Software algorithm for automatic interpretation of mass spectra of glycerolipids

RAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 19 2002
J.-P. Kurvinen
A new software algorithm for automatic interpretation of mass spectra of glycerolipids has been developed. The algorithm utilizes a user-specified list of parameters needed to process the spectra. The compounds in mass spectra are identified according to range of measured m/z values, after which the spectra are automatically corrected by the content of naturally occurring isotopes and ion intensities of identified compounds by response correction factors. Automatic processing of the spectra was shown to be accurate and reliable by testing with numerous spectra of glycerophospholipids obtained by liquid chromatography/electrospray ionization mass spectrometry and by comparing the results with manual interpretation of the spectra. If quantitative analysis using internal standards is performed, all the identified compounds in the sample are quantified automatically. A dilution factor may be defined for each sample and is applied to correct the alterations in sample concentration during sample preparation. Processing of several replicate spectra simultaneously produces mean results with standard deviations. The software may also be used to subtract the results of two analyses and to calculate the mean result of replicate subtractions. The algorithm was shown to save time and labor in repetitive processing of mass spectra of similar type. It may be applied to processing of spectra obtained by various mass spectrometric methods.

Cooling the heat of temptation: Mental self-control and the automatic evaluation of tempting stimuli

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 1 2010
Wilhelm Hofmann
The present research investigated whether mental self-control strategies can reduce the automatic positivity elicited by tempting stimuli. In two studies employing chocolate as the temptation of interest, we found that participants instructed to imagine a chocolate product in a nonconsummatory manner exhibited significantly less automatic positivity with regard to the product as compared to participants instructed to imagine the hedonic, consummatory aspects of the product and control participants engaged in a neutral task. These findings were replicated in a second study. Additionally, in Study 2 we found that automatic evaluations of chocolate were lowest for participants instructed to form implementation intentions to refrain from consumption. Taken together, these findings demonstrate that mental self-control strategies such as nonconsummatory transformation and implementation intentions extend to the level of automatic processing by reducing the positivity of automatically activated affective responses.

Wiki a la carte: Understanding participation behaviors

PROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2007
Pnina Shachaf Organizer
This panel focuses on trends in research on Wikis. Wikis have become prevalent in our society and are used for multiple purposes, such as education, knowledge sharing, collaboration, and coordination. Similar to other popular social computing tools, they raise new research questions and have attracted the attention of researchers in information science. While some focus on the semantic web, the automatic processing of data accumulated by users, and tool improvements, others discuss social implications of Wikis. This panel presents five studies that address the social uses of Wikis that support information sharing. In their studies, the panelists use a variety of novel applications of research methods, such as action research, and online ethnography, site observation, survey, and interviews. The panelists will present their findings: Shachaf and Hara will discuss Wikipedians' norms and behaviors; Bonk will present collaborative writing on Wikibook; Mackey will discuss authorship and collaboration in PBwiki.com; Hemminger will share results from the early use of wikis for conference communications; and Stvilia will outline the community mechanism of information quality assurance in Wikipedia.

Electromagnetic brain activity evoked by affective stimuli in schizophrenia

PSYCHOPHYSIOLOGY, Issue 5 2006
Brigitte Rockstroh
Abstract Schizophrenia is typically associated with cognitive deficits, but symptoms also point to alterations in the processing of affective material, with potential impact on behavioral performance. This impact may unfold on multiple time scales, but initial processing of rapidly unfolding social cues may be particularly important. MEG-assessed regional brain activity associated with the capacity to process the emotional content of rapid visual stimuli (3/s) was examined in 12 individuals with schizophrenia and 12 matched controls. Patients showed less differentiation of emotional versus neutral stimuli 90,300 ms following picture onset. Together with group differences in the lateral topography of valence effects, these results are discussed as evidence of deficient automatic processing of emotionally potent stimuli in schizophrenia.

The effect of implementation intentions on prospective memory performance across the lifespan

APPLIED COGNITIVE PSYCHOLOGY, Issue 5 2010
Thomas D. Zimmermann
Differences in the amount and availability of cognitive resources may be responsible for age-related differences in event-based prospective memory tasks. We hypothesised that a manipulation which reduces resource requirements by enhancing automatic processing will reduce age differences. Implementation intentions are assumed to satisfy this requirement. We tested a total of 563 participants, 185 adolescents, 193 young adults and 185 older adults in order to investigate whether providing participants with implementation intention instructions would improve performance, whether any improvement would vary with age, and whether it would affect the prospective component or the retrospective component. The results showed a benefit of implementation intentions for older adults, but not for adolescents and for young adults. Separate analyses for the prospective and the retrospective components revealed that this effect was based mainly on a performance facilitation of the prospective component. These results suggest that implementation intentions provide a means to reduce age differences in prospective memory. Copyright © 2009 John Wiley & Sons, Ltd. [source]
