Posting photos of luxury cuisine online: an exploratory study

Purpose The purpose of this paper is to identify the motives for posting or sharing food photos using social media, focussed within the context of fine dining (FD) restaurants. Design/methodology/approach Ethnographic fieldwork was conducted in France by combining analysis of qualitative diary research and transcripts of focus group discussions. Findings The motivation to take food images can be broadly categorised according to experiential (hedonism, altruism and passion collecting) and symbolic (social status, uniqueness, self-esteem and self-presentation) benefits. Research limitations/implications This research is limited by its relatively small sample size and the inability to consider the direct influences of demographic variables and attitudes to FD and social media. Moreover, the cultural context of the study needs to be considered as the study took place in France. Practical implications User-generated images are increasingly an integral aspect of the holistic dining experience. Luxury restaurants need to leverage the opportunities of user-generated content. The FD experience needs to be visually captured and expressed. This can include both tangible and intangible attributes. Originality/value Although the literature has provided a comprehensive overview of social media behaviour, the efficacy of a gastronomic perspective is limited. To the authors’ knowledge, this is the first study to investigate consumer-generated postings of images of food within the luxury restaurant classification.
Therapeutic plasma exchange and intravenous immunoglobulin as primary therapy for D alloimmunization in pregnancy precludes the need for intrauterine transfusion

Maternal D alloimmunization detected in early gestation requires aggressive intervention to prevent severe fetal anemia. An intrauterine transfusion (IUT) is indicated to prevent fetal death once severe fetal anemia has been detected, but is not without risk. Protocols combining therapeutic plasma exchange (TPE) and intravenous immunoglobulin (IVIG) have been described, but they usually bridge to IUT.
Comprehensive Outcome and Cost Analysis of Free Tissue Transfer for Breast Reconstruction: An Experience with 1303 Flaps

Background: Free tissue transfer is standard for postoncologic reconstruction, yet it entails a lengthy operation and significant recovery. The authors present their longitudinal experience of free tissue breast reconstructions with an emphasis on predictors of major surgical and medical complications. Methods: The authors reviewed their prospectively maintained free flap database and identified oncologic breast reconstruction patients from 2005 to 2011. Factors associated with surgical and medical complications were identified using univariate analyses and logistic regression to determine predictors of complications. Results: Complications included major immediate surgical complications [n = 34 (4.0 percent)], major delayed surgical complications [n = 54 (6.4 percent)], minor surgical complications [n = 404 (47.6 percent)], and medical complications [n = 50 (5.9 percent)]. Obesity (p = 0.034), smoking (p = 0.06), flap type (p = 0.005), and recipient vessels (p < 0.001) were associated with immediate complications. Similarly, delayed surgical complications were associated with obesity (p < 0.001), chronic obstructive pulmonary disease (p < 0.001), hypertension (p < 0.001), and prior radiation therapy (p = 0.06). Regression analysis demonstrated that flap choice (p = 0.024) was independently associated with major immediate complications, and patient comorbidities such as chronic obstructive pulmonary disease (p = 0.001) and obesity (p < 0.0001) were associated with delayed complications. Patients who developed an immediate surgical complication experienced longer hospital stays (p < 0.0001), higher operating costs (p < 0.001), and greater hospital costs (p < 0.001). Conclusions: Early major complications are related to flap selection, whereas late major complications are associated with patient comorbidities. Overall, major surgical and medical complications are associated with increased hospital length of stay and greater cost in autologous breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.
New Selective Growth Inhibitors of Sphaerotilus natans, Anslimins A and B

Selective growth inhibitors of Sphaerotilus natans were detected in the culture broths of several strains of Streptomyces. Anslimins A and B were isolated from the culture broth of Streptomyces oganonensis by adsorption on resinous adsorbent followed by elution with 50% aqueous acetone. The A and B components were then separated by cellulose powder chromatography. Physicochemical parameters of anslimins A and B revealed that these compounds are new peptide-containing structures. Anslimins A and B inhibited growth of S. natans at 0.78 and 0.39 μg/ml, respectively, but showed no activity against any of the other test microorganisms at 100 to 200 mg/ml. The anslimins had no harmful effect on guppies at a concentration of 100 mg/liter.
Inappropriate ceftriaxone use in the emergency department of a tertiary hospital in Melbourne, Australia

reflecting the sorts of pre-drawn or spare drugs that were commonly carried, namely 5 mL syringes for muscle relaxants, 10 mL syringes for saline flushes and analgesia, 20 mL syringes for metaraminol infusions and ketamine dilutions and 60 mL syringes for propofol and common inotrope infusions. These pads with elastic loops were then positioned on the loop-side pads on the ventilator bag. Syringes are stored with red bungs in place to prevent leaks due to cabin pressure changes (Fig. 1). A similar process was undertaken with our Schiller Argus monitor pouches (Schiller AG, Baar, Switzerland), to be used in situations where the ventilator was not required. The system was implemented rapidly, and at minimal cost, and has been positively received by the retrieval teams. The concept is not limited to the equipment used by our retrieval service, and might be worth considering by our colleagues in other retrieval services.
The Individual and Combined Effects of Fusaric Acid and T-2 Toxin in Broilers and Turkeys

Two experiments were conducted to evaluate the individual and combined effects of fusaric acid (FA) and T-2 toxin (T-2) in broiler chicks and turkey poults. In each experiment, 80 day-old birds were allotted randomly to a 2×2 factorial arrangement with treatments of 0 and 250 mg FA/kg feed and 0 and 4 mg T-2/kg feed. Diets were fed to 4 pen replicates of 5 birds each for 21 days. Feed intake and body weight gain of poults were reduced (p 0.05) on performance of broilers. Poults fed FA and the FA\T-2 combination diets had increased (p<0.05) heart weights, whereas chicks fed FA and the FA\T-2 combination diets had increased (p<0.05) kidney weights. Poults fed the combination FA\T-2 diet had higher (p<0.05) serum AST values compared to all other treatments. Poults fed the T-2 and FA\T-2 combination diets had increased (p<0.05) serum Na but reduced (p<0.05) serum Mg. Uric acid concentrations were higher (p<0.05) in chicks fed the FA and FA\T-2 combination diets. Oral lesions were present in chicks (68%) and poults (100%) fed T-2 with or without FA. Data indicate no toxic synergy when FA and T-2 were fed simultaneously to broilers and turkeys at these dietary concentrations.
Diagnosing Faults in Power Transformers With Autoassociative Neural Networks and Mean Shift

This paper presents a new approach to incipient fault diagnosis in power transformers, based on the results of dissolved gas analysis. A set of autoassociative neural networks or autoencoders is trained, so that each becomes tuned with a particular fault mode or no fault condition. The scarce data available forms clusters that are densified using an Information Theoretic Mean Shift algorithm, allowing all real data to be used in the validation process. Then, a parallel model is built where the autoencoders compete with one another when a new input vector is entered and the closest recognition is taken as the diagnosis sought. A remarkable accuracy of 100% is achieved with this architecture, in a validation data set using all real information available.
Understanding Uncertainty in safety-critical industries

Increasing attention in the project management literature is being paid to the theme of uncertainty: its origins and how it impacts projects (see for instance Atkinson, Crawford & Ward, 2006 and Perminova, Gustafsson & Wikstrom, 2008). The purpose of this exploratory study was to investigate the determinants and impacts of project uncertainty in the context of safety-critical industries in the United Kingdom. Seven current projects across two such safety-critical industries, civil nuclear and aerospace, were studied by means of in-depth interviews with senior project managers. The authors posit a framework, incorporating four determinants of uncertainty that are prevalent in large-scale projects in these sectors. The framework comprises project content, context, organisational capability and culture. We then explain how these four determinants of uncertainty may impact on the delivery of project outcomes. Future work is now required to test the validity of these preliminary conclusions against a larger sample size, and to compare the determinants and impacts of uncertainty on safety-critical projects in the context of locations other than the UK.
Divalent cation transport systems of Rhodopseudomonas capsulata

Separate divalent cation transport systems for energy-dependent uptake of Mg2+ and Mn2+ were found both with aerobically and heterotrophically grown and with photosynthetically grown cells of Rhodopseudomonas capsulata. The maximum rate of Mg2+ uptake differed between photosynthetic and aerobic cells, while the Km for the Mg2+ transport system was constant. Photosynthetic midlog-phase cells exhibited Km's for uptake of about 55 micrometer Mg2+ and 0.5 micrometer Mn2+. The Vmax's also differed between the two systems: 0.6 to 1.8 mumol/min per g (dry weight) of cells for Mg2+, but only 0.020 mumol/min per g for Mn2+, making the distinction between a "macro-requirement" system and a system functioning at trace nutrient levels. Calcium was not normally taken up by intact cells of R. capsulata. However, chromatophore membranes isolated from photosynthetic cells took up Ca2+ by an energy-dependent process.
Vitamin D Status and Concomitant Autoimmunity in Celiac Disease

Goals: To determine whether patients with celiac disease (CD) and low vitamin D levels also have a higher prevalence of other autoimmune diseases (AD) as compared with patients with normal vitamin D levels. Background: Patients with CD carry a higher risk of other autoimmune disorders. Because of its immunoregulatory properties, vitamin D deficiency has been proposed in the pathogenesis of a variety of AD. Whether low vitamin D levels in patients with CD can predict concomitant AD is unknown. Study: A retrospective cross-sectional study of 530 adult patients with CD and a 25-hydroxyvitamin D level on record at Columbia University Medical Center. Results: One hundred thirty-three patients (25%) had vitamin D deficiency. The prevalence of AD was similar among those with normal vitamin D levels (11%), insufficiency (9%), and deficiency (12%, P=0.66). On multivariate analysis, adjusting for age of CD diagnosis and sex, vitamin D deficiency was not associated with AD (odds ratio, 1.35; 95% confidence interval, 0.62-2.95). The risk of psoriasis was higher in patients with vitamin D deficiency (7% vs. 3%, P=0.04). Vitamin D deficiency was more common in those who presented with anemia (39%) than in those who did not (23% P=0.002). Conclusions: Vitamin D deficiency in CD is common but does not predict AD. The risk of psoriasis is increased in vitamin D-deficient CD patients. Assessment of vitamin D seems to be a high-yield practice, especially in those CD patients who present with anemia.
Nano precision on-machine profiling of curved diamond cutting tools using a white-light interferometer

A non-contact on-machine measurement method is proposed for evaluating the profile accuracy of curved diamond cutting tools. The system is based on a compact white-light interferometer which is mounted on a three-axis numerical-controlled ultraprecision machine tool. An algorithm was developed to automatically identify the cutting edge location using the three-dimensional measurement data. Then the cross-sectional profile of the tool is extracted and the distribution of tool profile error is obtained. To measure tools with wide window angles and large curvatures, a data-stitching technique has been proposed for connecting the individually measured profiles from various orientations of the tool.
Coordination of altered DNA repair and damage pathways in arsenite-exposed keratinocytes.

Human exposure to arsenic, a ubiquitous and toxic environmental pollutant, is associated with an increased incidence of skin cancer. However, the mechanism(s) associated with AsIII-mediated toxicity and carcinogenesis at low levels of exposure remains elusive. Aberrations in cell proliferation, oxidative damage, and DNA-repair fidelity have been implicated in sodium arsenite (AsIII)-mediated carcinogenicity and toxicity, but these events have been examined in isolation in the majority of biological models of arsenic exposure. We hypothesized that the simultaneous interaction of these effects may be important in arsenic-mediated neoplasia in the skin. To evaluate this, normal human epidermal keratinocytes (NHEK) were exposed to nontoxic doses (0.005-5 micro M) of AsIII and monitored for several physiological endpoints at the times when cells were harvested for gene expression measurements (1-24 h). Two-fluor cDNA microarray analyses indicated that AsIII treatment decreased the expression of genes associated with DNA repair (e.g., p53 and Damage-specific DNA-binding protein 2) and increased the expression of genes indicative of the cellular response to oxidative stress (e.g., Superoxide dismutase 1, NAD(P)H quinone oxidoreductase, and Serine/threonine kinase 25). AsIII also modulated the expression of certain transcripts associated with increased cell proliferation (e.g., Cyclin G1, Protein kinase C delta), oncogenes, and genes associated with cellular transformation (e.g., Gro-1 and V-yes). These observations correlated with measurements of cell proliferation and mitotic measurements as AsIII treatment resulted in a dose-dependent increase in cellular mitoses at 24 h and an increase in cell proliferation at 48 h of exposure. Data in this manuscript demonstrates that AsIII exposure simultaneously modulates DNA repair, cell proliferation, and redox-related gene expression in nontransformed, normal NHEK. It is anticipated that data in this report will serve as a foundation for furthering our knowledge of AsIII-regulated gene expression in skin and other tissues and contribute to a better understanding of arsenic toxicity and carcinogenesis.
Public sector efficiency in Europe: Long-run trends, recent developments and determinants

This paper investigates the efficiency of the public sector in a sense of public performance and expenditures. For 23 European countries and for the period between 1995 and 2015 we construct a measure of public sector performance that consist of nine distinct indices for each area of public policy, such as administration, health education, economic performance, security and infrastructure. We use several efficiency techniques (FDH, order-m) and investigate input- and output-oriented efficiency of the public sector. We find that countries with small public sectors tend to be more efficient no matter which efficiency techniques we use. Because of the relatively long time span of our data, our study contributes to the literature by analyzing the effect of the financial crisis on the efficiency of the public sector in European countries. We show that after the crisis, the public sector efficiency increased especially in countries with small public sectors, while it stayed constant or worsened in countries with big public sectors. Finally, we analyze in more depth the impact of fiscal decentralization and fiscal rules on the public sector efficiency. We conclude that while decentralization is fostering efficiency, fiscal rules do not have any effect. Moreover, fiscal rules combined with decentralization may harm efficiency, consistently with the ratchet effect.
Exploring the Role of Analogico-Deductive Reasoning in the Balance-Beam Task

Piaget’s classic experiments enabled, among many other things, identification of the types of reasoning children use in different developmental stages. His work identified both hypothetico-deductive and analogical reasoning as strong indicators of normal development. Although examples of each can be seen early on, consistent application and control of these types of reasoning emerges somewhere between Stages III and IV. Given their importance in the developmental process, it can only help the study of cognitive development to have a deeper understanding of how these types of reasoning are carried out. We focus in this paper on ways in which they interact (we call this ADR, for analogico-deductive reasoning); specifically on the interaction of generation, development, and testing of hypotheses. We present a model and show how it can explain the reasoning processes of a Stage-III subject working on Inhelder and Piaget’s (1958) seminal balance-beam task. Analogy and Analogico-Deductive
The Abolition of Immigration Restrictions and the Performance of Firms and Workers: Evidence from Switzerland

We study a reform that granted European cross-border workers free access to the Swiss labor market and had a stronger effect on regions close to the border. The greater availability of cross-border workers increased foreign employment substantially. Although many cross-border workers were highly educated, wages of highly educated natives increased. The reason is a simultaneous increase in labor demand: the reform increased the size, productivity, and innovation performance of skill-intensive incumbent firms and attracted new firms, creating opportunities for natives to pursue managerial jobs. These effects are mainly driven by firms that reported skill shortages before the reform. (JEL J15, J23, J24, J31, J61, K37)
Intrapericardial Procaine Affects Volume Expansion-Induced Fos Immunoreactivity in Unanesthetized Rats

Acute volume expansion is associated with a specific pattern of Fos expression and the goal of the present study was to evaluate the contribution of cardiac receptors to this response. Adult male rats were instrumented with pericardial catheters introduced at the level of the thymus. Rats were also catheterized for measuring blood pressure, heart rate, central venous pressure, and intravenous infusion. Each rat received a 200-microl intrapericardial (i.p.c) injection of 2% procaine or 0.9% NaCl. Rats were then volume expanded with isotonic saline (10% body weight in 10 min) or given a control infusion (0.01 ml/min for 10 min). Ninety minutes after the start of the infusion, the rats were anesthetized and perfused transcardially. Their brains were sectioned and processed for Fos, dopamine-beta-hydroxylase, and oxytocin immunocytochemistry. Volume expansion plus i.p.c. saline produced a significant increase in Fos expression in the nucleus of the solitary tract, the ventrolateral medulla, the area postrema, the locus coeruleus, the paraventricular nucleus of the hypothalamus, the perinuclear zone of the supraoptic nucleus, and oxytocin neurons in the supraoptic nucleus. The i.p.c. procaine significantly blocked Fos expression produced by the volume expansion in the all of the regions examined except for the area postrema and the SON oxytocin neurons.
A Comparative Analysis of Traditional Software Engineering and Agile Software Development

Over the last decade (or two) the pendulum of developer mindshare has swung decidedly towards agile software development from a more traditional engineering approach to software development. To ascertain the essential differences and any possible incompatibilities between these two software development paradigms this research investigates a number of traditional and agile methodologies, methods, and techniques. The essential differences between traditional software engineering and agile software development are found not to be (as one may first suspect from a cursory consideration) related to iteration length or project management, but rather more related to other attributes like the variety of models employed, the purpose of the models, and the approach to modeling. In the end though the two approaches are not seen to be incompatible, leading to the future possibility of an Agile Software Engineering (ASE).
Organizational innovation across the technological innovation process: The moderating influence of hybrid change agents

A rapidly increasing number of studies provide evidence of the positive impact of organizational innovation, that is, the development and implementation of new organizational practices, processes, and structures, on firms' propensity to develop new and improve existing products and processes. When investigating the initiators of organizational innovation, to date, research has primarily focused on internal and external change agents at upper echelons, neglecting the role of hybrid change agents at lower echelons. We argue that hybrid change agents, because of their unique ability to integrate external and internal knowledge, are particularly important for organizational innovation and may positively influence the technological innovation process. We examine how apprentices in the Swiss Vocational Education and Training (VET) system are key to integrating external knowledge (through school-based education) with internal knowledge (through on-the-job training) and moderating the influence of organizational innovation on technological innovation. Drawing on a sample of 1,240 firms from a representative Swiss Innovation Survey, we show that apprentices leverage the positive effects of innovations in a firm's business processes and organization of work on incremental innovations. We contribute to the literature on complementarities between organizational and technological innovation by highlighting the role of hybrid change agents at the lower echelons and by revealing how different types of organizational innovation affect technological innovation across the innovation process. We also contribute to the literature on VET systems by revealing the significant role of apprentices on firms' technological innovation activities.
Analysis of dichotomous response models for low-dose carcinogenic risk estimation

Several dichotomous-response models of carcinogenesis are discussed and their implications for low-dose risk estimation are examined. In addition, a pharmacokinetic model incorporating non-linear kinetics is studied and the results are investigated with respect to multiple-pollutant exposures. None of these models appears to suggest the existence of "thresholds". The analysis of both linear and nonlinear models indicates that if background concentrations are present, then under almost all models discussed, the marginal response associated with the new carcinogen increases more linearly with dose. The results of the study are then examined with respect to dispersal of carcinogenic pollutants as a means of reducing environmental hazards to a given population. It was then concluded that dispersal may not reduce the overall risk if linear or near-linear dose-response relationships are assumed. A conceptual experimental design is also presented to investigate a general relationship between dispersal and total population incidence.
