Authors: Dai Ying , Hwang Shyh-Huei
Published: September 2021

Various brands of bamboo crafts created by youths have emerged in Zhushan Township, Taiwan. With the special bamboo materials available in Zhushan Township as their core, these brands have created different types of social innovations through their management, design, and mechanical knowledge. The results indicate the following: (1) The youths advocate for causes such as the preservation of culture, mutually beneficial situations, sustainable local development, and environmentally friendly lifestyles. The youths proposed innovative solutions for these causes, such as establishing a guesthouse, revitalizing unused space, creating opportunities for dialogues, developing bamboo-based environmentally friendly products, and holding local activities; (2) the youths constructed a model for internal cooperation and enhancement, revitalization, and marketing Zhushan Township; (3) the youths advocated for various social values, utilized social capital, and proposed innovative solutions through diversified participation and the creation of new relationships, allowing different communities to generate a group dynamic to resolve social problems and achieve sustainability together. This study aids in the facilitation of sustainable management of township micro-enterprises by innovating products and service modes through social capital and social value. At the same time, local and common social innovation modes are connected to provide a reference for the social innovation of micro-enterprises.

Fisheries and the aquaculture sector can play a significant role in the achievement of several of the goals of the 2030 Sustainable Development agenda. However, the current COVID-19 situation can negatively impact the fisheries sector, impeding the pace of the achievement of development goals. Therefore, this paper highlighted the performance and challenges of the fisheries sector in Bangladesh, emphasising the impact of COVID-19 and the significance of this sector for achieving the Sustainable Development Goals (SDGs), through primary fieldwork and secondary data. The total fish production in the country has increased more than six times over the last three decades (7.54 to 43.84 lakh MT) with improved culture techniques and extension services. Inland closed water contributions have increased to 16%, while inland open water has declined to 10%, and marine fisheries have dropped to 6% over the past 18 financial years (2000–2001 to 2018–2019). COVID-19, a significant health crisis, has also affected various issues associated with aquatic resources and communities. Transportation obstacles and complexity in the food supply, difficulty in starting production, labour crisis, sudden illness, insufficient consumer demand, commodity price hikes, creditor’s pressure, and reduced income were identified as COVID-19 drivers affecting the fisheries sector. The combined effect of these drivers poses a significant threat to a number of the SDGs, such as income (SDG1), nutrition (SDG2), and food security (SDG3 and SDG12), which require immediate and comprehensive action. Several recommendations were discussed, the implementation of which are important to the achievement of the SDGs and the improved management of the aquatic sector (SDG14—life below, and SDG16—life above water).

Published: September 2021

This study was designed to examine the structural relationships among tourists’ participation motivations, the value co-creation process (VCCP), and value co-creation behavior (VCCB) in terms of in-role and extra-role contributions. Based on a comprehensive review of literature, participation motivations were measured with four constructs, including need for uniqueness, need for self-control, need for social interaction, and need for leisure and entertainment. Research participants (N = 445) who had participated in two or more marathon events in China were recruited to respond to an on-site or online survey. Conducting structural equation modeling analyses, three motivational factors of need for uniqueness, need for social interaction, and need for leisure and entertainment were found to exert significant (p < 0.05) and positive impact on VCCP, which in turn had significant (p < 0.05) influence on in-role and extra-role contributions associated with VCCB. Discussions are centered on promoting specific areas of participants’ motivations in an effort to empower and energize the process of value co-creation and to ultimately activate and sustain participants’ in-role and extra-role behaviors.
Breaking Brands: New Boundaries in Rural Destinations
Authors: Paulino Isabel , Prats Lluís , Domènech Antoni
Published: September 2021

Tourism destinations are generally delimited and branded based on administrative boundaries, which act as artificial barriers that may reduce the competitiveness of the tourism sector. Increasingly, literature is taking a demand perspective (i.e., tourist spatial behaviour) when identifying and promoting destinations. This perspective can help to promote destinations more efficiently, particularly in rural areas, where most tourism flows depend on private vehicle and which do not take into account administrative boundaries. These flows are therefore highly conditioned by the geography of the area, hosting capacity and the cumulative effect of attractions. This research centres on brand creation from a tourist perspective, particularly how tourists consume a destination. Els Ports (Spain), a rural mountain area divided into multiple administrative divisions, each marketing its own brand, is taken as a case study. Recently, destination managers have seen the opportunity for regional cooperation and taken steps to cross traditional boundaries to market the area better. This study uses GIS techniques to compare tourist travel patterns with brand boundaries and new cooperative initiatives. The findings provide material for discussion on the branding strategy of Els Ports and the need to rebrand rural tourism destinations into functional tourism areas.
How Relevant Are Direct Emissions of Microplastics into Freshwater from an LCA Perspective?
Authors: Salieri Beatrice , Stoudmann Natasha , Hischier Roland , Som Claudia , Nowack Bernd
Published: September 2021

Microplastics are ubiquitous in ecosystems and a lot of research is being performed to understand their environmental fate and effects on organisms. However, the release and impact of MP has so far not been considered in LCA studies. This is due to missing information on the inventory side about microplastic releases and missing Characterization Factors to quantify the effects of MP. The goal of this study was to elucidate the relevance of MP release into freshwaters from an LCA perspective, by using worst-case assumptions. In accordance with the USEtox framework, an interim and simplified Characterization Factor for the impact category of freshwater ecotoxicity was calculated to be 3231 PAF·m3·d·kg−1. Applying this Characterization Factor, two LCA case studies were conducted, one on a polyester T-Shirt and one with a shower gel containing microplastics. The results show a small contribution of microplastics to the freshwater ecotoxicity for a scenario with state-of-the-art wastewater treatment. Different scenarios varying in microplastic release and removal during wastewater treatment and a sensitivity analysis of the Characterization Factor allowed identifying the potential range of the microplastic contribution to the overall ecotoxicity. In conclusion, the inclusion of microplastic release into LCA only marginally influences the overall environmental effects of the two products in the LCA case studies.
Circularity for Electric and Electronic Equipment (EEE), the Edge and Distributed Ledger (Edge&DL) Model
Authors: Andersen Terje , Jæger Bjørn
Published: September 2021

In the transition to a circular focus on electric and electronic products, manufacturers play a key role as the originators of both the products and the information about the products. While the waste electric and electronic equipment (WEEE) directive’s contemporary focus is on handling the product as waste after its end of life, the circular economy focuses on retaining the product’s value with a restorative system. The polluter-pays principle requires producers of pollution to bear the costs of handling the pollution, leading to the extended producer responsibility (EPR) principle. This requires manufacturers to change their focus from their current passive role of out-sourcing end-of-life treatment to taking explicit responsibility for product management over an extended period of time. This paper investigates how a manufacturer can assume its responsibility to achieve circularity for its products. Based on our findings, three fundamental circularity principles, the circular electric and electronic equipment (CEEE) principles, for manufactures of electronic and electrical equipment are defined: (1) Serialize product identifiers, (2) data controlled by their authoritative source at the edge, and (3) independent actors’ access to edge data via a distributer ledger are the foundation of the Edge and Distributed Ledger (Edge&DL) model. We demonstrate the model through a case study of how to achieve circularity for lighting equipment. The CEEE principles and the demonstrated model contribute to building new circularity systems for electronic and electric products that let manufacturers undertake their extended product responsibility.

Published: September 2021

Global warming has become an increasing challenge due to the impact of human activities on the environment. In this regard, university campuses with various activities and departments have a great impact on the environment. Ecological Footprint Analysis (EFA) is a natural resource depletion assessment tool, with a high level of accuracy, that measures the impact of human activities on the environment. Considering the Ecological Footprint (EF) capabilities, this study developed a method to assess the environmental impacts of a university campus using component-based parameters. The goals of the study are to explore the effective components of EF and to propose some policy guidelines to diminish the human impacts on the environment on university campuses. Five components, including natural gas and electricity consumption, water and food usage, and waste production, were measured in a survey from 2013 to 2016 at the building scale. The mean EF of the campus was 16,484 global hectares (gha). Fossil fuel energy had the highest level of environmental impact with 70.73%, followed by waste production and food and water usage with 26.87%, 1.28%, and 1.12%, respectively. The results demonstrate that the EF Index (EFI) of the case study campus was −0.82, which reveals an unsustainable performance. The EF results were illustrated on an Ecological Footprint Map (EFM), which shows the east and west parts of the camps were more unsustainable.

Published: September 2021

Field crop production must adapt to the challenges generated by the negative consequences of climate change. Yield loss caused by abiotic stresses could be counterbalanced by increasing atmospheric CO2 concentration, but C3 plant species and varieties have significantly different reactions to CO2. To examine the responses of wheat, barley and oat varieties to CO2 enrichment in combination with simulated drought, a model experiment was conducted under controlled environmental conditions. The plants were grown in climate-controlled greenhouse chambers under ambient and enriched (700 ppm and 1000 ppm) CO2 concentrations. Water shortage was induced by discontinuing the irrigation at BBCH stages 21 and 55. Positive CO2 responses were determined in barley, but the CO2-sink ability was low in oats. Reactions of winter wheat to enriched CO2 concentration varied greatly in terms of the yield parameters (spike number and grain yield). The water uptake of all wheat cultivars decreased significantly; however at the same time, water-use efficiency improved under 1000 ppm CO2. Mv Ikva was not susceptible to CO2 fertilization, while no consequent CO2 reactions were observed for Mv Nádor and Mv Nemere. Positive CO2 responses were determined in Mv Kolompos.
A Trajectory Optimization Strategy for Connected and Automated Vehicles at Junction of Freeway and Urban Road

Published: September 2021

The phenomenon of stop-and-go traffic and its environmental impact has become a crucial issue that needs to be tackled, in terms of the junctions between freeway and urban road networks, which consist of freeway off-ramps, downstream intersections, and the junction section. The development of Connected and Automated Vehicles (CAVs) has provided promising solutions to tackle the difficulties that arise along intersections and freeway off-ramps separately. However, several problems still exist that need to be handled in terms of junction structure, including vehicle merging trajectory optimization, vehicle crossing trajectory optimization, and heterogeneous decision-making. In this paper, a two-stage CAV trajectory optimization strategy is presented to improve fuel economy and to reduce delays through a joint framework. The first stage considers an approach to determine travel time considering the different topological structures of each subarea to ensure maximum capacity. In the second stage, Pontryagin’s Minimum Principle (PMP) is employed to construct Hamiltonian equations to smooth vehicle trajectory under the requirements of vehicle dynamics and safety. Targeted methods are devised to avoid driving backwards and to ensure an optimal vehicle gap, which make up for the shortcomings of the PMP theory. Finally, simulation experiments are designed to verify the effectiveness of the proposed strategy. The evaluation results show that our strategy could effectively militate travel delays and fuel consumption.

Authors: Vizentin Goran , Glujić Darko , Špada Vedrana
Published: September 2021

Fiber reinforced polymer (FRP) composites coupons were exposed to real sea environment to assess the influence on the mechanical behavior of composite materials used in the construction of marine structures. Real-life sea environment conditions were opted for instead of the more common simulated and laboratory versions of seawater in the attempt to obtain more realistic structural modeling environmental input design parameters for marine structures. Exposure was performed over prolonged time span instead of the usual accelerated tests. Epoxy and polyester resins, reinforced with glass fibers in three fiber layout configurations, were used to manufacture standardized tensile testing coupons. Mass changes due to seawater absorption, microorganism growth, changes in tensile strength (standard tensile tests), and surface morphology of the coupons were evaluated after 6- and 12-month long periods of submersion in the sea in the Rijeka bay, Croatia. All specimens showed mass increase due to water absorption and growth of attached algae and sea microorganisms. Various levels of reduction in tensile strength, depending on the fiber layout configurations, were observed. Significant changes in the matrix material structure were noticed, effectively producing “voids”. Based on these results, sustainability of FRP composites in marine environment is addressed and discussed.
Iron and Aluminium Production Wastes as Exclusive Components of Alkali Activated Binders—Towards a Sustainable Alternative
Authors: Cristelo Nuno , Castro Fernando , Miranda Tiago , Abdollahnejad Zahra , Fernández-Jiménez Ana
Published: September 2021

The sustainability of resources is becoming a worldwide concern, including construction and building materials, especially with the alarming increase rate in global population. Alternative solutions to ordinary Portland cement (OPC) as a concrete binder are being studied, namely the so-called alkali-activated cements (AAC). These are less harmful to the environment, as lower CO2 emissions are associated with their fabrication, and their mechanical properties can be similar to those of the OPC. The aim of developing alkali-activated materials (AAM) is the maximization of the incorporated recycled materials, which minimises the CO2 emissions and cost, while also achieving acceptable properties for construction applications. Therefore, various efforts are being made to produce sustainable construction materials based on different sources and raw materials. Recently, significant attention has been raised from the by-products of the steelmaking industry, mostly due to their widespread availability. In this paper, ladle slag (LS) resulting from steelmaking operations was studied as the main precursor to produce AAC, combined with phosphating bath sludge—or phosphate sludge (PS)—and aluminium anodising sludge (AS), two by-products of the surface treatment of metals, in replacement rates of 10 and 20 wt.%. The precursors were activated by two different alkaline solutions: a combination of commercial sodium hydroxide and sodium silicate (COM), and a disposed solution from the cleaning of aluminium extrusion steel dies (CLE). This study assesses the influence of these by-products from the steelmaking industry (PS, AS and CLE) on the performance of the alkali-activated LS, and specifically on its fresh and hardened state properties, including rheology, heat of hydration, compressive strength and microstructure and mineralogy (X-ray diffraction, scanning electron microscopy coupled with energy dispersive spectroscopy and Fourier transform infra-red. The results showed that the CLE had no negative impact on the strength of the AAM incorporating PS or/and AS, while increasing the strength of the LS alone by 2×. Additionally, regardless of the precursor combination, the use of a commercial activator (COM) led to more fluid pastes, compared with the CLE.

Published: September 2021

Teaching students awareness about sustainable mobility has been lacking to date. There is a need to expand the themes being addressed in order to achieve a change in attitude. Society needs to design a curriculum that teaches about sustainable mobility to guarantee a better environment for future generations. This article presents the most important results of an experiment based on gamification to promote the education of sustainable mobility in primary school classrooms. This new teaching method, aimed at children aged 10–12 years old, applies non-gambling play metaphors to real-life tasks to motivate a change in attitude. The didactic approach was developed using the ClassCraft platform to create specific activities that consider the environmental, economic, and social aspects of sustainable mobility. The initial analysis revealed a perception about sustainable mobility that focused on environmental problems with very little input on the economic and social aspects. The experience has shown that by using the gamified ClassCraft tool applying structured activities about all aspects of sustainable mobility, the pupils acquired new concepts that clarified the social and economic components and began to develop a conscience about how to become an active part in behavioural change.

Published: September 2021

Attention Deficit Hyperactivity Disorder (ADHD) has a high comorbidity with specific learning disorders (SLD). Children with ADHD and children with SLD show specific cognitive deficits. This study aims to examine similarities and differences between cognitive profiles of children with ADHD + SLD, children with SLD only, and a control group to find out whether specific or shared deficits can be identified for the groups. We compared the WISC-V profiles of 62 children with ADHD and SLD (19 girls, M-age = 10.44; SD = 2.44), 35 children with SLD (13 girls, M-age = 10.21; SD = 2.11) and 62 control children without ADHD or SLD (19 girls, M-age = 10.42; SD = 2.39). The ADHD + SLD group performed worse than the control group in the WISC-V indices WMI, PSI, FSIQ, AWMI, CPI and worse than the SLD group in these indices and the VCI, NVI and GAI. Therefore, compared to children with SLD, children with ADHD + SLD did not show specific impairments in any particular cognitive domain but rather non-specific impairment in almost all indices. Hence, the WISC-V is suited to depict the cognitive strength and weaknesses of an individual child as a basis for targeted intervention.
Voluntary Disclosure of Carbon Emissions and Sustainable Existence of Firms: With a Focus on Human Resources of Internal Control System
Authors: Lee Jaehong , Kim Suyon , Kim Eunsoo
Published: September 2021

The purpose of this study is to examine the relationship between the voluntary disclosure of carbon emissions and firm value. In addition, we examine whether the human resources of the internal control system affect the relationship between the voluntary disclosure of carbon emissions and firm value with data from the Korean stock market from 2014 to 2019. This study shows that the firms that voluntarily disclose information on carbon emissions increase their value. Additionally, the sufficient number and working experience of internal control personnel in each accounting, financing, and information technology department positively affects the relationship between voluntary disclosure and firm value. We additionally find an effect of the awareness level on climate change on firm value. That is, firms that are active on climate change rather than merely disclosing information. Finally, we find the positive role of Environment, Social and Governance (ESG), implying a superior management environment that leads to better disclosure practices.

Authors: Türkakın Osman Hürol , Arditi David , Manisalı Ekrem
Published: September 2021

Resource-constrained project scheduling (RCPS) aims to minimize project duration under limited resource availabilities. The heuristic methods that are often used to solve the RCPS problem make use of different priority rules. The comparative merits of different priority rules have not been discussed in the literature in sufficient detail. This study is a response to this research gap. It compares 17 heuristic priority rules and seeks the best performing heuristic priority rule. This is the first study ever that compares heuristic priority rules by considering combinations of variations in (1) resource allocation procedures, (2) number of activities, (3) number of resource constraints, and (4) resource supply levels. The objective is to understand the relative merits of heuristic rules used in solving the RCPS problem. The findings indicate that the “minimum late finish time” rule generates the shortest predicted project duration when used in parallel resource allocation, whereas the “minimum late start time”, “minimum late finish time”, and the “highest rank of positional weight 2” rules perform best in serial resource allocation. It was also found that parallel resource allocation is slightly superior to serial resource allocation in most instances.

Published: September 2021

The Food and Agriculture Organization of the United Nations (FAO) launched the conservation initiative of the Globally Important Agricultural Heritage Systems (GIAHS) in 2002, providing a new solution to current global problems such as widening gap between rich and poor, environmental pollution, biodiversity destruction and degradation of agro-ecological functions. However, since the implementation of GIAHS, few studies have evaluated the role of GIAHS in regional sustainable development. To fill this research gap, this paper attempts to build an evaluation index system that integrates economic, social and environmental sustainability by matching the 169 subgoals and 232 indices of the UN Sustainable Development Goals (SDGs) with five FAO-GIAHS selection criteria and selecting the indices. The index weights are determined through Delphi method (expert scoring) and Analytic Hierarchy Process (AHP). Then the GIAHS site of the Kuaijishan Ancient Chinese Torreya Community in Shaoxing City, Zhejiang Province is taken as an example for evaluation to enhance the empirical study. The results show that the comprehensive score for this heritage site is 77.90 points, of which economic, social and environmental sustainability scores 88.27, 86.12 and 69.71 points respectively, showing a descending trend. Thus, ecological protection of the Kuaijishan Ancient Chinese Torreya Community should be strengthened and be given prominence in the future. As for the contribution to further research, this SDGs-based GIAHS sustainability evaluation framework can serve as an important guide for assessing the approaches and effects of GIAHS in promoting the achievement of the SDGs. It can also be used for future international GIAHS sustainability assessment and comparison and provide a basis for adjusting the development model of GIAHS sites.
Cognitive Biases in Building Energy Decisions
Authors: Rakitta Maic , Wernery Jannis
Published: September 2021

Research on sustainability in the building sector currently focuses mainly on technical solutions while little attention is given to how behaviour influences the uptake of these solutions. Bounded rationality may have a significant impact on the effective implementation of more sustainable technologies that are already available. However, empirical evidence on the effects of bounded rationality in the building sector, such as cognitive biases, is still lacking. Here, we present an empirical investigation of four cognitive biases in the building environment, namely the framing, anchor, default, and decoy effect. For that, energy-related decisions situations were presented to approximately 270 participants in an online survey. Our results show that awareness of greenhouse gas emissions from buildings can be raised through framing that the willingness to pay more for an energy-efficient home can be increased by presenting it as default, and that the choices can be shifted towards more energy-efficient appliances by using a decoy. The hypothesis that anchoring increases the willingness to pay more for the installation of a solar system could not be supported. These findings decrease the lack of empirical data on cognitive biases in the context of buildings and further indicate the potential of choice architecture in the building environment. The influence of cognitive biases in energy-related decisions should be used to increase the adaptation of sustainable technologies.
Comprehensive Assessment of Thermal Comfort and Indoor Environment of Traditional Historic Stilt House, a Case of Dong Minority Dwelling, China
Authors: Jin Yue , Zhang Ning
Published: September 2021

The stilt house is one of the most representative of Chinese architecture among national minority traditional dwellings, most of which are located in mountainous regions whose climate is characterized by hot summers and cold winters. Moreover, it is widely distributed in Southeast Asian countries, such as Thailand, Laos, Cambodia, etc., as well as tropics like Hawaii, Guam. These kinds of dwellings have unique architectural aesthetics as well as high climate adaptability. However, because of their remote locations and rapid disappearance in urbanization, few studies have focused on their real indoor environment and thermal comfort. More studies were engaged in their architectural aesthetics and space patterns. In this study, based on the measurement and evaluation of residential natural lighting, ventilation, air quality, and thermal comfort in traditional stilt Dong village houses, the air temperature, humidity, CO2 and PM2.5 concentrations, wind speed, direction, and other variables are monitored and analyzed. Results show that the inhabitants have a higher thermal comfort adaptation than urban residents under natural ventilation. Meanwhile, the humidity of Dong stilt dwelling can reach a satisfactory level within 24 h except for the morning period. The satisfaction of the acoustic environment needs to be improved via reasonable structural maintenance.
An Empirical Test of Brand Love and Brand Loyalty for Restaurants during the COVID-19 Era: A Moderated Moderation Approach
Authors: Pan Huifeng , Ha Hong-Youl
Published: September 2021

Although brand love–loyalty relationships can deepen, the literature does not include systematic and empirical investigations demonstrating when perceived value and relationship duration are valuable in enhancing the brand love–loyalty relationship. This study investigates the effects of relationship duration, perceived value, and restaurant type on the relationships between brand love and brand loyalty during the coronavirus disease of 2019 (COVID-19) pandemic. In particular, hedonic value rather than utilitarian value is hypothesized to negatively enhance the relationship between brand love and brand loyalty when consumers continue to have long-lasting relationships with a restaurant brand. Using data collected from an online research firm in Korea, the findings revealed that brand love negatively influences brand loyalty. However, the impact of brand love on brand loyalty increases when customers seek hedonic value. Our findings also demonstrate that consumers who sought hedonic value strengthened the brand love–loyalty link compared to consumers who sought utilitarian value, particularly one with a short-lasting relationship. Consumers who sought utilitarian value through a long-lasting relationship strengthened the same relationship, although the increased correlation was not statistically significant. Furthermore, brand loyalty gradually decreases at fine-dining restaurants, whereas it sharply increases at takeaway restaurants.

Authors: Medina-Sanchez Edgar Herberto , Mikusova Miroslava , Callejas-Cuervo Mauro
Published: September 2021

An increasing availability and reliability of open-source geographical resources, options in design of mobile applications together with smartphones of a high quality, featuring top cameras and number of sensors, bring us an extraordinary opportunity to provide the visually impaired people with relevant and comprehensible information on their vicinity, and thus to improve their mobility in a sustainable environment. The paper presents an interactive tool based on a mobile application created for mobile devices with Android operation system, and on using the augmented reality. It is a tool to support safe and efficient mobility of blind people and people with severe visual limitations in a sustainable urban environment. The essential benefit from using this tool lies in preventing risky, possibly dangerous and hardly accessible places. The first part briefly presents the problem of the visually impaired including the forms of the visual impairment, personal and economic costs for the entire society and the importance of improving the mobility of this group of people. The second part of the paper introduces the current state of the problem being solved as well as some basic tools which were developed to bring the surrounding environment closer to the visually impaired. Further, the process of the mobile application development is described. The application is meant to indicate information on places where the visually impaired users of the application are present while walking in an external environment (including the distance to their destination); the pilot testing of the application by a selected groups of the visually impaired is introduced, too.
Cultural Landscapes under the Threat of Climate Change: A Systematic Study of Barriers to Resilience
Authors: Aktürk Gül , Dastgerdi Ahmadreza Shirvani
Published: September 2021

Cultural landscapes reflect a cultural group’s continuous and evolved interactions with natural resources and the environment. By now, climate change has become the most significant threat to cultural landscapes, e.g., food security, water scarcity, and displacement. The cultural and natural heritage of cultural landscapes can enhance their value as integrated systems and offer solutions to the challenges brought by climate change. Although exploring tangible impacts of climate change has received sufficient attention in cultural landscapes, a systematic understanding of the main barriers has been overlooked in building climate resilience in cultural landscapes. This paper aimed to explore the main barriers to building climate resilience in cultural landscapes. The research methodology was based on the content analysis of 359 documents published between 1995 and 2020. The results revealed that the integrated approach in documentation and assessments was the most quoted technical barrier. In addition, the lack of a regulatory framework for supporting effective collaboration and cooperation has been discussed as the most significant institutional obstacle to climate resilience in cultural landscapes.

Published: September 2021

We are entering a new, unprecedented global economic and social era following the COVID-19 pandemic, in which there will be opportunities and threats for the goods and services provided. Traditional foods (TFs) could have their chances in the new food chain which will be developed, as long as they become the food of choice for the consumers of the future. This paper investigates consumers’ trust in Greek TFs, and northwest Greek TFs, in order to assess their potential consumption in the new economy. Trust was tested using the variables of safety, healthiness, sustainability, authenticity and taste, assessing consumers’ confidence and satisfaction with the TFs, their raw materials, and the technologies used for their production. A self-response questionnaire survey was carried out in May and June 2021 on a sample of 548 participants through the Google platform. In order to analyze the data, basic descriptive statistical tools were used, combined with crosstabs and chi-square tests. The results show that the participants trust the Greek TFs because they “strongly agree” by an average of 20%, and “agree” by an average of 50% that they are safe, healthy, sustainable, authentic and tasty. A similar pattern was recorded for the regional northwest Greek TFs as well. These results indicate that TFs could be the food of choice because they bear consumers’ trust in the coming “new normality”, where trust will be a major factor of choice for the purchase of goods and services.
De Re Metallica: An Early Ergonomics Lesson Applied to Machine Design in the Renaissance
Authors: Trujillo Francisco Javier , Claver Juan , Sevilla Lorenzo , Sebastián Miguel A.
Published: September 2021

The Renaissance treatise De Re Metallica (Georgius Agricola, 1556) is one of the first works that deals in detail with the state of the art of metal mining, compiling the main techniques and mechanical devices used in this industrial activity at that time. An advanced knowledge of the human–machine set is observed in this treatise, from a mechanical and ergonomics point of view. The main objective of this work is to carry out an ergonomics analysis of one of the mechanical devices collected in the sixth book of this treatise. It is intended to show that there was a certain concern for ergonomics in the Renaissance, long before the first appearance of this concept. Specifically, a mine water extraction pump, powered by three different systems, is analyzed. Current ergonomics assessment methods have been used to perform this comparative analysis. The postural load has been assessed by the rapid upper limb assessment (RULA) and the rapid entire body assessment (REBA). The Check List OCRA (occupational repetitive action) has been used to perform the analysis of repetitive movements. The results have shown an evolution of the machine, not only on a mechanical level, but also in movements, postures, and safety of the operator for the three methods applied. It is, therefore, an example of practical and real ergonomics applied to machine design dating from the 16th century. In addition, this work may be a very interesting tool for teaching, since it allows showing examples of ergonomics in productive areas related to historical context.

In this paper, we employ a target-oriented approach to analyze the multi-attribute route choice decision of travelers in the stochastic tolled traffic network, considering the influence of three attributes, which are (stochastic) travel time, (stochastic) late arrival penalty, and (deterministic) travel cost. We introduce a target-oriented multi-attribute travel utility model for this analysis, where each attribute is assigned a target by travelers, and travelers’ objective is to maximize their travel utility that is determined by the achieved targets. Moreover, the interaction between targets is interpreted as complementarity relationship between them, which can further affect their travel utility. In addition, based on this travel utility model, a target-oriented multi-attribute user equilibrium model is proposed, which is formulated as a variational inequality problem and solved with the method of successive average. Target for travel time is determined via travelers’ on-time arrival probability, while targets for late arrival penalty and travel cost are given exogenously. Lastly, we apply the proposed model on the Braess and Nguyen–Dupuis traffic networks, and conduct sensitivity analysis of the parameters, including these three targets and the target interaction between them. The study in this paper can provide a new perspective for travelers’ multi-attribute route choice decision, which can further show some implications for the policy design.

Spatiotemporal water quality tendencies before and after total maximum daily load (TMDL) implementation in the Hangang basin were analyzed to determine the water quality improvement resulting from the TMDL policy. The periodicities of water quality indicators were also analyzed and water quality characteristics corresponding to different unit watershed units were identified in terms of pollution source. Considering five water quality indicators, including biochemical oxygen demand and total phosphorus, it was observed that water quality indicator concentrations were low in the upstream areas of the Bukhangang and Namhangang watersheds. However, they were high between the downstream areas of the Namhangang watershed and the Imjingang watershed and in the Hangang downstream and Jinwicheon watersheds. Additionally, the concentrations of water quality indicators in most of the unit watersheds where TMDL had been implemented decreased after TMDL implementation. However, increasing tendencies in the concentrations of water quality indicators continued to be observed in some of the watershed units in the upstream areas of the Bukhangang and Namhangang watersheds, possibly because these watersheds are affected by nonpoint source pollution owing to rainfall. Therefore, in the future, it would be necessary to implement policies that take these findings into consideration.

This paper describes the studies conducted in order to identify the limits of ultrasonic exposure’s effect on the fine particle coagulation process. It has been established as a result of the studies that ultrasonic exposure with a sound pressure level of 160 dB is capable of ensuring coagulation of particles sized 2.5 µm with efficiency δ = 83%. An increase of the coagulation up to 13% is induced with generation of swirling flows. The suggested approach to increasing the coagulation efficiency owing to vortex-type flows between the radiating and reflecting surfaces ensures efficiency of coagulation δ = 96 %. The implementation of this approach has shown that with generation of vortex-type acoustic flows, it makes the most sense for a concentration of particles of 18×10−3 g/m3. Incremental efficiency at such concentrations amounts to 50%.

The synthesis of polyhydroxybutyrate (PHB) by photosynthetic non-sulfur bacteria is a potential approach for producing biodegradable plastics. In this work, acetate was used as a single carbon source to study the effect on PHB formation in Rhodopseudomonas sp. cultured in a cylindrical four-liter photobioreactor under semi-continuous mode. The cultivation process is divided into a symmetrical growth phase and a PHB accumulation phase separated temporally. The symmetrical growth phase (nutrient sufficient conditions) was followed by a sulfur-limited phase to promote PHB accumulation. The main novelty is the progressive lowering of the sulfur concentration into Rhodopseudomonas culture, which was obtained by two concomitant conditions: (1) sulfur consumption during the bacterial growth and (2) semi-continuous growth strategy. This caused a progressive lowering of the sulfur concentration into Rhodopseudomonas culturedue to the sulfur-free medium used to replace 2 L of culture (50% of the total) that was withdrawn from the photobioreactor at each dilution. The PHB content ranged from 9.26% to 15.24% of cell dry weight. At the steady state phase, the average cumulative PHB was >210 mg/L. Sulfur deficiency proved to be one of the most suitable conditions to obtain high cumulative PHB in Rhodopseudomonas culture.
An Examination of Factors Influencing Small Proton Chemical Shift Differences in Nitrogen-Substituted Monodeuterated Methyl Groups

Monodeuterated methyl groups have previously been demonstrated to provide access to long-lived nuclear spin states. This is possible when the CH2D rotamers have sufficiently different populations and the local environment is chiral, which foments a non-negligible isotropic chemical shift difference between the two CH2D protons. In this article, the focus is on the N-CH2D group of N-CH2D-2-methylpiperidine and other suitable CH2D-piperidine derivatives. We used a combined experimental and computational approach to investigate how rotameric symmetry breaking leads to a 1H CH2D chemical shift difference that can subsequently be tuned by a variety of factors such as temperature, acidity and 2-substituted molecular groups.
Is Face Age Mapped Asymmetrically onto Space? Insights from a SNARC-like Task
Authors: Dalmaso Mario , Vicovaro Michele
Published: September 2021

The magnitude associated with a stimulus can be spatially connoted, with relatively smaller and larger magnitudes that would be represented on the left and on the right side of space, respectively. According to recent evidence, this space–magnitude association could reflect specific brain asymmetries. In this study, we explored whether such an association can also emerge for face age, assuming that responders should represent relatively younger and older adult faces on the left and on the right, respectively. A sample of young adults performed a speeded binary classification task aimed at categorising the age of a centrally placed adult face stimulus as either younger or older than the age of a reference face. A left-side and a right-side response key were used to collect manual responses. Overall, older faces were categorised faster than younger faces, and response latencies decreased with the absolute difference between the age of the target stimulus and the age of the reference, in line with a distance effect. However, no evidence of a left-to-right spatial representation of face age emerged. Taken together, these results suggest that face age is mapped onto space differently from other magnitudes.
