The Effect of Emotional Valence on Memory Quality and Confidence Judgements

In the present study, our aim was to investigate how emotional valence influences the recollective experience and confidence judgements of memory. We also investigated if subliminal manipulation can have a valence dependent effect on the realism in confidence judgements. In Experiment 1, the first phase involved participants being shown pictures and asked to select the pictures that had either negative or positive valence. In the test phase, participants decided first if the picture was "old" or "new", after which they made confidence judgements of their responses. Pictures reported as "old" was finally appraised on the quality of the memory trace; if subjects "remembered", "knew" or "guessed" that they had previously seen the picture. Experiment 2 was conducted in the same fashion, with the exception of a subliminal presentation preceding each picture in the test phase, which was expected to cause an increase in "know" responses. The results were partly in line with previous research. Significant results were obtained for the confidence variable, showing that subjects were more confident in their responses with negative images. Albeit not significant, the results showed that recollective experience was somewhat higher for negative valence than for positive. It is also discernable that subliminal manipulation of fluency lead to an increase in familiarity, although it did not influence realism in confidence judgements.
GEEZERS, GREED, GRIEF, AND GRAMMAR: FRAME TRANSFORMATION IN THE NURSING HOME REFORM MOVEMENT

This study examines research on framing processes in the senior rights movement under the veil of social constructionism. It focuses on the emergence of the nursing home reform movement that led to the formation of the National Citizens' Coalition for Nursing Home Reform (NCCNHR) and the passing of the Omnibus Budget Reconciliation Act of 1987. The research uses content analysis to examine data from six major U.S. newspapers to examine media images of the NCCNHR. Findings suggest that a frame transformation process has countered a recent period of abeyance in the nursing home reform movement. The analysis of media images of the NCCNHR contributes to social movement research examining framing processes and abeyance.
Topological Persistence and Simplification

AbstractWe formalize a notion of topological simplification within the framework of a filtration, which is the history of a growing complex. We classify a topological change that happens during growth as either a feature or noise depending on its lifetime or persistence within the filtration. We give fast algorithms for computing persistence and experimental evidence for their speed and utility.
Stroboscopic observation of a random walker

The patterns of motion of mobile agents have received recently wide attention in the literature. There is a number of recent studies centered around the motion behavior of many agents ranging from albatrosses to human beings. Special attention has been given to the covered distances statistical distributions. In some cases, due to the lack of accurate data about the motion of the agents it has been necessary to plan very clever experiments to obtain them. These experiments try to infer the statistical properties of the agents' real motion from the observed positions in consecutive time intervals. The length of the time intervals are random variables taking their values from a previously known statistical distribution or from a distribution deduced from empirical data. The aim of this work is to demonstrate that for a Gaussian Random Walker it is, in general, impossible to recover the real motion patterns distribution from the stroboscopic observation of the agents unless the length of the intervals between two consecutive measurements are equal. Moreover, it is also shown that the distances distribution strongly depends on the agents' observation time intervals. These claims are sustained by numerical experiments.
Voxel-Based Dipole Orientation Constraints for Distributed Current Estimation

Distributed electroencephalography source localization is a highly ill-posed problem. With measurements on the order of 102, and unknowns in the range of 104-105, the range of feasible solutions is quite large. One approach to reducing ill-posedness is to intelligently reduce the number of unknowns. Restricting solutions to gray matter is one approach. A further step is to use the anatomy of each patient to identify and constrain the orientation of the dipole within each voxel. While dipole orientation constraints for cortical patch-based approaches have been proposed, to our knowledge, no solutions for full volumetric localizations have been presented. Patch techniques account for patch surface area, but place dipoles only on the surface, rather than throughout the cortex. Variability in human cortical thickness means that thicker regions of cortex will potentially contribute more to the EEG signal, and should be accounted for in modeling. Additionally, patch models require cortical surface identification techniques, which can separate them from the extensive literature on voxel-based MR image processing, and require additional adaptation to incorporate more complex information. We present a volumetric approach for computing voxel-based distributed estimates of cortical activity with constrained dipole orientations. Using a tissue thickness estimation approach, we obtain estimates of the cortical surface normal at each voxel. These let us constrain the inverse problem, and yield localizations with reduced spatial blurring and better identification of signal magnitude within the cortex. This is demonstrated for a series of simulated and experimental data using patient-specific bioelectric models.
Monolithic Four-Channel (QUAD) Integrated Widely Tunable Transmitter in Indium Phosphide

Tunable and array-based multichannel chip-scale optical transmitter devices have revolutionized the pluggable module telecom market, by enabling excellent performance with great cost and size reduction. In this paper, we report on a novel, four-channel, monolithic widely tunable transmitter device (QUAD) in indium phosphide. This device is based on monolithic integration of four widely tunable externally modulated lasers, with a single output waveguide. The QUAD device is designed to operate at 55 °C, in order to reduce the power consumption of the cooler. A full QUAD module was developed and characterized, demonstrating 10 Gb/s simultaneous operation of all four transmitters, with >30 nm tuning range, and error-free operation. Through system-level experiments, the regenerative nature of the QUAD transmitter has been demonstrated.
Improving Density Estimation by Incorporating Spatial Information

Given discrete event data, we wish to produce a probability density that can model the relative probability of events occurring in a spatial region. Common methods of density estimation, such as Kernel Density Estimation, do not incorporate geographical information. Using these methods could result in nonnegligible portions of the support of the density in unrealistic geographic locations. For example, crime density estimation models that do not take geographic information into account may predict events in unlikely places such as oceans, mountains, and so forth. We propose a set of Maximum Penalized Likelihood Estimation methods based on Total Variation and Sobolev norm regularizers in conjunction with a priori high resolution spatial data to obtain more geographically accurate density estimates. We apply this method to a residential burglary data set of the San Fernando Valley using geographic features obtained from satellite images of the region and housing density information.
On Random Coding Error Exponents of Watermarking Codes

steganography, watermarking, information hiding, error exponent, random coding Watermarking codes are analyzed from an informationtheoretic viewpoint as a game between an information hider and an active attacker. While the information hider embeds a secret message (watermark) in a covertext message (typically, text, image, sound, or video stream) within a certain distortion level, the attacker processes the resulting watermarked message, within limited additional distortion, in an attempt to invalidate the watermark. For a memoryless covertext source, we provide a single-letter characterization of the minimax-maximin game of the random coding error exponent associated with the average probability of erroneously decoding the watermark. This single-letter characterization is in effect because there is a “memoryless saddle point” in this game: The information hider utilizes a memoryless channel to generate random codewords for every covertext message, whereas the attacker implements a memoryless channel to disrupt the watermark information hidden in the covertext.
IFN-γ Induces Apoptosis in Ovarian Cancer Cells in Vivo and in Vitro

Purpose: The purpose of this study was to compare in vitro and in vivo responses of primary human tumor cells to IFN-γ. Experimental Design: IFN-γ may have therapeutic activity in patients with ovarian cancer. We showed previously that this cytokine had direct antiproliferative activity against human ovarian cancer cell lines and xenografts in nude mice. To further understand the role of IFN-γ in ovarian cancer, we compared its action on 8 ovarian cancer cell lines with the response of 14 primary cultures of ovarian tumor cells isolated from patients with ascitic disease. A pilot clinical study was then conducted to see whether IFN-γ would also induce apoptosis in human tumor cells in vivo. Six patients with ascites and advanced disease were given IFN-γ by i.p. injection, and sequential samples of ascites were analyzed. Results: IFN-γ had antiproliferative activity in 8 of 8 ovarian cancer cell lines and 11 of 14 primary cultures. This activity was dose related, and cleaved poly(ADP-ribose) polymerase in protein isolates provided evidence of apoptosis. In the clinical study, there was a 3 log10 pharmacokinetic advantage in peritoneal compared with plasma levels of IFN-γ. In two of six patients, there was a 90% reduction in tumor cells in ascites after IFN-γ treatment, and this was related to clinical benefit as assessed by intervals between paracentesis. In all six patients, there were increased amounts of cleaved poly(ADP-ribose) polymerase in protein extracts of ascitic cells sampled during IFN-γ treatment. Conclusions: IFN-γ induces apoptosis in vitro and in vivo in human epithelial ovarian cancer.
Peroxidase-like activity of nanocrystalline cobalt selenide and its application for uric acid detection

Dendrite-like cobalt selenide nanostructures were synthesized from cobalt and selenium powder precursors by a solvothermal method in anhydrous ethylenediamine. The as-prepared nanocrystalline cobalt selenide was found to possess peroxidase-like activity that could catalyze the reaction of peroxidase substrates in the presence of H2O2. A spectrophotometric method for uric acid (UA) determination was developed based on the nanocrystalline cobalt selenide-catalyzed coupling reaction between N-ethyl-N-(3-sulfopropyl)-3-methylaniline sodium salt and 4-aminoantipyrine (4-AAP) in the presence of H2O2. Under optimum conditions, the absorbance was proportional to the concentration of UA over the range of 2.0–40 μM with a detection limit of 0.5 μM. The applicability of the proposed method has been validated by determination of UA in human serum samples with satisfactory results.

Positive and negative emotions recognition from speech signal using acoustic and lexical features

This paper aims to present the work on emotion recognition in Indonesian spoken language. For this effort, we construct Indonesian Emotional Corpus (IDEC). In constructing the corpus, we aim at natural emotional occurrences. We choose television talk shows due to its natural emotional content. We extract two types of features from IDEC: acoustic and lexical features. We employ Support Vector Machine (SVM) and Random Forest algorithm to model the emotions utilizing these two types of features. Experiment result shows an average F-measure of 0.772 at best for 2 emotion classes based on valence dimension. We hope to continue this work and move towards more precise emotion recognizer by collecting more data, incorporating other features, and defining more complex emotion classes.
In Their Own Words and by the Numbers: A Mixed-Methods Study of Latina Community College Presidents

In 2006, only 26 Latina CEOs served in associate degree colleges, primarily at Hispanic-serving institutions. In spite of the gains made by women in higher education, equity in the representation of Latinas in higher education at the highest administrative ranks has not been achieved. The primary purpose of this research was to learn from Latina community college presidents about their experiences on the pathway to the presidency. This mixed methods study examined the career paths and early influences, as well as external forces that converged to support their ascent to being presidents and chancellors. The conditions and experiences examined were (a) influences that Latina community college presidents identified as having the most impact on personal career success, (b) strategies Latinas have employed to overcome barriers or challenges on the pathway to the presidency, and (c) the organizational climate and practices within community colleges that either hinder or support Latinas. The convergence of these conditions was analyzed to determine effective strategies to support Latinas in achieving leadership roles. The following themes emerged from the findings: personal context, professional preparation, professional context, and challenges and the leadership pipeline. The findings suggest that trustees played a critical role in promoting diversity. Moreover, although systemic barriers exist, the Latina presidents in this study refused to allow bias to prevent them from succeeding. Recommendations for further studies and implications for developing Latinas to gain access to the leadership pipeline were discussed in the findings.

Primary Synovial Sarcoma of the Thyroid Gland

Synovial sarcoma is a rare but distinct soft tissue neoplasm, most commonly occurring in para-articular regions of the extremities of young adults and also occurring in the head and neck region. To the best of our knowledge, only one case of primary synovial sarcoma of the thyroid has been previously reported. Here, we report a 15-yr-old man who had a chief complaint of a palpable neck mass. The neck computed tomography revealed a relatively well-demarcated solid mass in the left thyroid gland. After fine needle aspiration cytology, total thyroidectomy and lymph node dissection were performed. Grossly, the mass was covered by the same capsule as the thyroid gland, measuring 6×5×5 cm in dimensions and weighing 78 gm. The cut surface showed a well demarcated, lobulated, grayish tan, and rubbery solid tumor. Histologically, this tumor was a biphasic synovial sarcoma. Immunohistochemical, ultrastructural, genetic studies, and cytologic findings were all consistent with synovial sarcoma. When synovial sarcomas arise in this unusual site, recognition and differential diagnosis become more difficult. The differential diagnosis of a spindle epithelial tumor with thymus-like differentiation is very difficult due to their similar clinical, histological, and immunohistochemical features. Ultrastructural and cytogenetic studies for synovial sarcoma are necessary to establish a definitive diagnosis.
Exploiting Language Variants Via Grammar Parsing Having Morphologically Rich Information

In this paper, the development and evaluation of the Urdu parser is presented along with the comparison of existing resources for the language variants Urdu/Hindi. This parser was given a linguistically rich grammar extracted from a treebank. This context free grammar with sufficient encoded information is comparable with the state of the art parsing requirements for morphologically rich and closely related language variants Urdu/Hindi. The extended parsing model and the linguistically rich grammar together provide us promising parsing results for both the language variants. The parser gives 87% of f-score, which outperforms the multi-path shift-reduce parser for Urdu and a simple Hindi dependency parser with 4.8% and 22% increase in recall, respectively.
Motivations and Obstacles for Seniors to Adopt Social Network Services

In light of the analysis framework including Political and governmental support, Economical and commercial support, Social and communities support and Technology support (PEST), this study identified motivations and obstacles for seniors’ use of social network services (SNS). Scenario simulation interviews based on four steps in which the seniors built strategies for learning about social media, were conducted through focus groups in China to determine the main motivations and obstacles for their adoption of SNS. Each interview included three sections – a) Introducing, b) Responding, and c) Engagement – and each participant was provided with a personal device. Theoretically, the study focused on exploring the model of motivation, psychological and physical difficulties for seniors’ adoption of SNS. Drawing on the model of continuous online SNS usage, we developed a model consists of motivation and obstacles for seniors’ SNS adoption and tested the model using the focus-group interview method. The results revealed that seniors’ SNS adoption is determined more strongly by negative social influences than by positive social influences. The results also indicated that while the main motivation for seniors’ SNS adoption involves communication convenience and social connections, the obstacles are related to negative social influences and to the physical and psychological barriers of technology usage.

A Proposal of Practices, Processes and Models That Enable Innovation Potential

Innovation is neither predictable nor guaranteed within a solution development project. Novel ideas can appear during any level of work, whether high-level design or in code algorithms. As design innovation is a creative action, this paper proposes a vision of related practices, processes and modeling ideas that enable innovation to potentially happen. The practices are mostly mental techniques for a designer to use which help to maintain an open mind to solution possibilities. The process approaches are based on and support progress within a flexible, incremental and iterative methodology that can respond to new ideas. The modeling technique ideas strive to support the clear communication of understanding and the evolution of the design through multiple alternatives. The proposals suggested are rooted in some successes from actual industry projects over the years, but can benefit from further research and empirical evaluation.
Program analysis and transformation for holistic optimization of database applications

We describe DBridge, a novel program analysis and transformation tool to optimize database and web service access. Traditionally, rewrite of queries and programs are done independently, by the database query optimizer and the language compiler respectively, leaving out many optimization opportunities. Our tool aims to bridge this gap by performing holistic transformations, which include both program and query rewrite. There has been earlier research in this area involving program analysis and transformation for automatically rewriting database applications to perform optimizations; for example, our earlier work has addressed batching or asynchronous submission of iterative queries, and prefetching query results. DBridge implements these techniques for Java programs and internally uses Soot, a Java optimization framework, for static analysis and transformation. DBridge can perform such optimizations on Java programs that use the JDBC API to access the database. It is currently being extended to handle the Hibernate API, and Web Services. In this paper, we describe the program transformations that DBridge can perform. We then discuss the design and implementation of DBridge with a focus on how the Soot framework has been used to achieve these goals. Finally, we conclude by discussing some of the future directions for our tool.
Intraischemic Nitrous Oxide Alters Neither Neurologic Nor Histologic Outcome: A Comparison with Dizocilpine

N-Methyl-d-aspartate receptor antagonism contributes to the anesthetic action of nitrous oxide (N2O). We examined the effects of the N-methyl-d-aspartate antagonists N2O and dizocilpine on outcome from filament occlusion of the middle cerebral artery (MCAO). Rats breathed 70% nitrogen/30% oxygen or 70% N2O/30% oxygen during MCAO. A third group breathed 70% nitrogen/30% oxygen and was given dizocilpine (0.25 mg/kg IV). After 75 min of MCAO, the rats recovered for 3 or 14 days. Pericranial temperature was maintained at 37.5°C ± 0.2°C during ischemia and for 20 h postischemia. N2O did not alter neurologic scores at 3 days (N2O, 21 ± 6; nitrogen, 22 ± 8; P = 0.95; 0 = normal; 48 = maximal deficit; mean ± sd; n = 15) or 14 days (N2O, 13 ± 6; nitrogen, 12 ± 6; P = 0.93; n = 15–16) postischemia. N2O had no effect on infarct size at 3 days (N2O, 162 ± 45 mm3; nitrogen, 162 ± 61 mm3; P = 0.99) or 14 days (N2O, 147 ± 56 mm3; nitrogen, 151 ± 62 mm3; P > 0.99) postischemia. Dizocilpine treatment caused smaller infarcts (3 days: 66 ±49 mm3, P < 0.0001 versus nitrogen; 14 days: 84 ± 50 mm3, P < 0.006 versus nitrogen) and reduced the neurologic deficit (3 days: 10 ±10, P =0.002 versus nitrogen; 14 days: 6 ± 7, P = 0.006 versus nitrogen). N2O (70%) had no effect on either behavioral or histologic outcome from transient focal cerebral ischemia when compared with results in rats breathing 70% nitrogen. These results indicate that normobaric N2O does not alter the response of rat brain to a focal ischemic insult.
