The Nanotechnology industry is growing rapidly, leading to concerns about the potential ecological consequences of the release of nonmaterial to the environment. Titanium dioxide nanoparticles (TiO2 NPs) are widely used in commercial products such as sunscreens and toothpastes, industrial products like paints, lacquers and paper, and in photocatalytic processes such as water treatment. Also, TiO2 NPs are indirectly discharged in agricultural soils through irrigation or sewage-sludge application and directly as nanofertilizers or nanopesticides. Soil microorganisms are key contributors to nutrient cycling and are essential for the maintenance of healthy soils and sustainable agriculture. Although the antimicrobial effects of a broad range of nanoparticulate substances have been characterised in vitro, little is known about the impact of these compounds on microbial communities in environments such as soil. This study focused on the acute effects of TiO2 NPs on soil microbial communities such as bacteria, Fungi and Actinomycetes. This research revealed substantial shifts in bacterial, fungal and actinomycetes community composition in soils amended with TiO2. The TiO2 NPs exerted an adverse effect on the microbial population, causing the reduction of bacteria, Fungi and Actinomycetes in the substrate. The viability of the microbial population was reduced at the high concentration (50 mg kg−1) of TiO2. Results demonstrate that microbial communities differed in their sensitivity to TiO2 NPs with its various concentration and the release of TiO2 NPs to the environment has the potential to alter the composition of these microbial communities, which could have implications for the stability and function of soil ecosystems

Involving Disadvantaged People in Dialogue: Arguments and Examples from Mental Health Care
Authors: Rudnick Abraham , Subramanian Priya , Meredith Hazel , Cizman Juna Lea
Published: August 2022

This paper examines the theoretical and practical basis for engaging in dialogue with very disadvantaged people. Using a selective literature review, conceptual analysis, and clinical examples, we explore the reasonable limits of dialogue with disadvantaged populations in order to better understand dialogue, as well as to explore ways to effectively involve disadvantaged people in dialogue. Although people with serious mental illness represent only one very disadvantaged population, we suggest that examining dialogue with this population can serve as a test case for dialogue with disadvantaged people more generally. A recovery-oriented approach can support dialogue processes with people who have mental illness, as their recovery may require, or at least benefit from, dialogue. The inclusion of two clinical scenarios serves to highlight differences in clinical and personal recovery outcomes when dialogue is and is not present in mental health care. Furthermore, although it is not required from a standard principles-based bioethical approach, involving people with mental health issues in dialogue can complement a standard bioethics approach, through dialogical bioethics. A dialogical approach goes beyond the standard principles of bioethics by means of a process that allows relevant bioethical principles to be prioritised, based in part on the person’s informed choice. Overall, our findings suggest that involving very disadvantaged people in dialogue – in this case, people with serious mental illness – is not only possible, it is plausible and can be constructive in relation to a variety of dialogical aims that range from informing to supporting to decision-making processes.
Martin Buber, I-It, and Utopias: Economics and Dialogue in the Age of Neoliberal Globalisation
Authors: Tinker Andrew
Published: August 2022

The turn to populism in Western governments is increasingly marked by a breakdown in communication between those who disagree. Martin Buber’s analysis of I-It as the nature of communication accounts for the impersonality and incivility of populist responses to globalisation. His writings on utopias account for the lack of centre in societies formed solely around bureaucratic means of production. This article elaborates upon his concept of I-It from I and Thou and his account of the breakdown of Marxism. These point to a loss of Thou as a binding and guiding force in community, leading to the uncivil distrust and populist reactions to globalisation. Neoliberal globalisation, as with the I-It interaction, is marked by a disconnection from nature in a system that is centred around self-interest. Buber theorised his Thou as the place where humanity is reconnected with nature and joined to others in dialogue. His work points to religious community as one witness to communities where forms of dialogue and interaction lie beyond market-based solution creation and negotiation. In Buber’s work, a diagnosis for the anger and mistrust between neighbours and citizens in the present moment becomes salient: a disconnection from Thou as the organizing centre of community.
‘Just Send Me Word’: the Promise of Dialogue
Authors: Davey Nicholas
Published: August 2022

This paper specifically concerns an aspect of the central place given to dialogue in Gadamer’s philosophical hermeneutics. Though understanding is presented as the unquestioned achievement of dialogue, there is scant attention to a prior question: ‘What draws us into dialogue in the first place?’ Gadamer’s treatment of dialogical understanding as an event tends to obscure the necessary pre-conditions of its emergence. He correctly assumes that texts, artworks, literature speaks directly to us, even disarm us by their address. Yet, what disposes us to listen? Even if we hear nothing in a dialogical claim, what impels us to listen again or more closely to what might be being said? The paper attempts to answer this question and throw light on this, an obscurer aspect of Gadamer’s thinking. We will argue in the vein of philosophical hermeneutics and seek an answer to the question its approach to dialogical understanding supposes but seems neither to ask nor answer. Our central argument is that within the perspective of philosophical hermeneutics, the importance of dialogical exchange lies not in what is transmitted between interlocutors but in the respective hermeneutic effects of that exchange. In dialogue there is no literal ex-change of ‘hermeneutic content’ between one speaker and another. We shall argue that it is not what is literally exchanged that matters but, rather, what participation in that exchange can unexpectedly bring about within the understanding of each speaker and often contrary to their willing and doing.
How Does the Act of ‘Speaking in Tongues’ Contribute to a Theology of Place?
Authors: Evangelou Preston

Building Capacity for Dialogue Facilitation in Public Engagement Around Research
Authors: Escobar Oliver , Faulkner Wendy , Rea Heather J
Published: August 2022

This paper shares our experiences and reflections on a training programme which seeks to build capacity, across the public research sector in Scotland, for developing and facilitating dialogic approaches to public engagement. We came to an interest in dialogue and deliberation by different routes, but got the opportunity to collaborate on this thanks to institutional funding for culture change around public engagement in the sector. The analytical framework from which we developed the training focuses especially on the micro-politics of communication patterns in deliberative and dialogic engagement processes. The training programme thus sought both to raise awareness of the principles and practices of dialogue, and to build skills in the demanding craft of facilitation. Our training approach has two key features: it integrates theory and practice; and it endeavours to make the general themes of dialogue and deliberation relevant to the specific context of public engagement activities in universities and research institutes. Feedback from participants over four years indicates that this approach is working: awareness and skills are growing in quite concrete ways. In addition, there are encouraging signs of shifts and reflection over the ‘expert culture’ in this community of practice.
Geochemistry of Volcano-sedimentary and Plutonic Formations of the Agbaou Gold Deposit, Ivory Coast
Authors: Nestor Houssou N’Guessan , Herve Kouadio Fossou Jean Luc , Ephrem Allialy Marc , Roland Kouassi Brice , Koffi Adingra Martial Pohn
Published: August 2022

Located in the south-west part of the Fettekro greenstone belt, Agbaou gold deposit is marked by three major lithological units: (i) a volcano-plutonic unit composed of basaltic to andesitic lavas, amphibolites, chlorite-schists and sills of microdiorite and microgabbro; (ii) a volcano-sedimentary unit containing pyroclastic lavas (basaltic and dacitic) and sediments (shale and grauwacke); (iii) the late felsic dikes (rhyolite and rhyodacite) probably contemporary with the formation of granitoids form the third unit. These host rocks are mostly intensely deformed and altered. Alteration phenomena were revealed by the high values in fire loss, the decreasing of silica contents, the sometimes high values of alkaline for rocks also basic, the constant depletion in LREE and LILE. The Eu and Nb negative anomalies reveal a crustal contamination of magmatic series. Basaltic lavas are volcanic arc tholeiites nearing N-MORB type; they are associated to a magmatogenesis of ocean floor. Their magmatic source would probably be spinel lherzolitic type. Andesites have a calc-alkaline composition and seem far link to active subduction margin. Geodynamics context would be that of an area where transcurrent faults of lithospheric extension generate heat corridors able of generating by fusion the andesitic calc-alkaline magma. This context would probably be the one that prevailed during the establishment of the gold mineralization. Pyroclastic rocks of dacitic composition as acid lavas (rhyolite and rhyodacite) have also evolved in this same geotectonic context. Plutonic rocks are located in arc-volcanic granites field, while metasediment are linked to active continental margin field.
I Want but I Can’t: The Dilemma of EFL Learners in Practising English in the Saudi Context
Authors: Alnasser Suliman M. N.
Published: August 2022

The current literature suggests that learners in foreign English language learning contexts may suffer from the lack of opportunities to practise English. Language practice is regarded as fundamental for mastery of English. This study aimed to investigate Saudi EFL learners’ English language use outside the domain of the classroom. A mixed-method approach was adopted for data collection by employing an online survey with an open-ended section and conducting semi-structured interviews. The study participants were male and female students undertaking BA English programs at Saudi universities across the main five regions in the country. The study adopted a convenience sampling technique, and a total of 627 students responded to the survey (M = 291; F = 336), and eight students were interviewed (M = 5; F = 3). The data collection process went through two phases to obtain deeper insights into the investigated phenomenon: first, administering the online survey and conducting the analysis to extract the main themes of inquiry; and second, using these themes as a guide for conducting the interviews. The study’s main findings include learners finding themselves in a dilemma where they desire more practice of English outside the domain of the classroom and, at the same time, lack proper opportunities for practice. Implications of the study are also discussed.
A Battle Against One’s Soul: An Analysis of Lady Macbeth’s Functions as the Other Self to Macbeth
Authors: Huang Min
Published: August 2022

The play Macbeth is one of William Shakespeare’s most well-known tragedies. This research is intended to analyze the functions of Lady Macbeth as the other self to Macbeth. She is not only the motivator of Macbeth’s self-assertion, but also the silent bearer of Macbeth’s burden of conscience and the reflector of Macbeth’s self-alienation. Undoubtedly, Lady Macbeth plays a crucial role in the tragic end of Macbeth since it’s she that improvises Macbeth to commit crime. Her incitements and actions, nevertheless, are only the overt show of Macbeth’s inward eagerness to assert himself as a brave man. Lady Macbeth, furthermore, conscientiously suffers the burden of Macbeth’s sense of guilt later on. And her alienation from Macbeth indicates the latter’s self-alienation, who has gone the wrong direction but can no longer find the way back. Their relationship shows the process of Macbeth’s self-definition and vividly depicts the ambivalence of Macbeth’s tortured self.

Authors: Bushra M.T.F. , Nafees S.M.M. , Abdullah M.M.A. , Mazahir S.M.M.
Published: August 2022

Waqf is an essential component of the Islamic economic instrument that is firmly considered to be capable of resolving socio-economic issues, primarily in the effort to eradicate poverty caused by a lack of income and work. Based on the analysis of the semi-structured interview, this study seeks to investigate the role of the Waqf Board of Sri Lanka and the challenges and issues arising in managing waqf assets. The review of the literature contributed to constructing its theoretical structure. The findings reveal several shortcomings in the administration of waqf assets, including insufficient skilled human resources, lack of utilization of waqf assets, unawareness of the community on waqf, misuse of the waqf assets, and shortage of transparency and accountability. Hence, the study proposes that the proper management of the waqf assets would be sufficient to meet most if not all the needs of the community to a significant extent. The findings will be beneficial to waqf managers and will help enhance waqf institution administration and management. The findings will be beneficial to waqf managers and will help enhance waqf management.

Language is the medium which is used to express the ideas and thoughts of human beings. English is an international language that coordinates with all the sectors in Sri Lanka. Especially in the Educational sector. In the state universities of Sri Lanka, English language courses are being integrated as a common subject in most courses. Hence, the study aimed to identify the challenges faced by undergraduates in enhancing their English language skills. Based on Mixed methods, the primary data was collected through a closed-questionnaire distributed among 100 students out of 350 second-year undergraduates of the Faculty of Islamic Studies and Arabic Language of South Eastern University of Sri Lanka and semi-structured interviews of 30 of them. Secondary data contributed to constructing its theoretical structure. The major findings reveal the emergence of several issues regarding the speaking and listening skills due to the dominance of their mother tongue, Tamil language, other than writing and reading skills because of their involvement in improving such skills through various strategies.
FORMATION OF STUDENTS' COMMUNICATIVE COMPETENCE WITH THE HELP OF NONFICTION TEXTS
Authors: Nadolskaya Yulia , Epifantseva Larisa , Khomchak Olena , Volkova Irina , Barantsova Irina
Published: August 2022

The importance of forming communicative competence through the lens of nonfiction texts is considered in the article. Several directions are offered - exercises on forming the culture of publicistic speech of students in the process of learning German, and the effectiveness of using the basic communicative method of teaching a foreign language in higher pedagogical education. Communication is defined as communication, combination, transmission, and perception of information in interpersonal relationships that implies a communication process. The norm of communication depends on adherence to certain moral qualities and the culture of speech of the interlocutors, in our case students. Today, as ever, foreign language is becoming an effective factor in the socio-economic, scientific, technical, and cultural progress of society.

In the article, nonfiction texts are also considered as one of the factors in the formation of nonfiction speech in student youth. The culture of nonfiction, after all, is the meaning of language and its use in the whole set of functional styles inherent in it. After all, according to the authors, the texts of newspaper and journalistic journalism most strongly encourage students to exchange ideas and opportunities for creative self-realization, formation of critical thinking, associative thinking, and spontaneous foreign language.
INTERCULTURAL DIALOGUE AS THE BASIS OF EDUCATIONAL SPACE
Authors: Garmash Olena , Barantsova Irina , Rutkovsky Maxim
Published: August 2022

The article is based on the idea that all the various external manifestations of the spiritual essence of a person are complicated by the lack of development of target objects, principles, and potential of cultural-educational and pedagogical means of harmonizing the interaction of people. The first place in it is asserting the dialogic style of life of the subjects involved in the cultural and educational space. The analysis of intercultural education as a social institution and sociocultural space for an individual’s socialization has made it possible to suggest that it has the potential to ensure the spiritual security of Ukrainian society, particularly regarding intercultural relations. The authors conclude that dialogue cooperation, as a certain humanitarian technology, should direct all educational discourses into the development of a dialogue of cultures and its orientation towards philosophical reflection in the educational process. Philosophical reflection approximates the notion of “intercultural dialogue” and other terms and even categories that function in scientific and academic life. The article stresses that communication space is often contradictory to determine at least the meaning of these concepts and release them from stereotyped connotations, falsifications and quasi-intellectual layers.

PT Ikafood Putramas hopes to carry out its activities on a set schedule in order to optimally meet its productivity. In this context, how employees can perform at their best and provide incentives to motivate employees to get the job done. In this context, the aim of this study is to show how important the influence of material and immaterial incentives is on employee performance. This type of survey uses questionnaires as a data collection tool that are distributed among respondents with a sample of 54 people. The data analysis used a descriptive analysis that included the distribution of the elements in each variable and then a simple linear regression analysis. The results of the linear regression test and partial regression analysis showed that the motivation of the simultaneous variable (X) on employee performance (Y) with the value R-squared was 0.129. This figure shows that the simultaneous incentive variable (X) used in this regression equation contributes 12.9% to employee performance (Y), while the remaining 87.1% is examined under the influence of other variables outside the two independent variables. Proposals for PT Ikafood Putramas are consistent with research and discussions about employee incentives, and it is recommended that companies pay more attention to incentives that influence business performance.

Authors:   Nepal Agricultural Research Council, Ghimire R. P. , Adhikari D. P. , Adhikari D. , Ghimire S. H. , Amgain R.
Published: August 2022

Productivity of crossbred dairy cattle in the milk production pockets of Nepali hills are considerably low due to their severe undernourishment in the paddy straw-based feeding regimes. An experiment was carried out at on-farm of Tanahun district in order to compare popular fodders (Ficus semicordata cv. Montana S.M. Amatya and Pennisetum purpureum K. Schumach. cv Mott) with and without nutrient supplementation via the urea-molasses-mineral block (UMMB) for milk yield, milk fat content and lactometer reading. The experiment was conducted in a 2×2 factorial arrangement of Completely Randomized Design (CRD) with 10 replications. The milking cattle of Jersey crossbred from third to fifth parities with similar milk yields and stages of lactation were taken as the experimental animals. The results of the study showed that Rai khanayo (F. semicordata) fodder performed better (p<0.01) than Napier (P. purpureum) for milk yield, milk fat content, and lactometer reading. Likely, significantly enhanced (p<0.05) milk yield with better fat content and lactometer reading were obtained for the UMMB supplemented group. Feeding 10 kg of F. semicordata fodder with 300 g of UMMB supplementation, 10 kg of rice straw and 2 kg of wheat bran as the daily ration improved the milk yield, milk fat content, and lactometer reading considerably (p<0.05) than other treatment combinations in the farmers’ field. These simple and practical technologies can rigorously be used for the substantial improvement of the milk yield and its constituents of crossbred dairy cattle, and also for their health in the hills of Nepal.
Pathogenesis-related proteins of tea triggered by Exobasidium vexans
Authors: Chakraborty B N , Sharma M , Das Biswas R , Ghosh A N
Published: August 2022

The defense strategy of tea plants against Exobasidium vexans are multifold and include accumulation of pathogenesis-related (PR) proteins. A study on the association of defense enzymes with resistance in tea plants triggered by E. vexans revealed significant changes in the level of β-1.3-glucanase (PR 2) and chitinase (PR 3) exhibiting antimicrobial activity. Accumulation of defense proteins differed in time and magnitude. Time course studies points towards accumulation of PR-2 and PR-3 in the early hours, PR-9 later on and finally the antifungal metabolites that confer resistance to the plants. Treatment with salicylic acid (SA) stimulates a multicomponent defense response in tea leaves which was confirmed by immuno-localization of PR 2 and PR 3 in tea leaf tissues following induction of resistance. Induction of PR-3 in suspension-cultured tea cells following SA treatment was confirmed immunologically using antibody probes (PAb-chitnase). Subcellular localization of PR-3 and PR-2 in tea leaves were also confirmed by indirect immunogold labeling. Marked increase in frequency of gold particles following elicitation by SA treatment was evident. Cell defense responses associated with systemic acquired resistance induced by SA against E.vexans has been discussed in relation to the possible role of PR-proteins in immunizing tea plants.

Plant viruses cause severe diseases leading to enormous crop loss. The present day viral researches of economic plants are centered on identification of virus, molecular characterization and management of viral discases. Till date more than thousand viruses have been classified into several families. It is desirable to know about the different virus families along with their type genus and/or important genus. But due to an enormous volume of literature published on this aspect, it becomes difficult to study all of them. Hence the present review has highlighted the salient features of the major plant viruses which have been classified at the family level. Most of the virus families have been discussed with important/type genus of each family. Some viruses which could not be placed in any family have been grouped as 'no family". Importance of molecular data, immunological data and data on protein configuration of coat proteins along with bioinformatics and its predictive power have been highlighted.
Regulation of trehalose metabolism by protein methylation in a mutant strain of Saccharomyces cerevisiae
Authors: Basistha Bipasha , Ghosh Anil Kumar , Ghosh Sumita
Published: August 2022

Trechaloseis a non reducing disaccharide occurring in a wide range of organisms, from bacteria, yeast, to lower and higher plants and insects. It is economically important as a potent stress protectant, protein and biological membrane stabilizer: hence biosynthesis of trchalose is an extremely important event. Regulation of trehalose metabolism by protein methylation has been reported from previous works of this laboratory. Trehalose metabolism was monitored during different stages of growth of Saccharomyces cerevisiae. HPLC and enzymatic determination of trehalose. glucose, trehalose 6 phosphate phosphatase TPP) and trehalose 6 phosphate synthase (TPS) were carried out. It was noticed that trchalose, glucose TPP and TPS pcaked at Aso20 during growth but during this period the hydrolyzing enzymes, acid trehalase (AT) and neutral trehalase (NT) are found to be low. Effect of a potent universal methyl group donor S-adenosyl-L-methionine (AdoMet), and a methylation inhibitor, oxidized adenosine (Adox) on trehalose metabolism has been studied. Trehalose metabolism is altered when YPD grown cells were incubated for I hr in presence of cither 1 mM Adox or AdoMet at 30'C and pH 6.0 TPS showed a slight increase in specific activity in cells incubated with AdoMet over Adox. Trehalose level of Adox treated cells were seen to be lower than control throughout the period of incubation. Trehalose level initially decreased upto 4 hours in all the sets by utilizing pre-synthesized trehalose, thereafter the AdoMet incubated cells showed sharp increase in trehalose content, in 8 hours 3 fold, in 24 hours nearly 5 fold with respect to others. At the point of 48 hours, cells reached stationary phase in all sets and trehalose level was found to increase.

Published: August 2022

To find out a potent phosphate solubilizing strain of diazotrophs, fifteen Azotobacter strains were isolated from local sources. They have been tested for the ability to solubilize rock phosphate in vitro and production of acid in the medium. Almost all the strains solubilized rock phosphate which ranged up to 45.5%. Azotobacter sp. R12 was found to be a potent one, which solubilized 30 to 46% phosphate from different rock phosphates. Almost maximum solubilization of P and acid production was achieved at four days of growth of the organism. The strain produced ascorbic acid in the culture medium, the primary cause of rock phosphate solubilization. Addition of (NH4)2S04 in the culture medium reduced the solubilization of phosphate with increasing concentration beyond 0.25 mg/ml for Jordon rock phosphate. Increasing concentration of CaCl2 and CaCO3 also reduced the P solubilization from Jordon rock phosphate by the strain. Kinetics of solubilization and acid production showed a linear relationship till the 5th day of incubation, then P level becomes static. Adding EDTA at 5 mg/ml as chelating agent of calcium ions to 5 days old culture increased the P solubilization to 81%. Increasing EDTA concentration in 3 days old culture showed linear relationship between concentration of EDTA and P solubilization.

The challenge facing Indonesia today is child labor in the agricultural sector. Agricultural land which is the center of livelihood for most of Indonesia's population makes children as workers in the agricultural sector. Based on data on the assessment of child labor in Indonesia in the agricultural sector and recommendations by Modelez International in 2020, there are more than 4 million child workers in Indonesia and 20.7 percent of them are trapped in hazardous work environments or the Worst Forms of Child Labor (WFCL). Strategies to reduce the number of child labourers. among others, ensuring that the issue of child labor remains in the policies and programs of special child protection in the district or city. Development of a women-friendly and child-friendly village model as an approach to child labor prevention and coordination of child labor prevention in 4 priority sectors, namely agriculture, fisheries, services, and tourism. The purpose of this paper is to find out the legal protection of child labor in the agricultural sector, especially in Indonesia and to explain the realization of the women-friendly and child-friendly village model. The result of this paper is the realization of a women-friendly and child-friendly village model that can be used as a model for other villages in Jember district. The recommendation to be achieved is the existence of a village pilot area that is friendly to women and cares about children which can be directly fostered by the relevant agencies.

This paper is devoted to study a quasistatic contact problem be-tween a viscoelastic material with long memory and a foundation. Thecontact is modelled with a version of Coulomb’s law of dry friction anda general normal compliance condition. We derive a variational formu-lation of the model and, under a smallness assumption, we establishthe existence of a weak solution to the problem. The proof is based onthe time-discretization method, the Banach ﬁxed point theorem andarguments of compactness, lower semicontinuity and monotonicity

AN ITERATIVE METHOD FOR DIAGONALIZATION OF THE FROBENIUS COMPANION MATRIX
Authors:   Faculty of Mathematics and Informatics, Shumen University, Nedzhibov Gyurhan H.
Published: August 2022

In this work, we develop a new and eﬃcient iterative method for di-agonalization of the Frobenius companion matrix. The method can beused for approximating all of the eigenvalues and corresponding eigen-vectors. It can also be used for simultaneous inclusion of all simplezeros of the corresponding characteristic polynomial. Local conver-gence analysis of the method is included. We prove that it is locallyquadratically convergent. Some numerical examples demonstrating ef-fectiveness of the proposed iterative method are also included

This is a qualitative study which explores different factors affecting the career decision-making of Grade 10 students leading to a choice of becoming a teacher. A total of 388 students participated in the study with 40 students from Metro Manila who conveyed they are pursuing teaching as a career. Data analysis involved coding and categorizing of responses with defining of emerging themes related to students' motivation to teach. It had two levels of data collection: survey questionnaire to gather student's perceptions about teachers and teaching as a profession and a focus-group discussion to validate salient themes that emerged from the responses to the survey questions. The findings revealed that early exposures to the role of teachers and influence of close family members contributed to the preference to pursue education as a program in tertiary education . Moreover, the student-participants had positive regard for teachers and the teaching profession. The students described their teachers as having positive personal characteristics, which served as model for them. On the other hand, the positive and negative perceptions regarding the teaching profession surfaced. Lastly, the study recommends that orientation programs include parents of students and model teachers of the schools to strengthen the students' interest to pursue teaching.
