Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- From Introduction: In this chapter, occupational health and safety is approached from the viewpoints of both Human Factors and Ergonomics and standardization, including management systems standards. The field of Occupational Health and Safety (OHS) is summarily characterized, and a historical perspective of its evolution is given, in relationship to Human Factors and Ergonomics (HFE). While several components of what makes the field of OHS up today pre-existed as specialized fields before, the foundation of the discipline of HFE (following World War II)—and some of the genesis of HFE, OHS, and HFE—have developed as two distinct, although somewhat overlapping, areas of ac-tivity. Links and commonalities can be found today between the two. Environmental conditions (such as noise, climate, or lighting) are an example of an area that is dealt with within the discipline of HFE and is also a central concern of OHS. While inadequate postures and movements at work and psychosocial factors impinge on OHS, HFE is equipped with knowledge and methods to perform the design of work and to deal with these work design factors. Regarding legislation, regulations, and standardization, OHS has gained a head start compared to HFE (the Occupational Safety and Health Act of 1970 in the U.S.A., the ILO R164 recommendation of 1981 at an in-ternational level, and the directive 89/391 on safety and health at work of 1989 in the EU), which supports the inclusion of this discussion on OHS standards within the realm of HFE standards, given the intersecting interests of the two disciplines. Regarding economic considerations, some HFE interventions have been the object of cost-benefit analyses reported in the literature. In what concerns OHS, the literature has focused on the cost of occupational accidents, injuries, illnesses, and fatalities. Estimates of costs and benefits of complying with (or adopting) OHS standards are also available in the form of literature dealing with the mandatory U.S. OSHA standards.

Tidskriftsartikel (refereegranskat)abstract
- Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It is an ecologically and economically important group formed of mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas and shrubs, and which has a global distribution, occurring on every continent except Antarctica. Following the recent re-circumscription of 15 Caesalpinioideae genera as presented in Advances in Legume Systematics 14, Part 1, and using as a basis a phylogenomic analysis of 997 nuclear gene sequences for 420 species and all but five of the genera currently recognised in the subfamily, we present a new higher-level classification for the subfamily. The new classification of Caesalpinioideae comprises eleven tribes, all of which are either new, reinstated or re-circumscribed at this rank: Caesalpinieae Rchb. (27 genera / ca. 223 species), Campsiandreae LPWG (2 / 5-22), Cassieae Bronn (7 / 695), Cera-tonieae Rchb. (4 / 6), Dimorphandreae Benth. (4 / 35), Erythrophleeae LPWG (2 /13), Gleditsieae Nakai (3 / 20), Mimoseae Bronn (100 / ca. 3510), Pterogyneae LPWG (1 / 1), Schizolobieae Nakai (8 / 42-43), Sclerolobieae Benth. & Hook. f. (5 / ca. 113). Although many of these lineages have been recognised and named in the past, either as tribes or informal generic groups, their circumscriptions have varied widely and changed over the past decades, such that all the tribes described here differ in generic membership from those previously recognised. Importantly, the approximately 3500 species and 100 genera of the former subfamily Mimosoideae are now placed in the reinstated, but newly circumscribed, tribe Mimoseae. Because of the large size and ecological importance of the tribe, we also provide a clade-based classification system for Mimoseae that includes 17 named lower-level clades. Fourteen of the 100 Mimoseae genera remain unplaced in these lower-level clades: eight are resolved in two grades and six are phylogenetically isolated monogeneric lineages. In addition to the new classification, we provide a key to genera, morphological descriptions and notes for all 163 genera, all tribes, and all named clades. The diversity of growth forms, foliage, flowers and fruits are illustrated for all genera, and for each genus we also provide a distribution map, based on quality-controlled herbarium specimen localities. A glossary for specialised terms used in legume morphology is provided. This new phylogenetically based classification of Caesalpinioideae provides a solid system for communication and a framework for downstream analyses of biogeography, trait evolution and diversification, as well as for taxonomic revision of still understudied genera.
