This paper proposes a research model that outlines the determinants of functional families and profitable businesses–requisites for family business sustainability. Two features distinguish the model from previous models: inclusion of the family in the same detail as the business and emphasis on the key features of family and business. Delineation of the interface between the family and the business permits the use of research methods that allow for variable degrees of overlap of family and business rather than assuming that family businesses constitute either a single system or two separate systems. The research model is also compatible with a variety of theoretical perspectives.

Family businesses are vital but understudied economic and social units. Previous family business research is limited relative to its definitions, sampling, and resulting empirical evidence. This paper presents an alternative methodological approach to the study of family businesses with the potential for allowing multiperspective and detailed analyses of the nature and internal dynamics of both the family and the business and the interaction between the two.

All dogs treated by MIPO healed rapidly without any complications, nevertheless the difference in radiographic healing between the two groups was not significant.

For dogs with radius-ulna fractures, data indicated that bridging osteosynthesis combined with a minimally invasive approach contributed to rapid healing after MIPO. The MIPO technique may offer some clinical advantage over ORIF, given that complete radius-ulna fracture healing was achieved in a shorter time with MIPO.

The objectives of this study were (1) to measure normal thickness values of the muscularis, submucosal, mucosal and serosal layers in each gastrointestinal (GI) segment (gastric fundus, body and pyloric antrum; duodenum; jejunum; ileum; colon), and (2) to calculate a ratio of muscularis and mucosal layer thickness to aortic diameter measured at the level of the celiac artery (Musc:Ao and Muc:Ao) in each GI segment in a sample of healthy cats. Ultrasonographic examination of the GI tract was performed, and measurements of the individual layers in each GI segment were obtained in 38 healthy cats without clinical evidence of disease. The muscularis layer was significantly thickest in the ileum, compared with other segments, and it was thicker than the submucosa in all segments except the colon. The mucosa was the thickest layer in all segments, and was thickest in the duodenum and ileum. Measurements of the submucosal and serosal layers were not significantly different between all segments. Musc:Ao and Muc:Ao in each segment were 0.12 and 0.25 (gastric fundus), 0.12 and 0.18 (gastric body), 0.11 and 0.16 (pyloric antrum), 0.08 and 0.27 (duodenum), 0.08 and 0.22 (jejunum), 0.14 and 0.25 (ileum), and 0.05 and 0.08 (colon), respectively. Musc:Ao and Muc:Ao are clinically relevant values that can be used to objectively identify thickening of the muscularis and mucosal layers in response to GI diseases.
