The Stability

A lot of data indicates that rainfall has always played the very important role in landslide triggering. The paper discusses rainfall as a dynamic parameter in term of the load/unload response ratio theory, using the Xintan landslide as a case study. Analysis of the available data indicates that the occurrences of landslides in this region are controlled by rainfall, whose intensity and rainfall processes are the most important dynamic factors in determining the stability of slopes. Therefore, the relationship between rainfall and the movement of typical landslides has been specifically analyzed for the Xintan landslides by using the loading/unloading response ratio parameter of rainfall. The result of this study indicates that the mutation of the loading/unloading response ratio of rainfall of the Xintan landslide in the Three Gorges Reservoir regions, China occurred just before their destabilization, which shows that the loading/unloading response ratio of rainfall and its changing feature can be taken as a precursor for the landslides induced by rainfall.

According to the systematic analysis of the composition and destabilized mechanism of debris landslides, this paper have hydro-geological conditions of the landslide and rainfall combined, research the changes of Unload-load response ratio (ULRR), which is considered as the displacement dynamic parameter of debris landslide in the water environment of different roles and conditions. To further explore the stability and its instability law in different stages of the landslide, establish the ULRR-rainfall coupled warning model in order to improve the accuracy of landslide prediction greatly. Meanwhile, based on the example of Xintan, use the ULRR-rainfall coupled warning model to evaluate and predict its stability. The Evaluation and prediction results match the evolution of slope stability. All results above prove that the ULRR- rainfall coupled is a very effective and reliable new method in the forecast prediction of the debris 1andslide．

The Stability

Stability of the road embankment is the foundation of the highway normal operation and maintenance, so there is strict requirement of road subgrade settlement for the highway. This article uses the gray theory to predict Cheng Chi high embankment construction settlement and builds a predicted model and tests the model’s accuracy. The results of settlement prediction are under the limits, so the stability of the road subgrade is good. This dynamic prediction method can be used on prediction of the settlement of high embankment and it’ll direct the operation and ensure the maintenance safety.

This study investigates the concept of the stability of the state and the public finance sector (PFS) based on a review of current literature in the field. An attempt has been made to define the principles of public management and present the structures of public finance sector units (PFSU) in Poland. The study focuses on the public finance sector, units included in this sector, mechanisms influencing the functioning of public service organisations and their management. Part of the research is a case study analysis of a sample PFSU, which is a central administration body. The purpose of the study was to identify the measures used to assess the stability of a public finance sector unit and to interpret those measures in relation to the studied areas of the PFS in Poland. The paper explores the principles of managing the organisation of the public finance sector, the notion of public management and its genesis. The selected PFSU case was used to indicate the relationship between the functioning of a public finance sector unit and the stability of leadership in that unit. The study is descriptive and uses inference methods. The research material included the literature on public finance and management as well as internal materials of the studied public finance sector unit. The main objective of the study was to show how the destabilisation of leadership can affect the functioning of the state office. As a result of the analysis, measures most accurately describing the phenomenon of leadership stability have been constructed. They include: measures based on quantitative assessment, measures based on institutional behaviour assessment and measures based on the subjective opinions, behaviours and expectations of employees, stakeholders and associates of the PFSU. The existence of a relationship between the stability of leadership and the functioning of a public finance sector unit was confirmed. Changes were recorded in the functioning of the office during frequent personnel changes in senior civil service positions.

This literature review article is a product of the Research Project “Relation Between Climate Variability with Mass Removal Processes. Tunja-Páez case study”, developed in the Universidad Pedagógica y Tecnológica de Colombia in the year 2020. Introduction: This article focuses on the review of research studies and advances made during the last decade regarding the influence of climatic variability on the dynamics of slopes. Objective: To determine the influence of climatic variability in areas that present slope instability in the Tunja-Páez road corridor located in the department of Boyacá. Methods: A systematic review of information from books, manuals, reports, guides, and scientific articles on climate change, climate variability, mass removal processes, meteorological variables, and their influence on the resilience and adaptation of infrastructure related to containment and slope drainage projects. Results: The studies indicate criteria that relate temperature, precipitation and seismic activity with the occurrence of mass movements. Conclusion: Climatic anomalies in terms of precipitation and temperature has allowed research methodologies using probabilistic models to be developed for estimating the occurrence of said phenomena in future scenarios. Originality: The presented literature indicates the influence of climatic variability in the resulting mass removal processes as evidenced in studies at the global and national level. Limitations: This article scientific studies have been compiled that contrast the problems in the stability of slopes of the Tunja-Páez road corridor, without going into the details of these problems.

This article presents a case study of the 2006-2007 Asian American and Pacific Islander (AAPI) student-led Count Me In! (CMI) campaign. This successful campaign convinced the University of California (UC) to account for 23 AAPI ethnic identities in its data system. Celebrated as a victory for AAPI interests in discourses over racial equity in education, which are often defined by a Black- white racial paradigm, CMI should also be remembered as originating out of efforts to demonstrate AAPI solidarity with Black students and to counter racial wedge politics. In the evolution of the CMI campaign, efforts for cross-racial solidarity soon faded as the desire for institutional validation of AAPI educational struggles was centered. Our case study analysis, guided by sociological frameworks of racism, revealed key limitations in the CMI campaign related to the intricate relations between people of color advocating for racial justice. We conclude with cautions for research and campaigns for ethnically disaggregated AAPI data, and encourage advocates and scholars to address AAPI concerns over educational disparities while simultaneously and intentionally building coalitions for racial equity in higher education.
