Three-Dimensional Binocular Eye-Hand Coordination in Normal Vision and with Simulated Visual Impairment
Authors: Maiello Guido , Kwon MiYoung , Bex Peter J. 
Published: December 2017

AbstractSensorimotor coupling in healthy humans is demonstrated by the higher accuracy of visually tracking intrinsically-rather than extrinsically-generated hand movements in the fronto-parallel plane. It is unknown whether this coupling also facilitates vergence eye movements for tracking objects in depth, or can overcome symmetric or asymmetric binocular visual impairments. Human observers were therefore asked to track with their gaze a target moving horizontally or in depth. The movement of the target was either directly controlled by the observer's hand or followed hand movements executed by the observer in a previous trial. Visual impairments were simulated by blurring stimuli independently in each eye. Accuracy was higher for self-generated movements in all conditions, demonstrating that motor signals are employed by the oculomotor system to improve the accuracy of vergence as well as horizontal eye movements. Asymmetric monocular blur affected horizontal tracking less than symmetric binocular blur, but impaired tracking in depth as much as binocular blur. There was a critical blur level up to which pursuit and vergence eye movements maintained tracking accuracy independent of blur level. Hand-eye coordination may therefore help compensate for functional deficits associated with eye disease and may be employed to augment visual impairment rehabilitation.
On Negative Heritability and Negative Estimates of Heritability
Authors: Steinsaltz David , Dahl Andy , Wachter Kenneth W. 
Published: December 2017

AbstractWe consider the problem of interpreting negative maximum likelihood estimates of heritability that sometimes arise from popular statistical models of additive genetic variation. These may result from random noise acting on estimates of genuinely positive heritability, but we argue that they may also arise from misspecification of the standard additive mechanism that is supposed to justify the statistical procedure. Researchers should be open to the possibility that negative heritability estimates could reflect a real physical feature of the biological process from which the data were sampled.

Published: December 2017

AbstractThe development of the human brain and nervous system can be affected by genetic or environmental factors. Here we focus on characterizing the genetic perturbations that accompany and may contribute to neurodevelopmental phenotypes. Specifically, we examine two types of structural variants, namely, copy number variation and balanced chromosome rearrangements, discovered in subjects with neurodevelopmental disorders and related phenotypes. We find that a feature uniting these types of genetic aberrations is a proximity to ultraconserved elements (UCEs), which are sequences that are perfectly conserved between the reference genomes of distantly related species. In particular, while UCEs are generally depleted from copy number variant regions in healthy individuals, they are, on the whole, enriched in genomic regions disrupted by copy number variants or breakpoints of balanced rearrangements in affected individuals. Additionally, while genes associated with neurodevelopmental disorders are enriched in UCEs, this does not account for the excess of UCEs either in copy number variants or close to the breakpoints of balanced rearrangements in affected individuals. Indeed, our data are consistent with some manifestations of neurodevelopmental disorders resulting from a disruption of genome integrity in the vicinity of UCEs.
A Quantitative Assessment of Prefrontal Cortex in Humans Relative to Nonhuman Primates
Authors: Donahue Chad J , Glasser Matthew F , Preuss Todd M , Rilling James K , Van Essen David C 
Published: December 2017

AbstractHumans have the largest cerebral cortex among primates. A long-standing controversy is whether association cortex, particularly prefrontal cortex (PFC), is disproportionately larger in humans compared to nonhuman primates, as some studies report that human PFC is relatively expanded whereas others report uniform PFC scaling. We address this controversy using MRI-derived cortical surfaces of many individual humans, chimpanzees, and macaques. We present two parcellation-based PFC delineations based on cytoarchitecture and function and show that a previously used morphological surrogate (cortex anterior to the genu of the corpus callosum) substantially underestimates PFC extent, especially in humans. We find that the proportion of cortical gray matter occupied by PFC in humans is up to 86% larger than in macaques and 24% larger than in chimpanzees. The disparity is even greater for PFC white matter volume, which is 140% larger in humans compared to macaques and 71% larger than in chimpanzees.
The impact of financial restatement on auditor changes: Iranian evidence
Authors: Eshagniya Azam , Salehi Mahdi 
Published: December 2017

Purpose
This paper aims to examine the effect of financial restatement on changing the auditor in the following years.

Design/methodology/approach
The study uses data of 105 companies (735 company-years) listed on the Tehran Stock Exchange collected during the period 2008-2014. Logistic regression is used to test the hypotheses.

Findings
The results of hypotheses present that restatement does not cause auditor changes and that as the severity of a restatement increases, the auditor change in the following year of restatement also does not increase. Restating companies having strong governance do not go for auditor changes as compared with other companies. In addition, in companies that are restating, non-big auditor changes are not more likely than a big auditor. Also, in companies restating simultaneous with a CEO turnover, there is no possibility of auditor change. Furthermore, multinomial logistic regression showed that the adjustments resulting from the correction of errors and changes in procedures and the amount of adjustments do not cause auditor change in the following year. So, the results have shown that the restatement is not an important factor in changing auditor the next year.

Originality/value
The current study analyses the impact of financial restatement on auditor changes in a deep manner in a developing country like Iran.
Analysis of the impact of referral-based recruitment on job attitudes and turnover in temporary agency workers
Authors: González Luis , Rivarés Lorenzo 
Published: December 2017

PurposeThe purpose of this paper is to analyse the referral-based recruitment process in temporary work agencies (TWA) and its influence on workers’ attitudes and turnover.Design/methodology/approachBy means of a quasi-experimental design with equivalent groups and repeated measures, differences in attitudes -group commitment, task commitment, group satisfaction, general job satisfaction and job involvement- and turnover in a group of workers recruited by the TWA through the “bring a friend” procedure based on employee referrals and in another group comprising workers not recruited through employee referrals are studied.FindingsThe results obtained show that workers recruited through employee referrals by the TWA are characterized by having greater group commitment, task commitment, task satisfaction, general job satisfaction and turnover than employees not recruited through employee referrals. These differences are explained on the basis of expectations and the feeling of obligation generated in the recruitment process.Research limitations/implicationsThe sample size is an element to take into account when valuing the obtained results. Moreover, the effects of the recruitment programs with employee referral on the TWA should be analyze on more qualified jobs. Furthermore, they should be also evaluated if the effects on the attitudes stay the same in longer periods.Originality/valueThis is the first paper to examine the impact of the employee-referral-based recruitment method known as “bring a friend” on attitudes – group commitment, task commitment, group satisfaction, general job satisfaction, and job involvement – and turnover of employees when used by TWA. Likewise, we want highlight the fact that this is a longitudinal research study.
Absorptive capacity, cluster linkages, and innovation
Authors: Chandrashekar Deepak , Mungila Hillemane Bala Subrahmanya 
Published: December 2017

Purpose
The purpose of this paper is to outline the key determinants of innovation performance of a firm in a cluster. This paper probes the role of absorptive capacity in furthering the cluster linkages and thereby enhancing the innovation performance of a firm.

Design/methodology/approach
This study adopts stratified random sampling technique to choose sample firms from the identified population of firms in a cluster. Further, it employs primary data collection method to collect data from sample firms through a semi-structured questionnaire based in-depth interviews with the top level management of sample firms. It uses multiple linear regression (MLR) techniques to ascertain the influence of absorptive capacity on degree of cluster linkages (both intra-cluster and extra-cluster linkages), and degree of cluster linkages (both intra-cluster and extra-cluster linkages) on innovation performance of a firm.

Findings
On the one hand, internal factors of absorptive capacity of a firm have a significant positive influence on the degrees of both intra-cluster linkages and extra-cluster linkages. On the other hand, external factors of absorptive capacity of a firm significantly impact the degree of intra-cluster linkages (DICL). But, they have no significant influence on the degree of extra-cluster linkages (DECL). Further, both the DICL and the DECL drive innovation performance of a firm in a cluster. Notably, subsidiaries of externally based firms exhibit superior innovation performance compared to those firms based in a cluster.

Originality/value
This paper contributes to the extant literature in two ways. First, it empirically validates the effect of absorptive capacity of a firm on its degree of cluster linkages (both intra-cluster and extra-cluster linkages) taking into account both internal and external factors of absorptive capacity. Second, it ascertains the influence of degree of cluster linkages (both intra-cluster and extra-cluster linkages) on the innovation performance of a firm in a cluster.
What happened to Çaction?
Authors: Letiche Hugo 
Published: December 2017

Purpose
Although the epistemology of researcher reflexivity has been championed as crucial to research for some 30 years, it remains controversial and often ill-defined. In the 1980s, “reflexivity” was championed by the hermeneutically and epistemologically savvy to try and break the strangle hold of naïve positivism. Nowadays, reflexivity most often refers to the turn-to-affect and to the researcher’s ability and willingness to radically sensitivize “self” to others and circumstances. The purpose of this paper is to specify what non-representational research has brought to the reflexivity debate and then focus on Brosseau’s particular rendition of reflexivity, which is seen as far more demanding, problematic and valuable.

Design/methodology/approach
The approach followed in this paper is a hermeneutic reflection based on Thrift’s and Brosseau’s oeuvres. The perspective is historical, qua research methods’ take on reflexivity and qua Brosseau textual production.

Findings
Five differences between Thrift’s and Brosseau’s reflexivities are highlighted. Brosseau brings us much further in applying affective reflexivity to research writing than does Thrift.

Originality/value
A polemic calling for and warnings about the complexities of affective reflexivity, presented as demanding, dangerous and complex.

Published: December 2017

AbstractDNA is often difficult to extract from old bones and teeth due to low levels of DNA and high levels of degradation. This study established a simple yet efficient method for extracting DNA from 20 aged bones and teeth (approximately 60 years old). Based on the concentration and STR typing results, the new method of DNA extraction (OM) developed in this study was compared with the PrepFiler™ BTA Forensic DNA Extraction Kit (BM). The total amount of DNA extracted using the OM method was not significantly different from that extracted using the commercial kit (p > 0.05). However, the number of STR loci detected was significantly higher in the samples processed using the OM method than using the BM method (p < 0.05). This study aimed to establish a DNA extraction method for aged bones and teeth to improve the detection rate of STR typing and reduce costs compared to the BM technique.

Abstract

The cost, usability and power efficiency of available wildlife monitoring equipment currently inhibits full ground‐level coverage of many natural systems. Developments over the last decade in technology, open science, and the sharing economy promise to bring global access to more versatile and more affordable monitoring tools, to improve coverage for conservation researchers and managers.

Here we describe the development and proof‐of‐concept of a low‐cost, small‐sized and low‐energy acoustic detector: “AudioMoth.” The device is open‐source and programmable, with diverse applications for recording animal calls or human activity at sample rates of up to 384 kHz. We briefly outline two ongoing real‐world case studies of large‐scale, long‐term monitoring for biodiversity and exploitation of natural resources. These studies demonstrate the potential for AudioMoth to enable a substantial shift away from passive continuous recording by individual devices, towards smart detection by networks of devices flooding large and inaccessible ecosystems.

The case studies demonstrate one of the smart capabilities of AudioMoth, to trigger event logging on the basis of classification algorithms that identify specific acoustic events. An algorithm to trigger recordings of the New Forest cicada (Cicadetta montana) demonstrates the potential for AudioMoth to vastly improve the spatial and temporal coverage of surveys for the presence of cryptic animals. An algorithm for logging gunshot events has potential to identify a shotgun blast in tropical rainforest at distances of up to 500 m, extending to 1 km with continuous recording.

AudioMoth is more energy efficient than currently available passive acoustic monitoring devices, giving it considerably greater portability and longevity in the field with smaller batteries. At a build cost of ∼US$43 per unit, AudioMoth has potential for varied applications in large‐scale, long‐term acoustic surveys. With continuing developments in smart, energy‐efficient algorithms and diminishing component costs, we are approaching the milestone of local communities being able to afford to remotely monitor their own natural resources.
Insolvent trading and voluntary administration in Australia: economic winners and losers?
Authors: Brotchie James , Morrison David 
Published: December 2017

AbstractAustralian directors who incur debts while their companies are insolvent can be pursued by the corporate regulator for compensation when their companies fail. Under the Australian insolvent trading laws, directors no longer experience ‘true’ limited liability, and as expected, they adjust their behaviour as a result. Identifying director's rational behaviour in an insolvent trading world is difficult as there are no formal economic models of director decision‐making under Australian current corporate law. In this paper, we develop such a model primarily for private companies. We incorporate the threat of insolvent trading as well as director's tactical use of voluntary administration to avoid insolvent trading litigation. We show that neither a combination of insolvent trading or voluntary administration can simultaneously ensure creditors‐best outcomes, eliminate insolvent trading and reduce director underinvestment.
HUMAN RESOURCE MANAGEMENT PRACTICES AND EMPLOYEE JOB SATISFACTION IN NONPROFIT ORGANIZATIONS
Authors: BASTIDA Ramon , MARIMON Frederic , CARRERAS Lluís 
Published: December 2017

ABSTRACTThe purpose of this study is to establish a measurement scale for human resource management (HRM) practices in nonprofit organizations and to analyze their impact on employee job satisfaction. An exploratory factor analysis (EFA) using a principal components was performed. The analyzed sample is composed of 62 organizations with 2,030 employees. The results demonstrate that 8 out of 20 analyzed variables determine the measurement scale of HRM practices in these organizations. These variables are related to psychological demands, active work and development possibilities, social relations and leadership, and the degree of coherence in the organization with its principles. According to the results, these practices have an impact on employee job satisfaction. We believe that these results are relevant due to the lack of similar studies and the relevance of nonprofit organizations as job creators in the European Union.
An Implicit SPH Formulation for Incompressible Linearly Elastic Solids
Authors: Peer Andreas , Gissler Christoph , Band Stefan , Teschner Matthias 
Published: December 2017

AbstractWe propose a novel smoothed particle hydrodynamics (SPH) formulation for deformable solids. Key aspects of our method are implicit elastic forces and an adapted SPH formulation for the deformation gradient that—in contrast to previous work—allows a rotation extraction directly from the SPH deformation gradient. The proposed implicit concept is entirely based on linear formulations. As a linear strain tensor is used, a rotation‐aware computation of the deformation gradient is required. In contrast to existing work, the respective rotation estimation is entirely realized within the SPH concept using a novel formulation with incorporated kernel gradient correction for first‐order consistency. The proposed implicit formulation and the adapted rotation estimation allow for significantly larger time steps and higher stiffness compared to explicit forms. Performance gain factors of up to one hundred are presented. Incompressibility of deformable solids is accounted for with an ISPH pressure solver. This further allows for a pressure‐based boundary handling and a unified processing of deformables interacting with SPH fluids and rigids. Self‐collisions are implicitly handled by the pressure solver.
Diagnostic accuracy of high‐resolution T2‐weighted MRI vs contrast‐enhanced T1‐weighted MRI to screen for cerebellopontine angle lesions in symptomatic patients

Published: December 2017

ObjectiveTo evaluate diagnostic accuracy of high‐resolution T2‐weighted MRI (T2w) for detecting cerebellopontine angle (CPA) lesions compared to a combined protocol including gadolinium enhanced T1‐weighted MRI (GdT1w).SettingDepartment of Radiology & Nuclear Medicine, Radboud University Medical Centre, Nijmegen, The Netherlands.ParticipantsA random sample of MRIs from 350 patients (700 CPAs) with asymmetrical audiovestibular complaints was used, acquired between 2013 and 2016.Main outcome measuresSensitivity, specificity, positive and negative predictive values of T2w results compared to GdT1w and, in patients with any suggestion of CPA pathology, to the complete examination (T1w, GdT1w and T2w). Inter‐rater agreement between an experienced neuroradiologist and a less experienced observer was calculated.ResultsResults of 678 CPAs in 340 patients were analysed. On T2w, the neuroradiologist identified all 27 lesions >2 mm in size out of a total of 30 CPA lesions (sensitivity: 90% [95% CI: 73.5%‐97.9%]). Negative predictive value reached 99.5% (95% CI: 98.7‐99.9). One missed lesion of 2 mm would have been detected in clinical practice, as this was one of 14 patients for which additional GdT1w would have been ordered based on T2w alone, increasing sensitivity to 93% (95% CI: 77.9%‐99.2%) and negative predictive value to 99.7% (95% CI: 98.9%‐100%). Inter‐rater agreement for T2w was 98% (95% CI: 96.4‐98.8).ConclusionT2w has a very high diagnostic accuracy for the presence of CPA lesions in patients with asymmetrical audiovestibular complaints. However, in a screening protocol with T2w only, smallest vestibular schwannomas as well as rare differential diagnoses that probably only would be detected on GdT1w may remain unnoticed.

AbstractBackgroundMedicines that exert oxidative pressure on red blood cells (RBC) can cause severe hemolysis in patients with glucose‐6‐phosphate dehydrogenase (G6PD) deficiency. Due to X‐chromosome inactivation, females heterozygous for G6PD with 1 allele encoding a G6PD‐deficient protein and the other a normal protein produce 2 RBC populations each expressing exclusively 1 allele. The G6PD mosaic is not captured with routine G6PD tests.MethodsAn open‐source software tool for G6PD cytofluorometric data interpretation is described. The tool interprets data in terms of % bright RBC, or cells with normal G6PD activity in specimens collected from 2 geographically and ethnically distinct populations, an African American cohort (USA) and a Karen and Burman ethnic cohort (Thailand) comprising 242 specimens including 89 heterozygous females.ResultsThe tool allowed comparison of data across 2 laboratories and both populations. Hemizygous normal or deficient males and homozygous normal or deficient females cluster at narrow % bright cells with mean values of 96%, or 6% (males) and 97%, or 2% (females), respectively. Heterozygous females show a distribution of 10‐85% bright cells and a mean of 50%. The distributions are associated with the severity of the G6PD mutation.ConclusionsConsistent cytofluorometric G6PD analysis facilitates interlaboratory comparison of cellular G6PD profiles and contributes to understanding primaquine‐associated hemolytic risk.
