Published: July 2024

The increasing demand for wedang uwuh during the pandemic requires Weeka Wedang Uwuh as a producer to be quick and responsive in meeting demand. Competition for sales of wedang uwuh is currently quite tight because there are more and more wedang uwuh producers. One way to anticipate current business competition, especially in the herbal beverage industry, is to try to manage the resources owned by SMEs, including labor. The right number of workers will guarantee product availability and also provide minimum costs for labor costs. This research aims to provide suggestions for determining the optimal number of workers in order to minimize labor costs. ToC is a problem solving approach that focuses on eliminating constraints using available methodologies. Therefore, this approach is very suitable for eliminating obstacles at Weeka Wedang Uwuh in order to determine the optimal number of workers. To support the TOC approach, the Dynamic Program method will be applied to the obstacle removal step. The optimal number of workers in UKM Weeka Wedang Uwuh will be obtained by reducing 5 (five) workers in the Wedang Uwuh packing section. The savings that occurred during the research time period were Rp. 21,500,302.00 compared to expenses if it had the current number of workers.

Published: July 2024

With its diversity in ethnicity and religion, some parts of Indonesia tend to be vulnerable to conflicts. This research aims to reveal the practice of religious tolerance and the active role of interfaith women in maintaining religious tolerance through daily dialogue. It emphasizes the significant participation of interfaith women in fostering religious tolerance. This study collected data from interfaith women in the Fatubesi subdistrict area of Kupang City using interviews and observation. The results show that interfaith women in Fatubesi, especially in the Oeba traditional market, live in harmonious and peaceful relationships. They have practiced the spirit of sisterhood and friendship in their daily encounters. Even though they are rarely involved in formal dialogue, women are active in a dialogue of life through daily interactions in informal spaces. They are connected in solidarity through openness, acceptance, respect, and helping one another. Furthermore, interfaith women are active peacekeepers through their activities of sharing food and other basic needs in their neighborhoods and during their religious celebrations. Therefore, the activism of interfaith women in the Fatubesi area is a practice that goes beyond religious tolerance.

Relevance. Antibacterial drugs are widely used to treat and prevent infections of the upper and lower respiratory tract. The large-scale and unjustified use of antimicrobials to treat these infections has led to the emergence of resistance in most pathogens. The aim. To study antimicrobial susceptibility testing to erythromycin and azithromycin of strains of B. pertussis isolated in Russia. Materials & Methods. The research included 165 strains of B. pertussis isolated in January 2014 to June 2020. Antimicrobial susceptibility to erythromycin and azithromycin was determined by disk diffusion method and MIC test (HiMedia Laboratories Pvt. Limited, India). The A2047G mutation in the 23S rRNA gene was detected by PCR and subsequent sequencing. Results. Disk diffusion zone diameters for erythromycin in the studied strains ranged from 25 to 62 mm (median 44 mm) and disk diffusion zone diameters for azithromycin ranged from 22 to 80 mm (median 50 mm). Isolates with growth inhibition of more than 42 mm in diameter after 7 days of incubation were considered as susceptible. Among the studied strains, 57 (34.5%) were resistant to erythromycin and 23 (13.9%) to azithromycin. Then, MIC of erythromycin and MIC of azithromycin, respectively, were determined for these 57 and 23 strains using the MIC test. The comparison group included 79 isolates that were classified as sensitive to erythromycin (n = 31) and azithromycin (n=48) according to the results of the previous study. A MIC value of 0.12 μg/ml was considered as the cut-off for susceptible strains. All isolates were fully susceptible to erythromycin (MIC ≤ 0.01 μg/ml, median MIC 0.001 μg/ml) and azithromycin (MIC ≤ 0.01 μg/ml, median MIC 0.0001 μg/ml). An A-to-G mutation was not found at position 2047 in the 23S rRNA gene in 80 isolates that had a diameter of growth inhibition zone less than 42 mm. Conclusion. This study demonstrates no significant decrease in the susceptibility to erythromycin and azithromycin among B. pertussis strains isolated in Russia in 2014–2020. The studied B. pertussis strains exhibit a homozygous phenotype for macrolide resistance.

Published: July 2024

Relevance. Serological monitoring of the state of the population's immunity to the rubella virus is one of the key elements of epidemiological surveillance of the infection, which makes it possible to assess the effectiveness of vaccine prevention, including the level of protection of the population from this infection. This article presents a comprehensive analysis of the results of this event in Russia for the period from 2015 to 2022 in individuals vaccinated against this infection, based on data from reports from regional centers and existing statistical models. The aim. To carry out a comprehensive analysis of data on serological monitoring of immunity among indicator groups of the population to rubella virus in the Russian Federation for the period from 2015 to 2022, taking into account the incidence and peculiarities of immunization tactics. Materials and Methods. Serological monitoring was carried out using standardized test systems and techniques, which ensured comparability of data throughout the entire study period (2015-2022). The contingent for the examination was selected with documentary confirmation of the fact of vaccination in the age groups 3–4 years, 9–10, 15–17, 25–29, 30–35 years. Only persons aged 40 years and older were examined without taking into account the vaccination history Results and Discussion. The conducted study confirmed a sufficient, stable level of immunity to the rubella virus in most age groups and regions of the country, which indicates the effectiveness of vaccination and the preservation (stabilization) of the infection elimination process. The slight increase in the average proportion of seronegatives among adults 30–35 and 40 years and older, revealed in the analysis, compared with other groups, requires further observation and clarification of the causes. Conclusions. The study confirmed the high level of immunity to rubella virus among the population of the Russian Federation, which indicates the effectiveness of the current program of vaccination against rubella infection and the infection elimination program. However, groups of the population have been identified, among which there is a slight decrease in the level of immunity, which requires additional attention from health authorities to maintain a stable rubella elimination status in the country. The results of the study will be used as additions to national and regional strategies aimed at maintaining the rubella elimination status.

Chemical and Mechanical Soil Stabilization Techniques for Foundations
Authors: Chavez Torres Jose Luis , Tugen Feng , Zhang Kunyong , Gonzalez Chavez Maria Alejandra
Published: July 2024

Introduction: The geotechnical study is crucial for foundation design and herein the feasibility of stabilizing soil from Quillollaco Formation in Loja, Ecuador with quicklime. Methodology: Laboratory tests followed ASTM standards. Unaltered soil samples were extracted at depths ranging from 2,00 to 3.00 m and fed quicklime at varying percentages (13,00 to 21,00% and 3,00% for quicklime) during curing periods of 7 to 28 days. Before obtaining results, the soil was classified by primary classification. Laboratory tests included Atterberg limits, Standard Proctor, unconfined compressive strength and permeability.
Results: Consequently, the results indicated that the soil is primarily clay with low plasticity. Although the addition of quicklime increases plasticity and compressive strength, the improvement is minimal and varies with dosage and cure time. Greater compaction and workability are observed with lower quicklime contents. Regarding permeability, moderate to high improvement is recorded with quicklime addition, suggesting enhanced drainage capacity. Disscusion: Stabilization of quicklime soil may improve some geomechanical properties, but its effectiveness and profitability could be limited, especially in clay soils of low plasticity. Emphasis is placed on the need to consider soil stabilization alternatives that are efficient and sustainable from economic and environmental points of view.

Published: July 2024

Motives: Local authorities are seeking new approaches to development, with a strong emphasis on multifunctional development. Taking into account the state of the natural environment, they need to implement various activities that effectively reduce anthropogenic pressure. Poland’s membership in the EU requires the implementation of the European Green Deal. The neighbouring Polish and Ukrainian regions of Lublin and Lviv, which share similar environmental conditions and a common cultural heritage, were chosen for this study. The Polish border regions have the potential to serve as an important model for Ukrainian border regions as they strive to integrate into the European Union. This  paper provides an overview of development and environmental support policies, as well as in-depth case studies, to establish a basis for assessing the sustainable functioning of rural municipalities and territorial partnerships. Aim: This study examined supra-local strategic documents concerning environmental protection and rural development in Polish and Ukrainian municipalities. Their socio-economic situation was characterised, and the goals and activities proposed under their environmental protection programmes and local development strategies were identified. Results: Based on the research findings, a proposal was formulated for implementing systemic solutions in the development of strategic plans to ensure that local strategies become fundamental tools for implementing measures that support environmental protection and sustainable development.
Identifying and hierarchizing factors that affect the choice of transport routes in land ferry transport chains
Authors: Kotowska Izabela , Łapko Aleksandra , Jendryczka Violetta
Published: July 2024

Motives: The choice of a transport route has long been the subject of research because it is regarded as one of the most crucial decisions in transport organizations. However, there is a lack of studies addressing this issue in the context of land-ferry supply chains, where two transport modes have to be integrated. Therefore, analyses of multimodal transport should involve a holistic approach to account not only for seaborne transport, but also for the land leg before and after the ferry trip. This knowledge gap should be urgently addressed due to the importance of land-ferry supply chains in the transport system. Aim: The aim of this study was to identify and hierarchize factors that determine the choice of a multimodal transport route combining ferry and road transport. Results: The factors that determine the choice of ferry routes were identified and hierarchized according to their importance as primary, supplementary, and additional routes. The study demonstrated that the cost and time of transport are the main determinants in the decision-making process, with time being marginally more important than cost.

Authors: Budiono Satwiko ,   National Research and Innovation Agency, Indonesia, Jaya Taufan ,   Universitas Hasanuddin, Indonesia
Published: July 2024

Limola is one of Indonesia’s endangered languages, makingit imperative to pass on Limola culture and language to a younger generation. The Limolalanguage revitalization program in Sassa Village, Baebunta District, North Luwu Regency, South Sulawesi Province seeks to preserve the Limola language and culture by teaching the younger generation Limola drama, songs, and poetry. Therefore, this study evaluates the key performance indicators of Limola culture and language learning in the revitalization program to identify the identity of the To Limola society after learning Limola culture and language, and (2) evaluate the implementation of the Limola language community-based revitalization. This study used a descriptive qualitative approach that involved desk study data collection techniques and in-depth interviews with the participants and instructors from the Limola language revitalization program. A sociolinguistic in termsof language and identity research approach was taken to analyzethe data and explore the local content in the language learning materials. The data analysis was also based on the CIPP (Context, Input, Process, and Product) evaluation model and language progress indicators to evaluate the implementation success. The results revealed that the Limola revitalization language learning materials have local content that strongly reflects the identity of the To Limola society. While the Limola language revitalization participants learned both the Limola language and culture, the implementation did not appear to have had a significant impact on increasing the interest of the younger generation in using the Limola language.
An der Seite der Überlebenden. Therapiezentren für Folterüberlebende als Produkt der internationalen Solidarität
Authors: Rauchfuss Knut , Cleusters Christian , Schmolze Bianca
Published: July 2024

1983 wurde in Kopenhagen das weltweit erste Rehabilitationszentrum für Folteropfer eröffnet. Bereits vorher hatten einzelne chilenische Aktivist*innen im europäischen Exil kleinere psychosoziale Zentren ins Leben gerufen. In den Diktaturen des Cono Sur und Mittelamerikas, aber auch in anderen Teilen der Welt hatten Menschenrechtsaktivist*innen vor Ort ebenfalls begonnen, den Kampf um Befreiung und die psychosoziale Versorgung von Überlebenden sozialpolitischer Traumatisierungsprozesse zusammenzudenken und zu praktizieren. Eine maßgebliche Rolle spielte dabei die Befreiungspsychologie, die über die internationale Solidarität auch die Gründer*innen der ersten europäischen Zentren erreichte. Der Aufsatz zeichnet diese Verflechtungsgeschichte von Befreiungskämpfen, Menschenrechtsarbeit, internationaler Solidarität und der Gründung von Therapiezentren nach. Bereits zu Beginn war die Arbeit im Kampf gegen Folter dabei sowohl an der individuellen und sozialen Rehabilitierung der Überlebenden ausgerichtet, als auch an der strafrechtlichen Verfolgung der Täter*innen. Heute haben jedoch viele der zwischenzeitlich in zahlreichen deutschen Städten gegründeten Zentren diese Orientierung gegen ein Selbstverständnis als reine Versorgungseinrichtung eingetauscht. Zusätzliches politisches Engagement fokussiert allenfalls auf die Unterstützung traumatisierter Flüchtlinge in Deutschland. Die Autor*innen plädieren daher für eine Wiederbelebung der internationalen solidarischen Parteilichkeit in deutschen Psychosozialen Zentren und die Rekonstruktion eines Selbstverständnisses, Teil der internationalen Menschenrechtsbewegung zu sein.
ACOUSTIC OSCILLATIONS IN A DEEP WELLBORE GENERATED BY ITS ELASTIC DEFORMATIONS IN THE FIELD OF SEISMIC WAVES FROM A REMOTE SOURCE*2
Authors: Didenkulov I.N. , Malekhanov A.I. , Chernov V.V.
Published: July 2024

This paper analyzes the possibilities of an original approach to constructing a distributed seismic monitoring system based on a stationary seismoacoustic propagation path of a sounding signal. Such a stationary path can be formed by a powerful source of low-frequency vibration oscillations located on the earth's surface, and a signal recording point located tens (or more) kilometers away from it. It is proposed to use hydroelectric power station units as a powerful vibration source, which have a typical mass of several hundred tons and create vibration signals in the environment of the earth's rocks with characteristic frequencies from a few to one to two tens of Hz (including harmonics), and as a registration point – deep well equipped with the necessary measuring instruments. To record low-frequency longitudinal waves in the thickness of the earth's rocks surrounding the well, a fairly simple and effective method is proposed, based on the use of an extended wellbore as a distributed seismic antenna and a microphone installed on the upper section of the well. The work shows that stresses in the field of a longitudinal seismic wave, acting on the wellbore, cause a change in its diameter, which in turn leads to the occurrence of oscillations of the column of liquid filling the wellbore at the frequencies of the seismic waves determined by the source. A specific scheme for implementing the discussed approach is considered using the example of the Nizhny Novgorod hydroelectric station and the Vorotilovskaya deep well located at a distance of about 40 km. Quantitative estimates and experimental data demonstrating the possibilities of using the corresponding stationary route are presented.
DYNAMIC CONTACT PROBLEMS FOR COMPOSITE MEDIA WITH ANISOTROPIC STRUCTURE

Published: July 2024

The paper for the first time develops a method for solving dynamic contact problems on the effect of a rigid die in the form of a strip of finite width on a layered anisotropic composite. By applying Mandelstam's principle of marginal absorption, the initial boundary value problem is reduced to a boundary value problem with absorption having a single solution. The symbol of the integral equation has no singularities on the real axis. The contact problem is reduced to solving a two-dimensional integral equation with a difference kernel. The application of the Fourier transform along the coordinate along the strip reduces the integral equation to a one-dimensional one containing a free real parameter of the Fourier transform. Integral equations with an exact solution are introduced, with symbols majoring above and below the symbol of the integral equation. Using the factorization method, the initial integral equation is reduced to two integral equations of the second type, the operator of which turns out to be compressive with a sufficiently large bandwidth. By applying the Newton–Kantorovich method to this integral equation, an exact solution of the integral equation is constructed in an operator form. The presence of the majorant symbol of the integral equation allows us to obtain an upper and lower estimate of the constructed exact solution of the integral equation containing the parameter of the Maldenstam limit absorption principle. After that, in the constructed solution, this parameter rushes to zero from above. The solution of the integral equation is obtained in an analytical form and allows us to identify all its singular features. The result is important when searching for harbingers of an increase in seismicity in mountainous areas. The method is applicable in all cases when it is possible to construct a Green function for a non-mixed boundary value problem in a layered anisotropic composite.
NON-STATIONARY WAVES IN A FUNCTIONALLY GRADED VISCOELASTIC PLANE-PARALLEL LAYER2
Authors: Pshenichnov S.G.
Published: July 2024

The propagation of nonstationary disturbances in a plane-parallel layer of infinite extent, which arise as a result of normal dynamic loading of one of its surfaces when the other surface is stationary, is investigated. The material of the layer is assumed to be functionally graded and, at the same time, viscoelastic. The hereditary properties of such a material are taken into account using linear integral Boltzmann–Volterra relations with regular kernels in the form of partial sums of the Prony's series. The peculiarity of this work is that here the parameters of the relaxation kernels are considered continuous functions of the transverse coordinate in the same way as other physical and mechanical characteristics. A method was used for the study, which consists in replacing a functionally graded material with an approximating layered homogeneous structure with continuity conditions at the contact of homogeneous layers. The solution of the nonstationary dynamic linear viscoelasticity problem for a package of plane homogeneous viscoelastic layers is presented in a special form, which greatly simplifies its numerical implementation, especially with a large number of layers with different hereditary properties. This made it possible to successfully apply this method and carry out a series of calculations using an efficient algorithm.
Transient wave processes are investigated in the case when the parameters of a functionally graded material are non-monotonic functions of the transverse coordinate, symmetrical with respect to the middle surface of the layer. A comparison of transient wave processes for different types of these functions is carried out. The convergence of the calculation results with an increase in the number of approximating homogeneous layers with a continuous dependence of the external load on time is confirmed. The significant influence of both heterogeneity and viscosity of the material on nonstationary wave processes has been established.
TRANSFORMATIONAL MODEL OF A PLANE ROD DEFORMATION, RESTRAINED ON DOUBLE-SIDED SLIDING SUPPORTS
Authors: Paimushin V.N. , Shishkin V.M.
Published: July 2024

A linear transformational model of the dynamic deformation of a plane rod is constructed. The end sections of the plane rod are restrained on two-sided sliding supports of finite length, excluding the displacements of the surface points of end sections in the transverse direction. To describe the deformation process of restrained sections of the rod, the S.P. Timoshenko?s shear model is used. For unfixed part the classical Kirchhoff – Love model is used. The conditions for the kinematic coupling of the restrained and free sections of the rod are formulated. Based on the Hamilton – Ostrogradsky variational principle, the equations of motion, the corresponding boundary conditions, as well as the force conditions for the coupling of the sections are obtained in a geometrically linear approximation. Based on the obtained equations of motion, exact analytical solutions of free and forced harmonic oscillations problem of the plane rod were constructed. It is shown that within the framework of the deformation models used, the problems of longitudinal and bending vibrations of the rod are separated. Of these, bending vibrations occurring in a relatively low frequency range are of greatest practical interest. For them, numerical experiments were carried out to determine the three lower natural modes and frequencies of vibrations, as well as the dynamic response during resonant vibrations of a plane rod on the marked frequencies made of a unidirectional fiber composite based on ELUR-P carbon fiber and XT-118 epoxy. A significant transformation of transverse tangential stresses is shown during the transition through the boundaries from the free section of the rod to restrained one. Such transformation due to the difference in deformation models of the marked areas, as well as their pronounced localization in the areas of restrained areas located near the marked boundaries.
Academic bullying as a racialized phenomenon in STEM higher education
Authors: Wang Peiwen
Published: July 2024

While students of color’s experiences of academic bullying from their advisors have been documented in the literature (e.g., Moss & Mahmoudi, 2021), little is known regarding the role that race plays in the normalization and perpetuation of academic bullying within higher education. Utilizing Asian critical theory (AsianCrit) as both the theoretical and analytical lens, this phenomenological study centers five STEM Asian international doctoral students’ experiences of academic bullying through semi-structured interviews. It is found that racialized academic bullying is operationalized by a) legitimizing exploitation through racializing discourses; b) maintaining White supremacy across transnational contexts; and c) intersecting systems of oppression. Implications and recommendations are offered as to what stakeholders can do collectively to address racialized academic bullying towards minoritized students and to combat systemic inequities and oppression.

Welfare e cultura, due piani di azione apparentemente distanti, che si occupano uno dell'essenziale per le persone e l'altro dell'essenza delle persone: ben integrati, possono tradursi in un'azione strategica e programmatica politico-istituzionale di welfare culturale, per il benessere degli individui e delle comunità e per la creazione/riconversione/recupero/valorizzazione di spazi per l'espressione emotiva veicolata dalle arti e dai prodotti culturali.
Urban dimension of Crypto mines dynamics: A spatial approach. USA focus
Authors: De Falco Stefano
Published: July 2024

This work investigates data mining phenomenon in a spatial approach, focused on the United States. The results reveal a predilection of "miners" in areas with low energy costs, but not of a rural type, as it could be expected, but rather in geographical proximity to urban areas where it is easier to reach ICT workers and maintenance and assistance services for data "factories". This closeness, however, often triggers conflictual dynamics.

Authors: Krasilova Yulia , Proskurnia Alina , Vakulenko Oleksandr , Vaskivska Svitlana , Zhadanov Serhii
Published: July 2024

The current article investigates the psychological and social challenges that displaced people face in the context of the Russian-Ukrainian war. The authors focus on the consequences of traumatic experiences, language situations, and the correlation between migrants' aggression and loneliness. The comparative study was concentrated on Ukrainians who relocated to other countries, including Po- land, Germany, and Canada, as well as those who had been internally displaced to Kyiv. The findings indicate a high level of aggression, particularly among men, associated with circumstances and a sense of loss. The factors that con- tribute to adaptation difficulties for Ukrainian forced migrants and immigrants were identified, and it was outlined how the absence of group support and social integration can exacerbate adaptation problems. The article's overall conclusion emphasises the importance of understanding the psychological aspects of dis- placed individuals' adaptation in order to overcome challenges and form a positive image of a country.
Pensare la storia del lavoro domestico. A che punto siamo? Spunti di riflessioni a partire da alcune recenti pubblicazioni
Authors: Capitano Olimpia
Published: July 2024

Nella prima parte dell'articolo l'autrice mostra alcune ambiguità relative alle trasformazioni storiche delle relazioni tra valore, lavoro, genere e domesticità a partire da alcuni volumi recenti e senza pretesa di esaustività a fronte della vasta letteratura esistente. Nella seconda parte dell'articolo, l'autrice riflette sulle principali trasformazioni che hanno riguardato gli studi di storia del lavoro domestico retribuito e di storia del lavoro. In conclusione, si sofferma sul recente intreccio tra questi due filoni e suggerisce alcune direzioni per future prospettive di ricerca.
Écouter le feu. The aftermath of wildfires and the question of rebuilding in high risk fire areas
Authors: Bosselman Peter , Rannou Catherine , Dilet Marc
Published: July 2024

Mega-fires have become frequent in areas around the world. They are no longer limited to areas in the Mediterranean climate. Extreme fires are now burning in Canada and Siberia due to more frequent fire weather conditions. Such conditions are strongly linked to the warming of the earth's atmosphere. In the US the term mega-fires came into use after the 1988 fire at Yellowstone Park. Such fires can permanently transform a landscape into a non-forested habitat. Wildfires are uncontrolled fires that burn in the wildland urban interface. No longer are wildfires a topic of interest only to foresters. Those in the practice of urban design and planning need to take notice. Land-use changes made by local governments have permitted urban development within forested areas and they have further exacerbated fire risks.

Il servizio intende stimolare una ri?essione sulla recente sperimentazione dei Programmi Innovativi per la Qualità dell'Abitare (PINQuA); si apre con la ricostruzione dell'evoluzione, a partire dall'avvio della stagione dei programmi complessi, del quadro delle politiche e degli strumenti sperimentati con riferimento alle questioni dell'abitare e della rigenerazione delle marginalità urbane, provando altresì a esplorare inerzie, apprendimenti e innovazioni insite nella più recente sperimentazione dei PINQuA. Ricostruita la geogra?a italiana dei PINQuA, il servizio approfondisce i punti di forza e di criticità dell'iniziativa a partire dall'osservazione ‘concreta' di alcuni casi particolarmente signi?cativi.
Il PINQuA di Caserta tra continuità e innovazione
Authors: De Biase Claudia
Published: July 2024

Caserta è una città che programma molto e piani?ca poco. Lo strumento urbanistico vigente è ancora il PRG di Beguinot del 1974, ma negli ultimi decenni, grazie alle possibilità offerte dalla programmazione ‘complessa' italiana e dalla programmazione comunitaria, vaste parti di città sono state modi?cate, a prescindere dalla piani?cazione urbanistica. L'articolo analizza il PINQuA di Caserta: si tratta di un progetto ambizioso di rigenerazione urbana di un quartiere periferico, caratterizzato da un grande problema di accessibilità e di scarsità di servizi. Il programma punta a colmare questi de?cit attraverso un sistema complesso di interventi sugli spazi pubblici, sulle attrezzature, sulle connessioni con il resto del tessuto urbano oltre che, naturalmente, sull'housing sociale.
Il divenire dell'urbano: la contemporaneità riscopre l'arcaico. Riabitare l'Alta Gallura
Authors: Decandia Lidia
Published: July 2024

Il saggio, nel riallacciarsi al pensiero di Lefebvre che preconizza già a partire dagli anni '70 il passaggio dell'idea di città circoscritta a quella di ‘campo urbano', esteso all'intero contesto planetario, si concentra sui territori dell'Alta Gallura – una subregione situata nella Sardegna nordoccidentale – per indagare quali forme assuma questo concetto, in divenire, in questo territorio vissuto per secoli ai margini della grande storia. Per farlo, esplora le microforme dell'abitare che si stanno delineando in questi territori e che vedono protagonisti non le società locali, ma soggetti in esodo dalle città consolidate, che riscoprono e reiventano, per rispondere ai propri modelli di vita urbani, le sopravvivenze dell'antico mondo degli stazzi, inserendoli all'interno di una nuova trama di relazioni.

Published: July 2024

Avaliou-se os efeitos de um jogo de tabuleiro educativo sobre os comportamentos de ler e escrever palavras com encontros consonantais e a usabilidade e o engajamento promovidos por ele. Participaram três crianças que não escreviam ou liam palavras com encontros consonantais. Inicialmente testaram-se as relações CD (figura - escrita manuscrita), CB (figura - palavra impressa), BA’ (palavra impressa - nomeação de palavra) e AE (palavra ditada - construção com letras) com as palavras de ensino e generalização. Em seguida, por meio do jogo, ensinaram-se as relações BA’, AA’, BE, AE, AC, BC, BD, AD, HE, GH, AF, BF e HI em que F se refere a soletração oral, G a sílaba falada, H a sílaba impressa e I nomeação de sílaba. Entre as sessões de intervenção realizaram-se sondas e ao final sessões de pós-teste e follow-up semelhantes ao pré-teste. Após o início da intervenção observou-se aumento na porcentagem de acerto para todas as relações, com as palavras de ensino e generalização, indicando que o jogo pode ser usado no ensino de palavras com encontros consonantais. O jogo apresentou usabilidade adequada e os participantes se mantiveram engajados até a 15ª sessão quando se constatou diminuição do engajamento.

Redefining Regional Development: The Case for an ASEAN Development Bank
Authors: Lee Brice Tseen Fu , Sims Juan Pablo
Published: July 2024

Amidst ASEAN's vibrant economic expansion lies an urgent need for a specialized financial institution—an ASEAN Development Bank (ASDB)—to harness and guide this growth. The region's dynamic diversity in development stages presents a unique opportunity for the ASDB to act as the catalyst for economic resilience and regional integration. This urgency is underscored by the potential for the ASDB to provide targeted financial strategies, directly addressing the specific challenges faced by member states. A robust and equitable governance structure will be crucial for the ASDB to facilitate strategic decision-making and sustainable development. The establishment of the ASDB is not just timely but imperative to ensure that ASEAN's economic growth is balanced, inclusive, and sustainable, positioning the region as an integrated, resilient economic powerhouse on the global stage.
