Published: May 2023

Oral health is considered as important part of general health. Dental caries and periodon-tal diseases are among most prevalent diseases worldwide. According to WHO oral dis-eases affect nearly 3.5 billion people and untreated dental caries is the most common health condition. Young adults may neglect oral health. The aim of our study was to eval-uate oral health status (dental caries and periodontal diseases) among medical students at European University affiliated dental clinics in Georgia. Simple random sampling method was used. Assessment was conducted using modified WHO Oral Health Assessment Form (2013). Study sample were medical undergraduate students aged between 17 and 25 years at the European University - affiliated dental clinics, Tbilisi, Georgia. Level of dental caries was evaluated by assessment of decayed, missing, and filled teeth scores (DMFT in-dex), while periodontal status was assessed using Community Periodontal Index (CPI) modified index. Statistical analysis of data was performed. Results: Totally 225 students (150 males and 75 females) originally from Georgia, Jordan, Iran, Egypt, Great Britain and Sweden were included in the study. Mean age of participants was 20.7 years. Mean DMFT score in males was 3.11 and in females it was 3.25; overall mean DMFT was 3.18. Percentage of all individuals in two groups with dental caries (DFT ≥ 1) was 84%. Mean CPI index was 0.82 in males and 0.75 in females. Mean DMFT were compared to National estimates for DMFT index for same age group in developed coun-tries. Conclusion: Study showed medium prevalence of caries and low prevalence of periodontal diseases in participant students. Keywords: Oral health, DMFT index, CPI index
Successful Second Intention Healing of a Large Skin Wound in a Cat's Cheek Using Manuka Honey
Authors: Kail Paul AC
Published: May 2023

A recent case report (Lukanc et al., 2020) demonstrated successful second-intention heal-ing of a large skin wound on a cat’s leg. The wound was treated with honey to kill path-ogens, stimulate the immune response and keep the wound moist. The present case re-port complements this result by showing a similar result in a different part of the body. The subject presented with a burst abscess which left 42-45 square cm of necrotic skin on the side of his cheek. The wound healed over a period of two months through a combina-tion of new skin regeneration and the stretching of existing skin. As a result of this, eu-thanasia was avoided and the patient made a full recovery. The case report details stages in the recovery process and discusses the challenges of protecting the wound while still allowing the patient to experience a reasonable quality of life.

Circular Economy in Supply Chain
Authors: Singh Rajat
Published: May 2023

A resource management strategy known as the circular economy in the supply chain aims to minimise waste and advance sustainability by extending the useful life of commodities. Using circular economy principles in the supply chain can have a big influence on the bottom line, the environment, and overall supply chain resilience. Yet other issues need to be resolved, like a lack of resources and knowledge, convoluted supply networks, and legal restrictions. Despite these obstacles, the supply chain is home to numerous circular economy projects, such as closed-loop supply chains, remanufacturing, and sustainable packaging. We may anticipate that the circular economy will continue to expand as companies, governments, and consumers learn more about its advantages.
Analysis of Screen Based Activity on Digital Eye Strain in School-Age Children in Peniwen Village, Malang, East Java
Authors: Minarni Wartiningsih
Published: April 2023

Introduction: The use of digital devices has increased across all age groups and professional fields, making them inseparable from everyday life. This increase in the duration of screen-based activities causes various symptoms of eye health problems. This study aimed to determine the prediction of the relationship and influence between Screen-Based Activity (SBA) and the incidence of Digital Eye Syndrome (DES) in children aged 9-12 years in Peniwen Village, Malang.
Material and Methods: This study used a cross-sectional analytical observational design. There were 62 respondents in the research samples, or the same number as the total population. The analysis technique used in this study is the Partial Leas Square (PLS) modeling technique with testing using software such as SmartPLS (v3.2.9).
Results: Based on the results of the analysis, obtained t-count (23.821) is greater than the t-table (1.96), meaning that there is a relationship and influence between SBA variables on DES. The correlation coefficient of SBA to DES is positive 0.818 which means the higher the Screen Based Activity, the higher the risk of Digital Eye Strain. The use of handphone (X2) is an indicator of SBA with the highest correlation strength of 88.1%.
Conclusion: There is an association between the duration of Screen Based Activity and the incidence of Digital Eye Strain in children. The higher the Screen Based Activity, the higher the risk of Digital Eye Strain. In addition, the use of handphones has the highest correlation in influencing the occurrence of Digital Eye Strain in school-age children in Peniwen Village.
Pedagogical Benefits and Practical Concerns of Writing Portfolio Assessment: Suggestions for Teaching L2 Writing
Authors:   Murray State University, Do Hieu Manh
Published: May 2023

This study aims to investigate Vietnamese students’ perceptions of portfolio assessment and how it affects their writing performance. Furthermore, the study explores problems encountered during the assessment process, which could offer professional support for teachers, particularly novice teachers, when applying this formative assessment to teaching writing. Data was collected through students’ written papers, observations, and semi-structured interviews with a total of thirteen low- and intermediate-level undergraduate students. The findings demonstrate the aspects of the assessment usefulness, namely validity, authenticity, interactive-ness, and impact. Accordingly, the assessment provides students with a comprehensive understanding of academic writing that enhances their writing abilities. In particular, students recognize their common grammatical errors, pay more attention to organizing ideas logically, and develop writing habits throughout the writing process, which have not been carefully addressed in prior education. Nevertheless, there are a number of issues that need to be carefully considered, including idea development, plagiarism knowledge, self- and peer-assessment, and the order of writing steps. In order to improve the reliability and practicality of the assessment, solutions to those concerns are provided.
Core Academic Vocabulary in Four Genres of Novice Student Writing
Authors:   The Open University, UK, Therova Dana
Published: May 2023

Since written assignments often constitute the main form of assessment in tertiary education, academic writing skills are of paramount importance to university students. The role of academic writing in turn emphasises two aspects vital for successful written production at universities: genre awareness as students are assessed on the production of relevant genres and the use of academic vocabulary regarded as a key element of academic writing style. This study employs a corpus-based approach to explore the usage of academic vocabulary in four genres of assessed academic writing produced by multilingual foundation-level students (N=193) at a UK university. The findings show that in all writing genres there was a small set of core academic vocabulary used by the majority of students in their written assignments, accounting on average for approximately 3.6% - 9% of academic vocabulary types across the genres under investigation. In addition, differences were found in the distribution and function of the core academic vocabulary items across genres. These findings have potentially important pedagogical implications for English for Academic Purposes (EAP) contexts catering for novice student writers.
TESOL Teacher Education in a Transnational World: Turning Challenges into Innovative Prospects [Review]
Authors:   University of Glasgow, Wright Natalia
Published: May 2023

[Initial paragraphs] TESOL teacher education is, at its core, a set of practices that involve collaboration and interaction among individuals from various cultural, linguistic, and national backgrounds. It could be argued that its transnational aspect is a defining feature, which has become increasingly apparent in recent years. Transnationalism can be broadly understood as a process and practice of maintaining multiple connections between individuals and institutions that span nation-state borders (Vertovec, 2009). With English playing a pivotal role in mediating and shaping these connections, language educators have the responsibility to prepare students for participation in a globalized world with an awareness of its cultural and linguistic diversity. This raises a set of challenging questions about how transnationalism affects teacher knowledge formation, how teachers understand their work in the context of transnationalism, and what TESOL teacher education can do to prepare teachers for the challenges of transnational work. The book TESOL Teacher Education in a Transnational World: Turning Challenges into Innovative Prospects, edited by Osman Z. Barnawi and Anwar Ahmed, is a timely response to these questions. In addressing them, the editors bring together the diverse perspectives of scholars on the complexities of transnationalism in relation to teacher education.

Published: April 2023

Armed aggression and its negative impact on the exogenous and endogenous environment of economic agents aggravate the problems of the sectors of the national economy, in particular, the banking sector. In this context, the state acquires a key role in managing the processes of the banking sector at both the micro and macro levels. The aim of the article is to determine the key characteristics of the state’s influence on the banking sector in Ukraine during the active phase of the war. The method of synthesis, the method of economic and statistical analysis, and the case method were applied for the analysis. The methodological framework of the research is the method of strategic analysis. The key task of balancing the operational work of the banking sector, maintaining a stable macroeconomic condition and state security is emphasized. As a result, emphasis is placed on the need to define a system of key indicators for management by the regulator and central authorities during the war. Accordingly, the analysis of these indicators showed that the banking sector of Ukraine did not experience catastrophic losses in 2022, which indicates the success of the state in this area. In particular, the number of operating banks in Ukraine slightly decreased by -5.7% in 2022 to 67 banks. Moreover, it was recorded that the banking sector of Ukraine maintained a positive financial result at the level of UAH 12 billion net profit in Q3 2022. Prospects for future research consist of an in-depth study of factors influencing the complex of state actions at the micro- and macro-levels in terms of meeting the needs of the main groups of stakeholders.

Authors: Yankovoi Roman
Published: April 2023

The article substantiates the need to diagnose the state of innovative development of enterprises in Kyiv. It is determined that the solution to the problems of destabilization of enterprises is seen primarily in the formation of a system of conceptual foundations for ensuring innovative development and its diagnostics. The prerequisites for diagnosing the innovative development of enterprises in the city of Kyiv are determined: lack of conditions for effective innovative development of enterprises in the current globalization environment; the need to develop a scientifically sound conceptual framework for diagnosing the status of enterprises; the need to develop appropriate mechanisms to support and manage the innovative development of enterprises in the city of Kyiv. The author proposes a methodology for assessing the innovative development of enterprises based on the criteria of business performance, namely: the ability of enterprises to optimally allocate and efficiently use resources (resource component); social component; market component; innovation component. Various scientific studies on the problem of diagnosing the innovative development of enterprises in Kyiv have been summarized, which allowed to distinguish two main methods of calculating: Euclidean metric, which allows for each indicator of innovative development of enterprises; on the basis of the second method, it is advisable to make a comparison for each presented functional component of the innovative development of enterprises in Kyiv and assess its contribution to the overall level of development. The key feature of assessing the level of innovative development of enterprises to the presented algorithm is that its practical implementation allows to satisfy the interests of both enterprises in the city of Kyiv and their constituent sub-levels.

The purpose of the article is to study the factors of the development of enterprises in the tourism industry of Ukraine and the formation of scenarios for their development in the conditions of martial law and after the end of hostilities. When conducting the research, the methods generally accepted in economic science were used: monographic, dialectical - in the process of researching the development of enterprises of the tourism industry of Ukraine under martial law and after the end of hostilities; analysis and synthesis, grouping - to determine the factors of development of tourism industry enterprises; generalization and analysis, economic-statistical, abstract-logical and system-structural - for the formation of scenarios for the development of enterprises of the tourism industry of Ukraine. The key problem of the study is russia's attack on Ukraine, which turned into a heavy blow to the country's tourism. The article proves that protectionism and international conflicts threaten freedom and freedom to travel. All these changes mean that we are going through a period of great destabilization. It is justified that the reality as we know it, with a Europe without border crossings, may soon disappear. Emphasis is placed on the fact that it is important to create such tourist programs now so that not only Ukrainians but also tourists from other countries understand what was happening in Ukraine and tell about the struggle of Ukraine. Four scenarios for tourism development in Ukraine have been proposed, each with a number of implications for stakeholders. Based on the conducted scientific research, it was concluded that one of the optimal approaches to the formation of scenarios for the development of tourism industry enterprises in Ukraine in the conditions of universal dynamism, unpredictability and variability of the business environment is recognized as strategic management and change management. The practical significance of the obtained results reveals the prospects for applying the main scientific provisions of the article in the practice of managing tourism business enterprises in Ukraine in the conditions of post-war reconstruction. The results of the study presented in the work can be used by economists, scientists and practitioners to implement scenarios for the development of tourism industry enterprises in Ukraine, each of which has a number of consequences for stakeholders.

Published: April 2023

The purpose of the article is to study the theoretical foundations and practical aspects of legal regulation of the mechanism of applying blockchain technology in the modern conditions of digitalization of the economy of Ukraine. The results of the conducted research give reasons to state that the legal regulation of the mechanism of applying blockchain technology in the modern conditions of digitalization of the economy of Ukraine is too weak and needs to be revised and improved. The article defines the essence of blockchain technology, which is understood as a decentralized database formed by participants and provides conditions for preventing actions related to the falsification of data due to their chronological recording and public confirmation by all participants of the transaction network. On the basis of a detailed study of the outlined issues, significant problematic aspects of the use of blockchain technology at the global, national and regional levels have been identified, the most acute of which at the current stage is the imperfection of the legal mechanism of applying blockchain technology in the modern conditions of digitalization of the economy. The results of empirical studies have proved the dependence of the development of blockchain technology on the level of development of the country and the state of the digitalization process of the national economy. It has been established that the highest share of the use of blockchain technologies in today's conditions is observed in the USA (40%) and Great Britain (17%). In order to solve problematic issues, the main areas of improving the legal regulation of the mechanism of applying blockchain technology in Ukraine are proposed, among which the need for the development and adoption of the Law of Ukraine "On Virtual Assets" is justified, as well as the need for the implementation of international and European law in the field of digitalization and regulation of the development of digital technologies in the national legislation of Ukraine.

Published: April 2023

Початок російсько-української війни спричинив потужну хвилю міграції українців до Західної Європи. Затяжний характер війни та можливість соціалізуватися в країнах ЄС сформували в частини українських біженців бажання не повертатися в Україну, що створює дефіцит робочої сили, на яку уряд покладає великі надії в повоєнному відновленні економіки. Метою роботи є дослідження структури, динаміки та причин вимушеної зовнішньої міграції з Україні у 2022 році й подальшої рееміграції, окреслення дієвих заходів щодо повернення вимушених мігрантів. Для емпіричного дослідження динаміки та структури міграційних процесів за досліджуваний період були опрацьовані дані UNHCR. Системний аналіз дозволив обґрунтувати теоретико-методологічні засади та закономірності формування політики рееміграції в Україні, а метод експертних оцінок – оцінити вплив зовнішніх міграцій, викликаних воєнними діями в Україні, на соціально-економічний розвиток. Аналіз причин міграції та рееміграції українців у 2022 р. дозволяє стверджувати, що причини рееміграції набагато вагоміші. Це дає підстави стверджувати, що більшість українських мігрантів після закінчення війни повернуться в Україну, якщо урядом будуть запроваджені державні програми із забезпечення житлом реемігрантів, які втратили житло через війну: пільгові умови оренди приміщень, побудова багатофункціональних поселень із належними екологічними умовами на місцях монофункціональних поселень, державна фінансова підтримка та створення нових робочих місць. При цьому автори прогнозують нерівномірність заселення України, коли більш населеними будуть західні та центральні регіони держави. Найбільшим викликом для уряду буде повернення висококваліфікованих українців з високим рівнем адаптації до іншої культури, які володіють іноземними мовами, ІТ-технологіями і в послугах яких украй зацікавлені країни ЄС. Для цієї категорії мігрантів потрібні ще додатково спрощені процедури відкриття бізнесу та широка інформаційна кампанія, яка сформує впевненість в успішному бізнесі в Україні.
CAPITAL STRUCTURE AS A CRITERION OF EFFICIENT MANAGEMENT OF THE CORPORATION'S FINANCIAL RECOURSES
Authors: Hrynyuk Nataliya , Dokiienko Larysa , Levchenko Valentyna , Trynchuk Viktor
Published: April 2023

The article presents an approach to the corporation's capital structure management based on the criterion of maximizing the return on equity (ROE). The basis of this approach is the determination of the expediency of attracting borrowed resources from the point of view of balancing financial risk and profitability. The toolkit for optimizing the capital structure of the corporation is substantiated, taking into account the indicator of financial leverage, which ensures the most effective proportionality between profitability and financial stability. An algorithm for determining the level of financial risk in the structure of the interest rate for attracting borrowed resources has been developed, which involves the formation of the amount of the premium for the risk of insolvency of the borrower and the corresponding methodology for determining the position of the borrower on the scale "financial stability–solvency–financial risk". The post-optimization multifactor sensitivity analysis of the proposed capital structure optimization model made it possible to establish certain patterns regarding changes in ROE and its components.

Published: April 2023

Due to a number of external uncontrolled factors of negative influence, Ukrainian business entities functioning in the hospitality and tourism business have seen the most severe crisis and depression over the past three years. In order to survive in such conditions and develop the business intensively, Ukrainian business entities must clearly define internal problematic aspects to correct them promptly, as well as the potential opportunities towards which the maximum effort should be directed. The article offers and justifies an approach to assessing the financial and economic security of hospitality and tourism business entities in the complex modern conditions under which the Ukrainian economy is developing. In order to achieve the research goal, the methods of systematization, grouping, and logical generalization were applied.The article systematizes the key aspects of ensuring the financial and economic security for the company's activities that should be followed by its management, describes the structure of an enterprise's financial and economic security, and formulates the concept of financial and economic security for business entities in hospitality and tourism. The paper also specifies the sequence of stages, which would be advisable to follow when managing the financial and economic security of hospitality and tourism enterprises. The authors have summarized the approaches to assessing an enterprise's financial and economic security in modern literature and have grouped the indicators of financial and economic security for hospitality and tourism business enterprises. The study analyzes the dynamics of financial indicators which comprehensively characterize the functioning of temporary accommodation and catering enterprises, as well as economic operators of tourist activity in Ukraine and offers an approach to assessing the financial and economic security of hospitality and tourism business enterprises which base their activities on the innovation potential. The results of the study prove that differentiating and operating the components of hospitality and tourism business operators' innovation potential is expedient and improves their financial and economic security.The practical significance of the obtained results lies in increasing the financial and economic security and innovativeness of hospitality and tourism business enterprises in Ukraine by applying the proposed approach to evaluation as a monitoring tool.

Published: April 2023

The increasing level of population coverage with housing has traditionally been among the most relevant and challenging issues for the national economy of Ukraine. The military conflict, now in its second year, is changing the priorities of the public housing policy and requiring the search for new efficient methods of restoring the lost housing stock and regulating housing construction. The article addresses the volume of capital investment in residential construction in Ukraine and explains the financial framework for residential construction regulation. World best practices in the use of financial instruments in the regulation of the industry are systematized. The authors' view of the system of financial leverage of residential construction regulation is offered. The analysis of the housing affordability indicators shows that the average household income is insufficient to purchase housing and repay a mortgage. Meanwhile, the research indicates that a mortgage is one of the most common financial instruments for the purchase of housing for Ukrainians. The analysis of the level and dynamics of mortgage interest rates shows that they are 4.6 times higher in the euro than in the EU countries. The study of modern housing practices in Ukraine emphasizes the need to introduce new principles of sustainable financial regulation in residential construction. The article substantiates a set of these principles and recommends their implementation. The assessment of modern realities and consequences of hostilities in Ukraine reveals significant losses of housing stock (about 40%) and the need to change the priorities and tasks of public housing policy. An examination of the country's recovery and post-war housing programs allows the identification of the principles of transparency, openness, inclusivity, energy efficiency, resource efficiency, and sustainability as key strategic priorities in financial regulation.
MELODIC CONTOUR OF YES-NO QUESTION IN WESTERN MIDDLE-RUSSIAN DIALECT WITH AKAN’JEPART I: SELIGER-TORZHOK DIALECT
Authors: KNYAZEV SERGEY , DYACHENKO SVETLANA V.
Published: May 2023

This paper deals with the intonation of yes-no question in Western Middle-Russian dialect with akan’je spoken in Vyshny Volochek district of Tver region. The study, based on the material of dialectal speech recordings made in the 2017 (eight speakers born in 1926-1952, total duration - 9,5 hours), reveals that the melodic contour of yes-no question in Western Middle-Russian dialect occupies an intermediate position between corresponding tonal structures of Modern Standard Russian and those of Northern Russian dialects: while sharing rising pitch associated with the accented syllable and falling tone on the postaccented ones, it differs 1) from the Standard Russian owing to earlier timing of the pitch accent (with the maximum tonal point around the middle of the stressed vowel rather than at the end of the stressed syllable for the Standard variety) and the absence of truncation of the falling tune and 2) from the Northern one - due to the absence of high phrase tone on postaccented syllables. Th e difference from Western Middle-Russian dialects with okan’je lays in the domain of pretonic syllable which bears a “falling set-up”. We thus suggest the interpretation of %L L+H* L-L% for Western Middle-Russian dialects with akan’je.

Published: April 2023

The Kamenka River ows through the territory of the Kokuyskoye gas and oil eld located in the Perm Territory. Despite the absence of oil-producing facilities in the immediate vicinity of the river, oil hydrocarbons were found in the waters and bottom sediments at a concentration of 2445-25800 mg/kg. The composition of microbial communities of bottom sediments of the Kamenka River, located at the source and along the river, was studied. Using the methods of high-performance sequencing and bioinformatic data processing, it was established that the main share of microbial communities is represented by bacteria of the phylum Proteobacteria (16.7-30.3%), as well as the phyla Actinobacteriota, Bacteroidota, Bdellovibrionota, Campilobacterota, Chloro exi, Cyanobacteria, Deferribacterota, Desulfobacterota, Firmicutes, Gemmatimonadota, Methylomirabilota, Myxococcota, Nitrospirota, Patescibacteria, Planctomycetota, Spirochaetota, Synergistota, Thermotofota and Verrucomicrobiota. The values of the Shannon index for the studied communities are directly correlated with the concentration of petroleum hydrocarbons in bottom sediments. The phylum Proteobacteria in communities is represented by the classes Alphaproteobacteria and Gammaproteobacteria, among which representatives of the families Rhodobacteriaceae and Comamonadaceae dominate. When identifying to the genus, it was found that in the Comamonadaceae family, the main share is made up of bacteria of the genus Hydrogenophaga. It should be noted that bacteria of the genus Pseudomonas (class Gammaproteobacteria) were found only in the microbiocenosis of bottom sediments, characterized by the highest concentration of petroleum hydrocarbons.

The present study on SSR marker-based genetic diversity and marker-trait association analysis in aromatic rice (Oryza sativa L.) landraces was carried out at R. H. Richharia Research Laboratory, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during 2020. A total of 25 PCR-based simple sequence repeats (SSR) markers were evaluated in a set of 90 aromatic rice landraces along with 6 checks which includes 1 non-aromatic and 5 aromatic check varieties. Phenotypic data for marker-trait association analysis were taken for 24 yield attributing traits. Polymorphic Information Content (PIC) value ranged from 0.52 (RM316) to 0.79 (RM553) with a mean of0.69 which reveals that all the markers used in this study were highly informative and useful for diversity analysis of a wide range of genotypes. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and Rho’s similarity based cluster analysis revealed that all 5 aromatic check varieties falls in one cluster while the 1 non-aromatic check variety (Mahamaya) forms a separate cluster. Mixed linear model (MLM) was applied to perform genome-wide association mapping where 41 significant marker-trait associations were observed for 24 yield attributing traits. The potential markers identified in the study may provide new opportunities for rice breeder to improve yield and its attributing traits through marker assisted selection approach.

Authors: Deniyatno Deniyatno , Armid Armid
Published: May 2023

Aktivitas pertambangan mengalami perkembangan yang sangat pesat di Provinsi Sulawesi Tenggara, termasuk wilayah Kabupaten Konawe Utara. Salah satu wilayah tambang di daerah ini terletak di Desa Boedingi, Lasolo Kepulauan. Studi ini dilakukan untuk mengkaji status kawasan laut di wilayah Desa Boedingi akibat aktivitas pertambangan. Sebanyak 2 titik sampel (AL-01 dan AL-02) ditetapkan untuk analisis air laut dan 3 titik (TK-01, TK-02 dan TK-03) untuk kajian kesehatan terumbu karang. Parameter fisik air laut diukur secara langsung saat sampling, sedangkan parameter kimia dianalisis menggunakan metode spektrofotometri. Pengamatan kondisi terumbu karang dilakukan dengan metode Line Intercept Transect (LIT). Hasil studi menunjukkan bahwa nilai TSS pada titik pengamatan lebih besar dibanding nilai ambang batas. Khusus titik AL-01, nilai TSS yang terukur (38,95 mg/L) hampir 2 kali lipat di atas nilai ambang batas (20 mg/L); kemungkinan hal ini disebabkan oleh peningkatan aliran permukaan pada lahan bukaan tambang yang masuk ke wilayah perairan laut. Nilai persentase terumbu karang hidup (life coral) sebesar 18,4%, 15,67%, dan 13,03%, masing-masing untuk titik pengamatan TK-01, TK-02, dan TK-03, termasuk dalam kategori buruk. Studi ini merekomendasikan kepada pemerintah Kabupaten Konawe Utara untuk melakukan pengawasan yang sitematis dalam upaya untuk menjaga kelestarian lingkungan laut sebagai dampak langsung dari kegiatan pertambangan di daerah ini.

Background. Pig farming is one of the most important livestock raised in Nigeria by smallholder farmers. Objective. To determine the breeding practices and breeding traits of preference by pig farmers in Nasarawa State, Nigeria. Methodology. A total of 120 pig rearers (62 males and 58 females) were randomly sampled. Primary data were collected through individual structured questionnaire administration. Chi square (χ2) statistics was used to compare categorical variables. Arithmetic means and their standard errors of continuous variables between gender were tested using T- Test. Ranking of the eight traits of preference (body size, body conformation, mothering ability, survival, heat tolerance, disease resistance, fertility and temperament) was carried out using the non-parametric Friedman Test (Wilcoxon Signed-rank test for post hoc analysis) as well as Kruskal–Wallis H Test (with Mann– Whitney U Test for means separation). Multivariate Clustering Analysis was also explored to group the farmers on gender basis. Results. The source as well as the number of foundation stock varied between the sexes (P= 0.048 and 0.028, respectively). Average flock size was higher (20.31±2.21 versus 14.78±1.53; P<0.05) where the pigs were under the management of male farmers. This reflected more in pigs of mixed genotypes compared to the indigenous ones. The number of piglets/sow/annum (14.77±0.77 versus 12.29±0.54; 16.36±0.76 versus 14.02±0.58; P ≤ 0.05) was also higher in flocks of male farmers for both indigenous pigs and those of mixed blood. Between-gender, all the preference traits were ranked similarly (P>0.05) apart from temperament which was more highly rated by the males. However, the multivariate analysis revealed that body size and body conformation were more associated with the female farmers while survival, disease resistance, heat tolerance, mothering ability and temperament were more preferred by their male counterparts. Implication. The traits of economic importance obtained in this study may guide future community-based pig genetic improvement programmes in a tropical environment. Conclusion. The present study revealed the importance of body size, body conformation, mothering ability, survival, heat tolerance, disease resistance and fertility in the selection of breeding pigs. However, these traits were differentially rated by male and female farmers.

Background. From the early days, human beings have used plants to satisfy their biological or cultural needs; this man-plant relationship is studied by ethnobotany. Pumpkins were one of the first plants domesticated by Homo sapiens and currently they are important species in human diet. Objective. To explore the knowledge about the relationship that exists between farmers and pumpkin species cultivated in Nayarit, Mexico. Methodology. Consisted of fieldwork in the years 2013 and 2014, where 15 municipalities were visited, and 35 farmers were interviewed; techniques used for the compilation of information were through semi-structured interviews and the participant observation method. Species studied were Cucurbita argyrosperma Huber, Cucurbita ficifolia Bouché, Cucurbita pepo L. and Cucurbita moschata Duch. Ex Lam. Information collected included the traditional classification, uses, selection criteria for seed, a source of knowledge acquisition of the crop and beliefs and rites related to the species. Results. Main use of pumpkin among farmers were as food, forage and medicine. Seeds and fruits were the main elements of interest; producers’ criteria for selection of plants are based on the characteristics of fruits using established patterns, with which they create their selections for fruit or seed production. Conclusion. It was found that Cucurbita spp. have a ritualistic relationship with the Huichol ethnic group, as it is part of their ceremonies related to their beliefs.

Background. Banana plants require large amounts of nutrients but fertilizer price is restrictive for many farmers, so it is important to develop technologies that support the productivity of banana crops relying on local nutrient sources by enhancing soil biological activity. Objective. To evaluate the feasibility of integrating the management of mycorrhizal inoculants, green manure and organo-mineral fertilization in banana. Methodology. Different treatments with compost and sugar cane straw ash as organo-mineral fertilizers, jack bean (Canavalia ensiformis) as preceding and intercropped green manure, and inoculation with Rhizoglomus irregulare (INCAM-11), were evaluated in banana cv. 'FHIA-18'. The experiment was planted on Calcic Haplic Phaeozems and conducted during the cycles of planting, first ratoon, and second ratoon. The experiment had a randomized complete block design with four replicates. Results. Inoculation at transplanting with R. irregulare (INCAM-11) remained effective during the three production cycles evaluated. The mycorrhizal inoculation of C. ensiformis not only increased the biomass and the quantity of recycled nutrients, but also resulted in the production of high quantities of mycorrhizal propagules in the soil. Implications. The feasibility of integrating the management of efficient arbuscular mycorrhizal fungi (AMF) strain, green manure and low rates of mineral-organic fertilizers to obtain high banana yields, an adequate plant nutritional status and a satisfactory mycorrhizal functioning was shown. Conclusion. The integration of efficient AMF strains and green manure increased the benefits of both practices and it is a promising way of managing the arbuscular mycorrhizal symbiosis in sustainable crop production.

Background. Mapping selective logging impacts on the Yucatan Peninsula is important to pursuing carbon emissions reduction and biodiversity conservation goals. Objective. To evaluate the effectiveness of applying remote sensing techniques using LANDSAT 8 OLI imagery to detect tropical forest disturbance from timber harvesting in four communally managed forests (ejidos). We further assess differences among them in terms of implementing improved forest management (IFM) and reduced impact logging (RIL). Methodology. Vegetation indices were calculated, and forest cover classification was performed to map logged and unlogged forest and specific harvest disturbances (e.g. felling gaps, skid trails, logging roads and log landings) in annual cutting areas of 2014. Accuracy assessments were conducted based on validation points collected in the field after logging. Results. We found that 75% of the binary classifications (logged and unlogged forest) had mean overall accuracies greater than 60%, representing a fair (40 to 70%) accuracy, although mapping of specific harvesting disturbances had poor accuracy (<40%). Vegetation indices that performed the best were normalized vegetation index (NDVI), Tasseled Cap Greenness and Tasseled Cap Wetness. Ejidos that applied IFM and RIL impacted a smaller percentage of their cutting areas and less area of forest per cubic meter of timber extracted, despite similar or higher logging intensities than ejidos without improved practices. Implication. Monitoring selective logging disturbance is important to improved forest management and certification of sustainability.  Conclusion. Mapping and monitoring impacts from selective logging by forest managers and technicians can be performed in a cost-efficient manner using LANDSAT 8 images, although accuracy could be improved with higher resolution imagery.
