African Military History and Historiography
Authors: Parsons Timothy
Published: November 2018

African military history is more than just the study of “tribal warfare,” imperial conquest, military coups, and child soldiers. Moving beyond conventional questions of strategy, tactics, battles, and technology, historians of precolonial Africa are interested in the role of armies in state formation, the military activities of stateless societies, and armed encounters between Africans and foreign visitors and invaders. Scholars working in the 19th and 20th centuries are similarly focused on the role and influence of African soldiers, military women, and veterans in society. In this sense, African military history is part of a larger effort to recover the lived experiences of ordinary people who were largely missing from colonial archives and documentary records. Similarly, Africanist historians focusing on the national era are engaging older journalistic and social science explanations for military coups, failed states, and wardlordism. The resulting body of literature productively offers new ways to study military institutions and collective violence in Africa.
Film and Video as Historical Sources
Authors: Şaul Mahir
Published: November 2018

Films and video dramas can become historical sources in different ways. One of them is the use of the filmic images as a source for learning about the physical environment, the layout and look of cities, buildings, rural landscapes, and other cultural elements. The documentation of urban spaces in movies made in the cities that were frequently used as filming locations, such as Dakar in Senegal or Ouagadougou in Burkina Faso, furnish cases for extended treatment. Secondly, feature films can comment on the past as a kind of “history writing,” by offering explanation and perspective on past events, a means of doing what written history does in a different medium. The invention of fictional characters or dialogue and filmic strategies such as condensation do not invalidate the contribution that some movies make to the understanding of historical situations. In the case of African history, films by Ousmane Sembene, Med Hondo, and Raoul Peck are illustrations of how this has been achieved. Finally, movies also bear witness to the time of their production, because as creations of the intellect they reflect the interests, concerns, preoccupations, and possibilities of their time. Studies can focus not only on a movie in itself but also on viewers’ perception of it or on critics’ responses, either at the time of its first release or in subsequent viewings. In contrasting ways, Gaston Kaboré’s pre-colonial era films and Jean-Pierre Bekolo’s depiction of Yaounde working class neighborhoods offer exemplary material for this kind of study. Popular films and video dramas can in turn have an impact on their societies and be used deliberately by their makers to disseminate messages, entering in this way the chain of historical causality. In the 1990s the low budget video dramas first produced in Ghana and Nigeria in analogue recordings on VHS cassettes brought a challenge to the established African cinema that was recognized in the international film festival circuit, by combining amateurish production values and commercial success. This mass cultural phenomenon offers an opportunity to explore the economic and cultural roots of a particular style of visual storytelling, as well as the connections between popular audiences’ thematic preferences in entertainment and their everyday living conditions.
The History and Historiography of Science
Authors: Tilley Helen
Published: November 2018

There is no escaping the fact that the history of science took European places and people, broadly construed, as its original object of study. There is also no escaping that in African history, scholars interested in science, technology, and to a lesser extent environmental knowledge have concentrated the bulk of their investigative energies on developments since European (and North African) conquest. This focus on the period since the 1870s has tended to foreground dynamics relating to colonial rule and state-building, extractive economies and development, and decolonization and geopolitics. A handful of Africanists in the history of science have explicitly worked to cross the colonial divide, often taking single topics deeper back in time. The field as a whole, however, still needs to debate more systematically what the overarching narratives and benchmark phenomena should be for the precolonial periods. It also needs to grapple more explicitly with methodological tensions that arise from a focus on human agency and specific places (and the languages this requires) versus a focus on ideas, tools, and phenomena that transcend local or state containers (and the trade-offs this produces). As historians of science extend their reach into Africa’s pasts and bridge the colonial and post-colonial divides, it raises thorny questions about different approaches. Among others this includes how we produce histories of science, why they matter, and what we ought to bear in mind as we do. To this end, four goals are advanced here simultaneously: First, is the aim to open a dialogue with historians of science working outside Africa about ways Africanist scholarship speaks to and could be incorporated into the field as a whole (encouraging non-Africanists to consider the blind spots of “global” histories). Second, is the objective to draw attention to the pitfalls and benefits of different research methods and theoretical assumptions, especially as they relate to expert knowledge (an analysis that may be most useful for students entering the field). Third, is the ambition to explore a set of topics that connect deeper time periods to more recent developments (topics that invite critical scrutiny from specialists and generalists alike). Finally, is the desire to foreground the many different ways people across sub-Saharan Africa have initiated, responded to, and been incorporated into the production of knowledge. Africa has been a site of rich and varied epistemological and material experiments for millennia—some deleterious, some beneficial, and all imbued with different kinds of power. Acknowledging this long-standing history can serve to correct stereotypes that suggest otherwise. It can also contribute to debates within the history of science as the field continues to move away from its original focus on Europe and Europeans.
African Philosophies of History and Historiography
Authors: Falola Toyin , Borah Abikal
Published: November 2018

Since the late 1950s, the field of African historiography has undergone many changes. While discussing African philosophies of history, one must acknowledge shifts within the discipline of history and the Afrocentric vision of historical scholarship as two constitutive processes through which different historiographical trends have come into being. It is difficult to take an essentialist position on African philosophies of history, because Africa has been at the center of various transnational and global processes of historical formation. As a result, the scope and scale of African historiography signals a variety of entanglements. The imperative lies in recognizing such entanglements in the longue durée of Africa’s past, to dislodge the narrowly framed imagination attached to African historiography. Considering the complexity of the terrain, it would be appropriate to view African philosophies of history and historiography from three different vantage points. Firstly, historical scholarship centering on Africa has produced critiques of the post-Enlightenment philosophy of history in Europe and elsewhere. This strand highlights the interventions posed by African historiography that decenter a globalized philosophical tradition. Secondly, the inclusion of African indigenous epistemological formations into historical scholarship has transformed the scope of African historiography. This shows shifts in the methodological approaches of historical scholarship and highlights the question of access to the multiplicity of Africa’s past. Thirdly, Pan-Africanism and Afropolitanism expanded the scope and scale of the African philosophy of history by thinking through the transnational and global connections of Afrocentric thought. In other words, Afrocentric historiography attends to the ideas of globalism and cosmopolitanism within its scope and scale.
Legal History and Historiography in Colonial Sub-Saharan Africa
Authors: Waller Richard
Published: November 2018

Increasingly, the study of law in colonial Africa has moved out of the domain of legal scholarship per se, where it had its origins in the 1940s, and into that of social and cultural history; it has also shifted from a rules-based approach, primarily concerned with legal codes and judicial institutions, to one that focuses on process and explores the complex relationship between law and culture. As the field has expanded, it has divided into sub-branches. Some remain within the scope of legal history, defined as the study of how legal codes and judicial procedures have developed and changed and of the issues of principle that arose; others are more concerned with the social impact of law, how the establishment of colonial legal regimes, including customary law and the courts where cases could be heard, presented new dilemmas and opportunities and altered the distribution of power in African communities. Beyond this, historians have also used legal records, especially court records, as social documents without being directly concerned with their particular legal and judicial contexts. Once their limitations and the difficulties of interpretation that they present have been understood, such records offer potentially rich insights into family and household affairs as well as into more obviously civil or criminal matters.
Environmental History
Authors: Kreike Emmanuel
Published: November 2018

Environmental history highlights the dynamic interaction between the physical environment and human society, respectively framed as nature and culture. Attributing agency to the environment is perhaps the most distinguishing attribute of environmental history as an approach while human society’s struggle to overcome environmental challenges is a major focus of environmental historians. Generally, students of the African past have tended to emphasize that Africa and Africans were more dependent on nature (including climate, geography, natural resources, “natural” population dynamics, disease) than societies elsewhere, especially those in the modern West. Thus, colonial and postcolonial analysts ascribe Africa’s past as the cradle of the human species, its present lack of political and economic development, and its bleak future in an age of climate change not to any African (or human) genius but to the caprices of an undomesticated environment and interventions by outside actors that disturb an environment-people balance. Historians emphasized that political subjugation, agricultural development, and conservation increased African societies’ vulnerability (to malnutrition, drought, and indigenous and exotic diseases, for example) in the face of environmental change because it enclosed and alienated such key natural resources as land, woodlands, wildlife, and water. More recently, historians of Africa have highlighted a more dynamic and interactive relationship between society and environment in Africa beyond the analytical and nested dichotomies of Nature-Culture, Indigenous-Invasive, and Victim/Subaltern-Perpetrator/Ruler. The perspective opens space for considering how societies perceived and shaped their environments physically and mentally in conjunction with other ideas and forces, including a variety of human and non-human agents, further enriching the study of environmental history.
Seaport Cities in North America, 1600–1800
Authors: Hart Emma
Published: November 2018

Since many North American indigenous societies also built and inhabited towns, America was not an entirely rural continent before the arrival of Europeans. Nevertheless, when Europeans set out to colonize their “wilderness,” they arrived with a practical and ideological commitment to recreating cities of the sort with which they were familiar on their home continent. The result of their ambitions was the rapid founding and development of European-style cities, the vast majority of which clustered on large bodies of water, either directly on the Atlantic Ocean or on the seas and river estuaries adjacent to it. The pace of city expansion was closely linked to the levels of support for cities among colonists and an economic environment that stimulated urban growth. Some cities grew faster than others, but by the middle of the 18th century even Virginia and Maryland, the most rural colonies, had towns that played a critical cultural, political, and economic role in society. By the revolutionary era, the centrality of North America’s seaports was cemented by their status as crucibles of the conflict. The issue of which seaport was the new United States’ premier city was contested, but the importance of cities to North American society was no longer debated.
How to Make Individual Transferable Quotas Work Economically, Socially, and Environmentally
Authors: Sumaila Rashid
Published: November 2018

The economic tool of individual transferable quotas (ITQs) gives their owners exclusive and transferable rights to catch a given portion of the total allowable catch (TAC) of a given fish stock. Authorities establish TACs and then divide them among individual fishers or firms in the form of individual catch quotas, usually a percentage of the TAC. ITQs are transferable through selling and buying in an open market. The main arguments by proponents of ITQs is that they eliminate the need to “race for the fish” and thus increase economic returns while eliminating overcapacity and overfishing. In general, fisheries’ management objectives consist of ecological (sustainable use of fish stocks), economic (no economic waste), and social (mainly the equitable distribution of fisheries benefits) issues. There is evidence to show that ITQs do indeed reduce economic waste and increase profits for those remaining in fisheries. However, they do not perform well in terms of sustainability or socially. A proposal that integrates ITQs in a comprehensive and effective ecosystem-based fisheries management system that is more likely to perform much better than ITQs with respect to ecological, economic, and social objectives is presented in this article.
Deforestation: Drivers, Implications, and Policy Responses
Authors: Runyan Christiane W. , Stehm Jeff
Published: November 2018

Over the last 8,000 years, cumulative forest loss amounted to approximately 2.2 billion hectares, reducing forest cover from about 47% of Earth’s land surface to roughly 30% in 2015. These losses mostly occurred in tropical forests (58%), followed by boreal (27%) and temperate forests (8%). The rate of loss has slowed from 7.3 Mha/year between 1990–2000 to 3.3 Mha/year between 2010–2015. Globally since the 1980s, the net loss in the tropics has been outweighed by a net gain in the subtropical, temperate, and boreal climate zones. Deforestation is driven by a number of complex direct and indirect factors. Agricultural expansion (both commercial and subsistence) is the primary driver, followed by mining, infrastructure extension, and urban expansion. In turn, population and economic growth drive the demand for agricultural, mining, and timber products as well as supporting infrastructure. Population growth and changing consumer preferences, for instance, will increase global food demand 50% by 2050, possibly requiring a net increase of approximately 70 million ha of arable land under cultivation. This increase is unlikely to be offset entirely by agricultural intensification due to limits on yield increases and land quality. Deforestation is also affected by other factors such as land tenure uncertainties, poor governance, low capacity of public forestry agencies, and inadequate planning and monitoring. Forest loss has a number of environmental, economic, and social implications. Forests provide an expansive range of environmental benefits across local, regional, and global scales, including: hydrological benefits (e.g., regulating water supply and river discharge), climate benefits (e.g., precipitation recycling, regulating local and global temperature, and carbon sequestration), biogeochemical benefits (e.g., enhancing nutrient availability and reducing nutrient losses), biodiversity benefits, and the support of ecosystem stability and resiliency. The long-term loss of forest resources also negatively affects societies and economies. The forest sector in 2011 contributed roughly 0.9% of global GDP or USD 600 billion. About 850 million people globally live in forest ecosystems, with an estimated 350 million people entirely dependent on forest ecosystems for their livelihoods. Understanding how to best manage remaining forest resources in order to preserve their unique qualities will be a challenge that requires an integrated set of policy responses. Developing and implementing effective policies will require a better understanding of the socio-ecological dynamics of forests, a more accurate and timely ability to measure and monitor forest resources, sound methodologies to assess the effectiveness of policies, and more efficacious methodologies for valuing trade-offs between competing objectives.
Directional allelic imbalance profiling and visualization from multi-sample data with RECUR
Authors: Jakubek Yasminka A , San Lucas F Anthony , Scheet Paul
Published: November 2018

Motivation

Genetic analysis of cancer regularly includes two or more samples from the same patient. Somatic copy number alterations leading to allelic imbalance (AI) play a critical role in cancer initiation and progression. Directional analysis and visualization of the alleles in imbalance in multi-sample settings allow for inference of recurrent mutations, providing insights into mutation rates, clonality and the genomic architecture and etiology of cancer.

Results

The REpeat Chromosomal changes Uncovered by Reflection (RECUR) is an R application for the comparative analysis of AI profiles derived from SNP array and next-generation sequencing data. The algorithm accepts genotype calls and ‘B allele’ frequencies (BAFs) from at least two samples derived from the same individual. For a predefined set of genomic regions with AI, RECUR compares BAF values among samples. In the presence of AI, the expected value of a BAF can shift in two possible directions, reflecting an increased or decreased abundance of the maternal haplotype, relative to the paternal. The phenomenon of opposite haplotype shifts, or ‘mirrored subclonal allelic imbalance’, is a form of heterogeneity, and has been linked to clinico-pathological features of cancer. RECUR detects such genomic segments of opposite haplotypes in imbalance and plots BAF values for all samples, using a two-color scheme for intuitive visualization.

Availability and implementation

RECUR is available as an R application. Source code and documentation are available at scheet.org.

TAIJI: approaching experimental replicates-level accuracy for drug synergy prediction
Authors: Li Hongyang , Hu Shuai , Neamati Nouri , Guan Yuanfang
Published: November 2018

Motivation

Combination therapy is widely used in cancer treatment to overcome drug resistance. High-throughput drug screening is the standard approach to study the drug combination effects, yet it becomes impractical when the number of drugs under consideration is large. Therefore, accurate and fast computational tools for predicting drug synergistic effects are needed to guide experimental design for developing candidate drug pairs.

Results

Here, we present TAIJI, a high-performance software for fast and accurate prediction of drug synergism. It is based on the winning algorithm in the AstraZeneca-Sanger Drug Combination Prediction DREAM Challenge, which is a unique platform to unbiasedly evaluate the performance of current state-of-the-art methods, and includes 160 team-based submission methods. When tested across a broad spectrum of 85 different cancer cell lines and 1089 drug combinations, TAIJI achieved a high prediction correlation (0.53), approaching the accuracy level of experimental replicates (0.56). The runtime is at the scale of minutes to achieve this state-of-the-field performance.

Availability and implementation

TAIJI is freely available on GitHub (https://github.com/GuanLab/TAIJI). It is functional with built-in Perl and Python.

Impact of H1N1 Influenza Vaccination on Child Morbidity in Guinea-Bissau
Authors: Hansen Olga Bengård , Rodrigues Amabelia , Martins Cesario , Rieckmann Andreas , Benn Christine Stabell , Aaby Peter , Fisker Ane Bærent
Published: November 2018

Background

In addition to vaccines’ specific effects, vaccines may have non-specific effects (NSEs) altering the susceptibility to unrelated infections. Non-live vaccines have been associated with negative NSEs. In 2010, a campaign with the non-live H1N1-influenza vaccine targeted children 6–59 months in Guinea-Bissau.

Methods

Bandim Health Project runs a health and demographic surveillance system site in Guinea-Bissau. Using a Cox proportional hazards model, we compared all-cause consultation rates after vs. before the campaign, stratified by participation status.

Results

Among 10 290 children eligible for the campaign, 60% had participated, 18% had not and for 22% no information was obtained. After the H1N1 campaign, the consultation rates tended to decline less for participants [HR = 0.80 (95% confidence interval, CI: 0.75; 0.85)] than for non-participants [HR = 0.68 (95% CI: 0.58; 0.79)], p = 0.06 for same effect.

Conclusion

The decline in the vaccinated group may have been smaller than the decline in the non-vaccinated group consistent with H1N1-vaccine increasing susceptibility to unrelated infections.
Spinach Downy Mildew: Advances in Our Understanding of the Disease Cycle and Prospects for Disease Management
Authors: Kandel Shyam L. , Mou Beiquan , Shishkoff Nina , Shi Ainong , Subbarao Krishna V. , Klosterman Steven J.
Published: November 2018

Downy mildew on spinach is caused by Peronospora effusa, an oomycete pathogen that poses a challenge to spinach production worldwide, especially in organic production. Following infection, P. effusa produces abundant amounts of asexual sporangia. Sporangia become windborne and initiate new infections locally or distantly, leading to widespread epidemics. Oospores produced from the union of opposite mating types have been observed within infected leaves and seeds and may remain viable for many years. Sexual reproduction increases the genetic diversity of P. effusa through sexual recombination, and thus, the movement of oospores on seed has likely fueled the rapid explosion of new pathotypes in different regions of the world over the past 20 years. This review summarizes recent advances in spinach downy mildew research, especially in light of the findings of oospores in contemporary commercial spinach seed lots as well as their germination. Knowledge of the role of the oospores and other aspects of the disease cycle can directly translate into new and effective disease management strategies.

Published: November 2018

The skin is home to an important part of our commensal microbiota, despite it being a cool, acidic and desiccated environment. Tailored microbiome modulation approaches with, for example probiotics, are highly challenging for this body site. Here we show by next-generating sequencing that Lactobacillus taxa -especially those known to be dominant in the human vagina- are underestimated members of the skin microbiota. Specific Lactobacillus strains were selected in the lab and formulated in a viable form in an oil in water-based topical cream. Facial application by patients with mild-to-moderate acne symptoms was able to reduce inflammatory lesions and comedone formation. This was associated with a temporary modulation of the skin microbiome, including a reduction in relative abundance of staphylococci and an increase in lactobacilli. Skin microbiome modulation by addition of carefully formulated lactobacilli seems to be new therapeutic option to reduce antibiotic use for common acne symptoms.
Reproduction and longevity A Mendelian randomization study of gonadotropin-releasing hormone and ischemic heart disease
Authors: Schooling C M , Ng Jack C M
Published: November 2018

Background

According to well-established evolutionary biology theory reproduction trades-off against longevity, implying that upregulating the reproductive axis might drive major diseases. We assessed whether the central driver of reproduction gonadotropin-releasing hormone 1 (GnRH1) had a causal effect on the leading cause of global morbidity and mortality, i.e. ischemic heart disease (IHD). As a contrast we similarly examined the role of GnRH2 because it is more a driver of female sexual behavior.

Methods

We applied strong (p-value <5×10−6) and independent genetic predictors of GnRH1 and GnRH2 to an extensively genotyped IHD case (n=76,014) - control (n=264,785) study using multiplicative random effects inverse variance weighted (IVW), weighted median, MR-Egger and MR-PRESSO estimates.

Results

GnRH1, predicted by 11 genetic variants, was positively associated with IHD (IVW odds ratio (OR) 1.04 per effect size, 95% confidence interval (CI) 1.01 to 1.08), but GnRH2, predicted by 15 genetic variants, was not (IVW OR 0.98, 95% CI 0.95 to 1.02).

Conclusions

GnRH1 is a potential IHD genetic target. Apart from demonstrating a central tenet of evolutionary biology in humans, our study suggests that existing treatments and environmental factors targeting GnRH1, its drivers or consequences could be re-purposed to prevent and treat IHD. Given, the importance of reproduction to the human species, many such exposures likely exist.
Age but not disease progression defines CD4+ and CD8+ T stem cell memory levels in human retroviral infections: contrasting effects of HTLV-1 and HIV-1
Authors: Menezes Soraya Maria , Leal Fabio Eudes , Ribeiro Susan Pereira , Dierckx Tim , Roederer Mario , SenGupta Devi , Nixon Douglas F. , Van Weyenbergh Johan
Published: November 2018

Background

Human CD4+ and CD8+ stem cell memory T cells (TSCM) represent a minor fraction of circulating lymphocytes characterized by stemness and long-term in vivo persistence. CD4+ TSCM are preferentially infected and constitute a reservoir for HIV-1, whereas CD8+ TSCM appear to play a protective role. However, little is known about CD4+ and CD8+ TSCM in the only other human pathogenic retroviral infection, human T-cell leukemia virus type 1 (HTLV-1). HTLV-1 is the etiological agent of both Adult T-cell Leukemia (ATL) and HTLV-1 associated myelopathy/tropical spastic paraperesis (HAM/TSP), a neuroinflammatory disorder. In ATL, CD4+ TSCM cells were identified as the hierarchical leukemic stem cell, but data in HAM/TSP are lacking. Age is a major risk factor for both ATL and HAM/TSP, as both diseases generally manifest several decades after infection. Therefore, we explored a possible link between TSCM, age and disease status in human retroviral infections in a cross-sectional study, using multiparametric flow cytometry.

Results

We found that CD4+ or CD8+ TSCM levels (quantified as CD3+CD45RA+CD45RO− CD27+CCR7+Fashi) do not differ between healthy controls and untreated HTLV-1 infected individuals with and without neuroinflammatory disorder. However, we found both TSCM as well as CD8+ TSCM significantly accumulated with age, resulting in a >400% increase in elderly HTLV-1 infected individuals (>60 years). A significant correlation between age and TSCM signature genes was validated at the transcriptome level in an independent cohort. CD8+ but not CD4+ TSCM were significantly decreased in untreated HIV-1 infection. Unexpectedly, CD8+ TSCM recovery upon successful antiretroviral treatment was essentially complete (92.2±11.0%) in younger (<45 years) individuals, but significantly lower (37.3±6.1%) in older (>45 years) individuals (p=0.0003).

Conclusion

In HTLV-1 infection, an age-dependent accumulation of CD4+ and CD8+ TSCM points towards a possible protective role of CD8 TSCM in the elderly against leukemic but not neuroinflammatory disease. HIV-1-infected individuals lose their ability to restore CD8+ TSCM levels upon successful antiretroviral therapy at later age (>45 years), which might eventually lead to immunological failure and decreased vaccine efficacy.
Harmful algae bloom monitoring via a sustainable, sail-powered mobile platform for in-land and coastal monitoring
Authors: Beckler Jordon S. , Arutunian Ethan , Currier Bob , Milbrandt Eric , Duncan Scott
Published: November 2018

Harmful algae blooms (HAB) in coastal marine environments are increasing in number and duration, pressuring local resource managers to implement mitigation solutions to protect human and ecosystem health. However, insufficient spatial and temporal observations create uninformed management decisions. In order to better detect and map blooms, as well as the environmental conditions responsible for their formation, long-term, unattended observation platforms are desired. In this article, we describe a new cost-efficient, autonomous, mobile platform capable of accepting several sensors that can be used to monitor harmful algae blooms in near real-time. The Navocean autonomous sail-powered surface vehicle is deployable by a single person from shore, capable of waypoint navigation in shallow and deep waters, and powered completely by renewable energy. We present results from three surveys of the Florida Red Tide harmful algae bloom (Karenia brevis) of 2017-2018. The vessel made significant progress towards waypoints regardless of wind conditions while underway chl.ameasurements revealed HAB bloom patches and CDOM and turbidity provided environmental contextual information. While the autonomous sailboat directly adds to our HAB monitoring capabilities, the boat can also help to ground-truth and thus improve satellite monitoring of HABs. Finally, several other pending and future use cases for coastal and inland monitoring are discussed. To our knowledge, this is the first demonstration of a sail-driven vessel used for coastal HAB monitoring.
The expendable male hypothesis
Authors: Mattison Siobhán M. , Quinlan Robert J. , Hare Darragh
Published: November 2018

Matriliny is a system of kinship in which descent and inheritance are conferred along the female line. The theoretically influential concept of the matrilineal puzzle posits that matriliny poses special problems for understanding men’s roles in matrilineal societies. Ethnographic work describes the puzzle as the tension experienced by men between the desire to exert control over their natal kin (i.e., the lineage to which they belong) and over their affinal kin (i.e., their spouses and their biological children). Evolutionary work frames the paradox as one resulting from a man investing in his nieces and nephews at the expense of his own biological offspring. In both cases, the rationale for the puzzle rests on two fundamental assumptions: (i) that men are always in positions of authority over women and over resources; and (ii) that men are interested in the outcomes of parenting. In this paper, we posit a novel hypothesis that suggests that certain ecological conditions render men expendable within local kinship configurations, nullifying the above assumptions. This arises when (i) women, without significant assistance from men, are capable of meeting the subsistence needs of their families; and (ii) men have little to gain from parental investment in children. We conclude that the expendable male hypothesis may explain the evolution of matriliny in numerous cases, and by noting that female-centered approaches that call into doubt assumptions inherent to male-centered models of kinship are justified in evolutionary perspective.
Prolactin Receptor Signaling Regulates a Pregnancy-Specific Transcriptional Program in Mouse Islets
Authors: Pepin Mark E. , Wende Adam R. , Banerjee Ronadip R.
Published: November 2018

Pancreatic β-cells undergo profound hyperplasia during pregnancy to maintain maternal euglycemia. Failure to reprogram β-cells into a more replicative state has been found to underlie susceptibility to gestational diabetes mellitus (GDM). We recently identified a requirement for prolactin receptor (PRLR) signaling in the metabolic adaptations to pregnancy, where mice lacking β-cell PRLR (βPRLRKO) exhibit a metabolic phenotype consistent with GDM. However, the underlying transcriptional program that is responsible for the PRLR-dependent metabolic adaptations during gestation remains incompletely understood. To identify PRLR signaling gene regulatory networks and target genes within β-cells during pregnancy, we performed a transcriptomic analysis of pancreatic islets isolated from either βPRLRKO mice or littermate controls in late gestation. Gene set enrichment analysis identified Forkhead box protein M1 (Foxm1) and polycomb repressor complex 2 (PRC2) subunits, Suz12 and Ezh2, as novel candidate regulators of PRLR-dependent β-cell adaptation. GO-term pathway enrichment revealed both established and novel PRLR signaling target genes that together describe a state of increased cellular metabolism and/or proliferation. In contrast to the requirement for β-cell PRLR signaling in maintaining euglycemia during pregnancy, PRLR target genes were not induced following high-fat-diet feeding. Altogether, the current study expands our understanding of which transcriptional regulators and networks mediate gene expression required for islet adaptation during pregnancy. The current work also supports the presence of pregnancy-specific adaptive mechanisms distinct from those activated by nutritional stress.
Analysis of influencing factors of Chinese provincial carbon emissions based on projection pursuit model and Markov transfer matrix
Authors: Wen Lei , Huang Linlin
Published: November 2018

Purpose

Climate change has aroused widespread concern around the world, which is one of the most complex challenges encountered by human beings. The underlying cause of climate change is the increase of carbon emissions. To reduce carbon emissions, the analysis of the factors affecting this type of emission is of practical significance.

Design/methodology/approach

This paper identified five factors affecting carbon emissions using the logarithmic mean Divisia index (LMDI) decomposition model (e.g. per capita carbon emissions, industrial structure, energy intensity, energy structure and per capita GDP). Besides, based on the projection pursuit method, this paper obtained the optimal projection directions of five influencing factors in 30 provinces (except for Tibet). Based on the data from 2000 to 2014, the authors predicted the optimal projection directions in the next six years under the Markov transfer matrix.

Findings

The results indicated that per capita GDP was the critical factor for reducing carbon emissions. The industrial structure and population intensified carbon emissions. The energy structure had seldom impacted on carbon emissions. The energy intensity obviously inhibited carbon emissions. The best optimal projection direction of each index in the next six years remained stable. Finally, this paper proposed the policy implications.

Originality/value

This paper provides an insight into the current state and the future changes in carbon emissions.
Website traffic measurement and rankings: competitive intelligence tools examination
Authors: Prantl David , Prantl Martin
Published: November 2018

Purpose

The purpose of this paper is to examine and verify the competitive intelligence tools Alexa and SimilarWeb, which are broadly used for website traffic data estimation. Tested tools belong to the state of the art in this area.

Design/methodology/approach

The authors use quantitative approach. Research was conducted on a sample of Czech websites for which there are accurate traffic data values, against which the other data sets (less accurate) provided by Alexa and SimilarWeb will be compared.

Findings

The results show that neither tool can accurately determine the ranking of websites on the internet. However, it is possible to approximately determine the significance of a particular website. These results are useful for another research studies which use data from Alexa or SimilarWeb. Moreover, the results show that it is still not possible to accurately estimate website traffic of any website in the world.

Research limitations/implications

The limitation of the research lies in the fact that it was conducted solely in the Czech market.

Originality/value

Significant amount of research studies use data sets provided by Alexa and SimilarWeb. However, none of these research studies focus on the quality of the website traffic data acquired by Alexa or SimilarWeb, nor do any of them refer to other studies that would deal with this issue. Furthermore, authors describe approaches to measuring website traffic and based on the analysis, the possible usability of these methods is discussed.
Job satisfaction in developing countries
Authors: Anh Nguyen , Nguyen Ngoc-Minh Thi , Tuong Anh Nguyen Thi , Nguyen Phuong Mai Thi
Published: November 2018

Purpose

The purpose of this paper is to contribute to this literature on developing countries by investigating the determinants of job satisfaction in Vietnam where the economics literature on this issue is virtually non-existent. The authors also contribute to the literature on income comparison by extending beyond the within-firm co-worker income comparison.

Design/methodology/approach

The authors estimate a generalized order logit model for job satisfaction as statistical tests suggest that the parallel-lines assumption, which is often invoked in previous studies using the standard logit model, does not hold.

Findings

For Vietnam, the authors find that absolute and relative incomes as well as human resource practices such as efficiency wage and training policy have an impact on workers’ satisfaction. Workers in the foreign direct investment (FDI) sectors behave a bit differently from their peers in the domestic sector.

Originality/value

Taking advantage of a unique matched employer–employee data set collected in 2008 by the North-South Institute (Canada) and the Vietnam Academy of Social Sciences, the authors are able to investigate the impact of a number of important job characteristics on job satisfaction such as absolute and reference incomes, wage policy, training plan for workers, union membership and job position, and, at the same time, to disentangle the possible differences in job satisfaction of workers in domestic vs FDI firms.
Emotional intelligence in a neoclassical framework and the nature of capitalism
Authors: Soldatos Gerasimos T. , Varelas Erotokritos
Published: November 2018

Purpose

The purpose of this paper is to introduce the factor of emotional intelligence (EI) into the calculus of neoclassical analysis under precautionary saving aiming at stabilizing consumption in the case of an exogenous output shock.

Design/methodology/approach

The introduction of EI differentiates individual firms in handling production uncertainty and individual consumers in coping with consumption uncertainty, but the source of uncertainty is exogenous and affects all the same; there are no idiosyncratic risks and uncertainties. This in conjunction with the median-voter-theory like approach to agent heterogeneity prompted by EI, replicates the result that aggregates quantitative predictions are almost indistinguishable from their representative agent counterpart in life cycle models of precautionary saving.

Findings

EI corroborates stabilization greatly but only the introduction of a monetary authority would fully stabilize the system by injecting or withdrawing money depending on the state of the economy. Money becomes centrally issued and it would be destabilizing if it was accompanied by central and/or commercial bank seigniorage. Median EI is found to coincide with homo economicus' rationality. These results point to the importance of preserving the institutional character of capitalism as a free enterprise but also a competitive system under a government in the service of the private sector.

Originality/value

Methodologically, this paper acknowledges the mutual interdependence between human action and social structure in the liberal setting in which free enterprise is a socioeconomic process that identifies value through exchange under the sociopolitical process of democracy.
Early American and Contemporary European Conceptions of the Nation, 1763–1789
Authors: KOSTANTARAS DEAN
Published: November 2018

This article examines how the term ‘nation’ was used in texts originating from North America immediately before and after the revolution, as well as notable omissions. Colonial authors often referred, for example, to nations, however allusions to an ‘American nation’ were rare, and indeed are wholly absent from such fundamental works as the Declaration of Independence and Articles of Confederation. These tendencies, it is argued throughout, reflect the important influence of broader international trends in thought – some of which have not been adequately documented in previous treatments of the subject – on local usages and self‐understandings. When such texts are put into conversation with works from across the Atlantic, one gains not only a clearer picture of colonial sensibilities and aims, but the manner in which their conceptual repertoire was informed by a larger Anglo‐European traffic in ideas.
Land and housing as crucibles of racist nationalism: Asian Australians' experiences
Authors: Dunn Kevin M. , Blair Kathleen , Bliuc Ana‐Maria , Kamp Alanna
Published: November 2018

Nationwide surveys in 2015–16 in Australia collected data on experiences of racism in various spheres of everyday life, including housing. Of 6,001 respondents, 843 were of an Asian birthplace or background, and 638 spoke an Asian language. These Asian Australians had double the rate of experience of racism than had other Australians, in the form of racist mistrust, disrespect, and name‐calling (70% vs 35%). When renting or buying a house, almost six in ten (58%) Asian‐born participants had experienced discrimination to some extent because of their culture or religion. While 81 per cent of non‐Asian Australians report there is no racism in housing, the proportion reporting this among the Asian‐born participants was only 42 per cent. Those born in Australia but with Asian parents have the same exposure to racism, whereas those with only one parent born in Asia had an exposure closer to those with no Asian connection. “Racial” appearance plays a role in the racism experienced in relation to buying or renting housing. Racism in such a context limits Asian Australians' access to space and curtails the making of non‐Anglo place, which leads to the conclusion that land and housing are crucibles of racist nationalism.
Non‐reassuring results in agreement trial comparing glass and plastic capillary tubes for neonatal blood gas sampling
Authors: Tanney Kristin , Mahaveer Ajit , Dockery Karen , Booth Nicola , Chadwick Carol A. , Chaloner Chris M. , Rajai Azita
Published: November 2018

Aim

To determine agreement between neonatal capillary blood gases taken with plastic and glass tubes.

Methods

An agreement study was carried out in a regional tertiary neonatal unit. Inpatient babies ≥1 kg were recruited to the study when parents gave consent. After taking the routine glass capillary tube sample, a plastic tube sample was taken and run if the heel continued to bleed. Successful sample pairs were recorded and analysed against pre‐defined acceptable differences. Assessment was also made of differences in failure rates between tube types for each parameter.

Results

Twenty‐eight babies provided 135 blood gas pairs, of which five pairs were excluded. Successful pairing of results was achieved for pH in 105 valid samples. There were more failed plastic samples than glass, reaching significance for almost all parameters. pH, pO2 and pCO2 showed poor agreement (<80%) between glass and plastic tubes. On limited analysis of one successful blood gas pair per neonate to minimise bias, results remained non‐reassuring.

Conclusion

The findings of this study do not advocate switching from glass to plastic capillary tubes in our Newborn Intensive Care Unit. Further studies are required to assess agreement of glass and plastic capillary tubes for neonatal blood gas sampling.
Influence of climate, post‐treatment weather extremes, and soil factors on vegetation recovery after restoration treatments in the southwestern US
Authors: Copeland Stella M. , Munson Seth M. , Bradford John B. , Butterfield Bradley J.
Published: November 2018

Aims

Understanding the conditions associated with dryland vegetation recovery after restoration treatments is challenging due to a lack of monitoring data and high environmental variability over time and space. Tracking recovery trajectories with satellite‐based vegetation indices can strengthen predictions of restoration outcomes across broad areas with varying environmental conditions.

Location

Southwestern United States.

Methods

We quantified the recovery trajectories of spring and summer soil‐adjusted total vegetation index (SATVI) for 5–10 year periods following post‐wildfire seeding or prescribed burns for 241 treatment sites and related SATVI to ground‐based vegetation cover. We modeled SATVI based on time since treatment, yearly temperature and precipitation, weather extremes following treatment, soil available water capacity, invasive species presence, and treatment type. We also tested for the effects of environmental variables on trajectories, by examining interactions with years post‐treatment.

Results

Ground‐based vegetation cover and SATVI were highly correlated. Most treatment sites had positive recovery rates for spring (82%) and summer (85%) SATVI. Several environmental variables affected vegetation recovery trajectories as indicated by interactions with time since treatment. Yearly warm season precipitation had a positive effect on SATVI recovery that increased over time, whereas the positive effect of extreme high warm season precipitation following treatment decreased over time for both seasons of vegetation measurements. For spring SATVI, the positive effect of cool season yearly precipitation increased over time while the negative effect of extreme high temperatures following treatment became more negative over time. Invasive species presence led to higher spring, but not summer, SATVI.

Conclusions

Satellite‐based remote sensing is a promising tool to assess vegetation recovery following restoration treatments, particularly when it is combined with ground‐based monitoring. Our results suggest that weather extremes following restoration treatments can affect vegetation recovery trajectories and may be considered in management decisions such as the timing of restoration treatments.
Agricultural economics: Key commitments and institutional alertness
Authors: James Deaton B.
Published: November 2018

This presidential address highlights the foundational and ongoing importance of the historical commitments of agricultural economists to applied research and outreach programs. In addition, I stress that institutional alertness increases the pragmatic approach. When research, extension, and institutional alertness are fully integrated, agricultural economists have the potential to generate grounded knowledge, which has meaningful implications to our effort to improve life. I develop these ideas generally and with specific reference to my own research.
