Are there major differences in the attitudes and service quality of standard and seasonal employees? An empirical examination and implications for practice

Despite the increased use of seasonal employees by organizations, few studies have been completed on the attitudes and service quality of seasonal office workers. Using Lautsch's classification model, we analyzed the organizational context in which the standard and seasonal workers in this study were employed. Hypotheses were developed based upon the organizational analysis and social exchange theory. Results from archival data obtained from a web‐based organizational survey of 205 clerical and professional workers indicated contrary to expectations, standard and seasonal employees did not significantly differ in terms of perceptions of overall job conditions, perceived organizational support (POS), or job engagement. However, seasonal employees did report significantly fewer opportunities to work on challenging tasks, less comfortable physical working conditions, and less job security than the standard workers. As predicted, standard employees reported significantly higher levels of service quality performance than seasonal employees. Additionally, job engagement mediated the relationship between POS and service quality for both the standard and seasonal employees. Implications for managing seasonal employees are discussed.     

曲面响应法预测砂浆性能的试验研究

本试验以砂浆性能为研究对象,采用Box-Behnken的中心组合实验设计及响应面分析方法对腻子粘结强度进行预测研究。试验选用三因素三水平的响应曲面分析法,建立了粘结强度的二次多项数学模型,并以粘结强度为响应值作响应面和等高线,考察了水粉比、灰粉比和胶粉比对粘结强度的影响,并根据实际选择响应曲面方程,利用最小二乘法估计相应的系数,剔除最不显著因素,建立最终的数学方程。结果表明:该预测模型能很好地描述粘结强度与水粉比、灰粉比和胶粉比之间的关系,可以对腻子粘结强度进行分析和预测,为砂浆性能研究提供一种新方法。

High-Performance HR Practices,Work Stress and Quit Intentions in the Public Health Sector: Does person–organization fit matter?

Drawing on the attraction–selection–attrition (ASA) framework, this paper examines a mechanism, namely person–organization (P–O) fit, through which high-performance HR practices (HPHRPs) affect two negative employee outcomes: work-related stress and quit intentions. Using a sample of Egyptian public health sector workers, a mediation model is tested empirically using structural equation modelling. The study results show that HPHRPs positively affected P–O fit, which in turn had significant negative associations with work stress and quit intentions. P–O fit also explained a high proportion of mediation in the relationship between HPHRP and both outcomes.

Schema strength,processing opportunity,and the rewarding nature of incongruity resolution in advertising

Extant literature calls for more research to identify the boundary conditions as well as the process underlying the effects of ad messages that violate specific brand beliefs. This paper examines different levels of ad–brand incongruity, considering brand schema strength and processing opportunity as factors that influence the perception and the resolution of incongruity. Moreover, it provides empirical evidence for the process mediating attitudinal responses to ad–brand incongruity. Experiment 1 shows superiority for moderately incongruent ads over congruent and extremely incongruent ads which is eliminated when participants have a weak, as opposed to a strong, brand schema. Experiment 2 replicates the nonmonotonic pattern for strong, real brands but further shows that low processing opportunity favors congruent ads. Mediation analysis reveals that the psychological satisfaction experienced during the ad interpretation process has an asymmetric mediating effect, such that moderate levels of ad–brand incongruity generate highest levels of satisfaction which then leads to more positive responses.     

Determinants hindering the intention of tourists to visit disaster-hit destinations

The purpose of this study is to propose and examine a new research model that is able to capture both the cognitive and affective components influencing potential tourists' behavioural intentions to visit a disaster-hit destination, which have negatively affected their perceived destination image. A survey of 357 participants provides strong support for the model. The results indicate that participants' perceptions of destination image are a strong predictor of their travel intentions. Factors relating to cognitive appraisals (e.g. perceived equipment risk, perceived natural risk and perceived social risk) as well as affective evaluations (e.g. perceived fear of ghosts, perceived unpleasantness, etc.) were found to be critical components that significantly, and negatively, influence potential tourists' perceptions of a destination image. Theoretical and practical implications of the results are discussed herein.     

Destination image,on-site experience and behavioural intentions: path analytic validation of a marketing model on domestic tourists

Despite its contribution to the national economy, domestic tourism is one of the most neglected and under-researched forms of tourism in the literature. This study tested an integrated path model examining the interrelationships between destination image, perceived quality, satisfaction and behavioural intentions, using domestic tourists who visited Eilat, Israel. The findings support the hierarchical relationships between image, quality, satisfaction and behavioural intentions. In addition, the affective image component was found to exert a far greater impact on the overall destination image than the cognitive component. The study establishes a better understanding of domestic tourists’ destination image and behavioural intention formulation. It also provides a number of implications for destination managers targeting the voluminous domestic segment.
