Graphical Methods for Data Presentation: Full Scale Breaks,Dot Charts,and Multibased Logging

Experimentation with graphical methods for data presentation is important for improving graphical communication in science. Several methods—full scale breaks, dot charts, and multibased logging—are discussed. Full scale breaks are suggested as replacements for partial scale breaks, since partial breaks can fail to provide a forceful visual indication of a change in the scale. Dot charts show data that have labels and are replacements for bar charts; the new charts can be used in a wider variety of circumstances and allow more effective visual decoding of the quantitative information. Logarithms are powerful tools for data presentation; base 2 or base e is often more effective than the commonly used base 10.     

KIDS OR CASH? EXPLORING CHARTER SCHOOL RESPONSES TO DECLINING GOVERNMENT REVENUES

While the literature is extensive on school districts' revenue sources, less research has been done on the impact of donations on school district funds. In this paper, we extend the theoretical literature on crowding out of private donations by government grants for one type of nonprofit firm, namely charter schools. The theoretical model leads us to focus on the key relationships among fundraising effort, enrollment (which is tied to federal and state funding) and donations. Using a dataset on Texas charter schools we adopt a two-stage approach to examine the empirical relationship between changes in nondonor revenues and the donations received by charter schools. Like the extensive empirical estimates of the effects of government grants on donations for other types of nonprofit firms, we find evidence of crowding-out with respect to our sample of charter schools. We also find a significant, positive effect of fundraising on donations with a $1 increase in fundraising associated to a $0.58 increase in donations, a pattern consistent with overinvestment in fundraising. Enrollments exhibit a robust inverse relationship to changes in nondonor revenues. (JEL H00, H32, H50)     

The Incident: Not Just Another Organizational Disruption

Issue and crisis: These concepts are well-understood, even though various definitions exist. A third concept, incident, is less defined. This article reports a content analysis of articles from two public relations journals (n = 67) and three prominent public relations industry publications (n = 56) to understand how incident is contextualized and applied. Findings reveal a statistically significant difference in how academic and industry publications contextualize the concept and expose a need for a formal conceptualization. Building on the results of the analysis, this article, then, argues that incident is (a) defined as a theoretical concept and pragmatic communication-management matter, (b) implemented within a continuum of organizational disruption, (c) presented as a necessary concept for greater precision for the reporting and analyzing of disruptive events, and (d) needs to be included in future scholarly research about and models of disruptive events.     

Harmful Algal Blooms in South Carolina Residential and Golf Course Ponds

The South Carolina coastal zone is among the fastest growing areas in the U.S., and population epicenters are marked by dense brackish water pond (lagoon) coverage associated with housing complexes and golf courses. Surveillance efforts in 2001–2002 documented the widespread occurrence of several types of potentially or measurably toxic harmful algal blooms (HABs) in these ponds. These man-made retention ponds were constructed in order to serve as a buffer between developed areas and open estuaries or for aesthetic reasons. However, the combination of restricted tidal flow and nutrient and/or contaminant deposition creates a stimulatory environment for potential HAB formation. These discoveries introduce the need to consider mitigation measures to existing ponds and HAB preventive strategies for future pond construction.     

Cairo and the changing definition of population and development issues

The goal of the United Nations International Conference on Population and Development (ICPD), held in Cairo in September 1994, was to agree on a Programme of Action in the field of population and development which would supersede the Plan of Action agreed to at Bucharest in 1974 and subsequently amended ten years later in Mexico City. The main purpose of the present paper is to characterize some of the principal intellectual and ideological developments of the last 20 years which have had an impact on the definition of this goal. I conclude with some brief comments on the Programme of Action adopted by consensus at the Conference. This is an amended version of the paper I presented at the Seventh National Conference of the Australian Population Association (in a Plenary Session entitled ‘Messages from Cairo’), held in Canberra in September 1994.     

Circular and linear modeling of female sexual desire and arousal

There is debate in the scientific literature regarding which model most accurately represents the female sexual response. Traditionally, sex research has been conducted within the framework of the linear sexual response model proposed by Masters and Johnson, modified by Kaplan, then Robinson. Criticism of linear models prompted the development of a composite model of the female sexual response by Basson et al., which included linear and circular pathways. This review aims to systematically assess published studies to determine the extent to which circular and linear models or pathways reflect the female sexual response. Medline, EMBASE, and PsychINFO databases were searched for original data papers and review articles. Inclusion criteria were that articles were published since 1990, in English, and compared linear and circular sexual response models or addressed aspects of these models. Reviews were required to be systematic and include a meta-analysis. Of the 898 studies identified through the initial literature search, 13 original studies and one review met the inclusion criteria. Two studies directly compared models providing limited evidence that most women identify with linear sexual response pathways. However, there is increasing evidence that circular pathways may accurately reflect some aspects of the female sexual response. Further comparative studies are encouraged.     

Stigmatizing Indebtedness: Implications for Labeling Theory

Given the low visibility of indebtedness and normative expectations regarding the use of credit and the accrual of debt, questions arise as to whether or not being unable to manage one's finances responsibly should necessarily lead a person to feel shame. Findings from a study, based on forty‐six interviews with members of Debtors Anonymous (DA), exploring the relevance of labeling theory to individual perceptions of one's indebtedness as shameful are presented. Shame is revealed to be a key element in the labeling process. How stigmatized labels arise in interaction, how such labels affect a person's thoughts, feelings, and actions, and how gender affects labeling experiences are discussed. Insights into the interconnections between labeling and shame show the labeling process to be considerably more complex than suggested in the original version of labeling theory.     

Requirements for successful implementation of new manufacturing technologies

This paper addresses the issue of why many U.S. companies have had major problems implementing “programmable automation” technologies in a manner to exploit their full potential. Many competitors in Japan and Europe have been much more successful. The theme of the paper is that the real impediment to the effective use of this new manufacturing hardware lies in some deeply entrenched attitudes and ways of doing things that are incompatible with the requirements and unique capabilities of the new hardware. Barriers to successful implementation are explored and implications for managerial practice are discussed.
