Strategy for rural heritage regeneration in China : integrating community and government in governance: a case study of traditional villages in Luoning county :
Wendi Wang, 2024, doktorska disertacija

Opis: The Chinese countryside has long been associated with cultural continuity, albeit in contradictory ways. It has been marginalized for several decades, while all development efforts have focused on urbanization. However, as the tensions and paradoxes of modern urban life become increasingly obvious, the countryside is once again recognized as an enduring symbol of authentic national values. Chinese traditional cultural heritage is rooted in Chinese traditional villages. In fact, being built before the coming of the Republic of China, those villages nowadays still possess a great deal of very important material and immaterial forms of cultural heritage, as a historical record of the Chinese nation development. Through the examination and study of traditional villages in Luoning, and the perspective of theories of architectural conservation theory, community co-construction, and private-public partnership, the dissertation proposes a hybrid county governance model to maximize the stakeholder's functions roles, and operational procedures in the preservation and development of the traditional villages. Thus, through the integration of three stability perspectives—cultural, economic, and social —the dissertation provides the government's optimization strategy for heritage preservation. In the first case study, the governance of Zhangzhuang's traditional village is examined. The village's residents share responsibility for one another and are frequently connected by strong family ties and regular community organization in decision-making. Unfortunately, this thriving community-led government is insufficiently prepared to deal with the expanding tourism industry, it fails when it comes to overarching development objectives, and it lacks substantial experience in the preservation of historic structures. The Second case study investigates the government-led traditional types of villages. These are characterized by low public and community participation, and underdeveloped commodity economies, but being usually of outstanding importance, they result rich in traditional material and intangible cultural resources and have great potential for developing a tourism sector. Government-led efforts to reactivate the development of these villages have the advantages of credibility and authority, preferential policy formulation, and government short-term funding. However, these villages face severe problems in terms of community involvement, complementary market economies, and insufficient long-term government funding. This condition is investigated in the second case of the government's conception and promotion of the "Hou Shangzhuang Village Traditional Village Restoration" project. Despite some initial success, the project came to a standstill due to the competing interests of businesses, the government, and the community. The third case study looks into traditional villages where the primary development component is driven by businesses, creating conditions for the growth of a market economy. The analysis demonstrates that enterprise investments benefit from complementary capital input, resource integration, and effective management. However, the issue of uneven income and benefit distribution, as well as excessive consumption of public resources, pose a serious threat to both: the authenticity and integrity of cultural heritage, as well as the fair and sustainable development of local communities. This situation is examined in the case study of Qianhe Village, where the tourism industry has grown through multiple investment operations by private enterprises. The dissertation examines diverse hybrid governance models for each of these three different cultural, social, and economic heritage contexts. In specific it points to the role of government to efficiently design, validate, and promote responsive solutions for the resilience of cultural heritage of traditional villages in China.

Performance analysis of high-spectral-resolution lidar with/without laser seeding technique for measuring aerosol optical properties
Fengjia Gao, Fei Gao, Gaipan Li, Fan Yang, Li Wang, Song Yuehui, Dengxin Hua, Samo Stanič, 2024, izvirni znanstveni članek

Opis: High-spectral-resolution lidar (HSRL) is a powerful tool for aerosol measurements. With/without laser seeding technique in the transmitted laser, the HSRL can be distinguished as the single-longitudinal-mode (SLM) HSRL or the multi-longitudinal-mode (MLM) HSRL, and the Mach-Zehnder interferometer (MZI) with periodic transmittance function can be used as the spectral discriminator in both the SLM HSRL and MLM HSRL. To in-depth knowledge of the respective advantages of the SLM HSRL and MLM HSRL for measuring aerosol optical properties, the working principle, optimal parameter setting, and detection performance of the SLM HSRL and MLM HSRL are analyzed and discussed in detail, respectively. The working principle of the SLM HSRL and MLM HSRL indicate that the effective transmittance of MZI is the important parameter of data retrieval, the main source of retrieval uncertainties, and the key factor of MZI optical path difference (OPD) settings. To ensure that the MZI can achieve the preferable separation for aerosol Mie scattering signals and molecular Rayleigh scattering signals, the optimal OPDs of MZI are set at 165 mm and 1000 mm in the SLM HSRL and MLM HSRL from the aspects of the effective transmittance of MZI and the spectral discrimination ratio (SDR). Besides, to analyze the influence of frequency difference and divergence angle for the detection performance of HSRL, the effective transmittance of MZI and SDR are simulated and the results show that the MLM HSRL has higher requirements for the environmental parameters and the echo beam collimation than the SLM HSRL. Moreover, the HSRLs with SLM and MLM transmitted lasers are constructed in Xi'an for measuring aerosol optical properties. The preliminary measurement results show that the range square corrected signal (RSCS) of Rayleigh channel is smaller than that of Mie channel in both the SLM HSRL and MLM HSRL, while the difference between RSCS of Rayleigh channel and RSCS of Mie channel in the SLM HSRL is larger than that in the MLM HSRL, and the detection range of the SLM HSRL is lower than that of the MLM HSRL.

Changes in exhaled volatile organic compounds following indirect bronchial challenge in suspected asthma
Adam Peel, Ran Wang, Waqar Ahmed, Iain R. White, Maxim Wilkinson, Yoon K. Loke, Andrew M. Wilson, Stephen J. Fowler, 2023, izvirni znanstveni članek

Opis: Background Inhaled mannitol provokes bronchoconstriction via mediators released during osmotic degranulation of inflammatory cells, and, hence represents a useful diagnostic test for asthma and model for acute attacks. We hypothesised that the mannitol challenge would trigger changes in exhaled volatile organic compounds (VOCs), generating both candidate biomarkers and novel insights into their origin. Methods Participants with a clinical diagnosis of asthma, or undergoing investigation for suspected asthma, were recruited. Inhaled mannitol challenges were performed, followed by a sham challenge after 2 weeks in participants with bronchial hyper-responsiveness (BHR). VOCs were collected before and after challenges and analysed using gas chromatography–mass spectrometry. Results Forty-six patients (mean (SD) age 52 (16) years) completed a mannitol challenge, of which 16 (35%) were positive, and 15 of these completed a sham challenge. Quantities of 16 of 51 identified VOCs changed following mannitol challenge (p<0.05), of which 11 contributed to a multivariate sparse partial least square discriminative analysis model, with a classification error rate of 13.8%. Five of these 16 VOCs also changed (p<0.05) in quantity following the sham challenge, along with four further VOCs. In patients with BHR to mannitol distinct postchallenge VOC signatures were observed compared with post-sham challenge. Conclusion Inhalation of mannitol was associated with changes in breath VOCs, and in people with BHR resulted in a distinct exhaled breath profile when compared with a sham challenge. These differentially expressed VOCs are likely associated with acute airway inflammation and/or bronchoconstriction and merit further investigation as potential biomarkers in asthma.

Investigation of the effective transmittance of Mach-Zehnder interferometer in the multi-longitudinal-mode high-spectral-resolution lidar
Fei Gao, Fengjia Gao, Xiao Yang, Gaipan Li, Li Wang, Meng Wang, Dengxin Hua, Griša Močnik, Samo Stanič, 2022, izvirni znanstveni članek

Opis: Effective transmittance is an important parameter of Mach-Zehnder interferometer in the retrieval of aerosol optical properties using the multi-longitudinal-mode high-spectral-resolution lidar, which is a function of the complex degree of coherence. In this paper, we retrieve the parameter of the complex degree of coherence for the multi-longitudinal-mode laser from the theoretical analysis, optical simulation and experimental measurements, which are 0.726, 0.678 and 0.453 using the Mach-Zehnder interferometer with the optimal optical path difference of two times of laser optical cavity length (∼1000 mm) and under the light illumination of the high power Nd:YAG laser with the mode number of 101 and mode interval of 300 MHz under the condition of laser linewidth of 1 cm−1 (30 GHz). The preliminary measurement results of aerosol optical properties using the constructing multi-longitudinal-mode high-spectral-resolution lidar show that the difference of the complex degree of coherence retrieved from the presented methods results in the relative error of 40% in the aerosol backscattering coefficient with thin cloud layer and 90% with the presence of dense aerosol layer.

Investigation of Aerosol Types and Vertical Distributions Using Polarization Raman Lidar over Vipava Valley
Longlong Wang, Marija Bervida, Samo Stanič, Klemen Bergant, Asta Gregorič, Luka Drinovec, Zhenping Yin, Yang Yi, Detlef Müller, Xuan Wang, 2022, izvirni znanstveni članek

Opis: Aerosol direct radiative forcing is strongly dependent on aerosol distributions and aerosol types. A detailed understanding of such information is still missing at the Alpine region, which currently undergoes amplified climate warming. Our goal was to study the vertical variability of aerosol types within and above the Vipava valley (45.87◦ N, 13.90◦ E, 125 m a.s.l.) to reveal the vertical impact of each particular aerosol type on this region, a representative complex terrain in the Alpine region which often suffers from air pollution in the wintertime. This investigation was performed using the entire dataset of a dual-wavelength polarization Raman lidar system, which covers 33 nights from September to December 2017. The lidar provides measurements from midnight to early morning (typically from 00:00 to 06:00 CET) to provide aerosol-type dependent properties, which include particle linear depolarization ratio, lidar ratio at 355 nm and the aerosol backscatter Ångström exponent between 355 nm and 1064 nm. These aerosol properties were compared with similar studies, and the aerosol types were identified by the measured aerosol optical properties. Primary anthropogenic aerosols within the valley are mainly emitted from two sources: individual domestic heating systems, which mostly use biomass fuel, and traffic emissions. Natural aerosols, such as mineral dust and sea salt, are mostly transported over large distances. A mixture of two or more aerosol types was generally found. The aerosol characterization and statistical properties of vertical aerosol distributions were performed up to 3 km.
