This study aims to explore the relationship between contemporary cities and traditional urban forms. The central focus lies in identifying the key factors that facilitate the harmonious coexistence of these contrasting sides of the city.

This study takes Iranian bazaars as exemplars of traditional urban forms. To assess their current status, a comprehensive examination of their general evolution is conducted, tracing the transition of these urban complexes up to the present day. Subsequently, morphological analysis and exploration of spatial arrangements across numerous cases are employed to unveil the factors contributing to their disappearance or adaptation within the framework of Iran’s contemporary urban era.

The evolution process of the Iranian bazaar shows that the encounter between traditional bazaars and modernity occurred swiftly and blindly, resulting in adverse effects on traditional urban forms, notably bazaars. In recent years, contemporary urban planning has undertaken corrective measures, adopting a more nuanced approach. This shift significantly strides in restoring the symbiotic relationship between cities and their traditional bazaars. Morphologically, certain bazaars have preserved their vitality in contemporary cities through their natural development patterns, adept integration with new urban textures and the implementation of ingenious adaptive strategies.

This study employs a comprehensive and equitable approach to examining a distinct category of traditional urban forms. It initiates the inquiry by meticulously considering historical continuity in conjunction with detailed contemporary circumstances, subsequently scrutinising their losses, damages and developmental aspects. An extensive collection of cases is assembled and subjected to a consistent analytical framework for comparative evaluation to obtain the most accurate result. Consequently, the outcomes of this research may help the present urban planners engaged in projects concerning the restoration, preservation, revitalisation and development of traditional urban forms.

This study aimed to explore the institutional theory as a lens for investigating how construction firms adapt to supply chain disruptions. Specifically, the paper evaluates the interactions and interdependencies amongst various organizations, participants and institutions in the construction industry as a basis for a holistic, adaptive response strategy for managing supply chain disruptions.

Following the tenets of relativist philosophy and qualitative research methodology, this study explores the lived experiences of senior-level managers across major construction firms in New Zealand through in-depth semi-structured interviews, as a basis for understanding how their respective organizations adapt to supply chain disruptions.

The research findings suggest that aside from the formal rules that guide the conduct of construction firms as they adapt to supply chain disruptions, informal interactions that exist amongst various organizations and players in the construction industry could also enhance the development of innovative and practical response strategies to supply chain disruptions.

This study makes original empirical contributions to the supply chain management literature by providing insights into how construction firms demonstrate normative, coercive and mimetic isomorphic tendencies amidst the complexity of supply chain disruptions. Insights from this study could enhance the adaptive response of construction firms to supply chain disruptions while also improving the overall resilience of the built environment.

The widespread adoption of online purchasing has prompted increasing concerns about product safety, and regulators are beginning to hold e-commerce sites accountable for dangerous product defects. For online consumers, understanding the many inherent safety risks among the extensive array of products they browse is a formidable task. The authors attempt to address this problem via a client-side software artifact that warns shoppers about potential product safety hazards at the point of sale.

In this study, the authors built four candidate designs and assessed their effectiveness by means of a large randomized controlled experiment (n = 466). The authors define effectiveness as significant changes in dependent variables associated with health behaviors and technology adoption.

The authors find that all of the designs score high on adoption likelihood, that designs incorporating highlighting and scoring are better at increasing safety knowledge and that simpler designs are better at enhancing safety awareness.

These findings will inform the design of safety information dissemination systems and open new areas of safety awareness enhancement research. More generally, the authors introduce a novel method of testing text visualization variations and their impact on behavioral decisions.

This case study is based on primary data collected through interviews with the company’s founder and CEO. It also includes secondary data collected through the Glassdoor job search and career community site. The names of the company and the employees have been disguised. However, the figures included accurately represent the primary data and the quotes are directly from the company representative.

When it was founded in 2009, employees were excited about the prospect of working at Wombat alongside its founder and CEO Dan Wallace. They had looked forward to making a difference in the lives of college students with the company’s higher ed-focused digital communication platform. But by 2022, Wallace could not ignore the significant change in these employees’ attitudes. Anonymous feedback pointed to employees’ commitment to Wombat having wavered, and employees’ reception of post-COVID organizational changes had become concerningly critical. Though he knew enough to be concerned, Wallace felt unsure of how to move forward based on the anonymous feedback alone. He was left wondering: how should Wombat communicate with employees to boost their attitudes and strengthen their commitment while making the hard decisions that best serve the company?

This case study is appropriate for upper-level undergraduate and graduate students in organizational communication courses. It can constitute the employee communication module in a class that surveys strategic managerial communication, or it could be used as one of many examples in a course specifically focused on the internal communication component of the discipline. Students will need an understanding of communication theory, specifically interpretive organizational communication theory, to grasp the complexities of the case. While the focus company is in the educational technology industry, the themes presented are faced by companies of all sizes in all sectors.

The purpose of this study is to scrutinize the connection between creativity and innovation in the context of public healthcare. This is achieved by applying the theoretical concept of employee-driven innovation (EDI) to explore employees’ perceptions of their creative engagement in innovation processes, as well as to capture the managerial implications of setting up such processes in the sector.

A critical discourse analysis (CDA) is applied as a methodological lens to capture the interaction between the macro-level production and meso-level distribution of innovation discourse (top-down), and the micro-level perception of, and response to, the same (bottom-up). This study is based on a qualitative approach and is set in the public healthcare system of the Autonomous Province of Trento, Northeast Italy. In total, 26 semi-structured interviews were conducted with 22 healthcare professionals. For triangulation purposes, observation and document analysis were also performed.

The findings of this study reveal that tensions are present between the macro-level discourses and the meso-level strategies around innovation, and the micro-level perceptions of employees’ creative engagement in innovation processes. Healthcare professionals’ creative efforts are not easily recognized and supported by top management, which in turn does not receive a framework of reference in policies acknowledging the importance of human skills and creativity in innovation processes.

That this is a single case study implies a limitation on the generalizability of its results, but the results may nevertheless be transferable to similar empirical contexts. Therefore, a multiple case study design would be preferable in future studies in order to study EDI strategies and policies across various types of organizations in the public sector. Moreover, apart from CDA, other theoretical and methodological lenses can be applied to investigate the interaction between top-down organizing and bottom-up responses to innovation.

This study contributes to the EDI literature by providing a more integrative understanding of EDI in the public sector, demonstrating the importance of scrutinizing the interactions between employees and top-level management.

Critical infrastructures are susceptible to unexpected disruptive events that affect their functional performance. Public–private partnership (PPP) offers opportunities for stakeholders to build resilience by proactively coordinating and positioning the capabilities of the stakeholders. Partnerships are mostly riddled with risks that affect the performance and goal attainment of the partnerships. The purpose of this study was to develop a risk assessment model for PPP in critical infrastructure resilience (CIR) using fuzzy synthetic evaluation.

This study used a quantitative approach to analyse survey responses from respondents. Mean score ranking, Kendall’s coefficient of concordance and fuzzy synthetic evaluation were used to analyse the responses from respondents.

This study identified seven risk categories; Political, Financial, Ethical, Bureaucracies and red tapes, Legal, Coordination and Institutional as the critical risk categories that may frustrate the partners in a PPP arrangement from performing their responsibilities. A risk assessment model was also developed in the form of a risk index equation to ascertain the risk level of using a PPP to build critical infrastructure resilience in Ghana. It was found that the risk level in using PPP to build critical infrastructure resilience is high.

The outcome of this study can be used as an informative and guiding tool to streamline any future PPP arrangement or even amend current PPP arrangements in critical infrastructure resilience.

The study has drawn attention to the risks in using PPP to build critical infrastructure resilience within the Ghanaian context. It has also established a risk index to assess the risk level of using PPP to build critical infrastructure resilience. This risk index can be used to ascertain the risk level in different countries. In addition, no research has been conducted to empirically test the risks in using PPP to build critical infrastructure resilience thus making this study a novel contribution to the critical infrastructure resilience research domain.

This study aims to examine the challenges in the implementation of energy management systems in residential buildings to lower the running cost and achieve a better energy-efficient building.

This study adopted a mixed research method. Quantitative data was gathered by issuing a research questionnaire to 20 Delphi experts, while qualitative data was acquired through a Systematic Literature Review. Data received was analyzed using the descriptive analysis method.

The findings revealed that the main barriers to incorporating energy management systems (EMSs) in residential buildings consist of a lack of awareness of energy management systems, lack of management commitment to energy management, lack of knowledge about energy management systems, lack of funds for energy management systems, resistance to energy management technology by the property owners and property managers, distrust and resistance to energy management technology by the property owners, high initial cost of energy management technologies, shortage of technicians for energy management technologies, the nonexistence of local manufacturers of energy management equipment, lack of incentives for efficient energy management and high repair costs of energy management technologies.

The specific focus on residential buildings may limit the applicability of findings to commercial or industrial sectors. Further research is warranted to accommodate other energy-consuming sectors.

People’s perceptions, either wrong or correct, affect their ability to make an informed decision to adopt energy management systems, denying them the opportunity to reap the associated benefits. Therefore, there is an urgent need for the residential industry stakeholders and the government to increase educational opportunities for property owners, managers and property tenants on the importance of energy management systems.

This research presents the potential obstacles and problematic areas that residents may encounter while using these energy management systems. Consequently, they will be able to make a well-informed choice when installing energy management systems. Moreover, the research elucidates the identification of novel perspectives and also unexamined obstacles that impede the widespread use of energy management systems in residential buildings.

Given that Indian languages in general are under-represented on the internet and that languages of minority linguistic groups find very little space on digital platforms, it is imperative for institutions such as libraries to cater to smaller communities and their educational needs while also reaching out to them in their own languages. This study aims to deliberate on strategies for enlisting community support for gathering diverse learning resources in different languages and for enlisting participation in activities such as crowdsourcing in initiatives such as annotations and transliteration.

This paper calls for interventions that imagine and create infrastructure for the flourishing of smaller libraries that can draw from and feed into large-scale national and international libraries. Offering a conceptual framework to rethink the country’s approach toward minor languages, it first offers an overview of policies and initiatives relevant to the concerns of minor languages in digital libraries in India. Based on the policy analysis, it then goes on to suggest starting points for policy designers and custodians of libraries to help them work toward better representation of languages in their resources.

The existing frameworks analyzed here for the greater or representation of minor Indian languages reveal a culture of silence toward the issue of language. With some advocacy, these frameworks can be mined to craft different ways that are critical not just for enriching libraries but also for preservation of cultural heritage of the communities concerned, thus adding a larger social dimension to the question of access.

While a lot of socio-political discourse on minority languages in India exists, this study pushes for their bearing on digital libraries, educational frameworks and cultural heritage.

Transient response of continuous composite material (CCM) fin made of high thermally conductive composite material is presented. The continuously varying effective properties of composite material such as thermal conductivity, heat capacity and density have been modelled using the Mori-Tanaka homogenization theory and rule of mixture. Additionally, temperature dependency of thermal conductivity, heat generation (composite materials) and convection coefficient (fluid properties) have also been incorporated. Different base boundary conditions are addressed such as oscillating heat flow, oscillating temperature, step-changing heat flow and step-changing temperature. At the other boundary, the fin is assumed to have a convective tip.

Lattice Boltzmann method is implemented using an in-house source code for obtaining the numerical solution of typical non-linear heat balance equation of the aforementioned problem under various transient base boundary conditions.

The effects of various thermal parameters such as material diffusivity ratio and conductivity ratio, area ratio and Biot number on transient response of fin and temperature distribution of fins are studied and interpreted. The heat transfer rate and time for attainment of steady state temperature of metal matrix composite (MMC) fin are found to be proportionally dependent on their diffusivity ratio. Additionally for higher values of area ratio and biot number, MMC fins are reported to dissipate the heat more efficiently in comparision to homogeneous fins in terms of time required to attain the steady state and surface temperature.

Response of transient fin associated with advanced class of material can facilitates the practicing engineers for designing high-performance and/or miniaturized thermal management devices as used in electronic packaging industries.

Studies of composite fin consisting of laminating second layer of material over the first layer have been reported previously, however transient response of CCM fin fabricated by continuously varying the volume fraction of two materials along the fin length has not been reported till date. Such material finds its application in thermal management and electronic packaging industries. Results are plotted in form of a graph for different application-wise material combinations that have not been reported earlier, and it can be treated as design data.
