Two of a kind or distant relatives? A multimethod investigation of the overlap between personality traits and character strengths
Authors: Ruch Willibald , Vylobkova Valentina , Heintz Sonja
Published: June 2021

Allport’s distinction of personality devaluated (personality) and personality evaluated (character) raised the question if character is redundant with personality, which still remains open today. The present study hence compares the Five-Factor Model of personality and the VIA-classification of character strengths across two methods (self- and peer-reports) and across two levels of abstraction (domains/factors and scales/facets). A sample of 152 participants and 152 peer-raters completed the NEO-Personality Inventory Revised and the VIA Inventory of Strengths. Personality and character assessed with these inventories were found to strongly overlap, yet the different operationalizations were rarely redundant (except for three personality facets). Multitrait-multimethod analyses mostly supported the convergent and discriminant validity of personality and character. Interpersonal strengths (e.g., teamwork) and abstract character factors lacked discriminant validity to personality facets. The present investigation contributes to a better understanding of the interplay between personality and character and provides an impetus for future research on the “virtue gap” between devaluated and evaluated personality traits.
As Within, so Without; As Above, so Below: Common Mechanisms Can Support Between- and Within-Trial Learning Dynamics
Authors: Weichart Emily Ruth , Galdo Matthew , Sloutsky Vladimir , Turner Brandon
Published: June 2021

Two fundamental difficulties when learning is deciding 1) what information is relevant, and 2) when to use it. To overcome these difficulties, humans continuously make choices about which dimensions of information to selectively attend to, and monitor their relevance to the current goal. Although previous theories have specified how observers learn to attend to relevant dimensions over time, those theories have largely remained silent about how attention should be allocated on a within-trial basis, which dimensions of information should be sampled, and how the temporal ordering of information sampling influences learning. Here, we use the Adaptive Attention Representation Model (AARM) to demonstrate that a common set of mechanisms can be used to specify: 1) how the distribution of attention is updated between trials over the course of learning; and 2) how attention dynamically shifts among dimensions within-trial. We validate or proposed set of mechanisms by comparing AARM’s predictions to observed behavior across five case studies, which collectively encompass different theoretical aspects of selective attention. Importantly, we use both eye-tracking and choice response data to provide a stringent test of how attention and decision processes dynamically interact. Specifically, how does attention to selected stimulus dimensions gives rise to decision dynamics, and in turn, how do decision dynamics influence our continuous choices about which dimensions to attend to via gaze fixations?
A scoping review of experimental manipulations examining the impact of monetary format on gambling behaviour
Authors: Palmer Lucas , Cringle Natalie , Clark Luke
Published: June 2021

Gambling involves monetary bets and prizes, but the money can take a range of formats, including cash, chips, ticket-in ticket-out vouchers, and digital options including banking cards. As societies move towards cashless payment for many goods, the question arises of how emerging payment technologies might impact gambling related harms. We performed a scoping review following PRISMA guidelines to identify research testing the effects of monetary format in gambling. Our eligibility criteria focused on controlled experimental manipulations, to best establish the causal impact of monetary format. We sought to characterize different types of monetary manipulations that have been studied in a gambling context. We identified 15 eligible articles, comprising 18 individual experiments. These experiments were organized according to four distinct manipulations. The most common design (11 experiments), compared gambling under the presence or absence of money. Smaller numbers of experiments were identified manipulating monetary salience, testing Responsible Gambling tools, and testing the impact of promotional inducements. We identified no studies that compared gambling using cash against alternative payment forms. Our review highlights a paucity of research testing the possible impact of digital and cashless payment options on gambling related harms, using experimental designs that would permit causal conclusions to be drawn.
High national acceptance for COVID-19 contact tracing technologies in Taiwan
Authors: Garrett Paul Michael , Wang Yu Wen , White Joshua Paul , Kashima Yoshihisa , Dennis Simon , Cheng-Ta
Published: June 2021

Taiwan has been a world leader in controlling the spread of SARS-CoV-2 during the COVID-19 pandemic. Recently, the Taiwan Government launched its COVID-19 tracing App the `Taiwan Social Distancing App', however the effectiveness of this tracing App depends on its acceptance and uptake among the general population. We measured acceptance for three hypothetical tracing technologies (telecommunication network tracing, a government App, and the Apple and Google Bluetooth exposure notification system) in four nationally representative Taiwanese samples. Using Bayesian methods, we find high acceptance for all three tracking technologies, with acceptance increasing with the inclusion of additional privacy measures. Modelling revealed acceptance increased with the perceived technology benefits, trust in the providers' intent, data security and privacy measures, the level of ongoing control, and one's level of education. Acceptance decreased with data sensitivity perceptions, and perceived low policy compliance by others in the general public. We consider the policy implications of these results for Taiwan during the COVID-19 pandemic and into the future.
Addressing the Disparity in Refugee Mental Health Services: a Pilot Study of a Traumatic Stress Intervention Utilizing a Language‑Free mHealth Application
Authors: Mazzulla Emily , Fondacaro Karen M. , Weldon Holly C , Dibble Marguerite , Price Matthew
Published: June 2021

Objective: After resettlement, an overwhelming number of refugees struggle with Chronic Traumatic Stress (CTS), the persistence of traumatic events (e.g., re-experiencing past trauma; news of on-going war) coupled with daily post-migration stressors (e.g., poverty, lack of transportation). CTS significantly increases the burden of mental health challenges experienced by refugees. Evidence-based mental health treatments often rely on worksheets, mobile applications, websites, or telephone calls to facilitate the management of distress outside of treatment sessions. Language barriers prevent these strategies from being incorporated into mental health treatment for refugees, which results in a significant disparity in care. Treatments delivered via mobile devices can address this barrier through the use of intuitive images that eliminate the need for text or language-based instruction.Methods: A six-week pilot study assessing the effectiveness of group intervention utilizing a language free, culturally relevant mobile health (mHealth) application was conducted in a sample of Somali-Bantu and Nepali-Bhutanese adult refugee men and women (N=18). Paired-samples t-tests were conducted to compare pre- and post-intervention levels of psychosocial distress, anxiety, depression, and traumatic stress, on the Refugee Health Screener (RHS-15) and an investigator generated coping measure.Results: Results indicated significant reduction (p<.001) in symptoms related to traumatic stress, anxiety, depression and somatic complaints in addition to a significant increase (p<.001) in the use of coping skills.Conclusions: The use of a mobile mental health app, in combination with in-person therapy, was effective in reducing mental health symptomology and in increasing the use of coping skills in Somali-Bantu and Nepali-Bhutanese refugees.
Subjective Social Class and Life Satisfaction: The Role of Class Consistency and Identity Uncertainty
Authors: Tang Bek Wuay , Tan Jacinth Jia Xin
Published: June 2021

Drawing on a recent perspective that inconsistent class identities can negatively impact psychological outcomes, the current research explored if the relative benefit of higher subjective social class for life satisfaction would differ depending on whether it is consistent with one’s objective social class. In Study 1, across two independent samples from Singapore (N = 1045) and the US (N = 492), higher subjective social class predicted higher life satisfaction more strongly among those high in objective social class, but less strongly among those low in objective social class. In Study 2, these patterns were replicated in another large US sample (N = 1030), and appeared to be driven by lower status-based identity uncertainty (SBIU) linked to higher subjective social class perceptions among high objective social class participants. The role of class-identity perceptions in explaining social class disparities in subjective well-being is discussed.
Self-Objectification and Sexual Satisfaction: A Preregistered Test of the Replicability and Robustness of Calogero & Thompson (2009) in a Sample of U.S. Women
Authors: Clapp Abbie , Syed Moin
Published: June 2021

Objectification theory has provided a useful framework for the study of women’s sexual outcomes. However, little research has been conducted on the role of self-objectification in predicting sexual satisfaction. We conducted a replication of Calogero and Thompson (2009a), which reported a direct relationship between self-surveillance and sexual satisfaction, and expanded upon their work. We tested four path analysis models: Calogero and Thompson’s reported and hypothesized models, and two previously untested models, all containing our variables of interest (media internalization, self-surveillance, body shame, sexual self-esteem, and sexual satisfaction). Each model was tested with the full sample (N = 349) and a restricted sample (N = 127) that met Calogero and Thompson’s relationship status and sexual frequency inclusion criteria, and with and without BMI covaried. Both samples consisted of U.S. college women recruited in Fall 2019, with a mean age of M = 19.68 in the restricted sample. Results showed good fit for all tested models but failed to replicate the direct pathway between self-surveillance and sexual satisfaction. Instead, our models supported an indirect effect of self-surveillance on sexual satisfaction through body shame and sexual self-esteem. Findings support the role of sociocultural channels in influencing college women’s body image and sexual experiences.
Openness and Diversity in Journal Editorial Boards
Authors: Altman Micah , Cohen Philip N.
Published: June 2021

This study aims to measure diversity in scholarly journals’ editorial board structure and characterize patterns of editorial diversity across types of journals. To accomplish these aims, we integrate multiple sources of data at the journal and editor level to assemble a novel database describing the composition of editors and editorial boards for more than six thousand journals internationally, characterized by discipline, commercial publishing model, and research transparency. We then apply name-based gender imputation, geo-entity extraction analysis, and standardized dispersion measures to evaluate each group’s diversity. This analysis reveals that editorial leadership is more homogenous than editorial boards, and that diversity across both boards and leadership varies substantially (and robustly) across disciplines. Open-access journal’s boards exhibit less gender diversity and more international diversity than their closed-access counterparts. These results also suggest that open access, open science, and diversity, and equity, and inclusion are not strongly correlated and thus require separate measurements.
Demographic Diversity of the Aromantic/Asexual Spectrum in Japan: Findings from the 2020 Aro/Ace Survey
Authors: Miyake Daijiro , Hiramori Daiki
Published: June 2021

In Western countries, studies using representative surveys and community surveys have begun to reveal the size and the diversity of the asexual population. On the other hand, in Japan, there are only a few studies using representative surveys, and the detailed realities of the asexual population are yet to be explored. This article analyzed a web survey “Aromantic/Asexual Spectrum Survey 2020,” conducted by the Aro/Ace Survey Executive Committee. Most of the respondents tended to be cisgender women, young people, and residents of the southern Kanto region. Many identified as aromantic and asexual, but some identified as other aro/ace identities. We also conducted an analysis on “nonsexual,” an identity category unique to Japan. While masturbation and sex drives were found in a certain number of asexual respondents, the proportion of those who would like to have sexual contact with others was particularly low among asexual respondents. We conclude that sexual contact with others has important implications for self-identification.
“Two bits less” after quantum-information conservation and their interpretation as “distinguishability / indistinguishability” and “classical / quantum”
Authors: Penchev Vasil Dinev
Published: June 2021

The paper investigates the understanding of quantum indistinguishability afterquantum information in comparison with the “classical” quantum mechanics based on theseparable complex Hilbert space. The two oppositions, correspondingly “distinguishability/ indistinguishability” and “classical / quantum”, available implicitly in the concept of quantumindistinguishability can be interpreted as two “missing” bits of classical information, whichare to be added after teleportation of quantum information to be restored the initial stateunambiguously. That new understanding of quantum indistinguishability is linked to thedistinction of classical (Maxwell-Boltzmann) versus quantum (either Fermi-Dirac orBose-Einstein) statistics. The latter can be generalized to classes of wave functions (“empty” qubits) and represented exhaustively in Hilbert arithmetic therefore connectible to the foundations of mathematics, more precisely, to the interrelations of propositional logic and set theory sharing the structure of Boolean algebra and two anti-isometric copies of Peano arithmetic.

Social Media Posts Popularity Prediction During Long-Running Live Events A case study on Fashion Week
Authors: Sabet Alireza Javadian
Published: June 2021

In the last few years, social media has dominated various aspects of people’s life including social events. Users participate more and more in long-running periodical events in social media, by sharing their experiences and preferences. This information provides unprecedented opportunities allowing businesses to promote their brands coverage by using word-of-mouth (WOM), that is enabled by the user generated contents (UGCs). Studying social media content popularity by considering the societies’ behavioral patterns is, therefore, paramount. In this thesis, we inspect users’ engagement motives in long-running events by means of a comprehensive statistical analysis of fashion week events on Instagram. Additionally, we develop a multi-modal approach to solve the problem of post popularity prediction that exploits potentially influential factors and apply it on fashion week events. We employ two metrics for implementing a filter feature selection technique, together with an automated grid search for optimizing hyper-parameters in four regression methods: ridge, support vector regressor, gradient tree boosting and neural networks.

Published: June 2021

Objetivo: establecer la efectividad de la acupuntura en el control de los síntomas de la menopausia. Materiales y métodos: se seleccionaron menopaúsicas sanas entre 48 y 57 años que presentaban síntomas relacionados con la menopausia que no recibían terapia hormonal. El tratamiento consistió en 24 sesiones de acupuntura y se evaluó la intensidad de los síntomas con el puntaje del índice de Kupperman antes de iniciar y a las 4 y 8 semanas después de iniciadas las sesiones de acupuntura. Resultados: en 50 menopáusicas con edad promedio de 53,4 +/- 3,2 años después de 4 y 8 semanas de tratamiento no se observaron diferencias estadísticamente significativas en la intensidad de calorones, sudoración, trastorno del sueño, depresión, vértigo, cefalea, artralgia, palpitaciones, debilidad y síntomas vaginales (p = ns). El valor promedio de índice de Kupperman inicial fue de 30,6 +/- 4,7 puntos, el cual aumentó a 32,1 +/- 5,6 puntos a las cuatro semanas para luego alcanzar un valor de 31,1 +/- 4,8 puntos a las 8 semanas. No se demostraron diferencias significativas en los valores promedio de la escala a las 4 (p = 0,150) y 8 semanas (p = 0,596). Conclusión: la acupuntura no es efectiva para controlar los síntomas causados por la menopausia, por lo que no es una alternativa de la terapia de reemplazo hormonal.
Ensuring Safe Cyberspace for Children: An Analysis of The Legal Implications of Social Media Usage in Malaysia and Singapore
Authors: Md. Zahidul Islam  , Sonny Zulhuda  , Mohd Badrol Afandi Nor Hafizah , Mohamed Affan Shafy
Published: June 2021

Easy accessibility of electronic devices connected to the internet and the widespread usage of the internet in every aspect of modern lives have made the use of social media an indispensable part of society. These technologically driven and completely-internet dependence means of living have brought detrimental implications as much as they have benefited lives. Each day more and more children are introduced to the internet and its benefits, either at home as a means of entertainment, or at school as a means of education. However, these opportunities provide avenues for the children to explore the ever-expanding vastness of the internet, leading to exposure of indecent materials, and accessing and participating in websites not meant for the usage by underage children. The glorification of social media websites through targeted advertisements and peer pressure adds to the already worsening crises of social media abuse through unlawful means. This article examines the protective measures taken by the authorities in Malaysia and Singapore to protect children in these two countries from the internet and social media related issues. The data is acquired doctrinally from library sources and the finding of this article could be extended to other areas of protecting young children from the harms of the internet.
“MONEY MATTERS”; DIVIDING BUSINESS INTERESTS ON DIVORCE OR DISSOLUTION: SPECIAL REFERENCE TO THE BUSINESS ENTITIES
Authors: Norliah Ibrahim  , Zuhairah Ariff Abdul Ghadas  , Roslina Che Soh
Published: June 2021

In Malaysia, the contribution test is applied by both the Civil and Shariah courts to determine claims in business interest as matrimonial property. However, it is observed that different from claims on interest in personal property, the courts have to apply additional test other than the contribution test in determining claims of matrimonial property in business interest. This is because the ownership structure in business are different from ownership of personal property and highly dependents on types of the business entities.  Apart from analyzing the approaches adopted in the Malaysian courts in dividing business interest upon divorce or dissolution of marriage, this research also highlights the arising legal issues which may arise in respect of different business entities in which the business interest exists. This study was conducted primarily through a doctrinal study of existing literature such as articles, journals and the decision from the relevant case laws which was decided in both the Civil and Shariah courts. This research found that other than types of business entities, the interest of parties in business is also determined by the quantum of shareholding or contribution in the business.

Introduction: Smoking tobacco has been a longstanding issue worldwide, but the trend of smoking electronic cigarette (e-cigarette) is now on the rise. Many people have the view that smoking e-cigarette is safer and less harmful, and this is worrying. Adolescents and young adults are easily influenced by advertisements on e-cigarette. Thus, this study was conducted to determine the knowledge, attitude, and practice on e-cigarette among university students. Materials and methods: A cross-sectional study using self-administered questionnaire among 484 university students was carried out in a public university in Negeri Sembilan, Malaysia. Results: Respondents were 19 to 25 years old undergraduates, with the majority being female. In terms of smoking status, 32 (6.6%) of them were smokers, with only nine have ever tried e-cigarette, and only one being a regular user. Bivariate analysis showed knowledge, attitude and practices score on e-cigarette were correlated. Statistically significant associations were found between knowledge score and gender (p<0.001), while attitude and practice scores were associated with gender (p<0.001), household income (p = 0.013 and p = 0.001 respectively), as well as smoking status (p<0.001). Multivariate analysis revealed that being female and being a non-smoker were associated with higher attitude and practice scores. Conclusion: In conclusion, the awareness on e-cigarette needs to be improved among young adults and a more holistic intervention strategy should be implemented to prevent the rise of e-cigarette smoking.

Analisis Miskonsepsi Siswa pada Materi Bangun Datar dan Bangun Ruang
Authors: Fajari Urip Nurul
Published: June 2021

Matematika merupakan bidang studi yang memegang peranan penting dalam pendidikan. Geometri adalah salah satu materi dari matematika yang diajarkan di sekolah dasar. Geometri sering dianggap sebagai materi yang paling sulit dipahami karena memiliki istilah-istilah yang tidak mudah untuk dipahami. Permasalahan geometri yang paling sering muncul di sekolah dasar adalah miskonsepsi. Penelitian ini bertujuan untuk menganalisis miskonsepsi siswa pada materi bangun datar dan bangun ruang, penyebab, dan solusi penanganannya. Penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif eksploratif. Subjek penelitian ini adalah 56 siswa siswa kelas 5 SDN 2 Karangreja dan SDN 1 Sirandu. Hasil penelitian menunjukkan bahwa siswa mengalami miskonsepsi pada materi: (1) posisi posisi segiempat, istilah segiempat, dan hubungan antar bentuk-bentuk segiempat; (2) istilah luas daerah bangun datar; (3) alas prisma; (4) garis tinggi limas; (5) sisi balok; dan (6) rusuk kerucut. Miskonsepsi siswa disebabkan oleh beberapa faktor, yaitu (1) penjelasan guru yang tidak menyeluruh; (2) siswa belum memahami istilah-istilah dasar seperti sisi, rusuk, dll.; (3) siswa terbiasa dengan posisi bangun datar atau bangun ruang yang horizontal; (4) pembelajaran tanpa visualisasi benda konkret. Adapun solusi penanganannya adalah dengan menggunakan media pembelajaran yang konkret dan menarik, dan menjelaskan perbedaan istilah-istilah bangun datar maupun bangun ruang secara menyeluruh.

 

Mathematics is a field of study that plays an important role in education. Geometry is one of the materials from mathematics taught in elementary schools. Geometry is often considered the most difficult material to understand because it has terms that are not easy to understand. The most common geometry problem that arises in elementary schools is misconception. This study aims to analyze students' misconceptions on two-dimensional figure material and geometry, their causes, and their handling solutions. The research method used is qualitative with a descriptive exploratory approach. The subjects of this study were 56 fifth grade students of SDN 2 Karangreja and SDN 1 Sirandu. The results showed that there were students' misconceptions on the material: (1) quadrilateral positions, quadrilateral terms, and relationships between quadrilateral forms; (2) the term area of ​​a two-dimensional figure; (3) the base of the prism; (4) pyramid altitude; (5) cuboid side; and (6) cone edge. Student misconceptions are caused by several factors, namely (1) incomplete teacher explanation; (2) students have not yet understood basic terms such as sides, edges, etc.; (3) students are accustomed to horizontal two-dimensional figure or geometry positions; (4) learning without visualization of concrete objects. The solution is to use concrete and interesting learning media, and explain the differences in terms of two-dimensional figures and geometry as a whole.

Modern ethnocultural processes taking place among the indigenous peoples of the northern and Arctic territories, the current state and issues of broadcasting and preserving their ethnic identity are one of the topical research topics of the world scientific community. The attention to the Ket ethnocultural group is justified by its uniqueness as the last representatives of the Yenisei group of peoples. Research immersion into the foundations of the formation of the modern ethnocultural image of the Kets, including in the information and media space, reveals the need to refer to the cultural memory of the Kets, the basic foundations of their ethnocultural identification. Thus, the study of the representation of Kets in the media space makes it possible to fix the modern information image and visualization features of the Ket ethnocultural group.

This article presents the results of the analysis of the concept of "modern information environment", and also defines its place in the ethno-cultural space. The purpose of the analysis is to study the influence of modern information processes on the traditional musical folklore culture of the small peoples of Siberia. On the materials of field research and the study of online communities, created ethnic groups, the analysis of the influence of "modern information environment" for the life of the indigenous peoples of Siberia. Also, the characteristic features of musical folklore are determined by the example of the analysis of interviews taken from representatives of such ethnic groups as Dolgan, Ents, Nenets. A study of recordings of ethnic festivals and TV shows that promote the popularization of folk song art of the small peoples of Siberia was conducted. The analysis methods used made it possible to formulate the value and semantic meaning of musical folklore culture for the life of a modern person, to determine the place of musical culture in the "modern information environment", as well as to trace cross-cultural ethnic ties. As a result of the analysis of the information space, the following was revealed: first, thanks to information resources, traditional and modern musical culture goes beyond territorial borders and becomes accessible to an audience from different regions of the country and not only; secondly, the broadcast of musical art in online mode allows for the inclusion of the largest number of performers of national music in this process.

Genomic regions encoding 5S ribosomal RNA represent a convenient source of molecular markers. These genomic regions are composed of tandemly organized repeated units. Each unit consists of a highly conserved 5S rRNA coding region and a variable intergenic spacer (IGS). Within the IGS, regulatory elements involved in 5S rDNA transcription are located. Given that 5S rDNA is present in the genomes of all eukaryotes, this region can be used as a universal model to study molecular evolution in different taxa. Molecular studies of Lepidoptera have always been of considerable practical interest, because this group includes a large number of crop pests. Accordingly, the results of molecular studies can be used for molecular genotyping and correct identification of insect pests. Taking into account that the molecular organization and polymorphism of 5S rDNA remain still unexplored in species of the Drepanidae family, the aim of our work was to investigate the 5S rDNA of peach blossom (Thyatira batis L.), a representative of this family. The repeated unit of 5S rDNA was amplified by PCR, and the obtained DNA fragments were ligated into a plasmid vector. Plasmids containing the inserts were sequenced. It was found that two variants of IGS, 75- and 120-bp-long, respectively, are present in the 5S rDNA of T. batis, and the level of similarity between them amounts to 32% only. Therefore, T. batis possess the smallest size of the 5S rDNA IGS among all lepidopterans studied to date. Within the IGS, several variants of microsatellite sequences were found. In the long variant of the IGS in the position -22 bp a TATA-like motif was identified, which may be involved in transcription initiation, whereas in the short variant of the IGS this motif was lost due to deletion.

The article focuses on the possibility of applying the green alga Chlorella vulgaris Beijer. culture to bioremediation activities. Two types of wastewater were simulated, agricultural (ACW) and domestic (DW). The experiment was conducted under laboratory conditions in 500-ml Erlenmeyer flasks. The ratio of the amount of the algal culture and the wastewater volume was 1:10. The content of NO3-, NO2-and NH4+ in the composition of the wastewater was tested before and after cultivating the alga; during cultivation, the pH of the culture medium and the optical density of the Ch. vulgaris culture were monitored. The indicators of the amount of various forms of nitrogen and the pH level show that simulated domestic and agricultural wastewater can serve as an alternative nutrient medium for growing green algae. The use of Ch. vulgaris for the treatment of domestic and agricultural effluents allows avoiding almost completely their nitrate and ammonia pollution. The amount of biomass obtained within 25 days of cultivating Ch. vulgaris on agricultural sewage was two times higher than in the control Tamiya medium. Resulting Ch. vulgaris algal mass with the proteins content of 55% and lipids reaching 30% can match various needs being used a source of protein or lipids.

The study is dedicated to the investigation of the chitosan influence of diverse origin, molecular mass and deacetylation degree on the dynamics of both garden strawberries' phylloplane and rhizosphere aspectual composition. It was defined that Chitosans carry a varied impact on the fungal groups of both Fragaria ananassa phylloplanes' and rhizospheres', as evidenced by the dynamics of their species composition, changes in the population level and occurrence frequency. Namely, the chitosan forms under investigation had a stimulant effect on both micromycetes' and phylloplanes' dominant genus, causing an increase in strawberry leaves' population level after treatment. Nevertheless, the epiphytic fungi species structure of garden strawberry differed 48 hours after treatment with low molecular weight (LMW) and high molecular weight (HMW) chitosan solutions. It has been demonstrated that the rhizosphere mycobiota possesses different sensitivity to LMW and HMW solutions. The greatest inhibitory effect of chitosan forms was observed on penicillium, the soil CFU number of which was less compared to the control one. Thus, the Penicillium sp. amount was 47.4 thousand CFU/g of soil before treatment, becoming 4.9 and 6.3 thousand CFU/g of soil after the low molecular weight chitosan application — 12 and 48 hours after application, accordingly. On the contrary, an increase in abundance in all application variants was observed for the Fusarium genus. This can be explained by the fact that Fusarium genus fungi in the soil are predominantly in the form of mycelium hyphae, being more resistant to chitosan. As a matter of record both incubation time and the environment into which chitosan is put are no less important for its effectiveness except for physiological activity and functional properties, depending on molecular weight.

The results of the syntaxonomical and ecological studies on plant cover at the landscape reserve «Tsetsyno» located within administrative boundaries of the city of Chernivtsi, are presented. Forest vegetation belongs to 3 associations, 2 alliances, 2 orders of the class Carpino-Fagetea sylvaticae Jakucs ex Passarge 1968. According to the synphytoindicational analysis, these communities are mesophytic, hemihydrocontrastophobic, subacidophilous, semieutrophic, nitrophilous, and hemiaerobic. In study area, communities belong to the alliance Fagion sylvaticae Luquet 1926 are prevail, and communities of the alliance Tilio-Acerion Klika 1955 are much rare. Two habitat types listed in Annex 1 of the Habitats Directive (9130 Asperulo-Fagetum beech forests and 9180*Tilio-Acerion forests of slopes, screes and ravines), аs well as one habitat listed in Resolution 4 of the Bern Convention (G1.6: Fagus woodland), are distinguished here. Moreover, 5 rare plant communities according to the Green Book of Ukraine (2009), are reported. Among vascular plants, 8 species belong to CITES, 1 species (Cypripedium calceolus L.) – to the Annex I of the Bern Convention, and 11 species – to the Red Data Book of Ukraine (2009). This landscape reserve is consider as an Important Plant Area (IPA) – Tsetsyno and is a part of the regional landscape park «Chernivetskyi» (Emerald Network Area UA 0000085). The results obtained confirm significant sozological value of the landscape reserve.
