Motivation,opportunity, and ability in knowledge transfer: a social network approach

Although previous research indicates a variety of facilitators of knowledge transfer, many firms still suffer from knowledge transfer difficulties. This study explores the relational antecedents of knowledge transfer by integrating the motivation–opportunity–ability framework with a social network approach, which emphasizes the relations among people rather than their attributes. To rigorously validate causal relations among network variables, the social networks of employees in a research and development department were surveyed twice in 6 months. A regression analysis with 76 × 76 networks using a multiple regression quadratic assignment procedure showed that opportunity and motivation were the first- and second-most influential factors for knowledge transfer, respectively. There was a marginal, but statistically significant effect for ability. The creation of a working environment in which knowledge transfer can easily take place, and motivating competent employees to transfer their knowledge, are critical to successful knowledge transfer.     

Is social networking a waste of time? The impact of social network and knowledge characteristics on job performance

People use social media to help them solve problems and enhance performance. Users may engage in diverse social interactions online, increasing their knowledge base through both weak and strong ties. In this study we investigate the impact of social networks on job performance, focusing on knowledge quality and diversity based on social network theory and the knowledge-based view. The empirical analysis reveals that the strength of social network ties is strongly associated with knowledge quality in offline interactions, while social network diversity is associated with knowledge quality in online interactions. Knowledge quality acquired from social network has a significant impact on both creativity and productivity of job performance in the workplace. However, knowledge diversity acquired from diverse social network interactions is strongly associated with creativity, but not with productivity. The results of this study increase our understanding of the knowledge sourcing behaviors of workers.     

Managing supply chain knowledge-based linkages for improving operational performance

Purpose – This paper aims to explore the role of internal and external knowledge-based linkages across the supply chain in achieving better operational performance. It investigates how knowledge is accumulated, shared, and applied to create organization-specific knowledge resources that increase and sustain the organization’s competitive advantage. Design/methodology/approach – This paper uses a single case study with multiple, embedded units of analysis, and the social network analysis (SNA) to demonstrate the impact of internal and external knowledge-based linkages across multiple tiers in the supply chain on the organizational operational performance. The focal company of the case study is an Italian manufacturer supplying rubber components to European automotive enterprises. Findings – With the aid of the SNA, the internal knowledge-based linkages can be mapped and visualized. We found that the most central nodes having the most connections with other nodes in the linkages are the most crucial members in terms of knowledge exploration and exploitation within the organization. We also revealed that the effective management of external knowledge-based linkages, such as buyer company, competitors, university, suppliers, and subcontractors, can help improve the operational performance. Research limitations/implications – First, our hypothesis was tested on a single case. The analysis of multiple case studies using SNA would provide a deeper understanding of the relationship between the knowledge-based linkages at all levels of the supply chain and the integration of knowledge. Second, the static nature of knowledge flows was studied in this research. Future research could also consider ongoing monitoring of dynamic linkages and the dynamic characteristic of knowledge flows. Originality/value – To the best of our knowledge, the phrase ‘knowledge-based linkages’ has not been used in the literature and there is lack of investigation on the relationship between the management of internal and external knowledge-based linkages and the operational performance. To bridge the knowledge gap, this paper will show the importance of understanding the composition and characteristics of knowledge-based linkages and their knowledge nodes. In addition, this paper will show that effective management of knowledge-based linkages leads to the creation of new knowledge and improves organizations’ operational performance.     

Detection of acute kidney injury in premature asphyxiated neonates by serum neutrophil gelatinase-associated lipocalin (sNGAL) – sensitivity and specificity of a potential new biomarker

Introduction

Acute kidney injury (AKI) is common in neonatal intensive care units (NICU). In recent years, every effort is made for early detection of AKI. Our hypothesis was that serum neutrophil gelatinase-associated lipocalin (sNGAL) may be a reliable screening test for early diagnosis of AKI in premature neonates after perinatal asphyxia. Therefore, our aim was to assess the diagnostic accuracy of sNGAL for AKI in premature asphyxiated neonates.

Materials and methods

AKI was defined in the third day of life (DOL 3) as a serum creatinine (sCr) increase ≥ 26.5 μmol/L from baseline (the lowest previous sCr). According to the increase of sCr, AKI patients were divided in AKIN1 (sCr increase up to 1.9 baseline) and AKIN2 (sCr increase from 2.0 to 2.9 baseline). sNGAL levels were measured on DOL 1, 3 and 7.

Results

AKI was diagnosed in 73 (0.676) of 108 enrolled premature asphyxiated neonates. Sixty one patients (0.836) were classified in AKIN1 and 12 patients (0.164) in AKIN2. sNGAL reached the maximal concentrations on DOL 1 within 4 hours after admission to NICU, being higher in AKI compared with no-AKI group (160.8 ± 113.1 vs. 87.1 ± 81.6; P < 0.001) as well as in AKIN2 compared with AKIN1 group (222.8 ± 112.9 vs. 147.8 ± 109.9; P < 0.001). The best areas under the receiver operating characteristic curves (AUC) for prediction of AKI were 0.72 [95% (0.62-0.80) P < 0.001] on DOL1 at 2h and 0.72 [95% (0.63-0.80) P < 0.001] at 4th hour after admission respectively. The corresponding sNGAL cutoff concentrations were 84.87 ng/mL (sensitivity 69.0% and specificity 71.9%) and 89.43 ng/mL (sensitivity 65.7% and specificity 74.3%).

Conclusions

In premature asphyxiated neonates sNGAL measured within the first 4 hours of DOL 1 is predictive of the occurrence and severity of AKI. Therefore, plasma levels of NGAL may be used for early diagnosis of AKI in these patients.Key words: serum neutrophil gelatinase-associated lipocalin, acute kidney injury, premature neonates, biomarker     

Reinventing the public sector in Africa through knowledge management

There is extensive coverage in literature of knowledge management (KM) implementation based on private sector entities. Although recent trends have been characterised by a shift towards understanding KM in the public sector organisations, there is very little focus on the public sector entities in Africa. KM has become popular in modern organisations because it is capable of enhancing the effectiveness and efficiency of entities if properly implemented. While the explosion of the internet has seen the emergence of public sector transformation programmes such as e-government plans, most African states have wholly adopted these without due consideration to the structural constraints they would face in their implementation. Having observed that e-government is technology-based and most African states lack the necessary information technology (IT) tools to effectively implement it, my proposition in this paper is that the most viable option of transforming the public sector in Africa could be through KM, rather than e-government. Nevertheless, e-government plans in African states should be implemented as a component of the overall KM strategy.     

Content and knowledge provision service – a way to build intellectual capital in learning organizations

This paper presents the concept and the implementation of the Content and/or Knowledge Provision (CKP) service. The service is developed as a part of research within Intelligent Learning Extended Organization, an 7th Framework Program for R&D project in the area of technology-enhanced learning. The project aimed at enhancing cross-organizational Learning and Knowledge Building (LKB) practices at workplaces, leading to continuous growth of organization’s intellectual capital. By using the CKP service, employees can upload different kinds of knowledge assets into a knowledge repository, annotate them and (re-)discover relevant ones by performing semantic search over the knowledge repository. Hence, the service effectively serves as a content and knowledge-sharing facility and semantic search engine within a learning organization. Furthermore, CKP enables collaborative manipulation and annotation of knowledge assets in the repository, thus supporting all three components of intellectual capital.     

Optimizing knowledge transfer by new employees in companies

Companies realize innovations by creating and implementing new knowledge. One possible source of innovative ideas are new employees. Based on an existing game-theoretic model the conditions of efficient knowledge transfer in a team are analyzed. Offering knowledge to a colleague cannot be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives, which motivate the employees to act in favor of the company. The aim of this paper is to show what influences the propensity of the employees to engage in knowledge transfer and how the management can design the incentive structure for optimal transfer. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is at least partly generalized on more players. The relevance of the adequate team size is shown: too few or too many developers decrease the remaining company profit. A further result is that depending on the cost structure, perfect knowledge transfer is not always best for the profit of the company.     

Linking social capital to organizational growth

In the current discussion of the intellectual capital, three main themes have been brought up: intangible assets, the dynamic capabilities to create and modify these assets, and the social relationships in which the knowledge processes take place, that is social capital. Within the latter view, knowledge is understood as a socially constructed and shared resource, and the focus is on the characteristics of the social relationships connecting the various actors and on the benefits these bring to the participants. Even though it is widely agreed that knowledge is essentially social by nature and that social capital does matter to the corporate bottom line, there are relatively few previous studies that have empirically examined the impact of social capital on organizational growth. To bridge this gap, the paper empirically examines how social capital residing in both intra-organizational and inter-organizational relationships of firms is related with organizational growth. The results suggest that contrary to the theoretical claims in the existing literature, social capital has only meagre role in promoting organizational growth.
