Regional Adoption of Business-to-Business Electronic Commerce in China: Role of E-Readiness

Adoption of B2B e-commerce is a powerful driver of economic success in developed and developing countries. However, adoption rates in developing countries lag far behind. This paper draws on the Perceived eReadiness Model and research on the influence of inter-organizational relationships and economic-cultural contexts to explain the importance of three factors—inter-organizational power dependence, cooperativeness, and regional economic-cultural differences—for achieving higher levels of Internet-based Electronic Data Interchange (EDI) in the developing country of China. We employ survey data to empirically test both the individual and joint influence of these factors. The findings suggest that beyond intra-organizational and external factors, managers and policy makers wanting to promote Internet-based EDI adoption in developing countries must also account for the inter-organizational relationships of firms and the economic and cultural circumstances of the regions in which they operate

The current situation and future conceptualization of power in industrial markets

This article offers overview of research on power in industrial and business markets, conducted through the 10 articles in the special issue. These contributions are catalysts for defining the history, context, current situations, and future developments and prospects for power in the business world. Therefore, this article presents a conceptualization and understanding of power, using the special issue as a lens through which to view past antecedents, present understanding, and future directions. In addition to studies that mine past and present academic and practical rationales for power, the empirically based contributions test and explore power. This article identifies and thematically draws out and labels the principal manifestations across these contributions, to link origins with current principal foci and identify the most likely emphases of theory and practice for the future business-to-business arena

Phenotypic and molecular characterization of IMP-producing Enterobacterales in Spain: Predominance of IMP-8 in Klebsiella pneumoniae and IMP-22 in Enterobacter roggenkampii

Objectives: Little is known about IMP-producing Enterobacterales (IMP-Ent) in Europe. We analyzed at genomic and phenotypic level IMP-Ent isolates circulating in Spain in a 9-year period. Materials and methods: IMP-Ent isolates submitted to our reference laboratory were included. Antibiotic susceptibility was performed using microdilution method (EUCAST), and IMP-carbapenemase activity was measured with carbapenemase inhibitors, the β-CARBA method, the modified Hodge test (MHT), and the modified carbapenemase inhibition method (mCIM). All isolates collected were sequenced for high-resolution single-nucleotide polymorphism (SNP) typing, core genome multilocus sequence typing (cgMLST), and resistome analysis. Results: Fifty IMP-Ent isolates, collected from 19 hospitals in 13 Spanish provinces, were detected: Klebsiella pneumoniae (IMP-Kpn) (24; 48%), Enterobacter roggenkampii (13; 26%), Enterobacter hormaechei (8, 16%), Klebsiella oxytoca (two; 4%), Enterobacter asburiae (one, 2%), Serratia marcescens (one; 2%) and Escherichia coli (one; 2%). All isolates were positive by the MHT and β-CARBA tests; 48 (96%) were mCIM positive; 12 (24%) and 26 (52%) displayed positive inhibition with dipicolinic (meropenem) and EDTA (ertapenem), respectively. Five IMP-carbapenemase types were identified: IMP-8 (22; 44%), IMP-22 (17; 34%), IMP-13 (7; 14%), IMP-28 (two; 4%), and IMP-15 (two; 4%), predominating IMP-8 in K. pneumoniae and IMP-22 in E. roggenkampii. IMP-28 was exclusively identified in K. oxytoca and IMP-15 in E. hormaechei. Predominant STs were ST405 (29.2%), ST15 (25%) and ST464 (20.8%) in IMP-Kpn; ST96 (100%) in E. roggenkampii and ST182 (62.5%) in E. hormachei. Colistin and amikacin were the most active non-carbapenem antibiotics against IMP-Ent. Conclusion: IMP-Ent isolates remain infrequent in Spain, although in recent years have been circulating causing nosocomial outbreaks, being IMP-8-producing K. pneumoniae and IMP-22-producing E. roggenkampii the most frequently detected in this study. Inhibition with EDTA or dipicolinic acid presented false negative results in some IMP-producing strains. Active microbiological and molecular surveillance is essential for a better comprehension and control of IMP-Ent dissemination.This research was supported by grants from the Instituto de Salud Carlos III (numbers PI18CIII/00030 and PI21CIII/00039).

Histopathological placental lesions in mild gestational hyperglycemic and diabetic women

Objective: To investigate and compare the incidence of histopathological placental lesions in mild gestational hyperglycemia, gestational diabetes and overt diabetes at term and preterm gestation.Research design and methods: One-hundred-and-thirty-one placental samples were collected from Diabetes mellitus (DM) positive screened patients. Two diagnostic tests, glycemic profile and 100 g oral glucose tolerance test (OGTT) in parallel identified 4 groups normoglycemic, mild gestational hyperglycemia (MGH), gestational DM (GDM) or overt DM (DM). Placental tissue specimens and sections from 4 groups were obtained by uniform random sampling and stained with hematoxylin-eosin.Results: Placentas from MGH group presented 17 types of histopathological change and higher rates of syncytial nodes and endarteritis. GDM placentas presented only nine types of histopathological change, high rates of dysmaturity, low rates of calcification and no syncytial nodes. Overt DM placentas showed 22 types of histopathological change, 21 of which were present in the preterm period. There were histopathological similarities between MGH and DM placentas, but the former exhibited a higher incidence of endarteritis, which has been described as a post-mortem phenomenon.Conclusion: Our results confirmed that the distinct placental changes associated with DM and MGH depend on gestational period during which the diabetic insult occurs. It may reasonably be inferred that subclinical maternal hyperglycemia during pregnancy, as showed in MGH group, is responsible for increased placental endarteritis, a postmortem lesion in the live fetus

Value co-creation: The role of actor competence

YesAdopting a Service-Dominant Logic lens, recent research within industrial marketing contexts increasingly recognizes the role of operant resources in value co-creation. Incumbent within operant resources is actor competence. Despite this, an investigation into the role of actor competence in value co-creating processes is scant and the competence literature, in general, has tended to concentrate on specialized knowledge and skills based interpretations that potentially restrict our understanding of the construct. To address this gap, this research adopts a phenomenological approach to explore perceived behavioral attributes of competent actors. Findings confirm two broad behaviorally based conceptualizations of competence: 1) extra-role behavior demonstrated through organizational citizenship behavior, and 2) in-role behavior demonstrated through understanding of work, and engagement behavior. To this end, the contribution of this research is twofold. First and from a theoretical perspective, it offers empirical insights into a relational based framework of competency within industrial marketing contexts. Second, and from a pragmatic perspective, this framework may aid managers in developing a broader understanding of actor competence and how such competencies may be enhanced within the workplace to optimize value co-creation

VACUUM SYSTEM OF HIRFL’S CYCLOTRONS

HIRFL has 2 cyclotrons: a sector focus cyclotron (SFC)<br />and a separate sector cyclotron (SSC). SFC was built in<br />1957. In the past 50 years, the vacuum system of SFC has<br />been upgraded for three times. The vacuum chamber was<br />redesigned to double-deck at the third upgrade. The<br />working pressure in beam chamber was improved from<br />10-6mbar to 10-8mbar. SFC has delivered Pb, Bi and U<br />beams in the past few years since the last upgrading of its<br />vacuum chamber. SSC began to operate in 1987. The<br />vacuum chamber of SSC has a volume of 100m3. 8<br />cryopumps keep the pressure from 5&times;10-7mbar to 8&times;10-<br />8mbar depending on the used pump numbers (2~8). In the<br />past 20 years, because of the contamination of oil vapour<br />and leaks occurred in some components inside the SSC<br />vacuum chamber, the vacuum condition has worsened<br />than the beginning. It is a big problem to accelerate the<br />heavier ions. The upgrade for the SSC vacuum system<br />will be an urgent task for us. The rough pumping systems<br />of both SFC and SSC have been rebuilt recently. As a<br />result, the oil vapour in two cyclotrons will be eliminated<br />and the vacuum condition of them will be improved.<br />A new small cyclotron will be built in HIRFL as an<br />injector of the Heavy Ion Therapy Facility in Lanzhou<br />(HITFiL). The brief introduction of the vacuum system<br />design is given in the paper
