The mediating role of perceived fairness in consumers’ response to post-purchase ‘out of stock’ in an online grocery context

This study investigates consumer response to a retailer’s substitution policy when facing post-purchase ‘out of stock’ (OOS) in an online grocery shopping context. Substitution policies (timeliness of OOS notification; and substituted product) can have detrimental effects on consumers’ satisfaction with the retailer and behaviour response (whether to accept or reject the substitution). As post-purchased OOS indicates a failure of service, the study focuses its investigation on the mediating effects of perceived fairness (PF) of retailers’ substitution policies on consumers’ response. It is predicted that procedural fairness will have a stronger effect on mitigating consumers’ negative OOS experience than distributive (outcome) fairness. The research will be conducted using three online scenario based experiments

Developing an interactive electronic maternity record

Women have a strong need to be involved in their own maternity care. Pregnancy hand-held records encourage women's participation in their maternity care; gives them an increased sense of control and improves communication among care providers. They have been successfully used in the UK and New Zealand for almost 20 years. Despite evidence that supports the use of hand-held records, widespread introduction has not occurred in Australia. The need for an electronic version of pregnancy hand-held records has become apparent, especially after the introduction of the Electronic Medical Record in Australia. A personal digital assistant (PDA) was developed as an interactive antenatal electronic maternity record that health-care providers could use in any setting and women could access using the internet. This article will describe the testing of the antenatal electronic maternity record

Self-branding and content creation strategies on Instagram: A case study of foodie influencers

The purpose of this study is to better understand the processes and procedures adopted by micro-influencers to create ‘Instagrammable’ content. It is based on 17 in-depth interviews with foodie micro-influencers based in London and Barcelona. Interview data was complemented with participant observation in restaurants or cafes. This paper makes three original contributions. Firstly, the study expands the understanding of the concept of ‘instagrammability’ by approaching it from the perspective of influencers creating content to satisfy and/or growan audience. Secondly, it illustrates how two dominant factors drive influencers content creation process: the self/audience focus content branding orientation. The the audience-focus content development process varied drastically, with some influencers being very conscious of responding to their audiences’ needs whereas others maintained first and foremost a very strong self-focus’. However, even for the influencers who were the most responsive to their audiences perceived wishes, a sense of self-focus was maintained as an anchor point in all developed content, often linked to a passion for a certain type of food. Thirdly, this paper maps and describes the behind-the-scenes content creation process adopted by micro-influencers, including four stages (1)Content Planning,(2)Media Gathering, (3)Editing,and (4)Publishing, which was followed by an engagement phase.This study offers a timely contribution to better comprehending the content creation cycle adopted by micro-influencers by using foodie influencers as a case study

‘With a little help from my friends’: exploring mutual engagement and authenticity within foodie influencers’ communities of practice

The aim of this paper is to analyze the dynamics of mutual engagement within the foodie influencer communities of practice created via Instagram. The study is based on 20 in-depth interviews with foodie Instagrammers. Findings demonstrate that unlike other communities of practice, rather than competing among themselves, foodies learn from each other, exchange tips, help those starting out in the field and attend events together. Close collaboration also leads to the formation of strong friendship bonds. However, findings show that whilst authenticity of content is deemed important, elements of influencer engagement are artificially orchestrated within their own community of practice. These findings have implications for marketing professionals in terms of evaluating influencersʻ engagement authenticity and the selection criteria they consider with regard to targeting appropriate and specific influencers to work with

Synthesis and characterization of hybrid organic-inorganic materials based on sulphonated polyamideimide and silica

The preparation of hybrid organic–inorganic membrane materials based on a sulphonated polyamideimide resin and silica filler has been studied. The method allows the sol–gel process to proceed in the presence of a high molecular weight polyamideimide, resulting in well dispersed silica nanoparticles (<50 nm) within the polymer matrix with chemical bonding between the organic and inorganic phases. Tetraethoxysilane (TEOS) was used as the silica precursor and the organosilicate networks were bonded to the polymer matrix via a coupling agent aminopropyltriethoxysilane (APTrEOS). The structure and properties of these hybrid materials were characterized via a range of techniques including FTIR, TGA, DSC, SEM and contact angle analysis. It was found that the compatibility between organic and inorganic phases has been greatly enhanced by the incorporation of APTrEOS. The thermal stability and hydrophilic properties of hybrid materials have also been significantly improved

Comparison of minimally invasive surgical approaches for hysterectomy at a community hospital: robotic-assisted laparoscopic hysterectomy, laparoscopic-assisted vaginal hysterectomy and laparoscopic supracervical hysterectomy

The study reported here compares outcomes of three approaches to minimally invasive hysterectomy for benign indications, namely, robotic-assisted laparoscopic (RALH), laparoscopic-assisted vaginal (LAVH) and laparoscopic supracervical (LSH) hysterectomy. The total patient cohort comprised the first 237 patients undergoing robotic surgeries at our hospital between August 2007 and June 2009; the last 100 patients undergoing LAVH by the same surgeons between July 2006 and February 2008 and 165 patients undergoing LAVHs performed by nine surgeons between January 2008 and June 2009; 87 patients undergoing LSH by the same nine surgeons between January 2008 and June 2009. Among the RALH patients were cases of greater complexity: (1) higher prevalence of prior abdominopelvic surgery than that found among LAVH patients; (2) an increased number of procedures for endometriosis and pelvic reconstruction. Uterine weights also were greater in RALH patients [207.4 vs. 149.6 (LAVH; P < 0.001) and 141.1 g (LSH; P = 0.005)]. Despite case complexity, operative time was significantly lower in RALH than in LAVH (89.9 vs. 124.8 min, P < 0.001) and similar to that in LSH (89.6 min). Estimated blood loss was greater in LAVH (167.9 ml) than in RALH (59.0 ml, P < 0.001) or LSH (65.7 ml, P < 0.001). Length of hospital stay was shorter for RALH than for LAVH or LSH. Conversion and complication rates were low and similar across procedures. Multivariable regression indicated that LAVH, obesity, uterine weight ≥250 g and older age predicted significantly longer operative time. The learning curve for RALH demonstrated improved operative time over the case series. Our findings show the benefits of RALH over LAVH. Outcomes in RALH can be as good as or better than those in LSH, suggesting the latter should be the choice primarily for women desiring cervix-sparing surgery

Mouse Middle Ear Ion Homeostasis Channels and Intercellular Junctions

The middle ear contains homeostatic mechanisms that control the movement of ions and fluids similar to those present in the inner ear, and are altered during inflammation.The normal middle ear cavity is fluid-free and air-filled to allow for effective sound transmission. Within the inner ear, the regulation of fluid and ion movement is essential for normal auditory and vestibular function. The same ion and fluid channels active in the inner ear may have similar roles with fluid regulation in the middle ear.Middle and inner ears from BALB/c mice were processed for immunohistochemistry of 10 specific ion homeostasis factors to determine if similar transport and barrier mechanisms are present in the tympanic cavity. Examination also was made of BALB/c mice middle ears after transtympanic injection with heat-killed Haemophilus influenza to determine if these channels are impacted by inflammation.The most prominent ion channels in the middle ear included aquaporins 1, 4 and 5, claudin 3, ENaC and Na(+),K(+)-ATPase. Moderate staining was found for GJB2, KCNJ10 and KCNQ1. The inflamed middle ear epithelium showed increased staining due to expected cellular hypertrophy. Localization of ion channels was preserved within the inflamed middle ear epithelium.The middle ear epithelium is a dynamic environment with intrinsic mechanisms for the control of ion and water transport to keep the middle ear clear of fluids. Compromise of these processes during middle ear disease may underlie the accumulation of effusions and suggests they may be a therapeutic target for effusion control

ZD6474 – a novel inhibitor of VEGFR and EGFR tyrosine kinase activity

Angiogenesis is crucial for maintaining the supply of oxygen and nutrients required to support solid tumour growth. Inhibitors of tumour blood vessel formation are therefore being sought, in particular, inhibitors of vascular endothelial growth factor-A (VEGF)-signalling, which has a pivotal role in stimulating neovascular growth and survival. ZD6474 is an orally bioavailable inhibitor of VEGF receptor-2 tyrosine kinase activity that in preclinical studies has been shown to inhibit both VEGF-induced signalling in endothelial cells and tumour-induced angiogenesis. Consistent with inhibition of angiogenesis, once-daily oral dosing of ZD6474 produced significant broad-spectrum antitumour activity in a panel of histologically diverse human tumour xenografts. In addition to its antiangiogenic properties, ZD6474 also has activity against the epidermal growth factor receptor (EGFR) tyrosine kinase, which could impart a direct inhibitory effect on tumour cell growth and survival. This may be particularly relevant in tumours with a dependency upon EGFR signalling, for example in certain tumours harbouring activating mutations in EGFR. RET kinase has also been identified as a third target for ZD6474. This review summarises preclinical studies with this unique agent and considers its future direction in cancer treatment
