Construction and Elaboration of Autobiographical Memories from Multiple Visual Perspectives
Authors: Iriye Heather , St. Jacques Peggy L. 
Published: May 2018

AbstractVisual perspective, recalling events from one’s own eyes or from an observer-like viewpoint, is a fundamental aspect of autobiographical memory (AM). Yet, how visual perspective influences the functional mechanisms supporting retrieval is unclear. Here, we used a multivariate neuroimaging analysis to characterize the spatiotemporal dynamics supporting AM retrieval from multiple visual perspectives. Both own eyes and observer perspectives engaged an AM retrieval network (i.e., hippocampus, anterior and posterior midline, lateral frontal and posterior cortices) that peaked during later retrieval periods but was recruited less strongly for observer perspectives. Functional connectivity analyses with an anterior hippocampal seed revealed that visual perspective also altered interactions among neural regions and their timing during retrieval. There was stronger hippocampal connectivity with a posterior medial network during the initial construction of AMs from observer perspectives and stronger connectivity with a medial temporal lobe network during later retrieval periods from own eyes perspectives, suggesting that visual perspective directs how neocortical systems guide retrieval. Our findings demonstrate that visual perspective influences AM retrieval by altering hippocampal-neocortical interactions and subsequently the strength of neural recruitment in the AM retrieval network during later retrieval periods, thereby supporting the central role of visual perspective in shaping the personal past.
A Neural Ensemble Correlation Code for Sound Category Identification

Published: May 2018

ABSTRACTHumans and other animals effortlessly identify sounds and categorize them into behaviorally relevant categories. Yet, the acoustic features and neural transformations that enable the formation of perceptual categories are largely unknown. Here we demonstrate that correlation statistics between frequency-organized cochlear sound channels are reflected in the neural ensemble activity of the auditory midbrain and that such activity, in turn, can contribute to discrimination of perceptual categories. Using multi-channel neural recordings in the auditory midbrain of unanesthetized rabbits, we first demonstrate that neuron ensemble correlations are highly structured in both time and frequency and can be decoded to distinguish sounds. Next, we develop a probabilistic framework for measuring the nonstationary spectro-temporal correlation statistics between frequency organized channels in an auditory model. In a 13-category sound identification task, classification accuracy is consistently high (>80%), improving with sound duration and plateauing at ~ 1-3 seconds, mirroring human performance trends. Nonstationary short-term correlation statistics are more informative about the sound category than the time-average correlation statistics (84% vs. 73% accuracy). When tested independently, the spectral and temporal correlations between the model outputs achieved a similar level of performance and appear to contribute equally. These results outline a plausible neural code in which correlation statistics between neuron ensembles of different frequencies can be read-out to identify and distinguish acoustic categories.
The spectral identity of foveal cones is preserved in hue perception

Published: May 2018

AbstractOrganisms are faced with the challenge of making inferences about the physical world from incomplete incoming sensory information. One strategy to combat ambiguity in this process is to combine new information with prior experiences. We investigated the strategy of combining these information sources in color vision. Single cones in human subjects were stimulated and the associated percepts were recorded. Subjects rated each flash for brightness, hue and saturation. Brightness ratings were proportional to stimulus intensity. Saturation was independent of intensity, but varied between cones. Hue, in contrast, was assigned in a stereotyped manner that was predicted by cone type. These experiments revealed that, near the fovea, long (L) and middle (M) wavelength sensitive cones produce sensations that can be reliably distinguished on the basis of hue, but not saturation or brightness. Taken together, these observations implicate the high-resolution, color-opponent parvocellular pathway in this low-level visual task.
A novel role of VisP and the Wzz system during O-antigen assembly inSalmonellaTyphimurium pathogenesis

Published: May 2018

AbstractSalmonella entericaserovars are associated with diarrhea and gastroenteritis and are a helpful model for understanding host-pathogen mechanisms.SalmonellaTyphimurium regulates the distribution of O-antigen (OAg) and presents a trimodal distribution based on Wzy polymerase, WzzST(long chain length OAg, L-OAg) and WzzfepE(very long chain length OAg, VL-OAg) co-polymerases; however, several mechanisms regulating this process remain unclear. Here, we report that LPS modifications modulate the infectious process and that OAg chain length determination plays an essential role during infection. An increase in VL-OAg is dependent on Wzy polymerase, which is promoted by a growth condition resembling the environment ofSalmonella-containing vacuoles (SCVs). The virulence and stress-related periplasmic protein (VisP) participates in OAg synthesis, as ΔvisPpresents a semirough OAg phenotype. The ΔvisPmutant has greatly decreased motility and J774 macrophage survival in a colitis model of infection. Interestingly, the phenotype is restored after mutation of thewzzSTorwzzfepEgene in a ΔvisPbackground. Loss of both thevisPandwzzSTgenes promotes an imbalance in flagellin secretion. L-OAg may function as a shield against host immune systems in the beginning of an infectious process, and VL-OAg protects bacteria during SCV maturation and facilitates intramacrophage replication. Taken together, these data highlight the roles of OAg length in generating phenotypes duringS.Typhimurium pathogenesis and show the periplasmic protein VisP as a novel protein in the OAg biosynthesis pathway.Author summarySalmonellamodifies its LPS, specifically the O-antigen length, to adapt itself to distinct intestinal environments. These LPS modifications may provide a way for this bacterium to avoid complement activation in the intestinal lumen, improvingSalmonellapathogenesis. This process is essential for a successful infection, and our investigation into these specific details regarding LPS in this foodborne pathogen will elucidate different aspects of the host-pathogen association.
The impact of firm resources on innovation
Authors: Demirkan Irem 
Published: May 2018

PurposeThe purpose of this paper is to propose that the resources that a firm owns and has full control (firm-level resources) and resources that a firm access through direct connection with other firms (network-level resources) will impact firm innovation when effectively deployed by the firm. While previous research examined these factors separately, the author takes a holistic view and looks into their effects on innovation simultaneously. The author also introduces the moderating effects, i.e. the variables that can enhance firm innovation through their interaction with internal and external resources.Design/methodology/approachThe author tested the role of financial resources and slack resources in the form of cash slack and human slack at the firm level, and network size, network tie strength, and network diversity at the network level on the firm innovation. Using generalized negative binomial model with Huber-White procedure, the author analyzed 306 firms from the biotechnology industry over a span of 17 years.FindingsThe analysis suggests that cash slack impact innovation negatively. However, this link is moderated by firm size such that for large firms cash slack affects innovation positively. Network-level resources all positively impact innovation and have more economic impact on firm innovation than firm-level resources. Furthermore, although human slack negatively affects innovation, its interaction with network size enhances innovation.Originality/valueThe research makes important contributions to both strategic management and innovation literatures especially when, the author considers the role of firm-level slack in driving firm innovation. Previous research reported conflicting findings about the availability of slack resources and firm performance. The results showed that the relationship between slack resources and firm innovation is negative and significant, both for available slack and human slack. This finding parallels with previous research which reported that constraints such as lack of slack resources can actually facilitate innovation. The author also contributes to the literature by introducing boundary conditions which can enhance firm innovation through their interaction with firm-level internal and network-level external resources. In this respect, to the author’s knowledge, this is among the first studies to combine the slack literature focusing on firm-level resources with the literature on network-level resources.
Service quality evaluation and the mediating role of perceived value and customer satisfaction in customer loyalty
Authors: Keshavarz Yousef , Jamshidi Dariyoush 
Published: May 2018

Purpose
Loyalty has become the most important strategic aim in the hotel industry. The purpose of this paper is to obtain an empirical understanding of loyalty in the Kuala Lumpur hotel sector.

Design/methodology/approach
The dimensions of service quality as perceived by hotel customers were identified through the literature review. Hypotheses were formulated and tested to: examine the effects of process quality and outcome quality on perceived value, tourist satisfaction, and tourist loyalty; and to determine if perceived value and tourist satisfaction play a mediating role in the effect of process quality and outcome quality on tourist loyalty. In this study, the sample was 417 respondents from the international tourists who stay at least one night in four- or five stars hotels in Kuala Lumpur. Collected data were analyzed by structural equation modeling.

Findings
The statistical findings supported a relationship between process quality and outcome quality with perceived value and tourist satisfaction, and tourist loyalty with perceived value and tourist satisfaction. The results also indicated that process quality and outcome quality did not have a direct effect on tourist loyalty. Perceived value and tourist satisfaction mediated the relationship between process quality and outcome quality with tourist loyalty.

Originality/value
The finding of this study proposed that the hoteliers targeting international tourists with service quality including process and outcome quality should focus more on these factors to build loyalty. For instance, the tangible, responsiveness, reliability, empathy, assurance, and convenience as the dimensions of process quality and valence, waiting time, and sociability as the dimensions of outcome quality should meet the needs of the international tourists, therefore increasing tourist loyalty through perceived value and tourist satisfaction.

Published: May 2018

Purpose
The purpose of this paper is to investigate the influence of gender on attitude towards the use of social media for continuing professional development among academic librarians in Ogun State, Nigeria.

Design/methodology/approach
Descriptive survey design was used for the study. Research instrument used was questionnaire where 79 copies were administered to academic librarians, using total enumeration sampling technique. Five universities in Ogun State, Nigeria were selected for the study. The data collected were analysed using descriptive and inferential statistics such as percentage, frequency, mean, Pearson product moment correlation coefficient and t-test for data analysis. Statistical Package for Social Sciences (SPSS, version 19) was used to run the analysis.

Findings
The study revealed that WhatsApp (75.0 per cent) is the most frequently used social media for continuing professional development among academic librarians. Attitude towards the use of social media for continuing professional development among academic librarians is positive. There is no statistically significant gender difference in attitude towards the use of social media for continuing professional development (t = 0.097, df = 54 and p > 0.05). There is significant moderate positive relationship between attitude towards social media use and frequency of use of social media (r = 0.439; p < 0.05).

Originality/value
The study was necessary to identify gender difference in attitude towards the use of social media for continuing professional development by academic librarians in Ogun State, Nigeria.
How and when do employees identify with their organization? Perceived CSR, first-party (in)justice, and organizational (mis)trust at workplace
Authors: Ghosh Koustab 
Published: May 2018

PurposeThe purpose of this paper is to inquire how and when the CSR efforts of an organization can generate positive organizational outcomes by influencing individual employees at the workplace. Theorizing perceived first-party justice as psycho-cognitive and affect-based organizational trust as psycho-affective processes, respectively, in interpreting employees’ perception of organizational CSR initiatives provided a valid rationale behind this research.Design/methodology/approachFollowing a two-phase longitudinal research design, sample was drawn from six subsidiary organizations of a multinational conglomerate.FindingsThe findings indicated that the perceived internal image of CSR predicts employees’ deep organizational identification through the mediation of affect-based organizational trust, conditional on perceived first-party justice as a moderator.Research limitations/implicationsThis study contributed to extant research by investigating the hitherto unexplored question of how and when employees’ perceived image of CSR delineates to their deep identification with the organization supported by affect-based organizational trust and self-experienced first-party justice. The collection of survey responses within six group organizations could limit the generalization of the findings from this study in other contexts.Practical implicationsThis study offers significant implications in terms of the managers’ role in involving employees in the organization’s CSR activities, using CSR as a platform for corporate branding to internal stakeholders, and attracting talent in knowledge intensive competition.Originality/valueThe study advances the emerging micro-level approach of CSR by exploring an employee centric, personalized view of organizational CSR and estimating its effect at the level of individual employees.

Published: May 2018

AbstractA working group of dermatologists in Asian countries assessed the current status of psoriatic management in the region to prepare a consensus report on topical treatment in mild to moderate plaque psoriasis. Even though the association of psoriasis with systemic comorbidities is increasingly acknowledged, psoriasis is still lower in health‐care priority lists in the region. The psychosocial impact of psoriasis may be greater in Asian countries due to cultural norms and social discrimination. Non‐adherence to treatment is also common among Asians. The current care given to patients with mild to moderate psoriasis needs to be streamlined, enhanced and organized with a patient‐centered care approach to achieve better outcomes. A comprehensive assessment of the disease severity and its impact on a patient's life is required before initiating treatment. Education and active involvement of the patient in the treatment plan is an important part of psoriatic management. It is recommended to personalize topical treatment to meet the needs of the patient, depending on disease severity, psychosocial impact, the patient's expectations and, more importantly, the patient's willingness and ability to actively follow the treatment procedure. Fixed‐dose combination of corticosteroid and vitamin D analogs is the preferred topical medication for both initial and maintenance phases of treatment. The fast containment of the disease is the goal of the initial phase of 4–8 weeks and it demands a potent fast‐acting topical therapy. Satisfactory control of the disease and prevention of relapses should be achieved during the maintenance phase with twice a week or weekend applications.

BackgroundPlacental anomalies (placenta praevia, placental abruption, morbidly adherent placenta and cord insertion anomalies) are associated with maternal and fetal morbidity and mortality. It has been suggested these might be more prevalent in pregnancies after assisted reproduction technology (ART).ObjectivesTo determine whether ART singleton pregnancies are associated with an increased risk of placental anomalies compared with non‐ART singleton pregnancies.Search strategyMEDLINE, EMBASE, CENTRAL, Web of Science and Scopus (January 2018).Selection criteriaCohort studies reporting placental anomalies in ART and non‐ART singleton pregnancies.Data collection and analysisWe report pooled odds ratios (OR) for the comparisons: (1) ART versus SC (spontaneously conceived), (2) ART versus non‐ART (unspecified), (3) FET‐ART (frozen‐embryo transfer) versus SC, (4) ART versus non‐ART (subfertile patients). Study quality was assessed using a modified Newcastle –Ottawa scale.Main results33 low/moderate quality studies evaluated 124 215 ART and 6 054 729 non‐ART singleton pregnancies. Risk of placenta praevia, placental abruption and morbidly adherent placenta was higher in ART than SC pregnancies: odds ratio (OR) (OR 3.76, 95% CI 3.09‐4.59); (OR 1.87, 95% CI 1.70‐2.06) and (OR 2.27, 95% CI 1.79‐2.87) respectively. Risk of placenta praevia and placental abruption was higher in ART than in non‐ART (subfertile patients): (OR 2.51, 95% CI 2.12‐2.98) and (OR 1.61, 95% CI 1.33‐1.95) respectively. Results were similar when comparing ART with unspecified non‐ART pregnancies. Risk of placenta praevia was higher, but not significantly so, in FET‐ART than in SC pregnancies (OR 2.42, 95% CI 0.63–9.30).ConclusionsSingleton ART pregnancies are associated with an increased risk of placental anomalies compared with non‐ART singleton pregnancies.Tweetable AbstractA review of over 6 million singleton pregnancies finds increased risk of placental anomalies after ART.
A survey of Australian prosthodontists: the use of posts in endodontically treated teeth
Authors: Sambrook R , Burrow M 
Published: May 2018

AbstractBackgroundThis study aimed to gain insight into common practises of Australian prosthodontists when placing a post in an endodontically treated tooth (ETT).MethodsA 17‐question open‐ and closed‐format questionnaire was sent to registered Australian prosthodontists. The response rate was 55% (N = 95).ResultsThe majority of respondents indicated the purpose of a post was to retain a core (N = 94, 99%). The decision to place a post is affected by the quantity of remaining tooth structure (N = 91, 96%) and the definitive restoration (N = 68, 72%). The ideal post length is neither a short nor long post with the most frequent response (N = 52, 34%) being ‘as long as possible without disturbing the apical seal’. The apical seal requirements were defined as 4–5 mm of gutta‐percha for 77% of respondents. The most preferred post type was a custom cast metal post (N = 85, 49%). The most popular luting cement was resin composite (N = 84, 39%).ConclusionsThe results from this survey do not provide a definitive guide for restoring an ETT. However, it illustrates how Australian prosthodontists address this clinical challenge. The multiple responses received for a number of questions suggest that the material and technique employed in the Australian context is influenced by the individual clinical case.

SummaryTreatment of Burkitt lymphoma (BL) with intensive, multi‐agent chemotherapy with aggressive central nervous system (CNS) prophylaxis results in high cure rates, although no regimen is standard of care. We examined population‐based survival outcomes of adults with BL treated with a modified combination of cyclophosphamide, vincristine, doxorubicin, prednisone and systemic high‐dose methotrexate (MTX) (CODOX‐M) with IVAC (ifosfamide, mesna, etoposide, cytarabine and intrathecal MTX) (CODOX‐M/IVAC) ± rituximab over a 15‐year period in British Columbia. For the 81 patients identified (including 8 with CNS involvement and 18 with human immunodeficiency virus‐associated BL), 5‐year progression‐free survival (PFS) and overall survival (OS) were 75% [95% confidence interval (CI): 63–83%] and 77% (95% CI: 66–85%), respectively, with no treatment‐related deaths. Those who completed the regimen per protocol (n = 38) had significantly improved 5‐year PFS 86% (P = 0·04) and OS 92% (P = 0·008), as did those under 60 years with 5‐year PFS 82% (P = 0·005) and OS 86% (P = 0·002), which remained significant in multivariate analysis [PFS: hazard ratio (HR) 3·36, P = 0·018; OS HR 4·03, P = 0·012]. Incorporation of high‐dose systemic methotrexate also significantly affected multivariate survival outcomes (OS HR 0·28, P = 0·025). Stem cell transplant in first remission had no effect on OS or PFS. This large, real‐world analysis of BL patients treated with CODOX‐M/IVAC ± rituximab demonstrates excellent survival outcomes comparable to clinical trials. These results help to serve as a benchmark when comparing curative therapies for BL patients as novel regimens are incorporated into clinical practice.
