The purpose of this paper is to investigate the influence of surface topology on the performance of laser line scanning probe and to suggest methodology for 3D digitization of specular surfaces.

Two different molds, one having milled surface and the other with polished surface, were used to identify effect of surface characteristics on the performance of laser line scanning probe mounted on bridge-type coordinate measuring machine. The point cloud data acquisition of two surfaces was carried out using different combinations of laser scanning parameters. The point cloud sets thus obtained were analyzed in terms of completeness, noise and accuracy. The polished mold which exhibited specular reflection was digitized at different scanning angles of laser line scanning probe using the best combination of scanning parameters.

Results confirmed that surface characteristics play important role to determine quality of the reverse engineering (RE) process. The results in terms of completeness, accuracy and noise for point cloud sets have successfully been obtained for milled and polished surfaces. Three-dimensional (3D) comparison analysis suggested larger deviation in cases of polished surface as compared to milled surface. The point cloud set acquired with proposed approach was better in terms of both completeness and noise reduction.

There has been an increased demand for measurement of metallic, polished and shiny surfaces in automotive, aerospace and medical industries. These surfaces are very difficult to scan because they exhibit specular reflection instead of diffuse reflection. Laser line scanning probe which is a non-contact method is in great demand for RE. This is due to the fact that it possesses very high data acquisition speed. However, laser scanning is hugely affected by surface characteristics which in turn govern specular reflection.In this paper, it has been shown that a surface that exhibits various degrees of specular reflection can be digitized efficiently if appropriate combination of scanning parameters and positions of laser line scanning probe are used. Also, this paper has attempted to offer a procedure to overcome incompleteness and noise in 3D data as obtained by the laser line scanning probe.

Statements by Lord Denning, M.R., vividly describing the impact of European Community Legislation are increasingly being used by lawyers and others to express their concern for its effect not only on our legal system but on other sectors of our society, changes which all must accept and to which they must adapt. A popular saying of the noble Lord is “The Treaty is like an incoming tide. It flows into the estuaries and up the rivers. It cannot be held back”. The impact has more recently become impressive in food law but probably less so than in commerce or industry, with scarcely any sector left unmolested. Most of the EEC Directives have been implemented by regulations made under the appropriate sections of the Food and Drugs Act, 1955 and the 1956 Act for Scotland, but regulations proposed for Materials and Articles in Contact with Food (reviewed elsewhere in this issue) will be implemented by use of Section 2 (2) of the European Communities Act, 1972, which because it applies to the whole of the United Kingdom, will not require separate regulations for England and Wales, Scotland and Northern Ireland. This is the first time that a food regulation has been made under this statute. S.2 (2) authorises any designated Minister or Department to make regulations as well as Her Majesty Orders in Council for implementing any Community obligation, enabling any right by virtue of the Treaties (of Rome) to be excercised. The authority extends to all forms of subordinate legislation—orders, rules, regulations or other instruments and cannot fail to be of considerable importance in all fields including food law.

This study aims to analyze the definition and contextual variations of homo islamicus in literature across disciplines, including beyond Islamic economics, and to explore their implications for Islamic economic agents.

Using a machine learning-based text analysis approach, 61 articles will be examined to classify definitions and identify contextual clusters for homo islamicus.

This study reveals eight classifications of homo islamicus definitions and three distinct contexts. These findings suggest significant divergence between the concept of homo islamicus in Islamic economic tradition and its interpretation by non-Islamic scholars, attributable to underlying values and ideologies rather than methodological differences.

This study focuses solely on textual analysis of articles using the term “homo islamicus” across disciplines, precluding the formulation of epistemological and ontological frameworks. Future research could expand on these aspects.

By presenting diverse perspectives on homo islamicus, this paper facilitates a more comprehensive understanding among scholars of Islamic economics, aiding in the resolution of disagreements within the field.

This study introduces novel classifications of homo islamicus definitions and contextualizes them, providing insights into their implications for Islamic economic agents.

The reasons behind the project management failure of higher education institutions (HEIs) have been researched for the past few years. One of the reasons is the lack of tools to integrate their knowledge process capabilities (KPC) with their project management (PM) to measure maturity by assessing these capabilities. Various project management maturity (PMM) models exist. Yet, there is a limited number of empirical studies that support the four integrations of KPC and PMM. Therefore, this study aims to propose a new heretical model, namely, KPC-knowledge management (KM) and evaluates a research model that includes the four KPC as an antecedent to PMM.

The suggested research model is assessed by using partial least squares structural equation modeling. Furthermore, the study's hypotheses were examined based on a sample of 352 respondents from the project management departments in 10 public universities in Yemen.

Analysis revealed that the derived PMM status could be benchmarked with the project management maturity model. Also, the study found that integrating the KPC into PM enables the institutions to perform critical tasks and value chain activities and enhance the PM maturity level as well. In contrast, if one of the capabilities does not positively impact PMM, it affects the maturity level of the entire project.

The findings are obtained concerning data collected from public universities and represent the Yemeni context, limiting the generalization on a different geographical area. Also, this proposed model can be evaluated in a practical way like conducting a focus group, a set of interviews with specialists, a case study or action research. The qualitative research will help academics to validate our proposal for future research purposes.

The proposed approach may be adapted to the characteristics of organizations involved in projects as external performers (project-based organizations) and not just the HEIs projects. This study provides managers and policymakers with insights into assessing PMM and improving their organizational effectiveness when deciding which KPCs to focus on in the future.

This study contributes to the current PM awareness in Yemen and facilitates its success using the knowledge processes capabilities in Yemen's HEIs. It encourages organizations to take this opportunity to revive the projects and achieve a maximum level of maturity.

This study provides new insights into two domains through the link between knowledge management and PM. To the best of the authors' knowledge, this paper is among the first to empirically study the impact of the four KPC toward PMM. It enriches the theoretical perspective of PM. Also, it contributes to the literature on the success factor of KPC, which can be considered to improve organizational performance.

This paper aims to develop a performance measure for Islamic banks (IBs) by harmonizing related studies. Furthermore, this work uses the developed yardstick to analyze the performance of a sample of 11 IBs from across different countries.

This paper uses the mix-mode method. The qualitative approach is engaged first to construct the IBs performance yardstick. Following this, the quantitative approach is applied through the use of the performance yardstick to measure the sample’s performance.

This study develops a maqāṣid-based performance yardstick adapted from previous works. The developed model in this study is called an integrated maqāṣid al-Sharīʿah--based performance measure (IMSPM). By using this performance measure, the present paper finds that the sample performed highest on the objective of nafs (self) over the three-year period. In addition, this study identifies the information which best indicates the sample’s performance during the analysis.

This paper uses the sample’s annual reports. The analysis is thus limited to informational disclosure.

Islamic banking and financial institutions may use the IMSPM to communicate a measurable report on their promotion of the maqāṣid al-Sharīʿah (objectives of Islamic law).

The evidence from 11 IBs is indicative of their efforts to realize maqāṣid al-Sharīʿah in the banking industry. This point may best challenge the practice of stigmatizing IBs for not being in line with the Sharīʿah (Islamic law) or of imitating conventional banks.

The novelty of this study lies in two points. First, this study harmonizes previous works to integrate financial and religious measures in a single yardstick. Second, by using the developed standard, this study offers a fresh insight into the global IBs’ performance, represented by 11 IBs worldwide.

This paper aims to systematically review the concept of homo Islamicus discussed in the existing literature. The second objective is to offer a set of criticisms of the descriptions of homo Islamicus.

In this paper prespecified eligibility criteria are applied to select articles that are indexed in Scopus and ProQuest, or published by two major publishers, ScienceDirect and Emerald, or appear on ResearchGate. A set of books related to homo Islamicus was also used as secondary sources to support the selected articles. As a result, this paper systematically reviews 53 articles and four books to synthesize the homo Islamicus.

There are four notions of homo Islamicus: Firstly, homo Islamicus as the kind of economic agent that is required to achieve Islamic economic objectives. Secondly, homo Islamicus as a defining factor that makes the difference between Islamic and conventional economics. Thirdly, homo Islamicus as an economic agent whose characteristics are something Islamic economics aims to realize. Lastly, homo Islamicus as an economic agent representing the fundamental assumption in Islamic economics.

Mapping homo Islamicus can be helpful for future researchers to conduct analyses related to homo Islamicus, especially in the context of empirical studies of the existence of homo Islamicus in economic reality. This literature review can help other researchers to understand the development of literature related to homo Islamicus.

This paper seems to be the first to systematically identify, select and synthesize the description of homo Islamicus in the literature.

Cash waqf is a powerful financial instrument that deals with the issue of liquidity constraints in waqf institutions. While there are several models of cash waqf operating in different countries, there is increasing demand for innovative cash waqf models, especially within the financial technology context. This paper aims to propose a practical alternative model of funding for waqf institutions using the concepts of crowdfunding and cash waqf.

This study evaluated the literature relevant to cash waqf models that have been implemented in different countries and proposed a new viable alternative model.

Results offer an alternative financing model, named crowdfunding cash waqf model, for waqf institutions to overcome monetary constraints and enable development projects to be completed.

The current study has important implications for both officials and relevant stakeholders. It is sought to bring better consistency between cash waqf donors, solving the liquidity problem faced by waqf institutions, enhancing the transparency of waqf institutions and their use of waqf funds, wealth circulation and financing businesses without interest-based loans (riba). By incorporating a crowdfunding and investment mechanism in the model, this method of collecting funds will assist governments in reducing their expenditure on waqf institutions and other social development programmes.

The proposed model differs from current methods of generating cash waqf, including those are also internet-based. The proposed model is devised to help waqf institutions achieve financial sustainability by including an investment mechanism in the model to sustain the development of waqf projects.

“Consumerism”, for want of a better description, is given to the mass of statutory control (which shows no sign of declining) of standards, trading justice to the consumer, means of redress to those who have been misled and defrauded, advice to those in doubt; and to the widespread movement, mostly in the Western world, to achieve these ends.

This paper aims to investigate the subject matter of Islamic economics that will be the object of a study as a discipline by classifying and unifying different approaches proposed by Islamic economists.

The paper is a conceptual paper using discursive analysis analysing the perspective and approaches proposed by Islamic economists in defining economic problems from an Islamic perspective. The perspective and approaches proposed are classified and analysed for their implications in constructing the subject matter of discipline.

Islamic economics, as a new body of knowledge, needs to clarify the economic problems that will be its subject matter. The paper brings an insight into the subject matter of Islamic economics as conceived by scholars in two approaches, namely, economic problems “as they are” and economic problems “as they should be”. The paper also proposes a unified perspective in defining the subject matter of Islamic economics for further development of the discipline.

This paper only provides philosophical guidance for researchers in mapping the problems and the goals of the policy being studied, although it does not offer any practical use for policymaking as each policy is faced with different and specific cases. This paper may be used to assist future researchers in shaping other unexplored fields in Islamic economics as a body of knowledge.

Islamic economics as a discipline will be strengthened if it has a clear subject matter that will be the object of study. However, the conception of economic problems proposed by Islamic economists is based on life-reality, i.e. of what human beings face in their life (practical-type economic problems as they are) and based on life guidance from the Qur’an on how human beings should live as well as life-objectives, i.e. of what goals he should strive for (ideal-type economic problems as they ought to be) brings implication that there are differences in determining the object of study of Islamic economics.

This paper promotes the unification of two conceptions of economic problems proposed by scholars by defining Islamic economics as “a study of resource appropriation to realize human well-being (maslahah)”. This suggests that economic problems as manifested in life reality will be studied within the grand objective of life in Islam (maqasid al-Shariah), and economic problems as perceived in life goals will be studied in the context of life reality. Islamic economic theory will be formulated not only to solve the apparent problem of “what is” but also formulated in a way that refers to goals (ideals) of “what ought to be” that will provide solutions to current economic problems according to certain vision and to take steps to move in that visionary direction.

Building operations and human activities indoors continuously affect air quality, contaminating the air and sometimes exceeding permissible limits which can be health threatening either in the short or long time. This implies a need for strict awareness and compliance with air quality standards, particularly in workplaces prone to air contaminants emissions. This study aims to evaluate printing-related pollutant concentrations and their effects on indoor air quality (IAQ). The study investigated a printing press's total volatile organic compounds (TVOC), particulate matter (PM), carbon monoxide and carbon dioxide emissions.

This study used mainly an experimental research design supported by physical assessment by identifying the major printing-related pollutants, assessing the existing situation and measuring pollutant concentration levels using literature reviews, walkthrough inspections and experiments, respectively. The measurements were conducted in two scenarios: with and without printing activities, and the results were compared with relevant standards and guidelines.

The outcomes indicate that TVOC concentration reaches 120 ppb during printing and binding activities, exceeding the 75 ppb acceptable limit based on the time-weighted average. The PM2.5 concentrations reach 49 µg/m³ and PM10 up to 150 µg/m³, exceeding acceptable levels given by the US Environmental Protection Agency (EPA), which are 35 µg/m³ and 150 µg/m³ for PM2.5 and PM10, respectively. These high concentrations of TVOC and PM indicate a significant risk to the health of building occupants, particularly those with respiratory conditions. PM concentrations do not exceed permissible levels when no printing or bookbinding occurs, suggesting that printing-related activities can contribute to elevated TVOC and PM concentrations.

The social implication of the study lies in its ability to promote awareness among workers and improve their well-being which in turn relates to productivity. The study outcome could also encourage businesses to adopt more responsible environmental and social practices as part of corporate social responsibility practices.

The study's findings, which highlight the need for improved ventilation in printing halls, have the potential to significantly benefit building system designers, facility managers, policymakers and decision-makers. By providing information and theoretical support, the research can help integrate policies that regulate IAQ by reducing pollutant concentrations. This protects workers' health and helps update and enforce stricter IAQ regulations for industrial operations.
