Authors: Wang Jiayi , Tao Dongbing , Liu Yubo , Han Siwen , Zheng Fenge , Wu Zhaoxia 
Published: June 2018

ABSTRACTIn this study, we aimed to determine the organic acids (acetic, lactic, citric, malic, propionic, succinic, and tartaric acids; 1% and 0.5%, w/w or v/v) that were most effective for fresh-cut lettuce disinfection based on analysis of quality (i.e., color, electrolyte leakage, and sensory quality) and microbial examination. The results showed that these acids did not negatively affect the color quality (i.e., L*, a*, b*, whiteness index, and sensory color). Additionally, 0.5% lactic acid led to the lowest electrolyte leakage (0.83%), which was not significantly different (p > 0.05) from that of distilled water (0.46%). Lactic acid (1%) did not affect the sensory quality and led to the highest microbial reduction (1.45 log reduction in aerobic plate counts [APCs]; 2.31 log reduction in molds and yeasts [M&Y]) and was therefore recommended as the primary choice for lettuce disinfection. Malic acid (0.5%), with a 1.07% electrolyte leakage rate, 0.73 log reduction in APCs, and 1.40 log reduction in M&Y, was better than the other six acids (0.5%) and was recommended as a pH regulator and a potential synergistic agent for oxidizing sanitizers. Acetic acid (1%) negatively affected the sensory quality and led to the highest electrolyte leakage (2.90%). Microbial analysis showed that propionic acid (0.5% and 1%) was ineffective for disinfection of lettuce (p > 0.05); thus, acetic and propionic acids were not recommended. Our results provide insights into the choice of sanitizers and formula design in food safety.IMPORTANCESince chlorine is forbidden in several countries, generally recognized as safe organic acids are used in minimal processing industries and in household sanitizers. The disinfection efficacy of organic acids has been studied when used alone or with oxidizing sanitizers. However, since different antibacterial mechanisms, contact time, fresh produce, and concentration have been reported, the acids most effective for single fresh produce disinfection, especially that of lettuce, an important salad vegetable, are not known. Moreover, in developing countries, because of imperfections in field management, cold chain transportation, and minimal processing industry development, the demand for low-cost household sanitizers is greater than that for minimally processed fresh produce. In this work, microbial load in lettuce was determined after disinfecting with seven GRAS organic acids. The changes in quality were also determined. These results provide insights into the choice of minimal processing sanitizers and a formula design for household sanitizers.
Does marital status affect how firms interpret job applicants’ un/employment histories?
Authors: Maurer-Fazio Margaret , Wang Sili 
Published: June 2018

PurposeThe purpose of this paper is to explore whether single and married female job candidates’ un/employment histories differentially affect their chances of obtaining interviews through China’s internet job boards, and to consider whether firms’ discrimination against, and/or preference for, candidates who are un/employed vary with the duration of unemployment spells.Design/methodology/approachResumes of fictitious applicants are carefully crafted in terms of realistic work histories and educational backgrounds. Candidates’ experiences of unemployment and the revelation of their marital status are controlled. Over 7,000 applications are submitted to real job postings. Callbacks are carefully tracked and recorded. Linear probability models are employed to assess the roles of particular characteristics.FindingsThe marital status of female candidates affects how recruiters screen their applications. While current spells of unemployment, whether short or long term, significantly reduce married women’s chances of obtaining job interviews in the Chinese context, they strongly increase the likelihood that single women will be invited for interviews. Chinese firms appear to “forgive” long-term gaps in women’s employment histories as long as those gaps are followed by subsequent employment.Originality/valueThis paper is the first to explore how marital status affects the ways that firms, when hiring, interpret spells of unemployment in candidates’ work histories. It is also the first to explore the effects of both marital status and unemployment spells in hiring in the context of China’s dynamic internet job board labor market.
The role of egocentric networks in achieving resilience: a case study from the apparel sector
Authors: Bhattacharjya Jyotirmoyee 
Published: June 2018

PurposeThe purpose of this paper is to explore the egocentric network-based strategies used by upstream firms to ensure their own resilience when the disruptions originate with downstream partners.Design/methodology/approachThe paper adopts a case study approach as this is well-suited to the investigation of a complex phenomenon from multiple perspectives.FindingsThe study finds that the egocentric networks of upstream firms participating in the supply network of a retailer could ensure their own resilience even after the sudden demise of the downstream entity.Originality/valueThe study addresses the lack of adequate empirical research examining resilience from the perspectives of multiple entities in a supply network. It is also one of the few papers to address resilience from the perspective of upstream players in the context of a disruption originating with downstream partners. The findings suggest that the lack of visibility in relation to the financial health of more powerful downstream partners could be problematic from a supplier’s perspective. It identifies well-developed egocentric networks as being essential for minimizing consequences of limited downstream visibility and the impact on social capital.
Kaizen: working responsively with psychopathic traits
Authors: Henfrey Sarah Anne 
Published: June 2018

Purpose
The purpose of this paper is to describe how Kaizen, an accredited offending behaviour programme designed for high risk and need offenders within Her Majesty’s Prison and Probation Service (HMPPS), lends itself to responsive delivery with those meeting the criteria for psychopathy.

Design/methodology/approach
The paper describes how the theoretical rationale and model of change underpinning Kaizen can be applied to those with high levels of psychopathic traits given the available literature in this area.

Findings
It is argued that Kaizen is applicable to those meeting the criteria for psychopathy.

Research limitations/implications
As a contemporary intervention, the efficacy of Kaizen in its ability to support participants in their journey towards desistance and therefore to contribute to the service wide aim of reducing reoffending is yet to be evaluated. In turn, its applicability to those meeting the criteria for psychopathy is yet to be explored.

Practical implications
This paper lends support to the applicability of Mann and Carter’s (2012) six organising principles of programme design in the treatment of high risk, high need offenders who meet the criteria for psychopathy. It encourages practitioners to consider Kaizen as a possible intervention option for this population and offers guidance as to how the programme might be used to best effect. The paper also highlights the importance of evaluating the efficacy of participation in Kaizen for this population.

Originality/value
In time, Kaizen will replace Chromis as the offer by Intervention Services (HMPPS) for high risk offenders with a high level or combination of psychopathic trait. This paper describes this forthcoming change in approach and the rationale underpinning it.

Published: June 2018

Purpose
The purpose of this paper is to review the Mental Health Foundation’s experiences designing, implementing and evaluating peer-focused self-management programmes. Through a discussion of barriers and good practice, it outlines ways to be successful in making such projects work to improve mental health and wellbeing among at-risk populations.

Design/methodology/approach
A total of 11 Mental Health Foundation programmes implemented over the past ten years were reviewed through reading manuals and publications and interviewing programme managers. Key data were extracted from each programme to analyse trends in aims, outcomes and recommendations.

Findings
Through a focus on peer-work, programmes taught individuals from a variety of societal sectors self-management skills to effectively deal with life stressors. Through sharing in non-judgmental spaces and taking ownership of programme design and content, individuals realised improvements in wellbeing and goal achievement.

Practical implications
Good practice, barriers and recommendations can be taken from this review and applied to future peer-focused self-management programmes. By better embedding quantitative and qualitative evaluations into programme development and implementation, programmes can add to the evidence base and effectively target needs.

Originality/value
This review lays out valuable experience on an innovative community service paradigm and supports the evidence on effectiveness of peer-focused self-management programmes with a variety of group populations.
Analysis of radial vibrations in thick walled hollow poroelastic cylinder in the framework of Biot’s extension theory
Authors: Gurijala Rajitha , Perati Malla Reddy 
Published: June 2018

Purpose
In this paper, wave propagation in a poroelastic thick-walled hollow cylinder is investigated in the framework of Biot’s extension theory. Biot’s theory of poroelasticity is valid for isotropic porous solids saturated with non-viscous fluid. The bulk and shear viscosities are not considered in the classical Biot’s theory. Biot’s extension theory takes all these into an account. Biot’s extension theory is applied here to investigate the radial vibrations in thick-walled hollow poroelastic cylinder. The paper aims to discuss these issues.

Design/methodology/approach
By considering the stress-free boundaries, the frequency equation is obtained in the presence of dissipation. Limiting case when the ratio between thickness and inner radius is very small is investigated numerically. In the limiting case, the asymptotic expansions of Bessel functions are employed so that frequency equation is separated into two parts which gives attenuation coefficient and phase velocity. If the shear viscosity is neglected, then the problem reduces to that of the classical Biot’s theory.

Findings
For the numerical purpose, the solids Berea sandstone and bone are used. The results are presented graphically.

Originality/value
Radial vibrations of thick-walled hollow poroelastic cylinder are investigated in the framework of Biot’s extension theory. Due to the mathematical complexity, limiting case is considered. The complex valued frequency equation is discussed numerically which gives the attenuation coefficient and phase velocity. If shear viscosity is neglected, then the problem reduces to that of the classical Biot’s theory. The comparison has been made between the current results and that of classical results.

Background and purposeAntibodies to glycine receptors (GlyR‐Abs) were first defined in progressive encephalopathy with rigidity and myoclonus (PERM) but were subsequently identified in other clinical presentations. Our aim was to assess the clinical associations of all patients identified with GlyR‐Abs in Queensland, Australia, between April 2014 and May 2017 and to compare these to cases reported in the literature.MethodsA literature review identified the clinical features of all published GlyR‐Ab‐positive cases through online databases. A case series was undertaken via collection of clinical information from all patients diagnosed or known to immunology, pathology or neurological services in Queensland during the study period of 3 years.ResultsIn all, 187 GlyR‐Ab‐positive cases were identified in the literature. The majority (47.6%) had PERM, 22.4% had epilepsy, but the remaining 30% included mixed phenotypes consisting of cerebellar ataxia, movement disorders, demyelination and encephalitis/cognitive dysfunction. By contrast, in our series of 14 cases, eight had clinical presentations consistent with seizures and epilepsy and only three cases had classical features of PERM. There was one case each of global fatiguable weakness with sustained clonus, laryngeal dystonia and movement disorder with hemiballismus and tics. The rate of response to immune therapy was similar in all groups.ConclusionAntibodies to glycine receptors are linked to a spectrum of neurological disease. The results of the literature review and our case series suggest a greater relationship between GlyR‐Abs and epilepsy than previously reported.
Ictal and preictal power changes outside of the seizure focus correlate with seizure generalization

Published: June 2018

SummaryObjectiveThe treatment of focal epilepsies is largely predicated on the concept that there is a “focus” from which the seizure emanates. Yet, the physiological context that determines if and how ictal activity starts and propagates remains poorly understood. To delineate these phenomena more completely, we studied activity outside the seizure‐onset zone prior to and during seizure initiation.MethodsStereotactic depth electrodes were implanted in 17 patients with longstanding pharmacoresistant epilepsy for lateralization and localization of the seizure‐onset zone. Only seizures with focal onset in mesial temporal structures were used for analysis. Spectral analyses were used to quantify changes in delta, theta, alpha, beta, gamma, and high gamma frequency power, in regions inside and outside the area of seizure onset during both preictal and seizure initiation periods.ResultsIn the 78 seizures examined, an average of 9.26% of the electrode contacts outside of the seizure focus demonstrated changes in power at seizure onset. Of interest, seizures that were secondarily generalized, on average, showed power changes in a greater number of extrafocus electrode contacts at seizure onset (16.7%) compared to seizures that remained focal (3.8%). The majority of these extrafocus changes occupied the delta and theta bands in electrodes placed in the ipsilateral, lateral temporal lobe. Preictally, we observed extrafocal high‐frequency power decrements, which also correlated with seizure spread.SignificanceThis widespread activity at and prior to the seizure‐onset time further extends the notion of the ictogenic focus and its relationship to seizure spread. Further understanding of these extrafocus, periictal changes might help identify the neuronal dynamics underlying the initiation of seizures and how therapies can be devised to control seizure activity.
Does the Mandatory Bid Rule Add Value to Target Shareholders?
Authors: Eswar Sapnoti K. 
Published: June 2018

AbstractI investigate whether implementation of the mandatory bid rule—the rule that grants all shareholders the right to participate in a takeover transaction at equal terms—affects target announcement returns. I use a difference‐in‐differences approach and the staggered adoption of the rule across 15 European countries. I find that the rule change leads to higher target returns. In full transactions, better accounting standards and shareholder protection norms of the acquirer leads to higher target returns. In majority transactions, greater value transfer from acquirers with weak accounting standards leads to higher target returns. I find weak evidence of overpayment by acquirers.

BackgroundCitation analysis reflects the scientific recognition and influential performance of an article in the scientific community. The objective of this study was to identify and characterize the 100 most cited articles on oral submucous fibrosis (OSF).MethodsA list of 100 most cited articles related to OSF was retrieved from the Science Citation Index‐Expanded tool of Scopus database in May 2018. The articles were further reviewed, and basic information was recorded including the number of citations, citation density, journals, with its impact factor, category and quartile, publication year, authors, institution and country of origin, article type and level of evidence. Descriptive statistics were used to summarize the results.ResultsThe most frequently cited article received 780 citations, while the least frequently cited article received 49 (mean 107.5 citations per article). There were 38 different journals with Journal of Oral Pathology and Medicine having the most citations (n = 22). The 100 most cited articles were published from 1966 to 2013, with 81% published after 1990. Thirteen authors listed 5 or more articles in the top 100 list, and India was found to be the most prolific country with 38 articles. In terms of article type, there were 72 research articles and 28 review articles.ConclusionsThis first citation analysis of the 100 most cited articles renders a historical perspective on the progress of research in the field of OSF and enables the comprehensive identification and recognition of the most important and relevant research topics concerned.
Presidential Address: Going Public: The Art and Science of Researching Domestic Violence and Religion
Authors: Nason‐Clark Nancy 
Published: June 2018

AbstractGoing public with our research is both an “art” and a “science.” It involves elements of “vulnerability” and elements of “resiliency,” two key themes that have emerged in my program of research on domestic violence and religion. I harness the concepts of vulnerability and resiliency to argue that public engagement involves the scholar in an ongoing negotiation between the science and the art of disseminating his or her research results. The article concludes with references to our web‐based resources (http://www.theraveproject.org) and the way we have used stained glass to tell the story of research results.
Replication‐coupled histone H3.1 deposition determines nucleosome composition and heterochromatin dynamics during Arabidopsis seedling development

Published: June 2018

Summary

Developmental phase transitions are often characterized by changes in the chromatin landscape and heterochromatin reorganization. In Arabidopsis, clustering of repetitive heterochromatic loci into so‐called chromocenters is an important determinant of chromosome organization in nuclear space. Here, we investigated the molecular mechanisms involved in chromocenter formation during the switch from a heterotrophic to a photosynthetically competent state during early seedling development.

We characterized the spatial organization and chromatin features at centromeric and pericentromeric repeats and identified mutant contexts with impaired chromocenter formation.

We find that clustering of repetitive DNA loci into chromocenters takes place in a precise temporal window and results in reinforced transcriptional repression. Although repetitive sequences are enriched in H3K9me2 and linker histone H1 before repeat clustering, chromocenter formation involves increasing enrichment in H3.1 as well as H2A.W histone variants, hallmarks of heterochromatin. These processes are severely affected in mutants impaired in replication‐coupled histone assembly mediated by CHROMATIN ASSEMBLY FACTOR 1 (CAF‐1). We further reveal that histone deposition by CAF‐1 is required for efficient H3K9me2 enrichment at repetitive sequences during chromocenter formation.

Taken together, we show that chromocenter assembly during post‐germination development requires dynamic changes in nucleosome composition and histone post‐translational modifications orchestrated by the replication‐coupled H3.1 deposition machinery.
Feeling the force: how pollen tubes deal with obstacles
Authors: Burri Jan T. , Vogler Hannes , Läubli Nino F. , Hu Chengzhi , Grossniklaus Ueli , Nelson Bradley J. 
Published: June 2018

Summary

Physical forces are involved in the regulation of plant development and morphogenesis by translating mechanical stress into the modification of physiological processes, which, in turn, can affect cellular growth. Pollen tubes respond rapidly to external stimuli and provide an ideal system to study the effect of mechanical cues at the single‐cell level. Here, pollen tubes were exposed to mechanical stress while monitoring the reconfiguration of their growth and recording the generated forces in real‐time.

We combined a lab‐on‐a‐chip device with a microelectromechanical systems (MEMS)‐based capacitive force sensor to mimic and quantify the forces that are involved in pollen tube navigation upon confronting mechanical obstacles. Several stages of obstacle avoidance were identified, including force perception, growth adjustment and penetration.

We have experimentally determined the perceptive force threshold, which is the force threshold at which the pollen tube reacts to an obstacle, for Lilium longiflorum and Arabidopsis thaliana. In addition, the method we developed provides a way to calculate turgor pressure based on force and optical data.

Pollen tubes sense physical barriers and actively adjust their growth behavior to overcome them. Furthermore, our system offers an ideal platform to investigate intracellular activity during force perception and growth adaption in tip growing cells.

It is widely accepted that the magnitude of the relationship between tree diversity and forest stand productivity is context specific and depends on environmental conditions, but the underlying mechanisms of this relationship are still not fully understood. Competition reduction and facilitation have been identified as key mechanisms driving the diversity–productivity relationship. However, contrasting results have been reported with respect to the extent to which competition reduction and facilitation determine the diversity–productivity relationship. They appear to depend on regional climate, soil fertility, functional diversity of the tree species involved, and developmental stage of the forest. The purpose of this review is to summarize current knowledge and to suggest a conceptual framework to explain the various processes leading to higher productivity of species‐rich forests compared with average yields of their respective monocultures. This framework provides three pathways for possible development of the diversity–productivity relationship under a changing climate.
