Abstract
Purpose
Sustainable design is a new paradigm to localize sustainable development. The Union Internationale des Architectes (UIA) prepared guidelines for architectural projects to contribute to the Sustainable Development Goals (SDGs). Using the theory of change, the Department of Architecture at Menofia University set the 2023 graduation project to explore the possibility of adopting sustainable design principles and integrating SDGs into architectural education. The paper documents and evaluates the experiment to drive best practices and lessons learned.
Design/methodology/approach
The paper utilized a mixed design strategy utilizing qualitative and quantitative techniques. It gathered data from various sources, including a student questionnaire and unstructured interviews with external examiners. Data analysis included frequency distribution and sentiment, content and thematic analyses. Triangulation is applied, combining data, investigator and methodological triangulation to enhance the paper’s validity.
Findings
Integrating SDGs into the 2023 graduation project contributed to students’ understanding of sustainable urban development. Students demonstrated varying receptiveness to guidelines, focusing mainly on the SDGs (1-5, 7, 8, 10 and 11). Gender equality and economic empowerment struck a chord with the mostly female students, acknowledging that securing well-paying jobs is a way to escape the cycle of poverty. Challenges included limited resources and time constraints, a scarcity of Arabic reading materials and misunderstandings among students and staff, thus prompting collaborative efforts beyond standard studio hours. Despite challenges, the initiative contributes to sustainable urban development, providing valuable lessons learned and insights.
Originality/value
Integrating sustainable design principles into architectural education is doable but involves a complex process requiring careful preparation. The value lies in the tangible impact on sustainable urban development, emphasizing the importance of incorporating sustainable development concepts throughout the architectural curriculum. The authors advocate for increased awareness and education among stakeholders and suggest areas for future research by exploring a broader implementation and assessing the long-term effects on students’ mindsets and practices. Sustainable development is a means toward community prosperity, and the inquiry highlights the collective responsibility of scholars, practitioners and students in shaping a better future.

Abstract
Purpose
This study aims to deal the numerical simulation on buoyant convection and energy transport in an inclined cubic box with diverse locations of the heater and coolers.
Design/methodology/approach
The left/right walls are cooled partially whereas the other walls are kept adiabatic. In the left/right walls, three different locations of the cooler are examined, whereas heater moves in three locations in the middle of the enclosed box. The governing models are numerically solved using the finite-element method.
Findings
The simulations are done on several values of the Rayleigh number and cavity inclination angles and different locations of the heater and coolers. The results are presented in the form of streamlines, isosurfaces and Nusselt numbers for different values of parameter involved here. It is recognized that the inclination of the box and the locations of the coolers strongly influence the stream and energy transport inside the enclosed domain.
Research limitations/implications
The present investigation is conducted for steady, laminar, three-dimensional natural convective flow in a box for different locations of cooler and tilting angles of a cavity. The study might be useful to the design of solar collectors, room ventilation systems and electronic cooling systems.
Originality/value
This work examines the effects of different locations of cooler and tilting angles of a cavity on convective heat transfer in a 3D cavity. The study is useful for thermal engineering applications.

Abstract
Wireless sensor networks are expected to be an integral part of any pervasive computing environment. This implies an ever‐increasing need for efficient energy and resource management of both the sensor nodes, as well as the overall sensor network, in order to meet the expected quality of data and service requirements. There have been numerous studies that have looked at the routing of data in sensor networks with the sole intention of reducing communication power consumption. However, there has been comparatively little prior art in the area of multi‐criteria based routing that exploit both the semantics of queries and the state of sensor nodes to improve network service longevity. In this paper, we look at routing in sensor networks from this perspective and propose an adaptive multi‐criteria routing protocol. Our algorithm offers automated reconfiguration of the routing tree as demanded by variations in the network state to meet application service requirements. Our experimental results show that our approach consistently outperforms, in terms of Network Lifetime and Coverage, the leading semantic‐based routing algorithm which reconfigures the routing tree at fixed periods.

Abstract
In the previous chapter, I introduced trauma-informed care as an approach to organisational change and a shift in culture to recognise that many employees and people attending services have past trauma experiences. In this chapter, I recast servant leadership (SL) as a trauma-informed leadership model that naturally operationalises some of the principles discussed in the TIA literature. The first section of this chapter addresses the societal need for a more ethical and moral leadership approach, before briefly outlining the prevalence of trauma experienced by service users and employees. The next section provides an overview and definition of SL in a general sense, before articulating a trauma-informed model of SL and its characteristics. Finally, some of the outcomes associated with SL are discussed with a key focus on how this approach operationalises the principle of psychological safety, trust and empowerment found in trauma-informed approaches, as they relate to employees.

Abstract
Purpose
Practitioners, organisations and policy makers in health and social care settings are increasingly recognising the need for trauma-informed approaches in organisational settings, with morbidity and financial burdens a growing concern over the past few years. Servant leadership has a unique focus on emotional healing, service to others as the first priority, in addition to the growth, well-being and personal and professional development of key stakeholders. This paper aims to discuss Trauma Informed Servant Leadership (TISL).
Design/methodology/approach
A targeted review of the servant leadership and trauma-informed care literature was conducted. Relevant studies, including systematic review and meta-analysis, were sourced, with the resulting interpretation informing the conceptual model.
Findings
Although there are general guidelines regarding how to go about instituting trauma-informed approaches, with calls for organisational leadership to adapt the often cited six trauma-informed principles, to date there has not been a leadership approach elucidated which takes as its starting point and core feature to be trauma informed. At the same time, there is a paucity of research elucidating trauma outcomes for service users or employees in the literature when a trauma-informed approach is used. However, there is a large body of evidence indicating that servant leadership has many of the outcomes at the employee level that trauma-informed approaches are attempting to attain. Thus, the author builds on a previous conceptual paper in which a model of servant leadership and servant leadership supervision are proposed to mitigate against compassion fatigue and secondary trauma in the health and social care sector. The author extends that research to this paper by recasting servant leadership as a trauma-informed model of leadership that naturally operationalises trauma-informed principles.
Research limitations/implications
A lack of primary data limits the extent to which conclusions can be drawn on the effectiveness of this conceptual model. However, the model is based on robust research across the differential components used; therefore, it can act as a framework for future empirical research designs to be studies at the organisational level. Both the servant leadership and trauma-informed literatures have been extended with the addition of this model.
Practical implications
TISL can complement the trauma-informed approach and may also be viable as an alternative to trauma-informed approaches. This paper offers guidelines to practitioners and organisations in health and social care on how to operationalise important trauma-informed principles through leadership.
Social implications
This conceptual model may help reduce the burden of trauma and re-traumatisation encountered by practitioners and service users in health and social care settings, impacting on morbidity.
Originality/value
To the best of the author’s knowledge, this is a novel approach, the first of its kind.

Abstract
Purpose
An upsurge in health and environmental concerns over the use of synthetic color has made the development of color from cheap and easily available natural sources, namely, plants, animals, micro-organisms and algae as indispensable. This study aims to extract anthocyanins, an important natural plant pigments, from Sohiong (Prunus nepalensis). This study demonstrated that Sohiong have high anthocyanins content and antioxidant property, indicating an immense potential for the fruit producers and food processors.
Design/methodology/approach
Response surface methodology was used to optimize the conditions for extraction of anthocyanins from Sohiong using conventional solvent extraction.
Findings
The optimum conditions for extraction were found to be 36.75°C temperature, 60.32 per cent ethanol concentration and 2.39 per cent citric acid concentration with recovery of 45 per cent total extract yield, 858.84 mg C3G/100g DM anthocyanin content and 824.91 mg GAE/100g DM phenolic content with in-vitro antioxidant activity of 31.40 mmol AEAC/100g DM for FRAP and 84.66 per cent DPPH scavenging capacity (20mg/ml). The F-values and high values of adjusted determination coefficient for each response imply high level of significance of the fitted models.
Practical implications
Extracted color can be used in food and pharmaceutical industries.
Social implications
Pigment extracted is from a natural source and possesses high antioxidative activity and potential health benefits. With increasing demand for natural colors and other additives, there is a wide range of applications of the pigment as natural colorant in the food and pharmaceutical sector.
Originality/value
Selected plant source, i.e. Sohiong, was not used earlier by any researcher to extract anthocyanins for potential applications as food colorant.

Abstract
This article presents the results of a survey of 202 male Taiwanese consumers. In this study, consumer judgements of two technological products varying in their level of complexity made in highly, moderately, and newly industrialised countries were obtained in a multi‐attribute context. The results show that the country‐of‐origin image of moderately and newly industrialised countries was less negative for technologically simpler products (i.e. a television) than they were for technologically complex products (i.e. a computer). It appears that the negative image of moderately and newly industrialised countries can be attenuated by making Taiwanese consumers more familiar with products made in these countries and/or by providing them with other product‐related information such as brand name and warranty. Newly industrialised countries were perceived more negatively as countries of design than as countries of assembly, especially in the context of making technologically complex products. The image of foreign countries as producers of consumer goods was positively correlated with education. The more familiar consumers were with the products of a country, the more favourable was their evaluation of that country. Consumer involvement with purchasing a technologically complex product such as a computer was positively associated with the appreciation of products made in moderately industrialised countries. Managerial and research implications are derived from these results.

Abstract
Purpose
The purpose of this paper is to examine the impact of corporate governance strength on stock market liquidity in an emerging country, namely, Malaysia, by constructing a corporate governance score that captures both internal monitoring mechanisms (board of directors’ characteristics, audit committee’s characteristics and internal audit function) and external monitoring mechanism (audit quality).
Design/methodology/approach
The study uses a sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012. The ordinary least square regression and several estimation methods such as two-stage least squares using instrumental variables (IV-2SLS) and dynamic GMM are employed.
Findings
This study finds a significant positive association between corporate governance effectiveness and stock market liquidity. The finding is robust to alternative liquidity measurements, to alternative estimation methods, and to endogeneity bias.
Research limitations/implications
This result implies that the firms with effective monitoring mechanisms mitigate information asymmetry which leads to less adverse selection problems among traders.
Practical implications
This study provides implications for regulators to help design regulations that enhance stock market liquidity. This study could also help investors and traders to formulate their trading decisions, and enables firms to know the importance of strengthening the corporate governance monitoring mechanisms.
Originality/value
This study constructs a corporate governance effectiveness measure by combining both internal and external monitoring mechanisms. These mechanisms have not been constructed together in one score in the corporate governance literature and the impact of internal audit function, as an internal monitoring mechanism on liquidity, has yet to be examined.
