Derivation OF STIFFNESS Matrix for A general Two Dimensional Curved Element in General Global Coordinates System
Authors: Ahmed Balqees Abdul Wahid , Al-Janabi Mus’ab Aied Q.
Published: June 2024

In present paper, the derivation of stiffness matrix for a general two dimensional curved element in the global coordinates system is presented. The derivation depends on the assumption that any curved in-plane element can be approximated by a specified curve in polar coordinates. The polar curve assumed in this polar depends on some variables that enable it to represent any two dimensional curved element. The derivation process accompanied by complex integrals which are evaluated by using (Gaussian Quadrature) method of numerical integration. One numerical example is presented to verify the accuracy and efficiency of the derived stiffness matrix. Very good agreement is obtained between the results of the derived stiffness matrix and the results of the exact model.
Testing the Effects of Personality-Related Beliefs on Micro-PK
Authors: Jakob Marissa-Julia , Dechamps Moritz , Maier Markus
Published: June 2024

Objective.This preregistered study investigates mind-matter interactions by testing observer effects on quantum random number generator (QRNG) outcomes mediated by implicit intentions. Methods. We evaluated participants' personality traits (PTs), and presented them with goal-related or neutral stimuli based on QRNG outputs. We predicted deviations from chance, with high PT scorers expected to observe more PT-related sentences. We conducted three micro-psychokinesis (micro-PK) experiments for Cluster C's PTs: dependent, avoidant, and obsessive-compulsive. Results. The results revealed strong evidence (Bayes Factor > 10) for a micro-PK effect in the dependent PT group, with high scorers observing more sentences addressing their concerns than expected by chance. We did not find strong evidence for the other PT groups or low scorers. Conclusion. These findings suggest that intentional observation biases QRNG outcomes related to individuals' implicit concerns, potentially leading to self-fulfilling prophecies. The study's implications are discussed within the Unus Mundus model and the Model of Pragmatic Information.

Published: June 2024

In this issue of JAEX, Jakob et al. (2024) report results from an experiment to test whether an implicit psychokinetic effect related to unconscious intention can alter the outcome of quantum events. The experiment is well conceived and executed. However, the claim of evidence to support the experimental hypothesis is undermined by errors of analysis and of omission. Some are not obvious and require a careful reading to discern. I explain the nature of the mistakes, where and how they arise, and the consequences for the inferences the authors’ draw. I emphasize that a helpful way to detect such problems is by following the chain of inference in experimental reports. Editors, reviewers, and particularly authors can protect the integrity of the scientific literature by reading carefully in this way.

History of human capital in economic theory
Authors: Astanakulov Olim , Arsahanova Zina , Surilov Meir , Gachaev Ahmed
Published: June 2024

The neoliberal paradigm has put forward a conceptual and epistemological shift from neoclassical economics, suggesting that economic activity should not be the study of various mechanisms such as consumption, production and investment, but rather should be the study of interchangeable options. These interchangeable options will function within a spontaneous order that goes beyond the human will and must be maintained to ensure optimal and efficient allocation of limited resources. Moreover, based on the theory of human interests, it has been postulated that human capital is a key factor in economic growth and income growth throughout the developed world.

Published: June 2024

The article describes the application of the project management method in the US industry in the 1970s. The project management method was used in industry in various forms and was designated by such terms as the organization of work on the project, project coordination and interconnection of developments. The project method of management organization, characterized by a certain sequence of work, a set of tools used, as well as a certain distribution of responsibility, requires the appointment of one person responsible for the implementation of the project, the establishment of centralized control over information, and allows for the possibility of decentralized implementation of specialized functions.

Published: June 2024

The modem concept of cluster organization of the economy is developing at the intersection of several areas of economic theory. According to authors, the innovation cluster is a form of institutionalization of economic interests interconnected by a certain corporate culture of interaction not only of companies and organizations that form an integrated structure, but also of external actors within the framework of using the potential of innovative development of regions. The authors’ definition of the category “innovation cluster” actualizes the issue of forming a set of actions of the state and business regarding the full use of competitive advantages of territories based on the balance of interests and principles of smart specialization in the regions.
The daily experience of hunger in UK females with and without food insecurity
Authors: Neal Courtney , Pepper Gillian V , Shannon Oliver , Allen Caroline , Bateson Melissa , Nettle Daniel
Published: June 2024

Food insecurity (FI) is associated with obesity in women in high-income countries, but causal mechanisms remain unclear. FI is often assumed to lead to increased levels of hunger. However, quantitative evidence describing daily experiences of hunger in FI is lacking. Our pre-registered study used ecological momentary assessment to capture experiences of hunger in two groups of UK-based women: those experiencing FI (N = 143) and those experiencing food security (FS; N = 149). Participants self-reported hunger hourly (0900-2100) for one week (Monday-Sunday). There was no difference between groups in mean hunger (t(290) = 0.17, p = .866, d = 0.02) nor within-day standard deviation in hunger (t(290) = 1.31, p = .193, d = 0.15). However, both quantities fluctuated more from day to day in the FI group. Compared to the FS group, women in the FI group had a larger day-to-day variation in mean hunger (t(284) = 2.43, p = .016, d = 0.29) and a larger day-to-day variation in the within-day standard deviation of hunger (t(284) = 2.90, p = .004, d = 0.34). These findings suggest that experiences of hunger are less stable in those experiencing FI, likely reflecting the environmental uncertainty in access to food associated with FI and more variable meal timing. Temporal irregularity in hunger may have downstream consequences for weight status and health outcomes, given hunger’s potent psychological influence on health behaviour.
Digital Tools to Mitigate Climate Change: A Scoping Review
Authors: Webster Richard J , Harrison Mary-Ann , Zitikyte Gabriele
Published: June 2024

Decision makers around the world are announcing climate targets, but often assume that future technologies will make their decarbonisation promises of today achievable tomorrow. Concerningly, the IPCC states that current technologies are insufficient to address the climate crises. Digital tools (e.g., software, phone apps, dashboards) provide an interesting microcosm to investigate the pace of emerging technologies, as they are rapidly developed, easily scaled, and leverage analytics; yet little is known about digital tools for climate action. This scoping review aims to i) identify digital tools for climate mitigation, ii) assess their pace of innovation, and iii) perform a gap analysis. We identified 352 digital tools for climate mitigation. This repository of tools has particular value as 72% of these digital tools were found to be open source. A novel statistical analysis was used to determine the pace of innovation and assess the maturity of climate mitigation digital technologies. Encouragingly, digital tools for climate mitigation are emerging at an annual rate of 19% (95% CI: 16- 22%), with open-source solutions driving this exponential growth. This snowballing growth of climate mitigation digital innovations might yield disruptive solutions for emissions savings and is optimistic news for tackling the climate crisis.
e-fold cross-validation: A computing and energy-efficient alternative to k-fold cross-validation with adaptive folds
Authors: Beel Joeran , Wegmeth Lukas , Vente Tobias
Published: June 2024

We present the idea of "e-fold" cross-validation. The core idea is that e is chosen ’intelligently’ and individually for each experiment and dataset. This contrasts a static k chosen by gut feeling and past experiences on what k is ’typically’ good. Our goal for e-fold cross-validation is that e is as small as possible so as not to waste timeand energy and not to create unnecessary CO2 emissions but large enough to provide (near) optimal performance.
The Ideal Ultimate Frisbee Throw: Grid search for the perfect pass
Authors: Ding Anthony , de Oliveira Zanini Plinio Rodrigues
Published: June 2024

In 1968, the idea of Ultimate Frisbee was introduced by Joel Silver. In this short time, it has slowly risen to popularity, but not to the level of other, more established sports. As such, the depth of research that sports like basketball or football athletes can benefit from are far greater than that of ultimate frisbee players. This study aims to assist in remedying that, and answered a central question: What would the ideal short-to-mid range pass look like in Ultimate Frisbee? Throws were simulated and given a rating, a single quantitative measure of the quality of the throw. Since this area has not been investigated in too much depth, this study used broad ranges for initial values of speed, pitch, and spin speed. This work provides a methodology for the analysis of frisbee throws, setting a foundation for future studies, which may look into more specific parameters and complex factors.

Indiscriminate and imprecise use of penalty constants can lead to substantial computational problems and consequently erroneous conclusions and deductions .This paper viewthis, with utmost seriousness and thus establish an optimal penalty constant that optimizes theminimization of the cost functional z,while solving discrete optimal control problems usingextended conjugate gradient method (ECGM). I employed some measures that examine optimal control of dynamic processes that can be described by Differential Algebraic Equations (DAEs) that entails integer restriction on some or all of the control functions. I established the construction of an optimal penalty constant which can be employed in the extended conjugate gradient method algorithm for discrete optimal control regulator problems. Comparative results emanating from the use of different penalty constants/algorithms on some problems are given. The obtained numerical results reveal that the proposed optimal penalty constant expression is efficient.
Acceptance and motivational effect of AI-driven feedback in the workplace: An experimental study with direct replication
Authors: Hein Ilka , Cecil Julia , Lermer Eva
Published: June 2024

Artificial intelligence (AI) is increasingly taking over leadership tasks in companies, including the provision of feedback. However, the effect of AI-driven feedback on employees and its theoretical foundations are poorly understood. We aimed to close this research gap by comparing perceptions of AI and human feedback based on construal level theory and the feedback process model. Using these theories, our objective was also to investigate the moderating role of feedback valence and the mediating effect of social distance. A 2 × 2 between-subjects design was applied to manipulate feedback source (human vs. AI) and valence (negative vs. positive) via vignettes. In a preregistered experimental study (S1) and subsequent direct replication (S2), responses from NS1 = 263 and NS2 = 449 participants were studied who completed a German online questionnaire asking for feedback acceptance, performance motivation, social distance, acceptance of the feedback source itself, and intention to seek further feedback. Regression analyses showed that AI feedback was rated as less accurate and led to lower performance motivation, acceptance of the feedback provider, and intention to seek further feedback. These effects were mediated by perceived social distance. Moreover, for feedback acceptance and performance motivation, the differences were only found for positive but not for negative feedback in the first study. This implies that AI feedback may not inherently be perceived as more negatively than human feedback as it depends on the feedback's valence. Furthermore, the mediation effects indicate that the shown negative evaluations of the AI can be explained by higher social distance and that increased social closeness to feedback providers may improve appraisals of them and of their feedback. Theoretical contributions of the studies and implications for the use of AI for providing feedback in the workplace are discussed, emphasizing the influence of effects related to construal level theory.

Published: June 2024

Strontium isotope ratios (87Sr/86Sr) of incrementally grown tissues have been used to study animal movement/migration. Despite growing interest in this tool, questions remain regarding how different dental tissues preserve the same 87Sr/86Sr input signal, and how different biological processes and sampling methods influence measured enamel 87Sr/86Sr. We collected 87Sr/86Sr data from tusk dentine and molar enamel of Misha, a zoo elephant with known movement history, using in situ laser ablation (LA-ICP-MS) mapping, conventional drilling, and micromilling techniques. We compared 87Sr/86Sr data from different substrates to evaluate the influence of turnover, tissue type, and sampling methods. Our LA-ICP-MS analysis showed a remarkable 87Sr/86Sr geometry consistent with enamel apposition. Enamel maturation affects 87Sr/86Sr primarily in the outer enamel. Conventional drilling and micromilling produced attenuated 87Sr/86Sr records due to enamel maturation and sample averaging. Caution should be taken when interpreting 87Sr/86Sr data from conventionally drilled enamel, which may bias reconstructions of movement/migration. Our results show that LA-ICP-MS of the innermost enamel with associated dental growth measurements can best recover the primary 87Sr/86Sr turnover history. However, biological turnover of 87Sr/86Sr is still the primary source of input signal attenuation and should be accounted for. We recommend a micro-sampling and inverse modeling workflow which we demonstrate using Misha’s tusk and enamel data. While a broader application of this approach would benefit from more experiments, it can facilitate quantitative interpretations of movement/migration histories and help answer questions of individual life history such as human/animal seasonal subsistence and reproductive patterns.

Published: June 2024

Suicidal thoughts and behaviours (STBs) are more common among transgender and non-binary (TGNB) people relative to the general population. Nonetheless, research on correlates and predictors of STBs among TGNB people is lacking. This study used a mixed-methods design to examine whether negative healthcare experiences (NHEs) concurrently and prospectively predicted suicide ideation (SI) among 182 TGNB adults aged 18-55 (M=25.64, SD=6.63). Participants could complete the study online worldwide, although 84% resided in North America. At baseline, participants completed questionnaire measures of NHEs, SI, depression symptoms, social support and TGNB community connectedness. The NHE questionnaire included open textboxes and responses were analyzed in a reflexive thematic analysis. Participants were recontacted four months later, and STBs experienced since baseline were recorded. Participants frequently experienced NHEs; 169 (93%) reported at least one. Further, experiencing more NHEs was significantly associated with more frequent SI concurrently (𝜌=.61, p<.01) and prospectively (𝜌=.56, p<.01), but not when depression was included as a covariate. Community connectedness was associated with SI at baseline, even when controlling for social support and NHEs (p=.007), but not when controlling for depression. Contrary hypotheses, social support and community connectedness generally did not moderate the relationship between NHEs and SI. In qualitative analyses, we identified five themes that added context regarding participants’ adverse experiences in healthcare settings. Our results highlight contributors to suicide risk among TGNB people. Systematically improving healthcare experiences (access; care received) for these groups may ultimately contribute to suicide prevention efforts.

Published: June 2024

Melt inclusions are small parcels of magma trapped in crystals, which hold key information about pre-eruptive magmatic conditions including volatile content and melt chemistry. We focus here on melt inclusions for a nuanced view of the magmatic pre-eruptive state of Colli Albani, a mafic-alkaline ignimbrite forming system in central Italy. Recent years have seen an increased amount of research surrounding the feasibility of using melt inclusions as tracers of pre-eruptive magma volatile content including, namely the concern about measuring trapped CO2 present in vapour bubbles. Here we present synchrotron 3D tomographic scans of over 2000 melt inclusions from 35 pyroxene and leucite crystals from Colli Albani. We show that incorporating 3D information into melt inclusion geometry calculations allows for the development of a novel classification scheme, which we then use to draw inferences about the pre-eruptive evolution of the plumbing system of Colli Albani. We define six types of melt inclusions based on shape, crystallinity, and the characteristics of their vapour bubble. We also identify a strong variability in melt inclusion type proportions with stratigraphy, which ultimately is a reflection of variation in reservoir residence times, magma ascent rates, and tephra quench rates. Additionally, a large number of melt inclusions have large volume bubbles, suggesting the magma reservoir was bubble bearing at the time of melt inclusion trapping. We suggest this is essential to prepare the eruption of large volumes of the low viscosity magma at Colli Albani.

Published: June 2024

Objective: The United States has seen a significant increase in unaccompanied migrant children (UC) from Central America, who often experience a myriad of traumas throughout their migration journey. Although evidence-based, trauma-informed assessments and treatments exist, little is known about how community clinicians use and adapt these interventions to address the unique needs of UC. To enhance our understanding of mental health services for this vulnerable population, it is critical to characterize clinician experiences with intervention adaptation and delivery. Method: This qualitative study employs a socioecological model and descriptive phenomenology to thematically characterize the care needs of UC in the U.S. based on semi-structured interviews with 10 mental health clinicians. Results: Findings revealed several multi-level factors that warrant consideration in the assessment and treatment of UC across the individual, inter-personal, community, and societal spheres of a trauma-informed socioecological model. Results were grouped into seven themes that interact to affect assessment and treatment delivery: 1. Resilience (Individual-level); 2. Language (Individual-level); 3. Youth Needs and Values (Individual-level); 4. Clinician-Client Relationship (Interpersonal-level); 5. Caregiver Relationships (Interpersonal-level); 6. Acculturation to the United States (Community-level); and 7. Laws and Regulations (Society-level). Conclusions: Overall, findings highlight how all levels of nested ecological theory must be considered in the delivery of mental health services for UC.
Severe Ostracism: A Common, but not Frequent, Experience
Authors: Hales Andrew , Wood Natasha
Published: June 2024

Being ostracized is a painful experience. Even subtle and minor ostracism experiences threaten fundamental human needs. However, not all ostracism is the same. Some experiences are subtle and minor, like being accidentally overlooked by a stranger walking by or being ignored as a friend uses their phone; while others are more serious, like family members shunning loved ones or entire communities banishing an individual from full membership. We present a framework and instrument for identifying instances of severe (versus mundane) ostracism. Responses from a large U. S. nationally representative survey (N = 1,124) indicate that severe ostracism is common (78% having experienced it in their lifetime), but not necessarily frequent as more people indicate that they have experienced mundane ostracism. Severe ostracism is also associated with notable decrements in basic needs satisfaction, especially when experienced recently. Severe ostracism appears to be common and useful to conceptually distinguish from less-severe forms.
Better to Remember Alone than Together: A Context-Based Model of Collaborative Inhibition during Memory Search
Authors: Angne Hemali , Cornell Charlotte , Zhang Qiong
Published: June 2024

Contrary to common intuition, a group of people recalling information together remember less than the same number of individuals recalling alone (i.e., the collaborative inhibition effect). To understand this effect in a free recall task, we build a computational model of collaborative recall in groups, extended from the Context Maintenance and Retrieval (CMR) model which captures how individuals recall information alone. We propose that in collaborative recall, one not only uses their previous recall as an internal retrieval cue, but one also listens to someone else's recall and uses it as an external retrieval cue. Attending to this cue updates the listener's context to be more similar to the context of someone else's recall. Over an existing dataset of individual and collaborative recall in small and large groups, we show that our model successfully captures the difference in memory performance between individual recall and collaborative recall across different group sizes from 2 to 16, as well as additional recall patterns such as recency effects and semantic clustering effects. Our model further shows that the contexts of collaborating individuals converge more than the contexts of individuals who recall alone, and this convergence is negatively associated with recall performance. We discuss the contributions of our modeling results in relation to previous accounts of the collaborative inhibition effect.
Vaccine Misinformation and Social Determinants of Vaccine Intentions in a Pandemic
Authors: Shanker Ankit
Published: June 2024

Objective: This study explores the indirect effects of misinformation on vaccine intentions via social norm perceptions.Methods: A causal mediation analysis with 332 participants was conducted, examining the direct and indirect effects of misinformation on vaccine intentions through social norms. Participants reported beliefs and intentions in response to a hypothetical pandemic scenario involving a fictitious virus, COVID-66.Results: Misinformation significantly reduces vaccine intentions. Post misinformation exposure changes in first-order normative beliefs mediated about 40% of the total effect on vaccine intentions. When pre-post changes in both first and second-order beliefs were considered, the mediation effect increased to 43.93%. Specifically, changes in beliefs about neighbours mediated 56.91% of the misinformation effect, followed by friends (56.24%), work colleagues (52.66%), and city population (50.62%).Conclusion: Social norm perceptions play a critical role in the impact of misinformation on vaccine intentions. Public health interventions should combine misinformation correction with efforts to shape positive social norms, particularly within close social groups, to enhance vaccine uptake.Keywords:

Authors: Chowi Sanju Subedi , Thapa Nirupa , Sharma Sharada , Chapagain Bipin
Published: June 2024

Introduction: Adolescents are highly vulnerable to different types of emotional and behavioral problems and often have serious negative consequences for their academic achievement and potential social life. The main objective of the study was to assess the emotional and behavioral problems among school-going adolescents in Pokhara.
Methods: A descriptive cross-sectional study was conducted using the standard tool, Strengths and Difficulties Questionnaire (SDQ) among 305 adolescents studying in grades 8-10 of three randomly selected government secondary schools of Pokhara Metropolitan City through probability multi-stage sampling. Data was entered into the software EPI-DATA 3.1 and SPSS- 16 version was used for data analysis. Descriptive and inferential statistics (Chi-square test) were used to identify level of emotional and behavioral problems and to measure the association between emotional and behavioral problems, respectively.
Results: Results showed that 5.2 percent of adolescents got abnormal scores on Emotional and Behavioral Problems. On classification, 8.5 percent of adolescents have emotional problems. Likewise, 7.2 percent and 1.3 percent adolescents got abnormal scores on conduct problems and hyperactivity, respectively, which are considered as behavioral problems. Factors like sex, type of family, number of close friends, and hours spent with friends were found to be significantly associated with emotional and behavioral problems among adolescents.
Conclusions: Hence, it is concluded that emotional problems and peer relationship problems are common among girls, and hyperactivity and conduct problems are common among boys. An intervention strategy such as school-based mental health services might be beneficial to understand adolescents’ problems and providing appropriate counseling.

Published: June 2024

Introduction: Stroke is the common cause of death and leading cause of adult disability. Functional abilities may improve by comprehensive rehabilitation program in acute phase of stroke. Reintegrate the survivor in the community is very important. But effectiveness of rehabilitation program and intervention are limited. The aim of the study is to appraise the state of art to improve the effectiveness and efficiency of stroke rehabilitation among stroke survivor.
Methods: A descriptive literature review was conducted from online databases using key words stroke rehabilitation, stroke survivors, post stroke, physical rehabilitation. A total 25 were searched using search databases of PubMed, CHINAL, Google Scholar, ProQuest, and NepJOL by December, 2022.
Results: After extensive literature search, existing evidence based practices related to effective ness and efficient rehabilitation for stroke survivors are classified into five main types. They are 1) technology based post-stroke rehabilitation, 2) physical exercise based rehabilitation, 3) cognitive rehabilitation, 4) educational rehabilitation, and 5) complementary and alternative therapies specially yoga.
Conclusions: Technology based therapies are the first choice for physical rehabilitation among stroke patients. But those therapies are more not feasible everywhere because of more expensive and need special equipment and well managed setting for practice. In contrast, yoga has been used extensively with given more priorities in physical as well as holistic health outcomes. Yoga is more cost effective, safe, can practice in any setting.

Для технологічного процесу прокатки металу в листопрокатних цехах актуальним є завдання підвищення якості нагріву заготовок у методичних печах. Контроль та оптимальне управління режимами нагріву металу дозволить істотно знизити втрати металу з окалиною та покращити процес прокатки.
Порівняльний аналіз існуючих систем контролю технологічних процесів, побудованих з використанням «традиційних» математичних моделей та методів штучного інтелекту, виявив переваги останніх, такі як наочність реалізації принципів послідовного прийняття рішень, висока достовірність розпізнавання, наявність алгоритмів навчання, що не вимагають зберігання великих обсягів інформації, відсутність необхідності перенавчення системи.
Запропоновано застосування штучних нейронних мереж для побудови системи контролю та діагностики процесу нагріву слябів у технологічних зонах методичної печі. У завдання створюваної системи входить стеження за вхідними параметрами, що характеризують перебіг технологічного процесу нагріву слябів та видача рекомендацій щодо коригування цього процесу.
Спроектована нейронна мережа є одношаровою з прямою передачею сигналу та складається з чотирьох персептронів, кожен з яких відповідає певній технологічній зоні печі. Навчання мережі відбувається за дельта-правилом. Алгоритм навчання та роботи мережі реалізований у математичному пакеті Matlab. Нейронна мережа діагностує відхилення технологічних параметрів від нормального режиму, що може призвести до перегріву слябів та їх пошкодження, а також до перевитрат газу, та може бути налаштованою і на діагностування недогріву металу.
Застосування системи передбачається у складі інтегрованої автоматизованої системи керування товстолистовим прокатним станом. Вихідний сигнал системи може бути використаний у системі автоматичного керування процесом нагріву металу в методичній печі.

In the Southern Steppe of Ukraine, the agricultural sector attaches primary importance to grain production. Wheat stands out as the dominant crop among the diverse cultivated plants of this region. In place of spring wheat, a significant part of crops is occupied by winter barley. The combination of winter and spring contributes to the growth of both crops, ensuring a diverse and high yield [1]. For the intensification of grain production and the full use of the biological potential of spring barley varieties, the development of resource-saving growing technologies is relevant in modern times. The steppe zone of Ukraine presents difficult conditions for agricultural crops, as rising temperatures and drought limit their productivity by depriving them of moisture. Among the decisive factors for successful plant growth, moisture plays a significant role, but when it comes to the technology of growing winter barley, one of the key elements that cannot be forgotten is nutrition, as it plays a significant role in the development of all agricultural crops

Published: June 2024

У статті розкрито зміст феномену «особистісного здоров’я», під яким розуміється зріла особистість, яка характеризується комфортним станом відносин з собою та світом, сприятливим для її успішного самовизначення, самореалізації, саморозвитку та самозбереження. Повноцінне особистісне здоров’я засвідчується балансом індивідуальних потреб та соціальної спрямованості дошкільника та дозволяє дитині стати самодостатньою, набути внутрішнього погляду та усвідомити життєві орієнтири. Схарактеризовано концепцію розвитку психологічно здорової особистості у дошкільному дитинстві. Розкрито важливий аспект особистісної зрілості дитини – розвиток ціннісного ставлення до самої себе. Ціннісно ставитися до себе, означає усвідомлювати свою значущість для рідних, поважати себе, відстоювати власну гідність. Виділено особливості самовизначення у дошкільному дитинстві: уміння дитини самовизначатися, приймати власні рішення, здійснювати самостійні вибори великою мірою визначаються її здатністю орієнтуватися, аналізувати, порівнювати, узагальнювати. Розроблено критерії та показники, за якими визначено рівні сформованості психологічно здорової особистості дошкільника. Критеріями оцінки виступив комплекс з чотирьох основних життєво необхідних зростаючій особистості умінь: добре орієнтуватися та доцільно самовизначатися; здатності повноцінно реалізовувати свій потенціал; схильності до саморозвитку, праці над собою, самовдосконалення та вироблення базових якостей особистості; турбота про самозбереження, захисну поведінку, відстоювання особистої території. Описано авторську типологію особистісного здоров’я дошкільника, до складу якої увійшли чотири основні типи: конструктивно-гармонійний, конструктивно-фрагментарний, деструктивно-агресивний, конформно-інфантильний. Визначено основні психолого-педагогічні умови оптимізації освітнього процесу ЗДО, спрямованого на забезпечення особистісного здоров’я дошкільників, до яких віднесено: поглиблення та розширення уявлень дітей про основні життєві тенденції (самовизначення, самореалізація, саморозвиток, самозахист); сприяння розвитку довіри до себе, до своїх можливостей; підтримка балансу проявів внутрішнього і зовнішнього життя дитини; з допомогою педагогічної оцінки піднести особистісне здоров’я до найвищих людських цінностей.
