Between ideal and transgression: Female honor in Chile 1800 - 1825
Indexación: Revista UNABEn la siguiente investigación se aborda el tratamiento del honor femenino durante 1800 hasta 1852, a través de la revisión de procesos judiciales en los que estuviese, al menos, una mujer involucrada. Analizada desde los ideales y de su trasgresión por medio del insulto-palabra se construye el honor de un naciente grupo medio y del bajo pueblo. El trabajo plantea que el honor se basó en la reputación y fama pública que tuvieron las personas ante su comunidad y no discriminó por género, a pesar de construirse en el marco de una sociedad patriarcal. Las mujeres de la primera mitad del siglo XIX se sintieron sujetos portadores de honor, el que fue resignificado desde la realidad vivencial de cada mujer, llegando a ser el honor sexual el más cuidado y a la vez el más vulnerado de la época.The following research addresses the concept of female honor through the study of court processes during 1800-1852 where at least one woman is involved. The honor of a nascent middle group and low people can be determined by means of analyzing the ideals and their transgressions through insults. This article suggests that honor was based on public reputation without taking gender into account, despite the context of a patriarchal society: during the first half of the XIX century, women considered themselves subjects worthy of honor, which was resignified from the experience of each woman, becoming sexual honor the most essential and, at the same time, injured of the time.http://revistahumanidades.unab.cl/numero-22
Stability through cycles
Economic variables like GDP growth, employment, interest rates and consumption show signs of cyclical behavior. Many variables display multiple cycles, with lengths ranging in between 5 to even up to 100 years. We argue that multiple cycles can be associated with long-run stability of the economic system, provided that the cycle lengths are such that interference is rare or absent. For a large sample of important variables, including key variables for the US, UK and the Netherlands, we document that this is indeed the case.business cycles;Fibonacci;long waves;economic stability
Modelling and Forecasting Volatility of Returns on the Ghana Stock Exchange Using GARCH Models
This paper models and forecasts volatility (conditional variance) on the Ghana Stock Exchange using a random walk (RW), GARCH(1,1), EGARCH(1,1), and TGARCH(1,1) models. The unique ‘three days a week’ Databank Stock Index (DSI) is used to study the dynamics of the Ghana stock market volatility over a 10-year period. The competing volatility models were estimated and their specification and forecast performance compared with each other, using AIC and LL information criteria and BDS nonlinearity diagnostic checks. The DSI exhibits the stylized characteristics such as volatility clustering, leptokurtosis and asymmetry effects associated with stock market returns on more advanced stock markets. The random walk hypothesis is rejected for the DSI. Overall, the GARCH (1,1) model outperformed the other models under the assumption that the innovations follow a normal distribution.Ghana Stock Exchange; developing financial markets; volatility; GARCH model
Is the UK productivity slowdown unprecedented?
We estimate trend UK labour productivity growth using a Hodrick-Prescott filter method. We use the results to compare downturns where the economy fell below its pre-existing trend. We find that the current productivity slowdown has resulted in productivity being 19.7 per cent below the pre-2008 trend path in 2018. This is nearly double the previous worst productivity shortfall ten years after the start of a downturn. On this criterion the slowdown is unprecedented in the past 250 years. We conjecture that this reflects a combination of adverse circumstances, namely, a financial crisis, a weakening impact of ICT and impending Brexit
Cycles in basic innovations
Basic innovations are often believed to be the drivers of economic growth. It has been widely documented that economic growth follows cyclical patterns of varying length. In this paper we examine if such patterns are also present in basic innovations. For an annual time series of count data covering 1764-1976, we fit a harmonic Poisson regression model. The results suggest the presence of multiple cycles of length 5, 13, 24, 34 and 61. We compare these cycles and their joint effect with widely documented economic cycles and find important resemblances and differences.economic cycles;basic innovations;harmonics;poisson regression
Data Mining of Online Genealogy Datasets for Revealing Lifespan Patterns in Human Population
Online genealogy datasets contain extensive information about millions of
people and their past and present family connections. This vast amount of data
can assist in identifying various patterns in human population. In this study,
we present methods and algorithms which can assist in identifying variations in
lifespan distributions of human population in the past centuries, in detecting
social and genetic features which correlate with human lifespan, and in
constructing predictive models of human lifespan based on various features
which can easily be extracted from genealogy datasets.
We have evaluated the presented methods and algorithms on a large online
genealogy dataset with over a million profiles and over 9 million connections,
all of which were collected from the WikiTree website. Our findings indicate
that significant but small positive correlations exist between the parents'
lifespan and their children's lifespan. Additionally, we found slightly higher
and significant correlations between the lifespans of spouses. We also
discovered a very small positive and significant correlation between longevity
and reproductive success in males, and a small and significant negative
correlation between longevity and reproductive success in females. Moreover,
our machine learning algorithms presented better than random classification
results in predicting which people who outlive the age of 50 will also outlive
the age of 80.
We believe that this study will be the first of many studies which utilize
the wealth of data on human populations, existing in online genealogy datasets,
to better understand factors which influence human lifespan. Understanding
these factors can assist scientists in providing solutions for successful
aging
The EROS2 search for microlensing events towards the spiral arms: the complete seven season results
The EROS-2 project has been designed to search for microlensing events
towards any dense stellar field. The densest parts of the Galactic spiral arms
have been monitored to maximize the microlensing signal expected from the stars
of the Galactic disk and bulge. 12.9 million stars have been monitored during 7
seasons towards 4 directions in the Galactic plane, away from the Galactic
center. A total of 27 microlensing event candidates have been found. Estimates
of the optical depths from the 22 best events are provided. A first order
interpretation shows that simple Galactic models with a standard disk and an
elongated bulge are in agreement with our observations. We find that the
average microlensing optical depth towards the complete EROS-cataloged stars of
the spiral arms is , a number that is
stable when the selection criteria are moderately varied. As the EROS catalog
is almost complete up to , the optical depth estimated for the
sub-sample of bright target stars with () is easier to interpret. The set of microlensing events
that we have observed is consistent with a simple Galactic model. A more
precise interpretation would require either a better knowledge of the distance
distribution of the target stars, or a simulation based on a Galactic model.
For this purpose, we define and discuss the concept of optical depth for a
given catalog or for a limiting magnitude.Comment: 22 pages submitted to Astronomy & Astrophysic
