Abstract

Potato (Solanum tuberosum L. cv. Kara) was grown in Open‐Top Chambers (OTCs) in Northern Egypt at ambient (ca 350 ppm) or doubled CO2 (ca 690 ppm) either in charcoal‐filtered air (15 nl l‐1) or in non‐filtered ambient air (78 nll‐1 O3) to investigate the changes in physiology and yield under long‐term elevated CO2 and/or O3 throughout 100 days. Ambient O3 level reduced net photosynthetic rates, number and weight of tubers by 18 per cent, 41 per cent and 21 per cent, respectively, whereas elevated CO2 caused the opposite effect where it increased the same parameters by 44 per cent, 37 per cent and 20 per cent, respectively. Significant O3 x CO2 interactions were detected. However, O3 caused an increase in GR and POD by 18 per cent and 35 per cent, respectively, while CO2 caused an increase in POD only by 46 per cent, and there was no effect of O3 and/or CO2 on other enzymes. The results of this study are discussed in relation to predicted atmospheric changes.

Abstract

Purpose

The purpose of this paper is to examine the value relevance of intellectual capital (IC) by analysing the relationship between IC efficiency (ICE) and corporate book value of listed firms on main board of Nigeria Stock Exchange.

Design/methodology/approach

This study applies the resource-based theory in formulating two hypotheses that guide the results analysis. By employing a two-step dynamic system generalised method of moments (GMMs), and controlling for the possible endogeneity effect on the parameters estimated, for a sample of 91 listed firms on main board of Nigeria Stock Exchange, this study investigates the association of ICE and corporate book value, namely, cash flow from operation and economic value added (EVA), using data over the 2010 to 2014 financial years.

Findings

The results show a significant positive relationship between overall ICE and corporate book value (cash flow from operation and EVA). This study contributes to recent evidence concerning the value relevance of IC information to investors and other interested stakeholders.

Research limitations/implications

The generalisation of the results to smaller firms, in the alternative securities market, may be inappropriate as study sampled listed firms on the main board of Nigerian Stock Exchange.

Practical implications

Those charged with governance should be concerned with the investment and management of IC as it enhances the economic value and operating cash flow in line with the resource-based theory.

Originality/value

This study is first to consider the ICE study across all sectors in the Nigerian economy using modified Pulic value added intellectual capital. The study controls for heteroscedasticity and endogeneity issues by adoption of two-step dynamic system GMMs.

Abstract

Purpose

This study aims to synthesise and characterise new reactive dyes based on thiazole derivatives which act as chromophoric moieties. These dyes were applied to cotton fabric, resulting in the dyed fabrics exhibiting good colour strength, light fastness and other fastness properties. The antibacterial activity of the dyed cotton fabric was evaluated against gram-negative and gram-positive bacteria.

Design/methodology/approach

The dyes were synthesised in two steps. First, the coupling compound was formed by adding H-acid solution to cyanuric chloride in an ice bath at pH 5 then adding 4-aminobenzenesulphonic acid portion-wise at room temperature and at pH 6-7. Second, different diazonium salts 4-phenylthiazol-2-amine (2a) and 4-(4-methoxyphenyl) thiazol-2-amine (2b) were coupled with the coupling compound at pH 5. The resultant monochlorotriazine (MCT)-reactive dyes (6a, 6b) were formed. The synthesised dyes were applied onto cotton fabric under typical exhaust dyeing conditions and their dyeing properties were investigated.

Findings

High antimicrobial activity, dye exhaustion and fixation yield on cotton fabric were recorded for each dye. All dyes showed high stability against washing, rubbing, perspiration and light fastness.

Research limitations/implications

Dyeing of cotton fabric with these dyes which have higher fastness, higher exhaustion and higher antibacterial activity is considered one of the most important reactive dyes species.

Practical implications

The preparation procedure showed the synthesis of the novel MCT-reactive dyes derived from thiazole derivatives followed by the application of these dyes on cotton fabrics.

Social implications

Use of reactive dyes will bring a number of benefits to society including higher fastness and higher antibacterial activity so, and these dyes can be used for dyeing cotton.

Originality/value

In this work, the new reactive dyes derived from thiazole derivatives were synthesised and their structures were confirmed by the analytical and spectral data. Such compounds are considered to be excellent reactive dyes with different colour shades and higher antibacterial activity.

Abstract

Purpose

The impact of the coronavirus disease 2019 (COVID-19) pandemic on architectural education (AE) was investigated, and a framework was proposed to reduce the impacts' negative consequences.

Design/methodology/approach

Systematic literature review, bibliometric and content analyses were combined to gain an in-depth understanding of the effects of the pandemic on AE and projections for its future. Relevant documents were extracted from the Web of Science (WoS) database. Bibliometric connections in the context of AE and COVID-19 pandemic were explored using text-mining and content analysis was performed.

Findings

The challenges, development tendencies and collaboration networks in AE during the pandemic were quantitatively and qualitatively analyzed. The most influential articles, journals, authors and countries/regions were highlighted using a bibliometric analysis. The analysis of keyword tendencies and clusters indicates that new concepts have emerged in AE research during the pandemic involving online, in-person and hybrid education. Using content analysis of 57 subtopics, 39 (18) were categorized as having negative (positive) effects. A comprehensive mitigation framework was designed to reduce the impact of the pandemic on AE.

Research limitations/implications

The study findings can enable practitioners to construct effective solutions to COVID-19- and other disaster-related problems regarding AE. The implications, obstacles and mitigation framework presented can help identify gaps in the literature and guide further research.

Originality/value

This paper presents the first bibliometric and content analysis of AE and COVID-19 pandemic-related studies published from January 2020 to June 2022 to highlight several research directions and academic development within the field.

Abstract

The government of UAE helps its nationals to own their private houses. One of the programs that are designed to achieve this goal is the Sheikh Zayed Housing Program (SZHP). It pays grants and loans to nationals to have their own houses. This paper examines the factors that affect the fund allocation of SZHP. The researchers obtained the needed data from the offices of the SZHP. The sample consisted of 394 applicants for the year 2000. Regression models were used to assess the effect of family size, income, marital status and location of the applicants on fund allocation. The research findings show that income, family size and location have the most significant effect on fund allocation.

Abstract

Purpose

Islamic finance is an alternative approach of financial intermediation based on risk-sharing and asset-backed operations, which evolved substantially in recent years in academic research raising the need for quantitative studies to address the intellectual development and scientific performance of this field. This study aims to provide quantitative statistics and comprehensive review of the key influential and intellectual structure of Islamic finance literature.

Design/methodology/approach

The authors apply the trending and cutting-edge quali-quantitative approach of bibliometric citation analysis. This study reviews 1,940 English studies and review papers published in scientific journals indexed by the Scopus database from 1983 to 2019. RStudio, VOSviewer and Excel’s software are used to analyze the collected data and apply the bibliometric tests.

Findings

The results identify the leading academic authors, journals, institutions and countries with relation to Islamic finance. The authors also propose six main research themes in this field, which are as follows: Islamic finance – fundamentals, growth and legitimacy; customer’s attitude and perception toward Islamic finance; accounting and social reporting of Islamic finance; performance and risk management of Islamic finance; Islamic financial markets; and efficiency of Islamic financial institutions. Lastly, the authors identify research gaps in the existing Islamic finance literature and present 24 future research directions.

Research limitations/implications

The data in this study is confined only to the Scopus database of English papers and reviews. It also considers papers directly related to the field of Islamic finance.

Originality/value

To the best of the authors’ knowledge, this paper is one of the first to address the literature of Islamic finance from a bibliometric aspect. The results of this study along with future research questions will help researchers and practitioners to further explore and stand on firm quantitative bases regarding the scientific development of Islamic finance.

Abstract

Purpose

Media has always been used as a key manipulator of public agendas, political beliefs and individuals’ attitudes. The purpose of this study is to investigate the impact of three adaptive media strategies on the pattern and dynamics of potential crowds.

Design/methodology/approach

An agent-based approach is used to simulate the three adaptive media strategies on the pattern and dynamics of potential crowds. During the experiments, the media broadcast is intensified to gather momentum for crowd movements or is lessened to maintain the budget.

Findings

The results show that a slight change in the media management strategy could lead to a radical different impact on the crowd dynamics. The results also show that a quite smart media strategy could outperform a strategy with an unlimited budget. Finally, the structure of the society shows a significant influence on the crowd dynamics than it could be inferred.

Originality/value

The model presents an explanatory toolkit for the crowd complexity. The results provide deep insights into the crowd formation and a basis for understanding the influence of media and the impact of its strategies on the crowd dynamics.

Abstract

Purpose

Problems of Malaysian construction industry have often been associated, in part to incompetent construction manager (CM) when managing the construction projects. Although various education and training provisions have been introduced, critics argue that the provisions have not been effective. Central in the debate on the adequacy of the CM education and training offered is the answer to the question of “what constitutes the technical competency of the CM?” The purpose of this paper is to present the study that identifies the technical competencies required by the CM to address the question.

Design/methodology/approach

Multi-layered thematic analysis of literature was first carried out to identify the technical competency elements. Then, interviews were undertaken to confirm the elements of competencies. It was followed with questionnaire surveys to test the validity of the technical competencies against different contractors’ category and grade/size.

Findings

The findings suggest that the technical competencies of CM are generic, regardless of the size of construction organisation or the types of projects they undertake. A total of 16 CM technical competencies were identified which include the ability to manage: staff, materials, labour, plant, sub-contractors, safety, money, quality, time, environment, site administration, pre-construction activities, project closeout and handover, third parties, computer literacy, and construction contract.

Originality/value

The findings suggest that generic education and training is possible to develop technically competent CM. It also provides insights to the CM technical competencies which the industry is expecting.

Abstract

Purpose

This paper empirically examines the perceived relationship between banking sector performance and FDI inflows, thereby highlighting an underexplored area in the existing literature.

Design/methodology/approach

To provide evidence from the South Asian context, this study selected five economies of the same region based on the data availability. A panel dataset, collected from the internationally reliable sources for the period 1998–2017, is analyzed with the help of different econometric techniques, including pooled least squares, fixed effects, generalized least square and two stages least squares.

Findings

The results indicate a significant negative relationship between banking sector performance and FDI inflows while demonstrating a significant positive association of inflation and trade openness with FDI inflows Moreover, higher per capita income, which is one of the indicators of a growing economy, exerts a statistically significant positive impact on FDI inflows. Finally, institutional factors have not played a significant role in attracting FDI in the sampled countries.

Practical implications

The results demonstrate a unique outcome from the perspective of the relationship between banking sector performance and FDI inflows, and hence policymakers of the developing countries in general and South Asian countries in particular would benefit from the current study significantly.

Originality/value

The obtained results are original as we have provided comprehensive evidence on the relationship between FDI and banking sector performance in the SAARC context for the first time.
