The Effects of Numbered Heads Together with and Without an Incentive Package on the Science Test Performance of a Diverse Group of Sixth Graders

A clear and consistent finding of educational research has been the importance of active student responding. During lectures and discussions, active responding most often takes the form of student responses to teacher questions. This whole group responding to questions, however, does not permit every student to respond and does not assure that all students are actively engaged. Previous research has shown that Numbered Heads Together is an efficient and effective instructional technique to increase student responding and to improve achievement. Using an A-B-BC-B-BC design, we examined the effects of two versions of Numbered Heads Together on 6th graders daily quiz scores and pretest-posttest performance in chemistry. Findings indicated that the addition of a behavioral incentive package noticeably improved student performance during Numbered Heads Together instruction. Implications are discussed for teachers and educational researchers.     

The differential contributions of visual imagery constructs on autobiographical thinking

There is a growing theoretical and empirical consensus on the central role of visual imagery in autobiographical memory. However, findings from studies that explore how individual differences in visual imagery are reflected on autobiographical thinking do not present a coherent story. One reason for the mixed findings was suggested to be the treatment of visual imagery as an undifferentiated construct while evidence shows that there is more than one type of visual imagery. The present study investigates the relative contributions of different imagery constructs; namely, object and spatial imagery, on autobiographical memory processes. Additionally, it explores whether a similar relation extends to imagining the future. The results indicate that while object imagery was significantly correlated with several phenomenological characteristics, such as the level of sensory and perceptual details for past events – but not for future events – spatial imagery predicted the level of episodic specificity for both past and future events. We interpret these findings as object imagery being recruited in tasks of autobiographical memory that employ reflective processes while spatial imagery is engaged during direct retrieval of event details. Implications for the role of visual imagery in autobiographical thinking processes are discussed.     

Living and Working Together in Organizations: Traces and Ways

This article explores the state of the art in relation to the theme of living and working together in organizations and proposes a new theoretical model. A thorough examination of literature highlights that there are almost no works specifically coping with this theme, defining its theoretical perspective and specifying the choice of proposed indicators. Several, instead, are the works indirectly dealing with living and working together in organizations, mostly considered equivalent to the quality of interpersonal relationships, or developed starting from the theme of diversity and conflict. In reference to the social context, an important defining effort was carried out by Renzo Carli, who defines living together [convivenza in Italian] as the symbolic component of a social relationship, generated by three components: belonging systems, strangers and rules of the game. Living together means integrating these three elements of a relationship in order to create innovative products. This article proposes a review of this model, specifically designed for the organizational field. Living and working together in organizations is meant as the result of the cross among Identity, Otherness, and Work Purpose, within specific organizational Cultures of Diversity. Starting from this model, in dialogue with long-lasting research and intervention experience in various organizational contexts, we propose forms of living and working together in organizations that were empirically pointed out: generative-efficient, affiliating, performance-based, and chaotic-paralyzing styles.     

Revealing the Difference: Between Conflict Mediation and Law Enforcement—Living and Working Together as a Conceptual and Methodological Turning Point to Activate Transformation in a Juvenile Criminal Mediation Service

This article aims at proposing the construct of living and working together in organizations as an interpretation and tool proposed in a Juvenile Criminal Mediation Service, in order to highlight how important it was as a turning point in activating the working group's reflexive function as far as their sense of belonging, otherness, culture of diversity, and work subject matter are concerned and start an important transformation process in the very service delivery. Our proposal finds its roots in a follow-up experience regarding the aforementioned service, which has been taking place for almost three years. It was structured in three different phases: a research phase evaluating process and results of the activity that was carried out; a phase of monitoring the mediation practice; a research-action phase in a clinical perspective on the working group's operating mode. The leverage of living and working together in organizations is specifically proposed as far as this last working phase is concerned, lasting approximately ten months.     

回忆过去和想象将来时谈及他人与心理理论的关系

为考察心理理论与回忆过去、想象将来中内容的关系,153名青少年两周内完成了情景记忆和心理理论等任务。控制了智力、言语能力和执行功能后,线性回归分析发现青少年回忆过去和想象将来时“谈及他人”与心理理论有显著关联（Aajusted R^2=51．6％,F（9,143）=19．00,P〈0．001）,不同群体间心理理论的差异也可由其谈及他人数量不同来解释。结果提示。与西方谈论心理状态不同,中国文化下回忆过去和想象将来时“谈及他人”可能是促进心理理论发展的机制。

Training preschool children to use visual imagining as a problem-solving strategy for complex categorization tasks

It has been suggested that verbally sophisticated individuals engage in a series of precurrent behaviors (e.g., covert intraverbal behavior, grouping stimuli, visual imagining) to solve problems such as answering questions (Palmer, 1991; Skinner, 1953). We examined the effects of one problem solving strategy--visual imagining--on increasing responses to intraverbal categorization questions. Participants were 4 typically developing preschoolers between the ages of 4 and 5 years. Visual imagining training was insufficient to produce a substantial increase in target responses. It was not until the children were prompted to use the visual imagining strategy that a large and immediate increase in the number of target responses was observed. The number of prompts did not decrease until the children were given a rule describing the use of the visual imagining strategy. Within-session response patterns indicated that none of the children used visual imagining prior to being prompted to do so and that use of the strategy continued after introduction of the rule. These results were consistent for 3 of 4 children. Within-session response patterns suggested that the 4th child occasionally imagined when prompted to do so, but the gains were not maintained. The results are discussed in terms of Skinner's analysis of problem solving and the development of visual imagining.     

Interfaith Dialogue

The modern ecumenical movement initially sprang from the missionary movement. This led to considerable struggle within the ecumenical movement over embracing interfaith dialogue as a main focus of its ministry. This focus was eventually accepted, and since then the ecumenical movement has done much to promote interfaith relations at the local, national, and global level; to struggle with the theological issues such dialogue presents for the Christian faith; and to collaborate with other religions to reflect on common issues faced by the global community. Current Dialogue has played a major role in promoting the dialogue concern.
