Abstract

Purpose

Friction stir welding (FSW) is simple, clean and cost effective joining technology which allows high‐quality joining of materials that have been traditionally troublesome to weld conventionally without distortion, cracks or voids such as high‐strength aluminium alloys. Since FSW has been identified as “key technology” for primary aerospace structures, the recent FAR regulations for damage tolerance and fatigue evaluations of aircraft structures require fatigue life predictions for this specific joint type also in the presence of corrosion. The purpose of this paper is to give an overview of the prediction of small coupon fatigue lives of thin section friction stir welded butt and T‐joints.

Design/methodology/approach

Particularly, as a special application, widespread fracture mechanics software will be used to predict the fatigue life of FSW joints and to obtain SN curves. The engineering approach will start from an easy definition of the damage affecting the fatigue life of any of the previously mentioned cases (inclusions, tool markings, corrosion pits) and will move through affordable fracture mechanics solutions. Particularly, a first step in predicting the fatigue life of complex friction stir welded structures will be taken by combining the FEM code with the fracture mechanics software in the prediction of the FSW T‐joints.

Findings

The calculations are in very good agreement with the experimental results once the following basic assumptions are done: the welded material is treated as base material; particle inclusions and welding imperfections are treated as initial flaws while predicting the life of polished and un‐polished (including the T‐joints) FSW material, respectively, and the entire fatigue life was comprised of crack propagation; pitting and inter‐granular corrosion are treated as a single corrosion damage source and the model surface crack comprehends this damage; and the several corrosion‐damaged areas of the specimen surface are simulated with a single semi elliptical surface crack having the dimensions of the deepest and the widest corrosion damage area.

Originality/value

A simple engineering approach which is based on a relatively solid background and which is checked against fatigue test data for various FSW test specimens was developed: it may provide a practical and reliable basis for the analysis of fatigue tests of integral structures in the presence of corrosion attack, by using widespread fracture mechanics principles.

Abstract

Purpose

This study aims to increase the understanding of the drivers of mobile shopping, by analyzing when and how two personality traits – value consciousness and shopping enjoyment – impact mobile shopping intention through usefulness and ease-of-use perceptions.

Design/methodology/approach

To test the conditioned indirect effects, path analysis is used.

Findings

The results indicate that both consumers’ value consciousness and shopping enjoyment have a positive indirect effect on mobile shopping intention. However, shopping enjoyment is related only through usefulness, whereas value consciousness is related via both usefulness and ease of use. The results also suggest the need to consider boundary conditions when examining the impact of personality traits.

Practical implications

Mobile retailers need to conduct market segmentation based on users’ personalities when trying to increase their customer base.

Originality/value

Despite the relevance of personality traits on individual behavior, studies on the effects that different aspects of personality have on the participation of individuals in mobile commerce are very scarce and show inconsistent results regarding their impact. Thus, this study tries to contribute to the mobile commerce research by analyzing the interplay between two customer characteristics and two mediating variables: ease-of-use and usefulness perceptions.

Propósito

Esta investigación busca aumentar la comprensión de los antecedentes de las compras móviles, analizando cuándo y cómo dos rasgos de personalidad – conciencia de valor y disfrute por la compra – afectan a la intención de compra móvil a través de las percepciones de utilidad y facilidad de uso.

Diseño/metodología/enfoque

Para comprobar los efectos indirectos condicionados propuestos se emplea un análisis path.

Hallazgos

Los resultados indican que tanto la conciencia de valor como el disfrute por la compra de los consumidores tienen un efecto indirecto positivo en la intención de compra móvil. Sin embargo, el disfrute por la compra se relaciona sólo a través de la utilidad, mientras que la conciencia de valor se relaciona tanto a través de la utilidad como de la facilidad de uso. Los resultados también sugieren la necesidad de considerar factores moderadores al examinar el impacto de los rasgos de personalidad.

Implicaciones para la gestión

Los minoristas a través del móvil que quieran aumentar su base de clientes necesitan segmentar el mercado en base a la personalidad de los usuarios.

Originalidad/valor

A pesar de la relevancia que tienen los rasgos de personalidad en el comportamiento de los individuos, los estudios sobre los efectos de distintos aspectos de la personalidad sobre la participación de los individuos en el comercio móvil son muy escasos y muestran resultados inconsistentes. Así, este estudio intenta contribuir a la investigación sobre comercio móvil analizando la relación entre dos características del consumidor y dos variables mediadoras: las percepciones de facilidad de uso y utilidad.

Abstract

Purpose

This study aims to center on understanding how stakeholder engagement processes improve online child protection in telecom companies. The literature review and findings shed light on the management of networks to identify, prevent and mitigate the adverse impacts of information and communication technologies (ICTs)[1] and to find opportunities in terms of new policies and services development.

Design/methodology/approach

Three multinational telecom companies were analyzed with a qualitative focus combining three research tools: the analysis of 81 corporate reports, self-administered questionnaires and semi-structured interviews.

Findings

Firms establish a collaborative network with a large number of stakeholders such as public authorities, non-governmental organizations, educational institutions, representatives of families and expert researchers. The outcomes of these networks range from the development of new products and services (filters, child safety software and protection apps) to the co-creation of new corporate policies with a high social impact (self-regulation, sectorial codes, awareness initiatives and reporting).

Practical implications

This study outlines guidelines for the industry in identifying, engaging and making decisions in a collaborative way when managers have to engage with multiple stakeholders regarding child protection. The academic debate and the empirical findings have many practical implications for ICT companies whose users are children and teenagers.

Originality/value

Despite its significance, stakeholder management is underexplored in the literature of protection for young people. The academic field and the professional arena appear to have little to say regarding how executives manage engagement processes.

Abstract

Purpose

The purpose of this paper is to present a model to support governmental local managers in public budget optimization, based on an integration of methods. It was constructed to fill the gap related to weights definition in problematic, commonly performed subjective assessments. This model supports the decision making in budget distribution identifying the importance of sectors in local governments, captured by historical data.

Design/methodology/approach

The model was developed following three steps: the first step included the exploitation of the characteristics of local sectors represented by city departments and the data collection procedure using time series (TS). In the second one, the weights regarding the importance of each city department were calculated by the UTASTAR method and based on historical data from the first step. Finally, an objective function was formulated using linear programming and constraints based on law specifications, and as a result, an optimized projection for public budget distribution was performed.

Findings

The results demonstrated that the model can be more efficient to weights definition, considering the behavior of preferences by historical data and supporting local public resources optimization, also to comply with the legislation, being able to predict or project future values available on the budget.

Research limitations/implications

The theoretical and practical implications are related with a novelty in recognizing the weights for criteria by a historical behavior of preferences. It can be bringing important directions for budget distribution. The main limitation detected in this study was the difficulty to formulate an assessment involving an integrated opinion from local managers and the population.

Practical implications

First of all, with the correct allocation of resources, the government has a greater advantage to capture investments from the negotiation with development entities and banks. Second, an efficient local government management can promote compliance with legislation and more transparent public policies.

Social implications

The correct distribution of resources affects the life quality for citizens, since the government acts as a provider of essential services for the population like education, safety, health, particularly for citizens who depend exclusively on the services offered by the local government. Moreover, it can also affect the environment as resources for garbage collection, disposal services and sanitation and, finally, affect the city development such as infrastructure, taxes, etc.

Originality/value

It might be considered an original contribution mainly by the development of a procedure to capture values for weights by TS and meeting the manager’s requirements, based on analytical, statistical and mathematical tools integrated.

Abstract

Purpose

Today's environment imposes traceability compliance on food firms. Power within the interorganisational relationships in the food supply chain may hinder the integration necessary for that traceability to be effective. The purpose of the present study is to define the configuration of power in food industry‐distribution relationships from the food industry perspective.

Design/methodology/approach

The variables of power configuration considered in this study have been classified as mediated and non‐mediated power sources, in accordance with the criteria used by French and Raven. The Rasch model employed in the treatment of the values given by the food industries to the construct perceived power (mediated and non‐mediated power sources) permit a unidimensional measurement of that construct. Thus, the model estimated using this methodology explains power‐shaping in the food industry‐distribution relationships in the Canary Islands.

Findings

The results obtained are mostly based on the distributors' use of mediated power sources; they describe a situation that does not contribute to a high level of commitment in such relationships, since the negative effects of this type of power do not favour the climate required for the implementation of active traceability.

Research limitations/implications

The data applied in this study were gathered prior to the implementation of traceability as a legal requirement, and consequently it would be advisable and useful to conduct a post‐implementation.

Originality/value

The paper adopts a business management approach, aimed at improving relations in the food supply chain. The methodology employed allows food firms to establish suitable chain integration strategies, facilitating the effective implementation of traceability. The paper presents a conceptual framework and analytical methodology which sustain the present study and subsequent work.

Abstract

Purpose

The purpose of this study is to analyze the perception of accountants in relation to the complexity of accounting for financial instruments and in relation to the disclosure of financial instruments in annual reports. Both aspects are relevant for the external users, and for the firms’ internal management.

Design/methodology/approach

The database comprises questionnaires answered by accountants from Brazil and Chile. Data were analyzed based on reliability statistics and multivariate regression analysis.

Findings

The main results indicate that accountants perceive the accounting for derivatives, hedge accounting, fair value measurement of financial instruments and the respective disclosure of these operations as a complex issue. These findings are interesting considering that there are detailed accounting standards relating to financial instruments.

Research limitations/implications

The results indicate that education and gender affect the perception of complexity about accounting of derivatives.

Practical implications

Findings from this research show that accountants do perceive derivatives as complex items for accounting, particularly accounting for hedges.

Social implications

The results can motivate some initiatives for training activities and for teaching academic content about financial instruments in undergraduate courses.

Originality/value

To the best of the authors’ knowledge, this is the first study that tests some personal characteristics of accountants (namely, professional experience, education and gender), in contrast to their perceptions about complexity of accounting for derivatives.

Abstract

Purpose

The purpose of this paper is to propose a framework for brand meaning co-creation between brands and fans on Facebook.

Design/methodology/approach

A case study methodology was applied. Brand posts in the form of text, pictures, videos and fan comments of three brand pages – Nike Run, Mizuno and Jack Daniel’s – were collected and analyzed in a netnographic manner. Seven influential fans of the Nike Run brand page, who were identified in the data, and one marketing manager of each brand were interviewed.

Findings

This paper shows how brand meanings are orchestrated by brand managers and co-created through a process in which the brand leads the dialog through several types of brand actions. It also shows how fans engage in this dialog through multiple forms of reactions. A brand page’s content should be curated by its manager based on the role of the content on fans’ lives and their potential reactions and not merely on the meanings that the brand desires to communicate.

Research limitations/implications

This paper proposes a conceptual framework for understanding brand meaning co-creation at the micro-level of brand-fans daily interactions. Nevertheless, this study analyzed only three brand pages in two product categories – alcoholic beverages and running. Therefore, the authors do not claim that one can extrapolate from their findings.

Practical implications

The brand meaning co-creation process that is identified here provides a useful frame of reference for brand managers who seek to understand how they can best influence fans to co-create brand meanings in directions that benefit their companies.

Originality/value

This paper evolves with the co-creation of brand meanings literature by proposing a framework of brand meaning co-creation on Facebook. This framework can help brand managers to fine tune their content strategy in social media.
