Economic War and Multipolar Economic World
Authors: Ashik Syod Ahsanul Islam , Afroje Sahariya , Hossain Nazmul
Published: November 2022

This is an everchanging and ever-competitive global arena. It’s called globalization of economic affairs. After the WWII a significant number of international financial institutes and economic mechanisms including World Bank, IMF, SWIFT System, WTO (GATT), International Stock Exchanges as well as global Reserve currency have been developed to create a borderless economic world, called American World Order. Due to global market economy and borderless economic world whole world has become a global village and the movement of goods, capital and people has been eased and widened. Economic activities have been faster, diversified, and widespread in one hand and on the other hand the outer influence on an economy has become very significant. Inter-exchange of products and services and inter-dependability among the nations are the global scenarios in the modern world. On the contrary, these financial institutions and economic mechanisms are being used as western leverage and being politicized and weaponized to counter the rival states, causing economic volatility in national and global levels during last several decades. The main purpose of the study is to analyze the impacts of outer influence and politicization & weaponization of economic mechanism and international financial institutions on a particular economy and on global economy in large and potential ways to overcome the challenges. The study is mainly based on secondary sources of data including scholarly journal, articles, books, research materials, news of media outlets and other relevant sources pertaining to the subject. The finding of the study will contribute to counter the unusual economic situation, deter the counterproductive economic measures of hostile outsiders and suggest a mechanism and framework for an Alternative Economic System to form a multipolar economic world to neutralize the western domination.
Women in Flower Farms: The Impact of Flower Growing on Gender Roles in Uganda
Authors: Sendawula Noah , Charles Omulo Owenda
Published: November 2022

The study recognised the obvious impact of survival pressures and work dynamics on gender roles in society and thus assessed the impact of flower growing on gender roles in rural communities. Using a mixed methods research approach, the study focussed on Wagagai and Fiduga farms in Uganda due to their vast sizes and high employment levels compared to related farms. Data was collected using both primary (questionnaire, interviews, FGDs and observation) and secondary (documentary review). A sample of 362 participants (322 questionnaires and 40 interviews) were purposively selected. Thematic and content analysis techniques were utilised in qualitative data analysis while descriptive statistics (mean, Std. Dev, multiple regression and impact estimation techniques) were utilised in quantitative data analysis. From the field findings, it was established that with the increased absence of women at home due to work engagements in flower farms, men were increasingly engaging in home care duties. This is against a widely held ethnic practice and norm as well as cultural dictate that men should not be in the kitchen. Study findings further revealed that, there was an increased feeling among men that by employing more women, flower farms were systematically destroying the bond that had kept families together in their local communities. This was supported by evidence of sizeable number of single mothers working in flower farms. The study recommended that there should be increased counselling of couples regarding the changing nature of gender roles.

Unearthing Constraints Experienced by Teacher Unions in Improving the Learning Environment in Schools in Zambia
Authors: Sinkala Henry , Simui Francis , Muleya Gistered
Published: November 2022

The study unearths constraints experienced by teachers' unions in promoting a peaceful learning environment in selected schools of Lusaka, district, Zambia.  A case study design was employed on a target population that comprised participants from primary and secondary schools and teacher unions. Expert purposive sampling technique was applied to sample 28 participants from teacher union officials in Lusaka District. Data generated was through interviews and Document Review which was analyzed using themes. Emergent findings revealed that the teachers’ unions faces a myriad of challenges such as inadequate resources, limited knowledge and skills, inaccessible leadership and inadequate financial support in their quest to contribute to a peaceful school environment.  Thus, it is recommended among others that, Unions should consider  building capacity on resource mobilization and optimal resource utilization, as well as enhancement of mutual consultations with the Ministry of Education and teachers to discuss matters relating to how they can contribute towards raising the standards of learning environment in schools.
The Investigation of a Middle School Teacher Preparatory Program Through the Lens of Invitational Leadership
Authors: Price- Richardson Christina L. , Martin Barbara N.
Published: November 2022

Using the principles and domains of invitational leadership identified by Purkey and Novak (2016), the researchers focused specifically on the inclusion of caring, respect, trust, optimism, and intentionality throughout the domains of people, places, policies, programs, and processes for creating an inviting culture in a teacher preparatory program. The results concluded the program was effective at including many of the principles through the domains of invitational leadership by role modeling, building relationships within the community of learners, and offering collaborative opportunities to the students. However, often this use was unintentionally inviting indicating that there was a need to further study invitational leadership theory to implement it effectively.
An Appeal for a Creaturely Attitude to Animals in Vasily Rozanov’s Writing
Authors: Mondry Henrietta
Published: November 2022

The work of Vasily Rozanov offers a relevant case study of our changing relation to natural-cultural contact zones with animals. Rozanov used a comparative approach to human-animal connections to change the societal attitude to the physical body and erase boundaries between human and animal corporeality. I focus on his narratives that promote a creaturely attitude to animals in the context of societal problems. The issues he addresses have special relevance to the current pandemic realia. I argue that Rozanov used both ethico-religious and secular arguments, as well as logic and emotion as part of his strategy to appeal to wider audiences. The hybrid genre of his narratives was a new form of literature that employed multiple rhetorical devices in creating creaturely poetics.
Етика інтерпретації знакових текстів
Authors: Поліщук Ярослав
Published: November 2022

The main subject of the review is Mykola Ilnytskyi’s book Reading and Re-reading…, which is very important research on Ukrainian literature in contemporary humanities. The book includes four chapters in all of which fundamental interests of the researcher are described. Mykola Ilnytskyi reviews the classic texts of Taras Shevchenko, Ivan Franko ( chapter 1 ), and the literature of the first part of the 20th century ( chapter 2 ), as well as contemporary texts ( chapters 3, 4 ). This book is not an extensive view of the history of literature of the 20th century. Its main peculiarity is the delivery of important fragments and episodes of literary history. The essays combine a liberal understanding of the subject and an unobtrusive interpretation of the texts, which reflects the unique ethical culture of the researcher. Mykola Ilnytskyi is clearly aware of the multiplicity of meanings offered byfiction, and therefore does not insist on his own right to the truth, but only offers well-founded and personally verified versions of literary plots.

Zalijepljena priroda: albumi sa sličicama životinjske i biljne tematike u jugoistočnoj Europi iz ekohumanističkog očišta
Authors: Đurđević Goran
Published: November 2022

Collecting sticker albums is part of growing up, learning, and having fun formany children in Southeast Europe from the mid-1950, when the first picture albums appeared, until today. Among the most famous examples are sticker albums with plant and animal themes analyzed from ecohumanities perspectives, i.e., the permeation of Nature and Culture. While most authors start from thecontent ( textual and visual analysis ), the author of this paper takes a completely different perspective. After the analysis, four major periods are visible ( the early 1970s, second half of the 1980s, second half of the 1990s and early 2000s and the period from 2013 to 2018 ) in which the increase in the number and quality of the mentioned albums correlates with a greater presence of green policies and politics.
Ekokritika i geopoetika: ekopsihološki pejzaži
Authors: Đurković Uroš
Published: November 2022

Based on comparative research on ecocriticism and geopoetics ( Kenneth White) as two theoretical discourses concerning the relationship between literature and environment, the aim of this paper is to explore the connection between literary landscapes and their psychological foundation. Ecocriticism, as a dynamic, complex, and sometimes inconsistent system of thinking about nature and literature, can be enriched byWhite’s geopoetics, which has not only a theoretical but also an important practical dimension. A question of landscape in art is viewed, through these theoretical positions, as one of the crucial moments for personal and collective human self-identification in environment.

Model miasta zwartego w kontekście prowadzonej polityki mieszkaniowej na przykładzie doświadczeń wiedeńskich
Authors: Samorek Barbara
Published: November 2022

Włączenie sfery mieszkaniowej w zintegrowaną politykę rozwoju poprzez wdrażanie modelu zwartych struktur przestrzennych stanowi rzeczywistą szansę przeciwdziałania negatywnym trendom urbanizacji. Studia nad gospodarką mieszkaniową Wiednia – zaawansowaną w działaniach i skuteczną w realizacji – pozwalają na zidentyfikowanie w obrębie polityki miejskiej dobrych praktyk, sprzyjających koncentrycznemu kształtowaniu tkanki urbanistycznej. Analiza doświadczeń wiedeńskich oraz wyróżnienie związków pomiędzy cechami polityki miejskiej a kierunkiem wzrostu ośrodka dają podstawy do uznania, że mieszkalnictwo jest skorelowane z planowaniem przestrzennym. Autorską częścią pracy jest zainicjowanie badań nad problematyką polityki mieszkaniowej miasta zwartego. Stanowi ona otwartą koncepcję rozwoju, odpowiadającą na przestrzenno-funkcjonalne oraz społeczne przemiany współczesnych aglomeracji.
Government transfers in the budgets of Polish municipalities and their determinants
Authors: Wichowska Anna
Published: November 2022

The level of transfer payments, factors that determine the allocation of public resources to territorial governments, and fiscal decentralization have been studied extensively for many decades. These problems have recently resurfaced in the scientific debate in the face of the economic crisis triggered by the coronavirus pandemic. The study has two aims: to evaluate the vertical redistribution of public funds to Polish municipalities, and to identify the economic factors that influence the level of transfer payments. The poverty rate and the average monthly disposal income in Polish municipalities were among the key determinants of public transfer levels.

Published: November 2022

Celem artykułu jest analiza strategii inwestycyjnych w infrastrukturę gospodarki komunalnej na przykładzie gmin powiatu olsztyńskiego. Po wejściu Polski do Unii Europejskiej w strategii inwestycyjnej gmin dominował trend związany z pozyskaniem jak największych środków finansowych na projekty z obszaru gospodarki komunalnej. Wraz z nasyceniem infrastrukturalnym kierunki inwestycyjne gmin zaczęły ewoluować. Głównymi czynnikami mającymi wpływ na zamianę kierunków inwestycyjnych jest: wzrost świadomości społeczeństwa odnośnie do konieczności zwiększenia wysiłków na rzecz ochrony środowiska, ochrony zdrowia, ograniczenia wpływu negatywnych zmian klimatycznych. Badania potwierdzają zmianę kierunków inwestycyjnych badanych gmin, co wyrażone jest rodzajem i liczbą zrealizowanych projektów inwestycyjnych w zakresie gospodarki komunalnej.

Wpływ wynagrodzeń na wzrost gospodarczy regionów Polski i Ukrainy
Authors: Shubalyi Oleksandr , Miszczuk Andrzej
Published: November 2022

Celem artykułu jest analiza trendów i ocena wpływu dynamiki przeciętnego miesięcznego wynagrodzenia na wzrost gospodarczy w regionach Polski i Ukrainy, mierzony PKB per capita w latach 2004–2019/2020. Wyniki przeprowadzonego badania pokazały, że średnio w Polsce i w prawie wszystkich jej regionach (poza lubuskim i świętokrzyskim) wzrost przeciętnego miesięcznego wynagrodzenia ma bardzo pozytywny wpływ na wzrost PKB per capita. Sytuacja na Ukrainie jest mniej optymistyczna. W dwóch regionach, w których agresja Federacji Rosyjskiej rozpoczęła się w 2014 r. (obwody doniecki i ługański), zależność między tymi wskaźnikami jest bardzo niska. Również w zdecydowanej większości regionów Ukrainy zmiana PKB per capita jest nie- elastyczna w stosunku do zmiany przeciętnego miesięcznego wynagrodzenia. Może to być spowodowane orientacją surowcową eksportu oraz niewielką liczbą branż high-tech wytwarzających produkty o wysokim udziale wartości dodanej, w których istotny jest wzrost płac. Analiza dynamiki PKB per capita i przeciętnego miesięcznego wynagrodzenia wykazała, że Ukraina dopiero w latach 2018–2019 osiągnęła wartość tych wskaźników na poziomie, którym Polska cechowała się, wchodząc do Unii Europejskiej w 2004 r.
Oral corrective feedback on lexical errors: a systematic review
Authors: Tan Xiaochen , Reynolds Barry Lee , Ha Xuan Van
Published: November 2022

This study adopted a synthetic approach to review empirical studies on oral corrective feedback (OCF) for lexical errors. It examined OCF types, lexical target types, interlocutors’ attention to lexical errors, and OCF effectiveness in promoting vocabulary development. After the application of inclusion and exclusion criteria on studies retrieved from a search of six databases, 31 primary studies were available for coding and analysis. Findings revealed that interlocutors showed a greater preference for recast than prompt and explicit correction. However, recast resulted in the lowest rate of lexical repairs, whereas prompt was found the most effective. Lexical errors received OCF at a higher rate than grammatical errors and phonological errors, indicating that interlocutors paid greater attention to vocabulary problems. OCF was most often provided for the inappropriate choice of lexical items, or inaccurate use of word derivation, involving a wide range of word classes (nouns, verbs, adjectives, and adverbs). Only a few studies looked into OCF targeting a single lexical feature. Findings suggest it may be more effective for teachers to employ prompts to elicit repairs of lexical errors from learners. There is a need for future researchers to conduct empirical OCF studies on a single lexical target.
A missense variant in NCF1 is associated with susceptibility to unexplained recurrent spontaneous abortion

Published: November 2022

Unexplained recurrent spontaneous abortion (URSA) is a major concern in reproductive medicine. Neutrophil cytosolic factor 1 (NCF1) polymorphisms leading to low production of reactive oxygen species (ROS) are strongly associated with autoimmune diseases. We investigated the association of the missense single nucleotide polymorphism (SNP) rs201802880 (NCF1-339) in NCF1 with URSA and explored its function. We performed NCF1-339 SNP genotyping of samples from 152 Chinese patients with URSA and 72 healthy controls using nested PCR and TaqMan assays. ROS production and RELA (NF-κB subunit) expression in the blood of participants with different NCF1-339 genotypes were determined. The frequencies of the wild-type (GG) and mutant (GA) genotypes remarkably differed between the URSA and control groups. The mutant genotype was associated with an increased risk of recurrent abortion. Furthermore, ROS levels in the URSA group with the GG genotype were significantly higher than those in the group with the GA genotype (p < 0.05). RELA expression in URSA patients with the GA genotype was considerably higher than that in control individuals with the GG genotype. These findings indicate that mutations in NCF1 may increase the risk of URSA via the NADP/ROS/NF-κB signaling pathway, which has implications for the diagnosis and treatment of URSA.
Research on prehistoric 凸-shaped house remains on the Loess Plateau
Authors: Wang Tianyi
Published: November 2022

The 凸-shaped house remains first appeared in the Guanzhong Basin during the late Yangshao period and became a popular form of architecture in the Loess Plateau during the Longshan period. The form usually consists of an inner room and a front hall connecting to an entranceway. The emergence of the protruding front hall is closely related to the appearance of late Yangshao cave dwellings, where they serve an important role in maintaining the architectural stability of the dwelling. Across the millennium ranging from the late Yangshao to the late Longshan, this architectural structure gradually transformed from a pragmatic-functional attribute into an important cultural symbol.
Statistical modeling and optimization of the bleachability of regenerated spent bleaching earth using response surface methodology and artificial neural networks with genetic algorithm
Authors: Williams Almoruf O. F. , Akanbi Oluwaseun D.
Published: November 2022

In this study, the statistical modeling and optimization of the regeneration of spent bleaching earth (SBE) for re-use in the bleaching of crude palm oil (CPO) oil was examined. Having a good model will assist with the successful optimal regeneration of SBE and hence minimize the environmental pollution associated with its current disposal method which is based on dumping as landfills. The SBE samples were de-oiled with the Soxhlet extraction method, using n-hexane for 1 h at 60 °C; treated at temperatures ranging from 300–500 °C; at carbonization time between 30 and 45 min; and with hydrochloric acid concentrations between 1 and 2 M, at a constant stirring time of 30 min, respectively. The operating conditions for the experiment were according to the Central Composite Design (CCD) experimental design using the Design Expert software version 13. The modeling and optimization of the SBE regeneration process was carried out with the Response Surface Methodology (RSM) and Artificial Neural Network (ANN) techniques. Five regression models were developed from the RSM approach and the best one selected based on model selection parameters recommended in the literature. Similarly, ten ANN models with the number of neurons in the hidden layer that varied from 2 to 16 were considered and the best one selected using the mean square error (MSE) and correlation coefficients (R) for the training, validation and testing performances. Results showed that the ANN technique led to a model with a better predictive ability than the RSM one. The optimum experimental bleachability of 71.5% for the regenerated de-oiled SBE was obtained at carbonization temperature of 500 °C, hydrochloric acid concentration of 2M and carbonization time of 45min. Using the Genetic Algorithm (GA), the ANN model resulted in an optimum bleachability of 70.87% with corresponding optimum factors at 468.19 °C, 2 M and 45 min, while the RSM approach gave an optimum bleachability of 73.52% at the corresponding factors of 498.99 °C, 1.57 M and 41.14 min for the carbonization temperature, acid concentration and carbonization time, respectively. The optimum experimental bleachability of the regenerated SBE achieved was 12.5% higher than that of virgin bleaching earth (VBE).
The degradation of an aromatic organic compound by Aspergillus niger var tubingensis Ed8 produces metabolites that reduce Cr (VI)
Authors: Lizardi-Jiménez Manuel Alejandro , Marín-Hernández Alvaro , Tomasini-Campocosio Araceli , Coreño-Alonso Alejandro
Published: November 2022

Chromium Cr(VI) is a highly toxic environmental contaminant for any organism, its presence in the environment is mainly due to anthropogenic activities. The use of biotechnology has been implemented for the treatment of effluents contaminated with Cr(VI).Our working group has isolated several fungi and bacteria capable of removing Cr(VI) from the culture medium. Aspergillus niger var tubingensis Ed8 is a strain that can produce metabolites which reduce Cr (VI) to Cr (III). The objective of this work was to determine the effect of sodium salicylate on the growth of this strain and on the Cr(VI) reduction system, as well as to identify the metabolites that are produced from sodium salicylate. Our results show that the Culture medium containing sodium salicylate (20 mM) inhibits strain growth compared to the control condition (0 mM). However, it increases the specific reduction capacity of Cr (VI) red/mg Biomass in order of magnitude. Analysis of the culture medium corresponding to 48 h of incubation shows the presence of catechol and salicylate diminution. In addition, as a product of the enzymatic activity of a cell-free cellular extract, after 24 h of incubation, the consumption of salicylate is detected, as well as the presence of peaks corresponding to resorcinol and catechol. Our results show that it is possible to increase the Cr(VI) reducing capacity of the Ed8 strain, depending on the composition of the culture medium.
On endomorphisms of the direct product of two free groups
Authors: Carvalho André
Published: November 2022

We describe the endomorphisms of the direct product of two free groups of finite rank and obtain conditions for which the subgroup of fixed points is finitely generated, and we do the same for periodic points.
We also describe the automorphisms of such a group and solve the three Whitehead problems for automorphisms, monomorphisms and endomorphisms for groups in this class.
We also obtain conditions for an endomorphism to be uniformly continuous when a suitable metric is considered and study infinite fixed points of the extension to the completion of the group.
Maximum electromagnetic local density of states via material structuring
Authors: Chao Pengning , Kuate Defo Rodrick , Molesky Sean , Rodriguez Alejandro
Published: November 2022

The electromagnetic local density of states (LDOS) is crucial to many aspects of photonics engineering, from enhancing emission of photon sources to radiative heat transfer and photovoltaics. We present a framework for evaluating upper bounds on the LDOS in structured media that can handle arbitrary bandwidths and accounts for critical wave scattering effects. The bounds are solely determined by the bandwidth, material susceptibility, and device footprint, with no assumptions on geometry. We derive an analytical expression for the maximum LDOS consistent with the conservation of energy across the entire design domain, which upon benchmarking with topology-optimized structures is shown to be nearly tight for large devices. Novel scaling laws for maximum LDOS enhancement are found: the bounds saturate to a finite value with increasing susceptibility and scale as the quartic root of the bandwidth for semi-infinite structures made of lossy materials, with direct implications on material selection and design applications.

Published: November 2022

In Coronavirus disease 2019 (COVID-19), it is important to evaluate disease activity and investigate possible biomarkers. Therefore, in this study, we investigated the relationship between disease activity and serum levels of possible immune activation marker neopterin in patients with COVID-19. The study enrolled 45 patients (23 females, 51.1%) treated for COVID-19. The patients were divided into two groups according to their clinical presentation: those who recovered quickly (Group 1) and those who worsened progressively (Group 2). The neopterin and C-reactive protein levels were high in all patients on admission. In Group 1, neopterin concentrations and serum neopterin/creatinine ratios were significantly higher on admission compared to Day 14 of the disease, whereas in Group 2, levels were significantly higher at Day 14 of the disease than on admission. Neopterin levels at admission were significantly higher in Group 1. The serum neopterin concentrations at admission were markedly higher in patients with a derived neutrophil–lymphocyte ratio (dNLR) > 2.8 compared to those with a dNLR ≤ 2.8 (p< 0.05). Serum neopterin levels can be used as a prognostic biomarker in predicting disease activity in COVID-19.
Caravana migrante y adolescencia no acompañada: resistencia y autonomía
Authors: Hernández Aída Silva , París Pombo María Dolores
Published: November 2022

El artículo analiza la participación de adolescentes centroamericanos no acompañados en las caravanas que atravesaron México en 2018. El objetivo es comprender la relación entre la manera en que se autoperciben, sus condiciones estructurales marcadas por la violencia y la pobreza, y las caravanas como vehículo para la movilidad. Para ello, nos ubicamos en los estudios de la adolescencia desde la perspectiva de la agencia. Nuestro análisis se fundamenta conceptualmente en la autonomía de las migraciones, el derecho de fuga y la estructura espacial de oportunidades. Los resultados que presentamos evidencian que la participación de los adolescentes en las caravanas obedece tanto al resquebrajamiento económico y a la fractura del tejido social en sus lugares de origen como a su autoconstrucción como actores sociales, lo que les permite desafiar dichas condicionantes, pensarse desde resistencia y valerse de las caravanas como un instrumento de fuga.
Shifting Border, Changing Laws: The Executive Branch of Government and the Treaty of Extradition between Mexico and the United States, 1876–1911
Authors: Valenzuela David Adán Vázquez
Published: November 2022

This article analyzes an important way in which the Porfirio Díaz government tried to empower the president to control Mexico’s northern border in the late 1870s. Just a few months after Díaz gained power, officers of the incoming administration attempted to gain exclusive authority for the Mexican executive over matters related to extradition requests. The president, Díaz’s allies argued, was responsible for the country’s foreign relations, and only he could decide on the surrender of fugitives to other nations. The article maintains that such claim aimed to build a legal apparatus that would strengthen the figure of the president to control what was then the key and problematic area of northern Tamaulipas. Furthermore, the article argues that the legal changes adopted regarding extradition matters contributed to shaping the early twentieth-century borderlands, although they failed to achieve their main objective. Thus, after the 1870s, the borderlands entered an unprecedented phase of transformation that, in many ways, revealed the inefficacy of the regime’s extradition policies.
Guerra civil y génesis institucional: la Casa de Moneda de Guanajuato y su transición al México independiente, 1812–25
Authors: Castillo Ricardo Fernández
Published: November 2022

El artículo aborda la transición en la Casa de Moneda de Guanajuato de la Nueva España al México independiente. Presenta un estudio de las estrategias institucionales que permitieron a este centro de amonedación surgir, institucionalizarse y renovarse entre 1812 y 1825. El argumento central tiene dos partes. La primera enfatiza las circunstancias bélicas y políticas propias de la transición monetaria que desembocaron en la legalización de la casa de moneda. La segunda muestra que los primeros ensayos de gestión institucional de la casa de moneda –entre ellas el arrendamiento a una compañía extranjera– desembocaron en la renovación de la ceca sin un claro predominio de alguna de las partes involucradas. En diálogo con la historia económica se sostiene que el desgaste de la guerra de independencia incentivó iniciativas de institucionalización monetaria con facetas aún pendientes por estudiar.

The decision stated that the Job Creation Law contains formal defects in the process of its formation, so that the DPR and the Government must make improvements in accordance with the procedures for the formation of applicable laws and regulations, with a maximum period of 2 years since the decision was read by the Constitutional Court. The Job Creation Law caused debate in the community, because the Job Creation Law passed by the House of Representatives brought huge losses to the community, especially in the field of labor and investment. Therefore, the polemic of the ratification of the Job Creation Law must be corrected by the DPR and the Government in accordance with applicable regulations by bringing the principle of legal certainty and the principle of openness and also justice for all communities. From this writing, the author focuses on discussing the Formal Testing of the Job Creation Law After the Constitutional Court Decision and the direction of improvements made by the government after the Constitutional Court's Decision on the Job Creation Law. In writing this article, the author also uses normative juridical research methods sourced from books and also articles that are in accordance with the theme written.

Published: November 2022

Legislation pertaining to consumer rights is required since consumers continue to face disadvantages in the fields of commerce, education, and negotiation. The adoption of Law No. 8 of 1999 protects consumers, which is a wise decision. National development theories serve as the foundation for this government-community partnership. This study looks at how Customer Protection Law No. 8 of 1999 handles the duties and rights of consumers in the food business. Legal normative research is being done here. The information was supplied by the Consumer Protection Law No. 8 of 1999 and the Food and Medicine Administration Safety and Modernization Law No. 18 of 2012. This study demonstrates that distributors of food and drink in Indonesia will have legal guarantees and protection. Maintain good standards for food and drink. To help customers make purchasing decisions, producers and distributors must clearly label all items that are offered. This rule aids purchasers in making informed decisions. Although the producer provided the information that consumers needed, some of them chose not to read it. Given that certain manufacturers may still fail to pay attention to product information, the Consumer Protection Law No. 8 of 1999 can still be necessary. Customers should be more watchful while purchasing, and producers should be more knowledgeable about product details.

The new sulfides Y3Ni0.5SiS7, Sm3Ni0.5SiS7, and La3Ni0.5SiS7 exist in the quasi-ternary systems Y2S3 – NiS – SiS2, Sm2S3 – NiS – SiS2, and La2S3 – NiS – SiS2, respectively, for which the isothermal sections at 770 K were investigated. The crystal structure of the sulfides was determined by the X-ray powder method. It belongs to the La3Mn0.5SiS7 structure type (S.G. Р63; Pearson symbol hP23), with the lattice parameters а = 0.97643(4) nm; с = 0.56377(4) nm (Y3Ni0.5SiS7), а = 0.99599(8) nm; с = 0.56583(5) nm (Sm3Ni0.5SiS7), and а = 1.02830(6) nm; с = 0.57412(4) nm (La3Ni0.5SiS7). The structure of obtained sulfides is as follows: Y, Sm, and La atoms are located in the 6с site and center trigonal prisms with two additional S atoms. Ni atoms occupy the 2а site (0.5 occupancy) and have octahedral surrounding of S atoms. The coordination number of Si atoms (the 2b site) is 4. The Ni-centered octahedra form infinite chains [Ni 6S]n.

The Conditions of Success: a Change in Bowness Model
Authors: Harillo Pla Adrià
Published: November 2022

This text presents a reformulation of the model that Alan Bowness — former director of the prestigious London’s Tate Gallery — used to represent the way in which an artist achieves success. The reasons why the modification of the cited model seems coherent are presented from a theoretical and pre-experimental perspective. The results intend to be coherent and plausible. Nevertheless, they are generic and can differ in different specific contexts. Our conclusion is that Bowness model is outdated and does not show the current paradigm of art and its market, being this reformulation necessary. On the other hand, it must be clarified that when we refer to ‘success’, we are referring to a success which is primarily economic, or derivate from the economic one.

Published: November 2022

The article discusses the concept of organisational improvisation and reveals why it is important for contemporary organisations. Organisational improvisation is more and more acknowledged as a relevant field of management research; however, heads of most organisations still believe that detailed plans accompanied by various bureaucratic procedures are important, and that improvisation is a sign of failure, is risky and is to be avoided. The article discusses the three levels of improvisation (individual, interpersonal and organisational) pointing out its possibilities and advantages. Peculiarities of organisational improvisation are provided along with the results of a case study of public institution Jazz Academy. In this way, this article is the first study of organisational improvisation in Lithuania. The aim of the article is to reveal the peculiarities of organisational improvisation.
The Role of the Artist in a Communal Art Project

Art Project Management is a limited time process and a specific way of thinking that ensures that all the project stages are carried out in a planned and structured manner, that the project is finished with successful implementation of the aim of the project (MPSI, 2016, p. 71). When analysing art projects, Dovydaitytė emphasises they are often characteristic of a process, interdisciplinarity and multi-directional relations with a wider social context (Dovydaitytė, 2014). When carrying out a communal art project in a community, an artist can perform the following different functions: facilitator, interpreter, trainer, animator, mentor, consultant, project manager. Scientists attribute functions to artists differently in communal art projects. Often, communal art projects include a professional artist who comes with one of the roles that s/he has, curates the entire process and is responsible for management and, of course, engages the community. Moreover, an artist can be not only the creator, but also the manager of the whole project. The main role of a project manager is to unite members of the community, help them collaborate, and ensure as well as evaluate the final results of the art project.

Today, contemporary design solutions require creative thinking because the original design is based on innovation and creative solutions to solve certain problems such as preservation of old traditions, cultural heritage for future generations. Design as an area of science and practical activities functions by defining specific design peculiarities. Design products in scientific literature are described as closely directly related to the process, distributed in the context of the process, ones that impact the context and alter the process further. A creative product is created when acting together with other artists and is planned for the consumer, where the globalisation of the 21st century is one of the threats to national cultures. In the meantime, the person first understands the image and terms created by the culture around him, so artists, creators of creative products, play an important role here. Cooperation is a new and inspiring means of this activity that provides power to initiate, implement and evaluate solutions that is based on not only shared responsibilities, but also partnership that strengthens communication, increases trust, empathy between organisations and satisfaction in a generally received result. Sientific problem may be raised: What are the specificities of design product development and commercialization? In realizing this problem the theoretical concept and peculiarities of design product were discussed; the stages and principles of design product development and its introduction to the market were analysed; a theoretical model of design product development was created and introduction to the market; the theoretical model was analyzed by the implementation of the project “Baltic Patterns in Ceramics: From the Past to the Future”. The methods of scientific literature systematic analysis, comparison and abstraction were employed in the research.
