Fractional calculus is nowadays an efficient tool in modelling many interesting nonlinear phenomena. This study investigates, in a novel way, the Ulam–Hyers and Ulam–Hyers–Rassias stability of differential equations with general conformable derivative. In our analysis, we employ some version of Banach fixed-point theory. In this way, we generalize several earlier interesting results. Two examples are given at the end to illustrate our results.

Contributing to the efforts to foster business postgraduate students development toward becoming responsible business leaders is the goal of this study by examining the state of responsible management education in business postgraduate programs in Sudan. We examined perceptions and attitudes toward responsible management and its education among postgraduate-level students and constructed a comprehensive framework appropriate for developing responsible management education programs in under-developed countries. This study’s data were gathered via a structured questionnaire answered by 106 postgraduate business students from the (...) largest four Sudanese business schools and facilities. The students were distributed among the management, finance, and marketing fields. The students exhibited affirmative corporate social responsibility perceptions and attitudes with a heightened focus on acting ethically and a diminished focus on financial considerations. A key lesson learned from this study is the need for the continued development of CSR and general ethics across business school curriculums in Sudan. (shrink)

Most research reveals that television mainly confirms and re-inforces the existing party-preferences. Despite these findings, public opinion and especially politicians still believe in the direct effect of television on voter-decisions. Same researchers, among whom E. Noelle-Neumann, have given empirical evidence of strong influence of television on voter attitudes hut their findings have been widely contested.In recent years the topic is approached in a different way. The role of television in election campaigns was assessed in a broader context in combination with (...) other social factors and attention was no langer focused on the short term effect. The very high exposure to election programmes on television raises questions of motivation and use : for information, for entertainment, or as by-product of the television attachment. These different motivations imply different uses and consequently different effects, presenting a dillemma for broadcasters and politicians who have to produce programmes for all types of viewers. Many authors claim however that both broadcasters and politicians give in to the spectacular-entertainment side: more exciting debates, more shows, more uniformization of the political message. It should be stressed however, that television being the main source of political communication inelection periods, it can also re-open the issue of participation. Reinforcement of party-preference through television viewing can have a mobilizing effect, as latent party-preference can be turned into manifest voting behaviour.Finally the rules of the publicly controlled broadcasting institutions concerning election campaigns have undoubtedly had an institutional effect ; access and viewing-time are alloted according to the relative strength of political parties.

During recent years, the audiovisual landscape in Belgium has been going through a number of drastic changes.The monopoly of the public broadcasting system, standing for over 40 years, was breached. Several hundreds of private radio stations, two new commercial television stations and a number of private local television stations saw the light. The advent of all these newcomers has created a competitive media system. Therivalry between the public broadcasting companies and the commercial stations is very severe and unfortunately the PBS (...) are imitating the commercial model: they sacrifice more time for fiction and entertainment. Moreover, the Belgian media policy is very permissive and favours commercialisation. (shrink)
