Night-Time Stories from The Panchatantra
No full textSimilar to Arora's 101 Moral Stories of Grandpa, this hardbound book with dust-jacket has 100 pages. The T of C on 6 lists fifteen numbered stories. This book is remarkable for offering a large picture on almost every page. New to me is The Sparrows & the Tusker (51). An elephant breaks off a limb and unwittingly destroys a nest. The sparrows get help from a woodpecker, a fly, and a frog, Together they lull the elephant, blind him by pecking out his eyes, and mislead him into a deep pit he mistakes for a water-hole. It is nice to meet old friends from the Panchatantra and Kalila and Dimna tradition, and I enjoy Ram-Lakshman's art. One of the best images here is that of the lion springing into the well as the hare runs away (99).

In the present study, the cytotoxic effect of the triazole ipconazole was evaluated in porcine and ram spermatozoa. Ipconazole significantly reduced sperm viability, increased ROS levels, altered catalase and SOD enzyme activity, and caused alterations in the molecular mRNA expression of structural biomarkers (PRM1, ODF2, AKAP4, THEG, SPACA3 and CLGN) related to fertility in males, as well as the overexpression of BAX (cell death) and ROMO1 (oxidative stress) mRNA. Our results indicate that the fungicide triazole is involved in cellular, enzymatic and molecular alteration of porcine and ram spermatozoa, and is possibly a factor in the development of infertility in male mammalsNational University of San Marcos (Italia)Depto. de Farmacología y ToxicologíaFac. de VeterinariaTRUEpu
Revolutionary Action Movement (RAM): a case study of an urban revolutionary movement in western capitalist society, 1986
Get PDFThe primary intent of this thesis is to present a political descriptive analysis of the Revolutionary Action Movement (RAM), and urban revolutionary movement active in the 1960's. An attempt has been made to portray the historical context, the organization, ideology of the RAM organization and response of the state to the activities of the organization. The thesis presents a methodological approach to developing a paradigm in which the study of urban revolutionary movements is part of a rational analysis. The thesis also explains concepts and theories that are presented later in the text. A review of black radical activity from 1900 to 1960 is given to provide the reader with historical background information of the events and personalities which contributed to the development of RAM. A comparative analysis is made between urban revolutionary movements in Latin America and the United States in order to show that the RAM organization was part of a worldwide urban phenomenon. The scope of the thesis is to present an analysis of the birth, early beginnings of RAM as a national organization, and Malcolm X's impact on the organization. The thesis also covers RAM's organizational activities in two phases, including the dissolution of the organization. The basic tenets of RAM's ideology are examined in the thesis along with an analysis of repression waged against the organization by governmental intelligence agencies. The thesis concludes with a critical analysis of RAM as an organizational model in the black freedom struggle
Evaluation of the Bioinformatic tool RAM and Diversification of Carollia perspicillata and C. brevicauda (Chiroptera: Phyllostomidae)
No full textCarollia species are commonly found in the Neotropic region. Their ancestral origins have been subject to debate. To shed light on their evolutionary history in the context of the Andean orogeny, this study employed a dual-pronged approach. It combined the use of RepeatAfterMe (RAM), a newly developed bioinformatics tool for enhanced Transposable Element (TE) family identification, with phylogenetic, divergence, and biogeographical analyses. RAM was used to identify 513 TE consensus sequences, with 349 classified as "complete." This tool accelerated the analysis compared to manual curation methods and demonstrated exceptional accuracy, requiring minimal manual intervention. Interestingly, RAM uncovered previously uncharacterized TE diversity, as distinct species-specific Ves SINE subfamilies were identified in C. perspicillata, despite reduced recent TE accumulation. Phylogenetic analyses supported the distinct clades within both C. brevicauda and C. perspicillata. The study estimated that the most recent common ancestor (MRCA) of both species lived in the Brazilian Amazon rainforest approximately 3.13 million years ago (Ma), with a minimal probability of 0.0314, supporting a shared South American ancestry. The divergence times of C. brevicauda (2.05 Ma) and C. perspicillata (2.04 Ma) closely align with the uplift of the northern Andes (5 Ma to present), potentially illuminating the dispersal events experienced by these species.Embargo status: Restricted until 01/2027.

Great Expectatrics: Great Papers, Great Journals, Great Econometrics
Get PDFThe paper discusses alternative Research Assessment Measures (RAM), with an emphasis on the Thomson Reuters ISI Web of Science database (hereafter ISI). The various ISI RAM that are calculated annually or updated daily are defined and analysed, including the classic 2-year impact factor (2YIF), 5-year impact factor (5YIF), Immediacy (or zero-year impact factor (0YIF)), Eigenfactor score, Article Influence, C3PO (Citation Performance Per Paper Online), h-index, Zinfluence, and PI-BETA (Papers Ignored - By Even The Authors). The ISI RAM data are analysed for 8 leading econometrics journals and 4 leading statistics journals. The application to econometrics can be used as a template for other areas in economics, for other scientific disciplines, and as a benchmark for newer journals in a range of disciplines. In addition to evaluating high quality research in leading econometrics journals, the paper also compares econometrics and statistics, alternative RAM, highlights the similarities and differences in alternative RAM criteria, finds that several ISI RAM capture similar performance characteristics for the leading econometrics and statistics journals while the new PI-BETA criterion is not highly correlated with any of the other ISI RAM, and hence conveys additional information regarding ISI RAM, highlights major research areas in leading journals in econometrics, and discusses some likely future uses of RAM.Research assessment measures, impact factors, Immediacy, Eigenfactor score, Article influence, h-index, C3PO, Zinfluence, PI-BETA

Pension reform in Latin America : quick fixes or sustainable reform?
Get PDFBecause of better health and higher standards of living, people are living longer. By 2030, more than 16 percent of the world's population will be older than 60, compared with 9 percent today. As a result, pension systems will need reform. Most current systems have substantial unfunded liabilities that will impose significant financial burdens onfuture generations without providing adequate protection for older individuals and lower-income workers. Pension reform is inevitable because of demographic imperatives and because many pension systems are financially unsustainable. Unfunded public pension systems pose political risk if promises to future retirees cannot be met. Pension reform is both technically and politically complex but more and more countries are beginning to address the problem. The question is whether to adopt quick fixes or sustainable changes that will benefit the macroeconomy and protect elderly and lower-income citizens. Quick fixes--typical in many economies--generally involve changes in eligibility (such as retirement age), changes in the rate of contribution or the population of workers on which contributions are calculated, or changes in the structure of benefits. Countries in Latin America have been ahead of other regions in undertaking major reform from pay-as-you-go defined-benefit pension plans to fully funded, defined-contribution pension plans. Because of the successful Chilean pension model, a notable number of Latin American countries have undertaken deep pension reform. The author highlights reform efforts in a sample of countries: Argentina, Brazil, Chile, Mexico, and Peru. Vigilance is still needed, says the author. Effective oversight is essential, and so is complementary reform in the banking, insurance, and securities markets. In capital markets, for example, regulation must be strengthened and the requirement that pension fund investments be made only in government-related securities must be eliminated. New types of insurance must be made available and there must be increased competition among insurance providers. More work must be done but the region's pension systems have started on the right course.Banks&Banking Reform,Payment Systems&Infrastructure,Public Health Promotion,Pensions&Retirement Systems,Environmental Economics&Policies,Pensions&Retirement Systems,Economic Stabilization,Banks&Banking Reform,Environmental Economics&Policies,Economic Theory&Research

The Statistical Reader: The Role of Orthographic Regularities in Reading
Get PDFAvailable online 14 April 2025Recent statistical learning views of reading posit that writing systems present to their readers a wide range of statistical regularities which are leveraged to process printed texts. While substantial research has focused on the “vertical” correlations between orthographic, phonological, and semantic units in a given writing system, here we employ information-theoretic measures to further consider “horizontal” regularities—the extent to which printed units predict and are predicted by other printed units, in one writing system compared to another. As a first step, we present a novel information-theoretic measure that captures how horizontal regularities constrain lexical access given the distribution of orthographic information in a writing system and considering realistic retinal and cognitive constraints. We then present a series of empirical studies serving as proof of concept, from both single-word reading experiments and analyses of eye movements during naturalistic reading, which examine how a reader who has internalized these regularities could leverage them for efficient uncertainty reduction regarding printed information while reading on-the-fly. Our findings converge on high-order general principles fleshed out in terms of explicit computational mechanisms that simultaneously apply to a wide range of writing systems and that can potentially explain behavioral outcomes across the trajectory of reading development and reading skill.
