The narrative worlds of what is and what if

This paper advances the hypothesis that young children use narrative play and stories to construct two types of fiction, the worlds of what is and what if. Heinz Werner's conceptualization of children's spheres of reality, in which actions, symbols, and events are constructed in particular ways, is used as a theoretical framework for understanding children's play and stories. Drawing on examples of children's spontaneous pretend play and story telling, the paper argues that, beginning in their second year, children use pretend play to differentiate the worlds of everyday-lived reality from an alternative pretend sphere; the world of as if. By their third year, children engage in play which hangs on a narrative framework. Such pretend play offers children further options: the fictional world of plausible make believe which simulates everyday life, what is, and the fictional world of more fantastic possibilities, what if. While the child's use of a narrative framework in her pretend play expands her range of psychological worlds, the developmental shift to purely verbal stories, sometimes during the child's third year, significantly adds to her ability to explore such worlds. An examination of the language young children use to accompany their narrative play and to tell stories demonstrates the ways in which children exploit the narrative form to contrast, compare, and traverse the constructed worlds of what is and what if.     

Laws, Ceteris Paribus Conditions, and the Dynamics of Belief

The characteristic difference between laws and accidental generalizations lies in our epistemic or inductive attitude towards them. This idea has taken various forms and dominated the discussion about lawlikeness in the last decades. Likewise, the issue about ceteris paribus conditions is essentially about how we epistemically deal with exceptions. Hence, ranking theory with its resources of defeasible reasoning seems ideally suited to explicate these points in a formal way. This is what the paper attempts to do. Thus it will turn out that a law is simply the deterministic analogue of a sequence of independent, identically distributed random variables. This entails that de Finetti's representation theorems can be directly transformed into an account of confirmation of laws thus conceived.

Ceteris Paribus Post

Many have claimed that ceteris paribus (CP) laws are a quite legitimate feature of scientific theories, some even going so far as to claim that laws of all scientific theories currently on offer are merely CP. We argue here that one of the common props of such a thesis, that there are numerous examples of CP laws in physics, is false. Moreover, besides the absence of genuine examples from physics, we suggest that otherwise unproblematic claims are rendered untestable by the mere addition of the CP operator. Thus, “CP all Fs are Gs” when read as a straightforward statement of fact, cannot be the stuff of scientific theory. Rather, we suggest that when ``ceteris paribus' appears in scientific works it plays a pragmatic role of pointing to more respectable claims.

Intellectual differences among Mexican Americans, Papagos and Whites, independent of g

Patterns of intellectual abilities for Mexican American and Native American Papago children were contrasted with those of White children, independent of overall differences in ability. Large differences in highly verbal skills remained, with Whites consistently outscoring the other two groups. Native Americans showed higher performance than Whites on spatial-visualization tasks but Mexican Americans exceeded Whites on no tasks. These race-related patterns of ability are nearly opposite those found in Black–White comparisons.     

The Being of Leadership

The ethical foundation of the medical profession, which values service above reward and holds the doctor-patient relationship as inviolable, continues to be challenged by the commercialization of health care. This article contends that a realigned leadership framework - one that distinguishes being a leader as the ontological basis for what leaders know, have, and do - is central to safeguarding medicine's ethical foundation. Four ontological pillars of leadership - awareness, commitment, integrity, and authenticity - are proposed as fundamental elements that anchor this foundation and the basic tenets of professionalism. Ontological leadership is shaped by and accessible through language; what health care leaders create in language "uses" them by providing a point of view (a context) within and from which they orient their conversations, decisions, and conduct such that they are ethically aligned and grounded. This contextual leadership framework exposes for us the limitations imposed by our mental maps, creating new opportunity sets for being and action (previously unavailable) that embody medicine's charter on professionalism. While this leadership methodology contrasts with the conventional results-oriented model where leading is generally equated with a successful clinical practice, a distinguished research program, or a promotion, it is not a replacement for it; indeed, results are essential for performance. Rather, being and action are interrelated and their correlated nature equips leaders with a framework for tackling health care's most complex problems in a manner that preserves medicine's venerable ethical heritage.
