The production of a child in conflict in teacher education – research on available storylines

ABSTRACT Teacher education takes part in producing childhood. This is rarely discussed in teacher education. In this study, we are interested in what kinds of positions become normalised for children and youth in the discourses in teacher education. We utilise the concepts of narrative resources and storylines, looking into the storylines in which student teachers take themselves to be in, and in the positions that are opened for pupils in these storylines. The results show that a child in peer conflict is produced in problematic ways, as an ideal child or object of fixing. Teacher is produced as central and important.

Reproduction of experimental data for stacked caffeine dimers using various computational methods

Reliable description of stacking interaction of aromatic molecules is important for the understanding structure, stability, and functions of biopolymers. The caffeine molecule is an ideal object for this study as the stacking interactions are the preferential ones for self-associations of this hydrophobic molecule without H-bond donor groups. The analysis of anhydrous caffeine crystal structures revealed five types of caffeine stacking dimers. Geometry optimization of these dimers was performed using two molecular mechanics force fields, ab-initio method Møller Plesset of the second order (MP2), and density functional theory (DFT) with different functionals. The comparison of geometric parameters of the caffeine dimers obtained using different theoretical methods with those in crystals enables us to suggest the methods providing the most reliable stacking characteristics. These methods are: the MP2 with Basis Set Superposition Error correction (MP2/CP), Poltev force field, along with PBE0-DH, SCAN and PBE-D3 functionals of DFT. For the methods, which give the dimer interaction energy close to that obtained by MP2/CP method, the evaluated sublimation enthalpy values are shown to be close to the experimental data. Additionally, MP2/CP, Poltev FF and PBE0-DH functional showed to be the methods that describe well both the energy and geometry of the caffeine stacking dimer.

Point spread function engineering enable resolution enhanced imaging for Interferenceless coded aperture correlation holography

The point spread function (PSF) of an optical system could characterize the resolving ability of the whole optical system for point light sources. Therefore, the imaging performance of the system could be significantly improved by regulating and optimizing the PSF. In this paper, we innovatively propose a single-exposure hologram resolution enhanced cross-correlation (RECC) method for Interferenceless coded aperture holography(I-COACH) system, circumventing the necessity to obtain the point spread hologram (PSH) of an ideal point object. The RECC method firstly acquires an approximate image of a large-size point object by Lucy-Richardson (LR) algorithm in lens imaging mode, and takes it as a PSF to acquire a PSH with ideal size of the I-COACH system by LR algorithm again, and finally acquires a reconstructed image by the single-exposure hologram RECC method. In the RECC method, the approximate ideal PSHs at different axial positions of the system are acquired by offline operation, therefore, it has a high imaging temporal resolution, and the imaging transverse resolution is not affected by the size of the point objects at the time of recording the PSH, which provides a high imaging signal-to-noise ratio and stable resolution. The proposed method provides powerful technical support for further extending the application field of the I-COACH system, and provides technical reference for other incoherent imaging.

The Controversy of Siyahi Marriage: A Maqasid Shariah Perspective and Its Relevance in Indonesia

The phenomenon of Nikah Siyahi, or temporary marriage during travel, has become a controversial topic in Islamic law. This practice is often carried out by Muslim travelers to enjoy sexual relations without violating religious principles. However, scholars have diverse opinions regarding Nikah Siyahi. Some endorse it as an alternative to avoiding zina (fornication), while others reject it for undermining fundamental values of marriage, such as commitment and purity. This study aims to explore Islamic legal perspectives on Nikah Siyahi and analyze the impacts of this practice through the lens of Maqasid Shariah, which are the primary principles of Islamic law intended to protect religion, life, lineage, property, and intellect. The research employs a library research method to gather views from various literatures on Islamic law. Although it may formally meet the requirements of Islamic marriage, Nikah Siyahi fundamentally contradicts the ideal objectives of marriage in Islam. From the perspective of Maqasid Shariah, this practice can have negative repercussions on the dignity of religion, mental health, family stability, and the rights of offspring. In Indonesia, where marriage law is clearly regulated, this practice brings more harm than benefit. Therefore, the enforcement of law and community education regarding the essence of marriage in Islam must be strengthened to protect fundamental values of Shariah

Penggunaan Media Komik dalam Meningkatkan Kemampuan Menulis Karangan Narasi Siswa Sekolah Dasar

The significance of creating grade school understudies' story paper composing abilities using acquiring media, particularly comic media. Indonesian is a language that should be shown in schools, and composing is an essential piece of the language educational experience. Be that as it may, numerous understudies experience hardships recorded as a hard copy story expositions, which can influence how they might interpret the language. It is trusted that the utilization of comic media as a learning device can expand understudies' advantage in learning and assist them with defeating troubles recorded as a hard copy. The exploration was done utilizing a subjective methodology, noticing straightforwardly in the field and gathering information from logical writing. The exploration results show that the utilization of comic media in figuring out how to compose account papers can further develop understudies' composing abilities, animate their creative mind, and make learning more tomfoolery and understudy focused. The examination stages incorporate preparation, execution, perception and reflection, which mean to keep on further developing learning until it accomplishes the ideal objectives

Current Trends in Modalities of Pain Assessment: A Narrative Review.

Pain is a common complaint among a spectrum of diseases. Although an ideal objective method of pain assessment is lacking, several validated tools are available for use in clinical research and practice. The tool considerations are based upon the parameters to be assessed and factors specific to patient, disease, and availability of instruments. This review classifies and brings the key aspects of currently available pain assessment tools on a single platform to ease the selection process for researchers/practitioners. The tools utilized for pain assessment were collected from articles available in PubMed and Google Scholar databases and classified into the following domains: unidimensional, multi-dimensional, investigation-based, and computerized algorithm-based tools. Their purpose of use and limitations are reviewed. The unidimensional scales are used to describe only the characteristics of pain, like intensity (e.g. numerical rating scale), type (e.g. neuropathic pain questionnaire), or pattern. In contrast, multi-dimensional tools, like Mc Gill Questionnaire, assess not only pain as an individual symptom but also its influence on physical functioning and general well-being. However, certain components like ethnicity, age, cognitive impairment, sedation, and emotion become a limiting factor in selecting the scale. In addition to these scales, a potential role of parameters such as biopotentials/markers has also been shown in pain assessment. Last, artificial intelligence is also being applied in evaluation of pain. Pain measurement is subjective in nature as assessed through questionnaires and observational tools. Currently, multi-dimensional approaches of pain assessment are available, which can lead to precision pain management.

Zircon U-Pb geochronology, major, trace elemental, and Sr-Nd-Pb isotopic geochemistry: constraints on the age and magmatic origin of Mesozoic mafic dykes in the Guangxi Zhuang Autonomous Region, South China

ABSTRACT As a direct product of lithospheric extension, the mafic dyke group have become an ideal object for studying the formation, evolution and dynamics of both the crust and continental orogenic belts. Given the scientific significance of mafic dykes and their utility in addressing outstanding questions concerning the origin and development mafic dyke swarms Mesozoic age with-in the South China Plate, in this study, 54 representative mafic dykes within the Guangxi Zhuang Autonomous Region, South China, were examined. Research methods include laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb age-dating, whole rock geochemistry, and the Sr-Nd-Pb isotope geochemistry of the studied mafic dykes. The results indicate that these rocks formed between 139 Ma and 113 Ma and have typical doleritic and lamellar textures. They fall into the alkaline and shoshonitic series, are characterized by enrichment of light rare earth elements, some large ion lithophile elements (Rb, Ba, and Sr), Th, U, and Pb, and have depleted Nb, Ta, Hf, and Ti. Moreover, the mafic dykes studied have high initial87Sr/86Sr ratios (0.7055–0.7057), negative εNd(t) values (from −15.2 to −11.4), and relatively constant initial Pb isotopic ratios (that are Enriched Mantle-1 (EM I)-like; 206Pb/204Pb = 16.765–16.816, 207Pb/204Pb = 15.429–15.476, and208Pb/204Pb = 36.882–37.144). The above results indicate that the group of dolerites and lamprophyres studied herein were likely derived from magma generated via low-degree partial melting (1.0%–10%) of an EM1-like garnet-lherzolite mantle source. The parental magmas to these fractionated olivine-, clinopyroxene-, plagioclase, and Ti-bearing phases, with negligible crustal contamination during ascent and dyke emplacement. On the basis of existing research and evidence from this study, we propose a reasonable model for the origin of the mafic dykes: the ancient Pacific Plate subducting below the South China plate led to extension of the lithosphere, an upsurge of the asthenosphere, which triggered partial melting of the lower mantle lithosphere in the Early Cretaceous, and the formation of the parent magma to the Mesozoic mafic dykes in the Guangxi Zhuang Autonomous Region study area. The involvement of slab-derived fluids from the subduction of the ancient Pacific Plate was responsible for metasomatism of the mantle source to these mafic magmas.

Gender Characteristics of Reflection in Higher Education Students in Relation to Social Intelligence

Purpose of article: to highlight the results of an empirical research on the gender characteristics of the differential type of reflection in higher education students in relation to social intelligence. Systemic reflection, which allows simultaneous coverage of both the subject and object poles, is found at a high level in all male and almost all female participants; at an average level, it is found in a small number of female participants. Introspection, which promotes focusing on the experiences of both own and other people, is identified at a high level in three-fifths of the male participants and slightly less than one-second of the female participants; at an average level, it is found in two-fifths of the male participants and slightly more than one-second of the female participants. Quasi-reflection, which involves detachment from the real situation due to a focus on an ideal object, is found at a high level in three-fifths of the male participants and slightly more than one-second of the female participants; at an average level, it is found in two-fifths of the male participants and slightly less than one-second of the female participants. No low levels of systemic reflection, introspection, or quasi-reflection were observed. Statistically significant differences were found only in the levels of introspection between male and female participants. Statistically significant correlations between the overall social intelligence indicator and systemic reflection, introspection, and quasi-reflection have demonstrated that reflection is a psychological mechanism of the development of social intelligence in higher education students with special educational needs.

(Invited) Carbon Phase Adjustment by Multi-Configuration Ligand in Endohedral Metallofullerene Derivatives Gd@C82(morpholine)7 Under High Pressure

Metallofullerenes present an ideal research object for developing new carbon structures with improved properties under high pressure. In this presentation, high pressure investigation is realized on metallofullerene derivatives (Gd@C82(morpholine)7) by applying in situ synchrotron XRD, Raman, and IR spectroscopy, combined with high pressure density functional theory (DFT) calculations. The regulations of multi-configuration morpholine ligands avoid the direct collapse of the carbon cages commonly happened to fullerenes, making the fine structure transformation possible for the first time, including ligand configuration exchange, anisotropic shrinkage of cage, new constructed bonds, and even the encaged metal’s movement with increasing pressure. The charge-transfer principle as the beneath driving force of structural transition is found. These findings demonstrate that multi-configuration ligand maps an innovative strategy for phase transition control of metallofullerenes under high pressure, thus providing deep insight, step by step, into the phase transition mechanism of these hybrid molecular systems on molecular level.

Social Sciences: Characteristics of the Subject, Attitude to Sociology

The article discusses the situation in the methodology of social sciences. There were problems with defining the subject of these sciences and distinguishing them from sociology. While some sociologists defend the specifics of sociology, others, for example, Z. Bauman, argue that "sociology is a residual discipline, which is limited by what remains outside the field of view of other social disciplines." The author, following Bauman, separates and connects sociology with the social sciences as follows: in the social sciences, the processes and interactions of people are considered as factors and anthropological conditions of the corresponding deindividual structures and processes (economic, political, legal, institutional, etc.). Answering the question about the nature of the subject of social sciences, the author argues that social sciences study, on the one hand, associations and populations of people, on the other hand, processes and patterns of their changes, on the third hand, social actions under the influence of which these changes occur. Sociology constructs its ideal objects on the assumption that the main thing in this reality are people and their relationships. Other social disciplines consider people as one of the factors and conditions, and distinguish and study various deindividual processes and structures as the main ones. These provisions are explained within the framework of methodological discourse and illustrated by the material of cultural history.

Th eology as the science of existence and philosophy as the science of being in the fundamental ontology of M. Heidegger

The article deals with the project of understanding transcendental reality, undertaken within the framework of phenomenology. It is shown that phenomenological reduction, which leaves beyond the limits of evidence all types of objects of consciousness and all types of existence, if they do not reveal their meaning within the framework of the phenomenal givenness of themselves to experience, fundamentally does not allow us to talk about the transcendent. This circumstance reveals the limitations of phenomenology and the need to supplement it with various ontological and epistemological constructions, such as positive sciences, theology, theory of objects, ontology of ideal objects, etc. The article demonstrates a project for such an addition: the fundamental ontology of Martin Heidegger. Martin Heidegger shows that phenomenology in the format of fundamental ontology Dasein has an advantage over theology, since it is the science of being, and theology is just the science of existence, namely one of its types — historical revelation. It turns out that this project separates phenomenology and theology as the basis for any positive research, including theological, and thus does not allow us to talk about a phenomenological study of the transcendent. Thus, it is shown that phenomenological philosophy and theology are fundamentally incompatible.

Design and Implementation of Smell Agent Optimizer for Parameters Estimation of Single and Double Diode in PV System: A Comparative Analysis

One of the most important and desirable options for moving toward clean electric energy sources is solar energy. Therefore, a PV system's characteristics play a significant role in determining how effective it is across a range of temperature and radiation scenarios. One can consider the PV model's parameter estimation to be a nonlinear optimization situation. This work makes use of a novel application of the smell agent optimizer (SAO) created to forecast the undefined parameters of the PV model's single- and two-diode equivalent circuits. The goal of this effort is to create an accurate photovoltaic model that can accurately represent its performance under variable operating conditions. The square of the mean squared error between the actual measured curve and the current-voltage curve derived from the model defines the intended objective function. The suggested system is constructed and tested experimentally in a range of temperature and light conditions. Next, the MATLAB software is used to create the simulated PV model integrated with the SAO. The PV parameters are then predicted by comparing the experimental data with the convergence of the SAO based on the PV model. Based on the observed properties, the suggested approach for determining the parameters of an actual solar cell has been put into practice and contrasted with eight other optimization techniques. The outstanding efficacy of the method utilized compared with alternate methods is demonstrated by the statistical comparison of the ideal objective function resulting from the difference in the current-voltage curve produced from the optimized circuit model and the measurement.

Identification of the histone acetyltransferase gene family in the Artemisia annua genome.

As the most effective therapeutic drug for malaria, artemisinin can only be extracted from Artemisia annua L., which is sensitive to the surrounding growing habitat. Histone acetyltransferases (HATs) contain acetyl groups, which modulate mRNA transcription and thereby regulate plant environmental adaptation. Comprehensive analyses of HATs have been performed in many plants, but systematic identification of HATs in medicinal plants is lacking. In the present study, we identified 11 AaHATs and characterized these genes into four classes according to their conserved protein structures. According to the phylogenetic analysis results, potential functions of HAT genes from Arabidopsis thaliana, Oryza sativa, and A. annua were found. According to our results, AaHAT has a highly conserved evolutionary history and is rich in highly variable regions; thus, AaHAT has become a comparatively ideal object of medical plant identification and systematic study. Moreover, motifs commonly present in histone acetyltransferases in the A. annua genome may be associated with functional AaHATs. AaHATs appear to be related to gene-specific functions. AaHATs are regulated by cis-elements, and these genes may affect phytohormone responsiveness, adaptability to stress, and developmental growth. We performed expression analyses to determine the potential roles of AaHATs in response to three environmental stresses. Our results revealed a cluster of AaHATs that potentially plays a role in the response of plants to dynamic environments.

Formation of Aesthetic Taste in Students of Professional Educational Organization by Means of Decorative and Applied Art

Introduction. The current stage of development of Russian society is characterized by global socio-economic changes that have caused instability in public life, a crisis of society and its main institutions, the destruction of spiritual ideals, which has led to a decrease in the level of morality and spirituality of young people, the level of formation of aesthetic taste. Therefore, the problem of lack of aesthetic tolerance is relevant, which can lead to negative phenomena in society, indifference or an aggressive attitude towards complex aesthetic phenomena that require intellectual perception. The purpose of the study is to develop and theoretically substantiate a didactic model for the formation of students’ aesthetic taste in an educational environment through the means of arts and crafts and to experimentally test its effectiveness. Methodology. To solve the problems, the following research methods were used: theoretical: ascent from the abstract to the concrete, idealization (creation of an ideal object) as a thought experiment; empirical: observation, pedagogical experiment, study of the results of artistic and creative activities of students. Research instruments are the tools that were used to collect and analyze data. We used the following tools: survey (using the survey we found answers to a number of questions that were developed for a specific group of students); an interview that helped gather information about students’ knowledge of arts and crafts; observation – this tool was used to study human behavior in various situations We studied the level of practical skills of students in the implementation of aesthetic ideas when performing an object of decorative and applied art using the association of a picture, which reflects the national idea, historical symbols and connotations – traditions and rituals, epics in the form of traditional shapes and colors, simple symbols, decorative folklore images. Based on the results obtained, in the course of empirical research, we have developed training programs for in-depth mastery of content in the disciplines “Technology” and “Fine Arts”. The thematic curriculum includes the following sections: 1. Russian art of the 18th–20th centuries. in the works of artists (I. E. Repin, M. P. Botkin, A. G. Venetsianov, P. P. Vereshchagin, etc.). 2. History of Russian culture in epics, fables, poems and fairy tales. 3. Russian decorative art. 4. Ornament as a form of Russian philosophy. 5. Ornament in the works of Khokhloma masters. 6. Ornament of Siberian carpets. 7. Understanding of beauty in Russian painting. 8. The property of Russian literature. Results. As a result of the study, a didactic model for the formation of aesthetic taste of students in the educational environment of a college was developed. The experiment confirmed the effectiveness of the developed curriculum and the identified pedagogical conditions that contribute to the most effective formation of aesthetic taste among students of a professional educational organization through the means of decorative and applied arts. Methodological products were adapted to the conditions of the Chelyabinsk Pedagogical College No. 1. After analyzing the problems identified within the framework of the study, programs for the academic disciplines “Fine Arts and Technology” and methodological recommendations for the formation of artistic and aesthetic taste through the means of decorative and applied arts were developed and implemented into the educational process of designers. Conclusions. The developed curriculum, being part of the educational process at aesthetic faculties, contains specific proposals for improving the training of specialists. Particular attention is paid to tasks for students specializing in painting. This allows us to enrich the experience of implementing creative projects and create aesthetically pleasing products of modern design. The methodological products developed during the study can be used in the professional activities of teachers of vocational training in secondary vocational education organizations.

Genesis of Hongqiling Sn-W polymetallic deposit in Dongpo ore concentration field, southern Hunan: Evidences from U-Pb chronology and trace element geochemistry of cassiterite

Hongqiling deposit is one of the most typical hydrothermal vein type Sn-W polymetallic deposits in the Dongpo ore field, southern Hunan. It is an ideal object to study the Sn-W mineralization in the Nanling metallogenic belt and even in the whole South China Block, and to reveal the regional metallogenetic regularity. Based on the detailed investigation of the deposit geology, this paper discusses the mineralization age and processes of the Hongqiling hydrothermal vein type Sn-W polymetallic deposit by LA-MC-ICP-MS in-situ U-Pb dating and trace element geochemistry of cassiterite from the quartz vein type Sn-W ore body. Cathodoluminescence (CL) imaging shows that cassiterite in Hongqiling deposit can be divided into two generations.primary cassiterite (Cst-I) and altered cassiterite (Cst-II). The LA-MC-ICP-MS in-situ U-Pb age of the two groups of Cst-I samples are 158.9 ± 0.7 Ma and 158.4 ± 0.8 Ma, respectively, which are well consistent with the mineralization ages of most Sn-W deposits in the Nanling metallogenic belt, and are also consistent with the ages of middle to late Jurassic magmatic activity represented by the Qianlishan intrusion. This indicates that the Hongqiling deposit, like many Sn-W deposits in the Nanling metallogenic belt, is genetically related to the regional Middle to Late Jurassic granitic magmatic activities. LA-ICP-MS trace element analysis shows that trace elements such as Na and Cs are mainly distributed in fluid inclusions in cassiterite, while the major elements such as Mg, Al, and Si are mainly distributed in the mineral inclusions, and other elements such as W, U, Zr, Hf and Ti are mainly distributed in the cassiterite by isomorphic substitution. The high Fe and W contents in both primary and altered cassiterite indicate that the ore-forming fluid of Hongqiling deposit is mainly derived from granitic magma. The fluctuating variation of Fe, V, Sc, Ti, Zr, Hf, Nb and Ta in the primary cassiterite with the crystalline bands indicates that there are two large-scale pulses of magmatic hydrothermal fluid during the mineralization process, while the altered cassiterite is relatively depleted of Ti, Sc, Zr and U elements, and enriched in Pb which may represent the compositional characteristics of the late-stage fluid. In summary, the Hongqiling hydrothermal vein type Sn-W polymetallic deposit was formed by the pulsating exsolution of magmatic hydrothermal fluid of late Jurassic granitic magmatism. The trace elemental compositions of primary cassiterite are generally controlled by the compositions of ore-forming fluid and the rate of crystallization.

FORMATION OF ENVIRONMENTAL COMPETENCE OF THE FUTURE BACHELOR OF NAVIGATION: THEORETICAL ASPECT

The relevance is driven by the fact that the ecological crisis both globally and in Ukraine particularly, is characterized by a trend of increase. The war with the Russian Federation, which severely destroys the country's ecosystems, has become a challenge for domestic ecology. We now face significant losses of hundreds of species of animals and plants. This requires replenishment of organizations and institutions, including maritime and water transport, with specialists who have a thorough professional-ecological training. Meanwhile, maritime higher education institutions are still insufficiently focused on activating ecological education for students, on fostering ecologically aware seafarers with developed ecological thinking. The problem of targeted formation of ecological knowledge, skills, and consciousness among future navigation specialists is further actualized by the fact that pedagogical science has not yet substantiated detailed methodological approaches, effective principles, specific conditions, and rules for productive ecological training of future specialists in maritime and inland water transport, nor has it developed effective technologies and methodologies for systemic acquisition of professionally oriented ecological knowledge, skills, and abilities by marine education seekers. Objective: To substantiate the pedagogical system of targeted formation of ecological competence in future navigation bachelors and to develop its conceptual model. Methods: To achieve the objective, the study utilized theoretical methods (theoretical analysis of scientific works, study of the requirements of environmental legal documents to clarify the level of problem development and identify directions of scientific exploration; comparison to study scientific approaches to solving the problem; analysis and synthesis to clarify the features of ecological-professional training of navigation bachelors, substantiating the content of their ecological competence formation; modeling to develop the structural-content model of the pedagogical system) and empirical methods (pedagogical observation, discussions, surveys to identify directions, stages, forms, technologies of forming ecological competence in future navigation bachelors). Results: Based on the analysis of pedagogical theory and educational practice, the peculiarities of professional-ecological training of future navigation bachelors in higher education institutions were clarified; it was determined that ecological competence of future navigation bachelors is a complex scientific object and requires a systemic approach in its research, and the process of its targeted formation should be considered as a pedagogical system; a conceptual model of the system has been developed that combines the conceptual positions of the studied process into a single ideal construct, illustrating the sequence of "movement" from the goal to the expected result. Conclusions: The substantiated model is a theoretical construct that reflects the conceptual foundations of the systemic formation of ecological competence in future navigation bachelors; the positions embedded in this ideal object regarding the formation of this integrative property of the personality combine the possibilities of intradisciplinary and interdisciplinary directions of ecological education for students with the acquisition of experience by future seafarers in environmental protection, research, ecological-enlightenment, and other activities; the implementation of the developed pedagogical system in a higher education institution will significantly enhance the level of formation of ecological knowledge, ecological thinking, ecological consciousness, and eco-safe behavior among future navigation bachelors.

Design of a Millimeter-Wave Broadband Linearizer Based on an Extended Design Space

In this study, a broadband linearizer design method based on an extended design space is proposed to optimize the design complexity and linearization performance of conventional linearizers for broadband operation. The gain characteristics of the power amplifier (PA) and linearizer are fitted to simplify the analyses and to quickly derive the ideal objective function of the linearizer design. Then, the 1 dB compression point of a nonlinear system is redefined and used to further extend the design space of the linearizer. To verify the proposed design method, a millimeter-wave linearizer prototype based on the extended design space was designed and fabricated. The linearizer was tested with continuous-wave and 100 MHz two-tone signals from 40 GHz to 43 GHz. The measurement results of the linearized PA showed that the output 1 dB power point (OP1dB) was improved by more than 1.7 dB, the phase error was reduced by more than 15°, and the third-order intermodulation distortion (IMD3) was suppressed by 8.6 dB–13.1 dB over the working frequencies. The proposed linearizer achieved good linearization performance, low power consumption, and simple design implementation, and it was not necessary to tune the bias during broadband operation, making it applicable in complex communication scenarios.

Представления юношей и девушек о будущем, раскрытые через художественный образ взросления

<p>The results of a study aimed at studying the ideas of growing up and the future in adolescents, boys and girls, are shown. The main purpose of the study was to identify the connection between life events that are significant for young people and their ideas about growing up, which is shown through the image of growing up in a feature film. The hypothesis was based on the assumption that the significance of life events in ideas about the future of boys/girls differs depending on the ideas of growing up based on the assessment of an artistic image. In total, the sample consisted of 1394 adolescents and young people aged 14 to 23 years (M=17; SD=2). Statistically significant differences were revealed in the ideas about the future of adolescents, boys and girls, with different types of ideas about growing up, revealed through an artistic image. Respondents who differ in the type of ideas about growing up show differences in the perspective of the future in relation to events related to "other people", "ideal objects" and the time period of the "open present". It was also found that there are differences in the significance of life events related to education, professional activity and communication among young people with different types of ideas about growing up based on an artistic image. These results may be useful for understanding the differences in the motivation of young people and for developing support and orientation programs in the process of growing up.</p>

The Maslahah of State Policy in Responding to Unregistered Marriage: Inclusion of Unregistered Marriage on The Family Card

Based on Minister of Home Affairs regulations No. 108 and No. 109 of 2019, unregistered (siri) marriage couples can now record their marriage in the Family Card. This article aims to analyze the policy of issuing Family Cards for unregistered marriage couples using the Islamic jurisprudence (ushul fiqh) approach. This article is a literature study, with data sourced from the Minister of Home Affairs regulations and various related literatures. The obtained data is then analyzed using a normative-philosophical approach, specifically ushul fiqh theories such as the concepts of public interest (maslahah) and preventing harm (adz-dzari�ah). The article argues that in every policy, there will be potential benefits (maslahah) and harms (mudharat). In the policy of recording unregistered marriages, the government needs to close the means that cause harm (saddu al-dhariah) to ensure this policy is not interpreted as a form of legalizing unregistered marriages. The government also needs to open the means that lead to benefits (fathu al-dhariah) so that the goal of fulfilling children's civil rights with the basis of having a birth certificate, and the purpose of the Marriage Law, namely the validity of marriage, can be achieved through the use of unregistered marriage data for expediting the marriage legalization process (itsbat nikah) in Religious Courts. The conclusion of this article is that to achieve the ideal policy objectives, aspects of benefits and harms need to be considered. This article contributes to understanding state policies from the perspective of ushul fiqh and indicates that it remains a relevant approach.
