It's what you do and the way that you do it: Team task,team size,and innovation-related group processes

This article describes a study of the relationships between team inputs (task type and team size) and team processes in 87 cross industry Portuguese teams, some of which had high and some low requirements to innovate. Team processes were measured using the Team Climate Inventory (TCI), which focuses on clarity of and commitment to team objectives, levels of participation, support for innovation, and quality emphases. Three hypotheses were tested. The first proposed that teams carrying out tasks with a high innovation requirement would have high scores on a measure of team processes. This was supported insofar as such teams reported higher levels of participation and support for innovation. The second hypothesis proposed that large teams would have poorer team processes. This hypothesis was confirmed. The third hypothesis concerned the interaction between size and innovation. The results suggested that large teams operating under a relatively high pressure to innovate have poorer team processes than large teams that do not have a high requirement to innovate.     

The global precedence effect is not affected in inhibition of return

This study assessed whether inhibitory processes occurring in IOR affect perceptual processing of hierarchically organised stimuli. Experiment 1 used a global/local task that presented stimuli to the left or the right side. Results showed a global task advantage and a larger interference in the local than in the global task—the global precedence effect (GPE). These effects were larger than in previous studies using centrally presented stimuli, which suggests a greater involvement of low spatial frequency analysis with peripheral than with central stimuli. Experiment 2 combined the global/local task with IOR. Results replicated those of Experiment 1 but there was no interaction with stimulus location. That is, the GPE was not affected in IOR. Thus, we conclude that the GPE and inhibitory processing occurring in IOR are subserved by different mechanisms.     

Dual-memory processes in crack cocaine dependents: The effects of childhood neglect on recall

Exposure to adversities during sensitive periods of neurodevelopment is associated with the subsequent development of substance dependence and exerts harmful, long-lasting effects upon memory functioning. In this study, we investigated the relationship between childhood neglect (CN) and memory using a dual-process model that quantifies recollective and non-recollective retrieval processes in crack cocaine dependents. Eighty-four female crack cocaine–dependent inpatients who did (N = 32) or did not (N = 52) report a history of CN received multiple opportunities to study and recall a short list composed of familiar and concrete words and then received a delayed-recall test. Crack cocaine dependents with a history of CN showed worse performance on free-recall tests than did dependents without a history of CN; this finding was associated with declines in recollective retrieval (direct access) rather than non-recollective retrieval. In addition, we found no evidence of group differences in forgetting rates between immediate- and delayed-recall tests. The results support developmental models of traumatology and suggest that neglect of crack cocaine dependents in early life disrupts the adult memory processes that support the retrieval of detailed representations of events from the past.     

The Distress of Citizen-Children with Detained and Deported Parents

In immigration enforcement, many undocumented immigrants with children are often detained and deported. But it is their US-born citizen-children that have been overlooked in immigration debates and enforcement policies and practices. Citizen-children are at risk for negative psychological outcomes when families are fractured and destabilized by arrest, detention, and deportation. The children risk being torn from their parents and, often, their undocumented siblings. To add to the small but growing empirical base on the effects of living under the threat of deportation and actual deportation of parents, we compared the psychological status of three groups of citizen-children: (1) a group living in Mexico with their deported parents; (2) a group in the US with parents affected by detention or deportation; and (3) a comparison group of citizen-children whose undocumented parents were not affected by detention or deportation. We compared children on self-report and parent-report measures of behavioral adjustment, depression, anxiety, and self-concept. Across the three groups we found elevated levels of distress, and differences between children who had experienced a parent’s detention or deportation and those who had not. We discuss findings in the context of children’s clinical needs, future research, and implications for immigration enforcement policy and practices.     

On a Definition of a Variety of Monadic ℓ-Groups

In this paper we expand previous results obtained in [2] about the study of categorical equivalence between the category IRL ₀ of integral residuated lattices with bottom, which generalize MV-algebras and a category whose objects are called c-differential residuated lattices. The equivalence is given by a functor ${{\mathsf{K}^\bullet}}$ , motivated by an old construction due to J. Kalman, which was studied by Cignoli in [3] in the context of Heyting and Nelson algebras. These results are then specialized to the case of MV-algebras and the corresponding category ${MV^{\bullet}}$ of monadic MV-algebras induced by “Kalman’s functor” ${\mathsf{K}^\bullet}$ . Moreover, we extend the construction to ?-groups introducing the new category of monadic ?-groups together with a functor ${\Gamma ^\sharp}$ , that is “parallel” to the well known functor ${\Gamma}$ between ? and MV-algebras.     

Relational and item-specific influences on generate–recognize processes in recall

The generate–recognize model and the relational–item-specific distinction are two approaches to explaining recall. In this study, we consider the two approaches in concert. Following Jacoby and Hollingshead (Journal of Memory and Language 29:433–454, 1990), we implemented a production task and a recognition task following production (1) to evaluate whether generation and recognition components were evident in cued recall and (2) to gauge the effects of relational and item-specific processing on these components. An encoding task designed to augment item-specific processing (anagram-transposition) produced a benefit on the recognition component (Experiments 1–3) but no significant benefit on the generation component (Experiments 1–3), in the context of a significant benefit to cued recall. By contrast, an encoding task designed to augment relational processing (category-sorting) did produce a benefit on the generation component (Experiment 3). These results converge on the idea that in recall, item-specific processing impacts a recognition component, whereas relational processing impacts a generation component.     

When actions speak volumes: The role of inferences about moral character in outrage over racial bigotry

Inferences about moral character may often drive outrage over symbolic acts of racial bigotry. Study 1 demonstrates a theoretically predicted dissociation between moral evaluations of an act and the person who carries out the act. Although Americans regarded the private use of a racial slur as a less blameworthy act than physical assault, use of a slur was perceived as a clearer indicator of poor moral character. Study 2 highlights the dynamic interplay between moral judgments of acts and persons, demonstrating that first making person judgments can bias subsequent act judgments. Privately defacing a picture of Martin Luther King, Jr. led to greater moral condemnation of the agent than of the act itself only when the behavior was evaluated first. When Americans first made character judgments, symbolically defacing a picture of the civil rights leader was significantly more likely to be perceived as an immoral act. These studies support a person‐centered account of outrage over bigotry and demonstrate that moral evaluations of acts and persons converge and diverge under theoretically meaningful circumstances.

On Bourbaki’s axiomatic system for set theory

In this paper we study the axiomatic system proposed by Bourbaki for the Theory of Sets in the Éléments de Mathématique. We begin by examining the role played by the sign \(\uptau \) in the framework of its formal logical theory and then we show that the system of axioms for set theory is equivalent to Zermelo–Fraenkel system with the axiom of choice but without the axiom of foundation. Moreover, we study Grothendieck’s proposal of adding to Bourbaki’s system the axiom of universes for the purpose of considering the theory of categories. In this regard, we make some historical and epistemological remarks that could explain the conservative attitude of the Group.
