No . 814 OVERCONFIDENCE INCREASES PRODUCTIVITY Yusuke

Recent studies report that productivity increases under tournament reward structures than under piece rate reward structures. We conduct maze-solving experiments under both reward structures and reveal that overconfidence is a significant factor in increasing productivity. Specifically, subjects exhibiting progressively higher degrees of overconfidence solve more mazes. This result shows a positive aspect of overconfidence, which usually has been examined in its negative aspect as an expectation bias. JEL: C9, D03, J33
Evaluation of natural preservatives in combination with acid whey for use in fermented sausage

Natural antioxidant and antimicrobial systems are set to become an important component in food preservation methodology. The effect of alternative natural preservatives (Sinapis alba L.-M, Rosmarinus officinalis L.-R, Juniperus communis L.-J) in combination with acid whey (AW) was investigated after the ripening period (21d) and over a prolonged storage period of sausage. An antioxidant activity of extracts exercise was performed. The antimicrobial, oxidative stability and sensory properties of these natural preservatives were compared to curing-control (C). Significantly lower rancid odor and rancid flavor (1.48) were observed for R and M compared with the C sample. The low level of these attributes evidenced the antioxidant properties of the R sample, which confirmed the lower CD (~0.48-0.48 µmol mg−1) and TBARS values (~0.41-1.02 mg MDA kg−1) during sausage storing and the highest antioxidant activity against ABTS+ radicals (~85.45 %). Incorporation of acid whey with rosemary extract will give the product a threefold effect: high quality (sensory acceptance), healthy benefit (elimination of nitrite and nitrate from meat products) and safety (improved microbiological and oxidative stability).
Multilevel flash cells and their trade-offs

In this paper we compare six different multilevel flash cells, viz., common ground, DINOR, AND, AMG, split gate and NAND. The key conclusions are that the hot electron effect lends itself better than tunneling as the multilevel programming mechanism. The common ground cell is the most suitable for multilevel flash cells. The NAND architecture is the least favorable.
Comparison of Provider Claims Data Versus Medical Records Review for Assessing Provision of Adult Preventive Services

Administrative claims data are often used to assess the delivery of preventive services, yet there are important limitations. This study assessed the use of claims data to measure quality for pay-for-performance and as a preventive services screening tool compared with medical records review. Accuracy and bias in relying on claims data from a provider perspective were investigated, including a comparison of practice types. Claims data consistently underestimated the rate of preventive services, but the type of practice influenced accuracy. Claims data should be used cautiously, if at all, for pay for performance or to trigger reminders for preventive services completion.
A conceptual model for generating and validating in-session clinical judgments

Abstract Objective: Little attention has been paid to the nuanced and complex decisions made in the clinical session context and how these decisions influence therapy effectiveness. Despite decades of research on the dual-processing systems, it remains unclear when and how intuitive and analytical reasoning influence the direction of the clinical session. Method: This paper puts forth a testable conceptual model, guided by an interdisciplinary integration of the literature, that posits that the clinical session context moderates the use of intuitive versus analytical reasoning. Results: A synthesis of studies examining professional best practices in clinical decision-making, empirical evidence from clinical judgment research, and the application of decision science theories indicate that intuitive and analytical reasoning may have profoundly different impacts on clinical practice and outcomes. Conclusions: The proposed model is discussed with respect to its implications for clinical practice and future research.

The flood control compensation benefit of Longyangxia reservoir amounts to 119 million Yuan per year totally.
Personality Factor as a Predictor of Depression Score Among Depressed and CHD Patients.

INTRODUCTION Many risk factors can affect depression and coronary disease, these including physiological and psychological risk factors (such as personality traits). OBJECTIVES Our objectives were to examine whether personality factors (The Five-Factor Model) can predict depression score in the depressed and coronary heart disease (CHD) individuals compared to that of healthy subjects. MATERIALS AND METHODS To achieve the above objectives, 100 depressed (Mean=35.90 years, SD=10.59 years), and 100 CHD (Mean=46.42 years, SD=12.52 years), patients and 100 healthy subjects (Mean = 37.97 years, SD =12.49 years) were selected by convenience sampling method. To compare the three groups of participants, ANOVA test was used. Stepwise Multiple Regression Analysis was used to identify the variables that most closely predict the perceived stress and depression scores. Pearson's Correlation Co-efficient was used to examine the correlation between variables. RESULTS In Neuroticism, the CHD patients had significant highest scores, followed by depressed patients. The healthy group had the least scores. In case of Extraversion, Openness and Agreeableness, healthy participants had significant higher scores followed by the depressed and CHD patients. Only in conscientiousness factor, Depressive and CHD groups had statistically less scores compared to the healthy group. Also, high Neuroticism and Age, and low Extraversion were significant protective factors for depression Scores of CHD patients, while high Neuroticism and low Extraversion function as predictors in the depressed and healthy groups. CONCLUSION The effects of Neuroticism and Extraversion on depression have been reported as inconsistent across previous studies. This study indicates that, older CHD individuals with high Neuroticism and low Extraversion scores are more vulnerable for depression.
Who Needs Chaplain's Visitation in General Hospitals? Assessing Patients with Psychosocial and Religious Needs

Owing to the declining length of patients' hospital stay in recent years, chaplains need evidence-based criteria to decide which patients are likely to have the greatest psychosocial and/or religious-spiritual needs. Therefore, the present pilot study aims at sorting out evidence-based criteria to assess patients with lack of coping resources. A total of 610 patients in the German-speaking part of Switzerland were surveyed with regard to their psychosocial health. The results suggest that lack of vitality (including health condition), lack of support and lack of faith (including spiritual struggle) are valid and reliable criteria for chaplains as internal triggers for pastoral visitation.
Large Networks and Graph Limits

Recently, it became apparent that a large number of the most interesting structures and phenomena of the world can be described by networks. To develop a mathematical theory of very large networks is an important challenge. This book describes one recent approach to this theory, the limit theory of graphs, which has emerged over the last decade. The theory has rich connections with other approaches to the study of large networks, such as "property testing" in computer science and regularity partition in graph theory. It has several applications in extremal graph theory, including the exact formulations and partial answers to very general questions, such as which problems in extremal graph theory are decidable. It also has less obvious connections with other parts of mathematics (classical and non-classical, like probability theory, measure theory, tensor algebras, and semidefinite optimization). This book explains many of these connections, first at an informal level to emphasize the need to apply more advanced mathematical methods, and then gives an exact development of the theory of the algebraic theory of graph homomorphisms and of the analytic theory of graph limits. This is an amazing book: readable, deep, and lively. It sets out this emerging area, makes connections between old classical graph theory and graph limits, and charts the course of the future. --Persi Diaconis, Stanford University This book is a comprehensive study of the active topic of graph limits and an updated account of its present status. It is a beautiful volume written by an outstanding mathematician who is also a great expositor. --Noga Alon, Tel Aviv University, Israel Modern combinatorics is by no means an isolated subject in mathematics, but has many rich and interesting connections to almost every area of mathematics and computer science. The research presented in Lovasz's book exemplifies this phenomenon. This book presents a wonderful opportunity for a student in combinatorics to explore other fields of mathematics, or conversely for experts in other areas of mathematics to become acquainted with some aspects of graph theory. --Terence Tao, University of California, Los Angeles, CA Laszlo Lovasz has written an admirable treatise on the exciting new theory of graph limits and graph homomorphisms, an area of great importance in the study of large networks. It is an authoritative, masterful text that reflects Lovasz's position as the main architect of this rapidly developing theory. The book is a must for combinatorialists, network theorists, and theoretical computer scientists alike. --Bela Bollobas, Cambridge University, UK
Age‐Related Regional Changes in Hydroxyl Radical Stress and Antioxidants in Gerbil Brain

Abstract— The levels of hydroxyl radicals and oxidized GSH have been examined as indices of oxidative stress in young (3 months), middle‐aged (15 months), and old (20–24 months) gerbil brain hippocampus, cortex, and striaturn. The hydroxyl radical stress was estimated by measuring the salicylate hydroxyl radical trapping products 2,5‐and 2,3‐dihydroxybenzoic acid. The stress was significantly higher in all three brain regions in middle‐aged and old gerbils versus young animals (66.0%). Regional comparisons showed that the stress was significantly higher in cortex than in either the hippocampus or striatum of the middle‐aged and old gerbils (32.0%). The ratio of oxidized to total GSH also increased progressively in middle‐aged and old animals in all three brain regions (p < 0.05, 41.1%), further indicating a general age‐related increase in oxidative stress. Parallel to this age‐related increase in oxidative stress, a significant, albeit slight (8%), decrease in neuronal number in hippocampal CA1 region was observed in both the middle‐aged and old animals. Possible differences in antioxidant levels were also examined. Total GSH levels were similar across age groups (variance <12%). However, the regional comparison showed that it was highest in striatum in all age groups. The levels of a‐tocopherol (vitamin E) were significantly higher in the middle‐aged and old animals in all three regions (70.4%). Vitamin E was highest in the hippocampus and the differences between the hippocampus and the cortex and striatum increased with age. Although of a lesser magnitude, significant increases in hippocampal total ascorbic acid level were also noted with age (p < 0.05, 10%). Ascorbic acid was the most regionally specific of the three antioxidants examined, with hippocampus > cortex > striatum for all age groups. The difference in ascorbic acid level between hippocampus and cortex also increased with age (64.4%). The results suggest that the general age‐related, regionally specific increases in oxidative stress stimulate the accumulation of antioxidants. It is interesting that the hippocampus, which is selectively vulnerable to various insults such as ischemia, epilepsy, and insulin‐induced hypoglycemia, exhibits the greatest age‐related increase in vitamin E and ascorbic acid, perhaps reflective of a greater impact of the progressive increase in baseline oxidative stress.
Childhood Sexual Abuse, Attachments in Childhood and Adulthood, and Coercive Sexual Behaviors in Community Males

Associations between self-reported coercive sexual behavior against adult females, childhood sexual abuse (CSA), and child–parent attachment styles, as well as attachment with adult romantic partners, were examined among 176 adult community males. Attachment style with each parent and with romantic partners was also investigated as a potential moderator. Using hierarchical multiple regression analysis, avoidant attachment with mothers in childhood (and also with fathers, in a second model) accounted for a significant amount of the variance in coercive sexual behavior controlling for scores on anxious ambivalent and disorganized/disoriented attachment scales, as predicted. Similarly, in a third model, avoidance attachment in adulthood was a significant predictor of coercive sexual behavior controlling for scores on the anxiety attachment in adulthood scale. These main effects for avoidant and avoidance attachment were not statistically significant when CSA and control variables (other types of childhood adversity, aggression, antisociality, and response bias) were added in each of the models. But the interaction between scales for CSA and avoidance attachment in adulthood was significant, demonstrating incremental validity in a final step, consistent with a hypothesized moderating function for attachment in adulthood. The correlation between CSA and coercive sexual behavior was . 60 for those with the highest third of avoidance attachment scores (i.e., the most insecurely attached on this scale), . 24 for those with scores in the middle range on the scale, and . 01 for those with the lowest third of avoidance attachment scores (i.e., the most securely attached). Implications for study design and theory were discussed.
A fast and efficient ant colony optimization approach for the set covering problem

In this paper, we present an ant colony optimization (ACO) approach to solve the set covering problem. A constraint-oriented solution construction method is proposed. The main difference between it and the existing method is that, while adding a column to the current partial solution, it randomly selects an uncovered row and only considers the columns covering the row, but not all the unselected columns as candidate solution components. This decreases the number of candidate solution components and therefore accelerates the run speed of the algorithm. Moreover, a simple but effective local search procedure, which aims at eliminating redundant columns and replacing some columns with more effective ones, is developed to improve the quality of solutions constructed by ants while keeping their feasibility. The proposed algorithm has been tested on a number of benchmark instances. Computational results indicate that it is capable of producing high quality solutions and performs better than the existing ACO-based algorithms.
Diagnostic potential of serum biomarkers for left ventricular abnormalities in chronic peritoneal dialysis patients.

BACKGROUND N-terminal-pro-brain natriuretic peptide, cardiac troponin T (cTnT) and high sensitivity C-reactive protein (hs-CRP) have been shown to predict mortality and cardiovascular outcomes in end-stage renal disease patients. However, it is not known which biomarkers have the strongest diagnostic potential for left ventricular (LV) abnormalities in chronic peritoneal dialysis (PD) patients, nor whether residual renal function may confound the diagnostic potential of these biomarkers. METHODS Two hundred and thirty chronic PD patients underwent two-dimensional echocardiography to determine LV hypertrophy and ejection fraction and had simultaneous measurement of serum NT-pro-BNP, cTnT and hs-CRP. RESULTS A significant gain in predictive power was observed when NT-pro-BNP or cTnT but not hs-CRP was included in the multivariable logistic regression models for severe LV hypertrophy (defined as LV mass index > or = upper tertile, 247.8 g/m(2)) and systolic dysfunction (defined as ejection fraction < or =45%). Using ROC curve analysis, NT-pro-BNP had the highest diagnostic value for severe LV hypertrophy and systolic dysfunction compared to cTnT and hs-CRP, irrespective of residual renal function. An analysis based on the best cut-off threshold showed that NT-pro-BNP and cTnT had a negative predictive value of 87.1% and 92.6% for severe LV hypertrophy and 95.4% and 93.2% for systolic dysfunction, respectively. Furthermore, the best cut-off threshold of NT-pro-BNP and cTnT for excluding severe LV hypertrophy and systolic dysfunction was nearly 3-fold higher in anuric patients than in patients with residual renal function. CONCLUSIONS Serum NT-pro-BNP appeared most useful in excluding systolic dysfunction in chronic PD patients followed by cTnT. hs-CRP was not useful in this regard. Residual renal function confounded the interpretation of these biomarkers and reduced their predictive power. A nearly 30% higher cut-off threshold of NT-pro-BNP and cTnT had to be applied in anuric PD patients.
Total and Labile Soil Organic Matter in Organic and Conventional Farming Systems

Even though organic management practices are intended to enhance soil performance by altering the quantity or quality of soil organic matter (SOM), there is no consensus on how to measure or manage SOM status. We investigated the veracity of common perceptions about SOM quantity in organically and conventionally managed soils by evaluating the relative responsiveness to organic management of particulate organic matter (POM) and the Illinois Soil N Test (IL-N), which has been proposed as a direct measure of labile N. Soil samples were obtained from nine farming systems trials in the USA. Soil organic C (SOC), total N (TN), POM-C, POM-N, and IL-N were compared among manure 1 legume-based organic, legume-based organic, and conventional farming systems. The organic systems had higher SOC and TN concentrations than conventional systems whether or not manure was applied. The POM-C, POM-N, and IL-N concentrations did not differ between manure 1 legumeand legume-based organic systems. The amount of N recovered in POM and IL-N was similar. Organic management enriched soil POMC and -N by 30 to 40% relative to the conventional control and this level of enrichment was two to four times greater than that in any other fraction. The IL-N fraction was not a good measure of labile N as it was less enriched than POM and included recalcitrant components. This is evidenced by the strong correlation between IL-N and SOC, TN, climate and textural characteristics. Particulate organic matter provided clearer evidence of SOM and labile N accrual under organic management. Direct links between POM status and soil N supply and physical condition are being pursued to help farmers manage biologically based fertility.
Identification of the transcription factor HOXB4 as a novel target of miR‐23a

The transcription factor HOXB4 not only plays a role during nephrogenesis, but displays also oncogenic characteristics in different malignant neoplasms. An in‐silico analysis revealed HOXB4 as a new target of microRNA‐23a (miR‐23a). Nephroblastomas are malignant embryonal renal neoplasms of childhood resembling developing kidney morphologically and genetically. In our study we verified HOXB4 as a target of miR‐23a and furthermore examined the expression of HOXB4 and miR‐23a in nephroblastomas. We investigated binding of miR‐23a to the 3'UTR of HOXB4 by a luciferase assay. Effects on protein levels of HOXB4 were analysed in Western blot experiments. Expression of HOXB4 in nephroblastomas was assessed by quantitative REALtime PCR (qRT PCR) and immunohistochemistry. The luciferase reporter assay showed a statistically significant downregulation of activity by 72,5% demonstrating direct binding of miR‐23a to the 3'UTR of HOXB4. In addition, miR‐23a reduced the protein expression of HOXB4 statistically significantly by 65.1%. All 21 nephroblastomas investigated had statistically significantly decreased expression levels of miR‐23a. A high level of HOXB4 mRNA was found in five out of 33 nephroblastomas including mixed, blastema‐type and stroma‐type tumors. Protein expression of HOXB4 was stronger in 15 out of 27 nephroblastomas of all subtypes in a semiquantitative comparison to normal kidney parenchyma. Our study demonstrates for the first time the regulation of HOXB4 by miR‐23a. In comparison to mature kidney, nephroblastomas had low levels of miR‐23a, and in a majority of them a stronger protein expression in comparison to mature kidney was found. © 2013 Wiley Periodicals, Inc.
Hairy cell leukemia: An unusual lymphoproliferative disease. A study of 24 patients

A laboratory and clinical evaluation of 24 patients with hairy cell leukemia was carried out over a 23‐month period. Most patients had splenomegaly without adenopathy or pancyotpenia. Nine of the patients had undergone splenectomy prior to referral; their median WBC count was 6600/mm3. The median WBC count for the 14 patients who had no prior therapy was 3550/mm3, and their median platelet count was 80,500/mm3. Spleen weights ranged from 618 to 3780 g; there appeared to be no relationship between the size of the spleen and the response in the blood counts after splenectomy. Four patients in whom the majority of the WBC were hairy cells underwent splenectomy, which produced no real change in their WBC count; however, there was improvement in the platelet count in three. In contrast, the presence of leukopenia with a low percentage of hairy cells predicted a beneficial response to splenectomy. The study of surface immunoglobulins (SIg) in 16 patients demonstrated that resynthesis had occurred in each case. Phagocytosis of zymosan was studied in 15 patients; in 8 of these, 25% or more of the hairy cells were capable of phagocytosis; in 6 others, 0–9%; and in one, 13%. The resynthesis of SIg is a feature usually associated with B‐lymphocytes, but the phagocytosis of zymosan is not. Thus, the existence of either a spectrum of functional capabilities of hairy cells or several distinct subtypes is suggested by these data. Platelet aggregation with epinephrine was abnormal in 7 of 14 patients studied but there were no clinically significant bleeding problems. A chromosome abnormality was present in 2 of the 19 patients from whom adequate samples were obtained; the abnormality probably involved chromosome 12 in both patients as well as absent Y and was associated with a rapidly progressive clinical course. The presence of a predominant number of hairy cells with a normal or increased peripheral blood WBC count or of a chromosomal abnormality suggests that splenectomy might not be beneficial as the initial therapy and that chemotherapy should be considered.
