Functionalized Magnetite Nanoparticles—Synthesis, Properties, and Bio-Applications

Abstract: Nanotechnology has generated tremendous hopes in recent years toward the design of advanced functional materials, especially in the bio-medical field. Nano-sized-materials such as magnetite nanoparticles display indeed fascinating physico-chemical properties that, if tuned properly, can be exploited to design new bio-diagnostic and therapeutic strategies as well as innovative biotechnology methodologies. Owing to their biocompatibility and excellent magnetic properties, magnetite nanocrystals have been the object of a tremendous amount of research in the last decade and numerous (bio)applications have been reported. Importantly, advances in the synthesis of magnetite nanoparticles enable excellent control over their size, shape, and composition. Despite these remarkable progresses, many issues remain to be overcome for these nanotechnology products to revolution the medical practice. The fine control and application of colloidal nanostructures such as magnetite nanoparticles in complex biological systems ...

Psychosocial safety climate: Development of the PSC-12.

Abstract: Psychosocial risks in the workplace have the potential for causing psychological and social harm that contributes toward the mental health disability burden. Psychosocial risks are influenced by macrolevel factors such as the psychosocial safety climate within the organization. This paper concerns the development and evaluation of a short instrument to measure psychosocial safety climate (PSC). PSC is conceived as an up-stream resource, and concerns senior management values and attitudes toward care and practices in relation to employee psychosocial well being. In a pilot sample (N 78) we used an iterative procedure incorporating regression analysis to reduce 26 items down to a parsimonious 12 item, four-factor scale (PSC-12). The PSC-12 was then assessed using confirmatory factor analysis and the scale validated in a second representative sample of Australian workers (N 398). The PSC-12 showed expected relationships with psychosocial risk factors (e.g., job demands, job resources), worker engagement and health, and work related outcomes (e.g., job satisfaction). We further confirmed the invariance of the factor coefficients and factor covariance across the two multioccupational samples using multigroup analysis. In a third organizational study (N 16 teams, 106 health care workers) we found that PSC showed group like psychometric properties, and team level PSC was associated with individual level psychological distress and work engagement. PSC showed incremental value beyond a physical safety measure. The results provide initial indications that the PSC-12 can be used across a range of occupations, and within organizations.
