Narrow Results

In this paper, we study to what extent decidability is connected to universality. A natural context for such a study is provided by the axiomatic theory of computability, automata and algorithms. In Section 2, we introduce necessary concepts, constructions, axioms, postulates, conditions and problems. Section 3 contains the main results of the paper. In particular, it is demonstrated (Theorems 1 and 2) that undecidability of algorithmic problems does not depend on existence of universal algorithms and may be caused by weaker conditions. At the same time, results of Theorems 2 and 3 demonstrate that decidability is incompatible with universality. It is also proved (Theorem 5) that sufficiently big classes of total algorithms/automata, such as the class of all primitive recursive functions, cannot have universal algorithms/automata.

This paper analyzes the motivations of eight female Afghan entrepreneurs to start up their own business and the problems they encountered during start-up and operations. Income generation was the most important push factor but pull factors including desire for independence and autonomy were also important. However, in contrast to studies in other countries, the desire for achievement was not emphasized. An unexpected finding was the emphasis on the desire to help non-family members by running a business. The main problems included financial problems during start-up and operations, lack of contacts and security during operations. Gender-specific problems included limited market, mobility constraints and negative attitudes and lack of social acceptance for female entrepreneurs. The paper concludes with a discussion of the findings.

In this paper, I examine three questions: (1) how creativity and innovation in organisations are defined in the scientific literature, (2) which theories are applied and hence which explanatory factors have been discussed, and (3) what the empirical evidence is regarding these factors. I uncover an overlap between the definitions of creativity and innovation, which in my view are distinct but related concepts. Further, despite the significant overlap in their definitions, research has evolved in two almost separate streams. Moreover, I observe that the multiple theories used (even regarding the same factor) to explain organisational creativity are not always integrated and that the empirical evidence about factors concerning individuals seems to converge but is much more mixed in relation to factors at the organisational level. Finally, I propose a new definition of organisational creativity and organisational innovation to distinguish them and suggest some avenues for future research.
