The Making of Female Presidents and Prime Ministers: The Impact of Birth Order, Sex, of Siblings, and Father-Daughter Dynamics

Although research into the factors that may affect male achievement of political leadership is relatively robust, very few studies on the making of female presidents and prime ministers exist. This paper examines the literature on birth order, sex of siblings, and parent-daughter dynamics to see whether the findings for male political leaders—that first-born individuals will be overrepresented as compared with later-born siblings—also hold for female ones. Two other hypotheses were tested concerning differences in birth order and sex of siblings between female political leaders and a larger sample of women. A review of the literature on parent-daughter dynamics suggests that this may be another important variable for future research into explanations for the success of women who achieve senior-level positions of power. The findings suggest that first-born women, like first-born men, are overrepresented among political leaders; that first-born women are overrepresented among female political leaders as compared with their numbers in a larger sample population; and that fewer female political leaders have an older brother than would be expected to occur in a larger sample population. The last finding applies only for women who come to power in the period 1960–1989, not those who gained office more recently.     

Critical thinking in North America: A new theory of knowledge,learning, and literacy

The pace of change in the world is accelerating, yet educational institutions have not kept pace. Indeed, schools have historically been the most static of social institutions, uncritically passing down from generation to generation outmoded didactic, lecture-and-drill-based, models of instruction. Predictable results follow. Students, on the whole, do not learn how to work by, or think for, themselves. They do not learn how to gather, analyze, synthesize and assess information. They do not learn how to analyze the diverse logic of the questions and problems they face and hence how to adjust their thinking to those problems. They do not learn how to enter sympathetically into the thinking of others, nor how to deal rationally with conflicting points of view. They do not learn to become critical readers, writers, speakers and listeners. They do not learn how to use their native languages clearly, precisely, or persuasively. They do not, therefore, become literate, in the proper sense of the word. Neither do they gain much in the way of genuine knowledge since, for the most part, they could not explain the basis for what they believe. They would be hard pressed to explain, for example, which of their beliefs were based on rational assent and which on simple conformity to what they have been told. They have little sense as to how they might critically analyze their own experience, or identify national or group bias in their own thinking. They are much more apt to learn on the basis of irrational than rational modes of thought. They lack the traits of mind of a genuinely educated person: intellectual humility, courage, integrity, perseverance, and faith in reason.Happily, there is a movement in education today striving to address these problems in a global way, with strategies and materials for the modification of instruction at all levels of education. At its foundation is an emerging new theory of knowledge, learning, and literacy, one which recognizes the centrality of independent critical thinking to all substantial learning, one which recognizes that higher-order, multilogical thinking is as important to childhood as to adult learning, and as important to foundational learning in monological as in multilogical disciplines. This educational reform movement is not proposing an educational miracle cure, for its leading proponents recognize that many social and historical forces must come together before the ideals of the critical thinking movement will become a full academic reality. Schools do not exist in a social vacuum. To the extent that the broader society is uncritical so, on the whole, will be society's schools. Nevertheless, the social conditions necessary for fundamental changes in schooling are increasingly apparent. The pressure for fundamental change is growing. Whether and to what extent these needed basic changes will be delayed or side-tracked, thus requiring new periodic resurgences of this movement, with new, more elaborate articulations of its ideals, goals, and methods — only time will tell.     

Back to the future: Temporal perspective in the explanation of events

Prospective hindsight involves generating an explanation for a future event as if it had already happened; i.e., one goes forward in time, and then looks back. In order to examine how shifts in perspective might influence people's perceptions of events, we investigated two possible factors: temporal perspective (whether an event is set in the future or past) and uncertainty (whether the event's occurrence is certain or uncertain). In the first experiment, temporal perspective showed little influence while outcome uncertainty strongly affected the nature of explanations for events. Explanations for sure events tended to be longer, to contain a higher proportion of episodic reasons, and to be expressed in past tense. Evidence from the second experiment supports the view that uncertainty mediates not the amount of time spent explaining, but rather subjects' choice of explanation type. The implications of these findings for the use of temporal perspective in decision aiding are discussed.     

Predicting a changing taste: Do people know what they will like?

A distinction is made between decision utility, experienced utility, and predicted utility and an experiment is reported addressing people's ability to forecast experienced utility. Subjects in two experiments made predictions of their future liking for stimuli to which they were then exposed daily for one week. The stimuli were ice cream in a pilot study, plain yogurt in the main study, and short musical pieces in both studies. Decreased liking was the modal prediction, even when the true outcome was increased liking, or reduced dislike. There was substantial stability of tastes, but there were also substantial individual differences in the size and even the sign of changes in liking with repeated exposure. There was little or no correlation between the predictions of hedonic change that individuals made and the changes they actually experienced.     

On the assessment of genetic technology: Reaching ethical judgments in the light of modern technology

The “Model for Reaching Ethical Judgments in the context of Modern Technologies — the Case of Genetic Technology”, which is presented here, has arisen from the project “Ethical Criteria bearing upon Decisions taken in the field of Biotechnology”. This project has been pursued since 1991 in the Zentrum für interdisziplinäre Technikforschung (ZIT) of the Technical University of Darmstadt, with the purpose of examining decision-making in selected activities involving the production of transgenic plants that have a useful application. The model is the basis of an outline for interviews to investigate how far decisions concerning the development of such plants with genetic techniques take ethical criteria into account. It was necessary to design this new model because other models for reaching judgments of this kind were not conceptually suited for concrete application. This model represents a problem related approach and combines methodological with substantive typology. In this it differs from comparable models for reaching ethical judgments.     

The temporal–hippocampal region and retention: The role of temporo-entorhinal connections in rats

Results from previous studies suggest that the entorhinal cortex may be involved in mnemonic processes. The present study was carried out to investigate whether disruption of fibre connections between the temporal cortex and lateral entorhinal area may impair retention of a pre-operatively acquired simultaneous brightness discrimination task. The lesion resulted in a severe impairment in retaining the discrimination task (Experiment 1). The retention deficit could not be traced into the hippocampal formation by making perforant path lesions or hippocampal lesions (Experiment 2). The results indicate that the lateral entorhinal cortex is more crucial for reference memory than the hippocampal formation.
