Abstract
Purpose
Due to the limitations of conventional urban planning, it is essential to develop novel techniques of urban futruing. This paper aimed to use the scenario technique to create four plausible narratives of the future of Isfahan. Also, the authors described the problems of city foresight in the Global South.
Design/methodology/approach
This paper chronicles the Schwartzian steps taken to build explorative scenarios of Isfahan City in Iran in 2040. After using a STEEPV (Social, Technological, Environmental, Economic, Political, Value) analysis, the authors prioritized the collected variables by combining influence diagrams, the iceberg metaphor and an expert-based survey. Once the key uncertainties were derived, four scenarios were developed and discussed.
Findings
Through thematic analysis of the official visions of Isfahan’s future and the juxtaposition of these narratives with insight yielded in the scenario-development process, the paper concludes that the Northernness of the prevailing urban imaginaries, uncritical mimetic benchmarking, depoliticization of urban futures and the decorative reductionistic visions colonize urban futures in Isfahan/Iran. Critical/deconstructive city foresight and application of discomfort/ignorance criteria in the generation of scenarios can improve the rigor and quality of city foresight in the Global South.
Originality/value
The application of city foresight in the Global South has been limited. The paper is a step toward bridging this gap and providing some recommendations on how city foresight in the Global South might differ from its counterparts in the Global North.

Abstract
Purpose
The study's main objective is to evaluate the morphological developments in the characteristics of the spatial configurations of the residential layouts in Kerman, Iran, in examining the impact on the level of visual privacy through the spectrum of permeability and wayfinding in space syntax analysis.
Design/methodology/approach
In this paper, plan graph analysis is used to measure the syntactic properties of seven topological residential architecture plans in Kerman, Iran, built from the 1970s to 2010s. The methodology involves the development of mathematical measurements to signify permeability and simulation of visibility graph analysis (VGA) to indicate wayfinding.
Findings
The findings reveal the residential layouts of Iranian houses tend to be less integrated over decades of design development from the 1970s to 2010s. Reduction in spatial integration corresponds to increase segregation allowing for enhanced visual privacy. The study underpins that, even with the constraints in the scale of the house and reduction in the number of nodes, as evident in the design of the modern residential layout, the efficient level of visual privacy is still achievable with regards to the standards demanded by the local culture.
Originality/value
The study examines the development in residential spatial configuration and building scale on visual privacy through a proposed methodology based on the level of permeability and wayfinding measured as a combined effect using the space syntax analysis and visual accessibility.

Abstract
Purpose
The purpose of this paper is to design and implement a team of middle size soccer robots to conform RoboCup middle‐size league.
Design/methodology/approach
First, according to the rules of RoboCup, a middle size soccer robot was designed. The proposed autonomous soccer robot consists of the mechanical platform, motion control module, omni‐directional vision module, front vision module, image processing and recognition module, investigated target object positioning and real coordinate reconstruction, robot path planning, competition strategies, and obstacle avoidance. This soccer robot equips the laptop computer system and interface circuits to make decisions.
Findings
In fact, the omni‐directional vision sensor of the vision system deals with the image processing and positioning for obstacle avoidance and target tracking. The boundary‐following algorithm is applied to find the important features of the field. The sensor data fusion method is utilized in the control system parameters, self‐localization, and world modeling. A vision‐based self‐localization, and the conventional odometry systems are fused for robust self‐localization. The localization algorithm includes filtering, sharing, and integration of the data for different types of objects recognized in the environment.

The purpose of this paper is to investigate the hydromagnetic third-grade non-Newtonian fluid flow and heat transfer between two coaxial pipes with a variable radius ratio.
Abstract
Purpose
The purpose of this paper is to investigate the hydromagnetic third-grade non-Newtonian fluid flow and heat transfer between two coaxial pipes with a variable radius ratio.
Design/methodology/approach
To solve the approximate nonlinear and linear problems with variable coefficients, a trial function was applied. Methods include collocation, least square and Galerkin that can be applied for obtaining these coefficients.
Findings
It is revealed that an increase of the non-Newtonian parameter, Hartmann number, and radius ratio leads to an augmentation of the absolute value of the dimensionless velocity, temperature, velocity gradient, and temperature gradient of about 10-60%. Further, the augmentation of Bi1 reduces the absolute value of the dimensionless temperature profile and dimensionless temperature gradient about three to four times; hence, the dimensionless heat transfer rate reduces. However, the growth of Bi2 has a contrary impact. Besides, the increase of Pr and Ec leads to an increase in the dimensionless temperature profile and dimensionless temperature gradient; therefore, the dimensionless heat transfer rate increases.
Originality/value
The convection heat transfer on the walls of the pipes is considered, and the nonlinear coupled momentum and energy equations are solved using the least squared method and collocation methods, respectively.

Abstract
Purpose
This study aims to scrutinise the impact of fibre length and its composition on the tribological attributes of oil palm fibre (OPF) polymeric composite as an alternative brake friction material.
Design/methodology/approach
Fabrication of the sample was conducted by using a hot-compression method. The tribological test was carried out by deploying a ball-on-disk tribometer. Analysis of the data was then done by using the Taguchi approach as well as analysis of variance.
Findings
The results indicated that all design variables (fibre composition, length and treatment) are not statistically significant, as all p-values are greater than 0.05. Remarkably, irrespective of the fibre treatment, the wear rate and coefficient of friction (COF) distribution suggested that a smaller fibre length with a high fibre composition might enhance the composite’s tribological performance with COF of 0.4 and wear rate below than 1 × 10–9 mm3/Nm. The predominant wear mechanisms were identified as micro-cracks, fine grooves and fibre debonding.
Research limitations/implications
In this study, all-inclusive scrutiny needs to be carried out for further exploration.
Originality/value
The main contribution and novelty of this study are opening a new perspective on the formulation of new substances from bio-based material (i.e. OPF) that possess superior tribological characteristics for friction-based applications.

Abstract
Purpose
Drawing on the competing values framework, we look at the relationship of different organizational cultures (clan, hierarchy, adhocracy and market) with organizational performance. Furthermore, we examine the mediating role of knowledge sharing (attitude and behavior) in the organizational culture and organizational performance relationship.
Design/methodology/approach
We draw on survey data from 241 respondents working in the aerospace and aviation manufacturing and services firms in Pakistan (85), Turkey (65) and the United Arab Emirates (91). We employ structural equation modeling for data analysis.
Findings
Results suggest that knowledge sharing partially mediates the relationship between clan culture and organizational performance, and fully mediates the market culture and organizational performance relationship. Hierarchy culture is only positively related to organizational performance, while adhocracy culture shows no relationship with knowledge sharing, let alone organizational performance.
Originality/value
While knowledge sharing enhances organizational performance, there is limited knowledge with regard to the specific organizational culture(s) conducive to knowledge sharing and organizational performance. The study extends existing research on the topic and contributes by showing which cultures are more conducive to knowledge sharing and organizational performance and which are less.

Abstract
Purpose
This paper aims to examine the integration of lateral transshipment and road vulnerability into the humanitarian relief chain in light of affected area priority to address equitable distribution and assess the impact of various parameters on the total average inflated distance traveled per relief item.
Design/methodology/approach
After identifying comprehensive critical criteria and subcriteria, a hybrid multi-criteria decision-making framework was applied to obtain the demand points’ weight and ranking in a real-life earthquake scenario. Direct shipment and lateral transshipment models were then presented and compared. The developed mathematical models are formulated as mixed-integer programming models, considering facility location, inventory prepositioning, road vulnerability and quantity of lateral transshipment.
Findings
The study found that the use of prioritization criteria and subcriteria, in conjunction with lateral transshipment and road vulnerability, resulted in a more equitable distribution of relief items by reducing the total average inflated distance traveled per relief item.
Research limitations/implications
To the best of the authors’ knowledge, this study is one of the first research on equity in humanitarian response through prioritization of demand points. It also bridges the gap between two areas that are typically treated separately: multi-criteria decision-making and humanitarian logistics.
Practical implications
This is the first scholarly work in Shiraz focused on the equitable distribution system by prioritization of demand points and assigning relief items to them after the occurrence of a medium-scale earthquake scenario considering lateral transshipment in the upper echelon.
Originality/value
The paper clarifies how to prioritize demand points to promote equity in humanitarian logistics when the authors have faced multiple factors (i.e. location of relief distribution centers, inventory level, distance, lateral transshipment and road vulnerability) simultaneously.

Abstract
Purpose
The purpose of this study is to examine the proper structure for the integrated reporting of hi-tech knowledge-based organizations (KBOs); in particular, the authors evaluate the appropriateness of the concept and elements of integrated reporting for hi-tech KBOs.
Design/methodology/approach
The study uses an exploratory sequential mixed-method approach, including an initial qualitative case study, then an instrument development phase (Delphi), and finally, a quantitative survey.
Findings
The resulting analysis concluded that hi-tech KBOs have the potential to prepare a simplified, integrated report. The organization overview, governance, business model, strategies and resource allocation, performance, opportunities and risks are the content elements relevant to be included in the hi-tech KBOs annual report. However, the organization’s future outlook is not confirmed to be included. Due to liability and competitive concerns, organizations do not provide targets, forecasts, projections or even scenarios.
Research limitations/implications
Focus on a single country and a small sample of interviewees participated.
Practical implications
This paper concludes that the existing integrated reporting framework is useful for different types of organizations, but with some modifications. In addition, it analyzes how directors of Iranian hi-tech KBOs perceive and value content elements of integrated reporting.
Social implications
This paper suggests that the fulfillment of corporate transparency for Iranian hi-tech KBOs can be achieved by the policymaker’s support on integrated reporting.
Originality/value
Iran is swiftly moving toward a knowledge-based economy, and hi-tech KBOs will become the powerhouse of the economy. It is important to understand how managers of Iranian hi-tech KBOs perceive and value integrated reporting. The previous practical studies are not focused on Iranian firms and the impacts of integrated reporting on hi-tech KBOs and its implementation and effectiveness had not been studied before.
