Exploring customers’ zone of tolerance for B2B professional service quality
Purpose: This paper aims to extend the current research on zone of tolerance (ZOT) and its antecedents, to the context of business-to-business (B2B) professional services from both client and service firms’ perspectives, with a modified ZOT framework including five client and service firms attributes as antecedents of desired (DSL) and adequate (ASL) service levels. Prior research on zone of tolerance (ZOT) and its antecedents mostly focuses on business-to-consumer services and customers’ perspective. The authors address these gaps with a modified ZOT framework with five attributes of client and service firms as antecedents of customer expectations, namely, desired service level (DSL) and adequate service level (ASL), for business-to-business (B2B) professional services. Design/methodology/approach: A combination of qualitative (focus groups) and quantitative (online survey) research methods with managers of professional audit firms and their clients, using a reduced AUDITQUAL instrument with 39 items and seven dimensions.Findings: Professional firm size and fee premium have a positive effect on DSL; service tenure positively influences both DSL and ASL; client firm size has a negative effect on DSL; both client and service firm sizes positively moderate each other’s influence on the DSL; and DSL positively influences ASL. Research limitations/implications: The authors study a single B2B professional service (audit) in a single city (Hong Kong) from a single perspective (customers) that may limit the generalizability of the findings. Future research should validate the findings for other B2B professional services in diverse locations and also include service providers’ expectations and perceptions. Practical implications: Managers in professional service firms should understand the factors influencing different levels of expectations for their customers and develop suitable strategies (e.g. customer education and employee training) to manage these expectations more effectively. Originality/value: The authors extend current research on customer expectations and ZOT by identifying five unique attributes of professional service and client firms and testing their roles as antecedents of adequate and DSLs using AUDITQUAL instrument
'Happy-Performing Managers’ thesis: Testing the Mediating Role of Job-related Affective Outcomes on the Impact of Role-Stressors on Contextual Performance
Purpose –This study extends the ‘Happy-Performing Managers’ thesis to show that managers’ job-related affective wellbeing and affective job satisfaction mediate the impact of their role stressors (ambiguity, conflict, and overload) on their contextual job performance. Design/methodology/approach – Results from an online survey of 305 managers from the private, public and third sectors in Western Australian support most of the hypotheses. The psychometric properties of all the scales were analysed using Confirmatory Factor Analysis and the conceptual model was tested using Structural Equation Modelling. Findings – Role stressors have a direct negative effect on the managers’ affective wellbeing and affective job satisfaction, which in turn mediate the negative effects of the three role stressors on the managers’ contextual performance. Research limitations/implications – Conceptual and managerial contributions along with methodological limitations and future research directions are discussed. Originality/value – Contemporary managers face a wide-range of intrinsic and extrinsic role and environmental stressors. This research suggests that organisations may need to redesign manager roles to reduce their role stressors (ambiguity, conflict and overload) in order to optimize their contextual performance
Marine benthic flora and fauna of Gourdon Bay and the Dampier Peninsula in the Kimberley region of North-Western Australia
Surveys undertaken to characterise the marine benthic habitats along the Dampier Peninsula and further south at Gourdon Bay in the Kimberley region of Western Australia were augmented with epibenthic sled sampling of soft and hard bottom habitats. This paper describes the species collected, their biomass and relative abundance for the main groups of marine macrophytes and invertebrates. Five localities were surveyed; Gourdon Bay, Quondong Point to Coulomb Point, Carnot Bay to Beagle Bay, Perpendicular Head and Packer Island. Sampling was limited to fifteen epibenthic dredge operations from a range of habitat types and was designed to target the most common habitat types and to obtain species identifications of the most important species and those which typified different habitat types. Surveys covered a total of 1,350 m 2 of seabed in depths between 11 and 23m. We identified 415 taxa comprising: 1 seagrass, 43 algae, 52 sponges, 30 ascidians, 10 hydroids, 14 scleractinian corals, 52 other cnidarians, 69 crustaceans, 73 molluscs and 71 echinoderms. Despite the limited nature of the sampling, a significant number of new species, range extensions and new records for Western Australia and Australia were recorded. Within the algae, one range extension (Halimeda cf. cuneata f. digitata not previously recorded in Western Australia) and one possible new species of Areschougia were recorded. Two range extensions were present in the ascidians; the solitary ascidian Polycarpa cf. intonata has previously only been recorded in Queensland and Cnemidocarpa cf. radicosa only in temperate Australian waters. There were several range extensions for the crustacea, for example, the sponge crab, Tumidodromia dormia, has only been recorded in Queensland. One species of holothurian of the genus Phyllophorus could not be identified from the literature available and may represent a new species. Similarly, a small species of the echinoid Gymnechinus could possibly be a new species. The collections of hydroids, hard corals, crinoids and molluscs contained no new species or range extensions. There was difficulty in identification of some groups to species level due to the status of the current taxonomic literature (e.g. Cnidaria, Porifera and ascidians) and there may be a number of new species among the material collected. Among the anthozoa, there is at least one new species of Chromonephthea and potentially 10 range extensions to Western Australia. Sinularia cf. acuta and Chromonephthea curvata are both new records for Australia with both previously recorded in Indonesia only. Among the better known taxa (e.g. molluscs, echinoderms, corals), most of the taxa identified to species level have been recorded to occur throughout north-western Australia, however the diversity recorded in this study is less than other parts of the Kimberley and this is almost certainly a result of the small overall area sampled and the single method of collection utilised. The most important species on soft bottom habitats in terms of biomass was the heart urchin Breynia desorii (up to 326 g.m -2). Sponges were the dominant fauna by biomass (up to 620 g.m -2) on hard bottom habitats and biomass was dominated a by a few large cup and massive sponge species (e.g. Pione velans and two unidentified Spheciospongia). The biomass of other filter feeders, especially ascidians (e.g. Aplidium cf. crateriferum), soft corals (e.g. Chromonephthea spp.), gorgonians (e.g. Junceella fragilis and Dichotella gemmacea) was also high, indicating the importance of these groups in characterising hard bottom habitats. Although low in biomass, crinoids such as Comaster multifidus and Comatula pectinata were abundant in samples that included a high biomass of other filter feeders
Genetic diversity of Brazilian isolates of feline immunodeficiency virus
We isolated Feline immunodeficiency virus (FIV) from three adult domestic cats, originating from two open shelters in Brazil. Viruses were isolated from PBMC following co-cultivation with the feline T-lymphoblastoid cell line MYA-1. All amplified env gene products were cloned directly into pGL8MYA. The nucleic acid sequences of seven clones were determined and then compared with those of previously described isolates. The sequences of all of the Brazilian virus clones were distinct and phylogenetic analysis revealed that all belong to subtype B. Three variants isolated from one cat and two variants were isolated from each of the two other cats, indicating that intrahost diversity has the potential to pose problems for the treatment and diagnosis of FIV infection

Content and quality of websites supporting self-management of chronic breathlessness in advanced illness: A systematic review
Chronic breathlessness is a common, burdensome and distressing symptom in many advanced chronic illnesses. Self-management strategies are essential to optimise treatment, daily functioning and emotional coping. People with chronic illness commonly search the internet for advice on self-management. A review was undertaken in June 2015 to describe the content and quality of online advice on breathlessness self-management, to highlight under-served areas and to identify any unsafe content. Google was searched from Sydney, Australia, using the five most common search terms for breathlessness identified by Google Trends. We also hand-searched the websites of national associations. Websites were included if they were freely available in English and provided practical advice on self-management. Website quality was assessed using the American Medical Association Benchmarks. Readability was assessed using the Flesch-Kincaid grades, with grade 8 considered the maximum acceptable for enabling access. Ninety-one web pages from 44 websites met the inclusion criteria, including 14 national association websites not returned by Google searches. Most websites were generated in the USA (n=28, 64%) and focused on breathing techniques (n=38, 86%) and chronic obstructive pulmonary disease (n=27, 61%). No websites were found to offer unsafe advice. Adherence to quality benchmarks ranged from 9% for disclosure to 77% for currency. Fifteen (54%) of 28 written websites required grade ≈ 3/49 reading level. Future development should focus on advice and tools to support goal setting, problem solving and monitoring of breathlessness. National associations are encouraged to improve website visibility and comply with standards for quality and readability
Selective expansion of viral variants following experimental transmission of a reconstituted feline immunodeficiency virus quasispecies
Following long-term infection with virus derived from the pathogenic GL8 molecular clone of feline immunodeficiency virus (FIV), a range of viral variants emerged with distinct modes of interaction with the viral receptors CD134 and CXCR4, and sensitivities to neutralizing antibodies. In order to assess whether this viral diversity would be maintained following subsequent transmission, a synthetic quasispecies was reconstituted comprising molecular clones bearing envs from six viral variants and its replicative capacity compared in vivo with a clonal preparation of the parent virus. Infection with either clonal (Group 1) or diverse (Group 2) challenge viruses, resulted in a reduction in CD4+ lymphocytes and an increase in CD8+ lymphocytes. Proviral loads were similar in both study groups, peaking by 10 weeks post-infection, a higher plateau (set-point) being achieved and maintained in study Group 1. Marked differences in the ability of individual viral variants to replicate were noted in Group 2; those most similar to GL8 achieved higher viral loads while variants such as the chimaeras bearing the B14 and B28 Envs grew less well. The defective replication of these variants was not due to suppression by the humoral immune response as virus neutralising antibodies were not elicited within the study period. Similarly, although potent cellular immune responses were detected against determinants in Env, no qualitative differences were revealed between animals infected with either the clonal or the diverse inocula. However, in vitro studies indicated that the reduced replicative capacity of variants B14 and B28 in vivo was associated with altered interactions between the viruses and the viral receptor and co-receptor. The data suggest that viral variants with GL8-like characteristics have an early, replicative advantage and should provide the focus for future vaccine development
Identifying the barriers and enablers to pallative care nurses\u27 recognition and assessment of delirium symptoms: A qualitative study
Context: Delirium is under-recognised by nurses, including those working in palliative care settings where the syndrome occurs frequently. Identifying contextual factors that support and/or hinder palliative care nurses’ delirium recognition and assessment capabilities is crucial, to inform development of clinical practice and systems aimed at improving patients’ delirium outcomes.
Objective: To identify nurses’ perceptions of the barriers and enablers to recognising and assessing delirium symptoms in palliative care inpatient settings.
Methods: A series of semi-structured interviews, guided by critical incident technique, were conducted with nurses working in Australian palliative care inpatient settings. A hypoactive delirium vignette prompted participants’ recall of delirium and identification of the perceived factors (barriers and enablers) that impacted on their delirium recognition and assessment capabilities. Thematic content analysis was used to analyse the qualitative data.
Results: Thirty participants from 9 palliative care services provided insights into the barriers and enablers of delirium recognition and assessment in the inpatient setting, that were categorised as patient and family, health professional and system level factors. Analysis revealed five themes, each reflecting both identified barriers and current and/or potential enablers: i) value in listening to patients and engaging families; ii) assessment is integrated with care delivery; iii) respecting and integrating nurses’ observations; iv) addressing nurses’ delirium knowledge needs and v) integrating delirium recognition and assessment processes.
Conclusions: Supporting the development of palliative care nursing delirium recognition and assessment practice requires attending to a range of barriers and enablers at the patient and family, health professional and system levels
End-of-Life Delirium: Issues Regarding Recognition, Optimal Management and the Role of Sedation in the Dying Phase.
CONTEXT:
In end-of-life care, delirium is often not recognized and poses unique management challenges, especially in the case of refractory delirium in the terminal phase. OBJECTIVES:
To review: delirium in the terminal phase context, specifically in relation to recognition issues; the decision-making processes and management strategies regarding its reversibility; the potential refractoriness of delirium to symptomatic treatment; and the role of sedation in refractory delirium. METHODS:
We combined multidisciplinary input from delirium researchers and knowledge users at an international delirium study planning meeting and relevant electronic database literature searches (Ovid Medline, Embase, PsycINFO and CINAHL) to inform this narrative review. RESULTS:
The overall management strategy for delirium at the end of life is directed by the patient\u27s prognosis in association with the patient\u27s goals of care. As symptoms of delirium are often refractory in the terminal phase, especially in the case of agitated delirium, the judicious use of palliative sedation is frequently required. However, there remains a lack of high level evidence for the management of delirium in the terminal phase, including the role of antipsychotics and optimal sedation strategies. For the family and health care staff, clear communication, education and emotional support are vital components to assist with decision making and direct the treatment care plan. CONCLUSION:
Further research on the effectiveness of delirium management strategies in the terminal phase for patients and their families is required. Further validation of assessment tools for diagnostic screening and severity measurement are needed in this patient population
Role of Symbiotic Auxotrophy in the Rhizobium-Legume Symbioses
Symbiotic auxotrophy occurs in both determinate pea and indeterminate bean nodules demonstrating its importance for bacteroid formation and nodule function in legumes with different developmental programmes. However, only small quantities of branched chain amino acids are needed and symbiotic auxotrophy did not occur in the Sinorhizobium meliloti-alfalfa symbiosis under the conditions measured. The contrasting symbiotic phenotypes of aap bra mutants inoculated on different legumes probably reflects altered timing of amino acid availability, development of symbiotic auxotrophy and nodule developmental programmes
