    At a time when cities are competing with one another to attract or retain jobs within a globalizing economy, city governments are providing an array of financial incentives to stimulate job growth and retain existing jobs, particularly in high cost locations. This paper provides the first systematic and comprehensive analysis of datasets on economic development incentives in New York City over the last fifteen years. The evidence on job retention and creation is mixed. Although many companies do not meet their agreed-upon job targets in absolute terms, the evidence suggests that companies receiving subsidies outperform their respective industries in terms of employment growth, that is, the grow more, or decline less. We emphasize that this finding is difficult to interpret, since firms receiving incentives may not be representative of the industry as a whole. In other words, their above-average performance may simply reflect the fact that the Economic Development Corporation (EDC) selects economically promising companies within manufacturing (or other industries) when granting incentives. At the same time, it is also possible that receiving incentives helps these companies to become stronger.economic development incentives; job growth; manufacturing; subsidies; urban development; economic development policy

    The Nature of Race: the Genealogy of the Concept and the Biological Construct’s Contemporaneous Utility

    Racial constructionists, anti-naturalists, and anti-realists have challenged users of the biological race concept to provide and defend, from the perspective of biology, biological philosophy, and ethics, a biologically informed concept of race. In this paper, an ontoepistemology of biology is developed. What it is, by this, to be "biological real" and "biologically meaningful" and to represent a "biological natural division" is explained. Early 18th century race concepts are discussed in detail and are shown to be both sensible and not greatly dissimilar to modern concepts. A general biological race concept (GBRC) is developed. It is explained what the GBRC does and does not entail and how this concept unifies the plethora of specific ones, past and present. Other race concepts as developed in the philosophical literature are discussed in relation to the GBRC. The sense in which races are both real and natural is explained. Racial essentialism of the relational sort is shown to be coherent. Next, the GBRC is discussed in relation to anthropological discourse. Traditional human racial classifications are defended from common criticisms: historical incoherence, arbitrariness, cluster discordance, etc. Whether or not these traditional human races could qualify as taxa subspecies – or even species – is considered. It is argued that they could qualify as taxa subspecies by liberal readings of conventional standards. Further, it is pointed out that some species concepts potentially allow certain human populations to be designated as species. It is explained why, by conventional population genetic and statistical standards, genetic differences between major human racial groups are at least moderate. Behavioral genetic differences associated with human races are discussed in general and in specific. The matter of race differences in cognitive ability is briefly considered. Finally, the race concept is defended from various criticisms. First, logical and empirical critiques are dissected. These include: biological scientific, sociological, ontological, onto-epistemological, semantic, and teleological arguments. None are found to have any merit. Second, moral-based arguments are investigated in context to a general ethical frame and are counter-critiqued. Racial inequality, racial nepotism, and the “Racial Worldview" are discussed. What is dubbed the Anti-Racial Worldview is rejected on both empirical and moral grounds. Finally, an area of future investigation – the politics of the destruction of the race concept – is pointed to

    Keys to Eukaryality: Planctomycetes and Ancestral Evolution of Cellular Complexity

    Get PDF
    Planctomycetes are known to display compartmentalization via internal membranes, thus resembling eukaryotes. Significantly, the planctomycete Gemmata obscuriglobus has not only a nuclear region surrounded by a double-membrane, but is also capable of protein uptake via endocytosis. In order to clearly analyze implications for homology of their characters with eukaryotes, a correct understanding of planctomycete structure is an essential starting point. Here we outline the major features of such structure necessary for assessing the case for or against homology with eukaryote cell complexity. We consider an evolutionary model for cell organization involving reductive evolution of Planctomycetes from a complex proto-eukaryote-like last universal common ancestor, and evaluate alternative models for origins of the unique planctomycete cell plan. Overall, the structural and molecular evidence is not consistent with convergent evolution of eukaryote-like features in a bacterium and favors a homologous relationship of Planctomycetes and eukaryotes

    Gene discovery within the planctomycete division of the domain Bacteria using sequence tags from genomic DNA libraries

    BACKGROUND: The planctomycetes comprise a distinct group of the domain Bacteria, forming a separate division by phylogenetic analysis. The organization of their cells into membrane-defined compartments including membrane-bounded nucleoids, their budding reproduction and complete absence of peptidoglycan distinguish them from most other Bacteria. A random sequencing approach was applied to the genomes of two planctomycete species, Gemmata obscuriglobus and Pirellula marina, to discover genes relevant to their cell biology and physiology. RESULTS: Genes with a wide variety of functions were identified in G. obscuriglobus and Pi. marina, including those of metabolism and biosynthesis, transport, regulation, translation and DNA replication, consistent with established phenotypic characters for these species. The genes sequenced were predominantly homologous to those in members of other divisions of the Bacteria, but there were also matches with nuclear genomic genes of the domain Eukarya, genes that may have appeared in the planctomycetes via horizontal gene transfer events. Significant among these matches are those with two genes atypical for Bacteria and with significant cell-biology implications - integrin alpha-V and inter-alpha-trypsin inhibitor protein - with homologs in G. obscuriglobus and Pi. marina respectively. CONCLUSIONS: The random-sequence-tag approach applied here to G. obscuriglobus and Pi. marina is the first report of gene recovery and analysis from members of the planctomycetes using genome-based methods. Gene homologs identified were predominantly similar to genes of Bacteria, but some significant best matches to genes from Eukarya suggest that lateral gene transfer events between domains may have involved this division at some time during its evolution

    The Planctomycetes: Emerging Models for Microbial Ecology; Evolution and Cell Biology

    Get PDF
    The planctomycetes are budding bacteria forming one of the phylogenetically distinct major phyla of the domain Bacteria defined by 16S rRNA sequence analysis. They are distinctive phenotypically in their budding reproduction and the complete absence of peptidoglycan in their proteinaceous cell walls. Planctomycetes are proving to be of increasing relevance to microbial ecology, due to their ubiquitous distribution in aquatic including marine habitats, to molecular evolution due to their separate and potentially deep-branching position within the Bacteria and potential relations to chlamydiae, and to cell biology, due to their unusual cell wall composition for Bacteria, gene organization, and the occurrence in Gemmata obscuriglobus of a membrane-bounded nucleoid with implications for understanding the eukaryote nucleus and its evolution. All these aspects of the emerging significance of the planctomycetes are reviewed here

    County-level USA: No Robust Relationship between Geoclimatic Variables and Cognitive Ability

    Get PDF
    Using a sample of ~3,100 U.S. counties, we tested geoclimatic explanations for why cognitive ability varies across geography. These models posit that geoclimatic factors will strongly predict cognitive ability across geography,even when a variety of common controls appear in the regression equations.Our results generally do not support UV radiation (UVR) based or other geoclimatic models. Specifically, although UVR alone predicted cognitive ability at the U.S. county-level (β = -.33), its validity was markedly reduced in the presence of climatic and demographic covariates (β = -.16), and was reduced even further with a spatial lag (β = -.10). For climate models,average temperature remained a significant predictor in the regression equation containing a spatial lag (β = .35). However, the effect was in the wrong direction relative to typical cold weather hypotheses. Moreover,when we ran the analyses separately by race/ethnicity, no consistent pattern appeared in the models containing the spatial lag. Analyses of gap sizes across counties were also generally inconsistent with predictions from the UVR model. Instead, results seemed to provide support for compositional models

    Molecular and Ultrastructural Confirmation of Classification of ATCC 35122 as a Strain of Pirellula staleyi

    A freshwater isolate from Campus Lake, Baton Rouge, LA, USA, strain ATCC 35122 (= ICPB 4362 = Schmidt CLPM White = Tekniepe BT2 white), which had been proposed as a putative reference strain for 'Planctomyces staleyi' (later reclassified as Pirellula staleyi), has been re-examined to establish its relationship to the type strain of Pirellula staleyi, ATCC 27377T. 16S rRNA sequencing confirms its very close relationship to ATCC 27377T and its membership of the order Planctomycetales. Ultrastructural characteristics are also consistent with its membership of the planctomycetes and of the genus Pirellula. These characteristics include polar crateriform structures and the occurrence of the unique internal, single- membrane-bounded compartment enclosing the nucleoid and ribosome-like particles, the pirellulosome, and a polar cap region. Cells of strain ATCC 35122 often displayed pointed, hump-like protrusions opposite each other on the cell, constituting prosthecae, and these were also found to be present on cells of strain ATCC 27377T. The original identification of ATCC 35122 as a strain of Pirellula staleyi is confirmed on both molecular and phenotypic grounds
