El cuidado de los ancianos en el entorno familiar : valoración de los recursos de apoyo mediante grupos de discusión

Introduction: in the present study several collectives with knowledge of the reality of family care of the elderly assessed several socia and healthcare resources and suggested several possibilities for improvement. Method: four discussion groups were used as a data collection technique. The groups were composed of caregivers, representatives-users of associations for the elderly, experts in geriatrics, and social services professionals. Results: the various discussion groups positively evaluated the Home Help Service, the Support Teams of the Home Service Programs, Interdisciplinary Community Health Workers Units, Daytime Care Centres, and the Family Rest Programme but suggested some changes to all of them. The discussion groups also indicated the need to improve the material, economic and emotional assistance given to caregivers and asked for training, institutional coordination, anddissemination of information about available resources and assistance. Conclusions: some changes are required to improve the current social and health resources available to families caring for the elderly within the family unit. Among the suggestions for improvement proposed by the participants, many are useful and could easily be applied, whereas others provide an interesting starting point for debate and reflection. Knowledge and understanding of the situation of caregiving families, based on their own experiences and those of the people who know them, is in itself sufficient to initiate and implement changes to provide resources appropriate to their needs

Risk perception and stages of smoking acquisition = Percepción de riesgo y etapas de iniciación en el consumo de tabaco

The purpose of this descriptive survey was to investigate the risk perceptions of smoking in a sample of 1,510 Spanish adolescents(49.1% males; mean age = 14.03; SD = 1.28). In addition, the present research categorised adolescents into one of the fourstages of smoking acquisition, as described by the Transtheoretical Model of Change (TMC): Precontemplation (notthinking about trying smoking in the next 6 months), Contemplation (thinking about trying smoking in the next 6 months), Preparation (thinking about starting smoking in the next 30 days) and Action (smokers), by gender and age. The results showed that age and risk perceptions are important variables in the progression through the stages of change towards regular tobacco consumption (Action stage). These results clearly demonstrate the importance of starting antismoking campaigns at an early age to prevent smoking acquisition or the thought of starting in the near future. These findings also highlight the need to continuously remind adolescents about the negative consequences of smoking

El proceso de valoración de programas preventivos en drogodependencias

Drug preventive interventions have been the specific object of this type of evaluation. The present study describes stages involved in evaluating drug preventive programs and contemplates the main considerations to take into account to make this type of evaluation more effective in line with recommendations by the main programs evaluation guides

Jóvenes internados bajo la LO 5/2000 reguladora de la responsabilidad penal del menor. Estudio de casos

This research focuses on life trajectories and desistance from crime processes in a case-study qualitative sample of six offenders from 18 to 21 years old sentenced to penal custody in Barcelona, Spain.The theoretical framework comprises systemism (Mario Bunge, 2000, 2006), the life-course perspective (Elder, 1994, 2007), transition to adulthood (Casal et al., 2006) and desistance from crime as a process (Maruna, 2001; Sampson and Laub, 2003; Bottoms and Shapland, 2010; Cid and Martí, 2011).Information was collected through in-depth personal interviews and analysed through content analysis. Results show the importance of attachment to family and school institutions, as well as an effective professional training skill programme at the correctional facility to achieve a law-abiding lifestyle at adulthood.

Análisis psicométrico de la escala multidimensional de autoconcepto AF5 en una muestra de adolescentes y adultos de Cataluña

Psychometric analysis of the AF5 multidimensional scale of self-concept in a sample of adolescents and adults in Catalonia. The aim of this study is to carry out a psychometric study of the AF5 scale in a sample of 4.825 Catalan subjects from 11 to 63 years-old. They are students from secondary compulsory education (ESO), from high school, middle-level vocational training (CFGM) and from the university. Using a principal component analysis (PCA) the theoretical validity of the components is established and the reliability of the instrument is also analyzed. Differential analyses are performed by gender and normative group using a 2 6 factorial design. The normative group variable includes the different levels classifi ed into 6 sub-groups: university, post-compulsory secondary education (high school and CFGM), 4th of ESO, 3rd of ESO, 2nd of ESO and 1st of ESO. The results indicate that the reliability of the Catalan version of the scale is similar to the original scale. The factorial structure also fi ts with the original model established beforehand. Signifi cant differences by normative group in the four components of self-concept explored (social, family, academic/occupational and physical) are observed. By gender, signifi cant differences appear in the component of physical self-concept, academic and social but not in the family component

Psychological and Family Factors Associated with Suicidal Ideation in Pre-Adolescents

To assess the psychological and family factors associated with suicidal ideation in preadolescent children, we studied a sample of 361 students, average age 9 years old. Twogroups were formed, on the basis of the presence (n = 34) or absence (n = 44) of suicidal ideation. Suicidal ideation was assessed with the Children’s Depression Inventory and the Children’s Depression Rating Scale-Revised. Depression, hopelessness, self-esteem, and perceived family environment were compared in both the suicidal ideation and the control groups. Students with suicidal ideation generally presented greater depressive symptoms and hopelessness, and lower self-esteem and family expressiveness, although there weredifferences both between sexes, and when the variable depression was controlled. Identifying these risk factors in pre-adolescents may have an impact on prevention of suicidal behavior at higher risk ages

¿Qué entienden los jóvenes universitarios por monogamia y sexo sin penetración, como estrategias preventivas de la transmisión sexual del virus del SIDA? = What university students understand by monogamy and sex without penetration as preventive strategies of sexual transmission of AIDS virus?

Monogamy and sex without penetration are behaviors recommended by the WHO to avoid AIDS virus sexual transmission. Seven hundred and fifty university students from 18 to 25 years (67.7% women) were surveyed and they were asked to give a maximum of three free definitions of the words monogamy and sex without penetration to prevent AIDS virus sexual transmission. Their participation was voluntary and anonymous. Although the majority of the answers was correct, there was a considerable percentage of wrong answers, either for monogamy (3.7% masturbation; 2.1% to have many partners; 0.9% homosexual relations), or for sex without penetration (20.5% oral sex; 1.1% anal coitus; 0.8% coitus without orgasm; 0.4% coitus interruptus). Some definitions or examples differ by gender. The amount of wrongs or incomplete answers put researchers on the alert about insufficient preventive knowledge in a population with a high educational level

SEASONAL CHEMICAL COMPOSITIONS OF THE ESSENTIAL OILS OF TWOEugenia SPECIES AND THEIR ACARICIDAL PROPERTIES

The leaf essential oils of Eugenia lutescens Cambess andEugenia langsdorffii O. Berg, collected in the rainy (RS) and dry seasons (DS), were extracted by hydrodistillation and then characterized by a gas chromatography-flame ionization detector and a gas chromatography-mass spectrometer. The potential acaricidal activity and oviposition deterrence of these oils were evaluated against Tetranychus urticae . The oil yields were higher in the RS for E. lutescens, while those forE. langsdorffii were higher in the DS. α-Pinene and β-pinene were determined to be the major constituents of the oils fromE. lutescens, while bicyclogermacrene, spathulenol, and β-caryophyllene predominated in E. langsdorffii . Seasonal variations in the oils were primarily related to chemical diversity, and E. lutescens was more affected than was E. langsdorffii . The E. langsdorffii oil collected in the DS was most toxic to the spider mite, while the oils of E. lutescens and E. langsdorffii collected in the RS drastically reduced its egg quantities. This study successfully determined the periods of greater oil production and acaricidal activity.

Cytopathological characterization of Mal de Río Cuarto virus in corn, wheat and barley

The Mal de Río Cuarto disease is caused by Mal de Río Cuarto virus (MRCV) transmitted by Delphacodes kuscheli. Comparative studies were carried out on the cytopathological alterations produced by MRCV in corn (Zea mays), wheat (Triticum aestivum) and barley (Hordeum vulgare), as seen with a transmission electron microscope. Corn plants were infected with viruliferous D. kuscheli collected from the endemic disease area (i.e. Río Cuarto County, Córdoba, Argentina). For the viral transmission to small grain cereal plants, laboratory rared insects were used. In this case, the inoculum source was wheat and barley plants infected with MRCV isolate grown in a greenhouse. Leaf samples with conspicuous symptoms were collected: enations and size reduction in corn; crenatures, swelling veins and dark green color in small grain cereals. Viral infection was corroborated by DAS-ELISA. Viroplasms containing complete and incomplete virus particles and fibrillar material were found in the cytoplasm of infected cells in all species. Mature virions were between 60 and 70 nm diameter. In wheat and barley, viroplasms and dispersed particles were observed only in phloem, while in corn virions were also found in cells of the bundle sheath. Crystalline arrays of particles were detected in corn enation constitutive cells. Tubular inclusions were found only in wheat samples. The three species showed abnormalities in the chloroplasts of affected cells. The results showed that MRCV cytopathology has similarities with other viruses from the genus Fijivirus, family family Reoviridae, but slight differences depending upon the host plant.

Determinação e distribuição de ácido ascórbico em três frutos tropicais

O método clássico iodimétrico foi utilizado para determinação de ácido ascórbico (AA) nos frutos araçá (Eugenia sp.), acerola (Malphigia sp.) e laranja (Citrus sinenses). Os frutos coletados foram classificados como verdes, verde- amarelados ou amarelos conforme a cor superficial. Os frutos foram levados ao laboratório e resfriados para minimizar a oxidação de AA. Os teores determinados de AA para o araçá evidenciaram que há uma gradiente de concentração entre as partes superior e inferior dos frutos, sendo a concentração em C2 (concentração de ácido ascórbico na parte inferior do fruto) sempre maior que a concentração em C1 (concentração de ácido ascórbico na parte superior do fruto ligada ao pedúnculo). Comportamento semelhante também foi observado para acerolas e laranjas, que apresentaram uma concentração média na parte superior de 17,7 mg g-1 e 0,612 mg L-1 e na parte inferior 19,6 mg g-1 e 0,665 mg L-1, respectivamente. Pelos resultados obtidos pode-se concluir que os três frutos apresentam uma distribuição heterogênea de AA e essa variação é mais pronunciada para frutos verdes, i.e. frutos menos adequados para consumo.

Flora de importância polinífera para Apis mellifera (L.) na região de Viçosa, MG

Procurou-se conhecer a flora de importância polinífera para Apis mellifera (L.) na região de Viçosa, MG, em período de entressafra de mel, entre agosto e dezembro de 2005. O experimento foi realizado em dois apiários distintos, cada um com cinco colmeias. As cargas retidas nos coletores de pólen instalados nas colmeias foram analisadas quanto à origem botânica. As plantas em floração no entorno dos apiários foram coletadas e identificadas. A maioria das plantas de importância polinífera para abelhas na região de Viçosa era nativa, localizada em jardins e com hábito arbóreo. Pela análise palinológica, verificou-se que espécies como Anadenanthera colubrina, Arecaceae sp., Baccharis dracunculifolia, B. melastomaefolia, Coffea spp., Emilia sagittata, Eugenia uniflora, Mikania cordifolia, M. hirsutissima, Myrcia fallax, Psidium guajava, Vernonia condensata, V. diffusa, V. lanuginosa e V. mariana são potenciais recursos poliníferos a serem utilizados no período de entressafra do mel. Os resultados indicaram a importância de plantas localizadas em áreas abertas para o forrageamento de pólen por A. mellifera e confirmaram o potencial polinífero da região estudada, durante o período de entressafra do mel.

Corte foliar e tempo de transplantio para o uso de plântulas do sub-bosque na restauração florestal

O uso de plântulas da regeneração natural tem sido recomendado como estratégia para produção de mudas visando à restauração florestal, contudo muitos aspectos técnicos desse método ainda carecem de investigação científica. O objetivo deste trabalho foi avaliar o efeito da redução da área foliar e do transplantio imediato na sobrevivência e crescimento de mudas de espécies arbóreas produzidas a partir de plântulas obtidas da regeneração natural. Plântulas de Esenbeckia leiocarpa (Rutaceae), Eugenia ligustrina (Myrtaceae) e Maytenus salicifolia (Celastraceae), obtidas em remanescente de vegetação secundária de Floresta Estacional Semidecidual em Bofete, SP, foram extraídas do solo e submetidas aos tratamentos: I) redução de 50% da área de cada folha e transplantio imediato; II) nenhuma redução de área das folhas e transplantio imediato; III) redução de 50% da área de cada folha, manutenção das plântulas em água e transplantio 24 h após a coleta; e IV) nenhuma redução de área das folhas, manutenção das plântulas em água e transplantio 24 h após a coleta. As mudas foram avaliadas com relação à sobrevivência e ao crescimento em altura, ao longo de oito meses. Os resultados evidenciaram que nem o corte das folhas ou a manutenção das plântulas dentro de recipientes com água por 24 h antes do transplantio afetaram os parâmetros avaliados. Assim, para as espécies estudadas a redução da área foliar e o transplantio imediato são desnecessários para a produção de mudas em viveiro a partir de plântulas obtidas da regeneração natural.

Substratos e níveis de água no potencial germinativo de sementes de uvaia

Objetivou-se neste trabalho avaliar o substrato e a disponibilidade de água no potencial germinativo das sementes de uvaia (Eugenia pyriformis). Os substratos avaliados foram: areia (A), latossolo + areia (L + A) (1:1), latossolo + areia + cama de frango semidecomposta (L + A1 + CF) (1:1:0,5), latossolo + areia + cama de frango semidecomposta (L + A2 + CF) (1:2:0,5), latossolo + Bioplant® (L + B) (1:1) aliados aos seguintes níveis de irrigação 25, 50, 75 e 100% da capacidade de retenção de água. As maiores porcentagens de emergência e melhor crescimento de plântulas foram observados no substrato latossolo + areia + cama de frango (1:2:0,5), na capacidade de retenção de água de 50%.

Manejo agrícola no refúgio de vida silvestre de una: agroflorestas como uma perspectiva de conservação

Este estudo investiga os tipos de manejo e o perfil socioeconômico relacionado a estes, nas propriedades rurais do Refúgio de Vida Silvestre de Una. Tem-se como pressuposto de que as agroflorestas sucessionais são as mais favoráveis para conservação do bioma Mata Atlântica, inclusive na escala de paisagem. Portanto, objetiva-se conhecer os aspectos socioeconômicos associados à adoção de um tipo de manejo e sua inserção na paisagem. Para tanto, foram realizadas entrevistas em 73 propriedades, entre janeiro e maio de 2011. Os dados sobre os agrossistemas foram classificados em tipos de manejo: convencional, tradicional, orgânico e agroflorestal. Os resultados apontaram a predominância do tipo de manejo tradicional entre as propriedades. O perfil socioeconômico encontrado é compatível com as características do tipo de manejo predominante, o tradicional. Observaram-se no manejo tradicional: maior contribuição da mão de obra familiar e menor ocorrência de fonte de renda proveniente de trabalho rural para terceiros. A capacitação para atividade agrícola foi a única característica socioeconômica que apresentou maior importância para o manejo agroflorestal. Na paisagem, os resultados apontaram para a necessidade de adequação das práticas utilizadas nos agroecossistemas tradicionais aos objetivos da conservação do bioma, pois 39% das propriedades estão a uma distância de 350 m dos fragmentos, considerada máxima para que ocorra a conectividade estrutural, e possuem esse tipo de manejo.
