Conclusion It follows from the proved theorems that ifM
=Q, (whereQ={0,q
1,q
2,...,q
}) is a machine of the classM
F
then there exist machinesM
i such thatM
i(1,c)=M
(q
i,c) andQ
i={0, 1, 2, ..., +1} (i=1, 2, ..., ).And thus, if the way in which to an initial function of content of memorycC a machine assigns a final onecC is regarded as the only essential property of the machine then we can deal with the machines of the formM
={0, 1, 2, ..., }, and processes (t) (wheret=1,c,cC) only.Such approach can simplify the problem of defining particular machines of the classM

The paper tries to develop Bartels’s modern essentialism as a structural-role theory of identity for spacetime points. I adopt Hoefer’s idea of denying primitive identity for this theory and apply it to GTR and prerelativistic physics to find different versions of essentialism and different definitions of determinism which are coherent with them. I also try to argue that modified essentialism helps us to refute objections raised against essentialism and offers us the best understanding of prerelativistic and relativistic theories. 相似文献

Since the burnout syndrome has a negative impact both on the individual affected and the institution in which he/she is employed, it is important to identify the factors which may alleviate the level of burnout. Social support is said to be one of such factors. Our study was undertaken to investigate the influence of social support in the workplace and general social support on relationships between global stress and stress related to role conflict, ambiguity, and overload and burnout components (emotional exhaustion, depersonalization, and personal accomplishment). The subjects were 1,023 hospital nurses. The results indicate that burnout level correlates highly with organizational and global stress. The role of social support in determining the level of particular burnout components varied according to the type and scope of support. No reliable correlation was found between emotional exhaustion and social support of any type. The level of depersonalization was related only to general support whereas a personal accomplishment factor was related to both types of support. The study did not reveal a buffering effect of both types of social support on the relationships between stress and components of burnout. 相似文献
