Trauma, Violence, and Memory in African Child Soldier Memoirs
Authors: Hynd Stacey 
Published: March 2020

AbstractChild soldiers have been heavily involved in contemporary African warfare. Since the 1990s, the ‘child soldier crisis’ has become a major humanitarian and human rights project. The figure of the child soldier has often been taken as evidence of the ‘barbarism’, dehumanization and trauma generated by modern warfare, but such images can obscure the complex reality of children’s experiences of being part of armed groups during conflict. This article uses the published memoirs of former child soldiers from Sierra Leone, Sudan, Uganda, Eritrea and the Democratic Republic of the Congo to explore the instrumental and discursive nexus between child soldiers, memory, violence and humanitarianism. It assesses how (former-) children combatants remember and recount their experiences of war, and how these narratives can be shaped by humanitarian, literary and/or therapeutic framings. The article argues that these memoirs’ significance lies in their affective truths and what they reveal about children’s experience, and narrations, of war. Former child soldiers engage with, but also challenge, dominant contemporary humanitarian discourses surrounding childhood and violence to develop a ‘victim, savage, saviour, campaigner’ framework for their narratives. The article historically contextualizes the emergence of the ‘child soldier memoir’, before analysing the narratives of recruitment, indoctrination, and violence recounted by these former child soldiers, and their attempts to rework their identities in a post-conflict environment. It explores how former child soldiers narrate suffering and deploy discourses of trauma in their memoirs: some seeking to process wartime traumas, others leveraging their own suffering to position themselves as campaigners for those children still caught in conflict.
Making Votes Count with Internet Voting
Authors: Germann Micha 
Published: March 2020

AbstractThis paper reassesses the claim that electronic voting systems help voters to avoid common mistakes that lead to their votes remaining uncounted. While prior studies have come to mixed conclusions, I provide new, more robust evidence based on a case study of extended Internet voting trials in Geneva canton, Switzerland. The trials almost exclusively involved referendum votes. For causal identification I exploit the unique circumstance that federal safety legislation created a near-natural experiment, with some of the canton’s municipalities participating in the trials and others not. Using difference-in-differences estimation, I find that the residual vote rate decreased by an average of 0.3 percentage points if municipalities offered the possibility to vote online in addition to (mostly optically scanned) paper ballots. For cantonal measures, which are located towards the bottom of ballot papers in Geneva, the reduction increases to 0.5 percentage points. These remain relatively modest effects, and I find no evidence for a knock-on effect on electoral outcomes. However, on average only around 20% of votes were cast online where the opportunity existed, and online voting was most popular among voters with high levels of education. Despite the small effect sizes, the results of this study therefore point to the potential of Internet and, more generally, electronic voting technology to reduce avoidable voter mistakes.
Signatures of Coronal Loop Opening via Interchange Reconnection in the Slow Solar Wind at 1 AU

AbstractThe opening of closed magnetic loops via reconnection with open solar flux, so called “interchange reconnection”, is invoked in a number of models of slow solar wind release. In the heliosphere, this is expected to result in local switchbacks or inversions in heliospheric magnetic flux (HMF). When observed at 1 AU, inverted HMF has previously been shown to exhibit high ion charge states, suggestive of hot coronal loops, and to map to the locations of coronal magnetic separatrices. However, simulations show that inverted HMF produced directly by reconnection in the low corona is unlikely to survive to 1 AU without the amplification by solar wind speed shear. By considering the surrounding solar wind, we show that inverted HMF is preferably associated with regions of solar wind shear at 1 AU. Compared with the surrounding solar wind, inverted HMF intervals have lower magnetic field intensity and show intermediate speed and density values between the faster, more tenuous wind ahead and the slower, denser wind behind. There is no coherent signature in iron charge states, but oxygen and carbon charge states within the inverted HMF are in agreement with the higher values in the slow wind behind. Conversely, the iron-to-oxygen abundance ratio is in better agreement with the lower values in the solar wind ahead, while the alpha-to-proton abundance ratio shows no variation. One possible explanation for these observations is that the interchange reconnection (and subsequent solar wind shear) that is responsible for generation of inverted HMF involves very small, quiet-Sun loops of approximately photospheric composition, which are impulsively heated in the low corona, rather than large-scale active region loops with enhanced first-ionisation potential elements. Whether signatures of such small loops could be detected in situ at 1 AU still remains to be determined.

AbstractOctahedral molecular sieves (OMS-2) are an interesting form of manganese oxide with a 2 × 2 edge sharing tunnel structure and a cation positioned inside. Cryptomelane is an OMS-2 material with K+ cations within the crystalline tunnel and has been widely used in catalytic oxidation reactions, due to a mixed valency of Mn3+ and Mn4+ cations. Cryptomelane (K-OMS-2) can be modified by structural incorporation of various dopants and tunnel cations which can enhance the catalytic activity of the material. It also offers to be a promising alternative material for the low temperature emission control of combustion vehicles; particularly during cold start and low temperature conditions of diesel vehicles. In this work we used a one-pot sol–gel route to synthesize a range of manganese oxide based supports doped with Ce and CeZrO2, as alternative low temperature diesel oxidation catalysts. We have investigated the combination of manganese, ceria and zirconia in mixed oxide catalyst supports. The synthesized samples were loaded with 1 wt% Pt and their activity in the oxidation reactions of CO and C3H6, were compared with a commercial diesel oxidation catalyst with the same metal loading. The reductions in CO and C3H6 oxidation temperature T50 of 109 K and 81 K respectively was achieved compared to a commercial diesel oxidation catalyst.
Cadmium-induced endothelial dysfunction mediated by asymmetric dimethylarginine
Authors: Al-Naemi Hamda A. , Das Sandra Concepcion 
Published: March 2020

AbstractCadmium (Cd) is a naturally occurring toxic heavy metal with no known essential biological functions. Exposure to Cd increases the risk of cardiovascular disease by disrupting vascular homeostasis at the endothelium. The aim of the study was to evaluate the effect of chronic low-dose Cd on vascular structure and function. Fifty adult male Sprague Dawley rats were grouped and assigned to one of two treatments for 14 weeks. The control group received normal water for 14 weeks while the Cd-treated group received 15 mg Cd/kg B.W. as CdCl2 in water for 10 weeks. A subset of the Cd-treated group received 15 mg Cd/kg B.W. as CdCl2 in water for 10 weeks followed by 4 weeks of normal water. Results show an overall decline in vascular function and structure. Withdrawal of Cd treatment showed a considerable restoration of vascular structure and vasorelaxation function. Additionally, asymmetric dimethylarginine (ADMA) bioavailability was found to be lowered over time. Interestingly, the expression of eNOS in the Cd-treated group was found to be significantly elevated during the exposure by more than 3-fold in comparison with that in the control group. This protein expression was similar to the control group after the withdrawal of Cd treatment. Taken together, the results suggest that ADMA, an eNOS inhibitor, may play a role in altering endothelial function in the presence of cadmium. In conclusion, the findings indicate that even at low doses, Cd leads to endothelial dysfunction mediated by ADMA.

Published: March 2020

AbstractBariatric and metabolic surgery is associated with significant improvement in obesity-related comorbidities, but for patients with non-alcoholic fatty liver disease (NAFLD), clinical outcomes are dependent on the severity of liver disease, i.e. improvement of NAFLD in most patients but increased risks of fulminant hepatic failure and/or bleeding varices in patients with more advanced cirrhosis. Our study showed that absolute values of liver enzymes were poor indicator of risk of liver fibrosis. The use of AST/ALT ratio, Fib 4 or NAFLD scores were appropriate screening tools, with each risk score appearing to pick out a certain phenotype of patients based on age, BMI or individual values of ALT, AST or platelet count. There is lack of agreement in some cases between FIB-4 scores and NAFLD scores when ruling out patients at high risk of liver fibrosis. Meticulous screening of patients at risk of liver fibrosis is crucial in order to reduce the risk of liver-related complications following bariatric and metabolic surgery.

Published: March 2020

AbstractA wide range of software and hardware components are present in today’s production systems and plants using a variety of interfaces and data formats for information exchange on different levels of the system. To increase the traceability, the lifecycle management and providing a single point of source of component-specific data, the Digital Twin technology is proposed, linking different data sets tailored to the requirements of different kind of users (e.g., machines, technicians, logistics, manufacturing execution systems). The data exchange between entities in the manufacturing network relies on machine-readable, flexible and self-describing data formats. When implementing or integrating different components into complex systems, the interoperability challenge is a major concern to address by the system designers and becomes a central task for the creation and integration of Digital Twin technology. In this paper, we evaluate different formats that are used in real environments and create a requirements framework for an ideal format for exchanging flexible and self-describing data in context of optical components manufacturing process and their special requirements.

AbstractAbundant coal resources that were previously neglected due to a crude oil boom need revitalisation and integration into the national electricity mix to address the energy demands of the Nigerian population. Selected coal samples from the Benue Trough sedimentary basin in Nigeria were examined by various techniques, including proximate and ultimate analyses, organic petrography, Fourier transform infrared ray spectroscopy, and thermogravimetric analysis. Based on vitrinite reflectance, the Lafia-Obi (OLB), Garin Maiganga (GMG), Imiegba (IMG), and Okaba (OKB) coals are classified as subbituminous, while the Lamja1 (LMJ1), Lamja2 (LMJ2) and Chikila (CHK) coals are high volatile B bituminous. The Enugu (ENG) coal is on the boundary between subbituminous and high volatile C bituminous. Organic petrographic results indicate vitrinite and fusinite contents steadily increase from the Lower Benue Trough coals to the Upper Benue Trough coals, while semifusinite and total mineral contents follow a reverse pattern. Thermal decomposition occurred in three stages, i.e., drying, devolatilization, and coke formation above 700 °C; and the coal reactivity follows the following order, ENG > IMG > IGH > CHK > LMJ > OKB > GMG > LFB. The higher temperatures (above 900 °C) are required to decompose the coals for efficient energy recovery. The LMJ1, LMJ2, OLB, CHK, GMG, and OKB coals can be exploited for electricity power generation. However, the Imeagha and Enugu coals are best suitable for both cement and power generation.
International Valuation Standards (IVS) – Bedarf, Reichweite, Würdigung, diskutiert anhand der Bewertung von Unternehmen und Goodwill
Authors: Ballwieser Wolfgang 
Published: March 2020

ZusammenfassungDer Beitrag zielt auf eine Bedarfsanalyse des International Valuation Standards Council (IVSC) und der von ihm entwickelten International Valuation Standards (IVS) aus deutscher Sicht. Die akademische Beschäftigung mit IVSC und IVS ist bisher rudimentär und erschöpft sich weitgehend in einer Wiedergabe von Standards. Diese Sichtweise zu erweitern ist das übergeordnete Ziel des Beitrags. Betrieben wird die Analyse für die Unternehmens- und Goodwillbewertung, denn zur Unternehmensbewertung existieren IVS und zur Goodwillbehandlung äußert sich das IVSC. Dies erlaubt einen Vergleich mit der ausdifferenzierten Unternehmensbewertung in Deutschland und mit den ökonomischen Resultaten zum Informationswert der Wertminderungen von Goodwill.

Published: March 2020

AbstractIn this work, porous titanium (Ti) foams were successfully produced using spark plasma sintering technique at four different temperatures (up to 650 °C), in conjunction with vacuum sintering (used as a post-treatment) at a constant temperature of 1200 °C. To obtain a porous structure, 60 vol% of sodium chloride was included as a pore spacer, with the addition of polyethylene glycol solution for Ti–NaCl interparticle binding. The work aimed at studying the effect of sintering temperature on the final pore features and compression resistance of the porous titanium foams. X-ray diffraction and scanning electron microscopy as characterization techniques were used to analyze phases and pore evolutions, respectively. The results showed that the pore characteristics and the final porosity of porous titanium foams profoundly depend on the sintering temperature. The lowest porosity of approximately 53.9 vol%, with denser pore walls, was seen at the highest sintering temperature. Such foams sintered at 650 °C can resist the compression stress as high as 123 MPa while exhibiting the stiffness value of 8.1 GPa. The results indicate that the porous Ti foams produced have great potential for applications in hard tissue engineering.

Published: March 2020

Abstract
Background
High level of comorbidity between bipolar disorder or schizophrenia and cardiovascular diseases (CVD) in clinical practice may contribute to drug–drug interactions between medications used in these conditions. The aim of this study was to evaluate harmful interactions between antipsychotics and medications used in treatment of CVD.

Methods
The analysis of 52 cases of adverse reactions with a clinical picture indicates that they were the result of the combination of antipsychotic with cardiovascular medications.

Results
The highest number of interactions with antipsychotics was recorded among beta-blockers (n = 13, 25% of all cases), including cardiac arrhythmias [atrial fibrillation (n = 1): risperidone plus atenolol; bradycardia (n = 1): perphenazine with metoprolol; ventricular arrhythmias: sertindole with metoprolol (n = 1) and ziprasidone with sotalol (n = 3)] and hypotension [chlorprotixene with nebivolol or metoprolol (n = 2)]. 12 cases concerned statins—myalgia, myopathy, or creatine kinase elevation appeared after combination of atorvastatin with haloperidol (n = 1), quetiapine (n = 3) or risperidone (n = 1), and simvastatin with quetiapine (n = 5) or risperidone (n = 2). There were also cases of interactions observed for the use of antipsychotics with anti-arrhythmic drugs (amiodarone, flecainide, propafenone) (n = 11), calcium channel blockers (n = 6), and other cardiac medications: clonidine, dabigatran, doxazosin, ivabradine, and losartan (n = 10).

Conclusions
Due to a high risk of interactions and related adverse effects, particular attention should be paid while using cardiovascular medications with antipsychotics. Clinical decisions should be preceded by a detailed analysis of safety, risk–benefit ratio to search for, as safe as possible, drug combinations.
Prosper Weil and the Mask of Classicism
Authors: Tasioulas John 
Published: March 2020

Prosper Weil's scintillating intervention of 1983 warned against pathological doctrinal tendencies that threatened to “disable international law from fulfilling what have always been its proper functions.” Weil concluded his sweeping critique of these supposed pathologies with an urgent call for remedial action: “[A]ll is not yet lost . . . . There is still time for jurists to react.” But, as José Alvarez points out in his contribution to this symposium, the manifestations of “relative normativity” that Weil decried—such as the doctrine of jus cogens and the transmutation of customary law into universal law—have only entrenched themselves more firmly in the decades since his famous article was published. So, what is the point of engaging with “Towards Relative Normativity in International Law?” today beyond its historical significance as a celebrated, but ultimately failed, rallying cry against the doctrinal revolution that has swept over international law in the period since decolonization?

ABSTRACTObjective:Anesthesiologists play a pivotal role in mass-casualty incidents management. Disaster medicine is part of the anesthesiologist’s core skills; however, dedicated training is still scarce and, often, it does not follow a standardized program.Methods:We designed and delivered a crash course in disaster medicine for Italian anesthesiology residents participating in the nationwide program, Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) Academy Critical Emergency Medicine 2019. Residents totaling 145, from 39 programs, participated in a 75-minute workstation on the principles of disaster management. Following this, each participant was involved in a full-scale mass-casualty drill. A plenary debriefing followed to present simulation data, maximize feedback, and highlight all situations needing improvement.Results:Overall, participant performance was good: Triage accuracy was 85% prehospital and 84% in-hospital. Evacuation flow respected triage priority. During the debriefing, residents were very open to share and reflect on their experiences. A narrative qualitative analysis of the debriefing highlights that many participants felt overwhelmed by events during the exercise. Participants in coordination positions shared how they appreciated the need to switch from a clinical mindset to a managerial role.Conclusion:This was an invaluable experience for anesthesiology trainees, providing them with the skill set to understand the fundamental principles of a mass-casualty response.
On Origins and Species: Hegel on the Genus-Process
Authors: Lindquist Daniel 
Published: March 2020

AbstractThere is a broad consensus in the literature that in the section on ‘The Genus’ in theScience of Logic, Hegel argues that any living being must exist among other instances of its kind, with which it reproduces to create future generations, and out of which it was itself produced. This view is not only hard to motivate philosophically, it also seems to contradict many things Hegel says elsewhere in his system about the details of living nature, especially concerning the reality of spontaneous generation. After an examination of the secondary literature on ‘The Genus’, I offer an alternative view of this section, which I call ‘the Modal Reading’. The Modal Reading sees the language of pluralities in ‘The Genus’ as really Hegel's peculiar way of articulating certain modal features of thoughts about the living: to grasp a living individual as living, we need to distinguish not only between this individual and its environment, but also between the things this individual actually does and other possibilities which it does not actualize. The Modal Reading has a logical motivation insofar as it articulates what is needed to think of a living being as living, but it also avoids saddling Hegel with the problematic entailments he is usually read as taking on in this section. A further upshot of the Modal Reading is that approaching Hegel in this way provides us with a way to see Hegel as defending a non-nominalistic alternative to essentialist accounts of living kinds. Finding a way to read ‘The Genus’ which coheres with Hegel's views elsewhere in his system thus shows Hegel to have been an especially subtle and penetrating thinker, with continuing relevance for the philosophy of biology.
