Improving Outreach Activities — Mentoring Youth in a Structured Skills-Based Development Program Increases Personal Growth of College Students Studying Abroad
Authors: Zhao Lily , Keil Katherine , Flittner Brittany , Farquhar Samantha , Allison Edward
Published: March 2023

As study abroad education becomes increasingly common, so does the need to understand how different outreach opportunities alter the study abroad experience. To determine how outreach program design links to perceptions of personal growth, we surveyed 72 college students who participated in different youth outreach activities while studying abroad. Being a mentor in a sequenced, active, focused, and explicit (SAFE) youth outreach program increased the probability of perceived personal growth in college students by 27% relative to unstructured outreach activities in the same location. Thus, we suggest the SAFE framework be considered when designing youth outreach activities. Additionally, 44% of respondents considered outreach options as a factor when selecting a study abroad program. Combined, these findings provide an incentive for study abroad organizations to invest in structured youth outreach opportunities for their clientele—in what may be a triple-win opportunity for study abroad organizations, their students, and youth in host country locations.
Abstract in Spanish
A medida que los programas para estudiar en el extranjero se vuelven más comunes, también lo hace la necesidad de entender cómo los diferentes programas de voluntariado impactan la experiencia de estudiar en el extranjero. Para determinar cómo el diseño de programas de intercambio se relaciona con la percepción de crecimiento personal en la población estudiantil encuestamos a 72 estudiantes universitarios que participaron en diferentes actividades de voluntariado para jóvenes mientras estudiaban en el extranjero. Ser mentor en un programa de alcance juvenil secuenciado, activo, enfocado y explícito (SAFE) aumentó la probabilidad de crecimiento personal percibido en estudiantes universitarios en un 27 % en relación con las actividades de alcance no estructurado en el mismo lugar. Con estos hallazgos, sugerimos que se considere el marco SAFE al diseñar actividades de intercambio para jóvenes. Asimismo, el 44% de los encuestados consideró las opciones de voluntariado como un factor al seleccionar un programa de estudios en el extranjero. Combinados, estos hallazgos brindan un incentivo para que las organizaciones de estudios en el extranjero inviertan en oportunidades estructuradas de alcance juvenil para su clientela, en lo que puede ser una oportunidad triplemente beneficiosa para las organizaciones de estudios en el extranjero, sus estudiantes y los jóvenes en las ubicaciones del país anfitrión.
Near-Term Effects of Short-Term Study Abroad: A Longitudinal Examination of Learner Perceptions
Authors: Müller Mareike
Published: March 2023

A relatively small body of research has been conducted on the near- and long-term effects of study abroad (SA) to date. This existing research suggests that SA effects on language skills tend to be volatile, while the impact on various aspects of learners’ personal, academic, and professional development may be longer-lasting. Yet, learner perspectives on the dynamics and durability of such effects, in particular in the context of short-term SA programs, remain largely unexplored. This study hence investigates the near-term impact of short-term SA programs as experienced by students within the first months and years following their sojourns. A qualitative case-study design is employed to examine the accounts of four American students of German, who studied abroad in Austria for four weeks and were interviewed repeatedly over a period of up to 40 months after their sojourns. The results suggest that, from the students’ perspective, many effects deteriorate in the near term, although the overall sojourn experience still appears influential.
Abstract in German
Nur wenige Forschungsvorhaben haben sich bislang den mittel- bis langfristigen Auswirkungen studentischer Auslandsaufenthalte gewidmet; die bisherige Datenlage deutet jedoch darauf hin, dass die Auswirkungen auf sprachliche Kompetenzen eher unbeständig sind, wohingegen die persönliche, studiums- und berufsbezogene Entwicklung der Lernenden länger von einem Auslandsaufenthalt beeinflusst wird. Die Dynamik und Beständigkeit derartiger Auswirkungen wurden jedoch kaum mit Blick auf kurze Auslandsaufenthalte (≤ acht Wochen) sowie aus der Perspektive der Studierenden erforscht, was die vorliegende Studie insbesondere hinsichtlich mittelfristiger Effekte fokussiert. Mittels eines qualitativen Fallstudiendesigns werden die Interviewdaten vier amerikanischer Deutschlernender untersucht, die sich vier Wochen in Österreich aufhielten und in einem Zeitraum von bis zu 40 Monaten nach ihrem Aufenthalt wiederholt befragt wurden. Die Ergebnisse zeigen, dass viele Auswirkungen eines solchen Aufenthalts aus studentischer Perspektive mittelfristig verblassen, auch wenn der Auslandsaufenthalt im Gesamten weiterhin als einflussreiche Erfahrung wahrgenommen wird.

Authors: Merklen Emily , Wolfe Kara , Newell Amanda
Published: March 2023

As the U.S. population becomes more diverse, employers are seeking individuals who can work with people of various cultures. This study sought to answer if international travel, and more specifically study abroad, impacted dietetic students’ cultural intelligence. Over 400 responses from dietetic undergraduate and graduate students were analyzed with hierarchical regression and results showed that traveling abroad, as well as length of study abroad were significantly related to the cultural intelligence of students. The lack of diversity in the profession of dietetics, coupled with our growing global world, demonstrates the need for educators and administrators to ensure dietetic professionals are positioned to meet the diverse needs of their patients and clients.
Abstract in Spanish
A medida que la población de los Estados Unidos se vuelve más diversa, los empleadores buscan personas que puedan trabajar con personas de diversas culturas. Este estudio buscó responder si los viajes internacionales, y más específicamente los estudios en el extranjero, impactaron en la inteligencia cultural de los estudiantes de dietética. Se analizaron más de 400 respuestas de estudiantes de pregrado y posgrado en dietética con regresión jerárquica y los resultados mostraron que viajar al extranjero, así como la duración de los estudios en el extranjero, estaban significativamente relacionados con la inteligencia cultural de los estudiantes. La falta de diversidad en la profesión de la dietética, junto con nuestro creciente mundo global, demuestra la necesidad de que los educadores y administradores garanticen que los profesionales de la dietética estén posicionados para satisfacer las diversas necesidades de sus pacientes y clientes.

Authors: Shen Ya-hui , Wang Ya-jun , Yang Fang
Published: March 2023

With the gradual depletion of traditional fossil energy and the increasing demand for electricity, finding new energy sources has become the only way for sustainable development. Microgrid is becoming an important auxiliary power for some developed and developing countries to solve the supply problem of energy system, which can not only effectively improve the overall utilization rate of renewable energy, but also improve the power supply reliability of the main grid. In this paper, the hardware circuit and software control of microgrid simulation system based on STM32 are studied and designed. The main circuit design of microgrid simulation system is based on STM32 single chip microcomputer as the main control core, and the pulse modulation signal SPWM is output through the software program of STM32F103CBT6 single chip microcomputer. The MOS driving circuit provides driving voltage and control signal to drive the inverter bridge to invert DC into AC. The inverter bridge is modulated by SPWM control technology, and the high-frequency signal in AC is filtered by low-pass filtering circuit, and finally the stable AC with a fixed frequency of 50 Hz is the output. By calculating the device parameters of the main control circuit and the full-bridge inverter circuit in the hardware unit circuit, and making appropriate selection of components, the specific model is determined, and finally the circuit design of the whole circuit is completed. The hardware circuit is designed rationally by Altium designer, and the software circuit is programmed by Keil. The influence of SPWM signal output by the circuit on the resistance load and its output waveform is analyzed comprehensively, and the influence of working frequency on the output waveform of the circuit is studied.

Estimation of pressure effect on the crystallization process control based on a generalized theoretical model of a crystallizing metal
Authors:   Denisov M.S. Petreshin D.I.
Published: March 2023

It is installed, that on aspects such as automation and control, liquid and/or crystallizing metal is a complex dynamic object, whose properties correspond to rheological body properties. Conclusions were made that the casting structure formation during crystallization proceeds under the influence of two main factors — heat removal to the mold wall and metallostatic pressure. Theoretical studies shown that the deformation of cast metal is carried out in order to correct defects but does not give this metal greater strength. It is established, by using the results of computational and theoretical studies that for efficient control of the crystallization process, it is necessary to calculate the solidification rate, and crystallization control can be reduced to control the metastable state interval.

Authors: Sablin P.A. , Shchetinin V.S. , Mokritsky B.Ya. , Yurchenko M.S.
Published: March 2023

The paper presents the results of an experimental study of the roughness of the treated surface using various methods of data analysis, such as the analysis of Fourier spectra. Also in the work, the process of mechanical processing is considered from the standpoint of mesomechanics, which makes it possible to re-evaluate the process of chip formation. The paper says that the roughness of the treated surface, as an output parameter of the cutting process, has a special effect not only on the quality of the surface layer, but also on the performance characteristics of machine parts operating in extreme conditions. Also, the paper considers the nature of the formation of micro-roughness on the surface of parts after machining, and lists the factors that affect the roughness parameters. Conclusions are drawn about what determines the different frequencies of micro-roughness of the treated surface.
UNTOUCHABILITY AMONG MUSLIMS? FINDINGS OF A CASE STUDY IN PAKISTAN
Authors: Khaista Rahman  , Akram Muhammad
Published: March 2023

The notion of untouchability, i.e., certain social groups are impure and polluting, is generally associated with the Hindu religious tradition. However, a few studies maintain that upper-class Muslims, too, observe it in some parts of South Asia. Against this background, the present paper investigates the validity of these claims as regards the practice of untouchability among Muslims towards Christians based on data collected during a field study on Christian-Muslim social interaction in Peshawar, Pakistan. The method combined a quantitative survey and qualitative interviews.According to the study, 65.2% of Christians disagreed with the statement that Muslims consider them untouchables. Similarly, the majority (61.8%) of Christians insisted that they were never hated, while the majority (95.9%) of Muslims also rejected the claim that they hated Christians. The downside of these findings is that around one-third of Christians view that they are treated as untouchable by their Muslim compatriots. Results from the interviews also corroborated these quantifications. The paper concludes that although the Islamic teachings do not support the idea of untouchability towards human beings of any fold or affiliation, some Muslims in Pakistan still practice it towards a particular Christian ethnicity (chuhras), considering them sanitary workers. The stigma attached to this Christain community is primarily because of their occupation rather than confession. Associating any ethnic or religious group with unclean professions and then considering them untouchable is a social evil that needs to be eradicated.

One of the essential components of a wireless high-power transfer system for heavy-duty electric vehicles is the inductive coupler. The efficiency of the wireless power transfer system strongly depends on the geometric parameters of the inductive coupler, which in turn have an important effect on the electromagnetic parameters of the whole system. The transmitting (Tx) and receiving (Rx) coils of the inductive coupler proposed in this paper have a Double-D planar structure and are located on magnetic cores made of magnetic concrete (Tx) and ferrite (Rx), respectively. The study of the parameters of the inductive coupler was carried out with the help of the finite element method, using the Flux ® field calculation software package.

Currently, the study of the effect of drilling fluid slurry on the well bottom during the drilling of oil and gas wells remains one of the urgent problems in the center of attention. The main purpose of research on the dynamics of drilling fluid (or drilling mud) during the drilling process is to gather information about the effect of drilling fluid on the drilling process. As a result of this research, more detailed information about the effect of drilling mud on the well bottom will be determined, and based on that information, strategies will be drawn up for the selection and use of drilling mud to make the drilling process more effective, safe and successful. Drilling mud is a homogeneous mixture of two or more substances. system is understood. A solution is a mixture consisting of one or more soluble components and also solvents. In general, both dissolved components and solvents can be solid, liquid or gaseous. At this time, the dissolved substances are constantly distributed in the form of small particles in the solvent environment, causing the formation of a new dispersed system called a solution. At this time, dissolved substances create a dispersed phase, and solvents create a dispersed medium. The clay solutions in the drilling solution can be called the dispersed system, the dissolved clays can be called the dispersed phase, and the water, which is the solvent, can be called the dispersed medium. When used for unconventional formations, selecting a drilling fluid based on data from conventional reservoirs may be the wrong choice. During exposure to the drilling fluid, the drilling fluid has a chemical-mechanical effect on the formation rock; this interaction may be sharp or subtle, depending on the minerals that make up the rock structure and their chemical sensitivity to the fluid composition. Improper selection of drilling fluid can lead to strong rock-fluid interactions, resulting in wellbore instability. This paper presents a comprehensive experimental study investigating the effect of different drilling fluids on the mechanical properties of conventional and unconventional rock samples. Studying the dynamics of the impact of the drilling fluid solution on the bottom of the well is an important aspect of the drilling process. This study aims to better understand how the drilling fluid affects the bottom of the well and the surrounding formation. The results of this study can provide valuable information to optimize the use of drilling fluid solution, improve drilling efficiency and reduce the risk of well damage.

PROSPECTS FOR OIL AND GAS POTENTIAL OF THE MIOCENE-PLIOCENE AND MESOZOIC DEPOSITS OF THE ABSHERON ARCHIPELAGO
Authors: Sevinj Rzayeva, Shura Ganbarova Sevinj Rzayeva, Shura Ganbarova , Amir Amirov Amir Amirov
Published: March 2023

The article is devoted to the prospects of oil and gas potential of the Miocene-Pliocene and Mesozoic deposits of the Absheron archipelago.
The geological information about the Absheron archipelago dates back to the middle of the 19th century, the century of the industrial revolution.
The offshore area of the Absheron archipelago, located to the east of the Absheron peninsula, is abundant with islands, surface and underwater hidden rocks, ridges, ledges and sand banks. The largest islands of the archipelago Pirallahi and Chilov are located here. They are confined to the anticlinal folds of the same name and their formation is associated with large thrusts of the SW limbs of these structures.
The North Absheron oil and gas zone, located in the northern part of the Absheron archipelago, covers a vast territory stretching from the northwest to the southeast and is the southern end of the Scythian-Turanian Epi-Hercynian platform. An interesting feature from the point of view of the geology of the North Absheron tectonic zone is a peculiar tectonic structure, lithofacies features and oil and gas potential. Local uplifts differ from other uplifts located in the fold zone by their indeterminate location (Fig. 1).
Despite the geological and geophysical work and the drilling of numerous prospecting wells, the Miocene-Pliocene deposits of the study area have not been sufficiently studied in terms of their oil and gas potential. Drilling of numerous wells in the Miocene-Pliocene deposits did not completely open the section of these deposits. The drilling of oil and gas bearing formations with full penetration and development is mainly associated with the optimal conduct of drilling operations.
The anticlinal zone begins with structure bank Absheron. In connection with the washout on the structure bank Absheron, the upper section of the Productive series (PS) comes out on the day surface, and the lower section of the PS, with the exception of Gala suite, participates in all stratigraphic units. The Gala suite was found on the southwestern limb of the structure. Recently, hydrocarbon accumulations have been identified by prospecting and exploration work on the structures of Novkhany, Ashrafi, Garabagh. From this point of view, the correct assessment of hydrocarbon accumulations in the Miocene-Pliocene deposits in the North Absheron tectonic zone is considered the main one and complements the understanding of the oil and gas potential of the study area.

The normalized distance Laplacian matrix of a connected graph $ G $, denoted by $ D^{\mathcal{L}}(G) $, is defined by $ D^{\mathcal{L}}(G)=Tr(G)^{-1/2}D^L(G)Tr(G)^{-1/2}, $ where $ D(G) $ is the distance matrix, the $D^{L}(G)$ is the distance Laplacian matrix and $ Tr(G)$ is the diagonal matrix of vertex transmissions of $ G. $ The set of all eigenvalues of $ D^{\mathcal{L}}(G) $ including their multiplicities is the normalized distance Laplacian spectrum or $ D^{\mathcal{L}} $-spectrum of $G$. In this paper, we find the $ D^{\mathcal{L}} $-spectrum of the joined union of regular graphs in terms of the adjacency spectrum and the spectrum of an auxiliary matrix. As applications, we determine the $ D^{\mathcal{L}} $-spectrum of the graphs associated with algebraic structures. In particular, we find the $ D^{\mathcal{L}} $-spectrum of the power graphs of groups, the $ D^{\mathcal{L}} $-spectrum of the commuting graphs of non-abelian groups and the $ D^{\mathcal{L}} $-spectrum of the zero-divisor graphs of commutative rings. Several open problems are given for further work.

In this paper, we look at Diophantine triples with values in three different binary recurrence sequences. These are the Fibonacci and Pell sequences and the sequence of one more of powers of a given prime $p$. The novelty of the article is the appearance of three different sequences, as up to now the analogous problem had been investigated only for one sequence.

In this paper, we establish an affine Orlicz log-Minkowki inequality for the affine quermassintegrals by introducing new concepts of affine measures and Orlicz mixed affine measures, and using the newly established Orlicz affine Minkowski inequality for the affine quermassintegrals. The affine Orlicz log-Minkowski inequality in special case yields $L_{p}$-affine log-Minkowski inequality. The affine log-Minkowski inequality is also derived.

"We show that the choice of stepsize in Korpelevich's extragradient algorithm is sharp, while the choice of stepsize in Popov's extragradient algorithm can be relaxed. We also extend Korpelevich's extragradient algorithm and Popov's extragradient algorithm (with larger stepsize) to the infinite-dimensional Hilbert space framework, with weak convergence."
The Determinants of Online Repatronage Intention for Shariah-Compliant Hotels among Muslim Customers in Malaysia
Authors: Sulaiman Yaty , Djermani Farouk , Ismail Mohd Yusri Shahril , Arif Ariana
Published: March 2023

Research studies have investigated online repatronage intentions among international and local tourists to Malaysia on Shariah-compliant hotels (SCHs) and e-B&Bs. Malaysia’s Islamic hospitality development sector has encouraged hotel managers to observe the Islamic hotel concept according to Muslim travellers’ needs and demands. Malaysia introduced the "Muslim-Friendly Hotel Recognition, which recognises Shariah-compliant accommodation for tourists. This type of recognition could be able to empower the tourism industry. A total of 10% out of 5,520 hotels comply with Shariah requirements, indicating that the new contribution of the SCH is needed. As of now, a comprehensive standard does not exist. The purpose of this research is to provide awareness among Muslim customers in Malaysia regarding SCHs’ online repatronage intentions. The number of hotels and e-B&Bs with full Shariah compliance is still small even though the number of Shariah-friendly hotels in Malaysia has increased with 744 halal certifications issued to hotels and resorts. The hotel management should adopt Islamic teachings even with the themes, ambiances, and architecture. With this, travellers would feel comfortable to perform their religious obligations. This research aims to identify online repatronage intentions of Muslims tourists to the Shariah compliant e-lodging industry in Malaysia. Most Malaysians are unaware of the SCH's implementation. From this study, they will become aware that the SCH not only accepts Muslim customers but also openly welcomes non-Muslim customers. A self-administered online survey was conducted to attain responses. Five hundred data were cleaned from any missing case and outliers, and 395 data were used for the next analysis. The sampling technique involved data collection both from local and international tourists who intended to stay at their preferred SCHs. Analysis of the measurement model was conducted with the structural model using the bootstrapping method via SmartPLS version 3.2.9. It was found that Hotel Image and Shariah compliance attributes were significant towards online repatronage intentions among Muslim customers of the SCH.
Digital Government and Digital Governance: Grand Concept
Authors: Grigalashvili Vephkhvia
Published: March 2023

Development of digital democracy domain substantially depends on how correctly are understood conceptual dimensions and how clearly are determined functions of digital government and digital governance, as digital government represents a fundamental shift in the way governments around the world are embracing their mission and digital governance is no longer just a technological enabler. Digital government and digital governance (as terms and concepts), known as multidimensional, multifaceted and multidisciplinary phenomenon, are often treated as synonymous and used interchangeably in the academic literature or formal documents. Therefore, it is becoming increasingly difficult to clear existing conceptual ambiguity between them. There are no universally accepted definitions of both abstractions. Such conceptual uncertainty has a negative impact on the development of digital democracy. The research objective of this article is to provide a deeper understanding of digital government and digital governance concepts through empirical studies and scatter the existing ambiguity in differences between these two concepts as this variety is not just questions of academic nuance. Based on a comparative analysis of digital government and digital governance conceptual meanings, this article offers an approach according to which digital government and digital governance represents two various but closely related and co-existing concepts. Furthermore, in the concluding section of the article, there is suggested recommendation regarding development a new grand concept in which both multidimensional conceptual visions will be combined.

CONTACT PROBLEM FOR A RECTANGULAR PLATE ON ELASTIC SEEDING IN POLAR COORDINATES
Authors:   Belarusian National Technical University, BOSAKOV S.V.
Published: March 2023

In this paper, the problem of calculating a rectangular plate on an elastic base in polar coordinates by the Zhemochkin method is considered for the first time. Such problems arise, for example, when metal columns of circular cross-section are supported on rectangular bases lying on a concrete base. When solving this problem, several types of Zhemochkin plots in polar form were used. The Saint-Venant principle was widely used to determine the displacements of the elastic base from a single force distributed over a complex-shaped Zhemochkin section. Two examples are considered: a square plate on an elastic base and a rectangular plate also on an elastic base. In the last example, along with the Zhemochkin sections, rectangular sections were used in polar coordinates. Numerical results are obtained showing the phenomenon of decreasing contact stresses in places near the corners of the plate.
