An Analysis Of Vertical Deformation On Cianjur Earthquake 2022, Candra Perkasa Nurlukman, Adi Wibowo

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

A shallow crustal-type earthquake on a surface fault occurred on November 21, 2022, in Cianjur, West Java. This destructive earthquake resulted in a loss of life, many houses were damaged, and landslides at several points. So, the research was analyzed using the DInSAR method to see the deformation and its relationship with the existing conditions in the field. We get the result of a vertical subsidence in the earthquake area of up to 101 millimeters. Through the distribution of displacement results, we found no overlapping faults at that location, identifying the formation of a new fault. In the distribution area …

Indirect Genetic Effects Among Neighbors Promote Cooperation And Accelerate Adaptation In A Small-Scale Human Society, Jordan S. Martin, Bret Beheim, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz, Benjamin C. Trumble, Paul Hooper, Daniel K. Cummings, Daniel Eid Rodriguez, Adrian V. Jaeggi

ESI Publications

Explaining the rapid evolution of human cooperation and its role in our species’ biodemographic success remains a major evolutionary puzzle. To address this challenge, we tested a social drive hypothesis, which predicts that social plasticity and social selection in human groups cause indirect genetic effects that accelerate the adaptation of fitness, promoting population growth via feedback between the environmental causes and evolutionary consequences of cooperation. Using Bayesian multilevel models to analyze fertility data from a small-scale society, we demonstrate that density- and frequency-dependent indirect genetic effects on fitness promote the evolution of cooperation among neighboring women, increasing the rate of …

The Constellation Of American Voters: Understanding Americans Who Live In And Out Of American Municipalities, Jordan Duffin Wong

Arts & Sciences Graduate Student Theses and Dissertations

More than 130 million Americans live in unincorporated areas, or the spaces outside the boundaries of cities, towns, and villages. Despite this, relatively little attention has been paid to whether, how, and why residents of unincorporated areas differ from their municipality-dwelling counterparts. In this dissertation, I explore the answers to these questions by establishing a new theoretical framework that rigorously defines, bounds, and partitions unincorporated space. Drawing on the near-universe of American voters, I illustrate, with unparalleled precision, where and how Americans have sorted into and out of municipalities, and show that different mechanisms drive these phenomena. Furthermore, I explore …

Classifying Heterogeneous Cooperation In Social Dilemmas: Experimental Evidence And Simulation Insights, Sining Wang

Faculty Scholarship

In this paper, we introduce a revealed strategy method to capture heterogeneous behavioral patterns in repeated public goods experiments. This method identifies an individual’s strategic type—a stable decision-making tendency in interactive settings—by analyzing behavioral profiles. We conduct a repeated public goods game to collect participants’ behavioral data and then apply both k-medians and hierarchical clustering algorithms to classify them into five distinctive types: free riders, strong cooperators, above-average conditional cooperators, below-average conditional cooperators, and hump-shaped players. These classifications are then used to construct and calibrate an agent-based simulation model. Our simulation results suggest that policies targeting how conditional cooperators respond …

Essays On The Economics Of Education Policy, Stephen Owusu

Economics ETDs

The first chapter of this dissertation evaluates the impact of Ghana’s Capitation Grant Scheme, a government education policy that provides direct funding to public schools to eliminate primary school fees, on both the short- and long-term numeracy and literacy skills of children intended to be treated. The findings suggest that free primary education may exacerbate language competition in linguistically discordant societies. In the second chapter, we find that, even without complementary infrastructural expansion, an additional year of official secondary schooling positively affects secondary and post-secondary educational outcomes. The third chapter investigates the relationship between secondary education length reform and reproductive …

High Spatial Resolution Crop Type And Land Use Land Cover Classification Without Labels: A Framework Using Multi-Temporal Planetscope Images And Variational Bayesian Gaussian Mixture Model, Minh Tri Le

Mathematics, Physics, and Computer Science Faculty Articles and Research

Previous studies often combined high spatial resolution data (e.g., PlanetScope) with wider spectral range data (e.g., Sentinel-2) and relied on supervised classification methods to produce land use and land cover (LULC) maps. This study proposed a new unsupervised framework to generate crop type and LULC maps at high spatial resolution (< 5 m) using available PlanetScope data solely without requiring ground truths. We used PlanetScope surface reflectance images and their derived spectral indices during growing seasons to create multi-temporal input features, which were fed into an unsupervised Variational Bayesian Gaussian Mixture Model (VBGMM). The VBGMM, unlike the traditional unsupervised classification methods, (1) first estimated optimal parameters that are most suitable based on the input features and then (2) assigned pixels to the cluster with maximum posteriori probability of a mixture of several Gaussian distributions. The crop type and LULC maps were then generated by labeling the derived clusters using the best possible assignment method, referring to the existing crop type or LULC products. We evaluated the produced PlanetScope-based crop type and LULC maps using true labels, corresponding reference maps, and other unsupervised classification methods. The results demonstrated the robustness and effectiveness of the proposed framework in mapping crop types and LULC at 3–5 m pixels across various ecosystems, climate zones, and human-managed landscapes. The spatial patterns of PlanetScope-based maps were (1) highly comparable with all the reference datasets at 10–30 m spatial resolution and (2) better than the traditional GMM and K-means clustering methods. The VBGMM produced classification maps with high confidence, yielding class probabilities above 0.9 for over 90 % of all study areas. The area percentage for all crop type and LULC classes agreed well with their reference maps, with R2 of 0.95 and RMSE of 1.04 %. The confusion matrices using true labels indicated that PlanetScope-based maps achieved a higher overall accuracy of 84 % than the supervised referenced maps of 81 %. Besides, the entropy comparison showed that our framework-based maps were better at capturing fine-scale features such as developed areas within cities that commonly mix with open space and vegetation, deforestation and cropland conversion in South America, smallholder croplands in Africa and Asia, and generating homogeneous crop fields in North America. This study further highlighted the potential for future research to implement our proposed framework to generate timely and extensive annotated datasets, which can be used for operationally training machine learning models to map crop types and LULC, track deforestation, detect wildfires, and delineate flooded areas at larger scales using medium/coarse Earth observations.

A Systematic Review Of Transmedia Literacy: Implications For Lifelong Learning, Rafel Meyerhofer-Parra

Journal of Media Literacy Education

One of the main objectives of international agendas is the promotion of lifelong learning opportunities. Transmedia literacy, usually acquired informally, offers many of the key skills, competences and strategies to ensure learning in a world where technology has a predominant role. However, no analyses reporting the impact of their use are systematically identified in the literature. Therefore, a systematic review of the literature on transmedia literacy and its practices is proposed, searching 4 databases and analysing a total of 42 articles. The results show experiences with plural thematic, extension and educational context, mainly located in the formal educational system, and …

Energetic And Economic Aspects Of Rebound, Part Ii: Applications Of The Framework, Matthew Kuperus Heun, Gregor Semieniuk, Paul E. Brockway

University Faculty Publications and Creative Works

Widespread implementation of energy efficiency is a key greenhouse gas emissions mitigation measure, but rebound can “take back” energy savings. However, the absence of solid analytical foundations hinders empirical determination of rebound magnitudes. In Part I, we developed foundations of a rigorous, analytical, consumer-sided rebound framework that is approachable for both energy analysts and economists. In this paper (Part II), we develop energy, expenditure, and consumption planes, a novel, mutually consistent, and numerically precise way to visualize and illustrate rebound. Further, we operationalize the macro factor () for macroeconomic rebound. Using the framework and rebound planes, we calculate and show …

Rishon Le-ẒIyyon, Winepress Park: Geomorphology And Sedimentology, Joel Roskin, Yotam Asscher

Qadum: Journal of Excavation Reports from Israel

An extensive brown sandy double-unit sediment, draping large parts of the archaeological remains at the Winepress Park in Rishon Le-Ẓiyyon, is suggested to be associated with the previously reported, undated ʻEn Ha-Qore clay. Based on relative age port-OSL profiling, the depositional mechanism of this unit and the overlying sand is suggested to be related to late Holocene, dune-dammed winter ponds. These aeolian-fluvial dune-damming processes may have been partly triggered by intensive Byzantine human activity that may have led to sand mobilization.

Does Digital Finance Move Together With Technology Innovation In China?, Zhu Wenhui, Zhang Jiajie, Hu Chuanxia, Dong Hanwei

Bulletin of Monetary Economics and Banking

Existing academic research has predominantly examined the unidirectional impact of digital finance on technological innovation, thereby neglecting the reciprocal interplay between these two domains. This study fills this gap by investigating the long-term bidirectional cointegrated relationship between digital finance and technological innovation. Using panel cointegration estimation methods on panel data from 286 Chinese cities during 2011–2020, empirical results reveal a long-term co-movement between digital finance and technological innovation. Pooled Mean Group estimation demonstrates that digital finance makes significant contributions to technological innovation in both long-term and short-term contexts. However, sub-sample analyses show that digital finance consistently boosts technological innovation in …
