Abstract

Purpose

The purpose of this paper is to present an analytical framework for predicting the residual stresses that result from the laser shock peening of a friction stir‐welded 2195 aluminum alloy sample, using the finite element software LS‐DYNA.

Design/methodology/approach

The pressures resulting from the laser peening are directly applied in an explicit transient analysis as forces. At the completion of the transient analysis, an implicit springback analysis is performed to determine the final residual stresses. This cycle is repeated for the appropriate number of peen applications, including the appropriate overlap of application areas. To validate the analytical framework, a comparison of residual stresses between analysis and a test specimen is made using laser‐peened base material which was not friction stir‐welded. Friction stir welding (FSW) causes residual stresses and material property variations. In this work, the varying material properties regions are simplified and defined as discrete, separate materials. The residual stresses resulting from the welding are introduced directly as initial conditions in the peening transient analysis and so are combined within the analysis with the residual stresses from the peening.

Findings

Comparisons made between the experimental and analytical residual stresses are generally favorable.

Originality/value

Analysis of the laser shock peening of FSW has not been accomplished previously.

Abstract

Purpose

On two different occasions, the Jordanian Constitutional Court has ruled that Articles 51 and 54 of the Jordanian Arbitration Act no. 31 of the year 2001 are unconstitutional and null. In view of this, this paper aims to attempt to give the reader a brief preview of the Jordanian Arbitration Act, the Jordanian Constitution and the Jordanian Constitutional Court. It also highlights and critically analyzes the Jordanian Constitutional Court two decisions pertaining to the Arbitration Act and its special implications in this regard from the perspective of arbitration law and the distinct characteristics embedded in it.

Design/methodology/approach

To examine how effective is the approach followed by the Constitutional Court in ruling the unconstitutionality of the aforementioned Articles, this work makes use of the primary and secondary data available in this regard as the main method to complete such an examination. By critically analyzing and comparing the various data contained in these sources, this work identifies the problems associated with such decisions.

Findings

This work submits that while the Constitutional Court has rested its rulings largely on constitutional principles, concerns arising from the Arbitration Act perspective have not been dealt with adequately by the Court. Furthermore, it argues that while the principles of the constitution shall be respected, the distinct characteristics of the arbitration law warrant a more careful approach than actually followed by the Court.

Originality/value

Taking into consideration the importance of arbitration as an alternative mean for dispute resolution, the Jordanian legislator has addressed the application of arbitration as early as the year 1953. However, while the Constitutional Court’s questionable approach to the aforementioned articles would necessarily hinder the use of arbitration, no comprehensive scholarly work has either examined such approach or addressed its implications. Accordingly, this work derives its originality and value from being the first of its kind to examine and address such a matter.

Abstract

Purpose

The process of predicting construction costs and forecasting price fluctuations is a significant and challenging undertaking for project managers. This study aims to develop a construction cost index (CCI) for Jordan’s construction industry using fuzzy analytic hierarchy process (FAHP) and predict future CCI values using traditional and machine learning (ML) techniques.

Design/methodology/approach

The most influential cost items were selected by conducting a literature review and confirmatory expert interviews. The cost items’ weights were calculated using FAHP to develop the CCI formula.

Findings

The results showed that the random forest model had the lowest mean absolute percentage error (MAPE) of 1.09%, followed by Extreme Gradient Boosting and K-nearest neighbours with MAPEs of 1.41% and 1.46%, respectively.

Originality/value

The novelty of this study lies within the use of FAHP to address the ambiguity of the impact of various cost items on CCI. The developed CCI equation and ML models are expected to significantly benefit construction managers, investors and policymakers in making informed decisions by enhancing their understanding of cost trends in the construction industry.

Abstract

Purpose

This paper aims to investigate the value of information content and informativeness of the analyst report for Sharīʿah-compliant shares in Malaysia.

Design/methodology/approach

The authors use a sample of 657 daily published analyst reports on Sharīʿah-compliant shares from 2010 to 2015, which were downloaded from Bursa Malaysia’s repository system. The method was quantitative in nature and panel regression analysis was used. Diagnostics tests including the variance inflation factor, correlation analysis, heteroskedasticity test, serial auto-correlation and the Hausman test were performed to ensure validity and reliability of data. The significance of the variables indicated whether the analyst reports contained valuable information on Shariah compliancy.

Findings

Results obtained from the FEM-Robust model revealed that the R2 value was equivalent to 0.79 per cent, suggesting that the power of return explained by the information content and informativeness was less for Sharīʿah-compliant shares. The F-statistics were statistically significant for all models, postulating that the data used were reliable and fit for the purpose of analysis. The findings showed that the information content of target price and earnings forecasts significantly influenced the returns of Sharīʿah-compliant shares. In terms of informativeness, return on equity, sales to price ratio and cash flow to price were associated with the returns of the shares.

Practical implications

The outcome from this finding confirmed that the analyst report retained its position as a good source of reference when making investment decisions. However, the disclosure of information in the form of qualitative information together with fundamental information should be enhanced for Sharīʿah-compliant share so that investors would have adequate information when making an investment decision.

Originality/value

This study will supply more insights into the matter of information content and informativeness of the analyst report in Malaysia by focussing on Sharīʿah-compliant shares, which is practically an underexplored research area in Malaysia.

Abstract

Purpose

This study aims to document the influence of information content and the informativeness of analyst reports towards cumulative abnormal return in the Malaysian market.

Design/methodology/approach

Samples of analyst reports for the period 4th January 2010 until 24th December 2015 were collected from the Bursa Malaysia’s repository system for daily basis information. The study uses market-adjusted method for the calculation of cumulative abnormal return and panel regression to test the research objective. In addition, diagnostic tests, which include the variance inflation factor (VIF), correlation analysis, heteroscedasticity tests, serial auto-correlation and the Hausman test, were also performed to ensure the validity and reliability of the data.

Findings

Result from the unbalanced panel data reveals that not all information contained in the analyst reports is able to detect stock returns movement. Only five variables are shown to have a strong association with the returns, and these are target price, earnings forecast, return on equity, cash flows to price and sales to price ratio. The R-square value has also been shown to be relatively low (0.79 per cent), indicating the low predictive power of information content and the informativeness of the analyst report in explaining stock returns. To support the findings based on the knowledge obtained, a descriptive analysis on whether the analyst reports were able to predict the recommendation accurately was performed. Result from the descriptive analysis shows that only 57 per cent of the recommendations are accurate, evidenced by the differing target price and ending price. This outcome appears to contradict the theory of signalling hypothesis. Hence, it can be concluded that analyst reports have less informational role among investors.

Originality/value

This paper has, thus, provided insight into how information disclosed in the analyst report influence the return of stocks, further extending the limited research on analyst report in the context of the Malaysian markets. The paper has also added to the existing literature by providing several implications to practitioners and researchers alike.

Abstract

Purpose

While technical vocational education training (TVET) has been studied in-depth, the evolution and performance patterns of the subject remain unknown and limited. A bibliometric analysis was performed to examine the global scientific literature to assess the state of the art in TVET research over the past 23 years.

Design/methodology/approach

The Web of Science (WoS) database was searched to explore TVET-related research from 1999 to 2021, resulting in the identification of 7,512 articles. The VOSviewer software was used to investigate the network of collaboration between authors, institutions, countries and author keywords.

Findings

The results reveal that the subject categories of “education” and “educational research” are the most prolific contributors to TVET-related research, with 3,314 articles. Most of the previous studies in Phase I (1999–2006) focussed on human capital resources development in the TVET sector. Phase II (2007–2014) follows with the centralisation of TVET, focussing on technology transition in education. However, in Phase III (2015–2021), researchers appear to focus on vocational studies in higher education towards increasing the productivity of human resources via the implementation of technology transition.

Originality/value

The valuable findings of this study can facilitate better understanding among scholars on the trends of TVET research developments and on the direction of future research.

Abstract

Purpose

Previous studies have established to a great extent that regulatory frameworks and, in particular, procurement approaches – that are common in a particular context – have a major impact on the success of building information modelling (BIM) implementation in construction projects. Despite the close links between these two concepts, research on the effect of procurement approaches on BIM implementation is scarce. To address this gap, this paper aims to investigate the barriers that affect BIM implementation through the lens of procurement approaches.

Design/methodology/approach

A mixed-method approach was adopted using a questionnaire survey (n = 116) and interviews with key stakeholders (n = 12) in Jordan. The outcomes of the quantitative parts were augmented with findings from interviews.

Findings

It was revealed that the deployment of unfavourable construction procurement approaches represents a major hurdle towards BIM implementation. Though essential for enhancing BIM implementation, it is revealed that a fundamental change from the common design-bid-build (DBB) to more collaborative procurement approaches remains infeasible in view of the realities that govern the construction industry.

Research limitations/implications

It was revealed the deployment of unfavourable construction procurement approaches represents a major hurdle towards BIM implementation. Though essential for enhancing BIM implementation, it is revealed that a fundamental change from the common DBB to more collaborative procurement approaches remains infeasible given the realities that govern the construction industry.

Originality/value

As the first of its kind, a set of recommendations for establishing supportive, workable procurement that does not deviate significantly from common procedures and practices is presented. Rather than advocating a shift to procurement approaches that are aligned with BIM, the findings offer novel insight into the necessity of developing a framework within the boundaries of the current and widely adopted procurement approaches to address the identified construction procurement issues and facilitate BIM implementation.
