Duality Theory and Skeleta for Semisimple MV-Algebras

We start from Marra–Spada duality between semisimple MV-algebras and Tychonoff spaces, and we consider the particular cases when the \(\omega \)-skeleta of the MV-algebras are restricted in some way. In particular we consider antiskeletal MV-algebras, that is, the ones whose \(\omega \)-skeleton is trivial.     

Eliciting information and cues to deception using a model statement: Examining the effect of presentation modality

Forensic interviewing involves gathering information from a suspect or eyewitness. Administering a model statement during an interview results in greater information elicitation, which can enhance lie detection. Typically, a model statement is a highly detailed statement, on an unrelated topic to that of the interview. This study examined the effect of manipulating the modality of the MS, either by allowing participants to listen to (Audio‐MS), or read (Written‐MS) a model statement. A total of 162 (81 truth tellers, 81 liars) participants were randomly allocated to one of three interviewing conditions where they received either the Audio‐MS, Written‐MS, or No‐MS (control condition). Truth tellers honestly reported a “spy” mission, whereas liars performed a covert mission and lied about their activities. Results showed both model statements were equally more effective at eliciting information and facilitating lie detection, compared with a control condition. Theoretical and practical implications are discussed.     

Radical hope in revolting times: Proposing a culturally relevant psychological framework

Growing research supports the link between individual expressions of hope and psychological well‐being. In this paper, we draw on psychological theories of hope, racial and ethnic studies, and the literature on radical healing to propose a framework of radical hope. Although the proposed multidimensional framework integrates cultural practices of People of Color in the United States, it is flexible enough to be adapted to other contexts. The paper begins by providing a brief review of the literature that conceptualizes the concept of hope in the field of psychology as a prelude to comparing the concept to the interdisciplinary notion of radical hope. Based on this body of work, we then introduce a culturally relevant psychological framework of radical hope, which includes the components of collective memory as well as faith and agency. Both components require an orientation to one of four directions including individual orientation, collective orientation, past orientation, and future orientation. The framework also consists of pathways individuals can follow to experience radical hope including (a) understanding the history of oppression along with the actions of resistance taken to transform these conditions, (b) embracing ancestral pride, (c) envisioning equitable possibilities, and (d) creating meaning and purpose in life by adopting an orientation to social justice. We conclude with a proposed research agenda for radical hope.     

Speaking for the baby: A therapeutic intervention with adolescent mothers and their infants

Adolescent mothers frequently experience problems in mother-infant interaction. However, intervention can be very difficult, particularly when complicated by unresolved conflicts involving relationships in the young woman's past. This article describes a therapeutic intervention, based on the work of Fraiberg, which allows the young mother to learn to interpret her infant's cues while also encouraging her to express her own emotions in the context of the mother-infant relationship. Two case studies are discussed to illustrate the use of the technique as part of a program of mother-infant intervention.     

An Investigation of Treatment Integrity and Outcomes in Wraparound Services

Research on wraparound services has been generally positive, but has failed to include data regarding treatment integrity. Without such data, conclusions drawn from such studies are weakened. This study followed 28 children and adolescents receiving wraparound services in rural central Pennsylvania. Treatment integrity was defined as the percentage of service hours prescribed vs. received, and behavioral outcomes were defined as Total Problem Behavior T Scores on the Child Behavior Checklist. Preliminary analyses failed to reveal significant differences in sample means between included subjects and those excluded due to missing data. Outcome behavior ratings were significantly improved over baseline ratings. Regression analyses, however, failed to find a significant effect for treatment integrity when used in an outcome prediction equation for Therapeutic Support Staff, Mobile Therapy services, or Behavioral Specialist wraparound services. These results suggest that adherence to prescribed treatment hours may not be related to behavioral outcomes in a wraparound service setting.     

Serial color-word test predicts outcome of pharmacological treatment for panic disorder.

A group of 50 outpatients with Panic Disorder were given the Serial Color-Word Test at the beginning of a standard pharmacological treatment (selective serotonin reuptake inhibitors and benzodiazepines). A single treating psychiatrist, blind to test results, judged therapy outcome at a 5-mo. follow-up. Among the main types of adaptation to conflict assessed by the test (Stabilized, Cumulative, Dissociative, and Cumulative-Dissociative), the Stabilized pattern predicted a good therapy outcome. Response to therapy among the patients with a Stabilized pattern was judged as more often good and less often moderate or poor, compared with the members of the other three adaptation classes (p=.004), and specifically with the patients resorting to a Cumulative strategy (p=.005).     

Dementia and working memory

This study explored the hypothesis that patients suffering from dementia of the Alzheimer type (DAT) are particularly impaired in the functioning of the Central Executive component of working memory, and that this will be reflected in the capacity of patients to perform simultaneously two concurrent tasks. DAT patients, age-matched controls and young controls were required to combine performance on a tracking task with each of three concurrent tasks, articulatory suppression, simple reaction time to a tone and auditory digit span. The difficulty of the tracking task and length of digit sequence were both adjusted so as to equate performance across the three groups when the tasks were performed alone. When digit span or concurrent RT were combined with tracking, the deterioration in performance shown by the DAT patients was particularly marked.     

Man-Machine interaction in natural language: Computational models of dialogue

This article presents a state-of-the-art review of studies on computational modeling of dialogue. Particular attention is given to the treatment of ill-formed input, the prevention of the hearer’s misconceptions, the inference of the speaker’s plans, the generation of language, and the recognition of dialogue focus—particularly in terms of implications for linguistics. Specifications and initial results of some recent studies carried out by the author are provided. This article is a revised version of a lecture held at the Third Scientific Meeting “Computer Processing of Linguistic Data,” Bled, 1985.     

A Characterization of von Neumann Games in Terms of Memory

An information completion of an extensive game is obtained by extending the information partition of every player from the set of her decision nodes to the set of all nodes. The extended partition satisfies Memory of Past Knowledge (MPK) if at any node a player remembers what she knew at earlier nodes. It is shown that MPK can be satisfied in a game if and only if the game is von Neumann (vN) and satisfies memory at decision nodes (the restriction of MPK to a player's own decision nodes). A game is vN if any two decision nodes that belong to the same information set of a player have the same number of predecessors. By providing an axiom for MPK we also obtain a syntactic characterization of the said class of vN games.
