Conflict and Conflict Management in Innovation Processes in the Life Sciences

Research on social conflicts in innovation processes has been rare, leaving an important research gap, as conflicts often arise in innovation processes and are even part of a researcher's everyday life. This study examines innovation and the variables of innovation success in the life sciences; it tests a conflict management model and examines the impact of both conflict type and conflict management style on innovation performance. This study surveyed 152 basic and applied researchers on their conflict management style through a multi‐method approach incorporating both survey and qualitative methods. The substantive aspects and relational effectiveness of conflict management styles were compared, considering their number of publications and patents, problem solution quality, project newness, conflict de‐escalation and communication. Applied researchers showed significantly more domination than did basic researchers, and a dominating conflict management style was significantly related to project newness. Moreover, problem solving was not always the most successful conflict management style. These findings have important practical implications for conflict management training and can help managers and researchers strengthen their co‐operation and improve productivity.     

Improving the usability of standard schemas

Due to the development of XML and other data models such as OWL and RDF, sharing data is an increasingly common task since these data models allow simple syntactic translation of data between applications. However, in order for data to be shared semantically, there must be a way to ensure that concepts are the same. One approach is to employ commonly usedschemas—called standard schemas —which help guarantee that syntactically identical objects have semantically similar meanings. As a result of the spread of data sharing, there has been widespread adoption of standard schemas in a broad range of disciplines and for a wide variety of applications within a very short period of time. However, standard schemas are still in their infancy and have not yet matured or been thoroughly evaluated. It is imperative that the data management research community takes a closer look at how well these standard schemas have fared in real-world applications to identify not only their advantages, but also the operational challenges that real users face.     

Effect of Auditory Waiting Cues on Time Estimation in Speech Recognition Telephony Applications

Previous empirical research in subjective time estimation and applied work in auditory interface design imply that designers can use auditory stimuli during system processing to manipulate users' perception of its duration. Two experiments investigate the effect of system response time (SRT) duration and rate of change of an auditory waiting cue on participants' subjective time estimates and perceived affect. The results showed that perceived SRT duration and ratings of perceived anxiety, stress, and impatience increased as ticking rate increased. However, with a slow rate (2-sec ticking), participants underestimated the duration of SRT, but indicated a significant increase in negative affect as compared with silent conditions. These results suggest that interface designers may reduce the subjective duration and negative affective states of SRT through carefully chosen, slow tempo system processing tones. The results of this research also stress the importance of thoughtful, informed interface design that makes contact with the empirical literature of the cognitive sciences.     

Factor structure and psychometric properties of the Injection Phobia Scale–Anxiety.

The present investigation examined the factor structure and psychometric properties of the Injection Phobia Scale–Anxiety (IPS-Anx). Principal components analysis of IPS-Anx items in Study 1 (n = 498) revealed a 2-factor structure consisting of Distal Fear and Contact Fear. However, CFA results in Study 2 (n = 567) suggest that a 1-factor structure may be more parsimonious. IPS-Anx scores demonstrated excellent reliability including test–retest over a 12-week period in Study 3 (n = 195). Supportive evidence for convergent and divergent validity of IPS-Anx scores was also found in Study 4 (n = 319), with strong associations with disgust propensity and sensitivity and weak associations with positive affect. Further evidence of validity was found in Study 5 (n = 1,674) because IPS-Anx scores discriminated those who have experienced fainting symptoms or avoided medical procedures from those without a history of such symptoms. In Study 6, data from Studies 2 through 5 were pooled, and the findings of Study 2 were replicated. The 1-factor model also fit the data well for men and women in Study 6. Lastly, IPS-Anx scores differentiated those with blood-injection-injury phobia (n = 39) from those without this phobia (n = 43) in Study 7. These findings suggest that the IPS-Anx has excellent psychometric properties, making it suitable for use in programmatic research on injection phobia. However, future research examining the validity of a short form of the scale with only the Contact Fear items may further improve the efficiency and utility of the IPS-Anx.

Influence of Preoxidation on High-Temperature Corrosion of a FeCrAl Alloy Under Conditions Relevant to Biomass Firing

Preoxidation of a commercial FeCrAl alloy (Kanthal APM) was evaluated as a surface modification approach to reduce alkali chloride-induced corrosion during biomass firing in power plants. Samples of the alloy preoxidized at 900 °C in O₂ or O₂ + 10 vol% H₂O, and at 1100 °C in O₂, were coated with KCl and exposed at 560 °C to a gas mixture comprising of 12 vol% CO₂, 6 vol% O₂, 3 vol% H₂O, 400 ppmv HCl and 60 ppmv SO₂. The oxide formed at 1100 °C showed no reactivity with the corrosive species. By contrast, all samples preoxidized at 900 °C suffered severe attack, resulting in formation of Fe-, Cr- and Al-containing corrosion products in a heterogeneous morphology, similar to non-preoxidized samples. The observed differences with respect to the degree of corrosion attack on the preoxidized samples are discussed in terms of the composition and thickness of the different types of Al₂O₃ layers obtained by the preoxidation treatment.     

Structural Test and Diagnosis for Graceful Degradation of NoC Switches

Networks-on-Chip (NoCs) are implicitly fault tolerant and due to their inherent redundancy they can overcome defective cores, links and switches. This effect can be used to increase yield at the cost of reduced performance. In this paper, a new diagnosis method based on the standard flow of industrial volume testing is presented, which is able to identify the intact functions of a defective network switch rather than providing only a pass/fail result for the complete switch. To achieve this, the new method combines for the first time the precision of structural testing with information on the functional behavior in the presence of defects. This allows to disable defective parts of a switch after production test and use the intact functions. Thereby, only a minimum performance decrease is induced while the yield is increased. According to the experimental results, the method improves the performability of NoCs since 56.86?% and 72.42?% of defects in two typical switch models only impair one switch port. Unlike previous methods for implementing fault tolerant switches, the developed technique does not impose any additional area overhead and is compatible with many common switch designs.     

A sensitive enzyme immunoassay (EIA) for the determination of melengestrol acetate (MGA) in adipose and muscle tissues

The development of a sensitive screening method of MGA residues in bovine perirenal fat and muscle based on a competitive microtitration plate enzyme immunoassay is described. The samples were extracted with petroleum ether and purified with octadecyl-silica-cartridges. The detection limit for fat was 0.4ng/g and for muscle tissue 0.05ng/g, much lower than required for reliable detection of positive samples. The mean recovery rates of fortified samples amount to 75%, the mean intraassay variations to 7% and the interassay variation to 13%. Determination limits were validated for fat at 2ng/g and for muscle at 0.1ng/g. The efficiency of the new screening method was successfully demonstrated by the direct comparison to GC-MS and LC-MS methods performed at natural positive samples originating from an animal experiment in which the labelled dose (0.5mg per animal and day) with and without a 48h withdrawal period or 3-fold or 10-fold the amount of MGA, respectively, was fed to Holstein Frisian heifers. In conclusion, this new screening method can be used for sensitive determination of MGA residues in adipose tissues even after low treatment doses or longer withdrawal periods.     

The Potential use of Silicon Isotope Composition of Biogenic Silica as a Proxy for Environmental Change

Silicon isotope geochemistry is a relatively new branch of environmental change research. Here we review the recent developments in the preparation of materials, analytical methods and applications of stable silicon isotope geochemistry in the most common types of biogenic silica currently being analysed. These materials are: diatom, radiolarian and siliceous sponges in lake and ocean sediments and plant phytoliths which are preserved in soils. Despite analyses of Si isotopes being carried out on rocks and minerals since the 1950's and the increasingly widespread use of Si isotopes since the 1990's, to date only a relatively small number of studies have applied Si isotope ratios to environmental change. In lake and ocean sediments the analysis of Si isotope ratios from biogenic materials has the potential to provide an important source of palaeoenvironmental information, especially where carbonates are not preserved. In plants and soils few studies have used Si isotopes, but important advances have recently been made in the understanding within plant fractionations. These may be useful in the application of Si isotopes in phytoliths to archaeological and palaeoenvironmental contexts.
