Published: April 2024

Since the first publication of Dubois in 1894, the diagnosis of Homo erectus is based on a list of morphological features established and updated after successive major discoveries made in the 20th century. While the existence and limits of the Homo erectus s.l is still debated, the homogeneity of the Indonesian Homo erectus, which covers a chronological period of ca. 1.5 million years, is also regularly questioned. Most of the studies addressing this question remain focused on the few most preserved specimens, even if a significant number of fragmentary specimens are available which could help to better appreciate the morphological variability of this species. In this present analysis, several unpublished fragmentary frontal (n=6) and occipital (n=9) bones recovered from the Pucangan and Kabuh layers in the Sangiran dome (Central Java) are described, analyzed and compared to the 3D models of contemporaneous (Trinil, Sangiran) and younger (Solo series) Indonesian H. erectus, specimens from Zhoukoudian Lower Cave in China, Dmanisi (Georgia), as well as East African hominins (East and West Turkana, Olduvai). The results help to precise the anatomical characteristics of these isolated human remains and increase our knowledge of Javanese Homo erectus morphological variability.

Currently, the South-Melanesian region shows a wide cultural and linguistic diversity related to a complex history of interaction and peopling episodes. One episode is associated with human groups related to the Lapita culture, originating from South-East Asia and generally considered as being admixed with Papuan groups. These groups colonized the islands of Vanuatu and New-Caledonia around 3000 BP. This episode is quickly followed by a phase of cultural changes generally interpreted as resulting from local differentiations. Another episode, that occurred around 1000 BP, corresponds to the dispersal of the Polynesian groups, amongst which some reached a number of South-Melanesian islands. We examine this pattern of island settlement by the mean of a comparative morphometric study of human mandibles from Vanuatu archaeological contexts representing these three time periods. To this end, we compare ancient phenotypes to the modern variability to investigate the transformation of the Lapita biological entity in Remote Oceania through a diachronic perspective.
A tale of bifaces from southern peninsular India (British Museum and Musée de l'Homme collections): a geometric morphometric and classical approach
Authors: Kunneriath Madhavi , Korisettar Ravi , Gaillard Claire , Chacón Maria Gema
Published: April 2024

Bifacial tools (especially handaxes and cleavers) have played an important role in the Lower Palaeolithic studies trying to decode Acheulean lifeways through them. The methodological approach based on classical metrical analysis, could be insufficient and often subjective, especially in instances of asymmetrical tools, and incorrect orientation for capturing the morphological data. Recent years have seen the application of geometric morphometric methods on lithic tools (2D contours and 3D volumetric forms) as an accurate, efficient and objective method of data collection. This alternative approach has the additional advantage of being both interactive and reversible analytic process, reducing the time and effort in collection of data. Traditionally the museum collections of Palaeolithic artefacts of old surveys and fieldworks, are seldom subject to study due to their incomplete and often doubtful or mixed context. In the current study, both geometric morphometric on 2D contour analysis as well as classical techno-typological analytical methods has been applied to bifaces from Southern Peninsular Indian Palaeolithic kept in the British Museum (London, UK) and Musée de l’Homme (Paris, France). The aim of this study is to highlight the complementary nature of both analytical methods in deciphering and throwing light on the patterns of bifaces (handaxes and cleavers), their technological variability and stability and to identify if there are regional technological trends. The results obtained from both classical analysis and geometric morphometric analysis allow to show that handaxes were highly variable in both the regions while the cleavers show high standardization. While the former approach throws light on the knapping techniques and preferences, the latter complement the results with the shape preferences and variations across regions.
"Oldowan" in the northern Caucasus – archaeology from the seabed or just geology
Authors: Doronichev Vladimir B. , Golovanova Liubov V.
Published: April 2024

The authors discuss the geoarchaeological data indicating that the Oldowan-age assemblages, which are reported during the last years on the Taman peninsula, in the north-western Caucasus, and in Dagestan, in the north-eastern Caucasus, are found in the marine coast environment near the contact with the sea basin, with evidence for the presence of shallow water (in Muhkai II and other localities in Dagestan) or wave activity (in Kermek and other localities on Taman). The marine environment is not reported in any Early Pleistocene archaeological site in either Europe or south-western Asia, or Africa. Moreover, the geological contexts identified in the Early Pleistocene localities in the northern Caucasus correspond to typical conditions for the formation of eoliths or geofacts. The combined archaeological and geoarchaeological indicators strongly suggest that these North Caucasian assemblages most likely represent collections of naturally broken stones that were selected by researchers among fragments of the same rock that is present naturally in these areas.
Chert exploitation and circulation in eastern Lombardy (Northern Italy): a diachronic overview through prehistory
Authors: Bertola Stefano , Lo Vetro Domenico , Schirolli Paolo , Confortini Federico , Malzanni Matteo , Pellecchi Pasquino
Published: April 2024

This work focuses on the Eastern Lombardy Prealps (central Southern Alps), including the Brescia and Bergamo provinces. Knappable lithic raw materials are represented by cherts and radiolarites which are quite common in the Jurassic-Cretaceous sedimentary series. Tectonics played an important role for the preservation of good chert outcrops. Several prehistoric sites are located not far away from the primary lithic sources; in particular we have identified three main areas with good outcrops. South-north mobility along the main valleys is highlighted by the raw materials displacements from the outcrops, situated at the mouth of the valleys, to the north. The Palaeolithic record of the area is very poor. Mousterian sites are generally located near the outcrops. An Epigravettian site is situated far away from the primary sources in the mid-mountain easily accessible by valley routes. A greater mobility is documented in the Mesolithic when also extra-regional cherts (western Trentino) were introduced in the sites. In the Brescia district, starting from the Neolithic and during the Copper age, we observe an increase in the import of very good chert types from the Baldo/Lessini area for specific purposes together with the exploitation of the local resources for domestic use.

The Vagaries of French-Australian Relations Seen Through French Eyes
Authors: BERTI ERIC
Published: April 2024

Eric Berti was Consul-General of France in Sydney from 2012–2015. His opinion piece is in response to that of Ivan Barko in Issue 73, where Barko wrote of the ‘love-hate’ relationship between France and Australia. Berti responds that, while he does not see a ‘love-hate’ relationship, French-Australian relations have always been complex, with both historical and sociological roots. He refers, as did Barko, to the English prism through which Australia has historically viewed France, and to the colonial factor and how this has coloured perceptions. Cultural perceptions and French presence in the Pacific are part of the story as are the connections forged by young French working visa visitors and the long-standing French interest in Australia’s Indigenous people.

La animalización en Hexamerón: la relación persona/aves en la antropología moral de Ambrosio de Milán
Authors: Miranda Lidia Raquel
Published: April 2024

ResumenLos pájaros en Hexamerón, de Ambrosio de Milán, revelan con claridad el lazo conceptual entre animal y ser humano que permite desplegar tanto un discurso moral efectivo como un testimonio de la complementariedad entre individuo e instituciones. El alma sensible de los pájaros se manifiesta en sus comportamientos, que son individuales pero tienen implicaciones sociales: volar, cantar y nadar son actividades corporales, pero con una finalidad trascendente que, además, repercute en la vida de sus familias y sus bandadas. Es así que la analogía que establece el predicador no exige una renuncia total al cuerpo, sino su consagración a los actos sublimes del alma. En pocas palabras, la representación de las aves en Hexamerón ofrece una de las claves interpretativas de la antropología moral que postula Ambrosio en todos sus tratados exegéticos. Por ello, este artículo se ocupa de revisar los rasgos y los sentidos de algunas especies del ámbito aviar en el tratado sobre los seis días de la creación, a partir del análisis filológico de las secciones pertinentes del octavo sermón, con el objetivo de poner de relieve y explicar el valor cristiano de las alegorías entre el comportamiento y los sentimientos de aves y seres humanos y sus relaciones con el mundo antiguo.
AbstractThe birds in Hexameron by Ambrose of Milan clearly reveal the conceptual link between animal and human being that allows to display both an effective moral discourse and a testimony of the complementarity between individual and institutions. The sensitive soul of birds is manifested in their behaviours, which are individual but also have social implications: flying, singing, and swimming are bodily activities with a transcendent purpose that, in addition, have an impact on the lives of their families and their flocks. Thus, the analogy established by the preacher does not demand a total renunciation of the body but its consecration to the sublime acts of the soul. In short, the representation of birds in Hexameron offers one of the interpretive keys of moral anthropology that Ambrose postulates in all his exegetical treatises. For this reason, this paper deals with reviewing the features and meanings of some species of the avian sphere in the treatise on the six days of creation, based on the philological analysis of the relevant sections of the eighth sermon, with the aim of revealing and explaining the Christian value of the allegories between the behaviour and feelings of birds and human beings and their relationships with ancient world.
Francisco de Vitoria, Domingo de Soto, José de Acosta y Bartolomé de Las Casas sobre la fides implicita de los indígenas de América
Authors: Schulz Michael
Published: April 2024

Resumen
El llamado ‘descubrimiento’ del ‘Nuevo Mundo’ obligó a la teología cristiana a discutir con nueva y gran urgencia la posibilidad de salvación para personas que nunca habían oído hablar del Evangelio de Cristo1. Este artículo presenta las respuestas de dos teóricos y dos prácticos, Francisco de Vitoria y su discípulo Domingo de Soto, ambos representantes de la Escuela de Salamanca, y dos misioneros, José de Acosta y Bartolomé de Las Casas. Este escrito presenta a los cuatro autores, en este orden, para mostrar cómo la tesis tan discutida sobre el significado salvífico de la fe implícita (fides implicita) de los indígenas americanos2 recibe una justificación cada vez más consistente, pero también un rechazo —aparente— decisivo en Acosta y Las Casas. Pretendo, sin embargo, desarrollar la tesis de que mientras Acosta y Las Casas tradicionalmente argumentan a favor o presuponen la necesidad salvífica de la fe explícita (fides explicita), ahondan en posiciones a favor de la relevancia salvífica de la fe implícita, y lo hacen –en contraste con Vitoria y Soto– de una manera muy original e innovadora basada en sus experiencias concretas en el Nuevo Mundo, de las que los teóricos Vitoria y Soto carecían. Además, se perfilan los primeros inicios de una hermenéutica intercultural, cada vez más necesaria en un mundo globalizado.
 
Abstract
The so-called ‘discovery’ of the ‘New World’ forced Christian theology to discuss with new and great urgency the possibility of salvation for people who had never heard of the Gospel of Christ. This article presents the responses of two ‘theoreticians’ and two ‘practitioners’, Francisco de Vitoria and his disciple Domingo de Soto, both representatives of the School of Salamanca, and two missionaries, José de Acosta and Bartolomé de Las Casas. This paper presents the four authors in this order to show how the much discussed thesis on the salvific significance of the implicit faith (fides implicita) of the American Indians receives an increasingly consistent justification, but also an –apparent– decisive rejection in Acosta and Las Casas. I intend, however, to develop the thesis that while Acosta and Las Casas traditionally argue for or presuppose the salvific necessity of explicit faith (fides explicita), they delve into positions in favor of the salvific relevance of implicit faith, and do so –in contrast to Vitoria and Soto– in a very original and innovative way based on their concrete experiences in the New World, which the theorists Vitoria and Soto lacked. Moreover, they outline the first beginnings of an intercultural hermeneutics, increasingly necessary in a globalized world.

Published: April 2024

The alchemy of innovation refers to the process of transforming or transforming elements, ideas or processes into something new, valuable and useful in order to achieve progress and development in various fields such as economics, science, technology and business. The term can cover a wide range of activities, including the introduction of innovations, the development of new products, processes or strategies, and the improvement of existing systems in order to achieve more effective results. Given the rapid development of digital technologies and the transformation of business processes, the alchemy of innovation becomes relevant in the context of the search for new strategies and approaches to stimulate the development of the economy and business, of any country. Of course, Ukraine is no exception. The article is aimed at analyzing the modern directions of innovations on the basis of the study of key trends and basic platforms for implementation in the field of development of digital technologies, which will allow to identify and describe the most effective tools, taking into account the domestic specifics and difficulties of implementation in conditions of uncertainty. The study showed that Ukraine's position in the ranking of digital competitiveness in terms of the main components in 2021 is increasing in the categories of "Knowledge," "Technology" and "Future readiness" due to such sub-factors as an increase in total state spending on education, the number of women researchers, increased investment in telecommunications and increased use of big data and analytics. Some digital technologies are not effective for Ukraine because of their complexity of implementation and cost of implementation in conditions of full-scale war. The digital economy sector in Ukraine has the potential to ensure the stability and growth of necessary financial revenues, especially for post-war reconstruction. Digital solutions are of interest not only from a financial point of view, but also strategic, as they can improve the efficiency of the industries in which they are integrated, including government and military sectors. Given the existence of such trends, we consider it promising to further expand, improve the practice of using digital technologies in Ukraine to achieve its economic development.

The article is devoted to the study of the impact of Big Data technology on marketing strategies in the banking and insurance sectors. It examines the role of collecting, analyzing and interpreting large volumes of data in shaping effective marketing strategies, personalizing services and increasing customer satisfaction. The article estimates the challenges and opportunities arising from the implementation of Big Data in banking and insurance. A theoretical study of banking and insurance marketing content has been conducted, aiming to identify their specifics and improvement opportunities through the integration of traditional marketing methods and Big Data technology. Additionally, we have identified and characterized cumulative effect: the combination of data processing capabilities and the use of both structured and unstructured data lead to a fresh perspective on potential clients and can foster the development of innovative banking and insurance services. The potential use of Big Data technology in shaping marketing programs for banks and insurers has been assessed. The potential applications of the technology are considered through several examples. Special emphasis is placed on the creation of a cumulative effect resulting from the integration of Big Data technology into the marketing activities of banks and insurers, which occurs when the capabilities of the technology are combined with traditional marketing methods. The article also focuses on the factors that restrict the use of the mentioned technology: the complexity of processes, a shortage of professionals in the field of Data Science, technical challenges in developing high-quality algorithms, and concerns regarding the use of confidential information and personal data. An assessment of the problem of the influence of all digital technologies on the labor market was conducted using the example of the insurance business. The problem has a transformational and, to some extent, temporary nature. The possibility of utilizing Big Data technology for calculating damages caused by military actions and forming a financial foundation for post-war reconstruction is presented.
Impact of crusher type on coal raw material quality
Authors: Shmeltser Kateryna , Kormer Maryna , Dats Natalia
Published: April 2024

The suitability of coal charge for coking depends significantly on the level of its grinding. At the same time, the quality of the charge deteriorates both large pieces and small ones. The most valuable from this point of view are the 3-0.5 mm size classes. The charge, consisting of coal grains of different sizes and stages of metamorphism, should be thoroughly mixed according to the amount of loading. At the same time, at each point of the volume, the charge will have the same technological properties, which will cause the same parameters of the plastic layer as it advances in a well-averaged loading and the same properties of the coke volume of the piece. Adjusting the optimal particle size distribution of the charge is the most effective method of improving the quality of blast furnace coke, which is very important in the future due to the decrease in the sintering ability of the coal charge, as the share of Zh and K coals in the charge decreases. Regulation of the optimal granulometric composition of the charge is the most effective method of improving the quality of blast furnace coke, this is very important in the future in connection with the decrease in the sintering ability of the coal charge, as the proportion of Z and K coal in the charge decreases. The laboratory study analyzed the effect on the particle size distribution of the coal charge of the design of crushing equipment: models of roller, jaw, impact, hammer, and disintegrator crushers. To obtain a charge with an optimal particle size distribution, it is rational to use selective crushing of only a large part of the charge. This can be achieved by using rotary crushers, in which small fractions pass through the crushing chamber in transit, i.e. without interaction with the working body. To optimize the crushing process, we propose to increase the number of revolutions in a rotary crusher by 20 %, since the result of crushing in a rotary crusher is closest to the optimal one. We also propose an adjusted crushing criterion, which takes into account that the optimal content of the (-0.5) mm fraction.

It has been shown that there is a high incidence of injuries to mountain workers due to falling pieces of rock in underground mining pits. From the published materials it is clear that in deep ore mines, on average, 40% of all injuries on mining robots are mainly caused by falls from invisible pins and scrapes in the walls and walls of mining machines. Increasing productivity works under the influence of a stronger environment. The main way to identify potential stains is by tapping the surface of the oil mass, as the frill is called, which is associated with a forceful infusion onto the mass and is potentially unsafe. The design is based on a device for non-force acoustic ultrasonic scanning of the roofing and walls of the roofing wall with the method of detecting the presence of pins and shading. Active control of the massif is based on the specific nature of the division of mechanical-acoustic springs in the Georgian breed. An analysis of the reaction of the Girsky breed to an exciting acoustic pulse in the ultrasonic spectrum was carried out. It was revealed that the reaction of the breed lies at the stage of mechanical connection of the controlled plot with the entire Girsky massif, therefore, by the magnitude of the amplitude and extinction of the acoustic sound, one can judge the stage of autonomy of the plot and possibly There is a deboning. The detection of cracks, which causes increased reverberation of the signal due to vibrations between the sections in the cracks, which leads to increased amplitude and frequency of strong resonant vibrations. The device was disassembled, prepared and tested until the last moment and fitted with the sensor to accommodate two independent sensors, one of which works on vibration, and the other on reception. To ensure high sensitivity, frequency and small dimensions, a resonant converter based on the active element of the PZT material was used - 23 with barium titanate with added lead and zirconium titanate. The vicinity of the dual-element sensor allows you to insert the middle element of the vibrating element into the receiving element. The elements are acoustically isolated from one type to another. The acoustic scanning frequency is assumed to be 20 kHz, the duration of the scanning pulse is 0.3 ms. Is shown block diagram and a photo of the visible sensor.

Published: April 2024

This article deals with the research related to the reengineering of stackers, which were developed and manufactured at the end of the twentieth century and are still in operation at a number of enterprises of the mining and metallurgical complex of Ukraine. For this study, we chose a modernized stacker type U1 SN-1200, which is still in operation at the iron ore pellets storage area of the pelletizing plant of the Central Mining and Processing Plant of Kryvyi Rih. Its modernization involved the removal of a very bulky, heavy outdated aspiration system, which could significantly affect the rollover stability of its platform and lead to the failure of both its individual components and the stacker as a whole. Therefore, the aim of the research was to conduct studies related to determination of the stacker's margin of safety against overturning depending on its design features that have emerged over the course of its operation and performance for materials whose bulk density does not exceed 1,9 t/m3. To achieve this goal, we used calculation and analytical methods in the MathCAD environment. The main source materials for calculations and research were archival drawings of the stacker and its technical passport. The research found that even with its nine-ton aspiration unit removed, the unit, which is significantly offset from the center of gravity of the entire structure, the safety margin of the stacker to overturning, depending on the capacity, is in the range of 1,6-1,9. Installation of an additional 9 t load instead of the aspiration unit, increases the safety margin of the stacker to 2,2, and without it to 1,8 at maximum stacker productivity of 1200 t/h.

Edo Tensei Pembelajaran Sejarah
Authors: Santosa Nyong Eka Teguh Iman
Published: April 2024

This paper highlights the urgency of prophetic epistemology in learning history. Without neglecting the contribution of learning styles that emphasize the notion of history as a scientific effort to find truthful facts in the past, prophetic epistemology can strengthen its relevance as something that is permanent and will always be needed in education. Through a reflective approach to the Naruto anime story that introduced the kinjutsu Edo Tensei, the main issues are analyzed within some philosophical frameworks on history. Conceptual elaboration is also carried out through contemplation of several Qur'anic verses related to history, namely surah al-Hashr verse 18, Yusuf 111, and al-Rum 9. It is concluded that learning history should be able to activate students' prophetic awareness that history is a critical reading of past events as well as a transformative engagement of the present with ethical commitment.

Published: April 2024

The development of education in Indonesia in the 4.0 era is quite significant in terms of learning. The emergence of artificial intelligence (AI) technology provides opportunities and challenges for implementing history learning at the elementary to high school levels. This research aims to answer the problem of why AI technology is important in learning history and what its benefits are. The method used in research is the historical research method. The results of this research show that the development of history learning based on artificial intelligence (AI) in the digital era 4.0 continues to develop, making history learning a challenge for educators because it not only requires an understanding of historical facts but also interpretation and analysis as well as the application of learning strategies using AI. The benefits of using AI in history learning are increasing learning efficiency by reducing the time needed to search for information, increasing student interaction with learning material through the use of technology that attracts attention, and increasing students' understanding of the historical context through data visualization and analysis. The challenge in using AI is the teacher's lack of ability to follow developments in AI-based learning, and the use of AI technology in history learning is the lack of relevant and quality data.

Published: April 2024

In randomized controlled trials, individual subjects experiencing recurrent events may display heterogeneous treatment effects. That is, certain subjects might experience beneficial effects, while others might observe negligible improvements or even encounter detrimental effects. To identify subgroups with heterogeneous treatment effects, an interaction survival tree approach is developed in this paper. The Classification and Regression Tree (CART) methodology (Breiman et al., 1984) is inherited to recursively partition the data into subsets that show the greatest interaction with the treatment. The heterogeneity of treatment effects is assessed through Cox’s proportional hazards model, with a frailty term to account for the correlation among recurrent events on each subject. A simulation study is conducted for evaluating the performance of the proposed method. Additionally, the method is applied to identify subgroups from a randomized, double-blind, placebo-controlled study for chronic granulomatous disease.

Presently, impurity-compensated silicon (Si) has no clear potential applications due to high resistance and few carriers. Thus, it has received little attention from researchers. In this study, we find that impurity compensation can make localized state energy levels form in Si bandgap, which can improve the light absorption of Si in the near infrared region. In this work, in order to comprehensively and deeply understand the photoelectric properties of impurity-compensated Si, the localized state energy levels composed of P+/B– ions are constructed in Si bandgap through the co-doping of phosphorus (P) and boron (B), thereby forming impurity-compensated Si. The first-principles based on a density functional theory framework is used to study the photoelectric properties of the impurity-compensated Si (n/p-Sic) such as the density of states (DOS), dielectric function and refractive index. The DOS study reveals the following results: after the n- and p-Si with the same concentration of P and B (12.5%) are fully compensated for by impurities, the Fermi energy levels of their compensated counterparts are at the valley bottom formed by the two adjacent DOS peaks, and the DOS is not zero at the valley bottom. In the study of dielectric function and refractive index, it is found that when the doping ratio is CB/CP0 = 0.25, n-Sic has the largest dielectric function and refractive index in the low energy region. In addition, comparing intrinsic Si with its doped counterparts in the real part (Re) of their dielectric constant, the following regularity is found: in the high energy region of E > 4 eV, the Re values of the intrinsic Si, n/p-Si and p-Sic are negative. In the low energy region of 0.64 eV< E < 1.50 eV, the Re value of n-Sic is negative for the doping ratio of CB/CP0 = 0.25. The above comparison indicates that the n-Sic with CB/CP0 = 0.25 can achieve good metallicity in the low energy region, indicating that the electrons in valence band are easily excited by low-energy long-wavelength light. Theoretical studies show that the good photoelectric properties of n-Sic with CB/CP0 = 0.25 may be related to Si dangling bonds and localized state energy levels in Si bandgap. The Si dangling bonds are caused by the impurity compensation of B dopant for n-Si, leading part of Si-Si bonds to change into Si-B bonds. This study provides theoretical guidance for the application of impurity-compensated Si in the field of photodetectors such as CMOS image sensors and infrared photodetectors.

Los ambientes acuáticos urbanos están altamente afectados por la contaminación de origen puntual o difuso. Este trabajo tuvo como objetivo determinar el impacto antrópico en un río urbano de la provincia de San Luis, Argentina, mediante la estimación de su calidad fisicoquímica, biológica e hidromorfológica. El área de estudio se centró en un río con impacto antropogénico, donde se tomaron muestras de agua y de macroinvertebrados bentónicos, durante dos años en períodos de aguas bajas y altas, en cinco sitios (n = 40). Se adaptó un índice de calidad de ribera QBRs para las ciudades de Juana Koslay y San Luis, Argentina. Los parámetros físico-químicos analizados fueron pH, temperatura, turbidez, conductividad, sólidos totales disueltos, oxígeno disuelto, demanda bioquímica de oxígeno, materia orgánica y concentración de nitrato y fósforo. Se aplicó un índice físico-químico simplificado de calidad de agua (ISQA). Los macroinvertebrados se muestrearon con red D, se identificaron en laboratorio, y se aplicaron el Índice Biótico para las Sierras de San Luis (IBSSL), y el índice Biological Monitoring Working Party (BMWP). Se estimó riqueza y abundancia de taxones, y se aplicó el índice integral ESCOTRIMED. El Índice ISQA y los índices bióticos mostraron un gradiente desde ambientes contaminados, a ambientes extremadamente contaminados. La riqueza y la abundancia de macroinvertebrados disminuyeron río abajo, siguiendo un gradiente de contaminación creciente. La integración de los parámetros fisicoquímicos, biológicos y de ribera permitió determinar el impacto producto de la urbanización creciente del río, mostrando desde ambientes con fuertes signos de alteración a zonas con deterioro incipiente.

One Health approach emerges as an innovative perspective to understand the health-disease process of acute Chagas disease (ACD). This study aimed to identify scientific evidence on the health-disease process of ACD through one health approach. This integrative literature review study had as guiding question: what is the current scientific evidence on the health-disease process of ACD according to One Health approach? A greater number of studies can be seen from 2021. The following categories were defined from the 13 studies found: One Health approach to Chagas disease; Spatial epidemiology of Chagas disease; Control and transmission factors of Chagas disease; Health indicators in Chagas disease; and Educational technology in Chagas disease. The results of this literature review, while showing greater proportions of studies involving ACD control and transmission, also demonstrate fields of study that are still little explored by national and international scientific literature, such as in the field of technologies for ACD, reflecting a large gap to be filled with future research on ACD. This study contributed to expanding the debate on the importance of an integrative approach in health research and encouraging the search for more comprehensive solutions for ACD.

This research studied cross country trade and economic growth with the analysis of its impact on Nigeria’s economic growth. It covered time series data from 1992 to 2020 with gross domestic product, exports, imports, foreign direct investment and openness of trade as variables included in the model. The ARDL model was used for data analysis and the outcome showed positive and significant relationships between exports, imports and openness of trade and economic growth while the relationship between foreign direct investment and economic growth was negative but, significant. The gap created in this study lies in the year of coverage and the variables of the model which actively are involved in international trade compared to variables of reviewed studies.  The study concluded that variables with positive relationships with economic growth are the ones that contribute or cause economic growth to increase as they increase while foreign direct investment that has negative relationship with economic growth only reduces economic growth as it increases in value. It recommended that priority should be given to local production of export goods and the reduction of import goods with the exception of technology imports.
