In the context of sustainable utilisation of valuable but neglected plant resources, a multifaceted study is presented herein for Greek native genotypes of elderberry (Sambucus nigra L., Caprifoliaceae), a species with an appreciated pharmaceutical and nutritional value. At the first phase, fresh plant materials (leaves, softwood cuttings) were collected from nine geographically separated genotypes originating from wild-growing Greek native germplasm of S. nigra. The leaf samples were genetically authenticated using DNA barcoding (ITS2). The next phase included the development of an asexual propagation protocol via cuttings which included screening of the collected genotypes in terms of propagation success, and further experimentation over a two-year period on a prioritised genotype. The propagation results highlighted the importance of external application of indole-3-butyric acid (IBA) rooting hormone at levels of 2000–4000 ppm, which consistently presented high rooting rates (100%) of summer softwood, leafy cuttings of apical or sub-apical type. At the same time, rooting quality in terms of root number and length as well as early plant growth after rooting, were improved by external hormone application resulting in high rates of plant survival. This study reports first-time data on multifaceted assessment of Greek native S. nigra genotypes on molecular authentication and asexual propagation, thus ultimately setting the basis for domestication and sustainable utilization of this species.

AbstractThe need for qualitative research of deservingness perception is strongly emphasised in the literature. This article studies the perception of deservingness for a "Family 500 +"—cash benefit in Poland. For the first time, data from online forums was used in the studies of deservingness and welfare attitudes. It allowed to avoid numerous limitations associated with social surveys. The qualitative analysis showed how participants of Internet debates perceive the criteria of deservingness: control, attitude, reciprocity, identity, need, and what are the relations between the criteria. The impurity of all deservingness criteria was indicated and a new criterion “adequacy” was proposed. Moreover due to the fact that the study concerned a concrete, non-abstract family cash benefit addressed the relationship between the perceived deservingness of children and their parents was pointed out. The vast majority of posts on Internet forums referred to deservingness of parents, not children. This is particularly evident in relation to the criteria of control and reciprocity. Presenting the hypothesis of jealousy and scapegoat strategy, the article also shows the direction of future research on deservingness.

We report on longitudinal changes in the system of intensification in an innovative corpus that spans five decades of dialectal speech. Our analyses allow us — for the first time in a British context — to trace the quantitative development in the variable across four generations. Longitudinal analysis across real and apparent time determines the effect of extralinguistic and intralinguistic variables on intensification in Tyneside and tests to what extent real time data corroborates trends reported from previous apparent time analyses. Long-term competition within the variable manifests itself in distinctive developmental trajectories: expansion — both proportionally within the variable as well as across adjectival categories — tends to follow one of three types of patterns, exemplified, respectively, by really, so and dead. Variant retraction, however, follows only one schema. Importantly, numerical decline in the system does not necessarily go hand in hand with a reduction in breadth of application.

Abstract. Radium-228 (228Ra), an almost conservative trace isotope in the ocean, supplied from the continental shelves and removed by a known radioactive decay (T1∕2 = 5. 75 years), can be used as a proxy to constrain shelf fluxes of other trace elements, such as nutrients, iron, or rare earth elements. In this study, we perform inverse modeling of a global 228Ra dataset (including GEOSECS, TTO and GEOTRACES programs, and, for the first time, data from the Arctic and around the Kerguelen Islands) to compute the total 228Ra fluxes toward the ocean, using the ocean circulation obtained from the NEMO 3.6 model with a 2° resolution. We optimized the inverse calculation (source regions, cost function) and find a global estimate of the 228Ra fluxes of 8.01–8. 49 × 1023 atoms yr−1, more precise and around 20 % lower than previous estimates. The largest fluxes are in the western North Atlantic, the western Pacific and the Indian Ocean, with roughly two-thirds in the Indo-Pacific Basin. An estimate in the Arctic Ocean is provided for the first time (0.43–0.50  ×  1023 atoms yr−1). Local misfits between model and data in the Arctic, the Gulf Stream and the Kuroshio regions could result from flaws of the ocean circulation in these regions (resolution, atmospheric forcing). As radium is enriched in groundwater, a large part of the 228Ra shelf sources comes from submarine groundwater discharge (SGD), a major but poorly known pathway for terrestrial mineral elements, including nutrients, to the ocean. In contrast to the 228Ra budget, the global estimate of SGD is rather unconstrained, between 1.3 and 14. 7 × 1013 m3 yr−1, due to high uncertainties on the other sources of 228Ra, especially diffusion from continental shelf sediments. Better precision on SGD cannot be reached by inverse modeling until a proper way to separate the contributions of SGD and diffusive release from sediments at a global scale is found.

PurposeA well-documented pattern in the literature concerns the outperformance of small-cap stocks relative to their larger-cap counterparts. This paper aims to address the “small-cap versus large-cap” issue using for the first time data from the exchange traded funds (ETFs) industry.Design/methodology/approachSeveral raw return and risk-adjusted return metrics are estimated over the period 2012-2016.FindingsResults are partially supportive of the “size effect”. In particular, small-cap ETFs outperform large-cap ETFs in overall raw return terms even though they fail the risk test. However, outperformance is not consistent on an annual basis. When risk-adjusted returns are taken into consideration, small-cap ETFs are inferior to their large-cap counterparts.Research limitations/implicationsThis research only covers the ETF market in the USA. However, given the tremendous growth of ETF markets worldwide, a similar examination of the “small vs large capitalization” issue could be conducted with data from other developed ETF markets in Europe and Asia. In such a case, useful comparisons could be made, so that we could conclude whether the findings of the current study are unique and US-specific or whether they could be generalized across the several international ETF markets.Practical implicationsA possible generalization of the findings would entail that profitable investment strategies could be based on the different performance and risk characteristics of small- and large-cap ETFs.Originality/valueThis is the first study to examine the performance of ETFs investing in large-cap stock indicesvis-à-visthe performance of ETFs tracking indices comprised of small-cap stocks.

ABSTRACTThe literature on aid allocation shows that many factors influence donors’ decision to provide aid. However, our knowledge about foreign aid allocation is based on traditional foreign aid, from developed to developing countries, and many assumptions of these theories do not hold when applied to southern donors. This article argues that south-south development cooperation (SSDC) can be explained by the strength of development cooperation’s domestic allies and foes. Specifically, it identifies civil society organizations as allies of SSDC and nationalist groups as opponents of SSDC. By using for the first time data on SSDC activities in Latin America, this article shows the predictive strength of a liberal domestic politics approach in comparison to the predictive power of alternative explanations. The results speak to scholars of both traditional foreign aid and south-south development cooperation in highlighting the limits of traditional theories of foreign aid motivations.

The Society for Acute Medicine’s Benchmarking Audit (SAMBA) was undertaken for the 5th time in June 2016. For the first time, data on telephone triage calls prior to admission to Acute Medical Units were collected: 1238 patients were referred from Emergency Departments, 925 from General Practitioners (GPs), 52 from clinics and 147 from other sources. Calls from Emergency Departments rarely resulted in admission avoidance. Calls from Primary Care resulted in avoidance of an admission in 115 (12%) patients; the percentage of avoided admissions was highest if the call was taken by a Consultant. Consultant triage might result in admission avoidance but the impact of local context on the effectiveness is not clear.

Two taxa of Amomum (Zingiberaceae), Amomum erythranthum and Amomum ampliflorum, from Putao, Kachin State of Northern Myanmar are described and illustrated as new to science. Amomum erythranthum is morphologically similar to A. subulatum and A. nimkeyense in having similar yellow flowers, but can be distinguished by its reddish floral tube, red anther connective, red and pubescent fruit. Amomum ampliflorum is similar to A. maximum, A. dealbatum and A. odontocarpum in white flower, but differs in its longer inflorescence and much larger flower. Two species, Amomum pauciflorum and Wurfbainia microcarpum are recorded for the flora of Myanmar for the first time. Data on ecology, phenology, distribution, conservation status, similarities to the related taxa, as well as colour photographs and line drawings of the type, and voucher specimens are provided for all reported taxa.

AbstractBased on more than 1100 samples of Emys orbicularis and E. trinacris, data on mtDNA diversity and distribution of haplotypes are provided, including for the first time data for Armenia, Georgia, Iran, and the Volga, Ural and Turgay River Basins of Russia and Kazakhstan. Eight mitochondrial lineages comprising 51 individual haplotypes occur in E. orbicularis, a ninth lineage with five haplotypes corresponds to E. trinacris. A high diversity of distinct mtDNA lineages and haplotypes occurs in the south, in the regions where putative glacial refuges were located. More northerly parts of Europe and adjacent Asia, which were recolonized by E. orbicularis in the Holocene, display distinctly less variation; most refuges did not contribute to northern recolonizations. Also in certain southern European lineages a decrease of haplotype diversity is observed with increasing latitude, suggestive of Holocene range expansions on a smaller scale.
