On the long‐term prospects of power‐to‐gas technologies
Authors: Ajanovic Amela , Haas Reinhard 
Published: July 2018

Electricity generation from variable renewable energy sources such as wind and solar has grown in some countries at such a high rate that long‐term storage becomes relevant. The main rationale of power‐to‐gas (P2G) conversion of excess power is that the capacity of the gas pipelines and gas storage is much higher than that of the electricity transmission lines. This paper investigates the market prospects of hydrogen and methane from P2G conversion as a long‐term electricity storage option. Of specific interest is the future development of investment costs, economies‐of‐scale, the impact of the electricity price, and its distribution as well as possible locations. We conclude that from an economic point‐of‐view, the future prospects of all P2G technologies are much less promising than currently indicated in several papers and discussions. It will become very hard for P2G to compete in the electricity markets despite a high technological learning potential. However, for both hydrogen and methane, there are prospects for use in the transport sector. Already today compressed gas vehicles are by and large competitive.This article is categorized under:

Law and Economic Growth in China: A Case-Study of the Stock Market
Authors: ZHANG Zhong 
Published: July 2018

AbstractIt is widely accepted that law is essential for economic growth. Prominent economists in China have repeatedly called for strengthening the legal system so that the economy can continue to grow. Nevertheless, the fact that China has been able to achieve rapid economic growth while the law is weak seems to cast doubt on the significance of law. It is even suggested that China is a counter-example to the importance of law and, more provocatively, it is argued that China’s economy grew rapidly not “in spite of,” but “because of,” weak law. To gain a richer and deeper understanding of law in China’s economic growth, this paper conducts a case-study of China’s stock market by examining its growth history and legal development. It is found that China has built from scratch a complex legal and regulatory system governing the stock market, which actually played a critical role in supporting the growth of the market. However, the trajectory of development was law following market growth, which was in turn caused by ideological and political liberalization. On the other hand, the market did not grow to its full potential and currently it faces serious challenges to fulfil the task of supporting the development of the economy, and the fundamental reason is political and ideological restrictions; likewise, the improvement of law for investor protection has not been sustained, for which similarly politics and ideologies offer an explanation. The experience of the stock market suggests that, while law is indispensable for sustaining China’s economic growth, political and ideological liberalization is fundamental in that it is not only necessary to free up the economy so that it can continue to grow in the first place, but also crucial to further strengthening the whole legal system.

AbstractObjectiveThe Florida Department of Health in Miami-Dade County (DOH-Miami-Dade) investigated 106 reported carbon monoxide (CO) exposures over a 9-day timeframe after Hurricane Irma. This report evaluates risk factors for CO poisoning and the importance of heightened surveillance following natural disasters.MethodsData on CO poisoning cases from September 9 to 18, 2017 were extracted from Merlin, the Florida Department of Health Surveillance System. Medical records were obtained and follow-up interviews were conducted to collect data on the confirmed CO poisoning cases. Data were analyzed using SAS v9.4.ResultsNinety-one of the 106 people exposed to CO met the case definition for CO poisoning: 64 confirmed, 7 probable, and 20 suspect cases. Eighty-eight percent of the affected individuals were evaluated in emergency departments and 11.7% received hyperbaric oxygen treatment. The most frequently reported symptoms included headache (53.3%), dizziness (50.7%), and nausea (46.7%). Three patients expired due to their exposure to CO.ConclusionsPost Hurricane Irma, the DOH-Miami-Dade investigated numerous cases for CO exposure. By understanding who is most likely to be impacted by CO and the impact of generators’ location on people’s health, education efforts can be tailored to the population most at risk and further CO exposures and related mortalities following natural disasters can be reduced.

African colonial soldiers, memories and imagining migration in Senegal in the twenty-first century
Authors: Mourre Martin 
Published: July 2018

AbstractThis article is an attempt to reconsider the representations that, in Senegal in the 2000s, linked the social history of thetirailleurs(African colonial soldiers) with the practical and symbolic processes at the heart of a number of migratory projects, especially among young people. The history of this social military body was rooted in almost a century of colonial domination, from 1857 to 1962. Thetirailleursplayed a part in all the battles of the French army and generated different kinds of social imaginaries that were woven between France and Africa. In the late 1950s, another figure, another ideal type, became established in the Senegalese public space: the migrant. After tracing the history of the way in which these two figures were constructed, I trace how, more recently, the younger generation has been able to mobilize the dominant memory of thetirailleurin its own aspirations of exile. Some preliminary methodological proposals will be needed to account for these migratory imaginaries.
Shifting memories and forced migrations: the Somali Zigula migration to Tanzania
Authors: Declich Francesca 
Published: July 2018

AbstractForced migrations, both now and in the past, imply a process of constructing and modifying accounts of past events, which become codified in memories. Memories are constructed to negotiate and reshape identity in the country of arrival. A number of factors interact in this process, some aspects are silenced and others emphasized, and new events may be invented. One of the arguments I make elsewhere is that, along the way, memories of the past, especially if gathered and codified through writing, may lose meanings that are unknown to the people who codify them. Yet, in times of forced migration, certain aspects of the memories re-emerge from the background and gain new relevance. This was the case, for instance, with matriliny and matrilineal names, which were not recognized or emphasized by those who codified certain oral traditions of migrations at specific historical times in written form in Somalia. Yet, in the process of seeking integration in Tanzania after the forced migration caused by the 1992 war in Somalia, these aspects regained their importance in Somali Zigula memories and helped to achieve inclusion in the country of migration. Zigula memories of the past have undergone some changes. The way in which these changes have occurred is not unique: the process of modelling memories of the past that are based on idioms of kinship follows specific patterns that are part of a specific culture of mobility. Based on fieldwork carried out with refugees forced to migrate from southern Somalia to Tanzania in the early 1990s, I show how their collective memories of past events took on newly gendered features when circumstances changed and the main spoken language progressively shifted from Kizigula to Kiswahili.
Animating ‘refugeeness’ through vulnerabilities: worthiness of long-term exile in resettlement claims among Somali refugees in Kenya
Authors: Ikanda Fred Nyongesa 
Published: July 2018

AbstractRefugees are generally viewed as a transitory problem. In many African countries, however, protracted refugee situations have turned the temporary refugee state into a more or less permanent phenomenon. In this article, I draw on the concept of uncertainty, and on claims that suspicion structures humanitarianism, to examine how long-term residents in Dagahaley refugee camp in Kenya attempted to make themselves worthy of being considered for resettlement. I demonstrate how the incompatibility between the UNHCR's resettlement criteria and Somali refugees’ lived realities provided both sets of actors with a resource: they used understandings of vulnerability as a means for making or denying resettlement claims. Refugeeness is a process of becoming, premised on how earlier arrivals deployed long-term suffering as a justification for being prioritized for resettlement. These dynamics resulted in the emergence of ‘new’ and ‘old’ refugee distinctions through which the meanings of vulnerability were redefined.
Comparison of nutrient profiling models for assessing the nutritional quality of foods: a validation study

Published: July 2018

AbstractNutrient profiling (NP) is a method for evaluating the healthfulness of foods. Although many NP models exist, most have not been validated. This study aimed to examine the content and construct/convergent validity of five models from different regions: Australia/New Zealand (FSANZ), France (Nutri-Score), Canada (HCST), Europe (EURO) and Americas (PAHO). Using data from the 2013 UofT Food Label Information Program (n15342 foods/beverages), construct/convergent validity was assessed by comparing the classifications of foods determined by each model to a previously validated model, which served as the reference (Ofcom). The parameters assessed included associations (Cochran–Armitage trend test), agreement (κstatistic) and discordant classifications (McNemar’s test). Analyses were conducted across all foods and by food category. On the basis of the nutrients/components considered by each model, all models exhibited moderate content validity. Although positive associations were observed between each model and Ofcom (allPtrend<0·001), agreement with Ofcom was ‘near perfect’ for FSANZ (κ=0·89) and Nutri-Score (κ=0·83), ‘moderate’ for EURO (κ=0·54) and ‘fair’ for PAHO (κ=0·28) and HCST (κ=0·26). There were discordant classifications with Ofcom for 5·3 % (FSANZ), 8·3 % (Nutri-Score), 22·0 % (EURO), 33·4 % (PAHO) and 37·0 % (HCST) of foods (allP<0·001). Construct/convergent validity was confirmed between FSANZ and Nutri-Scorev.Ofcom, and to a lesser extent between EUROv.Ofcom. Numerous incongruencies with Ofcom were identified for HCST and PAHO, which highlights the importance of examining classifications across food categories, the level at which differences between models become apparent. These results may be informative for regulators seeking to adapt and validate existing models for use in country-specific applications.

Stage-specific differential DNA methylation data analysis during human erythropoiesis in chromosome 16
Authors: Garoot Najyah A. , Kim Byung Guk 
Published: July 2018

AbstractPrevious studies have generated controversial findings regarding the correlation between DNA methylation in the human genome and gene expression. Some reports have indicated that promoter methylation is negatively correlated with gene expression levels; however, in some cases, a poor or positive correlation was reported. Most previous findings were based on general trends observed with whole-genome data analysis. Here, we present a novel chromosome-specific statistical analysis design of empirical Bayes differential tests for five phases of erythroid development. To better understand the common methylation patterns of differentially methylated regions (DMRs) during specific stages, we defined differential phases for each CpG locus, based on a maximum log2 fold change. Analyzing hypermethylated and hypomethylated CpG loci separately showed variations in methylation patterns during erythropoiesis in the gene body, promoter and enhancer regions. Hypomethylated DMRs showed stronger associations with erythroid-specific enhancers at the differentiation start phase and with exons in the intermediate phase. To investigate the hypomethylated DMRs further, transcription factor binding site-enrichment analysis was conducted. This analysis highlighted novel transcription factors during each differentiation stage that were not detected by previous differential methylation data analysis. In contrast, hypermethylated DMRs showed a consistent methylation pattern over the different genomic regions. Thus, a closer examination of DNA methylation patterns in a single chromosome during each developmental stage can contribute to verify the association nature between gene expression and DNA methylation.
Sense and Nonsense About the Single European Currency
Authors: Congdon Tim 
Published: July 2018

The project to introduce a single currency is the most daring step so far in European integration. Indeed, it can be correctly described as revolutionary. It is much more far-reaching than previous moves in this direction over the last 15 years, such as the harmonisation of regulations or the ending of exchange controls; it is intended not as an incremental advance, but as a complete transformation of Europe's financial arrangements.The audacity of the single currency project is the more striking, in that it is a “revolution from above” rather than a “revolution from below”. The driving force has not been popular dissatisfaction with the existing currency arrangements, but the integrationist ambition of certain members of the European élite, particularly the German Chancellor, the French President and the President of the European Commission. (The integrationist ambition appears to attach to the positions ex officio and to be quite unaffected by the particular individuals who currently fill them.) These members of the élite emphasize the political nature of the single currency project, not the economic benefits. For example, Chancellor Kohl has said that European economic and monetary union (EMU) should prevent future wars in Europe.
Europe: A Partnership or a Problem?
Authors: Rifkind Malcolm 
Published: July 2018

Dr D C Bowie (President, FASS): Good evening, ladies and gentlemen. On behalf of the Faculty of Actuaries Students' Society, I am delighted to welcome you all here this evening. As you are probably aware, this lecture forms part of the celebrations of the 150th anniversary of the actuarial profession in the United Kingdom, and that is something of which we are all very proud.The Students' Society itself is of course much younger than that, having been established only in 1920, but I suspect that there are a lot of students who cannot envisage a profession without students, without examinations, and it just seems too idyllic a world really to imagine a profession that did not have students doing battle with those examinations. So I am sure that the Students' Society has been around at least as long–certainly in spirit.
ANALYSING GROUP DIFFERENCES IN INTELLIGENCE USING THE PSYCHOMETRIC META-ANALYTIC METHOD OF CORRELATED VECTORS HYBRID MODEL: A REPLY TO WICHERTS (2018) ATTACKING A STRAWMAN

At War with Water: The Maoist state and the 1954 Yangzi floods
Authors: COURTNEY CHRIS 
Published: July 2018

AbstractThis article offers a critical reappraisal of the Maoist state's response to the 1954 Yangzi floods. It uses a variety of sources, including previously classified government reports and oral history testimony, to challenge the official narrative. It argues that, far from being a remarkable victory for the new government, the flood was a humanitarian catastrophe that caused almost 150,000 deaths. Government hydraulic policies were partly to blame, as the vast majority of disaster victims were located in rural areas that were flooded deliberately in order to protect cities. In addition to revealing the true scale of the flood, this article uses the disaster as a prism to examine the early Maoist state. The government's combative environmental policies turned disaster governance into a war on water. This approach had certain benefits, particularly in terms of organizing an effective urban relief campaign. Unfortunately, campaign politics fostered an atmosphere of distrust, which encouraged many citizens to resist disaster-prevention policies. The example of the 1954 flood reveals the profound impact that a political context can have upon the outcome of a supposedly natural disaster.
Policy Practitioners’ Accounts of Evidence-Based Policy Making: The Case of Universal Credit
Authors: MONAGHAN MARK , INGOLD JO 
Published: July 2018

AbstractThis paper draws on insider accounts from UK Department for Work and Pensions (DWP) officials to analyse the relationship between evidence and policy making at a time of rapid policy development relating to Universal Credit (UC). The paper argues, firstly, that evidence selection within the DWP was constrained by the overarching austerity paradigm, which constituted a Zeitgeist and had a significant bearing on the evidence selection and translation process, sharpening the focus of policy officials and analysts on the primacy of quantitative evidence when advising Ministers. Secondly, while methodological preferences (or an ‘evidence hierarchy’) impacted on evidence selection, this was not as significant as practitioners’ perceived capabilities to handle and develop evidence for policy. These capabilities were linked to departmental structures and constrained by political feasibility. Together, these dimensions constituted a significant filtration mechanism determining the kinds of evidence that were selected for policy development and those omitted, particularly in relation to UC. The paper contributes to debates about the contemporary role of evidence in policymaking and the potential of the relationship between future evidence production and use.
Qualitative exploration of the experiences of informal care-givers for dependent older adults in Mexico City

Published: July 2018

AbstractPopulation ageing and increasing prevalence of chronic diseases and their consequences, changes in family structure and a decrease in the potential pool of family care, increase the need for formal long-term care for older adults in Mexico, and the need to understand the experiences of informal care-givers and how this impacts their social, family and personal conditions. This study investigates the experience of informal care-givers of dependent older adults using a cross-sectional qualitative study with an ethnographic focus. Thematic analysis was performed. The study comprised 48 semi-structured interviews with care-givers of dependent older adults who are beneficiaries of an in-home medical programme in Mexico City. The average age of care-givers was 54.7 years (standard deviation = 13.1, range = 24–86) and 75 per cent (36) were women. Results show care-giving experiences are diverse and complex, and profoundly affect the care-giver's life in terms of emotional burden, health deterioration and adverse life conditions due to economic deprivation. They also revealed key aspects such as the need to improve communication between care-givers and health-care personnel, the need for training about specific care needs and opportunity costs incurred. This information can serve as a basis for generating support strategies that may be integrated into the in-home programme. It is essential to promote actions that consider the ‘dependent older adult–informal care-giver’ dyad, and that aim to reduce the care-giving burden.
Volunteering among Japanese older adults: how are hours of paid work and unpaid work for family associated with volunteer participation?
Authors: Kobayashi Erika , Sugihara Yoko , Fukaya Taro , Liang Jersey 
Published: July 2018

AbstractAs the population ages, older adults are increasingly expected to play multiple productive roles. This study examined how hours of paid or unpaid work were associated with volunteering among older Japanese. Data came from the 2012 National Survey of the Japanese Elderly, a nationwide survey of Japanese aged 60 and older (N = 1,324). We performed multinominal logistic regression analyses to predict volunteering (regular or occasional versus non-volunteer) based on hours of paid work and unpaid work for family consisting of sick/disabled care, grandchild care and household chores. Those who worked moderate hours were most likely to be a regular volunteer while working 150 hours or more per month had a lower probability of volunteering, regardless of whether the work was paid or unpaid. Thus, full-time level work competed with volunteering for both paid and unpaid work for family, but it was more so for paid work. By types of activities, doing household chores and substantial grandchild care were positively associated with volunteering, and the latter complementary relationship was explained by a larger community network among grandparents. Our findings indicate that delaying retirement from full-time paid work may reduce the supply of regular volunteers in the community. Thus, policies to increase part-time work for older adults as well as the types of volunteer work in which paid workers can participate are necessary.
