User Behaviors After Critical Mobile Application Incidents: The Relationship with Situational Context

Users occasionally have critical incidents with information systems (IS). A critical IS incident is an IS product or service experience that a user considers to be unusually positive or negative. Critical IS incidents are highly influential in terms of users’ overall perceptions and customer relationships; thus, they are crucial for IS product and service providers. Therefore, it is important to study user behaviors after such incidents. Within IS, the relationships between the situational context and user behaviors after critical incidents have not been addressed at all. Prior studies on general mobile use as a related research area have recognized the influence of the situational context, but they have not covered the relationships between specific situational characteristics and different types of user behaviors. To address this gap, we examine 605 critical mobile incidents that were collected from actual mobile application users. Based on our results, we extend current theoretical knowledge by uncovering and explaining the relationships between specific situational characteristics (interaction state, place, sociality, and application type) and user behaviors (use continuance, word-of-mouth, and complaints). We have found, for example, that users are less likely to engage in negative behaviors after negative incidents that take place outdoors or in vehicles than after indoor incidents. This is because users often consider indoor environments to be familiar and treat them with established expectations and low uncertainty: users are accustomed to the notion that the applications function indoors just like before. Further, we present practical implications for mobile application providers by suggesting to them which positive critical incidents are the most beneficial to promote and which negative critical incidents are the most crucial to avoid.
Age-related decline in VIP-positive parasympathetic nerve fibers in the human submacular choroid.

PURPOSE An age-related decline in macular choroidal blood flow (ChBF) occurs in humans. Vasodilatory nerve fibers containing vasoactive intestinal polypeptide (VIP) innervate choroidal blood vessels. The current study was conducted to examine the possibility that an age-related loss of these fibers might occur in the submacular choroid in humans, and thus contribute to a decline in ChBF. METHODS Macular choroid punches were collected from 35 healthy human donors ranging from 21 to 93 years of age. Choroidal samples were immunolabeled using anti-VIP and the peroxidase-antiperoxidase METHOD VIP-positive nerve fiber abundance was quantified in up to 12 fields per punch. Fifty macular punches were analyzed, and results for eye pairs were averaged. Choroidal vessel diameter (ChVD) was measured for these same fields. The relationship between age and vessel diameter or VIP-positive fiber abundance was analyzed. Multivariate statistical models were generated correcting for gender, variables related to the tissue specimens, and potential procedural sources of variability. RESULTS The fully adjusted multivariate models showed a significant age-related reduction in both the VIP-positive fiber abundance (P = 0.0003, adjusted R(2) = 0.51) and ChVD (P < 0.0001, adjusted R(2) = 0.63), with slopes of -0.45 and -0.19, respectively. Adjusting for the same variables, VIP-positive fiber abundance showed a significant direct correlation with ChVD. CONCLUSIONS The results indicate a significant age-related decline in VIP-positive nerve fibers and vessel diameter in the submacular choroid in disease-free human donor eyes. These findings suggest that a decline in the neural control of ChBF and vessel diameter may explain the reductions in ChBF and its adaptive control observed clinically with aging.
Evaluation of the autoSCAN-W/A system for rapid (2-hour) identification of members of the family Enterobacteriaceae

We evaluated the ability of the Baxter autoSCAN-W/A System (MicroScan Division, Baxter Diagnostics, Inc., West Sacramento, Calif.) to use the rapid (2-h) gram-negative identification panel for accurate identification of members of the family Enterobacteriaceae. At 2 h, 353 of 467 (75.6%) strains in a challenge set of biochemically typical and atypical stock cultures were correctly identified to genus and species. Another 76 (16.3%) strains were correctly identified to genus and species after the performance of recommended additional biochemical testing. Thus, at 24 h, 91.9% of the 467 strains were correctly identified. Twenty-two strains (4.7%) were identified to the correct genus but the incorrect species, and 16 strains (3.4%) were misidentified. Of these 16 strains, 9 were incorrect at 2 h, and 7 were incorrect after the additional testing. Because the system is based on fluorogenic substrates, no conventional tests were readily available with which to compare aberrant reactions. These results suggest that the autoSCAN-W/A with its rapid gram-negative panels is acceptable for the identification of the Enterobacteriaceae in a clinical microbiology laboratory.
Non‐invasive measurement of cardiac output by Finometer in patients with cirrhosis

The Finometer measures haemodynamic parameters including cardiac output (CO) using non‐invasive volume‐clamp techniques. The aim of this study was to determine the accuracy of the Finometer in hyperdynamic cirrhotic patients using an invasive indicator dilution technique as control. CO was measured in twenty‐three patients referred for invasive measurements of the hepatic venous pressure gradient on suspicion of cirrhosis. Invasive measurements of CO were performed using indicator dilution technique (COI) and simultaneous measurements of CO were recorded with the Finometer (COF). In six patients, measurements of CO were performed with invasive technique and the Finometer both before and after β‐blockade using 80 mg of propranolol and the changes in CO (ΔCOI and ΔCOF respectively) were calculated to evaluate the Finometers ability to detect relative changes in CO. Mean COI was 6·1 ± 1·6 [3·9;9·7] l min−1 (mean ± SD [range]) compared to mean COF of 7·2 ± 2·3 [3·1;11·9] l min−1. There was a mean difference between COF and COI of 1·0 ± 1·8 [−2·1;4·0] l min−1 and 95% confidence interval of [0·2;1·8], P<0·001. In patients with measurements before and after β‐blockade, mean ΔCOI was 1·6 ± 1·4 [−0·1;3·3] l min−1 compared to mean ΔCOF of 1·9 ± 1·3 [0·4;3·8] l min−1. Mean difference between ΔCOF and ΔCOI was 0·3 ± 0·3 [−0·2;0·7] l min−1 with a 95% confidence interval of [−0·1;0·6], P = 0·11. Compared with invasive measurements, the Finometer can be used to measure changes in CO, whereas absolute measurements are associated with higher variation in patients with cirrhosis. The Finometer seems useful for repeated determinations such as in studies of effect of pharmacotherapy.
Women, work and stress: a review and agenda for the future.

A review olfthe literature on women and work-related stress was conducted to identify conclusions regarding the link betw een job conditions conducive to stress and disease outcomes, and to suggest directions fr jfiture research. Defined as an imbalance between perceived demand and pe)-ceived capability, stress is viewed as an intervening variable between conditions c(onducil'e to stress, and responses and the more enduring disease outcomes. Research findings tire inconclusilve but suggest that work may have a beneficial effect on mental health, and that certain tvpes of-jobs in combination with family responsibilities may lead to increased risk or actual development of 'cardiovascular disease. However, studies on women lacked specificity on Work environment and onfamily responsibilitieslattitudes. Future research on women should involve (I) longitudinal studies before, during and after cessation of employment, (2) specificity about job environment and family responsibilities, (3) length and continuity of exposure to potentially stressful conditions, and (4) individual perceptions and coping responses.
E-WOM attractiveness, e-brand community trust, e-brand community experience and brand loyalty: a study on XIAOMI electronic brand community in Indonesia

This study discusses electronic brand community (e-brand community), especially Xiaomi online community in Indonesia. The goals of this research are (1) to analyse the influence of e-WOM attractiveness on e-brand community trust, (2) to analyse the Influence of e-brand community experience on e-brand community trust and brand loyalty, (3) to analyse e-brand community trust on brand loyalty. The research samples are 139 members of Xiaomi online community in Indonesia. The analysis used in this study is a structural equation modelling (SEM) with AMOS version 21 to process the data. The results show that only e-brand community experience is able to improve brand loyalty. E-WOM attractiveness is unable to improve e-brand community trust. Other results show that e-brand community experience has negative and insignificant influence on e-brand community trust, while e-brand community trust has positive but insignificant influence on brand loyalty. The research implications are: first, focus on building website in which there is an interactive forum. Second, strive to build an active participation of online community members. Third, as an effort for e-WOM attractiveness to raise online community members’ trust, the company needs to actively engage in any opinions made by the leaders of renowned ‘figures’ in community members and be actively involved in communication with this product communities.
Ultrastructural injury to interstitial cells of Cajal and communication with mast cells in Crohn's disease

Abstract Crohn's disease associated dysmotility has been attributed to fibrosis and damage to enteric nerves but injury to interstitial cells of Cajal (ICC) could also be involved. We assessed ICC in specimens obtained from patients with Crohn's disease and determined the relation between ICC and the inflammatory infiltrate, particularly mast cells (MC) using quantitative immunohistochemistry and electron microscopy. Ultrastructural injury to ICC was patchy in all ICC subtypes but ICC‐Auerbach's plexus (AP) showed damage more frequently, i.e. swelling of mitochondria, decreased electron density, autophagosomes and partial depletion of the cytoplasm. Light microscopy confirmed a significant decrease in c‐kit immunoreactivity for ICC‐AP and an increased number of MC in the muscularis externa. Electron microscopy showed MC exhibiting piecemeal degranulation and making frequent and selective membrane‐to‐membrane contact with all types of injured ICC which suggests chronic release of granule content to affect ICC. Extent of ICC injury was not associated with duration of the disease. In conclusion, ultrastructural injury and loss of ICC‐AP is evident in Crohn's disease. Epidemiological and morphological data suggest that ICC have the capacity to regenerate in spite of the chronic insult. The muscularis hosts a marked number of MC that exhibit piecemeal degranulation associated with ICC and may facilitate ICC maintenance.
Fibroblast growth factor 2 negatively regulates the induction of neuronal progenitors from neural stem cells

Fibroblast growth factor 2 (FGF2) exhibits pleiotropic functions during embryogenesis. In neural development, both pro‐ and antineurogenic activities of FGF2 have been described in the differentiation of neuronal progenitors into postmitotic neurons. We used cultured neural stem cells (NSCs) derived from rat embryonic day 14.5 cortex to determine the FGF2 effect on the induction of early neuronal progenitors. Our data showed that the presence of FGF2 during serum‐induced differentiation of NSCs reduced the number of Tuj1+ neurons. A bromodeoxyuridine (BrdU)/Tuj1 double‐labeling assay and expression analyses of the pro‐ and antineurogenic basic helix‐loop‐helix (bHLH) factors showed that FGF2 blocked the generation of early neuronal progenitors, but not the cell‐cycle exit of dividing neurons. This negative regulation of neuronal induction by FGF2 was associated with the persistent expression of an antineurogenic bHLH, hairy and enhancer of split (HES)‐1. A gene‐profiling study demonstrated that the developmental programs underlying neuronal differentiation were altered as a whole and identified several developmentally regulated, neural‐enriched genes. This work shows that FGF2 exerts an antineurogenic effect during the developmental window when neuronal progenitors are first induced from NSCs. It also provides a novel experimental system that can be used to prospectively identify genes expressed at different stages of neuronal differentiation. © 2005 Wiley‐Liss, Inc.
Improved understanding of Tasmanian harmful algal blooms and biotoxin events to support seafood risk management

This project was triggered by a toxic dinoflagellate bloom along the Tasmanian East coast in Oct 2012 that resulted in a $23M loss to the Tasmanian economy. A key deliverable will be development, testing, and calibration of rapid toxin screen tests ($15 each) using a platform similar to the home pregnancy test kit. This will provide an on-site tool to manage seafood harvest (e.g. avoid toxic scallop beds) and create a major cost-saving for the Tasmanian Shellfish Quality Assurance Program (TSQAP) by reducing submission of non-toxic samples for costly Sydney-based High-performance liquid chromatography (HPLC) analyses (7-10d turn around). This work will limit complete closures of fisheries, significantly reduce the risk of unsafe product reaching domestic and export markets, and thereby enhance the reputation of the Australian seafood industry.

Ecological conditions in wintering and passage areas as determinants of timing of spring migration in trans-Saharan migratory birds.

1. Climate change has been associated with shifts in the timing of biological events, including the spring arrival of migratory birds. Early arrival at breeding sites is an important life-history trait, usually associated with higher breeding success and therefore, susceptible to selection and evolution in response to changing climatic conditions. 2. Here, we examine the effect of changes in the environmental conditions of wintering and passage areas on the mean passage time of 13 trans-Saharan passerines during their spring migration through the western Mediterranean over the 15 years from 1993 to 2007. 3. We found that most of the species studied have been advancing the timing of their passage in recent years. However, annual variation in the mean date of passage was positively correlated with vegetation growth (measured as the normalized difference vegetation index [NDVI]) both in the Sahel (the region of departure) and in northern Africa (the passage area). Thus, migration dates were delayed in years with high primary productivity in passage and wintering zones. All species seem to respond similarly to NDVI in the Sahel; however, late migrants were less affected by ecological conditions in northern Africa than those migrating earlier, suggesting differences based on species ecology. 4. Mean timing of passage was not related to the North Atlantic Oscillation (NAO), El Niño-Southern Oscillation (ENSO), temperature or NDVI in the species-specific wintering areas (the overwintering region) when analysed in combination with the other covariates. 5. Our findings show that ecological conditions in the winter quarters (specifically the Sahel) and en route are relevant factors influencing trends in the passage dates of trans-Saharan migratory birds on the southern fringe of Europe. Possible long-term consequences for late arriving spring migrants are discussed.
Treatment of Hospital-Acquired Pneumonia

Nosocomial pneumonia is the number one hospital-acquired infection from a mortality perspective, leading to mortality rates ranging from 50 to 70%, and sometimes higher, particularly in mechanically ventilated patients. There are a number of studies that have shown an improved survival rate if patients receive appropriate antibiotic therapy, and the sooner this is delivered, the greater the potential benefit. With this perspective in mind, it is our belief that any patient with hospital-acquired pneumonia (HAP) should receive prompt empiric therapy with a regimen that is likely to be effective. If this is achieved, then patients will have the putative benefit of an enhanced likelihood of survival. The American Thoracic Society (ATS) has recently published guidelines for the empiric therapy of HAP, and their emphasis is to stratify patients into one of three categories, each with a list of likely etiologic pathogens and suggested empiric therapy. Although each institution may have its own unique bacteriology and susceptibility patterns, and controversy about the diagnosis of HAP continues, these guidelines were developed to bring an ordered approach to empiric therapy. With such an approach, a large percentage of patients should be able to receive timely and appropriate antibiotic therapy. This article outlines the rationale for empiric therapy and the principles underlying the recommended regimens.
Patients With IBD are Exposed to High Levels of Ionizing Radiation Through CT Scan Diagnostic Imaging: A Five-year Study

Goals The objective of this study was to assess the total effective dose of ionizing radiation from abdominal diagnostic imaging in patients with inflammatory bowel disease (IBD) over a 5-year period. Background Radiation exposure from diagnostic imaging is becoming increasingly common in IBD patients, in part due the availability of computed tomography (CT). Increased risk of malignancy has been associated with radiation exposure. Study This is a retrospective chart review. A university-based gastroenterology database was searched for patients with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) seen between 2003 and 2008. The cumulative ionizing radiation exposure, expressed in milli-Sieverts (mSv), was then calculated from standard tables and by counting the number of abdominal imaging studies. Results Patients with CD had higher cumulative radiation exposure from diagnostic imaging than patients with UC (14.3±1.45 mSv/5-y period vs. 5.9±0.81 mSv/5-y period, P=0.00003). Three-quarters of the radiation exposure in both CD and UC was from CT scans. Thirty-four percent (127 of 373) of CD patients had CT scans, compared with just 20% (37 of 182) of UC patients. Importantly, 7% of CD patients were exposed to high levels of radiation (>50 mSv/5 y), in contrast to none of the UC patients. Conclusions Patients with IBD, and especially CD patients, undergo frequent diagnostic imaging and thus significant exposure to ionizing radiation. This radiation exposure reaches high levels in 7% of CD patients, mainly from CT scanning. Efforts should be made to minimize the radiation exposure from diagnostic imaging by reducing either the number of studies or radiation dose in modalities with ionizing radiation.
Effect of Date Palm Pollen ( DPP ) on Serum Testosterone Levels in Prepubertal Albino Rats

Date Palm Pollen (DPP) is suggested to increase the concentration of testosterone, follicle stimulating hormone, and luteinizing hormone in rats. We, therefore, planned this study to examine its effect on Serum Testosterone and body weight using prepubertal rats. 4-day old rats were divided into four groups of 12 pups each (Control I, Experimental I, Control II, and Experimental II). Experimental groups I and II were given (Date Pal Pollen (DPP) suspension, in a single oral dose of 120mg/kg daily for 18 and 35 days respectively. At the end of the experiment blood from each animal was drawn by cardiac puncture for serum testosterone levels. Pups were weighed and blood was collected through cardiac puncture on day 22 nd and 39 th post natally. There was no statistically significant difference in the variables of Control and Experimental groups I. Pups who received DPP for 35 days showed statistically significant increase in serum testosterone levels as compared to Control group. Their mean body weight also significantly increased from 89.25±2.00g; in the Control group II to 98.91±6.28g in the Experimental group II. Date Palm Pollen suspension given orally at a dose of 120mg/kg for 35 days resulted in an increase serum testosterone levels with concurrent increase in body weight. Key word: Date Palm pollen, Testosterone, Body weight, Testosterone Replacement Therapy.
Consumers’ acceptance and use of plastic money in Harare, Zimbabwe

The purpose of this paper is to apply unified theory of acceptance and use of technology 2 to determine factors influencing acceptance and use of plastic money in Zimbabwe. ,Using a cross-section of 528 consumers, respondents were randomly intercepted as they walked out of five major supermarkets in Harare, Zimbabwe. Random selection of consumers was done in order to ensure a representative sample. Consumers were asked to complete a structured questionnaire. Structural equation modelling was applied to test research hypotheses. ,Results show that performance expectancy, effort expectancy, hedonic motivation and habit all positively influenced behavioural intention to adopt plastic money. Social influence, facilitating conditions and perceived financial cost all did not have a significant effect on behavioural intention to adopt plastic money. Behavioural intention positively influenced consumers’ use behaviour on plastic money. ,This study is among the pioneers of research in this field in Zimbabwe and other developing countries. Likewise, caution must be taken when researchers try to generalise findings from this study. It is, therefore, recommended that more studies of this nature be conducted in other developing countries in order to have a more solid understanding of consumers’ adoption of plastic money. ,The study advises banks to pay particular attention to performance expectancy, effort expectancy, hedonic motivation and habit when devising strategies to increase the adoption of plastic money. ,Factors that influence the adoption of plastic money are not widely researched under circumstances such as those existing in Zimbabwe. The Zimbabwean financial sector provides a unique environment to conduct studies of this nature.
