The allometry of primate reproductive parameters

This study is based on the comparison of quantative information on the reproduction and development of individual species classified within a single mammalian order, the Primates. The main method of comparison uses logarithmic transformation of values, derived from the literature, zoological garden records and the author's observations, following the established analytical approach known as interspecific allometry. The interrelation of rates, ages and sizes of the average species members at different periods in the life cycle are examined principally in terms of energy flow. Since there is some confusion in the literature concerning the value of such analysis, attention is also given to questions of theory and method. / The three results sections deal in turn with: 1) the foetal growth period; discussion includes associated relations in placental morphology, the growth of brain and body and the energetic stress on the mother 2) the postnatal growth period; discussion involves the associations of seasonality with the relatively rapid postnatal growth of strepsirhine infants, and of maternal milk production to haplorhine infant growth 3) the reproductive potential of the species; discussion includes the relation of body size and ecology with the potential for population growth. The primates are established as the most efficient users of energy for the maintenance of living tissue for their size. / The discussion of both theory and the found results elaborates on thermodynamic concepts of life. Not only do primates have great complexity in their physiology and ecological relations but this complexity is expressed in the ability of these living forms to preserve both physiology and population structure from the random disruptive effects of the environment. A short section is included on the evolution of Homo sapiens

Ongoing declines of woodland birds: are restoration plantings making a difference?

Woodland birds are a species assemblage of conservation concern, and their persistence in fragmented agricultural landscapes is dependent on both the preservation of existing woodland remnants and the implementation of restoration plantings. However, little is known about the habitat-use and persistence of birds in fragmented agricultural landscapes. We present a detailed, population-oriented study of woodland birds in temperate eucalypt woodland restoration plantings and remnant woodland patches in the South-west Slopes bioregion of New South Wales, Australia. First, we undertook a 3-yr mark–recapture project to assess annual survival and site fidelity in restoration plantings and woodland remnants. We supplemented our recapture efforts with resightings of color-banded individuals. Second, we tracked individual birds of two species, Superb Fairywren (Malurus cyaneus) and Willie Wagtail (Rhipidura leucophrys), and documented snapshots of their home ranges and movement patterns during the breeding season. Annual survival in the woodland bird assemblage was lower than expected (51%). Home ranges of the Superb Fairywren were positively correlated with patch size, and were constrained by patch edges in linear sites. Superb Fairywrens and Willie Wagtails were more likely to travel longer distances between substrates while foraging in linear sites. Willie Wagtails engaged in significant gap-crossing (up to 400 m) between adjacent habitat patches. Our findings indicate that (1) patch isolation and certain patch configurations place resident birds at an energetic disadvantage, and (2) in our study area, woodland bird populations are continuing to decline. We recommend landscape-scale habitat restoration programs aim to address ongoing population declines. Studies such as ours conducted over longer time periods would provide a deeper understanding of habitat use and population processes of woodland birds in fragmented agricultural landscapes.Australian Academy of Science Riverina Local Land Services National Environmental Science Program Lesslie Endowment Australian Bird Study Associatio

Data cultures of mobile dating and hook-up apps : emerging issues for critical social science research

The ethical and social implications of data mining, algorithmic curation and automation in the context of social media have been of heightened concern for a range of researchers with interests in digital media in recent years, with particular concerns about privacy arising in the context of mobile and locative media. Despite their wide adoption and economic importance, mobile dating apps have received little scholarly attention from this perspective – but they are intense sites of data generation, algorithmic processing, and cross-platform data-sharing; bound up with competing cultures of pro- duction, exploitation and use. In this paper, we describe the ways various forms of data are incorporated into, and emerge from, hook-up apps’ business logics, socio-technical arrangements, and cultures of use to produce multiple and intersecting data cultures. We propose a multi-layered research agenda for critical and empirical inquiry into this field, and suggest appropriate conceptual and methodological frameworks for exploring the social and political challenges of data cultures

Calibration of Photomultiplier Tubes for the Fluorescence Detector of Telescope Array Experiment using a Rayleigh Scattered Laser Beam

We performed photometric calibration of the PhotoMultiplier Tube (PMT) and readout electronics used for the new fluorescence detectors of the Telescope Array (TA) experiment using Rayleigh scattered photons from a pulsed nitrogen laser beam. The experimental setup, measurement procedure, and results of calibration are described. The total systematic uncertainty of the calibration is estimated to be 7.2%. An additional uncertainty of 3.7% is introduced by the transport of the calibrated PMTs from the laboratory to the TA experimental site.Comment: 43 pages, 15 figure

‘No expectations’: straight men's sexual and moral identity-making in non-monogamous dating

This article juxtaposes the discursive strategies of two groups of heterosexual men in the context of non-monogamous internet-mediated dating in Belgium, notably men who are open about their extra-dyadic sexual practices and 'cheating' men. The analysis shows that regardless of the men's use of openness or discretion to construct narratives of sexual identity, morality and care, their accounts seem to be deeply intertwined with monogamist and gendered ideas on sex, care and commitment, which serves to define a largely uncaring and consumeristic dating culture. The article argues that attentiveness to power inequalities should be the main focus of 'ethical' non-monogamy

Outside the gate: sub-urban legal practices in early medieval England

Many aspects of English early medieval (Anglo-Saxon) legal landscapes can be discerned in archaeological and toponymic evidence, ranging from the locations of legislative councils and judicial assemblies to sites of capital punishment. Among the corpus of such sites a striking group can be detected at the periphery of urban spaces. Gates into a number of towns appear to have functioned as legislative meeting-places, and even gave their names to some legally constituted communities, while suburban locations also feature prominently as sites of gallows and public punishment. In this paper historical, archaeological and toponymic evidence is used to examine this phenomenon of suburban legal practices and to pose questions about the wider dimensions of the early medieval legal landscape

To sort, to match and to share: addressivity in online dating platforms

This paper analyses addressivity in online dating platforms, with OkCupid as its focus. Drawing from Mikhail Bakhtin’s theory of addressivity, I argue the need for a generic account of online dating – one that focuses on the particular kinds of address that typify expressive scenarios on its platforms. Rather than focusing solely on how users address themselves to other users, I instead examine several layers of addressivity within the online dating scenario: (1) users addressing other users, (2) users addressing platforms, (3) platforms addressing publics, and (4) companies addressing investors, and (5) investors addressing users. I argue that within surveillance capitalism generally, and within online dating platforms in particular, there is an imbalance of addressivity: though online users are broadly aware that their data may be collected and analysed, they are nonetheless unconscious of and/or uncomfortable with this form of sharing, because it does not easily fit into previously known narratives of dating. In other words, the automatic gathering and analysis of data by OkCupid is a background condition of all its users’ activity – but this is not sufficiently accounted for in users’ generic understandings of online dating. OkCupid cofounder Christian Rudder’s continual efforts to make online dating data analytics both understandable and palatable for users (via OkCupid’s promotional material, TED-Ed talks, a blog, and a book on data) aims, in part, to address this imbalance. These stagings of the platform’s address to its users aim to garner interest in, and acceptance of, becoming part of aggregated, privatized data sets – and indeed, coming to be witnessed and assetized by the automated gaze of data analytics. Many accounts of online surveillance reiterate paranoid modes of enquiry (‘they are watching us’). Alternatively, this article investigates how surveillance capitalism produces libidinal investments in automated match-making, naturalizing platforms’ layered modes of address

The evolving SARS-CoV-2 epidemic in Africa: insights from rapidly expanding genomic surveillance

Investment in SARS-CoV-2 sequencing in Africa over the past year has led to a major increase in the number of sequences generated, now exceeding 100,000 genomes, used to track the pandemic on the continent. Our results show an increase in the number of African countries able to sequence domestically, and highlight that local sequencing enables faster turnaround time and more regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and shed light on the distinct dispersal dynamics of Variants of Concern, particularly Alpha, Beta, Delta, and Omicron, on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve, while the continent faces many emerging and re-emerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
