Abstract

Purpose

The purpose of this paper is to present a new scheme of public–private partnership (PPP) within the framework of motorways of the sea (MoS) similar to that of an equity joint venture along with a methodology for valuing risk transfers arising from options embedded in the clauses included in such agreement.

Design/methodology/approach

The architecture of the proposed PPP is an adaptation to the scope of a MoS of collaborative schemes commonly used in industry such as equity joint ventures. The methodology for valuing options involved making use of a valuation tree of optimal cashflows along with algorithm designs from the field of financial and real options.

Findings

The proposed structure of public–private equity joint venture (PPEJV) increases the stability of private–public collaboration as compared with standard PPPs, so as to achieve the desired modal shift. The analyzed case study shows how the methodology provides valuable numerical information for both negotiating partners and policy makers.

Practical implications

This study provides a quantitative tool for policy makers to redefine the role that public agents and public funds should play in a future sustainable mobility model.

Originality/value

The originality of the authors’ contribution to the field of PPPs in transport is triple. First, there is no precedent in the literature on PPPs of an architecture similar to that of the proposed PPEJV. Second, unlike the usual practice in the valuation of financial or real options, no prior structure is assumed for modelling the behaviour of cashflows. Third, the type of options addressed is not usual neither in the real options literature in general nor in the valuation of guarantee mechanisms included in PPPs in particular.

Abstract

Purpose

Over the last decades, the development of entrepreneurial activity has allowed greater growth and economic development in Spain. However, within the analysis of Spanish entrepreneurial dynamics, insufficient attention has been paid to a key group: senior entrepreneurs. The fact that the first two decades of the 21st century have been accompanied by the two worst economic crises in remembrance since the Great Depression of the 1930s has had a great impact on the professional careers of the group of senior workers, whose careers have been cut short due to the closure of companies. In this way, the present work delves into the reality of senior entrepreneurs in Spain, analyzing the main characteristics of this group, which is becoming increasingly important in society.

Design/methodology/approach

Using microdata from the Spanish National Statistics Institute's Labour Force Survey, the study focuses on reference persons who, being 50 years of age or over and actively working, work as an entrepreneur and have started their activity in the last 12 months. The study covers, in turn, the analysis period of the fourth quarters from 2005 to 2020. In relation to the methodology, the work focuses on the use of binary logistic regression techniques, given that the phenomenon to be studied is binary in nature: entrepreneurship or not.

Findings

The main conclusions drawn are the importance of sociodemographic factors such as educational level, age, the profession of the couple as well as the fact of having or not having children. The sector of activity and region are also significant. It is also concluded that senior entrepreneurship in Spain is of a necessary nature, considering the evolution of unemployment and decisions based on pension reform.

Research limitations/implications

The main limitations of the study refer to the lack of socioeconomic information. Thus, it would be interesting to know the link among the sociodemographic characteristics and the economic situation of the professionals, as well as the fact of whether they have started from a previous situation of unemployment or employment.

Practical implications

The obtained conclusions allow progress to be made in the generation of economic policies aimed at the professional reorientation of a group of workers who, due to labor market circumstances, are obliged to end long professional careers and to seek alternatives. In fact, entrepreneurship is a viable professional alternative for these professionals.

Originality/value

Despite the importance of senior professionals in the Spanish economy, more research is needed on their characteristics and needs. Despite important studies such as Socci et al. (2020) or Perez-Encinas et al. (2021), there are not many studies for the Spanish reality. This paper seeks to deepen the understanding of the sociodemographic characteristics of Spanish senior entrepreneurs, based on current public information and considering different stages of the economic cycle.

Abstract

Purpose

In this work, the authors aim to present a compact low-cost and portable spectral imaging system for general purposes. The developed system provides information that can be used for a fast in situ identification and classification of samples based on the analysis of captured images. The connectivity of the instrument allows a deeper analysis of the images in an external computer.

Design/methodology/approach

The wavelength selection of the system is carried out by light multiplexing through a light-emitting diode panel where eight wavelengths covering the spectrum from ultraviolet (UV) to near-infrared region (NIR) have been included. The image sensor used is a red green blue – infrared (RGB-IR) micro-camera controlled by a Raspberry Pi board where a basic image processing algorithm has been programmed. It allows the visualization in an integrated display of the reflectance and the histogram of the images at each wavelength, including UV and NIRs.

Findings

The prototype has been tested by analyzing several samples in a variety of applications such as detection of damaged, over-ripe and sprayed fruit, classification of different type of plastic materials and determination of properties of water.

Originality/value

The designed system presents some advantages as being non-expensive and portable in comparison to other multispectral imaging systems. The low-cost and size of the camera module connected to the Raspberry Pi provides a compact instrument for general purposes.

Abstract

Purpose

Although several previous studies were focused on examining the determinants of research productivity, the knowledge of the competences and motives that lead researchers to achieve relevant scientific performance remains unclear. This paper is aimed at contributing to this gap in the research by proposing a typology to understand academic researchers' traits and extending the traditional “more is better” approach, which assumes that higher levels of competence and motivation are always preferable.

Design/methodology/approach

Cluster analysis was applied to a sample of 471 Spanish academics to examine diverse combinations of human capital attributes – knowledge, skills, and abilities – and two sources of motivation – intrinsic and extrinsic.

Findings

Four researcher profiles were identified: (1) high vocational academics; (2) motivated academics; (3) self-starter academics and (4) reactive academics. Based on these preliminary findings, we present conclusions about the functioning and productivity of academic researchers.

Originality/value

This paper contributes a novel typology of researchers to the extant literature based on the variables of academic human capital and motivation. The findings indicate that a required and specific combination of attributes better fits the reality of research activities.

Abstract

Purpose

The knowledge generated by academics in the field of management is often criticized because of its reduced relevance for professionals. In the review of the literature, the authors distinguish between three streams of thought. The review of the literature and the understanding of the research streams that have been addressed by the academic–practitioner gap in management has allowed to clarify that what truly underlies each of these approaches is a different assumption or paradigm from which the management science focusses.

Design/methodology/approach

This paper reviews the main approaches that have analysed this topic, drawing a number of conclusions.

Findings

The knowledge generated by academics in the field of management is often criticized because of its reduced relevance for professionals. In the review of the literature, the authors distinguish between three main perspectives. The review of the literature and the understanding of the research streams that have been addressed by the academic–practitioner gap in management has allowed us to clarify that what truly underlies each of these approaches is a different assumption or paradigm from which the management science focusses. To represent the findings of the literature review in this sense, the authors will present, first, a model that serves as a framework to interpret the different solutions proposed in the literature to close the gap from a positivist paradigm. Subsequently, they question this view through a reflection that brings us closer to a more pragmatic and interpretive paradigm of management science to bridge the research–practice gap.

Originality/value

In recent studies, researchers agree that there is an important gap between management research and practice, which may bear little resemblance to each other. However, the literature on this topic does not seem to be guided by a rigorously structured discourse and, for the most part, is not based on empirical studies. Moreover, a sizeable body of literature has been developed with the objective of analysing and contributing solutions that reconcile management researchers and professionals. To offer a more systematic view of the literature on this topic, the paper classifies previous approaches into three different perspectives based on the ideas on which they are supported. Finally, the paper concludes with some reflections that could help to reorient the paradigm from which the management research is carried out.

Abstract

Latin American countries must prioritize energy efficiency and renewable energies in their energy policies. This has been debated for the past few decades. However, it is impossible to deny that energy efficiency and renewable energies have significant potential to mitigate the adverse effects of ever-increasing energy consumption induced by economic growth and the transformation of societies toward more energy-intensive models. This chapter identifies how sustainable energy policies could be considered successful in various Latin American economies through an active review and comparison of traditional energy models and their transition and respective consequences. The chapter concludes that there are national energy plans in countries in the region with a sustainable approach, and that clean energy and renewable sources have great potential. But it is also concluded that there is still a long way to go concerning legislation and legal frameworks.

Design/methodology/approach

A survey was conducted with 250 students from a university in southern Brazil. The data were analyzed by structural equation modeling.

Findings

The main results proved that the built environment, price fairness and teaching care have a significant and positive influence on the satisfaction of university students.

Practical implications

The factors presented explanation power for student satisfaction, which shows that they are essential aspects and, therefore, must be observed by universities to satisfy their students.

Originality/value

The study identifies the impact of factors such as the environment, price and teaching service on student satisfaction.

Abstract

Purpose

This paper aims to describe how an academic library is using federal grant money to contribute to Latino student success by strengthening library collections, archives, and information competence.

Design/methodology/approach

This paper examines the inequalities faced by US Latinos in higher education and how the Oviatt Library at California State University Northridge is addressing this through a project funded by a Hispanic‐Serving Institutions (HSI) Program grant from the US Department of Education. The grant project has three objectives: 1) Increase students' library use by expanding the library's collection of Latino‐related materials, library instruction program, and outreach; 2) Acquire and provide access to primary archival materials related to Latino individuals and organizations in the local community; and 3) Create and administer valid and reliable information competence assessment tools.

Findings

Grant money can be an important tool for contributing to a library's ability to respond to the needs of its community.

Originality/value

This case study should encourage libraries to seek funding from sources that are not generally considered.

Abstract

Purpose

This paper aims to study the dynamics of bitcoin prices in Brazil, a large emerging economy with an unregulated bitcoin market.

Design/methodology/approach

First, this study tests if the Law of One Price (LOOP) is valid for bitcoin prices in Brazil, conducting tests with data from three Brazilian exchanges. Next, this study documents bitcoin price dynamics in the short run by studying the price discovery mechanism in these exchanges. This study uses Information Share and Component Share, combining the two measures to obtain an Information Leadership Share (ILS) measure.

Findings

This study finds a common trend within bitcoin prices among a set of exchanges, with cointegration tests between the price series indicating that LOOP is valid in Brazilian markets in the long run. ILS indicated that, for closing prices, the most liquid exchange (Foxbit) leads discovery, whereas the least liquid (Local Bitcoin) lags, with Mercado Bitcoin in the middle both in terms of discovery and liquidity. Finally, this study provides evidence that the price variation in the market that leads price discovery can be used to construct an arbitrage in another exchange.

Originality/value

This research brings the first evidence of a price discovery mechanism for exchanges in Brazilian Reais. Although LOOP is valid in the long run, price leadership in bitcoin markets potentially create arbitrage opportunities in the short run. This study contributes to the growing literature of bitcoin prices with novel evidence from a large emerging economy.
