THE FRAGILITY OF AESTHETIC KNOWLEDGE: AESTHETIC PSYCHOLOGY AND APPRECIATIVE VIRTUES

It is a commonplace that collectors such as Larry Gagosian and Charles Saatchi have a big influence on the contemporary art-market. Established investors and new collectors alike pay attention to their tastes. Indeed more generally across the arts, dealers, distributors and commercial producers have a massive influence on taste in terms of what they put on, publish or promote within the public domain. Public institutions and galleries are often not far behind and it is no coincidence that publicly funded work often bears all the hallmarks of marketplace trends. This is nothing new. Whilst the forms of commercial support often differ, from the Florence of the Medici through Victorian Britain to the present day, patronage and the marketplace has often dressed up the accoutrements of power and social prestige in the finery of taste.
A New Iterative Estimation Procedure for the Localization of Passive Stationary Objects from Received RF Signals in Indoor Environments

This paper deals with the localization of passive stationary objects from the received radio- frequency (RF) signals in 3-dimensional (3D) indoor environments. Each object located in the 3D indoor environment is modelled by a single point scatterer. The propagation space is equipped with a multiple-input multiple-output (MIMO) wireless communication system. The employed channel model is flexible and allows to have a line-of-sight (LOS) component as well as single- and double- bounce scattering components. Here, we present a new accurate iterative estimation technique for computing the optimal coordinates as well as the number of the main stationary objects (scatterers) in indoor areas. The proposed approach aims at matching the frequency correlation function (FCF) of the transfer function (TF) of the received RF signals to the FCF of the channel model. This iterative procedure is based on numerical optimization techniques to estimate the number and coordinates of the scatterers and the channel parameters by minimizing the Euclidean norm of the fitting error. Numerical results are presented to confirm the accuracy of the proposed estimation procedure by comparing the estimated positions as well as the resulting FCF with the corresponding exact quantities, known from generated RF signals.
Primary Helicobacter pylori Eradication Rates of Lansoprazole, Amoxicillin, and Metronidazole Therapy is Much Higher than Lansoprazole, Amoxicillin and Clarithromycin Therapy in Chiba Prefecture, Japan

Aim: To compare the efficacy of primary Helicobacter pylori eradication therapy between PPI/AC therapy (proton-pump inhibitor; lansoprazole, amoxicillin, and clarithromycin) and PPI/AM therapy (lansoprazole, amoxicillin, and metronidazole). Methods: The subjects were patients with Helicobacter pylori infection who received initial eradication treatment at a family doctor in Katori City, Japan. Infection of Helicobacter pylori was initially evaluated pathologically using gastric mucosal specimens obtained by biopsy through upper endoscopy. Ninety-two patients underwent PPI/AC therapy and 28 patients underwent PPI/AM for primary eradication. Success or failure of eradication was determined by a urea breath test, and the primary eradication rates were compared between the two therapies. Patients who underwent PPI/AC but failed to achieve eradication were recommended to undergo secondary eradication treatment with PPI/AM, and the secondary eradication rate was assessed. Results: In primary eradication therapy, successful eradication rates were 79.3% (73/92) in PPI/AC and 96.4% in PPI/AM, indicating that PPI/AM had a significantly higher eradication success rate (P=0.034). The 19 patients who failed to achieve eradication by PPI/AC underwent secondary eradication by PPI/AM. All 19 cases showed effective eradication (100%). Ultimately, eradication was successful in 99.2% (119/120) patients. Successful eradication rate in the total of primary and secondary PPI/AM treatments was also significantly higher than primary PPI/AC (46/47 vs. 73/92: P=0.007). Neither therapy was associated with any notable side effects. Conclusion: In this regional study, PPI/AM therapy showed a favorable eradication rate, significantly higher than PPI/AC therapy. Thus, PPI/AM therapy is recommended as the primary eradication therapy in the region.
novilhos oriundos do cruzamento rotativo Charolês × Nelore

The carcasses of 800 steers derived from rotational crossbreeding between Charolais and Nellore breeds, slaughtered at two years of age, were evaluated. The evaluated characteristics were the following: conformation, cushion thickness, arm perimeter, Longissimus dorsi area, Longissimus dorsi area divided by 100 kg of cold carcass weight (AOL100). Two models were used for the data analyses: Model 1 included the genetic effects of the breeding system and steer genetic group nested within the breeding system and Model 2 corresponded to Model 1, but the breeding and genetic group were substituted by the covariables corresponding to the percentage of Charolais breed of the individual and its mother and the percentage of heterozygosis of the individual and its mother. From the analysis in Model 1, Charolais steers were superior to the Nelores in all assessed traits. The retained heterosis was significant for conformation (4.2%), cushion thickness (3.2%), arm perimeter (4.2%), Longissimus dorsi area (7.3%) and AOL100 (-6.7%). The individual additive genetic effect of Charolais breed regarded to Nelore was 1.89 points for conformation, 1.37 cm for cushion thickness, 2.55 cm for arm perimeter, 12.70 cm2 for Longissimus dorsi area and 3.13 cm2 for AOL100. The individual heterotic genetic effect (regarded to the straightbred mean) was 3.9% for conformation, 3.8% for cushion thickness, 3.1% for arm perimeter and 9.8% for Longissimus dorsi area. Maternal heterosis is significant only for arm perimeter (1.6%) and AOL100 (-5.4%). The nonadditive genetic effects, represented by epistasis and linkage, do not influence the evaluated characteristics.
Analysis of gender differences in destination decision-making: The case study of Zakynthos Island

The process of tourist decision-making is heavily influenced by a number of external and internal factors, and can be interpreted only by using multidisciplinary theories and techniques in researches. The main goal of tourist s behavior analysis is to understand the motives and reasons of customer decisions during their choice of tourist destination. By getting to know the potential and existing customers, tourism companies can adjust the characteristics of their products. Higher customer satisfaction also means better the financial results. The research was conducted in the summer of 2013, through a structured questionnaire with 28 questions. The sample consists of 100 tourists, who visited the Greek island of Zakynthos as the customers of Rapsody travel, tour operator from Belgrade, Serbia. The aim of this research is to determine the needs and motivation in the process of destination selection of tourists, who visited Zakynthos, and their comparison between genders. Data was processed with the IBM SPSS 19.0. software package for statistical research, through the Chi-Square statistical test. Results of the study showed that there are statistically significant differences only at the question categories of destination decision-making and expressing satisfaction and dissatisfaction.
A Review of the In Vivo Evidence Investigating the Role of Nitrite Exposure from Processed Meat Consumption in the Development of Colorectal Cancer

The World Cancer Research Fund (WCRF) 2007 stated that the consumption of processed meat is a convincing cause of colorectal cancer (CRC), and therefore, the public should avoid it entirely. Sodium nitrite has emerged as a putative candidate responsible for the CRC-inducing effects of processed meats. Sodium nitrite is purported to prevent the growth of Clostridium botulinum and other food-spoiling bacteria, but recent, contradictory peer-reviewed evidence has emerged, leading to media reports questioning the necessity of nitrite addition. To date, eleven preclinical studies have investigated the effect of consuming nitrite/nitrite-containing meat on the development of CRC, but the results do not provide an overall consensus. A sizable number of human clinical studies have investigated the relationship between processed meat consumption and CRC risk with widely varying results. The unique approach of the present literature review was to include analysis that limited the human studies to those involving only nitrite-containing meat. The majority of these studies reported that nitrite-containing processed meat was associated with increased CRC risk. Nitrite consumption can lead to the formation of N-nitroso compounds (NOC), some of which are carcinogenic. Therefore, this focused perspective based on the current body of evidence links the consumption of meat containing nitrites and CRC risk.
Title Behaviour change techniques targeting both diet and physical activity in type 2 diabetes : A systematic review and meta-analysis

Background: Changing diet and physical activity behaviour is one of the cornerstones of type 2 diabetes treatment, but changing behaviour is challenging. The objective of this study was to identify behaviour change techniques (BCTs) and intervention features of dietary and physical activity interventions for patients with type 2 diabetes that are associated with changes in HbA1c and body weight. Methods: We performed a systematic review of papers published between 1975–2015 describing randomised controlled trials (RCTs) that focused exclusively on both diet and physical activity. The constituent BCTs, intervention features and methodological rigour of these interventions were evaluated. Changes in HbA1c and body weight were meta-analysed and examined in relation to use of BCTs. Results: Thirteen RCTs were identified. Meta-analyses revealed reductions in HbA1c at 3, 6, 12 and 24 months of -1. 11 % (12 mmol/mol), -0.67 % (7 mmol/mol), -0.28 % (3 mmol/mol) and -0.26 % (2 mmol/mol) with an overall reduction of -0.53 % (6 mmol/mol [95 % CI -0.74 to -0.32, P < 0.00001]) in intervention groups compared to control groups. Meta-analyses also showed a reduction in body weight of -2.7 kg, -3.64 kg, -3.77 kg and -3.18 kg at 3, 6, 12 and 24 months, overall reduction was -3.73 kg (95 % CI -6.09 to -1.37 kg, P = 0.002). Four of 46 BCTs identified were associated with >0.3 % reduction in HbA1c: ‘instruction on how to perform a behaviour’, ‘behavioural practice/rehearsal’, ‘demonstration of the behaviour’ and ‘action planning’, as were intervention features ‘supervised physical activity’, ‘group sessions’, ‘contact with an exercise physiologist’, ‘contact with an exercise physiologist and a dietitian’, ‘baseline HbA1c >8 %’ and interventions of greater frequency and intensity. Conclusions: Diet and physical activity interventions achieved clinically significant reductions in HbA1c at three and six months, but not at 12 and 24 months. Specific BCTs and intervention features identified may inform more effective structured lifestyle intervention treatment strategies for type 2 diabetes.
Archaeological Demography as a Tool for the Study of Women and Gender in the Past

In the last 20 years, demography has re-emerged as a key research area within archaeology. This research has refined archaeological demographic methods and examined the relationships between demographic, cultural and environmental change. Here, I discuss how the results of the growing corpus of archaeological demographic studies can contribute to gender archaeology, aiding the incorporation of women into narratives of the past. By considering the important role of women in the demographic regimes of small-scale societies, I explain how archaeological demography can provide insights into the behaviour and lives of women, without relying on the often problematic identification of gendered artefacts, activities and/or places. Archaeological demography as a tool for gender archaeology also permits a move away from the female empiricism of simply adding women into archaeological narratives, to provide an alternative framework for the analysis of gender roles and practices. I demonstrate the feasibility and benefits of this approach using an example from the Upper Palaeolithic of southwestern France.
The Impact of the Technological Development Level of Ukrainian Enterprises on the Competitiveness of Their Products

Indicators of the technological development level of enterprises have been proposed in accordance to the type of its output and competitiveness level. We have explained the role of the main factors that influence competitive advantages of the output. The method of the evaluation of the product’s competitiveness level with the use of its manufacture parameters is also presented. The criterion for selecting among possible alternatives such technological process that results in the most competitive type of products has been shown.
Power Adjusting and Bribery Racing: Novel Mining Attacks in the Bitcoin System

Mining attacks allow attackers to gain an unfair share of the mining reward by deviating from the honest mining strategy in the Bitcoin system. Among the most well-known are block withholding (BWH), fork after withholding (FAW), and selfish mining. In this paper, we propose two new strategies: power adjusting and bribery racing, and introduce two novel mining attacks, Power Adjusting Withholding (PAW) and Bribery Selfish Mining (BSM) adopting the new strategies. Both attacks can increase the reward of attackers. Furthermore, we show PAW can avoid the "miner's dilemma" in BWH attacks. BSM introduces a new "venal miner's dilemma", which results in all targets (bribes) willing to help the attacker but getting less reward finally. Quantitative analyses and simulations are conducted to verify the effectiveness of our attacks. We propose some countermeasures to mitigate the new attacks, but a practical and efficient solution remains to be an open problem.

This paper investigates the comparative advantage pattern of the countries in the Middle East and North Africa (MENA) region for the period 2000 and 2010. Revealed Symmetric Comparative Advantage (RSCA) Index, paired sample F-test, t-test, and Spearman’s Rank Correlation are applied, This paper concludes thatthere are significant differences in comparative advantages among countries in the MENA region for 2000 and 2010 period. In addition, the stronger competition occured in resource-poor and labor abundant, resource-rich and labor abundant, and resource-rich and labor importing countries.
Environmental and Biopsychosocial Profiling as a Means for Describing Financial Risk-Taking Behavior

A conceptual model of personal financial risk-taking behavior is described. The approach incorporated environmental and biopsychosocial factors associated with risk-tolerance attitudes and risk-taking financial management behavior. Findings indicated, similar to the method used to describe socioeconomic status, generalized profiling can be a useful tool to help researchers and policy makers improve understanding of the determinants of risk taking. Level of affluence, as described by a person’s environmental profile, appeared to serve as a protection against circumstances that could lead to negative financial behavior. Risk tolerance, as a precipitating risk factor, was an important determinant of financial risk-taking behavior.
Identication in models of sorting with social externalities

This paper develops static and dynamic models of sorting in which location choices depend on the location choices of other agents as well as prices and exogenous location characteristics. In these models, demand slopes and hence preferences are not identiable without further restrictions because of the absence of independent variation of endogenous composition and exogenous location characteristics. Four solutions of this problem are presented and applied to data on neighborhoods in US cities: The rst three use exclusion restrictions, based on either subgroup demand shifters, the spatial structure of externalities, or the dynamics of prices and composition in response to an amenity shock. The fourth tests for multiplicity of equilibria in the dynamics of composition. The empirical results consistently suggest the presence of strong social externalities, that is a dependence of location choices on neighborhood composition.
RISK MANAGEMENT APPROACHES IN DATA MINING By PETER TSYURMASTO A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy RISK MANAGEMENT APPROACHES IN DATA MINING By Peter Tsyurmasto May 2014 Chair: Stan Uryasev Major: Industrial and Systems Engineering This dissertation is dedicated to the development of risk management approach to Support Vector Machine (SVM) for classification. The approach is based on the representation of classical versions of SVM in primal as a minimization of some tail risk measures such as maximal loss, conditional value-at-risk, partial moment, etc. By revisiting the fundamental concepts of structural risk minimization and maximal margin classification we develop a generalized framework, which is shown to contain several classical versions of SVMs such as hard-margin, soft-margin, ν-SVM and extended ν-SVM as its special cases, corresponding to the particular choices of risk functional. Under the assumption that the empirical risk function is positive homogeneous, we derive conditions for which the generalized formulation is equivalent to several structural risk minimization formulations. The considered formulations specify different ways how to express a tradeoff between the empirical risk and regularization. The non-linear Gaussian (RBF) kernel extension is provided for all formulaion. The sufficient conditions for the existence of an optimal solution and unbounded solutions to the associated optimization problems are also given and can be checked before the optimization. Within a presented framework, we propose new classification methods based on value-at-risk and conditional value-at-risk measures, which are stable to data outliers. Computational experiments confirm that the new classifiers have a superior out-of-sample performance on datasets contaminated by outliers, compared to the classical versions of SVM.
Air Quality Deterioration of Urban Areas Caused by Wildfires in a Natural Reservoir Forest of Mexico

Many regions of the world suffer loss of vegetation and reduced air quality due to wildfires. Studies on aerosol emissions by wildfires often discuss the negative effects of atmospheric contaminants from a regional or mesoscale perspective. The occurrence of wildfires reveals that a high percentage takes place close to large urban areas. Very high concentration of pollutants and PM10 particulate matter reach urban zones and millions of inhabitants. These events of high pollutant concentrations are seasonally recurrent. There are many large urban areas in the world that often undergo severe air deterioration due to wildfires smoke. We document the extreme impact of wildfire that occurs in the Protected Area of Flora and Fauna La Primavera located in neighborhood of Guadalajara, a large urban zone in Mexico. The simultaneous emissions of aerosols by 60 wildfires were simulated and compared with observed data. The plume generated by the wildfires reached large areas of the central part of Mexico. The principal characteristics of smog emissions (CO, NO2, and PM10) over the urban area were acceptably reproduced. Observed and modeled CO, PM10, and NO2 data indicated that aerosol plumes generated by the wildfires increased notably the concentrations over the metropolitan zone of Guadalajara.
Word-reading ability as a “hold test” in cognitively normal young adults with history of concussion and repetitive head impact exposure: A CARE Consortium Study

Abstract Objective: Neuropsychological evaluations include hold tests like word-reading ability as estimates of premorbid intellect thought to be resilient to the effects of neurologic insult. We tested the alternative hypothesis that exposure to concussion or repetitive subclinical head impacts throughout early life may stunt acquisition of word-reading skills. Method: Data were obtained from student–athletes within the CARE Consortium that completed the Wechsler Test of Adult Reading (WTAR). Measures of head trauma burden included self-reported concussion history and cumulative years of exposure to collision sports. We evaluated the effects of head trauma, sociodemographic (race, SES), and academic (SAT/ACT scores, learning disorder) variables on WTAR standard score using linear regression. Analyses were repeated in a football-only subsample estimating age of first exposure to football as a predictor. Results: We analyzed data from 6,598 participants (72.2% white, 39.6% female, mean ± SD age = 18.8 ± 1.2 years). Head trauma variables collectively explained 0.1% of the variance in WTAR standard scores, with years of collision sport exposure weakly predicting lower WTAR standard scores (β = .026–.035, very small effect). In contrast, sociodemographic and academic variables collectively explained 20.9–22.5% of WTAR standard score variance, with strongest effects noted for SAT/ACT scores (β = .313–.337, medium effect), LD diagnosis (β = –.115 to –.131, small effect), and SES (β = .101–.108, small effect). Age of first exposure to football did not affect WTAR scores in a football-only sample. Conclusion: Wechsler Test of Adult Reading performance appears unrelated to history of self-reported concussion(s) and/or repetitive subclinical head trauma exposure in current collegiate athletes. Sociodemographic and academic variables should be incorporated in test score interpretations for diverse populations like athletes.
Synthesis, some reactions, cytotoxic evaluation and antioxidant study of novel benzimidazole derivatives

A series of novel benzimidazole derivatives incorporating chalcone (3), pyrazolines(4),(5), (16), oxazoline(6), pyrimidines(7-13),(17) and oxirane(15) derivatives were synthesized and some of their reactions with some electrophiles and /or nucleophiles were studied . Some of the new derivatives were biologically evaluated as antioxidants and the results showed that the presence of the epoxide ring in (15) as well as the pyrimidine thione in (7) are responsible for their reactivity, rather than the presence of the pyrazoline ring system as in (4a) . On the other hand ,some of the synthesized compounds were tested as for their cytotoxic activity and the results were encouraging . All the synthesized compounds were characterized by elemental analysis as well as spectral data such as IR, 1H-NMR and Mass spectra.
