Published: June 2024

This research presents the first molecular characterization of the freshwater leech Hemiclepsis marginata (O. F. Müller, 1773) within the Ferghana Valley and Uzbekistan, shedding light on a species sparsely documented in Uzbekistan and Central Asia. Through detailed examination, we elucidate its morphology and biological attributes, while also providing a comparative analysis with specimens from the Oriental region. The leech was assigned to the Palearctic taxon Hemiclepsis marginata marginata, which exhibits species-level genetic differences from the Oriental Hemiclepsis marginata asiatica Moore, 1924. Our investigation reveals its parasitic relationship with the Aral basin snowtrout Schizothorax eurystomus Kessler, 1872 and the marsh frog Pelophylax ridibundus (Pallas, 1771). A distribution map and imagery of the newly recorded leech enrich our understanding of its ecology and distribution.

The Strategy to Improve MSME Performance through Entrepreneurial Orientation, Organizational Readiness, Knowledge Management, and E-Commerce Adoption
Authors: 'Aliyah Himmatul , Wahyuni Sari
Published: June 2024

Micro, Small and Medium Enterprises (MSMEs) are among the most important contributors to the Indonesian economy. In the digital era, using e-commerce is one of the strategies to face the increasing competition in the business world. However, MSMEs in Indonesia are still faced with various obstacles, primarily related to the lack of mastery of technology and the unoptimized utilization of e-commerce in business. Based on this, it is necessary to check the factors that can enhance MSME performance. This study aims to analyze the influence of entrepreneurial orientation, organizational readiness, knowledge management, and e-commerce adoption, which are expected to improve MSME performance in the digital era. Partial Least Squares Structural Equation Modeling (PLS-SEM) is used to test the relationship between these variables. This study involved 241 MSME owners/managers who have adopted e-commerce in their businesses in the food and beverage industry. The results showed that entrepreneurial orientation, organizational readiness, knowledge management, and e-commerce adoption can significantly improve the performance of MSMEs in food and beverage businesses. These findings better explain how MSME players can optimally improve capabilities and organizational resources to achieve sustainable competitive advantage and superior business performance.
What next after hyper-globalization and export-oriented industrialization?
Authors: Rodrik Dani
Published: June 2024

This paper delves into the evolving landscape of the global economy and its implications for countries like the Philippines. It explores the emerging paradigms that are reshaping economic policies worldwide. Traditionally, economic policies were anchored domestically in exportoriented industrialization models for rapid economic growth. However, the efficacy of this model is waning in the face of technological advancements and changing global dynamics. The hyper-globalization era, marked by financial integration and expanding free trade agreements, prioritized global competition over national interests. But geopolitical tensions, particularly between the US and China, are disrupting the notion of deep economic integration that was once deemed normal. Amidst these shifts, the paper envisions three potential scenarios: a 1930s-style collapse of the world economy (bad), increased weaponization of interdependence and rising geopolitical conflicts (ugly), and a better balance between domestic political autonomy and global integration, fostering a conducive environment for reconstructing national social contracts (good). The paper proposes a shift towards a different economic model focusing on the creation of “good jobs”, characterized by productivity levels that enable the creation of a middle class. These are expected to predominantly emanate from the services sector, particularly non-tradable services. This paper offers some insights for policymakers and stakeholders navigating through these transformative times. As the world economy undergoes profound changes, embracing new approaches and an experimental mindset become imperative for charting a sustainable path forward.

Pozitivizm Odağında Hüseyin Cahit Yalçın ve Hippolyte Taine
Authors: Dumlu Ogeday , Topçu Hayrunisa
Published: June 2024

Pozitivizm, 19. ve 20. yüzyıllarda öne çıkan felsefi akımlardandır. Saint-Simone’un çalışmalarıyla başlamış, Auguste Comte’un çalışmalarıyla öne çıkmıştır. Comte’un takipçilerinden Hippolyte Taine isimli Fransız düşünür, pozitivist görüşleri edebiyat, özellikle de eleştiri alanına uygulamıştır. Onun düşüncesinin temelinde edebiyat eserlerinin toplumsal bir belge özelliği taşıdığı ve edebiyat eserlerindeki olay örgüsü, karakter gibi çeşitli unsurların tesadüfen ortaya çıkmadığı iddiası vardır. Bu iddiasını ırk, muhit, an kavramlarıyla desteklemiştir. Adı geçen kavramlar; kişilerin doğuştan gelen özelliklerini, insanın yaşadığı ortamı ve içinde bulunulan dönemi kapsar. Bu kavramların pozitivizmle ilişkisi, nedensellik ilkesi ile birbirlerine bağlı olmaları ve edebiyat eserinin bütününe işaret etmeleridir. Pozitivizm 19. yüzyılda Osmanlı aydınları arasında da benimsenen bir görüş olmuştur. Bu çalışmada Servet-i Fünûn yazarlarından Hüseyin Cahit Yalçın yayımlanan 29 yazısı Hippolyte Taine’nin görüşleri ve pozitivizm ışığında incelenmiştir. Bu yazılardaki özellikle sanat ve eleştiri kavramlarının pozitivist algı ışığında değerlendirildikleri tespit edilmiştir.

Published: June 2024

Background: Poorly differentiated thyroid carcinoma (PDTC) accounts for a small portion of thyroid carcinomas but contributes to a significant proportion of thyroid carcinoma-associated deaths. The clinicopathological prognostic factors and clinical outcomes of PDTC remain unclear. We aimed to evaluate the clinical outcomes of patients with PDTC after curative treatment.Methods: A comprehensive search was performed up to September 2023. We included studies investigating treatment outcomes in patients with PDTC who underwent initial surgery. The 5-year disease-free survival (DFS) and overall survival (OS) were extracted. In this meta-analysis, the enrolled PDTC histological criteria included 3rd, 4th, and 5th World Health Organization (WHO) and Memorial Sloan Kettering Cancer Center (MSKCC) classification. A random-effects model was used for the pooled proportion analysis. Meta-regression analysis was conducted to evaluate the prognostic factors.Results: Twenty retrospective studies published between 2007 and 2023, including 1,294 patients, met all inclusion criteria. Studies that diagnosed PDTC based on various histological criteria including 3rd WHO (n=5), 4th WHO (n=12), 5th WHO (n=2), and MSKCC (n=1) were included. Overall, 5-year DFS and 5-year OS were 49.4% (95% confidence interval [CI], 42.3 to 56.4) and 73.8% (95% CI, 66.5 to 79.9), with moderate heterogeneity of 58% and 55%, respectively. In meta-regression analysis, extrathyroidal extension (ETE) was a prognostic factor for OS.Conclusion: The meta-analysis of DFS and OS in patients with PDTC show the moderate heterogeneity with a variety of histological criteria. ETE appears to have a significant impact on OS, regardless of histological criteria.

Published: June 2024

Sosyal bir varlık olarak insan; toplumu oluşturan, onu şekillendiren, dönüştüren öğeyi oluşturmaktadır. İnsan ve toplum arasındaki sıkı bağ, malzemesi insan olan edebiyatın da ana kaynağını oluşturmaktadır. Bu bağlamda düşünüldüğünde edebi eserlerde toplumu yansıtan öğelerin yer alması, insanın toplum içindeki varlığının irdelenmesi sıklıkla kullanılmaktadır. Gerçekçilik akımının ardından toplum içerisindeki sınıfları, zengin ile fakir arasındaki derin uçurumları gözler önüne seren toplumsal gerçekçilik, edebi metinlerde kurguda yer alan olay örgüsünün arka planında işlemekte olan toplumsal yapıyı okura aktarmaktadır. Sıradan insanın kapitalizmin ağır şartları altında yaşayabilmek için ihtiyaç duyduğu paranın zengin sınıfın elinde adeta oyuncak gibi kullanıldığı görülmektedir. Özellikle Rus toplumsal gerçekçiliği “küçük insan”ın yaşadıklarını, paranın yaşamın devam edebilmesi için kazanılmasında yaşanılan zorlukları tüm çıplaklığı ile irdeler ve dünya edebiyatını “küçük insan” teması ile tanıştırır.
Bu çalışmada Yaşar Kemal’in Hüyükteki Nar Ağacı ile Tolstoy’un Polikuşka adlı eserlerindeki köylü sınıfı toplumsal gerçekçilik bağlamında değerlendirilmeye çalışılacaktır. Her iki eserde yer alan toplumsal sınıflar arasındaki derin uçurum, yaşamaları için ihtiyaç duyulan parayı kazanabilmek için roman kahramanlarının yaşadıkları ve hayata karşı olan umutlarının karşılaştıkları katı gerçeklik sonrası yok olması dikkat çekmektedir. Bu bağlamda her iki yazarın eserinde insanı ayakta tutan umudun yok olması sonucu, yenildiklerini kabul eden roman kahramanlarının yaşadıkları okura oldukça etkileyici bir üslupla aktarılmaktadır.
Geospatial Analysis of Urban Metamorphosis and implication on Development Control in Ile-Ife, Osun State, Nigeria
Authors: Ajala Olayinka , Remilekun Olaiya , OLABAMIJI AFOLABI
Published: June 2024

Cities in developing countries experience rapid expansion, which has a negative effect on the aesthetic value of the city. This paper thus examined urban metamorphosis and development control with the specific objectives of assessing the physical development between 1986 and 2018 and assessing residents’ perceptions of development control regulation and challenges of development control enforcement as regards to road setbacks in Ile-Ife, Osun State. Landsat images were used to examine changes in the physical development (built-up) in Ile-Ife. A questionnaire and key informant interview were used to examine residents’ perceptions of development control regulation and the challenges of development control enforcement. The result showed that built-up area increased from 2760.05ha (94.81%) between 1986 and 2002 to 6843.41ha (120.67%) between 2002 and 2018, and 9603.46ha (329.87%) between 1986 and 2018. Between 1986 and 2018, a recorded annual magnitude and frequency of 9603.46ha and 600.22 ha were built up. The study revealed that 60% of the informants confirmed that the planning authorities were grappling with inadequate funds and inadequate technical and manpower, which had resulted in their inability to undertake planning activities. The study concluded that rapid development had negatively affected development control in the study area. It is therefore recommended that the government strengthen the planning authority, subsidize the cost of plan approval, and provide easy access to building permits.

Published: June 2024

This paper seeks to explore the state of financial literacy of Gen Z employees in Kolkata to establish the extent of their capacity to make sound financial decisions. As India has a large population of the young generation, it is equally important to understand the perception of the youth regarding financial literacy for the country’s economic advancement. The study uses primary data collected from respondents using a structured questionnaire among adults aged 18-29 years. The statistical tests used to analyze the data included ANOVA and ROC Curve, while data analysis was performed using Microsoft Excel and SPSS. These results suggest that the degree of financial literacy is not affected by age or sex but by education level and type. These findings are evidence that further supports the need for effective financial education strategies to improve financial literacy among young employees and foster more and improved financial decisions in the economy.

NETWORK TIES, ENTREPRENEURIAL CREATIVITY AND COMPETITIVE ADVANTAGE: THE MODERATING ROLE OF KNOWLEDGE INTEGRATION CAPABILITY
Authors: Juniariani Ni Made Rai , Agustia Dian
Published: June 2024

This study aims to examine the moderating effect of knowledge integration capability on the relationship between business ties, political ties, and entrepreneurial creativity on competitive advantage. We present the first model that links the ability to integrate knowledge, network ties, and entrepreneurial creativity with the background of MSMEs in Indonesia. This study’s data collection method is a questionnaire survey given to Indonesian MSME entrepreneurs. Meanwhile, 358 questionnaires have been qualified for further processing as part of the random sampling approach used in this study’s sample collection. Additionally, the survey data were acquired through the use of SmartPLS, and the study’s findings indicate that business ties, political ties, and entrepreneurial creativity all favorably impact competitive advantage. Knowledge integration capability reinforces the influence of business ties and entrepreneurial creativity on competitive advantage. But knowledge integration capability is unable to counteract the impact of political ties on competitive advantage. The results complement the literature related to the use of knowledge resources in achieving competitive advantage. Considering the important role of knowledge integration capability in the escalation of competitive advantage in corporations, MSME entrepreneurs are strongly advised to consider the available resource of knowledge. To preserve the competitive advantage, knowledge should be continuously expanded.
IDENTIFICATION OF SOFTWARE QUALITY ATTRIBUTES FROM CODE DEFECT PREDICTION: A SYSTEMATIC LITERATURE REVIEW
Authors: Rumbutis Lukas , Slotkienė Asta , Pliuskuvienė Birutė
Published: June 2024

Identifying and understanding reasons for deriving software development defects is crucial for ensuring software product quality attributes such as maintainability. This paper presents a systematic literature review and the objective is to analyze the suggestions of other authors regarding software code defect prediction using machine learning, deep learning, or other artificial intelligence methods for the identification of software quality. The systemic literature review reveals that many analyzed papers considered multiple software code defects, but they were analyzed individually. However, more is needed to identify software quality attributes. The more profound analysis of code smells indicates the significance when considering multiple detected code smells and their interconnectedness; it helps to identify the software quality sub-attributes of maintainability.

Published: June 2024

It is beneficial to calibrate the period–Wesenheit–metallicity relation (PWZR) of Delta Cephei stars (DCEPs), i.e., classical Cepheids, using accurate parallaxes of associated open clusters (OCs) from Gaia data release 3 (DR3). To this aim, we obtain a total of 43 OC–DCEPs (including 33 fundamental mode, 9 first overtone mode, and 1 multimode DCEPs) and calibrate the PWZR as

The concurrently obtained residual parallax offset in OCs, zp = −4 ± 5 μas, demonstrates the adequacy of the parallax corrections within the magnitude range of OC member stars. By comparing the field DCEPs’ DR3 parallaxes with their photometric parallaxes derived by our PWZR, we estimated the residual parallax offset in field DCEPs as zp = −15 ± 3 μas. Using our PWZR, we estimate the distance modulus of the Large Magellanic Cloud to be 18.482 ± 0.040 mag, which aligns well with the most accurate published value obtained through geometric methods.
H i Lyα Emission from a Metal-poor Cool Stream Fueling an Early Dusty Starburst
Authors: Hall Kevin , Fu Hai
Published: June 2024

The GAMA J0913−0107 system is a rare conjunction of a submillimeter galaxy (SMG) at z ≈ 2.7 and two background QSOs with projected separations <200 kpc. Previous high-resolution QSO absorption-line spectroscopy has revealed high H i column density, extremely metal-poor (∼1% solar) gas streams in the circumgalactic medium of the SMG. Here we present deep optical integral-field spectroscopy of the system with the Keck Cosmic Web Imager (KCWI). Reaching a 2σ surface brightness limit ≈10−19 erg s−1 cm−2 arcsec−2 with ∼2 hr of integration time, we detect a filamentary Lyα nebula stretching ∼180 kpc from the SMG intercepting both QSO sightlines. This Lyα filament may correspond to the same cool gas stream penetrating through the hot halo seen in the absorption. In contrast to Lyα nebulae around QSOs, there is no obvious local source for photoionization due to the massive dust content. While uncertain, we consider the possibility that the nebula is ionized by shocks induced by the infall, obscured star formation, and/or a boosted UV background. The SMG–QSOs conjunction multiplied the efficiency of the KCWI observations, allowing a direct comparison of Lyα nebulae in two distinct environments. We find that the nebulae around the QSOs are much brighter and show steeper surface brightness profiles than the SMG nebula. This is consistent with the additional photoionization and Lyα scattering provided by the QSOs. While illustrating the challenges of detecting Lyα nebulae around SMGs, our work also demonstrates that important insights can be gained from comparative studies of high-z Lyα nebulae.
Fermi GBM Observations of the Galactic Magnetar SGR 1935+2154 during Its 2022 January Activity
Authors: Rehan Noor ul Sabah , Ibrahim Alaa I.
Published: June 2024

The X-ray and radio burst-emitting soft gamma-ray repeater SGR 1935+2154 has been the most active magnetar during the past decade, with at least one active episode each year since 2019. We report on the 2022 January activity as observed by the Fermi Gamma-Ray Burst Monitor and present the temporal and time-integrated spectral properties of the observed 112 X-ray bursts. No radio bursts were reported during the activity. The mean burst duration is comparable to most of the previous activities but is shorter than that of 2020, during which the magnetar emitted radio bursts. The mean burst spectrum is softer than the earlier activities and a long-term softening trend since 2016 is evident and is accompanied by a rise in the mean burst fluence and blackbody emission radii. The power-law indices of the

correlation also show an evolution during 2019–2022, where the soft component started becoming steeper, whereas the hard component shows a less steep trend. The burst properties show no significant evolution within the activity, which lasted for ∼ 45 days, and none of the observed bursts showed properties reminiscent of those of the hard, long X-ray counterpart to the 2020 fast radio burst FRB 200428 from the source. We discuss the results comparatively with the 8 yr history of the source since its discovery in 2014.
Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Observational Characteristics in Different Regions of the Disks
Authors: Liu Jun-Rong , Wang Yi-Lin , Wang Jian-Min
Published: June 2024

Stars and compact objects embedded in accretion disks of active galactic nuclei (AGNs), dubbed accretion-modified stars (AMSs), often experience hyper-Eddington accretion in the dense gas environment, resulting in powerful outflows as the Bondi explosion and formation of cavities. The varying gas properties across different regions of the AGN disk can give rise to diverse and intriguing phenomena. In this paper, we conduct a study on the characteristics of AMSs situated in the outer, middle, and inner regions of the AGN disk, where the growth of the AMSs during the shift inward is considered. We calculate their multiwavelength spectral energy distributions (SEDs) and thermal light curves. Our results reveal that the thermal luminosity of the Bondi explosion occurring in the middle region leads to UV flares with a luminosity of ∼1044 erg s−1. The synchrotron radiation of Bondi explosion in the middle and inner regions peaks at the X-ray band with luminosities of ∼1043 and ∼1042 erg s−1, respectively. The γ-ray luminosity of inverse Compton radiation spans from 1042–1043 erg s−1 peaked at the ∼10 MeV (outer region) and ∼GeV (middle and inner regions) bands. The observable flares of AMS in the middle region exhibit a slow rise and rapid Gaussian decay with a duration of months, while in the inner region, it exhibits a fast rise and slow Gaussian decay with a duration of several hours. These various SED and light-curve features provide valuable insights into the various astronomical transient timescales associated with AGNs.

Published: June 2024

C4H and c-C3H2, as unsaturated hydrocarbon molecules, are important for forming large organic molecules in the interstellar medium. We present mapping observations of C4H (N = 9−8) lines, c-C3H2 (J

Ka,Kb
= 21,2–10,1), and H13CO+ (J = 1−0) toward 19 nearby cold molecular cores in the Milky Way with the IRAM 30 m telescope. C4H 9–8 was detected in 13 sources, while c-C3H2 was detected in 18 sources. The widely existing C4H and c-C3H2 molecules in cold cores provide material to form large organic molecules. Different spatial distributions between C4H 9–8 and c-C3H2 2–1 were found. The relative abundances of these three molecules were obtained under the assumption of local thermodynamic equilibrium conditions with a fixed excitation temperature. The abundance ratio of C4H to c-C3H2 ranged from 0.34 ± 0.09 in G032.93+02 to 4.65 ± 0.50 in G008.67+22. A weak correlation between C4H/H13CO+ and c-C3H2/H13CO+ abundance ratios was found, with a correlation coefficient of 0.46, which indicates that there is no tight astrochemical connection between C4H and c-C3H2 molecules.
Martian Crustal Magnetic Field Effects on the Ionospheric Main Peak
Authors: Chen Yiding , Liu Libo , Le Huijun , Zhang Ruilong
Published: June 2024

Planetary magnetic fields can affect ionospheric plasma transport and coupling with the solar wind. In contrast to the terrestrial global magnetic field, there are only weaker and sporadic crustal magnetic fields on Mars. Many studies have indicated that Martian crustal fields can still modulate the topside ionosphere and its coupling with the solar wind. Nevertheless, it is unclear whether the crustal fields can affect the ionospheric main peak, which does not directly interact with the solar wind and is dominated by photochemical processes. In this study, the crustal field effect was identified from ionospheric measurements over unevenly distributed crustal fields. Both the intensity and configuration of the crustal fields were found to be capable of affecting the ionospheric main peak. The ionospheric peak electron density tends to decrease in the strong horizontal crustal field region. The results suggest that the crustal fields may affect the ionospheric main peak through modulating solar wind energetic particle precipitation; strong horizontal magnetic fields can partially prevent energetic particle precipitation and thus weaken impact ionization.

Two new species of the genus Kingdonella and the first report of a male K. qinghaiensis Zheng, 1990 are presented. The new species K. gandensissp. nov. has similar morphological features to K. wardi Uvarov, 1933, but it differs from the latter in having 1) the hind tibia black; 2) the epiproct, in males, with a median groove in the basal 1/2 and in the apical 1/4; 3) the denticles of the male epiproct black; 4) the outside of the hind femur reddish-brown on the basal 1/4 and black on the apical 3/4; and 5) the ventral face of the hind femur black on the outer side. The second new species, K. biruensissp. nov., is morphologically close to K. pienbaensis Zheng, 1980 but differs from the latter in having 1) the length of the middle segment (12th segment) of antennae 1.2 times longer than its width; 2) the subgenital plate sharp-cornered in males; 3) the ovipositor smooth; 4) the upper half of hind femur outside surface with two black spots; and 5) the ventral face of the hind femur black on its outer side, red on the basal 2/3, and black on the apical 1/3 of its inner side. Finally, we provide a key to all known species of Kingdonella.

Published: June 2024

Background:

This retrospective study investigated the impact of continuing vs discontinuing home oral hypoglycemic medications for patients with diabetes undergoing total hip arthroplasty.

Materials and Methods:

Patients who were not exclusively receiving home oral hypoglycemic regimens were excluded. Additionally, patients whose diabetes was not managed inpatient postoperatively were excluded. Included patients were retrospectively evaluated for early postoperative glycemic control, renal function, and metabolic abnormalities. Patients were then compared based on whether their home oral hypoglycemic regimen was continued vs discontinued in favor of initiating insulin while inpatient and analyzed using multivariable regression analysis.

Results:

A total of 532 patients undergoing total hip arthroplasty met inclusion criteria, with 78.6% continuing their home oral hypoglycemic regimen. Those who continued showed significantly lower median maximum inpatient blood glucose (178.5 mg/dL vs 249.5 mg/dL;
P

Conclusion:

These findings suggest that continuing a home oral hypoglycemic regimen for patients with diabetes after total hip arthroplasty is associated with superior glycemic control without exacerbating renal abnormalities or increasing metabolic complications. [

Echo state network-based adaptive control for nonstrict-feedback nonlinear systems with input dead-zone and external disturbance
Authors: Alhazmi Hadil , Kharrat Mohamed
Published: June 2024

This paper addressed the adaptive control problem for non-strict-feedback nonlinear systems with dead-zone and external disturbances. The design methodology integrated the backstepping technique with the approximation of unknown functions using an echo state network (ESN), enabling real-time adjustments. A comprehensive Lyapunov stability study was conducted to confirm the semi-globally uniformly ultimately boundedness (SGUUB) of all signals in the closed-loop system, ensuring that the tracking error converged to a small neighborhood of the origin. The effectiveness of the proposed method was further demonstrated through two examples, and error assessment criteria were utilized for comparisons with existing controllers.
Least energy solutions to a class of nonlocal Schrödinger equations
Authors: Zhang Yong-Chao
Published: June 2024

We explore a class of nonlocal Schrödinger equations that include not only fractional Schrödinger equations but also other nonlocal Schrödinger equations studied in the literature. We prove the existence of least energy solutions to this class of equations by the variational method, which extends the results obtained by Gu et al. (2018) and Xiang et al. (2019).
What is the in-host dynamics of the SARS-CoV-2 virus? A challenge within a multiscale vision of living systems
Authors: Bellomo Nicola , Eftimie Raluca , Forni Guido
Published: June 2024

This paper deals with the modeling and simulation of the in-host dynamics of a virus. The modeling approach was developed according to the idea that mathematical models should go beyond deterministic single-scale population dynamics by taking into account the multiscale, heterogeneous features of the complex system under consideration. Here, we considered modeling the competition between the virus, the epithelial cells it infects, and the heterogeneous immune system with evolving activation states that induce a range of different effects on virus particles and infected cells. The subsequent numerical simulations showed different types of model outcomes: from virus elimination, to virus persistence and periodic relapse, to virus uncontrolled growth that triggers a blow-up in the fully activated immune response. The simulations also showed the existence of a threshold in the immune response that separates the regimes of higher re-infections from lower re-infections (compared to the magnitude of the first viral infection).
Le marqueur ONLY en tant que connecteur argumentatif
Authors: Pennec Blandine
Published: June 2024

L’étude porte sur un emploi spécifique du marqueur only, à savoir son emploi en tant que ligateur interpropositionnel et transphrastique (permettant de conjoindre des propositions ou même des phrases entre elles). Le statut syntaxique précis de only dans cet emploi est discuté, afin de déterminer s’il s’agit d’une conjonction à proprement parler ou d’un adverbe de liaison. C’est ensuite son statut discursif qui est questionné, en mettant en contraste les propriétés d’un connecteur et celles d’un marqueur de discours. Ce faisant, c’est également la dimension argumentative de only dans cet emploi qui est mise en lumière. Ses effets de sens en contexte sont examinés, en lien avec les configurations d’accueil, puis ils sont ramenés à un dénominateur commun, à savoir sa valeur fondamentale. Les facteurs conduisant aux différentes interprétations possibles de only dans cet emploi sont enfin passés au crible.
Le démantèlement des fortifications de Valenciennes (1891-1893)
Authors: Salamagne Alain
Published: June 2024

Le démantèlement de l’enceinte urbaine de Valenciennes conduite rapidement de 1891 à 1893 a fait disparaître un patrimoine architectural et archéologique de premier ordre, d’autant que les remparts de terre accumulés par les ingénieurs de la Renaissance avaient enfoui un ensemble de structures (courtines, tours) dont les plus anciennes remontaient au XIIe siècle. Leur disparition est, en partie, compensée par une documentation riche procédant soit des archives du démantèlement, soit des campagnes photographiques opérées alors par les photographes. Ces documents révèlent encore les techniques mises en œuvre à la fin du XIXe siècle dans le cadre de ces vastes chantiers de destruction.
La réunion de la Ville et de la Cité d’Arras : une opération de démantèlement complexe (1531-1777)
Authors: Béghin Mathieu , Bray Victoria
Published: June 2024

Par son caractère bicéphale depuis le IXe siècle, Arras représente pour Charles Quint un point de faiblesse dans la défense de la frontière méridionale de son empire. C’est pour cela qu’en 1531 il demande aux Ville et Cité d’Arras de fusionner leurs enceintes respectives en un seul et même périmètre fortifié. Toutefois, les travaux ne sont pas réalisés, car les différents pouvoirs administrant Arras considèrent cette entreprise comme une perte de privilèges. Cette situation donne lieu à de nombreuses négociations entre le pouvoir impérial et les édiles arrageois qui, bien que résistants sur le démantèlement, doivent céder sur une liaison fortifiée entre les deux enceintes. Ce n’est finalement qu’en 1749, soit presque un siècle après l’intégration d’Arras au royaume de France, que Ville et Cité s’entendent sur la nécessité de réaliser cette vaste entreprise, laquelle est alors validée par le roi de France, Louis XV. Les tractations du XVIe siècle, ainsi que les opérations de démantèlement des fortifications entre Ville et Cité, puis le lotissement des terrains démilitarisés, ont laissé une vaste production documentaire (textuelle et planimétrique) qui, dans sa très grande majorité, demeure inédite. Ainsi, la présente synthèse propose d’étudier cette opération urbanistique d’envergure qui met plus de deux siècles à se réaliser, en abordant dans un premier temps les relations entre les habitants de la Ville et de la Cité, puis entre les Arrageois et les pouvoirs princiers. Ensuite, le processus de liaison fortifiée au XVIe siècle, ainsi que le déclassement et le démantèlement des fronts défensifs au XVIIIe siècle retiendront notre attention. Enfin, le propos se conclura par l’analyse du lotissement des anciennes lignes défensives selon les nouveaux principes urbanistiques de l’époque.
Morceaux choisis. Le démantèlement sélectif des remparts de Cambrai à la fin du XIXe siècle
Authors: Roumegoux Yves
Published: June 2024

Comme bien d’autres villes du pré carré, du moins celles qui en ont les moyens, la municipalité de Cambrai obtient, en 1892, le déclassement de la place par les autorités militaires. Le démantèlement des remparts, qui durera jusqu’en 1896, constitue une charge financière importante pour la ville, puisqu’elle représente alors près d’un cinquième des dépenses communales. En outre, les travaux sont freinés par de puissants mouvements d’opinion locaux, comme la Société d’Émulation de Cambrai, qui souhaitent sauvegarder le plus possible les vestiges du passé. Ainsi, certains éléments emblématiques de l’enceinte, tels que les portes, ont été conservés (la porte de Paris, datée de la fin du XIVe siècle, a été sauvée à une courte voix de majorité !) et transformés en « arcs de triomphes » glorifiant la ville et son passé, mais totalement coupés de leur contexte. Les tours, moins « recyclables », moins aptes à s’intégrer dans l’urbanisme nouveau, s’en sont moins bien sorties (la tour d’Abancourt est détruite en 1948 après avoir été rayée de l’inventaire des monuments historiques). La destruction sélective d’un ensemble fortifié, en conservant certains morceaux choisis, médiévaux de préférence, comme témoins du passé millénaire de la cité et de son identité, est en cela particulièrement exemplaire à Cambrai.
Béthune, aspects d’un démantèlement précoce au service d’une renaissance urbaine (1866-1878)
Authors: Machinet Léo , Manceau Christopher
Published: June 2024

À la suite de son intégration définitive dans le royaume de France en 1713, la ville de Béthune perd progressivement son importance militaire. Les finances peinent à maintenir en état satisfaisant des fortifications qui apparaissent impossibles à adapter aux dernières évolutions de la poliorcétique. Au terme de cette stagnation, le déclassement de la place forte est prononcé par le décret du 26 juin 1867 permettant d’envisager le démantèlement de l’enceinte militaire. La particularité du cas béthunois réside dans sa précocité en comparaison avec les villes voisines. Une volonté de faire « table rase » pour faire entrer Béthune dans la modernité est incarnée par le maire d’alors, Charles Delisse-Engrand. Aujourd’hui, 150 ans après cette renaissance urbaine, quelques témoins d’enceinte demeurent çà et là, offrant un regard fugace sur leur aspect, mais aussi sur le décalage entre les intentions et la réalisation d’une démolition imparfaite. Le présent article propose un aperçu de la politique de démantèlement des fortifications de Béthune et des raisons variées quant à la survie de certains vestiges.
Les Sonderbauten du Pas-de-Calais
Authors: Deschamp Marc
Published: June 2024

Au cours de la Seconde Guerre mondiale, le IIIe Reich entreprend dans le Pas-de-Calais la construction de cinq grands bunkers, nommés Sonderbauten (Constructions spéciales en français), pour employer certaines de leurs armes secrètes. Massivement attaqués, ces édifices n’ont jamais été mis en service lorsque les Alliés les capturent en septembre 1944. Français et Britanniques héritent alors des bunkers dont ils doivent décider de leur conservation ou de leur abandon. Progressivement, toutes les infrastructures perdent leur utilité militaire pour devenir, selon les cas, des sites sauvages ou des musées ouverts au public, prenant le contre-pied total de leur fonction première.
Le château d’Étaples a-t-il été démantelé au XVIIe siècle ?
Authors: Byhet Thomas
Published: June 2024

La littérature historique ayant pour sujet le château d’Étaples indique que cette forteresse a subi un démantèlement dans la première moitié du XVIIe siècle. Ce démantèlement repose, cependant, sur des sources discutables et sa datation demeure incertaine. Il paraît avoir été mené lors de la régence de Marie de Médicis, et plus particulièrement dans le cadre de la lutte que mènent les princes du sang et leurs partisans contre le pouvoir royal entre 1613 et 1617. Mais on l’attribue également à la politique de destruction des fortifications des places fortes du royaume de France conduite par Richelieu à partir de 1626. Cette étude a pour objectif de déterminer la réalité de cet acte à travers plusieurs sources documentaires, non encore exploitées jusqu’à maintenant.
Le démantèlement des fortifications à travers la photographie
Authors: Fourmanoir Jérôme
Published: June 2024

Devenues pour la plupart inutiles à la fin du XIXe siècle, les fortifications des villes d’Arras et de Douai vont être démantelées à partir de 1891 pour laisser place à de nouvelles constructions. De nombreux artistes vont s’intéresser à ces éléments tout au long du XIXe siècle, comme Camille Corot, Charles Desavary, Constant Dutilleux, Henri Duhem, etc. Les photographes vont aussi contribuer à cet engouement, comme Joseph Quentin (1857-1946) pour la ville d’Arras et Augustin Boutique (1862-1944) pour la ville de Douai. Des regards croisés sont ainsi possibles entre la peinture et la photographie, mettant, ou non, en avant l’originalité de ces photographies, aujourd’hui éléments importants de la patrimonialisation des fortifications disparues.
La paix du guerrier. Gens de guerre et gestion des conflits dans les lettres de rémission au xve siècle
Authors: Verreycken Quentin
Published: June 2024

La place des gens de guerre dans les pratiques d’accord et d’apaisement à la fin du Moyen Âge reste encore mal connue. L’étude des lettres de rémission accordées par le roi de France et le duc de Bourgogne au xve siècle montre pourtant que les soldats n’échappent pas aux impératifs de réconciliation, en particulier dans le cadre de la procédure de grâce où la paix à partie est une étape indispensable à l’entérinement des lettres. De plus, la résolution d’un conflit à l’armée nécessite l’intervention des autorités militaires qui peuvent alors jouer le rôle d’intermédiaires ou d’arbitres entre les parties. À une échelle plus générale, l’abolition décrétée à l’occasion d’un traité de paix efface définitivement les violences commises de part et d’autre et facilite l’apaisement des tensions entre anciens belligérants.
« Déceler l’accord entre parties dans les procès pour dette : un exemple de justice négociée à la fin du xvie siècle au tribunal des échevins de Nancy »
Authors: Pezzetta Jonathan
Published: June 2024

La négociation occupe une place centrale dans la résolution des litiges sous l’Ancien Régime. Souvent, les tentatives des parties à s’accorder commencent avant que ne soient sollicitées les autorités judiciaires. Pendant un procès, les acteurs poursuivent leurs tractations en dehors de l’auditoire. La fin des négociations marque généralement la résolution du conflit, d’où un taux d’évaporation des affaires portées en justice très important. Paradoxalement, malgré l’omniprésence de la négociation dans les litiges, elle ne laisse que peu de traces dans les sources judiciaires. C’est le cas notamment de documents aussi vastes que les registres des causes du tribunal des échevins de Nancy, instance souveraine située au cœur de la capitale du duché de Lorraine. Ces recueils datés du xvie au début du xviie siècles contiennent tous les procès civils jugés annuellement par l’échevinage. Un registre se détache du lot : le registre en matière de contredits des années 1597 et 1598 qui ne contient que des affaires de saisies et de grosses dettes. Le présent article part de l’hypothèse que les intérêts réciproques entre créanciers et débiteurs dans ces affaires leur donnent davantage de raisons de parvenir à un consensus et donc de négocier que de ? Il s’agit d’explorer cette source et d’établir un protocole pour en déceler les traces d’accords.
S’accorder. La régulation sociale dans les justices locales de l’Ouest parisien au xviiie siècle

Les populations des environs de Paris au xviiie siècle confiaient-elles le règlement de leurs différends à la justice ou bien s’arrangeaient-elles seules devant un notaire ? Autrement dit, quels rapports existait-il entre la justice comme vertu et les tribunaux de première instance comme administration ?
