The role of physical design and informal communication

equirements, organizational requirements, interaction, and job
prestige/status. A Cronbach’s alpha value for the 48 items was calculated
to be .91, indicating an acceptable level of reliability.
2. A Comparative View of Employee Perceptions of their Workplaces as
Learning Environments (Coetzer, 2006). This survey was designed to
capture employee perceptions of their workplace as learning
environments. The questionnaire was divided into 5 sections: Employee
perception of work environment characteristics, supervisor’s proximate
support for learning, (dis) satisfaction with learning, perceptions of the
usefulness of seven “aids to learning,” and general information. The
measure of internal consistency reliability of the scale items was
satisfactory and exceeded the generally agreed upon lower limit for
Cronbach's alpha (0.70).
3. Measuring Organizational Traits of Hospitals: The Revised Nursing Work
Index (Aiken & Patrician, 2000). This paper describes how the Nursing
Work Index (NWI), developed by Kramer and Hafner (1989), was
redesigned to create the Revised Nursing Work Index (NWI-R). The
original structure of the NWI contained a comprehensive list of items that
provided the basis for the development of the NWI-R, which was designed
to measure aspects of a professional practice environment. Four subscales
were derived to measure organizational attributes that characterize
environments supportive of professional nursing practice: autonomy,
control over the work environment, relationships with physicians, and
organizational support for caregivers. Reliability of the instrument was
found to be acceptable with a Cronbach’s alpha of .96
