In the present study, 16 samples representing Fasciola (Platyhelminthes: Trematoda: Digenea) from sheep and cattle from seven geographical locations in Niger were characterized genetically by sequences of the first (ITS-1) and second (ITS-2) internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA). The ITS rDNA was amplified from individual liver flukes by polymerase chain reaction (PCR), and the amplicons were sequenced directly. The lengths of the ITS-1 and ITS-2 sequences were 422 and 361/362 bp, respectively, for all liver fluke samples sequenced. Comparison of the ITS sequences of the Niger Fasciola samples examined in the present study with that of Fasciola hepatica, Fasciola gigantica, and the "intermediate Fasciola" from elsewhere revealed that the Niger Fasciola samples examined represent two species, namely F. hepatica and F. gigantica. This is the first demonstration of the existence of both F. hepatica and F. gigantica in Niger by a genetic approach, which provides foundation for further studies on F. hepatica and F. gigantica in Niger and has implications for studying the population genetic structure of the Niger Fasciola and for the diagnosis and control of the disease they cause.
Building on the capabilities' hierarchy concept, a model of the effect of organizational learning on hotel performance is proposed and tested in this study. Data was collected from 240 managers in the hotel industry of United Kingdom and Pakistan via survey. The results revealed strong direct inter-relation between different level of capabilities and an indirect relation between organizational learning and performance through these capabilities. This paper makes theoretical contributions to both management and hospitality and tourism research by generating an integrative and unifying framework for an organizational learning performance relationship, clarifying capabilities inter-relationships and empirically revealing the exact way these capabilities enhance performance. Also, it has practical implications for hotel managers' understanding on the development and use of capabilities as a hierarchy in enhancing their hotel performance.
PurposeThis study aims to offer and validate an integrated marketing capability-product innovations framework. Particularly, it aims to examine the role of adaptive marketing capability in enabling market ambidexterity and incremental as well as radical product innovation. Also it intends to investigate the moderating role of transformational leadership between adaptive marketing capability and market ambidexterity.Design/methodology/approachManufacturing firms in Pakistan, an emerging economy, are taken as the context for this study. A designed survey questionnaire is used for data collection. Partial least square technique is employed to empirically validate and test the hypothesized model with a sample of 192 manufacturing firms. Particularly, the two-stage approach in SmartPLS is used to validate measurement models, and structural equation modeling technique is used to test the proposed hypothesis.FindingsThe findings not only confirm that adaptive marketing capability is instrumental to both incremental and radical product innovations but also reveal that adaptive marketing capability serves an important antecedent to market ambidexterity shedding new lights on its mediating role in the relationship of adaptive marketing capability with incremental and radical product innovations. Moreover, the results find that the effectiveness of adaptive marketing capability to support market ambidexterity may involve a possible trade-off between exploitation and exploration when the leaders exhibit a low or high level of transformational leadership behavior.Originality/valueThis study contributes to outside-in strategic perspective and contextual ambidexterity literature by revealing the role of adaptive marketing capability as an important enabler of market ambidexterity which, in turn, allows the firm to simultaneously introduce incremental and radical product innovations. In this way, this study advances the current understanding of the antecedents and consequences of contextual ambidexterity. Also, this study provides insight into the types of capabilities needed for the firm's contextual and employees' behavioral adaptation to simultaneously manage exploitation and exploration within the same business unit which was lacking in the previous literature. Further, this study also offers a novel understanding of the conditional role of transformational leadership between adaptive marketing capability and market ambidexterity.
While researchers have conceptualized both dynamic and substantive capabilities in a variety of ways, there are still no established measures for either dynamic or substantive capabilities. Although learning has been referred to as a specific type of process underlying the evolution and development of dynamic capabilities, the deep connection between dynamic capabilities and organizational process research has not yet been adequately explored. There is a need for conceptualization and operationalization of these different aspects of the learning process. In this paper, we address these gaps in the literature by drawing upon concepts from the organizational learning, marketing and strategic management fields to understand better and define dynamic and substantive capabilities concepts. First, we define dynamic and substantive capabilities and form a theoretical foundation for their conceptualization. We then develop and test specific item measures for each construct. Our findings support our conceptualization and measurement of both these important aspects of organizational performance
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
