A new method in designing group chain acceptance sampling plans (GChSP) for generalized exponential distribution
Authors: Pawan Teh Mohd Azri , Aziz Nazrina , Zain Zakiyah 
Published: October 2020

PurposeThis paper introduces group chain acceptance sampling plans (GChSP) for a truncated life test at preassumed time by using the minimum angle method. The proposed method is an approach, where both risks associated with acceptance sampling, namely consumers’ and producer’s risks, are considered. Currently, the GChSP only considers the consumer's risk (CR), which means the current plan only protects the consumer not the producer since it does not take into account the producer's risk (PR) at all.Design/methodology/approachThere are six phases involved when designing the GChSP, which are (1) identifying the design parameters, (2) implementing the operating procedures, (3) deriving the probability of lot acceptance, (4) deriving the probability of zero or one defective, (5) deriving the proportion defective and (6) measuring the performance.FindingsThe findings show that the optimal number of groups obtained satisfies both parties, i.e. consumer and producer, compared to the established GChSP, where the number of group calculated only satisfies the consumer not the producer.Research limitations/implicationsThere are three limitations identified for this paper. The first limitation is the distribution, in which this paper only proposes the GChSP for generalized exponential distribution. It can be extended to different distribution available in the literature. The second limitation is that the paper uses binomial distribution when deriving the probability of lot acceptance. Also, it can be derived by using different distributions such as weighted binomial distribution, Poisson distribution and weighted Poisson distribution. The final limitation is that the paper adopts the mean as a quality parameter. For the quality parameter, researchers have other options such as the median and the percentile.Practical implicationsThe proposed GChSP should provide an alternative for the industrial practitioners and for the inspection activity, as they have more options of the sampling plans before they finally decide to select one.Originality/valueThis is the first paper to propose the minimum angle method for the GChSP, where both risks, CR and PR, are considered. The GChSP has been developed since 2015, but all the researchers only considered the CR in their papers.

The impact of a sense of virtual community on online community: does online privacy concern matter?
Authors: Kim Jihye , Kim Hyung-Min , Kim Minseong 
Published: October 2020

PurposeThe purpose of this study is to investigate the structural relationships between a sense of virtual community (SOVC), community satisfaction, community involvement, community commitment and alternative attractiveness in the online fan community context.Design/methodology/approachThis study gathered and empirically analyzed data from 277 members of the online Super Junior fan community with frequency, reliability, confirmatory factor analyses and structural equation modeling (SEM) with Statistical Package for the Social Sciences (SPSS) 20.0 and AMOS 24.0.FindingsThe findings of SEM indicated that community satisfaction was significantly influenced by the four dimensions of SOVC, while community involvement was significantly affected by membership and fulfillment of needs. Also, community commitment and alternative attractiveness were significantly impacted by community satisfaction and community involvement. Lastly, privacy concern moderated the paths from influence to community satisfaction and from community satisfaction to community commitment, respectively.Practical implicationsThe findings of this study should help online fan community administrators to reduce members' perception of alternative attractiveness (other fan communities) and to understand how privacy concern influences members' attitudes toward the online community.Originality/valueIn light of the findings, a greater understanding of the determinants of community commitment and alternative attractiveness along with privacy concern is critical in retaining virtual fan communities' members over the long-term.
The importance of appraisal in stressor–well-being relationships and the examination of personality traits as boundary conditions
Authors: Smith Rachel Williamson , DeNunzio Michael M. , Haynes Nicholas J. , Thiele Aneeqa 
Published: October 2020

PurposeThe purpose of this study was to examine the mediating role of appraisals in three stressor–well-being relationships: (1) the mediating role of challenge appraisals in the relationship between daily skill demands and daily work engagement, (2) the mediating role of hindrance appraisals in the relationship between daily interruptions and daily depletion and (3) the mediating role of threat appraisals in the relationship between daily emotional demands and daily anxiety. We also examined the moderating influence of conscientiousness on the daily skill demands–challenge appraisal relationship, the moderating role of extraversion on the daily interruptions–hindrance appraisal relationship and the moderating influence of neuroticism on the daily emotional demands–threat appraisal relationship. Supplemental analyses also examined the moderating influence of the aforementioned personality traits on the respective direct effects of stressors on well-being outcomes.Design/methodology/approachWe tested our hypotheses using a 5-days experience sampling design in a sample of 114 working adults and employed multilevel modeling.FindingsAll hypothesized mediating mechanisms were supported, however, the majority of moderation hypotheses were not supported.Originality/valueWe sought to extend the relatively recent advancement in the challenge–hindrance framework to provide additional evidence of the utility of distinguishing between challenge, hindrance and threat stressors. Although not supported, this is the one of the first papers to test the moderating influence of personality traits on the stressor–appraisal relationship.
Institutional duality incidence on subsidiaries: configuration, differentiation and avoidance strategies
Authors: Ahworegba Akiebe Humphrey , Estay Christophe , Garri Myropi 
Published: October 2020

PurposeTo illustrate how threats of institutional duality (ID) incidence subsidiaries confront are converted to opportunities, by conceptualizing how subsidiaries attain operational legitimacy at both their headquarters (HQs) and host countries.Design/methodology/approachUsing a systematic literature review, the authors build on institutional theories by analyzing the ID literature along its structure, main processes and outcomes. The authors configure frameworks of both HQ control systems and host countries' institutional threats, showing how subsidiaries contingently navigate across them using configuration, differentiation and avoidance strategies.FindingsThe authors’ findings show that “foresighted” subsidiaries attain operational legitimacy through configuration, differentiation and avoidance of threats incidental to ID, by strategizing along certain formal and informal institutional variables including legal, sociocultural and technical factors.Originality/valueThe authors propose “structural configuration of ID incidence” and “subsidiary path to legitimacy” frameworks. The former configures how the interaction between HQ and host countries' variables constitute ID incidence threats. The latter highlights how “foresighted” subsidiaries use configuration, differentiation and avoidance strategies to attain operational legitimacy.
NFL team revenue distribution and revenue sharing: a median voter theorem
Authors: Ehrlich Justin , Ghimire Shankar , Sanders Shane 
Published: October 2020

PurposeRevenue sharing is ubiquitous among North American professional sports leagues. Under pool revenue sharing, above-average revenue teams of a league effectively transfer revenues to below-average revenue teams. Herein, the authors find and prove that a league will vote into policy a pool revenue sharing arrangement if and only if mean team revenue is greater than presharing median revenue, where this condition is equivalent to the presence of positive nonparametric skewness in a league’s distribution of team revenues. This represents a median voter theorem for league revenue sharing.Design/methodology/approachThe authors consider the case of revenue sharing for the National Football League (NFL), a league that pools and equally shares national revenues among member teams.FindingsThe authors find evidence of positive and significant nonparametric skewness in NFL team revenue distributions for the 2004–2016 seasons. This distribution is observed amid annual majority rule votes of League owners in favor of maintaining the incumbent pool revenue sharing model (as opposed to no team revenue sharing). Distribution of revenues – namely the existence of outlying large market NFL teams – appears to consistently explain the historical popularity of NFL revenue sharing.Originality/valueThe median voter theorem uncovered in the case of NFL applies to all professional sports leagues and can be used predictively as well as descriptively.

AbstractAssociational resistance theory predicts that insect herbivory decreases with increasing tree diversity in forest ecosystems. However, the generality of this effect and its underlying mechanisms are still debated, particularly since evidence has accumulated that climate may influence the direction and strength of the relationship between diversity and herbivory.We quantified insect leaf herbivory and leaf chemical defences (phenolic compounds) of silver birchBetula pendulain pure and mixed plots with different tree species composition across 12 tree diversity experiments in different climates. We investigated whether the effects of neighbouring tree species diversity on insect herbivory in birch, that is, associational effects, were dependent on the climatic context, and whether neighbour‐induced changes in birch chemical defences were involved in associational resistance to insect herbivory.We showed that herbivory on birch decreased with tree species richness (i.e. associational resistance) in colder environments but that this relationship faded as mean annual temperature increased.Birch leaf chemical defences increased with tree species richness but decreased with the phylogenetic distinctiveness of birch from its neighbours, particularly in warmer and more humid environments.Herbivory was negatively correlated with leaf chemical defences, particularly when birch was associated with closely related species. The interactive effect of tree diversity and climate on herbivory was partially mediated by changes in leaf chemical defences.Our findings confirm that tree species diversity can modify the leaf chemistry of a focal species, hence its quality for herbivores. They further stress that such neighbour‐induced changes are dependent on climate and that tree diversity effects on insect herbivory are partially mediated by these neighbour‐induced changes in chemical defences.A freePlain Language Summarycan be found within the Supporting Information of this article.
Genetic variation in resistance and high fecundity impede viral biocontrol of invasive fish
Authors: Mintram Kate S. , van Oosterhout Cock , Lighten Jackie 
Published: October 2020

Abstract

Common carp Cyprinus carpio is one of the top global invasive vertebrates and can cause significant ecological damage. The Australian Government's National Carp Control Program (NCCP) proposes to release Koi herpesvirus (KHV) to eradicate feral carp in one of the largest ecological interventions ever attempted. Ecological and human health risks have been highlighted regarding the release of a highly pathogenic viral biocontrol for an aquatic species. The efficacy of KHV has also been questioned, and it has not been demonstrated to produce lasting population reductions.

We developed an individual‐based model (IBM) to examine the ecological and evolutionary response of a carp population after KHV release. This simulated the interaction between fish life history, viral epidemiology, host genetic resistance and population demography to critically evaluate the impact of KHV release under optimal conditions and a ‘best‐case scenario’ for disease transmission.

KHV will rarely result in prolonged reductions or population extinctions. Crucially, realistic scenarios result in a rapidly rebounding population of resistant individuals. Additional measures aimed to reduce carp population recovery rate (e.g. with genetic engineering) require rapid efficacy to significantly reduce carp numbers alongside KHV.

Fish fecundity has an overwhelming influence on viral efficacy as a biocontrol agent when combined with genetic resistance within a population. A high probability of population extinction is only met when carp fecundity is reduced to 1% of biological observations.

Synthesis and applications. We use an individual‐based model to evaluate the efficacy of Koi herpesvirus biocontrol in Common Carp, and find that high host fecundity combined with genetic resistance results in rapid population rebound after initial large fish kills. Biocontrol approaches relying on natural selection lose efficacy over successive generations as resistance genes increase in frequency. Given the intense logistical effort and risks to ecosystems and human health associated with large fish kills after viral release, we suggest that sustained manual removal, alongside ecological restoration to favour recovery of native species, provides a risk‐free approach to reducing populations.
Common garden experiments to study local adaptation need to account for population structure
Authors: de Villemereuil Pierre , Gaggiotti Oscar E. , Goudet Jérôme 
Published: October 2020

Abstract

Common garden experiments are precious to study adaptive phenomenon and adaptive potential, in that they allow to study local adaptation without the confounding effect of phenotypic plasticity. The QST − FST comparison framework, comparing genetic differentiation at the phenotypic and molecular level, is the usual way to test and measure whether local adaptation influences phenotypic divergence between populations.

Here, we highlight that the assumptions behind the expected equality QST = FST under neutrality correspond to a very simple model of population genetics. While the equality might, on average, be robust to violation of such assumptions, more complex population structure can generate strong evolutionary noise.

Synthesis. We highlight recent methodological developments aimed at overcoming this issue and at providing a more general framework to detect local adaptation, using less restrictive assumptions. We invite empiricists to look into these methods and theorists to continue developing even more general methods.
Evidence‐based juvenile justice programs and practices: A critical review
Authors: Elliott Delbert S. , Buckley Pamela R. , Gottfredson Denise C. , Hawkins J. David , Tolan Patrick H. 
Published: October 2020

AbstractThere is growing critical commentary and debate about the relative effectiveness of individual program and generic practice approaches to identifying evidence‐based interventions and their impact on the operation of the juvenile justice system. The central issue is whether both of these approaches to identifying evidence‐based interventions provide a valid and reliable guide to improving juvenile justice programming and, if so, what are the relative advantages and disadvantages of each? From a public policy perspective, should we be investing more heavily in one or the other, or treating them as effective complementary approaches and encourage both? We address each of these questions and offer some suggestions for improving the effectiveness of each approach.

AbstractEutrophication, harmful algal blooms, and human health impacts are critical environmental challenges resulting from excess nitrogen and phosphorus in surface waters. Yet we have limited information regarding how wetland characteristics mediate water quality across watershed scales. We developed a large, novel set of spatial variables characterizing hydrological flowpaths from wetlands to streams, that is, “wetland hydrological transport variables,” to explore how wetlands statistically explain the variability in total nitrogen (TN) and total phosphorus (TP) concentrations across the Upper Mississippi River Basin (UMRB) in the United States. We found that wetland flowpath variables improved landscape‐to‐aquatic nutrient multilinear regression models (from R2 = 0.89 to 0.91 for TN; R2 = 0.53 to 0.84 for TP) and provided insights into potential processes governing how wetlands influence watershed‐scale TN and TP concentrations. Specifically, flowpath variables describing flow‐attenuating environments, for example, subsurface transport compared to overland flowpaths, were related to lower TN and TP concentrations. Frequent hydrological connections from wetlands to streams were also linked to low TP concentrations, which likely suggests a nutrient source limitation in some areas of the UMRB. Consideration of wetland flowpaths could inform management and conservation activities designed to reduce nutrient export to downstream waters.
Rapture‐ready darters: Choice of reference genome and genotyping method (whole‐genome or sequence capture) influence population genomic inference in Etheostoma

Published: October 2020

AbstractResearchers studying nonmodel organisms have an increasing number of methods available for generating genomic data. However, the applicability of different methods across species, as well as the effect of reference genome choice on population genomic inference, remain difficult to predict in many cases. We evaluated the impact of data type (whole‐genome vs. reduced representation) and reference genome choice on data quality and on population genomic and phylogenomic inference across several species of darters (subfamily Etheostomatinae), a highly diverse radiation of freshwater fish. We generated a high‐quality reference genome and developed a hybrid RADseq/sequence capture (Rapture) protocol for the Arkansas darter (Etheostoma cragini). Rapture data from 1,900 individuals spanning four darter species showed recovery of most loci across darter species at high depth and consistent estimates of heterozygosity regardless of reference genome choice. Loci with baits spanning both sides of the restriction enzyme cut site performed especially well across species. For low‐coverage whole‐genome data, choice of reference genome affected read depth and inferred heterozygosity. For similar amounts of sequence data, Rapture performed better at identifying fine‐scale genetic structure compared to whole‐genome sequencing. Rapture loci also recovered an accurate phylogeny for the study species and demonstrated high phylogenetic informativeness across the evolutionary history of the genus Etheostoma. Low cost and high cross‐species effectiveness regardless of reference genome suggest that Rapture and similar sequence capture methods may be worthwhile choices for studies of diverse species radiations.

AbstractPlant interactions are as important belowground as aboveground. Belowground plant interactions are however inherently difficult to quantify, as roots of different species are difficult to disentangle. Although for a couple of decades molecular techniques have been successfully applied to quantify root abundance, root identification and quantification in multispecies plant communities remains particularly challenging. Here we present a novel methodology, multispecies genotyping by sequencing (msGBS), as a next step to tackle this challenge. First, a multispecies meta‐reference database containing thousands of gDNA clusters per species is created from GBS derived High Throughput Sequencing (HTS) reads. Second, GBS derived HTS reads from multispecies root samples are mapped to this meta‐reference which, after a filter procedure to increase the taxonomic resolution, allows the parallel quantification of multiple species. The msGBS signal of 111 mock‐mixture root samples, with up to 8 plant species per sample, was used to calculate the within‐species abundance. Optional subsequent calibration yielded the across‐species abundance. The within‐ and across‐species abundances highly correlated (R2 range 0.72–0.94 and 0.85–0.98, respectively) to the biomass‐based species abundance. Compared to a qPCR based method which was previously used to analyse the same set of samples, msGBS provided similar results. Additional data on 11 congener species groups within 105 natural field root samples showed high taxonomic resolution of the method. msGBS is highly scalable in terms of sensitivity and species numbers within samples, which is a major advantage compared to the qPCR method and advances our tools to reveal hidden belowground interactions.
