Abstract

Purpose

Procuring relief products and services is a challenging process for humanitarian organizations (HOs), yet it accounts for approximately 65% of relief operations’ costs (Moshtari et al., 2021). This paper aims to examine how procurement internal controls, materials and purchasing procedure standardization influence information integration and procurement performance.

Design/methodology/approach

In this study, partial least square structural equation models and multigroup analysis were used to analyze data collected from 170 HOs.

Findings

Procurement internal controls and material and purchasing procedure standardization fully mediate between information integration and procurement performance.

Research limitations/implications

The study focuses only on HOs. Since humanitarian procurement projects take place over a period of several years, it is difficult to capture the long-term effects of information integration, procurement internal controls, material and purchasing procedure standardization and procurement performance. In this regard, a longitudinal study could be undertaken, provided that the required resources are available.

Practical implications

Procurement managers should implement information integration practices within acceptable procurement internal controls and standardize material and purchasing procedures to boost procurement performance.

Originality/value

By integrating information through procurement internal controls and standardizing material and purchasing procedures, procurement performance in a humanitarian setting can be systematically optimized.

Abstract

Purpose

Authorization and access control have been a topic of research for several decades. However, existing definitions are inconsistent and even contradicting each other. Furthermore, there are numerous access control models and even more have recently evolved to conform with the challenging requirements of resource protection. That makes it hard to classify the models and decide for an appropriate one satisfying security needs. Therefore, this study aims to guide through the plenty of access control models in the current state of the art besides this opaque accumulation of terms meaning and how they are related.

Design/methodology/approach

This study follows the systematic literature review approach to investigate current research regarding access control models and illustrate the findings of the conducted review. To provide a detailed understanding of the topic, this study identified the need for an additional study on the terms related to the domain of authorization and access control.

Findings

The authors’ research results in this paper are the distinction between authorization and access control with respect to definition, strategies, and models in addition to the classification schema. This study provides a comprehensive overview of existing models and an analysis according to the proposed five classes of access control models.

Originality/value

Based on the authors’ definitions of authorization and access control along with their related terms, i.e. authorization strategy, model and policy as well as access control model and mechanism, this study gives an overview of authorization strategies and propose a classification of access control models providing examples for each category. In contrast to other comparative studies, this study discusses more access control models, including the conventional state-of-the-art models and novel ones. This study also summarizes each of the literature works after selecting the relevant ones focusing on the database system domain or providing a survey, a classification or evaluation criteria of access control models. Additionally, the introduced categories of models are analyzed with respect to various criteria that are partly selected from the standard access control system evaluation metrics by the National Institute of Standards and Technology.

Abstract

Purpose

This study aims to propose an adaptive fractional-order sliding mode controller to solve the problem of train speed tracking control and position interval control under disturbance environment in moving block system, so as to improve the tracking efficiency and collision avoidance performance.

Design/methodology/approach

The mathematical model of information interaction between trains is established based on algebraic graph theory, so that the train can obtain the state information of adjacent trains, and then realize the distributed cooperative control of each train. In the controller design, the sliding mode control and fractional calculus are combined to avoid the discontinuous switching phenomenon, so as to suppress the chattering of sliding mode control, and a parameter adaptive law is constructed to approximate the time-varying operating resistance coefficient.

Findings

The simulation results show that compared with proportional integral derivative (PID) control and ordinary sliding mode control, the control accuracy of the proposed algorithm in terms of speed is, respectively, improved by 25% and 75%. The error frequency and fluctuation range of the proposed algorithm are reduced in the position error control, the error value tends to 0, and the operation trend tends to be consistent. Therefore, the control method can improve the control accuracy of the system and prove that it has strong immunity.

Originality/value

The algorithm can reduce the influence of external interference in the actual operating environment, realize efficient and stable tracking of trains, and ensure the safety of train control.

Abstract

Purpose

The purpose of this paper is to explain how public sector accounting has changed and is changing due to public governance development.

Design/methodology/approach

This paper conducts a traditional literature review based on selected studies in the fields of accounting, public administration and management. The aim of the review is to explain how diverse forms of public governance influence the fate of public sector accounting, including accountability, performance measurement, budgeting and reporting practices.

Findings

Public governance is developing into more inclusive but also complex forms, resulting in network, collaborative and digital governance. Consequently, the focus and practices of public sector accounting have changed, as reflected in new types of accountability, performance measurement, budgeting and reporting practices.

Research limitations/implications

Drawing upon literature from different fields enables a deeper understanding of the changes in public sector accounting. Nevertheless, the intention is not to execute a systematic literature review but to provide an overview and resolve the scattered body of knowledge generated by previous contributions. The areas of risk management and auditing were not included and deserve further attention.

Originality/value

This paper discusses the need to continually redefine and reassess public sector accounting practices, by recognising the interdependencies between different actors, citizens and digital technologies.

Abstract

Purpose

The intra-organisational relationships of through-life support services providers are complex, especially given the multifaceted nature of the provision required. For example, capabilities within the UK highways maintenance arena must support engineering design, routine maintenance and the on-going management of the network. While collaboration in construction projects has formed a major research focus in recent years, there is a paucity of work examining collaboration in-flight.

Design/methodology/approach

Through a micro-practices approach, two contracts delivering highway infrastructure maintenance and renewal services are examined to explore the intra-organisational relationships that determine the quality of service delivered.

Findings

Despite the rhetoric of collaboration and integrated working that pervades the contemporary project discourse, there was a clear focus on addressing immediate technical and commercial concerns, rather than on creating the conditions for integrated working to flourish. On the occasions where the collaborative environment was prioritised, a more integrated service was delivered.

Originality/value

In contrast to other accounts of the ways collaborative working shapes performance, this research reveals an acute need for a sustained collaborative effort; as soon as “collaborative working” was normalised, the level of integration and seamlessness of service was diminished. This questions normative notions of what defines collaborative working in projects and suggests a need for re-framing it as an on-going accomplishment of actors involved. Such a perspective resonates with notions of “organizational becoming”, particularly in that attempts to foster collaboration are themselves constitutive of the unfolding and shifting nature of intra-organisational relationships that emerge in complex contractual arrangements.

Abstract

Purpose

In the democratic digital environment, brand managers frequently deal with the unauthorized use of the brand by third parties. The phenomenon, known as brand hijacking, has been treated in different and sometimes conflicting ways in the academic and professional literature. The aim of this paper is to clarify the meaning of brand hijacking and to shed light on the various motivations and intentions underpinning the phenomenon.

Design/methodology/approach

A Delphi-based survey among both academic and professional experts was conducted to explore the key features of brand hijacking and expand existing theories.

Findings

The results of the Delphi survey enable the main brand hijacking actions to be mapped, based on two motivational axes (utilitarian–idealistic and destructive–constructive) and on the various intentions that guide the hijackers. The results help re-define the key elements of brand hijacking, through the lens of non-collaborative brand co-creation.

Practical implications

Managerial implications are presented in terms of the corporate response to the two main effects of hijacking, namely, brand reputational damage and brand repositioning.

Originality/value

The paper helps to shed light on the main components of brand hijacking, thus gaining expert consensus in refining the existent conceptualization in relation to a rapidly changing brand management scenario because of the gradual loss by brand managers of their traditional control.

Abstract

Purpose

The purpose of this paper is to analyze the determinants of the performance of regional industrial technology development programs among the regional strategic industrial development program that the central government and Daegu metropolitan city jointly promoted between 2004 and 2012. Specifically, in this research, the authors are trying to identify the effects of R&D capabilities and technical development tasks on technological and managerial performance.

Design/methodology/approach

The dependent variables of this study are technical and economic performance. Technical performance, product and process innovation, economic performance, sales and export increases were measured using five-point Likert scales. The authors added the contribution of sales through technology development to economic performance. The independent variable is the company’s R&D capability, measured by the number of R&D staff compared to the average total number of employees from 2004 to 2012. The characteristics of the technology development tasks were measured by technical characteristics, market characteristics and collaborative research types. The technological characteristics were measured by seven factors, including technological change, technical difficulty, potential in commercialization, competition between domestic and foreign competitors, difficulty in introducing overseas technology and the technological gap. Market characteristics were largely divided into complexity, dynamics and competitiveness. The types of collaborative research were divided into whether or not there were collaborative research with the participation of large corporations. The control variables are firm size (number of employees) and firm age. Regression analysis was used to analyze the determinants of performance, and a difference analysis was conducted to determine the effect of collaborative research on performance.

Findings

The main determinants of the regional industrial technology development program performance are the characteristics of the technology development task rather than the internal R&D capability; moreover, the technical characteristics, complexity of the developed product market and participation of large corporations had significant effects on R&D capability. The R&D capacity of firms in internal R&D capacity had a significant effect only on the improvement of technology development ability. Therefore, R&D capacity, which is the main determinant of technology innovation, did not have a significant effect on the performance of short-term technology development tasks. Technological change, technological difficulty, competition between domestic and foreign competitors and the technological gap had positive effects on performance, excluding sales contributions. In addition, the complexity of the developed product market such as the diversification of demand, competitive product and sales distribution channels had positive influences on the performance of technology development programs, unlike dynamics and competitiveness. In this study, the authors cannot confirm the effect of collaborative research on the performance of the technology development programs, but they confirmed that collaborative research involving large corporations had a positive influence on performance.

Research limitations/implications

The results of the analysis of the determinants of regional industrial technology development programs suggest some implications in the future evaluation of these regional industrial technology development programs. It is necessary to review the application qualification and merit, advance review of the business plans and confirmation, an examination of the research results and performance of the applicants and a review of the technology and market situation of the project. For this, the authors suggest that the written review from the relevant technical experts be submitted to the evaluation committees. Also, when establishing regional industrial development programs, they should be evaluated thoroughly, including detailed information and contents about the technical and market characteristics of the local industry.

Originality/value

This research is one of the first to investigate the achievements of R&D support programs among regional industrial development programs in Korea. The results of this study can substantially contribute to the development and implementation of the R&D support policies of the central and local governments. Furthermore, the findings suggest guidelines for improving the performance of R&D support programs in the future. A theoretical model for enhancing the efficiency of government R&D support programs may be established, and an empirical analysis may be conducted to provide practical and academic implications for further research.

Abstract

Effective leadership in public schools includes, but is not limited to being able to communicate goals, set expectations, monitor instructional progress, coordinate the curriculum, and supervise and evaluate faculty (Snowden & Gorton, 2002). All of these leadership skills are driven by a need for leaders to build collaborative rapport and create a positive learning environment for both teachers and students. This study looked at the relationship between personality type as measured by the Keirsey Temperament Sorter (Keirsey & Bates, 1984) and leaders’ preferred leadership approaches as measured by the Instructional Leadership Beliefs Inventory (Glickman, 2002). Although this study found no significant correlations, the data provides insight to help determine how and to what extent personality type is related to a preferred leadership approach.

Abstract

Purpose

Rapid urbanisation and recent shock events have reiterated the need for resilient infrastructure, as seen in the pandemic. Yet, knowledge gaps in construction robotics and human–robot teams (HRTs) research limit maximising these emerging technologies’ potentials. This paper aims to review the state of the art of research in this area to identify future research directions in HRTs able to aid the resilience and responsiveness of the architecture, engineering and construction (AEC) sector.

Design/methodology/approach

A total of 71 peer-reviewed journal articles centred on robotics and HRTs were reviewed through a quantitative approach using scientometric techniques using Gephi and VOSviewer. Research focus deductions were made through bibliometric analysis and co-occurrence analysis of reviewed publications.

Findings

This study revealed sparse and small research output in this area, indicating immense research potential. Existing clusters signifying the need for further studies are on automation in construction, human–robot teaming, safety in robotics and robotic designs. Key publication outlets and construction robotics contribution towards the built environment’s resilience are discussed.

Practical implications

The identified gaps in the thematic areas illustrate priorities for future research focus. It raises awareness on human factors in collaborative robots and potential design needs for construction resilience.

Abstract

Purpose

This paper aims to explore the role and meaning of openness for the purpose of enhancing the understanding of collaborative innovation from an industrial network perspective.

Design/methodology/approach

The theoretical framework is based on the Industrial Network Approach, and the concepts of activity links, resource ties and actor bonds are used as a starting point for capturing the content and dynamics of the interaction. The empirical part consists of five case studies: two historical and three contemporary cases dealing with collaborative innovation projects. The cases are analyzed with regard to openness in business relationships and their connections in the network.

Findings

The main contribution is a conceptualization of openness in business relationships and relationship connections. The paper describes various forms and contents of openness – and closeness. It is postulated that the concept of openness can be used as an analytical tool for digging deeper into relationship and network-related issues of relevance to firms’ behavior in the context of collaborative innovation. Openness, as it is defined in this paper, is also put forward as an explanation of why (or why not) collaborative innovation projects become successful.

Originality/value

The conceptualization of openness differs from openness as it is commonly described in the open innovation literature. There, openness is the opposite of closeness, that is, a pattern where the innovation activities take place internally within the company. In this paper, openness, instead, has to do with how firms interact with other network actors in the context of collaborative innovation.
