Since measurement errors have strong effects in all relationships (statistical or otherwise) studied, there is an increasing interest in the data quality, which is the major justification for this research. This paper aims to present a new measurement procedure, the letter scale, which avoids many of the problems connected with the response modalities traditionally used in attitudinal research, especially the ordinal categorical scales. This paper analyzes the error composition of the scores obtained with this new measurement procedure. The validity of the procedure is also analyzed and the observed variance is assessed to determine which part of the observed variance is “valid”, which part is random error (attenuating relationships) and which is correlated error (magnifying relationships). Structural equation models will be used to provide estimates of the measurement quality: (i) Reliability, (ii) Construct validity, method effect and residual variance. In addition, this letter scale is evaluated under another different perspective, Information Theory measures are also used to assess the amount of information transmitted. The relative merits of this new measurement procedure as opposed to other common response modalities will be discussed in both cases. 相似文献

The clothing industry has been saved largely as a result of the introduction of new technology in response to an increasingly competitive market place. But what affect has this restructuring had upon jobs? We explore how women workers have experienced this change and why policy-making should consider job design. 相似文献

The paper contains a historical survey of consumer representation in the formation of British Standards and the establishment of the present Consumer Standards Advisory Committee (CSAC). The terms of reference and the methods of work are fully described and the importance of the safety aspect of BSI work is emphasized. The work of the CSAC in the formation of international standards is described and the paper ends with a discussion of the information and education activity necessary to ensure the recognition of standards by the consumer. 相似文献

All nurses are prepared to be generalists in palliative care. Within the discipline there are nurses who seek advanced educational preparation and develop clinical expertise in palliative care nursing. These are our leaders in palliative care nursing who can exert influence in all health care settings to support nurses providing palliative care. It is nurses and advanced practice nurses in partnership who are capable of developing and advocating for palliative care across settings. The focus of care is the person, not the diagnosis or the setting. The viewpoint that "all nursing care is palliative care" can transform health care with nurses taking the lead. 相似文献

Nursing unit volume-outcome relationships exist for patients assigned selected DRGs. This finding suggests that, in some cases, aggregating inpatients with similar clinical conditions may result in lower cost of care, shorter length of stay, and fewer hospital deaths. 相似文献

The sudden outbreak of severe acute respiratory syndrome (SARS) in Singapore in 2003 was a grave crisis for the tourism industry as a whole and highlights the importance of effectively managing and planning for such occurrences. This study looks at the particular consequences of the infectious virus for the hotel sector and reactions to the challenges posed. Further health‐related crises seem inevitable in the modern world and some guidelines for dealing with these are proposed, based on the Singapore experience and an existing framework for tourism crisis management.

This paper considers the challenges involved in the presentation of war as a tourist attraction, using the example of recent conflicts in Vietnam and a particular site there to illustrate the issues which arise. It begins with a general discussion about war and tourism, and then moves on to examine the development of tourism in Vietnam and the place of wartime heritage. Various aproaches to interpretation are identified and the problems facing those responsible are highlighted. The dilemma is one of achieving a satisfactory balance between education and entertainment while providing an appropriate experience for visitors who come with different needs and expectations. Political circumstances represent an added complication. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献
