Evaluating the Polish NAPs: Lessons for the Future Implementation of the UN Guiding Principles on Business and Human Rights
Authors: Kilanowski Marcin 
Published: March 2023

AbstractSince their adoption, the UN Guiding Principles on Business and Human Rights have become crucial to intensify actions to protect human rights in the context of business conduct. Numerous countries, including Poland, have adopted National Action Plans (NAPs). Taking into account the years that have passed, it is worth assessing the implementation of their goals. Guidelines for the preparation of NAPs on business and human rights of the United Nations Working Group on Business and Human Rights (UNWG) are helpful in assessing the Polish NAPs. This Development in the Field piece concludes that every NAP should begin with an assessment that would help identify areas where there is a need to implement necessary policies. Such an assessment could be used to compare the initial stage with future achievements. It should rely on clear milestones mentioned in NAPs, and on key performance indicators to assess effectiveness while also relying on inclusive decision-making processes. Unfortunately, this was not the case with the two Polish NAPs.
The semantic representation of food is shaped by cultural experience
Authors: Mazzuca Claudia , Majid Asifa 
Published: March 2023

AbstractWhile eating is universally salient, food habits vary greatly even across similar western cultural groups. Italians, for example, are renowned pasta consumers whereas this habit is less pervasive in other western cultures. This variability might shape the conceptualization of food of different cultural groups. Against this backdrop, it has been proposed the semantic representation of food is universally organized along two main axes, with natural food (e.g., vegetables, fruit) relying more on sensory properties and manufactured food (e.g., pasta) relying more on functional properties. In this exploratory study, we compared the semantic representation of pasta, vegetables, and fruit across Italian and English-speaking participants with a free-listing task. We find the representation of pasta is not restricted to functional properties. Moreover, Italian and English speakers differed both quantitatively and qualitatively in their representation of pasta. Italians produced more exemplars of pasta than English-speaking participants, and their conceptual organization of pasta also included fine-grained distinctions (e.g., egg-based vs. flour-and-water pasta), whereas English-speaking participants mostly focused on perceptual components (e.g., long) – even when accounting for differential consumption, cooking, and preparation experience of pasta. Our results suggest that culture-specific experiences can shape the conceptualization of food.
A network community detection method with integration of data from multiple layers and node attributes

Published: March 2023

AbstractMultilayer networks are in the focus of the current complex network study. In such networks, multiple types of links may exist as well as many attributes for nodes. To fully use multilayer—and other types of complex networks in applications, the merging of various data with topological information renders a powerful analysis. First, we suggest a simple way of representing network data in a data matrix where rows correspond to the nodes and columns correspond to the data items. The number of columns is allowed to be arbitrary, so that the data matrix can be easily expanded by adding columns. The data matrix can be chosen according to targets of the analysis and may vary a lot from case to case. Next, we partition the rows of the data matrix into communities using a method which allows maximal compression of the data matrix. For compressing a data matrix, we suggest to extend so-called regular decomposition method for non-square matrices. We illustrate our method for several types of data matrices, in particular, distance matrices, and matrices obtained by augmenting a distance matrix by a column of node degrees, or by concatenating several distance matrices corresponding to layers of a multilayer network. We illustrate our method with synthetic power-law graphs and two real networks: an Internet autonomous systems graph and a world airline graph. We compare the outputs of different community recovery methods on these graphs and discuss how incorporating node degrees as a separate column to the data matrix leads our method to identify community structures well-aligned with tiered hierarchical structures commonly encountered in complex scale-free networks.
The prospects for European aerospace transporters - Part 1: The derivation of a first order parametric method for estimating the development cost of aerospace transporters
Authors: Ashford D. M. , Collins P. Q. 
Published: March 2023

SummaryManned spacecraft cost typically ten times as much to develop as advanced technology prototype aeroplanes of similar weight. For example, the Hermes spaceplane, which is designed to be launched into orbit by the expendable Ariane 5, has an estimated development cost of $4 billion, which is about ten times greater than the cost of the Experimental Aircraft Programme (EAP) demonstrator of the European Fighter Aircraft ($350 million). The Hermes spaceplane and the EAP are of comparable size and weight and both use very advanced technology. The EAP is already more mature than Hermes would become because, although the EAP is only a prototype, it has made more flights than are planned for Hermes over its entire operational career.This part of the paper attempts to identify the factors which explain this difference in cost and then to determine which of them would apply to fully reusable, piloted, aeroplane-like launchers, i.e. aerospace transporters.
Sycomores concept
Authors: Dulck J. F. , Larregola R. , Mariet G. , Rouffet D. 
Published: March 2023

AbstractMost organisations predict that the expansion of satellite applications to new areas, such as land mobile communications, will be in a rapid worldwide growth phase up to the end of the century. The geographical and geometrical link properties along with the economic aspects (with the projected saturation of the frequency allocation), have led communications services to consider non-conventional orbits for the near future. This paper presents an analysis of the fundamental problems and a statement on the short-term technical solutions within the particular framework of a general land mobile communication mission. The results of these efforts led the authors to propose the Sycomores concept, which is at least a twin satellite system located on particular inclined elliptical geosynchronous orbits.
Fracture analysis of complex shaped structures by numerical and experimental methods
Authors: Marchetti M. , La Barbera A. , Morganti F. 
Published: March 2023

SummaryThe problem of fracture characterisation of geometrically complex structures is considered. Numerical and experimental strategies are used to evaluate stress intensity factors and elastic fields for cracked thin shell and plate structures. Theoretical analyses, using different order theories, are also performed in order to evaluate stress and energy distributions in the neighbourhood of the crack tip. A geometrically complex strut component is analysed by using a ‘p-convergent’ finite element code based on hierarchic elements and on the high degree of approximating functions. Actual fracture modes, for different crack locations, have been singled out and the elastic fields are compared to those referring to cracked plate and shell structures. An experimental investigation, using the optical method of caustics, has been also performed and stress intensity factors for several crack configurations have been calculated. The numerical investigations have shown the ability of the p-version finite element method to provide accurate computation of local stress values and to quote the convergence of the numerical calculations. The caustics method has confirmed its accuracy for evaluating stress intensity factors, even for complex structures.
NEUTRAL ARMS TRANSFERS AND THE RUSSIAN INVASION OF UKRAINE
Authors: Clancy Pearce 
Published: March 2023

AbstractSince the beginning of the Russian invasion of Ukraine in February 2022, numerous Western States have supplied Ukraine with arms, munitions and war material, in ostensible breach of their obligations as neutral, non-participating States. States have failed to provide any legal explanation for such transfers, leaving the task to scholars and commentators to provide legal argumentation as to the compatibility of arms transfers to victims of aggression with neutral duties. This article analyses and seeks to evaluate these arguments in favour of ‘qualified neutrality’ and assess which of the proposed grounds, if any, are the most compelling.
Medical Legitimacy: Childbirth, Pluralism, and Professionalization in Nigeria's Faith-Based Aladura Birthing Homes
Authors: Williams Ogechukwu E. 
Published: March 2023

AbstractIn the wake of the Aladura (prayer people) religious movement of the late 1920s, a site of childbirth that relied primarily on faith healing emerged in Nigeria under the Christ Apostolic Church (CAC). This practice of faith-based delivery remained informal until 1959 when it evolved into a permanent structure with a professional guild of midwives, codified practices, and trained personnel. This article explores the advent of CAC's faith-based maternity practice, notably its faith home midwifery school, and how the faith home transformed its identity from the informal realms of religious healing to a recognized religious entity that offered primary maternity care based on the principles of faith healing. By examining the professionalization of Aladura faith homes, I highlight questions of legitimacy allocation in postcolonial Africa and how CAC navigated this process by courting legitimacy from state-backed institutions and sociocultural frameworks.

Published: March 2023

AbstractObjectives:Early-life socioeconomic status (SES) and adversity are associated with late-life cognition and risk of dementia. We examined the association between early-life SES and adversity and late-life cross-sectional cognitive outcomes as well as global cognitive decline, hypothesizing that adulthood SES would mediate these associations.Methods:Our sample (N = 837) was a racially and ethnically diverse cohort of non-Hispanic/Latino White (48%), Black (27%), and Hispanic/Latino (19%) participants from Northern California. Participant addresses were geocoded to the level of the census tract, and US Census Tract 2010 variables (e.g., percent with high school diploma) were extracted and combined to create a neighborhood SES composite. We used multilevel latent variable models to estimate early-life (e.g., parental education, whether participant ever went hungry) and adult (participant’s education, main occupation) SES factors and their associations with cross-sectional and longitudinal cognitive outcomes of episodic memory, semantic memory, executive function, and spatial ability.Results:Child and adult factors were strongly related to domain-specific cognitive intercepts (0.20–0.48 SD per SD of SES factor); in contrast, SES factors were not related to global cognitive change (0.001–0.01 SD per year per SD of SES factor). Adulthood SES mediated a large percentage (68–75%) of the total early-life effect on cognition.Conclusions:Early-life sociocontextual factors are more strongly associated with cross-sectional late-life cognitive performance compared to cognitive change; this effect is largely mediated through associations with adulthood SES.
Irreversible and Large‐Scale Heavy Metal Pollution Arising From Increased Damming and Untreated Water Reuse in the Nile Delta

AbstractEgypt observes one of the highest water budget deficits in Africa that is mainly compensated by intensive reuse of untreated agricultural drainage water in the Nile Delta. The implications of untreated water reuse on increasing soil pollution levels remain poorly characterized; however, a large‐scale pollution can compromise crop production and water quality. To address this deficiency, we evaluate the level of heavy metal pollution in the Nile Delta, identify its sources and explore the implications of damming on heavy metal concentration using integrated pollution indicators and statistical modeling. Pollution indicators show moderate to very high contamination by Pb, Ni, Cr, Cd, Cu, and Zn, with unprecedented Cd levels in the sediments (up to 72.0 ppm) and a northward increase in pollution levels. Statistical modeling and historical datasets reveal the association of Cd and Fe on both Nile branches and the clustering of Pb, Ni, Cu, Zn and Cr, which attribute the heavy metal concentrations to the cumulative addition of untreated agricultural drainage water (9.5 BCM/yr) and wastewater. These processes introduced an accelerated pollution in the Nile Delta system. Though, conservation measures are crucial to reverse this degradation, yet the increasingly engineered Nile flow, the low gradient of the delta and the active silting impede heavy metal flushing causing irreversible pollution. Our findings alarm future increase in heavy metal pollution in response to increased untreated drainage water reuse to mitigate the impacts of ongoing upstream damming and call for implementing international cooperative agreements for integrated water management along the Nile River.
Shear Velocity Evidence of Upper Crustal Magma Storage Beneath Valles Caldera
Authors: Wilgus Justin , Schmandt Brandon , Maguire Ross , Jiang Chengxin , Chaput Julien 
Published: March 2023

AbstractValles Caldera was formed by large rhyolitic eruptions at ∼1.6 and 1.23 Ma and it hosts post‐caldera rhyolitic deposits as young as ∼69 ka, but the contemporary state of the magmatic system is unclear. Local seismicity beneath Valles Caldera is rare and shear‐velocity (Vs) structure has not been previously imaged. Here, we present the first local Vs tomography beneath Valles Caldera using ambient noise Rayleigh dispersion from a ∼71 km transect of nodal seismographs with mean spacing of ∼750 m. An ∼6 km wide low‐Vs anomaly (Vs < 2.1 km/s) is located at ∼3–10 km depth within the 1.23 Ma caldera's ring fracture. Assuming magma in textural equilibrium, the new tomography suggests that melt fractions up to ∼17%–22% may be present within the upper crustal depth range where previously erupted rhyolites were stored.
A Global Quantification of the Physical Processes Leading to Near‐Surface Cold Extremes
Authors: Röthlisberger Matthias , Papritz Lukas 
Published: March 2023

AbstractKinematic backward trajectories are used to globally quantify the contributions of temperature advection, adiabatic compression and diabatic processes to near‐surface temperature anomalies (hereafter ) during the coldest day of each year (TN1day events) based on ERA5. Diabatic cooling dominates TN1day anomalies in the climatologically coldest regions, while advection forms TN1day anomalies over most ocean regions. Over most extratropical land masses, TN1day anomalies arise from a combination of both processes. The mean age and formation distance of TN1day anomalies vary strongly in space, from one to 8 days, and 500–5,500 km, respectively. Five distinct types of TN1day events are identified from these physical and spatio‐temporal characteristics, and their geographical occurrence is investigated. Furthermore, advective, adiabatic and diabatic contributions typically cancel each other partially, but less so for the most intense TN1day events, which occur when the atmosphere's ability to dampen near‐surface temperature anomalies is limited.

Published: March 2023

AbstractThe ability of satellite instruments to accurately observe long‐term changes in atmospheric temperature depends on many factors including the absolute accuracy of the measurement, the stability of the calibration of the instrument, the stability of the satellite orbit, and the stability of the numerical algorithm that produces the temperature data. We present an example of algorithm instability recently discovered in the temperature data set from the SABER instrument on the NASA TIMED satellite. The instability resulted in derived temperatures that were substantially colder than anticipated from mid‐December 2019 to mid‐2022. This algorithm‐induced change in temperature over 1 to 2 years corresponded to the expected temperature change over several decades from increasing anthropogenic CO2. This paper highlights the importance of algorithm stability in developing Geospace Data Records (GDRs) for Earth’s mesosphere and lower thermosphere. A corrected version (Version 2.08) of the temperatures from SABER is described.
Insights Into the Dynamics of Vegetated Alternate Bars by Means of Flume Experiments
Authors: Calvani G. , Francalanci S. , Solari L. 
Published: March 2023

AbstractAlternate bars are bedforms recognizable in straight or weakly curved channels as a result of riverbed instability. The length and height of alternate bars scale with the river width and the water depth, respectively. During low water stages, alternate bars become exposed and can be colonized by riparian vegetation. The effects of established plants on the morphodynamics of alternate bars have been poorly investigated. In this work, we focus on the effects induced by rigid vegetation on the dynamics and morphology of previously developed alternate bars in a straight channel by means of flume experiments. We investigate three different spatial densities of plants to reproduce scenarios of vegetation establishment. The results illustrate that vegetation alters both the altimetric and planimetric characteristics of bar patterns. In particular, as compared to bare‐bed bars, vegetated bars have a higher wave amplitude and scour, and this effect becomes stronger with plant density. Moreover, they exhibit decreasing wavenumbers according to vegetation density. A comparison with previous fundamental work for the planimetric instability of straight channels with bare‐bed alternate bars, suggests that the established vegetated bars may promote the transition to river meandering.
Windmapper: An Efficient Wind Downscaling Method for Hydrological Models
Authors: Marsh Christopher B. , Vionnet Vincent , Pomeroy John W. 
Published: March 2023

AbstractEstimates of near‐surface wind speed and direction are key meteorological components for predicting many surface hydrometeorological processes that influence critical aspects of hydrological and biological systems. However, observations of near‐surface wind are typically spatially sparse. The use of these sparse wind fields to force distributed models, such as hydrological models, is greatly complicated in complex terrain, such as mountain headwaters basins. In these regions, wind flows are heavily impacted by overlapping influences of terrain at different scales. This can have a great impact on calculations of evapotranspiration, snowmelt, and blowing snow transport and sublimation. The use of high‐resolution atmospheric models allows for numerical weather prediction (NWP) model outputs to be dynamically downscaled. However, the computation burden for large spatial extents and long periods of time often precludes their use. Here, a wind‐library approach is presented to aid in downscaling NWP outputs and terrain‐correcting spatially interpolated observations. This approach preserves important spatial characteristics of the flow field at a fraction of the computational costs of even the simplest high‐resolution atmospheric models. This approach improves on previous implementations by: scaling to large spatial extents O(1M km2); approximating lee‐side effects; and fully automating the creation of the wind library. Overall, this approach was shown to have a third quartile RMSE of 1.8 and a third quartile RMSE of 58.2° versus a standalone diagnostic windflow model. The wind velocity estimates versus observations were better than existing empirical terrain‐based estimates and computational savings were approximately 100‐fold versus the diagnostic model.
Exploring the Optimal Location of Pumps as Turbines Within Branched Irrigation Networks by Global Optimization

Published: March 2023

AbstractIn this study a new procedure to address the optimization of the location and selection of pumps as turbines (PATs) within irrigation networks is presented in order to reduce network pressure and recover energy. The proposed procedure consists of two steps: in the first step the optimization of the location of devices is performed, then the optimal selection and regulation is investigated in the second step. Two new mixed integer non‐linear models have been developed and a global optimization solver has been employed to perform both optimization procedures. The procedure has been tested on a real irrigation network in Spain. The entire 2015 irrigation season has been used to properly model the water demand within the system. According to the results, the optimal solution consists of 5 PATs, installed in the middle region of the system. The investment cost has been estimated as 169,278 € with a payback period of almost 4.2 irrigation seasons. According to the solution, the effective amount of produced energy is equal to 289 MWh if the system is properly regulated and the pressure exceeding the minimum requirements is exploited to produce energy. Compared to other studies in literature focused on irrigated agriculture, the number of PATs is not fixed but rather it results from the maximization of the energy recovery and the minimization of capital costs, simultaneously. Moreover, the proposed procedure relies on a deterministic approach, achieving promising results in terms of accuracy.
