Abstract

Purpose

This paper aims to present a nonlocal gradient plasticity damage model to demonstrate the crack pattern of a body, in an elastic and plastic state, in terms of damage law. The main objective of this paper is to reconsider the nonlocal theory by including the material in-homogeneity caused by damage and plasticity. The nonlocal nature of the strain field provides a regularization to overcome the analytical and computational problems induced by softening constitutive laws. Such an approach requires C1 continuous approximation. This is achieved by using an isogeometric approximation (IGA). Numerical examples in one and two dimensions are presented.

Design/methodology/approach

In this work, the authors propose a nonlocal elastic plastic damage model. The nonlocal nature of the strain field provides a regularization to overcome the analytical and computational problems induced by softening constitutive laws. An additive decomposition of strains in to elastic and inelastic or plastic part is considered. To obtain stable damage, a higher gradient order is considered for an integral equation, which is obtained by the Taylor series expansion of the local inelastic strain around the point under consideration. The higher-order continuity of nonuniform rational B-splines (NURBS) functions used in isogeometric analysis are adopted here to implement in a numerical scheme. To demonstrate the validity of the proposed model, numerical examples in one and two dimensions are presented.

Findings

The proposed nonlocal elastic plastic damage model is able to predict the damage in an accurate manner. The numerical results are mesh independent. The nonlocal terms add a regularization to the model especially for strain softening type of materials. The consideration of nonlocality in inelastic strains is more meaningful to the physics of damage. The use of IGA framework and NURBS basis functions add to the nonlocal nature in approximations of the field variables.

Research limitations/implications

The method can be extended to 3D. The model does not consider the effect of temperature and the dissipation of energy due to temperature. The method needs to be implemented for more real practical problems and compare with experimental work. This is an ongoing work.

Practical implications

The nonlocal models are suitable for predicting damage in quasi brittle materials. The use of elastic plastic theories allows to capture the inelastic deformations more accurately.

Social implications

The nonlocal models are suitable for predicting damage in quasi brittle materials. The use of elastic plastic theories allows to capture the inelastic deformations more accurately.

Originality/value

The present work includes the formulation and implementation of a nonlocal damage plasticity model using an isogeometric discretization, which is the novel contribution of this paper. An implicit gradient enhancement is considered to the inelastic strain. During inelastic deformations, the proposed strain tensor partitioning allows the use of a distinct potential surface and distinct failure criterion for both damage and plasticity models. The use of NURBS basis functions adds to more nonlocality in the approximation.

Abstract

Subject area

The subject area of the case study is strategic management with emphasis in stakeholder satisfaction and added value and business performance.

Study level/applicability

The case study illustrates the challenges of business dynamics in an emerging market. It is applicable, especially, for undergraduate and graduate students in management studies.

Case overview

The case of LPCI Insurance Company in Mexico illustrates the challenges that firms face when doing business in an unstable, rapidly changing environment. Conflict-affected areas pose significant threats and opportunities for firms; it is, however, up to the firm to decide whether to avoid change and risk or to design and execute effective strategies to tackle such external issues. The case has been developed in a narrative way as to demonstrate the intricacies of internal incidents and board meeting discussions, which lead to strategic planning and decision-making.

Expected learning

outcomes It is expected that students enhance their awareness of businesses’ role in the protection of Human Rights as a key factor in their engagement in corporate social responsibility and achievement of objectives. It is expected that students also increase their awareness of the implications of operating in a conflict-affected area in emerging markets. Also, it is expected that students learn that doing business effectively requires a holistic approach to business dynamics.

Abstract

Purpose

The purpose of this paper is to propose an implementation model for enterprise resource planning (ERP) based on resource-based view, and using the dynamic capability theory as its theoretical foundation. This model includes: the establishment of the objectives of the implementation, an assessment of the available resources and the scope of the implementation, the redesign/integration and organizational learning during the process, the implementation of the system, and the measurement and evaluation of its performance.

Design/methodology/approach

An integrated circuits design company in Taiwan was used in a case study to examine the validity of the proposed model.

Findings

When the proposed ERP implementation model was applied in this study, the results show that organizational coordination, system-process redesign and integration, and organizational learning are the critical strategies for enterprises, in order to reduce the risks during the implementation of ERP projects.

Practical implications

This model can help enterprises recognize the resources needed when implementing an ERP. In addition, they need to consider the reliability of these resources, as this will increase the efficiency of the implementation, and thus the probability of success.

Originality/value

Studies of past models in the implementation of ERP have been conducted in various industries. There is a need for further studies that evaluate the different concepts in terms of the effectiveness of specific methods, in order to enhance the probability of successfully implementing a dynamic system. This paper is one of the first to explain how an enterprise can implement an ERP that is based on the theory of dynamic capabilities. The case study illustrates the important, critical success factors.

Abstract

Purpose

Patronage of local footwear have not been encouraging in Nigeria despite recent investments. The purpose of the study is to evaluate celebrity endorsement and customer patronage of small and medium-scale enterprises (SMEs) products in African context, with focus on trustworthiness, expertise, attractiveness, respect and similarity (TEARS) model.

Design/methodology/approach

The research was designed as a descriptive survey. An online structured questionnaire was applied for data collection. Cronbach Alpha and content validity were used for reliability and validity, respectively. TEARS model was used to ascertain key dimensions, and Pearson correlation coefficient and logistic regression were applied into the analysis.

Findings

The findings reveal that celebrity endorsement is not associated with patronage of local footwears, though TEARS model analysis indicates the direction of consumers rating on celebrity endorsement. Factors such as recommendation and quality impact the consumer willingness to buy local footwear.

Research limitations/implications

The small sample size calls for caution in generalization.

Practical implications

The study suggests that although the TEARs model is viable, all the dimensions are mutually exclusive. However, this depends on the characteristics of the brand. In driving patronage, managers must pay attention to personal and non-personal cues such as price, quality and source of information about their brand.

Originality/value

The originality is buttressed from the value it provides for local product production and patronage. The significant factors are indicated as key to addressing low patronage.

Abstract

Purpose

This conceptual paper aims to contribute to the growing literature around the “politics of heritage” by focusing on India which has a multifaceted society with several layers of religious culture and history.

Design/methodology/approach

The work is based on an extensive review of the literature and philosophical discussions relating to the politics of heritage tourism and the political dimensions of nationalism and ethnicity from an interdisciplinary perspective.

Findings

The main purpose of this conceptual paper is to develop hypotheses. Hence, the study asks: How does postcolonial India reconstruct its past and how are religions represented as part of the national image and for the purpose of tourism promotion? How tourism and religious heritage support a broader secular dreamscape of harmonious cultural nationalism in India? Considering all allegations for supporting the Hindutva movement (who considers Hinduism to be the source of India’s “essential” identity and believes it alone can provide national cohesiveness) by the ruling Bharatiya Janata Party (BJP) government in India, it is worth examining if there are any subtle changes to the tourism agenda created by the new government and the ambivalence surrounding it. Is there any place for the “foreigners” (Muslims and Christians) in Hindutva political ideology? Future scholars can analyze how tourism promotional material represents three major religions in the country by the current Indian Government (i.e. BJP) in its official tourism website: www.incredibleindia.org. This will take “politics of heritage” studies to a different trajectory, as analysis of web media has emerged as a critical medium in understanding numerous social processes.

Research limitations/implications

The paper draws on a wide range of seminal work by scholars of nationalism and ethnicity over the past few decades, but it cannot be comprehensive.

Originality/value

The paper’s originality lies in its novel approach to an understudied aspect in tourism studies (i.e. politics of heritage) and providing suggestions for future research.

Abstract

This chapter enquires into the political struggles that have led to the gradual institutionalization of neoliberal policies in India. As India witnessed a surge in democratization since the 1980s, the state sought to implement a policy regime of privatization and liberalization, albeit with mixed success. This chapter's contribution is to focus on the party-movement relationships that were integral to establishing this new political economy. To this end the chapter undertakes an “event-centered” analysis of the failed authoritarian interlude of 1975–1977 (the Emergency) and its aftermath. Subsequent to this turning point, the chapter argues the two key political parties – the Bharatiya Janata Party (BJP) and Congress – converged upon and shaped support for a neoliberal project. In particular, the chapter traces the mechanisms by which the BJP seized the political opportunity opened during the wave of democratization that occurred from the Emergency period onward, gradually constructing a political bloc in opposition to socialism. Together with Congress Party policies “from above,” the populist mobilization led by the Hindu Right sought to embed neoliberalism by eroding the disciplinary power of the middle classes. In making this argument, the chapter offers a theory of neoliberalism as a political project that, even as it is led by particular agents such as sections of the capitalist class, technocrats, and/or organized global interests, nevertheless must be embedded through democratic processes.

Abstract

Purpose

The paper aims to show how Latin American corporate executives are faced with a serious problem, low trust and peer confidence. The factors of criticism in the workplace, increased corporate controls, and growing expectations for improved performance and accountability, have accompanied this decline in trust. Traditional approaches to corporate governance, epitomized by organizational behavior theories, have focused on short‐term profits and organizational systems, which fail to achieve desired results. This paper presents the analysis of behavioral dimensions of cross‐cultural team performance in corporate environment in Mexico.

Design/methodology/approach

This paper is based on a literature review of previous research contributions focused on the managers of multinational companies operating in Latin American countries in a cross‐cultural environment. The success of the corporate ventures in Mexico has been evaluated from the perspectives of economic and relational attributes. The discussion in the study revealed that the degree of fit between a corporate parent and venture affects the success of the venture.

Findings

The paper finds that corporate venturing as a strategy for international business development has become significant in view of the process of globalization resulting in the free trade and business development opportunities for multinational companies. The success is associated with high levels of commitment, competitive skills and dynamics in functional management of the venture. In the study the variables of economic and relational dimensions of external and internal fit have shown greater association with venture success. It has also been found that ventures opt for greater autonomy and less economic dependency with their parent ventures for leading success and this finding makes intuitive sense.

Practical implications

The paper shows that the success in corporate venturing is associated with high levels of commitment, trust, group dynamics and skills in functional management of the venture. The discussions in the paper offer analytical insights for the managers to develop an operational balance in the team to achieve higher performance.

Originality/value

The thesis of the paper is developed around the issues of the cross‐cultural variables affecting workplace environment in reference to trust, team work and gender sensitivity required for achieving efficiency in a business ventures. The paper explores and maps the symbiosis between the cognitive drivers of team member personality and organizational work culture.

Abstract

Purpose

The purpose of this paper is to present the managerial perspectives of building, nurturing and evaluating sales teams in Mexico. This study discusses the impact of sales team design in reference to the underlying rationale of management control and team coordination as indicators of performance and sales unit effectiveness.

Design/methodology/approach

The major focus of the study is to discuss the impact of sales team design and task coordination as predictors of effectiveness of sales unit performance. A sample of 258 respondents has been covered under the study, categorizing them in equal proportion into three broad areas,: type of sales team, type of product market, and type of sales operations. Four industrial streams in sales were covered while selecting the sample respondents: consumer goods, consumer durables, industrial products, and consumer services.

Findings

The study reveals the balance between team designing and team coordination in performing sales. Work environment is largely governed by team coordination effects for the salespeople. Sales team‐building process has a substantial effect on sales organization effectiveness both directly and indirectly through its relationship with salespeople's behavioral performance.

Practical implications

The results of this study reveal that team performance largely depends on the effectiveness of team coordination, leadership and performance control through behavioral attributes. Sales managers may implement such controls effectively by establishing coordination, training, and feedback process rather than imposing command and control policy.

Originality/value

The thesis of the paper is developed around issues of the cross‐cultural variables and team management affecting workplace environment. The paper explores and maps the symbiosis between cognitive drivers of team members and team culture in performing the tasks.

Abstract

Purpose

The purpose of this paper is to provide a framework for team selling to sports firms that can be used to more effectively select members for sales and CRM teams and improve the performance of teams in attracting and retaining premium seating customers.

Design/methodology/approach

The paper provides a two‐stage framework based on the personal selling process and the activities that support CRM programs. Recommendations are guided by the sport marketing and team selling literature streams and by best practices in sport marketing.

Findings

The paper recommends the formation of two teams (personal selling and CRM) during the customer relationship cycle and provides guidelines for team member selection based on the critical activities that occur during the personal selling and CRM processes. Key success factors are provided, including the establishment of a customer‐focused organization and effective communication practices among team members and between selling teams.

Originality/value

Although the use of selling teams is gaining popularity in several industries, the broader sales literature lacks research that can support the development and effective management of selling teams. Within the sport marketing literature, there is no research on selling teams. The main academic contribution of the paper is the cross‐disciplinary merging of existing team selling research in the sales literature with current research and industry information on marketing and sales by sport organizations (luxury suite sales). For the practitioner, the framework provides guidance on effective team member selection and best practices for the effective management of selling teams.

Abstract

Purpose

This paper aims to propose a dynamic and holistic framework that combines the brand portfolio audit with the brand architecture redesign.

Design/methodology/approach

Depicting from an extensive review on the frameworks of brand audit and brand architecture, a dynamic approach to brand portfolio audit and brand architecture strategy was developed, and later applied and tested in three B2B and B2C companies.

Findings

The paper suggests an eight-step framework to guide practitioners when auditing a specific brand portfolio and designing a revised brand architecture strategy. Additionally, a Brand Audit Scorecard was developed to enable and sustain brand portfolio audits, divided into three dimensions (brand equity, brand contribution and strategic options).

Research limitations/implications

Further research should aim at testing the proposed framework in different types of companies and countries.

Originality/value

This paper contributes to the brand audit and brand architecture literature by proposing a holistic framework that is not static.
