Authors: Shahzad Syed Jawad Hussain , Kanwal Memoona , Ahmed Tanveer , Ur Rehman Mobeen 
Published: November 2016

PurposeThe assessment of interdependence between stock markets is an important aspect of international portfolio management. The purpose of this paper is to examine and highlight the diversification potential of South Asian stock marketsvis-à-visdeveloped and European stock markets.Design/methodology/approachThe developed stocks markets include USA and UK, and South Asian stock markets include India, Pakistan and Sri Lanka while DJ STOXX 600 index is used to represent the European stock markets. Monthly data are used to examine long-run relationship through ARDL bound testing approach and estimates are obtained using DLOS. Short-term dynamics are captured through vector error correction-based Granger causality.FindingsSouth Asian stock markets are closely linked with each other; similarly, developed/European markets are interlinked. US stock market not only impacts European stock markets, it also Granger cause South Asian stock markets. The findings suggest increase in comovement of South Asian stock markets with the global markets after financial crises of 2007-2008.Practical implicationsThe diversification benefits of South Asian stock markets for international investors are still evident due to their low relationship (in both long and short run) with developed/European stock markets.Originality/valueGiven the emergence of South Asian stock markets, new insight on their relationship with developed stock markets can provide interesting findings for international portfolio diversification. The South Asian equity markets are an important source of investment because of their immense growth and weak correlation with international markets.
Global cities, work and family collectivism and work-family conflict in India
Authors: Shah Grishma , Rajadhyaksha Ujvala 
Published: November 2016

PurposeThe authors observe the impact of certain aspects of globalization on the work-family interface in India. Specifically, the purpose of this paper is to investigate the impact of life in Tier 1 (more globalized) vs Tier 2 (less globalized) cities, family/work collectivism and gender on work-family conflict (WFC) – both work interfering with family (WIF) conflict as well as family interfering with work (FIW) conflict.Design/methodology/approachThe study surveyed 628 young employees on cultural values of collectivism and WFC.FindingsResults suggest a main effect of tier in which Tier 1 city individuals experience more of both forms of WFC than Tier 2 city individuals. However, two- and three-way interactions between family/work collectivism and tier greatly moderate the main effect. Interactions indicate that family collectivism decreased WIF more for Tier 1 as compared to Tier 2 cities and work collectivism decreased FIW more for Tier 2 as compared to Tier 1 cities. The results suggest that high family collectivism creates high conflict for those who are low on work collectivism and high family collectivism creates low conflict for those who are high on work collectivism.Research limitations/implicationsThe paper provides great insight into globalization and WFC within the context of cultural values. The paper calls for further studies on globalization, work life enrichment and cultural values.Practical implicationsThe results build a case for more paid and organizationally supported interventions for work-life balance in India.Originality/valueLarge scale institutional changes, such as globalization, call for a reexamination of cultural dynamics. This study heeds the call and examines WFC in the context of rapid economic and social transformation occurring in India by bridging globalization, cultural change and WIF/FIW.
Dispositional traits influence on mentoring relationships
Authors: Arora Ridhi , Rangnekar Santosh 
Published: November 2016

PurposeThe purpose of this paper is to investigate the role of personality factors in influencing mentoring relationships in the South-Asian context.Design/methodology/approachThe sample included 363 subjects from public and private sector organizations in North India.FindingsResults revealed that in the Indian context, conscientiousness acts as significant predictor of perceived psychosocial mentoring, agreeableness acts as significant predictor of perceived career mentoring support, and emotional stability acts as significant predictor of both categories of mentoring relationships. Further, managers employed in public sector organizations were found to be high on all the Big Five personality factors and mentoring functions in contrast to managers from private sector organizations.Research limitations/implicationsOverall, the results suggest that mentoring relationships should operate in organizations with a firm understanding of employees’ personality traits. Implications and future research directions were also discussed. Further, suggestions have also been given for incorporating various interventions in order to handle employees with different personality attributes such as counseling for helping emotionally unstable employees manage their emotions and stress.Originality/valueTo the knowledge, this is the first study that seeks to examine impact of personality factors on mentoring relationships in the South-Asian context.
Investment-cash flow sensitivity and financial constraints: evidence from Pakistan
Authors: Riaz Yasir , Shahab Yasir , Bibi Robina , Zeb Shumaila 
Published: November 2016

Purpose
The purpose of this paper is to provide new insights about investment-cash flow sensitivities (ICFS) as a representative of financial constraints, by examining panel data consisting of 288 listed firms in Pakistan.

Design/methodology/approach
This study uses a panel data methodology and first difference generalized method of moments to control the problems of heterogeneity and endogeneity. By five different criteria, estimations are made for full and pre-classified sub-samples. Sargan test and Arellano-Bond serial correlation statistic are used for identification and validation of instruments and model.

Findings
According to the results, the ICFS has increased monotonically with the level of financial constraints. Further, the results depict that ICFS for the constrained group is much higher as compared to the unconstrained group. Overall, the result illustrates positively significant ICFS.

Practical implications
This study confirms signs of imperfections in the capital market, which leads to financial markets inaccessibility preceded by high under-investment costs and low social and economic development. Thus, proper policy designing and instigation are necessary for the subsidies, taxation, and foreign direct investment and later for financial market development and promotion of private corporate investment.

Originality/value
Previous studies have mostly focused on developed countries where large listed companies work in well-developed financial markets and do not face severe financial constraints because of the greater market integration (Bekaert et al., 2011, 2013) and superior investor protection laws (Djankov et al., 2008; La porta et al., 1998). However, this study focuses on listed companies from the emerging Pakistani market, which will bring forth the interesting aspects of ICFS and will enhance the existing literature effectively.
Evaluating the influence of social media on brand sacralization
Authors: Das Payel , Mandal Santanu 
Published: November 2016

Purpose
The purpose of this paper is to reveal the influence of social media in the development of brand sacralization in young consumers in emerging Asian market. Brand sacralization is the phenomenon where consumers (especially young) become an adherent of brands and consider brands as sacred entities. The paper specifically explores the influence of social media interaction and social media usability on brand sacralization and consequently its influence on online purchase intention (PI) and brand loyalty.

Design/methodology/approach
Perceptual responses were gathered from 232 undergraduate and postgraduate students (age: 17-27 years) studying in an Indian private university and is subsequently analyzed using structural equation modeling. The young population is chosen as the target sample as they possess majority stake in final product purchase decision nowadays and also contribute as a dominant consumer category in online market places.

Findings
The researcher found a strong positive influence of social media interaction and social media usability on brand sacralization. Further, brand sacralization is found to have a positive and significant influence on online PI and brand loyalty of young consumers. However, social media interaction does not contribute significantly to usability of social media. The researcher has also found a significant influence of brand loyalty on online PI for these young shoppers.

Originality/value
The study is the foremost to investigate the influence of social media in developing brand sacralization and its influence on online PI and brand loyalty. Further the study is the first to develop a measurement instrument for brand sacralization. The study is the foremost in developing measures for social media interaction and social media usability.
Root isoflavonoids and hairy root transformation influence key bacterial taxa in the soybean rhizosphere
Authors: White Laura J. , Ge Xijin , Brözel Volker S. , Subramanian Senthil 
Published: November 2016

SummaryRhizodeposits play a key role in shaping rhizosphere microbial communities. In soybean, isoflavonoids are a key rhizodeposit component that aid in plant defense and enable symbiotic associations with rhizobia. However, it is uncertain if and how they influence rhizosphere microbial communities. Isoflavonoid biosynthesis was silenced via RNA interference of isoflavone synthase in soybean hairy root composite plants. Rhizosphere soil fractions tightly associated with roots were isolated, and PCR amplicons from 16S rRNA gene variable regions V1–V3 and V3–V5 from these fractions were sequenced using 454. The resulting data was resolved using MOTHUR and vegan to identify bacterial taxa and evaluate changes in rhizosphere bacterial communities. The soybean rhizosphere was enriched in Proteobacteria and Bacteroidetes, and had relatively lower levels of Actinobacteria and Acidobacteria compared with bulk soil. Isoflavonoids had a small effect on bacterial community structure, and in particular on the abundance of Xanthomonads and Comamonads. The effect of hairy root transformation on rhizosphere bacterial communities was largely similar to untransformed plant roots with approximately 74% of the bacterial families displaying similar colonization underscoring the suitability of this technique to evaluate the influence of plant roots on rhizosphere bacterial communities. However, hairy root transformation had notable influence on Sphingomonads and Acidobacteria.
Glycerol stress in Saccharomyces cerevisiae: Cellular responses and evolved adaptations
Authors: Mattenberger Florian , Sabater‐Muñoz Beatriz , Hallsworth John E. , Fares Mario A. 
Published: November 2016

SummaryGlycerol synthesis is key to central metabolism and stress biology in Saccharomyces cerevisiae, yet the cellular adjustments needed to respond and adapt to glycerol stress are little understood. Here, we determined impacts of acute and chronic exposures to glycerol stress in S. cerevisiae. Glycerol stress can result from an increase of glycerol concentration in the medium due to the S. cerevisiae fermenting activity or other metabolic activities. Acute glycerol‐stress led to a 50% decline in growth rate and altered transcription of more than 40% of genes. The increased genetic diversity in S. cerevisiae population, which had evolved in the standard nutrient medium for hundreds of generations, led to an increase in growth rate and altered transcriptome when such population was transferred to stressful media containing a high concentration of glycerol; 0.41 M (0.990 water activity). Evolution of S. cerevisiae populations during a 10‐day period in the glycerol‐containing medium led to transcriptome changes and readjustments to improve control of glycerol flux across the membrane, regulation of cell cycle, and more robust stress response; and a remarkable increase of growth rate under glycerol stress. Most of the observed regulatory changes arose in duplicated genes. These findings elucidate the physiological mechanisms, which underlie glycerol‐stress response, and longer‐term adaptations, in S. cerevisiae; they also have implications for enigmatic aspects of the ecology of this otherwise well‐characterized yeast.

SummaryMany plant‐associated fungi host endosymbiotic endobacteria with reduced genomes. While endobacteria play important roles in these tri‐partite plant–fungal–endobacterial systems, the active physiology of fungal endobacteria has not been characterized extensively by systems biology approaches. Here, we use integrated proteomics and metabolomics to characterize the relationship between the endobacterium Mycoavidus sp. and the root‐associated fungus Mortierella elongata. In nitrogen‐poor media, M. elongata had decreased growth but hosted a large and growing endobacterial population. The active endobacterium likely extracted malate from the fungal host as the primary carbon substrate for energy production and biosynthesis of phospho‐sugars, nucleobases, peptidoglycan and some amino acids. The endobacterium obtained nitrogen by importing a variety of nitrogen‐containing compounds. Further, nitrogen limitation significantly perturbed the carbon and nitrogen flows in the fungal metabolic network. M. elongata regulated many pathways by concordant changes on enzyme abundances, post‐translational modifications, reactant concentrations and allosteric effectors. Such multimodal regulations may be a general mechanism for metabolic modulation.
Fire modifies the phylogenetic structure of soil bacterial co‐occurrence networks

Published: November 2016

SummaryFire alters ecosystems by changing the composition and community structure of soil microbes. The phylogenetic structure of a community provides clues about its main assembling mechanisms. While environmental filtering tends to reduce the community phylogenetic diversity by selecting for functionally (and hence phylogenetically) similar species, processes like competitive exclusion by limiting similarity tend to increase it by preventing the coexistence of functionally (and phylogenetically) similar species. We used co‐occurrence networks to detect co‐presence (bacteria that co‐occur) or exclusion (bacteria that do not co‐occur) links indicative of the ecological interactions structuring the community. We propose that inspecting the phylogenetic structure of co‐presence or exclusion links allows to detect the main processes simultaneously assembling the community. We monitored a soil bacterial community after an experimental fire and found that fire altered its composition, richness and phylogenetic diversity. Both co‐presence and exclusion links were more phylogenetically related than expected by chance. We interpret such a phylogenetic clustering in co‐presence links as a result of environmental filtering, while that in exclusion links reflects competitive exclusion by limiting similarity. This suggests that environmental filtering and limiting similarity operate simultaneously to assemble soil bacterial communities, widening the traditional view that only environmental filtering structures bacterial communities.
Composition and diversity of mucosa‐associated microbiota along the entire length of the pig gastrointestinal tract; dietary influences

Published: November 2016

SummaryMucosa‐associated microbial populations of the gastrointestinal tract are in intimate contact with the outer mucus layer. This proximity offers these populations a higher potential, than lumenal microbiota, in exerting effects on the host. Functional characteristics of the microbiota and influences of host‐physiology shape the composition and activity of the mucosa‐associated bacterial community. We have shown previously that inclusion of an artificial sweetener, SUCRAM, included in the diet of weaning piglets modulates the composition of lumenal‐residing gut microbiota and reduces weaning‐related gastrointestinal disorders. In this study, using Illumina sequencing we characterised the mucosa‐associated microbiota along the length of the intestine of piglets, and determined the effect of SUCRAM supplementation on mucosa‐associated populations. There were clear distinctions in the composition of mucosa‐associated microbiota, between small and large intestine, concordant with differences in regional oxygen distribution and nutrient provision by the host. There were significant differences in the composition of mucosa‐associated compared with lumenal microbiota in pig caecum. Dietary supplementation with SUCRAM affected mucosa‐associated bacterial community structure along the length of the intestinal tract. Most notably, there was a substantial reduction in predominantCampylobacterpopulations proposing that SUCRAM supplementation of swine diet has potential for reducing meat contamination and promoting food safety.

SummarySunlight can be directly harvested by photoheterotrophic bacteria to create a pH gradient across the membrane, which can then be utilized to produce ATP. Despite the potential importance of this trophic strategy, when and where such organisms are found in the seas and oceans is poorly described. Here, we describe the abundance and taxonomy of bacteria with different trophic strategies (heterotrophs, phototrophs and photoheterotrophs) in contrasting water masses of the ultra‐oligotrophic eastern Mediterranean Sea. These water bodies, an anticyclonic eddy and a high‐chlorophyll patch resulting from transport of nutrient‐rich coastal waters into offshore oligotrophic waters, each supported different microbial populations in surface waters. Based on infrared microscopy and metagenomics, aerobic anoxygenic photoheterotrophic (AAP) bacteria represented up to 10.4% of the microbial community. In contrast, the proteorhodopsin (PR) gene was found in 78.6%–118.8% of the bacterial genome equivalents, the highest abundance reported to date. These results suggest that PR‐mediated photoheterotrophy may be especially important in oligotrophic, potentially phosphate‐limited conditions.
Assembling activity/setting participation with disabled young people

Published: November 2016

AbstractRehabilitation research investigating activity participation has been largely conducted in a realist tradition that under‐theorises the relationship between persons, technologies, and socio‐material places. In this Canadian study we used a post‐critical approach to explore activity/setting participation with 19 young people aged 14 to 23 years with complex communication and/or mobility impairments. Methods included integrated photo‐elicitation, interviews, and participant observations of community‐based activities. We present our results using the conceptual lens of assemblages to surface how different combinations of bodies, social meanings, and technologies enabled or constrained particular activities. Assemblages were analysed in terms of how they organised what was possible and practical for participants and their families in different contexts. The results illuminate how young people negotiated activity needs and desires in particular ‘spacings’ each with its own material, temporal, and social constraints and affordances. The focus on assemblages provides a dynamic analysis of how dis/abilities are enacted in and across geotemporal spaces, and avoids a reductive focus on evaluating the accessibility of static environmental features. In doing so the study reveals possible ‘lines of flight’ for healthcare, rehabilitation, and social care practices.
Microstructural organization of the central nervous system in the harvestman Leiobunum japonicum (Arachnida: Opiliones)
Authors: Park Yong‐Ki , Moon Myung‐Jin 
Published: November 2016

AbstractAlthough the order Opiliones constitutes the third‐largest group of arachnids, this creature is still mysterious and has a rich unexplored field compared to what is known about insects and crustaceans. The order Opiliones is traditionally regarded as a close relative of mites, mainly because of morphological similarities in external body structure; however microstructural organization of the ganglionic neurons and nerves in the harvestman Leiobunum japonicum is quite similar to the central nervous system (CNS) in all extant arachnids. The CNS consists of a large neural cluster with paired appendicular nerves. The esophagus passes through the neural cluster and divides it into the upper supraesophageal ganglion (SpG) and the lower subesophageal ganglion (SbG). The dorsal part of the SpG has a quite condensed cell body compared with other parts of the CNS and has two main components, the protocerebrum and the cheliceral ganglion. The protocerebrum receives the optic nerves and has four main groups of neuropiles from the optic lobes, the superior central body, the lateral neuropils (corpora pedunculata) and the inferior neuropil. However, a pair of pedipalpal and four pairs of appendage nerves including several pairs of abdominal nerves arise from the nerve masses of the SbG.
Text and metatext in the resource‐based view
Authors: Barney Jay B. , Mackey Alison 
Published: November 2016

AbstractThis paper distinguishes between text and metatext in the resource‐based view (RBV) – that is, the actual words and logic fundamental to the RBV (the text) and the traditions, interpretations and applications of the theory (the metatext). It argues that Kaufman's () criticism of the RBV as applied to strategic human resource management actually focuses on RBV metatext and not text. Indeed, unlike some RBV metatext, RBV text actually has a great deal to say about research and practice in strategic human resource management.
The summary‐likelihood method and its implementation in the Infusion package

Published: November 2016

AbstractIn recent years, simulation methods such as approximate Bayesian computation have extensively been used to infer parameters of population genetic models where the likelihood is intractable. We describe an alternative approach, summary likelihood, that provides a likelihood‐based analysis of the information retained in the summary statistics whose distribution is simulated. We provide an automated implementation as a standard R package,Infusion, and we test the method, in particular for a scenario of inference of population‐size change from genetic data. We show that the method provides confidence intervals with controlled coverage independently of a prior distribution on parameters, in contrast to approximate Bayesian computation. We expect the method to be applicable for at least six‐parameter models and discuss possible modifications for higher‐dimensional inference problems.
