Summary.In the expanding context of new literacies, the abilities to know how to locate and evaluate web information resources so as to construct knowledge are acknowledged as extremely important worldwide. Current literacy curricula should encourage the development of such abilities, and their successful implementation requires that teachers themselves are properly prepared. The present study reports the web searching and evaluating practices for educational purposes employed by both pre-service and in-service teachers. Data were collected via an anonymous online questionnaire. The descriptive study exhibits teachers' web reading practices with the purpose of identifying aspects that require attention when designing and implementing relevant educational initiatives. According to the findings of this research, both pre-service and in-service teachers almost exclusively use popular search engines to locate web information resources, and they choose such resources without examining their wider context. To evaluate web information resources, they consider mainly morphological and design elements, rather than content features such as their origin and credibility. The findings raise the potential of applying critical literacy principles on the Web so that teachers can approach it critiquely .i when using its resources in educational settings.

The main objective of this work is to obtain some new sufficient conditions that are essential for the oscillation of the solutions of forced nonlinear discrete fractional equations of the form ∆ ∆ µ (u(j)) + η(j)Φ(u(j)) = ψ(j), j ∈ N 0 where ∆ µ−1 u(0) = u 0 ; ∆u(j) = u(j+1)−u(j) and ∆ µ is defined as the difference operator of the Riemann-Liouville (R-L) derivative of order µ ∈ (0, 1] and N 0 = {0, 1, 2, • • • }. Numerical examples are presented to show the validity of the theoretical results.

The aim of this article is to describe the concept of professionalism, resulting from the practice perspective of a profession. Special reference will be placed on the medical profession and its dynamic role in the health system. Theoretical approaches regarding professionalisation, as a process through which a profession is achieving professionalism, as well as, mechanisms that contribute to the exclusion of other professionals to practice a profession are included in this article. Moreover, issues concerning the specific body of knowledge, autonomy, power and control, code of ethics and the regulation of entry by self-governing bodies, as well as the wide acceptance of society are all important in a distinctive occupational identity. Regarding the medical profession, the fact that decisions are made on patients behalf, results in a higher status among caring professions. On the contrary, for the same reasons there is criticism about the quality of its professionalism.
