Abstract

Recent years have seen a significant increase in the use of inkjet technology for printing on textile fabrics. Typical inkjet printed textile products included curtains, large advertising posters, flags and banners. As a result of the need for such inkjet printed products to have a greater durability, especially for outdoor applications, inks containing pigments as the colourants are gaining more interests. However, pigments may give rise to logistical problems in terms of their dispersion stability within the ink formulation, consequently blocking the nozzles within the inkjet print head. This paper reports methods for the preparation of pigment dispersions and of inkjet printing ink formulations and the methods for the evaluation of the suitability of pigmented ink formulations for jet printing on textile materials. In particular, the suitability of three magenta pigments for inkjet inks were assessed and reported.

The purpose of this paper is to present a new constrained optimization algorithm based on a particle swarm optimization (PSO) algorithm approach.

Abstract

Purpose

The purpose of this paper is to present a new constrained optimization algorithm based on a particle swarm optimization (PSO) algorithm approach.

Design/methodology/approach

This paper introduces a hybrid approach based on a modified ring neighborhood with two new perturbation operators designed to keep diversity. A constraint handling technique based on feasibility and sum of constraints violation is adopted. Also, a special technique to handle equality constraints is proposed.

Findings

The paper shows that it is possible to improve PSO and keeping the advantages of its social interaction through a simple idea: perturbing the PSO memory.

Research limitations/implications

The proposed algorithm shows a competitive performance against the state‐of‐the‐art constrained optimization algorithms.

Practical implications

The proposed algorithm can be used to solve single objective problems with linear or non‐linear functions, and subject to both equality and inequality constraints which can be linear and non‐linear. In this paper, it is applied to various engineering design problems, and for the solution of state‐of‐the‐art benchmark problems.

Originality/value

A new neighborhood structure for PSO algorithm is presented. Two perturbation operators to improve PSO algorithm are proposed. A special technique to handle equality constraints is proposed.

Abstract

Purpose

Singapore is transforming from a “garden city” to a “city‐in‐a‐garden”. Designing for safety is recognized by researchers and some governments as a best practice in facilitating eventual worker safety within the built environment. The purpose of undertaking this research was to understand and describe the status of safe design for skyrise greenery in Singapore.

Design/methodology/approach

A total of 41 rooftop and vertical greenery systems were observed with a focus on access, fall from height, and planting considerations.

Findings

Rooftop greenery systems in Singapore were found to be adhering to safe design principles. Vertical and ledge greenery systems, on the other hand, are newer arrangements and were found to be in need of design for safety guidance.

Originality/value

The results add to the body of knowledge in the area of safe design and skyrise greenery and will aid those seeking to understand from a policy and practice perspective.

Abstract

Purpose

This study aims to understand the impact of the Covid-19 pandemic disruptive event on delivery of the built environment degree apprentice programme in higher education in the UK and identify the key strategies to minimise the effect.

Design/methodology/approach

A qualitative approach was used to collect and analyse data from a sample set of built environment degree apprenticeship stakeholders. Semi-structured interviews were conducted with 17 key stakeholders to collate emerging themes on their perceptions of the impacts of the pandemic and strategies to adopted to minimise it.

Findings

The investigation reveals that the core impacts of Covid-19 on the apprentices training programme are lack of access to the site, furlough, limited access to off the job training, limited interaction with tutors and peers, too much time on the screen, limited pastoral care and lack of contact with a mentor. The census from the research participants is that despite the development and gain with the various virtual platform used during pandemic physical meetings with their mentor remain pivotal to the built environment apprentices learning and training.

Practical implications

The results provide relevant stakeholders and actors supporting degree apprentices training programmes (training providers and employers, among others) with the information needed to improve the delivery of built environment degree apprenticeship training programmes during a disruptive event Covid-19. The study identifies various strategies to minimise the impact of disruptive events on the apprentices training, including technology, regular meeting with mentors online, and personal and pastoral care.

Originality/value

The study is the first to document the impact of the Covid-19 pandemic on degree apprenticeship programs in the built environment. This study provides an in-depth understanding of how these programs have been affected and offers potential solutions to reduce or mitigate potential damage. The research will inform future policy decisions related to degree apprenticeship programs in the built environment.

Abstract

Purpose

Although interdisciplinary research is an increasing trend in scientific funding projects, they are suffering from a lower probability of being funded. The purpose of this paper is to analyze the current situation on successful case of funding application and provides suggestions on how libraries can expand services to help scientific funding application.

Design/methodology/approach

This paper utilizes the co-occurrences of disciplinary application codes to construct an interdisciplinary knowledge flow network. Based on 193517 sponsored projects of the National Natural Science Foundation of China, the authors study the interdisciplinary flow of knowledge and investigate the evolution of network structure using social network analysis.

Findings

Results show that the interdisciplinary knowledge flow network is not only a small-world network but also a scale-free network. Two main knowledge flow paths across scientific departments exist, showing the heterogeneity of knowledge distributions across scientific disciplines. The authors also find that if two disciplines in the same scientific department both have a wide influence to other disciplines, they are more prone to link together and create a knowledge chain.

Originality/value

Funding consultation currently has not occupied an advisory role either in library services or in the research team. This paper conducts a co-occurrences network analysis of interdisciplinary knowledge flow in scientific funding projects. Considering the complexity of funding application and the advantage of traditional library services on information collection, integration, and utilization, the authors conclude the possibility and necessity of embedding funding consultation in traditional library services.

Abstract

Purpose

This paper aims to develop an empirical understanding of the local identity changes of Chiang Mai heritage city from residents’ perspectives from when the city was pushed forward to inscription on the list of UNESCO World Heritage Sites during a period of transformation in tourism development. The indicative themes of identity change are proposed in a conceptualised model of the multiple stages of identity change in transformational tourism development.

Design/methodology/approach

This study applied the qualitative approach to gain insight on local residents in Chiang Mai. Twenty-two semi-structured interviews were conducted with local residents who underwent transformational experiences with the city, including life-changing tourism experiences with mixtures of senior citizens who were born in the city, migrants and local experts. Site observations and secondary data supplemented the interviews were used in triangulation with identity changes during the transformational tourism period.

Findings

This study’s findings revealed identity changes in locals’ way of life regarding tradition and culture and the increased urbanisation. The indicative themes that caused local identity changes included tourism demand, national policy and new critical emerging issues of capitalism and education are underlined. The way of life in local community transition, tradition and culture has been distorted by effective destination marketing, However, the positive perspectives of identity changes were explored in this study.

Originality/value

This study fills a research gap, given that few scholars (Gu and Ryan, 2007; Lean, 2009; Lemmi et al., 2018; Reisinger, 2015; Robledo and Batle, 2017; Willson et al., 2013; Xue et al., 2017) have conducted in-depth studies on identity change problems that are caused by rural to urban transformational tourism development.

Abstract

Purpose

Due to an increase in energy demands, it has become vital to devise efficient energy policies. Literature has suggested multiple factors influencing the consumption of specific energy types. Among others, institutional quality (INQ) is another factor that can determine energy consumption. Given this, the current study aimed to investigate the impact of INQ on fossil fuel energy (FFE) and renewable energy consumption (REC).

Design/methodology/approach

The empirical analysis was conducted on 20 years (2000–2019) of data from South Asian economies, and regression among variables was established by employing the dynamic ordinary least square and fully modified ordinary least square models. The selection of both techniques is subject to the existence of cointegration identified by the Johansen cointegration test. Other pre-estimation techniques include cross-section dependence and unit root testing validating the estimation of coefficients in the long run.

Findings

The analysis mainly reveals the negative impact of INQ on FFE and the positive impact of INQ on REC. The authors further find the asymmetric impact of control variables including foreign direct investment inflow, economic growth, inflation rate, financial sector development and energy investment on the consumption of both types of energy.

Research limitations/implications

Given the positive influence of INQ on REC, it is recommended to focus on improving the efficiency of institutions specifically those that are directly linked with energy-related policies. A better INQ can ensure environmental sustainability by enhancing the consumption of renewable energy. Therefore, it is advised to exert more efforts to improve the INQ.

Practical implications

In view of the positive influence of INQ on REC, it is recommended to focus on improving the efficiency of institutions specifically that are directly linked with energy-related policies. A better INQ can ensure environmental sustainability by enhancing the consumption of renewable energy. Therefore, it is advised to exert more efforts for improving the INQ.

Originality/value

This study offers robustness to the empirical findings of existing literature on the INQ-REC nexus and complements the underdeveloped literature on the INQ-FFE relationship.

Abstract

Purpose

This study investigates the impact of financial development, measured by the ratio of broad money to gross domestic products, on de jure central bank (CB) independence (CBI) in 17 countries in the Asia–Pacific region from 1995 to 2014.

Design/methodology/approach

This study uses the feasible generalized least squares (FGLS) approach, which is suitable since the CBI equation suffers from contemporaneous correlation, serial correlation and heteroscedasticity.

Findings

The FGLS results suggest a positive association between CBI and financial market development (FMD). This relationship is confirmed when estimating different indicators of de jure CBI and adopting the panel-corrected standard error estimate. However, the statistical significance of FMD is not supported when the ratio of domestic credit to the private sector to GDP is measured.

Research limitations/implications

It is significant to have a developed financial system to foster a better CBI. Moreover, it is important to measure the influence of financial market players on the operations of a CB.

Originality/value

The financial market in the Asia–Pacific has improved over the years. Hence, the results show the determinants of CBI in the Asia–Pacific, especially the role of FMD.

Abstract

Nigeria has been ravaged by terrorist activities which has made the country unsafe for Nigerians and foreign investors. The motivation of this study arises from the dearth of research applying quantitative empirics to the determinants of terrorism in a specific country. To achieve this goal, vector autoregressive (VAR) model was applied using data from Global Terrorism Database (GTD), International Country Risk Guide (ICRG) data, Stockholm International Peace Research Institute (SIPRI) data, and Transparency International. Stata 13 software was used for estimation. The results show that ethnic violence, absence of good governance, presence of corruption, and rises in military expenditure are part of the causes of terrorism in Nigeria. It is, therefore, recommended that internal security should be maintained to minimize the occurrence of ethnic violence and ethnoreligious biases (sentiments) in the discussion of issues concerning Nigeria. Also, politicians should stop the proliferation of arms, as this will cease the violent reactions before and after elections. Finding lasting solutions to corruption using constitutional means will improve the quality of governance, which will improve the welfare state of the people and reduce restiveness.

Abstract

In 2019, Brazil had approximately 53.4 million entrepreneurs, of which 60.2% were start-ups. The contingent of nascent entrepreneurs was 11.1 million people and in just one year it grew 390%, a fact that can be explained, on the one hand, by the beginning of the economic recovery of the country which, although timid, began arousing with the gross domestic product closing the year 2019 with growth of 1.1%, and on the other hand, by the slow cooling of the national unemployment rate that reached 11.0% in the last quarter of 2019 (IBGE, 2019). Women have been occupying an important space in the country's entrepreneurial activities, with an initial specific rate of entrepreneurship (total early-stage entrepreneurial activity (TEA)) of 23.1%, similar to that of men, and established specific rates of entrepreneurship (total establishing entrepreneurial activity (TEE)) of 13.9% (GEM, 2019). Despite the enthusiasm brought by the numbers, it is necessary to pay attention to what are the entrepreneurial activities performed by these women, since in a country like Brazil, transformations brought by innovative thoughts, technological development, and expansion of education are not privileges of the entire population. Besides the differences between genders, even among women, the impact of changes in society occurs in different ways, and the “pure” concept of entrepreneurship, associated with innovation and the creation of new products and services, is valid for only a portion of them, leaving to others the broader concept related to creativity, risk, use of available resources, and economic sustainability in a context where individual characteristics and unfavorable structural conditions are intertwined (Haas, 2013). In this sense, the objective of this work is to present the national reality of female entrepreneurship, contributing with the understanding of who are the Brazilian women entrepreneurs that correspond to these “pure” and broad concepts and, therefore, shed light on new studies and research that can contribute with more accurate diagnoses about these women.
