Effect of Emotional Cues on Memory Recall and Response Time

Combining electroencephalography, the recording of the brain\u27s electrical activity, with other psychological research techniques allows the link between memory and emotion to be investigated. This study, which is currently in the pilot phase, investigates the effect of emotions on performance in a memory test. Subjects are shown written memory cues with or without accompanying photos of strong facially-expressed emotions and later prompted to recall the written cues. By monitoring brain activity and recall success rate, emotion\u27s effect on memory in this context can be determined, including what brain regions are stimulated by the emotion-memory link and the improvement or impairment of memory skills under the effect of outside emotional cues

A Dwarf Form of \u3ci\u3eEuptoieta Claudia\u3c/i\u3e (Lepidoptera: Nymphalidae)

During a collecting vacation in August, 1970, I captured several specimens of Euptoieta claudia (Cramer). After spreading the catch, the interesting gradation shown in the accompanying photograph was noted. Figure 1 shows a wing span range from 1 318\u27\u27 \u27to 2

Moths Taken in Berrien County, Michigan (with 102 New County Records)

(excerpt) Moore (1955) published a listing of the moths of Michigan, exclusive of the Tineoidea, Other writers (anon., 1968; Voss, 1970) have extended the list of Michigan records. During the fall of 1970, and through the summer of 1971, I lived in Sawyer, Berrien County and collected a number of records new for that area. At the encouragement of M.C. Nielsen, a listing of these records is made available

Bilaterial equilibrium exchange rates of EU accession countries against the euro

We apply BEER and PEER approaches to calculate real equilibrium exchange rates for five EU accession countries in central and east Europe. Bilateral nominal equilibrium exchange rates against the euro are obtained through algebraic transformation of the results. Panel cointegration techniques are used to check the adequacy of the empirical model. The results reveal substantial overvaluations of the real exchange rate in several EU accession countries. Overvaluation is even higher when these exchange rates are expressed in nominal terms against the euro.real exchange rates, equilibrium exchange rates, transition economies, panel cointegration

Bounding the Inefficiency of Altruism Through Social Contribution Games

We introduce a new class of games, called social contribution games (SCGs), where each player's individual cost is equal to the cost he induces on society because of his presence. Our results reveal that SCGs constitute useful abstractions of altruistic games when it comes to the analysis of the robust price of anarchy. We first show that SCGs are altruism-independently smooth, i.e., the robust price of anarchy of these games remains the same under arbitrary altruistic extensions. We then devise a general reduction technique that enables us to reduce the problem of establishing smoothness for an altruistic extension of a base game to a corresponding SCG. Our reduction applies whenever the base game relates to a canonical SCG by satisfying a simple social contribution boundedness property. As it turns out, several well-known games satisfy this property and are thus amenable to our reduction technique. Examples include min-sum scheduling games, congestion games, second price auctions and valid utility games. Using our technique, we derive mostly tight bounds on the robust price of anarchy of their altruistic extensions. For the majority of the mentioned game classes, the results extend to the more differentiated friendship setting. As we show, our reduction technique covers this model if the base game satisfies three additional natural properties

Impact of consumer behavior on furan and furan-derivative exposure during coffee consumption : a comparison between brewing methods and drinking preferences

This study examined the influence of consumer behavior on furan, 2-methylfuran, 3-methylfuran, 2,5-dimethylfuran and 2,3-dimethylfuran exposure in coffee. Coffees brewed using a filter, fully automatic, capsule machine or reconstituted instant coffee were found to have a significant different cup concentrations of furan derivatives. Coffee brewed with the fully automatic machine contained the highest furan and furan derivative concentrations (99.05 µg/L furan, 263.91 µg/L 2-methylfuran, 13.15 µg/L 3-methylfuran and 8.44 µg/L 2,5-dimethylfuran) whereas soluble coffee did not contain detectable levels, thereby contributing least to a consumer’s dietary exposure. Furan and furan derivative concentrations were found to decrease significantly upon cooling, reducing consumer exposure by 8.0-17.2% on average once the coffee reached drinking temperature 55-60°C, in ceramic cups. Serving coffee in a ceramic or disposable cup were found to influence the cooling dynamics of the coffee but did not statistically influence the consumers exposure at a given temperature

Yang-Mills Equations of Motion for the Higgs Sector of SU(3)-Equivariant Quiver Gauge Theories

We consider SU(3)-equivariant dimensional reduction of Yang-Mills theory on spaces of the form R x SU(3)/H, with H equals either SU(2) x U(1) or U(1) x U(1). For the corresponding quiver gauge theory we derive the equations of motion and construct some specific solutions for the Higgs fields using different gauge groups. Specifically we choose the gauge groups U(6) and U(8) for the space R x CP^2 as well as the gauge group U(3) for the space R x SU(3)/U(1)xU(1), and derive Yang-Mills equations for the latter one using a spin connection endowed with a non-vanishing torsion. We find that a specific value for the torsion is necessary in order to obtain non-trivial solutions of Yang-Mills equations. Finally, we take the space R x CP^1 x CP^2 and derive the equations of motion for the Higgs sector for a U(3m+3) gauge theory.Comment: 21 pages, 4 figures; v2: figures added, references updated, published version (JMP
