Evaluating the effect of instruction and practice schedule on the acquisition of ECG interpretation skills
Authors: Monteiro Sandra , Melvin Lindsay , Manolakos Joshua , Patel Ameen , Norman Geoffrey 
Published: July 2017

Introduction Evidence of the benefit of distributed instruction and interleaved practice comes from studies using simple materials (e. g. word pairs). Furthermore, there is currently no evidence of the combined impact of these strategies in undergraduate medical education. The present study evaluated the impact of varying both instruction and practice schedules for the acquisition of ECG interpretation skills.
Methods We conducted a 2 × 2 factorial study with two levels of instruction (massed and distributed) and two levels of practice (interleaved and blocked). A three-module introductory course in ECG interpretation was delivered to 80 first year medical undergraduate students. Students were assigned to one of four Instruction-Practice conditions: Massed-Interleaved, Massed-Blocked, Distributed-Interleaved and Distributed-Blocked. Learning was evaluated by a multiple choice quiz at the end of each module and a final multiple choice quiz at the end of the course.
Results End of module mean scores showed that distributed instruction was consistently superior to massed instruction (52% vs 42%, p < 0.01). However, there was no effect of practice and no interaction between teaching and practice methods. The delayed final test scores revealed an advantage for blocked over mixed practice (34% vs 24%, p < 0.05) and distributed over massed instruction (34% vs 24%, p < 0.05).
Discussion These results suggest that these popular strategies may have varying effects with complex learning materials.
The role of appearance schematicity in the internalization of media appearance ideals: A panel study of preadolescents
Authors: Rousseau Ann , Gamble Hilary , Eggermont Steven 
Published: July 2017

ABSTRACTIndividuals who are more strongly invested in their appearance, appearance schematics, have a tendency to engage in appearance‐related comparison. Appearance schematicity consists of two components. The self‐evaluative component concerns the degree to which appearance is central to self‐worth, referred to as dysfunctional appearance beliefs. Motivational salience refers to the engagement in behaviors designed to enhance appearance, such as body surveillance. Based on a three‐wave panel survey of 973 Flemish preadolescents (Mage = 11.15, SD = 1.13) we found that the motivational and self‐evaluative components had a different impact on media internalization. For preadolescents who engaged in more body surveillance, watching television resulted in more media internalization. For preadolescents who had fewer dysfunctional appearance beliefs, watching television resulted in more media internalization. These findings suggest that appearance schematicity is an important susceptibility variable in the relationship between TV‐exposure and media internalization, and emphasize the importance of investigating individual dispositions beyond gender differences.
Well-posedness and exponential equilibration of a volume-surface reaction–diffusion system with nonlinear boundary coupling
Authors: Fellner Klemens , Latos Evangelos , Tang Bao Quoc 
Published: July 2017

We consider a model system consisting of two reaction–diffusion equations, where one species diffuses in a volume while the other species diffuses on the surface which surrounds the volume. The two equations are coupled via a nonlinear reversible Robin-type boundary condition for the volume species and a matching reversible source term for the boundary species. As a consequence of the coupling, the total mass of the two species is conserved. The considered system is motivated for instance by models for asymmetric stem cell division.
Firstly we prove the existence of a unique weak solution via an iterative method of converging upper and lower solutions to overcome the difficulties of the nonlinear boundary terms. Secondly, our main result shows explicit exponential convergence to equilibrium via an entropy method after deriving a suitable entropy entropy-dissipation estimate for the considered nonlinear volume-surface reaction–diffusion system.
Twenty Years Preserving Data
Authors: Richards Julian D. 
Published: July 2017

ABSTRACTIn 2016 the Archaeology Data Service (ADS) was 20 years old. Since its birth the ADS has had to respond to rapid changes in technology, as well as major cultural and organizational changes in the external operating environment, from which a sustainable business model for digital preservation has emerged. This article will take a retrospective look at challenges that have been faced and will review current and future priorities for those seeking to establish digital repositories. Digital preservation and open access to research data are now much higher up the agenda of funding bodies, but there is still lack of agreement on what constitutes a core digital archive from a fieldwork project. The paper will review what the significant properties of an archaeological archive are, and how reuse can be supported, linking data and publications. It will consider the challenge of dealing with the gray literature and of avoiding creating further data silos, featuring new initiatives to provide interoperability between digital repositories. It will review the role of data and metadata standards, and consider how the profession needs to address its responsibilities over the next 20 years.

Introduction: Attempts to quit smoking have increased in recent years, but the patterns of variations over time are unknown. We aimed at describing time- and sex-related changes in a population of 2,231 subjects who adhered to a smoking-cessation programme lasting 13 years in Italy.Methods: We measured baseline expired carbon monoxide (expired-CO), Fagerstrom nicotine dependence, Q-MAT test, Zung depression and anxiety scale, Hospital anxiety and depression scale (HADS).Results: Study population included 1,278 men and 953 women who smoked a median of 25 (interquartile range, IQR: 20–32) and 20 (IQR: 20–30) cigarettes/day, respectively (p < 0.001). The proportion of female smokers increased from 37.5% in 2001–2003 to 46.9% in 2010–2013 (p = 0.003). There was a significant time-related reduction of median daily cigarette consumption, with a more noticeable decrease in men. Median expired-CO (parts per million (ppm)) increased only in women, from 18 (IQR: 14–23) in 2001–03 to 20 (IQR: 14–28) in 2010–13 (p = 0.001), whereas Fagerstrom test for nicotine dependence did not vary. Differences in psychological characteristics in the last 3 years showed that women were more clinically depressed than men (16.6% versus 7.6%, p < 0.001).Conclusions: Despite a decrease in the number of daily cigarettes with time, expired-CO tends to increase in women, who are also more clinically depressed and anxious than men. A personalised approach to specific subgroups of smokers, with special emphasis on a psychological support for women, seems appropriate.
Cultural Diversity and International Order
Authors: Reus-Smit Christian 
Published: July 2017

AbstractThe modern international order faces profound challenges. Power is shifting to non-Western states and diffusing to non-state actors, including transnational insurgents. This is more than a power transition: it also about culture. Western states now share the stage with powers such as China who bring their own cultural values, practices, and histories, and new forms of transnational violence are justified in the name of religious identity and belief. Some see this as a fundamental threat to modern international order, an order created by and for the West. Others see the “liberal” order as uniquely able to accommodate states and peoples of diverse cultures. How well equipped is IR to contribute to these debates? I review four recent works on the future of the modern international order, asking what conceptual, theoretical, and empirical resources they offer for understanding the relationship between cultural diversity and international order. This literature suffers from four limitations: culture is essentialized or bracketed; institutions are seen as either simple expressions of cultural values or structures that neutralize culture, with their recognition function ignored; the structural power of international orders—how they produce political and cultural subjectivities—is underappreciated; and international orders are conceived too narrowly as orders of sovereign states. To overcome these limitations, I advance a new perspective on cultural diversity and international order. International orders evolve in heterogeneous cultural contexts, and the governance of diversity is a key imperative of order building. In response, international orders developdiversity regimes: institutional norms and practices that define legitimate units of political authority, authorize certain forms of cultural difference, and relate the two. These regimes are essential to the legitimacy of international orders, but face two interrelated pressures for change: shifts in underlying material capabilities, and new claims for cultural recognition, often rooted in grievances against past or prevailing forms of recognition.
Analysis of Anti-Domestic Violence Policy Implementation in Georgia Using Contextual Interaction Theory (CIT)
Authors: JAVAKHISHVILI NINO , JIBLADZE GVANTSA 
Published: July 2017

AbstractThis study examines the development of anti-domestic-violence policy implementation in an emerging democracy, the country of Georgia. We applied a public policy framework – Contextual Interaction Theory (CIT) – which enabled us to thoroughly examine factors contributing to drawbacks in anti-domestic-violence policy implementation. The CIT framework was enriched by expanding it to the scale of the national anti-domestic-violence policy and placing greater emphasis on the victim. The qualitative analysis of in-depth interviews and media reveals that public policy implementers lack motivation, information and power to be able to really implement the anti-domestic-violence policy. The CIT analysis of domestic violence (DV) policies demonstrates that DV problems are further exacerbated by the contextual factors of societal attitudes in terms of gender inequality and social acceptance of DV, which creates unfavorable context for the realisation of the anti-DV policy. In such circumstances, according to the CIT, only symbolic realisation of a policy takes place. The use of CIT as a tool for the implementation of a policy will provide substantial input into its realisation. Based on this theory, it is crucial to increase information, motivation and power of implementers, as well as change the context for the anti-DV policy to be actually implemented.
On-line processing of English which-questions by children and adults: a visual world paradigm study
Authors: CONTEMORI CARLA , CARLSON MATTHEW , MARINIS THEODOROS 
Published: July 2017

AbstractPrevious research has shown that children demonstrate similar sentence processing reflexes to those observed in adults, but they have difficulties revising an erroneous initial interpretation when they process garden-path sentences, passives, and wh-questions. We used the visual-world paradigm to examine children's use of syntactic and non-syntactic information to resolve syntactic ambiguity by extending our understanding of number features as a cue for interpretation to which-subject and which-object questions. We compared children's and adults’ eye-movements to understand how this information shapes children's commitment to and revision of possible interpretations of these questions. The results showed that English-speaking adults and children both exhibit an initial preference to interpret an object-which question as a subject question. While adults quickly override this preference, children take significantly longer, showing an overall processing difficulty for object questions. Crucially, their recovery from an initially erroneous interpretation is speeded when disambiguating number agreement features are present.

Published: July 2017

SummaryNetworks of protected areas (PAs) where human activities are allowed at different degrees are fundamental to ensure the long-term conservation of biological diversity and ecological processes. However, studies aimed at assessing their effectiveness, focusing on several species simultaneously are scarce. We assessed the effectiveness of the system of protected areas (PAs) of Lombardy, Northern Italy, in conserving bird populations by comparing the changes from 1992 to 2013 in the occurrence of 54 breeding bird species censused in areas classified in different protection categories, namely Nature Reserves (NRs), areas designed predominantly for the protection of nature; Regional Parks (RPs), naturally valuable areas where human activities, including intensive agriculture, are allowed; and non-protected areas (NPAs). Overall, occurrence of common birds increased in Lombardy in the last 20 years and farmland and long-distance migrants (LDMs), which suffered sharp declines at a continental scale, showed stable and increasing trends, respectively. These trends were, however, the balance between those of species whose occurrence markedly increased, and those of species that dramatically declined. Species occurred more often in PAs than in NPAs, while temporal trends in occurrence were significantly more positive in RPs than in both NRs and NPAs. Hence, PAs seemed effective in preserving common bird communities. Occurrence of woodland and short-distance migrant species was higher in PAs than in NPAs, while occurrence of farmland species and LDMs was similar in all protection categories. PAs of Lombardy appear therefore effective only in protecting some categories of birds. Farmland and LDM birds would benefit more from ecologically sustainable land-use policies aiming at improving agro-ecosystem biodiversity than from protected areas.

AbstractObjectiveTo investigate the effectiveness of a culturally adapted lifestyle intervention for changing dietary intake, particularly energy, fat and fibre intakes, in the intervention group (IG) compared with the control group (CG).DesignRandomised controlled trial.SettingIG (n 50) and CG (n 46). The IG was offered seven group sessions, including one cooking class, over a period of 4 months. The participants filled out 4 d food diaries at the start, mid and end of the study.SubjectsIraqi-born residents of Malmö, Sweden, at increased risk for developing diabetes.ResultsAt baseline, participants’ fat intake was high (40 % of total energy intake (E%)). The predefined study goals of obtaining <30 E% from fat and ≥15 g fibre/4184 kJ (1000 kcal) were met by very few individuals. In the IG v. the CG, the proportion of individuals obtaining <40 E% from fat (48·4 v. 34·6 %, P=0·65), <10 E% from saturated fat (32·3 v. 11·5 %, P=0·14) and ≥10 g fibre/4184 kJ (45·2 v. 26·9 %, P=0·46) appeared to be higher at the last visit, although the differences were statistically non-significant. A trend towards decreased mean daily intakes of total energy (P=0·03), carbohydrate (P=0·06), sucrose (P=0·02) and fat (P=0·02) was observed within the IG. Differences in changes over time between the groups did not reach statistical significance.ConclusionsAlthough no significant differences were observed in the two groups, our data indicate that this culturally adapted programme has the potential to modify dietary intake in Middle Eastern immigrants. The high fat intake in this group should be addressed.

AbstractObjectiveTo quantify associations of the dietary share of ultra-processed foods (UPF) with the overall diet quality of First Nations peoples.DesignA cross-sectional analysis of data from the First Nations Food, Nutrition and Environment Study, designed to contribute to knowledge gaps regarding the diet of First Nations peoples living on-reserve, south of the 60th parallel. A multistage sampling of communities was conducted. All foods from 24 h dietary recalls were categorized into NOVA categories and analyses were performed to evaluate the impact of UPF on diet quality.SettingWestern and Central Canada.SubjectsFirst Nations participants aged 19 years or older.ResultsThe sample consisted of 3700 participants. UPF contributed 53·9 % of energy. Compared with the non-UPF fraction of the diet, the UPF fraction had 3·5 times less vitamin A, 2·4 times less K, 2·2 times less protein, 2·3 times more free sugars and 1·8 times more Na. As the contribution of UPF to energy increased so did the overall intakes of energy, carbohydrate, free sugar, saturated fat, Na, Ca and vitamin C, and Na:K; while protein, fibre, K, Fe and vitamin A decreased. Diets of individuals who ate traditional First Nations food (e.g. wild plants and game animals) on the day of the recall were lower in UPF.ConclusionsUPF were prevalent in First Nations diets. Efforts to curb UPF consumption and increase intake of traditional First Nations foods and other fresh or minimally processed foods would improve diet quality and health in First Nations peoples.
Is colonialism history? The declining impact of colonial legacies on African institutional and economic development
Authors: MASELAND ROBBERT 
Published: July 2017

AbstractThis paper investigates the claim that colonial history has left an enduring imprint on Africa's institutional and economic development. The literature following Acemoglu, Johnson and Robinson (2001) and Sokoloff and Engerman (2000) maintains that different types of colonialism affected the institutional environment differently, and that path-dependence subsequently ensures that these institutional differences and their impact on economic performance are persistent over time. By tracing the impact of colonial institutions on contemporary institutions over time, I show that – in contrast to claims in this literature – the relevance of colonial legacies to institutional quality and to per capita income is rapidly disappearing in Africa. Differences in institutional quality or income are explained less and less by colonial legacy, while there is some evidence that precolonial social and geographical circumstances are becoming more important. I conclude that while colonialism has affected African institutional and economic development significantly, this impact is not persistent. Rather, the evidence suggests that colonialism has created a large but very temporary institutional shock, after which a long-run equilibrium is being restored.

Published: July 2017

Abstract
Nematode predation has important roles in determining bacterial community composition and dynamics, but the extent of the effects remains largely rudimentary, particularly in natural environment settings. Here, we investigated the complex microbial–microfaunal interactions in the rhizosphere of maize grown in red soils, which were derived from four long-term fertilization regimes. Root-free rhizosphere soil samples were separated into three aggregate fractions whereby the abundance and community composition were examined for nematode and total bacterial communities. A functional group of alkaline phosphomonoesterase (ALP) producing bacteria was included to test the hypothesis that nematode grazing may significantly affect specific bacteria-mediated ecological functions, that is, organic phosphate cycling in soil. Results of correlation analysis, structural equation modeling and interaction networks combined with laboratory microcosm experiments consistently indicated that bacterivorous nematodes enhanced bacterial diversity, and the abundance of bacterivores was positively correlated with bacterial biomass, including ALP-producing bacterial abundance. Significantly, such effects were more pronounced in large macroaggregates than in microaggregates. There was a positive correlation between the most dominant bacterivores Protorhabditis and the ALP-producing keystone ‘species’ Mesorhizobium. Taken together, these findings implicate important roles of nematodes in stimulating bacterial dynamics in a spatially dependent manner.
dRep: a tool for fast and accurate genomic comparisons that enables improved genome recovery from metagenomes through de-replication

Published: July 2017

Abstract
The number of microbial genomes sequenced each year is expanding rapidly, in part due to genome-resolved metagenomic studies that routinely recover hundreds of draft-quality genomes. Rapid algorithms have been developed to comprehensively compare large genome sets, but they are not accurate with draft-quality genomes. Here we present dRep, a program that reduces the computational time for pairwise genome comparisons by sequentially applying a fast, inaccurate estimation of genome distance, and a slow, accurate measure of average nucleotide identity. dRep achieves a 28 × increase in speed with perfect recall and precision when benchmarked against previously developed algorithms. We demonstrate the use of dRep for genome recovery from time-series datasets. Each metagenome was assembled separately, and dRep was used to identify groups of essentially identical genomes and select the best genome from each replicate set. This resulted in recovery of significantly more and higher-quality genomes compared to the set recovered using co-assembly.
Phaeoviruses discovered in kelp (Laminariales)

Published: July 2017

Abstract
Phaeoviruses are latent double-stranded DNA viruses that insert their genomes into those of their brown algal (Phaeophyceae) hosts. So far these viruses are known only from members of the Ectocarpales, which are small and short-lived macroalgae. Here we report molecular and morphological evidence for a new Phaeovirus cluster, referred to as sub-group C, infecting kelps (Laminariales) of the genera Laminaria and Saccharina, which are ecologically and commercially important seaweeds. Epifluorescence and TEM observations indicate that the Laminaria digitata Virus (LdigV), the type species of sub-group C, targets the host nucleus for its genome replication, followed by gradual degradation of the chloroplast and assembly of virions in the cytoplasm of both vegetative and reproductive cells. This study is the first to describe phaeoviruses in kelp. In the field, these viruses infected two thirds of their host populations; however, their biological impact remains unknown.
