Supply Chain Management: Supplier Performance and Firm Performance

This research examines the relationship between supply chain management (SCM) practices, supplier performance, and company performance. The results provide empirical evidence that selected purchasing practices and customer relation practices are strongly ssociated with the perceived financial and market success of firms responding to the survey

A new acquisition model for the next disaster: overcoming disaster federalism issues through effective utilization of the Strategic National Stockpile

Using primary data collected from interviews with federal and state government officials and secondary data related to PPE distribution and state healthcare statistics, we discovered evidence that the use of the Strategic National Stockpile (SNS) to distribute personal protective equipment to state and local agencies in need during the height of COVID-19 was indeed poorly designed to cope with the COVID-19 emergency, leaving many states with shortages of badly needed medical supplies. As a result, many states struggled to organize an uncoordinated procurement response – which we suggest is due to federalism issues. To overcome federalism challenges and increase future disaster preparedness, we recommend four necessary reforms to the SNS that include 1) the incorporation of uncompensated industry experts into SNS administration, 2) the provision of an emergency production board for times of crisis, 3) elevated political leadership for the SNS, 4) improvement of federal-state supply chain governance

Tools and Techniques of Quality Management: An Empirical Investigation of Their Impact on Performance

An investigation of quality management at an operational rather than a strategic level is described. Using a survey of senior quality personnel, data were collected on four aspects of quality: management; quality tools; documentation; and the dimensions of quality that companies measure. Regression analysis confirms suggestions in the literature that company performance is positively affected by a culture in which quality is ingrained. Moreover, it identifies positive relationships between several widely used operational practices and company performance

Sourcing complexity factors on contractual relationship: Chinese suppliers’ perspective

To reduce cost and gain competitive advantage, original equipment manufacturers (OEMs) around the world have continued their aggressive sourcing from China. However, sourcing in China has never been a straightforward process and OEMs face both tangible and intangible sourcing complexities with significant negative impact on both expected positive benefits and their contractual relationships with the Chinese suppliers. We developed sourcing complexity model using comprehensive literature review and multiple case studies in various industries to understand the suppliers’ views on sourcing complexity in China. We employed Analytic hierarchy process technique to prioritise identified complexity factors and to derive managerial insights. Our results indicate that tangible complexity factors highly influence the Chinese suppliers’ contractual relationship with OEM’s. Number of suppliers available to OEM’s to procure a component is identified as a primary dominating tangible factor, while differentiation in technical capabilities and operational practices between OEMs and suppliers represents the second biggest issue for Chinese suppliers in establishing contractual relationship with OEM’s

Idiopathic benign retroperitoneal cyst: a case report

<p>Abstract</p> <p>Introduction</p> <p>Retroperitoneal cysts are uncommon, with an estimated incidence of 1/5750 to 1/250,000.</p> <p>Case presentation</p> <p>A male patient was admitted with an abdominal pain, jaundice and fever. Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery.</p> <p>Conclusion</p> <p>Retroperitoneal cysts are very rare, and most of the time they are discovered incidentally. Patients may be asymptomatic or present with abdominal pain, referred pain to the legs or weight loss. Imaging may help diagnose these lesions, but surgery is the keystone in confirming the diagnosis. This case is very rare and very educational as it highlights an unusual presentation of a benign retroperitoneal cyst. In our patient, the course of the disease was unique as the patient presented with jaundice.</p

Potentiality in Biology

We take the potentialities that are studied in the biological sciences (e.g., totipotency) to be an important subtype of biological dispositions. The goal of this paper is twofold: first, we want to provide a detailed understanding of what biological dispositions are. We claim that two features are essential for dispositions in biology: the importance of the manifestation process and the diversity of conditions that need to be satisfied for the disposition to be manifest. Second, we demonstrate that the concept of a disposition (or potentiality) is a very useful tool for the analysis of the explanatory practice in the biological sciences. On the one hand it allows an in-depth analysis of the nature and diversity of the conditions under which biological systems display specific behaviors. On the other hand the concept of a disposition may serve a unificatory role in the philosophy of the natural sciences since it captures not only the explanatory practice of biology, but of all natural sciences. Towards the end we will briefly come back to the notion of a potentiality in biology

Quality Management Initiatives in Europe: an Empirical Analysis according to Their Structural Elements

"This is an Accepted Manuscript of an article published by Taylor & Francis in Total Quality Management and Business Excellence on 10 June 2010, available online: http://wwww.tandfonline.com/10.1080/14783363.2010.483064."In recent years, managers have opted for implementing Quality Management in their firms. The market offers different alternatives for QM implementation, such as EFQM model, ISO standards, Malcolm Baldrige or the recent Six Sigma methodology. Implementation difficulty of each initiative varies from case to case. This article designs a criterion for choosing among four alternatives (Quality Control, EFQM, Six Sigma and ISO 9000), according to the degree of development required for the elements that structure the alternatives. To do so, using an ANOVA analysis and mean comparison T-tests, it analyses 234 organizations in Europe that have implemented the four alternatives mentioned and observes the degree of development of nine of the elements that compose them. From the research, one can conclude that Quality Control is the simplest initiative, followed by ISO 9000 and, finally, the EFQM model and Six Sigma methodology

Application of In Vivo Induced Antigen Technology (IVIAT) to Bacillus anthracis

In vivo induced antigen technology (IVIAT) is an immuno-screening technique that identifies bacterial antigens expressed during infection and not during standard in vitro culturing conditions. We applied IVIAT to Bacillus anthracis and identified PagA, seven members of a N-acetylmuramoyl-L-alanine amidase autolysin family, three P60 family lipoproteins, two transporters, spore cortex lytic protein SleB, a penicillin binding protein, a putative prophage holin, respiratory nitrate reductase NarG, and three proteins of unknown function. Using quantitative real-time PCR comparing RNA isolated from in vitro cultured B. anthracis to RNA isolated from BALB/c mice infected with virulent Ames strain B. anthracis, we confirmed induced expression in vivo for a subset of B. anthracis genes identified by IVIAT, including L-alanine amidases BA3767, BA4073, and amiA (pXO2-42); the bacteriophage holin gene BA4074; and pagA (pXO1-110). The exogenous addition of two purified putative autolysins identified by IVIAT, N-acetylmuramoyl-L-alanine amidases BA0485 and BA2446, to vegetative B. anthracis cell suspensions induced a species-specific change in bacterial morphology and reduction in viable bacterial cells. Many of the proteins identified in our screen are predicted to affect peptidoglycan re-modeling, and our results support significant cell wall structural remodeling activity during B. anthracis infection. Identification of L-alanine amidases with B. anthracis specificity may suggest new potential therapeutic targets

Delineation of Culicoides species by morphology and barcode exemplified by three new species of the subgenus Culicoides (Diptera: Ceratopogonidae) from Scandinavia

BACKGROUND: Culicoides biting midges (Diptera: Ceratopogonidae) cause biting nuisance to livestock and humans and are vectors of a range of pathogens of medical and veterinary importance. Despite their economic significance, the delineation and identification of species where only morphology is considered, as well as the evolutionary relationships between species within this genus remains problematic. In recent years molecular barcoding has assisted substantially in the identification of biting midges in the multiple entomological survey projects which were initiated in many European countries following the bluetongue outbreak in 2006–2009. These studies revealed potentially new species and “species-complexes” with large genetic and morphological variability. Here we use molecular barcoding, together with morphological analysis, to study subgenus Culicoides Latreille from Scandinavia with focus on three potentially new species. METHODS: Biting midges were collected at various sites in Denmark and Sweden. Culicoides specimens were described by variation of a fragment of their cytochrome c oxidase subunit 1 (COI) gene sequence and wing, palp and antennal characters. RESULTS: It is shown that three new species initially separated by DNA barcoding with mitochondrial COI can be distinguished by morphological characters. In this context a key to Scandinavian subgenus Culicoides using wing and maxillary palp characters is presented. The key is including the three new species Culicoides boyi, Culicoides selandicus and Culicoides kalix. CONCLUSION: Three new species of Culicoides biting midges were identified and could be identified by both molecular and morphological differences. Evaluation of differences between and within taxa of biting midges using COI barcode yielded a rough estimate of species delineation; interspecies differences across Culicoides subgenera approaches 20%, whereas intraspecies differences are below 4% and in most cases below 1%.
