Abstract
Purpose
The purpose of this paper is to show how the time frame for the execution of a construction project in Algeria is rarely respected because of organizational problems and uncertainties encountered while the execution is underway.
Design/methodology/approach
A case study on the construction of a metro station is used as a pilot project to show the effectiveness of replacing traditional construction processes by more innovative procedures. Concurrent engineering (CE) is applied to optimize the execution time of the underground structure. A numerical simulation is integrated into the construction process in order to update design parameters with real site conditions observed during the construction process.
Findings
The results show that the implementation of CE is efficient in reducing the completion time, with an 18 per cent reduction observed in this case study. A cost reduction of 20 per cent on the steel frame support and a total cost reduction of 3 per cent were obtained.
Research limitations/implications
The study demonstrates that the application of CE methods can be quite valuable in large, complex construction projects. Vulgarizing it as “the solution” to adjust time frame delay, control quality and cost, might be an issue for local construction enterprises in Algeria.
Originality/value
Using the concept of CE by overlapping different activities involved in a construction project and making use of simulation tools in the process at different stages of the execution have resulted in modifying the excavation method and hence reducing the completion times.

Abstract
Purpose
The purpose of this paper is to report the results of an investigation into individual investors' perceptions of the factors affecting buying, holding and selling of stock on the Bahrain stock exchange (BSE). Additionally, the paper investigates the perceptions of individual investors about corporate financial statements as a source of information for individual investors' investment decisions and what specific information such investors would like firms to disclose in these reports.
Design/methodology/approach
The research method involved a mail questionnaire sent to 800 individual investors. The response rate was 42.6 percent. This research method was complemented by a series of field interviews conducted with 20 investors and six stockbrokers for the purpose of gaining additional insights into the topic.
Findings
The study found that individual investors perceived corporate financial statements as the most important source of information for their investment decisions. The results also show a relatively high degree of agreement within the groups (both large and small) as to the ranking in terms of the importance of the topics. Overall, the study found relatively high levels of consensus between the two user‐groups with regards to the majority of questions investigated. The greatest difference between the user‐groups regards the perception of the relative importance of the cash‐flow statement, the income statement and which information items are needed for investors' decision making.
Originality/value
The paper offers rich data on the perceptions and uses of financial and non‐financial information by individual investors. This is the first time this type of research has been conducted in Bahrain.

Abstract
Purpose
This study aims to assess the mediating effect of sustainable competitive advantage (SCA) on the relationship between organisational innovativeness (OI) and performance of small- and medium-sized enterprises (SMEs) operating in Konya, Turkey.
Design/methodology/approach
A survey method is used to collect the necessary data for this research. A total of 264 respondents from 83 SMEs partook in the study. In choosing the sample size, both purposive sampling and simple random techniques are used. The data gathered are analysed using SPSS program and Hayes PROCESS macro v.3.4.1.
Findings
The results of the analyses reveal that OI has a statistically significant positive effect on SCA and firm performance (FP). Moreover, SCA is found to have a mediating effect on the relationship between OI and FP.
Practical implications
Policymakers and management of SMEs need to show great commitment to innovativeness and relate it to SCA to create superior customer value, thereby leading to a holistic and long-term FP.
Originality/value
This study brings to the fore empirical evidence on how SCA serves as a mediator between OI and FP. It also contributes to the literature by focusing on three distinct but related variables. The study makes theoretical contribution by highlighting the role of the resource-based theory in enhancing business performance and SCA through strategic internal resources and innovative activities.

Abstract
Achieving continuous innovation performance still poses a major challenge to established companies as it requires high flexibility and adaptability in usually efficiently structured organisations. One way to tackle this challenge lies in establishing effective behaviours to successfully establish and apply innovation leadership mechanisms in an organisation. The emerging agile leadership style could provide such effective behaviours, as it addresses the demand for flexibility and adaptability on the organisational level. Despite these clear parallels research on the link between agile leadership and innovation leadership, and their possible combined contribution to drive continuous innovation performance is still in its infancy. Accordingly, the present study examines the behaviours of agile leaders to promote continuous innovation in established companies. It applies a discovery-driven research process of agile leaders to derive and categorise their behaviours. The subsequent comparison of the identified agile leadership behaviours with innovation leadership mechanisms from existing literature leads to eight specific, combined agile leadership principles within the three categories empowerment, performance enhancement, and support for continuous innovation. Eventually, this basis allows the conceptualisation of a first exploratory framework with the identified behaviours as possible enablers, and innovation leadership mechanisms as possible mediators for the continuous innovation performance, subject to test. These findings enhance existing theory by clarifying a possible link between agile leadership and continuous innovation. That way, practitioners can profit from concrete principles for agile leaders to inspire and enable continuous innovation in individuals and teams.

Abstract
Purpose
The Ottoman cultural legacy in Algeria is made up of a diverse range of architectural structures. The Algerian government strategy in connection with the Ottoman old buildings is to restore them into museums. This study will attempt to present a contrastive analysis between two old palaces being under restoration (refurbishment), and the goal is to propose a museum route by calculating the ambiance aimed at circulating the rooms by visitors.
Design/methodology/approach
The authors analyzed the architectural components of the various entities by observing in situ and taking measurements for a single case study to get a sense of the results for the mid-season (spring and fall). The configuration was next evaluated by modeling the space syntax and combining it with a simulation of daylight luminance, for the period when the authors could not make measurements on-site. The ultimate goal is to combine these findings to suggest the ideal in-route for the future museum.
Findings
This research allowed the authors to propose a museum itinerary adapted to the new vocation of the palaces, which considers the daylight as an element of composition in the spaces of circulation.
Practical implications
The paper proposes solutions to a flow management problem encountered in several similar palaces converted into museums.
Social implications
The study aims to raise questions on the museum, and to preserve such heritage from neglect by giving it a new life more adapted to the needs of the Algerian society.
Originality/value
The authors believe that this contribution will be a creative solution for issues related to the operation of palaces that have been converted into museums.

– The purpose of this study is to examine if the cash flow and short-term accruals and long-term accruals together have a role to play in explaining the change in dividends.
Abstract
Purpose
The purpose of this study is to examine if the cash flow and short-term accruals and long-term accruals together have a role to play in explaining the change in dividends.
Design/methodology/approach
The authors’ mainly used the same models developed by Atieh and Hussain (2008) and expanded on this model by including contextual factors: firm growth, firm size, gearing and quality of earnings. Using 344 observations from Jordanian firms, the association of variables with dividend changes was analyzed using the generalized least square regression.
Findings
The results reveal consistency with previous studies that disaggregated earnings outperforms the cash flow model in explaining the changes in dividends. Also, the explanatory power of the Lintner (1956) model is improved by replacing earnings with cash flow and short-term and long-term accruals, which is in line with previous studies. Regarding the effect of contextual factors, the superiority of the accrual model is affected by the contextual factors proposed, except for geared firms. The accrual model is superior for high growth, large firms and poor quality of earnings.
Originality/value
The paper contributes to the existing literature that the Lintner (1956) model’s explanatory power can be improved by replacing earnings with its components mainly cash flows and short-term and long-term accruals. These results support the evidence related to developed markets. The paper also provides evidence of the importance of firm characteristics on the information content of the components of earnings.

Abstract
Purpose
The purpose of this paper is to present the preparation of core-shell ferrites/kaolin pigments and comparing their efficiency in protecting metal substrates to original ferrites which were also prepared. Core-shell structured particles are recently gaining lots of importance due to their exciting applications in different fields; these particles are constructed from cores and shells of different chemical compositions which show ultimately distinctive properties of varied materials different from their counterparts. The new core-shell pigment is based on shell of different ferrites that comprises only 10-20 per cent of the whole pigment on kaolin (cores) which is a cheap and abundant ore that comprises 80-90 per cent of the prepared pigment. The new pigments do not only comprise two different components, but they also contain pigment and extender in the same compound; their loadings in the paint formulations ranges from 50 and 75 per cent of the whole pigment. The work showed that these eco-friendly and cheap core-shell pigments are comparable in their efficiency to that of ferrites in protecting steel substrates.
Design/methodology/approach
The different ferrites and ferrites/kaolin pigments were characterized using different analytical and spectrophotometric techniques, such as X-ray fluorescence, X-ray diffraction (XRD), scanning electron microscopy/energy-dispersive X-ray (SEM/EDAX) and transmission electron microscopy (TEM). Evaluation of these pigments was done using international standard testing methods (ASTM). After evaluation, the pigments were incorporated in solvent-based paint formulations based on medium oil-modified soya-bean dehydrated castor oil alkyd resin. The physico-mechanical properties of dry films and their corrosion properties using accelerated laboratory test in 3.5 per cent NaCl for 28 days were determined.
Findings
The results of this work revealed that ferrite/kaolin core-shell pigments were close in their performance to that of the ferrite pigments in protection of steel, and at the same time, they verified good physico-mechanical properties.
Practical implications
Treated kaolin can be applied in many industries beside pigment manufacture and paint formulations; it can be applied as reinforcing filler in rubber, plastics and ceramic composites. Also, it is applied in paper filling, paper coatings and electrical insulation.
Originality/value
Ferrite and ferrite/kaolin are environmentally friendly and can replace other hazardous pigments (e.g. chromates) with almost the same quality in their performance; also, they can be used in industries other than paints, for example paper, rubber and plastics composites.

Abstract
The purpose of this article is twofold: to identify the characteristics of research on organisation and management in Arab countries and to find out whether research results support the culture‐free hypothesis or not. A thorough search of sixteen journals, research monographs, books and theses produced only 35 empirical studies. Most of these studies were exploratory, descriptive, and used small convenient samples. Although some findings supported the culture‐bound hypothesis, major conceptual and methodological weaknesses in these studies throw doubt upon the validity of their results.
