Historical and political interpretations of jurisprudence and the social action perspective in sociology

It is argued that a full comprehension of classical and contemporary manifestations of the “social action perspective” in sociology will be significantly facilitated by placing it within the context of jurisprudential theory, especially the theory of legal actors. The Weberian and Parsonian views of social action theory are outlined in some detail, and these positions are related as a whole to the concept of legal action in late-nineteenth-century German jurisprudence. Having established structural similarities between the two perspectives, an historical argument is developed within which it is asserted that: (a) Among the academic disciplines of late-nineteenth- and early-twentieth-century Germany, jurisprudence held a relative autonomy derived from ideological circumstances which may ultimately be traced to the political economy of the nascent German state. (b) Given such an autonomy, jurisprudence provided a paradigm for the sociocultural sciences. Each of these contentions is phrased within the intellectual milieu of the day which included both Kantian and Hegelian currents. (c) Finally, certain implications are drawn from the foregoing analysis concerning ideology and contemporary social action theory, the sociology of law, and the need for future research on the relationships between jurisprudential and other forms of social theory.     

Interspecific aggression and reactivity in rats: Effects of selective raphe lesions and additional olfactory bulb ablation

Large depletion of brain 5 HT has been shown to induce mouse-killing behavior in the rat. Selective lesions of the raphe nuclei have been investigated in order to determine whether the various components of the 5 HT system exert some specific control over this aggressive behavior. Electrolytic lesions of the dorsal or the median raphe nucleus do not induce mouse killing, whereas combined lesions of these nuclei elicit this behavior in about 40% of naive rats. Consequently, it appears that serotonergic neurons originating in the dorsal and median raphe nuclei work synergistically in mediating inhibitory control over mouse-killing behavior. Loco-motor activity is increased in novel environments by each of the selective lesions and to a larger extent by combined raphe lesions; 24 hours activity in resting conditions is unchanged during the light period, and increased during the dark period of the daily cycle by the various lesions. As it has been shown previously that hyper-activity in response to novelty following raphe lesions is not directly related to the 5 HT decrease in the brain, it appears that interspecific aggression and motor responsiveness must not be dependent on the same neural substrate within the raphe nuclei. The raphe lesions do not facilitate the elicitation of mouse killing by further olfactory bulb ablations, in contrast to earlier results where bulbectomy facilitated the induction of this behavior by raphe lesions.     

The beginning of conversation: Early patterns of mother-infant vocal responsiveness

Microanalytic techniques were used to characterize the structure of the prespeech communication of 4-month-old infants and their mothers. Two observers continuously recorded the interactive behavior of mothers and their infants during hour-long observations in the homes of 25 families. Loglinear models were used to examine the extent to which the vocal behavior of one person was conditional upon the vocal behavior of the partner. Within the limits of this microanalytic approach, analyses indicated that patterns of mother-infant vocal exchange were structurally similar to patterns of adult conversation. Initial vocal responses were followed by suppression of vocalization, allowing the partner to join the conversation. The comparative effectiveness of vocal behavior as an elicitor of vocalization and as a response to vocalization was shown for mothers and infants relative to the other behaviors observed. Vocalization served as a modulator of visual attentiveness: When the partner was not visually attentive, vocalization elicited visual attention.
