Authors: DURMUŞ Aybüke , KORKMAZ Hünkar
Published: August 2023

Purpose: This study examines pre-service teachers’ perceptions and their professional preparation levels for multicultural education.

Design/Methodology/Approach: In accordance with the research problems, this study was conducted using a mixed method research and a partial mixed sequential and equal status design. In the quantitative part, 381 pre-service teachers were surveyed using the Multicultural Perception Scale (MPC) to assess their perspectives on multicultural education. In the qualitative part, 20 pre-service teachers were interviewed individually to determine their levels of professional preparation for multicultural education.

Findings: The quantitative findings of the study showed that pre-service teachers have a moderate level of perception their professional preparation levels for multicultural education. Pre-service teachers enrolled in the Primary Education program have a higher perception of multicultural education than pre-service teachers enrolled in other teacher education programs. Furthermore, there is no significant difference between grades. On the other hand, it appears that male pre-service teachers have significantly lower perceptions of multicultural education than female pre-service teachers. Pre-service teachers are observed to emphasize the terms "diversity, interaction, and togetherness" when defining multicultural education, according to the qualitative findings of this study. In addition, they emphasized the interactions between pre-service teachers and international students, the program's course content, and extracurricular activities in light of the findings regarding the teacher education program's contribution to and opportunities for enhancing the levels of professional preparation for multicultural education. Examining the recommendations of pre-service teachers for teacher education, it is evident that more opportunities for extracurricular activities, school experience, and observation are recommended. Another recommendation highlighted is the addition of a multicultural education course to the teacher education program.

Highlights: According to the findings, multicultural education must be more thoroughly integrated into teacher education programs. It is anticipated that the study's findings will contribute to future studies of curriculum development and research on multicultural education conducted by those involved in teacher education at the national and international levels.

Through her writings, she often depicts the brutal oppression of the tribal people by the money-lenders, upper class landlords, and government officials. As the crusader of the tribal people, Mahasweta Devi emphasizes on justice, mercy, equality, liberty, love and women empowerment. In this paper, the researcher has thrown light on how Devi warns the society of the dooming consequences of oppression as in the Book of Exodus.
Constructing Subaltern Worldview in Aravind Adiga’s The White Tiger
Authors: Kumar Praveen
Published: August 2023

The central concern for many Indian writers, settled abroad, either remains diasporic experiences or their concerns about the othering of the poor by the affluent in modern India against the backdrop of the realities of the two opposing conceptions of India: the envisioned Independent India of the post-freedom struggle and the modern India of the rich. Caste and class structures are an imperial barrier to democratic socialism and economic equality, which causes the poor to be victimized. Because they lack resources and are therefore helpless, the underprivileged continue to be used as tools of the elite capitalist class. With the background established, Adiga’s The White Tiger holds a central position to establish the voice of the marginalized to challenge the country's booming prosperity.

This paper attempts to critically analyze The White Tiger by Aravind Adiga through a socio-Political perspective to depict India’s socio-cultural and political context and how the larger politics impact the micro level realities of common people. Similarly, it attempts to establish a marginalized by showcasing the life of a low-born person involved in the local politics and policy.

Published: August 2023

Microplastics are one of the pollutants that threaten aquatic ecosystems and have become the focus of research in recent years by environmentalists worldwide. In addition to harmful base materials, microplastics have hydrophobic characteristics, so chemicals such as Persistent Organic Pollutants can stick to microplastics and cause chemical pollution in aquatics. Siombak Lake is located in the coastal area of Medan City, and it is predicted to be a microplastic distribution channel to the aquatics. This study aimed to analyze the abundance of microplastics in water, sediment, and fish in Siombak Lake. Sampling was conducted from November 2021 – January 2022 at Siombak Lake. Water samples to be analyzed were added with 90 g NaCl, then filtered and separated visually using a microscope. Microplastic in the sediment is separated by drying, volume reduction, density separation, filtration, and visual sorting. Fish samples were dissected, and then the digestive tract content of fish was diluted with 10 ml of saturated NaCl. The abundance of microplastics obtained in waters ranged from 93-519 particles/m3, and the Number of microplastics in sediment ranged from 521-1481 particles/kg dry sediment, while the abundance of microplastics in fish samples ranged from 0-6 particles/individual.Keywords: Microplastic, Abundance, Coastal, Pollutant, Siombak Lake

An experiment was conducted under the ICAR-All India Coordinated Research Project on Fruits to study the high-density planting (HDP) and nutrient requirement of banana at six research centres across the country, including Bhubaneswar (Orissa), Gandevi (Gujarat), Jalgaon (Maharashtra), Jorhat (Assam), Kannara (Kerala) and Mohanpur (West Bengal) to enable higher productivity of banana and profit to farmers. The objective of this study was to explore the possibility of increasing productivity through the intervention of only per unit plant population (through planting system) and level of nutrition, but without any interference to the regional choices of variety (eg., choice variety Nendran for Kerala or Martaman for West Bengal), production system (mono/poly- clone, single/multi-year plantation, and POP of respective states), for which national productivity ranges are much skewed also. Results indicated that intervention of only plant density could increase the productivity of banana within the existing system of production and choice of a variety of different regions or states. The experiment was laid out in RBD with four planting densities (S1P2, S1P3, S2P2 and S2P3, where S1=2m x 3m, S2=1.8m x 3.6m, P2=2 suckers/hill, P3=3 suckers/hill), three nutrition levels (F1, F2 and F3 , which is 100%, 75% and 50% of RDF) and one with region-specific conventional planting density and nutrition (100% of RDF) practices as control. The results of this experiment showed that HDP (S1P3, 5000 plants /ha) in banana, accommodating three suckers per hill at 2m x 3m spacing increased productivity over the conventional system at the Bhubaneswar, Gandevi, Jorhat, Kannara and Mohanpur centres. The increase in productivity due to HDP (5,000/ha) over control was 28.9% (RDF 25%) to 50.6% (RDF 100%) at Bhubaneswar, 15.2% (RDF 25%) to 21.9% (RDF 100%) at Gandevi, 4.0% (RDF 25%) to 7.4% (RDF 100%) at Jorhat, 33.5% (RDF 25%) to 43.5% (RDF 100%) at Kannara and 46.5% (RDF 25%) to 79.0% (RDF 100%) at Mohanpur centre. The nutrient requirement under HDP was 100% RDF at Kannara, 75% RDF at Bhubaneswar and Mohanpur and 50% RDF at Gandevi and Jorhat centres, which indicates a saving in cost of fertilizer input by 25% -50%. It is, therefore, recommended for HDP (5000 plants/ha) in banana, accommodating three suckers per hill at 2m x 3m (6.6 ft x 3.8 ft) spacing with 50% RDF in the agro-climatic regions of Gandevi and Jorhat, with 75% RDF in the agro-climatic regions of Bhubaneswar and Mohanpur and with 100% RDF in the agro-climatic region of Kannara in order to ensure higher productivity and profit to farmers.

Mango (Mangifera indica L.) is a salt sensitive crop and its cultivation in salt affected area is declining day by day. There is a need to find out the rootstocks to sustain under saline conditions which can be used for commercial cultivation of superior cultivars through grafting. To achieve this, the present study was carried out to understand the salt tolerance and sensitive nature of fifteen polyembryonic mango rootstock seedlings (EC-95862, Bappakkai, Vellaikolamban, Nekkare, Turpentine, Muvandan, Kurukkan, Kensington, Olour, Manipur, Deorakhio, Vattam, Mylepelian, Sabre and Kitchener) which were exposed to 0 mM, 25 mM, 50 mM and 100 mM concentration of NaCl+CaCl2 (1:1) salt. The outcome of this study revealed that there was reduction in K+, Ca++, Mg++, Fe++ and Zn++ while the content of Cu++ and Mn++ in both leaf and root tissues were found to increase with gradual increase in salt concentration from 0 to 100 mM. The overall results of this study revealed that the salinity stress caused the alterations in mineral nutrient composition of polyembryonic mango genotypes. Among the fifteen genotypes the seedlings of Turpentine, Deorakhio, Olour and Bappakkai respond better in maintaining the mineral nutrient status in leaf and root tissues under higher level of salinity.
Characterization, inheritance of male sterility and development of male sterile and maintainer lines in ridge gourd (Luffa acutangula (Roxb.) L.)
Authors: B Varalakshmi , P.E. Rajasekharan
Published: August 2023

Two male sterile mutants IIHRRG-12MS (long fruited) and IIHRRG-28MS (medium long fruited) were identified from the ridge gourd germplasm IIHR-12 and IIHR-28 respectively at ICAR-IIHR, Bengaluru. These two male-sterile (ms) sources were characterized by the production of rudimentary male flowers in the racemes in contrast to the bright yellow flowers with fertile pollen and healthy anthers in male fertile, monoecious plants. Using these ms lines the inheritance of male sterility was worked out, which is cytoplasmic genic male sterility (CGMS) type, with single dominant gene either in homozygous or heterozygous condition restoring male fertility in the presence of sterile cytoplasm. In order to develop F1 hybrids using male sterility, several male sterile and maintainer lines were developed in different genetic back grounds such as green/dark green fruit colour and short/medium long/long fruit length.

Resistance responses in the leaves of eight rose genotypes, Knock Out (highly resistant), Arka Nishkant (moderately resistant), R. multiflora (highly susceptible), Arka Swadesh (highly susceptible), IIHRR 13-4 (susceptible), Arka Parimala (susceptible), R. indica (susceptible) and IIHRR 4-15-12 (moderately susceptible), exhibiting varied levels of resistance against black spot were investigated post artificial inoculation with black spot pathogen, Diplocarpon rosae. There was consistent increase in the activities of defense related enzymes such as catalase, peroxidase, polyphenol oxidase, superoxide dismutase and phenylalanine ammonia lyase and other defense related secondary metabolites like phenols and flavonoids at different phases of black spot progression and increase was high in resistant genotypes Knock Out and Arka Nishkant. The peak activity of defense enzymes and high concentration of other metabolites was witnessed during early stages of infection in the resistant genotypes while it was during later phase in the susceptible genotypes. These results suggested that the faster and stronger activation of defense system is associated with the resistance against black spotin the rose genotypes.

Published: August 2023

Dry chilli production in India condition faces many challenges apart from adverse weather conditions, labor-intensive production practices and higher overall production costs are limiting profitable dry chilli cultivation. Therefore, a study was carried to know the key constraints in current chilli production practices in eight major production districts of three states. A systematic research and development approach is essential to know the range of constraints and farmers preferences over technological options for field operations. The harvesting operation alone demands 43% of labour 360.5 man-days/ha. So, red chilli harvesting mechanization is a definite immediate requirement to reduce labour input. Farmers (47%) prefer small size self-propelled chilli harvester over tractor operated equipment. In the production catchments, farmer also inferred to change the cultivation practices to mechanize chilli production operations, but 18% of farmers hesitant to adopt one-timeharvesting chilli varieties due to suspicion about the yield potentials.

Published: August 2023

Understanding gene action of different traits is of utmost importance for formulating successful breeding programs. The population was developed involving Arka Neelachal Shyama and CARI-1 to inquire the gene actions controlling the inheritance of several growth as well as yield attributingparameters through six-generation mean analysis. Three parameter model revealed the insufficiency of the simpler additive dominance model for the evaluated traits, referring to the existence of inter-allelic interactions. Six parameter model was implemented to better understand gene actions. Most of the yield and attributing traits under study except number of branches showed a high estimate of dominance as well as environmental variance, disclosing a lower extent of heritability. The number of branches was observed to be controlled by duplicate epistasis. Hence, for the fixation of this trait, the best strategy is to exercise minimal selection during advance generations, followed by intense selection during later generations (F4- population onwards). The preponderance of the narrow sense type of heritability revealed that dominant effects were predominantly accountable for the existing genetic variation. Hence, recurrent selection followed by bi-parental mating and selection during the later stage of generations is advised to increase the occurrence of favorable alleles and accumulation of desirable genes.

Physico-chemical and enzymatic changes in mango (Mangifera indica) cv. Dashehari inresponse to postharvest application of chitosan (0, 0.5 and 1.0%) were studied during 4 weeks that were stored between 10±1 °C, 90-95 % RH. Fruits were evaluated for various quality parameters such as firmness, weight loss, pulp colour, β-carotene, soluble solid content (SSC), titratable acidity (TA) and activities of polygalactouronase (PG) and cellulase on 0, 7, 14, 21 and 28 days. Results exhibited that chitosan coatings (1.0 %) effectively reduced the weight loss (5.82 %) and markedly slowed down the ripening changes as evidenced from their retention of fruit firmness (15.50 N), maintenance of SSC (18.85 %) and TA (0.44 %) at 21 days of storage. Chitosan coatings also retarded the pulp colour development and lowered activities of PG and cellulase enzymes as compared to non-coated fruits. Overall, chitosan coating at 1.0% was found to be most effective in enhancing the storability and quality of mango fruits at cool storage temperatures.

Application of 0.8 % FeSO4 recorded maximum number of branches (26.75), plant height (29.73 cm), plant spread (45.17 cm), number of leaves (22.63) and seed test weight (15.63 g) and number of flowers per plant (134.04). However, application of 0.2% macro FeSO4 resulted in early bud appearance (50.50 days) and higher flower diameter (8.09 cm). ‘Fiesta Gitana Mix’ outperformed over ‘Fiesta Yellow’ for most of the vegetative and floral characters. The ‘Fiesta Yellow’ variety with oil content (13.97%) had an edge over ‘Fiesta Gitana Mix’.

Annona cultivar ‘Arka Sahan’, an inter-specific hybrid of Annona atemoya × A. squamosacomes to harvest during August-September under mild tropical climate, which coincides with monsoon rains resulting in poor fruit quality and high susceptibility to anthracnose and fruit fly. An attempt was made to advance the fruiting in this hybrid through pruning during 2016- 17 and 2017-18. The effect of three pruning levels (25, 50 and 75% of previous season’s growth) at five different times (60, 75, 90, 105 and 120 days after final harvest of previous crop) on flowering and fruiting were compared. Early sprouting, flowering and fruit harvest were recorded in trees pruned to 75% of the past season’s growth in both the years. Earliest fruits were harvested 271 (3rd week of June) and 268 (2nd week of June) days after pruning in trees pruned during first week of October in 2016-17 and 2017-18 respectively (P<0.05).Bigger fruits with lesser seeds per 100 g of pulp (P<0.05) were harvested from trees pruned to 75% and 25% levels in the first and second year, respectively, irrespective of pruning time. Tree canopy following pruning at 75%level recorded higher light interception and photosynthetic rate (P<0.05). Pruning time and levels significantly influenced the biochemical constituents of leaf and shoot. The fruiting in cultivar ‘Arka Sahan’ could be thus advanced by 8-9 weeks to June from the normal season of August-September with comparable or better fruit quality by pruning 75% of the last season’s growth during October.

Availability of dwarfing rootstocks is an important pre-requisite for improving productivity of mango orchards in India as it facilitates high density planting as well as impart uniformity within an orchard. An attempt was made to induce variability in polyembryonic mango genotype Nekkare for dwarfness by treating kernels with different doses of gamma radiation ranging from 15 to 35 Gy. Irradiation created significant variation in plant height, stem girth, number of nodes, inter-nodal length, number of leaves, leaf blade length and leaf blade width. The highest reduction in seedling height along with highest variation was observed at 35 Gy where the seedling height ranged from 11.50 to 33 cm with a mean of 23.12 cm as compared to mean plant height of 44.55 cm in control ranging from 33.50 to 56 cm. Further, the effect of irradiation on stomatal parameters was also investigated and the highest stomatal length and width was recorded at 15 Gy (63.39 μm) and 20 Gy (63.12 μm) respectively while 30 Gy treatment produced maximum stomatal density (13.85 per μm2). Furthermore, theconcentration of ABA was found to be highest (429.1 ng/gm) in morphologically dwarf (putative mutant) progenies of Nekkare. The results suggest effectiveness of induced mutation for developing dwarfing rootstocks in mango to be used in high density planting.
Growth trend and potential of horticulture in Northeast India
Authors: Das Gupta Madhuchhanda
Published: August 2023

The Northeast region of India is endowed with diverse soil and agro-climatic conditions that are conducive to the growth of a large variety of temperate and tropical horticultural crops. Fruits, vegetables, and spices of the region are highly nutritious and have a market within and outside the country. The paper is an attempt to assess the potential of horticulture in the region. To gauge the state-wise and regional growth trend and variability in area and production of these crops during the period 2009-2019, Compound Annual Growth rates and Instability Index have been computed from secondary data. The study reveals a rising regional growth trend with low instability for the production of fruits and vegetables and moderate instability for spices. This indicates the possibility of sustainable development of horticulture in all the Northeast states through strategic planning. Fruits and spices of the region also have a market in Middle-East and neighbouring countries. However, lack of commercialisation, poor market intelligence, and linkages are impeding the growth of exports. To unleash the true potential of horticulture, it is imperative to develop infrastructure, modernise farming and establish seamless value chains with greater market integration.

Published: August 2023

Chrysomelidae (hereinafter – leaf beetles) forms one of the largest families of trophically specialised phytophagous beetles. Therefore, a detailed study of leaf beetles is an important component of research aiming to assess the diversity and specificity of biota in Protected Areas. Based on the results of original studies (2011, 2013, 2014, 2021) and a critical review of the literature, this paper presents the species composition and analyses the fauna of leaf beetles in the Zhiguli State Nature Reserve, Russia. It was found that the studied fauna belongs to the richest local faunas of leaf beetles in the Middle Volga Region, and it has a considerable originality. In total, 230 leaf beetle species have been recorded in the study aera. Of them, 47 species were recorded for the first time in the Zhiguli State Nature Reserve, including 23 species recorded for the first time for the fauna of the Samara Region. The leaf beetle fauna is characterised by a complex composition, including species of European, Siberian and Kazakh-Turanian faunas, and it includes a relict endemic of Eastern Europe, Chrysolina roddi. An analysis of the biotopic distribution of leaf beetles showed that the highest number of species (116) is represented in the forb and petrophytic steppes of the Zhiguli Mountains. It also includes quite rich complexes of semi-aquatic and meadow biotopes of the floodplain and islands of the River Volga (98 species), as well as upland forest (93 species) (including broad-leaved forests and pine forests). In the Zhiguli State Nature Reserve, trophically specialised leaf beetle species are associated with plants from 38 families. Their most numerous groups are related with Asteraceae (28 species), Salicaceae (23 species), Brassicaceae (17 species), and Lamiaceae (15 species). The leaf beetle fauna of the Zhiguli State Nature Reserve can be considered one of a reference group in the forest-steppe of the Volga Upland. This confirms its great importance for the preservation of the original natural ecosystems in the Middle Volga Region.
HOTEL COMPANIES AT BUCHAREST STOCK EXCHANGE. WHAT DO THEY OFFER TO INVESTORS?
Authors: POP Cornelia
Published: August 2023

Hotel groups listed on various security exchanges have the tendency to be representative for their respective country and/or to be emblematic worldwide. They expand and evolved from an owner-operator business model, still dominant in the 1980s, toward a sophisticated combination of the owner-operator model and asset-light business model. In the case of Romania, the owner-operator business model is dominant and is the common ground for the hotel companies listed at Bucharest Stock Exchange. The present paper has the following objectives: a) to investigate which of the former hotel companies listed on Rasdaq were chosen to be transferred on the new alternative trading system; b) if new hotel companies were willing to become publicly traded on BVB or in AeRO; c) to identify the portfolio of hotels for the listed companies, and d) to investigated the trading frequency, volume and value, and extract potential patterns. The period under scrutiny is May 2015 – May 2023. Based on the findings of the present paper the Romanian listed hotel companies do not attract the investors’ attention since they do not offer too much. Some of the problems might be generated by the low free-float and controlling shareholders/groups. Though, the main problems seem to be related to the companies’ lack of proper transparency regarding their activities (and profit centers), hotel/lodging portfolios, and the absence of (at least) domestic known brand.

“Quien quisiere ser sabio hordene su coraçon segund el tiempo”. Séneca en la literatura medieval de sentencias
Authors: Esther Ramadori Alicia
Published: August 2023

La presencia de Séneca resulta especialmente funcional para la composición de compilaciones sapienciales de sentencias en la Edad Media castellana: Flores de filosofía, Vida y costumbres de los viejos filósofos y Floresta de philosophos. En algunas de estas sentencias atribuidas al filósofo latino pueden encontrarse varias representaciones del tiempo (asimilado a la noción de época o edad). El análisis recorre Flores de filosofía (compilación del siglo XIII que asocia los conceptos de tiempo y reinado) y, después, Vida y costumbres de los viejos filósofos (colección de biografías que pretende crear una historia de la intelectualidad). Finalmente, se expone la representación del tiempo en las sentencias senequistas de Floresta, obra sustentada en la ideología nobiliaria, de acuerdo a los paradigmas humanistas emergentes, que también continúa la tradición sapiencial medieval.
