To support urban sustainable development, cities need innovative green logistics solutions to meet the needs of economic development. Crowdshipping is regarded as a promising sustainable freight solution. This article aims to assess the feasibility of implementing intercity express crowdshipping using private vehicle traveling. The crowdshipping carrier, who drives his or her private vehicle and travels on the intercity route, carries out the express delivery task between the regional cargo center and the dispatch center along the route. The feasibility assessment covers three parts. First, face-to-face interview and stated preference survey are used to investigate the willingness and preferences of express companies and car owners to participate in crowdshipping activities, respectively. Then, it calculates the environmental benefit and economic benefit brought by the crowdshipping mode in comparison with the traditional mode. The results show that the express companies are willing to pay 30 yuan for each car participating in the crowdshipping activities, and there are considerable numbers of car owners to support this crowdshipping activity, and this crowdshipping activity could bring positive impacts on environment as well as corporate economics. It is hoped that the research could enrich the knowledge of the development of green logistics.

Before And After

Studies on the adaptation from face-to-face to online teaching during lockdown show the before and after in education that faces the double challenge of promoting digital skills and public access to connectivity and electronic devices in the post-COVID-19 era. Therefore, this article contributes to these new emerging lines of educational research by presenting an educational innovation project called “Teachers Versus COVID-19”. This project aimed to verify whether the figure of teacher-prosumer, that is, consumers of media culture and creators of their own educational resources, favors the initial training of teachers during the pandemic. To this end, the following objectives were proposed: firstly, test whether the figure of the teacher-prosumer contributes to improving the adaptation of face-to-face teaching to the virtual modality of the Didactics of Social Sciences in the Degree in Primary Education during lockdown; secondly, analyze the production of content on social networks by the students in the Degree in Primary Education, according to the objectives of sustainable development. To validate our teacher-prosumer proposal, we chose the design-based research (DBR) qualitative methodology. For this, 240 students from the course in Didactics of Social Sciences of the Degree in Primary Education at the University of Malaga created 37 educational videos that teach the social sciences curriculum to children between 6 and 12 years of age from the perspective of relevant social problems and the Sustainable Development Goals. These videos were disseminated through the project’s YouTube channel. The results of this study corroborate the effectiveness of turning students into teachers-prosumers, generating the development of critical, creative, digital, and socio-emotional skills so that they feel committed to playing an active role in social changes for a sustainable world.

The contradiction between the effective supply and the uncertain demand in housing security system, which is an important part of the urban social security system, has been a major obstacle to urban sustainable development since 1998, and how to effectively deal with it is becoming more and more important. In this paper, the uncertain demand of indemnificatory housing, which was caused by the rapid urbanization, is considered, and the models for indemnificatory housing provision under box constraints, ellipsoid constraints and polyhedral constraints are constructed respectively by using distributional robust optimization, and at the same time, the reliability of optimal models in theory is proved in the form of theorem. In the end, as application of models, the paper takes Beijing as an example, and conducts empirical research on provision of indemnificatory housing during the past five years (2006-2010), which shows the effectiveness of the method.

Considerando que o processo de desenvolvimento urbano implica na multiplicação dos impactos ambientais decorrentes do assentamento humano sobre a área de influência da cidade e a existência de diretrizes de ação visando à promoção da sustentabilidade urbana na Agenda 21 brasileira, bem como nas disposições do Estatuto da Cidade, especialmente no que se refere aos objetivos da política urbana, garantia do direito a cidades sustentáveis, planejamento do desenvolvimento urbano, estudo de impacto de vizinhança e ao Plano Diretor, o trabalho aponta possibilidades de efetivação destas diretrizes e dispositivos legais no gerenciamento urbano por meio de políticas públicas locais no âmbito dos transportes, habitação e uso do solo. Tais políticas deverão estar dirigidas a objetivos ambientais definidos em função do grau de qualidade ambiental urbana presente e da eqüidade da sua distribuição espacial, visando a uma situação futura desejada. Public policies and urban sustainable development Abstract Considering that urban development is directly related to the spreading of environmental impacts caused by human settlements within city limits and the existence of directives in the Brazilian Agenda 21 regarding the promotion of urban sustainability, as well as the content of the City Statute regarding urban policies towards sustainable cities and urban planing, this study presents possibilities of implementing directives and legal measures for urban management by means of local public policies concerning transportation, habitation and land use. Such policies should be directed towards environmental objectives, defined with regard to the present urban environmental quality and spatial distribution, aiming at a desired future condition.

Harmful Effects

Reducing the harmful effects on the environment and increasing the expression of sustainable development principles is one of the most topical challenges all around the world. Given the importance of logistics for the economy and the growing concern for the environment, the purpose of this article was to reveal a green logistics (GL) practice framework for sustainable development. Based on a systematic and comparative analysis of the scientific literature, the authors present a theoretical conceptual model for applying GL practices to sustainable development. In order to assess the expression of GL practices and their determinants in Lithuanian transport and logistics services companies, a quantitative questionnaire survey was conducted. Descriptive statistics, correlation, and regression analyses were used to analyze the data. The results made it possible to identify GL areas such as green transportation, green warehousing, green management, sustainable waste management, and the prevailing GL practices in Lithuania: “Eco-driving”, “Optimization of transport routes”, and “Optimization of transport cargo distribution”. The factors that most encouraged the application of GL practices in the studied companies were: legal regulation and policies, requirements of business partners, service users, customers and society, awareness of the company’s top management, and corporate culture focused on environmental conservation and sustainable development.

With the rapid urbanization in recent decades, resource shortage and environmental damage have hindered the process of urban sustainable development (SD). As a yardstick of sustainable development, the evaluation of resources and environment carrying capacity (RECC) and its decoupling relationship with social comprehensive development index (SCDI) are of great significance. In this paper, RECC and SCDI are taken as research objects to establish resource and environment system evaluation index system and social comprehensive development level evaluation index system, respectively. Then, the RECC and SCDI of 17 cities in Hubei province during 2009–2018 are calculated by the projection pursuit model based on genetic algorithm, and their spatial-temporal variance characteristics are analyzed. On this basis, the RECC-SCDI Tapio decoupling model is constructed to explore the decoupling relationship between RECC and SCDI. The result shows that: (1) The RECC of Hubei shows a V-shaped development trend during 2009–2018. The SCDI of Hubei rose steadily during 2009–2018. (2) RECC in western and eastern Hubei Province is higher than that in central Hubei Province. SCDI in eastern and central Hubei Province is higher than that in the west. (3) 11 of the 17 cities in Hubei Province have got rid of excessive dependence on resources environment for social development. The study could contribute to scientific and effective policies be formulated by government to promote urban sustainable development.
