论伦理命题的意义

元伦理学在有意无意之间坚持了伦理命题没有“描述性”意义的教条。从“意义单位”理论出发 ,一个语言单位 (语词、语句或话语 )的意义 ,内在于它与同类单位发生联系而构成更高层次语言单位的能力 ,因此 ,一个有意义的纯伦理命题应该是一个“实质蕴涵”的复合命题 ,即“‘应该A’蕴涵‘应该B’”。     

The effects of baby bath and massage by fathers on the family system: The sunraysia australia intervention project

Instruction in baby massage and the Burleigh Relaxation Bath technique was given to one-half of our sample of 32 couples who had just had their first child. This brief intervention, given at 4 weeks post-partum, led to beneficial behavioural and psychological effects for the family system when assessed at 12 weeks postpartum. Depression and marital satisfaction were assessed with mothers and fathers at 4 weeks and 12 weeks after the birth of their child, and self-esteem was measured at 12 weeks only. The mothers and fathers who were shown baby bathing and massage techniques showed higher degrees of marital satisfaction and self-esteem, as well as lower levels of depression at 12 weeks post-partum, than parents who did not receive instruction. It seems likely that brief interventions which educate new parents concerning functional techniques of baby care may favourably affect their feelings of competence and be of benefit to the entire family system.     

HUMANITY IN THE WORLD OF LIFE

Abstract. The position and role of humanity in the world of life is examined in the light of the ontological structure of life itself. This problem is approached by considering the possible units of life representing various modes of life phenomena. I argue that the only meaningful unit of life without interposing some special external conditions is "global life" framed in a star-planet system. Any other possible unit of life exhibited by various kinds of individuals is conditional in the sense that it would leave out an essential part as "co-life." The relationship between human being and the global life should be understood in this general scheme of individual and global life. It is emphasized, however, that human being occupies a unique position in global life in the sense that humanity can promote either a cancerous situation or a healthy higher-order enhancement of the global life.     

Unit price as a useful metric in analyzing effects of reinforcer magnitude.

In this paper, we applied the behavioral-economic concept of unit price to the study of reinforcer magnitude in an attempt to provide a consistent account of the effects of reinforcer magnitude on behavior. Recent research in the experimental analysis of behavior and in behavioral pharmacology suggests that reinforcer magnitude interacts with the schedule of reinforcement to determine response rate and total consumption. The utility of the unit-price concept thus stems from its ability to quantify this interaction as a cost-benefit ratio (i.e., unit price = characteristics of the schedule of reinforcement divided by magnitude of reinforcement). Research employing the unit-price concept has shown that as unit price increases, a positively decelerating function exists for consumption (i.e., a function with an increasingly negative slope, when plotted on log coordinates) and a bitonic function exists for response rate. Based on these findings, the present analysis applied the unit-price concept to those studies of reinforcer magnitude and drug self-administration that examined the effects of reinforcer magnitude on response rate using simple schedules of reinforcement (e.g., fixed-ratio schedule). This resulted in three findings: (a) Reinforcer-magnitude manipulations and schedule manipulations interact in a manner that can be quantified in terms of unit price as benefit and cost factors, respectively; (b) different reinforcer-magnitude manipulations are functionally interchangeable as benefit factors in the unit-price ratio; and (c) these conclusions appear warranted despite the differences in reinforcers (food or drug), species (dogs, monkeys, or rats), and schedules (interval or ratio), and despite the fact that these studies were not designed for a unit-price analysis. In methodological terms, these results provide further evidence that employing the unit-price concept is a parsimonious method for examining the effects of reinforcer magnitude. In theoretical terms, these results suggest that a single process may underlie the effect of combined reinforcer-magnitude and schedule manipulations.     

Melodies in caregivers' speech: A species-specific guidance towards language

The author reports on a series of integrated studies on melodic contours in infant-directed (ID) speech. ID melodies in speech are taken as an instructive example of intuitive parenting in order to review current evidence on its forms, functions and determinants. The forms and functions of melodic prototypes are compared in terms of universal properties and individual and/or cultural variability across samples of German, Chinese and American mothers, and German mothers and fathers with their 2- and 3-month-old infants. Microanalyses of interactional contexts show that forms and functions of ID melodies are intimately related to typical dimensions of intuitive caregiving–arousing/soothing, turnyielding/turn-closing, approving/disapproving. The communicative functions of ID melodies as both categorical and graded signals are discussed with respect to the current knowledge on infant responses to ID speech and on early speech perception. According to a comprehensive longitudinal study of ID speech in relation to stages of infant vocalization, ID speech results from fine-tuned adjustments in various prosodic and linguistic features to developmental changes in infants' perceptual and vocal competence. ID melodies evidently have the potential to draw infant attention to caregivers' speech, to regulate arousal and affect in infants, to provide models for imitation, to guide infants in practising communicative subroutines and to mediate linguistic information. Current evidence suggests that the melodies in caregivers' speech provide a species-specific guidance towards language acquisition.     

Behavioral economics of drug self-administration. II. A unit-price analysis of cigarette smoking.

In behavioral economics, the ratio of response requirement to reinforcer magnitude is referred to as unit price. Previous research with nonhuman subjects has demonstrated that (a) comparable amounts of food are consumed at the same unit price even though different response requirements and reinforcer magnitudes comprise that unit price and (b) increases in unit price decrease food consumption in a positively decelerating fashion. The present study assessed the generality of these findings to the cigarette smoking of 5 human volunteers. During approximately 18 3-hr sessions, various combinations of response requirement (fixed-ratio 200, 400, and 1,600) and reinforcer magnitude (1, 2, and 4 puffs per bout) were arranged. Consumption (i.e., the number of puffs) generally was comparable at the same unit price independent of the response requirement and reinforcer magnitude comprising that unit price. In addition, increasing unit price generally decreased consumption in a positively decelerating fashion. These results extend the generality of the unit-price analysis to human cigarette smoking. Moreover, these results further support the position that reinforcer magnitude and response requirement are functionally equivalent and interact to determine consumption. The concept of unit price, by integrating and summarizing the effects of those two operations, provides a more parsimonious explanation of the results than do separate evaluations of the effects of response requirement and reinforcer magnitude.     

Assessing the impact of a family nurse-led intervention on young mothers’ references to internal states

A mother's propensity to refer to internal states during mother–child interactions is important for her child's developing social understanding. However, adolescent mothers are less likely to reference internal states when interacting with their children. We investigated whether young mothers’ references to internal states are promoted by the Family Nurse Partnership (FNP) intervention, an intensive home-visiting programme designed to support adolescent mothers in England. We also investigated family, maternal, and child factors associated with young mothers’ references to inner states during interactions with their children. Adolescent mothers (n = 483, aged ≤ 19 years when recruited in pregnancy) and their children participated in an observational substudy of a randomized controlled trial investigating the impact of FNP compared to usual care. Mother–child dyads were video-recorded during free play, and mothers’ speech was coded for use of internal state language (references to cognitions, desires, emotions, intentions, preferences, physiology, and perception). We found no differences in mothers’ use of internal state language between the FNP and usual care groups. A sample-wide investigation identified that other features of mothers’ language and relationship status with the child's father were associated with internal state language use. Findings are discussed with reference to targeted interventions and implications for future research.

MORPHINE TOLERANCE AS A FUNCTION OF RATIO SCHEDULE: RESPONSE REQUIREMENT OR UNIT PRICE?

Key pecking by 3 pigeons was maintained by a multiple fixed-ratio 10, fixed-ratio 30, fixed-ratio 90 schedule of food presentation. Components differed with respect to amount of reinforcement, such that the unit price was 10 responses per 1-s access to food. Acute administration of morphine, l-methadone, and cocaine dose-dependently decreased overall response rates in each of the components. When a rate decreasing dose of morphine was administered daily, tolerance, as measured by an increase in the dose that reduced response rates to 50% of control (i.e., the ED50 value), developed in each of the components; however, the degree of tolerance was smallest in the fixed-ratio 90 component (i.e., the ED50 value increased the least). When the l-methadone dose-effect curve was redetermined during the chronic morphine phase, the degree of cross-tolerance conferred to l-methadone was similar across components, suggesting that behavioral variables may not influence the degree of cross-tolerance between opioids. During the chronic phase, the cocaine dose-effect curve shifted to the right for 2 pigeons and to the left for 1 pigeon, which is consistent with predictions based on the lack of pharmacological similarity between morphine and cocaine. When the morphine, l-methadone, and cocaine dose-effect curves were redetermined after chronic morphine administration ended, the morphine and l-methadone ED50s replicated those obtained prior to chronic morphine administration. The morphine data suggest that the fixed-ratio value (i.e., the absolute output) determines the degree of tolerance and not the unit price.
