Radical Innovation Without Collocation: A Case Study at Boeing-Rocketdyne

This paper describes how a unique type of virtual team, deploying a computer-mediated collaborative technology, developed a radically new product. The uniqueness of the team-what we call VC3 teams, for Virtual Cross-value-chain, Creative Collaborative Teams-stemmed from the fact that it was inter-organizational and virtual, and had to compete for the attention of team members who also belong to collocated teams within their own organizations. Existing research on virtual teams does not fully address the challenges of such VC3 teams. Using the case of Boeing-Rocketdyne, we describe the behavior of members of a VC3 team to derive implications for research on virtual teaming, especially for studying teams within emerging contexts such as the one we observed. The data we collected also allowed us to identify successful managerial practices and develop recommendations for managers responsible for such teams.
Energy-Optimal Dynamic Thermal Management: Computation and Cooling Power Co-Optimization

Conventional dynamic thermal management (DTM) assumes that the thermal resistance of a heat-sink is a given constant determined at design time. However, the thermal resistance of a common forced-convection heat sink is inversely proportional to the flow rate of the air or coolant at the expense of the cooling power consumption. The die temperature of the silicon devices strongly affects its leakage power consumption and reliability, and it can be changed by adjusting the thermal resistance of the cooling devices. Different from conventional DTM which aims to avoid the thermal emergency, our proposed DTM regards the thermal resistance of a forced-convection heat sink as a control variable, and minimize the total power consumption both for computation and cooling. We control the cooling power consumption together with the microprocessor clock frequency and supply voltage, and track the energy-optimal die temperature. Consequently, we reduce a significant amount of the temperature-dependent leakage power consumption of the microprocessor while spending a bit higher cooling power than conventional DTM, and eventually consume less total power. Experimental results show the proposed DTM saves up to 8.2% of the total energy compared with a baseline DTM approach. Our proposed DTM also enhances the Failures in Time (FIT) up to 80% in terms of the electromigration lifetime reliability.
Promoting Effects of Streptozotocin-induced Diabetes on Induction of Hepatic Preneoplastic Lesions by Diethylnitrosamine in Rats

The effects of streptozotocin (STZ)-induced diabetes on induction of hepatic preneoplastic lesions by diethylnitrosamine (DEN) were investigated in male Fischer rats. A single dose of STZ was injected intravenously either 2 weeks before or after initiation with DEN. The blood glucose levels were significantly elevated from 1 week after STZ-injection until autopsy. The numbers of GST-P positive foci at 1 week after DEN administration in the STZ-injected rats were similar to those in the non-diabetic rats. In contrast, both the numbers and areas of GST-P positive foci > 2 mm in diameter 8 weeks after DEN administration were increased significantly in the rats treated with STZ after DEN exposure compared with the non-diabetic control rats. The results suggest that hepatic preneoplastic lesions initiated with DEN are promoted by STZ treatment-inducing diabetes.
NEWS AND INTEREST RATE EXPECTATIONS: A STUDY OF SIX CENTRAL BANKS

In this paper we analyse the effect of news relating to the expected path of monetary policy on interest rate futures. Central banks’ transparency is in most respects much greater than it was a decade ago, and so central bank communication needs to be included as a potential source of news. We therefore consider four types of news: macroeconomic news, overseas news, monetary policy surprises and central bank communication. The effect of these types of news on daily changes in interest rate futures is estimated using an EGARCH model for a panel of six economies. We find that interest rate expectations respond to both macroeconomic and policy news, although the response to macroeconomic news is larger, especially once we include foreign news. Overall, the results suggest that the impact of the RBA’s communication policy is in line with other major central banks, and significantly influences (and informs) expectations of future monetary policy.
Longitudinal analysis of the role of insomnia in suicide risk amongst suicide ideators and attempters

Currently, identification of proximal risk factors of suicide is a primary focus of suicide research; however, knowledge of these risk factors is limited. Therefore, longitudinal studies aiming to identify proximal, time-varying predictors of suicidal behavior are needed to improve prediction and prevention of suicide behaviors. To date, several studies have reported significant associations among insomnia, suicide ideation, and suicidal behaviors. This study sought to examine the relationship between insomnia (ISI) and suicide risk (BSS) over time amongst a group of suicide ideators, single, and multiple suicide attempters who took part in a clinical trial comparing treatment as usual (TAU) to brief cognitive behavioral therapy (BCBT). Participants included 152 active-duty Army soldiers reporting past week suicide ideation with some intent and/or past month suicide attempt. Longitudinal growth modeling was used to test the effect of trajectories of variables, as well as to compare group means. Additionally, a two-intercept cross-lagged panel over time was created to determine if insomnia and suicide scores risk predict change at the next time point. BCBT participants experienced a significant negative trajectory of ISI, while TAU’s trajectory was nonsignificant. Suicide ideators and single attempters reported similar baseline and end-of-study levels of ISI. No differences in ISI trajectories were observed between suicide status groups. A two-intercept cross-lagged panel over time was created to model the ability of previous BSS and ISI scores to predict change in the following time points. Previous variable
APOE genotypes and dyslipidemias in a sample of the Portuguese population

Abstract The objective of this work was to study the distribution of apolipoprotein E ( APOE) genotypes in a sample of the Portuguese population, and its association with the dyslipidemias observed. Study participants were healthy users of local Public Health Laboratories in six regions of mainland Portugal (Porto, Vila Real, Viseu, Lisboa, Portalegre and Faro). A total of 779 men and 1153 women aged 15–74years agreed to participate. Fasting lipid levels and APOE genotypes were determined centrally at the National Institute of Health in Lisboa. The frequency distribution of APOE alleles was: ε2=5.3%, ε3=84.9% and ε4=9.8%. Dyslipidemias were present in 66.6% of men and 60.7% of women. Comparison of APOE genotypes and relative allele frequencies showed that in dyslipidemic compared to normolipidemic subjects, the ε4 allele was more frequent in both sexes, although in a more pronounced way in men than in women due to higher frequencies of ε3/ ε4 and ε4/ ε4 genotypes. The known association of the ε4 allele with high cholesterol levels, the association of the ε2 allele with low cholesterol levels, and the association of the ε2 allele with high levels of triglycerides and low levels of high-density lipoprotein-cholesterol were confirmed in this study.
BGP ROUTE FLAP DAMPING ALGORITHMS

Route flap damping (RFD) plays an important role in maintaining the stability of the Internet routing system. It functions by suppressing routes that persistently flap. Several existing algorithms address the issue of identifying and penalizing route flaps. In this paper, we compare three such algorithms: original RFD, selective RFD, and RFD+. We implement these algorithms in ns-2 and evaluate their performance. We also propose possible improvements to the RFD+ algorithm.
Application of Mobile Agent in Wide Area Pervasive Computing System

Current pervasive computing systems always focus on the local area network (LAN) environment, for example, an intelligent room or intelligent building. This paper uses mobile agent to implement the resource and service migration mechanism, and make the pervasive computing system adaptable to work in wide area networks (WAN). The work in this paper includes three parts: (1) introducing mobile agent into wide area pervasive computing system and presenting The Mobile Agent based Wide Area Pervasive Computing System (WAPCS). WAPCS uses mobile agents as the underlying facility to migrate the resources and services to the user’s environment in WAN; (2) presenting a high performance service migrating mechanism based mobile agent for WAPCS. This mechanism can effectively avoid the heavy communication overhead in WAN, and be fit to work in WAPCS; (3) presenting a novel service migrating mechanism for WAPCS: divided-domain and convergent resource migrating mechanism (DCRM). DCRM uses mobile agent to effectively reduce the system overhead for service migration in WAPCS.

Fault Tolerant on the Grid using Distributed Data Mining Services

Fault tolerance is an important issue in service-oriented architectures like Grid and Cloud systems, where many and heterogeneous machines are used. Fault Tolerance is a non-functional requirement that requires a system to continue to operate, even in the presence of faults.In this work we present a flexible fault tolerant which extends the service –oriented architecture for Distributed Data Mining services on Grid for all the machines (primaries and replica), in order to have each machine both serving client requests and acting as backup for the other machines. Where as in previously a mechanism for handling machine failures in a Grid environment is proposed. By this the users can achieve failure recovery whenever a crash can occur on a Grid node involved in the computation.
Developing appropriate Christian leadership amongst the Enga people of Papua New Guinea.

Effective Christian mission seeks to understand traditional cultural leadership values, patterns and styles in developing appropriate Christian leadership. Unnecessary conflict often occurs during leadership development, due to a lack of understanding of either traditional cultural patterns, or of the essential nature of Christian leadership as seen in the life, teachings and ministry of Jesus , or both. This thesis examines the influence that traditional leadership patterns have had on the developing of appropriate Christian leadership among the Enga people of Papua New Guinea. It examines in particular, the influence that the kamongo (big man) and tee (pig-exchange) paradigms had on the Enga Christian leaders' understanding and practice of their leadership within the new Christian framework. The process of contextualising the Christian faith, specifically the developing of appropriate leadership for the emerging indigenous churches is examined, firstly by utilising perspectives from the social sciences, including cultural anthropology, leadership and contextualisation theories, and secondly by a study of Jesus' modelling and teaching on leadership, and its implementation in the early church. A working definition of appropriate Christian leadership as, the contextually-contingent exercise of authority in the spirit of Jesus within a relationship of influence, to intentionally influence people and effect outcomes, is proposed. This research utilises two methodologies; firstly, a narrative case study providing ethnographic description of the social context drawn primarily from the author's fieldwork, and secondly an extensive theoretical re,-iew and use of relevant literature. These pair to drive a missiological reflection on and critique of the preliminary principles and models emerging from the developing of appropriate Enga Christian leadership, that is Christian leadership that is both Scripturally-faithful (JC+ EC Model) and contextually-authentic. A major theme of this research is the importance of understanding the continuing influence that deep-level cultural leadership paradigms exert in shaping indigenous leaders' motivations, patterns and behaviour in an emerging indigenous church. This study concludes with findings that include pointers for future research emerging from this research.
Dynamic shared Layer 1 VPN provisioning in next-generation SONET/SDH networks

Rapid advances in next-generation SONET/SDH and optical switching along with GMPLS control have enabled many new service provisioning capabilities. In particular, a key paradigm is the new Layer 1 virtual private network (L1 VPN) framework, which allows clients to directly provision their own services without deploying expensive infrastructures. This paper proposes novel L1 VPN resource management schemes for virtual concatenation-enabled next-generation SONET/SDH networks, using both centralized and distributed control. Detailed performance analysis results are also presented.
The feasibility of human haptic emotion as a feature to enhance interactivity and immersiveness on virtual reality game

Interactivity and immersiveness are important keys on exploration virtual reality game. Numerous researchers concentrate to augment visual acuity in order to get sensible visualization and animation. In addition, acoustic has also became other aspects to enhance immersiveness of virtual reality game. Recently, there is an issue involving haptic as part of stimulating interactivity between virtual characters and players in order to obtain more attention from players. This paper presents the feasibility of how human haptic emotion being applied in virtual reality game. The idea is that through a haptic device the human emotion is sent to the game engine in order to gain more interactivity and immersiveness. The role of the device is to act as a bridge to deliver emotion sense from virtual character interaction into players from the sense of touch side. We classify each emotion into several different magnitude frequencies that are generated from the haptic devices. The intention of the classification is to tell players about the virtual character emotion during the playing period. This approach will be of great benefit in making virtual reality game more lively and impressive.
Performance Analysis Of Bluetooth System Using Optimized Differential GFSK Demodulator

In this project, a simple demodulator for GFSK receivers is developed, which averages the phase based on the signal-to-noise ratio (SNR) maximizing criterion, and does not require knowledge of the exact modulation index. Compared to demodulators with similar complexity, such as the LDI, the presented receiver can achieve superior performance. In digital modulation, Gaussian frequency shift keying(GFSK) is one of the shifting technique. we are facing a challenging task in simple and high performance receivers for GFSK. In our project we develop an optimized differential GFSK demodulator and investigate the phase wrapping issue in its implementation. The Experimental results shows performance of bit error rate improvement in with conventional differential demodulators in both AWGN and flat fading channels. We also compare the simulation results with other exiting techniques like fading channels .
A Wayfinding Application Based on the Influence Area Spatial Model

In this paper we present a qualitative model of space based on the notion of influence area which is a portion of space surrounding an object. We discuss the cognitive foundation of the concept of influence area and show how it can be used to formally define the notions of neighborhood, distance and orientation. We show how this model allows us to convert an analogic representation of spatial objects (in a spatial conceptual map) into an equivalent logical representation in order to carry out various kinds of spatial reasoning. Then, we present a wayfinding application that uses this logical representation and produces a route and its description in natural language. Finally, we briefly discuss the cognitive plausibility of the results provided by the system that implements our model.
Composition and Fatty Acid Profile of Goat Meat Sausages with Added Rice Bran

A scientific consensus on the relationship between obesity, obesity related diseases, and diet has emerged. One of the factors is overconsumption of the red meats such as pork and beef. Goat meat has the potential to replace these traditionally consumed meats. Rice bran is a rich source of antioxidants such as vitamin E. In this study, goat meat sausages were formulated to contain 0, 1.5 or 3 percent stabilized rice bran. Proximate and fatty acid composition, α-tocopherol, cholesterol concentration, and antioxidant activities of cooked goat meat sausages containing varying percentages of rice bran were measured. Data were analyzed using a fixed effects model. The fat percentage in the goat meat sausages increased in response to increasing rice bran percentages (P < 0.001). Saturated fatty acids concentration decreased linearly (P < 0.01), while unsaturated fatty acids and omega-3 and omega-6 fatty acids increased linearly in response to increasing rice bran percentages (P < 0.05). The concentration of α-tocopherol in sausages increased linearly in response to increasing rice bran percentages (P < 0.01). Also, antioxidant activity increased linearly in sausages in response to added rice bran (P < 0.01). The cholesterol concentration of sausages did not vary significantly in response to added rice bran.

Learning shift-invariant sparse representation of actions

A central problem in the analysis of motion capture (Mo-Cap) data is how to decompose motion sequences into primitives. Ideally, a description in terms of primitives should facilitate the recognition, synthesis, and characterization of actions. We propose an unsupervised learning algorithm for automatically decomposing joint movements in human motion capture (MoCap) sequences into shift-invariant basis functions. Our formulation models the time series data of joint movements in actions as a sparse linear combination of short basis functions (snippets), which are executed (or “activated”) at different positions in time. Given a set of MoCap sequences of different actions, our algorithm finds the decomposition of MoCap sequences in terms of basis functions and their activations in time. Using the tools of L1 minimization, the procedure alternately solves two large convex minimizations: Given the basis functions, a variant of Orthogonal Matching Pursuit solves for the activations, and given the activations, the Split Bregman Algorithm solves for the basis functions. Experiments demonstrate the power of the decomposition in a number of applications, including action recognition, retrieval, MoCap data compression, and as a tool for classification in the diagnosis of Parkinson (a motion disorder disease).
The Retrograde IFT Machinery of C. elegans Cilia: Two IFT Dynein Complexes?

We analyzed the relatively poorly understood IFT-dynein (class DYNC2)-driven retrograde IFT pathway in C. elegans cilia, which yielded results that are surprising in the context of current models of IFT. Assays of C. elegans dynein gene expression and intraflagellar transport (IFT) suggest that conventional IFT-dynein contains essential heavy (CHE-3), light-intermediate (XBX-1), plus three light polypeptide chains that participate in IFT, but no “essential” intermediate chain. IFT assays of XBX-1::YFP suggest that IFT-dynein is transported as cargo to the distal tip of the cilium by kinesin-2 motors, but independent of the IFT-particle/BBSome complexes. Finally, we were surprised to find that the subset of cilia present on the OLQ (outer labial quadrant) neurons assemble independently of conventional “CHE-3” IFT-dynein, implying that there is a second IFT-dynein acting in these cilia. We have found a novel gene encoding a dynein heavy chain, DHC-3, and two light chains, in OLQ neurons, which could constitute an IFT-dynein complex in OLQ neuronal cilia. Our results underscore several surprising features of retrograde IFT that require clarification.
