Published: June 2024

We are currently in a period of upheaval, as many new technologies are emerging that open up new possibilities to shape our everyday lives. Particularly, within the field of Personalized Human-Computer Interaction we observe high potential, but also challenges. In this article, we explore how an increasing amount of online services and tools not only further facilitates our lives, but also shapes our lives and how we perceive our environments. For this purpose, we adopt the metaphor of personalized ‘online layers’ and show how these layers are and will be interwoven with the lives that we live in the ‘human layer’ of the real world.
Self-powered synchronous asymmetric voltage flip and charge extraction technique for piezoelectric energy harvesting
Authors: Xiao Zekun , Dong Weijie , Xie Yongping , Zhang Jiahao , Wei Yunyang , Wang Xu
Published: June 2024

This paper presents a nonlinear interface circuit for piezoelectric vibration energy harvester (PEH) with Synchronous Asymmetric Voltage Flipping and Charge Extraction process, denoted as SAFCE. SAFCE flips the PEH voltage polarity at positive peak and completely extracting charge at negative peak through LC resonance. The harvested power is independent of load. In theory, the harvested power is 200 % of SECE and 780 % of best impedance-matched SEH due to the energy injection mechanism, which enhances the electromechanical coupling coefficient of PEH. Moreover, a self-powered SAFCE circuit without rectifier bridge is designed, which reduces power consumption and eliminates the need for external power sources. Experimental measurements are carried out to compare with SEH and SECE circuits under the condition of either constant displacement magnitude (0.5 mm) or constant external excitation acceleration (10 m/s2). The experimental results indicate that the power harvested by the SAFCE technique increased by 171 % compared with the SECE method and by 381 % compared with the best impedance-matched SEH method under the same conditions.
Experimental study on flow field and combustion characteristics of V-gutter and integrated flameholders
Authors: Li Jie , Xia Tao , Sun Bolun , Song Wenyan , He Chen
Published: June 2024

To optimize the integrated flameholder, PIV was used to study flow fields of V-gutter and integrated flameholder under both non-reacting and reacting conditions. PLIF, high-speed cameras, and TDLAS were adopted to capture OH distribution, flame structure, and temperature distribution. Comparative analysis of flow fields, combustion characteristics and flame stabilization mechanisms were analyzed. Results show that heat release increases adverse pressure gradient, which can enlarge the recirculation zone size and recirculation rate compared to non-reacting flow field. The flames of both flameholders exhibit symmetrical structures distributed near the shear layers. The blockage ratio dominates the non-reacting flow field, while the expansion angle dominates the reacting flow field, which can further increase the adverse pressure gradient under reacting condition. The V-gutter flameholder demonstrates better fuel/air mixing and larger recirculation than the integrated flameholder. The combustion performance of the integrated flameholder is inferior to the V-gutter flameholder, albeit with better flow resistance properties.
Mitumba: second-hand clothing industry in Kenya. A blessing or a curse?
Authors: Kiss Judit
Published: June 2024

Kenya is one of the leading SHC importers in Africa. The aborted import substitution industrialisation, the liberalisation of the economy, and the failure of the domestic textile industry led to the SHC trade surge, which is the direct product of the global (ultra)fast fashion linear business model. SHC industry is beneficial for the economy and the people of Kenya due to job creation, income and revenue generation, and the provision of affordable clothing. However, it has detrimental impact on the environment and the local textile/fashion industry. To maintain the benefits and reduce the negative effects, it is important not to completely eliminate it. In the short run, quantity should be decreased, and the quality should be improved to reduce waste. In the long run, there should be a gradual decrease and eventually elimination of second-hand clothing imports, depending on the revitalization of domestic garment industry.
Rasprava o Meštrovićevim Indijancima u gradu Chicagu
Authors: Kalčić Silva , Mihanović Anđelko
Published: June 2024

Kao dio rasprave formirane oko pokreta Black Lives Matter 2021. godine osnovana je inicijativa Chicago Monuments Project sa zadatkom propitivanja značenja umjetnosti u javnom prostoru, njezine uloge, poruke, forme i medija. Rasprava je zatvorena u ljeto 2022. godine, a dijelom se ticala ideološke pozadine para skulptura Indijanaca Ivana Meštrovića, oblikovanih u New Yorku i Zagrebu 1926. i 1927., a postavljenih 1928. godine u javni prostor grada Chicaga. U medijima su dominirale izjave Dalibora Prančevića i Barbare Vujanović, poznavatelja Meštrovićeva opusa i moderne skulpture u Hrvatskoj, koji su Indijance “branili” s obzirom na njihove formalne kvalitete te bivanje dijelom hrvatske nacionalne umjetnosti, vezujući ih i za širi urbanistički kontekst Chicaga te sagledavajući uvjete i okolnosti njihova postavljanja u javni prostor toga grada, a s druge su strane Nikola Vukobratović i Ivana Hanaček temi pristupali iz vizure postkolonijalnih studija, prema kojoj promicanje narativa o nadmoći i moralnoj superiornosti bijele rase podrazumijeva predstavljanje netočnih i/ili ponižavajućih karakterizacija Indijanaca. Ponajprije je rasprava vođena o tome predstavljaju li Indijanci selektivan i jednostrani pogled na američku povijest te prikazuju li karikaturalno i stereotipno američke starosjedioce, u napetosti između dva suprotstavljena mišljenja stručnjaka i javnosti. Postkolonijalna teorija u središtu svog interesa ima odnos kolonizatora i koloniziranog, kolonijalnog i postkolonijalnog u prošlosti i sadašnjosti, a u slučaju Indijanaca rasprava se ticala homogeniziranih stereotipnih predodžaba o drugima i suptilne konstrukcije subjekata iz skupine antitetično postavljene spram dominantnih pozicija, o kojoj se konstruiraju stereotipi i koje se tim stereotipima poima. Problemski fokus ovog rada je usporedna analiza recepcije skulptura od njihova nastanka do danas.
Contesting Imaginations of Romantic Love
Authors: Gutekunst Miriam
Published: June 2024

Imagination has become an important social practice throughout the world in times of globalization and deterritorialization, as argued by the anthropologist Arjun Appadurai. This development has an effect on the formation of romantic relationships: more and more couples meet across borders. Migration through marriage has become one of the most important legal channels to Europe. In this article, I argue that romantic love can be understood as imagination and, thereby, as a driving force for migration. At the same time, imaginations of romantic love are in the focus of migration control and, consequently, highly contested and shaped by different state actors while travelling across borders.
Football as a Medium for (Transnational) Integration of the Romani People
Authors: Rajković Iveta Marijeta
Published: June 2024

Southeastern Europe is home to numerous Romani communities, each distinctive in their own way depending on their country of origin and the time of immigration, language, customs, religion etc. Based on multi-sited ethnographic research (in the Republic of Croatia, the Republic of Slovenia and the Republic of Serbia), this paper discusses the role of football (professional, amateur and recreational) in the integration of the Roma people. Considering the size and diversity of Romani communities, research results show that football, as the most popular sport, enables easier social integration into the ethnic community on the local and transnational levels. Various football activities (minority football camps, tournaments) are initiated and organized by the Roma community itself. Although the Roma people legally enjoy full civil rights, football serves as a means to reduce discrimination, inequalities, poverty and social exclusion. In order for young Roma to train in clubs, they have to attend school regularly, which results in economic integration. This research also contributes to the creation of public integration policies which are implemented by the very minority and immigrant communities working transnationally.

Na kraju se rada utvrđuje kako je davoračko božićno šetano kolo sudjelovalo u izgradnji i čuvanju kolektivnoga identiteta zajednice.
TO THE PROBLEM OF FORMATION OF CROSS-CULTURAL COMPETENCE OF FUTURE TOURISMOLOGISTS
Authors: DUDKA Tetiana
Published: June 2024

The article analyzes the phenomenon of “cross-cultural competence” in terms of interdisciplinarity. The ability to establish contact under the conditions of cross-cultural differences in everyday life has been problematized. The task is quite complex and requires an appropriate level of training, especially education. The importance of the latter point has been reflected. Western scholars have focused on the idea that interculturally centered learning and education are quite important in the formation of cross-cultural competence. It is emphasized that interculturally centered learning actualizes the increase of knowledge and contributes to the expansion of a range of inocultural interactions at the interpersonal level. The effectiveness of such a mechanism is traced at the level of “absorption” of an individual by the multicultural environment, which is expected to lead to an increasing accumulation of knowledge in the process of close communication with the bearers of different cultures and traditions. It is worth noting that the anti-discriminatory environment of personal growth, which promotes all manifestations of tolerance and humanity at all levels, is especially important in this aspect. The need for the individual to master appropriate models of behavior in dialogue with representatives of different cultures is undoubtedly decisive in achieving success in the process of close communication with foreigners.
The extrapolation of theoretical training of a modern student to professional education for future life in society is often quite different. It is a consequence of the separation of the purpose of employment from current social and cultural tasks. Overcoming existing educational drawbacks is necessary to shift to more complex substantiations of the theoretical material. It can be done by employing the formulation of such problematic tasks that prompt a student to think, reconsider, and reproduce the reconsideration to solve problematic situations. The construction of an algorithm of such theoretical situations must contain some basics of rhetoric, complexity, and variability. This approach to business is especially valuable; it can be productive for the training of future managers at the pedagogical university. It will increase prudence in making important managerial decisions.

Breaking Boundaries
Authors: Setiyono Joko , Pratomo Eddy
Published: June 2024

This thought-provoking paper explores the intriguing issue of Indonesia’s limited geographical jurisdiction concerning extradition treaty implementation. Extradition, the process of returning fugitives to face justice, is frequently impeded by complex legal obstacles stemming from a country’s membership in the United Nations and commitment to human rights principles and values. Due  to their legal jurisdiction or concerns regarding human rights violations, many nations are not obligated to deliver over suspects, posing a unique difficulty for Indonesia. Nevertheless, there is optimism. International cooperation and the development of extradition agreements can serve as a road map for nations seeking to enhance their extradition practices. Countries can negotiate multilateral or regional agreements that satisfy the concerns and interests of all parties by comprehending the complexities of the extradition process, such as the list of extraditable offences and customary international law. Our paper suggests that nations investigate legal models and extradition treaties that offer viable solutions for overcoming these obstacles. By collaborating and sharing information, we can surmount obstacles to justice and ensure that fugitives face the consequences of their actions, regardless of where they hide.

Published: June 2024

The article aims to determine the general principles of guaranteeing human rights and freedoms during the the investigating judge’s examination of motions of pre-trial investigation bodies and prosecutors for permission to conduct covert investigative actions. The subject of the research is the general principle of guaranteeing human rights and freedoms during the consideration of motions to conduct covert investigative actions by investigating judges and the problems of regulation of these issues within criminal procedure legislation. The article uses general scientific and unique research methods, such as comparative, formal, dogmatic, and dialectical. The study results allowed us to determine the areas of improvement of criminal procedural legislation on motions to conduct covert investigative actions. The need for ensuring human rights and freedoms require such actions. Based on the study results, proposals were made to amend the criminal procedure legislation on the motions for investigative actions. In this regard, the incompleteness of regulations requires appropriate amendments to the Criminal Procedure Code of Ukraine, as proposed by the authors. It is substantiated that implementing these changes will ensure sustainable and effective law enforcement practice in the field of organization and conduct of covert investigations, reduce inconsistencies, and ensure uniformity of approaches to determining sufficient and necessary grounds for interference in private communication.
dignidad y la reparación del daño inmaterial en la Corte Interamericana de derechos humanos
Authors: Ratti Florencia
Published: June 2024

En este trabajo se aplica la metodología de análisis jurisprudencial dinámico para reconstruir una fórmula usual de la Corte Interamericana de Derechos Humanos (Corte IDH) que vincula la reparación del daño inmaterial con la restauración de la dignidad humana. Para tal fin, se identifica cuál es la primera sentencia en la que la fórmula aparece, en qué escenarios fácticos se replica y cómo va evolucionando a lo largo de la jurisprudencia del tribunal interamericano. Se evidencia que aquella fórmula es el germen de un rotundo cambio jurisprudencial de la Corte IDH en materia de reparaciones, que no tiene parangón en ningún otro tribunal internacional y que ha despertado algunas resistencias.

Foram avaliados 10 adultos de ambos os sexos com média de idade (50,8 ± 8,0) anos inseridos em um programa de iniciação a natação. Foi aplicada a escala de motivação para o esporte (SMS), para averiguar os níveis da motivação entre os aprendizes. Os resultados evidenciaram que os adultos inseridos no programa de iniciação a natação apresentaram maiores índices de motivação intrínseca (para conhecer 6.0 ± 2.9), (para atingir objetivos 6.1 ± 2.2) e (experiências estimulantes 5.7 ± 2.6). A respeito da dimensão motivacional extrínseca, a (introjeção 6.5 ± 2.5), apresentou maior relevância. Os adultos aprendizes demonstraram altos níveis de motivação intrínseca, porém a pressão criada pelo próprio aprendiz (introjeção), em querer aprender a nadar com rapidez, nos faz repensar a forma que o treinador deverá conduzir a programação de ensino pautada em aspectos pedagógicos e psicológicos divididos por etapa (estabelecimento de metas), para que o aprendiz consiga exibir rendimentos ótimos ao longo do processo de ensino da natação.

Published: June 2024

Лазерное излучение желтого диапазона длин волн находит широкое применение в офтальмологии благодаря своей эффективности и уникальным свойствам. Существующие сегодня коммерческие медицинские лазерные установки обладают малой импульсной мощностью и рядом других недостатков. Желтый лазер на неоне с длиной волны 585,3 нм может быть предложен в качестве альтернативы.В работе представлены результаты экспериментальных исследований пеннинговского неонового лазера с накачкой импульсным индукционным продольным разрядом. В качестве активной среды использовалась газовая смесь Ne–H2в разных соотношениях. В экспериментах форма и длительность импульсов излучения сильно зависели от соотношения компонент Ne–H2, позволяя получать как одиночные, так и сдвоенные импульсы общей длительностью от 30 до 100 нс на полувысоте. Энергия генерации импульсов излучения достигала20 мкДж, что соответствовало импульсной мощности 200 Вт. Лазерный пучок в поперечном сечении имел форму, близкую к кругу, с расходимостью не более 2 мрад. В дальнейшем при реализации импульсно-периодического режима работы с частотой повторения импульсов до 100 Гц индукционный неоновый лазер может применяться в различных областях, в том числе в медицине.

Laser radiation in the yellow wavelength range is widely used in ophthalmology due to its effectiveness and unique properties. Commercial medical laser systems existing today have low pulse power and other disadvantages. A yellow neon laser with a wavelength of 585.3 nm can be proposed as an alternative. This paper describes the experimental study of a neon laser pumped by a pulsed inductive longitudinal discharge. A Ne–H2gas mixture with various ratios is used as the active medium. The shape and duration of the lasing pulses strongly depend on the ratio Ne : H2, providing both single and double pulses with a total duration of 30 to 100 ns (FWHM). The generation energy reaches 20 mJ, which corresponds to a pulse power of 200 W. The cross-section of the laser beam has a shape close to a circle, with a divergence less than 2 mrad. Further, with implementing a pulse-periodic operating mode of an induction neon laser with a pulse repetition rate of up to 100 Hz, it can be used for various applications, including in medicine.

В ходе технологического развития общества неизбежно возникает проблема нарушения экологического состояния окружающей среды, например в водоемах. Для своевременного реагирования на изменения концентраций различных загрязнителей в природных водоемах необходимо разработать экспрессный дистанционный метод. Создание такого метода возможно на основе спектроскопии комбинационного рассеяния света, однако в ходе разработки возникает большое количество различных сложностей, в частности касающихся способа предобработки полученных данных. В настоящей статье представлены результаты применения методов машинного обучения для разработки дистанционного метода определения по спектрам комбинационного рассеяния света типа и концентрации растворенных ионов в водных средах. Использование искусственных нейронных сетей позволило идентифицировать и одновременно определить концентрации каждого из восьми ионов (Zn2+, Cu2+, Li+, Fe3+, Ni2+, NH4+, SO42, NO3–) в многокомпонентной водной смеси с погрешностями, удовлетворяющими потребностям экологического мониторинга природных и сточных вод. Обнаружено существенное влияние способа предобработки спектров комбинационного рассеяния на результат решения обратной спектроскопической задачи. Полученные результаты могут использоваться для решения многопараметрической обратной задачи качественного и количественного определения ионов в воде.

Теоретически исследовано распространение излучения волоконного иттербиевого лазера с длиной волны 1,07 мкм в прессованных микропорошках из прозрачных полупроводниковых и диэлектрических материалов (ZnSe, MgF2, CaF2, SiO2, BaF2, MgAl2O4, Al2O3, Nd:Y2O3, YSZ и TiO2), показатели преломления которых находятся в диапазоне 1,38 ¸ 2,48. В результате расчетов установлено, что сочетание рассеяния и интерференции излучения в среде из частиц диаметром порядка микрон приводит к усилению интенсивности излучения в локальных участках среды на один-два порядка по сравнению с интенсивностью падающего излучения. Показано, что с ростом показателя преломления материала частиц это усиление возрастает. По нашему мнению, в подобных локальных максимумах запускаются как нелинейные механизмы поглощения лазерного излучения, приводящие к забросу электронов в зону проводимости, так и процессы ударной ионизации, приводящие к лавинообразному росту концентрации электронов в этой зоне. В результате материал начинает нагреваться вплоть до абляции.

Micropowders made of transparent semiconductor and dielectric materials (ZnSe, MgF2, CaF2, SiO2, BaF2, MgAl2O4, Al2O3, Nd:Y2O3, YSZ, and TiO2) are theoretically studied. The refractive indices of these materials are in the range 1.38 ¸ 2.48. As a result of calculations, it is found that the combination of scattering and interference of radiation increases its intensity by one or two orders of magnitude compared to the intensity of the incident radiation in a medium of particles several microns diameter. It is shown that this enhancement increases with the refractive index of the particle material. In our opinion, both nonlinear mechanisms of laser radiation absorption and avalanche ionization lead to an increase in the electron concentration in such local maxima. As a result, the material begins to heat up to the point of ablation.

Представлены результаты численного моделирования одного из наименее исследованных эксимерных лазеров – лазера на молекуле KrCl. Моделирование проводилось в 1D-приближении, где потоки лазерного излучения рассчитывались вдоль оптической оси между плоскопараллельными зеркалами, а система кинетических уравнений и уравнение Больцмана решались в каждом поперечном слое активной среды. Получено хорошее согласие теоретических данных с результатами работы KrCl-лазера серии EL. Численно показано влияние ширины разряда возбуждения на энергетические характеристики лазера. Предложенная модель и полученные оценки могут быть использованы как инструменты оптимизации начальных параметров при разработке более мощных лазерных установок.

The paper presents the results of numerical simulation of one of the least studied excimer lasers, a KrCl molecule laser. The simulation was carried out in a 1D approximation, where laser radiation were calculated along the optical axis between plane-parallel mirrors, and the system of kinetic equations and the Boltzmann equation were solved in each transverse layer of the active medium. The theoretical data well agree with the results for the EL series KrCl laser (HCEI SB RAS). The effect of the excitation discharge width on the energy characteristics of the laser is numerically shown. The suggested model and the obtained estimates can be used as tools for optimizing initial parameters when developing more powerful laser systems.
Exploring Theories and Social Policy Changes During COVID-19 Pandemic
Authors: Mäntyneva Päivi
Published: June 2024

The COVID-19 pandemic presented unprecedented challenges to the capacity of developed welfare states to meet emerging needs. In its initial year, the pandemic prompted a wave of new social policy programmes and modifications to existing ones. This study empirically investigates the applicability of various social theories in elucidating the dynamics of social policy changes during the COVID-19 crisis.
Reflective analysis employs Hegelian dialectics as a methodological framework on established theories, including welfare regime theory, path dependence theory, path creation, and incorporates contemporary perspectives such as capability theory. The aim is to reflect and discern what these approaches explain and how these theoretical paradigms account for the observed shifts in social policy dynamics.
The paper builds on previously published studies focused on the dynamics of persistence and change, mitigation and prevention, divergence and convergence, and continuity and irruption in social policies implemented in response to the pandemic. The article also contributes at developing a theoretical and methodological reflective approach to examine social policy changes in multiple contexts.

Published: June 2024

Introducción: A partir del Boston Carpal Tunnel Questionnaire, se desarrolló una escala corta de 6 ítems llamada Six-Item Carpal Tunnel Symptoms Scale (CTS-6). Objetivo: Evaluar la CTS-6 para detectar pacientes con neuropatía periférica del nervio mediano con criterio quirúrgico. Materiales y Métodos: Se realizó un estudio descriptivo prospectivo observacional en un grupo de pacientes con diagnóstico clínico de síndrome del túnel carpiano. Se utilizó la CTS-6, y se corroboró el diagnóstico mediante electromiografía. Posteriormente, los pacientes fueron operados. Se analizaron las diferencias en el puntaje de la CTS-6 entre los distintos niveles de gravedad determinados por electromiografía. Resultados: Se analizaron 106 pacientes. El 20,75% tenía síndrome del túnel carpiano bilateral. Se evaluaron 126 manos. La mediana del puntaje de la CTS-6 fue de 21 (mín. 16,5; máx. 26). Según los resultados de la electromiografía, el 24,22% de los casos de síndrome del túnel carpiano eran graves. Al comparar el puntaje de la CTS-6 según la gravedad del síndrome del túnel carpiano evaluada por electromiografía, la mediana del puntaje de la CTS-6 fue de 16,5 en los casos leves, de 21 en los casos moderados y de 26 en los casos graves. Conclusiones: El puntaje de la CTS-6 fue mayor en los pacientes con síndrome del túnel carpiano grave según la electromiografía. Esto plantea la hipótesis de que podría ser útil como herramienta diagnóstica no invasiva en el síndrome del túnel carpiano para definir pacientes que se beneficien con el tratamiento quirúrgico.
Comportamiento sísmico de edificios irregulares en planta considerando sistemas de aislación con excentricidad de rigidez
Authors: Garrido Cesar , Fernandez-Davila Victor
Published: June 2024

El objetivo de la presente investigación es evaluar el efecto de los parámetros dinámicos del sistema de aislación (el grado de acoplamiento torsional [Wb], el periodo de vibración [Tb],  la razón de amortiguamiento crítico [xb] y la excentricidad de rigidez de la base de aislación [erb]) en el comportamiento torsional de una familia de edificios con seis pisos y aislados en la base de concreto armado, considerando las excentricidades de rigidez o masa (er o em, respectivamente) en la superestructura. Estas modifican su comportamiento estructural ante sismos severos e incrementan los desplazamientos laterales y las derivas de manera significativa. Para ello, se realizó un análisis no lineal tiempo-historia a cada modelo estructural, por lo que estos se sometieron a un conjunto de siete registros de aceleraciones sísmicas, medidos en la costa de Perú y Chile, los cuales fueron escalados según el espectro de diseño de pseudoaceleraciones vigente en Perú.
Como respuestas globales de interés, se consideran los desplazamientos laterales máximos y las derivas de entrepiso. Así pues, se observó que el efecto de em generó mayores amplificaciones en los desplazamientos laterales y derivas que er. Similarmente, el parámetro erb fue muy influyente en el comportamiento torsional de los edificios aislados con em y er, pues amplificó los desplazamientos laterales hasta en un 50 %. Además, el parámetro Tb impactó notablemente las derivas de entrepiso, ya que las redujo hasta en un 55 %. Por otro lado, los parámetros Wb y xb fueron poco influyentes en dichas respuestas.

Az okoseszközök jelenléte mindennapjaink szerves része. Használatuk gyakorta megzavarja szemtől szembeni társas érintkezéseinket, mely jelenséget McDaniel és Coyne (2016) találóan a magyarul is intuitíven jól értelmezhető technoferencia kifejezéssel írták le. Téma-összefoglaló tanulmányunk empirikus kutatások áttekintésén keresztül mutatja be a technoferencia fogalmát és relevanciáját. Az okoseszközök által megzavart társas interakciók jellegzetességeit kapcsolati, párkapcsolati, szülő-gyermek kapcsolati, valamint munka-magánélet kontextusában tárgyaljuk. Összességében megállapítható, hogy a technoferencia minden életkorban jelentős rizikófaktor a társas kapcsolatok minősége és a mentális egészség szempontjából. A felsorakoztatott munkákhoz kapcsolódóan kitérünk a téma gyakorlati relevanciáira, és áttekintjük a további lehetséges és szükséges kutatási irányokat.
