    Description: Only ten years ago, there were more internet users in countries like France or Germany than in all of Africa put together. But much has changed in a decade. The year 2018 marks the first year in human history in which a majority of the world’s population are now connected to the internet. This mass connectivity means that we have an internet that no longer connects only the world’s wealthy. Workers from Lagos to Johannesburg to Nairobi and everywhere in between can now apply for and carry out jobs coming from clients who themselves can be located anywhere in the world. Digital outsourcing firms can now also set up operations in the most unlikely of places in order to tap into hitherto disconnected labour forces. With CEOs in the Global North proclaiming that ‘location is a thing of the past’ (Upwork, 2018), and governments and civil society in Africa promising to create millions of jobs on the continent, the book asks what this ‘new world of digital work’ means to the lives of African workers. It draws from a year-long fieldwork in South Africa, Kenya, Nigeria, Ghana, and Uganda, with over 200 interviews with participants including gig workers, call and contact centre workers, self-employed freelancers, small-business owners, government officials, labour union officials, and industry experts. Focusing on both platform-based remote work and call and contact centre work, the book examines the job quality implications of digital work for the lives and livelihoods of African workers.

    Description: The hope and hype about African digital entrepreneurship, contrasted with the reality on the ground in local ecosystems. In recent years, Africa has seen a digital entrepreneurship boom, with hundreds of millions of dollars poured into tech cities, entrepreneurship trainings, coworking spaces, innovation prizes, and investment funds. Politicians and technologists have offered Silicon Valley–influenced narratives of boundless opportunity and exponential growth, in which internet-enabled entrepreneurship allows Africa to “leapfrog” developmental stages to take a leading role in the digital revolution. This book contrasts these aspirations with empirical research about what is actually happening on the ground. The authors find that although the digital revolution has empowered local entrepreneurs, it does not untether local economies from the continent's structural legacies. Drawing on a five-year research project, the authors show how entrepreneurs creatively and productively adapt digital technologies to local markets rather than dreaming of global dominance, achieving sustainable businesses by scaling based on relationships and customizing digital platform business models for African infrastructure challenges. The authors examine African entrepreneurial ecosystems; show that African digital entrepreneurs have begun to form a new professional class, becoming part of a relatively exclusive cultural and economic elite; and discuss the impact of Silicon Valley's mythologies and expectations. Finally, they consider the implications of their findings and offer recommendations to policymakers and others.

    Description: Prior to the third century A.D., two broad Roman conceptions of frontiers proliferated and competed: an imperial ideology of rule without limit coexisted with very real and pragmatic attempts to define and defend imperial frontiers. But from about A.D. 250-500, there was a basic shift in mentality, as news from and about frontiers began to portray a more defined Roman world—a world with limits—allowing a new understanding of frontiers as territorial and not just as divisions of people. This concept, previously unknown in the ancient world, brought with it a new consciousness, which soon spread to cosmology, geography, myth, sacred texts, and prophecy. The "frontier consciousness" produced a unified sense of Roman identity that transcended local identities and social boundaries throughout the later Empire. Approaching Roman frontiers with the aid of media studies as well as anthropological and sociological methodologies, Mark W. Graham chronicles and documents this significant transition in ancient thought, which coincided with, but was not necessarily dependent on, the Christianization of the Roman world.

    Description: Anthropological Explorations in Queer Theory offers a wide ranging fusion of queer theory with anthropological theory, shifting away from the discussion of gender categories and identities that have often constituted a central concern of queer theory and instead exploring the queer elements of contexts in which they are not normally apparent. Engaging with a number of apparently 'non-sexual' topics, including embodiment and fieldwork, regimes of value, gifts and commodities, diversity discourses, biological essentialisms, intersectionality, the philosophy of Bergson and Deleuze, and the representation of heterosexuality in popular culture, this book moves to discuss central concerns of contemporary anthropology, drawing on both the latest anthropological research as well as classic theories. In broadening the field of queer anthropology and opening queer theory to a number of new themes, both empirical and theoretical, Anthropological Explorations in Queer Theory will appeal not only to anthropologists and queer theorists, but also to geographers and sociologists concerned with questions of ontology, materiality and gender and sexuality.

    Notes: An experimental study on turbulent pipe flows was conducted with a view to reduce their friction drag by oscillating a section of the pipe in a circumferential direction. The results indicated that the friction factor of the pipe is reduced by as much as 25% as a result of active manipulation of near-wall turbulence structure by circular-wall oscillation. An increase in the bulk velocity was clearly shown when the pipe was oscillated at a constant head, supporting the measured drag reduction in the present experiment. The percentage reduction in pipe friction was found to be better scaled with the nondimensional velocity of the oscillating wall than with its nondimensional period, confirming a suggestion that the drag reduction seem to be resulted from the realignment of longitudinal vortices into a circumferential direction by the wall oscillation. © 1998 American Institute of Physics.

    Notes: Refers to past research regarding gender differences in investment strategies which has pointed to two important differences: female investors appear both to be more risk averse and to have less confidence in their investment decisions than male investors in equivalent circumstances. Given the relative consistency of these findings, as well as the potential long-term financial implications of these differing investment strategies, surprisingly little research has focused on the underlying reasons for these gender differences. Proposes that gender differences in information processing styles may account for the lower risk-taking tendencies among female investors as well as the tendency toward lower confidence levels. Implications regarding marketing strategies for the financial services sector are discussed.

    Notes: Abstract. The identification of genomic rearrangements involving more than 0.5 kb of the BRCA1 gene has confirmed a more complex mutation spectrum than was initially appreciated. Genomic rearrangements in BRCA1 represent 15% of all mutations in a group of French and American breast and ovarian cancer families and 36% of all mutations in a group of Dutch families. The rearrangements described to date range in size from 510 bp to 23.8 kb, are found throughout the gene, and are most frequently attributable to homologous recombination. We describe the identification of rearrangements in two breast and ovarian cancer families that involve 3.4 and 11.5 kb of the BRCA1 gene and span multiple exons but maintain the reading frame. Both gene rearrangements appear to result from Alu-mediated homologous recombination and have been detected by using a combination of protein truncation analysis and Southern blot analysis. These rearrangements result in the loss of amino acids that lie at the carboxy-terminus of the protein and that have previously been shown to have functional significance. Because these rearrangements result in the deletion of exons but maintain the reading frame, they may provide insights into specific regions and amino acids that have functional significance for the BRCA1 protein.

    Notes: Abstract Oxygen consumption (VO2) of juvenile Arctic cod (Boreogadus saida) was investigated at low tempera tures (six temperatures; range -0.5 to 2.7°C). Small (mean wt. 6–8 g) and large (mean wt. 14 g) fish were acclimated, or adjusted to a constant temperature (0.4°C), for 5 months and then tested for metabolic cold adaptation (elevated metabolic rates in polar fishes). Short-term (2 weeks) acclimated fish showed elevated VO2 similar to previously established values for polar fishes, but there was no such evidence after longterm acclimation. Long-term acclimation caused VO2 values to drop significantly (from 86.0 to 46.5 mg O2·kg−1·h−1, at 0.4°C), which showed that metabolic cold adaptation was a phenomenon caused by insufficien: acclimation time for fish in respiration experiments. We also measured the effects of temperature and feeding on VO2. A temperature increase of 2.3°C resulted in relatively large increases in VO2 for both longand short-term acclimated fish (Q10 = 6.7 and 7.1, respectively), which suggests that metabolic processes are strongly influenced by temperature when it is close to zero. Feeding individuals to satiation caused significant increases in VO2 above pre-fed values (34–60% within 1–2 days after feeding). Respiration budgets of starved and fed Arctic cod at ambient temperatures in Resolute Bay N.W.T., Canada, were used to model annual respiration costs and potential weight loss. Low respiration costs for Arctic cod at ambient temperatures result in high growth efficiency during periods of feeding and low weight loss during periods of starvation.
