An Implementation of Empirical Bayesian Inference and Non-Null Bootstrapping for Threshold Selection and Power Estimation in Multiple and Single Statistical Testing
Authors: Nasseroleslami Bahman 
Published: June 2018

AbstractThe majority of conclusions and interpretations in quantitative sciences such as neuroscience are based on statistical tests. However, the statistical inferences, especially in multivariate analyses, commonly rely on the p-values, but not on more expressive measures such as posterior probabilities, false discovery rates (FDR) and statistical power (1 − β). The aim of this report is to make these statistical measures further accessible in single and multiple statistical testing. For multiple testing, the Empirical Bayesian Inference (Efron et al., 2001; Efron, 2007) was implemented using non-parametric test statistics (e.g. the Area Under the Curve of the Receiving Operator Characteristics Curve or Spearman’s rank correlation) and Gaussian Mixture Model estimation of the probability density function of the original and bootstrapped data. For single statistical tests, the same test statistics were used to construct and estimate the null and non-null probability density functions using bootstrapping under null and non-null grouping assumptions. Simulations were used to test the reliability of the results under a wide range of conditions. The results show conformity to the real truth in the simulated conditions, which is held under various conditions imposed on the simulated data. The open-source MATLAB codes are provided and the utility of the approach has been exemplified and discussed for real-world electroencephalographic signals. This implementation of Empirical Bayesian Inference and informed selection of statistical thresholds are expected to facilitate more realistic scientific deductions in versatile fields, especially in neuroscience, neural signal analysis and neuro-imaging.

Published: June 2018

AbstractThe mechanisms initiating the late immune response to allografts are poorly understood. Through transcriptome analysis of serial protocol biopsies in kidney transplant recipients, we found a tight correlation between the initial response to kidney injury and a late B lymphocyte signature associated with renal dysfunction and fibrosis, suggesting a link between dysfunctional repair and immunoreactivity. To specifically investigate the immunological consequences of dysfunctional repair, we followed the mouse kidney up to 18 months after ischemia/reperfusion. Even in the absence of foreign antigens we identified a sustained immune response in conjunction with the transition to chronic kidney damage. This tissue-driven immunological process involved both the innate and the adaptive immune system and eventually induced an antigen-driven proliferation, selection and maturation of B lymphocytes into broadly-reacting antibody secreting cells. These findings reveal an unappreciated role of dysfunctional tissue repair on local immunoregulation with a particular relevance for late transplantation immunobiology.

Published: June 2018

AbstractResting state networks (RSNs) extracted from functional magnetic resonance imaging (fMRI) scans are believed to reflect the intrinsic organization and network structure of brain regions. Most traditional methods for computing RSNs typically assume these functional networks are static throughout the duration of a scan lasting 5–15 minutes. However, they are known to vary on timescales ranging from seconds to years; in addition, the dynamic properties of RSNs are affected in a wide variety of neurological disorders. Recently, there has been a proliferation of methods for characterizing RSN dynamics, yet it remains a challenge to extract reproducible time-resolved networks. In this paper, we develop a novel method based on dynamic mode decomposition (DMD) to extract networks from short windows of noisy, high-dimensional fMRI data, allowing RSNs from single scans to be resolved robustly at a temporal resolution of seconds. We demonstrate this method on data from 120 individuals from the Human Connectome Project and show that unsupervised clustering of DMD modes discovers RSNs at both the group (gDMD) and the single subject (sDMD) levels. The gDMD modes closely resemble canonical RSNs. Compared to established methods, sDMD modes capture individualized RSN structure that both better resembles the population RSN and better captures subject-level variation. We further leverage this time-resolved sDMD analysis to infer occupancy and transitions among RSNs with high reproducibility. This automated DMD-based method is a powerful tool to characterize spatial and temporal structures of RSNs in individual subjects.
Quality of management schools, strength of auditing and reporting standards and tax evasion
Authors: Khlif Hichem , Guidara Achraf 
Published: June 2018

Purpose
The purpose of this paper is to examine the relationship between the quality of management schools and tax evasion and tests whether the strength of auditing and reporting standards moderates such a relationship.

Design/methodology/approach
Tax evasion is measured using the macro-indirect approach based on Schneider, Buehn and Monterngro (2010). The quality of management schools is collected from The Global Competitiveness Report for 2014-2015.

Findings
On the basis of sample of 137 countries, the authors document that the level of tax evasion is negatively associated with the quality of management schools and the strength of auditing and reporting standards. When the authors distinguish between low- and high-strength of auditing and reporting standards countries, the authors find that the negative and significant association remains stable only for high-strength of auditing and reporting standards countries.

Practical implications
These results imply that the quality of management schools through its output (managers, fiscal controllers, auditors and businessmen) may increase the tendency of individuals in a given country to comply with tax rules and that legal enforcement may affect the ethical behaviours of these actors with regard to tax evasion.

Originality/value
The empirical findings have policy implications for governments with high levels of tax evasion since they highlight the importance of the quality of higher educational system in shaping tax compliance behaviour.
The link between perceived high-performance work practices, employee attitudes and service quality
Authors: Kloutsiniotis Panagiotis V. , Mihail Dimitrios M. 
Published: June 2018

PurposeThe purpose of this paper is to focus on the Greek banking sector and examine the indirect effects of high-performance work systems (HPWS) on service quality. Specifically, this study examines the effects of employees’ perceptions of HPWS on their trust toward their managers, as well as on service quality, through the mediating role of employee outcomes (measured by job satisfaction and affective commitment). In addition, trust is also tested for its role as a potential mediator and moderator in the relationship between HPWS and employee outcomes.Design/methodology/approachPartial least squares structural equation modeling was used on a sample of 350 front-line employees working in the Greek banking sector.FindingsThe findings showed that employee outcomes mediated the relationship between HPWS and service quality. On the other hand, although trust mediated the relationship between HPWS and employee outcomes, no support was found for its moderating effect. Finally, although not included in the initial analysis, trust was found to play a mediating and moderating role in the relationship between HPWS and service quality.Practical implicationsThis study highlights the vital role that a “trusting” work environment has to play on employee attitudes and outcomes. As this study shows, the positive employee behaviors along with their willingness to accept and support organizational goals influence their level of productivity.Originality/valueThis study sheds lights on the mediating and moderating role of trust in the relationship between HPWS, employee outcomes, and service quality. Finally, implications are drawn for organizations, managers, and practitioners.
Pakistani undergraduate students’ perceptions of project-based learning in the English composition course
Authors: Sultan Sameera , Javaid Syeda Tuba 
Published: June 2018

PurposeThe purpose of this paper is to explore how BS first-year students of the computer science department at a private university in Karachi perceive project-based learning (PjBL) implemented in the English composition course. The more specific objectives were to bring to light the benefits and challenges associated with PjBL from the students’ standpoint. Research works on students’ perceptions of project-based learning particularly in English language teaching remains an underresearched area in Pakistan and this makes this study useful and essential.Design/methodology/approachAdopting the lens of constructionism, this study used the qualitative approach for investigation. Thus, to achieve an in-depth insight into students’ perceptions, they were provided an opportunity to reflect and freely report their views regarding the project approach. The participants in this study formulate perceptions about a given phenomenon based on a thoughtful analysis of their experiences with that phenomenon. The qualitative researcher aims to get a deep understanding of these views of the participants, and so this study employed accounts and drawings as data collection tools. The data were then content analyzed.FindingsUpon data analysis, two major themes emerged being the benefits and challenges associated with PjBL. The benefits can be further divided into academic and non-academic benefits. The major academic benefit was that the project approach allowed students to achieve a deeper and more meaningful understanding of the subject matter whereas the non-academic benefits include enhanced communication and negotiation skills, time management, creative and critical thinking skills. The major challenges faced by the students were related to time management and getting along with each other in groups.Originality/valueThe research problem is a scarcely explored area in Pakistani English language teaching in higher education. Moreover, the use of student drawings as a data collection method is an unusual method for this research problem.

Published: June 2018

PurposeThe purpose of this paper is to look how the concepts of personal engagement (Kahn) and emotion in schools can aid understanding both of research priorities and practice in schools.Design/methodology/approachThis paper is a review of the area, so it has no particular methodological approach. Instead, it brings together engagement, emotion and capital.FindingsThis paper suggests that the commonalities between the areas discussed, and the relationship to professional capital can be enhanced both in research and practice.Research limitations/implicationsThis paper suggests that an emphasis on the positive side of personal engagement and emotion could lead to new insights in this area.Practical implicationsThis paper also suggests that personal engagement research has practical implications for teacher resilience and workplace relationships.Originality/valueOverall, this paper seeks to act as a catalyst for further discussion in the areas outlined, and asks the researcher to continue to draw together the practical and theoretical insights that can be gained through a focus on personal engagement.
Alternative careers at the first level of management
Authors: Kirchhoff Jörg W. , Karlsson Jan Ch. 
Published: June 2018

Purpose
First-line nurse managers are frequently torn between conflicting demands from management and employees, and previous research suggests that nurse managers use a variety of responses to cope with these demands. The purpose of this paper is to explore the influence of social support on nurse managers’ responses to role-conflict.

Design/methodology/approach
Two focused ethnographic studies involving participant observation and interviews with seven first-line nurse managers were completed. One study included first-line nurse managers from four units in two municipalities (2005), while the second included three first-line nurse managers from a hospital in Norway (2015-2016).

Findings
Three types of responses were identified: the embracing managerialism career, the emphasising managerialism career and the emphasising professionalism career. Emphasising managerialism was associated with role distance from the role of nurse, whereas emphasising professionalism involved role distance from the managerial role.

Originality/value
This study provides insights into first-line nurse managers’ responses to role conflict, by identifying the mechanisms involved and an opportunity to develop a theoretical framework for future studies among nurse managers.
Fake-love: brand love for counterfeits
Authors: Khandeparkar Kapil , Motiani Manoj 
Published: June 2018

Purpose
Recent studies have indicated that consumers who knowingly purchase counterfeits could be in love with the brands whose counterfeits they own. Arguably, this love may not be the same as the love felt by individuals who purchase the original brand. Research in this field has not studied how these two love types differ in its genesis and consequences. Therefore, the paper aims to discuss this issue and intends to fill this gap.

Design/methodology/approach
This study performed a multi-group analysis using (PLS-SEM) between two groups of customers (real-buyers and fake-buyers) to elucidate the factors that separate fake-love from real-love. This study adopted a combination of convenience sampling and field visits to identify 500 individuals who were classified as either real-buyers or fake-buyers.

Findings
The relationship between social-self and brand love is significantly stronger for fake-buyers as compared to real-buyers. However, the relationship between inner-self and brand love is significantly stronger in the case of real-buyers as compared to fake-buyers. Real-buyers tend to be more brand resilient than fake-buyers as their love emanates primarily from the inner-self. Additionally, fake-buyers indulge in +WOM more than real-buyers as their brand love emanates from the social-self.

Originality/value
This is the first study to explore the concept of brand love among consumers who purchase counterfeits in spite of being able to afford the original brands. This is also the first study that is focused on identifying the antecedents and outcomes that separate real-love from fake-love.
Library roles in advancing graduate peer-tutor agency and integrated academic literacies
Authors: McDaniel Sarah 
Published: June 2018

Purpose
This paper aims to apply integrated academic literacies and threshold concepts constructs to the development of graduate student literacies. Western Washington University has developed a graduate peer-tutors program to advance integrated academic literacies and graduate student agency. Graduate peer-tutors are expert-outsiders (Nowacek and Hughes, 2015): expert in conversations about literacies and outsiders to disciplinary expertise. Peer-tutors augment a support ecosystem that includes faculty advisors, subject librarians and others. Libraries should lead innovative programs to develop integrated literacies, and librarians should leverage both subject and literacies expertise as part of an ecosystem of support.

Design/methodology/approach
Drawing on library, writing center and higher education scholarship, the author draws on research methodologies from writing center scholarship to explore models for integrated graduate student literacies. The author collaborates with graduate peer-tutors to connect theory and practice in the Graduate Research & Writing Studio (GRWS).

Findings
Peer-tutor models offer a valuable layer of support for graduate students engaged in thesis-writing. Peer-tutors, faculty advisors and subject librarians play important roles in advancing development of integrated literacies. The role of peer-tutors is unique in advancing integrated literacies, and addressing affective barriers and equity concerns.

Practical implications
Economic pressures have transformed higher education, ushering new populations into graduate programs. Opportunities to enhance inclusivity cannot be realized without support for development of literacies. Libraries should lead with innovative services that address barriers to graduate student success.

Originality/value
The author leverages the unique laboratory offered by the GRWS and engages graduate peer-tutors in connecting scholarship and practice. Drawing on contemporary theoretical lenses on literacies, she argues for libraries’ leadership of programs that support integrated graduate student literacies.
Spatio-temporal analysis of trajectories for safer construction sites
Authors: Arslan Muhammad , Cruz Christophe , Roxin Ana-Maria , Ginhac Dominique 
Published: June 2018

Purpose
The purpose of this paper is to improve the safety of construction workers by understanding their behaviors on construction sites using spatio-temporal (ST) trajectories.

Design/methodology/approach
A review of construction safety management literature and international occupational health and safety statistics shows that the major reasons for fatalities on construction sites are mobility-related issues, such as unsafe human behaviors, difficult site conditions, and workers falling from heights and striking against or being struck by moving objects. Consequently, literature has been reviewed to find possible technological solutions to track the mobility of construction workers to reduce fatalities. This examination has suggested that location acquisition systems, such as Global Positioning System (GPS), have been widely used for real-time monitoring and tracking of workers on construction sites for hazard prevention. However, the raw data captured from GPS devices are generally available as discrete points and do not hold enough information to understand the workers’ mobility. As a solution, an application to transform raw GPS data into ST trajectories using different preprocessing algorithms is proposed for enhancing worker safety on construction sites.

Findings
The proposed system preprocesses raw GPS data for stay point detection, trajectory segmentation and intersection of multiple trajectories to find significant places and movements of workers on a construction site to enhance the information available to H&S managers for decision-making processes. In addition, it reduces the size of trajectory data for future analyses.

Originality/value
Application of location acquisition systems for construction safety management is very well addressed in the existing literature. However, a significant gap has been found: the usage of preprocessed ST trajectories is still missing in workers’ safety monitoring scenarios in the area of construction management. To address this research gap, the proposed system uses preprocessed ST trajectories to monitor workers’ movements on a construction site to identify potentially unsafe behaviors.
Grazing and resource availability control soil nematode body size and abundance–mass relationship in semi‐arid grassland
Authors: Andriuzzi Walter S. , Wall Diana H. 
Published: June 2018

Abstract

Body size is a central functional trait in ecological communities. Despite recognition of the importance of above ground–below ground interactions, effects of above‐ground herbivores on size and abundance–size relationships in soil fauna are almost uncharted. Depending on climate and soil properties, herbivores may increase basal resources of soil food webs, or reduce pore space, mechanisms expected to have contrasting effects on soil animal body size.

We investigated how body size and shape of soil nematodes responded to mammalian grazers in three semi‐arid grassland sites, along a gradient of soil texture and organic matter (OM) in a long‐term herbivore removal study. We analysed nematode mass, length, diameter, body size distribution and biomass distribution. We formulated two mechanistic hypotheses to assess whether resource availability or pore space was the dominant abiotic control and modulated the effects of grazing.

In ungrazed soils, average and maximum nematode size, as well as abundance and biomass of large nematodes, were greater in the high‐OM than in the low‐OM soil, and intermediate in the medium‐OM soil. Grazing promoted larger sizes in the low‐OM soil, where it had been shown to increase OM and microbial biomass, and led to more homogeneous average size and body size distribution across sites. The results support the hypothesis that nematode size was controlled by basal resource availability rather than by pore space. However, body shape might have been constrained by small pores in the fine‐texture, high‐OM soil, where nematodes were more elongated.

Grazing may facilitate larger sizes in soil nematode communities by boosting basal resources where these are limiting, with important implications for estimations of nematode biomass and contribution to carbon and nutrient cycling. These findings contribute to the insofar‐limited mechanistic understanding of how herbivores can shape functional traits of soil fauna and demonstrate that animals at one trophic level may control patterns in body size and abundance–size relationships in other trophic levels without a direct predator prey or competitive linkage between them.
Reproductive biology of Oreocereus fossulatus (Cactaceae), a long‐lived columnar cactus endemic to the tropical Andes
Authors: Larrea‐Alcázar Daniel M. , López Ramiro P. , Gutierrez Josseth P. , García Emilia 
Published: June 2018

AbstractThe geographic dichotomy hypothesis suggests that columnar cacti inhabiting the tropics depend on flower visitors (birds and bats) for their pollination, showing highly specialized animal‐pollinated systems. This pattern has been demonstrated for the northern hemisphere; however, our knowledge of the species of columnar cacti growing in the southern tropics is still scarce. In this study, we studied the reproductive biology of Oreocereus fossulatus (Cactaceae, Tribe Trichocereae), an endemic, columnar cactus of the tropical Andes, to determine if its pollination system tends to be more generalized (mixed systems of autogamy and xenogamy) than specialized (xenogamy) as a consequence of the geographic position of where it lives. Observations of the frequency of visits showed that Patagona gigas (Trochillidae) is its main pollinator. It visits the flowers when they are open, coinciding with the periods of greater floral reward (dusk and dawn of the first day of anthesis). The treatments of autogamy, xenogamy and geitonogamy produced fruits, showing that O. fossulatus exhibits a generalized pollination system, in the same way as its congeneric species O. celsianus, which is distributed farther south in the Prepuna biogeographical region. Our results suggest that species partially specializing in pollination by hummingbirds and, besides, capable of autopollination, could be common in the tropical and subtropical Andes, probably as a response to the unpredictable environments present in their ecosystems.
