On the solution of the image recognition problem by a principal component method and linear discriminant analysis
Authors:   South Ural State University (National Research University), Mokeyev V. , Tomilov S. ,   South Ural State University (National Research University)
Published: September 2016

In the paper, some aspects of image analysis based on PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis) are considered. The main idea of this approach is that, firstly, we project the face image from the original vector space to a face subspace via PCA, secondly, we use LDA to obtain a linear classifier. In the paper, the efficiency of application of PCA and LDA to a problem of recognition of face images without their preliminary normalization is investigated. When the number of images in a class is not large, it is proposed that the training set is supplemented by images obtained by rotating, scaling and mirroring. In the images from the ORL and Feret databases, the influence of the training set expansion on the quality of recognition of unnormalized face images is studied. Also, a problem of increasing the efficiency of principal component calculation for large image samples is addressed. A linear condensation method is used as a new technique to calculate the principal components of a large matrix. The accuracy and performance of the developed algorithm are evaluated.

Published: September 2016

In this paper a problem of image matching is considered. We consider the matching of images, which represent the same scene recorded by different sensors. In this paper we discuss problems arising when there are uninformative areas on the images, in which points matching errors occur frequently. In the proposed technology a projective transform is constructed from reliable corresponding points in an informative area. And then this transform is used to determine and adjust the corresponding points in an uninformative area. Experimental results illustrate the effectiveness of the proposed technology.

A binary subwavelength four-zone transmission element with metasurface for simultaneously controlling the polarization and phase of laser light was synthesized and characterized. The element was manufactured in a silicon film spattered on a glass substrate. It performs the near-field conversion of a linearly polarized incident laser beam into a near azimuthally polarized beam with a phase shift of π at diametrically opposite points of the beam. In the far field, the converted beam produces an intensity maximum at the center, as opposed to the minimum from the azimuthally polarized beam.

In this paper we investigated the spatio-temporal instabilities of stationary lasing in broad-area class-B lasers. Conditions for the onset of filamentary instability and its spatio-temporal characteristics were obtained analytically. The lasing stabilization capabilities through varying laser parameters were considered. We have also shown that effective suppression of unstable field components may be achieved by external optical injection into the cavity.

This article describes mathematical tools that allow one to simulate the reflection at diffraction gratings generated on an arbitrary surface. To solve this problem an analog of the Kirchhoff method was used. As an example, we considered reflection at a grating generated on a spherical surface. For modelling such systems we developed a program that allowed us to carry out a numerical experiment. We discussed a possibility of generalization of the results onto arbitrary diffractive optical elements.

Published: September 2016

Nas ultimas duas décadas importantes mudanças políticas e econômicas ocorreram na América Latina. Assim, o objetivo deste trabalho é analisar a relação existente entre a evolução da democracia e desenvolvimento econômico para as principais economias dessa região. O marco teórico se origina em Lipset (1959) o qual afirma que dentre os fatores da sociedade que se ligam ao sistema político nenhum é tão amplamente aceito quando a relação existente entre democracia e nível de desenvolvimento econômico. A metodologia usada foi à técnica econometria de dados em painel com efeito fixo.Os resultados demonstram que a evolução do PIB per capita teve um papel determinante no processo de evolução dasdemocracias dos países estudados. Destarte os resultados do trabalho permitem concluir que o desenvolvimento econômico amplia a possibilidade de consolidação da democracia na América Latina.Palavras-chave: Democracia; desenvolvimento econômico; economias Latino AmericanasAbstract: In the last two decades, important political changes occurred in Latin America. Thus the objective of this study is toanalyze the relationship between the evolution of democracy and economic development for the major economies of thisregion. The theoretical framework is based on Lipset (1959) which states that, among the factors in society related to political system, none is so accepted as the relation between democracy and level of economic development. The methodology used was the econometric technique of panel data with fixed effects. The results show that the evolution of GDP per capita had a role in the process of evolution of democracies in the studied countries. Thus the results of the study allow concluding that economic development increases the possibility of consolidating democracy in Latin America.Keywords: Democracy, economic development, Latin American economies.
A CERTIDÃO NEGATIVA DE DÉBITO E A DECISÃO DE PAGAR TRIBUTOS
Authors: Paes Nelson Leitão
Published: September 2016

O artigo expõe que, para atender a previsão de exigência de regularidade fiscal do artigo 205 do Código Tributário Nacional, foi criada a Certidão Negativa de Débito (CND). Aponta que a CND é condição necessária para as firmas participarem do sistema de compras governamentais e representa um estímulo para as firmas manterem as suas obrigações tributárias razoavelmente em ordem. Para avaliação dos efeitos deste mecanismo sobre o cumprimento da obrigação tributária, constrói um modelo simples de equilíbrio parcial, verificando que, quanto mais tributado for o setor e/ou menor for a exposição do seu faturamento ao setor público, menores serão as exigências do governo para concessão da CND. Com base na solução do modelo e em dados das contas nacionais de 2006, identifica os setores em que o governo deveria ser mais exigente na emissão da certidão, como os serviços às empresas, construção, produtos farmacêuticos e serviços de informação. Constata, por fim, que os setores menos afetados pela CND são as empresas de eletrodomésticos, fumo, mineração e metalurgia.Palavras-chave: Evasão fiscal; CND; comportamento da firmaNEGATIVE DEBT CERTIFICATE AND THE DECISION TO PAY TAXESAbstract: The article exposes that, to attend the prevision of demand of tax regularity from the article 205 of the Nationaltributary Code was created the Negative Debt Certificate (CND in Portuguese).Points out that CND is a necessary condition to firms participate of the government shopping system and represents an incentive to firms maintain their tributary dutiesreasonably in order. In order to evaluate the effects of this mechanism about the fulfilment of tax obligation, it was constructed a simple partial equilibrium model, understanding that, the higher is the tax rate to the sector and/or the lower isthe exposure of its revenues to the public sector, the smaller the governments requirements for granting CND will be.Based on the solution of the model with the aid of Brazilian national accounts of 2006, identifies sectors where the government should be more rigid to give the CND, like services to firms, construction, pharmaceutical products and information services. Finally, it notes that, the sectors less affected by CND are appliances companies, cigarettes producers,mining and metallurgy.Keywords: Tax evasion, CND, firm behavior.

Las enfermedades virales en plantas causan pérdidas económicas importantes al reducir la calidad y rendimiento de los cultivos, lo que amenaza la seguridad alimentaria en algunos países.  Dada la escasez de recursos naturales, plantas con resistencia genética a virus han sido desarrolladas con éxito por ingeniería genética. Un buen entendimiento de los mecanismos básicos que controlan las interacciones entre virus y plantas, incluido el silenciamiento génico de virus por ácido ribonucleico (ARN) de interferencia, es necesario para diseñar mejores estrategias de manejo y métodos biotecnológicos que servirán para desarrollar e implementar resistencia antiviral en plantas. En esta revisión, presentamos modelos moleculares vigentes para explicar el silenciamiento génico de virus por ARN de interferencia y sus aplicaciones en biotecnología e ingeniería genética de plantas.

Background: Histamine seems to act, via H2 receptor, on inflammatory processes by stimulating interleukin (IL)‐6 and matrix metalloproteinase (MMP) release. As cimetidine is an H2 receptor antagonist, the authors hypothesize that this antiulcer drug reduces IL‐6, MMP‐1, and MMP‐9 immunoexpression in gingiva with induced periodontal disease (PD). To confirm a possible modulatory role of IL‐6 on MMPs, the relationship between IL‐6/MMP‐1 and IL‐6/MMP‐9 immunoexpression was evaluated.

Methods: Forty‐six male rats were distributed into the cimetidine group (CimG: received daily intraperitoneal injections of 100 mg/kg of body weight of cimetidine) or the saline group (SG). PD was induced by cotton ligature around the maxillary left first molars (PDSG and PDCimG). The right molars were used as controls (SG and CimG). After 7, 15, 30, and 50 days, maxillary fragments were processed for paraffin embedding or for transmission electron microscopy. Tartrate‐resistant acid phosphatase (TRAP)‐positive osteoclasts in the alveolar process surface and number of IL‐6, MMP‐1, and MMP‐9‐immunolabeled cells in the gingival mucosa were quantified. Statistical analyses were performed (P ≤0.05).

Results: In PDSG and PDCimG, gingival mucosa exhibited few collagen fibers among numerous inflammatory cells. In PDCimG, the number of TRAP‐positive osteoclasts and IL‐6, MMP‐1, and MMP‐9‐immunolabeled cells was significantly lower than in PDSG at all periods. A positive correlation between IL‐6/MMP‐1 and IL‐6/MMP‐9 was detected in PDSG and PDCimG.

Conclusion: Cimetidine decreases bone loss through reduction of osteoclast number and induces reduction of IL‐6, MMP‐1, and MMP‐9 immunoexpression, reinforcing the idea that the beneficial effect of cimetidine in PD may be due to reduction of IL‐6 immunolabeling in the inflamed gingival mucosa.

Background: Over the past decade, use of leukocyte platelet‐rich fibrin (L‐PRF) has gained tremendous momentum in regenerative dentistry as a low‐cost fibrin matrix used for tissue regeneration. This study characterizes how centrifugation speed (G‐force) along with centrifugation time influence growth factor release from fibrin clots, as well as the cellular activity of gingival fibroblasts exposed to each PRF matrix.

Methods: Standard L‐PRF served as a control (2,700 revolutions per minute [rpm]‐12 minutes). Two test groups using low‐speed (1,300 rpm‐14 minutes, termed advanced PRF [A‐PRF]) and low‐speed + time (1,300 rpm‐8 minutes; A‐PRF+) were investigated. Each PRF matrix was tested for growth factor release up to 10 days (eight donor samples) as well as biocompatibility and cellular activity.

Results: The low‐speed concept (A‐PRF, A‐PRF+) demonstrated a significant increase in growth factor release of platelet‐derived growth factor (PDGF), transforming growth factor (TGF)‐β1, epidermal growth factor, and insulin‐like growth factor, with A‐PRF+ being highest of all groups. Although all PRF formulations were extremely biocompatible due to their autogenous sources, both A‐PRF and A‐PRF+ demonstrated significantly higher levels of human fibroblast migration and proliferation compared with L‐PRF. Furthermore, gingival fibroblasts cultured with A‐PRF+ demonstrated significantly higher messenger RNA (mRNA) levels of PDGF, TGF‐β, and collagen1 at either 3 or 7 days.

Conclusions: The findings from the present study demonstrate modifications to centrifugation speed and time with the low‐speed concept favor an increase in growth factor release from PRF clots. This, in turn, may directly influence tissue regeneration by increasing fibroblast migration, proliferation, and collagen mRNA levels. Future animal and clinical studies are now necessary.

Health care personnel are often exposed to strenuous working conditions due to their nature of work. The study assessed whether job stress affects the organisational commitment of employees within the health institutions. A quantitative design was used; the sample consisted of 141 respondents from selected public health institutions within the Nkonkobe Municipality Region, Eastern Cape, South Africa. Cluster sampling was used to select the hospitals and then the simple random sampling was used to select the sample from the cluster. Pearson Correlation Analysis was used to solicit the sought relationships. Results of the study showed significant relationships between job stress and organisational commitment showing that job stress has an effect on the commitment of workers. These findings are helpful and useful to the health department in implementing policies and procedures that will reduce job stress in employees in order to ensure that high levels of commitment towards the organisation are maintained for optimal success.
Board Competencies, Network Ties And Risk Management Disclosure Practices In Non-Profit Organizations

Published: September 2016

In the current challenging economic environment, non-profit organizations (NPOs) are exposed to an array of risks and some of these risks are unique due to the characteristics of the organizations.  Understanding and managing these risks are crucial in ensuring sustainability of the NPOs and the responsibility lies with the board. However, risks management and disclosure of risks in NPOs is less well developed relative to for profit organizations and this may affect boards’ role in enhancing risk management practices of these organizations. As such, this study aims to examine the relationships between certain board characteristics: board competencies, network ties and risk management disclosure practices in NPOs. Information on these variables are obtained from content analysis of annual reports and Financial Information Forms of 219 NPOs registered with Companies Commission of Malaysia for the financial period 2011. Results of this study reveal that the overall extent of risk management disclosure practices is at a moderate level. In addition, only board competencies are significantly positively related to the extent of risk management disclosure practices while network ties are not. This infers that some board members acknowledge the importance of being engaged in risk management decision. However, lack of specific guide on risk management in NPOs may reduce the motivation of some board members to do so. The guidelines and relevant trainings to board members provided by relevant authorities may increase the understanding of key risks and management of these risks as part of good governance in NPOs.
Do Financial Analysts Facilitate Investors’ Assessment Of Earnings?: Evidence From The Korean Stock Market

Published: September 2016

This paper seeks to enhance our understanding of financial analysts in assisting market investors’ use of accounting earnings in the Korean stock market. We examine whether stock returns differentially reflect earnings information for firms with analyst coverage. We propose that the role of analysts as external monitors as well as information intermediaries enhances the market investors’ valuation of earnings. We find that market valuation of earnings is higher for firms with analyst following. Furthermore, market investors’ valuation of earnings increases (or decreases) with the number of analysts (or with the dispersion of analysts’ forecasts). This suggests that the beneficial effect of analysts arises through the quantity and quality of analysts’ information. This study contributes to the literature by investigating the important role of analysts in emerging market.
Propuesta metodológica para el análisis de las relaciones entre discurso e identidad
Authors: Fonseca Mendoza Clara Inés
Published: September 2016

Este artículo presenta un marco metodológico centrado en el análisis de las relaciones entre discurso e identidad, basado en la Teoría de la Valoración y en la consideración de los significados globales (tópicos) y locales, y el modo como ellos conducen a las estrategias de auto-presentación positiva y presentación negativa de los otros. La relación entre discurso e identidad se asocia con un estudio sobre formas de racismo cotidiano percibidas en Cartagena, Colombia. Debe recalcarseque se trata de presentar una propuesta metodológica; por esta razón, no se realiza un análisis del discurso en estricto sentido.Palabras clave: discurso, identidad, discriminación percibida. AbstractThis article presents a methodological framework for analysis of the relations between discourse and identity, based on the Appraisal Theory and on the consideration of global and local meanings and the way these lead to strategies of positive self-presentation and negative presentation of others. The relation between discourse and identity is associated to a study on forms of everyday racism perceived in Cartagena. This is a methodological proposal; for that reason, there is no discourse analysis in stricto sensu.Key words: Discourse, identity, perceived discrimination
