Human body buoyancy: a study of 98 men

The specific gravity and buoyancy of 98 men were calculated at various lung volumes. The data indicated that all subjects would be capable of floating in either freshwater or seawater at total lung capacity. At functional residual capacity, the value approximating the lung volume of a recently dead body, 69% of the subjects would float in seawater, whereas only 7% would float in freshwater. Results of this study indicate that while drowned bodies are more likely to sink than bodies dead of other causes, no conclusion regarding the cause of death can be made on the basis of whether bodies float or sink.     

The Prime Minister's mailbag

Abstract. This study is based on examination of a randomly selected sample of 2,150 letters representing all the mail received by Prime Minister Trudeau between February 1969 and June 1972. The object of the study was to ascertain the characteristics of the letter-writers and the nature of their concerns, arguments and strategies. Through interviews with the staff of the Correspondence Section of the Prime Minister's Office we were also able to discover how the mail is processed. This is described in the last section of our paper. As one might expect, the mail is unrepresentative of the regional, linguistic and class diversity of Canada. Metropolitan areas, rich provinces and English-speakers are over-represented, as are people who have access to typewriters. There is, however, a sizable group of letters from the very poor who write the Prime Minister to complain of their victimization by government bureaucracy or by life in general. These letters are personal and apolitical and approach the Prime Minister in a deferential manner. They appear to us to be carefully and sympathetically answered, and to be probably effective in rectifying small problems. The bulk of the mail is policy-oriented, but probably not effective in influencing policy. Public attention to policy, as expressed in the mail, is extremely transitory and focuses particularly on topics with strong emotional content or on those affecting economic welfare. The mail seems only weakly related to the government's own policy priorities. Sommaire. Cette étude est fondée sur un échantillon de 2,150 lettres tirées du courrier par le premier ministre Trudeau entire février 1969 et juin 1972. Nous avons voulu identifier les catégories de personnes qui s'adressaient au premier ministre, et déterminer le but de leur correspondence et la nature de leur argumentation etc. Nous avons interviewé le personnel de la section de la correspondance du cabinet du premier ministre pour connaître la procédure de réponse à ce courrier. Nous avons constaté que le courrier n'est pas représentatif de la diversité régionale, culturelle et sociale du pays. Les plus fortunés, les habitants des grandes villes, et les habitants des provinces sont surreprésentés. II y a, cependant, une proportion assez élevée de lettres venant d'économiquement faibles qui se plaignent au premier ministre de leur traitement par la bureaucratic ou de la vie en générate. Leurs problèmes sont formulés en termes personnels, et ces personnes s'adressent au premier ministre respectueusement. Les réponses à ces lettres nous paraissent sympathiques et souvent efficacies quant au redressement des plaintes. Le gros du courrier concerne l'orientation de la politique mais son influence est sans doute limitée. L'attention du public à l'égard de la politique gouvernementale est conditionnée par les évènements, en particulier les évènements à contenu émotif ou ceux qui touchent de près le bien-être des correspondants. Ce courrier ne se réfère que très indirectement aux priorités politiques du gouveniement.     

Verbal and Physical Abuse Toward Mothers: The Role of Family Configuration,Environment, and Coping Strategies

This paper focuses on parental maltreatment, a rarely documented phenomenon. We prospectively examine factors that can increase the risk of abusive behavior toward mothers. The purpose of this study is to examine the relationship between a stressful family situation, parental divorce, and verbal and physical aggression toward mothers. We use a large Canadian sample of adolescents who have been followed since kindergarten. At age 15, we assessed verbal and physical abuse toward mothers, as reported by both mothers and their adolescents. Multinomial logit modeling revealed that parental divorce was associated with a greater risk of physical aggression directed toward mothers by adolescents. Family environment and parental coping strategies partially mediated that relationship. Mothers who divorced, and remained divorced, were at greater risk of being assaulted by their adolescent children. A positive family environment, reflecting a better parent–child relationship, partially diminished this risk. However, support-seeking behavior on the part of mothers increased the risk of abuse, concurrent with tyrannical strategies often mobilized by abusive children.     

When Does Deliberation Begin? Internal Reflection versus Public Discussion in Deliberative Democracy

Political deliberation involves both internal reflection and public discussion. The former might be far more important than implied by deliberative democrats' heavy emphasis on the discursive component. Analysis of the deliberations of a citizen's jury on an Australian environmental issue shows jurors' attitudes changing more in response to the 'information' phase of the jury proceedings, involving a large degree of 'deliberation within', than during the formal 'discussion' phase. Various ways can be imagined for evoking internal reflection of that sort, even in mass-political settings.
