THE HIGH CROSS-COUNTRY CORRELATIONS OF PRICES AND INTEREST RATES

We document that, at business cycle frequencies, fluctuations in nominal variables, such as aggregate price levels and nominal interest rates, are substantially more synchronized across countries than fluctuations in real output. To the extent that domestic nominal variables are determined by domestic monetary policy, and central banks generally attempt to keep the domestic nominal environment stable, this might seem surprising. We ask if a parsimonious international business cycle model can account for this aspect of cross-country aggregate fluctuations. It can. Due to spillovers of technology shocks across countries, expected future responses of national central banks to fluctuations in domestic output and inflation generate movements in current prices and interest rates that are synchronized across countries even when output is not. Even modest spillovers produce cross-country correlations such as those in the data.
Purification of a cysteine proteinase from Carica candamarcensis L. and cloning of a genomic putative fragment coding for this enzyme.

We describe the purification of a cysteine proteinase from latex of Carica candamarcensis, hereby designated CC23. The enzyme has been purified by ion-exchange chromatography and behaves electrophoretically as a monomer of M(r) 23,000 and optimal pH of 8.0. It displays a basic isoelectric point, has one cysteine residue in the active site by titration with E-64, confirmed by DNA sequencing, and responds to proteinase inhibitors as a classic cysteine proteinase. The K(m) and k(cat)/K(m) for CC23 using BAPNA were respectively 14.7 +/- 1.8 x 10(-4) M and 1.3 x 10(3) M(-1) s(-1). Therefore, the catalytic efficiency of CC23 is sixfold higher than that of CC-I, another proteinase from the same plant. DNA primers were designed to amplify by PCR a genomic sequence related to this enzyme. An 895-bp DNA fragment was cloned and sequenced. It shows strong homology with chymopapain isoform IV from C. papaya. The translated sequence is similar to that of chymopapain isoform II (73%) and CC-III (77%) from C. candamarcensis.
Multiple Uses of Mental Imagery by Professional Modern Dancers

The present qualitative study has revealed a range of mental imagery strategies which professional modern dancers used for different purposes during their training, during the creation and rehearsal of a choreography, as well as prior to, during, and after a performance. The dancers' use of imagery tended to be multi-modal, multi-dimensional, seeking to integrate mind, body, and spirit not only in their dance activities but also in their lifestyle. Many of these personalized images had common characteristics and similar effects, which made possible their organization into eight imagery categories: inspiration, atmospheric, specific movement, metaphysical, emptying out, filling up, projection, and imagery rehearsal. Suggestions are made for the inclusion of similar types of images into the dance classroom and into other movement contexts.
Selling (out) the Sporting Woman: Advertising Images in Four Athletic Magazines

This study examines the presentation of women in advertising photographs published in four women’s sports and fitness magazines in order to ascertain the presence of sexual difference and differentiate between advertising messages in the magazines. Researchers found strong support for sexual difference in advertisements contained in fitness-oriented magazines, and, at the other end of the spectrum, rejection of sexual difference in magazines that emphasized competitive sport. The advertising images generally provided mixed messages in regard to sexual difference. The authors suggest that the continued use of sexual difference in sport advertising images is a function of commodity feminism, which serves the capitalist hegemony. The authors discuss the need for visual representations that are truly feminist.
Longitudinal Effects of the Arkansas Better Chance Program: Findings from Kindergarten and First Grade

Acknowledgements Many thanks are due to our colleagues at Partners for Inclusive Communities at the University of Arkansas for Medical Sciences (UAMS), who partnered with us to carry out this study: Dr. Leanne Whiteside-Mansell, Yvonne Bradshaw, and their field staff. We greatly appreciate assistance from Paul Lazenby, Tonya Russell, and Jamie Morrison at the Arkansas Division of Child Care and Early Childhood Education, as well as the many school administrators and teachers in Arkansas who made this research possible. Thanks to Dr. Ellen Frede at NIEER for her ongoing advice on conducting a longitudinal study of state pre-K, and to Amanda Colon and Jessica Thomas for data management and coordination at NIEER. Finally, we are especially grateful to the kindergartners and first graders who took time out of their school days to participate in our ongoing study. started a 5-year longitudinal study of the Arkansas Better Chance (ABC) prekindergarten program. A goal of this work is to estimate the effects of state-funded pre-K in Arkansas on children's language, mathematics, and literacy skills through fourth grade. Our study has two complementary components: a conventional statistical comparison of ABC children with children who did not participate in pre-K, and a sophisticated regression-discontinuity design (RDD) that estimates the effects of ABC participation at kindergarten entry. The advantage of the RDD is that it eliminates the threat of selection bias, which arises when there are initial differences between children who participate in a preschool program and those who do not. RDD findings presented in an earlier report show that ABC has statistically significant positive impacts on children's language, math, and early literacy skills at kindergarten entry. The RDD approach cannot be used beyond kindergarten entry, however, so it is necessary to also use a conventional approach when examining longer term effects of pre-K. The conventional approach has the advantage of allowing us to estimate the effects of ABC as children progress through elementary school. Data from the RDD and conventional approaches can then be compared to estimate the effects of selection bias on the conventional results. In the current report, we present data about classroom quality in the ABC program, as classroom quality is likely a key factor through which prekindergarten programs produce positive effects for children. Findings from structured classroom observations using standardized measures of overall quality, classroom support for early literacy, and classroom support for mathematics were generally positive. Overall classroom quality …
Applications of the virtual cellular machine to many-core processors

There is a large variety of multi- and many-core platforms but established design methodologies for such processor arrays are still missing. We propose the concept of virtual cellular machine as an architecture, which does not correspond necessarily to a physical device, built according to the specific requirements needed by the programmer. The features of a virtual cellular machine (processors, memories etc.) can then be mapped onto existing physical many-core processors.
Screening for psychiatric disorders in an area affected by the Chernobyl disaster: the reliability and validity of three psychiatric screening questionnaires in Belarus

Synopsis The reliability and criterion validity of Russian versions of three psychiatric screening questionnaires (the General Health Questionnaire, 12-item version; the Goldberg scales for anxiety and depression; and, the Bradford Somatic Inventory) were assessed in the Gomel region (Belarus), one of the most severely contaminated areas that resulted from the nuclear power plant explosion at Chernobyl in 1986. All instruments were found to have good internal reliability indices. Retest reliability of the GHQ, not tested for in the other instruments, was modest. Criterion validity, using a semi-structured interview on the basis of the Munich Diagnostic Checklist for DSM-III-R as external criterion, was good for the Goldberg scales, but modest for the two other instruments.
Heterogeneity in sarcoma cell lines reveals enhanced motility of tetraploid versus diploid cells

Soft tissue sarcomas with complex genomics are very heterogeneous tumors lacking simple prognosis markers or targeted therapies. Overexpression of a subset of mitotic genes from a signature called CINSARC is of bad prognosis, but the significance of this signature remains elusive. Here we precisely measure the cell cycle and mitosis duration of sarcoma cell lines and we found that the mitotic gene products overexpression does not reflect variation in the time spent during mitosis or G2/M. We also found that the CINSARC cell lines, we studied, are composed of a mixture of aneuploid, diploid, and tetraploid cells that are highly motile in vitro. After sorting diploid and tetraploid cells, we showed that the tetraploid cell clones do not possess a proliferative advantage, but are strikingly more motile and invasive than their diploid counterparts. This is correlated with higher levels of mitotic proteins overexpression. Owing that mitotic proteins are almost systematically degraded at the end of mitosis, we propose that it is the abnormal activity of the mitotic proteins during interphase that boosts the sarcoma cells migratory properties by affecting their cytoskeleton. To test this hypothesis, we designed a screen for mitotic or cytoskeleton protein inhibitors affecting the sarcoma cell migration potential independently of cytotoxic activities. We found that inhibition of several mitotic kinases drastically impairs the CINSARC cell invasive and migratory properties. This finding could provide a handle by which to selectively inhibit the most invasive cells.

A user-friendly college recommending system using user-profiling and matrix factorization technique

Currently in India college ranking is the issue that is discussed a lot. In this paper, a common forum where students can get information about various engineering colleges and their ranking. There are many websites that give information about various engineering colleges but when it comes to students, for them it is important to know certain insights to parameters like faculty, campus life, hostel facility, placement etc. Students from small cities and villages have less exposure to various Colleges which are funded by state and central government for studies, Research and Innovation. If these students will have sufficient exposure then the young talent will be properly channelized as per their interest. In this we have developed a recommender system that understands information seeker need and accordingly generates recommendations for him/her through simple interface, which provides information to the students and advisors to improve the choice of courses. In our methodology we have opted for hybrid approach which combines advantages of Collaborative filtering algorithm and Content based filtering algorithm to improve our recommendations. The system consists of an interactive User Profiling [9] process in order to construct profile of the User. As the sample datasets that are used for experiments are large and also contain more number of feature sets, it is essential to understand dataset beforehand. Recommending items based on the users interest requires processing of these large datasets, thus if this information is properly profiled then the task of recommending would get a lot easier. Also when results are shown to the user, big challenge is how well data can be ranked so that user satisfaction is guaranteed.
Multipair Massive MIMO Relaying With Pilot-Data Transmission Overlay

We propose a pilot-data transmission overlay scheme for multipair massive multiple-input multiple-output (MIMO) relaying systems employing either half-duplex or full-duplex (FD) communications at the relay station (RS). In the proposed scheme, pilots are transmitted in partial overlap with data to decrease the channel estimation overhead. The RS can detect the source data with minimal destination pilot interference by exploiting the asymptotic orthogonality of massive MIMO channels. Then pilot-data interference can be effectively suppressed with the assistance of the detected source data in the destination channel estimation. Due to the transmission overlay, the effective data period is extended, hence improving system throughput. Both theoretical and simulation results confirm that the proposed pilot-data overlay scheme outperforms the conventional separate pilot-data design in the limited coherence interval scenario. Moreover, at asymptotically high and low SNR regions, the proposed scheme is superior regardless of the coherence interval length. Because of simultaneous transmission, the proper power allocation of source data transmission and relay data forwarding can further improve the system performance. Hence a power allocation problem is formulated and a successive convex approximation approach is proposed to solve the non-convex optimization problem with the FD pilot-data transmission overlay.
Ativos intangíveis, ciclo de vida e criação de valor

The economic value of a company is a result of the sum of its tangible and intangible assets. The placing of significant importance on companies that use intangible assets intensively has shown the growing importance of these assets in the maintenance of their competitive advantages, and consequently of their economic values. This outlook is consistent with the Resource-based View. The relative influence of intangible assets on the value of companies can vary for several reasons: due to the industry, the life cycle of the product and company, the mission of companies and others. The main objective of this essay is to develop a theoretical analysis of the strategies that companies can develop in relation to their intangible assets, especially taking into account issues related to the life cycle of the product. In other words, the objective is to analyze how the life cycle can affect the strategies concerning each type of intangible asset, and consequently, the value creation process. The analysis suggests that different intangible assets influence the value of the company, depending on the life cycle phase of a given product.
Frugal storage for cloud file systems

Enterprises are moving their IT infrastructure to cloud service providers with the goal of saving costs and simplifying management overhead. One of the critical services for any enterprise is its file system, where users require real-time access to files. Cloud service providers provide several building blocks such as Amazon EBS, or Azure Cache, each with very different pricing structures that differ on the basis of storage, access and bandwidth costs. Moving an entire file system to the cloud using such services is not cost-optimal if we rely on only one of these services. In this paper, we propose FCFS, a storage solution that drastically reduces the cost of operating a file system in the cloud. Our solution integrates multiple storage services and dynamically adapts the storage volume sizes of each service to provide a cost-efficient solution with provable performance bounds. Using real-world large scale data sets spanning a variety of work loads from an enterprise data center, we show that FCFS can reduce file storage and access costs in current cloud services by a factor of two or more, while allowing users to utilize the benefits of the various cloud storage services.
Interference suppression in synthesized SAR images

Radio interferences are becoming more and more an important source for image degradation in synthetic aperture radar (SAR) imaging. Especially at longer wavelengths, interferences are often very strong, and their suppression is required during data processing. However, at shorter wavelengths, interferences are often not obvious in the image amplitude, and filtering is not performed in an operational way. Nevertheless, interferences might significantly degrade the image phase, and the estimation of sensitive parameters like interferometric coherence or polarimetric descriptors becomes imprecise. Interference suppression is usually performed on the raw data, which are in most cases not available to the end-user. In this letter, a new interference suppression method for focused SAR images is proposed. Its performance is tested on interferometric repeat-pass data acquired by the German Aerospace Agency's experimental SAR system (E-SAR) at L-band.
The Effect of NIBRS Reporting on Item Missing Data in Murder Cases

The Uniform Crime Reporting Program (UCR) is undergoing a large-scale conversion from the traditional summary system and its Supplementary Homicide Reports (SHR) to the National Incident-Based Reporting System (NIBRS). One goal in designing NIBRS was to improve the quality of crime data. Little is known about the actual effect of the substantial changes in data collection instituted by NIBRS. Gaining this understanding is important for homicide researchers, as more states and law enforcement agencies replace the SHR with NIBRS data collection. This article measures data quality in terms of itemmissing data and compares the amount of missing murder characteristics in NIBRS with the SHR. The findings obtained are inconsistent. Depending on the characteristic, missing data in NIBRS decreased, increased, or remained relatively unchanged. These results reveal that despite the changes in NIBRS, the UCR continues to struggle with capturing information known to police and collecting particular incident details such as victim-offender relationship and circumstance.
A boundary-element approach to transient simulation of three-dimensional integrated circuit interconnect

The authors demonstrate that boundary-element techniques can be used to perform very efficient transient simulation of three-dimensional interconnect structures, fast enough to easily be included in a circuit simulator. Two boundary element approaches are investigated, and it is shown that the most straight-forward approach leads to unacceptable discretization errors and a less intuitive second approach yields good results even with coarse surface meshes. Results of numerical experiments demonstrating the effectiveness of the second approach in calculating cross-talk are presented. <<ETX>>
A Survey on CryptoSteganography: A Multilayer Security Data Hiding

Now a days there is a challenges faced by Data or Information Security Field. We have to make this data free from harm during transmission. The primary aim is to make an application which enables sensible information by covering securely in statistically undetectable communication channel. The two important concepts of securely transmitting information or data over a medium like internet are Steganography and Cryptography. Steganography is the art of secure communication which aims to hide the secret or sensitive information into a cover medium while observing the least possible statistical detectability. Cryptography is a scheme which decodes secret messages into several encrypted forms and distributes them. These both are used to assure security. But none of them can simply satisfy the basic needs of security i.e. the properties such as robustness, undetectability and capacity etc. A new technique based on the merging of both Cryptography and Steganography which can be named as “Cryptosteganography” is necessary which overcomes each other’s limitations and make hard for the intruders to attack or steal sensitive information is being proposed. To provide again more security to this new technology of Cryptosteganography a newest methodology is added to it which can be named as “Multilayer Steganography”. This new technique makes use of two cover files to strongly hiding of the Crypto-Stego file for providing very strong security in transmission of important data. The problem of the size of file during transmission is also resolved by “Multilayer Cryptosteganography Compression”. Application of this extends the horizon of data and file embedding and secrecy of data. Thus the scope is better than the existing Cryptography and Steganography systems which only the operations of data hiding and message embedding in the file.
Academic Support by Significant Others and Educational Resilience in Mexican-Origin Ninth Grade Students From Intact Families

This study used dominance analysis to examine the relative importance of ninth grade, Mexican-origin adolescents' perceptions of academic support from significant others (i.e., mothers, fathers, teachers, and friends) in relation to aspects of academic success. Self-report and school record data were collected from 216 Mexican-origin adolescents living in intact families. The results revealed that teachers' academic support was the most salient predictor of academic satisfaction and grade point average for both female and male students. Academic support from the opposite-sex parent explained the most variation in academic motivation. Academic support from friends was least important in explaining academic outcomes. Implications for schools and educators are presented.
Effect of Ambient Temperature Variations on Positivity of Manual Fecal Immunochemical Tests

Introduction: In the United States, many fecal occult blood tests are mailed by patients to a laboratory for analysis. Hemoglobin is not stable in feces and can be affected by the heat. Effects of season and ambient temperature on fecal immunochemical tests (FITs) have demonstrated a decrease in positivity rates during the hottest season. Objective: To investigate the potential effect of the average of 4-day ambient maximum temperature variations on the positivity of a single sample, one-time Clinical Laboratory Improvement Amendments (CLIA)–waived FIT. Setting: Midwestern tertiary care hospital. Methods: Individuals scheduled for a colonoscopy were invited to complete a qualitative FIT prior to their colonoscopy in 2010 and 2011. FITs were read as positive or negative. Results: Valid FITs were received from 1026 individuals over 25 months. The positivity rate was 10.9%. The mean 4-day average of daily maximum ambient temperatures was calculated including the day of receipt for each sample. Fahrenheit temperatures ranged from 16.0 to 96.8. Based on the odds ratio of 1.04 with a confidence interval of 0.94 to 1.14 for a 10°F increase in temperature, there was no statistically significant evidence of an effect of the preceding maximum average 4-day ambient temperature on FIT positivity. Conclusion: No evidence was found that ambient temperature had an effect on positivity rate over a 25-month period using 4 different qualitative FIT products. Further analysis on effect of ambient temperatures is warranted for the automated FITs and CLIA-waived FITs, including liquid-vial and dry-slide FITs. Primary care providers need to be aware of potential adverse effects of FITs.
