Cognitive Mapping and Wayfinding in Childrenâs Home- School Itinerary
According to environmental and behavioural theories, individuals in their early years of cognitive development enter a world full of environmental stimuli that motivate them to perceive and learn. As a result of many perception processes, people convert and transfer perceived information into cognitive patterns that inform their understanding of the surroundings in which they operate and navigate around them. This paper aims to better understand the processes involved in navigating the home-school journey for children and delve into the likely impact of gender and age group of children on their perception of the environment and attempt to identify some of the factors that may affect their spatial behaviour. In doing so, there is the intention to develop a new approach to investigating wayfinding for school age children during their home-school journey. The approach consists of combining the analysis of cognitive maps drawn up by children, observation of their travel routines and space syntax tools. After contextualising the research through a literature review covering issues such as childrenâs spatial perception, navigation, wayfinding, and imageability, the paper describes the methods used to carry out the research, presents the results of the research and discusses them in order to shed some light on childrenâs wayfinding on the school journey
Green and Fast Extraction of Chitin from Waste Shrimp Shells: Characterization and Application in the Removal of Congo Red Dye
Due to their detrimental and carcinogenic effects, synthetic organic dyes pose significant environmental and health risks. Consequently, addressing the bioremediation of industrial wastewater containing these organic dyes has become an urgent environmental concern. The adsorption using low-cost and green materials is one of the best alternative techniques for the removal of dyes. This study aims to investigate the use of chitin to eliminate Congo red (CR), an anionic dye, from wastewater. The chitin was produced from shrimp shell in a quick and environmentally friendly manner by utilizing a co-solvent (glycerol/citric acid (GLC)). The resulting adsorbent was characterized through various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR spectroscopy. The effectiveness of CR removal with chitin was studied with respect to contact time, adsorbent dose, initial pH, equilibrium isotherms, and kinetic and thermodynamic parameters. It was observed that variations in the dye concentration and pH significantly influenced the removal of CR with chitin. Under optimal operating conditions (pH = 7, contact time = 130 min, temperature = 50 °C), the adsorption capacity reached 29.69 ± 0.2 mg/g. The experimental data revealed that CR adsorption onto a chitin adsorbent is better represented by a Langmuir isotherm
Pedestrian itinerary choice: between multi-sensory, affective and syntactic aspects of the street pattern in the historic quarter of Bejaia, Algeria
Consideration of the five senses and emotions is not well explored in the urban environment. Different fields deal with the influence of the physical environment on human experience. However, the role of the multi-sensory experience and affectivity in selecting the itinerary for pedestrian mobility is not yet well studied. Several methods have been proposed to evaluate the correlation between pedestrian movement and the environmental configuration, where the visual parameter is the main determinant. Given that other senses could be used to select any itinerary, since the urban environment is perceived at a multisensory level, the aim of the present study is to investigate the relationship between peopleâs multisensory experience and their navigation in an urban environment in terms of itinerary choice. This study is carried out on the streets linking the city centre to the seafront in Bejaia, Algeria. The investigation was based on qualitative and quantitative methods. The former consists of the organised walk with running commentary technique. The latter consisted of a syntactic analysis of the street pattern. The results show that people choose their itinerary not only on the visual aspect created by the spatial configuration, but also on several variables related to the affectivity and multi-sensory experiences of the urban environment. The findings will be discussed with regard to their usefulness for the design and development of urban publics spaces
Cities' Identity Through Architecture and Art
Intended to be a guide for academics, scholars, and interested leaders, this book was designed
to critically assess issues related to architectural identity, the city as a scene, the city as an
organism, the city as a subject, and the planning or rather approaching of one.
A pressing issue for many researchers in the field, the book discusses the negative repercussions
resulting from globalization. Studies have indicated that globalization, despite all the
positive effects, has resulted in a loss of identity within a city. As a city develops over time,
its identity is evolving as well and may even be lost due to rapid and constant changes it is
subjected to. Discussed as well are examples and tendencies in dealing with urban identities
as well as the transformation of cities and urban cultures mentioned in terms of form, identity,
and art.
This book is a combination of innovative research submitted to a conference on Citiesâ
Identity Through Architecture and Arts (CITAA) whereas scholars from all over the world
gather in one venue to discuss cultural, historical, and economic issues of the city. Thus, the
book offers a collective and global solution that is applicable on a universal level.
The research presented in this book was conducted by authors, or rather participants of
the conference from, three different continents of the world and organized by IEREK. It was
a distinct opportunity for them to share their thoughts with leading scholars and professionals
in the field of Architecture, Arts, and Planning.
The research and materials in this book are directed at those who are actively engaged in
the decision-making processes and to a heterogeneous audience who has an interest to critically
examine all the new literature available in the field.
A special word of thanks should be made to the editors of this book and to all the authors
and co-authors of the chapters who collectively provided the academic community with
unique and increasingly valuable literature

Adsorption of polycyclic aromatic hydrocarbons by natural, synthetic and modified clays
Polycyclic aromatic hydrocarbons (PAHs) are of major scientific concern owing to their widespread presence in environmental compartments and their potential toxicological effects on humans and biota. In this study, the adsorption capacity of natural (montmorillonite (Mt)), synthetic (Na-Mica-4), and modified (with octadecylamine and octadecyltrimethylamine (ODA-Mt, ODA-Mica-4, and ODTMA-Mt and ODTMA-Mica-4)) clays were assessed and compared for the removal of 16 PAHs. Materials were synthesized and characterized by X-Ray diffraction, Zeta potential, and Fourier-transform infrared spectroscopy. The results showed its correct preparation and the incorporation of PAHs in the structure of the clays after the adsorption tests. The proposed materials were effective PAH adsorbents, with adsorption percentages close to 100%, in particular those using Mt. Mt and Na-Mica-4 presented a better adsorption capacity than their organofunctionalized derivatives, indicating that the adsorption of PAHs may occur both in the surface part and in the interlayer. The proposed adsorbents take the advantage of being a low cost and highly effective. They can be an interesting alternative for wastewater treatment and soil remediation to prevent PAH contamination.Spanish Ministry of Economy, Industry and Competitiveness CTM2017-82778-
Exploiting ground effects for surface transport noise abatement
Growing demand on transportation, road and railway networks has increased the risk of annoyance from these sources and the need to optimise noise mitigation. The potential traffic noise reduction arising from use of acoustically-soft surfaces and artificial roughness (0.3 m high or less) is explored through laboratory experiments, outdoor measurements at short and medium ranges and predictions. Although the applicability of ground treatments depends on the space usable for the noise abatement and the receiver position, replacing acoustically hard ground by acoustically-soft ground without or with crops and introducing artificial roughness configurations could achieve noise reduction along surface transport corridors without breaking line of sight between source and receiver, thereby proving useful alternatives to noise barriers. A particularly successful roughness design has the form of a square lattice which is found to offer a similar insertion loss to regularly-spaced parallel wall arrays of the same height but twice the width. The lattice design has less dependence on azimuthal source-receiver angle than parallel wall configurations
Using natural means to reduce surface transport noise during propagation outdoors
This paper reviews ways of reducing surface transport noise by natural means. The noise abatement solutions of interest can be easily (visually) incorporated in the landscape or help with greening the (sub)urban environment. They include vegetated surfaces (applied to faces or tops of noise walls and on building façades and roofs ), caged piles of stones (gabions), vegetation belts (tree belts, shrub zones and hedges), earth berms and various ways of exploiting ground-surface-related effects. The ideas presented in this overview have been tested in the laboratory and/or numerically evaluated in order to assess or enhance the noise abatement they could provide. Some in-situ experiments are discussed as well. When well-designed, such natural devices have the potential to abate surface transport noise, possibly by complementing and sometimes improving common (non-green) noise reducing devices or measures. Their applicability strongly depends on the available space reserved for the noise abatement and the receiver position
Optimization of facade design based on the impact of interior obstructions to daylighting
Overcrowding in the perimeter zone is an inevitable issue in residential rooms with limited space. Obstructions, such as furniture and household items, may block the existing windows, and therefore affect interior daylight conditions. A facade design approach is needed that simultaneously takes into account daylighting and the volume of usable space for obstructions in the perimeter zone of such rooms. This study simulates daylight distributions in a typical small residential room with obstructions in front of windows. The simulation consists of two parts. First, the effects on horizontal illuminances caused by different positions and shapes of obstructions are examined under an overcast sky. Second, the maximum usable space volumes for obstructions of 51 optimized facade configurations are calculated in terms of four window-to-wall ratios (WWRs). The results of this study show that optimizing the forms of facade design can increase the usable interior space volume and meet the daylighting requirements of Chinese standards for small residential rooms. Additionally, by using the optimized facade forms, a facade with a WWR value of 50% provides the maximum usable space for obstructions. Based on the above results, this paper presents two matrices that can help architects in selecting the appropriate fenestration methods and confirming the size of usable space and allocation for residents
