Structure-Making

Friends of states of affairs and structural universals appeal to a relation, structure-making, that is allegedly a kind of composition relation: structure-making ‘builds’ facts out of particulars and universals, and ‘builds’ structural universals out of unstructured universals. D. M. Armstrong, an eminent champion of structures, endorses two interesting theses concerning composition. First, that structure-making is a composition relation. Second, that it is not the only (fundamental) composition relation: Armstrong also believes in a mode of composition that he calls mereological, and which he takes to be the only kind of composition recognized by his philosophical adversaries, such as David Lewis. Armstrong, accordingly, is a kind of pluralist about compositional relations: there is more than one way to make wholes from parts. In this paper, I critically evaluate Armstrong's compositional pluralism.     

Pain and Play: Building Coalitions toward Decolonizing Philosophy

In what follows I offer three theoretical frameworks out of which we might think through coalition building for the sake of decolonization. My claim is that, through these three frameworks, we can be attentive to the ways we, ourselves are shaped by coloniality as we collectively work to resist it. The first framework is Maria Lugones's account of playful world‐travel. The second concerns the practice of unsuturing, developed George Yancy. And the third is Édouard Glissant's notion of opacity (as that conception pertains to his account of errantry). In bringing these together, I foreground opacity as the cornerstone of an encounter between self and Other, as that encounter figures both in Lugones's account of world traveling, and in Glissant's account of errantry. I use George Yancy's conception of unsuturing to show that it is more productive to think of world‐travel's play as coupled with unsuturing's pain, rather than to think of these comportments as either mutually exclusive or diametrically opposed. Lugones, Glissant, and Yancy show that, out of this pain‐play comportment, our collective commitments to decolonization might result in more effective coalitions against the workings of colonial power, so as to gesture toward the possibility of alternative (decolonial) worlds.     

Dynamic, state-dependent thresholds for the perception of single-element apparent motion: Bistability from local cooperativity

Previous studies have indicated that the formation of coherent patterns for multielement motion displays depends onglobal cooperative interactions among large ensembles of spatially distributed motion detectors. These interactions enhance certain motion directions and suppress others. It is reported here that perceiving one element moving between two nearby locations likewise is subject to cooperative influences (possibly facilitating and inhibiting interactions within alocal ensemble of overlapping detectors). Thresholds depending on luminance contrast were measured for a generalized singleelement apparent-motion stimulus, and evidence for spontaneous switching and hysteresis effects indicated that motion perception near the 50% threshold was bistable. That is, for conditions in which motion and nonmotion were perceived half the time, the two percepts were distinct; when one was perceived, it clearly was discriminable from the other. These results indicated that (1) single-element apparent-motion thresholds depended on the immediately preceding state of the ensemble of motion detectors responding to the stimulus, and (2) the stimulus activation of individual motion detectors always might be influenced by recurrent, cooperative interactions resulting from the detectors’ being embedded within interconnected ensembles.     

Lexical Acquisition in Probable Alzheimer''s Disease

Patients with probable Alzheimer's disease (pAD) were exposed to a new verb in a naturalistic fashion. We probed their knowledge of the word's semantic and grammatical characteristics for several minutes following this exposure, and compared this with their performance on parallel measures assessing known words. Significant differences were seen between pAD patients and controls in the acquisition of the new verb's semantic meaning and its argument structure, but pAD patients did not differ from controls in the acquisition of the new word's grammatical form class. Individual patient analyses demonstrated parallel deficits restricted to the semantic meaning and argument structure of the new word and known words in several pAD patients, suggesting that a selective language impairment contributed to their word learning deficit. This pattern is consistent with an intimate relationship between semantic meaning and argument structure in semantic memory. Other pAD patients had difficulty learning about all aspects of the new word, despite good performance with known words, suggesting that compromised memory may have limited their lexical acquisition.     

Single parenting: Interventions in the transitional stage

Following divorce or separation, many mother-headed families need to mourn losses, including reduced economic resources. They need to reestablish family rituals, confront such issues as time management and structural changes that can result in scapegoating or over-reliance on a parental child. Normalizing difficulties associated with parenting is important because single parents tend to internalize societal attribution of family difficulties to inadequate family structure rather than developmental stages, limited economic resources, and negative expectations about the capacity of women to head families.     

Time out from Stress: Camp Program and Parenting Groups for Homeless Mothers

This paper describes a camp program for homeless families and parenting groups aimed at discussing issues related to parenting while homeless. In groups and individual interviews, the women shared stories about multiple problems that negatively impacted parent/child relationships and their ability to maintain employment and residential stability. These problems included domestic violence, sexual abuse, and substance abuse. Evaluation of the camp program indicated that services available in the community and those provided by shelters were limited and mothers often had difficulties utilizing services.     

TREATMENT OF PICA THROUGH MULTIPLE ANALYSES OF ITS REINFORCING FUNCTIONS

We conducted functional analyses of the pica of 3 participants. The pica of 1 participant appeared to be maintained by automatic reinforcement; that of the other 2 participants appeared to be multiply controlled by social and automatic reinforcement. Subsequent preference and treatment analyses were used to identify stimuli that would compete with the automatic function of pica for the 3 participants. These analyses also identified the specific aspect of oral stimulation that served as automatic reinforcement for 2 of the participants. In addition, functional analysis-based treatments were used to address the socially motivated components of 2 of the participants' pica. Results are discussed in terms of (a) the importance of using the results of functional analyses to develop treatments for pica and (b) the advantages of developing indirect analyses to identify specific sources of reinforcement for automatically reinforced behavior.     

Information technology in municipal environmental policy: Automated registration,sure, but what about expert systems?

Dutch municipalities are confronted with an increased number of prescribed environmental tasks and also with a growing demand, both from the central government and environmental pressure groups, to undertake environmental activities on their own initiative. This development over-taxed the information management of most municipalities. In the past few years, computer technology was introduced to relieve part of this pressure (e.g., by automation of registration systems). In this article we present a classification of computer applications for environmental management, investigate their possible impact on the environmental knowledge and information system, and distinguish between a formal and informal knowledge domain. Special attention will be paid to expert systems.
