Sources of familial aggregation and co-aggregation of fasting blood glucose and nutritional factors among Mexican -Americans in Starr County, Texas

The purpose of this study was to determine the effects of nutrient intake, genetic factors and common household environmental factors on the aggregation of fasting blood glucose among Mexican-Americans in Starr County, Texas. This study was designed to determine: (a) the proportion of variation of fasting blood glucose concentration explained by unmeasured genetic and common household environmental effects; (b) the degree of familial aggregation of measures of nutrient intake; and (c) the extent to which the familial aggregation of fasting blood glucose is explained by nutrient intake and its aggregation. The method of path analysis was employed to determine these various effects.^ Genes play an important role in fasting blood glucose: Genetic variation was found to explain about 40% of the total variation in fasting blood glucose. Common household environmental effects, on the other hand, explained less than 3% of the variation in fasting blood glucose levels among individuals. Common household effects, however, did have significant effects on measures of nutrient intake, though it explained only about 10% of the total variance in nutrient intake. Finally, there was significant familial aggregation of nutrient intake measures, but their aggregation did not contribute significantly to the familial aggregation of fasting blood glucose. These results imply that similarities among relatives for fasting blood glucose are not due to similarities in nutrient intake among relatives. ^

Hydrochemical and geothermic data on the Caribbean-Mexican region

Results of detailed geophysical, geological and gas- and hydrochemical research in the Caribbean-Mexican Basin and the Western Atlantic obtained during Cruise 4 of R/V Akademik Nikolaj Strakhov are published in the book. Distribution of the thermal field in different tectonic structures of the region is shown. Places of submarine hydrothermal vent discharge in tectonically active structures are described. They are confirmed by geothermal, geological and hydrochemical data. Based on lithofacies analysis of modern sediments installed their Specificity of different genetic types, facies and macrofacies of recent sediments in different geomorphological zones of the sea floor is shown. For description of hydrogeochemical situation of modern sedimentation and primary diagenesis the water column and interstitial sediment waters have been studied.

Glacial-interglacial bioproductivity of the Mexican Margin

Sedimentary accumulation of biogenic components (organic carbon, opal, and biogenic barium) on the northwestern Mexican margin declined during every glacial interval of the past 140 kyr, indicating decreases in upwelling-induced productivity during cold periods. The glacial-interglacial contrasts in upwelling on this margin are attributed to reversals in land-ocean thermal contrast, the waxing and waning of the Laurentide Ice Sheet, and consequent responses of the western hemisphere wind fields. This scenario is consistent with three independent lines of evidence: terrestrial paleoclimatic data, general circulation model results, and our marine records. This pattern of glacial-interglacial variability in upwelling off NW Mexico is opposite to that observed in other low-latitude and midlatitude upwelling areas, such as the eastern equatorial Pacific. These results add to a growing pool of observations that the response of oceanic upwelling to glacial climatic forcing has been regionally variable.

The foundation of the Mexican welfare state and social security reform in the 1990s

Before 1982 Mexico's welfare state regime was a limited conservative one that put priority on the social security of organized labor. But following the country's debt crisis in 1982, this regime changed to a hybrid liberal model. The Ernest Zedillo government (1995-2000) in particular pushed ahead with liberal reform of the social security system. This paper examines the characteristics and the policy making of the social security reforms in the 1990s. The results suggest that underlying these reforms was the restructuring of the economy and the need to cope with the cost of this restructuring. The paper also points out that one of the main factors making possible the rapid execution of the reforms were the weakened political clout of the officialist labor unions due to their steady breakdown during the 1990s and the increase in the monopolistic power of the state vis-a-vis the position of labor during the negotiations on social security reforms.

The Degree of Competition in the Thai Banking Industry before and after the East Asian Crisis

This paper analyzes the influence of the East Asian crisis and the subsequent reforms on the oligopolistic nature of the Thai banking industry. Since the crisis, there have been substantial changes in competitive environment, including a decline in the family ownership of banks as well as the arrival of new entrants. How did these changes affect a banking industry in which the six largest local banks accounted for over 70 percent of market share? The estimated Lerner index from Bresnahan's [1989] conjectural variation model indicates the possibility of a decline in the degree of competition.

Executive Managers in Large Mexican Family Businesses

The involvement of members of owners' families in the running of large family businesses in Mexico is decreasing. Although family members still hold key posts such as that of CEO, other executive posts tend to be delegated to professional salaried managers. Top managers, including family members, share some common characteristics. They are young compared with managers in other developed countries, their quality as human resources is high, and many of them are graduates of overseas MBA courses. Most of them are sufficiently experienced. Improvement of quality among top managers is a recent phenomenon in Mexico, and has been encouraged mainly by the following two factors. First, globalization of business activities was promoted by intense competition among firms under conditions of market liberalization. In order to equip themselves with the ability to cope with the globalization of their operations, large family businesses tried hard to improve the quality of top management, by training and educating existing managers, and/or by recruiting managers in the outside labor market. Second, developments in the Mexican economy during the 1990s led to a growth in the labor market for top managers Thus, business restructuring caused by bankruptcy, as well as mergers and acquisitions, privatization and so on, led to the dismissal of business managers who then entered the labor market in large numbers. The increasing presence of these managers in the labor market helped family businesses to recruit well-qualified senior executives.

Market discipline by depositors : impact of deposit insurance on the Indonesian banking sector

This paper investigates market discipline by depositors in the Indonesian banking sector. Does depositor discipline fulfill its role in Indonesia? Does deposit insurance affect depositor behavior thereby imposing discipline on banks? These questions are empirically examined using panel data on Indonesian commercial banks from 1998 to 2009. In Indonesia deposit insurance was introduced in 2005. Depositor discipline is examined by two measures: change in the amount of deposits and interest rate. The empirical results show that depositors pay attention to bank soundness and riskiness and select banks based on the bank's condition with particular attention paid to equity ratio. It is found that depositors impose discipline on banks, but it varies according to regulatory and economic circumstances.
