Recovery Strategies (recovery + strategy)
Kinds of Recovery Strategies Selected AbstractsThe Effect of Competition on Recovery StrategiesPRODUCTION AND OPERATIONS MANAGEMENT, Issue 3 2006Mark E. Ferguson Manufacturers often face a choice of whether to recover the value in their end-of-life products through remanufacturing. In many cases, firms choose not to remanufacture, as they are (rightly) concerned that the remanufactured product will cannibalize sales of the higher-margin new product. However, such a strategy may backfire for manufacturers operating in industries where their end-of-life products (cell phones, tires, computers, automotive parts, etc.) are attractive to third-party remanufacturers, who may seriously cannibalize sales of the original manufacturer. In this paper, we develop models to support a manufacturer's recovery strategy in the face of a competitive threat on the remanufactured product market. We first analyze the competition between new and remanufactured products produced by a monopolist manufacturer and identify conditions under which the firm would choose not to remanufacture its products. We then characterize the potential profit loss due to external remanufacturing competition and analyze two entry-deterrent strategies: remanufacturing and preemptive collection. We find that a firm may choose to remanufacture or preemptively collect its used products to deter entry, even when the firm would not have chosen to do so under a pure monopoly environment. Finally, we discuss conditions under which each strategy is more beneficial.

Craighead Service failures do not need to result in permanent negative consequences as long as effective recovery activities are undertaken. Unfortunately, existing research has been limited in providing information to support prescriptive approaches for applying specific service recovery techniques. By using data from a large sample (n = 861) of service failure incidents and employing the use of hierarchical and non-hierarchical cluster analysis, this exploratory study creates and analyzes empirical types of service failures. The derived failure types, or common situations faced by service providers, focus on customer loyalty and the severity of the failure, and may be visualized in a two-by-two matrix. Regression analysis is then used to demonstrate how effective recovery strategies and supporting activities should vary, based on the location of the failure within the matrix. The approach and results offer important implications for strategy and service support activities as well as a foundation for systematizing service recovery efforts. [source] Another Breed of "Service" Animals: STARS Study Findings About Pet Ownership and Recovery From Serious Mental IllnessAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 3 2009Jennifer P. Wisdom PhD This study elucidates the role of pets in recovery processes among adults with serious mental illness. Data derive from interviews with 177 HMO members with serious mental illness (52.2% women, average age 48.8 years) in the Study of Transitions and Recovery Strategies (STARS). Interviews and questionnaires addressed factors affecting recovery processes and included questions about pet ownership. Data were analyzed using a modified grounded theory method to identify the roles pets play in the recovery process. Primary themes indicate pets assist individuals in recovery from serious mental illness by (a) providing empathy and "therapy"; (b) providing connections that can assist in redeveloping social avenues; (c) serving as "family" in the absence of or in addition to human family members; and (d) supporting self-efficacy and strengthening a sense of empowerment. Pets appear to provide more benefits than merely companionship. Participants' reports of pet-related contributions to their well-being provide impetus to conduct more formal research on the mechanisms by which pets contribute to recovery and to develop pet-based interventions. [source] Priorities and paradigms: directions in threatened species recoveryCONSERVATION LETTERS, Issue 3 2009Sue V. Briggs Abstract Recovering threatened species is a key challenge for conservation managers, policy makers, and researchers. This article describes a practical framework for assigning priorities for recovery of threatened species according to cost-effectiveness of recovery strategies for species groups. The framework has the following steps: (1) determine the conservation goal,persistence in the wild of the largest number of threatened species with the funds available; (2) assign threatened species to species recovery groups according to their characteristics and threats,small-population species that require actions at sites and declining-population species that require actions across landscapes; (3) identify the recovery strategies and their component actions for the species groups; (4) cost the recovery strategies for the species groups; (5) determine the cost-effectiveness of the recovery strategies for the species groups,the number of species recovered divided by the cost of the strategies; (6) assign priorities to the recovery strategies according to their cost-effectiveness; (7) allocate funds to the recovery strategies that maximize the number of threatened species recovered for the funds available; and (8) undertake the funded recovery strategies and actions. The framework is illustrated with an example.

[source] Perceived justice of service recovery strategies: Impact on customer satisfaction and quality relationship,PSYCHOLOGY & MARKETING, Issue 5 2010Rodolfo Vázquez-Casielles This article aims to build on previous research analyzing the effects of perceived justice on customers' satisfaction with service recovery and the attitudinal consequences of the recovery strategies firms adopt after service failures occur. The results obtained from a conceptual model developed for the mobile-phone sector support the idea that justice perceptions positively influence satisfaction with service recovery. Other findings are that satisfaction with service recovery positively affects trust and commitment, and that these two variables, in turn, positively affect overall customer satisfaction. Finally, the results also suggest that positive past experiences mitigate the effects of inadequate service recovery strategies on the quality of the relationship with the customers. © 2010 Wiley Periodicals, Inc. [source] Passive Restoration in Biodiversity Hotspots: Consequences for an Atlantic Rainforest Lizard TaxoceneBIOTROPICA, Issue 3 2010Agustín Camacho Guerrero ABSTRACT Long-term conservation in biodiversity hotspots depends on the recovery of communities in secondary forest fragments. In most cases, however, recovery strategies for these areas are based only on passive restoration. It is therefore necessary to determine the efficiency of such strategies. In this study, we assess the efficiency of passive restoration on a 567-ha 28-yr-old fragment of Atlantic Rainforest in Northeastern Brazil. We measured richness, composition, abundance and biomass of a lizard taxocene and also vegetation structure and availability of several microhabitat descriptors in 18 plots of this secondary forest. We then compared them with measures in 29 plots from two neighboring reference sites. Species richness, abundance, biomass and microhabitat descriptors availability inside the secondary fragment did not differ from reference sites. However, composition and vegetation structure showed small differences. Some forest specialist lizards, which should be a focus of conservation efforts in fragmented landscapes of the Atlantic Rainforest, were not found in the fragment and data indicate that this was not due to sampling or a lack of suitable habitat or microhabitat. In the presence of preserved source sites, passive restoration may be a cheap and effective way to recover lizard taxocenes of the Atlantic Rainforest. Some of the species may need to be re-introduced to accelerate the full recovery of original composition of lizard taxocenes in secondary Atlantic Rainforests.

Levesque This experiment examines the effectiveness of recovery stratégies after a service failure on customer loyalty and complaint intentions. Respondents encountered different core failures in ternis of problem severity (denial or delay) and criticality levels (high or low). The results suggest the effectiveness of service recovery strategies,assistance (fixing the problem) and/or compensation (defraying the costs incurred),varied depending on the txpe of service, problem severity, and criticality levels. The implication is that recovery strategies need to be matched to the specific incident. Service firms should focus on avoiding or reducing core failures. Getting it right the first time is the best strategy. Résumé La présente recherche examine au moyen d'une expérience l'efficacité de différentes stratégies de récupération sur la fidélité et les intentions de porter plainte de la clientèle à la suite d'une défaillance de service. Les participants ont été confrontés à différentes défaillances de service en termes de gravité (interruption du service ou délai) et de niveau critique (élevé ou faible). Les résultats indiquent que l'efficacité des stratégies de récupération,aide technique (résolution du problème) et/ou compensation financière (défraiement des coǔts encourus),varie en fonction du genre de service, de la gravité du problème et des niveaux critiques. Les résultats de l'étude laissent supposer que les stratégies de récupération doivent ,tre associées à un incident spécifique. Les entreprises de services doivent mettre l'accent sur l'évitement ou la réduction des défaillances. La meilleure stratégie consiste encore à donner le service correctement.

Carey Abstract Some properties of the integral superconvergent flux (post-processing) projection formula are investigated: (1) A Green,Gauss formula together with the partition of unity property of the finite element basis imply global and local conservation properties and a local flux or stress recovery strategy; (2) The equivalence to a Lagrange multiplier mixed formulation is used to interpret the associated consistency requirement on the flux expansion via an inf,sup or LBB condition and (3) The resulting conditions on the flux basis are examined and the presence of oscillatory modes demonstrated.

[source] Improving TCP performance over networks with wireless components using ,probing devices'INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 6 2002A. Lahanas Abstract TCP error control mechanism lacks the ability to detect with precision the nature of potential errors during communication. It is only capable of detecting the results of the errors, namely that segments are dropped. As a result, the protocol lacks the ability to implement an appropriate error recovery strategy cognizant of current network conditions and responsive to the distinctive error characteristics of the communication channel. TCP sender always calls for the sending window to shrink. We show that probing mechanisms could enhance the error detection capabilities of the protocol. TCP could then flexibly adjust its window in a manner that permits the available bandwidth to be exploited without violating the requirements of stability, efficiency and fairness that need to be guaranteed during congestion. Our experiments have three distinct goals: First, to demonstrate the potential contribution of probing mechanisms. A simple probing mechanism and an immediate recovery strategy are grafted into TCP-Tahoe and TCP-Reno. We show that, this way, standard TCP can improve its performance without requiring any further change. Second, to study the performance of adaptive strategies. An adaptive TCP with probing is used, that is responsive to the detected error conditions by alternating slow start, fast recovery and immediate recovery. An adaptive error recovery strategy can yield better performance. Third, to study the design limitations of the probing device itself. The aggressive or conservative nature of the probing mechanisms themselves can determine the aggressive or conservative behaviour of the protocol and exploit accordingly the energy/throughput trade-off.

[source] Application of a fuzzy logic control system for continuous anaerobic digestion of low buffered, acidic energy crops as mono-substrateBIOTECHNOLOGY & BIOENGINEERING, Issue 3 2009P. Scherer Abstract A fuzzy logic control (FLC) system was developed at the Hamburg University of Applied Sciences (HAW Hamburg) for operation of biogas reactors running on energy crops. Three commercially available measuring parameters, namely pH, the methane (CH4) content, and the specific gas production rate (spec. GPR,=,m3/kg VS/day) were included. The objective was to avoid stabilization of pH with use of buffering supplements, like lime or manure. The developed FLC system can cover most of all applications, such as a careful start-up process and a gentle recovery strategy after a severe reactor failure, also enabling a process with a high organic loading rate (OLR) and a low hydraulic retention time (HRT), that is, a high throughput anaerobic digestion process with a stable pH and CH4 content. A precondition for a high load process was the concept of interval feeding, for example, with 8 h of interval. The FLC system was proved to be reliable during the long term fermentation studies over 3 years in one-stage, completely stirred tank reactors (CSTR) with acidic beet silage as mono-input (pH 3.3,3.4). During fermentation of the fodder beet silage (FBS), a stable HRT of 6.0 days with an OLR of up to 15 kg,VS/m3/day and a volumetric GPR of 9 m3/m3/day could be reached. The FLC enabled an automatic recovery of the digester after two induced severe reactor failures. In another attempt to prove the feasibility of the FLC, substrate FBS was changed to sugar beet silage (SBS), which had a substantially lower buffering capacity than that of the FBS. With SBS, the FLC accomplished a stable fermentation at a pH level between 6.5 and 6.6, and a volatile fatty acid level (VFA) below 500 mg/L, but the FLC had to interact and to change the substrate dosage permanently. In a further experiment, the reactor temperature was increased from 41 to 50°C. Concomitantly, the specific GPR, pH and CH4 dropped down. Finally, the FLC automatically enabled a complete recovery in 16 days. Biotechnol. Bioeng. 2009; 102: 736,748. © 2008 Wiley Periodicals, Inc. [source] | ||||||||||||||||
