A História da Alimentação: balizas historiográficas

Os M. pretenderam traçar um quadro da História da Alimentação, não como um novo ramo epistemológico da disciplina, mas como um campo em desenvolvimento de práticas e atividades especializadas, incluindo pesquisa, formação, publicações, associações, encontros acadêmicos, etc. Um breve relato das condições em que tal campo se assentou faz-se preceder de um panorama dos estudos de alimentação e temas correia tos, em geral, segundo cinco abardagens Ia biológica, a econômica, a social, a cultural e a filosófica!, assim como da identificação das contribuições mais relevantes da Antropologia, Arqueologia, Sociologia e Geografia. A fim de comentar a multiforme e volumosa bibliografia histórica, foi ela organizada segundo critérios morfológicos. A seguir, alguns tópicos importantes mereceram tratamento à parte: a fome, o alimento e o domínio religioso, as descobertas européias e a difusão mundial de alimentos, gosto e gastronomia. O artigo se encerra com um rápido balanço crítico da historiografia brasileira sobre o tema

Cryptic genetic structure and copy-number variation in the ubiquitous forest symbiotic fungus Cenococcum geophilum.

Ectomycorrhizal (ECM) fungi associated with plants constitute one of the most successful symbiotic interactions in forest ecosystems. ECM support trophic exchanges with host plants and are important factors for the survival and stress resilience of trees. However, ECM clades often harbour morpho-species and cryptic lineages, with weak morphological differentiation. How this relates to intraspecific genome variability and ecological functioning is poorly known. Here, we analysed 16 European isolates of the ascomycete Cenococcum geophilum, an extremely ubiquitous forest symbiotic fungus with no known sexual or asexual spore-forming structures but with a massively enlarged genome. We carried out whole-genome sequencing to identify single-nucleotide polymorphisms. We found no geographic structure at the European scale but divergent lineages within sampling sites. Evidence for recombination was restricted to specific cryptic lineages. Lineage differentiation was supported by extensive copy-number variation. Finally, we confirmed heterothallism with a single MAT1 idiomorph per genome. Synteny analyses of the MAT1 locus revealed substantial rearrangements and a pseudogene of the opposite MAT1 idiomorph. Our study provides the first evidence for substantial genome-wide structural variation, lineage-specific recombination and low continent-wide genetic differentiation in C. geophilum. Our study provides a foundation for targeted analyses of intra-specific functional variation in this major symbiosis

Convergent and discriminant validity and utility of the DSM–5 Levels of Personality Functioning Questionnaire (DLOPFQ): Associations with medical health care provider ratings and measures of physical health

The ability to evaluate patients’ level of personality functioning in assessing personality disorders has become increasingly important since the DSM–5 Section III hybrid system of personality disorder assessment was released. One measure developed to assess this criterion is the DSM–5 Levels of Personality Functioning Questionnaire (DLOPFQ; Huprich et al., 2017), which assesses individuals’ self and other representations in four domains—self-direction, identity, empathy, and intimacy—across two contexts—work or school and relationships. A sample of 140 psychiatric and internal medicine outpatients were administered several questionnaires, including the DLOPFQ. Provider ratings also were obtained for level of functioning and DSM–5 pathological personality traits. Several of the DLOPFQ scales were significantly correlated with self-reported and provider-reported measures of DSM–5 trait domains and levels of functioning, along with self-reported measures of effortful control, overall physical and mental health, and well-being. Certain DLOPFQ scales and subscales were associated with provider ratings of likeability and patient contact with the providers. However, relatively modest validity coefficients, as well as poor discriminant validity of domain scales, indicate further research and measure refinement might be needed. It is concluded that, although further research is necessary, the DLOPFQ could be useful for understanding patients’ personality pathology in clinical settings

Introduction of the DSM-5 levels of personality functioning questionnaire

With the introduction in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) of a hybrid system of personality disorder assessment, the ability to assess patients\u27 traits, as well as their level of personality functioning, has become increasingly important. To assess this criterion, the DSM-5 Levels of Personality Functioning Questionnaire (DLOPFQ) was developed. The DLOPFQ assesses individuals\u27 self-impairments and other impairments in several domains (self-direction, identity, empathy, and intimacy) and across 2 contexts (work/school and relationships). A sample of 140 psychiatric and medical outpatients was administered the DLOPFQ and several other measures to assess its reliability and construct, incremental, and discriminant validity. The internal consistency and convergence with validation measures yielded generally meaningful and expected results. Several DLOPFQ scales and subscales were significantly correlated with measures of DSM-5 trait domains and levels of personality functioning. DLOPFQ scales also correlated with self-reported ratings of overdependence, detachment, healthy dependency, and overall mental health and well-being. The DLOPFQ also predicted interpersonal and general functioning beyond DSM-5 trait domains. These results support the reliability and validity of the DLOPFQ, which appears to be suitable for clinical use and warrants ongoing study
