The conditioning function of rating mechanisms for consumers in the sharing economy
Authors: Newlands Gemma , Lutz Christoph , Fieseler Christian 
Published: March 2019

Purpose
The purpose of this paper is to explore how rating mechanisms encourage emotional labor norms among sharing economy consumers.

Design/methodology/approach
This study follows a mixed-methods research design. Survey data from 207 consumers were used to quantify the impact of three distinct rating dimensions on a consumer behavioral outcome (emotional labor). In the second step, 18 focus groups with 94 participants were used to investigate the conditioning functions of ratings in more depth.

Findings
Rating mechanisms condition consumers toward performing socially desirable behaviors during sharing transactions. While consumers accept the necessity of bilateral rating mechanisms, they also recognize their coercive nature. Furthermore, the presence of bilateral rating mechanisms leads to negative outcomes such as annoyance and frustration.

Originality/value
This study contributes to sharing economy literature by examining bilateral rating mechanisms as a means of behavioral conditioning for consumers. This study points to improvements in platform design and informs theory on tripartite markets as well as trust.
Does usage of enterprise social media affect employee turnover? Empirical evidence from Chinese companies
Authors: Yingjie Lu , Deng Shasha , Pan Taotao 
Published: March 2019

Purpose
The purpose of this paper is to examine how the usage of enterprise social media (ESM) affects eventual employee turnover.

Design/methodology/approach
This study developed a theoretical model based on the proposition that different ESM usage behaviors (utilitarian use, hedonic use and social use) have different effects on employee turnover, and job type and job level can moderate the effect of ESM usage on turnover. The model was examined empirically using 1,791 employee samples from a large high-tech manufacturing enterprise deploying ESM.

Findings
The results indicate that the utilitarian and social use of ESM has negative effects on turnover, but the hedonic use of ESM has positive effects on turnover. Furthermore, for employees working in different job types and job levels, there are significant differences concerning the effect of ESM usage on their turnover.

Practical implications
ESM managers should encourage employees to use ESM for utilitarian needs and social support but restrict excessive use of ESM for leisure. In addition, different ESM use policies depending upon job types and job levels could be adopted to retain valuable employees.

Originality/value
Few studies have focused on how usage of ESM affects eventual employee turnover. Given the lack of theoretical research and empirical evidence, the authors developed a theoretical model and conducted an empirical study to fill the research gap.
Impact of bargaining power on supply chain profit allocation: a game-theoretic study
Authors: Prasad Sanjay , Shankar Ravi , Roy Sreejit 
Published: March 2019

Purpose
The purpose of this paper is to study the impact of bargaining powers of firms in supply chain coordination. It studies selected aspects of bargaining powers, namely, impatience, breakdown probability and outside options, and uses a bargaining-theoretic approach to analyze surplus allocation in a coordinated supply chain.

Design/methodology/approach
This paper proposes one-supplier one-buyer infinite horizon supply chain coordination game, where suppliers and buyers negotiate for the allocation of supply chain surplus arising out of supply chain coordination. Various aspects of the bargaining power of the negotiating parties are modeled and the paper studies impact of power levels on the results of the bargaining game.

Findings
A significance of impatience on the bargaining process and the surplus split has been established. This paper also demonstrates a rather counter-intuitive aspect of bargaining that the impatience (as perceived by the other party) can improve the bargaining position and therefore share of profits.

Research limitations/implications
This paper has limited its analysis to three key components of bargaining power. Future works can study other aspects of bargaining power, namely information asymmetry, learning curve, inside options, etc. Further, the paper has considered an infinite horizon model – this assumption can be relaxed in future research.

Practical implications
Equations to derive optimal split of the surplus have been derived and can be leveraged to design an autonomous bargaining agent to discover equilibrium profit splits in a cloud or e-commerce setting. Further, insights from this paper can be leveraged by managers to understand their relative bargaining power and drive to obtain the best profit split.

Originality/value
This paper establishes that impatience (in terms of counter-offer probability) has a significant impact on the bargaining position and on the split of the surplus that the firm can get for themselves. It establishes the advantage of higher levels of impatience, provided the other party recognizes the impatience and factors it in their decision-making process.
End consumer’s value creation in a nature-based tourism service
Authors: Alakoski Leena , Tikkanen Irma 
Published: March 2019

Purpose
The purpose of this paper is to increase understanding of end consumer’s value creation in the context of Finnish nature-based tourism from the viewpoint of the customer-dominant logic (CD logic) of service.

Design/methodology/approach
Existing research on the CD logic of service and value creation, consumer value and value creation as a hierarchical process is reviewed. The exploratory research design was applied. The data were constituted of 40 end consumers’ interviews. Based on the means-end chain model, a laddering interview was applied.

Findings
The findings indicated that end consumer’s value created in a nature-based tourism service included five final value categories. Those categories were related to emotions and feelings, enjoyment, fun and even lifetime memories. They indicated long-term characteristics of value, individually created value, collective experience and shared value.

Practical implications
The findings increased understanding of end consumer’s value creation as a process. The paper provided ideas for developing better nature-based tourism service offerings, value propositions and insights into end consumer’s value creation in terms of individual and shared value. The findings are valuable for nature-based tourism researchers and stakeholders.

Originality/value
New knowledge on end consumer’s value creation process was created by presenting the hierarchical value maps. The five final value categories indicated the value-in-use. The final value categories emphasised either individual or shared value, which included the end consumer’s life and previous experiences. The preliminary findings will help to develop hypotheses and research problems for future research.

Authors: Chou Shih Yung , Ramser Charles 
Published: March 2019

PurposeThe purpose of this paper is to develop a theoretical model that addresses how student citizenship behavior (CB) may be motivated by management of impression in a team-based project using peer evaluations.Design/methodology/approachThis study applies impression management (IM) theory as the theoretical lens to explore the impact of IM tactics, in the forms of task-, self- and peer-focused tactics, on student CB in a team-based project using peer evaluations.FindingsThis paper posits that task-, self- and peer-focused IM tactics positively influence a student’s CB in a team-based project when peer evaluations are used. Furthermore, it is proposed that the relative weight of a peer evaluation strengthens the relationship between the three IM tactics and a student’s CB.Originality/valueFrom a theoretical standpoint, this study extends IM–CB relationship from the employment setting to the academic setting. More importantly, this study offers crucial recommendations for instructors that may help improve the effectiveness of peer evaluations.
Analysis or intuition? Reframing the decision-making styles debate in technological settings
Authors: Bullini Orlandi Ludovico , Pierce Paul 
Published: March 2019

PurposeThe debate over intuitive vs analytical decision-making styles began almost 40 years ago and had yet to deliver definite answers. The debate – however – has led to divergent theoretical stances and empirical results. The purpose of this paper is to investigate the role of these information processing styles in customer-related decision-making in the context of mobile technologies.Design/methodology/approachThe hypotheses are derived from the contrasting theoretical propositions and empirical evidence present in the debate around decision-making styles. The study also introduces and investigates the moderating role of environmental dynamism (ED). Analyses and results are based on survey research that involves 251 managers with responsibility for organizational decision-making processes.FindingsThe study’s findings suggest that both intuitive and analytical styles are relevant in the actual context characterized by mobile technologies. Intuition still plays a central role in managers’ decision-making processes, but when the industry environment is highly dynamic analytical information processing also plays an essential role in supporting organizational responsiveness and performance.Practical implicationsThis study can help managers in reconsidering the way in which they employ analytical or intuitive information processing activities inside their decision making at different levels of ED.Originality/valueThe novelty of this paper relies on testing hypothesis simultaneously developed by both the theoretical stances favorable to intuitive and to analytical information processing. Besides, it tests these hypotheses in the actual empirical context characterized by a transformed scenario in terms of data availability.
Amplitude variation with incident angle and azimuth inversion for Young's impedance, Poisson's ratio and fracture weaknesses in shale gas reservoirs
Authors: Pan Xinpeng , Zhang Guangzhi 
Published: March 2019

ABSTRACTBy analogy with P‐ and S‐wave impedances, the product of Young's modulus and density can be termed as Young's impedance, which indicates the rock lithology and brittleness of unconventional hydrocarbon reservoirs. Poisson's ratio is also an effective indicator of rock brittleness and fluid property of unconventional reservoirs, and fracture weaknesses indicate the fracture properties (fracturing intensity and fracture fillings) in fracture‐induced unconventional reservoirs. We aim to simultaneously estimate the Young's impedance, Poisson's ratio and fracture weaknesses from wide‐azimuth surface seismic data in a fracture‐induced shale gas reservoir, and use the horizontal transversely isotropic model to characterize the fractures. First, the linearized PP‐wave reflection coefficient in terms of Young's impedance, Poisson's ratio, density and fracture weaknesses is derived for the case of a weak‐contrast interface separating two weakly horizontal transversely isotropic media. In addition, an orthorhombic anisotropic case is also discussed in this paper. Then a Bayesian amplitude variation with incident angle and azimuth scheme with a model constraint is used to stably estimate Young's impedance, Poisson's ratio and fracture weaknesses with only PP‐wave azimuthal seismic data. The proposed approach is finally demonstrated on both synthetic and real data sets with reasonable results.
Variation in growth and defence traits among plant populations at different elevations: Implications for adaptation to climate change
Authors: Buckley James , Widmer Alex , Mescher Mark C. , De Moraes Consuelo M. 
Published: March 2019

Abstract

Alpine plants occurring at high elevation are vulnerable to ongoing climate change, yet relatively little is known about the potential for high‐elevation species to adapt to changing environmental conditions. In particular, the extent to which high‐elevation plants will be able to resist predicted increases in the intensity of biotic interactions, such as herbivory, remains unclear.

Species distributed across broad elevational ranges provide an opportunity to investigate evolutionary mechanisms and traits involved in adaptation to varying abiotic and biotic environments. This study focused on the perennial alpine plant Arabis alpina and combined field surveys and climate chamber experiments to test for intraspecific genetic divergence in traits related to growth and defence against herbivores. We screened multiple populations from low, intermediate and high elevations across a broad geographic area, characterising differences in growth form, leaf structural traits, palatability for herbivores and defensive chemistry. We then quantified the proportion of variation explained by elevation and population‐level effects.

Our results document within‐species genetic divergence in multiple traits relevant for adaptation to the different abiotic and biotic pressures experienced at low and high elevations. Rates of herbivore damage declined with increasing elevation in the field, but plants from high‐ and intermediate‐elevation populations were generally more palatable for specialist herbivores than those from low‐elevation populations in feeding assays. Elevational clines were also observed in several glucosinolate defence compounds, and leaf herbivory more strongly induced glucosinolates in plants from high‐elevation populations than in those from low‐elevation populations. Leaf trichome density and growth form also diverged among populations contributing to growth–defence phenotypes associated with different elevations.

However, populations from similar elevations often differed significantly in both growth‐ and defence‐related traits, with trait variation often better explained by population‐level effects than by elevation alone.

Synthesis. Arabis alpina exhibits patterns of genetic variation in growth and defence traits consistent with adaptation to different elevations. However, populations from similar elevations also diverge in many of these ecologically relevant traits. Together, the extent of the observed trait variation suggests that this alpine species has considerable potential to adapt to a changing biotic environment.
Differential gene expression associated with fungal trophic shifts along the senescence gradient of the moss Dicranum scoparium
Authors: Chen Ko‐Hsuan , Liao Hui‐Ling , Bellenger Jean‐Philippe , Lutzoni François 
Published: March 2019

SummaryBryophytes harbour microbiomes, including diverse communities of fungi. The molecular mechanisms by which perennial mosses interact with these fungal partners along their senescence gradients are unknown, yet this is an ideal system to study variation in gene expression associated with trophic state transitions. We investigated differentially expressed genes of fungal communities and their host Dicranum scoparium across its naturally occurring senescence gradient using a metatranscriptomic approach. Higher activity of fungal nutrient‐related (carbon, nitrogen, phosphorus and sulfur) transporters and Carbohydrate‐Active enZyme (CAZy) genes was detected toward the bottom, partially decomposed, layer of the moss. The most prominent variation in the expression levels of fungal nutrient transporters was from inorganic nitrogen‐related transporters, whereas the breakdown of organonitrogens was detected as the most enriched gene ontology term for the host D. scoparium, for those transcripts having higher expression in the partially decomposed layer. The abundance of bacterial rRNA transcripts suggested that more living members of Cyanobacteria are associated with the photosynthetic layer of D. scoparium, while members of Rhizobiales are detected throughout the gametophytes. Plant genes for specific fungal–plant communication, including defense responses, were differentially expressed, suggesting that different genetic pathways are involved in plant‐microbe crosstalk in photosynthetic tissues compared to partially decomposed tissues.
Identification of a Suspect in a Murder Case through Recovery of Fingermarks from a Fired Cartridge Case
Authors: Girelli Carlos M. A. , Segatto Breno R. 
Published: March 2019

AbstractDuring the period of one year, the Police of the State of Espírito Santo in Brazil analyzed 1,431 cartridge cases obtained from crime scenes and seizures. The cartridges were subjected to a development sequence (cyanoacrylate fuming + gun bluing + fluorescent dying), and panoramic images of the developed fingermarks were generated based on the photographs taken during the rotation of the cartridges. Ridge details were observed in 50 cartridges, but only in 5 cartridges, the marks were considered with value for identification. The fingermarks were searched in the Automated Fingerprint Identification System (AFIS) of the Brazilian Federal Police and, in one case, it was possible to obtain the suspect's identification. In our knowledge, this is the first case in Brazil of identification of a suspect based on a fingermark recovered from a fired cartridge case.
Silicosis: Diagnosis and Medicolegal Implications
Authors: Bukovitz Brandon , Meiman Jonathan , Anderson Henry , Brooks Erin G. 
Published: March 2019

AbstractDespite well‐publicized sources of occupational hazard, silicosis continues to threaten industrial workers in the United States. We performed a retrospective search of the University of Wisconsin electronic pathology database to retrieve autopsy cases of silicosis and collaborated with the Wisconsin Department of Health Services to obtain statewide epidemiologic data regarding silicosis morbidity/mortality since 2003. Three silicosis autopsy cases were retrieved: all were men with ≥ 30 years of occupational crystalline silica exposure and similar histologic features of collagenous pulmonary nodules with admixed refractile particles. Overall, our state exceeds the national rate of silicosis‐related hospitalizations and mortality, that is, 10.1 hospitalizations per million WI residents versus 1.2 nationally and 1.2 deaths per million WI residents versus 0.4 nationally. Surveillance is crucial to identify emerging occupational hazards and protect workers. A diagnosis of silicosis must be carefully considered at autopsy since it carries substantial implications for worker's compensation, compensatory losses, and employer liability.
Performance Evaluation of a Registered Ballistic Database Using the Evofinder® System
Authors: Li Yuesong , Lin Sheng , Luo Yaping , Mi Zhongliang 
Published: March 2019

AbstractFirearms for police in China are registered along with their fired bullets and cartridge cases. A Registered Ballistic Database (RBD) of 1000 Norinco QSZ‐92 pistols with registered ammunition was established and was evaluated through the Evofinder® system. In this research, 1000 bullets and 1000 cartridge cases were randomly selected and correlated against an RBD of 2996 bullets and 2999 cartridge cases. Examiners found that successful identifications all ranked 1st, supported with land (100%), groove (97%) engraved areas, and primary marks (85.6%) for bullets, and firing pin impressions (99.8%), and breech face marks (99.9%) for cartridge cases. Two known matches (KM) for the same pistol rank in the top two (100%). The distribution of similarity scores varies from marks; however, the Evofinder® system could still effectively distinguish known matches from known nonmatches (KNM) for either bullets or cartridge cases. This study demonstrates the efficiency of the RBD.

Epidemiology and survival of Merkel cell carcinoma in New Zealand: A population‐based study between 2000 and 2015 with international comparison
Authors: Lee Young , Chao Phillip , Coomarasamy Christin , Mathy Jon A 
Published: March 2019

AbstractBackground/ObjectivesMerkel cell carcinoma is an aggressive neuroendocrine skin cancer. Australian studies report high incidence and poor survival rates compared internationally. While New Zealand has a comparable UV index and racial composition to Australia, survival outcomes are currently unknown. The role of Merkel cell polyoma virus in oncogenesis of Merkel cell carcinoma is an active area of research. We describe the incidence and survival of Merkel cell carcinoma in New Zealand with correlation to demographic and clinical factors including regional polyoma virus prevalence.MethodsRetrospective study of population‐based data from the New Zealand Cancer Registry. Incidence rates were directly standardised to the US standard 2000 population. Survival was investigated using Kaplan–Meier and multivariable Cox regression models.ResultsSix hundred and one cases were diagnosed in New Zealand between 2000 and 2015. The overall incidence rate was 0.96/100 000 population. Merkel cell carcinoma is more common in males, elderly and on sun‐exposed areas. Eighteen percent of patients were diagnosed with distant metastasis at time of presentation. The overall 5‐year survival rate and relative 5‐year survival rate were 31% and 45%, respectively. Mortality was 1.9 and 2.5 times higher for stage III and IV disease, respectively, relative to stage I/II disease. Patients over age 80 had twice the mortality compared to those aged 60–69.ConclusionsNew Zealand has a high incidence of Merkel cell carcinoma and poor survival outcomes when compared internationally. We have the highest proportion of distant metastatic disease at time of diagnosis. Further research into the role of nonpolyoma‐related Merkel cell carcinoma is warranted to improve Merkel cell carcinoma outcomes in New Zealand and abroad.
Not About Land, Not Quite a Grab: Dispersed Dispossession in Rural Russia
Authors: Vorbrugg Alexander 
Published: March 2019

AbstractIn most literature in geography and agrarian studies, rural dispossession is neatly related to land rights or access, a trend that increased with debates about the recent wave of farmland investments worldwide. Drawing on long‐term fieldwork in rural Russia, this paper critiques that focus and the assumed nexus between rural dispossession and farmland, as is prevents an understanding of more dispersed stakes, modes and temporalities of dispossession. I introduce the concept of dispersed dispossession which advances our understanding of social and relational objects of dispossession beyond natural resources (such as sustaining institutions and infrastructures), and the tangled, complex, often slow and silent modes and temporalities of dispossession beyond spectacular events. I show how the concept sheds new light on current agrarian change in Russia, and how it contributes to debates on (rural) dispossession and “land grabs” more generally.
