Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

Imperialism,nationalism and missionaries: Lessons from Sudan for the twenty‐first century

Muslim‐Christian relations in modem Sudanese history involve the tensions created by the transition from imperial rule to independence and by the impact of contemporary processes of globalization. The conflicts between Christian missionaries and the newly‐independent government of Sudan in the early 1960s reflected the tensions between old mission‐station style Christian activities and attempts by a military régime to impose measures of ‘national’ unification. Opportunities for creating institutions for constructive interactions were missed or not even conceived. Lessons from the experiences of the early 1960s emphasize the importance of viewing Muslim‐Christian relations in the 1990s in the context of the actual current conditions rather than imposing out‐of‐date images on existing realities.     

The value of possessions in compulsive hoarding: Patterns of use and attachment

Hoarding behavior, patterns of use of possessions, and emotional attachment to possessions were examined among a sample of female undergraduates and a sample of community volunteers. Hoarding behavior was associated with a decreased frequency of use of possessions and excessive concern about maintaining control over possessions. Furthermore, high scores on the hoarding scale were associated with higher levels of perceived responsibility for: (1) being prepared; and (2) the well-being of the possession. Hoarding was also associated with greater emotional attachment to possessions and to the reliance on possessions for emotional comfort. The implications of these findings for the definition of hoarding are discussed.     

The effects of cocaine on behavior maintained by timeout from avoidance.

Rats were trained on concurrent schedules under which responses on one lever postponed shock (avoidance) and responses on the other lever produced brief (2-min) periods of signaled timeout from avoidance. For 6 rats, timeout from avoidance was programmed on a variable-interval 45-s schedule that generally resulted in rates that were lower than those on the avoidance lever. For another 6 rats, timeout was arranged on a variable-ratio 15 schedule that produced higher baseline rates. Cocaine (3 to 40 mg/kg) produced large, dose-dependent increases in behavior maintained by timeout in both groups of rats. Avoidance responding was also generally increased by cocaine, but the increases were of lesser magnitude. Increases in response rates were seen across a broad range of doses on behavior maintained by either interval or ratio schedules, an outcome that was unexpected on the basis of most studies of cocaine on food-maintained behavior. These results were similar to those of previous studies of the effects of amphetamine on behavior maintained by timeout from avoidance and suggest that stimulant drugs affect behavior maintained under a shock-postponement schedule differently than they affect behavior maintained by timeout from avoidance.     

Physicians' values and physician-value neutrality

For years articles have decried the lack of empathy in physicians' relationships with patients. In addition to being empathetic, physicians are called upon to assume the posture of value neutrality, i.e., not imposing one's values when dealing with patients. Empathy is clearly an expression of deeply held values; even the language used to define it is value-laden. Physicians are consistently called upon to exhibit traits which are expressions of their underlying values. However, if proponents of value-neutrality are to be taken literally one must not impose any of one's values on one's patients. But then one wonders how empathy could ever be expressed; further, it is hard to imagine what a truly value neutral physician would be like. It is time we recognize that any relationship between two persons requires the expression of values from both parties. These values help shape that relationship and define its further history. Physicians are not excluded from this process just because they consider themselves professionals. Divulging personal values to patients is both more honest and more in keeping with the concepts of justice, beneficence, non maleficence, and autonomy than to feign value-neutrality. A presentation of some type statement of values is timely and would give patients an idea of where a physician stands on a myriad of issues. Rather than being value-neutral, value non-neutrality seems a more right and reasonable posture for physicians to assume.     

A behavioral assessment scale for attention deficit disorder in brazilian children based on DSM-IIIR criteria

A teacher scale based on DSM-III-R diagnostic criteria for attention deficit hyperactivity disorder (ADHD) was developed for the behavioral assessment of children in Brazil. A total of 2, 082 children (782 males and 1,300 females) with a mean age of 11.2 years who were attending a public school in the greater Rio de Janeiro area were the subjects of this study. Two factors (Hyperactivity-Impulsivity and Inattention) were extracted from a principal-factor analysis conducted on the data, and the factor structure of the scale was found to be stable. Ratings of boys were higher than ratings of girls, and younger children had higher ratings than older children for both factors. Test-retest reliability for each item of the scale ranged from .56 to .70. The data are discussed in view of current controversies in the factor structure of teacher ratings of DSM-III-R ADHD symptoms.This research was supported by FINEP (42.88.0138.00) and FUNPENE.

Guedes for assistance in data analysis with the SAS and SPSS packages. The authors wish to thank the school staff and teachers who participated in the study.

Frame multiplicity and policy fiascoes: Limits to explanation

The dynamics of intractability, frame multiplicity and intense controversy not only characterize policy formation struggles, as described by Schön and Rein, but also affect the evaluation of policies and government action. Policy analysts play an important part in the politics of policy evaluation. This article demonstrates that they tend to produce very different explanations for controversial, failing policies. Such differing explanations imply different causal attributions, different allocations of blame, and different lessons for future policy-making. Such differences are not random occurrences; they are embedded in the analytical frames that evaluators use to reconstruct policy processes and to explain their outcomes. It is shown that at least three deep-rooted frames can be reconstructed: fiascoes as failures of public problem solving, fiascoes as institutional imbalances, and fiascoes as system artefacts. One of the great epistemological challenges is how to deal with multiple analytical frames. The final part of the article discusses various strategies.     

Perception of relative pitch with different references: Some absolute-pitch listeners can’t tell musical interval names

Two experiments were conducted to examine the effect of absolute-pitch possession on relativepitch processing. Listeners attempted to identify melodic intervals ranging from a semitone to an octave with different reference tones. Listeners with absolute pitch showed declined performance when the reference was out-of-tune C, out-of-tune E, or F#, relative to when the reference was C. In contrast, listeners who had no absolute pitch maintained relatively high performance in all reference conditions. These results suggest that absolute-pitch listeners are weak in relative-pitch processing and show a tendency to rely on absolute pitch in relative-pitch tasks.
