Marketing Platform Strategy

Platforms have revolutionized the way we think about marketing and strategy. Further, the platform strategy is a growing area that has provided the business firms with mul tiple opportunities for generating value. Many firms are employing noticeably different tactics depending on whether they see a platform as a way to improve performance (by focusing on what they do best), grow their footprint (by leveraging capabilities that in the past they would have had to own), innovate (drawing on that vast majority of smart people who aren’t strictly in their employ), or capture more value. Platform thinking has thus revolutionized the way value is created and transferred. The business, which will survive in the modern era, should place a platform strategy as one of the key priority areas. It is not just enough to prioritize the platforms, but understanding that they can be integrated within a marketing strategy is very essential. Even though the study on plat- form strategy only focuses on digital platforms, this chapter provides a comprehensive overview of both digital and non-digital platforms and the strategic implications of both.
A Good Earthquake Concave Behaviour of a Seismic Isolator Which Supports a Metallic Roof

We combine some important theoretical mathematical results with practical aspects from engineering in a nice framework of -spiders, which forms a space with global nonpositive curvature. Some concavity properties into such framework are derived. As an application, we consider a mathematical model for an engineering problem. More precisely, we are trying to model the behaviour of tension forces appearing in a metallic roof supported on seismic isolators. In fact, we are looking to find the properties of good seismic isolators in order to reduce the destructive power of an earthquake. The answer consists of a concave behaviour in terms of the displacements on the 3D axes of the Cartesian system.
The Acquisition of a Complex Phonological Contrast: Voice Timing Patterns of English Initial Stops by Native French Speakers

Abstract This study examines the acquisition of the glottal and supra-glottal timing patterns of English initial stops by French speakers. French speakers have greater difficulty reducing the duration of glottal pulsing for English /bdg/ than producing long-lag voice onset time (VOT) and the concurrent reduction in closure duration for /ptk/. This is ascribed to the greater articulatory complexity of English /bdg/ for French speakers, the lower degree of perceptual salience of differences in glottal pulsing, compared to differences in VOT, the existence in English of a competing pattern of more fully voiced /bdg/, and the existence in French of aspirated contextual variants of the lingual stops before high vowels. The latter also explains why long-lag VOT is more difficult to acquire for the labial than for the lingual stops. Acquisition of English-like VOT appears to proceed from (1) positive transfer from French of long voicing lag for lingual stops in high vowel contexts, to (2) distributional extension to nonhigh vowel contexts and to the labial stop, and to (3) gradual stretching of the lag to better approximate the English norm. The acquisition of English-like voicing appears to proceed in a similar fashion.
Economic implications of climate change for infrastructure planning in transboundary water systems: An example from the Blue Nile

This research develops a hydroeconomic modeling framework for integrating climate change impacts into the problem of planning water resources infrastructure development. It then illustrates use of that framework in evaluation of two alternative sizes of a potential hydropower project along the Blue Nile in Ethiopia. Storing water in a Blue Nile reservoir provides an interesting case for testing this integrated approach because such a project would induce a number of physical and economic changes, both transboundary and climate‐dependent. The proposed framework makes two contributions to the existing literature on water resources project appraisal. First, it demonstrates how routinely used hydrological modeling techniques can be supplemented with Monte Carlo simulation to include economic uncertainties inherent in the planning problem, in addition to its more commonly considered physical dimensions. Second, it demonstrates how analysts can include a number of linkages between climate change, hydrology, and economic production in conventional planning models to develop better understanding of the complexities and important uncertainties associated with future conditions. While the framework described here has not been used in a full analysis of alternative development projects in the Blue Nile, the general approach could be combined with a variety of decision‐analytic tools to evaluate design and management alternatives in water resources systems.
GeoVis - From Terrain to Tweets and Movements

Spatial data exhibits an outstanding value in a broad range of application areas. Waldo Tobler’s first law of geography highlights the phenomenon of spatial autocorrelation: “Everything is related to everything, but near things are more related than distant things. ” In other words, the various properties of records of most data sources, such as meteorological data, health data, or even social media data, are frequently dependent variables of the spatial properties. It is thus no wonder that they also play an outstanding role in data visualization. If any feature can be visualized spatially, a visualization researcher will most probably implement a map view if he or she wants to find patterns, trends, and outliers in the data. Every visualization is based on placing graphical marks, such as points, lines, and areas with different properties, such as color, size, orientation, and shape into the so-called spatial substrate – the available space on the screen. Most of the features that can be perceived pre-attentively by a human observer relate to spatial position, spatial patterns, or the form of objects. Therefore, even if the data does not contain any spatial property, say a corpus of text documents, researchers still try to find means to visualize them in a spatial way. With a technique called multidimensional scaling, we can map text data into a two-dimensional pane such that near documents are more related than distant documents.
Constraining hydrostatic mass bias of galaxy clusters with high-resolution X-ray spectroscopy

Gas motions in galaxy clusters play important roles in determining the properties of the intracluster medium (ICM) and in the constraint of cosmological parameters via X-ray and Sunyaev-Zel'dovich effect observations of galaxy clusters. The Hitomi measurements of gas motions in the core of the Perseus Cluster have provided insights into the physics in galaxy clusters. The XARM mission, equipped with the Resolve X-ray micro-calorimeter, will continue Hitomi's legacy by measuring ICM motions through Doppler shifting and broadening of emission lines in a larger number of galaxy clusters, and at larger radii. In this work, we investigate how well we can measure bulk and turbulent gas motions in the ICM with XARM, by analyzing mock XARM simulations of galaxy clusters extracted from cosmological hydrodynamic simulations. We assess how photon counts, spectral fitting methods, multiphase ICM structure, deprojections, and region selection affect the measurements of gas motions. We first show that XARM is capable of recovering the underlying spherically averaged turbulent and bulk velocity profiles for dynamically relaxed clusters to within $\sim 50\%$ with a reasonable amount of photon counts in the X-ray emission lines. We also find that there are considerable azimuthal variations in the ICM velocities, where the velocities measured in a single azimuthal direction can significantly deviate from the true value even in dynamically relaxed systems. Such variation must be taken into account when interpreting data and developing observing strategies. We will discuss the prospect of using the upcoming XARM mission to measure non-thermal pressure and to correct for the hydrostatic mass bias of galaxy clusters. Our results are broadly applicable for future X-ray missions, such as Athena and Lynx.
Using centroid based nearest neighbor classifier in predicting small molecule activity

Small molecules, especially those which alter biological processes and disease states, are of significant interest. Predicting the specific bioactivities of small molecules is a general problem that has attracted particular attention. Nearest Neighbor(NN) classification is one of the most widely used methods for small molecule classification, but it suffers from both speed and overfitting. We propose a variation, namely Centroid based Nearest Neighbor (CBNN) classifier to solve NN problems, and a specific approach that we call Combinatorial Centroid Nearest Neighbor(CCNN) approach. We applied CCNN to a number of data sets, which are publicly available. It turned out that CCNN has the best accuracy and running time among all competitors.
Impediments, opportunities and strategies to enhance trade of wild and semi-wild food plants in Bunyoro- Kitara Kingdom, Uganda

This study examined the impediments, opportunities and strategies to enhance trade of wild and semi-wild food plants (WSWFPs) in Bunyoro-Kitara Kingdom, Uganda. Semi-structured questionnaire was administered face-to-face to sixty six (66) traders of WSWFPs in the formal markets: five (5) mobile hawkers and eleven (11) home-based/roadside traders. As a result of their small number, all traders that were found selling WSWFPs were interviewed. Data were analysed using simple descriptive statistics in excel spreadsheet and MINITAB statistical package. A number of challenges including high perishability, market dues, inaccurate consumers’ perceptions, seasonal shortfalls and unreliable supply, unorganized markets, little or no value addition, limited market information, and the inexistence of market promotional activities affected the trade in WSWFPs. However, the growing market demands, increasing focus of most service providers in creating awareness on WSWFPs, ever-changing perception on nutritional values of WSWFPs by the public, current government emphasis on value addition of traded agricultural products, little or no capital requirement for starting up trade in WSWFPs, and absence of restrictive regulations on sale of WSWFPs were regarded as good opportunities that could be exploited to enhance trade in WSWFPs. Key strategies for improved marketing WSWFPs included among other things, training gatherers and traders on value adding activities prior to sale, deliberate investment in promotional and awareness campaigns to expose the hidden benefits of WSWFPs, scrapping market dues levied on traders selling WSWFPs, helping gatherers and sellers to organise themselves to form viable supply and market groups, linking gatherers and sellers to good markets, as well as providing them with available market information. There is thus, a need for concerted efforts to implement some of these feasible marketing strategies to improve on the markets of WSWFPs in the kingdom. Key words: Wild edibles, wild food, semi-cultivated food, marketing wild food, Uganda.
Genetic variation in transferrin as a predictor for differentiation and evolution of caribou from eastern Canada

Polycrylamide gel electrophoresis was used to analyse tranferrrin variation in caribou populations from Manitoba, Ontario, Quebec/Labrador, and from Baffin Island, Northwest Territories in eastern Canada. The transferrin allele frequencies in these populations were compared with those previously reported for Canadian barren-ground caribou, Rangifer tarandus groenlandicus, Alaska caribou, R.t. grand, Peary caribou, R.t. pearyi, Svalbard reindeer, R.t. pla-tyrhynchus, and Eurasian tundra reindeer, R.t. tarandus. A total of twenty different alleles was detected in the analysed material, considerable genetic heterogeneity being detected among regions. Three alleles that were relatively common in caribou from Ontario, Manitoba and Quebec/Labrador, were not present in R.t. grand, R.t. pearyi, R.t. tarandus or R.t. platyrhynchus, and present only at very low frequencies 'm R.t. groenlandicus. These findings, together with genetic identity analyses, suggest that the caribou in Manitoba, Ontario, and Quebec/Labrador are mainly of the R.t. caribou type, and that little interbreeding has occurred with other subspecies. The large genetic distance in the transferrin locus between R.t. caribou and other subspecies of reindeer/caribou suggests that, during the Wisconsin glaciation the ancestral populations of R.t. caribou survived in a refugium different from that of the ancestral populations of the other subspecies. Significant genetic differences between Baffin Island caribou and all other populations were mainly due to the presence of one allele that was in high frequency in Baffin Island caribou, but that was absent, or present in very low frequencies, in all other reindeer/caribou populations. The genetic differences between Baffin Island caribou and the other subspecies were greater than the differences between several of the currently recognized subspecies.
OWNERSHIP STRUCTURE AND FIRM VALUES: EMPIRICAL STUDY ON INDONESIA MANUFACTURING

The companies listed in Indonesia Stock Exchange generally have an organizational structure that separates owners and management. This situation may create a confalict between the owners and the management. However if they share a common goal, it can increase the companies’ values. This research is aimed at identifying the influence of ownership structure (managerial, institutional, foreign, and central) on the prices to book values (PBV). Understanding of the ownership structure is important for the control of a company operation. This research uses secondary data; it is based on the annual financial reports of Indonesia Stock Exchange in 2009 – 2011. A purposive sampling technique is applied, and 32 companies are selected as the sample. The data are analyzed using multiple linear regression and descriptive statistics. The research results show that the ownership structure significantly influences the firms values: (1) the managerial ownership does not have a positive influence on firm value, (2) the institutional ownership has a positive and significant influence on firm vlue, (3) the foreign ownership has a positive and significant influence on firm value, (4) the concentrated ownership does not have a positive influence on firm value. This research is limited to only the ownership structure as the factors influence of firm value.
How do warmer and darker waters influence population dynamics in size-structured fish communities?

Changes associated with an increased water temperature due to global climate change have potentially large consequences for aquatic organisms. However, not only temperature but also the amount of precipitation is increasing. This increased precipitation leads to increased runoff from terrestrial ecosystems into lakes and coastal waters, introducing brown coloured humic substances containing dissolved organic carbon, leading to browner waters. This browning leads to a decrease of light in the water, which may reduce both primary production and visibility. The reduced visibility can, in turn, impact organisms dependent on light for e.g. feeding, mating, and predator evasion. Warmer and browner waters can influence aquatic ecosystems on several levels of biological organization: individuals, populations and communities. The impacts on fish populations and communities mostly arise from individual-level impacts and interactions. To understand how this works, knowledge of how food-dependent body growth and size-dependent food intake impact fish population and community dynamics is needed. Some of the separate impacts of warming and browning on fish are well studied on multiple organizational levels. It is known that both warming and browning can have considerable influences on both availability and uptake of resources in aquatic systems. This influence can have immediate impact on fish individuals and populations, but also shift competitive ability among individuals of different sizes. As a consequence, there may be changes in growth rates, mean body size, fish productivity and species composition in response to warming and browning. Climate change often results in both warmer and darker lakes. Still, the combination of warmer and darker water bodies on fish individuals, populations, and communities, have not been studied extensively. In combination, the various effects of warming and browning might even be more pronounced than individually. As fish populations and communities are important for both ecosystem function, and recreational and commercial fisheries, it is important to identify the knowledge gaps concerning the combined impact of an increase in temperature and browning. In this essay I identify big gaps in our current knowledge on the combined effects of temperature and browning on interacting fish individuals and populations. The knowledge arising from future studies on combined climate change effects on interacting fish species can, for example, be used to adapt current fisheries management strategies to a future climate characterized by warmer and darker lakes.
One-Cycle Control Strategy with Active Damping for AC-DC Matrix Converter

This study presents an input filter resonance mitigation method for an AC–DC matrix converter. This method combines the advantages of the one-cycle control strategy and the active damping technique. Unnecessary sensors are removed, and system cost is reduced by employing the grid-side input currents as feedback to damp out LC resonance. A model that includes the proposed method and the input filter is established with consideration of the delay caused by the actual controller. A zero-pole map is employed to analyze model stability and to investigate virtual resistor parameter design principles. Based on a double closed-loop control scheme, the one-cycle control strategy does not require any complex modulation index control. Thus, this strategy can be more easily implemented than traditional space vector-based methods. Experimental results demonstrate the veracity of theoretical analysis and the feasibility of the proposed approach.
The effect of graded levels of dietary threonine on nitrogen retention and structure of the small intestine in young pigs.

The effects of four levels of dietary threonine (Thr) on growth performance, N retention and structure of the small intestine were studied in pigs from 13 to 22 kg of body weight (BW). Four diets were formulated to contain 6.46, 7.43, 8.37 and 9.32 g Thr. Each diet was fed to six pigs for 19 days and N balance was determined at 15 kg BW. Tissue samples of the small intestine were taken for histological and histochemical measurements. In pigs fed Thr-deficient diet, N retention (g per day) was lower than on diets containing 7.43 and 9.32 g Thr per kg. Tunica mucosa thickness and number of goblet cells (in villi and/or in crypts) containing neutral mucins were smaller on Thrdeficient diet than on other diets. It can be assumed that the level of dietary Thr amounting about 7.4 g per kg covers the requirement of piglets from 10 to 25 kg for rapid growth and maximal N retention as well as for supporting gut barrier function.
Overlapping Community Discovery Algorithm Based on Local Extension

Detecting communities in social networks represents a significant task in understanding the structures and functions of networks. However, in real graphs vertices are often shared between communities, thus overlapping mining in the network community is more meaningful. In this paper, we propose an effective method for overlapping community discovery, which is to discover the initial core community and extend the core community until it reaches a stable condition. Through experiments on several real datasets, this method can effectively partition the overlapping communities.
Effective collision strengths for ground-state and 2s22p–2s2p2 fine-structure transitions in C ii

The ab initio R-matrix method is used to calculate effective collision strengths for electron-impact excitation of the boron-like ion C II. We consider the fine-structure forbidden 2 P o 1 / 2 - 2 P o 3 / 2 transition within the 2s 2 2p ground configuration as well as the 16 fine-structure transitions arising from excitation from the 2s 2 2p to the 2s2p 2 configuration. The 16 lowest LS target states are included in the calculation. Effective collision strengths are obtained by averaging the electron collision strengths over a Maxwellian distribution of electron velocities. Results are presented for electron temperatures in the range log T(K) = 3.0-5.5, appropriate for astrophysical applications. Good agreement with previous evaluations is obtained.
The effect of feeding primalac probiotics on growth performance and blood parameters of ostriches.

This study investigated the effect of feeding primalac probiotics on growth performance and some blood parameters of ostriches from hatch until 8 wk of age. A total of 48 day-old ostriches were randomly divided into 4 equal treatment groups: 1) Control group fed with a basal diet, 2) 0.035% Primalac group: a basal diet supplemented with 0.035% primalac probiotic, 3) 0.095 % Primalac group fed a basal diet supplemented with 0.095 % primalac probiotic and 4) 0.135% Primalac group fed a basal diet supplemented with 0.135 % primalac probiotic. The results showed that inclusion of the primalac probiotics added to the basal diet improved body weight, FCR and blood parameters (glucose, cholesterol, uric acid and urea) with the 0.135% Primalac group registering the highest body weight, lowest FCR and lowest amounts of blood cholesterol, uric acid and urea (all p<0.05).
Meet the need – the role of vocational education and training for the youth labour market

To fight negative trends in the youth labour market, policymakers around the world foster vocational education and training programmes (VET). We therefore investigate how the share of three upper secondary education programmes, i.e. general education, school-based VET, and dual VET, affect the labour market of 15-to24-year-olds. We complement the existing literature by analysing non-linear effects that might arise due to general equilibrium effects. Furthermore, we include ten labour market indicators for integration and job quality. To address unobserved heterogeneity across countries, we run ? xed effects regressions on unbalanced panel data of 35 countries from 2004 to 2014. We ? nd that school-based VET hinders youth labour market integration. In contrast, dual VET improves not only labour market integration but also job quality. However, the positive and negative effects of VET programmes diminish with increasing enrolment rates. Thus, policymakers should consider these different effects in their educational reforms.
Is There a Retirement-Consumption Puzzle? Evidence Using Subjective Retirement Expectations

Previous research finds a systematic decrease in consumption at retirement, a finding that is inconsistent with the life cycle/permanent income hypothesis if retirement is an expected event. In this paper, we use workers' subjective beliefs about their retirement dates as an instrument for retirement. After demonstrating that subjective retirement expectations are strong predictors of subsequent retirement decisions, we still find a consumption decline at retirement for workers who retire when expected. However, our estimates of this consumption fall are about a third less than those found when we instead rely on the instrumental variables strategy used in prior studies.
