Intra-household inequality and child welfare in Argentina

Are two parents and single parents allocating household resources to children in the same way? Which factors affect intra-household inequality? Do mothers re-distribute more income to children as they are more empowered? We focus on child welfare in the context of two parent and single parent families, which is relevant for policy recommendation. We model households behavior in a collective framework, which allows us to understand the rule governing the allocation process between adults and children. Using consumption data from Argentina from three consecutive expenditures surveys (1996, 2004 and 2012) we analyze intra-household behavior over three different socio-economic contexts. We estimate a collective quadratic demand system following a structural approach to identify the fraction of total household expenditure that is devoted to children and adults, exploiting the observability of assignable goods. We provide the first evidence of intra-household inequality and individual poverty levels for Argentina. Our results indicate that family structure matters in the intra-household distribution. We find a positive gender bias in expenditure when children are females for both types of families, and we document that children fare better when mothers have a higher bargaining power in the allocation process, measured by their employment status. Further, we find several features of intra-household behavior which are persistent in time.Fil: Echeverría, Lucía. Universidad Nacional de Mar del Plata.

Influence of dietary vitamin E supplementation on cholesterol oxidation and fresh colour in beef aged for 3 and 14 days

The effects of dietary vitamin E supplementation on the susceptibility to lipid oxidation and colour of the Longissimus thoracis (LT) muscle aged in vacuum packaged conditions for 3 or 14 days were studied. For this purpose, Charolais cattle were fed on a diet providing daily 60 mg (control) or 5500 mg of vitamin E per animal (supplemented) for 30 and 60 days before slaughter. Dietary vitamin E supplementation increased the liver vitamin E content, but not in the LT muscle of treated animals. The vitamin supplementation for 30 and 60 days has shown non-consistent effects in reducing cholesterol oxidation products of vacuum-packed aged meat. However, the vitamin E supplementation for 60 days was effective on Lightness stability in LT muscle during vacuum-packed ageing. Overall, from the practical standpoint, this study suggests that supranutritional supplementation up to 60 days may not increase the vitamin E content of Charolais LT muscle giving little, if any, benefits on meat colour and cholesterol oxidation. However, the present study suggests that it would be interesting to determine in which extent specific oxysterols are related to the meat colour and whether colour parameters can be useful for predicting the formation of cholesterol oxidation products along the industrial meat production chain.The effects of dietary vitamin E supplementation on the susceptibility to lipid oxidation and colour of the Longissimus thoracis (LT) muscle aged in vacuum packaged conditions for 3 or 14 days were studied.

Effect of habitat fragmentation on rural house invasion by sylvatic triatomines: A multiple landscape-scale approach

After the decrease of the relative importance of Triatoma infestans, a number of studies reported the occurrence of sylvatic triatomines dispersing actively to domestic environments in the dry western Chaco Region of Argentina. Anthropic modification of the landscape is mentioned as one of the main causes of the increase in domicile invasion. The aim of this study was to describe the occurrence and frequency of sylvatic triatomines invading rural houses, and to evaluate the effect of habitat fragmentation and other ecological factors on the invasion of rural houses in central Argentina. We hypothesized that the decrease in food sources and the loss of wild ecotopes, as a consequence of habitat fragmentation, increases the chances of triatomines invasion.The entomological data was collected by community-based vector surveillance during fieldwork carried out between 2017-2020, over 131 houses located in fourteen rural communities in the northwest of Córdoba Province (central Argentina). We use generalized linear models with binomial error distribution and logit link function to evaluate the effect of (i) the environmental anthropic disturbance in the study area, (ii) the composition and configuration of the landscape surrounding the house, (iii) the spatial arrangement of houses, (iv) and the availability of artificial refuges and domestic animals in the peridomicile. We report the occurrence of seven species of triatomines invading rural houses in the study area -T. infestans, T. guasayana, T. garciabesi, T. platensis, T. delpontei, T. breyeri and P. guentheri -. For the first time, we present evidence suggesting thatinvasion of sylvatic triatomines occurs with higher frequency in disturbed landscapes, with houses spatially isolated and in proximity to subdivided fragments of forest. The availability of domestic refuges in the peridomestic structures as well as the presence of a higher number of domestic animals increase the chances of triatomines invasion.Fil: Cardozo, Miriam.

Reliability-oriented resource management for High-Performance Computing

Reliability is an increasingly pressing issue for High-Performance Computing systems, as failures are a threat to large-scale applications, for which an even single run may incur significant energy and billing costs. Currently, application developers need to address reliability explicitly, by integrating application-specific checkpoint/restore mechanisms. However, the application alone cannot exploit system knowledge, which is not the case for system-wide resource management systems. In this paper, we propose a reliability-oriented policy that can increase significantly component reliability by combining checkpoint/restore mechanisms exploitation and proactive resource management policies

The development of short food supply chain for locally produced honey. Understanding consumers' opinions and willingness to pay in Argentina

Purpose: The development of the short food supply chain (SFSC) is one of the issues of the current agri-food systems. Consumers are re-connecting the food they eat with the farming process and are increasingly asking for fresh, seasonal and traceable food products from known producer source. The purpose of this paper is to analyse consumers' opinions towards the SFSC and willingness to pay (WTP) for local honeys in Mar del Plata, Argentina before and after a hedonic evaluation test. Design/methodology/approach: In an incentive compatible approach, using real purchasing scenarios, two non-hypothetical discrete choice experiments were applied, accounting for the impact of the SFSC understanding and hedonic evaluation on consumers' WTP. Findings: Results showed that consumers' WTP, a premium for local honey products, is conditioned to specific quality cues and the global sensory acceptance. Consumers with high level of agreement with the social and environmental roles of the SFSC were more quality demanding and exhibited higher WTP towards the locally produced honeys. The development of local market by re-connecting producers and consumers, allowing for in-site tasting, has a strong implication for the structure of the honey added-value chain due to the potential role that may play in satisfying consumers' preference and needs. Originality/value: The authors measured consumers' opinions towards the SFSC and analyse their impact on consumer WTP for honey product by including real purchasing scenarios and hedonic evaluation test, to reduce the hypothetical bias of the traditional surveys. Questionnaires were completed in a controlled laboratory environment for with real product and real money.Fil: Kallas, Zein. Centre for Research in Agro-Food Economics and Development (CREDA).

Autoantibody Response to Islet Transplantation in Type 1 Diabetes

Islet allotransplantation into patients with autoimmune type 1 diabetes represents a reexposure to autoantigen. Here, measurement of antibodies to GAD and IA-2 autoantigens before and after islet transplantation in 36 patients (33 receiving islet plus kidney grafts with cyclosporin and steroid-based immunosuppression, and 3 receiving solitary islet transplants with mycophenolate but cyclosporin-free immunosuppression) demonstrated marked rises in GAD antibodies within 7 days posttransplantation in 5 patients (3 receiving islet after kidney transplants, and 2 receiving solitary islet transplants) and within 30 days in the third patient receiving solitary islet transplantation. GAD antibodies were of the IgG1 subclass, against major autoantigenic epitopes, and in cases of islet after kidney transplants, the responses were short-lived and not accompanied by HLA antibodies. Two of these patients had subsequent marked rises of IA-2 antibodies, and an additional patient had a marked rise in IgM-GAD antibodies 3 years after transplantation. Insulin independence was not achieved in patients with autoantibody elevations and was significantly less frequent in these patients. These data are consistent with a reactivation of autoimmunity that may be dependent on immunosuppression therapy and is associated with impaired graft function
