    Environmental Impacts and Behavioral Adaptations of Honeybees in Algeria: A Review of Apis mellifera intermissa and Apis mellifera sahariensis Characteristics
    (Multidisciplinary Digital Publishing Institute, 2025) Haider, Yamina; Adjlane, Noureddine; Haddad, Nizar
    Honeybees are vital for pollination and the overall health of ecosystems. Since the 18th century, the intricate biology of honeybees has been a subject of scientific inquiry. Understanding their biological and behavioral characteristics is essential for effective beekeeping, honey production, and ecosystem sustainability. This review examines the environmental impact and management practices on the health of local honeybees in Algeria, focusing on Apis mellifera intermissa and Apis mellifera sahariensis. We summarize research findings on genetic diversity, morphometric traits, behavioral characteristics, and adaptation of local honeybees. Additionally, we discuss the threats posed by abiotic and biotic stressors and highlight the importance of conservation and sustainable management. The reviewed studies indicate that environmental factors significantly influence the behavioral characteristics and adaptation of local honeybees. Notably, the hygienic behavior of A. m. intermissa contributes to their resistance against diseases and the Varroa destructor mite. Further research in these areas is important for enhancing our understanding of honeybee health and population dynamics in Algeria, thereby informing strategies for sustainable beekeeping practices

    Socio-Demographic Determinants of Women’s Entrepreneurship: A Binary Logistic Regression Analysis
    (Academic Research and Publishing UG, 2025) Larbi Cherif, Hadjira; Badreddine, Amina; Sabri, Azzeddine
    Women’s entrepreneurship represents a critical economic driver for developing nations like Algeria, with significant potential to transform socioeconomic landscapes despite persistent barriers limiting female participation in business activities. This study utilizes data from the sixth round of the Multiple Indicator Cluster Survey (MICS6-2019), filtering a sample of 5,414 working women to investigate socio-demographic and economic determinants of women's entrepreneurial activities in Algeria. It was hypothesized that key socio-demographic factors, including age, marital status, residence, and living standards, influence women’s entrepreneurial inclination; educational level and vocational training significantly determine entrepreneurial participation; and government support programs contribute to increased female entrepreneurship engagement. Using binary logistic regression analysis with JAMOVI statistical software, the research reveals that only 13.2% of working Algerian women engage in entrepreneurial activities, with marital status, age, and educational level emerging as significant determinants. Specifically, married women demonstrate higher entrepreneurial participation than single women, younger women show greater entrepreneurial tendencies than older counterparts, and women with lower educational levels are more likely to pursue entrepreneurship than highly educated women. Contrary to expectations, vocational training, government support programs, wealth index, and geographical location (rural versus urban) did not significantly influence entrepreneurial engagement. This research opens avenues for further investigation into the psychosocial dimensions of women’s entrepreneurship in Algeria and calls for developing targeted interventions that address both structural constraints and individual capabilities to foster a more inclusive entrepreneurial ecosystem

    Women At The Crossroads Of Nationhood: Gender, Nationalism And Patriarchy In Post-colonial Algeria And Egypt
    (Université de Blida 2, 2025) Khireddine, Amel; Bouharrour, Karima
    Throughout history, Arab male nationalists have formulated a limited gendered conception of national identity wherein women are relegated to an inferior position. This paper is an attempt to shed light on the pejorative situation of Arab women during and after Western colonisation, represented here by Algerian and Egyptian women. Algerian women, whose role proved decisive in liberating their country, found themselves victims of their former male veterans who urged them to peacefully return to the household after decolonisation. With the rise of Islamic fundamentalism in the 1980s and the ensuing Black Decade, the situation of Algerian women, in a tremendously patriarchal oppressive society, further deteriorated. The situation of the Egyptian women was no better. While being fervent participants in the making of the Egyptian nation, Egyptian women fell under the subjugation of the patriarch who denied them all rights of equality both in the private and public spheres, following independence.

    Ethnobotanical knowledge and traditional uses of propolis among the Algerian population: a comparative and multivariate analysis
    (Ilia State University, 2024) Brahimi, Hibat-Allah; Oulebsir-Mohandkaci, Hakima; Hendel, Noui; Sarri, Madani
    Background: Propolis is a natural resinous substance collected by honeybees from tree buds and plant exudates, and is recognized for its beneficial biological properties. This study aims to provide a comparative overview of the various therapeutic, agri-food applications of propolis in Algeria, as well as the different forms and combinations with other natural products. Methods: This ethnobotanical study collected information on propolis use from 111 participants via semi-structured interviews. The data were analysed by calculating various parameters, including usage value and the relative frequency of citations. We used Multiple Component Analysis (MCA) and Principal Component Analysis (PCA) to determine all propolis properties. Cronbach's alpha analysis was used to assess the homogeneity of our survey. We used Pearson's test (α = 0.05) to test the relationship between propolis production parameters. Results: The ethnobotanical survey revealed that (73%) of participants possessed detailed knowledge of propolis' properties. The reported therapeutic benefits included support for the digestive system (40.5%), immune system (72%), along with wound treatment (66.7%). The study also found that, in Algeria, propolis is combined with other natural products (55.9%), to increase its effectiveness. With data reliability and homogeneity, analysis is shown to be stable and consistent across all questionnaire criteria. In addition, the Pearson test determined a correlation between the color of propolis in Algeria and the type of the plants. Conclusions: This study expands our understanding of propolis and its various uses, emphasizing its potential for development into pharmaceutical, dermatological and agricultural products

    Evaluation of the morphological and physicochemical diversity of carob (ceratonia siliqua, fabaceae) germplasm from algeria
    (Multidisciplinary Digital Publishing Institute (MDPI), 2024) Smaili, Oussama; Chebouti-Meziou, Nadjiba; Scollo, Francesco; La Malfa, Stefano; Gentile, Alessandra; Distefano, Gaetano; Luca, Leonardo Paul; Catalano, Chiara
    Despite the economic and ecological importance of the carob tree, few studies are available on the morphological characterization and chemical composition of carob in Algeria. This has resulted in the lack of selection of commercial cultivars of high seed and sugar content. The present study aims to assess the diversity of 11 wild and 1 cultivated carob populations in various regions of Algeria, characterized by diverse geographical and climatic conditions. The final objective is to assess the diversity of neglected carob plants that exhibit superior fruit quality traits and/or are well adapted to different pedoclimatic conditions. The current study focuses on analyzing pod and seed diversity by investigating 12 morphological and 5 physiochemical traits. The analysis of variance revealed significant differences between populations (p < 0.001) for all traits studied, indicating high morphological and chemical variability among these carob populations. Principal component analysis (PCA) was employed to study the relationship between these traits and the geographical origin. High seed yields characterized wild populations, whereas cultivated populations were rich in sugar. Based on morphological traits of pods, seeds and chemical compositions, a hierarchical clustering grouped the carob populations into four groups. The findings of this study represent a significant advancement towards establishing effective cultivar breeding programs in Algeria. They demonstrate that the germplasm examined in this research exhibits an optimal level of morphological and chemical diversity, which is instrumental in the identification of specific traits of both commercial and environmental significance.

    Molecular Surveillance of Yersinia pestis from Stray Dogs and Cats and their Fleas in Algiers
    (Razi Vaccine and Serum Research Institute, 2024) Zaidi, Sara; Bessas, Amina; Hezil, Djamila; Benseghir, H.; Bitam, Idir
    In recent years, plague has re-emerged in several countries around the world and remains endemic in some regions. In a natural environment, and in contact with rodents and their fleas, stray carnivores are most at risk of catching the disease and maintaining the spread of the bacillus. The objective of this study is to demonstrate the presence or absence of Yersinia pestis in stray dogs and cats in the Algiers region by molecular methods and thus contribute their role in epidemiology of this disease. Molecular research of Yersinia pestis has also been conducted on fleas from these carnivores. Preliminary identification of ectoparasites to genus and species level was performed. Real-time polymerase chain reaction targeting Yersinia pestis pla gene was used to survey the plague agent in fleas and carnivores captured as stray animals in Algiers (Algeria). Positive qPCR results were tested by PCR sequencing using glpD gene. Among 327 fleas captured from 107 dogs and 365 fleas from 140 cats, prevalence of Ctenocephalides felis was higher in cats (86,96%), whereas that of Ctenocephalides canis and Xenopsylla cheopis was higher in dogs (90,57% and 92,63% respectively). While internal and external PCR positive controls were positive, none of the 107 dogs spleen and 140 cat spleens and none of the 256 analyzed fleas were positive for Y. pestis. These results suggest that stray cats and dogs are unlikely sources for plague in Algeria contrary to that has been reported in other plague-endemic countries. This observation illustrates that plague epidemiological chain varies from one region to another

    Determinants of Household Poverty: Identification Using Logistic Regression
    (Academic Research and Publishin, 2024) Larbi Cherif, Hadjira; Badreddine, Amina; Sabri, Azzeddinne
    Abstract: The fight against poverty is considered one of the most critical tasks in achieving sustainable development goals. This study aims to identify the key determinants of household poverty in Algeria. The information base is data from the Sixth Cluster Survey (MICS 6) conducted by the National Statistics Office during 2018-2019 with a sample of 31,325 households in each province, which are divided into three groups (poorest, poor, non-poor) using a well-being index, which is based on the data about household assets and living conditions. Polynomial logistic regression was used to model the correlation between the poverty status of households and various demographic (household size, gender, age and education level of the head of the household), socio-economic (employment of the head of the household) and spatial (place of residence (urban/rural), region) characteristics. The results showed that a higher level of education of the head of the household significantly increased the probability of households moving from the "poorest" to the "poor" or "non-poor". As the age of the household head increases, the likelihood that the household will be non-poor increases. The gender of the head of the household was not a statistically significant factor. The increase in the number of dependents as a factor of creating additional financial pressure and falling into poverty is essential only in a situation of a very drastic change in status - when moving from the status of "non-poor" to "the poorest". In contrast, a slight change in well-being (a shift from "poor" to "poorest") is not associated with an increase in the number of household members. Modeling showed that extreme poverty is more common in rural areas than in cities. Regional differences are also revealed, as the poverty level is higher in the southern regions than in the northern ones. The slight increase in household welfare (transition from the category of "poorest" to "poor") in Algeria is not due to the economic activity of the head of the household. Still, it may be related to the nature of the analyzed data (only the fact of employment was considered without specifying the nature and type of activity). Instead, a significant change in welfare (moving from the category of "non-poor" to "poorest" households) directly depends on whether the head of the household is employed or unemployed. The results of the study are essential in the context of the development of a targeted policy to reduce the poverty risks of Algerian households: increasing the level of education and skills should be a priority, especially for young people and in disadvantaged regions, targeted programs for the development of rural areas and mechanisms for the fair distribution of public investments between provinces are needed to overcome regional disproportions.

    A comparative analytical study on Algeria’s performance according to the Arab Digital Economy Index during the period 2018 to 2022
    (M'hamed Bougara-Boumerdes Universty: Faculty of Economics, Commercial and Management Science, 2023) Boukezata, Salim
    This paper aims to analyze the reality and developments of the digital economy in Algeria, in light of the Arab digital economy index (from 2018 to 2022), and to compare its performance with the top eleven Arab countries. The study concluded that Algeria's performance according to this index was very weak, as it ranked last during the various years of the study.Furtermore, despite the improvement in Algeria’s performance in one of the key pillars of the index, which is digital infrastructure, this didn’t reflect positively on the performance of the other pillars such as digital government, innovation, knowledge and technology. The paper also detailed the various sub-indicators of these pillars showing the main weaknesses in the case of Algeria.
