Using Fuzzy AHP to manage Intellectual Capital assets: An application to the ICT service industry

In today’s competitive business environment, Intellectual Capital (IC) management is ever more recognized as a fundamental factor in gaining competitive advantage. Actually, most firms have only a vague idea of how to manage investments in IC and what they should obtain from these investments. As a result, many companies overlook to balance IC investments, overinvesting in some IC components and neglecting other ones. Following this lead, the aim of the paper is to assess the relative importance of IC components, with respect to their contribution to the company value creation, in order to obtain guidelines for IC management and investments.We propose a model for IC evaluation by integrating Fuzzy Logic and Analytic Hierarchy Process (AHP). This Fuzzy AHP approach allows to capture and foster IC dynamics: experts and managers are greatly supported by the use of linguistic variables in the evaluation process of the company intangible assets. Finally, the application of the Fuzzy AHP methodology to a group of ICT service companies is presented.

I2-doped and pyrrole ring-iodinated semi-conducting oligomers of N-vinyl-3-alkyl-2-phenylpyrroles

I₂-doped and pyrrole ring-iodinated semi-conducting oligomers of N-vinyl-3-alkyl-2-phenylpyrroles have been synthesized by free-radical polymerization of the above monomers (AIBN, 2–5 wt%, 60–80 °C) and further exposure of the oligomers obtained to I₂ vapor. The parent oligomers exhibit paramagnetic and fluorescent properties and stable up to 300–370 °C.     

Sensitivity to ethanol-induced motor incoordination in 5-HT1B receptor null mutant mice is task-dependent: Implications for behavioral assessment of genetically altered mice.

Neuromuscular impairment by ethanol likely involves complex effects on balance, gait, muscle strength, and other features of motor coordination. The present experiments showed that relative sensitivity to ethanol-induced motor impairment in serotonin 1B (5-HT1B) null mutant and control mice was task dependent. We found that ethanol-treated null mutant mice made fewer missteps on a balance beam than did ethanol-treated wild-type mice, and confirmed a previous finding of their lesser ethanol sensitivity in the grid test. The genotypes did not differ in ethanol sensitivity as measured by the screen test, static dowel, fixed-speed rotarod, accelerating rotarod, grip strength, or loss of righting reflex tests. These experiments suggest that within a behavioral domain, alternative tests of function are not equivalent, so multiple assessment tools should be used to avoid misinterpretation of gene function.

Clients' sexually inappropriate behaviors directed toward clinicians: Conceptualization and management.

Sexually inappropriate behaviors in clinical settings are relatively common occurrences that may negatively affect the therapeutic process. For example, more than half of female psychologists have reported at least 1 incident in which a client responded in a sexually inappropriate manner. Thus, it is important for clinicians to understand inappropriate behaviors and respond in a manner that is both personally satisfying and helpful to the client. A framework for conceptualizing these behaviors is proposed, as well as components for, and examples of, therapeutic responses. Recommendations are provided for preventive measures to decrease the likelihood of inappropriate behaviors and for systemic approaches to benefit professional training in regards to these issues. Our aim is to stimulate further discussion of sexually inappropriate behaviors specifically by facilitating psychotherapists' ability to address clients' within-session sexual behavior, facilitating speculation of the antecedents of and motivations behind such behaviors, and facilitating discussion of such behaviors within supervision and, more broadly, within training programs.

Increasing attendance at colorectal cancer screening: Testing the efficacy of a mailed, psychoeducational intervention in a community sample of older adults.

This article describes a trial of a psychoeducational intervention designed to modify negative attitudes toward flexible sigmoidoscopy screening and thereby increase screening attendance. The intervention materials addressed the multiple barriers shown to be associated with participation in earlier studies. Adults ages 55-64 (N=2,966), in a "harder-to-reach" group were randomized either to receive an intervention brochure or to a standard invitation group. Attitudes and expectations were assessed by questionnaire, and attendance at the clinic was recorded. Compared with controls, the intervention group had less negative attitudes, anticipated a more positive experience, and had a 3.6% higher level of attendance. These results indicate that psychoeducational interventions can provide an effective means of modifying attitudes and increasing rates of screening attendance.

Misattribution of dissonance and behaviour-consistent attitude change.

Examined the prediction that people who have misattributed dissonance arousal to an external source may come to question the appropriateness of this attribution and may then be motivated to alter their attitudes. This was tested by having an experimenter discredit the plausibility of an external source after misattribution had presumably occurred. 80 female undergraduates participated in the study, with 16 of these Ss serving as controls. 64 Ss were given a pill described as having either unpleasant side effects or no side effects and then were committed to write counterattitudinal essays under high-choice conditions. Some Ss were then told that a mistake had been made and that they had actually been given the other form of the pill. As predicted, Ss who had initially been led to believe that the pill had aversive side effects but were later told that it did not manifested behavior-consistent attitude change.

Development and validation of a dissolution test for lodenafil carbonate based on in vivo data

Introduction: Lodenafil carbonate is a phosphodiesterase type 5 inhibitor used for the treatment of erectile dysfunction. Currently, there is no dissolution test reported for lodenafil carbonate and this drug is not listed in any pharmacopoeia.

Objective: The present study focused on the development and validation of a dissolution test for lodenafil carbonate tablets, using a simulated absorption profile based on in vivo data.

Methods: The appropriate conditions were determined after testing sink conditions. Different conditions as medium, surfactant concentration and rotation speed were evaluated. The percentage of dose absorbed was calculated by deconvolution, using the Wagner–Nelson method.

Results: According to the obtained results, the use of 0.1?M HCl?+?1.5% SLS (900?mL, at 37?+?0.5?°C) as the dissolution medium, paddles at 25?rpm were considered adequate. The samples were quantified by UV spectroscopy at 295?nm and the validation was performed according to international guidelines. The method showed specificity, linearity, accuracy and precision, within the acceptable range. Kinetics of drug release was better described by the first-order model.

Conclusion: The proposed dissolution test can be used for the routine quality control of lodenafil carbonate in tablets.     

Sperm surface changes and physiological consequences induced by sperm handling and storage

Spermatozoa interact with their immediate environment and this contact remodels the sperm surface in preparation for fertilisation. These fundamental membrane changes will be critically covered in this review with special emphasis on the very specific surface destabilisation event, capacitation. This process involves very subtle and intricate modifications of the sperm membrane including removal of suppression (decapacitation) factors and changes in the lateral organisation of the proteins and lipids of the sperm surface. Processing of sperm for assisted reproduction (storage, sex-sorting, etc.) subjects spermatozoa to numerous stressors, and it is possible that this processing overrides such delicate processes resulting in sperm instability and cell damage. To improve sperm quality, novel mechanisms must be used to stabilise the sperm surface during handling. In this review, different types of membrane stress are considered, as well as novel surface manipulation methods to improve sperm stability.     

Antimicrobial resistance of heterotrophic bacteria in sewage-contaminated rivers

Sewage-contaminated rivers are ecosystems deeply disturbed by human activity due to the release of heavy metals, organic pollutants and pharmaceuticals as well as faecal and pathogenic micro-organisms, which coexist with the autochthonous microbial population. In this study, we compared the percentage of resistance in faecal and heterotrophic bacteria in rivers with different degrees of sewage pollution. As a matter of fact, no correlation was found neither between the degree of sewage pollution and the percentage of antimicrobial resistant heterotrophic bacteria nor between the number of resistant faecal bacteria and that of resistant heterotrophic bacteria. Most of the resistant isolates from the Zenne river downstream Brussels were multi-resistant and the resistance patterns were similar among the strains of each phylogenetic group. The total microbial community in this polluted river (as evaluated through a 16S rRNA gene clone library analysis) appeared to be dominated by the phyla Proteobacteria and Bacteroidetes while the phylum TM7 was the third most represented.
