Biometric relationships of ocular components in esotropic amblyopia

Purpose: To investigate the contribution of the individual ocular components, i.e. anterior chamber depth, lens thickness and vitreous chamber depth, to total axial length in patients with esotropic amblyopia. Methods: The study population consisted of 74 children, aged between 5 and 8 years: thirty-seven patients with esotropic amblyopia and 37 healthy volunteers (control group). The participants underwent a comprehensive ophthalmological examination, including cycloplegic refraction and A-scan ultrasonography. Anterior chamber depth, lens thickness, vitreous chamber depth and total axial length were recorded. Paired Student's t-tests were used to compare biometric measurements between amblyopic eyes and their fellow eyes and between right and left eyes in the control group. To evaluate the contribution of the ocular components to the total axial length, we report the individual components as a percentage of total axial length. Results: The comparison between amblyopic and fellow eyes regarding the individual contribution from ocular components to the total axial length revealed greater contribution from lens thickness (P=0.001) and smaller contribution from vitreous chamber depth (P=0.001) in amblyopic eyes, despite similar contribution from anterior chamber depth (P=0.434). The comparison between right and left eyes in the control group showed similar contributions from anterior chamber depth (P=0.620), lens thickness (P=0.721), and vitreous chamber depth (P=0.483). Conclusions: This study shows differences between amblyopic and non-amblyopic eyes when the total axial length is broken down into the individual contribution from the ocular components.

STRUCTURAL CHARACTERIZATION OF CANOPIES OF Eucalyptus spp. USING RADIOMETRIC DATA FROM TM/Landsat 5

Empirical approaches and, more recently, physical approaches, have grounded the establishment of logical connections between radiometric variables derived from remote data and biophysical variables derived from vegetation cover. This study was aimed at evaluating correlations of dendrometric and density data from canopies of Eucalyptus spp., as collected in Capao Bonito forest unit, with radiometric data from imagery acquired by the TM/Landsat-5 sensor on two orbital passages over the study site (dates close to field data collection). Results indicate that stronger correlations were identified between crown dimensions and canopy height with near-infrared spectral band data (rho(s)4), irrespective of the satellite passage date. Estimates of spatial distribution of dendrometric data and canopy density (D) using spectral characterization were consistent with the spatial distribution of tree ages during the study period. Statistical tests were applied to evaluate performance disparities of empirical models depending on which date data were acquired. Results indicated a significant difference between models based on distinct data acquisition dates.

Notas cartográficas do trabalho na Estratégia Saúde da Família: relações entre trabalhadores e população

Essa pesquisa-intervenção teve como objetivo cartografar os movimentos instituídos e instituintes presentes no trabalho da Estratégia Saúde da Família, no que tange a composição de suas práticas cuidativas. O referencial teórico metodológico fundamentou-se na análise institucional, linha esquizoanalítica. Foram realizados encontros grupais com uma equipe para discutir o modo como realizavam os cuidados coletivos em ação de educação permanente em saúde. Os sujeitos da pesquisa foram trabalhadores da equipe e estudantes em atividade acadêmica no serviço. A média de participação foi de doze pessoas por encontro, sendo que se desenvolveram oito encontros no período de março a julho de 2010. Os dados foram agrupados em dois estratos imanentes: as relações da equipe e a relação com os usuários. Os estratos apontaram para o atravessamento das instituições de educação, justiça e da divisão técnica e social do trabalho. A reflexão coletiva em grupo mostrou-se potente, para desnaturalizar processos instituídos e interrogar lugares, saberes e práticas.

Evolução da literatura de inovação em relações de cooperação: um estudo bibliométrico num período de vinte anos

Uma das principais características das relações de interação em busca de cooperação consiste na busca de novas formas de gestão produtiva e administrativa, condicionadas pela pressão por inovação. O objetivo deste trabalho é realizar uma análise da literatura, entre os anos de 1991 e 2010, sobre os temas inovação e cooperação. Para isso, os autores utilizaram o método de estudo bibliométrico e análise qualitativa de alguns dos trabalhos e referências. Foi realizada uma busca na base de dados ISI Web of Knowledge (Web of Science) com os tópicos relacionados à inovação e cooperação. Com base na análise das palavras-chave que mais apareceram nos artigos da amostra e na nomenclatura utilizada pela base de dados para codificar as áreas, foram identificadas as oito áreas que mais se relacionaram com a temática de pesquisa, sendo elas capacidade de absorção (absorptive capacity), alianças estratégicas, conhecimento, desempenho, gestão, inovação tecnológica, pesquisa e desenvolvimento, desenvolvimento de novos produtos e redes. Verificou-se que as publicações concentraram-se em apenas 17 periódicos, sendo que os quatro que mais publicaram foram: International Journal of Production Research, International Journal of Technology Management, Management Science e Technovation. As publicações cresceram a partir de 2000, com um pico em 2008. A crescente necessidade de interação entre entidades e de inovação, por meio da combinação de recursos internos e externos, justificam a análise da evolução da literatura.

Valor e vantagem competitiva: buscando definições, relações e repercussões

O tópico central que motiva o presente trabalho é o papel que o valor desempenha nas teorias de estratégia e que, apesar de ser considerado nas principais correntes de pensamento do campo, ainda apresenta indefinição. O objetivo é explorar as principais definições de valor e suas implicações para o desenvolvimento teórico no campo da Administração Estratégica, mais especificamente, para as investigações sobre vantagem competitiva sustentável. Ao trabalhar com conceitos de valor, como valor de uso, valor de troca, criação de valor, valor capturado, valor percebido e uso do valor, pode-se demonstrar que a formação e a sustentação de vantagem competitiva estão além do olhar predominantemente econômico. Elas necessitam ser complementadas por dimensões que atinjam o consumidor, alterando seu estado de espírito, seus desejos e suas emoções. A vantagem competitiva, nesse novo contexto, pode ser entendida como uma governança de um sistema de firmas que se alinham para a criação e a entrega de um valor de uso, e que se relaciona mutuamente para dividir o valor. Em um movimento recursivo, as informações e valores seguem a montante e a jusante da cadeia de firmas, formando um fenômeno complexo em que o processo de formação da estratégia é determinado por uma heurística própria de cada estrategista.

Psychiatric comorbidities in temporal lobe epilepsy: possible relationships between psychotic disorders and involvement of limbic circuits

OBJECTIVE: Mounting evidence suggests that the limbic system is pathologically involved in cases of psychiatric comorbidities in temporal lobe epilepsy (TLE) patients. Our objective was to develop a conceptual framework describing how neuropathological and connectivity changes might contribute to the development of psychosis and to the potential neurobiological mechanisms that cause schizophrenia-like psychosis in TLE patients. METHODS: In this review, clinical and neuropathological findings, especially brain circuitry of the limbic system, were examined together to enhance our understanding of the association between TLE and psychosis. Finally, the importance of animal models in epilepsy and psychiatric disorders was discussed. CONCLUSIONS: TLE and psychiatric symptoms coexist more frequently than chance would predict. Damage and deregulation among critical anatomical regions, such as the hippocampus, amygdala, thalamus, and the temporal, frontal and cingulate cortices, might predispose TLE brains to psychosis. Studies of the effects of kindling and injection of neuroactive substances on behavior and electrophysiological patterns may offer a model of how limbic seizures in humans increase the vulnerability of TLE patients to psychiatric symptoms.

Fenômenos alucinatórios auditivos em pacientes com zumbido: relações afetivas e aspectos depressivos

INTRODUÇÃO: Nos últimos anos, identificamos um número crescente de pacientes com zumbido que também referiam percepções repetidas de sons complexos, como músicas e vozes. Tais fenômenos alucinatórios nos instigaram a estudar suas possíveis relações com o psiquismo destes pacientes. OBJETIVOS: avaliar se os fenômenos alucinatórios dos pacientes com zumbido têm relação com psicose e/ou depressão, além de esclarecer seu conteúdo e função no psiquismo. MÉTODO: Dez sujeitos (8 mulheres, idade média de 65,7 anos), selecionados por otorrinolaringologistas, foram avaliados pela mesma psicóloga por meio de entrevista semi-dirigida, Escala para Depressão de Hamilton e entrevistas psicanalíticas. RESULTADOS: Nenhum dos pacientes apresentou relação dos fenômenos auditivos com psicose, mas sim com aspectos depressivos. O discurso dos pacientes evidenciou que os fenômenos apresentam funções inconscientes na vida afetiva de cada um. A forte tendência à rememoração/repetição de fatos/situações desagradáveis foi marcante em todos os casos, tendendo a exacerbar o incômodo com o zumbido, com os fenômenos alucinatórios e a piorar aspectos depressivos. CONCLUSÕES: Há uma importante relação entre zumbido, fenômenos alucinatórios e depressão, sustentada na rememoração persistente de fatos/situações que causam sofrimentos psíquicos. O conhecimento destes achados representa mais um passo em direção à necessidade de particularizar o tratamento deste subgrupo de pacientes com zumbido, envolvendo equipe multidisciplinar. Prospectivo.

Influências das relações intrafamiliares no comportamento de crianças que frequentam creches públicas de alfenas

Nos últimos anos, as organizações sociais e familiares se modificaram, tornando as creches mais requisitadas pela população. Nosso objetivo foi compreender as influências das relações intrafamiliares no comportamento das crianças de 0 a 3 anos, que frequentam creches, por meio das experiências vivenciadas por seus monitores. Pesquisa qualitativa, utilizando a Trajetória Fenomenológica, com entrevista de 12 monitores de seis creches públicas municipais. Como categorias: reprodução de comportamentos apreendidos no ambiente familiar; integração família-creche como facilitadora do trabalho desempenhado pelos monitores; déficit de cuidados higiênicos oferecidos pela família. Estudos futuros poderão promover melhorias nas ações dos cuidadores frente às necessidades infantis, apontando para uma melhor qualidade de vida das crianças, contribuindo para o desenvolvimento de todo o seu potencial.

Dinâmica de constituição e eventos geradores em redes de colaboração científica: estudo exploratório entre relações de coautoria e em bancas de defesas de teses e dissertações na área da Ciências da Comunicação.

O estudo da dinâmica de constituição de uma rede visa identificar que tipos de eventos ocorreram nas conexões entre os nós que levaram a formação da estrutura atual da rede em análise. Entender esses eventos é entender as formas específicas e estratégias de conectividade que deram origem a rede. O presente trabalho tem por objetivo analisar esses eventos geradores com foco específico em redes de colaboração científica, considerando relações de coautoria e participação em bancas de defesas de teses e dissertações. Analisando mais de 11.000 documentos específicos da área das Ciências da Comunicação, propomos dois tipos característicos de eventos que pretendem explicar a dinâmica de formação das redes em análise.

Relationships Past and Present: Examining the Impact of One's Relationship with His/her Opposite-sex Parent on His/her Attitudes Toward and Engagement in Hookup Culture

Hooking up has become a common and public practice on university campuses across the country. While much research has determined who is doing it, with whom they are doing it, and what they are hoping to get out of it, little work has been done to determine what personal factors motivate students to participate in the culture. A total of 407 current students were surveyed to assess the impact of one’s relationship with his/her opposite-sex parent on his/her attitudestoward and engagement in hookup culture on campus. Scores were assigned to the participants to divide them into categories of high and low attachment with their parent. It was hypothesizedthat heterosexual students who do not perceive themselves as having a strong, close, positive relationship with their opposite-sex parent would be more likely to engage in or attempt to engage in casual sexual behavior. This pattern was expected to be strongest for women on campus. Men and women differed in their reasons for hooking up, with whom they hook up, to what they attribute the behaviors of their peers, and what they hope to gain from their sexual interactions. Effects of parent-child relationships were significant only for women who reported hooking up because “others are doing it,” men’s agreement with the behavior of their peers, and women’s overall satisfaction with their hookups. Developmental, social, and evolutionary perspectives are employed to explain the results. University status was determined to be most telling of the extent to which a student is engaged in hookup culture.

Genetic relationships of Aeromonas strains inferred from 16S rRNA, gyrB and rpoB gene sequences

Genetic relationships among bacterial strains belonging to the genus Aeromonas were inferred from 16S rRNA, gyrB and rpoB gene sequences. Twenty-eight type or collection strains of the recognized species or subspecies and 33 Aeromonas strains isolated from human and animal specimens as well as from environmental samples were included in the study. As reported previously, the 16S rRNA gene sequence is highly conserved within the genus Aeromonas, having only limited resolution for this very tight group of species. Analysis of a 1.1 kb gyrB sequence confirmed that this gene has high resolving power, with maximal interspecies divergence of 15.2 %. Similar results were obtained by sequencing only 517 bp of the rpoB gene, which showed maximal interspecies divergence of 13 %. The topologies of the gyrB- and rpoB-derived trees were similar. The results confirm the close relationship of species within the genus Aeromonas and show that a phylogenetic approach including several genes is suitable for improving the complicated taxonomy of the genus.

LINKAGE RELATIONSHIPS AMONG PROTEIN-CODING LOCI IN FISHES OF THE GENUS XIPHOPHORUS

Inbred strains of three species of fishes of the genus Xiphophorus (platyfish and swordtails) were crossed to produce intra- and interspecific F(,1) hybrids, which were then backcrossed to one or both parental stocks. Backcross hybrids were used for the analysis of segregation and linkage of 33 protein-coding loci (whose products were visualized by starch gel electrophoresis) and a sex-linked pigment pattern gene. Segregation was Mendelian for all loci with the exception of one instance of segregation distortion. Six linkage groups of enzyme-coding loci were established: LG I, ADA --6%-- G(,6)PD --24%-- 6PGD; LG II, Est-2 --27%-- Est-3 --0%-- Est-5 --23%-- LDH-1 --16%-- MPI; LG III, AcPh --38%-- G(,3)PD-1 (GUK-2 --14%-- G(,3)PD-1 is also in LG III, but the position of GUK-2 with respect to AcPh has not yet been determined); LG IV, GPI-1 --41%-- IDH-1; LG V, Est-1 --38%-- MDH-2; and LG VI, P1P --7%-- UMPK-1 (P1P is a plasma protein, very probably transferrin).^ Sex-specific recombination appeared absent in LG II and LG IV locus pairs; significantly higher male recombination was demonstrated in LG I but significantly higher female recombination was detected in LG V. Only one significant population-specific difference in recombination was detected, in the G(,6)PD - 6PGD region of LG I; the notable absence of such effects implies close correspondence of the genomes of the species used in the study. Two cases of possible evolutionary conservation of linkage groups in fishes and mammals were described, involving the G(,6)PD - 6PGD linkage in LG I and the cluster of esterase loci in LG II. One clear case of divergence was observed, that of the linkage of ADA in LG I. It was estimated that a minimum of (TURN)50% of the Xiphophorus genome was marked by the loci studied. Therefore, the prior probability that a new locus will assort independently from the markers already established is estimated to be less than 0.5. A maximum of 21 of the 24 pairs of chromosomes could be marked with at least one locus.^ Only the two LG V loci showed a significant association with a postulated gene controlling the severity of a genetically controlled melanoma caused by abnormal proliferation of macromelanophore pigment pattern cells. The independence of melanotic severity from all other informative markers implies that one or at most a few major genes are involved in control of melanotic severity in this system. ^

Longitudinal relationships between prospective memory, executive functions, and metacognition in young elementary school children

Prospective Memory (PM), executive functions (EF) and metacognition (MC) are relevant cognitive abilities for everyday functioning. They all seem to develop gradually in childhood and appear to be theoretically closely related; however, their empirical links remain unclear, especially in children. As a recent study revealed significant cross-sectional links between PM and EF, and a weaker but close link between PM and MC in 2nd graders (Spiess, Meier, & Roebers, submitted), this study focused on their short-term relationships and on their development. 119 children (MT1 =95 months, SDT1, = 4.8 months) completed the same tasks (one PM, three EF, one MC task) twice with a time-lag of 7 months. T-tests showed significant improvements in all tasks, except in the updating task. Different structural equation models were contrasted (AMOS); the best fitting model revealed that PMT2 was similarly predicted by PMT1 (r = .33) and EFT1 (r = .34). Additionally, EFT1 predicted MCT2 (r = .44), chi2(118, 119) = 128.91, p = .23, TLI = .968, CFI = .978, RMSEA = .028. Results show that PM, EF, and MC develop during childhood and also demonstrate that they are linked not only cross-sectionally, but longitudinally. Findings are discussed in a broader developmental framework.

Sibling relationships in the family of a child with a burn injury

Purpose. Understanding siblings' experiences after a major childhood burn injury was the purpose of this mixed method, qualitative dominant study. The following research questions guided this project: How do siblings describe the impact of a major childhood burn injury experience? How do sibling relationship factors of warmth/closeness, relative status/power, conflict, and rivalry further clarify their relationship and their experience after a major burn injury? ^ Methods. A mixed method, qualitative dominant, design was implemented to understand the sibling experiences in a family with a child suffering from a major burn injury. Informants were selected from patients with childhood burn injuries attending the reconstructive clinic at a Gulf coast children's specialty hospital. The qualitative portion used the life story method, a narrative process, to portray the long-term impact on sibling relationships. A "case" represents a family unit and could be composed of one or multiple family members. Participants from 22 cases (N = 40 participants) were interviewed. Interviews were conducted in person and via telephone. The quantitative portion, or the embedded part of this mixed method design, used the Sibling Relationship Questionnaire Revised (SRQ-R) to conduct an additional structured interview and acquire scoring data. It was postulated that the SRQ-R would provide another perspective on the sibling experience and expand the qualitative data analysis. Thematic analysis was implemented on the qualitative interview data including the qualitative data from the interviews structured on the SRQ-R. Additionally, scores on the SRQ-R were tabulated to further describe the cases. ^ Results. The overall thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Areas of normalization as well as the process of adjustment were the major themes. Areas of normalization were found in play and other activities, in school and work, and in family relations with their siblings and their parents. The process of adjustment in the sibling relationship was described as varied, involved school and work re-entry, and might even change their life perspective. Further analysis included an examination of the cases in which more than one person were interviewed and completed the SRQ-R. Participants from five ( n = 11) of six cases (n = 14), scored above 3.0 on the five-point scale on the Warmth/Closeness construct, indicating they perceived the sibling relationship as close. Five participants scored high on the Conflict construct and four participants scored high on the Rivalry construct. Finally, Relative Status/Power was low or negative in the six cases (n = 13). ^ Conclusions/implications. These findings suggest the importance of returning to normalcy for many of the families and the significance of sibling relationships on the process. Some of these families were able to use this major life event in a positive way to promote normalization. ^
