The political economy of formal sector pay and employment in developing countries

Domestic labor market outcomes influence the direction and magnitude of the flow of international migration. When wages are low and jobs are scarce, workers tend to migrate to environments where jobs are available at higher wages. But as labor demand grows, a labor-exporting country may become a net labor importer. Such a"migration transition"- already much in evidence in East and Southeast Asian countries and beginning for skilled workers in India - is analogous to the demographic transition. The process of political economy described by the authors affects the level and growth of wages and of formal sector emmployment. So it is important for policymakers concerned about migration to high-income countries to take it into account. An efficient, flexible, responsive labormarket contributes to growth by creating an appropriate economic environment. In this respect, labor policy is like macroeconomic and trade policy. Unlike the accumulation of physical and human capital and technical progress, a well-functioning labor market is not itself a source of economic growth. Yet labor market pathologies, like macroeconomic mismanagement, can be extremely costly, severely constraining growth of output and employment and increasing inequality. Similarly, failure to adequately address the labor-market aspects of policy reform can result in the failure of other dimensions of reform. The smooth functioning of the labor market feeds on itself, enhancing the credibility of both workers and the elite. Conversely, poor labor market performance can also be self-reinforcing. Attempts to reform the labor market feeds on itself, enhancing the credibility of both workers and the elite. The payoff on labor reform can be high for both groups. The challenge is to find mechanisms whereby the credibility of both groups can be bolstered.Labor Policies,Environmental Economics&Policies,Banks&Banking Reform,Municipal Financial Management,Health Economics&Finance,Environmental Economics&Policies,Banks&Banking Reform,Municipal Financial Management,Health Economics&Finance,Labor Standards

Temporal and thermal evolution of extensional faulting in the central Gulf of Suez and detrital zircon (U-Th)/He constraints on the thermo-tectonic Paleozoic and Mesozoic history of the Sinai, Egypt

Many fundamental concepts of rifting have been influenced by observation made in the Gulf of Suez as a result of detailed structural and sedimentological studies. Although the three-dimensional structural geometry of the rift is well understood, the timing of faulting, the nature of faults linkage during progressive rifting and the influence on syn-rift sedimentation is poorly constrained. Despite ample fission track data from the Sinai rift flank, the lack of thermochronometric data from exhumed pre-rift sedimentary cover and crystalline basement blocks in a proper structural context within the rift limit the temporal and thermal reconstruction and the influence of pre-rift structures on the style of rifting. To elucidate the temporal and spatial evolution of extensional faulting and fault interaction in the central Gulf of Suez, this study presents new apatite (U-Th)/He (AHe) thermochronometric data from vertical transects and combines both surface and borehole sample arrays from normal fault blocks, integrated with structural block reconstruction of the central east margin of the Gulf of Suez. AHe data from the Sinai border fault complex at Gebel Samra (north) and Gebel Mutga (south) and surface and subsurface samples from the Hamman Faraun fault blocks explore the temporal progression of normal faulting and the evolution of fault hard linkage in the central Gulf of Suez in the early to middle Miocene after the onset of normal faulting at ~23 Ma. As a second aspect, zircon (U-Th)/He (ZHe) dating from pre-rift strata and basement samples were analyzed to better constrain the pre-Tertiary tectonic, detrital provenance and thermal evolution of the Gulf of Suez to shed light on the Paleozoic/Mesozoic tectonic evolution and its influence on Red Sea-Gulf of Suez rifting. ZHe data from pre-rift strata in the central Gulf of Suez record a detailed Paleozoic/Mesozoic tectonic history that is highly influenced by Carboniferous, Triassic/Jurassic, and Santonian tectonism. Carboniferous Abu Thora sandstone contain detrital ZHe ages that suggest very short lag time, indicative of late Paleozoic tectonism and rapid cooling. Similarly, Triassic Qiseib sandstones, exhibits detrital ZHe ages indistinguishable from its stratigraphic age, underlining the importance of Triassic/Jurassic Neo-Tethyan rifting. Cretaceous Matulla pre-rift sandstones are dominated by Santonian detrital ZHe ages, with very short lag times, associated with the Syrian arc inverted structures and folding. The combination of AHe and ZHe ages in a detailed stratigraphic and structural context elucidates both the Neogene Gulf of Suez rift evolution and the impact of Paleozoic/Mesozoic tectonism on the structural grain of the gulf allowing for a more detailed and spatially differentiated understanding of the timing of extensional faulting and nature of fault linkage during progressive early to middle Miocene rifting in the central Gulf of Suez

Mammalia, Didelphimorphia and Rodentia, southwest of the province of Mendoza, Argentina

We documented terrestrial micromammal assemblages at five localities of southwestern Mendoza province, Argentina. We added new localities for several of the most uncommon small mammal species of this region (e.g. Loxodontomys micropus and Tympanoctomys barrerae). Two main groups of terrestrial non-volant micromammals are represented in southwestern province of Mendoza: one group is related to the South American arid diagonal, and includes species typically adapted to the xeric environments of the Monte Desert; a second group includes Patagonian and High Andean species. Some Patagonian species reached in the study area their northernmost distributional records (e.g. Abrothrix longipilis, A. olivaceus, Chelemys macronyx, Loxodontomys micropus).Fil: Pardiñas, Ulises Francisco J..

Prospective observational study of point-of-care creatinine in trauma.

Background:Patients with trauma are at risk for renal dysfunction from hypovolemia or urological injury. In austere environments, creatinine values are not available to guide resuscitation. A new portable device, the Stat Sensor Point-of-care (POC) Whole Blood Creatinine Analyzer, provides accurate results in <30 s and requires minimal training. This device has not been evaluated in trauma despite the theoretical benefit it provides. The purpose of this study is to determine the clinical impact of the POC device in trauma. Methods:40 patients with trauma were enrolled in a prospective observational study. One drop of blood was used for creatinine determination on the Statsensor POC device. POC creatinine results were compared to the laboratory. Turnaround time (TAT) for POC and laboratory methods was calculated as well as time elapsed to CT scan if applicable. Results:Patients (n=40) were enrolled between December 2014 and March 2015. POC creatinine values were similar to laboratory methods with a mean bias of 0.075±0.27 (p=0.08). Mean analytical TATs for the POC measurements were significantly faster than the laboratory method (11.6±10.0 min vs 78.1±27.9 min, n=40, p<0.0001). Mean elapsed time before arrival at the CT scanner was 52.9±34.2 min. Conclusions:The POC device reported similar creatinine values to the laboratory and provided significantly faster results. POC creatinine testing is a promising development for trauma practice in austere environments and workup of a subset of stable patients with trauma. Further study is warranted to determine clinical impact, both in hospital-based trauma and austere environments

Biopreservation of hepatocytes: current concepts on hypothermic preservation, cryopreservation, and vitrification

Isolated liver cells (primarily isolated hepatocytes) have found important applications in science and medicine over the past 40 years in a wide range of areas, including physiological studies, investigations on liver metabolism, organ preservation and drug de-toxification, experimental and clinical transplantation. An integral component of many of these works is the need to store the isolated cells, either for short or long-term periods. This review covers the biopreservation of liver cells, with a focus on the history of liver cell biopreservation, the application of hypothermia for short-term storage, standard cryopreservation methods for isolated hepatocytes, the biopreservation of other types of liver cells, and recent developments such as vitrification of hepatocytes. By understanding the basis for the different approaches, it will be possible to select the best options for liver cell biopreservation in different applications, and identify ways to improve preservation protocols for the future.Fil: Fuller, Barry J..

Properties of the open cluster Tombaugh 1 from high resolution spectroscopy and uvbyCaHβ\beta photometry

Open clusters can be the key to deepen our knowledge on various issues involving the structure and evolution of the Galactic disk and details of stellar evolution because a cluster's properties are applicable to all its members. However the number of open clusters with detailed analysis from high resolution spectroscopy and/or precision photometry imposes severe limitation on studies of these objects. To expand the number of open clusters with well-defined chemical abundances and fundamental parameters, we investigate the poorly studied, anticenter open cluster Tombaugh 1. Using precision uvbyCaH$\beta$ photometry and high resolution spectroscopy, we derive the cluster's properties and, for the first time, present detailed abundance analysis of 10 potential cluster stars. Using radial position from the cluster center and multiple color indices, we have isolated a sample of unevolved probable, single-star members of Tombaugh 1. The weighted photometric metallicity from $m_1$ and $hk$ is [Fe/H] = -0.10 $\pm$ 0.02, while a match to the Victoria-Regina Str\"{o}mgren isochrones leads to an age of 0.95 $\pm$ 0.10 Gyr and an apparent modulus of $(m-M)$ = 13.10 $\pm$ 0.10. Radial velocities identify 6 giants as probable cluster members and the elemental abundances of Fe, Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Y,Ba, Ce, and Nd have been derived for both the cluster and the field stars. Tombaugh 1 appears to be a typical inner thin disk, intermediate-age open cluster of slightly subsolar metallicity, located just beyond the solar circle, with solar elemental abundance ratios except for the heavy s-process elements, which are a factor of two above solar. Its metallicity is consistent with a steep metallicity gradient in the galactocentric region between 9.5 and 12 kpc. Our study also shows that Cepheid XZ CMa is not a member of Tombaugh 1, and reveals that this Cepheid presents signs of barium enrichment.Comment: 74 pages, 15 figures, 13 tables; Accepted for publication in A
