Authors: Onyishi Ike E. , Amaeshi Kenneth , Ugwu Fabian O. , Enwereuzor Ibeawuchi K. 
Published: January 2020

ABSTRACTThere is a growing call to understand the influence of corporate social responsibility (CSR) on organizational outcomes, especially in developing economies. Given the strong link between organizational citizenship behavior (OCB) and organizational performance and survival, on one hand, and the constant need in the literature to understand their antecedents, on the other hand, this study adopts the social cognitive theory to examine the relationship between employees’ perceptions of their organizations’ engagement in CSR and their individual engagement in OCB in Nigeria. Based on the relevance of organizational learning culture to both CSR and OCB, the study further examines the mediating role of organizational learning culture in the relationship between employees’ perceptions of their organization's CSR engagement and their individual engagement in OCB. We tested these relationships in a sample of 254 employees drawn from banking, oil and gas, manufacturing and service industries. The results showed that there is a significant positive relationship between employees’ perceptions of their organizations’ engagement in CSR and their exhibition of OCB. This relationship is mediated by organizational learning culture. The implications of the results for CSR, especially in non-enabling institutional contexts, were discussed.
The Prusso-German General Staff and the Herero Genocide
Authors: Grawe Lukas 
Published: January 2020

AbstractHistorians have examined the Herero genocide in German South West Africa extensively. The role of the Prusso-German general staff has received only rudimentary treatment, however. The following study focuses on the actions of this institution and its chief. Evidence indicates that initially and with varying degrees of success the general staff was heavily involved in German military actions. After the Battle of Waterberg, however, the local military commander, Lieutenant General Lothar von Trotha, fought his own war. Meanwhile, the general staff gravitated toward a different role: shielding Trotha from criticism emanating from German civilian leaders and the public. The impulse to protect sprang not only from a harmony of views about the annihilation of the Herero, but also from an urge to preserve the prestige of the German military after unexpected losses at the hands of “African savages.” In fact, the Prusso-German general staff was complicit in, if not partly responsible for, the conduct of genocidal warfare in GSWA.

Published: January 2020

AbstractObjectiveTo determine whether patients would have equivalent or improved outcomes when receiving non-surgical management versus surgical removal for vocal process granulomas.MethodsA chart review was performed for 53 adults with vocal process granulomas. All patients received baseline anti-reflux treatment consisting of twice-daily proton pump inhibitors and vocal hygiene education. Further treatment approaches were divided into non-surgical (i.e. inhaled corticosteroids, voice therapy, botulinum toxin injections) and surgical groups. Subjective parameters (Voice Handicap Index 10 and Reflux Symptom Index) and outcomes were tabulated and statistically compared. Cause of granuloma was also analysed to determine if this influenced outcomes.ResultsOf 53 patients, 47 (89 per cent) experienced reduction in granuloma size, while 37 (70 per cent) experienced complete resolution. The rate of complete granuloma resolution after initial treatment strategy alone was significantly higher in non-surgical compared to surgical patients (67 and 30 per cent, respectively; p = 0.039). No difference in outcome was seen between iatrogenic and idiopathic granulomas.ConclusionNon-surgical patients were more likely to experience initial treatment success than those who underwent surgical removal. Continued emphasis should be placed on conservative treatment options prior to surgery for patients with this condition.
RECONSIDERING THE SOUTHERN EUROPEAN MODEL: MARITAL STATUS, WOMEN'S WORK AND LABOUR RELATIONS IN MID-EIGHTEENTH-CENTURY PORTUGAL
Authors: Ribeiro da Silva Filipa , Carvalhal Hélder 
Published: January 2020

ABSTRACTChallenging current ideas in mainstream scholarship on differences between female labour force participation in southern and north-western Europe and their impact on economic development, this article shows that in Portugal, neither marriage nor widowhood prevented women from participating in the labour market of mid-eighteenth-century. Our research demonstrates that marriage provided women with the resources they needed to work in various capacities in all economic sectors.This article also argues that single Portuguese women had an incentive to work and did so mostly as wage earners. Finally, the comparison of our dataset on female occupations from tax records with other European cases calls for a revision of the literature and the development of a more nuanced picture of the north-south divide.
Unilaterally Constrained Motion of a Curved Surgical Tool
Authors: Dahroug Bassem , Tamadazte Brahim , Andreff Nicolas 
Published: January 2020

SUMMARYConstrained motion is essential for varying robotics tasks, especially in surgical robotics, for instance, the case of minimally invasive interventions. This article proposes generic formulations of the classical bilateral constrained motion (i.e., when the incision hole has almost the same diameter as that of the tool) as well as unilaterally constrained motion (i.e., when the hole incision has a larger diameter compared to the tool diameter). One of the latter constraints is combined with another surgical task such as incision/ablation or suturing a wound (modeled here by 3D geometric paths). The developed control methods based on the hierarchical task approach are able to manage simultaneously the constrained motion (depending on the configuration case, i.e., bilateral or unilateral constraint) and a 3D path following. In addition, the proposed methods can operate with both straight or curved surgical tools. The proposed methods were successfully validated in various scenarios. Foremost, a simulation framework was proposed to access the performances of each proposed controller. Thereafter, several experimental validations were carried out. Both the simulation and experimental results have demonstrated the relevance of the proposed approach, as well as promising performances in terms of behavior as well as accuracy.

SummaryIn vitro embryo production (IVEP) is a procedure that can promote genetic improvement in a short time frame. However, the success rates obtained with this biotechnology in water buffaloes are still inconsistent, and can be associated with the high concentration of lipids in the cytoplasm of oocytes and embryos. The objective of this study was to evaluate the effects of reduced concentration of fetal bovine serum (FBS) and/or use of l-carnitine during in vitro maturation (IVM) on the preimplantation development and lipid accumulation in bubaline embryos. In a first experiment, the lowest concentration of FBS in the IVM medium (0%, 2.5%, 5% or 10%) was determined, and the lowest concentration that maintained good embryo development rates was 5%. In a second experiment, the addition of 5 mM of l-carnitine into the maturation medium was evaluated. The blastocysts produced were submitted to lipid evaluation involving staining followed by observation using optical (Oil Red O) and confocal (BODIPY 493/503) microscopy. No difference was observed between the 5% and 10% FBS groups, which were superior to the 0% and 2.5% groups. Furthermore, the performance of the groups treated with 5% and 10% FBS was better than the groups supplemented with l-carnitine. There was no difference regarding embryo lipid accumulation. The results indicated that it is possible to reduce the FBS concentration to 5% in in vitro maturation medium for production of bubaline embryos, and supplementation with 5 mM l-carnitine does not increase embryo production.
Mithridates and theOracle of Hystaspes: Some dating issues
Authors: DOBRORUKA VICENTE 
Published: January 2020

AbstractThe dating of the so-calledOracle of Hystaspesor its Vorlage has for long been a major problem among scholars. This article attempts to articulate some issues present in the Oracle and similar or identical ones known to have been used in Mthridates’ VI Eupator propaganda. This can help not only dating the Oracle itself but also solve dating problems in Persian apocalyptic texts, whose dating may be pushed backwards.

AbstractAim:The aim of this work was to study the acceptability of plans prepared for prostate patients treated by volumetric modulated arc therapy (VMAT) with the vision to evaluate the quality of plans and test pre-treatment quality assurance (QA).Material methods:VMAT plans of 35 patients, planned on the Eclipse Treatment Planning System (Aria 15), were included in the study. Plan acceptability was checked using statistical analysis, which includes homogeneity index, radical and median homogeneity index, coverage and uniformity index. Dose–volume histograms (DVH) of the plans were also studied to check prescribed dose (PD),Dmax,Dmin,D5andD95. Portal dosimetry was also done by gamma analysis using 3%/3 mm criterion. SD and mean SD error were also calculated and analysed.Results:Statistical analysis showed a mean HI of 1·054, coverage 0·959, UI 1·055, mDHI 0·962 and rDHI 0·866. SD of HI, coverage, UI, mDHI and rDHI was 0·019, 0·019, 0·014, 0·013 and 0·030, respectively. From the DVHs, mean ofD5,D95,DminandDmaxwas calculated at 6,252·9, 5,757·4, 6,413·3 and 5,657·7 cGy, respectively, with a prescribed dose of 6,000 cGy. According to gamma analysis, area gamma < 1 was 99·12% with a tolerance limit of 95%, maximum gamma was 1·466 with a tolerance limit of 3·5, average gamma was 0·388 with a tolerance limit of 0·5, area gamma > 1·2 was 0·242% with a tolerance limit of 0·5%, maximum dose difference was 0·6 with a tolerance limit of 1·0 and average dose difference was 0·029 with a tolerance limit of 0·2.Conclusion:All three computations showed the results to be within acceptable limits. VMAT possesses a unique feature of delivering the whole treatment with only two rotations of the gantry. VMAT has an improved efficiency of delivery for equivalent dosimetric quality.
Dynamic microsimulation modelling of potential pension reforms in North Macedonia
Authors: Petreski Blagica , Petreski Marjan 
Published: January 2020

AbstractDue to structural and policy shifts, pension deficit in North Macedonia doubled over a decade and significantly outpaced the central budget deficit. The objective of the paper is to examine fiscal and development effects of few pension-reform designs. We constructed MK-PENS Dynamic Microsimulation Pension Model and simulated the effects of few reforms affecting one stakeholder and few combined reforms. Results robustly suggest that without reform and assuming only statutory pension adjustment, the deficit will remain as is. Simulated scenarios suggest that proposed pension reforms significantly reduce the pension deficit, with the most favourable results obtained within the combined scenarios of shared burden. Gradual introduction of reform's elements should come into play in case large political cost is envisaged.
Work after retirement: worklife transitions of career public employees
Authors: Clark Robert L. , Hammond Robert G. , Liu Siyan 
Published: January 2020

AbstractEngaging in paid employment after claiming retirement benefits may be an important avenue for individuals to work longer as life expectancies rise. After separating from one's career employer, individuals may engage in paid work to stay active or to supplement their current level of retirement savings or both. Individuals who choose not to work after claiming may be expressing their preference to stay retired, perhaps because their retirement income is sufficient. However, the decision to work after claiming may be driven by the lack of retirement planning and insufficient savings, while the lack of post-claiming work may reflect the inability to find adequate employment opportunities. We use administrative records merged with panel data from several surveys of public employees in North Carolina to study the decision to engage in paid work after claiming retirement benefits. More than 60% of active workers plan to work after claiming benefits, while only around 42% of the same sample of individuals have engaged in post-claiming paid work in the first few years after leaving public sector employment. Despite this gap, stated work plans are strongly predictive of actual post-claiming work behavior. Our final analysis uses self-reported measures to gauge the financial well-being of our sample in the early years after leaving career employment.

Published: January 2020

AbstractAlthough numerous Earthquake Early Warning (EEW) algorithms have been developed to date, we lack a detailed understanding of how often and under what circumstances useful ground motion alerts can be provided to end users. In particular, it is unclear how often EEW systems can successfully alert sites with high ground motion intensities. These are the sites that arguably need EEW alerts the most, but they are also the most challenging ones to alert because they tend to be located close to the epicenter where the seismic waves arrive first. Here we analyze the alerting performance of the Propagation of Local Undamped Motion (PLUM), Earthquake Point‐Source Integrated Code (EPIC), and Finite‐Fault Rupture Detector (FinDer) algorithms by running them retrospectively on the seismic strong‐motion data of the 219 earthquakes in Japan since 1996 that exceeded Modified Mercalli Intensity (MMI) of 4.5 on at least 10 sites (Mw4.5–9.1). Our analysis suggests that, irrespective of the algorithm, EEW end users should expect that EEW can often but not always provide useful alerts. Using a conservative warning time (tw) definition, we find that 40–60% of sites with strong to extreme shaking levels receive alerts withtw> 5 s. If high‐intensity shaking is caused by shallow crustal events, around 50% of sites with strong (MMI~6) and <20% of sites with severe and violent (MMI ≥ 8) shaking receive alerts withtw> 5 s. Our results provide detailed quantitative insight into the expected alerting performance for EEW algorithms under realistic conditions. We also discuss how operational systems can achieve longer warning times with more precautionary alerting strategies.
The Impact of Continuing CFC‐11 Emissions on Stratospheric Ozone

Published: January 2020

AbstractTrichlorofluoromethane (CFC‐11, CFCl3) is a major anthropogenic ozone‐depleting substance and greenhouse gas, and its production and consumption are controlled under the Montreal Protocol. However, recent studies show that CFC‐11 emissions have been near constant or increasing since 2002. In this study, we use a two‐dimensional chemistry‐climate model to investigate the stratospheric ozone response to a range of future CFC‐11 emissions scenarios. A scenario with future emissions sustained at 10 gigagrams per year (Gg/year) above the baseline WMO (2018) A1 scenario results in minor additional global (90°S–90°N) ozone depletion of 0.13% by 2100, and a 1.5‐year delay in the global ozone recovery to 1980 levels, relative to the baseline. A scenario with 72.5 Gg/year (the 2013–2016 average) sustained to 2100 results in a substantial 15% increase in effective equivalent stratospheric chlorine and nearly 1% additional global ozone depletion by 2100, with a 7.5‐year delay in the recovery to 1980 global ozone levels, relative to the baseline. The ozone response averaged over time has a strong linear dependence on the cumulative amount of future CFC‐11 emissions under a wide range of scenarios. The resulting ozone response sensitivity gives a simple metric relating the time‐averaged ozone change to the cumulative CFC‐11 emissions. This sensitivity has an inverse dependence on future greenhouse gas concentrations (CO2, CH4, and N2O). For the medium Intergovernmental Panel on Climate Change Representative Concentration Pathway‐6.0 scenario, the sensitivity per 1,000 Gg of cumulative CFC‐11 emissions is −0.1% and −1% for global and Antarctic spring ozone, respectively.
Comparison of Reference Heights of O/N2 and ∑O/N2 Based on GUVI Dayside Limb Measurement

AbstractWe define a new thermospheric concept, the reference heights of O/N2, referring to a series of thermospheric heights corresponding to the fixed ratios of O to N2 number density. Here, based on Global Ultraviolet Imager (GUVI) limb measurement, we compare O/N2 column density ratio (∑O/N2) and the reference heights of O/N2. We choose the transition height of O and N2 (transition height hereafter), a special reference height at which O number density is equal to N2 number density, to verify the connection with ∑O/N2 during geomagnetically quiet periods. It is found that transition height and ∑O/N2 have noticeable negative correlation with correlation coefficient of ‐0.887. An empirical model of transition height (O/N2 model hereafter) is established based on nonlinear least‐squares‐fitting method. The considerable correlation (greater than 0.96), insignificant errors (less than 4%) and the great influencing weight of ∑O/N2 to reference heights indicate the validity of O/N2 model and the existence of quantitative relation between ∑O/N2 and transition height. Besides, it is verified that the similar quantitative relation also exists between ∑O/N2 and reference heights of other O/N2 values. Namely, using the O/N2 model coefficients, we can roughly get the whole altitude profiles of O/N2 within 6% precision for any given ∑O/N2.
Spatial Scale Effect of Surface Routing and Its Parameter Upscaling for Urban Flood Simulation Using a Grid‐Based Model

Published: January 2020

AbstractUrban catchments are characterized by a wide variety of complex juxtapositions and surface compositions that are linked to multiple overland flow paths. Their extremely high spatial heterogeneity leads to great sensitivity of hydrologic simulation to the scale variation of calculation units. Although extensive efforts have been made for investigating the scale effects and indicate its significance, less is understood of how routing features vary with spatial scales and further how the variation of routing features influences the hydrological response. In this paper, a grid‐based distributed urban hydrological model is applied to study spatial scale effects ranging from 10 to 250 m. Two parameters are proposed to quantitatively depict the routing features of overland flow specified for impervious and pervious areas. The results show that routing features are quite sensitive to spatial resolution. Large differences among simulations exist in the infiltration amounts attributed to the combined effects of the two routing parameters, which leads to opposite effects for both total flow volume and peak flow for various rainfall events. The relationship of the key model parameters at different spatial resolutions can be explicitly expressed by corresponding routing features. With this relationship, parameters transfer among different spatial scales can be realized to obtain consistent simulation results. This study further revealed the quantitative relationship between spatial scales, routing features, and the hydrologic processes and enabled accurate and efficient simulations required by real‐time flooding forecasting and land‐atmosphere coupling, while fully taking the advantages of detailed surface information.

Published: January 2020

AbstractCovalent organic frameworks with designable periodic skeletons and ordered nanopores have attracted increasing attention as promising cathode materials for rechargeable batteries. However, the reported cathodes are plagued by limited capacity and unsatisfying rate performance. Here we report a honeycomb-like nitrogen-rich covalent organic framework with multiple carbonyls. The sodium storage ability of pyrazines and carbonyls and the up-to twelve sodium-ion redox chemistry mechanism for each repetitive unit have been demonstrated by in/ex-situ Fourier transform infrared spectra and density functional theory calculations. The insoluble electrode exhibits a remarkably high specific capacity of 452.0 mAh g−1, excellent cycling stability (~96% capacity retention after 1000 cycles) and high rate performance (134.3 mAh g−1 at 10.0 A g−1). Furthermore, a pouch-type battery is assembled, displaying the gravimetric and volumetric energy density of 101.1 Wh kg−1cell and 78.5 Wh L−1cell, respectively, indicating potentially practical applications of conjugated polymers in rechargeable batteries.

Published: January 2020

AbstractIndividual differences in pain perception are of interest in basic and clinical research as altered pain sensitivity is both a characteristic and a risk factor for many pain conditions. It is, however, unclear how individual sensitivity to pain is reflected in the pain-free resting-state brain activity and functional connectivity. Here, we identify and validate a network pattern in the pain-free resting-state functional brain connectome that is predictive of interindividual differences in pain sensitivity. Our predictive network signature allows assessing the individual sensitivity to pain without applying any painful stimulation, as might be valuable in patients where reliable behavioural pain reports cannot be obtained. Additionally, as a direct, non-invasive readout of the supraspinal neural contribution to pain sensitivity, it may have implications for translational research and the development and assessment of analgesic treatment strategies.
