Instrumental or intrinsic? Human rights alignment in intergovernmental organizations
Authors: Weyrauch David Benjamin , Steinert Christoph Valentin 
Published: June 2021

AbstractWhy do states’ human rights records converge with co-members in intergovernmental organizations (IGOs)? This study provides new insights on whether interactions in IGOs have the capacity to genuinely transform state preferences or whether norm diffusion is a consequence of instrumental processes. We leverage information about the timing of human rights alignment to disentangle intrinsic from instrumental motives. We hypothesize that instrumental motives find expression in pre-membership alignment and reversions to original normative standards after IGO exits. Intrinsic motives lead to gradual alignment during IGO membership and result in stable normative changes beyond IGO exits. Using varying-slopes, varying intercepts models, we investigate the distance on human rights indices between individual states and IGO means. While we find evidence for systematic convergence during IGO membership, no significant changes occur before and after IGO membership. Testing alignment of different physical integrity rights, we find no evidence for instrumental shifts to clandestine repression during IGO membership. Overall, the results suggest that norm alignment in IGOs is at least not exclusively instrumentally motivated. Our findings support constructivist arguments on state interests and suggest that IGOs are capable of transforming states’ human rights related preferences.
The Functional and Allometric Implications of Hipbone Trabecular Microarchitecture in a Sample of Eutherian and Metatherian Mammals
Authors: Webb Nicole M. 
Published: June 2021

AbstractThe pelvis plays an active role in weight bearing and countering the ground reaction forces incurred by the hindlimbs thus making it a critical component of the locomotor skeleton. Accordingly, this anatomical region is theoretically ideal for inferring locomotor behavior from both external skeletal morphology and trabecular microarchitecture, with the latter possibly offering nuanced insights into the mechanical loading environment given its increased plasticity and higher turnover rate. However, trabecular microarchitecture is also known to be influenced by a variety of factors including body size, sex, age, genetic regulation, diet and activity level, that collectively hinder the ability to generate consistent functional inferences. In this study, a comparative sample of mammals (42 species spanning four orders) of varying sizes, yet comparable locomotor repertoires, were evaluated to determine the effects of body size, phylogeny and locomotion on hipbone trabecular microarchitecture. This study found a weak functional signal detected in differences in bone volume fraction and the degree of anisotropy across certain pre-assigned locomotor categories, while confirming previously recognized allometric scaling trends reported for other mammalian samples based on the femur. Within primates, a more anisotropic pattern was observed for quadrupedal species attributed to their repetitive loading regimes and stereotypical limb excursions, while isotropic values were revealed for taxa utilizing more varied arboreal repertoires. Humans, despite a frequent and predictable loading environment associated with their use of bipedalism, showed relatively isotropic values. This study highlights the confounding factors that influence trabecular microarchitecture and consequently limit its utility as a method for investigating locomotor adaptation.

AbstractThe proposed spectral control of the adaptive metabolic responses to drought was tested by the comparison of two wheat genotypes with different stress tolerance. White light was used as the reference to see the effects of the three altered ratios of blue, red, and far-red spectral components, which conditions are referred to as blue, pink, and far-red lights. Under all spectral conditions, drought greatly reduced the growth of both genotypes. However, the glutathione content decreased and the proline level increased, independently of the spectrum, only in the sensitive genotype. Far-red light greatly decreased the amount of cystine and glutathione disulphide during the stress which resulted in their lower ratios compared to the reduced forms only in the tolerant genotype. The maintained more reducing redox environment contributes to its better stress tolerance. In far-red light, drought induced a greater accumulation of several free amino acids (mHis, Val, Ile, Leu, Asn, His, Tyr, Lys, Arg) in the tolerant genotype, while a smaller one in the sensitive genotype compared to the other spectral conditions. The transcript level of the genes related to amino acid and glutathione metabolism was also different between the two genotypes under this condition. The present results indicate the adaptive adjustment of glutathione and amino acid levels by far-red light during drought which observation can serve as a basis for the spectrum-dependent modification of the protective metabolites (glutathione, proline) of crops to reduce the stress-induced damages.
Use of Protection for Unwanted Pregnancy and Sexually Transmitted Infections in Six Birth Cohorts in Norway 2020: A Descriptive Study
Authors: Træen Bente , Fischer Nantje 
Published: June 2021

AbstractThis study describes the use of contraception and protection for sexually transmitted infections (STIs) in six different birth cohorts of the general population in Norway. The results are based on a 2020 national web panel survey among 18–89 year-olds in Norway (n = 4160). For respondents born within 1931–1950 versus those born within 1990–2002, there was a significant increase in the use of protection against unwanted pregnancy and STIs during sexual intercourse, and a significant drop in the proportion of those who did not use any protection at all. More women today (than in previous decades) are using hormonal contraception. The main reason for not using condoms during intercourse was both parties felt safe that they were healthy, especially those born within 1990–2002. To prevent unwanted pregnancy and STIs, it is beneficial to continue to increase the availability of free or subsidized hormonal contraception, including emergency contraception, and free condoms in public arenas that people frequent and where they meet their partners.
High avoidance and low approach motivation affect cognitive reappraisal generation in the face of anger

Published: June 2021

AbstractThis study investigates the link between the revised reinforcement sensitivity theory (RST) and individuals’ capacity to spontaneously invent alternate appraisals for aversive events. Eighty-two women completed the Reappraisal Inventiveness Test for anger-eliciting situations, and quantity and quality of reappraisal ideas were correlated with BIS, BAS, and FFFS sensitivity (RST-Personality Questionnaire). Results revealed that high BIS and high FFFS reduced the total number of reappraisal ideas, indicating that combined heightened sensitivity of the two avoidance systems may deplete individuals’ repertoire of potential reappraisals. RST effects on the quality of generated reappraisals were also found. High BIS and low BAS lowered individuals’ propensity to produce positive re-interpretations, which are considered a more adaptive reappraisal tactic. High FFFS sensitivity was linked to a lower preference for problem-oriented reappraisals. This study underlines that certain interactions of motivational subsystems may be particularly detrimental for successful reappraisal of anger-eliciting events. Our findings reveal potential links between revised RST effects and adaptive emotion regulation.
Empirical rock physics relationships on carbonate dry-frame elastic properties

Published: June 2021

AbstractLaboratory tests were conducted to analyze the ultrasonic velocity response to the pressure change in dry carbonate rocks from the Weyburn oilfield, Canada. Twenty-four samples are from seven wells with helium porosities ranging from 1% to 29%. Thin-section images, SEM and mercury intrusion porosimetry were performed to show their inner structures and pore throat size distributions. P- and S-wave velocities (Vp and Vs) measurements were first done under hydrostatic loading and then while unloading, with confining pressures varying between 3 and 35 MPa. The results indicate that Vp and Vs in these samples follow a linear relation independent of the pressure change. The ratio Vp/Vs is more responsive to pressure change irrespective of the pore volume. One-third of the carbonate samples show abnormal Vp/Vs reduction with the increase in the effective pressure. The pressure dependence of velocities (PDV) of Weyburn carbonate rocks varies widely even for samples from the same formation with similar sedimentary history. Samples with loosely packed crystals and/or relatively large dominant pore diameter have higher PDV. The exponential empirical model V = $$A-C\text{e}^{DP_{\text{e}}}$$

The model gives good fits for most of the Weyburn carbonate samples. From a statistical point of view, there is no difference between the Vp- and Vs-derived exponential coefficient D.
Deoxygenation impacts on Baltic Sea cod: Dramatic declines in ecosystem services of an iconic keystone predator
Authors: Orio Alessandro , Heimbrand Yvette , Limburg Karin 
Published: June 2021

AbstractThe intensified expansion of the Baltic Sea’s hypoxic zone has been proposed as one reason for the current poor status of cod (Gadus morhua) in the Baltic Sea, with repercussions throughout the food web and on ecosystem services. We examined the links between increased hypoxic areas and the decline in maximum length of Baltic cod, a demographic proxy for services generation. We analysed the effect of different predictors on maximum length of Baltic cod during 1978–2014 using a generalized additive model. The extent of minimally suitable areas for cod (oxygen concentration ≥ 1 ml l−1) is the most important predictor of decreased cod maximum length. We also show, with simulations, the potential for Baltic cod to increase its maximum length if hypoxic areal extent is reduced to levels comparable to the beginning of the 1990s. We discuss our findings in relation to ecosystem services affected by the decrease of cod maximum length.
NO2-immission assessment for an urban hot-spot by modelling the emission–immission interaction
Authors: Steinhaus Tim , Thiem Mikula , Beidl Christian 
Published: June 2021

AbstractUrban air quality and climate protection are two major challenges for future mobility systems. Despite the steady reduction of pollutant emissions from vehicles over past decades, local immission load within cities partially still reaches heights, which are considered potentially hazardous to human health. Although traffic-related emissions account for a major part of the overall urban pollution, modelling the exact interaction remains challenging. At the same time, even lower vehicle emissions can be achieved by using synthetic fuels and the latest exhaust gas cleaning technologies. In the paper at hand, a neural network modelling approach for traffic-induced immission load is presented. On this basis, a categorization of vehicle concepts regarding their immission contribution within an impact scale is proposed. Furthermore, changes in the immission load as a result of different fleet compositions and emission factors are analysed within different scenarios. A final comparison is made as to which modification measures in the vehicle fleet offer the greatest potential for overall cleaner air.
Identity Expression—the Case of ‘Sakawa’ Boys in Ghana
Authors: Alhassan Abdul-Razak Kuyini , Ridwan Abukari 
Published: June 2021

AbstractInternet fraud remains a problem in Ghana and thus attracts the attention of teachers, researchers, civil society organisations, the state and policymakers. Existing studies on Internet fraud focused on the reasons, combat strategies, cyber spiritualism, the impact of Internet fraud on individuals and the country, and the inadequate legal frameworks for handling such cybercrimes. Despite efforts by the government and other interest groups in fighting the menace, the phenomenon continues to increase among youth in Ghana. Applying Paul Willis’ theory of ethnographic imagination, this study examined how Internet scammers—Sakawa boys—in the northern region of Ghana use their bodies and other cultural materials to express their identity and make meaning. The study reveals that Sakawa boys express their identities and make meaning using language—slang and jargon; conspicuous consumption of material goods; ostentatious lifestyle; techno-religiosity; and gender cyber-fraud collaboration. Thus, it offers a basal understanding of emic dimension of relationship between children and youth in cybercrime, unsuspected victims, and preventive measures. The study also gives theoretical contributions to research in understanding the broader socio-cultural milieu of children and youth in crimes and possible practical measures towards containment.
Ion-Exchange Modeling of Divalent Cation Adsorption on SWy-3 Montmorillonite
Authors: Li Yayu W. , Schulthess Cristian P. 
Published: June 2021

AbstractIon-exchange modeling is used widely to describe and predict ion-adsorption data on clay minerals. Although the model parameters are usually optimized by curve fitting experimental data, this approach does not confirm the identity of the adsorption sites. The purpose of the present study was to extend to divalent cations a previous study on the retention of monovalent cations on Na-saturated montmorillonite (NaMnt) which optimized some of the model parameters using density functional theory (DFT) simulations. The adsorption strength of divalent cations increased in the order Mg2+ < Cd2+ < Ca2+ < Sr2+ < Ba2+. After adding adsorption of metal hydroxide species (MOH+), the three-site ion-exchange model was able to describe adsorption data over a wide pH range (pH 1–10) on NaMnt. X-ray diffraction (XRD) analyses were conducted to investigate the interlayer dimension of clay samples under various conditions. The cation retention strengths of divalent cations did not correlate with interlayer dimensions. The XRD analyses of the Mnt showed a d001 value of 19.6 Å when saturated with alkaline earth cations, 22.1 Å with Cd2+, 15.6 Å with Na+, and 15.2 Å with H+. In the case of Na+, the 15.6 Å peak decreased gradually and disappeared, and new peaks at 22.1 and 19.6 Å appeared when the percentages of Mg2+ and Ba2+ adsorbed increased on NaMnt. The peak shifted from 22.1 to 20.3 and 19.6 Å when the pH increased for all cations except Cd2+, which stayed constant at 22.1 Å. The coexistence of multiple d001 peaks in the XRD patterns suggested that the interlayer cations were segregated, and that the interlayer ion–ion interactions among different types of ions were minimized.
On the thickness of the Antarctic ice, and its relations to that of the glacial epoch
Authors: CROLL James , SUGDEN David 
Published: June 2021

ABSTRACTAt a time when nobody has yet landed on the Antarctic continent (1879), this presentation and accompanying paper predicts the morphology, dynamics and thermal regime of the Antarctic ice sheet. Mathematical modelling of the ice sheet is based on the assumptions that the thickness of tabular icebergs reflects the average thickness of the ice at the margin and that the surface gradients are comparable to those of reconstructed former ice sheets in the Northern Hemisphere. The modelling shows that (a) ice is thickest near the centre at the South Pole and thins towards the margin; (b) the thickness at the pole is independent of the amount of snowfall at that place; and (c) the mean velocity at the margin, assuming a mean annual snowfall of two inches per year, is 400–500 feet per year. The thermal regime of the ice sheet is influenced by three heat sources – namely, the bed, the internal friction of ice flow and the atmosphere. The latter is the most significant and, since ice has a downwards as well as horizontal motion, this carries cold ice down into the ice sheet. Since the temperature at which ice melts is lowered by pressure at a rate of 0.0137 °F for every atmosphere of pressure (something known since 1784), much of the ice sheet and its base must be below the freezing point. Estimates of the thickness of ice at the centre depend closely on the surface gradients assumed and range between 3 and 24 miles. Such uncertainty is of concern since both the volume and gravitational attraction of the ice mass have an effect on global sea level. In order to improve our estimate of the volume of ice, we will have to wait 76 years for John Glen to develop a realistic flow law for ice.
The ‘janitor-geologist’ and the ‘cold materialistic scientific men’: James Croll's navigation of scientific societies
Authors: BRASSINGTON Laura 
Published: June 2021

ABSTRACTScientific societies played a crucial role in the emergence of a professional culture of science in Britain in the mid- to late-19th Century. At first sight, James Croll's membership of a limited number of scientific associations may be assumed to be the result of his lack of social credit and scientific connections. In this article, by examining Croll's correspondence, I demonstrate that Croll's select participation in scientific clubs and associations reflected his strategic pursuit of a vision of science set apart from party or societal affiliation. I focus on the contrasting histories of the Royal Society of Edinburgh and the Geological Survey, as well as the institutional history of thePhilosophical Magazine. Situating the institutions in their respective social and cultural contexts, I argue that the more meritocratic, inclusive social structure of the Survey andMagazinehelps explain Croll's choice to avoid affiliation with the Royal Society of Edinburgh.
James Croll, celestial mechanics and climate change
Authors: LONGAIR Malcolm 
Published: June 2021

ABSTRACTJames Croll was a pioneer in studies of the impact of the slowly changing orbital dynamics of the Earth on climate change. His book Climate and Time in their Geological Relations (1875) was far ahead of its time in seeking correlations between climate change, the occurrence of ice ages and perturbations to the Earth's orbit about the Sun. The astronomical cycles he discovered are now called ‘Milankovitch Cycles’ after the Serbian scientist whose research was first published in the Handbuch der Klimatologie in 1930. The celestial mechanical and astronomical background to Croll's research is the focus of this essay. The development of the understanding of the impact of perturbations of the elliptical planetary orbits by other bodies in the solar system paralleled new mathematical techniques, many of which were developed in association with celestial mechanical problems. The central contributions of many of the major mathematicians of the late 18th and 19th Centuries, including Euler, Lagrange, Laplace and Le Verrier, are highlighted. Although Croll's contributions faded from view for several generations, his pioneering insights have now been demonstrated to have been basically correct.
James Croll and geological archives: testing astronomical theories of ice ages
Authors: TZEDAKIS Polychronis C. , WOLFF Eric W. 
Published: June 2021

ABSTRACTJames Croll's Physical Theory of Secular Changes of Climate emerged during an age of revolution in geology that included the rise of the glacial theory and the search for its underlying causes. According to Croll, periods of high eccentricity are associated with the persistence of long glacial epochs, within which glaciations occur in alternate hemispheres when winter is at aphelion every ~11,000 years; however, astronomical forcing is only able to produce glaciation by means of physical agencies (climate feedbacks) that amplify the small effects of varying seasonal irradiation. Croll understood the importance of interglacial deposits because they provided evidence for the occurrence of multiple glaciations within his long glacial epochs. He was aware of the limitations of the terrestrial record and suggested that deep-sea sediments would contain a continuous succession of glacial-interglacial cycles. Contrary to a widespread view, however, Croll was not envisaging the advent of palaeoceanographic exploration avant la lettre, but instead was drawing attention to the inadequacy of the land record as a testbed of his astronomical theory. Yet, the marine record did eventually deliver a test of astronomical theories almost exactly 100 years after the publication of his 1875 book Climate and Time in their Geological Relations. Here, we provide an historical account of the technological and scientific developments that led to this and a summary of insights on astronomically paced climate changes from marine, terrestrial and ice core records. We finally assess Croll's ideas in the context of our current understanding of the theory of ice ages.
Le mouvement social en 1933
Authors: Velge Henri 
Published: June 2021

Lévolution de la législation sociale pendant l’année 1933 se caractérise spécialement par l’introduction de dispositions nouvelles inspirées par la situation financière.Le déficit croissant a nécessité, dans le courant de cette année, l’adoption d’une série de mesures importantes : une grande place est occupée, parmi celles-ci, par les réformes rendues nécessaires par les abus constatés dans l’application de certaines lois sociales.Déjà en 1932, certaines modifications que nous avons signalées l’année dernière (1) avaient été adoptées. Nous annoncions à ce moment qu’il ne s’agissait que d’un début, et que la révision de certains textes législatifs ou réglementaires devrait être poursuivie en 1933. Cette poursuite s’est faite énergiquement, grâce aux pouvoirs spéciaux accordés au gouvernement par la loi du 17 mai 1933.
Le chômage en 1933
Authors: Baudhuin Fernand 
Published: June 2021

Le problème du chômage demeure un des plus préoccupants de l’heure. Il continue à requérir l’attention des économistes et celle des pouvoirs publics. On ne s’étonnera donc pas que nous lui accordions encore une place importante dans le présent annuaire. Ceci bien que, à notre avis, la Belgique n’ait pas été jusqu’ici un pays où la main-d’œuvre soit en excès d’une façon permanente, et bien qu’elle ait souffert du chômage dans une mesure moindre que la plupart des autres nations industrielles.Rappelons que la Belgique ressentit les premières manifestations de la crise vers juillet 1929, et surtout en novembre, quand le marché diamantaire d’Anvers fut atteint par les conséquences du krach de Wall Street. Le chômage ne fit son apparition qu’au printemps de 1930, et il demeura bénin jusqu’en 1931. Survint alors la chute de la livre sterling, dont les conséquences furent redoutables. Certes, le pays ne fut-il pas touché dans ses œuvres vives, mais le chômage s’aggrava sérieusement durant toute l’année 1932.
