Effects of Irrigation Water Salinity Levels on Pepper Plant (Capsicum Annuum) Yield and Quality Properties and Soil Characteristics
Authors: Maow Bashir A. , TEMİZEL Kadir Ersin
Published: January 2023

Plant tissues are 90% water. More efficient agricultural production techniques are needed to meet worldwide demand for water and food safety. In dry and semiarid locations, salty water is used for crop irrigation due to water constraint. Salinity, a major abiotic factor limiting agricultural productivity globally, affects osmotic adjustment and solute intake, causing many negative changes in morphological and physiological properties like photosynthetic rate and plasma membrane permeability of many economic plants. In this study, three different levels of EC were used and their effect on growth, yield, plant water consumption, chlorophyll content, soil and leaf ions, and soil ECe was determined. The resulting results are summarized as follows. The study found the increase in EC levels decreased the yield, biomass of the plants, leaf and root weights, leaves number, chlorophyll content of the leaves, and plant water consumption. EC treatments also increased the ion accumulation of leaves and soils.
Physiotherapy training and education prior to elective caesarean section and its impact on post-natal quality of life: A secondary analysis of a randomized controlled trial
Authors: Weerasinghe Kalani , Rishard Mohamed , Brabaharan Subhani , Walpita Yasasvi
Published: January 2023

Background
Caesarean section (CS) is associated with numerous complications that lead to the delayed return to functional activities that have a negative influence on the post-natal quality of life (QOL). It is evident that providing regular evidence-based physiotherapy training and education prior to elective CS helps to enhance the post-natal QOL by improving physical, mental, social, and general well-being. The purpose of this study was to examine the effectiveness of physiotherapy training and education prior to elective CS on post-natal QOL.
Methods
This single-blind parallel randomized controlled study was carried out at De Soysa Hospital for Women (DSHW), Colombo. The study enrolled 54 women who were scheduled to undergo elective CS. The intervention group (n = 27) of women received physiotherapy training and education, while the control group (n = 27) received standard nursing care. In addition to the primary outcome measures, post-natal QOL was measured. The results were examined using descriptive statistics and the independent samples t-test in IBM SPSS 20.
Results
The intervention group showed a higher post-natal QOL for the domains of physical function, role limitation due to physical health, energy/fatigue, and pain than the control group (p < 0.05).
Conclusion
Physiotherapy training and education prior to elective CS play a pivotal role in improving the physical health-related domains of QOL following CS.

Study adaptive backstepping control for My quadrotor
Authors: Duc Viet Nguyen , Ngoc Giang Le , Haiquan Zhao , Thi Ngoat Tran
Published: January 2023

Flight control for a quadrotor is a complicated task because of the complexity of the flight trajectory program and the uncertain changes in aerodynamic parameters, which make the system more complicated and nonlinear. Flight path angle tracking control consists of varied channels, such as a pitch controller, a roll controller, and a yaw controller. They are usually designed using traditional linear control methods, but this is not always satisfying, hence the more effective approach to controller design is backstepping. The backstepping control laws not only give the controllers certain gain margins but also deal with model errors in the description of aerodynamics. This paper presents a backstepping nonlinear controller design method for control systems involving quadrotors. Simulation results show that the control strategy proposed in this paper is effective and has strong robustness in the presence of disturbances and parameter uncertainty.
The impact of Federal Open Market Committee post-meeting statements on financial markets – a text-mining approach
Authors: Wójcik Piotr , Osowska Ewelina
Published: January 2023

This article examines the impact of Federal Open Market Committee (FOMC) statements on stock and foreign exchange markets with the use of text-mining and predictive models. Unlike in most previous studies, both linear and non-linear methods were applied. We estimate models using both the scheduled time of statement releases and the time the public first learns about the result of meetings. In addition, we also take into account additional explanatory variables that control for the current corporate managers’ and retail customers’ assessment of the economic situation. The proposed methodology is based on calculating the FOMC statements’ tone (called sentiment) and incorporate it as a potential predictor in the modeling process. For the purpose of sentiment calculation, we utilized the FinBERT pre-trained NLP model. Fourteen event windows around the event are considered. We proved that the information content of FOMC statements is an important predictor of the financial markets’ reaction directly after the event. In the case of models explaining the reaction of financial markets in the first minute after the scheduled announcement of the FOMC statement, the sentiment score was the second most important feature, after the market surprise component. We also showed that applying non-linear models resulted in better prediction of market reaction due to identified non-linearities in the relationship between the two most important predictors (surprise component and sentiment score) and returns just after the event. Last but not least, the predictive accuracy during the COVID pandemic was indeed lower than in the previous year.
C3AR1 promotes ovarian cancer progression and induces suppressive immunocyte infiltration: evidence from comprehensive bioinformatics analysis and experiments
Authors: Huang Jinfa , Zhou Lei , Deng Kaixian
Published: January 2023

Background
C3AR1 was reported in driving tumor immunity in multiple cancers. However, its roles in ovarian cancer remain unclear. This study aims to determine role of C3AR1 in prognosis and regulating tumor infiltrating immune cells of ovarian cancer (OC).
Material and Methods
The expression, prognosis and clinical data related to C3AR1 were collected from public databases such as The Cancer Genome Atlas (TCGA), Human Protein Atlas (HPA) and Clinical Proteomics Tumor Analysis Alliance (CPTAC), and further analyze their relationship with immune infiltration. Immunohistochemistry verified the expression of C3AR1 in ovarian cancer and control tissues. C3AR1 was forced expressed in SKOV3 cells by plasmid transfection, and verified by qRT-PCR and Western blot. Cell proliferation were evaluated by EdU assay.
Results
Bioinformatics analysis (TCGA, CPTAC) and immunohistochemical staining of clinical samples confirmed higher C3AR1 expression in ovarian cancer than that in normal tissues. High C3AR1 expression predicted adverse clinical outcome. KEGG and GO analysis showed that the biological processes of C3AR1 in ovarian cancer are mainly involved in T cell activation, cytokine and chemokine activation. C3AR1 expression was positively correlated with chemokines and their receptors in the tumor microenvironment, such as CCR1(R = 0.83), IL10RA (R = 0.92), and INFG (R = 74). In addition, increased C3AR1 expression predicted more infiltration of tumor-associated macrophages, dendritic cell and CD8 + T cell. Some important m6A regulators, such as IGF2BP2, ALKBH5, IGFBP3 and METL14, are significantly positively or negatively correlated with C3AR1. Finally, overexpression of C3AR1 significantly increased proliferation of SKOV3 cells.
Conclusion
In summary, our study suggest that C3AR1 is associated with the prognosis and immune cell infiltration of ovarian cancer, and is a promising immunotherapeutic target.

Authors: Li Shuang , Zhang Xiaojun , Zhang Xiaohong , Xu Yongju , Hou Rui , Zhu Xunlu
Published: January 2023

The plant-specific TCP transcription factors (TFs) play important roles in multiple processes of plant development and environmental stress response. However, the characteristics of TCP TFs in peanut are still unclear. In this study, we characterized the peanut TCPs including the numbers, classification, structures, and expression patterns based on the information from the available database. We identified 28, 9, and 8 TCPs in A. hypogaea cv. Tifrunner (AhTCP1-28), A. duranensis (AdTCP1-9), and A. ipaensis (AiTCP1-8), respectively. These genes can be divided into three groups based on the phylogenetic tree: PCF, CIN, and CYC/TB1. A total of 10 paralogous gene pairs in A. hypogaea cv. Tifrunner, five orthologous gene pairs between A. duranensis and A. hypogaea cv. Tifrunner and five orthologous gene pairs between A. ipaensis and A. hypogaea cv. Tifrunner, were identified respectively. Most duplicated gene pairs underwent purifying selection except AdTCP2-AhTCP15 and AiTCP8-AhTCP28 were subjected to positive selection. Hormone-related and abiotic stress response elements were abundant in several TCP gene promoters in A. hypogaea cv. Tifrunner. AhTCP12 and AhTCP25 contained four EREs (ethylene-response elements), and AhTCP15 included four TCA elements. Most of TCPs were expressed lowly in 22 tissues, however, several genes such as AhTCP25 and a homologous gene pair, AhTCP13 and AhTCP28, were expressed highly in peg tip and perianth, respectively. AhTCP duplicated gene pairs did not show significant functional differentiation. This study provided insight into the evolution and expression of AhTCPs and might assist peanut molecular breeding.

Authors: Mutluer Ferit Onur , Bowen Daniel J. , Grootel Roderick W. J. , Kardys Isabella , Roos-Hesselink Jolien W. , Bosch Annemien E.
Published: January 2023

PURPOSE:
To demonstrate prognostic utility of left atrial strain(LAS) in adult patients with repaired Tetralogy of Fallot(rTOF).
METHODS:
Adults patients with rTOF were prospectively enrolled in this study between years 2011-2015. Left atrium(LA) phasic functions were assessed using 2D speckle tracking echocardiography(2D-STE). Association of LA strain(LAS) with primary(any cardiovascular event) and secondary(death, heart failure or arrhythmia) composite endpoints was assessed using Cox regression analysis.
RESULTS:
Hundred-and-twelve rTOF patients, in whom LAS was feasible and were in sinus rhythm, were included in the final analysis (age 33±10 years, 68[61%] male). Median duration of follow-up was 8.6[4.2-9.7] years in the study group. Primary composite endpoint was reached in 48 patients (mean event-free survival time: 7.2[6.6-7.9] years), and secondary composite endpoint was reached in 22 patients (mean event-free survival time: 8.7[8.1-9.2] years). LAS-r was defined as tertile groups(1st tertile<33 %,2nd tertile=33-44%,3rd tertile>44%). Decreasing tertiles of LAS-r was associated with primary and secondary composite endpoints in Kaplan-Meier analysis(p=0.02 and 0.002, respectively). In univariable Cox-regression, both decreasing LAS-r and LAS-r tertiles were associated with primary and secondary composite endpoints. Adjusted by initial repair age and NT-proBNP quartiles, increased LAS-r was associated with significantly decreased occurrence of experiencing any events(HR=0.97,CI:0.93-0.99,p=0.037]). Decreasing LAS-r was still associated with primary endpoint when adjusted by left atrium volume index(LAVImax)(HR=0.96,CI:0.03-0.99,p=0.01),left ventricle global longitudinal strain(LV-GLS)(0.95,95%CI:0.92-0.98,p=0.002) or right ventricle free wall longitudinal strain (RV-FWLS)(0.96,95%CI:0.93-0.99,p=0.04).
CONCLUSION:
Assessment of LA mechanics with the use of STE has incremental utility in determination of mortality and morbidity in rTOF, and may be implemented in clinical practice.
Research on the Effect of Mindfulness Practice on Susceptibility to Evaluative Conditioning
Authors: Ye Jinhui , Zhong Liangjing , Li Bonan , Hu Shengyuan , Wang Xiaoyan
Published: January 2023

Background
Susceptibility to evaluative conditioning(EC) is associated with many social cognitive and psychological biases that are key to psychological problems. For example, depression and anxiety are closely related to susceptibility to negative stimuli, and susceptibility to positive stimuli is associated with healthy psychology and well-being. Therefore, susceptibility to evaluative conditioning is closely related to mental health and cannot be ignored. As a factor that can affect the susceptibility to evaluative conditioning, mindfulness has only recently received attention. This study aims to to provide more targeted services for health clubs wishing to support well-being and mental health.
Methods
To explore the feasibility and effect of mindfulness interventions on susceptibility to evaluative conditioning, 72 subjects were included in a fitness club in Hefei. Thirty-six of the subjects participated in mindfulness training with the Mindful Attention Awareness Scale (MAAS), Positive and Negative Emotion Scale (PANES), and using the evaluative conditioning paradigm(picture-picture paradigm) for examination.
Results
The results of the correlation and comparison of differences showed susceptibility to evaluative conditions, and the difference in the experimental group was significant before and after the intervention (P ༜0.05).
Conclusions
Compared to a control group, 12 hours of yoga and mindfulness training improved mindfulness, as measured on the Mindful Attention Awareness Scale, a decrease in negative susceptibility leads to a relative increase in positive susceptibility, therefore, people can feel more positive and have better mental health.

Authors: Terpstra L. C. , Altenburg J. , Doodeman H. J. , Piñeros Y. S. Sabogal , Lutter R. , Heijerman H. G. M. , Boersma W. G.
Published: January 2023

Background
Long term macrolide treatment has been found beneficial in bronchiectasis (BE) -pathogical bronchial dilatation- possibly due to a combined anti-bacterial and immunomodulatory effect. The exact mechanism of inflammatory response is unknown. Here, we investigated the effect of maintenance macrolide treatment on the inflammatory response in BE. In addition, we assessed the inflammatory profile in BE in relation to disease severity.
Methods
During the BAT randomized controlled trial (investigating the effect of 1 year of azithromycin (AZM) in 83 BE patients), data on BE severity, lung function and sputum microbiology was collected. For the current study, a wide range of inflammatory markers were analysed in 3- monthly sputum samples in all participants.
Results
At baseline, marked neutrophilic but also eosinophilic inflammation was present in both groups, which remained stable throughout the study and was not affected by AZM treatment. Significant upregulation of pro-inflammatory markers correlated with FEV1 < 50% (TNFα, ECP, IL-21, IL-1, p = 0.01–0.05), H. influenzae (HI) colonization (MPO, ECP, MIP-1, TNFα, IL-21, Il-8, IL-1, IL-1α, p < 0.001–0.04) and number of exacerbations (MPO, ECP, VEGF, MMP-9, p = 0.003–0.01). Surprisingly, colonization with P. aeruginosa (PA) was found to correlate with an attenuated inflammatory response compared to non-PA colonized. In placebo-treated patients, presence of an infectious exacerbation was reflected by a significant excessive increase in inflammation as compared to a non-significant upregulation in the AZM-treated patients.
Conclusion
One year of AZM treatment did not result in attenuation of the inflammatory response in BE. Increasing disease severity and the presence of an exacerbation were reflected by upregulation of pro-inflammatory markers.
The 100 cited articles in menstrual health among adolescent girls: A Citation analysis
Authors: Alekhya G. , Sahu Dinesh Prasad , Behera Priyamadhaba
Published: January 2023

Background: Menstrual health is a public health concern where it is still considered taboo, and adolescent girls lack knowledge about menstrual health, access to sanitation facilities, and the affordability of sanitary materials. Every year numerous articles are published; however, only a few of them would be influential in the evolution of a particular field. The number of citations received by an article serves as a quality factor for the impact of the article in a particular field. Citation analysis analyses the relationship between citations received by articles. From the literature search, no citation analysis was conducted on menstrual health. Hence the objective of the study was to identify the articles which received a hundred or more citations and also to identify the leading countries, journals, study designs, and departments conducting research on menstrual health.
Methods: Citation analysis was done with search terms pertaining to adolescent and menstrual health using google scholar as a database in Publish or Perish software. The articles retrieved were exported to Microsoft Excel. Articles that received a hundred and more citations were screened for the type of article, department, and country where the study was conducted, and articles that were books, patents, and non-journal publications were excluded. A descriptive analysis of the hundred and more cited articles was done in Microsoft Excel.
Results:A total of 980 articles pertaining to menstrual health among adolescent girls were retrieved. There were a hundred articles with hundred and more citations pertaining to the menstrual health of adolescent girls. There were five citation classics among the hundred articles with hundred and more citations. Cross-sectional study design, Obstetrics and Gynaecology department, India and USA countries, and PLOS ONE journal, had the most citations in research on menstrual health among adolescent girls. The top ten articles were on menorrhagia, menstrual hygiene practices, Water, Sanitation and hygiene (WASH), stigma on menstruation, and education on menstrual health.
Conclusion: The present citation analysis analyses the top countries, journals, and departments conducting research on menstrual health, and there is an immediate need to strengthen research in lower-income countries and conduct more interventional studies.
Differentiating heavy cannabis users through latent class analysis
Authors: Alvarez-Roldan Arturo , García-Muñoz Teresa , Gamella Juan F. , Parra Iván , Duaso Maria J.
Published: January 2023

Background: Daily or near-daily cannabis users vary considerably in their daily dosage and use frequency, impacting both experienced effects and adverse consequences. This study identified heavy cannabis user groups according to consumption patterns and factors associated with class membership.
Methods: We conducted a cross-sectional survey of 400 Spanish residents (62.2% male; average age=29.6 years) who had used cannabis ≥3 days/week throughout the past year. Participants were recruited through chain referral and cannabis social clubs. We applied latent class analysis (LCA) to cluster participants according to use intensity. Associations between class membership and socio-demographics, use patterns, motives, supply sources, adverse outcomes, and use of other substances were measured using ANOVA and chi-squared tests. Multinomial regression identified the factors associated with latent class membership.
Results: Three latent classes (moderately heavy: 23%, heavy: 67.5%, very heavy: 9.5%) had average weekly cannabis intakes of 2.3, 5.6, and 18.3 grams, respectively. Age, education, years of use, buying cannabis in a club, Cannabis Abuse Screening Test (CAST) scores, and cocaine use were associated with cannabis use intensity. Very heavy users were older ( X2 =20.44, p<0.01), less educated X2=28.92, p<0.001), and had used cannabis for longer (F=6.80, p=0.001). The prevalence of past-month cocaine use ( X2 =13.90, p<0.05) and CAST scores (F=25.73, p<0.001) increased across the classes. Cannabis was usually obtained from a club by very heavy users ( X2 =24.40, p<0.001).
Conclusions: Heavy cannabis users are heterogenous and present several groups according to frequency and quantity of cannabis consumption. Use intensity is associated with increased cannabis use disorders and dependence.
Implementation of 2D Ray SBR Modeling for different MIMO Antenna Array placement in Outdoor communication using Wireless InSite software
Authors: Abdulwahid Maan Muataz , KURNAZ Sefer
Published: January 2023

This study proposes a Multiple Input Multiple Output (MIMO) antenna array with three orientations for the transmitter device, as well as a 2-Ray Model for dealing with communications in an outdoor scenario. This orientation would be referred to as the (Horizontal, Vertical and Planar). Line of Sight (LoS) rays and ground-based reflected rays between the Tx and Rx have been incorporated in the proposed 2-Ray model. The research was carried out by using the most relevant software for route propagation-based ray tracing (Wireless InSite software) with the latest version in 2023. Different factors and Tx heights were examined when examining the findings for our study. The affects seen in the three examples were caused by the effects of varied antenna polarization, directivity, and diversity methods. Results obtained can confirm the reliable and optimum MIMO point placement as an array that can achieve the best overall transmission with less losses.
Investigation of ANN structure on predicting the fracture behavior of additively manufactured Ti-6Al-4V alloys
Authors: Sarparast Mohsen , Shafaie Majid , Babakan Ahmad Memaran , Davoodi Mohammad , Zhang Hongyan
Published: January 2023

Selective laser melting (SLM) is a prevalent additive manufacturing (AM) technique for the fabrication of metallic components. A modified GTN (Gurson-Tvergaard-Needleman) model was developed, based on the understanding of the SLM process and SLM-manufactured parts, in order to characterize void growth and void shear mechanism to predict the ductile fracture behavior of SLM-fabricated Ti6Al4V alloys under uniaxial stress states. The effect of the number of hidden layers and neurons, as a basic parameter of an artificial neural network (ANN), on predicting parameter relation accuracy was investigated. In this study resulted due to the complex relation among GTN fracture parameters and fracture displacement, defining more hidden layers in ANN improves the accuracy of predicting the damage and fracture behavior of SLM-fabricated Ti6Al4V alloys under uniaxial stress states; however, forecasting maximum force is achieved accurately by fewer hidden layers in comparison with fracture displacement needing to higher layers to predict precisely. Furthermore, the system R 2 -value reaches higher accuracy more than 0.99 for both maximum force and fracture displacement based on selected hidden layers and neurons.

Published: January 2023

Der Anbau des in Zentralasien beheimateten diploiden, sexuellen Taraxacum koksaghyz als Kautschuklieferant in Deutschland erfährt eine Renaissance. Das invasive Potenzial dieser Art in Bezug auf die autochthone Vegetation erweist sich als extrem gering. Feldversuche zeigten den Zusammenbruch einer kompletten Population von T. koksaghyz innerhalb eines Jahres bei Auflassung und natürlicher Sukzession. Hybridisierungen zwischen T. koksaghyz mit autochthonen Taraxacum-Arten wurden nicht beobachtet. Das frühe Stadium der Domestikation von T. koksaghyz zeichnet sich durch große morphologische Variabilität der Art aus, die dokumentiert wird.
Anmerkungen zur Nomenklatur von Hieracium kalksburgense Wiesb. und Wiedereinsetzung des Namens Hieracium canum Peter
Authors: Gottschlich Günter
Published: January 2023

Das Typus-Material von Hieracium kalksburgense ist heterogen und entspricht nicht dem taxonomischen Umfang, der dieser Zwischenart bisher zugeschrieben wurde. Der Name H. kalksburgense wird deshalb mit einem Beleg lektotypisiert, der entsprechend den Intentionen des Erstbeschreibers zu H. acutifolium gehört, und damit synonymisiert. Als Konsequenz wird für die Zwischenart "cymosum < pilosella" der Name H. canum Peter wieder aufgenommen und lektotypisiert. Da es im alternativen Gattungskonzept unter Pilosella für diese Art keinen gültigen Namen gibt, wird eine Umkombination zu Pilosella vorgenommen.

Published: January 2023

Die Sand-Quecke, Elymus arenosus, ist eine in ihrer Umgrenzung, taxonomischen Bewertung und geographischen Verbreitung umstrittene Art. Während einige Autoren sie als Endemiten des Mainzer Sandes betrachten, wird sie von anderen Autoren, häufig als Unterart, als auch an den Küsten Nordwesteuropas weitverbreitet aufgefasst. Unter Verwendung von plastidären trnL-trnF und nukleär-ribosomalen ITS-Sequenzen wird hier versucht, die Identität, Verbreitung und mögliche Verwandtschaft von E. arenosus zu klären. Individuen vom Mainzer Sand haben einen nur ihnen eigenen trnL-trnF-Haplotypen, der auch in als E. arenosus identifiziertem Material aus den Niederlanden (Millingerwaard) gefunden wurde, sowie einige nur ihnen eigene ITS-Ribotypen. In Verbindung mit der ihr eigenen Morphologie und älteren Berichten der Art vom Oberrhein führt uns das zu dem Schluss, dass E. arenosus als Art bewertet werden sollte und ehemals entlang des Rheins weiter verbreitet war. E. arenosus hat eine Chromosomenzahl von 2n = 28. Molekulare und morphologische Ähnlichkeiten lassen es möglich erscheinen, dass E. campestris der engste Verwandte von E. arenosus ist.

Erstnachweis von Dryopteris affinis s. str. (Dryopteridaceae, Pteridophyta) für Nordrhein-Westfalen
Authors: Bennert Herbert Wilfried , Neikes Norbert , Gausmann Peter , Jäger Wolfgang , Lubienski Marcus , Viane Ronald
Published: January 2023

Neuerdings werden fünf Sippen des Dryopteris-affinis-Komplexes in Mitteleuropa als eigenständige Arten bewertet, wovon vier auch in Nordrhein-Westfalen (NRW) vorkommen. Dazu gehören die triploide D. bor­reri, die offenbar die mit Abstand häufigste Art repräsentiert, und zwei weitere triploide Arten, D. pseudodisjuncta und D. lacunosa. Letztere wurde erst vor kurzem neu beschrieben und ist in NRW bislang nur von einem Fundpunkt bekannt. Mit Hilfe der Flow-Cytometrie gelang es nun, eine auf Grund der kleinen Sporen verdächtig erscheinende Pflanze aus dem Schwalm-Nette-Gebiet als diploide D. affinis s. str. zu identifizieren. Die anfängliche Vermutung, diese Art sei auf Tiefland-Vorkommen im deutlich atlantisch getönten äußersten Nordwesten von NRW beschränkt, haben sich als unzutreffend erwiesen; die Art konnte nachfolgend auch mehrfach im Süderbergland gefunden werden. Ebenfalls mit Hilfe der Flow-Cytometrie wurden eine Reihe von Vorkommen von D. borreri bestätigt sowie tetra- und pentaploide Hybriden (D. ×complexa und D. ×critica) nachgewiesen, die durch Bastardbildung mit D. filix-mas entstehen. Während Vorkommen der pentaploiden D. ×critica bereits seit längerer Zeit aus NRW bekannt sind, handelt es sich bei denjenigen von D. ×complexa ebenfalls um Erstnachweise. Das nordrhein-westfälische Areal dieser Sippen wird in drei Fundortkarten dargestellt (für den D.-affinis-Komplex insgesamt sowie für cytologisch bzw. flow-cytometrisch bestätigte Vorkommen der beiden Arten D. affinis s. str. und D. borreri sowie der beiden Hybriden D. ×complexa und D. ×critica). Aus einer mit der räumlichen Verteilung der Jahresniederschläge kombinierten Verbreitungskarte wird die enge Bindung an niederschlagreichere Lagen (zumeist mehr als 800 mm) deutlich. Dies und weitere standortökologische Besonderheiten weisen darauf hin, dass die Sippen des D.-affinis-Komplexes in größerem Maße von der Wasserversorgung abhängig sind als D. filix-mas. Zwar repräsentieren die D.-affinis-Sippen offenbar typische Waldfarne und zeigen eine Präferenz für bodensaure Buchenwald-Gesellschaften, vor allem D. affinis s. str. kommt aber auffallend häufig an anthropogen überformten Sekundärstandorten vor, so an Weg- und Grabenböschungen, in Abgrabungen sowie an einem künstlichen Steilhang und in einem Steinbruch.

Festuca tomanii sp. nov., ein Dünen-Schwingel des nördlichen Oberrhein-, des mittleren Main- und des böhmischen Elbetal
Authors: Korneck Dieter , Gregor Thomas
Published: January 2023

Auf basenreichen Sanden des nördlichen Oberrhein-, mittleren Main- und böhmischen Elbetales wachsende, blaugrün bereifte tetraploide Schwingel, die bisher meist als Festuca duvalii angesprochen wurden, werden als F. tomanii neu beschrieben. von F. duvalii unterscheidet sich F. tomanii durch (1) pergamentartige Scheiden der Grundblätter, von denen die Spreiten frühzeitig abfallen (F. duvalii: Scheiden der Grundblätter nicht pergamentartig, Spreiten lange erhalten bleibend), (2) dickere Blätter (0,8–1,1 mm vs. 0,6–0,9 mm) mit mehr Leitbündeln (9–11 vs. 7) sowie (3) durch einen ± geschlossenen Sklerenchymring (F. duvalii: Sklerenchym überwiegend in drei Bündeln). Die Bestände von F. tomanii sind stark rückläufig; die meisten Populationen finden sich an Reliktstandorten. F. tomanii ist ein typischer Bestandteil des Jurineo cyanoidis-Koelerietum glaucae (Koelerion glaucae).
Stellaria-media-Gruppe in Mitteleuropa – Chromosomenzählungen und Anmerkungen zu den Differentialmerkmalen
Authors: Hügin Gerold , Dersch Gunther , Gregor Thomas
Published: January 2023

Aus der Stellaria-media-Gruppe wurden Chromosomenzahlen aus Mitteleuropa (Deutschland, Frankreich, Schweiz) ermittelt: S. apetala (2n = 22), S. media (2n = 40, 2n = 80), S. neglecta (2n = 22). Ergänzend erfolgte eine flowzytometrische Untersuchung. Wegen großer genetischer und standörtlicher Variabilität der S. media kann vor allem die Unterscheidung von S. neglecta schwierig sein. Bei der Bestimmung ist immer auf den gesamten Merkmalskomplex zu achten, insbesondere auf Samengröße und Staubblattanzahl. Näher eingegangen wird auf das meist überbewertete Merkmal "Samenhöcker" und das bisher nur wenig beachtete Merkmal "Samenmasse" (Hundertkornmasse).
Assessing the Impact of Friendly Family Practice in Reducing Employee Turnover in Malaysian Private Higher Educational Institutions
Authors: Aik Nelson Teh Song
Published: January 2023

The main purpose of the research is to identify the effectiveness of implementing family-friendly practices in reducing turnover amongst academicians in private higher education institutions, with the mediator effect on job satisfaction. Systematization of the literary sources and approaches for solving the employee turnover problem indicates that friendly family practice includes three dimensions: flexible working arrangements, parental leave and childcare benefits. During the investigation, these three variables will be evaluated for their relationship with turnover and whether there is any significant or effective association among the variables. The research proves that for many private higher educational institutions, the expansion required a considerable effort to have knowledgeable academicians and skillful employees. Thus, they could deliver their professions and skills to achieve education goals. However, retaining the employee is always the main issue faced by many institutions and many scholars have formulated strategies to minimise turnover. Most of them claim that if the strategies are properly implemented, organization turnover will be reduced, thus developing a highly committed and motivated employee. Hence, this study has developed five (5) research questions and ten (10) hypotheses. To test the hypotheses, a sample of 316 employees from different educational institutions was selected through a cluster sampling method to respond to the questionnaire. The methodological tools of the conducted research were methods of multivariate statistical analysis, and Structural Equation Modeling (SEM). The outcome of the research provided researchers with an understanding that flexible work arrangements, provision of parental leave and childcare benefits have a significant negative relationship with employee turnover intention. Besides that, the outcome also confirmed that there is a mediation effect of job satisfaction towards family-friendly practices and turnover intention.

Sportfilmek nyomában, avagy fogyasztási preferenciák
Authors: Gősi Zsuzsanna , Erdélyi Éva , Bukta Zsuzsanna , Magyar Márton
Published: January 2023

Sportról szóló filmeket kivétel nélkül szinte mindenki ismer. A legfőbb erénye ezeknek a filmeknek, hogy követendő példát mutatnak. Számos film igaz történet alapján készül, egy-egy élettörténetet mesél el. A sport szépségei mellet részben bemutatják azokat a nehézségeket is, melyek egy sportkarriert körülvesznek. A másik pozitív hatása az ilyen típusú filmeknek, hogy egy passzív tevékenység után mozgásra ösztönöznek. Egy hiánypótló, egyedi kutatással megpróbáltuk feltérképezni a fogyasztási szerkezetet és az esetleges befolyásoló tényezőkkel való kapcsolataikat a sportfilmek példáján keresztül. Megállapítható, hogy a közismertnek gondolt sportfilmek egy része valóban közismert (mint például a Tűzszekerek), illetve konkrétan a futás kapcsán a Forrest Gump. A sportról szóló dokumentumfilmek kedveltsége és a filmnéző sportolási szokásai között összefüggés fedezhető fel, ám a sportolási gyakoriság nem befolyásolja a sportközvetítések nézését. A vizsgálat minta alapján a sportfilmek nem ösztönzik a nézőket egyértelműen a sportolásra.
The Effect of Entrepreneurial Factors on the Realization of Sustainable Development Goals (SDG) and Sustainability in Indonesia’s SMEs
Authors: Putri Anindia Pratiwi , Dhewanto Wawan
Published: January 2023

The International Monetary Fund (IMF) predicts Indonesia with lower economic growth than other countries in South Asia. This problem can be addressed by understanding the values ​​of Sustainable Development Goals (SDG) 8 about decent work and economic growth. However, previous research has not identified entrepreneurial factors that drive SDG 8 and how they affect sustainability. The research aimed to analyze the interrelationships of entrepreneurial factors in realizing SDG 8 and sustainability scientifically and systematically to fill the gap. The research applied a quantitative method. Small and Medium-Sized Enterprises (SMEs) in Bandung were selected as the research population using the purposive sampling method. Questionnaires were distributed to 153 SMEs as a data collection method. A seven-point Likert scale was used to measure respondents’ agreement for each item or statement. Then, the data were processed using PLS-SEM. The research finds that entrepreneurial intentions and behavior are entrepreneurial factors with a significant positive effect on SDG 8. In addition, SDG 8 has a significant positive effect on sustainability (social, economic, and environmental). Last, the research also contributes to increasing the entrepreneurs’ awareness in understanding the importance of motivation, entrepreneurial intentions, and SDG 8 to realize sustainable SMEs.

Published: January 2023

The retail industry in Indonesia is still in the transition phase from multichannel to omnichannel. Hence, the behavior of shoppers is divided into two broad categories, namely multichannel and omnichannel shoppers. The research aimed to know the socio-demographic characteristics of multichannel and omnichannel shoppers in Indonesia. It also tested the difference between both in showing cross-channel behavior and loyalty to the retailers. The data were obtained by questionnaires from 341 respondents with purposive sampling. The descriptive method with cross-tabulation analysis was applied to capture the socio-demographic characteristics of multichannel and omnichannel shoppers. Meanwhile, the comparative method with an independent sample t-test tested the difference between both types of shoppers in showing cross-channel behavior and loyalty to the retailers. The results show that millennial and female shoppers are the most potential segment at this time to be targeted in the context of omnichannel retailing. Both multichannel and omnichannel shoppers are dominated by those whose income is less than Rp4,5 million to Rp10 million with 3 to 5 persons in their household. Moreover, there are significant differences between multichannel and omnichannel shoppers in the context of cross-channel behavior and loyalty. Omnichannel shoppers show cross-channel behavior and loyalty more than multichannel shoppers.

Thromboembolic syndrome, the frequency of which is 8–15%, is the main danger for a patient with atrial fibrillation (AF). The left atrial appendage is the most common source of thromboembolia in atrial fibrillation. The frequency of detection of left atrial appendage thrombus in AF is 15.2% in the absence of anticoagulant therapy and 1–8% in patients using this group of drugs. The reason for the formation of thrombi in this localization during anticoagulant therapy today it is not reliably known. This article describes a clinical case of a 67-year-old patient with persistent AF and left atrial appendage thrombosis, who was hospitalized to determine further management strategies. A left atrial appendage thrombus lasted for a year despite continuous anticoagulant therapy with various oral anticoagulants at doses consistent with clinical guidelines due to the patient's absolute refusal to take warfarin, vitamin K antagonist. In addition, this article discusses the use of Thrombodynamics, a new global coagulation test, in patients with AF, which revealed a plasma hypercoagulable state with underlying persistent thrombosis in this patient on continuous oral anticoagulant treatment. The Thrombodynamics test is a promising procedure for assessing the coagulation system state and may be promising as a method for measuring the effectiveness of any oral anticoagulant. However, it is impossible to draw any definite conclusions on the basis of single observations; large clinical studies with the potential of long-term case follow-up of patients are needed.
