The current study explored the triadic relationship between the government, local residents and developers as stakeholders in rural tourism land expropriation. Unstructured interviews and non-participant observation were conducted to obtain relevant data. Social action theory was applied to delineate the complex interaction and relationships between the various stakeholders. Growth machine theory was also used to reveal the internal mechanisms of these relationships. The results showed that in land expropriation for rural tourism development in the case setting, stakeholders' relationships were not merely cooperative or antagonistic; rather, their interests were interwoven and showed a process-based evolution with the progress of land expropriation. Finally, the local government (political elite) and the developer (economic elite) formed a growth coalition and jointly led the process of land expropriation. However, local residents failed to form an anti-growth coalition, which indicates the potential vulnerability of tourism coalition formation. These insights have implications for developing sustainable tourism, including government involvement and resident participation, particularly in the context of developing countries.

Social capital plays an essential role in the early stage of rural tourism development. Taking the family as the research unit, this study applied social capital theory to examine how guanxi serves residents' interests in negotiations during housing demolition. Nonparticipant observations and in-depth interviews were conducted to identify the utility and essence of guanxi during housing demolition for rural tourism development in a Chinese village. The results show that guanxi, as a kind of social capital, plays an important role in rural tourism development, and that the internal mechanism through which guanxi exerts its utility is 'guanxi - power - interest.' The study offers important theoretical and practical implications for both governments and tourism developers which benefits the destination management

The North China Plain (NCP) is one of the major agricultural regions in China. Winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.) are currently the two main crops combined in a single-year rotation also referred to as a double cropping system. Grain production in the NCP has experienced multiple changes over the last decades due to many factors including shortages in water resources, government policy, etc. This paper analyzes the changes in yield performance of wheat and maize during 1984-2003. Results showed that in general a more intensive use of productive inputs seemed to be associated with higher yields. Further results clearly indicated that water shortage is currently the main problem in the traditional double cropping system and can endanger the desired self-sufficiency of China in the future. Therefore future profound policy changes may make the question of yield performance as important as the questions to adopt new crops or new cropping systems. This study suggests tat changes from the traditional double cropping system to single spring maize cultivation might solve parts of the water shortage problems while maintaining at the same time high yields. ; Die Nordchinesische Tiefebene (NCP) ist eines der wichtigsten Agrarregionen in China. Winterweizen (Triticum aestivum L.) und Sommermais (Zea mays L.) sind gegenwärtig die zwei Hauptfrüchte und werden in einer einjährigen Rotation kombiniert, die auch als Winterweizen- Sommermais Double-Cropping System bezeichnet wird. Die Getreideproduktion in der NCP hat sich in den letzten Jahrzehnten unter dem Einfluss vieler Faktoren wie beispielsweise Wasserknappheit, politischen Regelungen usw. zunehmend verändert. Im vorliegenden Artikel wurden die Änderungen in der Ertragsleistung von Weizen und Mais während der Jahre 1984-2003 untersucht. Im allgemeinem betrachtet, zeigten die Ergebnisse, dass durch den intensiven Einsatz von Produktionsfaktoren die Erträge anstiegen. Weiterhin wurde deutlich, dass die Verknappung von Wasser gegenwärtig das ...

Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have been developed by experts in a project co-financed by the European Union. The 450-page guidelines were published in book format by the European Commission in 2010.They include 10 chapters and over 250 recommendations, individually graded according to the strength of the recommendation and the supporting evidence. Adoption of the recommendations can improve and maintain the quality and effectiveness of an entire screening process, including identification and invitation of the target population, diagnosis and management of the disease and appropriate surveillance in people with detected lesions. To make the principles, recommendations and standards in the guidelines known to a wider professional and scientific community and to facilitate their use in the scientific literature, the original content is presented in journal format in an open-access Supplement of Endoscopy. The editors have prepared the present overview to inform readers of the comprehensive scope and content of the guidelines.

The Transiting Exoplanet Survey Satellite, TESS, is currently carrying out an all-sky search for small planets transiting bright stars. In the first year of the TESS survey, a steady progress was made in achieving the mission's primary science goal of establishing bulk densities for 50 planets smaller than Neptune. During that year, the TESS's observations were focused on the southern ecliptic hemisphere, resulting in the discovery of three mini-Neptunes orbiting the star TOI-125, a V = 11.0 K0 dwarf. We present intensive HARPS radial velocity observations, yielding precise mass measurements for TOI-125b, TOI-125c, and TOI-125d. TOI-125b has an orbital period of 4.65 d, a radius of 2.726 ± 0.075 RE, a mass of 9.50 ± 0.88 ME, and is near the 2:1 mean motion resonance with TOI-125c at 9.15 d. TOI-125c has a similar radius of 2.759 ± 0.10 RE and a mass of 6.63 ± 0.99 ME, being the puffiest of the three planets. TOI-125d has an orbital period of 19.98 d and a radius of 2.93 ± 0.17 RE and mass 13.6 ± 1.2 ME. For TOI-125b and d, we find unusual high eccentricities of 0.19 ± 0.04 and 0.17^{+0.08}_{-0.06}, respectively. Our analysis also provides upper mass limits for the two low-SNR planet candidates in the system; for TOI-125.04 (RP = 1.36 RE, P = 0.53 d), we find a 2¿ upper mass limit of 1.6 ME, whereas TOI-125.05 (R_P=4.2^{+2.4}_{-1.4} RE, P = 13.28 d) is unlikely a viable planet candidate with an upper mass limit of 2.7 ME. We discuss the internal structure of the three confirmed planets, as well as dynamical stability and system architecture for this intriguing exoplanet system. ; With funding from the Spanish government through the "María de Maeztu Unit of Excellence" accreditation (MDM-2017-0737)
