The Role of Human Capital in Earnings Differences between Black and White Men

D uring the past 50 years, the earnings of black men have increased substantially both in absolute terms and relative to those of white men, as shown in Figure 1. In 1940 the black-white weekly earnings ratio among men ages 25-34 was 49 percent; by 1980 it had increased to 79 percent. During the 1980s, however, the overall black-white earnings gap did not narrow, and at younger ages the gap actually widened. Although the 1980s is not the first decade since 1940 in which black men made little or no gains in relative earnings-the 1950s was another-the lack of progress in the 1980s is nevertheless puzzling and a source of concern. This article examines the factors underlying the differential in earnings between black men and white men, with a focus on the role of human capital. Since 1940, successive generations of black men entering the labor force have been increasingly more educated relative to white men, both in terms of years of school completed and in the quality of schooling obtained. As the education and income levels of black parents increased, racial differences in the transmission of human capital in the home were also likely to have narrowed. This convergence in educational differences combined with the migration of blacks out of the South contributed to the narrowing in the racial gap in earnings over the 1940-80 period, particularly in the first half of the period. But human capital factors-education and migration-were not the only source of convergence in black-white differences in earnings. The patterns of change in the earnings gap support the contention that declining labor market discrimination against blacks has also contributed to the rise in the black-white earnings ratio. Moreover, the acquisition of human capital itself has been strongly affected by societal and governmental discrimination, since blacks were long provided with greatly inferior schooling resources.
Economic development and the geography of institutions

To explain cross-country income differences, research has recently focused on the so-called deep determinants of economic development, notably institutions and geography. This article shows that it is not only absolute geography, in terms of for instance climate or being landlocked, but also relative geography, the spatial linkages between countries, that matters for a country's GDP per capita. More specifically, we analyze the importance of the geography of institutions. We show that apart from its own institutions, the institutional quality in neighboring countries is also important for a country's economic development. This finding is robust to various alternative specifications of relative geography, sample size and the inclusion of additional controls.
International Corporate Governance and Corporate Cash Holdings

Abstract Agency problems are an important determinant of corporate cash holdings. For a sample of more than 11,000 firms from 45 countries, we find that corporations in countries where shareholders rights are not well protected hold up to twice as much cash as corporations in countries with good shareholder protection. In addition, when shareholder protection is poor, factors that generally drive the need for cash holdings, such as investment opportunities and asymmetric information, actually become less important. These results are stronger after controlling for capital market development. Indeed, consistent with the importance of agency costs, we find that firms hold larger cash balances when access to funds is easier. Our evidence is consistent with the conjecture that investors in countries with poor shareholder protection cannot force managers to disgorge excessive cash balances.
Mobilization of intensive care patients: a multidisciplinary practical guide for clinicians

Objectives To describe our experience and the practical tools we have developed to facilitate early mobilization in the intensive care unit (ICU) as a multidisciplinary team. Background Despite the evidence supporting early mobilization for improving outcomes for ICU patients, recent international point-prevalence studies reveal that few patients are mobilized in the ICU. Existing guidelines rarely address the practical issues faced by multidisciplinary ICU teams attempting to translate evidence into practice. We present a comprehensive strategy for safe mobilization utilized in our ICU, incorporating the combined skills of medical, nursing, and physiotherapy staff to achieve safe outcomes and establish a culture which prioritizes this intervention. Methods A raft of tools and strategies are described to facilitate mobilization in ICU by the multidisciplinary team. Patients without safe unsupported sitting balance and without ≥3/5 (Oxford scale) strength in the lower limbs commence phase 1 mobilization, including training of sitting balance and use of the tilt table. Phase 2 mobilization involves supported or active weight-bearing, incorporating gait harnesses if necessary. The Plan B mnemonic guides safe multidisciplinary mobilization of invasively ventilated patients and emphasizes the importance of a clearly articulated plan in delivering this valuable treatment as a team. Discussion These tools have been used over the past 5 years in a tertiary ICU with a very low incidence of adverse outcomes (<2%). The tools and strategies described are useful not only to guide practical implementation of early mobilization, but also in the creation of a unit culture where ICU staff prioritize early mobilization and collaborate daily to provide the best possible care. Conclusion These practical tools allow ICU clinicians to safely and effectively implement early mobilization in critically ill patients. A genuinely multidisciplinary approach to safe mobilization in ICU is key to its success in the long term.
A System of Othermothering: Student Affairs Administrators' Perceptions of Relationships with Students at Historically Black Colleges

This study analyzed data gathered from interviews with professionals at historically Black colleges and universities (HBCUs) to examine the nature of relationships student affairs administrators form with students. The data were interpreted through the guardianship conceptual framework found in African American feminist literature. Results reveal how the notion of “othermothering” permeates relationships at HBCUs and the considerable importance attached to those formed between students and student affairs administrators. Relationships serve as a primary means to facilitate student retention at HBCUs and ensure the continued existence of a unique type of institution.
Prenatal tobacco and marijuana use among adolescents: effects on offspring gestational age, growth, and morphology.

OBJECTIVE This longitudinal study examined the effects of tobacco and marijuana use during pregnancy on the gestational age, growth, and morphology of 310 offspring of adolescents. Data were collected during 1990 through 1993. METHODOLOGY The adolescents were drawn from a prenatal clinic in Pittsburgh, PA. They were interviewed at mid-pregnancy and at delivery to obtain information on tobacco, marijuana, and other substance use before and during pregnancy. Infants were examined 24 to 36 hours after birth. RESULTS The average maternal age was 16.1 (range 12 to 18 years); 70% were African-American. Prenatal tobacco use was associated with reduced birth weight, length, head and chest circumferences, and ponderal index, but not gestational age or the number of morphological abnormalities. Prenatal marijuana exposure was associated with reduced gestational age. Among whites, first trimester marijuana exposure was associated with an increased rate of minor physical anomalies. Prenatal marijuana exposure was not associated with any growth outcomes. CONCLUSIONS These effects of prenatal tobacco and marijuana use were prominent despite lower levels of prenatal exposure in the offspring of adolescent mothers as compared with the offspring of adult mothers from the same clinic. Young maternal age may increase the offspring's risk of negative effects from prenatal tobacco and marijuana exposure.
Differentiation of Benign and Malignant Solid Pseudopapillary Neoplasms of the Pancreas

Objective: The aim of this study was to investigate differential imaging features between benign and malignant solid pseudopapillary neoplasms (SPN) of the pancreas on computed tomographic and magnetic resonance imagings. Methods: Between January 2001 and January 2007, we identified 30 patients with confirmed SPN by surgery. The computed tomographic and magnetic resonance images were reviewed by 3 radiologists in consensus. Each tumor was analyzed for the following categories: location of tumor, tumor margin, proportion of solid component, morphology of capsule, growth pattern, calcification, and presence of upstream pancreatic ductal dilatation. Results: Benign SPN usually had oval/round or smoothly lobulated margins, and malignant SPN more commonly had focal lobulated margins (P = 0.027). Presence of complete encapsulation was more frequently seen in benign SPN, whereas focal discontinuity of capsule was more commonly seen in malignant SPN (P = 0.005). There was no statistical difference between benign and malignant tumors in other imaging findings. Conclusions: A focal lobulated margin and a focal discontinuity of the capsule may suggest malignant SPN, whereas a round or smoothly lobulated margin and a complete encapsulation were more commonly seen in benign SPN.
The entorhinal cortex of the monkey: II. Cortical afferents

The entorhinal cortex of the monkey is commonly viewed as the major link between the cerebral cortex and the other fields of the hippocampal formation. Until recently, however, little was known about the origins of the cortical projections to the entorhinal cortex, and most of the available information is still based on degeneration studios. We have carried out a systematic analysis of these connections by placing small injections of the retrograde tracer wheat germ agglutinin conjugated to horseradish peroxidase into each of the fields of the entorhinal cortex of the Macaca fascicularis monkey, Retrograde labeled cells were observed in several areas of the frontal and temporal lobes, the insula, and the cingulate cortex. In the frontal lobe, the greatest number of labeled cells were observed in the orbital region and specifically in areas 13 and 13a: labeled cells were also seen in areas 14, 11, and 12. In the dorsolateral frontal cortex, labeled cells were observed mainly in the rostral half of area 46; occasionally cells were also seen in areas 9, 8, and 6. In the cingulate cortex, labeled cells were observed in area 25, area 32, and rostral levels of area 24; fewer cells were observed at caudal levels of area 24 or in area 23. The retrosplenial region (areas 30 and 29), including its caudal extension along the rostral calcarine sulcus and its ventral extension into the temporal lobe, contained numerous labeled cells. In the temporal lobe, retrogradely labeled cells were arranged in two rostrocaudally oriented bands. Rostral to the hippocampal formation, the first band encompassed the priform and periamygdaloid cortices and areas 35 and 36; the labeling in area 36 was continuous to the temporal pole. At more caudal levels this band was located immediately lateral to the hippocampal formation and included areas 35 and 36 rostrally and areas TH and TF caudally. The second band was situated in the superior temporal gyrus where labeled cells were observed in several distinct cytoarchitectonic fields, including the parainsular cortex in the fundus of the inferior limiting sulcus. In the insula proper, retrogradely labeled cells were seen mainly in the rostral or agranular division; far fewer were observed in the dysgranular and granular insula. Whereas there is little available physiological information concerning many of the cortical regions that project to the entorhinal cortex, on anatomical grounds they may be generally characterized as poly sensory associational regions.
A novel general approach to eucaryotic mutagenesis functionally identifies conserved regions within the adenovirus 13S E1A polypeptide

A new approach to the isolation of mutations in mammalian genes was developed which permits both the selection of infrequently occurring mutants that alter the cellular morphology of recipient cells and the rapid reisolation of the mutant gene. The adenovirus type 5 13S early region 1a (E1a) gene was mutagenized in vitro with sodium bisulfite and then efficiently transferred into cells with a retrovirus shuttle vector. Three classes of mutants of the 13S E1a gene product were isolated, each of which induced a distinct morphological alteration. The mutant E1a gene was reisolated from each cell line, and the precise nucleotide changes were determined. The E1a-induced morphological alterations were further examined by the construction of single and double point mutations within different regions of the polypeptides by utilizing the amino acid substitutions obtained from the original mutants. The results suggest that each of the three regions of highly conserved amino acids within the E1a 13S polypeptide has a distinct role in the alteration of cellular morphology and the activation of gene expression.
The legacy of social conflicts over property rights in rural Brazil and Mexico: Current land struggles in historical perspective

This article proposes an approach to the agrarian question that focuses on the establishment of absolute private property rights over land in Brazil and Mexico. The author argues that current land struggles are conditioned by the property regimes inherited from past struggles. The author examines the liberal reforms of the nineteenth century and argues that the balance of class forces led to the slow establishment of absolute private property in Brazil, while in Mexico they triggered the Revolution of 1910–1917, which limited agrarian capitalism. The author then turns to the consequences of these different property regimes in the twentieth century and argues that capitalist social relations have been more dominant in the Brazilian than in the Mexican countryside. The conservative modernization of the 1960s and 1970s is identified as a turning point in the fully capitalist development of agriculture in Brazil. The shift toward food imports, the elimination of subsidies, and the reform of Article 27 of the Constitution signal the re-establishment of the conditions for capitalist development of agriculture in Mexico. The article ends with an assessment of the MST and EZLN's strategies to protect peasants’ access to land and to influence the institutional setting determining access to land.
Rheumatoid arthritis clinical features and management strategies at an urban tertiary facility in Pakistan.

OBJECTIVE To determine the presentation patterns, biologically vulnerable patient groups and treatment strategies of rheumatoid arthritis. METHODS The retrospective study was conducted at the Rheumatology Clinic of Liaquat National Hospital and Medical College, Karachi, and comprised data of rheumatology patients who presented between September 2006 and September 2012. After screening all the files, rheumatoid arthritis cases were identified. Data collection was done using a questionnaire that included patient demographics, co-morbidities, clinical manifestations and drug therapy. SPSS 13 was used for statistical analysis. RESULTS Of the 2300 files screened, 500(21.7%) related to patients of rheumatoid arthritis. The mean age at presentation of these 500 patients was 41±15 years. There were 367(73.4%) women and they presented at an earlier age compared to men (p<0.024). Erosions were present in 198(40%) patients on X-rays and 22(4.4%) had joint deformities. Seropositive rheumatoid arthritis was associated with higher erythrocyte sedimentation rate levels (p<0.014), but did not differ from seronegative rheumatoid arthritis in terms of Disease Activity Score-28 levels (p<0.21). CONCLUSIONS The skewed gender distribution was likely an effect of rheumatoid arthritis biology rather than due to issues of healthcare accessibility. Seronegative RA is likely to present late though it is as destructive as the seropositive disease.
Biomonitoring of Human Fetal Exposure to Environmental Chemicals in Early Pregnancy

The first trimester of human fetal life, a period of extremely rapid development of physiological systems, represents the most rapid growth phase in human life. Interference in the establishment of organ systems may result in abnormal development that may be manifest immediately or programmed for later abnormal function. Exposure to environmental chemicals may be affecting development at these early stages, and yet there is limited knowledge of the quantities and identities of the chemicals to which the fetus is exposed during early pregnancy. Clearly, opportunities for assessing fetal chemical exposure directly are extremely limited. Hence, this review describes indirect means of assessing fetal exposure in early pregnancy to chemicals that are considered disrupters of development. Consideration is given to such matrices as maternal hair, fingernails, urine, saliva, sweat, breast milk, amniotic fluid and blood, and fetal matrices such as cord blood, cord tissue, meconium, placenta, and fetal liver. More than 150 articles that presented data from chemical analysis of human maternal and fetal tissues and fluids were reviewed. Priority was given to articles where chemical analysis was conducted in more than one matrix. Where correlations between maternal and fetal matrices were determined, these articles were included and are highlighted, as these may provide the basis for future investigations of early fetal exposure. The determination of fetal chemical exposure, at the time of rapid human growth and development, will greatly assist regulatory agencies in risk assessments and establishment of advisories for risk management concerning environmental chemicals.
Mutation of the hamster cell cycle gene RCC1 is complemented by the homologous genes of Drosophila and S.cerevisiae.

The RCC1 gene has been isolated from several vertebrates, including human, hamster and Xenopus. Genes similar to RCC1, namely BJ1 and SRM1/PRP20, have been isolated from the insect Drosophila and from the budding yeast Saccharomyces cerevisiae. A mutation of the RCC1 gene in the hamster BHK21 cell line, tsBN2, confers pleiotropic phenotypes, including G1 arrest and premature induction of mitosis in cells synchronized at the G1/S boundary. Similarly, mutations of the SRM1/PRP20 gene are pleiotropic; the srm1 mutant shows G1 arrest and suppression of the mating defect of mutants lacking pheromone receptors, and the prp20 mutant shows an alteration in mRNA metabolism. Here we show that both BJ1 and SRM1/PRP20 complement the temperature sensitive phenotype of the tsBN2 cells. Like RCC1 proteins of vertebrates, the protein products of the Drosophila and yeast RCC1 homologues were located in the nuclei of the mammalian cells. These results suggest that the BJ1 and SRM1/PRP20 genes are functionally equivalent to the vertebrate RCC1 genes, and that the RCC1 gene plays an important role in the regulation of gene expression in the eukaryotic cell cycle.
Policy Influences on Economic Growth in OECD Countries: An Evaluation of the Evidence

This paper examines the recent literature on economic growth with a focus on policy issues and evidence relevant to OECD countries. The review begins with an overview of developments in the theory of economic growth and also comments generally on the nature of evidence exploring the influences on growth. This is followed by an examination of issues relating to the link between growth and factors of production (physical and human capital). The third section of the paper assesses the evidence linking a number of other factors (or ‘framework conditions’) to growth, namely: macroeconomic policy; finance; trade and competition policy; ‘social capital’; and, population and health issues . Ce document examine la litterature recente sur la croissance economique en particulier sur les aspects empiriques et de politiques economique concernant les pays de l'OCDE. L’etude commence par une vue d'ensemble des developpements de la theorie de la croissance economique et presente egalement des observations generales sur la nature des recherches sur les determinants de la croissance. Suit un examen des implications relatives aux liens entre la croissance et les facteurs de production (capital humain et physique). La troisieme section du document evalue les implications des liens entre un certain nombre d'autres facteurs ('conditions cadres’) a la croissance, a savoir : la politique macro-economique ; la finance ; la politique du commerce et de la concurrence ; le 'capital societal' ; et les aspects lies a la population et la sante .
Internet Appendix to 'Mandatory Financial Reporting and Voluntary Disclosure: The Effect of Mandatory IFRS Adoption on Management Forecasts'

ABSTRACT: This study examines the effect of the mandatory adoption of International Financial Reporting Standards (IFRS) on voluntary disclosure. Using a difference-in-differences analysis, we document a significant increase in the likelihood and frequency of management earnings forecasts following mandatory IFRS adoption, consistent with the notion that IFRS adoption alters firms' disclosure incentives in response to increased capital-market demand. We find the increase to be larger among firms domiciled in code-law countries, suggesting a catching-up effect among firms facing low disclosure incentives pre-adoption. We then propose and test three channels through which IFRS adoption could alter firms' disclosure incentives: improved earnings quality, increased shareholder demand, and increased analyst demand. We find evidence consistent with all three channels.
The Role of Underwriter-Investor Relationships in the IPO Process

Abstract We find that in allocating initial public offerings (IPOs), underwriters favor institutions they have previously worked with. Regular investors benefit more than casual investors in IPOs through greater participation in underpriced issues. Relationship participation is more important in the distribution of IPOs with stronger demand, IPOs of less liquid firms, and deals by less reputable underwriters. Overall, our results are consistent with book-building theories of IPOs. Interestingly, for 1999–2000 we find that regular investors receive even more underpriced IPOs relative to previous years while we do not find evidence that they provide additional services in IPOs.
