ASSESSMENT OF STIMULUS PREFERENCE AND REINFORCER VALUE WITH PROFOUNDLY RETARDED INDIVIDUALS

We evaluated a procedure for identifying potential reinforcers with profoundly retarded individuals. In Experiment 1, six persons were repeatedly exposed to 16 stimuli, and approach behaviors to each stimulus were used to identify preferred and nonpreferred stimuli. In Experiment 2, we examined the reinforcing properties of preferred and nonpreferred stimuli by delivering them contingently on the occurrence of arbitrarily selected responses. Results revealed that the preferred stimulus conditions typically produced higher rates of responding than did either the baseline or the nonpreferred stimulus conditions, suggesting that the procedure can be used to assess reinforcer value for individuals with limited behavioral repertoires.     

Surviving death: how to refute termination theses

When deciding how ‘death’ should be defined, it is helpful to consider cases in which vital functions are restored to an organism long after those vital functions have ceased. Here I consider whether such restoration cases can be used to refute termination theses. Focusing largely on the termination thesis applied to human animals (the view that when human animals die they cease to exist), I develop a line of argument from the possibility of human restoration to the conclusion that in many actual cases, human animals continue to exist after they die. The line of reasoning developed here can be extended to show that other organisms survive death in many actual cases. This line of reasoning improves on other arguments that have been offered against termination theses. And if my argument regarding human animals surviving death is successful, then assuming that human persons are animals, we can also conclude that human persons in many actual cases continue to exist after death.     

Human and Animal Subjects of Research: The Moral Significance of Respect versus Welfare

Human beings with diminished decision-making capacities are usually thought to require greater protections from the potential harms of research than fully autonomous persons. Animal subjects of research receive lesser protections than any human beings regardless of decision-making capacity. Paradoxically, however, it is precisely animals’ lack of some characteristic human capacities that is commonly invoked to justify using them for human purposes. In other words, for humans lesser capacities correspond to greater protections but for animals the opposite is true. Without explicit justification, it is not clear why or whether this should be the case. Ethics regulations guiding human subject research include principles such as respect for persons—and related duties—that are required as a matter of justice while regulations guiding animal subject research attend only to highly circumscribed considerations of welfare. Further, the regulations guiding research on animals discount any consideration of animal welfare relative to comparable human welfare. This paper explores two of the most promising justifications for these differences␣between the two sets of regulations. The first potential justification points to lesser moral status for animals on the basis of their lesser capacities. The second potential justification relies on a claim about the permissibility of moral partiality as␣found in common morality. While neither potential justification is sufficient to justify the regulatory difference as it stands, there is possible common ground between supporters of some regulatory difference and those rejecting the current difference.     

The effect of chronic caffeine consumption on urinary incontinence in psychogeriatric inpatients

Abstract

Urinary incontinence is a common problem in psychiatric settings, particularly among psychogeriatric patients. In view of the known diuretic action of caffeine, the present study assessed the effect of tea and coffee consumption on level of incontinence in selected psychogeriatric inpatients. A total of 14 patients participated in the study which employed a combined “withdrawal” and “multiple-baseline across subjects” design to examine the effect of alternating phases of caffeine exposure and abstinence on frequency of daytime and nighttime incontinence. Incontinence levels were significantly reduced during periods of caffeine abstinence relative to periods of chronic caffeine exposure. The hypothesis that observed reductions in incontinence may have been due to accompanying reductions in fluid intake was examined but not supported.     

Indiscernible Persons

In this article I discuss identity and indiscernibility for person-stages and persons. Identity through time is not an identity relation (it is a unity relation). Identity is carefully distinguished from persistence. Identity is timeless and necessary. Person-stages are carefully distinguished from persons. Theories of personal persistence are not theories of identity for persons. I deal not with the persistence of persons through time but with the timeless and necessary identity and indiscernibility of persons. I argue that it is possible that there are non-identical but indiscernible temporally whole persons. I discuss the biographies of persons and develop the type or token distinction for persons. Twins in symmetrical or eternally recurrent universes are examples of indiscernible persons. I discuss temporal and modal branching, and I end with survival for person-tokens and eternity for person-types.     

待岗人员的应付方式、控制感特点及其关系研究

对待岗人员的应付方式和控制感进行调查发现：（1）待岗人员对待压力的应付方式依次为退避、合理化、求助、自责、发泄。女性更多地采用这五种应付方式,年龄偏大组更倾向于选择合理化和退避,30岁是应付方式发展的转折时期;（2）待岗人员的控制感由高至低依次为环境变化、人际关系、情绪情感和生活方面的控制感。女性更能控制情绪情感;（3）在待岗人员应付待岗后各种压力的情境下,可将退避归为积极的应付方式,将自责、求助、发泄归为消极的应付方式。     

“This phone saved my life”: Older persons’ experiences and appraisals of an mHealth intervention aimed at addressing loneliness

This qualitative study aimed to explore older persons’ experiences and appraisals of the utility of an mHealth intervention for reducing their sense of loneliness. Participants (n = 13; 86.42% females; age range 65 to 87 years) received training in the use of a smartphone and a social networking application (WhatsApp). Following the intervention, they completed a focus group discussion. For data triangulation, participants shared their social media postings. Content analysis of the focus group discussion and social media data indicated that the mobile device was used to mitigate perceptions of loneliness and isolation, thus facilitating social network building, enhancing self-efficacy, and improving cognitive flexibility. Mobile phones and a social networking application appear to reduce loneliness experienced by the elderly.     

Two Puzzles for Deontologists: Life-Prolonging Killings and the Moral Symmetry Between Killing and Causing a Person to be Unconscious

Some form of agent-relative constraint against the killing of innocent personsis a central principle in deontological moraltheories. In this article I make two claimsabout this constraint. First, I argue that somekillings of innocents performed incircumstances usually not taken to exculpatethe killer are not even pro tanto wrong.Second, I contend that either there is noagent-relative constraint against the killingof innocents or this constraint has a verydifferent shape from that which deontologistsnormally take it to have. My defence of theseclaims rests on two propositions. First, inkilling someone one may actually prolong thatperson's life. Roughly, life-prolongingkillings are possible, because to kill someoneis to perform an act that causes someone'sdeath and it might well be true that, had onenot performed this act, one's ``victim' wouldhave died earlier. Second, all other thingsbeing equal, killing and causing a person to beunconscious are morally equivalent. Both ofthese propositions are defended in thearticle.     

Latent class models for nonmonotone dichotomous items

Starting from perfectly discriminating nonmonotone dichotomous items, a class of probabilistic models with or without response errors and with or without intrinsically unscalable respondents is described. All these models can be understood as simply restricted latent class analysis. Thus, the estimation and identifiability of the parameters (class sizes and item latent probabilities) as well as the chi-squared goodness-of-fit tests (Pearson and likelihood-ratio) are free of the problems. The applicability of the proposed variants of latent class models is demonstrated on real attitudinal data.This research was supported by the Kulturamt der Stadt Wien, Magistratsabteilung 7.The author wishes to thank the editor, Ivo W.
