[Quality evaluation of Cnidii Fructus in commodity grade based on theory of "quality evaluation through morphological identification"].

From the perspective of market classification of Cnidii Fructus, this paper revealed the scientific connotation of evaluating the quality grade of Cnidii Fructus by its appearance traits. Thirty batches of Cnidii Fructus in different grades were selected as the research objects. The canonical correlation analysis and principal component analysis(PCA) were used to explore the measurement values of 15 appearance traits and intrinsic content indexes. The results of correlation analysis showed that except the aspect ratio, the 5 appearance trait indexes(length, width, 1 000-grain weight, broken grain weight proportion, and chroma) and 9 internal content indexes(the content of moisture, total ash, acid insoluble ash, osthole, imperatorin, 5-methoxy psoralen, isopimpinellin, xanthotoxin, and xanthotol) showed significant correlation to varying degrees. In addition, there was a significant positive correlation between the first typical variable U_1 composed of appearance traits and the first typical variable V_1 composed of internal content indexes(CR_1=0.963, P<0.01). The results of PCA showed that the classification results of appearance traits for 30 batches of Cnidii Fructus were consistent with the actual information of the samples. Under the same analysis conditions, 30 batches of Cnidii Fructus were reclassified by 9 groups of internal content indexes, and the analysis results were consistent. From the classification standard of the appearance traits of the system study, the statistical results of 6 appearance traits of Cnidii Fructus showed a correlation with grades. There was a good correlation between the appearance and the internal content of Cnidii Fructus, and the appearance quality effectively predicted the level of the internal content. There is a certain scientific basis for the quality classification of Cnidii Fructus by main appearance traits. Appearance classification can replace quality grading to realize the "quality evaluation through morphological identification" of Cnidii Fructus.

It's not just in my head: An intersectional, social and systems-based framework in gender and sexuality diversity.

BACKGROUND: The mental health and well-being of gender and sexuality diverse (GSD) people needs to be understood within a socio-political and cultural context. AIMS: In this paper, an intersectional, social and system-based framework for understanding the mental health and well-being of GSD people is presented, for practitioners within this field to consider GSD mental health experiences and challenges within context. MATERIALS AND METHODS: Starting with a consideration of the current landscape of understanding, pivotal theories and understandings within the field are outlined. The need for a framework that centralises intersectionality and broader systemic considerations is presented. RESULTS: The framework provided has an explicit focus on four key features: (1) intersectionality, (2) institutions, policies and laws, (3) people and groups and (4) social stories. DISCUSSION: Consideration of each of these 'circles of influence' can help practitioners to understand the multi-layered and intersectional experience of GSD folk and allows for an understanding of potential intervention at both an individual and systemic and societal level. CONCLUSION: Use of such a framework in practice goes above and beyond what is currently available by centralising the role and impact of such wider systemic variables through an intersectional lens. The framework can be applicable worldwide given its flexibility to consider and apply pertinent policies, laws, people, groups and social stories within a particular country or culture.
