Fostering Chinese firms through entrepreneurship, globalisation and international finance
The success of ventures that have pursued non traditional marketing approaches may be attributed to a range of forward thinking practices which it is argued here, should be the starting and finishing points for Chinese companies. Chinese multinationals need to develop entrepreneurial ability more compatible with their growth in the international markets. Chinas educational framework is still largely based on rote learning, which is a method typically seen as ill suited to modern needs. Many Chinese high tech sectors are still dominated by overseas know-how and the ongoing strength of wholly foreign- owned enterprises
THE EFFECTS OF ERROR NOTIFICATION TIMING ON ERROR CORRETION IN ROUTINE DATA ENTRY
Experienced data entry operators participated in an experiment to evaluate
the effects of the error notification timing on error correction performance irt
the data entry task. Three timing strategies were studied: immediate error
notification, notification at the end of a field, and notification at the end of a
physical line. Based on a model of data entry and a model of the correction
process hypotheses were developed to predict operator performance. It was
conjectured that operators treat individual fields as separate units tasks and
that interrupting within a task would be more disruptive than interrupting
between tasks. The results of the study indicated that the error rates during
correction were smaller for the end of line treatment although the time to
complete the correction was longer for this treatment than the other two.
Performance was essentially the same for those operators interrupted who
were interrupted immediately and those who were interrupted at the end of
a field.Information Systems Working Papers Serie
STRUCTURED ANALYSIS REPRESENTATIONS AS PRODUCTION SYSTEMS: AN INTERPRETATION AND ITS IMPLICATIONS
Much of transaction processing involves classification, that is, the categorization of
inputs into outputs based on various tests. In Artificial Intelligence (Al), classification
systems are generally represented in terms of AND/OR graphs. Such graphs are
collections of production rules that capture declaratively the logic of an application
domain. If one views a transaction processing system as a classification system, it
becomes natural to represent it in terms of an AND/OR graph. In this paper, we
present an interpretation of dataflow diagrams used in Structured Analysis as
AND/OR graphs. By examining the dataflow diagrams, production rules capturing
application-specific knowledge can be constructed. This interpretation has two
implications: 1) production rules can be used to unify analysis and design since the
same data structure (the rule) is used for both purposes, and 2) the resulting design
can be simulated for purposes of explanation and what-if analysis. We also discuss
some of the general pros and cons of production systems as they pertain to systems
analysis and design.Information Systems Working Papers Serie
ERRORS IN SPREADSHEET USE
Fourteen experienced users of two commercial spreadsheet packages, Lotus 123 and
Multiplan, performed four tasks - two of entering spreadsheets and two of modifying
those same spreadsheets. Their actions were videotaped and analyzed for incidents of
errors. Over 450 errors were made, the majority of them centered around the visual
properties of the spreadsheet packages. A classification of the errors is presented with an
analysis of the causes governing the production of the errors. A discussion of the choices
in the design of the interface which facilitated the production of these errors is also
presented.Information Systems Working Papers Serie

A METHOD FOR EVALUATING WORK GROUP PRODUCTIVITY PRODUCTS
Numerous software products claiming to improve work group productivity are making
their way into the marketplace. How is a manager to decide whether or not to invest in
these products? This paper proposes a suitable method of formulating the evaluation
problem for work group application products. The issue of normal software evaluation
is considered first. Then group work is described and contrasted with individual work
activities. A two-level evaluation strategy consisting of broad coverage and detailed
analysis is introduced. Detailed analysis consists of functional performance,
administration, and fit applied across task, group and communications domains.
Examples, drawn from some of the products demonstrated at this Symposium, are used
to illustrate how this methodology may be applied.Information Systems Working Papers Serie
China and international ownership: exploring consumer perceptions of brand equity and a new country of origin
Exploring perceptions of brand in country of origin. Many A2 Business Studies and Economics courses now have aspects of international business as part of the specification content. This article is a summary of work being conducted on the effects of changes in brand ownership on consumer perceptions. Emerging economies are not only developing their own businesses but also acquiring brand names and businesses from around the world. Will this have effects on the way consumers perceive these businesses and brands? Will it necessitate a change in global marketing strategies? This article outlines some of the thinking on these important issues. Some questions are provided to enable teachers to use the article with students in the classroom to promote thinking in this important are
