THE EFFECTS OF ORGANIZATIONAL AMBIDEXTERITY AND CO-CREATION ON ORGANIZATION PERFORMANCE
Maria de Lurdes Sarmento,Cl?udia Sim?es 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07
The interest in the study of organizations’ ambidexterity (i.e., the capacity of combining organizational explorative and exploitative capabilities) entails expectations associated to its conceptual value and practical implications related to high-performing companies and long-term survival. In parallel, it is relevant to understand organizational ambidexterity under the marketing lenses, in particular, looking at the notion of co-creation and service-dominant logic. This study addresses the effects of organizational ambidexterity on organizational co-creation and evaluates whether these dynamics are different in SMEs and Large companies. We further assess how they contribute to the enhancement of firms’ performance. To the endeavor, we develop and empirically test a conceptual model.
Factor Analysis of Linear Type Traits and Their Relation with Longevity in Brazilian Holstein Cattle
Kern, Elisandra Lurdes,Cobuci, Jaime Araujo,Costa, Claudio Napolis,Pimentel, Concepta Margaret McManus Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.6
In this study we aimed to evaluate the reduction in dimensionality of 20 linear type traits and more final score in 14,943 Holstein cows in Brazil using factor analysis, and indicate their relationship with longevity and 305 d first lactation milk production. Low partial correlations (-0.19 to 0.38), the medium to high Kaiser sampling mean (0.79) and the significance of the Bartlett sphericity test (p<0.001), indicated correlations between type traits and the suitability of these data for a factor analysis, after the elimination of seven traits. Two factors had autovalues greater than one. The first included width and height of posterior udder, udder texture, udder cleft, loin strength, bone quality and final score. The second included stature, top line, chest width, body depth, fore udder attachment, angularity and final score. The linear regression of the factors on several measures of longevity and 305 d milk production showed that selection considering only the first factor should lead to improvements in longevity and 305 milk production.

The objective of this study was to estimate genetic and phenotypic parameters for linear type traits, as well as milk yield (MY), fat yield (FY) and protein yield (PY) in 18,831 Holstein cows reared in 495 herds in Brazil. Restricted maximum likelihood with a bivariate model was used for estimation genetic parameters, including fixed effects of herd-year of classification, period of classification, classifier and stage of lactation for linear type traits and herd-year of calving, season of calving and lactation order effects for production traits. The age of cow at calving was fitted as a covariate (with linear and quadratic terms), common to both models. Heritability estimates varied from 0.09 to 0.38 for linear type traits and from 0.17 to 0.24 for production traits, indicating sufficient genetic variability to achieve genetic gain through selection. In general, estimates of genetic correlations between type and production traits were low, except for udder texture and angularity that showed positive genetic correlations (>0.29) with MY, FY, and PY. Udder depth had the highest negative genetic correlation (–0.30) with production traits. Selection for final score, commonly used by farmers as a practical selection tool to improve type traits, does not lead to significant improvements in production traits, thus the use of selection indices that consider both sets of traits (production and type) seems to be the most adequate to carry out genetic selection of animals in the Brazilian herd.
Sand-Nonwoven geotextile interfaces shear strength by direct shear and simple shear tests
Vieira, Castorina Silva,Lopes, Maria de Lurdes,Caldeira, Laura Techno-Press 2015 Geomechanics & engineering Vol.9 No.5
Soil-reinforcement interaction mechanism is an important issue in the design of geosynthetic reinforced soil structures. This mechanism depends on the soil properties, reinforcement characteristics and interaction between these two elements (soil and reinforcement). In this work the shear strength of sand/geotextile interfaces were characterized through direct and simple shear tests. The direct shear tests were performed on a conventional direct shear device and on a large scale direct shear apparatus. Unreinforced sand and one layer reinforced sand specimens were characterized trough simple shear tests. The interfaces shear strength achieved with the large scale direct shear device were slightly larger than those obtained with the conventional direct shear apparatus. Notwithstanding the differences between the shear strength characterization through simple shear and direct shear tests, it was concluded that the shear strength of one layer reinforced sand is similar to the sand/geotextile interface direct shear strength.
