The Role of Augmented Reality for Experience-Influenced Environments: The Case of Cultural Heritage Tourism in Korea

In cultural heritage sites around the globe, augmented reality (AR) is being utilized as a tool to provide visitors with better experiences while preserving the integrity of the sites. However, little research has examined the impact of AR on customers’ attitudes and behavioral intentions toward the sites. By integrating the post-acceptance model of information systems (IS) continuance, balance theory, and the theory of reasoned action (TRA), we investigate the causal mechanism underlying consumers’ beliefs about AR (perceived advantage, aesthetic experience, and perceived enjoyment) and AR satisfaction in conjunction with the attitudes and behavioral intentions toward the destination. The results show that the perceived advantage and aesthetics of AR influence AR satisfaction. In turn, AR satisfaction affects behavioral intentions toward the heritage destination, indirectly via the attitude toward the destination through AR. Based on these findings, we present theoretical and practical implications as well as suggestions for future research.
Observer design for a class of piecewise linear systems

In this paper we present observer design procedures for a class of bi‐modal piecewise linear systems in both continuous and discrete time. We propose Luenberger‐type observers, and derive sufficient conditions for the observation error dynamics to be globally asymptotically stable, in the case when the system dynamics is continuous over the switching plane. When the dynamics is discontinuous, we derive conditions that guarantee that the relative estimation error with respect to the state of the observed system will be asymptotically small. The presented theory is illustrated with several examples. Copyright © 2007 John Wiley & Sons, Ltd.
of the Annual Meeting of the Cognitive Science Society Title Modeling dilution effects in perceptual load search tasks

A computational model of selective attention has been previously used to provide a concrete and comprehensive account for perceptual load findings in visual search tasks (Neokleous, Koushiou, Avraamides, & Schizas, 2009). Here, the same model was used to simulate findings from an experiment in which perceptual load effects were attributed to distractor dilution (Benoni & Tsal, 2010). By modeling at the neural level the continuous inhibitory interactions that take place among visual stimuli competing for cortical representation, the model reproduced successfully the behavioural pattern of results. The model thus offers a biologically-plausible way to reconcile findings that contradict Perceptual Load theory with those that support it.
Neuronal Expression of Zinc Finger Transcription Factor REST/NRSF/XBR Gene

The identification of a common cis-acting silencer element, a neuron-restrictive silencer element (NRSE), in multiple neuron-specific genes, together with the finding that zinc finger transcription factor REST/NRSF/XBR could confer NRSE-mediated silencing in non-neuronal cells, suggested that REST/NRSF/XBR is a master negative regulator of neurogenesis. Here we show that, although REST/NRSF/XBR expression decreases during neuronal development, it proceeds in the adult nervous system. In situhybridization analysis revealed neuronal expression of rat REST/NRSF/XBR mRNA in adult brain, with the highest levels in the neurons of hippocampus, pons/medulla, and midbrain. The glutamate analog kainic acid increased REST/NRSF/XBR mRNA levels in various hippocampal and cortical neurons in vivo, suggesting that REST/NRSF/XBR has a role in neuronal activity-implied processes. Several alternatively spliced REST/NRSF/XBR mRNAs encoding proteins with nine, five, or four zinc finger motifs are transcribed from REST/NRSF/XBR gene. Two of these transcripts are generated by neuron-specific splicing of a 28-bp-long exon. Rat REST/NRSF/XBR protein isoforms differ in their DNA binding specificities; however, all mediate repression in transient expression assays. Our data suggest that REST/NRSF/XBR is a negative regulator rather than a transcriptional silencer of neuronal gene expression and counteracts with positive regulators to modulate target gene expression quantitatively in different cell types, including neurons.
Schism

We present Schism, a novel workload-aware approach for database partitioning and replication designed to improve scalability of shared-nothing distributed databases. Because distributed transactions are expensive in OLTP settings (a fact we demonstrate through a series of experiments), our partitioner attempts to minimize the number of distributed transactions, while producing balanced partitions. Schism consists of two phases: i) a workload-driven, graph-based replication/partitioning phase and ii) an explanation and validation phase. The first phase creates a graph with a node per tuple (or group of tuples) and edges between nodes accessed by the same transaction, and then uses a graph partitioner to split the graph into k balanced partitions that minimize the number of cross-partition transactions. The second phase exploits machine learning techniques to find a predicate-based explanation of the partitioning strategy (i.e., a set of range predicates that represent the same replication/partitioning scheme produced by the partitioner). The strengths of Schism are: i) independence from the schema layout, ii) effectiveness on n-to-n relations, typical in social network databases, iii) a unified and fine-grained approach to replication and partitioning. We implemented and tested a prototype of Schism on a wide spectrum of test cases, ranging from classical OLTP workloads (e.g., TPC-C and TPC-E), to more complex scenarios derived from social network websites (e.g., Epinions.com), whose schema contains multiple n-to-n relationships, which are known to be hard to partition. Schism consistently outperforms simple partitioning schemes, and in some cases proves superior to the best known manual partitioning, reducing the cost of distributed transactions up to 30%.
Self-organized criticality of a simplified integrate-and-fire neural model on random and small-world network

We consider the criticality for firing structures of a simplified integrate-and-fire neural model on the regular network, small-world network, and random networks. We simplify an integrate-and-fire model suggested by Levina, Herrmann and Geisel (LHG). In our model we set up the synaptic strength as a constant value. We observed the power law behaviors of the probability distribution of the avalanche size and the life time of the avalanche. The critical exponents in the small-world network and the random network were the same as those in the fully connected network. However, in the regular one-dimensional ring, the model does not show the critical behaviors. In the simplified LHG model, the short-cuts are crucial role in the self-organized criticality. The simplified LHG model in three types of networks such as the fully connected network, the small-world network, and random network belong to the same universality class.
Performance in Simulation Is Associated With Clinical Practice Performance in Physical Therapist Students

Introduction. Simulation-based clinical education is often adopted before clinical practice to provide health professional students with practice in a safe environment. The simulated environment is often presumed to replicate clinical practice, but performance in these settings is likely to be different. Simulation may be able to determine student clinical competency before clinical practice. However, there is little research comparing health professional student performance in simulation followed by clinical practice. The aim of the study was to determine whether there was an association between the performance of physical therapist students in simulation and clinical practice and whether aspects of simulation performance could predict subsequent clinical performance. Methods. We measured clinical performance of 148 graduate entry-level master physical therapist students using the Assessment of Physiotherapy Practice (APP) tool (n = 296) at the end of 2 weeks of simulation and subsequent 3 weeks of clinical practice. Assessments were conducted by clinical educators. Data were analyzed using Pearson correlation and multiple regression with backward elimination for exploring predictors of clinical performance. Results. A significant association was found between student performance in simulation and clinical practice (r = .40, P < .001). Two domains of practice of the APP in simulation assessments, “analysis and planning” and “risk assessment,” were found to be predictive of student performance in subsequent clinical practice. Discussion and Conclusion. The association between physical therapist student performance in simulation and clinical practice adds support for simulation assessments being used to determine subsequent clinical practice performance. Educators may consider focusing on learner development in the domains of practice of “analysis and planning” and “risk assessment” in simulation as a way of assisting physical therapist student preparation for clinical practice and facilitating more effective implementation of simulation-based education practices.
The Devaluation of High-Achieving Students as "Streber": Consequences, Processes, and Relations to Personality and the Classroom Context

The current research investigated a phenomenon that has so far received little attention: the stigmatization of students who are characterized by strong academic orientation. The research question was whether certain personality traits – beyond academic achievement – are typical of students who are labeled “Streber” (a nerd with respect to academic achievement; German origin) and of those who tend to label their peers Streber. Apart from individual characteristics, we also examined the impact of the classroom context. In the first study (N = 317), eighth grade students nominated classmates whom they perceived to be a prototypical Streber and provided self-ratings on how often they had labeled others Streber. In the second study (N = 358), using a round robin design, we had eighth grade students rating each of their classmates to what extent they perceive them as Streber. Results showed that being labeled was associated with high academic achievement, but also with introversion and conscientiousness even when controlling for academic achievement. Labeling others was connected to extraversion, low conscientiousness, and low agreeableness. Furthermore, we found that the stigmatization was stronger in high-achieving than in low-achieving classes. Additionally, average classroom achievement moderated the relationship between individual factors and stigmatization in a way that the relationships were particularly strong in highachieving classes. Results are discussed with respect to personality traits as potential risk factors of peer stigmatization and the impact of the classroom context.
Peaceful Nuclear Tests, Eco-friendly Reactors, and the Vantage Point of Tamasha

The article analyzes the role of the documentary form in building pronuclear narratives around the Indian nuclear project. It situates the nuclear films made by two state institutions, Films Division of India (Films Division) and Vigyan Prasar, as part of a network of expert statements, documentary assertions, and state violence that bring into being a pronuclear reality. Through the insights gained from my practice-based enquiry, which led to the production and circulation of a film titled Nuclear Hallucinations, I argue that the certainty of the pronouncements of such documentaries can be unsettled by approaching them as a tamasha. I rely on the multiple connotations of the word tamasha in the South Asian context and its ability to turn solemn assertions into a matter of entertainment or a joke. This vantage point of tamasha vis-à-vis the Indian nuclear project builds upon the strategies of antinuclear documentaries that resist the epistemological violence of pronuclear assertions. In this article, I explore the role of comic modes and irony in forming sites of tamasha to create trouble within the narratives that position nonviolent antinuclear protestors as “antinational” elements. The article also expands on how the point of view of tamasha can engender new solidarities, which can resist the violence of the Indian nuclear project by forming new configurations of possibilities.
Cannon–Thurston maps for pared manifolds of bounded geometry

Let N h ∈, H(M, P) be a hyperbolic structure of bounded geometry on a pared manifold such that each component of ∂ 0 M = ∂M - P is incompressible. We show that the limit set of N h is locally connected by constructing a natural Cannon-Thurston map. This provides a unified treatment, an alternate proof and a generalization of results due to Cannon and Thurston, Minsky, Bowditch, Klarreich and the author.
Analytic Expressions for Rate and CV of a Type I Neuron Driven by White Gaussian Noise

We study the one-dimensional normal form of a saddle-node system under the influence of additive gaussian white noise and a static bias current input parameter, a model that can be looked upon as the simplest version of a type I neuron with stochastic input. This is in contrast with the numerous studies devoted to the noise-driven leaky integrate-and-fire neuron. We focus on the firing rate and coefficient of variation (CV) of the interspike interval density, for which scaling relations with respect to the input parameter and noise intensity are derived. Quadrature formulas for rate and CV are numerically evaluated and compared to numerical simulations of the system and to various approximation formulas obtained in different limiting cases of the model. We also show that caution must be used to extend these results to the neuron model with multiplicative gaussian white noise. The correspondence between the first passage time statistics for the saddle-node model and the neuron model is obtained only in the Stratonovich interpretation of the stochastic neuron model, while previous results have focused only on the Ito interpretation. The correct Stratonovich interpretation yields CVs that are still relatively high, although smaller than in the Ito interpretation; it also produces certain qualitative differences, especially at larger noise intensities. Our analysis provides useful relations for assessing the distance to threshold and the level of synaptic noise in real type I neurons from their firing statistics. We also briefly discuss the effect of finite boundaries (finite values of threshold and reset) on the firing statistics.
Generativity in College Students: Comparing and Explaining the Impact of Mentoring

Preparing college students to be active contributors to the next generation is an important function of higher education. This assumption about generativity forms a cornerstone in this mixed methods study that examined generativity levels among 273 college students at a 4-year public university. MANCOVA results indicated that college students who mentor demonstrated significantly higher generativity than non-mentoring students. Interviews with 9 mentoring students revealed that, although a “seed of generativity” may have already been planted, their mentoring experience served as a “lab” for learning how to be generative. The integrated findings offer important contributions relative to leadership and social responsibility.
A vector space search engine for Web services

As Web services increasingly become important in distributed computing, some of the flaws and limitations of this technology become more and more obvious. One of this flaws is the discovery of Web services through common methods. Research has been pursued in the field of "semantic Web services". This research is driven by the idea, to describe the functionality of Web services as accurately as possible and to create programs automatically out of already existing Web services. In this paper we discuss a new method for discovery and analysis of Web services. Our approach uses a vector space search engine to index descriptions of already composed services. Rather than generating or automatically composing applications, this approach provides developers with a valuable utility to browse repositories based on already existing information. Furthermore, we propose some additional modifications to extract the maximum amount of semantics from existing service definition repositories.
Who Framed the Steroid Issue in Baseball?: A Study of the Frame-Source Relationship in Traditional and New Media

Abstract: This study explored sourcing patterns and the relationship between frames and sources in the coverage of the steroid issue in baseball through a content analysis of traditional and new media. Contrary to extant research about sourcing in the media, this study found that the media did not use officials as their most frequent sources but relied primarily on baseball players to talk about steroids. Beyond players, however, the media did use governmental and sports officials to provide authoritativeness to their stories. The frame-source relationship showed the strongest correlation between official sources and the policy frame. Officials also tended to be featured in stories dealing with business actors. Finally, the blogs in this sample differed from traditional media in their use of dominant frames and sources.
Paternalistic Leadership as a Reflection of Collectivism Culture

This research tries to complete transformational leadership and transactional leadership that is still controversial in some organizations. Therefore, paternalistic leadership becomes a model of leadership that is able to mediate the difference. In addition, to prove whether paternalistic leadership is still considered relevant in Indonesian environment to resolve different personalities. Paternalistic leadership is a consists of three leadership styles: authoritarian leadership, benevolent leadership, and moral leadership. The population in this study were all of the police officer at the Police Academy which amounted to 534 police officer. Samples taken using purposive judgment sampling method amounted to 179 police officer. Analytical techniques using AMOS 20.00 program. The result of research shows that collectivism culture has a positive influence on paternalistic leadership, collectivism culture can enhance paternalistic leadership. Paternalistic leadership has a positive influence on police officer engagement, paternalistic leadership can increase police officer engagement. Police officer engagement positively influence on police officer performance, police officer engagement can improve police officer performance. However, paternalistic leadership has no effect on police officer performance directly. Paternalistic leadership can enhance police officer performance through police officer engagement. Keywords— Collectivism Culture, Paternalistic Leadership, Police Officer Engagement, Police Officer Performance
Activity Monitor Intervention to Promote Physical Activity of Physicians-In-Training: Randomized Controlled Trial

Background Physicians are expected to serve as role models for healthy lifestyles, but long work hours reduce time for healthy behaviors. A hospital-based physical activity intervention could improve physician health and increase counseling about exercise. Methods We conducted a two-phase intervention among 104 medical residents at a large hospital in Boston, Massachusetts. Phase 1 was a 6-week randomized controlled trial comparing daily steps of residents assigned to an activity monitor displaying feedback about steps and energy consumed (intervention) or to a blinded monitor (control). Phase 2 immediately followed and was a 6-week non-randomized team steps competition in which all participants wore monitors with feedback. Phase 1 outcomes were: 1) median steps/day and 2) proportion of days activity monitor worn. The Phase 2 outcome was mean steps/day on days monitor worn (≥500 steps/day). Physiologic measurements were collected at baseline and study end. Median steps/day were compared using Wilcoxon rank-sum tests. Mean steps were compared using repeated measures regression analyses. Results In Phase 1, intervention and control groups had similar activity (6369 vs. 6063 steps/day, p = 0.16) and compliance with wearing the monitor (77% vs. 77% of days, p = 0.73). In Phase 2 (team competition), residents recorded more steps/day than during Phase 1 (Control: 7,971 vs. 7,567, p = 0.002; Intervention: 7,832 vs. 7,739, p = 0.13). Mean compliance with wearing the activity monitor decreased for both groups during Phase 2 compared to Phase 1 (60% vs. 77%, p<0.001). Mean systolic blood pressure decreased (p = 0.004) and HDL cholesterol increased (p<0.001) among all participants at end of study compared to baseline. Conclusions Although the activity monitor intervention did not have a major impact on activity or health, the high participation rates of busy residents and modest changes in steps, blood pressure, and HDL suggest that more intensive hospital-based wellness programs have potential for promoting healthier lifestyles among physicians.

A Tale of Two Entangled Instabilities - The Dual Role of δ-O in HgBa2Can-1CunO2(n+1)+δ

Low-energy instabilities in the hole doped cuprates include, besides short range antiferromagnetic fluctuations and superconductivity, also ubiquitous translational and rotational symmetry breakings. The overwhelming majority of interpretations of these possibly related properties rely on mappings onto three bands spanned by the three atomic orbitals Cu3d(x2-y2)(sigma), O2px(sigma), and O2py(sigma), these three local orbitals spanning the Zhang-Rice band (ZRB), the lower Hubbard bands (LHB) and the upper Hubbard bands (UHB), respectively. Here we demonstrate by means of supercell Density Functional Theory (DFT) (a) how oxygen intercalation affects the structures of the buffer layers, and (b) how the attenuated crystal field pulls two additional oxygen bands in the CuO2 plane to the Fermi level. The self-consistent changes in electronic structure reflected in the corresponding changes in external potential comprise formal properties of the Hohenberg-Kohn theorems. Validation of present days' approximate exchange-correlation potentials to capture these qualitative effects by means of supercell DFT is made by comparing computed doping dependent structural shifts to corresponding experimentally observed correlations. The simplest generalization of Bardeen-Cooper-Schrieffer (BCS) theory is offered to articulate high critical temperature superconductivity (HTS) from a normal state where crystal field causes states related to two non-hybridizing bands to coalesce at EF.
