Changing Emotions in the COVID-19 Pandemic: A Four-Wave Longitudinal Study in the United States and China
Authors: Li Ying , Luan Shenghua , Hertwig Ralph
Published: October 2020

The COVID-19 pandemic has turned people’s lives upside down worldwide. Having declared the new coronavirus a public health emergency of international concern on January 30, 2020, the World Health Organization officially declared COVID-19 a pandemic on March 11, 2020 (World Health Organization, 2020a, 2020b). A full year later, the virus continued to pose a huge global risk to public health and to disrupt lives on an unprecedented scale. The impacts of the pandemic can be mitigated not only by government policies and regulations, but also by individual emotional and behavioral responses (e.g. actively avoiding social contact out of fear). By examining how people’s emotional experience changed over the first year of the pandemic, our study aims to track how the general public reacted to the emerging crisis, to evaluate the consequences of widespread negative emotions on preventive behaviors, and to provide insights into how preventive behaviors can be encouraged and maintained in the long term.

On Critical Hope and ‘Anthropos’ of the Non-Anthropocentric Discourses: Some Thoughts on Archaeology in the Anthropocene
Authors: Hacıgüzeller Piraye
Published: October 2020

In this essay I scrutinise the non-anthropocentric discourses of the Anthropocene with the ultimate aim of starting a discussion about their use in archaeology. Specifically, I stress that these discourses inherit the hope for human progress that characterises Critical Theory of the Frankfurt School, i.e. ‘critical hope’. This is a type of hope that renders the non-anthropocentric discourses of the Anthropocene self-contradictory. Even when they manage to escape the hold of critical hope, such discourses, I argue, still suffer from ethical failings due to their inherent lack of focus on human-human relations and largely ahistorical nature. I conclude the essay by advocating an Anthropocene archaeology not dominated by non-anthropocentric discourses and making a related call for a slow archaeology of the Anthropocene.
A SYSTEMATIC REVIEW OF SCIENTIFIC STUDIES ON THE EFFECTS OF MUSIC IN PEOPLE WITH OR AT RISK FOR EATING DISORDERS
Authors: Testa Francesca , Arunachalam Sarah , Heiderscheit Annie , Himmerich Hubertus
Published: October 2020

Background: The prevalence of the three main eating disorders (EDs) anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED) is increasing, and a growing number of patients with EDs is seeking professional help. Thus, there is a need for additional treatment strategies in EDs. The aim of this review was to summarize the literature on the benefits and risks of music as well as the evidence for its therapeutic application in people with EDs.Methods: Following the PRISMA guidelines, we performed a systematic literature review on scientific studies on the effect of music in people with or at risk for EDs using PubMed and the Web of Science database. The search terms used were: “music”, “music therapy”, “eating disorders”, “anorexia nervosa”, “bulimia nervosa” and “binge eating disorder”. Results: 16 out of 119 identified and screened articles qualified as scientific studies involving a total of 3,792 participants. They reported on the use of music or music therapy in individuals with or at risk of AN and BN, but not BED. In inpatients with AN, listening to classical music was beneficial to food consumption. Singing in a group reduced post-prandial anxiety in AN inpatients and outpatients. Vodcasts which also included positive visual or autobiographical stimuli helped BN patients with anxiety and body image perception. Songwriting and sessions with a Body Monochord helped with the processing of therapeutically relevant topics in AN. Watching music videos, however, reinforced body dissatisfaction, drive for thinness, bodyweight concerns, preoccupation with physical appearance in pre-teenage and teenage girls, and drive for muscularity in adolescent boys. Conclusions: These findings suggest that the therapeutic application of music may be beneficial in patients with AN and BN. However, the availability of studies with a rigorous randomized controlled trial (RCT) design is scarce.
Motivational Profiling of League of Legends Players
Authors: Brühlmann Florian , Baumgartner Philipp , Wallner Günter , Kriglstein Simone , Mekler Elisa D
Published: October 2020

Player motivation is a key research area within games research, with the aim of understanding how the motivation of players is related to their experience and behavior in the game. We present the results of a cross-sectional study with data from 750 players of League of Legends a popular Multiplayer Online Battle Arena game. Based on the motivational regulations posited by Self-Determination Theory and Latent Profile Analysis, we identify four distinct motivational profiles, which differ with regards to player experience and, to a lesser extent, in-game behavior. While the more self-determined profiles "Intrinsic'' and "Autonomous'' report mainly positive experience-related outcomes, a considerable part of the player base does not. Players of the "Amotivated'' and "External'' profile derive less enjoyment, experience more negative affect and tension, and score lower on vitality, indicating game engagement that is potentially detrimental to players' well-being. With regards to game metrics, minor differences in the rate of assists in unranked matches and performance indicators were observed between profiles. This strengthens the notion that differences in experiences are not necessarily reflected in differences in behavioral game metrics. Our findings provide insights into the interplay of player motivation, experience, and in-game behavior, contributing to a more nuanced understanding of player-computer interaction.

Survey sampling in the Global South using Facebook advertisements
Authors: Rosenzweig Leah R , Bergquist Parrish , Hoffmann Pham Katherine , Rampazzo Francesco , Mildenberger Matto
Published: October 2020

Survey research in the Global South traditionally requires large budgets and lengthy fieldwork, for which researchers hire local enumerators to conduct face-to-face surveys with respondents. However, much of the world’s population is now digitally accessible, offering an opportunity for researchers with limited budgets and those seeking to study settings where in-person contact is impossible, such as natural disasters, violent conflicts, and pandemics. In this paper, we evaluate whether Facebook advertising can be used to cost-effectively generate representative survey samples in the Global South. We introduce a framework for evaluating quality in Facebook survey samples, highlighting key trade-offs for researchers considering the platform. We then quota-sample respondents in two countries: Mexico (n=5,168) and Kenya (n=1,452) to evaluate how well these samples perform on a diverse set of survey indicators related to both internal and external validity. We find that while the Facebook platform can quickly and cheaply recruit respondents, these samples tend to be more male, more educated, and more urban than the overall national populations. Applying post-stratification weighting after oversampling key demographic variables ameliorates, but does not fully overcome, these initial sample imbalances. Our analysis demonstrates the considerable potential of Facebook advertisements to cost-effectively conduct research in diverse global settings.

Samodzielność zawodowa nauczycieli wychowania przedszkolnego i edukacji wczesnoszkolnej oraz jej uwarunkowania
Authors: Domagała Dominika
Published: October 2020

The interest in the teaching profession is evident in the discussions of students and their parents, school graduates, teachers working at various stages of education, sociologists, psychologists, educators and representatives of many other professions that are simply impossible to be mentioned. Topics of these discussions are varied, they concern teachers’ qualifications and competences, their educational background, selection of candidates for the profession, personality traits, the functions they perform, teaching methods used by them, etc. Often, the participants of such discussions are not professionally connected with the teaching profession, but each of them had the opportunity to develop their own view and opinion of this profession based on many years of experience while participating, as a student, in the process of education. It can be assumed that this attention points to the significant role of the teacher in society and therefore results in frequently emotional discussions that conclude with enumeration of the teachers’ duties, skills and abilities in addition to the principles behind their actions and conduct while performing their didactic and educational work. At this point, I would like to pose the questions: What about the teacher’s independence? Does the teacher have the opportunity to carry out his or her work independently? In the article, which consists of two parts, I attempt to answer these questions. In the first part, I present theoretical approaches to the teacher, his or her qualifications and competences, with particular focus placed on the professional independence. The second part contains the results of surveys on professional independence and its determinants, conducted among pre-school and early school education teachers in the Wielkopolska region.

LA MONTAÑA MÁGICA Y LA COVID-19. LA LITERATURA SIEMPRE
Authors:   Universidad Autónoma de Chiapas, Álvarez-Arana Silvia , Velázquez-Toledo Gabriel
Published: October 2020

The purpose of this essay is to show how the German novel The Magic Mountain (1924) by Thomas Mann captured, from different perspectives, the effects that isolation and diseases have on the human mind. The author wrote it in such a way that, even after the 100-year gap between tubercu-losis and COVID-19, the argument’s relevance and the characters’ develop-ment through their actions and emotions are a reflection of the current archetype. Thus, we can notice a parallel between the aesthetic image of the havoc in the protagonist’s psyche and the emerging conclusions about mental health during this crisis, that have been growing thus far.
Media Use, Race and the Environment: The Converging of Environmental Attitudes Based on Self-Reported News Use
Authors: Elias Troy , Hmielowski Jay
Published: October 2020

Using a purposive sample with an even distribution of 299 non-Hispanic Whites, 294 African Americans, 292 Asian Americans and 295 Hispanics, we test a moderated mediation model that examines the relationship between self-reported news media consumption (e.g., non-conservative and conservative) and environmental behavioural intentions. Our study found evidence supporting the mainstreaming hypothesis (converging attitudes) across key variables within the theory of planned behaviour (TPB). Our results also reveal non-conservative outlets to be associated with more favourable environmental attitudes, subjective norms and perceived behavioural control, while conservative outlets are associated with less favourable levels for two of these three variables. Results also indicate conditional indirect relationships between non-conservative news use on behavioural intentions through our TPB variables, which vary by race/ethnicity.

TO EVALUATE EFFECT OF HORIZONTAL HIP OFFSET AND LEG LENGTH RECONSTRUCTION ON FUNCTIONAL OUTCOME OF TOTAL HIP REPLACEMENT
Authors: Jain Harshit , Saini Hemraj
Published: October 2020

Background: For total hip replacement besides long term durability a optimal postoperative functional outcome is essential.so aim of this study was to determine the combined influence of hip geometry reconstruction on the clinical outcome following primary total hip replacement for unilateral osteoarthritis.

Methods: A hospital based prospective study was carried out on 60 cases of unilateral osteoarthritis with normal contralateral hip. We prospectively assessed the clinical outcome and radiographic parameters for hip geometry reconstruction using validated measurements for the operated hip compared to the contralateral native hip with primary unilateral THA. The correlation of reconstruction parameters was investigated using a multivariate polynomial regression model for the dependent variable ?HHS (difference between the Harris hip scores preoperatively and 6 months postoperatively). Target zones for hip reconstruction were investigated for an association with superior clinical outcome.

Results: The regression model demonstrated a significant correlation for the ?HHS and both hip offset (HO) reconstruction and leg length difference. Patients with accurate to slightly increased HO reconstruction combined with balanced leg length demonstrated a significantly higher ?HHS than patients outside this zone.

Conclusion: HO and leg length reconstruction demonstrated an additive effect on clinical outcome and surgeons should aim for high accuracy in the reconstruction of both factor.

Authors: Nayak Asmita , Saxena Ruchi , Saxena Gajendra
Published: October 2020

Background: High concentrations of maternal C-reactive protein have been associated with adverse pregnancy outcome, and premature uterine contraction may be predicted by elevated levels of C-reactive protein.

Methods: Hospital based comparative analysis was conducted on women with early pregnancy upto 14 weeks with either abdominal pain or vaginal bleeding or suspected extrauterine pregnancy. C-reactive protein (CRP) quantitative estimation is done by turbi-diametric method.

Results: The mean c-reactive protein level in cases 2.23 with min-max value ranging from 0.82-3.94 mg/dl while in controls mean c-reactive protein value came to be 9.15 with min-max range from 3.11-24.9mg/dl.

Conclusion: Our results of significantly increased CRP levels in normal pregnancy and a clear association between CRP and normal pregnancy, support the clinical application of this diagnostic tool in early pregnancy, especially as a predictor of abnormal first trimester pregnancies.

Distortion of underwater images can impair both the accuracy and robustness of 3D scene reconstruction algorithms. The problems that arise are related to the lack of robustness of these methods to changes in the underwater environment and features of transmitting and receiving signals under water, including, in particular, uneven illumination of the underwater environment, rapid attenuation, scattering and refraction of light when passing through an inhomogeneous medium of air-water-glass, limiting the frequency spectrum of passing light, which leads to the absorption of low-frequency components to a greater extent than light of higher frequencies. All this seriously complicates the ability to extract information about the scene as a whole and objects of interest located in the underwater environment, limits the use of standard image processing algorithms and requires their significant improvement. This article offers a new approach to analyzing the accuracy of constructing 3D coordinates of the working space of an underwater robot. The approach is based on underwater camera calibration, assessment of camera image centers taking into account the waterproof shell. We use statistical analysis that allows us to evaluate the impact of all sources of disturbances (both hardware and software) based only on experimental data. In particular, it shows how to get the error distribution using the measured values of the calibration sample and obtained by triangulation under underwater conditions. This makes it possible to simultaneously evaluate the systematic error and the distribution characteristics of the random component of the error in restoring 3D coordinates of the workspace. An important feature of the proposed approach is the ability to assess the impact of all sources of disturbances in the aggregate, including the design of a waterproof shell, based only on experimental data obtained in the underwater environment. In addition, the same approach can also provide estimates of the position of camera image centers, allowing for the presence of a waterproof shell to improve the accuracy of image processing algorithms. The proposed approach was tested on real data.

The accuracy of field/process reconstruction from the field/process measurement data at the nodes of the space-time lattice is the main quality criterion for the control system. Due to the unreliability of the system, information from the lattice nodes is lost, which is equivalent to its thinning. There is an analytical connection between the error in the field representation and the number of nodes operating with a known probability. Approximate formulas estimating the increment of the error in the representation of processes and fields with power-law spectra with a decrease in the number of nodes N of the space-time lattice for are proposed. Real control systems are multichannel and retain partial useful operability in the event of a failure of a certain number of channels, i.e. they are redundant. Formulas for calculating the reliability of redundant shipborne sounding and towed devices, automatic buoy stations with meters on the horizons and with distributed thermopiles are derived. Towed systems, coastal stations and autonomous buoy stations should operate as long as possible. To build durable systems, the results obtained earlier in the theory of reliability by the author on the ineffectiveness of the static reserve, the fundamental inappropriateness of external diagnostics of faults by observing the inputs and outputs of devices, the possibility of ideal diagnostics of faults by replacing from the dynamic reserve are used. This is the only known method that provides optimal and ideal diagnostics of malfunctions regardless of the structure of the systems and, therefore, allows you to build recoverable and arbitrarily durable systems. The diagnostic method by replacing from the reserve in the software implementation is extended to a set of nodes of the space-time lattice for selecting information from the environment.

Based on the archival data set of the Institute of Natural and Technical Systems from 1955 to 2015 the intra-annual variability of temperature, salinity, dissolved oxygen and PH in the surface layer of the waters of the northwestern shelf of the Black Sea, including the Danube estuary area, is analyzed. The temperature of surface waters on the NW shelf of the Black Sea and the Danube waters differ significantly on a seasonal scale. The Danube waters considerably cool down the surface layer of the estuarine zone during the winter months. Seasonal changes in salinity are associated not only with large seasonal fluctuations in the river flow, precipitation and evaporation, but also with seasonal variability of the wind field. In the autumn period in the spatial distribution there is an increased oxygen content off the coast of Romania, which is related to the prevailing northwestern wind in this region, which leads to the drift of the transformed Danube waters along the western coast. Due to the prevalence of southeastern winds off the Romanian coast, the Danube waters are blocked in the coastal region, which is clearly seen from the spatial distribution of oxygen. The seasonal dynamics of the pH value corresponds to the development of production processes. From winter to summer, an increase in the pH value is noted in both water areas, and then its decrease by autumn. The absolute predominance of the annual harmonic in the seasonal variability of most of the analyzed hydrological and hydrochemical characteristics in most of the examined shelf water area was confirmed. The exception is the salinity in the estuary area of the Danube. The semiannual harmonic describes more than 60% of the total variance due to the seasonal variability of salinity, which is related to the peculiarities of the wind regime in the region.

A mathematical model of estimation of thermal and effective parameters of the most important part of cogeneration system of gas piston engine working in cogeneration mode was developed. Parameters of fresh air intake stroke with variable conditions of the environment using the method of small deviations were studied. The advantages of using the method of small deviations are the possibility of linearization of calculation equations as well as making calculations of not absolute but relative parameter change. The main parameters of fresh air intake by a cylinder are parameters of combustible mixture at the end of the intake stroke: combustible mixture pressure pa, the level of compression ε, the level of heating of fresh charge during the intake ΔT, parameters of residue gases (quantity Mr, pressure pr and temperature Tr), temperature of combustible mixture Tк. Using the method of small deviations for estimation of influence of the temperature of combustible mixture on effective values of gas piston engine led to an important finding: relative change of specific effective fuel consumption (economical part of gas piston engine exploitation) is in reverse relation to squared relative difference of temperature of supercharging air. In addition, cooling of supercharging air will positively influence temperatures inside engine cylinders and consequently fuel burning temperature. In turn, lowering the fuel burning temperature will improve ecological impact of the engine and reduce exhaust of harmful components into the atmosphere, in particular NOx.

An urgent task facing the developers of unmanned underwater vehicles (UUVs) (autonomous underwater vehicles, remotely operated underwater vehicles) is to improve the accuracy of determining the output navigation parameters: orientation angles, linear velocities and location coordinates. The systems for determining the course and attitude position (Attitude and Heading Reference Systems – AHRS) and spatial positioning systems, which are supposed to equip the UUV, should not be expensive, but technologically suitable for mass production with acceptable coordinate determination accuracy. At the first stage of the research, a prototype of the navigation platform with software for it was developed and manufactured, on which experimental data from the measuring channels were obtained in laboratory conditions, and then their preliminary processing was carried out. The analysis of existing methods for increasing the accuracy of determining the output navigation parameters of unmanned underwater vehicles showed that, despite their dynamic development and constant improvement, the error in calculating coordinates when using MEMS sensors remains high and unstable. The use of an additional hydrostatic tilt unit in the navigation platform will make it possible to compensate for the errors of MEMS sensors, which require constant correction during their stable operation, unfortunately, only for a short period of time. The analysis of typical errors of MEMS sensors is carried out. The deterministic part of the error of these sensors can be eliminated by calibration, and to estimate the stochastic errors, we used the Allan variation. The obtained error values will be used in the future to form the Kalman filter of the resulting system.

Currently, several tens of subsea pipelines are in operation on the Black Sea coast of the Caucasus – sea water intakes and wastewater outlets. Wastewater outlets are divided into shallow water (up to 5 m), deep water (up to 10 m) and abyssal water (over 25 m) outlets depending on the depth of the outlet head location. Shallow water outlets are used to drain rain waters into the sea, while deep and abyssal water outlets are designed to dump purified wastewater from sewage purification plants. Most of the existing subsea pipelines were built in the 60s-80s of the 20th century and are now physically significantly worn out, partially destroyed or simply decommissioned. The pollution of the marine environment off the Black Sea coast of the Caucasus with household wastewater poses a serious threat to the local population and numerous tourists. Periodic dumping of unpurified wastewater and pipeline accidents require regular monitoring of the coastal waters. At the same time, it is possible to significantly reduce the risk of accidents on pipelines already at the design stage. In particular, a brief analysis of the natural conditions of the Russian shelf of the Black Sea coast of the Caucasus and the accident rate of subsea pipelines makes it possible to recommend the use of steel pipes in the construction of communal systems of marine water supply and sewerage. The use of plastic pipes is permissible only at depths of more than 25 m. In the upper shelf zone, the construction of completely plastic submarine pipelines is reasonable only if they are properly buried in the layer of loose bottom sediments or in the bedrock of the bench. Additionally, we can recommend application of measures to compensate for linear temperature deformations of the pipes.
