Circular supply chain management: a bibliometric analysis-based literature review

Purpose Supply chain management (SCM) research has contributed to the transition to a circular economy (CE). Still, confusions exist on the related terms, and no review has mapped out the development trends in the domain. This research clarifies the boundaries of the relevant concepts. Then, it conducts a comprehensive review of the circular SCM (CSCM) literature and identifies opportunities for future research. Design/methodology/approach Using relevant keywords, 1,130 journal articles published in December 31, 2021 were identified. Unlike the published reviews, which mainly relied on content analysis, this review uses bibliometric analysis tools, including citation analysis, co-citation analysis and cluster analysis. The review identifies general trends, influential researchers, high-impact publications, citation patterns and established and emergent research themes. Findings The extant CSCM literature includes five prominent clusters: (1) reverse channel optimization; (2) CSCM review and empirical studies; (3) closed-loop supply chain (CLSC) and consumers; (4) CLSC and inventory management and (5) CLSC and reverse logistics (RL). Significant research gaps exist in the use of secondary and longitudinal data, a wider range of theories, mixed-methods, multi-method, action research and behavioral experiment. The least researched topics include zero waste, industrial symbiosis, circular product design, sourcing and supply management and reuse. Originality/value This is the first bibliometric analysis-based literature review on CSCM. It clarifies the interrelated supply chain sustainability terms and thus reduces related confusion. It offers insights into the patterns in the CSCM literature and suggests important research directions

Electroretinography Reveals Difference in Cone Function between Syndromic and Nonsyndromic USH2A Patients

Usher syndrome is an inherited and irreversible disease that manifests as retinitis pigmentosa (RP) and bilateral neurosensory hearing loss. Mutations in Usherin 2A (USH2A) are not only a frequent cause of Usher syndrome, but also nonsyndromic RP. Although gene-and cell-based therapies are on the horizon for RP and Usher syndrome, studies characterizing natural disease are lacking. In this retrospective analysis, retinal function of USH2A patients was quantified with electroretinography. Both groups had markedly reduced rod and cone responses, but nonsyndromic USH2A patients had 30 Hz-flicker electroretinogram amplitudes that were significantly higher than syndromic patients, suggesting superior residual cone function. There was a tendency for Usher syndrome patients to have a higher distribution of severe mutations, and alleles in this group had a higher odds of containing nonsense or frame-shift mutations. These data suggest that the previously reported severe visual phenotype seen in syndromic USH2A patients could relate to a greater extent of cone dysfunction. Additionally, a genetic threshold may exist where mutation burden relates to visual phenotype and the presence of hearing deficits. The auditory phenotype and allelic hierarchy observed among patients should be considered in prospective studies of disease progression and during enrollment for future clinical trials.National Institute of HealthNational Cancer InstituteResearch to Prevent Blindness (RPB)RPB, New York, NY, USARPBInternational Council of Ophthalmology - Retina Research FoundationNIHTistou and Charlotte Kerstan FoundationSchneeweiss Stem Cell Fund, New York StateFoundation Fighting Blindness New York Regional Research CenterCrowley Family FundGebroe Family FoundationColumbia Univ, Dept Ophthalmol, Med Ctr, Jonas Childrens Vis Care, New York, NY 10027 USAColumbia Univ, Dept Ophthalmol, Med Ctr, Bernard & Shirlee Brown Glaucoma Lab, New York, NY 10027 USANew York Presbyterian Hosp, Edward S Harkness Eye Inst, New York, NY 10034 USASuny Downstate Med Ctr, Brooklyn, NY 11203 USAUniv Fed Espirito Santo, Dept Ophthalmol, Vitoria, BrazilUniv Fed Sao Paulo, Dept Ophthalmol, Sao Paulo, BrazilColumbia Univ, Dept Biostat, New York, NY USAUniv Montreal, Dept Ophthalmol, Montreal, PQ, CanadaShanghai Jiao Tong Univ, Sch Med, Xin Hua Hosp, Dept Ophthalmol, Shanghai, Peoples R ChinaColumbia Univ, Inst Human Nutr, Dept Pathol & Cell Biol, Stem Cell Initiat CSCI,Coll Phys & Surg, New York, NY 10032 USAStanford Univ, Dept Ophthalmol, Om Lab, Byers Eye Inst, Palo Alto, CA 94304 USAUniv Fed Sao Paulo, Dept Ophthalmol, Sao Paulo, BrazilWeb of Scienc

Влијание на кинеската традиционална медицина за лекување на болки во грбот

Болките во грбот претставуваат еден од почестите проблеми со кој се соочуваат луѓето во нивниот секојдневен живот и се најчеста причина за значајни загуби на работните денови. Хроничните болки во грбот станаа една од најчестите причини за боледување кај вработените на возраст под 45 години. Кога луѓето остануваат дома заради повреда во грбот, само 65% се враќаат на работа по една недела и речиси 14% се сеуште отсутни по еден месец. И ако некој е на боледување подолго од шест месеци, има само 50% шанси да се врати на работа. Поголемиот дел од болките во грбот се должат на иритација на зглобовите, или притисок врз лигаментите и мускулите од заболени дискови или шилци. Притисокот врз нервните завршетоци исто така може, да доведе до болки во грбот и нозете. Многу фактори можат да ги влошат болките во грбот. Доживеаниот стрес, преголемата тежина, неправилното држење на телото и лошата кондиција можат да ги влошат или продолжат болките во грбот. Постојат огромен број причини за појава на болки во грбот, но најчесто се работи за една од следниве: механички проблеми, повреди, стекнати болести, инфекции и тумори и емоционален стрес. Кинеската традиционална медицина се развивала во денешна Кина, потоа била пренесена во Јапонија, Кореа, Монголија, Виетнам, Филипините и др. Од физиолошка гледна точка, древните лекари го разгледувале човечкиот организам како сложен систем, во кој елементите се функционално поврзани. Тие си го претставиле телото како “монада“, поделено на два еднакви дела Jин и Јан. Јан го претставува машкиот дел или татковото потекло, кој се изразува во секое светло, активно, суво, топло, творечко, постојано. Jин е од мајчинско потекло кое се изразува како влажно, ладно, темно, сокриено, пасивно. Здравото тело олицетворение на хармонијата помеѓу Јан и Jин. Дисбалансот помеѓу нив доведува до болест. Друга претстава од страна на старата источна медицина е взаемното дејство помеѓу петте елементи – симболи на физичката состојба на природата: дрвото – црн дроб, оган – срце, земја – панкреас, метал – бели дробови, вода – бубрези. Древните научници откриле точки кои ги нарекле космички точки. Боцкањето со игли, загревањето со мокса, притисокот и масажата во тие точки доведува до подобрување на состојбата. Исто така била откриена и т.н. космичка енергија или Чи која што се движи по невидливите канали - меридијаните. Меридијаните се 12 парни кои се расположени по двете страни на телото и два непарни, кои на краевите се поврзани со внатрешните клонови еден со друг и така енергијата Чи циркулира низ телото во еден затворен систем. Секој меридијан има најголема активност по 2 часа дневно. Кај болков синдром меридијаните со нивните билошко – активни точки (БАТ) се место на надворешна симптоматика и перку нив може да се дијагностицира. Точките стануваат болни, со покачена температура и тврди. Треба да се знае дека точките не се поставени во близина на болниот орган, туку тие се наоѓаат по меридијаните. Акупресурата како метода има предност затоа што е безболна и безкрвна процедура, не е потребна специјална техника и лесно се применува. Таа се употребува за покачување на заштитните сили на организмот, за тонизирање, за подобрување и одржување на општата состојба, се употребува и како профилактички метод. Може да се употреби и со други терапевтски методи: класична или сегментарна масажа, климато терапија, балнео терапија. Клучни зборови Акупресура – метод на лекување со притискање. Јин – вид на енергија во телото кое го претставува женскиот пол Јан – вид на енергија во телото кое го претставува машкиот по

Expert range maps of global mammal distributions harmonised to three taxonomic authorities

Aim: Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroecology. We provide global range maps for the native ranges of all extant mammal species harmonised to the taxonomy of the Mammal Diversity Database (MDD) mobilised from two sources, the Handbook of the Mammals of the World (HMW) and the Illustrated Checklist of the Mammals of the World (CMW). Location: Global. Taxon: All extant mammal species. Methods: Range maps were digitally interpreted, georeferenced, error-checked and subsequently taxonomically aligned between the HMW (6253 species), the CMW (6431 species) and the MDD taxonomies (6362 species). Results: Range maps can be evaluated and visualised in an online map browser at Map of Life (mol.org) and accessed for individual or batch download for non-commercial use. Main conclusion: Expert maps of species' global distributions are limited in their spatial detail and temporal specificity, but form a useful basis for broad-scale characterizations and model-based integration with other data. We provide georeferenced range maps for the native ranges of all extant mammal species as shapefiles, with species-level metadata and source information packaged together in geodatabase format. Across the three taxonomic sources our maps entail, there are 1784 taxonomic name differences compared to the maps currently available on the IUCN Red List website. The expert maps provided here are harmonised to the MDD taxonomic authority and linked to a community of online tools that will enable transparent future updates and version control.Fil: Marsh, Charles J..

Finding needles in haystacks:Linking scientific names, reference specimens and molecular data for Fungi

DNA phylogenetic comparisons have shown that morphology-based species recognition often underestimates fungal diversity. Therefore, the need for accurate DNA sequence data, tied to both correct taxonomic names and clearly annotated specimen data, has never been greater. Furthermore, the growing number of molecular ecology and microbiome projects using high-throughput sequencing require fast and effective methods for en masse species assignments. In this article, we focus on selecting and re-annotating a set of marker reference sequences that represent each currently accepted order of Fungi. The particular focus is on sequences from the internal transcribed spacer region in the nuclear ribosomal cistron, derived from type specimens and/or ex-type cultures. Reannotated and verified sequences were deposited in a curated public database at the National Center for Biotechnology Information (NCBI), namely the RefSeq Targeted Loci (RTL) database, and will be visible during routine sequence similarity searches with NR_prefixed accession numbers. A set of standards and protocols is proposed to improve the data quality of new sequences, and we suggest how type and other reference sequences can be used to improve identification of Fungi.The Intramural Research Programs of the National Center for Biotechnology Information, National Library of Medicine and the National Human Genome Research Institute, both at the National Institutes of Health.http://www.ncbi.nlm.nih.gov/bioproject/PRJNA177353am201
