Contextualizing AMO Explanations of Knowledge Sharing in MNEs: The Role of Organizational and National Culture

Ability, motivation, and opportunity (AMO) approaches have dominated studies of knowledge sharing in multinational enterprises (MNEs). We argue that there is a need to consider both the national and organizational cultural contexts. Beyond their direct influence on knowledge sharing with colleagues in other business units (BUs), national and organizational culture significantly reinforce the positive relation between individual motivation and knowledge sharing. Thus, our multi-level approach to knowledge sharing in MNEs gives rise to a contextualized AMO approach that provides a novel and more potent understanding of variations in knowledge sharing. At the individual level, our approach includes the degree of ability in the sense of professional competence, intrinsic motivation, and opportunities to interact with colleagues in other BUs. At the organizational and country levels, we examine the direct and indirect effects of a collaborative culture on knowledge sharing. We employ data from an MNE that operates across a variety of regions, including the Nordic countries, Central and Eastern Europe, and Southeast Asia. The sample consists of 11,484 individuals nested in 1235 departments in 11 countries. As well as confirming the significance of individual competence, intrinsic motivation, and opportunities for interaction for knowledge sharing, our findings reveal that both organizational culture and national culture are important factors for our understanding of knowledge sharing. This suggests that over and above recruiting intrinsically motivated employees, managers can enhance knowledge sharing by developing collaborative organizational cultures at the departmental level.

Teams and Project Performance: An Ability, Motivation, and Opportunity Approach

This article analyzes the relationships between project performance and the team’s ability, motivation, and opportunity (AMO). We contribute to the project management literature by exploring which combinations of AMO factors are best for project performance at different levels of complexity. We test our hypotheses on a sample of 285 projects. Our study shows that in simple projects, ability is the key factor both as a main effect and as a constraining factor that acts as a bottleneck for project performance. In the case of complex projects, the multiplicative model is superior given the significant interaction effects of motivation.

The dual influences of proximity on knowledge sharing

Purpose

The authors focus on how intra-organizational proximity influences the frequency of knowledge transfer in dyads, and the authors seek to balance the over-socialized and under-socialized perspectives of knowledge sharing by focusing on how proximity both indirectly (mediated by social relationships) and directly influences the frequency of knowledge sharing. Empirically, the authors analyze how proximity in a five-story building directly and indirectly influences the frequency of knowledge sharing.

Design/methodology/approach

As the authors were interested in exploring the frequency of knowledge sharing among individuals in knowledge sharing dyads, they used a survey to approach individuals directly and obtain information on the frequency of their knowledge sharing. The authors have complete data on 796 dyads on which they tested their hypotheses. Further, the physical distance in a dyad was measured as the walking distance (measured in meters) between individuals.

Findings

The authors first find that proximity positively affects the frequency of knowledge sharing indirectly through its promotion of social relationships. Second, it is noticeable that the direct relationship between proximity and knowledge sharing is stronger than the indirect via the promotion of social relationships. In sum, the authors’ results contribute to the knowledge sharing literature by emphasizing and clarifying how proximity both directly and indirectly influences knowledge sharing.

Research limitations/implications

This study has some limitations. First, this study only measured the frequency of knowledge sharing among individuals. Neither individual nor organizational outcomes of knowledge sharing were considered. Second, the authors did not distinguish between different channels for knowledge sharing, such as face-to-face or face-to-interface.

Practical implications

One practical implication is that knowledge sharing spanning, for instance, 50 m compared to knowledge sharing spanning 30 m may not necessarily require more resources, as the negative effect of 30 and 50 m distances is almost similar, as the negative effect of distance starts to fade out at 30 m. Another practical implication for the direct effect of proximity on knowledge sharing is that to foster knowledge sharing organizational practices need to create opportunities for employees to span both horizontal and vertical distances.

Originality/value

The authors’ results contribute to the knowledge sharing literature by empirically emphasizing and clarifying how intra-organizational proximity both directly and indirectly influences knowledge sharing.

Effect on non-vascular outcomes of lowering LDL cholesterol in patients with chronic kidney disease: results from the Study of Heart and Renal Protection

Background

Reducing LDL cholesterol (LDL-C) with statin-based therapy reduces the risk of major atherosclerotic events among patients with chronic kidney disease (CKD), with no evidence of an excess risk of cancer or death from any non-vascular cause. However, non-randomized data have suggested that statin therapy may have effects (both adverse and beneficial) on particular non-vascular conditions that do not cause death.

Methods

The Study of Heart and Renal Protection (SHARP) randomized patients with CKD to simvastatin 20 mg plus ezetimibe 10 mg (simvastatin/ezetimibe) daily versus matching placebo. Participants were followed up at least 6 monthly and all post-randomization serious adverse events (SAEs) were recorded. This supplementary analysis reports the effects of treatment on non-vascular SAEs, overall, by system of disease, by baseline characteristics, and by duration of follow-up.

Results

During a median of 4.9 years follow-up, similar numbers of participants in the two groups experienced at least one non-vascular SAE (3551 [76.4%] simvastatin/ezetimibe vs 3537 [76.6%] placebo; risk ratio [RR] 0.99, 95% confidence interval [CI] 0.95–1.04). There was no good evidence of any significant effect of simvastatin/ezetimibe on SAEs attributed to any particular nonvascular disease system (of 43 comparisons, only 3 yielded an uncorrected p value < 0.05, of which the smallest was p = 0.02). The relative risk of any nonvascular SAE did not vary significantly among particular prognostic subgroups or by duration of follow-up.

Conclusions

In the SHARP trial, allocation to simvastatin/ezetimibe combination therapy was not associated with any significant non-vascular hazard.

Trials registration

SHARP was retrospectively registered after the first participant was enrolled in 2003 at ISRCTN (ISRCTN54137607 on 31 January 2005: http://www.isrctn.com/ISRCTN54137607) and ClinicalTrials.gov (NCT00125593 on 29 July 2005: https://clinicaltrials.gov/ct2/show/NCT00125593).

Deep Vein Thrombosis of Lower Extremities

In 150 patients with possible deep venous thrombosis in the lower extremities, the diagnostic accuracy of real time ultrasonography (US) with 3.5, 5.0 or 7.5 MHz transducers was assessed using venography as standard. In the area of the common femoral/popliteal vein, US was correct in 147 patients, giving an accuracy of 98 percent. There were no false negative studies, giving a sensitivity of 100 percent (60/60) and three false positive studies, giving a specificity of 97 percent (87/90). The results were almost the same using all the three frequencies. The simplicity and accuracy of US make it a useful diagnostic tool.

A transparent Pyrex μ-reactor for combined in situ optical characterization and photocatalytic reactivity measurements

A new Pyrex-based μ-reactor for photocatalytic and optical characterization experiments is presented. The reactor chamber and gas channels are microfabricated in a thin poly-silicon coated Pyrex chip that is sealed with a Pyrex lid by anodic bonding. The device is transparent to light in the UV-vis-near infrared range of wavelengths (photon energies between ~0.4 and ~4.1 eV). The absorbance of a photocatalytic film obtained with a light transmission measurement during a photocatalytic reaction is presented as a proof of concept of a photocatalytic reactivity measurement combined with in situ optical characterization. Diffuse reflectance measurements of highly scattering photocatalytic nanopowders in a sealed Pyrex μ-reactor are also possible using an integrating sphere as shown in this work. These experiments prove that a photocatalyst can be characterized with optical techniques after a photocatalytic reaction without removing the material from the reactor. The catalyst deposited in the cylindrical reactor chamber can be illuminated from both top and bottom sides and an example of application of top and bottom illumination is presented.

Increased levels of C-reactive protein and leukocyte count are poor predictors of anastomotic leakage following laparoscopic colorectal resection

INTRODUCTION

Laparoscopic procedure and fast-track regimen with short post-operative hospital stay are gaining ground in colorectal surgery. The aim of the present study was to determine whether the levels of C-reactive protein (CRP) and white blood cell counts (WBC) have a role as early predictors of post-operative septic complications including anastomotic leakage in patients operated laparoscopically in a fast-track regimen.

MATERIAL AND METHODS

This was a retrospective analysis of 129 patients who underwent laparoscopic colorectal surgery in a fast-track regimen during a one-year period. The levels of CRP and WBC were measured daily until discharge. The diagnostic accuracy was evaluated using the receiver-operating characteristics methodology.

RESULTS

The median post-operative hospital stay was three days. Septic complications occurred in 32% of cases. Post-operative CRP level was significantly higher in patients with septic complications than in patients without complications, but similar in patients with anastomotic leakage and patients with other septic complications. The best cut-off value for CRP level as a predictor of septic complications was observed on post-operative day (POD) 3, where CRP concentration > 200 mg/l had a sensitivity of 68% and a specificity of 74%. WBC measurements showed the best cut-off value on POD 2, where WBC > 12 × 10(9) had a sensitivity of 90% and a specificity of 62%.

CONCLUSION

The insufficient diagnostic accuracy of the levels of CRP and WBC made them weak diagnostic markers in prediction of post-operative septic complications, including anastomotic leakage, in the first three post-operative days after laparoscopic colorectal surgery.

High mass resolution time of flight mass spectrometer for measuring products in heterogeneous catalysis in highly sensitive microreactors

We demonstrate a combined microreactor and time of flight system for testing and characterization of heterogeneous catalysts with high resolution mass spectrometry and high sensitivity. Catalyst testing is performed in silicon-based microreactors which have high sensitivity and fast thermal response. Gas analysis is performed with a time of flight mass spectrometer with a modified nude Bayard-Alpert ionization gauge as gas ionization source. The mass resolution of the time of flight mass spectrometer using the ion gauge as ionization source is estimated to m/Δm > 2500. The system design is superior to conventional batch and flow reactors with accompanying product detection by quadrupole mass spectrometry or gas chromatography not only due to the high sensitivity, fast temperature response, high mass resolution, and fast acquisition time of mass spectra but it also allows wide mass range (0-5000 amu in the current configuration). As a demonstration of the system performance we present data from ammonia oxidation on a Pt thin film showing resolved spectra of OH and NH(3).

Linking Customer Interaction and Innovation: The Mediating Role of New Organizational Practices

The notion that firms can improve their innovativeness by tapping users and customers for knowledge has become prominent in innovation studies. Similar arguments have been made in the marketing literature. We argue that neither literatures take sufficient account of firm organization. Specifically, firms that attempt to leverage user and customer knowledge in the context of innovation must design an internal organization appropriate to support it. This can be achieved in particular through the use of new organizational practices, notably, intensive vertical and lateral communication, rewarding employees for sharing and acquiring knowledge, and high levels of delegation of decision rights. In this paper, six hypotheses were developed and tested on a data set of 169 Danish firms drawn from a 2001 survey of the 1,000 largest firms in Denmark. A key result is that the link from customer knowledge to innovation is completely mediated by organizational practices.

In vitro and in vivo evaluation of Dideco’s paediatric cardiopulmonary circuit for neonates weighing less than five kilograms

The neonate cardiopulmonary bypass (CPB) circuit, including a KIDS D100 oxygenator (The Sorin Group, Mirandola, Italy) and a D130 arterial filter (The Sorin Group), was evaluated in vitro with respect to the removal of free micro gas bubbles. No gas bubbles > 40µm were measured after the arterial filter D130 upon manual introduction of 10 ml of air into the venous line or during the use of vacuum-assisted venous drainage (VAVD). The D130 arterial filter removed 88 % of gas bubbles < 40 µm during manual introduction of air into the venous line; however, only 50 % of gas bubbles < 40 µm were removed during the use of VAVD.

The same CPB circuit was evaluated in vivo to compare with another CPB circuit, including a D901 oxygenator (The Sorin Group) and arterial filter D736 (The Sorin Group), in 155 neonates weighing ≤5 kg. The D100 circuit required significantly less priming volume than the D901 circuit. Postoperative haemoglobin was significantly higher, artificial ventilation time was significantly shorter and postoperative bleeding was significantly less in the D100 group. This neonate CPB circuit effectively removed the gas bubbles and required up to 37% less priming volume and, thus, decreased the need for blood transfusion.
