Interaction in a Natural Environment: Estimation of Customer's Preference Based on Nonverbal Behaviors

We examined the interaction in face-to-face selling situation. In particular, we examined how customer's nonverbal behaviors were related to their preference in a natural environment. We found that customers' body posture could be a good predictor about their preference. We also found that estimation on customer's preference could be achieved from two nonverbal behaviors better than single behavior. We discuss the present contributions toward constructing the efficient agent systems.
Validation of a generic GQM based measurement framework for software projects from industry practitioners

Software projects today are often characterized by poor quality, schedule overruns and high costs. One of the reasons for this failure is the lack of management visibility or metrics for making the right decisions at the right time for corrective actions. But most of the software metrics proposed are theoretical and have little relevance in real-world projects. Given that software engineering is essentially a cognitive activity, an effective measurement framework which is validated empirically is needed to control the project and give directions to accomplish the project goals of the stakeholders. However, defining and implementing the right measurement framework is extremely challenging requiring a cross pollination of systems development and project management streams. This paper examines how a stakeholder driven Goal-Question-Metric (GQM) measurement framework was derived and empirically validated with a survey from seasoned software professionals.
Hermeneutics framework: integration of design rationale and optimizing software modules

To tackle the evolution challenges of adaptive systems, this paper argues on the necessity of hermeneutic approaches that help to avoid too early elimination of design alternatives. This visionary paper proposes the Hermeneutics Framework, which computationally integrates a design rationale management system, an auto-adaptive control system and a reflective and modular event-driven language runtime together. The Hermeneutics Framework is, among others, suitable for implementing dynamic adaptive software systems that undergo intensive evolution cycles.
Development of class-level and instance-level design models for distributed-object software

Leading the pack of new-generation software applications are distributed applications, which are well suited to designs based on distributed objects. To help cope with the increased complexity of such systems, developers can benefit from formal methods and associated tools that support specification and analysis. This paper presents a Petri net motivated approach for modeling distributed-object software. Both class-level and instance-level models are defined, with the goal of supporting scalable designs. Model analysis, with state space reduction due to symmetry among object instances, is also considered. A case-study is presented to illustrate the specific modeling and analysis features.
Local Cell Death Changes the Orientation of Cell Division in the Developing Drosophila Wing Imaginal Disc Without Using Fat or Dachsous as Orienting Signals

Drosophila imaginal disc cells exhibit preferred cell division orientations according to location within the disc. These orientations are altered if cell death occurs within the epithelium, such as is caused by cell competition or by genotypes affecting cell survival. Both normal cell division orientations, and their orientations after cell death, depend on the Fat-Dachsous pathway of planar cell polarity (PCP). The hypothesis that cell death initiates a planar polarity signal was investigated. When clones homozygous for the pineapple eye (pie) mutation were made to initiate cell death, neither Dachsous nor Fat was required in pie cells for the re-orientation of nearby cells, indicating a distinct signal for this PCP pathway. Dpp and Wg were also not needed for pie clones to re-orient cell division. Cell shapes were evaluated in wild type and mosaic wing discs to assess mechanical consequences of cell loss. Although proximal wing disc cells and cells close to the dorso-ventral boundary were elongated in their preferred cell division axes in wild type discs, cell shapes in much of the wing pouch were symmetrical on average and did not predict their preferred division axis. Cells in pie mutant clones were slightly larger than their normal counterparts, consistent with mechanical stretching following cell loss, but no bias in cell shape was detected in the surrounding cells. These findings indicate that an unidentified signal influences PCP-dependent cell division orientation in imaginal discs.
Combining the Estimated Date of HIV Infection with a Phylogenetic Cluster Study to Better Understand HIV Spread: Application in a Paris Neighbourhood

Objectives To relate socio-demographic and virological information to phylogenetic clustering in HIV infected patients in a limited geographical area and to evaluate the role of recently infected individuals in the spread of HIV. Methods HIV-1 pol sequences from newly diagnosed and treatment-naive patients receiving follow-up between 2008 and 2011 by physicians belonging to a health network in Paris were used to build a phylogenetic tree using neighbour-joining analysis. Time since infection was estimated by immunoassay to define recently infected patients (very early infected presenters, VEP). Data on socio-demographic, clinical and biological features in clustered and non-clustered patients were compared. Chains of infection structure was also analysed. Results 547 patients were included, 49 chains of infection containing 108 (20%) patients were identified by phylogenetic analysis. analysis. Eighty individuals formed pairs and 28 individuals were belonging to larger clusters. The median time between two successive HIV diagnoses in the same chain of infection was 248 days [CI = 176–320]. 34.7% of individuals were considered as VEP, and 27% of them were included in chains of infection. Multivariable analysis showed that belonging to a cluster was more frequent in VEP and those under 30 years old (OR: 3.65, 95 CI 1.49–8.95, p = 0.005 and OR: 2.42, 95% CI 1.05–5.85, p = 0.04 respectively). The prevalence of drug resistance was not associated with belonging to a pair or a cluster. Within chains, VEP were not grouped together more than chance predicted (p = 0.97). Conclusions Most newly diagnosed patients did not belong to a chain of infection, confirming the importance of undiagnosed or untreated HIV infected individuals in transmission. Furthermore, clusters involving both recently infected individuals and longstanding infected individuals support a substantial role in transmission of the latter before diagnosis.
Which Factors Unexpectedly Increase Depressive Symptom Severity in Patients at the End of a Cardiac Rehabilitation Program?

Objective To investigate predictors of depressive symptom aggravation at the end of a cardiac rehabilitation (CR) program. Methods The design of the study was retrospective. The administrative data were obtained from the database of the CR department of a heart hospital in Iran. The demographic and clinical information of 615 CR patients between January 2000 and January 2010 was analyzed using binary logistic regression analysis. Results The results showed that 10.7% of the patients completed the CR program with aggravated depressive symptoms. After adjustment for gender, age, and pre-intervention depression score, lower education level (p<0.05) and smoking (p<0.01) were significant predictors of increased depressive symptoms at the end of the program. Our model variables could explain 6% to 13% of the dependent variable variance. Conclusion The results suggest that targeting patients who are less literate or who smoke could allow for taking the required measures to prevent or control depression at the end of a CR program. It is suggested that future studies consider other variables.
On hypersurface quotient singularities of dimension 4

We consider geometrical problems on Gorenstein hypersurface orbifolds of dimension n≥4 through the theory of Hilbert scheme of group orbits. For a linear special group G acting on ℂn, we study the G-Hilbert scheme HilbG(ℂn) and crepant resolutions of ℂn/G for G the A-type abelian group Ar(n). For n=4, we obtain the explicit structure of HilbAr(4)(ℂ4). The crepant resolutions of ℂ4/Ar(4) are constructed through their relation with HilbAr(4)(ℂ4), and the connections between these crepant resolutions are found by the flop procedure of 4-folds. We also make some primitive discussion on HilbG(ℂn) for G the alternating group a#x1D504;n
Improving battery performance by using traffic shaping techniques

We present a new approach to minimizing energy consumption by addressing battery management techniques that exploit the charge recovery effect inherent to many secondary storage batteries. We review results that pertain to the capacity of a battery and its dependence on the intensity of the discharge current. The phenomenon of charge recovery that takes place under bursty or pulsed discharge conditions is identified as a mechanism that can be exploited to enhance the capacity of a battery. The bursty nature of many data traffic sources suggests that data transmissions may provide natural opportunities for charge recovery. We explore stochastic models to track charge recovery in conjunction with bursty discharge processes. Using the postulated model, we identify the improvement to battery capacity that results from a pulsed discharge driven by bursty stochastic discharge demand. The insight from this analysis leads us to propose discharge shaping techniques that trade-off energy efficiency with delay.
WAR Metaphors in Indonesian-English Political Discourse

This study is aimed at identifying WAR metaphors in Indonesian political discourse and their translation into English. The data were obtained from Tempo Magazine, during January to March 2018, with 29 political articles covering the political elections of 2018 and 2019. To discover the concept of metaphor, this study applied Conceptual Metaphor Theory (CMT) proposed by Lakoff and Johnson (1980). Metaphor Identification Procedure (MIP), formulated by Pragglejaz Group (2007), was used in this study to avoid intuition during metaphor identification. This study found that WAR metaphor was positively pervasive in Indonesian political discourse. There were 49 metaphorical war expressions with total 239 occurances. A cross-mapping from war domain to politics domain were soldier to political candidate, war strategy to campaign strategy, battleground to political elections, target to power, alliance to parties coalition, and weapon to votes. The conceptual mapping highlights politics as a battle for power and hides politics as an attempt to proper people. The implemented strategies in the transslation were 162 by providing the same metaphors, 29 by providing a different metaphor, 40 by providing literal paraphrases, and 8 by omiting the metaphors. Keywords—conceptual metaphor; WAR metaphor; translation strategy; political discourse

The DIVA (Data IntensiVe Architecture) system incorporates Processing-In-Memory (PIM) chips as smart-memory coprocessors to a microprocessor, with a separate memory-to-memory interconnect, thus exploiting the inherent memory bandwidth both on chip and across the system. DIVA targets several classes of bandwidth-limited applications, including multimedia applications and pointer-based and sparse-matrix computations. The DIVA project is building a prototype workstation-class system using VLSI PIM chips in place of standard DRAMs to demonstrate these concepts. We have recently fabricated the prototype PIM VLSI device. In this paper, we describe for the first time the DIVA PIM chip architecture, and in particular, its memory unit and its wide datapaths for exploiting bandwidth in computation, memory access and communication. We present detailed simulation results on eight benchmark applications. When just a single PIM chip is used, we still achieve a speedup of 3.3X over host-only execution. We show the contributions leading to this speedup from lower memory stall times, and benefits from 256-bit WideWord datapaths. Much more significant improvements are possible by exploiting coarsegrain parallelism across 32-64 PIM chips, the planned scale of the DIVA system, but these 1-PIM results suggest that A PIM-based architecture can yield significantly higher performance than a multiprocessor of a similar scale, and at a much reduced hardware cost.
MAPPING TEXTURE FROM MULTIPLE CAMERA VIEWS ONTO 3D-OBJECT MODELS FOR COMPUTER ANIMATION

An algorithm for the mapping of texture from multiple camera views onto a 3D model of a real object is presented. The texture sources are images taken from an object rotating in front of a stationary calibrated camera. The 3D model is represented by a wireframe built of triangles and is geometrically adjusted to the camera views. The presented approach aims at the reduction of texture distortion associated with the boundaries between triangles mapped from different camera views and disturbance due to not visible parts of the object surface. For this purpose adjacent triangles describing the surface of the 3D model are grouped to homogenous surface regions which are textured with a common image followed by a local texture filtering at the region boundaries. For triangles not visible in any camera view a filter has been developed which uses the texture from adjacent visible triangles for the generation of synthetic texture. Experimental investigations with different real 3D objects have confirmed the suitability of the proposed technique for computer animation applications.
Distributed Algorithm for Topology Control in Heterogeneous Ad-hoc Networks

A mobile ad hoc network is a collection of wireless terminals that can be deployed rapidly. Its deficiencies include limited wireless bandwidth efficiency, low throughput, large delays, and weak security. Integrating it with a well established cellular network can improve communication and security in ad hoc networks, as well as enrich the cellular services. The integration of heterogeneous wireless technologies can improve the network performance, thereby meeting the demands for different quality of service (QoS). Power heterogeneous ad hoc networks are characterized by link layer asymmetry: the ability of lower power nodes to receive transmissions from higher power nodes but not vice versa. Normally flooding occurs in Heteregeneous Networks. In this paper, we propose On demand Utility-Based Routing Protocol (OUBRP), which is designed to improve the efficiency of on-demand routing protocols under a Heterogeneous networking environment. Topology control in an ad-hoc network can provide better spatial reuse of the wireless channel and conserve power. Topology construction and maintenance is a challenging issue. A number of distributed topology control algorithms have been proposed to remove the need of a centralised controller. Distributed algorithms such as location information no topology (LINT), location information link state topology (LILT) and mobile-grid (MG), aim to achieve overall network connectivity and low transmission range by maintaining a minimum node degree value. In the case of a non-uniform node distribution, maintaining a minimum node degree can unnecessarily partition a network. In this paper, we propose a distributed algorithm that utilises one hop neighbours and their location information to maintain a number of critical links required to keep a connected network. Such critical links are included along with the links required to meet the node degree criterion. A distributed mechanism to construct and maintain a network topology is proposed, which 2 G. Anandhi and Dr. S. K. Srivatsa can be integrated as part of the neighbour discovery protocol. Furthermore, nodes collaborate to remove unidirectional links. A simulation based analysts of the proposed algorithm is provided for a number of node degree values. Simulations indicate that the proposed algorithm is able to achieve higher connectivity for different node distributions.
The RecMap Model of Active Recognition Based on Analogical Mapping

We propose an object recognition model based on analogical mapping and transfer. The objective of our model is to be able to generate and bind structural representations; and to recognize objects from a small set of primitives. The input is mapped to the associative memory and activation is spread upwards. Anticipations are generated through local mappings and transferred to be tested serially in the order of their relevance. Due to these mechanisms, our model is able to simulate phenomena such as object priming and global precedence effect. Additionally, it provides a framework for integrating visual perception and other higher-order cognitive processes.
Money, Interest Rates, and Exchange Rates with Endogenously Segmented Markets

We analyze the effects of money injections on interest rates and exchange rates when agents must pay a Baumol‐Tobin‐style fixed cost to exchange bonds and money. Asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money infrequently. When the government injects money through an open market operation, only those agents that are currently trading absorb these injections. Through their impact on these agents’ consumption, these money injections affect real interest rates and real exchange rates. The model generates the observed negative relation between expected inflation and real interest rates as well as persistent liquidity effects in interest rates and volatile and persistent exchange rates.
Empowering Education: A New Model for In-service Training of Nursing Staff

Introduction: In-service training of nurses plays an indispensable role in improving the quality of inpatient care. Need to enhance the effectiveness of in-service training of nurses is an inevitable requirement. This study attempted to design a new optimal model for in-service training of nurses. Methods: This qualitative study was conducted in two stages during 2015-2016. In the first stage, the Grounded Theory was adopted to explore the process of training 35 participating nurses. The sampling was initially purposeful and then theoretically based on emerging concept. Data were collected through interview, observation and field notes. Moreover, the data were analyzed through Corbin-Strauss method and the data were coded through MAXQDA-10. In the second stage, the findings were employed through ’Walker and Avants strategy for theory construction so as to design an optimal model for in-service training of nursing staff. Results: In the first stage, there were five major themes including unsuccessful mandatory education, empowering education, organizational challenges of education, poor educational management, and educational-occupational resiliency. Empowering education was the core variable derived from the research, based on which a grounded theory was proposed. The new empowering education model was composed of self-directed learning and practical learning. There are several strategies to achieve empowering education, including the fostering of searching skills, clinical performance monitoring, motivational factors, participation in the design and implementation, and problem-solving approach. Conclusion: Empowering education is a new model for in-service training of nurses, which matches the training programs with andragogical needs and desirability of learning among the staff. Owing to its practical nature, the empowering education can facilitate occupational tasks and achieving greater mastery of professional skills among the nurses.
The function of chitin synthases 2 and 3 in the Saccharomyces cerevisiae cell cycle

The morphology of three Saccharomyces cerevisiae strains, all lacking chitin synthase 1 (Chs1) and two of them deficient in either Chs3 (calR1 mutation) or Chs2 was observed by light and electron microscopy. Cells deficient in Chs2 showed clumpy growth and aberrant shape and size. Their septa were very thick; the primary septum was absent. Staining with WGA-gold complexes revealed a diffuse distribution of chitin in the septum, whereas chitin was normally located at the neck between mother cell and bud and in the wall of mother cells. Strains deficient in Chs3 exhibited minor abnormalities in budding pattern and shape. Their septa were thin and trilaminar. Staining for chitin revealed a thin line of the polysaccharide along the primary septum; no chitin was present elsewhere in the wall. Therefore, Chs2 is specific for primary septum formation, whereas Chs3 is responsible for chitin in the ring at bud emergence and in the cell wall. Chs3 is also required for chitin synthesized in the presence of alpha-pheromone or deposited in the cell wall of cdc mutants at nonpermissive temperature, and for chitosan in spore walls. Genetic evidence indicated that a mutant lacking all three chitin synthases was inviable; this was confirmed by constructing a triple mutant rescued by a plasmid carrying a CHS2 gene under control of a GAL1 promoter. Transfer of the mutant from galactose to glucose resulted in cell division arrest followed by cell death. We conclude that some chitin synthesis is essential for viability of yeast cells.
Exploring the relationship between awe and leisure: A conceptual argument

Abstract Leisure scholars are uniquely positioned to study awe. Anecdotally, the intertwined nature of awe and leisure has been well chronicled for centuries. In recent years, their relationship has been increasingly explored at the empirical level. Despite the clear connections, the enhanced level of scholarship has occurred with only sporadic contributions by scholars in parks, recreation, tourism, and leisure circles. The purposes of this manuscript are to identify attributes of awe, explore the relationship between awe and leisure, and consider the shared qualities of awe and leisure. A literature review identifies leisure settings in which awe has been chronicled to occur. Those settings are dichotomized in terms of natural and cultural landscapes, with wildlife and artistic expression noted respectively as potential elicitors of awe. Implications for parks, recreation, tourism, and leisure are discussed and include potential action points for decision makers and scholars, with specific emphasis on the potential to enhance the awe-related leisure body of research.
The Open University ’ s repository of research publications and other research outputs Designing an online mentoring system for self-awareness and reflection on lifelong learning skills Conference Item

The term ’awareness’ finds it roots in the research on Computer Supported Cooperative Work (CSCW) and often does not reflect the changed modi operandi in today’s connected world. In this paper we argue that the term ’awareness’ needs to be understood in a broader way when used in the context of networked learning. In Learning Networks, awareness is increasingly related to finding appropriate learning objects, peers and experts or the ’right’ learning path. We discuss this different understanding and formulate open questions dealing with awareness in Learning Networks and Personal Learning Environments as well as their connection to reflection and issues of technical feasibility.
