Controllability of affine systems on free Nilpotent Lie groups Gm,?
No full textControllability properties of affine control systems on free nilpotent Lie groups are examined and controllability of affine systems on thiskind of Lie groups are characterized by the help of their associated bilinear parts. In order to show this, an automorphism in the algebra level is found, authomosrpism orbit of the system is calculated and its properties are studied
A transmuted version of the generalized half-normal distribution
No full textAn extension of the generalized half-normal distribution, given by Cooray and Ananda [5], is proposed and studied. We use the quadratic rank transmutation map to generate a transmuted version of the generalized half-normal distribution. We study some probability properties, discuss maximum likelihood estimation and present real data application indicating that the new distribution can improve the generalized half-normal distribution in fitting real data
A certain subclass of uniformly convex functions defined by Bessel functions
No full textThe aim of the present paper is to investigate some characterization for generalized Bessel functions of the first kind is to be a subclass of analytic functions. Furthermore, we studied coefficient estimates, radius of starlikeness, convexity, close - to - convexity, convex linear combinations for the class T S(λ, γ). Finally we proved Integral means inequalities for the class
Autoagravamento não suicida e sua relação com o estilo de apego em uma amostra não clínica de adolescentes chilenos
No full textObjective: to establish the relationship between the presence of non-suicidal self-harm with the type of attachment in a sample of Chilean adolescents.
Method: A questionnaire was used to evaluate non-suicidals self-harm (American Psychiatric Association, 2014); and two questionnaires to measure attachment style (Gonzalez & Mendez, 2006; Morán, Lecannelier, & Rodríguez, 2014). A non-experimental, transversal and analytical study was carried out, was used Chi square for comparisons between the attachment style between those who self-harm and those who do not.
Results: 186 adolescents, with ages between 14 and 18 years old (M = 15.8, SD = 1.1), 57% correspond to women. 11% (22) of the subjects reported self-harm, 77.3% corresponded to women.
In subjects reporting with self-harm, 80.9% had an insecure type of attachment (4.8% avoidance attachment, 33.3% ambivalent attachment, and 42.8% disorganized attachment). 95.4% have medium to high scores on subscale signs of anger and anguish towards the figure of attachment.
Conclusions: Insecure and disorganized attachment styles are a factor of vulnerability that predisposes subjects to emotional deregulation.
Adolescents who report self-harm they tend to have less secure attachments, in contrast to those who do not self-harm (Hallab & Covic, 2010).Objetivo: establecer la relación entre la presencia de autolesión no suicida con el tipo de apego en una muestra de adolescentes chilenos.
Método: se utilizó un cuestionario para evaluar autolesiones no suicidas (American Psychiatric Association, 2014); y dos cuestionarios para medir estilo de apego ((Gonzalez & Mendez, 2006); Morán, Lecannelier, & Rodríguez, 2014). Se realizó un estudio no experimental, transversal y analítico, se utilizó Chi cuadrado para las comparaciones entre el estilo de apego entre los que se autolesionan y los que no Resultados: 186 adolescentes, con edades entre 14 y 18 años (M = 15.8, SD = 1.1), el 57% corresponde a mujeres. El 11% (22) de los sujetos reportaron autolesiones, el 77.3% correspondió a mujeres.
En sujetos que reportaron autolesiones, el 80.9% tenía un tipo de apego inseguro (4.8% de unión de evitación, 33.3% de unión ambivalente y 42.8% de unión desorganizada). El 95.4% tiene puntajes de medianos a altos en las subescalas de ira y angustia hacia la figura del apego.
Conclusiones: los estilos de apego inseguros y desorganizados son un factor de vulnerabilidad que predispone a los sujetos a la desregulación emocional.
Adolescentes que reportan autolesiones tienden a tener un apego menos seguro, en contraste con aquellos que no se autolesionan (Hallab & Covic, 2010). Objetivo: estabelecer a relação entre a presença de autolesões não suicidas com o tipo de apego em uma amostra de adolescentes chilenos.

Em indivíduos que relataram autoagressão, 80,9% apresentavam algum tipo de apego inseguro (4,8% de sindicato de evitação, 33,3% de união ambivalente e 42,8% de sindicato desorganizado). 95,4% apresentam médias a altas pontuações nas subescalas de raiva e angústia em relação à figura do apego.
Conclusões: Os estilos de apego inseguro e desorganizado são um fator de vulnerabilidade que predispõe os sujeitos à desregulação emocional.
Adolescentes que relatam auto-mutilação tendem a ter um apego menos seguro, em contraste com aqueles que não se auto-mutilam (Hallab & Covic, 2010)
A new type of generalized closed set via ?-open set in a fuzzy bitopological space
No full textThis paper aims to present the notion of (i, j)*-fuzzy γ-open set in a fuzzy bitopological space as a parallel form of (i, j)-fuzzy γ-open set due to Tripathy and Debnath (2013) [17] and show that both of them are independent concepts. Then we extend our study to (i, j)*-generalized fuzzy γ-closed set and (i, j)*-γ-generalized fuzzy closed set. We show that (i, j)*-γ-generalized fuzzy closed set and (i, j)*-generalized fuzzy γ-closed set are also independent of each other in nature. Though every (i, j)*-fuzzy γ-closed set is a (i, j)*-generalized fuzzy γ-closed set but with (i, j)*-γ-generalized fuzzy closed set, the same relation is not linear. Similarly though every (i, j)*-fuzzy closed set is (i, j)*-γ-generalized fuzzy closed set but it is independent to (i, j)*-generalized fuzzy γ-closed set. Various properties related to (i, j)*-generalized fuzzy γ-closed set are also studied. Finally, (i, j)*-generalized fuzzy γ-continuous function and (i, j)*-generalized fuzzy γ-irresolute functions are introduced and interrelationships among them are established. We characterized these functions in different directions for different applications.This paper aims to present the notion of (i,j)* fuzzy ?-open set in a fuzzy bitopological space as a parallel form of (i,j) fuzzy ?-open set due to Tripathy and Debnath (2013) [Tripathy, B.

(2013), ?-Open sets and ?-Continuous Mappings in Fuzzy Bitopological Spaces, Journal of Intelligence and Fuzzy Systems, 24, 631-635] and show that both of them are independent concepts. Then we extend our study to (i,j)* generalized fuzzy ?-closed set and (i,j)* ?-generalized fuzzy closed set. We show that (i,j)* ?-generalized fuzzy closed set and (i,j)* generalized fuzzy ?-closed set are also independent of each other in nature.

On nearly Lindelöf spaces via generalized topology
No full textIn this paper a new class of sets termed as ωμ-regular open sets has been introduced and some of its properties are studied. We have introduced μ-nearly Lindelöfness in μ-spaces. We have shown that under certain conditions a μ-Lindelöf space [7] is equivalent to a μ-nearly Lindelöf space. Some properties of such spaces and some characterizations of such spaces in terms of ωμ -regular open sets are given

Sentidos da rede de atenção psicossocial para pessoas em situação de rua
Get PDFObjective: To understand the perceptions of homeless people under alcohol and drug treatment of the Psychosocial Support Network (PSN) of a city in southern Brazil. Method: Information was gathered through semi-structured interviews applied to fifteen men, aged between 24 and 61 years old, who had been homeless from 2 months to 8 years. Interviews took place in the Psychosocial Care Center for the treatment of alcohol and other drugs that have CAPS ad III beds. Data was analyzed through the Perspective of Discursive Practices which hold two categories: experiences before accessing PSN and experiences after accessing PSN. Results: There is lack of information about existing services and concerns about accessing them. Bureaucracy within the network was also another factor affecting the perception, resulting in low intersectoriality. On the other hand, participants reported on fundamental reception experiences to re-signify the relationship with health teams and to open up the search for treatment. . Conclusion: There is a lack of information about existing services and distrust on the part of users to access themObjetivo: comprender el sentido de la Red de Atención Psicosocial (RAPS) para personas en situación de calle y en tratamiento de alcohol y drogas en una capital del sur de Brasil. Método: La información fue recolectada por medio de entrevistas semiestructuradas a 15 personas del sexo masculino, con edades entre 24 y 61 años, que estuvieron en situación de calle entre 2 meses y 8 años. Las entrevistas fueron realizadas en el Centro de Atención Psicosocial para tratamiento de alcohol y otras drogas que poseen camas (CAPS ad III). Para el análisis de los datos se utilizó la perspectiva de las Prácticas Discursivas de la cual transcurrieron las dos categorías: inicio del acceso a la RAPS y experiencias después de acceder a la RAPS. Resultados: La burocracia fue un factor que emergió en la articulación entre los dispositivos accedidos, resultando en abordajes de baja intersectorialidad. Por otro lado, los participantes narraron experiencias de acogida fundamentales para resignificar la relación con los equipos de salud y dar apertura para la búsqueda de tratamiento. Conclusión: existe falta de información sobre los servicios existentes y recelo por parte de los usuarios en acceder a ellosObjetivo: compreender os sentidos da Rede de Atenção Psicossocial (RAPS) para pessoas em situação de rua e em tratamento de álcool e drogas em uma capital do sul do Brasil.

Impacto de advertências sanitárias em cigarros em fumantes cubanos
No full textObjective: To evaluate the efficacy of mandatory cigarette sanitary warnings to persuade smokers. Method: The Tobacco Consumption Questionnaire (TCQ) was applied to a sample of 205 smokers from La Habana and Santiago de Cuba. Results: A 100 % of the sample classifies as high risk smokers according to the TCQ. Most of them do not read the cigarette sanitary warnings. These warnings have never prevented them from smoking. Conclusion: Mandatory cigarette sanitary warnings have no effect whatsoever on smokers. Some possible reasons might be historical and socio-cultural factors, insufficient contributions of Cuban laws, and other inconsistent public policies.Objetivo: Evaluar la eficacia de las advertencias sanitarias que de forma obligatoria se insertan en las cajetillas de cigarrillos para disuadir a los fumadores del consumo. Método: Se aplicó el Cuestionario de Clasificación de Consumidores de Cigarrillo (C4) y el registro de datos socio-demográficos correspondientes a una muestra conformada por 205 fumadores procedentes de las ciudades de La Habana y Santiago de Cuba. Resultados: Prácticamente la totalidad de los fumadores estudiados clasifica como fumadores de riego y fuerte según el C4 y la mayoría de ellos no lee las advertencias sanitarias y mucho menos les han hecho pensar en deja de fumar. Conclusión: Se evidencia la ineficacia de las advertencias sanitarias como recurso que convoca a los fumadores estudiados a la cesación del consumo y se analizan posibles causas vinculadas a factores históricos y socio culturales, a la insuficiente contribución de las normativas jurídicas cubanas para el control del tabaquismo y a otras inconsistencias en las políticas públicas.Objetivo: Avaliar a eficácia das advertências de saúde que são obrigatoriamente inseridas em maços de cigarros para impedir o consumo de fumantes. Método: Aplicou-se o Questionário de Classificação de Consumidores de Cigarro (C4) e o registro sociodemográfico correspondente a uma amostra composta por 205 fumantes das cidades de Havana e Santiago de Cuba. Resultados: Praticamente todos os fumantes estudados classificaram como fumantes pesados e pesados de acordo com C4 e a maioria deles não leu as advertências de saúde, muito menos os fizeram pensar em parar de fumar. Conclusão: A ineficácia das advertências de saúde é evidenciada como um recurso que convoca os fumantes estudados à cessação do consumo e analisa possíveis causas ligadas a fatores históricos e sócio-culturais, à insuficiente contribuição das normas legais cubanas para o controle do tabagismo. e outras inconsistências nas políticas públicas
