Emotion-specific modulation of early visual perception

Exposure to fearful facial expressions enhances vision at low spatial-frequencies and impairs vision at high spatial-frequencies. This perceptual trade-off is thought to be a consequence of a fear-related activation of the magnocellular visual pathway to the amygdala. In this study we examined the generality of the effect of emotion on low-level visual perception by assessing participants' orientation sensitivity to low and high spatial-frequency targets following exposure to disgust, fear, and neutral facial expressions. The results revealed that exposure to fear and disgust expressions have opposing effects on early vision: fearful expressions enhanced low spatial-frequency vision and impaired high spatial-frequency vision, while disgust expressions, like neutral expressions, impaired low spatial-frequency vision and enhanced high spatial-frequency vision. Thus we show the effect of exposure to fear on visual perception is not a general emotional effect, but rather one that may that depend on amygdala activation, or one that may be specific to fear.
Toward an articulation of interaction esthetics

Even though the emerging field of user experience generally acknowledges the importance of esthetic qualities in interactive products and services, there is a lack of approaches recognizing the fundamentally temporal nature of interaction esthetics. By means of interaction criticism, I introduce four concepts that begin to characterize the esthetic qualities of interaction. Pliability refers to the sense of malleability and tightly coupled interaction that makes the use of an interactive visualization captivating. Rhythm is an important characteristic of certain types of interaction, from the sub-second pacing of musical interaction to the hour-scale ebb and flow of peripheral emotional communication. Dramaturgical structure is not only a feature of online role-playing games, but plays an important role in several design genres from the most mundane to the more intellectually sophisticated. Fluency is a way to articulate the gracefulness with which we are able to handle multiple demands for our attention and action in augmented spaces.
A Macroeconomic Hedge Portfolios and the Cross-Section of Stock Returns

We use a stock’s covariation with unexpected macroeconomic news to derive a stock’s hedging ability of unexpected changes in an investor’s marginal utility. We form a macroeconomic hedge portfolio by going long in stocks with bad hedging abilities and short in stocks with good hedging abilities. This hedge portfolio earns a positive premium over time and a similar premium when used as a risk factor in an asset pricing model. When the macroeconomic hedge portfolio is present in an asset pricing model, the factors HML and SMB lose most of their power to explain the cross-section of expected returns.
Pediatric Seizure prediction from EEG signals based on unsupervised learning techniques using various distance measures

Epilepsy or recurrent seizures is one of the most common non communicable neurological disorder that is prevalent in today's world population are sudden outburst of excess electrical activity of the neurons. Epilepsy can be detected from Electroencephalogram (EEG) as EEG captures and presents the electrical activity of the brain. Non-invasive EEG or scalp EEG is generally used where electrodes are placed on the scalp in order to record the brain activity. In this work a unsupervised machine learning technique is explored which is used to cluster and extract features from EEG recordings (noninvasive) to detect seizures. A patient specific approach is adopted on an open dataset (Physionet database) from where 51 seizure and 51 non seizure recordings of pediatric subjects (age ranging from lyrs to 12yrs) are considered for the related work. Unsupervised algorithm used here is the k-means algorithm to cluster the recordings into two distinct clusters of seizure and non-seizure data. When the performance of the algorithm was tested the algorithm worked with 91.43% accuracy from nearly 18, 00, 000 data taken from various subject. In future scope of work the accuracy of the method can be enhanced using appropriate features for distinctly identifying different intractable seizures according to their characteristics that are prevalent among pediatric patients.

Quality of cancer family history and referral for genetic counseling and testing among oncology practices: a pilot test of quality measures as part of the American Society of Clinical Oncology Quality Oncology Practice Initiative.

PURPOSE Family history of cancer (CFH) is important for identifying individuals to receive genetic counseling/testing (GC/GT). Prior studies have demonstrated low rates of family history documentation and referral for GC/GT. METHODS CFH quality and GC/GT practices for patients with breast (BC) or colon cancer (CRC) were assessed in 271 practices participating in the American Society of Clinical Oncology Quality Oncology Practice Initiative in fall 2011. RESULTS A total of 212 practices completed measures regarding CFH and GC/GT practices for 10,466 patients; 77.4% of all medical records reviewed documented presence or absence of CFH in first-degree relatives, and 61.5% of medical records documented presence or absence of CFH in second-degree relatives, with significantly higher documentation for patients with BC compared with CRC. Age at diagnosis was documented for all relatives with cancer in 30.7% of medical records (BC, 45.2%; CRC, 35.4%; P ≤ .001). Referall for GC/GT occurred in 22.1% of all patients with BC or CRC. Of patients with increased risk for hereditary cancer, 52.2% of patients with BC and 26.4% of those with CRC were referred for GC/GT. When genetic testing was performed, consent was documented 77.7% of the time, and discussion of results was documented 78.8% of the time. CONCLUSION We identified low rates of complete CFH documentation and low rates of referral for those with BC or CRC meeting guidelines for referral among US oncologists. Documentation and referral were greater for patients with BC compared with CRC. Education and support regarding the importance of accurate CFH and the benefits of proactive high-risk patient management are clearly needed.
Image denoising based on scale-space mixture modeling of wavelet coefficients

In this paper, we propose a novel hierarchical statistical model for image wavelet coefficients. A simple classification scheme is used to construct a model that captures interscale and intrascale dependencies of wavelet coefficients. Applications to image denoising are presented. We develop a simple algorithm that outperforms other wavelet denoising schemes that exploit first order statistics, or inter- or intra-scale dependencies alone.
Ethyl Pyruvate Improves Survival and Ameliorates Distant Organ Injury in Rats With Severe Acute Pancreatitis

Objective To evaluate the effect of ethyl pyruvate (EP) in improving the survival and ameliorating distant organ damage and to investigate the role of high-mobility group box (HMGB) 1 in rats with established severe acute pancreatitis (SAP). Methods Severe acute pancreatitis was induced by retrograde infusion of sodium taurodeoxycholate (5%, 1 mL/kg) into the biliopancreatic ducts in male Wistar rats. The rats were infused intravenously with EP of 40 mg/kg, 4 mg/kg, and 0.4 mg/kg initiating 12 hours, and EP of 40 mg/kg was administered beginning 2 hours before surgery (−2 hours) and 12, 24, and 36 hours after induction of SAP; then, the mortality was recorded. Serum tumor necrosis factor &agr;, interleukin (IL) 6, and IL-1&bgr; were measured using enzyme-linked immunosorbent assay. High-mobility group box 1 levels were measured using Western immunoblotting analysis. Results Serum HMGB1 levels were increased dramatically after 12 hours, remained at high levels for 72 hours, and were significantly higher in rats with SAP than in those with mild and moderate pancreatitis (P < 0.01). Treatment with EP (40 mg/kg) conferred protection from lethality of SAP (EP survival [63%] vs vehicle survival [6.3%]; P < 0.001). No survival advantage occurred when treatment was initiated 36 hours after surgery, but administration beginning 2 hours before operation (−2 hours) and 12 and 24 hours after induction of SAP significantly increased survival. Ethyl pyruvate treatment significantly decreased serum HMGB1, tumor necrosis factor &agr;, IL-1&bgr;, and IL-6 levels and ameliorated extrapancreatic organ dysfunction in rats with SAP. Conclusions Ethyl pyruvate improves survival and ameliorates distant organ injury of SAP. These beneficial effects of EP are because of the modulation of HMGB1 and other inflammatory cytokine responses.Abbreviations: SAP - severe acute pancreatitis, EP - ethyl pyruvate, HMGB - high-mobility group box, TNF - tumor necrosis factor, IL - interleukin
AC 2007-1529: INCREASING RETENTION OF WOMEN ENGINEERING STUDENTS

This paper reports the results of a study carried out over several years to determine the factors predicting success for women engineering students at Santa Clara University. We examined psychosocial factors, such as commitment to engineering and confidence in engineering abilities, as well as the effect of a specific intervention on the retention rate of young women engineering students. Studies have shown that among students with adequate aptitude for STEM (Science, Technology, Engineering, and Mathematics), girls drop out more often than boys. Several programs have been developed to encourage girls to persevere in their interests in STEM fields. In the summer of 1999, SCU hosted a National Science Foundation workshop [1] gathering directors of such programs to share their experience and insights. Forty-four people representing over 30 STEM programs for girls in the United States and Canada met to share the successes and challenges they had witnessed in their programs. We applied the experience gained in the workshop discussions in developing a questionnaire to assess psychosocial factors that appeared to be related to the retention of women engineering undergraduates. Exploratory factor analyses and reliability analyses confirmed that our newly-developed measure reliably assessed nine factors that had been suggested as important for retention: commitment, confidence, the value of engineering, computer interest, beliefs that anyone can succeed in engineering, family support, social perceptions, and perceptions of bias in the field of engineering. Equipped with this new measure, we then designed an intervention aimed at enhancing the students’ view of themselves as “techies. ” Each young woman received a handheld computer, and agreed to complete surveys regarding her use of the computer and to meet with the other students to share experiences, evaluate the computer’s capabilities, and imagine ways it could be improved. We tracked the graduation rates and degrees earned by these students and compared them with women engineering majors who came before and after this cohort. Four-year and six-year graduation rates were higher for the intervention cohort (54% and 69%, respectively) than for comparison cohorts (48% and 57%, respectively)
Public and Private Information: Firm Disclosure, SEC Letters, and the JOBS Act

This paper examines the impact of the recently passed JOBS Act on the behavior of market participants. Using the JOBS Act - which relaxed mandatory information disclosure requirements - as a natural experiment on firms' choices of the optimal mix of hard, accounting information and textual disclosures, we find that relative to a peer group of firms, IPO firms reduce accounting disclosures and change textual disclosures. Because it allows a partial revelation of IPO quality, only textual disclosures affect underpricing. We also find that the SEC changes its behavior post-JOBS Act in responding to draft registration statements. Specifically, the SEC's comment letters to firms are more negative in tone, and more forceful in their recommendations, focusing on quantitative information. Finally, under the JOBS Act, investors place more emphasis on the information produced by the SEC when pricing the stock. Returns following public release of the letters vary by about 4% based on letter tone.
Structured least squares to improve the performance of ESPRIT-type algorithms

ESPRIT-type (spatial) frequency estimation techniques obtain their frequency estimates from the solution of a highly structured, overdetermined system of equations (the so-called invariance equation). Here, the structure is defined in terms of two selection matrices applied to a matrix spanning the estimated signal subspace. Structured least squares (SLS) is a new algorithm that solves the invariance equation by preserving its structure. Formally, SLS is derived as a linearized iterative solution of a nonlinear optimization problem. If SLS is initialized with the least squares solution of the invariance equation, only one "iteration", i.e. the solution of one linear system of equations, is performed to achieve a significant improvement of the estimation accuracy. Therefore, the proposed estimation scheme (that uses only one "iteration" of SLS) is not iterative in nature.
A Model for Usability in E-Commerce Services: Theoretical Concept and Empirical Evidence

B2C (Business-to-Consumer) e-commerce, which involves the marketing and distribution of products and services to consumers via the Internet, has advantages both for retailers and consumers. Among others, consumers are able to shop at any time, do not have expenses for driving to shops, and goods are directly delivered to their homes. It is therefore not surprising that market and consumer studies indicate that US online retail sales accounted for almost 9% of the $3.2 trillion total retail market in 2013 and will continue to grow at a compound annual growth rate of nearly 10% through 2018. (Forrester Research, 2014). An important factor in the B2C e-commerce success is the usability of the shopping interface, which refers to a website`s ability to be used to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use (ISO 9241-11; Venkatesh & Agarwal, 2006). Theory and research suggest that usability is critical for the adoption or rejection of e-commerce applications in several fields of application (e.g., Pavlou & Fygenson, 2006; Song & Zahedi, 2005). Despite the significance of usability in product oriented B2C e-commerce (Koufaris, Kambil, & La Barbera, 2002; Pavlou & Fygenson, 2006; Song & Zahedi, 2005) as well as in B2B (Business-to-Business) e-commerce, which make use of Internet and web technologies for interorganizational business transactions (e.g., Konradt, Lueckel, & Ellwart, 2012), effects have rarely been demonstrated for online suppliers of services. E-commerce of services refers to the purchase and sales of services via electronic channels, such as the Internet. Even though the difference between services and products or goods is not always clear-cut and distinctive, services are intangible and production and consumption of services cannot be separated (de Jong & Vermeulen, 2003). Because of these characteristics, services are considered to be high in so-called credence qualities, which consumers find difficult to evaluate. Hence, they must rely on the supplier to be served properly. Physical goods, in contrast, are high in search qualities and experience qualities. That is, customers are able to assess the quality of products before a final purchase and make valid experience-based evaluations afterwards. This kind of evaluation is not possible in e-commerce of services, and consumers have to collect other cues for information that promise service quality, for example, the usability of the e-commerce website for services.

Influence of managers personal values and ethical behaviour on business success of hotel enterprises

Understanding ethical/unethical conduct is difficult, given that the ethical/unethical choice of actions is under the influence of different personal values. Individuals are strongly and permanently stimulated towards a specific action, and their cultural background also contains a framework for permitted and prohibited behavior. The purpose of this paper is to assess the importance of terminal and instrumental values of top-level management, and to know what values motivate and direct the management of the most ethical/unethical behavior. This paper presents the results of empirical research of ethical/unethical behavior of top-level management and performance indicators in large hotel enterprises in Croatia. Data analysis used descriptive statistical analysis, Fisher's test, rank correlation, Spearman's rank correlation coefficient, analysis of variance (ANOVA) and analysis of reliability. The obtained results confirmed the academic hypothesis: “Top-level management of large hotel enterprises in the Republic of Croatia who opt for an ethical progress of behaviour achieve better business results in the long term than those who opt for a non-ethical progress of behaviour. ” The role of strategic managers in promoting ethical conduct as well as establishing and implementing ethical values in enterprises has strengthened, while understanding the relationship between ethical behaviour and business success indicators paved the way for creating and enforcing ethical business policies and strategies in the process of strategic management, in order to ensure economic progress.
Scientific communities detection and analysis in the bibliographic database: SCOPUS

In recent years, Governments of many countries had promoted higher education in exclusive areas and disciplines to improve the quality of inhabitant's life, economy, and public management. However, there is no an effective way to help governments to verify if scientific works and research centers are aligned to a country priority research area. A dataset of 4552 scientific works associated to 29 research areas in Ecuador was collected from a bibliographic database SCOPUS. This work is focused on detection of the most important Ecuadorian research areas based on scientific collaboration in scientific publications in such areas through a proposed methodology. The methodology is subject to Social Network Analysis and Natural Language Processing to identify collaboration communities and the most relevant topics on densely connected communities. Finally, an exploratory analysis of a case study thought this methodology is presented to demonstrate that is possible to know which scientific areas are the most collaborative and which topics were the most popular in Ecuador.
Reduced Plasma Eicosapentaenoic Acid–Arachidonic Acid Ratio in Peripheral Artery Disease

A reduced ratio of plasma eicosapentaenoic acid–arachidonic acid (EPA-AA) is a newly recognized atherosclerotic risk factor. This ratio has not been fully investigated in peripheral artery disease (PAD). Seventy Japanese patients with atherosclerotic risk factors were enrolled and divided into 2 groups, those with PAD (group A: n = 38) and those without PAD (group B: n = 32). The EPA-AA ratio (P = .001) and ankle–brachial index (ABI: P < .001) in group A were significantly lower than those in group B. Univariate and multivariate analyses demonstrated that EPA-AA, ABI, and prescription of clopidogrel had significant correlation with PAD. Given the appropriate cutoff values, EPA-AA (odds ratio [OR] = 11.7, 95% confidence interval [CI] = 3.0-45.8; P < .001) and ABI (OR = 44.0, 95% CI = 5.4-358.5; P < .001) are factors independently associated with PAD. In conclusion, this study demonstrated that reduced plasma EPA/AA may underlie PAD at least in Japanese.
An Information Retrieval Expansion Model Based on Quasi-Clique

Q uery expansion is an important technology for improving retrieval performance in information retrieval. Many Studies have found contexts within query that strongly influence the interpretation of a query. In this paper, we propose the graph mining technique called Quasi-Clique as query context in Markov network retrieval model. Our approach exploits contextual information mined from the term Markov network for per query term in addition to syntactic similarity. The proposal in our work is benefit to select more relevant terms for query expansion and to improve precision in information retrieval. Keywords—information retrieval; query expansion; quasi- clique; Markov network retrieval I. INTRODU CTION
The determinants and consequences of disclosure committee adoption

After the passage of the Sarbanes-Oxley Act of 2002, the Securities and Exchange Commission recommended that companies voluntarily adopt disclosure committees to aid in preparing company disclosures. In this paper, I investigate the determinants and consequences of disclosure committee adoption. I find that companies with material weaknesses in internal controls over financial reporting and less readable 10-K filings are more likely to adopt disclosure committees. In consequences analyses, using a propensity score matched control sample and a difference-in-differences research design, I find that 10-K filings are longer and less readable after disclosure committee adoption. However, consistent with institutional theory, I do not find evidence of a reduction in information asymmetry or an increase in the informativeness of earnings following disclosure committee adoption.
