Properly planned road illumination systems are collectively a public wealth and the commissioning of such systems may require extensive planning, simulation and testing. The purpose of this simulative work is to offer a simple approach to facilitate luminance-based road lighting calculations that can be easier to comprehend and apply to practical designing problems when compared to complex multi-objective algorithms and other convoluted simulative techniques.

Road illumination systems were photometrically simulated with a created model in a validated software platform for specified system design configurations involving high-pressure sodium (HPS) and light-emitting diode (LED) luminaires. Multiple regression analyses were conducted with the simulatively obtained data set to propound a linear model of estimating average luminance, overall uniformity of luminance and energy efficiency of lighting installations, and the simulatively obtained data set was used to explore luminaire power–road surface average luminance characteristics for common geometric design configurations involving HPS and LED luminaires, and four categories of road surfaces.

The six linear equations of the propounded linear model were found to be well-fitted with their corresponding observation sets. Moreover, it was found that the luminaire power–road surface average luminance characteristics were well-fitted with linear trendlines and the increment in road surface average luminance level per watt increment of luminaire power was marginally higher for LEDs.

This neoteric approach of estimating road surface luminance parameters and energy efficiency of lighting installations, and the compendia of luminaire power–road surface average luminance characteristics offer new insights that can prove to be very useful for practical purposes.

There is an ongoing discussion on tools that can lead to sustainable tourism, as well as attempts to implement them. In the selection of tools, the attitudes of residents – local stakeholders and their degree of acceptance of such tools should be analysed and taken into account. Some cause conflicts, and hence, the purpose of this study is the comparative analysis of three cities (Prague, Krakow and Braga).

Analysis of the basic types of conflicts was conducted using the division proposed by Moore. The research was conducted among residents – experts representing the tourism sector. Based on the literature review, three hypotheses were formulated. Statistical tests were used to analyse the results.

The results showed a strong impact of the conflict of information and the interests of those dependent on the degree of development of the city’s tourist function. It was established that in the process of achieving sustainable tourism, to minimize conflicts, the following are necessary: paying attention to communication and the involvement of local communities, creating attractions that benefit both residents and visitors, measuring and monitoring tourist traffic, supporting initiatives for new tourist offers and initiating discussions on development problems, and setting common goals for all residents.

The research was conducted during the pandemic and is based on the opinions of experts indicated by the city authorities. While the attitudes of the inhabitants towards the development of tourism were recognized in earlier studies, the awareness of tourists and their readiness to accept limitations related to respecting the needs of the inhabitants were not examined. This aspect may be an interesting direction for further research. A limitation of this research is the small scope of the study, caused both by the restrictions in force during the research period (related to the COVID-19 pandemic) and also by the inability to conduct in-depth interviews with experts. It should also be noted that among the experts participating in the research were tourist entrepreneurs directly interested in rebuilding tourism after the pandemic. Due to this, their opinions may have been biased, but there is no way to prove or disprove this. However, the answers gathered were considered collectively; therefore, the opinions obtained were considered to be objective. Attempts to balance tourism so far have focused mainly on limiting the access of tourists to attractions and tourist areas and introducing (or increasing) admission fees. It is still too early to assess the effectiveness of such tools, hence the lack of scientific analyses of implemented tourism policies.

The role and tasks of institutions managing tourism in cities will probably also change, in particular, so-called destination management organizations. The current declarations indicate the need to respect inhabitants and take measures to limit conflicts arising in the context of the development of the tourist function. However, there is no empirical evidence of the positive results achieved.

The results will allow the implementation of tourism balancing tools that are accepted by the local community.

The selection of the historical cities and the posing of a research problem based on the same tool allowed for comparative inference. The results can help shape tourism management in cities and the choice of tools for their sustainable development.

关于实现可持续旅游的工具以及运用这些工具的尝试始终是学界热议的话题。 在选择工具时, 应当分析和考虑居民和当地利益相关者的态度以及他们对工具的接受程度, 因为有些会引起冲突。基于此, 本文的目的是对三个城市（布拉格、克拉科夫、布拉加）的居民-当地利益相关者冲突进行比较分析。

本文采用摩尔提出的划分方法对冲突的基本类型进行了分析。 该研究是在居民——代表旅游部门的专家中进行的。文章基于文献综述提出了三个假设, 并 使用统计测试来分析结果。

结果表明, 信息冲突和利益冲突的强烈影响取决于城市旅游功能的发展程度。在实现可持续旅游的过程中, 为了尽量减少冲突, 有必要采取以下措施：注重当地社区的参与和沟通, 创造有利于居民和游客双方的景点, 测量和监测旅游流量, 支持旅游产品创新并发起针对发展问题的讨论, 同时为所有居民设定共同目标。

本文选择历史名城作为案例地, 加之基于同一工具提出的研究问题, 使得本研究具备用于比较推断的条件。 研究结果有助于塑造城市的旅游管理以及引导可持续发展工具的选择。

Hay un debate en curso sobre las herramientas que pueden conducir al turismo sostenible, así como los intentos de implementarlas. En la selección de herramientas, se deben analizar y tener en cuenta las actitudes de los residentes – agentes interesados locales y su grado de aceptación de dichas herramientas. Algunas provocan conflictos, de ahí que el objetivo de este artículo sea el análisis comparativo de tres ciudades (Praga, Cracovia, Braga).

El análisis de los tipos básicos de conflictos se realizó utilizando la división propuesta por Moore. La investigación se llevó a cabo entre residentes, expertos que representan el sector turístico. A partir de la revisión de la literatura se formularon tres hipótesis. Se utilizaron pruebas estadísticas para analizar los resultados.

Los resultados mostraron un fuerte impacto del conflicto de información y los intereses de quienes dependen del grado de desarrollo de la función turística de la ciudad. Se estableció que en el proceso de lograr un turismo sostenible, para minimizar los conflictos es necesario: prestar atención a la comunicación y a la implicación de las comunidades locales, crear atractivos que beneficien tanto a los residentes como a los visitantes, medir y monitorear el tráfico turístico, apoyar iniciativas de nuevas ofertas turísticas e iniciar debates sobre los problemas de desarrollo, y establecer objetivos comunes para todos los residentes.

La selección de las ciudades históricas y el planteamiento de un problema de investigación basado en la misma herramienta permitieron realizar una inferencia comparativa. Los resultados pueden ayudar a configurar la gestión del turismo en las ciudades y la elección de herramientas para su desarrollo sostenible.

Sustainable development (SD) is vital in alleviating poverty, hunger and disease (PHD). The purpose of this study is to present a guiding framework with pathways targeting the sustainability challenges concerning PHD based on urban planning and design literature.

A narrative review and content analysis of 27 articles published by 11 journals indexed in Scopus were conducted using bibliometrics analysis.

The study’s findings discuss contemporary normative planning and design ideas and their ability to alleviate PHD. Considering these findings, the authors recommend that urban planning and design implementation processes carefully pursue the United Nations Sustainable Development Goals (SDGs) and Vision 2030 by tracking qualitative metrics that consider social, cultural and spiritual well-being.

The contribution is to propose a conceptual framework for alleviating hunger, poverty and disease through Vision 2030. Practitioners and policymakers can use this framework to assess the impact of their actions. Hunger, poverty and disease research could be guided by this framework to identify and prioritize best practices in cities of the Global South.

This paper aims to analyse residents’ perceptions of tourism growth in Porto prior to the COVID-19 pandemic, aiming to determine the most appropriate strategies to mitigate negative tourism impacts. Studies on resident perceptions of tourism impacts are still scarce, particularly the ones addressing the topic in the context of Portuguese urban tourism areas.

Data was collected through an online survey, focusing on three categories of impacts: (i) economic, (ii) sociocultural (iii) and spatial-environmental, and the respective mitigation strategies, analysed from the perspective of Porto’s residents. Descriptive and bivariate statistics – T-test and Eta correlation – were used to analyse the collected data.

Respondents who live in the city centre experience specific tourism impacts more negatively, when compared to those living outside the inner-city area. Furthermore, no strong correlation is found between the said impacts and the respective mitigation strategies. However, creating awareness among tourists about acceptable behaviour in shared spaces is the strategy that stands out, as it has a medium correlation with all three impact categories. Most impact-strategy associations are weak, meaning that the defined strategies are not the most case-appropriate, which is something that policymakers should address.

To the best of the author’s/authors’ knowledge, this is the first study to adopt this approach in tackling the negative impacts of rapid tourism growth in Porto.

No country is free from financial crime issues. Therefore, this paper aims to discover how to control financial crime from the perspective of national culture.

This study conducted a bibliometric approach and systematic literature review analysis of 47 publications in the Scopus database.

Bibliometric and content analyses show that national culture is more often associated with tax evasion, money laundering and corruption. The role of national culture is less investigated currently in the schemes of financial statement crime, workplace fraud and cybercrime. Overall, the study concludes financial crime can be prevented by developing a culture that supports anti-fraud measures. These include individualized country profiles, feminism, low power distance, tolerance for uncertainty, short-term orientation and restraint.

This research provides clear knowledge of the role of the six dimensions of national culture in fighting financial crime. Finally, this study is also valuable for decision-making in designing more effective financial crime prevention programs.

Over the years, the significance of retrofitting has gained much attention with the unveiling of its different applications, such as energy retrofit and deep retrofit, to enhance the climate-resilience of buildings. However, no single study comprehensively assesses the climate-resilience of retrofitting. The purpose of this study is to address this gap via a systematic literature review.

Quality journal studies were selected using the PRISMA method and analysed manually and using scientometrics. Three dimensions of climate-resilience, such as robustness, withstanding and recovery, were used to evaluate the contribution of retrofit measures for achieving climate-resilient houses across four climate zones: tropical, arid, temperate and cold.

Most passive measures can enhance the robustness of residential buildings but cannot verify for withstanding against immediate shocks and timely recovery. However, some passive measures, such as night-time ventilation, show excellent performance over all four climate zones. Active measures such as heating, ventilation and air conditioning and mechanical ventilation with heat recovery, can ensure climate-resilience in all three dimensions in the short-term but contribute to greenhouse gas emissions, further exacerbating the long-term climate. Integrating renewable energy sources can defeat this issue. Thus, all three retrofit strategies should appropriately be adopted together to achieve climate-resilient houses.

Since the research is limited to secondary data, retrofit measures recommended in this research should be further investigated before application.

This review contributes to the knowledge domain of retrofitting by assessing the contribution of different retrofit measures to climate-resilience.

Night lighting reflects the prosperous development of economic and the increasingly rich and colorful cultural life. Currently, various technical standards, protocols and management specifications have been developed to build a safe, comfortable and economical lighting environment. However, prevailing evaluation systems focus on objective indexes of illumination and have ignored environmental characteristics and subjective feelings and lacked consideration of regional culture, economic benefit, management and maintenance. In this context, a lighting evaluation system combining subjective and objective is proposed for the first time in this study to explore approaches to guide the development of a healthy and comfortable urban night-time environment.

Existing research and relevant lighting standards are analyzed and an evaluation model with a logical hierarchy is constructed by combining with the evaluation theory that is set based on people and the environment. The index weights were scientifically determined on the basis of the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method. The rationality and validity of the proposed evaluation system is verified in accordance with field projects and case studies.

Taking into account traditional and cultural factors, the evaluation model established has an acceptable accuracy. Evaluation based on subjective-objective combination can provide a scientific basis for the management and optimization of night lighting.

The proposed evaluation system can serve as a guiding reference for other areas of cultural identity and esthetic perspective.

A main challenge in studying China is that different views clash. A more serious challenge is that studies that are critical of or dissent from the Chinese government policies are labeled “anti-China” by the Chinese authorities, affecting the free academic exchange of ideas on China. This article discusses this issue and proposes a long-term solution.

This is a perspective study and uses the qualitative approach to develop the authors’ arguments.

The authors argue that the contention in China-related studies is derived primarily from the different perspectives that scholars use. This study identifies two main perspectives: the China-centric view and the rest of the world’s view. The combination of the clash of perspectives and the interference of the Chinese state hinders the development of our knowledge regarding China. Using Rawls’ theory of justice and the veil of ignorance, the authors propose to build common ground for the China study community based on academic freedom, equality and the rule of law. This study further shows that building the common ground is feasible.

The authors’ proposed common ground will help create a free environment for meaningful exchange between different perspectives and reduce the risks in China studies.

The authors’ angle to examine the contentiousness and riskiness of China studies is new. It is the first time that different perspectives on China studies are delineated and compared, the costs of the contentiousness and riskiness are assessed, and the long-term consequences of different paths are examined.

Green roofs are strategies for the ecological intensification of cities and a measure of meeting some of the sustainable development goals (SDGs). They have widely been adopted as an adaptation strategy against an urban heat island (UHI). However, they are conventionally soil-based making it difficult and expensive to adopt as a strategy for greening existing buildings (GEB). This paper, therefore, develops a novel green roof system using climbers for thermal-radiative performance. The paper explores the vitality of climbing species as a nature-based strategy for GEB, and for the ecological improvement of the predominantly used cool roofs in sub-Saharan Africa (SSA).

Simulation for the same building Kejetia Central Market (KCM) Redevelopment; the existing aluminium roof (AL), soil-based extensive green roof (GR1) and the proposed green roof using climbing plants (GR2) were performed using ENVI-met. The AL and GR1 were developed as reference models to evaluate and compare thermal-radiative performance of the conceptual model (GR2). The long wave radiation emission (Q_lw), mean radiant temperature (MRT) and outdoor air temperature (T_a) of all three roofing systems were simulated under clear sky conditions to assess the performance and plant vitality considering water access, leaf temperature (T_f) and latent heat flux (LE₀) of GR1 and GR2.

There was no short wave radiation (Q_sw) absorption at the GR2 substrate since the climbers have no underlying soil mass, recording daily mean average Q_lw emission of 435.17 Wm⁻². The soil of GR1, however, absorbed Q_sw of 390.11 Wm⁻² and a Q_lw emission of 16.20 wm⁻² higher than the GR2. The AL recorded the lowest Q_lw value of 75.43 Wm⁻². Also, the stomatal resistance (r_s) was higher in GR1 while GR2 recorded a higher average mean transpiration flux of 0.03 g/sm³. This indicates a higher chance of survival of the climbers. The T_a of GR2 recording 0.45°C lower than the GR1 could be a good UHI adaptation strategy.

No previous research on climbers for green roof systems was found for comparison, so the KCM project provided a unique confluence of dynamic events including the opportunity for block-scale impact assessment of the proposed GEB strategy. Notwithstanding, the single case study allowed a focussed exploration of the novel theory of redefining green roof systems with climbers. Moreover, the simulation was computationally expensive, and engaging multiple case studies were found to be overly exhaustive to arrive at the same meaningful conclusion. As a novelty, therefore, this research provides an alternative theory to the soil-based green roof phenomenon.

The thermal-radiative performance of green roofs could be improved with the use of climbers. The reduction of the intensity of UHI would lead to improved thermal comfort and building energy savings. Also, very little dependence on the volume of soil would require little structural load consideration thereby leading not only to cheaper green roof construction but their higher demand, adoption and implementation in SSA and other low-income economies of the global south.

The reduction of the consumption of topsoil and water for irrigation could avoid the negative environmental impacts of land degradation and pollution which have a deleterious impact on human health. This fulfils SDG 12 which seeks to ensure responsible consumption of products. This requires the need to advance the research for improvement and training of local built environment practitioners with new skills for installation to ensure social inclusiveness in the combat against the intractable forces of negative climate impacts.

Climbers are mostly known for green walls, but their innovative use for green roof systems has not been attempted and adopted; it could present a cost-effective strategy for the GEB. The proposed green roof system with climbers apart from becoming a successful strategy for UHI adaptation was also able to record an estimated 568% savings on topsoil consumption with an impact on the reduction of pollution from excavation. The research provides an initial insight into design options, potentials and limitations on the use of climbers for green roofs to guide future research and experimental verification.

Distancing people socially as a precautionary measure against the mushrooming of COVID-19’s health and economic crisis has deleteriously affected the performance of the eatery industry to a great extent. Many food outlets failed to cope up with crisis and opted to move out, and many still vie to survive through pandemic. It becomes vital for researchers to understand what factors influence the performance and survival of eateries during the pandemic? The study makes an attempt to fabricate new factors which affect the performance and contribute significantly towards the survival of eateries in this new COVID-19-prone world.

The present study is a cross-sectional analysis with the sample of 150 eateries from the walled city of Punjab (India), i.e. Amritsar. Factor analysis is employed to scrutinise the factors which influence the performance of eateries during the pandemic, and to analyse factors which contribute significantly for the survival of eateries, logistic regression is performed.

The empirical analysis reveals that at prior psychological factor, followed by turnover factor, external factor, financial factor and marketing factor influence the performance of eateries during the pandemic. Only three factors, namely turnover factor, external factor and financial factor, turned up to be significant towards the survival rate of an eatery. The marketing factor which is a crucial contributor for survival of business in literature has turned out to be insignificant during the times of pandemic.

With the arrival of pandemic, the preference of people has changed, and the business environment in which entities operate has turned more complex. The present study is one of the pioneer attempts to evaluate whether the factors responsible for performance or survival of an eatery during normal times is relevant during the pandemic as well. The study contributes to the literature of eatery industry by adding a new variable namely psychological factor, i.e. changes witnessed in customers’ preference to visit an eatery.
