Customer portfolio management in service firms: a comparison of theory and practice

Customer portfolio management can be of key importance to ensure profitability of the cus-tomer base in business-to-business relationships. Many customer portfolio approaches were conceptually developed for large and industrial firms that apply systematic customer manage-ment. However, scant research has empirically verified the practical use of portfolio models. This multiple case study of seven small firms in the search engine marketing sector primarily used exploratory interviews and secondarily company documents. The results lend support to the proposition that the complexity of the exchange and the fast-changing nature of the indus-try can influence customer management. More specifically, step-by-step or formal models for customer management − including the proposed criteria − are rarely applied and cover few issues that are relevant to service firms. Customer portfolio management is a highly context-dependent phenomenon in which informal methods are more important in highly complex service environments. The main practical implication is that formal systems can complement managerial judgment, in particular as the customer portfolio grows and more systems as well as procedures are required in the organization. Future research should investigate other ser-vice firms with varying types of services, while including several performance measures that can be related to the customer portfolio and the firm.
Coalburn catchment , northern England

The Coalburn research catchment (1.5 km 2 ) in Kielder Forest, Northern England, is a long-term project to study the effect of upland afforestation on hydrology. There is now a unique 45-year record; making it Britain’s longest running forest hydrology research catchment. The site was instrumented in 1967, ploughed and planted in 1972/73 and the trees have now reached maturity. Hourly meteorological data have been measured since 1993 and these have enabled hydrological simulations to be carried out using the Shetran model for the period 1993-2011. The results from this work show that after ploughing there was an increase of around 50-100 mm in annual streamflow compared with the original upland grassland vegetation. However, the mature trees now show a decrease of around 250-300 mm in the annual streamflow compared with the original vegetation and a decrease of around 350 mm in the annual streamflow compared with when the site was ploughed. The simulation results show very clearly the nonstationary nature of the catchment during 1993-2011 with an annual increase in intercepted evaporation and a decrease in discharge as the trees grow. Simulation results also show that peak discharges are higher for a cover of smaller trees compared with taller trees. However, the results suggest that the bigger the event the smaller is the difference, i.e. there is absolute convergence for the two different tree scenarios at
Noise and synchronization in chaotic neural networks

We show that two identical fully connected chaotic neural networks can always achieve a stochastic synchronization state when linked with a sufficiently large common noise. This is the case for both lowdimensional hyperchaos and high-dimensional spatiotemporal chaos. When the parameters of the two driven systems possess a tiny difference, weakly noise-induced synchronization is obtained. Unstable finite-precision synchronization of chaos with positive conditional Lyapunov exponent is also observed. It is caused by the on-off synchronizing intermittent dynamics. @S1063-651X~98! 10106-X#

Hetero CuOx/ZnO micro-/nanostructure: Carbothermal reduction–vapour phase transport

ZnO micro-/nanostructures were synthesized by the carbothermal reduction–chemical vapour transport method. This work is focused on the effect of the substrate temperature and Cu catalyst layer on the shape and geometry of ZnO micro-/nanostructures. The thermally oxidized Cu template affects the structure, chemical identity, optical and photoluminescence properties of the ZnO micro-/nanostructure and results in a CuO x /ZnO heterostructure. SEM studies give a direct evidence of the role of deposition temperature and Cu catalyst in the formation of a stable hemisphere based wire, a comb-like cantilever, a javelin-like tetrapod, a spherical and polyhedral cage of ZnO. XRD and Raman measurements confirm a hexagonal wurtzite structure of the ZnO micro-/nanostructure. The absorption edge of the ZnO/CuO x heterostructure is redshifted in comparison to the pure ZnO structure. PL studies indicate that the UV emission can be suppressed significantly while the green emission is enhanced due to the change in the morphology of ZnO micro-/nanostructures.
A methodology to plan, communicate and control multidisciplinary design processes

Architecture, Engineering, and Construction (AEC) projects require multidisciplinary solutions. To develop these solutions, AEC professionals need to construct their discipline specific information, but they also need to interrelate and make trade-offs with the information of other disciplines. Today AEC professionals have formal methods to construct much of their single discipline information: however, they lack formal methodologies to plan, communicate and control their multidisciplinary processes. As a result, AEC professionals struggle to design and execute good multidisciplinary solutions. By leveraging existing industry and our own methods and technology, we are designing and implementing such a formal methodology. Using this methodology, AEC professionals will collaboratively and iteratively define their objectives using our POP (Product, Organization, Process) method. They will develop options and analyze them using our Narrative method. They will decide upon options using our Decision Dashboard method. To develop this methodology, we are gathering test cases from ongoing AEC projects, implementing our methodology in the CIFE iRoom, re-enacting these test cases and conducting live charettes with our implemented methodology, and validating the extent to which this methodology enables AEC professionals to better communicate and control their multidisciplinary design processes. The scientific purpose of this research is to better formalize and manage design processes among many AEC professionals and their information. The practical purpose of this methodology is to enable AEC professionals to improve their multidisciplinary designs.
在 H . 264 / AVC 視訊上做資訊隱藏之研究及其應用 A Study on Data Hiding in H . 264 / AVC Videos and Its Applications 研 究 生:黃冠霖 Student :

With the advance of information technologies, more and more digital video applications on the internet have been proposed. H.264/AVC videos are used in a wide variety of applications. In this study, several methods for data hiding applications, namely, covert communication, copyright protection, and video sharing, are proposed using H.264/AVC videos as cover media. For covert communication, we propose a large-volume method and an optimal method for hiding secret data in H.264/AVC videos, based on the use of prediction modes and tree structured motion compensation. The optimal method is a tradeoff between hiding capacity, imperceptibility, and low bit rating. For copyright protection, in order to protect the ownership of downloaded videos at the client site, a method using a removable visible watermarking technique with a scheme for display control on specified computers is proposed. For the application of secret sharing, we share the data of the prediction modes of a secret video based on exclusive-OR operations and hide the resulting share data into the prediction modes of cover videos. The resulting share videos are then distributed to participants to keep. By collecting the share videos owned by all participants, the secret video can be recovered. Good experimental results show the feasibility of the proposed methods.
PR ] 1 2 M ar 2 01 8 On the first-passage area of a Lévy process

Let be X(t) = x−μt+σBt−Nt a Lévy process starting from x > 0, where μ ≥ 0, σ ≥ 0, Bt is a standard BM, and Nt is a homogeneous Poisson process with intensity θ > 0, starting from zero. We study the joint distribution of the first-passage time below zero, τ(x), and the first-passage area, A(x), swept out by X till the time τ(x). In particular, we establish differential-difference equations with outer conditions for the Laplace transforms of τ(x) and A(x), and for their joint moments. In a special case (μ = σ = 0), we show an algorithm to find recursively the moments E[τ(x)mA(x)n], for any integers m and n; moreover, we obtain the expected value of the time average of X till the time τ(x).
Analysis of Hantaviruses Glycoprotein Sequence Using SVM Algorithm

Hantaviruses are single-stranded, enveloped, negative sense RNA viruses of the Bunyaviridae family. They induce deadly hemorrhagic fever with fatality up to 40%. Currently, there is no specific cure for Hantaviruses, so more researches about this mortal virus should be done. In order to effectively analyze a variety of different Hantaviruses, we utilize a model called the support vector machine (also known as SVM) which is generally used for analyzing and classifying binary data.The basic mechanism of the SVM is to find the most optimal hyperplane, or the maximum-margin hyperplane, which can separate different types of data with the least error bound. Out of all of the hyperplanes that may be used to classify the data points, the most optimal hyperplane is the one that has the largest margin, or separation among different types of data. In other words, the optimal hyperplane is chosen in the case where the distance between the nearest points of each group of data is maximized. Ultimately, using the selected hyperplane, SVM classifies the data points and computes values such as accuracy and sensitivity. At the end of its operation, the SVM algorithm prints out the computed values. Such SVM algorithms can be used to learn the characteristics of each Hantavirus such as sequence patterns and abundance of amino acids. Since we are the first time to scientifically investigate the Hantavirus with SVM, it is expected that the results of this research will be greatly helpful for further in-depth researching and the development of the cure for the virus.

Do affluent urban consumers drive direct food sales in the Northeast United States? A three-part analysis.

The last century has seen steady decline in the number of farms and ever-worsening concentration of economic power in the food system. In more recent decades, agricultural sales directly to consumers have grown, raising questions about the role of economic privilege and its spatial distribution in supporting direct marketing. We address this question in a three-part analysis of 216 counties in nine Northeast states. First, we compare four direct-sales indicators and their common covariates among county types defined by metropolitan status and adjacency to metro/nonmetro borders. Second, we map four direct-sales variables over these county types. Third, we construct panel regression models with county as a fixed-effect in order to examine the influence of county-level household income on direct agricultural sales while controlling for other county-level variables shown to have an influence: population, vegetable production, farm size, and number of farms. Together, these three perspectives—bivariate, spatial, and multivariate—show that economic privilege is a a * Corresponding author: Amy Guptill, Department of Sociology, The College at Brockport, SUNY; 350 New Campus Drive; Brockport, NY 14420 USA; +1-585-395-5657; aguptill@brockport.edu b David A.

Landscape and vegetation in a military area - past and present

This paper presents current research in the former Ralsko military area (MA), which lies in the norther n part of Bohemia (Czech Republic). MA Ralsko was founded in 1951 and army training took place there until 1991. The whole area presents an interesting example of landscape evolution impac ted by strong socio-political movements. The landsc ape and its vegetation are studied from a historical point of v iew, where the history of the area, changes in land use and spontaneous vegetation succession are all observed together in order to gain an overall view, which will help in f orming a future management strategy. Our interest focuses on the no n-forested areas in the former MA Ralsko, especially on the former battle tank training grounds and the shooting range . These zones were originally an agricultural lands cape with scattered settlements, villages and one small town, inhabited by a mainly German population. Nowadays the outlines of the villages are still visible in the midst of the grassy area, because remnants of buildings offer good conditions for shrubby overgrowth and trees. A 16 km long transect was set in the are a of interest and six study sites were chosen along it, in the former villages. Small study areas were set up in and arou nd each village, and the current state of the veget ation has been documented. The study areas were chosen in accordance with historical land use in the village (residen tial area, meadows, orchards, ponds, etc.) The land use changes since 1 938 are studied from aerial photographs, and the an alyses are maintained in the Geographical Informational System (GIS).
“The Time of Unrememberable Being”: Wordsworth's Autobiography of the Imagination

Introduction Item. In October 1798, William Wordsworth finds himself isolated, with his sister, in a rented room in the German town of Goslar, during the coldest winter of the century. In a small notebook bound in boards, starting from the back among Dorothy's grammar notes, he begins the story of his childhood at Cockermouth and Hawkshead in the English Lake District. Returning to his earliest years, he suddenly pauses, and interjects, now I speak of things That have been & that are no gentle dreams Complacent fashioned fondly to adorn The time of unrememberable being The words stand for an instant. In a letter to Coleridge, he complains of "an uneasiness at my stomach and side, with a dull pain about my heart" (Wordsworth and Wordsworth 236). Returning to his bold assertion, he crosses out the line that, perhaps, protests too much, leaving only a hesitant disclaimer: perhaps I speak of things Complacent fashioned fondly to adorn The years of unrememberable being (MS JJ, Z r , Wordsworth, Prelude 1798-99 10, 114)
Weak-inertial flow between two rough surfaces

“Oseen–Poiseuille” equations are developed from an asymptotic formulation of the three-dimensional Navier–Stokes equations in order to study the influence of weak inertia on flows between rough surfaces. The impact of the first correction on macroscopic flow due to inertia has been determined by solving these equations numerically. From the numerical convergence of the asymptotic expansion to the three-dimensional Navier–Stokes flows, it is shown that, at the macroscopic scale, the quadratic correction to the Reynolds equation in the weak-inertial regime vanishes generalizing a similar result in porous media.
Comparison of Radial and Halbach Array PMLSM by Employing 2-D Electromagnetic Finite Element Analysis

ARTICLE HISTORY: Received 03 September 2016 Revised 25 November 2016 Accepted 26 November 2016 The replacement of steam catapults with electromagnetic ones is becoming an overwhelming trend in aircraft launch systems. The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has many advantages such as high thrust, good controllability, etc. As a launching motor, a double-sided plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper compares two PM mover with quasi-Halbach array topology and radial topology for PMLSM application. A detailed analytical modeling based on Maxwell equations is presented for analysis and design of PMLSM with Halbach array. Finally, 2-D non-linear time-stepping transient finite element method is employed to demonstrate validity of the theoretical analysis and parametric search. Using FEA, the effects of the parameters on the thrust amplitude are analyzed. Finally, A design optimization method is applied to PMLSM with Halbach array. The obtained results form 2-D FEM show the increase of thrust force and flux density distribution in the air gap.
Morphisms between Cremona groups, and characterization of rational varieties

Abstract We classify all (abstract) homomorphisms from the group $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}{\sf PGL}_{r+1}(\mathbf{C})$ to the group ${\sf Bir}(M)$ of birational transformations of a complex projective variety $M$, provided that $r\geq \dim _\mathbf{C}(M)$. As a byproduct, we show that: (i) ${\sf Bir}(\mathbb{P}^n_\mathbf{C})$ is isomorphic, as an abstract group, to ${\sf Bir}(\mathbb{P}^m_\mathbf{C})$ if and only if $n=m$; and (ii) $M$ is rational if and only if ${\sf PGL}_{\dim (M)+1}(\mathbf{C})$ embeds as a subgroup of ${\sf Bir}(M)$.
STRESS INTERACTION BETWEEN THRUST FAULTS ALONG THE SW HELLENIC ARC (GREECE)

The occurrence of strong earthquakes (M>6.3) and the evolution of the stress field along the southwestern part of the Hellenic arc since 1959 are examined by the cal­ culation of Coulomb stress changes. The study area is characterized by low angle thrust faults and high seismicity as being part of the subduction interface. Coulomb stress changes were calculated assuming that earthquakes can be modeled as static dislocations in an elastic half-space, considering the co-seismic slip during strong events and the slow tectonic stress build-up along major fault segments due to the movements of the tectonic plates. The ruptures are modeled taking into account the strike, dip, and rake appropriate to each event examined. It is evaluated whether the stress changes brought a given earthquake closer to, or farther away from, failure. It was found that the majority of the events (strong and smaller) are located in stress enhanced areas.
Mechanisms of rDNA silencing and the Nucleolar Remodelling Complex (NoRC)

Protein synthesis in living cells requires functional ribosomes which are composed of ribosomal proteins and ribosomal RNA (rRNA) molecules. rRNA is transcribed from tandemly repeated ribosomal DNA (rDNA) which is organised into a nuclear compartment termed the nucleolus in S-phase cells. It is essential that rDNA transcription is properly regulated in order to meet the cell's requirements for ribosomes and hence protein synthesis without wasting metabolic energy. In the last twenty years many proteins involved in regulating this process have been identified, suggesting that most organisms contain multiple protein complexes that regulate rDNA packaging and transcription. Importantly, it has become clear that errors in the function of these proteins can permit aberrant cellular growth, including in several classes of cancer. In this review, I discuss the history of how protein complexes such as the Nucleolar Remodelling Complex (NoRC) were discovered, using examples from humans and from model research organisms from different biological groups. I will discuss recent discoveries of the critical roles of rDNA-binding complexes in nucleolar assembly, the widespread occurrence of regulatory non-coding RNAs which interact with these complexes, and the pathways which regulate rDNA transcription in response to cellular energy status. Finally, I will review the growing evidence that misregulation of rDNA transcription not only allows the growth of cancerous cells, but can trigger oncogenesis itself.
A novel natural insecticide molecule for grain protection

We have isolated a novel bioactive molecule from the roots of Decalepis hamiltonii that shows insecticidal properties against the stored-product insects Sitophilus oryzae, Rhyzopertha dominica and Callosobruchus chinensis by contact bioassay (LC 50 : 0.033-0.044 mg/cm 2 ). This compound proved effective as a grain protectant against stored product insects of wheat and green gram. The compound is a novel insecticidal molecule and a promising grain protectant of natural origin.
