Effect of Bonding Temperature and Interlayer(s) on Microstructure Evolution, Hardness, and Shear Properties of Diffusion Bonded Ti-6Al-4V Alloys
Authors: Raj Manil , N. V. Prasad M. J. , Narasimhan K.
Published: June 2021

The workhorse Ti-6Al-4V alloy has numerous applications under extreme conditions, and there is a necessity to produce metallic joints with the alloy for fabrication of some industrial components. In the present study, the solid-state diffusion bonding (DB) process was used to produce similar metal joints between Ti-6Al-4V alloy sheets with and without copper and nickel interlayers. The effect of the bonding temperature as well as the influence of interlayers on the joint interface microstructure and, subsequently, on the mechanical performance of the bonded joints were investigated. The DB was performed at three different bonding temperatures of 1,023, 1,123, and 1,223 K under high-vacuum conditions using a thermomechanical deformation simulator. The microstructure across interface of the joint was examined using optical and scanning electron microscopes. The joint strength was evaluated using both the nanoindentation technique and the shear test. The findings show the formation of intermetallic phases between titanium and interlayer(s) elements across the interface up to the bonding temperature of 1,123 K. Further increase in the bonding temperature led to a complete diffusion of the interlayers into the base metals, thereby forming the Widmanstätten microstructure across the interface. In the case of direct DB, there was a gradual closure of voids along with a homogenized joint interface with an increase in the bonding temperature. The variation of hardness across the bonding interface and the shear properties were found to be consistent with the resultant microstructural features evolved with the bonding temperature and type of interlayer(s).
Charismatic Leadership in the Catholic Church
Authors:   St. Tikhon's Orthodox University, Borsch Irina
Published: June 2021

The article analyzes the ideas of charismatic leadership developed in the Catholic Church in the second half of the 20th century. These ideas are connected, on the one hand, with the biblical revival, with the attempts to rediscover the heritage of the Church of the first centuries, and on the other hand, with new social phenomena, which are typical for the era after the Second World War. The social dimension of charisma and its role in the creation of associations were rediscovered in Catholicism during the Second Vatican Council. At the same time, a huge number of new social and evangelical initiatives appealing to charisma appeared. The new church movements became the most prominent and well-known examples of catholic “charismatic associations”. The author shows how the Catholic hierarchy managed to streamline and incorporate the charismatic leadership of lay associations into the reality of the universal church structure. The article emphasizes that the concept of charismatic leadership in the Church is in the process of evolution. The author concludes that the documents of church governance, proclaiming the absence of a conflict between charisma and institution in theory, reflect the political processes of the contemporary Catholic era: the emergence of Catholic movements with a predominant role of laity, the change of generations of Catholic elites and the formation of a new balance of responsibility between movements and the church hierarchy.
Higher Education Regionalism in Europe: from Bologna Process to Sorbonne
Authors:   Ural Federal University named after the First President of Russia B. N. Eltsin, Leskina Natalia
Published: June 2021

In 2017, the launch of Sorbonne process aimed at the creation of European Education Area by 2025 in parallel to the Bologna process existing since 1999 led to the emergence of two regional initiatives sharing mandate and membership. This study presents new empirical and conceptual insights into the ways in which a higher education regionalism can emerge and nest within another one as well as and their interplay. To this end, the paper compares the constellation of actors, competences, membership and driving forces of the two overlapping projects in higher education. It investigates plausible impact of the changes in European educational integration on Russia as a participant of the Bologna process. The results suggest that while the intergovernmental Bologna process was launched in the context of EU enlargement and embodied Pan-European vision, the EU-coordinated Sorbonne process was brought forth in the wake of multiple crises in the EU. It prioritizes the deepening of integration among a delineated group of EU members and candidates. Hence, the European regionalism in higher education is structured in concentric circles: the inner core of EU countries pursuing deeper integration and an outer circle comprising the rest of the Bologna countries, representing a geopolitical dimension for the core. The emergence of the inner core might lead to the shift in Bologna rationale towards diffusion of EU norms among countries of the outer circle. Although Russia find itself in the outer circle, there a low probability of substantial negative changes in the conditions of its participation in EU programmes, because some restrictive measures are already in force since 2014 and their expansion is unlikely due to the „selective engagement‟ in cooperation between the EU and Russia.

Published: June 2021

Objective: to analyze the association between good obstetric practices and types of delivery. Methods: a cross-sectional study, carried out with 207 pregnant women admitted to two reference maternity hospitals, whose data were collected through a questionnaire and chart analysis and analyzed by Pearson’s chi-square test. Results: it was observed that the parturients with vaginal delivery were oriented about relaxation techniques and non-pharmacological measures for pain relief, encouraged not to remain in bed and to use the Swiss ball. In contrast, women who underwent a cesarean section reported not receiving such interventions. The use of squatting exercises, massages, hot baths and encouragement not to wander were mentioned less frequently by the participants, regardless of the route of delivery. Conclusion: it was observed that good obstetric practices were associated with the normal delivery route, while in cesarean delivery, such practices were implemented less frequently.

Objective: to apprehend patients’ perception of spirituality, religiosity, and the practice of euphemia throughout hospitalization. Methods: qualitative research, conducted with 12 hospitalized patients. Data collection took place through individual interviews. The speeches were transcribed in full, submitted to thematic content analysis, and the discussion was based on the Transpersonal Care theory. Results: from the speeches, three categories emerged: Spirituality and religiosity: meaning and balm to human life; Benefits of the practice of euphemia in the hospital environment; Spirituality, religiosity, and euphemia in the art of nursing care: biopsychosocial triad in the patient’s perception. Conclusion: spirituality, religiosity, and euphemia were configured as a biopsychosocial triad capable of attributing meaning, foundation, and balm to human life. Also, it may encourage patients and nursing professionals to face the adversities of the hospital environment.

Introduction Patient safety in the operating theatre depends on the multi-track activities of the entire medical team. Guaranteeing total patient safety will allow the patient to meet his expectations, will be a source of satisfaction for the whole team, which provides care and treatment, and helps avoid legal consequences. Aim The aim of the study was to investigate which factors, according to the operating team, guarantee patient safety in the time period from the admission to the operating theatre until the transfer to the specialist ward. Material and methods The diagnostic survey method and analysis of literature were used. A propriety questionnaire created by the authors was used in order to verify the hypotheses. Results and Conclusions There were no significant correlations between age, level of education and length of service and the assessment of the impact of other activities on patient’s safety in the operating theatre. Gender and workplace did not significantly influence the evaluation of the significance of other analysed factors. The profession did not significantly differ in the evaluation of the analysed factors for the patient safety in an operating theatre. Compliance with standards and procedures before, during and after the procedure guarantees patient safety in the operating theater to a large extent in the respondents’ opinion.

Published: June 2021

The Neotropical free-living freshwater cyclopoid copepod Mesocyclops paranaensis Dussart & Frutos, 1986 was found in a small temporal pond in La Guajira, northern Colombia. Hitherto, it has been reported from Argentina, Paraguay, and Brazil. This is the first record of this species in Colombia, its northernmost finding in South America, and the fourth locality in which this species has been recorded from. Mesocyclops paranaensis can be distinguished from its closest congeners by a unique combination of the characters of the female, including: 1) leg 4 intercoxal sclerite with two large, acute projections; 2) P3, P4 intercoxal sclerite caudal surface lightly pilose; 3) seminal receptacle with narrow lateral arms and weakly convex anterior margin; 4) second antennary endopodite with seven setae, and insertion of antennary exopodal seta with adjacent spinules; 5)frontal surface of P1 basipodite ornamented with long spinules; 6) posterior margin of anal somite with continuous row of spinules; and 7) inner margin of caudal ramus hirsute. The Colombian population shows some subtle morphological differences with respect to previous reports.
Word Portfolio Optimization in the Environment of Zero Interest Rate
Authors: Demcenko Darja
Published: June 2021

This paper provides a deep analysis of ten globally diversified portfolios, composed of different financial instruments: bonds, shares, ETF’s, commodities, indexes, currencies, constructed applying various optimization techniques.  Statistical moments, such as mean, standard deviation, kurtosis and skewness of portfolios are compared and discussed. Moreover, performance of the portfolios within the time horizon of one year estimating Sharpe ratio, Treynor ratio, Sortino ratio is presented. Furthermore, a risk analysis of created portfolios is evaluated in terms of historical VaR and CVaR applying confidence interval 95%. The main results of this paper reveal that the portfolio, which is optimized to minimize VaR produces high expected shortfall. Secondly, the Risk Parity portfolio, despite reducing volatility, has delivered the highest kurtosis of the return, which may indicate the possible tail loss. Furthermore, the maximum Sharpe ratio portfolio has delivered extremely high kurtosis in comparison with the kurtosis of the other portfolios. Finally, it is observed that for the Naïve diversification portfolio it has been typical to have the highest downside deviation.

Gender and socioeconomic inequalities in health and wellbeing across age in France and Switzerland
Authors: Barbuscia Anna , Comolli Chiara
Published: June 2021

There is increasing evidence that wellbeing is unequally distributed across sociodemographicgroups in contemporary societies. However, less is known about thedivergence across social groups of trajectories of wellbeing across age groups.This issue is of great relevance in contexts characterised by changing populationstructures and growing imbalances across and within generations, and in whichensuring that everyone has the opportunity to have a happy and healthy life courseis a primary welfare goal. In this study, we investigate wellbeing trends in Franceand Switzerland across age, gender, and socioeconomic status groups. We use twohousehold surveys (the Sant´e et Itin´eraires Professionnels and the Swiss HouseholdPanel) to compare the unfolding inequalities in health and wellbeing across agegroups in two rich countries. We view wellbeing as multidimensional, followingthe literature highlighting the importance of considering different dimensions andmeasures of wellbeing. Thus, we investigate a number of outcomes, includingdifferent measures of physical and mental health, as well as of relational wellbeing,using a linear regression model and a linear probability model. Our findings showinteresting country and dimension-specific heterogeneities in the development ofhealth and wellbeing over age. While our results indicate that there are gender andeducational inequalities in both Switzerland and France, and that gender inequalitiesin mental health accumulate with age in both countries, we also find that educationalinequalities in health and wellbeing remain rather stable across age groups.
Anthropometric history and the measurement of wellbeing
Authors: Harris Bernard
Published: June 2021

It has often been recognised that the average height of a population is influencedby the economic, social and environmental conditions in which it finds itself, andthis insight has inspired a generation of historians to use anthropometric data toinvestigate the health and wellbeing of past populations. This paper reviews someof the main developments in the field, and assesses the extent to which heightremains a viable measure of historical wellbeing. It explores a number of differentissues, including the nature of human growth; the impact of variations in diet andexposure to disease; the role of ethnicity; the relationships between height, mortalityand labour productivity; and the “social value” of human stature. It concludes that,despite certain caveats, height has retained its capacity to act as a “mirror” of theconditions of past societies, and of the wellbeing of their members.
Serological survey of Coxiella burnetii infections in dairy cattle, sheep, goats and zoo animals in Hungary – Short communication
Authors: Dobos Attila , Fodor István , Kiss Gerda , Gyuranecz Miklós
Published: June 2021

Q fever is a disease of high zoonotic potential, but interest in its causative agent is rather low although it causes some public health problems in Hungary. The prevalence of Q fever is highly variable by country. The main reservoirs of the disease are the same domestic ruminant species everywhere, but the epidemiological profile depends on the features of the specific reservoir. The aim of this large-scale study was to demonstrate the importance of Q fever in different species as a possible source for human infection in most regions of Hungary. A total of 851 serum samples from 44 dairy farms, 16 sheep flocks, 4 goat farms and 3 zoos located in different parts of Hungary were tested. The presence of antibodies to Coxiella burnetii was surveyed in dairy cattle (n = 547), goats (n = 71), sheep (n = 200) and zoo animals (n = 33). The animal species tested in Hungary showed different seroprevalence values of C. burnetii infection. Seropositivity by the enzyme-linked immunosorbent assay was found in 258 out of 547 (47.2%) cows and in 69 out of 271 (25.5%) small ruminants, among them in 47 out of 200 (23.5%) sheep and in 22 out of 71 (31.0%) goats. Antibodies to C. burnetii were not detected in zoo animals. Seropositivity was demonstrated in 44 out of 44 (100%) dairy cattle farms, with at least one serum sample found to be positive on each farm. The seropositivity rate of small ruminant farms was 55.0% (11 positive out of 20 tested), with 9 out of 16 (56.3%) sheep flocks and 2 out of 4 (50.0%) goat herds showing seropositivity.

The purpose of this study was to determine how big the role of the image of halal tourist destinations on visiting interest is influenced by market potential, electronic word of mouth (E-WOM), and social media. The research method uses quantitative methods, with data processing using SEM-PLS (Partial Least Square). The results showed that the role of halal tourist destinations on visiting interest has a big influence. The image of halal tourist destinations will not develop properly if it is not supported by E-WOM, social media, and market potential, which are carried out continuously. Therefore, good cooperation between the local government, the community and all related parties are required to increase halal tourism.

The coronavirus pandemic that hit the world in early 2020 has weakened Europe very severely. In the first period (January-February), the disease was often neglected, which allowed it to spread rapidly. In March, panic struck European societies, the health systems of many countries collapsed, and governments introduced drastic restrictions on civil liberties and on the functioning of the economy. The European Union, which was helpless in the first period, took steps in the spring to restore the European economy after the end of the epidemic.

Published: June 2021

On 11th March 2020, the World Health Organization (WHO) announced the COVID-19 pandemic, i.e., SARS-CoV-2 coronavirus disease. A few days later, an epidemic emergency was announced in Poland. From the very beginning, it was obvious that the pandemic, apart from the strictly health dimension, would affect a number of aspects of the state's functioning, including the key one – its economy. The purpose of the article is to provide a multidimensional analysis of the impact of the pandemic on the state’s financial status, in particular in relation to the most fundamental economic and social indicators as well as formal and legal solutions, including so-called “anti-crisis shields” (1.0 – 4.0). Finally, analysis of the social perception of the phenomenon (public opinion) in relation to two groups, i.e., entrepreneurs and the general public, also constitutes one of the key elements of the present study.

The aim of the study is to show the mutual relations between the government administration and local government units in the conditions of the COVID-19 pandemic. The article uses the decision-making method in order to analyse the actions taken and the decision-making process. Discourse analysis is used to study the communication process between the government administration and local government administration. To analyse the legal acts adopted during the pandemic, an institutional and legal analysis was used. New, serious challenges related to the COVID-19 pandemic did not change the difficult, tense relations between the local government and the central administration, nor did they weaken the conflict between them. In the period of the epidemic, the current animosities, which had existed even before its outbreak, were reinforced. They were related to the dispute between the omnipotence of the state and decentralist tendencies. Additionally, new discrepancies, resulting from the consequences of the epidemic and radical actions taken in relation to it, arose.

In recent months, the COVID-19 virus has become a key challenge for all countries, regardless of their geographical location, economic situation or system of government. As stated by Grzegorz Rydlewski, the crisis has become a condition for balancing and targeting the activities of supranational structures, states, various intermediate structures, and individual people (Rydlewski, 2020). The main aim of the present article is to discuss the trends and changes to public decision-making processes introduced by the lawmaker in connection with the epidemic threat to local government administration. Unquestionably, one of the negative effects of the pandemic is the fact that holding meetings of local government bodies in physical form has been unsafe since the outbreak. Legal and technical solutions have been introduced which partly transfer the decision-making process to the digital world by allowing remote meetings for a wide range of statutory bodies. In this context, it is important to examine the usefulness, practicality and efficiency of the solutions adopted, and also to identify key obstacles and challenges to local government decision-making processes. Additionally, examples of ICT tools supporting decision making in local government units will be duly provided. Finally, key problems identified in the course of the analysis in question, e.g., issues related to the area of cyber security, will be also highlighted.

Published: June 2021

Soy germ is one of the richest phytoestrogen sources and thus has many benefits for health such as improving bone density, cardiovascular health, cancer prevention, and menopausal treatment. In addition, phytoestrogens are reported to act as antioxidants, removing reactive oxygen species and thereby preventing oxidative damage in living tissue. Phytoestrogens in soy germ include isoflavone compounds and their derivatives: daidzein, genistein, glycitein, daidzin, genistin, glycitin, acetyl daidzin, acetyl genistin, acetyl glycitin, malonyl daidzin, malonyl genistin, malonyl glycitin. Isoflavones aglycone forms comprise only about 2-5% of total isoflavones, however, they express more biological effects than the others. The objective of this study was to compare the antioxidant activity among three extracts: purified isoflavone aglycone extract, crude isoflavone aglycone extract and total phytoestrogen extract. The IC50 value of DPPH free radical scavenging capacity of purified isoflavone aglycone extract, crude isoflavone aglycone extract and total phytoestrogen extract were 0.763 ± 0.016; 3.345 ± 0.076; 6.142 ± 0.050 mg/ml, respectively. The IC50 value of reducing power activity of purified isoflavone aglycone extract, crude isoflavone aglycone extract and total phytoestrogen extract were 1.248 ± 0.024; 3.961 ± 0.172; 9.385 ± 0.272 (mg/ml). As our result, the ranking order of the antioxidant activity (from highest to lowest level) was purified isoflavone aglycone extract > crude isoflavone aglycone extract > total phytoestrogens extract.

Published: June 2021

Electrochemical activated solution possesses a wide variety of antimicrobial activities. Electrochemical activated solution (EAS) has been known as a super disinfectant solution with the promote ability in killing most of bacteria and fungi and safe for human use. Therefore, it has been studied and used in many different areas of life such as medication, food processing industry, etc., However, there are few reported the effect of EAS in agriculture. This study was conducted to determine the effects of using EAS to treat broccoli seeds on seed germination rate and growth of sprouts. The EAS was generated from KCl solution, the EAS was diluted with distilled water at 1.0, 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2 and 0.1 strengths of the source EAS. The results showed that treating seeds with EAS could reduce the quantity of microorganism on the surface of broccoli seeds, without affecting seed germination rate and sprout growth. The 0.3 strength EAS (pH 6,7; oxidants concentration of 8,6 ppm; ORP 560 mV) was the most suitable solution for microorganism killing on broccoli seeds.
DEVELOPING AND VALIDATING A GT-SUITE BASED MODEL FOR A SECOND GENERATION COMMONRAIL SOLENOID INJECTOR

Published: June 2021

Injection profiles, containing important parameters like injection rate, directly affect the spray structure, fuel-air mixture quality, and as such the physical and chemical processes occurring in the IC engine’s combustion chamber. Therefore, injection profiles are one of the keys to improving power, thermal efficiency and minimizing the emission for IC engines. In this paper, a GT-Suite - based simulation model for a second generation solenoid commonrail injector typically utilized in Hyundai 2.5 TCI-A diesel engines, has been successfully developed and validated. The validation is done by using experimental data are acquired by a Zeuch’s method-based Injection Analyzer (UniPg STS) in University of Perugia, Italy. The calibration data is measured over a wide range of rail pressure and energizing time (ET) corresponding to the engine operating conditions. The results show that the injector model developed here is reliable and suitable for examining the injector’s hydraulic characteristics. The difference in start of injection values obtained through experiment and simulation is only about 15 µs. The total injection volumes obtained through experiment and simulation under ET > 0.8 ms is less than     10 % while the difference is quite high under ET < 0.8 ms and high rail pressure (up to 34.5 %).

Published: June 2021

This paper describes an algorithm for constructing a surface based on the projection of a triangular mesh applied to this surface. In this case, the angles of the mesh triangles are assumed to be known. This algorithm can be applied to determining the orientation of a three-dimensional object from its snapshot, if the object surface has triangular elements with known angles in advance. In addition to the description of the algorithm, the article gives examples of surface restoration (see figures 2–4), calculates the calculation error for them and examples of the algorithm application in the problem of determining the orientation of buildings from a photograph. As a result, a spatial triangular mesh was reconstructed from a given flat grid (see figure ref fig: fig1), and the calculation error was 6.21e-05. Measurements of the coordinates of a point in the images and calculations using the formulas (2) and (3) gave an error on average of 0.84°.

ABSTRACT Background: Epilepsy affects about 50 million people worldwide and around 30% of these patients have refractory epilepsy, with potential consequences regarding quality of life, morbidity and premature mortality. Objective: The aim of treatment with antiseizure medications (ASMs) is to allow patients to remain without seizures, with good tolerability. Levetiracetam is a broad-spectrum ASM with a unique mechanism of action that differs it from other ASMs. It has been shown to be effective and safe for treating adults and children with epilepsy. Methods: This was a phase III, multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of levetiracetam in children and adults (4-65 years) as an adjuvant treatment for focal-onset seizures. It was conducted among 114 patients undergoing treatment with up to three ASMs. The primary efficacy analysis was based on the proportion of patients who achieved a reduction of ≥ 50% in the mean number of focal seizures per week, over a 16-week treatment period. The patients were randomized to receive placebo or levetiracetam, titrated every two weeks from 20 mg/kg/day or 1,000 mg/day up to 60 mg/kg/day or 3,000 mg/day. Results: Levetiracetam was significantly superior to placebo (p = 0.0031); 38.7% of the participants in the levetiracetam group and 14.3% in the control group shows reductions in focal seizures. Levetiracetam was seen to have a favorable safety profile and an adverse event rate similar to that of placebo. Conclusion: Corroborating the results in the literature, levetiracetam was shown to be effective and safe for children and adults with refractory focal-onset epilepsy.

ABSTRACT Background: During the moderate stage of dementia due to Alzheimer’s disease (AD), language disorder is more evident and it impacts on communication. An overview of language impairment could be helpful to find compensatory communication strategies for these patients. Objective: To identify all language impairments among patients with moderate-stage of AD. Methods: 20 patients diagnosed with probable AD based on the criteria of the NINCDS-ARDRA, with a MMSE score of 13-23 points and CDR=2, who were undergoing treatment for AD with therapeutic doses of acetyl cholinesterase inhibitors, were assessed using the Boston Diagnostic Aphasia Examination (BDAE), a test that provides a broad assessment of language. The results were compared with the performance of a normal population. Results: The patients assessed in this study presented normal scores for oral and written word recognition, repetition, mechanics of writing, primer-level dictation and spelling to dictation but also had impairment at most levels of linguistic processing, in oral and written comprehension and production. In general, as expected, the tasks relying on access to the mental lexicon were most significantly affected. However, they performed well in the naming task, in which semantic cues were presented. Moreover, the patients assessed in this study had better performance in written comprehension tasks than in oral ones. Conclusion: The severity of the language impairments was not homogenous, with some linguistic abilities more impaired than others. The abilities that were found to be preserved can help to guide strategies for aiding in communication at this stage of AD.
Caligula: a neuropsychiatric explanation of his madness
Authors: CHARRY-SÁNCHEZ Jesús David , VELEZ-VAN-MEERBEKE Alberto , PALACIOS-SÁNCHEZ Leonardo
Published: June 2021

ABSTRACT Gaius Julius Caesar Augustus Germanicus, better known as Caligula, (12 CE to 41 CE) was the third Roman emperor and ruled only four years. Throughout his life he experienced several traumatic events, and, in addition, historians mention some premorbid conditions that could cause him to become the monster that most historians know today. When Caligula was 25 years old, he suffered a near-fatal illness that turned his story around. One possible cause was lead poisoning due to the high consumption of wine, which contained lead, by Roman patricians. On the other hand, it is plausible that Caligula experienced epilepsy that began in childhood, later experienced status epilepticus in 37 CE, which triggered an epileptic psychosis with the consequent psychopathic and paranoid changes that led him to the madness noted by historians.
IS ACCOUNTING ALCHEMY STILL THE RIGHT MEDICINE FOR FIRM’S EARNINGS AND BOOK VALUE? EVIDENCE FROM SUB-SAHARAN AFRICA
Authors: OKORO EDESIRI GODSDAY , EKWUEME CHIZOBA M.
Published: June 2021

ABSTRACT Purpose: A major thread in accounting literature, which has remained a contentious issue, is how accounting alchemy can be modeled. The paper builds on existing accrual models in proposing an accounting alchemy model and tests if it is still the right medicine for earnings and book value of firms. The accounting alchemy model was based on mechanisms of earnings, book value, earnings before extraordinary items, net profit after tax, cash flow from operations, revenue, and total assets. We modified accrual models on the view that accrual models suggest that incomes/expenses are the most manipulated; contrarily, accounting alchemy proposes that assets are alchemized. Originality/value: This paper proposes a new empirical model of accounting alchemy and practically assesses the validity of the model in Sub-Saharan Africa, where there are no studies. The proposed accounting alchemy model can be used in Asia, Europe, and other parts of the world to see if the study results can be replicated. Design/methodology/approach: Ex post facto design was used, and secondary data were obtained for selected quoted firms in Sub-Saharan Africa comprising Nigeria, South Africa, and Kenya from 2012 to 2016. A sample of 64 firms was selected in the consumer and industrial goods subsector, and data were analyzed via descriptive (mean, standard deviation, correlation) and inferential (regression, fixed, and random effects) statistics. Findings: Findings indicated that earnings and book value are significantly affected by accounting alchemy. This implies that accounting alchemy is not the right medicine for firm’s earnings and book value. The result has practical application for researchers and the regulatory framework of accounting.
HIPSTERS VERSUS POSERS: FANNISH SPLIT IN THE INDIE MUSIC WORLD

Published: June 2021

ABSTRACT Purpose: Web 2.0 technologies have enhanced relational dynamics in fan communities. Indie music fans significantly identify themselves with the genre and participate in these communities within a music industry reinvention scenario. Based on the Foucauldian perspective, by sharing knowledge about media products, fans manifest truths capable of expressing subjectivities - parrhesia, a way of mutually affecting different truths. Thus, the aim of the present study is to analyze how parrhesia is operated in interactions among indie music fans. Originality/value: The present research expands an important theoretical-investigative path in the consumer culture theory (CCT) field by adopting Michel Foucault’s later theoretical cycle, which addresses the construction of subjectivities. Design/methodology/approach: Netnography of interactions among indie music fans was carried out in one of the largest online discussion forums on the topic. Findings: Heated discussions observed in the investigated community often create a split that shows a dispute focused on defining what being an indie music fan means. Based on disruptive parrhesia anchored in moral backgrounds associated with erudition and collectivism versus hedonism and individuality, self-declared true fans and those who seek fun establish alter-subjectivities as hipsters and posers.
THE ROLE OF IoT iN THE RELATIONSHIP BETWEEN STRATEGIC LOGISTICS MANAGEMENT AND OPERATIONAL PERFORMANCE
Authors: LOPES YAN M. , MOORI ROBERTO G.
Published: June 2021

ABSTRACT Purpose: Against the backdrop of the transaction costs and theoretical strands of thought in authors of the strategic logistics management (SLM), operational performance (OP), and the internet of things (IoT), the purpose of this study is to verify if the IoT performs a mediating effect on the relationship between SLM and OP. Originality/value: The bibliometric study indicated that studies on the IoT aimed at the business area are still scarce. Therefore, there is a prospect of expansion of the knowledge frontier of the administration field. This article seeks to show whether the IoT has a mediating influence on the relationship between SLM and OP, in addition to highlighting the most significant variables of each construct. This study can help business managers and researchers to identify the benefits of adopting IoT. Design/method/approach: For that, a quantitative research was carried out. The research collected data through a semi-structured questionnaire with a sample of 76 companies. Data were treated by descriptive statistics and multivariate statistics with the modeling technique in structural equations. Before the application of the modeling technique in structural equations, data were submitted to tests of convergent and discriminant validity. Findings: The IoT plays a mediating but partial role in the relationship between SLM and OP. Implementing the IoT provides better efficiency by enabling proactive decisions, interconnecting resources, automating, streamlining, remotely controlling, generating customer information, and eliminating errors.

Published: June 2021

Resumo: O artigo problematiza o currículo como espaço de poder e de produção de subjetividades comprometido com diferentes projetos de formação básica, partindo do processo de institucionalização do ensino de Espanhol na rede municipal de Niterói/RJ - situado no cerne de conflitos discursivos. Para tal, articula-se a visão discursiva de linguagem à perspectiva cartográfica, com vistas a mapear o processo de significação do ensino de uma língua estrangeira em meio a políticas linguísticas e cognitivas. As análises dedicam-se ao referencial curricular, ao livro didático e à avaliação e evidenciam um embate entre visões de (ensino de) língua, das estruturais às utilitaristas, voltadas à formação para o mercado.
