Occupational information: What children want to know

The present exploratory-descriptive cross-national study focuses on what information children believe they need to find out about jobs. In total, 511 South African and 372 Australian children participated in the study. The present paper reports on the findings related to one item of the Revised Career Awareness Survey used in the study. Data were analyzed using descriptive statistics. The study revealed that the nature of information the children needed to find out was related to life/career implications and life/career management tasks and to a lesser extent to interests and personal characteristics and the nature of work. The implications of the findings for career guidance and counseling practice are discussed.

Secondary school support teachers' perception of speech-language pathology services to adolescents

A survey was conducted to investigate secondary school support teachers' perceptions of speech-language pathology services to students experiencing language difficulties. Information was sought regarding support teachers' understanding of language disorder, their experience with students who have language difficulties and their involvement with speech-language pathologists with regard to these students. Support teachers' views on supporting adolescents who are experiencing language difficulties were also sought as well as information regarding their satisfaction with speech-language pathology services to adolescents. Findings indicated variations in support teachers' perceptions, including mixed views regarding how speech-language pathologists should offer assistance to students. The need for support teachers and speech-language pathologists to offer each other professional training was indicated.

The state-contingent approach to production under uncertainty

The central claim of this paper is that the state-contingent approach provides the best way to think about all problems in the economics of uncertainty, including problems of consumer choice, the theory of the firm, and principal-agent relationships. This claim is illustrated by recent developments in, and applications of, the state-contingent approach.

Formant-Frequency Variation and Informational Masking of Speech by Extraneous Formants : Evidence Against Dynamic and Speech-Specific Acoustical Constraints

How speech is separated perceptually from other speech remains poorly understood. Recent research indicates that the ability of an extraneous formant to impair intelligibility depends on the variation of its frequency contour. This study explored the effects of manipulating the depth and pattern of that variation. Three formants (F1+F2+F3) constituting synthetic analogues of natural sentences were distributed across the 2 ears, together with a competitor for F2 (F2C) that listeners must reject to optimize recognition (left = F1+F2C; right = F2+F3). The frequency contours of F1 − F3 were each scaled to 50% of their natural depth, with little effect on intelligibility. Competitors were created either by inverting the frequency contour of F2 about its geometric mean (a plausibly speech-like pattern) or using a regular and arbitrary frequency contour (triangle wave, not plausibly speech-like) matched to the average rate and depth of variation for the inverted F2C. Adding a competitor typically reduced intelligibility; this reduction depended on the depth of F2C variation, being greatest for 100%-depth, intermediate for 50%-depth, and least for 0%-depth (constant) F2Cs. This suggests that competitor impact depends on overall depth of frequency variation, not depth relative to that for the target formants. The absence of tuning (i.e., no minimum in intelligibility for the 50% case) suggests that the ability to reject an extraneous formant does not depend on similarity in the depth of formant-frequency variation. Furthermore, triangle-wave competitors were as effective as their more speech-like counterparts, suggesting that the selection of formants from the ensemble also does not depend on speech-specific constraints.

A környezethez való jog és a Kiotói Jegyzőkönyv (Right to environment and Kyoto Protocol)

A Kiotói Jegyzőkönyv az 1992-ben Rio de Janeiro-ban megrendezésre került Környezet és Fejlődés Világkonferenciáján elfogadott nyilatkozatának 1997-ben aláírt kiegészítő jegyzőkönyve. A Kiotói Jegyzőkönyvben minden aláíró ország vállalta, hogy egy bizonyos százalékos arányban csökkenti országában a kibocsátott üvegházhatást okozó gázok mennyiségét, ezáltal mérsékelve a globális felmelegedés előrehaladtát. A Jegyzőkönyvhöz az Egyesült Államok és több fejlő ország, mint Kína vagy India gazdasági megfontolásból másrészt politikai szűklátókörűségből nem csatlakozott. Ez azonban a komoly aggályokat vet fel azzal kapcsolatban, hogy a környezetvédelmi szabályokat betartó államok erőfeszítései önmagában elegendőek lesznek-e a globális felmelegedés megállítására, de legalábbis csökkentésére. _____________ The Kyoto Protocol signed in the Japanese city in Kyoto in 1997 is a supplemental document to the United Nations Conference on Environment and Development organized in Rio de Janeiro. In the Kyoto Protocol individual countries have mandatory emissions targets for the greenhouse gases they must meet to slow down global warming. The United States of America, and several developing countries, as China and India did not yet joined the Protocol partly because of economic reasons and other ways because of narrow-minded political interests. This brings up serious doubt weather the efforts of the parties of the Protocol can make any change in the recent global processes.
