Adaptive Idea Screening Using Consumers

Following a successful idea generation exercise, a company might easily be left with hundreds of ideas generated by experts, employees, or consumers. The next step is to screen these ideas and identify those with the highest potential. In this paper we propose a practical approach to involving consumers in idea screening. Although the number of ideas may potentially be very large, it would be unreasonable to ask each consumer to evaluate more than a few ideas. This raises the challenge of efficiently selecting the ideas to be evaluated by each consumer. We describe several idea-screening algorithms that perform this selection adaptively based on the evaluations made by previous consumers. We use simulations to compare and analyze the performance of the algorithms as well as to understand their behavior. The best-performing algorithm focuses on the ideas that are the most likely to have been misclassified as “top” or “bottom” ideas based on the previous evaluations, and avoids discarding ideas too fast by adding random perturbations to the misclassification probabilities. We demonstrate the convergent validity of this algorithm using a field experiment, which also confirms the convergence pattern predicted by simulations.
Handling Optimization under Uncertainty Problem Using Robust Counterpart Methodology

In this paper we discuss the robust counterpart (RC) methodology to handle the optimization under uncertainty problem as proposed by Ben-Tal and Nemirovskii. This optimization methodology incorporates the uncertain data in U a so-called uncertainty set and replaces the uncertain problem by its so-called robust counterpart. We apply the RC approach to uncertain Conic Optimization (CO) problems, with special attention to robust linear optimization (RLO) problem and include a discussion on parametric uncertainty for that case. Some new supported examples are presented to give a clear description of the used of RC methodology theorem.
Using deep-neural-network to extend videos for head-mounted display experiences

Immersion is an important factor in video experiences. Therefore, various methods and video viewing systems have been proposed so far. Although head-mounted displays (HMDs) are home-friendly and more available among these devices, they can provide an immersive video experience owing to their wide field-of-view (FoV) and separation of users from the outside environment. They are often used for panoramic and stereoscopic VR videos, but the demand for viewing standard plane videos has increased in recent years. However, the theater mode, which restricts the FoV, is basically used for viewing plane videos. Thus, the advantages of HMDs are not fully utilized. Therefore, we explored an effective method for viewing plane videos by an HMD, in combination with view augmentation by LED implants to the HMD. We used deep neural network (DNN) to generate images for peripheral vision and wide FoV customization.
Low Soil Fertility Tolerance in Landraces and Improved Common Bean Genotypes

Soil mineral defidendes or toxicities adversely affect common bean (Phaseolus vulgaris L.) production worldwide. Cultivars tolerant to low soil fertility (LF) should support sustainable farming systems and reduce production costs and farmers' dependence on fertilizes Our objective was to identify LF tolerant landraces and improved common bean genotypes. We systematically screened 5000 to 5500 landraces and improved genotypes for LF tolerance at Popayan and Quilichao, Colombia, between 1978 and 1998. Mean LF intensity index across locations for seed yield ranged from 0.35 to 0.68. Average seed yield reduction over five cropping seasons was 53%. Seed yield, biomass, and HI were positively associated in LF and high soil fertility (HF). LF tolerance was identified in eight landraces and 14 improved genotypes. All landraces were from Middle America (MA), belonging to common bean races Durango, Jalisco, and Mesoamerica. All improved genotypes except one (A 36) also possessed characteristics of and involved one or more LF tolerant MA landraces in their pedigree. There was considerable variation for seed, plant, and maturity characteristics among LF tolerant genotypes. In LF, mean seed yield for landraces ranged from 856 kg ha -1 for 'Apetito' to 332 kg ha -1 for G 19833. Among improved genotypes, A 774 had the highest (948 kg ha -1 ) and CAP 4 the lowest (651 kg ha -1 ) seed yield. Reduction in seed yield due to LF ranged from 31% for A 36 to 63% for CAP 4. All landraces and seven improved genotypes had either a below average or average LF susceptibility index. Use of these LF tolerant landraces and improved genotypes should be maximized in breeding and genetic studies to enhance sustainable farming systems.
A semi-discretization approach to buckling behavior of thin-walled members

The classic stability analysis of thin-walled columns is based on ‘‘in-plane rigid’’ cross-section displacement modes corresponding to: Uniform axial extension, major axis bending, minor axis bending and torsion with related warping. An important feature missing here is the deformation of the cross section, which undergoes in-plane deformations by local and distortional modes. This paper deals with a novel method based on solution of the differential equations of GBT obtained through semi-discretization and application of beam constraints. In contrast to the traditional GBT formulations, this novel approach finds the exact modes shapes and amplitude solutions of the reduced order GBT equations related to the discretized cross section. For a more elaborate description see the companion papers, [1-5]. In this conference paper the novel approach is extended by including the initial stress terms. This leads to a modified set of coupled homogeneous differential equations of GBT with initial stress for identification of distortional buckling modes. In this paper we seek simple instability solutions using these GBT initial stress equations for the classical simply supported columns with constrained transverse displacements at the end sections and a constant axial initial stress. Based on the known boundary conditions the reduced order differential equations are solved by introducing the relevant trigonometric solution function and solving the related eigenvalue problem. This directly gives us the cross-section buckling mode shape and the eigenvalue corresponding to the bifurcation load factor. An illustrative example is given including development of classic buckling curves and comparison of results with finite element results found using Abaqus as well as with FSM and conventional GBT results found using the freely available software packages CUFSM [6] and GBTUL [7].
A multi-objective approach for the clustering problem in wireless ad hoc networks

Ad hoc networks are infrastructure-less computer networks consisting of heterogeneous mobile devices connected by wireless links. The devices are essentially faced to several limitations in terms of embedded energy, processing power, bandwidth, and internal memory. Clustering has been introduced in ad hoc networking to provide hierarchy and stability and to support information circulation reduction, energy management, and scalability. It consists of a process of self-aggregation of nodes into a set of sub-networks called clusters where each cluster would be managed by a master node called cluster centre responsible for gathering, maintaining and updating the cluster topology information as well as ensuring the data routing over the network. The set of cluster centres institutes a temporary network core that enhances the topology maintenance. From a graph perspective, this set represents a dominating set, that is a set of nodes such that each node of the network is either an element or adjacent to at least one element of this set. This paper develops a constrained bi-objective optimisation model for ﬁnding a dominating set that provides a trade-o ﬀ between maximising the energy amount and minimising the cardinality. A bi-objective simulated annealing meta-heuristic for constructing near-optimal solutions is then presented.
The Politics of Speculative Attacks in Industrial Democracies

Recent models of speculative currency crises contend that market expectations of policy behavior can trigger a speculative attack. We argue that political processes and partisan objectives inform expectations about the government's commitment to the exchange rate. First, market actors anticipate periods when the partisan identity of a government may change through an election or a cabinet collapse. Second, party labels provide information to currency traders about the policy objectives of a potential government. Consequently, we contend that the probability of a speculative attack will be higher when markets expect the cabinet to end and when the cabinet dissolution is likely to produce a leftward shift in policy. A discrete timesurvival model is used to estimate the probability that a cabinet will dissolve in any given month for sixteen parliamentary democracies from 1970 to 1995. The predicted values are then used as a proxy for market expectations in a model of speculative currency crises.
The Impact of Innovation of the Construction Industry in Ghana

The essence of this paper therefore, is to bring out the impact of innovation of the Construction industry in Ghana and also to establish tangible and intangible benefits associated with innovation. Analysis of the relevant literature indicates the impact and the problem of slow adaptation of innovation and new ways of working within the construction industry is a great concern to most organization that operates within and outside the industry. To bridge this conservatism attitude of innovation in the industry, it is fundamental to explore the impact and for that matter the benefits of innovation within the industry. This paper however, seeks to embark on this investigation on the impact of innovation and to bring to light its related benefits and how these would be achieved. Data were collected among construction professionals (Consultants) and Contractors via questionnaires supported by informal interviews. Analysis of the data was done using simple percentage method and the findings were represented in the form of pie-chart and bar-chart using micro-soft excel programme. The study established that innovation within an industry brings about increased in economic growth and profitability. The study also revealed that ease of working at a lower cost with much precision is assured when there is innovation Recommendation of effective coordination between Consultants and Contractors must exist to facilitate innovation beginning from research and development set-up within the firms.

Quantile momentum

A stock portfolio based on momentum strategies buys stocks that have recently performed well and sells (or shorts) stocks that have recently performed poorly. The most commonly used measure of past performance (momentum) of a stock is its average return over the previous 2 to 12 months. In this paper, we propose a diﬀerent set of measures of past performance based on the quantiles of past returns and investigate the performance of momentum portfolios based on such measures. We also introduce a robust version of the proposed quantile momentum by locally smoothing data before ranking. It is shown that the portfolios under these proposed alternative momentum measures can have very diﬀerent returns from one another, as well as from the standard portfolio based on the average. We also consider the correlations of portfolio returns between the alternative strategies and their combinations. A well known feature of momentum portfolios is that they carry incidental β exposures depending on whether the market has been rising or falling. A practical matter for portfolio managers is the extent to which momentum can be improved by neutralizing the incidental β exposures. We investigate how the various deﬁnitions of momentum are likely to aﬀect the incidental β exposures in long and short momentum portfolios.
Global Justice and the Shift in Property Rights for Plant Genetic Resources

Although new technologies in plant breeding have the potential to reduce poverty and improve global food security, a shift in property regime for plant genetic resources (PGRs) prevents this potential from being realised. As the emergence of biotechnology has increased the value of PGRs, rents-seeking behaviour by the plant breeding industry spurred the emergence of intellectual property rights (IPRs) for improved plant varieties. Whereas this system is globally implemented through the TRIPS agreement, biodiversity-rich developing countries increasingly use the Convention on Biological Diversity (CBD) to protect their PGRs through state sovereignty. By using an economic perspective, this article aims to explain the appropriation of PGRs and the efficiency rationale that is used for its justification. However, as this perspective disregards the alarming consequences for smallholder farmers in developing countries, a global justice perspective is used to explore these effects. Focusing on distributional justice and the provision of the right to food, this article will demonstrate that the property regime shift for PGRs leads to decreased availability of, and access to, crops that are used by resource-poor farmers. Instead of promoting organic agricultural practices, based on the diversity of traditional seed systems and minimal external inputs, this regime merely stimulates the growth of an unsustainable and highly concentrated seed industry. The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) and Consultative Group on International Agriculture Research (CGIAR) seem to be most promising in challenging the shift in property regime for PGRs and the global justice concerns this shift entails.
An Algorithm for Modeling and Interpretation of Seismoelectric Data

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the effect of an electric field due to DC current on the propagation of seismic waves by pseudo spectral time domain method, or the more general concept of seismoelectric coupling effect. In this research, poroelastic equations were used for seismic waves and Maxwell’s equations for lectromagnetic waves. Additionally, the seismoelectric effect or charge density, electrical conductivity, dielectric permittivity function, fluid viscosity and zeta potential were determined. DC electric field variations were compared with results of a physical experiment conducted in a modeled environment. The results revealed that DC electric significantly affected the propagation of elastic energy through seismoelectric coupling in a wide range of seismic frequency widths. Additionally, the boundaries of the substrata were specified using the horizontal component of the electric field of the magnetic wave
Strategic Entrepreneurship: Exploring Different Perspectives of an Emerging Concept

Within the entrepreneurship and strategic management domains there has been a movement by scholars to combine certain aspects of both areas to create a new concept of strategic entrepreneurship. To date, however, there remains much to know about what constitutes this concept. This special issue is the result of a unique research conference in Germany where some of the world's most renowned scholars gathered to explore this concept in depth. The set of articles in this special issue examine different perspectives that relate to strategic entrepreneurship and we believe contribute to the growing body of knowledge on this concept by examining diverse scholarly topics. This introduction provides the overview of the perspectives contained in strategic entrepreneurship and argues for the importance of embracing diverse views at this stage rather than attempting to restrict the analysis of this emerging topic.

Residential satisfaction and social integration in public low cost housing in Malaysia

The research examined the relationship between social integration and residential satisfaction of residents in low cost housing in Malaysia. Two urban and non-urban areas in Selangor were chosen for this study involving 472 respondents. 58% of the respondents are Malay, 22% Chinese and 20% Indians. It was shown that residents with strong residential attachments and high levels of satisfaction are actively involved in the community activities held in their neighbourhood. It was also found that factors such as default in the physical structures of the house and poor social and physical environments could affect the social integration in the neighbourhood. Therefore properly planned residential projects with attention given towards residential satisfaction need to be considered because they can help foster the process of socializing people into communities.
Burst pressure of phaseguide structures of different heights in all-polymer microfluidic channels

We present an experimental investigation of the burst/overflow pressure of water and a representative surfactant-containing buffer in microfluidic channels with phaseguide structures oriented at an angle of 90° to the channel length as a function of their height, . The all-polymer chips were fabricated by injection moulding and sealed by ultrasonic welding. Channels with a height of 200 m and widths of 1 mm or 3 mm were investigated for five values of between 8 m and 82 m. Phaseguide structures without branches and with branches at angles = 45°, 60° and 75° were studied. All phaseguide structures were found able to pin both liquids and the burst pressure was found to increase approximately linearly with the height of the phaseguide from about 100–350 Pa for water and from about 25–200 Pa for the buffer. The burst pressure was found not to depend on the channel width and it was only weakly influenced by the presence of a branch on the phaseguide. For phaseguides with a branch, the liquid was always found to burst at the branch location. The measured burst pressures were compared to those estimated using a simple theory. The knowledge obtained in this study enables simple tuning of liquid spreading and overflow in microfluidic channels by use of phaseguide structures with different heights and it also provides a set of systematic experimental data to be compared with simulations/theory.
Osteopontin expression in polarized MDCK cells.

The aim of this study is to indicate expression of osteopontin (OPN) in Madin-Darby Canine Kidney (MDCK) cells with different confluences (10, 50, 90, 100%). OPN expression were investigated by western blotting. An increase in OPN expression was observed due to the increased confluency and subsequent initiation of polarization. Expression profiles of flotillin-2 in the same cells were used as a control, since this protein is ubiquitously produced in MDCK cells and its expression rates are independent of confluence and / or polarization. Intracellular distribution of OPN was also monitored by confocal microscopy on preparations immunolabeled with anti-OPN antibodies. Staining patterns have also confirmed increased OPN expression, especially mannose rich isoforms showed an increase dependent on confluency and polarization in MDCK cells. The results were concluded that increased OPN expression during confluency and polarization in MDCK cells. The state of confluence and polarization have significant effects on the mannose rich OPN expression profile.
