AbstractBackgroundMexico City has the highest aging rate in the country, as well as a high prevalence of diabetes mellitus (DM) and arterial hypertension (HT). All three on their own, are known to increase oxidative stress (OE).MethodsFinal groups included 18 patients without DM or HT (control group), 12 with DM, 23 with HT, and 18 with DM and HT. The EO was measured by the quantification of reactive oxygen species (ROS), and by determination of lipid peroxidation.ResultsHAS patients showed increased ROS levels as did men with HAS compared with the respective DM and HT groups. Also, women of the control group showed higher levels of ROS compared with men. HT in an aged population turned out to be the most influential factor for oxidative stress increase while DM had no effect whatsoever.
Functional Social Structure in Baboons: Modelling Interactions Between Social and Environmental Structure in Group-Level Foraging
Authors: Bonnell Tyler R. , Henzi S. Peter , Barrett Louise 
Published: February 2018

AbstractIn mobile social groups, cohesion is thought to be driven by patterns of attraction at both the individual and group level. In long-lived species with high group stability and repeated interactions, such as baboons, individual-to-individual attractions have the potential to play a large role in group cohesion and overall movement patterns. In previous work, we used GPS mapping of a group of baboons in De Hoop, Western Cape, South Africa, to demonstrate the influence of such attractions on movement patterns. We also demonstrated the existence of emergent group-level structures, which arose as a consequence of individual social influence. Specifically, we found a core-periphery structure, in which a subset of influential animals exerted an influence on each other and those animals in the periphery, while those in the periphery were influenced by the core but did not exert any influence over others. Here, we use agent-based modelling of baboon groups to investigate whether this group-level structure has any functional consequences for foraging behaviour. By varying individual level attractions, we produced baboon groups that contained influence structures that varied from more to less centralized. Our results suggest that varying centrality affects both the ability of the group to detect resource structure in the environment, as well as the ability of the group to exploit these resources. Our models predict that foraging groups with more centralized social structures will show a reduction in detection and an increase in exploitation of resources in their environment, and will produce more extreme foraging outcomes. More generally, our results highlight the link between social and environmental structure on functional outcomes for mobile social groups of animals.
Is the hedging efficiency of weather index insurance overrated? A farm-level analysis in regions with moderate natural conditions in Germany
Authors: Doms Juliane , Hirschauer Norbert , Marz Michael , Boettcher Falk 
Published: February 2018

Purpose
The purpose of this paper is to analyze the hedging efficiency (HE) of weather index insurances (WII) based on a whole-farm approach. The aim is to identify how different types of WII affect the economic performance risk of real farms in the light of the heterogeneity of farm operations and natural conditions.

Design/methodology/approach
Using historic simulation, the HE of various hedging strategies is computed for 20 farms in regions with moderate natural conditions. A priori defined “standardized” WII and hedge ratios as well as ex post “optimized” strategies are analyzed. The latter is identified through a risk programming approach that determines the strike level and hedge ratio that would have minimized the volatility of each farm’s historic total gross margins (TGMs) ex post.

Findings
(i) The correlations between the weather indexes and the yields of the farms’ main crop (wheat) do not provide useful insights regarding the whole-farm HE because farms’ performance risk is considerably affected by volatile factors other than wheat yield; (ii) Standardized WII are ill-suited to hedge performance risk for the majority of studied farms; (iii) A considerable positive whole-farm HE could have been obtained on average if farmers had been able to use the “optimized” risk management strategy. Using farm-specific information thus seems to be essential for identifying meaningful hedging strategies.

Originality/value
This study provides added value by analyzing the HE of WII for 20 German crop farms in “moderate” regions. The results show that exemplary tests of WII in extreme conditions provide no decision support for farmers in other regions.
Automated adaptive selling
Authors: Kaptein Maurits , McFarland Richard , Parvinen Petri 
Published: February 2018

PurposeThis paper aims to develop and test a method of automating, for online retailers, the practice of adaptive selling, which is typically used by salespeople in face-to-face interactions. This method customizes persuasive messages for individual customers as they navigate a retailer’s website.Design/methodology/approachThis paper demonstrates a method for the online implementation of automated adaptive selling using sales influence tactics. Automated adaptive selling is compared to nonadaptive selling in three e-commerce field studies.FindingsThe results reveal that adaptive selling is more effective than nonadaptive selling. The click-through rates increased significantly when adaptive selling was used.Research limitations/implicationsThis paper highlights the effectiveness of existing theories concerning adaptive human-to-human selling and their utility to online selling. The authors demonstrate the added value of adaptive selling in e-commerce, thereby opening up a novel area of research into adaptive selling online. While the paper focuses on the adjustment of sales influence tactics, other factors could be investigated for adjustment in future research (e.g. prices).Practical implicationsThe methods, described in detail, are readily available for implementation by online retailers. The implementations are timely and increasingly valuable as e-commerce expands into interpersonal channels (e.g. instant messengers and social media).Originality/valueTo the authors’ knowledge, this paper is the first to formally implement automated adaptive selling as described in the ISTEA model in an e-commerce setting.
What do Chinese consumers want? A value framework for luxury hotels in China
Authors: Wu Ben , Yang Wan 
Published: February 2018

Purpose
In the past decade, the luxury hotel industry in China has experienced rapid growth. To date, few scholars have investigated what consumers value about their experiences in luxury hotels generally, let alone specifically in the Chinese context. As a result, little is known about what Chinese consumers value in luxury hotel services. To bridge this gap, this paper aims to (1) develop a five-factor luxury hotel value framework from a value co-creation perspective; and (2) assess the relationship between these value dimensions and Chinese consumers’ intentions to stay in luxury hotels.

Design/methodology/approach
In total, 492 Chinese luxury hotels consumers participated in the study. A confirmatory factor analysis was used to validate the proposed measurement model, and a hierarchical linear regression was used to test the relationship between luxury hotel value and purchase intentions.

Findings
The authors assessed five dimensions of luxury hotel value in the current study: utilitarian value, symbolic value, hedonic value, relational value and financial value. The regression results indicate that for Chinese luxury consumers, hedonic value is the most important predictor of luxury hotel purchase intentions, followed by financial value and utilitarian value. Interestingly, symbolic value and relational value do not significantly influence Chinese consumers’ luxury hotel purchase intentions.

Practical implications
Luxury hoteliers in China can use the value framework when making decisions about market segmentation and brand positioning and to gain a deeper understanding of what motivates target consumers’ purchase intentions. They can also use such knowledge to tailor their product offerings to the preferences of target consumers.

Originality/value
The current study is the first empirical test of a luxury hotel value framework from a value co-creation perspective in the Chinese market. Taking Chinese luxury consumers’ unique characteristics into consideration, the authors further investigate the relationships between various dimensions of luxury hotel value and Chinese consumers’ purchase intentions.
Think twice before using door-in-the-face tactics in repeated negotiation
Authors: Wong Ricky S. , Howard Susan 
Published: February 2018

Purpose
The purpose of this paper is to examine the detrimental effects of the door-in-the-face (DITF) tactic in repeated negotiation. A more complete understanding of its negative consequences is essential to make an informed decision about its use.

Design/methodology/approach
This paper is the product of two between-subjects scenario-based negotiation experiments involving university students in Hong Kong (Study 1) and professionals in the UK with negotiation experience (Study 2).

Findings
Both the studies herein showed that detecting opponents using this tactic reduced the degree to which negotiators found their counterparts trustworthy. It also increased the likelihood of negotiators switching to an alternative partner in a collaborative project. This relationship is mediated by perceived trustworthiness. Negotiators who had detected opponents’ use of DITF made higher offers and obtained better outcomes in a subsequent negotiation. These findings indicate that negotiators who benefitted from DITF considered its use ethical, while those who suffered because of its use by others found it unethical.

Practical implications
Before using DITF, users should be wary of the likelihood they and their counterpart will negotiate again and/or will collaborate in a future project.

Originality/value
This paper presents a new perspective from which the use of DITF may backfire in a subsequent negotiation, in terms of both objective and subjective outcomes. This is, to the best of the authors’ knowledge, the first paper to address how user and victim judge the ethicality of DITF tactics. The findings offer a building block for future research on other compliance techniques in repeated negotiations.
Community’s knowledge need and knowledge sharing in Wikipedia
Authors: Pee L.G. 
Published: February 2018

PurposeIn practice, showing the community’s need for knowledge (e.g. listing requests for new articles) is used to drive knowledge sharing in Wikipedia. Yet, theoretical understanding of how it influences one’s knowledge sharing is still lacking. The aim of this study is to develop a model of the influence and show that one takes others’ utility into account (utility interdependence).Design/methodology/approachThe proposed model was tested with data collected in a survey of 323 Wikipedia users.FindingsOthers’ knowledge need affects one’s perceived forgone benefit of free riding (i.e. a cost of knowledge sharing) and, thereby, increases the intention to share knowledge.Originality/valueThis study contributes to research by identifying utility interdependence in knowledge sharing. For practice, the findings provide empirical support for the general belief that showing others’ knowledge need is useful for promoting sharing.

The impact of employees’ well-being on performance in the workplace
Authors: Haddon Janice 
Published: February 2018

Purpose
The purpose of this paper is to look at the link between employee well-being in the workplace and its effect on productivity. Specifically, it looks at the different types of well-being (physical, nutritional and mental) and how organisations should be putting the welfare of staff at the heart of their workplace culture, to ensure their well-being and productivity.

Design/methodology/approach
Written as a viewpoint, the paper outlines the ways in which organisations traditionally offer employees incentives to look after their physical and nutritional well-being, such as gym memberships and healthy food options. It goes on to look at the impact of mental health on productivity and the symptoms employees may display if they are suffering with mental illness.

Findings
Mental health is one of the key contributors to productivity, and employers should do more to ensure the mental well-being of their staff. In addition, it outlines the impact a person’s mental well-being can have not only on themselves, but also on those around them, affecting, therefore, the productivity of a team/organisation as a whole, not just the individual.

Originality/value
The findings in the paper are based on personal experience, as well as recent statistics which are used to highlight the importance of the arguments made in the paper about the effect of mental health on and individual’s well-being and productivity. It is designed to advise HR managers and employers of the steps they can take to ensure the well-being of their employees and the benefits to themselves in doing so.
Crossing power and knowledge boundaries in learning and knowledge sharing
Authors: Filstad Cathrine , Simeonova Boyka , Visser Max 
Published: February 2018

Purpose
The purpose of this study is to investigate the crossing of knowledge and power boundaries within a bureaucratic organization by using enterprise social media (ESM). (Carlile’s 2002) boundary crossing framework is used to guide this research.

Design/methodology/approach
This is a qualitative study based on semi-structured interviews and observations in a large Norwegian public sector organization.

Findings
The authors find that investigating crossing knowledge and power boundaries by using ESM is problematic at syntactic, semantic and pragmatic levels. ESM is used predominantly for sharing, storing and retrieving explicit knowledge, which is a display of crossing the information-processing boundary. Hence, the possibilities of shifts in formal power positions where all employees can participate on equal terms is not achieved. On the contrary, as shared meaning on how to use EMS, taking the perspective of other on how to share knowledge and thus creating new knowledge practices in EMS by overcoming these knowledge barriers is not evident. Therefore, examples of crossing the semantic and pragmatic knowledge boundaries are rarely found.

Research limitations/implications
The framework could be applied to a variety of contexts to further explore the role of ESM in learning and knowledge sharing and its ability to cross power and knowledge boundaries.

Originality/value
This paper addresses a gap in the literature around discussions of power, trust, boundary crossing and the use of ESM for knowledge sharing and learning.
A pilot study: Can the UFOV assessment be used as a repeated measure to determine timing of on‐road assessment in stroke?
Authors: McNamara Annabel , John Barr Christopher , Bond Malcolm J. , George Stacey 
Published: February 2018

Background/aimsUseful Field of View scores are predictive of on‐road performance post‐stroke. No objective data exist to determine if the Useful Field of View (UFOV) assessment can be used as a repeated measure in the post‐stroke population to determine timing of occupational therapy on‐road assessment as recovery occurs. The aims of this study were to determine whether there is a practice effect if the UFOV is administered at one, two and three months’ post‐stroke and to assess optimal time post‐stroke to refer to an on‐road assessment.MethodForty‐two participants, 17 men (40.5%), with a mean age of 71 years (SD 9.33) were randomly allocated to 1. Assessment group – UFOV at one, two and three months’ post‐stroke, 2. Control group—UFOV at three months’ post‐stroke. Parametric and non‐parametric tests were utilised depending on data distribution.ResultsNo significance was found between; three months’ subtest 1 (P = 0.463), three months’ subtest 2 (P = 0.729) and three months’ subtest 3 (P = 0.534) between the assessment and control groups. Both group's scores were combined to examine pass/fail rates of UFOV assessment to indicate timing of referral to on‐road assessments. At one month, 16.9% stroke survivors passed the UFOV, when reassessed at three months 69.1% passed and 28.6% again failed.ConclusionImprovements in scores at one month intervals over three months are due to improvements in abilities assessed by the UFOV as no practice effect was found to influence scores. UFOV scores performed at monthly intervals post‐stroke can be used to guide the timing of an occupational therapy on‐road assessment, with an increased likelihood of passing, as recovery occurs. This repeated use of the UFOV assessment can assist referral practices that best utilise driving rehabilitation programmes. Larger studies need to be conducted to confirm these results.
Increasing N deposition impacts neither diversity nor functions of deadwood‐inhabiting fungal communities, but adaptation and functional redundancy ensure ecosystem function

SummaryNitrogen deposition can strongly affect biodiversity, but its specific effects on terrestrial microbial communities and their roles for ecosystem functions and processes are still unclear. Here, we investigated the impacts of N deposition on wood‐inhabiting fungi (WIF) and their related ecological functions and processes in a highly N‐limited deadwood habitat. Based on high‐throughput sequencing, enzymatic activity assay and measurements of wood decomposition rates, we show that N addition has no significant effect on the overall WIF community composition or on related ecosystem functions and processes in this habitat. Nevertheless, we detected several switches in presence/absence (gain/loss) of wood‐inhabiting fungal OTUs due to the effect of N addition. The responses of WIF differed from previous studies carried out with fungi living in soil and leaf‐litter, which represent less N‐limited fungal habitats. Our results suggest that adaptation at different levels of organization and functional redundancy may explain this buffered response and the resistant microbial‐mediated ecosystem function and processes against N deposition in highly N‐limited habitats.
Afterword: materialities, care, ‘ordinary affects’, power and politics
Authors: Latimer Joanna 
Published: February 2018

AbstractIn this paper I explore how the papers in this volume offer ways of thinking about materialities of care in terms of political ecologies, including hierarchies of value as well as assemblages, in which strategic agendas are made present in everyday practices, with profound and ordinary affects, as well as effects. I show how power can work through the association of multiple and heterogeneous materials and social processes to create ‘thresholds’, as spaces through which people must pass in order to be included as patients, and which circulate specific imaginaries over what counts as an appropriate need. I go on to suggest how some material practices are made mundane and immaterial, that is inconsequential, so that by drawing attention to their importance in how care is done (or not done) the papers help disrupt the commonplace production and reproduction of the ‘neglected things’ (Puig de la Bellacasa) of healthcare environments, and by so doing help reimagine what is important for occasions to actually be caring. I then shift to thinking about a sensibility, one that is highly valued in this collection of articles, that helps illuminate different imaginaries of care to those that dominate healthcare environments, an approach that I have called elsewhere ‘relational extension’, and in the example I offer here show how shifts in extension as a form of motility disrupts stabilities and their reproduction, to accomplish different forms of world‐making.

Published: February 2018

Background and ObjectivesGambling Disorder (GD) is characterized by recurrent gambling behavior that is associated with significant impairment and distress, high psychiatric comorbidities, and high functional disability. The military veteran population appears particularly susceptible to developing the disorder, but relatively little has been studied among this population. The purpose of the present study is to investigate the clinical psychopathologies and comorbidities of veterans seeking treatment for problem gambling and how problem gambling may impact functioning.MethodsTreatment‐seeking veterans meeting criteria for GD (N = 61) underwent a structured clinical interview and completed the South Oaks Gambling Screen (SOGS), the Gambling Symptom Assessment Scale (G‐SAS), the Yale‐Brown Obsessive‐Compulsive Scale for Gambling Disorder (PG‐YBOCS), the Gambling Belief Questionnaire (GBQ), the Barratt Impulsiveness Scale (BIS‐11), and the Sheehan Disability Scale (SDS).ResultsVeterans seeking treatment for GD had high rates of psychiatric and addiction disorder comorbidities. Few veterans had previously sought treatment and most reported substantive challenges in social and occupational functioning. When determining how gambling‐related characteristics (ie, severity and cognitive distortions) impact function, severity of cognitive distortions was the strongest statistical predictor of overall functional disability.Conclusions and Scientific SignificanceThe findings from this study indicate that there is high comorbidity between GD and other psychiatric and addictive disorders, as well as social and occupational functioning. In addition, cognitive distortions related to gambling relate importantly to overall functioning and should be considered in the development of interventions for veterans with GD.
