NaBH4 does not absorb NH3 below 100 kPa, but becomes liquid state after NH3 absorption. On the other hand, LiBH4 absorbs NH3 at lower pressure than 100 kPa. Interestingly, the...

This chapter provides an analytical and normative framework for evaluating the civil litigation system as well as for understanding existing critiques of the system. It argues that civil justice requires, first, that courts are accessible to parties with valid legal claims and defenses and, second, that courts are capable of distinguishing between strong and weak claims and defenses, which the chapter defines as reliability. This chapter also explains the central importance of litigation costs, and notes that on the one hand litigation costs can impede access to the courts, while on the other hand some costs are crucial to the operation of the civil litigation system—in that distinguishing between strong and weak claims requires certain expenditures.

Chapter 9 discusses legal socialization within the juvenile justice system. Adolescence is a developmental period during which many young people have contact with legal authorities, primarily the police. These contacts involve high levels of discretion for law enforcement, and studies show the manner in which that discretion is exercised has strong consequences for the subsequent orientations that adolescents have toward the law as well as their later law-related behavior. In particular, adolescents react to how fairly the authorities treat them. Juvenile justice is a particularly contentious area of policy with many punitive practices advocated in spite of evidence that they do not build legitimacy or reduce crime. On the other hand, experiencing justice is shown to promote legitimacy and lower offending.

Ancient Sanskrit had two tenses of particular interest: periphrastic perfect and periphrastic future. At first glance, they are rather similar: both realize a particular value of tense through a combination of a lexical verb (devoid of personal agreement) and an agreeing auxiliary. There are, however, important differences which are revealed in this chapter: the periphrastic future is available for every verb, and can be distinguished from the synthetic future on semantic grounds, while the periphrastic perfect is available only for certain verbs, and these do not make up a semantically homogeneous group. A formal analysis is proposed, within Paradigm Function Morphology, for the two periphrastic tenses. It is demonstrated that a morphological rather than a purely syntactic account is preferable here. The verbs with a periphrastic perfect make up a conjugation class; on the other hand, the periphrastic future is formalized as a morphosyntactic property whose default realization is periphrastic.

A new superconducting phase has been found in a mixed system prepared from the YBa 2 Cu 3 O 7−δ and Bi 2 CaSr 2 Cu 2 O 9−δ high-T c materials. The new compound shows an onset of resistivity transition at ~100 K and zero resistivity below ~50 K. Powder X-ray diffraction pattern of the new compound differs completely from those of YBa 2 Cu 3 O 7−δ and Bi 2 CaSr 2 Cu 2 O 9−δ. The materials prepared using a mixture of the oxides and carbonates with identical cation stoichiometric ratios, on the other hand, does not exhibit superconductivity.

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.

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.

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.
