How uncivil customers corrode the relationship between frontline employees and retailers

This study investigates the effects of customers’ uncivil treatments on frontline retail employees’ emotions, deviant behaviors and relationship with the retail organization. Our theoretical model is based on both marketing and personnel management literatures. 415 frontline retailing American employees answered our questionnaire. Employees treated uncivilly by customers feel angry but have to hide their negative emotions, which leads them to emotional exhaustion and deviant behaviors. Paradoxically, employees’ strong commitment to their retailing organization brings about more deviant behaviors. We propose some managerial strategies to cope with uncivil customers, as well as future research on this important and under-researched topic.     

Individual differences in assessing problem similarity

This paper reports on a study which investigates the potential influence of perceptual differentiation (PD) ability on introductory accounting students' ability to identify and use analogies to solve problems. Accounting students with differing levels of PD ability first studied two sample problems with solutions which provided potential source analogues for analogical transfer. They then attempted to solve two analogous accounting problems differing only in the criteria for identifying problem analogousness. Findings suggest that PD ability may influence a problem solver's ability to identify analogous problems by affecting which problem features (surface or structural) he or she is likely to attend to and use for assessing problem similarity and potential analogousness. The paper concludes by discussing implications for pedagogical practices in accounting.     

Urban sprawl factors in the surface water resource basins of Istanbul

This paper presents the reasons for uncontrolled land-use changes in the water resource basins of Istanbul. These changes are evaluated with a Geographical Information System (GIS), using four Landsat (1990, 1995, 2000, 2005) satellite images. Additional spatial information about capital improvement projects (highways and the Bosporus bridges), industrial land-use decisions, land ownership, and jurisdictional boundaries is also utilized. We observe that the most critical land-use changes have occurred in places with higher accessibility, mostly in close proximity to the metropolitan city center. The literature describes large public capital improvement projects (primarily the Trans European Motorway – TEM) as the primary reason for a trend of illegal occupation of public lands; however, the TEM should not be considered as the sole reason. This study explores other possible causes for these illegal developments in the water resource basins, grouped into three broad dimensions physical, socio–economic–political, and legal. Finally, we put forward possible policy suggestions for the preservation of the limited surface water resource basins in Istanbul.     

New technology and the urban environment

Technology has always had an influence on the form of settlements, but only since the coming of Information Technology has it aroused much interest from academics and planners. The impact that IT is likely to have on urban areas is debated, some foreseeing decentralisation and the end of place, while others see evidence of the centralisation of control in a global economy. Other new technologies may also affect cities as new materials provide the opportunity for different styles of building. As we enter the 21st century, however, we do so with the largest stock of urban capital ever, much of which is ageing and in need of maintenance. Technology is part of a complex interrelationship of influences on urban areas and much of it will have to be retrofitted on to the pre-existing environment.     

ECONOMIC IMPLICATIONS OF POLICY RESTRICTIONS ON WATER WITHDRAWALS FROM SURFACE AND UNDERGROUND SOURCES

The appropriation of water for economic activities is limited by regional surface and underground endowments, and symptoms of environmentally unsustainable withdrawals are already visible in many regions of the world. In this paper we investigate the economic implications of water policy imposing source- and region-specific restrictions on water withdrawals taking the Mexican economy as a case study. We use an inter-regional input–output model of Mexico's hydro-economic regions to allocate production subject to the availability of water and other factors of production. Water sustainability requires a reduction of 7.5?km³/yr of groundwater withdrawals, which is compensated by an increase of 3.4?km³/yr of surface water, an expansion onto an additional 1.4 million hectares of rainfed land, and modifications in subnational patterns of food trade. This framework for evaluating scenarios describing sustainability-oriented water policies is readily applicable to other regions.

How emotional labor affect hotel employees’ mental health: A longitudinal study

The current study aims to examine the longitudinal effects of emotional labor on the mental health of hotel employees based on the Allostatic Load and Conservation of Resources theories. Four waves of data were collected from 534 hotel interns in an eight-month period. Latent growth modeling and lagged path analysis were used to analyze the time-series data. The study results indicated that hotel employees experienced increased anxiety and depression within the first three months of their new jobs. Surface acting increased employees' anxiety and depression. Interestingly, deep acting decreased employees' anxiety and depression in the short run but increased their anxiety and depression in the long run. Emotional exhaustion explained the double-edged effect of deep acting on mental health. The study results provide meaningful implications for hotel managers in workplace stress management and employees’ mental health improvement.     

Lagged effect of daily surface acting on subsequent day’s fatigue

The present research investigated the causal relationship between daily surface acting and fatigue at the within-person level. With a longitudinal approach – experience sampling method – based on 10 successive days’ data, this study explored the lagged consequence of service employees’ daily surface acting. The results of multilevel analysis showed that the daily performance of surface acting decreased service employees’ subsequent day’s emotional well-being in the form of increased fatigue. Further, sleep conditions were found to alleviate this detrimental effect. This within-person level investigation of the causal lagged effect of daily surface acting and its moderating contextual factor complements the current emotional labor literature that has overly focused on the between-person level. The theoretical and managerial implications were discussed.     

Exploring agricultural advice networks,beneficial management practices and water quality on the landscape: A geospatial social-ecological systems analysis

Agricultural practices have been linked to detrimental effects on ecosystems, with water quality of particular concern. Research has been devoted to understanding uptake of beneficial, or best, management practices (BMPs) in agriculture; however, sources of advice and subsequent effects on the landscape have not been elucidated. This study set out to understand (1) what sources of information agricultural producers rely on when making land-management decisions; (2) the characteristics of their advice networks; and (3) how the advice network linked spatially to water quality on the landscape. A watershed in Alberta was used as a case study and respondents identified that regional advisors were relied upon most often for advice and these advisors had the most influence on the adoption of BMPs. Results indicate that respondents with connections to regional actors implemented more BMPs that those without. Regional government actors had a greater effect than regional non-governmental actors. Local actors played a lesser role in advice networks related to BMP adoption. A 3D geovisualization was used to explore linkages among advisors, BMPs, and water quality. This technique may be useful for other scenarios and can contribute to policy development and enhanced practices.
