The locality of Beijing historic areas from a dynamic perspective based on geo-tagged photos
Authors: Wang Fang , Hu Wenying , Zhu Yicai , Jiang Chunyan 
Published: August 2018

PurposeDue to rapid development, historic city areas are faced with urbanization damage to their characteristic urban identity besides physical deterioration and economic decay. The purpose of this paper is to address the following questions: What are the constituent elements of locality for historic areas? How does one classify historic areas according to locality elements? What are the characteristics of each kind of historic area? How does one identify to-be-protected locality elements according to different historic areas to realize sustainable development?Design/methodology/approachAs a historic cultural city with a building history of over 3,000 years, Beijing has a myriad of distinctive historic areas, of which 367 were selected as the research samples. This paper classifies historic areas into the following four categories: distinctive areas, permanent areas, adaptive areas and inherited areas by analyzing the locality elements of 8,905 geo-tagged photos related to Beijing historic areas. The correlation among locality elements – the basis for joint protection – is also examined by Pearson’s correlation analysis.FindingsThe results are as follows: the reaction degree of carrier elements is generally higher than that of information elements, of which the representative architecture is the main constituent element of locality; folk customs, traditional activities and other intangible cultural heritage in historic areas receive only slight attention and need to be further stressed; controlled by non-human factors, permanent elements bear a high degree of autocorrelation; and emerging tourism and business activities have, to some extent, grown into constituent parts of the locality elements in historic areas.Originality/valueThis paper seeks to strike a dynamic balance between city renewal and historic area protection, providing a reference for understanding the dynamics of locality.

Published: August 2018

PurposeThe purpose of this paper is to propose a dedication-constraint-temptation (DCT) model to study the factors influencing customers’ loyalty to mobile data service (MDS) providers. The DCT model explicitly explores the important yet overlooked role of alternative attractiveness (the temptation-based mechanism) as a mediator and the boundary condition of their interrelationships (e.g. relationship length). The model also integrates new and established antecedents of customer-based brand equity (C-BBE) (the dedication-based mechanism) and switching barriers (the constraint-based mechanism).Design/methodology/approachThe proposed model is tested using partial least squares–structural equation modeling with a sample of 331 MDS users.FindingsThe results indicate that C-BBE has an indirect effect on customer loyalty (via alternative attractiveness) in both relationship groups (shorter- vs longer-term). However, the indirect effect of switching barriers on customer loyalty only exists in longer established relationships. The results from multi-group analysis reveal that the effect of switching barriers on alternative attractiveness significantly differs across groups. In addition, customer value anticipation and procedural switching costs appear to be the most salient antecedents of C-BBE and switching barriers for both groups.Originality/valueThis study makes an incremental contribution by incorporating the temptation-based mechanism as a mediator and relationship length as a moderator into the dedication-constraint model. This study also extends the information systems and brand management literatures by demonstrating the strategic importance of customer value anticipation in the information and communication technology brand equity-building.
The impact of manager training on employee turnover intentions
Authors: Malek Kristin , Kline Sheryl Fried , DiPietro Robin 
Published: August 2018

PurposeThere are decades of research analyzing turnover in the hospitality industry and yet it remains nearly double other industries. Whereas previous studies have analyzed training and its impact on turnover, the purpose of this paper is to look at the direct relationship between training at the management level and how this impacts their direct employees’ turnover intentions.Design/methodology/approachThis study utilized annual evaluation data from two luxury resorts in the southeast USA. Exploratory factor analysis was conducted which resulted in four factors: management style, manager/employee relations, manager training and employee turnover intentions. Multiple regression was utilized to assess these relationships between factors.FindingsThe analyses show that an employee’s perception of his or her manager was inversely related to turnover intentions. Additionally, it was found that management training and management style had a significant inverse relationship with employee turnover intentions. Finally, this study found that as manager training increases, employee turnover intentions decrease. This research indicates that if hotels invest in management training then there will be a reduction in employee turnover intention.Research limitations/implicationsThe sample consisted of only two luxury full service hotels in the southeastern USA. Both luxury hotels recruited a significant amount of employees from local universities; therefore, the workforce was more educated than other hotels. This study should be replicated across hotel types and throughout various locations.Practical implicationsThis research has relevant implications for practitioners. General managers should analyze their training requirements and fiscal appropriations. This research finds that if hotels invest in management training then there will be a reduction in employee turnover. If managers had more training, this study indicates that employees would view their managers more favorably, feel closer to their managers and have less of a desire to leave the organization.Originality/valueExtant research has shown that employee training programs impact employee turnover and that manager training programs impact manager turnover. This study extends that research by showing that these segments are not autonomous; manager training has a significant direct effect on employee turnover intention. This has not been studied in turnover intention literature suggests that this could be the missing variable in the body of turnover research.
When territory matters: Employer associations and changing collective goods strategies
Authors: Sheldon Peter , Della Torre Edoardo , Nacamulli Raoul 
Published: August 2018

AbstractRecent research shows employer associations strategically responding to external challenges, from collective bargaining decentralisation, by altering their offerings of “selective” goods (to directly address threats to membership levels) and of “elective” goods (to revenues). Implicit is that traditional “collective goods” are irrelevant for achieving sustainability. That literature also suggests that territorial associations are more vulnerable than sectoral ones. In this qualitative, longitudinal comparative case study, we explore why and how two territorial associations, the largest each in Italy and Australia, have pursued sustainability by also innovatively enlarging their collective goods activities. This has involved shifting from bargaining leadership to promoting economic dynamism within their territories. Using metaorganisation theory and the resource‐based view, we explain how these associations realised their strategic advantages. Our evidence suggests that innovatively developing new collective goods may be another important way associations can improve their competitive positions.
“Pitfalls in relative abundance estimation using eDNA metabarcoding”
Authors: Fonseca Vera G. 
Published: August 2018

AbstractMetabarcoding provides unparalleled information of overall ecosystem ecology and diversity, from occurrence to relative abundances, from micro‐ to macro‐organisms, including cryptic species and larval stages that would otherwise be impossible to identify. PCR is still the most cost‐effective and routinely used method to extract information from environmental samples coupled with high‐throughput sequencing (HTS). Nichols et al. () metabarcoded nine soil environmental samples from Alaska and six mixtures of synthetic oligonucleotides, using a short fragment of the chloroplast trnL gene. The authors tested the effect of PCR replicates, different polymerase mixes and amplicon GC content on diversity estimates. Results show that occurrence data was not biased for any of the parameters tested and only insufficient PCR replicates could impair the detection of rare taxa. For abundance data, polymerases were found to differentially bias estimates of the relative amplicon abundances and this depended on GC content.

Published: August 2018

AbstractTwo new species of gall midges of the genus Dactylasioptera Kolesik & Veenstra‐Quah, (Lasiopteridi: Lasiopterini) are described from hairy stem tip galls on Maireana (Chenopodiaceae) in southern Australia. Dactylasioptera lebelae sp. nov. Veenstra & Kolesik, 2018 causes galls on Maireana pyramidata ranging from filamentous to spheroid. Dactylasioptera milnae sp. nov. Veenstra & Kolesik, 2018 causes rosette shaped, leafy galls on Maireana brevifolia. Descriptions of larvae, pupae, male and female adults, as well as geographical distributions of the new gall midges are given. The two species differ from each other in the larval, pupal and adult morphology as well as in mtDNA sequence data (COI). Galls of both species contained fungal mycelium and inquiline wasps Megastigmus sp. (Hymenoptera: Torymidae) and Aprostocetus sp. (Hymenoptera: Eulophidae: Tetrastichinae). The new species are the first confirmed gall makers from the Australian genus Dactylasioptera that contained previously two described species: Dactylasioptera adentata Kolesik & Veenstra‐Quah, and Dactylasioptera dentata Kolesik & Veenstra‐Quah, 2018, both of which are likely inquilines reared from galls induced by Asphondylia spp. (Diptera: Cecidomyiidae) on chenopod host plants. A matrix of morphological characters of Dactylasioptera species is given.
Suicidality among gambling helpline callers: A consideration of the role of financial stress and conflict
Authors: Carr Meagan M. , Ellis Jennifer D. , Ledgerwood David M. 
Published: August 2018

Background and ObjectivesHigh rates of suicidal ideation and attempts secondary to gambling are well established among those with gambling disorders. The present study explores potential risk factors for suicidal ideation and/attempt among a sample of help‐line callers.MethodsParticipants (N = 202) completed measures assessing demographics; gambling behavior; and financial, family/social, employment, substance use, and legal difficulties related to gambling. Bivariate analyses, logistic regression, and mediation analyses were used to explore relationship between predictors and risk of suicidal ideation and attempt.ResultsFemale gender, gambling severity (including engagement in illegal behaviors), a history of mental health problems, financial problems, and conflict related to gambling were associated with current suicidality in this sample. Mediation analyses revealed that financial problems were associated with increased familial conflict, which was in turn associated with increased suicidality.ConclusionsFamily and social conflict may be one important way in which financial problems confer risk for suicidality among problem gamblers. These results align with findings from the substance use disorder (SUD) literature and highlight one potential factor that may merit further assessment and/or intervention.Scientific SignificanceResearchers and clinicians may want to consider the overall level of conflict a patient is experiencing when assessing suicide risk among individuals with gambling problems. Professionals may also want to consider the suitability of interventions to address conflict within the context of gambling treatment. (Am J Addict 2018;27:531–537)

Published: August 2018

AbstractAimA top‐down approach is widely used for detecting vesicoureteral reflux (VUR) in children with febrile urinary tract infections. We evaluated the diagnostic value of renal scintigraphy in predicting VUR in children with antenatal hydronephrosis (AHN).MethodsThe voiding cystourethrogram (VCUG) and renal scintigraphy results of 125 AHN patients (76% male) admitted to the Children's Hospital of Helsinki University, Finland, from 2003 to 2013 were analysed. Of those, 94 had nonrefluxing hydronephrosis, nine had low‐grade VUR and 22 had high‐grade VUR.ResultsScintigraphy was performed at a median age of 1.4 (0.8–15.6) months. In patients with high‐grade VUR, the differential renal function (DRF) of the worse kidney was significantly lower than in patients without VUR, with a median of 35% and interquartile range (IQR) of 20–45 versus 47% (IQR: 44–49), (p < 0.001). There was no difference between patients with low‐grade VUR and patients without VUR (p = 0.181). DRFs below 44% showed a sensitivity of 73% and specificity of 79% and predicted significantly high‐grade VUR (odds ratio 9.82, 95% confidence interval 3.44–28.05, p < 0.001) in the univariate analysis.ConclusionA DRF below 44% predicted high‐grade VUR in patients with AHN and supported the decision to perform VCUG.

Published: August 2018

ObjectivesTo report outcomes from a multiparametric (mp) magnetic resonance imaging (MRI)‐based active surveillance programme that did not include performing protocol biopsies after the first confirmatory biopsy.Patients and MethodsAll patients diagnosed with Gleason 3 + 3 prostate cancer because of a raised PSA level who underwent mpMRI after diagnosis were included. Patients were recorded in a prospective clinical database and followed up with PSA monitoring and repeat MRI. In patients who remained on active surveillance after the first MRI (with or without confirmatory biopsy), we investigated PSA dynamics for association with subsequent progression. Comparison between first and second MRI scans was undertaken. Outcomes assessed were: progression to radical therapy at first MRI/confirmatory biopsy and progression to radical therapy in those who remained on active surveillance after first MRI.ResultsA total of 211 patients were included, with a median of 4.2 years of follow‐up. The rate of progression to radical therapy was significantly greater at all stages among patients with visible lesions than in those with initially negative MRI (47/125 (37.6%) vs 11/86 (12.8%); odds ratio 4.1 (95% CI 2.0–8.5), P < 0.001). Only 1/56 patients (1.8%) with negative initial MRI scans who underwent a confirmatory systematic biopsy had upgrading to Gleason 3 + 4 disease. PSA velocity was significantly associated with subsequent progression in patients with negative initial MRI (area under the curve 0.85 [95% CI 0.75–0.94]; P <0.001). Patients with high‐risk visible lesions on first MRI who remained on active surveillance had a high risk of subsequent progression 19/76 (25.0%) vs 9/84 (10.7%) for patients with no visible lesions, despite reassuring targeted and systematic confirmatory biopsies and regardless of PSA dynamics.ConclusionMen with low‐risk Gleason 3 + 3 prostate cancer on active surveillance can forgo protocol biopsies in favour of MRI and PSA monitoring with selective re‐biopsy.

Published: August 2018

AbstractBackgroundDrug‐induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DiHS/DRESS) is a distinct phenotype of severe drug eruptions characterized by sequential reactivations of herpesviruses. Although a progressive loss of suppressive function in regulatory T cells (Tregs) occurred during the course of DiHS/DRESS, but not in Stevens‐Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), no previous studies investigated the mechanism. Given the recent finding that Treg development could be differentially regulated by CD16+ patrolling monocytes (pMOs) and CD14+ classical monocytes (cMOs), we can hypothesize that a differential fine‐tuned interaction between Tregs and monocytes is the driving force behind the possible shift from Tregs to Th17 cells over a prolonged period of time in DiHS/DRESS.ObjectiveTo investigate whether the shift from Treg to Th17 could specifically occur during the course of DiHS/DRESS and to elucidate which subsets of monocytes could be involved in the shift.MethodsWe performed a prospective longitudinal study on the frequencies of Tregs, Th17 cells and monocyte subsets after onset of DiHS/DRESS and SJS/TEN, and long after their clinical resolutions. We next examined whether pMOs and cMOs could have a strong impact on the Th17/Treg differentiation and which cytokines could be crucial for the interaction between Th17/Tregs and MO subsets, by in vitro cocultures.ResultsSelective depletion of pMOs occurring at the acute stage of DiHS/DRESS was associated with the relative increase in the frequencies of cMOs producing IL‐10 and it did drive Treg expansions. After clinical resolution, pMOs producing IL‐6 were alternatively recruited and contributed to the eventual shift from a Treg to Th17 responses.Conclusions and Clinical RelevanceThe gradual shift from Treg to Th17 cell development observed during the clinical course of DiHS/DRESS is mediated by the predominance of cMOs at the acute stage and alternatively recruited pMOs at the resolution stage, respectively.
Cancer and dementia: Two sides of the same coin?
Authors: van der Willik Kimberly D. , Schagen Sanne B. , Ikram M. Arfan 
Published: August 2018

AbstractNoncentral nervous system cancer and the brain share an interesting and complex relation, with an emerging body of evidence showing that cancer patients are at an increased risk of developing cognitive problems. In contrast, population‐based studies consistently find an inverse link between cancer and dementia, that is patients with dementia having a lower risk of subsequently developing cancer, and cancer patients being less often diagnosed with dementia. Different biological processes such as inversely activated cell proliferation and survival pathways have been suggested to have an important role underlying this inverse association. However, the effect of methodological biases including surveillance or survival bias has not been completely ruled out, calling into question the inverse direction of the association between cancer and dementia. In fact, emerging evidence now suggests that cancer and dementia might share a positive association. This narrative review summarises the current literature on cancer, cognitive problems and dementia. Moreover, different strategies will be discussed to reduce the impact of potential methodological biases on the association between cancer and dementia, trying to reveal the true direction of this link.
Hypothermia prevention in long‐standing equine dental procedures
Authors: Florczyk A. , Simhofer H. , Rosser J. 
Published: August 2018

SummaryHypothermia is a common, detrimental post‐operative complication in man and veterinary medicine. Active warming strategies are paramount for prevention and treatment. Duration of operations, administered drugs and their adverse effects put horses undergoing procedures requiring long‐standing sedation in danger of hypothermia. The aim of this study was to investigate whether an air warming device would be helpful to avoid severe hypothermia in adult horses. Twenty client‐owned horses undergoing dental/sinusoidal procedures were divided into two equal groups. The treatment group was covered with a warming blanket connected to the warming device with the temperature set to 43°C. Horses in the control group were not blanketed. Temperature was measured at the time of first sedation (T0) and every hour throughout the length of the procedure. Use of the warming blanket was straightforward and caused no adverse reactions. The mean decrease in body core temperature in the treatment group was significantly less than the mean temperature decrease in the control group, beginning at the second hour of the procedure. No horse in the treatment group reached a body temperature below 36°C. Overall loss of temperature in the control group was more than double when compared with the treatment group (1.5°C and 0.7°C respectively). The use of an active air warming blanket in horses is an easy technique to prevent hypothermia in horses undergoing long‐standing sedation procedures.
Ecosystem type shapes trophic position and omnivory in fishes

Published: August 2018

AbstractThe identification of patterns in ecological characteristics of organisms is a central challenge in macroecology with a growing research interest. The goal of this study was to establish whether patterns in trophic ecology (trophic position and omnivory) of fishes can be extended to an ecosystem dimension (freshwater vs. marine environments), based on the premise that differences in environmental and ecological conditions of aquatic ecosystems have a large influence on the feeding ecology of fishes. To elucidate any relationship between trophic ecology and ecosystem type, we compiled a database using a global data set for fishes (http://www.fishbase.org). The database included 5,426 species distributed in 53 orders based on three common feeding strategies (herbivory, filter‐feeding and predatory). Trophic position and omnivory increased from freshwater to marine ecosystems in filter‐feeding and predatory species. In herbivore species in contrast, omnivory decreased, whereas no statistically significant trends were found for trophic position, which may reflect a similar diet specialization on primary producers regardless of ecosystem type. These findings suggest that ecosystem type has a marked effect on trophic position and omnivory in fishes, but the impact depends on the type of feeding strategy. Prey availability, inherent feeding traits linked to the phylogenetic relatedness of species, ontogenetic effects, spatial variability (habitat‐related factors) and body size are considered as responsible factors for the observed patterns. Our findings demonstrate consistent patterns in trophic characteristics of organisms linked to ecosystem type and underline the usefulness of fishes as model organisms to test macroecology hypotheses.
