3. The Voyager and the Voyage

ABSTRACT Chapter 3 presents the biography of Dodge Morgan from childhood through the end of his remarkable voyage. Derived from biographical and autobiographical sources, his life narrative is presented chronologically as basic data for our case study. The importance of his male role models, his early love of sailing, and his later adventures on boats, in Alaska, and in the business world are illustrated. We describe the context of his voyage and his intense, thorough voyage preparations, both external and internal. We also delineate his successful circumnavigation in detail.     

4. Personality Profiles

ABSTRACT Chapter 4 discusses the origins of the Dodge Morgan case study and the circumstances of his assessments. We present findings in the contexts of both the five-factor model (FFM) and the life-story model (LSM). We interpret Personality Research Form scale scores within the five-factor structure in order to create Morgan's FFM personality profile, which is supplemented with Thematic Apperception Test (TAT) data. We structure his LSM profile from multiple evaluations, including his TAT protocol and his earliest memories; from autobiographical data, including his published writings; and from additional biographical sources. Finally, we discuss the strengths and limitations of each theory and profile construction method.     

Common reasoning about admissibility

We analyze common reasoning about admissibility in the strategic and extensive form of a game. We define a notion of sequential proper admissibility in the extensive form, and show that, in finite extensive games with perfect recall, the strategies that are consistent with common reasoning about sequential proper admissibility in the extensive form are exactly those that are consistent with common reasoning about admissibility in the strategic form representation of the game. Thus in such games the solution given by common reasoning about admissibility does not depend on how the strategic situation is represented. We further explore the links between iterated admissibility and backward and forward induction.     

The Analytic Truth and Falsity of Disjunctions

Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus.     

Performance of Faller and Nonfaller Older Adults on a Motor–Motor Interference Task

Typically, falls in older adults occur when 2 tasks are performed simultaneously, due to the increased motor demand required to maintain stability and attention to perform the other task. The authors' purpose was to investigate walking while grasping, transporting, and placing a dowel on a predetermined target while manipulating difficulty levels of the manual task. Faller and nonfaller older adults performed a walking block (manual tasks combined with gait) and a stationary block (upright stance combined with manual tasks). The manual task involved grasping, transporting, and placing the dowel over a target. The results showed that fallers underperformed when compared with nonfallers in the task of placing the dowel over the target. The main difference observed between the groups was found in the condition that required allocation of attention between tasks and greater accuracy in the final placement of the object. Fallers showed gait stability similar to the nonfallers, but fallers were less accurate than nonfallers in the object placement task, especially for the highest level of difficulty. Thus, fallers seem to use a stability-first strategy. Fallers had problems in executing the manual tasks, which suggests a more global change in motor behavior rather than specific changes to balance control.     

Internalizing and Externalizing Problem Behavior: a Test of a Latent Variable Interaction Predicting a Two-Part Growth Model of Adolescent Substance Use

Externalizing symptoms robustly predict adolescent substance use (SU); however, findings regarding internalizing symptoms have been mixed, suggesting that there may be important moderators of the relationship between internalizing problems and SU. The present study used a longitudinal community sample (N?=?387, 55% female, 83% White) to test whether externalizing symptoms moderated the relationship between internalizing symptoms and trajectories of alcohol and marijuana use from early (age 11–12 years old) to late (age 18–19 years old) adolescence. Two-part latent growth models were used to distinguish trajectories of probability of use from trajectories of amount of use among users. Results suggested that externalizing symptoms moderated the association between internalizing symptoms and probability of alcohol, but not marijuana use. The highest probability of alcohol use was observed at high levels of externalizing symptoms and low levels of internalizing symptoms. A negative protective effect of internalizing symptoms on probability of alcohol use was strongest in early adolescence for youth high on externalizing symptoms. Although moderation was not supported for amount of use among users, both domains of symptomology were associated with amount of alcohol and marijuana use as first-order effects. High levels of externalizing symptoms and low levels of internalizing symptoms were associated with high levels of amount of use among users. These findings suggest that developmental models of substance use that incorporate internalizing symptomology should consider the context of externalizing problems and distinguish probability and amount of use.     

‘Gushing Out Blood’: Defloration and Menstruation in<Emphasis Type="Italic"> Memoirs of a Woman of Pleasure</Emphasis>

John Cleland’s 1740s pornographic novel, Memoirs of a Woman of Pleasure repeatedly depicts and eroticises the act of defloration. As such it is a revealing illustration of what Ivan Bloch termed the ‘defloration mania’ of the eighteenth century. This article maps narrative events on to contemporary medical depictions of first intercourse to show the ways that the theories and ideas presented in medical and pseudo-medical texts transferred into erotic fiction and demonstrates how in some instances the bloody defloration scenes can be read as being sex during menstruation, an act which was culturally forbidden at this time.     

Mindfulness and Emotional Distress: the Mediating Role of Psychological well-Being

The present cross-sectional study aimed to clarify the relationships among specific facets of dispositional mindfulness, psychological well-being, and emotional distress. To understand the relationships among these variables is crucial in order to expand the knowledge of the processes underlying mindfulness effects and to develop effective interventions. The participants (119 Italian males and females; mean age = 29 years) completed self-report questionnaires assessing mindfulness (i.e., observing, describing, acting with awareness, non-judging of inner experience, non-reactivity to inner experience), emotional distress, and psychological well-being. Path analysis revealed that each facet of mindfulness played a unique role in influencing emotional suffering. In line with our prediction, no significant correlation emerged between the observing facet and either psychological well-being or emotional distress. Both the capacity to describe inner events and to act with awareness had an indirect effect on emotional distress, which was fully mediated by the perception of psychological well-being. On the other hand, the capacity for non-reacting to emotions and thoughts directly influenced emotional distress. Interestingly, non-judging inner events showed both a direct and indirect effect on the outcome variable. These findings confirmed the significant role of psychological well-being in mediating the relationship between some facets of mindfulness and emotional distress. Moreover, different mindfulness abilities play specific roles in reducing emotional distress, so mindfulness should be considered as a multidimensional construct.
