Introduction. Direct oral anticoagulants (DOAC) rivaroxaban and apixaban have significantly reduced the risk of developing venous thromboembolic complications (VTEC). However, the use of DOAC may be associated with a higher risk of bleeding, especially actual in patients after total hip arthroplasty (THA).Material and methods. We enrolled 38 patients with moderate osteoarthritis of the hip joints undergoing THA. The mean age of patients was 58 (33; 85) years. All the patients received rivaroxaban or apixaban in the doses specified by Russian clinical guidelines for the diagnosis, treatment and prevention of venous thromboembolic complications (VTEC). Retrospectively, in the postoperative period, the patients were divided into two groups: Group 1 — 31 patients (20 women and 11 men), who had no hemorrhagic complications after hip replacement; and Group 2 — 7 patients (4 women and 3 men) who experienced hemorrhagic events in the form of hematomas in the wound area. Laboratory tests were performed for all patient baseline (1st day of hospitalization), after surgery (1st day after THA), and on the 7th day after THA. Analyses included the determination of hemostasis parameters (INR, aPPT, fibrinogen, D-dimer), hematological (HGB, PLT, RBC) and biochemical parameters (calcium, ionized calcium, serum iron, hs-CRP).Results. The analysis of biochemical parameters in patients with hemorrhagic complications revealed a significant increase of fibrinogen (p=0,023) compared with uncomplicated cases. Serum iron concentration in men with hemorrhagic complications in the postoperative period was significantly lower than in patients without complications. In patients with hemorrhagic complications, the ionized calcium was lower (p=0,032) than in patients without complications, but within the reference values. The hs-CRP concentration in the group with hemorrhagic complications was twice higher than in the group without complication and eight times above the reference values.Conclusion. The concentration of iron in the blood serum in men below 11 mmol/l and a slight hyperfibrinogenemia of 4.65 g/l in all the patients are the risks of developing hematomas in the area of surgery. These parameters should be used to predict the risk of hemorrhagic complications in patients before THA and recommended for control before the surgery and on the 1st day after THA (hs-CRP).

Abstract. Aortic dissection is a rupture of the inner layer of the aorta with subsequent penetration of blood into the degeneratively altered middle layer with the formation of false lumen and true lumen. Pregnancy is one of the risk factors for the development of aortic dissection. The incidence of aortic dissection during pregnancy is only 0.0004% of cases.Aim of the study. To analyze national and foreign literature, as well as share own clinical observations in the diagnosis and treatment of patients with aortic dissection in the postpartum period.Material and methods. Two patients after successful childbirth, in the late postpartum period, were admitted with a diagnosis of aortic dissection type A according to Stanford.CT angiography confirmed the presence of Stanford type A aortic dissection. After additional examination, surgical treatment was performed to replace the aortic valve and ascending aorta under artificial circulation, with a satisfactory clinical result.Conclusion. The diagnosis of aortic dissection should be considered in all pregnant women with chest pain, as this condition often goes undiagnosed.The pregnancy period is one of the risk factors for the development of aortic dissection with a high mortality rate. The likelihood of developing aortic dissection in women at risk peaks in the third trimester and the first 12 weeks after delivery.The risk group should include women with confirmed syndromic and non-syndromic genetic diseases, bicuspid aortic valve, coarctation of the aorta, or at least one major criterion indicating the presence of aortopathy (ectopia lentis, aortic aneurysm, habitus, genetic testing).If Marfan syndrome is present, surgical intervention should be considered if the maximum aortic diameter is more than 4.5 cm before pregnancy. In women with Marfan syndrome and aortic dissection in the family history, as well as in the presence of more aggressive genetic diseases (Loeys-Dietz syndrome, Ehlers-Danlos syndrome), it is possible to consider preventive surgical treatment for an aortic diameter of 4.0 cm or more.The delivery in high-risk patients is recommended to be performed in a hospital that has a cardiac surgery service and an “aortic” team.
QUASARS – POINTERS TO AN INFINITE, ETERNAL AND DIALECTICAL UNIVERSE AND A REPUDIATION OF THE BIG BANG COSMOLOGY
Authors: Malek Abdul 
Published: November 2023

Quasars (quasi-stellar [star-like] radio sources) represent the critical criteria for choice between two opposite and widely different ontological and epistemological narrative of the universe. The first one, which is mainly based on mathematical idealism, views the universe as deterministic and an essentially unidirectional condensation of diffuse matter created through a single primordial explosion (The Big Bang) about 13.8 billion years ago. The second view, based on (limited) observational and empirical evidence asserts a rather intrinsic and dialectical evolution (appearance/disappearance) of matter and motion in this infinite, eternal and ever-changing universe; where new cosmic bodies are formed from ejected and/or dissipated newly created material; from the core of the existing cosmic bodies.; mediated by chance and necessity. Evidence and resource materials provided in this article clearly favours the dialectical narrative of the universe.
Homogeneity and heterogeneity in lexical stress placement among Ugandan speakers of English as an L2: a view from usage-based perspective
Authors: Adokorach Monica , Isingoma Bebwa 
Published: November 2023

Abstract
The study delineates divergences that set apart the Ugandan accent from RP with respect to primary lexical stress placement, as well as divergences that evince variability among Ugandans. For example, differences from RP were (almost) homogenously observed in the words effect, cassava, agreement, arrest, alarm, with stress placed on the first syllable of all these nouns, while inter-speaker variability was substantially observed in words such as bursar, further, with some speakers placing stress on both syllables of the words, while others had the stress on the first syllable only. Analogy and underlying substrate influence account for the divergences, with substrate influence considered along the lines of what Wells (1982) refers to as ‘lexical distribution.

The European Union as a “Nation”: The “Nation” that Effaces Itself?
Authors: Maxwell Alexander , Roberts Jack 
Published: November 2023

Abstract
This article examines the European Union (EU) in light of Benedict Anderson's definition of the nation as “an imagined community … imagined as inherently limited and sovereign.” Current scholarship mostly rejects the possibility of an EU nation, or treats it only as a possible eventuality, not a current reality. Interpreting Andersonian “sovereignty” through the lens of political legitimacy, the EU nevertheless satisfies all four of Anderson's criteria, since members of the EU Parliament invoke a “European people” to legitimize their actions. EU nationhood coexists with other national loyalties. However, multiple national loyalties exist elsewhere in Europe, since British nationhood coexists with Welsh nationhood, German nationhood with Sorbian nationhood, and so on. Eurobarometer evidence also suggests that multiple loyalties are widespread. Treating the EU as a nation offers many analytical advantages, since scholars do not need to struggle with terminological novelties, but can straightforwardly apply the secondary literature on nationalism.
Stringent in-silico identification of putative G-protein-coupled receptors (GPCRs) of the entomopathogenic nematode Heterorhabditis bacteriophora
Authors: Kundu Artha , Jaiswal Nisha , Rao Uma , Somvanshi Vishal Singh 
Published: November 2023

Abstract
The infective juveniles (IJs) of entomopathogenic nematode (EPN) Heterorhabditis bacteriophora find and infect their host insects in heterogeneous soil ecosystems by sensing a universal host cue (CO2) or insect/plant-derived odorants, which bind to various sensory receptors, including G protein-coupled receptors (GPCRs). Nematode chemosensory GPCRs (NemChRs) bind to a diverse set of ligands, including odor molecules. However, there is a lack of information on the NemChRs in EPNs. Here we identified 21 GPCRs in the H. bacteriophora genome sequence in a triphasic manner, combining various transmembrane detectors and GPCR predictors based on different algorithms, and considering inherent properties of GPCRs. The pipeline was validated by reciprocal BLAST, InterProscan, GPCR-CA, and NCBI CDD search. Functional classification of predicted GPCRs using Pfam revealed the presence of four NemChRs. Additionally, GPCRs were classified into various families based on the reciprocal BLAST approach into a frizzled type, a secretin type, and 19 rhodopsin types of GPCRs. Gi/o is the most abundant kind of G-protein, having a coupling specificity to all the fetched GPCRs. As the 21 GPCRs identified are expected to play a crucial role in the host-seeking behavior, these might be targeted to develop novel insect-pest management strategies by tweaking EPN IJ behavior, or to design novel anthelminthic drugs. Our new and stringent GPCR detection pipeline may also be used to identify GPCRs from the genome sequence of other organisms.
Parasite load effects on sex ratio, size, survival and mating fitness of Heleidomermis magnapapula in Culicoides sonorensis
Authors: Mullens Bradley A. , Luhring Katherine A. 
Published: November 2023

Abstract

Heleidomermis magnapapula parasitizes the blood-feeding midge Culicoides sonorensis. Most (84%) single mermithid infective second stage juveniles (J2) developed into adult females, while parasitism by multiple J2 yielded 97% male adults. Nematodes emerged from the midge larval host as adults and mated immediately; females were ovoviviparous. Host larvae were exposed to nematode J2 and examined intact microscopically to score initial parasite load. Midge hosts were reared individually. Premature midge death, nematode survival within the host, and emerging adult nematode sex ratio and size as a function of load and host size were all tracked. Higher nematode loads produced smaller adult nematode males. The higher loads also increased and accelerated premature host death. Emergence of > 7–9 adult nematode males was rare, but up to 19 tiny males emerged from a single host. Larger midges supported higher parasite loads and a larger total volume of emerged nematode biomass. Virgin adult nematode males then were paired with females of variable, known sizes (volume) and held to determine size effects on fertility (egg hatch), and male survival (longevity). Tested adult males ranged in size from 0.0025 – 0.0334 mm3 and females from 0.0121 – 0.1110 mm3. Logistic regression indicated female nematode fertility was positively influenced by male nematode size, while nematode load and female nematode size had no significant effect. While fertility was reduced statistically in smaller males, even some of the smallest male and female individuals could be fertile. Findings are related to field studies in this system.
Don’t Write Off the Absentee Author: Why the Problems of Divine Hiddenness and Neglect Don’t Destroy Vanhoozer’s Authorial Analogy
Authors: Settecase Parker 
Published: November 2023

Abstract
Kevin Vanhoozer’s authorial analogy for the God-World relation is a strong explanatory analogy which can aid Christians in thinking deeply, fruitfully, and systematically about the God they worship and His relationship to His creation. According to this analogy, God relates to His world in an analogous fashion to that of an author to his or her novel. However, the absolute sovereignty at play in the authorial analogy might serve to exacerbate the problems of divine hiddenness and divine neglect. Taken together and applied to the authorial analogy, I will call this the Absentee Author problem. The Author is absent from those characters who are open to relationship with Him and is likewise absent in situations wherein we would expect Him to lovingly intervene in His story, and furthermore, there doesn’t seem to be any good reason for His absence. If Vanhoozer’s authorial analogy does in fact produce the Absentee Author problem and can offer no defense against it, then perhaps we ought to countermand its use, or at least severally limit its proposed explanatory scope. In this paper, I will argue that while Vanhoozer’s authorial analogy might appear to exacerbate the problems of hiddenness and neglect at first glance, ultimately Vanhoozer’s particular model can provide unique and orthodox answers to these problems which not only exculpate the analogy but commends its further use in theology and philosophy of religion.
Epistemic Paradox as a Solution to Divine Hiddenness
Authors: Seymour Amy 
Published: November 2023

Abstract
I offer a new, limited solution to divine hiddenness based on a particular epistemic paradox: sometimes, agents knowing about a desired outcome or relevant features of that desired outcome would prevent the outcome in question from occurring. I call these cases epistemically self-defeating situations. This solution, in essence, says that divine hiddenness or silence is a necessary feature of at least some morally excellent or desirable states of affairs. Given the nature of the paradox, an omniscient being cannot completely eliminate hiddenness, just as an omnipotent being cannot create a rock so heavy that they cannot lift it. Epistemically self-defeating situations provide an undercutting defeater for the assumption that any nonresistant nonbeliever could always, at any time, be in conscious relationship with a perfectly loving God. Thankfully, silence is a temporary feature of epistemically self-defeating situations: once the outcome is achieved, agents can know in full.
Pros and Cons of Online Social Support Exchange on Social Networking Sites: A User’s Perspective
Authors: Lyubenko Roman 
Published: November 2023

Abstract
The article dissects the subject of online social support exchange on social networking sites, or SNS (mostly Facebook and Instagram) through the eyes of the platforms’ active users. Drawing on 20 semistructured in-depth interviews with SNS users from Ukraine, it discusses both the benefits of support exchange in the online realm, such as speed, resilience, unobtrusiveness, and its drawbacks, such as depersonalization, ‘ghosting,’ and privacy concerns. The text also explores the sentiments towards some of the main digital instruments of exchanging support on SNS, in particular posts and various forms of “likes,” as well as the perceived effectiveness of online social support in general. Additionally, it provides some context on how the phenomenon has been impacted by the 2022 Russian invasion of Ukraine.
Makrodaten: Die amtliche Statistik stärken
Authors: Bachmann Rüdiger , Balleer Almut , Enders Zeno , Garnadt Niklas , Stüber Heiko 
Published: November 2023

Abstract
Despite some progress, German macroeconomists are generally dissatisfied with access to important data in Germany. Legal, technical and organisational obstacles abound, in particular as far as mergers of data sets from heterogeneous sources are concerned. This article suggests a number of concrete measures, including legal changes, to improve the situation. Easy access to a variety of data sources is a necessary condition for the design, evaluation, and thus, for the improvement of macroeconomic policies. Better informed decisions are also less prone to be influenced by lobbyists.

Abstract
As a result of the Russian war of aggression against Ukraine, energy prices have risen sharply. In order to fully assess the consequences of this energy crisis for households in Germany, the German Advisory Council for Consumer Affairs (SVRV) is conducting a representative household panel survey from April 2023 to July 2024 with a total of six survey waves. So far, two waves have been carried out with more than 4,444 participating households in April/May and June/July 2023, respectively. In the present article, we present the methodology of the survey, the main results and recommendations for action.

Published: November 2023

Abstract
The growing presence of activist investors in Germany challenges companies with a confrontational style and broad demands. This article analyses the Anglo-American capital market phenomenon in the context of companies’ corporate governance and their shareholder structure. We examine the valuation effects of activist campaigns using share price reactions. The short-term announcement returns surrounding activist campaigns are positive and statistically significant. The mean abnormal share price return amounts to 3.96%. The results can be attributed to a combination of transaction and information effects.
The Contribution of Each Brazilian State to the Competitiveness of the Country´S Rice Exports (1999-2021)
Authors: Fabrizio Isadora Brand , Schuh Aline Beatriz , Da Silva Rodrigo Abbade , Coronel Daniel Arruda 
Published: November 2023

Objective: This study aims to identify the contribution of each Brazilian state to the competitiveness of the country´s rice exports, through the indices of Revealed Comparative Advantage (RCA) and Relative Position (IPR), in addition to the construction of a performance matrix, according to the linear trend of the historical series of these indicators, following the model proposed by Farias and Farias (2018).

Theoretical framework: The importance of international trade is related to its ability to expand consumer markets for the population of a country, to the mitigation of internal risks through the diversification of internal markets, and to the possibility of obtaining new raw materials, technologies and new alternatives for production. Considering its relevance, commercial relations have been the object of study of economic sciences since its inception.

Methodology: Initially, the theoretical and methodological aspects necessary to obtain the Revealed Comparative Advantage (RCA) and the Relative Position (RPI) indices are detailed. Subsequently, the steps required for the construction of the performance matrix by Farias et al. (2018) for the rice sector are presented, as well as a description of the data used.

Results and conclusion: The empirical data cover the period from 1999 to 2021 and were collected in the Comex Stat database. It is noteworthy that only the first two are efficient and with a growing trend, indicating that these states have strong potential to expand their participation in the sector. The state of Acre was classified as with stable external potential, while Amazonas and Mato Grosso were classified as with stable internal potential. The other units of the federation were classified as inefficient.

Research implications: From the elaboration and analysis of this matrix, the present study contributes to deepen the discussions on the competitiveness of the Brazilian rice sector, and to elucidate the representativeness of each state for the international trade of this important commodity

Originality/value: Brazil has favorable geographic characteristics and climatic conditions to expand rice cultivation, and the sector has shown constant increases in productivity. For these reasons and considering that rice is one of the most important cereals in the world, the country could make better use of its productive potential to increase the international competitiveness of its rice sector.
Spontaneous hemopneumothorax: a rare illness with unusual presentation and etiology
Authors: El Damasy Mohamed Hussein , Khan Arshad Ali , Ba-Dheeb Ahmed , Shaigi Mootaz El 
Published: November 2023

Background:
In the acute context, spontaneous hemopneumothorax is a potentially life-threatening condition that can occur without any radiological abnormalities and may be caused by thoracic vascular aberrancy.

Case Presentation:
We discuss the case of a healthy 24-year-old man who visited our emergency department (ED) complaining of left-sided chest pain and shortness of breath. He had previously visited a tertiary care facility’s ED for the same complaint the same day and had been released following normal chest X-ray (CXR) and blood tests. His repeat CXR revealed hemopneumothorax in our department. His computed tomography scan further revealed a ruptured aberrant blood vessel which was medial to the left subclavian artery.

Conclusion:
This example case report illustrates the importance of maintaining a high index of suspicion for the probability of haemo or pneumothorax when evaluating patients who present with chest pain and shortness of breath. There must be a repeat patient examination and CXR for patients who experience prolonged chest discomfort, despite normal initial investigations. If the patient’s repeat X-rays indicate hemopneumothorax, this should leave one to ponder the likelihood that thoracic bleeding could result from vascular aberrancy.
