Published: February 2023

In this paper, the covalent organic polymer of enaminone was modified by thiourea, and the covalent organic polymer of thiourea (CTOP) was synthesized by simple solvothermal method. At 25 ℃, the adsorption capacity of the polymer for trivalent gold ion is 2372.7 mg/g. In the mixed aqueous solution of divalent cadmium ion, trivalent gold ion, divalent copper ion, divalent cobalt ion and divalent nickel ion, CTOP can only adsorb trivalent gold ion, which indicates that CTOP has high selective adsorption performance for trivalent gold ion. In addition, CTOP material still maintains high adsorption performance after five adsorption cycles, which proves that the adsorption material has good reusability. According to the experimental results of adsorption kinetics and thermodynamics, the adsorption process of CTOP for trivalent gold ions conforms to the quasi second order adsorption model and Langmuir adsorption model, that is, the adsorption process of CTOP for trivalent gold ions is single-layer chemical adsorption. CTOP not only has strong adsorption and selectivity to Au (Ⅲ), but also has good reusability. Therefore, it is an ideal environmental functional material, which can be used to separate and enrich trivalent gold ions in wastewater.

Structure and composition of small mammal assemblages are excellent indicators of habitat quality and often used to study impacts of perturbations such as wildfires on faunal communities. One of the most efficient and widely used tools for assessing small mammalian assemblages are hair-tubes. Despite their efficiency, they are often damaged by non-target species such as wild boar (Sus scrofa). However, the impact of such damage on the use of hair-tubes has apparently never been formally assessed. In this study, wildlife-induced disturbance of hair-tube sampling was quantified in the mountain chain of Monte Pisano (Italy), a fire-prone area. At each site, two hair-tubes were tied together to form a “pan-pipe” and placed in three repetitions. Disturbances were measured, including camera-traps to identify damaging species.
Although approximately 27% (N=164/600) of pan-pipes were disturbed, two pan-pipes per site resulted in 96.5% undisturbed pan-pipes. Unexpectedly, as the most frequently disturbed pan-pipes were those monitored by camera-traps, our rates were considered overestimates. Perhaps this was due to attraction of the wild boars, by means of olfactory/acoustic signals. Boar was the wild species with the greatest impact on pan-pipes, and its impact and rates of all wildlife disturbances did not differ among habitats. Furthermore, displaced tubes were not significantly different from undisturbed tubes in terms of numbers of hairs collected and biodiversity estimates.
To avoid data loss when conducting pan-pipe monitoring, we suggest using at least two pan-pipes per site. Finally, displaced tubes that are retrieved should provide reliable data.
Oil-in-water Pickering emulsions stabilized by nanostructured cellulose: comparison of cellulose nanocrystals and nanofibrils

Published: February 2023

Nanostructured celluloses, in the form of nanofibrils (CNFs) and nanocrystals (CNCs), obtained through TEMPO-mediated oxidation, by controlling the intensity of the process (changing catalyst concentration and processing time), were tested in the stabilization of Pickering emulsions, fabricated through high-pressure homogenization (HPH). Results showed that both CNFs and CNCs provided an efficient steric and electrostatic stabilization of the oil-in-water emulsions. Remarkably, the strong inter-droplet interactions, observed when CNFs were used as stabilizers, because of fibrils entanglement in the continuous phase, resulted in a 3D fibrous network emulsion, with higher viscosity than CNCs-stabilized emulsions, and higher tendency towards flocculation. However, the HPH treatment significantly affected the nanofibrils interfacial layer, promoting the emulsifying ability of CNFs, and increasing stability against coalescence. In contrast, CNCs-stabilized emulsions exhibited, along with lower viscosity, higher interfacial activity and emulsion stabilization capability, without any phase separation during 10 months of refrigerated storage. Remarkably, the HPH treatment did not significantly change the emulsifying ability of CNCs. Therefore, it can be concluded that nanocelluloses with tailored emulsifying properties can be easily obtained through the regulation of the process intensity of TEMPO-mediated oxidation of pulp cellulose, opening the way to the production of new ingredients for the food and cosmetic industries.

Published: February 2023

This study evaluated the effects of extracts prepared using two different methods (decoction extraction and, Soxhlet ethyl acetate/hexane extraction) from Inula viscosa on H2O2-induced oxidative stress and wound healing model in mouse L929 fibroblast cells. The cytotoxic effect started to disappear statistically (p < 0.05) at concentrations of Soxhlet ethyl acetate/hexane extracts (SoxEHEs) in and below 0.1 mg/mL, while the same effect was observed at concentrations of decoction extracts (DEs) in and below 0.2 mg/mL. Therefore, 0.2 and 0.02 mg/mL concentrations of DE, and 0.1 and 0.01 mg/mL concentrations of SoxEHEs were used. While cell migration was positively affected in all concentrations of the research, statistically significant results (p < 0.05) were obtained from 0.2 mg/mL of DE and 0.1 mg/mL of SoxEHE extracts. Malondialdehyde (MDA) levels were found to be statistically (p < 0.05) decreased, but COL1A1 levels were higher in cell lines treated with oxidative stress + extract than in the cell line treated only with H2O2, and reduced glutathione (GSH) levels were higher in cell lines only treated only with extract than in oxidative stress-induced cell lines. Consequently, it has been observed that the extracts have positive effects on migration and oxidative stress. Therefore, I. viscosa may serve as a new therapeutic agent for wound healing.
Lattice Boltzmann high-performance simulations of decaying isotropic turbulence
Authors: Kareem Waleed Abdel , Mohammed Hadeer , Sherbiny Hamed El , Asker Zafer
Published: February 2023

This study investigates high-performance computing (HPC) strategies for improving and reducing the time consumption of the simulations of turbulent flows in periodic boxes at different resolutions using the lattice Boltzmann method (LBM). Isotropic turbulence is a fundamental problem in fluid dynamics that can be considered a good candidate for examining HPC applications. The LBM is a computational method that can be computationally parallelized, hence proper parallelization and vectorization are provided for reducing data volume and data transfer. Simulations of decaying isotropic turbulence at resolutions starting from 323 to 5123 using the LBM are carried out for these purposes. Clear progress for time reduction is achieved in all cases, while different features of the flow fields are depicted, and their characteristics are discussed. Very thin tubes are visualized, and the energy spectra are studied. More than 88%-time reduction is obtained in favor of the HPC using the same hardware resources with the lattice Boltzmann relaxation time 𝝉 = 0.503. All fields are initialized by a forced turbulent field that was simulated in a previous study using the LBM.

A series of poly (vinyl chloride) (PVC) composites have been madethrough an in-situ suspension polymerization process in attendanceof 5 wt% of MgAl(NO3) layered double hydroxide (LDH) or 3-(trimethoxysilyl) propyl methacrylate (MPTMS)-intercalated Mg-AlLDH (MPTMS-LDH). The thermal stability and mechanical and phys-ical properties of the prepared composite samples were examined andcompared with the pure PVC. The data obtained from the Brabender®plastograph illustrated that the final PVC grains prepared in atten-dance of MPTMS-LDH have higher thermal stability time and lowerfusion. The fusion degree of PVC particles has been incremented byMPTMS-LDH nanosheet; as a result, it has been observed that alower requirement of temperature/time process. A conventional dehy-drochlorination test proved the improvement of thermal stability. The composite, including MPTMS-LDH, showed a 40% improvement indehydrochlorination rate relative to the pure PVC, this enhance-ment is 12% in comparison with PVC/LDH composite. TGA curvesshow that the 5 and 50% weight loss temperatures of PVC resinshave remarkable growth (∼11 ◦C) with introducing 5 wt% LDH orMPTMS-LDH. The storage modulus of the glassy state(glassy plato)and the Tg of the PVC/MPTMS-LDH is higher than the pure PVCand composite of PVC/LDH. The results of mechanical analysis illus-trated that PVC/LDH-MPTMS composites have larger stiffness andtoughness. The Charpy notched impact strength, tensile strength, andYoung’s modulus of the PVC/LDH-MPTMS composites are signifi-cantly more than the composite of PVC/LDH and the pure PVC.

Authors: Sun Weifeng , Chang Kangkang , Zhang Bowei
Published: February 2023

There are many relational data in edge computing They belong tonon-Euclidean spatial data. Graphical neural network can expand edgecomputing capabilities to extract features from non-Euclidean spatialdata, and thus is suitable for edge computing data classification and filtering. In IoT edge computing, there are many computing nodes anddata to be transmitted. Therefore, how to transmit the most needed datato the computing nodes is an important issue, and a better recommendation model is needed to filter t he e dge d ata. L ightGCN i s a superiorrecommendation model based on graph neural network, but there is stilla problem of over-smoothing when the user-item relationship extractionlayer is stacked with multiple layers. To solve this problem, this paperproposes an improved graph neural network collaborative filtering algorithm for edge computing (ECCF) to build a deeper graph neural networkto achieve better feature extraction, keep the purity of local features,and improve recommendation performance. ECCF uses hard negativemining method as a sampling method to improve recommendation accuracy and training efficiency, and uses IndRNN with long and short-termmemory with self-attention layer to capture valid information.The experimental results of the model using Gowalla, Yelp 2018 and AmazonBook show that ECCF performs better in NDCG and Recall evaluationmetrics than LightGCN, IMP-GCN and NGCF. ECCF improves the recommendation accuracy while minimizing the complexity of the model,which is well adapted to be applied to data filtering for edge computing.
Kidney-eye metabolomics in a mouse mode of oxygen-induced retinopathy correlates with those in retinopathy of prematurity
Authors: Yang Yuhang , Dong Lijun , Qi Hui , Zhang Yinsheng , Lu Xiaofeng , Fan Zixin , Wu Dongting , Zhang Guoming , Lei Hetian
Published: February 2023

Background：Retinopathy of prematurity (ROP) is one of the leading causes of babies’ visual impairment and blindness. There is no effective intervention with ROP so far, and thus a deeper understanding of oxygen-induced metabolism may offer novel potential therapeutic approaches to ROP. The aim of this study is to explore a correlation of oxygen-induced renal metabolism with those in eyes and blood from ROP patients or a mouse model of oxygen-induced retinopathy (OIR).
Methods：At postnatal day 7 (P7), 30 healthy C57BL6/J mice were randomly selected and divided into two groups, an OIR group and a WT group. The R-OIR group (N = 8) and R-WT group (N = 8) were examined for renal untargeted metabolomics; Targeted metabolomics analysis was performed to detect vitreous in V-OIR group (N = 7) and V-WT group (N = 7). Network association analysis was performed with the above results and previous studies: retinal-targeted metabolomics of OIR and human blood-targeted metabolomics of ROP.
Results：The levels of metabolites in the R-OIR group were slightly higher than those in the R-WT group, especially in lipids. However, nucleotides of the R-OIR group were lower than the R-WT group. There were 9 canonical signaling pathways enriched, in which the initiation and progression of pathologic retinal neovascularization were closely associated with purine metabolism, arginine biosynthesis, histidine metabolism, pantothenate and CoA biosynthesis, alanine, aspartate and glutamate metabolism; arginine and proline metabolism, tryptophan metabolism, beta-Alanine metabolism, and D-glutamine as well as D-glutamate metabolism. In addition, L-histidinol, Isoguanosine, guanosine, guanine, nicotyrine, quinoxaline-2-carboxylic acid, L-3-hydroxykynurenine, N-gamma-glutamyl-S-propylcysteine, alanine, adenosine diphosphate, and ribose were potential biomarkers of ROP.
Conclusion：Shikimic acid and PC(14:1(9Z)/20:2(11Z,14Z)) are highly specific biomarkers of renal metabolomics of OIR. Arginine biosynthesis is the best common pathway of kidney-untargeted OIR metabolomics, vitreous-, and retina-targeted OIR metabolomics, and blood-targeted metabolomics of ROP, indicating that arginine biosynthesis is the common pathway of ROP and neonatal kidney injury.

Published: February 2023

Aquatic mesocosms are complex test systems used within regulatory risk assessment of plant protection products. These model ecosystems allow to capture interactions of multiple species under environmental conditions. They enable assessment of direct and indirect effects of stressors at all trophic levels and impacts on ecosystem functions. Due to the limited ability to test the multitude of potential exposure scenarios, cross-linking aquatic mesocosm studies with virtual mesocosms, i.e. aquatic system models (ASMs), can serve to meet the demand for more environmental realism and ecological relevance in risk assessment. In this study, full control data sets from seven aquatic mesocosm studies conducted at a single test facility under GLP are graphically analysed. Thereby, not only a comprehensive data base but also an insight into the species present, their dynamics over time and variability in unchallenged mesocosms is provided. While consistency in dynamics could be discerned for physical and chemical parameters, variability was evident for several biological endpoints. This variability points to amplification of small differences over time as well as to stochastic processes. The outline of existing gaps and uncertainties in data leads to the estimation of what can be expected to be captured and predicted by ASMs.
Teaching Thematic Structure in Greek through Design-Based Research
Authors: Malmen Evangelos
Published: February 2023

In the ESL/EFL bibliography it is suggested that teaching topical structure analysis helps students improve coherence in writing. This paper aims at presenting an integrated thematic structure teaching model for Greek secondary education and arguing for its impact on student argumentative text writing in terms of cohesion and coherence. The research methodology followed was design-based, involving four pre- and four post-tests student writing samples, field notes derived mainly from three non-participant observers and the teacher-researcher, and four focus group student interviews, along with two observer interviews. The findings indicate that student writing significantly improved following this intervention. In addition, student post-test performance was closely related to the explicit and systematic teaching of thematic structure. These results suggest that the new model can further be used in developing the writing skills of secondary education students.

Published: February 2023

In modern society, there is a constant development and improvement of the transport industry, due to which the role and distribution of this logistics industry, which is a service, is growing for the high-quality and fast delivery of goods. To maximize the export of finished products and more effective penetration into international markets around the world are organized by global logistics systems. This article summarizes the arguments and counterarguments within the scientific discussion on the place and prospects of management of the transport infrastructure of global logistics. The study’s main purpose is to confirm the hypothesis about the existence of global logistics clusters united by a common transport infrastructure in accordance with the geopolitical and economic features of the regions. In this regard, the array of input data is presented in the form of ten transport infrastructure indicators from databases of the World Bank and Organisation for Economic Co-operation and Development. The study of the transport infrastructure of global logistics in the article is carried out in the following logical sequence: the formation of an array of input data; input data normalization; determination of the integral index of the level of transport infrastructure’s development (principal component method); clustering (the k-means method) and interpretation of the obtained results. Forty-five European and Asian countries were selected as the object of the study from 2006 to 2020. The study empirically confirms the above hypothesis, evidenced by the identified integral index of the level of transport infrastructure’s development and qualitative composition of the obtained clusters. The road passenger transport indicator exerts the most significant influence on the integral index of transport infrastructure, air transport, passengers carried, container port traffic and railways, passengers carried. In general, during the studied period, countries were grouped into three and two clusters. The consolidation of clusters in 2020 indicates that the transport infrastructure of countries with an average level of economic development began to develop actively. In particular, this concerns the increased demand for road transport. The study results can be useful for public authorities and international organizations that provide services for managing the transport infrastructure of global logistics.

Published: February 2023

:

Nutritionally variant streptococci (NVS) were assumed to be nutritional mutants of
the viridans group of streptococci, but they are now considered as other Streptococcus species.
Due to their difficult nature, to date, the detection and treatment of NVS are challenging.

:

This review aims at a compilation of a comprehensive study on literature reporting the
microbiological characteristics of NVS species, their detection, and treatment strategies with an
emphasis on large-scale research experimentations.

:

According to the literature, the classification of these Streptococci has changed several times,
interpreting the scientific literature of Abiotrophia and Granulicatella spp. NVS strains exhibit
pleomorphic cellular morphologies, and they can be distinguished from other streptococci by
their biochemical reactions and molecular tests. They have been isolated from clinical specimens
including pus, synovial fluid, and blood, in addition to their involvement in endocarditis.
Treatment of NVS is challenging due to its difficult nature and the complexity of antimicrobial
susceptibility testing.

:

Early diagnosis is critical for initiating proper therapy and avoiding fatal consequences.
Microbiologists and clinicians ought to be cautious of these isolates, which are easy to overlook
due to their difficult nature and the challenges in retrieving from clinical samples. Hence largescale
research is required to identify additional detection techniques, infrastructure, and
treatment options.

Jamu is a pharmaceutical preparation derived from plant simplicia and must meet quality requirements, one of which is that it must not contain medicinal chemicals (BKO). One of the herbs widely circulated and can be obtained freely in the community is herbal medicine for aches and pains. In herbal aches and pains, paracetamol is the BKO suspected to be used in this preparation. This study aimed to develop an analytical method to determine the content of paracetamol BKO in herbal pain relief semi-quantitatively using digital images obtained from Thin Layer Chromatography. The semi-quantitative analysis method is carried out by processing digital images using the qTLC application. The results of this study proved the presence of paracetamol BKO in herbal aches and pains qualitatively using the TLC method. Of the five samples analyzed, only one contained paracetamol BKO with an Rf value of 0.15, while the standard Rf was 0.14. The analysis was then continued with the determination of paracetamol levels semi-quantitatively using digital image processing from the Thin Layer Chromatography results. Based on the results of semi-quantitative analysis, it can be seen that the sample suspected to contain paracetamol contains paracetamol with a concentration of 1,491.31 ppm. The results of this study can provide accurate detection of paracetamol BKO compound determination and semi-quantification limits and have the potential for more quantitative analysis in herbal medicine.
Postawy pielęgniarek wobec nieskutecznej reanimacji z powodu nagłego zatrzymania krążenia
Authors: Pokorniecka Daria
Published: February 2023

Wstęp.  Nagłe zatrzymanie krążenia to według definicji nieoczekiwane ustanie funkcji serca. Cechami charakterystycznymi są: brak reakcji na bodźce, brak wyczuwalnego tętna i bezdech bądź oddech agonalny. Niektóre źródła, za NZK, uznają również znaczne upośledzenie pracy serca. Kluczowe znaczenie w przypadku tego poważnego problemu medycznego ma natychmiastowa i odpowiednia pomoc.

Cel. Głównym celem pracy jest analiza postaw personelu pielęgniarskiego wobec nieskutecznej reanimacji.

Materiał i metody. Przedmiotem badań są postawy pielęgniarek wobec nieskutecznej reanimacji z powodu nagłego zatrzymania krążenia. Dla potrzeb pracy skorzystano z metody sondażu diagnostycznego, autorskiego kwestionariusza ankiety, standaryzowanego kwestionariusza Mini COPE oraz metod statystycznych.

Wyniki. Analiza zebranych danych dała wyniki ukazujące postawy wobec nieskutecznej reanimacji. Nie potwierdzono istotnej zależności pomiędzy wiekiem, stażem pracy, wykształceniem i płcią a postawą prezentowaną przez badanych. Nie potwierdzono również hipotezy o najczęstszym występowaniu postawy poszukiwania wsparcia w sytuacji stresowej jaką jest nieskuteczna reanimacja. W badaniu strategia aktywnego radzenia sobie i akceptacji była dominująca.

Wnioski. Spośród wszystkich postaw reprezentowanych przez personel pielęgniarski wobec nieskutecznej reanimacji dominującą była postawa aktywnego radzenia sobie. Ponieważ badania dowodzą, że wiek, wykształcenie, czy staż pracy nie wpływają istotnie na sposób radzenia sobie ze stresem wynikłym z nieskutecznej reanimacji, powstaje realna potrzeba pogłębienia zagadnienia i stworzenia narzędzi do wsparcia emocjonalnego i instrumentalnego personelu stykającego się z  problemem.

Authors: Witkowska Aleksandra
Published: February 2023

Wstęp. Niniejsza praca stanowi próbę oceny jakości życia pacjentów poddawanych hemodializie. Ta ze względu na dotkliwość oraz uporczywość choroby powoduje poważne obciążenia. W związku z tym jakość życia może być różna w zależności od zastosowanych metod leczenia, wieku, wsparcia najbliższych, ale również długości choroby.

Cel. Celem niniejszej pracy jest ocena jakości życia pacjenta dializowanego.

Materiał i metody. W pracy wykorzystano metodę sondażu diagnostycznego. W tym celu opracowano własny kwestionariusz ankiety oraz kwestionariusz SF 36. Dzięki temu do badania zaproszono 100 osób, które wskazały na własne doświadczenia z chorobą.

Wyniki. W ramach przeprowadzonych badań dowiedziono, że osoby różnie reagują na chorobę. Jest to uzależnione od wieku, ale i też od chorób współistniejących. Poza tym nie można zapomnieć, iż np. praca zawodowa oraz ilość spraw, które trzeba dostosować do warunków życia powoduje, że chorzy różnie oceniają swoje życie. Najczęściej jest to ocena średnia lub dobra.

Wnioski. Na podstawie przeprowadzonych badań dowiedziono, że osobom młodym trudniej pogodzić się z chorobą. To samo odnosi się do stanów emocjonalnych. Jedne osoby wspierane przez najbliższych lepiej poradzą sobie z chorobą, a inne gorzej. Może to być uzależnione od obowiązków, ale również od ich planów na życie. Dodatkowo wiele osób chorych to osoby w podeszłym wieku, a zatem zmagają one z licznymi chorobami towarzyszącymi. Mimo jednak wielu nowoczesnych metod leczenia życie pacjentów jest do pewnego stopnia ograniczone.

Scholars and the reframing of Europe: the complex relationship between language, race and nation during the Great War
Authors: Zantedeschi Francesca
Published: February 2023

Delegates attending the Paris Peace Conference in 1919 were given the arduous task of establishing the terms of the peace after WW1, including the criteria by which to determine the boundaries of new states emerging from the collapse of the old multinational empires. Given that U.S. President Woodrow Wilson had laid so much emphasis on the principle of ‘self determination’, language was considered by many as the best element to establish nationality in ethnically mixed territories. A legacy of the nineteenth century, the apparently straightforward identification between language and nation was nevertheless complicated by pervasive ideas about race, as the taxonomies of language and race became increasingly entangled.
By presenting selected works by two scholars – Leon Dominian, a geographer, and Antoine Meillet, a linguist –, this paper analyses the main and most widespread arguments propounded in support of the identification between language and nation during the Great War. It also explains why this principle turned out to be exceedingly problematic at the time of the redrawing the political map of Europe, and how the ambiguous relationship between language and race persisted during the early years of twentieth century.

Sub-state nationalisms in Spain during the Moroccan War and the Rif War (1909-1927)
Authors: Iglesias Amorín Alfonso
Published: February 2023

This article analyses how the Spanish colonial wars in Morocco in the early 20th Century influenced Catalan, Basque and Galician nationalisms at an absolutely key moment in their development. It assesses the aftermath of the Versailles settlement and the new claims of colonial peripheries, which coincided with the Disaster of Annual in 1921, Spain’s great defeat in Morocco, which served as a weapon against the State for sub-state nationalisms, and led to the appearance of the Rif Republic, a benchmark in the anti Spanish fight.
The article examines how the war was used to mobilize people against prevailing Spanish nationalism, the warmongering, colonialist, anti-war and anti-colonial discourses of the nationalisms in question and the positions of the main political parties and leaders. In short, it seek to measure the impact that this long and important war had on different Spanish national identities during the first decades of the 20th century.
Baltic national movements, 1986-1992. Origins, trajectories, agendas
Authors: Hackmann Jörg
Published: February 2023

The public appearance of national movements in Estonia, Latvia and Lithuania is closely connected to Gorbachev’s attempt to reform the Soviet Union through the politics of perestroika and glasnost. The evident similarities of these mass movements in their agendas and trajectories result from the parallel political history of the Baltic nations with the Soviet annexation in 1940 and the renewal of their independence in August 1991. Apart from this general framework the single movements show path dependencies, which are based on different social and cultural developments and shaped by the diverging scale of Russian-speaking immigrants during the Soviet period. In fact, after August 1991, the term ‘Baltic’ may serve only as a regional term for analytical purpose, as it does not mark an essentialist coherence within these movements.
This paper focusses on the origins and trajectories of the Baltic national movements between 1986 and 1992, when they ceased to exist as social movements after their success in restoring political independence. The origins of the ‘popular fronts’ (Rahvarinne in Estonia, Tautas fronte in Latvia) or ‘movement’ (Sąjūdis in Lithuania) are connected first with the support of perestroika, second with public historical debates about the Molotov-Ribbentrop-Pact and Stalinist repressions, and third with the restoration of national symbols of the pre-war republics. Music performances and festivals, and in particular the ‘Baltic chain’ on 23 August 1989 mobilized large parts of the population of the three then Soviet republics and shaped the image of the peaceful ‘singing revolution’.
Since spring 1990 divisions appeared within the independence movements between the rather reform-oriented popular movements and more radical nationalist groups striving for immediate full independence and the restoration of the pre-war nation states. These cleavages deepened after the restoration of national independence in August 1991, first of all on issues of legal restoration, language laws and de-Sovietization and largely shaped political debates in the three Baltic states in the following decades.
State of Nationalism (SoN): Nationalism and Gender
Authors: Knight Lora
Published: February 2023

Until the 1970s, nationalism studies were almost exclusively about men: male intellectuals and politicians who defined the nation for the public, and male revolutionaries or soldiers who attained and protected the nation, often claiming full political citizenship in return for their services. However, the fact of their gender and the connection between national and masculine identities was hardly acknowledged, much less interrogated until the 1980s. Ironically, seeing men as men was largely the result of asking where the women were.

The ‘Dogma of the Independence of Nations’: Nationality as the Basis of the 1919 International Legal Order
Authors: Zantedeschi Francesca
Published: February 2023

In 1851, in his famous lecture Della nazionalità come fondamento del diritto delle genti, the Italian jurist Pasquale Stanislao Mancini (1817-1888) formulated the so-called ‘dogma of the Independence of Nations’ – a fundamental principle of the political ideologies of the Risorgimento. In it, he defined nationality as ‘a natural society of individuals’ based on ‘unity of territory, origins, habits and language, and conformed to a commonality of life and social conscience.’ Although he is well known among scholars of international law, Mancini is far less known among historians. Yet his ‘dogma of the independence of nations’ proved to be fundamental during the 1919 Peace Treaties, when the rights of nationality became the criterion redesigning the map of Europe – nationality being officially attached to the promise of self-determination by President Woodrow Wilson.

This article intends to present the principle of nationality advocated by Mancini and how it became the basis of relations between states in international law in the second half of the nineteenth century. It also aims to analyse how the principle of nationality was transposed, formulated and interpreted in the 1919 Peace Treaties to support the rights of national minorities.
