Customer Relationship Management and Knowledge Discovery in Database

Customer relationships are increasingly central to business success (Kotler, 1997; Reichheld & Sasser, 1990). Acquiring new customers is five to seven times costlier than retaining existing customers (Kotler, 1997). Simply by reducing customer defections by 5%, a company can improve profits by 25% to 85% (Reichheld & Sasser, 1990). Relationship marketing—getting to know customers intimately by understanding their preferences—has emerged as a key business strategy for customer retention (Dyche, 2002). Internet and related technologies offer amazing possibilities for creating and sustaining ideal customer relationships (Goodhue, Wixom, & Watson, 2002; Ives, 1990; Moorman, Zaltman, & Deshpande, 1992). Internet is not only an important and convenient new channel for promotion, transactions, and business process coordination; it is also a source of customer data (Shaw, Subramaniam, Tan, & Welge, 2001). Huge customer data warehouses are being created using advanced database technologies (Fayyad, PiatetskyShapiro, & Smyth, 1996). Customer data warehouses by themselves offer no competitive advantages: insightful customer knowledge must be extracted from such data (Kim, Kim, & Lee, 2002). Valuable marketing insights about customer characteristics and their purchase patterns, however, are often hidden and untapped (Shaw et al., 2001). Data mining and knowledge discovery in databases (KDD) facilitate extraction of valuable knowledge from rapidly growing volumes of data (Mackinnon, 1999; Fayyad et al., 1996). This article provides a brief review of customer relationship issues. The article focuses on: (1) customer relationship management (CRM) technologies, (2) KDD techniques, and (3) Key CRM-KDD linkages in terms of relationship marketing. The article concludes with the observations about the state-of-the-art and future directions. Background
Why Be Diurnal? Or, Why Not Be Cathemeral?

As a behavioural strategy, cathemerality is thought to confer considerable advantages by allowing animals to extend activity flexibly into either the diurnal or nocturnal phase in response to the prevailing ecological conditions. Factors such as temperature, access to food sources and minimising the risk of predation are all thought to be important in promoting cathemerality, although previous studies have produced inconsistent results. This paper adopts a different approach by first asking whether an obligate diurnal species, the chacma baboon (Papio hamadryas ursinus), exhibits seasonal variation in behavioural flexibility in response to annual cycles of day length. While short day lengths are an important constraint on the activity of the baboons at De Hoop Nature Reserve, South Africa, long summer days permit considerable flexibility in thermoregulatory response, diet selection and patterns of habitat choice. Given that baboons adapt flexibly in response to a relaxation of time constraints, the question thus arises as to why diurnal and nocturnal primates do not adopt cathemeral activity patterns when time is constrained? For baboons, the costs of predation appear to prohibit exploitation of the nocturnal phase and it is likely that such constraints are true of most primates. It thus follows that Madagascar’s predatory environment must in some way permit or select for a cathemeral lifestyle. The importance of the predation by fossa (Cryptoprocta ferox) on the evolution of cathemerality is discussed.
Molecular Diversity Analysis in Potato (Solanum tuberosum L.) through RAPD Markers

Random Amplified Polymorphic DNA (RAPD) markers were used to study the molecular diversity of 12 popular potato varieties in Bangladesh. DNA was extracted from tender leaf sample for PCR amplification. The PCR amplified DNA profile was visualized on 2% agarose gel, staining with ethidium bromide. Eight RAPD primers were used to evaluate the genetic diversity of potato varieties. Some total of 36 DNA fragments were amplified and out of them 24 were polymorphic. Those primers generated 61.53% of polymorphic DNA band. The primer OPX 04 produced highest (9) number of DNA band and out of 9 amplicon 6 were polymorphic. Lowest number of amplification was observed in the primer OPA-17 and it was only 3. The highest Nei’s genetic distance (0.9701) was noticed between the variety Granola and Provinto. The highest (0.8205) number of genetic identity/similarity was observed between the varieties Cardinal and Diamant. The unweighted pair group method of arithmetic mean (UPGMA) dendrogram based on Nei’s genetic distance revealed that the 12 varieties followed into two main clusters. The present finding showed that there was high level of genetic diversity among the varieties which can be used for parental selection in potato breeding program.

Thermal-Electric Rating Method for Mass-Impregnated Paper-Insulated HVDC Cable Circuits

Compared to conventional ac cables, the current rating of HVDC cable circuits is more complicated because the permissible current is not only limited by the operating temperature, but also by the electrical stress within the insulation. Therefore the IEC60287 current rating standard is considered insufficient for some HVDC applications because it fails to include the stress limitation. This paper presents an analytical methodology to calculate an electrical stress-limited rating for HVDC cables, which considers the maximum dielectric stress as the current limiting factor. This paper represents the first part of a project which has comprehensively reviewed cable rating calculations for mass impregnated HVDC cable systems.
An Exploratory Study on the Distribution for The Results of IT-Enabled Value Co-Creation

This paper proposes to discover the phenomenon from an existing online user-generated platform to understand the issue on distributing the results from the Information Technology (IT)-enabled value collaboration. The main purpose is to fill up the gap that there is no method to make sure the distribution fairly to find an impartial way on distributing the result of the value collaboration works. This study explores the interaction among the three main stakeholders from the platforms in holistic perspective. It is expected that this paper will help people know the importance of distribution on final value from co-creation and help the platforms of co-creation improve their performance of collaboration by identifying the participants’ true needs or benefits to design a better environment for the next cooperation works.
Attack on a chaos-based “true” random bit generator

This paper presents an algebraic attack on a chaos-based “true” random bit generator (RBG). A clone system is proposed to analyze the security weaknesses of the RBG and its convergence is proved using master slave synchronization scheme. Secret parameters of the RBG are revealed where the only information available are the structure of the RBG and a scalar time series observed from the chaotic oscillator. Simulation and numerical results verifying the feasibility of the clone system are given. The RBG doesn't fulfill Diehard and NIST-800-22 statistical test suites, not only the next bit but also the same output bit stream of the RBG can be reproduced.
The relative value of CD4 cell count and quantitative HIV-1 RNA in predicting survival in HIV-1-infected women: results of the women's interagency HIV study.

OBJECTIVES To determine factors associated with survival and to assess the relative strength of CD4 cell count and HIV-1 RNA in predicting survival in a cohort of HIV-1-infected women. DESIGN Prospective cohort, enrolled during 1994-1995, with median follow-up of 29 months RESULTS Of 1769 HIV-infected women 252 died. In multivariate analyses, lower CD4 cell count, higher quantitative plasma HIV-1 RNA, and the presence of a self-reported AIDS-defining (Class C) condition were significantly associated with shorter survival: the relative hazard (RH) of dying was 1.17, 3.27, and 8.46, respectively for women with baseline CD4 cell count of 200-349, 50-199, and < 50 x 10(6) cells/l, compared with women with CD4 cell count of > or = 350 x 10(6) cells/l. Compared with women with HIV-1 RNA levels of < 4000 copies/ml plasma, the RH of dying for women with baseline quantitative HIV-1 RNA measurements of 4000-20,000, 20,000-100,000, 100,000-500,000 and > 500,000 copies/ml, was 2.19, 2.17, 3.16, and 7.25, respectively. CD4 cell count had as strong a prognostic value as HIV-1 RNA level, particularly among participants with more advanced immunodeficiency. When the analysis was adjusted to eliminate the distortion created by having disproportionately sized strata of the categorized variables, the relative hazard of death associated with CD4 cell count became even larger in comparison with that for HIV-1 RNA. Eliminating from the analysis all follow-up time during which participants could have received highly active antiretroviral therapy did not change these findings. Age was not a predictor of survival after adjustment for covariates. CONCLUSIONS CD4 cell count and HIV-1 RNA had similar prognostic value in this cohort of HIV-1-infected women. Even in the presence of a low viral burden, a substantially decreased CD4 cell count remained a strong predictor of mortality.
Improvement of Persian Spam Filtering by Game Theory

There are different methods for dealing with spams; however, since spammers continuously use tricks to defeat the proposed methods, hence, filters should be constantly updated. In this study, Stackelberg game was used to produce a dynamic filter and the relations between filter and adversary were modelled as a turn game in which there is a leader and a follower. Then, an attempt was made to solve the game as an optimization program via the evolutionary stable strategy (ESS). The dataset used in the study for evaluating and analyzing the proposed method was a real dataset including the emails of four users’ personal emails. The results of the conducted evaluations and investigations indicated that the proposed method had an 8% improvement over the three-class classification method and a 0.8% improvement over the ESS-based equilibrium point method
A topical combination of rapamycin and tacrolimus for the treatment of angiofibroma due to tuberous sclerosis complex (TSC): a pilot study of nine Japanese patients with TSC of different disease severity

Background Dysregulation of mTOR signalling by mutations in tuberin and/or hamartin leads to the formation of tuberous sclerosis complex (TSC). Trials to treat TSC using mTOR inhibitors, including rapamycin, have been performed. Although rapamycin improves many TSC lesions, significant side‐effects appear after systemic administration. Topical administration has been recommended.
Variations in Hospital Waste Quantities and Generation Rates

Abstract The relationship between public health and improper collection, handling, and disposal of solid wastes in general, and hospital wastes in particular, is quite clear. Hazardous and nonhazardous wastes generated from different divisions of two of the largest public hospitals (capacity of approximately 400 beds each) in Kuwait were quantified and generation rates were determined. The generation rates were related to some important factors such as the number of patients, number of beds, and the type of activity conducted in different sections of the hospitals. The relationship between the waste generation rate and the number of patients was more applicable than that expressed in terms of the number of beds. The rates observed were in the range of 4.89 to 5.4 kg/patient/day, which corresponds to 3.65 to 3.97 kg/bed/day, respectively. These generation rates were comparable with those reported in the literature for similar hospitals. Minimal waste quantities were collected in the weekends. The study indicated that the hospitals surveyed provide some segregation of hazardous and nonhazardous wastes. Hazardous wastes contributed about 53% of the total quantity of wastes generated at the hospitals.
Chromosome transfer experiments link regions on chromosome 7 to radiation resistance in human glioblastoma multiforme

Glioblastoma multiforme (GM) is the most lethal form of brain tumor, with a median survival of approximately 1 year. Treatment options are limited. Radiation therapy is a common form of treatment, but many tumors are resistant. In earlier studies, we found that gain of chromosome 7 is associated with radiation resistance in human primary GM. In this study, we extend that result to a model system in which we transferred chromosome 7 to recipient cells and confirmed radiation resistance as a function of chromosome 7 gain. We identified three candidate regions on chromosome 7 that conferred radiation resistance in our model system. © 2005 Wiley‐Liss, Inc.
Structural Changes of Inner and Outer Choroid in Central Serous Chorioretinopathy Determined by Optical Coherence Tomography

Purpose To determine the structural changes of the choroid in eyes with central serous chorioretinopathy (CSC) by enhanced depth imaging optical coherence tomography (EDI-OCT). Methods A retrospective comparative study was performed at two academic institutions. Forty eyes with CSC, their fellow eyes, and 40 eyes of age-matched controls were studied. Subfoveal cross sectional EDI-OCT images were recorded, and the hypo reflective and hyperreflective areas of the inner and outer choroid in the EDI-OCT images were separately measured. The images were analyzed by a binarization method to determine the sizes of the hyporeflective and hyperreflective areas. Results In the inner choroid, the hyperreflective area was significantly larger in the CSC eyes (35,640±10,229 μm2) than the fellow eyes (22,908±8,522 μm2) and the control eyes (20,630±8,128 μm2; P<0.01 vs control for both, Wilcoxon signed-rank test). In the outer choroid, the hyporeflective area was significantly larger in the CSC eyes (446,549±121,214 μm2) than the control eyes (235,680±97,352 μm2, P<0.01). The average ratio of the hyporeflective area to the total choroidal area was smaller in the CSC eyes (67.0%) than the fellow eyes (76.5%) and the control eyes (76.7%) in the inner choroid (P<0.01, both). However, the ratio was larger in the CSC eyes (75.2%) and fellow eyes (71.7%) than in the control eyes (64.7%) in the outer choroid (P<0.01, both). Conclusions The larger hyperreflective area in the inner choroid is related to the inflammation and edema of the stroma of the choroid in the acute stage of CSC. The larger hyporeflective areas in the outer choroid is due to a dilatation of the vascular lumens of the larger blood vessels. These are the essential characteristics of eyes with CSC regardless of the onset.
The System Design of a High-Speed Object Detector

We discuss the design of a high-speed object detection framework. More specifically we focus on rear view car detection. However the methods discussed are not limited to this object class. Our baseline detector uses integral channel features in a boosting framework reminiscent of Viola-Jones. With our baseline detector as starting point we consider the implementation and study of two approximation techniques that result in a significant detection speedup. The first approximation focuses on decreasing the time spent on classification of subwindows. The second approximation technique targets the multiscale aspect of our object detector. We show that these techniques result in a 17.5× speedup without sacrificing on detection rate. Based on these approximation techniques and a fast GPU implementation for extracting channel features we report detection speeds up to 55 fps without exploiting scene geometry or reducing the
Non-intrusive fault tolerance in soft processors through circuit duplication

The flexibility introduced by Commercial-Off-The-Shelf (COTS) SRAM based FPGAs in on-board system designs make them an attractive option for military and aerospace applications. However, the advances towards the nanometer technology come together with a higher vulnerability of integrated circuits to radiation perturbations. In mission critical applications it is important to improve the reliability of applications by using fault-tolerance techniques. In this work, a non-intrusive fault tolerance technique has been developed. The proposed technique targets soft processors (e.g. LEON3), and its detection mechanism uses a Bus Monitor to compare output data of a main soft-processor with its redundant module. In case of a mismatch, an error signal is activated, triggering the proposed fault tolerance strategy. This approach shows to be more efficient than the state-of-the-art Triple Modular Redundancy (TMR) and Software Implemented Hardware Fault Tolerance (SIHFT) approaches in order to detect and to correct faults on the fly with low area overhead and with no major performance penalties. The chosen case study is an under development On-Board Computer (OBC) system, conceived to be employed in future missions of the Brazilian Institute of Space Research (INPE).
Direct Detection of Legionella Species from Bronchoalveolar Lavage and Open Lung Biopsy Specimens: Comparison of LightCycler PCR, In Situ Hybridization, Direct Fluorescence Antigen Detection, and Culture

ABSTRACT We developed a rapid thermocycling, real-time detection (also known as real-time PCR) method for the detection of Legionellaspecies directly from clinical specimens. This method uses the LightCycler (Roche Molecular Biochemicals, Indianapolis, Ind.) and requires approximately 1 to 2 h to perform. Both aLegionella genus PCR assay and Legionella pneumophila species-specific PCR assay were designed. A total of 43 archived specimens from 35 patients were evaluated, including 19 bronchoalveolar lavage (BAL) specimens and 24 formalin-fixed, paraffin-embedded open lung biopsy specimens. Twenty-five of the specimens were culture-positive for Legionella (9 BAL specimens and 16 tissue specimens). BAL specimens were tested by LightCycler PCR (LC-PCR) methods and by a direct fluorescent antibody (DFA) assay, which detects L. pneumophila serogroups 1 to 6 and several other Legionella species. Tissue sections were tested by the two LC-PCR methods, by DFA, by an in situ hybridization (ISH) assay, specifically designed to detect L. pneumophila, and by Warthin-Starry (WS) staining. The results were compared to the “gold standard” method of bacterial culture. With BAL specimens the following assays yielded the indicated sensitivities and specificities, respectively: Legionella genus detection byLegionella genus LC-PCR, 100 and 100%;Legionella genus detection by DFA assay, 33 and 100%; andL. pneumophila detection by L. pneumophilaspecies-specific LC-PCR, 100 and 100%. With open lung biopsy specimens the following assays yielded the indicated sensitivities and specificities, respectively: Legionella genus detection by LC-PCR 68.8 and 100%; Legionella genus detection by DFA assay, 44 and 100%; Legionella genus detection by WS staining, 63 and 100%; L. pneumophila species-specific detection by LC-PCR, 17 and 100%; and L. pneumophilaspecies-specific detection by ISH, 100 and 100%. The analytical sensitivity of both LC-PCR assays was <10 CFU/reaction. LC-PCR is a reliable method for the direct detection of Legionellaspecies from BAL specimens. The Legionella genus LC-PCR assay could be performed initially; if positive, L. pneumophila species-specific LC-PCR could then be performed (if species differentiation is desired). The speed with which the LC-PCR procedure can be performed offers significant advantages over both culture-based methods and conventional PCR techniques. In contrast, for the methods evaluated, culture was the best for detecting multipleLegionella species in lung tissue. WS staining,Legionella genus LC-PCR, and L. pneumophilaspecies-specific ISH were useful as rapid tests with lung tissue.
Lithium therapy: from clinical trials to practical management

Controlled trials have shown that lithium significantly reduces the morbidity of recurrent affective disorders. We descibe here the ongoing affective morbidity in unipolar, bipolar and schizoaffective illness treated primarily by low dosage, once daily lithium, supplemented as necessary by antidepressant or neuroleptic medication. Seventy‐eight percent of unipolar patients and 73% of bipolar and schizoaffective patients had no or only slight morbidity during the study year. The treatment was equally effective for both older (age > 70 years) and younger patients. Unipolar patients rated as endogenous on the Newcastle Scale had significantly lower morbidity than the nonendogenous patients. Subjective side effects were minimal. These patients, whose untreated morbidity is known to be high, derive considerable benefit from regular supervision in an affective disorder clinic.
Privacy-Preserving Genome-Aware Remote Health Monitoring

Using genetic profiles of individuals for tailored diagnosis and treatment has great promise in the healthcare industry. Despite of the rapid growth in genome-aware medicine, genome-aware health monitoring has not been studied as well. A major stumbling block is the privacy issues of such applications. In addition to privacy concerns in a traditional health monitoring system, i.e., the privacy of users' biomedical sensing data and the protection of the proprietary health monitoring program, severe privacy concerns arise when users' genomic data are integrated into the health monitoring program due to the re-identification and phenotype attacks based on the DNA profile and the relevance of DNA information in a family. In this paper, we investigate these privacy risks and propose a privacy- preserving approach for genome-aware health monitoring. In our approach, users can only learn the diagnostic results based on their genomic and biomedical sensing data, while the the healthcare service provider learns nothing. Security analysis and performance evaluations are conducted to illustrate the effectiveness and efficiency of the proposed approach.
The School of Information 2013 Representation Patterns for Cultural Heritage Resources

The universe of available cultural heritage metadata schemas grows more complex every day. Existing schemas are optimized for use in the library, archive, or museum domains and to fit the needs of shared services and applications. Emerging Linked Data approaches introduce additional challenges for metadata designers and creators responsible for implementing these standards. In other domains, design patterns are used to clearly articulate problems, their contexts, and available solutions. This poster introduces preliminary research to identify such patterns in cultural heritage metadata standards using content analysis and a participatory design methodology.
