Co‐creating value in sponsorship relations: the case of the Royal Swedish Opera
Authors: Lund Ragnar 
Published: March 2010

PurposeInfluenced by emerging developments in service management, the aim of this paper is to develop a model for value co‐creation in sponsorship relations, with specific emphasis on inter‐organizational learning dimensions.Design/methodology/approachThe paper is longitudinal and based on data from the Royal Swedish Opera and relationships between the Opera and three sponsors. The paper combines participant observation with interviews during a three year period. It is inspired by theory from many areas, in particular from relationship and network thinking and the current development of new theories on service and value.FindingsThe findings are structured in a model of the development of a new sponsorship programme. The partners learnt by interacting with each other and the surrounding network. Value of sponsorship programmes increased with the number of non‐competing sponsors. Learning supported long‐term relations and enhanced the value of a sponsorship programme for new sponsors.Research limitations/implicationsThe paper introduces new service perspectives on sponsorship and contributes to the sponsorship literature with insights on inter‐organizational learning. The paper offers a rich in‐depth analysis of relational and network mechanisms and could be further developed in other sponsorship cases.Practical implicationsRelationships between commercial companies and cultural organizations often fail due to lack of knowledge on both sides. The paper suggests that a learning orientation is supportive to value co‐creation in sponsorship.Originality/valueSystematic integration of resources based on knowledge in networks is an important theme in the new service literature. This is the first major paper that simultaneously applies key concepts from relationship marketing, many‐to‐many networks and service‐dominant logic on sponsorship.

PurposeThe purpose of this paper is to deal with the issue of market redefinition through an examination of a unique industry that has met with multiple obstacles: online gambling. The main research question is how markets get redefined when quantum technological change occurs, despite the lack of formal support and a highly fragmented industry structure, typical in online industries.Design/methodology/approachThis industry lends itself to the analysis because of the intense competition for reconstruction of the field among state powers, professional associations, and global forces. The paper provides an archival and qualitative overview of the industry and identify the various forces competing for dominance in the market. It examines the competing logics in this industry and identify the sources and implications of such competition for emerging markets.FindingsBoth broad and specific contributions of this paper are discussed, namely the important role of professional and interest associations in industries without clear geographical boundaries, as well as the growing role for global moderating agencies.Research limitations/implicationsThe paper provides a timely example of the ways in which firms organize in the modern business environment. In addition, it discusses the volatile and complex power structure in a global economy. While the research is necessarily processual and does not provide for multiple settings, the extent of legal implications here can be generalized to much smaller differences in global markets.Originality/valueThis paper provides support for the idea that, contrary to many concepts of industry acceptance and growth, legitimacy is not a requisite condition for an industry to prosper.
Goal orientation and organizational commitment

Published: March 2010

PurposeThe purpose of this paper is to paper examine goal orientation and organizational commitment in relation to employees' job attitudes and performance in a hospital. Specifically, it investigates the effects of mastery and performance goals on different facets of organizational commitment and how these effects impact individuals' job outcomes.Design/methodology/approachThe paper utilized an online survey to collect data from 497 hospital employees. The conceptual model was tested using a three‐step mediation procedure of structural equation modeling with maximum likelihood estimation.FindingsThe results indicate that while mastery goal is related to the three components of organizational commitment, performance goal is only related to affective commitment. Although affective and normative commitment are both related to job satisfaction, only the former is linked to employees' performance.Research limitations/implicationsThe survey is conducted in an East Asian hospital. To ensure greater generalizability of the results, future research should be conducted using a broader Asian sample, preferably, in a different organizational setting, and using longitudinal methods in addition to online surveys.Practical implicationsWhen managing employees with Asian backgrounds, establishing mastery goal orientation can potentially cultivate higher organizational commitment. Managers may consider aligning affectively and normatively committed employees with more complex job assignments because these employees typically exhibit desirable job attitudes and innovative job performance.Originality/valueThe contributions are two‐fold: managerially and scholarly. Identifying employees' mindset in relation to goal orientation and commitment allows firms to effectively manage employees' performance. The paper also provides evidence for rethinking constructs' relevancy outside of North America.
Organizational sociotechnical diagnosis of managerial retention in an IT organization
Authors: Ghosh Koustab , Sahney Sangeeta 
Published: March 2010

PurposeTurnover of managerial employees at junior and middle levels has been widely recognized as a critical organizational concern. The problem happens to be more intensified for organizations belonging to the service sector as the services provided to client/customer groups get directly affected. A number of studies have shown that compensation factor alone does not explain the retention of managerial employees in the organization. This paper aims to focus on designing and balancing the organizational social and technical subsystems elements in order to moderate the turnover of junior and middle level managers in the company.Design/methodology/approachA number of selective junior and middle level managers were interviewed in‐depth and content analysis was made for categorization of level‐wise qualitative responses. The situation actor process‐learning action performance (SAP‐LAP) framework has been adopted as the diagnostic instrument of organizational analysis.FindingsThe findings from the paper shows that the organizational sociotechnical factors have an impact on managerial retention and the suggestive actions from the paper attempt to find solutions to the problem of managerial turnover faced by the company.Originality/valueThe SAP‐LAP framework as an instrument to the diagnosis of organizational sociotechnical system provides useful inputs to the management for future course of actions. Maintaining the balance between the social and technical subsystem factors is a critical prerequisite to managerial retention.
How well do food distributions predict spatial distributions of shorebirds with different degrees of self‐organization?
Authors: Folmer Eelke O. , Olff Han , Piersma Theunis 
Published: March 2010

Summary1. Habitat selection models usually assume that the spatial distributions of animals depend positively on the distributions of resources and negatively on interference. However, the presence of conspecifics at a given location also signals safety and the availability of resources. This may induce followers to select contiguous patches and causes animals to cluster. Resource availability, interference and attraction therefore jointly lead to self‐organized patterns in foraging animals.2. We analyse the distribution of foraging shorebirds at landscape level on the basis of a resource‐based model to establish, albeit indirectly, the importance of conspecific attraction and interference.3. At 23 intertidal sites with a mean area of 170 ha spread out over the Dutch Wadden Sea, the spatial distribution of six abundant shorebird species was determined. The location of individuals and groups was mapped using a simple method based on projective geometry, enabling fast mapping of low‐tide foraging shorebird distributions. We analysed the suitability of these 23 sites in terms of food availability and travel distances to high tide roosts.4. We introduce an interference sensitivity scale which maps interference as a function of inter‐individual distance. We thus obtain interference‐insensitive species, which are only sensitive to interference at short inter‐individual distances (and may thus pack densely) and interference‐sensitive species which interfere over greater inter‐individual distances (and thus form sparse flocks).5. We found that interference‐insensitive species like red knot (Calidris canutus) and dunlins (Calidris alpina) are more clustered than predicted by the spatial distribution of their food resources. This suggests that these species follow each other when selecting foraging patches. In contrast, curlew (Numenius arquata) and grey plover (Pluvialis squatarola), known to be sensitive to interference, form sparse flocks. Hence, resource‐based models have better predictive power for interference‐sensitive species than for interference‐insensitive species.6. It follows from our analysis that monitoring programmes, habitat selection models and statistical analyses should also consider the mechanisms of self‐organization.
Root herbivores and detritivores shape above‐ground multitrophic assemblage through plant‐mediated effects
Authors: Megías Adela González , Müller Caroline 
Published: March 2010

Summary 1. Indirect effects mediated by changes in plant traits are the main mechanism by which above‐ and below‐ground herbivores affect each other and their enemies. Only recently the role of decomposers in the regulation of such plant‐based systems has been considered. We hypothesized that: (i) below‐ground organisms, both herbivores (negative effect on plants) and detritivores (positive effect on plants), will have a profound effect on the interactions among above‐ground arthropods; (ii) floral herbivores will negatively affect other above‐ground herbivores associated with the plant; and (iii) not only above‐ and below‐ground herbivores, but also detritivores will affect the production of secondary metabolites, i.e. glucosinolates, in the plants. 2. We manipulated the presence of above‐ground herbivores, below‐ground herbivores and below‐ground detritivores on the Brassicaceae Moricandia moricandioides in the field to disentangle their individual and combined effects on other organism groups. We also investigated their effects on the plant’s chemical defence to evaluate potential mechanisms. 3. Our results show that not only above‐ and below‐ground herbivores, but also detritivores affected other herbivores and parasitoids associated with the host plant. Most effects were not additive because their strength changed when other organisms belonging to different functional groups or food web compartments were present. Moreover, below‐ground herbivore and detritivore effects on above‐ground fauna were related to changes in glucosinolate concentrations and in quantity of resources. 4. This study indicates that multitrophic interactions in plant‐based food webs can dramatically change by the action of below‐ground organisms. One of the most important and novel results is that detritivores induced changes in plant metabolites, modifying the quality and attractiveness of plants to herbivores and parasitoids under field conditions.

ChantreGR, SabbatiniMR & OrioliGA (2010). An after‐ripening thermal‐time model forLithospermum arvenseseeds based on changes in population hydrotime parameters.Weed Research50, 218–227.SummaryLithospermum arvenseseeds show primary physiological dormancy. Changes in population hydrotime parameters during after‐ripening were used to model primary dormancy loss.Lithospermum arvenseseeds were dry‐stored at constant temperatures of 5, 15, 24 and 30°C for 180 days. After different storage periods, seeds were incubated at 10°C at a range of water potentials (0 to −1.2 MPa). Experimentally obtained cumulative–germination curves were analysed by repeated probit regressions to obtain seed population hydrotime parameters. The population mean base water potential (Ψb(50)) showed a progressive decrease as after‐ripening time progressed and the dormancy release rate was positively related to storage temperature. The hydrotime constant (θH) and the SD of the base water potential (σΨb) were unaffected by after‐ripening time or storage temperature. To account for the effect of after‐ripening time and temperature on dormancy release, an after‐ripening thermal‐time model was developed. The model consisted of the description ofΨb(50) changes as a function of an after‐ripening thermal‐time index (θAT). An exponential decay function accurately described (R2 = 0.92) the decrease pattern ofΨb(50) as function ofθAT. Model evaluation under fluctuating soil water regimes showed a good correlation between observed and predicted data (r = 0.94 and 0.96). This indicated that the after‐ripening process could be adequately described as a thermal‐time response, further suggesting the potential applicability of the model to predictL. arvenseemergence in the field.

Fernández‐Aparicio M, García‐Garrido JM, Ocampo JA & Rubiales D (2010). Colonisation of field pea roots by arbuscular mycorrhizal fungi reduces Orobanche and Phelipanche species seed germination. Weed Research50, 262–268.SummaryPea (Pisum sativum) is an important grain legume crop whose cultivation in the Mediterranean basin and West Asia is severely constrained by infection by the weedy root parasite Orobanche crenata (crenate broomrape). Pea is a false host of other species such as O. minor, O. foetida and Phelipanche aegyptiaca. In the present experiments, we demonstrate that seed germination of the Orobanche and Phelipanche species examined is reduced in the presence of root exudates from pea plants colonised by arbuscular mycorrhizal (AM) fungi, Glomus mosseae and G. intraradices. Reduced germination was due to the effect of the AM fungi and not to the microbial populations potentially present in the soil inoculum. This protective effect of mycorrhizae was noticeable after 35 days of AM colonisation for O. crenata, O. foetida and P. aegyptiaca, but at least 45 days of colonisation were needed to get some reduction of O. minor germination.

Kurokawa S, Kobayashi H & Ikeda K (2010). Genetic background of an invasive Lolium population in central Japan using chloroplast DNA and SSR markers. Weed Research50, 245–252.SummaryTo determine the genetic background of an invasive population of Lolium spp., we compared three non‐coding regions of chloroplast DNA (cpDNA) and nine SSR loci of the population with those of 30 cultivars of Lolium multiflorum, Lolium perenne or their hybrid and two accessions of Lolium rigidum. For the cultivars and L. rigidum, bulked DNA was used for all analyses, due to variations within cultivars. Two of three regions in cpDNA were polymorphic among samples, generating four haplotypes (A–D). We found haplotypes A and B in L. multiflorum and L. rigidum, and haplotypes C and D only in L. perenne. All 48 individuals of the invasive population were discriminated as haplotype A, suggesting annual maternal origin. Nine loci of SSR generated 55 alleles in total in the invasive population. The presence or absence of these 55 alleles was counted for the bulked DNA of cultivars and L. rigidum. There were significant differences among species in the correspondences of alleles with those of the invasive populations. The correspondence of alleles with L. multiflorum was significantly higher than that with L. perenne or L. rigidum. These results suggested that the genetic background of the invasive population was very close to L. multiflorum. Although common traits among cultivars genetically close to the invasive population were not found, the wide variation in allele correspondence among L. multiflorum cultivars may indicate that non‐invasive cultivar breeding may be possible in the future.

CasagrandeM, MakowskiD, JeuffroyM‐H, Valantin‐MorisonM & DavidC (2010). The benefits of using quantile regression for analysing the effect of weeds on organic winter wheat.Weed Research50, 199–208.SummaryIn organic farming, weeds are one of the threats that limit crop yield. An early prediction of weed effect on yield loss and the size of late weed populations could help farmers and advisors to improve weed management. Numerous studies predicting the effect of weeds on yield have already been conducted, but the level of uncertainty about weed effect is expected to be very high in organic crops. It is thus more appropriate to provide farmers and advisors with distributions of possible production levels, rather than with point values. The purpose of this study was to estimate the effect of early weed density at the end of the tillering stage of organic winter wheat on subsequent yield and on late weed density at flowering, by using quantile regression. Results showed that this method can be applied to a hyperbolic model and to an allometric density‐dependent model, to describe the distribution of yield values and of late weed density respectively, as functions of early weed density measurements. Mechanical weed control showed no significant effect on the relationship between early weed density and grain yield, but it decreased late weed density. Yield and late weed density distributions derived by quantile regression provided sound information on the possible effect of weeds on organic winter wheat production.

Wang T, Shi Y, Li Y, Song Y & Darmency H (2010). Population growth rate of Setaria viridis in the absence of herbicide: resulting yield loss in foxtail millet Setaria italica. Weed Research50, 228–234.Summary Setaria viridis (green foxtail) is a common weed and is the putative ancestor of foxtail millet (Setaria italica). Population densities of S. viridis and its effect on foxtail millet yield were studied for 4 years in two locations, with three cultivars, under monoculture and no use of selective herbicide. Each year the density of S. viridis plants increased in all fields at a population growth rate λ = 1.13. The stability of the λ estimate in monoculture could serve as a reference value to predict the fate of a weed population in multi‐year demographic models, using corrective factors to account for specific effects of given crop rotation and cropping practices. The low λ value was due to a very low reproduction rate, around 6 10−4 adults per seed, which suggests high dormancy and seed predation. The yield of millet decreased linearly as the infestation increased, with the same slope whatever the cultivars. The yield loss was 0.58 tonne ha−1 for each additional plant m−2, indicating high sensitivity to competition from the wild relative. The close relationship between the weed and the crop, which could lead to similar biological responses to environmental conditions, could explain these results.

Slater EP, Langer P, Niemczyk E, Strauch K, Butler J, Habbe N, Neoptolemos JP, Greenhalf W, Bartsch DK. PALB2 mutations in European pancreatic cancer families.Recently, PALB2 was reported to be a new pancreatic cancer susceptibility gene as determined by exomic sequencing, as truncating PALB2 mutations were identified in 3 of 96 American patients with familial pancreatic cancer (FPC). Representing the European Registry of Hereditary Pancreatitis and Familial Pancreatic Cancer (EUROPAC) and the German National Case Collection for Familial Pancreatic Cancer (FaPaCa), we evaluated whether truncating mutations could also be detected in European FPC families. We have directly sequenced the 13 exons of the PALB2 gene in affected index patients of 81 FPC families. An index patient was defined as the first medically identified patient, stimulating investigation of other members of the family to discover a possible genetic factor. None of these patients carried a BRCA2 mutation. We identified three (3.7%) truncating PALB2 mutations, each producing different stop codons: R414X, 508‐9delAG and 3116delA. Interestingly, each of these three families also had a history of breast cancer. Therefore, PALB2 mutations might be causative for FPC in a small subset of European families, especially in those with an additional occurrence of breast cancer.
