Transition Field

The Gauss-Matuyama (G-M) polarity transition has been identified in a 9 cm rotary-drilled core from Scaries Valley, California. The lithology, recovery and preservation of the sediments allow a detailed investigation of the transition. The transition is estimated to have lasted approximately 2000 years. About 2000 years earlier, a short reversal also occurred that lasted 2000 years. The relative field intensity decreased by at least 70 % both during this short reversal and the G-M transition. The virtual geomagnetic poles path for the G-M transition is restricted to a meridional band 20° wide in the Atlantic Ocean and closely matches the v.g.p. path for the Matuyama-Brunhes transition recorded at Lake Tecopa, California. On the other hand, the pole path for the G-M transition recorded in Russia (about 180° in longitude from Searles Valley) is nearly antipodal at low latitudes to the Learies Valley pole path. These data indicate that the transition field associated with the reversal was dominated by non-dipole components.

Arriving to the «new world» across the Atlantic Ocean from England, the Founding Fathers, as an act of thankfullness to God’s guidance, called the United States the «God’s Country». On the other hand, serious scholars would call them the «unfinished country» and quite a few political scientists would talk about «our more perfect Union», touching on the variety and contradictions of the Two-centuries and a half old «nation of nations».

Conceived as a symbolic gift to honor Teatr Reduta on the 100th anniversary of its inception and dedicated to the memory of recently passed theatre historian, Zbigniew Osinski, this extensive volume does more than commemorate and celebrate. It advances the studies of one of the most original and deeply influential undertakings in Polish theatre, which, despite securing its emblematic place in histry, deserves a closer analysis from the contemporary perspective, and further dissemination among scholars and practitioners. Reading the book from across the Atlantic Ocean, I will add, that this need for continued rethinking of theatre in dialogue with Osterwa and Limanowski in current Polish cultural and political context seems to be as important as challenging. On the one hand, religious and spiritual underpinnings of Reduta may be particularly susceptive to “committed” interpretations, to use Adorno’s term. On the other hand, memories bring the threat of nostalgia and sentimentalism which help to mythologize rather than analyze unique phenomena. Has Reducie na stulecie managed to stay free from these historiographic traps? What value do these history lessons bring to us today

Although a large share of attention has been given to the elucidation if the causes which influence the amount of carbonic acid present in he atmosphere during the day, no systematic observations with reference to the relative quantities present in the air of the land during the day and the night appear to have been undertaken since the well known experiments of the younger De Saussure at Chambeisy, upwards of 50 years ago (1820-30), and a similar set by Boussingault at Paris, a few years later, until M. Truchot took up the question in 1873. But the results thus obtained cannot be said to be altogether satisfactory. On the other hand, the question as to the existence of a diurnal variation in the amount of carbonic acid in sea-air may be said to have been fully worked out and set at rest by the careful and extensive set of observations made some years ago by Dr. Thorpe§ on the air of the Irish Sea and Atlantic Ocean. His results went to show that no appreciable diurnal difference exists.

Sudden Rise

AbstractWe have developed a model for theH2OandOHevolution in a comet outburst, assuming that together with the gas, a distribution of icy grains is ejected. With an initial mass of icy grains of 108kg released, theH2OandOHproductions are increased up to a factor two, and the growth curves change drastically in the first two days. The model is applied to eruptions detected in theOHradio monitorings and fits well with the slow variations in the flux. On the other hand, several events of short duration appear, consisting of a sudden rise ofOHflux, followed by a sudden decay on the second day. These apparent short bursts are frequently found as precursors of a more durable eruption. We suggest that both of them are part of a unique eruption, and that the sudden decay is due to collisions that de-excite theOHmaser, when it reaches the Cometopause region located at 1.35 × 105kmfrom the nucleus.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.

Life beyond 1MeV – like life after 40 – is not too different unless one takes advantage of past experience and is receptive to new opportunities. At first glance, the returns on performing electron microscopy at voltages greater than 1MeV diminish rather rapidly as the curves which describe the well-known advantages of HVEM often tend towards saturation. However, in a country with a significant HVEM capability, a good case can be made for investing in instruments with a range of maximum accelerating voltages. In this regard, the 1.5MeV KRATOS HVEM being installed in Berkeley will complement the other 650KeV, 1MeV, and 1.2MeV instruments currently operating in the U.S. One other consideration suggests that 1.5MeV is an optimum voltage machine – Its additional advantages may be purchased for not much more than a 1MeV instrument. On the other hand, the 3MeV HVEM's which seem to be operated at 2MeV maximum, are much more expensive.

Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

Group Memberships

Abstract. Not all group memberships are self-chosen. The current research examines whether assignments to non-preferred groups influence our relationship with the group and our preference for information about the ingroup. It was expected and found that, when people are assigned to non-preferred groups, they perceive the group as different to the self, experience negative emotions about the assignment and in turn disidentify with the group. On the other hand, when people are assigned to preferred groups, they perceive the group as similar to the self, experience positive emotions about the assignment and in turn identify with the group. Finally, disidentification increases a preference for negative information about the ingroup.
