Creating Scalable and Interactive Web Applications Using High Performance Latent Variable Models

In this project we outline a modularized, scalable system for comparing Amazon products in an interactive and informative way using efficient latent variable models and dynamic visualization. We demonstrate how our system can build on the structure and rich review information of Amazon products in order to provide a fast, multifaceted, and intuitive comparison. By providing a condensed per-topic comparison visualization to the user, we are able to display aggregate information from the entire set of reviews while providing an interface that is at least as compact as the "most helpful reviews" currently displayed by Amazon, yet far more informative.
Ca2+/Calmodulin–Dependent Protein Kinase Modulates Cardiac Ryanodine Receptor Phosphorylation and Sarcoplasmic Reticulum Ca2+ Leak in Heart Failure

Abnormal release of Ca from sarcoplasmic reticulum (SR) via the cardiac ryanodine receptor (RyR2) may contribute to contractile dysfunction and arrhythmogenesis in heart failure (HF). We previously demonstrated decreased Ca transient amplitude and SR Ca load associated with increased Na/Ca exchanger expression and enhanced diastolic SR Ca leak in an arrhythmogenic rabbit model of nonischemic HF. Here we assessed expression and phosphorylation status of key Ca handling proteins and measured SR Ca leak in control and HF rabbit myocytes. With HF, expression of RyR2 and FK-506 binding protein 12.6 (FKBP12.6) were reduced, whereas inositol trisphosphate receptor (type 2) and Ca/calmodulin–dependent protein kinase II (CaMKII) expression were increased 50% to 100%. The RyR2 complex included more CaMKII (which was more activated) but less calmodulin, FKBP12.6, and phosphatases 1 and 2A. The RyR2 was more highly phosphorylated by both protein kinase A (PKA) and CaMKII. Total phospholamban phosphorylation was unaltered, although it was reduced at the PKA site and increased at the CaMKII site. SR Ca leak in intact HF myocytes (which is higher than in control) was reduced by inhibition of CaMKII but was unaltered by PKA inhibition. CaMKII inhibition also increased SR Ca content in HF myocytes. Our results suggest that CaMKII-dependent phosphorylation of RyR2 is involved in enhanced SR diastolic Ca leak and reduced SR Ca load in HF, and may thus contribute to arrhythmias and contractile dysfunction in HF.
RFID-based human behavior modeling and anomaly detection for elderly care

This research aimed at building an intelligent system that can detect abnormal behavior for the elderly at home. Active RFID tags can be deployed at home to help collect daily movement data of the elderly who carries an RFID reader. When the reader detects the signals from the tags, RSSI values that represent signal strength are obtained. The RSSI values are reversely related to the distance between the tags and the reader and they are recorded following the movement of the user. The movement patterns, not the exact locations, of the user are the major concern. With the movement data (RSSI values), the clustering technique is then used to build a personalized model of normal behavior. After the model is built, any incoming datum outside the model can be viewed as abnormal and an alarm can be raised by the system. In this paper, we present the system architecture for RFID data collection and preprocessing, clustering for anomaly detection, and experimental results. The results show that this novel approach is promising.
Okul Yöneticilerinin Beş Faktör Kişilik Özellikleriyle Çatışma Yönetimi Stili Tercihleri Arasındaki İlişki

Conflict is an inevitable fact of organizational life. In educational organizations, conflicts are also inevitable and likely to occur because the primary input is human and human interactions are so intense in such organizations. This study aimed at investigating the relationship between school administrators’ conflict management style preferences and their personality traits. In this study, the data related to school administrators’ conflict management style preferences was gathered through Rahim’s Organizational Conflict Inventory (ROCI) (1983). In order to reveal school administrators’ personality traits, Five-Factor Personality Inventory (5FKE) which was developed by Somer, Korkmaz and Tatar (2002) was employed. 5FKE and ROCI II were conducted to 89 school principals and 122 deputy principals working at state schools in Kastamonu. In this study, it was found that there are statistically significant correlations between school administrators’ personality traits and their conflict management style preferences.
OPTIMAL TRANSCEIVER DESIGN IN MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT WIRELESS NETWORKS

In the thesis, we first investigate transceiver design for interference management towards maximizing the signal-tointerference-plus-noise ratio (SINR) of the users in multi-cell multiple-input multiple-output (MIMO) wireless networks. Next we study transceiver design for decentralized estimation in wireless sensors networks and demonstrate that precoding helps in realizing in-network signal processing to reduce the complexity and improve the estimation performance. 1. COOPERATIVE BEAMFORMING TECHNIQUES FOR MULTI-CELL MULTI-USER NETWORKS Multi-cell MIMO cooperative beamforming, where a cluster of base stations (BS) cooperate to transmit to different users, is an effective solution for high data rates and multicast video transmission [1]. The BSs can cooperate to transmit their signals such that the inter-cell and intra-cell interference is minimized. Further, when the BSs and users employ multiple antennas, one can design the transmit and receive beamformers to support more number of users. Therefore, the challenge is to develop beamforming schemes that realize the advantages offered by multi-cell MIMO networks [1]. 1.1. Contributions and Methodology We first study transmit and receive beamforming for unicast/multicast multi-cell cooperative transmission with interference among users/user groups. An optimal successive minimum variance beamforming (SMVB) scheme is derived to maximize the sum-rate while successively maintaining orthogonality to the previously scheduled user groups. The proposed beamforming schemes maximize the SINR for each user in case of unicast scenario and maximize the sum SINR of each user group in case of multicast scenario while nulling the interference to the previously scheduled user groups. The main principle of the proposed techniques is to increase the available degrees of freedom by tolerating interference at certain users rather than complete cancellation at every user. These degrees of freedom are exploited to increase the number number of users multiplexed by a factor of number of receive antennas in each scheduling epoch. Thus, enhancing the overall fairness of the system and sum-rate performance compared to the block diagonalization (BD) based Total Power (dB) 2 4 6 8 10 12 14 16 18 20 A ve ra ge V id eo Q ua lit y
Detecting False Intent Amongst Small Cells of Suspects: Single Versus Repeated Interviews

The study adds to the growing research field of true and false intentions. Specifically, we examined the benefit of asking unanticipated questions when interviewing groups of suspects on repeated occasions. Participants were divided into truth tellers and liars and were further divided into groups of three. Truth tellers planned a neutral task. Liars planned a mock crime and additionally prepared a cover-story—thematically similar to the truth tellers' task—to be used if they were apprehended. Participants were intercepted after planning their tasks. In subsequent interviews, participants were asked anticipated questions on their intentions and unanticipated questions on the planning of their intentions. Participants were interviewed once in Experiment 1 (N = 132) and three times in Experiment 2 (N = 123). Truth tellers provided longer and more detailed answers than liars and had higher levels of within-group consistency compared with liars. This was the case for answers to both anticipated and unanticipated questions. No differences between truth tellers and liars were found for between-statement consistency. Repeated interviews had minimal effect on statement length or within-group consistency. The results highlight within-group consistency as an important cue to deceit. However, a number of limitations to the unanticipated questions approach were evident. Copyright © 2014 John Wiley & Sons, Ltd.
Psychological Characteristics and Their Development in Olympic Champions

This study was designed to examine psychological characteristics and their development in Olympic champions. Ten U.S. Olympic champions (winners of 32 Olympic medals) were interviewed, as were one of their coaches ( n = 10), and a parent, guardian, or significant other ( n = 10). A battery of psychological inventories was also administered to the athletes. It was found that the athletes were characterized by: (a) the ability to cope with and control anxiety; (b) confidence; (c) mental toughness/resiliency; (d) sport intelligence; (e) the ability to focus and block out distractions; (f) competitiveness; (g) a hard-work ethic; (h) the ability to set and achieve goals; (i) coachability; (j) high levels of dispositional hope; (k) optimism; and (l) adaptive perfectionism. Results also revealed that a number of individuals and institutions influenced the athletes' psychological development including the community, family, the individual himself or herself, non-sport personnel, sport environment personnel, and the sport process. Coach and family influences were particularly important. Ways in which these sources influenced the athletes were both direct, like teaching or emphasizing certain psychological lessons, and indirect, involving modeling or unintentionally creating certain psychological environments. Psychological characteristic findings verified current sport psychological research on psychological characteristics associated with peak performance (Williams & Krane, 2001). They also suggest that adaptive perfectionism, dispositional hope, and high levels of optimism are new variables to consider. Results are also discussed relative to Bloom's (1985), Côtè's (1999) and Csikzentmihalyi, Rathunde, Whalen, and Wong's (1993) talent development research. Practical implications focus on implementing parenting and coaching practices related to the development of psychological characteristics associated with athletic success.
New Noninvasive Method for Assessment of Left Ventricular Rotation: Speckle Tracking Echocardiography

Background— Left ventricular (LV) torsion is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of LV function. In the present study, we introduce and validate speckle tracking echocardiography (STE) as a method for assessment of LV rotation and torsion. Methods and Results— Apical and basal rotation by STE was measured from short-axis images by automatic frame-to-frame tracking of gray-scale speckle patterns. Rotation was calculated as the average angular displacement of 9 regions relative to the center of a best-fit circle through the same regions. As reference methods we used sonomicrometry in anesthetized dogs during baseline, dobutamine infusion, and apical ischemia, and magnetic resonance imaging (MRI) tagging in healthy humans. In dogs, the mean peak apical rotation was −3.7±1.2° (±SD) and −4.1±1.2°, and basal rotation was 1.9±1.5° and 2.0±1.2° by sonomicrometry and STE, respectively. Rotations by both methods increased (P<0.001) during dobutamine infusion. Apical rotation by both methods decreased during left anterior descending coronary artery occlusion (P<0.007), whereas basal rotation was unchanged. In healthy humans, apical rotation was −11.6±3.8° and −10.9±3.3°, and basal rotation was 4.8±1.7° and 4.6±1.3° by MRI tagging and STE, respectively. Torsion measurement by STE showed good correlation and agreement with sonomicrometry (r=0.94, P<0.001) and MRI (r=0.85, P<0.001). Conclusions— The present study demonstrates that regional LV rotation and torsion can be measured accurately by STE, suggesting a new echocardiographic approach for quantification of LV systolic function.

Meta-analysis and bias in research reviews

This article provides an overview of meta-analysis, a statistical technique that has become common within the health sciences in recent years. In comparison with the traditional narrative review, meta-analysis provides a more effective means of tackling the difficulties that arise in the production of an integrative survey of research on a phenomenon. Even when a solution to a particular methodological problem has not yet been found, meta-analysis often serves a useful function by supplying a framework for characterizing and exploring the nature and extent of the problem. Publication bias is an enduring unsolved problem faced by all methods of research synthesis. Using the framework provided by meta-analysis, it is possible to determine the impact of publication bias on the frequency of spurious conclusions in a discipline. By ascertaining the strength of publication bias in a wide variety of circumstances, it is possible to distinguish those conclusions of a research review in which one can have confidence from those that are less well-founded.
The behaviors, interactions, and perceptions of junior high school students during small-group learning

The study investigated the behaviors, interactions, and perceptions of junior high school students as they worked in structured or unstructured cooperative learning groups on problem-solving, curriculum-based tasks in mathematics, science, and English. Two hundred twenty students in Grade 8 participated in the study, which was conducted across 3 school terms. The students worked in 4-person, gender-balanced, heterogeneous achievement groups. The results show that the children in the structured groups were more cooperative and provided more relevant verbal help and assistance to each other as they worked together in their groups than their peers in the unstructured groups. Furthermore, they had stronger perceptions of small-group work as being enjoyable and providing them with the opportunity to do quality work together.
Use of Novel Boronic Acid Transition State Inhibitors To Probe Substrate Affinity in SHV-Type Extended-Spectrum β-Lactamases

ABSTRACT Boronic acid transition state inhibitors (BATSIs) with R1 side chains of cefotaxime and ceftazidime were assayed against SHV-1, SHV-2, SHV-5, D104K, and D104K G238S β-lactamases. The D104K variant was the most susceptible to inhibition by the ceftazidime BATSI (Ki, 730 ± 80 nM), while the D104K G238S variant was the most susceptible to the cefotaxime BATSI (Ki, 1.1 ± 0.2 μM).
Investigation of the Mixing Efficiency of a Chaotic Micromixer Using Thermal Lens Spectrometry

This work investigates the efficiency of a chaotic micromixer using thermal lens spectrometry. The outlet of the mixing device was connected to a thermal lens detection head integrating the probe beam optical fibers and the sample capillary. The chaotic micromixer consisted of a Y-shaped poly(dimethylsiloxane) (PDMS) microchip in which ribbed herringbone microstructures were etched on the floor of the main channel. Due to the solvent composition dependence of the thermal lens response, the photothermal method was shown to be highly sensitive to nonhomogeneous mixing compared to fluorescence detection. The apparatus was applied to the determination of Fe2+ with 1,10-phenanthroline using flow injection analysis; a limit of detection of 11 μg L−1 of iron was obtained.
Replication Data Management: Needs and Solutions -- An Initial Evaluation of Conceptual Approaches for Integrating Heterogeneous Replication Study Data

[Context] Replication Data Management (RDM) aims at enabling the use of data collections from several itera-tions of an experiment. However, there are several major chal-lenges to RDM from integrating data models and data from em-pirical study infrastructures that were not designed to cooperate, e.g., data model variation of local data sources. [Objective] In this paper we analyze RDM needs and evaluate conceptual RDM approaches to support replication researchers. [Method] We adapted the ATAM evaluation process to (a) analyze RDM use cases and needs of empirical replication study research groups and (b) compare three conceptual approaches to address these RDM needs: central data repositories with a fixed data model, heterogeneous local repositories, and an empirical ecosystem. [Results] While the central and local approaches have major issues that are hard to resolve in practice, the empirical ecosys-tem allows bridging current gaps in RDM from heterogeneous data sources. [Conclusions] The empirical ecosystem approach should be explored in diverse empirical environments.
When Does Retargeting Work ? Timing Information Specificity ∗

Firms can now serve personalized recommendations to consumers who return to their website, based on their earlier browsing history. At the same time, online advertising has greatly advanced in its use of external browsing data across the web to target internet ads appropriately. ‘Dynamic Retargeting’ integrates these two advances by using information from internal browsing data to improve internet advertising on external websites. Consumers who previously visited the firms’ website are shown ads that reflect the specific products they have looked at before on the firm’s own website when surfing the wider web. To examine whether this is more effective than simply showing generic brand ads, we use data from a field experiment conducted by an online travel firm. We find, surprisingly, that increased ad specificity is on average less effective than generic information. We provide evidence that this can be explained by a mismatch between the specificity of this form of advertising and whether a consumer has well-defined product preferences. Only when consumers have well-defined product preferences and are actively engaged in the category are specific ads more effective than generic ads. ∗We thank Havas Digital and particularly Katrin Ribant for access to data from Artemis and Marco Bertini for facilitating the contact to Havas Digital.

Cervical Screening in Canadian First Nation Cree Women

Purpose: Attitudes and beliefs of First Nation Cree women living in a reserve community were explored to gain insights into how cervical screening could be better utilized. Method: Focused ethnography utilizing participant observation and interviews ( n = 8) with participants having experience with cervical screening and/or cancer was conducted. Results: Women did not believe they had adequate information and were resistant to screening because of embarrassment caused by the procedure and fear of cancer, which was viewed as a “death sentence. ” Conclusions: Challenges faced by First Nation Cree women when contemplating cervical screening are presented. Nursing sensitivity is needed to strategize access to cervical screening that is culturally appropriate.
