    Purpose: The objective of this study is to know how we use can machine learning by applying different algorithms on the supply chain to produce in the cheapest site in the world considering different parameters.   Theoretical framework:  the study has highlighted the iterative queries of digital revolution in the supply chain. The literary view in this article has illustrated the significant role of machine learning and dark data in reducing the production costs, enhancing delivery performance.   Design/Methodology/Approach:  The company concerned by the case study is a multinational company specializing in flooring and sports surfaces. It operates in 33 production sites, with 520 sites in more than 100 countries.  One of the important factors underlying this complexity is the customer base that expects the product at the same cost all over the world, which forces the system that is currently not centralized to produce at a high cost in some countries.   Findings:  In this article, we use machine learning by applying different algorithms to unstructured data stored in company servers, where the feedback loop is implemented. The expected result is produced in the cheapest site in the world considering delivery costs.   Research, Practical & Social implications: We suggest a future research to use all the remaining dark data saved during ordering on the supply chain and to reduce  more the costs in the world .   Originality/Value: This article provides insights into how dark data analytics can be used to reduce supply chain costs and offers recommendations for organizations looking to leverage dark data in their supply chain operations

    The present study was aimed to evaluate the antimicrobial resistance and the presence of antibiotic resistance genes in Vibrios spp. isolated from seafood. A total of 72 isolates of Vibrio in 6 species including V. parahaemolyticus, V. vulnificus, V. alginolyticus, V. harveyi, V. mimicus and V. cholerae were examined. The results revealed that all isolates were expressing multiple antibiotic resistances. Of the 72 strains tested, 70 were resistant to ampicillin (97.2%), 60 to gentamycin (83.3%) and 56 to penicillin (77.7%). Eight strains were resistant to 4 antibiotic, 19 resistant to five antibiotics, 10 to six antibiotics, 34 to seven antibiotics and one to eight antibiotics. Results also revealed that 20 Vibrio strains (27.7% of total examined strains) contained one to three of the antibiotic resistance genes. StrB, tetS and ermB genes coding for streptomycin, tetracycline and erythromycin resistance were found in 18, 6, 5 isolates, respectively and Sulfamethoxazole resistance gene, sul2, was not detected in this study. Detection of resistance genes in Vibrio strains obtained from seafood is considered as a potential danger for consumers and also suggests that these resistance determinants might be further disseminated in habitats, thus constituting a serious health risks to human

    The Effect of Authoritarian Leadership on Human Resource Ostracism with Mediating role Emotional Burnout

    Employees are the main capital in order to achieve the goals and mission of the organization that the lack of proper communication and subsequent ostracism of employees and their isolation and frustration leads to dwstructive and undesirable consequences in government agencies. The study analyzes the effect of authoritarian leadership on the ostracism of human resources with the mediating role of emotional burnout. The peresent esearch is a descriptive- survey research in terms of applied purpose and in terms of method and nature. To measure the variables of authoritarian leadership, ostracism, and emotional burnout from the questionnaires of Wong et al (2019), Jiang et al (2011) and Swalqa (2017) was used. Validity and reliability of the questionnaires were confirmed through face validity and Coronbach’s alpha (0.82). The statistical population includes government agencies of Khorramabad city that 121 employess have been selected as a sample. Data analyzed through structural equation modeling. Analysis of rsults at %95 confidence level indicates a positive and significant effect of authoritarian leadership on ostracism and emotional exhaustion. Indirect path analysis reveals the mediating role of emotional burnout in the influence of authoritarian leadership on ostracism. As a general result, authoritarian leadership is considered as one of the underlying factors of emotional burnout and consequently ostracism of employees in government agencies

    The Mediterranean Sea is one of the busiest areas worldwide in terms of maritime activity and faces considerable anthropogenic disturbances, such as pollution by hydrocarbons and heavy metals. This study evaluated the environmental status of three sites on the Algerian coast using the annelid polychaete Perinereis cultrifera as a biomonitoring sentinel species. It included different reproductive parameters such as oocyte diameter, frequency distributions, sexual maturity index, biochemical quantitative parameters represented by the vitellogenins and vitellins, and a histological study of the coelome during the reproductive period. The results showed that the females collected from El-Kala (healthy site) have the highest diameter 304.1 ± 24.3 μm during April but the values were increased in Annaba 290.0 ± 21.0 μm and Skikda 245.3 ± 26.7 μm. Significant differences were observed between worms from the three study sites during the three months of the study. Moreover, the size-frequency indicated that a relatively high proportion of females containing mature oocytes was found in April in females collected at El-Kala 52.4%, 46.4% in females collected at Annaba and 36.7% in females collected at Skikda. In addition, regarding the sexual maturity index, the highest values were recorded in April (3.8, 2.9, and 1.9) at the El-Kala, Annaba, and Skikda study sites. However, the biochemical analysis demontrated that the highest mean concentration of vitellogenin was in females of El-Kala (5.3 ± 0.3 µg/mg of coelomic fluid) in April, and the lowest mean concentration was measured in females of Skikda (1.5 ± 0.2 µg/mg of coelomic fluid). Therefore, the highest mean concentration of vitellin was measured in females of El-Kala (4.4 ± 0.2 µg/mg of oocytes) in April, while the lowest mean concentration of vitellin was measured in females of Skikda (1.02 ± 0.2 µg/mg of oocytes) in May. Significant differences were observed between worms from the three sites during the three months of the study. Furthermore, histological observations revealed that oogenesis was asynchronous, with oocytes at different stages of vitellogenesis simultaneously present. The structure of the oocytes of females collected at El-Kala showed intense vitellogenic activity due to the presence of very dense yolk cells. In contrast, the oocytes of the females collected from the two polluted sites (Annaba and Skikda) were small, vitellogenesis presented low intensity, and yolk cells were less frequent at the periphery and less uniform at the cytoplasmic mass; the nucleus was smaller, indicating a slower vitellogenic activity. These observations confirm the previously obtained results

    Get PDF
    L’importance accordée par la littérature aux informations comptables n’est pas la même lorsqu’on fait une observation empirique. Ce constat nous a amené à réfléchir sur cette contradiction, l’objectif étant de voir l’importance accordée aux informations comptables dans les entreprises familiales camerounaises. Une enquête auprès de 61 entreprises familiales camerounaises nous a permis d’avoir, grâce au tri à plat, les résultats selon lesquels les entreprises familiales camerounaises respectent les normes et principes comptables en vigueur, et puis qu’elles produisent les informations comptables principalement pour satisfaire l’autorité fiscale. Nous avons également, grâce à la régression logistique, obtenu le résultat selon lequel, les caractéristiques propres aux dirigeants et à l’entreprise influent sur la production et l’utilisation des informations comptables
