The Role of Ambidexterity in Marketing Strategy Implementation: Resolving the Exploration-Exploitation Dilemma
Authors: Prange Christiane , Schlegelmilch Bodo B. 
Published: March 2014

AbstractFormulating consistent marketing strategies is a difficult task, but successfully implementing them is even more challenging. This is even more pertinent as marketing strategies quite often incorporate inherent conflicts between major breakthroughs and consolidation. Consequently, marketers need to balance exploratory and exploitative strategies. However, the literature lacks concrete insights for marketing managers as to how exploratory and exploitative strategies can be best combined. This paper addresses this issue by introducing a framework of multiple types of ambidexterity. Based on qualitative research, tools and procedures are identified to overcome marketing dilemmas and support strategy implementation by drawing on ambidextrous designs.
Investigating Research Streams of Conjoint Analysis: A Bibliometric Study
Authors: Teichert Thorsten , Shehu Edlira 
Published: March 2014

AbstractConjoint analysis (CA) is one of the most important methods for preference elicitation. In this paper we investigate the intellectual structure within the conjoint analytical research community. Analyses based on single papers provide a method-based overview of streams of conjoint research. By using novel bibliometric techniques in this field we complement findings of existing reviews. We use co-citation and factor analysis of the most cited articles in SSCI to identify the most important articles and research streams. Seven research streams are revealed which are visualized by means of multidimensional scaling. Tables and graphics reveal the disciplinary affiliations of contributors to CA, the special structure within the classes as well as links between them.
Metaheuristics for the Order Batching Problem in Manual Order Picking Systems
Authors: Henn Sebastian , Koch Sören , Doerner Karl F. , Strauss Christine , Wäscher Gerhard 
Published: March 2014

AbstractIn manual order picking systems, order pickers walk or drive through a distribution warehouse in order to collect items which are requested by (internal or external) customers. In order to perform these operations efficiently, it is usually required that customer orders are combined into (more substantial) picking orders of limited size. The Order Batching Problem considered in this paper deals with the question of how a given set of customer orders should be combined such that the total length of all tours is minimized which are necessary to collect all items. The authors introduce two metaheuristic approaches for the solution of this problem: the first one is based on Iterated Local Search; the second on Ant Colony Optimization. In a series of extensive numerical experiments, the newly developed approaches are benchmarked against classic solution methods. It is demonstrated that the proposed methods are not only superior to existing methods but provide solutions which may allow distribution warehouses to be operated significantly more efficiently.
Management Research on Reciprocity: A Review of the Literature
Authors: Göbel Markus , Vogel Rick , Weber Christiana 
Published: March 2014

AbstractAlthough reciprocity is fundamental to all social orders, management research offers few reviews of the concept’s theoretical origins and current applications. To help bridge this gap, we elucidate the dominant understandings of reciprocity, ask which areas of research emerge from them, and explore how they interconnect. Our bibliometric methodology detects four clusters of management research on reciprocity. Across these clusters, authors subscribe mainly to substantialist ontology, marginalize morally oriented motives consistent with relational ontology, and largely assume that benefit-oriented motives underlie reciprocity. We outline the advantages of a moral-oriented relationalist concept of reciprocity and discuss potential areas for its development in management research.
Improving Environmental Scanning Systems Using Bayesian Networks
Authors: Welter Simon , Mayer Jörg H. , Quick Reiner 
Published: March 2014

AbstractAs companies’ environment is becoming increasingly volatile, scanning systems gain in importance. We propose a hybrid process model for such systems’ information gathering and interpretation tasks that combines quantitative information derived from regression analyses and qualitative knowledge from expert interviews. For the latter, we apply Bayesian networks. We derive the need for such a hybrid process model from a literature review. We lay out our model to find a suitable set of business environment indicators to forecast a company’s key financials. Deriving lessons learned from a prototype in the industrial sector, we evaluate the utility of our model following the design science research paradigm. We find our model to especially convince in completeness, transparency and transportability when compared with “pure” mathematical models.

Published: March 2014

Study design Prospective study of surgical correction of thoracolumbar kyphotic deformity caused by ankylosing spondylitis. Objectives To assess surgical outcomes and complications of thoracolumbar kyphotic deformity corrected with transpedicular closing-wedge osteotomy performed in a regional hospital. Summary of background data There have been several studies reporting on the results of surgical correction of deformity in ankylosing spondylitis all over the world. However, there has not been any local data published. Methods From 2003 to 2011, we had performed 12 transpedicular closing-wedge osteotomies in 9 patients with ankylosing spondylitis for correction of kyphotic and scoliotic deformity in thoracolumbar spine. Operative outcomes were assessed clinically by recording the Japanese Orthopaedic Association (JOA) scores, visual analogue scale (VAS) pain scores, Oswestry Disability Index (ODI) preoperatively and postoperatively and patient satisfaction postoperatively. Radiological outcome was assessed by measuring thoracic kyphosis, lumbar lordosis and sagittal plumb line preoperatively and postoperatively as well as the degree of surgical correction. Occurrence of complications was recorded by our standard audit protocol. Results All patients had a single level of osteotomy done at a time. Most of the osteotomies were done at L2 or L3. The mean amount of correction was 21.6°. Complications included dural tear, pseudoarthrosis and transient radiculopathy. The extent of correction and incidence of complications improved with experience. Conclusion Despite transpedicular closing-wedge osteotomy being a major operation that is not without complications, most of our patients had good clinical results and subjective satisfaction.
Targeting the mitochondrial apoptotic pathway: a preferred approach in hematologic malignancies?
Authors: Brinkmann K , Kashkar H 
Published: March 2014

AbstractAcquired resistance toward apoptosis represents one of the hallmarks of human cancer and a major cause of the inefficacy of most anticancer treatment regimens. Based on its ability to inhibit apoptosis, the B-cell lymphoma/leukemia 2 (Bcl-2) protein family has garnered the most attention as a promising therapeutic target in cancer. Accordingly, efforts have lately been focused on the development of drugs targeting Bcl-2 proteins with considerable therapeutic success, particularly in hematologic malignancies. Here, we review the previous studies and highlight the pivotal role of the Bcl-2 protein family in the homeostasis of hematologic tissue compartment. This knowledge provides more insight into why some cancers are more sensitive to Bcl-2 targeting than others and will foster the clinical evaluation of Bcl-2-targeting strategies in cancer by avoiding severe on-target side effects in the development of healthy tissues.

Published: March 2014

Objective.To describe the implementation of a population-based surveillance system for multidrug-resistant gram-negative bacilli (MDR-GNB).Design.Population-based active surveillance by the Georgia Emerging Infections Program.Setting.Metropolitan Atlanta, starting November 2010.Patients.Residents with MDR-GNB isolated from urine or a normally sterile site culture.Methods.Surveillance was implemented in 3 phases: (1) surveying laboratory antibiotic susceptibility testing practices, (2) piloting surveillance to estimate the proportion of GNB that were MDR, and (3) maintaining ongoing active surveillance for carbapenem-nonsusceptible Enterobacteriaceae and Acinetobacter baumannii using the 2010 Clinical and Laboratory Standards Institute (CLSI) breakpoints. Pilot surveillance required developing and installing queries for GNB on the 3 types of automated testing instruments (ATIs), such as MicroScan, in Atlanta's clinical laboratories. Ongoing surveillance included establishing a process to extract data from ATIs consistently, review charts, manage data, and provide feedback to laboratories.Results.Output from laboratory information systems typically used for surveillance would not reliably capture the CLSI breakpoints, but queries developed for the 3 ATIs did. In November 2010, 0.9% of Enterobacteriaceae isolates and 35.7% of A. baumannii isolates from 21 laboratories were carbapenem nonsusceptible. Over a 5-month period, 82 Enterobacteriaceae and 59 A. baumannii were identified as carbapenem nonsusceptible.Conclusions.Directly querying ATIs, a novel method of active surveillance for MDR-GNB, proved to be a reliable, sustainable, and accurate method that required moderate initial investment and modest maintenance. Ongoing surveillance is critical to assess the burden of and changes in MDR-GNB to inform prevention efforts.

Objective.Determine the prevalence of extended-spectrum β-lactamase (ESBL)–producing Enterobacteriaceae (ESBL-PE) contamination of food and colonization of food handlers in a hospital kitchen and compare retrieved ESBL-PE strains with patient isolates.Design.Cross-sectional study.Setting.A 2,200-bed tertiary care university hospital in Switzerland.Participants.Food handlers.Methods.Raw and prepared food samples were obtained from the hospital kitchen, with a comparator group from local supermarkets. Fecal samples collected from food handlers and selectively pre-enriched homogenized food samples were inoculated onto selective chromogenic media. Phenotypic confirmation of ESBL production was performed using the double disk method. Representative ESBL-PE were characterized using polymerase chain reaction (PCR) and sequencing for blaCTX-M, blaSHV, and blaTEM genes, and Escherichia coli strains were typed using phylotyping, repetitive element palindromic PCR, and multilocus sequence typing. Meat samples were screened for antibiotic residues using liquid chromatography time-of-flight mass spectrometry.Results.Sixty (92%) of the raw chicken samples were ESBL-PE positive, including 30 (86%) of the hospital samples and all supermarket samples. No egg, beef, rabbit, or cooked chicken samples were ESBL-PE positive. No antibiotic residues were detected. Six (6.5%) of 93 food handlers were ESBL-PE carriers. ESBL-PE strains from chicken meat more commonly possessed blaCTX-M-1 and blaCTX-M-2, whereas blaCTX-M-14and blaCTX-M-15 were predominant among strains of human origin. There was partial overlap in the sequence type of E. coli strains of chicken and human origin. No E. coli ST131 strains or blaCTX-M-15 genes were isolated from meat.Conclusions.Although there is significant ESBL-PE contamination of delivered chicken meat, current preventive strategies minimize risks to food handlers, hospital staff, and patients.
Ecological importance of sharks and rays in a structural foodweb analysis in southern Brazil

Published: March 2014

AbstractUnderstanding the trophic interactions and the position of species within a foodweb is crucial if we want to understand the dynamics of marine communities and the impact individual components of the community have on trophic network compartments. Recent studies have indicated sharks and rays are important elements within foodwebs. In this study, we evaluated the ecological importance of sharks and rays in a subtropical ecosystem off the coast of southern Brazil by using topological analyses. We tested the hypotheses that some elasmobranchs can be considered key elements within the foodweb, and that large predators have topological importance (act as keystones), so that, when large predators are excluded, mesopredator elasmobranchs occupy higher topological positions. Our results indicate that Galeocerdo cuvier, Carcharhinus obscurus, Carcharias taurus, Sphyrna lewini and S. zygaena are species with large ecological function values and may exert a powerful influence over lower levels. These issues need to be considered by conservation and fishery management groups since it appears that ecosystem integrity may be compromised by reductions in the populations of large predators. Carcharhinus obscurus, S. zygaena and Zapteryx brevirostris were found to be the elasmobranchs with largest values of centrality, and can, therefore, be considered key elements in the topological structure.

Influence of resources on maintenance operations with different asset monitoring levels
Authors: A. Alabdulkarim Abdullah , D. Ball Peter , Tiwari Ashutosh 
Published: March 2014

Purpose
– The demand for contracts on assets availability has increased. Recently published papers show that the use of asset health monitoring technologies is being encouraged to improve the asset performance. This is based on reason rather than analysis. This paper aims to understand and assess the effect of different types of business processes for maintenance resource levels on the behaviour of the maintenance operations and asset availability located at different customer locations using different asset monitoring levels.

Design/methodology/approach
– A discrete event simulation (DES) model was developed to mimic complex maintenance operations with different monitoring levels (reactive, diagnostics, and prognostics). The model was created to understand and assess the influence of resources (labour and spare parts) on a particular maintenance operation. The model was created to represent different levels of asset monitoring to be applied in a case study. Subsequently, different levels of spare parts (ranging from deficient inventory to a plentiful spares inventory) and labour were applied to show the effects of those resources on the asset availability.

Findings
– This research has found that the DES was able to discern different processes for asset monitoring levels in complex maintenance operations. It also provided numerical evidence about applying such asset monitoring levels and proved that the higher asset monitoring level does not always guarantee higher asset availability.

Practical implications
– The developed model is a unique model that can provide the decision makers of maintenance operations with numerical evidence to select an appropriate asset monitoring level based on their particular maintenance operations.

Originality/value
– A novel DES model was developed to support maintenance operations decision makers in selecting the appropriate asset monitoring level for their particular operations. This unique approach provides numerical evidence rather than reasoning, and also proves that the higher asset monitoring level does not always guarantee higher asset availability.
The rules of global engagement for developing country firms
Authors: Ketkar Sonia 
Published: March 2014

Purpose– This study aims to examine how property rights, financial liberalization and the control of corruption at the country level influence the inward and outward global engagement of domestic firms from developing countries. The author also examines whether firms with certain resource endowments such as human capital or technological capabilities are better positioned to globalize as the aforementioned institutional factors evolve.Design/methodology/approach– Using a sample of 18,365 firms from 57 developing countries and multilevel modeling, the author shows that institutional factors are related to inward and outward global engagement.Findings– The author finds that firms with human capital are more likely to move outward in the presence of lower levels of corruption. Domestic firms possessing technological capabilities are more likely to engage inward as financial liberalization eases the access to capital.Originality/value– Many existing studies that have investigated the impact of institutional factors on internationalization by developing country firms have bundled different institutions together therefore sacrificing a focus on the effect of specific institutions on these firm decisions. While the author knows that institutions matter for developing country firm globalization, there is limited research on which institutions matter. There is also a debate on how institutions matter for developing country firms. The study sheds light on these aspects. The author also uses hierarchical linear modelling and uses both country- and firm-level variables.
Evaluating the role ofblatin finding graduate employment in post-Soviet Ukraine
Authors: Onoshchenko Olga , C. Williams Colin 
Published: March 2014

Purpose– This paper aims to evaluate the use of personal connections to circumvent formal procedures, known asblatin the Soviet era, in post-Soviet societies by studying its role in graduate employment recruitment.Design/methodology/approach– To do this, the extent to which and howblatis used by graduates to find a job in the city of Mykolayiv in Ukraine is analysed through 85 face-to-face structured interviews with those who in the past seven years have sought employment after graduating from university.Findings– The finding is thatblatis widely used by graduates to find a job. However, contrary to the existing literature which suggests thatblathas become commodified in post-Soviet market societies with monetary payment being requested by and given to personal connections “pulling strings”, no evidence is found that this is the case. Instead, this remains a non-monetised form of friendly help by and for close social relations, akin to the Soviet era, and is viewed in a positive or neutral manner by participants even though its consequences can be to circumvent meritocratic formal recruitment procedures and foster nepotism and cronyism.Research limitations/implications– This study ofblatis limited to analysing graduate recruitment in one city in Ukraine. Broader empirical research on the contemporary role ofblatin this and other spheres in post-Soviet societies and beyond is now required so as to develop a more nuanced context-bound understanding of both the positive and negative facets of this social practice in contemporary societies.Originality/value– This study reveals thatblatis commonly used to find graduate jobs and is widely viewed as a socially acceptable practice, despite hindering meritocratic recruitment procedures.
Exploring the impact of Investors in People
Authors: M. Smith Simon , Stokes Peter , F. Wilson John 
Published: March 2014

Purpose– Investors in People (IiP) is a UK government-backed scheme aimed at enabling organizations to develop their training and development cultures and, thereby, their competitiveness. The purpose of this paper is to examine the perceptions and understandings of individuals in six organizations undergoing IiP to explore recent claims within the literature concerning the Standard's impact on training and development, and job satisfaction.Design/methodology/approach– Data from 35 semi-structured interviews among managers and employees of six diverse organizations were gathered and analysed.Findings– The paper identifies three key findings in response to recent literature: first, the findings do not support a causal relationship between IiP and training and development; second, the findings do not support a causal relationship between IiP and job satisfaction; third, and to support the other findings, the results indicate little employee awareness of IiP.Practical implications– If IiP – UKCES are to realize the potential of their Standard, it needs to find a way to ensure it has a direct and positive impact on skill development.Originality/value– While much of the previous research has identified associations between IiP and various outcomes, this paper seeks to identify the extent to which these associations can be considered to be causal.
