Reflection on Conducting Qualitative Research: Principal Issues and Practical Solutions in Indonesia
Authors: Rohmah Dewi Wardah Mazidatur , Aliah Nuraziza
Published: February 2023

Every year, a large number of senior university students in Indonesia will/ have experience in conducting qualitative research. Some of them choose qualitative research because they understand that their questions only can be answered through qualitative research. While the rest of them only see that qualitative research is may be simpler than quantitative research because no need to calculate the numbers and do statistical trial. Unfortunately, many of these students who start their new role as novice researchers don’t have sufficient knowledge on some issues before doing this research. This paper aims to provide clear and practical elaboration of some principles in qualitative research which are frequently absent and become the common malpractices by novice researchers. Some practical solutions are discussed as well. In the end, conducting ideal qualitative research in Indonesia is not only the responsibility of expert researchers but also stakeholders, lecturers, and students.

Differential expression of BMPR2 in pancreatic cancer.
Authors: Mamoor Shahan
Published: February 2023

Cancer is a leading cause of death and pancreatic cancer is among the most lethal cancers (1, 2). We mined public and published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with pancreatic cancer, pancreatic adenocarcinoma (PDAC). We found significant differential expression of the gene encoding bone morphogenetic protein receptor type 2, BMPR2, when comparing pancreatic tumors to the tissue of origin, the pancreas. BMPR2 mRNA was present at significantly lower quantities in tumors of the pancreas as compared to normal pancreatic tissue. Analysis of human survival data revealed that expression of BMPR2 in pancreatic tumors was correlated with overall survival in patients with pancreatic adenocarcinoma. BMPR2 expression changes may be important for the initiation or progression of human PDAC.
Who Thinks COVID-19 is not a Crisis? Need for Cognition and Political Ideology Influence Perceptions of the Severity of COVID-19
Authors: Meerza Syed Imran Ali , Brooks Kathleen R. , Gustafson Christopher R. , Yiannaka Amalia
Published: February 2023

The main objective of this study is to identify the role of the need for cognition (NFC) and political ideology in shaping perceptions of the severity of the COVID-19 pandemic using survey data collected from 1,223 individuals in the United States. Our results suggest that participants with a high NFC are more likely to perceive COVID-19 as a crisis than respondents with a low NFC. Moreover, empirical results indicate that conservatism is related to perceiving the COVID-19 pandemic as less severe. Specifically, individuals on the ‘right’ of the political spectrum (i.e., conservative) were less likely to perceive the COVID-19 pandemic as a crisis than individuals on the ‘left’ of the political spectrum (i.e., liberal). Overall, study findings show the psychological and political roots of individual differences in perceptions of the severity of the pandemic.

Published: February 2023

Anxiety disorders, one of the most common classes of psychological disorders, have been shown to result in a decreased quality of life. Although some research suggests that anxiety disorders are linked to impairments in executive functioning, the inconsistency in the current literature yields an unclear conclusion on the relationship between the two. The current meta-analysis systematically investigated 55 records (N=4601; kReactionTime=44, kAccuracy=79) that compared various groups with anxiety disorders to healthy controls on executive function tasks. Overall, our meta-analysis showed that individuals with anxiety disorders exhibited significant deficits in performance efficiency (reaction times) on executive function tasks. However, we also found that individuals with anxiety disorders may outperform their healthy peers in performance effectiveness (task accuracy) in some conditions. Type of anxiety disorders, domain of executive functions, and mediation use were identified to moderate the overall relations between anxiety disorders and executive functioning. Nevertheless, the results were robust across important demographic and other clinical moderators (e.g., anxiety severity and comorbidity).
Participation in formal adult education and family life - a gendered story
Authors: Pöyliö Heta , McMullin Patricia
Published: February 2023

Previous literature on adult education has focused on various aspects of social inequalities, and although many acknowledge the important role of gender, the mechanisms influencing gender differences in participation are rarely to the fore. Specifically, women report family responsibilities as the main reason not to enrol in adult education (AE). This paper examines how family life influences enrolment in formal AE differently between men and women in two societies with highenrolment rates; Finland and Great Britain. Data from Finnish registers and Understanding Society is used to derive empirical evidence on the multidimensional work-family-education nexus. The results demonstrate clearly that family responsibilities restrict women from participating in formal adulteducation to a higher extent than men in Great Britain, but the picture is less gendered in Finland. Further, while Finnish society enables individuals who traditionally have fewer resources to attend formal AE (single parents, larger families), adult education in Britain is mainly taken up by individuals without children or by those in stable family situations. The results indicate the importance of institutional differences in providing equal access to further educational qualifications.
“MATERIAL RELIGION” AS A METHOD IN SOCIAL ANTHROPOLOGY AND THE PROBLEM OF THE RESEARCHER’S ACCESS TO “REAL” RELIGIOUS EXPERIENCE (CONCLUSION)
Authors: Shtyrkov Sergei
Published: February 2023

The methods of “material religion” elaborated in social anthropology and the materialistic (Marxist) approach to the study of religious life are methodologically different ways of turning our accustomed understanding upside down: the spiritual activity of Homo religiosus, acting as generating source, produces something material—sacred images, houses of prayer, and objects of worship. The method of material religion involves determining how the culturally specific sensory experience of the individual generates that which is interpreted by this individual, their fellow believers, and external observers—who usually receive accounts of such states in narratives—as actual religious experience. But behind what is read as a replica of the spiritual, disembodied world there is always the work of man, which, however, can be difficult to recognize in this quality. The Marxist materialist perspective, inevitably sharpened critically against religion as a typical ideology, seeks to find a basis for spiritual life in the economic conditions of human existence and society, which in this tradition of understanding human nature, are inevitably linked to labour. These two research traditions, which have the potential to enrich each other, remain in different segments of the academic field. One possible common ground for a collaborative project for these two perspectives is the study of infrastructural aspects of religious life. Another collaborative project could be the very work of social anthropologists who, using their bodies and intellect as their most accessible and potentially inalienable research tool, produce experiences comparable to those of believers and translate them into the terms of social science.
“THIS, THEY SAY, IS YOUR LOCAL PLACE OF POWER”: SPIRITUAL TOURISM ON SEYDOZERО THROUGH THE EYES OF GUIDES ON THE KOLA PENINSULA
Authors: Davydova Alena , Shtyrkov Sergei
Published: February 2023

So-called spiritual tourism, the most important part of which is travelling to “places of power”, is a dynamically developing trend in the tourism industry. However, the market for services in this field is far from being transparently and pragmatically structured in every place. Sometimes it is consistently transformed through the creation and promotion of an easily recognisable consumer product offered by specialised entrepreneurs. Somewhere, however, this market develops using the resources of structures already present in the field that were not specifically designed for it. The purpose of this study is to analyse certain aspects of the process, which can be defined as the arrival of a new consumer where they have not been expected, where the tourism industry is defined by a long-established infrastructure. The guides who provide travel to familiar geographical locations are an important part of this infrastructure. They are faced with new tourists to whose unusual practices they have to adapt. Among other strange things, guides have to deal with the fact that their clients have a habit of attributing meanings to local objects that are unknown to the guides themselves. In other words, these “guests” bring with them something that is usually produced by the “hosts”, local people who are supposed to be privy to local knowledge. But the particular history of settlement in this region creates in the guides a sense of a lack of authentic information about the past of these places. Under these circumstances, in an attempt to create the necessary historical narratives, they enter into difficult negotiations with their clients about what kind of past the most popular spiritual tourism destination in the Murmansk region, Seidozero, should base its reputation on.
TO BUILD A BUDDHIST TEMPLE: INFRASTRUCTURE AND NON-CANONICAL PILGRIMAGE VALUES
Authors: Guchinova Elza-Bair
Published: February 2023

The aim of this fieldwork-based paper is to show the path to the businessman’s faith in the modern historical, social, and confessional context, as well as the language in which it is articulated. The decision to build a Buddhist temple “turnkey” to replace the one destroyed in the 1930s, in his home town leads to spiritual transformation. Buddhist teachers, who have unconditional authority, change the outlook and behaviour of the benefactor. The author examines the infrastructure and itinerary reflecting the political geography of the modern Buddhist world and the goals of the informant’s numerous travels. Special attention is paid to the experience of the “miraculous”, which emphasizes the confessional character of these regular travels and is one of the markers of faith. The interview material highlights a close connection between the confessional Buddhist affiliation and the ethnic identification of the Kalmyks, which was not so obvious a few decades ago. The language of spontaneous narrative shows the complexity of the respondent’s worldview, which combines Soviet and non-Soviet values.
A Review of AMIRA MITTERMAIER, GIVING TO GOD: ISLAMIC CHARITY IN REVOLUTIONARY TIMES. Oakland, CA: University of California Press, 2019, XIV+233 pp.
Authors: Tereshina Daria
Published: February 2023

Amira Mittermaier’s book examines the practices of Islamic charity in contemporary Egypt. To answer the question of how and why pious Muslims engage in charity in their mundane lives, the author visits not only mosques, shrines, charitable and volunteer organizations, but also Tahrir Square in Cairo, an important locus for understanding Islamic piety. The place became widely known in 2011 due to the massive anti-government protests that came to be known as the Arab Spring in Egypt. The study of political activism allows the author to get a better grasp on the ordinary ethics of Islamic charity that considers the issues of social justice to be no less important compared to the political activism. But unlike liberal emancipatory projects, the understanding of social justice within the framework of Islamic piety relies on a fundamentally different ethics, political ontology, and temporal orientations. Drawing upon different cases, Mittermaier demonstrates the diverse ethical repertoire of Islamic giving, ranging from the examples of radical asceticism and self-denial, based on the Sufi ideal of the gift, to the more utilitarian approaches to charity, where gift exchange is considered to be a means to collect divine rewards for performed virtues. By comparing the Islamic gift ethics with the secular projects of social restructuring and reducing poverty, the author urges the reader to rethink Islamic charity as having a specific political meaning and potential vis-a-vis progressive ideas and politics.
A Review of T. M. LUHRMANN, HOW GOD BECOMES REAL: KINDLING THE PRESENCE OF INVISIBLE OTHERS. Princeton, NJ: Princeton University Press, 2020, XV+235 pp.
Authors: Masagutova Marie
Published: February 2023

Tanya Luhrmann’s new book is a great example of an academic text turning into a bestseller. The book, based on many years of fieldwork, addresses the issue of faith. The author argues that faith is not given and predefined, and instead should be seen as a long and complicated process of “real-making”—the individual’s effort to build up social relationships with the invisible Others. Throughout the chapters, the author consequently develops her argumentation, advancing from the thesis about the difference between the reality of material objects and spiritual beings to the proposition that interaction with supernatural actors changes people and their lives. The author reflects on the importance of a detailed narrative of the imaginary or invisible world (whether spiritual or fictional) in order to experience it as real, demonstrates the role of innate and kindled qualities for the perception of the religious experience, and explores the specificity of the prayer state and the signs which people perceive as a response from a supernatural actor. The review discusses the specificity of the author’s approach to the analysis and the research question itself, highlighting some possible subjects as a material which could productively complement Luhrmann’s analysis.
MARTHA’S LADLE: AN ANTHROPOLOGY OF RELIGIOUS INFRASTRUCTURE
Authors: Kormina Jeanne , Khonineva Ekaterina , Shtyrkov Sergei
Published: February 2023

The infrastructural turn in the social sciences comes from a tendency to change the anthropocentric epistemology in social research. This new approach corresponds to the classic program of social anthropology as it makes the known unknown and provides one more perspective which helps reveal the invisible politics, inequalities, and social tensions. Yet, when it comes to the social research in the field of religion, the interest to how infrastructures work has not resulted in new academic discourses and research practices so far. This article outlines some directions and topics in the anthropology of religion which stem from the infrastructural turn. First, it highlights the work of the social imagination of believers when they deal with thick or thin (poor) infrastructural systems. Secondly, it discusses the moments of infrastructural breakdown which provoke believers to generate semiotic ideologies in order to represent their experience of communication with non-human agents, both mundane and divine. The infrastructural approach to understanding religious life does not pretend to become a new research methodology or social theory. Rather, it suggests that thinking infrastructurally on typical topics for anthropology of religion, such as pilgrimage, charity, memory or historical imagination, helps us to better understand the logic which shapes the everyday life of a religious person and community. Furthermore, it helps us remember that religious and secular domains of life are usually not separated in ethnographic reality.

Published: February 2023

The search for new plant growth regulators that have an adaptogenic and protective effect, for example, in polluted with heavy metals environment, is of great interest. Under the requirements for the environmental friendliness, natural products can be considered as prospective sources of such biologically active substances, for example, the fruiting bodies of xylotrophic fungi, which are widespread in the forests of Russia. In this work the joint and separate effects of cadmium ions and extracts from four species of xylotrophic basidiomycetes – Inonotus obliquus, Fomes fomentarius, Fomitopsis pinicola, and Ganoderma applanatum – on the mitotic index and frequency of mitotic aberrations were studied in barley plants. The Hordeum-test showed that an increase in the concentration of cadmium ions in the growth medium in the range from 100 to 2000 µM caused an increase in the percentage of chromosome aberrations, while the mitotic index in experimental plants decreased by no more than 10% in the case of 100 and 200 µM Cd2+ compared with the control, and at high concentrations, its fall was 15-46%. The addition of tinder fungi extracts to the medium without addition of cadmium ions did not lead to the chromosomal aberrations in cells, and mitotic indices remained at the control level, except for the chaga extract, which caused an inhibitory effect on the mitotic activity in barley root cells. The combined use of extracts of xylotrophic basidiomycetes and cadmium ions reduced the cytotoxicity of the latter: the use of extracts of all four fungal species prevented chromosomal aberrations. The extracts of chaga and Ganoderma applanatum had the greatest protective effect on the ability of meristem cells to divide. Thus, these two species can be considered as promising natural sources for biopreparations with a protective effect perspective for agriculture use.

The pectin-silver (Ag) nanocomposites were obtained in a mass ratio of 10:1 or 25:1 by silver nitrate chemical reduction by Citrus and Classic pectins with molecular weights of 141 and 89 kDa and the degree of etherification of 80 and 38%, respectively. The barley seed germination, growth parameters of 7th day seedlings and the fungicidal effect of the initial concentration and dilutions of 10, 50 and 100 times were determined. The infection process on the 3rd (onset of the disease) and 6th days (intensive development of the disease) was evaluated on leaf segments placed in the studied nanocomposite solutions. They were inoculated by conidia suspension (3-5 thousand/ml) pathogens of net and dark brown spots of barley (Pyrenophora teres and Bipolaris sorokiniana). Seed treatments with nanocomposites did not cause a significant effect on seed germination. The nanocomposites Citrus-Ag pectin in a ratio of 10:1 increased the length and weight of seedlings, Classic–Ag pectin (10:1) undiluted and diluted 10 times increased the shoots length. The nanocomposites in a ratio of 25:1 in all concentrations caused an increase in the length and mass of seedling shoots. On the 6th day the necrotic damage area of leaf segments decreased almost 2 times in 10:1 pectin-silver nanocomposites at initial concentrations and diluted by 10 times compared to the control. During this period the photosynthetic pigments content in the barley leaf segments remained 1.8 - 2 times higher than in the infected control. Incubation on solutions of nanocomposites pectin-silver 10:1 led to a decrease in the oxidative processes’ intensity caused by necrotrophic pathogens at the initial stage of disease development, that contributed to slowing necrosis and preserving the barley leaf segments viability in the model experiment.

The gene pool of the native population of the dark forest bee Apis mellifera mellifera is gradually being lost due to spontaneous introgressive hybridization with bees of the southern subspecies, which are imported into the forest and forest-steppe zones for commercial beekeeping. The aim of the study is to evaluate the effectiveness of preserving the gene pool of the dark forest bee A. m. mellifera in the biosphere reserve "Bashkir Urals" using genetic markers. It has been shown that the Q variant of the mtDNA of the COI-COII locus, which characterizes the southern subspecies of bees, occurs with an insignificant frequency in bee colonies on the territory of the Bashkir Urals Biosphere Reserve. The PQQ variant of the locus COI-COII mtDNA occurs with a high frequency in bees nesting in natural and artificial nest in tree trunks. The proportion of the Q mitotype is significantly higher in apiaries, as well as in natural and artificial nest in tree trunks in areas of the reserve without a strict protection regime. When using nine microsatellite loci, a tendency to an increase in allelic diversity in local populations with a higher occurrence of the Q mitotype was revealed. Based on the identified patterns, strategies are proposed to improve measures to preserve the gene pool of the population of the dark forest bee A. m. mellifera.

Published: February 2023

In the last decade, significant progress has been made in the study of plant analogues of mammalian and human hormones. If, just as it happens in an animal cell, these compounds act as regulators of metabolism, the question arises about the existence of receptors for them and there is a need to study the mechanisms of intracellular signaling. With help of affinity sorbent with immobilized thyroxine presumably take part in the reception of plant analogues of iodothyronines compounds were isolated from bean seedlings. The procedure of affinity isolation of receptors to the plant analogue of thyroxine with subsequent determination of the concentration of triiodothyronine in the isolated fractions was repeated 15 times (n=15). It was assumed that the concentration of binding sites of thyroxine analogues is equal to the concentration of the hormone determined in the sample by enzyme immunoassay, thus, it was assumed that the hormone binding sites were fully loaded. The calculation of the average concentration of binding sites in samples and absolute errors was carried out using the program Statistica for Windows version 10. The average number of iodothyronine (A) binding sites in picomoles per 1 gram of raw tissue mass (pmol/g) was calculated using the formula A= (C*V)/m, where C is the average concentration of thyroxine binding sites in mmol/l determined by enzyme immunoassay, V is the volume of the eluted fraction, m is the weight of the bean sprouts in grams. It is shown that the isolated compound is a nucleoprotein with a nucleic acid content of about 11% and contains binding sites not only of thyroxine, but also of steroid hormones.

The article analyzes the peculiarities of determining the physical development and motor readiness of students of higher education in the process of playing football. The dynamics of indicators of motivation and motor readiness of students during football training in the conditions of the academic year were studied. The article revealed that football is one of the most popular sports among students.

An assessment of the dynamics of motor readiness was carried out based on the results of pedagogical testing of the development of spatio-temporal accuracy of movements of higher education applicants and the formation of technical skills and skills of student youth, taking into account the level of playing skill. Therefore, the use of football characterizes it as one of the most effective means of physical training of students. That is why a detailed analysis of the use of football tools as a basic sport, characteristics of its means and combinations with other sports, taking into account their "energy intensity" and wellness efficiency, could significantly contribute to the optimization of the educational process for the physical education of students of higher education.

The use of the method of physical training of students by means of mini-football proves its effectiveness. Students increase physical fitness, motor activity, and motivation for physical education increases, which has a positive effect on their lifestyle. It develops the ability to overcome some stresses and difficulties. In the process of football classes, students have a number of important moral and volitional qualities: collectivism, purposefulness, endurance, discipline, courage. Football can be widely used as a means of professional - applied physical training of students of different specialties.

Chronic conditions associated with shoulder damage leads to a impairment in the quality of life of a patient, which can negatively affect its social realization and the work it performs.

Pain in the shoulder region can occur due to pathologies of the musculoskeletal system, including impingement syndrome, tendonitis, partial and complete rupture of the rotator cuff of the shoulder, as well as adhesive capsulitis, shoulder bursitis, shoulder instability and shoulder arthritis. These lesions are manifested not only by severe pain, but also by decreased functioning, limited movement in the joint, decreased strength. The purpose of the study is to investigate the effectiveness of integrated use of modern measures of physical therapy for shoulder injuries. Theoretical and empirical research methods were used: analysis, generalization, comparison and ranking of the obtained information, observation, experiment, statistical methods.

The study was conducted among a group of people with a chronic condition of the shoulder. It took place on the basis of a yoga studio in Dnipro. Eleven participants (5 women and 6 men) were selected and underwent physical therapy classes twice a week for 8 weeks. Among the means of physical therapy were used joint mobilizations according to the concept of Mulligan, means of the PNF method, classical and modified yoga exercises.

The proposed program of physical therapy of shoulder lesions in patients with low and medium pain and limited range of motion in the joint showed high efficiency, almost all indicators were reliable.
