Contribution of spatial heterogeneity in effective population sizes to the variance in pairwise measures of genetic differentiation
Authors: Prunier Jérôme G. , Dubut Vincent , Chikhi Lounès , Blanchet Simon 
Published: November 2015

SummaryPairwise measures of neutral genetic differentiation are supposed to contain information about past and on-going dispersal events and are thus often used as dependent variables in correlative analyses to elucidate how neutral genetic variation is affected by landscape connectivity. However, spatial heterogeneity in the intensity of genetic drift, stemming from variations in population sizes, may inflate variance in measures of genetic differentiation and lead to erroneous or incomplete interpretations in terms of connectivity. Here, we tested the efficiency of two distance-based metrics designed to capture the unique influence of spatial heterogeneity in local drift on genetic differentiation. These metrics are easily computed from estimates of effective population sizes or from environmental proxies for local carrying capacities, and allow us to introduce the hypothesis of Spatial-Heterogeneity-in-Effective-Population-Sizes (SHNe). SHNe can be tested in a way similar to isolation-by-distance or isolation-by-resistance within the classical landscape genetics hypothesis-testing framework.We used simulations under various models of population structure to investigate the reliability of these metrics to quantify the unique contribution of SHNe in explaining patterns of genetic differentiation. We then applied these metrics to an empirical genetic dataset obtained for a freshwater fish (Gobio occitaniae).Simulations showed that SHNe explained up to 60% of variance in genetic differentiation (measured asFst) in the absence of gene flow, and up to 20% when migration rates were as high as 0.10. Furthermore, one of the two metrics was particularly robust to uncertainty in the estimation of effective population sizes (or proxies for carrying capacity). In the empirical dataset, the effect of SHNe on spatial patterns ofFstwas five times higher than that of isolation-by-distance, uniquely contributing to 41% of variance in pairwiseFst. Taking the influence of SHNe into account also allowed decreasing the signal-to-noise ratio, and improving the upper estimate of effective dispersal distance.We conclude that the use of SHNe metrics in landscape genetics will substantially improve the understanding of evolutionary drivers of genetic variation, providing substantial information as to the actual drivers of patterns of genetic differentiation in addition to traditional measures of Euclidean distance or landscape resistance.
Essential precursors and effects of employee creativity in a service context
Authors: Shin Inyong , Hur Won-Moo , Oh Hongseok 
Published: November 2015

Purpose– The purpose of this paper is to examine how the emotional labor strategies of service employees differently influence the level of their creativity, and whether creative employees consequently benefit from that creativity in terms of achieving a high level of job performance.Design/methodology/approach– The authors surveyed flight attendants from an airline in South Korea. The authors distributed 150 questionnaires to flight attendants, received 126 responses, and finally obtained 119 usable data. The authors used Mplus 7.13 to evaluate validity and test the hypotheses.Findings– Whereas employees using deep acting were found to be less emotionally exhausted and more affectively committed toward their organization, which produced a high level of creativity, those who selected surface acting were shown to suffer more emotional exhaustion and have less affective commitment, which generated a low level of creativity. Customer service personnel behaving creatively resulted in superior official job performance appraisals.Originality/value– This study makes distinct contributions to the literature by proposing emotional labor as the key antecedent of employee creativity in service organizations, by confirming emotional exhaustion and affective commitment as the motivational mechanisms through which emotional labor strategies influence service employee creativity, and by suggesting the value of employee creativity.
Variety seeking by wine consumers in the southern states of the US
Authors: Olsen Janeen E. , Atkin Tom , Thach Liz , Cuellar Steve S. 
Published: November 2015

Purpose
– The purpose of this study is to investigate variety-seeking behavior among US wine consumers to determine if there are differences in their personal characteristics, values and relationship with wine.

Design/methodology/approach
– The research design uses a quantitative research study using data from an online survey of 401 US wine consumers. The Schwartz Value Inventory and the VARSEEK scale are used as measurement instruments. Data are analyzed using descriptive statistics, cluster analysis, ANOVA and discriminate analysis.

Findings
– The results illustrate strong differences between high variety-seeking consumers compared to moderate variety-seeking and variety avoiders. High variety seekers are younger, hold values favoring stimulation and tolerance of risk, pay more for wine, purchase wine in more locations, prefer more varietals and consider themselves more wine knowledgeable and involved than the other two segments.

Practical implications
– The results provide implications for wine marketers targeting high variety-seeking consumers, including offering wine brands with a wider array of varietals, wines from different countries, various price tiers and include creative packaging and sustainable messages in their presentation.

Originality/value
– This paper presents research addressing an important construct for wine marketers attempting to introduce new products and build brand loyalty.
Look for people, not for alpha: mutual funds success and managers intellectual capital
Authors: Naidenova Iuliia , Parshakov Petr , Zavertiaeva Marina , Tomé Eduardo 
Published: November 2015

Purpose
– This paper aims to explore whether individual intellectual capital of a fund manager allows mutual fund to outperform market.

Design/methodology/approach
– The sample includes 85 Russian equity funds for the period of 2013. First, Jensen’s alpha for each fund has been calculated, and then cross-sectional regression analysis has been used. While only a part of fund managers publish biographic sketches, the authors use the Heckman procedure to control for self-selection issues.

Findings
– The results support the idea that the individual characteristics indicate the possibility to earn abnormal alpha. Managers with economic education and with Moscow education perform better than others. Relationship between both fund performance measures and manager’s experience has inverted U-shape. Jensen’s alpha reaches its highest level at the point of 9 years, whereas beta – at 10 years of manager’s experience.

Research limitations/implications
– Investigation can be improved by including more variables that influence the disclosure of managers’ personal information, for example, by conducting surveys. Additionally, cross-sectional data restrict the analysis.

Practical implications
– The discovered characteristics of managers’ intellectual capital can be used as additional screening tool for the investor who is deciding on mutual fund choice in Russia. While individual intellectual capital is observable and more persistent in time in comparison with the past fund performance, such tool allows better decision-making.

Originality/value
– This is the first paper that explores which characteristics of Russian fund managers are connected with higher abnormal return (measured by Jensen’s alpha) and risk (beta) of mutual funds.
Toward a better understanding of MNEs’ local staffing decision: a multilevel analysis
Authors: Baik Youjin , Park Young-Ryeol 
Published: November 2015

Purpose– The purpose of this paper is to address the question of how regional diversification affects subsidiary staffing composition in multinational enterprises. Another important objective of this study is to examine the effects of institutional distance, specifically regulative and normative distances, on foreign subsidiary staffing composition.Design/methodology/approach– To estimate firm- and country-level parameters simultaneously, hierarchical linear modeling was conducted on a sample of 1,068 foreign subsidiaries of South Korean firms operating in 25 countries in 2014.Findings– The results reveal that intra-regional diversification has a positive effect, whereas inter-regional diversification has a negative effect on local staffing in foreign subsidiaries. In addition, there is a positive association between informal distance (such as normative distance) and local staffing of foreign subsidiaries, while formal distance (such as regulative distance) is negatively related to local staffing of foreign subsidiaries.Research limitations/implications– The cross-sectional nature of the data in this study may preclude examination of the relationships among institutional distance, institutional environment, and subsidiary staffing composition. The authors suggest that future researchers employ a longitudinal design to examine the effects on staffing composition of institutional distance and institutional environments over time.Originality/value– The paper contributes to the literature on international human resources management by highlighting the importance of combining multilevel parameters to improve assessment of the importance of firms’ competitive strategy and institutional environments in local staffing in foreign subsidiaries.

Authors: Amhed Suha Hassan , Abusin Rashida Mohamed Ahmed , Abdelgani Migdam Elsheikh , Babiker Abdel Gabar ELTayeb 
Published: November 2015

Purpose
– The purpose of this paper is to study the effects of the herbicide triclopyr, nitrogen and their combinations on Striga incidence and sorghum growth.

Design/methodology/approach
– A greenhouse study was undertaken in season 2013. Sorghum cv Wad Ahmed, urea and triclopyr were employed. Treatments were arranged in a randomized complete design with four replicates.

Findings
– Nitrogen alone suppressed the parasite completely early in the season. Triclopyr at 0.3 and 0.4 kg a.e. ha−1 reduced Striga emergence by 92.9 and 58.3 per cent early and late in the season, respectively. Triclopyr at 0.3 kg a.e. ha−1 applied subsequent to nitrogen at 43.8 kg ha−1 effected poor control of the parasite. Unrestricted Striga parasitism reduced sorghum height and chlorophyll content by 50.38 and 16.62 per cent, respectively. Triclopyr, nitrogen and their combination improved sorghum growth considerably.

Originality/value
– The results suggest that the herbicide when applied subsequent to nitrogen afforded the most consistent performance and resulted in the highest suppression of the parasite.

ABSTRACTMannan‐binding lectin (MBL), a circulating C‐type lectin, is an important member of the defense collagen family. It exhibits a high potential for recognizing broad categories of pathogen‐associated molecular patterns and initiating complement cascade responses. DCs are well‐known specialist antigen‐presenting cells that significantly trigger specific T cell‐mediated immune responses. In our previous study, it was observed that high concentrations of MBL significantly attenuate LPS‐induced maturation of monocyte‐derived DCs (MoDCs). In the current study, it was postulated that MBL at similar supraphysiological concentrations would affect early differentiation of MoDCs in some way. CD14+ monocytes from human peripheral blood mononuclear cells were cultured with granulocyte‐macrophage colony‐stimulating factor and IL‐4 in the presence or absence of physiological (1 µg/mL) and supraphysiological concentrations (20 µg/mL) of MBL protein, respectively. Phenotypic analysis indicated that the differentiated DCs incubated with high concentrations of MBL expressed MHC class II and costimulatory molecules (e.g., CD80 and CD40) more weakly than did control groups. The secretion of IL‐10 and IL‐6 increased markedly, whereas their mixed lymphocyte reaction‐stimulating capacity decreased. Members of the signal transducer and activator of transcription family were also found to be differentially regulated. Thus, beyond the role of MBL as an opsonin, our data reveal a possible inhibitory effect of MBL at high concentrations in monocyte‐DC transition, which probably provides one way of regulating adaptive immune responses by strict regulation of DCs, making MBL a better prospect for controlling relevant pathological events such as autoimmune diseases.
Cinema narrative therapy: utilizing family films to externalize children's ‘problems’
Authors: Turns Brie , Macey Porter 
Published: November 2015

Parents frequently bring children to therapy with the notion that their child has a ‘problem’. Children can begin to internalize these labels and negative attributes created by others. This article introduces a method for marriage and family therapists to integrate cinematherapy and narrative techniques. The method provided is to be utilized after a family has viewed a film chosen conjointly by the family and the therapist. This article includes suggestions as to how the family can externalize the movie character's problem, instances when the character defeats the problem and the qualities the character demonstrates while overcoming the problem. A case example has been included demonstrating the effectiveness of the method and clinical implications for future application.Practitioner points

Watching movies has become a popular pastime for many families, so client compliance is likely.
There are numerous situations that would allow this method to be utilized with the family unit, such as ‘problem’ children, grief and loss and childhood anxiety.
Therapists should consider keeping lists of appropriate films that accommodate clients' culture and ethnicity.
Filtering with a drill pump: an efficient method to collect suspended sediment
Authors: Kelso Julia E. , Baker Michelle A. 
Published: November 2015

AbstractWater quality monitoring programs across multiple disciplines use total suspended solids (TSS), and volatile suspended solids (VSS), to assess potential impairments of surface water and groundwater. While previous methods for instream filtering have been developed, the need for rapid, cost‐effective, high volume sampling has increased with the need to verify and supplement data produced by sondes and instantaneous data loggers. We present an efficient method to filter water instream with a portable drill pump that results in reduced sample processing time, and potentially reduced error associated with sample transportation, preservation, contamination, and homogenization. This technical note outlines the advantages of filtering instream vs. in the laboratory. It also compares TSS and VSS concentrations filtered with a drill pump vs. standard filtration methods with a vacuum pump as outlined by USEPA methods 160.2 and 160.4. Samples were collected at 4 sites and filtered in the field, or transported to the laboratory and filtered within 12 or 24 h of collection. Overall TSS and VSS samples filtered instream with a drill pump vs. in the laboratory produced similar concentrations with a similar range in variability for each method. Sample filtering with a drill pump decreased processing time by five minutes per sample.

Published: November 2015

AbstractDespite their size, small farm ponds are important features in many landscapes. Yet hydrographical databases often fail to capture these ponds, and their impacts on watershed processes remain unclear. For a 230‐km2 portion of central Texas, United States (U.S.), we created a historical inventory of ponds and quantified the accuracy of automated detection methods under varying drought conditions. In addition, we documented pond dredging/enlargement events and identified sites that had been abandoned. We also analyzed sediment cores from downstream reservoirs to track changes in watershed sediment transport. Over 75 years, pond densities increased more than 350% — to among the highest documented in the U.S. — and the ability of automated methods to detect these ponds was highly dependent on drought severity (R2 = 0.96). Approximately 5% of ponds present in the 1950s were no longer present in 2012, while 33% were dredged between 1937 and 2012. Downstream reservoir sedimentation has decreased by an average of 55% as ponds have increased in number. These findings suggest that small ponds and the maintenance of trapping efficiency have large‐scale impacts on sediment dynamics. Accurately accounting for these storage effects is vital to water resource planning efforts.
Crowdsourced geometric morphometrics enable rapid large‐scale collection and analysis of phenotypic data
Authors: Chang Jonathan , Alfaro Michael E. 
Published: November 2015

SummaryAdvances in genomics and informatics have enabled the production of large phylogenetic trees. However, the ability to collect large phenotypic data sets has not kept pace.Here, we present a method to quickly and accurately gather morphometric data using crowdsourced image‐based landmarking.We find that crowdsourced workers perform similarly to experienced morphologists on the same digitization tasks. We also demonstrate the speed and accuracy of our method on seven families of ray‐finned fishes (Actinopterygii).Crowdsourcing will enable the collection of morphological data across vast radiations of organisms and can facilitate richer inference on the macroevolutionary processes that shape phenotypic diversity across the tree of life.
