In viticulture, grafting is used to propagate Phylloxera-susceptible European grapevines, thereby using resistant American rootstocks. Although scion–rootstock reciprocal signaling is essential for the formation of a proper vascular union and for coordinated growth, our knowledge of graft partner interactions is very limited. In order to elucidate the scale and the content of scion–rootstock metabolic interactions, we profiled the metabolome of eleven graft combination in leaves, stems, and phloem exudate from both above and below the graft union 5–6 months after grafting. We compared the metabolome of scions vs. rootstocks of homografts vs. heterografts and investigated the reciprocal effect of the rootstock on the scion metabolome. This approach revealed that (1) grafting has a minor impact on the metabolome of grafted grapevines when tissues and genotypes were compared, (2) heterografting affects rootstocks more than scions, (3) the presence of a heterologous grafting partner increases defense-related compounds in both scion and rootstocks in shorter and longer distances from the graft, and (4) leaves were revealed as the best tissue to search for grafting-related metabolic markers. These results will provide a valuable metabolomics resource for scion–rootstock interaction studies and will facilitate future efforts on the identification of metabolic markers for important agronomic traits in grafted grapevines.

Practical Implications

Purpose This paper aims to present a model of shareholders’ willingness to exert effort to reduce the likelihood of bank distress and the implications of the presence of contingent convertible (CoCo) bonds in the liabilities structure of a bank. Design/methodology/approach This study presents a basic model about the moral hazard surrounding shareholders willingness to exert effort that increases the likelihood of a bank’s success. This study uses a one-shot game and so do not capture the effects of repeated interactions. Findings Consistent with the existing literature, this study shows that the direction of the wealth transfer at the conversion of CoCo bonds determines their impact on shareholder risk-taking incentives. This study also finds that “anytime” CoCos (CoCo bonds trigger-able anytime at the discretion of managers) have a minor advantage over regular CoCo bonds, and that quality of capital requirements can reduce the risk-taking incentives of shareholders. Practical implications This study argues that shareholders can also use manager-specific CoCo bonds to reduce the riskiness of the bank activities. The issuance of such bonds can increase the resilience of individual banks and the whole banking system. Regulators can use restrictions on conversion rates and/or requirements on the quality of capital to address the impact of CoCo bonds issuance on risk-taking incentives. Originality/value To model the risk-taking incentives, authors generally modify the asset processes to introduce components that reflect asymmetric information between CoCo holders and shareholders and/or managers. This paper follows a simpler method similar to that of Holmström and Tirole (1998).

Abstract. As the most recent warm period in Earth's history with a sea-level stand higher than present, the Last Interglacial (LIG,  ∼  130 to 115 kyr BP) is often considered a prime example to study the impact of a warmer climate on the two polar ice sheets remaining today. Here we simulate the Last Interglacial climate, ice sheet, and sea-level evolution with the Earth system model of intermediate complexity LOVECLIM v.1.3, which includes dynamic and fully coupled components representing the atmosphere, the ocean and sea ice, the terrestrial biosphere, and the Greenland and Antarctic ice sheets. In this setup, sea-level evolution and climate–ice sheet interactions are modelled in a consistent framework.Surface mass balance change governed by changes in surface meltwater runoff is the dominant forcing for the Greenland ice sheet, which shows a peak sea-level contribution of 1.4 m at 123 kyr BP in the reference experiment. Our results indicate that ice sheet–climate feedbacks play an important role to amplify climate and sea-level changes in the Northern Hemisphere. The sensitivity of the Greenland ice sheet to surface temperature changes considerably increases when interactive albedo changes are considered. Southern Hemisphere polar and sub-polar ocean warming is limited throughout the Last Interglacial, and surface and sub-shelf melting exerts only a minor control on the Antarctic sea-level contribution with a peak of 4.4 m at 125 kyr BP. Retreat of the Antarctic ice sheet at the onset of the LIG is mainly forced by rising sea level and to a lesser extent by reduced ice shelf viscosity as the surface temperature increases. Global sea level shows a peak of 5.3 m at 124.5 kyr BP, which includes a minor contribution of 0.35 m from oceanic thermal expansion. Neither the individual contributions nor the total modelled sea-level stand show fast multi-millennial timescale variations as indicated by some reconstructions.

Objective: To study how divorce behavior in Denmark changed following a July 2013 reform that repealed mandatory separation periods for uncontested divorces, instead allowing for immediate administrative divorce.Background: Most countries have mandatory separation periods that couples undergo before they can divorce. Separation allows couples a grace-period, during which they may reconcile and stay together. Yet, the impact of separation periods on divorce risk remains understudied. Methods: Using monthly time series data on divorce rates from 2007-2018 (T=144), the research brief estimates the size and shape of the policy impact of the July 2013 reform. Using monthly administrative population data on all ever-married couples (N*T=40,431,848) the study further calculates the average characteristics of married couples in Denmark who would have remained together absent the reform.Results: After an initial spike in the divorce rate driven by couples divorcing earlier, the divorce rate settled at a 9.7 percent higher level compared to pre-reform. Couples who divorced because of the reform had been married for fewer years, were ethnic Danish, and had high school degree as highest educational level.Conclusion: Mandatory separation periods keep a minor, but substantial, share of potential divorcees together.

Abstract. Coarse sea salt particles are emitted ubiquitously from the oceans' surfaces by wave breaking and bubble bursting processes. These particles impact atmospheric chemistry by affecting condensation of gas-phase species and nucleation of new fine particles, particularly in regions with high air pollution. In this study, atmospheric particle concentrations are modeled for the North and Baltic Sea regions, Northwestern Europe, using the Community Multiscale Air Quality (CMAQ) modeling system and evaluated against European Monitoring and Evaluation Programme (EMEP) measurement data. As model extension, sea salt emissions are scaled by water salinity because of low salinity in large parts of the Baltic Sea and in certain river estuaries. The resulting improvement in predicted sea salt concentrations is assessed. The contribution of surf zone emissions is separately considered. Additionally, the impact of sea salt particles on atmospheric nitrate, ammonium and sulfate concentrations is evaluated. The comparisons show that sea salt concentrations are commonly overestimated at coastal stations and partly underestimated when going inland. The introduced salinity scaling improves predicted Baltic Sea sea salt concentrations considerably. Dates of measured peak concentrations are appropriately reproduced by the model. The impact of surf zone emissions is negligible in both seas. Nevertheless, they might be relevant because surf zone emissions were cut at an upper threshold in this study. Deactivating sea salt leads to a minor increase of NH4+ and NO3- and a minor decrease of SO42- concentrations. However, the overall effect is very low and lower than the deviation from measurements. Size resolved measurements of Na+, NH4+, NO3-, and SO42- are needed for a more detailed analysis on the impact of sea salt particles.

Abstract To clarify the relationship between the impact of phenological and/or artificial factors on seed quality, we measured the numbers of strobili on nematode-resistant Pinus densiflora clones grown in an immature and relatively small scale (700 m2) seed orchard. In addition, we established the clonal identities of all ramets, identified the paternal parent of the seeds, and assessed the resistance of seedlings to nematode infection. We also clarified the quantitative differences of strobili among clones; one clone produced 86.4% and 70.8% of all male strobili and female strobili, respectively. However, given that the total contamination ratio of the orchard was 82.0%, immigrant pollen had a larger impact on the success of actual crossing than phenology. Seedlings with a resistant maternal parent were resistant, even when their paternal parent was from outside the orchard. Two unselected clones were also planted in the seed orchard, one of which was not resistant and was associated with a maternal contribution of 34.7% of all seed stock. These findings suggest that, despite having a large impact on the crossing, immigrant pollen has a minor impact on seed resistance. Conversely, unselected and nonresistant clones have a marked impact on seed resistance. We concluded that artificial factors have larger impact on the seed quality than phenological factors in this orchard and the seeds will be of sufficient quality for supplying the market once nonresistant clones have been removed from the orchard.

Abstract Background Minor injuries are very common in the pediatric population and often occur in the home environment. Despite its prevalence, little is known about outcomes in children following minor injury at home. Understanding the impact of these injuries on children and their families is important for treatment, prevention, and policy. The objectives of our study were (1) To describe the distribution of short-term outcomes following pediatric minor injuries sustained at home and (2) To explore the relationship of injury type and patient and household demographics with these outcomes. Methods Children (n = 102) aged 0–7 years with a minor injury sustained at home were recruited in an urban pediatric emergency department as part of the Child Housing Assessment for a Safer Environment (CHASE) observational study. Each patient had a home visit following the emergency department visit, where five parent-reported outcomes were assessed. Relationships were explored with logistic regression. Results The most common type of injury was soft tissue (57.8 %). 13.2 % of children experienced ≥ 7 days of pain, 21.6 % experienced ≥ 7 days of abnormal activity, 8.9 % missed ≥ 5 days of school, 17.8 % of families experienced ≥ 7 days of disruption, and 9.1 % of parents missed ≥ 5 days of work. Families reported a total of 120 missed school days and 120 missed work days. Children who sustained a burn had higher odds of experiencing pain (OR 6.97), abnormal activity (OR 8.01), and missing school (OR 8.71). The parents of children who sustained a burn had higher odds of missing work (OR 14.97). Conclusions Families of children suffering a minor injury at home reported prolonged pain and changes in activity as well as significant school and work loss. In this cohort, burns were more likely than other minor injuries to have these negative short-term outcomes reported and represent an important target for interventions. The impact of these injuries on missed school and disruption of parental work warrants further consideration.

AbstractNeurological emergencies account for about one-third of the highest severity codes attributed in emergency pediatric departments. About 75% of children with acute neurological symptoms presents with seizures, headache, or other paroxysmal events. Life-threatening conditions involve a minor proportion of patients (e.g., less than 15% of children with headache and less than 5% of children with febrile seizures). This review highlights updated insights about clinical features, diagnostic workup, and therapeutic management of pediatric neurological emergencies. Particularly, details will be provided about the most recent insights about headache, febrile seizures, status epilepticus, altered levels of consciousness, acute motor impairment, acute movement disorders, and functional disorders, as well as the role of diagnostic tools (e.g., neuroimaging, lumbar puncture, and electroencephalography), in the emergency setting. Moreover, the impact of the current novel coronavirus disease2019 (COVID-19) pandemic on the evaluation of pediatric neurologic emergencies will also be analyzed.

Media Event

The focus of the present article is on the analysis of the influence exercised by media narratives on the Romanian audience's reconstructions of social movements from January-February 2012. The analysis was interested to show what are the aspects involved in the publicizing of this media event in Romania, by focusing on the event narrative built in such a way to transmit a particular significance related to the protest movements related to the crisis of the health public system in Romania. Two research methods were used in collecting the data: a survey on two hundreds Romanian respondents and quantitative content analysis of five national Romanian newspapers. As the results show, the high consumption of mass media messages does not determine whether the public adopts the media narratives concerning the events from the beginning of year 2012. At the same time, the analysis shows that in the case of the media events that took place in Romania in January-February 2012 the impact of the media narrative on the way in which the audience from Romania rebuilt those protests was a minor one and other factors had played a major role in triggering massive mass protests in Romania.
