Abstract

Purpose

The purpose of this paper is to investigate the effects of different shape memory polymer based snap‐fits in terms of disassembly time and reusability.

Design/methodology/approach

In total, six different sets of snap‐fits were designed and manufactured. Each set of snap‐fits was tested ten times in a testing device for disassembly time. The stress caused by training process is simulated and analyzed.

Findings

One of the designs shows shortest average disassembly time, lowest standard deviation, and lowest stress. However, the overall reusability of the snap‐fits is not good enough for industrial use.

Originality/value

The paper tests the Veritex shape memory polymer sheets manufactured by CRG Industries LLC. The reusability has been analyzed based on the stress caused by the training process.

Abstract

Purpose

Impinging jets have been widely studied, and the addition of swirl has been found to be beneficial to heat transfer. As there is no literature on Reynolds-averaged Navier Stokes equations (RANS) nor experimental data of swirling jet flows generated by a rotating pipe, the purpose of this study is to fill such gap by providing results on the performance of this type of design.

Design/methodology/approach

As the flow has a different behaviour at different parts of the design, the same turbulent model cannot be used for the full domain. To overcome this complexity, the simulation is split into two coupled stages. This is an alternative to use the costly Reynold stress model (RSM) for the rotating pipe simulation and the SST k-ω model for the impingement.

Findings

The addition of swirl by means of a rotating pipe with a swirl intensity ranging from 0 up to 0.5 affects the velocity profiles, but has no remarkable effect on the spreading angle. The heat transfer is increased with respect to a non-swirling flow only at short nozzle-to-plate distances H/D < 6, where H is the distance and D is the diameter of the pipe. For the impinging zone, the highest average heat transfer is achieved at H/D = 5 with swirl intensity S = 0.5. This is the highest swirl studied in this work.

Research limitations/implications

High-fidelity simulations or experimental analysis may provide reliable data for higher swirl intensities, which are not covered in this work.

Practical implications

This two-step approach and the data provided is of interest to other related investigations (e.g. using arrays of jets or other surfaces than flat plates).

Originality/value

This paper is the first of its kind RANS simulation of the heat transfer from a flat plate to a swirling impinging jet flow issuing from a rotating pipe. An extensive study of these computational fluid dynamics (CFD) simulations has been carried out with the emphasis of splitting the large domain into two parts to facilitate the use of different turbulent models and periodic boundary conditions for the flow confined in the pipe.

Abstract

Purpose

Pulque is a fundamental piece in the Mexican gastronomy and identifying consumers’ perception could help promote it and generate new opportunities of commercialization. The purpose of this paper is twofold: first, to explore the underlying factors that influence consumers’ perception toward pulque, and second, to identify groups of consumers according to their perception.

Design/methodology/approach

A questionnaire was designed and applied to 220 consumers within points of sales. Exploratory factor analysis (EFA) was undertaken and hierarchical cluster analysis (HCA) was used to identify different groups of consumers.

Findings

By means of EFA three factors were obtained: traditionality, bad reputation of pulquerías and functional beverage. In order to identify different consumption patterns among consumers, HCA was performed and three groups were identified: traditional, neo-consumers and neo-consumers in transition. The groups identified showed significant differences in their perception.

Practical implications

Pulque has recently gained interest in various consumer sectors, mainly among young consumers, who are consuming and promoting the beverage these days. In this sense, the results of this work could be used for its promotion and consumption in order to attract more consumers and make a contribution to the development of local economies.

Originality/value

This is the first work in Mexico to explore the perception of consumers toward pulque: the most important traditional fermented beverage in Central México. Results of this research suggest the appearance of a revaluation process among young consumers, more informed and with greater sensitivity toward traditional Mexican food, particularly in the case of pulque. Likewise, these results could be useful for producers and sellers to carry out commercial strategies and promote the drink.

Abstract

Purpose

This paper aims to determine the effect of a set of factors (attitude toward entrepreneurship, perceived behavioral control or entrepreneurial self-efficacy, previous experience, internal locus of control and entrepreneurial alertness) on the entrepreneurial intentions of Chilean secondary vocational school students.

Design/methodology/approach

An online survey was sent to all secondary-level students from four Chilean vocational schools (3,052 students). A total of 1,644 valid questionnaires were received. The data were analyzed using partial least squares structural equation modeling (PLS-SEM).

Findings

The results show that attitude toward entrepreneurship and perceived behavioral control positively and significantly impact the students’ entrepreneurial intentions, but not the previous experience.

Research limitations/implications

Since this research was carried out in a specific reality, the results may lack generalizability. Also, the proposed model requires further development through the incorporation of other factors. It is then suggested to replicate this study in other countries as well as to incorporate new variables and test new relationships.

Practical implications

Entrepreneurship education programs at the secondary level should emphasize changing/stimulating adolescents’ attitudes toward entrepreneurship as well as improving their confidence in their entrepreneurial abilities.

Originality/value

This is one of the few studies that provide empirical evidence about the determinants of entrepreneurial intentions in adolescents, particularly in Latin America, and with a large sample.

Propósito

El propósito de este estudio es determinar el efecto de un conjunto de factores (actitud hacia el emprendimiento, control conductual percibido o autoeficacia emprendedora, experiencia previa, locus de control interno y alerta emprendedora) sobre las intenciones emprendedoras de estudiantes secundarios técnico-profesionales chilenos.

Diseño/metodología/aproximación

Una encuesta online fue enviada a todos los estudiantes de nivel secundario de cuatro escuelas técnico-profesionales chilenas (3,052 estudiantes). Se recibieron un total de 1,644 cuestionarios válidos. Los datos obtenidos fueron analizados a través de una técnica de modelización de ecuaciones estructurales (PLS-SEM).

Resultados

Los resultados muestran que la actitud y el control conductual percibido impactan positiva y significativamente sobre las intenciones emprendedoras de los estudiantes, no así la experiencia previa.

Limitaciones/implicancias de la investigación

Dado que esta investigación se llevó a cabo en una realidad específica, se debe ser cauteloso a la hora de generalizar sus resultados. Asimismo, el modelo propuesto requiere un mayor desarrollo a través de la incorporación de otras variables. Se sugiere entonces replicar este estudio en otros países, así como incorporar nuevas variables y someter a prueba nuevas relaciones.

Implicancias prácticas

Los programas de educación emprendedora en el nivel secundario debiesen poner énfasis en cambiar/estimular las actitudes hacia el emprendimiento de los adolescentes, así como en mejorar su confianza en sus propias habilidades emprendedoras.

Originalidad/valor

Este es uno de los pocos estudios que aporta evidencia empírica acerca de los determinantes de las intenciones de emprender en adolescentes, particularmente en América Latina y con una muestra amplia.

Abstract

Purpose

The main purpose of this paper is to assess the patterns in the public discourse of successful chief executive officers (CEOs) in terms of performance, with the CEO's strengths and aspects to improve.

Design/methodology/approach

This paper aligns with the literature that appraises CEO public discourse and relevance. From the literature review, the strategic levers in CEO discourse toward high performance are identified. The CEO letters in the period 2017–2019 of the top 25 best performing CEOs (BPCs) according to Harvard Business Review ranking 2019 are qualitatively examined through a multiple close reading analytical technique and multiple correspondence analysis (MCA) is applied to assess the patterns.

Findings

The paper delivers a three-dimensional model representing how the identified strategic levers are articulated by BPCs in the BPC's discourse following diverse patterns. This paper points out BPC's strengths, among them a high level of moral reasoning compared to previous studies and improvable areas such as the extended absence of autocritique at the firm and personal level or the lack of leverage on the need for agility and proactive adaption.

Practical implications

This paper contributes further CEO awareness of the strategic role of the discourse and offers clues to enhance CEO awareness, as well as criteria for boards of directors to appraise CEO discourse.

Originality/value

Adopting a novel approach, this paper addresses the strategic levers triggered by CEOs in their letters from a managerial implication perspective, providing relevant theoretical insight on how they are articulated.

Abstract

Purpose

This work aims to develop a configurational model to explain how relational trust and combinative capability can jointly improve the relationship between innovativeness and firm's performance.

Design/methodology/approach

The empirical study was developed on a sample of 224 companies in the footwear industry in Spain. Hierarchical regression analysis was used to test the hypotheses in order to confirm the proposed configurational model.

Findings

The partial results demonstrate the significant effect of relational trust on the innovativeness-performance relationship but, unexpectedly, reveals the non-significant effect of combinative capability on this relationship. The triple interaction effects model provides new insights into the positive effect of combinative capability on the innovativeness-performance relationship once firms gain relational trust from their contacts.

Research limitations/implications

The cross-sectional nature of the study imposes a limitation on the results. Nevertheless, due to the detailed information required to achieve the aims of the research, a longitudinal study could be excessively complex. In any event, the cross-sectional approach of the study accomplishes the proposed aim.

Practical implications

Managers should involve the employees of the firm in order to improve the effectiveness of continuous innovation, encouraging them to establish trusting relationships with external agents and contributing to combine the relevant external knowledge with the individual and collective knowledge available in the firm.

Originality/value

This work contributes to the existing literature with a more complete picture of the influence of innovativeness on firms' performance, highlighting that performance is affected by the coherence of the configuration of innovativeness, relational trust and combination capability.

Abstract

Purpose

This paper aims to further understand how firms transform external information into marketing innovation. The specific aim is to analyse the mediating role of product innovation and organizational innovation in the relationship between external information and marketing innovation.

Design/methodology/approach

The study builds on the 2012 database Technological Innovation Panel (PITEC) with a sample of 994 manufacturing firms. The data are analysed using partial least squares structural equation modelling (PLS-SEM).

Findings

The results show how external information obtained about relationships with suppliers, customers and competitors leads to marketing innovation. The study demonstrates the mediating effects of product innovation and organizational innovation on the relationship between external information and marketing innovation.

Practical implications

Firms should utilize external information flows to innovate in both their products and organization as a prerequisite to marketing innovation.

Originality/value

This paper provides linkages between perspectives of networks, innovation and marketing to better understand the background of the least studied dimension of innovation – marketing innovation. The main contribution is to explain how firms use external information to achieve marketing innovation through product and organizational innovation.

Abstract

Purpose

When selecting manufactured foods, customers consider several product features. Given the contemporary trends of food consumption, the purpose of this paper is to determine the influence that some demographic and psychographic key variables have on the chances of a consumer belonging to a market segment characterised by health-related food preferences.

Design/methodology/approach

The food choice scale is revised to develop a multidimensional measure of the factors underlying consumer food choices. Data of 288 sampled consumers were used to validate the scale and to group consumers into four segments based on the value assigned to several food-product meta-attributes. Depending on these food choice values, the study identified four dissimilar clusters: utilitarian, protecting, toning and highly demanding.

Findings

Consumers use multiple attributes when choosing food products. However, emerging segments tend to prefer health-related attributes over utilitarian or conventional attributes, such as price, flavour or accessibility. The consumers of these segments tend to be older, more health conscious and more prone to psychological health risks.

Originality/value

Demographic and psychographic traits tend to drive trade-offs between health- and non-health-related attributes when considering food products. Several multivariate methodologies were innovatively coupled to characterize consumers based on their healthy food preferences and individual traits.
