Time‐of‐day services marketing
Authors: Dacko Scott G. 
Published: July 2012

PurposeThe purpose of this paper is to synthesize, organize, and discuss multidisciplinary research influential to a service firm's use of a cyclical time‐based marketing approach that may be aptly termed time‐of‐day services marketing, to introduce a general process and framework to assist in the evaluation of its strategic use, and to present areas in need of future research.Design/methodology/approachObjectives are achieved via conceptual analysis and a synthesis and organization of the relevant multidisciplinary literature.FindingsThe paper finds that the principal benefits to service firms of adopting a time‐of‐day services approach in varying degrees are that it is able to assist the firm in offering multiple, unique value‐propositions, providing superior contextual value to the customer, enhancing customer perceptions of value in relation to their needs, and supporting the firm's pursuit of a sustainable competitive advantage in its services.Practical implicationsTime‐of‐day services marketing is a viable approach for some firms but is not a strategy to be pursued by all firms. Service industry executives and managers should carefully weigh its adoption in terms of an overarching framework to identify the best services strategy for their marketing and business objectives.Originality/valueTime‐of‐day services marketing has received little strategic attention in the services marketing literature. Furthermore, there is no good, published source of guidance to help service industry executives and managers make decisions about the extent that such an approach may present opportunities for value creation and competitive advantage. This paper addresses these voids by providing and discussing a comprehensive set of multi‐disciplinary factors, process, and framework that facilitate its evaluation for strategic adoption. Theoretically, the research contributes to the body of services marketing knowledge by altering the services marketing view of the “day” to be one that can be increasingly examined as less‐constant in terms of many service‐relevant individual and social behaviors, more systematically varying, and increasingly explainable on biological/physiological, sociological and/or psychological bases which are ultimately highly relevant to services marketers
“Five Co‐s” in innovating: a practice‐based view
Authors: Russo‐Spena Tiziana , Mele Cristina 
Published: July 2012

PurposeThe purpose of this paper is to frame innovation as a process of co‐creation according to a practice‐based view.Design/methodology/approachThe paper focuses on the innovation practices that occurred within the web contexts of ten companies. In accordance with netnography research, data include preliminary studies of the web‐based context, naturalistic observations of the community and the activities of its members, and direct interactions with the members of the innovating community.FindingsThis work proposes the integration of innovation, practice and the emerging co‐creation research. The paper develops the five “Co‐s” model including: co‐ideation, co‐valuation, co‐design, co‐test and co‐launch. Each “Co‐“ represents a phase of the innovation process resulting from dynamic and on‐going interactions among resources, actions, and a group of actors who are interrelated via a dense network. Within each “Co‐“, the authors identify practices and elements of practices.Practical implicationsA firm's managers should influence co‐creation opportunities by contributing to script practices. These managers should be able to consider more clearly the full options of co‐creation activities and be involved in designing and responding to co‐creation initiatives. They should also understand that each phase could provide an opportunity for collaboration that enhances the value of co‐creation. In this manner, managers could orchestrate multiple resources (e.g., actors, actions tools and output language).Originality/valueThis work brings innovation into the realm of practice by moving the focus from the outcome to the process –, i.e. from innovation as a new artefact to the act of innovating. In this context, innovating is the system of on‐going co‐creation practices performed by people who merge knowledge, actions, tools, languages and artefacts to create something new and better. In this view, innovators are carriers of practices.
Organizational and occupational identification
Authors: Gümüş Murat , Hamarat Bahattin , Çolak Ertuğrul , Duran Erol 
Published: July 2012

PurposeThis paper aims to explore the effects of two work related identification (occupational and organizational) of school teachers on intention to early retirement (withdrawal) and satisfaction with the occupation and satisfaction with the school. It also seeks the influence of perceived external prestige on withdrawal and satisfaction.Design/methodology/approachAn empirical study was carried out at public schools in Canakkale, Turkey. Data collected from 238 teachers were analyzed. The correlations between identification and organizational prestige, desire for early retirement, and overall satisfaction of teachers were tested with several demographic variables such as age, gender, tenure and union membership. Ordinal logistic regression analysis (OLR) was conducted to reveal probabilistic behavior of response variables on the basis of explanatory variables.FindingsThe results show that both categories of identification have reverse effect on intention to early retirement, and both categories have positive effect on job satisfaction. Perceived external prestige has no effect on intention to early retirement and job satisfaction, but it increases satisfaction from the school. Finally, the “self” and the “occupation” were found salient categories for teachers' identification.Originality/valueIdentification literature has long been concentrated on organizational level identification. This paper explores the influence of both organizational and occupational categories of identification, comparatively. Being a teacher is seen as a prestigious occupation in Turkey. Findings about identity as a teacher also confirmed that “self” and “occupation” are two main identity references in the Turkish setting.
Self‐efficacy and workaholism as initiators of the job demands‐resources model
Authors: Guglielmi Dina , Simbula Silvia , Schaufeli Wilmar B. , Depolo Marco 
Published: July 2012

PurposeThis study aims to investigate school principals' well‐being by using the job demands‐resources (JD‐R) model as a theoretical framework. It aims at making a significant contribution to the development of this model by considering not only job demands and job resources, but also the role of personal resources and personal demands as predictors of work engagement and burnout. In particular, it was hypothesised that job demands may mediate the relationship between workaholism and burnout, whereas job resources may mediate the relationship between self‐efficacy and work engagement and burnout.Design/methodology/approachA survey study was conducted. In total, 224 school principals (67 percent women) during training activities completed a questionnaire.FindingsThe results of SEM analyses largely supported the hypotheses by showing that personal variables operate as initiators of health impairment and motivational processes.Research limitations/implicationsThe study lends support to the literature on individual resources that underlines the role that personal resources play in work engagement and burnout. It contributes to the JD‐R model by highlighting the role of personal demands (i.e. workaholism), which has an effect on the development of burnout in school principals.Practical implicationsThe implications of these findings for interventions aimed at the promotion of school principals' well‐being are discussed.Originality/valueThis study advances the understanding of the role played by personal resources and personal demands in the job demands‐resources model. The value added is represented by the study of workaholism as personal demand, which in turn influences job demands and also the health impairment it triggers.
Explaining M&A performance: a review of empirical research
Authors: Das Arindam , Kapil Sheeba 
Published: July 2012

PurposeThe purpose of this paper is to provide an understanding of different explanations in mergers and acquisitions (M&A) research that deal with M&A performance. After five decades of M&A research, the findings on M&A performance are diverse and sometimes inconsistent with each other. The explanatory variables studied in the empirical works reflect primarily on researchers’ approach, construct, measurement techniques and data availability, leading to inconsistencies among the findings. In order to understand how researchers have measured M&A performance so far, the gaps in existing work and to identify the scope of future work, the authors conduct a systematic review of empirical M&A research on explaining M&A performance.Design/methodology/approachThis research has been carried out as a structured assessment of past literature. The findings from selected research works have been categorized, grouped and summarized to discern a meta‐analytic view of the work carried out to date.FindingsThe M&A performance measures are diverse owing to heterogeneous views on what constitutes M&A performance and organization performance. They are categorized under Accounting Measures, Market Measures and Other Measures, including subjective assessments. The explanatory variables found in the studies are extensive and can be categorized under Deal Characteristics, Managerial Effects, Firm Characteristics and Environmental Factors.Originality/valueThe paper extracts some key trends in M&A performance studies carried out in empirical works over two decades. The findings help to identify drawbacks and set an agenda for future work.
Effects of disturbances on the carbon balance of tropical peat swamp forests

Published: July 2012

AbstractTropical peatlands have accumulated huge soil carbon over millennia. However, the carbon pool is presently disturbed on a large scale by land development and management, and consequently has become vulnerable. Peat degradation occurs most rapidly and massively in Indonesia, because of fires, drainage, and deforestation of swamp forests coexisting with tropical peat. Peat burning releases carbon dioxide (CO2) intensively but occasionally, whereas drainage increases CO2 emission steadily through the acceleration of aerobic peat decomposition. Therefore, tropical peatlands present the threat of switching from a carbon sink to a carbon source to the atmosphere. However, the ecosystem‐scale carbon exchange is still not known in tropical peatlands. A long‐term field experiment in Central Kalimantan, Indonesia showed that tropical peat ecosystems, including a relatively intact peat swamp forest with little drainage (UF), a drained swamp forest (DF), and a drained burnt swamp forest (DB), functioned as net carbon sources. Mean annual net ecosystem CO2 exchange (NEE) (± a standard deviation) for 4 years from July 2004 to July 2008 was 174 ± 203, 328 ± 204 and 499 ± 72 gC m−2 yr−1, respectively, for the UF, DF, and DB sites. The carbon emissions increased according to disturbance degrees. We found that the carbon balance of each ecosystem was chiefly controlled by groundwater level (GWL). The NEE showed a linear relationship with GWL on an annual basis. The relationships suggest that annual CO2 emissions increase by 79–238 gC m−2 every 0.1 m of GWL lowering probably because of the enhancement of oxidative peat decomposition. In addition, CO2 uptake by vegetation photosynthesis was reduced by shading due to dense smoke from peat fires ignited accidentally or for agricultural practices. Our results may indicate that tropical peatland ecosystems are no longer a carbon sink under the pressure of human activities.
Aggregate Fluctuations and the Cross-Sectional Dynamics of Firm Growth
Authors: Holly Sean , Petrella Ivan , Santoro Emiliano 
Published: July 2012

SummaryThe paper explores time variation in the distribution of firm level growth of total sales. Three novel results are reported. First, firms on the left-hand side of the distribution, i.e. firms that are growing more slowly or declining, are typically more responsive to aggregate shocks than those on the right-hand side of the distribution. Second, trending behaviour in the volatility of firm growth is predominantly driven by increasing dispersion in the growth of highly performing firms. Third, shifts in the probability mass on either side of the mode may act as important propagators of business fluctuations. Financial frictions emerge as a mechanism that is capable of accounting for these facts.

AbstractSubchronic morphine treatment induces P‐glycoprotein (P‐gp) up‐regulation at the blood–brain barrier. This study investigates the rate and extent to which P‐gp and breast cancer‐resistance protein (Bcrp) increase at the rat blood–brain barrier following subchronic morphine treatment. Rats were given increasing doses of morphine (10–40 mg/kg) or saline i.p. twice daily for 5 days. The brain cortex large vessels and microvessels were then mechanical isolated 6, 9, 12, 24, and 36 h after the last injection. The gene and protein expression of P‐gp and Bcrp in morphine‐treated and control rats were compared by qRT‐PCR and western blotting. The levels of Mdr1a and Bcrp mRNAs were not significantly modified 6 h post morphine, but the Mdr1a mRNA increased 1.4‐fold and Bcrp mRNA 2.4‐fold at 24 h. P‐gp and Bcrp protein expression in brain microvessels was unchanged 6 h post morphine and increased 1.5‐fold at 24 h. This effect was more pronounced in large vessels than in microvessels. However, extracellular morphine concentrations of 0.01–10 μM did not modify the expressions of the MDR1 and BCRP genes in hCMEC/D3 human endothelial brain cells in vitro. MK‐801 (NMDA antagonist) and meloxicam (cyclo‐oxygenase‐2 inhibitor) given after morphine treatment completely blocked P‐gp and Bcrp up‐regulation. Interestingly, misoprostol and iloprost, two well‐known agonists of prostaglandin E2 receptors induced both MDR1 and BCRP mRNA levels in hCMEC/D3. Thus, morphine does not directly stimulate P‐gp and Bcrp expression by the brain endothelium, but glutamate released during morphine withdrawal may do so by activating the NMDA/cyclo‐oxygenase‐2 cascade.

“The Midwifery Two‐Step”: A Study on Evidence‐Based Midwifery Practice
Authors: Kennedy Holly Powell , Doig Eleanor , Hackley Barbara , Leslie Mayri Sagady , Tillman Stephanie 
Published: July 2012

Introduction: To date, there has been little documentation of how practice‐based midwifery networks in the United States might influence the transfer and development of knowledge in childbearing and women's health care. The first phase of this participatory action research project was to conduct a qualitative study with a community of midwifery practices to understand their perspectives on evidence‐based practice and how an organized network could facilitate their work.Methods: Midwives within the community of interest were invited by letter or e‐mail to participate in individual or small group interviews about knowledge transfer, primary concerns of evidence‐based practice, and potential for a midwifery practice‐based research network. Participatory action research strategies and organizational ethnographic approaches to data collection were used to guide qualitative interviews.Results: Eight midwifery practices enrolled in the study with 23 midwives participating in interviews. They attended births at 2 hospitals in the community. Two broad areas of discourse about evidence‐based practice were identified: 1) challenges from influential persons, finances and resources, and the cultural perception of midwifery, and 2) strategies to foster best practice in the face of those challenges. The midwives believed a research network could be useful in learning collectively about their practices and in the support of their work.Discussion: Evidence‐based practice is a goal but also has many challenges in everyday implementation. Practice‐based research networks hold promise to support clinicians to examine the evidence and form strong coalitions to foster best clinical practice. The second phase of this study will work with this community of midwives to explore collective strategies to examine and improve practice.

Published: July 2012

AbstractRecent investigations conducted on several tritrophic systems have demonstrated that egg parasitoids, when searching for host eggs, may exploit plant synomones that have been induced as a consequence of host oviposition. In this article we show that, in a system characterized by host eggs embedded in the plant tissue, naïve females of the egg parasitoid Anagrus breviphragma Soyka (Hymenoptera: Mymaridae) responded in a Y‐tube olfactometer to volatiles from leaves of Carex riparia Curtis (Cyperaceae) containing eggs of one of its hosts, Cicadella viridis (L.) (Hemiptera: Cicadellidae). The wasp did not respond to host eggs or to clean leaves from non‐infested plants compared with clean air, whereas it showed a strong preference for the olfactometer arm containing volatiles of leaves with embedded host eggs, compared with the arm containing volatiles of leaves from a non‐infested plant or host eggs extracted from the plant. When the eggs were removed from an infested leaf, the parasitoid preference was observed only if eggs were added aside, suggesting a synergistic effect of a local plant synomone and an egg kairomone. The parasitoid also responded to clean leaves from an egg‐infested plant when compared with leaves from a non‐infested plant, indicating a systemic effect of volatile induction.

BackgroundCutaneous B‐cell lymphoproliferative lesions can pose diagnostic challenges. This study investigates the utlility of flow cytometry in 42 cases of suspected cutaneous B‐cell lymphoma.MethodsAll available cases were reviewed [World Health Organization‐European Organization for Research and Treatment of Cancer (WHO‐EORTC) classification]. Flow cytometry, immunohistochemistry and polymerase chain reaction‐immunoglobulin H (PCR‐IgH) analysis of blood and/or lesional skin were performed on primary cutaneous B‐cell lymphoma (pcBCL, 17 cases), secondary cutaneous BCL (scBCL, 8 cases) and atypical lymphoid hyperplasia (ALH, 17 cases).ResultsFlow cytometry of skin detected a B‐cell clone in 3/13 cases of ALH, 8/8 cases of pcBCL and 4/4 cases of scBCL, while PCR detected a clone in 3/14 cases of ALH, 4/15 cases of pcBCL and 6/8 cases of scBCL. Of eight cases of pcBCL analyzed by both methods, all eight were positive by flow while only three were positive by PCR. All cases positive by PCR were also positive by flow. Of five cases with both flow and light chain immunohistochemistry, all five showed light chain restriction by flow, while only two were positive by immunohistochemistry.ConclusionFlow cytometry is more sensitive than PCR in detecting B‐cell lymphoproliferative disorders (12/12 cases, 100% vs. 10/23 cases, 43%; p < 0.001). Furthermore, flow cytometry complements immunohistochemistry in the detection of light chain restriction.
Limit Load Solutions for Cracked Elbows Subjected to Internal Pressure and In-Plane Bending
Authors: Simha C. Hari Manoj 
Published: July 2012

AbstractIn this article, limit load solutions for cracked elbows containing through-wall and part through-wall axial and circumferential cracks under internal pressure and in-plane bending loading are presented. For elbows with axial cracks, limit pressure solutions are presented, and modifications to existing limit moment solutions are proposed. The foregoing limit pressure and limit moment solutions are used in conjunction with a novel interaction curve to obtain limit load solutions for elbows with axial cracks under combined pressure and moment loading. If the applied moment and pressure are within (outside) the envelope of the interaction curve, no failure (failure) is indicated. Furthermore, limit pressure and limit moment solutions for circumferentially cracked elbows are developed using the same interaction curve. Limit loads computed with the solutions presented in this work are compared with experimental results and the agreement is found to be within acceptable limits after accounting for the uncertainties in the experimental results.
