РОЛЬ СІМ’Ї У МОРАЛЬНОМУ ВИХОВАННІ ДІТЕЙ
Authors: Поліщук Ольга
Published: November 2021

У статті досліджується роль сім’ї в моральному вихованні дітей та розкрито особливості морального виховання. Обґрунтовано думку про те, що моральне виховання дуже важливе для повноцінного розвитку дитини. Моральне виховання дітей відбувається впродовж їхнього життя, і визначальне значення в становленні моральності дитини відіграють середовища, в якому вона розвивається і росте.

Автор доходить висновку, що навчити дитину моральних принципів – надзвичайно вагоме завдання для батьків. Сім’я - один з основних джерел морального виховання дітей. Правила поведінки, прийняті в сім’ї, дуже швидко засвоюються дитиною і сприймаються нею, як правила загальноприйнятої норми. Найперше завдання батьків полягає в тому, щоб допомогти дітям визначитися з об’єктами їхніх почуттів і зробити їх суспільно цінними. Почуття дозволяють людині відчути задоволення після зробленого правильного вчинку або змушують відчувати докори сумління, якщо моральні норми були порушені. Основа таких почуттів як раз і закладається в дитинстві, і завдання батьків допомогти в цьому своїй дитині. Обговорювати з нею моральні питання, допомогти сформувати систему моральних цінностей.

На основі вивчення психолого-педагогічної літератури встановлено, що розвиток моралі в дитини невіддільний від її соціального розвитку. Якщо з якихось причин дитина не має достатньо сформованих соціальних навичок, вона стає схильною до аморальної поведінки.
A Model for Creating a Common Health Promoting School Environment
Authors: Sokolova SB
Published: November 2021

Introduction: Deterioration of students’ health, the absence of scientific substantiation of consistent actions, key directions and indicators of work of comprehensive schools in the sphere of health protection of participants in the educational process determine the purpose of the study to give a rationale for the algorithm and model of creating a common health promoting school environment.
Materials and methods: The study was carried out in four directions: 1) study of health promoting activities in modern schools; 2) analysis of indicators of socio-psychological climate of schools; 3) study of the lifestyle, work pressure and schedule, health status and psychological well-being of teachers; and 4) study of foreign instruments for assessing health promotion interventions at schools. The objects of the study included comprehensive schools, schoolchildren, teachers, and foreign instruments for assessing health promotion interventions at schools. The research materials were statistically processed by nonparametric methods using Statistica 13.3 software.
Results: Most of the surveyed Russian schools are at the initial stages of developing health promoting frameworks. Based on the expert statistical analysis of health promotion interventions of Russian schools at different levels of development and having different achievements in the field of preventive activities, effective directions and specific indicators for assessing results at each stage of creating a common preventive environment in a comprehensive school were identified and substantiated.
Conclusions: An algorithm and a model of a common preventive school environment consisting of seven components have been developed and a system for its monitoring by key indicators, the subjects and objects of which are students, their parents and teachers, has been substantiated. The results of health promoting activities at school include health improvement in schoolchildren and teachers, their emotional well-being, a decreased prevalence of behavioral risk factors, and improvement of knowledge and skills in relation to health and of the academic performance of students.

Published: November 2021

Background: In contemporary conditions of digital transformation of education, the medical community, teachers, and parents are concerned about health effects of electronic learning tools in children. The emergence of new types of digital tools necessitates studies of related fatigue of schoolchildren in the dynamics of learning. A questionnaire-based survey of pupils aimed to establish their main complaints attributed to the use interactive panels, the most common type of educational boards in the classroom, helps identify and analyze weaknesses from the point of view of health maintenance in organization of the educational process.
Objective: To study specific health effects of interactive panels used in the classroom in fifth-year pupils.
Materials and methods: We conducted a questionnaire-based survey of 130 schoolchildren aged 11 years to establish their self-rated health, visual functions, risk factors and educational experience related to the use of interactive displays. Data processing was carried out using nonparametric methods of statistical analysis; relative risk values were established according to the rules of evidence-based medicine.
Results: Some pupils, especially those with vision impairment, had complaints indicative of general and visual fatigue following the exposure to interactive panels. Inappropriate or excessive use of the interactive display in the classroom increased the frequency of such complaints.
Conclusion: The reported adverse factors including bright light from the display, small and fuzzy image, rising temperature in the classroom, etc., defined preventive measures to be implemented for ensuring safe learning conditions.
Effects of B2O3doping on the dielectric and piezoelectric properties of (K,Na,Li)NbO3–BaZrO3–(Bi,Na)TiO3ceramics
Authors: Wei Nan , Karaki Tomoaki , Fujii Tadashi
Published: November 2021

(K,Na,Li)NbO3–BaZrO3–(Bi,Na)TiO3–xB2O3(KNLN–BZ–BNT–xB2O3) ceramics were prepared by the conventional solid-state reaction method. The effects of B2O3content on dielectric and piezoelectric properties of KNLN–BZ–BNT ceramics were studied. Based on identification by X-ray diffraction, all samples showed a two-phase coexistence zone consisting of rhombohedral and tetragonal phases. It was found that B2O3addition is effective both for obtaining a dense structure and for increasing the grain size of KNLN–BZ–BNT ceramics sintered at a low temperature. For ceramics withx = 0.5 wt%, the sintering temperature was observed to reduce from 1200 °C to 940 °C, while the samples maintained a high relative density around 97%. Because of the high densification and large grain size, the dielectric and piezoelectric properties improved. As a result, the ceramics withx = 0.5 wt% sintered at 940 °C exhibited good properties ofd33 = 197 pC N–1,kp = 0.29, tanδ = 0.029 andεr = 1889, together with a Curie temperature (Tc) of 222 °C.
Stable Regime, Historiography and Truth Commissions
Authors: Taj Farhat
Published: November 2021

This article discusses the Pashtun Tahafuz Movement's (PTM) demand for establishing a Truth and Reconciliation Commission (TRC) to facilitate the right to truth of victims of the war on terror in Pakistan. It highlights the tension among the right to truth, geopolitical considerations, and historiography in pursuit of transitional justice under a stable regime. It argues that Pakistan is not likely to establish a TRC due to its geopolitical considerations vis-a-vis Afghanistan. It, however, also underscores that PTM as a pressure group could contribute greatly to realising several human rights based right claims of the war victims, if it disengages itself from the anti-Pakistan Afghan diaspora.
Decennial geomorphic transport from archived time series digital elevation models: a cookbook for tropical and alpine environments
Authors: Lucas Antoine , Gayer Eric
Published: November 2021

On the seasonal time scale, for accessible locations
and when manpower is available, direct observations and field
survey are the most useful and standard approaches. However
very limited studies have been conducted on direct observation
at the decennial to century time-scale due to observational
constrains. Here, we present an open and reproducible pipeline
based on historical aerial images (up to 70 yrs time span)
that includes sensor calibration, dense matching and elevation
reconstruction over two areas of interest that represent pristine
examples for tropical and alpine environments. The Remparts
Canyon and Langevin River in Reunion Island, and the Bossons
glacier in the French Alps share a limited accessibility (in time
and space) that can be overcome only from remote-sensing. We
reach a metric to sub-metric resolution close to the nominal
images spatial sampling. This provides elevation time series with
a better resolution to most recent satellite images such as Pleiades
over decennial time period.

Published: November 2021

Protection of fruit crops from pests is one of the most important tasks of gardening. In turn, the use of protective measures has both positive and negative sides, which makes the issue of improving their effectiveness one of the main ones. Having data on the estimated number of pests and the dates of the beginning of their development phases, it is possible to increase efficiency by choosing the optimal exposure measure and drawing up a more accurate schedule of protective measures. One way to determine such parameters is to use simulation. The article presents one of the approaches to constructing a mathematical model of the insect development process, which is used to build a software simulation model that allows to increase the effectiveness of protective measures of fruit crops. The article describes what is the essence of the modeled process. A mathematical model and methods for determining its parameters are presented. The required initial data for modeling are defined.
ПОНЯТТЯ ТА ОСОБЛИВОСТІ ЛІСУ ЯК ОСНОВНОГО РЕСУРСУ НАВКОЛИШНЬОГО ПРИРОДНЬОГО СЕРЕДОВИЩА
Authors: Соцький А. М.
Published: November 2021

Ліс є ресурсно-сировинним та рослинно-ягідним постачальником, що потребує захисту держави та урегулювання його використання. Саме ці та багато інших питань лежать у правовій площині, і лісові відносини урегульовується нормами права. Зазначено, що біологічні, хімічні та інші характеристики природних об’єктів не завжди автома- тично приймаються юриспруденцією, право формує поняття природних об’єктів, керуючись своїми критеріями, і поняття ці можуть збігатися, проте можуть і відрізнятись. Саме тому не варто зако- нодавцю уникати правових колізій за допомогою використання схожих термінів, оскільки ця практика сприяє виникненню ще більшої плутанини і виникненню нових правових колізій. Поняття «земельна ділянка» та «земля» в більшості випадків охоплюють не лише простір над та під земною поверхнею, але й розташований у межах цього простору ґрунтовий покрив. Водночас, можливі ситуації, коли терміни «земельна ділянка», «земля» не будуть охоплювати ґрунт. У випадку, коли ґрунтовий покрив буде вилучено із природного середовища, тобто ґрунт перестане утворю- вати ґрунтовий покрив і буде поміщений, наприклад, у горщик із квіткою, він не буде охоплюватися ні поняттям «земля», ні «земельна ділянка», і відносини, об’єктом яких буде ґрунт у горщику, не будуть належати до предмету земельного права. Зазначено, що ліс – це природний, відтворюваний об’єкт природи, елемент екологічної системи, що складається з дерев, чагарників, іншої лісової рослинності, що зростає на землі; джерело одержання деревини та іншої лісової продукції, він виконує кліматорегулюючі, захисні, водоохоронні, санітарно- гігієнічні, оздоровчі, рекреаційні, естетичні, виховні та інші функції, які впливають одна на одну та на довкілля. Ліс як об’єкт природи має такі ознаки: об’єкт рослинного світу, зареєстрований у державних лісо- облікових документах як ліс, об’єкт власності, управління, використання та охорони; біологічна, біо- фізична, природна і кібернетична, економічна система; відтворюваний об’єкт природи; складається з деревно-чагарникової та трав’янистої рослинності, що зростає на землі; виробляє різноманітні сиро- винні ресурси; впливає на навколишнє природне середовище.
РЕАЛІЗАЦІЯ ПРИНЦИПУ ПРАВОВОЇ ВИЗНАЧЕНОСТІ КРІЗЬ ПРИЗМУ ЗАХИСТУ КОНСТИТУЦІЙНИХ ПРАВ І СВОБОД ЛЮДИНИ ТА ГРОМАДЯНИНА
Authors: Подорожна Т. С. , Котуха О. С.
Published: November 2021

У статті досліджено принцип правової визначеності, його реалізацію у процесі захисту прав і свобод людини та громадянина. Зазначено, що в широкому розумінні принцип правової визначеності є сукупністю вимог до організації та функціонування правової системи з метою забезпечення стабільного правового становища людини шляхом удосконалення процесів правотворчості і правозастосування. При цьому для сучасної конституційної держави найвищим досягненням має стати довіра громадян до самої держави та її інститутів. Така довіра може ґрунтуватися тільки на гармонійній взаємодії правової визначеності чинного законодав- ства та аналогічної його дії на практиці. Дотримання принципу правової визначеності чітко позна- чає межі діяльності державної влади, максимально домагається прозорості у відносинах держави й людини, тим самим забезпечуючи дотримання прав і свобод людини та громадянина. Наголошено на тому, що в основі принципу юридичної визначеності, як одного з істотних елементів принципу верхо- венства права, лежить відоме з римського права положення res judicata (лат. «вирішена справа»), відповідно до якого остаточне рішення правомочного суду, яке вступило в силу, є обов’язковим для сторін і не може переглядатися. Зроблено висновок про те, що ідея та поняття «правова визначе- ність» є досить складною, багатогранною, різноаспектною категорією як для правової доктрини, так і для юридичної практики. Правова визначеність є універсальним принципом у всіх сферах юри- дичної діяльності. Це постає з того, що, по-перше, у законотворчій сфері правова визначеність є ключовим критерієм якості та основною метою цього виду діяльності; по-друге, правова визначе- ність є найважливішим інструментом і засобом у процесі реалізації конституційного контролю орга- нами правосуддя. Вищий судовий орган конституційного контролю неодноразово встановлював, що невизначеність норм права сама собою неконституційна, адже дає можливість правозастосовникові зловживати своїм становищем, по-різному тлумачити норми права залежно від власного інтересу, ставить суб’єктів права в нерівні умови.
ДИСЦИПЛІНАРНА ВІДПОВІДАЛЬНІСТЬ ПРАЦІВНИКА НАЦІОНАЛЬНОЇ ПОЛІЦІЇ УКРАЇНИ
Authors: Мух К. Б.
Published: November 2021

Дисциплінарна відповідальність працівників поліції розвивається динамічно, але досить безсистемно, що не дозволяє в належній мірі використовувати потенціал даного виду юридичної від- повідальності як важливого засобу підтримки службової дисципліни в апараті державних органів, створення адміністративно-правових засобів попередження та припинення правопорушень як пра- цівників, так і роботодавців, забезпечення прав і законних інтересів працівників Національної поліції тощо. Аналіз чинного законодавства України дозволяє зробити висновок, що існуюча модель дисциплінар- ної відповідальності поліцейських знаходиться під сильним впливом трудового права з притаманною йому диспозитивністю, що суперечить адміністративно-правовій концепції побудови дисциплінар- ного законодавства і передбачає широке застосування методу імперативного регулювання державно- службових відносин. Це, на наш погляд, і зумовлює вкрай низький ефект від застосування до поліцей- ських заходів дисциплінарної відповідальності та не дозволяє забезпечити належний рівень виконання дисципліни в державному апараті. На відміну від інших видів юридичної відповідальності, де санкція за вчинене правопорушення є невідворотною, вирішення питання про невідворотність покарання за вчинення дисциплінарного про- ступку знаходиться у відомстві посадової особи, наділеної дисциплінарно-юрисдикційними повнова- женнями. При цьому, як показують дані правозастосовної практики, надане йому «право-обов’язок» застосувати дисциплінарне стягнення часто залишається нереалізованим. У статті ставиться завдання розглянути та проаналізувати поняття, зміст та сутність дис- циплінарної відповідальності поліцейського, а також визначити її функції, за допомогою яких здій- снюється правомірний характер виконання заходів покарання за вчинення проступку працівником. Висновки цієї статті дозволять у найбільшій мірі розібратися в понятійному апараті дисциплінарної відповідальності саме такого специфічного суб’єкту трудових правовідносин, як працівники Націо- нальної поліції України.

The aim of the present investigation was to examine the haematological profile and oxidative stress before and after disbudding in calves. The study was carried out at Livestock Farm Complex, College of Veterinary Science and Animal Husbandry, ANDUAT, Kumarganj, Ayodhya and nearby villages. Twenty four cattle calves were utilized to study haematological parameters that are Haemoglobin (Hb (gm/dl), Neutrophil (%), Basophil (%), PCV (%), Lymphocyte (%), Monocyte (%), TLC (103/ µl), Eosinophil (%), N/L ratio) and oxidative stress before and after disbudding in to four groups viz. control (T0), lignocaine (TL), tremadol (TT) and lignocaine+tremadol (TL-T). After medication calves were disbudded by hot iron method. The blood samples were collected for haematological parameters & for estimation of LPO (lipid peroxides) as per method described by [1] just before (0h) and after disbudding on 6h, 24h and 72h. The results showed that, at 24h, T0 group showed significantly lowest Hb (10.66±0.49%) which was statistically similar to TT and TL-T groups. At 0h, 6h and 72h means of PCV% were significantly different among treatment groups. The lowest lymphocytes (64.00±1.00) was observed in TT group at 6h. The T0 group showed significantly lowest basophil (0.00±0.00) which was statistically similar to TT and TL-T groups but significantly different from TL group at 6h. At the same interval, T0 group showed significantly lowest monocytes (4.66±0.61) which was significantly different with TL, TT and TL-T groups. At 6h, T0 group showed significantly lowest N/ L ratio (0.15±0.01) which was statistically similar to TT and TL-T groups but significantly different from TL group. At 0h, 6h and 24h LPO was significantly different among groups. At 0h, T0 group showed significantly highest (106.59±0.63) which was significantly different from TL, TT and TL-T groups. It may be concluded that no significant difference was observed in eosinophil%, TLC, neutrophil% and monocyte% counts between control and treatment groups. However, Hb%, basophil%, PCV% and lymphocyte% were significantly different between control and treatment groups. N/L ratio was significant only at 6h. Most of the cases TL-T group showed comparatively better performance. At 0h, 6h and 24h LPO was significantly different among groups. At 0h, T0 group showed significantly highest (106.59±0.63) which was significantly different from TL, TT and TL-T groups.

The disability of lower limbs is one of the major problems facing human lives. In order to restore the missing functionality and aesthetic feature of the amputee's locomotion, finding the optimal design of the human lower limb knee prosthesis is crucial. This paper focuses the design optimization of a four bar knee mechanism capable to reproduce the complex flexion/extension knee joint motion in the sagittal plane with variable instantaneous center of rotation positions. Thus an optimization approach with appropriate constraints is formulated in order to consider the degree of compatibility between the instantaneous center of rotation trajectories of the human reference knee joint and the four bar knee mechanism. To solve this high nonlinear optimization problem, an algorithm based on multi-objective modified imperialist competitive method is proposed where all the constraints are managed with the penalty method. The results obtained by the multi-objective modified imperialist competitive method showed the capability to reach a small tracking error. The obtained results prove the effectiveness of the proposed optimization approach for the optimal synthesis of the four bar knee mechanism, compared with other literature techniques.

Companies follow their objectives with some critical success factors (CSF), and they know their bottlenecks and strong points. This provides decision support for them, but this method ignores overall performance and ranking issues. In this study, a comprehensive methodology is recommended to find out an effective solution to the performance evaluation problem for making strategic performance management. Two methods are used from different areas as a framework. To select the higher-performing departments, Data Envelopment Analyses (DEA) is used as a linear programming-based main method. Moreover, a Multi-Criteria Decision Making (MCDM) method is proposed, Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE), to increase the discrimination power of DEA and eliminate undesirable results because of determining weight bounds. These two methods are combined, and a comprehensive solution model is presented in the study. In the end, a case study is given for a real-life example, an integrated DEA-PROMETHEE method is applied to the case. When the case results are examined, the proposed model produces more logical weight values and better results.

During a national lock down and a curfew, most of the concrete projects are left without curing and therefore, the elements of the building need strengthening. An effective way in strengthening is using Post-Tensioned Metal Straps (PTMS) which is a relatively new method. Therefore, in this study, the effectiveness of using PTMS is tested in strengthening cylinder samples without curing. For this purpose, 15 cylinders are cast and 12 of them are left without curing for 28 days. Three samples are tested without any strengthening and are used as control samples. The rest are strengthened using 1, 2, 3, and full layers of PTMS. To compare the strength of the cylinders, 3 cylinders of the same batch are prepared and cured for 28 days. It is proved that the compressive strength of the cylinders can increase by 39%, 57%, 84% and 125% if the samples are strengthened using 1, 2, 3, and full layers of PTMS. It is also found that the failure becomes ductile as the number of layers is increased.

This paper investigates free convection in a partially heated square cavity filled with alumina-water nanofluid. The investigation is carried out at the three-volume fraction of nanoparticles (0, 0.03, 0.05), two Prandtl numbers (2.66, 6), and constant Grashof number (105) with three shapes of insulating obstacles (Square, Circular, and Rectangular). The results show that the nanofluid volume fraction and Prandtl number significantly enhance the heat transfer. The user-defined function (UDF) is developed and computed to investigate the effect of nanoparticle diameter and its temperature-dependent viscosity on convection. The average Nusselt number (Nu) increased with the temperature-dependent viscosity model and by increasing the percentage concentration of the nanoparticles. For all obstacle shapes, the thermal performance improved with increase in the nano-particle diameter.

Nous proposons dans cet article d'appliquer une méthode d'attribution au changement climatique, pour la canicule de juillet 2019 sur la France métropolitaine. Nous décrivons d'abord comment l'attribution est effectuée. Ensuite, nous montrons qu'aujourd'hui le risque d'occurrence de ce type de canicule a été multiplié par au moins 10 et qu'en 2040 il sera multiplié par au moins 20. De plus, nous analysons le changement de risque à la fin du siècle pour deux scénarios climatiques : dans le meilleur des cas, nous reviendrons à la situation actuelle en 2100 ; dans un cas défavorable, des canicules similaires à celle de 2019 produiront des températures d'au moins 43 °C sur la moitié de la France.

We propose in this article to apply a method of attribution to climate change for the French Metropolitan heat wave of July 2019. We first describe how the attribution is performed. Then, we show that currently the risk of occurrence of this type of heat wave has been multiplied by at least 10, that in 2040 it will be multiplied by at least 20. In addition, we analyze the change in risk at the end of the century for two climate scenarios: in the best case we return to the current situation in 2100, in an unfavourable case heat waves similar to the one in 2019 will produce temperatures of at least 43 °C over half of France.
Early and Progressive Cognitive Disorder Imposes CADASIL Syndrome in the Diagnostic Assumption
Authors: Fortofoiu Mircea-Catalin
Published: November 2021

The case presented is a diagnostic challenge considering the family and medical history of the 65-year-old patient with a family history of migraine depression, emotional lability, and gait disorders manifested at his grandmother, his mother, and his sister. After multiple hospitalizations for the described symptoms and multiple treatments with questionable results, the diagnosis was imposed by the appearance described by brain MRI to which were added the data from the patient's family and personal history. Of course, a full confirmation of the diagnosis would have required skin biopsies and genetic testing that the patient refused to perform. However, due to its peculiarities, the presented case tries to offer a diagnostic orientation path for practitioners in situations where previous diagnoses and treatments are not sufficiently conclusive either due to the impossibility of performing specific tests at that time or either because of the patient's indifference to his state of health.

In a real Hilbert space $H$ we consider the following singularly perturbed Cauchy problem ... We study the behavior of solutions $u_{\varepsilon\delta}$ in two different cases: $\varepsilon\to 0$ and $\delta \geq \delta_0>0;$ $\varepsilon\to 0$ and $\delta \to 0,$ relative to solution to the corresponding unperturbed problem.We obtain some {\it a priori} estimates of solutions to the perturbed problem, which are uniform with respect to parameters, and a relationship between solutions to both problems. We establish that the solution to the unperturbed problem has a singular behavior, relative to the parameters, in the neighbourhood of $t=0.$

In the real Sobolev space $H_0^1(\Omega)$ we consider the Cauchy-Dirichlet problem for sine-Gordon type equation with strongly elliptic operators and two small parameters. Using some {\it a priori} estimates of solutions to the perturbed problem and a relationship between solutions in the linear case, we establish convergence estimates for the difference of solutions to the perturbed and corresponding unperturbed problems. We obtain that the solution to the perturbed problem has a singular behavior, relative to the parameters, in the neighbourhood of $t=0.$

Transitive Avoidance Games on Boards of Odd Size
Authors: Gehnen Matthias , Triesch Eberhard
Published: November 2021

Avoidance (or misère) games are a type of positional games. Two players alternately claim points of a set $N$ (the `board' of the game). The game is determined by a family $L$ of subsets of $N$ and the following rule: The first player who claims every point of some set in $L$ loses the avoidance game. The game is called transitive if the group of all permutations of $N$ leaving $L$ invariant acts transitively on $N$. Johnson, Leader and Walters show that for a board size which is neither a prime number nor a power of two there are transitive avoidance games where the first player can force his win. For primes of size at least $17$, the corresponding problem remained open. We are going to close this gap and prove that for all primes $n$ of size at least $17$ there are also transitive avoidance games with board size $n$ where the first player can force his win.

Published: November 2021

As business events flourish in diverse markets, the emphasis on experience needs to be tempered with sustainable operations. Through interviews with exhibition events sector stakeholders, this research examines the adoption of green practices in the Chinese context. The study adopts
a stakeholder perspective to examine the multiple relationships that influence the choice and implementation of green practices in the exhibition events sector, examining motivations and barriers to the adoption of these practices. Leveraging on the regenerative paradigm, which positions sustainability
as an acceptable but insufficient course of action for a long-term future, the study delves into the sector's receptivity toward regenerative practices as a radical improvement of green practices. The findings suggest that the challenge to innovate in green practices into the realm of regeneration
is firmly considered a government-level directive. Moreover, there remains a lack of whole-of-place perspective in the current green practices, which is contrary to the regenerative paradigm. By extending the study beyond sustainability into regeneration, this research contributes to the literature
on event management and its environmental impacts, challenging the exhibition events sector to adopt green practices that not only mitigate but actively remediate their impacts on the world they operate in.

The future growth of the conference industry will depend on how well it understands the demographic trends influencing it. As members of Generation Z reach adulthood and become a target market for the conference industry, an understanding of their motivations, needs, and expectations
is crucial. To date, this topic has received limited research attention. Targeting Chinese students from Generation Z, this study used an online survey to examine their motivations for conference attendance and their expectations with regards to conference design. China is an emerging market
with huge conference potential. The key findings show that: 1) destination characteristics and educational and professional opportunities are important motivators for China's Generation Z to attend a conference; 2) edutainment, interactivity, short sessions, use of technology, and sustainability
practices are expected to be implemented into event design; and 3) face-to-face, website and e-mail are the preferred communication channels with the conference organizer and other conference participants. Although, for the most part, the characteristics of Generation Z in China seem to be
aligned with Generation Z elsewhere, in the conference sector context it is important to acknowledge and appreciate the country-specific nuances in Generation Z preferences, and conference organizers must acknowledge and adapt to these preferences. This research will assist the conference
industry to make necessary adjustments to existing products and services, and to identify new opportunities to develop products and services that will resonate with this new market.

Published: November 2021

The expansion of event majors in China is still unable to satisfy the demand of the fast-growing event industry. Keeping graduates in the event industry could help solve the labor shortage of the industry. However, existing literature has overlooked the influencing mechanism on Chinese event students' job pursuit intention. To address this research gap, the current study aims to investigate how career awareness affects Chinese event students' job pursuit intention. This research also examines the mediating effect of career satisfaction and the moderation effect of career self-efficacy. Based on the signaling theory and self-efficacy theory, the present study develops an integrated research model that includes career awareness, career satisfaction, career self-efficacy, and job pursuit intention. A total of 198 usable responses from 18 event undergraduate programs were collected in China. Results show that Chinese event students' career awareness positively associates with enhanced career satisfaction, which subsequently improves their intention to stay in the event industry. This effect is fully mediated by career satisfaction. Moreover, the current study demonstrates the moderating effect of career self-efficacy between career satisfaction and job pursuit intention.

Authors: Kc Birendra , Lapan Chantell , Ferreira Bruno , Morais Duarte B.
Published: November 2021

Microentrepreneurship has always been an important driving force of the tourism industry. However, until recently, this sector was mostly invisible and understudied. Microentrepreneurs are now becoming influential stakeholders due to new information technologies that make their offerings
easily accessible to a broader clientele and render their economic activity more transparent and taxable. There is a growing consensus that tourism microentrepreneurs can make destinations more competitive and equitable. Accordingly, there has been a surge of scholarship on tourism microentrepreneurship
to inform strategies and policies to fuel microentrepreneurial development and its integration with the formal tourism sector. The purpose of this conceptual article is threefold: first, to discuss the definition of tourism microentrepreneurship and commonly used theoretical conceptualizations,
as well as the evolution of research on tourism microentrepreneurship; second, to identify research gaps in the existing literature and propose avenues for future research; third, to serve as an introduction to a Special Section on Tourism Microentrepreneurship. In addition, we offer a set
of practical recommendations for destination managers and supporting organizations to develop and nurture networks of microentrepreneurs, and to identify suitable and rewarding microentrepreneurial opportunities in the tourism business ecosystem.

The aim of this study was to evaluate the yield variability of spring barley families grown at the Nagradowice Plant Breeding Station of Poznan Plant Breeding against other families studied in years 2017‒2018 in Team Breeding Experiments. Research material included 250 spring barley families cultivated in 2017 and 2018 in 6 locations. Selection of spring barley families for preliminary experiments was based on synthesis of results obtained in inter-plant experiments established in 2016 and 2017 in 5 locations. Combined (due to location) analysis of variance for experimental data was performed for each year and each series of experiments separately. Best Weighted Linear Unbiased Estimators (BWLUE) for the effects of individual sources of variation were included in ANOVA model. Significant effect of location on mean yield was observed in each research year and each series of experiments. Crucial differences were also observed between tested varieties and breeding lines. Moreover, significant interaction between locations and varieties or breeding families was also observed. Self-organising map (SOM) was applied to develop multivariable characteristic of tested families and cultivars of spring barley. Analyses results, i.e. ranking of BWLUE effects as well as SOM segmentation revealed seven breading lines from Breeding Station Nagradowice, which may be considered for further breeding process.

Published: November 2021

The present study aimed to enhance the dissolution rate, therefore bioavailability, of famotidine (FMT) using its solid dispersions (SDs) with polyvinyl pyrrolidone (PVP)-K 30, milk powder, and inulin, both in-vitro and in-vivo. The study was also aimed to compare the effect of different amorphous polymers in enhancing the dissolution rate of FMT. The SDs were prepared with a 1:4 weight ratio by a solvent evaporation technique. Evaluation of the properties of the SDs was performed using dissolution, Fourier-transform infrared (FTIR) spectroscopy, and X-ray diffraction (XRD) studies. The SDs of FMT exhibited an enhanced dissolution rate. The FTIR spectroscopic studies showed the stability of FMT and the absence of well-defined drug excipient interaction. The XRD studies indicated the amorphous state of FMT in SDs. The drug release rate of all SDs formulation was found to be greater than the pure drug. Within one hour of dissolution studies, 99.43%, 92.5%, and 58.93% drug release were obtained, respectively, for PVP K-30, milk powder, and inulin. The first two were showing significantly higher release. SDs were also studied for bioavailability studies in-vivo in rats, which confirms that the SDs prepared by PVP K-30 and milk powder significantly enhancing the bioavailability of FMT. The maximum concentration of 15.05±2.45 μg/ml was achieved in 2 hours, and the area under the curve was found to be 33.78±7.3 μg. hour/ml. Therefore, the study results conclude that SDs of the FMT prepared by PVP K-30 successfully increases the dissolution and in-vivo bioavailability.

Published: November 2021

У статті представлено підходи вивчення міжособистісних стосунків в теоріях малої групи, соціальної ідентичності та контроля впливу. Розглядається як взаємовплив людей в малих соціальних групах формує думки, поведінку і міжособистісні взаємини. Вивчаються узагальнені механізми, які лежать в основі розвитку довіри, статусних ієрархій, соціальної перцепції. Включеність осіб з порушеннями слуху до простору суспільних відносин виявляє її соціально-значущі риси, які спонукають до певного ставлення до людей інших соціальних груп, членів громадянської спільноти та до групової діяльності. Людина з порушеннями слуху стає повноцінним членом громадянського суспільства через власне оволодіння певними цінностями та нормами різних соціальних груп, способами взаємодії та комунікації з іншими. Спостерігається своєрідність розуміння «образу світу» людьми з порушеннями слуху, що впливає на їхні особливості встановлення міжособистісних контактів.

The authors of the article emphasize the need to form an effective system of higher education that would meet national interests and global development trends, provide training, as well as equal rights and opportunities for all actors in the educational process, including people with special educational needs. After all, the main goal of inclusive higher education is not only to eliminate barriers to access of students with special educational needs to the development of their natural potential, but also to enable them to achieve maximum independence, competence, competitiveness as necessary qualities and prerequisites for effective self-realization. It is proved that the effectiveness of the process of optimization of education and upbringing of students with special needs in higher education institutions depends on a set of organizational and pedagogical aspects. The first organizational and pedagogical aspect is the formation of a high level of readiness of teachers to carry out activities aimed at optimizing the teaching and education of students with special needs in higher education institutions. The second aspect of optimizing the education and upbringing of students with special needs is the development and implementation of a program of full inclusion of people with special educational needs in the educational process of higher education institutions. It provides primarily semantic and methodological support of this process on the basis of a holistic system approach. The third aspect optimization of education and upbringing of students with special needs is the formation of the educational space of higher education institution tolerant to the inclusion of people with special educational needs. The fourth organizational and pedagogical aspect of optimizing the education and upbringing of students with special needs in higher education institutions is defined - pedagogical monitoring of the relevant process.
