Exploring Scientic Discovery with Large-Scale Parallel Scripting

Scientists and the organizations that fund scientific research frequently face difficult questions about how to allocate scarce resources. Should they pursue safe avenues of investigation that incrementally extend current knowledge? Or should they pursue ideas that are far off the beaten track, which are less likely to bear fruit, but more likely to provide revolutionary insights? One group at the University of Chicago [4] is trying to provide some insight by developing a model of scientific discovery and exploring what parameters match real world data, and what parameters maximize knowledge production. This demo will describe the methods we used to take a a sequential simulation of scientific discovery and build an optimization algorithm that scales to thousands of cores.
Techniques and paradoxes in performing performance measurements: concluding reflections

ABSTRACT Performance measurement has an implicit performance theory embedded within its practice; performance measurement perforce performs. Performance measurement has a performative effect on performance. Drawing together and building on the various empirical observations from the preceding papers in this collection, this concluding paper firstly examines the circumstances in which performance measurement performs, that is, when it produces ‘authentic’ performance improvements, compared to when performance measurements misfire. The paper secondly explores several paradoxes of performance measurement – such that performance measurement measures only part of the performance it seeks to be performative on, incentives to perform incentivise poor performance and so on. These paradoxes, contradictions and ironies must be apprehended and appreciated in discovering, discerning and deciphering the diverse dynamics of measuring performance. They also demonstrate that analysing and working with performance measurement requires a perspective that eschews absolutes and clear directions, and embraces the uneasy and potentially destabilising tension of Escher’s performative art.

Influence of Head Nurses' Ethical Leadership on Job Satisfaction among Staff Nurses: Mediating Effect of Affective Commitment

Purpose: This study was conducted to identify the mediating effect of affective commitment on the relationship between ethical leadership and job satisfaction. Methods: Participants were 216 nurses drawn from three general hospitals in C city. Data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and multiple regression. Results: The findings from multiple regression were as follows. First, people orientation, ethical guidance of ethical leadership factors showed significant positive effects on affective commitment. Second, people orientation, ethical guidance of ethical leadership factors showed significant positive effects on job satisfaction. Finally, when ethical leadership factors and affective commitment were entered into the regression model at the same time, ethical leadership factors showed no significant effects on job satisfaction, however, affective commitment showed a significant effect and so affective commitment had a mediating effect between ethical leadership and job satisfaction. Conclusion: Results of this study indicate that affective commitment with an effect on the relationship between ethical leadership and job satisfaction plays a full mediating role. Thus, developing ethical leadership training programs for head nurses would likely increase the affective commitment and job satisfaction of staff nurses

Multidigit Movement Synergies of the Human Hand in an Unconstrained Haptic Exploration Task

Although the human hand has a complex structure with many individual degrees of freedom, joint movements are correlated. Studies involving simple tasks (grasping) or skilled tasks (typing or finger spelling) have shown that a small number of combined joint motions (i.e., synergies) can account for most of the variance in observed hand postures. However, those paradigms evoked a limited set of hand postures and as such the reported correlation patterns of joint motions may be task-specific. Here, we used an unconstrained haptic exploration task to evoke a set of hand postures that is representative of most naturalistic postures during object manipulation. Principal component analysis on this set revealed that the first seven principal components capture >90% of the observed variance in hand postures. Further, we identified nine eigenvectors (or synergies) that are remarkably similar across multiple subjects and across manipulations of different sets of objects within a subject. We then determined that these synergies are used broadly by showing that they account for the changes in hand postures during other tasks. These include hand motions such as reach and grasp of objects that vary in width, curvature and angle, and skilled motions such as precision pinch. Our results demonstrate that the synergies reported here generalize across tasks, and suggest that they represent basic building blocks underlying natural human hand motions.
Reducing Students’ Cognitive Load Using Smartphones

The variety, number, and access to educational opportunities has exploded as more traditional institutions of higher education have expanded their educational catalogs and degree-seeking programs, both in-seat and online. As such, many adults, are either returning to higher education to continue their education, or entering higher education for the first time after a long absence from formal education. As educational opportunities have expanded, so too has the problem of student attrition. The factors that cause students to leave their education programs and courses prior to completing them are hotly debated, but there appear to be some consistent factors for in-seat and online students who are adult learners.
The association between the hostile-world scenario, perceived control, and emotional distress among gay men and lesbians

ABSTRACT We examined the moderating role perceived control plays in the relationship between hostile-world scenarios unique to gay men and lesbians and emotional distress. A convenience sample of Israeli gay (n = 56) and lesbian (n = 42) participants who were recruited online through snowball sampling completed questionnaires examining emotional distress, perceived control, and hostile-world themes unique to the gay and lesbian communities. The hostile-world scenario was significantly and positively associated with emotional distress. Additionally, only among lesbians, perceived control moderated the relationship between the hostile-world scenario and emotional distress. Perceived control may provide a protective factor against the effect of hostile-world scenarios on emotional distress among lesbians.
A Novel Protocol for Privacy Preserving Banking Computations using Arithmetic Cryptography

The expansion of internet escalated banking to a new level and has raised tremendous opportunities of joint transactions in which multiple banks cooperatively conduct some computation. Such computations use confidential data of the involved banks to compute the result. As the concerned data is private for the owning organization, its security is prime concern. Privacy preservation concern rises as no party can be trusted enough to know all the inputs of computation. In this paper we have proposed a scalable and efficient protocol to perform secure multi-party computations on encrypted data. The process involves encrypting data in a manner that it does not affect the result of the computation. Virtual parties are created by all organizations and encrypted data is distributed among them. Modifier tokens are generated along encryption which are assigned to virtual parties, and finally used in the computation. The computation function uses the acquired data and modifier tokens to compute result. As the data involved in computation was encrypted, without revealing the data right result can be computed and privacy of the parties is maintained. The protocol is highly efficient in conducting banking computations. We have analyzed the security and complexity of protocol and shown how zero hacking security can be achieved. Also we have analyzed the performance through various tests.
Limited-area modelling of stratocumulus over South-Eastern Pacific

Abstract. This paper presents application of the Weather Research and Forecasting (WRF) model to limited-area modeling of atmospheric processes over the subtropical south-eastern Pacific, with the emphasis on the stratocumulus-topped boundary layer. The simulations cover a domain from the VAMOS (Variability of the American Monsoon Systems) Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) field project conducted in the subtropical south-eastern Pacific in October and November 2008. We focus on a day where the UK's BAe-146 research aircraft encountered Pockets of Open Cells (POCs) at the very western edge of its flight track, rather than on the entire campaign as investigated in previous limited-area modeling studies. Model results are compared to aircraft observations with the main conclusion that the simulated stratocumulus-topped boundary layer is significantly too shallow. This appears to be a combination of an already too shallow boundary layer in the dataset used to provide initial and lateral boundary conditions, and the inability of the WRF model to increase the boundary-layer height. Several sensitivity simulations, applying different subgrid-scale parameterizations available in the model, a larger computational domain and longer simulations, as well as a different dataset providing initial and lateral boundary conditions were all tried to improve the simulation. These changes appeared to have a rather small effect on the results. The model does simulate the formation of mesoscale cloud-free regions that one might consider similar to Pockets of Open Cells observed in nature. However, formation of these regions does not seem to be related to drizzle-induced transition from open- to closed-cell circulations as simulated by LES models. Instead, the cloud-free regions appear to result from mesoscale variations of the lower-tropspheric vertical velocity. Areas of negative vertical velocity with minima (a few cm s−1) near the boundary layer top seem to induce direct evaporation of the cloud layer. It remains to be seen in LES studies whether the mechanism seen in the model is realistic or if it is simply an artifact of interactions between resolved and parameterized processes.
Some Results on Anonymity in Hybrid Encryption

Anonymity(key-privacy) as well as security(data-privacy) are all important features in public-key encryption applications. In this paper two new and general concepts, named “relevant anonymity” and “relevant security”, are defined. Based-upon these concepts some general results on anonymity in public-key encryption are proved, which fall in three categories. The first results are two general relationships between anonymity and security; the second are a sufficient and necessary condition for chosen-plaintext anonymity in Fujisaki-Okamoto hybrid construction and a sufficient condition for its chosen-ciphertext anonymity; the third is a sufficient condition for chosen-ciphertext anonymity in Okamoto-Pointcheval hybrid construction (REACT). All these conditions are also easy-to-use criteria in practice. By examples such general consequences are applied to some specific schemes and as a result anonymity of some well-known schemes are re-established in a simpler way. Furthermore, NISSIE scheme PSEC-/1/2/3’s chosen-ciphertext anonymity are proved.
A secured energy efficient route-driven ECDH scheme for heterogeneous sensor networks

Most of the research work has shown that homogeneous ad hoc networks have poor performance, connectivity and scalability. Heterogeneous sensor network (HSN) consists of physically different types of sensor nodes. The feasibility of implementing Elliptic Curve Cryptography (ECC) in HSN is simulated in this approach. It utilizes Elliptic Curve Diffie-Hellman (ECDH) by using pseudo-random polynomial function to design an energy efficient key management scheme for HSN. The work implements grid-based coordinate routing driven scheme in the proposed method. This routing driven scheme is highly adaptable for public key management scheme for HSN and compares the energy and throughput efficiency available in the network over time for different grid sizes. A test area network is divided into square-shaped grids of specified lengths. Highly charged battery powered sensor nodes are randomly placed in the area with a fixed source nodes and sink nodes. The source node starts flooding the sensor network with every coordinator node joining in the routing. This entire process continues until the network is partitioned and the connectivity between the source and the sink nodes is lost. The proposed method is compared with the existing routing techniques like AODV and DSR. Here, the comparison is done with respect to energy conservation, end to end delay and throughput. The proposed routing driven method improves the quality of service of HSN's and extends it network lifetime based on the elected coordinator nodes and the size of the grid area.
Value Implications of Relative Investments in Information Technology

In this study, we investigate how divergence from the industry level of investment in information technology (IT) affects firm value. Theoretical arguments suggest that greater investment in IT relative to industry peers may positively affect firm value and that smaller relative investment may negatively affect firm value, but these arguments have not been empirically tested. We perform our analysis using data obtained from disclosures of IT spending in preparation for the year 2000. During this period, firms had options to replace legacy applications with enterprise applications that could improve internal business processes and enhance external coordination with other members of the industry value chain. We document a positive relation between firm value and the amount by which a firm’s IT spending in preparation for the year 2000 exceeded the industry median level and a negative relation between firm value and the amount by which the firm’s IT spending lagged behind the industry median level. We also find a positive relation between firm value and the industry median level of IT spending, consistent with value creation through the development of IT infrastructure for the industry value chain.
An out-of-character approach to emergent game narratives

This paper is a first step toward the exploration and further development of the narrative possibilities offered by emergent games. First, we present the five characteristics of emergent narratives that we believe to be fundamental: coherence, agency, possibility space, uncertainty and coauthoring. Then, we investigate the presence of these characteristics in various academic experiments. Finally, we describe a novel approach that provides players with high level actions that they can perform in order to manipulate the story in real time.
Medical question answering: translating medical questions into sparql queries

Designing question answering systems requires efficient and deep analysis of natural language questions. A key process for this task is to translate the semantic relations expressed in the question into a machine-readable representation. In this paper we tackle question analysis in the medical field. More precisely, we study how to translate a natural language question into a machine-readable representation. The underlying transformation process requires determining three key points: (i) What are the main characteristics of medical questions? (ii) Which methods are the most fitted for the extraction of these characteristics? and (iii) how to translate the extracted information into a machine-understandable representation? We present a complete question analysis approach including medical entity recognition, semantic relation extraction and automatic translation to SPARQL queries. Our study supports the fact that SPARQL can represent a wide range of natural language questions in a question-answering perspective. Experiments on a corpus of real questions show that we obtain encouraging results in medical entity recognition and relation extraction. The obtained results also show that the output SPARQL queries correctly represent more than 60% of the original questions.
Speculative Parallel Evaluation Of Classification Trees On GPGPU Compute Engines

We examine the problem of optimizing classification tree evaluation for on-line and real-time applications by using GPUs. Looking at trees with continuous attributes often used in image segmentation, we first put the existing algorithms for serial and data-parallel evaluation on solid footings. We then introduce a speculative parallel algorithm designed for single instruction, multiple data (SIMD) architectures commonly found in GPUs. A theoretical analysis shows how the run times of data and speculative decompositions compare assuming independent processors. To compare the algorithms in the SIMD environment, we implement both on a CUDA 2.0 architecture machine and compare timings to a serial CPU implementation. Various optimizations and their effects are discussed, and results are given for all algorithms. Our specific tests show a speculative algorithm improves run time by 25% compared to a data decomposition.
Binocular coordination of eye movements – Hering’s Law of equal innervation or uniocular control?

The neurophysiological basis for binocular control of eye movements in primates has been characterized by a scientific controversy that has its origin in the historical conflict of Hering and Helmholtz in the 19th century. This review focuses on two hypotheses, linked to that conflict, that seek to account for binocular coordination – Hering’s Law vs. uniocular control of each eye. In an effort to manage the length of the review, the focus is on extracellular single‐unit studies of premotor eye movement cells and extraocular motoneurons. In the latter half of the 20th century, these studies provided a wealth of neurophysiological data pertaining to the control of vergence and conjugate eye movements. The data were initially supportive of Hering’s Law. More recent data, however, have provided support for uniocular control of each eye consistent with Helmholtz’s original idea. The controversy is far from resolved. New anatomical descriptions of the disparate inputs to multiply and singly innervated extraocular muscle fibers challenge the concept of a ‘final common pathway’ as they suggest there may be separate groups of motoneurons involved in vergence and conjugate control of eye position. These data provide a new challenge for interpretation of uniocular premotor control networks and how they cooperate to produce coordinated eye movements.

Instructions for use Title [ 18 F ] fluoromisonidazole and a New PET System With Semiconductor Detectors and a Depth of Interaction System for Intensity Modulated Radiation Therapy for Nasopharyngeal Cancer

Purpose: The impact of a new type of positron emission tomography with semiconductor detectors (New PET) on an 18F-fluoromisonidazole (FMISO)-guided intensity-modulated radiation therapy (IMRT) plan was investigated by comparing the plan with the use of a state-of-the-art PET/computed tomography system (PET/CT) in nasopharyngeal cancer (NPC) patients. Methods and Materials: Twenty-four patients with non-NPC malignant tumors (control group) and 16 patients with NPC were subjected to FMISO-PET. The threshold of the tumor-to-muscle (T/M) ratio in each PET scan was calculated. The hypoxic volume within the gross tumor volume was determined using each PET (NewPETGTVh and PET/CTGTVh, respectively). Dose-escalation IMRT plans prescribing 84Gy to each GTVh were carried out. Results: The threshold of the T/M ratio was calculated to be 1.35 for New PET and 1.23 for PET/CT. The mean volume of NewPETGTVh was significantly smaller than that of PET/CTGTVh (1.5±1.6cc vs. 4.7±4.6cc, respectively, P=0.0020). The dose-escalation IMRT plans using New PET were superior in dose distribution to those using PET/CT. Dose escalation was possible in all 10 New PET-guided plans but not in one PET/CT-guided plan, because the threshold dose to the brainstem was exceeded. Conclusion: New PET was suggested to be useful for accurate dose escalation in FMISO-guided IMRT for patients with NPC.
