Despite the amount of privatizations around the world in recent decades, only limited research attention has been paid to how privatization affects the employees. The effects are likely to vary depending on the individual's position in the organization. The aim of this study was to investigate how employees' work‐related attitudes and strain changed after privatization of a Swedish acute care hospital, and to analyze whether the effects of privatization differed between employees at various hierarchic levels. Questionnaire data collected at a hospital 1 year before and 2 years after privatization, as well as at a hospital which remained a public administration unit, suggest only limited effects of privatization on a general level, but that employees at various hierarchic levels may be affected differently. While employees at a high level (physicians) and low level (assistant nurses) reported only marginal differences over time in work attitudes and strain, also in comparison with their colleagues at the comparison hospital, work attitudes of employees at the intermediate level (registered nurses) decreased after privatization. These results emphasize the importance of taking hierarchic level into account when a privatization is implemented and analyzed.  相似文献

Borden’s (1979, 1980) hypothesis that speakers with vulnerable speech systems rely more heavily on feedback monitoring than do speakers with less vulnerable systems was investigated. The second language (L2) of a speaker is vulnerable, in comparison with the native language, so alteration to feedback should have a detrimental effect on it, according to this hypothesis. Here, we specifically examined whether altered auditory feedback has an effect on accent strength when speakers speak L2. There were three stages in the experiment. First, 6 German speakers who were fluent in English (their L2) were recorded under six conditions—normal listening, amplified voice level, voice shifted in frequency, delayed auditory feedback, and slowed and accelerated speech rate conditions. Second, judges were trained to rate accent strength. Training was assessed by whether it was successful in separating German speakers speaking English from native English speakers, also speaking English. In the final stage, the judges ranked recordings of each speaker from the first stage as to increasing strength of German accent. The results show that accents were more pronounced under frequency-shifted and delayed auditory feedback conditions than under normal or amplified feedback conditions. Control tests were done to ensure that listeners were judging accent, rather than fluency changes caused by altered auditory feedback. The findings are discussed in terms of Borden’s hypothesis and other accounts about why altered auditory feedback disrupts speech control.  相似文献

The present study is one of the first to empirically examine how the visual harmony of a questionnaire can lead to measurement bias. Researchers often employ questionnaires with Likert scales to measure constructs. In this note, we examine how the design of the survey instrument, specifically, its visual harmony, can impair measurement accuracy. Two studies investigate effects of visual harmony in surveys on responses to Likert scales using paper and pencil surveys. Applying an established customer relationship management model, Study 1 employs a survey of female visitors to a grocery store (n = 115). Switching to a product and brand innovation context, Study 2 employs a survey of male and female members of a consumer panel (n = 180) to examine responses to a new e‐scooter. Across studies, results indicate that assessing important consumer response constructs through visually more harmonious surveys can lead to more positive response patterns, lower scale reliability, and questionable validity, especially with females. Although these effects do not occur uniformly across measures and samples, they occur regardless of consumers' past experience with completing questionnaires, their familiarity with questionnaire design, and the naturalness and elaborateness of the visual design. Relating specific elements (e.g., text boxes, type font, shapes, and images) and relational properties of design (e.g., balance, symmetry, and coherence) to consumers' overall perception of harmony aids marketers and researchers in achieving intermediate levels to obtain realistic, reliable, and valid results.  相似文献

We present a conceptual framework on the experience of time and provide a coherent basis on which to base further inquiries into qualitative approaches concerning time experience. We propose two Time-Layers (Macro-Layer and Micro-Layer) and two Time-Formats (Flow and Structure) forming four Time-Domains. Micro-Flow and Micro-Structure represent the implicit phenomenal basis, from which the explicit experiences of Macro-Flow and Macro-Structure emerge. Complementary to this theoretical proposal, we present empirical results from qualitative content analysis obtained from 25 healthy participants. The data essentially corroborate the theoretical proposal. With respect to Flow, the phenomenally accessible time experience appeared as a continuous passage reaching from the past through the present into the future. With respect to Structure, the individual present was embedded in the individual biography, emerging from past experiences and comprising individual plans and goals. New or changing plans and goals were being integrated into the existing present, thus forming a new present. The future appeared as changeable within the present, by means from the past, and therefore as a space of potential opportunities. Exemplarily, we discuss these results in relation to previous empirical findings on deviant experiences of time in Autism Spectrum Disorder (ASD) that is presumably characterized by a breakdown of Flow and concomitant compensatory repetition resulting in an overly structured time. Finally, we speculate about possible implications of these findings both for psychopathological and neuroscientific research.  相似文献

When scaling data using item response theory, valid statements based on the measurement model are only permissible if the model fits the data. Most item fit statistics used to assess the fit between observed item responses and the item responses predicted by the measurement model show significant weaknesses, such as the dependence of fit statistics on sample size and number of items. In order to assess the size of misfit and to thus use the fit statistic as an effect size, dependencies on properties of the data set are undesirable. The present study describes a new approach and empirically tests it for consistency. We developed an estimator of the distance between the predicted item response functions (IRFs) and the true IRFs by semiparametric adaptation of IRFs. For the semiparametric adaptation, the approach of extended basis functions due to Ramsay and Silverman (2005) is used. The IRF is defined as the sum of a linear term and a more flexible term constructed via basis function expansions. The group lasso method is applied as a regularization of the flexible term, and determines whether all parameters of the basis functions are fixed at zero or freely estimated. Thus, the method serves as a selection criterion for items that should be adjusted semiparametrically. The distance between the predicted and semiparametrically adjusted IRF of misfitting items can then be determined by describing the fitting items by the parametric form of the IRF and the misfitting items by the semiparametric approach. In a simulation study, we demonstrated that the proposed method delivers satisfactory results in large samples (i.e., N ≥ 1,000).  相似文献

To ensure successful implementation of genetic screening and counselling according to patients best interests, the attitudes and motives of the public are important to consider. The aim of this study was to apply a theoretical framework in order to investigate which individual and disease characteristics might facilitate the uptake of genetic testing. A questionnaire using an extended version of the Theory of Planned Behaviour was developed to assess the predictive value of affective and cognitive expected outcomes, subjective norms, perceived control and uncertainty avoidance on the intention to undergo genetic testing. In addition to these individual characteristics, the predictive power of two disease characteristics was investigated by systematically varying the diseases fatality and penetrance (i.e. the probability of getting ill in case one is a mutation carrier). This resulted in four versions of the questionnaire which was mailed to a random sample of 2400 Norwegians. Results showed genetic test interest to be quite high, and to vary depending on the characteristics of the disease, with participants preferring tests for highly penetrant diseases. The most important individual predictor was uncertainty avoidance.  相似文献

The aim of the present study was to investigate the impact of part-whole (e.g., car-motor) and functional associations (e.g., car-garage) on single word (Experiment 1) and sentence production (Experiment 2). In Experiment 1, a classical picture-word task was used. In Experiment 2, the same stimuli and distractors were embedded into a sentence. The relation between target and distractor was either part-whole, functional or unrelated. At single word level, part-whole and functional relations facilitate naming. Additionally, the facilitation effect was stronger for part-whole in comparison to functional associations. During sentence production, facilitation shifted to interference. The difference between both relations disappeared. The findings of the different effects between functional and part-whole associations depend on the length of utterances and highlight the divergent impact of associations. The differences between part-whole and functional associations in single word production might reflect a differential organization of associative links at the conceptual level. In contrast, during sentence production the syntactic processing at the lexical level seem to be more important than types of semantic associations at the conceptual level.  相似文献

Previous findings on planning abilities in individuals with high-functioning autism spectrum disorder (HFA) are inconsistent. Exploring possible reasons for these mixed findings, the current study investigated the involvement of memory in planning performance in 15 children with HFA and 17 typically developing controls. In addition to planning abilities (measured with the Tower of London), short-term memory and delayed recall for verbal as well as visuospatial material were assessed. Findings suggest that particularly reduced efficiency in visuospatial short-term memory is associated with Tower task planning deficits in children with HFA.  相似文献
