Theorizing with managers: how to achieve both academic rigor and practical relevance?
Authors: Nenonen Suvi , Brodie Roderick J. , Storbacka Kaj , Peters Linda D. 
Published: May 2017

PurposeThe aim of the paper is to address the widening theory-praxis gap in marketing. The authors propose that one viable solution to this challenge is involving practitioners in research processes as active, reflective and empowered participants. Most extant discussions addressing the inclusion of managers as partners in theorizing restrain themselves to an “if” question, arguing whether or not it is possible to create sufficiently rigorous knowledge in collaboration with practitioners. This leaves the “how” question unanswered, i.e. how should such gap-bridging research be conducted in practice.Design/methodology/approachBased on a literature review of collaborative theorizing processes, the authors develop a conceptual framework highlighting the main research design decisions when theorizing with managers. The use of the framework is illustrated with four research program examples.FindingsMost accounts of theorizing with managers use – explicitly or implicitly – abduction as the main mode of inference. In addition to this philosophical commonality, our literature review identified 12 themes that should be considered when designing collaborative research processes. The four illustrative examples indicate that theorizing with managers is an effective way of producing and socializing both academically sound and managerially relevant knowledge. On the other hand, collaborative theorizing processes are time-consuming and studies using abductive reasoning may be more challenging to publish in top-tier journals.Originality/valueThis paper makes two contributions. First, the authors go beyond the extensive academic literature which provides a plethora of explanations and ideas for potential remedies for bridging the theory-praxis gap by offering a detailed description how one particular solution, theorizing with managers, unfolds in practice. Second, the authors ground collaborative theorizing processes in the philosophy of science and put abduction forward as a common nominator for such studies.
Theorizing with managers to bridge the theory-praxis gap
Authors: Brodie Roderick J. , Nenonen Suvi , Peters Linda D. , Storbacka Kaj 
Published: May 2017

Purpose
The purpose of this paper is to refine an agenda concerning the theory–praxis gap to develop a foundation for a research tradition.

Design/methodology/approach
The paper synthesizes and builds on the suggestions in commentary articles by Kohli (2017), Leeflang (2017) and Möller (2017).

Findings
The authors develop a research agenda consisting of the following issues: the need for a systemic view of business practice; the need for innovative and meaningful theoretical understanding; the need to identify conditions and approaches for collaborative theorizing; to further define and instruct the abductive approach; and to explore pragmatic realism to ensure both practical outcomes and truthful theories.

Originality/value
These five issues are a step towards developing a theory–praxis research tradition.
Systematic response errors in self-reported category buying frequencies
Authors: Ludwichowska Gosia , Romaniuk Jenni , Nenycz-Thiel Magda 
Published: May 2017

PurposeDespite the growing availability of scanner-panel data, surveys remain the most common and inexpensive method of gathering marketing metrics. The purpose of this paper is to explore the size, direction and correction of response errors in retrospective reports of category buying.Design/methodology/approachSelf-reported purchase frequency data were validated using British household panel records and the negative binomial distribution (NBD) in six packaged goods categories. The log likelihood theory and the fit of the NBD model were used to test an approach to adjusting the errors post-data collection.FindingsThe authors found variations in systematic response errors according to buyer type. Specifically, lighter buyers tend to forward telescope their buying episodes. Heavier buyers tend either to over-use a rate-based estimation of once-a-month buying and over-report purchases at multiples of six or to use round numbers. These errors lead to overestimates of penetration and average purchase frequency. Adjusting the aggregate data for the NBD, however, improves the accuracy of these metrics.Practical implicationsIn light of the importance of purchase data for decision making, the authors describe the inaccuracy problem in frequency reports and offer practical suggestions regarding the correction of survey data.Originality/valueTwo novel contributions are offered here: an investigation of errors in different buyer groups and use of the NBD in survey accuracy research.
Does unit pricing influence store price image dimensions and shopping intentions for retail stores?
Authors: Roth Stefan , Himbert Lena , Zielke Stephan 
Published: May 2017

Purpose
While previous literature focusses on the impact of unit pricing on the customer level by analysing customer awareness and product choice, the present research aims to highlight the impact unit pricing has at the store level.

Design/methodology/approach
The impact of unit pricing on the store price image is investigated in two experiments. While the first experiment assesses the general influence of unit price presence and unit price prominence on store price image, the second experiment provides further insights into the influence of unit price prominence on store price image and shopping intentions under consideration of moderating variables.

Findings
This research demonstrates that the availability of unit prices influences several store price image dimensions positively, namely, price processibility, price perceptibility and evaluation certainty. There is also an indirect positive effect on value-for-money perception. Furthermore, unit price prominence has a positive effect on the dimension price processibility. There is a positive influence of unit price presence and unit price prominence on the consumers’ intention to shop at a given store through the store price image.

Originality/value
This paper adds to the existing unit price and store price image literature and derives implications for retailers as well as for policymakers regarding the presentation of unit prices on price labels. Policymakers can use the results for motivating retailers to use unit price information more actively and present it more prominently beyond the minimum regulatory standards.
The role of geographical distance and its efficacy on global purchasing practices
Authors: Wiengarten Frank , Ambrose Eamonn 
Published: May 2017

PurposeThe purpose of this paper is to investigate the extent to which the geographical location of and thus the geographical distance between buyer and supplier impact on the efficacy of purchasing practices (i.e. strategic purchasing management, tactical purchasing management, relational purchasing management) in terms of operational performance.Design/methodology/approachThe authors utilise cross-country data collected through the International Purchasing Survey group across a variety of countries and industry sectors. The authors conduct exploratory factor analysis to assess construct validity and regression analysis to test the varying effects of purchasing practices on operational performance. The authors split the sample to compare potential differences in the efficacy of purchasing practices between buyers and suppliers through geographical characteristics.FindingsThe results indicate that the efficacy of purchasing practices does indeed vary depending on differences in geographical location. Specifically, the authors identify that in cases where the buyer and supplier are located in the same country tactical and relational purchasing tools have a positive impact on operational performance. However, in cases where they are situated in different countries none of the purchasing tools seems to significantly improve operational performance.Originality/valueResearch that has taken a cross-country perspective on the efficacy of supply chain practices is surprisingly sparse. Since most supply chains are becoming more and more global it is important to consider the geographical location of the supply chain members when assessing the performance benefits of supply chain practices such as purchasing tools. Thus, the authors introduce and test the concept of geographical distance on the efficacy of purchasing practices at the dyadic level. To test the implications of geographical distance for purchasing practices the authors use a large-scale cross-country survey.
The complex link between forgiveness, PTSD symptoms and well-being in female victims of intimate partner stalking
Authors: Baldry Anna Costanza , Cinquegrana Vincenza , Regalia Camillo , Crapolicchio Eleonora 
Published: May 2017

Purpose
The purpose of this paper is to examine the relationship between posttraumatic stress disorder (PTSD) symptoms and poor general health reported by female victims of intimate partner stalking (IPS) and victims’ forgiveness or lack of forgiveness towards their perpetrators, controlling for escalation of stalking, age of victims and dispositional forgiveness.

Design/methodology/approach
A total of 120 Italian female victims of IPS, who had obtained an administrative protective order (PO) issued by police in stalking cases (Ammonimento), took part in a retrospective study that examined the relationship between the presence or absence of victims’ forgiveness of perpetrators and victims’ PTSD symptoms and general well-being. Interviews took place after one, two or three years following the PO.

Findings
All participants reported some level of direct or indirect stalking, and up to 98 per cent had suffered both. In half of all cases, a PO had been breached within a year of its issuance. Positive forgiveness was not associated with lower PTSD symptoms and was marginally associated with well-being. Negative forgiveness (e.g. holding a grudge, desiring revenge) was associated with greater PTSD symptoms; holding a grudge was significantly associated with poorer general health.

Research limitations/implications
Victims of IPS experience a state of fear and anxiety due to the constant risk of being attacked, followed and controlled. Compared to studies about the protective role of forgiveness in community couples, this study found that among couples where stalking is present not only positive forgiveness does not take place at the same rate, but it is also not associated with the increased well-being. On the contrary, lack of forgiveness by stalked victims was related to PTSD symptoms and poorer health. Harbouring negative feelings, such a desire for revenge and holding a grudge towards a perpetrator, worsened woman’s mental health. These findings are novel and may assist the criminal justice system, law enforcement and service providers in their efforts to help women who are victims of IPS.

Originality/value
This study addresses the relationship between forgiveness and lack of forgiveness among victims of IPS and PTSD symptoms and victims’ poor health. Although longitudinal studies are needed to establish any causal relationship between stalking and mental health and the possibly mediating effects of forgiveness, this study is a first contribution to this important field of inquiry.
Citation personal display
Authors: Li Xingchen , Wu Qiang , Zhang Nan 
Published: May 2017

PurposeThe purpose of this paper is to investigate the extent to which researchers display citation information and examine whether there are researcher differences in citation personal display at the level of university, country, and academic rank.Design/methodology/approachPhysicists from 11 well-known universities in USA, Britain, and China were chosen as the subjects of the study. It was manually identified if physicists had mentioned citation counts, citation-based indices, or a link to Google Scholar Citations on the personal websites. Aχ2test is constructed to test researcher differences in citation personal display.FindingsResults showed that the overall proportion of citation personal display is not high (14.8 percent), with 129 of 870 physicists displaying citation. Moreover, physicists from different well-known universities indeed had a significant difference in citation personal display. Moreover, at the national level, it was noticed that physicists in well-known Chinese universities had the highest level of citation personal display, followed by Britain and the USA. Furthermore, this study also found that researchers who had the academic rank of professor had the highest citation personal display. In addition, the differences inh-index personal display by university, country, or academic rank were analyzed, and the results showed that they were not statistically significant.Originality/valueThis is the first study to investigate how widely researchers provide citation-based information on personal websites.
Parasites structuring ecological communities: The mistletoe footprint in Mediterranean pine forests
Authors: Mellado Ana , Zamora Regino 
Published: May 2017

Abstract

The capacity of parasitic plants in structuring natural communities is increasingly recognized. These plants can affect the structure, composition and productivity of plant communities by modifying the competitive balance between hosts and non‐host species and by altering the quantity and quality of resources entering the soil. Despite the progress made in this field, there is still a lack of integrative studies showing the structuring capacity of parasitic plants in forest ecosystems, where their effect may be less detectable due to the long life span of the system.

In this study we evaluate the long‐term impact of Viscum album subsp. austriacum on the woody‐plant community of a Mediterranean pineland. This mistletoe remains several years on the same host, exerting long‐lasting, spatially concentrated effects on community and ecosystem characteristics. Mistletoe concentrates zoochorous seeds and induces changes in the soil fertility and light availability beneath the canopy of parasitized trees, which have the potential to facilitate zoochorous–plant colonization, recruitment, and growth at the same time as it weakens the host. Here, we analyse whether mistletoe‐driven changes could result in a nucleus of zoochorous woody plants nourished by the abundant organic detritus accumulated under the host. We also analyse whether mistletoe effects can expand after host death.

We selected unparasitized, parasitized, and dead parasitized Pinus nigra trees, in which we studied the joint effect of mistletoe‐mediated changes in soil nutrient and light availability, with the seed rain, seed predation, seedling establishment, plant recruitment, and plant growth. Light‐ and soil‐nutrient resources were greater under parasitized trees, and intensified after host death. The seed rain was maximum under parasitized trees, where seedling recruitment proved more likely. Sapling density, richness, and growth increased with the development of parasitism.

Our findings show that V. album exerts a strong and lasting impact on the structure and dynamics of Mediterranean pinelands, with parasitized trees acting as centres for the establishment and growth of colonizing fleshy‐fruited woody species, which, over the long term, promote vegetation shifts by limiting dominant pine trees and facilitating less represented fleshy‐fruited shrubs.

Asymmetric winter warming advanced plant phenology to a greater extent than symmetric warming in an alpine meadow
Authors: Suonan Ji , Classen Aimée T. , Zhang Zhenhua , He Jin‐Sheng 
Published: May 2017

Abstract

The warming of terrestrial high‐latitude ecosystems, while increasing, will likely be asymmetric across seasons—where winter non‐growing seasons will warm more than summer‐growing seasons. Asymmetric winter warming in temperature‐sensitive ecosystems may delay spring phenological events by reducing the opportunity that a plants’ chilling requirement is met. Similarly, symmetric warming can advance spring phenology.

To explore the impact of asymmetric warming on plant phenology, we applied a year‐round warming and a winter warming treatment to our experimental plots. Over a 2‐year period, we monitored leaf‐out and flowering phenology for 11 plant species.

There was variation among species, however, both winter and year‐round warming, advanced the leaf‐out day and the first flowering day relative to the control treatment. Winter warming advanced leaf‐out and flowering phenology by 11.1 (±2.4) and 12.6 (±2.9) days respectively. However, year‐round warming had less of an impact advancing leaf‐out and flowering phenology by 5.1 (±2.1) and 10.0 (±3.0) days respectively.

Our study provides direct evidence that asymmetric winter warming has a larger impact on plant phenology than symmetric year‐round warming. Increasing soil temperature in the winter from below to above freezing temperatures advanced the spring phenology of alpine plants. Winter warming increased soil temperature more than year‐round warming, which explains why phenology advanced under winter warming more than under year‐round warming. In addition, early or mid‐season flowering plant species displayed different phenology strategies in warmer winters.

Relative to other ecosystems, alpine ecosystems such as the Tibetan Plateau will likely respond to asymmetric warming given the higher amplitude of winter temperature increases due to climatic warming. Our data indicate that seasonal variation in warming should be considered when predicting and modelling the response of alpine ecosystems to climatic change.

Individual and non‐additive effects of exotic sap‐feeders on root functional and mycorrhizal traits of a shared conifer host

AbstractForest pests drive tree mortality through disruption of functional traits linked to nutrient acquisition, growth and reproduction. The impacts of attack by individual or multiple above‐ground herbivores on root functional traits critical to tree health have received little attention. This is especially true for exotic herbivores, organisms often found in disturbed forests.We excavated whole‐root systems from eastern hemlock (Tsuga canadensis) individuals experimentally infested with hemlock woolly adelgid (HWA:Adelges tsugae) and elongate hemlock scale (EHS:Fiorina externa) individually, or in combination, for periods of 2 and 4 years. Below‐ground root biomass, functional traits and storage nutrients were measured to assess impacts of herbivory. We also quantified ectomycorrhizal fungal (EMF) colonisation of fine roots and used culture‐independent methods to examineEMFdiversity.Trees infested withHWAhad a greater root mass fraction (root to total biomass ratio), although feeding had no observable effects on root functional traits (e.g. specific root length) or on resource allocation to roots.HWAfeeding did significantly reduceEMFcolonisation of hemlock fine roots, though surprisingly,EMFdiversity and that of other fungal associates were unaffected. In contrast toHWA,EHS(alone or in conjunction withHWA) feeding had no observable effect on below‐ground traits orEMFcolonisation alone; however, its presence mediatedHWAeffects when trees were co‐infested. Simultaneous infestation within the same year yielded significant reductions inEMFcolonisation, whereas priorEHSattack weakenedHWAeffects.Our results collectively suggest that priorEHSattack dampens the impact ofHWAon below‐ground functional traits. This highlights how the timing and sequence of herbivore arrival can alter plant‐mediated interactions between herbivores and their effects on above–below‐ground linkages and associated tree health.Aplain language summaryis available for this article.
Estimating demographic contributions to effective population size in an age‐structured wild population experiencing environmental and demographic stochasticity
Authors: Trask Amanda E. , Bignal Eric M. , McCracken Davy I. , Piertney Stuart B. , Reid Jane M. 
Published: May 2017

Abstract

A population's effective size (Ne) is a key parameter that shapes rates of inbreeding and loss of genetic diversity, thereby influencing evolutionary processes and population viability. However, estimating Ne, and identifying key demographic mechanisms that underlie the Ne to census population size (N) ratio, remains challenging, especially for small populations with overlapping generations and substantial environmental and demographic stochasticity and hence dynamic age‐structure.

A sophisticated demographic method of estimating Ne/N, which uses Fisher's reproductive value to account for dynamic age‐structure, has been formulated. However, this method requires detailed individual‐ and population‐level data on sex‐ and age‐specific reproduction and survival, and has rarely been implemented.

Here, we use the reproductive value method and detailed demographic data to estimate Ne/N for a small and apparently isolated red‐billed chough (Pyrrhocorax pyrrhocorax) population of high conservation concern. We additionally calculated two single‐sample molecular genetic estimates of Ne to corroborate the demographic estimate and examine evidence for unobserved immigration and gene flow.

The demographic estimate of Ne/N was 0.21, reflecting a high total demographic variance () of 0.71. Females and males made similar overall contributions to . However, contributions varied among sex‐age classes, with greater contributions from 3 year‐old females than males, but greater contributions from ≥5 year‐old males than females.

The demographic estimate of Ne was ~30, suggesting that rates of increase of inbreeding and loss of genetic variation per generation will be relatively high. Molecular genetic estimates of Ne computed from linkage disequilibrium and approximate Bayesian computation were approximately 50 and 30, respectively, providing no evidence of substantial unobserved immigration which could bias demographic estimates of Ne.

Our analyses identify key sex‐age classes contributing to demographic variance and thus decreasing Ne/N in a small age‐structured population inhabiting a variable environment. They thereby demonstrate how assessments of Ne can incorporate stochastic sex‐ and age‐specific demography and elucidate key demographic processes affecting a population's evolutionary trajectory and viability. Furthermore, our analyses show that Ne for the focal chough population is critically small, implying that management to re‐establish genetic connectivity may be required to ensure population viability.
