One challenge in the area of supply chain management has been achieving sustainable compliance with labour rights throughout the entire production chain, including lower tiers of production. This article inquires specifically around sub-contracting, especially what is a brand’s or a buyer’s responsibility regarding workers’ rights beyond its first tier of suppliers. In-depth literature on this iss

In this paper, we present a photoemission study of the interaction of Cu, Ag and Au with clean single-crystal Bi2CaSr2Cu2O8 superconductor surfaces. Both the valence-band and the Bi 5d, O 1s and Sr 3d core levels were monitored for all overlayers. Cu, Ag and Au were deposited as consecutively thicker layers starting with a third of a monolayer and progressing in steps up to a deposition in the ran

The ordered c(2×2) Na on Al(100) and (3 × 3) R30°K on Al(111) structures formed at either 100 K or at room temperature are studied by high-resolution core-level spectroscopy. For both systems equal alkali coverages are found at these two temperatures. The core-level spectra, however, show strong changes with temperature. This behavior leads to the surprising conclusion that annealing at room tempe

The surface core-level shift of the Pd(100) single-crystal surface has been measured from high-resolution Pd 3d core-level spectra. The surface atoms are found to have 0.44+or-0.03 eV lower binding energy than the bulk atoms. The result is compared with theoretical estimates.

The presentation of the United Nation’s (UN) Global Compact (hereinafter “GC” or “Compact”) in a book dedicated to monitoring mechanisms requires an urgent clarification: the GC itself is not a monitoring mechanism meant to deliver corporate accountability. Still, the Compact is an important hub in a broader network of initiatives dealing with responsible business practices and corporate accountab

For the CSR movement the challenge is broadly speaking to make responsible business practices both effective and sustainable in the long run, communicate them credibly to third parties, and institutionalise them more widely in the business community. In this article, I address three main themes where I think more clarity would enable CSR to evolve to a new level and achieve its promising potential

There is currently a widespread societal expectation for businesses to respect and support human rights. The apparent simplicity of this expectation contrasts sharply against the difficulty of specifying with precision the boundaries of corporate social responsibilities (CSR). This Article argues that the basis of these difficulties is the uncertainty regarding the responsibility of a business for

This collection gathers the more important instruments dealing with the relationships of business with a range of topics such as labor rights, security issues, environmental protection, anti-corruption, good governance, poverty alleviation and development, which all have important human rights dimensions. The premise for this selection is that business has both responsibilities and opportunities t

An experimental culture system was designed with the purpose of studying matrix synthesis and cell proliferation in the deep flexor tendon of the rabbit fore-paw. Special attention was paid to differences between three consecutive defined segments of the tendon from the region of the tendon sheath. There were two fibrocartilaginous areas in the tendon, one in the dorsal part of the proximal segmen

Implantation of demineralized bone matrix in rodents elicits a series of cellular events leading to the formation of new bone inside and adjacent to the implant. This process is believed to be initiated by an inductive protein present in bone matrix. It has been suggested that local growth factors may further regulate the process once it has been initiated. This investigation was designed to study

Flexor tendon segments were incubated in a diffusion chamber in the subcutis of rabbits. Tendons incubated up to 6 weeks in the diffusion chamber showed proliferating and migrating cells from the epitenon cell layer as well as viable endotenon cells. Explants frozen in liquid nitrogen prior to incubation showed no signs of extrinsic cell contamination and remained non-viable indicating that no cel

We measured the levels of cartilage proteoglycan (PG) fragments in knee joint synovial fluid obtained from patients with previous trauma of the knee, early gonarthrosis, or pyrophosphate synovitis, and in age-matched control subjects. During the initial 3-4 weeks after rupture of the anterior cruciate ligament or the meniscus (confirmed by arthroscopy), markedly increased PG fragment levels were f

Rat chondrosarcoma chondrocytes were labeled with [3H]serine or [3H]mannose as a precursor. Intracellular proteoglycan core protein precursor was purified from cell lysates by immunoprecipitation with polyclonal antibodies against the hyaluronic acid-binding region, followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The core precursor was eluted from the gels and treated with a

The structure, biosynthesis, and metabolism of proteoglycans in the HL-60 human promyelocytes were studied by metabolic labeling in culture with [35S]sulfate, [3H]glucosamine, [3H]serine, and [3H]leucine. These cells synthesize a single predominant species of intracellular proteoglycan with an approximate molecular weight of 100,000. The cells contain about 1 μg of proteoglycan/million cells. The

Flexor tendons have an intrinsic ability for repair, with a capacity to metabolize matrix components and to proliferate. To identify factors with the potential of affecting those abilities, the effects of recombinant human insulin-like growth factor (rhIGF-I), insulin and fetal calf serum (FCS) on the synthesis of proteoglycan, collagen, and non-collagen protein and cell proliferation were investi

The effects of human recombinant insulin-like growth factor-I (rhIGF-I, 50 ng/ml) on matrix metabolism in the deep flexor tendon from the tendon sheath region of the rabbit were studied in explants cultured for 3 weeks. Tendon segments cultured in medium supplemented with fetal calf serum (FCS) exhibited proliferation of the superficial cell layers. Synthesis of proteoglycan and non-collagen prote

High tibial osteotomy was performed for medial gonarthrosis in 28 patients. Preoperatively, and at 3, 12, and 24 months after surgery, clinical and radiographic examinations were made, and joint-fluid samples were aspirated. Arthroscopy was performed preoperatively and at 24 months. Immunoassay of proteoglycan epitope in joint fluid showed an increase in concentration at all times as compared with

Demineralized bone matrix from young and adult monkeys was implanted intramuscularly for 6 weeks in athymic rats and adult monkeys. Cartilage and bone induction was evaluated by histology and calcium content. In the athymic rat, most implants induced cartilage or bone. In the monkeys, cartilage was formed only on rare occasions and there was no sign of bone formation. We conclude that (a) adult mo

Implantation of demineralized bone matrix in rodents elicits a series of cellular events leading to the formation of new bone inside and adjacent to the implant. This process is believed to be initiated by an inductive protein present in bone matrix, and local growth factors may further regulate the process. We have previously shown that local application of recombinant human basic fibroblast grow

Segments of the deep flexor tendon of the rabbit were exposed to air; the effects of dehydration on in vitro synthesis of proteoglycan, collagen, non-collagenous protein, and cell proliferation were compared with tendon segments that were kept moist with physiologic saline. After 20 min of expo-sure to air, the tendons lost half and after 40 min all of their ability to synthesize matrix components
