Industrial Upgrade, Adverse Employment Shock and Land Centralization
Traditional Development Economics defines economic development in the view of transferring rural surplus labor force. It implies the industrialization is in a static state at a certain level while it is in a process of continuous industrial upgrade in reality. Under the circumstances, we analyze phenomenon followed by the upgrading of industrial structure such as return migration and mid-aged rural labors’ difficulty in job-hunting and demonstrated the influence of land centralization based on the practice of industrial upgrade and rural change in Suzhou. Finally it come to the conclusion that because of the extensive competition on simple-labor market, the industrial upgrade will make a adverse employment shock upon mid-aged rural labor which will lead to the more uncertainty of peasants to get jobs in the industrial section . If government takes an improper policy of land centralization, peasants will lose guarantee in the future and resist the land centralization. After the comparison between one-off compensation and land cooperation, a further demonstration show that the method of one-off compensation will depress peasants’ enthusiasm in land centralization while the form of land cooperation can guarantee and promote peasants’ welfare under the given institution of land ownership. As a result, land cooperation allows the smooth operation of land centralization and supports the industrial upgrade to some extent.Over-confidence,Regional Government Competition,Redundant Construction,Yangzte River Delta
Industrial Upgrade, Employment Shock and Land Centralization in China
This paper investigates the relationships among industrial upgrading, mid-aged peasants’ non-farm employment, and land conversion systems. We prove that China’s efforts to upgrade its industries generate a negative employment shock on mid-aged peasant workers, forcing some of them to return to their home villages. The current lump-sum land acquisition system, however, will neither help peasant workers deal with the adverse employment shock nor promote land centralization for industrial and urban uses. On contrary, land cooperation, an emerging land centralization system, will help peasant workers mitigate the adverse employment shock and centralize rural land for nonagricultural purposes.Peasant workers; Industrial upgrade; Employment; Land centralization

CL-Flow:Strengthening the Normalizing Flows by Contrastive Learning for Better Anomaly Detection
In the anomaly detection field, the scarcity of anomalous samples has
directed the current research emphasis towards unsupervised anomaly detection.
While these unsupervised anomaly detection methods offer convenience, they also
overlook the crucial prior information embedded within anomalous samples.
Moreover, among numerous deep learning methods, supervised methods generally
exhibit superior performance compared to unsupervised methods. Considering the
reasons mentioned above, we propose a self-supervised anomaly detection
approach that combines contrastive learning with 2D-Flow to achieve more
precise detection outcomes and expedited inference processes. On one hand, we
introduce a novel approach to anomaly synthesis, yielding anomalous samples in
accordance with authentic industrial scenarios, alongside their surrogate
annotations. On the other hand, having obtained a substantial number of
anomalous samples, we enhance the 2D-Flow framework by incorporating
contrastive learning, leveraging diverse proxy tasks to fine-tune the network.
Our approach enables the network to learn more precise mapping relationships
from self-generated labels while retaining the lightweight characteristics of
the 2D-Flow. Compared to mainstream unsupervised approaches, our
self-supervised method demonstrates superior detection accuracy, fewer
additional model parameters, and faster inference speed. Furthermore, the
entire training and inference process is end-to-end. Our approach showcases new
state-of-the-art results, achieving a performance of 99.6\% in image-level
AUROC on the MVTecAD dataset and 96.8\% in image-level AUROC on the BTAD
dataset.Comment: 6 pages,6 figure
Long-term (2 years) drying shrinkage evaluation of alkali-activated slag mortar: Experiments and partial factor analysis
Alkali-activated slag with many excellent properties was regarded as a novel low carbon building material, has received more and more attention. This research aims to study the impacts of alkali solution (alkali content and modulus), cement and gypsum contents on compressive strength, weight loss and drying shrinkage for alkali-activated slag mortar. Gypsum used as expanding source could compensate the drying shrinkage caused by silica and alkali components in the first three months, but it has a negative impact on the strength. The mainly results can be concluded that the alkali-activated slag blended with a cement content up to 20 wt% could effectively reduce the shrinkage and weight loss and increase the strength. Furthermore, the alkali content was below 3 wt%, the specimens possess relatively lower drying shrinkage. Based on the results of the test and analysis, the partial factors of combined activation on compressive strength and drying shrinkage of alkali-activated slag mortar were put forward. In the meantime, the relationships between compressive strength and combined activation factor are liner at 28, 90 and 365 days. Compressive strength and drying shrinkage could be estimated according to the combined activation and partial factor analysis. This work could provide a reasonable method for preparing the alkali-activated slag mortar and predict the shrinkage at different periods

Under the circumstances, we analyze phenomenon followed by the upgrading of industrial structure such as return migration and mid-aged rural labors’ difficulty in job-hunting and demonstrated the influence of land centralization based on the practice of industrial upgrade and rural change in Suzhou. Finally it come to the conclusion that because of the extensive competition on simple-labor market, the industrial upgrade will make a adverse employment shock upon mid-aged rural labor which will lead to the more uncertainty of peasants to get jobs in the industrial section . If government takes an improper policy of land centralization, peasants will lose guarantee in the future and resist the land centralization. After the comparison between one-off compensation and land cooperation, a further demonstration show that the method of one-off compensation will depress peasants’ enthusiasm in land centralization while the form of land cooperation can guarantee and promote peasants’ welfare under the given institution of land ownership.
