The Concept of Consciousness4 The Reflective Meaning

In this article, which is fourth in a series of six articles, I address the fourth concept of consciousness that the Oxford English Dictionary ("the OED") defines in its six main entries under the word consciousness. I first introduce this fourth concept, the concept of consciousness₄. by (a) identifying the previous three OED concepts of consciousness, which I have already discussed in this series of articles, and (b) by indicating how that to which we make reference, respectively, by means of those three concepts is related to the referents of the concept of consciousness₄. I then address the latter concept more directly by pursuing for the remainder of the article where the OED's fourm entry leads. Among other things, I am led to consider two competing accounts of consciousness₄ that figure prominently in the OED entry, namely the intrinsic, self-intimational account of William Hamilton and the inner-eye, perceptionlike account of John Locke. Both kinds of account are very much with us today.     

Markov Properties for Acyclic Directed Mixed Graphs

We consider acyclic directed mixed graphs, in which directed edges ( x → y ) and bi-directed edges ( x ↔ y ) may occur. A simple extension of Pearl's d -separation criterion, called m -separation, is applied to these graphs. We introduce a local Markov property which is equivalent to the global property resulting from the m -separation criterion for arbitrary distributions.     

The Concept of Consciousness5: The Unitive Meaning

This is the fifth of a series of six articles examining respectively the six concepts of consciousness identified in the main entries of the Oxford English Dictionary under the word. I call the concept of consciousness₅ the unitive meaning because it is said to refer to the totality of mental-occurrence instances that constitute a person's conscious being. The present article consists mainly of an effort to answer the question of which totality of mental-occurrence instances it is to which the fifth concept refers. Four possible answers are considered, and the fourth, derived form Locke, is found to capture best the dictionary's meaning. Accordingly, consciousness5 is a certain subjectively determined unity of mental-occurrence instances mat is further specified, of course, in the article. However, I also consider, finally, that the compilers of the dictionary may have had something more objective in mind as well, another meaning toward which the word is tending if it has not already arrived mere. This further sense may amount to an identification of consciousness with those components of James's stream that he described as "the very core and nucleus of our self as we know it, the very sanctuary of our life."     

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989

All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates.     

WAR AND PESTILENCE AS LABOR MARKET SHOCKS: U.S. MANUFACTURING WAGE GROWTH 1914–1919

This paper explores the effect of mortalities from the 1918 influenza pandemic and World War I on wage growth in the manufacturing sector of U.S. states and cities from 1914–1919. The hypothesis is that both events decreased manufacturing labor supply, thereby initially increasing the marginal product of labor and wages. The results reveal that states and cities having had greater influenza mortalities experienced higher wage growth—roughly 2–3 percentage points for a 10% change in per capita mortalities. World War I combat mortalities also had a positive, but smaller, effect on wage growth. ( JEL N62, N32, N92, I12)     

Covariate Selection for the Semiparametric Additive Risk Model

Abstract.  This paper considers covariate selection for the additive hazards model. This model is particularly simple to study theoretically and its practical implementation has several major advantages to the similar methodology for the proportional hazards model. One complication compared with the proportional model is, however, that there is no simple likelihood to work with. We here study a least squares criterion with desirable properties and show how this criterion can be interpreted as a prediction error. Given this criterion, we define ridge and Lasso estimators as well as an adaptive Lasso and study their large sample properties for the situation where the number of covariates p is smaller than the number of observations. We also show that the adaptive Lasso has the oracle property. In many practical situations, it is more relevant to tackle the situation with large p compared with the number of observations. We do this by studying the properties of the so-called Dantzig selector in the setting of the additive risk model. Specifically, we establish a bound on how close the solution is to a true sparse signal in the case where the number of covariates is large. In a simulation study, we also compare the Dantzig and adaptive Lasso for a moderate to small number of covariates. The methods are applied to a breast cancer data set with gene expression recordings and to the primary biliary cirrhosis clinical data.     

An analysis of variance type test for comparing clusters of DNA sequences based on randomization test methodologies

SUMMARY A method for comparing groupings of DNA sequences is presented, which utilizes randomization test methods to assign significance levels to a test statistic defined in terms of the Hamming distance between two sequences. The method, which is intuitively motivated by the analysis of variance procedure, partitions the variation caused by differences between clusters from the variation attributable to differences at random base pair locations within clusers. Implementation issues are discussed, and an example of the application of the method is provided.     

Developing a Community Attitude Assessment Scale

The Community Attitude Assessment Scale (CAAS) measures citizens'attitudes toward 15 community Life Areas (e.g., Education, Employment,and Health) on four dimensions—Importance, Influence,Equality of Opportunity, and Satisfaction. Residents generallyrate these Life Areas high on Importance and Equality of Opportunity,but feel only limited Satisfaction with them and perceive themselvesas having fairly low Influence on their operations. The scaleis discussed as an instrument, and in terms of community theory,attitude theory and research, and public policy applications
