Combining Big Data and Artificial Intelligence for Managing Collective Knowledge in Unpredictable Environment—Insights from the Chinese Case in Facing COVID-19
No full textThe increasing fluidity of social and business configurations made possible by the opportunities provided by the World Wide Web and the new technologies is questioning the validity of consolidated business models and managerial approaches. New rules are emerging and multiple changes are required to both individuals and organizations engaged in dynamic and unpredictable paths. In such a scenario, the paper aims at describing the potential role of big data and artificial intelligence in the path toward a collective approach to knowledge management. Thanks to the interpretative lens provided by systems thinking, a framework able to explain human-machine interaction is depicted and its contribution to the definition of a collective approach to knowledge management in unpredictable environment is traced. Reflections herein are briefly discussed with reference to the Chinese governmental approach for managing COVID-19 spread to emphasise the support that a technology-based collective approach to knowledge management can provide to decision-making processes in unpredictable environments
An alternative way to predict knowledge hiding: The lens of transformational leadership
Full text linkThe present study explores one of the biggest causes of the lack of organizational knowledge creation: knowledge hiding (KH). KH can be provoked by the deviant and detached behaviours of leaders and/or the motivations of employees. In this context, leaders assume a key role in reducing the effect of KH. Through the lens of transformational leadership (TL), a sample of 758 European SMEs with a total number of 2,232 employees operating in a knowledge-intensive sector is investigated. The scope is to evaluate the correlation between the three main characteristics of transformational leadership (i.e., trust, a collaborative environment, and the involvement of employees) and the phenomenon of KH through a logistic regression analysis. It emerges that TL can influence the organizational context and redefine the behaviours related to KH. In addition, empathic leadership can provide added value for companies since a collaborative environment and common objectives reduce the level of KH
Building dynamic capabilities for international marketing knowledge management
No full textPurpose
By using the lens of knowledge-based view (KBV) and focusing on individual loci of knowledge, the present study addresses whether marketing knowledge management (MKM) is rooted in individual dynamic capabilities (DCs) and consequently whether it has a close relationship with the three main DCs, namely, the ability to solve a problem (substantive capability); the adaptation to rapid changes (adaptative capability); and the ability to change the way individuals solve problems (change capability).
Design/methodology/approach
The present study aimed to examine the effects of MKM (the quantitative variable) on DCs (the quantitative variables). Drawing on the relevant literatures, the researchers have developed a model that defines the subjects of the empirical test. To do this, the authors opted for a hypothetico-deductive approach, which is commonly used in quantitative studies. The empirical analysis involved a linear regression and a sample of 105 managers of Italian companies operating in the knowledge intensive sector.
Findings
Substantive, adaptive and change capabilities were all positively correlated with MKM. The results indicate the significant need for individual DCs to improve business performance in terms of creativity, innovation, and flexibility in response to market changes.
Originality/value
The authors show that individual MKM has a strong relationship with individual DCs when the employees have the capacity to solve problems, adapt, and change. In turn, managers are strategically creative and imagine future possibilities in the international marketing sphere. This includes procedures and routines to learn in local markets. The study also stresses the fact that individuals represent the primary loci of knowledge
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The Lq Control Problem For Markovian Jumps Linear Systems With Horizon Defined By Stopping Times
No full textThis paper deals with a stochastic optimal control problem involving discrete-time jump Markov linear systems. The jumps or changes between the system operation modes evolve according to an underlying Markov chain. In the model studied, the problem horizon is defined by a stopping time τ which represents either, the occurrence of a fix number N of failures or repairs (TN), or the occurrence of a crucial failure event (τΔ), after which the system is brought to a halt for maintenance. In addition, an intermediary mixed case for which T represents the minimum between TN and τΔ is also considered. These stopping times coincide with some of the jump times of the Markov state and the information available allows the reconfiguration of the control action at each jump time, in the form of a linear feedback gain. The solution for the linear quadratic problem with complete Markov state observation is presented. The solution is given in terms of recursions of a set of algebraic Riccati equations (ARE) or a coupled set of algebraic Riccati equation (CARE).1703707Krasovskii, N.N., Lidiskii, E.A., Analytical design of controllers in systems with random atributes I,II, III (1961) Automation Remote Contr., 22, pp. 1021-1025Blair, W.P., Sworder, D.D., Feedback control of a class of linear discrete systems with jump parameters and quadratic cost criteria (1975) International Journal of Control, 21 (5), pp. 833-841Ji, Y., Chizeck, H.J., Loparo, K.A., Stability and control of discrete-time jump linear systems (1991) Control Theory Advanced Technology, 7, pp. 247-270Ji, Y., Chizeck, H.J., Controllability, observability and discrete-time Markovian jump linear quadratic control (1989) International Journal of Control, 48, pp. 481-498Ji, Y., Chizeck, H.J., Jump linear quadratic Gaussian control: Steady-state solution and testable conditions (1990) Control Theory and Advanced Technology, 6 (3), pp. 289-319Chizeck, H.J., Willsky, A.S., Castano, D., Discrete-time Markovian jump linear quadratic optimal control (1986) International Journal of Control, 43, pp. 213-231Costa, O.L.V., Fragoso, M.D., Stability results for discrete-time linear systems with Markovian jumping parameters (1993) Journal of Mathematical Analysis and Applications, 179, pp. 154-178Costa, O.L.V., Fragoso, M.D., Discrete-time LQ-optimal control problems for infinite Markov jump parameters systems (1995) IEEE Trans.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
