Les marquages corporels à l'adolescence : expression d'un mal-être profond? : se marquer pour se démarquer : du repérage des signes au choix des réponses adaptées

La problématique des marquages corporels en tant que pratiques ancestrales s'insèrent dans des formes contemporaines d'inscription corporelle. Nous nous sommes permis d'essayer de savoir s'il s'agissait toujours d'une expression d'un malaise psychologique important ? Quelles peuvent en être les conséquences ? Pourquoi marquer le corps ? La mise en oeuvre de ce travail s'est articulée en deux phases, au départ, nous avons opéré par une pré-enquête d'envergure qui a regroupé 200 adolescents (10 filles et 190 garçons). Ensuite et dans un deuxième temps nous avons interrogé dix adolescents qui se marquent la peau dont trois garçons, âgés de quinze à dix-neuf ans. Grâce à une « tri approche » : Entretien clinique, tests du Rorschach et du TAT. Les résultats auxquels nous sommes parvenus peuvent être résumés comme suit : ces pratiques expriment une souffrance qui peine à trouver une voie d'expression symbolique autre que le corps, l'angoisse et la relation d'objet du type anaclitique, l'organisation défensive renseigneraient essentiellement sur des défenses narcissiques, centrées notamment autour du clivage et le retournement sur soi, une identité fragile marquée par une image du corps et représentation de soi fragiles et un sur (dés) investissement des limites. Il s'agit d'une emprise sur le corps et sur les marques mêmes, permettant de retrouver l'objet et le recréer. À partir des principaux résultats obtenus, nous envisageons de travailler, en filigrane sur les spécificités des types de marquages corporels existant en Algérie. En effet si le présent travail s'est étayé sur une analyse prônant la globalité, un comparatif entre les types de marquages, de même, l'établissement d'un lien entre la symbolique de certaines pratiques et les soubassements psychodynamiques qui l'entourent, serait d'un apport considérable dans la compréhension du fait étudié dans ses moindres « recoins ». -- The problem of the physical markings as ancestral practices fit into contemporary forms of physical registration. We allowed to try to know if it was always about an expression of an important psychological illness? What can be the consequences? Why to mark the body? The application of this work articulated in two phases, at first, we operated by a large-scale pre- inquiry which grouped together 200 teenagers (10 girls and 190 boys). Then and in the second time we interrogated ten teenagers who mark the skin among which three boys, from fifteen to nineteen years old. Thanks to one « sorting approaches »: clinical Interview, tests of Rorschach and TAT. The results which we reached can be summarized as follows: these practices express a suffering which has difficulty in finding a way of symbolic expression other one than the body, the fear and the relation of object of the type anaclitique, the defensive organization would inform essentially about narcissistic defences, centred notably around the cleavage and the reversal on one, a fragile identity marked by an image of the body and the representation of one fragile and one on investment of the limits. It is about an influence on the body and on the marks, allowing to find the object and to recreate it. From the main obtained results, we intend to work, between the lines on the specificities of the types of physical markings existing in Algeria. Indeed if the present work supported on an analysis lauding the global nature, a comparative degree between the types of markings, also, the establishment of a link between the symbolism of certain practices and the bases psychodynamiques who surround him, would be of a considerable contribution in the understanding of the fact studied in its slightest « hidden recesses »

La particularité algérienne dans le phénomène chinafrique : Pourquoi ? & pour l’intérêt de qui ?

Africa, with its natural resources has become the catalyst for the functioning of the global economy, China has already understood and has taken the lead in conquering this gigantic market with over a billion consumers, while Western multinationals are relocating to China, China is abandoning them at home to relocate in this cradle that remains untouched to turn these resources on the spot to the finished products. Sino-African economic cooperation has grown in recent years. And China has become Africa's leading economic partner, a position it has held since 2009 to the detriment of the United States and Europe. This explains the emergence of the "Chinafrique" phenomenon. Algeria is a real example of the expansion of the economic "Chinafrique", with some specific peculiarities. The purpose of this paper is to give some answers to these questions: why do we talk about the "Chinafrique" phenomenon, Why Algeria is a particular case of the phenomenon "Chinafrique" and for whose interest the relations Sino-Algerian rock?

Influence of Saline-treated Wastewater on Properties of Concrete: An Experimental Study

The rapidly growing world population and the accompanying increase in concrete production to meet building and infrastructure needs have led to significant increase in potable water consumption, which resulted in several environmental problems. This paper investigates the feasibility of replacing potable water with highly mineralized treated wastewater in concrete mixing in order to make concrete production more eco-friendly in an arid region. Concrete specimens were prepared using saline treated wastewater (saline-TWW) as mixing water and compared to those mixed with distilled water (DW) and with the performance requirements given by the mixing water quality standards. The results revealed that the concrete mixes produced using saline-TWW exhibited higher early strength and a similar long-term strength than the control mix produced using DW. It was also found that the use of saline-TWW increased the setting times of cement paste but had no remarkable effect on the workability of fresh concrete mixture. Furthermore, the microstructural characteristics of the hardened concrete were assessed by water-permeability test, SEM image analysis, and X-ray diffraction tests. The results revealed that saline-TWW concrete exhibited a more compact microstructure and smaller pore sizes than their counterparts of DW, which means an improvement in the durability of saline-TWW concrete. Moreover, an electrochemical test was conducted to estimate the extent of corrosion of the steel embedded in reinforced mortar specimens prepared using saline-TWW and DW. The electrochemical test results showed that the use of 100% saline-TWW as mixing water of concrete resulted in a high corrosion rate of the embedded steel

الجامعة الجزائرية وتحديات تكوين الكفاءات في عصر اقتصاد المعرفة

This article aims to identify the most important challenges facing higher education institutions in general and the University of Algeria, especially in the formation and development of elite in the context of the transition to the knowledge society, considering that universities are the institutions responsible for the production of competencies needed by the job market as well as the quality. There is no doubt that the human resources required by the labor market in the age of the knowledge society are significantly different from what was required in the age of the industrial community or in the age of the agricultural community, and that overcoming these challenges is the best way to move to the knowledge economy

Study of the variability of cork growth in northern Algeria

The study of the growth of Algerian cork according to the concept of origin was carried out on 100 samples of 20x20cm representing ten production regions (El Tarf, Jijel, Skikda, Mila, Guelma, Bejaia, TiziOuzou, M'Sila, Hafir, Zarieffet). The caliber varies significantly from one to another (Origin 1). On average, it was about 29.75 mm with a still regressive aspect in the Western Region (Origin 2) and the Mountain Zone (Origin 3). The mean annual increments for an 8 year production cycle follow the same path, very significantly different between the samples of the Eastern Region (3,14mm year-1: El Tarf, Jijel, Skikda Guelma and Mila), the Central Region (3.19 mm year-1: Tizi Ouzou and Bejaia) and Western Region (2.64 mm year-1: M'Sila, Zarieffet and Hafir), a reduction of 12% in the Mountain Area. Growth indices were very stable for samples of origin1, shades and growth irregularities appear by applying the concept of origins 2 and 3. Regardless of the origin used, the indices of growth rate are type fast in Central and Eastern Region and middle type in the Western Region. This fact also applies to the Coastal Zone more than the Mountain Area.DOI: https://doi.org/10.5281/zenodo.81007

دور سياسة الإنفاق العام في تفعيل التنويع الاقتصادي - اقتصاد دولة الإمارات العربية المتحدة نموذجا -

In recent decades, the global economy has undergone profound transformations, which have made economic diversification a necessity and requirement for many countries, especially the mono-economic countries. In this context, the role of the State is growing and increase to laying the foundations for such diversification depending on its policy of expenditure, which is a strategic option, in contributing to the adaptation of productive activity not only to meet domestic needs but also to ensure greater competitiveness in international trade through the promotion and diversification of their exports, depending on what it contains of social or even military investment expenditures on the one hand, and their tax concessions and subsidies aimed at domestic and foreign investors alike on the other. As an example, we review the experience of the United Arab Emirates in economic diversification, which is a successful model that oil countries can benefit from

Etude des paramètres réglant la production du liège dans la subéraie de M’Sila (Oran, Algérie)

La productivité du liège  a été quantifiée pour la première fois dans la subéraie de M’Sila. Les calculs ont été adaptés  selon les trois  modes de gestion  existant dans cette forêt. Dans la station complètement embroussaillée et non anthropisée (Emb-1) et celle  complètement débroussaillée et anthropisée (Emb-1), la production  moyenne des arbres était faible (26,81kg/arbre et 29,77 kg/arbre), très influencée par l’altération sanitaire (ID=2,02 et ID=1,73). La concurrence accrue du sous bois et de l’enrésinement dans Emb-3 et le tassement du sol et de l’ensoleillement dans Emb-1 affectent  simultanément les performances physiologiques du chêne liège  en altérant  sa croissance radiale et subéreuse (circonférence, hauteur et épaisseur du liège). Paradoxalement, dans la station modérément embroussaillée et anthropisée, l’espèce est bien adaptée à son milieu en produisant un poids moyen de l’ordre de 43,46 kg/arbre avec un ID = 1,31. Ces résultats supposent que la problématique du déclin de la production du liège dans la subéraie de M’Sila est une question de gestion appropriée qui est défaillante depuis une quarantaine d’année. Les modèles de gestion qui associent  la mise en défend stricte et le pâturage et le débroussaillage contribuent, de façon significative, à nuire aux potentialités productives de ces peuplements précieux.

Mineralogy and quality of the cork according to the to the brushwood status in the oak cork forest of M'Sila (North-West of Algeria)

Cork is the bark of the cork oak (Quercus suber L.), it is a renewable product of a sustained value, and it is biodegradable and recyclable. Its use is diversified and its global demand is highly prized. The perfect knowledge of its various components allows better management of the species in the forest and in industry since it is marketed according to its visual quality. The present word studies the mineral composition of cork from 60 trees from two different natural environments, one is scrubby and the other is not scrubbed. The quality of the cork on the sample trees and the quality indices were estimated by the coveless. Analysis of variance of the mineral composition revealed that phosphorus and magnesium are attached to the underwood condition. On the other hand, only the potassium content significantly contributes to the cork quality classification and in lesser degrees the phosphorus. The growth complexity of the species and its genetic variability strengthen its great adaptation regardless of the vegetative conditions of the environment.Keywords:oak cork, cork, mineral composition, quality,  scrub-encroachmen
