Los sistemas de información y las TIC al servicio de la gestión del conocimiento y el capital intelectual

The knowledge assets owned by an organization are supposed an important part of its value and sometimes they are not known neither for the firm nor for external agents interested in its activity. It leads traditional methods for spreading information don't offer a faithful firm's image, requiring alternative instruments that complement them. Hence, knowledge maps, intellectual capital report and the balanced scorecard are proposed. Both first can be used like non financial information tools, providing information towards into the organization and outside of it repectively, vhereas the balanced scorecard is a composed perspective for financial and non financial information, and would be direct to firms and stakeholders. Additionally, it's commented the information and communication technologies' rol in knowledge management processes.
Analysis of Influencing Factor on Household Financial Assets: The Case of Beijing

This paper regards Beijing households as object of study. Based on household disposable income, wealth, consumption, risk and profession character, this paper presents a detailed analysis of influencing factor about household financial assets by using aggregate and survey data. We find that at present household income, consumption, portfolio have not formed a good cycle. Therefore our government needs strengthen and improve macroeconomic management such that households can reasonably arrange their financial assets.
5-Year Trends in QSAR and its Machine Learning Methods.

BACKGROUND Quantitative Structure-Activity Relationships (QSAR) is a well-established branch of computational chemistry. The presence of QSAR papers is decreasing for the last few years. OBJECTIVE To highlight recent trends of QSAR in general and trends of machine learning methods in particular. METHOD A bibliometric analysis of articles published in top ten molecular modeling and medicinal chemistry journals was carried out. The bibliometric statistics was collected for papers published in 2009 and 2015 and compared. RESULTS During 5-year span studied, the fraction of QSAR studies underwent a twofold decrease. Top journals of both categories became less likely to publish Multiple Linear Regression models and increased the presence of Random forest and Naïve Bayes methods. 3D-QSAR remains the most popular method of studying structure-activity relationships with a slight decrease of its presence in molecular modeling journals but a relative increase in medicinal chemistry. CONCLUSION The downward QSAR trend might have several reasons: more stringent criteria for QSAR studies acceptance by journals, transformation of QSAR studies into routine work due to wider availability of QSAR methods and the overall maturation of QSAR field, and possible disappointment in QSAR. We expect that the progress in machine learning methods being adopted by chem(o)informaticians finally will help QSAR to find its place in drug design and to move to the Plateau of Productivity.
Improving retrieval rates for retrievable inferior vena cava filters

The introduction of retrievable inferior vena cava (IVC) filters was an important step in the evolution of deep vein thrombosis/pulmonary embolism management. Their removability makes them preferred to permanent filters in many cases. IVC filter retrieval often occurs at a suboptimal rate, leading to complications associated with long-term placement. Improving retrievability includes solutions for patients being lost to follow-up, filter malpositioning, need arising for permanent IVC filtration, filtration requiring longer than the filter’s window of retrievability, and filter compromise by the presence of a large trapped clot. This review explores these strategies for retrieval in detail in hopes of improving IVC filter retrieval rates.

Managing employee empowerment in luxury hotels in Europe

Purpose – This paper aims to test four potential predictors of the behavior of empowered employees during the delivery of service to customers.Design/methodology/approach – A questionnaire measuring employees' perceptions of training, performance‐related rewards, customer‐oriented culture, empowering management style, and empowered behavior was filled out by 356 frontline employees of 16 luxury hotels in seven European countries. These statistical analyses removed common‐method bias.Findings – Results of regression analyses at the department level showed that two means of control – customer‐oriented culture and empowering management style – correlated significantly with empowered behavior.Research limitations/implications – The survey tool would benefit from further refinement. Creative replications of the survey in different service or hotel settings may benefit service managers, consultants as well as consumers, ultimately.Practical implications – A direct implication of this study's findings is that in.
Model for visual luminance discrimination and flicker detection.

A model for vision is proposed. Its basic units are RC stages whose time constants—in three instances—are parametrically controlled. The requirements of compressing the dynamic range of the input and of fitting luminance pulse-detection data suffice to determine the arrangement and parameters of the components. This model accurately predicts the psychophysical results of flicker detection (DeLange characteristics at above 10 Hz), the Ferry–Porter and Weber laws in the ranges where they apply, the effects of light adaptation, and it accounts for individual differences. By considering the variable RC stage as an approximate analog of a synaptic excitatory process which is controlled by inhibition, significant correspondences are observed between the internal connectivity of the model and the neural connectivity of the retina.
An ultrastructural comparison of the mononuclear leucocytes and thrombocytes in six species of domestic bird.

The mononuclear cells of normal avian peripheral blood are medium and small lymphocytes, monocytes and thrombocytes. Strictly speaking, the nucleated erythrocytes should also be included in this group but they have not been considered in this study. Apart from work by Simpson (1968) on the thrombocytes and lymphocytes of the turkey the only other detailed ultrastructural descriptions of avian mononuclear leucocytes are those of the fowl (Enbergs & Kriesten, 1969; Maxwell & Trejo, 1970). Lucas & Jamroz (1961) classified lymphocytes into large, medium and small, adding that, in normal blood, only the medium and small types were found. The ultrastructure of the fowl's lymphocyte was described by Kriesten & Enbergs (1970) but they did not differentiate between medium and small types. In the present study the ultrastructural features of lymphocytes, monocytes and thrombocytes are described in six species of domestic bird, and stress is laid on the characteristics distinguishing medium from small lymphocytes. Occasionally plasma cells were encountered in the peripheral blood of all six species, but their description is not included here.
Relationship between BMI, PSA and Histopathological Tumor Grade in a Caucasian Population Affected by Prostate Cancer

The aim of this work is to show the relationship between obesity and aggressivenes of Prostate Cancer. We conducted a retrospective study of 132 men affected by Prostate Cancer underwent radical prostatectomy. Gleason score was abstracted by biopsy specimens and by post-operatory specimens. We evaluated PSA level and Body Mass Index (BMI). The prevalence of Post Operative Gleason Score > 8 among subjects with lowest tertile of PSA was higher in obese (BMI > 30 Kg/m2) (94.4%) vs overweight subjects (BMI 25-29.9 Kg/m2) (19.2%) (p 8 among subjects with second tertile of PSA was higher in obese (100%) and overweight (70%) vs normal weight subjects (0%) (p 8 among subjects with third tertile of PSA was higher in obese (100%) and overweight (62%) vs normal weight subjects (0%) (p<0.05 respectively). We believe that changes in the levels of PSA and Gleason Score, observed as a function of class BMI, could be due to separate mechanisms: PSA levels could be influenced by the effect of dilution by increased plasma volume of the subjects obese, while tumor grade could be affected by the hormonal changes induced by adipose tissue.
Organic food consumer profile in the Republic of Serbia

Purpose – Having the discrepancies between different descriptions of an organic food consumer profile in various researches worldwide as well as the causes of their emergence as a starting point, the purpose of this paper is to apply the method of preference-based market segmentation (by means of conjoint and cluster analysis) to Serbian organic food market, searching for advantages of using that methodological approach and deepening knowledge about specific organic food market. Design/methodology/approach – The research was conducted from May to July 2014 with 400 respondents participating (aged 18-30). Primary data were gathered by means of focus groups and a survey – structured personal interviews by using a questionnaire. Findings – When applying conjoint and cluster analysis to data about Serbian consumers’ preferences towards researched product, it is possible to identify a segment that prefers organic food the most. Compared to other segments, these consumers are predominantly female, somewhat more.
Pathophysiology to Phenotype in the Asthma of Obesity

Abstract Obesity affects numerous diseases, including asthma, for reasons that remain incompletely understood. Recent research suggests that the asthma of obesity is not a single disease, and that it breaks out into at least two distinct phenotypes. One phenotype is conventional allergic asthma modulated by obesity, whereas another arises solely due to the presence of obesity. The latter is postulated to be a consequence of the chronic lung compression caused by the obese chest wall in individuals with particularly collapsible lungs. Allergic obese asthma, on the other hand, appears to result from the way that obesity affects the immune system, which we hypothesize can be understood in terms of effects on the dynamic regulation of the inflammatory response.
A clinical study of edentulous patients rehabilitated according to the "all on four" immediate function protocol.

PURPOSE The aim of this study was to compare definitive acrylic resin prostheses with or without a cast metal framework that were immediately loaded and supported by axial and tilted implants in completely edentulous patients after 3 years of function. MATERIALS AND METHODS Patients who were completely or partially edentulous in one or both arches with severe atrophy of the posterior regions were selected for this study. All patients immediately received prosthetic rehabilitations, each supported by four implants (two axial and two tilted). The patients were randomized to receive a definitive prosthesis with a cast metal framework or one made of acrylic resin only. Follow-up visits were performed up to 36 months after implant insertion and included radiographic assessments of bone levels around the implants. RESULTS Thirty-six patients participated, and 44 complete-arch immediately loaded prostheses (24 maxillary and 20 mandibular), each supported by four implants (in total 176 implants), were placed. In all, 21 screw-retained full-arch acrylic resin prostheses and 23 cast-metal-framework prostheses were delivered to the patients. The 3-year overall implant survival rate was 100% for axially positioned implants and 96.59% for tilted implants. Implant survival rates were 98.96% in the maxilla and 97.5% in the mandible. None of the 44 fixed prostheses were lost during the observation period, representing a prosthetic survival rate of 100%. No statistically significant differences were seen in crestal bone loss between tilted and axial implants at 12, 24, and 36 months in either arch. CONCLUSIONS The same clinical outcome was seen for patients treated with the so-called All on Four protocol, regardless of whether the acrylic resin restorations were reinforced with metal.
Development of an analog simulator for the transient analysis of electric circuits, with the aim of teaching circuit phenomena by simulating equations

Teaching electric circuit theory involves the use of Ohm's and Kirchhoff's laws; branch, mesh and node analysis, as well as AC analysis and transient analysis. The latter gives the most comprehensive insight into circuit behavior. When analytical transient circuit analysis is used, one needs to solve the differential equations that describe the circuit behavior. Electrical engineering students often find this difficult. Alternatives to the mathematical analysis are: a) the simulation of the given problem with a commercial circuit simulator, and b) building a physical circuit, the behavior of which can then be observed and analyzed. These approaches are most productive when optimizing the behavior of a circuit, but they can easily add their own noise to the circuit study. The presented approach for the effective transient analysis is by simulating equations. The circuit in question is analyzed using Kirchhoff's laws with reference to specific time slices. The equations describing circuit components that store energy (capacitors, inductors) are then used to connect the consecutive time slices. The coding of equations for a given circuit allows students to gain a thorough understanding of the circuit's workings. Test cases show that results match perfectly between the simulation of equations and the analytical results from different RLC example circuits. Keywords: electronics education, electrical circuit simulation, simulation of equations, time variant circuit, transient response
Functional roles of histidine and tyrosine residues in the H(+)-peptide transporter PepT1.

Histidyl residues in peptide transporters PepT1 and PepT2 are believed to participate in proton and substrate binding and to be crucial to the transporters' functional activities. In the present study, we performed mutagenesis of rabbit PepT1. We mutated three histidine residues (H57, H111, and H121) predicted to reside in transmembrane segments, as well as tyrosine residues adjacent to H57. Functional analysis of wild-type and mutant PepT1 expressed in Xenopus oocytes, using both the radiotracer methods and two-microelectrode voltage-clamping, revealed that not only the H57 but also the aromatic residues near H57 were essential for the normal function of PepT1, in agreement with the concept that aromatic residues stabilize the charge on H(+) when interacting with H57. While mutagenesis at H111 did not significantly affect the activity of PepT1, mutagenesis at H121 had profound implications. The substrate affinities for H121 mutants were decreased depending both on the charge of the substrate and the charge on the substituted residues at position 121. We propose that H57 and H121 are intimately involved in the binding of the coupling ion H(+) and the recognition of transportable peptide substrates, respectively.
Late Gadolinium Enhancement in Cardiac Sarcoidosis: Characteristic Magnetic Resonance Findings and Relationship With Left Ventricular Function

Purpose: Cardiac involvement is an important prognostic factor in sarcoidosis, and cardiovascular magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE) can facilitate the identification of cardiac sarcoidosis (CS). In patients with CS, we investigated LGE characteristics and their relationship with left ventricular (LV) function to identify those characteristics unique to severely reduced LV function. We also investigated the relationship between LGE and duration of sarcoidosis. Materials and Methods: We retrospectively evaluated 19 patients with CS diagnosed according to the 2006 revised guidelines of the Japanese Ministry of Health and Welfare who underwent CMR imaging. We analyzed LGE location using 17-segment and subsegment (subepicardial, midwall, subendocardial, and transmural) models and evaluated the relationship between the characteristics of LGE and LV ejection fraction (LVEF) and duration of sarcoidosis. Results: Images of 17 of the 19 patients showed LGE most frequently in the subepicardial layer. The total number of affected segments with LGE correlated significantly with LVEF (r=−0.84, P<0.0001) and LV-diastolic volumes (r=0.88, P<0.0001). Transmural lesions were significantly more common in patients with LVEF of 35% or lower than in those with LVEF exceeding 35% (P=0.0004). All patients with LVEF of 35% or lower had both subepicardial and transmural lesions. The total number of affected segments with LGE correlated with the duration of sarcoidosis in patients with onset in an extracardiac organ (r=0.76, P=0.005). Conclusions: Demonstration of a characteristic LGE pattern and location allows diagnosis of CS, and CMR imaging with LGE aids in prediction of LV function.
Nocardia asteroides. A taxonomic study with clinical correlations.

The species, Nocardia asteroides, is generally considered to be heterogeneous, and several systems of dividing it into subgroups or separate species have been proposed. Sixty-five cultures of N. asteroides were analyzed by a battery of morphologic, physiologic, and biochemical tests. By means of 6 of these tests—acetamidase and benzamidase activity, growth at 45° C, assimilation of ethanolamine, and production of acid from rhamnose and fructose—these isolates could be divided into 2 well defined subgroups. Five African isolates of N. farcinica were found to be distinct from each of the 2 subgroups. Clinical information obtained for 45 of the 65 isolates of N. asteroides indicated that the frequency of proved pathogens and the type of clinical disease produced was the same in both subgroups.
Zinc protoporphyrin (ZPP): a simple, sensitive fluorometric screening test for lead poisoning.

The predominant fluorescent porphyrin that appears in erythrocytes as a result of chronic lead absorption or iron deficiency anemia is zinc protoporphyrin. This compound can be fluorometrically assayed in diluted whole blood with high sensitivity. An extremely simple and rapid test for lead absorption is described that is based on this assay. Results of a field trial indicate that this test should be seriously considered as a primary screening test for monitoring the effects of chronic lead absorption.
NORMATIVE BARRIERS TO IMITATION: SOCIAL COMPLEXITY OF CORE COMPETENCES IN A MUTUAL FUND INDUSTRY.

Limits on the imitability of innovations are central to discussions on sustainable competitive advantage. While prior work has focused on limitations on the ability to imitate we argue that it is only the third step in the imitation procedure. Limitations on imitability deriving from the two first steps, recognition of what to imitate and the willingness to imitate, have received almost no research attention. In this paper we focus on limitations on imitation that derive from unwillingness to act. Drawing on the resource based view and institutional theory we test hypotheses of what limits firms willingness to imitate particular new products and we develop the notion of strategizing on norms. We furthermore discuss the complex relationship between institutionalized norms, core competences and systematic differences in the willingness to imitate new products.
Signaling mechanism of corporate payout policy: A case of Indian firms

Article history: Received July 5, 2015 Received in revised format August 16 2015 Accepted January 6 2016 Available online January 11 2016 Historically, cash dividends are the most important form of payout policy; however, they have been losing popularity relative to share repurchases. This paper examines the signaling effect of the payout decisions namely, cash dividends and share repurchases by BSE 500 index companies. It attempts to uncover the underlying forces behind the firm’s choices of payout policy in the Indian context. Using the standard ‘Event Standard Methodology’, a strong case of positive signaling is reported in case of repurchase announcements vis-a-vis cash dividend announcements. It is observed that cash dividends are not perceived by investors as positive signals as they prefer their earnings to be retained by the companies for growth prospects. In case of share repurchases, the existence of undervaluation, signaling and wealth transfer hypotheses is reported, consistent with the fact the share repurchases are welcomed by the Indian companies. The results would provide insights into the economics of the choice between cash dividends versus share repurchases as payout mechanism adopted by the sample companies. The findings would also be useful to the academia as well as industry in understanding the payout practice and the extent to which the Indian managers use the assumptions, models and decision rules regarding payout.

Personal selling approaches used in television shopping

Television shopping simulates a personalized selling situation: it combines salesmanship with parasocial interaction. Segments of two major shopping channels, Home Shopping Network (HSN) and Quality Value Convenience (QVC), were coded for the use of persuasion strategies by the host, co‐host, or callers. The specific persuasion strategies coded were those identified by Cialdini, strategies that often cause a person to automatically say yes in a selling situation when they might otherwise say no. Although all strategies were evident, the strategy used most frequently in the 104 segments was social proof (35.5 percent), followed by scarcity (28.4 per cent) and authority (18.4 percent).
O Efeito da Diversificação Corporativa na Estrutura de Capital das Firmas Brasileiras 1 The Effect of Corporative Diversification on the Capital Structure of Brazilian Firms

This study aims to determine whether corporate diversification increases the borrowing capacity of Brazilian companies by means of cross- pledging. Using a panel data model, we estimated the relationship between leverage and the degree of corporate diversification using a sample of companies listed on the Sao Paulo Stock Exchange (Bovespa) between 2009 and 2011 and Brazilian companies with access to international markets through American Depositary Receipts (ADRs) in the period 2003-2011. Using empirical tests, we found no relationship between diversification and debt in either sample, indicating that a strategy of corporate diversification should not be used as a strategy to expand a company's financing capacity.
