Perturbation Free-Energy Toolkit: Automated Alchemical Topology Builder and Optimized Simulation Update Scheme
Authors: Petrov Drazen
Published: April 2021

Free-energy calculations play an important role in the application of computational chemistry to a range of fields, including protein biochemistry, rational drug design or material science. Importantly, the free energy difference is directly related to experimentally measurable quantities such as partition and adsorption coefficients, water activity and binding affinities. Among several techniques aimed at predicting the free-energy differences, perturbation approaches, involving alchemical transformation of one molecule into another through intermediate states, stand out as rigorous methods based on statistical mechanics. However, despite the importance of efficient and accurate free energy predictions, applicability of the perturbation approaches is still largely impeded by a number of challenges. This study aims at addressing two of them: 1) the definition of the perturbation path, i.e., alchemical changes leading to the transformation of one molecule to the other, and 2) determining the amount of sampling along the path to reach desired convergence. In particular, an automatic perturbation builder based on a graph matching algorithm is developed, that is able to identify the maximum common substructure of two molecules and provide the perturbation topologies suitable for free-energy calculations using GROMOS and GROMACS simulation packages. Moreover, it was used to calculate the changes in free energy of a set of post-translational modifications and analyze their convergence behavior. Different methods were tested, which showed that MBAR and extended thermodynamic integration (TI) in combination with MBAR show better performance as compared to BAR, extended TI with linear interpolation and plain TI. Also, a number of error estimators were explored and how they relate to the true error, estimated as the difference in free energy from an extensive set of simulation data. This analysis shows that most of the estimators provide only a qualitative agreement to the true error, with little quantitative predictive power. This notwithstanding, the preformed analyses provided insight into the convergence of free-energy calculations, which allowed for development of an iterative update scheme for perturbation simulations that aims at minimizing the simulation time to reach the convergence, i.e., optimizing the efficiency. Importantly, this toolkit is made available online as an open-source python package (https://github.com/drazen-petrov/SMArt).

Introduction. Arterial hypertension (AH) is a syndrome accompanied by an increase in systolic blood pressure (BP)140 mmHg and/or diastolic BP90 mmHg. It is a progressive pathology that affects the adult employable population and leads to the development of deadly complications.
Aim. To compare the level of physicians knowledge in AHs definition, diagnosis and treatment in different centers of Russia.
Materials and methods. In the framework of the multicenter study PHYSTARH (the full name of the project Physicians and undergraduates knowledge in arterial hypertension treatment), which was launched in 2017, an anonymous survey was conducted among 425 doctors from 9 cities/regions of Russia (Belgorod Region, Moscow, Krasnodar Territory, the Republic of Adygea, Voronezh, Primorye Territory, Tatarstan, Lipetsk, Chelyabinsk).
Results. The study revealed an insufficient level of doctors knowledge in diagnosis and treatment of AH. Less than half of the respondents correctly answered the following questions: determining hypertension by the level of home monitoring of BP (36% of physicians), determining the degree of hypertension for the proposed numerical values (37% of physicians), definition and prevalence of the refractory hypertension (33% of physicians), definition of the masked hypertension (45% of physicians), the need for drug correction of high normal BP (9% of physicians), selection of the main classes of antihypertensive drugs without clinical situations (26% of physicians).
Conclusion. The physicians knowledge on AH is unsatisfactory, despite the prevalence of pathology and the availability of clinical guidelines, which, in our view, justifies the need for additional public education programs for doctors in different regions.
Firms’ Co-Creation and Innovation by Toolkits Usage: The Mediating Role of Relationship Quality
Authors:   University of Malaya, Malaysia
Published: April 2021

In the modern business world, firms gain enormous success in innovation by involving customers in the innovation process. This approach ostensibly reduces firms’ cost by decreasing reliance on internal research and development. Organizations often use knowledge from customers via toolkits usage to fulfill customer’s need. Fulfilling customer needs through customer involvement in product innovation process via toolkits usage has seen favorable outcomes for the organizations. Therefore, the purpose of this research is to examine the impact of toolkits usage on co-creation and innovation, respectively. Additionally, this study aims investigate the mediating role of relationship quality between predictor and criterion variables. This study includes a survey of 393 manufacturing firms in Malaysia. Results confirm that toolkits usage is positively associated with innovation and relationship quality. Further, the results provide evidence that relationship quality plays a mediating role on the relationship between toolkits usage and criterion variables. The results assert important implications for practitioners wanting to reap benefits from individualized products through toolkits usage. In sum, manufacturers can garner value from toolkits usage within the context of an emerging economy, like Malaysia.

Movilidad migratoria y tráfico de drogas. Exclusión y pobreza como espacios de convergencia
Authors: Urbano Reyes Javier
Published: April 2021

El presente artículo tiene como objetivo identificar aquellos procesos que convergen como raíces comunes en la interacción y el fortalecimiento del narcotráfico y la movilidad migratoria. Estos dos asuntos no nacen en épocas contemporáneas, pero sí adquieren las características y el impacto socioeconómico en el sistema de naciones a la par de la reafirmación de las consecuencias del modelo económico vigente. Se pretende, por boca de sus afectados directos, reconocer el impacto de estos dos fenómenos en el debilitamiento del tejido social a la par de la consolidación de actores paralelos al Estado, quienes en buena medida se constituyen en competidores sociales de la política pública estatal, de ahí la necesidad de proponer estrategias de gestión de estas dos problemáticas desde una perspectiva integral, bajo la premisa de que la atención de un asunto debe correr paralelamente con la gestión del otro, como fenómenos sinérgicos y no disociados. A tales efectos, se ha partido de un análisis cualitativo basado en la búsqueda de fuentes documentales y estadísticas sobre movilidad migratoria y pobreza entre otros, a la par de la organización y sistematización de testimonios de vida, que dan sustento y un papel relevante a la experiencia de los actores.

Pyrolysis is the one solution to recycle hydrocarbon-based waste material such as used lubricant and cooking oil. The aim of this research was to determine the effect of temperature and sample ratio on the liquid yields of a mixture of used lubricant and cooking oil. The semi batch reactor was used with a constant nitrogen flow rate of 5 mL/min. Three different ratios of sample mixture were applied in this experiment: 0.5:1, 1:1, and 1.5:1, and three different temperatures: 4000C, 4500C, and 5000C. The thermal pyrolysis of a mixture of used lubricant and cooking oil was deemed as the most effective pyrolysis to produce liquid fraction was obtained from reaction condition with the sample mixture ratio of 0.5:1 at 5000C. At this reaction condition, the liquid yield was 58.90% which consist of 64.12% were C1-C3 and 29.54% were C5-C15.  Liquid fraction is predicted to increase as the temperature increase and the ratio of used lubricant to cooking oil decrease. When the ratio is increased , more gas fraction is produced.

Alzheimer’s Disease among American Minority Populations: An Ecological Exploratory Study
Authors: Laquaglia Maria , Souza Marina Celly Martins Ribeiro de , Borges Carolina Marques
Published: April 2021

A significant public health concern with regards to increasing rates of Alzheimer’s is that it disproportionately affects minority groups in the United States. The present ecological exploratory study uses secondary aggregate data from the fifty United States in the year of 2019. The purpose of this study was to address the disparities in Alzheimer’s in minority populations in the US and explore associated factors. The “minority” populations considered were African American and Hispanic populations, and the “majority” population was referred to as “white”. The data were extracted from the United States Census Bureau, the CDC National Center for Health Statistics, and the Behavioral Risk Factor Surveillance System (BRFSS) Dataset. The prevalence rates of Alzheimer’s disease are greatest in both older Hispanic (12.2%) and African Americans (13.8%), compared to older whites (10.3%) in the investigated time period. Our results showed that being over 65 years old (p=.009), with a below-average ($62,843) median household income (p=.024), history of stroke (p=.029), and being a part of the Hispanic population (p=.036), were significantly associated with Alzheimer’s mortality rates in the United States. By identifying disparities in access to Alzheimer’s healthcare and at-risk communities, more comprehensive intervention strategies can be developed to promote change and advocate for more Alzheimer’s education and resource allocation for minority populations.

Facial Nerve Palsy After Occipital Nerve Blocks — A Case Report
Authors: Shoaib Abdullah
Published: April 2021

The use of bupivacaine and other local anesthetics to perform peripheral nerve blocks is a mainstay in the management of refractory headaches and migraines. In this case report, a patient presented with transient facial nerve palsy shortly after receiving occipital nerve blocks for headaches.
Patient’s symptoms self-resolved, and her symptoms were thought to be due to displacement and spreading of bupivacaine to the facial nerve. The spread of bupivacaine can be facilitated by tracking across fascial planes or nerve sheaths. Similar side effects have been seen in dental anesthesia, but there has only been one other report of such a presentation associated with occipital nerve blocks, and none in pediatric patients. Physicians should be aware of this rare complication with peripheral nerve blocks.
Flame in Literary Space of A. Blok’s “Verses about the Beautiful Lady”
Authors: Spivakova Elena Michailovna
Published: April 2021

The article is a part of a lexicographical study devoted to compiling a monographic explanatory dictionary of A. Blok’s “Verses about the Beautiful Lady”. The author aims to provide a comprehensive analysis of the lexico-semantic group “Flame” in the context of A. Blok’s poem. Scientific originality of the paper involves introducing new information about A. Blok’s lexicon, which contributes to understanding his individual style. The research findings allow concluding that flame is an integrator, which organizes images system in the poem. Flame has dual nature. On the one hand, flame is closely associated with light, particularly dawn, so the lexemes “fire”, “flame”, “light” acquire similar contextual meanings: “arrival of the Beautiful Lady”, “anticipation of her arrival”, “sacral knowledge”, “force that transforms the world or a lyrical hero”, “passion”. On the other hand, flame has destructive power, and in certain contexts, the mentioned lexemes acquire negative connotations: “suffering”, “destruction”, “anxiety”, “end of the world”.
Peculiarities of Translating Youth Slang from Spanish into Russian (by the Material of the Modern Spanish Serials)
Authors: Grunina Yulia Aleksandrovna , Terentieva Ekaterina Dmitrievna
Published: April 2021

The paper aims to identify the most efficient techniques to translate youth slang from Spanish into Russian. The article focuses on the sociocultural aspect as an essential element of scientific and translation activity. Scientific originality of the study lies in the fact that the authors for the first time analyse techniques to translate the Spanish youth slang by the material of two modern Spanish serials. The subtitled version and dubbed versions served as material for the analysis, authorial translation is proposed. The following conclusions are justified: calque translation and transliteration hinder understanding of the Spanish youth slang, so these lexical units are often translated by means of lexico-grammatical transformations.

Published: April 2021

The study aims to identify features of terms-neologisms belonging to the field of trading. Scientific novelty of the study lies in the fact that it is the first attempt at carrying out a comprehensive analysis of the English neologisms of the trading sublanguage. As a result, it is proved that the main source for the English trading neologisms is common literary vocabulary at its current development stage; there is a tendency to use abbreviations for nomination of new words and notions; compound terminological combinations dwindle and lose their relevance; computer technologies have a growing influence on formation of the considered sublanguage nomenclature.
Lexical Means to Express Temporality in P. Krusanov’s Novel “Bite of an Angel”
Authors: Sheyko Elena Vladimirovna , Markova Violetta Vladimirovna
Published: April 2021

The paper aims to identify lexical means of temporality representation in P. Krusanov’s novel “Bite of an Angel”, which belongs to the “alternative reality” genre and is characterized by the use of non-standard means to express spatial-temporal relations. Scientific originality of the study lies in the fact that the researchers describe the lexical means (temporal nominators and temporal indicators) representing the novel’s unique temporality, reveal specificity of alternative reality formation. A textual analysis allows concluding that the writer, describing different historical epochs, skilfully uses lexical units - temporal nominators and indicators - and thus creates his own imaginary world that captures readers’ attention.

Objective: To describe the identification of drugs with similar primary packaging available in a large teaching hospital. Methods: This is a descriptive study carried out using a multi-step approach. First, the small volume parenteral drugs and oral solutions available at the institution (Step I) were listed. Then, from the list developed in Step I, groups of drugs with similar packaging (double, trio or foursome) were identified according to their characteristics (Step II). These groups were then visually evaluated by the pharmacy team (Step III), and later by the internal community of the institution (Step IV). Results: A total of 233 drugs in the pharmaceutical forms of interest were available at the institution (Stage I). In step II, 62 groups with similar primary packaging were identified. After evaluation by the pharmacy team, 19 groups remained (Stage III), which were then evaluated by the internal community, generating a final list of 15 groups of drugs with similar primary packaging. Among these, the pharmaceutical form of  parenteral use (80%) and the amber ampoule as primary packaging (46.7%) were frequent. Conclusion: The results of the study point to the applicability and adequacy of the multistep approach to identify the presence of groups of drugs with similar primary packaging in a real-world scenario. The identification of these groups of drugs in health care institutions is the first important step to plan strategies to minimize errors involving similar packaging, thus increasing the safety of medication use in the hospital environment.
Swedish conditions? Characteristics of locations the Swedish police label as vulnerable
Authors: Gerell Manne , Puur Mia , Guldåker Nicklas
Published: April 2021

Deprived neighborhoods where criminal networks have a negative impact on local residents are in Sweden labeled as vulnerable neighborhoods by the police. The method used by the police to classify such neighborhoods is largely based on police perceptions, which raises issues around subjectivity and potential biases. The present study explores the characteristics of such neighborhoods based on registry data over sociodemographics and crime. The data used is a grid (N=116 660) of 250x250 meter vector grids with data on population, foreign background, employment, age characteristics, household types and eight types of crime. Generalized mixed effect models of vector grids nested in municipalities were fitted to analyze the characteristics of vector grids classified as vulnerable (N=1678). Several variables are significantly associated with a vector grid being classified as vulnerable, with the share of population that is foreign born and share with parents foreign born being the strongest predictors. In addition, we consider whether there are systematic differences between municipalities, and develop a model based on regression coefficients to predict whether a vector grid is vulnerable or not. The model re-classifies 39.8% of the vector grids, identifying locations that statistically resemble vulnerable neighborhoods but are not classified as such and vice versa.

1977. The women’s liberation movement had been in full-force for over a decade. Roots is on television and Star Wars (the real first movie, not episode one!) hits the big screen for the first time. Approximately 20 million women are in the full-time workforce – making about 59 cents for every dollar brought home by their male counterparts (U.S. Women's Bureau and the National Committee on Pay Equity) and abortion rights are on the front page when the Supreme Court rules that states are not required to use Medicaid funds to cover elective abortions. The number of doctorates in psychology is rising but women make up just about 25% of those earning PhDs overall and about 18% of those earning PhDs in science and engineering (National Science Foundation Division of Science Resources Statistics, 2006). In 1973, APA’s Division 35, the Society for the Psychology of Women, is formed and in 1975 the journal Sex Roles in founded. It is against this backdrop that the Women’s Issues in Behavior Therapy Special Interest Group (Women’s SIG) is formed by co-founders Dr. Marsha Linehan and Dr. Stephanie Stolz.

Plant Experience Questionnaire (Rioux & Wertz 2021)
Authors: rioux camille , Wertz Annie E.
Published: April 2021

A growing body of research investigating plant-related cognition and behaviors demonstrates that plants have shaped human minds and societies and that pursuing empirical research in this area can yield new insights into many aspects of human cognition and development, including food learning, danger avoidance, and cultural transmission. This research would greatly benefit from a validated measure that assesses experience with plants early in life. Here we present the validation of a new measure to assess such experience: The Plant Experience Questionnaire (PEQ), filling a major gap in the literature on plant-related cognition in infancy and early childhood. The PEQ was tested on a sample of 576 caregivers who completed the questionnaire about their child (age = 5-81 months). Factorial analysis revealed a four-dimensional structure of the questionnaire: (1) experience with indoor plants, (2) experience with outdoor plants, (3) eating from plants, and (4) parental prohibition from touching plants. The PEQ displayed good psychometric properties as shown with satisfactory internal consistency and convergent and discriminant validity and is suitable for a broad age range from infancy to early childhood. Therefore, the PEQ is an efficient and valuable tool for assessing plant experience in early life via parental report.

Published: April 2021

Objectives: Compassion is a key component of quality care. Therefore, encouraging health professionals (HCPs) to develop a patient-centred care relationship through mindfulness and compassion training may be beneficial for both patients and HCPs. We aimed at assessing the impact of a compassion-centred mindfulness program (i.e., the Mindfulness Based (MB) CARE programme) on healthcare practice. We hypothesised this training could improve patient–health professionals relationships and perceived quality of life at work of HCPs. Methods: We conducted a qualitative study including 10 phone interviews designed to explore the perceived psychological consequences of such training programme amongst HCPs who experienced the MB CARE programme at APHP Sorbonne University or during a private course. Interviews were conducted between May and July 2020. Results: Content analysis results showed that the training had an overall positive impact on the HCPs ability to feel compassion toward their patients and themselves. The HCPs were more attentive to their patient’s needs and theirs, without being able to articulate how well they were paying attention to them. The programme also helped them develop kindness towards themselves and their patients. Participants were better able to accept the difficult experiences they might encounter in the workplace or those their patients experienced, with more perceived equanimity and less reactivity.Conclusions: We conclude that professional mindfulness and compassion training programmes could be operational levers for institutions aiming at fostering a more compassionate health professionals–patient relationship, through improvement of perceived quality of life at work, more focused attention and better management of emotions.

This study presents a thematic analysis of socialization messages about race and racism in White parents' reports of their discussions with adolescents about current events involving racism (e.g., police brutality toward Black Americans). Two samples of White parents of primarily White adolescents ages 14-17 were recruited online in September 2019 (Study 1, N = 123) and June 2020 (Study 2, N = 104). Key themes included color-conscious messages, color-blind messages, endorsing equal treatment, and references to Whiteness. Rates of discussion in 2020 (79% - 81%) were double that of 2019 (40.2% - 43.4%). However, color-conscious messages were less common in 2020 compared to 2019, and references to Whiteness were rare in 2020. Color-blind messages were similarly prevalent across both studies.
Stack Overflow – Informal learning and the global expansion of professional development and opportunities in programming?
Authors: Nivala Markus , Seredko Alena , Osborne Tanya , Hillman Thomas
Published: April 2021

The purpose of this study is to examine if, and to what extent, online Community Question Answering platforms expand the opportunities for professional development in programming. Longitudinal and cross-sectional analyses of Stack Overflow Developer Surveys were used to examine users' geographical distribution, gender, experience, professional status, platform usage and education. In order to study differences between the countries with the largest number of respondents, the developer survey data was combined with indicators of human development, gender equality and educational attainment. The results show that the Stack Overflow community has expanded to some extent, both in terms of wider geographical distribution and the programming expertise of users. However, the community reflects and fails to mitigate the apparent gender disparity in the field of programming. Furthermore, participation seems to be conditioned by formal education, especially in developing countries. In general, participation patterns in Stack Overflow seem to be heavily influenced by local conditions in different countries.
How Strikes Can Arise: Sequences of Interaction in the Genesis of a Total Strike in Madrid Underground
Authors: Pohl Nicholas
Published: April 2021

Workers’ responses to austerity measures during the Great Recession were multiple and diverse. When and why they opted for contentious collective actions instead of reluctant acquiescence is still a subject of debate. In this article, I revisit the issue by examining the genesis of a total strike in Madrid Underground in June 2010, which occurred in response to a wage cut applied to this publicly owned enterprise. By drawing upon union communica-tions produced at the time of the events and semi-directive inter-views conducted with union representatives and ordinary workers, I retrace the sequences of interaction between workers, unions, the company management, and the regional government, which even-tually led to the total strike. The ﬁndings reveal that the question of ‘how’ is as important as the ‘why’: the relationship between the wage cut and the strike is in fact anything but direct. Rather, the strike resulted from a largely unintended ‘composition eﬀect’–a combination of nested interactions between multiple and inter-dependent players.
Good Politicians: Experimental Evidence on Motivations for Political Candidacy and Government Performance
Authors: Gulzar Saad , Khan Muhammad Yasir
Published: April 2021

How can we motivate good politicians – those that will carry out policy that is responsive to citizens’ preferences – to enter politics? In a field experiment in Pakistan, we vary how political office is portrayed to ordinary citizens. Emphasizing prosocial motives for holding political office instead of personal returns – such as the ability to help others versus enhancing one’s own respect and status – raises the likelihood that individuals run for office and that voters elect them. A year later, the treatment improves the alignment of policy with citizens’ preferences. These effects emerge only when treatments are randomly delivered in a public setting. Taken together, the results demonstrate that how politics is perceived shapes who decides to run for office, who is elected, as well the policies that democracies deliver.
Estudo do casamento entre MOSFETs implementados com geometrias de porta não convencionais em ambientes de radiações de raios X

Published: April 2021

This doctoral thesis illustrates the studies of the variability and mismatch between "N" type MOSFET devices (nMOSFETs) with hexagonal (DnM), octagonal (OnM) and rectangular (CnM) gate geometry, considering four different types of bias of these nMOSFETs during the ionizing radiation procedure X-ray: I- without electrical bias or with all terminals (source, door, drain and substrate) open (Floating); II- with electrical bias of the devices in the operating state of “on-state” or “closed-switch” (On-state); III- with bias of the devices in the condition of analogue operation or operating as an amplifier (Analog); IV- with device bias in the state-off or “open-switch” operating condition (Off-state). Considering the Floating bias, during the Xray ionizing radiation procedure, it appears that DnMs with an a angle of 90° reduce the mismatch between devices by 40.7% for the threshold voltage (VTH) and 56.8% for the subthreshold slope (SS), respectively, in comparison to the values found in the CnMs counterparts. Considering the On-state bias during the procedure of X-ray ionizing radiation, it is observed that OnMs with an a angle of 90° and a 50% “c” factor improve the matching between devices by 57.4% for VTH and 54.9% for SS compared to those found in CnM counterparts. In the Analog and Off-state bias during the X-ray ionizing radiation procedure, the DnMs and OnMs showed a better matching between devices compared to those obtained with the CnMs counterparts and with a 95% accuracy level. During the procedure of X-ray ionizing radiation in Floating mode, the maximum total ionizing dose (TID) used was in the order of up to 4.5 Mrad. In addition, during ionizing X-ray radiation procedures in On-State, Off-State and Analog modes, the maximum TIDs used were 200 krad for On-State and Analog modes and 20 krad for Off-State mode. Therefore, the Diamond and Octo layout styles can be considered as alternative layout strategies for the implementation of MOSFETs in order to enhance their tolerances to ionizing X-ray radiation, aiming at applications in integrated circuits (ICs) implemented with Complementary Metal-Oxide-Semiconductor (CMOS) manufacturing technology

Published: April 2021

Introduction: The breast's angiosarcoma is a rare entity, representing 1% of the breast's malignant neoplasms and is classified as primary and secondary; the latter is associated with radiotherapy and chronic lymphedema. Clinically both present as a voluminous and rapidly growing lesion. Surgery is the cornerstone of a treatment since it provides the most outstanding local control, whereas radiotherapy and chemotherapy have little impact on the disease. Similarly, the oncological prognosis is poor because this type of tumor has a high recurrence rate and overall, 5-year survival of only 20%.
Objective: Two cases of angiosarcoma of the breast (primary and secondary) are reported, both treated in the Breast Tumor Service and a bibliographic review of the disease is presented.
Materials and Methods: All breast cancer cases were reviewed in the Breast Tumor Service for two years.
Results: In the first clinical case, a 61-year-old patient was presented with a 5-month-old primary angiosarcoma in the right breast, treated with modified radical mastectomy. While in the second case, the clinical history of a 76-year-old woman with secondary breast angiosarcoma is related; the patient had a history of right breast cancer, treated ten years previously with conservative surgery, sentinel node and adjuvant radiotherapy. However, the woman presented local recurrence six years later, and she was operated on with a total mastectomy. Three years later, she developed an angiosarcoma in the surgical bed that warranted a wide resection of the chest wall.
Conclusion: The breast's angiosarcoma is an aggressive and rare tumor of unknown aetiology, since it has a high recurrence rate and poor survival. Its main prognostic factors are tumor volume and resection margins. Therefore, early diagnosis is essential because it allows complete resection of the lesion.
Conceptual Explorations around “Politics”
Authors: Palonen Kari
Published: April 2021

This article discusses the ways of conceptualizing politics in parliamentary debates. When the politics-vocabulary is ubiquitous in them, which kind of speech act lies in emphasizing the political aspect? Focusing on thematized uses allows us to identify conceptual revisions in the politics-vocabulary in digitalized plenary debates of the German Bundestag from 1949 to 2017. My fourfold scheme for conceptualizing politics (polity, policy, politicization, politicking) provides the analytical apparatus. The units of analysis in this study are compound words around politics written as single words, a German language specialty. Their frequency has remarkably risen in the Bundestag debates, and the search engine can easily find them. This research interest allows me to speculate with changes in the understanding and appreciation of politics in postwar (West)Germany.
The Concept of Religion in Meiji Popular Discourse
Authors: Takao Makoto Harris
Published: April 2021

This article challenges claims that the Japanese neologism shūkyō (as a translation for “religion”) lacked an established nature prior to the twentieth century and had little to do with experiences of the urban masses. It accordingly problematizes the term as a largely legal concept, highlighting historical newspapers as underutilized sources that offer insight into Meiji popular discourse and attendant conceptualizations of “religion.” This article endorses a shift in both our chronological understanding of shūkyō’s conceptual history as well as its sociocultural mobility. By expanding the milieu understood as being familiar with debates on a range of “religious” issues, this article thereby offers a counter-narrative in which regular use of shūkyō begins to clearly emerge from the mid-1880s, exponentially increasing with the following decades.
