Population size or population density? An empirical examination of scale economies in South Australian local government, 2015/16

ABSTRACT

Advocates of amalgamation typically claim that substantial scale economies flow from municipal mergers, which generate larger local government entities by population size. We examined whether economies of scale exist in council outlays by analysing the expenditure of 68 South Australian local government areas using data from the 2015/16 financial year. However, given the correlation between population size and population density it is important to determine whether the influence of population size on expenditure is due to variations in population density. We find that when local government areas are stratified into subgroups on the basis of population density, the evidence of economies of scale largely evaporates. From a policy perspective, this suggests that in place of municipal mergers, policymakers should instead explore avenues for shared service arrangements in those functions which exhibit scale economies.     

Outcome of sex determination from ulnar and radial ridge densities of Brazilians’ fingerprints: Applying an existing method to a new population

Fingerprints do not repeat, varying from region to region on the same fingerprint and from person to person. Using this morphological exclusivity in the individualization of people is considered one of the most reliable methods of identification worldwide. Many populations have been studied with respect to sex determination from fingerprints. In this study, the ridge density from two different areas - ulnar and radial - of the ten fingerprints from 100 Brazilian men and 100 Brazilian women was ascertained and statistically analyzed. The aim was to check whether these characteristics depended on sex to distinguish them categorically. Women had significantly higher ridge density in both areas for the fingers analyzed globally. Sometimes, men and women showed statistically significant differences in hands and fingers. From ulnar and radial ridge densities, this research developed thresholds for sexual discrimination cases of human identification in Brazil.

Gary Becker’s economics of population: reproduction and neoliberal biopolitics

This paper argues that Chicago School economist Gary Becker’s theory of fertility underpins contemporary rationalities of global population governance. Drawing on feminist critiques of biopolitics, the paper proposes reproduction as a missing link that ties Becker’s homo economicus to the aggregate question of population. It argues that Becker’s work challenged macroeconomic theories of fertility by figuring reproduction, and hence population patterns, as governed by the personal utility-maximizing decisions of individuals. It further examines how his approach to fertility inaugurated reproductive decision-making as a regulatory node of population quality, one also tied to a particular sex, race and class politics. Finally, the paper briefly analyses the relationship between Becker’s contribution and today’s focus on women’s reproductive and productive decision-making in population governance in the context of development.     

Forensic and population genetic analysis of Serbian population using 21 STR loci of GlobalFiler™ PCR amplification kit

Autosomal short tandem repeats (STRs) have been widely used in forensic investigations. Prior to the application of any DNA based identification method, it is essential to estimate the allele frequencies and forensic statistical parameters of targeted STR loci in each population in order to provide a more precise reference database for forensic investigation. The GlobalFiler™ Kit is a multiplex assay that combines the 13 original CODIS loci with 7 non-overlapping loci from the expanded European Standard Set (ESS), as well as the highly discriminating SE33 locus, two Y-based loci and the sex determining maker, Amelogenin. The full complement of loci in the GlobalFiler™ Kit are: D13S317, D7S820, D5S818, CSF1PO, D1S1656, D12S391, D2S441, D10S1248, D18S51, FGA, D21S11, D8S1179, vWA, D16S539, TH01, D3S1358, AMEL, D2S1338, D19S433, DYS391, TPOX, D22S1045, SE33 and a Y-specific insertion/deletion locus (Yindel). The 6-dye GlobalFiler™ PCR Amplification kit (ThermoFisher Scientific) comprises 21 autosomal STRs have already been proven to be able to provide reliable DNA profiling results and enhance the power of discrimination between individuals. In this study, we are presenting an analysis of GlobalFiler STR loci on 209 unrelated individuals from Serbia.     

Is China’s rise now stalling?

The variations on power transition theory so widely used to frame analysis of U.S.–China relation tend to assume the inevitability or at least strong probability of China surpassing the United States in economic power if not necessarily military power. In the terminology of social psychology’s attribution theory, China is imputed with the identity of a state that is inevitably rising. The Chinese Communist Party encourages this attribution among Chinese people and foreigners. But China’s economic rise – the foundation of its comprehensive rise – appears to have entered an inflection point in the mid-2010s and may now be stalling. In critical respects, China increasingly resembles the last two countries that ‘attempted’ a globe-level rise: the unsuccessful cases of postwar Japan and the Soviet Union. China’s labor force is shrinking; the country relies excessively on unsustainable debt increases to fuel economic growth; and pollution is seriously harming public health. But even if China’s rise conclusively stalls, it may take quite some time before the Chinese public and outside observers recognize the new reality because of intrinsic biases in the cognitive logic of attributing identities to actors.
