Normal Versus Noncentral Chi-square Asymptotics of Misspecified Models

In this article, we present a Bayesian spatial factor analysis model. We extend previous work on confirmatory factor analysis by including geographically distributed latent variables and accounting for heterogeneity and spatial autocorrelation. The simulation study shows excellent recovery of the model parameters and demonstrates the consequences of ignoring spatial dependence. Specifically, we find inefficiency in the estimates of the factor score means and bias and inefficiency in the estimates of the corresponding covariance matrix. We apply the model to Schwartz value priority data obtained from 5 European countries. We show that the Schwartz motivational types of values, such as Conformity, Tradition, Benevolence, and Hedonism, possess high spatial autocorrelation. We identify several spatial patterns—specifically, Conformity and Hedonism have a country-specific structure, Tradition has a North–South gradient that cuts across national borders, and Benevolence has South–North cross-national gradient. Finally, we show that conventional factor analysis may lead to a loss of valuable insights compared with the proposed approach.     

Perfectionism, beliefs, and adjustment in dating relationships

Two studies examined the extent to which dimensions of perfectionism are associated with indices of relationship beliefs, behaviors, and dyadic adjustment. In Study 1, 69 students in dating relationships completed the Multidimensional Perfectionism Scale (MPS) and a multidimensional measure of relationship beliefs. In addition, partici-pants completed self-report measures of positive and negative relationship behaviors, and global measures of liking and loving. In Study 2, 91 students in dating relation-ships completed a battery of measures including the MPS and scales assessing perfec-tionism cognitions and perfectionistic self presentation. They also completed mea-sures of dyadic adjustment and limerence (i.e., intense, obsessive low with fears of rejection). Collectively, the findings indicated that individuals with high levels of self-oriented perfectionism and other-oriented perfectionism have stronger relationship beliefs in the areas of communication, trust, and support, suggesting that these perfec-tionists have high relationship standards in these particular areas. Although social prescribed perfectionism had little association with specific relationship beliefs, so-cially prescribed perfectionism was associated with a tendency to display destructive relationship responses (i.e., exit, neglect, and insensitivity), lower dyadic adjustment, and various aspects of limerence, including obsessive preoccupations and emotional dependence on the dating partner. Perfectionistic self-presentation and perfectionism cognitions were also linked with aspects of limerence. The results suggest that inter-personal aspects of perfectionism are associated with self-defeating tendencies in dating relationships.

Remarks on the development of computability

The purpose of this article is to examine aspects of the development of the concept and theory of computability through the theory of recursive functions. Following a brief introduction, Section 2 is devoted to the presuppositions of computability. It focuses on certain concepts, beliefs and theorems necessary for a general property of computability to be formulated and developed into a mathematical theory. The following two sections concern situations in which the presuppositions were realized and the theory of computability was developed. It is suggested in Section 3 that a central item was the problem of generalizing Gödel's incompleteness theorem. It is shown that this involved both the characterization of recursiveness and the attempt to clarify and formulate the notion of an effective process as it relates to the syntax of deductive systems. Section 4 concerns the decision problems which grew from the Hilbert program. Section 5 is devoted to the development of an informal' technique in the theory of computability often called ‘argument by Church's thesis’.     

An experimental investigation of justice-based service recovery on customer satisfaction, loyalty, and word-of-mouth intentions

Service recovery is related to many important organizational outcomes such as customer satisfaction, loyalty, and profitability. Within the theoretical framework of organizational justice, an experiment using a simulated "live" service failure was used to assess the effects of justice-based service-recovery strategies on customer satisfaction, loyalty, positive word-of-mouth intentions, and negative word-of-mouth intentions. Analysis indicated that strategies including interactional justice, distributive justice, and a combination of these were equally effective in maintaining customer satisfaction, loyalty, and positive word of mouth, and minimizing negative word of mouth after a service failure. No support for the service recovery paradox, that is, increased satisfaction following service failure and recovery compared to never having a problem, was found. Satisfaction and loyalty for those in the failure conditions were equal to, although not higher than, in the no-failure control condition. Practical implications for organizational practices are discussed.     

Practical Modes of Presentation

The Intellectualist thesis that know‐how is a kind of propositional knowledge faces a simple problem: For any proposition p, it seems that one could know p without knowing how to do the activity in question. For example, it seems that one could know that w is a way to swim even if one didn't know how to swim oneself. In this paper I argue that this “sufficiency problem” cannot be adequately addressed by appealing to practical modes of presentation.     

Prosodic influences on the resolution of temporary ambiguity during on-line sentence processing

We present three experiments designed to investigate the role of prosody during sentence processing. The first investigated the question of whether an utterance's prosodic contour influences its comprehension on-line. We spliced the beginning and end portions of direct object and embedded clause sentences and observed the consequent effects on comprehension using a dual-task procedure to measure processing load. Our second experiment sought to determine-whether the constituent structure of these sentences could be reliably predicted using prosodic information. We found that the duration and F₀ contour associated with the main-clause verb and the following NP reliably distinguished between the direct object and embedded clause constructions. In the final experiment, we manipulated the duration of the main-clause verb and found that subjects used this information to guide their initial parse during on-line sentence comprehension. The need for a model of sentence processing that addresses the use of prosodic information is discussed.The work reported in this paper was supported in part by NTH grant DC00494.     

Determining the degree of inconsistency in a set of paired comparisons

Consistency in paired comparison data is defined. Two types of inconsistency which may arise are defined. Computational formulas for these types of inconsistency are derived, and examples illustrating the use of these formulas are presented.These ideas were developed while the first author was on the staff of the Research Center for Human Relations. The work was made possible by the ONR contract NONR 285(10). The authors are indebted to Jack Moshman for his helpful critical suggestions.

Perception and immediate recall of normal and “compressed” auditory sequences

For a fixed presentation rate, the ratio of speech-to-pause time was varied in three experiments. Ss recalled seven-digit sequences or monitored for item or order information in addition to recall. Removing 33% of the speech and substituting pause time improved recall accuracy and monitoring reaction times. The data suggest that loss of order information in recall may result from cumulative perceptual delays when adequate pause time is unavailable.
