Published: September 2017

ABSTRACTA widely accepted two-wave scenario of human settlement of Oceania involves the first out-of-Africa migration ca 50,000 ya, and one of the most geographically-widespread dispersals of people, known as the Austronesian expansion, which reached the Bismarck Archipelago by about 3,450 ya. While earlier genetic studies provided evidence for extensive sex-biased admixture between the incoming and the indigenous populations, some archaeological, linguistic and genetic evidence indicates a more complicated picture of settlement. To study regional variation in Oceania in more detail, we have compiled a genome-wide dataset of 823 individuals from 72 populations (including 50 populations from Oceania) and over 620,000 autosomal SNPs. We show that the initial dispersal of people from the Bismarck Archipelago into Remote Oceania occurred in a “leapfrog” fashion, completely by-passing the main chain of the Solomon Islands, and that the colonization of the Solomon Islands proceeded in a bi-directional manner. Our results also support a divergence between western and eastern Solomons, in agreement with the sharp linguistic divide known as the Tryon-Hackman line. We also report substantial post-Austronesian gene flow across the Solomons. In particular, Santa Cruz (in Remote Oceania) exhibits extraordinarily high levels of Papuan ancestry that cannot be explained by a simple bottleneck/founder event scenario. Finally, we use simulations to show that discrepancies between different methods for dating admixture likely reflect different sensitivities of the methods to multiple admixture events from the same (or similar) sources. Overall, this study points to the importance of fine-scale sampling to understand the complexities of human population history.
Effects of multiple sources of genetic drift on pathogen variation within hosts
Authors: Kennedy David A. , Dwyer Greg 
Published: September 2017

AbstractChanges in pathogen genetic variation within hosts alter the severity and spread of infectious diseases, with important implications for clinical disease and public health. Genetic drift may play a strong role in shaping pathogen variation, but analyses of drift in pathogens have oversimplified pathogen population dynamics, either by considering dynamics only at a single scale (within hosts, between hosts), or by making drastic simplifying assumptions (host immune systems can be ignored, transmission bottlenecks are complete). Moreover, previous studies used genetic data to infer the strength of genetic drift, whereas we test whether the genetic drift imposed by pathogen population processes can be used to explain genetic data. We first constructed and parameterized a mathematical model of gypsy moth baculovirus dynamics that allows genetic drift to act within and between hosts. We then quantified the genome-wide diversity of baculovirus populations within each of 143 field-collected gypsy moth larvae using Illumina sequencing. Finally, we determined whether the genetic drift imposed by host-pathogen population dynamics in our model explains the levels of pathogen diversity in our data. We found that when the model allows drift to act at multiple scales, including within hosts, between hosts, and between years, it can accurately reproduce the data, but when the effects of drift are simplified by neglecting transmission bottlenecks and stochastic variation in virus replication within hosts, the model fails. Ade novomutation model and a purifying selection model similarly fail to explain the data. Our results show that genetic drift can play a strong role in determining pathogen variation, and that mathematical models that account for pathogen population growth at multiple scales of biological organization can be used to explain this variation.
The foraging perspective on economic choice
Authors: Hayden Benjamin Y. 
Published: September 2017

AbstractForaging theory offers an alternative foundation for understanding economic choice, one that sees economic choices as the outcome of psychological processes that evolved to help our ancestors search for food. Most of the choices encountered by foragers are between pursuing an encountered prey (accept) or ignoring it in favor of continued search (reject). Binary choices, which typically occur between simultaneously presented items, are special case, and are resolved through paired alternating accept-reject decisions limited by the narrow focus of attention. The foraging approach also holds out promise for helping to understand self-control and invites a reconceptualization of the mechanisms of binary choice, the relationship between choosing and stopping, and of the meaning of reward value.HighlightsForaging provides a basis for modeling economic choice based on adaptivenessForaging choices are accept-reject; foraging models interpret binary choice accordinglyThe foraging view offers a different perspective on self-control decisionsEconomic and stopping decisions may have a common basis
Value co-creation in the beverage and food industry
Authors: Tardivo Giuseppe , Thrassou Alkis , Viassone Milena , Serravalle Francesca 
Published: September 2017

Purpose
The purpose of this paper is to define and describe how consumers may constitute an integral part of small and medium enterprises’ (SMEs) value co-creation process in the food and beverage (F&B) industry, and to provide practicable implementation recommendations to firms in the Piedmont region that are important and prominent in this sector.

Design/methodology/approach
The research methodology rests on a multiple case study design, applied to three F&B Piedmont SMEs that produce beer, water and starters: Baladin, Lurisia and Galfré.

Findings
Results show an increasing awareness by firms of the important role played by customers in value co-creation, though limited to specific roles in the case of SMEs.

Research limitations/implications
The research is limited by its exploratory nature, though the findings and conclusions drawn provide a solid foundation for further development and testing on the subject.

Practical implications
The case studies’ results allow the reader to understand the importance of the increasing awareness of the role played by customers in value co-creation, especially on the WWB, where costs are minimizing.

Originality/value
The research’s value stems from fact that there are few existing studies on the ways to engage customers in value co-creation. Moreover, these studies, contrary to the present research, are largely theoretical and either have no direct applicability or are limited to a single case.
Openness and collaboration in the food sector: mapping the field
Authors: Procopio Schoen Ana 
Published: September 2017

Purpose
Research in institutional openness and collaboration-based innovation has advanced considerably in the last decade. The complexity and heterogeneity of innovation, however, turn the one-fits-all approach questionable and unveil the need to address several and different settings and industries. The purpose of this paper is to address this demand by mapping the themes covered in the research under the collaborative innovation umbrella having specifically the food and drink sector as a context.

Design/methodology/approach
The paper is based on secondary data sources, namely, a literature review of open innovation in the food and beverage (F&B) sector.

Findings
This paper builds upon a framework to classify the extant research in open innovation in the food industry and position the advancements in comparison to the general literature in the field. The categorization of the publications shows that topics like the role of networks, innovation systems, user-innovation and research and development alliances have attracted mostly attention so far, but there is still a demand for deeper and more comprehensive investigations. The field would also profit from inquiries that deal with mindset and managerial capabilities, cross-industry partnerships, converging value chains and globalization of innovation, among others.

Originality/value
To the authors’ knowledge, this is among the first papers to map research topics and research designs that have been covered to date on the field of open and collaborative innovation in the F&B industry.

Authors: Fiore Mariantonietta , Gallo Crescenzio , Tsoukatos Evangelos , La Sala Piermichele 
Published: September 2017

Purpose
Healthy and safety food issues are more and more becoming the purchasing process core of conscious consumer. “Type 1” wheat flour means higher protein and ash content. The purpose of this paper is to investigate the attributes usually referred to the characteristics of wheat flour known to consumers and at implementing a predictive model of purchasing that allows to make correct decisions without the necessary experience of a real human expert.

Design/methodology/approach
In order to investigate the research aims of the paper, an online survey was carried out and conducted by means of the Google Forms in the detection time January-April 2016. The online survey collected responses from 467 Italian respondents asked to give feedback about their buying habits of various types of flour. The responses were analyzed through a data mining approach. This paper implements predictive analytics to create a statistical model of future behavior by means of a machine learning algorithms.

Findings
In line with recent healthy and dynamic trends in the food industry, conscious consumer seems to be willing to pay a price for “type 1” wheat flour that is four times higher than the price related to the basic types of wheat flour.

Social implications
Consumer seems not to know well the “type 1” wheat flour and its healthy characteristics; then, it should be crucial to implement promotional strategies and marketing hand in hand. Promotion can be a key element in putting across the health benefits of special kinds of wheat flour.

Originality/value
Highlighting health issues about the “type 1” wheat flour gives insights and sheds some light on the crucial need of changing eating and purchasing behavior. Then, originality of this paper can be found in the used predictive algorithm of the artificial intelligence.
Longitudinal patterns of unmet needs during Texas floods, May-June 2015
Authors: Tai Teresa Wai Chi , Lee Jee Young , Bame Sherry I. 
Published: September 2017

Purpose
In Spring 2015, Texas experienced record-breaking floods, causing deaths, injuries, and widespread property and infrastructure damage. However, little is known about those who encountered access barriers to disaster support in Texas. The purpose of this paper is to examine the unmet disaster-related needs from 2-1-1 calls during evacuation, flooding, and early recovery phases.

Design/methodology/approach
The 2-1-1 Texas Information and Referral Network’s caller database was used to identify real time, non-emergency, unmet disaster-related caller needs longitudinally. The two-month study period included a baseline week before flashflood (05/01/2015) into early recovery (06/30/2015). Caller unmet needs were categorized and graphed by type daily throughout the study period.

Findings
Of the 4,880 disaster-related 2-1-1 calls from Texas’ 254 counties, 1,183 callers needed housing help, compared to 442 utilities, 409 food and 109 medically related assistance. Total calls quickly peaked at 405 calls/day during Memorial Day weekend when Greater Houston flooded. Despite total calls decreasing gradually during recovery, they remained four times higher than baseline. Unmet needs varied by type, especially during early recovery. Housing, food, and medical unmet needs surged when Houston flooded. Although medical calls were lowest volume than other basic needs, demand for medical assistance had a higher threshold throughout early recovery.

Practical implications
Examination of unmet needs over disaster phases identified longitudinal patterns of demand and effectiveness of disaster management efforts.

Originality/value
Using real-time 2-1-1 data to monitor types of unmet demand is valuable to tailor timely and effective disaster support, reduce access barriers, and allocate disaster support services and supplies to the vulnerable communities.

Authors: Guo Xuesong , Kapucu Naim 
Published: September 2017

PurposeAlthough many disaster resettlement programs are implemented throughout the world, their ramifications continue to challenge our understanding of scope, impact, context, and nature of efforts to rebuild livelihoods. The purpose of this paper is to examine involved rural farmers’ livelihood risk perceptions (LRPs) in Southern Shaanxi Disaster Resettlement based on the case of Ziyang County.Design/methodology/approachUtilizing a livelihood risk perspective, this paper identified factors contributing to LRPs. The research categorized the involved rural farmers into groups and explored the factors affecting their LRPs using decision tree (DT).FindingsAnalyzing LRPs of different groups, this paper derived influential factors and the decision rules followed by groups. Additionally, critical factors were discussed according to their relative importance for decision making and to propose some intervention measures for effectiveness.Originality/valueThe results and implications enhance understanding on how local community members perceive the problem or risk in disaster resettlement. The application of a DT also provides methodological contributions for risk analysis and disaster preparedness.
Corporate accountability in the Samarco chemical sludge disaster
Authors: da Costa Karen 
Published: September 2017

Purpose
The purpose of this paper is to explore avenues of corporate accountability in disasters, using the Samarco chemical sludge disaster, which took place in 2015 in Brazil, as case study.

Design/methodology/approach
The paper considers possible ways of enhancing corporate accountability in disasters, focusing on one particular international mechanism on multinational enterprises (MNEs), which addresses both human rights and environmental issues. The research is based on the location and assessment of a variety of written sources (i.e. normative instruments, academic literature, publications by practitioners, civil society organizations, and the media). The paper makes suggestions on the potential of using existent international accountability mechanisms in similar disasters.

Findings
The paper identifies key measures taken by national authorities to address the disaster. It also considers how the Organization for Economic Cooperation and Development Guidelines for MNEs could be used to pursue corporate accountability.

Research limitations/implications
This is a desk-based research, chiefly conducted on documental analysis rather than fieldwork.

Practical implications
The paper might provide useful insights for organizations and communities facing similar challenges linked to multinational corporate activities that adversely affect human rights and the environment.

Originality/value
The study brings to attention normative standards relatively unknown to the disaster community, which may help raise interest on them, and lead to their potential use in future disaster situations. Furthermore, to date the Samarco chemical sludge has received scant attention from the academic literature.
Regulating disasters? The role of international law in disaster prevention and management
Authors: Aronsson-Storrier Marie , da Costa Karen 
Published: September 2017

Purpose
The purpose of this paper is to explore the role of international law in disaster prevention and management, with a particular focus on the emerging field of international disaster law (IDL), and its relationship with international human rights law. It further introduces the four articles of the special column of this journal issue, dedicated to disasters and international law.

Design/methodology/approach
The analysis is based upon primary sources of legislation and policy, as well as academic literature on disasters and international law.

Findings
Although the field of IDL is in its infancy, the authors argue that this emergent area does have the potential to gain widespread recognition as a distinct field of law, and that this may benefit the wider disaster management community.

Originality/value
The paper introduces key legal features and themes relating to international law and disasters, highlighting their relevance for disaster management. The added value is to widen the discussion on aspects of disasters regulated by international law, thus facilitating the future exchange with other academic subjects and operational fields.

Published: September 2017

Purpose
Although the importance of climate change is generally acknowledged, its impacts are often not taken into account explicitly when planning development projects. This being due to limited resources, among others, this paper aims to propose a simple and low-cost approach to assess the viability of human activities under climate change.

Design/methodology/approach
Many human activities are feasible only within a narrow range of climatic conditions. Comparing such “climate corridors” with future climate projections provides an intuitive yet quantitative means for assessing needs for, and the viability of, adaptation activities under climate change.

Findings
The approach was tested within development projects in Pakistan, Peru and Tajikistan. The approach was shown to work well for forestry and agriculture, indicating positive/negative prospects for wheat in two districts in Pakistan, temperature constraints for maize in Peru and widening elevation ranges for walnut trees in Tajikistan.

Practical implications
Climate corridor analyses feed into the preparation of Local Adaptation Plans of Action in Pakistan.

Originality/value
The simplicity and robustness of climate corridor analysis allow for efficient analysis and communication of climate change impacts. It works when data availability is limited, but it can as well accommodate a wide range of complexities. It has proven to be an effective vehicle for mainstreaming climate change into adaptation planning.
Exploring HR practitioners’ perspective on employer branding and its role in organisational attractiveness and talent management
Authors: Maheshwari Vishwas , Gunesh Priya , Lodorfos George , Konstantopoulou Anastasia 
Published: September 2017

PurposeThe latest research in the field of employer branding highlights a mix of marketing principles and recruitment practices, based on the concept that, just as customers have perceptions of an organisation’s brand, then so do other stakeholders including employees. However, the emphasis has been on organisations, which predominantly operate in developed countries typically with Westernised-individualistic cultures. This paper aims to investigate employer branding for service organisations’ image and attraction as an employer in a non-Western culture.Design/methodology/approachThis study examines the perceptions of human resources’ professionals and practitioners on the role of employer branding in employer attractiveness and talent management, within Mauritian banking sector. The data collection for this qualitative study involved semi-structured interviews with senior managers from Mauritian banking organisations, including multinational enterprises, small business unit banks and Mauritian banks.FindingsAnalysis of the findings showed that organisations, and banks in this case, are increasingly competing to attract highly skilled personnel in various professional areas; therefore, those organisations that attract the best talent will have a distinct edge in the marketplace. Furthermore, findings from the semi-structured interviews with senior managers suggest that employer branding remains at the embryonic stage within the Mauritian banking sector; therefore, a clear need exists for a more developed strategy.Research limitations/implicationsThe outcomes of this study call for re-engineering with regards to managerial collaboration in organisations for the successful design and implementation of the employer branding strategy. The empirical findings from the Mauritian banking sector show that the strategic position occupied by the human resource function is still at an embryonic stage as regards with the competitiveness of banks as service organisations.Practical implicationsThe study presents a need for the development and maintenance of long-term collaborative and trust-based relationships between the human resource and marketing functions.Originality/valueThe insights provided through this study addresses the dearth of academic research on employer branding on the African continent while providing invaluable information from a human resource professional perspective.
Impact of customer orientation on turnover intention: mediating role of emotional labour
Authors: Wu Xue , Shie An-Jin , Gordon David 
Published: September 2017

PurposeThe purpose of this paper is to examine whether the frontline employees’ emotional labour can illustrate the relationship between customer orientation (CO) and turnover intention in the hospitality industry. The study applies the job demands and resources (JD-R) theory to explain the relationship between variables in the proposed model.Design/methodology/approachThe paper surveys a sample of 378 frontline employees in the hospitality industry.FindingsThe findings of this study show that the CO is strongly and positively associated with turnover intention. The three dimensions of emotional labour are all partially mediated with the relationship between CO and turnover intention.Research limitations/implicationsThe limitations of this study include the sample came from seven five-star hotels in Beijing, China. This study used perceptual self-reported measures, which may generate exaggerated relationships among variables. These issues are addressed in the analysis.Practical implicationsFirst, the recruitment and selection of frontline employees should incorporate an assessment of the level of CO. Second, hospitality management should train employees in the proper control of emotional labour.Social implicationsHospitality should make efforts to supply job resources, such as providing delicious food; more promotion opportunities; better training and recreation programs; more clarified job definitions; and position autonomy. Moreover, good interpersonal relationships, regular recreational activities and sharing working experiences with colleagues may be applied to cope with job demands.Originality/valueThis study is to explain the roles of the three dimensions of emotional labour (surface acting, genuine emotion and deep acting) in the relationship between CO and turnover intention. More specifically, this study demonstrates why hospitality employees with high (or low) CO have low (or high) levels of turnover intention applying the concept of emotional labour based on JD-R theory.
