Conflicting perspectives in a housing association
Authors: Kjærbeck Susanne , Lundholt Marianne Wolff 
Published: July 2018

PurposeThe purpose of this paper is to investigate employees’ conflicting perspectives on the business strategy in a Danish housing association through a narrative approach, in order to gain insight into the relation between master- and counter-narratives. The authors discuss the possibility of integrating counter-narratives as a resource in strategy processes. Finally, the usefulness and challenges of the applied narrative approach are addressed.Design/methodology/approachThe study was undertaken as a case study of strategy communication in a private housing association. The empirical material consists of 16 qualitative interviews from all levels of the organization as well as recordings of meetings where management presents a new strategy to the employees. The study adopts a mixed methods interpretivist approach using focus groups and interviews as data and with a focus on narratives as sense-making resources. The applied method of analysis is based on narratology, sociological action analysis and the concept of “framing.”FindingsEmployees’ counter-narratives focus on practical problems regarding the implementation of the business strategy. They materialize through temporal structures and framing strategies through which employees’ perspectives are presented indirectly and with great care. In spite of their oppositional content, these counter-perspectives cannot be considered to be resistance; on the contrary, employees take great interest in solving the reported problems. Counter-narratives are seemingly useful resources in a form of “reality check” in the organization, in order to elucidate the implementation of the business strategy and make necessary adjustments. The research furthermore points to a more dialogical strategy communication where employees are involved earlier in the process rather than marginalized to “resistant bystanders.”Originality/valueThese findings give insight into the use of narratives as practical meaning construction in an organizational context, and in relation to strategy communication and change.
M&A effects on innovation and profitability in large European firms
Authors: Fernández Sara , Triguero Ángela , Alfaro-Cortés Esteban 
Published: July 2018

PurposeThe purpose of this paper is to explore the effects of mergers and acquisitions (M&As) on innovation and profitability in large European firms.Design/methodology/approachUsing information from a unique micro-longitudinal database of top European R&D investors and information from the European Commission (EC) Merger Control Authority, dynamic panel estimations with firm-level fixed effects are performed. Moreover, the paper presents a qualitative case study of a merger in the European electronic and electrical equipment industry.FindingsThe analysis of a sample of 562 M&As authorized by the EC Merger Control Authority shows that mergers positively influence the R&D intensity and profitability of top companies in the European Union over the period 2004–2012. Furthermore, empirical evidence shows that the timing and magnitude of these effects differs. In particular, the positive effect of mergers on R&D intensity is found for the short and large term while they influence profitability only in the large term.Originality/valueThis paper makes several contributions. First, unlike other studies on this topic, it investigates the effects of M&As using firm-level panel data on the top 1,000 European R&D companies instead of only examining a case study. Second, a unique data set has been used, which collects information on large European firms from the European Industrial R&D Investment Scoreboard and the EC antitrust authority. Finally, the paper accounts for the casual link between innovation effort and profitability when evaluating the potential effect of M&As on the R&D intensity and profitability of large European firms.
Local clientele: geography and comovement of stock returns
Authors: Uysal Vahap , Hoelscher Seth 
Published: July 2018

Purpose
Local investors have the ability to impact the stock prices and returns of local firms. However, the impact of news made by a firm on local investors and neighboring companies is absent from the academic literature. The purpose of this paper is to fill that void and examine how a local investor clientele affects the stock market reactions of firms located within the same geographic proximity as a news-generating firm.

Design/methodology/approach
After accounting for firm, industry, and geographic characteristics, this study examines how a firm’s dividend initiation announcement (positive news) influences stock prices of seemingly unrelated firms within the same metropolitan statistical area (MSA).

Findings
Dividend-paying firms located in areas with a higher percentage of dividend clientele experience a positive comovement reaction when a seemingly unrelated firm within the same MSA announces a dividend initiation. The positive reactions are specifically for dividend-paying firms, while non-dividend payers exhibit no significant response. These results are robust to numerous regression methods and alternative explanations.

Practical implications
These findings are consistent with the positive-investor-attention hypothesis, suggesting positive spillover effects from news announcements for other local firms in the presence of individual investor clientele.

Originality/value
This is the first study to link how news generated by one firm can influence other geographically local firms, providing evidence on the impact of individual investor clientele on stock returns of local non-news firms.
Artificial light at night causes top‐down and bottom‐up trophic effects on invertebrate populations
Authors: Bennie Jonathan , Davies Thomas W. , Cruse David , Inger Richard , Gaston Kevin J. 
Published: July 2018

Abstract

Globally, many ecosystems are exposed to artificial light at night. Nighttime lighting has direct biological impacts on species at all trophic levels. However, the effects of artificial light on biotic interactions remain, for the most part, to be determined.

We exposed experimental mesocosms containing combinations of grassland plants and invertebrate herbivores and predators to illumination at night over a 3‐year period to simulate conditions under different common forms of street lighting.

We demonstrate both top‐down (predation‐controlled) and bottom‐up (resource‐controlled) impacts of artificial light at night in grassland communities. The impacts on invertebrate herbivore abundance were wavelength‐dependent and mediated via other trophic levels.

White LED lighting decreased the abundance of a generalist herbivore mollusc by 55% in the presence of a visual predator, but not in its absence, while monochromatic amber light (with a peak wavelength similar to low‐pressure sodium lighting) decreased abundance of a specialist herbivore aphid (by 17%) by reducing the cover and flower abundance of its main food plant in the system. Artificial white light also significantly increased the food plant's foliar carbon to nitrogen ratio.

We conclude that exposure to artificial light at night can trigger ecological effects spanning trophic levels, and that the nature of such impacts depends on the wavelengths emitted by the lighting technology employed.

Policy implications. Our results confirm that artificial light at night, at illuminance levels similar to roadside vegetation, can have population effects mediated by both top‐down and bottom‐up effects on ecosystems. Given the increasing ubiquity of light pollution at night, these impacts may be widespread in the environment. These results underline the importance of minimizing ecosystem disruption by reducing light pollution in natural and seminatural ecosystems.
Digital health – a new medical cosmology? The case of 23andMe online genetic testing platform
Authors: Saukko Paula 
Published: July 2018

AbstractThis article argues that commercial digital health platforms and devices commodify participatory features of the digital creating a new medical cosmology. Drawing on sociology on medical cosmologies, research on digital media and marketing and an analysis of the 23andMe online genetic testing platform, I identify three features of this cosmology. First, digital health seeks to foment ‘flow’ or enjoyable, continuous immersion in health. Second, digital health configures its consumers as ‘co‐creators’ of health data and knowledge together with companies and other consumers. Third, digital health frames medical knowledge as tentative, up for revision and scepticism by expert and lay science. The way in which digital health configures consumers as immersed, creative and sceptical gives it an open‐ended and participatory air. However, the conceptual discussion and the analysis of the 23andMe platform highlight that these features represent commercial capture of the lifeworld, even if they appear radical against classical medical cosmologies.
Linking Consumers’ Food Choice Motives to their Preferences for Insect‐based Food Products: An Application of Integrated Choice and Latent Variable Model in an African Context
Authors: Alemu Mohammed H. , Olsen Søren B. 
Published: July 2018

AbstractConsumers’ attitudes, perceptions, personalities and motives play important roles in shaping their food choices. These factors are not fully observed by analysts, so they should be treated as latent variables. A number of economic studies treat such variables as direct measures of consumers’ food choice behaviour, even though this might introduce measurement error and endogeneity bias. We investigate the latent link between consumers’ preferences and food choice motives (FCMs) in an African context. We use an integrated choice and latent variable (ICLV) model specification for data analysis to recognise the latent nature of the FCMs and address the measurement and bias problems. The data originate from an incentivised discrete choice experiment conducted in Kenya to elicit consumers’ preferences for insect‐based foods. Our findings show that consumers’ preferences and choices are influenced by their latent motivational orientation. The results illustrate the benefit of the ICLV approach in accounting for consumers’ latent preference constructs in food choice and valuation research.
Comparative histomorphological and ultrastructural study of the luminal epithelium of the isthmus in laying and moulting domestic fowls (Gallus domesticus)
Authors: Mpango Mike M. , Madekurozwa Mary‐Cathrine 
Published: July 2018

AbstractThis study describes ciliated, nonciliated and mitochondrial luminal epithelial cells of the isthmus in laying and moulting domestic fowls using histological and ultrastructural techniques. The ciliated cells were nonsecretory, while numerous electron‐dense secretory granules were present in the nonciliated cells of laying birds. Mitochondrial cells, occurring in two morphologically distinct forms, constituted the third type of epithelial cell present in the isthmus. The SEM study showed that the luminal epithelium was dominated by ciliated cells, the cilia of which partially obscured adjacent nonciliated cells. The involution of the luminal epithelium in moulting birds occurred via autophagy, apoptosis and necrosis. Autophagic inclusions, which included autophagosomes and autolysosomes, were present in the early degenerative phases of ciliated, nonciliated and mitochondrial cells. Nonciliated cells underwent degeneration via apoptosis, which was characterized by nuclear and cytoplasmic condensation. Apoptotic and necrotic ciliated cells were evident during the intermediate and advanced stages of regression. The presence of apoptotic cell death was confirmed using the TUNEL assay. Loss of cilia via the formation of cilia packets was observed using TEM and SEM. Necrotic cell death occurred in mitochondrial cells during the intermediate and late stages of degeneration. In conclusion, the findings of the study on isthmus involution in moulting birds suggest that autophagy is a process confined to the early stages of degeneration, while apoptosis and/or necrosis occur in the terminal stages of regression.

Published: July 2018

AbstractAimThis study evaluated if oral supplementation with the probiotic bacterium Lactobacillus reuteri DSM 17938 improved enteral feeding tolerance and growth rates in extremely low birthweight (ELBW) infants.MethodA randomised, double‐blind, placebo‐controlled trial comprising 134 ELBW (<1000 g) infants born before gestational week 28 + 0. Daily supplementation of L. reuteri (1.25 × 108 bacteria/day) or placebo started within 3 days and continued until gestational week 36 + 0. Primary outcome was feeding tolerance and secondary outcome growth rate calculated as z‐score development.ResultsFeeding tolerance was similar in the probiotic and placebo group. Time to full enteral feeds was 15 days in both groups. The z‐score of the head circumference decreased in both groups from birth to day 28 of life, but it decreased less in the L. reuteri group compared to the placebo group: −1.2 SD (95% CI: −1.4 to −1.0) versus −1.7 SD (95% CI: −2.0 to −1.5; p = 0.001). Other growth parameters were similar in the study groups.ConclusionLactobacillus reuteri did not reduce time to reach full enteral feeds in ELBW infants. The L. reuteri supplemented infants, however, had a better growth rate of the head during the first month of life.
Intestinal macrophages and their interaction with the enteric nervous system in health and inflammatory bowel disease
Authors: Meroni Elisa , Stakenborg Nathalie , Viola Maria Francesca , Boeckxstaens Guy E. 
Published: July 2018

AbstractOver the past decades, there has been an increasing understanding of cellular and molecular mechanisms that mediate modulation of the immune system by the autonomic nervous system. The discovery that vagal nerve stimulation (VNS) attenuates endotoxin‐induced experimental sepsis paved the way for further studies investigating neuro‐immune interaction. In particular, great attention is now given to intestinal macrophages: several studies report the existence of both intrinsic and extrinsic neural mechanisms by which intestinal immune homoeostasis can be regulated in different layers of the intestine, mainly by affecting macrophage activation through neurotransmitter release. Given the important role of inflammation in numerous disease processes, such as inflammatory bowel disease (IBD), cholinergic anti‐inflammatory mechanisms are under intense investigation both from a basic and clinical science perspective in immune‐mediated diseases such as IBD. This review discusses recent insights on the cross‐talk between enteric neurons and the immune system, especially focusing on macrophages, and provides an overview of basic and translational aspects of the cholinergic anti‐inflammatory response as therapeutic alternative to reinstall immune homoeostasis in intestinal chronic inflammation.

Published: July 2018

AbstractAimTo explore the feasibility of the electronic assessment of potentially inappropriate medication (PIM) criteria in a large administrative database and to explore the validity of the cardiovascular subset of PIM criteria, by studying the association with relevant outcome.MethodA cohort study using administrative data from Stockholm County, Sweden (VAL database). Eligible for inclusion were community‐dwelling older people (≥65 years), alive in Stockholm County on 31 December 2015. We applied PIM criteria pertaining to the cardiovascular medication group (first‐level ATC C group), and we assessed the association between PIM use and mortality and hospitalisation.ResultsPatients’ (n = 315 120) mean age was 74.0 years (range 65‐114), and 54.7% were women. There were 111 cardiovascular PIM criteria in the repository, from which 44 were not registered or prescribed in our population. We excluded another 43 requiring information not available in the database, or duplicates, resulting in 24 applicable criteria. The prevalence of polypharmacy (≥ five medications) was 25.5% and the prevalence of at least one PIM use was 8.3%, including 2.8% underuse and 5.3% misuse. Patients with intake of ≥10 medications had 38% increased mortality risk compared to those with 0‐4 medications. Unplanned hospitalisation and emergency department visits were positively associated with underuse (12% and 25%, respectively) and misuse (13% and 12%, respectively).ConclusionIt was feasible to select a subset of cardiovascular PIM criteria originating from different PIM lists and to apply this subset in an administrative database. Additionally, by applying this subset, we showed significant associations with clinical outcome.
Brief group‐based acceptance and commitment therapy for stroke survivors
Authors: Majumdar Sarah , Morris Reg 
Published: July 2018

ObjectivesTo date, the efficacy of acceptance and commitment therapy (ACT) for stroke survivors has not been established. The aim of this study was to evaluate the efficacy of group‐based ACT for stroke survivors in comparison with treatment as usual (TAU) controls.MethodsFifty‐three participants were randomly assigned either to group‐based ACT (ACTivate Your Life after Stroke) or to a TAU control group (60% male; mean age: 63 years). The ACT intervention consisted of four weekly 2‐hr didactic group sessions. Therapeutic effects were measured by examining changes in depression (primary outcome), anxiety, hope, health‐related quality of life, self‐rated health status, and mental well‐being. Measures were completed at pre‐treatment, post‐treatment, and 2‐month follow‐up. A mixed‐design repeated‐measures multivariate ANOVA was conducted to analyse the findings.ResultsAnalysis based on intention to treat found that compared to participants in the TAU control, group‐based ACT significantly reduced depression and increased self‐rated health status and hopefulness in stroke survivors, with medium effect sizes. Significantly more participants reached clinically significant change of depression in the ACT intervention in comparison with the control group.ConclusionsThe results correspond with previous studies of group‐based ACT with other long‐term conditions. The findings from this current study suggest group‐based ACT may have promising utility and could offer a suitable low‐intensity psychological intervention for stroke survivors. However, further large‐scale research is required.Practitioner points

Acceptance and commitment therapy (ACT), delivered didactically to groups of stroke survivors, proved feasible and acceptable.

ACT had benefits, relative to treatment as usual, for depression, health status, and hope.

Several secondary outcome variables did not show dependable benefit for ACT: anxiety; health‐related quality of life; and mental well‐being.

Results should be treated as preliminary as the sample size was small, blinding was not possible, concomitant treatments were not monitored, and there was no attention control condition.

Despite these limitations, group‐based ACT merits further study as a potentially effective intervention.

SummaryBackgroundAllergic rhinitis (AR) management has changed in recent years following the switch from the concept of disease severity to the concept of disease control, publication of the AR clinical decision support system (CDSS) and development of mobile health (m‐health) tools for patients (eg Allergy Diary). The Allergy Diary Companion app for healthcare providers is currently being developed and will be launched in 2018. It incorporates the AR CDSS to provide evidence‐based treatment recommendations, linking all key stakeholders in AR management.ObjectiveTo produce an electronic version of the AR CDSS (e‐CDSS) for incorporation into the Allergy Diary Companion, to describe the app interfaces used to collect information necessary to inform the e‐CDSS and to summarize some key features of the Allergy Diary Companion.MethodsThe steps involved in producing the e‐CDSS and incorporating it into the Allergy Diary Companion were (a) generation of treatment management scenarios; (b) expert consensus on treatment recommendations; (c) generation of electronic decisional algorithms to describe all AR CDSS scenarios; (d) digitization of these algorithms to form the e‐CDSS; and (e) embedding the e‐CDSS into the app to permit easy user e‐CDSS interfacing.ResultsKey experts in the AR field agreed on the AR CDSS approach to AR management and on specific treatment recommendations provided by Allergy Diary Companion. Based on this consensus, decision processes were developed and programmed into the Allergy Diary Companion using Titanium Appcelerator (JavaScript) for IOS tablets. To our knowledge, this is the first time the development of any m‐health tool has been described in this transparent and detailed way, providing confidence, not only in the app, but also in the provided management recommendations.ConclusionThe Allergy Diary Companion for providers provides guideline and expert‐endorsed AR management recommendations.
