Estimating climate influence of the potential covid-19 pandemic spreading in algeria
(Socioeconomic challenges, 2022-03-29) Fadel, Sabah; Rouaski, Khaled; Zakane, Ahmed; Djerboua, Asmaa
This document aims to investigate the potential influence of climate on the spread of the COVID-19 pandemic, the direct and indirect effects of climate are felt all over the planet, although their magnitude and manifestations vary. According to estimates by the World Health Organization (WHO), climate change could be the cause of nearly 250,000 additional deaths per year worldwide between 2030 and 2050 (Word Health Organization, 2021). This study focused on examining the relationship between climate (Temperature, humidity, and wind speed) and hospitalizations due to COVID-19 in a well-selected sample of wilayas in Algeria. In this brief, we want to shed light on the likely course and geographic spread of the epidemic. The purpose of this article is to answer the main question of the study: We do this by examining the effect of climate (temperature, humidity, and wind speed) on hospitalizations due to COVID-19 in the wilayas of Algiers, Blida, Oran, Adrar, Setif and Tamanrasset. The choice of wilayas is based on the availability, quality, and consistency of the data required. Our analysis suggests that high temperature and humidity or high relative wind speed tend to hamper the spread of the virus and that a high population density tends to facilitate its transmission. This does not mean that higher temperatures are enough to contain the disease. The climate potentially plays a role in the spread of many respiratory viruses. It appeared important to know if this could also be the case for the new coronavirus, COVID-19. While the role of climate in the transmission is still difficult to quantify, it is clear that other factors are taken into account in the transmission of COVID-19, namely mainly compliance with the rules of physical distancing and barrier gestures. This study focused more particularly on the effects of absolute climate (Temperature, humidity, and wind speed). 90% of infections would have occurred in areas where the temperature is between 3 and 17 degrees and the absolute humidity is between 4 and 9 g / m3, 35 to 85% relative humidity (Bukhari Q., Jameel Y., 2020). We address the issue of the impact of climate on the spread of COVID-19, we use the SUR (Seemingly Unrelated Regression) model to estimate the relationship between climate and COVID-19 cases in Algeria during the period between April 18th, 2020, and April 17th, 2021 inclusive. The results of the SUR model estimate, also showed that there is no real climate that can damage thepandemic situation in Algeria during the period studied
Digitisation of the justice sector in algeria: Reality and challenges
(Russian law journal, 2024-09-07) Boudebza, Djahida
Algeria has made significant progress in the field of digital transformation in the public service sectors, particularly that of justice, considered one of the sensitive sectors due to its link with individual freedoms.
Despite the great progress made in digitalization in this sector, their use by citizens remains limited due to the lack of digital culture among a large part of society, and the lack of knowledge of its advantages and guarantees, in addition to other economic and cognitive factors that must also be taken into account in the implementation of the National Digital Transformation Strategy 2024-2029
The impact of digital technology adoption on supply chain performance: A case study of sonatrach
(Journal of ecinomics and management, 2025-06-30) Adnani, Khawla; Mokedem, Abdeldjalil
This study rigorously examines the transformative impact of digital technology
adoption on supply chain performance within the specific context of Sonatrach, Algeria. It
directly addresses the pivotal question of how the strategic integration of advanced digital
technologies reshapes performance outcomes. A quantitative, correlational research design
is employed, analyzing survey data from 150 supply chain management professionals at
Sonatrach. Pearson's correlation and regression techniques rigorously assess the
relationships between adoption levels of IoT, remote sensing, Big Data analytics, and ERP
systems and key performance indicators. The findings emphatically demonstrate
significant, positive correlations between Big Data analytics and ERP adoption and
enhanced supply chain performance. These results underscore the crucial role of data-driven
decision-making and integrated systems, while also revealing vital areas for optimized IoT
deployment strategies to maximize their potential
Marketing practices for dairy products from small-scale farms, case: region of tiziouzou – Algeria
(Socioeconomic challenges,, 2021-12-30) Bouchetara, Mehdi; Mokhtari, Lyna; Lazreg, Messaoud; Zerouti, Messaoud; Iraten, Sabrina; Elmokretar, Lamia
The objective of our work is to identify the different marketing practices and to characterize the organizational constraints that hinder the productivity and profitability of small-scale livestock farms in the mountainous region of Fréha and Sidi-Naman, located in the region of Tizi-Ouzou, Algeria. Due to its high milk production potential, the targeted region was selected as a study area. The importance of our work lies in the determination of the key factors, which prevent small-scale milk producers from carrying out their livestock activities successfully. A quantitative questionnaire survey was conducted with 30 farmers. This study was complemented by interviews with livestock professionals. A documentary search of the literature and empirical studies was conducted, as well as site visits. The results show that there are several factors that impact on the normal course of productive activities of small-scale livestock farmers. The results show that there are several factors impacting on the normal production activities of small-scale farmers, such as: food and socio-cultural factors that are a constraint on milk production; distribution, which is strongly impacted by covid-19; lack of communication about products; and poorly organized marketing channels, especially in relation to goat farming, which accounts for 43% of our sample. We suggest that small breeders follow training courses on breeding methods and good practices, and improve hygiene and sterilization conditions on the farms, and strengthen the health control systems at the farm level. The contribution of the Algerian state for the regularization of the prices of animal products. To practice a good communication around the products processed by the small breeders to increase the marketing and sensitize the consumers to consume natural products. Exploit various other resources such as sheep milk by improving the dairy breeds of the region of Ouled Djellal. Orient goat farms towards intensive operations, and promote dairy breeds such as the Spanish Murciana and the French Saanen
Microcredit and multidimensional poverty in algeria : does gender matter? case study: national agency for management of credit / department of Boumerdes
(Management and entrepreneurship: trends of development, 2022-06-14) Hadefi, Abdelkrim Zoheir; Bouchetara, Mehdi; Zerouti, Messaoud
This article attempts to assess the impact of microcredit on the economic well- being and implicitly the degree of multidimensional poverty of women in Algeria. Based on data from a survey of 228 microcredit recipients in the department of Boumerdes in Algeria. The study showed that participation in microfinance services provided by the national agency for management of microcredit (ANGEM ) could be a tool for women to acquire the capacity to make strategic choices concerning their lives. By having access to microfinance services, women can set up their own businesses and consequently improve their status within the household and in their communities. Only 26 women participated in the survey. Using the Mann Whitney U test, the results show a significant difference between the impacts generated by microcredit on both genders based on the asset ownership index where female beneficiaries feel more impacted than male members do. These results call for further questions. ANGEM is not Micro-Finance Institution (MFI) like the others. It is a public agency
