"A three-dimensional nonlinear differential system for modeling inflation rate in a given economy is proposed and investigated in this article. Using a bifurcation-based method in the study, we describe the conditions leading to regions of stability for the long-term behavior of the model, which are economically desirable, along with regions of instability, which should be avoided in an economy."

"In this paper we have presented an approach to deal with decision making problems. For this purpose we have constructed a fuzzy set, namely D-fuzzy set, for a soft set. This concept of D-fuzzy set will also be used when the information is given in form of weighted soft set, fuzzy soft set or weighted fuzzy soft set. Further we will apply this method when there are more than one observer. We will define such sets as multi-observer soft set, multi-observer weighted soft set etc."

Graphitic andesite tuffs resulting from high-Mg tholeiite and sediment interaction; Nfigssuaq, West Greenland
Authors:   Geologisk Museum, Pedersen Asger Ken
Published: March 2022

Tuffs from the Agatdal Formation of Nilgssuaq show a dominance of olivine-graphite-andesites and orthopyroxe'ne-graphite-andesites while rock types similar to the overlying tholeiite basalts of the Vaigat Formation are subordinate. The tuffs were formed when highly magnesian tholeiitic picrite melts were emplaced into high-level magma chambers within carbon-rich sedimentary strata. Explosive reactions were triggered after extensive reactions with- the sediments. Glass grains are well preserved and some tuffs still contain quenched high-temperature sulphide blebs with metallic iron. Due to the high magnesium content the graphite-andesites are very unusual magma types and can be compared to some native iron bearing intermediate lavas from the Vaigat Formation of northern Disko thought to have erupted largely contemporaneously after having evolved through similar processes.
Child-oriented word associations improve models of early word learning
Authors: Cox Christopher R. , Haebig Eileen
Published: March 2022

How words are associated within the linguistic environment conveys semantic content; however, different contexts induce different linguistic patterns. For instance, it is well known that adults speak differently to children than to other adults. We present results from a new word association study in which adult participants were instructed to produce either unconstrained or child-oriented responses to each cue, where cues included 672 nouns, verbs, adjectives, and other word forms from the McArthur–Bates Communicative Development Inventory (CDI; Fenson et al., 2006). Child-oriented responses consisted of higher frequency words with fewer letters, earlier ages of acquisition, and higher contextual diversity. Furthermore, the correlations among the responses generated for each pair of cues differed between unconstrained (adult-oriented) and child-oriented responses, suggesting that child-oriented associations imply different semantic structure. A comparison of growth models guided by a semantic network structure revealed that child-oriented associations are more predictive of early lexical growth. Additionally, relative to a growth model based on a corpus of naturalistic child-directed speech, the child-oriented associations explain added unique variance to lexical growth. Thus, these new child-oriented word association norms provide novel insight into the semantic context of young children and early lexical development.

Authors: Al-A'ssam Dr. Saja AbdulAmeer , Sukker Zainab Hilal
Published: March 2022

The language of newspapers helps people learn a wide range of topics. Its language serves primarily as a means of conveying information. Besides persuading and entertaining the people, that is what makes its style special. Its vocabularies and sentence structure have to be chosen efficiently to affect all readers. Hence, this study seeks to analyze texts from British newspapers to determine how journalists use language when reporting on some sensitive subjects, such as the writing on the current topic that has occupied the global press, Covid19. Therefore, this study sets to fulfil several aims; the most important of them are identifying the stylistic features at the syntactic and lexical levels used in The Guardian and The Sun newspaper news on the coronavirus pandemic. Besides, it aims at finding out the similarities and differences at the levels mentioned above between the Guardian and the Sun newspapers news on that specific subject.
Forecasting the Movement of Renewables Stocks Using BSE Energy Index1
Authors: Nandy Ankita
Published: March 2022

Coincident to the dip in the demand of conventional sources of energy like coal, oil and gas as the pandemic progressed has been a surge in the global demand for environment friendly practices, putting the spotlight on energy generated from renewable sources. The Renewables sector has found favor and is witnessing steady rise on a global level. Though a minor contributor to the power generation in India, this sector is deemed to grow in the coming years as India strives to reduce its CO2 emissions, making the related instruments lucrative investment options. Stock exchanges are critical to the economic health of a nation and the pandemic led to major crashes in several exchanges around the world. Investment firms can employ deep learning models to forecast the movement of the market and thus assure their customers of high returns in the high-risk environment, cutting through the general pessimism pervading the investment sphere post-pandemic. This work builds forecasting models for two such stocks using neural networks. Selecting the BSE as the universe of study, two companies are selected and modelled across two techniques: LSTM and Bidirectional LSTM, employing three different feature sets. The inclusion of BSE Energy Index in the models alongside the historical prices enables capturing the influence of external elements on the energy market.

Visual impairment during childhood hinders children's neurological progress, markedly impacting their physical, psychological, social, and emotional health. Yoga's multifarious approach can help children with visual impairment to cope with their challenges. The research was conducted with an objective to develop a Yoga based Intervention Program for Students with Visual Impairment and to measure its impact on their health. Experimental method of research with one group pretest-posttest design was used by the researcher. 39 visually impaired adolescent students were taken as sample chosen by Purposive Sampling technique. The intervention program consisted of yogic prayer, warm up exercises, asanas, pranayams, meditation etc. The program was conducted for two months, one hour session per day for six days per week. The Cornell Medical Index Health Questionnaire (Visually Handicapped) was used to assess the health of students with visual impairment. The results conveyed that there was a positive impact of Yoga Intervention Program on health of students with visual impairment. The intervention was found successful for both the dimensions of health i.e. physical health and psychological health. Further, yoga intervention was found beneficial for all the sub-dimensions of physical and psychological health.
Doppler Effect and Acoustic Trails of Neutrinos
Authors: Belyakov Askold Sergeevich
Published: March 2022

In the monitoring mode, signals averaged over 1 minute were recorded in four one-third octave bands: 30, 160, 500 and 1200 Hz. Sometimes, audio signals were recorded using a computer sound card. These signals had varied and surprising forms, but there was no technical capability to record them in monitoring mode. This opportunity appeared in California in 2015. In the period from 2015 to 2017, in the SAFOD pilot well in California at a depth of 1000 m with coordinates 35.974257 N, -120.552076 W, seismological surveys were carried out for the first time using the innovative MIG-3V geophone with a wide band in the infrasonic and sound frequency ranges and in the amplitude range of more than 240 dB. In August 2016, a similar geophone for the same purpose was installed in the VGS well with coordinates 56.967017 N, 43.720605 E to a depth of 1400 m. Digital data in the automatic monitoring mode was recorded continuously every 0.1 ms. Analysis of the data obtained in the SAFOD well (more than 4 TB) showed that, along with seismic signals, there are acoustic traces in the data, which have never been observed in the wells before. Similar tracks were observed in the VGS well. Acoustic trails similar in shape and frequency are observed in the aquatic environment of lakes and Oceans when searching for acoustic trails from high-energy cosmic particles, in particular, with the help of acoustic neutrino detectors.

Pseudoplectania africana (Sarcosomataceae, Pezizales), a new species from South Africa
Authors: Sochorová Zuzana , Carbone Matteo , Sedlářová Michaela , Polhorský Adam , Sochor Michal
Published: March 2022

Background: An undescribed species of Pseudoplectania was found during an excursion in Mpumalanga.Objectives: To describe Pseudoplectania africana M.Carbone & Sochorová as a new species and to evaluate presence of crystals as a diagnostic character in Pseudoplectania.Methods: The description was based on standard macro- and microscopical methods. Presence of crystals was tested for in UV light. Phylogeny was inferred using sequencing of the LSU and ITS loci.Results: Pseudoplectania africana is characterised by shortly stipitate to sessile apothecia up to 18 mm broad, richly developed basal tomentum, ascospores with an eccentrically positioned, relatively small sheath, straight, sometimes bifurcate paraphyses, wavy to coiled external hairs and presence of large yellow crystals mainly in the hymenium and ectal excipulum. It was found on a decaying coniferous trunk. The species forms a distinct lineage in the clade with P. tasmanica and P. ericae. All of these three species exhibited presence of the large yellow crystals (sulphur yellow in UV light). No or only small hyaline crystals (whole mount blue in UV light) were found in P. nigrella, P. lignicola, P. episphagnum and P. melaena.Conclusion: The new species represents the first report of Pseudoplectania in South Africa and probably also in the whole of continental Africa. Crystals in hymenium and excipulum appear to be an important trait in Pseudoplectania taxonomy.

Thermal Properties of 1847 WISE-observed Asteroids
Authors: Hung Denise , Hanuš Josef , Masiero Joseph R. , Tholen David J.
Published: March 2022

We present new thermophysical model fits of 1847 asteroids, deriving thermal inertia, diameter, and Bond and visible geometric albedo. We use thermal flux measurements obtained by the Wide-field Infrared Survey Explorer (WISE) during its fully cryogenic phase, when both the 12 μm (W3) and 22 μm (W4) bands were available. We take shape models and spin information from the Database of Asteroid Models from Inversion Techniques (DAMIT) and derive new shape models through lightcurve inversion and combining WISE photometry with existing DAMIT lightcurves. When we limit our sample to the asteroids with the most reliable shape models and thermal flux measurements, we find broadly consistent thermal inertia relations with recent studies. We apply fits to the diameters D (km) and thermal inertia Γ (J m−2 s−0.5 K−1) normalized to 1 au with a linear relation of the form

, where we find α = 2.667 ± 0.059 and β = −0.467 ± 0.044 for our sample alone and α = 2.509 ± 0.017 and β = −0.352 ± 0.012 when combined with other literature estimates. We find little evidence of any correlation between rotation period and thermal inertia, owing to the small number of slow rotators to consider in our sample. While the large uncertainties on the majority of our derived thermal inertia only allow us to identify broad trends between thermal inertia and other physical parameters, we can expect a significant increase in high-quality thermal flux measurements and asteroid shape models with upcoming infrared and wide-field surveys, enabling even more thermophysical modeling of higher precision in the future.
The modern phase of the polysilicon market
Authors: Naumov Arkady V. , Orehov Dmitry L.
Published: March 2022

The current condition and outlooks of the world semiconductor and polycrystalline silicon (poly-Si) markets have been analyzed. A long period of low PS prices which hindered the growth of investments into the industry has now changed for price recovery to an investment attractive level. Demand and offer balance for the period until 2024 and for the long term has been analyzed, and the main currently used PS processes have been reviewed. The current poly-Si market proficiency is expected to remain in the near and medium terms. However the “green turn” of the energy industry announced by all the governments, the development of local markets and the price recovery to an investment attractive level have promoted the development of new PS fab projects. Of special importance for Russia is the choice of Siemens trichlorosilane process parameters. A specific feature of the Russian market is the presence of several very important fields (solar energy, microelectronics, high-power electronics, photonics and fiber optics) which are small by international standards and equally face raw material shortage. It appears that Russia will greatly benefit from integral projects delivering solutions of multiple raw materials supply problems.
Exploring Nursing Students' Experiences With Different Teaching Pedagogies: A Mixed-Methods Study
Authors: Browne Caroline , Wall Peter , Walters Jennifer
Published: March 2022

Background:

Educational methods continue to evolve to meet the challenge of teaching undergraduate nursing students. Innovative teaching pedagogies require nursing students to be actively involved in their own learning compared with traditional didactical styles.

Method:

Students were exposed to three distinct teaching pedagogies: inquiry-based, online, and educator-led during their second year of study. Students' learning preferences were explored using a mixed-methods approach. Quantitative data were collected using an online questionnaire, followed by a focus group interview.

Results:

The quantitative data revealed students preferred being taught directly from educators rather than through self-directed and online study. Manifest content analysis of qualitative data revealed four categories that supported student learning and five categories that hindered student learning.

Conclusion:

Students struggled when required to be self-directed in their learning. Students reported feeling uncertain and overwhelmed initially, which highlighted the importance of strong social and academic support to facilitate effective learning.

This article contracts through Cauchy problems in infinite-dimensional Banach spaces towards a system of nonlinear non-autonomous mixed type integro-differential fractional evolution equation by nonlocal conditions through noncompactness measure (MNC). We demonstrate the existence of novel mild solutions in the condition that the nonlinear function mollifies generally adequate, an MNC form and local growth form, using evolution families and fractional calculus theory, as well as the fixed-point theorem w.r.t. K-set-contractive operator and another MNC assessment procedure. Our findings simplify and improve upon past findings in this area. Finally, towards the end of this article, as an example of submissions, we use a fractional non-autonomous partial differential equation (PDE) with nonlocal conditions and a homogeneous Dirichlet boundary condition.
Diagnosis of each main coronary artery stenosis based on whale optimization algorithm and stacking model
Authors: Jin Ziyu ,   College of Sciences, Northeastern University, Shenyang 110819, China, Li Ning
Published: March 2022

Cardiovascular disease is currently one of the diseases with high morbidity and mortality worldwide. One of the main types is coronary artery disease (CAD), which occurs when one or more of the three main arteries, the left anterior descending (LAD) artery, the left circumflex (LCX) artery, and the right coronary artery (RCA), are narrowed. In this paper, we introduce a computer-aided diagnosis model, which uses the k-nearest neighbor (KNN)-based whale optimization algorithm (WOA) for feature selection and combines stacking model for CAD diagnosis and prediction. In WOA, the values in the solution vectors are all continuous, and a threshold is set for binary-conversion to obtain the optimal feature subsets of each main coronary artery. Then we develop a two-layer stacking model based on the selected feature subsets to diagnosis LAD, LCX and RCA. By the proposed method, we select 17 features for each main artery diagnosis, and the classification accuracy on LAD, LCX, and RCA test sets is 89.68, 88.71 and 85.81%, respectively. On the Z-Alizadeh Sani dataset, we compare the proposed feature selection method with other metaheuristics and compare the performance of WOA based on different wrappers. The experimental results show that, the KNN-based WOA method selects the optimal feature subsets, and the classification performance of the stacking model is better than other machine learning algorithms.
Comparaciones basadas en biomarcadores de crudos extraídos de la Formación Springhill (Cuenca Austral) y de la Formación Bajo Barreal (Cuenca Golfo San Jorge), Argentina
Authors: Tomas Germán Javier , Acuña Adrián Javier
Published: March 2022

En Argentina existen varias cuencas productivas de petróleo, entre ellas las Cuencas Golfo San Jorge y Austral. Sus sucesiones estratigráficas contienen varias unidades que actúan como rocas reservorio, destacando en este estudio las formaciones Bajo Barreal (98 Ma) y Springhill (134 Ma). El objetivo de este trabajo fue comparar crudos extraídos de estas formaciones usando biomarcadores geoquímicos orgánicos: saturados (n-parafinas, isoprenoides acíclicos pristano y fitano, esteranos y terpanos) y aromáticos (fenantrenos y dibenzotiofenos) para establecer similitudes y diferencias respecto al tipo de materia orgánica que les dio origen, el grado de biodegradación alcanzado por los mismos y, por otro lado, determinar la litología y las condiciones de depósito que controlaron la acumulación y preservación de la materia orgánica en sus rocas madre. Los crudos fueron sometidos a una separación de sus fracciones alifáticas y aromáticas por cromatografía de adsorción sólido-líquido en columna y cada uno de estos extractos obtenidos fue analizado mediante cromatografía de gases acoplada a espectrometría de masas (GC-MS). A partir de las relaciones de diagnóstico, calculadas con las abundancias relativas de los biomarcadores, se sugiere para los crudos de la Formación Springhill que la materia orgánica precursora fue de tipo mixto marino - continental, depositada en un ambiente con concentración moderada de oxígeno (disóxico-subóxico), en el cual la roca madre se caracterizó por ser de naturaleza marina siliciclástica, y no se observó biodegradación de estos. Por otro lado, los crudos asociados a la Formación Bajo Barreal son de tipo algal-lacustre severamente biodegradados, sedimentados en condiciones de anoxia en una roca generadora tipo carbonática. Estos resultados concuerdan con estudios previos realizados sobre crudos provenientes de otros yacimientos de ambas formaciones, pero lo novedoso radica en que estas localizaciones nunca fueron estudiadas.
NLRP1B and NLRP3 Control the Host Response following Colonization with the Commensal Protist Tritrichomonas musculis

Published: March 2022

Commensal intestinal protozoa, unlike their pathogenic relatives, are neglected members of the mammalian microbiome. These microbes have a significant impact on the host’s intestinal immune homeostasis, typically by elevating anti-microbial host defense. Tritrichomonas musculis, a protozoan gut commensal, strengthens the intestinal host defense against enteric Salmonella infections through Asc- and Il1r1-dependent Th1 and Th17 cell activation. However, the underlying inflammasomes mediating this effect remain unknown. In this study, we report that colonization with T. musculis results in an increase in luminal extracellular ATP that is followed by increased caspase activity, higher cell death, elevated levels of IL-1β, and increased numbers of IL-18 receptor–expressing Th1 and Th17 cells in the colon. Mice deficient in either Nlrp1b or Nlrp3 failed to display these protozoan-driven immune changes and lost resistance to enteric Salmonella infections even in the presence of T. musculis. These findings demonstrate that T. musculis–mediated host protection requires sensors of extracellular and intracellular ATP to confer resistance to enteric Salmonella infections.
Professional Socialization: A Retrospective View From Graduation to Full-Time Employment
Authors: Harper Megan , Singe Stephanie M. , Ostrowski Jennifer
Published: March 2022

Context

It is assumed that after the transition to practice, athletic trainers will have developed stronger decision-making strategies, will have become comfortable within their role, and will be able to reflect on how their employer assisted them through the transition-to-practice process.

Objective

The goal of this study was to gain an understanding of how athletic trainers have gone through the transition-to-practice process and what resources they relied on during and after the transition.

Design

Qualitative study, phenomenological design.

Setting

Semistructured interviews.

Patients or Other Participants

Twelve athletic trainers (10 women, 2 men; 4.0 ± 2 years certified) agreed to participate. Data saturation guided the total number of participants for this study.

Data Collection and Analysis

Videoconference interviews were recorded and transcribed verbatim using Zoom. Credibility of the study was maintained using several mechanisms, including expert/peer review, member checks, and researcher triangulation.

Results

Two themes emerged as different points in time of the athletic trainer's transition to practice. The first theme was pre–entrance into the workforce, and within this theme, athletic trainers were able to reflect on the strategies and resources that were provided to them by their professional master of athletic training program. Within the second theme, post–entrance into the workforce, athletic trainers were able to recall the resources that were provided to them by their employers and those additional resources that were sought out individually.

Conclusions

Athletic trainers recognized how their master of athletic training programs prepared them for the transition-to-practice process based on the didactic coursework and intentional clinical education experiences. Athletic trainers also recognized the resources that were and were not provided to them to assist them in fulfilling their roles and responsibilities, as well as realizing the additional resources they needed to enhance their own clinical practice.
Anti-inflammatory and antipyretic potential of Arbutus andrachne L. methanolic leaf extract in rats
Authors: Jaffal Sahar M. , Oran Sawsan A. , Alsalem Mohammad I.
Published: March 2022

Objective:

To explore the anti-inflammatory and antipyretic effects of methanolic leaf extract from Arbutus andrachne and its mechanism of action.

Methods:

Paw edema was induced by intraplantar (i.pl.) injection of λ-carrageenan (1% w/v, 100 μL/paw) while pyrexia was evoked by intraperitoneal (i.p.) injection of 20% baker's yeast (20 mL/kg body wt) in male Wistar rats. The anti-inflammatory and antipyretic effects of Arbutus andrachne methanolic leaf extract were explored by injecting rats with different doses of the plant extract (150, 300, and 600 mg/kg body wt, i.p.). Selective antagonists for transient receptor potential vanilloid-1 (TRPV1), cannabinoid receptor 1 (CB1), and alpha-2 adrenergic receptor (a2-AR) were used to unravel the extracts’ mechanism of action. Blood samples were collected from the heart of rats to measure the levels of interleukin-6 (IL-6) and prostaglandin E2 (PGE2) by enzyme-linked immunosorbent assay.

Results:

The extract exhibited potent anti-inflammatory activity by decreasing paw thickness and IL-6 levels. In addition, yeast-evoked pyrexia was attenuated by the extract treatment via TRPV1 and CB1 receptors and a reduction in PGE2 levels. No significant effects were found for a2-AR. Moreover, the rats that received the plant extract demonstrated similar responses to the positive control group.

Conclusions:

Arbutus andrachne can be a good candidate for treating inflammation and pyrexia and should be further investigated.
PI Controller Based Switching Reluctance Motor Drives using Smart Bacterial Foraging Algorithm
Authors: Akkara Stephy , T Jarin
Published: March 2022

Optimization algorithms are commonly used in the industry. The optimization strategy, if key elements are ignored, can quickly render the solution unfeasible. As a result, various optimization strategies are applied at all aspects of the industry level. The switched reluctance motor is the most affordable of all motor types. The high torque density attribute of induction motors is one of the market's major drivers.  Switched reluctance motors are also employed in high-volume and high-starting torque appliances. The Smart Bacterial Foraging Algorithm (SBFA) mimics the chemotactic behavior of E. Coli bacteria for optimization purposes. This method is used to calculate the coefficient of a typical Proportion–Integration (PI) speed controller for SRM drives while accounting for torque ripple reduction. The results of the modeling and experiments reveal that the modified PI controller with SBFA performs better. The proposed optimization strategy results in increased performance when compared to regular BFA.

After nearly 30 years of development, service robot technology has made important achievements in the interdisciplinary aspects of machinery, information, materials, control, medicine, etc. These robot types have different shapes, and mainly in some are shaped based on application. Till today various structure are proposed which for the better analysis’s need to have the mathematical equation that can model the structure and later the behaviour of them after implementing the controlling strategy. The current paper discusses the various shape and applications of all available service robots and briefly summarizes the research progress of key points such as robot dynamics, robot types, and different dynamic models of the differential types of service robots. The current review study can be helpful as an initial node for all researchers in this topic and help them to have the better simulation and analyses. Besides the current research shows some application that can specify the service robot model over the application.
Projection of Real Mass Deformation Scenes – Intelligent Support

The paper analyses the process of post-mining displacements generated by underground mining. Innovative mathematical structures for the modeling of hazard field emission were developed as strong solutions to partial differential equations in R3+1. Moreover, a stochastic equation in L2(Ω) (probabilistic space) was defined and applied as a model that takes into account the randomness of the process. Monitoring of a mining area based on solutions in the GNSS technology and classical geodesy supports the analysis of topological transformations of a given subspace. The data was archived and stored in digital form and then analyzed in many ways. The quality of the representation (measurements and modeling) was estimated with the use of incremental statistics. Thus, obtained distributions of density function are not ranked as normal distribution. The performed analyses make it possible to predict the optimal scenarios for post-mining environmental hazards.
Open-air Museums – the Future of the Presentation of Spiritual and Architectural Heritage

The origins of “open-air museums” date back to the nineteenth century and from the very beginning were closely linked to efforts to capture, preserve and present folk culture. However, during the course of the twentieth century, especially in its later part, the concept of open-air museums began to expand. Open-air museums were founded that focused on urban, industrial and military environments, ecological issues, or on charting the life of prehistoric and ancient cultures. Along with this, the methodological concept for this specific type of institution saw some development, and the interdisciplinary approaches expanded in response, covering a wide range of humanities as well as natural sciences. Besides the academic approach, a social and community overlap is also required from these institutions. This article poses the question of how the concept of open-air museums can continue to develop and what direction the role of presenting cultural heritage in an open landscape could take in the future. The arguments herein are based on the philosophical and spiritual dimension of man’s dwelling in the world and his relationship to the landscape in which he lives. We believe that the future of open-air museums should, wherever possible, focus on the preservation of monuments in their historical context and especially in their natural links in terms of landscape, urbanism and architecture. To ensure this concept remains sustainable, it is necessary that these monuments be involved in the life of villages and communities, ideally also on the basis of cooperation between academia and local entities, which are usually villages or municipalities and citizens’ initiatives. Examples of such a direction can be seen in the founding and running of Rochus Park in the Uherské Hradiště region and in the concept of the association of villages called Mariánská zahrada in the Jičín region, both in the Czech Republic.
Cultural Heritage and Cultural Potential: The Use of Cultural Heritage on the Example of an Ethnographic Group
Authors: Lenovský Ladislav , Kurajda Lukáš

The formation and use of the cultural heritage and identity of local communities is a result of historical development and current opportunities and needs. Cultural heritage becomes a part of the cultural potential as a system. In Čajkov, the most representative village of the Slovak Chilejkar people, there is a system of using the established concept of local cultural heritage through cultural events (several of which are closely connected in terms of organisation and visitors) implemented by local human resources structured into local organisations and institutions, which are relatively diverse but have an internal logic. Some events have an old tradition; others originated and became “traditional” only a few years ago.
The outlined system existing in a municipality with less than 1000 inhabitants reflects the degree of functioning of the local community. It is conditioned by cohesion, hierarchy, the self-confidence of members and appropriate economic conditions. For seniors, besides routine and tradition, the essential activating element is the social dimension – being socially active means meeting others, spending time with peers and eliminating loneliness. It is also an important identity creator in the socialisation, education and especially the upbringing of children and youth.
