Although the core of most services is a person-to-person encounter, we still know very little about its underlying mechanisms as very few models or theories have been developed for these dynamic interactions between persons. An holistic approach to quality improvement is therefore suggested. Different prototypical person-to-person encounters may be studied on different levels and interfaces in service operations to eliminate inconsistencies. The aim of this contribution is to review some recent research findings for person-to-person encounters from the neighbouring management fields of services, operations and human resources in order to draw together their strategic implications for service managers. Some ontological and methodological considerations of studying person-to-person encounters from a qualitative perspective are discussed. The outline of a multi-disciplinary and learning-centred research approach is also suggested. Findings are integrated by a model of four generic and strategic processes for quality improvement in service operations. Finally, some implications for managers are proposed.  相似文献

We assess the value relevance of the amounts for identifiable intangible assets and goodwill reported in the financial statements of all non-finance companies listed on the main market of the Portuguese Stock Exchange from 1998 to 2008. Additionally, we use panel data to explore the impact on value relevance of Portugal’s formal adoption of International Accounting Standards [IAS] and International Financial Reporting Standards [IFRS] in 2005. A distinctive feature of the accounting by our sample companies is that when they adopted IAS 38 and IFRS 3 in 2005, they were no longer required to recognise some intangible assets (such as start-up costs and research expenditures) and were no longer required to amortise goodwill.We find that net earnings, reported goodwill and other intangible assets are highly significantly associated with stock price. However, whereas earnings are related positively to stock prices when Portuguese Generally Accepted Accounting Principles (GAAP) were applied prior to 2005, the value relevance of earnings appears to have declined after the adoption of IAS/IFRS in 2005. Although the change to IAS/IFRS had no impact on the value relevance of identifiable intangibles as a whole, the evidence suggests that there was a positive effect on the value relevance of goodwill. When the subclasses of identifiable intangible assets are considered, we found evidence of an increase in value relevance of goodwill, other intangible assets, and research and development expenditures.  相似文献

This study presents a characterisation of online reviews for small and medium hotels (SMH) in Portugal. We collected and analysed 1500 online reviews from 50 SMH. The findings show that room, staff and location were the concepts most frequently appeared in the reviews, with cleanliness, friendliness, helpfulness, and centrality of position the terms most frequently used to qualify the concepts. This study points out the main features which SMH managers should prioritize.  相似文献

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a lifecycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy – which became much more generous – and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement.  相似文献

A thematic balanced scorecard format was used to address environmental and social performance evaluation of 13 large companies operating in Portugal. Financial aspects of environmental and social company activities are also included. Companies were categorized as to their actual performance status using a predefined performance framework. Three categories were found: compliance with the law while emphasizing pollution control, pollution prevention and eco‐efficiency. Management tools and procedural matters were found to be most relevant for categorization. Often, reported information did not allow for quantitative evaluation of environmental burden reduction. Use of the thematic balanced scorecard format was useful to better understand the strengths and weaknesses of links between objectives and measurements, initiatives and achievements. Improvement as to environmental performance was found to be paralleled by increased social performance, suggesting that a multi‐level ‘sustainability’ performance categorization of these Portuguese companies is feasible. Driving forces for environmental management initiatives were found to differ by category of performance. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.  相似文献

Government permission is required to dismiss or lay off even a single worker in India and Zimbabwe. Dynamic labor demand equations, derived from a CES cost minimization model, are estimated for 64 manufacturing industries in these two countries. The data reveal a substantial reduction in demand for workers but no slowing in adjustment of number of employees following enactment of the labor laws. In India, no comparable reduction in labor demand occurred in small scale plants uncovered by the job security regulations. Among larger Indian plants, the drop in labor demand is estimated to be largest in industries where: coverage of the legislation is more extensive, private ownership dominates, and there are fewer union members.  相似文献

In the context of regularly varying tails, we first analyze a generalization of the classical Hill estimator of a positive tail index, with members that are not asymptotically more efficient than the original one. This has led us to propose alternative classical tail index estimators, that may perform asymptotically better than the Hill estimator. As the improvement is not really significant, we also propose generalized jackknife estimators based on any two members of these two classes. These generalized jackknife estimators are compared with the Hill estimator and other reduced-bias estimators available in the literature, asymptotically, and for finite samples, through the use of Monte Carlo simulation. The finite-sample behaviour of the new reduced-bias estimators is also illustrated through a practical example in the field of finance.  相似文献

Selling price,financing premiums,and days on the market   总被引:1,自引:1,他引:0  
Home buyers face the task of trading off selling price and the time required to sell a property. One factor that may affect this decision is the presence of financing premiums. The effects of financing premiums on the time a single-family home remains on the market is examined in this paper. The question is to what extent home sellers are willing to compromise on financing premiums and make concessions to buyers in order to sell their properties more quickly.The study uses a sample of single-family residential homes sold with assumption financing and new conventional financing. The sample covers segments of time when interest rates were relatively low and stable (1975–1976) and when rates were much higher on average and more volatile (1980).The results show that financing premiums were present in selling prices of assumption-financed home sales during the 1975–1976 period and that sellers were able to capture a premium and maintain the same average time on the market as properties with other types of financing. During a period of unfavorable market conditions, such as 1980, the results indicate that home sellers with assumption financing conceded or negotiated away any premium in order to significantly decrease the number of days their properties stayed on the market for sale.  相似文献
