A Critical Review of Theories Underlying Relationship Marketing in the Context of Explaining Consumer Relationships

Knowledge on relationship marketing, particularly as it applies to consumer relationships, is still in its early stages of development. Relationship marketing approaches draw on different underlying theories, depart from different units of analysis, and often focus on issues at different levels of aggregation. A clearer understanding of the theoretical underpinnings of relationship marketing would benefit its further theoretical development and guide empirical research. This article provides a description of the characteristics, strengths, and weaknesses of seven theories lying at the core of relationship marketing. Based upon this description, we illustrate how the theories can be used to determine the relative relationship friendliness of a consumer exchange situation. This should enable researchers to assess the added value of each theory to the particular consumer exchange situation that they are investigating.

Schizosaccharomyces pombe Arc3 is a conserved subunit of the Arp2/3 complex required for polarity, actin organization, and endocytosis

We characterized the Schizosaccharomyces pombe arc3 gene, whose product shares sequence homology with that of the budding yeast ARC18 and human ARPC3/p21 subunits of the Arp2/3 complex. Our data showed that Arc3p co‐localizes with F‐actin patches at the cell ends, but not with F‐actin cables or the equatorial actin ring, and binds other subunits of the Arp2/3 complex. Gene deletion analysis showed that arc3 is essential for viability. When arc3 expression was repressed, F‐actin patches became dispersed throughout the cell with greatly reduced mobility. Furthermore, in arc3‐repressed cells, endocytosis was also inhibited. Human ARPC3 rescued the viability of the Sz. pombe arc3 null mutant; in addition, ARPC3 also localized to F‐actin patches in human cells. These data suggest that Arc3p is an evolutionarily conserved subunit of the Arp2/3 complex required for proper F‐actin organization and efficient endocytosis. Copyright © 2011 John Wiley & Sons, Ltd.
A 40 nm CMOS T/H-less flash-like stroboscopic ADC with 23dB THD and >50 GHz effective resolution bandwidth

We propose a track-and-hold-less flash-like stroboscopic ADC for use in the implementation of an undersampling ultra-wide-band radar receiver. The ADC is comprised of a number of sub-ADCs in which each sub-ADC is a multi-pass ADC. Strong-Arm latch with tens of GHz of sampling bandwidth is utilized as the core of each multi-pass ADC. The prototype of the ADC achieves a THD of ∼23dB with a THD ERBW of > 50 GHz when the input signal swing is ∼135 mVpp. The total power consumption of the prototype is ∼10 mW when it is operated under a 1 GHz clock giving it an FOM of ∼0.87 pJ/cs.
Some Neglected Criteria in the Selection of Materials for Mentally Retarded Pupils

The Problem of AbstractionKeep it Concrete • The selection of materials for retarded pupils presents some unique problems besides those inherent in choosing any teaching materials. Special care must be taken in choosing the proper level of difficulty, in terms of both concepts and vocabulary. As motivation is often a problem among the retarded, the interest level of the material must be correspondingly high. Continuous requests for such high-interest, low-vocabulary material come from teachers visiting the various Instructional Materials Centers throughout the country. In some cases, the district-developed course of study for the retarded classes is less adequate than the one designed for teachers of regular classes, or may even be nonexistent. Occasionally, the special class teacher may be expected to take major responsibility for the selection and acquisition of materials, without time to confer with teacher colleagues. There are not always consultants available. Where budgets for special class material are adequate, the problem is compounded. The teacher may then be bewildered by the variety of material available from various publishers and manufacturers. It is the purpose of this article to present three criteria for the selection of materials for the retarded which may be overlooked under the pressure of adding material which is appropriately paced for the class involved. These criteria are based on the assumptions that the retarded child has problems dealing in abstractions, a poorly developed sense of taste and aesthetics, and difficulty in transferring learning from the classroom to other applicable situations. In order to deal with these characteristics of the retarded child, the teacher should choose instructional materials that are as concrete, beautiful, and real as possible. o The types of learning which we demand of our school children are becoming increasingly abstract, presumably in response to the increasingly rigorous demands of our technology. The impact of the "new math" is already well known. Science education is also moving rapidly towards the teaching of concepts, with a subsequent decrease in the need for rote memorization of data. The emphasis in education is on big ideas which can present a picture of our constantly changing universe. The English language, too, is beginning to shed its rigid rules of grammar, and study is concentrated on the structure of language and the nature of communication. Even in the area of social studies, the emphasis is on implementing programs which stress the conceptual over the merely factual. Where does this leave the retarded pupil? Simply stated, the present curri,cular developments are likely to leave him farther behind than ever as more attention is drawn to his limited ability to grasp and retain abstract materials. Work by developmental psychologists such as Piaget (1954) points up the con-
A Fast Algorithm for Simulating Multiphase Flows Through Periodic Geometries of Arbitrary Shape

This paper presents a new boundary integral equation (BIE) method for simulating particulate and multiphase flows through periodic channels of arbitrary smooth shape in two dimensions. The authors consider a particular system---multiple vesicles suspended in a periodic channel of arbitrary shape---to describe the numerical method and test its performance. Rather than relying on the periodic Green's function as classical BIE methods do, the method combines the free-space Green's function with a small auxiliary basis, and imposes periodicity as an extra linear condition. As a result, we can exploit existing free-space solver libraries, quadratures, and fast algorithms, and handle a large number of vesicles in a geometrically complex channel. Spectral accuracy in space is achieved using the periodic trapezoid rule and product quadratures, while a first-order semi-implicit scheme evolves particles by treating the vesicle-channel interactions explicitly. New constraint-correction formulas are introduced that preserve reduced areas of vesicles, independent of the number of time steps taken. By using two types of fast algorithms, (i) the fast multipole method (FMM) for the computation of the vesicle-vesicle and the vesicle-channel hydrodynamic interaction, and (ii) a fast direct solver for the BIE on the fixed channel geometry, the computational cost is reduced to $O(N)$ per time step where $N$ is the spatial discretization size. Moreover, the direct solver inverts the wall BIE operator at $t = 0$, stores its compressed representation and applies it at every time step to evolve the vesicle positions, leading to dramatic cost savings compared to classical approaches. Numerical experiments illustrate that a simulation with $N=128, 000$ can be evolved in less than a minute per time step on a laptop.

Lyapunov and other spectra : a survey ∗

Motivated by the basic problem of studying stability of nonautonomous linear systems, different definitions of spectra have been proposed over the years. We review some of these definitions, paying particular attention to how the spectra may be computed. Since the spectra are given by intervals of the real line, one would like to compute the endpoints of these intervals. As it turns out, these endpoints may coincide with the Lyapunov exponents (LEs) of the system. For this reason, we will review computational methods which have been used to approximate the LEs.
How powerful are the DDH hard groups?

The question whether Identity-Based Encryption (IBE) can be based on the Decisional DiffieHellman (DDH) assumption is one of the most prominent questions in Cryptography related to DDH. We study limitations on the use of the DDH assumption in cryptographic constructions, and show that it is impossible to construct a secure Identity-Based Encryption system using, in a black box way, only the DDH (or similar) assumption about a group. Our impossibility result is set in the generic groups model, where we describe an attack on any IBE construction that relies on oracle access to the group operation of randomly labelled group elements – a model that formalizes naturally DDH hardness. The vast majority of existing separation results typically give separation from general primitives, whereas we separate a primitive from a class of number theoretic hardness assumptions. Accordingly, we face challenges in creating an attack algorithm that will work against constructions which leverage the underlying algebraic structure of the group. In fact, we know that this algebraic structure is powerful enough to provide generic constructions for several powerful primitives including oblivious transfer and chosen ciphertext secure public-key cryptosystems (note that an IBE generalizes such systems). Technically, we explore statistical properties of the group algebra associated with a DDH oracle, which can be of independent interest.
Acoustic feature compensation based on decomposition of speech and noise for ASR in noisy environments

This paper presents a set of acoustic feature pre–processing techniques that are applied to improving automatic speech recognition (ASR) performance on the Aurora 2 noisy speech recognition task. The principal contribution of this paper is an approach for cepstrum domain feature compensation in ASR which is motivated by techniques for decomposing speech and noise that were originally developed for noisy speech enhancement. This approach is applied in combination with other feature compensation algorithms to compensating ASR features obtained from a mel–filterbank cepstrum coefficient (MFCC) front–end. Performance comparisons are made with respect to the application of the minimum mean squared error log spectral amplitude estimator (MMSE–LSA) based speech enhancement algorithm prior to feature analysis. An experimental study is presented where the feature compensation approaches described in the paper are found to reduce ASR word error rate by as much as 31% relative to uncompensated features under simulated environmental and channel mismatched conditions.
Determination of the potential gold electrowinning from an ammoniacal thiosulphate solution applied to recycling of printed circuit board scraps

The use of electrochemical techniques in the selective recovery of gold from a solution containing thiosulphate, ammonia, and copper, obtained from the leaching of printed circuit boards from mobile phones using ammoniacal thiosulphate, are shown in this work. First, cyclic voltammetry tests were performed to determine the potential of electrodeposition of gold and copper, and then, electrowinning tests at different potentials for checking the rates of recovery of these metals were performed. The results of the cyclic voltammetry show that copper deposition occurs at potentials more negative than −600 mV (Ag/AgCl), whereas the gold deposition can be performed at potentials more positives than −600 mV (Ag/AgCl). The results of electrowinning show that 99% of the gold present in solutions containing thiosulphate and copper can be selectively recovered in a potential range between −400 mV (vs Ag/AgCl) and −500 mV (vs Ag/AgCl). Furthermore, 99% of copper can be recovered in potentials more negative than −700 mV (vs Ag/AgCl).
The Hand of the Past in Contemporary Southern Politics

A central story of contemporary southern politics is the emergence of Republican majorities in the region's congressional delegation. Acknowledging the significance and scope of the political change, James M. Glaser argues that, nevertheless, strands of continuity affect the practice of campaign politics in important ways. Strong southern tradition underlies the strategies pursued by the candidates, their presentational styles, and the psychology of their campaigns. The author offers eyewitness accounts of recent congressional campaigns in Texas, Mississippi, Virginia, North Carolina, and South Carolina. In the tradition of his award-winning book Race, Campaign Politics, and the Realignment in the South, Glaser captures the "stuff" of politics - the characters, the images, the rhetoric, and the scenery. Painting a full and fascinating picture of what it is like on the campaign trail, Glaser provides wide-ranging insights into the ways that the "hand of the past" reaches into the southern present.
Automatic slide assignation for language model adaptation Applications of Computational Linguistics

Online multimedia repositories are rapidly growing and imposing themselves as fundamental knowledge assets. This is particularly true in the area of education, where large repositories of video lectures are being built, making education accessible to a wide community of potential students. As with many other repositories, most lectures are not transcribed because of the lack of efficient solutions to obtain them at a reasonable level of accuracy. However, transcription of video lectures is clearly necessary to make them more accessible. Also, this would facilitate lecture searchability and analysis, including classification, summarisation, or plagiarism detection. In addition, people with hearing disabilities would be able to follow the lectures just by reading the transcriptions. Manual transcription of these repositories is excessively expensive and time-consuming and current state-of-the-art automatic speech recognition (ASR) has not yet demonstrated its potential to provide acceptable transcriptions on large-scale collections of audiovisual objects.
Detecting and Changing Brain Waves Using Sound Wave Interception

Currently, a lot of people complain from stress and tension and require a device or method for stress relief. At the same time, similar problems of people not being able to make their mind active and feel lazy and bored to do tasks have also been found. Recently, the research for a system that is able to obtain the relaxation effect has been actively performed. For example, in a system where the user is presented with various sounds, the relaxation effect is measured from the brainwaves, heartbeat, and so on. Thus it was proved to be possible to change the state of brain by providing sound input to the users. In this research, we aim to construct a system to adjust the automatic operation of providing the necessary sound to obtain the required state of brain depending on users’ current state of brain. The appropriate sounds will be provided by detecting the brain waves and calculating the appropriate sound frequency to provide the user to change their state of mind. The forthcoming effects on the brain waves will then be analyzed and the sound input to user will be varied so as to send the brain to the required state.
eQuus: A Provably Robust and Locality-Aware Peer-to-Peer System

Peer-to-peer systems (p2p) are highly dynamic in nature. They may consist of millions of peers joining only for a limited period of time, resulting in hundreds of join and leave events per second. In this paper we introduce eQuus, a novel distributed hash table (DHT) suitable for highly dynamic environments. eQuus guarantees that lookups are always fast - in terms of both the delay and the total number of routing hops -, although peers may join and leave the network at any time and concurrently
Longitudinal associations between executive control and developing mathematical competence in preschool boys and girls.

Executive control (EC) is related to mathematics performance in middle childhood. However, little is known regarding how EC and informal numeracy differentially support mathematics skill acquisition in preschoolers. A sample of preschoolers (115 girls, 113 boys), stratified by social risk, completed an EC task battery at 3 years, informal numeracy assessments at 3.75 and 4.5 years, and a broad mathematics assessment during kindergarten. Strong associations were observed between latent EC at age 3 and mathematics achievement in kindergarten, which remained robust after accounting for earlier informal numeracy, socioeconomic status, language and processing speed. Relations between EC and mathematics achievement were stronger in girls than in boys. Findings highlight the unique role of EC in predicting which children may have difficulty transitioning to formal mathematics instruction.
Pointing with fingers, hands and arms for wearable computing

Pointing is a fundamental enabling operation for human-computer interaction across a broad spectrum of scenarios. The paper presents a study exploring how to develop a pointing system for truly wearable, rather than hand-held, computing. It describes a Fitts' law study of pointing based on motions in free-space captured using an inertial sensor pack. It compares performance when the pack is held in the hand, mounted on the back of the hand and finally on the wrist. The results show a significant, but numerically small, advantage in using the hands over using the upper arm only. This suggests that for wearable tasks where pointing is relatively infrequent a wrist based sensor pack may well be sufficient to enable effective and usable interaction.
Mycobacterium bovis subsp. caprae Caused One-Third of Human M. bovis-Associated Tuberculosis Cases Reported in Germany between 1999 and 2001

ABSTRACT The prevalence of the Mycobacterium bovis subsp. caprae and M. bovis subsp. bovis among German tuberculosis cases caused by the bovine tubercle bacillus from 1999 to 2001 was determined. Isolates from 166 patients living in Germany and 10 animals were analyzed by conventional laboratory procedures, spoligotyping, and partly by PCR-restriction fragment length polymorphism analysis of the gyrB gene. By spoligotyping, 55 of 176 isolates (31%) could be identified as M. bovis subsp. caprae, and 121 (69%) were confirmed as M. bovis subsp. bovis. In general, a low variability of spoligotypes with 59 distinct patterns and a cluster rate of 77% (136 isolates/19 clusters) was determined. About half of all isolates were grouped in the three main clusters with 29, 30, and 35 isolates, respectively. Differences in age and gender between the patient groups infected with M. bovis subsp. bovis and M. bovis subsp. caprae did not reach statistical significance. However, marked differences in the geographical prevalence of M. bovis subsp. caprae were observed, ranging from fewer than 10% of all M. bovis isolates in the north up to more than 80% of isolates in the south of Germany. In conclusion, M. bovis subsp. caprae accounts for a high ratio of human M. bovis-associated tuberculosis cases in Germany and was more frequently found in the southern part.
Measurement of Blood Flow in an Intracranial Artery Bypass From the Internal Maxillary Artery by Intraoperative Duplex Sonography

This study explored the hemodynamic characteristics of a subcranial–intracranial bypass from the internal maxillary artery by measuring blood flow on intraoperative duplex sonography. The hemodynamic parameters of the internal maxillary artery (n = 20), radial artery (n = 20), internal maxillary artery–middle cerebral artery bypass (n = 42), and internal maxillary artery–posterior cerebral artery bypass (n = 9) were measured by intraoperative duplex sonography. There was no significant difference in the internal diameters of the internal maxillary and radial arteries (mean ± SD, 2.51 ± 0.34 versus 2.56 ± 0.22 mm; P = .648). The mean radial artery graft length for subcranial–intracranial bypasses was 88.5 ± 12.78 mm (95% confidence interval [CI], 80.8–90.2 mm). Internal maxillary artery–middle cerebral artery bypasses required a shorter radial artery graft than internal maxillary artery–posterior cerebral artery bypasses (77.8 ± 2.47 versus 104.8 ± 4.77 mm; P = .001). The mean flow volumes were 85.3 ± 18.5 mL/min (95% CI, 76.6–93.9 mL/min) for the internal maxillary artery, 72.6 ± 26.4 mL/min (95% CI, 64.3–80.9 mL/min) for internal maxillary artery–middle cerebral artery bypasses, and 45.4 ± 6.7 mL/min (95% CI, 40.7–50.0 mL/min) for internal maxillary artery–posterior cerebral artery bypasses. All grafts were opened after the success of the salvage procedures had been established, and the early patency rates (1 month after the operation) were 95% for internal maxillary artery–middle cerebral artery bypasses and 100% the internal maxillary artery–posterior cerebral artery bypasses. Measurement of blood flow by intraoperative sonography can be helpful in decision making and predicting graft patency and success after neurosurgical bypass procedures.
Deriving service variants from business process specifications

Software service organizations typically tend to develop custom solutions upon entry to a project engagement. This is not a scalable proposition. Today, driven by the need for enhancing profitability, reuse of existing assets across customer engagements is a more viable strategy. This is leading to the transformation of software services organizations from a labor-based to an asset-based model. In the enterprise application development domain, business processes are used to model the dynamic behavior of enterprise applications. Hence one highly prevalent asset-based approach in this domain is to build a scalable portfolio of services using a service-oriented architecture (SOA) approach. This provides a mechanism for representing business processes as a set of business-aligned, loosely-coupled services that can be iteratively composed and re-composed to create loosely coupled composite applications that mirror and support business processes. A key research problem that arises here is how to instantiate a stated business process specification as a combination of variants of existing services in the portfolio. We show via an illustrative example that this problem is non-trivial and scalable, and it depends on the semantics of the business process specification, especially with respect to the inter-service data and control flow dependencies that the instantiated business process specification has to satisfy. To that end, we also present our Variation-Oriented Service Design (VOSD) algorithm for automatically deriving service-level variants from the stated business process specifications. We also show that our algorithm is scalable, since its asymptotic complexity is linear in the number of service variants. We also illustrate our algorithm via the example.
