Tracking service failures and employee recovery efforts

Abstract: Demonstrates a method for examining service failures and recovery strategies in service industries and provides a typology of service failures and recoveries in the restaurant industry. Based on 373 critical incidents collected from restaurant customers, uses the critical incident technique (CIT) to identify 11 unique failure types and eight different recovery strategies. Additional data regarding the magnitude of the service failure, the service recovery rating, the lapsed time since the failure/recovery incident, and customer retention rates were also collected. Presents this information along with managerial and research implications.

Formulating clinical research hypotheses as structural equation models: a conceptual overview.

Abstract: Structural equation modeling is a comprehensive, flexible approach to research design and data analysis. Although in recent years there has been phenomenal growth in the literature on technical aspects of structural equation modeling, relatively little attention has been devoted to conceiving research hypotheses as structural equation models. The aim of this article is to provide a conceptual overview of clinical research hypotheses that invite evaluation as structural equation models. Particular attention is devoted to hypotheses that are not adequately evaluated using traditional statistical models.

The Price Bundling of Services: A Normative Framework:

Abstract: As product lines have broadened in many industries (particularly service industries), the use of mixed price bundling has increased. In mixed price bundling, a firm offers its customers the choice ...

Linear Electric Actuators and Generators

Abstract: Linear electric actuators and generators (LEAGs) are electromagnetic devices which develop directly short-travel progressive (or oscillatory) linear motion. Machine tool sliding tables, pen recorders and free piston power machines are typical industrial applications for LEAGs. Their recent revival in applications in compressors, pumps, electromagnetic valve actuators, active shock absorbers, vibrators, etc. Prompts this review, which presents main LEAGs configurations, their principles of operations, comparative performance evaluation, motion control and existing as well as potential applications.

Evolution on ecological time‐scales

Abstract: Summary 1Ecologically significant evolutionary change, occurring over tens of generations or fewer, is now widely documented in nature. These findings counter the long-standing assumption that ecological and evolutionary processes occur on different time-scales, and thus that the study of ecological processes can safely assume evolutionary stasis. Recognition that substantial evolution occurs on ecological time-scales dissolves this dichotomy and provides new opportunities for integrative approaches to pressing questions in many fields of biology. 2The goals of this special feature are twofold: to consider the factors that influence evolution on ecological time-scales – phenotypic plasticity, maternal effects, sexual selection, and gene flow – and to assess the consequences of such evolution – for population persistence, speciation, community dynamics, and ecosystem function. 3The role of evolution in ecological processes is expected to be largest for traits that change most quickly and for traits that most strongly influence ecological interactions. Understanding this fine-scale interplay of ecological and evolutionary factors will require a new class of eco-evolutionary dynamic modelling. 4Contemporary evolution occurs in a wide diversity of ecological contexts, but appears to be especially common in response to anthropogenic changes in selection and population structure. Evolutionary biology may thus offer substantial insight to many conservation issues arising from global change. 5Recent studies suggest that fluctuating selection and associated periods of contemporary evolution are the norm rather than exception throughout the history of life on earth. The consequences of contemporary evolution for population dynamics and ecological interactions are likely ubiquitous in time and space.
