Published: August 2017

Abstract
Quantum repeaters provide an efficient solution to distribute Bell pairs over arbitrarily long distances. While scalable architectures are demanding regarding the number of qubits that need to be controlled, here we present a quantum repeater scheme aiming to extend the range of present day quantum communications that could be implemented in the near future with trapped ions in cavities. We focus on an architecture where ion-photon entangled states are created locally and subsequently processed with linear optics to create elementary links of ion-ion entangled states. These links are then used to distribute entangled pairs over long distances using successive entanglement swapping operations performed using deterministic ion-ion gates. We show how this architecture can be implemented while encoding the qubits in a decoherence-free subspace to protect them against collective dephasing. This results in a protocol that can be used to violate a Bell inequality over distances of about 800 km assuming state-of-the-art parameters. We discuss how this could be improved to several thousand kilometres in future setups.
Using Economic Evaluation to Illustrate Value of Care for Improving Patient Safety and Quality: Choosing the Right Method
Authors: Padula William V. , Lee Ken K.H. , Pronovost Peter J. 
Published: August 2017

Abstract
To scale and sustain successful quality improvement (QI) interventions, it is recommended for health system leaders to calculate the economic and financial sustainability of the intervention. Many methods of economic evaluation exist, and the type of method depends on the audience: providers, researchers, and hospital executives. This is a primer to introduce cost-effectiveness analysis, budget impact analysis, and return on investment calculation as 3 distinct methods for each stakeholder needing a measurement of the value of QI at the health system level. Using cases for the QI of hospital-acquired condition rates (e.g., pressure injuries), this primer proceeds stepwise through each method beginning from the same starting point of constructing a model so that the repetition of steps is minimized and thereby capturing the attention of all intended audiences.
Effect of 40Gy irradiation on the ultrastructure, biochemistry, morphology and cytology during spermatogenesis in the southern green stink bugNezara viridula(Hemiptera: Pentatomidae)

Published: August 2017

AbstractA study on theNezara viridulamale gonad cells was undertaken to compare normal development and development of insect cells after irradiation of 4thinstar nymphs with a dose of 40 Gray. Visually, morphologically, biochemically and cytologically the insects were not all uniformly affected by the radiation. In all aspects of development there was a range from severely affected to nearly normal. Irradiated insects appeared to move slowly and were unable to mate with non-irradiated females. The testes of the males varied from bright orange to grey in colour and all were smaller in size than non-irradiated testes. The ultrastructure of the developing sperm showed abnormalities the axonemes, the mitochrondrial derivatives, nebenkern and centrioles. Cytochemically, the main difference observed was the presence of granules heavily stained with acid phosphatase in between mitochrondrial derivatives. The chromosomes of these irradiated insects were highly fragmented. Although a few sperm in irradiated insects appeared normal no progeny were produced as insect did not mate. The sterile insect technique (SIT) requires a balance between the effective radiation dose to achieve partial or full sterility, while maintaining physical fitness. The observation that abnormalities varied from almost none to severe at 40Gy could help the development of SIT for control ofN.viridulaand other Pentatomidae.

Published: August 2017

AbstractAnti-infective potential of a polyherbal ayurvedic formulation namelypanchvalkalwas assayed against three pathogenic bacteria. This formulation was found to exert quorum-modulatory effect onChromobacterium violaceum,Serratia marcescens, andStaphylococcus aureusat 250-750 μg/mL. Besides altering production of the quorum sensing-regulated pigments in these bacteria, the test formulation also hadin vitroeffect on antibiotic susceptibility, catalase activity and hemolytic potential of the pathogens.In vivoassay confirmed the protective effect of thispanchvalkalformulation onCaenorhabditis elegans, when challenged with the pathogenic bacteria. Repeated exposure ofS. aureustopanchvalkaldid not induce resistance in this bacterium. To the best of our awareness, this the first report on quorum-modulatory potential ofpanchvalkalformulation, validating the anti-infective potential and moderate prebiotic property of this polyherbal preparation.
Questioning worth: selling out in the music industry
Authors: Bridson Kerrie , Evans Jody , Varman Rohit , Volkov Michael , McDonald Sean 
Published: August 2017

PurposeThis study aims to illuminate the way in which consumers question the authenticity and worth of musicians, leading to a classification of selling out. The authors contribute to the debate on authenticity by attending to the question of worth that is under-examined in existing literature, by drawing upon French pragmatic sociology with specific attention to convention theory to understand conflicting interpretations of worth.Design/methodology/approachThe considerations music fans go through navigating whether artists are selling out and the loss of worth were explored through 22 semi-structured interviews, complemented by focus group discussions (20 participants) and analysis of an online video blog.FindingsThe study identified three key themes: “Authenticity and Worth in the Inspired World”, “Selling Out as Loss of Worth” and “Signifiers of Selling Out”.Practical implicationThe emergent themes enable us to understand the worth that consumers place on musical artists, and the clash between the ideologies of the market world and the inspired world. The ideas regarding selling out and the signifiers may apply to other consumption experiences where the clash between the inspired and the market worlds exists and the conflicting ethos of each can lead to a loss of worth and selling out.Originality/valueIn this research, the authors examine situations in which consumers stigmatise as “sell outs”, artists who are marketised under the influence of capitalist social relations of production. As a result, these artists lose their authenticity and worth in the eyes of consumers. In doing so, this research contributes to the debate on authenticity by attending to the question of worth that is under-examined in existing literature.
Domain-specific market segmentation using a latent class mixture modelling approach and wine-related lifestyle (WRL) algorithm
Authors: Bruwer Johan , Li Elton 
Published: August 2017

Purpose
Since the publication of Van Raaij and Verhallen’s seminal work in European Journal of Marketing in 1994, identifying the domain-specific market segmentation approach as one of the most feasible for segmenting markets, there has been surprisingly limited development in this field, with the food domain as the only exception. This study aims to develop a methodological approach using latent class mixture modelling as contribution in the domain-specific market segmentation field.

Design/methodology/approach
This study captures the AIO lifestyle perspective using a domain-specific 80-item algorithm which has the wine (product) domain as its focus. A sample size of 811 consumers is used from data collected by means of the CATI approach.

Findings
The authors use four criteria for model selection: comparison of the Bayesian information criterion (BIC) statistic, comparison of classification error, verification of the interpretation of the derived segments and, finally, use of the conditional bootstrap procedure to test whether the selected model provides a significant improvement over the previous model. The five-segment model option yields a minimum BIC, the classification error measure is minimal and is easier to interpret than the other models. Segment descriptions for the five identified lifestyle-based segments are developed.

Research limitations/implications
Segmentation by traditional k-means clustering has proven to be less useful than the more innovative alternative of mixture regression modelling; therefore, the authors identify segments in the market on the basis of individuals’ domain-specific lifestyle characteristics using a latent class mixture modelling approach.

Practical implications
Following the attainment of a clear and robust market segmentation structure, the simultaneous analysis of the lifestyles, demographics and behaviours of consumers as nexus of the domain-specific segmentation approach, provides rich and valid information accurately informing the market segment descriptions.

Originality/value
The authors make a substantive contribution by developing a methodological approach using latent class mixture modelling; the first of its kind in the area of domain-specific segmentation. Next, they use the discriminant and/or predictive validity of the 80-scale items to predict cluster membership using the WRL algorithm. Finally, the authors describe the identified market segments in detail and outline the practical implications.
Library staff recruitment and retention for managerial positions in Vietnam
Authors: Huynh Trang Thi 
Published: August 2017

Purpose
This paper aims to conduct an exploratory research of recruitment source and professional staff retention for succession planning, as well as suggests some experiences of keeping qualified staff in Vietnamese libraries. It stems from the context of academic and public libraries in the Mekong Delta region, Vietnam.

Design/methodology/approach
This research draws on transformational leadership theory initiated by Burns (1978) and expanded by Bass (1985). It was conducted through a multi-method case study approach at 13 public and 4 academic libraries in the Mekong Delta, Vietnam. Data collection consisted of an online survey with 162 responses and 23 in-depth semi-structured interviews.

Findings
Research result indicates that staff recruitment for managerial positions in Vietnamese libraries is mainly from within the organisation. Staff retention relies on differing factors, of which salary was considered the most important by several participants. However, succession planning itself may be a good way to keep qualified employees who would like to be promoted. For those employees attracted by high salaries rather than future managerial positions, supplemental income is believed to be a possible solution.

Research limitations/implications
A larger research coverage will be suggested to further research, so as to get further information about staff recruitment and how to retain qualified staff in Vietnamese library settings.

Practical implications
This study aims to benefit library leaders by providing good insights into which recruitment source is suitable to look for qualified staff for managerial positions in Vietnam. Most importantly, the research would inform library leaders and the local government in the Mekong Delta of the possible reasons for staff turnover. This study also helps to raise library leaders’ awareness of how to retain their qualified professional employees within a highly dynamic environment.

Originality/value
This research contributes to literature about qualified staff recruitment and retention in an Asian country context, which has not been discussed so far. It also helps to raise awareness of library leaders about applying some practical strategies, including succession planning, into retaining managing employees in their organisations.

hybriddetective: A workflow and package to facilitate the detection of hybridization using genomic data in r
Authors: Wringe Brendan F. , Stanley Ryan R. E. , Jeffery Nicholas W. , Anderson Eric C. , Bradbury Ian R. 
Published: August 2017

AbstractThe ability to detect and characterize hybridization in nature has long been of interest to many fields of biology and often has direct implications for wildlife management and conservation. The capacity to identify the presence of hybridization, and quantify the numbers of individuals belonging to different hybrid classes, permits inference on the magnitude of, and timescale over which, hybridization has been or is occurring. Here, we present an r package and associated workflow developed for the detection, with estimates of efficiency and accuracy, of multigenerational hybrid individuals using genetic or genomic data in conjunction with the program newhybrids. This package includes functions for the identification and testing of diagnostic panels of markers, the simulation of multigenerational hybrids, and the quantification and visualization of the efficiency and accuracy with which hybrids can be detected. Overall, this package delivers a streamlined hybrid analysis platform, providing improvements in speed, ease of use and repeatability over current ad hoc approaches. The latest version of the package and associated documentation are available on GitHub (https://github.com/bwringe/hybriddetective).

Published: August 2017

AbstractIntroductionThe proportion of women who postpone childbearing is increasing. As malignancy risk increases with age, pregnancy in connection with malignancy will become more common.Material and methodsWe compared infants born 1994–2011 to women with a malignancy within six months prior to the last menstrual period or during pregnancy with offspring of women without a previous malignancy. Five national registers were used.ResultsA total of 790 women with a malignancy diagnosis from six months prior to the last menstrual period up to delivery were identified. Their 802 infants were compared with 1 742 757 infants of women without a malignancy. A high rate of prematurity was found, especially when the malignancy was diagnosed during the second or third trimesters (33%). Most of these premature births were the result of induced delivery before 35 weeks (91%). The most remarkable finding is the observation that these premature infants had a significantly higher risk for neonatal morbidity than premature infants in the control group with an adjusted odds ratio of 2.67 (95% confidence interval; 1.86–3.84). We found a significantly increased risk of mainly relatively mild malformations among infants of women with a malignancy diagnosis within six months prior to the last menstrual period or during the first trimester with a risk ratio of 1.81 (95% confidence interval; 1.20–2.61).ConclusionsA high incidence of prematurity, mostly due to induced delivery, was found, including an increased risk for neonatal morbidity among these infants. An increased risk for relatively mild malformations was also found.

Serous‐lined, stapled pouch wall plication: initial results of a simple and quick novel continence mechanism in troubleshooting secondary to continent cutaneous urinary diversion
Authors: Riedmiller Hubertus , Kocot Arkadius , Kalogirou Charis 
Published: August 2017

ObjectivesTo report a novel and straightforward technique of a secondary continent outlet for continent cutaneous urinary diversion (CCUD) reservoirs without the need for further bowel resection, reducing operating time and length of hospitalization.Patients and MethodsFrom 2015 to 2017, six patients with unreconstructable, incontinent outlets (out of a total pool of 595 patients with CCUD) have undergone the technique described in the present paper at our department. The technique relies on the Mitrofanoff principle, using a stapled full‐thickness pouch wall plication, which creates a flap‐valve continence mechanism.ResultsAll patients enjoyed full continence with ease of clean intermittent catheterization (CIC) in the postoperative period and on follow‐up to a mean (range) of 12.4 (7–18) months. No major complications were encountered in any patient and the average capacity of the reservoirs was not compromised by the procedure (540 mL preoperatively vs 500 mL in further follow‐up).ConclusionIn revisional surgery for secondary CCUD incontinence, especially if the patient has already lost a significant amount of bowel or has previously undergone radiation therapy, the technique described here represents a safe and effective alternative to restore continence.
Longitudinal vocabulary development in Australian urban Aboriginal children: Protective and risk factors
Authors: Short K. , Eadie P. , Descallar J. , Comino E. , Kemp L. 
Published: August 2017

AbstractBackgroundVocabulary is a key component of language that can impact on children's future literacy and communication. The gap between Australian Aboriginal and non‐Aboriginal children's reading and academic outcomes is well reported and similar to Indigenous/non‐Indigenous gaps in other nations. Determining factors that influence vocabulary acquisition over time and may be responsive to treatment is important for improving Aboriginal children's communication and academic outcomes.AimTo determine what factors influence Australian urban Aboriginal children's receptive vocabulary acquisition and whether any of these are risks or protective for vocabulary development.MethodOne hundred thirteen Aboriginal children in South Western Sydney from the longitudinal birth cohort Gudaga study were assessed on The Peabody Picture Vocabulary Test multiple times: 3 years, just prior to school entry, at the end of the first and second years of formal schooling. Multilevel models were used to determine the effects of 13 fixed and manipulable maternal, child, and family variables drawn from previous research.ResultsHigher maternal education was found to be protective at 3 years and over time. The number of children in urban Australian Aboriginal households made an impact on vocabulary development and this varied over time. From 3 to 6 years, those with early poor non‐verbal cognitive skills had vocabulary skills that remained below those with stronger non‐verbal skills at 3 years. Girls exhibit an earlier advantage in vocabulary acquisition, but this difference is not sustained after 4 years of age.ConclusionsThe risk and protective factors for vocabulary development in Australian Aboriginal children are similar to those identified in other studies with some variation related to the number of children in the home. In this limited set of predictors, maternal education, gender, non‐verbal cognitive skills, and the number of children in households were all shown to impact on the acquisition of vocabulary to 3 years and or the developmental trajectory over time.

Published: August 2017

AbstractBackgroundExtremely low birth weight (ELBW; <1,000 g) infants are the most vulnerable babies and are at higher risk for experiencing overprotective (i.e., controlling and intrusive) parenting, which is hypothesized to contribute to the risk for mental disorders. Despite the increased risk for anxiety disorders and decreased risk for alcohol or substance use disorders seen in ELBW survivors, no research has examined the impact of parenting. This study investigated if overprotective parenting mediates links between ELBW birth status and psychiatric disorders in adulthood.Study designParticipants included ELBW survivors born in 1977–1982 and matched normal birth weight (≥2,500 g) control participants (ELBW n = 81; normal birth weight n = 87) prospectively followed in Ontario, Canada. These individuals retrospectively reported on whether either of their parents was overprotective using the Parental Bonding Instrument. Presence of a current anxiety disorder and of current alcohol or substance use disorders was assessed using the Mini International Neuropsychiatric Interview at age 29–36 years.ResultsPath analysis showed that overprotective parenting was a significant mediator of the association between ELBW status and risk for an anxiety disorder in adulthood and the risk for an alcohol or substance use disorder in adulthood in ELBW survivors. Overprotective parenting accounted for 53% of the association between ELBW status and the risk for an anxiety disorder in adulthood and 26% of the association between ELBW status and alcohol or substance use disorders.ConclusionsOverprotective parenting accounted for a substantial proportion of the increased risk for anxiety and alcohol or substance use disorders in adulthood in ELBW survivors. Despite their perceived vulnerabilities, it is important that the parents of ELBW survivors be supported in their attempts to facilitate their children's pursuit of independence during childhood and beyond.
