Experimental Matter, Unclaimed Death, and Posthumous Futures in Poe’s “Valdemar”
Authors: Ashworth Suzanne
Published: December 2023

Drawing on historical context and queer theory, this essay examines the relationship between Valdemar and his mesmerist, investigating the risks and rewards of their experimental compact. When Valdemar consents to P’s experiment, he opens himself to potential injury and certain subjugation. But he also lays claim to personhood, orchestrates his own “good death,” and thwarts disgust’s stigmatizing operations. Ultimately, however, Valdemar remains isolated and inscrutable, a tragic remnant of a queer and unlamented life.
Jorge Luis Borges’s References to Edgar Allan Poe: An Annotated Bibliography, Section 2
Authors: Esplin Emron
Published: December 2023

ABSTRACT: Throughout his distinguished career, Argentine author Jorge Luis Borges maintained a complex, reciprocal literary relationship with Edgar Allan Poe. Borges mentioned Poe in numerous articles, prologues, stories, poems, lectures, dialogues, and interviews that he wrote or participated in between the early 1920s and the mid-1980s. These pieces range from a limited number of articles and interviews that focus specifically on Poe to brief nods to Poe’s works in pieces dedicated to other authors. As part of a three-stage effort to offer future scholars a substantial guide toward the documents that demonstrate Borges’s long-term engagement with Poe’s works, “Jorge Luis Borges’s References to Edgar Allan Poe: An Annotated Bibliography, Section 2” directs readers to over eighty coauthored and collaborative pieces (including interviews and dialogues) in which Borges references Poe—providing original publication information, current bibliographic material, and annotations for each piece.
"X-ing a Paragrab": Guess what that is about if you can!
Authors: Justin Henri
Published: December 2023

ABSTRACT: Poe's last tale, built on the story of an editor failing to establish a new paper out west, has baffled commentators and been filed away as an indifferent, if a little strange, comedy—a diagnosis that runs against the fact that it stages a "devil" (Poe's long-term associate) turning O's into X's (or the poetical letter into the problematical one, Poe's art of the tale, exactly). Now, three discoveries, opening hidden depths, led to this article. 1) In the tale, Poe plays with his own surname and its central O, making his text intensely, though secretly, personal. 2) The structure of the tale points to the staging by Poe of his resignation from tale-writing. 3) At about that time, Poe was offered the editorship of a literary magazine to be printed and published in the West. Inquiries into postal matters make "X-ing a Paragrab" appear as Poe's first, indirect, and negative answer to his western correspondent. Together, with inquiries into literary matters ranging from "The Literati of New York City" in 1846 to "The Light-House" in 1849, they invite us to accompany him into his growing consciousness of his own disappearance and death.
Archipelagic Pym
Authors: Blum Hester
Published: December 2023

ABSTRACT
: Antarctica can be understood as materially continental and conceptually archipelagic. The
Narrative of Arthur Gordon Pym , this article argues, is itself archipelagic both in its
island-hopping content and in its narrative form: the continental form of the "novel" has no
integrity for Poe. In conversation with Mat Johnson's reimagining of Poe's work in his contemporary
novel Pym (2011), this article brings an archipelagic perspective to Arthur
Gordon Pym and its fantasies of whiteness. Reading Arthur Gordon Pym
and the great southern continent as archipelagic, it argues, centers what has been thought to be
scattered, minute, and peripheral into a reoriented model of mutual sustainability, reciprocity, and
loose affiliation. The disjointedness of Poe's novel can be read as a map of the contradictory
status of both Antarctica and literary whiteness in geopolitical and geophysical units of analysis.
Viewing the Southern continent as an archipelago helps to clarify (if not resolve) much of
Arthur Gordon Pym 's illogicality as a function inherent in whiteness itself.
The Method in the Madness: "The Tell-Tale Heart" and the Horror of The Human Condition
Authors: Studniarz Sławomir
Published: December 2023

ABSTRACT: This article engages with the aspects "The Tell-Tale Heart" that account for its relevance for contemporary culture and society. It will be argued that its Gothic grotesquery harbors much sense: the bizarre stunts perpetrated by its demented narrator offer insight into the modern frame of mind, and the mechanisms underlying the apparatus of a disciplinarian state, the latter analyzed here with a recourse to the ideas advanced by Michel Foucault. The article also aims to demonstrate that Poe's story was very much in tune with the changing philosophical climate that within a few decades would bring forth the revolutionary theories of Charles Darwin and Karl Marx. These new ideas would eventually lead to the collapse of the certainties grounded in religion and traditional metaphysics, leaving man alone in the vast, God-abandoned and meaningless universe, and the article contends that Poe's text exposes the tragic view of the human condition and anticipates modern existential despair.
"It Was All So White": Mat Johnson's Afrofuturist Retelling of Poe
Authors: Lavender Isiah
Published: December 2023

ABSTRACT: This article tackles the subgenre of lost race tales embedded in both SF and Afrofuturism megatexts by juxtaposing Edgar Allan Poe's only published novel, The Narrative of Arthur Gordon Pym of Nantucket (1838), with Mat Johnson's Afrofuturist retelling of Poe's novel in Pym (2011), linked through the secondary character of Dirk Peters, whose ambiguous Native American heritage in Poe's novel is made over by Johnson into an unambiguous colored man. That is to say, Johnson re-envisions Dirk Peters, racially ambiguous in Poe's novel, as Native American and something White, as a White-passing colored man. This powerful intertextual moment—this transformation of skin color—forms the crux of my argument as Johnson interrogates the meaning of race in his satirical neo-slave narrative. To accomplish this Afrofuturist reckoning for Poe, I examine the deep past of a Blackness embedded in our national literature—marked by dislocation, trauma, and White supremacy—to move forward into a different future.

Published: December 2023

Transmembrane proteins have exhibited a significant correlation with glioblastoma multiforme (GBM). The current study elucidates the roles of transmembrane protein 150A (TMEM150A) in GBM. Data on patients with GBM were collected from The Cancer Genome Atlas and Xena databases. The objective was to identify the expression levels of TMEM150A in patients with GBM, and evaluate its diagnostic and prognostic values, accomplished using the receiver operating characteristic and survival analyses. On a cellular level, Cell Counting Kit-8, Wound healing, and Transwell experiments were performed to gauge the impact of TMEM150A on cell growth and migration. The study further investigated the correlation between TMEM150A expression and immune status, along with ribonucleic acid (RNA) modifications in GBM. The findings demonstrated TMEM150A overexpression in the cancerous tissues of patients with GBM, with an area under the curve value of 0.95. TMEM150A overexpression was significantly correlated with poor prognostic indicators. TMEM150A overexpression and isocitrate dehydrogenase (IDH) mutation status were predictive of poor survival time among patients with GBM. In vitro experiments indicated that suppressing TMEM150A expression could inhibit GBM cell proliferation, migration, and invasion. Moreover, TMEM150A overexpression was associated with stromal, immune, and estimate scores, immune cells (such as the T helper (Th) 17 cells, Th2 cells, and regulatory T cells), cell markers, and RNA modifications. Therefore, TMEM150A overexpression might serve as a promising biomarker for predicting poor prognosis in patients with GBM. Inhibiting TMEM150A expression holds the potential for improving the survival time of patients with GBM.

Trend and determinants of home delivery in Gambia, evidence from 2013 and 2020 Gambia Demographic and Health Survey: A multivariate decomposition analysis
Authors: Nigatu Solomon Gedlu
Published: December 2023

Background

Home delivery is defined as is an even of pregnant women getting giving birth in a woman her home or other homes without an unskilled health professional assistance. It is continuing as public health problem since its responsible for death of women and newborn. In Gambia there is a high maternal mortality rate, which may be related to home delivery. Therefore, this study aimed to assess the trend of home delivery and identify predictors using Gambia Demographic and Health Survey (GDHS) 2013 and 2019–2020 data sets.

Methods

A Cross-Section survey was conducted based on GDHS 2013 and 2019–2020 among reproductive age group women. A total of 8607 women participated in this study. A bivariate decomposition model was fitted, and variables that had a p-value > 0.25 were dropped. Finally, variables that got a p-value of < 0.05 with 95% confidence interval (CI) in the multivariate decomposition analysis were considered as statistical significance variables in the overall decomposition.

Results

There has been a dramatic decrement in maternal home delivery in Gambia. It was 36.18% (95% CI:34.78, 37.58) in 2013 GDHS and 14.39% (95% CI:13.31,15.47) in 2019–2020 GDHS. This reduction is real because there was a change in the characteristics effect of the population and the coefficient effect some variables in the home delivery. Changes in characteristics effect of husband education, women education, rural residents, more than three antenatal cares follow up, and no problem reaching health facilities played a significant role in the reduction of home delivery. Being urban resident and women who had occupation were variables that had a positive effect on coefficient effect change.

Conclusion

In this study, the home delivery rate had steeply declined in the Gambia during the study period of the two surveys. Just above nine-tenths decrement in home delivery rate resulted because there was a change in the characteristics effect of the study participants. Enhancing more citizens to attend high school and above, narrowing the gap between rural and urban in terms of accessing health facilities, and improving the availability of infrastructure should be done.
Features of biology and population dynamics of Cephalanthera rubra (Orchidaceae Juss.) in the Sochi Black Sea region
Authors: Averyanova E. A.
Published: December 2023

Cephalanthera rubra (L.) Rich. is sporadically distributed in the Sochi Black Sea region. It occurs in the forests of the low-mountain and mid-mountain belts of the southern macroslope of the Main Caucasian Range. The number of individual populations is from two-three to a dozen individuals, usually populations are distant from each other over long distances. C. rubra can be attributed to hemiephemeroids, having spring-early summer green shoots with a period of summer-autumn-winter dormancy. The growing season lasts 3 months. Morphometric indicators of individuals of different ontogenetic states are given. The dynamics of the ontogenetic structure of the population from the area of the hornbeam forest in the vicinity of the village Illarionovka for 8 years is shown. In the ontogenetic spectra of the studied large population, the predominance of generative individuals is constant. The population is full-membered, normal type, stable. The species is self-compatible, autogamy was not revealed. The model species for pollinators seems to be Lathyrus laxiflorus (Desf.) Kuntze, which is absent from the studied population. Fruit formation in different locations does not always occur; it is absent in the studied population. Seeds of Limodorum-type, linear or fusiform, about 1.3 mm long. The species is protected in the Sochi National Park and in the Khosta Department of the Caucasian State Natural Biosphere Reserve.
Analysis of habitats and bioecological composition of communities with the participation of species of the genus Delphinium in the southeast of European Russia
Authors: Bogoslov A. V. , Shilova I. V. , Kashin A. S , Parkhomenko A. S. , Grebenyuk L. V
Published: December 2023

Between 2013 and 2020, 47 communities with seven species of the genus Delphinium were studied on the territory of 12 regions of the southeast of European Russia. The analysis of habitats by vegetation cover using the ecological scales of L. G. Ramensky showed that soils under communities with species of the genus Delpinium are often quite rich and very slightly alluvial.

D. subcuneatum communities grow in habitats with the highest moisture-meadow-steppe (moist-steppe) and wet-meadow habitats; communities of D. duhmbergii grow in less humid habitats with dry-meadow (and fresh-meadow) moisture; with dry-meadow (and fresh-meadow) and meadow-steppe (moist-steppe) humidification - communities of D. dictyocarpum, D. litwinowii, and

D. pubiflorum; in meadow-steppe (moist-steppe) humidification, communities of D. sergii. D. puniceum communities grow in the least moisture-provided habitats, with moisture ranging from dry-steppe and middle-steppe to semi-desert (desert-steppe). The biomorphological composition of communities with species of the genus Delphinium is dominated by hemicryptophytes, among which, the most numerous are tap-rooted, short-rhizomatous, and long-rhizomatous. The composition of cenomorphs reflects the confinement of communities with the majority of Delphinium species presented in the study to the forest-steppe zone, and communities with D. sergii and D. puniceum - to the steppe and semi-desert zone. In communities, the first place among trophomorphs is occupied by mesotrophs, and the second by megatrophs. The spectrum of hygromorphs is quite wide and includes species from xerophytes to ultrahygrophytes, however, xerophytes, mesoxerophytes, xeromesophytes, and mesophytes are the predominant groups most often. Judging by the predominance of heliophytes among heliomorphs, communities with all studied species of the genus Delphinium prefer open spaces. The spectrum of thermomorphs of all studied communities is dominated by mesotherms, for which the ecological optimum coincides with a moderate heat supply regime.
Materials on the synanthropic flora of the city of Khabarovsk
Authors: Burilova K. A.
Published: December 2023

The relevance of the study is due to the fact that city tram tracks, embankments and right of way are specific ecotopes that are subject to significant anthropogenic disturbances and are places of synanthropic plants concentration. We have collected 59 species from 23 families and 49 genera of flowering plants. The family spectrum is dominated by representatives of Asteraceae, the leading family of regional flora. In the generic spectrum, most genera contain one or two species each, which indicates a sufficient floristic capacity of the technogenic ecotope of tram tracks. In terms of life form, perennial herbaceous plants with underground organs survive on the tram tracks, ensuring the constant renewal of plants. Approximately the same number of alien (or adventive) and local (or native) plants have been identified by origin. As expected, alien species are confined to ruderal habitats and are characterized by wide ranges (cosmopolitan, Eurasian-North American, Eurasian types). From local species on tram tracks, plants of open habitats (forest-meadow, meadow, forest edge and slope) find suitable ecological niches.

Published: December 2023

The restoration process features of Scotch pine (Pinus sylvestris L.) growing in the Krasnoyarsk forest-steppe pine cenoses have been studied. The study purposes included the abundance and vital status investigation of viable undergrowth in pine cenoses both under control conditions and under anthropogenic impact. The restoration study results of pine regrowth by altitude groups and life condition categories are presented. The contribution of the small, medium, and large regrowth categories to the cenopopulation in various phytocenoses was assessed. The regrowth characteristics are given. It has been established that Scotch pine regrowth with “healthy” category, predominates in almost all the studied plantations. The largest amount of dried undergrowth (2.2 thousand pieces/ha) was noted in the control phytocenosis. The proportion of dry and drying regrowth in phytocenoses under anthropogenic impact ranges from 0 to 30 %, but it is 13 % at control one. However, the pine regrowth individuals’ number with “weakened” category is more than 25 %. It is concluded that at the moment the natural Scotch pine restoration under the canopy of the parent stand proceeds satisfactorily both under anthropogenic influence and in control conditions at the Krasnoyarsk forest-steppe.
A study on the conservation model of Camellia dalatensis (Camellia L., Theaceae) in Lam Dong province, Vietnam
Authors: Quach V. H. , Doudkin R. V.
Published: December 2023

Camellia dalatensis is a small tree with yellow flowers in the genus Camellia L. (Theaceae). The species is found in a single in Dalat, southern Vietnam. It is known that the Da Lat Plateau has suffered from habitat loss, degradation and fragmentation in places, and deforestation is directly impacting the range of C. dalatensis. The species is listed as Critically Endangered (CR). To provide an appropriate method for the conservation and sustainable development of this species, the study experimented with air layering and planting in their habitat (in situ). An ex situ experiment for C. dalatensis with several other species was also performed to assess their adaptability. The results showed that the average rooting time was from 3.5-4 months, the rooting rate of air layering was 78.89 % and the survival rate after planting was 96.06 %. Plants were replanted grow well in the habitat of the original population. In a new environment, the survival rate of C. dalatensis is lower than that of other species of the same genus, only 17.14 %. The surviving plants have not yet shown the ability to grow. Thus, at this time, in situ conservation method for C. dalatensis is appropriate.

Authors: Zhivotov V. V. , Ryabova K. K , Yamskikh I. E. , Stepanov N. V , Kutsev M. G.
Published: December 2023

Pulsatilla is a genus of ephemeroid grasses characterized by high morphological diversity. The study assessed the genetic polymorphism of 9 populations represented by the species P orientali-sibirica Stepanov, P turczaninovii Krylov and their hybrid P. herba-somnii Stepanov, and P. multifida G. Prizel. As a result of amplification of genomic DNA with 4 ISSR primers, 61 DNA amplicons were obtained. The overall level of polymorphism is 98.36 %. The number of amplified DNA fragments, depending on the primer, varies from 11 (17899A) to 17 (17899 B, HB12). The maximum level of genetic variability was noted for hybrid populations. The coefficient of genetic subdivision (Gst) of the studied populations is 0.4718, which indicates a high level of their differentiation. The dendrogram divides the studied populations into 3 groups, each of which is represented by a separate species, while the hybrid population is combined with P. orientali-sibirica. Phylogenetic analysis of the studied populations combines P orientali-sibirica with P multifida and P turczaninovii with P. herba-somnii. These data demonstrate the intermediate position of the hybrid population of P. herba-somnii. In the study of hybrids, ISSRS are the most informative, since they are evenly distributed across the genome and can show similarities with two parent organisms, whereas chloroplasts are inherited, as a rule, through the maternal line.
Some features of the development of the generative sphere of Juniperus deltoides in Mountain Crimea
Authors: Korenkova O. O.
Published: December 2023

To study the biomorphological features of cone berries and seeds of Juniperus deltoides, 17 sample plots were planted. By means of one-way analysis of variance, the degree of influence of abiotic and anthropogenic factors on seed productivity and seed quality was revealed. It has been established that the development of the generative sphere of J. deltoides is largely influenced by the anthropogenic load of the growing area and the amount of precipitation in the period from March to August. The size of the cone berries of J. deltoides Crimean population is smaller than in the main part of the species range. The vast majority of cone berries contain 3 seeds. Seed parameters vary insignificantly in the range from 4.4 mm to 6.0 mm (in height); from 2.3 mm to 3.2 mm (in width) and from 2.3 mm to 2.9 mm (in thickness). The weight of seeds varies quite widely from 15.9 g to 26.9 g. It has been established that almost half (47.53 %) of all J. deltoides individuals are characterized by low seed productivity. The proportion of full-grained seeds was determined, which is 1.32-26.92 %. The correlation coefficients between the indicators of the generative sphere range from 0.45 to 0.80.

Authors: Mysnik E. N
Published: December 2023

Weeds can grow both on segetal and ruderal habitats, including outside the agroecosystems of farms. Therefore, it is necessary to study their distribution not only in the fields. The purpose of the study is to identify the species composition of weeds and its features in the ruderal habitats of Gatchina (Leningrad Region). Ruderal habitats were monitored, 78 species of weeds from 62 genera and 21 families were identified. Perennial species prevailed in life expectancy. The taxonomic structure of the species composition has been established. Five families prevailing in terms of the number of species and genera are identified. Calculation of occurrence and assessment of its constancy by classes were carried out. The occurrence of the V class of constancy has 7 species, IV class - 10 species, III class - 8 species, II class - 11 species, I class - 42 species. Groups of 25 dominant and 11 concomitant species were identified. The relationship between species compositions of weeds of ruderal habitats of Gatchina and fields of the Leningrad Region was revealed - 55.56 % of weeds dominating in the fields of the region with different occurrence were registered in ruderal habitats.

At the same time, the pasture difference is recommended to be used as year-round pastures.
Genetic mechanisms of progressive evolution and speciation in plants: Gene multiplication as a way of an adequate response of the genome to the action of environmental factors
Authors: Rodionov A. V
Published: December 2023

One of the mechanisms related to the progressive evolution of plants probably is gene duplications. Paralogous and orthologous gene copies can appear in the genome either as a result of whole genome duplication (WGD), or after segmental or tandem duplications. The proportion of duplicated genes among the protein-coding genes in plant genomes is high (64 % on average), but it is several times less than would be expected if all genes duplicated during WGD were preserved - all plant genomes in that or otherwise lost some of the duplicated genes and transposons. Due to the need to respect the gene dose, for duplicated genes resulting from WGD, the rule applies: genes whose products work as part of multiprotein complexes are preserved, genes following the rule “one gene - one enzyme” prefer a monogenic existence. On the contrary, if duplicated copies of genes appeared in the genome as a result of tandem or segmental duplication, then in the first place, for the same reason, “extra” copies of the genes of the components of heteromeric complexes are lost. The role of tandem duplications in plant evolution, apparently, consists primarily in the fact that they correct the results of the distribution of alleles that remains in the genome of a polyploid or diploid as a result of processes of secondary diploidization and fractionation of neopolyploid genomes, stochastic changes in the set of alleles in comparison with stabilized (passed a long selection).
Phytocenotic characteristics and assessment of the state of the Elymus repens (L.) Gould (Poaceae) coenopopulation in the Southwestern Tien Shan
Authors: Saribaeva Sh. U.
Published: December 2023

Four coenopopulations of Elymus repens L. Gould were studied in different ecological and coenotic conditions in the mountains of the Southwestern Tien Shan. It was revealed that under anthropogenic load (grazing) the ontogenetic spectrum changes and becomes bimodal. In undisturbed phytocenoses, a left-sided ontogenetic spectrum is observed. The density of individuals in the studied cenopopulations varied from 14.9 to 9.45 ind./m2, and the ecological density was 29.8-11.81 ind./m2. According to the “delta-omega” classification, the cenopopulations of Elymus repens CP 1,4 are maturing, CP 3 and 4 are young. Existing cenopopulations are mainly located in unprotected areas. The only solution to preserve cenopopulations can be strict protection of cenopopulations.

Published: December 2023

The results of algoflora studying the Lower Irtysh and its tributary, the Tobol River, are presented. A total of 432 taxa of species and subspecies ranks were identified from 124 of 58 families and 8 departments. For the first time, a systematic list of algae is given. The greatest species and intraspecific richness were characterized by green, diatoms, blue-green (cyanoprokaryotes) and euglenic algae (93 % of the total list). Planktonic species, cosmopolitan species and beta-mesosaprobes predominated. In the phytoplankton of the mouth of the Irtysh, 368 algae taxa with a rank below the genus were registered, in the modern period in the lower reaches - 247, in the Tobol River - 192. The algae of the Lower Irtysh plankton were distinguished by a large variety of green algae and an abundance of diatoms, in the Tobol River -cyanoprokaryotes (August). The estuary section of the Irtysh River was distinguished by the highest level of quantitative development of phytoplankton, diatomaceous plankton. The modern period is characterized by the development of small-cell green algae, diatom-chlorococcal plankton. A high level of development of summer algocenosis caused by the vegetation of cyanoprokaryotes and green algae was observed in the Tobol River. The appearance of cryptomonads in the 2000s indicates organic pollution of the water masses of the surveyed rivers. The obtained materials have a certain scientific and practical value and can be used in biomonitoring.

Information about composition of the alien fraction of the flora of Baikal Siberia (BS) is given, which includes 465 species and subspecies of alien plants belonging to 282 genera and 70 families. At the same time, the same number of alien species were noted in the Irkutsk region (IO) as in the Republic of Buryatia (RB) and Zabaikalsky krai (ZK) combined. Alien plants are extremely unevenly distributed over the territory of the BS, in some areas (the north of the RB and ZK) information on the location of adventitious species is completely absent. In terms of the number of recorded adventitious species and the number of observations of them, the area Pyu 5 is the leader on the territory of which there is a large transport hub - the city of Irkutsk. The floristic data on the occurrence and distribution of alien plant species in the BS regions were updated and detailed by floristic regions according to the literature data and using the portals GBIF. org (iNaturalist Research-grade Observation), iNaturalist.org. It was found that the division of the floristic regions of the BS according to the alien element of vascular flora occurred more in the longitudinal than in the latitudinal directions, similar western regions of the Irkutsk region and eastern regions of the Republic of Belarus and West Kazakhstan were distinguished. A cluster of similarities between floristic regions of the BS was built according to the adventitious flora element.

Published: December 2023

Natural vegetation of the Western Siberia forest-steppe zone has changed dramatically under the anthropogenic pressure. The inventory for well-preserved vegetation massifs is essential for conservation of ecosystem diversity. The main goal of the study was to reveal rare and endangered plant species and communities in the forest-steppe zone of the Priobskoe Plateau. We selected 811 releves from database of Central Siberian Botanical Garden SB RAS in program IBIS 7.2 according criteria used in “Green Book of Siberia”. Rare plant communities were selected from the dataset. Their distribution is shown on maps prepared using QGIS 2.18.28. Rare communities are steppes dominated by Stipa zalesskii, Stipa lessingiana, Psathyrostachys juncea, Stipa borysthenica. They belong to the order Helictotricho-Stipetalia (class Festuco-Brometea). The pine (Pinus sylvestris) forest strips represent native vegetation and provide habitat for endangered plants. The class Pyrolo-Pinetea unites rare xero-psammophytic forests with lichens and sedges. Endemic intrazonal vegetation is represented by communities dominated by Puccinellia kulundensis and solonchak meadows with Orchis militaris and Fritillaria meleagroides (order Scorzonero-Juncetalia gerardii, class Festuco-Puccinellietea). All presented communities are vulnerable and require in accurate conservation actions.

A comparative analysis of genomes of six Hedysarum species was carried out using the rapid genomic in situ hybridization (rapidGISH) technique, which makes it possible to identify common highly repetitive DNA sequences, and also shows the patterns of their distribution on chromosomes of the studied species. Dispersed localization of genomic DNA of H. flavescens (sect. Hedysarum) was found on chromosomes of H. alpinum and H. theinum (both belonged to sect. Hedysarum). On chromosomes of H. neglectum from the section Hedysarum, clustered hybridization signals of genomic DNA of H. flavescens were observed. The localization of H. alpinum genomic DNA was found along the all chromosomes of H. flavescens and H. theinum. On chromosomes of H. grandiflorum and H. dahuricum (both from sect. Multicaulia), small clustered and dispersed hybridization signals of genomic DNA of H. flavescens and H. alpinum were found. Thus, in the studied species, common highly repetitive DNA sequences of different types of their chromosome organization were revealed. Our findings indicate the presence of common origin of the species from the sections Hedysarum and Multicaulia with different degree of their relationship.
Dynamic Pricing Strategy, Impacts of Fair Pricing Perception on Consumer Reaction
Authors:   , Sevinj Omarli
Published: December 2023

This research examines the relationship between dynamic pricing, fair pricing perception, and willingness to buy. The theoretical contribution of this research is to provide a conceptual framework and empirical evidence for understanding the complex relationships between constructs. The study also examines the moderating effect of price position, internal reference price, price sensitivity, industrial norm, brand image on the relationship between dynamic pricing and fair pricing perception. In frame of the research, 387 undergraduate students have been surveyed about their airline ticket buying behaviour. Dynamic pricing strategies and price positions were applied as stimuli in a quasi-experimental setting. Results show that the effect of dynamic pricing strategies has a significant effect on perceived fair pricing and, through this, on the willingness to buy. It was investigated that price position moderates the association between dynamic pricing strategy with decreasing trend and fair pricing perception. In the case of a relative higher market price, this effect is stronger. The brand image is also a key concept in marketing. It has an influence on consumers attitude towards the brand and therefore effects the information the consumers select and let it or, on the other hand, filter out during the process of perception. The current study supported that the negative effects of dynamic pricing are weaker when the brand image is positive in the mind of consumers. Norms could heavily effect consumer behavior and its influence has been revealed in several studies. However, studies investigating the moderation role of industry norm in dynamic pricing context are rare. As this moderation effect was examined between the subdimensions of dynamic pricing and fair pricing perception, the outcome of the research is also novel to the literature. Limited research has been conducted on consumer perceptions of price fairness in the context of dynamic pricing. Examining the relationship between perceived price fairness and consumer purchasing propensity in the context of dynamic pricing is the purpose of the present study. The results of the study build upon prior research while also presenting contradictory findings. The findings cast light on the formation of price fairness perceptions in dynamic pricing and the influence of these perceptions on consumer purchase intent. This study contributes in two ways to the literature on price fairness. First, it combines two significant antecedents - price volatility and price change trends - with an outcome dimension, namely purchasing propensity, into a single conceptual model. Second, the research identifies potential moderator variables, including price position, consumer price sensitivity, industry norm, and brand image.
Network Analysis of the Financial Sector: A Comprehensive Perspective with Adaptive Joint LASSO Method
Authors:   , Badics Milán Csaba
Published: December 2023

The emergence of systemic risk from the 2008 Global Financial Crisis (GFC) and the recent energy market shocks following the COVID-19 pandemic and the onset of the Russo-Ukrainian war highlighted the importance of understanding shock spillovers for policymakers and academics alike. Specifically, shock transmissions in financial network settings warrant attention to support regulatory or policy interventions for effectively mitigating or preventing the transmission of systemic risk. The thesis focuses on this important topic from various angles to answer the following questions: • How can machine learning techniques help to improve financial network studies, the analysis of high dimensional time series? • How can structural changes in financial networks efficiently examined using event analysis framework? My thesis provides methodological and conceptual contributions to financial network analysis. The contribution of my thesis to the existing literature is threefold: 1. I propose a new regularization method, the adaptive joint least absolute shrinkage and selection operator (AJ LASSO). The innovation in this method is that it accounts for possible sparsity both in the coefficient and the covariance matrix of the estimated Vector autoregressive (VAR) model. The method is especially suitable for high-dimension network analysis, where parameter estimation is a critical issue. 2. I extend the Diebold-Yilmaz (DY) framework with an event study tool to facilitate an in-depth analysis of the contagion channels during critical local and global shocks in financial networks. Integrating a moving-block bootstrap method (MBB) into the framework, I can investigate how the observed shocks transform the financial networks. 3. My conceptual contribution is that I characterize and analyze illiquidity networks. The liquidity concerns are globally recognized and the focal point of the newly revised Basel IV regulatory guidelines; thus, intuitively and from a regulatory perspective, illiquidity spillover analysis in the financial sector is valuable. I analyze the illiquidity connectedness of financial institutions (FIs) and show that the illiquidity network better tracks the dominant shock transmitters in the system during financial turmoil than the volatility-based networks. I show that the DY framework extended with the MBB method is a powerful tool to identify troubled financial institutions and contagion channels.

Az 1867. évi kiegyezést követően Magyarországon jelentős gazdasági fejlődés indult meg. A mintegy 50 éves időszak alatt a magyar gazdaság virágkorát élte: megindult az iparosodás, növekedett a kereskedelmi forgalom és gyorsan fejlődött számos ágazat, mint például a vendéglátás. Pécsett, a Dél-Dunántúl legnagyobb városában, az átalakulás fontos része volt, hogy a hagyományos vendégfogadók rendszerét a XX. század elejére felváltotta a modern szállodaipar. Az újonnan felépített szállodák tulajdonosai pécsi iparosok, nagykereskedők voltak, akik bérbe adva működtették vállalkozásukat. A tanulmány azt vizsgálja, hogy melyek voltak a korszak szállodaiparának legfontosabb elemei, kik voltak a tulajdonosok, s a létrejött szállodák milyen minőséget képviseltek. Az elemzés kimutatja, hogy a modern vállalkozások eredményeképpen Pécsett a XX. század elejére egy országos mércével is jelentősnek mondható, minőségi szállodakapacitás jött létre, amelynek épületei még ma is a városkép meghatározó egységei.
