Long‐Term Change of Fish Communities in a Polluted Watershed: Does Cleaner Water “Act” on Fishes?
Authors: Whitney James E. , Holloway Joshua A. , Scholes Derek T. , King Alexandra D. 
Published: November 2018

AbstractPollution is a threat to lotic fishes that enter streams via point source (PS) and nonpoint source (NPS) pathways. The Clean Water Act (CWA) of 1972 and the Surface Mining Control and Reclamation Act (SMCRA) of 1977 reduced PS pollution in the United States, but little information is available concerning the response of fish communities to this legislation. The objectives of this research were to quantify the responses of fishes to the CWA and SMCRA in the Cow Creek watershed of southeastern Kansas, a wadeable stream network that experienced large reductions in PS pollution. Responses were quantified by measuring changes in site occupancy, relative abundance, and species richness across 25 sites sampled in 1963 and again in 2017. Responses were compared among fishes that were intolerant, moderately intolerant, moderately tolerant, and tolerant of pollution using an analysis of deviance coupled with general linear hypothesis testing. We predicted that intolerant fishes would exhibit the most dramatic increases in distribution and abundance and that these changes would be most evident in streams that were directly receiving PS pollution in 1963. However, our predictions were not met, as species tolerant of pollution exhibited greater occupancy, relative abundance, and richness than did intolerant fishes, regardless of time period. Contemporary pH and substrate composition were also quantified and revealed that most streams had recovered from historical acid mine drainage but were dominated by fine substrates. We hypothesized that the limited responses exhibited by intolerant fishes were at least partially attributable to NPS pollution (i.e., sedimentation) resulting from agriculture, which was the dominant land use both historically and currently. We conclude that reductions in both NPS pollution coupled with historical reductions in PS pollution may be necessary to increase the prevalence of intolerant fishes. These management actions may have conservation implications as many intolerant fishes are also imperiled.

AbstractConversion of biomass to chemicals provides essential products to human society from renewable resources. In this context, achieving atom‐economical and energy‐efficient conversion with high selectivity towards target products remains a key challenge. Recent developments in nanostructured catalysts address this challenge reporting remarkable performances in shape and morphology dependent catalysis by metals on nano scale in energy and environmental applications. In this review, most recent advances in synthesis of heterogeneous nanomaterials, surface characterization and catalytic performances for hydrogenation and oxidation for biorenewables with plausible mechanism have been discussed. The perspectives obtained from this review paper will provide insights into rational design of active, selective and stable catalytic materials for sustainable production of value‐added chemicals from biomass resources.
Superdiversity and City Branding: Rotterdam in Perspective
Authors: Belabas Warda , Eshuis Jasper 
Published: November 2018

AbstractAs many other cities around the world, Rotterdam has been investing in improving its image to stimulate urban development and to attract visitors, residents and investors. In particular, during the last 15 years the municipality of Rotterdam has intensified its attempts to develop a ‘brand’ that fits the ‘new Rotterdam’, which was gradually rebuilt after destructive bombardments during the Second World War (Riezebos 2014). In 2014 Rotterdam was ranked 8th by ‘Rough Guide’ in the list of ‘Top 10 Cities to See’, whereas the ‘New York Times’ listed Rotterdam in the top 10 of 52 Places to Go. These rankings demonstrate Rotterdam’s success in repositioning itself, using the physical interior of the city as a key element in its branding strategy.
The Second and Third Generation in Rotterdam: Increasing Diversity Within Diversity
Authors: Crul Maurice , Lelie Frans , Keskiner Elif 
Published: November 2018

AbstractThe children of immigrants, the second and the third generations, are inheriting the city of Rotterdam. They make up about two thirds of the Rotterdam population of the future. As a result, what is the future of Rotterdam? We will show that the most prominent trend within the second generation is polarization. The group that was able to move up into the lower and upper middle-class is equally large – or for some ethnic groups even larger – as the group in the working class. An intersectional approach in which generation, socio-economic position and ethnicity all play a role seems to be much more appropriate than an approach looking at ethnic groups alone. It is exactly the increased diversity within ethnic groups that underscores the concept of superdiversity for cities like Rotterdam.
Rotterdam as a Case of Complexity Reduction: Migration from Central and Eastern European Countries
Authors: Snel Erik , van Ostaijen Mark , ‘t Hart Margrietha 
Published: November 2018

AbstractVarious authors have described the Netherlands as a ‘reluctant country of immigration’. Although the Netherlands was de facto an immigration country, until recently it seemed unwilling to admit it (Cornelius et al. 2004; Muus 2004; Van Meeteren et al. 2013). Similarly, with 174 different nationalities in the city, Rotterdam is characterised by ‘superdiversity’ (Vertovec 2007). But unlike cities such as London or Amsterdam who celebrate their diverse populations, Rotterdam is rather reluctant to do so. Rotterdam local politics and local policies seldom welcome ethnic and cultural diversity in the city. They rather underline the problems related to the presence of migrants and their families, particularly when they live concentrated in certain Rotterdam districts. This reluctance is also apparent in the reaction of Rotterdam authorities to the arrival and settlement of new migrants from Central and Eastern Europe in the aftermath of the EU-enlargement in 2004, the central topic of this chapter. Although statistics about the size of Central and Eastern European (further CEE) migrants and how many families actually live in the city are contested, Rotterdam authorities estimated their numbers to be up to 50,000 (Municipality Rotterdam 2015).
Microdialysis in Postoperative Monitoring of Gastrointestinal Organ Viability: A Systematic Review
Authors: Sabroe Jonas Emil , Qvist Niels , Ellebæk Mark Bremholm 
Published: November 2018

AbstractBackgroundMicrodialysis is a technique for continuous measurement of extracellular substances. It may be used to monitor tissue viability. The clinical implications of using microdialysis as a tool in gastrointestinal surgery have yet to be defined. The aim of the present study was to evaluate the clinical significance of microdialysis with special attention to different markers measured to predict the clinical outcome of surgical patients.MethodsEmbase, MEDLINE, and the Cochrane Library were searched systematically for human studies written in English. Study selection, data extraction, and quality assessment were performed independently by two authors. We included studies in which the microdialysis technique was used for postoperative monitoring of patients undergoing gastrointestinal surgery. To be eligible, studies had to compare patients with and without postoperative complications.ResultsTwenty‐six studies were included in this review. MINORS score ranged from 3 to 12 (median 10.5). Most studies showed that levels of biomarkers obtained by microdialysis correlated with the postoperative clinical course. Lactate, pyruvate, glucose, and glycerol were the most frequently measured biomarkers. Several studies found that changes in biomarkers in complicated patients preceded symptoms of complications and/or changes in conventional paraclinical methods of postoperative monitoring.ConclusionsStudies show that microdialysis may have the potential to become a tool in postoperative surveillance of surgical patients. Larger randomized studies are needed to define the clinical implications of microdialysis.
Ecological momentary assessment of emotional awareness: Preliminary evaluation of psychometric properties

Published: November 2018

AbstractThe Levels of Emotional Awareness Scale (LEAS) is a well-validated performance measure of trait emotional awareness (EA), which is associated with psychological and physical problems. EA is, however, expected to vary over time and we aimed to adapt the LEAS to permit the measurement of EA in daily life as a function of momentary state. Twenty-five students completed 12 ecological momentary assessments (EMAs) of EA across 2 days. The correlation between the mean EMAs of EA and trait EA, and the change over time in EA, was also examined. Findings revealed a significant positive correlation between state and trait EA. The within-person reliability was substantial, suggesting that EMAs can reliably assess EA over time across individuals. Importantly, latent state-trait analysis showed that about 50% of EA variability was due to state variance whereas only 2% of EA variability was due to trait variance. Preliminary psychometric properties suggest that the developed method allows for the measurement of EA in daily life and supports the claim that EA can be measured using both hypothetical (as in the LEAS) and real-life (using EMAs) scenarios.

Published: November 2018

AbstractBackground:Punitive parenting and stressful life events are associated with obsessive-compulsive symptoms (OCS). However, the lack of longitudinal, genetically-informative studies means it remains unclear whether these factors represent environmentally-mediated risks for the development of OCS.Methods:Twins and siblings from the Genesis1219 study completed self-report questionnaires two years apart (Time 1: N = 2616, mean age = 15.0; Time 2: N = 1579, mean age = 17.0 years) assessing OCS, maternal and paternal punitive parenting, and dependent stressful life events. Multiple regression models tested cross-sectional and longitudinal associations between the putative environmental risk factors and obsessive-compulsive symptoms using: (a) individual scores; and (b) monozygotic twin difference scores. The aetiologies of significant phenotypic associations between putative risk factors and OCS were further examined using multivariate genetic models.Results:At a phenotypic level, maternal and paternal punitive parenting and stressful life events were all associated with OCS both cross-sectionally and longitudinally. However, only stressful life events predicted the subsequent development of OCS, after controlling for earlier symptoms. Genetic models indicated that the association between life events and change in OCS symptoms was due to both genetic (48%) and environmental (52%) influences. Overall, life events associated with change in OCS accounted for 1.2% of variation in OCS at Time 2.Conclusions:Stressful life events, but not punitive parenting, predict OCS change during adolescence at a phenotypic level. This association exists above and beyond genetic confounding, consistent with the hypothesis that stressful life events play a causal role in the development of obsessive-compulsive symptoms.
Securing VoIP: encrypting today's digital telephony systems
Authors: Claxson Nick 
Published: November 2018

Cyber security is a topic on every organisation's radar. It was only very recently that we heard about the catastrophic Dixons Carphone data breach, which involved 5.9 million card payments and the personal data records of 1.9 million people. 1 And who can forget the infamous TalkTalk hack from 2015, in which the personal details of 157,000 customers were compromised? 2 As a result of this breach, the company was hit with a record £400,000 fine. One persistent cyber security myth is that cyber attacks only ever involve attackers exploiting system vulnerabilities and stealing personal data. In fact, telecoms systems are equally susceptible to coming under attack. And as telephony is the beating heart of any business, it is essential that all businesses employ secure encryption as a part of their telecoms set-up. And there are three elements to this – awareness, education and action, argues Nick Claxson of Comtec.
Electrocoalescence of a pair of conducting drops in an insulating oil

Published: November 2018

The effect of an electric field on the coalescence of two water drops suspended in an insulating oil is investigated. We report four new results. (i) The cone angle for the non-coalescence of drops can be significantly smaller (as small as $19^{\circ }$) than the value of $30.8^{\circ }$ reported by Bird et al. (Phys. Rev. Lett., vol. 103 (16), 2009, 164502). (ii) A surprising observation of the dependence of the mode of coalescence/non-coalescence on the type of insulating oil is seen. A cone–cone mode for silicone oil is observed as against cone–dimple mode for castor oil. (iii) The critical capillary number for non-coalescence decreases with increase in the conductivity of the droplet phase. (iv) Systematic experiments prove that the apparent bridge during non-coalescence is indeed transitory and not permanent, as reported elsewhere. Theoretical calculations using analytical theory and the boundary integral method explain the formation of the cone–dimple mode as well as the transitory bridge length. The numerical calculation and thereby the physical mechanism to explain the occurrence of very small non-coalescence angles as well as the dependence of the phenomenon on the conductivity of the insulating oil and the water droplets remain unexplained.
Oil to cash in Somaliland: a debate whose time has come
Authors: Pegg Scott 
Published: November 2018

AbstractSomaliland might start producing oil in 2019. Yet, it has done little to prepare for the arrival of oil revenues which could exceed its current annual budget. Although Somaliland has been largely peaceful for two decades and recently inaugurated its fifth president after holding a democratic election, it remains entirely unrecognised. Oil revenues could positively transform Somaliland's fragile political economy, but they also place it at significant risk for a political resource curse that could threaten its democracy, peace and political institutions. Oil to cash or the direct distribution of oil revenues to citizens has been posited as a solution to the political resource curse. Somaliland has many of the elements necessary to make oil to cash work in place. Several factors combine to make Somaliland both potentially receptive to oil to cash and uniquely positioned to benefit from it. Interviews with political elites demonstrate receptiveness to the idea. Sample revenue calculations from other African oil producers highlight just how such a system could work to benefit Somaliland.

Published: November 2018

SummaryTo achieve the challenging goals of minimizing loss of species and achieving sustainable use of biodiversity, conservation prioritization merits urgent research attention. The present study identifies the priority of conservation for the medicinal flora of the Jammu and Kashmir (J&K) region, a Himalayan biodiversity hotspot. A total of 881 medicinal plant species were scored based on key ecological (endemism, threat status) and socioeconomic (use value, mode of harvesting) criteria, and 50 of these are prioritized for conservation; most of these are narrow endemics. Worryingly, all of the 50 prioritized species are currently recognized under different International Union for Conservation of Nature and Natural Resources threat categories, are highly prized for their use in traditional medicine in the region and are precious sustainable bioresources for the herbal industry. Most of these prioritized species are being harvested illegally. This integrated ecological and socioeconomic study has immediate implications for evidence-based and target-orientated conservation policy and practice in this Himalayan region.
Global spatial assessment of Aedes aegypti and Culex quinquefasciatus: a scenario of Zika virus exposure

Published: November 2018

AbstractZika virus (ZIKV) is an arbovirus transmitted mainly by Aedes aegypti mosquitoes. Recent scientific evidence on Culex quinquefasciatus has suggested its potential as a vector for ZIKV, which may change the current risk zones. We aimed to quantify the world population potentially exposed to ZIKV in a spatially explicit way, considering the primary vector (A. aegypti) and the potential vector (C. quinquefasciatus). Our model combined species distribution modelling of mosquito species with spatially explicit human population data to estimate ZIKV exposure risk. We estimated the potential global distribution of C. quinquefasciatus and estimated its potential interaction zones with A. aegypti. Then we evaluated the risk zones for ZIKV considering both vectors. Finally, we quantified and compared the people under risk associated with each vector by risk level, country and continent. We found that C. quinquefasciatus had a more temperate distribution until 42° in both hemispheres, while the risk involving A. aegypti is concentrated mainly in tropical latitudes until 35° in both hemispheres. Globally, 4.2 billion people are under risk associated with ZIKV. Around 2.6 billon people are under very high risk associated with C. quinquefasciatus and 1 billion people associated with A. aegypti. Several countries could be exposed to ZIKV, which emphasises the need to clarify the competence of C. quinquefasciatus as a potential vector as soon as possible. The models presented here represent a tool for risk management, public health planning, mosquito control and preventive actions, especially to focus efforts on the most affected areas.

Published: November 2018

AbstractObjectiveTo develop an index to assess the nutritional quality of household food purchases based on food expenditures only.DesignA database of monthly food purchases of a convenience sample of low-income households was used to develop the Healthy Purchase Index (HPI). The HPI is the sum of two sub-scores based on expenditure shares of food categories in total household food expenditure: the purchase diversity sub-score and the purchase quality sub-score. The first was adapted from an existing diversity score. The second integrated those food categories identified as the best predictors of the nutritional quality of purchases based on associations between expenditure shares of food categories and two nutritional quality indicators: the mean adequacy ratio (MAR) and the mean excess ratio (MER). Correlation between the HPI and a score assessing adherence to French dietary guidelines (PNNS-GSmod) was performed as a first validation.Setting/ParticpantsFood purchases of 112 households from deprived neighbourhoods of Marseille (France), participating in the Opticourses and Jassur projects (2012–2015).ResultsThe purchase diversity sub-score reflects the presence in food purchases of five food categories: fruits, vegetables, starches, dairy products, and meat, fish & eggs. The purchase quality sub-score is based on expenditure shares for fruit & vegetables, added fats & seasonings, sweet snacks, cheese, sugary drinks, refined grains and fish, as these were identified as predictors of the nutritional quality of purchases. The HPI was positively associated with the PNNS-GSmod(rs=0·378;P<0·001).ConclusionsThe HPI helps assess the healthiness of household food purchases.

ABSTRACTThe lower Mississippian Ballagan Formation of northern Britain is one of only two successions worldwide to yield the earliest known tetrapods with terrestrial capability following the end-Devonian mass extinction event. Studies of the sedimentary environments and habitats in which these beasts lived have been an integral part of a major research project into how, why and under what circumstances this profound step in the evolution of life on Earth occurred. Here, a new palaeogeographic map is constructed from outcrop data integrated with new and archived borehole material. The map shows the extent of a very low-relief coastal wetland developed along the tropical southern continental margin of Laurussia. Coastal floodplains in the Midland Valley and Tweed basins were separated from the marginal marine seaway of the Northumberland–Solway Basin to the south by an archipelago of more elevated areas. A complex mosaic of sedimentary environments was juxtaposed, and included fresh and brackish to saline and hypersaline lakes, a diverse suite of floodplain palaeosols and a persistent fluvial system in the east of the region. The strongly seasonal climate led to the formation of evaporite deposits alternating with flooding events, both meteoric and marine. Storm surges drove marine floods from the SW into both the western Midland Valley and Northumberland–Solway Basin; marine water also flooded into the Tweed Basin and Tayside in the east. The Ballagan Formation is a rare example in the geological record of a tropical, seasonal coastal wetland that contains abundant, small-scale evaporite deposits. The diverse sedimentary environments and palaeosol types indicate a network of different terrestrial and aquatic habitats in which the tetrapods lived.
The Oxygen Ion Circulation in The Outer Terrestrial Magnetosphere and Its Dependence on Geomagnetic Activity
Authors: Slapak R. , Nilsson H. 
Published: November 2018

AbstractWe have quantified the O+ transports in the plasma sheet and lobes (−20 < XGSM<−10RE) and their dependencies on geomagnetic activity, Kp, using Cluster data. We found that they have similar behavior as the polar region O+ outflow as well as the O+ fluxes in the plasma mantle and high‐latitude dayside magnetosheath, in their response to geomagnetic activity. The sum of the total O+ fluxes in the lobes, plasma sheet, plasma mantle, and high‐latitude magnetosheath equals the O+ outflow above the polar regions for any geomagnetic condition. It can be argued that there are no hidden O+ populations for Cluster, in the sense that there are no significant amounts of O+ with energies outside the energy range of the ion spectrometer, Composition Distribution Function, and/or below the spacecraft potential. Therefore, we have obtained a complete picture of the O+ circulation (and escape) in the outer magnetosphere and its dependence on geomagnetic activity.
