Home Made Cars: An insight on Consumer Ethnocentrism – Case Saab

Saab outstands in the history of the Finnish car manufacturing. This is not only due to that these cars have been manufactured in Finland more than other passenger vehicles altogether. Finns also have a special emotional attachment to the “Finnish Saabs”. Findings from previous studies show that consumers connect cars well to the origin of the brand (COB). They are however rarely aware of the Country of Manufacturing (COM). Domestic brands are often popular in the COB, but research from situations in which the domestic origin is limited to the COM is rare. The case of this study is a phenomenon, in which the products origin is two dimensional and divided into domestic COM and foreign COB. The aim is to understand the phenomenon’s effect on consumer behavior. The research problem is approached with two sub questions: • Which country do consumers perceive as the origin country of the car? • What is the role of this origin in the consumers’ product perception and purchasing decision of the car? The theoretical framework of this study applies previous findings of two areas of interest: Country of Origin effect and Consumer Ethnocentrism. This is followed by feasibility studies that present and discuss the history and current state of Finnish car manufacturing. Based on the findings of earlier stages of the study, the role of the domestic COM on consumer behavior is presumed high. This expectation is confirmed by the experts and also by the first consumer respondent, who states domestic origin having been the main motivation to his car choice. All further consumer respondents do however not connect Saab to the home country, but discuss it as a Nordic car. This unexpected finding means that they do not perceive the origin to be neither the COM nor COB, but a geographical area that includes both countries. In other words, consumers have widened their in-group in a way that is in this thesis explained with reference group theory. The consumers’ perceived origin of the car is in this research found to be an important factor to the consumers’ product perception and purchasing decision. Being fit for the yields of the local environment is discovered to have been the most important factor to Finnish consumers purchasing choice of a Saab and the Nordic origin has been an indicator of this fit to them.

Resultados tratamiento de las fracturas intertrocantéricas en el Hospital Universitario Mayor MEREDÍ

Las fracturas intertrocantericas son una importante causa de la morbimortalidad en los adultos mayores. Requieren la mayoria manejo quirurgico. No se ha logrado definir si es mejor el tratamiento con osteosintesis o artoplastia de cadera. Por esta razon decidimos realizar un estudio identificando los resultados en cada uno de los tratamientos con poblacion colombiana en el Hospital Universitario Mayor Mederi. Metodos: Estudio de serie de casos. Se analizó una cohorte retrospectiva de pacientes mayores de 59 años con fractura intertrocantérica en el Hospital Universitario Mayor Méderi. Resultados: Se reportaron un total de 179 pacientes con diagnóstico de fractura intertrocantérica. De los cuales se realizaron 100 osteosíntesis , 20 reemplazos totales de cadera y 59 hemiartroplastias. La mortalidad fueron 11 pacientes que corresponde al 6.1%, 3 fueron hombres y 8 mujeres, en cuanto al procedimiento realizado a 7 pacientes se les realizo osteosíntesis y a los 4 restantes se les realizo hemiartroplastia. En total 7 infecciones las cuales se presentaron respectivamente en 6 osteosíntesis y 1 hemiartroplastia. Discusión: La mortalidad fue mayor en la osteosíntesis con 7 pacientes que equivale al 63,6 % de la mortalidad total del estudio. Los porcentajes de infección postoperatoria fueron mayores en la osteosíntesis , encontrándose que del total de pacientes intervenidos 3,9% se infectaron y de estos el 85,7 % corresponden a osteosíntesis versus 14,3% de hemiartroplastia. El sangrado postoperatorio fue mayor a 500 cc en un 39% de las osteosíntesis y en un 44% en las hemiartroplastias. Conclusión: el tratamiento de las fracturas intertrocantéricas tuvo menor mortalidad y menor porcentaje de infección cuando los pacientes fueron tratados con hemiartroplastia y reemplazo total de cadera.

Ephrin-B2 controls VEGF-induced angiogenesis and lymphangiogenesis

In development, tissue regeneration or certain diseases, angiogenic growth leads to the expansion of blood vessels and the lymphatic vasculature. This involves endothelial cell proliferation as well as angiogenic sprouting, in which a subset of cells, termed tip cells, acquires motile, invasive behaviour and extends filopodial protrusions. Although it is already appreciated that angiogenesis is triggered by tissue-derived signals, such as vascular endothelial growth factor (VEGF) family growth factors, the resulting signalling processes in endothelial cells are only partly understood. Here we show with genetic experiments in mouse and zebrafish that ephrin-B2, a transmembrane ligand for Eph receptor tyrosine kinases, promotes sprouting behaviour and motility in the angiogenic endothelium. We link this pro-angiogenic function to a crucial role of ephrin-B2 in the VEGF signalling pathway, which we have studied in detail for VEGFR3, the receptor for VEGF-C. In the absence of ephrin-B2, the internalization of VEGFR3 in cultured cells and mutant mice is defective, which compromises downstream signal transduction by the small GTPase Rac1, Akt and the mitogen-activated protein kinase Erk. Our results show that full VEGFR3 signalling is coupled to receptor internalization. Ephrin-B2 is a key regulator of this process and thereby controls angiogenic and lymphangiogenic growth.

PDZ interaction site in ephrinB2 is required for the remodeling of lymphatic vasculature

The transmembrane ligand ephrinB2 and its cognate Eph receptor tyrosine kinases are important regulators of embryonic blood vascular morphogenesis. However, the molecular mechanisms required for ephrinB2 transduced cellular signaling in vivo have not been characterized. To address this question, we generated two sets of knock-in mice: ephrinB2DeltaV mice expressed ephrinB2 lacking the C-terminal PDZ interaction site, and ephrinB2(5F) mice expressed ephrinB2 in which the five conserved tyrosine residues were replaced by phenylalanine to disrupt phosphotyrosine-dependent signaling events. Our analysis revealed that the homozygous mutant mice survived the requirement of ephrinB2 in embryonic blood vascular remodeling. However, ephrinB2DeltaV/DeltaV mice exhibited major lymphatic defects, including a failure to remodel their primary lymphatic capillary plexus into a hierarchical vessel network, hyperplasia, and lack of luminal valve formation. Unexpectedly, ephrinB2(5F/5F) mice displayed only a mild lymphatic phenotype. Our studies define ephrinB2 as an essential regulator of lymphatic development and indicate that interactions with PDZ domain effectors are required to mediate its functions.

FOXC2 and fluid shear stress stabilize postnatal lymphatic vasculature

Biomechanical forces, such as fluid shear stress, govern multiple aspects of endothelial cell biology. In blood vessels, disturbed flow is associated with vascular diseases, such as atherosclerosis, and promotes endothelial cell proliferation and apoptosis. Here, we identified an important role for disturbed flow in lymphatic vessels, in which it cooperates with the transcription factor FOXC2 to ensure lifelong stability of the lymphatic vasculature. In cultured lymphatic endothelial cells, FOXC2 inactivation conferred abnormal shear stress sensing, promoting junction disassembly and entry into the cell cycle. Loss of FOXC2-dependent quiescence was mediated by the Hippo pathway transcriptional coactivator TAZ and, ultimately, led to cell death. In murine models, inducible deletion of Foxc2 within the lymphatic vasculature led to cell-cell junction defects, regression of valves, and focal vascular lumen collapse, which triggered generalized lymphatic vascular dysfunction and lethality. Together, our work describes a fundamental mechanism by which FOXC2 and oscillatory shear stress maintain lymphatic endothelial cell quiescence through intercellular junction and cytoskeleton stabilization and provides an essential link between biomechanical forces and endothelial cell identity that is necessary for postnatal vessel homeostasis. As FOXC2 is mutated in lymphedema-distichiasis syndrome, our data also underscore the role of impaired mechanotransduction in the pathology of this hereditary human disease.
