Learning to Manage Innovation and Change through Organizational and People Dynamics Simulations

: The key to the approach illustrated in this paper is the use of Information Technology to model the dynamics of social contexts (including individual behaviors, group dynamics and cultural factors) to stimulate learning in complex domains such as innovation and change management. Adopting a ‘learning by doing’ philosophy, experiences conducted over the last years have demonstrated that it is possible to stimulate learning by enabling groups of managers to experience the challenge (and the frustration - let's not forget that more than 70% of large change/innovation projects fail! ) of being responsible for the implementation of major change projects in realistically simulated organizational contexts. The resulting advanced simulations have shown to provide a powerful alternative approach to complement, substitute and extend traditional teaching approaches in a critical field such as change and innovation management, offering an opportunity to apply models from social and organizational dynamics to design advanced 'Experiential Adventures' with significant pedagogical effectiveness, to the extent that such simulations have been successfully adopted by universities such as Stanford, MIT, or Wharton to replace or complement their traditional approach to teach change to management students and executives. This article first provides the motivation for applying new educational approaches to address critical subjects such as change management. It then illustrates the concept of social simulations through an extensively validated example, the EIS Simulation, and finally discusses the applicability of the presented eLearning approach to the effective development of competencies of managers, but also of other target learners, such as engineers, citizens, or young adults, for which the extended exposure to modern video games generates a particularly high receptivity to this computer-enhanced approach to learning about effective interaction in social contexts.
Pragmatic force modifiers in ELF academic discussions

Abstract This article reports an empirical study of the functions of pragmatic force modifiers (PFMs) in English as a lingua franca (ELF) use in academic discussions. PFMs are pervasive in spoken language but have been under-researched in contexts of multinational and polylogic communications. The aim of this study is to investigate how different event types affect the use of PFMs in ELF discourse. PFMs used in the academic discussions are identified and their distributions in different event types of the Corpus of English as a Lingua Franca in Academic Settings are explored. The functions of the PFMs in different event types are then examined and discussed. Results reveal that ELF speakers use well-specified PFMs to fulfill appropriate functions in different event types under the genre of academic discussions, i.e. flagging suggestions and downplaying criticism in conference discussions, marking elicitation and tailoring explanation in lecture discussions, expressing commitment and certainty in doctoral defense discussions, and projecting personal opinions in seminar discussions. It is argued that although PFMs are linguistic devices commonly used in academic discussions, their functions are sensitive to specific event types. At least, the present study concludes that these context-sensitive uses are clearly in evidence in ELF speech.
The Insignificance of P-R drag in detectable extrasolar planetesimal belts

This paper considers a simple model in which dust produced in a planetesimal belt migrates in toward the star due to P-R drag suffering destructive collisions with other dust grains on the way. Assuming the dust is all of the same size, the resulting surface density distribution can be derived analytically and depends only on the parameter η0 = 5000τeff (r0) √ M� /r0/β; this parameter can be determined observationally with the hypothesis that β = 0.5. For massive belts in which η0 � 1 dust is confined to the planetesimal belt, while the surface density of more tenuous belts, in which η0 � 1, is constant with distance from the star. The emission spectrum of dust from planetesimal belts at different distances from different mass stars shows that the dust belts which have been detected to date should have η0 � 1; dust belts with η0 � 1 are hard to detect as they are much fainter than the stellar photosphere. This is confirmed for a sample of 37 debris disk candidates for which η0 was determined to be >10. This means that these disks are so massive that mutual collisions prevent dust from reaching the inner regions of these systems and P-R drag can be ignored when studying their dynamics. Models for the formation of structure in debris disks by the trapping of particles into planetary resonances by P-R drag should be reconsidered. However, since collisions do not halt 100% of the dust, this means that in the absence of planetary companions debris disk systems should be populated by small quantities of hot dust which may be detectable in the mid-IR. Even in disks with η0 � 1 the temperature of dust emission is shown to be a reliable tracer of the planetesimal distribution meaning that inner holes in the dust distribution imply a lack of colliding planetesimals in the inner regions.
ec 2 00 1 Evolution of Isolated Neutron Stars

Abstract. In this paper we briefly review our recent results on evolution and properties of isolated neutron stars (INSs) in the Galaxy. As the first step we discuss stochastic period evolution of INSs. We briefly discuss how an INS’s spin period evolves under influence of interaction with turbulized interstellar medium. To investigate statistical properties of the INS population we calculate a census of INSs in our Galaxy. We infer a lower bound for the mean kick velocity of NSs, < V >∼(200-300) kms. The same conclusion is reached for both a constant magnetic field (B ∼ 10 G) and for a magnetic field decaying exponentially with a timescale ∼ 10 yr. These results, moreover, constrain the fraction of low velocity NSs, which could have escaped pulsar statistics, to ∼few percents. Then we show that for exponential field decay the range of minimum value of magnetic moment, μb: ∼ 10 29.5 ≥ μb ≥ 10 28 Gcm, and the characteristic decay time, td: ∼ 10 8 ≥ td ≥ 10 7 yrs, can be excluded assuming the standard initial magnetic momentum, μ0 = 10 30 Gcm, if accreting INSs are observed. For these parameters an INS would never reach the stage of accretion from the interstellar medium even for a low space velocity of the star and high density of the ambient plasma. The range of excluded parameters increases for lower values of μ0. It is shown that old accreting INSs become more abundant than young cooling INSs at X-ray fluxes below ∼ 10 erg cm s. We can predict that about one accreting INS per square degree should be observed at the Chandra and Newton flux limits of ∼ 10 erg cm s. The weak ROSAT sources, associated with INSs, can be young cooling objects, if the NSs birth rate in the solar vicinity during the last ∼ 10 yr was much higher than inferred from radiopulsar observations.
Latent visual context analysis for image re-ranking

Currently Web image search is mostly implemented as text retrieval based on the textual information extracted from the Web page associated with the image. Since the text in the Web page may not match with the image content, image search re-ranking is preferable to refine the text-based search results. In this paper, we propose a novel scheme of latent visual context analysis (LVCA) for image re-ranking. The latent visual context is explored in both latent semantic context and visual link graphs. We argue that the image significance is determined by its contained visual word context, which is analyzed through Latent Semantic Analysis (LSA) and visual word link graph. With the visual word context information, the image context is explored by analysis of image link graph and the significance value for each image can be inferred by VisualRank. In both visual word link graph and image link graph, latent-layer will be incorporated to effectively discover the visual context. We validate our approach on text-query based search results returned by Google Image. Experimental results show improvement of both accuracy and efficiency of our method over the state-of-the-art VisualRank algorithm.
ASIC Design of Reversible Multiplier Circuit

Reversible logic is very much in demand for the future computing technologies as they are known to produce low power dissipation having its applications in Low Power CMOS, Quantum Computing, Nanotechnology, and Optical Computing. Adders and multipliers are fundamental building blocks in many computational units. In this paper we have presented and implemented reversible Wallace signed multiplier circuit in ASIC through modified Baugh-Wooley approach using standard reversible logic gates/cells, based on complementary pass-transistor logic and have been validated with simulations, a layout vs. Schematic check, and a design rule check. It is proved that the proposed multiplier is better and optimized, compared to its existing counterparts with respect to the number of gates, constant inputs, garbage outputs, hardware complexity, and number of transistors required. It has also been shown in Cadence's tools that the reversible multiplier outperform the irreversible multiplier in terms of power dissipation.
Framework for smart city applications based on participatory sensing

Smart cities offer services to their inhabitants which make everyday life easier beyond providing a feedback channel to the city administration. For instance, a live timetable service for public transportation or real-time traffic jam notification can increase the efficiency of travel planning substantially. Traditionally, the implementation of these smart city services require the deployment of some costly sensing and tracking infrastructure. As an alternative, the crowd of inhabitants can be involved in data collection via their mobile devices. This emerging paradigm is called mobile crowd-sensing or participatory sensing. In this paper, we present our generic framework built upon XMPP (Extensible Messaging and Presence Protocol) for mobile participatory sensing based smart city applications. After giving a short description of this framework we show three use-case smart city application scenarios, namely a live transit feed service, a soccer intelligence agency service and a smart campus application, which are currently under development on top of our framework.
Weighted PageRank using the Rank Improvement

Information available on the WWW, users’ get easily lost in rich hyper structure. It has become increasingly necessary for user’s to utilize automated tool in order to find, extract, filter and evaluate the desired information and resources. Modern Information Retrieval System matches the term of a user with documents in their index and returns a large number of documents of Web pages generally in the form of ranked list. It becomes almost impractical at the user end to examine every return document, thus the need to look for some result optimization. In this paper, finding the content of the web and retrieving the users’ interest and need from their behaviour has become important . Web mining is used to cauterized user and pages by analyzing the user’s behaviour, content of pages, order of the URLs, Two page ranking algorithms, HITS and PageRank. The Weighted Page Rank algorithm (WPR), takes into account the importance of both inlinks and the outlinks of the pages and distributes rank scores based on the popularity of the pages. In this paper we have the relevancy values for the query produced by Page Rank and WPR using different page set and finally search result list is reranked by updating the existing page rank values of a page. The proposed work result WPR performs better than Page Rank and reduced search time and important pages are tending to move upwards in the result list.

The two factors represent the multiple perspective taking construct as defined in this
Coarse-grained Candidate Generation and Fine-grained Re-ranking for Chinese Abbreviation Prediction

Correctly predicting abbreviations given the full forms is important in many natural language processing systems. In this paper we propose a two-stage method to find the corresponding abbreviation given its full form. We first use the contextual information given a large corpus to get abbreviation candidates for each full form and get a coarse-grained ranking through graph random walk. This coarse-grained rank list fixes the search space inside the top-ranked candidates. Then we use a similarity sensitive re-ranking strategy which can utilize the features of the candidates to give a fine-grained re-ranking and select the final result. Our method achieves good results and outperforms the state-ofthe-art systems. One advantage of our method is that it only needs weak supervision and can get competitive results with fewer training data. The candidate generation and coarse-grained ranking is totally unsupervised. The re-ranking phase can use a very small amount of training data to get a reasonably good result.
Characterization and Expression of the Lucina pectinata Oxygen and Sulfide Binding Hemoglobin Genes

The clam Lucina pectinata lives in sulfide-rich muds and houses intracellular symbiotic bacteria that need to be supplied with hydrogen sulfide and oxygen. This clam possesses three hemoglobins: hemoglobin I (HbI), a sulfide-reactive protein, and hemoglobin II (HbII) and III (HbIII), which are oxygen-reactive. We characterized the complete gene sequence and promoter regions for the oxygen reactive hemoglobins and the partial structure and promoters of the HbI gene from Lucina pectinata. We show that HbI has two mRNA variants, where the 5’end had either a sequence of 96 bp (long variant) or 37 bp (short variant). The gene structure of the oxygen reactive Hbs is defined by having 4-exons/3-introns with conservation of intron location at B12.2 and G7.0 and the presence of pre-coding introns, while the partial gene structure of HbI has the same intron conservation but appears to have a 5-exon/ 4-intron structure. A search for putative transcription factor binding sites (TFBSs) was done with the promoters for HbII, HbIII, HbI short and HbI long. The HbII, HbIII and HbI long promoters showed similar predicted TFBSs. We also characterized MITE-like elements in the HbI and HbII gene promoters and intronic regions that are similar to sequences found in other mollusk genomes. The gene expression levels of the clam Hbs, from sulfide-rich and sulfide-poor environments showed a significant decrease of expression in the symbiont-containing tissue for those clams in a sulfide-poor environment, suggesting that the sulfide concentration may be involved in the regulation of these proteins. Gene expression evaluation of the two HbI mRNA variants indicated that the longer variant is expressed at higher levels than the shorter variant in both environments.
Real-time performance-driven facial animation with 3ds Max and Kinect

This paper presents a novel performance-driven realtime facial animation system with 3ds Max and Kinect. The user performs in a natural environment without any marker, and the 3D facial video of the user is captured with Kinect. The 2D key facial points are tracked with improved Active Appearance Model, and a set of Action Units are derived with the iterative closest point algorithm. Based on the two rough regions of eyes, we performed extra operations to track blinks and pupil motions. The data of Action Units are transmitted as control parameters using the Musical Instrument Device Interface communication protocol to drive the skeleton-based skinning facial model rendering with 3ds Max. The prototype system has been developed and tested on a common PC platform. Experimental results demonstrated that the digital avatar can mimic general apparent facial expressions of the performer, and the facial animation can reach 30 frames per second as the video capture rate.
Continuous User Experience Development

Continuous approaches for software engineering such as continuous planning, development, and operations are becoming increasingly popular in agile software companies. It means that also user-centered design practitioners and practices need to adapt to both possibilities and challenges the increasingly rapid and more tightly integrated software engineering environment induces. Such issues include planning continuously throughout the life cycle instead of upfront planning, delivering user value whenever something is ready instead of delivering working software at the end of time-boxed iterations, and experimenting with real users instead of conducting traditional user studies and tests. In this position paper we discuss how user experience work can be organized with continuous software development.
Schwinger's oscillator method, supersymmetric quantum mechanics and massless particles

We consider Schwinger's method of angular momentum addition using the SU(2) algebra with both a fermionic and a bosonic oscillator. We show that the total spin states obtained are: one boson singlet state and an arbitrary number of spin-1/2 states, the later ones are energy degenerate. It means that we have in this case supersymmetric quantum mechanics and also the addition of angular momentum for massless particles. We review too the cases of two bosonic and two fermionic oscillators.
An Empirical Study of the Effect of Coherent and Tailored Document Delivery as an Interface to Organizational Websites

Abstract: Increasingly, people find information about corporations through their web sites, as opposed to reading printed brochures. Typically, the only tools they have to find that information is searching and browsing. But can we do better with a modest user model and coherent delivery? Can we provide, through the web, more relevant and coherent information about a corporation, information specially tailored to specific clients and presented in a useful and understandable manner? Our conjecture was that a tailored hypermedia system offering tailored and coherent information would indeed provide a good alternative to the current search-and-browse facilities, also allowing corporations to be more responsive to their clients' needs. In this paper, we present a preliminary study aimed at testing this hypothesis. We designed an experiment aimed at investigating the effect of delivering coherent and tailored information in response to user's query, in comparison to delivering the results of conventional search engines. We employed our experimental system, PERCY, which exploits information retrieval, user modeling and discourse-oriented technologies to retrieve and select parts of existing documents from CSIRO website and assemble them back into a coherent and tailored webpage. Our experiment consisted of asking users to evaluate and compare the results produced by PERCY and those produced by a typical search engine, given a query about some project or research topic at CSIRO. Our experimental results indicate that users preferred the output of Percy, as it attracted more their attention and they understood the results better.
Hippocampal Volume Is Related to Complexity of Nesting Habitat in Leach’s Storm-Petrel, a Nocturnal Procellariiform Seabird

The hippocampal and telencephalon volumes of the nocturnal Leach’s storm-petrel (Oceanodroma leucorhoa, n = 15) were compared with published data for food-storing and non-storing Passerines. The hippocampus to telencephalon ratio of Leach’s storm-petrels is intermediate between food-storing and non-storing birds. Leach’s storm-petrels taken from nesting burrows in wooded habitat had a larger relative hippocampal volume than those taken from burrows in an open meadow. Relative olfactory volume did not differ between woods and open-nesting storm-petrels. The larger relative hippocampal volume of storm-petrels may be associated with increased spatial demands of returning to their nests at night in the darker, more navigationally complex woods. It is not known whether the larger hippocampus in storm-petrels from the woods is due to selection on different subpopulations or whether experience in a more complex environment results in greater hippocampal volume. Hippocampal volume from the brain of one diurnal Procellariiforme, the northern fulmar (Fulmaris glacialis), fell within the range of non-storing species, which supports the view that hippocampal enlargement in the storm-petrel is related to the spatial demand of returning to the nest at night.
A characterization of the Z^n lattice

We use theta series and modular forms to prove that Z^n is the only integral unimodular lattice of rank n without characteristic vectors of norm <n, i.e. the only integral unimodular lattice not containing a vector w such that (w,w)<n and 2|(v,v+w) for all lattice vectors v. By the work of Kronheimer and others on the Seiberg-Witten equation this yields an alternative proof of a theorem of Donaldson on the geometry of 4-manifolds.
Provably Total Functions in Bounded Arithmetic Theories Ri 3 , U i 2 and V i 2

This paper investigates the provably total functions of fragments of firstand second-order Bounded Arithmetic. The (strongly) Σi -definable functions of S i−1 3 and R i 3 are precisely the (strong) FP Σpi−1 3 [wit, log O(1)] functions. The Σ i -definable functions of V i−1 2 and U i 2 are the EXPTIME Σ i−1 [wit, poly] functions and the Σ i definable functions of V i 2 are the EXPTIME Σ i -functions. We give witnessing theorems for these theories and prove conservation results for Ri 3 over S i−1 3 and for U i 2 over V i−1 2 .
Callous-unemotional traits and emotion processing in typically developing youths

The aim of this thesis was to investigate whether callous unemotional (CU) traits in typically developing children and adolescents show similar associations with behavioural and neural responses as seen in clinical and forensic populations. Three investigations, presented in Chapters 3-5, focussed on the behavioural and neural correlates of emotion recognition and processing. An exploration of the behavioural recognition of the six basic emotions (happiness, sadness, fear, anger, disgust, and surprise) indicated negative correlations between levels of CU traits and accurate recognition of sadness and disgust (Chapter 3). Based on an examination of neural correlates of emotion recognition during a subliminal emotion processing task, which included angry and fearful faces, it was concluded that activation levels in the bilateral amygdala and insula during fear processing, but not anger processing, were negatively correlated with CU traits (Chapter 4). Finally, based on an investigation of the structural integrity in the bilateral uncinate fasciculus (UF), which is a white matter tract reported to be relevant in psychopathy, it was concluded that fractional anisotropy in the right UF was negatively associated with CU traits, but only in youths aged 16-18 years (Chapter 5). These investigations produced novel findings and advanced the understanding of the dimensional nature of CU traits in typically developing youths.
