Although gender is a salient variable in consumer research, researchers largely overlook whether, and how, it influences consumer response to indicators measuring latent variables. The authors therefore extend the framework of measurement equivalence assessment to the largely overlooked issue of differential item response behavior between men and women. This paper demonstrates the efficacy of using item response theory to investigate the presence of gender item bias. This methodological approach affords researchers the means of objectively disentangling actual gender differences and gender bias. Ignoring the possibility of gender item bias has the potential to bias means and thereby compromise any substantive gender-based mean comparisons. The authors conclude with solutions to address gender item bias both pre and post survey construction.  相似文献

Consumer involvement or patient and public involvement (PPI) in health research is a UK policy imperative and a prerequisite for many funders. PPI in research is defined as research carried out with or being carried out by the public (or service users), rather than research on patients and public as subjects or participants. Despite the clear policy driver, there is relatively little empirical evidence on the extent, processes and impact of user involvement in research. This paper aims to add to the international evidence base on PPI in research by providing a key overview of current trends and impacts. In order to understand the current extent and variation of PPI in research, a scoping exercise and survey were carried out on selected UK studies. Six research topic areas (cystic fibrosis, diabetes, arthritis, dementia, intellectual and developmental disabilities, and public health) were selected to ensure a range of designs, study populations and histories of PPI in research. A total of 838 studies (non‐commercial studies and not older than 2 years) were contacted. The response rate for the scoping was 38% and the survey 28%. In the scoping, 51% of studies had some evidence of PPI and in the survey 79%. The most common PPI activity was steering committee membership and reviewing patient information leaflets. There appeared to be some blurred roles with patients participating as research subjects as well as carrying out patient involvement roles. A major finding was the limited amount of available information about PPI in publicly accessible research documents. We suggest that the invisibility of this type of involvement and the lack of routinely collected information about PPI results in a lack of shared understanding of what optimal PPI in a study should look like, with important implications for practice. Furthermore, without a framework to review PPI it is difficult to know if different approaches to PPI have a different impact on key outcomes of the research.  相似文献

This article explores the production effects of the EU's system of decoupled payments and the implications for WTO negotiations. We compare survey data on Irish farmers' production plans post decoupling to the optimal outputs predicted by a farm-level profit maximisation model. The results show that, post decoupling, a significant number of farmers plan to use their decoupled payments to continue or expand economically non-viable production. An econometric analysis reveals that the decision to maintain or expand production levels post decoupling is not significantly influenced by current or future projected profitability levels. The analysis suggests likely widespread cross subsidisation of unprofitable production post decoupling but that aggregate production is still likely to decline relative to the traditional coupled, but production-limiting, blue box payments. If the EU wants to claim in the current WTO negotiations that decoupled payments amount to green box support, then the argument must be made that the payments have no, or at most minimal, trade distorting effects or effects on production. If it becomes apparent to members of the WTO that European farmers are using their decoupled income to subsidise market loss production, then the green boxing of the EU's decoupled payment scheme may come up for debate at the negotiations.  相似文献

ABSTRACT

This paper investigates the different relationships consumers build with anthropomorphised devices and how these relationships affect actual and intended future usage. An exploratory, three-week empirical study of 39 informants using voice controls on their smartphone uncovered a diversity of relationships that the informants built with such devices. We complement anthropomorphism theory by drawing on extended-self theorising to identify three primary roles that emerge from consumers’ interactions with these devices. Our findings theorise the distinct ways in which consumers perceive the object agency of anthropomorphised smart devices and how these perceptions impact the consumers’ engagement and future use intentions.  相似文献

Rice has been identified as an important food security crop in Ghana. However, there is a production deficit and new technologies to reduce the deficit are not widely adopted. Although poor adoption by farmers’ is often linked to constraints such as access to information, farmers’ perceptions of the technologies are also important. We apply an advanced discrete choice experiment to evaluate farmers’ preferences for rice production practices. Specifically, we generate willingness to pay (WTP) estimates using willingness to pay space (WS) and compare these with values from the indirect or preference space (PS) method. Our modelling also accounts for the effects on WTP estimates of farmers’ stated attribute importance (SAI) information. Empirical results from WS and PS models reveal that on average, farmers value higher yields and are negatively affected by higher risk of crop failure and labour requirements. Comparing the performance of the two models, we find the WS model provides a superior fit to our data and reduces the likelihood of producing implausible WTP estimates. Further, SAI inclusion did not produce much variation in our WTP estimates.  相似文献

Market segments based on the dominant movement patterns of tourists   总被引:1,自引:0,他引:1  
This paper presents an innovative method for tourist market segmentation-based on dominant movement patterns of tourists; that is, the travel sequences or patterns used by tourists most frequently. There were three steps to achieve this goal. In the first step, general log-linear models were adopted to identify the dominant movement patterns, while the second step was to discover the characteristics of the groups of tourists who travelled with these patterns. The Expectation–Maximisation algorithm was then used to partition tourist segments in terms of socio-demographic and travel behavioural variables. The third step was to select target markets based upon the earlier analysis. These methods were applied to a sample of tourists, over the period of a week, on Phillip Island, Victoria, Australia. A significant outcome of this research is that it will assist tourism organisations to identify tourism market segments and develop better tour packages and more efficient marketing strategies aligned to the characteristics of the tourists.  相似文献

The extent to which the intensity of R&D employees' interaction with market-oriented employees, proactive customer orientation, and responsive customer orientation affect the ability to reduce product-related uncertainties at the fuzzy front end of innovation was analyzed. They investigated 160 product innovation projects in various high-tech industries and identified proactive customer orientation as an important moderator of the link between R&D employees' interaction with market-oriented employees and the reduction of product-related uncertainties at the fuzzy front end. They also found that responsive customer orientation diminishes the ability to reduce product-related uncertainties at the fuzzy front end. The theoretical and managerial implications of the results are discussed.  相似文献

Wage structures in transition economies usually diverge significantly from their centrally–planned predecessors. Using a matched sample of employees and enterprises, we examine the effects of privatization on wage structures in rural industry in two provinces of China. We find that privatization was associated with increased wage and earnings inequality. We report increased returns to education, increased returns to experience for mid–age workers, and increases in gender wage discrimination. We find these aspects of wage structures are similar in different types of private ownership emerging from the reform process. JEL classification: P31, P23, P26 and J31.  相似文献
