Zero-Sum Squares in $\{-1, 1\}$-Matrices with Low Discrepancy
Authors: Johnston Tom
Published: May 2023

Given a matrix $M = (a_{i,j})$ a square is a $2 \times 2$ submatrix with entries $a_{i,j}$, $a_{i, j+s}$, $a_{i+s, j}$, $a_{i+s, j +s}$ for some $s \geq 0$, and a zero-sum square is a square where the entries sum to $0$. Recently, Arévalo, Montejano and Roldán-Pensado proved that all large $n \times n$ $\{-1,1\}$-matrices $M$ with discrepancy $|\sum a_{i,j}| \leq n$ contain a zero-sum square unless they are split. We improve this bound by showing that all large $n \times n$ $\{-1,1\}$-matrices $M$ with discrepancy at most $n^2/4$ are either split or contain a zero-sum square. Since zero-sum square free matrices with discrepancy at most $n^2/2$ are already known, this bound is asymptotically optimal.
Nuclear Deterrence and A Prospective Assessment of the Russian-Ukrainian War
Authors: Gülboy Burak Samih , Ercan Ali
Published: May 2023

Nuclear weapons, which people first became acquainted with in history with the attack on Hiroshima and Nagasaki by the United States of America towards the end of the Second World War, have been a deterrent tool, especially with this painful experience in which 220,000 civilians lost their lives, and have been used for this purpose when needed by those countries who possess them. Nuclear deterrence was most intensely used as a deterrent tool, especially during the Cold War and between the two great superpowers of the time, the Soviet Union and the United States. With the developments after Russia intervened in Ukraine in February 2022 and the wide support packages provided by Western countries to Ukraine, the President Vladimir Putin stated that the use of nuclear weapons is now among the options. In this study, firstly, concepts such as nuclear strategy, nuclear weapons, nuclear power, and nuclear deterrence will be discussed in the context of the conceptual framework; by following that, a prospective evaluation of the Russia-Ukraine war will be made in the context of nuclear deterrence.

Authors: Diananti Amanda Priska , Havriza Vitresia  , Getry Sukmawati
Published: May 2023

Background: Infectious corneal ulcer (CU) occurs due to an agent, which may be a bacterial, fungal, or viral microorganism. A detailed examination of the ulcer was needed to determine the severity grading of the ulcer. Based on the size, depth of ulcer, density of infiltrate, and scleral involvement, it's divided into mild, moderate, and severe grades and may be used to objectively monitor the progress of the ulcer and as a parameter for management. Medical management includes topical, systemic antibiotic, and periocular injection, while amniotic membrane transplantation (AMT), conjunctiva flap, fascia lata, and evisceration as surgical. This study aimed to assess the clinical grading associated with the management of CU in Dr. M. Djamil General Hospital, Padang, Indonesia.

Methods: Observational analytics based on the medical record of corneal ulcer patients in Dr. M. Djamil General Hospital, Padang, Indonesia, in 2016-2017. A total of 191 research subjects participated in this study. Data analysis was carried out using SPSS univariately.

Results: The fungal, bacterial, and viral CU was diagnosed clinically. The severity grading that we found is moderate (60,73%), mild (25,14%), and severe (14,13%). All of the cases used medical treatment. Surgical was performed in moderate (36,59%) and all severe cases. AMT was performed in severe cases with perforation ≤ 4 mm and perforation > 4 mm conjunctival flap (3.7%), fascia lata (3,7%), and evisceration (61,53%), preferably.

Conclusion: The clinical grading of corneal ulcers in our hospital is moderate, and it may be associated with our hospital as a referral hospital. Surgery was performed in all severe and moderate cases that don't respond well to medicine.
The Outcome of Concurrent Intracameral Fluconazole Injection with Amniotic Membrane Transplantation for Fungal Keratitis in Dr. M. Djamil General Hospital: A Case Series
Authors: Indratno Ferry , Havriza Vitresia
Published: May 2023

Background: Fungal keratitis is often difficult to eradicate and requires long treatment. Antifungal agents have lower efficacy because of low tissue penetration and the indolent nature of the infection. Fluconazole has effective ocular penetration ability, reaching aqueous concentration as same as plasm concentration. Multilayer amniotic membrane transplantation (MLAMT) has been shown to be a promising surgical procedure to reconstruct the ocular surface by supporting the epithelialization of the cornea and having protective antimicrobial properties. This study aims to report the outcome of concurrent intracameral fluconazole injection with amniotic membrane transplantation for fungal keratitis in Dr. M. Djamil General Hospital.

Case presentation: Four inpatients in the ophthalmology ward of Dr. M. Djamil General Hospital with moderate to severe fungal keratitis. All patients were first treated with medications. Because the patients did not show clinical improvement after getting maximum therapy, they underwent intracameral fluconazole injection concurrent with MLAMT. MLAMT was performed with multilayered amniotic membranes to fill and cover the defect. The bandage contact lens was placed to protect and keep the MLAMT in place and for patients’ comfort. Patients were then observed for signs of inflammatory reaction and epithelialization. All patients showed reduced inflammation and improved epithelization after surgery.

Conclusion: Concurrent intracameral fluconazole injection with MLAMT can be considered an alternative treatment for refractory fungal keratitis as it decreases the rate of inflammation and improves epithelization.

The government is committed to reducing greenhouse gas (GHG) emissions using new and renewable energy. Therefore, research related to the performance of mining sector companies is interesting because the performance of mining companies is one of the keys to the success of the government in implementing KEN. The method used in this research is descriptive quantitative through the application of panel data regression models to be able to analyze the characteristics of company CEOs in the mining sector. The result of the research is that the panel data model can provide an overview which is then analyzed for the relationship between CEO characteristics and company performance in the Indonesian mining sector. This study found that CEO's work experience and CEO's Strength and CEO's level of education did not significantly influence the performance of mining sector companies in Indonesia.
Assessing the Manner of Speech in Australian Courts: A Study of Chinese-English Professional Interpreters in Remote Settings
Authors: Yi Ran
Published: May 2023

Professional interpreters are bound by the code of conduct to interpret everything that has been said in courts. In particular, the manner that the propositional content is conveyed in the target language. Using the experiment method and questionnaire instruments, the mixed-methods research investigates the manner of speech and its interpretation in virtual courtroom discourse during remote interpreting. The working article presents the initial findings from two questionnaire instruments: one for demographics and general knowledge about speech style and discourse markers, the other for views and strategies related to the manner of speech in the interpreted utterances. Questionnaire data collected from fifty consented interpreters revealed the three main views on the rendition of the manner of speech: complete disregard as “irrelevant”, verbatim rendition without pragmatic considerations, and pragmatic equivalents for its possible impact on the court decision, ethical conduct, and professionalism. The findings intend to inform future pedagogical practice.
Indo-Israel Strategic Partnership in Indian Ocean and Outer Space: A Need for Regional Counter-Balancing Approach
Authors: Syed Fraz Hussain Naqvi
Published: May 2023

Indian space exploration has entered a new phase with the formation of the Indian Defence Space Agency (DSA) in 2018 and the procurement of anti-satellite capabilities in 2019. These two incentives prompted India to join the United States, Russia, and China in militarizing outer space. In a similar fashion, Israel conducted an ASAT test of the Arrow-3 missile interceptor aimed at the exo-atmosphere. While both India and Israel have described their outer space ambitions as removing debris from the lower orbit, the constant use of their military arsenals demonstrates their common goal of obtaining the upper hand over their respective rivals, Pakistan, China, and Iran. Prospects for their partnership in outer space are highly contingent on their cooperation in other defence domains, especially maritime security. For India, the Indian Ocean Region (IOR) is of utmost importance due to China's growing presence, whereas for Israel, the IOR represents a vital trade route that may be at risk due to the development of ports in Pakistan (Gwadar) and Iran (Chahbahar), through which these nations could acquire the means to expand their naval presence. Therefore, while space development complements geo-sensing, particularly in oceans, the interests of both India and Israel in space and IOR enhance the likelihood of their cooperation in these sectors. This paper evaluates how Pakistan, Iran, and China could form a trilateral alliance to counter the emerging US-supported Indo-Israeli nexus in IOR and outer space.

Digitale Bedarfsplanung mit BIM – das Raumbuch nach VDI 6070
Authors: Pauen Nicolas , Treeck Christoph van , Dux Eberhard
Published: May 2023

Building Information Modeling (BIM) bietet als kooperative Arbeitsmethode das Potenzial, basierend auf maschinenlesbaren Informationen in Form von BIM-Modellen, mit verschiedenen Akteuren in einem effizienten Prozess zusammenzuarbeiten. Die Modelle müssen jedoch nicht immer über eine zwei- oder dreidimensionale Geometrie verfügen. Das Digitale Raumbuch als praxisorientiertes Managementinstrument ermöglicht die Abbildung von alphanumerischen Informationen und Ausstattungsgegenständen an räumlichen sowie funktionalen und technischen Entitäten. Es kann daher in der Bedarfsplanung verwendet werden, um die Anforderungen des Bauherrn an das Bauwerk und die technische Gebäudeausrüstung, das heißt die Beschreibung des zu errichtenden „Produktes“, maschinenlesbar in einem frühen (BIM-)Modell zu dokumentieren. Damit schafft es die Grundlage für einen digitalen Informationsaustausch ab der Konzeptionsphase über den gesamten Lebenszyklus. Zudem kann es, wenn es parallel zur Planung fortgeschrieben wird, als Basis für Soll-Ist-Vergleiche der Qualitätssicherung oder als Grundlage für das CAFM dienen.

Review question / Objective: What is the effect of the use of technology for humanized nursing care in adults? Present a synthesis of knowledge about the elements that are part of humanized care and the use of technology. Condition being studied: Although technology can be a valuable tool to improve nursing care, it can also present some challenges for humanized care. Some of them may be, on the one hand, the lack of human contact, due to excessive use of technology, which may result in a decrease in personal interaction between the patient and the nurse, affecting the quality of care and patient satisfaction. On the other hand, when nurses become too dependent on technology, they can generate a lack of manual skills and a decrease in the ability to perform tasks without the help of it. Finding the right balance between the use of technology and humanized care is important to ensure that patients receive the attention and care they need in a safe and effective environment. In that sense, nurses must develop technological competencies effectively and responsibly, and to integrate it into their daily practice in a way that complements and enhances human care rather than replace it.
Performance Evaluation of State-of-The-Art 2D Face Recognition Algorithms on Real and Synthetic Masked Face Datasets

Published: May 2023

Face recognition systems based on Convolutional neural networks have recorded unprecedented performance for multiple benchmark face datasets. Due to the Covid-19 outbreak, people are now compelled to wear face masks to reduce the virus's transmissibility. Recent research shows that when given the masked face recognition scenario, which imposes up to 70% occlusion of the face area, the performance of the FR algorithms degrades by a significant margin. This paper presents an experimental evaluation of a subset of the MFD-Kaggle and Masked-LFW (MLFW) datasets to explore the effects of face mask occlusion against implementing seven state-of-the-art FR models. Experiments on MFD-Kaggle show that the accuracy of the best-performing model, VGGFace degraded by almost 40%, from 82.1% (unmasked) to 40.4% (masked). On a larger-scale dataset MLFW, the impact of mask-wearing on FR models was also up to 50%. We trained and evaluated a proposed Mask Face Recognition (MFR) model whose performance is much better than the SOTA algorithms. The SOTA algorithms studied are unusable in the presence of face masks, and MFR performance is slightly degraded without face masks. This show that more robust FR models are required for real masked face applications while having a large-scale masked face dataset.
Nature and Nurture? Comparing Lyα Detections in UV-bright and Fainter [O iii]+Hβ Emitters at z ∼ 8 with Keck/MOSFIRE
Authors: Roberts-Borsani Guido , Treu Tommaso , Mason Charlotte , Ellis Richard S. , Laporte Nicolas , Schmidt Thomas , Bradac Marusa , Fontana Adriano , Morishita Takahiro , Santini Paola
Published: May 2023

The 100% detection rate of Lyα emission in a sample of four luminous z ∼ 8 galaxies with red Spitzer/IRAC colors suggests objects with unusual ionizing capabilities that created early ionized bubbles in a neutral era. Whether such bubbles reflect enhanced ionizing properties (nature) or an overdense environment (nurture), however, remains unclear. Here we aim to distinguish between these hypotheses via a search for Lyα emission in five fainter galaxies drawn from the CANDELS-GOODS fields using a similar IRAC excess and UV magnitudes that should reflect reduced clustering effects. Using Keck/MOSFIRE we tentatively detect >4σ line emission in only two targets at redshifts z
Lyα
= 7.1081 and 7.9622 with rest-frame EWs of 16–17 Å, ∼1.5× weaker compared to their brighter counterparts. Thus, we find a reduced rate for Lyα emission of

0.40

−
0.25

+
0.30

compared to

1.00

−
0.44

+
0.00

for more luminous examples. The lower rate agrees with predictions from simulations of a mostly neutral intergalactic medium and an intrinsic EW0,Lyα
distribution for z ∼ 6 galaxies. However, even with an extreme EW0,Lyα
model, it is challenging to match the detection rate for the luminous objects. Spectral energy distribution fitting of our fainter sample indicates young and star-forming systems, albeit with less extreme star formation rates and ionization parameters compared to their luminous counterparts. The enhanced Lyα rate in luminous galaxies is thus likely a byproduct of both extreme ionizing properties as well as environmental effects. Further studies with JWST may be required to resolve the physical nature of this puzzling population.

Authors: Retamal Marco A. , Moyano Hugo I.
Published: May 2023

Using more than 200 genera and 431 species that comprise the 77 families of decapod crustaceans inhabiting Chilean waters, we attempted to reveal the underlying zoogeographical pattern of these taxa by comparing areas in terms of the number of shared species, genera, and families. To this end, the coasts and oceanic islands were divided into sixteen areas, encompassing most of the Nazca plate including Easter Island, Salas and Gómez Island, the Desventuradas Islands, and Juan Fernández Archipelago, as well as the underwater mountains of Salas & Gómez and Nazca (5 areas), the western coast of South America from Arica to Cape Horn (ca. 18°S-56°S; 10 areas), and the Antarctic peninsula and adjacent areas (1 area). The four resulting dendrograms coincided, showing six province: a) Chile-Peru (18º-42ºS); b) Magellan (42º-56ºS); c) Antarctica, including the Antarctic peninsula and the Scotia Arc archipelagos; d) Juan Fernández Archipelago (33º40'S; 79º00'W), including the Desventuradas Islands (ca. 26º20'S, 80ºW); e) Easter Island (27º09'S, 109º25'S); and f) the underwater mountains of Salas & Gómez and Nazca (ca. 25ºS; ca. 75ºW-100ºW). The dendrogram based exclusively on families inhabiting these diverse geographic areas identified two large clusters: the first encompassing the oceanic areas over the Nazca plate and the second the continental (10) and Antarctic (1) areas. In addition, decapod crustacean species of the southern tip of South America extend from the southeastern waters of the Pacific Ocean on one side of the Strait of Magellan to the southwestern waters of the Atlantic Ocean, reaching the Kerguelen Islands at the boundary of the Indian and Antarctic ocean.

Analysis of the relationship between relative abundance of mature, impregnated females of Pleoticus muelleri (Bate, 1888) (Crustacea, Decapoda) and environmental variables through statistical models
Authors: Fernández Mónica , Hernández Daniel , Roux Ana
Published: May 2023

The relationship between the relative abundance of mature and impregnated females of the Argentine red shrimp Pleoticus muelleri (Bate 1888) and environmental variables was analyzed using statistical methods. Analyzed data came from the research cruises of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) carried out during January 2000, 2001, 2005, and 2007; March 2006; and November 2004, 2005, and 2006 in San Jorge Gulf (Argentina). The biological variables considered were the relative abundances of mature and impregnated female shrimp, whereas the environmental variables corresponded to depth, bottom water temperature and salinity, and the difference between surface and bottom water temperature and salinity. Generalized additive models were used as an exploratory tool for the numerical data and the general linear models as a confirmatory tool. The results showed that the distributions and abundances of mature and impregnated females were related to the bottom water temperature and salinity and to depth. The relationship increased along with temperature; with salinity, however, it decreased for mature females and increased for impregnated females. An optimal depth range was evidenced, where the largest concentrations of these individuals were located.

Published: May 2023

The distribution of developmental stages of Sergestes arcticus, Neotrypaea uncinata and Munida gregaria larvae caught between Seno Reloncaví and Boca del Guafo in November 2004 was analyzed. Three oceanographic zones were distinguished according to records showing the degree of participation of continental and oceanic waters. Significant differences were determined between larval distribution and development stages for these species with respect to oceanographic characteristics; said differences might be related to the spawning sites and the habitat of the spawning stock in the study area.
Summer distribution of the southern stock of the Argentine hake (Merluccius hubbsi Marini, 1933) in the nursery area (44º-47ºS) in relation to oceanographic parameters (1996-2001)
Authors: Louge Elena , Reta Raúl , Santos Betina , Hernández Daniel
Published: May 2023

Summer temperature and salinity data in the nursery ground of the Patagonian stock of Argentine hake Merluccius hubbsi recorded from 1996 to 2001 were analyzed. These oceanographic variables were related to variations in the hake population abundance by means of a general linear model. Mean values and anomalies of bottom temperatures and salinity fields were determined. The most extreme positive thermal anomalies occurred in 1999 and 2000, whereas 1996 was the coldest year. The salinity anomaly was lowest in 1996 and highest in 2000. Argentine hake was found mainly in thermal and saline gradient zones. Juveniles were found mainly within the San Jorge Gulf with temperatures ranging from 8º to 10ºC and salinities of 33.2 to 33.6, whereas adults were located inside and outside the gulf, where bottom water temperatures oscillated between 8º and 12ºC and salinities ranged from 33.2 to 33.5. Juvenile densities were highest in shallower waters with higher salinities and lower temperatures than those inhabited by the adults. Adult hake were concentrated in the northern part of the Gulf and Camarones Bay, in shallow, relatively warm waters, as well as over the shelf waters off the gulf, where the salinity is low due to the drift of diluted waters from the Patagonian Current. The population distribution did not change in years with striking environmental anomalies.

BACKGROUND: Elderly patients are associated with an increasing prevalence of chronic degenerative diseases which need emergency services which can be a factor in the occurrence of potentially inappropriate medication (PIM). The use of PIM increases the risk of patients requiring hospitalization, drug-related problems, and adverse health outcomes with a prevalence of up to 2–3 times.
AIM: This study aimed to determine the possible incidence of admission and discharge events on PIM in Elderly patients (>60 years old) visiting the emergency department (ED).
MATERIALS AND METHODS: This is a retrospective and observational study at Universitas Airlangga Teaching Hospital in Surabaya for 4 months. This study involved Elderly patients who visited the ED. The 2019 Beers criteria were used to identify the use of PIM. Spearman rho analysis was used to determine the relationship between the possibility of hospital admission and the discharge of patients with PIM.
RESULTS: Most patients were female (50.4%) and aged 60−96. The percentage of elderly patients who received PIM and hospital admission was 73.1%, while those who received PIM and hospital discharge were 26.9%. The Spearman rho analysis showed a weak relationship between the  possibility of hospital admission or discharge (p-value 0.000, R 0.255) with PIM.
CONCLUSION: There is a weak but significant correlation between PIM and patient admission and discharge. Elderly patients are more at risk of being hospitalized due to PIM. The number of ED patients who received PIM had a high prevalence of being hospitalized compared to patients who did not receive PIM.
Ventilator-associated Pneumonia in the Intensive Care Unit of the Institute of Oncology Ljubljana in 2021 and the Role of Nurses in its Prevention
Authors: Medjedovic Sabina , Jurca Tomaž , Povšič Milena Kerin
Published: May 2023

BACKGROUND: Ventilator-associated pneumonia (VAP) is the most common infection in critically ill patients and has the highest mortality. It prolongs ventilation time and length of stay, increases antibiotic consumption, increases the likelihood of death, increases the cost of treatment, and is difficult to diagnose.
AIM: At the intensive care unit (ICU) of the Institute of Oncology, Ljubljana, we prospectively monitor risk factors for VAP and its incidence. It is a mixed surgical/internal ICU.
METHODS: A centers of disease control and prevention VAP diagnosis criteria and strategies to prevent VAP were used. Registered nurses recorded risk factors in all intubated patients in all three shifts, and the diagnosis protocol was completed by the physician in case of antibiotic administration in suspected VAP.
RESULTS: The expected incidence of VAP is around 18/1,000 ventilated days. In 2021, 67 patients were mechanically ventilated in our ICU (patients who completed ventilation in that year). The total time spent on ventilation was 17,143 h or 714.3 days. As the criteria for ventilator-assisted pneumonia (VAP) is >48 h of ventilation, we excluded 19 patients who had been ventilated for 48 h or less. Among 48 patients who were ventilated for > 48 h, the total ventilation was 16,765 h or 698.5 days. We recorded 8 VAP in 714 days, which is 1 VAP per 89 days of ventilation or 11.2/1,000 ventilation days. Healthcare staff, especially registered nurses, play a major role in VAP prevention, providing care every day, all days of the week. Most  prevention interventions and strategies are part of routine nursing care. Lack of knowledge about infection prevention and appropriate nursing care among nurses can become a barrier to adherence to evidence-based guidelines for the prevention of VAP.
CONCLUSION: This study will help nurses to learn about VAP and its prevention in detail so that they can apply the knowledge in clinical practice. Understanding the pathophysiology of VAP, its risk factors and the nursing care bundle is essential for appropriate prevention and treatment of VAP. Specific protocols, strategies, and active control should be available in each ICU regarding the care bundle.
The Effect of Prophylactic Central Neck Dissection during Total Thyroidectomy on Locoregional Recurrence in Patients with Papillary Thyroid Carcinoma: An Updated Meta-Analysis
Authors: Alayaaf Abdullah
Published: May 2023

AIM: The current systematic review was conducted to update the existing evidence regarding the association between prophylactic central neck dissection (pCND) and locoregional recurrence (LRR) in patients undergoing total thyroidectomy (TT).
METHODS: Studies were identified through systematic searches of electronic databases (PubMed, Scopus, Cochrane Library, and Clinical Trials.gov) between November and December 2022. The primary outcome was the unadjusted pooled estimate for LRR using an inverse variance – a weighted random-effects meta-analysis of odds ratios (ORs).
RESULTS: Twenty-two studies comparing pCND + TT and TT alone in cN0 PTC patients were analyzed. The meta- analysis included 6918 patients,  2796 cases in the combined group, and 3402 controls in the TT-alone group. The summary OR for overall LRR was not statistically significant, indicating a lack of additional benefit for pCND (OR = 0.76 95% CI [0.5–1.14], p = 0.18). Results were consistent for studies with an experimental or nonexperimental design. The rates of transient (OR = 1.81, 95% CI [1.36–2.41], p < 0.001) and permanent (OR = 2.56, 95% CI [1.72–3.8], p < 0.001) hypoparathyroidism were significantly higher in patients who underwent pCND. The rates of transient (OR = 1.71, 95% CI 1.24–2.35, p < 0.001) and permanent (OR = 2.12, 95% CI 1.29–3.45, p < 0.001) RLN nerve injury were also higher in patients who underwent pCND. Contradictory results were observed for adjuvant RAI with RCTs suggesting a lower need for postoperative RAI therapy.
CONCLUSION: The meta-analysis and the systematic review suggest that pCND was not associated with lower odds of LRR in patients with N0 PTC. Moreover, transient and permanent hypoparathyroidism and RLN injury were higher in patients undergoing TT + PCND. TT + pCND should not be routinely recommended except in high-risk patients due to the lack of benefit and lower safety profile than TT only.

L’autonomisation des femmes, une réponse à l’insécurité alimentaire en Afrique ?
Authors: Fall Marie , Jacquemot Pierre
Published: May 2023

Les femmes occupent sur le continent africain une place centrale dans l’agriculture vivrière. Elles sont incontournables dans les activités de transformation, de conservation et de commercialisation des produits vivriers. Elles sont au cœur de l’économie domestique et jouent un rôle social essentiel au bien-être des communautés rurales et urbaines. Pourtant, les femmes disposent de moins de droits sur la terre ; elles ont un accès plus limité aux informations et aux services ruraux ; et elles sont moins mobiles en raison des charges familiales. Plusieurs observations sur le rôle des femmes dans les périodes critiques, comme celle associée à la pandémie de la Covid-19 ou du bouleversement des marchés internationaux des produits agricoles et des intrants, éclairent d’un jour nouveau la réalité de la capacité des femmes à réagir pour lutter contre l’insécurité alimentaire avec une forte dose d’inventivité. Cette capacité est étroitement associée aux opportunités d’autonomisation économique et sociale qui leur sont offertes et qu’elles savent saisir et capitaliser. Une révolution silencieuse est peut-être en cours.
Le rôle des femmes dans la sécurité alimentaire urbaine à Ziguinchor (Sénégal)
Authors: Diédhiou Sécou O.
Published: May 2023

L’étude porte sur le rôle des femmes pour assurer l’essor de la production de produits vivriers dans l’aire alimentaire constituée dans et autour de la ville de Ziguinchor au Sénégal. Si dans le pays les hommes prédominent en tant que chef de ménage, cette situation est en partie inversée dans cette ville de Casamance où les femmes sont actrices principales dans l’essor de l’agriculture urbaine, particulièrement du maraîchage, de la riziculture, de l’exploitation et de la transformation de la noix de cajou. Le riz et les légumes produits en propre suffisent pour la satisfaction des besoins alimentaires de leur famille. Les revenus monétaires générés par les ventes sont significatifs. Ils ont été toutefois amputés de manière importante pendant la pandémie de 2020 à 2022.
La contribution des femmes dans l’approvisionnement en produits vivriers dans le département de San-Pedro (Côte d’Ivoire)
Authors: Hien Victorine , Adechina Olayossimi , Diomandé Souleymane
Published: May 2023

L’étude consiste dans un état des lieux des provenances des produits vivriers à San-Pedro en Côte d’Ivoire. Cinquante commerçantes ont été interrogées. L’analyse des fiches d’enquêtes a révélé qu’elles s’approvisionnent dans 26 villes pour les 22 produits vivriers les plus commercialisés. Parmi ces produits vivriers, 9 ont des lieux d’approvisionnement diversifiés, parfois lointains. La dégradation des produits vivriers, par manque de véhicules de transport appropriés, est un facteur très péjoratif. L’une des innovations mises en avant par les commerçantes, pendant et après la pandémie, est que les négociations d’achats et les commandes se font toutes désormais par téléphone.
L’inventivité des femmes transformatrices du riz : les unités d’étuvage de Bouaké, Daloa et Odienné (Côte d’Ivoire)

Published: May 2023

L’étuvage du riz reste le maillon faible de la chaîne de valeur du riz dans la politique de transformation locale du riz en Côte d’Ivoire. Le transfert de technologie permet de produire un riz local de qualité afin de le repositionner sur le marché de consommation. Un transfert de technologie d’étuvage amélioré GEM (Grain quality enhancer, Energy efficient and durable Material) est initié depuis 2017 par AfricaRice et l’État. L’étude montre que la diffusion de cette technologie auprès des femmes transformatrices a amélioré la qualité du riz étuvé et augmenté leurs revenus. Compte tenu du potentiel de cette nouvelle technologie et de l’engouement des femmes pour son utilisation, l’État devrait intensifier les actions de transfert dans toutes les zones productrices de Côte d’Ivoire.
Les combats ardus des femmes pour le contrôle des terres
Authors: Rédaction Afrique contemporaine
Published: May 2023

Alors que les stratégies de développement du monde rural ont intégré la présence des femmes dans des unités de production, l’idéologie localement dominante, d’essence patriarcale, établit encore souvent une autorité masculine sur l’attribution et la gestion des facteurs de production. La prééminence sexiste sur la gestion du foncier, des intrants, du crédit et des équipements se retrouve encore dans presque tous les contextes africains. Même lorsque la loi garantit l’égalité des droits, les femmes subissent souvent une discrimination de facto. La recherche de solutions repose sur un constat, celui de l’existence d’une corrélation entre trois éléments : les pouvoirs de décision dont jouissent les femmes, la quantité (et la qualité) des droits fonciers qu’elles détiennent et l’augmentation de la disponibilité locale en denrées alimentaires.
La « liberté des Argiens » (Tite-Live, XXXIV, 41) sous l’ imperium Romanum
Authors: Weber-Pallez Clémence
Published: May 2023

La cité argienne entre dans l’orbite de Rome dès 195 avant J.-C. en reconnaissant qu’elle doit aux autorités romaines la jouissance d’une « liberté » au sens encore controversé. Si les Argiens profitent de leur relation privilégiée avec Rome, qui les place comme intermédiaires principaux dans le monde achéen, ils n’en sont pas pour autant des acteurs passifs. Une étude de l’accueil fait aux Romains et une analyse des représentations mythologiques diffusées par les Argiens permettent de dégager une stratégie politique globale de la cité pour mieux intégrer et contribuer à façonner le nouveau système qu’est l’ imperium Romanum .
Les communautés de Romains sont-elles solubles dans la cité ? Cités égéennes, Rhômaioi et l’ imperium Romanum aux II e et I er siècles avant notre ère
Authors: Vlamos Alexandre
Published: May 2023

L’article s’intéresse aux relations entre les communautés de Rhômaioi installées dans les îles de la mer Égée et les cités qui les accueillent. En étudiant les banquets publics, je montre que ces cités, libres pour la plupart, ont la maîtrise des catégories d’étrangers, mais qu’il y a une évolution en lien avec l’installation de l’ imperium Romanum  : les Romains, d’abord intégrés aux autres étrangers, s’en affranchissent pour être inclus dans une catégorie à part. L’étude de la communauté romaine de Cos montre que les relations entre les Romains installés dans l’île et la cité dépendent de l’état de l’ imperium Romanum , entre violence des guerres civiles et pacification impériale.
Roman Power and the Memorial Turn in Civic Honourability in Western Asia Minor, ca 85 BCE-14 CE
Authors: Chin Marcus
Published: May 2023

Résumé Les honneurs accordés par les poleis hellénistiques à leurs bienfaiteurs ont longtemps constitué un moyen de créer une distance idéologique, intégrant le pouvoir des rois et des étrangers puissants, tout en maintenant l’action civique et l’autonomie. Quelles sont les évolutions sous la domination romaine ? Cet article suggère que les honneurs pour les magistrats romains, et plus tard l’empereur, ont contribué au cours du i er siècle avant J.-C. à modifier progressivement la conception des honneurs pour les citoyens locaux en Asie mineure occidentale : les objectifs traditionnels d’exemplarité et de reproduction sociale ont fini par être éclipsés, sinon remplacés, par celui de la commémoration individuelle. Ce processus s’est produit en deux phases dans la période allant de 85 avant J.-C. à 14 après J.-C. Dans la première, les bienfaits et honneurs accordés aux magistrats Romains en tant que représentants des intérêts civiques ont empiété sur ceux des notables civiques, entraînant une élévation du statut honorifique de ces derniers, et une tendance à souligner la mémorabilité de leurs accomplissements. Dans un second temps, l’apparition du principat et du culte impérial a imposé des limites au statut honorifique local et créé des hiérarchies honorifiques parmi les citoyens, autour des titres et de la primauté familiale, ce qui a mis l’accent sur l’individualité, au détriment de l’exemplarité.
L’entourage hellénophone d’Antoine et Octavien/Auguste. Transferts d’allégeance et processus de résilience
Authors: Bady Clément
Published: May 2023

La défaite d’Antoine et la disparition de la cour lagide ont entraîné une vaste recomposition des centres du pouvoir dans l’Empire autant que des entourages aristocratiques et auliques. Cette enquête reconstitue la trajectoire de Grecs appartenant à l’entourage proche ou lointain d’Antoine pendant et après le conflit triumviral. Il s’agit d’interroger et de comparer la résilience individuelle de ces acteurs hellénophones à travers la question du ralliement à Octavien/Auguste et de l’obtention ou non de sa clémence. Loin d’être linéaire et sans revers, leur processus de résilience s’appuie autant sur des acteurs intermédiaires que sur la capacité des espaces à marquer l’allégeance.
