Unraveling the diverse nature of service quality in a sharing economy: a social exchange theory perspective of Airbnb accommodation

This is an accepted manuscript of an article published by Emerald in International Journal of Contemporary Hospitality Management on 11/09/2017, available online: https://doi.org/10.1108/IJCHM-08-2016-0420 The accepted version of the publication may differ from the final published version.Purpose- This study investigates customers’ perceptions of the service quality facets of Airbnb accommodation using social exchange theory as a suitable conceptual framework to explain aspects of interactivity between guests and hosts. Design/methodology/approach- A self-administered questionnaire consisting of 25 accommodation- specific service quality attributes, structured according to Akbaba’s (2006) measurement scale and based on the service quality hierarchical conceptualization described by Brady and Cronin (2001) and Cronin and Taylor (1992), was distributed to Airbnb international guests visiting Phuket, Thailand. The sample was chosen through a two-stage sampling process and the PLS-SEM technique was used for data analysis. Findings- The results showed that convenience and assurance are critical contributors to the measurement of service quality in remote Airbnb lodgings. The findings further revealed that Airbnb guests are mainly interested in lodgings which have access to certain tourist sights, and in easily accessible information and efficient resolution of problems during their stay. We also found that guests greatly value the convenience and flexibility offered by Airbnb, and that they particularly appreciate the warm hospitality provided by the hosts. Finally, Airbnb guests have very low expectations of the amenities and services available at the lodgings. Research limitations/implications-Airbnb is one of the most well-known examples of hospitality in the sharing economy and results cannot be generalized to similar accommodation providers in sharing economies. Despite the appropriateness of using the measurement tool provided by Akbaba (2006), it is only one option among others for measuring service quality. Practical implications- The current study can assist hosts in gaining better knowledge of guests’ decision making processes and in designing effective marketing strategies by focusing on guests’ requirements in terms of service quality. The effective use of competitive strengths and the prioritization of business resources would potentially enhance guests’ positive experiences at the accommodation and at the destination. Originality/value-Limited numbers of studies have focused on the sharing economy and hospitality and in particular on Airbnb and this is the first study with a focus on service quality issues in terms of Airbnb accommodation

True substrates: The exceptional resolution and unexceptional preservation of deep time snapshots on bedding surfaces

Abstract: Rock outcrops of the sedimentary–stratigraphic record often reveal bedding planes that can be considered to be true substrates: preserved surfaces that demonstrably existed at the sediment–water or sediment–air interface at the time of deposition. These surfaces have high value as repositories of palaeoenvironmental information, revealing fossilized snapshots of microscale topography from deep time. Some true substrates are notable for their sedimentary, palaeontological and ichnological signatures that provide windows into key intervals of Earth history, but countless others occur routinely throughout the sedimentary–stratigraphic record. They frequently reveal patterns that are strikingly familiar from modern sedimentary environments, such as ripple marks, animal trackways, raindrop impressions or mudcracks: all phenomena that are apparently ephemeral in modern settings, and which form on recognizably human timescales. This paper sets out to explain why these short‐term, transient, small‐scale features are counter‐intuitively abundant within a 3.8 billion year‐long sedimentary–stratigraphic record that is known to be inherently time‐incomplete. True substrates are fundamentally related to a state of stasis in ancient sedimentation systems, and distinguishable from other types of bedding surfaces that formed from a dominance of states of deposition or erosion. Stasis is shown to play a key role in both their formation and preservation, rendering them faithful and valuable archives of palaeoenvironmental and temporal information. Further, the intersection between the time–length scale of their formative processes and outcrop expressions can be used to explain why they are so frequently encountered in outcrop investigations. Explaining true substrates as inevitable and unexceptional by‐products of the accrual of the sedimentary–stratigraphic record should shift perspectives on what can be understood about Earth history from field studies of the sedimentary–stratigraphic record. They should be recognized as providing high‐definition information about the mundane day to day operation of ancient environments, and critically assuage the argument that the incomplete sedimentary–stratigraphic record is unrepresentative of the geological past

An outpatient nursing nutritional intervention to prehabilitate undernourished patients planned for surgery : A multicentre, cluster-randomised pilot study

Background & aims: To improve the nutritional status of surgical patients before hospital admission, an Outpatient Nursing Nutritional Intervention (ONNI) was developed. The ONNI comprehends five components: determining causes of undernutrition, performing a nutritional care plan including tailored and general advice, self-monitoring of nutritional intake and eating patterns, counselling and encouragement, and conducting a follow-up telephone call to discuss improvements in nutritional behaviour. Here, we evaluate the feasibility and effectiveness of the ONNI. Methods: In a multi-centred, cluster-randomised pilot study, nurses from outpatient clinics were randomly allocated to usual care (UC) or the ONNI. Patients planned for elective surgery were included if they were at increased risk for undernutrition based on the Malnutrition Universal Screening Tool (MUST) and hospital admission was not planned within seven days. Feasibility outcomes included participation rate, extent of intervention delivery, and patient satisfaction. Nutritional intake was monitored for two days before admission. Body weight, BMI and MUST scores at hospital admission were compared to measurements from the outpatient clinic visit. Data were analysed on an intention-to-treat basis by researchers who were blinded for patients and caregivers. Results: Forty-eight patients enrolled the feasibility phase. Participation rate was 72%. Nurses delivered all intervention components adequately in the end of the implementation period. Finally, 152 patients (IG: n = 66, 43%) participated in the study. A significant difference in mean energy intake (870 kcal/d, 95%CI:630-1109 p < 0.000) and mean protein intake (34.1 g/d, 95%CI: 25.0–43.2; p < 0.000) was observed in favour of the IG. Nutritional energy requirements were achieved in 74% (n = 46) of the IG and in 17% (n = 13) of the UC group (p < 0.000), and protein requirements were achieved in 52% (n = 32) of the IG, compared to 8% (n = 6) of the UC group (p < 0.000). Body weight, BMI and MUST scores did not change in either group. Conclusions: The ONNI is a feasible and effective intervention tool for nurses at outpatient clinics. Patients in the IG had more nutritional intake and fulfilled nutritional requirements significantly more often than patients receiving UC. Further research is required to determine the optimal pre-operative timing of nutritional support and to measure its effect on other patients groups. Clinical trial registration: The study protocol was registered at the ClinicalTrial.gov website with the following identifier: NCT02440165.</p

U–Pb dating of cements in Mesozoic ammonites

Dating sedimentary carbonates using the U-Pb method can help improve the Phanerozoic timescale. Using a novel combination of laser-ablation, multi-collector, inductively-coupled-plasma, mass-spectrometry (LA–MC–ICP–MS) and thermal ionization multi-collector mass spectrometry (TIMS), U-Pb numerical ages were obtained on early-diagenetic calcite cements in Jurassic ammonites in which concentrations of U range from 0.47 to 5.3 ppm. The calcite cements of two ammonites, IS1 and IS2, from the uppermost Bifrons Zone of the Toarcian (179–180 Ma) of the UK, gave TIMS-normalized LA U–Pb dates of 164.9 ± 5.3 Ma and 166.7 ± 4.8 Ma respectively. Normalizing LA–ICP–MC–MS data to an in-house calcite standard gave a more precise date of 165.5 ± 3.3 Ma for IS1 cement. An unzoned ammonite, SS2, of Bajocian age (168–170 Ma) yield a TIMS-normalized LA U–Pb age of 158.8 ± 4.3 Ma for its early-diagenetic cement. Both the combined LA–MC–ICP–MS and TIMS approach, and the use of a calcite laser ablation standard can result in accurate ages of cements with uncertainties of 2–3% (2σ). The later, however, is more efficient and precise. These U-Pb dates of cements are 10 to 20 Myr younger than the numerical ages of the biostratigraphic intervals from which the ammonites derive. The U-Pb dates are taken to represent the time at which the aragonite shell of the ammonite inverted to calcite and released its U to precipitate in a late-diagenetic alteration of early-diagenetic fringing cements. Concentrations of U and Pb in a range of other pristine biogenic carbonates were found too low (U < 0.01 ppm) for meaningful dating using laser ablation method

A context analysis on how oral care is delivered in hospitalised patients: A mixed-methods study

Aims and Objectives: To analyse oral care delivery in one hospital through exploring experiences from both nurses’ and patients’ perspectives and examining patients’ oral health. Background: Oral health problems are associated with undernutrition and other general health outcomes. Although oral care belongs to the essentials of nursing, it is often neglected. Improving oral health may require behaviour change of both nurses and patients. Defining tailored strategies need a clear view on the context. Design: A context analysis in one hospital using a convergent parallel mixed-methods design was reported following the EQUATOR guidelines using two checklists: COnsolidated criteria for REporting Qualitative research (qualitative research) and STROBE (observational research). Methods: Semi-structured interviews were conducted with 19 nurses and 11 patients. The topic list was based on the Integrated Change Model. Prospective oral examination was performed among 91 surgical patients using the Oral Health Assessment Tool (OHAT). Results: Nurses acknowledged that they did not prioritise oral care in daily practice. Furthermore, they lacked knowledge and skills to identify and provide care for oral problems. Nurses mentioned helpful resources to perform oral care, like standardised language and instruments. However, they had no access to or were unaware of them. Patients admitted that they did not prioritise oral care due to their sickness during hospitalisation, were unaware of the importance of oral care, but felt responsible for their oral care. The most prominent oral problems identified with the OHAT were unclean mouths (n = 75, 82%), unhealthy gum and tissues (n = 55, 60%) and dry mouth (n = 42, 46%). Conclusions: This context analysis identified inadequate oral care due to lack of positive attitude and knowledge in both nurses and patients, skills for nurses, and resources. Relevance to Clinical Practice: The behavioural factors indicate strategies for development of a multicomponent intervention to improve oral care in this hospital, nutritional status and general health outcomes.</p

Fasting habits over a 10-year period : An observational study on adherence to preoperative fasting and postoperative restoration of oral intake in 2 Dutch hospitals

Background: Since 1999, international guidelines recommend fasting from solid foods up to 6 hours and clear liquids up to 2 hours before surgery. Early recovery after surgery programs recommend restoration of oral intake as soon as possible. This study determines adherence to these guidelines up to 20 years after its introduction. Methods: A 2-center observational study with a 10-year interval was performed in the Netherlands. In period 1 (2009), preoperative fasting time was observed as primary outcome. In period 2 (2019), preoperative fasting and postoperative restoration of oral intake were observed. Fasting times were collected using an interview-assisted questionnaire. Results: During both periods, 311 patients were included from vascular, trauma, orthopedic, urological, oncological, gastrointestinal, and ear-nose-throat and maxillary surgical units. Duration of preoperative fasting was prolonged in 290 (90.3%) patients for solid foods and in 208 (67.8%) patients for clear liquids. Median duration of preoperative fasting from solid foods and clear liquids was respectively 2.5 and 3 times the recommended 6 and 2 hours, with no improvements from one period to another. Postoperative food intake was resumed within 4 hours in 30.7% of the patients. Median duration of perioperative fasting was 23:46 hours (interquartile range 20:00–30:30 hours) for solid foods and 11:00 hours (interquartile range 7:53–16:00 hours) for clear liquids. Conclusion: Old habits die hard. Despite 20 years of fasting guidelines, surgical patients are still exposed erroneously to prolonged fasting in 2 hospitals. Patients should be encouraged to eat and drink until 6 and 2 hours, respectively, before surgery and to restart eating after surgery.</p
