Comparison of four common data collection techniques to elicit preferences

We compare four common data collection techniques to elicit preferences: the rating of items, the ranking of items, the partitioning of a given amount of points among items, and a reduced form of the technique for comparing items in pairs. University students were randomly assigned a questionnaire employing one of the four techniques. All questionnaires incorporated the same collection of items. The data collected with the four techniques were converted into analogous preference matrices, and analyzed with the Bradley–Terry model. The techniques were evaluated with respect to the fit to the model, the precision and reliability of the item estimates, and the consistency among the produced item sequences. The rating, ranking and budget partitioning techniques performed similarly, whereas the reduced pair comparisons technique performed a little worse. The item sequence produced by the rating technique was very close to the sequence obtained averaging over the three other techniques.     

Transitions In the Psychological Contract: Some Evidence From the Banking Sector

This study examines the psychological contract in a sample of 107 employees in a retail bank. Deregulation, market-entry by non-traditional suppliers, and the introduction of advanced technology have changed the security of and rules implicit in the employment contract in the UK banking sector, which is one of the leading contenders for downsizing and delayering. Many banks are experiencing increased employee cynicism. New structures and technology, demanding levels of customer service, and new competitors have produced heightened attention towards performance and are associated with the need for employees to develop new competencies, such as relationship-handling and sales skills. Regardless of whether banks pursue high performance management systems or control-based HR strategies, the requirement for committed and engaged employees able to develop new competencies is an assumed constant. Demographic factors such as age, service and sex are found to be partial predictors of some attitudinal items. However, these proxy measures of attachment to the old employment deal are not related to items that consider commitment or satisfaction. the psychological contracts in the bank are highly fragmented. Seven underlying constructs are revealed: ‘frustratedly disengaged’, ‘still ambitious’, ‘passively flexible’, ‘guidance seekers’, ‘buy me outers’, ‘don't push me too fast’ and ‘just pay me more’. Implications of the research for HRM, the management of new internal labour markets in the banks and future directions of research on the psychological contract are discussed. It is concluded that a new set of internal labour markets are being created within the banks, the dynamics of which clearly revolve around a wide range of individual factors. Accepted wisdom about participative management practices will be challenged in the HR strategies of the late 1990s.

Are (active) entrepreneurs a different breed?

We present data from an incentivized online experiment and responses from a set of validated psychological questionnaires to measure entrepreneurs' risk and time preferences and to identify entrepreneurs' personality characteristics. The analyses of the data suggest that intrinsic motivation positively relates to the likelihood of owning a business (i.e., being an active entrepreneur). We also found that subjects who scored higher on drive were relatively more risk seeking while those who scored higher on pessimism were more patient. The results of our study highlight the importance of studying personality traits to better understand what drives people to own a business.     

Development and Psychometric Analysis of an Instrument to Measure the Reasons that Oncological Patients give when Participating in a Psychological Intervention

This work presents the psychometric study of a questionnaire on participation in psychological therapy (QPPT). The study is applied to oncological patients and the questionnaire was designed to evaluate the reasons given by chronic patients when participating or not in programmes of psychological treatment. The questionnaire includes six rational areas which resulted from the confirmatory factorial analysis.The internal consistency of the scales was analysed through Cronbach’s Alpha, and their discriminatory capacity between criterion groups of oncological patients was tested by means of t-tests and discriminant analyses. The results support, to a reasonable extent, the reliability and validity of the QPPT as an instrument to evaluate the reasons of participation or refusal of psychological treatment in oncological patients.     

Waiting Time and Production Uncertainty in Medical Services

To focus on office waiting time, the behavior of a medical practice is analyzed under a perfectly competitive setting where office waiting time is the only choice variable in the short-run. The optimum waiting time is determined for both the certainty and the uncertainty cases. Comparative statics are drawn with respect to the opportunity cost of waiting time, physician fee, capacity, and standard deviation of waiting time. Empirical analysis of waiting time is made based on questionnaires distributed among physicians and patients. The results are consistent with the majority of the theoretical findings.     

The applicability of the Tampa Scale of Kinesiophobia for patients with sub-acute neck pain: a qualitative study

The purpose of this study was to qualitatively evaluate patients understanding and interpretation of the wording used in test items of the Tampa Scale of Kinesiophobia (TSK). The TSK was developed to measure fear of movement in patients suffering from low back pain. The TSK is being increasingly used for other pain conditions. Patients with sub-acute neck pain experience problems while completing this questionnaire. The aim of this study was to elicit these problems. The study was conducted within the framework of a randomised controlled trial. The Three-Step Test Interview (TSTI) was used to collect data on the thoughts or considerations of respondents while completing the TSK. In the analysis, each transcribed interview was divided into three segments. The thoughts and considerations were then analysed and categorised per item. During the TSTI two problems were identified. One concerned the meaning of specific words used, like “dangerous” and “injury”. The other problem was that several implicit assumptions within some items make it difficult for respondents to answer these items. It was concluded that in the development and validation of questionnaires like the TSK, not only quantitative psychometric properties are important, but also qualitative research has an important contribution to enhance applicability.     

Applications of calendar instruments in social surveys: a review

Retrospective reports in survey interviews and questionnaires are subject to many types of recall error, which affect completeness, consistency, and dating accuracy. Concerns about this problem have led to the development of so-called calendar instruments, or timeline techniques. These aided recall procedures have been designed to help respondents gain better access to long-term memory by providing a graphical time frame in which life history information can be represented. In order to obtain more insights into the potential benefits of calendar methodology, this paper presents a review of the application of calendar instruments, their design characteristics and effects on data quality. Calendar techniques are currently used in a variety of fields, including life course research, epidemiology and family planning studies. Despite the growing interest in these new methods, their application often lacks sufficient theoretical foundation and little attention has been paid to their effectiveness. Several recent studies however, have demonstrated that in comparison to more traditional survey methods, calendar techniques can improve some aspects of data quality. While calendar instruments have been shown to be potentially beneficial to retrospective data quality, there is an apparent need for methodological research that generates more systematic knowledge about their application in social surveys.     

PREDICTING CORPORATE PERFORMANCE FROM ORGANIZATIONAL CULTURE*

This article investigates the relationships of culture strength and two substantive cultural values with corporate performance. Culture strength is measured by the consistency of responses to survey items across people and the two cultural values are measured by items on the survey that relate to either adaptability or stability. The data, from management surveys of 11 US insurance companies in 1981, were correlated with asset and premium growth rates from 1982 to 1987. Results indicate that both a strong culture regardless of content and a substantive value placed on adaptability are associated with better performance for two to three subsequent years on both criterion measures. The results support the findings of Denison (1990) that strength of culture is predictive of short-term performance. The present results, however, suggest a more complex contingency model than that proposed by Denison.

Healthcare information systems: data mining methods in the creation of a clinical recommender system

Recommender systems have been extensively studied to present items, such as movies, music and books that are likely of interest to the user. Researchers have indicated that integrated medical information systems are becoming an essential part of the modern healthcare systems. Such systems have evolved to an integrated enterprise-wide system. In particular, such systems are considered as a type of enterprise information systems or ERP system addressing healthcare industry sector needs. As part of efforts, nursing care plan recommender systems can provide clinical decision support, nursing education, clinical quality control, and serve as a complement to existing practice guidelines. We propose to use correlations among nursing diagnoses, outcomes and interventions to create a recommender system for constructing nursing care plans. In the current study, we used nursing diagnosis data to develop the methodology. Our system utilises a prefix-tree structure common in itemset mining to construct a ranked list of suggested care plan items based on previously-entered items. Unlike common commercial systems, our system makes sequential recommendations based on user interaction, modifying a ranked list of suggested items at each step in care plan construction. We rank items based on traditional association-rule measures such as support and confidence, as well as a novel measure that anticipates which selections might improve the quality of future rankings. Since the multi-step nature of our recommendations presents problems for traditional evaluation measures, we also present a new evaluation method based on average ranking position and use it to test the effectiveness of different recommendation strategies.     

The transformation of the wage and performance appraisal system in a Japanese firm

This paper analyses how performance appraisal has affected the wages of employees in a unionized Japanese firm over time, using firm-level wage and performance appraisal data. Data show that the wage and performance-appraisal systems have been shifting to a performance basis, and away from the heavy reliance on age and seniority characteristic of the old systems. In the process, wage differentials among employees are becoming wider, particularly among those 37 to 41 years old and those 49 to 55 years old. Management introduced the new wage system through a process of concessionary bargaining. Surprisingly, employees, rather than the enterprise union, were able to convince management to modify their initial plans during bargaining over the new wage system.

Perceptions of the mutual obligations between employees and employers: a comparative study of new generation IT professionals in China and the United States

This study examines the psychological contract from the perspective of new IT recruits that are located in the US and China. Psychological contract emphasizes the mutual exchange between employees and employers. Three hundred and ninety-five questionnaire responses from the graduating classes in the information technology discipline in the US and China (Shanghai and Beijing) were analysed. The results of this exploratory study reveal that new IT recruits from China and the US hold many similar beliefs on employer–employee obligations, such as employers' obligations to provide high pay, job autonomy, long-term job security, financial reward for obtaining IT certificates, exciting projects and opportunities to work on leading-edge technology, and employees' obligations to work extra hours when needed, to be loyal and to volunteer to do non-required tasks. Cross-cultural differences do exist however. US IT recruits as a whole place greater emphasis than their Chinese counterparts on rapid career advancement, having a motivating boss and completion of assignments on time, but less emphasis than their Chinese counterparts on receiving project milestone bonuses. Findings also suggest that, although employees can be from the same overarching culture such as the Chinese culture that emphasizes collectivism, there exist strong subculture differences even within the same country. New IT recruits in Shanghai tend to have beliefs that are at times closer to the US IT professionals than to their fellow IT new recruits in Beijing. The differences across cultures and subcultures are more extensive among female than male IT new recruits.     

Nonparametric estimation for a current status right‐censored data model

We consider the Case 1 interval censoring approach for right‐censored survival data. An important feature of the model is that right‐censored event times are not observed exactly, but at some inspection times. The model covers as particular cases right‐censored data, current status data, and life table survival data with a single inspection time. We discuss the nonparametric estimation approach and consider three nonparametric estimators for the survival function of failure time: maximum likelihood, pseudolikelihood, and the naïve estimator. We establish strong consistency of the estimators with the L₁ rate of convergence. Simulation results confirm consistency of the estimators.     

A resilience-based model for performance evaluation of information systems: the case of a gas company

Information systems (IS) are strongly influenced by changes in new technology and should react swiftly in response to external conditions. Resilience engineering is a new method that can enable these systems to absorb changes. In this study, a new framework is presented for performance evaluation of IS that includes DeLone and McLean’s factors of success in addition to resilience. Hence, this study is an attempt to evaluate the impact of resilience on IS by the proposed model in Iranian Gas Engineering and Development Company via the data obtained from questionnaires and Fuzzy Data Envelopment Analysis (FDEA) approach. First, FDEA model with α-cut = 0.05 was identified as the most suitable model to this application by performing all Banker, Charnes and Cooper and Charnes, Cooper and Rhodes models of and FDEA and selecting the appropriate model based on maximum mean efficiency. Then, the factors were ranked based on the results of sensitivity analysis, which showed resilience had a significantly higher impact on the proposed model relative to other factors. The results of this study were then verified by conducting the related ANOVA test. This is the first study that examines the impact of resilience on IS by statistical and mathematical approaches.     

The wording of questions in a CATI-based lifestyle survey: Effects of reversing the polarity of AIDS-related questions in continuous data

There is a need for reliable measurement of health-related attitudes and opinions in data which have been collected over time. The analysis presented concentrates on several questionnaire items from a lifestyle and health survey. The effect of changing the polarity of the questions is considered. This change was carried out during an 8-month period (involving 5,891 interviews) of a total of 23 months of observation (15,221 interviews). The main finding is that reversing the response direction of questions has different effects for different items. Time effects and socio-demographic characteristics have been considered as well as possible effects on items, but overall time trends are not affected.     

In search of content validity: facet analysis as a qualitative method to improve questionnaire design

In this paper, two scales are examined for the measurement of self-regulation. The item content is evaluated for its specific usefulness for measuring self-regulation of obesity patients. Qualitative facet analysis (QFA), an application of Guttmann’s Facet Theory, is used to investigate whether item content sufficiently covers the intended content area. This form of content analysis constitutes a systematic, effective and critical tool for improving the content validity of questionnaires. It discovers topics that are underrepresented or overrepresented. The method offers a way to clarify the relationship between concrete item phrases and the desired content as defined by construct and theory. It allows the researcher to improve his or her understanding of the items as a stimulus and of the similarities of items, and allows the formulation of a possible structure for confirmative factor analysis. Various ways to improve the content of both scales are identified.     

Consumption and labor supply

We present a new econometric model of aggregate demand and labor supply for the United States. We also analyze the allocation full wealth among time periods for households distinguished by a variety of demographic characteristics. The model is estimated using micro-level data from the Consumer Expenditure Surveys supplemented with price information obtained from the Consumer Price Index. An important feature of our approach is that aggregate demands and labor supply can be represented in closed form while accounting for the substantial heterogeneity in behavior that is found in household-level data. As a result, we are able to explain the patterns of aggregate demand and labor supply in the data despite using a parametrically parsimonious specification.     

New Nonlinear Approaches for the Adjustment and Updating of a SAM

Many structural relationships should be taken into account in any reasonable adjustment and updating process. These structural relationships are mainly represented by ratios of different types, such as technical coefficients or the proportion of the cell value in relation to its row or column total. We believe that in many cases (either because of lack of information or when the time elapsed for the estimation of a social accounting matrix is not long enough to allow for any significant structural change) the updating process should try to minimize the rela- tive deviation of the new coefficients from the initial ones in a homogeneous way. This homogeneity would mean that the magnitude of this relative deviation is similar among the elements of each row or column, therefore avoiding the concentration of the changes in particular cells of the SAM. In this work, we propose some new adjustment criteria in order to obtain a more homogeneous relative adjustment of the structural coefficients. These criteria combine the adjustment method proposed by Matuszewski et al. (1964) with other deviation functions. Each of the adjustment criteria proposed leads to a nonlinear optimization problem which is reformulated as a linear program. We test the usefulness of this proposal by comparing its results with the ones obtained by more standard approaches and we are able to show that these approaches tend to produce a less homogeneous pattern of coefficient adjustment, under certain circumstances, than the ones we put forward.
