A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part to the large uncertainties of bottom depth retrievals caused by changes on bottom reflectivity. Here, we present a method based on mini unmanned aerial vehicles (UAS) images for discriminating bottom-reflected and water radiance components by taking advantage of shadows created by different
structures sitting on the bottom boundary. Aerial surveys were done with a drone Draganfly X4P during October 1 2013 in optically shallow waters of the Saint Lawrence Estuary, and during low tide. Colour images with a spatial resolution
of 3 mm were obtained with an Olympus EPM-1 camera at 10 m height. Preliminary results showed an increase of the relative difference between bright and dark pixels (dP) toward the red wavelengths of the camera's receiver. This is
suggesting that dP values can be potentially used as a quantitative proxy of bottom reflectivity after removing artefacts related to Fresnel reflection and bottom adjacency effects.Peer ReviewedPostprint (published version
Contemporary Micro-IT Capabilities and Organizational Performance: The Role of Online Customer Engagement
We theorize that the development of two contemporary social commerce-IT capabilities (social media and e-business technology) help to online engage customers to improve organizational performance. We test this theory by employing a secondary dataset on a sample of 100 small U.S. firms. The empirical analysis suggests that social media capability and e-business technology capability positively affect organizational performance through social and conventional online customer engagement. Research and managerial implications are discussed
Impact of Social Media on the Firmâs Knowledge Exploration and Knowledge Exploitation: The Role of Business Analytics Talent
Social media is one of the most disruptive technologies in executing a firmâs digital business transformation strategies. Does the firmâs ability to use social media affect its proficiency in exploring and exploiting knowledge? What should be the role of business analytics talent in this equation? We study theoretically and empirically these cutting-edge research questions. Our proposed research model argues that social media capability enables the development of knowledge exploration and knowledge exploitation, and business analytics talent exerts a positive reinforcing role in the impact of social media on knowledge exploration. We empirically tested the proposed research model with a secondary dataset from a sample of US firms using PLS path modeling. After running a robustness test by estimating eight alternatives/competing models, the empirical analysis revealed that social media capability is positively related to knowledge exploration and knowledge exploitation, but with a stronger effect on knowledge exploration. Moreover, business analytics talent plays a positive moderator role in the relationship between social media capability and knowledge exploration. This study contributes to the IS research by (1) introducing, developing, and operationalizing the concepts of social media capability and business analytics talent; and (2) theoretically arguing and empirically showing the pivotal role of social media capability in exploring new knowledge and the complementary role of business analytics talent. Our study also provides several critical lessons learned for top executives and proposes promising future IS research avenues.European Regional Development Fund (European Union)Spanish Government ECO201784138-P

Transactive Memory System and QM: Exploring Knowledge capacities
Purpose
â The purpose of this paper is to study how transactive memory systems (TMS) facilitate the transfer and absorption of knowledge in the presence of quality management (QM) within a university research and development (R&D) environment.
Design/methodology/approach
â The data come from a simple random sampling of 257 Spanish university R&D groups in nine different areas of knowledge. To verify the hypotheses, the authors used multiple linear regression analysis with a moderating effect.
Findings
â The conclusions show that the relationship between knowledge transfer (KT) and TMS is significant when QM practices are included as a moderating variable but that this is not the case for knowledge absorption (KA), which does not show any effect.
Research limitations/implications
â The effects described were found in a sample composed of various R&D sectors taken from a single country and not distributed equally. Further, the perception analyzed represents the judgment of a single manager.
Practical implications
â It is interesting to study this interaction in university R&D because of the important role R&D plays in the development of regions. Improving the internal processes of this research helps to make its results more competitive. This study contributes information on nonâbusiness management and introduces university R&D to the use of QM practices.
Originality/value
â The authors found no studies that test empirically the moderating effect of QM practices on the relationships studied in university R&D. The paper's results contribute information to help fill this gap and demonstrate once again that QM practices can be applied to any environment
The relationship between IT infrastructure leveraging, talent management and operational sustainability, and their effects on the business value of the operations strategy
The purpose of this research is to examine the role of information technology (IT) in the adoption of human resources (HR) and environmental management activities, a research topic that has not received much attention in prior literature. Drawing on the theory of operational and dynamic capabilities, we propose a model in which IT infrastructure leveraging enables the firm to create value from its operations management both directly and indirectly through talent management and operational sustainability. We test the model using the structural equation modeling (SEM) technique with an innovative secondary data set collected for a sample of 63 large firms. The empirical analysis suggests that IT infrastructure leveraging enables the firmâs proficiency to manage talent, which in turn facilitates execution of a more sustainable operations strategy to increase firm performance. The analysis also shows that IT infrastructure leveraging impacts firm performance directly in the long-term
Network Ties and Transactive Memory Systems: Leadership as an Enabler
Purpose
The purpose of this paper is to study the relationship between network ties (NT) and transactive memory systems (TMS), observed through three dimensions â specialization (TMSS), credibility (TMSCR), and coordination (TMSCO) â in the presence of leadership (LDR) as a moderating variable, in university research-and-development (R&D) groups.
Design/methodology/approach
The data are composed of 257 university R&D groups. To confirm the hypotheses, the authors use multiple linear regression analysis with a moderating effect.
Findings
The conclusions show that the relationships between NT and two of the three dimensions of TMS (TMSCR and TMSCO) are significant when LDR is included as a moderating variable. Although the effect of TMSS is positive, it is not significant. Including the interaction element enables better explanation of two of the dimensions of TMS in the sector analyzed. Thus, LDR is perfectly applicable to the university R&D environment.
Research limitations/implications
This research has several limitations that suggest further possibilities for empirical research. The limitations include the cross-sectional nature of the research and the judgment of a single manager as the basis of the perception analyzed for each group.
Practical implications
The authors provide several implications for R&D practitioners. The results of this study could be validated in other universities in other geographic areas, enabling better generalization and applicability of the results. The results described may serve as a guide for group leaders of university R&D. This research helps us to see the importance of LDR in forming internal research networks that help researchers to perform common projects in order to obtain better results in the group. Thus, the groups provided better results to society.
Originality/value
No studies have tested the moderating effect of LDR in university R&D empirically. The results provide information to fill this gap and demonstrate the applicability of LDR as a key element in the organization, improvement, and cohesion of R&D groups
Drivers for performance in innovative research groups: The mediating role of transactive memory system
This article contributes to research on transactive memory systems (TMSs) by analyzing the relationship between trust, collective mind (CM), and network ties (NT) as antecedents of performance in innovative university research (IUR), and the mediating role of the TMS in these relationships. The conceptual model grounded in seven hypotheses is tested through structural equations modeling. The data analyzed are drawn from 257 directors Spanish university research groups. The results show that TRUST, CM, and NT are positively related to the TMS and that the TMS is positively related to IUR. The most striking result is that the TMS mediates the relationships of TRUST, CM, and NT to IUR, becoming a necessary condition for TRUST, CM, and NT to improve IUR. These results support the conclusion that managers of university research groups should promote the development of TMSs to stimulate IUR in order to make these groups more competitive
Quality Management and collective mind: investigating university R&D from a group focus
This article analyses how Quality Management (QM) practices moderate the relationship between collective mind (CM), and knowledge transfer (KT) and absorption in university research and development (R&D) groups. The data are taken from 257 R&D groups in different Spanish universities. The findings show that the relationship between CM and KT is significant when QM is included as a moderating variable because QM permits better communication and fosters stronger ties between group members. In the case of knowledge absorption (KA), however, QM does not have a significant effect. The final section presents the study's conclusions and implications. As no studies have tested these effects empirically, our conclusions are highly relevant for academics and researchers
Dynamic capabilities, human resources and operating routines: a new product development approach
Purpose
â The purpose of this paper is to explain the outcomes and role of dynamic capabilities (DCs). To explain the outcomes, the authors study the relationship between new product development (NPD) (an example of DCs) and metaflexibility. To explain the role of DCs, the authors study how human resources and operating routines moderate the role of DCs in achieving adaptation in the firm.
Design/methodology/approach
â Using data from 200 managers of Spanish firms, the authors apply regression analysis to test the moderating role of human resources and operating routines in the relationship between NPD and metaflexibility.
Findings
â The results demonstrate that highly qualified and committed workers enhance the effectiveness of NPD, while high frequency in repetition of operating routines significantly damages such effectiveness.
Research limitations/implications
â This study is limited to analysing a unique DC (NPD), but future research could explore contributions on other consolidated DCs (e.g. alliance management capability) and compare results. Also, the database on managerial perceptions rather than objective measures.
Practical implications
â Managers who must address environmental changes should connect generation of DCs to complementary functional strategies, especially human resources strategy.
Originality/value
â This paper suggests additional outcomes derived from DCs, such as metaflexibility. It attempts to understand the complex process by which DCs interact to modify operating routines in order to respond to environmental changes
Examining desorptive capacity in supply chains: the role of organizational ambidexterity
Abstract
Purpose â The purpose of this paper is to explain how a buying organizationâs desorptive capacity relative
to its supply network enhances the organizationâs supply chain competence. The research also analyzes the
contingent role of the balanced and combined dimensions of ambidexterity in this relationship.
Design/methodology/approach â Empirical results are obtained through analysis of survey data from a
sample of 270 European firms. Hierarchical regression analysis is used to test the hypotheses.
Findings â The results confirm, first, the positive and significant relationship between the buying
organizationâs desorptive capacity and supply chain competence; and, second, the key moderating role of
organizational ambidexterity, especially in its combined dimension, in this relationship.
Practical implications â The study suggests that desorptive capacity is key to the organizationâs
contribution to supply chain competitiveness. The authors also provide practitioners with better
understanding of the extent to which they should attempt to balance exploration and exploitation or/and to
maximize both simultaneously when seeking greater benefit from desorptive capacity.
Originality/value â This study extends desorptive capacity research to supply chain management.
It responds to calls in the desorptive capacity literature for deeper understanding of the benefits of desorptive
capacity and of the role organizational ambidexterity plays in the success of desorptive capacity.
By analyzing the independent effects of the combined and balanced dimensions of ambidexterity, the authors
advance conceptual and operational understanding of the role of ambidexterity needed in the literatur
