Authors: Alves Caio Sérgio Sabino , Albuquerque Erickson Melo de , Lourenço Artur Moises Gonçalves
Published: November 2024

Com o uso de técnicas de geoprocessamento, este trabalho teve como objetivo caracterizar os aspectos geomorfométricos da microbacia hidrográfica do açude Catolé I, localizado no município de Manaíra – PB, no semiárido brasileiro. Para isso, foi utilizado um Modelo Digital de Superfície derivado do satélite ALOS PALSAR, com resolução espacial de 12,5 m, juntamente com a Carta Topográfica Folha Serra Talhada SB-24-Z-C-V e o sistema de informação geográfica QGIS 2.8.1, com auxílio do complemento TauDEM e do MS Excel para efetuar os cálculos dos parâmetros geomorfométricos. Ao todo, 12 indicadores geomorfométricos foram calculados. Verificou-se que a microbacia hidrográfica do açude Catolé I possui uma área total de aproximadamente 13.201,28 ha, com forma alongada, possui 227 drenos, que totalizam 172,11 km de rede de drenagem intermitente, típica do semiárido, padrão dendrítico, do tipo endorreica e de 4ª ordem, com tempo de concentração de 275,17 minutos. É considerada de rápido escoamento superficial e pouco suscetível a enchentes e inundações, em condições normais de precipitação, sendo favorável para implantação de um reservatório artificial, como se verifica. Existem variações de padrão da rede de drenagem angular e retangular isso devido à existência de fraturas geológicas. Para isso, o uso do Geoprocessamento foi eficiente para promover a delimitação e a obtenção dos dados para realizar os cálculos dos parâmetros geomorfométricos, pois permitiu a análise de uma extensa área por meio de processos automatizados e a produção de informações úteis ao planejamento e gestão da microbacia.
Culto e Cultura da Historiografia Jurídica na Itália
Authors: Petit Carlos
Published: November 2024

Não há na Europa disciplina mais habituada que a italiana à prestação de contas pública por meio de balanços periódicos dos trabalhos empreendidos pela inquieta “corporação” dos historiadores do direito. Certamente não é a historiografia jurídica que menos atraiu atenção entre os colegas estrangeiros. Por tais motivos, considero necessário concentrar a observação sobre o universo das revistas jurídicas. Ademais, as revistas funcionam como “instância sintética” do output científico: podem ser consideradas como pequenas ou grandes bibliotecas que facilitam uma aproximação direta ao universo dos seus autores, de seus livros preferidos, de suas “fontes”. Enquanto obras intelectuais colocadas no tempo, as revistas nascem, crescem, morrem, mudam de estado e mudam seus responsáveis, contribuindo a fornecer, na variedade de seus títulos, indícios preciosos sobre as orientações metodológicas e culturais prevalentes de uma disciplina.
POPPER’IN PLATON’UN NATURALİST TOPLUM MODELİ ELEŞTİRİSİ ÜZERİNE
Authors: Boyacı Nihal Petek
Published: November 2024

İyi veya mutlu bir yaşama sahip olma arzusu toplumdaki kötüye gidişata dur demeyi veya onu daha iyi olana yönlendirmeyi içerir. Platon’un Atina’daki sorunlar ve ahlaki çöküşe dur demesi, onun Sofistlerden farklı bir varlık ve bilgi anlayışı ortaya koymasını gerektirmiştir. Sofistlere yaptığı temel eleştiri, kavramların ve kelimelerin bir özlerinin olmayışı onun eleştirisinin temelini oluşturur. Dolayısıyla Platon metafizik özcülük denilen bir anlayışla ideal polisini kurmaya çalışır. Popper’ın temel eleştirisi bu metafizik özcülüğün toplumun temelinde yer alması ve böylesi bir toplumun ütopyacı nitelikler taşımasıdır. Doğaya dönüş ile birlikte değişim durur. Totaliter bir yönetime gidiş gerçekleşir. Yüzyıl açısından farklı zamanlarda da olsalar, Popper’ın Platon’a yaptığı eleştiri dikkate değerdir. Ancak Platon, yeniden ahlaki değerleri tesis etmeye çalışması daha iyi bir toplum oluşturmayı amaçlar. Popper, daha iyi topluma gidişin ise metafizik özcülük olmaksızın gerçekleştirilebileceğini düşünür.
Bu makalede Platon’un ne amaçla özcülüğe döndüğü, Popper’ın eleştirisi ve daha iyi bir toplum için (metafizik) özcülük olmasa da Nussbaum’un öne sürdüğü biçimde içsel özcülüğe ihtiyaç olduğu ele alınacaktır.
Exploring the Impact of Leader Narcissism on the Job Embeddedness of a New Generation of Employees in the Chinese Context
Authors: Han Mengya
Published: November 2024

Abstract: Narcissism is the personality trait of being arrogant, lacking empathy and manipulative, and in conjunction with leadership, narcissistic leaders have a profound impact on the organizational environment and employee behaviour. As the new generation of employees develops into the core human resources of Chinese companies, the effect of narcissistic leadership on new-generation subordinates becomes a more worthwhile topic in organizational behaviour. This study constructs the influence of narcissistic leaders on job embeddedness based on the social exchange theory and conservation of resources theory. This study collected and analyzed data from 201 Chinese young generation employees through an online questionnaire. The findings suggest that narcissistic leaders had a significant negative correlation with employees' job embeddedness; job stress and employee silence mediate the relationship. This study may be unable to track the long-term effects of the factors and is limited to the Chinese context. However, the results of this study not only enrich the literature in the field but also provide practical references for organizations to lessen the impact of leaders dark personalities and employees negative behaviors.

The Impact of Mandatory ESG Disclosure on Share Price
Authors: Yang Fengming
Published: November 2024

Abstract: The importance of sustainable development has attracted public attention. To achieve the global sustainable development goals, copious countries have recently begun formulating and implementing mandatory ESG (Environment, Social and Governance) disclosure policies. This has prompted the research community to investigate the impact of compulsory disclosure on the interests of corporate stakeholders, such as share price. According to stakeholder theory, long-term value-based theory, resource-based theory, and efficient market hypothesis, ESG mandatory disclosure will have short-term and long-term impacts on stock prices. Specifically, from the short-term perspective, good ESG reports will lead to rapid growth. Then the price will return to normal level. Moreover, in the long term, this has no significant impact on share prices. This article will use event research methods and linear regression models to specifically study the impact of Apple's ESG report disclosure on stock prices. Finally, research has found that in a normal environment, mandatory ESG disclosure will have a positive short-term impact on share price according to the good quality of ESG reports, while this will have a negative influence on stock price due to the poor quality of ESG reports. However, in special circumstances such as the 2022-2022 global epidemic period and long-term perspective, the disclosure of ESG reports has no significant impact on stock prices.
Population Aging and Sustainability of Pension Funds
Authors: Li Jiaxin
Published: November 2024

Abstract: In light of the nation's increasingly pressing aging problem, achieving sustainable development of China's pension insurance fund is a key objective of the country's present social security system reform. The first subject addressed in this paper is the connection between aging and the sustainability of the pension insurance fund. An econometric model can be used to illustrate how the aging population will reduce the basic pension insurance fund's balance rate. This will have an additional effect on the fund's income and expenditure balance, causing a payment gap and hindering the fund's capacity to develop sustainably. As such, a review of the national pension insurance program is carried out. From the perspectives of policy concerns and improvement ideas, we argue for the soundness and areas for development in the national pooling policy of pension insurance funds. The sustainability of pension insurance funds is the ultimate goal, and it also helps with the difficulties brought on by shifting demographics and the pressure on pension insurance fund contributions.
The Comparative Analysis on the Impact of the Great Financial Crisis and the COVID-19 Shock in Response to Macroeconomic Policies
Authors: Li Chufan
Published: November 2024

Abstract: The Global Financial Crisis (GFC) and the COVID-19 pandemic shock have similarities and differences. They both cause major economic downturn, affecting the normal functioning of the society. The cause and impact of them are different since the GFC is an internal shock whereas the economic downturn brought by the COVID-19 pandemic is an external shock that cannot be predicted. The corresponding expansionary fiscal and monetary policies are also slightly divergent. This research compares the economic impact of the GFC and the COVID-19 shock, specifically in China, focusing on the policy responses in different situations. Based on the analysis of the impact of the policies implemented in the GFC, the four-trillion investment proposed in 2008 was not a sustainable fiscal policy since it had made the government highly in debt. In 2020, the government also employed expansionary fiscal policies, but instead of spending on basic infrastructure, it concentrated on the advanced technology and service industry. Further, this paper suggests that the government could spend more on new investment plan like 5G technology to revive the economy during the aftermath of the pandemic.

Mobile Phone Intelligent Recognition of Human Activity Based on Deep Neural Network
Authors: Zhao Zihuan
Published: November 2024

Abstract. Because of the rapid development of smartphone sensor technology and the continuous progress of machine learning algorithms, it has become possible to use smartphones for human activity recognition. Sensors such as accelerometers, gyroscopes, and magnetometers built into smartphones are able to collect human motion data in different activities, which provides a rich data source for activity recognition through mobile phones. In this paper, we change the activation function of the hidden layer of the neural network to observe the effect of this variable on the mobile phone to recognize human activities. Taking Rectified Linear Unit (ReLU)function and Sigmoid function as examples, it is found that the neural network using the ReLU function shows higher accuracy (0. 9518 and 0. 9332) and lower loss value in the early stage and middle to late stage of training. In addition, This paper finds that training for 100 epochs takes significantly less time than the model with the Sigmoid activation function (47. 041 seconds vs 179. 022 seconds). The neural network system built by the relu function has faster operation speed and better performance. This study shows that different hidden layer functions have great influence on the quality of the same neural network, and selecting the best hidden layer function will be an important point for the success of the study.
Optimizing Federated Learning Efficiency: A Comparative Analysis of Model Compression Techniques for Communication Reduction
Authors: Yan Shida
Published: November 2024

Abstract. The rapidly growing number of connected devices continuously produces massive amounts of heterogeneous data, posing challenges to data privacy and security when leveraging them to train the high-quality big model. Federated learning, which enables numerous users to train a global model without cooperatively exchanging data, has emerged as a viable alternative. Though achieving significant progress, existing federated learning methods still struggle with large communication volumes, especially when the local devices only have limited computing and communication capabilities. To alleviate the efficiency issue, this paper compares the effect of three compression methods in promoting the training of federated learning models, including pruning, quantization, and knowledge distillation. The findings reveal that these methods reduce resource consumption while maintaining high model performance. Combining the pruning, quantization, and knowledge distillation technology through sequential application and parameter aggregation helps balance the model size and performance. Our cascading lightweight strategy, which preserves each method's unique edge while promoting deeper collaboration between them, has been shown beneficial through extensive testing.
Exploring SRGAN-Based Model for Image Super-Resolution
Authors: Yang Runqi
Published: November 2024

Abstract. Transforming low-resolution (LR) images into their high-resolution (HR) counterparts is a challenging endeavor, referred to as image super-resolution (SR). The emphasis of this research is on the Super-Resolution Generative Adversarial Network (SRGAN), a sophisticated deep learning approach that can generate aesthetically pleasing high-resolution images. Initially, a backbone model is trained with mean squared error (MSE) loss function to enhance image details. Then, the author took this pretrained the backbone and used it to initialize the generator part of SRGAN, after which the author performed adversarial training where various content accuracy - visual realism tradeoffs were considered during optimization process. This work tested models on standard benchmarks like Set5, Set14, and BSD100 with Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM). The best results were achieved when using intermediate learning rates combined with 16 batch size those settings resulted in highest PSNR and SSIM values across all datasets that have been tested. To sum up, SRGAN has proven itself effective at solving problems related to image super resolution but there is still room left for improvement by adjusting hyperparameters or modifying architecture design based on findings from this paper.

Published: November 2024

The design of total ankle arthroplasty (TAA) systems is rapidly evolving as device companies try to keep pace with the expansion of surgical indications and a refinement of techniques for TAA. Even since the publication of the latest “update,” published in 2018, three new designs and three updates on preexisting third-generation implants came onto the market. Improvements in third-generation TAA systems include minimal bone resection, retaining ligamentous support, and anatomic balancing. Fourth-generation systems use 3D printing technology, improved talus and tibia designs based on CT scans of arthritic and normal ankles, and include patient-specific instrumentation. We will then explore the short-term and mid-term outcomes of the previously discussed six TAA systems—INBONE, INFINITY, INVISION (Stryker), Salto-Talaris (Smith and Nephew), Scandinavian Total Ankle Arthroplasty (Enovis), Trabecular Metal Total Ankle (Zimmer Biomet), and VANTAGE (Exactech). As more research pours in regarding mid- to long-term outcomes of these implants, it is important to assess the design rationale and summarize current outcome data for these implants.

Authors: Pham Xuan Thanh , Hung Nguyen Xuan , Vu Kim Hoan , Trinh Dinh Linh , Pham Thanh Son
Published: November 2024

Recently, significant research has been conducted on magnetic metamaterials that exhibit negative permeability and operate within the GHz and MHz frequency ranges. These metamaterial structures can be utilized to improve the efficiency of near-field wireless power transfer systems, subterranean communication, and position sensors. However, in most cases, they are only designed to work for a single application. This study focuses on examining the transmission of magneto-inductive waves in magnetic metamaterial structures with ordered arrangements. This structure can be used simultaneously for wireless power transfer and near-field communications. The unit cell is formed by a spiral with five turns that is implanted on a FR-4 substrate. An external capacitor was used to regulate the resonant frequency of the magnetic metamaterial unit cell. The properties of magneto-inductive waves, including reflection, transmission response, and field distribution on the waveguide, have been extensively computed and simulated. The obtained results indicate that both 1-dimensional and 2-dimensional magnetic metamaterial configurations possess the ability to conduct electromagnetic waves and propagate magnetic field energy at a frequency of 13.56 MHz. The straight and cross path configurations were also investigated to identify the optimal configuration on the 2-dimensional metamaterial slab.
Assessment of digital technology application in intermodal freight transport : a low-income country perspective
Authors: Kine Helen Zewdie
Published: November 2024

Intermodal freight transport (IFT), involves the use of two or more transport modes to move goods within a single unit, creating a complex, multi-stakeholder system. Digital tools play a critical role in planning and optimisation of this system. However, the current adoption of digital technologies in low-income countries is considered low and therefore, their potential benefits are not realised. This thesis endeavoured to investigate the potential benefits of digital technology in IFT from the perspective of low-income countries. First, current technological practices and important performance indicators were examined by considering the transport chain from seaport to dry ports and to destinations/origin points in Ethiopia. Second, two studies on dry ports were conducted to explore the application of digital technology in IFT. The research approach included a systematic literature review, qualitative methods including business process mapping, as well as quantitative methods such as multi-criteria decision analysis and modelling. The results revealed that adoption of advanced digital technologies in IFT is limited, particularly in the road transport sector. The presence of basic technologies in the surveyed companies revealed potential for the further digitalisation of IFT. Application of geographic information systems and use of spatial data in dry port location analysis could enhance decision-making with regard to the optimal location of dry ports. Furthermore, the integration of digital technologies, such as online platforms for dry port’s information management and document sharing, have the potential to improve time efficiency, which was the second most important performance indicator identified in this study. Overall, the potential of digital technologies to enhance key performance indicators in the IFT of low-income countries should be fully exploited. At the same time, infrastructural and human resource constraints in these economies should be addressed for successful technology adoption schemes.

Authors: Abdelaal Kamal Abdelaal Tamam , Aldhamer Abdulaziz Abdulrahman , Aljawabrah Faisal Basim , Abdelqader Yassin Mahmoud
Published: November 2024

The purpose of this article is to explore the position of the Prophetic Sunnah on sustaining the green environment, encouraging its preservation, and preventing any tampering or vandalism. The article highlights the Sunnah's emphasis on environmental care by underscoring its instructions regarding the sustainability of natural greenery. This study examines the Prophet’s teachings and directives that urge environmental sustainability by promoting planting and cautioning against actions that harm nature, such as cutting down trees or damaging green spaces. It emphasizes that environmental conservation is an integral yet often overlooked part of the Sunnah. Key findings include that the preservation, enhancement, and careful treatment of the environment and its resources are core values in the Sunnah. The Sunnah explicitly discourages the destruction of trees and green land, even in the most challenging times and conditions, and declares any distortion or damage to the green environment as a transgression in Islamic law. The article concludes with several recommendations, foremost among them being the development of a university-level environmental education program aimed at raising awareness, protecting the environment, and preventing its degradation.

Published: November 2024

Los modelos formales son herramientas indispensables en el manejo de los recursos naturales y en la biología de la conservación. La modelación puede ser una herramienta útil para estudiar estos sistemas, comunicarse a través de disciplinas e integrar diversos puntos de vista de numerosas partes interesadas. Este módulo muestra cómo construir explícitamente modelos como representaciones alternativas para ayudar a interpretar y comprender la naturaleza. A través de una síntesis y dos ejercicios, describe el contexto general de la modelación científica (como por ejemplo, el uso y los tipos de modelos), y permite a los estudiantes practicar la construcción de un modelo evaluando la relación entre la dinámica de poblaciones de conejos y zorros, desde cómo plantear el problema, construir una hipótesis dinámica, y formular y probar el modelo.
The Mekong Delta: A Biological and Socio-Economical Case Study of a Wetland
Authors: Good Tatjana
Published: November 2024

The Mekong River is the largest river in Southeast Asia, arising in the mountains of China, flowing along the border of Myanmar and Laos, and through Laos and Cambodia into Vietnam; 80% of the Mekong Delta lies within Vietnam. The biodiversity of the Delta and southern Vietnam as a whole depends on the cycles of the river. The Mekong Delta wetlands are highly productive and valuable for both use and non-use reasons. Unfortunately, they are also highly threatened by human activities resulting in degraded water quality, change in species composition, and pollution. This Vietnam-focused case study allows students to tackle this real-world conservation problem by approaching the topic from a variety of angles, thereby teaching them to appreciate the complexity of such issues (biological, geographical, environmental, political, and socio-economical).
Manejo de Especies Amenazadas
Authors: Kesler Dylan , McGowan Conor , Ryan Mark
Published: November 2024

Las especies amenazadas se encuentran en riesgo inminente de extinción. Las causas que las ponen en peligro varían ampliamente, pero en general se deben a la pérdida de hábitat, las especies introducidas/exóticas, la sobreexplotación y/o las cascadas de extinción. Se describen las medidas para identificar especies amenazadas y la planificación de su recuperación. También se realiza la revisión de algunos enfoques de manejo, incluyendo restauración de hábitat y cría en cautiverio. Se incluyen numerosos ejemplos de nuestras propias experiencias profesionales y de las fuentes bibliográficas que detallan a las especies amenazadas y los intentos de gestión y recuperación de especies. En el módulo se incluye un documento de síntesis que resume el contenido principal y dirige a los estudiantes a literatura primaria sobre la materia, una presentación de PowerPoint y notas de clase que se organizan para reflejar el documento de síntesis, un conjunto de ejercicios que utilizan un modelo poblacional simple del cóndor de California (Gymnogyps californianus) y que solicita a los estudiantes que evalúen las estrategias alternativas de manejo, y un breve estudio de caso que requiere que los estudiantes utilicen el mismo modelo poblacional para escribir un plan de recuperación para los cóndores.
Biodiversity Conservation and Integrated Conservation and Development Projects (ICDPs)
Authors: Rao Madhu
Published: November 2024

This module describes the evolution in approaches to ICDPs over time. Some of the major problems identified in ICDP evaluations are discussed within two broad categories: (a) design and conceptual issues and (b) implementation issues. Global experiences in the implementation of several ICDPs have generated lessons and determinants of success for ICDPs, which will continue to represent predominant strategies for site-based conservation. The synthesis reviews some emerging perspectives on approaches to help ICDPs make a sustained contribution to biodiversity conservation and ends with a brief discussion on the continuing debate on the relationship between economic development and biodiversity conservation. The future of ICDPs involves improving their effectiveness by consciously applying lessons learned and simultaneously developing additional tools to help achieve biodiversity conservation.
Applying Critical Thinking to the Amphibian Decline Problem
Authors: Bravo Adriana , Porzecanski Ana , Siller Stefanie
Published: November 2024

This exercise is designed to foster the practice of critical thinking—a habit of mind characterized by the comprehensive exploration of issues and evidence before accepting or formulating an opinion or conclusion—in the context of a complex and real conservation problem: amphibian declines. The exercise has four parts: a case study, ten questions related to the reading, an in-class discussion in groups, and finally a set of questions for reflection and research, either individually or in groups, to understand how the issue has continued to evolve over the last decade.
Assessing Threats In Conservation Planning And Management
Authors: Bynum Nora , Johnson Arlyne , Rao Madhu
Published: November 2024

This module reviews the role of assessing threats in setting conservation targets, identifying priority strategies, and determining their effectiveness. It includes an overview of the use of threat assessment in conservation planning by focusing on species-level and global-, regional- and local (site)-level priority setting. The synthesis also reviews two planning tools used in site conservation—conceptual models and The Nature Conservancy’s 5 “S” approach. The second part of the synthesis reviews the role of threat assessment in measuring management effectiveness with reference to monitoring approaches that fall into two broad categories: (1) the assessment of the status and impacts of threats, and (2) the measurement of ecological integrity of conservation targets. This section concludes with a comparison of threat monitoring methodologies focusing on two approaches: Threat Reduction Assessment and Rapid Assessment and Prioritization of Protected Area Management.
Applied Demography
Authors: Gibbs James
Published: November 2024

Applied demography involves using the knowledge gained from analyzing and understanding populations in order to manage them effectively. The synthesis reviews basic concepts of demography and their application to management of wild populations. There are several major drivers of population change that operate in different ways, including birth rates, death rates, changes in sex ratios, and migration. These concepts can be formalized into mathematical population models that can be used to make predictions about populations under different management scenarios. Four case studies (including the Giant Galápagos Tortoise) are used to illustrate the real-world application of demographic concepts to rare species conservation.
A Comprehensive Simulation of the Colorado River Basin: An Interactive Exercise
Authors: Christensen Niklas , Vintinner Erin , Weeks Brian , Wheeler Kevin
Published: November 2024

As the dominant hydrological force in the American Southwest, the Colorado River cuts a wide swath through vast deserts and arid plains, and also through the lives of millions of people and species. As with many managed freshwater ecosystems, the complex question arises: what is the best way to balance ecosystem health, the maintenance of ecosystem services, and the needs of diverse stakeholders? This simulation exercise allows users to experiment interactively with water allocation tradeoffs, economics of water use, and the impact of climate change on the basin, as well as visualize the impact of tradeoffs on the native ecosystems of the basin and the impact of water conservation measures. The simulation provides a useful heuristic tool for exploring many water management issues, and is highly illustrative and useful for comparative and educational purposes, for both students and conservation professionals.
