Mnemonic-strategy reduction of prose-learning interference

One hundred and sixty college students read three fictitious biographical passages according to either imagery-mnemonic or no-strategy control instructions. In one mnemonic condition, subjects formed separate images involving each biographical name and its associated facts: in another mnemonic condition, the biographical name and its associated facts were integrated within a single composite image. Relative to an interference-control condition, integrated mnemonic subjects recalled more factual information, whereas separate mnemonic subjects did not. In addition, the recall of integrated mnemonic subjects was statistically no different from that of a noninterference control condition, whereas the recall of separate mnemonic subjects was lower. Both theoretical and educational implications of the results are discussed.

Successive reversals of a discriminated preference for signaled tailshock

Three rats received unmodifiable tailshock at random intervals in a shuttlebox. In a continuous-choice situation, Ss could choose between an auditory signal immediately preceding or immediately following the tailshock. Over repeated daily 3-h sessions, each S acquired a spatial discrimination indicating a strong preference for the signal preceding tailshock. This preference continued undiminished through two successive reversals of the position associated with signaled shock. This demonstration precludes explanations of the preference-for-signaled-shock phenomenon based upon primary reinforcement value or acquired value of the signal, position preferences, and overt modification of the aversiveness of the reinforcer through such means as postural adjustments. An explanation of recent failures to obtain the preference-for-signaled-shock effect is offered.     

Teaching Psychobiology at a Distance

Psychobiology is an area of knowledge that deals with the biological basis of behaviour. Its concretion as a specific area of study originates in the confluence and development of other areas such as physiological psychology, experimental and comparative psychology, ethology, biology and the neurosciences. For some, psychobiology would be that part of the neurosciences that deals with the study of the processes of emotion, motivation, cognition and learning. Others are of the opinion that it covers a much wider area, and that its objective is rooted in the study of all biological mechanisms that govern behaviour — and these, undertaken from a philogenetic and ontogenetic perspective.

In the last decade, we have witnessed the creation of psychobiology departments throughout the world. These departments participate in the teaching of faculties of medicine, psychology, biology and zoology. In some universities, these departments even contribute to the teaching imparted by the faculties of philosophy and educational sciences. Sooner or later, the universities teaching at a distance had to consider the creation of departments of psychobiology to attend to the up‐dating of the curriculum of diversive faculties.

In the National University of Education at a Distance, U.N.E.D. (Madrid, Spain) the teaching of psychobiology is entrusted to a department of the same name which started during the academic year of 1982–83. Even though the experience is very short to be able to advance a complete evaluation, the difficulties encountered in the organization of the form and content of different courses imparted by the department of psychobiology (D.P.) could be useful to the reader. Therefore, these difficulties must be understood within the educational model of teaching at a distance at U.N.E.D.     

Strong／weak limits and strong／weak differentials of multi-variable indeterminate forms. II： Supplementary annotations and analysis

Supplementary annotations on special forms 1to 4, discussion on the general characteristics of K(t) and K(t,t′), and analyses on two noticeable limits are presented in this part. It is demonstrated that strong and weak parabolic transforms can beemployed to change the standard form of a multi-variable indeterminate form into χ^mK type, hence to derive the standardformulae of the limit and the differential.     

Hong Kong University and Polytechnic Grants Committee

The political uncertainties surrounding Hong Kong's future as a British Crown Colony have not inhibited either the Hong Kong Government or its particular version of a University Grants Committee (UGC) system from devising and planning a continuing expansion of higher education at a time when most other countries are levelling off or contracting their own.This article deals with the many unique features of the Hong Kong situation of which perhaps the most important is the nature of the Hong Kong Government - traditionally colonial and potentially authoritarian, not elected yet highly sensitive to Chinese opinion both internally and externally, and highly efficient in most of its management activities in spite of a strongly laisser faire tradition.The Hong Kong UGC system is charged with much wider planning functions throughout higher education than elsewhere and is responsible for the polytechnic as well as the two universities - hence its trans-binary designation as the University and Polytechnic Grants Committee. While this has helped its overall planning and academic guidance roles, it has involved it in severe difficulties in relation to its basic financial role which requires it to develop methodologies of financial assessment of Polytechnic costs for which no overseas models exist. Its academic membership is still entirely from overseas, with inevitable repercussions on its ability to arrange adequate collective discussion and its reliance on its local secretariat who act as the Government's de facto Department of Higher Education.     

Activating lignite and sludge by electro-hydraulic impulse

1. Introduction At present, it is necessary to use fertilizer to ensure the stable and high agricultural productivity. However, as we all know, the fertilizer not only decreases the self-fertility of soil, but also is accompanied with pesticide. Food poisoning caused by remnant pesticide in fruits and vegetables is often reported, and in such cases, chronic poisoning is the majority. The remnant pesticide accumulates in body gradually, and then induces kinds of disease. As reported, the Miyu…
