Rudolf Hilferding What Do We Still Have to Learn from His Legacy? - Original PDF
نویسندگان: خلاصه: Editors and authors are, of course, grateful for the interest of our readers that has made it possible to realise a second edition now. We have made use of this happy occasion to correct mistakes we had overlooked in the first edition, to actualise the texts wherever needed, and to add four texts: one by Michael R. Krätke on the still unpublished notes of Hilferding’s last manuscript which had been published post-humously (discussed as such by F. O. Wolf), and another one, also by Krätke, on Hilferding’s cor- respondence; plus a presentation of Krzywicki, the Polish ‘equivalent’ to Hilferding, by Toporowski, as well as a contribution by the editors open- ing a perspective on Varga. We hope to fuel the incipient debate on Hilferding by providing access to these materials—which are not merely of biographical relevancy. We also have added a contribution on Eugen Varga, leading on to the next collection of texts planned in this series. All authors have had the occasion to revise their texts according to the need they could see for this. Accordingly, the new edition will serve as a use- ful tool for further developing the debate on Hilferding, after it had been unblocked from political fetters resulting from older political antagonisms. We have become aware that there is an important and specific debate on Hilferding in Japan. Minoru Kurata and Masaaki Kurotaki should at least be mentioned here. Unfortunately, we have not been able to find a Japanese author for presenting this debate authentically, for which we only Preface to the second edition xviii PREFACE TO THE SECOND EDITION have passing references in the volume. This remains an open challenge for further research and debate.1 In finishing this volume, while the terrible ‘military operations’ gener- ated especially by Putin and his narrow power circle are unfolding, we want to underline the deep internationalist character of our work aiming at strengthening critical thinking and emancipatory-solidarity
Global Economic Challenges 6th International Conference on Banking and Finance Perspectives, Cuenca, Spain - Original PDF
نویسندگان: خلاصه: Price movements in the energy market are crucial because energy plays a vital role in the world’s economies and human life. The high volatility in energy prices since the 1990s is due to several historical developments, including the deregulation of energy markets, the Asian financial crisis in 1997, and the 2008 global financial crisis (Lien et al., 2016; Lang & Auer, 2019) have increased the need for an appro- priate protection strategy. Hedging by using futures contracts makes the problem of “finding an appropriate hedge ratio” vital. In calculating the optimal hedge ratio (OHR), estimations are mostly based on the average (expected) relationship between spot and futures prices. This approach ignores the tail distribution of the variables (Lien et al., 2016; Shrestha et al., 2018). However, the widely documented non- normal distribution of financial variables makes considering the quantiles of the variables essential. To fill this gap, we used the recently developed quantile-on- quantile (Q-Q) (Sim & Zhou, 2015) approach to estimate the minimum-variance (MV) hedge ratio for crude oil, natural gas, and gasoline markets. Besides, to have a better understanding of the relationship between these variables, we examined long-run and causal relationships by using methods that consider the distribution of the variables.
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
The Problem of Property Taking the Freedom of Nonowners Seriously - Original PDF
نویسندگان: خلاصه: CHAPTER 1 Introduction As I went walking, a sign stopped me. On the one side, it said “No Trespassing.” But on the other side, it didn’t say nothing. That side was made for you and me. ... This land was made for you and me. —Woody Guthrie, “This Land Is Your Land” as covered by Remember Alice?1 Any conception of a right—whether legal or natural—has to be recip- rocal in the relevant ethic respect. A nonreciprocal “right” is merely a privilege. A right of self-ownership at least prima facie passes this test. It amounts to saying accept my ownership of my body as I respect your ownership of your body. The highly unequal ownership system that prevails in external assets (i.e., property in anything outside of our living bodies) prima facie fails this test in at least two ways. First, it gives one group control over resources essential to everyone’s survival and therefore, forces the propertyless group to perform services for the property-owning group to survive. Second, it amounts to saying, “You should respect my property for I would respect yours if you had any.
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
50 Literacy Strategies Step by Step Fourth Edition - Original PDF
نویسندگان: خلاصه: Young children write “All About . . .” books on familiar topics (Tompkins, 2012). They put together a booklet with four or five pages, write a sentence or two on each page, and add illustrations to elaborate the information presented in the text. Stu- dents read the book to the teacher, who helps them elaborate ideas and correct mechani- cal errors before they share from the author’s chair (see p. 10). As they gain experience writing books with one or two sentences per page, students can expand and elaborate the information they share on each page, gradually increasing the length to a paragraph
From Darwin to Derrida Selfish Genes, Social Selves, and the Meanings of Life - Epub + Converted PDF
نویسندگان: خلاصه: Evolutionary theory can be a nasty business. Perhaps it has something to say about human nature. Most scientifically respectable evolutionary theories wear garments of math. I think of mathematical models as disciplined metaphors. We use x to represent something in the world, say slugs, and y to represent something else, say lettuces, then we analyze the relation of x to y using mathematics. We imagine that slugs and lettuces behave like x and y in the model, and then we use how x and y behave in the model to understand how slugs and lettuces behave in the world. Nobody can argue with mathematical models—that is one of the points of using mathematics—but there can be endless arguments about what you put into a model and what you leave out, and endless arguments about what the model means, because metaphors can be interpreted in many ways. I am not criticizing the use of metaphors—far from it, they are essential. All that we know about the world is metaphor. Our perceptions are a virtual reality, not the thing in itself but something that stands in the place of the thing. Phenomena are metaphors used to comprehend things. Don’t worry, this book contains almost no mathematics; but, if you don’t like metaphor, then this is probably a good time to return the book and ask for a refund.
Deutschland in Grün by Frank Uekötter - PDF
نویسندگان: خلاصه: Das grüne Deutschland hat international unterschiedliche Bewertungen erfahren. Eine freundliche Lesart betont, die Deut- schen hätten ein Niveau des ökologischen Bewusstseins erreicht, von dem sich andere Länder ruhig eine Scheibe abschneiden könnten. Eine weniger freundliche Lesart zieht lieber eine Linie zu den finsteren Kapiteln der deutschen Geschichte, und natür- lich stehen dabei die Nazis an der Spitze der Beliebtheitsskala. Oft stimmen noch nicht einmal die Fakten, und von einer Refle- xion des Gesamtzusammenhangs ist bei solchen Gelegenheiten erst recht keine Rede.6 Während das grüne Deutschland inter- nationale Anerkennung findet, ist seine Geschichte ein Stein- bruch für all jene, denen es vor allem auf eine billige Provokation ankommt.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
