Neural representations of aversive value encoding in pain catastrophizers
Authors: Brown Christopher A. , Almarzouki Abeer F. , Brown Richard J. , Jones Anthony K. P. 
Published: March 2018

AbstractChronic pain is exacerbated by maladaptive cognition such as pain catastrophizing (PC). Biomarkers of PC mechanisms may aid precision medicine for chronic pain. Here, we investigate EEG biomarkers using mass univariate and multivariate (machine learning) approaches. We test theoretical notions that PC results from a combination of augmented aversive-value encoding (“magnification”) and persistent expectations of pain (“rumination”). Healthy individuals with high or low levels of PC underwent an experimental pain model involving nociceptive laser stimuli preceded by cues predicting forthcoming pain intensity. Analysis of EEG acquired during the cue and laser stimulation provided event-related potentials (ERPs) identifying spatially and temporally-extended neural representations associated with pain catastrophizing. Specifically, differential neural responses to cues predicting high vs. low intensity pain (i.e. aversive value encoding) were larger in the high PC group, largely originating from mid-cingulate and superior parietal cortex. Multivariate spatiotemporal EEG patterns evoked from cues with high aversive value selectively and significantly differentiated the high PC from low PC group (64.6% classification accuracy). Regression analyses revealed that neural patterns classifying groups could be partially predicted (R2 = 28%) from those neural patterns classifying the aversive value of cues. In contrast, behavioural and EEG analyses did not provide evidence that PC modifies more persistent effects of prior expectation on pain perception and nociceptive responses. These findings support the hypothesis of magnification of aversive value encoding but not persistent expression of expectation in pain catastrophizers. Multivariate patterns of aversive value encoding provide promising biomarkers of maladaptive cognitive responses to chronic pain that have future potential for psychological treatment development and clinical stratification.
Aneuploidy promotes intestinal dysplasia in Drosophila
Authors: Resende Luís Pedro , Monteiro Augusta , Brás Rita , Lopes Tatiana , Sunkel Claudio E. 
Published: March 2018

AbstractAneuploidy is associated with different human diseases, particularly cancer, but how different cell types within tissues respond to aneuploidy is not fully understood. In some studies, aneuploidy has been shown to have a deleterious effect and lead to cell death, however it has also been shown to be a causal event of tumorigenesis in other contexts.Here, we show that Drosophila intestinal stem cells have a particular tolerance to aneuploidy and do not activate apoptosis in response to chromosome misegregation like other non-stem cells. Instead, we observe the development of tissue dysplasia characterized by an accumulation of progenitor cells, increased stem cell proliferation rate, and an excess of cells of the enteroendocrine lineage. Our findings highlight the importance of mechanisms acting to prevent aneuploidy within tissue stem cells and provide an in vivo model of how these cells can act as reservoirs for genomic alterations that can lead to dysplasia.
Stages and trigger factors in the development of academic spin-offs
Authors: Parmentola Adele , Ferretti Marco 
Published: March 2018

PurposeThe purpose of this paper is to combine studies that describe the spin-off creation process with studies that analyze spin-off determinants to understand the phenomenon of spin-off development.Design/methodology/approachThis paper proposes a theoretical framework to improve our understanding of academic spin-off development in southern Italy. Following a systematic combining approach, the framework is constructed by iteratively matching the concepts derived by the literature on spin-off processes and spin-off determinants with the empirical findings obtained through a case study of 19 spin-offs in southern Italy.FindingsThe combination of empirical results and literature analysis helps us to identify a general model for spin-off creation that could be particularly useful to explain the criticalities of their development.Research limitations/implicationsThis paper provides implications for policy-makers in southern Italy regarding factors for which intervention would support the creation of new spin-offs. This study also provides useful implications for policy-makers in other contexts, such as areas that may or may not be at a disadvantage.Originality/valueThe resulting framework represents an original contribution to the literature because it: links two aspects – the stages of spin-off creation and determinants of spin-off development – which are often considered separately in existing studies; explores factors that either impede or facilitate the different stages of spin-off development; provides a series of findings that can be successively tested in other studies; and sheds more light on the context of southern Italy, which has been investigated in only a limited number of previous studies.
Inconsistency in intertemporal choice: a behavioral approach
Authors: González Fernández Isabel , Cruz Rambaud Salvador 
Published: March 2018

Purpose
The purpose of this paper is to introduce the main measures of inconsistency in the context of intertemporal choice and to identify the relationships between them (more specifically, the measures by Prelec, Takahashi and Rohde). In effect, Thaler (1981), awarded the Nobel Prize in Economics 2017, argued that when a preference must be expressed between two reward options, some people may reverse their original preference when a significant delay is introduced before the reward is to be received. This anomaly is known as inconsistency in intertemporal choice.

Design/methodology/approach
After a revision of the existing literature and by using the methods from mathematical calculus, the authors have derived the logical relationships between the measures presented in this paper.

Findings
The main contribution of this paper is the proposal of a novel parameter, the so-defined ratio of two instantaneous discount rates, which the authors call the instantaneous variation rate, which allows relating some other measures of inconsistency, namely the measures described by Prelec and Rohde. A limitation of this paper is the unavailability of empirical information about the inconsistency measures needed to substantiate the theoretical findings. Indeed, this paper has social implications because recent behavioral and neuroeconomic studies have shown the existence of preference reversal or time inconsistency in other areas. The authors’ models can be implemented in these fields in order to better analyze the situations of inconsistency.

Originality/value
The originality of this paper lies in the authors’ aim to bring some order to the proposed measures of inconsistency which have arisen as a result of the different approaches adopted.
Entrepreneurial orientation and sustainability initiatives in family firms
Authors: Mullens Drake 
Published: March 2018

Purpose
This paper aims to examine the relationship between family firm generation, performance and entrepreneurial orientation (EO) in investments in sustainability initiatives. The objective of this research is to establish EO as an important antecedent of investments in sustainability initiatives, assess EO’s interaction with firm performance and establish that later-generation family firms are more environmentally and socially responsible.

Design/methodology/approach
Data were collected in-person from 151 top managers in automobile and motorcycle dealerships in the southwestern USA. Regression analysis was utilized to analyze the hypothesized relationships.

Findings
EO is significantly and positively related to investments in sustainability initiatives. That relationship is dependent on the performance of the firm. At low levels of EO, high-performing firms invest significantly more in sustainability initiatives. However, at high levels of EO, low-performing firms invest slightly more in sustainability initiatives. The generation of the family business is moderately related to sustainability investments, with later-generation family firms investing more.

Originality/value
The findings herein bridge the gap between the entrepreneurship and sustainability literature by establishing EO as an important antecedent of corporate responsibility. Further, the results indicate that firm mechanisms such as EO are more important than the performance of the firm or slack resources available.
Service robots: value co-creation and co-destruction in elderly care networks
Authors: Čaić Martina , Odekerken-Schröder Gaby , Mahr Dominik 
Published: March 2018

PurposeThe purpose of this paper is to investigate the potential roles for service robots (i.e. socially assistive robots) in value networks of elderly care. Taking an elderly person’s perspective, it defines robot roles according to their value co-creating/destroying potential for the elderly user (i.e. focal actor), while acknowledging consequences for a network of users around the elderly (i.e. network actors).Design/methodology/approachThis qualitative, interpretative study employs in-depth phenomenographic interviews, supported by generative cards activities (i.e. Contextual Value Network Mapping), to elicit an elderly person’s tacit knowledge and anticipate the effects of introducing an automated actor on institutionalized value co-creation practices.FindingsThe proposed typology identifies six roles of socially assistive robots in an elderly person’s value network (enabler, intruder, ally, replacement, extended self, and deactivator) and links them to three health-supporting functions by robots: safeguarding, social contact, and cognitive support.Research limitations/implicationsElderly people have notable expectations about the inclusion of a socially assistive robot as a new actor in their value networks. The identified robot roles inform service scholars and managers about both the value co-destruction potential that needs to be avoided through careful designs and the value co-creation potential that should be leveraged.Originality/valueUsing network-conscious phenomenographic interviews before the introduction of a novel value proposition sheds new light on the shifting value co-creation interplay among value network actors (i.e. elderly people, formal and informal caregivers). The value co-creation/destruction potential of socially assistive robots and their corresponding roles in care-based value networks offer insights for the design of meaningful robotic technology and its introduction into the existing service networks.
The Fakegate scandal
Authors: Olson Erik L. 
Published: March 2018

PurposeAlthough ethics are frequently debated within the social marketing literature, there has been very little empirical study of deliberate ethical transgressions in promoting a good cause. The current study therefore aims to contribute by examining public reaction to the Fakegate scandal involving a climate scientist’s use of ethically questionable tactics in the “selling” of the anthropogenic global warming (AGW) cause.Design/methodology/approachContent analysis catalogues the Fakegate justifications and criticisms used by eight UK and US print media editorials and 1,010 associated reader comments.FindingsAmong the argument classification categories, the most common Fakegate justifications rely on a utilitarian “greater good” ethics perspective, while the most frequent criticisms rely on a normative “violation of rules” ethics perspective. AGW believers represent nearly all the scandal justifiers, while AGW skeptics and a substantial minority of AGW believers represent the critics.Research limitations/implicationsContent material is limited to only the Fakegate case and people with enough interest to contribute a relevant comment, although the expressed viewpoints may be more widely representative because they are generally consistent with findings from the AGW public opinion polls.Originality/valueThis study provides an understanding of the ethical dilemma that social marketers face when assigned a “difficult-to-sell” good cause. The findings of the widespread public skepticism toward the AGW cause suggest that social marketers should resist the temptation of using ethically questionable tactics in such difficult cases. Unfortunately, honest and effective AGW “selling” may be impossible until current technology and policy tradeoffs are reduced.
When service failure leads to sin
Authors: Chong Yit Sean , Ahmed Pervaiz K. 
Published: March 2018

Purpose
The purpose of this paper is to examine the notion of “service transgression” which violates customers’ religious beliefs through observing certain dietary guidelines that shape their religious identity. While service transgression and customer forgiveness are predominantly examined using experimental procedures or questionnaire survey in existing studies, this study adopts an interpretive paradigm to explore the complexities and idiosyncratic narratives of individual perceptions.

Design/methodology/approach
Detailed narrative accounts of 15 participants consisting of five Muslims, five Buddhists and five Hindus; who are working adults residing in Malaysia were gathered via in-depth interviews. Critical incident technique was employed with interpretive approach being undertaken to uncover key themes that form the essence of experiences in service transgressions.

Findings
The responses from participants were mainly contingent to the individuals’ interpretations of their religious expectations in the assessment of the incidents. Observations from the interview protocols reveal common themes in the consideration of whether one has indeed transgressed against the religious norms, the assignment of blame and responsibility and reparation of relationships. From the findings of this study, the authors developed a typology of conflict framing categories: “damaged identity”, “identity at risk” and “identity preservation” by considering both dyadic and triadic service relationships in service failure incidents which involve a violation of customers’ religious belief systems.

Practical implications
The outcome of this study seeks to inform service providers on the impact of service transgression of this nature upon consumers particularly in a multi-faith society. Additionally, this study provides insights into the implementation of service recovery strategies if and when such situation arises.

Originality/value
By undertaking a narrative enquiry, this study uncovers personal sense making in this phenomenon within the contextual frame of societal and historical norms. The outcome of this study provides insights to service providers on the impact of service transgression upon consumers particularly in a multi-faith context such as Malaysia. Additionally, this study discusses managerial implications associated with the implementation of service recovery strategies if and when such situation arises.
Recovery heroes from the past: Charles Dickens (1859:2003): “it was the best of times it was the worst of times”
Authors: Longworth Gail , Carson Jerome 
Published: March 2018

Purpose
The purpose of this paper is to provide a profile of the novelist Charles Dickens.

Design/methodology/approach
Several biographies and articles about the life of Charles Dickens were examined, to see if there was evidence that he experienced mental health problems.

Findings
While Dickens has been acclaimed for his ability to authentically portray the living conditions of the poor in the nineteenth-century Britain, there is comparatively little historical record of the fact that he may have experienced bipolar disorder. This paper suggests that he displayed many of the characteristic symptoms of bipolar.

Research limitations/implications
The story of Dickens’ own childhood is an amazing example of personal resilience. It no doubt enhanced the quality of his writing, but it may also have “sown the seeds” of a later mental illness.

Practical implications
So much attention has been focused on the colourful characters from Dickens’ novels, but little on the problems of the man himself.

Social implications
The story of Charles Dickens is as fascinating as any of the fictional characters he created, if not even more intriguing. His story confirms the link between writers, creativity and mood disorders.

Originality/value
Given the huge attention and worldwide acclaim paid to the books of Charles Dickens, which have inspired numerous films as well as musicals, it is surprising how little attention has been paid to the author himself and his struggles with mental illness.
Pets, animal-assisted therapy and social inclusion
Authors: Holttum Sue 
Published: March 2018

Purpose
Humans have close relationships with animals for companionship and in working roles. The purpose of this paper is to discuss recent papers on pets and dog-assisted interventions, and relates their findings to social inclusion.

Design/methodology/approach
A search was carried out for recent papers on pets, animal-assisted therapy and social inclusion/exclusion.

Findings
One paper discusses theories (often lacking in studies of animal-assisted therapy) of why animals may be good for human health and development. A recent review shows evidence that family pet ownership may aid children’s well-being, learning and social development, but too few studies have followed children over time in pet and non-pet households. Studies of dog-assisted interventions show stress-reduction, which in turn may explain why therapy for mental health in young people and adults was more effective with a dog than without. Social inclusion is hinted at but not measured directly, yet dog-assisted therapy might be helpful in this regard.

Originality/value
All the papers discussed in detail here represent up-to-date understanding in this area of knowledge. Benefits of human-animal bonds, especially with dogs, appear to be well-supported by biological as well as observational and self-report evidence. More research is needed on how much these attachments may assist social relating and relationships with other people, and social inclusion.
The effectiveness of support groups: a literature review
Authors: Worrall Hugh , Schweizer Richard , Marks Ellen , Yuan Lin , Lloyd Chris , Ramjan Rob 
Published: March 2018

PurposeSupport groups are a common feature of the mental health support engaged by carers and consumers. The purpose of this paper is to update and consolidate the knowledge and the evidence for the effectiveness of mental health support groups.Design/methodology/approachThis paper is based on a systematic literature review of relevant databases around support groups for mental health. Support groups are defined as meetings of people with similar experiences, such as those defined as carers of a person living with a mental illness or a person living with a mental illness. These meetings aim to provide support and companionship to one another.FindingsThe results show that there is a consistent pattern of evidence, over a long period of time, which confirms the effectiveness of mental health support groups for carers and people living with mental illness. There is strong, scientifically rigorous evidence which shows the effectiveness of professionally facilitated, family-led support groups, psychoeducation carers support groups, and professionally facilitated, program-based support groups for people living with mental illness.Research limitations/implicationsThis research implies the use of support groups is an important adjunct to the support of carers and people with mental illness, including severe mental illness.Originality/valueThis research brings together a range of studies indicating the usefulness of support groups as an adjunct to mental health therapy.
The role of marketing capabilities, absorptive capacity, and innovation performance
Authors: da Costa Juliana Conceição Noschang , Camargo Shirlei Miranda , Machado Toaldo Ana Maria , Didonet Simone Regina 
Published: March 2018

PurposeThe purpose of this paper is to analyze effects of absorptive capacity (ACAP) on organizational performance. The model looks at the mediating influence of marketing capabilities (innovative capability and new product development capability (NPDC)) and innovation performance (IP).Design/methodology/approachThis study takes a quantitative approach by using survey data from 333 Brazilian manufacturer managers involved with strategic marketing processes. Structural equation modeling was used to test the theoretical hypotheses.FindingsResults indicate that ACAP does not have a direct impact on organizational performance. The relation is fully mediated by marketing capabilities (innovative capability and NPDC) and IP.Research limitations/implicationsAccording to the research findings, managers should put efforts in the ACAP as well as marketing capabilities that will result in better organizational performance. This research is limited to the context of manufacturer firms in Brazil. However, it is suggested that an application of this research can be conducted in different industries and different countries.Originality/valueThis study contributes to theory and management practice. First, no study has explored all these constructs together. Through the relationship between ACAP and performance, the authors found that marketing capabilities and IP can fully mediate the former proposed relation. The authors’ contribution is the understanding of the role of ACAP influence on performance. Managers should be encouraged to invest in companies’ ACAP as well as marketing capabilities to differentiate themselves from competitors and improve performance.
