Authors: Malik Safia
Published: May 2023

Globalization is a complex and multi-dimensional phenomenon. The advancement in the means of communication and technology has played the role of a catalyst in intensifying international economic, social and political integration thus accelerating the process of globalization. Pakistan, a member of the global community, competes economically and on cultural, geo-political and diplomatic fronts. Jochen Hippler and Vaqar Ahmed’s book, Global Pakistan: Pakistan’s Role in the International System, explores Pakistan’s role in the international system and the challenges posed to it due to globalization. The book comprises eleven chapters including an introduction by Jochen Hippler, former Country Director Friedrich Ebert Stiftung (FES), Pakistan.

Authors: Camargo Karina Retzlaff , Bruch Alexandre Felipe , Rodrigues Milene Lima , Retzlaff Alana Stern
Published: May 2023

Há pouco mais de uma década os resíduos sólidos domiciliares de Rio Grande, município localizado no sul da Planície Costeira do Rio Grande do Sul, passaram a ser depositados em um aterro sanitário. Este trabalho reúne dados de caracterização geológica, geomorfológica e pedológica do local do aterro e resultados de pesquisas geotécnicas sobre a impermeabilização de fundo do aterro sanitário com adição de bentonita ao solo compactado. Estas pesquisas foram realizadas com dois solos locais, um superficial e outro subsuperficial, e duas jazidas. Para estes ensaios foram variados teores de bentonita e energia de compactação. Em síntese, o solo MBAR foi o único que na condição natural apresentou valores de condutividade hidráulica abaixo do permitido para uso como liner, o solo natural requer um teor de bentonita de 14% e solo ARMAR requer entre 4 e 6% de bentonita, dependendo da metodologia adotada. Esta nova solução constitui opção para o próprio empreendimento em futuras intervenções ou para outras obras de similar escopo, num mesmo contexto geológico-geotécnico. Quanto à sorção de íons, misturas de solo ARMAR e bentonita apresentaram resultados aceitos pela legislação vigente. Resultados de ensaios de cisalhamento direto evidenciaram a significativa redução no ângulo de atrito efetivo e uma anisotropia importante das misturas de solo-bentonita, o que são indícios de que a análise do comportamento mecânico destas misturas deva ser detalhadamente realizada antes do seu uso.
JOHN CALVIN DAN PERJAMUAN KUDUS: SEBUAH PROPOSAL BAGI PRAKTIK DI GEREJA BETHEL INDONESIA
Authors: Winardi Daniel
Published: May 2023

This research intends to give a proposal concerning the practice of the holy communion in Gereja Bethel Indonesia (GBI) based on John Calvin’s theological thought. As one of the largest Pentecostal church in Indonesia and even further, as a Holy Spirit-centered church, GBI has not yet given a ‘room’ for Holy Spirit to unite the church with Christ through holy communion. In general, the holy communion practice is done as a memorial act upon His crucifixion that not only save the world, but also able to heal physical ailments. This study is using literature study to explore some material sources from GBI that contain the church’s doctrine, the primary source of John Calvin’s theological idea from his writings, and also secondary sources from theologians that has been exploring this issue. The researcher’s perspective and experience of being a member of GBI also cannot be dismissed to contribute in this study. I argue two things: 1) that Calvin’s theology on ‘spiritual presence’ about the union with Christ through the work of the Holy Spirit can be a beneficial contribution to the practice of the holy communion in GBI and it is not conflicting each other, considering the work of the Holy Spirit is a central doctrine in the life of Pentecostal congregation; 2) The act of faith in the GBI context might be a necessary role in believing the work of the Holy Spirit in holy communion. Researcher also give some potential challenges and solutions to consider in doing this proposal.

Research Methods in Vocabulary Studies [Review]
Authors:   Victoria University of Wellington, Heidari Kamal
Published: May 2023

[First paragraph] Vocabulary development is a cornerstone in second language acquisition, without which communication is almost impossible. Vocabulary is by nature a dynamic and complex phenomenon. It is dynamic in the sense that it is marked by constant development in learners. It is also complex because it consists of a multitude of components and sub-components. Knowing about the most recent findings in vocabulary, especially from research and learning perspectives, is essential for researchers interested in the vocabulary domain of language as well as for teachers if they wish to function efficiently in their profession. Research that deals with vocabulary from both theoretical and practical angles is, however, limited. Being cognizant of this gap, Philip Durrant, Anna Siyanova-Chanturia, Benjamin Kremmel, and Suhad Sonbul, who are among the leading figures in vocabulary research released “Research Methods in Vocabulary Studies” to provide insightful information to readers on theories and research practices of vocabulary.

Authors:   Shenzhen University, China, Zhang Danyang , Wu Junjie Gavin ,   Shenzhen Technology University
Published: May 2023

English language education nowadays is not merely about the instruction and acquisition of linguistic knowledge and skills. Instead, it has progressed to the real-life applications of the target language, which further requires a mastery of cultural knowledge and skills. In terms of culture, English as a Foreign Language (EFL) learners, compared to native speakers of English, own their unique native culture. Yet, since language teachers tend to focus on the delivery of English cultural knowledge, EFL learners’ native culture is sometimes shadowed in the mainstream English classrooms worldwide. To this end, this exploratory paper aims to advocate attention to the importance of EFL learners’ native culture awareness and share some practical teaching and learning experiences in an English course called Multimedia and Foreign Language Learning. The paper outlines the pedagogical design of the course in China, providing classroom examples and practical suggestions to course designers, educators and instructors. We expect to give insights into integrating native culture into foreign language education in university settings.

Challenges and Opportunities for Public Sector Administration in India
Authors: Panja Saurandhri
Published: May 2023

In this paper, we analyze the difficulties and potentials of India's governmental administration. In India, the government is in charge of providing everything from public protection and healthcare to public schools and hospitals. However, bureaucratic inefficiency, corruption, political interference, and inadequate facilities are just some of the problems plaguing India's public sector. These problems have made it harder for government agencies to provide essential services to the public and damaged citizens' faith in those agencies. On the other hand, there are many ways in which Indian public administration can improve public service delivery, increase accountability and openness, and boost the country's economy. Recent studies have shown that e-governance, human resource development, and public-private partnerships can help India's public sector management overcome some of its current problems. The public sector administration in India needs to take a holistic and coordinated strategy that includes reforms in governance, infrastructure, and human resources in order to meet the challenges and take advantage of the opportunities. The government must also establish conditions that invite involvement from the private sector, push for technological advancement, and reward public accountability. Sustained effort and commitment from all parties involved are necessary to effectively handle the challenges and opportunities facing public sector administration in India. These kinds of reforms are necessary if India's public sector is ever going to meet the requirements and fulfill the hopes of its constituents.

Authors: Kurusatienkit Chomsiri Yada
Published: May 2023

The effects of environmentally responsible administration on business effectiveness are the focus of this analysis. Combining quantitative poll data from 200 managers across sectors with qualitative case study analysis was the methodology we settled on. The poll responses were analyzed using descriptive statistics, and the premise that sustainable management techniques improve corporate performance was tested using inferential statistics. Case study analysis's anecdotal data added to our understanding of how sustainable management practices boost productivity in businesses. Sustainable management techniques were discovered to have a statistically substantial, favorable association with business success. Sustainable management techniques were found to have a positive effect on company success. By analyzing case studies qualitatively, we learned that sustainable management practices can boost corporate performance in a number of ways, including through increased employee involvement, strengthened partner relationships, and a more reputable brand. Our research suggests that ecological management techniques can have a major impact on business success. These results have substantial ramifications for managers and lawmakers alike, as sustainable management practices can be an effective means for businesses to boost performance and obtain an edge in the market. In order to better understand the connection between sustainable management practices and enhanced organizational performance, future studies will need to use a larger group and focus on the particular processes by which these practices work.

Equity of Carbon Pricing Policies in Mitigating Climate Change: A Comparative Study of Different Policy Designs
Authors: Kesor Chhoub
Published: May 2023

Carbon pricing policies are investigated for their efficacy and fairness in reducing greenhouse gas emissions in Asian nations. Through an examination of various policy frameworks, we conclude that carbon pricing policies are the most promising for lowering global warming pollution. However, the distributional effects of these policies on family income are not uniform. We find that rebates or investment in renewable energy are effective revenue recycling methods for reducing the regressive impact of carbon pricing policies on low-income households. In addition, it may be easier to reach climate targets if policy designs put an emphasis on lowering emissions rather than increasing income. These results indicate that carbon pricing policies may play a significant role in reducing the effects of global warming, but that they must be designed with equity considerations in mind to be both successful and fair. Policymakers can benefit from more information about the design and implementation of carbon pricing policies across sectors, income groups, and regions in order to successfully mitigate climate change while assuring their equity.

However, most of the growth (except height) and yield contributing parameters, in all the organic treatments, were on par with RDF.Application of organic manures helped in improving available nutrients status, including micronutrients in soil. Among the different organic manures, the effect of FYM and VC in increasing the population of rhizosphere microorganisms was more than other treatments. Net return was found more in T4 (`124446/ha) followed by T3 (`118179/ha) and RDF (`114079/ha). It was found that organic manure applied in equal proportion (T4) and 100% substitution of N through neem cake (T3) was found better in getting higher yield and returns.

Experiments under the polyhouse were conducted for two consecutive years (2021 and 2022) at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-J), Jammu and Kashmir to evaluate the effect of different growing substrates on guava (Psidium guajava L.) multiplication through cuttings. Twelve substrate combinations were tried in polybags and polytrays under a polytunnel in a polyhouse provided with mist irrigation. The study revealed a positive effect of different growing substrates on growth parameters and successful propagation of guava cuttings. The perusal of the pooled data revealed that T9 was the most effective growing substrate which recorded maximum rooting percentage, survival percentage, plant height, fresh and dry weight, the diameter of thickest sprout, shoot length, length of longest root, leaf area, and the number of roots, shoots, leaves per longestshoot along with minimum mortality percentage and days to first sprouting. However, some growth parameters such as stem thickness, chlorophyll percentage, number of sprouts, sprouted cuttings, and leaves of planted guava cuttings yielded the best results in T10. Cuttings grown in topsoil only without any growing substrate (T12) provided the least values of all the growth parameters of guava cuttings.

This study evaluated the impact of contrasting tillage and nitrogen management options on the growth, yield attributes, and yield of maize (Zea mays L.) in a conservation agriculture (CA)-based maize-wheat (Triticum aestivum L.) system. The field experiment was conducted during the rainy (kharif) seasons of 2020 and 2021 at the research farm of ICAR-Indian Agricultural Research Institute (IARI), New Delhi. The experiment was conducted in a split plot design with three tillage practices [conventional tillage with residue (CT), zero tillage with residue (ZT) and permanent beds with residue (PB)] as main plot treatments and in sub-plots five nitrogen management options [Control (without N fertilization), recommended dose of N @150 kg N/ha, Green Seeker-GS based application of split applied N, N applied as basal through urea super granules-USG + GS based application and 100% basal application of slow release fertilizer (SRF) @150 kg N/ha] with three replications. Results showed that both tillage and nitrogen management options had a significant impact on maize growth, yield attributes, and yield in both seasons. However, time to anthesis and physiological maturity were not significantly affected. Yield attributes were highest in the permanent beds and zero tillage plots, with similar numbers of grains per cob (486.1 and 468.6). The highest leaf area index (LAI) at 60 DAP was observed in PB (5.79), followed by ZT(5.68) and the lowest was recorded in CT (5.25) plots. The highest grain yield (2-year mean basis) was recorded with permanent beds plots (5516 kg/ha), while the lowestwas observed with conventional tillage (4931 kg/ha). Therefore, the study highlights the importance of CA practices for improving maize growth and yield, and suggests that farmers can achieve better results through the adoption of CA-based permanent beds and use of USG as nitrogen management option.

Present field study was carried out to investigate the effects of biofertilizer strains on soil, leaf and yield parameters of Kinnow zandarin (C. nobilis × C. deliciosa) during 2018–19 and 2019–20 at the experimental orchard of Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana. The study revealed that soil, leaf nutrient status and yield parameters were significantly affected with the application of biofertilizers. There was synergistic influence of Azotobacter and PSB strains. The magnitude of increase with the application of different bio-strains was more pronounced when applied in combination with lower dose of fertilizers (75% RDF) than their combination with higher dose (100% RDF). 100% RDF + Azotobacter chroococcum Mac 27 + Pseudomonas P 36 (T7) was found most effective in enhancing soil macro-micro nutrients, leaf nutrient status and yield parameters.Soil available N and P increased significantly in 0–15 cm soil layer during both years but in 15–30 cm soil layer, the enhancement was observed only during second year of investigation, however Fe, Zn and Mn showed significant improvement only in 0–15 cm soil layer during both years. Leaf N content increased in September, however no significant effect was observed in March values. Leaf N content showed fast increment as compared to leaf P content.

Population growth causes the demand for food to increase. One solution that can be applied is agriculture with hydroponic technology. To increase production efficiency, one must know the physical parameters that most influence the production process. This research used an IoT system to gather accurate and precise measurement data of physical parameters to be used as a dataset for machine learning. The dataset consisted of light intensity, humidity, air temperature, and total dissolved solids (TDS). Plant growth was measured by leaf area of the plant, number of leaves, and plant stem length every 3 to 4 days. The models used in the machine learning process were linear regression, polynomial regression, and random forest regression. The machine learning results showed that the best model for predicting plant growth was random forest regression with an MAE of 8.3% and an R2 of 0.93, for both bok coy and water spinach. The variables that influence growth the most are TDS and light intensity. According to the relationship between TDS gradient and plant growth gradient, the most optimal growth can be achieved by raising the TDS gradient or by maintaining a high TDS, which can be achieved by adding nutrient solution to the tank regularly.
Desigualdade de renda, acessibilidade e o cotidiano das chefes de família de baixa renda em Vitória da Conquista- BA

Tendo em vista a importância da acessibilidade, especialmente às pessoas com deficiência que utilizam de cadeiras de rodas para sua locomoção, entendeu-se necessário abordar a forma como a acessibilidade, ou a falta dela, afeta a vida das mulheres responsáveis pelos seus lares e que tem renda mensal de até três salários mínimos, consideradas, portanto, como mulheres de baixa renda. Essa discussão ganha maior importância na medida em que, de acordo com dados do IBGE há um grande número de mulheres na posição de chefes de família e a falta de acessibilidade pode, de alguma forma, aumentar as dificuldades vivenciadas por muitas delas, pois ela mesmo ou membros da família podem não ter garantido o seu direito à locomoção plenamente atendido. Necessariamente a falta de acessibilidade nas áreas habitacionais se constitui como precariedade, ao mesmo tempo que não cria condições para que as pessoas com deficiência, consiga facilmente superar obstáculos. Nesse sentido é possível de se perguntar como esse problema contribui para a ampliação do trabalho da mulher de baixa renda nos assentamentos precários.
