solution for low and passive energy houses.

The purpose of this paper is to present and discuss the methodological approach and the results of the investigation of greenhouse gas emission abatement costs in Upper Austria.

The assessment covers the quantification of marginal abatement costs (MACs) of greenhouse gas (GHG) emissions and the emission reduction potentials of various energy efficiency and fuel switch measures with a special emphasis on the heat, electricity and transport sectors in Upper Austria during the period from 2010 to 2030.

The expert‐based assessment in Upper Austria shows negative abatement costs for 19 of 56 evaluated strategies. While these measures are very efficient from an economic point of view, the remaining 37 measures are associated with higher costs. The evaluation reveals a significant reduction potential of 5.2 million tons CO₂e (which represent 21 per cent) of the current GHG emissions in Upper Austria for the examined period.

MACs are generally limited to a certain time frame. Furthermore, the expert‐based approach is based on several assumptions and neglects behavioural and learning aspects.

This contribution uses a multi‐criteria approach that reveals the economic efficiency and the ecological effectiveness of the considered strategies/technologies with regard to greenhouse gas emission reductions, the improvement of the overall energy efficiency, and the competitiveness of a fuel switch towards renewable energy sources. Drawing upon the findings of this study, policy recommendations can be elaborated and the necessary improvements of the regulative framework can be implemented.

Purpose – The present study addresses: First, which traditions are currently lived in the Swiss Armed Forces? Second, which traditions are viewed in positive or negative terms and why is this so? And finally, which traditions have disappeared and which are wished for?

Methodology/approach – Two separate surveys were conducted by the authors of this study in an attempt to answer these questions. For the first survey, qualitative interviews were conducted with 50 professional and militia military commanders in order to get the internal perspective. For the second survey, a representative sample of 1,200 Swiss voters was interviewed in an attempt to get the external perspective.

Findings – The main findings show that there are few formal traditions in the Swiss Armed Forces. The republican self-concept and the decentralized political system in Switzerland have significantly influenced the meaning of traditions and their practice. Moreover, traditions mainly serve to integrate cadres and soldiers into the military. The majority of traditions is informal or a combination of formal (top-down) and informal (bottom-up) traditions. Lost traditions not only fell victim to structural changes, but their purpose was also questioned by commanders. Two major military reforms as well as societal change are the main reasons for the disappearance of traditions in the Swiss Armed Forces. The results show a high degree of congruence with the qualitative survey. In short, the Swiss population generally views military traditions in favorable terms. In particular, it endorses traditions that serve to foster a sense of community and impart knowledge. However, traditions that stress manhood and bravery are strongly rejected.

Research limitations/implications – The approach could be applied to other cases. Case studies may be generalized in a conceptual sense.

Originality/value of paper – Case study with broader practical and research implications, invites international comparative research.

People believe that they know who they are and that who they are matters for what they do. These core beliefs seem so inherent to conceptualizations of what it means to have a self as to require no empirical support. After all, what is the point of a concept of self if there is no stable thing to have a concept about and who would care if that concept was stable if it was not useful in making it through the day? Yet the evidence for action-relevance and stability are surprisingly sparse.

This paper outlines the identity-based motivation theory, a theoretical approach that takes a new look at these assumptions and makes three core predictions as to when an accessible self-concept influences behavior. These are termed “dynamic construction”, “action-readiness”, and “interpretation of difficulty”. That is, rather than being stable, which identities come to mind and what they mean are dynamically constructed in context.

People interpret situations and difficulties in ways that are congruent with the currently active identities and prefer identity-congruent to identity-incongruent actions. When action feels identity-congruent, experienced difficulty highlights that the behavior is important and meaningful. When action feels identity-incongruent, the same difficulty suggests that the behavior is pointless and “not for people like me.”

We integrate cross-cultural literature with broader literature in survey methodology, human cognition, and communication. First, we briefly review recent work in cognitive survey methodology that advances our understanding of the processes underlying question comprehension and response. Then, using a process model of cultural influence, we provide a framework for hypothesizing how cross-cultural differences may systematically influence the meaning respondents make of the questions that researchers ask, how memory is organized, and subjective theories about what constitutes an appropriate answer and therefore the answers participants are likely to give.

Entrepreneurial identity aspiration refers to the desire to occupy an entrepreneurial role in the future and is an essential impetus for initially engaging in entrepreneurial activities. Building on identity theory, the article investigates the effects of personal attitudes, experiences and inclination towards specific practices on the strength of entrepreneurial identity aspiration.

This article applies multiple linear regression analysis to test the developed hypotheses on an original sample of 127 vocational college students in Austria.

Results show that risk-taking propensity, proactiveness, entrepreneurial self-efficacy and competitiveness drive entrepreneurial identity aspiration. The effects of innovativeness and need for achievement motivation are nonsignificant. Data further suggest that entrepreneurial identity aspiration is related to gender, while entrepreneurial exposure and previous entrepreneurship education show no or adverse effects.

Based on our findings, the authors argue that education should focus on teaching and discussing the identified attitudes and inclinations to foster the formation of entrepreneurial identities. Doing so increases students' aspirations and provides them with the necessary cognitive underpinnings for subsequent entrepreneurial action. The article suggests action-based teaching to achieve this goal.

This article is the first to investigate antecedents of entrepreneurial identity aspiration by connecting it to essential concepts of entrepreneurship research. The authors extend previous work on entrepreneurial identity and add to the theoretical approaches for research in entrepreneurship education. Furthermore, the article points out central aspects that should receive additional attention in educational settings.

The purpose of this chapter is to build a new framework for understanding the antecedents of emotional well-being across different psychological states, situations, and cultural settings. In this regard, we develop propositions regarding causal relationships between self-uncertainty and emotional well-being in the context of social comparison and in two different culture types: dignity and honor.

Based on a literature review, this chapter connects empirical evidence in three areas of research. (1) self-uncertainty literature, (2) emotional well-being, and (3) cross-cultural psychology to propose a new conceptual framework for understanding the relationship between self-uncertainty and well-being across different cultural settings.

The main finding of this chapter is a model that explains how emotional well-being is comprised of three elements of the psychological state, situation, and culture. We seek to explain how and why different cultures and psychological states might have different effects on human emotions. We propose mediators in order to demonstrate how culturally determined notions of self-construal, self-worth, and social order mediate the relationship between self-uncertainty and emotional well-being.

We limited our theorizing to investigate only two broad culture types: honor and dignity. Clearly, there are many more nuances of national culture than this. In addition, our model limited to investigate the role of social comparison among other possible mechanisms to reduce the uncertainty.

The practical implication of our theory is that it enables leaders to gain a more holistic perspective of emotional well-being in their organizations. In particular, in international organizations, leaders have to pay attention to the cultural background of their employees. This, in turn, enables leaders to understand the antecedents of social comparison and emotional well-being in their employees.

This chapter proposes a holistic model that explains the simultaneous effects of different psychological states, situations, and cultures.

It is well known that information behaviour can be biased in countless ways and that users of web search engines have difficulty in assessing the credibility of results. Yet, little is known about how search engine result page (SERP) listings are used to judge credibility and in which if any way such judgements are biased. The paper aims to discuss these issues.

Two studies are presented. The first collects data by means of a controlled, web-based user study (N=105). Studying judgements for three controversial topics, the paper examines the extent to which users agree on credibility, the extent to which judgements relate to those applied by objective assessors and to what extent judgements can be predicted by the users’ position on and prior knowledge of the topic. A second, qualitative study (N=9) utilises the same setup; however, transcribed think-aloud protocols provide an understanding of the cues participants use to estimate credibility.

The first study reveals that users are very uncertain when assessing credibility and their impressions often diverge from objective judges who have fact checked the sources. Little evidence is found indicating that judgements are biased by prior beliefs or knowledge, but differences are observed in the accuracy of judgements across topics. Qualitatively analysing think-aloud transcripts from participants think-aloud reveals ten categories of cues, which participants used to determine the credibility of results. Despite short listings, participants utilised diverse cues for the same listings. Even when the same cues were identified and utilised, different participants often interpreted these differently. Example transcripts show how participants reach varying conclusions, illustrate common mistakes made and highlight problems with existing SERP listings.

This study offers a novel perspective on how the credibility of SERP listings is interpreted when assessing search results. Especially striking is how the same short snippets provide diverse informational cues and how these cues can be interpreted differently depending on the user and his or her background. This finding is significant in terms of how search engine results should be presented and opens up the new challenge of discovering technological solutions, which allow users to better judge the credibility of information sources on the web.

The study aims to drive conceptual clarity around resistance to information technology projects, integrating multiple facets of the phenomenon from earlier studies.

The study conducts a meta-synthesis of qualitative studies on resistance to technology projects; it analyzes those studies at a case-specific level, compares and contrasts emergent concepts against each other, and “translates” those to the rest of the studies. The study uses the seven-step meta-ethnography method by Noblit and Hare to reciprocally translate emergent concepts to construct the conceptual model.

Through meta-synthesis, the study derives a new conceptual model for resistance to information technology projects, exemplifying how the identified antecedents create user resistance and how the phenomenon progresses within organizations.

This study enriches the observations and conclusions of past individual studies while explicating various facets of the mechanisms that generate and progress technology resistance within organizations. It offers fresh insights into the equivocal nature of the phenomenon and the distinctive ways it progresses from individual to group level.

Many ambitious and costly digital transformation efforts do not succeed due to user resistance. Understanding the mechanisms that create user resistance can help organizations manage technology projects better, thereby reducing the technology assimilation gap and protecting returns on related investments.

There have been extensive studies on technology acceptance (enablers) within organizations, while those relating to technology inhibitors are somewhat limited. However, the symmetry of understanding between enablers and inhibitors is vital for organizations to assimilate promising technologies and transform their business models. This model uses a new lens of sensemaking theory to explain how the antecedents trigger perceived threats and resistance behavior; it highlights the nuances around the development of resistance within individuals and its progression to groups. The resultant model offers better generalizability in organizational contexts.
