Abstract
This research solicits the opinions of the residents of the Keçiören district of Ankara, Turkey, in order to learn their preferences about their local postmodern environment where the municipality forces all contractors and architects to adhere to strict planning laws requiring Turkish folk and Islamic architectural references. The Municipality of Keçiören, as an agent of civil power, manages the architectural and urban transformation of the area from a district formerly composed of squatter housing to one comprised of, in the words of Robert Venturi, “decorated sheds,” in an effort to create a different looking environment rich in nostalgia and excitement. In this research, a total of 7 different sets of apartment façades were analyzed, with each set comprising three examples each of minimum complexity (representing the former condition of the district), intermediate complexity (representing “high” architecture designed by an architect, which does not exist in the district) and maximum complexity (representing the present postmodern condition of the district). The main hypothesis of the study was that preference rates would be high for intermediately altered “high style” houses by showing the existence of a U-shaped relationship between preference and complexity. That is, façades representing an intermediate level of complexity would be favored over less complex and more complex façades. It was also assumed that there would be a difference in the ratings of different age groups. A questionnaire was carried out with 50 adults (aged 30-45) and 50 high school students (aged 18-20) of Keçiören, who were asked to rate a total of 21 photographs from 7 apartment complexes with the help of a five-point semantic differential scales under three headings: preference, complexity and impressiveness. The results proved the existence of a U-shaped relationship between preference and complexity. On the other hand, younger respondents, compared to older respondents, gave more favorable ratings to the physical qualities of the photographed buildings.

Abstract
Purpose
Previous studies have identified concerns and anxiety in individuals who are without their mobile phones, which is known as nomophobia, an acronym for “no mobile phone phobia.” However, there is currently limited evidence of qualitative research that explores nomophobia. The purpose of this study is to explore personal experiences and individual meanings associated with mobile phone use and nomophobia.
Design/methodology/approach
To address this gap, the present study employed a Heideggerian phenomenological approach to investigate the issue. Ten college students, who have medium to high nomophobia were selected as respondents. Semi-structured interviews were conducted to collect data, which were then transcribed verbatim and analyzed using reflexive thematic analysis.
Findings
A deep understanding of the psychological dynamics, experiences, meanings, perceptions and beliefs of individuals regarding smartphone use can only be explored through a qualitative approach that presents personal statements of individuals through in-depth semi-structured interviews. This study contributes to a deep understanding of the psychological dynamic of nomophobia.
Research limitations/implications
This study has limitations that must be carefully considered. First, the respondents came from a university with a sample size of 10 people, which may not fully represent the phenomenon of nomophobia among students due to differences in cultural and academic backgrounds. However, we addressed this limitation by selecting only students who scored moderate to high levels of nomophobia. Second, the researchers acknowledge that the sample used in the study may not be fully representative of the broader target population or a larger group, as previously mentioned. Therefore, generalizing the findings of this research must be done carefully, being cautious and thoughtful to avoid hasty conclusions.
Practical implications
In the functional context, it is recommended for individuals to be more mindful of their smartphone usage and strive to strike a balance between utilizing their device's capabilities for productive purposes and avoiding excessive dependency that may lead to distractions or information overload. This includes limiting excessive smartphone usage for entertainment purposes, restricting aimless and irrelevant Internet browsing and implementing effective time management when using smartphones. For smartphone users from the ontological context, the advice is to critically evaluate their digital presence and ensure that their online activities align with their true values and self-perception, promoting responsible and ethical smartphone use. Engaging in fasting or break sessions by completely turning off the smartphone at specific times and utilizing that time for activities such as reading books, writing and engaging in spiritual practices, or exercising is also advisable. In the anthropomorphic context, individuals are advised to reflect on the potential emotional dependence on their smartphones and consider establishing healthy boundaries to avoid excessive reliance on these devices to fulfill emotional needs. One practical recommendation is to engage in self-reflection, where individuals take some time to ponder their smartphone usage patterns and emotional attachment to the device. They should ask themselves why they feel the need to constantly check their phone and how it impacts their emotions and overall well-being.
Originality/value
This study contributes to a deep understanding of the psychological dynamics of nomophobia by exploring the experiences, meanings, perceptions, and beliefs of individuals regarding smartphone use.

Abstract
Purpose
This study aims to determine the effects of three different carrier system materials (laminated wooden beams, post-tensioned concrete beams and steel beams) used widely in interior spaces on the perceptual evaluations of respondents.
Design/methodology/approach
The large opening Olympic swimming pool space was chosen as the research environment. A total of 376 university graduates participated. After experiencing the 360-degree virtual images of the experimental spaces, a “spatial perception” questionnaire was applied to these respondents.
Findings
The spaces using the laminated wood beams in the carrier system were perceived as warmer, lighter, more attractive, more spacious, more informal, closer, more well-planned, freer, simpler, more peaceful, more exciting, and uncrowded compared to the spaces that used post-tensioned concrete beams and steel beams. The architect respondents made more negative perceptual evaluations for all the adjective pairs compared to the respondents in the other professional groups. Respondents who were males, and in the 26–35 years of age group, perceived more positively the physical environmental factors of the virtual swimming pools compared to females, and the 36 years of age or above age group.
Originality/value
The results set forth that the structural elements of buildings, such as ceilings, walls and furnishings, were not only systematic elements used in the formation of the structure, they were also important environmental factors in the perceptual evaluation of the space.

Abstract
Purpose
Over the past few decades, several base isolation systems have been developed to enhance the performance of structures under extreme earthquake shaking intensities. Recently, to achieve high energy dissipation capabilities, a new generation of multi-stage friction pendulum (FP) bearings known as the “Quintuple Friction Pendulum (QFP)” was introduced in the literature. With the help of its five effective pendula and nine operational regimes, this bearing's major benefits stem from its ability to accomplish complicated multi-stage adaptive behavior with smoothed loading and unloading when subjected to lateral forces.
Design/methodology/approach
Within the assessment context, five finite element models of reinforced concrete frames supported on QFP isolators with different properties will be developed in OpenSees. Thereafter, a set of 60 earthquakes will be analyzed using the nonlinear time history analysis approach, and the impact of each ground motion record's properties will be evaluated.
Findings
Overall, the study's findings have demonstrated that the characteristics of the isolator, combined with the type of earthquake being applied, have a substantial impact on the isolator's behavior.
Originality/value
Currently, no studies have examined the energy distribution of structural systems equipped with this type of isolation system while considering the influence of earthquake characteristics. Thus, this study is intended to extend the findings available in the literature by discussing and illustrating the distribution of strong ground motions input energy into highly nonlinear base-isolated systems that account for the bearing and superstructural materials' nonlinearity, geometric nonlinearity and leakage-prevented viscous damping nonlinearity. Besides, it investigates the influence of various earthquake characteristics on the energy dissipation of such buildings.

Abstract
Purpose
The present article encourages urban tourism researchers use pre-recorded (like YouTube, TikTok and security camera footage) and self-recorded video data in research. The author highlighted the benefits of doing so for urban tourism scholars, as well as ways in which these investigators can use the observational video analysis technique to produce convincing findings and advance their field.
Design/methodology/approach
To accomplish the purpose, the author reviewed 25 scholarly articles on the topic from several fields.
Findings
One benefit of observational video analysis research (OVAR), the author highlighted, was the ability of scholars in different locations to simultaneously observe interactions, the focus of the study, in their natural setting and discuss them. This practice is not possible with traditional ethnographic research. Also, one way the author mentioned researchers can accomplish rigor in their OVAR project is through multimodal transcription. With multimodal transcription, verbal and non-verbal happenings in videos are transliterated and later analyzed.
Research limitations/implications
It is hoped because of the present article, increased use of the technique in urban tourism research will be seen.
Originality/value
The present article is the first, to the best of the author’s knowledge, to detail how rigor can be accomplished in OVAR in urban tourism.

Abstract
Purpose
The purpose of this article covers the design and manufacture of porous materials that can be used in different engineering applications by additive manufacturing.
Design/methodology/approach
The most important design parameters of the porous materials are the cell structure and wall thickness. These two design criteria are difficult to control in porous materials produced by conventional production methods. In the study, two different wall thicknesses and four different pore diameters of the porous structure were determined as design parameters.
Findings
A compression test was applied to the produced samples. Also, the densities of the produced samples were compared. As a result of the study, changes in mechanical properties were observed according to the cell wall thickness and pore size.
Originality/value
The originality of the study is that, unlike traditional porous structure production, the pore structure and cell wall thicknesses can be produced in desired dimensions. In addition, a closed pore structure was tried to be produced in the study. Studies in the literature generally have a tube-type pore structure.

Abstract
Purpose
Using a mobile phone is increasingly becoming recognized as very dangerous while driving. With a smartphone, users feel connected and have access to information. The inability to access smartphone has become a phobia, causing anxiety and fear. The present study’s aims are as follows: first, quantify the association between nomophobia and road safety among motorists; second, determine a cut-off value for nomophobia that would identify poor road safety so that interventions can be designed accordingly.
Design/methodology/approach
Participants were surveyed online for nomophobia symptoms and a recent history of traffic contraventions. Nomophobia was measured using the nomophobia questionnaire (NMP-Q).
Findings
A total of 1731 participants responded to the survey; the mean age was 33 ± 12, and 43% were male. Overall, 483 (28%) [26–30%] participants received a recent traffic contravention. Participants with severe nomophobia showed a statistically significant increased risk for poor road safety odds ratios and a corresponding 95% CI of 4.64 [3.35-6.38] and 4.54 [3.28-6.29] in crude and adjusted models, respectively. Receiver operator characteristic (ROC)-based analyses revealed that NMP-Q scores of = 90 would be effective for identifying at risk drivers with sensitivity, specificity and accuracy of 61%, 75% and 72%, respectively.
Originality/value
Nomophobia symptoms are quite common among adults. Severe nomophobia is associated with poor road safety among motorists. Developing screening and intervention programs aimed at reducing nomophobia may improve road safety among motorists.

Abstract
Purpose
This study aims to test the relationship between ageing, professional status and well-being and the moderating role that job resources might have in this relationship.
Design/methodology/approach
The authors relied upon the literature on well-being and the job demands–resources (JD-R) model and employed the Copenhagen psychological questionnaire administered to patient care workers in three paediatric hospitals belonging to the same healthcare organization.
Findings
The findings, on the one hand, confirm a not-significant relationship between ageing, professional status and well-being; on the other hand, they indicate that job resources have a positive, significant and direct impact on well-being and a significant role in moderating the relationship between ageing, professional status and well-being.
Originality/value
The present paper has manifold academic and practical interesting implications as it contributes to the literature on the well-being of healthcare workers and provides implications to identify interventions for better human resource (HR) management in the healthcare context.
