This article provides an overview of the panel vector autoregressive models (VAR) used in macroeconomics and finance to study the dynamic relationships between heterogeneous assets, households, firms, sectors, and countries. We discuss what their distinctive features are, what they are used for, and how they can be derived from economic theory. We also describe how they are estimated and how shock identification is performed. We compare panel VAR models to other approaches used in the literature to estimate dynamic models involving heterogeneous units. Finally, we show how structural time variation can be dealt with.

The purpose of this paper is to examine the possible moderating role of organisational characteristics (organisational structure, management style and decision-making style) in the relationship between strategy and organisational performance among large construction organisations in South Africa.

The study adopted a quantitative research approach using a questionnaire survey to obtain data from 72 large construction organisations in South Africa. Using hierarchical multiple regression, the paper examines the relationship between the constructs discussed in the study.

The internal characteristics of the organisation form the vital basis for achieving optimal performance. The results obtained from the analysis revealed that decision-making style directly influences the measure of organisational effectiveness, while it could also be inferred that organisational characteristics partly moderate the relationship between competitive strategy and organisational performance. The findings indicate that internal characteristics is one of the means through which organisational strategic factors and contextual aspects are organised to achieve greater organisational performance levels.

The findings have theoretical implications for strategic management literature in construction as it extends the scope of research on strategic management from assessing a set of individual management practices to evaluating a complex mechanism that connects internal characteristics and competitive advantage. It is believed that this study will contribute positively to the role of organisational characteristics in the competitive strategy-performance relationships in large construction organisations in South Africa and to the ongoing discussion on emerging strategic management issues in construction.

This paper aims to review the current joint master’s program between two international institutions in the USA and Costa Rica; to identify students’ perceptions and experiences with the sustainability house (SH); and to apply these experiences in an effort to improve the practical learning environment for future students.

In an effort to understand student outcomes provided by the SH, an in-depth literature review on practical learning environments and interview methods were applied. The following open-ended questions were asked in an effort to gather and consolidate student experiences with the SH. What are your experiences in/with SH? Please tell us briefly about your experiences. The language has been adjusted and interviewers answered questions and made clarifications if asked to. Master’s in international sustainable tourism (MIST) program students were selected for this study. Participants’ responses were recorded using the computer-assisted personal interviewing technique.

The most important characteristic students recognized about the SH is that it “provided us a safe place to fail”. One student described SH as “[…] a safe space where students can gain experiences of learning new processes firsthand without external pressures (e.g., on-the-job training, eventuation, and financial analysis)”. The safety attribute of the SH environment is considered as a comfortable place to learn from other classmates or visitors (mostly volunteers and interns). It is a “real” hospitality and tourism business-learning center, which is a great benefit to the students not only because of its environment but also because of the diversity among student’s educational and professional backgrounds.

The primary limitations of this study need to be addressed. The number of interviews was very limited with one year data which could affect the generalizability of this study. In addition, it was not clearly explained to the student what rubrics and standardized metrics were used during interview process; after interview, students were asked to provide a better way to improve the research outcomes. For further studies, it is strongly recommended to provide the direction to make sure it applies to the conditions that are prevalent in the existing site to be examined.

Both strategies that link the SH to this MIST program have significant merit. Students implementing best practices in the courses have clearly identified the challenges of implementation, but all agree that there is tremendous value in the experiences they have received during their studies. Furthermore, using the SH as an engagement tool has motivated students to consciously interactive and collaborative in a more proactive manner.

This unique experience and operational competency at the SH provides participants with an in-depth understanding of the context and challenges of sustainability but needs to be detailed and promoted more in the future. The SH is facilitating a learning environment among not only students but also faculty and staff. The results clearly indicated that the SH has influenced sustainable behaviors by promoting interactive engagement.

This study explores the role of smart voice assistants (SVAs) as purchase recommenders, a phenomenon the authors term “word of voice” (WOV) communication. By integrating human–computer interaction (HCI) literature and electronic word of mouth (eWOM) research, the authors examine what makes consumers trust in SVA-transmitted WOV communication following their initial interactions with their SVAs during a purchase process (i.e. post-trust); and the authors propose that consumers' perceptions of their SVAs' smart capabilities (i.e. cognitive, emotional and social) are critically important for building this trust. Moreover, the study explores the influence of post-trust on consumers' adherence to WOV communication, measured by three types of behavioural intentions.

Data from a survey of 202 United States (US)-based SVA users who employ them to obtain purchase recommendations were collected and analysed. They confirmed the validity of the measurement scales and provided input for the partial least squares modelling (PLS-SEM).

The results demonstrated that post-trust in WOV communication partially or totally mediates the effect of smart capabilities on consumer adherence to WOV communication; identified the key role of cognitive, emotional and social smart capabilities for building consumers' post-trust in WOV and demonstrated the influence of this trust on behavioural intentions.

The present study contributes by examining the employment of SVAs as recommenders during the purchase process; the authors term this type of communication WOV. It analyses consumers with experience of using SVAs in their purchase processes, revealing that post-trust in WOV communication is the psychological mechanism that explains how the smart capabilities of SVAs determine consumer adherence to the recommendations they receive.

The purpose of this paper is to analyse the individual’s experience during the use of Pinterest in a marketing learning process. This experience is a fundamental starting point from which to develop marketing learning processes that flow naturally. Thus, it is necessary to examine the components that determine the individual’s experience and to explore consequences such as collaborative learning and marketing learning performance.

To conceptualise the individual’s experience, this study focuses on her/his state of cognitive absorption (CA) and establishes a second-order formative structure made up of five components: heightened enjoyment, curiosity, control, temporal dissociation and focused immersion. The model is estimated with partial least squares modelling, using SmartPLS 2.0 software.

The results confirm the significant weights of the components, with the exception of focused immersion, and support the influence of overall CA on the proposed outcomes. They also confirm that collaborative learning exerts a positive influence on the individual’s performance.

This study makes three contributions. First, it holistically examines the individual’s experience during marketing learning and the importance of its constituent components. Second, it establishes what the consequences of the marketing learning experience are, taking into account both social and individual factors, that is, collaborative learning and individual performance. Third, Pinterest is proposed as a social network with great potential in marketing learning. It is a well-known network which includes very interesting features for learning contexts. Nevertheless, it has been little studied in research.

El objetivo de la presente investigación es analizar la experiencia del individuo durante el uso de Pinterest en un proceso de aprendizaje de marketing. Este experiencia es un punto de partida fundamental para que el proceso de aprendizaje de marketing se desarrolle de manera fluída. Así, es preciso examinar los componentes que determinan la experiencia del individuo y explorar las consecuencias, como por ejemplo, el aprendizaje colaborativo y los resultados del aprendizaje de marketing.

Con el objeto de conceptualizar la experiencia del individuo, este studio centra su atención en la absorción cognitiva (AC) y propone una estructura formativa de segundo orden compuesta por cinco componentes: mayor disfrute, curiosidad, control, disociación temporal e inmersión enfocada. El modelo es estimado mediante el uso de Modelización de Mínimos Cuadrados Parciales, empleando el software SmartPLS 2.0.

Los resultados confirman el significativo peso de los componentes, con la excepción de la inmensión enfocada, y apoya la influencia de la AC general sobre las consecuencias propuestas. Estos resultados también confirman que el aprendizaje colaborativo tiene una influencia positiva sobre los resultados del individuo.

Este estudio ofrece tres contribuciones. En primer lugar, se examina de manera holística la experiencia del individuo durante el aprendizaje de marketing y la importancia de sus componentes. En segundo lugar, se establece cuales son las consecuencias de la experiencia de aprendizaje de marketing, teniendo en cuenta factores sociales e individuales, es decir, aprendizaje colaborativo y resultados individuales. En tercer lugar, se propone a Pinterest como una red social con un gran potencial en el aprendizaje de marketing. Se trata de una conocida red que incluye interesantes características para los contextos de aprendizaje. A pesar de ello, ha sido escasamente estudiada por los investigadores.

The purpose of this paper is to analyse the effect of positive online consumer reviews (OCRs) on changes in the individual’s evaluations from the pre-purchase to the post-consumption stage, studying satisfaction, attitude towards the firm and purchase intention. The effect of positive OCRs may differ depending on whether the product performance is high or low, i.e., whether the product meets the objectives of the consumer. So, the paper also explores different effects that positive OCRs can have on changes in the individual’s evaluations depending on the kind of performance.

Two studies based on the experimental methodology are carried out and several statistical techniques are applied: confirmatory factorial analysis, mixed between-within subjects analysis of variance and post-hoc analysis.

Results demonstrate that the effect of positive OCRs continues after consumption. Depending on the performance, this effect can be positive (negative) and verify (contrast with) the individual’s pre-purchase evaluations. Moreover, this effect is always more intense when the performance is low.

It explores the changes in the individual’s evaluations about the product and the firm, going beyond the immediate effect of positive OCRs. It also explains the effects of positive OCRs for high and low performance. Finally, it demonstrates that OCR effects are not symmetrical for high and low performance.

Purpose – This chapter provides an overview of issues related to analysing crash data characterised by excess zero responses and/or long tails and how to overcome these problems. Factors affecting excess zeros and/or long tails are discussed, as well as how they can bias the results when traditional distributions or models are used. Recently introduced multi-parameter distributions and models developed specifically for such datasets are described. The chapter is intended to guide readers on how to properly analyse crash datasets with excess zeros and long or heavy tails.

Methodology – Key references from the literature are summarised and discussed, and two examples detailing how multi-parameter distributions and models compare with the negative binomial distribution and model are presented.

Findings – In the event that the characteristics of the crash dataset cannot be changed or modified, recently introduced multi-parameter distributions and models can be used efficiently to analyse datasets characterised by excess zero responses and/or long tails. They offer a simpler way to interpret the relationship between crashes and explanatory variables, while providing better statistical performance in terms of goodness-of-fit and predictive capabilities.

Research implications – Multi-parameter models are expected to become the next series of traditional distributions and models. The research on these models is still ongoing.

Practical implications – With the advancement of computing power and Bayesian simulation methods, multi-parameter models can now be easily coded and applied to analyse crash datasets characterised by excess zero responses and/or long tails.

By integrating the structural contingency and the organizational adaptation theories, this study analyzes the impact of the main variables of organizational structure on convergent change. The authors also examine whether some contingency variables, such as the firm's size, age and sector, may help to explain differences in the relationship between organizational structure and convergent change.

This work was carried out through an explanatory and cross-sectional study. The hypotheses were tested through a multiple regression analysis.

This paper demonstrates that, in Bogota's SMEs, modifications in differentiation and formalization explain convergent change, and that centralization does not affect it. Furthermore, the authors find that the company's size explains these relationships, and that age and sector do not influence them.

The authors provide useful information in this work to guide managers and professionals on the implications of organizational structure and convergent change, more specifically on decisions regarding hierarchical arrangement, job division and processes redefinition.

This work provides empirical evidence with original data for a better understanding of the reality of Colombian SMEs in the Latin American context.

The purpose of this paper is the identification of the magnetic characteristics of the induction load by means of the B–H curve proposed by Fröhlich.

An electromagnetic description of the inductor system is performed to substitute the effects of the induction load, for a mathematical condition, the so-called impedance boundary condition (IBC).

A significant reduction in the computational cost of electromagnetic simulation has been achieved through the use of the IBC, resulting in a computation time approximately 400 times faster than time domain simulation. Moreover, an alternative method has been developed to experimentally identify the parameters that determine the magnetic behavior of the induction load. Finally, further research has been conducted to understand the relationship between the equivalent impedance of an induction load and the excitation current level.

This work is performed to achieve a better understanding of the fundamentals involved in the electromagnetic modeling of an induction heating system.

This paper introduces the dependence on the excitation level based on a first harmonic approximation and extends the IBC to nonlinear magnetic materials which allows the identification of the magnetic characteristics of the induction load.

This article aims to describe the valuable work conducted most recently on competitive strategies. Its purpose is to elaborate on suggestions for theorizing the hybrid form of competitive advantage and stimulate the interest of scholars.

As this article emphasizes hybrid strategies, both electronic and manual methods have detected 15 studies focusing on competitive strategies and their relation to firm performance from 2000 until today.

This article underlines the need to deal more thoroughly with combined-emphasis competitive strategies, which have seriously enhanced Porter’s paradigm, defined in 1980 with three single-emphasis strategic choices. The era in which combining competitive strategies was synonymous with stuck-in-the-middle alternatives has been left behind, and the era in which hybrid strategies suggest the most attractive choices, at least in some circumstances, has already begun.

This article is one of the few stressing conceptual issues of hybrid strategies that emerged from Porter’s (1980) model. No matter how many years pass by, research on competitive strategies will continue, as it considers businesses of any age, size, sector or country. The global challenge of today is how scholars will revise theory to better capture reality. This article intensifies the need for a theoretical framework embracing the full variety of competitive strategies, namely, single-emphasis, mixed-emphasis, no-distinctive-emphasis and stuck-in-the-middle. Nonetheless, due to their complex and multidimensional nature, hybrid strategies receive particular attention.
