The Colombian Economy and Its Regional Structural Challenges A Linkages Approach - Original PDF
نویسندگان: خلاصه: Preface I have been teaching a Ph.D. course on “Applied General Equilibrium Models” at the University of São Paulo, Department of Economics, since 1999. Over the last editions of the course, the material was built around specific countries or regions, selected to be the object of modeling practices undertaken by the students. This praxis turned out to be very rewarding for the students since they were motivated to apply different techniques to study concrete problems in a common economic system. Throughout this process, they had the opportunity to collaborate among themselves and interact with scholars from the study regions, often generating scholarly publications. We had already worked with countries such as Brazil, Chile, Greece, and Paraguay, and with different regional contexts, especially within Brazil. Colombia had always been a top candidate to receive our attention. Our previous engagement with colleagues from the Centro de Estudios Económicos Regionales (CEER), a research center specialized in Regional and Urban Economics at the Banco de la República— the Colombian Central Bank—provided a unique opportunity to develop a special edition of the course on the country. During a visit to Cartagena in 2019, Jaime Bonet and I finally agreed to use Colombia as the case study in the forthcoming edition of the course. We designed the Colombian edition in innovative and challenging ways, raising the bar for the expected outcomes, including a workshop to be hosted in Cartagena in 20201 and the publication of a volume including the contributions by different authors forming a cohesive unit. We built the activities upon solid co
Healthcare and Disease Burden in Africa The Impact of Socioeconomic Factors on Public Health - Original PDF
نویسندگان: خلاصه: Chapter 1 Introduction There is an acute scarcity of research and studies on the conditions of healthcare in African countries. According to Marincola and Kariuki (2020), 20% of the global disease burden falls on the shoulders of Africa, yet only 1% of worldwide scientific output focuses on African countries. Filling the epistemological gap is critical, for it will not only shine a light on our understanding of the realities of the continent, but also pave way for more engaged future studies. The investigation of existing health- care conditions in Africa provides an indispensable basis for generating educated responses to the challenges that confront the continent as a whole and across its different localities. Africa also occupies a historically overlooked and underrep- resented position. It is a unique continent with highly diverse cultures, societies, and economic compositions. While significantly different from the Western or more economically developed parts of the world, Africa is playing a crucial role on the global stage in a variety of aspects. Therefore, studies of Africa will not only benefit the regional communities, but also have a long-lasting impact on the rest of the world. Africa carries the oldest and most diverse genome. Around seven billion of the world’s population share a common origin in Africa. The burden of disease in Africa is also shifting from communicable to non-communicable diseases, which is also a major concern of the societies that are more economically developed. Therefore, addressing the disease burden in Africa, in parallel, means investing in the prevention and treatment of diseases in the rest of the world.

نویسندگان: خلاصه: With continuously growing e-commerce with its increased demand for fast delivery, various e-commerce players have decided to enter this market to improve both efficiency and effectiveness of the service. Vertically integrated digital market- places’ business models, however, raise the concerns of competition and regulatory authorities across the world because of the anti-competitive behaviours they might facilitate. The paper discusses motivations behind and potential implications for competition of the logistic choices in last-mile delivery of important e-commerce platforms, providing a comparison between Amazon, Alibaba and Allegro
Disaster Management and Information Technology Professional Response and Recovery Management in the Age of Disasters - Original PDF
نویسندگان: خلاصه: There is no one single journey when it comes to technology. For those who did not grow up as “digital natives” each has taken their own path in accepting, developing technological skills and expanding them by integrating them into their everyday work environment. Indeed, the journey continues with no hard- set destination before us. We only know that technological development and use of technology continue to expand exponentially with each passing day. What follows is therefore just one American perspective on how the profession of emergency management has adopted technologies over the decades in which the profession has existed. All the while, working daily to plan for, train, and practice for future emergency and disaster response events that are sure to come.
Intersectionality and Discrimination by Roger White - Original PDF
نویسندگان: خلاصه: Abstract We begin with a brief discussion of the relationship between social justice and economic justice. This is followed by a presentation of persistent differences in U.S. labor market outcomes. Specifically, we identify significant differences in unemployment rates and hourly wages across race- and sex-based classifications, respectively. We then present unadjusted wage gaps (i.e., raw differences in average hourly wage rates) for several worker groups that correspond to the non-productive personal characteristics we consider in this study. These characteristics include Hispanic ethnicity, nativity, race, and sex. Having motivated our study, we introduce intersectionality and our primary research question: Is wage discrimination intersectional? This is followed by a discussion of why we use the term “discrimination” when referring to differences in wage rates that cannot be explained by differences in workers’ productive character- istics. We conclude the chapter with a roadmap for the remainder of the book
HCI International 2022 – Late Breaking Posters - Original PDF
نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications

Blockchain Technology and Emerging Technologies - Original PDF
نویسندگان: خلاصه: ID-Based Self-encryption via Hyperledger Fabric Based Smart Contract Ilya Grishkov1, Roland Kromes1(B), Thanassis Giannetsos2, and Kaitai Liang1 1 Cyber Security Group, Delft University of Technology, Delft, The Netherlands I.Grishkov-1@student.tudelft.nl, {R.G.Kromes,Kaitai.Liang}@tudelft.nl 2 Ubitech Ltd., Digital Security and Trusted Computing Group, Athens, Greece agiannetsos@ubitech.eu Abstract. This paper offers a prototype of a Hyperledger Fabric-IPFS based network architecture including a smart contract based encryp- tion scheme that meant to improve the security of user’s data that is being uploaded to the distributed ledger. A new extension to the self- encryption scheme was deployed by integrating data owner’s identity into the encryption process. Such integration allows to permanently pre- serve ownership of the original file and link it to the person/entity who originally uploaded it. Moreover, self-encryption provides strong security guarantees that decryption of a file is computationally not feasible under the condition that the encrypted file and the key are safely stored. Keywords: Blockchain · IPFS · Self-Encryption · Security · Hyperledger Fabric 1 Introduction The modern world is increasingly adopting blockchain technology. The first major market adoption of blockchain happened in 2009 when Bitcoin was introduced [12]. Interest in blockchain solutions grew over the years and lead to the invention of Ethereum - Bitcoin peer but with support for smart contracts which are digital codes enabling the description of complete business logic [1]. The introduction of smart contracts leads to further development in the field of blockchain and cre- ated demand for more industry-friendly solutions that allow to identify users of the system (Know-Your-Customer, Anti-Money-Laundering). Hyperledger Fab- ric was then introduced as a highly modular permissioned blockchain that allows great customization to suit particular industrial needs [3]. Given its customizabil- ity and modularity, Hyperledger Fabric (HLF) is a perfect platform for extending it with various trust and privacy preservation solutions
