Effets d'une perturbation anthropique sur les conditions hydrologiques de la langune de Smir (Nord-Ouest, Maroc)
La lagune de Smir a été sujette à un aménagement (construction d'un barrage et d'un port de plaisance) qui a contribué à la modification de son système hydrologique notamment, la disparition de certaines espèces de flore et de faune et la réduction de superficies considérables de cet écosystème.Une caractérisation des eaux de cette lagune a porté sur la mesure pendant le reflux, d'un ensemble de paramètres physico-chimiques. Une méthodologie a été suivie afin d'exprimer de façon cartographique les résultats. De même, des suivis d'une journée ont été réalisés pour les eaux entrantes et sortantes au niveau de deux stations fixes, dans une tentative de comprendre l'action de la marée sur l'hydrologie au sein de la lagune, de cerner les caractéristiques des eaux entrantes dans la lagune et celles sortantes de celle-ci et de suivre l'évolution des différents paramètres physico-chimiques au cours des cycles marégraphiques.L'évolution spatiale des paramètres hydrologiques au niveau de la lagune, se réalise sous forme de gradients entre l'aval et l'amont. Elle est fonction des saisons, de la marée et des apports de l'Oued Smir et du Chenal principal venant des marais. La lagune subit le flux et le reflux de la marée d'un mètre d'amplitude environ. Combinée avec le déficit en eaux douces, la communication permanente avec la mer a eu pour conséquence l'augmentation générale de la salinité dans le plan d'eau lagunaire et dans les marais. Le fonctionnement hydrologique de la lagune de Smir se trouve actuellement régi par les facteurs hydrodynamiques liés à la marée (réguliers) et aux apports d'eaux véhiculés par le chenal des marais (irréguliers), auxquels peuvent être ajoutés des facteurs physiques (évaporation intense), bathymétriques (faible profondeur) et physiologiques (photosynthèse des macrophytes et des phanérogames dans la lagune et dans les marais limitrophes).The Mediterranean Smir lagoon (35°43' N 5°20' W) is located in the extreme west of the Mediterranean basin, northwest of Morocco, 25 km south from the Gibraltar strait. The area of this lagoon is about 3 km2 with a maximum depth of 2.5 m. The bottom is dominated by silty and fine substrates with some sandy zones close to the entrance. The bottom is extensively covered with macrophytes (e.g., Enteromorpha and Ulva) and phanerogams (e.g., Rupia maritima and Zostera noltii). The lagoon receives water from the Smir Wadi but this input has decreased. It also receives fresh water via another channel (the marshes channel) from swamps that lie between the water body and M'diq city. This ecosystem has been subjected to unplanned dam and pleasure port constructions, and these changes led to a modification of the hydrologic system. Currently, this ecosystem communicates with the Kabila harbour (marina) and the sea across a narrow gully and is regularly subjected to tidal movements.This ecosystem, which functioned before as a lake, has been transformed into a coastal lagoon. This lagoon is changing and trends suggest a progressive evolution towards a neutral type lagoon, where water movement is exclusively influenced by the tidal rhythm. The salinity in the lagoon is comparable to sea salinity. This increase in salinity clearly influences the hydrologic conditions, and has altered the composition, structure and functioning of the biotic compartment. The biota has progressively changed and there has been a progressive colonization of halophyte plants within the marsh and a disappearance of fresh water species from the lagoon.The physicochemical parameters (salinity, conductivity, dissolved oxygen, pH, water temperature and sediment temperature) of the lake water were characterized. The methodology used allowed the results to be expressed cartographically. Similarly, the measurements for one day were analyzed for incoming and retreating waters at two stationary points, thus increasing the understanding of tidal action on the lagoon-lake hydrology.The salinity analyses clearly show a mixohalinity and strong spatial and temporal variabilities (9 - 40) within the lagoon. This parameter was influenced by tidal changes, rainfall and sunshine during the summer. The latter contributes to evaporation of lagoon water, which therefore increases salinity. Gradients established between the upstream and downstream regions are a function of tide and season. The salinity distribution is marked by maximum values recorded in the summer and minimum values recorded in the winter. The same evolution scheme evolution is also noticed for conductivity since it is a parameter closely linked to salinity.The lagoon and the main channel waters had higher salinity in the summer (S‰=40) due in part to marine waters that pervaded this channel, and the evaporation of inflow currents. Low salinity aureoles were detected in the Smir Wadi mouth indicating that fresh waters dilute marine waters. Marine waters that enter the Wadi channel by the inflow currents blend with fresh rainfall waters or stagnant saline waters or with groundwater inputs.Two periods were distinguishable based on the surface water temperature; hot summer conditions and cold winter conditions. The continental effect was compensated by the sea buffer effect that played an important role in the regulation of the temperature within the Smir lagoon. During the period of decreasing temperature gradients from the downstream region towards the upstream region (by stretching from sea towards continent), marine waters played a significant role by moderating the freshwater temperatures cooled down from the continent during cold periods (winter and autumn). In contrast, during decreasing temperature gradients from the upstream region towards the downstream region, the oceanic waters cooled the high temperatures of internal lagoon waters resulting from hot seasons (summer and spring). Furthermore, the shallow lagoon depth and the long exposure to sunshine, especially in the summer, resulted in water heating.In addition, the water temperature was influenced by hot marsh channel waters that occupy the upper region and spread with the low tide up to the lagoon entrance. Waters brought by the marsh channel also were distinguishable by high oxygen values, which demonstrate the role played by the swamp vegetation in the oxygenation of these waters. The low oxygen values recorded at the Smir Wadi mouth reflected the effect of suspended elements (turbidity). The Wadi contribution to the oxygen distribution in the lagoon waters was notable as it brings less oxygenated waters because of their strong turbidity.Nevertheless, the lagoon waters showed good dissolved oxygen saturation and no under-saturation was observed during the study period. This relates not only to the permanent exchanges with the sea, but also to the rather remarkable abundance of marsh vegetation and to the development of macrophytes and phanerogams within the lagoon. The dissolved oxygen isovalue distribution curves overlapped remarkably with isotherms, even as the temperature increased, because the entire zone that stretches up to the gully was occupied by a dense meadow. This biomass supplies oxygen to the central zone and can contribute to over-saturation. The lagoon inside was less covered with vegetation and showed comparatively low oxygen values. Besides the photosynthesis activity, the shallow depth and the uninterrupted lagoon waters mixed by the tidal currents explain the over-saturation sometimes observed within lagoon, especially in its downstream region.Variations in pH appeared to be closely linked to dissolved oxygen and water temperature. The three parameters present comparable distribution patterns showing the influence of the marsh waters on the lagoon hydrology. The pH varied between 8.0 and 9.0, demonstrating an elevated alkalinity in some lagoon waters. This alkalinity trend was due to the constant seawater entrance and to the stopping of Smir Wadi fresh water supplies.The sediment temperature measured at 5 cm deep gave insight into different daily and seasonal variations. The temperature of both air and marsh waters was comparatively well reflected in the sediments; the temperature distribution in the sediments overlaps with the water isotherms, with temperature values varying from 14 to 28°C. The inside part of the lagoon showed temperatures widely different from those recorded close to the entrance.The spatial evolution of hydrologic parameters in the lagoon resulted from gradients between the downstream and upstream regions. These gradients are a function of seasons, tide, Smir Wadi inputs and also the main channel coming from the swamps. The lagoon is subjected to high and low tides. In addition to freshwater shortages, the permanent communication with the sea resulted in a general increase of salinity in lagoon waters and marshes. The lagoon hydrologic functioning is currently governed by hydrodynamic factors that are related to the tide (regular) and to the fresh water supplied by the marsh channel (irregular). In addition, physical (intense evaporation), bathymetrical (shallow depth) and physiological (photosynthesis by macrophytes and phanerogams in the lagoon and the neighboring marshes) variables also influence the functioning of the lagoon

L’évolution de l’engagement envers la marque et son impact sur le comportement du consommateur
This article explores the concept of consumer commitment in general, as well as brand engagement, which is often confused with other constructs such as brand loyalty, further complicating its understanding. The aim of this article is to improve the theoretical foundations of the concept of brand commitment by developing its definition, the importance of its implications and differentiating it from other concepts. To do this, we have drawn on engagement theory, which emphasizes the idea that engagement with a brand is a dynamic, multidimensional process, and consumer-brand relationship theory, which views the brand as an entity with which consumers can have an emotional connection, mutual trust and long-term satisfaction. Our article focuses on the different dimensions of commitment, namely affective commitment, cognitive commitment and calculated commitment, its evolution over time and its influence on individuals' purchasing behavior. It first examines the cognitive, emotional and behavioral aspects that contribute to the creation of engagement between consumers and a brand. Next, the article explores the evolution of brand engagement over time, focusing on the impact of technological advances on consumer behavior. Finally, this article focuses on the impact of consumer commitment on purchasing behavior. We discuss some of the consequences of commitment: brand loyalty, repurchase intention, and willingness to pay more are all strongly influenced by brand engagement.
Keywords: Brand commitment, digital marketing, engagement theory, consumer-brand relationship theory, , loyalty, repuchase intention, willingness to pay more

Cet article explore le concept d’engagement des consommateurs de manière générale, ainsi que l'engagement envers une marque qui est souvent confondue avec d'autres construits tels que la fidélité à la marque, ce qui complique encore sa compréhension. Le but de cet article est d'améliorer les fondements théoriques du concept d'engagement envers la marque en développant sa définition, l'importance de ses implications et en le différenciant des autres concepts. Pour ce faire nous nous sommes basés sur la théorie de l’engagement qui met l'accent sur l'idée que l'engagement envers une marque est un processus dynamique et multidimensionnel, et la théorie de la relation entre le consommateur et la marque qui considère la marque comme une entité avec laquelle les consommateurs peuvent avoir une connexion émotionnelle, une confiance mutuelle et une satisfaction à long terme. Notre article se concentre sur les différentes dimensions de l'engagement à savoir l’engagement affectif, l’engagement cognitif et l’engagement calculé, son évolution au fil du temps et son influence sur le comportement d'achat des individus. Il examine d'abord les aspects cognitifs, émotionnels et comportementaux qui contribuent à la création d'un engagement entre les consommateurs et une marque. Ensuite, l'article explore l'évolution de l'engagement envers la marque à travers le temps, en mettant l’accent sur l'impact des avancées technologiques sur le comportement des consommateurs. Enfin, à travers cet article, nous mettons les points sur l'impact de l'engagement du consommateur sur son comportement d'achat. Nous évoquons certaines des conséquences de l’engagement, la fidélité à la marque, l’intention de rachat, et la volonté de payer plus sont fortement influencées par l'engagement à l'égard de la marque.
Mots clés : L’engagement envers la marque, marketing digital, théorie de l’engagement, théorie de la relation entre le consommateur et la marque, la fidélité, l’intention de rachat, la volonté de payer plus.

LES FACTEURS EXPLICATIFS DU COMPORTEMENT DU CONSOMMATEUR SUR UN SITE MARCHAND : PROPOSITION D’UN MODELE CONCEPTUEL
The consumer behavior on the Internet is often viewed as fundamentally different from that observed in a physical environment. It is characterized on the one hand by a great use of technology for transactions and on the other hand by distance, the impersonal nature of the online environment, temporal and spatial separations. This creates distrust and fear in the consumer. This reluctance creates difficulties for the survival of businesses practicing e-commerce. Hence the need to better understand and analyze the reasons why the consumer adopts or rejects the purchase on the Internet. A good understanding of the determinants of purchase intention online will allow these companies to adjust their strategies to attract the maximum of potential consumers and take full advantage of the opportunities offered by e-commerc

Structure et bioévaluation de l'état écologique des communautés benthiques d'un écosystème lagunaire de la côte atlantique marocaine
Oleoquímica I: Estudios sobre la preparación y la estructura de los jabones de litio.
Lithium stéarate, palmitate, myristate, laurate, caprate and caprylate were prepared by means of fusion method. Elementary analysis and the infrared absorptions spectra of the prepared lithium soaps as well as their X-ray diffractions and the thermogravimetric analyses were carried out. The anhydrous lithium salts of fatty acids with 12 carbon atoms or less showed thermal stability up to ca. 300 ± 78 °C depending on the chain length. On other hand the salts with 14 carbon atoms or more were decomposed at 126 ± 4 °C leading to formation of lithium carbonate. The homologous lithium soaps had very similar crystal structure among them and their metal -to- oxygen bonds were similar for the acyl chains between 8 and 18 carbons. However the angle of inclination of the molecular axes to the basal plane increased with the decreasing of the number of carbon atoms of the fatty acid chain, as determined by X-ray diffraction. In addition, the ionic character of the metal -to- oxygen bond was enhanced with the decrease of the number of carbon atoms as shown by infrared spectroscopy.Se han preparado estearato, palmitato, miristato, laurato, caprato y caprilato de litio por fusión. Se ha realizado el análisis elemental, los espectros de absorción en el infrarrojo y las difracciones de rayos X de los Jabones de litio preparados, además del análisis termogravimétrico de los mismos. Las sales de litio anhidra de los ácidos con 12 átomos de carbono o menos mostraron una estabilidad térmica hasta los 300 ± 78 °C dependiendo de la longitud de la cadena. Por otro lado las sales con 14 átomos de carbono o más se descompusieron a 126 ± 4 °C formándose carbonato de litio. Los jabones homólogos de litio mostraron una estructura cristalina similar, siendo los enlaces metal-oxígeno del mismo tipo para los ácidos grasos de número de átomos de carbono entre 8 y 18. Sin embargo el ángulo de inclinación que forma la molécula con el plano basal aumentó con la disminución del número de átomos de carbono, lo que se observó por difracción de rayos X. Se comprobó por espectroscopia infrarroja la intensificación del carácter iónico del enlace metal-oxígeno al disminuir el número de átomos de carbono
