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
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.
