Partner Selection Strategies in Global Business Ecosystems: Country Images of the Keystone Company and Partner Companies on the Brand Quality Perception
Authors: Bang Dongock , Lee Jiwon , Shin Matthew Minsuk
Published: December 2021

Consumers perceive brand quality from the country of origin of the brand. Global business ecosystems represent multiple countries such as the country of the keystone company and the country of the assembly companies. Thus, the brands of global business ecosystems have multiple countries of origin. This study aims to examine the impacts of the country images of the keystone company and assembly companies on consumers’ brand quality perceptions. In addition, depending on the assembly partner selection strategies of forming a global business ecosystem, the characteristics of the associated countries with the business ecosystem may change. The keystone company may select an assembly partner from a developing country or from a developed country. These two cases are compared to examine the impacts of the combined country images of the keystone and assembly companies. To do so, this study surveys Vietnamese consumers’ perceptions of the brand Hyundai Motor, the country images of South Korea as the country of the keystone company, India as the assembly partner from the developing country, and USA as the assembly partner from the developed country. The collected data were analyzed using a structural equations modeling method and results are discussed with theoretical and managerial implications.

A Study on the Sustainable Use Intention of Restaurant Companies Using the Information Attributes of SNS: The Dual Process Theory
Authors: Lee Sangmook , Bae Gumkwang , Kim Hyojin
Published: December 2021

This study was conducted to define detailed factors by combining the factors of SNS (social network services) information attributes and dual processing process theory and to investigate the relationship between customer satisfaction, brand attitude, and sustainable use intention. An empirical analysis was conducted using data collected from 361 participants who have experience in SNSs for searching for restaurant information. The major results are as follows: First, two intuitive SNS information attributes (reliability and liveliness) and two analytical attributes (usefulness and conciseness) have a significant positive influence on customer satisfaction to use an SNS. In particular, the reliability was the most significant antecedent of the SNS information attributes in this study. In addition, the current study verified the significant relationships among customer satisfaction, brand attitude, and sustainable use intention. Based on these research results, it was verified that SNS information characteristics are important attributes in eliciting customer satisfaction, attitude toward the brand, and sustainable use intention from customers. This study will contribute to providing various practical implications to establish valuable marketing strategies.

Authors: Ortiz-Marcos Isabel , Ballesteros-Sánchez Luis Ignacio , Hernández Bayo Araceli , Rodríguez-Rivero Rocío , Guillerme Gwenaelle
Published: December 2021

This paper outlines a contemporary understanding of global competence for engineers, as understood by European engineering companies, and presents the main findings of the Tools for Enhancing and Assessing the Value of International Experience for Engineers (TA VIE) project, launched in 2018. Situational judgment tests (SJTs), or scenario-based approaches were used to measure eleven global competences. Researchers designed the scenarios and contrasted them designing a dictionary of competences containing: the definition of each competence as well as the five levels for each competence (defined by objective behaviours that could be observed). The measurement of competences is performed through a web platform where all data are collected. Nearly 300 students from different countries fulfilled the questionaries, and the results show that students with mobility, have, in general terms, a higher level of global competence than those without international mobility. Communication and flexibility are the competences with higher impact when students enjoy an international experience.
Urban Containment Planning: Is It Effective? The Case of Portland, OR
Authors: Giovannoni Giulio
Published: December 2021

The paper attempts to evaluate Oregon’s and Portland’s growth management policies as for their tradeoffs between effectiveness in containing urban sprawl and impacts on housing markets and on property values. Carruthers argued that in order to correctly evaluate growth management policies, it is necessary to jointly consider their effects on urban development patterns, on land and housing markets, and on the fragmentation of land use controls. Nowadays, we have sufficient empirical research to evaluate the effects of Oregon’s growth management policies both on land markets and housing affordability and on urban development patterns. Therefore, the time has come to comprehensively reanalyze this longstanding case of public regulation. Once again, the issue of comparing grounded-on-planning–regulations’ effectiveness with grounded-on-price regulations’ effectiveness is at stake. The paper finds that urban-containment centralized-planning in Portland and Oregon have not been effective in containing sprawl and that price-based mechanisms are the most logical solution to the excess of sprawling urban growth.
Wealthy Private Investors and Socially Responsible Investing: The Influence of Reference Groups
Authors: Risi David , Paetzold Falko , Kellers Anne
Published: December 2021

Sustainable development requires a shift from traditionally invested assets to socially responsible investing (SRI), bringing together financial profits and social welfare. Private high-net-worth individuals (HNWIs) are critical for this shift as they control nearly half of global wealth. While we know little about HNWIs’ investment behavior, reference group theory suggests that their SRI engagement is influenced by their identification with and comparison to reference groups. We thus ask: how do reference groups influence the investment behavior of SRI-oriented HNWIs? To answer this question, we analyzed a unique qualitative data set of 55 semi-structured interviews with SRI-oriented HNWIs and industry experts. Our qualitative research found that, on the one hand, the family serves as a normative reference group that upholds the economic profit motive and directly shapes HNWIs to make financial gains from their investments at the expense of social welfare. On the other hand, fellow SRI-oriented HNWIs serve as a comparative reference group that does not impose any concrete requirements on social welfare performance, indirectly influencing SRI-oriented HNWIs to subordinate social concerns to financial profits. Our scholarly insights contribute to the SRI literature, reference group theory, and practice.
Corporate Social Responsibility Disclosure and Its Effect on Firm Risk: An Empirical Research on Vietnamese Firms
Authors: Thuy Cao Thi Mien , Khuong Nguyen Vinh , Liem Nguyen Thanh
Published: December 2021

The purpose of the study was to gather empirical evidence on the influence of corporate social responsibility (CSR) disclosure on firm risk of Vietnam’s publicly listed companies. We used adjusted OLS estimation and regression analysis with adjusted panel data for heteroskedasticity and/or autocorrelation to analyze the correlation using data from 225 listed companies on Vietnam’s stock market from 2014 to 2019. The study’s sample period is relatively recent in the emerging market, especially considering regulatory differences and the availability of voluntary disclosure requirements. The findings of research on the relationship between CSR and corporate risk are mixed, particularly in developing markets. Research findings reveal a negative and significant association between CSR and firm risk, implying that stronger CSR performance lowers a company’s risk. This aims to strengthen a research perspective of this connection in emerging countries. Following that, we discuss some policy implications for listed firms and regulators in CSR disclosure.
Towards Sustainable Knowledge Sharing Practices: An Analysis of Organizational Level Enablers
Authors: Cormican Kathryn , Meng Chen , Sampaio Suzana , Wu Qiong
Published: December 2021

Sustainable management activities focus on creating efficiencies and value for organizations. Scholars advocate that evaluating and enabling appropriate management interventions can pave the way for future competitive advantage and sustainability. Knowledge management is regarded as a key organizational resource and a means of gaining a sustainable competitive advantage. This is especially important in high-tech service organizations, which are under increasing pressure to capture, process and share knowledge efficiently. While much work has been conducted to advance our knowledge on good practices, there is a dearth of empirical evidence relating to organizational level enablers for knowledge sharing. We advocate that creating the conditions conducive to knowledge sharing influences an organization’s ability to sustain a long-term competitive advantage. Therefore, this current study extends the literature on knowledge management by exploring the questions of whether and how key organizational factors impact knowledge sharing, focusing on the role of trust, communication, reward systems and leadership. To do this, we analyzed prior work and generated hypotheses relating to relevant enablers. We then operationalized these constructs via a structured data collection instrument, which consisted of 27 measurable items. Empirical data were collected from 104 team members in a high-tech service organization in Ireland. Data were analyzed using a quantitative approach, and descriptive statistics, correlations and regression analyses are presented. Our research offers a persuasive body of evidence supporting the notion that trust, communication, reward systems, and leadership strongly impact knowledge sharing in organizations. Specifically, the findings reveal that employees are more willing to share their personal knowledge with those they trust, and carefully designed communication systems can enable knowledge sharing. Reward systems play an important role in affecting employees’ motivation to share knowledge, while empowering leadership and participatory leadership are two main drivers in promoting knowledge sharing. This research addresses a relatively unexplored area, has implications for sustainable management practices relating to organizational design and provides ideas for future research studies.
Research on the Impact of Environmental Regulations on Industrial Green Total Factor Productivity: Perspectives on the Changes in the Allocation Ratio of Factors among Different Industries
Authors: Yuan Jiaqi , Zhang Deyuan
Published: December 2021

This paper constructs a two-sector manufacturer model of endogenous technological progress. We analyze the impact of environmental regulations on the factor input and output of different industries. Then, we reveal the intermediary role of inter-industry factor allocation in the impact of environmental regulations on industrial green total factor productivity (GTFP). Finally, the paper uses panel data from 30 provinces in China’s industry from 2000 to 2017 to conduct empirical tests. We can draw the following conclusions: (1) The relative magnitude of the output compensation of the production department and the innovation compensation of the R&D department could change the impact of environmental regulations on the input and output of inter-industry factors, and the comprehensive effects of both input and output will affect the level of GTFP. (2) The curve of the direct impact of environmental regulations on GTFP is in an inverted “U” shape. However, the production factor allocation ratio can “reverse” the inhibitory effect of high-intensity regulations on GTFP. (3) The capital factor has a greater impact on the regulatory effect, but the labor factor has a more lasting impact on the regulatory effect. High-strength environmental regulations can enhance manufacturers’ preference for human capital. Therefore, formulating environmental regulatory policies oriented to improve the ratio of factor allocation, mixing different types of regulatory policies, and increasing investment in human capital are all conducive to accelerating the transformation and upgrading of China’s industrial structure and achieving high-quality development of the industrial economy.
Factors Influencing the Sustainability of Wood-Based Constructions’ Use from the Perspective of Users
Authors: Švajlenka Jozef , Kozlovská Mária
Published: December 2021

Traditional construction solutions face increasing competition from more ecological materials such as construction systems based on wood. Thanks to the numerous favourable properties of wood, wood construction enjoys great popularity and allows building economical and modern constructions that are durable and contribute to an ecological future. This study is motivated by the need for innovative solutions in construction and offers numerous findings based on examining actual constructions based on wood. By examining the interactions among selected factors of constructions and their users, the study reacts to the global challenges that call for increased efficiency and sustainability in construction. The examination of the interactions among the selected factors offers more extensive knowledge in the field of constructions based on wood and points towards possible innovative approaches for more sustainable housing and for a more efficient construction industry. The analyses showed that the key aspects that determine the sustainability of housing from the perspective of users are the standard of construction workmanship and construction time, which depend on the choice of construction system, cost-efficiency of use, and material composition and floor plan design. These aspects also interacted with other technical and design aspects, which also played an important role in the perception of housing sustainability.
A Systemic Perspective for Understanding Digital Transformation in Higher Education: Overview and Subregional Context in Latin America as Evidence
Authors: Cerdá Suárez Luis Manuel , Núñez-Valdés Karen , Quirós y Alpera Susana
Published: December 2021

Since virtual education has increased from a local to a global audience, it is of great importance to understand the role that cultural and social backgrounds play in the transition to digital education. Therefore, a review of preferences and evidence among different Latin American regions and nations increases understanding. This digital transformation can be assessed under several categories of cultural, social, and economic situations. Traditionally, universities are known as formal institutions with emerging education trends, but it is mandatory to address the managerial work and implications of the institutions themselves. Particularly, universities play a relevant role in understanding the effective digital transformation in communities, but the profile of the educational system is very important for configuring this process. This research points out the main dimensions that prevent societies from increasing their educational level. By using comparative data analysis and documentary references, this paper highlights a systemic perspective for understanding the digital transformation in higher education, but it also expands the range to managerial decisions about the role educational ecosystems play in this transformation. Moreover, this study provides an overview of how relational elements configure management in higher education institutions.
Public Perceptions of Waste Management in Sri Lanka: A Focus Group Study
Authors: Gudmann Knutsson Sophie , Asplund Therese , Höst Gunnar , Schönborn Konrad J.
Published: December 2021

The prevention, reduction, recycling and reuse of waste is promoted by the United Nation’s 2030 Agenda for Sustainable Development, but many countries lack both necessary resources and infrastructure for sound waste management. While literature pinpoints the need for an engaged public and suggests a range of factors and supportive actions that may impact citizens’ waste behaviour, qualitative in-depth studies for engaging in waste management practices remain scarce. This study aimed to investigate perceptions of waste management and underlying behaviours for waste practices in the context of household waste management in Sri Lanka. Six focus group interviews were held with 23 residents across 6 regions in Sri Lanka. A thematic analysis of the interview transcripts revealed perceptions of four waste management systems, together with five motivational aspects of waste practices in urban, suburban, and rural areas. The analysis further considers how the motivational aspects are interlinked with practices within citizens’ perceived systems. In addition to the novel thematic contribution to the field, the findings can be used as a foundation to inform strategies to communicate with selected target audiences about their local challenges for sustainable waste management practices, in an attempt to influence citizen behaviours.
Shop Floor Digital Twin in Smart Manufacturing: A Systematic Literature Review
Authors: Corallo Angelo , Del Vecchio Vito Del , Lezzi Marianna , Morciano Paola
Published: December 2021

The digital twin is currently recognized as a key technology allowing the digital representation of a real-world system. In smart manufacturing, the digital twin enables the management and analysis of physical and digital processes, products, and people in order to foster the sustainability of their lifecycles. Although past research addressed this topic, fragmented studies, a lack of a holistic view, and a lack of in-depth knowledge about digital twin concepts and structures are still evident in the domain of the shop floor digital twin. Manufacturing companies need an integrated reference framework that fits the main components of both physical and digital space. On the basis of a systematic literature review, this research aims to investigate the characteristics of the digital twin for shop floor purposes in the context of smart manufacturing. The “hexadimensional shop floor digital twin” (HexaSFDT) is proposed as a comprehensive framework that integrates all the main components and describes their relationships. In this way, manufacturing organizations can rely on an inclusive framework for supporting their journey in understanding the shop floor digital twin from a methodological and technological viewpoint. Furthermore, the research strengthens the reference literature by collecting and integrating relevant contributions in a unique framework.
Comparing the Recommendations of Buyers of Energy-Efficient and Inefficient Vacuum Cleaners
Authors: Visser Mirjam , Stevels Ab , Schoormans Jan
Published: December 2021

Although environmental awareness is increasing every year, and most people say they prefer to buy more sustainable products, many still do not act on their promise at the cash counter. Sustainable products are often still perceived to have lower quality or reduced performance. Recommendations of sustainable buyers might reduce this perceived risk of sustainability. In this research, the Net-Promotor-Scores (NPS) and the underlying reasons for such recommendations of 888 vacuum cleaner buyers were analyzed. The buyers of energy-efficient vacuum cleaners were found to be significantly less positive about their purchase. A difference in scores is, however, not caused by the difference in the energy efficiency of the products, but by differences in other drivers to recommend a product, such as perceived cleaning performance, ease of use and value for money. Additionally, higher suction power and increased weight positively mediated NPS ratings, irrespective of energy efficiency. Focusing design and communication on these aspects rather than on energy efficiency alone can be used to reduce the perceived green risk and increase trust in sustainable products. In this way, recommendations of buyers of energy-efficient appliances can be an effective additional tool in increasing sustainable consumption.
Investigating Tourists’ Willingness to Walk (WTW) to Attractions within Scenic Areas: A Case Study of Tongli Ancient Town, China
Authors: Mao Yuanyuan , Ren Xiyuan , Yin Ling , Sun Qingying , Song Ke , Wang De
Published: December 2021

This paper aims to quantify tourists’ willingness to walk (WTW) in the intra-destination choice in pedestrian scenic areas. The case study presented is the Tongli Ancient Town (Jiangsu Province, China), which has a significant number of heritage sites, but tourism management has been weak. The main objective was achieved by surveying sequential destination choices in the site, with a total of 272 interviewed tourists. A Multi-Stop Behavior Model (MBM) was constructed to identify the factors that influence tourists’ intra-destination choice and willingness to walk (WTW). On the whole, the evidence showed that tourists prefer core-area attractions to peripheral attractions. Walking distance is the most important variable in tourists’ attraction choice. Moreover, WTWs of tourist segments showed both similarities and disparities, inspiring more pertinent strategies in line with tourists’ preferences. Policy and management implications are drawn based on the empirical findings and their effects are predicted using Monte Carlo (MC) simulation.

While the impacts of cigarette smoking on human health are widely known, a less recognized impact of tobacco product use and disposal is environmental pollution. This review discusses the current literature related to cigarette and e-cigarette contamination in the context of environmental sources and impacts, with a focus on the documented influences on biota, ranging from bacteria to mammals. Cigarette butts and electronic cigarette components can leach contaminants into soil, water, and air. Cellulose acetate cigarette filters comprising the butts are minimally degradable and are a source of bulk plastic and microplastic pollution, especially in aquatic ecosystems where they tend to accumulate. Cigarette combustion and aerosol production during e-cigarette use result in air contamination from sidestream, exhaled, and thirdhand pathways. The chemical byproducts of tobacco product use contaminate wastewater effluents, landfill leachates, and urban storm drains. The widespread detection of nicotine and cotinine in the environment illustrates the potential for large-scale environmental impacts of tobacco product waste. Studies show that cigarette butt leachate and nicotine are toxic to microbes, plants, benthic organisms, bivalves, zooplankton, fish, and mammals; however, there remain critical knowledge gaps related to the environmental impacts of tobacco product waste on environmental health and ecosystem functioning.
Elements of Social Sustainability among Austrian Hay Milk Farmers: Between Satisfaction and Stress
Authors: Scheurich Anja , Penicka Alexandra , Hörtenhuber Stefan , Lindenthal Thomas , Quendler Elisabeth , Zollitsch Werner
Published: December 2021

Proponents of hay milk farming claim several benefits on an ecological and economic level, while little about the social aspects has been studied so far. The present study serves as a first exploration of certain aspects of social sustainability from the perspective of hay milk farmers. The results of an online survey of 284 Austrian hay milk farmers are presented. The statistical analyses included Fisher’s exact tests (contingency tables), Kendall’s rank correlations and a two-step cluster analysis. The sampled farms show positive attitudes toward the work in agriculture (e.g., contribution to the cultural landscape) and are mainly satisfied regarding several job aspects (e.g., occupational diversity), but to a great extent dissatisfied with others (e.g., social recognition, time resources). The critical stressors are the agricultural policy, the economic situation, too little time for partnership or family life as well as bureaucracy and work overload. Multiple medium associations between aspects of well-being are revealed. Obvious and meaningful relationships between farm characteristics and aspects of well-being are scarce. The cluster analysis does little to help explain the characteristics of well-being within the patterns of farms. It therefore seems that the perception of the investigated aspects of well-being on hay milk farms is mostly formed individually and is only associated with the farms’ characteristics to a certain degree.

Published: December 2021

While there is a global consensus that agricultural systems need to be transformed to be more sustainable, possible pathways and challenges to this process are still debated. We analyse the challenges and opportunities involved in transforming smallholder farming to organic agriculture in Indonesia, where the intense application of Green Revolution technologies came at enormous environmental costs. We adopt a transdisciplinary approach to identify possible pathways towards organic agriculture, based on an analysis of farmers’ knowledge and barriers to adoption, value and belief systems, and institutional structures, including policies and regulations. We present our empirical findings as ‘system knowledge’, ‘target knowledge’ and ‘transformation knowledge’ and incorporate insights from both academics and practitioners. We draw on evidence from large-scale surveys, field experiments, in-depth interviews, participant observation and document analysis. A key insight of our research is that Indonesia does not lack initiatives towards organic farming, but that these various initiatives have different motivations, goals and strategies. This misalignment detracts from the transformational potential of organic agriculture and is responsible for the hitherto limited success of the organic transition. Our findings suggest that policy action at multiple levels is required, guided by an inclusive strategy that is drawn up in a participatory manner.

The path for bringing millions of people out of poverty in Africa is likely to coincide with important changes in land use and land cover (LULC). Envisioning the different possible pathways for agricultural, economic and social development, and their implications for changes in LULC, ecosystem services and society well-being, will improve policy-making. This paper presents a case that uses a multi-scale participatory scenario planning method to facilitate the understanding of the complex interactions between LULC change and the wellbeing of the rural population and their possible future evolution in Mozambique up to 2035. Key drivers of change were identified: the empowerment of civil society, the effective application of legislation and changes in rural technologies (e.g., information and communications technologies and renewable energy sources). Three scenarios were constructed: one characterized by the government promoting large investments; a second scenario characterized by the increase in local community power and public policies to promote small and medium enterprises; and a third, intermediate scenario. All three scenarios highlight qualitative large LULC changes, either driven by large companies or by small and medium scale farmers. The scenarios have different impact in wellbeing and equity, the first one implying a higher rural to urban area migration. The results also show that the effective application of the law can produce different results, from assuring large international investments to assuring the improvement of social services like education, health care and extension services. Successful application of these policies, both for biodiversity and ecosystem services protection, and for the social services needed to improve the well-being of the Mozambican rural population, will have to overcome significant barriers.

Published: December 2021

In the context of global climate change and urban expansion, extreme urban weather events occur frequently and cause significant social problems and economic losses. To study the climate risks associated with rapid urbanization in the global context of climate change, the vulnerability degree of urban agglomeration is constructed by the Grey Model (GM (1, 1)). Based on the sixth phase of the Coupled Model Intercomparison Project (CMIP6) data sets SSP1-2.6, SSP2-4.5, and SSP5-8.5, drought, heat wave, and flood hazards under different emission scenarios are calculated. The vulnerability degree of the urban agglomeration and the climate change hazard were input into the climate change risk assessment model to evaluate future climate change risk. The analysis results show regional differences, with the Beijing–Tianjin–Hebei urban agglomeration having good urban resilience, the Yangtze River Delta urban agglomeration having slightly higher overall risk, and the Pearl River Delta urban agglomeration having the highest relative risk overall. On the whole, the higher the emission intensity is, the greater the risk of climate change to each urban agglomeration under different emission scenarios.

Published: December 2021

Solid waste sorting facilities are constructed and operated to properly manage solid waste for both material and energy recovery. This paper investigates the possible technical and economic performance of the Al-Karak solid waste sorting plant in order to achieve financial sustainability and increase the profits that return on the plant to cover its operating costs. A standard procedure was followed to quantify and characterize the input materials of commercial solid waste by determining the recyclable materials in the sorting products. Thus, possible different equipment and material flows through the plant were proposed. An economic model was used in order to know the feasibility of the proposed options of the plant according to three economic factors, which are net present worth (NPW), return on investment (ROI), and payback period values. The results inferred that the characterization of the input materials contains a high portion of recyclable materials of paper, cardboard, plastic, and metals, which accounted for 63%. In this case, the mass of rejected waste to be landfilled was 9%. Results for the proposed options showed that the economic analysis is feasible when working loads on three and two shifts with ROI values of 4.4 and 3.5 with a payback period of the initial cost in 2 and 3 years, respectively. Working load on one shift was not feasible, which resulted in an ROI value of less than 2 and a payback period larger than 5 years. This paper recommended operating the sorting plant at a higher input feed with a working load on three shifts daily to ensure a maximum profit and to reduce the amount of commercial solid waste prior to landfilling through the concept of sorting and recycling.
Sensor Deployment Strategy and Traffic Demand Estimation with Multisource Data
Authors: Chen Hui , Chu Zhaoming , Sun Chao
Published: December 2021

Since traffic origin-destination (OD) demand is a fundamental input parameter of urban road network planning and traffic management, multisource data are adopted to study methods of integrated sensor deployment and traffic demand estimation. A sensor deployment model is built to determine the optimal quantity and locations of sensors based on the principle of maximum link and route flow coverage information. Minimum variance weighted average technology is used to fuse the observed multisource data from the deployed sensors. Then, the bilevel maximum likelihood traffic demand estimation model is presented, where the upper-level model uses the method of maximum likelihood to estimate the traffic demand, and the lower-level model adopts the stochastic user equilibrium (SUE) to derive the route choice proportion. The sequential identification of sensors and iterative algorithms are designed to solve the sensor deployment and maximum likelihood traffic demand estimation models, respectively. Numerical examples demonstrate that the proposed sensor deployment model can be used to determine the optimal scheme of refitting sensors. The values estimated by the multisource data fusion-based traffic demand estimation model are close to the real traffic demands, and the iterative algorithm can achieve an accuracy of 10−3 in 20 s. This research has significantly promoted the effects of applying multisource data to traffic demand estimation problems.
Love Match, Marriage Distance, and Marriage Payment: Evidence from Rural China
Authors: Lyu Qijia , Zhang Linxiu
Published: December 2021

The excessive marriage payment indicated by brideprice/dowry imposes a huge family financial burden, especially on rural households. Although some determinants have been examined, the relationship between matching types of couples and marriage payment is rarely known. The goal of this study is to analyze this relationship and the role of marriage distance in it. We adopt Logit, Tobit, and SUR models with the database across 70 years in rural China from a nearly national representative sample. The results show that love-match couples are 10.7% and 10.3% less likely to pay brideprice and dowry than that of parental matchmaking, respectively, and they pay less amount of brideprice and dowry. There is an inverted U-shaped relationship between marriage distance and brideprice/dowry, and love match has the largest correlation with marriage payment behaviors for couples with long marriage distance.
Spatial Differentiation of Non-Grain Production on Cultivated Land and Its Driving Factors in Coastal China

Published: December 2021

The rapid development of urbanization and industrialization in coastal China in the past 20 years has exerted a huge squeezing effect on agricultural land use. The phenomenon of non-grain production on cultivated land (NGP) is very common, seriously threatening the protection of high-quality arable land and national food security. In order to find out the overall situation regarding NGP on cultivated land in coastal China, this study revealed the spatial differentiation of NGP and its main driving factors by spatial autocorrelation analysis, multiple linear regression models and geographically weighted regression analysis (GWR). The results show that: (1) in 2018, the non-grain cultivated land area of 11 provinces along the coast of China was about 15.82 × 106 hm2, accounting for 33.65% of the total cultivated land area. (2) The NGP rate in 11 provinces gradually decreased from south to north, but the NGP area showed two peak centers in Guangxi province and Shandong province, then decreased gradually outwards. (3) The low economic benefit of the planting industry (per capita GDP and urban-to-rural disposable income ratio) was the most important driving force, leading to the spatial differentiation of NGP, while the number of rural laborers and land transfer areas also acted as the main driving factors for the spatial differentiation of NGP. However, the influence of each driving factor has obvious spatial heterogeneity. The non-grained area and the non-grain production rate at the municipal level were completely different from those at the provincial level, and the spatial heterogeneity was more prominent. In the future, the local government should control the disorganized spread of NGP, scientifically set the bottom line of NGP, reduce the external pressure of NGP, regulate multi-party land transfer behavior, and strengthen land-use responsibilities. This study can provide a scientific foundation for adjusting land-use planning and cultivated land protection policies in China and other developing countries.
Digitalization Capabilities for Sustainable Cyber Resilience: A Conceptual Framework
Authors: Annarelli Alessandro , Palombi Giulia
Published: December 2021

Digital transformation is currently an essential condition for companies to operate in most markets, since it provides a whole new set of competitive skills and strategic tools. On the other hand, the same digitalization puts companies in the face of a whole new series of threats coming from the cyber space. The foundation of business sustainability, which is the maintenance of competitiveness while securing business, is no longer a “plus” feature or a captivating sentence but a true and consistent need for all organizations. This article provides a literature analysis on approaches and models for cyber resilience, digitalization capabilities, and a conceptual framework showing how digitalization capabilities drive cyber resilience. Digitalization capabilities are involved in the plan/prepare phase and in the adaptation phase of the cyber resilience process. In particular, online informational capabilities can drive both these phases. Other capabilities such as the employment of heterogeneous resources and the promotion of continuous learning drive the plan/prepare phase, while the scanning of the evolution of the digital environment and a timely reconfiguration of resources drive the adaptation phase.
The Potential for Future Shifts in Tree Species Distribution Provided by Dispersal and Ecological Niches: A Comparison between Beech and Oak in Europe
Authors: Axer Maximilian , Schlicht Robert , Kronenberg Rico , Wagner Sven
Published: December 2021

(1) Due to global warming, distribution ranges of temperate tree species are shifting northwards and upslope to cooler areas. Shifts in distribution first become visible through changes in regeneration dynamics. However, the future distribution of tree species in the face of rapid climate change depends not only on the climatic suitability of the tree species, but also on its ability to disperse into new habitats. The aim of the study was therefore to examine how the distribution of European beech and European oak shifts and how species can spread from fragmented seed trees. (2) In order to investigate the shift in distribution of beech and oak, the bioclimatic envelopes of the old trees and different size classes of the natural regeneration were compared. Subsequently, a simulation of the potential distribution for the present climate, as well as for the climate for the reference period 2091–2100, for three different representative concentration pathways (RCP) scenarios was determined. In order to determine which of these areas can actually be colonised, a dispersal potential for the species was determined using a quantile regression, taking habitat fragmentation into account. (3) The results of the present study demonstrate range shifts of the tree species regeneration distribution (B0, B1 and B2) compared to the overstorey distribution (OST). While oak regeneration shows an expansion of its distribution in the cold-wet range, beech regeneration shows a reduction of its distribution in the dry-warm range. As the dispersal potential of oak exceeds that of beech, it is expected that oak will be better able to spread from fragmented seed trees. However, the results also indicate that many areas, despite climatic suitability, cannot be colonised due to too large dispersal distances. (4) For the forest management, this results in an important planning tool for future tree species composition, as climatic suitability, habitat connectivity and dispersal ability are taken into account.

The wine sector is one of the most ‘amazing’ and significant agri-food sectors worldwide since ancient times, considering revenue or employment as well as health aspects. This article aims to describe the impact of the implementation of blockchain technology (BCT) in the wine supply chain. After the literature review, the study is based on Agent Based Models (ABMs) and carried out by the GAMA program. Then, the model and simulation of BCT wine supply chain is designed. Finally, the paper compares traditional and BCT-based supply chains, and the advantages of the last one are evident. Blockchain is a useful tool to ensure a traceability system and to protect the production from any type of fraud and contamination.
Continuous Negotiation in Climate Adaptation: The Challenge of Co-Evolution for the Capability Approach to Justice
Authors: Brackel Lieke
Published: December 2021

The capability approach is increasingly presented as a promising approach to address questions of justice in local climate adaptation. In an attempt to integrate environmental protections into the capability approach, Breena Holland developed the meta-capability Sustainable Ecological Capacity to establish substantive ecological limits. This article, however, empirically demonstrates that defining ecosystem thresholds in co-evolving systems is subject to conflict and continuous negotiation. Taking the Haringvliet dam in the Dutch South-West Delta as an illustrative case, this paper shows how people uphold different views about the Haringvliet’s most desirable ecosystem state. Future shifts in the socio-ecological system, such as decreased fresh water availability and sea-level rise, are expected to uproot today’s compromise about chloride levels in the Haringvliet. This suggests that anticipatory water management should not only address climate impacts, but also prepare for re-negotiations of established ecological thresholds. The associated politics of climate adaptation deals with questions about which functions to protect, at what costs and for whom. Hence, it is critical to integrate procedural justice and attention to political inequalities in capabilities-based adaptation justice frameworks.

With the increasingly serious aging problem, getting around in communities has become an important means of socializing for older adults. This study proposes a new community aging-friendly transportation service system from the perspective of service design, so as to help realize the sustainable development of community services. To achieve this objective, the pain points and demands of older adults while traveling in communities were collected through a questionnaire survey, focus group interview, and user journey map. In addition, the grounded theory was applied to encode the qualitative data obtained in the focus group interview, so as to explore the path composition and dimension connotation of designing community transportation services. Based on the research results, we found that service strategy, service foundation, service support, and service effect are the key factors influencing customized transportation services. The established model covers the design framework of the service system, customized traffic service process, design strategy of community stakeholders, and traffic service system diagram. These research results provide references for community managers, community service providers, and designers.

Endophytes and rhizospheric microorganisms support invasive species’ adaptation to environmental stresses. Here, we review the impacts of endophytes, rhizospheric microbes (particularly symbiotic nitrogen-fixers), mycorrhiza and pathogens on plant invasion in arid and semi-arid areas. Endophytes and soil microorganisms either enhance nutrient acquisition for enhancing the invasive plant immune system and/or negatively affect native plants. In addition, the positive feedback between mycorrhizal fungi and invasive plants enhances the competitive ability of the aliens, providing them more opportunities for success, establishment, and dominance. The microbes and their secondary metabolites promote invasive plant species by changing soil microbial community structure and carbon biomass as well as enzyme activity, which improves soil properties and processes. The negative impact of invasive exotic plants on the associated biota and the role of allelochemicals are also discussed. It could be concluded that endophytes interact with rhizosphere microbes to promote invasive plant species in arid and semi-arid areas in a way similar to what happens in other ecosystems; the differences are in the pathways and reactions, which depend upon the prevailing abiotic factors. More interdisciplinary field experiments integrating microbial, biotechnological, and molecular approaches are needed to understand the role of symbiotic microbes in invasion biology.

Modification of a cell’s architecture can enhance the performance parameters. This paper reports on the numerical modeling of a thin-film organic solar cell (OSC) featuring distributed Bragg reflector (DBR) pairs. The utilization of DBR pairs via the proposed method was found to be beneficial in terms of increasing the performance parameters. The extracted results showed that using DBR pairs helps capture the reflected light back into the active region by improving the photovoltaic parameters as compared to the structure without DBR pairs. Moreover, implementing three DBR pairs resulted in the best enhancement gain of 1.076% in power conversion efficiency. The measured results under a global AM of 1.5G were as follows: open circuit voltage (Voc) = 0.839 V; short circuit current density (Jsc) = 10.98 mA/cm2; fill factor (FF) = 78.39%; efficiency (η) = 11.02%. In addition, a thermal stability analysis of the proposed design was performed and we observed that high temperature resulted in a decrease in η from 11.02 to 10.70%. Our demonstrated design may provide a pathway for the practical application of OSCs.
