Abstract
The frictional behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity as well as the environmental temperature. Based on a great number of experiments of rubber blocks moving on concrete and ice surfaces, a friction law for 3D contact analyses is presented in this paper. It is characterized by the dependency on the contact pressure, sliding velocity and the environmental temperature. The identification and correction of the parameters of this friction law were done by means of a least‐square method followed by re‐analyses of the respective experiments. Several examples are given in a numerical investigation of the frictional behavior of rubber materials.

Abstract
Purpose
Business models are increasingly recognized as a concept to support innovation in organizations. The implementation and operation of a new or altered business model involves the (re-)design of an organization's business processes and their successful execution. This study reviews and synthesizes the existing body of literature to guide organizations in systematically moving from a business model design to the implementation and operation of the business model through their underlying business processes.
Design/methodology/approach
A systematic literature review of the methods that bridge business models and business processes is performed. The selected 34 studies are classified according to the method's characteristics and the support in the design, implementation and operation of business models.
Findings
The results of the systematic review provide an overview of existing methods that organizations can adopt when moving from business model design into the implementation and operation of their business model using processes.
Originality/value
This work provides a comprehensive overview and detailed insight into the existing methods that align business models and business processes. It increases the understanding on how these two concepts can be synthesized to support more effective digital innovation in organizations. Based on the review results, knowledge gaps are identified and an agenda for future research bridging the fields of business models and business processes is proposed.

Abstract
Purpose
This study aims to investigate the efficacy of the supply network approach in bolstering supply chain resilience amidst escalating global uncertainty. With enterprises worldwide facing increasing threats that disrupt supply chains, this research explores how firms enhance supply network resilience during crises.
Design/methodology/approach
Using a multi-case study design, this research thoroughly examines interactions within firms’ supply networks to uncover new insights on supply network approach and how firms enhance supply network resilience against global uncertainty. The selection of cases was methodologically aligned to represent diverse industries and geographical locations to ensure a comprehensive analysis.
Findings
This study’s findings reveal how firms develop supply network resilience during global crises. The supply network perspective provides a deeper understanding of how firms manage supply chain interactions, interdependencies and strategic positions to survive and thrive during crises. The conceptual framework developed here provides insights that can foster improved coordination and facilitate effective temporary organising. The framework highlights the need for firms to proactively seize opportunities and mitigate risks within their global supply chains during crises to boost overall resilience.
Originality/value
Offering novel insights into the domain of supply chain networks, this study underscores novel perspectives of the supply network approach when firms develop supply chain resilience during global crises. Highlighting the adaptive responses of firms that integrate these approaches enriches the understanding of strategic manoeuvres firms can use to navigate global uncertainty and secure supply chain continuity.

Abstract
Purpose
Organisations working with children have acknowledged that unaccompanied refugee minors (URM) across Europe are exposed to environments and situations that put them at risk for becoming addicted to drugs or becoming involved in crime. The purpose of this paper is to study an examination of existing international research concerning URM and of whether, and if so how, issues relating to drug use and criminality among these children are discussed in the international literature.
Design/methodology/approach
A literature review was conducted using PsycINFO, PubMed, Sociological abstracts and ERIC databases, which together cover the social and behavioural science and also medicine.
Findings
Findings from the present review show that the issues of drug abuse and criminality among URM are rarely acknowledged in the international research literature. When the occurrence of substance abuse and/or criminality is discussed, it is often in relation to mental health problems and in terms of self-medication, i.e. that alcohol or drugs are used by the URM to cope with painful experiences or mental health problems, and also with the challenges of integrating into a new society, difficulties finding work, unsuitable living conditions and a lack of social support.
Originality/value
This review shows that several researchers have emphasised that untreated mental health problems, stressful living conditions and a lack of support and control might put these children at risk for substance abuse and criminality, and this suggests a need for further research in this area.

Abstract
Prior to conducting business via the Web, business partners agree on the business processes they are able to support. In ebXML, the choreography of these business processes is described as an instance of the so‐called business process specification schema (BPSS). For execution purposes the BPSS must be defined in the exact business context of the partnership. Reference models for B2B processes developed by standard organizations usually span over multiple business contexts to avoid a multitude of similar processes. In this paper we present how business collaboration models following the UN/CEFACT Modeling Methodology (UMM) are expressed in ebXML BPSS. To allow a mapping from multi‐context business collaboration models to a context‐specific choreography in ebXML BPSS we extend UMM to capture constraints for different business contexts

Abstract
Purpose
The previous generations of implemented B2B e‐commerce hub solutions (e‐Marketplaces) did not successfully fulfil the requirements of buyers and suppliers (“Participants”) in different business domains to carry out their daily business and online commercial transactions with one another because of their inappropriateness, and lack of flexibility. The limitations of these provided solutions came from a lot of architectural and technological challenges in the provided technical architectures that were used to build these solutions. This research aims to provide a proposed architecture to build integrated B2B e‐Commerce hub solutions. It also aims to make use of bottom‐up/top‐down approaches to building an integrated solution and to resolve the reasons for the failure of previous generations of B2B e‐commerce hubs.
Design/methodology/approach
The research uses the EDI reference model, which is provided by the ISO organization to survey and analyze the challenges of previous generations of B2B e‐Commerce hubs solutions and their architectures. The study develops a proposed solution architecture based on the recent approaches to building IOSs to build a B2B e‐commerce hub solution architecture that can be used to implement vertical B2B e‐commerce hubs (vertical e‐Marketplaces). The paper assesses the capabilities of the proposed solution architecture for building vertical B2B e‐Marketplaces by applying the proposed architecture to the building of a vertical B2B e‐Marketplace for the oil and gas sector in Egypt.
Findings
Previous B2B e‐Commerce hub initiatives failed to extend their products and services to their “Participants”, and required substantial investment and effort from each “Participant” to join such a B2B e‐Commerce hub. The failure of these IOS projects lies in their inability to integrate B2B e‐Commerce networks based on IOS and consequently, they supported very few partners and “Participants”. These IOS approaches did not resolve the existing challenges of B2B e‐Commerce hubs, especially in the realm of interoperability.
Originality/value
The main contribution of the proposed architecture comes from the creation of a clear automatic path between a business requirements layer and a technology layer by combining both Service Oriented Architecture and management requirements in a single framework to provide dynamic products and flexible services. It provides a complete Multi Channel Framework to resolve the interoperability challenges.

Abstract
At the nexus of mindfulness and parenting lies the fusion of two influential yet contradictory epistemologies, the Eastern contemplative practices with the Western parenting research. Mindful parenting is a parenting style, which has grown in popularity in recent times to support parents during pregnancy, birth and beyond. The current study is the third stage of a mixed methods study on mindful parenting. The first stage of the study design conducted a systematic review of mindful parenting. The second stage summarized the change processes identified in the systematic review. The aim of this pilot study is to clarify four clinicians’ perceptions of cognitive change processes associated with mindful parenting, particularly how theory is translated to practice. Interpretative Phenomenological Analysis (IPA) was used to analyze semi-structured interviews. The six higher-order change processes were conceptualized as an anchor. Cognitive processes included intention, attention, attitude, and reflective functioning. Given its methodological limitations, the next future work needs is to survey a large sample of both clinicians and parents to verify the model. This paper makes an important contribution to the development of a more comprehensive theoretical model of mindful parenting.
