The purpose of this paper is to develop a statistical-based model to forecast future domestic water demand in the context of climate change, population growth and technological development in Yellow River.

The model is developed through the analysis of the effects of climate variables and population on domestic water use in eight sub-basins of the Yellow River. The model is then used to forecast water demand under different environment change scenarios.

The model projected an increase in domestic water demand in the Yellow River basin in the range of 67.85 × 10⁸ to 62.20 × 10⁸ m³ in year 2020 and between 73.32 × 10⁸ and 89.27 × 10⁸ m³ in year 2030. The general circulation model Beijing Normal University-Earth System Model (BNU-ESM) predicted the highest increase in water demand in both 2020 and 2030, while Centre National de Recherches Meteorologiques Climate Model v.5 (CNRM-CM5) and Model for Interdisciplinary Research on Climate- Earth System (MIROC-ESM) projected the lowest increase in demand in 2020 and 2030, respectively. The fastest growth in water demand is found in the region where water demand is already very high, which may cause serious water shortage and conflicts among water users.

The simple regression-based domestic water demand model proposed in the study can be used for rapid evaluation of possible changes in domestic water demand due to environmental changes to aid in adaptation and mitigation planning.

PM10 is one of the most dangerous air pollutants which is harmful to the ecological system and human health. Accurate forecasting of PM10 concentration makes it easier for the government to make efficient decisions and policies. However, the PM10 concentration, particularly, the emerging short-term concentration has high uncertainties as it is often impacted by many factors and also time varying. Above all, a new methodology which can overcome such difficulties is needed.

The grey system theory is used to build the short-term PM10 forecasting model. The Euler polynomial is used as a driving term of the proposed grey model, and then the convolutional solution is applied to make the new model computationally feasible. The grey wolf optimizer is used to select the optimal nonlinear parameters of the proposed model.

The introduction of the Euler polynomial makes the new model more flexible and more general as it can yield several other conventional grey models under certain conditions. The new model presents significantly higher performance, is more accurate and also more stable, than the six existing grey models in three real-world cases and the case of short-term PM10 forecasting in Tianjin China.

With high performance in the real-world case in Tianjin China, the proposed model appears to have high potential to accurately forecast the PM10 concentration in big cities of China. Therefore, it can be considered as a decision-making support tool in the near future.

This is the first work introducing the Euler polynomial to the grey system models, and a more general formulation of existing grey models is also obtained. The modelling pattern used in this paper can be used as an example for building other similar nonlinear grey models. The practical example of short-term PM10 forecasting in Tianjin China is also presented for the first time.

This study investigates to what extent the values perceived by tourists throughout cultural tours impact their overall satisfaction levels and behavioral intentions related to the destination. This study further examines the moderating role of tour guide competency in the relationship patterns concerned.

Empirical data were collected via a survey from 420 foreign tourists who visited Cappadocia and participated in guided cultural tours. Partial least squares-structural equation modeling was used for data analysis.

Study results reveal that the effects of quality, emotional, monetary and social value perceptions of tourists gained through cultural tour experiences on their overall satisfaction levels and the effects of overall satisfaction on recommendation and revisit intention are positive and significant. Furthermore, the moderating role of tour guide competency is significant and positive in the relationships between quality value and satisfaction and between satisfaction and revisit intention.

This study offers a critical analysis of discoveries concerning the pivotal role of tour guide competency within the cultural tour experience.

The aim of this paper is to examine how the co‐evolution of two order systems‐guanxi networks and legal system, i.e. a dual order system‐has shaped the growth of China's SMEs. From an institutional perspective, one proposition suggested has been that building guanxi networks can facilitate the growth of China's SMEs when institutions change in unpredictable ways. Another proposition claims legal institutions become guarantors of the growth of China's SMEs as a result of competition in increasingly market‐oriented environment.

Over a nine‐year period (1998‐2006), this study conducts in‐depth interviews with 18 top managers of three Chinese SMEs in Wenzhou, a city located in south of China. To identify potential research subjects, SMEs that had been operating for a period of at least five years and privately‐owned were chosen. Since institution evolution is characterized with a longitudinal nature, the authors gathered data from three different time periods in order to capture the richness of the phenomenon.

Dual order mechanisms consisting of guanxi networks (informal institutions) and codified laws (formal institutions) are both relevant in the growth of SMEs: guanxi networks are more significant at earlier stages of growth whereas legal systems are more influential in later stages. This argument is supported with data collected from three longitudinal case studies of SMEs in China.

Data were obtained from three companies in Wenzhou of China, thus findings might not be generalizable across the country.

Three longitudinal case studies are unique. According to Pettigrew, longitudinal methods may be the only way to uncover processes of institutional change. The paper investigates the role of dual order system consisting of guanxi and legal systems in the growth of China's SMEs. The research not only contributes to the guanxi literature but also enables managers and investors to better understand the guanxi practice and role of legal systems in the growth of SMEs.

Based on the aerodynamic loads and dynamic performances of trains, this study aims to investigate the effect of crosswinds and raindrops on intercity trains operating on viaducts to ensure the safe operation of intercity railways in metropolitan areas.

An approach coupled with the Euler multiphase model as well as the standard k-ɛ turbulence model is used to investigate the coupled flow feature surrounding trains and viaducts, including airflow and raindrops, and the numerical results are validated with those of the wind tunnel test. Additionally, the train’s dynamic response and the operating safety region in different crosswind speeds and rainfall is investigated based on train’s aerodynamic loads and the train wheel–rail dynamics simulation.

The aerodynamic loads of trains at varying running speeds exhibit an increasing trend as the increase of wind speed and rainfall intensity. The motion of raindrop particles demonstrates a significant similarity with the airflow in wind and rain environments, as a result of the dominance of airflow and the supplementary impacts of droplets. As the train’s operating speed ranged between 120 and 200 km/h and within a rainfall range of 20–100 mm/h, the safe operating region of trains decreased by 0.56%–7.03%, compared with the no-rain condition (0 mm/h).

The impact of crosswind speeds and rainfall on the train’s aerodynamic safety is studied, including the flow feature of crosswind and different particle-sized raindrops around the train and viaduct, aerodynamic loads coefficients suffered by the intercity train as well as the operating safety region of intercity trains on the viaduct.

By integrating stimulus-organism-response theory and uses and gratifications theory, this study explored the salient gamification factors that satisfy the gratifications of conference attendees in the context of an event gamification mobile app and their relationships with conference engagement, continuance intention and word-of-mouth.

The questionnaire was developed in Qualtrics and administered on a gamification application called Goosechase during an annual hospitality conference. The proposed hypotheses were tested using the partial least square-structural equation modeling (PLS-SEM).

The gratifications of social presence, education and entertainment through a gamification mobile app influences attendees’ engagement during the conference while achievement gratification does not. Positive effects of conference engagement on their continuous intention and WOM have been also validated.

By adopting a unique integrated approach that utilizes UGT and S-O-R framework, while considering conference engagement as work-related engagement, this study offers a fresh perspective on gamification apps and discusses its theoretical and practical implications in depth.

Marketing theory and practice is under severe criticism – socialists and the practitioners criticize marketing in its current form which calls for active efforts by marketers to reposition the discipline – making it beneficial to the masses. The Western world is thoroughly investigated based on the opinions of public regarding marketing as a discipline. However, studies which present a non-Western consumer’s attitudes toward the role of marketing in a society are scant. This purpose of this study is to encapsulate Pakistani consumers’ understandings and attitudes toward marketing with an emphasis on their perceptions of the ethicality and transformative power of the discipline.

A purposive convenience sample of 40 professionals with diverse non-marketing backgrounds and of the widest possible demographic profile participated in in-depth, unstructured interviews. The content analysis and grounded theory method were used for the analysis.

Marketing is appreciated for creating product awareness and, occasionally, combating social problems, but this positive image is clouded by severely criticizing it for promoting materialism, being irritatingly pervasive and pushy, as well as for using unethical and unfair practices.

The study offers a valuable insight into the discipline’s performative and social legitimation in a fast-growing Asian economy. The authors recommend paths for a positive repositioning of the discipline that will improve its public image and enhance its potential for being recognized as a force for positive social change.

Further to enhancing our understanding of consumer attitudes toward marketing, this paper’s value lies in it being the first ever exploration of the developing country perspective. Most importantly, it contributes to a debate that could enlighten the much-needed repositioning of marketing as a discipline to make it useful for masses.

Since 2017, China's digital economy has accounted for more than 30% of the country's GDP. The digital economy has become the main driving force of China's economic development. Moreover, the digital economy has also changed the traditional modes of production and distribution between urban and rural areas. This paper aims to explore the influential mechanism of digital economy infrastructure (DEI) on the urban-rural income gap (URIG).

By analyzing the theoretical model of the URIG, this paper constructs a theoretical analysis framework and clarifies the key roles of rural land circulation (RLC) and resident population urbanization (RPU) in the relationship between DEI and the URIG.

The DEI can effectively reduce the URIG; the regression coefficient (RC) was −0.109. The reduction effect is mainly reflected in: 1) the wage income gap between urban and rural residents (RC = −0.128) and 2) the net property income gap of urban and rural residents (RC = −0.321). Also, for the spatial spillover effect, the path effect of “DEI – RLC – URIG” is almost equal to the path effect of “DEI – RPU – URIG”; for the local effect, the path effect of the former is far smaller than the latter. Moreover, when the RPU reaches the threshold of 86.29%, the DEI will expand the URIG (RC = 0.201).

This paper proposes a theoretical framework for the impact of DEI on the URIG, explores the mechanism of RLC and RPU in the DEI and URIG and enriches the theory of traditional research on URIG.

The physiological and psychological issues that limit people with vision impairment make it difficult for them to participate in tourism activities and enjoy the various benefits of tourism. This study aims to construct a theoretical model of the tourism-influencing factors that can lead to problems for people with vision impairment to meet their travel desires and improve their enjoyment of life.

This study adopted a mixed-methods approach. A theoretical model of the tourism-influencing factors for people with vision impairment was constructed based on grounded theoretical analysis of interviews and was then tested in a quantitative survey.

In the first stage, a new theoretical model of the tourism-influencing factors for people with vision impairment was conducted. In the second stage, five research hypotheses arising from the theoretical model were tested in a quantitative survey. The results show that internal psychological perception, perceived behavioural control and perceived social intention have a significant positive impact on the tourism intention behaviour of people with vision impairment. However, subjective norms do not significantly influence the tourism behaviour intention of people with vision impairment.

The right to tourism should be available to disabled as well as to able-bodied people. Few tourism research studies have focused on people with vision impairment, and the influencing factors on the behaviour of people with vision impairment have not received due attention. This study extends the theoretical model of the theory of planned behaviour and provides a new perspective for understanding the travel behaviour intention of people with vision impairment.

La limitación de los problemas físicos y psicológicos de las personas con discapacidad visual, dificulta su participación en actividades turísticas y el disfrute de los beneficios del turismo. El objetivo de este estudio es construir un modelo teórico de los factores que influyen en el turismo y que puedan causar problemas a las personas con discapacidad visual para satisfacer sus deseos turísticos y mejorar su disfrute de la vida.

En este estudio se utilizó un método mixto. Sobre la base del análisis de la teoría de la raíz de la entrevista, se construye el modelo teórico de los factores que influyen en el turismo de las personas con discapacidad visual.

En la primera etapa, se establece un nuevo modelo teórico sobre los factores que influyen en el turismo de las personas con discapacidad visual. En la segunda etapa, se investigan cuantitativamente las cinco hipótesis de investigación presentadas por el modelo teórico. Los resultados mostraron que la percepción psicológica interna, el control del comportamiento percibido y la intención social percibida tenían un efecto positivo significativo en el comportamiento de la intención turística de los pacientes con discapacidad visual. Sin embargo, las normas subjetivas no tienen un efecto significativo en la intención de comportamiento turístico de las personas con discapacidad visual.

Las personas con discapacidad y las personas sanas tienen derecho al turismo. Pocas investigaciones turísticas se centran en las personas con discapacidad visual, y no se presta la debida atención a los factores que influyen en el comportamiento de las personas con discapacidad visual. Este estudio amplió el modelo teórico de la teoría del comportamiento planificado y proporcionó una nueva perspectiva para entender la intención de comportamiento de viaje de las personas con discapacidad visual.

Work in distributed project teams is always a challenge for organizations. Many researchers have studies different aspects of distributed project teams, as witnessed by the impressive number of papers published in the last decade. However, it appears that the dimensions related to organizational support have still not received much attention in empirical studies. This study investigates the dimensions of organizational support in distributed project teams that contribute most to the quality of the decision‐making process and teamwork effectiveness in distributed project teams.

The initial intent of this research was to test a theoretical model on the basis of data from the field, namely real‐life situations. A two‐step approach (qualitative and quantitative method) was used. The research model was tested in a sample of experienced project managers on distributed project teams.

The results suggest that strategic staffing and training and tools provided to team members have a positive impact on the quality of decision making and teamwork effectiveness. Team autonomy is more salient and influential in fostering decision quality in a highly culturally diverse context. Our findings also re‐confirm the link between the quality of decision making and team effectiveness. Thus, teams are perceived as vehicles for identifying and integrating various individual viewpoints and combining knowledge.

This study underscores the importance of selecting practices that enhance the recognition of team members’ contributions in the context of distributed project teams. It is now clear that managers cannot treat these distributed project teams in the same way as conventional teams. Several intervention and support methods are possible. This research contributes to identifying which of them are the most appropriate in this context.

This study contributes to research on distributed project teams and on organizational support theory. It highlights the importance of understanding the processes or dimensions underlying the consequences of perceived organizational support. It bolsters the need to select practices that enhance the recognition of team members’ contributions and treat them favourably in the context of distributed project teams.
