Inducing knowledge sharing in teams through cost-efficient compensation schemes

A natural challenge for firms seeking to implement knowledge management systems is accounting for the interplay of incentives among workers and supervisors. This paper studies this interaction, focusing on the dynamics arising from joint projects, task evaluation, and knowledge sharing, in the framework of a game-theoretic model. We identify conditions under which a firm can minimize the costs of implementing an incentives-based system for knowledge sharing, taking into account the firm’s ability to monitor individual performance. We show that an employer in our framework has a stronger incentive to monitor tasks when relative-performance pay is small and when higher-paid agents are more likely to generate new knowledge.     

A managerial view of the knowledge flows of a health-care system

A health system has various knowledge structures enabling its knowledge resources to be efficiently applied. The literature has covered the management of clinical health information fairly extensively, but less is known about managerial knowledge flows. To address this knowledge gap, a regional health system in Finland is studied and managerial knowledge flows categorized in order to provide a better understanding of the inter-organizational knowledge networks of a health system. The paper contributes by illustrating and concretizing the knowledge dynamics of a health system. The empirical examination reveals the complexity of managerial knowledge flows and identifies three main categories of these: (1) national information steering, (2) regional information steering, and (3) internal control information. These categories are further elaborated with the data gathered through observation, interviews, and process modelling. A better understanding and management of knowledge flows is expected to have a positive effect on the performance of the health system.     

Narrating Your Work: an approach to supporting knowledge sharing in virtual teams

We propose an approach to enhancing knowledge sharing and connectedness in distributed teams. Termed ‘Narrating Your Work’ (NYW), the approach involves members of distributed team using a microblogging tool to post regular updates about their current work, accomplishments, and issues. The NYW approach was evaluated within a geographically and temporally distributed team at Shell International for a period of one month, using a mixed-method research design. Methodology comprised of a quantitative survey, followed by semi-structured interviews and analysis of microblogging updates posted during the month in which the approach was being trialled. The evaluation results suggest that NYW was viewed as a valid and practical approach to enhancing knowledge sharing and connectedness. A range of barriers and enablers that could impact the future application and embedding of the approach are identified and recommendations for implementation are outlined.     

The use of economic classifiers for the indexing of scientific publications

The experience from the application of the OKVED 2 economic classifier for indexing scientific publications is considered. More than 9500 articles on the subject of “Automation. Computer Engineering” in authoritative Russian magazines were the material for the study. Some means for the comparative analysis of economic statistics and results of the classification of scientific publications are shown.     

Adolescents and Movie Ratings: Is Psychological Reactance a Theoretical Explanation for the Forbidden Fruit Effect?

Adolescents were recruited to participate in an experiment to assess whether psychological reactance can provide a theoretical explanation for the forbidden fruit effect in the context of movie rating restrictions. In addition to examining if movie ratings served as antecedents to freedom threat perceptions, we investigated the role authoritarian parents had on freedom threat perception and reactance arousal. Results indicated that a movie with an NC-17 rating was perceived as a stronger freedom threat than R and PG-13 rated movies. Interestingly, adolescents who perceived their parents to be authoritarian were less likely to view movie ratings as a freedom threat. As expected, freedom threat perceptions were positively associated with psychological reactance. Reactance, in turn, was positively associated with both first and third person attitudes. The results are discussed with an emphasis on the theoretical and practical implications of the findings.     

Gay On-Screen: The Relationship Between Exposure to Gay Characters on Television and Heterosexual Audiences' Endorsement of Gay Equality

The current study, grounded in the parasocial contact hypothesis, employed a survey of emerging adults to investigate the relationship between exposure to gay characters on television and heterosexuals' endorsement of gay equality. A positive relationship existed between exposure to on-screen gay characters and gay equality endorsement. The relationship was stronger for racial minority participants than for White participants, and for participants who had no or few interpersonal relationships with openly gay individuals than for participants who had more than three respective relationships. Results are discussed in terms of the parasocial contact hypothesis and television as an agent of social change.     

Shifting the Perspective of the Research Librarian: A CoResearch Paradigm

This article proposes the coresearch engagement model (CoRE), which addresses how the academic research librarian can become a coresearch partner with any patron. The CoRE model is an interpersonal process and is founded upon the concepts of mutual respect, collaboration, reciprocity, and empowerment. Grounded in Howard Gardner’s multiple intelligences theory, Malcolm Knowles’ andragogical model, and guidelines from the Reference and User Services Association, CoRE has the potential to result in engagement for the librarian and patron. The CoRE model can be utilized in many ways including self-awareness and development for those who need and want to expand their abilities as a research librarian. It provides a theoretical framework and a knowledge base, in addition to giving a context for further development by expanding, comparing the related theories for further research, and implementing various applications suggested by this article.     

Thermally multiplexed polymerase chain reaction

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.     

Biofunctionalized nanoslits for wash-free and spatially resolved real-time sensing with full target capture

We propose biofunctionalized nanofluidic slits (nanoslits) as an effective platform for real-time fluorescence-based biosensing in a reaction-limited regime with optimized target capture efficiency. This is achieved by the drastic reduction of the diffusion length, thereby a boosted collision frequency between the target analytes and the sensor, and the size reduction of the sensing element down to the channel height comparable to the depletion layer caused by the reaction. Hybridization experiments conducted in DNA-functionalized nanoslits demonstrate the analyte depletion and the wash-free detection ∼10 times faster compared to the best microfluidic sensing platforms. The signal to background fluorescence ratio is drastically increased at lower target concentrations, in favor of low-copy number analyte analysis. Experimental and simulation results further show that biofunctionalized nanoslits provide a simple means to study reaction kinetics at the single-pixel level using conventional fluorescence microscopy with reduced optical depth.
