Citizen participation in police crisis intervention activities

A naturalistic experiment tested the proposition that police time could be saved in nondangerous crisis intervention calls through the use of citizen participants. Results showed that police officers who used citizen intervention spent less time per call than officers who did not. However, police time was not saved in family disturbance calls. Family disturbance control group calls were rated by police as having a higher degree of physical danger present than other calls.     

Couples Therapy Using the Technique of Construct Differentiation

A central problem in couples therapy is the clients' tendency to persist in endless and fruitless alternation between attacking the partner and justifying themselves. The technique of construct differentiation described in this article has proved helpful in coping with this situation. In three clearly structured steps, the therapist explores the personal constructs of each partner in the presence of the other. Instead of concentrating in the usual way on circularity of thoughts, feelings, and behavior, the partners are hindered from interacting and are confronted by the therapist's questions concerning their own inner process, independently of that of the partner. By becoming aware of their own ambivalent constructs and those of the partner, the eagerness to convert the partner to their own point of view can be reduced, and the construct system of each partner can be enriched by the other's constructs. Construct differentiation proves especially useful in the treatment of power struggles and narcissistic collusions.     

Matching the message to the process: the relative ordering of knowledge,attitudes, and practices in behavior change research

The authors empirically investigated the relative ordering of knowledge, attitudes, and practices in behavior change models and its relation to communicating health-related information. Considerable research has been conducted in the area of behavior change to identify and measure the presence of knowledge, attitudinal, and practice levels for many behaviors. The literature is reviewed. The authors' investigation consisted of interviewing 1680 men and women in Lima, Cusco, Huaraz, Puno, and Chimbote--5 large Peruvian cities--in 3 urban probability household surveys conducted in August 1994, January 1995, and January 1996. Six possible knowledge, attitude, and practice permutations are developed with regard to contraception in Peru. People may use contraceptive methods before they become fully knowledgeable about their chosen methods. In so doing, these users may become misinformed about contraceptive practice and become dissatisfied contraceptive users who discontinue contraceptive use. Media campaigns designed to inform the public can help produce a more satisfied and sustainable contraceptive user base. The informed choice approach can be the basis for effective communication strategies.     

Activation of lexical and syntactic target language properties in translation

Is reading for translation equal to reading in monolingual contexts? Horizontal/parallel theories of translation propose that normal reading and reading for translation differ because the translator engages in partial reformulation while reading for translating the source text. In contrast, vertical/serial theories assume that the translators first extract the meaning of the message, and only then they proceed to reformulate it. In two experiments, we manipulated lexical and syntactic properties of the target language (TL) while translators read for repetition or for translation. On-line sentence comprehension was affected by the lexical frequency of words in the TL (Experiment 1) and the syntactic congruency between the source language (SL) and TL sentences (Experiment 2). However, the influence of lexical and syntactic TL properties was restricted to the reading for translation task. According to our results, the horizontal view of translation includes code-to-code links between the SL and TL involving at least the lexical and syntactic level of processing.     

Reinforcement of wheel running in BALB/c mice: role of motor activity and endogenous opioids

The authors investigated the effect of the opioid antagonist naloxone on wheel-running behavior in Balb/c mice. Naloxone delayed the acquisition of wheel-running behavior, but did not reduce the expression of this behavior once acquired. Delayed acquisition was not likely a result of reduced locomotor activity, as naloxone-treated mice did not exhibit reduced wheel running after the behavior was acquired, and they performed normally on the rotarod test. However, naloxone-blocked conditioned place preference for a novel compartment paired previously with wheel running, suggesting that naloxone may delay wheel-running acquisition by blocking the rewarding or reinforcing effects of the behavior. These results suggest that the endogenous opioid system mediates the initial reinforcing effects of wheel running that are important in acquisition of the behavior.     

Neurotransmitter release during delay eyeblink classical conditioning: role of norepinephrine in consolidation and effect of age

Delay classical eyeblink conditioning (EBC) is an important model of associative, cerebellar-dependent learning. Norepinephrine (NE) plays a significant modulatory role in the acquisition of learning; however, other neurotransmitters are also involved. The goal was to determine whether NE, gamma-aminobutyric acid (GABA) and glutamate (GLU) release are observed in cerebellar cortex during EBC, and whether such release was selectively associated with training. Further studies examined the role of the beta-noradrenergic receptor in consolidation of the learned response by local infusion of propranolol at 5-120 min following training into the cerebellar cortex. In vivo microdialysis coupled to EBC was performed to examine neurotransmitter release. An increase in the extracellular level of NE was observed during EBC and was maximal on day 1 and diminished in amplitude with subsequent days of training. No changes in baseline NE release were observed in pseudoconditioning indicating that NE release is directly related to the associative learning process. The extracellular levels of GABA were also increased selectively during paired training however, the magnitude of GABA release increased over days of training. GLU release was observed to increase during both paired and unpaired training, suggesting that learning does not occur prior to the information arriving in the cerebellum. When propranolol was administered at either 5-, 60-, or 120-min post-training, there was an inhibition of conditioned responses, these data support the hypothesis that NE is important for consolidation of learning. In another set of experiments we demonstrate that the timing of release of NE, GABA and glutamate are significantly delayed in onset and lengthened in duration in the 22-month-old F344 rats. Over days of training the timing of release becomes closer to the timing of training and this is associated with increased learning of conditioned responses in the aged rats.     

Racial phenotypicality bias in educational expectations for both male and female teenagers from different socioeconomic backgrounds

In three experiments (N = 56, 99, and 225), we showed that racial phenotypicality bias characterizes educational expectations for Chilean mestizo students: participants displayed more positive educational expectations for light complexioned than for dark complexioned high school students. In Study 1, with male high school target students, the relation between racial phenotypic appearance and educational expectations was mediated by differences in perceived competence. Study 2 suggests that the gender of the target student did not influence the occurrence of racial phenotypicality bias. Study 3 showed that racial phenotypicality bias occurs in both university students and high school teachers' judgements. Although socioeconomic background of the target student partially explained the effects of racial phenotypic appearance (especially in teachers), the latter exerted an additional and independent influence on educational expectations. These results underline the fact that effects of racial phenotypicality bias should not be overlooked in the educational domain. As mediational analyses suggested, these effects only partly occur because of stereotypical associations between racial phenotypic appearance and socioeconomic background, but also because of stereotypical associations between racial phenotypic appearance and attributed competence.     

Expressions of Evangelism in Latin America

The purpose of this article is to explore the expressions of evangelism that are emerging in Latin America within the Evangelical‐Pentecostal context of the continent. We will do this by approaching our subject from the perspective of change, religious mutation and transformational change: we will first refer to the shift in evangelism and mission perspective in Latin America. We will explore the shift in numerical growth, then will deal with the shift in the concept and praxis of evangelism. This will be followed by a discussion on the shift from Western forms in church liturgy, music and hymnology to more contextual and indigenous expressions. Finally, I will refer to the shift toward holistic practices in times of turmoil and violence.
