Authors: TIERRA TIERRA NANCY PATRICIA , CHAVEZ VELASQUEZ CARLOS RENATO , SOLÍS BARRIONUEVO ALBERTO PAUL
Published: January 2023

La pandemia del COVID-19 ha causado una crisis sin precedentes al sector turístico a nivel mundial, siendo los servicios de hospedaje uno de los más afectados a causa de las restricciones y el miedo a viajar de los turistas, ya que ahora exigen una mayor seguridad en los establecimientos y asocian la crisis sanitaria a la ambiental. Por ello surge la necesidad de establecer planes internos de gestión e innovación más sostenible en los hoteles, de manera que este artículo propone un plan de negocios con enfoque de sostenibilidad que se refuerza con la incorporación de indicadores que evalúan criterios de buenas prácticas y responsabilidad social empresarial para diseñar una nueva oferta de hospedaje que se pueda transferir a otros establecimientos de distintos destinos. Este estudio de caso se ha realizado en la cadena GH Hoteles en la ciudad de Riobamba-Ecuador durante el año 2019 y se presenta como una adaptación para la post pandemia. Metodológicamente se evaluaron 196 indicadores de Buenas Prácticas (BP) y 384 indicadores de Responsabilidad Social Empresarial (RSE) sobre criterios ambientales, socioculturales y de gestión, para después resolverlos y construir así una nueva oferta más sostenible para los hoteles que contribuya a un turismo más responsable desde el punto de vista ambiental, económico y sociocultural después de la pandemia.

La realidad del turismo en Manabí (Ecuador) y la economía circular como potencial de sostenibilidad turística
Authors: ZAMBRANO SANTOS ZITA LUCÍA , NAVAJAS ROMERO VIRGINIA , CEULAR VILLAMANDOS NURIA
Published: January 2023

Después del terremoto 2016 las provincias costeras de Manabí y Esmeraldas fueron azotadas por un fenómeno telúrico que afectó en gran proporción al sector turístico, lo que se ha ido acentuando hasta la actualidad por la presencia pandémica que ha puesto en serios riesgos la economía de este sector. El presente estudio analiza la operatividad de la Agenda de Reactivación (AR) propuesta por el Gobierno ecuatoriano a raíz del terremoto 2016, enfocando la economía circular como propuesta de sostenibilidad en los servicios complementarios del turismo, particularmente en hoteles y restaurantes. La metodología utilizada es el análisis comparativo de las metas propuestas en la AR y los logros alcanzados al 2019, además de la interpretación de la intervención de la economía circular como modelo de gestión en el marco de las investigaciones del Observatorio Ciudadano de Manabí y el uso de la economía circular como potencial de gestión para la reutilización de desechos sólidos en Portoviejo-Manabí. Como principales hallazgos se advierte que los alcances logrados en el sector turismo no se ajustan a lo planificado en la AR y que la ejecución de los proyectos no ha sido satisfactoria de acuerdo con las metas propuestas, además de la ausencia de articulación interinstitucional en la gestión de los mismos. Por otro lado, en la ciudad de Portoviejo se producen diariamente entre 50 y 100 kg de residuos sólidos en hoteles y restaurantes, de manera que la economía circular debería de considerarse como un mecanismo de sostenibilidad ambiental mediante la reutilización de los mismos, entre otras acciones.

Published: January 2023

Cet article est conçu pour défendre l’idée que le Congo ainsi que d’autres pays similaires doivent impérativement redéfinir le tourisme pour une nouvelle tendance touristique afin de favoriser un développement  local, régional/Etatique et international. Cet article est alors un recueil de propositions (pistes de solutions) qui s’impose au Congo pour un nouveau paradigme du tourisme. De formation géologique et d’expérience associative ainsi que professionnelle axée sur la culture, je suggère au Congo de redéfinir le tourisme Congolais en créant un « Géo-parc nommé  Géoparc-Loango (GéoLoango) » qui prendra en compte la valorisation, la préservation, la promotion du patrimoine  naturel, Biologique/Géologique, et  Culturel pour un vrai développement touristique adéquat, efficace et pertinent.

“No man is an island unto himself” – John Donne
According to the World Health Organization, health is “a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity.” Our healthcare industry, public behaviors, and environment have grown exponentially with digital technologies in the era of the 4th industrial revolution. Due to rapid digitalization and easy availability of the internet, we are now online round the clock on our digital devices, leaving behind digital traces/information. These digital footprints serve as an increasingly fruitful data source for social scientists, including those interested in demographic research. The collection and use of digital data (quantitative and qualitative) also present numerous statistical and computational opportunities, further motivating the development of new research approaches to address health issues. In this paper, we have described the concept of digital well-being and proposed how we can use digital information for good health.

ANN Based Estimation of Pore Pressure of Hydrocarbon Reservoirs - A case study
Authors: Kianoush Pooria , Mohammadi Ghodratollah , Hosseini Seyed Aliakbar , Khah Nasser Keshavarz Faraj , Afzal Peyman
Published: January 2023

In seismic methods, pore pressure is estimated by converting seismic velocity into pore pressure and calibrating it with pressure results during the well-testing program. This study has been carried out using post-stack seismic data and sonic and density log data of 6 wells in one of the fields in SW Iran. While an optimum number of attributes is selected, the General regression (GRNN) provides higher accuracy than Back Propagation (BPNN) at the initial prediction stages. However, Acoustic Impedance (AI) is the most applicable seismic attribute used as root and reverses AI for estimating P-wave and density. Using a set of attributes can train the system to estimate the property. The correlation coefficient of actual and predicted P-wave using an AI seismic attribute has been calculated as 0.74 and the multi-attribute technique as 0.79. Also, density and three attributes reach from 0.57 to 0.60, which shows a better relationship between seismic attributes and density. After determining optimum layers with the principal components analysis (PCA), formation pressure was modeled with the feed forward-backpropagation (FFBP-ANN) method. Five information layers, including gamma, Vp, AI, density, and overburden pressure, have the most linear convergence with the initial pressure model and are used to modify the ANN model of effective pressure.

Published: January 2023

Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is an invasive alien pest native to the Americas, and it was introduced in the state of Karnataka, India in the year 2018. They cause severe economic damage to the maize crop, which significantly decreases the quality and quantity of the crop's yield. The microbiota of fall armyworm could play important roles in their growth, development and environmental adaptation to their host plants or animals and not much is known about the microbiota of FAW in India. Even though bacterial communities in S. frugiperdaare inadequately studied, therefore, a study was undertaken on the microbial communities associated with the gut of S. frugiperda collected randomly from twelve different locations in the eastern part of India under laboratory conditions. The results revealed that the two bacterial phyla, namely, proteobacteria and firmicutes, were predominantly present in the larval gut of S. frugiperda. However, analyses at the genus level revealed that despite the high genus-level diversity between samples, there were 9 different genera observed. Interestingly, we found two bacterial genera, i.e., Kluyvera and Yokenella, which may be new findings from the eastern part of India and were not reported earlier from any other countries. On the other hand, analyses at the species level revealed that a total of thirty-three (33) species were found from the 12 samples of S. frugiperda collected from different locations. Among the 33 species, Enterococcusgroup genera were most abundant across the FAW gut samples collected, followed by Klebsiella sp. and Enterobacter sp. and a small proportion of Raoultella, Citrobacter, Leclercia and Pantoea.

Published: January 2023

Histone lactylation has been reported to involve in tumorigenesis and development. However, its biological regulatory mechanism in endometrial carcinoma (EC) is yet to be reported in detail. In the present study, we evaluated the expression of global lactylation in EC tissues by immunohistochemistry and western blot, and it was elevated. The non-metabolizable glucose analog 2-deoxy-d-glucose (2-DG) and oxamate treatment could decrease the level of lactylation so as to inhibit the proliferation and migration ability, induce apoptosis significantly, and arrest the cell cycle of EC cells. Mechanically, histone lactylation stimulated USP39 expression to promote tumor progression. Moreover, USP39 activated PI3K/AKT/HIF-1α signaling pathway via interacting with and stabilizing PGK1 to stimulate glycolysis. The results of present study suggest that histone lactylation plays an important role in the progression of EC by promoting the malignant biological behavior of EC cells, thus providing insights into potential therapeutic strategies for endometrial cancer.

Introduction

AL amyloidosis has become a common secondary cause in elderly male patients presenting with nephrotic syndrome. Daratumumab-CyBorD regimen is approved as the standard first-line regimen for AL-amyloidosis. We aim to analyze the prognosis of patients treated with bortezomib-based regimen and other alternative regimens.

Method

We retrospectively collected the baseline and follow up data of newly diagnosed AL amyloidosis patients. Hematological and renal response rate were compared among different regimens and overall survival and renal survival were analyzed. Subgroup analysis of Mayo stage III patients was also performed.

Results

72 cases were included, 48.6% of whom had cardiac involvement. Overall response rate in patients treated with bortezomib-based regimen was 67.4%, including 27.9% complete response (CR). Renal outcomes such as proteinuria response rate and incidence of end stage renal disease (ESRD) were not different between bortezomib and thalidomide-based therapy.Median follow up for whole cohort was 22 months,and 13(18.1%) patients died at the end of follow-up, while 7 patients(9.7%) progressed to dialysis. Median overall survival (OS) was not reached in both regimens and 1 year survival rates were 90.4% and 80.0% respectively in bortezomib and thalidomide based therapy(P = 0.127). Patients treated with bortezomib-based treatment had longer organ deterioration progression-free survival (MOD-PFS).There was no difference in response rate and OS between patients treated with cyclophosphamide, bortezomib,dexamethasone(CVD) and bortezomib, dexamethasone (VD). Mayo stage III patients who were treated with VD regimen had longer OS compared with TD or CTD regimen.

Conclusion

Bortezomib-based regimen had high efficacy in promoting rapid hematologic responses and reducing the risk of major organ deterioration in AL amyloidosis, which was also effective among patients with cardiac insufficiency. Addition of cyclophosphamide into VD regimen could not further improve the overall remission or survival of AL amyloidosis.

Authors: Ye Lintao , Zou Changjun , Xu Hangbin , Lin Chuchao
Published: January 2023

In recent years, for the effect of image reconstruction, the research of single image Super-resolution (SISR) using Convolutional Neural Networks (CNN) has made significant progress, and is superior to traditional methods. Aiming at improving network performance, residual connection plays a key role in these CNN-based methods. With the increase of the depth of these CNN-based networks, the residual features more aggregate the information of multiple different levels of the input image, which is more advantageous for the reconstruction of image details. However, inmost deep CNN-based SR models, the hierarchical features of the original Low-resolution (LR) image are not fully utilized. In order to solve this problem. We propose Residual Dense Feature Aggregation Block (RDFAB). Where RDFAB is the unit of residual blocks and the features extracted from each residual block are aggregated to the end of the module. As a result, RDFAB is able to produce more representative features. To further strengthen the effectiveness of RDFAB, we propose a multi-scale feature aggregation (MFA) framework, and our final multi-scale residual dense feature aggregation network (MRDFAN) combines RDFAB and MFa together with the addition of skip connections.Comprehensive experiments demonstrate the necessity of the MF A framework and the advantages of MRDFAN over the state of the art SISR methods.
COVID-19 vaccination strategies in settings with limited rollout capacity: a mathematical modelling case study in Sierra Leone
Authors: Bilgin Gizem Mayis , Lokuge Kamalini , Jabbie Ernest , Munira Liza , Glass Kathryn
Published: January 2023

Background
COVID-19 vaccine coverage in low- and middle-income countries continues to be challenging. As supplies increase, coverage is increasingly becoming determined by rollout capacity.
Methods
We developed a deterministic compartmental model of COVID-19 transmission to explore how age-, risk-, and dose-specific vaccine prioritisation strategies can minimise severe outcomes of COVID-19 in Sierra Leone.
Results
Prioritising booster doses to older adults and adults with comorbidities could reduce the incidence of severe disease by 21% and deaths by 32% compared to the use of these doses as primary doses for all adults. Providing a booster dose to pregnant women who present to antenatal care could prevent 39% of neonatal deaths associated with COVID-19 infection during pregnancy. The vaccination of children is not justified unless there is sufficient supply to not affect doses delivered to adults.
Conclusions
Our paper supports current WHO SAGE vaccine prioritisation guidelines (released January 2022). Individuals who are at the highest risk of developing severe outcomes should be prioritised, and opportunistic vaccination strategies considered in settings with limited rollout capacity.
Deception Detection using Random Forest-based Ensemble Learning
Authors: Bu Kun , Ramachandran Kandethody
Published: January 2023

The purpose of this work is to detect people lying using different ensemble machine learning algorithms to conclude a better classification model through comparison. Random Forest (RF) did an efficient work while dealing with both classification and regression problems; In this paper, we proposed a Random Forest-based ensemble learning, which is the combination of RF with SVM, GLM, KNNs, and GBM to improve the model performance. The data set that we used to fit into the machine learning models is Miami University Deception Detection Database (MU3D). MU3D is a free resource containing 320 videos of Black and White targets, female and male, telling truths and lies. We fit the MU3D video level data set into Random Forest-based ensemble learning models, which includes RF + SVM.Linear, RF + SVM.Poly, RF + GLM, RF + KNNs, RF + GBM (Stochastic Gradient Boosting) and RF + WSRF (Weighted Subspace Random Forest). As a comprehensive comparison of the model performance, we conclude our new combination of algorithms performs better than the traditional machine learning models. Our contribution in this work provides a robust classification method which improves the predicted performance while avoiding model overfitting.

Published: January 2023

Background: Hand-foot-and-mouth disease (HFMD) poses a global pediatric public health problem. There is no effective cure, so prevention and control of HFMD appears crucial. Spatiotemporal aggregation analysis allows exploration of disease occurrence, epidemic pattern, transmission rules, etiology and transmission risk, giving a basis for disease prevention and control, what information can provide in terms of the epidemiological characteristics of HFMD in Dali?
Objectives: This study aimed to Combine with the spatiotemporal aggregation analysis, which augment scientific reference and provide theoretical guidance for prevention and control research into HFMD and other epidemic diseases.
Methods: Infectious disease surveillance data and pathogen test results from the Dali Center for Disease Control and Prevention relating to HFMD were collated. An approach focusing on descriptive epidemiology and spatiotemporal clustering was adopted.
Results: A total of 49 093 HFMD cases were reported in Dali between 2013 and 2021, giving a mean annual incidence of 150.90/100 000 and 2 793 out of 4 634 samples tested positive (60.27%). Annual incidence showed significant differences between years (Χ² = 2 614.63, p < 0.001) with the majority of cases occurring during the summer. Diaspora children (n = 32 374, 65.94%) aged between 0 to 6 years old were predominantly affected and incidence rate varied by sex with males more likely to be infected (Χ² = 755.65, p < 0.001). Yongping(437.43/100 000), Binchuan(344.78/100 000) and Dali City (294.10/100 000) showed the highest incidence rates with those of adjacent areas being relevant. Clusters were more likely to occur between 4/1-7/31 and 10/1-12/31 and data were gathered from Dali City, Yangbi, Binchuan, Yongping, Yunlong, Nanjian, Weishan and Heqing.
Conclusions: HFMD in Dali was concentrated in the summer and predominantly affected preschool children. The highest incidences were found in Yunlong, Binchuan and Dali City. Incidence rates were correlated in time and space with dominant pathogens being CA16 and other EVs. The current data relating to the trend of the epidemic indicates that Dali public health departments may benefit from timely prevention and control measures.

Published: January 2023

Endoscopic submucosal dissection (ESD) is an accepted treatment for early esophageal cancer and precancerous lesions, but resection of a large mucosal area often leads to postoperative esophageal stricture. Biomaterials provide a new option for the treatment of post-ESD ulcers. In this study, we developed a well-defined ammonolysis-based tetra-armed poly (ethylene glycol) (Tetra-PEG) hydrogel and investigated its efficacy and related mechanisms for preventing esophageal ESD-induced stricture in a porcine model. In terms of material properties, Tetra-PEG hydrogel present great biocompatibility, great capability to retain moisture, strong tissue adhesion and high mechanical strength. Then, six domestic female pigs were randomly divided into PEG (n = 3) and control groups (n = 3). A 3/4 of the esophageal circumference ESD was performed in all pigs. In PEG group, Tetra-PEG hydrogel was easily delivered via endoscopy and adhered to the ulcer bed tightly. Compared to control group, Tetra-PEG hydrogel accelerated esophageal ulcer healing at an early stage with enhanced epithelium regeneration, milder inflammation and lesser fibrosis by regulating TGF-β/Smad2 signaling. Taken together, our findings reveal Tetra-PEG hydrogel is a promising and attractive candidate for preventing the formation of fibrotic stricture in the process of esophageal ESD-induced ulcer repair.
The novel fault diagnosis method of gearbox based on FBEWT and manifold regularization ELM
Authors: Wang Ke , Qin Fengqing
Published: January 2023

The novel fault diagnosis method of gearbox based on FBEWT and manifold regularization ELM is proposed to obtain excellent fault diagnosis results of gearbox in this paper. A new feature extraction strategy based on Bessel series expansion-based empirical wavelet transform Fourier (FBEWT) is used to capture the key non-stationary features of the vibrational signal of gearbox, and significantly improve the diagnosis ability of gearbox. The ELM with manifold regularization is proposed for fault diagnosis of gearbox. In order to outstand the superiority and stability of the proposed FBEWT and manifold regularization ELM, the balanced dataset and unbalanced dataset, respectively, are used. The experimental results testify that FBEWT-MRELM are more superior and stable than EWT-MRELM, and EWT-ELM regardless of balanced dataset and unbalanced dataset.
Earthquake disaster simulation of regional bridges based on nonlinear dynamic time history response analysis
Authors: Qian Ji , Yang Jipeng , Xia Ye , Yan Yexiang , Zhou Jianting
Published: January 2023

As the hub of the traffic network, the rapid assessment of the damaged state of bridges after earthquakes is of great significance for post-disaster rescue. The traditional vulnerability-based method can only provide the probability of different damage states of structures under different earthquake intensity indicators, which confuses the selection of post-disaster rescue routes. Therefore, based on nonlinear dynamic time history response analysis, this paper proposes a technology for earthquake disaster simulation of regional bridge groups and rapid assessment of post-earthquake damage state. First, the surface seismic response is calculated based on the regional geological borehole data obtained from the previous investigation; Second, the simplified computational mechanical model of the regional girder bridge is extracted to achieve standardized and modular data input and response analysis; Finally, the damaged state of the bridge is evaluated quantitatively based on the selected component damage index. Eighty-five bridges in a specific area are considered an example to verify the proposed method. The results show that the proposed method has high calculation efficiency and can consider the site characteristics and structural design parameters. Also, the calculation results can better reflect the actual earthquake damage distribution, providing strong technical support for post-disaster rescue.

Published: January 2023

Objectives

To assess outcomes of bilateral single-session percutaneous nephrolithotomy (PCNL) with minimally invasive technique in pediatric population. Patients and

methods

Children who were treated with minimally invasive bilateral single-session PCNL from August 2015 to July 2021 were analyzed. Minimally invasive PCNL in this study included miniPCNL (12-16-Fr) and Microperc (4.8-Fr). Patient demographics, stone and operative characteristics, stone-free rate (SFR) and complication rate (CR) were detailed and compared. Independent predictors for operation time, irrigated fluid volume, postoperative hospital stay and postoperative complication were determined.

Results

Forty-five children (including 12 infants) with mean stone burden of 3.2 cm were enrolled, among whom the male-to-female ratio was nearly 1.5:1. SFR was 93.3% and overall CR was 53.3% (Clavien grade 1 + 2, 46.7%). SFR were favourable with different sizes of PCNL. Self-limiting hematuria represented the most common complication (33.3%), especially with miniPCNL. Stone burden was the only independent predictor for operation time (p<0.001) and postoperative complication (p = 0.008). Children with older age (p = 0.009), higher body mass index (p = 0.016) or higher stone burden (p<0.001) received larger irrigated fluid volume. Microperc was associated with less irrigated fluid volume (p = 0.001). Children with overall complications (p<0.001), especially Clavien grade 3 complications (p = 0.004) spent prolonged postoperative hospital stay.

Conclusion

Bilateral-Microperc was a preferred option for children with lower stone burden or younger children. Bilateral single-session PCNL is a feasible, effective and safe procedure for pediatric complex nephrolithiasis, and it could be a surgical option for experienced urologists.
Real-time Gesture Detection in Complex Multi-person Scenarios

Published: January 2023

Lacking of gesture datasets for the scenarios with multi-person, gesture detection for multi-person is generally used two-stage schemes, thus leading to high computation and time cost. In this paper, we propose a method to automatically create a multi-person gesture dataset, which can quickly generate gestures with annotation information without manual annotation in complex scenarios. Afterwards, we treat different gestures as different categories and use a one-stage approach to detect and classify all the gestures in multi-person scenarios in a single run.
Among the popular object detection backbones, the one that performs best on our dataset is pruned for the purpose of computational efficiency, knowledge distillation is further performed on the pruned
model to mitigate the accuracy decline caused by pruning, and focal loss function is optimized for improving model performance.
Experiments show that our approach significantly reduces the processing time for gesture detection in multi-person scenarios, while just slightly sacrificing the prediction accuracy. In a multi-person scenario with ten hands, the inference time of our algorithm is only 12 ms, outperforming the off-the-shelf methods by at least 4.3 times.

Published: January 2023

Germline genetic testing is an increasingly important component of treatment decision-making for clinicians and patients with breast cancer. To address increased demand and expedite access to genetic testing for these patients, the Parkville Familial Cancer Centre (PFCC) in Victoria, Australia, implemented a breast mainstream genetic testing program. The program educates and supports breast cancer specialists to provide eligible patients with pre-test information, gain consent, and arrange genetic testing during their routine cancer appointments. This study aimed to explore breast cancer specialists’ experiences and opinions of the education program and of facilitating mainstream genetic testing for their patients. Specialists who had attended the mainstream genetic testing education were invited to complete an online survey about the training provided through the education program and their experience of deploying mainstream genetic testing in their practice. Descriptive statistics were compiled, and content analysis used for open text responses. Forty-five breast cancer specialists (breast surgeons, medical oncologists, radiation oncologists and breast care nurses) responded (45% response rate). Most participants had discussed (87%) and consented (80%) patients for mainstream genetic testing. Most specialists (81%) rated their confidence levels as high or very high for consenting patients to mainstream genetic testing. The majority (89%) indicated that they believed mainstream genetic testing should be part of their role and felt well supported by the PFCC (90%). This research demonstrates that the breast cancer specialists were satisfied by the education they received and the PFCC has successfully integrated mainstream genetic testing for breast cancer patients.

Euphorbia saratoi (= E. podperae, E. pseudovirgata auct., E. virgata var. orientalis, E. virgultosa) – in Mitteleuropa und Nordamerika ein Neophyt unklarer Herkunft
Authors: Reichert Hans , Gregor Thomas , Meierott Lenz
Published: January 2023

Eine Euphorbia-Art, die im 19. Jahrhundert nach Mitteleuropa und Nordamerika einwanderte, wurde zunächst für E. esula oder E. virgata gehalten. Um die Mitte des 20. Jahrhunderts setzte sich die Auffassung durch, es handle sich um eine Hybride zwischen den genannten Arten, wofür E. ×pseudovirgata Verwendung fand. Später wurde die Pflanze als eigenständige Art, E. pseudovirgata, betrachtet. E. pseudovirgata (= E. virgata var. pseudovirgata) ist jedoch ein Synonym von E. virgata. Als ältester Name für die somit irrtümlich als E. pseudovirgata bezeichnete Sippe wurde E. saratoi ermittelt; Synonyme sind E. virgata var. orientalis, E. esula f. linariifolia, E. podperae und E. virgultosa. E. saratoi stimmt – nach Zählungen in Deutschland – in der Chromosomenzahl mit E. esula überein (2n = 60), E. virgata ist durch eine somatische Chromosomenzahl von 2n = 20 deutlich verschieden. Die Blätter von E. saratoi und E. virgata weisen (meist ungleich starke) Palisadenparenchyme an der Ober- und Unterseite auf (annähernd äquifazialer Blattbau) und damit einhergehend amphistomatische Spaltöffnungsverteilung. Die Palisadenparenchyme sind bei E. saratoi einschichtig, bei E. virgata überwiegend zweischichtig. E. esula unterscheidet sich von beiden Arten durch bifazialen Blattbau und annähernd hypostomatische Spaltöffnungsverteilung. Die Form der Blätter ist variabel, aber es gibt deutliche Tendenzen. E. saratoi hat Blätter mit in weiten Bereichen parallelen Blatträndern, bei E. esula liegt die größte Blattbreite in der apikalen Hälfte. E. virgata besitzt Blätter mit der größten Breite im basalen Drittel. Die Cyathien haben bei E. esula auf der Innenseite Haarleisten, bei E. saratoi und E. virgata fehlen diese. Die Septalschuppen in den Cyathien sind bei E. esula weit herab behaart, bei E. saratoi und E. virgata nur an der Spitze. Bis jetzt lässt sich die Pflanze mit Sicherheit nur in Teilen Europas und Nordamerikas als Neophyt einstufen. Das ursprüngliche Verbreitungsgebiet kann nicht verlässlich angegeben werden.
Carex liparocarpos in Deutschland – ein Erstnachweis und viele Fragen
Authors: Welk Erik , Oesau Albert
Published: January 2023

Carex liparocarpos s. str., die Glanzfrüchtige Segge, wurde durch Albert Oesau im NSG Lennebergwald bei Mainz erstmals sicher für Deutschland nachgewiesen. Der Neufund wird hier areal- und vegetationskundlich eingeordnet und diskutiert. Dabei werden zahlreiche interessante Fakten, aber auch Fragen und Unklarheiten aufgeworfen. Die Art ist nah verwandt mit C. supina, mit der sie oft verwechselt wurde und wird. In der Ukraine ist die Abgrenzung zu C. schkuhrii (Syn. C. liparocarpos subsp. bordzilowskii) unklar. Mit C. turkestanica kommt der engere Verwandtschaftskreis als Subsektion Nitidae bis in mittelasiatische Gebirge vor. Das Hauptareal der Art wird – genauer als bisher – als submediterran-westpannonisch charakterisiert. Azonale Arealbereiche sind durch südatlantische, nordadriatische und pontische Dünenregionen repräsentiert. Mediterran-alpine, isolierte Vorposten wurden in Nordafrika bis auf ca. 30° n. Br. gefunden. In Frankreich gibt es wenige, bis auf ca. 50° n. Br. vorgeschobene, isolierte Vorposten, von denen viele gefährdet bzw. erloschen sind. C. liparocarpos s. str. besiedelt vorrangig neutral-basische Sandsteppen-, Dünen-, Fluss-Schotter- und Felserosionsstandorte und ist u. a. typisch für die Festucetalia vaginatae, Festucetalia valesiacae, Artemisio albae-Brometalia erecti, Scorzoneretalia villosae, Trachynietalia (Brachypodietalia) distachyi, Ononidetalia striatae und Artemisio-Koelerietalia. Auf Grundlage der gewonnenen Gesamtübersicht zu Verbreitung und Habitatbindung wird der Einbürgerungsstatus des Neufundes bewertet. Nach dem derzeitigem floristischen Kenntnisstand erscheint eine neophytische Einschleppung wahrscheinlich – ist aber nicht zwingend anzunehmen, da der Wuchsort in einem für die Art vegetationskundlich nahezu perfekt typischen Lebensraum liegt, der allerdings floristisch gut durchforscht ist.

2019 wurden Viola riviniana, V. reichenbachiana und ihre Hybride, Sanguisorba officinalis, Koeleria und Scrophularia umbrosa s. l. durchflusszytometrisch untersucht. Bei Viola wurde neben den Ausgangsarten auch mehrfach die Hybride Viola ×bavarica nachgewiesen. Pflanzen mit kurzem, teilweise blauem Sporn erwiesen sich aber meist als V. riviniana. Bei Sanguisorba officinalis fanden wir nur oktoploide (8x) Pflanzen. Die ähnlichen Koeleria macrantha und K. pyramidata unterschieden sich sehr deutlich im relativen DNA-Gehalt, K. macrantha erwies sich als tetraploid (4x), K. pyramidata als wahrscheinlich dekaploid (10x). Das einzige deutsche Vorkommen von K. vallesiana ist hexaploid (6x) und gehört damit zur Nominatunterart. Bei K. glauca konnten wir in Deutschland Diploidie (2x) bestätigen. K. grandis hat ähnliche relative DNA-Gehalte wie K. pyramidata und dürfte ebenfalls dekaploid (10x) sein. Einzelne Messungen bei Scrophularia bestätigten Zuordnungen zu S. neesii und S. umbrosa. Bei Sanguisorba und Viola waren in vielen Fällen Messungen nicht erfolgreich.
Arabidopsis arenosa auf Rügen: Erweiterung des Areals diploider Vorkommen auf die Flora Deutschlands
Authors: Schröder Christof Nikolaus , Hojka Jakub , Schmickl Roswitha E.
Published: January 2023

Die Sandschaumkresse Arabidopsis arenosa kommt in zwei Zytotypen vor, dem diploiden und dem tetraploiden. Für Deutschland waren bisher keine diploiden Populationen sicher nachgewiesen und untersucht. In dieser Studie zeigen wir, dass sich das Verbreitungsgebiet diploider A. arenosa auf die deutsche Ostseeküste erstreckt. Auf der Ostseeinsel Rügen fanden wir drei Metapopulationen im hochdynamischen Habitat der Sand- Steilabbrüche, bei dessen Besiedlung durch A. arenosa Biokrusten ("Biological soil crusts") und "Insel-Schollen" eine Rolle zu spielen scheinen. Funde auf ruderal getönten Standorten waren selten, mit nur einer Metapopulation. Wir bestimmten das DNA-Ploidieniveau der Proben durchflusszytometrisch, und es zeigte sich, dass alle gesammelten Proben diploid waren. Von drei Metapopulationen wurden Aussaaten kultiviert und die Pflanzen morphologisch untersucht. Hierbei zeigte sich, dass eine wenig verzweigte, hohe Wuchsform vorherrscht, die eher untypisch für A. arenosa ist.

Weitere Nachträge und Korrekturen zur Liste der in Deutschland vorkommenden Gefäßpflanzen werden zusammengestellt und kommentiert. Sechs Taxa, zumeist aus sogenannten kritischen, überwiegend agamospermen Gattungen, sind neu für Deutschland. Mehrere Sippen müssen hingegen gestrichen werden, weil sie in Deutschland keine etablierten Vorkommen aufweisen. Für eine Reihe von Taxa werden Namensänderungen empfohlen, da die auf molekularphylogenetischen Untersuchungen beruhende Neugliederung der Gattungen nunmehr abgesichert erscheint. Zusätzlich werden von Günter Gottschlich Validierungen von 18 Namen in Hieracium s. l. vorgenommen.

Authors: Hroudová Zdenka , Gregor Thomas , Zákravský Petr
Published: January 2023

Es wird eine Übersicht über die in Deutschland vorkommenden Bolboschoenus-Arten gegeben, die Bestimmungsschlüssel und Verbreitungsübersichten mit Listen geprüfter Belege enthält. Herbarrevisionen und Exkursionen sind Grundlagen der Arbeit. In Deutschland sind vier Bolboschoenus-Arten indigen: B. maritimus s. str. ist eine halophile Art der Küsten und Binnensalzstellen; B. laticarpus ist weit verbreitet in Süßwasserhabitaten, besonders in Flussauen; B. planiculmis ist eine seltene Art von Sekundärhabitaten, insbesondere Nassstellen in Feldern, von der aktuelle Funde nur aus Bayern und Sachsen-Anhalt bekannt sind; B. yagara ist ebenfalls eine seltene Art, deren Vorkommen in Fischteichen der sächsischen Lausitz, in Thüringen, Bayern und Baden-Württemberg liegen. Häufigkeiten, mögliche Ausbreitungstendenzen und Schutzbedürftigkeit werden diskutiert.

Prozesse innerhalb hybridisierender Pilosella-Populationen: P. aurantiaca und P. officinarum in Hagen (Nordrhein-Westfalen)
Authors: Krahulcová Anna , Raabe Uwe , Krahulec František
Published: January 2023

Pilosella aurantiaca – tetraploid, fakultativ apomiktisch und eingebürgert – und P. officinarum – tetraploid, sexuell und einheimisch – bilden bei Hagen, Nordrhein-Westfalen, einen Hybridschwarm aus tetra- und hexaploiden Pflanzen. Der Hybridschwarm wurde 1990 auf einer inzwischen brach gefallenen Wiese gefunden. Seit 20 Jahren kommt hier fast unverändert ein breites Spektrum von Hybriden vor: P. aurantiaca angenäherte Morphotypen (entsprechen P. rubra), intermediäre Morphotypen (P. stoloniflora) und verschiedene P. officinarum angenäherte Morphotypen. Diese Population wurde hinsichtlich Ploidiegrad, Genomgröße, Fortpflanzungssystem, Chloroplasten-Haplotypen und Isoenzym-Phänotypen untersucht. Der zu P. rubra korrespondierende Morphotyp ist hexaploid mit variabler Fortpflanzung. Er produziert neben apomiktischen einen erheblichen Anteil sexueller und polyha­ploider Nachkommen. Die Struktur des Genotyps und der DNA-Gehalt macht eine wiederholte Entstehung aus unreduzierten Eizellen von P. aurantiaca und reduziertem Pollen von P. officinarum (2n + n-Hybridisierung) wahrscheinlich. Die damit koexistierenden Hybriden (P. stoloniflora) sind tetraploid und sexuell. Bei P. officinarum wurden zwei Chloroplasten-Ha­plotypen gefunden, wovon einer auch bei P. aurantiaca vorkommt. Das Vorkommen eines Chloroplasten-Haplotypen bei P. officinarum, der typisch für P. aurantiaca ist, macht Rückkreuzungen wahrscheinlich. Die unterschiedlichen Genomgrößen der wahrscheinlichen Elternarten spiegeln sich in den Genomgrößen der homoploiden (tetraploiden) Hybriden wider. Eine mehrfache Rückkreuzung mit P. officinarum, wie sie durch die Morphologie wahrscheinlich gemacht wird, wird durch Genomgröße und Chloroplasten-Haplotypen gestützt.

This study aims to discuss the universal and important theme of how innovation supports the growth of global firms, relying on two issues: technology adoption and sustainability in the global marketplace. In other words, the main goal of this research is to show how global innovation management can respond to difficult market conditions and maintain sustainability of businesses through problem solving. The electric vehicle sector was chosen as the object of the study as it faced unprecedented challenges brought about by COVID-19. The electric vehicle sector has emerged as a new model in the automotive sector with accumulations of innovative technologies and is destined to continue to evolve, from the perspective of achieving the Sustainable Development Goals (SDGs) backed up by policy interventions. The methodological tools of the conducted research were the methods of office research, analysis of primary and secondary data, bibliometric analysis of literature. The article presents the results of an empirical study based on primary data collection and analysis, the generalization of scientific work on the impact of innovations on ensuring sustainable business development. Based on a comparative analysis of the main models of conducting innovative research, such as the diffusion model, business model innovation, and Lewin’s change management model, the most successful innovative solutions and the best practices of their implementation at specific companies are determined. The contribution of this study is to build on previous findings and academic discussions in the innovation field, analyse case studies of successful realization of sustainable business through innovative actions in response to unprecedented difficulties caused by the recent COVID-19 pandemic. The greatest contribution is to discuss the paths that innovation has successfully taken, with examples of specific companies, and to present a practical discussion agenda that will provide suggestions through stimulating further discussion in future research.
