Published: January 2022

Ketersediaan LKS matematika untuk siswa SMA yang beredar saat ini sebagian besar hanya berisi ringkasan materi, contoh soal dan kemudian soal sehingga siswa cenderung menghafal dan tidak membangun suatu konsep. Hal ini menyebabkan kurangnya tingkat pemahaman siswa. Oleh karena itu, perlu dikembangkan LKS yang dapat memperdalam pemahaman siswa yaitu dengan mengembangakan LKS yang berkarakteristik REACT. Model pengembangan yang digunakan dalam penelitian ini adalah model pengembangan Plomp yang terdiri dari empat tahap yaitu 1) Tahap Investigasi Awal, 2) Tahap Perancangan, 3) Tahap Realisasi, 4) Tahap Tes, evaluasi, dan Revisi. Berdasarkan hasil uji kevalidan, uji kepraktisan, dan uji keefektifan yang diuraikan pada Bab IV, secara keseluruhan produk LKS yang dikembangkan dinyatakan valid dengan persentase 85,16 persen, praktis dengan persentase 85,6 persen, dan efektif karena semua subjek uji coba mendapatkan nilai lebih dari 75 saat mengerjakan soal evaluasi. Jadi dapat disimpulkan bahwa LKS yang dikembangkan telah memenuhi kriteria baik dan layak digunakan sebagai alternatif bahan ajar matematika pokok bahasan Barisan dan Deret.

Authors: Franciska Hidayat Beliarova , Diantoro Markus , Fuad Abdulloh
Published: January 2022

Orientasi medan magnet luar yang dikenakan pada pita superkonduktor dapat mempengaruhi nilai rapat arus kritis. Penelitian ini bertujuan untuk mengetahui pengaruh orientasi medan magnet terhadap rapat arus kritis pita superkonduktor BSCCO-2223/Ag, BSCCO-2223/Ag didoping SrCO3 10 persen, dan BSCCO-2223/Ag didoping BaZrO3 10 persen. Penelitian ini diharapkan dapat digunakan sebagai referensi untuk rujukan tentang pengaruh orientasi medan magnet terhadap rapat arus kritis pita superkonduktor. Data yang digunakan dalam penelitian ini diperoleh dari pengukuran nilai arus I dan tegangan V menggunakan 4-probe pada medan magnet luar H = 0,1 T dan 0,5 T, suhu 77 K serta sudut orientasi medan magnet dari 0 derajat -90 derajat yang dilakukan di labolatorium IEE-SAV Brastislava Slovakia. Penelitian ini menganalisis data pengaruh orientasi medan magnet terhadap rapat arus kritis pita superkonduktor BSCCO-2223/Ag, BSCCO-2223/Ag didoping SrCO3 10 persen, dan BSCCO-2223/Ag didoping BaZrO3 10 persen. Hasil penelitian menunjukkan bahwa nilai rapat arus kritis Jc menigkat secara eksponensial seiring pemberian sudut orientasi medan magnet dari 0 derajat sampai 90 derajat. Hal ini dikarenakan pemberian sudut orientasi dari 0 derajat sampai 90 derajat mengakibatkan nilai medan magnet B semakin berkurang, maka gaya pinning vorteks semakin besar sehingga rapat arus kritis Jc juga semakin besar karena nilai medan magnet B berbanding terbalik dengan rapat arus kritis Jc. Sesuai dengan persamaan gaya pinning F=J c×B.

Authors: Nahar Mst. Nasrin , Islam Md. Tarikul , Kar Diganta Broto
Published: January 2022

Nonlinear partial differential equations are mostly renowned for depicting the underlying behavior of nonlinear phenomena relating to the nature of the real world. In this paper, we discuss analytic solutions of fractional-order nonlinear Schrodinger types equations such as the space-time fractional nonlinear Schrodinger equation and the (2+1)-dimensional time-fractional Schrodinger equation. The considered equations are converted into ordinary differential equations with the help of wave variable transformation and then the recently established rational ( )-expansion method is employed to construct the exact solutions. The obtained solutions have appeared in the forms of a trigonometric function, hyperbolic function, and rational function which are compared with those of literature and claimed to be different. The graphical representations of the solutions are finally brought out for their physical appearances. The applied method is seemed to be efficient, concise, and productive which might be used for further research.

Simulation in pediatric nursing education: Are there enough evidence for future practice?
Authors: John Bindu , Marath Usha
Published: January 2022

Research on simulation is still a developing field in nursing and simulation-based learning is gaining momentum with its application over the past two decades in nursing education. Simulation is utilized as a method of training, by helping the learners for competent practice and to improve patient safety, but not much evidence is available for its application in pediatric nursing education.

This study aimed to (1) describe the application of simulation in teaching pediatric nursing education and (2) explore the evidence for its application in developing clinical competencies and skills in nursing students taking pediatric courses.

A literature search was conducted in Google Scholar, PubMed, Medline, Science Direct & ProQuest for the relevant articles available on the internet. Descriptive, experimental, and systematic reviews concerning simulation in pediatric nursing were included.

Mixed results were cited in studies about imparting the knowledge concerning the applicability of simulation in pediatric nursing courses. Available evidence shows that simulation can improve the competency of students in clinical practice and in improving patient care outcomes and communication skills. There is a paucity of studies about the applicability of simulation in pediatric nursing education.

Simulation is found to be a useful strategy in providing a near-to-real experience for the students to practice high-risk, rare procedural skills in pediatric nursing education. However, further, evidence is required to replace clinical practice experience with simulation, for sustained improvement in patient care outcomes, and in critical thinking and knowledge retention in nursing students.

PREVENTION OF TAKING UP THE HIGHEST POSITION IN THE CRIMINAL HIERARCHY: CULTURAL ASPECT
Authors:   Togliatti State University, Kondratyuk S. V.
Published: January 2022

The paper analyzes the features of the criminal subculture that contribute to strengthening the criminal hierarchy and occupying the highest position in it. Regulatory and attributive features of the criminal subculture are highlighted. The corresponding cultural measures aimed at prevention of taking up the highest position in the criminal hierarchy are reduced to overcoming totalitarianism and extremism, the cult of criminal leaders’ personality, restriction on the use of cult tattoos, jargon, and other attributes of the criminal subculture. It is specified that when identifying a person who holds the highest position in the criminal hierarchy, special knowledge is essential not only regarding the mental sphere of the criminal but also about the criminal “world”, which in its whole forms a certain criminal subculture. It is proved that the attributive elements of the criminal subculture perform a number of functions in the criminal world, such as communication, conspiracy identification, and stratification as they allow to establish affiliation of a particular individual to a particular criminal caste. The paper specifies cultural determinants of taking up the highest position in the criminal hierarchy, and on their basis describes criminological approaches to prevent this type of crime. It is emphasized that the subject of cultural expertise in establishing the fact that a person holds a higher position in the criminal hierarchy is the specific status of this individual, the features of its acquisition, and the presence of distinctive attribute elements. The main task of the expert is to determine the conformity of the process of taking up a specific criminal status by a person to existing norms and traditions of the criminal community.

Today, the information-based approach actively penetrates the investigative and litigation practice. However, its cybernation involves organizational difficulties, which make investigations in this field actual. The paper deals with the issues of forensic accounting application as an information source in criminal procedure. Forensic accounting is considered an independent doctrine in criminalistics. The paper presents the comprehension of a forensic accounting object. It is recommended to use the matrix representation of objects and their features. The study shows the prospects of combining forensic registration and accounting. The author considered new objects of forensic accounting, including digital footprints, and identified a tendency towards the formation of an integrated information-retrieval space for the tasks of investigative and litigation practice. The author analyzed the negative factors affecting forensic accounting objects and information transmission channels. To identify these factors, the author proposes to conduct a comprehensive expert study of registered objects to establish the fact of their falsification, modification, or distortion. To ensure information security, it is suggested to apply the duplication principle against the information contained in the object characteristics and physical data carriers. The positive effect is achieved by using numerous information signals transmitted in various forms through independent channels. The information systems based on the study of vein patterns, retinoscopy, the study of signs of the flexor lines pattern, odontometry, and on the signs of the auricle, as well as based on physiological, behavioral, and other dynamic characteristics of a person are recognized as promising. The author concludes on the fuzzy nature of the representation of forensic accounting objects, and to eliminate this negative factor, proposes using semantic search algorithms.

One of the main ways of achieving mercenary purposes in thefts committed using the information and telecommunication technologies is the application of social engineering techniques implemented through the psychological influence methods and aimed at controlling the consciousness and behavior of people. Late identification of such thefts and the shortcomings when collecting primary material during the preliminary investigation indicate the necessity to study the features of their mechanism of marking formation. The paper deals with the forensic characteristics of the material, ideal, and electronic-digital traces peculiar for this type of crime. Material traces are represented as traces-objects (technical devices adapted for the social engineering methods implementation, SIM cards, bank cards, documents), and traces-displays (biological traces allowing to identify that the theft of funds is committed by a specific person using a particular technical device). As the ideal traces, the authors consider the mental image of a crime committed in the mind of a person presented in the evidence of a victim, suspect (accused), witness, expert, specialist, and other persons, resulting from the illegal remote actions of a suspect (an accused) to have psychological influence (the use of social engineering methods) on a victim using the information and telecommunication technologies. The paper defines digital traces, considers their specific examples depending on the use of the Internet and (or) computer, mobile devices, and the social engineering methods by intruders. The authors formulate the typical trace pattern of analyzed thefts, the knowledge of which allows obtaining the forensically important information on the way and nature of a crime, persons involved in it, and determining the tactics of follow-up law enforcement intelligence and investigative actions.

Positive body image is a construct that has actively been formed in the last two decades. Its appearance in the psychological discourse was a kind of response to the spreading of the practice of studying the body image from the point of view of pathology in the context of clinical studies of the second half of the XX century. Currently, the world has accumulated some experience in studying a positive body image, which is especially relevant in the pandemic era. The paper analyzes contemporary foreign publications considering a positive body image published in English-language journals on developmental, clinical, and social psychology from 2001 to 2021. The research allows monitoring the transformation of the studied construct in the context of humanistic and positive psychology that considers the body image both through the concept of appearance and through such definition as body functionality. The emphasis on the functionality within the analysis of the embodiment problematics allowed shifting the focus of the psychologists’ attention from the strategies of object attitude to a body to the strategies of taking care of a body as a value. The authors highlight the key areas of studying a positive body image at the current stage of development of science: the characteristics of a structure and components of the phenomenon under the study; the search for the sociocultural, family, and individual-psychological factors influencing the formation of positive body image; the assessment of the efficiency of prevention and correction programs aimed at the promotion of healthy body image; the analysis of positive body image as a recourse of a personality in the pandemic epoch.

Among the many forms of interaction between the economic process participants, which cause the necessity to improve constantly management process, the partnership relations covering a wide range of issues take a specific place: from the formation of motives, goals, and cooperation mechanism to determining its results and consequences. This issue has particular importance in the regional business environment since the strategic partnership at the regional level allows significantly expanding the spatial boundaries to synchronize the interests of enterprises and entrepreneurial structures functioning in different spheres and industries, and using regulatory mechanisms of their economic behavior and the ways of interaction of the state, business, and society. The paper considers different approaches to strategic partnership management. The study proves that the dualism of the concept of strategic partnership management in the regional business environment is a complementarity of conceptual approaches to strategic partnership management, which implies their combination and mutual complement. The authors built the complementarity scheme of conceptual approaches to the strategic partnership management in the regional business space; determined the main goal and key tasks of the strategic partnership management of entities operating in the regional business environment. The study identified that the use of a strategic approach to strategic partnership management is determined by the architectonics of this concept and the necessity of effective adaptation of the partnership interaction to the changes in the external environment. It, in turn, ensures the achievement of strategic goals and the creation of sustainable competitive advantages of partners in the long-term outlook. The authors propose a scientific and methodological approach to the formation of the competence-constitutive basis for the strategic partnership management in the regional business environment, which is a triad of the logically ordered definitions of a two-level pyramid of the existing competencies of potential partners, a partner-initiator, and the motives, goals, and interests of potential partners.

To increase labor efficiency, the level of quality of work-life (QWL) of the working population is of particular importance. The limited number of studies dealing with the research of the quality of work at the regional level has confirmed the research interest. The paper presents the results of the assessment of QWL of the working population of the Vologda Region obtained using the subjective approach. The authors studied special aspects of regional differentiation of the assessment of the labor activity quality by the population. The paper draws attention to the fact that in the Vologda Region, the assessments of the working population concerning satisfaction with various aspects of labor activity have a lower level compared to similar data in the subjects of the Northwestern Federal District and Russia. The paper shows the results of the QWL assessment of the Vologda Region population in the context of various socio-demographic groups based on the index system of indicators. The study identified that more than half of the economically active population of the region is satisfied with the quality of labor activity. The authors found that the degree of satisfaction with the QWL varies for different socio-demographic groups of the population. The highest level of assessments is demonstrated by the groups with the increased level of wages, as well as those with higher education, officially registered marriage, and carrying out labor activities following their inclinations, abilities, and avocation. The authors conclude that the quality of labor potential and the level of implementation in labor activity of the qualitative characteristics of the Vologda Region residents significantly correlate with the QWL satisfaction. The paper presents a list of measures promoting the improvement of QWL satisfaction.
