Abstract
Purpose
The purpose of this paper is to investigate of interphasial effects, including temperature dependency, within fiber reinforced polymers on the overall composite behavior. Providing theoretical and numerical approaches in terms of a consistent thermomechanical finite element method framework are further goals of this research.
Design/methodology/approach
Starting points for achieving the aims of this research are the partial differential equations describing the evolution of the displacements and temperature within a continuum mechanical setting. Based on the continuous formulation of a thermomechanical equilibrium, constitutive equations are derived, accounting for the modeling of fiber reinforced thermosets and thermoplastics, respectively. The numerical solutions of different initial boundary value problems are obtained by a consistent implementation of the proposed formulations into a finite element framework.
Findings
The successful theoretical formulation and numerical modeling of the thermoinelastic matrix materials as well as the thermomechanical treatment of the composite interphase (IP) are demonstrated for an epoxy/glass system. The influence of the IP on the overall composite behavior is successfully investigated and concluded as a further aspect.
Originality/value
A thermomechanical material model, suitable for finite thermoinelasticity of thermosets and thermoplastics is introduced and implemented into a novel kinematic framework in context of the inelastic deformation evolution. The gradually changing material properties between the matrix and the fiber of a composite are continuously formulated and numerically processed, in order to achieve an efficient and realistic approach to model fiber reinforced composites.

Abstract
The chapter presents recent development in the field of entrepreneurship education of several European universities – partners within Erasmus+ project on blended learning entrepreneurship course development, covering subjects from everyday instructional and practical approaches to support (under)graduate entrepreneurship and theoretical connections with modern worldwide educational and socioeconomic policies. Theoretical overview of the subject of entrepreneurship education is presented in the first part, and in the second part, good practice of BLUES Entrepreneurship course is discussed (BLUES Erasmus+ Programme of the European Union: Blended-learning international entrepreneurship skills programme; European Entrepreneurship Experience project). The chapter discusses the needs of universities and university professors and entrepreneurship instructors by highlighting how blended learning addresses some challenges of entrepreneurship education implementation while also brings some new challenges in managing such a course. Blended learning is suggested as a conducive environment for entrepreneurial learning in both academic and nonacademic settings. Based on the presented methodology entrepreneurship professors are able to implement and/or adjust the BLUES methodology within their own course, parts of it or the whole course that is provided through online massive open online courses (MOOCs) and toolkit for face-to-face exercises in class. Chapter provides a systematic and integrated perspective with relevance for business students, educators and policymakers.

Abstract
Purpose
The purpose of this study is to empirically investigate the role of dynamic capabilities, specifically the sequence of sensing, seizing, and transforming capabilities, in highly uncertain, emerging technology environments. Focusing on the extended reality industry, the study aims to understand the antecedents to these dynamic capabilities, their sequential nature, and their subsequent impact on innovation and company performance.
Design/methodology/approach
Based on a survey of 130 German companies in the extended reality sector, we built a structural equation model that explores the relationship between dynamic capabilities, their antecedents, and their effect on innovation and company performance.
Findings
The analysis suggests that sensing capabilities positively influence seizing and transforming capabilities, while seizing directly contributes to transforming. Transforming capabilities are linked to improved innovation performance, which in turn boosts company performance. Organizational ambidexterity, market orientation, and technology orientation are found to be crucial antecedents, accounting for 33.1% of the variance in sensing capabilities.
Originality/value
This research illuminates the interdependence of dynamic capabilities in highly uncertain business environments, such as emerging technology markets. It contributes original insights by elucidating the sequential nature of dynamic capabilities and identifying their vital antecedents. It also enlarges the understanding of how dynamic capabilities impact firms’ innovation performance.

Abstract
In the last 3 decades, the rapid growth of tourism activities is evident. Globally, tourism is becoming of prime importance for the development of local economies. A similar trend is observed in the Balkan region and in Bosnia and Herzegovina. The total contribution of tourism in GDP of Bosnia and Herzegovina growth is evident, from 2.0% in 2011 to 2.6% in 2017, with bright forecasts from United Nations World Tourism Organisation (UNWTO) which predicted the 3.4% share of tourism in national GDP by 2028. With aim to indicate the development potential of the touristic sector, gastro tourism sector was ‘screened’ through questionnaires with tourists (n = 245) and with destination management offices (n = 7). This approach should provide insights into stakeholder's capability to understand and react to new challenges that brings gastro tourism; insights into the current gastro offer; and insight into profile, motives and overall tourist's satisfaction. Main findings of the study show that the stakeholders' activities and understandings are not enough to provide a unique identity to the sector. On the other hand, tourists' profile and expectations rise with level and type of information they gather, and this study shows that tourists' expectations are more influenced by the age, education and gender of the tourists', while their satisfaction depends on the working status and monthly income. Future research, which is also the main implication of this study, should follow three main avenues: (1) how to build efficient governance mechanism to ensure development of strong stakeholder network able to create, execute and reinvent shared vision and strategic plan; (2) building knowledge and understanding of local culinary system and practice as step ahead in process of territory interpretation and transformation into the valuable intangible touristic resources; and (3) gastro tourist needs, wishes and ways to engage tourist.

Abstract
Purpose
Looking for ways to gain competitive advantage (CA) is one of the most challenging issues for today's businesses. Although previous research considered several aspects in this regard, the literature has largely overlooked the process of gaining CA via strategic intangibles, regarding business type and context. This paper aims to examine how to gain CA through strategic intangibles such as intellectual capital (IC).
Design/methodology/approach
Building on the concept of IC, and using data gathered from both the manufacturing/service and public/private firms, the authors tested a moderated mediation model to determine if the effect of IC on CA was conditioned on business type, competitive intensity and managerial support.
Findings
Among the factors in the relationship between IC and CA, the results discovered the role of business intelligence (BIN) and brand image (IM), as two key mediators. Furthermore, it was revealed that managerial support and competitive intensity moderate the relationship between IC, the mediators and CA. Finally, the authors provide academics and practitioners with some implications.
Originality/value
Previous research did not fully address the aforementioned antecedents (i.e., IC, BIN and IM) toward CA in a comprehensive model. Developing the path toward CA by focusing on the role of intangibles, the authors proposed a moderated mediation model, which has hitherto received scant attention in the field of competition.
