Unmanned aerial vehicles (UAV), colloquially called drones, are widely applied in many sectors of the economy, including the construction industry. They are used for building inspections, damage assessment, land measurements, safety inspections, monitoring the progress of works, and others.

The study notes that UAV pose new, and not yet present, risks in the construction industry. New threats arise, among others, from the development of new technologies, as well as from the continuous automation and robotization of the construction industry. Education regarding the safe use of UAV and the proper use of drones has a chance to improve the safety of work when using these devices.

The procedure (protocol) was developed for the correct and safe preparation and planning of an unmanned aerial vehicle flight during construction operations.

Based on the analysis of available sources, no such complete procedure has yet been developed for the correct, i.e. compliant with applicable legal regulations and occupational health and safety issues, preparation for flying UAV. The verification and validation of the developed flight protocol was performed on a sample of over 100 different flight operations.

The purpose of this study is to identify the factors relating to the integration and compliance of Building Control (Amendment) Regulations 2014 (BC(A)R 2014) in large Irish construction organisations.

To achieve the aim, a mixed method approach is adopted, initially, providing a critique of the literature review, followed by a combination of 7 semi-structured interviews and 30 questionnaires from industry practitioners.

Findings demonstrate that BC(A)R has had a significant positive effect on the industry, eliminating previous bad practice, by increasing the accountability for professionals signing-off on new buildings, and highlights the emphasis on certification in successfully achieving practical completion on projects.

The findings provide further justification on the need for compliance, and integration, of BC(A)R in the Irish construction sector, offering further evidence, where needed, on the benefit of its adoption.

The originality and value of this research lies in the limited number of studies in the area, particularly in the context of large Irish construction projects, which this study aims to fulfil.

The purpose of this paper is to contribute original evidence about the conditions for formal and informal contracts for commodities and labour in the waste economy of a South Indian town.

Field research was exploratory, based on snowball sampling and urban traversing. The analysis follows capital and labour in the sub-circuits of capital generating waste in production, distribution, consumption, the production of labour and the reproduction of society.

Regardless of legal regulation, which is selectively enforced, formal contracts are limited to active inspection regimes; direct transactions with or within the state; and long-distance transactions. Formal labour contracts are least incomplete for state employment, and for relatively scarce skilled labour in the private sector.

The research design does not permit quantified generalisations.

Waste management technology evaluations neglect the social costs of displacing a large informal labour force.

While slowly dissolving occupational barriers of untouchability, the waste economy is a low-status labour absorber of last resort, exit from which is extremely difficult.

The first systematic exploration of formal and informal contracts in an Indian small-town waste economy.

Over the past four decades, China has strived to make the market mechanism play a decisive role in resource allocation under the conditions of adhering to the basic socialist economic system. The paper aims to discuss this issue.

On this matter, this paper proposes a three-phase transition hypothesis for the Chinese institutional change models, namely, a de facto path, which gives potential to a successful incremental transition of a centralized country from planned economy to a market economy, lies in the incremental transitions of the institutional change models from a supply-oriented model at initial reform to a middle-proliferation model and to a demand-induced model along with the gradual establishment of exclusive property rights, thereby completing the transition to a socialist-market-economic system.

The Chinese economic model’s unique connotation is the reason why the solution to this model often baffles both the traditional political-economic logic and western mainstream institutional change theory.

This hypothesis corroborates that China’s unswerving practice of economic reform has provided unprecedented opportunities and challenges for the development of economic theory. The Chinese model constitutes the source of innovation for the subject of Economics with Chinese Studies.

The purpose of this paper is to examine the implications of the COVID-19 pandemic on internal auditing as the pandemic forced individual internal auditors and audit teams to conduct the work remotely.

Five in-depth semi-structured interviews of internal audit experts that work in German retail and manufacturing industry were conducted between February and April 2021.

The authors find that the importance of audit technologies did not change significantly due to the pandemic, as audit technologies were already an integral part of internal audits. Interestingly, the transition to remote audits occurred with remarkable speed and efficiency. The presence of well-functioning information and communication technologies emerges as a critical facilitator for effective remote communication, collaboration and data exchange. However, audit technologies can only partially replace physical on-site examinations and human interaction. The main challenges of remote audits are related to the auditing of non-digitalized processes and the inherent limitations of auditee interviews and interactions.

The authors' interview approach does not allow to cover variations between industries and between countries. While internal audit experts provided notably consistent responses during the interviews, acknowledging that the sample size is very small is important.

The COVID-19 pandemic serves as a catalyst for increased digitalization and technology adoption within the realm of internal auditing. A hybrid approach combining the benefits of on-site and remote audits is expected to prevail in the future.

The paper is among the first to document the effects of the COVID-19 pandemic on the work of internal auditing using field-based research methods.

The purpose of this study is to evaluate the Special Autonomy policy to improve the community welfare of Papua Province.

This study was carried out using a qualitative approach assessing program activities and client satisfaction. It focused on program activity, target and implementation effectively and efficiently, involving the client’s evaluation process. Research data was obtained from the Papua Regional Development Planning Agency and separated into primary and secondary sources. Primary data was obtained through observation, interview and documentation from several informants. The informants were determined based on the role and involvement in the Papua Province Special Autonomy. Secondary data sources were obtained through field studies, scientific journals, previous research, written documents from relevant agencies, internet and electronic and print media.

This study exhibits characteristics of Papua Province Special Autonomy, which are identical to an asymmetric decentralization model, although it took 20 years of implementation because of the lack of evaluation and improvement. It disproves Katorobo’s (2004) theory that the said asymmetric decentralization model is more effective than symmetrical decentralization. Material requirement planning (MRP) empowerment or abolition should be considered important because of the lack of positive results. Otsus needs to improve the system and financial management, considering financial distribution for developed regions in the coastal areas and plains rather than mountainous regions.

This research was conducted because of the phenomenon of Papua Province Special Autonomy, also driven by the problems in the implementation of Special Autonomy Policy for Papua Province that had not borne optimum results. This study aimed to make recommendations for the Special Autonomy policy of the Papua Province to improve community welfare.

This paper aims to evaluate the quality control systems for constructions in seven countries in Europe with the purpose to trace innovative approaches and best practices that can serve as examples for other countries.

The paper is based on a series of research projects carried out over a number of years. The research results were updated in 2016 with a desktop research project in seven European countries. The results from this latest project form the heart of this paper. The information is organised into tables that describe and analyse the main features of the quality control systems of the countries (e.g. scope, focus and main characteristics of the procedures and quality demands on building professionals).

Several similar trends can be recognised in the quality control systems of the various European Union (EU) countries. Quality control is getting more and more privatised and the control framework is setting checks and balances throughout the construction process. Other findings are that scope and focus of the statutory control is unbalanced. Within the control processes emphasis is put on the safety aspects of complex constructions. Far fewer demands are made on the quality of the builders. Re-orientation of the building regulatory framework seems to be needed.

The paper only focusses on European countries where private quality control is established and on selected topics. The findings are based on desktop research and not on the practical experiences of the stakeholders involved in the countries studied.

The paper draws some important recommendations for policymakers in the building regulatory field. It suggests both an enhancement of the effectiveness of the quality control procedure as well as the commitment of builders to comply with the regulations.

The quality of constructions is essential for the wellbeing and safety of its users, its occupants or its visitors. This applies to the whole range of quality aspects: structural- and fire safety, health, sustainability and usability aspects. The analyses and recommendations of this paper aim to contribute to an improvement of the overall construction quality.

The paper makes an original contribution to the (limited) literature that is available in this field. The results can be used to situate the quality control systems of each member state within the EU, to assess the main trends, and it can be used as a guide to develop strategic choices on possible improvements in each country.

An accurate detection of overhead ground wire under open surroundings with varying illumination is the premise of reliable line grasping with the off-line arm when the inspection robot cross obstacle automatically. This paper aims to propose an improved approach which is called adaptive homomorphic filter and supervised learning (AHSL) for overhead ground wire detection.

First, to decrease the influence of the varying illumination caused by the open work environment of the inspection robot, the adaptive homomorphic filter is introduced to compensation the changing illumination. Second, to represent ground wire more effectively and to extract more powerful and discriminative information for building a binary classifier, the global and local features fusion method followed by supervised learning method support vector machine is proposed.

Experiment results on two self-built testing data sets A and B which contain relative older ground wires and relative newer ground wire and on the field ground wires show that the use of the adaptive homomorphic filter and global and local feature fusion method can improve the detection accuracy of the ground wire effectively. The result of the proposed method lays a solid foundation for inspection robot grasping the ground wire by visual servo.

This method AHSL has achieved 80.8 per cent detection accuracy on data set A which contains relative older ground wires and 85.3 per cent detection accuracy on data set B which contains relative newer ground wires, and the field experiment shows that the robot can detect the ground wire accurately. The performance achieved by proposed method is the state of the art under open environment with varying illumination.

Effective rail surface defects detection method is the basic guarantee to manufacture high-quality rail. However, the existed visual inspection methods have disadvantages such as poor ability to locate the rail surface region and high sensitivity to uneven reflection. This study aims to propose a bionic rail surface defect detection method to obtain the high detection accuracy of rail surface defects under uneven reflection environments.

Through this bionic rail surface defect detection algorithm, the positioning and correction of the rail surface region can be computed from maximum run-length smearing (MRLS) and background difference. A saliency image can be generated to simulate the human visual system through some features including local grayscale, local contrast and edge corner effect. Finally, the meanshift algorithm and adaptive threshold are developed to cluster and segment the saliency image.

On the constructed rail defect data set, the bionic rail surface defect detection algorithm shows good recognition ability on the surface defects of the rail. Pixel- and defect-level index in the experimental results demonstrate that the detection algorithm is better than three advanced rail defect detection algorithms and five saliency models.

The bionic rail surface defect detection algorithm in the production process is proposed. Particularly, a method based on MRLS is introduced to extract the rail surface region and a multifeature saliency fusion model is presented to identify rail surface defects.

The purpose of this study is to contribute to the research related to “the interplay between accounting and the state, politics, and local authorities in the broad government and administration of food for sustainability of populations” (Sargiacomo et al., 2016). Considering contemporary examples and investigating the genealogy of an 18th-century reform of fishery management (the New Plan), the authors explore the role played by accounting and calculative practices when local authorities intervene using forms of discipline based on control systems that acted on commons (fish), people and space.

This paper is historically grounded on archival research on a fish provisioning case during the 18th century in Ancona, an Italian town on the Adriatic coast. The investigation adopts an approach focussed on the use of disciplinary methods in the terms highlighted by Foucault. This perspective offers a lens capable of revealing the key role of accounting in a period when discipline became “general formulas of domination” (Foucault, 1977) and the Papal States were looking for food provisioning solutions (Foucault, 2007). The study highlights similarities with contemporary fishery management.

The paper shows that governability of fishery in a commons' logic is not limited by the properties of the good, but rather “it is achieved through the objects and instruments that are deployed to make it possible” (Johnsen, 2014, p. 429). It reveals forms assumed by economic calculation in different eras and their contribution in the art of governing realised by the state (Hoskin and Macve, 2016). The study unveils how accounting effectively operates using “naming and counting” activities (Ezzamel and Hoskin, 2002) based on a system of documents and accounting registers; these have a pivotal role in redefining fishery management and in keeping goods (fish) and people (fishermen) under control. The investigation also highlights the importance of properly quantifying data in fishery management, confirming the literature on the topic (Beddington et al., 2007, p. 1713). In contemporary situations, data refer to quantifying the fish stock in the sea and the consequent estimation of fish catch. In the historical investigation, although environmental protection was not an issue, quantification refers to the fish that entered the town of Ancona, whose estimation was the result of a new calculative approach adopted by local authorities facing fish needs. In addition, it offers early evidence of organised and rational-based control mechanisms that were the result of Enlightened ideas emerging in the Papal States context.

Despite the fact that fish represent a fundamental good for governments to act on in response to a population's needs, there has been no attention paid to how governmental authorities have used disciplinary mechanisms to intervene in fishery management or the role played by accounting. This study's novelty is its investigation of fishery, using Foucauldian disciplinary methods to understand accounting's contribution in fishery governance. In addition, this investigation permits to unveil the role of accounting to support one of the main principles of the governance of commons that is represented by the congruence between rules and local conditions (Fennell, 2011, p. 11; Ostrom, 1990, p. 92).
