Abstract
Reproduction is a critical fitness component in large herbivores. Biogeographic models predict that populations occurring at the edges of the range may have compromised reproductive rates because of inferior habitat at range peripheries. When reproductive rates are chronically low, ungulate populations may lack the resiliency to rebound quickly after periods of environmental stress, and this effect may be greatest for heat-sensitive organisms at their southern range limit. To assess the demographic vulnerability of moose (Alces alces), we studied relationships between reproductive rates, maternal age, and rump fat in the southernmost naturally occurring moose population in North America. For prime-aged moose in our study, pregnancy rates were high (92%), but moose aged &lt; 3 or &gt; 9 years had low pregnancy rates (32% and 38%, respectively). The relationship between rump fat and pregnancy was nonlinear such that a threshold of at least 2mm of rump fat yielded a high probability of being pregnant midwinter. In contrast, among pregnant moose, the probability of both producing a calf and recruiting it until spring increased linearly with rump fat. We also conducted a meta-analysis of pregnancy and twinning rates for adult (≥ 2 years) moose across a latitudinal gradient to compare reproductive rates from our study to other populations in North America. Moose living at southern latitudes tended to have lower reproductive rates than those living in the core of moose range, implying that southern moose populations may be demographically more vulnerable than northern moose populations.
The dynamic generalization of the Eshelby inclusion problem and its static limit
Authors: Ni Luqun , Markenscoff Xanthippi 
Published: July 2016

The dynamic generalization of the celebrated Eshelby inclusion with transformation strain is the (subsonically) self-similarly expanding ellipsoidal inclusion starting from the zero dimension. The solution of the governing system of partial differential equations was obtained recently by Ni & Markenscoff (In press.
J. Mech. Phys. Solids
(
doi:10.1016/j.jmps.2016.02.025
)) on the basis of the Radon transformation, while here an alternative method is presented. In the self-similarly expanding motion, the Eshelby property of constant constrained strain is valid in the interior domain of the expanding ellipsoid where the particle velocity vanishes (lacuna). The dynamic Eshelby tensor is obtained in integral form. From it, the static Eshelby tensor is obtained by a limiting procedure, as the axes' expansion velocities tend to zero and time to infinity, while their product is equal to the length of the static axis. This makes the Eshelby problem the limit of its dynamic generalization.
Microbial Mat Functional and Compositional Sensitivity to Environmental Disturbance
Authors: Preisner Eva C. , Fichot Erin B. , Norman R. Sean 
Published: July 2016

AbstractThe ability of ecosystems to adapt to environmental perturbations depends on the duration and intensity of change and the overall biological diversity of the system. While studies have indicated that rare microbial taxa may provide a biological reservoir that supports long-term ecosystem stability, how this dynamic population is influenced by environmental parameters remains unclear. In this study, a microbial mat ecosystem located on San Salvador Island, The Bahamas was used as a model to examine how environmental disturbance affects the activity of rare and abundant archaeal and bacterial communities and how these changes impact potential biogeochemical processes. While this ecosystem undergoes a range of seasonal variation, it experienced a large shift in salinity (230 to 65 g kg−1) during 2011-2012 following the landfall of Hurricane Irene on San Salvador Island. High throughput sequencing and analysis of 16S rRNA and rRNA genes from samples before and after the pulse disturbance showed significant changes in the diversity and activity of abundant and rare taxa, suggesting overall functional and compositional sensitivity to environmental change. In both archaeal and bacterial communities, while the majority of taxa showed low activity across conditions, the total number of active taxa and overall activity increased postdisturbance, with significant shifts in activity occurring among abundant and rare taxa across and within phyla. Broadly, following the post-disturbance reduction in salinity, taxa within Halobacteria decreased while those within Crenarchaeota, Thaumarchaeota, Thermoplasmata, Cyanobacteria, and Proteobacteria, increased in abundance and activity. Quantitative PCR of genes and transcripts involved in nitrogen and sulfur cycling showed concomitant shifts in biogeochemical cycling potential. Post-disturbance conditions increased the expression of genes involved in N-fixation, nitrification, denitrification, and sulfate reduction. Together, our findings show complex community adaptation to environmental change and help elucidate factors connecting disturbance, biodiversity, and ecosystem function that may enhance ecosystem models.

Authors: Lack Justin B. , Lange Jeremy D. , Tang Alison D. , Corbett-Detig Russell B. , Pool John E. 
Published: July 2016

ABSTRACTTheDrosophilaGenome Nexus is a population genomic resource that providesD. melanogastergenomes from multiple sources. To facilitate comparisons across data sets, genomes are aligned using a common reference alignment pipeline which involves two rounds of mapping. Regions of residual heterozygosity, identity-by-descent, and recent population admixture are annotated to enable data filtering based on the user’s needs. Here, we present a significant expansion of theDrosophilaGenome Nexus, which brings the current data object to a total of 1,122 wild-derived genomes. New additions include 306 previously unpublished genomes from inbred lines representing six population samples in Egypt, Ethiopia, France, and South Africa, along with another 193 genomes added from recently-published data sets. We also provide an alignedD. simulansgenome to facilitate divergence comparisons. This improved resource will broaden the range of population genomic questions that can addressed from multi-population allele frequencies and haplotypes in this model species. The larger set of genomes will also enhance the discovery of functionally relevant natural variation that exists within and between populations.
The Missing Link: Predicting Connectomes from Noisy and Partially Observed Tract Tracing Data

Published: July 2016

AbstractOur understanding of the wiring map of the brain, known as theconnectome, has increased greatly in the last decade, mostly due to technological advancements in neuroimaging techniques and improvements in computational tools to interpret the vast amount of available data. Despite this, with the exception of theC. elegansroundworm, no definitive connectome has been established for any species. In order to obtain this, tracer studies are particularly appealing, as these have proven highly reliable. The downside of tract tracing is that it is costly to perform, and can only be appliedex vivo. In this paper, we suggest that instead of probing all possible connections, hitherto unknown connections may be predicted from the data that is already available. Our approach uses a ‘latent space model’ that embeds the connectivity in an abstract physical space. Regions that are close in the latent space have a high chance of being connected, while regions far apart are most likely disconnected in the connectome. After learning the latent embedding from the connections that we did observe, the latent space allows us to predict connections that have not been probed previously. We apply the methodology to two connectivity data sets of the macaque and we demonstrate that the latent space model is successful in predicting unobserved connectivity, outperforming two alternative baselines in nearly all cases. Furthermore, we show how the latent spatial embedding may be used to integrate multimodal observations (i.e. anterograde and retrograde tracers) for the mouse neocortex. Finally, our probabilistic approach enables us to make explicit which connections are easy to predict and which prove difficult, allowing for informed follow-up studies.
Hedonic analysis of US fresh produce prices at direct-to-consumer sales outlets versus competing retailers
Authors: Martinez Steve W. 
Published: July 2016

Purpose– The purpose of this paper is to compare prices for fresh tomatoes, potatoes, peppers, and apples at direct-to-consumer sales outlets (e.g. farmers markets, roadside stands, on-farm stores) in the USA to grocery stores and supercenters, while controlling for other attributes.Design/methodology/approach– The author estimates a hedonic regression model to determine price differences at direct sales outlets, grocery stores, and supercenters in various regions and seasons of the year. The analysis is conducted using 2006 Nielsen Homescan data. Other product and market attributes are also considered, along with characteristics of the household sample.Findings– Prices at direct sales outlets are lower than grocery store prices throughout the year and across the USA. Prices at direct sales outlets for some product/location/season combinations were higher than or comparable to supercenter prices.Research limitations/implications– Future research is needed to examine how price differences may vary across the various types of direct marketing outlets.Originality/value– Few studies have examined price differences between direct sales outlets and conventional retail stores. No studies have used nationally representative data to analyze these price differences across produce type, season, and geographic areas.
Who cares for nutrition information at a restaurant? Food-related lifestyles and their association to nutrition information conscious behaviors
Authors: Choi Jinkyung 
Published: July 2016

Purpose
– People have become more health conscious about the food they eat on any occasion. As healthy dietary information has been released to the public in order to correspond with active public adaptation, more consumers have become aware of and are showing interest in new information related to health. The purpose of this paper is to utilize food-related lifestyle (FRL) instruments to explain nutrition information-conscious behaviors.

Design/methodology/approach
– This study used a cross-sectional survey design. A questionnaire was developed based on previous studies. A factor analysis and a cluster analysis were conducted to segment nutrition information-conscious behaviors of consumers. Participants were 200 and the survey was administered to citizens in South Korea. Exploratory factor analysis, cluster analysis, analysis of variance, Duncan’s multiple comparison tests, and χ2 test were used.

Findings
– Nine factors were identified and four clusters were established. These clusters were named: “personal value concern group,” “enthusiastic group,” “moderation group,” and “unconcerned group.” Each segment was significantly different in body satisfaction and nutrition information-conscious behaviors. Nutrients such as dietary fibers, sodium, and trans fat were considered differently by the four segments.

Originality/value
– Using an FRL instrument in relation to nutrition information-conscious behavior, interesting conclusions were drawn. Results of this study suggested that each segment has its characteristics in relation to nutrition information-conscious behaviors. Also it can be concluded that it is time for individuals to take responsibility for their own health problems.
Cheese perception in the North American market
Authors: Boatto Vasco , Rossetto Luca , Bordignon Paolo , Arboretti Rosa , Salmaso Luigi 
Published: July 2016

Purpose
– The purpose of this paper is to detect market segments where consumers have a different knowledge of domestic and imported Parmesan cheese in USA and Canada. The results may be helpful in understanding to what extend North America consumers appreciate Parmesan cheese and brands, Parmesan consumption and price while recognizing market segments according to consumer awareness, involvement and covariate effects.

Design/methodology/approach
– A class of mixture models, known as combination uniform binomial (CUB), is applied to survey data collected in USA and Canada. A questionnaire, filled out by 540 restaurant customers, collects opinions about consumption, purchase features and price. The CUB model estimates the two latent variables, known as feeling and uncertainty, explaining the respondent’s behavior as awareness and involvement variability while the CUB clustering procedure detects market segments.

Findings
– CUB results show that the Parmesan is a well-known cheese but also that a small share of consumers look for the place of origin. The model detects market segments where consumers express better awareness on taste, price and origin while the knowledge of imported Parmesan brands is lacking. Most of consumers, not paying attention to the origin, would hardly switch to the imported Parmesan because of higher price or because they are already satisfied of the domestic cheese.

Research limitations/implications
– The results suffer some restrictions in the sample representativeness. A further analysis, where the survey is done at retail and advances in CUB models, may improve the market segmentation procedure allowing a better generalization of results.

Practical implications
– The survey results highlights the appreciation and consumption of Parmesan cheese, especially for its taste, as well as a low perception of Italian brands. Consequently, trade companies should focussed their communication strategy on activities encouraging North American consumers to taste Italian Parmesan brands (e.g. tasting sessions, price promotions) instead of costly and less effective advertising campaigns.

Social implications
– Parmesan brand misunderstandings are often associated with market information asymmetry. The paper results show a market segmentation where purchases are mainly driven by Parmesan taste regardless of domestic or imported brands. Likely, the consumption of domestic Parmesan is well consolidated and it is not a consequence of brand information asymmetry.

Originality/value
– The CUB model is an innovative and flexible no parametric approach for evaluating consumer behavior and for segmenting the market while dealing with complex problems of food knowledge.
Consumers demand for products with animal welfare attributes
Authors: Akaichi Faical , Revoredo-Giha Cesar 
Published: July 2016

Purpose– The purpose of this paper is to assess Scottish consumers’ demand for animal welfare and organic pork. The paper also tried to answer the following questions: first, are animal-friendly pork and organic-pork complements or substitutes (competing)? Second, what is the relationship between pork products with different animal welfare labels (i.e. “freedom food” pork vs “specially selected pork”)? Third, does the demand for animal-friendly and organic pork vary with the level of deprivation of the area where consumers are living?Design/methodology/approach– The dataset used in the analysis is the Kantar Worldpanel dataset for Scotland, which contains weekly data of food and drink purchases for consumption at home, covering the period 2006-2011. The panel is representative of the Scottish population and covers about 3,694 households. The linear version of the almost ideal demand system was estimated. Then, the own- and the cross-price elasticities as well as the expenditure elasticities for the 22 food categories and products were computed.Findings– The results indicate that when the price of animal-friendly pork increases, consumers decrease their consumption of this product and substitute it by organic pork or regular pork, especially in the case of fresh pork, bacon and sausages. It was found that products with different animal welfare accreditation are substitutes in the eyes of Scottish consumers and are, therefore, competing for the market share of animal-friendly foods. The results also show that the demand for animal-friendly pork is more elastic in the most deprived areas in Scotland.Originality/value– To the best of the authors’ knowledge, this is the first study that estimates the demand for conventional, animal-friendly and organic pork using a scanner data in Scotland and controlling for the variation by area of deprivation.
Corruption and growth: a complex relationship
Authors: Mallik Girijasankar , Saha Shrabani 
Published: July 2016

Purpose
This paper investigates the corruption-growth relationship in a sample of 146 countries for the period – 1984-2009. While negative effects of corruption on growth have drawn economists’ interest in recent years, our main contribution is to examine the effects by employing the hierarchical polynomial regression to evaluate the relationship after controlling economic and institutional factors.

Design/methodology/approach
The results are estimated using panel generalized methods of moments.

Findings
The results challenge some of the findings that negative growth-corruption association in the literature but also provide some new inferences. The findings reflect that corruption is not always growth-inhibitory; for some countries it is growth-enhancing, which supports the “greasing-the-wheels” hypothesis.

Originality/value
The paper investigates the growth-corruption relationship using panel generalised methods of moments. Our results suggest that a cubic function best fitted the data. The finding suggests that in the medium corrupt countries corruption stimulates growth by reducing red-tape.
Service supply chain: strategic interaction and relationship value
Authors: Song Hua , Yu Kangkang , Chatterjee Samir Ranjan , Jia Jingzi 
Published: July 2016

PurposeThe purpose of this paper is to empirically investigate the linkages between strategic interaction and relationship value, with a variety of co-creating value strategies as conceptual mediators.Design/methodology/approachThis study reports on a field survey conducted in the Chinese manufacturing industry. A total of 180 questionnaires were sent to customers of service providers, and 120 valid responses were received, representing a response rate of 66.7 per cent. The data were then analyzed by using a number of statistical tools.FindingsThe results suggest that strategic interaction leads to a positive effect on the relationship value without any regard to the size of the customer. However, the mediating effect of product-based service is more significant for large-size customers, whereas the mediating effect of integrated managerial service is more significant for medium- and small-size customers.Originality/valueThis study explores how value might be created in a business-to-business context in a service supply chain from a relationship marketing perspective. It distinguishes product-based service and integrated managerial service as co-creating value strategies and further clarifies the different mechanisms underlying their relationships with strategic interaction between service supplier and customer. In particular, this study suggests that although strategic interaction may yield superior relationship value, the size of the customers will determine what kind of co-creating strategies would be preferred.

Authors: Bealt Jennifer , Fernández Barrera Jair Camilo , Mansouri S. Afshin 
Published: July 2016

Purpose– The purpose of this paper is to explore barriers and benefits of establishing relationships between humanitarian organizations (HOs) and logistics service providers (LSPs) in order to improve humanitarian disaster relief operations (DROs). The perceptions of a variety of actors are explored to determine key factors which influence collaboration.Design/methodology/approach– This study comprises of qualitative and quantitative methodological approaches. A comprehensive literature review was undertaken alongside an online survey with a variety of respondents. Descriptive statistics, data visualization and qualitative data analysis were implemented to analyse survey results. A follow-up survey and interviews with LSPs validated the results.Findings– The research presents the opinions of a variety of actors involved in DROs and reveals barriers which affect HO/LSP collaboration. Explanations for these barriers and possible solutions to mitigate them are disclosed. The findings also uncover gaps between research and practice; providing new insights into behaviour in the humanitarian field.Practical implications– The authors provide an in-depth understanding of the barriers and challenges faced in this field and suggest a reevaluation of corporate decision making in order to increase trust between LSPs and HOs. The authors identify future research topics including the impact of donors and military organizations on HO decision making, and analysis of variables which may affect the formation of collaborative partnerships.Originality/value– The authors introduce a unique empirical insight into the perspectives of HOs, LSPs and academics and offers suggestions for mitigating the numerous barriers associated with successful collaborative partnerships between HOs and LSPs.
Capabilities and competencies in humanitarian operations
Authors: Apte Aruna , Gonçalves Paulo , Yoho Keenan 
Published: July 2016

Purpose
– Both the military and non-military organizations (NMO) bring assets, skills, and capabilities to a humanitarian crisis, however, their capabilities and competencies are very diverse. Identification of the specific competencies and capabilities that are core to these types of organizations can enable better planning by both military and NMOs, allowing them to achieve greater effectiveness and efficiency in the humanitarian response. The purpose of this paper is to explore the core capabilities of the military and NMOs engaged in humanitarian operations.

Design/methodology/approach
– The work builds on existing literature on the core competency of the corporation. The authors extend the concept of the ability to identify, cultivate, and exploit the core capabilities in the private sector to the organizations that want to respond efficiently and effectively to disasters. The authors develop a core competencies test for such organizations.

Findings
– The research identifies the competencies and capabilities that are core to the US military and NMOs for humanitarian assistance and disaster relief. By identifying such abilities the authors establish a vein of research for exploring the role of such organizations to facilitate greater understanding among academics, policy makers, and decision makers in public administration, public health, and international aid.

Originality/value
– Existing literature in humanitarian logistics does not adequately address identification of those competencies and capabilities that are core to the military organizations and NMOs and are most needed during the operational life cycle of a humanitarian crisis. In addition to identifying them, the authors compare the core capabilities of the military and NMO.
