Sectoral allocation by gender of Latin American workers over the liberalization period of the 1990s
Get PDFThe recent restructuring of Latin American economies has renewed interest in the effects of trade liberalization, on labor markets, and on the gender division of labor. The author does not attempt to establish casuality between economic reforms, and the types of jobs that men and women hold. Instead, she provides a detailed description of the trends in male, and female formal, and informal sector participation during the economic reform period in Argentina, Brazil, and Costa Rica. The author first compares the gender composition of the formal, informal wage, and self-employment sectors in a year before reforms (1988 for Argentina, 1989 for Brazil, and Costa Rica), and a year after reforms implementation (1997 for Argentina, 1995 for Brazil and Costa Rica). Although women continued to be more likely than men to work in the informal wage sector, there is no trend of"masculinization"or"feminization"of the informal sector, or any other. Instead, in Argentina men have overtaken women as the most prevalent workers in the informal wage sector, while in Brazil, the opposite has occurred (as men move into self-employment). In Costa Rica there have been no statistical, observable changes. The author then considers the distribution across sectors within each gender group, to identify whether men, and women are more likely to select different sectors in the post-reform period relative to the pre-reform period. Among both men, and women in all three countries (except Brazilian men), workers have become more likely to hold informal wage jobs, and less likely to hold formal sector jobs. Trends in human capital accumulation explain these changes for both men, and women, while changes in gender roles, primarily in homecare and marriage, do not seem to have an effect.Health Monitoring&Evaluation,Labor Policies,Population&Development,Public Health Promotion,Environmental Economics&Policies,Health Monitoring&Evaluation,Environmental Economics&Policies,Population&Development,Banks&Banking Reform,Work&Working Conditions
RRS Discovery Cruise D334, 27 Oct-24 Nov 2008. RAPID Mooring Cruise Report
Get PDFThis report describes the mooring and underway operations conducted during RRS Discovery cruise D334 between 27 October and 24 November 2008. These mooring operations were completed as a part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5°N. The primary purpose of this cruise was to service the Eastern Boundary and Mid-Atlantic Ridge sections of the 26.5°N mooring array first deployed during RRS Discovery cruises D277 and D278 (SOC cruise report number 53), and serviced in 2005 during RRS Charles Darwin cruise CD177 (NOCS cruise report number 5), in 2006 on RRS Discovery cruise D304 (NOCS cruise report number 16) and FS Poseidon cruises P343 and P345 (NOCS cruise report number 28) and in 2007 on RRS Discovery cruise D324 (NOCS cruise report number 34). Cruise D334 started and finished in Tenerife, Spain and covered the Eastern Boundary and Mid-Atlantic Ridge moorings deployed on D324 and P343. This cruise was the fourth annual refurbishment of the Eastern Boundary and Mid-Atlantic Ridge sections of the mooring array. The array will be further refined and refurbished during subsequent years. The instruments deployed consist of a variety of current meters, bottom pressure recorders, CTD loggers and Inverted Echosounders, which, combined with time series measurements of the Florida Straits current and wind stress estimates, will be used to determine the strength and structure of the MOC at 26.5°N.

The design of advanced aircraft structures to resist acoustic fatigue; work in progress
No full textDetails of the current research activities in the Department of Aeronautics and Astronautics, on the response of advanced aircraft structures to acoustic loading, are presented. Both box type and sandwich structures, employing aluminium alloy, carbon fibre reinforced plastic, and GLARE composite materials, are being investigated. In order to develop design guidelines for these complex structures, it is necessary to combine theoretical predictions, using the finite element method, with experimental measurements of the structural response to random acoustic loading. Both types of structure will be tested in the Progressive Wave Tube facility at Southampton. In addition, it is hoped that a more comprehensive damping guide will be produced for the type of structure used in advanced aircraft design
Developing agent interaction protocols graphically and logically
No full textAlthough interaction protocols are often part of multi-agent infrastructures, many of the published protocols are semi-formal, vague or contain errors. Formal presentations can counter such disadvantages since they are amenable to verification of correctness. On the other hand, a diagrammatic representation of system structure is easier to comprehend. To this end, this paper bridges the gap between formal specification and intuitive development by: (1) proposing an extended form of propositional dynamic logic for expressing protocols completely, with clear semantics, that can be converted to a programming language for interaction protocols and (2) developing extended statecharts as a diagrammatic counterpart
Multi-view clustering for mining heterogeneous social network data
No full textPaper presented at the Workshop on Information Retrieval over Social Networks, 31st European Conference on Information Retrieval (ECIR'09), Toulouse, France, April 6-9, 2009Uncovering community structure is a core challenge in social network analysis. This is a significant challenge for large networks where there is a single type of relation in the network (e.g. friend or knows). In practice there may be other types of relation, for instance demographic or geographic information, that also reveal network structure. Uncovering structure in such multi-relational networks presents a greater challenge due to the difficulty of integrating information from different, often discordant views. In this paper we describe a system for performing cluster analysis on heterogeneous multi-view data, and present an analysis of the research themes in a bibliographic literature network, based on the integration of both co-citation links and text similarity relationships between papers in the network.Science Foundation IrelandConference detailshttp://ecir09.irit.fr/access.ph
RRS Discovery Cruise D324, 06 Oct-09 Nov 2007. RAPID Mooring Cruise Report
Get PDFThis report describes the mooring operations and underway measurements conducted during RRS Discovery Cruise D324 conducted between 6th October 2007 and 9th November 2007. This cruise was completed as part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. The primary purpose of this cruise was to service the Eastern Boundary and Mid-Atlantic ridge sections of the 26.5ºN mooring array. The array was first deployed in 2004 during RRS Discovery cruises D277 and D278 (SOC cruise report number 53), and serviced in 2005 during RRS Charles Darwin Cruise CD170 and RV Knorr Cruise KN182-2 (NOCS cruise report number 2), RRS Charles Darwin Cruise CD177 (NOCS cruise report number 5), in 2006 on RV Ronald H. Brown Cruise RB0602, RRS Discovery Cruise D304 (NOCS cruise report number 16) and FS Poseidon Cruises P343 and P345 (NOCS cruise report number 28), and in 2007 on RV Ronald H. Brown Cruise RB0701 (NOCS cruise report number 29). Cruise D324 had two legs with the first a transit from Falmouth, UK to Santa Cruz de Tenerife, Tenerife and the second sailing from, and returning to, Santa Cruz de Tenerife, Tenerife. The moorings serviced on this cruise were deployed on D304, P343 and P345, along with two landers deployed on CD170. The Rapid-MOC array of moorings was deployed across the Atlantic to set up a pre- operational prototype system to continuously observe the Atlantic Meridional Overturning Circulation (MOC). This array will be further refined and refurbished during subsequent years as part of the Rapid-WATCH programme. The instrumentation deployed on the array consists of a variety of CTD loggers, current meters, bottom pressure recorders, and Inverted Echo-sounders, which, combined with time series measurements of the Florida Current and wind stress estimates, can be used to determine the strength and structure of the MOC at 26.5ºN
RRS Charles Darwin Cruise CD177, 12-29 Nov 2005. RAPID Mooring Cruise Report
Get PDFThis report describes mooring operations and underway measurements conducted during RRS Charles Darwin Cruise CD177. Cruise CD177 was conducted between 12 November 2005 and 29 November 2005. The first part of the cruise consisted of a transit from Falmouth, UK to Santa Cruz de Tenerife, Tenerife with mooring preparation conducted on this leg. Further scientific staff joined in Santa Cruz de Tenerife for the second leg that started on the 19 November. The cruise finished in Tenerife on the 29 November.This cruise was completed as part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. The primary purposes of this cruise were to service the two key moorings (EB1 and EB2) on the eastern boundary of the 26.5ºN mooring array and to deploy two Pressure Inverted Echosounders (PIES). The array was first deployed in 2004 during RRS Discovery cruises D277 and D278 (Southampton Oceanography Centre Cruise Report No. 53) in order to set up a pre-operational prototype system to continuously observe the Atlantic Meridional Overturning Circulation (MOC). It was subsequently serviced on RRS Charles Darwin cruise CD170 and RV Knorr cruise KN182-2 (both covered in National Oceanography Centre Southampton Cruise Report No. 2). The array will be further refined and refurbished during subsequent years.This cruise was planned in response to mooring losses suffered in the first year of the 26.5ºN array deployment. The two key eastern boundary moorings were subjected to damage through suspected fishing activity causing the loss of data above 1200m at the eastern boundary. To reduce the risk of data loss we plan to service the two key moorings on a six-monthly cycle.Instruments deployed on the array consists of a variety of current meters, bottom pressure recorders and CTD loggers which, combined with time series measurements of the Florida Channel Current and wind stress estimates, will be used to determine the strength and structure of the MOC at 26.5ºN.

A propósito de un eslabón perdido: la (re)aparición de Assemblage (Merce Cunningham, Richard Moore, 1968)
Get PDFLargamente olvidada entre otros materiales, la película Assemblage ha sido recientemente redescubierta, restaurada y presentada en diversas premieres en los Estados Unidos. En 1968 Merce Cunningham tiene la oportunidad de crear una pieza audiovisual en colaboración con el poeta y director de cine experimental Richard O. Moore, y la estación KQED de San Francisco. Assemblage se filma en Ghirardelli Square, un nuevo espacio público a medio camino entre el mall comercial y la plaza pública. Cunningham concibe su coreografía precisamente desde esta idea de intervención en un espacio público. Todo el metraje filmado con varias cámaras se procesaría después en la sala de montaje, utilizando todos los recursos característicos del cine experimental, y abre así el camino a una nueva concepción del cine de danza.; Long forgotten among other materials , the film Assemblage was recently rediscovered, restored and presented in several premieres in the United States. In 1968 Merce Cunningham have the opportunity to create a filmed choreography in collaboration with the poet and experimental filmmaker Richard O. Moore, and the station KQED in San Francisco. Assemblage is filmed in Ghirardelli Square, a new public space midway between the commercial mall and public square. Cunningham sees his choreography precisely from this idea of intervention in a public space. All the footage filmed with multiple cameras will be processed later in the editing room, using all the resources characteristic of experimental film, and thus opens the way to a new conception of screendance
Caracterización de la comunidad vegetal en una asociación de gramíneas mejoradas y Leucaena leucocephala cv.: Cunningham Characterization of the plant community in an association of improved grasses and Leucaena leucocephala cv.: Cunningham
No full textEn una vaquería de la Empresa Genética de Matanzas se realizó un estudio durante cinco años, con el objetivo de caracterizar el comportamiento de la comunidad vegetal en una asociación de gramíneas mejoradas y Leucaena leucocephala cv. Cunningham en condiciones comerciales. Se determinó la composición botánica del pastizal, la densidad de arbóreas, la disponibilidad de materia seca y los contenidos de MS, PB, Ca y P de las especies presentes en el sistema. La composición botánica del pastizal se caracterizó por un porcentaje de pastos mejorados superior al 50%, con predominio de Cynodon nlemfuensis cv. Jamaicano y Panicum maximum cv. Likoni; mientras que la leucaena mantuvo la densidad de plantas, como una adaptación a las condiciones del sistema. La disponibilidad de materia seca total fue superior a las 3 t/ha/rotación durante la etapa experimental. Se concluye que en la asociación de gramíneas mejoradas y L. leucocephala cv. Cunningham se presentó una alta disponibilidad de materia seca y persistencia del pastizal durante los cinco años del estudio, con valores de PB en las gramíneas mejoradas de 9,6-9,8% y en la leucaena de 25%, sin la aplicación de riego ni fertilizantes químicos, lo cual permitió atenuar las diferencias entre los períodos lluvioso y poco lluvioso.In a dairy of the Genetic Enterprise of Matanzas, a work was carried out for five years, with the objective of characterizing the performance of the plant community in an association of improved grasses and Leucaena leucocephala cv Cunningham under commercial conditions.
