The employment situation in Latin America and the Caribbean: Advances and challenges in measuring decent work

At 6.4%, the unemployment rate for the Latin American and Caribbean region overall was the lowest for the past few decades, down from 6.7% in 2011. This is significant, in view of the difficult employment situation prevailing in other world regions. Labour market indicators improved despite modest growth of just 3.0% in the region’s economy. Even with sharply rising labour market participation, the number of urban unemployed fell by around 400,000, on the back of relatively strong job creation. Nevertheless, around 15 million are still jobless in the region. Other highlights of 2012 labour market performance were that the gender gaps in labour market participation, unemployment and employment narrowed, albeit slightly; formal employment increased; the hourly underemployment rate declined; and average wages rose. This rendering was obviously not homogenous across the region. Labour market indicators worsened again in the Caribbean countries, for example, reflecting the sluggish performance of their economies. The sustainability of recent labour market progress is also a cause for concern. Most of the new jobs in the region were created as part of a self-perpetuating cycle in which new jobs and higher real wages (and greater access to credit) have boosted household purchasing power and so pushed up domestic demand. Much of this demand is for non-tradable goods and services (and imports), which has stimulated expansion of the tertiary sector and hence its demand for labour, and many of the new jobs have therefore arisen in these sectors of the economy. This dynamic certainly has positive implications in terms of labour and distribution, but the concern is whether it is sustainable in a context of still relatively low investment (even after some recent gains) which is, moreover, not structured in a manner conducive to diversifying production. Doubt hangs over the future growth of production capacity in the region, given the enormous challenges facing the region in terms of innovation, education quality, infrastructure and productivity. As vigorous job creation has driven progress in reducing unemployment, attention has turned once again to the characteristics of that employment. Awareness exists in the region that economic growth is essential, but not in itself sufficient to generate more and better jobs. For some time, ILO has been drawing attention to the fact that it is not enough to create any sort of employment. The concept of decent work, as proposed by ILO, emphasized the need for quality jobs which enshrine respect for fundamental rights at work. The United Nations General Assembly endorsed this notion and incorporated it into the targets set in the framework of the Millennium Development Goals. This eighth issue of the ECLAC/ILO publication “The employment situation in Latin America and the Caribbean” examines how the concept of decent work has evolved in the region, progress in measuring it and the challenges involved in building a system of decent work indicators, 14 years after the concept was first proposed. Although the concept of decent work has been accompanied since the outset by the challenge of measurement, its first objective was to generate a discussion on the best achievable labour practices in each country. Accordingly, rather than defining a universal threshold of what could be considered decent work —regarding which developed countries might have almost reached the target before starting, while poor countries could be left hopelessly behind— ILO called upon the countries to define their own criteria and measurements for promoting decent work policies. As a result, there is no shared set of variables for measuring decent work applicable to all countries. The suggestion is, instead, that countries move forward with measuring decent work on the basis of their own priorities, using the information they have available now and in the future. However, this strategy of progressing according to the data available in each country tends to complicate statistical comparison between them. So, once the countries have developed their respective systems of decent work indicators, it will be also be important to work towards harmonizing them. ECLAC and ILO are available to provide technical support to this end. With respect to 2013, there is cautious optimism regarding the performance of the region’s labour markets. If projections of a slight uptick —to 3.5%— in the region’s economic growth in 2013 are borne out, labour indicators should continue to gradually improve. This will bring new increases in real wages and a slight drop of up to 0.2 percentage points in the region’s unemployment rate, reflecting a fresh rise in the regional employment rate and slower growth in labour market participation.

New strategies for planning and performance evaluation of wireless networks: case studies based on the cross-layer approach

The use of wireless local area networks, called WLANs, as well as the proliferation of the use of multimedia applications have grown rapidly in recent years. Some factors affect the quality of service (QoS) received by the user and interference is one of them. This work presents strategies for planning and performance evaluation through an empirical study of the QoS parameters of a voice over Internet Protocol (VoIP) application in an interference network, as well as the relevance in the design of wireless networks to determine the coverage area of an access point, taking into account several parameters such as power, jitter, packet loss, delay, and PMOS. Another strategy is based on a hybrid approach that considers measuring and Bayesian inference applied to wireless networks, taking into consideration QoS parameters. The models take into account a cross layer vision of networks, correlating aspects of the physical environment, on the signal propagation (power or distance) with aspects of VoIP applications (e.g., jitter and packet loss). Case studies were carried out for two indoor environments and two outdoor environments, one of them displaying main characteristics of the Amazon region (e.g., densely arboreous environments). This last test bed was carried out in a real system because the Government of the State of Pará has a digital inclusion program called NAVEGAPARÁ.

Herivelto Brandino e a obra mensagem para marimba solo: discussão do processo composicional e performance

This article points out some elements required for comprehending the work mensagem for marimba solo (2011) by Herivelto Brandino in regard to its compositional process and performance. The text shows how various materials have been chosen for the confection of the work - mainly those related to the act of writing texts - and approaches the composer's queries about the non-necessity, and even the uselessness of composition, performance and artistic objects themselves. At the end we conclude that regardless such a supposed non-necessity of any musical object it is possible to construct a coherent piece based on similar paradoxes that, at first, served to make any compositional work useless.

Comparison of the performance of natural latex membranes prepared with different procedures and PTFE membrane in guided bone regeneration (GBR) in rabbits

This work assessed the performance of membranes made of natural latex extracted from Hevea brasiliensis prepared with three different methods: polymerized immediately after collection without the use of ammonia (L1); polymerized after preservation in ammonia solution (L2); and polymerized after storage in ammonia, followed by Soxhlet technique for the extraction of substances (L3). Polytetrafluoroethylene (PTFE) membrane was used as control. Two 10-mm diameter bone defects were surgically made in the calvaria of thirty adult male New Zealand rabbits. Defects (total n = 60) were treated with guided bone regeneration (GBR) using L1, L2, L3 or PTFE membranes (n = 15 for each membrane). Ten animals were euthanized after 7, 20 and 60 days postoperatively so that five samples (n = 5) of each treatment were collected at each time, and bone regeneration was assessed microscopically. The microscopic analysis revealed defects filled with blood clot and new bone formation at the margins of the defect in all 7-day samples, while 20-day defects were mainly filled with fibrous connective tissue. After 60 days defects covered with L1 membranes showed a significantly larger bone formation area in comparison to the other groups (P < 0.05, ANOVA, Tukey). Additionally, bone tissue hypersensitization for L1 and PTFE membranes was also investigated in six additional rabbits. The animals were subjected to the same surgical procedure for the confection of one 10-mm diameter bone defect that was treated with L1 (n = 3) or PTFE (n = 3). Fifty-three days later, a second surgery was performed to make a second defect, which was treated with the same type of membrane used in the first surgery. Seven days later, the animals were euthanized and samples analyzed. No differences among L1 and PTFE samples collected from sensitized and non-sensitized animals were found (P > 0.05, Kruskal-Wallis). Therefore, the results demonstrated that latex membranes presented performance comparable to PTFE membranes, and that L1 membranes induced higher bone formation. L1 and PTFE membranes produced no hypersensitization in the bone tissue.

Influence of inoculum on performance of anaerobic reactors for treating municipal solid waste

The influence of bovine rumen fluid inoculum during anaerobic treatment of the organic fraction of municipal solid waste (MSW) was studied in this work. The parameters adopted for evaluation were the biostabilization constant of total volatile solids (TVs) and the biostabilization time of the chemical oxygen demand (COD) applied to the reactors. The work was realized in four anaerobic batch reactors of 20 1 capacity each, during a period of 365 days. The proportions between MSW/inoculum loaded in the reactors were Reactor A (100%/0%), Reactor B (95%/5%), Reactor C (90%/10%) and Reactor D (85%/15%). The necessary time for biostabilization of half of the applied COD was 459, 347, 302 and 234 days and the average of methane concentration in the biogas produced was 3.6%, 13.0%, 25.0% and 42.6% for Reactors A, B, C and D, respectively. The data obtained affirm that the inoculum used substantially improved the performance of the process. (C) 2004 Elsevier Ltd. All rights reserved.
