Published: February 2024

Every human being has a different culture and self-identity. These differences can be adjusted through intercultural communication activities. This study discusses adjusting the language code in intercultural communication for students from Nusa Tenggara Timur (NTT) towards Javanese Culture within the Stikosa-AWS Campus which aims to find out how the process of adjusting the language code in intercultural communication for students from NTT who interact with Javanese people. The method used in this study is a qualitative descriptive method in which to analyze data on cases that occur objects. The research subjects were five students from NTT, one of whom was born in Surabaya and lives near the Stikosa-AWS Campus. The results of this study indicate that verbal and nonverbal are used when adapting the language code between students from NTT to Javanese culture. A dialect is a verbal form that NTT students can adapt due to daily interactions. There are only slight differences in nonverbal forms such as gestures, expressions, accents, intonation, and tempo of NTT students who live in the Javanese ethnic area, namely, only body movements. The processes NTT students can go through with Javanese culture are assimilation and integration. NTT students and the surrounding Javanese community both assimilate without prejudice to each other to gain comfort and peace. The integration process is carried out by maintaining regional language codes but still interacting with each other. The

attitude that must be possessed by NTT students and the Javanese community is to emphasize mutual tolerance.

The Influence of Hydrogeological Conditions on Salt Quality Standards In Ambal District, Kebumen Regency, Central Java
Authors: Radityo Daniel , Pratomo Septyo Uji
Published: February 2024

Salt (NaCl), also known as halite, has a vital role as an essential ingredient in human life and industry. Kebumen Regency in Central Java, especially along the south coast in Ambal District, is one of the area in Indonesia that produces salt, originating from elongated dome-shaped salt ponds, which are the primary source of salt production in the region. Salt quality standards are regulated by SNI 3556:2016, which provides limits for metal contamination such as cadmium (Cd) 0.5 mg/kg, lead (Pb) 10 mg/kg, mercury (Hg) 0.1 mg/kg, and arsenic (As) 0.1 mg/kg. The conditions of seawater and groundwater used in the salt production process have a significant impact on the quality of the salt produced, which can be determined from hydrogeological studies. The results of measuring residents' wells at 43 points show that the depth of the groundwater level ranges from 4.4 to 14.75 meter below sea level. The results of salt analysis from 2 different salt ponds showed Cd levels ranging between 0.0949—0.1001 mg/kg, Pb between 0.5163—0,755 mg/kg, Hg between 0.01198—0.06203 mg/kg, and negative As levels; with water content ranging from 14.43-14.92% w/w and NaCl content between 72.3-85.8%. The analysis of well water and seawater from 3 samples showed Cd 0.0009 mg/kg, Pb 0.0011-0.0098 mg/kg, Hg 0.0001 mg/kg, and As 0.001 mg/kg. The results of groundwater level mapping show that hydrogeological conditions influence the quality standards for salt on the southern coast of Kebumen, especially by the significant grain size factor that carries groundwater and the elements dissolved in it. Meanwhile, salt produced from 2 salt ponds in Ambal District did not meets quality standards based on SNI 3556:2016.

Pseudocysts of the jaws include two very significant lesions – Solitary bone cyst (SBC) and Aneurysmal bone cyst (ABC). Both these cysts have very similar clinical and radiological findings. Histopathology aids in differentiating the two pathologies, with MRI findings offering confirmatory diagnosis of ABC. Differentiating between the two cysts and establishing a definitive diagnosis cannot be over emphasised as prognosis depends on the correct treatment modality after the diagnosis. A lot of updates with regards to the treatment of these cysts in long bones is available, with the same lacking in the cysts of the jaws. This probably could be due to the relative rarity of these cysts in the jaws. This article aims to address the various aspects of these two enigmatic pseudocysts of the jaws.

The implementation of the curriculum and assessment policy statement
Authors: Mabunda Pinkie
Published: February 2024

Worldwide, national educational authorities set curricular guidelines for schools to ensure implementation. Despite these measures, the translation of policies into school or classroom activities is rarely a smooth or complete process. South Africa has made significant and much-needed positive curriculum changes. However, effective curriculum implementation requires a sound understanding of the curriculum policy, adequate and varied resources and greater attention to contextual factors. Using the interpretivist paradigm and qualitative research design, the study explored the perspectives and experiences of school managers regarding the challenges and problems of implementing the Curriculum and Assessment Policy Statements in the Intermediate Phase within the South African curriculum reform context. For the first research question, the thematically analysed data generated the findings which highlight a generally good understanding and positive outlook of the revised curriculum policy by the participants. In contrast, the findings for the second research question confirmed that inadequate resources such as a shortage of teachers and textbooks, overcrowded classrooms and other learning support materials impact teaching and learning and the process of curriculum implementation negatively. The study contributes to the important topic of curriculum reforms and curriculum implementation challenges and problems. The study recommends, among others, strategies needed for monitoring the implementation of the CAPS, placing individual school managers as change agents and adopting the three constructs of the theory of curriculum implementation for strengthening implementation.
Regular schools as a straitjacket for zone of proximal development
Authors: De Souza Ben
Published: February 2024

Malawi has a twin-track system of primary and secondary education. In this system, some learners with special educational needs are enrolled in regular schools while others are still in special schools. Research has shown that regular schools receive learners with special educational needs into the system but with the possibility of enabling and constraining their developmental and learning abilities. Put metaphorically, when learners with special educational needs are placed in regular schools, they are dressed in straitjackets that may enable or constrain their development and learning. A straitjacket refers to the freedom and limitations that regular schools give learners with special educational needs. When prisoners and people with mental health conditions are dressed in straitjackets, the foremost reason is to ensure that they can be easily restrained once they turn violent. This situation can be understood through a theoretical frame of what Lev Vygotsky termed the zone of actual development versus the zone of proximal development which was employed in this study. The study conducted in-depth interviews with ten regular teachers from five regular secondary schools in the South West Education Division in Malawi. The results from the interviews show that inclusive education is failing at the point of implementation due to: (1) a lack of capacity development for regular teachers, (2) limited support for learners with special educational needs, (3) inadequate specialist teachers, and (4) lack of parental and community involvement. These challenges originate from an entrenched view on special education that makes the transition to inclusive education cumbersome. I, therefore, argue that special education should be used as a stepping-stone into inclusivity to expand learning rather than as a discriminating tool against learners with special educational needs. The study proposes a third space schooling model in which special education facilitates inclusivity towards the zone of proximal development. The study concludes that the third space model has the potential to help Malawi and other countries to move towards meaningful, inclusive education.
The economic rationale for the provision of technical/vocational education (TVE) in colonial Ghana: Implications for practice
Authors: Oti-Agyen Philip
Published: February 2024

The paper examines the economic rationale for the provision of technical/ vocational education (TVE) in colonial Ghana.  It further highlights some key lessons drawn from the study, particularly, in term of the Ghanaian contemporary search for a more pragmatic policy formulation for TVE. Data were retrieved from primary sources in the form of archival materials and some secondary sources as well some interview sessions with two personalities who were actively involved in the provision of TVE during the period.   Chronological and thematic analysis of the data were utilized.  The study revealed that the missionary bodies and the colonial administration vigorously promoted TVE largely because of economic reasons.   It further argues that this level of vigor could not unfortunately keep pace with the developmental needs of the country due mainly to overriding interest in literary/grammar education, lack of entrepreneurial training for graduates of the TVE institutions and virtual non-existence of local industries to absorb these graduates.
Bridging gender disparities in the teaching profession in tertiary institutions for globalisation
Authors: Etejere Patricia A. O. , Oluwalola Felicia K. , Awodiji Omotayo Adewale , Sagaya Amudalatu A.
Published: February 2024

Globally, female teachers have established careers in teaching. In Nigeria, there are more females in the teaching profession at lower levels of education than at tertiary institutions. This study examined the gender distribution rate of teachers in secondary and tertiary institutions and the factors that caused differences in gender balance at tertiary institutions using mixed method research. A proforma form was used to collect quantitative secondary data, while the interview guide was used to collect qualitative data. Descriptive statistics of frequency and percentage were used to analyse the quantitative data collected to establish the rate of male and female teachers. The qualitative data were analysed thematically with the aid of Atlas ti. The results showed that the rate of female teachers outweighed their male counterparts by 4.35% at secondary schools, while male lecturers outnumbered female lecturers by 54.67% at the tertiary level. Lack of ambition to aspire higher, as well as societal perspective and marriage, among others, were factors responsible for the low rate of female lecturers in tertiary institutions. In order to address the gender gapidentified at tertiary institutions for globalisation, educational policy makers were advised to ensure that tertiary institutions increase the percentage of women in their academic recruitment.
Ideology, statecraft and the ‘double shuffle’ of Conservative planning reform in England
Authors: Shepherd Edward , Inch Andy , Sturzaker John , Marshall Tim
Published: February 2024

This article explores the political implications of conflicts over new housebuilding for Conservative-led governments in England since 2010. Revisiting debates about the tensions between neoliberal and more collectivist traditions within the political ideology of the Conservative Party, we argue that rather than blocking change this internal conflict should be seen as a dynamic part of the politics of planning. This leads us to propose that Conservative planning reforms have been characterised by a distinctive ‘double shuffle’ through which the party has sought to progress neoliberalising reforms whilst managing these tensions and seeking to maintain their hold on power through statecraft.

PROBABILISTIC MANAGEMENT OF PAVEMENT DEFECTS WITH IMAGE PROCESSING TECHNIQUES
Authors: Obunguta Felix , Matsushima Kakuya , Susaki Junichi
Published: February 2024

Pavement management has traditionally relied on human-based decisions. In many countries, however, the pavement stock has recently increased, while the number of management experts has declined, posing the challenge of how to efficiently manage the larger stock with fewer resources. Compared to efficient computer-based techniques, human-based methods are more prone to errors that compromise analysis and decisions. This research built a robust probabilistic pavement management model with a safety metric output using inputs from image processing tested against the judgment of experts. The developed model optimized road pavement safety. The study explored image processing techniques considering the trade-off between processing cost and output accuracy, with annotation precision and intersection over union (IoU) set objectively. The empirical applicability of the model is shown for selected roads in Japan.

We present new catalogs of likely globular clusters (GCs) in 17 nearby spiral galaxies studied as part of the PHANGS Hubble Space Telescope (HST) Treasury Survey. The galaxies were imaged in five broadband filters from the near-ultraviolet through the I band. PHANGS-HST has produced catalogs of stellar clusters of all ages by selecting extended sources (from multiple concentration index measurements) followed by morphological classification (centrally concentrated and symmetric or asymmetric, multiple peaks, and contaminants) by visually examining the V-band images and separately by a machine-learning algorithm which classified larger samples to reach fainter limits. From both cluster catalogs, we select an initial list of candidate GCs which have B − V ≥ 0.5 and V − I ≥ 0.73 mag, then remove likely contaminants (including reddened young clusters, background galaxies misclassified by the neural network, and chance superpositions/blends of stars) after a careful visual inspection. We find that ≈86% of the color-selected candidates classified as spherically symmetric and 68% of those classified as centrally concentrated but asymmetric are likely to be GCs. The luminosity functions of the GC candidates in two of our 17 galaxies, NGC 628 and NGC 3627, are atypical, and continue to rise at least 1 mag fainter than the expected turnover near M

V
∼ −7.4. These faint candidate GCs have more extended spatial distributions than their bright counterparts, and may reside in the disk rather than the bulge/halo, similar to faint GCs previously discovered in M101. These faint clusters may be somewhat younger since the age–metallicity degeneracy makes it difficult to determine precise cluster ages from integrated colors once they reach ≈1 Gyr.
Shedding Light on the Ejection History of Molecular Outflows: Multiple Velocity Modes and Precession
Authors: Lora V. , Nony T. , Esquivel A. , Galván-Madrid R.
Published: February 2024

Variable accretion has been well studied in the evolved stages of low-mass star formation. However, the accretion history in the initial phases of star formation is still a seldom studied topic. The outflows and jets emerging from protostellar objects could shed some light on their accretion history. We consider the recently studied case of W43-MM1, a protocluster containing 46 outflows driven by 27 protostellar cores. The outflow kinematics of the individual cores and associated knots in W43-MM1 indicate episodic protostellar ejection. We take the observed parameters of an individual core system (core #8) and perform 3D hydrodynamic simulations of such a system, including episodic changes in the velocity of the outflow. The simulations consist of a collimated jet emerging from a core, taking into account one- and two-velocity modes in the variation of the ejection velocity of the jet. In addition, we investigated the effect of including the precession of the jet in the one- and two-velocity-mode models. From the simulations, we constructed position–velocity diagrams and compared them with the observations. We find that including a second mode in the ejection velocity, as well as the precession, are required to explain the positions of the outflow knots and other position–velocity features observed in core #8 in W43-MM1.
Most-likely DCF Estimates of Magnetic Field Strength
Authors: Myers Philip C. , Stephens Ian W. , Coudé Simon
Published: February 2024

The Davis–Chandrasekhar–Fermi (DCF) method is widely used to evaluate magnetic fields in star-forming regions. Yet it remains unclear how well DCF equations estimate the mean plane-of-the-sky field strength in a map region. To address this question, five DCF equations are applied to an idealized cloud map. Its polarization angles have a normal distribution with dispersion σ

θ
, and its density and velocity dispersion have negligible variation. Each DCF equation specifies a global field strength B
DCF and a distribution of local DCF estimates. The “most-likely” DCF field strength B

Life in a Random Universe: Sciama's Argument Reconsidered
Authors: Wang Zhi-Wei , Braunstein Samuel L.
Published: February 2024

Random sampling in high dimensions has successfully been applied to phenomena as diverse as nuclear resonances, neural networks, and black hole evaporation. Here we revisit an elegant argument by the British physicist Dennis Sciama, who demonstrated that were our Universe random, it would almost certainly have a negligible chance for life. Under plausible assumptions, we show that a random universe can masquerade as “intelligently designed,” with the fundamental constants instead appearing to be fined tuned to achieve the highest probability for life to occur. For our Universe, this mechanism may only require there to be around a dozen currently unknown fundamental constants. We speculate on broader applications for the mechanism we uncover.

Published: February 2024

We present evidence of variable 1.3 mm emission from the 1 to 3 Myr, spectral-type G2–G5 class III young stellar object (YSO), HD 283572. HD 283572 was observed on eight dates with the Submillimeter Array between 2021 December and 2023 May, with a total on-source time of 10.2 hr, probing a range of timescales down to 5.2 s. Averaging all data obtained on 2022 January 17 shows a 4.4 mJy (8.8σ) point source detection with a negative spectral index (α = −2.7 ± 1.2), with peak emission rising to 13.8 mJy in one 3 minute span, and 25 mJy in one 29.7 s integration (L

ν
= 4.7 × 1017 erg s−1 Hz−1). Combining our data for the other seven dates shows no detection, with an rms noise of 0.24 mJy beam−1. The stochastic millimeter enhancements on time frames of seconds–minutes–hours with negative spectral indices are most plausibly explained by synchrotron or gyrosynchrotron radiation from stellar activity. HD 283572's 1.3 mm lightcurve has similarities with variable binaries, suggesting HD 283572's activity may have been triggered by interactions with an as-yet undetected companion. We additionally identify variability of HD 283572 at 10 cm, from VLASS data. This study highlights the challenges of interpreting faint millimeter emission from evolved YSOs that may host tenuous disks, and suggests that a more detailed temporal analysis of spatially unresolved data is generally warranted. The variability of class III stars may open up new ground for understanding the physics of flares in the context of terrestrial planet formation.
Riparian invader: A secondary metabolite of Impatiens glandulifera impairs the development of the freshwater invertebrate key species Chironomus riparius
Authors: Hüftlein Frederic , Diller Jens G. P. , Feldhaar Heike , Laforsch Christian
Published: February 2024

Invasive species represent a significant threat to native biodiversity. The Himalayan Balsam Impatiens glandulifera is an annual plant, which is invasive in Europe and often inhabits the riparian zone. It produces several secondary metabolites causing for example growth inhibition of terrestrial plants and invertebrates. One of these metabolites is the quinone 2-methoxy-1,4- naphthoquinone (2-MNQ). The compound gets washed out from the above-ground parts of the plant during precipitation, and may then leach into nearby water bodies. Despite some evidence for the allelopathic effect of plant secondary metabolites on terrestrial invertebrates, little is known about how 2-MNQ affects the survival or development of aquatic dipteran larvae, despite the importance of this functional group in European freshwaters. Here we investigated the effects of 2-MNQ on larvae of the river keystone species Chironomus riparius in acute and chronic scenarios. The toxicity of 2-MNQ towards the first and the fourth larval stage was determined in a 48 hours acute exposure assay. We show that 2-MNQ has a negative impact on development, growth, and survival of Chironomus riparius The LC50 of 2-MNQ was 3.19 mg/l for the first instar and 2.09 mg/l for the fourth instar.

A ten-day chronic exposure experiment, where the water was spiked with 2-MNQ, revealed that 2-MNQ had a significantly negative impact on larval body size, head capsule size, body weight, development and survival. These results demonstrate the negative impact of the secondary metabolite 2-MNQ from the terrestrial plant I. glandulifera on a crucial macroinvertebrate inhabiting the adjacent stream ecosystem in riverine ecosystems. This may lead to a decline in population size, resulting in cascading effects on the food web.
Toward A Fuller Definition for the Science of Nursing Education Through Hermeneutical Analysis
Authors: Dzurec Laura C.
Published: February 2024

Background:

Authors writing about the science of nursing education have tended to focus extensionally, describing and analyzing the significance and benefits of nurse educators' unique, individual teaching endeavors, rather than clarifying their perceptions of the intensional core essence of the science itself. As a result, communal thinking about the science of nursing education and its implications for student learning are constrained. Methods: Hermeneutical analysis of published reports and narratives supported identification of a provisional, intensionally oriented definition of the science guiding nurse educators' disciplinary practice.

Results:

The emerging definition was “study of nurse educators' mindful implementation of effective and meaningful learning opportunities to enculturate graduates for practice excellence guided by nursing's disciplinary knowledge.”

Conclusion:

A working, intensional definition of the science of nursing education emphasizes qualities central to nurse educators' practice, ultimately contributing to preparing graduates for professional nursing practice.

Characterizing the Journey of Geographic Atrophy Patients in Routine Ophthalmic Practice
Authors: Gupta Urvi , Maatouk Christopher M. , Markle Jonathan C. , Talcott Katherine E. , Singh Rishi P. , Rachitskaya Aleksandra V.
Published: February 2024

Background and Objective:

Geographic atrophy (GA) is a form of late-stage age-related macular degeneration (AMD). This study aims to characterize the journey of patients with GA in real-world ophthalmology practice.

Patients and Methods:

This is a retrospective cohort study of 100 patients with GA and 100 with intermediate AMD (iAMD).

Results:

Approximately one-third of GA patients' eyes had GA at the time of their initial AMD diagnosis, and nearly half of the iAMD patients' eyes had iAMD at that time. When holding confounders constant, GA patients experienced significantly worse visual acuity outcomes, and a significantly higher proportion required referrals for low vision evaluation, needed assistance for activities of daily living, failed to meet driving standards, and met criteria for legal blindness when compared to iAMD controls.

Conclusions:

Many patients have already progressed to GA by the time they receive an AMD diagnosis, emphasizing the importance of providing early detection and intervention, especially considering novel treatment options.

Published: February 2024

Background and Objective:

We sought to establish normative quantitative contrast sensitivity function (qCSF) values in healthy adult eyes and investigate the effect of age on qCSF.

Patients and Methods:

Healthy eyes underwent qCSF testing (adaptive sensory technology) and Snellen's visual acuity (VA). Descriptive statistics and mixed-effects multivariable linear regressions were evaluated.

Results:

A total of 334 eyes (290 patients) with median age 61 years (range 21 to 88) had qCSF values as follows: area under the log contrast sensitivity function curve: 1.18; contrast acuity: 1.32; contrast sensitivity (CS) at 1 cycle per degree (cpd): 1.32; CS at 1.5 cpd: 1.37; CS at 3 cpd: 1.38; CS at 6 cpd: 1.20; CS at 12 cpd: 0.69; CS at 18 cpd: 0.22. Linear reductions in qCSF values per decade of age ranged from −0.02 to −0.07 vs 0.01 for visual acuity (VA). Age had a greater effect on the majority of qCSF values than VA (beta standardized regression coefficient ranged from −0.309 to −0.141 for qCSF values vs 0.177 for VA).

Conclusions:

We herein establish a normative database for qCSF and quantify the effect of age on qCSF values, adding evidence towards the validation of qCSF as a clinical endpoint.

Pointwise error estimate of conservative difference scheme for supergeneralized viscous Burgers' equation
Authors: Shi Yang , Yang Xuehua
Published: February 2024

This work focuses on exploring pointwise error estimate of three-level conservative difference scheme for supergeneralized viscous Burgers' equation. The cut-off function method plays an important role in constructing difference scheme and presenting numerical analysis. We study the conservative invariant of proposed method, which is energy-preserving for all positive integers $ p $ and $ q $. Meanwhile, one could apply the discrete energy argument to the rigorous proof that the three-level scheme has unique solution combining the mathematical induction. In addition, we prove the $ L_2 $-norm and $ L_{\infty} $-norm convergence of proposed scheme in pointwise sense with separate and different ways, which is different from previous work in [1]. Numerical results verify the theoretical conclusions.
Unsupervised domain adaptation with deep network based on discriminative class-wise MMD
Authors: Lin Hsiau-Wen , Tsai Yihjia , Lin Hwei Jen , Yu Chen-Hsiang , Liu Meng-Hsing
Published: February 2024

General learning algorithms trained on a specific dataset often have difficulty generalizing effectively across different domains. In traditional pattern recognition, a classifier is typically trained on one dataset and then tested on another, assuming both datasets follow the same distribution. This assumption poses difficulty for the solution to be applied in real-world scenarios. The challenge of making a robust generalization from data originated from diverse sources is called the domain adaptation problem. Many studies have suggested solutions for mapping samples from two domains into a shared feature space and aligning their distributions. To achieve distribution alignment, minimizing the maximum mean discrepancy (MMD) between the feature distributions of the two domains has been proven effective. However, this alignment of features between two domains ignores the essential class-wise alignment, which is crucial for adaptation. To address the issue, this study introduced a discriminative, class-wise deep kernel-based MMD technique for unsupervised domain adaptation. Experimental findings demonstrated that the proposed approach not only aligns the data distribution of each class in both source and target domains, but it also enhances the adaptation outcomes.
The Health Narratives Research Group (HeNReG): A self-direction process offered to help decrease burnout in public health nurse practitioners
Authors: Nash Carol
Published: February 2024

Founded in accordance with 19th century sex roles and public health concerns, nursing evolved as other-directed, dependent on physician-focused diagnosis, prescription decisions, and public health advancements. The result of this other direction is that public health nurse practitioners have endured significant workplace stress resulting in burnout, especially during COVID-19. To help decrease their burnout, nurses require development of self-direction. The Health Narratives Research Group (HeNReG) has the potential to reduce burnout in nurse practitioners by encouraging the development of self-direction. The HeNReG process is presented through historically analyzed documents regarding reducing burnout in health researchers by developing self-direction including: (1) three years of archived year-end feedback results provided by participants, (2) archived participant responses to specific HeNReG-related writing prompts, and (3) a comparison of HeNReG results with the outcomes of resilience programs. The conclusion—the HeNReG offers an effective option for reducing burnout in health researchers that has the potential to decrease nurse practitioner burnout in a way that resilience programs do not. Tailoring the HeNReG process to public health nurses is discussed, inviting future research for reducing burnout in public health nurses.

Ivan da Silva Bruhns : le Brésil en dialogues
Authors: Vaudry Élodie
Published: February 2024

Artiste protéiforme, le brésilien Ivan da Silva Bruhns, né en France en 1881, se fait connaître par la réalisation de tapis monumentaux pour les gouvernements français et étrangers et de riches mécènes, des années 1920 jusqu’à sa mort en 1980. Il puise son inspiration dans l’histoire du textile, plus particulièrement dans les savoir-faire berbères et mexicains. Parallèlement, il pratique la peinture toute sa vie, des huiles sur bois sur des formats moyens. Les formes anthropomorphes, zoomorphes, les portraits masqués et autres figures énigmatiques et géométriques parcourent son œuvre teintée d’appropriations africaines, précolombiennes et imaginaires. Son travail témoigne d’une réflexion sur le cubisme, l’abstraction et la couleur. Dialogues entre les arts, entre les formes et les aplats chromatiques, entre les cultures, l’oeuvre peinte d’Ivan da Silva Bruhns est profondément discursive et mérite d’être étudiée.
Lecciones de la historia africana
Authors: Fauvelle François-Xavier
Published: February 2024

Si nunca está de más señalar que las sociedades africanas están constituidas por el mismo tejido histórico que todas las demás sociedades, el pasado de África ha permanecido desconocido durante mucho tiempo. Ser historiador o arqueólogo especializado en África consiste tanto en desbrozar el pasado como captar su diversidad: la riqueza de la literatura oral y de la documentación escrita, la pluralidad de lenguas y religiones, la inventiva técnica y social, la cohabitación de formas políticas. Atento a las múltiples trayectorias históricas presentes, François-Xavier Fauvelle nos invita a escuchar lo que la historia de África tiene que enseñarnos.
