Desire satisfaction,death, and time

Desire satisfaction theories of well-being and deprivationism about the badness of death face similar problems: desire satisfaction theories have trouble locating the time when the satisfaction of a future or past-directed desire benefits a person; deprivationism has trouble locating a time when death is bad for a person. I argue that desire satisfaction theorists and deprivation theorists can address their respective timing problems by accepting fusionism, the view that some events benefit or harm individuals only at fusions of moments in time. Fusionism improves on existing solutions to the timing problem for deprivationism because it locates death’s badness at the same time as both the victim of death and death itself, and it accounts for all of the ways that death is bad for a person. Fusionism improves on existing solutions to the problem of temporally locating the benefit of future and past-directed desires because it respects several attractive principles, including the view that the intrinsic value of a time for someone is determined solely by states of affairs that obtain at that time and the view that intrinsically beneficial events benefit a person when they occur.     

Categoricalism,dispositionalism, and the epistemology of properties

Notoriously, the dispositional view of natural properties is thought to face a number of regress problems, one of which points to an epistemological worry. In this paper, I argue that the rival categorical view is also susceptible to the same kind of regress problem. This problem can be overcome, most plausibly, with the development of a structuralist epistemology. After identifying problems faced by alternative solutions, I sketch the main features of this structuralist epistemological approach, referring to graph-theoretic modelling in the process. Given that both the categoricalists and dispositionalists are under pressure to adopt this same epistemological approach in light of the regress problem, this suggests that the categoricalist versus dispositionalist debate is best fought on metaphysical rather than epistemological grounds.     

“Yes,I Can,I Feel Good,and I Just Do It!” On Gain Cycles and Spirals of Efficacy Beliefs,Affect, and Engagement

Taking Bandura's Social Cognitive Theory as our starting point, we tested how efficacy beliefs (self‐efficacy and perceived collective efficacy) reciprocally influence activity engagement (vigor, dedication, and absorption) indirectly through their impact on positive affect (enthusiasm, satisfaction, and comfort) over time. We conducted two longitudinal studies using independent samples. Study 1 is a two‐wave longitudinal field study that examines gain cycles regarding the dynamic relationships among self‐efficacy, positive affect, and work engagement in 274 secondary school teachers. Study 2 is a three‐wave longitudinal laboratory study about gain spirals in the dynamic relationships among collective efficacy beliefs, positive affect, and task engagement in 100 university students working in groups. Our findings show that: (1) efficacy beliefs reciprocally influence activity engagement indirectly through their impact on positive affect over time; (2) enthusiasm is the positive affect with the strongest effect on activity engagement; and (3) a gain spiral exists whereby efficacy beliefs increase over time due to engagement and positive affect (most notably enthusiasm). Finally, we discuss the theoretical and practical implications in terms of Social Cognitive Theory.     

Hairdressers as caregivers. I. A descriptive profile of interpersonal help-giving involvements

The interpersonal help-giving behaviors of 90 hairdressers were explored in depth in an interview study. On the average, hairdressers saw 55 customers a week, and talked 25 minutes with each. About one-third of the talking time concerned clients' moderate to serious personal problems--particularly problems with children, physical health, marriage, depression, and anxiety. Hairdressers reported that offering sympathy and support, being lighthearted, just listening, and presenting alternatives were among their most frequent response strategies. Although they often enjoyed fielding clients' personal problems, at times they felt perplexed by them. Hairdressers perceived listening to customers' interpersonal problems to be an important part of their everyday function and expressed a need for professional inputs in that domain.     

Self-reported problems: a comparison between PTSD-diagnosed veterans,their spouses,and clinicians

This study investigated self-reported problems in a sample of help-seeking Vietnam veterans, comparing the veteran's own view with clinician and spouse perspectives, with the aim of examining convergence in reports across different informants. Veterans with PTSD (N = 459) were asked to list and rate their five most serious problems. Spouses and treating clinicians completed the same questionnaire in relation to the veteran. Rates of endorsement for each problem area, and levels of agreement between raters, were calculated. Veterans, spouses, and clinicians were all likely to rate anger as a high priority, with veterans also likely to nominate anxiety and depression. Spouses were likely to nominate more observable behavioural problems such as interpersonal difficulties and avoidance, while clinicians were likely to nominate indications of psychopathology, such as anxiety, depression, and intrusive thoughts. Agreement across raters was generally high, although interpretation of agreement levels was complex.     

I OUGHT,THEREFORE I CAN

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.     

Grouping, chunking, memory, and learning

An example of grouping is dividing a long series of digits into two or more smaller units by, for example, pausing for a short time between items within groups but for a longer time between groups. Grouping, virtually neglected in animal learning, was examined in each of five rat investigations reported here in which a series of two or more runway trials was either grouped together with or apart from a terminal large reward trial. It was found that running speed on early small reward trials in the series was greater when prior trials were grouped together with rather than apart from the terminal large reward trial and this when the intertrial interval was short, 20 sec, or long, 20 to 40 min. Three possible explanations of the present findings were examined: a reward schedule view, a rule-learning view, and an anticipation view based on memory. The most feasible of these explanations, it was suggested, was the anticipation view. According to this view, when prior trials are grouped together with a terminal large reward, there is a tendency for the rat to anticipate the terminal large reward well before its scheduled occurrence, elevating running speed on earlier small reward trials. Such anticipation occurs, it was suggested, because when trials are grouped together the memory of each reward event in the series is retrieved on each subsequent trial, including the remote terminal large reward trial, where it becomes a signal for large reward. Thus the present results implicate not merely adjacent associations—associations between adjacent events—but also the highly controversial remote associations—associations between two events separated not only in time but by one or more intervening events as well.     

When fast logic meets slow belief: Evidence for a parallel-processing model of belief bias

Two experiments pitted the default-interventionist account of belief bias against a parallel-processing model. According to the former, belief bias occurs because a fast, belief-based evaluation of the conclusion pre-empts a working-memory demanding logical analysis. In contrast, according to the latter both belief-based and logic-based responding occur in parallel. Participants were given deductive reasoning problems of variable complexity and instructed to decide whether the conclusion was valid on half the trials or to decide whether the conclusion was believable on the other half. When belief and logic conflict, the default-interventionist view predicts that it should take less time to respond on the basis of belief than logic, and that the believability of a conclusion should interfere with judgments of validity, but not the reverse. The parallel-processing view predicts that beliefs should interfere with logic judgments only if the processing required to evaluate the logical structure exceeds that required to evaluate the knowledge necessary to make a belief-based judgment, and vice versa otherwise. Consistent with this latter view, for the simplest reasoning problems (modus ponens), judgments of belief resulted in lower accuracy than judgments of validity, and believability interfered more with judgments of validity than the converse. For problems of moderate complexity (modus tollens and single-model syllogisms), the interference was symmetrical, in that validity interfered with belief judgments to the same degree that believability interfered with validity judgments. For the most complex (three-term multiple-model syllogisms), conclusion believability interfered more with judgments of validity than vice versa, in spite of the significant interference from conclusion validity on judgments of belief.     

Age-related increases in the effects of automatic semantic activation.

Automatic semantic activation was assessed in a version of the flanker task, in which nominally irrelevant words were presented above and below a target word. The category membership of the flanking word was consistent, inconsistent, or neutral with respect to the target word. Older adults showed greater inhibition and equivalent facilitation in the time taken to classify the target words than did younger adults in 2 of 3 experiments, in contrast to previous findings. The present results are generally consistent with 3 dominant perspectives in cognitive aging: the complexity hypothesis, environmental support, and the inhibition-deficit view. Manipulation of the overall magnitude of the flanker effect produced results most consistent with the inhibition-deficit view that older adults are less able to inhibit automatic processes than are younger adults. Some problems with the inhibition-deficit view are also discussed.     

The reflexive loop of past, present, and future in systemic therapy and consultation.

Time is one of the most basic social constructions. There are several different "times" (individual, social, cultural). This article deals with the time variable in systemic therapy--a most important variable, but often underestimated by therapists--and seeks to illustrate, with clinical examples, the peculiar interplay of past, present, and future in the therapy session. The co-creation of the past and future in the therapeutic system is also considered, together with the different temporal horizons of the family therapist and the observation team. In our view, time is one of the key issues in successful therapy: consideration of time can open new perspectives in both therapy and research.     

Philosophy, Solipsism and Thought

Wittgenstein's view of philosophy in the Tractatus presupposes that thought may be revealed without remainder in the use of signs. It is commonly held, however, that in the Tractatus he treated thought as logically prior to language. If this view, expressed most lucidly by Norman Malcolm, were correct, Wittgenstein would be inconsistent in holding that thought can be revealed without remainder in the use of signs. I argue that this is not correct. Thought may be prior to language in time but not in logic , for non-verbal symbols must have a logical structure in common with verbal ones. A view comparable with Malcolm's holds that Wittgenstein, under the influence of Schopenhauer, is committed to some form of solipsism. I argue that neither Schopenhauer nor Wittgenstein held any version of solipsism. For both philosophers, subject and object are correlative, so that it is incoherent to affirm the existence of the one without presupposing the existence of the other.     

Temporal Externalsm,Natural Kind Terms,and Scientifically Ignorant Communities

Abstract

Temporal externalism (TE) is the thesis (defended by Jackman (1999)) that the contents of some of an indvidual's thoughts and utterances at time t may be determined by linguistic developments subsequent to t. TE has received little discussion so far, Brown (2000) and Stoneham (2002) being exceptions. I defend TE by arguing that it solves several related problems concerning the extension of natural kind terms in scientifically ignorant communities. Gary Ebbs (2000) argues that no theory can reconcile our ordinary, practical judgments of sameness of extension over time with the claim that linguistic usage determines word extensions. I argue that Ebbs shows at most that no theory other than TE can effect this reconciliation. Furthermore, while Ebbs' argument undermines Jessica Brown's solutions to two closely related problems about natural kind term extensions (Brown 1998), TE can solve both problems without difficulty. Some criticisms of TE are briefly addressed as well.     

A REAPPRAISAL OF LEIBNIZ'S VIEWS ON SPACE, TIME, AND MOTION

Leibniz has been widely praised for maintaining against the Newtonians of his day the view that space and time are relative. At the same time, he has been roundly criticized for allowing that we can distinguish absolute from merely relative motion. This distribution of applause and criticism, I will argue, is in a measure unjustified. For on the one hand, those arguments, found in his correspondence with Clarke, by which Leibniz seeks to reject the view that space and time are "something absolute" are for the most part unsatisfactory, and on the other hand, Leibniz was not so naive as his critics have supposed in allowing absolute motions. Sections I - V of this essay will be concerned with the former issue; Leibniz's views on motion will be taken up in Section VI. The chief interest in all of this for present-day philosophers may lie, not so much in the historical issues concerning Leibniz and the Newtonians, but in a meta-philosophical question which inevitably arises from the historical issues, namely, the question whether developments in science can undermine the soundness of philosophical arguments which appeal to ordinary usage.     

Knowledge,Safety, and Meta‐Epistemic Belief

This article raises problems both for the view that safe belief is necessary for knowledge and for the view that it is sufficient. Focusing on ‘meta‐epistemic beliefs,’ or beliefs about the epistemic status of one's own beliefs, it is shown that the necessity claim has counterintuitive implications and that the sufficiency claim implies a contradiction. It is then shown that meta‐epistemic beliefs raise similar problems for a wide range of accounts of knowledge, and hence that they provide a powerful test for theories of knowledge.     

Surrogate‐assisted multicriteria optimization: Complexities,prospective solutions,and business case

Complexity in solving real‐world multicriteria optimization problems often stems from the fact that complex, expensive, and/or time‐consuming simulation tools or physical experiments are used to evaluate solutions to a problem. In such settings, it is common to use efficient computational models, often known as surrogates or metamodels, to approximate the outcome (objective or constraint function value) of a simulation or physical experiment. The presence of multiple objective functions poses an additional layer of complexity for surrogate‐assisted optimization. For example, complexities may relate to the appropriate selection of metamodels for the individual objective functions, extensive training time of surrogate models, or the optimal use of many‐core computers to approximate efficiently multiple objectives simultaneously. Thinking out of the box, complexity can also be shifted from approximating the individual objective functions to approximating the entire Pareto front. This leads to further complexities, namely, how to validate statistically and apply the techniques developed to real‐world problems. In this paper, we discuss emerging complexity‐related topics in surrogate‐assisted multicriteria optimization that may not be prevalent in nonsurrogate‐assisted single‐objective optimization. These complexities are motivated using several real‐world problems in which the authors were involved. We then discuss several promising future research directions and prospective solutions to tackle emerging complexities in surrogate‐assisted multicriteria optimization. Finally, we provide insights from an industrial point of view into how surrogate‐assisted multicriteria optimization techniques can be developed and applied within a collaborative business environment to tackle real‐world problems.     

Compliance,opposition, and behavior problems in toddlers born preterm or low birthweight

Although children born preterm or low birth weight (PT LBW) are more likely to exhibit behavior problems compared to children born at term, developmental and family processes associated with these problems are unclear. We examined trajectories of maternal depressive symptoms in relation to toddler compliance and behavior problems in families with PT LBW infants. A total of 177 infants (93 boys, 84 girls) and their mothers enrolled in the study during the infant's NICU stay. Data were collected at five time points across 2 years. Assessments of maternal depressive symptoms were conducted at all time points, and toddler compliance and opposition to maternal requests and behavior problems were assessed at 2 years. Toddlers born earlier with more health problems to mothers whose depressive symptoms increased over time exhibited the most opposition to maternal requests during a cleanup task at 24 months, consistent with multiple risk models. Mothers with elevated depression symptoms reported more behavior problems in their toddlers. The study has implications for family‐based early intervention programs seeking to identify PT LBW infants at highest risk for problem behaviors.     

Kant,Boole and Peirce's Early Metaphysics

Charles Peirce is often credited for being among the first, perhaps even the first, to develop a scientific metaphysics of indeterminism. After rejecting the received view that Peirce developed his views from Darwin and Maxwell, I argue that Peirce's view results from his synthesis of Immanuel Kant's critical philosophy and George Boole's contributions to formal logic. Specifically, I claim that Kant's conception of the laws of logic as the basis for his architectonic, when combined with Boole's view of probability, yields Peirce's metaphysics of probabilistic laws. Indeterminism provides, therefore, an excellent illustration of how Peirce attempted to use logic to clarify metaphysical problems.Since everyone must have conceptions of things in general, it is most important that they should be carefully constructed. I shall enter into no criticism of the different methods of metaphysical research, but shall merely say that in the opinions of several great thinkers, the only successful mode yet lighted upon is that of adopting our logic as our metaphysics.

Adolescent pregnancy: contributing factors, consequences, treatment, and plausible solutions

Adolescence, although not always necessarily a period of extreme stress, is a time of profound physical changes which increase the adolescent's awareness of and interest in sexual behavior. This issue of sexuality, which begins in early adolescence, creates new challenges to personal and gender identity formation as the person matures. Sexual maturation is a three-fold process, requiring growth in understanding of oneself as a sexual being, in the ability to handle interpersonal relationships effectively, and in the capacity to plan behavior in view of future outcomes and present problems. A current concern is that today's adolescents, including early adolescents, may be making important life choices such as parenthood before they are developmentally ready for such roles (Chilman, 1980). This paper deals with pregnancy in adolescents and modes of responding to this phenomenon by those in the counseling and other helping professions.
