Coordinated Development of the Marine Environment and the Marine Fishery Economy in China, 2011–2020

The marine environment is the material basis for the survival and development of fishery resources, and changes in the marine environment affect the fishery economy. Therefore, against the background of sustainability and environmental uncertainty, it is important to investigate the development of the marine environment and the marine fishery economy to improve the quality of both. Taking the panel data for 11 coastal cities in China from 2011 to 2020, we use several methods, including the entropy method, a coupling harmonious degree model, and a Tobit model, to measure the marine-environment quality and marine-fishery-economy quality, their coordination, and the factors affecting that coordination. We find that (1) the marine-environment quality and marine-fishery economy quality show a significant upward trend over time, but they are spatially unbalanced, with obvious interprovincial differences. (2) Coordination between the marine-environment quality and marine-fishery-economy quality has risen steadily, but the level of coordination is still low, remaining at the primary level in most areas. (3) The important factors affecting coordination between the marine-environment quality and marine-fishery-economy quality include the strength of the marine fishery industry, scale of the marine fishery economy, production capacity of marine fisheries, marine-environment quality, and quality of the marine environment and its resources. In light of these findings, we should increase the coordination between the marine-environment quality and marine-fishery-economy quality by upgrading the marine fishery industry, modernizing marine fisheries, linking the environmental governance of marine and land areas, and strengthening the ecological construction of the marine environment

Mentoring as a complex adaptive system - a systematic scoping review of prevailing mentoring theories in medical education.

BackgroundEffective mentorship is an important component of medical education with benefits to all stakeholders. In recent years, conceptualization of mentorship has gone beyond the traditional dyadic experienced mentor-novice mentee relationship to include group and peer mentoring. Existing theories of mentorship do not recognize mentoring's personalized, evolving, goal-driven, and context-specific nature. Evidencing the limitations of traditional cause-and-effect concepts, the purpose of this review was to systematically search the literature to determine if mentoring can be viewed as a complex adaptive system (CAS).MethodsA systematic scoping review using Krishna's Systematic Evidence-Based Approach was employed to study medical student and resident accounts of mentoring and CAS in general internal medicine and related subspecialties in articles published between 1 January 2000 and 31 December 2023 in PubMed, Embase, PsycINFO, ERIC, Google Scholar, and Scopus databases. The included articles underwent thematic and content analysis, with the themes identified and combined to create domains, which framed the discussion.ResultsOf 5,704 abstracts reviewed, 134 full-text articles were evaluated, and 216 articles were included. The domains described how mentoring relationships and mentoring approaches embody characteristics of CAS and that mentorship often behaves as a community of practice (CoP). Mentoring's CAS-like features are displayed through CoPs, with distinct boundaries, a spiral mentoring trajectory, and longitudinal mentoring support and assessment processes.ConclusionRecognizing mentorship as a CAS demands the rethinking of the design, support, assessment, and oversight of mentorship and the role of mentors. Further study is required to better assess the mentoring process and to provide optimal training and support to mentors

Reproducibility of fluorescent expression from engineered biological constructs in E. coli

We present results of the first large-scale interlaboratory study carried out in synthetic biology, as part of the 2014 and 2015 International Genetically Engineered Machine (iGEM) competitions. Participants at 88 institutions around the world measured fluorescence from three engineered constitutive constructs in E. coli. Few participants were able to measure absolute fluorescence, so data was analyzed in terms of ratios. Precision was strongly related to fluorescent strength, ranging from 1.54-fold standard deviation for the ratio between strong promoters to 5.75-fold for the ratio between the strongest and weakest promoter, and while host strain did not affect expression ratios, choice of instrument did. This result shows that high quantitative precision and reproducibility of results is possible, while at the same time indicating areas needing improved laboratory practices.Peer reviewe
