Purpose

This paper aims to assess information and communication technologies (ICT) policies for digital transformation in Colombia to determine their effectiveness in technology readiness for Internet of Things (IoT) adoption in small and medium enterprises (SMEs) in the trading sector.

Design/methodology/approach

The authors conducted a longitudinal study using the ICT module of the Annual Trade Survey (2017–2018) to determine the relationship between SMEs in the trading sector adopting ICT applications and ICT policy enforcement. In this sense, this study applied a chi-square test for independence and addressed a descriptive analysis to determine SMEs’ causes for adopting or rejecting ICT applications.

Findings

This study presents the state of ICT adoption in Colombian SMEs in the trading sector between 2017 and 2018, highlighting that technology readiness is crucial for adopting technological trends.

Research limitations/implications

The data source used for the study is only available for analysis one year after implementing ICT policies focused on digital transformation.

Practical implications

The results support the need for the National Government to formulate IoT policies that favor the adoption of e-commerce based on IoT technologies in SMEs in the trading sector.

Social implications

IoT adoption can mitigate e-commerce problems strengthening SMEs’ competitiveness in the trading sector leading the digital transformation in Colombia.

Originality/value

This study presents the need to formulate IoT policies in Colombia focused on deploying IoT applications to strengthen e-Commerce in SMEs in the trading sector.

Abstract

Purpose

The paper aims to focus on airflow and heat transfer inside the human nasal cavity. The contribution of this work is the inertial analysis of the momentum and thermal stress of the cavity throughout the respiratory cycle.

Design/methodology/approach

By means of computer tomography scans, an accurate three‐dimensional anatomical representation of the human nasal cavity was obtained. A three‐dimensional numerical model is presented in order to predict the time evolution of flow patterns during a quiet breathing cycle, covering inhalation and exhalation. An inertial analysis of the momentum and a detailed study of the thermal behaviour during the breathing cycle is carried out.

Findings

Head loss, velocity and temperature values are in agreement with experimental results from previous studies. Based on these results, the influence of the inhalation and the exhalation on the flow pattern and air conditioning has been reviewed. Results suggest that the anterior and posterior turbinate regions are where the air conditioning is primarily produced.

Practical implications

The future goal is to investigate respiratory disorders to increase the effectiveness of the eventual treatment of the pathology. The model could be a useful tool to predict, for instance, the modification of the flow patterns due to septal perforations.

Originality/value

The transient resolution provides insight into the momentum and thermal inertia though the breathing which is far from being well understood.

Abstract

Purpose

One current trend in burner technology is to obtain high efficiency while keeping low levels of NOx emissions. A swirling flow in combustion ensures a fixed position of a compact flame. Therefore, it is necessary to design efficient swirlers. Flow patterns are simulated for the different swirl devices proposed in this work. Two axial-swirlers are studied: one based on curve-vanes consisting of a straight line with an arc of a circle as the trailing edge and the other is the common flat-vanes. The purpose of this paper is to assess the accuracy of different swirl generators using a well-known benchmark test case.

Design/methodology/approach

This work deals with modelling the swirler using two approaches: the general purpose Computational fluid dynamics (CFD) solver Ansys-Fluent® and the suite of libraries OpenFOAM® to solve the Reynolds Averaged Navier Stokes equations, showing there is a slight deviation between both approaches. Their performance involves analyzing not only the Swirl number but also the size of the recirculation zones in the test chamber. A subsequent process on the flow patterns was carried out to establish the intensity of segregation which provides insight into the quality of mixing.

Findings

CFD models are feasible tools to predict flow features. It was found that numerical results tend to reduce the inner recirculation zone (IRZ) radial size. Further, an increase of the swirl number involves larger IRZ and a smaller outer recirculation zone (ORZ). The curved swirler displays a better axi-symmetric behaviour than flat vanes. There is weak influence of the chord vanes on the swirl number. The number of vanes is a compromise of head loses and guidance of the flow.

Originality/value

The paper offers two different approaches to solve turbulent swirling flows. One based in a general contrasted commercial tool and other using open source code. Both models show similar performance. An innovative set up for an axial swirler different from the conventional flat vanes was proposed.

Abstract

Purpose

The purpose of this paper is to represent the conflict of touristification in the central district of Seville to evaluate the dimension of the problem. Therefore, it focuses on the diagnostic representation of the conflict between citizens and tourists, to help define the coexistence of opposing interests and to bring solutions in favour of a liveable urban landscape.

Design/methodology/approach

The research has implied a detailed analysis beyond the observation of data and statistics, which facilitated a complex diagnosis for decision-making. This has led to consider as an initial framework the main tourist resources, official agreements and civil manifestations regarding touristification. Then, factors of tourist density and one in-depth case study of changes in use have been mapped.

Findings

First, an analysis of the urban spaces affected by the tourist dynamics following the degree of habitability of the resident citizens has been led. Second, of the conflict resulting from a relationship between economic activities, the attractiveness of the urban landscape and the tourist use of the space has been mapped.

Originality/value

Through the study of the central district of a city of great heritage value where conflicts begin to occur as a result of tourism, it is intended to contribute to the development of the spatial syntax of the tourist conflict, what could lead to improve responsible urban and social city policies.

Abstract

Purpose

The purpose of this paper is to understand the extent to which new forms of capital are noticed by different members of nonprofit organizations (directors, employees, and volunteers) and valued as a factor of organizational capacity.

Design/methodology/approach

Using survey research methodology, the authors studied a nonprofit institution – a delegation of the Portuguese Red Cross located in Fafe, a city in northern Portugal, by giving a questionnaire to all its members.

Findings

The respondents revealed that the existence of other forms of capital (in addition to financial capital) is recognized and valued and that human capital as a whole is particularly relevant to the fulfillment of the Fafe Delegation of Portuguese Red Cross’ mission.

Originality/value

This is the first study on the perceptions of human capital, social capital and financial capital in a Portuguese nonprofit organization.

Abstract

Purpose

Innovativeness is a critical aspect for the survival and success of the company in the long term. The purpose of this paper is to study how the density of the network in which the company is immersed influences the relationship between environment, dynamism and innovativeness. More specifically, the authors analyse whether the network density acts in a heterogeneous way, worsening or improving the effects of technological and market dynamism on innovativeness, respectively.

Design/methodology/approach

The empirical study was conducted on a sample of 292 companies in the agri-food industry in Spain. In order to test the proposed model, the authors used partial least squares.

Findings

The results show that technological dynamism has a positive effect on the generation and development of a firm’s innovativeness. However, market dynamism does not influence innovativeness. The authors also observe that the interactive effects between network density and dynamism are significant, but in a divergent way. Whereas the interactive effect between density and technological dynamism is negative, the interaction between density and market dynamism is positive.

Originality/value

The main contribution of the study is to show how the level of network density alters the effect of technological and market dynamism on innovativeness. The authors highlight the relevance of network theory to explain the contextual background to innovativeness. The authors also stress the importance of differentiating between the market and technological components of dynamism to further elucidate their effects.

Abstract

Purpose

This paper aims to understand the relationship in developing countries between fiscal consolidation and public investment – a flexible part of the budget that is easier to cut during consolidation effort, but with potentially negative growth effects. Analyzing in detail the case of Peru, the paper explores alternative fiscal rules and frameworks that might help create fiscal space for infrastructure investment.

Design/methodology/approach

The paper analyses trends in public and total infrastructure investment in six large Latin American economies, in the light of fiscal developments since the early 1980s. In particular, the paper explores the association between fiscal consolidations (improvements in the structural fiscal balance) and public infrastructure investment rates. In the second part, the paper analyzes recent changes in the fiscal framework of Peru and shows how they were conductive in creating additional fiscal space.

Findings

The authors argue that post-crisis fiscal frameworks, notably fiscal rules that are increasingly popular in the region, should not only consolidate the recent progress towards debt sustainability, but also create the fiscal space to close these infrastructure gaps. These points are illustrated in a detailed account of recent developments in the fiscal framework and public investment in the Peruvian case.

Originality/value

The paper contributes new evidence to the literature on fiscal consolidation and the composition of government expenditures. While the literature based on evidence from the 1990s has argued that fiscal consolidation plans in Latin America have almost always led to a significant reduction in public infrastructure investment, the paper finds less clear cut evidence when extending the analysis backwards (1980s) and forwards (2000s). The example of the case of Peru is used to explore fiscal institutions and rules that might be useful for other developing countries that face important infrastructure gaps.

Abstract

Purpose

Recently, several regional protected geographical indications (PGI) have been introduced in Italy for extra virgin olive oil (EVOO) with the aim of coping with the substantial failure of protected designations of origin (PDO). This study aims to identify which characteristics consumers expect, in order to anticipate the market success.

Design/methodology/approach

In this study, a survey has been used on a sample of consumers from Sicily, one of the first regions which recently developed a regional PGI for EVOO. Data have been analyzed with a rank-ordered logit model.

Findings

Results yielded that consumers would accept this new product and their expectations correspond to a product with attributes such as: green color, not filtered, not with a sweet taste and with a known brand. A possible target can be represented by young men.

Practical implications

The results obtained anticipate whether this product would be accepted and provides direct indications for producers who wish to enter the market with a PGI EVOO.

Originality/value

This work focuses on consumer behavior toward products that are specifically certified with a recently introduced PGI label, and they still are not so common on the market.
