Understanding How Youth Navigate Political Information
Authors: Koren Nitzan
Published: October 2023

This work explores how we can design a Political Information Literacy (PIL) learning experience in out-of-school contexts. In collaboration with youth development and library educators and youth from historically marginalized communities, including 1.5- and second-generation immigrants, we ran participatory design sessions to identify how youth engage and make sense of political information while socially engaging and discussing misinformation, disinformation, and fake news. Preliminary findings show that youth are interested in creating positive, fun, and engaging experiences around political information and are interested in simplifying the idea of Political Information Literacy and related concepts, making sense of the connection of this concept to their lives, and making stronger connections between politics and their lives. Youth also identified a broad range of challenges, such as what they claimed to be inaccessible content, feeling insecure about their skills, experiencing information overload, and being concerned with their mental health. Youth also reported that they feel like they cannot trust what most consider reliable sources of information, as they perceive these channels as equally biased and promoting political agendas. Finally, youth were flexible thinkers, committed to listening, and respectful toward a broad range of ideas and perspectives (even when different than their own), positioning them as assets to their communities, especially around civic engagement efforts. This project continues collaborating with community partners, libraries, and immigrant youth to acquire PIL and engage in civic life.
Systematic Review of Diversity and Curriculum Improvement Case Studies
Authors: Ryan Sarah , Rashid Mohotarema
Published: October 2023

How should Library and Information Science (LIS) programs assess and refine their diversity, equity, and inclusion (DEI) instruction? We should leverage the work of health science departments. In a systematic review of DEI curriculum advancement studies published from 2010-2022, we located 46 studies concentrated in the health sciences (n=20). We found five article characteristic trends in: (1) year of publication, (2) discipline, (3) study location, (4) research methods, and (5) highly-included identity topics. We found five prevalent approaches to curricular improvement: (1) an early all-student intervention, (2) a focus on cultural humility as the outcome, (3) attention to classroom climate and safety, (4) multi-year data analysis, and (5) a working group as leader of curricular change. Throughout our project, we noted three challenges to conducting systematic reviews: (1) the U.S. bias of selected library databases, (2) missed studies due to database indexing and other issues, and (3) student coding issues. Our research suggests that dozens of strategies exist for measuring existing curricular content, that curricular change requires significant investment, and that LIS should transition to cultural humility as the focal outcome of diversity instruction.

Authors: Gao Yijun , Herrmann Amanda , Chen Chun
Published: October 2023

GIS (Geographic Information System) is a powerful tool for managing, analyzing, and presenting spatial data. It has a wide range of applications for social goods, from mapping public services (data) to analyzing the spatial distribution of information resources and use. On the other hand, ChatGPT is an AI-based chatbot that engages in natural language conversations with users. It can be trained to answer questions, provide assistance, and facilitate learning in social services and higher education. Our research combines the two technologies to find innovative and efficient ways of delivering social services and improved LIS education. For example, GIS can map out the locations of library resources, patron demographics, local history, and support other services (i.e., crisis responses). ChatGPT can provide personalized assistance and information to users based on their location and preferences. We intend to use GIS + ChatGPT to create more accessible services/APPs for the underrepresented population in community or higher education. Utilizing GIS and ChatGPT (and other generative AI services) will create more accessible and convenient ways for users to access public data, especially for the seniors and new immigrants in the Great Chicago Area. We will also explore new initiatives to improve the librarian’s professional training in “Content Engineering” and “Prompt Engineering” in the era of AI. We will also focus on the ethical implications of these technologies and ensure that they are used to respect user privacy and promote equitable access to quality information services and social justice.

The project investigates an important and uninhabitable subject, which is bonding
dissimilar materials such as - metal and making a joining between them, so the
making a join between these materials. The samples from different materials were
prepared to make a joint between them. The dissimilar materials used are the stainless steel alloy of grade 440; these alloys join with the polymer high-density polyethylene(M300054). After the preparation, the alloy samples were put in an atmospheric tube face; many experiments were performed to determine the conditions (
temperature and holding time ) that under it, the sample's surface would oxidize,
and a layer of oxide would grow on the surface of the sample. The powdered polymer was then placed on the oxidized surface of the samples. Then, many experiments were performed to determine the conditions of the powder wetting the sample's surface. AFM uses the selected alloys to determine the best oxidation condition, and t weight gain is measured to determine that the best oxidation U condition
is at a temperature of 500 C and a holding time of 60 minutes. The wetted filler is
used to verify the bonding between the sample stainless steel and the polymer. The
polymer was bonded at a temperature of 500 ° C and a holding time of 1 hour; the
joining strength equals approximately 2 MPa.

Exploring Relations Between Unique Patient Characteristics and Virtual Reality Immersion Level on Anxiety and Pain in Patients Undergoing Venipuncture: Secondary Analysis of a Randomized Control Trial (Preprint)
Authors: Gold Jeffrey I , Akbar Krystal M , Avila Sandra , Ngo Nhat H , Klein Margaret J
Published: October 2023

BACKGROUND

Virtual reality (VR) is a well-researched digital intervention that has been used for managing acute pain and anxiety in pediatric patients undergoing various medical procedures. This study focuses on investigating the role of unique patient characteristics and VR immersion level on the effectiveness of VR for managing pediatric pain and anxiety during venipuncture.

OBJECTIVE

The purpose of this study is to determine how specific patient characteristics and level of immersion during a VR intervention impact anxiety and pain levels for pediatric patients undergoing venipuncture procedures.

METHODS

This study is a secondary data analysis of 2 combined, previously published randomized control trials on 252 pediatric patients aged 10-21 years observed at Children’s Hospital Los Angeles from April 12, 2017, to July 24, 2019. One randomized clinical trial was conducted in 3 clinical environments examining peripheral intravenous catheter placement (radiology and an infusion center) and blood draw (phlebotomy). Conditional process analysis was used to conduct moderation and mediation analyses to assess the impact of immersion level during the VR intervention.

RESULTS

Significant moderation was found between the level of immersion and anxiety sensitivity when predicting postprocedural anxiety (P=.01). Patients exhibiting the highest anxiety sensitivity within the standard of care yielded a 1.9 (95% CI 0.9-2.8; P<.001)-point elevation in postprocedural anxiety relative to individuals with high immersion levels. No other significant factors were found to mediate or moderate the effect of immersion on either postprocedural anxiety or pain.

CONCLUSIONS

VR is most effective for patients with higher anxiety sensitivity who report feeling highly immersed. Age, location of the procedure, and gender of the patient were not found to significantly impact VR’s success in managing levels of postprocedural pain or anxiety, suggesting that immersive VR may be a beneficial intervention for a broad pediatric population.

Authors: Roudhoh Ummi , Romadhon Romadhon , Fahmi Ahmad Suhaeli
Published: October 2023

Sargassum duplicatum is a brown seaweed containing various chemical compounds with potential applications as a natural dye and antioxidant. These compounds include alginate, protein, vitamin C, tannins, iodine, phenols, and pigments such as chlorophyll a, chlorophyll c, fucoxanthin, xanthophyll, and carotene. Therefore, this study aimed to determine the effect of varying extraction times on the color and antioxidant quality of Sargassum duplicatum extract. One of the methods used to extract Sargassum duplicatum is ultrasonication, which involves using ultrasonic waves to break down the cell walls of the material and facilitate efficient compound extraction. The extraction was carried out at 15 (A), 30 (B), and 45 minutes (C), with three repetitions for each treatment. The assessed parameters included yield calculation, total carotenoids, antioxidant activity, and color intensity. Parametric data were analyzed using ANOVA and Tukey HSD follow-up tests. The extraction process used an 80% ethanol solvent at 40 °C and a frequency of 42 kHz. This study employed an experimental laboratory approach using a completely randomized design (CRD) with different extraction times. The results showed significant differences (p<5%) in yield value, total carotenoids, antioxidant activity, and color intensity of Sargassum duplicatum extract at different extraction times. The best results were obtained at 45 minutes, yielding 86.66%, with 9.62% total carotenoids, an IC50 value of 1241.02 ppm, and lightness (L*), redness (a*), and yellowness (b*) values of 4.44, -3.46, and 37.90, respectively.

Authors: Ihsani Nisa
Published: October 2023

The transformed plant tissue sections through the agroinfiltration method are difficult to be observed under a fluorescent microscope. It is due to the softness of the post-transformation explant. This research was conducted to optimize the sectioning of the transformed plant using the agarose embedding technique. The optimization method was carried out in various agarose concentrations: 2%, 4%, and 6%, followed by five minutes of incubation in various temperatures: -80 oC, 4 oC, and 25 oC. The results showed that the embedding method using 6% agarose produced a transformed plant section was better than 2% and 4% agarose. Meanwhile, the incubation method at 25 oC was more suitable for the transformed plant tissue than 4 oC and -80 oC. Green Fluorescent Protein (GFP) could be determined using these methods under a fluorescent microscope. Thus, the optimum method for making sections of transformed plants by embedding was using 6% agarose then incubating at 25 oC for 5 minutes.

Authors: Liani Triana April , Mu'am Ahmad
Published: October 2023

This study examines gender bias by identifying semiotic indicators in YouTube advertisements. This study employs a qualitative descriptive methodology. The data consists of three YouTube advertisements for cashback applications, namely ShopBack (2018), Pomona (2018), and Fave (2019). This advertisement's semiotic signs are analyzed through the lens of Charles Sanders Peirces' Triadic Semiosis theory. In the meantime, Widyatama's categorization of Gender Bias in Television Commercials (2007) is utilized to examine gender bias in the three advertisements based on physical and psychological characteristics, regions of roles, and relationships between men and women. The data analysis found that this advertisement contained multiple examples of gender bias. Physically, female characters are shown for their beauty, and psychologically, they are portrayed for their emotions. This bias is also frequently manifested in the subordination and domestication of women. Women are typically portrayed doing domestic chores, even though they are seen outside the home. Women are considered subservient, perpetually subordinate, weak, and vulnerable compared to men.

Published: October 2023

Abstract: The objective of this project is to create a device designed to identify instances of reckless driving on highways and promptly notify traffic authorities about speeding violations. Incidents resulting from careless driving on highways have been steadily increasing, leading to a growing number of fatalities caused by the errors of others. It is imperative that drivers adhere to the prescribed speed limits while on highways. Nevertheless, instances of speeding-related accidents persist, as drivers rely on their vehicle's speedometers to monitor their speed and decelerate when they perceive they are surpassing the acceptable limits. Highway speedometers prove to be a valuable tool for law enforcement, particularly in the battle against speeders, given their digital display and the incorporation of an alert mechanism, such as a buzzer or alarm, to detect and signal when a vehicle's speed exceeds the legalthreshold. To address this issue, we have implemented a circuit known as a highway speedometer.

Published: October 2023

Abstract: In order to produce closed and open coil helical springs, this study will explain the design and construction of a manual spring rolling machine using a straightforward mechanism setup. Manual labour is used to run this machine. With the help of this equipment, closed coil helical springs with various diameters and lengths may be produced. Metal wire is bent into a curved shape by rolling. The spherical object is produced by a spring roller shaft. On a rolling equipment that is powered or controlled manually, rolling can be done. From a shaft, it may create a spring. A shaft is a revolving machine component that transfers power from one location to another. A bearing is a mechanical component that supports another moving mechanical component. The spring's lead is responsible for this self-motion. The rolling machine's handle allows for manual operation; without electric power, the frame, which is built of mild steel, supports all of the machine's components. The mandrel is held in place by a work holding device that is fastened to the machine's main shaft. The mandrel's outer diameter corresponds to the internal diameter of the spring when it is fitted in the work-holding mechanism.

Published: October 2023

Friction Stir Welding (FSW) is a solid-state bonding process that employes tools that are not used up and can function to connect two opposite workpieces without melting the workpiece material. The friction force has been micro-structurally tested to reformat or transform the inner state of the structure properties (atomic formation) form in metal since the kinetic energy of friction has been utilised in one of the welding techniques. Right afterwards, the studies reported that the mechanical properties also underwent a significant deformation. The aim is to determine the effect of Welding Procedure Specification (WPS) product quality. As it develops through research and applied experiments, the branch of friction-based welding discipline can be classified depending on how the friction mechanism can produce the finest solid-state joint, which is suitable to the typical property of metal and can be maximised by joint configuration. Friction Stir Welding is a friction-based welding technique that uses the stirring tool to generate friction while the workpieces are stuck on the line of the FSW joint configuration. The relevant correlations amongst process parameters and inside its respective adjustable variables are constructed to the finest principles that produced top-grades empirical reports of the weld properties. In this review, the explanation of the working principle and clarification of process parameters are presented. The cited references are selected from creditable and verifiable articles and books in the last ten years. Expectedly, it will be able to pioneer a new face of simple and understandable review articles.

Authors: Saputra Bagus Adi , Nurato Nurato
Published: October 2023

The performance capability of the steam turbine under factory conditions will experience changes that can be caused by operating or environmental factors. Therefore, it is necessary to analyze the performance of the steam turbine during the actual condition so that it can be compared with the performance of the steam turbine from the manufacturer using mass and energy balance equations on HP heater #1 and deaerators and iteration methods. The research was conducted by looking at the phenomena that occur in the steam turbine using mathematical models and theories when the unit operates according to the heat balance design parameters. Feedwater flow from the calculation of the iteration method based on the equation of the water heater obtained a value of 17,961.58 kg/h. The performance steam turbine experienced a decrease in efficiency with a value for isentropic efficiency of 72.73% down 6.54% from the design value of 79.27% and thermal efficiency of 26.88% down 1.75% from the design value of 28.64%. Meanwhile, the steam rate value of 5.03 kg/kWh increased by 0.44 kg/kWh from the design value of 4.59 kg/kWh, and the turbine heat rate of 3198.83 kcal/kWh, an increase of 196.08 kcal/kWh from the design value of 3002.75 kcal/kWh.

Published: October 2023

This study aimed to develop an innovative propeller turbine design to facilitate easy manufacturing and maintenance processes, leading to a reduction in costs. Furthermore, the Analytical Hierarchy Process (AHP) method was employed to identify the most optimal model and design for the propeller turbine. Problem-solving within the AHP framework was guided by three fundamental principles, namely decomposition, Comparative Judgment, and Logical Consistency. The procedure included problem decomposition, assessment/ weighting to compare elements, matrix preparation and consistency testing, setting priorities for each hierarchy, priority synthesis, and decision-making. To establish a benchmark, three types of propeller turbines currently available in the market served as references. Meanwhile, the selection criteria for the model were based on several factors, including power factor, time efficiency, ease of manufacture, as well as production and maintenance costs. Considering the criteria, modifications were made to these reference models, resulting in the development of alternatives, denoted as A, B, and C. The results showed that alternative type A as the most suitable choice for further development. Therefore, this particular design was granted foremost priority to develop a low-head generator that possessed ease of manufacturing and surpassed alternative models in terms of feasibility.

Published: October 2023

Public green open space management currently tends to be in strategic areas in Denpasar City, such as the Sanur coastal area, city center, and city roads. This centralization will, in time, create a feeling of saturation and require a new atmosphere and unequal development. One of the efforts is to explore the potential of vacant land in coastal areas that have yet to be touched by development, one of which is the estuary of the Ayung River. The community currently uses the edge of the estuary of the Ayung River for recreational activities. The first step is to have a design that supports this function, especially since this area has ecological benefits for the city. The research objectives can accommodate the community's needs, managers, regional potential, and sustainable landscape design approaches. The analysis technique used is descriptive analysis technique using walkability analysis and triangulation approaches. The results of the study integrate the theory of sustainable coastal area landscape design by producing design criteria, namely: Socio-cultural function design criteria with the principle approach of environmental community involvement, Economic function design criteria with the application of the economic tenets involving Small and Medium Enterprises (SMEs), Environmental function criteria with the principles of waste management, linkage criteria with an energy efficiency function approach, and aesthetic function design criteria with a safe and comfortable material principle approach.

Authors: Trinh Jonathan , Acosta Cassaundra , Easwar Arti , Galamaga Robert , Tan Alan
Published: October 2023

Background: Sinonasal undifferentiated carcinoma (SNUC) is an
exceedingly rare head and neck malignancy. No consensus exists on
treatment for metastatic disease.

Case: A 56-year-old female was diagnosed with SNUC after endorsing sinus
congestion, diplopia, and right orbital pain. Initially treated with
surgery and radiation, she later developed significant metastatic
disease. She demonstrated progression of her hepatic metastases under
pembrolizumab therapy. However, the addition of ipilimumab and a COX-2
inhibitor resulted in significant improvement in her lesions as well as
an ongoing durable response. Her regimen was complicated by
immune-related adverse events successfully treated with steroids.

Conclusion: Dual checkpoint inhibition deserves consideration when
treating metastatic SNUC, especially after single agent therapy has
failed. The positive effect of this treatment may be augmented by IDO1
inhibition.

Predators can affect ecosystems through non-consumptive effects on their
prey, which can lead to cascading effects on the vegetation. In
mammalian communities, such cascading effects on whole ecosystems have
mainly been demonstrated in protected areas, but the extent to which
such effects may occur in more human-dominated landscapes remains
disputable. With the recolonisation of wolves (Canis lupus) in Europe,
understanding the potential for such cascading processes becomes crucial
for understanding the ecological consequences of wolf recovery and
making appropriate management recommendations. Here, we investigate the
evidence for non-consumptive effects of wolves on their wild ungulate
prey and cascading effects on the vegetation in European landscapes. We
reviewed empirical studies reporting wild ungulate responses to wolves
involving spatio-temporal behaviour at large and fine spatial scales,
activity patterns, vigilance, grouping, physiological effects, and
effects on the vegetation. We reveal that non-consumptive effects of
wolves in Europe have been studied in few regions and with focus on
regions with low human impact and are highly context-dependent and might
often be overruled by human-related factors. Further, we highlight the
need for a description of human influence in NCE studies. We discuss
challenges in NCE research and the potential for advances in future
research on NCE of wolves in a human dominated landscape. Further, we
emphasise the need for wildlife management to restore ecosystem
complexity and processes, to allow non-consumptive predator effects to
occur.

OBJECTIVE

Continuous glucose monitoring (CGM) improves maternal glycemic control and neonatal outcomes in type 1 diabetes pregnancies compared with self-monitoring of blood glucose. However, CGM targets for pregnancy are based on expert opinion. We aimed to evaluate the association between CGM metrics and perinatal outcomes and identify evidence-based targets to reduce morbidity.

RESEARCH DESIGN AND METHODS

This was a retrospective cohort study of pregnant patients with type 1 or 2 diabetes who used real-time CGM and delivered at a U.S. tertiary center (2018–2021). Multiple gestations, fetal anomalies, and early pregnancy loss were excluded. Exposures included time in range (TIR; 65–140 mg/dL), time above range (TAR), time below range (TBR), glucose variability, average glucose, and glucose management indicator. The primary outcome was a composite of fetal or neonatal mortality, large or small for gestational age at birth, neonatal intensive care unit admission, hypoglycemia, shoulder dystocia or birth trauma, and hyperbilirubinemia. Logistic regression estimated the association between CGM metrics and outcomes, and optimal TIR was calculated.

RESULTS

Of 117 patients, 16 (13.7%) used CGM before pregnancy and 68 (58.1%) had type 1 diabetes. Overall, 98 patients (83.8%) developed the composite neonatal outcome. All CGM metrics, except TBR, were associated with neonatal morbidity. For each 5 percentage-point increase in TIR, there was 28% reduced odds of neonatal morbidity (odds ratio 0.72, 95% CI 0.58–0.89). The statistically optimal TIR was 66–71%.

CONCLUSIONS

Nearly all CGM metrics were associated with adverse neonatal morbidity and mortality and may aid management of preexisting diabetes in pregnancy. Our findings support the American Diabetes Association recommendation of 70% TIR.
Nipah Virus and Bacteria Infections: Cardiac Complications in Maternal Health
Authors: S Mattapally
Published: October 2023

As a zoonotic virus, the nipah virus (NiV) can pass from people to animals. A novel paramyxovirus called NiV, which is related to the Hendra virus and has spread globally, has had tremendous impact on people's life. Numerous investigations have shown that NiV and SARS-CoV, the zoonotic virus that was responsible for the 2002 outbreak of severe acute respiratory syndrome, have a lot in common biologically. While NiV alone can also cause myocardial damage, pre-existing cardiovascular illness appears to be associated with worse results and an increased risk of death in individuals with the virus. Emerging infections include both newly emerging and re-emerging infections that have an increasing occurrence over the past few decades or threaten to do so. A new infectious agent entering the community, a previously unknown circulating agent being discovered, or the discovery that an infection is the true cause of a noncommunicable disease.

Introduction. A high level of anxiety is identified in people with somatic illness of different genesis. The study of anxiety manifestations in adolescents with low physical status can contribute to the development of the negative emotional states correction system. We will identify and describe the expressiveness of various anxiety aspects of the personality in adolescents with low physical status, whose bodies are in the stage of active change and development. This is precisely where the novelty of the research lies.

Purpose. In the article, we will study the characteristics of anxiety in adolescents with various physical status.

Materials and Methods. There were two groups of adolescents (15–17 years of age): with low physical status (students of residential schools in Rostov-on-Don) and normal (students of regular schools). The sample consists of 130 respondents. We used the “Multidimensional assessment of childhood anxiety” method (L. I. Vasserman & E. E. Malkova) for diagnosing anxiety characteristics.

Results. Specific anxiety profiles in people with various physical well-being are reflected. We have identified that adolescents with low physical status have significantly higher levels of general anxiety and anxiety associated with self-expression compared to students with normal physical status. Anxiety associated with sensitivity to opinion of the others and with relationships with peers is higher in adolescents with somatic illness.

Discussion and Conclusion. Somatic illness and physical status in general have an impact on adolescents’ psychological well-being, and especially on their personality and emotional sphere. Understanding of the subjective characteristics of the anxiety profile and the specifics of the emotional expressions of the personality with somatic troubles will help to design effective programs for psychological support.

Published: October 2023

Introduction. The expansion of informational and communicational space as well as an increase in the volume of contacts for communication draw attention to the study of communicative potential in professionals of various fields. This issue is considered within fields of sociology, communication and political science, philosophy, and psychology. A modern specialist has a need for communicability not only for success in professional tasks, but also for stable client capture and impactful communication with them. Moreover, the ability plays a special role in effective organization of the working process in a positive and productive way. This section highlights the role of the communicative potential of the personality in professional activity. Dynamism, as one of its characteristics, creates an education possibility applying throughout the entire working process.

Purpose. Our article is devoted to the theoretical generalization of the empirical data obtained by foreign and Russian researchers in the study of communicative potential in professionals of various fields.

Theoretical justification. Characteristics of communicative potential are identified for each of the following occupational groups: “human-machine”, “human-nature”, “human-human”, “human-sign system”, “human-art image”. It is done on the example of the work in pedagogy, healthcare, administration, creative, digital, and technical fields. This article deals with the main directions and research results on the communicative potential of the personality in the chosen professions.

Discussion. We considered the main modern directions in the work of foreign and Russian researchers on the problem of the communicative potential of the personality according to the profession type. Research objectives in this area are also stated. The analysis showed that the communicative potential of the personality is gaining importance as part of professional competence in the modern conditions, regardless of the professional activity type. Nowadays specialists in the fields of “human-sign system”, “human-machine”, “human-nature” professions, as well as in the socionomy area, need specific communicative training, developing communicative abilities and skills.
Prospects of Studying the Meaning-Making Avoidance Coping
Authors: Godunov M. V. , Portnov E. A.
Published: October 2023

Introduction. The importance of studying meaning-making avoidance coping classified as maladaptive is emphasized. Avoidance coping makes it impossible for one to behave adequately in the communication situation.

Purpose. In this article, we will methodologically justify the structure of the original questionnaire for avoidance coping in the form of a partial semantic differential and a set of personal trait scales included in it.

Theoretical Justification. We described the foundations and specifics of the expression of meaning-making avoidance coping. This strategy consists of shifting away from the problem, idleness, carelessness, and immaturity of the personality, the will to stay in the comfort zone, procrastination, escapism, hedonism, as well as diving into virtual space. We presented our method for studying avoidance coping specifics in the form of a partial semantic differential of personal traits. When designing it, we proceed from the phenomenon of meaning consonance and dissonance as a match and mismatch. The original method consists of nine bipolar semantic scales of personality traits as special indicator marks of meaning. The validation will be conducted on the sample of 300 respondents. We will also use certified methods from related psychodiagnostic spheres: “Life-Purpose Orientations” (LPO) by D. A. Leontiev, Amirkhan’s Coping Strategy Indicator (CSI) adapted by V. N. Yaltonsky and N. A. Sirot, the Thomas-Kilmann Conflict Mode Instrument (TKI) adapted by N. V. Grishina, the Melbourne Decision Making Questionnaire adapted by T. V. Kornilova, and the New Uncertainty Tolerance Questionnaire (NTQ) by T. V. Kornilova.

Discussion. We are certain that this particular approach will form a battery of tests appropriate for study on avoidance coping aspects. It is possible to empirically reveal multi-type portraits related to the value-meaning sphere of subjects who show the avoidance coping strategy, if the ensemble mechanisms of personal trait structure are taken as a basis. Those multi-type models of current meaning states not only are effective in a person’s behaviour prediction, but they also imply cost-friendly test technologies.
