Published: November 2018

ABSTRACTOxytocin(OT) has effects in both human behavior and in the brain, which is not limited in the specific brain area but also with the potential effect on connectivity with other brain regions. Evidence indicate that the effects of OT on human behavior are multifaceted, such as trust behavior, decrease anxiety, empathy and bonding behavior. Since the vital role of mentalizing in understanding others, here we proposed and tested that whether OT has a general effect on theory of mind brain network which is associated to the effect of related social behavioral and personality traits. Used a randomized, double-blind placebo-controlled group design, we investigated the resting-state functional magnetic resonance imaging after intranasal OT or placebo. The functional connectivity (FC) maps with seed in left temporoparietal junction (lTPJ) and right TPJ showed that OT significantly increased connectivity between rTPJ and default attention network (DAN), while decreased the FC between lTPJ and medial prefrontal network (MPN). With implementing machine learning approach, we further reported satisfactory classification accuracy that Identified altered FCs of TPJ can classify OT and PL group. Moreover, individual’s empathy trait can modulate the FC between left TPJ and right RECT, which was positively correlated with empathic concern in PL group whereas lTPJ-rRECT negatively correlated in OT group. These results demonstrate that OT has significant effect on FC with lTPJ and rTPJ, brain regions critical for mentalizing, and the empathy concern can modulate the FC. These findings add to our understanding of the neural mechanisms by which OT modulates social behaviors, especially in social interaction involving mentalizing.

SummaryOne of the major challenges for plant scientists is increasing wheat (Triticum aestivum) yield potential (YP). A significant bottleneck for increasing YP is achieving increased biomass through optimization of Radiation Use Efficiency (RUE) along the crop cycle. Exotic material such as landraces and synthetic wheat has been incorporated into breeding programs in an attempt to alleviate this, however their contribution to YP is still unclear. To understand the genetic basis of biomass accumulation and RUE we applied genome-wide association study (GWAS) to a panel of 150 elite spring wheat genotypes including many landrace and synthetically derived lines. The panel was evaluated for 31traits over two years under optimal growing conditions and genotyped using the 35K Wheat Breeders array. Marker-trait-association identified 94 SNPs significantly associated with yield, agronomic and phenology related traits along with RUE and biomass at various growth stages that explained 7–17 % of phenotypic variation. Common SNP markers were identified for grain yield, final biomass and RUE on chromosomes 5A and 7A. Additionally we show that landrace and synthetic derivative lines showed higher thousand grain weight (TGW), biomass and RUE but lower grain number (GNO) and harvest index (HI). Our work demonstrates the use of exotic material as a valuable resource to increase YP. It also provides markers for use in marker assisted breeding to systematically increase biomass, RUE and TGW and avoid the TGW/GNO and BM/HI trade-off. Thus, achieving greater genetic gains in elite germplasm while also highlighting genomic regions and candidate genes for further study.

AbstractThe Lesser Antilles, in the Eastern Caribbean, were long considered to have only two species in the genusIguanaLaurenti 1768: the Lesser Antillean iguanaIguana delicatissima, which is endemic to parts of the Lesser Antilles, and the common green iguanaIguana iguana, which also occurs throughout Central and South America. However, herpetologists and reptile collectors have pointed out strong physical differences between some of the island populations ofIguana iguanaand those from the continent. Drawing on both morphological and genetic data, this paper describes a third speciesIguana insularissp. nov. from the southern Lesser Antilles, specifically the countries of Saint Lucia, St Vincent & the Grenadines, and Grenada. The new species is described based on the following unique combination of characters: Presence of high median and medium to small lateral horns on the snout; Small subtympanic plate not exceeding 20% of the eardrum size; Two or three scales of decreasing size anterior to the subtympanic plate; Fewer than ten small to medium triangular gular spikes; Medium sized dewlap; Low number of small to medium dispersed nuchal tubercles; Dark brown iris, with the white of the eye visible; Oval, prominent nostril; Short and relatively flat head; High dorsal spines; No swelling of the jowls in reproductively active males; Colour of head, body and tail changing from green to pale grey or creamy white in old adults; Vertical black stripes on body and tail, fading with age in some populations. This paper furthermore distinguishes two subspecies:Iguana insularis insularisfrom the Grenada Bank (comprising Grenada and the Grenadine islands), andIguana insularis sanctaluciaefrom Saint Lucia. The form on the island of Saint Vincent has not been identified. Both subspecies are globally threatened by unsustainable hunting (including the pet trade) and by invasive alien species, including hybridization from invasive iguanas from South and Central America (I. iguanaandI. rhinolopha, considered here as full species) that have become established in all three countries. The authors call for stronger measures to conserve the remaining purebredIguana insularissp. nov. throughout its range and for further research to identify other cryptic species and subspecies ofIguanain the Lesser Antilles.

AbstractStrains ofSaccharomyces cerevisiaeused to make beer, bread and wine are genetically and phenotypically distinct from wild populations associated with trees. The origins of these domesticated populations are not always clear; human-associated migration and admixture with wild populations have had a strong impact onS. cerevisiaepopulation structure. We examined the population genetic history of beer strains and find that ale strains and theS. cerevisiaeportion of allotetraploid lager strains were derived from admixture between populations closely related to European grape wine strains and Asian rice wine strains. Similar to both lager and baking strains, ale strains are polyploid, providing them with a passive means of remaining isolated from other populations and providing us with a living relic of their ancestral hybridization. To reconstruct their polyploid origin we phased the genomes of two ale strains and found ale haplotypes to both be recombinants between European and Asian alleles and to also contain novel alleles derived from extinct or as yet uncharacterized populations. We conclude that modern beer strains are the product of a historical melting pot of fermentation technology.
Evolution of ovipositor length inDrosophila suzukiiis driven by enhanced cell size expansion and anisotropic tissue reorganization

Published: November 2018

AbstractMorphological diversity is dominated by variation in body proportion. Yet the cellular processes underlying differential growth of morphological traits between species remain largely unknown. Here we compare the ovipositors of two closely related species,Drosophila melanogasterandD. suzukii.D. suzukiihas switched its egg-laying niche from rotting to ripe fruit. Along with this shift, theD. suzukiiovipositor has undergone a significant change in size and shape. Using an allometric approach we find that, while adult ovipositor width has hardly changed between the species,D. suzukiiovipositor length is almost double that ofD. melanogaster. We show that this size difference mostly arises during a 6-hour time window in the middle of pupal development. We observe that the developing ovipositors of the two species comprise an almost identical number of cells, with a very similar profile of cell shapes and orientations. After cell division stops, we find that the ovipositor area continues to grow through the isotropic expansion of cell apical area. Remarkably, at one point, the rate of cell apical area expansion is more than 4 times faster inD. suzukiithan inD. melanogaster. In addition, we find that an anisotropic cellular reorganization of the developing ovipositor results in a net elongation of the tissue, despite the isotropic expansion of cell size, and is enhanced inD. suzukii. Therefore, the quantitative fine-tuning of shared, morphogenetic processes -the rate of cell size expansion and the cellular rearrangements–can drive macroscopic evolutionary changes in organ size and shape.

AbstractBackgroundLarge animal models, such as the dog, are increasingly being used over rodent models for studying naturally occurring diseases including gastrointestinal (GI) disorders. Dogs share similar environmental, genomic, anatomical, and intestinal physiologic features with humans. To bridge the gap between currently used animal models (e.g. mouse) and humans, and expand the translational potential of the dog model, we developed a three dimensional (3D) canine GI organoid (enteroid and colonoid) system. Organoids have recently gained interest in translational research as this model system better recapitulates the physiological and molecular features of the tissue environment in comparison with two-dimensional cultures.ResultsOrganoids were propagated from isolation of adult intestinal stem cells (ISC) from whole jejunal tissue as well as endoscopically obtained duodenal, ileal and colonic biopsy samples of healthy dogs and GI cases, including inflammatory bowel disease (IBD) and intestinal carcinomas. Intestinal organoids were comprehensively characterized using histology, immunohistochemistry, RNA in situ hybridization and transmission electron microscopy, and organoids mimicked the in vivo tissue environment. Physiological relevance of the enteroid system was defined using functional assays such as Optical Metabolic Imaging (OMI), the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) function assay, and Exosome-Like Vesicles (EV) uptake assay, as a basis for wider applications of this technology in basic, preclinical and translational GI research.ConclusionsIn summary, our findings establish the canine GI organoid systems as a novel model to study naturally occurring intestinal diseases in dogs and humans. Furthermore, canine organoid systems will help to elucidate host-pathogen interactions contributing to GI disease pathogenesis.

Published: November 2018

PurposeThe purpose of this paper is to estimate the effects of human resource management (HRM) practices on firm outcomes at the firm level in Vietnam.Design/methodology/approachThe paper employs a fixed-effects framework for the estimation using a panel sample of manufacturing firms from small- and medium-sized enterprise surveys between 2009 and 2013.FindingsThe paper finds that, on average, a firm that provides the training for new workers gains roughly 13.7, 10 and 14.9 percent higher in output value per worker, value added per worker and gross profit per worker, respectively, than the counterpart. Moreover, an additional ten-day training duration for new employees on average leads to a 4.1 percent increase in output value per worker, a 3.0 percent rise in value added per worker and a 3.0 percent growth in gross profit per worker. The paper also uncovers that a marginal 10 percent of HRM spending results in about 2 and 1.6 percent rises in output value per worker and value added per worker, respectively.Originality/valueUsing the case of Vietnam, this paper shows the important roles of HRM practices in explaining firm outcomes.
Make, buy, borrow or crowdsource? The evolution and future of outsourcing
Authors: Malhotra Naresh K. , Uslay Can 
Published: November 2018

Purpose
The purpose of this paper is to provide a conceptual and historical overview of the evolution of outsourcing. The authors then focus and prognosticate on the future of outsourcing and develop several compelling ideas based on extant insights and the rule of three axioms.

Design/methodology/approach
The insights are developed based on a review of the extant literature and evolution of trends.

Findings
The paper generates several insights. First, there is a need to carefully differentiate between core and non-core functions when deciding on whether/what to outsource. Some outsourcing options may boost financial performance in the short run but undermine the long-term viability of the firm. Public firms outsource more than private firms after controlling for size. In many cases, the optimal number of primary suppliers for a critical function/process/stock keeping unit (SKU) is three (while also allowing for a number of secondary suppliers). The optimal share distribution between the suppliers for the same SKU is rank ordinal (i.e. not equal). The complexity and the maturity of the supply chain as well as industry life cycle, regulation and technology influence the optimal number of primary suppliers.

Research limitations/implications
The insights have significant implications for outsourcing decisions and for improving their impact on firm performance. The emergence of the shared economy, subscription-based business models and crowdsourcing will lead to consumers, business and society that increasingly borrows rather than one that makes or buys.

Originality/value
The paper represents the first attempt to integrate the axioms of the rule of three with the outsourcing literature and the theory of the firm. It emphasizes the need to align (long-term) performance objectives with managerial incentives as businesses manage their outsourcing efforts.
Self-control today, indulgence tomorrow? How judgment bias and temporal distance influence self-control decisions
Authors: Ladeira Wagner Junior , Oliveira Santini Fernando , Costa Pinto Diego , Araujo Clécio Falcao , Fleury Fernando A. 
Published: November 2018

Purpose
This paper aims to analyze how judgment bias (optimism vs pessimism) and temporal distance influence self-control decisions. This research also analyzes the mediating role of perceived control on judgment bias and temporal distance.

Design/methodology/approach
Three studies (one laboratory and two online experiments) analyze how judgment bias and temporal distance influence self-control decisions on consumers’ willingness to pay.

Findings
The findings uncover an important boundary condition of temporal distance on self-control decisions. In contrast to previous research, the findings indicate that individuals exposed to optimism (vs pessimism) bias display more self-control in the future and make choices that are more indulgent in the present. The findings also reveal that perceived control mediates the effects of judgment bias and temporal distance.

Practical implications
The findings help managers to adapt short- and long-term marketing efforts, based on consumers’ momentary judgment biases and on their chronic judgment bias orientation.

Originality/value
This research contributes to the literature on self-control and temporal distance, showing that judgment bias reverses previous research findings on self-control decisions.
Knowledge transfer in IS offshoring: a Delphi study of the offshore coordinator role
Authors: Strasser Artur , Westner Markus , Strahringer Susanne 
Published: November 2018

Purpose
This paper aims to investigate the main tasks, necessary skills, and the implementation of the offshore coordinator’s role to facilitate knowledge transfer in information systems (IS) offshoring.

Design/methodology/approach
This empirical exploratory study uses the classical Delphi method that includes one qualitative and two quantitative rounds to collect data on IS experts’ perceptions to seek a consensus among them.

Findings
The participants agreed, with strong consensus, for a set of 16 tasks and 15 skills. The tasks focused primarily on relationship management and facilitating knowledge transfer on different levels. The set of skills consists of approximately 25 per cent “hard” skills, e.g. professional language skills and project management skills, and approximately 75 per cent “soft” skills, e.g. interpersonal and communication skills and the ability to deal with conflict. Two factors mainly influence implementing the offshore coordinator role: project size and the number of projects to be supported simultaneously.

Practical implications
The findings provide indications of how to define and fulfill this crucial role in practice to facilitate the knowledge transfer process in a positive way.

Originality/value
Similarities in previous research findings are aggregated to examine the intermediate role in detail from a consolidated perspective. This results in the first comprehensive set of critical tasks and skills assigned to the competency dimensions of the universal competency framework, demonstrating which and how many competency dimensions are critical.

PurposeCustomer-to-customer (C2C) interaction plays a significant role in service. The purpose of this paper is to identify the drivers that motivate customers to interact with other customers, the interactions through which customers affect other customers and the value outcomes of C2C interactions for the participants.Design/methodology/approachThe paper is based on a systematic literature review of C2C interactions. The authors analyzed 142 peer-reviewed articles to synthesize existing knowledge about C2C interactions. A generic value framework is used to categorize earlier research and reveal areas for further research.FindingsThe main outcome of this study is an integrative framework of C2C interaction that bridges C2C interactions and customer value. The findings indicate customer-, firm- and situation-induced drivers of C2C interactions. Outcome- and process-focused C2C interactions are identified to result in functional, emotional and social value outcomes. Avenues for additional research to explore issues related to current technology-saturated service settings are proposed.Research limitations/implicationsThe paper proposes an agenda for future research to extend the C2C interaction research domain and explore how such interactions create value for the customer. The role of the service provider is not explicitly addressed but is an important area for further research.Practical implicationsCompanies can use the framework to understand how they can become involved in and support beneficial C2C interaction.Originality/valueThis paper reviews empirical studies on C2C interaction, offering a systematic review of C2C interaction and producing an integrative framework of C2C interaction.

The determinants of job satisfaction in the Egyptian labor market
Authors: Ezzat Asmaa , Ehab Maye 
Published: November 2018

Purpose
This paper aims to analyze the determinants on job satisfaction in the Egyptian labor market, using Egypt’s Labor Market Panel Survey (ELMPS), the wave of 2012.

Design/methodology/approach
Several determinants are analyzed including the wage level, the paid and sick leaves, the medical and social insurance, job stability among other individual and job characteristics. To this end, an ordered logit model is estimated to assess the significance of these different variables as determinants for job satisfaction.

Findings
The empirical findings indicate that wages and stability are major determinants for job satisfaction for the sample of wage workers. However, the results change according to gender; the hourly wage level affects men’s level of job satisfaction, while it does not affect that of females. Furthermore, the job satisfaction of women is determined more by the job characteristics rather than the monetary compensation.

Social implications
The empirical findings shed light on the importance of formalizing jobs, as it has an effect on the level of job satisfaction of both women and men.

Originality/value
To the best of the authors’ knowledge, this is the first paper to examine the determinants of job satisfaction for wage workers in Egypt using the ELMPS data.
A geography of residents' worry about the disruptive effects of contaminated sites
Authors: Prior Jason Hugh , Gorman‐Murray Andrew , McIntyre Erica , Connon Irena , Adams Jon , Madden Ben 
Published: November 2018

AbstractWhile the links between contaminated sites and adverse effects on human health and well‐being are being increasingly recognised, some argue that the magnitude of the health problem is inadequately addressed because it is largely invisible. Health geographies literature has sought to highlight this invisibility by focusing on the link between contaminated sites and health. This study adds to health geographies by presenting unique insights into the geography of residents' worry about the disruptive effect of environmental contamination on health and well‐being. It analyses a sample of residents (n = 485) living near 13 contaminated sites across Australia. Ordinal logistic regression analysis of closed‐format survey questions was combined with coding of open‐ended survey questions to reveal the geography of residents' worry about contamination from nearby sites. First, the study explores some of the main relationships between residents, their environs, and contaminants from nearby source sites, which determines their levels of worry: residents' demographics, residents' proximity to sites, contaminant boundaries and borders, and type of contaminant. Second, the study investigates how worry affects residents' health and well‐being, ranging from effects on their personal functioning through to their sense of ontological security, which depends in part upon their perceptions of contaminants' impacts. Despite having identified a range of diverse and negative effects of worry about contamination on residents, we found that worry for contamination can also prompt coping strategies and problem‐solving, reinforcing the need for more research on this subject.
