Over Time

At a certain point during the defocusing of a reversible figure, the organization of the figure reversed unexpectedly, and the reversal seemed more abrupt than a spontaneous reversal. The critical point is approximately constant over time for a given subject, and a similar point occurs during refocusing. This phenomenon is discussed in terms of inhibition between competing neural structures.

Participatory Observation

Language produced in a specific event of communication will have its form and function. Some messages are delivered in direct ways meaning the form and the functions are symmetric; some others are delivered in indirect ways, asymmetric. Direct or indirect ways will give different perceptions to those who receive the content of the message. Considering the face of receivers is one of the principles that should be made by policy makers as they communicate with people in public space. This article aims to explain the forms of language used to prohibit littering and the way the maker of prohibition thinks about the writing of littering. The research is conducted by using non-participatory observation method. This, then, is followed by applying note taking technique and recording. The result shows mostly the writings of littering prohibition are made an indirect way and less number in indirect way. Having a direct way means society is placed as subordinate in relation to the authorities. Even though less in number, indirect littering prohibition shows some writings see an equal position between the writer and reader. Both take a similar point of view on littering.

Old Friends

Some books are like parents, grandparents or old friends. They have been with us from our earliest days and one treats them almost with familiarity. They belong to one's youth and the recognition that they have been around for months and years keeps company with surprise. For philosophers such a book is A. J. Ayer's Language, Truth and Logic, first published over fifty years ago in 1936. There is a sense in which a similar point may be made about some individuals, but discretion and good manners should deter us from succumbing to the philosophical disease of pressing an analogy too far. Suffice it to say that over a period during which most English speaking philosophers were content (or perhaps constrained) to work within a context which was significantly influenced by Ayer's clear and cajoling formulation of a twentieth century of empiricism, F. C. Copleston provided one of the few distinctive alternative philosophical perspectives on major metaphysical questions. This essay will reflect upon the influence of Ayer's Language, Truth and Logic some fifty years after its publication, upon the philosophical discussion of religion and theological questions.

Having distinguished essentially fictional characters from inessentially fictional ones (a distinction I shall examine later) and having identified Anna Karenina as an inessentially fictional character, Barrie Paskins solves the problem I posed in ‘How Can We Be Moved by the Fate of Anna Karenina?’ thus: ‘our pity towards the inessentially fictional is, or can without forcing be construed as, pity for those people if any who are in the same bind as the character in the fiction’. Making a similar point in a footnote, ‘our emotions towards fictional characters are directed towards those real people, if any, who are in essentially the same situation’, he continues in the text, ‘This possibility is neglected by Radford and Weston.’

In the April, 1950 issue of The Mathematics Teacher William R. Ransom1 suggests a more meaningful approach to the teaching of combination of like terms than that usually found in the first course in algebra. The present paper describes an attempt to apply a somewhat similar point of view to the entire beginning course in algebra.

Bilingual Development

The study of bilingual development has been, and must be, an interdisciplinary endeavor; Carroll (Carroll) presents us with a perspective from within one particular discipline, that of generative linguistics. From this vantage point, she provides us perhaps most importantly with the reminder that language is not a unitary construct, and cautions against extrapolating from findings on the learning of one particular aspect of language, such as vocabulary, to language acquisition more broadly. I wholeheartedly agree (for a similar point, see Paradis & Grüter, 2014). I do not agree, however, with Carroll's implication that such unwarranted extrapolation is characteristic of current research on input and bilingual development. A number of recent studies have looked specifically at the differential relation between input (in a wide sense) and bilingual children's acquisition of different linguistic phenomena. Unsworth (2014), for example, reported different effects of input variation on Dutch–English bilingual children's acquisition of grammatical gender versus indefinite object scrambling.

Extragenic Suppressors

Abstract We selected and analyzed extragenic suppressors of mutations in four genes--GRR1, REG1, GAL82 and GAL83-required for glucose repression of the GAL genes in the yeast Saccharomyces cerevisiae. The suppressors restore normal or nearly normal glucose repression of GAL1 expression in these glucose repression mutants. Tests of the ability of each suppressor to cross-suppress mutations in the other glucose repression genes revealed two groups of mutually cross-suppressed genes: (1) REG1, GAL82 and GAL83 and (2) GRR1. Mutations of a single gene, SRG1, were found as suppressors of reg1, GAL83-2000 and GAL82-1, suggesting that these three gene products act at a similar point in the glucose repression pathway. Mutations in SRG1 do not cross-suppress grr1 or hxk2 mutations. Conversely, suppressors of grr1 (rgt1) do not cross-suppress any other glucose repression mutation tested. These results, together with what was previously known about these genes, lead us to propose a model for glucose repression in which Grr1p acts early in the glucose repression pathway, perhaps affecting the generation of the signal for glucose repression. We suggest that Reg1p, Gal82p and Gal83p act after the step(s) executed by Grr1p, possibly transmitting the signal for repression to the Snf1p protein kinase.
