An experimental study of the relative identification thresholds of nine American vowels

As a result of the controversy over the dimensionality of the ethos/source credibility construct and the associated plethora of empirical studies in the 1960s and 1970s, Aristotle's dimension of “goodwill” has been dismissed by many contemporary theorists and researchers. It is argued that this occurred as a result of errors made in the earlier empirical research and that “goodwill” can be measured, contrary to earlier claims, and should be restored to its former status in rhetorical communication theory. Empirical research is reported indicating the existence of the goodwill dimension as part of the structure of the ethos/source credibility construct and a measure of that dimension is provided with evidence for its reliability and validity.

Information and library science MPACT: A preliminary analysis

Dissertation advising is an important form of mentoring. To investigate the impact of dissertation advising over time, advisor and committee member names were collected for 2400 dissertations completed over a 40-year period (1964–2004) in 32 North American information and library science schools. Several mentoring impact metrics are reported for a subset of the data, including the number of dissertations advised, the number of dissertation committees served on, the ratio of advising to committee membership, and the fractional “mpact” that weights advising and committee membership. The subset consists of data for six schools that produced at least three dozen dissertations and for which complete data is available. The data and resulting “mpact” metrics offer new ways to assess faculty impact and to investigate the nature and growth of a field.

A multiple-case study investigation of the discontinuation of nine chat reference services

Using the multiple-case study method, this research investigates reasons why nine virtual reference (chat) services have been discontinued. The investigation of these five academic, one public, and three consortial chat services was conducted through structured e-mail and telephone interviews with the library decision makers and analysis of available reports and documents. The major reason for discontinuation was funding problems, followed by low volume (including low volume by target audience). Other reasons were staffing problems, technical problems, and institutional culture issues. Staffing issues included the need for comfortable staffing patterns, maintenance of sufficient volume to maintain proficiency, and cultivation of positive attitudes. Technical problems centered on software malfunctions and connectivity difficulties. Within two of the consortia, different patterns of funding, staffing, and mission posed difficulties for blended cultures that caused the consortia to break up. Despite all these issues, the possibility of restarting chat services, perhaps in consortia or with simpler chat software, exists for all services, with two services desiring to restart when funds and reorganization permit.     

Oral and nasal sound pressure levels of vowels

A method of classifying group interaction content themes wasdeveloped which operationalized an analytic paradigm taken from Talcott Parsons. Results of data analysis for two independent observers showed the method to be reliable. Additional analyses showed that groups studied exhibited a well defined distributional thematic structure but less articulated sequential thematic structure.

A preliminary study of the verbal behavior of speech fright

A general paradigm of a rating error theory is presented with a study testing relationships from the theory. The study aimed to discover the effects of source credibility, attitude valence, and task sensitization on trait errors in the evaluation of speeches. The main hypothesis of the study was an interaction effect on trait errors in the speech ratings. The results indicate a significant triple interaction, suggesting that when speech raters are sensitized to the task and are in favor of the view of the speaker, their trait errors on “ideas” will favor a low credibility speaker. The results are explained in terms of attraction and similarity.
