Análise das contingências presentes em situação de orientação de pais na clínica analítico-comportamental infantil

A terapia analítico-comportamental infantil, embasada pelos pressupostos do Behaviorismo Radical e pelos princípios da Análise do Comportamento, é caracterizada por atendimento da criança em consultório e orientação de pais. Estudos têm apontado dificuldades encontradas pelos psicólogos em relação aos resultados clínicos no que se refere à generalização de ganhos terapêuticos. Apesar das investigações concluírem que os programas de intervenção com pais têm apresentado resultados satisfatórios, a prática clínica relata problemas em relação à generalização, principalmente quando avaliados ao longo do tempo. A presente pesquisa teve como objetivo compreender o processo de orientação de pais a partir de relações de elementos descritos pela literatura como influentes no processo de generalização de ganhos terapêuticos. Foi aplicado questionário, construído pela autora e sua orientadora a partir da bibliografia de referência da área estudada, com análise de especialistas e análise cognitiva dos itens (aplicação a 5 indivíduos com características semelhantes às dos nossos participantes), em 38 pais de crianças atendidas por psicólogos analistas do comportamento na cidade de Fortaleza-Ce, Brasil. Os dados foram avaliados a partir de uma análise descritiva (Tendência Central e Dispersão). Os itens do questionário foram classificados em nove categorias que foram compreendidas a partir da análise de correlação de Spearman por meio do programa estatístico SPSS. Os resultados constataram correlações positivas e significativas entre o processo de generalização e as categorias estudadas (Relação terapêutica; Ocorrência da orientação de pais; Ocorrência da generalização - Percepção dos pais; Treino de habilidades sociais para pais; Dinâmica familiar - Dificuldades no contexto familiar; Dinâmica familiar - Participação do cônjuge nos processos de orientação/generalização; Estabelecimento de regras funcionais pelos pais; Dificuldades pessoais dos pais), indicando que o psicólogo precisa avaliar e intervir nestas variáveis com o objetivo de contribuir para melhores efeitos no processo terapêutico.

Perceção da autoeficácia do terapeuta e aliança terapêutica na perspetiva do cliente

Estudos recentes apontam para a necessidade de explorar o processo psicoterapêutico, na perspetiva do cliente e do terapeuta. Apesar da importância reconhecida do estudo dos mecanismos de transformação terapêutica, existe uma lacuna na investigação no que respeita à associação entre a autoeficácia dos terapeutas e a aliança terapêutica. Com efeito, o objetivo principal do presente estudo foi analisar de que forma a perceção de autoeficácia do terapeuta se relaciona com o modo como o cliente perceciona a aliança terapêutica. Participaram neste estudo 128 participantes, distribuídos por 32 terapeutas e 96 clientes, numa proporção de três clientes para cada terapeuta. A autoeficácia dos terapeutas foi avaliada através do Counselor Activity Self-Efficacy Scales (CASES-G) e a aliança terapêutica percecionada pelos clientes através do Inventário de Aliança Terapêutica (IAT; versão C reduzida). O resultados revelaram que os terapeutas percecionaram-se como eficazes em relação ao processo psicoterapêutico e que os clientes reportaram uma forte aliança terapêutica. As análises de correlação indicaram que a subescala “gestão de sessão” do CASES-G se associou negativamente à subescala “tarefas” do IAT. Estes dados sugerem que um terapeuta mais confiante na sua capacidade para desempenhar competências técnicas específicas no que respeita à gestão da sessão, poderá ter mais dificuldade em investir no cliente e no processo psicoterapêutico, o que se poderá traduzir numa menor sincronia entre ambos e num indicador de perda da qualidade da aliança terapêutica.

Conocimientos, actitudes y prácticas en la salud sexual y la salud reproductiva: propuesta de una escala psicométrica

En este artículo se presenta el resultado del análisis de validez y confiabilidad de las escalas propuestas para medir conocimientos, actitudes y prácticas en salud sexual y salud reproductiva de la población estudiantil de la Universidad Nacional. La escala inicial estuvo conformada por 288 ítemes divididos en cuatro dimensiones (salud sexual, salud reproductiva, VIH/ SIDA e infecciones de transmisión sexual y uso del condón) y cada dimensión en tres categorías (conocimientos, actitudes y prácticas). El tratamiento de la escala inició con un análisis de validez aparente a partir de la evaluación de 12 personas expertas en la temática, luego se procedió con un análisis de factores, uno de correlación y se terminó con un análisis de confiabilidad que arrojó un Alfa de Cronbach de 0.9290, para concluir que la escala tiene una excelente consistencia interna. Finalmente, se construyó una nueva escala con 128 ítemes agrupados en las tres categorías y las cuatro dimensiones propuestas. Abstract In this document, the results of the validity and reliability analysis of the scales propose to measure knowledge, attitudes and practices in sexual health and reproductive health of the students of the Universidad Nacional, are presented. The scale was primarily composed of 288 items divided in four dimensions (sexual health, reproductive health, HIV/AIDS and sexual transmitted diseases, and condom use), and each dimension in three categories (knowledge, attitudes and practices). The treatment of the scale began with a face validity analysis from the evaluation of 12 experts and then with a factor analysis, correlation analysis and finished with a reliability analysis that gave a result a Cronbach coefficient of 0.9290, leading to the conclusion that the scale has an excellent internal consistency. Finally, a new scale was constructed with 128 items, gathered in the three categories and four dimensions proposed.

Levels of salivary immunoglobulin A under psychological stress and its relationship with rumination and five personality traits in medical students

Background and Objectives: The measurement of salivary immunoglobulin A is a useful and non-invasive method for measuring stress. Personality traits and rumination act as possible mediators in the relationship between psychological stressors and the immune system. This study was aimed to evaluate the levels of salivary IgA under psychological stress and its relationship with rumination and five personality traits in medical students. Methods: In this cross- sectional study, 45 medical students who intended to participate in the final exam were selected by simple random sampling. Two months before the exam, in the basal conditions, the NEO Personality Inventory-Short Form and Emotional Control Questionnaire (ECQ) were completed. Saliva samples were taken from students in both the basal conditions and exam stress conditions. Salivary IgA was measured by an ELISA test. Data was analyzed using paired samples T-test, Pearson correlation analysis, and stepwise regression. Results: A significant reduction of salivary IgA levels was found in exam stress conditions. Also, a significant negative correlation was found between traits of neuroticism and rumination with salivary IgA, as well as a significant positive correlation between of openness to experience and emotional inhibition with salivary IgA. Openness to experience and emotional inhibition may predict a substantial variance (34%) of salivary IgA under exam stress. Conclusions: Salivary IgA is reduced in response to exam stress. In addition, the rumination and personality traits may reduce or increase stress effects on the immune system, particularly the salivary IgA.

POTENCIAL DA ASSOCIAÇÃO Pisolithus microcarpus COM MUDAS DE Corymbia citriodora EM SOLO CONTAMINADO COM ZINCO

O uso de plantas com potencial de associação com microrganismos é uma prática frequente em solos contaminados por metais pesados, considerada de baixo custo e ambientalmente correta. O trabalho objetivou avaliar o crescimento do Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson e o efeito da inoculação com Pisolithus microcarpus UFSC-Pt116 em solo contaminado com Zn. O delineamento experimental foi inteiramente casualizado em arranjo fatorial (2 x 6), sendo com e sem inóculo e seis doses de Zn (0, 300, 600, 900, 1200 e 1500 mg kg-1 de solo), com seis repetições. As mudas foram inoculadas e cultivadas durante 90 dias em viveiro. Após 67 dias do transplante definitivo foi avaliado o percentual de colonização ectomicorrízica, a altura de planta, diâmetro do colo, número de folhas, índice de clorofila total, volume radicular, massa seca das folhas, da haste caulinar, radicular e total, relação massa seca aérea/massa seca radicular e a relação altura/diâmetro do colo. O percentual de colonização ectomicorrízica em Corymbia citriodora é estimulado pelo acréscimo de até 1412,21 mg kg-1 de Zn no solo. O Corymbia citriodora é tolerante a adição de até 1500 mg kg-1 de zinco em solo com 81% de argila, mesmo sem a inoculação com Pisolithus microcarpus. A análise de correlação canônica evidencia que a inoculação com P. microcarpus favorece a massa seca total, radicular e da parte aérea de Corymbia citriodora cultivado em solo com 81% de argila contaminada com 600 mg kg-1 de Zn.

Strategiaprosessi monikansallisessa yrityksessä

Tämän kandidaatintutkielman tavoitteena on tunnistaa strategiaprosessin eri vaiheet sekä kuvailla, miten prosessi toteutettiin tapausyritys Suominen Oyj:llä. Tavoitteina on myös analysoida, miten Suominen Oyj:n henkilöstö kokee oman suhteensa organisaatioon, sen strategiaan, tavoitteisiin ja arvoihin. Analyysin pohjalta pyritään muodostamaan kuva siitä, kuinka strategian implementoinnissa on onnistuttu. Lisäksi tarkastellaan, eroavatko nämä kokemukset eri maissa tapausyrityksessä. Tutkimuksessa käytetään sekä kvalitatiivisia että kvantitatiivisia tutkimusmenetelmiä. Suominen Oyj:n strategiaprosessista hankitaan informaatiota kahdella laadullisella puolistrukturoidulla teemahaastattelulla. Kvantitatiivisen analyysin kohteena puolestaan on tapausyrityksen yhdeksältäkymmeneltä ylimmässä asemassa työskentelevältä henkilöltä kerätty tilastollinen kyselydata, jota analysoidaan muun muassa Kruskal-Wallisin testillä sekä Spearmanin korrelaatioanalyysillä. Tutkielmassa muodostetaan kuva prosessista, jossa hyvin muotoiltu strategia sekä selkeät tavoitteet luovat pohjan strategian implementoinnille. Onnistuneen implementoinnin keinoja ovat muun muassa kehitysohjelmat, tarkka rekrytointi, tavoitteiden ja palkkioiden sitominen strategiaan, strategian kanssa yhteensopiva organisaatiokulttuuri, useamman eri hierarkiatason osallistuminen ja erilaisten kontrollijärjestelmien sekä implementointityökalujen hyödyntäminen. Havaitaan, että tapausyritys käyttää näistä keinoista useampaa. Yrityksen monikansallisuus vaikuttaa erityisesti organisaatiokulttuuriin sekä sisäiseen viestintään. Tutkielman kvantitatiivisen analyysin tulokset näyttävät, ettei maiden välillä ole tilastollisesti merkittäviä eroja siinä, miten henkilöstö kokee oman suhteensa tapausyritykseen, sen strategiaan, tavoitteisiin ja arvoihin. Kvantitatiivisen analyysin perusteella Suominen Oyj:n strategiaprosessi on onnistunut hyvin. Tutkimuksessa esitellään vielä muutamia kehitysajatuksia yritystä sekä mahdollisia jatkotutkimuksia varten.

Evaluation of the cytotoxic and genotoxic effects of benchmark multi-walled carbon nanotubes in relation to their physicochemical properties

To contribute with scientific evidence to the grouping strategy for the safety assessment of multi-walled carbon nanotubes (MWCNTs), this work describes the investigation of the cytotoxic and genotoxic effects of four benchmark MWCNTs in relation to their physicochemical characteristics, using two types of human respiratory cells. The cytotoxic effects were analysed using the clonogenic assay and replication index determination. A 48h-exposure of cells revealed that NM-401 was the only cytotoxic MWCNT in both cell lines, but after 8-days exposure, the clonogenic assay in A549 cells showed cytotoxic effects for all the tested MWCNTs. Correlation analysis suggested an association between the MWCNTs size in cell culture medium and cytotoxicity. No induction of DNA damage was observed after any MWCNTs in any cell line by the comet assay, while the micronucleus assay revealed that both NM-401 and NM-402 were genotoxic in A549 cells. NM-401 and NM-402 are the two longest MWCNTs analyzed in this work, suggesting that length may be determinant for genotoxicity. No induction of micronuclei was observed in Beas-2B cell line and the different effect in both cell lines is explained in view of the size-distribution of MWCNTs in the cell culture medium, rather than cell's specificities.

Síndrome de Burnout e autoeficácia: um estudo com profissionais de enfermagem de hospitais privados de Natal/RN

This research verifies the influence of the self-efficacy level on burnout syndrome incidence in relation to nursing professionals from private hospitals located in the Municipality of Natal, State of Rio Grande do Norte. The nature of the research was descriptive, and the used data analysis method was quantitative which was developed through SPSS computational package, version 17.0. The used instrument for the investigation was Maslach-Burnout Inventory (MBI), and the General Perceived Self-efficacy Scale (GPSES) was applied to a sample formed from 230 nursing professionals. The statistic techniques to data analysis were: frequency analysis; factor analysis; Cronbach.s alpha; Kaiser-Meyer-Olkin test (KMO); Bartlett efericity test; percentual analysis; Spearman rank correlation analysis; and simple regression. The achieved factors from factor analysis of MBI were the same, taking into account the dimensions which Maslach initially suggested to the instrument (emotional exhaustion, lack of personal realization, and depersonalization). However, one highlights that the low internal consistence of the depersonalization dimension can occur from people.s difficulty (caused by cultural aspects) of assuming this attitude in their work environment. Through GSE, it was achieved a factor which confirmed the unidimensionality showed by the author of the instrument. In relation to the syndrome incidence, it was verified that about 50% of the researched sample presented burnout syndrome evidence. Referring to self-efficacy level, about 65% of the researched sample presented low level of self-efficacy, what can be explained by the work characteristics of these professionals. In relation to the self-efficacy influence on the Burnout syndrome, it was verified that self-efficacy can be one of the aspects which influences occupational stress chronification (burnout), mainly to the personal realization dimension. Therefore, the researched hospital organizations need reflect about their attitudes in respect to their professionals, since the numbers showed a dangerous tendency regarding a predisposition to burnout syndrome of their staff, what implies not only a significant amount of individuals who can present high levels of emotional exhaustion, lack of personal realization, and depersonalization, but also the fact that this group presents low level of self-efficacy

Influência dos intermediários de distribuição de produtos turísticos no processo de decisão do meio de hospedagem pelo consumidor

This study examines the complex hotel buyer decision process in front of the tourism distribution channels. Its objective is to describe the influence level of the tourism marketing intermediaries, mainly the travel agents and tour operators, over the hotel decision process by the buyer-tourist. The data collection process was done trough a survey with three hundred brazilian tourists hosted in nineteen hotels of Natal, capital of Rio Grande do Norte, Brazil. The data analysis was done using some multivariate statistic techniques as correlation analysis, multiple regression analysis, factor analysis and multiple discriminant analysis. The research characterizes the hotel services consumers profile and his trip, and identifying the distribution channels used by them. Furthermore, the research verifies the intermediaries influence exercised over hotel buyer decision process, looking for identify causality relations between the influence level and the buyer profile. Verifies that information about hotels available on internet reduces the probability that this influence can be practiced; however it was possible identifying those consumers considers this information complementary and non-substitutes than the information from intermediaries. The characteristics of the data do not allow indentifying the factors that constraint the intermediaries influence neither identifying discriminant functions of the specific distribution channel choice by consumers. The study concludes that consumers don t agree in have been influenced by intermediaries or don t know if they have, still considering important to consult them and internet doesn t substitute their function as information source

Levels of vitamin D receptor and CYP24A1 in patients with end-stage renal disease.

Objective: This study was performed to detect the expression of vitamin D receptor (VDR) and cytochrome P450, family 24, subfamily A, polypeptide 1 (CYP24A1) in 24 end stage renal disease (ESRD) patients and 24 healthy controls. Method: In this study, 24 ESRD patients and 24 healthy controls were included. Results: In our study, the levels of VDR in patients with ESRD were reduced when compared with those from healthy controls (5.20±0.32 vs 8.59±1.03; P﹤0.01). However, the levels of CYP24A1 in ESRD patients were increased than those from healthy controls (50.18±21 vs 7.78±1.31; P﹤0.01). Correlation analysis showed that VDR levels were negatively correlated with CYP24A1 (r=-0.723; P﹤0.01). Conclusion: VDR levels were reduced and CYP24A1 levels were increased in patients with ESRD, and VDR levels were negatively correlated with CYP24A1.

Monitoring of specific activities of long-lived radioactive elements along the Mini- Okoro/Oginigba Creek, Port Harcourt

Presence and concentrations of radionuclides could be as a result of natural and human activities. This study examined the associations and differences among soil, sediment and water specific activities of long-lived radioactive element (LLRE). Gamma spectroscopy was used to measure the concentration of the LLRE along the Mini Okoro/Oginigba Creek, Port Harcourt. Specific activities of three selected LLRE were derived. Correlation analysis was carried out to examine associations among the specific activities across different substrates. A strong and a significant negative correlation exists between the specific activities of Water 40K and Soil 232Th (r =-0.721, p<0.05); Water 238U and Soil 238U (r = -0.717, p<0.05) and Water 40K and Sediment 238U (r=-0.69, p<0.05). Comparison using Mann-Whitney U test shows that, soil and sediment are similar in their specific activities with Z values of -0.408, -1.209 and -1.021 (p > 0.05) for 40K, 232Th and 238U respectively. The concentration of solid samples (soil and sediment) is different from the liquid (water) samples. These associations can be attributed to some specific underlying factors. And in other to understand them there is need for more studies.
