Abstract
This paper shows a generalization of the classic isotropic plasticity theory to be applied to orthotropic or anisotropic materials. This approach assumes the existence of a real anisotropic space, and other fictitious isotropic space where a mapped fictitious problem is solved. Both spaces are related by means of a linear transformation using a fourth order transformation tensor that contains all the information concerning the real anisotropic material. The paper describes the basis of the spaces transformation proposed and the expressions of the resulting secant and tangent constitutive equations. Also details of the numerical integration of the constitutive equation are provided. Examples of application showing the good performance of the model for analysis of orthotropic materials and fibre‐reinforced composites are given.

Abstract
Purpose
The expanded use of mobile devices for shopping has made mobile showrooming a frequent practice among omnichannel shoppers. This paper aims to shed light on the role of mobile dependency and uncertainty reduction strategies together with the motivation of getting the best value for money in showrooming behaviours and user-generated content (UGC) creation.
Design/methodology/approach
Data were collected by means of a questionnaire answered by 659 shoppers in two product categories: clothing and consumer electronics. The research model was tested through partial least squares.
Findings
The results suggest that mobile showrooming attitude is positively affected by mobile dependency, value consciousness and need for touch, and negatively by perceived risk of mobile shopping. The results also reveal how UGC is created by showroomers and suggest this behaviour is linked to mobile dependency in the clothing category.
Research limitations/implications
All the individuals in the sample had some experience in showrooming, which could affect the results regarding showrooming attitude and intentions. Future research should consider the role of experience and also validate the results across a larger number of product categories.
Practical implications
Mobile showrooming is a challenge for multichannel retailers. This paper reveals certain ways in which multichannel retailers could deal with showroomers as potential customers.
Originality/value
This study is the first to analyse the role of mobile dependency in showrooming and the chain of effects towards mobile showrooming attitude, behaviour and UGC creation in two different product categories.

Abstract
Purpose
The purpose of this paper is to investigate the effects of multichannel integration (MCI) on customer loyalty. The specific objectives are to provide an appropriate reliable measure of the construct, and to analyse the impact of MCI on offline and online loyalty, both directly and by mediation of customer satisfaction.
Design/methodology/approach
The paper focusses on the retail apparel sector of Spain and the UK. The authors applied a scale development process and tested the model with data of 761 multichannel apparel shoppers. The proposed theoretical model was estimated through EQS 6.1 and a mediation test was calculated.
Findings
The findings show, first, that the construct of channel integration has two dimensions: reciprocity, which refers to the possibility of crossing the channels while shopping, and coordination, which refers to the alignment of offline and online offers. Second, that MCI affects positively both offline and online loyalty both directly and through satisfaction, which partially mediates the relationship.
Research limitations/implications
Culture might play a moderating role in the relationships found that are not analysed.
Practical implications
The findings have implications for the managers of multichannel retail companies as they help to understand the benefits of channel integration in creating a loyal customer base both online and offline.
Originality/value
This paper contributes to the literature on multichannel retailing in two main ways: first, by developing a scale to measure MCI, and second, by demonstrating that MCI has strong effects on customer satisfaction and loyalty.

Abstract
Purpose
The purpose of this paper is to investigate the factors that determine two forms of crowdfunding campaign success: success in securing the necessary financial resources and personal success in terms of the entrepreneur’s satisfaction. Specifically, it studies factors linked to the relationship between entrepreneurs and funders (co-creation and feedback) and factors linked to the campaign’s content (dimensions of corporate social responsibility (CSR)).
Design/methodology/approach
An empirical study of 52 crowdfunding entrepreneurs was conducted. Data were gathered using a structured questionnaire. Fuzzy-set qualitative comparative analysis was performed.
Findings
For financial and personal success, all factors, except the social dimension of CSR, are necessary conditions. Two configurations are sufficient for entrepreneurs to achieve financial success. The first configuration that is sufficient for personal success is the same as the first configuration for financial success. The second configuration for personal success is similar to the second configuration for financial success, except that it also includes financial success itself.
Research limitations/implications
Entrepreneurs should invest in CSR and seek to improve the quality of their relationships with their funders. Crowdfunding platforms should design and manage co-creation and feedback tools that are capable of providing deep knowledge of users’ opinions and concerns whilst generating value. The limitations of this study are that only the reward-based crowdfunding model was considered, and the data covered just two platforms.
Originality/value
This study contributes to the literature by presenting empirical analysis of the factors that influence financial success and personal success in reward-based crowdfunding. It examines aspects that strictly refer to the content of the project and aspects that refer to the entrepreneur–funder relationship. Specifically, the roles of the four dimensions of CSR were considered. Moreover, the fsQCA method provides a fresh approach to research in this area.

Abstract
Purpose
Today’s society interest in mobile photography drives consumers’ and brands’ growing usage of Instagram. This paper aims to address the consequences of excessive use of Instagram on the negative feeling of losing information when not connected and the emotional fatigue resulting from an overcharge with new information. The mediating role of addiction between Instagram overuse and the two outcomes is also analyzed.
Design/methodology/approach
Data from 342 active Instagram users were used to test the proposed model, applying the partial least square equation modeling method (SmartPLS 3).
Findings
Addiction partially mediates the impact of overuse on emotional fatigue and instastress. Addiction to Instagram was mainly due to respondents’ lack of control over the time spent on it resulting in incapability to reduce its usage.
Social implications
Social networking site managers, educators, families and public institutions should promote an adequate use of Instagram, making users (especially the young) aware of the potential threats of its excessive usage. The control on the amount of time devoted to Instagram is a key factor for detaining overuse and addiction, as well as avoiding the negative outcomes analyzed in this research.
Originality/value
The findings contribute to the extant knowledge on the negative side of the digitization of the individual, as little is known about it to the best of the authors’ knowledge.
Propósito
La presente investigación aborda las consecuencias del uso excesivo de Instagram relacionadas con el sentimiento negativo de pérdida de información, cuando no se está conectado, y la fatiga emocional derivada de la sobrecarga de información. El estudio también analiza el papel mediador de la adicción entre el uso excesivo de Instagram y ambas consecuencias.
Diseño/metodología/enfoque
Para testar el modelo propuesto se utilizó información de 342 usuarios activos de Instagram, aplicándose el método de ecuaciones estructurales por mínimos cuadrados parciales (SmartPLS 3).
Hallazgos
La adicción media parcialmente el impacto que el uso excesivo de Instagram tiene sobre (i) la fatiga emocional y (ii) el Instastress. La adicción a Instagram se deriva principalmente de la falta de control del tiempo invertido en su uso, lo que da como resultado su incapacidad para reducir dicho uso.
Implicaciones sociales
Los responsables de los medios sociales, los educadores, las familias y las instituciones públicas deberían promover un uso adecuado de Instagram, haciendo que los usuarios (especialmente los más jóvenes) sean conscientes de las amenazas potenciales de su uso excesivo. El control sobre la cantidad de tiempo dedicado a Instagram es un factor clave para detener el uso excesivo y la adicción, así como para evitar los resultados negativos analizados en esta investigación.
Originalidad/valor
Los resultados contribuyen a ampliar el conocimiento sobre el lado negativo de la digitalización del individuo, dada la escasa literatura al respecto.
Palabras claves
Adicción, Uso excesivo, Instastress, Fatiga emocional, Redes sociales, Instagram

Abstract
The paper describes the application of the simple rotation‐free basic shell triangle (BST) to the non‐linear analysis of shell structures using an explicit dynamic formulation. The derivation of the BST element involving translational degrees of freedom only using a combined finite element–finite volume formulation is briefly presented. Details of the treatment of geometrical and material non linearities for the dynamic solution using an updated Lagrangian description and an hypoelastic constitutive law are given. The efficiency of the BST element for the non linear transient analysis of shells using an explicit dynamic integration scheme is shown in a number of examples of application including problems with frictional contact situations.

Abstract
Purpose
Drawing on the resource-based view (RBV) and knowledge-based view (KBV) theories, this study contributes to deepen the knowledge that corporate social responsibility (CSR) exerts on firms' innovation, considering the role played by cooperation. The research also seeks to ascertain the factors that influence the development of business cooperation.
Design/methodology/approach
The database used is the Community Innovation Survey (CIS, 2014) applied in the European Union (EU) during the time period 2012–2014. A sample of 7083 Portuguese firms were analyzed through the partial least squares structural equation modeling (PLS-SEM).
Findings
The results suggest that CSR positively relates with firms' innovation, and business cooperation partially mediates this relationship. The outcomes also reveal that investing in certain types of innovation activities increases the firms' willingness to cooperate.
Originality/value
The findings contribute to encourage an open innovation strategy as an easy and effective way to cope with rapid trends and changes, since it demonstrates the complementary between innovation and cooperation, as sources of value creation. From a triple bottom line (TBL) perspective, it also highlights that CSR must include social, economic and environmental initiatives, and should be a part of the firms' innovation strategy. As a result, managers who intend to contribute for society in the long term should plan, monitor and manage all CSR dimensions.

Abstract
The importance of tourism in Spain has not been accompanied by variety of marketing studies and research. In this paper the two great factors contributing to the slow development of tourism marketing in Spain are identified. On the one hand the youth of the discipline at international level and especially at national level. Secondly, the evolution of the market itself and the passive orientation of marketing. Next the contributions emanating from Spanish tourism marketing circles are reviewed and analysed in terms of their connection with lines of research emanating from the international literature. Finally, future research perspectives for tourism marketing are indicated.

Abstract
Purpose
This paper studies the nonlinear dynamics of membrane structure considering wrinkling effect. The coupling between wrinkles and vibration is investigated elaborately, and new insight on the dynamics of wrinkled membrane is unveiled.
Design/methodology/approach
Based on the stability theory of plates and shells, the wrinkling model of the membrane structure is established. Considering the effects of wrinkling and nonlinearity, the dynamic response is calculated with NewMark method.
Findings
Wrinkling will impact the dynamics of the membrane structure significantly for asymmetrical tension loading cases, dynamic response of the wrinkled membrane structure can be classified into three categories: when the vibration is small, the dynamics of the wrinkled membrane structure will behave linearly, and the wrinkles will only affect the dynamic properties as initial conditions; when the vibration is relatively large, the wrinkles will interact with the vibration during the dynamic process, and the dynamics of the structure shows very complex features; when the vibration is large enough, the dynamics will be dominated by the geometric nonlinearity of large-amplitude vibration.
Originality/value
In the previous works on dynamics of wrinkled membrane structure, only the vibration modes have been studied, which means all those investigations are confined with linear vibration; little research has been conducted on the nonlinear dynamics of wrinkled membrane structure. In view of this, this paper presents an investigation of dynamic properties of membrane structure considering the wrinkling and geometric nonlinear effects. This research work presents some novel discoveries on the nonlinear dynamics of wrinkled membrane.

Abstract
The paper describes the extension of the critical displacement method (CDM), presented by Oñate and Matias in 1996, to the instability analysis of structures with non‐linear material behaviour using a simple damage model. The extended CDM is useful to detect instability points using a prediction of the critical displacement field and a secant load‐displacement relationship accounting for material non‐linearities. Examples of application of CDM to the instability analysis of structures using bar and solid finite elements are presented.
