Fuzzy Recommendations in Marketing Campaigns

The population in Sweden is growing rapidly due to immigration. In this light, the issue of infrastructure upgrades to provide telecommunication services is of importance. New antennas can be installed at hot spots of user demand, which will require an investment, and/or the clientele expansion can be carried out in a planned manner to promote the exploitation of the infrastructure in the less loaded geographical zones. In this paper, we explore the second alternative. Informally speaking, the term Infrastructure-Stressing describes a user who stays in the zones of high demand, which are prone to produce service failures, if further loaded. We have studied the Infrastructure-Stressing population in the light of their correlation with geo-demographic segments. This is motivated by the fact that specific geo-demographic segments can be targeted via marketing campaigns. Fuzzy logic is applied to create an interface between big data, numeric methods for processing big data and a manager.Comment: conferenc

Nosocomial hepatitis C virus infection in a renal transplantation center

AbstractNosocomial hepatitis C virus (HCV) infections were recorded in the renal transplantation unit of the university hospital. There were cases of acute HCV infection with aggressive clinical courses diagnosed from a positive HCV RNA test in the early post-transplantation period and which remained anti-HCV negative. Their anti-HCV seronegativity was attributed to them having acquired HCV under intense immunosuppressive therapy and suggested that the aggressive clinical course could be due to the deficient immune response resulting in an inability to limit viral replication. There were also donors diagnosed as having acute HCV infection in the early post-operative period. Genotyping and sequence analysis for HCV were performed on the isolates of eight of these patients who were consecutively transplanted and of three donors whose recipients were infected with HCV prior to transplantation, and who acquired acute HCV infection after transplantation. Of the eight recipients in the first group three were genotype 1a, three were genotype 1b, one wasgenotype 3a, and the last one was genotype 4 according to Simmond's classification. Of the three donor-recipient couples both the HCV isolates from one couple were genotyped as 1b and the phylogenetic analysis indicated that the patients were infected with a common variant of HCV, but the genotypesof HCV isolates from the other couples were different. Recipients were genotype 1b and the donors were genotype 1a in these couples. Genotype results of the first group and donor-recipient couples, and sequence analysis of genotype 1b and 1a isolates, showed that the source of infection was not a unique strain and there were multiple breaks in universal precautions while managing these patients

Manipulating the alpha level cannot cure significance testing

We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple independent studies. When evaluating the strength of the evidence, we should consider, for example, auxiliary assumptions, the strength of the experimental design, and implications for applications. To boil all this down to a binary decision based on a p-value threshold of 0.05, 0.01, 0.005, or anything else, is not acceptable

Towards Comprehensive Foundations of Computational Intelligence

Abstract. Although computational intelligence (CI) covers a vast variety of different methods it still lacks an integrative theory. Several proposals for CI foundations are discussed: computing and cognition as compression, meta-learning as search in the space of data models, (dis)similarity based methods providing a framework for such meta-learning, and a more general approach based on chains of transformations. Many useful transformations that extract information from features are discussed. Heterogeneous adaptive systems are presented as particular example of transformation-based systems, and the goal of learning is redefined to facilitate creation of simpler data models. The need to understand data structures leads to techniques for logical and prototype-based rule extraction, and to generation of multiple alternative models, while the need to increase predictive power of adaptive models leads to committees of competent models. Learning from partial observations is a natural extension towards reasoning based on perceptions, and an approach to intuitive solving of such problems is presented. Throughout the paper neurocognitive inspirations are frequently used and are especially important in modeling of the higher cognitive functions. Promising directions such as liquid and laminar computing are identified and many open problems presented.

Experimental And Theoretical Investigation Of Electrophylic Iodination Reaction Of 1-(N-O-Methyl- Phenyl Iminomethyl)-2-Naphthol In Dmso/H2so4 Environment

Bu çalışmada, o-metilanilin ve 2-hidroksi-1-naftaldehit reaksiyonundan elde edilen 1-(N-o-metil-fenil iminometil)-2-naftol, iyot ile DMSO/H2SO4 ortamında reaksiyona sokulmuştur. Elde edilen üç ürünün yapıları IR ve UV spektroskopik analiz metotlarıyla belirlenmiştir. Gerçekleştirilen elektrofilik aromatik iyot sübstitusyon reaksiyonunun mekanizması, Gaussian03W programıyla, kuantum kimyasal hesaplama metotlarından DFT metodu kullanılarak, B3LYP parametresi ve 3-21G temel seti seçilerek hesaplanmıştır. Olası ürünler ile reaksiyon ara ürünleri araştırılmış ve ara ürünler frekans hesaplaması yapılarak doğrulanmıştır. Deneysel ve teorik sonuçlar karşılaştırıldığında en kararlı ürünün -CH=N- (imin) grubuna göre para- konumundan iyotlanma ile oluşacağı anlaşılmıştır. para- konumunun iyotlanarak bloke edildiği durumda ise ikinci iyotlamanın, naftolik Schiff bazının orto- konumunu tercih ettiği sonucuna varılmıştır.In this study, 1-(N-o-methyl-phenyliminomethyl)-2-naphthol which obtained from o-methylaniline and 2-hydroxy-1-naphtaldehyde reaction, was reacted with iodine in DMSO/H2SO4. The structures of obtained three products were determined by IR and UV spectroscopic analysis. The reaction mechanism of performed electrophilic aromatic iodine substitution was calculated by using Gaussian03W on DFT quantum chemical calculation method, while B3LYP parameters and 3-21G basis set was selected. The possible products and reaction intermediates were investigated and intermediates were verified by frequency calculation. When experimental and theoretical results was compared, it was understood that the most stable product occurred to the para-position of the phenyl ring with respect to the -CH=N- (imin) group. When the para-position was blocked with a iodine substituent, the second iodination preferred in the ortho-position to phenyl ring of naphtholic Schiff base

Personality attributes as predictors of psychological well-being for NCOs

The authors examined the nature of the relationships between job-specific personality dimensions and psychological well-being for noncommissioned officers (NCOs) in the Turkish Armed Forces (TAF). A job-specific personality inventory, comprising measures of 11 personality dimensions was developed for selection purposes. The inventory was administered to a representative sample of 1,428 NCOs along with a general mental health inventory developed by the authors, which consisted of 6 dimensions of psychological well-being. Exploratory and confirmatory factor analyses suggested existence of a single factor underlying the 6 psychological well-being dimensions, Mental Health, and 2 latent factors underlying the 11 personality dimensions, Military Demeanor and Military Efficacy. The 2 personality constructs explained 91% of the variance in the Mental Health construct. A stepwise regression indicated that beta weights of the personality measures were significant except for military bearing, orderliness, and dependability. Results suggest that job-specific personality attributes were predictive of mental health. Implications of the findings for the selection of NCOs are discussed
