Die politische Bipolarität der Gesellschaft hat dazu beigetragen, dass das ideologische Konkurrenzdenken sich auch in Literatur reflektiert, die wiederum die gesellschaftlichen Prozesse beeinflusst. Diese Gegensätze haben oft zu Katastrophen (Weltkriege) geführt, die die Autonomität des denkenden Subjekts: während die Moderne sich als Krönung der geistigen Evolution sieht und die Rolle der endgültigen Lösung für sich beansprucht, stellt die Postmoderne all das in Frage und lehnt Dichotomien der Moderne ab. Dagegen charakterisiert sich die Postmoderne mit Anonymität und Identitätslosigkeit, der postmoderne Mensch ist fähig alle Erfahrungen und Informationen des Alltags zu bearbeiten, sein Dasein ist endlich, seine Präsenz vergänglich, seine Möglichkeiten begrenzt. Diese Realität impliziert neue Bedingungen des Alltagslebens, des Arbeits- und Lebensprozesse, in dem das Individuum in einer Diskrepanz mit der wahrnehmbaren Welt existiert und den provisorischen Wahrheiten zum Opfer fällt. Die Degradierung des Individuums in einem passiven Wesen ohne Profil, bringt dazu bei, dass aufgrund diffuser Erfahrungen seinerseits die Wirklichkeit als Unechtheit, als Schein, wahrgenommen wird. Die Evolution der Postmoderne, so Lyotard, kann nur durch das Sprachspiel der Gesellschaft legitimiert werden, wohl gemerkt: das kann nur durch eine Konkurrenz der Machtspiele der Mitglieder zustande kommen.
In this paper we propose a cross-border analysis of the Spanish-Moroccan border, considering it such as “cross-border space” a field of interaction and cooperation between neighboring territories and communities. This relational perspective is rare in the analysis of this peculiar and controversial North-South border.\nIn our study, we consider the existing border asymmetries between both sides of the Spanish-Moroccan border not only as facilitators (as occurs in other international borders) but also as true motors-propellers of the profuse cross-border interactions that occur daily on the only land border existing between Europe and Africa\nRegarding the thematic content, we pay special attention to cross-border mobility, especially the existing institutional-regulatory framework that encourages and stimulates cross-border interaction. In addition, we review the main types of cross-border interactions observed on the Spanish-Moroccan border. While our main aim lies in the search for the engines that originate and drive these cross-border networks. The results of the analysis carried out seem to indicate that socio-economic asymmetries and border differentials existing between both border sides are the true drivers of the Spanish-Moroccan cross-border interactions
The implication of the corporate environmental activities on the corporate growth has been a contentious issue globally. The business activities of the organization affect its internal and external environments. The environment is under threat from the negative consequences resulted from the impact of corporate business activities on the environment. The cognizant of the negative impact of the corporate business activities on the environment globally has intensified the pressure on the corporate globally by the various stakeholders to engage in environmentally friendly business activities. Despite the fact that researches have indicated that it is in the best interest of the business organizations to take measures that would prevent environmental damages, some business organizations are not taking the call seriously. The corporate environmental activities have been linked to its growth. The environmental sensitive business organizations have seen increment in their performance while environmental insensitive business organizations have seen reduction in their performance. This study analyzed the implications of the corporate environmental reporting practice on corporate growth. The relevant literature on corporate environmental disclosure practice and corporate growth was reviewed and discussed, including the theory that underpins the study. It was established in the study that the growth of the business organizations heavily depends on their environmental activities. The study also uses the stakeholder theory to justify the rationale behind taking various stakeholders into consideration during the decision making process and not just only the shareholders. The study’s contribution to knowledge, limitation, and recommendation for further study were also discussed.
Huperzine is a traditional herb has also been explored for a number of pharmacological effects. Today, Huperzine has been observed for its nootropic effect. There is affluence of data regarding supporting the effect of Huperzine on human neuronal cells. The present study was designed to investigate the alteration in antioxidant defense system and nootropic effects after Huperzine exposure on human neuroblastoma cells IMR-32. The treatment of Huperzine was given for 24 h and cytotoxicity study was carried out by trypan blue dye exclusion assay. Apoptosis and necrosis were observed using Propidium iodide (PI) and Hoechst double staining method. Biochemical assays like total protein, protein carbonyl, lipid peroxidation and glutathione level were analyzed along with enzymatic activity of super oxide dismutase and catalase. Result of cytotoxicity showed dose dependent increase in percent viability and significant decrease was observed in percent of apoptosis and necrosis. Moreover, exposure of Huperzine significantly decreased lipid peroxidation and protein carbonyl formation along with the enhancement in antioxidant defense mechanism. Findings of these dose relviant toxicity study of Huperazine suggest that Huperzine has higher potency as a nootropic and causes repair of human neuronal cells IMR-32 cells enhancing the cell viability and consumption of Huperzine will help in prevention of CNS disorders and neurodegeneration.
The objective of this study was to assess the applicability of waste polypropylene (PP) and crumb rubber (CR) to improve performance properties of neat asphalt cement. Two CR contents (5 and 10%) and three PP percentages (2, 4 and 6%) were employed as asphalt modifiers. To obtain physical and compatibility properties of unmodified and modified binders, various conventional test methods such as penetration, softening point and storage stability tests were employed. Dynamic shear rheometer test was performed on unaged and PAV aged samples to achieve broad understating about rheological characteristics at high and intermediate temperatures. Findings of the physical tests represented a reduction in penetration and an increase in softening point by the polymer modifications compared with the neat one. Based on the rheological tests, the modifiers addition resulted in a reduction in phase angles, an increase in complex modulus at high temperatures, thereby decreasing binder sensitivity to permanent deformation. With increasing the polymers percentage, further improvement would be obtained regarding rutting resistance. At intermediate temperatures, however, complex modulus of modified binders decreased while no notable changes observed for phase angle in comparison with the base binder.
This study examines the impact of foreign exchange rate policy and gross fixed capital formation on the economic growth of Nigeria from 1989-2017. The Secondary data used for this study were obtained from the Statistical Bulletin issued by Central Bank of Nigeria. Linear regression model otherwise known as Ordinary Least Square (OLS) was used to analyze the collected data. The foreign exchange and gross fixed capital formation are the independent variables while real gross domestic product a proxy for economic growth is the dependent variable. The study revealed that there is a positive insignificant impact of foreign exchange on economic growth. However, the gross fixed capital formation has positive significant impact on the Nigerian economic growth. The finding of the study also indicates that both foreign exchange and gross fixed capital formation explain about 97% of the variation in the Nigerian economic growth. The study recommends that to reduce pressure on foreign exchange; government must encourage the consumption of consumer items being produced locally rather than the imported ones from foreign countries. The government also needs to enact favourable business rules and regulations that would encourage the investors to invest in Nigerian economy. This would increase the capital inflows thus provides the capital for the needed expansion of the economy.
The generation of reactive oxygen species (ROS) create oxidative stress in different pathophysiology conditions. The antioxidant compounds like Hibiscus sabdariffa (Hs, rosella, Malvaceae) react in one electron reactions with free radicals to prevent oxidative damage. Therefore, it is important to understand the reaction mechanism of antioxidants with the free radicals. Hibiscus sabdariffa was studied cyclic voltammetrically in 0.1M KBr solutions and using palladium working electrode. Many cyclic voltammetry waves were obtained at 290.75 K for different catalytic oxygen waves. The different cyclic voltammetry parameters were evaluated and discussed. The antioxidant capacity for Egyptian Hibiscus sabdariffa was estimated on comparison with standard antioxidant agent ascorbic acid cyclic voltammetrically.
The redox behavior data for thallous chloride using 0.1M HNO3 in absence and presence of polymer di ethyl amino ethyl cellulose were evaluated cyclic voltammetrically. Cyclic voltammetry of thallous chloride (TlCl) was achieved using glassy carbon electrode and in presence of di ethyl amino ethyl cellulose (DEAEC) as natural polymer. The cyclic voltammetry and the kinetic data for the redox reactions of TlCl was studied and their values were discussed.
