Innovating the Innovation Process: An Organisational Experiment in Global Pharma Pursuing Radical Innovation

The challenge of managing the fuzzy front end of the innovation process is particularly acute for large, multi-brand, research and development (R&D)-intensive firms. Poor performance at generating radical innovations has resulted in many large organisations seeking to innovate how they organise for innovation. This paper presents an inductive, longitudinal study of an organisational experiment that sought to get ‘game-changing, radical ideas’ into the new product development funnel of a top three pharma. The immediate outcomes of a team-based internal innovation tournament included 33 new product ideas, 14 of which were radical. The medium term outcome of the experiment was a reorganisation of how the firm now pursues radical innovation activities. We link these outcomes to team leadership, contrasting innovation processes, including decisions about how to incorporate the ‘voice of the consumer’. The inductive, longitudinal study suggests causal interconnections between innovation team leadership, innovation team processes, and innovation outcomes.
THE RELATIONSHIPS BETWEEN STUDENT ENGAGEMENT AND THEIR ACADEMIC ACHIEVEMENT

The purpose of this study was to examine the relationships between student engagement and academic achievement. In another saying, this study aimed at determining the extent to which student engagement explains or predicts academic achievement. The study was carried out with the correlational research. The research sample was made up of 304 students. Student Engagement Scale and Demographic Variables Form were used for data collection tools. For the analysis of the data, descriptive statistics, correlation analysis, twostep cluster analysis, independent samples t-test and regression analysis were applied. The results obtained via the analyses conducted revealed that there were significant relationships between the students’ academic achievement and student engagement as well as between their academic achievement and especially the dimensions of cognitive engagement, behavioral engagement and sense of belonging. In addition, it was found out that cognitive, behavioral and emotional engagements that is class engagement predicted academic achievement and explained it with a rate of 10%.
Applying Reused Steel Bars to New Constructions (A Case Study in Gaza Strip)

Demands for construction materials and for steel in particular are globally increasing. In 2008, the construction sector consumed 56% of the total 1088 million tons of steel demand. Steel production is a major contributor to greenhouse emissions with an estimated 25% of total CO2 emissions. Therefore, reusing and recycling steel could be beneficial in lowering the global levels of CO2 emissions. This paper examines the possibility of using steel form the debris of damaged buildings during the 2014 war on Gaza, Palestine. The lack of steel bars and their uprising prices in Gaza strip encouraged the trend of using used steel in new constructions. The paper examines the properties of used steel in comparison with the standards. It also compares between steel of known and unknown extraction sources and between steel extracted under an expert supervision and steel extracted by local residents. The validity of reused steel is examined through a process of Re-certification. The process includes applying a tensile and bend and re-bend test to used steel bars. The results indicate that some reused steel bars meet the specification for new constructions. The results also show that steel bars extracted under a specialist supervision shows better performance than those extracted by local steel collectors in Gaza.
Deterministic Performance Prediction Model for Rehabilitation and Management of Flexible Pavement

A deterministic performance prediction model for use in rehabilitation and management of flexible pavements is presented. The model utilizes the serviceability concept adopted by the American Association of State Highway and Transportation Officials (AASHTO) for use in the design of flexible pavements. The serviceability concept is defined through the introduction of the present serviceability index (PSI) that is related to the cumulative axle load applications by means of a performance curve. The performance curve for a particular pavement structural section can be estimated using an incremental solution of the AASHTO basic design equation. The constructed performance curve can be used in several applications related to pavement rehabilitation and management. These applications include evaluating potential pavement design and rehabilitation alternatives using appropriate performance indicators, developing asphaltic overlay design procedure, performing life-cycle analysis and pavement management applications. Pavement management applications include prediction of future pavement conditions and estimation of transition probabilities used in stochastic prediction models. The presented analyses and techniques are potentially useful for pavement engineers and can be used as an effective teaching tool for pavement design students.
A Statistical Approach for Dating Archaeological Context

This paper describes a statistical model developing from Cor- respondence Analysis to date archaeological contexts of the city of Tours (France) and also to obtain an estimated absolute timescale. The data set used in the study is reported as a contingency table of ceramics against con- texts. But, as pottery is not intrinsically a dating indicator (a date is rarely inscribed on each piece of pottery), we estimate dates of contexts from their finds, and we use coins to attest the date of assemblages. The model-based approach uses classical tools (correspondence analysis, linear regression and resampling methods) in an iterative scheme. Archaeologists may find in the paper a useful set of known statistical methods, while statisticians can learn a way to order well known techniques. No method is new, but their gathering is characteristic of this application.
Foam flows through a local constriction

We present an experimental study of the flow of a liquid foam, composed of a monolayer of millimetric bubbles, forced to invade an inhomogeneous medium at a constant flow rate. To model the simplest heterogeneous fracture medium, we use a Hele-Shaw cell consisting of two glass plates separated by a millimetric gap, with a local constriction. This single defect localized in the middle of the cell reduces locally its gap thickness, and thus its local permeability. We investigate here the influence of the geometrical property of the defect, specifically its height, on the average steady-state flow of the foam. In the frame of the flowing foam, we can observe a clear recirculation around the obstacle, characterized by a quadrupolar velocity field with a negative wake downstream the obstacle, which intensity evolves systematically with the obstacle height.

Single Channel Vocal Separation using Median Filtering and Factorisation Techniques

This paper deals with the problem of the extraction of vocals from single channel audio signals containing both vocals and other instruments, including both pitched instruments and percussion instruments. A novel median filtering-based approach for the extraction of vocal tracks is described, which is simple and efficient to implement. Further improvements in separation quality are then obtained by the application of tensor factorisation techniques to further extract residual instruments from the vocal mix. Finally, a novel use of non-negative partial matrix cofactorisation is demonstrated as a means of further improving separation quality. Here the original single channel mixture is partially cofactorised in conjunction with the separated vocal signal in order to obtain improved separation of the vocal and instrumental tracks. The effectiveness of these techniques is then demonstrated on a test set of real world signals.
Effects of advanced injection timing on performance and emission of a supercharged dual-fuel diesel engine fueled by producer gas from downdraft gasifier

This study presents effects of advanced injection timing on engine performance and emission characteristics of a supercharged producer gas-diesel dual fuel diesel engine fueled by producer gas from a downdraft gasifier. Original injection timing of engine was 14° before top dead center (BTDC), and tests were conducted at advanced three different injection timings (17°, 20°, and 23°) by changing thickness of copper shim. Experiments were carried out at a constant injection pressure (2 bar) with varying injection flow rates of both producer gas and air at different engine speeds and loads. Advancing injection timing in a supercharged engine showed that diesel fuel displacement and brake thermal efficiency increased, with a significant reduction in carbon monoxide emission and specific energy consumption compared with original injection timing of premixed producer gasdiesel dual fuel.
The Degree Measure as Utility Function over Positions in Networks

In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and utility. Using the fact that networks form a special class of cooperative TU-games, we provide a foundation for the degree measure as a von Neumann-Morgenstern expected utility function reflecting preferences over being in different positions in different networks. The famous degree measure assigns to every position in a weighted network the sum of the weights of all links with its neighbours. A crucial property of a preference relation over network positions is neutrality to ordinary risk. If a preference relation over network positions satisfies this property and some regularity properties, then it must be represented by a utility function that is a multiple of the degree centrality measure. We show this in three steps. First, we characterize the degree measure as a centrality measure for weighted networks using four natural axioms. Second, we relate these network centrality axioms to properties of preference relations over positions in networks. Third, we show that the expected utility function is equal to a multiple of the degree measure if and only if it represents a regular preference relation that is neutral to ordinary risk. Similarly, we characterize a class of affine combinations of the outdegree and indegree measure in weighted directed networks and deliver its interpretation as a von Neumann-Morgenstern expected utility function.
Uncertainty Treatment in Input-Output Analysis

TThis work provides an extensive overview of the input-output (IO) literature, both theoretical and empirical, dealing with the inherent IO data uncertainty issues. The survey is carried out on the basis of a specific uncertainty technique used, rather than taking a chronological overview approach, which also allows for easier comparisons and linking of the outcomes of the individual contributions. Thus, we discuss the literature within seven methodological blocks (sections), which include deterministic error analysis, econometric and other (non-Bayesian) statistical approaches, random error analysis and probabilistic approach, full probability density distribution approach, Monte Carlo analysis, Bayesian approach, and other techniques. Within each section, the literature on a certain topic is reviewed in its historical context, which helps to clarify the state of the art. Our main findings from this survey, related discussions, final remarks and observations are given in the concluding section.
Evaluation of e-performance analysis and assessment in the United Arab Emirates (UAE) Organizations

Increased competition, changing technology, and process re-engineering have changed the traditional employee practice and capability. To meet such demands, organizations and businesses are relying on communications technology to monitor and improve employee performance and productivity. Electronic performance management systems (e-PMS) are being used by many organisations to monitor the performance. The challenge for most organizations is that the use of technology to drive human performance is relatively new and not well understood. The review of the literature shows that very limited research has been conducted to assess the impact of e-PMS in the context of the Middle East. Therefore, the focus of this research is to provide an overall view on e-PMS. The result shows that critical issues and strategic priorities which should be taken into consideration by an Arab organization in formulating its goals to address the needs and requirements of its employees. Key words: Electronic performance management systems, performance appraisal, United Arab Emirates (UAE).
The Study and Practice on Teaching Reform of Signals and Systems Based on Comprehensive Talent Cultivation

"Signals and Systems" is the main technological base for the electric information program. The concept and method have already been widely applied to various aspects. With the development of information technology, existing course system and teaching contents are relatively lagging, so it is hard to meet demands of talent cultivation. There are lots of questions: repeated teaching contents with other courses, poor coordination, no organic whole, large mathematical analysis, weak linking theory with practice and disconnection among principles, methods and applications. As a result, it is urgent to reform the course and establish a kind of effective teaching model of the signal and system with the purpose of cultivating comprehensive talents. This is the important task of the current talent cultivation. In the paper, on the basis of the reflection on comprehensive talent cultivation, the author proposes specific measures on course teaching from teaching philosophy, teaching contents, teaching methods and teaching resources, etc. Keywords—Study and Practice; reverse teaching design; diversified teaching method; Signals and Systems
Amniotic Membrane versus Formocresol as Pulpotomy Agents in Human Primary Molars: An in vivo Study

Objective: To determine and compare the efficacy of Amniotic Membrane (AM) as a pulpotomy agent with Formocresol (FC) clinically and radiographically. Material and Methods: 30 deciduous molars warranted for pulpotomy in 24 children (4-9 years) were divided equally into two groups of 15 each. Group1: Amniotic membrane pulpotomy and Group 2: Formocresol pulpotomy, which was followed by placement of glass ionomer cement and stainless steel crown restoration. The patients were recalled after 1, 3, 6 and 9 months for clinical and radiographic evaluation. Fisher's exact test and Mcnemar test were used for statistical analysis. Results: Results indicated both clinically and radiographically amniotic membrane performed at par with formocresol. Conclusion: Amniotic membrane with its regenerative, antibacterial properties and the ability to deliver growth factors has shown promising results comparable to gold standard formocresol when used as a pulpotomy agent and hence can be recommended as an alternative pulpotomy agent.
The Unequal Effects of Liberalization: Theory and Evidence from India∗

This paper exploits the 1991 Indian liberalization to illustrate how such a reform may have unequal effects on industries and regions within a single country. We begin by developing a Schumpeterian growth model to analyze the effects on growth and inequality of liberalization reforms aimed at increasing entry. The main predictions of the model are: (i) liberalization fosters innovation (technology adoption), profits and growth, in industries that are initially close to the technological frontier, while it reduces innovation, profits and growth in industries which are initially far below the frontier; (ii) proworker labor regulations discourage innovation and growth in all industries and this negative effect increases with liberalization. We test these predictions in a 3-digit industry panel data set for the sixteen main states of India over the period 1980-1997. The empirical results confirm the main predictions of the model. We find that the 1991 liberalization in India had strong inequalizing effects, by fostering productivity growth and profits in 3-digit industries that were initially closer to the Indian productivity frontier and in states with more flexible labor market institutions. These findings emphasize that the initial level of technology and institutional context mattered for whether and to what extent industries and states in India benefited from liberalization. ∗We are grateful to the Leverhulme Trust and STICERD, LSE for financial support.
A Compact, Low-Profile Log-Periodic Meandered Dipole Array Antenna with an Artificial Magnetic Conductor

A compact and low-profile log-periodic meandered dipole array (LPMDA) antenna with an artificial magnetic conductor (AMC) is proposed. For compactness, a meander line configuration is implemented with dipole elements and optimized using a genetic algorithm (GA) to realize the LPMDA antenna. As a result, a size reduction of approximately 30% is achieved as compared to a conventional log-periodic dipole array antenna. To enhance the gain characteristics, the AMC ground plane configuration is realized with 9 × 9 unit cells for the LPMDA antenna. Two prototypes of the proposed LPMDA antennas with and without an AMC are fabricated and measured to verify its performance. The measured −10 dB reflection ratio bandwidths are 2.56 : 1 (0.85–2.18 GHz) and 2.34 : 1 (0.92–2.16 GHz) for the proposed LPMDA antennas with and without the AMC, respectively. The gain at the main beam direction within the operating frequency bandwidth is significantly improved from 3.94–7.17 dBi to 7.86–10.01 dBi by applying the AMC.
Long-Horizon Predictability of Equity REIT Returns: Is it There?

The predictability of stock returns has been one of the most discussed issues in financial empirical and theoretical research. Particularly, we observe the recent discovery of the relationship between housing market, consumption, and stock market and the significance of using housing or consumption related variables in predicting long-horizon stock returns. As the market capitalization of REITs continues to increase rapidly and REIT market also seems to demonstrate its distinctive characteristics, the REIT return predictability has important implications in investment decisions and REIT pricing theories. The objective of this paper is to examine whether the time-series, long-horizon in particular, predictability can be found in REIT returns following the classical predictive variables such dividend price ratio or recent framework based on housing and consumption factors. Using both conventional t-test and recent developed Bonferroni Q-test, we find that robust long-horizon predictability in equity REIT returns exists with only classical d-p ratio. Housing collateral values have marginal predicting power, but with opposite direction shown in stock returns. The use of housing collateral values as a predictor is worth further investigation.
Is there a Need for a Cloud Platform for European Smart Cities

This paper proposes an innovative solution for city administrators to provide 'intelligent' services to citizens and visitors exploiting Cloud computing and frequency identification technologies. Using the EPIC platform, cities can become 'smart' by extending their applications with a new set of technical, functional and business capabilities based on the particular requirements of each city and the needs of end users for applications. The applications deployed on EPIC will take the advantage of the platform services for scalability, sustainability and low operational cost becoming available to a pan-European (and possible worldwide) market. In addition, the EPIC Roadmap will simplify the process of extending existing applications or developing new 'smart' services for cities and leverage the involvement of enterprises and SME creating new business models and value networks.
How flexibility affects the wake symmetry properties of a self-propelled plunging foil

Abstract The wake symmetry properties of a flapping-foil system are closely associated with its propulsive performance. In the present work, the effect of the foil flexibility on the wake symmetry properties of a self-propelled plunging foil is studied numerically. We compare the wakes of a flexible foil and a rigid foil at a low flapping Reynolds number of 200. The two foils are of the same dimensions, flapping frequency, leading-edge amplitude and cruising velocity but different bending rigidities. The results indicate that flexibility can either inhibit or trigger the symmetry breaking of the wake. We find that there exists a threshold value of vortex circulation above which symmetry breaking occurs. The modification of vortex circulation is found to be the pivotal factor in the influence of the foil flexibility on the wake symmetry properties. An increase in flexibility can result in a reduction in the vorticity production at the leading edge because of the decrease in the effective angle of attack, but it also enhances vorticity production at the trailing edge because of the increase in the trailing-edge flapping velocity. The competition between these two opposing effects eventually determines the strength of vortex circulation, which, in turn, governs the wake symmetry properties. Further investigation indicates that the former effect is related to the streamlined shape of the deformed foil while the latter effect is associated with structural resonance. The results of this work provide new insights into the functional role of passive flexibility in flapping-based biolocomotion.
