Abstract

Purpose

This research aims to gain a holistic understanding of how video conferencing (VC) apps' media characteristics influence individuals' perceptions of VC apps and, ultimately, their use and continued use in professional settings.

Design/methodology/approach

A conceptual research model is developed by integrating constructs from media synchronicity theory (MST), social presence theory and the unified theory of acceptance and use of technology (UTAUT2) model, as well as ubiquity, technicality and perceived fees. Structural equation modeling (SEM) is used to empirically test the conceptual model using data collected from 252 working professionals from the European Union.

Findings

The results reveal that while performance expectancy (PE) and facilitating conditions (FC) are fundamental to VC app use, these factors alone do not explain the use and continuing use of VC apps in the professional context. Media characteristics that include synchronicity, social presence, and ubiquity are equally crucial to professionals using VC apps. It also confirms the moderating effect of convergence on the relationship between synchronicity and PE and the moderating effect of technicality and perceived fees on the relationship between ubiquity and FC.

Originality/value

For researchers, the study offers insights into the extent to which technological and socially derived characteristics of VC apps influence the routine tasks undertaken by professionals in virtual work settings. For practitioners, recommendations pivotal to the use of VC apps are presented to promote higher acceptance and improved well-being of the professional workforce.

Abstract

Purpose

This study aims to design and empirically test a model where autonomy affects partnership (PT) and entrepreneurial orientation (EO), which in turn improves competitive aggressiveness (CA), market orientation (MO) and PT; to verify the impact of CA on MO and PT; and to determine to what extent MO mediates the EO–PT relationship.

Design/methodology/approach

The authors used a quantitative approach to test 101 Brazilian firms from different sectors, analyzed by structural equation modeling using the partial least squares–structural equation modeling.

Findings

Results show that autonomy improves EO and PT. EO positively affects CA, MO and PT. CA impacts MO positively, and MO mediates the EO–PT relationship, although it reduces the possibility of PT.

Research limitations/implications

Although 101 firms could be a “small sample,” the authors validated it according to Hair et al. (2009) and Chin et al. (2003). Their first contribution is to extend the works relating to EO and PT by showing the positive effects of autonomy on EO and PT. Second, to show the mediating effect of MO on the EO–PT relationship. Finally, they draw attention to how firms with EO improve CA, MO and PT; and CA boost MO. Thus, to generalize EO research internationally, like in the emergent markets.

Originality/value

Although EO has attracted significant attention to entrepreneurship research, it is not clear how autonomy impacts a firm's EO and PT, considering the mediating effect of MO on the EO–PT relationship; if EO influences CA and MO, and the impact of CA on MO and PT.

Abstract

Purpose

Shrinking population can have significant negative impacts on the social and economic fabric of a city. This paper aims to understand different urban transportation policies to respond to population decline in shrinking cities by examining two case studies of urban interventions in mid-size cities in Japan.

Design/methodology/approach

The paper analyzes the implementation of sustainable mobility strategies in the urban transport sector in the Japanese cities of Toyama and Kanazawa, which risk having their populations significantly reduced in the next decades. The analysis is based on case study research that uses the data and information collected through desk and field research. Interviews with local actors, as well as published policy and academic documents on the case studies provided critical data and information to analyze the case studies.

Findings

Both cities have tried to make urban mobility more sustainable via different strategies. Toyama used more structural changes, called the “sticks and dumplings” approach, having land use incentives and the Light Rail Transit reinforced by bus routes as the backbone of its strategy. Kanazawa relied on a city center revitalization plan to densify residential use in the city center.

Practical implications

More structural interventions are necessary to change the declining of shrinking cities, mitigating some of the negative effects. City administrations need to have clear policy priorities and should not allocate their limited resources to competing policy agendas.

Originality/value

The study is unique as it is one of the first efforts to analyze urban transportation interventions in shrinking cities in Japan.

Abstract

Purpose

This paper aims to contribute to the explanatory debate of the entrepreneurial intention-action gap that results from the interposition of normative-regulatory, sociocultural and economic-financial barriers facing potential and intending entrepreneurs.

Design/methodology/approach

Grounded on post-positivist position, the authors propose a quantitative approach, surveying 569 potential and intending entrepreneurs from a longitudinal and stratified sample of 22 years.

Findings

The economic-financial barrier is the most important, followed by the sociocultural except in the period in which access to banking financial support is facilitated, where the order is reversed. The impact of the normative-regulatory barrier is statistically relevant, but irrelevant on the magnitude. The results also allow us to conclude that a lower development of the project accentuates the entrepreneurial intention-action gap and, finally, support the existence of a medium/long-term temporal relation between entrepreneurial intention and entrepreneurial action.

Research limitations/implications

From an empirical standpoint, the sample was limited to potential and pretending entrepreneurs from one national institution and one country. This limits the scope of generalization. Further studies in multiple contexts should be undertaken.

Practical implications

The study points to contradictory results with the Global Entrepreneurship Monitor – Portuguese Reports, which, if confirmed, require the reformulation of Portuguese national policies in the promotion and development of entrepreneurial activities.

Originality/value

The study is novel by providing new insights about entrepreneurship and the entrepreneurial intention-action gap.

Abstract

Purpose

The purpose of this paper is to construct and evaluate value and growth portfolios in Portugal, Italy, Ireland, Greece and Spain, which are commonly known as the EU PIIGS, from 2003 to 2015. Previous research evidence suggests that stocks trading at a lower price relative to their fundamentals (value stocks) tend to outperform stocks that trade at higher prices (growth stocks) in the long run. Although this market anomaly has been studied immensely worldwide, especially for the US stock market, there is no clear evidence whether such an assertion is applicable in less-renowned countries.

Design/methodology/approach

The paper utilises Fama and Macbeth (1973) regressions and its model extensions.

Findings

This paper finds a significant value premium in these countries, which is compatible with previous studies conducted worldwide.

Originality/value

To the best of the authors’ knowledge, this is the first attempt to examine this asset pricing anomaly in the PIIGS.

Abstract

Purpose

The objective of the present study is to assess the financial literacy levels of students at a Brazilian university and investigate how these levels are affected by profile characteristics and personality traits.

Design/methodology/approach

Data were collected using SurveyMonkey, and a link to the questionnaire was sent by e-mail. The questionnaire contains three blocks of questions: demographics, financial literacy and personality traits. Ordered logistic regression was applied to a sample of 1,312 students.

Findings

Younger participants, those with higher incomes and men were more likely to have a high level of financial literacy. The same was true of those who were less extrovert, i.e. assertive, sociable, optimistic and communicative students. These results contribute to the field by indicating which population segments should be prioritized in efforts to promote financial literacy.

Originality/value

To the best of our knowledge, no study has compared Financial Literacy and Personality Traits in Brazil, a developing country that is only beginning to develop national financial literacy strategies.

Abstract

Purpose

This paper aims to use quantitative metrics to chart the unique history leading to Brazil’s leadership in renewable energy and identifies a set of meta-scenarios that define possible future carbon performance. These meta-scenarios provide a context for discussing specific energy policy implications both at the national scale and from the perspective of Brazil’s urban centres.

Design/methodology/approach

The paper defines and uses three metrics – energy efficiency, decarbonisation and carbon efficiency – to plot both Brazil’s historic energy pathway and a set of future energy scenarios put forth by various national and international energy agencies. The authors then use a meta-scenario approach to group these alternate pathways, identifying specific policy levers associated with the realisation of each.

Findings

The authors identify plausible policy changes that will help move Brazil off a current trajectory of stagnated energy performance to a “greener” scenario in which carbon efficiency improves even as Brazil’s economic growth continues. Such policies include energy efficiency programmes and continued expansion of the country’s already extensive hydropower and biomass capacity. Adoption of policies that would put Brazil on a more aggressive path towards a global sustainability scenario currently seems impractical.

Originality/value

This paper brings a standardized set of metrics to bear on Brazil’s unique energy history, which in turn helps identify specific policy impacts for continued GHG reduction in Brazil’s future from national and urban perspectives.

Abstract

Portuguese handicrafts are distinctive artisan products that have been shaped by cultural and historical conditions. The aim of this chapter is to focus on understanding the inherent innovativeness embedded within different handicraft that is made in Portugal. This involves taking a country perspective to handicraft production and the reason why it has continued or revived over time. This involves focusing on the role of entrepreneurs in the handicraft industry and how artisan entrepreneurship can be utilized. Specific examples of Portuguese handicrafts are stated in this chapter that showcase the cultural connections individuals feel. Theoretical and managerial implications are stated that highlight the importance of handicrafts to cultural preservation. Future research suggestions are also stated that stress the need to continue research into Portuguese handicrafts and artisan entrepreneurship.

This chapter examines the economics of alternative healing in Brazil.

Abstract

Purpose

This chapter examines the economics of alternative healing in Brazil.

Methodology/approach

Two narratives are selected from extensive observations and interviews over a period of years. The presentation chronicles the accounts of people experiencing physical symptoms who sought further advice from friends and relatives after visits to conventional medical providers failed to cure them.

Findings

In response to a recommendation from one of those consulted, one person went to a spirit “received” by a Kardecist/Spiritist healer-medium while the other obtained treatment from an otherworldly being at an Umbanda center. The respective “therapeutic” procedures are described and analyzed in terms of the beliefs and the worldviews of each of the traditions. If satisfied with the outcome, the patient fulfills an implicit bargain with the otherworldly being(s) and its religious group by adopting their beliefs and practices. This conversion is “payment” for the healing services rendered.

Social implications

Since some treatments are successful and others are not, the implications of this exchange is that many Brazilians may change their religions several times during their lifespan. As a result of this behavior individuals circulate among the several religious groups that are always in competition with each other.

Originality/value

The analysis provides a distinctive insight into, and original way to understand, alternative health care in Brazil.
