This paper centers on the interpretation attributed by organizational members to the information systems (IS) alignment concept. Its objective is to study IS alignment in professional organizations. Specifically, it reports on an interpretive study conducted in five Chilean organizations; four professional and one entrepreneurial, of which two are private and three are public. The theoretical background of our study is derived from three IS strategic alignment conceptualizations: managerial, emergent and critical. These concepts formed our theoretical framework that guided data collection and analysis. The study centers on the meanings organizational members assigned to IS strategic alignment, as well as their views on the barriers that hinder achieving this level of organizational integration. The analysis results are summarized in seven hermeneutic themes that point out the different connotations the organizations assigned to IS alignment. The significance of the findings are summarized in four insights that formulate theoretical and practical implications. These insights refer to: (1) the difficulties of achieving alignment for professional organizations, particularly public ones, (2) the limitations these organizations have in being agile, (3) the rationale for acquiring technology and determining IT skills, and (4) the imperative meaning that CIOs attribute to IS alignment. The paper concludes with a reflection on the limitations and relevance of the research. 相似文献

We study possible rankings of opportunity profiles. An opportunity profile is a list of opportunity sets, one for each agent
in the society. We compare profiles on the basis of the notion of “equality of opportunities”. Our main results show the necessary
and sufficient conditions for this comparison to be made using exclusively the information provided by two cardinal measures:
the number of common alternatives in all sets of a given profile and the difference between the number of alternatives in
the individual sets. We also show that, under additional axioms, we can combine these criteria only in a weighted procedure
or in some lexicographic refinements of a weighted procedure.

This paper, following McGoun's (1997) seminal article comparing the economy of financial securities to a hyperreal poker game, argues that finance and accounting researchers should take the “linguistic turn” that has rejuvenated theory and research in many, if not most, of the social science and humanities in recent decades. In general terms, this means following Ludwig Wittgenstein's language game paradigm rather than Karl Popper's scientific deductive hypothesis testing methodology. The paper illustrates this by drawing on some of Jean Baudrillard's' ideas, particularly his concept of hyperreality and his phases of the image theoretic.The paper presents a poststructuralist genealogical analysis of the radical ruptures and reformulation of the meaning attributed to the accounting sign of earnings over the feudal, counterfeit, production, and simulation eras. It concludes that, as with many other signs in contemporary society, the earnings sign no longer has any relationship with, nor does it any longer refer to, any real or intrinsic profit but instead floats ungrounded in today's financial economy.The paper recommends that researchers in finance and accounting adopt paradigms from literary theory, semiotics, linguistics, and semiology rather than continue to rely on economics-based theory, which has lost its power for explaining and predicting happenings in today's financial economy of self-referencing models and images. 相似文献

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality
are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970)
has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem
of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way
ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the
most unity is uniquely DS-optimal.
Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also
thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments. 相似文献
